201103484 六、發明說明： 【發明所屬之技術領域】 本發明係有關電氣吸塵器，特別是關於旋風式之電氣 吸塵器者。 【先前技術】 作爲以往的技術專利，於文獻1，記載有一於塵埃分 離室的下側配置塵埃容納室，塵埃分離室內的吸氣筒外側 的含塵空氣流入塵埃容納室，在塵埃容納室內除去質量較 大的粗砂垃圾等之後，夾介吸氣筒下端的第1過濾器被從 吸氣筒下端開口吸入並通過吸氣筒內，且夾介第2過濾器 被電動送風機吸附之電氣吸塵器。再者，記載有於吸氣筒 的同心圓上設置外筒，於其下端設置壓縮板，若使外筒與 壓縮板一同降下則蓄積於塵埃容納室內之塵埃會藉由壓縮 板被壓縮，而設置於外筒的內周面之刷毛會把附著在形成 於吸氣筒的過濾器之塵埃刮落者。 於專利文獻2，記載有一於集塵殼體內並列配置分離 室及塵埃容納部，分離室內之內筒外的空氣爲從分離室流 入塵埃容納部，與分離室內之內筒內的空氣合流，並夾介 網狀之網狀過濾器及褶狀之過濾器，被吸附於電動送風機 之電氣吸塵器。再者，記載有在丟棄蓄積於網狀之網狀過 濾器並藉由吸氣被壓縮的塵埃時，網狀的網狀過濾器及褶 狀的過濾器係以下端爲軸來轉動打開。 於專利文獻3，記載有一於集塵殼體內部設置用以捕 201103484 集塵埃的塵埃容納器’在丟棄蓄積於塵埃容納器並藉由吸 氣被壓縮的塵埃時，塵埃容納器係以下端爲軸一面轉動一 面從集塵殼體彈出並且瓦解成上下部的電氣吸塵器。 於專利文獻4’記載有一於圓筒狀的旋風機體之一側 ’形成有用以將髒污空氣朝軸方向吸入之吸入口，於另一 側形成有使淨化後的空氣朝軸方向排出之空氣排出口，而 ，於旋風機體的內部，設置有使被吸入軸方向的空氣朝接 線方向迴轉之迴轉力賦予手段，於排出口側，設置有把藉 由離心力所分離之髒污物朝向接線方向引導之髒污物排出 口 ’於上述髒污物排出口的一端係以可裝卸之方式設置集 塵箱之順流方向旋風集塵裝置。 於專利文獻5，記載有一具備有旋風集塵器之電氣吸 塵器’該旋風集塵器係爲了使在旋風部的內部產生之迴旋 流的迴轉軸爲大致朝水平方向延伸而橫放配置。而於專利 文獻5’記載有一來自地板用吸入口之含有塵埃的空氣在 從旋風集塵器的吸入口通過蓋的半周分的流路時成爲迴旋 流並夾介開口被導入旋風部，接著沿著旋風集塵器的內周 壁’藉由中筒之傘狀的分隔板，塵埃被與空氣分離，並被 集塵於集塵部，另一方面，藉由前述的迴旋流而被淨化的 空氣’第1次通過網狀過濾器再被淨化，接著通過中筒內 部’第2次到達過濾器，又，與塵埃一同進入集塵部的空 氣’在第1次通過網狀過濾器時，將集塵部內部的塵埃予 以壓縮，第1次通過網狀過濾器被淨化的空氣，第2次到達 過濾器’其後，通過中筒內外之空氣，被2次藉由過濾器 -6- 201103484 過濾後，而到達電動送風機。 於專利文獻6，記載有一藉由將所謂殼體及內殼體之2 個殻體予以組合，而形成迴旋流路、並連流路以及集塵空 間之電氣吸塵器用之塵埃容器。然後，於專利文獻6 ’記 載有於內殼體，包含有接受從吸氣口進入的空氣之緩衝空 間，將緩衝空間的空氣朝順時針方向誘導之迴旋流路形成 部，及於迴旋流路形成部的內側朝前方方向突出設置之半 柱狀的凸部，於半柱狀凸部的周面上，在靠近迴旋方向下 游的周面設置有多數之穿透的通氣用小孔，從吸氣口進入 緩衝空間的空氣及塵挨，主要沿著迴旋流路形成部一面向 右迴旋一面朝向下游側流動，以凸部爲中心迴旋，而迴旋 之空氣的一部分，爲通過形成於凸部之多數的通氣用小孔 並朝向背面側流動者。 又，於專利文獻6及專利文獻9，記載有一藉由在迴旋 流路的下游側周圍區劃集塵空間，塵埃會從集塵空間的外 側蓄積起來，另一方面，藉由在迴旋流路的下游側具備有 內殻體之圓滑膨出之引導面，使塵挨幾乎不會附著於引導 面，即使是在集塵空間的周圍蓄積很多塵埃的狀態，於迴 旋流路也可進行空氣的迴旋，因此，即使是在集塵空間蓄 積很多塵埃的狀態，也不會妨礙迴旋流路本身的空氣流動 ，空氣會迴旋，吸引力也幾乎沒有降低者。 於專利文獻7，記載有一具備有在將集塵殼體收納於 吸塵器本體時，彈性密封部並非設置於垂直方向，而是其 上側傾斜於電動送風機側地設置，因此，藉由將集塵殻體 201103484 緊壓於吸塵器本體入，可易於取得氣密性，並且易於從吸 塵器本體裝卸集塵殻體的旋風分離式集塵部之電氣吸塵器 。又，於專利文獻7，記載有一在將旋風分離筒及集塵殼 體構成一體，並安裝於吸塵器本體時，考慮卸下之方便性 ，上部的前後方向，以比下部的前後方向長度還長之方式 設置拔模角。與此相應，過濾器殼體也相對於地板面，傾 斜地配置，故過濾器殼體的下側比起上側，其前後方向爲 較長者。 於專利文獻8，亦記載有一集塵裝置收納室，隨著前 側壁面之越上方處越朝前側傾斜地形成，後側壁面爲大致 垂直地形成，集塵裝置收納室爲隨著越上方變得越寬地形 成，而於集塵裝置之收納時，引導集塵裝置能被圓滑地收 納的電氣吸塵器。 作爲以往的技術，爲於非專利文獻，記載有一在與一 般掃除時同樣地將吸塵器本體橫放時，使大致圓筒形狀之 灰塵杯體的軸傾斜地配置於吸塵器本體前部，馬達及電線 捲軸爲以相鄰之方式配置於吸塵器本體後部，於灰塵杯體 上部且於吸塵器本體上部設置抗敏物質HEP A清淨過濾器 ，於吸塵器本體大致中央部、馬達前、電線捲軸旁且爲馬 達的下游，設置有與馬達爲相同寬幅之可裝卸的排氣 HEP A清淨過濾器之電氣吸塵器。 〔先行技術文獻〕 〔專利文獻〕 ⑧ -8- 201103484 〔專利文獻1〕 曰本特開2003-190056號公報 〔專利文獻2〕

者不得不藉由操作控制桿來操作壓縮板，故使用者的負擔 較大。 在此，代替專利文獻1的第1過濾器，使其朝上側開口 地而考慮設置了專利文獻3的塵埃容納器，不過於專利文 獻1，由於流入塵埃容納室內的空氣爲從吸氣筒下端開口 被吸入，故蓄積於專利文獻3之麈埃容納器的塵埃，亦與 該空氣一同被從吸氣筒下側吸入，其結果，朝向電動送風 -9 - 201103484 機前的第1過濾器蓄積的塵埃蓄積量變多，吸引力有降低 之虞。 在專利文獻2中，由於是將分離室與塵埃容納部並列 配置，故無法擴大分離室及其內筒的口徑，因而會隨著塵 埃往塵埃容納部的蓄積而更增大要從分離室內的內筒進行 吸氣的期望度，而使得吸氣的壓力損失變大，其結果，相 較於沒有蓄積塵埃之初期狀態，吸引力有降低之虞。又， 於專利文獻2，由於網狀的網狀過濾器爲平面狀，故有使 用者無法容易地除去緊貼於網狀的網狀過濾器的塵埃之虞 〇 在此，代替專利文獻2之網狀的網狀過濾器，而考慮 設置了專利文獻3的塵埃容納器，不過專利文獻3的麈埃容 納器爲呈容器形狀，故有集塵外殼後部的形狀變大之虞。 又，在使用者拿著專利文獻2的把手將集塵外殼後部打開 時，由於專利文獻3的塵埃容納器之彈出方向，對於使用 者而言爲近身（把手）側，故塵埃容納器內的塵埃會卡到 專利文獻2的塵埃容納部的後部而不能順利排出，再者， 彈出之塵埃容納器本身會碰撞到塵埃容納部的後部而有塵 埃容納器本身不能順利彈出之虞。 又，於專利文獻3，即使爲塵埃容器從集塵外殼彈出 之狀態，塵埃容器的後部也是抵接於集塵外殼內，故彈出 之塵埃容器的前側之開口部的形成方向，相較於水平方向 爲更近於垂直方向，而有塵埃殘留於塵埃容器內之虞。又 ，使用者，爲了使塵埃容器的前側之開口部朝向下側方向 -10- 201103484 ，欲使握把朝向下側方向必須轉動手腕，而有使用者的負 擔變大之虞。又，於專利文獻3，由於將集塵容器的轉動 軸直接形成於集塵外殻的內側下表面，故會有強度不足， 或集塵外殼的下表面彎曲，而損害外觀之虞。 於專利文獻4，由於爲了使旋風流產生，而必需迴轉 力賦予手段，故旋風集塵裝置的軸方向的長度會變得較長 ，其結果，會有吸塵器本體之前後方向的長度變長之虞。 例如，相對於旋風機體將集塵箱鄰接軸方向地配置時，旋 風集塵裝置的軸方向之長度會變得更長，其結果，吸塵器 本體的前後方向之長度也會變得更長。又，於專利文獻4 ，由於在流路從污染空氣吸入口擴大而流速降低後，會賦 予污染空氣迴轉力，故迴轉速度變慢，而離心力降低，會 有無法充分將污染空氣分離之虞。又，於專利文獻4，由 於從迴轉力賦予手段到排出口的筒部之間很長，而空氣從 迴轉力賦予手段到排出口的筒部之間多重迴旋，故空氣的 能量損失較大，又，亦有產生噪音之虞。又，於專利文獻 4’由於迴轉力賦予手段爲由複數個翼（散熱片）所形成 ’故空氣的能量損失較大，又，亦有產生噪音之虞。又， 於專利文獻4，由於沒有設置從集塵箱朝向外部的排氣口 ’從旋風機體排出的排氣僅爲相當於內筒之小徑的排氣口 ’故排氣空氣的能量損失較大。又，於專利文獻4，由於 沒有設置將蓄積於集塵箱的塵埃予以壓縮的手段，故集塵 箱的塵埃容納量較少。 於專利文獻5，由於在配置於中筒前端的前側之蓋內 -11 - 201103484 ，形成有使迴旋流產生的流路，故旋風集塵器的水平方向 (軸方向）的長度會變得較長，其結果，會有吸塵器本體 的前後方向的長度變長之虞。又，由於中筒之形成有1次 性網狀過濾器之部分的形狀爲三角錐，故隨著越朝向水平 方向（軸方向）的下游側接近（隨著從三角錐的頂部越朝 底部接近），塵埃越易於附於1次性網狀過濾器的表面， 而有吸引力降低之虞》 於專利文獻6，由於在半柱狀之凸部的半徑方向的外 側，形成有緩衝空間及迴旋流路形成部，故集塵室的半徑 方向（上下左右方向）的長度會變得較長，其結果，會有 吸塵器本體的前部的高度及橫向寬幅變得較大之虞。 於專利文獻7及專利文獻8，沒有記載旋風分離筒及集 麈外殼之間的密封機構，因此，相對於集塵外殼之排氣側 開口的彈性密封部的形成方向（非垂直方向，上側爲傾斜 於電動送風機側），於旋風分離筒及集塵外殼的接合面大 幅傾斜之場合，於旋風分離筒與集塵外殼之間單僅使密封 構件介在其中，會有不能得到充分氣密之虞。 記載於非專利文獻的排氣HEP A清淨過濾器，爲可去 除藉由抗敏物質HEP A清淨過濾器不能完全去除之本體內 部的細密的塵埃，可使通過排氣HEP A清淨過濾器之排氣 更乾淨，不過雖可去除細密塵埃，卻因此有壓力損失較大 之虞。 爲了減少壓力損失，必須增加過濾器的面積。但是記 載於非專利文獻之排氣HEPA清淨過濾器由於爲設置於電 ⑧ -12- 201103484 線捲軸旁，故除了加寬吸塵器本體的寬幅之手段以外，要 將過濾器的面積加大，在構造上是很難。 又，記載於非專利文獻之排氣HEPA清淨過濾器沒有 被固定，爲可裝卸。因此，在將排氣HEP A清淨過濾器裝 著於吸塵器本體時，於馬達與排氣HEPA清淨過濾器之間 會產生細微的縫隙，會有不能去除細密的塵埃之虞。 在此，本發明之目的，爲提供一種不用煩勞使用者的 手即可壓縮塵埃，使用者可容易地排出蓄積之塵埃，再者 ，可抑制吸引力的降低之電氣吸塵器。 又或，本發明之目的，爲提供一種不用加大寬幅而將 集塵裝置的軸方向的長度縮短之小巧的電氣吸塵器。 又或，本發明之目的，爲提供一種提昇了第2集塵部 的裝卸性之電氣吸塵器。 又或，本發明之目的，爲提供一種提昇了集麈裝置的 氣密性之電氣吸塵器。 又或，本發明之目的，爲提供一種使用者易於將蓄積 於通氣構件內的塵埃排出之電氣吸塵器。 又或，本發明之目的，爲提供一種不用將集塵部的前 後方向作長，即可提昇將集塵部安裝於外殼的機構之強度 ，或是抑制外殼的彎曲變形之電氣吸塵器。 又或，本發明之目的，爲提供一種可充分確保內筒之 第2集塵部側的端部與外筒之氣密性，減低空氣的能量損 失或是減低噪音之電氣吸塵器。 又或，本發明之目的，爲提供一種可充分確保內筒的 -13- 201103484 本體吸氣口側之端部與外筒的氣密性，減低空氣的能量損 失或是減低噪音之電氣吸塵器。 又或，本發明之目的，爲提供一種將內筒裝著於外筒 內時容易進行外筒與內筒之相對性的定位，容易將內筒裝 著於外筒內之電氣吸塵器。 又或，本發明之目的，爲提供一種可抑制蓄積於第2 集塵部內的塵埃朝向第1集塵部側逆流，或散落之電氣吸 塵器。 又或，本發明之目的，爲提供一種可抑制塵埃堵塞第 1集塵部與第2集塵部連通的流路之電氣吸塵器。 又或，於本發明，係以提供一種可去除細密的塵埃， 其壓力損失較小之電氣吸塵器爲目的。 〔解決問題之技術手段〕 本發明之電氣吸塵器，具備有：吸塵器本體及集塵裝 置；該吸塵器本體爲具備有電動送風機，該集塵裝置爲可 自由裝卸於吸塵器本體，其特徵爲··集塵裝置，爲具備有

塵器本體1、及集塵裝置2;該吸塵器本體1爲具備有本體 吸氣口 21及產生吸引力之電動送風機28，該集塵裝置2爲 可自由裝卸於吸塵器本體的本體吸氣口 21與電動送風機28 之間，其特徵爲：集塵裝置2，爲具備有大致圓筒形狀且 可連通於本體吸氣口 21的第1集塵部（例如：塵埃分離部4 )、以及連通於第1集塵部的軸方向端部且連通於電動送 風機2 8的第2集塵部（例如：麈埃容納部5 )，第1集塵部

於第1圖，爲顯示從側面觀察本發明之實施例的吸塵 器本體1之斷面圖。於電氣吸塵器之使用狀態，吸塵器本 體]爲橫放，於電氣吸塵器之收納狀態，則以吸塵器本體1 爲立放較理想。於電氣吸塵器之使用狀態，將本體吸氣口 2 1側作爲前方（上游側），將本體排氣口 3 0側作爲後方（ 下游側）時，則於電氣吸塵器之收納狀態，本體吸氣口 2 1 成爲重力作用方向上側而本體排氣口 30成爲重力作用方下 側方向。吸塵器本體1被橫放之場合，爲吸塵器本體1的下 表面，會與吸塵器本體i被放置之面（例如：地板面）平 行，而與重力作用方向垂直。 首先，說明吸塵器本體1的構造。從吸入之空氣捕集 塵埃之集塵裝置2，爲可自由裝卸於吸塵器本體1的前側地 配置。將集塵裝置2的長邊方向（軸方向）作爲重力作用 方向（縱型配置）時，則吸塵器本體1的高度會變較高。 另一方面’集塵裝置2內之迴旋流的軸方向（集塵裝置2的 軸方向）越接近重力作用方向，則由離心分離作用所產生 之分離效果會變越大，集塵裝置2內的迴旋流的軸方向相 對於重力作用方向，若超過45度則由離心分離作用所產生 之分離效果會極端降低。在此，爲了抑制將吸塵器本體1 的高度縮小時伴隨之由離心分離作用所產生之分離效果的 降低’於本實施例，集塵裝置2的軸方向，爲相對於重力 作用方向作成4〇度〜45度左右。不過，要提高由離心分離 -31 - 201103484 作用所產生之分離效果，集塵裝置2的軸方向，亦可作成 相對於重力作用方向比40度還小（例如：0度）。將塵埃 分離部（迴旋部）4配置於下側，代替塵埃容納部5配置於 上側，亦可將塵埃分離部4配置於上側，將塵埃容納部5配 置於下側。於場合，入口管3，以接續於塵埃分離部4的軸 方向之前側端部的圓周面爲佳。 集塵裝竄2，爲具備有使吸入之空氣迴旋，.並藉由離 心分離作用（旋風式）將塵埃分離之塵埃分離部4，以及 連通於塵埃分離部4，並容納被塵埃分離部4分離的塵埃之 塵埃容納部5。塵埃分離部4及塵埃容納部5，爲朝向集塵 裝置2的軸方向排列，並在各別之軸方向端部接續、連通 。亦即’塵埃分離部4，爲配置於吸塵器本體1的前側，塵 埃容納部5，爲相對於塵埃分離部4配置於吸塵器本體1的 前側。以使用者可容易地將塵埃分離部4及塵埃容納部5分 離之方式’將塵埃分離部4及塵埃容納部5連結一起。於吸 塵器本體1的前端，具備有管狀的本體吸氣口 21。塵埃分 離部4的軸方向之前側端面的一部分，爲呈開口，該開口 部爲被接續於入口管3。在此，也可以不是使塵埃分離部4 的軸方向之前側端面接連於入口管3，而是使塵埃分離部4 之軸方向之前側端部的圓周面接連於入口管3。入口管3, 以形成於吸塵器本體1的寬幅方向的中央爲佳。內筒7及凹 陷部8 ’亦以形成於吸塵器本體〗的寬幅方向的中央爲佳。 塵埃分離部4，爲具備有中空之大致圓筒形狀的外筒6 ’以及與外筒6爲同心軸且被內包於外筒6的中空之大致圓 ⑧ -32- 201103484 筒形狀的內筒7。爲了抑制由於迴旋流的軸心因重力引起 朝向重力作用方向的偏離使得由離心分離作用所產生之分 離效果降低，而於塵埃分離部4的軸方向相對於重力作用 方向呈傾斜之場合，亦可使內筒7的軸心相對於外筒6的軸 心朝向下側偏離。如第3圖（A )所示，外筒6的軸方向一 端面（前側端面），除了接續於入口管3的開口以外爲被 封閉，外筒6的軸方向另一端面（後側端面）’爲呈開口 。外筒6，係爲了使用者看得到塵埃蓄積或是可察覺出設 置於外筒6外的感應器的塵埃蓄積，以由透明或半透明的 塑膠或樹脂構成爲佳。內筒7的軸方向一端面（前側端面 )爲被封閉，內筒7的軸方向另一端面（後側端面），爲 呈開口。如第3圖（A)所示，於內筒7的軸方向一端面之 封閉部分的中央，形成有朝向內筒7的軸方向內側凹陷的 凹陷部8。入口管3，爲與內筒7之軸方向一端面的封閉部 分，亦即凹陷部8相向。如第3圖（A )所示，凹陷部8之一 部分，爲達至內筒7的外周端爲止。爲了減低空氣的壓力 損失，凹陷部8的開口方向，以朝向下側爲佳。不過，凹 陷部8的開口方向，亦可爲上方向或橫向方向。如第3圖（ A )所示，於凹陷部8之內筒7的外周端部，凹陷部8並非筆 直朝向內筒7的半徑方向，而是稍微朝向圓周方向傾斜。 如第1圖所示，凹陷部8的軸方向的深度，爲內筒7之圓筒 部分的軸方向之長度的大致一半左右。不過，凹陷部8的 軸方向的深度’亦可爲跨及於內筒7之圓筒部分的軸方向 之大致全長。於該場合，會變得凹陷部8的開口跨及於內 -33- 201103484 筒7之圓筒部分的大致全長地形成於內筒7的圓周面的一部 分。再者，於凹陷部8的外周端部，接續有引導管38。引 導管38的斷面爲大致1/2圓形形狀，且沿著內筒7的外周面 形成，內筒7的外周面亦形成流路之內壁面的一部分。引 導管38爲於內筒7的外周面，於圓周方向形成數cm左右。 因此，從入口管3朝向軸方向流入之空氣，爲藉由凹陷部8 而改朝向半徑方向，再者，於凹陷部8之內筒7的外周端部 處稍改朝向圓周方向，再於引導管3 8處改朝向圓周方向。 又，凹陷部8爲並非凹凸，而是以由曲面形成爲佳。藉此 ，可持續抑制壓力損失而使空氣充分地迴旋。引導管38, 即使沒有也沒關係。於內筒7之軸方向另一端面（後側端 面）的外周，形成有朝向外筒6延伸的外延部34。亦即， 如第3圖（A )所示，內筒7的軸方向另一端面（後側端面 )，成爲內筒7的內側開口之圓環狀。 如第3圖（A )所示，外延部34的圓周方向的一部分， 爲呈開口。藉由該開口，內筒7外的空氣，可流入塵埃容 納部5。內筒7，爲了能抑制菌的繁殖，以由含有抗菌作用 的金屬（例如：銀、銅）或抗菌物質（例如：銀、銅）、 或是由塗佈有上述物質的金屬（例如：不鏽鋼）所構成爲 佳。。不過，內筒7，包含圓筒部分亦可由樹脂所構成。 而，如第3圖（A)所示，藉由內筒7從外筒6的軸方向另一 端面朝向軸方向插入，使會抵接於外延部3 4的外周端外筒 6的內周，其結果，外筒6的軸方向另一端面被封閉。使外 筒6與內筒7以可以讓使用者容易地分離外筒6與內筒7之方 201103484 式來連結。於內筒7的圓周面，具備有複數個貫通孔33。 藉由複數個貫通孔33’使內筒7具備有過濾器功能。藉由 該貫通孔33，較粗大垃圾不會朝向流入內筒7內，空氣可 從內筒7外側朝向內筒7內側流入。亦因吸入力不同而有異 ’不過1日元硬幣以上的重的垃圾，不能從外筒6內吸起來 ，會有殘留於外筒6內之情形。藉由使外筒6與內筒7以可 以讓使用者容易地分離外筒6與內筒7之方式來連結者，使 得使用者，可容易地分離外筒6與內筒7，可容易地排出蓄 積於外筒6內之垃圾，又，可容易地除去卡在內筒7的貫通 孔33的頭髮或棉絮。 爲了保持塵埃分離部4與塵埃容納部5的接續部之氣密 性，與內筒7的軸方向另一端面，具備有墊片9。墊片9, 不僅只設置於外延部34，亦朝向內筒7的軸方向突出。因 此，內筒7的內側，並非完全中空，藉由墊片9而存在有一 部分封閉空間。再者，於墊片9之朝向內筒7的內側突出之 部分，形成有朝向內筒7的軸方向內側凹陷之凹陷部3 9。 凹陷部39爲具備有把手的功能。藉此，使用者將手指插入 凹陷部39，可手持塵埃分離部4或內筒7。外延部34的上側 的一部分，爲呈開口，並連通於前蓋1 1的外側流路3 5。亦 即，其爲外筒6的內側且爲內筒7的圓筒部分之外側，爲連 通於前蓋11的外側流路35。如第3圖（A)所示，外延部34 之上側的一部分的開口之圓周方向的壁面，以於圓周方向 之與引導管3 8的開口相向之側的壁面較高，於圓周方向之 引導管3 8的開口側的壁面較低爲佳。例如，從前方觀察塵 -35- 201103484 埃分離部4時’若將引導管38的開口方向作爲逆時針方向 ，則外延部3 4之上側的一部分的開口之圓周方向的壁面中 之左側的壁面爲較高’右側的壁面爲較低。亦即’由於外 延部34的上側的—部分爲呈開口’故外延部34的圓周方向 ，不滿內筒7的外周的—周分’而以螺旋狀錯開。因此’ 內筒7外的迴旋流’會碰撞外延部34之上側的一部分之開 口的圓周方向之較高的壁面’可平順地改向朝軸方向’含 於迴旋流的塵埃也變得易於朝向塵埃容納部5流動。另一 方面，內筒7的內側’爲連通於前蓋1 1的內側流路36。 塵埃容納部5，爲具備有其軸方向一端面（前側端面

8會朝向前側滑動（亦可朝向上側轉動） ⑧ -36- 201103484 ，而傳達棒18的另一端的卡爪與前蓋11的上端部的卡爪的 卡合會被解除，可藉由重力從外殻1 〇將前蓋11打開。相對 於把手16的形成方向爲水平，外殼10的軸方向一端面（相 當於前蓋11部分）的法線方向，是相對於水平方向呈傾斜 4 5度〜5 0度。亦即，使用者握住把手1 6將塵埃容納部5提 起時，外殼1〇的軸方向一端面（相當於前蓋11部分），會 朝向下側方向（重力作用方向）。因此，可藉由重力從外 殻10將前蓋11打開。又，於後有述，集塵盒（集塵容器） 1 2，爲藉由彈簧（彈性體）以朝向外殼1 0的前側彈出之方 式被彈推，由於集塵盒12按壓前蓋11的後面，所以當使用 者按下按鈕17，也可以藉由集塵盒12的按壓力平順地從外 殼10將前蓋11打開。換言之，藉由集塵盒12的開口面受到 前蓋1 1的後面的按壓，集塵盒12被收納於外殼10內，並維 持該收納狀態。 外殼10的軸方向另一端面，爲藉由可開閉之過濾器15 被封閉。於過濾器15的下端部爲具備有軸32，軸32爲藉由 外殼10的下端部被支撐。過濾器15，係以軸32爲支點而可 朝向外殼10的軸方向前後旋動。過濾器I5，爲於斷面形狀 呈大致四角形的框體內形成有被折成褶狀的過濾器構件79 。如第4圖（B)所示，過濾器構件79的波折方向以縱向方

沒有抵接於外殼10之軸方向一端面的內周面。於集塵盒12 的下部具備有軸14。軸14，爲被支撐於外殼10內。因此’ 集塵盒12以下部的軸14爲支點而可朝向外殻10的軸方向前 後旋動。藉此，從塵埃容納部5將前蓋1 1開時，藉由重力 集塵盒12的一部分可從塵埃容納部5彈出。相對於外殼1〇 之軸14的形成位置，由於爲與相對於外殼10之軸31的形成 位置相同側（下側），故從塵埃容納部5將前蓋1 1開時， 不會有因前蓋11造成妨礙之情形，集塵盒12的一部分可從 塵埃容納部5彈出。再者，於軸1 4，亦可具備有在將集塵 盒1 2朝向前蓋1 1側推出之方向作用彈性力之螺旋彈簧。藉 此，從塵埃容納部5將前蓋1 1開時，藉由彈簧的彈性力， 集塵盒12的一部分可從塵埃容納部5強勁彈出，使用者可 容易地排出蓄積於集塵盒12內之塵埃。再者，集塵盒12， 被分割成上下，亦即以由上半部的框體（支架）及下半部 的框體（支架）之所謂2個構造物所構成較佳。被分割成2 個之集塵盒12，係藉由形成於集塵盒12的底面之外側的軸 13而連結一起。因此’如第4圖（Α)所示，集塵盒12，係 以底面的中間爲支點，集塵盒1 2的開口面被分割成上下。 特別是集塵盒12的一部分從塵埃容納部5彈出之時，集塵 -39- 201103484 盒1 2被分割成上下。藉此’使用者可更容易地排出蓄積於 集塵盒12內之塵埃。特別是緊貼於集塵盒12之內面的塵埃 也可容易地刮落。不過，集塵盒12之分割成上下2個的構 成，並非必須。由於除了外殻1 〇的前側爲相對於重力作用 方向傾斜40°〜45°之外再加上’集塵盒12從塵埃容納部5傾 斜30°彈出，所以可使蓄積於集塵盒12內之塵埃朝向大致 重力方向排出。 於前蓋1 1內，形成有朝軸方向貫通之外側流路3 5及內 側流路3 6。而，外側流路3 5，爲形成於前蓋1 1的上側，外 側流路3 5的一端爲連通於相當於塵埃分離部4之特別是外 筒6與內筒7的筒部之間的外延部34之開口，外側流路35的 另一端爲連通於外殻1〇之特別是集塵盒12的開口。於電氣 吸塵器停止時，爲了防止蓄積於集塵盒12之塵埃逆流於外 側流路3 5及塵埃分離部4，外側流路3 5的另一端以連通於 比集塵盒12的開口中的一半更上側或上端附近爲佳。不過 ，外側流路3

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an electric vacuum cleaner, and more particularly to a cyclone type electric vacuum cleaner. [Prior Art] As described in the prior art, the dust storage chamber is disposed on the lower side of the dust separation chamber, and the dust-containing air outside the suction cylinder in the dust separation chamber flows into the dust storage chamber and is removed in the dust storage chamber. After the coarse sand waste of a large mass, the first filter at the lower end of the suction cylinder is sucked from the lower end of the suction cylinder and passed through the suction cylinder, and the second vacuum cleaner is absorbed by the electric blower. . Furthermore, it is described that an outer cylinder is provided on the concentric circle of the suction cylinder, and a compression plate is provided at the lower end thereof, and if the outer cylinder and the compression plate are lowered together, the dust accumulated in the dust accommodation chamber is compressed by the compression plate. The bristles provided on the inner peripheral surface of the outer cylinder scrape off the dust adhering to the filter formed in the suction cylinder. Patent Document 2 discloses that a separation chamber and a dust accommodation portion are arranged in parallel in the dust collecting case, and air outside the inner cylinder of the separation chamber flows into the dust accommodation portion from the separation chamber, and merges with the air in the inner cylinder of the separation chamber, and The mesh-like mesh filter and the pleated filter are adsorbed to the electric vacuum cleaner of the electric blower. Further, when the dust accumulated in the mesh-shaped mesh filter and compressed by the suction is discarded, the mesh-shaped mesh filter and the pleated filter are pivoted and opened at the lower end. Patent Document 3 discloses that a dust receptacle which is provided inside the dust collecting case for collecting 201103484 dust collects dust when the dust accumulating in the dust container is compressed by suction, and the dust receptacle is at the lower end. The shaft is ejected from the dust collecting housing on one side and disintegrated into an upper and lower electric vacuum cleaner. Patent Document 4' describes that a side of a cylindrical swirler body is formed with a suction port for sucking dirty air in the axial direction, and the other side is formed with air for discharging the purified air toward the axial direction. The discharge port is provided with a turning force imparting means for rotating the air in the direction of the suction shaft in the wiring direction inside the swirler body, and on the discharge port side, the dirt separated by the centrifugal force is provided toward the wiring direction. The guided dirt discharge port 'end end of the dirt discharge port is a downstream wind cyclone dust collecting device that is detachably provided with a dust box. Patent Document 5 describes an electric vacuum cleaner including a cyclone collector. The cyclone is disposed so as to extend in a horizontal direction so that the rotary shaft of the swirling flow generated inside the cyclone portion extends substantially horizontally. Further, in Patent Document 5', it is described that a dust-containing air from the floor suction port becomes a swirling flow when passing through a half-circumferential flow path of the cover from the suction port of the cyclone, and the intervening opening is introduced into the cyclone portion, and then along the edge. The inner peripheral wall of the cyclone dust collector is separated from the air by the umbrella-shaped partition plate of the middle cylinder, and is collected by the dust collecting portion, and is purified by the aforementioned swirling flow. The air is first purified by the mesh filter, and then passes through the inside of the middle cylinder, and the air that enters the dust collector together with the dust is passed through the mesh filter for the first time. The dust inside the dust collecting portion is compressed, and the air purified by the mesh filter for the first time reaches the filter for the second time, and then passes through the air inside and outside the middle cylinder, and is filtered twice by the filter-6- 201103484 After filtering, it reaches the electric blower. Patent Document 6 discloses a dust container for an electric vacuum cleaner which is formed by combining a casing of a so-called casing and an inner casing to form a swirling flow path, a connecting flow path, and a dust collecting space. Further, Patent Document 6' describes that the inner casing includes a buffer space for receiving air entering from the intake port, a swirling flow path forming portion that induces air in the buffer space in a clockwise direction, and a swirling flow path. a semi-columnar convex portion that protrudes inward in the forward direction of the forming portion, and a peripheral hole that is penetrated in the swirling direction on the circumferential surface of the semi-columnar convex portion is provided with a plurality of small holes for ventilation that are penetrated. The air and dust mites entering the buffer space mainly flow along the swirling flow path forming portion toward the right side toward the downstream side, and swirl around the convex portion, and a part of the swirling air is formed through the convex portion. Most of the ventilation holes are used and flow toward the back side. Further, in Patent Document 6 and Patent Document 9, it is described that by collecting a dust collecting space around the downstream side of the swirling flow path, dust is accumulated from the outside of the dust collecting space, and on the other hand, by the swirling flow path. The downstream side is provided with a guide surface having a smooth bulging of the inner casing, so that the dust mites hardly adhere to the guide surface, and even if a lot of dust is accumulated around the dust collecting space, air swirling can be performed in the swirling flow path. Therefore, even if a lot of dust is accumulated in the dust collecting space, the air flow of the swirling flow path itself is not hindered, the air is swirled, and the attraction force is hardly lowered. Patent Document 7 discloses that when the dust collecting case is housed in the cleaner body, the elastic sealing portion is not provided in the vertical direction, but the upper side is inclined to the side of the electric blower, and therefore, the dust collecting case is provided. Body 201103484 It is easy to obtain airtightness when it is pressed into the body of the cleaner, and it is easy to load and unload the electric vacuum cleaner of the cyclone dust collecting part of the dust collecting body from the cleaner body. Further, in Patent Document 7, it is described that when the cyclone separation drum and the dust collecting case are integrally formed and attached to the cleaner body, the ease of removal is considered, and the front-rear direction of the upper portion is longer than the length in the front-rear direction of the lower portion. The way to set the draft angle. Correspondingly, the filter housing is also disposed obliquely with respect to the floor surface, so that the lower side of the filter housing is longer than the upper side. Patent Document 8 also discloses a dust collecting device storage chamber which is formed to be inclined toward the front side as the front side wall surface is inclined upward, and the rear side wall surface is formed substantially vertically, and the dust collecting device storage chamber becomes more and more as it goes upward. It is formed in a wide area, and when the dust collecting device is housed, an electric vacuum cleaner that can guide the dust collecting device to be smoothly stored can be guided. In the related art, in the non-patent document, when the cleaner body is placed in the same direction as in the case of the general cleaning, the axis of the substantially cylindrical dust cup is placed obliquely on the front of the cleaner body, the motor and the wire reel. In order to be disposed adjacent to the rear of the cleaner body, an anti-allergy HEP A clean filter is disposed on the upper portion of the dust cup body and on the upper portion of the cleaner body, substantially at the center of the cleaner body, before the motor, next to the wire reel, and downstream of the motor.

Html [Summary of the Invention] [Technical Problem to be Solved by the Invention] In Patent Document 1, In order to compress the dust to accommodate the dust inside the room, The user has to operate the compression plate by operating the lever, Therefore, the burden on the user is large. here, Instead of the first filter of Patent Document 1, The dust container of Patent Document 3 is considered to be opened to the upper side, However, in Patent Document 1, Since the air flowing into the dust receiving chamber is sucked from the opening of the lower end of the suction cylinder, Therefore, the dust accumulated in the container of the patent document 3 is Also inhaled from the underside of the inhaler together with the air. the result, Toward the electric air supply -9 - 201103484 The amount of dust accumulated in the first filter in front of the machine increases. The attraction is reduced. In Patent Document 2, Since the separation chamber is arranged side by side with the dust receiving portion, Therefore, it is impossible to enlarge the diameter of the separation chamber and its inner cylinder. Therefore, the degree of inhalation of the inner cylinder from the separation chamber is increased as the dust accumulates in the dust accommodation portion. And the pressure loss of the inhalation becomes large, the result, Compared to the initial state without accumulated dust, The attraction is reduced. also, In Patent Document 2, Since the mesh mesh filter is flat, Therefore, there is a possibility that the user cannot easily remove the dust adhering to the mesh-shaped mesh filter. Instead of the mesh-shaped mesh filter of Patent Document 2, Considering the dust container of Patent Document 3, However, the enamel container of Patent Document 3 is in the shape of a container. Therefore, the shape of the rear portion of the dust collecting casing becomes large. also, When the user holds the handle of Patent Document 2 to open the rear of the dust collecting case, Due to the ejection direction of the dust container of Patent Document 3, For the user, the close (handle) side, Therefore, the dust in the dust container is caught in the rear portion of the dust containing portion of Patent Document 2 and cannot be smoothly discharged. Furthermore, The ejected dust container itself collides with the rear of the dust receiving portion and the dust container itself cannot be ejected smoothly. also, In Patent Document 3, Even if the dust container is ejected from the dust collecting case, The rear part of the dust container is also in contact with the dust collecting casing. Therefore, the direction in which the opening portion of the front side of the dust container is ejected, Compared to the horizontal direction, it is closer to the vertical direction. There is dust remaining in the dust container. Again, user, In order to make the opening of the front side of the dust container face the lower direction -10- 201103484 , To turn the grip toward the lower side, you must turn your wrist. And the burden of users has become bigger. also, In Patent Document 3, Since the rotating shaft of the dust collecting container is directly formed on the inner lower surface of the dust collecting casing, Therefore, there will be insufficient strength. Or the lower surface of the dust collecting casing is bent, And damage the appearance. In Patent Document 4, Because in order to generate cyclone flow, And the necessary turning force is given, Therefore, the length of the cyclone dust collecting device will become longer in the axial direction. the result, There is a possibility that the length of the front and rear of the vacuum cleaner body becomes long. E.g, When the dust box is disposed adjacent to the axial direction with respect to the cyclone body, The length of the axial direction of the cyclone dust collector will become longer. the result, The length of the vacuum cleaner body in the front-rear direction also becomes longer. also, In Patent Document 4, After the flow path is reduced from the contaminated air suction port and the flow rate is lowered, Will impart a polluted air turning force, Therefore, the turning speed is slow, And the centrifugal force is reduced, There will be a flaw in the separation of polluted air. also, In Patent Document 4, Since the tube from the turning force imparting means to the discharge port is long, The air swirls from the turning force imparting means to the barrel of the discharge port. Therefore, the energy loss of air is large. also, There are also noise noises. also, In Patent Document 4', since the turning force imparting means is formed by a plurality of fins (heat sinks), the energy loss of the air is large, also, There are also noise noises. also, In Patent Document 4, Since the exhaust port from the dust box to the outside is not provided, the exhaust gas discharged from the cyclone body is only the exhaust port corresponding to the small diameter of the inner cylinder, so the energy loss of the exhaust air is large. also, In Patent Document 4, Since there is no means for compressing the dust accumulated in the dust box, Therefore, the dust collection capacity of the dust box is small. In Patent Document 5, Due to the inside of the cover placed on the front side of the front end of the middle cylinder -11 - 201103484, Forming a flow path for generating a swirling flow, Therefore, the length of the cyclone (in the axial direction) of the cyclone will become longer. the result, The length of the front and rear direction of the vacuum cleaner body becomes longer. also, Since the middle cylinder is formed, the shape of the partial mesh filter is a triangular cone. Therefore, as it goes closer to the downstream side in the horizontal direction (axial direction) (as it goes closer to the bottom from the top of the triangular pyramid), The easier the dust is attached to the surface of the primary mesh filter, And the attractive reduction is described in Patent Document 6, Due to the outer side in the radial direction of the semi-cylindrical convex portion, Forming a buffer space and a swirling flow path forming portion, Therefore, the length of the dust chamber (up, down, left, and right) becomes longer. the result, There is a possibility that the height and the lateral width of the front portion of the cleaner body become larger. In Patent Document 7 and Patent Document 8, There is no description of the sealing mechanism between the cyclone separation cylinder and the casing. therefore, The direction in which the elastic sealing portion is formed with respect to the exhaust side opening of the dust collecting housing (non-vertical direction, The upper side is inclined to the side of the electric blower) Where the joint surface of the cyclone separation drum and the dust collecting casing is largely inclined, Only the sealing member is interposed between the cyclone separation drum and the dust collecting casing. There will be a situation where you can't get enough airtightness. Exhaust HEP A clean filter described in the non-patent literature, In order to remove the fine dust inside the body which cannot be completely removed by the HEP A cleansing filter, The exhaust of the HEP A clean filter through the exhaust can be made cleaner. But although it can remove fine dust, However, there is a greater pressure loss. In order to reduce the pressure loss, The area of the filter must be increased. However, the exhaust HEPA clean filter recorded in the non-patent literature is installed next to the electric reel 8-12-201103484. Therefore, in addition to widening the width of the vacuum cleaner body, To increase the area of the filter, It is difficult to construct. also, The exhaust HEPA clean filter described in the non-patent literature is not fixed. For loading and unloading. therefore, When the exhaust HEP A clean filter is attached to the cleaner body, There is a slight gap between the motor and the exhaust HEPA clean filter. There will be no way to remove fine dust. here, The purpose of the present invention, To provide a kind of dust that can be compressed without the need of annoying users, The user can easily discharge the accumulated dust. Again, An electric vacuum cleaner that suppresses the decrease in attractiveness.

Further, a guide tube 38 is connected to the outer peripheral end portion of the recessed portion 8. The guide duct 38 has a substantially 1/2 circular cross section and is formed along the outer peripheral surface of the inner cylinder 7, and the outer peripheral surface of the inner cylinder 7 also forms a part of the inner wall surface of the flow path. The guide duct 38 is formed on the outer peripheral surface of the inner cylinder 7, and is formed in the circumferential direction by several cm. Therefore, the air that flows in from the inlet pipe 3 toward the axial direction is redirected toward the radial direction by the recessed portion 8, and further, the outer peripheral end portion of the inner cylinder 7 of the recessed portion 8 is slightly changed toward the circumferential direction, and then guided. The tube 38 is changed toward the circumferential direction. Further, the depressed portion 8 is preferably formed not by the unevenness but by the curved surface. Thereby, the pressure loss is continuously suppressed and the air is sufficiently swirled. Guide tube 38, even if it is not okay. An extension portion 34 that extends toward the outer cylinder 6 is formed on the outer circumference of the other end surface (rear end surface) in the axial direction of the inner cylinder 7. That is, as shown in Fig. 3(A), the other end surface (rear end surface) of the inner cylinder 7 in the axial direction is an annular shape that opens inside the inner cylinder 7. As shown in Fig. 3(A), a part of the circumferential direction of the extension portion 34 is an opening. By this opening, the air outside the inner cylinder 7 can flow into the dust containing portion 5. The inner cylinder 7 is made of a metal containing an antibacterial action (for example, silver or copper) or an antibacterial substance (for example, silver or copper) or a metal coated with the above substance (for example, stainless steel) in order to inhibit the growth of bacteria. ) is better. . However, the inner cylinder 7, which comprises the cylindrical portion, may also be composed of a resin. As shown in Fig. 3(A), the inner cylinder 7 is inserted from the other end surface of the outer cylinder 6 in the axial direction toward the axial direction, and is brought into contact with the inner periphery of the outer peripheral end outer cylinder 6 of the extension portion 34. As a result, the other end surface of the outer cylinder 6 in the axial direction is closed. The outer tube 6 and the inner tube 7 are connected in a manner that allows the user to easily separate the outer tube 6 from the inner tube 7. A plurality of through holes 33 are provided in the circumferential surface of the inner cylinder 7. The inner cylinder 7 is provided with a filter function by a plurality of through holes 33'. With the through hole 33, the coarser garbage does not flow into the inner cylinder 7, and the air can flow from the outer side of the inner cylinder 7 toward the inner side of the inner cylinder 7. It is also different depending on the inhalation force. However, the heavy garbage of one yen or more of the coin cannot be sucked up from the outer tube 6, and may remain in the outer tube 6. By connecting the outer cylinder 6 and the inner cylinder 7 so that the user can easily separate the outer cylinder 6 from the inner cylinder 7, the user can easily separate the outer cylinder 6 and the inner cylinder 7, which can be easily The garbage accumulated in the outer tube 6 is discharged, and the hair or the batt which is caught in the through hole 33 of the inner tube 7 can be easily removed. In order to maintain the airtightness of the joint portion of the dust separating portion 4 and the dust containing portion 5, the gasket 9 is provided on the other end surface of the inner cylinder 7 in the axial direction. The spacer 9 is provided not only on the extension portion 34 but also in the axial direction of the inner cylinder 7. Therefore, the inner side of the inner cylinder 7 is not completely hollow, and there is a part of the closed space by the gasket 9. Further, a recessed portion 39 which is recessed toward the inner side in the axial direction of the inner cylinder 7 is formed in a portion of the spacer 9 which protrudes toward the inner side of the inner cylinder 7. The recessed portion 39 has a function of having a handle. Thereby, the user inserts a finger into the recessed portion 39, and the dust separating portion 4 or the inner cylinder 7 can be held. A part of the upper side of the extension portion 34 is open and communicates with the outer flow path 35 of the front cover 11. That is, it is the inner side of the outer cylinder 6, and is the outer side of the cylindrical portion of the inner cylinder 7, and is an outer flow path 35 that communicates with the front cover 11. As shown in Fig. 3(A), the wall surface in the circumferential direction of a part of the opening on the upper side of the extension portion 34 is higher in the circumferential direction on the side opposite to the opening of the guide tube 38, and is guided in the circumferential direction. The wall surface on the open side of the tube 38 is preferably lower. For example, when the dust-35-201103484 angstrom separation portion 4 is viewed from the front, when the opening direction of the guide tube 38 is counterclockwise, the wall surface on the left side in the circumferential direction of a part of the opening on the upper side of the extension portion 34 is formed. The wall for the higher 'right side is lower. That is, since the upper portion of the outer portion 34 is an opening, the circumferential direction of the extension portion 34 is less than the circumference of the outer circumference of the inner cylinder 7, and is spirally shifted. Therefore, the 'swirl flow outside the inner cylinder 7' will hit the upper wall surface of the opening on the upper side of the extension portion 34, and the higher wall surface in the circumferential direction can be smoothly changed toward the axial direction. The dust contained in the swirling flow also becomes easy to face. The dust accommodation portion 5 flows. On the other hand, the inner side of the inner cylinder 7 is the inner flow path 36 that communicates with the front cover 11. The dust accommodating portion 5 is provided with a casing 10 having a one end surface (front end surface) in the axial direction and the other end surface (rear end surface) in the axial direction opening and having a substantially inverted triangular shape in cross section. An end face of the outer casing 10 in the axial direction is closed by the cover 11 before being opened and closed. A shaft 31 is provided at a lower end portion of the front cover 11, and the shaft 31 is supported by a lower end portion of the outer casing 10. The front cover 11 is pivotable forward and backward in the axial direction of the casing 10 with the shaft 31 as a fulcrum. On the side of the outer casing 1 at the upper end portion of the front cover 11, there are claws protruding. On the other hand, on the front upper portion of the casing 10, there is provided a button 17 (which may be a control lever) that the user can press, and a button (bar) extending toward the front side of the casing 10 is connected to the button 17. 1 8. One end of the transmission rod 18 is connected to the button 17 and the other end of the transmission rod 18 is formed as a claw. The claw at the other end of the rod 18 is conveyed to the claw that can be engaged with the upper end portion of the front cover 11. In a state where the outer casing 10 is closed with the front cover 11, the claw of the other end of the conveying rod 18 is engaged with the claw of the upper end portion of the front cover 11, and the front cover 11 can be prevented from being opened. Then, if the user presses the button 17 7 , the communication bar 18 slides toward the front side (also can be rotated toward the upper side) 8 -36 - 201103484 , and the claw of the other end of the bar 18 and the upper end of the front cover 11 are transmitted. The engagement of the claws is released, and the front cover 11 can be opened from the outer casing 1 by gravity. The direction in which the handle 16 is formed is horizontal, and the normal direction of the one end surface of the outer casing 10 (corresponding to the portion of the front cover 11) is inclined by 45 to 50 degrees with respect to the horizontal direction. That is, when the user holds the handle 16 to lift the dust containing portion 5, the one end surface of the outer casing 1 in the axial direction (corresponding to the portion of the front cover 11) faces in the lower direction (the direction of gravity action). Therefore, the front cover 11 can be opened from the outer casing 10 by gravity. Further, as will be described later, the dust collecting box (dust collecting container) 12 is pushed by the spring (elastic body) toward the front side of the outer casing 10, and the dust collecting box 12 presses the front cover 11 Later, when the user presses the button 17, the front cover 11 can be smoothly opened from the outer casing 10 by the pressing force of the dust box 12. In other words, the dust collecting case 12 is housed in the casing 10 by the opening of the front cover 1 by the opening surface of the dust collecting case 12, and the storage state is maintained. The other end surface of the outer casing 10 in the axial direction is closed by a filter 15 that can be opened and closed. The lower end portion of the filter 15 is provided with a shaft 32 which is supported by the lower end portion of the outer casing 10. The filter 15 is pivotable forward and backward in the axial direction of the casing 10 with the shaft 32 as a fulcrum. The filter I5 is formed with a filter member 79 that is folded into a pleat shape in a frame having a substantially quadrangular cross-sectional shape. As shown in Fig. 4(B), the direction of the waviness of the filter member 79 is preferably in the longitudinal direction (the direction of gravity action). The filter 15 is, for example, a High Efficiency Particulate Air Filter. The so-called HEPA filter is for the particle size of 0 at the rated air volume. The 3/zm particle has 99. More than 97% of the particle collection rate, and is an air filter with initial pressure loss -37-201103484 245Pa performance. A spacer 25 may be provided on the opposite side of the outer casing 10 of the filter 15. By the gasket 25, the airtightness of the other end surface of the dust containing portion 5 in the axial direction and the cleaner body 1 (particularly, the inlet of the suction duct 27) can be maintained. Further, the shaft 31 and the shaft 32 may be shared. Further, the shaft 32 is not provided at the lower end portion of the filter 15, and may be provided at the upper end portion of the filter 15. In the outer casing 10, the dust box 12 is wrapped. The shape of the dust box 12 may be a box shape having an open surface, a box shape or a container shape, or a bucket shape. . That is, the dust collecting case 12 has a shape that is recessed toward the side opposite to the opening. The cross-sectional shape of the dust collecting box 12 may be substantially square or may be substantially circular or substantially triangular. The cross-sectional shape of the dust collecting case 12 is preferably reduced from the opening surface toward the bottom surface. As a result, since the sectional area is expanded toward the side (opening side) where the dust is discharged, the user can easily discharge the dust accumulated in the dust collecting case 12. The shape of the dust box 12 is formed by a frame (bracket). It is preferable that the bottom surface and the upper, lower, left and right surfaces other than the opening surface of the dust collecting case 12 are covered or adhered to a mesh member made of metal or nylon. Not only the bottom surface of the dust box 12 but also the air permeability of the upper and lower sides, the dust can be stored in the bottom surface of the dust box 12, and the pressure loss of the intake air can be ensured, and the decrease in the suction force can be suppressed. . The mesh member is air permeable and has a filter function for trapping dust. The mesh member and the fiber paper may be combined as long as they are air-permeable and have a function of a furnace that collects dust, instead of the mesh member, which may be a disposable paper. For example, the user can also load fiber paper on the mesh member. The opening surface of the dust box 丨 2 is the opening surface of the one end surface (front side end surface) of the outer casing of the casing -1 - 8 - 8 201103484. That is, the opening direction of the dust collecting case 12 is the same as the opening of the outer casing 10 in the axial direction. As shown in Fig. 6, the upper half of the outer peripheral end of the opening surface of the dust collecting case 12 is the inner peripheral surface that abuts against the one end surface of the outer casing 1 in the axial direction, and the outer peripheral end of the opening face of the dust collecting case 12 The lower half of the lower side does not abut against the inner peripheral surface of one end surface of the outer casing 10 in the axial direction. A shaft 14 is provided at a lower portion of the dust box 12. The shaft 14 is supported within the outer casing 10. Therefore, the shaft 14 at the lower portion of the dust box 12 is pivoted forward and backward toward the axial direction of the casing 10. Thereby, when the front cover 1 is opened from the dust accommodating portion 5, a part of the gravity dust box 12 can be ejected from the dust accommodating portion 5. Since the position at which the shaft 14 of the outer casing 1 is formed is the same side (lower side) as the position of the shaft 31 with respect to the outer casing 10, there is no cause when the front cover 1 is opened from the dust containing portion 5. The front cover 11 causes an obstacle, and a part of the dust box 12 can be ejected from the dust receiving portion 5. Further, the shaft 14 may be provided with a coil spring that exerts an elastic force in a direction in which the dust box 12 is pushed toward the front cover 1 1 side. Thereby, when the front cover 1 is opened from the dust accommodating portion 5, a part of the dust box 12 can be strongly ejected from the dust accommodating portion 5 by the elastic force of the spring, and the user can easily discharge the accumulated dust collecting case 12 The dust inside. Further, the dust collecting case 12 is preferably divided into upper and lower sides, that is, the so-called two structures of the frame (bracket) of the upper half and the frame (bracket) of the lower half. The dust box 12 divided into two is joined together by a shaft 13 formed on the outer side of the bottom surface of the dust box 12. Therefore, as shown in Fig. 4 (Α), the dust collecting box 12 is fulcrum with the middle of the bottom surface, and the opening surface of the dust collecting box 12 is divided into upper and lower sides. In particular, when a part of the dust box 12 is ejected from the dust containing portion 5, the dust collecting-39-201103484 box 12 is divided into upper and lower sides. Thereby, the user can discharge the dust accumulated in the dust collecting case 12 more easily. In particular, dust adhering to the inner surface of the dust box 12 can be easily scraped off. However, the division of the dust box 12 into two upper and lower parts is not essential. Since the front side of the outer casing 1 is inclined by 40° to 45° with respect to the direction of gravity, the dust collecting box 12 is ejected from the dust receiving portion 5 by 30°, so that it can be accumulated in the dust collecting box 12. The dust is discharged toward the direction of gravity. In the front cover 1 1 , an outer side flow path 35 and an inner side flow path 36 are formed in the axial direction. Further, the outer flow path 35 is formed on the upper side of the front cover 1 1 , and one end of the outer flow path 35 is connected between the outer portion corresponding to the dust separation portion 4 and the outer tube 6 and the inner tube 7 . The opening of the extension portion 34 and the other end of the outer flow path 35 are openings that communicate with the outer casing 1 , particularly the dust box 12 . When the electric vacuum cleaner is stopped, in order to prevent the dust accumulated in the dust collecting case 12 from flowing back to the outer flow path 35 and the dust separating portion 4, the other end of the outer flow path 35 is communicated with half of the opening of the dust collecting case 12. It is better to be near the upper side or the upper side. However, the other end of the outer flow path 35 may also communicate with the central portion of the opening of the dust box 12. Further, when the electric vacuum cleaner is stopped, in order to prevent the dust accumulated in the dust collecting case 12 from flowing back to the inside of the outer flow path 35 and the other end portion of the outer side flow path 35 and the dust separating portion 4', the cover is formed to cover. The check valve (not shown) of the outer flow path 35 is preferred. The check valve is rotated toward the dust box 12 by the upper end being a fulcrum. However, check valves are not a mandatory component. The sectional area of the outer flow path 35 is enlarged from one end of the outer flow path 35 toward the other end. The direction in which the outer side flow path 35 is formed is from the one end of the outer side flow path 35 toward the other end and from the outer side of the front cover 11 toward the center side. That is, 'from the outer side of the dust box 1 2 (S) • 40-201103484 toward the center side. In order to suppress the disturbance of the air flowing in from the outer flow path 35 toward the dust collecting case I 2, the direction in which the outer flow path 35 is formed is the wall surface (upper side wall surface) on the side where the outer flow path 35 of the dust collecting case 1 communicates. The direction is good. The inner flow path 3 6 ' is formed from the center to the lower side of the front cover 1 1 , and one end of the inner flow path 36 is open to the other end of the inner portion of the inner portion of the inner portion of the inner portion 7) The other end of the inner flow path 36 is connected to the outer side of the outer casing 1 , particularly the dust collecting box 12 . The other end of the inner flow path 36 is preferably connected to the outer lower side of the dust box 12. The inner flow path 3 6 is formed to avoid the outer flow path 35. The cross-sectional area of the inner flow path 36 is opposite to the outer flow path 35, and is narrowed from one end of the inner flow path 36 toward the other end, and is provided on the outer side of the upper portion of the dust accommodation portion 5, and is provided by a user extending in the horizontal direction. Live the handle 1 6. The user holds the handle 16 and lifts the dust accommodation portion 5 upward, while leaving the dust separation portion 4 in the cleaner body 1, and can remove only the dust accommodation portion 5 from the cleaner body 1. When the dust separating unit 4 and the dust accommodating portion 5 are connected, the user's holding the handle 16 and lifting the dust accommodating portion 5 upward may be used as the integrated dust separating portion 4 and the dust accommodating portion 5 That is, the dust collecting device 2 is also discharged from the cleaner body 1. As shown in Fig. 1, the direction in which the other end surface of the dust receiving portion 5 in the axial direction (corresponding to the portion of the filter 15) is inclined more toward the outer casing 10 side than the vertical surface (gravity action direction). That is, it is preferable that the lower portion of the upper end portion of the other end surface in the axial direction of the dust accommodation portion 5 is closer to the side of the outer casing 1 . Further, as shown in Fig. 1, the direction of formation of the one end surface (corresponding to the portion of the front cover 11) in the axial direction of the dust accommodation portion 5 is inclined toward the outer casing 10 side than the vertical surface (gravity action direction) -41 - 201103484 40 degrees ~ 45 degrees or so. That is, the lower portion is closer to the outer casing 10 side than the upper portion of the one end surface of the dust accommodation portion 5 in the axial direction. Thereby, the one end surface in the axial direction and the other end surface in the axial direction of the dust accommodation portion 5 are inverted eight-shape based on the vertical surface (gravity action direction). Thereby, the user does not get stuck when the dust receiving portion 5 is lifted upward, and the user can easily remove the dust containing portion 5 from the cleaner body 1. When the dust accommodating portion 5 is removed, the user holds the recessed portion 3, and lifts the dust separating portion 4 upward or upward, thereby easily removing the dust separating portion 4 from the cleaner body 1. As shown in Fig. 1, the direction in which the one end surface (corresponding to the portion of the inlet pipe 3) in the axial direction of the dust separating portion 4 is inclined more toward the outer tube 6 side in the vertical plane (gravity action direction). In other words, it is preferable that the lower portion is closer to the outer tube 6 side than the upper portion of the other end surface in the axial direction of the dust separating portion 4. Thereby, the user does not get stuck when the dust separating portion 4 is lifted upward or obliquely upward, and the user can easily remove the dust separating portion 4 from the cleaner body 1. In addition, when the user separates the dust separating unit 4 from the dust collecting unit 4, the dust collecting unit 4 and the dust storing unit 5 are integrated, and the dust collecting device 2 is removed from the cleaner body 1 due to dust collection. The one end surface in the axial direction of the device 2 and the other end surface in the axial direction are inverted eight-shaped on the basis of the vertical surface (the direction of gravity action), so that the dust collecting device 2 is not lifted when it is lifted upward, and the user can easily The dust collecting device 2 is detached from the cleaner body 1. At the body suction port 21, a hose joint pipe 20 is inserted to hold the hose joint pipe 20. A spacer 22 is provided at one end of the body suction port 21. Thereby, the airtightness of the hose joint pipe 20 and the inlet pipe 3 can be maintained. The vacuum cleaner -42 - 201103484 The front lower end of the main body 1 (the lower side of the dust collecting device 2) is provided with a caster support portion 23 for supporting the casters. An intake duct 27 that extends toward the front-rear direction of the cleaner body 1 is provided on the upper rear side of the cleaner body 1. The opening of one end of the suction duct 27 in the extending direction is opposed to the filter 15. An auxiliary filter 26 is provided in the vicinity of the opening of one end of the intake duct 27. Thereby, it is possible to suppress the dust blown by the electric blower 28 from remaining outside the dust collecting device 2. The other end of the suction duct 27 in the extending direction is closed, and the suction duct 27 is extended to the lower portion near the other end, that is, the side of the electric blower 28 is open. The upper portion of the opening of one end of the intake duct 27 of the cleaner body 1 is provided at a position in contact with the filter 15 to be removed from the filter! 5 dust removal device 24. The dust removing device 24 is provided with a spiral spring (elastic body) on the outer circumference of the rotating body. The dust removing device 24 is rotated by the pulling out of the motor or the electric wire reel, and the dust adhering to the filter 15 is shaken off by the filter member 79 of the spiral spring bounce filter 15. As described above, since the direction of the waviness of the filter 15 is the longitudinal direction, the dust that is shaken off tends to fall toward the direction of gravity. The dust that has been shaken off from the filter 15 is accumulated in the casing 10. Thereby, it is possible to suppress the mesh clogging of the filter 15, suppress the decrease in the pressure loss of the air, and suppress the decrease in the suction force. An electric blower 28 that generates an attraction force is provided on the lower rear side of the cleaner body 1. The electric blower 28 is placed upright with the suction port of the electric blower 28 facing upward. The exhaust fan 40 is provided on the downstream side of the electric blower 28 and on the front side of the electric blower 28, and is provided with an exhaust duct 40 that communicates with the exhaust port of the electric blower 28. Further, on the downstream side of the exhaust duct 40 and at the front side of the exhaust duct 40, a filter 29-43-201103484 communicating with the exhaust duct 40 is provided. The filter 29 has a filter member 79 which is folded into a pleat shape in a frame 78 having a substantially quadrangular cross-sectional shape. The wave-folding direction of the filter member 79 is preferably in the longitudinal direction (the direction of gravity action). The filter 15, for example, is a high density ULPA filter (Ultra Low Penetration Air Filter). ULPA filter for particle size at nominal air volume of 0. 15 //m particles, with 99. The particle collection rate of 9995% or more is an air filter having a performance of an initial pressure loss of 245 Pa or less, and has a particle collection efficiency higher than that of the HEP A filter. Further, a body exhaust port 30 is provided at the rear end surface of the cleaner body 1. Next, the flow of air during operation (when used) of the electric vacuum cleaner will be described. The arrow in Figure 1 shows the air flow. When the user turns on the power of the electric vacuum cleaner, the electric blower 28 operates to generate an attractive force. The air sucked from the hose joint pipe 20 flows into the outer cylinder 6 through the inlet pipe 3, and collides with the recessed portion 8 to be redirected in the radial direction, and further, at the outer peripheral end of the inner cylinder 7 of the recessed portion 8 The position is slightly changed to the circumferential direction, and then the guide tube 38 is redirected toward the circumferential direction. As a result, the air is swirled around the outer cylinder 6 around the axial center of the outer cylinder 6. That is, as a swirling flow, by the centrifugal separation caused by the swirling of the air, the heavier dust contained in the air is concentrated on the outside of the swirling flow. The lighter dust contained in the air remains on the outside of the swirling flow and remains on the inside. However, in general household cleaning, most of the dust is concentrated on the outside of the swirling flow, and there is little dust remaining on the inner side of the swirling flow. The air outside the inner cylinder 7 passes through the outer flow path 35 together with the heavy dust, and flows into the dust box 12. The dust is trapped by the dust box 12 and accumulated, and then compressed by the attraction. Since the dust is automatically compressed by the attraction 8 -44 - 201103484, it can keep a lot of dust without the trouble of the user's hand. The air passes through the bottom surface and the upper, lower, left and right sides of the dust box 12, and reaches the filter 15. On the other hand, the inside air of the swirling flow flows into the inner cylinder 7 from the through hole 3 3 of the inner cylinder 7. The dust larger than the through hole 3 3 cannot pass through the through hole 33 and remains outside the inner cylinder 7. The air in the inner cylinder 7 passes through the inner flow path 36 together with the lighter dust of the dusty dust, and flows into the lower side of the outer casing 10 toward the lower portion of the dust collecting case 12 to reach the filter 15. The air passing through the dust collecting box 1 2 and the air that has not passed through the dust collecting box I2 merge at the |ij surface of the furnace 15 and pass through the filter 15. Therefore, the dust collecting box 12 has a space in which the outer casing 10 is partitioned (separated) into a space communicating with the outer flow path 35 and communicating with the inner flow path 36. Alternatively, the dust box 12 is configured to partition (separate) the outer casing 10 into a space communicating with the outer flow path 35 and a space facing the filter 15. In the filter 15, it is to collect lighter dust and dust from other dust and other air. The air that has passed through the filter 15 and is almost free of dust is passed through the auxiliary filter and flows into the intake duct 27, and is sucked from the suction port of the upper portion of the electric blower 28 through the opening of the lower portion of the intake duct 27. The air discharged from the discharge port on the side of the electric blower 28 passes through the exhaust duct 40 to reach the filter 29, and the residual dust is collected by the filter 29. The air passing through the filter 29 passes through the periphery of the electric blower 28 or the electric wire reel chamber (not shown), the gap of the lower portion of the cleaner body 1, and the like, and is then discharged from the main body exhaust port 30 toward the outside of the cleaner body 1. In particular, since the filter 29 has the dust collecting efficiency of the same degree or more as that of the filter used for the air cleaner, the air discharged from the cleaner body 1 toward the outside is purified into an air cleaner. The same degree or more than -45- 201103484 degrees. Fig. 2(A) is a perspective view showing the dust collecting device 2 of the embodiment of the present invention, and Fig. 2(B) is a sectional view showing the dust collecting device 2 of the embodiment of the present invention as seen from the side. . The user can lift the dust collecting device 2 from the cleaner body 1 by holding the handle 16 to lift the dust collecting device 2 upward. However, it is also possible to leave the dust separating unit 4 in the cleaner body 1 and remove only the dust containing unit 5 from the cleaner body 1. As shown in Fig. 2(A), the outer shape of the cross section of the dust separating portion 4 viewed from the axial direction is substantially circular. The outer shape of the cross section of the dust accommodating portion 5 is substantially circular at the portion of the front cover 11, but the portion of the front cover 11 is substantially quadrangular, and the portion of the filter 15 has a substantially square shape. As shown in Fig. 2(B), the opening direction of one end of the outer casing 10 in the axial direction and the opening direction of the other end of the outer casing 10 are not in a straight line, and are different from each other by 45 to 50 degrees. That is, the axial direction of the dust accommodating portion 5 is curved slightly forward than the middle. As described above, the end face of the dust collecting device 2 in the axial direction (the portion of the inlet pipe 3) is in the direction of the tip micro direction toward the lower side (the direction of gravity action), and the other end face in the axial direction of the dust collecting device 2 (the filter 15 Partially, the direction of the lower side (gravity action direction) is slightly lower than the one end surface of the dust collecting device 2 and the other end surface of the axial direction, and the vertical surface (gravity action direction) is used as the reference. When the collecting device 2 is lifted upward, the user does not get stuck, and the user can easily remove the dust collecting device 2 from the cleaner body 1. Fig. 3(A) is a perspective view showing the inner cylinder 7 and the outer cylinder 6 according to the embodiment of the present invention, and Fig. 3(B) is a perspective view showing the back side of the inner cylinder 7 according to the embodiment of the present invention. . One end surface of the outer cylinder 6 is closed except for the formed portion of the inlet pipe 3 - 46 - 201103484, and the other end surface of the outer cylinder 6 is open. The inner cylinder 7 is provided with an annular extension portion 34 at one end of the cylindrical portion. As shown in Fig. 3(A), the outer cylinder 6 is inserted from the cylindrical portion of the inner cylinder 7 in the outer cylinder 6 toward the axial direction. The outer peripheral end of the end face abuts against the outer peripheral end of the outer peripheral portion 34, and the inner cylinder 7 is formed in the outer cylinder 6. As shown in Fig. 3(A), the opening direction of the inlet pipe 3 is opposite to the opening of the recessed portion 8. The opening direction of the recessed portion 8 toward the outer peripheral end portion of the inner cylinder 7 faces the substantially lower side, and the opening direction of the guide tube 38 in the circumferential direction is a counterclockwise direction. Further, the direction of the opening of the guide tube 38 in the circumferential direction may be in the direction of the clockwise direction. Further, the upper portion of the extension portion 34 has a hole that penetrates in the axial direction, that is, the upper portion of the extension portion 34 is an opening. The left wall surface ' of the opening is higher than the right wall surface. That is, the wall surface (left wall surface) of the opening of the upper portion of the extension portion 34 is opposite to the opening direction of the guide tube 38 in the circumferential direction, and is higher than the other wall surface (right wall surface). On the other hand, the surface of the extension portion 34 has a spiral shape and has a function of smoothly guiding the air toward the opening of the upper portion of the extension portion 34.

Fig. 4(A) is a perspective view showing a state in which the front cover 11 of the dust portion 5 according to the embodiment of the present invention is opened, and Fig. 4(B) is filtered at the rear of the dust containing portion 5 of the embodiment of the present invention. The stereoscopic view of the opener is displayed. As shown in Fig. 4(A), when the front cover 11 is rotated and opened in the downward direction of the shaft 31, the dust box 12 is also formed by the shaft 14 as a branch. 4mm left-handed co-bacterial effect stainless steel alloy is thinner in the axial direction, in the shape of the shape of the part, by the combination, the end can be formed into a molded resin with a resin, so that the state is the fulcrum The point is swung in the direction of -48- 201103484. At this time, the dust box 12 is divided into upper and lower sides with the shaft 1 3 as a fulcrum. The opening of the dust box 1 2 when ejected from the sputum housing portion 5 is expanded as compared with the opening of the dust box 12 when it is housed in the dust accommodating portion 5. Thereby, the dust adhering to the inner surface of the dust box 1 2 can be easily scraped off. When the user wears the fiber paper along the inner surface of the dust box 12, the end portion of the fiber paper is sandwiched between the frame of the opening of the dust box 1 2 and the outer peripheral end of the front cover 1 1 . It can inhibit the fiber paper from shifting or falling off. As shown in Fig. 4(B), the filter 15 is pivotally opened in the lower direction with the shaft 3 2 as a fulcrum. Thereby, the user can easily discharge the dust accumulated outside the dust collecting case 12 in the casing 10, and the dust adhering to the side surface of the casing 10 of the filter 15 can be easily removed. Fig. 5(A) is a front view of the front cover 11 of the dust accommodating portion 5 of the embodiment of the present invention as seen from the outside of the dust containing portion, and Fig. 5(B) shows the present invention from the inside of the dust containing portion. A front view of the front cover 11 of the dust receiving portion 5 of the embodiment. Further, the hatched portion in the figure is not a cross section, and the front surface is shown. The lower end of the front cover 11 is provided with a shaft 31 that is rotatably supported by the outer casing 10. The front cover 11 has a substantially circular shape. The substantially circular portion on the outer side of the hatched portion shown in Fig. 5(A) is an outer peripheral end that can abut against the other end surface of the dust separating portion 4 in the axial direction. The substantially circular portion on the inner side of the hatched portion shown in Fig. 5(A) is an outer peripheral end that can abut against the other end surface of the inner cylinder 7 of the inner separation portion 4 in the axial direction. On the upper side of the front cover 11, i.e., the side opposite to the shaft 31, an opening of the outer flow path 35 is formed between the substantially circular portion on the outer side of the oblique portion and the substantially circular portion on the inner side. The opening position of the front side of the outer flow path 35 (outside the dust accommodation portion 5) may be on the left and right sides or the lower side of the front cover 1 1 , but the rear side of the side flow path 35 of the outer side - 49 - 201103484 When the opening position of the inside of the dust collecting portion 5 is on the upper side of the front cover 1 1 , in order to shorten the length of the outer flow path 35 and reduce the pressure loss of the air, the opening position on the surface side of the outer flow path 35 is also The upper side of the front cover 11 is preferred. On the other hand, an opening of the inner flow path 36 is formed inside the inner tube 7. In the front view of Fig. 5(A), the opening area of the inner flow path 36 is larger than the opening area of the outer flow path 35, but the upper semicircular portion in the inner tube 7 is formed with a recessed portion 39. Therefore, when the flow rate of the air outside the inner cylinder 7 is larger than the flow rate of the air in the inner cylinder 7, the opening area of the inner flow path 36 is smaller than the opening area of the outer flow path 35 as the substantial flow path area. Further, the portion between the substantially circular portion on the outer side of the oblique line portion and the substantially circular portion on the inner side that does not form the outer flow path 35 is closed. The substantially circular portion on the outer side of the hatched portion shown in Fig. 5(B) is a part of the outer peripheral end of the one end surface in the axial direction of the outer casing 1 and the outer peripheral end of the opening of the dust collecting case I2. As shown in Fig. 5(B), an opening of the outer flow path 35 is formed on the side of the center line in the vertical direction of the front cover 1 1. Therefore, when the electric vacuum cleaner is stopped, the dust accumulated in the dust collecting case 12 can be prevented from flowing back toward the outer flow path 35 and the dust separating portion 4. However, the opening of the outer flow path 35 may be formed in the central portion of the center line of the front cover 11 in the vertical direction. Further, it is preferable to form a check valve (not shown) that covers the outer flow path 35. Thereby, even when the electric vacuum cleaner is stopped, the dust accumulated in the dust collecting case 12 can be prevented from flowing back toward the outer flow path 35 and the dust separating unit 4. On the other hand, an opening of the inner flow path 36 is formed in the vicinity of the lower end of the front cover. However, the opening position ' of the inner channel 36 may be the lower side or the left side or the upper side with respect to the opening position of the outer channel 35. Further, the oblique line portion on the upper side of the opening of the inner side flow path 3 6 - 50 - 201103484 is a lower end which abuts on the outer peripheral end of the opening of the dust collecting case 1 2 . As shown in Fig. 5(B), on the back side of the front cover 1 (inside of the dust containing portion 5), the opening area of the outer flow path 35 is larger than the opening area of the inner flow path 36. Further, as shown in FIGS. 5(A) and 5(B), the opening area (Fig. 5(B)) of the other end (back side) of the outer flow path 35 is the outer flow path 3 The opening area (Fig. 5(A)) of one end (surface side) of 5 is large. That is, the outer flow path 35 is expanded from one end toward the other end. On the other hand, as shown in FIGS. 5(A) and 5(B), the opening area (Fig. 5(B)) of the other end (back side) of the inner channel 36 is the ratio of the inner channel 36. The opening area (Fig. 5(A)) of one end (surface side) is also small. That is, the inner flow path 36 is narrowed from one end toward the other end. Fig. 6 is a front elevational view showing the front cover of the dust containing portion according to the embodiment of the present invention as seen from the side of the dust separating portion. Further, as in the fifth drawing, the hatched portion in the drawing is not a cross section, and the front surface is displayed. The substantially circular oblique portion is abutted against the outer peripheral end of the front cover 11. As shown in Fig. 6, the outer peripheral end of the opening of the outer end of the outer casing 10 in the axial direction is a part of the outer peripheral end of the opening of the dust collecting case 12. Further, as shown in Fig. 6, 80% or more of the opening of one end surface of the outer casing 1 in the axial direction is occupied by the opening of the dust collecting case 12. On the other hand, a region other than the opening of the dust collecting case 12 of the opening of the casing 10 (about 20% or less is left) faces the opening of the inner channel 36 and communicates with the inner channel 36.

而設置，唇部69，係爲了保持位於內側流路36之內筒7與 前蓋1 1的氣密性而設置。而，唇部68及唇部69，爲從內周 側朝向外周側延伸形成。因此，於集塵分離部4安裝上集 塵容納部5時，唇部68及唇部69會抵接於集塵容納部5的前 201103484 蓋1 1，並彈性變形，保持氣密性。再者，電動送風機28動 作，而產生吸引力時，集塵分離部4會被集塵容納部5吸附 接近，唇部68及唇部69又更彈性變形，保持氣密性。因此 ，相較於電動送風機28停止之場合，電動送風機28動作之 場合，爲集塵容納部5與集塵分離部4之間的氣密性的保持 力會增加。不過，唇部69，以從外周側朝向內周側延伸形 成爲佳，唇部69，若從內周側朝向外周側延伸形成，則於 外側流路3 5的終端之內周側的部分1 00，會卡住來自外側 流路35的塵埃、或漏出。藉由將唇部69，從外周側朝向內 周側延伸形成，可抑制塵埃卡住、或漏出。又，墊片9， 包含唇部68及唇部69,以藉由橡膠等之彈性材料一體成形 較佳。 圓筒部分的內周側（唇部69的內周側）之大致上半部 ，爲被具備有朝向圓筒部分的軸方向內側凹陷的凹陷部3 9 之墊片9所封閉，圓筒部分的內周側（唇部69的內周側） 之大致下半部，爲沒有被墊片9封閉而呈開口。該開口， 形成內側流路36。墊片9藉由被封閉部分的面積，開口部 分的面積與相同亦可，較小亦可。藉由把被墊片9封閉之 部分的面積，作得比開口部分的面積還小，可減低流經內 側流路3 6的空氣之能量損失或噪音。 第14圖，爲從上側觀察本發明之實施例2的內筒7之側 面圖。外側流路35的一端開口的下游側壁面65 (左壁面） 爲比上游側壁面66 (右壁面）還高，而僅以該高度的相差 量dH呈開口。藉此，圓筒部分之外側的流，可沿著下游側 ζ -61 - 201103484 壁面6 5平順地改向朝軸方向，含於迴旋流的塵埃也 於朝向塵埃容納部5流動。外側流路35的內壁面101 其爲外側流路35的入口之下游側壁面65朝向其爲外 35的出口之內筒7的軸方向另一端面，朝向圓周方 或是彎曲地形成。藉此，塵埃可平順地流動於外側 內。又，由於外側流路3 5的內壁面1 0 1呈傾斜或彎 於從外側流路3 5出來的空氣流，不僅只軸方向的成 留有圓周方向的成分（迴旋成分）。 第1 5圖，爲從右側觀察本發明之實施例2的內有 面圖。外延部3 4，爲朝向外側流路3 5 (從下側朝向 ，軸方向的高度較低。外延部34的表面，於第1周 向外側流路35形成螺旋狀。若將圓柱部分57的高度 ，將在梯形圓錐部分58的最高位置之高度作爲H2時 有Η 1>H2的關係。又，若將在引導管38的最高位置 作爲H3時，則具有H3>H1的關係。貫通孔33，爲只 於從至少引導管終端部5 9到外側流路3 5的一端開口 可，其中，比起外側流路3 5側亦只要集中形成於引 端部5 9側即可。於外側流路3 5側，由於比起流入貫 的流量，流入外側流路3 5的流量較多，故於外側流 形成貫通孔3 3是沒有意義的。 第1 6圖，爲從右側觀察本發明之實施例2的內有 面圖。若將凹陷部8的軸方向處之最深部分的深度 時，則具有H4<H1的關係。亦即，凹陷部8的深度 圓柱部分57的高度還淺。從立體角度來看，凹陷商 變得易 ，爲從 側流路 向傾斜 流路3 5 曲，故 分，亦 5 7之側 上側） *爲朝 作爲H1 ，則具 之高度 要形成 之間即 導管終 通孔3 3 路3 5側 苛7之斷 作爲H4 ，爲比 β 8爲半 -62- 201103484 球狀’且凹陷部8的斷面形狀，如第14圖所示般爲大致半 圓。因此，凹陷部8的深度H4，幾乎與圓柱部分57的外形 半徑R 1或凹陷部8的開口部的半徑相等。因此，凹陷部8的 軸方向的形成位置，爲覆蓋於貫通孔3 3的軸方向的形成位 置。凹陷部8的深度H4若太深，則從貫通孔33被吸入空氣 的流量會變少’另一方面，凹陷部8的深度H4若太淺，則 於凹陷部8會有塵埃堵塞之虞。亦考慮射出成形的容易度 ’凹陷部8以作成半球狀爲佳。不過，凹陷部8並非限定於 半球狀，亦可爲比半球狀還淺的橢圓狀或深橢圓狀。而， 以引導管3 8的底面的一端，於凹陷部8的底面沒有階段差 地平緩接合，引導管38的底面的另一端，於外延部34的表 面沒有階段差地平緩接合，引導管3 8的底面，從引導管3 8 的底面的一端直至引導管38的底面的另一端爲止爲沒有階 段差地平緩傾斜較佳。又，因從半球狀的凹陷部8的一半 有引導管3 8，故若除去引導管3 8的部分，實際上凹陷部8 則係成爲1/4球狀。 而’迴旋於圓筒部分的外側之空氣，爲從外側流路3 5 被排出（氣流6 2 )。從貫通孔3 3流入圓筒部分的內側之空 氣’爲在圓筒部分內的空間及外延部3 4內的空間，一面小 小地迴旋，一面從內側流路36被排出（氣流63 )。從貫通 孔3 3流入圓筒部分的內側之空氣，相較於在圓筒部分的外 側迴旋之空氣，其能量損失相當大，不過，於塵埃沒有蓄 積於塵埃容納部5之狀態，從貫通孔33流入圓筒部分的內 側之空氣的流量，相較於在圓筒部分的外側迴旋之空氣的 t -63- 201103484 流量，爲相當少，故整體來看則能量損失很少。 第17圖（a)，爲從正面觀察本發明之實施例2的塵埃 分離部之立體圖，且第1 7圖（a )，爲從右側側面觀察本 發明之實施例2的塵埃分離部之側面圖。第1 7圖中的箭頭 ’爲顯示圓柱部分57的軸方向前端部及入口管3的出口端 部之抵接範圍。圓柱部分57的半圓形狀的軸方向前端部， 爲與入口管3的出口端部抵接。組合精度的問題來看，圓 柱部分57的軸方向前端部與入口管3的出口端部爲沒有完 全抵接，即使有多少之間隙（1 mm以下）也沒關係。不過 ，若有間隙則空氣會洩漏，能量損失會增加，又噪音也會 變大。因此，將圓柱部分57的軸方向前端部及入口管3的 出口端部作成氣密之場合，亦可使墊片（密封構件）中介 於圓柱部分57的軸方向前端部與入口管3的出口端部之間 〇 另一方面，如斷面放大圖所示，於外筒7的軸方向端 面的內側，跨及於引導管38的軸方向前端部的全長，沿著 引導管38的軸方向前端部形成階段差》將外筒7的軸方向 端面的厚度作爲D2，將比對應於外筒7的軸方向端面的引 導管38的軸方向前端部之部分更內周側的厚度作爲D3時， 則具有D2>D3的關係，因而產生（D3 — D2 )的階段差。例 如，02爲3mm左右，而D3爲2mm左右。因此，階段差，爲 1mm左右。因此，外筒7的軸方向端面的內側，比起對應 於引導管38的軸方向前端部之部分，在內周側爲較薄。而 ，如斷面放大圖所示，於以引導管38的軸方向前端部抵接 ⑧ -64- 201103484 於該階段差之方式組合內筒6及外筒7。該階段差，由於具 有外筒7的軸方向端面的內側與引導管38的軸方向前端部 之間的密封功能，故藉由該階段差，可減低空氣的能量損 失，或減低噪音。於加工精度或組合精度差，或於電動送 風機28運轉，使內筒7被朝向塵埃容納部5側吸附靠近，而 引導管38的軸方向前端部，沒有完全抵接於外筒6的軸方 向端面的內側時，階段差亦可抑制空氣的洩漏。引導管3 8 之軸方向前端部的厚度，相較於圓柱部分57的軸方向前端 部的厚度D1，由於爲較薄，難以形成墊片等的密封構件， 故以藉由階段差實現密封功能爲佳。又，入口管3，以與 外筒6成形一體爲佳。 於外筒7的內周面（側壁面），且，接近外筒7的軸方 向端面（上表面）之側，且，於從引導管3 8的出口開口直 至外側流路3 5的入口開口之間，形成整流板1 02 (肋條、 翅膀）。整流板1 02的形成位置，亦可爲從引導管3 8的出 口開口直至外側流路3 5的入口開口之間的中央附近，亦可 爲比中央更靠引導管3 8的出口開口側。整流板1 02爲板狀 ，朝向圓周方向延伸形成。整流板102圓周方向的長度， 爲比從引導管3 8的出口開口直至外側流路3 5的入口開口距 離還小極多。如第1 7圖（b )所示，整流板1 0 2的形成方向 ，爲從整流板1 02的形成位置朝向外側流路3 5的入口開口 之方向。整流板1〇2可爲1片，亦可爲複數片。於整流板 102與外延部34之間有很大的縫隙，於該大縫隙當然有空 氣流動。於整流板1 0 2與外筒7的軸方向端面的內側之間亦 f* -65- 201103484 有較小的縫隙，該大縫隙亦有空氣流動。該整流板102及 外筒7的軸方向端面的內側之間亦形成有較小的縫隙’由 於藉由形成空氣流’在整流板1 〇2的兩面產生流’故可抑 制在整流板1 〇2的下游端之亂流的產生。而’藉由該整流 板1 02，可使迴旋流朝向外側流路3 5的入口開口。因此’ 從引導管38流入的空氣，由於不會在外筒7迴旋好幾周’ 而被朝向外側流路3 5引導，故可減低空氣的能量損失。又 ，並非流速較慢的內周側（內筒7的外周面），而是形成 於流速較快的外周側（外筒6的內周面）’故整流板102的 形狀即使很小，亦有使迴旋流轉向的效果。由於可縮小整 流板1 02，故可將空氣流的紊亂減小可減低空氣的能量損 失。 根據本發明之實施例2，藉由在內筒7的前端部形成凹 陷部8使其具有迴旋功能，可縮短集塵裝置2的軸方向的長 度，可將吸塵器本體1作得更小巧。 〔實施例3〕 將實施例1的塵埃分離部4及塵埃容納部5的詳細，作 爲實施例3予以說明。

)，該第2構件爲在對應於第2集麈部側的軸 方向另一端部的第1構件之位置，具備有與第1構件的大致 垂直之面相向之面。而，根據本發明’在使用者將第2集 塵部裝著於吸塵器本體1時，藉由第1構件及第2構件可引 導第2集塵部的插入，故對於使用者而言’第2集塵部的裝 著變得較容易，又，可抑制相對於第1集塵部及吸塵器本 體1之第2集塵部的移位，故可保持第1集塵部與第2集塵部 之間或第2集塵部與吸麈器本體1之間的氣密性’可抑制電 氣吸塵器之吸入工作效率的降低。再者’亦可抑制因空氣 -67- 201103484 洩漏引起之噪音的產生。 又，本發明之電氣吸塵器，其特徵爲：具備有： 於第1集塵部（例如：塵埃分離部4 )與第2集塵部（ :塵埃容納部5 )所連通之部分的第1密封構件（例如 片9)，以及中介於第2集塵部與吸塵器本體1所連通 分的第2密封構件（例如：墊片2 5 )，第1密封構件， 於第2密封構件，是以彈性力較大的材料所構成。而 據本發明，可保持相較於第2集塵部與吸塵器本體1之 較易分離之第1集塵部與第2集塵部之間的氣密性，可 電氣吸塵器之吸入工作效率的降低。再者，亦可抑制 氣浅漏引起之噪音的產生。 又’本發明之電氣吸塵器，其特徵爲：具備有： 於第1集塵部（例如：塵埃分離部4)與第2集塵部（ :塵埃容納部5 )所連通之部分的第1密封構件（例如 片9)，以及中介於第2集塵部與吸塵器本體1所連通 分的第2密封構件（例如：墊片25 )，第2集塵部，爲 第1密封構件及第2密封構件，被支撐於裝著有第1集 的吸塵器本體1。而，根據本發明，使用者可容易地；f 集塵部從吸塵器本體1卸取下來，塵埃的排出操作變 容易。再者’根據本發明，可保持第1集塵部與第2集 之間及第2集塵部與吸塵器本體1之間的氣密性，可抑 氣吸塵器之吸入工作效率的降低。再者，亦可抑制因 洩漏引起之噪音的產生。 又’本發明之電氣吸塵器，其特徵爲：具備有從 中介 例如 :墊 之部 相較 ，根 間爲 抑制 因空 中介 例如 :墊 之部 藉由 塵部 Ϊ第2 得較 塵部 制電 空氣 集塵 -68- 201103484 裝置2的軸方向一端部跨及於與集塵裝置2的軸方向一端面 相向之吸塵器本體1的壁面部（例如：前側壁面），限制 集塵裝置2從本體吸氣口開離之構件（例如：突起構件72 及卡合孔82)。而’根據本發明，可保持吸塵器本體1與 塵埃分離部4之間的氣密性，可抑制電氣吸麈器之吸入工 作效率的降低。再者’亦可抑制因空氣洩漏引起之噪音的 產生。 又’本發明之電氣吸塵器，其特徵爲：具備有將集塵 裝置2的軸方向一端部及與集塵裝置2的軸方向一端面相向 之吸塵器本體1的壁面部（例如：前側壁面）予以卡合之 構件（例如：突起構件7 2及卡合孔8 2 )。而，根據本發明 ，可保持吸塵器本體1與塵埃分離部4之間的氣密性，可抑 制電氣吸塵器之吸入工作效率的降低。再者，亦可抑制因 空氣洩漏引起之噪音的產生。 第1 8圖，爲從右側觀察本發明之實施例3的吸塵器本 體1之側面圖。第1 9圖，爲從右上側觀察本發明之實施例3 的吸塵器本體1之立體圖。特別是，顯示使用者將上護罩 5 6打開，將塵埃分離部4留於吸塵器本體1而僅將塵埃容納 部5朝向大致上方向拉出之狀態。虛線箭頭，爲顯示塵埃 容納部5的拉出方向。虛線箭頭的方向，爲相對於吸塵器 本體1的底面或放置了吸塵器本體〗的面（例如：地板面） 爲垂直方向或是比垂直方向稍微前側之方向（例如：5度 )° 一體成形於塵埃分離部4的入口管3的軸方向一端爲抵 -69- 201103484 接於墊片22’塵埃分離部4的軸方向另一端的下部，爲藉 由卡合構件71 (固定構件）被卡合、固定於吸塵器本體1 。藉由塵埃分離部4的軸方向另一端的下部及卡合構件71 而實現了卡合機構。因此，只要使用者沒有操作卡合構件 71，則塵埃分離部4’爲被固定於吸塵器本體1。另—方面 ’於塵埃容納部5裝著於吸塵器本體1之狀態，爲塵埃容納 部5的軸方向一端，夾介墊片9抵接於塵埃分離部4的軸方 向另一端，塵埃容納部5的軸方向另一端，爲夾介墊片25 抵接於吸塵器本體1，塵埃容納部5的上表面係被上護罩56 覆蓋’塵埃容納部5之其他部分，爲沒有抵接於塵埃分離 部4或吸塵器本體1。亦即，塵埃容納部5，爲在其軸方向 一端及另一端處，浮於塵埃分離部4或吸塵器本體1之狀態 下被朝向上方支撐。因此，使用者，將上護罩56打開，只 要持住把手1 6將塵埃容納部5朝向虛線箭頭方向拉出，而 仍將塵埃分離部4留於吸塵器本體1，則可僅將塵埃容納部 5從吸塵器本體1卸取下來。亦即，可將塵埃容納部5與塵 埃分離部4呈獨立地從吸塵器本體1卸取下來。因此，對於 使用者而言，麈埃容納部5的卸取很容易。塵埃的大部分 ，因被蓄積、壓縮於塵埃容納部5，故使用者，即使不用 進行將集塵裝置2從吸塵器本體1卸取下來再將塵埃分離部 4及塵埃容納部5予以分離並將塵埃容納部5內的塵埃排出 之所謂3段階的操作，而仍可將塵埃分離部4留於吸塵器本 體1地進行僅將塵埃容納部5從吸塵器本體1卸取下來，並 將塵埃容納部5內的塵埃排出之所謂2段階的操作，對於使 -70- 201103484 用者而言，塵埃的排出操作變得較容易。又，把手16，由 於爲從塵埃容納部5的後端跨及於前側地平緩傾斜，故使 用者’可將塵埃容納部5朝向垂直方向或比垂直方向稍微 前側之方向拉出。再者，塵埃容納部5爲僅藉由墊片9及墊 片25被支撐於塵埃分離部4及吸塵器本體1，而塵埃容納部 5的其他部分爲從吸塵器本體1浮起之狀態，因此電動送風 機28動作而產生吸引力時，藉由該吸引力，塵埃容納部5 可朝向塵埃分離部4側及吸塵器本體1的後側壁面側，將墊 片9及墊片25朝向按壓方向移位，故可保持塵埃分離部4與 塵埃容納部5之間的氣密性，以及塵埃容納部5與吸塵器本 體1之間的氣密性。 於塵埃容納部5的軸方向一端的軸心附近，形成有用 以引導或是輔助塵埃容納部5的裝卸之突起構件70。突起 構件70，爲從塵埃容納部5的軸方向一端面朝向軸方向突 出形成。突起構件70，與前蓋1 1爲相同材料，且以與前蓋 Η —體成形爲佳，沒有一體成形也可以。突起構件70的前 端面，爲朝向大致拉出方向亦即相對於吸麈器本體1的底 面或是放置了吸塵器本體1的面，爲呈大致垂直之方向或 是朝向比垂直方向稍微前側之方向（例如：〇〜5度之範圍 內的預定角度）形成。藉由突起構件7〇及塵埃分離部4的 凹陷部39而實現了引導機構。特別是，使用者將塵埃容納 部5裝著於吸塵器本體1時’首先將塵埃容納部5的把手16 持住，將突起構件7〇的前端面抵接於塵埃分離部4的凹陷 部3 9的前側壁面，其後將塵埃容納部5壓入，若以一般的 -71 - 201103484 力不能再壓入時，將上護罩56閉合，則可將塵埃容納部5 裝著於吸塵器本體1。因此，對於使用者而言，塵埃容納 部5的裝著也很容易。又，亦可於塵埃容納部5不能被壓入 至特定位置時，以上護罩56不能閉合之方式形成上護罩56 的內側形狀（抵接於塵埃容納部5的面的形狀）。 第20圖，爲從右側觀察本發明之實施例3的吸塵器本 體1之側面圖。第2 1圖，爲從右上側觀察本發明之實施例3 的吸塵器本體1之立體圖。特別是顯示從吸塵器本體1將塵 埃容納部5卸取下來後，將麈埃分離部4朝向大致上方向拉 出之狀態。虛線箭頭，爲顯示塵埃分離部4的拉出方向。 虛線箭頭的方向，相對於吸塵器本體1的底面或是放置了 吸塵器本體1的面，爲呈大致垂直之方向。 卡合構件7 1，呈板狀，其後側爲被軸支撐於吸塵器本 體1。再者，以使卡合構件7 1的前側朝向吸塵器本體1側彈 推之方式，於軸的周圍或是於卡合構件71本身安裝有彈簧 。於裝著有塵埃分離部4之狀態下，塵埃分離部4的軸方向 另一端的下部爲卡合於卡合構件7 1的前側，藉由彈簧的彈 推力使塵埃分離部4不會脫落地固定。塵埃分離部4，於入 口管3或塵埃分離部4的軸方向另一端的下部以外，塵埃分 離部4的底面亦可被支撐於吸塵器本體1。 而，使用者，只要以一方的手，對抗彈簧的彈推力， 解除藉由卡合構件71之卡合，並以另一方的手，持住凹陷 部39的內側或是外側，將塵埃分離部4朝向虛線箭頭方向 拉出，則可將塵埃分離部4從吸塵器本體1卸取下來。因此 -72- 201103484 ，使用者，可容易地將麈埃分離部4從吸塵器本體1卸取下 來。將塵埃分離部4裝著於吸塵器本體1時，使用者’持住 凹陷部3 9的內側或是外側，首先將入口管3的一端抵接於 墊片22，其後藉由將塵埃分離部4壓入，卡合構件71的前 側會越過塵埃分離部4的軸方向一端的下部而達成卡合’ 可將麈埃分離部4裝著於吸塵器本體1。因此，使用者’可 容易地將塵埃分離部4裝著於吸塵器本體1。又，塵埃容納 部5的軸方向另一端面，於與塵埃容納部5的軸方向另一端 相向之吸塵器本體1的後側壁面（電動送風機28的前方壁 面）幾乎跨及於前面地形成，不過若從吸塵器本體1的前 側來看，則吸氣導管2 7的入口開口（輔助過濾器2 6 )，爲 靠近左側地形成。又，吸塵器本體1的後側壁面，爲朝向 相對於吸塵器本體1的底面或是放置了吸塵器本體1的面呈 大致垂直之方向形成。 再者，於比塵埃分離部4的軸方向一端面之外側的入 口管3更上側處，形成有用以將塵埃分離部4的軸方向前端 側卡在吸塵器本體1的前側的內壁之突起構件72 (卡合構 件）。若電動送風機28動作而產生吸引力時，藉由該吸引 力，塵埃容納部5會欲朝向後側移位，再者，藉由該吸引 力，塵埃分離部4也會在集塵裝置2的軸方向處朝向塵埃容 納部5側移位，其結果，塵埃分離部4會欲從吸塵器本體1 浮起。亦即，塵埃分離部4的軸方向另一端，因被卡合構 件7 1卡合，故塵埃分離部4的軸方向另一端的移位受到限 制。另一方面，塵埃分離部4的軸方向一端，由於僅靠入 -73- 201103484 口管3的軸方向一端抵接於擎片22是無法限制該移位，故 會從墊片22移位或分離，而無法保持氣密性，招致吸引力 的降低，產生噪音。在此，藉由突起構件72，可防止入口 管3的軸方向一端從墊片22移位或分離，抑制吸引力的降 低或噪音的產生。 第22圖，爲從右側觀察本發明之實施例3的集塵裝置2 之側面圖。特別是顯示塵埃分離部4及塵埃容納部5被分離 的狀態。 於塵埃容納部5的軸方向另一端，設置有過濾器15。 過濾器15，爲於斷面形狀呈大致四角形的框體78內形成過 濾器構件79。跨及於過濾器15的外周的全周，形成有大致 四角形的墊片25。因此，墊片25，係與過濾器15同爲相對 於外殼1 〇爲可轉動。墊片25，使可朝向前後方向伸縮地折 成褶邊爲佳。而，如第22圖般從側面觀察時，墊片25，爲 比過濾器1 5配置於更靠近外殼1 0側。亦即，爲比過濾器1 5 ，更朝向墊片25外側（電動送風機28側）突出。如第22圖 般從側面觀察時之過濾器1 5的後端面的形成方向，相對於 吸塵器本體1的底面或是放置了吸塵器本體1的面，爲呈大 致垂直，且爲沿著吸塵器本體1的後側壁面之方向（例如 :平行）。另一方面，如第2 2圖般從側面觀察時之墊片2 5 的後端面的形成方向’相對於吸塵器本體1的底面或是放 置了吸塵器本體1的面之垂線呈傾斜角度b。亦即，墊片25 的後端面的形成方向，相對於塵埃容納部5的拉出方向也 傾斜大致角度b。因此，墊片2 5的後端面，相對於過濾器 ⑧ -74- 201103484 1 5的後端面也傾斜角度b。相對於墊片25之後端面的上端 的位置，墊片2 5之後端面的下端的位置’爲於前側（外殻 10側）。如第22圖般從側面觀察時’墊片25之後端面的上 端的位置，是與過濾器1 5之後端面的上端的位置大致一致 ，不過墊片2 5之後端面的下端的位置’是位在比過濾器15 的後端面的下端的位置更前側處。例如，角度b ’爲5度〜 10度之範圍內的預定角度。還有’吸塵器本體1的後側壁 面·•其之與墊片25相向之壁面是形成在比其之與過濾器15 相向之壁面更前側處。再者’相對於過濾器1 5的位置而言 ，相較於墊片25的位置’相對於吸塵器本體1之與過濾器 15相向之壁面的位置之與墊片25相向之壁面的位置’是以 位在前側爲佳。藉此，使用者將塵埃容納部5壓入時’在 過濾器15抵接於吸塵器本體1之前，會將墊片25抵接於吸 塵器本體1。 比起中介於塵埃分離部4與塵埃容納部5之間的墊片9 ，中介於塵埃容納部5與吸塵器本體1之間的墊片2 5 ’以由 黏性較低的材料所構成較佳。此爲，相較於墊片9的形成 方向，由於墊片25的形成方向，接近於塵埃容納部5的拉 出方向，亦即相對於吸塵器本體1的底面或是放置了吸塵 器本體1的面，爲呈大致垂直之方向，故從吸塵器本體1將 塵埃容納部5予以裝卸時會受到很大的剪斷力。若墊片25 的黏性很高，則從吸塵器本體1將塵埃容納部5予以裝卸時 ，墊片25會緊黏於墊片承受面80，於裝卸時需要很大的力 氣。在此，比起墊片9，藉由將墊片25的黏性作得較低， ϋ -75- 201103484 塵埃容納部5從吸塵器本體1的裝卸會變得容易。爲了將墊 片2 5的黏性作得比起墊片9還低，而用彈性力比墊片9還小 的材料構成墊片2 5。換言之，用彈性力比墊片2 5還大的材 料構成墊片9。相對於塵埃分離部4大致被固定於吸塵器本 體1之狀態，塵埃容納部5爲從吸塵器本體1浮起之狀態， 再者，由於比起墊片25的位置，墊片9的位置在流路上爲 距離電動送風機28較遠，故相較於塵埃容納部5與吸塵器 本體1之間，塵埃分離部4與塵埃容納部5之間較易分離。 藉由將墊片9的彈性力作得比墊片2 5還大，而以墊片9的彈 性變形許容塵埃分離部4與麈埃容納部5之間的分離，可得 到保持較易分離之塵埃分離部4與塵埃容納部5之間的氣密 性之所謂其他的效果。 如第22圖般從側面觀察時之突起構件70的前端面的形 成方向，爲相對於與吸塵器本體1的底面或是放置了吸塵 器本體1的面呈垂直之垂線傾斜角度c。相對於塵埃容納部 5的拉出方向也傾斜大致角度c。相對於突起構件70之前端 面的上端的位置，突起構件70的前端面的下端的位置，爲 於後側（外殼1 0側）。例如，角度c，爲〇〜5度之範圍內 的預定角度。因此，具有角度cS角度b的關係。將角度b 設定得較大時，亦可將角度c設定得較小，相反地，將角 度b設定得較小時，亦可將角度c設定得較大。例如，若將 角度b設定成1〇度時，亦可將角度c設定成0。亦即，只要 墊片2 5的後端面夠傾斜，則突起構件7 0的前端面亦可不傾 斜。亦可將角度b設定成5度，將角度c設定成5度。又’突 ⑧ -76- 201103484 起構件70的前端面雖是與凹陷部39的前側壁面相向’不過 接受突起構件70的前端面之凹陷部39的前側壁面的形成方 向，相對於吸塵器本體1的底面或是吸塵器本體1所放置的 面，亦可爲大致垂直。如此，藉由將突起構件70的前端面 及墊片2 5的後端面作成倒「八」字型狀，對於使用者而言 ，對於吸塵器本體1之塵埃容納部5的裝卸會變得容易。特 別是藉由增大相對於突起構件7〇的形成角度c來使接觸面 積加大，並藉由增大黏性較高之墊片25的形成角度b’可 使塵埃容納部5的裝卸變得容易。 再者，於過濾器15的框體78的下部，具備有相對於過 濾器15的後端面爲突出之凸部73。凸部73，爲朝向與過濾 器15的後端面呈垂直之方向突出。另一方面，在與吸塵器 本體1的後側壁面中之過濾器1 5的框體78相向之位置的下 部，亦即與過濾器15的凸部73相向之位置，形成有凹部81 (參照第26圖）。該凸部73及凹陷部8 1爲具備有對應之 形狀。因此，凹部8 1，爲朝向與吸塵器本體1的後側壁面 呈垂直之方向凹陷。而，藉由該凸部73及凹部81，實現了 在將塵埃容納部5裝著於吸塵器本體1時，限制塵埃容納部 5朝向與吸塵器本體1的底面或是放置了吸塵器本體1的面 呈垂直之方向的移位之機構。而，將塵埃容納部5裝著於 吸塵器本體1時，在過濾器15的凸部73被嵌合於吸塵器本 體1的壁面的凹部81之前，以使突起構件7〇的前端面的下 端抵接於凹陷部39的前側壁面地決定突起構件70的位置及 前端面的長度爲佳。藉此，使用者，在將塵埃容納部5裝 -77- 201103484 著於吸麈器本體1時，首先將突起構件70抵接於凹陷部39 ，其後將塵埃容納部5壓入，則過濾器1 5的凸部73會嵌入 吸塵器本體1的壁面的凹部8 1，成爲塵埃容納部5裝著於吸 塵器本體1的狀態。因此，對於使用者而言，可平順地將 塵埃容納部5裝著於吸塵器本體1，又，亦可得到所謂已將 塵埃容納部5裝著於吸塵器本體1之感覺。又，藉由具備有 過濾器15的凸部73及吸塵器本體1的壁面的凹部81，在將 塵埃容納部5裝著於吸塵器本體1時，可防止塵埃容納部5 朝向與吸塵器本體1的底面或是放置了吸塵器本體1的面呈 垂直之方向位移，可保持塵埃容納部5及塵埃分離部4以及 吸塵器本體1的氣密性。 再者，如第22圖般從側面觀察時之入口管3的入口開 口的形成方向，相對於與吸塵器本體1的底面或是放置了 吸塵器本體1的面呈垂直之垂線呈傾斜角度d。相對於塵埃 分離部4的拉出方向亦傾斜大致角度d。相對於入口管3之 入口開口的上端的位置，入口管3之入口開口的下端的位 置，爲於後側（塵埃分離部4側）。例如，角度d，爲5度 〜10度之範圍內的預定角度。藉由使爲與塵埃分離部4一 體成形之入口管3的前端之入口開口傾斜角度d，塵埃分離 部4之從吸塵器本體1的裝卸會變得容易。 第23圖，爲從右側觀察本發明之實施例3的集塵裝置2 之斷面圖。特別是顯示塵埃分離部4與塵埃容納部5抵接之 狀態。集塵裝置2的軸心，爲入口管3的軸心且爲外筒6的 軸心且爲內筒7的軸心且爲前蓋1 1的軸心。相對於軸心的 -78- ⑧ 201103484 形成方向（軸方向），塵埃分離部4的軸方向一端面與軸 方向另一端面、前蓋11的軸方向一端面與軸方向另一端面 、塵埃容納部5的一端面，爲大致垂直地形成。 集塵裝置2的軸心，相對於與吸塵器本體1的底面或是 放置了吸塵器本體1的面呈垂直之垂線，呈傾斜角度a。例 如，角度a，爲40度〜45度之範圍內的預定角度。不過’ 角度a，亦可設定得比40度還小。因此，塵埃分離部4的軸 方向一端面與軸方向另一端面、前蓋11的軸方向一端面與 軸方向另一端面、塵埃容納部5的一端面，相對於吸塵器 本體1的底面或是放置了吸塵器本體1的面會傾斜角度3。 如第2 3圖般從側面觀察時，凹陷部3 9 ’由前方起，依 序爲由相對於吸塵器本體1的底面或是放置了吸塵器本體1 的面爲呈大致垂直之前側壁面、大致平行於塵埃分離部4 的軸方向另一端面之底面’大致垂直於塵埃分離部4的軸 方向另一端面之後側壁面所構成。在裝著塵埃容納部5時 ，突起構件7 〇的前端面’爲抵接於凹陷部3 9的前側壁面。 突起構件70的前端面爲與凹陷部39的前側壁面相向’不過 突起構件70的前端面，因相對於吸塵器本體1的底面或是 放置了吸塵器本體1的面呈傾斜角度c ’故相對於凹陷部3 9 的前側壁面亦會變得傾斜大致角度c。於電動送風機28之 停止中，突起構件7〇的前端面與凹陷部39的前側壁面可抵 接，亦可不抵接而有稍微之間隙。當電動送風機2 8動作而 塵埃分離部4被朝向塵埃容納部5拉近時’則凹陷部39的前 側壁面會抵接於突起構件7 0的前端面’限制塵埃分離部4 -79- 201103484 朝向塵埃容納部5移位，抑制墊片9被擠壓變形爲佳。又， 代替將突起構件70形成於前蓋11，將凹陷部39形成於內筒 7，亦可將凹陷部39形成於前蓋1 1，將突起構件70形成於 內筒7。 第24圖，爲從前側觀察本發明之實施例3的塵埃容納 部5之正面圖。於前蓋11的左上側，形成有可目視被壓縮 之塵埃的蓄積量之透明或半透明的窗74。於窗74，描繪有 垃圾丟棄線，可通知使用者垃圾丟棄的時候。在對應於前 蓋1 1之軸方向一端面（前面）的下側之特別是朝向外延部 3 4的背面側的下部突出之螺絲凸塊（螺絲部67所形成的突 起）的位置，形成有用以接受朝向外延部34的背面側的下 部突出之螺絲凸塊（螺絲部67所形成的突起）之螺絲凸塊 接受部7 5。於塵埃分離部4與塵埃容納部5抵接時，藉由外 延部34的螺絲凸塊插入前蓋1 1的螺絲凸塊接受部75內，可 限制塵埃分離部4與塵埃容納部5相對性之移位。藉由外延 部3 4的螺絲凸塊及前蓋1 1的螺絲凸塊接受部75，而實現了 限制機構。 於前蓋11之軸方向一端面的最外周部，亦即對應於外 延部34之背面側的唇部68之位置’形成有用以接受外延部 34之背面側的唇部68之墊片承受面76。墊片承受面76，爲 至少包含比唇部68的寬幅還廣的圓環狀部，爲了易於接受 唇部68，該圓環狀部以由平面形成爲佳。於前蓋11之軸方 向一端面的內周側，亦即對應於外延部3 4的背面側的唇部 69之位置，形成有用以接受外延部34的背面側的唇部69之 -80- 201103484 墊片承受面77。墊片承受面77，爲至少包含比唇部69的寬 幅還廣的圓環狀部，爲了易於接受唇部69’該圓環狀部由 平面形成。藉由唇部68及墊片承受面76，而實現了外側的 密封機構（密封構件），藉由唇部69及墊片承受面77 ’而 實現了內側的密封機構（密封構件）。然後’突起構件70 ，爲形成於墊片承受面77之更內周側的上側。此爲’爲了 使其對應於形成在外延部34的背面側且爲內筒7的內周側 的凹陷部39的位置之故。又，突起構件7〇’爲由朝向左右 方向並列的2個突起構件7 0所構成。如此藉由使其朝向左 右方向具有寬幅，在突起構件70的前端面抵接於凹陷部39 的前側壁面時，安定性會增加。不過，突起構件7 0 ’亦可 由1個突起構件7〇所構成。又，亦可形成於墊片受部77的 外周且爲墊片受部7 6的內周處。 第25圖，爲從左後側觀察本發明之實施例3的塵埃容 納部5之立體圖。第26圖，爲從與軸方向另一端相向之吸 塵器本體1的後側壁面（電動送風機的前方壁面）的前側 觀察本發明之實施例3的塵埃容納部5之正面圖。過濾器1 5 ，爲於斷面形狀呈大致四角形的框體78內形成有過濾器構 件79。凸部73，爲形成於過濾器15的框體78之下部的左右 2處。凹部81，爲形成於吸塵器本體1的後側壁面（電動送 風機28的前方壁面）中與過濾器15的框體78相向之位置的 下部之左右2處。又，於過濾器15形成有凸部73，代替形 成於吸塵器本體1的後側壁面之凹部8 1 ’於過濾器1 5形成 凹部81，亦可於吸塵器本體1的後側壁面形成凸部73。 -81 - 201103484 於第26圖，輔助過濾器26(吸氣導管27的入口開口） ，爲於吸塵器本體1的後側壁面中靠近左側地形成。於吸 塵器本體1的後側壁面的上側，形成有收納除塵裝置24之 容納部8 2。於吸塵器本體1的後側壁面的最外周部，亦即 對應於墊片25的之位置，形成有用以接受墊片25的墊片承 受面80»墊片承受面80，爲至少包含比墊片25的寬幅還廣 之大致四角形部，爲了易於接受墊片25，該大致四角形部 以由平面形成爲佳。墊片承受面80，比起輔助過濾器26或 容納部82所形成的面，爲更朝向吸塵器本體1的前側突出 形成。從側面觀察時之墊片承受面80的形成方向，爲了能 沿著墊片25的後端面的形成方向，相對於與吸塵器本體1 的底面或是放置了吸塵器本體1的面呈垂直之垂線，呈傾 斜角度b。因此，墊片承受面80，相對於形成有輔助過濾 器26或容納部82的面，亦呈傾斜角度b。相對於墊片承受 面80之上端的位置，墊片承受面80之下端的位置，爲於前 側（塵埃容納部5側）。藉由墊片2 5及墊片承受面8 0，而 實現了密封機構（密封構件）。 第27圖，爲從前側觀察本發明之實施例3的塵埃分離 部4時之正面圖。突起構件72，爲形成於比塵埃分離部4之 軸方向一端面的外側之入口管3更上側。於左右方向，突 起構件72，爲形成於塵埃分離部4的中.央部。突起構件72 ，爲朝向左右方向具有寬幅地形成。不過，突起構件72, 亦可由朝向左右方向平行配置之複數個突起構件72所構成 。又，第27圖中的虛線，爲顯示形成於外筒6的內面之階 ⑧ -82- 201103484 段差。 第28圖，爲本發明之實施例3的塵埃分離部4之側面圖 及吸塵器本體1的前側之橫斷面圖。形成於塵埃分離部4的 突起構件72，爲朝向塵埃分離部4的軸方向延伸，亦即朝 向吸塵器本體1的前側壁面延伸形成，於該前端部具備有 凸部。亦即，突起構件72，具備有爪形狀或L字型狀。另 一方面，在對應於吸塵器本體1的前側壁面的突起構件72 之位置，形成有用以接受突起構件72的卡合孔82。藉由突 起構件72及卡合孔82而實現了卡合機構（卡合構件71 )或 限制分離之機構。使用者，在將塵埃分離部4裝著於吸塵 器本體1時，首先將突起構件72插入卡合孔82，其後，將 入口管3的入口開口端抵接於安裝在吸塵器本體1的墊片22 ，其後，只要將塵埃分離部4的軸方向另一端的下部，壓 接於卡合構件71即可。若電動送風機28動作而產生吸引力 時，塵埃分離部4會欲從吸塵器本體1浮起，不過突起構件 72的前端部的凸部，會抵接於卡合孔82的內側壁面並卡住 ，可抑制塵埃分離部4的軸方向一端從吸塵器本體1的前側 壁面移位或分離。因此，也防止了入口管3的軸方向一端 從墊片22移位或分離，而抑制了吸引力的降低或噪音的產 生。 代替於塵埃分離部4形成突起構件72，於吸塵器本體1 的前側壁面形成卡合孔82者，亦可於吸塵器本體1的前側 壁面形成突起構件72，於塵埃分離部4形成卡合孔82。突 起構件72的形成位置，可爲塵埃分離部4的軸方向一端面 -83- 201103484 亦可爲靠近上端之側，亦可比入口管3下側。又，代替突 起構件72，亦可將用以壓緊塵埃分離部4之軸方向前端的 上端面之押壓構件形成於吸塵器本體1的前側，亦可將用 以壓緊住入口管3的上端面之押壓構件形成於吸塵器本體i 的前側。 〔實施例4〕 將實施例1的塵埃容納部5的詳細，作爲實施例4予以 說明。 本發明之實施例4的電氣吸塵器，其特徵爲：可將通 氣構件（例如：集塵盒1 2 )，從內包於通氣構件會外殼的 第1狀態朝向外殼的前方方向轉動至通氣構件的開口面與 水平方向的形成角度（例如：角度e -角度f)成爲45度以 內的預定角度之第2狀態爲止。又或，本發明，爲可將通 氣構件（例如：集塵盒12)從內包於通氣構件或外殼的第 1狀態，朝向外殼的前方方向轉動至通氣構件的開口面與 把手的形成方向之形成角度（例如：角度e-角度f 一角度 h)成爲45度以內之預定角度的第2狀態爲止。而，根據本 發明，藉由可將通氣構件朝向外殼的前方方向轉動至通氣 構件的開口面與水平方向的形成角度成爲45度以內的預定 角度之第2狀態爲止，或是藉由可將通氣構件朝向外殻的 前方方向轉動至通氣構件的開口面與把手的形成方向之形 成角度成爲45度以內的預定角度之第2狀態爲止’使用者 可容易地排出蓄積於通氣構件內之塵埃。 -84 - ⑧ 201103484 又或，本發明之實施例4的電氣吸塵器，其特徵爲： 把用以將通氣構件（例如：集塵盒1 2 )安裝於外殼的安裝 構件，從側面觀察集塵部（例如：塵埃容納部5 )時，相 對於集塵部的後端面的形成方向或是相對於與吸塵器本體· 的底面呈垂直之垂線爲傾斜地固定於外殼內。而，根據本 發明，藉由把用以將通氣構件安裝於外殼的安裝構件，從 側面觀察集塵部時，相對於集塵部的後端面的形成方向或 是相對於與吸麈器本體的底面呈垂直之垂線爲傾斜地形成 ，不用將集塵部的前後方向作長，即可提昇將集塵部安裝 於外殻的機構之強度，又可抑制外殼的撓彎。 第29圖，爲從軸方向前端側觀察本發明之實施例4的 塵埃容納部之正面圖。特別是顯示除了前蓋1 1外之狀態。 與第6圖爲相同，相對於第6圖，第29圖爲顯示在集塵盒12 內之氣流62，及在集麈盒12內之塵埃83的蓄積狀態。 如第26圖所示般，吸氣導管27的入口開口，爲於吸塵 器本體1的左右方向中，靠近左側地形成。又，如第5圖（ B )所示般，外側流路3 5的出口開口，爲形成於比前蓋1 1 的上下方向中心線更上側，具備有在左右方向對稱之形狀 。又，如第10圖所般，在內筒7的外周側迴旋過之氣流62 ，爲在圓周方向（迴旋方向）流入外側流路35，並藉由下 游側壁面65而轉向朝軸方向。但是即使藉由下游側壁面65 轉向朝軸方向，於氣流62仍殘留有圓周方向（迴旋方向） 的成分，故氣流62 ’爲在外側流路3 5的塵埃分離部4的軸 方向另一端部分（外側流路3 5的中間部分）、在前蓋1 1的 -85- 201103484 軸方向一端部分（外側流路3 5的中間部分）也朝向軸方向 且朝向圓周方向，在前蓋11的軸方向另一端部分（外側流 路35的出口部分）也朝向軸方向且朝向圓周方向。亦即， 如第29圖所示，氣流62，在集塵盒12內的入口開口部，不 僅軸方向也朝向半圈順時針的圓周方向。因此，於集塵盒 12內之氣流62，不僅只直接被朝向過濾器15吸入，亦衝撞 於與圓周方向左向相向之集塵盒12的左側壁面，再衝撞於 集塵盒12的底面。衝撞於集塵盒12的底面之氣流62，再衝 撞於集塵盒12的右側壁面，在朝向集塵盒12的入口開口亦 即前蓋11的軸方向另一端面迴旋過後，而與流入集塵盒12 內之最初的氣流62合流。因此，於流入集塵盒12內的空氣 ，會在集塵盒1 2內，產生依近身側、左、遠身側、右、近 身側之順迴旋的氣流6 2 (從上面看塵埃容納部5時，爲順 時針方向之迴旋）》特別是於集麈盒12形成有網目構件時 ，氣流62的衝撞或迴旋更顯著。不過，由於集塵盒12的底 面及上下左右的側壁面以可通氣之方式呈開口，故也產生 了從集塵盒12的底面及上下左右的側壁面朝向集塵盒12外 的空氣流。此時，由集塵盒1 2的底面及上側壁面以及右側 壁面所形成之集塵盒12的右上部分，由於其氣流62的迴旋 力很強，故含於空氣的塵埃，爲藉由迴旋流所引起之離心 分離作用，被朝向迴旋流的外周側甩飛，而蓄積於集塵盒 12的右上部分。亦即，塵埃，爲從集塵盒12的右上部分漸 漸地蓄積起來。因此，也不管吸氣導管27的入口開口爲靠 左側存在，塵埃83爲從右側蓄積，故即使於集塵盒12內蓄 -86- 201103484 積塵埃83’亦不易妨礙迴旋流的產生，又對應於吸氣導管 2的入口開口之部分不易被塵埃83堵塞，故伴隨塵埃83的 蓄積因起之空氣的能量損失受到抑制，可抑制伴隨塵埃8 3 的蓄積引起之吸引力的降低。又，於塵埃8 3從集塵盒1 2的 右上部分蓄積起來時，由於也有從集塵盒12的底面及上下 左右的側壁面朝向集塵盒12外的空氣流，故集塵盒12的底 面及上下左右的側壁面，塵埃亦多少會附著其上。 第3 0圖，爲從側面觀察本發明之實施例4的塵埃容納 部之斷面圖。特別是顯示相對於外殼1 0，前蓋1 1爲閉合狀 態。外側流路3 5，爲在超過了前蓋1 1的軸方向一端面之前 蓋1 1內的位置，突然放大。再者，在超過了外側流路3 5的 前蓋Π的軸方向另一端面（外側流路3 5的出口開口）之集 塵盒12內的位置，亦突然放大。因此，氣流62，爲在超過 了前蓋11的軸方向一端面之前蓋11內的位置突然變慢並擴 散，再者，在超過了前蓋11的軸方向另一端面（出口開口 )之集塵盒1 2內的位置亦突然變慢並擴散。 又，集塵盒的底部84的上端及下端爲非對稱。具體上 ，集塵盒的底部84的上端亦即集塵盒13的底面與上側壁面 的接合部分，相較於集塵盒的底部84的下端亦即集塵盒13 的底面與下側壁面的接合部分，爲將曲率半徑設定得較大 ，而平緩地形成。集塵盒1 2的軸方向，由於相對於過濾器 15的軸方向呈傾斜角度a，故集塵盒的底部84的下端，於 集塵盒13中爲最近接過濾器I5。在將於前蓋11的軸方向一 端面之外側流路3 5的開口之上下方向的中心點及過濾器15 -87- 201103484 的軸方向一端面（入口面）之上下方向的中心點予以連結 之直線（線分）上’大致位有集塵盒的底部8 4的下端。而 ，流入集塵盒1 2內的氣流62，爲朝向過濾器1 5，並在從外 側流路3 5的出口開口出來的位置擴散，一部分爲沿著集塵 盒12的上側壁面朝向集塵盒的底部84，其他的一部分爲衝 撞於集塵盒的底部84並沿著集塵盒12的下側壁面朝向集塵 盒12的入口開口迴旋。由於集塵盒12的上側壁面，爲沿著 過濾器15朝向氣流62的方向形成，故易於朝向集塵盒的底 部8 4流動，另一方面，由於集塵盒12的下側壁面，爲與朝 向過濾器15之氣流62的方向相向形成，故空氣流易於停留 。集塵盒12的上側壁面，爲位於集塵盒12下側壁面之上游 側，又，由於迴旋力強，故塵埃83，爲從集塵盒12中之底 部84的上端蓄積起來。又，於集塵盒的底部84的上端之外 側，爲具備有限制集塵盒1 2朝向外殼1 0的前側彈出之突起 構件8 7。突起構件8 7，係以朝向其爲集塵盒1 2的旋動支點 的軸1 4作爲中心之圓的半徑方向延伸形成爲佳。或，突起 構件87，以具備有沿著該半徑方向之面爲佳。 第30圖的放大圖，爲顯示對於集塵盒12的外殼10之支 持構造。第31圖，爲從後側觀察本發明之實施例4的塵埃 容納部5之後面圖。特別是顯示相對於外殼1 〇，將過濾器 15打開之狀態。如第30圖的放大圖所示，集塵盒12爲藉由 安裝構件8 5而安裝於外殼1 〇的內側。藉此，可抑制外殼1 0 的外觀損害。如第31圖所示，安裝構件85具備有大致四角 形，並於前後方向及左右方向具備有某程度的寬幅。於安 ⑧ -88- 201103484 裝構件85的左右方向的兩端，形成有突起部86。藉由將突 起部86嵌入外殼10的一部分（從外殼1〇的下表面之在外殻 1 〇內朝向斜向方向延伸形成的部分），而將安裝構件8 5固 定於外殻1 0。然後，於安裝構件8 5的前側支持軸1 4。於軸 1 4，亦可具備有在將集塵盒1 2朝向前蓋1 1側推出之方向作 用彈性力之螺旋彈簧。而，集塵盒1 2朝向前側彈出時，安 裝構件85會留在外殼10側，以軸14爲支點僅集塵盒12朝向 前側移位。在此，安裝構件8 5，相對於與吸塵器本體1的 底面或是放置了吸塵器本體1的面呈平行之方向及與吸塵 器本體1的底面或是放置了吸塵器本體1的面呈垂直之方向 ，或是相對於塵埃容納部5或外殼10的軸方向另一端面的 形成方向，爲朝向斜向方向地形成。安裝構件85，相對於 塵埃容納部5或是外殼1 0之軸方向一端面的形成方向，亦 可爲朝向大致垂直之方向形成。塵埃容納部5及外殼1 9， 從側面觀察之形狀爲大致倒三角形或是大致扇形，亦即相 較於上邊，下邊較短。於如此之塵埃容納部5，如專利文 獻3般將安裝構件朝水平方向形成時，塵埃容納部5的下邊 會變長，集塵裝置2的軸方向的長度也變長，吸塵器本體1 的前後方向的長度也變長。若將安裝構件8 5本身縮短時， 用以將安裝構件85固定於外殻10之強度不足。特別是於軸 14形成有螺旋彈簧時，由於對於安裝構件85螺旋彈簧的彈 性力會產生反作用力，故安裝構件85會變易於撓彎、損傷 。又，於集塵盒12彈出之狀態，亦於安裝構件85賦予以集 塵盒12的荷重，故會變得易於撓彎、損傷。在此，爲了將 -89- 201103484 安裝構件85作長（集塵盒12的軸方向長度之1/2以上）， 且，將塵埃容納部5的下邊作短，而將安裝構件8 5，朝向 與吸塵器本體1的底面或是放置了吸塵器本體1的面呈平行 之方向以及相對於與吸塵器本體1的底面或是放置了吸麈 器本體1的面呈垂直之方向，或是相對於塵埃容納部5或是 外殻10的軸方向另一端面的形成方向，爲斜向方向地形成 。於第31圖，使用者，藉由將安裝構件85之描繪有「壓」 的部分予以按壓，從外殼10連同安裝構件85—起將集塵盒 1 2卸取下來。 第3 2圖，爲從側面觀察本發明之實施例4的塵埃容納 部之斷面圖。特別是顯示相對於外殼1 0，前蓋1 1爲呈打開 ，集塵盒12朝向外殻10的前方方向彈出之狀態。如第23圖 所般，軸心相對於垂直方向呈傾斜角度a，前蓋1 1的軸方 向一端面及軸方向另一端面的形成方向以及外殻10之軸方 向一端面的形成方向，爲與軸方向呈垂直。因此，前蓋11 的軸方向一端面及軸方向另一端面的形成方向以及外殻10 之軸方向一端面的形成方向，相對於垂直方向（重力作用 方向）呈傾斜大致（180-a)度，相對於水平方向（與重 力作用方向呈垂直的方向）大致角度a傾斜。因此，外殻 10之軸方向一端面的形成方向，相對於水平方向呈傾斜角 度e，該角度e爲大致等於角度a。因此，例如，角度e，與 角度a同樣爲40度〜45度之範圍內的預定角度。前蓋11， 相對於外殻1 〇係以軸3 1爲支點從前方向朝向下側方向旋動 ，不過如第32圖所示般到前蓋11的軸方向一端面及軸方向 ⑧ -90- 201103484 另一端面的形成方向至少成爲大致垂直之方向爲止爲可開 口。前蓋11，相對於外殼10之軸方向一端面的形成方向， 爲可開口至少角度（e + 90 )度。前蓋1 1，相對於外殻1 0 之軸方向一端面的形成方向，以開口比角度（e + 90 )度 更大爲佳。又，相對於水平方向之面的形成方向的角度， 爲與相對於垂直方向之面的法線方向的角度相同。 集塵盒12,伴隨從外殼10的彈出，以形成於集塵盒的 底部84的中間的外側軸13爲支點分割成集塵盒的上半部88 及集塵盒的下半部89，集塵盒的上半部88及集麈盒的下半 部8 9爲相對性打開僅角度g。例如，角度g爲1 1 .5度左右。 形成於集塵盒的上半部8 8的外側之突起構件8 7 (集塵盒1 2 的一部分），爲抵接於外殼1 〇之軸方向一端面開口的內側 ’集塵盒1 2的彈出受到限制。藉由該限制，集塵盒的下半 部89的前側端面，相對於外殻1〇的軸方向一端面，最大爲 打開角度f。例如，角度f爲3 3度左右。又，集塵盒1 2的前 側端面（開口面）與底面爲大致平行。集塵盒的上半部8 8 的前側端面，相對於外殼1 0的軸方向一端面，最大爲打開 角度（f_g)。又，集塵盒的下半部89的前側端面，相對 於水平方向，爲打開至角度成爲（e — f)爲止。例如，角 度e設定爲40度，角度f設定爲33度時，則角度（e— f)成 爲7度左右。亦即，集塵盒的下半部89的前側端面，相對 於水平方向，爲近接至7度左右，集塵盒的上半部88的前 側端面，相對於水平方向，爲近接至（1 1 . 5 + 7 )= 1 8.5度 左右。因此’集塵盒的上半部88的前側端面以及集塵盒的 -91 - 201103484 下半部8 9的前側端面，會變得近於水平方向，亦即比水平 方向與垂直方向的中間之45度更近於水平方向，換言之， 集塵盒的上半部88的前側端面及集塵盒的下半部89的前側 端面的法線方向，爲近於垂直方向（重力作用方向），亦 即比水平方向與垂直方向的中間之45度更近於垂直方向， 故蓄積於集塵盒12之塵埃83會變得易於掉落下來。 把手1 6，是從塵埃容納部5的後端跨及於前側平緩地 傾斜。使用者，由於爲了打開前蓋1 1並操作形成在把手16 前方的按鈕1 7，所以會握持把手1 6的前側。雖要視塵埃容 納部5的重心位置而定，不過當使用者握持把手1 6的前側 時，由於把手1 6的前側呈傾斜，所以塵埃容納部5整體相 對於水平方向成爲稍微朝上傾斜。當使把手1 6之前側的形 成方向（接線方向），相對於水平方向傾斜角度h時，塵 埃容納部5整體相對於水平方向成爲朝上仰角度h。例如， 角度h爲12度左右。使用者握持把手16的前側來排出集塵 盒1 2內的塵埃8 3之情形時，集塵盒之下半部8 9的前側端面 ，相對於水平方向，爲角度（e-f+h)，例如，接近到 19度，集塵盒之上半部88的前側端面，相對於水平方向， 爲角度（e - f+ g + h )，例如，接近到30.5度左右。因此 ，即使使用者握持把手1 6的前側將集塵盒1 2內的塵埃8 3予 以排出之情形時，集塵盒之上半部8 8的前側端面及集塵盒 之下半部89的前側端面，係接近於水平方向，亦即由於是 比水平方向與垂直方向之中間的45度還要接近於水平方向 ，所以可以使集塵盒12所蓄積的塵埃83容易地落下。不過 ⑧ -92- 201103484 ，把手16從塵埃容納部5的後端跨及於前側平緩地傾斜並 不是必須的’也可以使把手1 6朝向水平方向筆直地形成。 第3 3圖，爲本發明之實施例4之塵埃容納部的側面圖 。於前蓋1 1的左上側，形成有：可以目視所壓縮之塵埃之 蓄積量的透明或是半透明的窗74。尤其是’外殻10爲不透 明之情形時，由於使用者無法目視塵埃8 3的蓄積量’所以 就必須有窗74。於窗74 ’畫有垃圾丟棄線90 ’可以讓使用 者知道垃圾丟棄的時期。垃圾丟棄線90的形成方向’是相 對於集塵盒12內之塵埃83的蓄積方向爲大致垂直的方向’ 亦即相對於朝向過濾器1 5之吸入方向爲大致垂直的方向’ 亦即相對於大致水平方向爲大致垂直的方向。又’垃圾丟 棄線90的形成位置，是使蓄積在集塵盒12內之塵埃83不會 從前蓋1 1之軸方向一端部的開口散落的位置，例如，是與 前蓋1 1之軸方向一端部之開口的下端相對應的位置。即使 外側流路35被塵埃所封閉時，由於內側流路36呈開口，所 以吸引力不會過於降低。因此，藉由將垃圾丟棄線90的形 成位置，設在使塵埃8 3不會從前蓋1 1的開口散落的位置， 就可以於集塵盒1 2內儘可能地蓄積塵埃，而減低使用者把 塵埃排出的次數，可以減輕使用者的負擔。不過，對於吸 引力的維持，予以優先考量之情形時，也可以將垃圾丟棄 線90的形成位置，設在後側且下側。對於窗74，也可以形 成在右側來取代其形成在前蓋1 1的左側，也可以形成在外 殼1 〇來取代其形成在前蓋1 1。 第34圖，是從本發明之實施例4之塵埃容納部的右側 -93- 201103484 所觀察的斷面圖。第34圖（a) ’是顯示集塵盒12的全開 狀態，且第3 4圖（a )，是顯示集塵盒1 2的半開狀態。如 在上述所說明過，突起構件87’是抵接於外殼1〇之軸方向 —端面開口的內側，用以限制集塵盒1 2的彈出’而成爲如 第34圖（a)般的全開狀態。 如第34圖（a)的放大圖所示，於集塵盒之上半部88 之上側的前側，具備有用以將集塵盒1 2維持於半開狀態的 突起構件91與突起構件92。突起構件91與突起構件92皆爲 三角形狀。突起構件91與突起構件92是朝向前後方向形成 直線狀，突起構件91係形成於前側，突起構件92係形成於 後側，於突起構件9 1與突起構件92之間具備有間隙（凹部 )。突起構件91與突起構件92之頂點的高度，是以集塵盒 之上半部88的上表面爲基準，以兩者相同、或是突起構件 92這邊較低爲佳。於第34圖（a)，突起構件91之左邊（ 前側面）的傾斜角，是比突起構件92之右邊（後側面）的 傾斜角還大爲佳。突起構件92之左邊（前側面）的傾斜角 ，是比突起構件92之右邊的傾斜角還大。突起構件92之左 邊的傾斜角，相對於底邊爲接近於90度（80度〜90度）爲 佳。突起構件9 1之右邊（後側面）的傾斜角，是比突起構 件9 1之左邊的傾斜角還大。 還有，集塵盒12朝向外殻10的前方彈出之情形時，由 於是藉由集塵盒I2的自重或是彈簧的彈推力而具有速度氣 勢，所以會使朝向外殼1 〇之軸方向一端面開口的內側突出 的端部93，滑越過突起構件91的左邊，然後飛越過突起構 ⑧ -94- 201103484 件9 1與突起構件92之間的間隙，而滑動在突起構件92的右 邊。因此，集塵盒12，不會成爲第34圖（b)所示的半開 狀態，而成爲全開狀態。另一方面’藉由使用者的操作’ 在將集塵盒1 2收納於外殼1 〇內之情形時，當使用者的按壓 力強時，端部93，便飛躍過突起構件91與突起構件92之間 的間隙，但當使用者的按壓力弱時’端部93，滑越過突起 構件92的右邊，並越過突起構件92的頂點，然後滑越過突 起構件92的左邊，而落在突起構件91與突起構件92之間的 間隙。此時，當使用者排除掉對集塵盒1 2的按壓力時’端 部93，便抵接於突起構件92的左邊’限制集塵盒I2朝向外 殼10的前方彈出（旋動），而成爲半開狀態。並且’從半 開狀態，使用者，藉由對前蓋1 1之軸方向一端面施加按壓 力，使前蓋11抵接於集塵盒12的前面，端部93，滑越過突 起構件9 1的右邊，越過突起構件9 1的頂點，然後滑越過突 起構件91的左邊，使集塵盒12成爲收納狀態，並且使前蓋 1 1成爲全閉狀態。不過，由於突起構件9 1的左邊亦具有傾 斜，所以即使前蓋1 1爲開放狀態下、或者，即使使用者沒 有按壓著集塵盒12,只要將集塵盒12的前面開口朝向上方 ，使端部93，抵接於突起構件9 1的左邊，就能夠維持集塵 盒1 2的收納狀態。藉此，使用者，可以容易地將集塵盒1 2 收納於外殼1 0內，前蓋1 1也容易關閉。 還有，使用者，於半開狀態中，將集塵盒1 2的前面開 口朝向上方，將纖維紙設定於集塵盒1 2的內側，從纖維紙 之上按壓集塵盒12的底面，然後將集塵盒12壓入於外殼1〇 -95- 201103484 內，在打開前蓋11的狀態下，可以將集塵盒12收納於外殼 1 〇內。使用者，然後，可以關閉前蓋1 1。藉此，使用者， 只要進行將集塵盒1 2收納於外殻1 0內的動作，由於將纖維 紙壓入至集塵盒1 2的底面爲止，所以可以將纖維紙緊貼於 集塵盒12的底面及上下左右的側壁面，確實地裝著。並且 ’只要可以將纖維紙緊貼地裝著於集塵盒12的底面及上下 左右的側壁面的話，在捕集塵埃時，就可以抑制纖維紙破 損之情事。 〔實施例5〕 以下，說明實施例1〜4之其他的實施例。 在實施例〗〜4中，是使墊片9外周部之軸方向底部側 端部爲朝向軸方向爲終端，相對於此，在實施例5中，是 使墊片9外周部之軸方向底部側端部爲朝向外周方向延伸 此點爲其特徵。又，相對於實施例1〜4，在實施例5中， 是於階段差追加肋條95此點爲其特徵。又，相對於實施例 1〜4，在實施例5中，是在內筒7的軸方向前端部追加定位

藉此’可以抑制塵埃阻塞第1集塵部及第2集塵部連通的流 路。 第35圖，是從右側觀察本發明之實施例5之內筒的斷 面圖。第35圖的放大圖，是顯示唇部68及墊片9之軸方向 ⑧ -98- 201103484 底部側端部的放大圖。 墊片9的外周部，是比唇部68更位於外周側的位置。 墊片9之外周側之軸方向底部側的端面，是比唇部68之軸 方向底部側的端面更位於軸方向前端側的位置。墊片9的 外周面，雖是朝向軸方向，不過在軸方向底部其外徑逐漸 擴大並相對於軸方向呈傾斜。內筒7在被插入到外筒6內時 ，該墊片9的外周面，爲抵接於外筒6的內周面。此時，墊 片9之外徑呈擴大之外周部的軸方向底部，會朝向半徑方 向按壓（壓迫）於外筒6的內面，而彈性變形，使墊片9之 外周部的軸方向底部與外筒6的內面緊貼，來確保內筒7與 外筒6的氣密。但是，只有半徑方向的緊貼，並無法充分 地確保氣密，仍有空氣洩漏，產生空氣的能量損失或是產 生噪音之虞。 在此，在實施例5中，如第3 5圖的放大部所示，是將 墊片9之外周部的軸方向底部，更朝向外周側延長，而形 成外延部94。藉此，墊片9之外周部的軸方向底部，若以 斷面來觀察，係具有大致呈L字型形狀。外延部94，以環 於墊片9 一周來形成爲佳。又，外延部94之半徑方向的寬 幅，是與外筒6的外壁厚度相同爲佳，不過即使比外筒6的

smaller. Fig. 9 is a front elevational view of the inner cylinder 7 of the second embodiment of the present invention as seen from the side of the cylindrical portion. The cylindrical portion of the inner cylinder 7 is composed of a hollow semi-cylindrical cylindrical portion 57 and a hollow trapezoidal conical trapezoidal conical portion 58. The cylindrical portion 57 is located on the front end side of the cylindrical portion of the inner cylinder 7, and the trapezoidal circular cone portion 58 is located on the bottom side of the cylindrical portion of the inner cylinder 7. The base of the trapezoidal conical portion 58 is joined to the inner peripheral end of the extension portion 34. By the trapezoidal conical portion 58, the joint portion between the cylindrical portion 57 and the extension portion 34 becomes gentler, and the generation of peeling or turbulent flow of the air flow can be suppressed, the energy loss of the intake air can be reduced, and noise can be suppressed. The inner cylinder 7 is preferably integrally formed by the extension portion 34 and the guide tube 38 (guide member), the cylindrical portion 57, and the trapezoidal conical portion 58. The cylindrical portion, if not constituted by the cylindrical portion 57 and the trapezoidal conical portion 58, may be composed only of the cylindrical portion 57 or only the trapezoidal conical portion 58. That is, the cylindrical portion 57 may have a cylindrical shape or a conical trapezoidal shape. R1 is the outer shape radius of the cylindrical portion 57, R2 is the outer shape radius of the trapezoidal conical portion 58, R3 is the outer shape radius of the extension portion 34, and R4 is the outer radius of the guide tube 38. The outer shape of the extension portion 34 is substantially true. The semicircle of the cylindrical portion 57 is substantially round. The extension portion 34 and the cylindrical portion 57 and the trapezoidal conical portion 58 are formed on the concentric axis and are R1 <R2 <R3 relationship. For example, R1 is about 3 cm, R2 is about 5 cm, and R3 is about 6.5 cm. The axis of the guide tube 38 is opposite to the axis of the cylindrical portion 57, and is located at the deviation from the left side in Fig. 9 as R1. <R4 <R2 relationship. For example, R4 is about 4 cm. One end of the cylindrical portion 57 in the circumferential direction (the lower side of Fig. 9) is the terminal end, and the other end (the upper side of Fig. 9) of -54- 8 201103484 is joined to the guide tube 38. The side wall of the guide tube 38, from the other end of the cylindrical portion 57 to the front surface of the guide tube end portion 59, has a radius of curvature R4 and is gently curved in a semicircular shape, and the side wall of the guide tube end portion 59 is also outside the cylindrical portion 57. The outer circumference along the outer circumference of the cylindrical portion 57 (along the outer circumference of the trapezoidal conical portion 58) is gently curved. That is, the guide tube 38 has one end connected to the opening of the recessed portion 8 and the other end facing in the outer direction of the cylindrical portion 57 at the outer side of the cylindrical portion 57 (along the outer circumference of the trapezoidal conical portion 58) Direction), during which it is turned to 180° and is gently curved in a substantially semicircular shape. The recessed portion 8 itself has no step difference from the side wall of the recessed portion 8 toward the center of the bottom portion, and it is preferable to form a spherical shape smoothly, and the joint portion from the recessed portion 8 to the guide tube 38 is preferably formed without a stage difference. . Thereby, the energy loss of the intake air can be reduced, and the noise can be suppressed. The thickness D1 of the cylindrical portion 57 (between the outer shape R1 and the side wall of the recessed portion 8) is about 3 mm, and the inner side of the thickness D1 of about 3 mm is hollow, and the space communicates with the through hole 33. One end portion of the cylindrical portion 57 is thicker because it forms an inner wall for diverting the air flow to a flow path of substantially 180 degrees, so that noise can be reduced. Here, the thickness D with respect to the cylindrical portion 57 is about 13 mm, and the thickness of one end portion of the cylindrical portion 57 is about 6 mm, which is preferably thicker. That is, it is preferable to set the radius of curvature of one end portion of the cylindrical portion 57 to about 3 mm. This can reduce noise. Further, when the thickness D1 of the cylindrical portion 57 is also made thick, since the dust is easily clogged, the thickness D1 of the cylindrical portion 57 is preferably about 3 mm. The radius (R1 - D1) of the depressed portion 8 is preferably equal to or slightly larger than the inner radius of the outlet opening of the inlet pipe 3 (-55x 201103484). When the radius of the recessed portion 8 is smaller than the inner diameter of the outlet opening of the inlet pipe 3, the dust is clogged or the energy loss of the air is increased, so that the noise is increased. The through hole 33 is not formed in the trapezoidal conical portion 58 or the guide tube 38, and is preferably formed only on the outer peripheral surface of the cylindrical portion 57. However, the through hole 3 3 may be formed not only on the outer peripheral surface of the cylindrical portion 57 but also in the trapezoidal conical portion 58 or the guide tube 38. The diameter of the through hole 33 may be about 2 mm. When the diameter of the through hole 33 is set to about 2 mm, the number of the through holes 33 is preferably about 100. The guide pipe end portion 59, which is a part of the guide pipe 38, is provided in a radial direction from the circumferential bottom portion 60 of the guide pipe end portion 59 toward the circumferential end portion 61 of the guide pipe end portion 59. <" font. As shown in Fig. 9, the guide tube end portion 59 and the cylindrical portion 57' are repeated as viewed in the radial direction. By the end of the guide tube 38 (the guide tube end portion 59) extending to a position overlapping with one end of the cylindrical portion 57, a sufficient swirling force can be imparted to the sucked air. The one end opening (the opening of the upper portion of the extension portion 34) of the outer flow path 35 is formed on the opposite side (the opposite side of the 180 degrees side) from the guide pipe end portion 59 to the circumferential direction of the guide pipe end portion 59. It may be formed between at least one end of the guide tube end portion 59 to the outer flow path 35. Since the dust flows easily in the outer flow path 35, the length in the circumferential direction of the one end of the outer flow path 35 is longer. The downstream side wall surface 65 (left wall surface) which is open at one end of the outer flow path 35 is preferable. It is higher than the upstream side wall surface 66 (right wall surface). The downstream wall surface 65' is inclined from the inner circumferential side toward the outer circumferential side when viewed from the axial direction or curved. The outer circumferential side is more toward the upstream side than the inner circumferential side - 56 - 201103484. The wall 6 is longer in the circumferential direction. In this case, if the length of the garbage such as hair or cotton wadding is stuck to the downstream side wall surface 65, the force of guiding the garbage toward the inner peripheral side can be exerted by making the outer peripheral side long in the circumferential direction, which is slow. The mixture is slowly disintegrated, and the garbage is received by the dust accommodating portion 5. In order to prevent the dust accumulated in the dust containing portion 5 from being scattered from the other end opening of the outer side flow path 35 of the front cover 11, it is preferable that one end of the outer flow path 35 is opened to be disposed on the upper side. Here, when the centrifugal separation distance is to be made longer, the position at which one end of the outer flow path 35 is opened can be kept constant, and the position at which the opening of the depressed portion 8 is formed and the position at which the guide tube end portion 59 is formed can be made. The position in the clockwise direction and close to the opening of one end of the outer flow path 35 may be a position on the left side in Fig. 9. Fig. 10 is a front elevational view of the inner cylinder 7 of the second embodiment of the present invention as seen from the side of the cylindrical portion. The arrow in Figure 1 shows the direction of flow of the intake air. The air that flows in the direction of the substantially axial direction in the recessed portion 8 is turned by the recessed portion 8 in the radial direction 'turned in the circumferential direction by the guide tube 38'. Approximately half a week between the inner cylinder 7 and the outer cylinder 6 (i.e., from the guide) The tube end portion 59 to the one end of the outer flow path 35 is opened (circular) in the circumferential direction and the axial direction, and most of the inflowing air is opened to the one end of the outer flow path 35 (the air flow 64). Therefore, the recessed portion 8 and the guide tube 38' have a function of swirling the air flowing in the substantially axial direction. A part of the air flowing (rotated) in the circumferential direction and the axial direction between about half of the circumference between the inner cylinder 7 and the outer cylinder 6 (that is, the one end from the guide pipe end portion 59 to the one end of the outer flow path 35) is the through hole 33. It flows into the inner cylinder 7 (airflow 63). Further, the air that does not flow to the one end of the outer flow path 35 is half-57-201103484 weeks between the guide tube 38 and the outer tube 6 (that is, from one end of the outer flow path 35 to the end of the guide tube) The portion 5 9 ) flows toward the circumferential direction (the air flow 64 ) and merges with the air emerging from the guide tube 38 . In the second embodiment of the present invention, since the air swirling on the outer side of the inner cylinder 7 passes through the outer flow path 35 and flows into the dust accommodation portion 5 connected to the electric blower 28, it is not necessary to increase the centrifugal separation distance as long as half a week. Just left and right. Therefore, the height of the inner cylinder 7 and the length of the dust separating portion 4 in the axial direction can be shortened, and the length of the dust collecting device 2 in the axial direction can be shortened, so that the cleaner body 1 can be made smaller. The outer diameter ' of the dust separating portion 4 is approximately equal to the outer diameter of the inner cylinder 7, that is, the outer diameter 2R3 of the outer portion 34. The axial length (excluding the inlet pipe 3)' of the dust separating portion 4 is substantially equal to the axial height H5 of the inner cylinder 7. Then, with H5 <2R3 relationship. Therefore, the height of the dust separating portion 4 in the axial direction is smaller than the upper and lower width or the left and right width of the dust separating portion 4. For example, 2R3 is about 13 cm' and H5 is about 7 cm. The flow rate of the air (the air flow 62) that is opened at one end of the outer flow path 35 as the flow rate V 1 'flow into the inner cylinder 7 from the through hole 33 is the flow rate V2, and does not flow into the outer flow path 35. When the flow rate of the air (air flow 64) of the end opening is the flow rate V3, the relationship of V1 > V2 > V3 is provided. Further, the flow rate at the guide pipe 38 is higher than that at the inlet pipe 3, and the flow velocity at the outer flow path 35 is higher than the flow rate at the guide pipe 38. That is, the 1 airflow 62' is accelerated in the guide tube 38, and the acceleration is also accelerated in the outer flow path. Therefore, 'the flow path section of the guide pipe 38 is smaller than the flow path section of the inlet pipe 3', and the flow path section of the outer flow path 35 is smaller than that of the guide pipe 38. The flow path width w' in the radial direction is relative to the flow path width W1 at the end portion of the guide tube 38-201103484 terminal portion 59, and the flow path width W2 at the position from the guide tube 38 is The opening is fixed from the outlet of the guide pipe end portion 59 to the one end of the outer flow path 35 (the flow path width W2), and is opened from one end of the outer flow path 35 to the guide pipe end portion 59. The flow path width W2 is gradually narrowed to the flow path width W3, and the flow path width portion W3 is formed at the guide pipe end portion 59. Therefore, if the relationship W2 > W1 > W3 is too small, the dust may be clogged. Therefore, for example, W3 is about 1.0 cm. For example, \72 is 113-111 and is 4 (; 111 or so. 1^1 is the stomach 2-1^3- (the thickness in the radial direction of the guide tube end portion 59), and is slightly smaller than 3 cm. 1 is a perspective view of the inner cylinder 7 of the second embodiment of the present invention as seen from the side of the cylindrical portion. The side wall of the guide pipe end portion 59 is not terminated perpendicularly to the circumferential direction, but is divided into two stages of buckling. approximately" The <" character is the terminal. Specifically, from the axial end portion of the guide tube end portion 59 to the intermediate portion in the axial direction, the angle is close to the perpendicular line perpendicular to the circumferential direction, and the axial direction of the guide tube end portion 59 to the end portion of the guide tube is terminated. The bottom of the root is terminated more obliquely than the perpendicular line perpendicular to the circumferential direction. For example, when the side wall of the guide pipe end portion 59 is at the position perpendicular to the circumferential direction at the position of the circumferential end 60 of the guide pipe end portion 59, a sufficient swirling force cannot be imparted, and dust cannot be sufficiently separated. On the other hand, when the position of the tip end portion 61 of the guide pipe end portion 59 in the circumferential direction is terminally perpendicular to the circumferential direction, the swirling force is excessively strong, and the air flowing into the outer channel 35 in the first week of the swirling is When the dust is reduced, the dust cannot be sucked into the dust separating portion 4 by the outer flow path 35 (especially the dust having a large specific gravity). In particular, in the present invention, since the inlet side of the dust separating portion 4 - 59 - 201103484 is located in the direction of gravity and the outlet side is in the direction of gravity, the dust cannot be sucked by the outer flow path 35, and thus is disposed in the dust separating portion 4 The situation of dust remaining is remarkable. Here, by making the guide tube terminal portion 59 substantially " The <" character is a terminal, and a sufficient swirling force can be imparted to the air flowing into the recessed portion 8. Further, since the air that has flowed into the recessed portion 8 flows toward the downstream side in the axial direction, the flow rate in the axial direction of the distal end side of the guide tube end portion 59 in the axial direction is observed when the guide tube end portion 59 is viewed. More (higher pressure). Here, the axial direction bottom end side is made longer in the circumferential direction than the axial end side of the guide tube end portion 59, and the axial direction bottom side of the guide tube end portion 59 having a large flow rate is Can give a full swing. Further, instead of the guide pipe end portion 59, it is made substantially " In the shape of the <"", the side wall of the guide pipe end portion 59 may be gradually inclined in the circumferential direction from the distal end side in the axial direction toward the bottom side in the axial direction, as shown in Fig. 2, which is viewed from the back side of the extension portion. A plan view of the inner cylinder 7 of the second embodiment of the present invention. Fig. 13 is a perspective view of the inner cylinder 7 of the second embodiment of the present invention as seen from the back side of the extension portion. The spacer 9 (sealing member) is attached to the back side of the extension portion 34 by means of three screws 67 (mounting members). The spacer 9 is provided with an annular lip portion 68 (projecting portion) on the outer peripheral side and an annular lip portion 69 (projecting portion) on the inner peripheral side. The lip portion 68 is provided to maintain the airtightness of the inner tube 7 and the front cover 11 located in the outer side flow path 35, and the lip portion 69 is for maintaining the gas of the inner tube 7 and the front cover 1 1 located in the inner side flow path 36. Set for confidentiality. Further, the lip portion 68 and the lip portion 69 are formed to extend from the inner peripheral side toward the outer peripheral side. Therefore, when the dust collecting portion 5 is attached to the dust collecting and separating portion 4, the lip portion 68 and the lip portion 69 abut against the front cover 1011 of the dust collecting portion 5, and are elastically deformed to maintain airtightness. Further, when the electric blower 28 is activated, when the suction force is generated, the dust collecting and separating portion 4 is attracted to the dust collecting portion 5, and the lip portion 68 and the lip portion 69 are more elastically deformed to maintain airtightness. Therefore, when the electric blower 28 is operated, the air-tightness holding force between the dust collecting chamber 5 and the dust collecting and separating unit 4 is increased as compared with the case where the electric blower 28 is stopped. However, it is preferable that the lip portion 69 is formed to extend from the outer peripheral side toward the inner peripheral side, and the lip portion 69 is formed to extend from the inner peripheral side toward the outer peripheral side, and the inner peripheral side portion 1 of the outer peripheral passage 35 is terminated. 00, dust or leakage from the outer flow path 35 is caught. By forming the lip portion 69 from the outer peripheral side toward the inner peripheral side, it is possible to suppress dust from being caught or leaking. Further, the spacer 9 includes the lip portion 68 and the lip portion 69, and is preferably integrally molded by an elastic material such as rubber. The substantially upper half of the inner peripheral side (the inner peripheral side of the lip portion 69) of the cylindrical portion is closed by a spacer 9 provided with a recessed portion 39 which is recessed toward the inner side in the axial direction of the cylindrical portion, and the cylindrical portion The substantially lower half of the inner peripheral side (the inner peripheral side of the lip portion 69) is open without being closed by the spacer 9. This opening forms the inner flow path 36. The spacer 9 may have the same area as the area of the closed portion, and the area of the opening portion may be the same or smaller. By making the area of the portion closed by the spacer 9 smaller than the area of the opening portion, the energy loss or noise of the air flowing through the inner side flow path 36 can be reduced. Fig. 14 is a side elevational view of the inner cylinder 7 of the second embodiment of the present invention as seen from the upper side. The downstream side wall surface 65 (left wall surface) at which one end of the outer flow path 35 is opened is higher than the upstream side wall surface 66 (right wall surface), and only the phase difference dH of the height is opened. Thereby, the flow on the outer side of the cylindrical portion can be smoothly changed toward the axial direction along the downstream side ζ -61 - 201103484 wall surface 65, and the dust contained in the swirling flow also flows toward the dust containing portion 5. The inner wall surface 101 of the outer flow path 35 is formed so that the downstream side wall surface 65 of the inlet of the outer flow path 35 faces the other end surface in the axial direction of the inner tube 7 which is the outlet of the outer portion 35, and is formed toward the circumference or curved. Thereby, the dust can flow smoothly in the outer side. Further, since the inner wall surface 110 of the outer flow path 35 is inclined or curved toward the air flow from the outer flow path 35, not only the component in the circumferential direction (the swirling component) but also the axial direction is formed. Fig. 15 is a plan view showing the second embodiment of the present invention as seen from the right side. The extension portion 34 is oriented toward the outer flow path 35 (the height from the lower side toward the axial direction is low. The surface of the extension portion 34 is formed in a spiral shape toward the outer side flow path 35 in the first circumference. If the cylindrical portion 57 is The height has a relationship of Η 1 > H2 when the height of the highest position of the trapezoidal conical portion 58 is H2. Further, when the highest position of the guide tube 38 is H3, the relationship of H3 > H1 is provided. It is only necessary to open at least one end of the guide tube end portion 59 to the outer flow path 35, and it may be formed on the side of the leading end portion 59 as compared with the side of the outer flow path 35. On the side of the road 3 5, since the flow rate into the outer flow path 35 is larger than the flow rate of the inflow, it is meaningless to form the through hole 3 3 on the outer side. Fig. 6 is a view of the present invention viewed from the right side. The inner surface of the embodiment 2 has H4 if the depth of the deepest portion of the depressed portion 8 is in the axial direction. < H1 relationship. that is, The depth of the depressed portion 8 is also shallow at the height of the cylindrical portion 57. From a stereo perspective, The sag becomes easy, To bend from the side flow path to the inclined flow path 3 5 , Therefore, Also on the side of 5 7 upper side) * for the Chao as H1, Then the height of the joint is to be formed between the conduit end hole 3 3 way 3 5 side It is a half-62-201103484 spherical shape of β 8 and the sectional shape of the depressed portion 8 is As shown in Fig. 14, it is roughly semicircular. therefore, The depth H4 of the depressed portion 8, It is almost equal to the outer radius R 1 of the cylindrical portion 57 or the radius of the opening portion of the recessed portion 8. therefore, The formation position of the depressed portion 8 in the axial direction, The position in the axial direction of the through hole 33 is covered. If the depth H4 of the depressed portion 8 is too deep, Then, the flow rate of the air taken in from the through hole 33 is reduced. On the other hand, If the depth H4 of the depressed portion 8 is too shallow, Then, in the recessed portion 8, there is a clogging of dust. The ease of injection molding is also considered. The depressed portion 8 is preferably formed into a hemispherical shape. but, The depressed portion 8 is not limited to a hemispherical shape. It may also be an elliptical or deep elliptical shape that is shallower than a hemisphere. and, To guide one end of the bottom surface of the tube 38, The bottom surface of the recessed portion 8 is smoothly joined without a stage difference. The other end of the bottom surface of the guide tube 38, The surface of the extension portion 34 is smoothly joined without a step difference. Guide the bottom surface of the tube 38, From the one end of the bottom surface of the guide tube 38 to the other end of the bottom surface of the guide tube 38, it is preferable to gently slope without a step difference. also, Since there is a guide tube 3 8 from half of the hemispherical recess 8 Therefore, if the part of the guide tube 38 is removed, Actually, the depressed portion 8 is formed in a 1/4 sphere shape. And the air that swirls on the outside of the cylinder, It is discharged from the outer flow path 3 5 (air flow 6 2 ). The air which flows into the inside of the cylindrical portion from the through hole 3 3 is a space in the cylindrical portion and a space in the extension portion 34. Swinging in a small place, One side is discharged from the inner flow path 36 (air flow 63). The air flowing from the through hole 3 3 into the inner side of the cylindrical portion, Compared to the air swirling on the outer side of the cylindrical portion, Its energy loss is quite large, but, The dust does not accumulate in the dust containing portion 5, The flow rate of air flowing from the through hole 33 into the inner side of the cylindrical portion, Compared to the t-63-201103484 flow of air swirling on the outside of the cylindrical portion, For quite a few, Therefore, the overall energy loss is small. Figure 17 (a), A perspective view of the dust separating portion of the second embodiment of the present invention is viewed from the front. And Figure 17 (a), A side view of the dust separating portion of the second embodiment of the present invention is seen from the right side. The arrow ′ in Fig. 17 indicates the abutment range of the axial end portion of the cylindrical portion 57 and the outlet end portion of the inlet pipe 3. The axial end portion of the semicircular shape of the cylindrical portion 57, It is in contact with the outlet end of the inlet pipe 3. Looking at the problem of combined accuracy, The axial end portion of the cylindrical portion 57 and the outlet end portion of the inlet pipe 3 are not completely abutted. Even if there is a gap (less than 1 mm), it doesn't matter. However, If there is a gap, the air will leak. Energy loss will increase, The noise will also increase. therefore, When the axial end portion of the cylindrical portion 57 and the outlet end portion of the inlet pipe 3 are made airtight, Alternatively, the gasket (sealing member) may be interposed between the axial end portion of the cylindrical portion 57 and the outlet end portion of the inlet pipe 3, on the other hand, As shown in the enlarged view of the section, On the inner side of the axial end surface of the outer cylinder 7, The total length of the front end portion of the guide tube 38 in the axial direction, A step difference is formed along the axial direction front end portion of the guide tube 38. The thickness of the axial end surface of the outer cylinder 7 is taken as D2. When the thickness of the inner peripheral side of the portion of the leading end portion in the axial direction of the lead pipe 38 corresponding to the end surface of the outer tube 7 in the axial direction is D3, Then have D2> D3 relationship, Thus a phase difference of (D3 - D2) is produced. E.g, 02 is about 3mm, And D3 is about 2mm. therefore, Stage difference, It is about 1mm. therefore, The inner side of the axial end surface of the outer cylinder 7, The portion corresponding to the front end portion of the guide tube 38 in the axial direction is It is thin on the inner circumference side. And , As shown in the enlarged view of the section, The inner tube 6 and the outer tube 7 are combined so that the front end portion of the guide tube 38 in the axial direction abuts 8 - 64 - 201103484 in this stage. This stage is poor, Since the inner side of the axial end surface of the outer cylinder 7 and the front end portion of the guide pipe 38 in the axial direction are sealed, Therefore, by this stage difference, Can reduce the energy loss of the air, Or reduce noise. Poor processing accuracy or combination accuracy, Or running on the electric blower 28, The inner cylinder 7 is attracted toward the dust receiving portion 5 side, And the front end portion of the guide tube 38 in the axial direction, When not completely abutting the inner side of the axial end face of the outer cylinder 6, The stage difference also suppresses air leakage. The thickness of the leading end portion of the guide tube 38 in the axial direction, The thickness D1 of the front end portion of the cylindrical portion 57 in the axial direction is Because it is thinner, It is difficult to form a sealing member such as a gasket, Therefore, it is better to achieve the sealing function by the stage difference. also, Inlet pipe 3, It is preferable to form an integral body with the outer cylinder 6. On the inner circumferential surface (side wall surface) of the outer cylinder 7, And, Near the side of the axial end surface (upper surface) of the outer cylinder 7, And, Between the outlet opening of the guide tube 38 and the inlet opening of the outer flow path 35, Forming a rectifying plate 102 (ribs, wing). The formation position of the rectifying plate 102, It is also possible to be near the center between the outlet opening of the guide tube 38 and the inlet opening of the outer flow path 35. It is also possible to be closer to the outlet opening side of the guide tube 38 than the center. The rectifier plate 102 is plate-shaped, It is formed to extend in the circumferential direction. The length of the rectifying plate 102 in the circumferential direction, It is much smaller than the inlet opening from the outlet opening of the guide tube 38 to the outer flow path 35. As shown in Figure 17 (b), Forming direction of the rectifying plate 1 0 2 , It is a direction from the formation position of the rectifying plate 102 toward the inlet opening of the outer flow path 35. The rectifying plate 1〇2 can be 1 piece. It can also be a plurality of pieces. There is a large gap between the rectifying plate 102 and the extension portion 34. Of course, there is air flow in this large gap. There is also a small gap between the rectifying plate 1 0 2 and the inner side of the axial end surface of the outer cylinder 7 f* -65- 201103484, There is also air flow in this large gap. A small gap is formed between the inner sides of the end faces of the rectifying plate 102 and the outer tube 7 in the axial direction. Since the flow of air is formed on both sides of the rectifying plate 1 〇2, the rectifying plate 1 can be suppressed. The generation of turbulent flow at the downstream end of 2. And by the rectifying plate 102, The swirling flow can be directed toward the inlet opening of the outer flow path 35. Therefore, the air flowing in from the guide tube 38, Since it is not rotated for a few weeks in the outer cylinder 7, it is guided toward the outer flow path 35, Therefore, the energy loss of the air can be reduced. Again, It is not the inner peripheral side of the slower flow rate (the outer peripheral surface of the inner cylinder 7), Rather, it is formed on the outer peripheral side of the flow rate (the inner peripheral surface of the outer cylinder 6). Therefore, even if the shape of the rectifying plate 102 is small, There is also the effect of turning the swirling flow. Since the flow plate 1 02 can be reduced, Therefore, the turbulence of the air flow can be reduced to reduce the energy loss of the air. According to Embodiment 2 of the present invention, The recessed portion 8 is formed at the front end portion of the inner cylinder 7 to have a swirling function. The length of the axial direction of the dust collecting device 2 can be shortened, The cleaner body 1 can be made smaller.

Dotted arrow, The direction in which the dust accommodation portion 5 is pulled out is displayed. The direction of the dotted arrow, It is a surface opposite to the bottom surface of the cleaner body 1 or the vacuum cleaner body (for example: Floor surface) is vertical or slightly forward in the vertical direction (for example: 5 degrees) The one end of the inlet pipe 3 integrally formed in the dust separating portion 4 in the axial direction is abutting - 69 - 201103484 and is connected to the lower end of the other end of the spacer 22' in the axial direction of the dust separating portion 4, In order to be engaged by the engaging member 71 (fixing member), It is fixed to the vacuum cleaner body 1.

On the other hand, the dust accommodating portion 5 is attached to the cleaner body 1, One end of the dust receiving portion 5 in the axial direction, The spacer spacer 9 abuts against the other end of the dust separating portion 4 in the axial direction. The other end of the dust receiving portion 5 in the axial direction, Abutting the spacer spacer 25 against the cleaner body 1, The upper surface of the dust accommodating portion 5 is covered by the upper shroud 56 to the other portion of the dust accommodating portion 5, It is not in contact with the dust separating portion 4 or the cleaner body 1. that is, Dust housing 5, For one end and the other end in the axial direction, The dust separation unit 4 or the cleaner body 1 is supported upward in a state of being floated upward. therefore, user, Open the upper shield 56, Just hold the handle 16 and pull the dust receiving portion 5 toward the dotted arrow. And the dust separating portion 4 is still left in the cleaner body 1, Then, only the dust containing portion 5 can be removed from the cleaner body 1. that is, The dust accommodating portion 5 and the dust separating portion 4 can be detached from the cleaner body 1 independently. therefore, For the user, The removal of the accommodating portion 5 is easy. Most of the dust, Because it is accumulating, Compressed in the dust receiving portion 5, User, Even if the dust collecting device 2 is removed from the cleaner body 1 and the dust separating portion 4 and the dust containing portion 5 are separated, and the dust in the dust containing portion 5 is discharged, the so-called three-stage operation is performed. On the other hand, the dust separating unit 4 can be left in the cleaner body 1 to remove only the dust containing unit 5 from the cleaner body 1. And the so-called two-stage operation of discharging the dust in the dust accommodating portion 5, For the user of -70- 201103484, The dust discharge operation becomes easier. also, Handle 16, Since it is inclined from the rear end of the dust receiving portion 5 to the front side, Therefore, the user can pull the dust containing portion 5 in the vertical direction or in the direction slightly forward of the vertical direction. Furthermore, The dust accommodating portion 5 is supported by the dust separating portion 4 and the cleaner body 1 only by the spacer 9 and the spacer 25. The other portion of the dust containing portion 5 is in a state of being floated from the cleaner body 1. Therefore, when the electric blower 28 operates to generate an attraction, With this attraction, The dust accommodation portion 5 can face the dust separation portion 4 side and the rear side wall surface side of the cleaner body 1, The spacer 9 and the spacer 25 are displaced in the pressing direction. Therefore, the airtightness between the dust separating portion 4 and the dust containing portion 5 can be maintained. And the airtightness between the dust accommodating portion 5 and the cleaner body 1. Near the axis of one end of the dust accommodation portion 5 in the axial direction, A protruding member 70 for guiding or assisting the attachment and detachment of the dust receiving portion 5 is formed. Protrusion member 70, It is formed to protrude from the one end surface in the axial direction of the dust accommodation portion 5 toward the axial direction. Projection member 70, It is the same material as the front cover 1 1 And it is better to form the body with the front cover. It is not possible to form it in one piece. The front end surface of the protruding member 70, In order to face the direction of the pull-out, that is, with respect to the bottom surface of the sucker body 1 or the surface on which the cleaner body 1 is placed, In a direction that is substantially perpendicular or a direction that is slightly forward than the vertical direction (for example: The predetermined angle within the range of 〇 5 degrees is formed. The guiding mechanism is realized by the protruding member 7 and the recessed portion 39 of the dust separating portion 4. especially, When the user attaches the dust accommodating portion 5 to the cleaner body 1, the hand 16 of the dust accommodating portion 5 is first held. The front end surface of the protruding member 7A is brought into contact with the front side wall surface of the recessed portion 39 of the dust separating portion 4, Thereafter, the dust receiving portion 5 is pressed in, If the general -71 - 201103484 force can no longer be pressed in, Closing the upper shroud 56, Then, the dust accommodating portion 5 can be attached to the cleaner body 1. therefore, For the user, It is also easy to mount the dust accommodating portion 5. also, It is also possible that when the dust receiving portion 5 cannot be pressed into a specific position, The inner shape of the upper shroud 56 (the shape abutting against the surface of the dust accommodating portion 5) is formed so that the above-described shroud 56 cannot be closed. Figure 20, A side view of the vacuum cleaner body 1 of the third embodiment of the present invention is seen from the right side. Figure 2, A perspective view of the cleaner body 1 of the third embodiment of the present invention is viewed from the upper right side. In particular, after the dust accommodating portion 5 is removed from the cleaner body 1, The state in which the 分离 分离 separation unit 4 is pulled in the substantially upward direction. Dotted arrow, The direction in which the dust separating unit 4 is pulled out is displayed. The direction of the dotted arrow, With respect to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed, It is in a substantially vertical direction. Engaging member 7 1, Plate-shaped, The rear side is supported by the vacuum cleaner body 1 by the shaft. Furthermore, In such a manner that the front side of the engaging member 71 is pushed toward the side of the cleaner body 1, A spring is attached around the shaft or to the engaging member 71 itself. In a state in which the dust separating portion 4 is installed, The lower portion of the other end of the dust separating portion 4 is engaged with the front side of the engaging member 71, The dust separating portion 4 is fixed by the spring force of the spring without falling off. Dust separation unit 4, In addition to the lower portion of the inlet pipe 3 or the other end of the dust separating portion 4 in the axial direction, The bottom surface of the dust separating portion 4 can also be supported by the cleaner body 1. and, user, Just take one hand, Against the spring thrust of the spring, The engagement by the engaging member 71 is released, And with the other hand, Holding the inside or the outside of the recess 39, Pulling the dust separating portion 4 toward the direction of the dotted arrow, Then, the dust separating unit 4 can be removed from the cleaner body 1. Therefore -72- 201103484, user, The eliminator separation portion 4 can be easily removed from the cleaner body 1. When the dust separating unit 4 is attached to the cleaner body 1, The user's holding the inside or the outside of the recessed portion 39, First, one end of the inlet pipe 3 is abutted against the gasket 22, Thereafter, the dust separating portion 4 is pressed in, The front side of the engaging member 71 passes over the lower portion of one end of the dust separating portion 4 in the axial direction to achieve engagement. The 分离 分离 separating portion 4 can be attached to the cleaner body 1. therefore, The user's can easily attach the dust separating unit 4 to the cleaner body 1. also, The other end face of the dust receiving portion 5 in the axial direction, The rear side wall surface (the front wall surface of the electric blower 28) of the cleaner body 1 facing the other end in the axial direction of the dust accommodation portion 5 is formed almost across the front surface. However, if viewed from the front side of the vacuum cleaner body 1, Then the inlet opening of the suction duct 27 (auxiliary filter 26), It is formed close to the left side. also, The rear side wall surface of the cleaner body 1, It is formed in a direction substantially perpendicular to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed. Furthermore, Above the inlet pipe 3 on the outer side of the one end surface in the axial direction of the dust separating portion 4, A projecting member 72 (engagement member) for engaging the front end side of the dust separating portion 4 in the axial direction on the inner wall of the front side of the cleaner body 1 is formed. When the electric blower 28 operates to generate an attraction force, With this attraction, The dust receiving portion 5 is intended to be displaced toward the rear side. Furthermore, With this attraction, The dust separating unit 4 is also displaced toward the dust receiving portion 5 side in the axial direction of the dust collecting device 2, the result, The dust separating unit 4 is intended to float from the cleaner body 1. that is, The other end of the dust separating portion 4 in the axial direction, Because the engaged member 7 1 is engaged, Therefore, the displacement of the other end of the dust separating portion 4 in the axial direction is restricted. on the other hand, One end of the dust separating portion 4 in the axial direction, Since only one end of the axial direction of the mouth tube 3 of -73-201103484 is abutted against the slab 22, the displacement cannot be restricted. Therefore, it will be displaced or separated from the spacer 22, And can't keep air tight, Inducing a decrease in attractiveness, generates noise. here, With the protruding member 72, It is possible to prevent one end of the inlet pipe 3 from being displaced or separated from the gasket 22, Reduce the reduction of attraction or the generation of noise. Figure 22, A side view of the dust collecting device 2 of the third embodiment of the present invention is seen from the right side. In particular, the state in which the dust separating unit 4 and the dust containing unit 5 are separated is displayed. At the other end of the dust receiving portion 5 in the axial direction, A filter 15 is provided. Filter 15, A filter member 79 is formed in a frame 78 having a substantially quadrangular cross-sectional shape. Crossing the entire circumference of the outer circumference of the filter 15, A spacer 25 having a substantially quadrangular shape is formed. therefore, Shim 25, It is rotatable relative to the outer casing 1 with the filter 15. Shim 25, It is preferable that the hem is folded and contracted in the front-rear direction. and, When viewed from the side as shown in Figure 22, Shim 25, The ratio filter 15 is disposed closer to the casing 10 side. that is, For the ratio filter 1 5 , Further, it protrudes toward the outside of the spacer 25 (on the side of the electric blower 28). The direction in which the rear end surface of the filter 15 is formed when viewed from the side as shown in Fig. 22, With respect to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed, To be substantially vertical, And in the direction along the rear side wall surface of the cleaner body 1 (for example: parallel). on the other hand, The direction of formation of the rear end surface of the spacer 25 when viewed from the side as shown in Fig. 2 is inclined at an angle b with respect to the bottom surface of the cleaner body 1 or the perpendicular line of the surface on which the cleaner body 1 is placed. that is, The direction in which the rear end face of the spacer 25 is formed, The drawing direction with respect to the dust containing portion 5 is also inclined by a substantially angle b. therefore, The rear end of the spacer 25, The rear end face of the filter 8 - 74 - 201103484 1 5 is also inclined by an angle b. Relative to the position of the upper end of the end face after the spacer 25, The position ' of the lower end of the end face after the spacer 25 is the front side (the side of the outer casing 10). When viewed from the side as shown in Fig. 22, the position of the upper end of the end face after the spacer 25, It is substantially the same as the position of the upper end of the end face after the filter 15 However, the position ' of the lower end of the end face after the spacer 25 is located at the front side of the lower end of the rear end face of the filter 15. E.g, The angle b' is a predetermined angle in the range of 5 degrees to 10 degrees. Further, the rear side wall surface of the cleaner body 1 and the wall surface facing the spacer 25 are formed on the front side of the wall surface facing the filter 15. Further, relative to the position of the filter 15, The position ' relative to the position of the spacer 25 with respect to the wall surface of the cleaner body 1 facing the filter 15 with respect to the wall surface facing the spacer 25 is preferably on the front side. With this, When the user presses the dust accommodation portion 5, before the filter 15 abuts against the cleaner body 1, The gasket 25 is abutted against the cleaner body 1. Compared to the spacer 9 between the dust separating portion 4 and the dust receiving portion 5, The spacer 2 5 ' between the dust containing portion 5 and the cleaner body 1 is preferably made of a material having a low viscosity. this is, Compared to the direction in which the spacer 9 is formed, Due to the direction in which the spacer 25 is formed, Close to the drawing direction of the dust receiving portion 5, That is, with respect to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed, In a substantially vertical direction, Therefore, when the dust accommodating portion 5 is attached or detached from the cleaner body 1, a large shearing force is received. If the gasket 25 is highly viscous, When the dust accommodating portion 5 is attached or detached from the cleaner body 1, The gasket 25 will adhere to the gasket receiving surface 80, It takes a lot of effort to load and unload. here, Compared to the gasket 9, By making the viscosity of the spacer 25 lower, ϋ -75- 201103484 It is easy to attach and detach the dust accommodating portion 5 from the cleaner body 1. In order to make the adhesion of the spacer 25 lower than that of the spacer 9, The spacer 25 is formed of a material having a smaller elastic force than the spacer 9. In other words, The spacer 9 is made of a material having a larger elastic force than the spacer 25. The dust separating unit 4 is substantially fixed to the vacuum cleaner body 1 in a state of being fixed. The dust accommodating portion 5 is in a state of being floated from the cleaner body 1. Furthermore, Since it is compared to the position of the spacer 25, The position of the spacer 9 is far from the electric blower 28 on the flow path. Therefore, compared with the dust accommodating portion 5 and the cleaner body 1, The dust separating unit 4 and the dust containing unit 5 are relatively easily separated. By making the elastic force of the spacer 9 larger than the spacer 25, On the other hand, the elastic deformation of the spacer 9 allows the separation between the dust separating portion 4 and the 容纳 accommodating portion 5, The so-called other effect of maintaining the airtightness between the dust separating portion 4 and the dust containing portion 5 which are relatively easy to separate can be obtained. The direction in which the front end face of the protruding member 70 is viewed from the side as viewed in Fig. 22, The angle c is inclined with respect to a perpendicular line perpendicular to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed. The drawing direction with respect to the dust containing portion 5 is also inclined by a substantially angle c. With respect to the position of the upper end of the front end surface of the protruding member 70, The position of the lower end of the front end face of the protruding member 70, For the rear side (the outer side of the housing 10). E.g, Angle c, It is a predetermined angle within a range of ~5 degrees. therefore, Has a relationship of angle cS angle b. When the angle b is set to be large, You can also set the angle c to be smaller. Conversely, When the angle b is set to be small, The angle c can also be set larger. E.g, If the angle b is set to 1 degree, The angle c can also be set to zero. that is, As long as the rear end face of the spacer 25 is tilted, Then, the front end surface of the protruding member 70 may not be inclined. You can also set the angle b to 5 degrees. Set the angle c to 5 degrees. Further, the front end surface of the member 70 is opposed to the front side wall surface of the recessed portion 39, but the front side wall surface of the recessed portion 39 of the front end surface of the projection member 70 is formed. With respect to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed, It can also be roughly vertical. in this way, By forming the front end surface of the protruding member 70 and the rear end surface of the spacer 25 into an inverted "eight" shape, For the user, The attachment and detachment of the dust accommodation portion 5 of the cleaner body 1 becomes easy. In particular, the contact area is increased by increasing the formation angle c with respect to the protrusion member 7〇, Further, the attachment and detachment of the dust accommodating portion 5 can be facilitated by increasing the formation angle b' of the spacer 25 having a high viscosity. Furthermore, In the lower portion of the frame 78 of the filter 15, A convex portion 73 having a rear end surface with respect to the filter 15 is provided. Protrusion 73, It protrudes in a direction perpendicular to the rear end surface of the filter 15. on the other hand, At the lower portion of the position facing the frame 78 of the filter 15 in the rear side wall surface of the cleaner body 1, That is, the position facing the convex portion 73 of the filter 15, A concave portion 81 is formed (refer to Fig. 26). The convex portion 73 and the concave portion 81 are provided in a corresponding shape. therefore, Concave 8 1 It is recessed in a direction perpendicular to the rear side wall surface of the cleaner body 1. and, With the convex portion 73 and the concave portion 81, When the dust accommodating portion 5 is attached to the cleaner body 1, The dust-receiving portion 5 is restricted to a mechanism that is displaced in a direction perpendicular to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed. and, When the dust accommodating portion 5 is attached to the cleaner body 1, Before the convex portion 73 of the filter 15 is fitted to the concave portion 81 of the wall surface of the cleaner body 1, It is preferable that the lower end of the front end surface of the projection member 7 abuts against the front side wall surface of the recessed portion 39 to determine the position of the projection member 70 and the length of the front end surface. With this, user, When the dust accommodating portion 5 is mounted on the suction device body 1 -77-201103484, First, the protruding member 70 is abutted against the recess 39, Thereafter, the dust receiving portion 5 is pressed in, Then, the convex portion 73 of the filter 15 is fitted into the concave portion 81 of the wall surface of the cleaner body 1. The dust accommodating portion 5 is attached to the cleaner body 1. therefore, For the user, The dust accommodating portion 5 can be smoothly attached to the cleaner body 1, also, It is also possible to obtain the feeling that the dust containing portion 5 is attached to the cleaner body 1. also, The concave portion 81 having the convex portion 73 of the filter 15 and the wall surface of the cleaner body 1 is provided. When the dust accommodating portion 5 is attached to the cleaner body 1, The dust accommodation portion 5 can be prevented from being displaced in a direction perpendicular to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed. The airtightness of the dust containing portion 5, the dust separating portion 4, and the cleaner body 1 can be maintained. Furthermore, The direction in which the inlet opening of the inlet pipe 3 is formed when viewed from the side as shown in Fig. 22, The angle d is inclined with respect to a vertical line perpendicular to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed. The drawing direction with respect to the dust separating portion 4 is also inclined by a substantially angle d. Relative to the position of the upper end of the inlet opening of the inlet pipe 3, The position of the lower end of the inlet opening of the inlet pipe 3, It is the rear side (the dust separation part 4 side). E.g, Angle d, It is a predetermined angle in the range of 5 degrees to 10 degrees. By inclining the entrance opening of the front end of the inlet pipe 3 integrally formed with the dust separating portion 4 by an angle d, The attachment and detachment of the dust separating unit 4 from the cleaner body 1 becomes easy. Figure 23, A cross-sectional view of the dust collecting device 2 of the third embodiment of the present invention is seen from the right side. In particular, the state in which the dust separating unit 4 is in contact with the dust containing unit 5 is displayed. The axis of the dust collecting device 2, It is the axial center of the inlet pipe 3 and is the axial center of the outer cylinder 6, and is the axial center of the inner cylinder 7, and is the axial center of the front cover 11. -78- 8 201103484 relative to the axis, forming direction (axis direction), One end surface of the dust separating portion 4 in the axial direction and the other end surface in the axial direction, One end surface of the front cover 11 in the axial direction and the other end surface of the axial direction, One end face of the dust receiving portion 5, It is formed substantially vertically. The axis of the dust collecting device 2, a vertical line perpendicular to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed, It is inclined at a angle a. E.g, Angle a, It is a predetermined angle in the range of 40 degrees to 45 degrees. But’ angle a, Can also be set smaller than 40 degrees. therefore, One end surface of the dust separating portion 4 in the axial direction and the other end surface in the axial direction, One end surface of the front cover 11 in the axial direction and the other end surface of the axial direction, One end face of the dust receiving portion 5, The angle 3 is inclined with respect to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed.

On the other hand, at a position corresponding to the protruding member 72 of the front side wall surface of the cleaner body 1, an engaging hole 82 for receiving the protruding member 72 is formed. The engaging mechanism (engaging member 71) or the mechanism for restricting separation is realized by the projecting member 72 and the engaging hole 82. When the dust separating unit 4 is attached to the cleaner body 1, the user first inserts the protruding member 72 into the engaging hole 82, and then the inlet opening end of the inlet pipe 3 abuts against the gasket attached to the cleaner body 1. 22. Thereafter, the lower portion of the other end of the dust separating portion 4 in the axial direction may be pressed against the engaging member 71. When the electric blower 28 is operated to generate an attractive force, the dust separating unit 4 is intended to float from the cleaner body 1, but the convex portion of the tip end portion of the protruding member 72 abuts against the inner wall surface of the engaging hole 82 and is caught. One end in the axial direction of the dust separating portion 4 can be suppressed from being displaced or separated from the front side wall surface of the cleaner body 1. Therefore, the one end in the axial direction of the inlet pipe 3 is also prevented from being displaced or separated from the gasket 22, and the decrease in the attraction force or the generation of noise is suppressed. Instead of the projection member 72 being formed in the dust separating portion 4, the engagement hole 82 is formed in the front side wall surface of the cleaner body 1, and the projection member 72 may be formed on the front wall surface of the cleaner body 1, and the engagement hole 82 may be formed in the dust separation portion 4. The position at which the projecting member 72 is formed may be the one end surface of the dust separating portion 4 in the axial direction -83 to 201103484, or the side closer to the upper end, or may be lower than the lower side of the inlet pipe 3. Further, instead of the protruding member 72, a pressing member for pressing the upper end surface of the dust separating portion 4 in the axial direction may be formed on the front side of the cleaner body 1, or may be pressed against the inlet pipe 3. The pressing member of the end face is formed on the front side of the cleaner body i. [Embodiment 4] The details of the dust accommodating portion 5 of the first embodiment will be described as a fourth embodiment. An electric vacuum cleaner according to a fourth embodiment of the present invention is characterized in that a ventilation member (for example, a dust collecting case 12) can be rotated from a first state in which the ventilation member covers the outer casing toward the front side of the outer casing to the ventilation member. The angle at which the opening surface forms a horizontal direction (for example, the angle e - the angle f) is the second state of the predetermined angle within 45 degrees. Still further, in the present invention, the ventilation member (for example, the dust collecting case 12) can be rotated from the first state enclosed in the ventilation member or the outer casing toward the front direction of the outer casing to the opening surface of the ventilation member and the direction in which the handle is formed. The formation angle (for example, the angle e-angle f and the angle h) is the second state of the predetermined angle within 45 degrees. According to the present invention, the ventilation member can be rotated toward the front direction of the casing until the formation angle of the opening surface of the ventilation member and the horizontal direction becomes the second state at a predetermined angle within 45 degrees, or by ventilation. The member is rotated in the front direction of the casing until the angle between the opening surface of the ventilation member and the direction in which the handle is formed is a predetermined angle of 45 degrees or less. The user can easily discharge the dust accumulated in the ventilation member. Further, the electric vacuum cleaner according to the fourth embodiment of the present invention is characterized in that the dust collecting portion is viewed from the side of the mounting member for attaching the ventilation member (for example, the dust collecting box 12) to the outer casing. (for example, the dust accommodating portion 5) is fixed to the outer casing obliquely with respect to the direction in which the rear end surface of the dust collecting portion is formed or perpendicular to the vertical line perpendicular to the bottom surface of the cleaner body. According to the present invention, when the dust collecting portion is viewed from the side by the mounting member for attaching the ventilation member to the outer casing, the direction of formation with respect to the rear end surface of the dust collecting portion or relative to the body of the suction device is The vertical line of the bottom surface is formed obliquely, and the strength of the mechanism for attaching the dust collecting portion to the outer casing can be improved without restraining the front and rear direction of the dust collecting portion, and the bending of the outer casing can be suppressed. Fig. 29 is a front elevational view of the dust containing portion of the fourth embodiment of the present invention as seen from the distal end side in the axial direction. In particular, the state other than the front cover 11 is displayed. The same as Fig. 6, the Fig. 29 shows the state of accumulation of the airflow 62 in the dust collecting case 12 and the dust 83 in the dust collecting box 12 with respect to Fig. 6. As shown in Fig. 26, the inlet opening of the intake duct 27 is formed in the left-right direction of the cleaner body 1 so as to be close to the left side. Further, as shown in Fig. 5(B), the outlet opening of the outer flow path 35 is formed to be higher than the center line of the front cover 1 1 in the vertical direction, and has a shape symmetrical in the left-right direction. Further, as shown in Fig. 10, the airflow 62 that has been swirled on the outer peripheral side of the inner cylinder 7 flows into the outer flow passage 35 in the circumferential direction (the swirling direction), and is turned toward the axial direction by the downstream side wall surface 65. However, even if the downstream side wall surface 65 is turned toward the axial direction, the component in the circumferential direction (rotational direction) remains in the airflow 62, so that the airflow 62' is the other end portion in the axial direction of the dust separating portion 4 of the outer flow passage 35. (the intermediate portion of the outer flow path 35), the one end portion of the front cover 1 1 -85 - 201103484 in the axial direction (the intermediate portion of the outer flow path 35) also faces the axial direction and faces the circumferential direction, on the axis of the front cover 11 The other end portion of the direction (the exit portion of the outer flow path 35) also faces the axial direction and faces the circumferential direction. That is, as shown in Fig. 29, the airflow 62 in the inlet opening portion of the dust collecting case 12 is not only the axial direction but also the clockwise circumferential direction of the half turn. Therefore, the airflow 62 in the dust collecting case 12 is not only directly sucked toward the filter 15, but also collides with the left side wall surface of the dust collecting case 12 facing the left direction in the circumferential direction, and collides with the bottom surface of the dust collecting case 12. The airflow 62 colliding with the bottom surface of the dust box 12 collides with the right side wall surface of the dust box 12, and is swirled toward the other end surface of the front cover 11 toward the entrance opening of the dust box 12, and flows into the set. The initial airflow 62 within the dust box 12 merges. Therefore, the air flowing into the dust box 12 will generate a swirling airflow 6 2 on the near side, the left side, the far side, the right side, and the near side in the dust box 12 (the dust is seen from above) In the case of the accommodating portion 5, it is a clockwise rotation." Especially when the mesh member 12 is formed with the mesh member, the collision or swirling of the airflow 62 is more remarkable. However, since the bottom surface of the dust box 12 and the side wall surfaces of the upper and lower sides are ventilated, the air flow from the bottom surface of the dust box 12 and the side wall surfaces of the upper and lower sides to the outside of the dust box 12 also occurs. At this time, the upper right portion of the dust box 12 formed by the bottom surface of the dust box 12 and the upper side wall surface and the right side wall surface has a strong swirling force of the air current 62, so that the dust contained in the air is swirled by the swirling flow. The centrifugal separation action caused by the centrifugal separation is carried out toward the outer peripheral side of the swirling flow, and is accumulated in the upper right portion of the dust collecting case 12. That is, the dust is gradually accumulated from the upper right portion of the dust box 12. Therefore, regardless of whether the inlet opening of the intake duct 27 exists on the left side and the dust 83 accumulates from the right side, even if the dust 86' is stored in the dust box 12, it is difficult to hinder the generation of the swirling flow, and correspondingly Since the portion of the inlet opening of the intake duct 2 is less likely to be clogged by the dust 83, the accumulation of the dust 83 is suppressed by the energy loss of the air, and the decrease in the attractive force due to the accumulation of the dust 8 3 can be suppressed. Further, when the dust 8 3 is accumulated from the upper right portion of the dust collecting case 12, the air flow from the bottom surface of the dust collecting case 12 and the side wall surfaces of the upper and lower sides to the dust collecting case 12 is also caused, so that the dust box 12 is The bottom surface, the upper and lower side wall surfaces, and the dust will adhere to it. Fig. 30 is a cross-sectional view showing the dust receiving portion of the fourth embodiment of the present invention as seen from the side. In particular, it is shown that the front cover 11 is closed with respect to the outer casing 10. The outer flow path 35 is suddenly enlarged in a position beyond the one end surface of the front cover 11 in the axial direction. Further, the position inside the dust collecting box 12 which exceeds the other end surface of the front cover 前 in the axial direction of the outer flow path 35 (the outlet opening of the outer flow path 35) is also suddenly enlarged. Therefore, the airflow 62 is suddenly slowed and spread at a position beyond the one end surface of the front cover 11 in the axial direction, and further, beyond the other end face (outlet opening) of the front cover 11 in the axial direction. The position inside the dust box 12 also suddenly becomes slow and spreads. Further, the upper end and the lower end of the bottom portion 84 of the dust box are asymmetrical. Specifically, the upper end of the bottom portion 84 of the dust box, that is, the joint portion of the bottom surface of the dust box 13 and the upper side wall surface, is lower than the bottom end of the bottom portion 84 of the dust box 13 and the bottom surface of the dust box 13 The joint portion is formed gently to set the radius of curvature to be large. Since the axial direction of the dust box 12 is inclined at an angle a with respect to the axial direction of the filter 15, the lower end of the bottom portion 84 of the dust box is the closest filter I5 in the dust box 13. The center point of the upper and lower sides of the opening of the side flow path 35 in the axial direction of the front cover 11 and the center point of the upper end of the axial direction (inlet surface) of the filter 15-87-201103484 are connected. The straight line (line division) is located at the lower end of the bottom portion 8 of the dust box. The airflow 62 flowing into the dust collecting box 12 is directed toward the filter 15, and is diffused at a position from the outlet opening of the outer flow path 35, and a part is directed toward the dust collecting along the upper side wall surface of the dust box 12. The bottom portion 84 of the cartridge, the other portion of which is impacted against the bottom 84 of the dust box and swirls along the lower side wall surface of the dust box 12 toward the inlet opening of the dust box 12. Since the upper side wall surface of the dust box 12 is formed in the direction toward the air flow 62 along the filter 15, it is easy to flow toward the bottom portion 84 of the dust box, and on the other hand, due to the lower side wall surface of the dust box 12, The direction of the gas stream 62 toward the filter 15 is formed toward each other, so that the air flow is liable to stay. The upper side wall surface of the dust collecting case 12 is located on the upstream side of the lower side wall surface of the dust collecting case 12, and because of the strong swirling force, the dust 83 is accumulated from the upper end of the bottom portion 84 of the dust collecting case 12. Further, on the outer side of the upper end of the bottom portion 84 of the dust collecting case, there is provided a projecting member 8 7 which restricts the front side of the dust collecting case 12 facing the outer casing 10. It is preferable that the projecting member 87 is formed to extend in a radial direction of a circle centering on the axis 14 which is the pivot point of the dust box 12. Alternatively, the protruding member 87 is preferably provided with a surface along the radial direction. An enlarged view of Fig. 30 is a view showing a support structure for the outer casing 10 of the dust collecting case 12. Fig. 31 is a rear elevational view of the dust containing portion 5 of the fourth embodiment of the present invention as seen from the rear side. In particular, the state in which the filter 15 is opened with respect to the outer casing 1 is displayed. As shown in the enlarged view of Fig. 30, the dust collecting case 12 is attached to the inner side of the casing 1 by the mounting member 85. Thereby, the appearance damage of the outer casing 10 can be suppressed. As shown in Fig. 31, the attachment member 85 has a substantially quadrangular shape and is provided with a certain width in the front-rear direction and the left-right direction. Yu An 8 - 88 - 201103484 Both ends of the mounting member 85 in the left-right direction are formed with protrusions 86. The mounting member 85 is fixed to the outer casing 10 by embedding the protruding portion 86 into a portion of the outer casing 10 (a portion formed from the lower surface of the outer casing 1〇 extending in the outer casing 1 to the oblique direction). Then, the shaft 14 is supported on the front side of the mounting member 85. The shaft 14 may be provided with a coil spring that exerts an elastic force in a direction in which the dust box 12 is pushed toward the front cover 1 1 side. On the other hand, when the dust box 12 is ejected toward the front side, the mounting member 85 is left on the side of the casing 10, and only the dust box 12 is displaced toward the front side with the shaft 14 as a fulcrum. Here, the mounting member 85 is perpendicular to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed, and the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed. Or, the direction in which the other end surface of the dust accommodation portion 5 or the outer casing 10 in the axial direction is formed is formed in an oblique direction. The mounting member 85 may be formed in a direction substantially perpendicular to the direction in which the dust receiving portion 5 or the one end surface of the outer casing 10 is formed in the axial direction. The dust accommodating portion 5 and the outer casing 19 have a substantially inverted triangle shape or a substantially fan shape when viewed from the side, that is, the lower side is shorter than the upper side. When the mounting member is formed in the horizontal direction as in Patent Document 3, the lower side of the dust containing portion 5 becomes longer, and the length of the dust collecting device 2 in the axial direction also becomes longer, and the front and rear of the cleaner body 1 are formed. The length of the direction also becomes longer. When the mounting member 85 itself is shortened, the strength for fixing the mounting member 85 to the outer casing 10 is insufficient. In particular, when the coil spring is formed on the shaft 14, the reaction force is generated by the elastic force of the coil spring of the attachment member 85, so that the attachment member 85 is easily bent and damaged. Further, in the state in which the dust collecting case 12 is ejected, the load on the dust collecting case 12 is also applied to the mounting member 85, so that it is easy to be bent and damaged. Here, in order to make the -89-201103484 mounting member 85 long (1/2 or more of the axial direction of the dust collecting case 12), the lower side of the dust containing portion 5 is made short, and the mounting member 85 is oriented. Oriented in a direction parallel to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed, and in a direction perpendicular to the bottom surface of the cleaner body 1 or the surface on which the suction device body 1 is placed, or in relation to dust. The direction in which the portion 5 or the other end surface of the outer casing 10 is formed in the axial direction is formed in an oblique direction. In Fig. 31, the user, by pressing the portion of the mounting member 85 which is "pressed", removes the dust box 12 from the outer casing 10 together with the mounting member 85. Fig. 3 is a cross-sectional view showing the dust receiving portion of the fourth embodiment of the present invention as seen from the side. In particular, the front cover 11 is opened with respect to the outer casing 10, and the dust box 12 is ejected toward the front of the outer casing 10. As shown in Fig. 23, the axis is inclined at an angle a with respect to the vertical direction, the direction in which the one end surface of the front cover 11 and the other end face in the axial direction are formed, and the direction in which the end face of the outer casing 10 is formed in the axial direction. It is perpendicular to the axis direction. Therefore, the direction in which the one end surface of the front cover 11 in the axial direction and the other end surface in the axial direction and the direction in which the one end surface of the outer casing 10 is formed are inclined at an approximate (180-a) degree with respect to the vertical direction (gravity action direction). It is inclined at a substantially angle a with respect to the horizontal direction (the direction perpendicular to the direction of gravity action). Therefore, the direction in which the one end surface of the outer casing 10 is formed is inclined at an angle e with respect to the horizontal direction, and the angle e is substantially equal to the angle a. Therefore, for example, the angle e is a predetermined angle in the range of 40 to 45 degrees as the angle a. The front cover 11 is pivoted from the front direction toward the lower side with respect to the outer casing 1 with the shaft 3 1 as a fulcrum, but as shown in Fig. 32, the end face of the front cover 11 and the axial direction are 8-90- 201103484 The formation direction of the other end surface is openable at least in a substantially vertical direction. The front cover 11 is openable at least at an angle (e + 90) with respect to the direction in which the one end surface of the outer casing 10 is formed in the axial direction. The direction in which the front cover 1 is formed with respect to the one end surface of the outer casing 10 in the axial direction is preferably larger than the angle (e + 90 ). Further, the angle with respect to the direction in which the surface in the horizontal direction is formed is the same as the angle with respect to the normal direction of the surface in the vertical direction. The dust box 12 is divided into an upper half 88 of the dust box and a lower half 89 of the dust box, with the outer shaft 13 formed in the middle of the bottom portion 84 of the dust box as a fulcrum. The upper half 88 of the dust box and the lower half 88 of the stack are relatively open only at an angle g. For example, the angle g is 1 1 . About 5 degrees. The protruding member 8 7 (a part of the dust collecting box 1 2 ) formed on the outer side of the upper half 8 8 of the dust collecting case is an inner side dust collecting box 1 2 which is open to the end face of the outer casing 1 轴 in the axial direction. The popup is restricted. With this limitation, the front end surface of the lower half 89 of the dust box is at the opening angle f with respect to the one end surface of the outer casing 1 in the axial direction. For example, the angle f is about 3 3 degrees. Further, the front end surface (opening surface) of the dust collecting case 12 is substantially parallel to the bottom surface. The front end surface of the upper half portion 8 8 of the dust box is at an opening angle (f_g) with respect to the one end surface of the outer casing 10 in the axial direction. Further, the front end surface of the lower half 89 of the dust collecting case is opened to an angle (e - f) with respect to the horizontal direction. For example, when the angle e is set to 40 degrees and the angle f is set to 33 degrees, the angle (e - f) is about 7 degrees. That is, the front end surface of the lower half 89 of the dust box is approximately 7 degrees with respect to the horizontal direction, and the front end surface of the upper half 88 of the dust box is close to the horizontal direction (1 1 . 5 + 7 )= 1 8. About 5 degrees. Therefore, the front end face of the upper half 88 of the dust box and the front end face of the lower half 89 of the dust box -91 - 201103484 will become close to the horizontal direction, that is, in the middle of the horizontal direction and the vertical direction. 45 degrees is closer to the horizontal direction, in other words, the normal direction of the front end surface of the upper half 88 of the dust box and the front end surface of the lower half 89 of the dust box is near the vertical direction (gravity action direction), that is, The dust 83 accumulated in the dust collecting case 12 is liable to fall down more than 45 degrees in the middle of the horizontal direction and the vertical direction. The handle 16 is gently slanted from the rear end of the dust receiving portion 5 and at the front side. The user holds the front side of the handle 16 in order to open the front cover 1 1 and operate the button 17 formed in front of the handle 16. Depending on the position of the center of gravity of the dust accommodating portion 5, when the user grips the front side of the handle 16, the front side of the handle 16 is inclined, so that the entire dust accommodating portion 5 is slightly inclined upward with respect to the horizontal direction. . When the forming direction (wiring direction) of the front side of the handle 16 is inclined by an angle h with respect to the horizontal direction, the entire dust containing portion 5 is inclined upward by an angle h with respect to the horizontal direction. For example, the angle h is about 12 degrees. When the user grips the front side of the handle 16 to discharge the dust 8 3 in the dust box 12, the front end surface of the lower half of the dust box 89 is angled with respect to the horizontal direction (e-f+h). For example, close to 19 degrees, the front end face of the upper half 88 of the dust box is an angle (e - f + g + h ) with respect to the horizontal direction, for example, close to 30. About 5 degrees. Therefore, even if the user holds the front side of the handle 16 to discharge the dust 8 3 in the dust box 12, the front end face of the upper half 8 8 of the dust box and the lower half 89 of the dust box The front end surface is close to the horizontal direction, that is, since it is closer to the horizontal direction than 45 degrees between the horizontal direction and the vertical direction, the dust 83 accumulated in the dust box 12 can be easily dropped. However, 8 - 92 - 201103484, the handle 16 is inclined from the rear end of the dust receiving portion 5 and gently inclined on the front side. It is also possible to make the handle 16 straight in the horizontal direction. Fig. 3 is a side view showing the dust accommodating portion of the fourth embodiment of the present invention. On the upper left side of the front cover 11, a transparent or translucent window 74 is formed in which the amount of accumulated dust is visually observed. In particular, when the outer casing 10 is opaque, the window 74 must be provided because the user cannot visualize the accumulation amount of the dust 83. A trash disc line 90' is drawn at window 74' to allow the user to know when the trash was discarded. The direction in which the garbage discarding line 90 is formed is a direction that is substantially perpendicular to the direction in which the dust 83 in the dust collecting box 12 is accumulated, that is, a direction that is substantially perpendicular to the suction direction toward the filter 15, that is, relative to The substantially horizontal direction is a substantially vertical direction. Further, the position where the garbage disposal line 90 is formed is such that the dust 83 accumulated in the dust collecting case 12 does not scatter from the opening of the one end portion of the front cover 1 in the axial direction, for example, the axial direction of the front cover 1 1 The position corresponding to the lower end of the opening of one end. Even when the outer flow path 35 is closed by the dust, since the inner flow path 36 is opened, the suction force is not excessively lowered. Therefore, by setting the position at which the garbage disposal line 90 is formed so that the dust 8 3 does not scatter from the opening of the front cover 1 1 , dust can be accumulated in the dust collecting box 1 2 as much as possible, and the user can be reduced. The number of times the dust is discharged can reduce the burden on the user. However, in the case of giving priority to the maintenance of the attractive force, the formation position of the garbage disposal line 90 may be set to the rear side and the lower side. The window 74 may be formed on the right side instead of being formed on the left side of the front cover 11 or may be formed in the outer casing 1 instead of being formed on the front cover 11. Figure 34 is a cross-sectional view taken from the right side -93 - 201103484 of the dust containing portion of the fourth embodiment of the present invention. Fig. 34(a) is a view showing the fully open state of the dust box 12, and Fig. 34(a) shows the half open state of the dust box 12. As described above, the protruding member 87' abuts against the axial direction of the outer casing 1 - the inner side of the end opening, and is used to restrict the ejection of the dust collecting box 12 to become fully opened as shown in Fig. 34 (a). status. As shown in the enlarged view of Fig. 34(a), on the front side of the upper side of the upper portion 88 of the dust collecting case, there are provided a projecting member 91 and a projecting member 92 for maintaining the dust box 12 in a half-open state. Both the protruding member 91 and the protruding member 92 have a triangular shape. The protruding member 91 and the protruding member 92 are formed linearly in the front-rear direction, the protruding member 91 is formed on the front side, and the protruding member 92 is formed on the rear side, and a gap (concave portion) is provided between the protruding member 91 and the protruding member 92. The height of the apex of the projecting member 91 and the projecting member 92 is preferably the same as the upper surface of the upper portion 88 of the dust collecting case, or the lower side of the projecting member 92. In Fig. 34(a), the inclination angle of the left side (front side) of the projecting member 91 is preferably larger than the inclination angle of the right side (rear side face) of the projecting member 92. The inclination angle of the left side (front side) of the protrusion member 92 is larger than the inclination angle of the right side of the protrusion member 92. The inclination angle of the left side of the projecting member 92 is preferably close to 90 degrees (80 degrees to 90 degrees) with respect to the bottom side. The inclination angle of the right side (rear side surface) of the projection member 91 is larger than the inclination angle of the left side of the projection member 91. Further, when the dust box 12 is ejected toward the front of the casing 10, since it has a velocity momentum by the weight of the dust box I2 or the spring force of the spring, it will be oriented toward the axis of the casing 1 The inner protruding end portion 93 of the end face opening slides over the left side of the projecting member 91, and then flies over the gap between the projecting member 8-94-201103484 member 91 and the projecting member 92, and slides to the right of the projecting member 92. Therefore, the dust box 12 does not become the half-open state shown in Fig. 34(b), but is in the fully open state. On the other hand, in the case where the dust box 12 is housed in the casing 1 by the user's operation, when the pressing force of the user is strong, the end portion 93 leaps over the protruding member 91 and the protruding member. The gap between 92, but when the user's pressing force is weak, 'end portion 93, slips over the right side of the protruding member 92, and passes over the apex of the protruding member 92, then slides over the left side of the protruding member 92, and falls on the protruding member A gap between the protrusion 91 and the protrusion member 92. At this time, when the user removes the pressing force against the dust box 12, the end portion 93 abuts against the left side of the protruding member 92 to restrict the dust box I2 from being ejected (rotated) toward the front of the outer casing 10, and Become a half open state. And 'from the half-open state, the user applies a pressing force to one end surface of the front cover 11 in the axial direction, so that the front cover 11 abuts against the front surface of the dust box 12, and the end portion 93 slides over the protruding member 91. On the right side, the apex of the protrusion member 91 is passed over, and then the left side of the protrusion member 91 is slid, the dust box 12 is placed in a stored state, and the front cover 1 1 is fully closed. However, since the left side of the protruding member 91 is also inclined, even if the front cover 11 is in an open state, or even if the user does not press the dust box 12, the front opening of the dust box 12 is directed upward. The end portion 93 abuts against the left side of the protruding member 91, and the storage state of the dust box 12 can be maintained. Thereby, the user can easily store the dust box 1 2 in the casing 10, and the front cover 1 1 can be easily closed. Further, in the half-open state, the user sets the front opening of the dust box 1 2 upward, sets the fiber paper on the inner side of the dust box 12, and presses the bottom surface of the dust box 12 from the fiber paper, and then The dust box 12 is press-fitted into the casing 1〇-95-201103484, and the dust box 12 can be housed in the casing 1 while the front cover 11 is opened. The user can then close the front cover 1 1. Therefore, the user can perform the operation of accommodating the dust box 12 in the casing 10, and press the fiber paper into the bottom surface of the dust box 12, so that the fiber paper can be closely attached to the dust collection. The bottom surface of the case 12 and the side walls of the upper, lower, left, and right sides are securely attached. Further, as long as the fiber paper can be attached to the bottom surface of the dust box 12 and the side walls of the upper and lower sides, the dust can be prevented from being damaged when the dust is collected. [Embodiment 5] Hereinafter, other embodiments of Embodiments 1 to 4 will be described. In the fourth to fourth embodiments, the end portion of the outer peripheral portion of the spacer 9 in the axial direction is terminated in the axial direction, and in the fifth embodiment, the axial end of the outer peripheral portion of the spacer 9 is formed. The side end portion is characterized in that it extends toward the outer circumferential direction. Further, with respect to the first to fourth embodiments, in the fifth embodiment, the rib 95 is added to the step difference. In addition, in the fifth embodiment, the ribs 96 for positioning are added to the distal end portion of the inner cylinder 7 in the axial direction. With respect to the first to fourth embodiments, in the fifth embodiment, the convex portion 98 for positioning is added to the lower side of the outer circumferential surface of the spacer 9 of the inner cylinder 7. With respect to the first to fourth embodiments, in the fifth embodiment, the ribs 104 extending in the axial direction are formed in the outer flow path 35 in the front cover, and the outer flow path 35 is narrowed on the upper side. Its characteristics. With respect to the first to fourth embodiments, in the fifth embodiment, a through hole that communicates with the outside is added between the shim receiving surface 76 of the front cover 11 and the shim receiving surface 77. This point is -96-201103484 It is characterized by it. In other words, the first dust collecting portion (for example, the dust separating portion 4) is an inner cylinder 7 having a plurality of through holes in a circumferential surface, and is wrapped in a substantially cylindrical outer cylinder. In the sixth portion, a sealing member (for example, a gasket 9) is provided between the end portion on the second dust collecting portion side of the inner cylinder (for example, the axial bottom end portion) and the outer cylinder 6, and the second set of the sealing member The end portion 'on the dust side is extended toward the outer peripheral side (the extension portion 94). Thereby, it is possible to sufficiently ensure the airtightness of the end portion of the inner cylinder on the second dust collecting portion side and the outer cylinder, and it is possible to reduce the energy loss of the air or to reduce the noise. Further, the present invention is characterized in that the first dust collecting portion (for example, the dust separating portion 4) is formed by enclosing an inner cylinder 7' having a plurality of through holes in a circumferential surface thereof in a substantially cylindrical shape. The inside of the cylinder 6 has a flow path (for example, the recessed portion 8 and the guide tube) formed from the end portion of the inner cylinder 7 on the suction port side (for example, the axial end end side end portion) toward the outer circumferential surface of the inner cylinder 7 3 8 ), a portion of the inner surface of the end portion on the suction port side of the outer tube 6 facing the side wall of the flow path has a protruding member (for example, a rib 95 ). Thereby, the airtightness of the end portion of the inner cylinder of the inner cylinder and the outer cylinder can be sufficiently ensured and the energy loss of the air can be reduced or the noise can be reduced. Further, the present invention is characterized in that the first dust collecting portion (for example, the dust separating portion 4) is formed by enclosing an inner cylinder 7' having a plurality of through holes in a circumferential surface in a substantially cylindrical shape. A projection member (for example, 'ribs 96) is provided on the lower side of the end portion of the inner tube 7 on the suction port side (for example, the end portion on the tip end side in the axial direction). Therefore, when the inner cylinder is housed in the outer cylinder, it is easy to position the outer cylinder and the inner cylinder, and the inner cylinder can be easily accommodated in the outer cylinder. According to the present invention, the first dust collecting portion (for example, the dust separating portion 4) ' is an inner cylinder 7' having a plurality of through holes in the circumferential surface, and is enclosed in the outer cylindrical tube 6 having a substantially cylindrical shape. The end portion of the inner cylinder 7 on the second dust collecting portion side (for example, the 'axial end side end portion) and the outer cylinder 6 have a sealing member (for example, the gasket 9)' among the outer peripheral surfaces of the sealing member. The lower side 'is provided with a protruding member (for example, the convex portion 98). Thereby, when the inner cylinder is housed in the outer cylinder, the relative positioning of the outer cylinder and the inner cylinder can be easily performed, and the inner cylinder can be easily attached to the outer cylinder. Further, the present invention is characterized in that the second dust collecting portion (for example, the dust containing portion 5) is a flow path that communicates with the first dust collecting portion (for example, the dust separating portion 4) (for example, the 'outer flow path' The lower side wall surface of the 3 5 ) is formed by a protruding member (for example, the rib 1 〇 4 ) that extends in the axial direction. By this, it is possible to prevent the dust accumulated in the second dust collecting portion from flowing backward or scattering toward the first dust collecting portion side. Further, the 'invention' is characterized in that a portion in which the first dust collecting portion (for example, the dust separating portion 4) communicates with the second dust collecting portion (for example, the dust containing portion 5) (for example, the front cover 1 1) 'There is a hole that communicates with the flow path (for example, the outer flow path 35) that connects the first dust collecting portion and the second dust collecting portion with the outside of the dust collecting device 2 (for example, 'atmosphere') (for example, a through hole) 1 〇 5 ). Thereby, it is possible to suppress the passage of the dust to block the communication between the first dust collecting portion and the second dust collecting portion. Fig. 35 is a cross-sectional view showing the inner cylinder of the fifth embodiment of the present invention as seen from the right side. The enlarged view of Fig. 35 is an enlarged view showing the bottom end portion of the lip portion 68 and the spacer 9 in the axial direction 8 - 98 - 201103484. The outer peripheral portion of the spacer 9 is located on the outer peripheral side of the lip portion 68. The end surface on the outer peripheral side in the axial direction of the outer peripheral side of the spacer 9 is located at the distal end side in the axial direction from the end surface on the bottom side in the axial direction of the lip portion 68. The outer peripheral surface of the spacer 9 is oriented in the axial direction, but its outer diameter is gradually enlarged at the bottom in the axial direction and inclined with respect to the axial direction. When the inner cylinder 7 is inserted into the outer cylinder 6, the outer circumferential surface of the gasket 9 abuts against the inner circumferential surface of the outer cylinder 6. At this time, the outer diameter of the spacer 9 is enlarged in the axial direction bottom portion of the outer peripheral portion, and is pressed (pressed) toward the inner surface of the outer cylinder 6 in the radial direction, and is elastically deformed so that the outer peripheral portion of the spacer 9 is axially bottomed. It is in close contact with the inner surface of the outer cylinder 6 to ensure airtightness of the inner cylinder 7 and the outer cylinder 6. However, only the close contact in the radial direction does not sufficiently ensure the airtightness, and there is still an air leak, which causes energy loss of the air or noise. Here, in the fifth embodiment, as shown in the enlarged portion of Fig. 5, the outer portion of the outer peripheral portion of the spacer 9 is extended toward the outer peripheral side to form the extension portion 94. Thereby, the axially bottom portion of the outer peripheral portion of the spacer 9 has a substantially L-shaped shape when viewed in a cross section. The extension portion 94 is preferably formed by one circumference around the spacer 9. Further, the width of the extension portion 94 in the radial direction is preferably the same as the thickness of the outer wall of the outer tube 6, but it may be slightly smaller than the thickness of the outer wall of the outer tube 6, or may be slightly larger. When the inner cylinder 7 is inserted into the outer cylinder 6, the outer circumferential surface of the gasket 9 abuts against the inner circumferential surface of the outer wall of the outer cylinder 6, and the surface of the front end side of the extension portion 94 in the axial direction abuts An end surface of the outer tube 6 on the bottom side in the axial direction. That is, the end surface of the outer tube 6 on the bottom side in the axial direction is covered with the spacer 9. By the extension portion 94, the axis is
C -99- 201103484 向也就是內筒7朝向外筒6內的插入方向，也可確保內筒7 與外筒6的氣密。藉此，可以充分地確保氣密，而能夠減 低空氣的能量損失、亦減低噪音。 第36圖（a)，是從正面觀察本發明之實施例5之塵埃 分離部的立體圖，且第1 7圖（a )，是從右側側面觀察本 發明之實施例5之塵埃分離部的側面圖。如第3 6圖（a )的 斷面放大圖所示，於外筒7之軸方向端面之內側的階段差 部分，形成朝向軸方向延伸的肋條（突起）9 5。肋條9 5， 爲板厚大致均一的板狀，並沿著外筒7之軸方向端面之內 側的階段差部分彎曲。肋條95之軸方向的高度D4，例如， 爲5〜6mm左右。D4> (D3-D2)。亦即，肋條95之軸方 向的高度，是比階段差還大。相對於在外筒7之軸方向端 面的內側形成有階段差的範圍，形成有肋條95的範圍，是 比形成有階段差的範圍還要短。另一方面，於外筒7之軸 方向端面的內側之中，在對應於內筒6之軸方向前端部的 部分，雖然沒有形成階段差，但形成有肋條95。肋條95， 亦沿著內筒6之軸方向前端部彎曲。因此，肋條95，於外 筒7之軸方向端面的內側之中，是從對應於引導管38之軸 方向前端部之部分的一部分，一到對應於內筒6之軸方向 前端部之部分的一部分爲止，連續地形成。不過在此，肋 條9 5，也可以不形成在對應於內筒6之軸方向前端部的部 分上。形成有肋條95的範圍，只要至少形成在比內筒7的 上下中心還更上側即可。如斷面放大圖所示，以使引導管 3 8的軸方向前端部可抵接於階段差之方式來組合內筒6及 -100- ⑧ 201103484 外筒7時，肋條95的內周面’是與引導管38之軸方向卽端 部的外周面及內筒6之軸方向前端部的外周面成爲相向（ 較佳爲成爲抵接）。該肋條95亦由於具有：外筒7之軸方 向端面的內側與引導管38之軸方向前端部及內筒6之軸方 向前端部之間的密封功能’所以相較於只形成階段差之情 形時，可以減低空氣的能量損失、或是減低噪音。又’只 要形成有肋條9 5，沒有形成階段差亦可。 第3 7圖，是從外延部內側來觀察本發明之實施例5的 內筒的立體圖。如第35圖、第36圖（a)、第37圖所示， 在內筒6的軸方向前端部之中的下側，形成朝向軸方向延 伸的肋條（突起）9 6。如第3 6圖（a )所示之方式，肋條 96，若從正面觀察時，具有大致梯形形狀，隨著朝向軸方 向前端側接近，肋條96的寬幅逐漸地變小。肋條96，是沿 著內筒6的軸方向前端部而彎曲。如第3 5圖所示，肋條96 之底部側的厚度，雖是比圓柱部分5 7之軸方向前端部的厚 度D1稍小若干，但相等亦可。如第35圖所示，肋條96之底 部側的厚度，是隨著朝向軸方向前端側接近，而逐漸地變 小。該肋條96，係具有在將內筒7裝著於外筒6內時的引導 功能。 另一方面，如第36圖（b)之所示，在外筒6之軸方向 前端部之內側之中的下側及入口管3之內側的下側，形成 具有與肋條9 6形狀相對應之形狀的卡合孔9 7。卡合孔9 7， 是形成在：在將內筒7裝著於外筒6時’與肋條96相對應的 位置。不過在此，卡合孔97’爲了使肋條96容易插入，以 -101 - 201103484 比肋條96稍大若干爲佳》卡合孔97，爲封閉的孔穴。卡合 孔97的軸方向底部側（開口側），相較於卡合孔97的軸方 向前端側（封閉側），以使開口面積較大爲佳。亦即，卡 合孔97的軸方向底部側，其寬幅及厚度較大爲佳。 當使用者，手持凹陷部3 9的內側或是外側時，內筒7 的上側，相對於使用者而言亦爲上側，內筒7的下側，相 對於使用者而言亦爲下側。使用者，在以手握持凹陷部39 的內側或是外側來將內筒7裝著於外筒6內時，只要將位於 下側的肋條96插入至卡合孔97，由於圓周方向或左右方向 之內筒7與外筒6的相對位置已被定位好，所以之後，就可 以容易將內筒6的上側插入於外筒6內。藉此，也可以抑制 內筒7與外筒6之相對性的位置偏離。並且可以抑制內筒7 相對於外筒6被浮動安裝、或是被彎曲安裝之情形。特別 是，由於肋條96在插入方向之軸方向前端側的寬幅及厚度 較小，卡合孔97之軸方向底部側的寬幅及厚度較大，所以 使用者，即使肋條96與卡合孔97的相對位置有一點偏離時 ’也可以將肋條96插入於卡合孔97。又，也可以將卡合孔 97形成於內筒7的軸方向前端部，而將肋條96形成在外筒6 之軸方向前端部的內側。 如第35圖、第36圖（b)、第37圖所示，在內筒7之墊 片9之外周面之中的下側，於外周側形成突出的凸部98。 凸部98的突出量，爲1mm左右。如第35圖所示，凸部98, 以形成爲延伸於：朝向墊片9之外周面之中的半徑方向擴 大之前方的軸方向部分爲佳。凸部98，是以比墊片9還硬 ⑧ -102- 201103484 的硬質材料所構成爲佳’不過以與墊片9相同的材料一體 形成亦可。 另一方面，如第36圖（b)所示’在外筒6之內周面之 中的下側’形成朝向外周側凹陷的凹部9 9。凹部9 9，是形 成在：當將內筒7裝著於外筒6時，對應於凸部98的位置。 凹部9 9 ’係具備有對應於凸部9 8的形狀。凸部9 8，爲封閉 的孔。 使用者’在以手握持凹陷部3 9的內側或是外側來將內 筒7裝著於外筒6內時，只要將位在比肋條9 6更下側位置的 凸部98嵌入於凹部99，然後，將肋條96插入於卡合孔97， 由於圓周方向或左右方向之內筒7與外筒6的相對位置已被 定位好，所以之後，就可以容易將內筒6的上側插入於外 筒6內。藉此，相較於只有形成肋條96及卡合孔97之情形 ，可以抑制內筒7與外筒6之相對性的位置偏離。並且可以 抑制內筒7相對於外筒6被浮動安裝、或是被彎曲安裝之情 形。又，由於將凸部98形成於內筒7之墊片9的外周面，將 凹部99形成於外筒6之外周壁的內周面，所以對於軸方向 ，也成爲相對性的抵抗。因此，藉由凸部98及凹部99，也 可以抑制：在內筒7已被裝著於外筒6內的狀態下，當使用 者以手持凹陷部39的內側或是外側時，內筒7從外筒6脫落 之情事。又，也可以將凹部99形成於內筒7之墊片9的外周 面，而將凸部98形成於外筒6之外周壁的內周面。 於唇部68及唇部69、和墊片9的表面施以壓花加工、 或是形成微細的凹凸亦可。或是，於唇部68及唇部69、和 -103- 201103484 墊片9的表面，塗佈潤滑劑亦可。作爲潤滑劑者，例如， 可使用含氟的材料。或者是，於唇部68及唇部69、和墊片 9，混練含氟亦可。藉此，可以抑制唇部68及唇部69固定 接著於墊片承受面76及墊片承受面77而難以分離、或是， 可以抑制墊片9固定接著於外筒6之外周壁的內周面而難以 分離。只要是可以抑制唇部68及唇部69固定接著於墊片承 受面7 6及墊片承受面7 7、或是，抑制墊片9固定接著於外 筒6之外周壁的內周面者皆可使用，並不受上述實施例所 限定者。 第3 8圖’是從側面觀察本發明之實施例5的塵埃容納 部的斷面圖。第39圖’是從塵埃容納部內側觀察本發明之 實施例5的前蓋的正面圖。 如第3 8圖所示，於前蓋1 1的外側流路3 5內，形成朝向 軸方向延伸之板形狀的肋條104。肋條1〇4，是從前蓋11內 的前端到後端爲止朝向軸方向延伸。其結果，於肋條1 〇 4 的上側形成有外側流路3 5，而於肋條1 〇 4的下側則沒有形 成流路。外側流路3 5的流路斷面，係朝向上方向變窄。於 肋條1 04的下側只要可以防止塵埃蓄積，也可以將肋條！ 〇4 製成大致L字型形狀，使肋條1 04的下側作成爲沒有連通於 集塵盒12的封閉空間。於第39圖中，由於肋條104，是被 隱蔽在止回閥1 〇3的內側’所以以點線表示。如第3 9圖所 示’肋條1 〇 4之左右方向的寬幅，是可達到外側流路3 5之 左右方向的寬幅。藉由此肋條1 〇4，可以抑制蓄積在集塵 盒1 2內的塵埃從外側流路3 5散落。又，藉由肋條〗〇 4，從 ⑧ -104- 201103484 外側流路35所流入的氣流62，由於是朝向上方向，也就是 集塵盒12的上側壁面，所以可以使氣流62的迴旋力增加， 而提升空氣與塵埃的分離能力。 如第3 9圖所示，於外側流路3 5的出口端，形成有止回 閥1 03，該止回閥1 03只覆蓋住在肋條1 04的上側所形成之 外側流路3 5的出口開口。且止回閥1 03，是以上端作爲支 點而朝向集塵盒12旋動。止回閥103，以由彈性材料，例 如橡膠所構成爲佳。藉由該止回閥1 03，可以防止蓄積在 集塵盒12內的塵埃從外側流路35散落。 第40圖，是從軸方向前側觀察本發明之實施例5的塵 埃容納部5的正面圖。是已關閉前蓋1 1的狀態。第4 1圖， 是從上側觀察本發明之實施例5的集塵裝置2的斷面圖。 如第40圖所示，於前蓋1 1之前壁的左側，形成有將前 蓋11的前壁予以貫通的貫通孔105。貫通孔105，是形成在 前蓋1 1之左側之中的墊片承受面76與墊片承受面77之間。 貫通孔105的直徑爲3.4mm左右。貫通孔105若太大，則吸 塵器本體1的吸入工作效率（吸引力）就會降低，貫通孔 105若太小，則無法從貫通孔105吸取適量的外部空氣。貫 通孔105的流路面積，是由與吸塵器本體1之吸入工作效率 (吸引力）的關係來決定爲佳。如第4 1圖所示，貫通孔 105，是與前蓋11的外部（大氣）連通。亦即，貫通孔105 ，是貫通前蓋1 1的前壁，並開口於：沒有與外側流路3 5連 通之前蓋1 1的內側。沒有與外側流路35連通之前蓋1 1的內 側，是從前蓋1 1的側壁與後壁之間的縫隙，與外部連通。 -105- 201103484 如第4 1圖1所示，在塵埃分離部4與塵埃容納部5相結合（ 裝著）的狀態下’貫通孔105’是開口於：唇部68與唇部 6 9之間的空間。前蓋1 1之前壁的左側，是在外側流路3 5之 內筒7之出口端中之位於氣流62的下游側位置。 而且，如第41圖所示，當電動送風機28動作而產生吸 引力時，唇部68與唇部69之間的空間成爲負壓，外部空氣 的氣流1 〇 6，是從外部通過前蓋1 1的側壁與後壁之間的縫 隙而流入於沒有與外側流路3 5連通之前蓋1 1的內側，然後 通過前蓋11之前壁的貫通孔105，流入於唇部68與唇部69 之間的空間。然後，外部空氣的氣流1 0 6，通過外側流路 35之終端之內周側的部分100，與氣流62合流，而朝向外 側流路3 5流入。亦即，於第1 3圖中，氣流6 2，並不是從外 側流路3 5之內筒7的出口端，通過外側流路3 5之終端之內 周側的部分100，而流入唇部68與唇部69之間的空間，而 是與：從唇部68與唇部69之間的空間然後通過外側流路35 之終端之內周側的部分1 00而流入到外側流路3 5之內筒7之 出口端的外部空氣，成爲合流。因此，藉由該貫通孔105 ’可以抑制氣流62中所含的塵埃受到外側流路3 5之終端之 內周側的部分1 00所牽絆住之情事。又，貫通孔1 05的位置 或是形狀，並不受上述所限定，只要是在外側流路3 5之內 筒7的出口端，可將氣流62之下游側的唇部68與唇部69之 間的空間與外部予以連通者即可。例如，也可以將貫通孔 1 〇 5或是細縫（長孔）、形成在唇部6 8。 ⑧ 201103484 〔實施例6〕 於第1圖及第43圖，是顯示本發明之實施例之吸塵器 本體的橫向斷面圖。電氣吸塵器在使用狀態下，吸塵器本 體1爲橫放，電氣吸塵器在收納狀態下，吸塵器本體1爲立 放較佳。電氣吸塵器在使用狀態下，以本體吸氣口 2 1側爲 前方（上游側），以本體排氣口 3 0側爲後方（下游側）時 ，電動吸塵器在使用狀態下，本體吸氣口 21與本體排氣口 3 0相對於地板爲大致呈水平（吸塵器本體1橫放），電氣 吸塵器在收納狀態下，使本體吸氣口 21爲重力作用方向上 側，使本體排氣口 30爲重力作用方向下側（吸塵器本體1 立放）。第1圖及第43圖，係電氣吸塵器在使用狀態下之 吸塵器本體1的橫向斷面圖。 於第44圖，是顯示將集塵裝置2拆卸下之狀態下，將 吸塵器本體1剖斷時之本發明之實施例的吸塵器本體的平 面斷面圖。 又，在本實施例中，如第43圖所示地將吸塵器本體1 橫放之情形時，是將具有本體吸氣口 2 1側作爲吸塵器本體 1的前方向，將具有本體排氣口 30側作爲吸塵器本體1的後 方向，並以跨及於吸塵器本體1的前方向與後方向則稱之 爲吸塵器本體1的縱向方向。 又，在本實施例中，如第43圖所示地將吸塵器本體1 橫放之情形時，以具有把手1 6側作爲吸塵器本體1的上方 向，以具有輪子55側作爲吸塵器本體1的下方向，並以從 吸塵器本體1的上方向跨及於下方向稱之爲吸塵器本體1的 -107- 201103484 高度方向。 又，在本實施例中，如第44圖所示地將吸塵器本體1 橫放之情形時，以從位在吸塵器本體1兩側之輪子5 5之一 方的輪子55到另一方之輪子55稱之爲吸塵器本體1的寬幅 方向。 首先，說明吸塵器本體1的構造。從吸入的空氣中捕 集塵埃的集塵裝置2，是可自由裝卸地配置於吸塵器本體1 的前側。若以集塵裝置2的長邊方向（軸方向）作爲重力 作用方向，則吸塵器本體1的高度將變高。另一方面，集 塵裝置2內之迴旋流的軸方向（集塵裝置2的軸方向）愈接 近重力作用方向則由離心分離作用所產生的分離效果就愈 大，集塵裝置2內之迴旋流的軸方向相對於重力作用方向 若超過45°時則由離心分離作用所產生的分離效果就會極 端地降低。在此，爲了縮小吸塵器本體1的高度並且爲了 抑制由離心分離作用所產生的分離效果的降低，在本實施 例中，集塵裝置2的軸方向，相對於重力作用方向設成40° 〜45°左右。不過，若爲了增高由離心分離作用所產生的 分離效果，集塵裝置2的軸方向相對於重力作用方向設成 小於40°亦可（例如，)。取代將塵埃分離部（迴旋部） 4配置於下側，將塵埃容納部5配置於上側，也可以將塵埃 分離部4配置於上側，將塵埃容納部5配置於下側。此情形 時，入口管3，以接連在塵埃分離部4之軸方向之前側端部 的圓周面爲佳。 集塵裝置2，係具備有：使吸入的空氣迴旋，利用離 -108- ⑧ 201103484 心分離作用（旋風式）將塵埃分離的塵埃分離部4、以及 連通於塵埃分離部4，容納由塵埃分離部4所分離之塵埃的 塵埃容納部5。麈埃分離部4與塵埃容納部5，係被排列在 集塵裝置2的軸方向上，在各別的軸方向端部接連而連通 。亦即’塵埃分離部4，是被配置在吸塵器本體1的前側， 塵埃容納部5，是被配置在比塵埃分離部4後側之吸塵器本 體1的後側。並使使用者能夠容易地分離塵埃分離部4與塵 埃容納部5之方式，使塵埃分離部4與塵埃容納部5連結。 於吸塵器本體1的前端，具備有管狀的本體吸氣口 21。塵 埃分離部4的軸方向之前側端面的一部分，爲呈開口，該 開口部爲接連於入口管3。在此，也可以不是使塵埃分離 部4的軸方向之前側端面接連於入口管3，而是使塵埃分離 部4之軸方向之前側端部的圓周面接連於入口管3。 塵埃分離部4，爲具備有中空之大致圓筒形狀的外筒6 ，以及與外筒6爲同心軸且被內包於外筒6的中空之大致圓 筒形狀的內筒7。爲了抑制由於迴旋流的軸心因重力引起 朝向重力作用方向的偏離使得由離心分離作用所產生之分 離效果降低，而於塵埃分離部4的軸方向相對於重力作用 方向呈傾斜之情形時’亦可使內筒7的軸心相對於外筒6的 軸心朝向下側偏離。如第3圖（A )所示’外筒6的軸方向 一端面（前側端面）’除了接續於入口管3的開口以外爲 被封閉，外筒6的軸方向另一端面（後側端面）’爲呈開 口。外筒6，係爲了使用者看得到塵埃蓄積或是可察覺出 設置於外筒6外的感應器的塵埃蓄積’以由透明或半透明 -109- 201103484 的塑膠或樹脂構成爲佳。內筒7的軸方向一端面（前側端 面）爲被封閉，內筒7的軸方向另一端面（後側端面）， 爲呈開口。如第3圖（A)所示，於內筒7的軸方向一端面 之封閉部分的中央，形成有朝向內筒7的軸方向內側凹陷 的凹陷部8。入口管3，爲與內筒7的軸方向一端面的封閉 部分，亦即凹陷部8相向。如第3圖（A )所示，凹陷部8之 一部分，爲達至內筒7的外周端爲止。爲了減低空氣的壓 力損失，凹陷部8的開口方向，以朝向下側爲佳。不過， 凹陷部8的開口方向，亦可爲上方向或橫向方向。如第3圖 (A )所示，於凹陷部8之內筒7的外周端部，凹陷部8並非 筆直朝向內筒7的半徑方向，而是稍微朝向圓周方向傾斜 。如第1圖所示，凹陷部8的軸方向的深度，爲內筒7之圓 筒部分的軸方向之長度的大致一半左右。不過，凹陷部8 的軸方向的深度，亦可爲跨及於內筒7之圓筒部分的軸方 向之大致全長。於該場合，會變得凹陷部8的開口跨及於 內筒7之圓筒部分的大致全長地形成於內筒7的圓周面的一 部分。再者，於凹陷部8的外周端部，接續有引導管3 8。 引導管38的斷面爲大致1/4圓形形狀，且沿著內筒7的外周 面形成，內筒7的外周面亦形成流路之內壁面的一部分。 引導管38爲於內筒7的外周面，於圓周方向形成數cm左右 。因此，從入口管3朝向軸方向流入之空氣’爲藉由凹陷 部8而改朝向半徑方向’再者，於凹陷部8之內筒7的外周 端部處稍改朝向圓周方向，再於引導管38處改朝向圓周方 向。又，凹陷部8爲並非凹凸’而是以由曲面形成爲佳。 -110- ⑧ 201103484 藉此，可持續抑制壓力損失同時使空氣充分地迴旋。引導 管3 8，即使沒有也沒關係。於內筒7之軸方向另一端面（ 後側端面）的外周，形成有朝向外筒6延伸的外延部34。 亦即，如第3圖（A )所示’內筒7的軸方向另一端面（後 側端面），成爲內筒7的內側開口之圓環狀。 如第3圖（A)所示，外延部34的圓周方向的一部分， 爲呈開口。藉由該開口，內筒7外的空氣’可流入塵埃容 納部5。內筒7，爲了能抑制菌的繁殖’以由含有抗菌作用 的金屬（例如：銀、銅）或抗菌物質（例如：銀、銅）、 或是由塗佈有上述物質的金屬（例如：不鏽鋼）所構成爲 佳。不過，內筒7，包含圓筒部分亦可由樹脂所構成。而 且，如第3圖（A)所示，藉由內筒7從外筒6的軸方向另一 端面朝向軸方向插入，使會抵接於外延部34的外周端外筒 6的內周，其結果，外筒6的軸方向另一端面被封閉。使外 筒6與內筒7以可以讓使用者容易地分離外筒6與內筒7之方 式來連結。於內筒7的圓周面，具備有複數個貫通孔33。 藉由複數個貫通孔33，使內筒7具備有過濾器功能。藉由 該貫通孔33，較粗大垃圾不會朝向流入內筒7內，空氣可 從內筒7外側朝向內筒7內側流入。亦因吸入力不同而有異 ，不過1日元硬幣以上的重量（約1公克）的垃圾，不能從 外筒6內吸起來，會有殘留於外筒6內之情形。藉由使外筒 6與內筒7以可以讓使用者容易地分離外筒6與內筒7之方式 來連結，使得使用者，可容易地分離外筒6與內筒7，可容 易地排出蓄積於外筒6內之垃圾，又，可容易地除去卡在 -111 - 201103484 內筒7的貫通孔33的頭髮或棉絮。 爲了保持塵埃分離部4與塵埃容納部5的接續部之氣密 性，與內筒7的軸方向另一端面，具備有墊片9。墊片9, 不僅只設置於外延部34，亦朝向內筒7的軸方向突出。因 此，內筒7的內側，並非完全中空，藉由墊片9而存在有一 部分封閉空間。再者，於墊片9之朝向內筒7的內側突出之 部分，形成有朝向內筒7的軸方向內側凹陷之凹陷部3 9。 凹陷部3 9爲具備有把手的功能。藉此，使用者將手指插入 凹陷部39，可手持塵埃分離部4或內筒7。外延部34的上側 的一部分，爲呈開口，並連通於前蓋11的外側流路35。亦 即，其爲外筒6的內側且爲內筒7的圓筒部分之外側，爲連 通於前蓋1 1的外側流路3 5。如第3圖（A )所示，外延部3 4 之上側的一部分的開口之圓周方向的壁面，以於圓周方向 之與引導管38的開口相向之側的壁面較高，於圓周方向之 引導管3 8的開口側的壁面較低爲佳。例如，從前方觀察塵 埃分離部4時，若將引導管3 8的開口方向作爲繞逆時針方 向，則外延部34之上側的一部分的開口之圓周方向的壁面 中之左側的壁面爲較高，右側的壁面爲較低。亦即，由於 外延部34的上側的一部分爲呈開口’故外延部34的圓周方 向，不滿內筒7的外周的一周分’而以螺旋狀錯開。因此 ，內筒7外的迴旋流’會碰撞外延部3 4之上側的一部分之 開口的圓周方向之較高的壁面’可平順地改向朝軸方向， 含於迴旋流的塵埃也變得易於朝向塵埃容納部5流動。另 —方面，內筒7的內側’爲連通於前蓋1 1的內側流路3 6。 ⑧ -112- 201103484 塵埃容納部5，爲具備有其軸方向一端面（前側端面 )及軸方向另一端面（後側端面）呈開口，且橫斷面呈大 致倒三角形狀之中空的外殼1 〇。外殼1 〇的軸方向一端面’ 爲藉由可開閉之前蓋11被封閉。於前蓋〗1的下端部具備有 軸31，軸31爲藉由外殼10的下端部被支撐。前蓋11，係以 軸31爲支點而可朝向外殻10的軸方向前後旋動。於前蓋11 之上端部的外殼10側，有卡爪突出。另一方面，於外殼10 的前側上部，具備有使用者可按下之按鈕17 (亦可爲控制 桿），於按鈕1 7，連結有朝向外殻1 0的前側延伸之傳達棒 (桿）18。傳達棒18的一端，爲連結於按鈕17，傳達棒18 的另一端，係形成爲卡爪。傳達棒1 8的另一端的卡爪，於 可卡合於前蓋11的上端部的卡爪。於外殼10閉合有前蓋11 之狀態，傳達棒18的另一端的卡爪與前蓋11的上端部的卡 爪爲卡合一起，可防止前蓋1 1打開。然後，若使用者壓下 按鈕1 7，則傳達棒1 8會朝向前側滑動（亦可朝向上側轉動 )，而傳達棒18的另一端的卡爪與前蓋11的上端部的卡爪 的卡合會被解除，可藉由重力從外殻10將前蓋11打開。相 對於把手16的形成方向爲水平，外殼10的軸方向一端面（ 相當於前蓋1 1部分）的法線方向，是相對於水平方向呈傾 斜45 °〜50°。亦即，使用者握住把手16將塵埃容納部5提起 時，外殼10的軸方向一端面（相當於前蓋11部分），會朝 向下側方向（重力作用方向）。因此，可藉由重力從外殼 1 〇將前蓋1 1打開。又，於後說明，集塵盒（集塵容器）12 ’爲藉由彈簧（彈性體）以朝向外殻1 0的前側彈出之方式 -113- 201103484 被彈推著，由於集塵盒12按壓前蓋11的後面，所以當使用 者按下按鈕17，也可以藉由集塵盒12的按壓力平順地從外 殻10將前蓋1 1打開。 外殼10的軸方向另一端面，爲藉由可開閉之過濾器15 被封閉。於過濾器15的下端部爲具備有軸32，軸32爲藉由 外殼10的下端部被支撐。過濾器15，係以軸32爲支點而可 朝向外殼1〇的軸方向前後旋動。過濾器15，是於斷面形狀 呈大致四角形的框體內，形成有被折成褶狀的過濾器構件 79。如第4圖（B)所示，過濾器構件79的波折方向以縱向 方向（重力作用方向）爲佳。過濾器1 5，例如爲高密度的 HEPA過濾器（High Efficiency Particulate Air Filter)。 所謂HEP A過濾器，爲相對於額定風量粒徑〇·3 // m的粒子 具有99.9 7%以上的粒子捕集率，且爲具有初期壓力損失 245Pa以下的性能之空氣過濾器。於過濾器15之外殼10的 相反側之面，亦可具備有墊片25。藉由墊片25，可保持塵 埃容納部5的軸方向另一端面與吸塵器本體1 (特別是吸氣 導管27入口）的氣密性。又，軸31及軸32，亦可共用。又 ’軸32，並非於過濾器IS的下端部，亦可設置於過濾器15 的上端部。 於外殼10，係將集塵盒12內包起來。集塵盒12的形狀 ’可爲一個面呈開口之盒形狀 '箱形狀或是容器形狀、亦 可爲畚斗形狀。亦即，集塵盒12，係具備有朝向與開口爲 相反側凹陷的形狀。集塵盒1 2的斷面形狀，亦可爲大致四 角形’亦可爲大致圓形，亦可爲大致三角形。集塵盒12的 ⑧ -114- 201103484 斷面形狀，係以從開口面朝向底面變小爲佳。藉此，因斷 面積爲朝向塵埃被排出之側（開口側）擴開，故使用者可 容易地排出蓄積於集塵盒12內之塵埃。集塵盒12的形狀， 爲藉由框體（支架）而形成。於集塵盒12的開口面以外的 底面、上下左右面，以覆蓋或是貼著有由金屬或尼龍等所 構成的網目構件爲佳。不僅於集塵盒1 2的底面，亦藉由使 上下左右面具有通氣性，即使塵埃蓄積於集塵盒12的底面 亦可確保流路，吸入空氣的壓力損失減低，可抑制吸引力 之降低。該網目構件，爲具有通氣性，且具備有捕集塵埃 之過濾器功能。只要爲具有通氣性，且具備有捕集塵埃之 過濾器功能者，代替網目構件亦可爲用後即棄型的纖維紙 ，亦可將網目構件及纖維紙予以組合。例如，使用者亦可 於網目構件上裝著纖維紙。集塵盒12的開口面，爲與外殻 1 〇的軸方向一端面（前側端面）的開口面一致。亦即，爲 集塵盒12的開口方向，與外殼10的軸方向一端面的開口方 向爲相同。而，如第6圖所示，集塵盒12的開口面之外周 端的上側一半左右，爲抵接於外殻1〇的軸方向一端面的內 周面，集塵盒1 2的開口面之外周端的下側一半左右，並沒 有抵接於外殻10的軸方向一端面的內周面。於集塵盒12, 於其下部具備有軸14。軸14，爲被支撐於外殼1〇內。因此 ，集塵盒12以下部的軸14爲支點而可朝向外殼1〇的軸方向 前後轉動。藉此，從塵埃容納部5將前蓋1 1開時，藉由重 力集塵盒1 2的一部分可從塵埃容納部5彈出。相對於外殼 1 0之軸1 4的形成位置，由於爲與相對於外殼1 0之軸3 1的形 -115- 201103484 成位置相同側（下側），故從塵埃容納部5將前蓋1 1開時 ’不會有因前蓋11造成妨礙之情形，集塵盒12的一部分可 從塵埃容納部5彈出。再者，於軸I4，亦可具備有在將集 塵盒1 2朝向前蓋1 1側推出之方向作用彈性力之螺旋彈簧。 藉此，從塵埃容納部5將前蓋1 1開時，藉由彈簧的彈性力 ’集塵盒1 2的一部分可從塵埃容納部5強勁彈出，使用者 可容易地排出蓄積於集塵盒12內之塵埃。再者，集塵盒12 ’被分割成上下，亦即以由上半部的框體（支架）及下半 部的框體（支架）之所謂2個構造物所構成較爲佳。被分 割成2個之集麈盒12，係藉由形成於集塵盒12的底面之外 側的軸1 3而連結一起。因此，如第4圖（A )所示，集塵盒 1 2，係以底面的中間爲支點，集塵盒1 2的開口面被分割成 上下。特別是集塵盒1 2的一部分從塵埃容納部5彈出之時 ，集塵盒12被分割成上下。藉此，使用者可更容易地排出 蓄積於集塵盒12內之塵埃》特別是緊貼於集塵盒12之內面 的塵埃也可容易地刮落。不過，集塵盒12之分割成上下2 個的構成，並非必須。又，如上述般，由於除了外殻1〇的 前側爲相對於重力作用方向傾斜40°〜45°之外再加上，集 塵盒12從塵埃容納部5傾斜30°彈出，所以可使蓄積於集塵 盒12內之塵埃朝向大致重力方向排出。 於前蓋1 1內，形成有朝軸方向貫通之外側流路3 5及內 側流路3 6。而，外側流路3 5 ’爲形成於前蓋1 1的上側’外 側流路3 5的一端爲連通於相當於塵埃分離部4之特別是外 筒6與內筒7的筒部之間的外延部3 4之開口，外側流路3 5的 -116- ⑧ 201103484 另一端爲連通於外殼10之特別是集塵盒12的開口。於電氣 吸塵器停止時，爲了防止蓄積於集塵盒1 2之塵埃逆流於外 側流路3 5及塵埃分離部4，外側流路3 5的另一端以連通於 比集塵盒1 2的開口中的一半更上側或上端附近爲佳。不過 ，外側流路35的另一端，亦可連通於集塵盒12的開口的中 央部。再者，於電氣吸塵器停止時，爲了防止蓄積於集塵 盒1 2之塵埃逆流於外側流路3 5及塵埃分離部4，於外側流 路3 5的內部或是另一端部，以形成覆蓋外側流路3 5之止回 閥（圖示省略）爲佳。止回閥，係以上端爲支點而朝向集 塵盒1 2旋動。不過，止回閥並非爲必須之構成。外側流路 35的斷面積，爲從外側流路35的一端朝向另一端擴大。外 側流路3 5的形成方向，爲從外側流路3 5的一端朝向另一端 且從前蓋1 1的外側朝向中心側方向。亦即，爲從集塵盒1 2 的外側朝向中心側方向。爲了抑制從外側流路35朝向集塵 盒1 2流入之空氣的紊亂，外側流路3 5的形成方向，以集麈 盒12的外側流路35連通之側的壁面（上側壁面）的方向爲 佳。內側流路3 6，爲形成於：從前蓋1 1的中央到下側處， 內側流路36的一端爲連通於塵埃分離部4之特別是內筒7的 軸方向另一端開口 （內筒7內），內側流路3 6的另一端爲 連通於外殼之特別是集塵盒12的外側。內側流路36的另 一端，以連通於集塵盒1 2的外部下側爲佳。內側流路3 6， 爲避開外側流路3 5地形成。內側流路3 6的斷面積，與外側 流路35爲相反地，從內側流路36的一端朝向另一端縮小。 於塵埃容納部5的上部外側，具備有朝向水平方向延 -117- 201103484 伸之使用者可持住的把手1 6。使用者，手持該把手1 6，將 塵埃容納部5朝向上方提起，而仍將塵埃分離部4留於吸塵 器本體1，可僅將塵埃容納部5從吸塵器本體1卸取下來。 又，若將麈埃分離部4及塵埃容納部5予以連結，則使用者 ，只要手持該把手16，將塵埃容納部5朝向上方提起，亦 可將作爲一體之塵埃分離部4及塵埃容納部5，亦即將該集 塵裝置2從吸塵器本體1卸取下來。如第1圖所示，塵埃容 納部5的軸方向另一端面（相當於過濾器15部分）的形成 方向，以比垂直面（重力作用方向）更朝向外殼1 0側傾斜 爲佳。亦即，比起塵埃容納部5的軸方向另一端面的上部 ，以下部更接近於外殼1 0側爲佳。又，如第1圖所示，塵 埃容納部5的軸方向一端面（相當於前蓋1 1部分）的形成 方向’爲比垂直面（重力作用方向）更朝向外殼1 0側傾斜 4〇°〜45°左右。亦即，比起塵埃容納部5的軸方向一端面的 上部’下部更朝向外殼1 0側接近。藉此，塵埃容納部5的 軸方向一端面及軸方向另一端面，以垂直面（重力作用方 向）爲基準’成爲倒八字型。藉此，使用者將塵埃容納部 5朝向上方提起時較不會卡到，使用者，可容易地將塵埃 容納部5從吸塵器本體1卸取下來。而，使用者，將塵埃容 納部5卸下後，持住凹陷部3 9，塵埃分離部4上方或是斜上 方朝向提起’可容易地將塵埃分離部4從吸塵器本體1卸取 下來。如第1圖所示，塵埃分離部4的軸方向一端面（相當 於入口管3部分）的形成方向，以垂直面（重力作用方向 )更朝向外筒6側傾斜爲佳。亦即，比起塵埃分離部4的軸 -118- 201103484 方向另一端面的上部，以下部更朝向外筒6側接近爲佳。 藉此，使用者將塵埃分離部4朝向上方或是斜上方提起時 不會卡到，使用者，可容易地將塵埃分離部4從吸塵器本 體I卸取下來。又，並不僅只使用者將塵埃分離部4卸取下 來之情形時，在將塵埃分離部4及塵埃容納部5作爲一體亦 即將該集塵裝置2從吸塵器本體1卸取下來時，由於集塵裝 置2的軸方向一端面及軸方向另一端面，以垂直面（重力 作用方向）爲基準，成爲倒八字型，故將集塵裝置2朝向 上方提起時不會卡到，使用者可容易地將集塵裝置2從吸 塵器本體1卸取下來。 於本體吸氣口 21，被插入有軟管接頭管20，可保持軟 管接頭管20。於本體吸氣口 21的一端，具備有墊片22。藉 此，可保持軟管接頭管20與入口管3的氣密性。於吸塵器 本體1的前方下端（集塵裝置2的下側），具備有用以支撐 腳輪的腳輪支撐部23。於吸塵器本體1內的後方上側，具 備有朝向吸塵器本體1的前後方向延伸的吸氣導管27。吸 氣導管27之延設方向一端的開口，爲與過濾器15相向。於 吸氣導管27之一端的開口附近，具備有輔助過濾器26。藉 此，可抑制電動送風機28吸入殘留於集塵裝置2外的塵埃 。吸氣導管27之延設方向另一端爲被封閉，吸氣導管27之 延設方向另一端附近的下部’亦即’電動送風機2 8側係作 爲吸氣導管27的排出口 27b而呈開口。於吸塵器本體1之吸 氣導管27的一端之開口的上部，於與過濾器15接觸之位置 ，具備有除去附著於過濾器15之塵埃的除塵裝置24。除塵 -119- 201103484 裝置24爲於迴轉體的外周具備有螺旋狀的彈簧（彈性體） 。除塵裝置24會因馬達或電線捲軸的拉出而迴轉，藉由螺 旋狀的彈簧撥彈過濾器1 5的過濾器構件79，將附著於過濾 器15之塵埃抖落。如上述般，由於過濾器15的波折方向爲 縱向方向，因此被抖落的塵埃會變得易於朝向重力作用方 向掉落。被從過濾器1 5抖落的塵埃，會蓄積於外殼1 0內。 藉此，可抑制過濾器1 5的網目阻塞，抑制空氣的壓力損失 的降低，抑制吸引力之降低。 如第1圖與第43圖所示，於吸塵器本體1內的後方下側 ，具備有產生吸引力之電動送風機28。電動送風機28，係 以電動送風機28的吸入口朝向上方之方式立放設置。電動 送風機28，是從吸入口 28a的面到與其吸入口 28 a之面的相 反面爲止爲最長。因此，藉由使電動送風機28的吸入口 28 a朝向上方地，將電動送風機28以立放方式設置，可以 縮短從軟管接頭管20到本體排氣口 30爲止之吸塵器本體1 的長度。在吸塵器本體1內，於電動送風機28的上部設置 有吸氣導管27，電動送風機28的吸入口 28a與吸氣導管27 的排出D27B是連結著。在本實施例中，將電動送風機28 設置於吸塵器本體1內之情形，是以：於電動送風機28的 上部具備有吸入口 28a，於電動送風機28的側部具備有排 氣口 28b之方式來設置。於吸塵器本體1內，於電動送風機 28的下游側且比電動送風機28更位於前側處，具備有連通 於電動送風機28的排氣口之排氣導管40。再者，於排氣導 管40的下游側且比排氣導管40前側處，具備有連通於排氣 -120- 201103484 導管40之過濾器29。排氣導管40與過濾器29，是藉由螺絲 等之固定手段所固定著。此乃藉由將排氣導管40與過濾器 29予以固定而可以保持排氣導管40與過濾器29的氣密，用 以使從電動送風機2 8排出的所有排氣通過過濾器29，並藉 由過濾器29使從電動送風機28排出的排氣能夠被過濾。過 濾器29，是在其斷面形狀呈大致四角形的框體內，形成有 被折成褶狀的過濾器構件。過濾器構件的波折方向以縱向 方向（重力作用方向）爲佳。過濾器2 9，例如，爲高密度 的 ULPA過濾器（Ultra Low Penetration Air Filter)。 ULPA過濾器’對於在額定風量下且粒徑爲0.15 // m的粒子 ，具備有99.9995%以上的粒子捕集率，且爲具有初期壓力 損失24 5P a以下的性能之空氣過濾器，並具備有比HEP A過 濾器的粒子捕集效率還高的粒子捕集效率。而，於吸塵器 本體1的後端面，具備有本體排氣口 30。 如第44圖所示，電線47於前端具備有插頭43。藉由將 插頭43插入位於房屋等之插座而取得電力。在使用充電式 吸塵器以外的電氣吸塵器時，若沒有將插頭43插入於插座 就無法使電動送風機2 8等動作。因此，電氣吸塵器在使用 時，在不會防礙操作之處設置電線捲軸4 1爲佳。以下，將 設置電線捲軸的處所稱之爲電線捲軸室42。若是以使插 頭43或是電線47可從吸塵器本體1的前部拉出之方式而於 吸塵器本體1的前部設置有電線捲軸室42之情形時，由於 插頭43或電線47成爲朝向行進方向拉出，所以在吸塵打掃 時不好操作。若是以使插頭43或是電線47可從吸塵器本體 -121 - 201103484 1的側面部或是上表面部拉出之方式而於吸塵器本體1的側 面部或是上表面部設置有電線捲軸室4 2之情形時也是在吸 塵打掃時不好操作。因而以使插頭4 3或是電線4 7可從吸塵 器本體1的後端面拉出之方式來將電線捲軸室42設置在吸 塵器本體1內的後部，藉此就不會成爲行進方向或是方向 轉換上的妨礙，而容易操作。在本實施例中，電動送風機 28與電線捲軸室42，是在吸塵器本體1內以相相鄰接之方 式所設置。又，電動送風機28與電線捲軸室42，是設置在 吸塵器本體1內之比集塵裝置2更後部處。如第54圖所記載 ，在本實施例中，電線捲軸室42之縱向方向的長度是比電 動送風機28之縱向方向的長度還要長，但比電動送風機28 和排氣導管40相加後之縱向方向的長度還要短。 過濾器29在吸塵器本體1內，是位在吸塵器本體1之縱 向方向大致中央部位置。又，從第1圖或是第43圖亦可明 瞭，在吸塵器本體1內，過濾器29是位在過濾器15的下方 位置。將吸塵器本體1橫放時，若是與吸塵器本體1之下表 面成爲平行的角度當作爲0°時，只要集塵裝置2的軸相對 於吸塵器本體1下表面比0°傾斜的話，集塵裝置2的側面圖 ，就會以集塵裝置2的軸作爲斜邊而成爲直角三角形。在 該集塵裝置2之側面圖中之直角三角形之高度方向的長度 ，只要比過濾器15之高度方向的長度還長的話，在集塵裝 置2之高度方向的長度與過濾器15之高度方向的長度就會 產生差異。若以使該差異形成於過濾器15的下方之方式將 過濾器15設置於集塵裝置2的話，則於過濾器15的下方會 -122- 201103484 形成出空間。過濾器1 5係位於吸塵器本體1內的縱向方向 大致中央部且是寬幅方向大致中央部位置，又由於寬幅亦 寬廣，所以於吸塵器本體1內，是無法將電線捲軸室42設 置於過濾器15的旁邊。又，由於從吸塵器本體1下表面至 過濾器15爲止的長度是比電線捲軸室42之高度方向的長度 還要短，所以是無法在過濾器15之下方設置電線捲軸室42 。藉由以上所述，將過濾器29設置在過濾器15之下所產生 的空間，而能夠增大過濾器29的面積。集塵裝置2的軸， 雖記載爲相對於吸塵器本體1下表面成傾斜，但此軸若無 傾斜時，就如第53圖，於過濾器15的下方就無法形成空間 。又，集塵裝置2的軸即使相對於吸塵器本體1下表面呈垂 直，還是會於過濾器15的下方產生空間，而能夠增大過濾 器29的面積。 如第1圖、第43圖所示，排氣導管40係設置在電動送 風機28與過濾器29之間。排氣導管40爲中空的構件，是由 :從電動送風機28的側部覆蓋下部的外周部分44 (在第42 圖朝右下對角線劃線部分）、以及從電動送風機28的排氣 口 2 8b周邊連通至過濾器29爲止之間的筒形狀通路部分48 所構成。外周部分44的形狀大致爲角柱狀，其直徑爲吸塵 器本體1後部之寬幅的約一半，且高度方向的長度是比電 動送風機28之高度方向的長度還短，外周部分44的上表面 具備有開口部44a，於外周部分44的側面具備有開口部44b 。在外周部分44的上表面與電動送風機28之間設有橡膠等 之墊片19，當取得排氣導管40與電動送風機28之間的氣密 -123- 201103484 性之同時，具有抑制電動送風機28使用時之振動的效果。 外周部分44側面的開口部44b係與電動送風機2 8的排氣口 28b相向。外周部分44上表面之開口部44a的大小是比電動 送風機28的直徑還大，外周部分側面開口部44b是比電動 送風機28的直徑還小。又，如第42圖所示，通路部分48是 由筒形狀的2個部分所構成。其中1個爲相對於一側面另一 側面呈傾斜部分（以下稱爲通路部分A45，是在第42圖中 爲劃橫線的部分），另1個爲一側面與另一側面成爲大致 平行的部分（以下稱爲通路部分B46，是在第42圖中朝右 上對角線劃線部分）。通路部分A45及通路部分B46皆具有 作爲開口部的入口。通路部分A4 5的入口（以下稱爲入口 A45a )係與外周部分側面開口部連結，通路部分A45的出 口（以下稱爲出口 A45b )係與通路部分B46的入口（以下 稱爲入口 B45a)連結，通路部分B46的出口（以下稱爲出 口 B45b )係與過濾器29連結。入口 A45a是比出口 A45b還 小，入口 B46a與出口 B46b大致相同的大小。入口 A45a與 外周部分側面開口部44b係設成相同的大小，又出口 A45b 與入口 B46a係設爲相同的大小。又，從入口 A45a至出口 A4 5B是止的長度是比從入口 B46a至出口 46B是止的長度還 長。此乃爲了防止吸塵器本體1之全長變長。又’在排氣 導管40的通路部分48內’與過濾器29連結的出口 B46b是比 與外周部分44連結的入口 A4 5 a還要寬廣。又，從通路部分 48的入口 A45a至出口 B46B是止的高度沒有改變地’通路 部分48的上表面與下表面成平行。於吸塵器本體1中’由 -124- 201103484 於從外周部分44至通路部分A45爲止是被配置在電線捲軸 室42的旁邊，通路部分B46與過濾器29是被配置在電線捲 軸室42的前面，所以從入口 B46a至出口 B46B是止的長度 若增長的話，則吸塵器本體1的全長也會增長該增長量。 排氣導管40，係具有連通從開口部44a至出口 B45b的通路 。排氣導管48較大意指著將排氣導管48的內部予以連通的 通路較大。在將吸塵器本體1橫放之情形時，從吸塵器本 體1的側面觀察通路部分A45時的圖（正面圖）與從吸塵器 本體1的後方觀察時的圖（側面圖）皆爲長方形，而從吸 塵器本體1的上方觀察時的圖（平面圖）爲梯形。通路部 分B 46的正面圖、側面圖、平面圖全都爲長方形。排氣導 管40的外周部分44與通路部分A45連結著，通路部分A45 與通路部分B46連結著。各別之連結部分以成爲平滑之方 式連結著。此爲用以使在各別的連結部分，不要產生排氣 氣流的紊亂或是無用的牽扯而實施的。於通路部分A45中 ，相對於其中一側面，另一側面是以大約傾斜40度至50度 之方式而構成。此爲具有：（通路部分）擴大用以使得能 夠配合過濾器2 9的大小之效果、除了用以使流速變慢之效 果外再加上（通路部分）擴大可避開配置在電動送風機28 旁之電線捲軸室42之效果。在本實施例中’電線捲軸室42 的平面圖爲長方形。電線捲軸室42的長邊與通路構件A45 之從電線捲軸室42開離之側的一側面大致成爲平行。通路 構件A45之接近電線捲軸室42之側的側面是從入口 A45 a到 出口 A45b以靠近電線捲軸室42之方式呈傾斜。通路部分 -125- 201103484 B46係具有：從電動送風機28之前到電線捲軸室42之前爲 止的寬幅。不將外周部分44與通路部分B46直接連結而於 中間夾隔而連結有作爲傾斜部分的通路部分A45，是有以 下的理由。若不設置傾斜部分而連結外周部分44與通路部 分B 4 6之情形時，寬幅就會急劇地從外周部分44的寬幅擴 開到通路部分B46的寬幅。此種情形時，從電動送風機的 排氣口 28b排出的排氣不能到達寬幅擴開的部分，會造成 減少了藉由增大過濾器29所產生的效果之虞。爲了避開此 種缺失而設成寬幅慢慢地擴開之構造，設成使排氣可易於 到達到過濾器2 9之寬幅的擴開部分之構造爲佳。爲了慢慢 地使寬幅成爲擴開之構造因而有通路部分A45，由設置此 構造所產生的效果係如上述所說明。在本實施例中，出口 A45b的大小雖是作成比出口 B46b的大小還小之構造，但並 非限定於此。也可以使出口 A45b之大小作成與出口 B46b的 大小相同程度的大小，作成使寬幅從外周部分44到過濾器 29爲止（從入nA45a到出口 B46B是止）慢慢地擴開之構 造。在本實施例中，雖是將通路部分A或通路部分B的正面 圖、側面圖、平面圖限定爲長方形或是梯形，但並非限定 於此。除此之外只要能夠顯現出通路部分40爲呈擴開構造 者，在正面圖、側面圖、平面圖即使是圓形、方形在效果 上也沒有問題。 爲了使吸塵器的排氣清靜，必須提高吸塵器的補塵性 能。爲此只要使用如ULP A過濾器般之粒子捕集率較高的 過濾器即可。不過，過濾器的粒子捕集率較高的話，反過 ⑧ -126- 201103484 來說就是過濾器的密度較高，也就是說壓力損失也較高， 其結果是增大阻塞的可能性。爲了減低壓力損失就必須增 大過濾器的表面積。將過濾器29製成褶狀就是用來增大表 面積。但是，若考慮要更進一步減低壓力損失時，就必須 要增大過濾器本身。若單純地要在吸塵器之中設置大的過 濾器雖是可能，但得避免因此而使得吸塵器本體變大。對 於不增大吸塵器本體而要在吸塵器本體後部設置大的過濾 器，將使得在吸塵器本體後部所設置的電線捲軸4 1成爲障 礙。因此，大的過濾器若能設置在沒有電線捲軸4 1之吸塵 器本體的中央部爲佳。話雖如此，若只是把過濾器安置於 中央就會造成本體變長。在本實施例中，如第1圖所示地 ，塵埃.分離部4與塵埃集塵部5在吸塵器本體1橫放時是相 對於地板面傾斜大約40°〜45°地設置於吸塵器本體1。此乃 藉由使塵埃分離部4與塵埃集塵部5分開用以防止吸塵器本 體的高度方向過大，藉此於塵埃分離部4與塵埃集塵部5的 下部形成空間。在此空間設置過濾器29，再者藉由將電動 送風機28直立設置以防止吸塵器本體1變長。又，由於 ULP A過濾器的寬幅比電動送風機28的寬幅還寬，所以連 通電動送風機28與ULP A過濾器的排氣導管40其幅寬是成 爲隨著從電動送風機28朝向過濾器29移行而變寬的構造。 正因爲排氣導管40其幅寬是成爲隨著從電動送風機28朝向 過濾器29移行而變寬，所以流速慢慢地變弱，而容易由過 濾器29進行垃圾的集塵。又，由於爲了使經由排氣導管40 之來自於電動送風機28的排氣可全部通過過濾器29而使電 -127- 201103484 動送風機28和排氣導管4〇和過濾器29呈密閉，所以全部的 排氣可通會過濾器29，而可以實現補塵性能高、且乾淨的 排氣。 其次，說明電氣吸塵器之操作時（使用時）之空氣流 向。第1圖中的箭頭，爲顯示空氣流向。使用者將電氣吸 塵器的電源ON時，電動送風機28會動作，而產生吸引力 。從軟管接頭管20吸入的空氣，爲通過入口管3，而流入 外筒6內，並碰撞凹陷部8而改向朝半徑方向，再者，於凹 陷部8之內筒7的外周端部處稍微改向朝圓周方向，再於引 導管38處改向朝圓周方向。其結果，空氣，以外筒6的軸 心爲中心而迴旋於外筒6。亦即，成爲迴旋流。藉由伴隨 空氣的迴旋產生之離心分離作用，含於空氣之較重的塵埃 會集中於迴旋流的外側。含於空氣之較輕的塵埃不僅於迴 旋流的外側，亦殘留在內側。不過，於一般家庭的掃除， 塵埃的大部分爲集中於迴旋流的外側，於迴旋流的內側是 不太殘存有塵埃。內筒7外的空氣爲與較重塵埃一同通過 外側流路35，並朝向集塵盒12流入。塵埃被集塵盒12捕集 ，並蓄積，再被吸引力壓縮。由於塵埃是藉由吸引力自動 壓縮，故不用煩勞使用者的手’即可保持很多的塵埃。空 氣爲通過集塵盒12的底面及上下左右面’到達過濾器15。 另一方面，迴旋流的內側空氣’爲從內筒7的貫通孔33流 入內筒7內。比貫通孔33還大的塵埃，不能通過貫通孔33 ，而殘留於內筒7外。內筒7內的空氣爲與較輕的塵埃及較 小的塵埃一同通過內側流路3 6 ’在外殼1 0內朝向集塵盒1 2 ⑧ -128- 201103484 的外部下側流入，而到達過濾器1 5。通過集塵盒1 2內的空 氣及沒有通過集塵盒12內的空氣，在過濾器15的前面合流 ，並通過過濾器1 5。在過濾器1 5，爲捕集較輕的塵埃及較 小的塵埃以及其他空氣所含的塵埃。通過過濾器1 5後而幾 乎不含塵埃的空氣，爲通過輔助過濾器並流入吸氣導管27 ，通過吸氣導管27的下部的開口而從電動送風機28的上部 的吸入口被吸入。從電動送風機2 8的側部的排出口被排出 的空氣，通過寬幅朝向過濾器29變寬廣的排氣導管40，而 到達過濾器29，並藉由過濾器29捕集在過濾器15所無法捕 集乾淨的塵埃。通過過濾器29之空氣，爲通過電動送風機 28的周圍或電線捲軸室（圖示省略）、吸塵器本體1的下 部之間隙等，然後從本體排氣口 30被朝向吸塵器本體1外 部排出。特別是過濾器29，由於具備有與使用於空氣清淨 機的過濾器相同程度或是其以上的集塵效率，所以從吸塵 器本體1被朝向外部排出的空氣，係被淨化成與空氣清淨 機相同程度或是其以上之程度。 於排氣導管40的下部設置有基板49。由於基板49是電 動送風機28的動作等，在進行電氣吸塵器的電氣性操作上 之重要的精密零件，所以若使塵埃附著於該基板49時恐有 引起不良後果之虞。基本上爲了不引起不良後果而會以罩 體等罩住，不過由於在本實施例中是使通過過濾器29後之 清淨化後的空氣通過基板49，所以更加減少引起不良後果 之虞。 於第2圖（A)，是顯示本發明之實施例之集塵裝置的 -129- 201103484 立體圖，於第2圖（B)，是顯示本發明之實施例之集塵裝 置的橫向斷面圖。使用者，藉由握持把手16將集塵裝置2 朝向上方提起，便可以從吸塵器本體1將集塵裝置2卸取下 來。不過，也可以將塵埃分離部4留在吸塵器本體1，而只 將塵埃容納部5從塵器本體1卸取下來。如第2圖（A )所示 ，從軸方向所觀察之塵埃分離部4之斷面的外廓形狀，大 致爲圓形狀。塵埃容納部5之斷面的外廓形狀，在前蓋11 的部分爲大致圓形狀，而前蓋11的部分以後則爲大致四角 形狀，且過濾器15的部分爲大致四角形狀。如第2圖（B) 所示，外殻10之軸方向一端的開口方向與外殻1〇的軸方向 另一端的開口方向並不在一直線上，而是有45°〜50°左右 的差異。亦即，塵埃容納部5的軸方向，是在比中間還些 許靠近前側’呈彎曲。上述曾說明過’集塵裝置2之軸方 向一端面（入口管3的部分）是稍微朝向下方向（重力作 用方向），集塵裝置2之軸方向另一端面（過濾器15的部 分）也是稍微朝向下方向（重力作用方向），集塵裝置2 之軸方向一端面與軸方向另一端面，是以垂直面（重力作 用方向）爲基準，由於成爲倒八字型形狀，所以在將集塵 裝置2朝向上方提起時比較不會勾卡住，因此使用者’可 以容易地將集塵裝置2從吸塵器本體1卸取下來。 於第3圖（A)，是顯示本發明之實施例的內筒及外筒 的立體圖，於第3圖（B)，是顯示本發明之實施例之內筒 內側的立體圖。外筒6的一端面’除了形成入口管3的部分 之外是呈封閉；外筒6的另一端面，是呈開口。內筒7 ’於 ⑧ -130- 201103484 圓筒部分的一端，具備有圓環狀的外延部34。如第3圖（A )所示，藉由從內筒7的圓筒部分朝向軸方向插入於外筒6 內，使外筒6之另一端面的外周端抵接於外延部34的外周 端，使內筒7形成於外筒6內。如第3圖（A)所示，入口管 3的開口方向與凹陷部8的開口爲相向。朝向凹陷部8之內 筒7之外周端部的開口方向爲大致向下，且引導管38之圓 周方向的開口方向，爲繞逆時鐘轉。又，引導管38之圓周 方向的開口方向，也可以繞順時鐘轉。還有，於外延部3 4 的上部，具備朝向軸方向貫通的孔，亦即外延部34的上部 是呈開口。開口的左壁面，是比右壁面還高。亦即，與引 導管38之圓周方向的開口方向相向之外延部34上部之開口 的壁面（左壁面）是比其他的壁面（右壁面）還要高。還 有，外延部34的表面，是成爲螺旋狀，並具有將空氣滑順 地引導至外延部34上部之開口的流路功能。如第3圖（B ) 所示，於內筒7內之上側大致半圓部分，具備有朝向內筒7 的內側並凹陷封閉的凹陷部3 9，下側大致半圓部分，係朝 向內筒7內呈開□。於集塵盒1 2在沒有塵埃蓄積之狀態下 ，內筒7外的空氣的流量比內筒7內的空氣的流量更多之情 形時，也可以比起內筒7內的開口面積更加大外延部3 4上 部的開口面積。相較於朝向內筒7內的開口，亦可作成凹 陷部39的區域更多，相較於凹陷部39 ’亦可作成朝向內筒 7內的開口的區域更多。而，使用者將手指放入凹陷部3 9 ，可容易地拿住塵埃分離部4或內筒7。 於內筒7的圓筒部由具有抗菌效果的金屬材料形成之 -131 - 201103484 情形時，首先，是在金屬的薄板，將直徑0.1 mm〜0.4 mm 左右的複數個貫通孔3 3予以蝕刻加工，其後，將兩端接合 作成圓筒形狀。貫通孔3 3亦可施以沖孔加工。作爲抗菌效 果的金屬材料，例如，有不鏽鋼、銀、銅等。不限於不鏽 鋼、銀、銅，只要爲含有銀或銅或是表面析出銀或銅之合 金即可。金屬的薄板的厚度爲lmm以下，而爲了提昇加工 性’以0.1mm〜0.5mm左右爲佳。於金屬薄板的厚度較薄 時’爲了提昇強度或真圓度，圓筒形狀的金屬薄板的軸方 向的兩端，用成形性佳的樹脂予以固定爲佳。具體上，於 具備有凹陷部8或引導管38之內筒7的大致圓形之一端部的 形狀以及具備有圓環狀的外延部34之內筒7的另一端部的 形狀所形成的形狀，設置圓筒形狀的金屬薄板’其後’藉 由將樹脂灌入模型，而嵌入成型。藉由嵌入成型之情形時 ’亦可不必將金屬薄板的兩端接合形成圓筒形狀。如此’ 可將具備有凹陷部8或引導管38之內筒7的大致圓形的一端 部以及具備有圓環狀的外延部34之內筒7的另一端部用樹 脂構成而僅內筒7的圓筒部分由金屬材料構成。藉由嵌入 成型，可將製造過程簡約化。 於第4圖（A)，爲顯示將本發明之實施例的塵埃容納 部5的前蓋1 1打開之狀態的立體圖’於第4圖（B ) ’爲將 本發明之實施例的塵埃容納部5的後部過濾器打開之狀態 的立體圖顯示。如第4圖（A)所示’前蓋Η以軸31爲支點 朝向下側方向轉動打開時，集塵盒1 2也以軸1 4爲支點朝向 下側方向轉動彈出。此時，集塵盒1 2 ’以軸1 3爲支點被分 -132- 201103484 割成上下。從塵埃容納部5彈出時之集塵盒1 2的開口，相 較於被收納於塵埃容納部5內時之集塵盒1 2的開口爲擴開 。藉此，可容易地刮落緊貼於集塵盒1 2之內面的塵埃。又 ，使用者，沿著集塵盒1 2的內面裝著纖維紙時，若將纖維 紙的端部用集塵盒1 2的開口部的框體與前蓋1 1的外周端夾 入，可抑制纖維紙移位或脫落。如第4圖（B )所示，過濾 器15以軸3 2爲支點朝向下側方向轉動打開。藉此，使用者 ，可容易地排出蓄積於外殼10內集塵盒12外部之塵埃，再 者》可容易地除去附著於過濾器1 5的外殼1 0側面之塵埃。 第5圖（A )，爲從塵埃容納部外側觀察本發明之實施 例的塵埃容納部5的前蓋之正面圖，且第5圖（B )，爲從 塵埃容納部內側觀察本發明之實施例的塵埃容納部5的前 蓋之正面圖。又，圖中的斜線部分，並非斷面，係顯示最 前面的表面。於前蓋11的下端，爲具備有可自由轉動地被 支撐於外殻10的軸31。前蓋，爲呈大致圓形。第5圖（A) 所示之斜線部分之外側的大致圓形部分，爲可抵接於塵埃 分離部4的軸方向另一端面的外周端。第5圖（A)所示之 斜線部分的內側的大致圓形部分，爲可抵接於塵埃分離部 4之內筒7的軸方向另一端面的外周端。在前蓋1 1的上側亦 即與軸3 1爲相反側之處，於斜線部分之外側的大致圓形部 分與內側的大致圓形部分之間，形成有外側流路3 5的開口 。外側流路3 5的表面側（塵埃容納部5外側）的開口位置 ，亦可在前蓋1 1的左右側或下側，不過，於將外側流路3 5 的背面側（塵埃容納部5內側）的開口位置作在前蓋1 1的 -133- 201103484 上側時，爲了縮短外側流路3 5的長度來減低空氣的壓力損 失，外側流路3 5的表面側的開口位置，亦以在前蓋1 1的上 側爲佳。另一方面’於內筒7的內側形成有內側流路3 6的 開口。於第5圖（A )的正面圖’爲內側流路3 6的開口面積 比外側流路3 5的開口面積大，不過’內筒7內的上側大致 半圓部分’因形成有凹陷部39’故內筒7外的空氣的流量 比內筒7內的空氣的流量更多之情形時’作爲實質的流路 面積者，內側流路3 6的開口面積爲比外側流路3 5的開口面 積小。又，斜線部分之外側的大致圓形部分及內側的大致 圓形部分間之沒有形成外側流路3 5的開口部分’爲被封閉 。第5圖（B )所示之斜線部分之外側的大致圓形部分’爲 抵接於外殻1〇的軸方向一端面的外周端及集塵盒12的開口 的外周端的一部分。如第5圖（B)所示，於比前蓋11的上 下方向中心線上側處，形成有外側流路3 5的開口。藉此’ 於電氣吸塵器停止時，可防止蓄積於集塵盒12之塵埃朝向 外側流路3 5及塵埃分離部4逆流。不過，於包前蓋1 1的上 下方向中心線的中央部，亦可形成外側流路3 5的開口。再 者，以形成覆蓋外側流路3 5之止回閥（圖示省略）爲佳。 藉此，更於電氣吸塵器停止時，可防止蓄積於集塵盒12之 塵埃朝向外側流路35及塵埃分離部4逆流。另一方面，於 前蓋1 1的下端附近，形成有內側流路3 6的開口。不過，內 側流路3 6的開口位置，相對於外側流路3 5的開口位置，可 爲下側’亦可爲左右側或是上側。又，內側流路36的開口 之上側的斜線部分，爲抵接於集塵盒1 2的開口之外周端的 -134- 201103484 下端。而，如第5圖（B )所示，於前蓋1 1的背面側（麈埃 容納部5的內側），外側流路3 5的開口面積爲比內側流路 36的開口面積還大。再者，如第5圖（A)及第5圖（B)所 示，外側流路3 5的另一端（背面側）之開口面積（第5圖 (B ))，爲比外側流路3 5的一端（表面側）之開口面積 (第5圖（A))大。亦即，外側流路3 5，爲從一端朝向另 —端擴開。另一方面，如第5圖（A )及第5圖（B )所示， 內側流路3 6的另一端（背面側）之開口面積（第5圖（B ) )，爲比內側流路3 6的一端（表面側）之開口面積（第5 圖（A ))還小。亦即，內側流路3 6，爲從一端朝向另一 端變窄。 於第6圖，爲顯示將本發明之實施例的塵埃容納部的 前蓋除去時之從塵埃分離部側觀察之正面圖。又，與第5 圖同樣，圖中的斜線部分，並非斷面，係顯示最前面的表 面。大致圓形的斜線部分，爲抵接於前蓋Π的外周端。如 第6圖所示，外殼10的軸方向一端面的開口的外周端，爲 抵接於集塵盒1 2的開口的外周端的一部分。又，如第6圖 所示，外殼10的軸方向一端面的開口的80%以上，爲集塵 盒12的開口所占據。而，外殼10的開口之集塵盒12之開口 以外的區域（剩下20%左右以下），爲與內側流路36的開 口相向，並連通於內側流路3 6。 第7圖，爲本發明之實施例的電氣吸塵器的槪觀圖。 電氣吸塵器，除了吸塵器本體1以外，爲具備有：吸入具 50、及接頭管（延長管）51、及操作管52、以及軟管54 ; -135- 201103484 上述吸入具50爲具備有吸口，上述接頭管（延長管）51， 其一端爲連通於吸入具50且可自由伸縮，上述操作管52， 其一端爲連通於接頭管51的另一端，並具備有使用者握持 用的把手53或操作按鈕/開關，上述軟管54，其一端爲連 通於操作管52的另一端，並於另一端形成有軟管接頭管20 。於吸塵器本體1的本體吸氣口 21可插入並保持軟管接頭 管20。又’於吸塵器本體1的兩側面具備有輪子55。 並且，藉由來自使用者對操作按鈕/開關的操作，將 電氣吸塵器的電源ON時，則電動送風機28會動作產生吸 引力。從吸入具50的吸口吸入空氣，便依序通過接頭管51 、操作管52、軟管54、軟管接頭管20，而流入吸塵器本體 〔實施例7〕 在實施例6中，是利用將設於電動送風機28之下游的 過濾器29設置在吸麈器本體1之縱向方向大致中央部，而 能夠取得增大過濾器29的面積，從電動送風機28連結到過 濾器29爲止的排氣導管40是設成從電動送風機28側朝向過 濾器29側增大的構造，但並非限定於此。如第47圖所示， 即使在吸塵器本體1內將過濾器29設置在比電動送風機28 或是電線捲軸室42還要後方時，只要採用增大從電動送風 機28連結至過濾器29爲止之較大的排氣導管40的構造，便 可以與實施例6相同樣地除去細微的塵埃，並能夠提供壓 力損失較小的電氣吸塵器。再者，於吸塵器本體1之縱向 -136- 201103484 方向大致中央部具有過濾器15或是集塵裝置2等’但由於 在吸塵器本體1內的後方並沒有該等裝置或構件’所以能 夠將過濾器29的大小也朝向高度方向增大。不過’對於將 過濾器29設置在吸塵器本體1的後方之情形時，由於吸塵 器本體1的全長變長，藉此電線捲軸室42與吸塵器本體1後 面的位置相距有過濾器2 9的厚度距離。在吸塵清掃時’爲 了不造成妨礙地可以從吸塵器本體1後面拉出插頭43或電 線4 7，就必須從電線捲軸室4 2到吸塵器本體1後端面爲止 設置通路。又，其他的構成係與實施例1相同。 〔實施例8〕 在實施例6中，是將通路部分A45的一側面設成與電線 捲軸室42的長邊部分大致平行，並使另一側面設爲從入口 A45a朝向出口 A45b變寬廣的構造，但並非限定於此。如第 48圖所示地，由於只要是從電動送風機28到過濾器29止的 通路部分48爲變寬廣的構造就能達到所謂減低壓力損失的 效果，所以即使是通路部分48的兩側面變寬廣的構造也可 以與實施例6相同樣地除去細微的塵埃，而能夠提供壓力 損失較小的電氣吸塵器。又，此情形時，在構造上是採取 :通過過濾器2 9後的排氣是與實施例6相同樣地通過電線 捲軸室4 2或是基板4 9的路徑，而其他的構造則與實施例6 相同。 〔實施例9〕 -137- 201103484 若能夠使用較大的過濾器就可以減低壓力損失。要是 在吸塵器的下部且是電動送風機28的下部有空間的話，就 能夠增大過濾器2 9所佔的面積。在實施例6至8中，是在電 動送風機28的下部設置有基板49。如第49圖所示地，藉由 將該基板49設置在集塵裝置2下部的空間就能在電動送風 機2 8的下部設出空間，並能夠在該處以使其面朝向上之方

6 in the insertion direction of the inner cylinder 7 toward the outer cylinder 6. Thereby, the airtightness can be sufficiently ensured, and the energy loss of the air can be reduced and the noise can be reduced. Fig. 36 (a) is a perspective view of the dust separating portion of the fifth embodiment of the present invention as seen from the front, and Fig. 17 (a) is a side view of the dust separating portion of the fifth embodiment of the present invention as seen from the right side. Figure. As shown in the enlarged cross-sectional view of Fig. 3(a), ribs (protrusions) 915 extending in the axial direction are formed in the step portion on the inner side of the axial end surface of the outer cylinder 7. The ribs 9.5 are plate-like in which the thickness is substantially uniform, and are partially curved along the step of the inner side of the end surface of the outer cylinder 7 in the axial direction. The height D4 of the rib 95 in the axial direction is, for example, about 5 to 6 mm. D4> (D3-D2). That is, the height of the rib 95 in the axial direction is larger than the stage difference. A range of step difference is formed with respect to the inner side of the end surface of the outer cylinder 7 in the axial direction, and the range in which the rib 95 is formed is shorter than the range in which the step is formed. On the other hand, in the inner side of the axial end surface of the outer cylinder 7, the rib 95 is formed in a portion corresponding to the front end portion of the inner cylinder 6 in the axial direction, although no step difference is formed. The rib 95 is also bent along the front end portion of the inner cylinder 6 in the axial direction. Therefore, the rib 95 is a part of the inner end surface of the outer tube 7 in the axial direction from a portion corresponding to the front end portion of the guide tube 38 in the axial direction, to a portion corresponding to the front end portion of the inner cylinder 6 in the axial direction. Some of them are formed continuously. However, the ribs 95 may not be formed on the portion corresponding to the front end portion of the inner cylinder 6 in the axial direction. The range in which the ribs 95 are formed may be formed at least above the upper and lower centers of the inner cylinder 7. As shown in the enlarged cross-sectional view, the inner peripheral surface of the rib 95 is assembled when the inner tube 6 and the outer cylinder 7 are combined so that the front end portion of the guide tube 38 in the axial direction can abut against the step difference. The outer peripheral surface of the end portion of the guide tube 38 in the axial direction and the outer peripheral surface of the axial end portion of the inner tube 6 are opposed to each other (preferably, abutting). The rib 95 also has a sealing function between the inner side of the axial end surface of the outer cylinder 7 and the front end portion of the guide tube 38 in the axial direction and the axial end portion of the inner cylinder 6, so that the phase difference is formed only. It can reduce the energy loss of the air or reduce the noise. Also, as long as the ribs 9 5 are formed, no stage difference can be formed. Fig. 3 is a perspective view of the inner cylinder of the fifth embodiment of the present invention as seen from the inner side of the extension portion. As shown in Fig. 35 and Fig. 36 (a) and Fig. 37, ribs (protrusions) 916 extending in the axial direction are formed on the lower side of the axial end portion of the inner cylinder 6. In the manner shown in Fig. 3(a), the ribs 96 have a substantially trapezoidal shape when viewed from the front, and the width of the ribs 96 gradually decreases as approaching toward the front end side in the axial direction. The rib 96 is bent along the front end portion of the inner cylinder 6 in the axial direction. As shown in Fig. 35, the thickness of the bottom side of the rib 96 is slightly smaller than the thickness D1 of the tip end portion of the cylindrical portion 57 in the axial direction, but may be equal. As shown in Fig. 35, the thickness of the bottom side of the rib 96 gradually decreases as it approaches the front end side in the axial direction. The rib 96 has a guiding function when the inner cylinder 7 is housed in the outer cylinder 6. On the other hand, as shown in Fig. 36 (b), the lower side of the inner side of the front end portion of the outer tube 6 in the axial direction and the lower side of the inner side of the inlet pipe 3 are formed to have a shape corresponding to the shape of the rib 96. Shaped snap hole 9 7. The engaging hole 197 is formed at a position corresponding to the rib 96 when the inner cylinder 7 is attached to the outer cylinder 6. However, in order to make the ribs 96 easy to insert, the engaging holes 97' are preferably slightly larger than the ribs 96 from -101 to 201103484, and the engaging holes 97 are closed holes. The axial direction bottom side (opening side) of the engaging hole 97 is preferably larger than the axial end side (closed side) of the engaging hole 97 so that the opening area is large. That is, the bottom side of the engaging hole 97 in the axial direction is preferably wide and thick. When the user holds the inside or the outside of the recessed portion 39, the upper side of the inner cylinder 7 is also the upper side with respect to the user, and the lower side of the inner cylinder 7 is also the lower side with respect to the user. When the user holds the inner cylinder 7 in the outer cylinder 6 by holding the inner side or the outer side of the recessed portion 39 by hand, the rib 96 located on the lower side is inserted into the engaging hole 97 due to the circumferential direction or the left and right. Since the relative position of the inner cylinder 7 and the outer cylinder 6 has been positioned, the upper side of the inner cylinder 6 can be easily inserted into the outer cylinder 6 thereafter. Thereby, the positional deviation of the relative elasticity of the inner cylinder 7 and the outer cylinder 6 can also be suppressed. Further, it is possible to suppress the inner cylinder 7 from being floatingly mounted with respect to the outer cylinder 6, or being bent and mounted. In particular, since the width and thickness of the ribs 96 on the distal end side in the axial direction of the insertion direction are small, the width and thickness of the bottom side of the engagement hole 97 in the axial direction are large, so that the user even the ribs 96 and the engagement holes are provided. When the relative position of 97 is slightly deviated, the rib 96 may be inserted into the engaging hole 97. Further, the engaging hole 97 may be formed in the axial end portion of the inner cylinder 7, and the rib 96 may be formed inside the front end portion of the outer cylinder 6 in the axial direction. As shown in Fig. 35, Fig. 36 (b), and Fig. 37, on the lower side of the outer peripheral surface of the spacer 9 of the inner cylinder 7, a projecting convex portion 98 is formed on the outer peripheral side. The amount of protrusion of the convex portion 98 is about 1 mm. As shown in Fig. 35, the convex portion 98 is preferably formed to extend in the axial direction portion which is enlarged in the radial direction among the outer peripheral surfaces of the spacer 9. The convex portion 98 is preferably made of a hard material which is harder than the spacer 9 from 8 to 102 to 201103484. However, it may be integrally formed of the same material as the spacer 9. On the other hand, as shown in Fig. 36(b), the lower side of the inner circumferential surface of the outer cylinder 6 forms a concave portion 9 9 which is recessed toward the outer circumferential side. The recess 9 9 is formed to correspond to the position of the convex portion 98 when the inner cylinder 7 is attached to the outer cylinder 6. The recess 9 9 ' is provided in a shape corresponding to the convex portion 98. The projections 98 are closed holes. When the user holds the inner cylinder 7 in the outer cylinder 6 by holding the inner side or the outer side of the recessed portion 39, the convex portion 98 positioned at a lower position than the rib 96 is fitted into the concave portion. 99, then, the rib 96 is inserted into the engaging hole 97, and since the relative position of the inner cylinder 7 and the outer cylinder 6 in the circumferential direction or the left-right direction has been positioned, the upper side of the inner cylinder 6 can be easily inserted later. Inside the outer cylinder 6. Thereby, the relative positional deviation of the inner cylinder 7 and the outer cylinder 6 can be suppressed as compared with the case where only the rib 96 and the engaging hole 97 are formed. Further, it is possible to suppress the inner cylinder 7 from being floatingly mounted with respect to the outer cylinder 6, or being bent and mounted. Further, since the convex portion 98 is formed on the outer circumferential surface of the spacer 9 of the inner cylinder 7, the concave portion 99 is formed on the inner circumferential surface of the outer peripheral wall of the outer cylinder 6, so that it is also relatively resistant to the axial direction. Therefore, by the convex portion 98 and the concave portion 99, it is possible to suppress the inner cylinder 7 when the user holds the inner side or the outer side of the recessed portion 39 in a state where the inner cylinder 7 is housed in the outer cylinder 6. The situation of falling off from the outer tube 6. Further, the concave portion 99 may be formed on the outer circumferential surface of the spacer 9 of the inner cylinder 7, and the convex portion 98 may be formed on the inner circumferential surface of the outer peripheral wall of the outer cylinder 6. The surface of the lip portion 68, the lip portion 69, and the spacer 9 may be embossed or formed with fine irregularities. Alternatively, a lubricant may be applied to the surfaces of the lip portion 68 and the lip portion 69, and the -103-201103484 spacer 9. As the lubricant, for example, a fluorine-containing material can be used. Alternatively, the lip portion 68, the lip portion 69, and the spacer 9 may be mixed with fluorine. Thereby, it is possible to prevent the lip portion 68 and the lip portion 69 from being fixed to the spacer receiving surface 76 and the spacer receiving surface 77 to be difficult to separate, or to prevent the spacer 9 from being fixed to the inner circumference of the outer peripheral wall of the outer cylinder 6 It is difficult to separate. As long as it is possible to suppress the lip portion 68 and the lip portion 69 from being fixed to the spacer receiving surface 7 6 and the spacer receiving surface 7 7 or to prevent the spacer 9 from being fixed to the inner peripheral surface of the outer peripheral wall of the outer tube 6, It can be used without being limited by the above embodiments. Fig. 3 is a cross-sectional view of the dust accommodating portion of the fifth embodiment of the present invention as seen from the side. Fig. 39 is a front elevational view of the front cover of the fifth embodiment of the present invention as seen from the inside of the dust containing portion. As shown in Fig. 3, a rib 104 having a plate shape extending in the axial direction is formed in the outer flow path 35 of the front cover 11. The rib 1〇4 extends in the axial direction from the front end to the rear end of the front cover 11. As a result, the outer flow path 35 is formed on the upper side of the rib 1 〇 4, and the flow path is not formed on the lower side of the rib 1 〇 4 . The flow path cross section of the outer flow path 35 is narrowed in the upward direction. As long as the dust can be prevented from accumulating on the lower side of the ribs 104, the ribs can also be used! The crucible 4 is formed into a substantially L-shaped shape so that the lower side of the rib 104 is a closed space that does not communicate with the dust collecting case 12. In Fig. 39, since the ribs 104 are concealed inside the check valve 1 〇 3, they are indicated by dotted lines. The wide width in the left-right direction of the rib 1 〇 4 as shown in Fig. 39 is a width which can reach the left-right direction of the outer flow path 35. By the ribs 1 〇 4, it is possible to suppress the dust accumulated in the dust collecting box 12 from being scattered from the outer flow path 35. Further, by the ribs 〇4, the airflow 62 flowing from the outer channel 35 of the 8-104-201103484 is increased in the upward direction, that is, the upper wall surface of the dust box 12, so that the swirling force of the airflow 62 can be increased. , to improve the separation of air and dust. As shown in Fig. 39, at the outlet end of the outer flow path 35, a check valve 103 is formed, which covers only the outer side flow path 35 formed on the upper side of the rib 104. Exit opening. Further, the check valve 103 is rotated toward the dust box 12 with the upper end serving as a fulcrum. The check valve 103 is preferably made of an elastic material such as rubber. By the check valve 103, dust accumulated in the dust collecting case 12 can be prevented from being scattered from the outer flow path 35. Fig. 40 is a front elevational view of the dust accommodating portion 5 of the fifth embodiment of the present invention as seen from the front side in the axial direction. It is the state in which the front cover 1 1 has been closed. Fig. 4 is a cross-sectional view of the dust collecting device 2 of the fifth embodiment of the present invention as seen from the upper side. As shown in Fig. 40, a through hole 105 for penetrating the front wall of the front cover 11 is formed on the left side of the front wall of the front cover 11. The through hole 105 is formed between the spacer receiving surface 76 and the spacer receiving surface 77 in the left side of the front cover 11. The through hole 105 has a diameter of 3. 4mm or so. If the through hole 105 is too large, the suction work efficiency (attractive force) of the cleaner body 1 is lowered, and if the through hole 105 is too small, an appropriate amount of outside air cannot be sucked from the through hole 105. The flow path area of the through hole 105 is preferably determined by the relationship with the suction work efficiency (attraction force) of the cleaner body 1. As shown in Fig. 41, the through hole 105 communicates with the outside (atmosphere) of the front cover 11. That is, the through hole 105 penetrates the front wall of the front cover 11 and is opened to the inside of the cover 1 1 before being connected to the outer flow path 35. The inner side of the cover 1 1 before being in communication with the outer flow path 35 is a gap from the side wall and the rear wall of the front cover 1 1 and communicates with the outside. -105-201103484 As shown in Fig. 41, the through hole 105 is opened in the state where the dust separating portion 4 is coupled (attached) to the dust containing portion 5: the lip portion 68 and the lip portion 69 are opened. Space between. The left side of the front wall of the front cover 1 is located at the downstream side of the airflow 62 in the outlet end of the inner cylinder 7 in the outer flow path 35. Further, as shown in Fig. 41, when the electric blower 28 operates to generate an attractive force, the space between the lip portion 68 and the lip portion 69 becomes a negative pressure, and the air flow of the outside air 1 〇 6 passes through the front cover 1 from the outside. The gap between the side wall and the rear wall of 1 passes into the inner side of the cover 1 1 before being communicated with the outer flow path 35, and then flows into the lip portion 68 and the lip portion 69 through the through hole 105 of the front wall of the front cover 11. Space between. Then, the air flow 106 of the outside air merges with the airflow 62 through the portion 100 on the inner peripheral side of the terminal of the outer flow path 35, and flows into the outer flow path 35. That is, in Fig. 3, the air flow 6 2 does not flow from the outlet end of the inner tube 7 of the outer flow path 35 to the lip portion through the inner peripheral side portion 100 of the terminal end of the outer flow path 35. The space between the 68 and the lip portion 69, and the flow from the space between the lip portion 68 and the lip portion 69 and then through the portion 100 of the inner peripheral side of the terminal end of the outer flow path 35 flows into the outer flow path 3 5 The outside air at the outlet end of the inner cylinder 7 merges. Therefore, the through hole 105' can suppress the dust contained in the air current 62 from being caught by the portion 100 on the inner peripheral side of the terminal end of the outer flow path 35. Further, the position or shape of the through hole 105 is not limited to the above, and the lip portion 68 and the lip portion 69 on the downstream side of the air current 62 may be provided at the outlet end of the inner tube 7 at the outer flow path 35. The space between the space and the outside can be connected. For example, the through hole 1 〇 5 or the slit (long hole) may be formed in the lip portion 68.

When the electric vacuum cleaner is in use, the vacuum cleaner body 1 is placed horizontally, and in the stored state, the cleaner body 1 is preferably placed vertically. When the electric vacuum cleaner is in use, the body suction port 21 side is the front side (upstream side), and when the body exhaust port 30 side is the rear side (downstream side), when the electric vacuum cleaner is in use, the body suction port 21 is in use. The main body exhaust port 30 is substantially horizontal with respect to the floor (the vacuum cleaner body 1 is horizontally placed), and the electric vacuum cleaner is in the stored state, so that the body suction port 21 is in the upper side of the gravity action direction, so that the body exhaust port 30 is gravity. The lower side of the direction (the vacuum cleaner body 1 is placed upright).

The side is referred to as the rear direction of the cleaner body 1, and is referred to as the longitudinal direction of the cleaner body 1 so as to span the front and rear directions of the cleaner body 1. Further, in the present embodiment, when the cleaner body 1 is placed horizontally as shown in Fig. 43, the handle 16 side is provided as the upper direction of the cleaner body 1, and the wheel 55 side is provided as the cleaner body 1. The direction is referred to as the height direction of -107-201103484 of the cleaner body 1 in the upward direction from the upper direction of the cleaner body 1. Further, in the present embodiment, when the cleaner body 1 is placed horizontally as shown in Fig. 44, it is called from the wheel 55 which is located on one side of the wheel 5 5 on both sides of the cleaner body 1 to the other wheel 55. It is the width direction of the cleaner body 1. First, the configuration of the cleaner body 1 will be described. The dust collecting device 2 that collects dust from the inhaled air is detachably disposed on the front side of the cleaner body 1. When the longitudinal direction (axial direction) of the dust collecting device 2 is used as the direction of gravity action, the height of the cleaner body 1 becomes high. On the other hand, the closer the axial direction of the swirling flow in the dust collecting device 2 (the axial direction of the dust collecting device 2) to the direction of gravity action, the greater the separation effect by the centrifugal separation action, and the swirling effect in the dust collecting device 2 If the axial direction of the flow exceeds 45° with respect to the direction of gravity action, the separation effect by centrifugal separation is extremely lowered. Here, in order to reduce the height of the cleaner body 1 and to suppress the decrease in the separation effect by the centrifugal separation, in the present embodiment, the axial direction of the dust collecting device 2 is set to 40° to 45 with respect to the direction of gravity action. ° or so. However, in order to increase the separation effect by centrifugal separation, the axial direction of the dust collecting device 2 may be set to be less than 40° with respect to the direction of gravity action (for example,). Instead of disposing the dust separating portion (the turning portion) 4 on the lower side and the dust containing portion 5 on the upper side, the dust separating portion 4 may be disposed on the upper side and the dust containing portion 5 may be disposed on the lower side. In this case, it is preferable that the inlet pipe 3 is continuous with the circumferential surface of the front end portion in the axial direction of the dust separating portion 4. The dust collecting device 2 is provided with a dust separating unit 4 that separates dust from a heart separation operation (cyclone type) from -108- 8 201103484, and a dust separation unit 4 that is housed and separated by dust. The dust containing portion 5 of the dust separated by the portion 4. The dust separating portion 4 and the dust containing portion 5 are arranged in the axial direction of the dust collecting device 2, and are connected to each other in the respective axial end portions. In other words, the dust separating unit 4 is disposed on the front side of the cleaner body 1, and the dust containing unit 5 is disposed on the rear side of the cleaner body 1 on the rear side of the dust separating unit 4. The dust separation unit 4 and the dust accommodation unit 5 are connected to each other so that the user can easily separate the dust separation unit 4 from the dust accommodation unit 5. At the front end of the cleaner body 1, a tubular body suction port 21 is provided. A part of the front end surface of the dust separating portion 4 in the axial direction is an opening, and the opening is connected to the inlet pipe 3. Here, the front end surface of the dust separating portion 4 in the axial direction may be connected to the inlet pipe 3, and the circumferential surface of the front end portion in the axial direction of the dust separating portion 4 may be connected to the inlet pipe 3. The dust separating unit 4 is an outer cylinder 6 having a substantially cylindrical shape having a hollow shape, and a hollow cylindrical inner cylinder 7 which is concentric with the outer cylinder 6 and is enclosed in the outer cylinder 6. In order to suppress the deviation of the axial direction of the swirling flow from the direction of gravity due to gravity, the separation effect by the centrifugal separation is lowered, and when the axial direction of the dust separating portion 4 is inclined with respect to the direction of gravity action, The axial center of the inner cylinder 7 can be deviated toward the lower side with respect to the axial center of the outer cylinder 6. As shown in Fig. 3(A), the one end surface (front end surface) of the outer cylinder 6 is closed except for the opening of the inlet pipe 3, and the other end surface (rear end surface) of the outer cylinder 6 in the axial direction is closed. 'Being an opening. The outer cylinder 6 is preferably formed of plastic or resin which is transparent or translucent -109-201103484 for the user to see that dust is accumulated or that the dust accumulated in the sensor provided outside the outer cylinder 6 is perceived. One end surface (front end surface) of the inner cylinder 7 in the axial direction is closed, and the other end surface (rear end surface) of the inner cylinder 7 in the axial direction is an opening. As shown in Fig. 3(A), a recessed portion 8 which is recessed toward the inner side in the axial direction of the inner cylinder 7 is formed at the center of the closed portion of the one end surface in the axial direction of the inner cylinder 7. The inlet pipe 3 is a closed portion which is one end face in the axial direction of the inner cylinder 7, that is, the recessed portion 8 faces each other. As shown in Fig. 3(A), a part of the recessed portion 8 reaches the outer peripheral end of the inner cylinder 7. In order to reduce the pressure loss of the air, the opening direction of the recessed portion 8 is preferably toward the lower side. However, the opening direction of the recessed portion 8 may be an upward direction or a lateral direction. As shown in Fig. 3(A), at the outer peripheral end portion of the inner cylinder 7 of the recessed portion 8, the recessed portion 8 is not inclined straight toward the radial direction of the inner cylinder 7, but is slightly inclined toward the circumferential direction. As shown in Fig. 1, the depth of the recessed portion 8 in the axial direction is approximately half of the length of the cylindrical portion of the inner cylinder 7 in the axial direction. However, the depth of the recessed portion 8 in the axial direction may be substantially the entire length of the axial direction of the cylindrical portion of the inner cylinder 7. In this case, the opening of the recessed portion 8 is formed over a portion of the circumferential surface of the inner cylinder 7 over substantially the entire length of the cylindrical portion of the inner cylinder 7. Further, a guide tube 38 is connected to the outer peripheral end portion of the recessed portion 8. The guide pipe 38 has a substantially 1/4 circular cross section and is formed along the outer circumferential surface of the inner cylinder 7, and the outer circumferential surface of the inner cylinder 7 also forms a part of the inner wall surface of the flow path. The guide tube 38 is formed on the outer circumferential surface of the inner cylinder 7 by about several cm in the circumferential direction. Therefore, the air 'inflow from the inlet pipe 3 toward the axial direction is changed to the radial direction by the recessed portion 8', and the outer peripheral end portion of the inner cylinder 7 of the recessed portion 8 is slightly changed toward the circumferential direction, and then guided. The tube 38 is redirected toward the circumferential direction. Further, the depressed portion 8 is preferably formed not by the unevenness but by the curved surface. -110- 8 201103484 By this, the pressure loss can be continuously suppressed while the air is sufficiently swirled. Guide tube 3 8, even if it does not matter. An extension portion 34 that extends toward the outer tube 6 is formed on the outer circumference of the other end surface (rear end surface) in the axial direction of the inner tube 7. That is, as shown in Fig. 3(A), the other end surface (rear end surface) of the inner cylinder 7 in the axial direction is an annular shape which is opened inside the inner cylinder 7. As shown in Fig. 3(A), a part of the circumferential direction of the extension portion 34 is an opening. By this opening, the air ' outside the inner cylinder 7 can flow into the dust accommodation portion 5. The inner cylinder 7 is capable of inhibiting the growth of bacteria by a metal containing an antibacterial action (for example, silver, copper) or an antibacterial substance (for example, silver or copper), or a metal coated with the above substance (for example, stainless steel). ) is better. However, the inner cylinder 7, which comprises the cylindrical portion, may also be composed of a resin. Further, as shown in FIG. 3(A), the inner tube 7 is inserted from the other end surface of the outer tube 6 in the axial direction toward the axial direction, and is brought into contact with the inner circumference of the outer peripheral end outer tube 6 of the extension portion 34. As a result, the other end surface of the outer cylinder 6 in the axial direction is closed. The outer tube 6 and the inner tube 7 are connected in such a manner that the outer tube 6 and the inner tube 7 can be easily separated by the user. A plurality of through holes 33 are provided in the circumferential surface of the inner cylinder 7. The inner cylinder 7 is provided with a filter function by a plurality of through holes 33. With the through hole 33, the coarser garbage does not flow into the inner cylinder 7, and the air can flow from the outer side of the inner cylinder 7 toward the inner side of the inner cylinder 7. It is also different depending on the inhalation force. However, the weight of the weight of one yen or more (about 1 gram) cannot be sucked up from the outer tube 6, and it may remain in the outer tube 6. By connecting the outer cylinder 6 and the inner cylinder 7 so that the user can easily separate the outer cylinder 6 from the inner cylinder 7, the user can easily separate the outer cylinder 6 and the inner cylinder 7, and can be easily discharged. The garbage accumulated in the outer cylinder 6 can be easily removed from the hair or batt of the through hole 33 of the inner cylinder 7 of the -111 - 201103484. In order to maintain the airtightness of the joint portion of the dust separating portion 4 and the dust containing portion 5, the gasket 9 is provided on the other end surface of the inner cylinder 7 in the axial direction. The spacer 9 is provided not only on the extension portion 34 but also in the axial direction of the inner cylinder 7. Therefore, the inner side of the inner cylinder 7 is not completely hollow, and there is a part of the closed space by the gasket 9. Further, a recessed portion 39 which is recessed toward the inner side in the axial direction of the inner cylinder 7 is formed in a portion of the spacer 9 which protrudes toward the inner side of the inner cylinder 7. The recessed portion 39 has a function of having a handle. Thereby, the user inserts a finger into the recessed portion 39, and the dust separating portion 4 or the inner cylinder 7 can be held. A part of the upper side of the extension portion 34 is an opening and communicates with the outer flow path 35 of the front cover 11. That is, it is the inner side of the outer cylinder 6, and is the outer side of the cylindrical portion of the inner cylinder 7, and is the outer flow path 35 that communicates with the front cover 11. As shown in Fig. 3(A), the wall surface in the circumferential direction of a part of the opening on the upper side of the extension portion 34 is higher in the circumferential direction on the side facing the opening of the guide tube 38, and is guided in the circumferential direction. The wall surface on the open side of the tube 38 is preferably lower. For example, when the dust separating portion 4 is viewed from the front, the opening direction of the guide tube 38 is a counterclockwise direction, and the wall surface on the left side in the circumferential direction of the opening of a part of the opening on the upper side of the extension portion 34 is high. The wall on the right side is lower. In other words, a part of the upper side of the extension portion 34 is in the opening direction, so that the circumferential direction of the extension portion 34 is less than one minute of the outer circumference of the inner cylinder 7, and is spirally shifted. Therefore, the swirling flow outside the inner cylinder 7 hits the upper wall surface of the opening on the upper side of the extension portion 34, and the wall surface of the opening is smoothly changed toward the axial direction, and the dust contained in the swirling flow is also easy. The dust accommodation portion 5 flows toward the dust. On the other hand, the inner side of the inner cylinder 7 is the inner flow path 36 that communicates with the front cover 11. 8 - 112 - 201103484 The dust accommodating portion 5 is a hollow outer casing 1 having an axial end surface (front end surface) and an axially opposite end surface (rear end surface) and having a substantially inverted triangular shape in cross section. Hey. The one end surface ′ of the outer casing 1 轴 is closed by the cover 11 before being opened and closed. The lower end portion of the front cover 1 is provided with a shaft 31 which is supported by the lower end portion of the outer casing 10. The front cover 11 is pivotable forward and backward in the axial direction of the casing 10 with the shaft 31 as a fulcrum. On the side of the outer casing 10 at the upper end portion of the front cover 11, there are claws protruding. On the other hand, on the front upper portion of the casing 10, there is provided a button 17 (which may be a control lever) that the user can press, and a button 1 (bar) extending toward the front side of the casing 10 is coupled to the button 17. 18. One end of the communication rod 18 is connected to the button 17, and the other end of the communication rod 18 is formed as a claw. The claw at the other end of the rod 18 is conveyed to the claw that can be engaged with the upper end portion of the front cover 11. In a state where the outer casing 10 is closed with the front cover 11, the claw of the other end of the communication rod 18 is engaged with the claw of the upper end portion of the front cover 11, and the front cover 1 1 can be prevented from being opened. Then, if the user presses the button 17 7 , the communication bar 18 slides toward the front side (also can be rotated toward the upper side), and the card of the other end of the bar 18 and the claw of the upper end portion of the front cover 11 are transferred. The assembly is released, and the front cover 11 can be opened from the outer casing 10 by gravity. The direction in which the handle 16 is formed is horizontal, and the normal direction of the one end surface of the outer casing 10 (corresponding to the portion of the front cover 11) is inclined by 45 to 50 with respect to the horizontal direction. That is, when the user holds the handle 16 to lift the dust containing portion 5, the one end surface of the outer casing 10 in the axial direction (corresponding to the portion of the front cover 11) is directed downward (the direction of gravity action). Therefore, the front cover 11 can be opened from the outer casing 1 by gravity. Further, as will be described later, the dust box (dust collecting container) 12' is pushed by the spring (elastic body) to be ejected toward the front side of the casing 10 - 113 - 201103484, and is pressed by the dust box 12 The rear cover 11 is rearward, so that when the user presses the button 17, the front cover 1 can be smoothly opened from the outer casing 10 by the pressing force of the dust box 12. The other end surface of the outer casing 10 in the axial direction is closed by a filter 15 that can be opened and closed. The lower end portion of the filter 15 is provided with a shaft 32 which is supported by the lower end portion of the outer casing 10. The filter 15 is pivoted forward and backward in the axial direction of the casing 1 with the shaft 32 as a fulcrum. The filter 15 is formed in a frame having a substantially quadrangular cross-sectional shape, and is formed with a filter member 79 which is folded into a pleat shape. As shown in Fig. 4(B), the direction of the waviness of the filter member 79 is preferably in the longitudinal direction (the direction of gravity action). The filter 15 is, for example, a High Efficiency Particulate Air Filter. The so-called HEP A filter has a particle size of 〇·3 // m relative to the nominal air volume. The particle collection rate of 9 7% or more is an air filter having an initial pressure loss of 245 Pa or less. A spacer 25 may be provided on the opposite side of the outer casing 10 of the filter 15. By the gasket 25, the airtightness of the other end surface of the dust containing portion 5 in the axial direction and the cleaner body 1 (particularly, the inlet of the suction duct 27) can be maintained. Further, the shaft 31 and the shaft 32 may be shared. Further, the 'shaft 32' is not provided at the lower end portion of the filter IS, and may be provided at the upper end portion of the filter 15. In the outer casing 10, the dust box 12 is wrapped. The shape of the dust box 12 may be a box shape in which the opening is open, a box shape or a container shape, or a bucket shape. That is, the dust collecting case 12 has a shape that is recessed toward the opposite side to the opening. The cross-sectional shape of the dust collecting box 12 may be substantially quadrangular, or may be substantially circular or substantially triangular. The cross-sectional shape of the dust box 12 from 8 to 114 to 201103484 is preferably reduced from the opening surface to the bottom surface. As a result, since the sectional area is expanded toward the side (opening side) where the dust is discharged, the user can easily discharge the dust accumulated in the dust collecting case 12. The shape of the dust box 12 is formed by a frame (bracket). It is preferable that the bottom surface and the upper, lower, left and right surfaces other than the opening surface of the dust collecting case 12 are covered or adhered to a mesh member made of metal or nylon. The airflow is ensured not only on the bottom surface of the dust box 12 but also on the upper and lower sides, and even if dust accumulates on the bottom surface of the dust box 12, the pressure loss of the intake air is reduced, and the decrease in the suction force can be suppressed. . The mesh member has air permeability and a filter function for trapping dust. As long as it is ventilated and has a filter function for collecting dust, the mesh member may be a disposable fiber paper instead of the mesh member, and the mesh member and the fiber paper may be combined. For example, the user may also load fiber paper on the mesh member. The opening surface of the dust collecting case 12 is aligned with the opening surface of the one end surface (front end surface) of the outer casing 1 in the axial direction. That is, the opening direction of the dust collecting case 12 is the same as the opening direction of the end surface of the outer casing 10 in the axial direction. As shown in Fig. 6, the upper half of the outer peripheral end of the opening surface of the dust collecting case 12 is the inner peripheral surface of the one end surface in the axial direction of the outer casing 1 , and the opening surface of the dust collecting case 12 is The lower side of the outer peripheral end is about half, and does not abut against the inner peripheral surface of the one end surface of the outer casing 10 in the axial direction. The dust box 12 is provided with a shaft 14 at a lower portion thereof. The shaft 14 is supported within the casing 1〇. Therefore, the shaft 14 at the lower portion of the dust box 12 is a fulcrum and can be rotated forward and backward toward the axial direction of the casing 1 。. Thereby, when the front cover 1 is opened from the dust accommodating portion 5, a part of the gravity dust box 12 can be ejected from the dust accommodating portion 5. The position of the shaft 14 with respect to the outer casing 10 is the same side (lower side) as the position -115-201103484 with respect to the axis 31 of the outer casing 10, so the front cover 1 is removed from the dust receiving portion 5. When 1 is opened, there is no possibility that the front cover 11 is obstructed, and a part of the dust box 12 can be ejected from the dust containing portion 5. Further, the shaft I4 may be provided with a coil spring that exerts an elastic force in a direction in which the dust box 12 is pushed toward the front cover 1 1 side. Thereby, when the front cover 1 is opened from the dust accommodating portion 5, a part of the dust box 1 2 can be strongly ejected from the dust accommodating portion 5 by the elastic force of the spring, and the user can easily discharge the accumulated dust collecting case. The dust inside 12. Further, the dust box 12' is divided into upper and lower sides, that is, the so-called two structures of the frame (bracket) of the upper half and the frame (bracket) of the lower half are preferably formed. The stacking box 12, which is divided into two, is joined together by a shaft 13 formed on the outer side of the bottom surface of the dust collecting case 12. Therefore, as shown in Fig. 4(A), the dust collecting box 12 has a fulcrum at the center of the bottom surface, and the opening surface of the dust box 12 is divided into upper and lower sides. In particular, when a part of the dust box 12 is ejected from the dust accommodating portion 5, the dust box 12 is divided into upper and lower sides. Thereby, the user can more easily discharge the dust accumulated in the dust collecting case 12, particularly the dust adhering to the inner surface of the dust collecting case 12, and can be easily scraped off. However, the dust box 12 is divided into two upper and lower parts, and is not essential. Further, as described above, since the front side of the outer casing 1 is inclined by 40 to 45 degrees with respect to the direction of gravity, the dust box 12 is ejected from the dust accommodation portion 5 by 30°, so that accumulation can be performed. The dust in the dust box 12 is discharged in a direction of substantially gravity. In the front cover 1 1 , an outer side flow path 35 and an inner side flow path 36 are formed in the axial direction. Further, the outer flow path 35' is formed on the upper side of the front cover 1', and the one end of the outer flow path 35 is communicated with the dust separation portion 4, particularly between the outer tube 6 and the inner tube 7. The opening of the extension portion 34, the other end of the outer flow path 35-116-8201103484 is an opening that communicates with the outer casing 10, particularly the dust box 12. When the electric vacuum cleaner is stopped, in order to prevent the dust accumulated in the dust collecting case 12 from flowing back to the outer flow path 35 and the dust separating unit 4, the other end of the outer flow path 35 is communicated with the opening of the dust collecting case 1 2 . Half of the upper side or upper end is better. However, the other end of the outer flow path 35 may communicate with the central portion of the opening of the dust box 12. Further, when the electric vacuum cleaner is stopped, in order to prevent the dust accumulated in the dust collecting case 12 from flowing back to the outer flow path 35 and the dust separating unit 4, the inside of the outer flow path 35 or the other end portion is formed to cover. The check valve (not shown) of the outer flow path 35 is preferred. The check valve is rotated toward the dust box 12 by the upper end being a fulcrum. However, check valves are not a mandatory component. The sectional area of the outer flow path 35 is enlarged from one end of the outer flow path 35 toward the other end. The direction in which the outer side flow path 35 is formed is from the one end of the outer side flow path 35 toward the other end and from the outer side of the front cover 11 toward the center side. That is, it is the direction from the outer side of the dust box 1 2 toward the center side. In order to suppress the disturbance of the air flowing in from the outer flow path 35 toward the dust collecting case 12, the direction in which the outer flow path 35 is formed is the wall surface (upper side wall surface) on the side where the outer flow path 35 of the stacking box 12 communicates. good. The inner flow path 36 is formed from the center to the lower side of the front cover 1 1 , and one end of the inner flow path 36 is open to the other end of the inner portion 7 of the inner portion 7 of the dust separation portion 4 (the inner tube 7) The other end of the inner flow path 36 is connected to the outer side of the outer casing, in particular, the dust collecting case 12. The other end of the inner flow path 36 is preferably connected to the outer lower side of the dust collecting case 12. The inner flow path 3 6 is formed to avoid the outer flow path 35. The cross-sectional area of the inner flow path 36 is opposite to the outer flow path 35, and is reduced from one end of the inner flow path 36 toward the other end. On the outer side of the upper portion of the dust accommodation portion 5, a handle 16 that can be held by a user extending in the horizontal direction -117-201103484 is provided. The user holds the handle 16 and lifts the dust accommodation portion 5 upward, while leaving the dust separation portion 4 in the cleaner body 1, and can remove only the dust accommodation portion 5 from the cleaner body 1. When the dust separating portion 4 and the dust accommodating portion 5 are connected to each other, the user can lift the dust accommodating portion 5 upward by holding the handle 16, and the dust separating portion 4 and the dust accommodating portion can be integrated. 5. That is, the dust collecting device 2 is also unloaded from the cleaner body 1. As shown in Fig. 1, the direction in which the other end surface of the dust receiving portion 5 in the axial direction (corresponding to the portion of the filter 15) is inclined more toward the outer casing 10 side than the vertical surface (gravity action direction). That is, it is preferable that the lower portion is closer to the outer casing 10 side than the upper portion of the other end surface in the axial direction of the dust containing portion 5. Further, as shown in Fig. 1, the direction of formation of the one end surface (corresponding to the portion of the front cover 11) in the axial direction of the dust accommodating portion 5 is inclined by 4 〇 toward the outer casing 10 side than the vertical surface (gravity action direction). ~45° or so. In other words, the lower portion of the upper end portion of the dust-receiving portion 5 in the axial direction is closer to the outer casing 10 side. Thereby, the one end surface in the axial direction and the other end surface in the axial direction of the dust accommodation portion 5 are inverted eight-shape based on the vertical surface (the direction of gravity action). Thereby, the user does not get stuck when the dust accommodating portion 5 is lifted upward, and the user can easily remove the dust accommodating portion 5 from the cleaner body 1. On the other hand, the user can remove the dust separating unit 4 from the cleaner body 1 by holding the dust receiving portion 5 and holding the recessed portion 3, the upper portion of the dust separating portion 4 or the upper side of the dust separating portion. As shown in Fig. 1, the direction in which the one end surface (corresponding to the portion of the inlet pipe 3) in the axial direction of the dust separating portion 4 is inclined more toward the outer tube 6 side in the vertical direction (gravity action direction). In other words, it is preferable that the lower portion is closer to the outer tube 6 side than the upper portion of the other end surface in the direction of the axis -118 to 201103484 of the dust separating portion 4. Thereby, the user does not get stuck when the dust separating portion 4 is lifted upward or obliquely upward, and the user can easily remove the dust separating portion 4 from the cleaner body 1. In addition, when the user separates the dust separating unit 4 from the dust collecting unit 4, the dust separating unit 4 and the dust containing unit 5 are integrated, that is, when the dust collecting device 2 is unloaded from the cleaner body 1, The one end surface of the dust device 2 in the axial direction and the other end surface in the axial direction are inverted eight-shaped on the basis of the vertical surface (gravity action direction), so that the dust collecting device 2 is not lifted when it is lifted upward, and the user can easily The dust collecting device 2 is unloaded from the cleaner body 1. At the body suction port 21, a hose joint pipe 20 is inserted to hold the hose joint pipe 20. A spacer 22 is provided at one end of the body suction port 21. Thereby, the airtightness of the hose joint pipe 20 and the inlet pipe 3 can be maintained. The front lower end of the cleaner body 1 (the lower side of the dust collecting device 2) is provided with a caster support portion 23 for supporting the casters. An intake duct 27 that extends toward the front-rear direction of the cleaner body 1 is provided on the upper rear side of the cleaner body 1. The opening of one end of the suction duct 27 in the extending direction is opposed to the filter 15. An auxiliary filter 26 is provided in the vicinity of the opening of one end of the intake duct 27. Thereby, it is possible to suppress the electric blower 28 from sucking the dust remaining outside the dust collecting device 2. The other end of the suction duct 27 in the extending direction is closed, and the lower portion near the other end of the intake duct 27 in the extending direction, that is, the side of the electric blower 28 is opened as the discharge port 27b of the intake duct 27. An upper portion of the opening of the suction duct 27 of the cleaner body 1 is provided with a dust removing device 24 for removing dust adhering to the filter 15 at a position in contact with the filter 15. Dust removal -119- 201103484 The device 24 is provided with a spiral spring (elastomer) on the outer circumference of the rotor. The dust removing device 24 is rotated by the pulling out of the motor or the wire reel, and the dust adhering to the filter 15 is shaken off by the filter member 79 of the spiral spring bounce filter 15. As described above, since the direction of the fold of the filter 15 is the longitudinal direction, the dust that has been shaken off tends to fall toward the direction of gravity. The dust that has been shaken off from the filter 15 is accumulated in the casing 10. Thereby, the mesh clogging of the filter 15 can be suppressed, the pressure loss of the air can be suppressed from being lowered, and the decrease in the suction force can be suppressed. As shown in Figs. 1 and 43 , an electric blower 28 that generates an attraction force is provided on the lower rear side of the cleaner body 1. The electric blower 28 is placed upright so that the suction port of the electric blower 28 faces upward. The electric blower 28 is the longest from the surface of the suction port 28a to the opposite surface of the surface of the suction port 28a. Therefore, by setting the suction port 28a of the electric blower 28 upward, the electric blower 28 is placed in a vertical manner, whereby the length of the cleaner body 1 from the hose joint pipe 20 to the main body exhaust port 30 can be shortened. In the cleaner body 1, an intake duct 27 is provided at the upper portion of the electric blower 28, and the suction port 28a of the electric blower 28 is connected to the discharge D27B of the intake duct 27. In the present embodiment, the electric blower 28 is installed in the cleaner body 1 so that the upper portion of the electric blower 28 is provided with the suction port 28a, and the side of the electric blower 28 is provided with the exhaust port 28b. Settings. The cleaner body 1 is provided on the downstream side of the electric blower 28 and on the front side of the electric blower 28, and is provided with an exhaust duct 40 that communicates with an exhaust port of the electric blower 28. Further, on the downstream side of the exhaust duct 40 and on the front side of the exhaust duct 40, a filter 29 communicating with the duct 40 of the exhaust gas - 120 - 201103484 is provided. The exhaust duct 40 and the filter 29 are fixed by means of fixing means such as screws. This is to keep the exhaust duct 40 and the filter 29 airtight by fixing the exhaust duct 40 and the filter 29, so that all the exhaust gas discharged from the electric blower 28 passes through the filter 29, and borrows The exhaust gas discharged from the electric blower 28 can be filtered by the filter 29. The filter 29 is formed in a frame having a substantially quadrangular cross-sectional shape, and is formed with a filter member folded into a pleat shape. The direction of the waviness of the filter member is preferably in the longitudinal direction (the direction of gravity action). The filter 2 9, for example, is a high density ULPA filter (Ultra Low Penetration Air Filter). ULPA filter 'for a rated air volume and a particle size of 0. 15 // m particles, with 99. The particle collection rate of 9995% or more is an air filter having an initial pressure loss of 24 5 Pa or less, and has a particle collection efficiency higher than that of the HEP A filter. Further, a rear exhaust port 30 is provided at the rear end surface of the cleaner body 1. As shown in Fig. 44, the electric wire 47 is provided with a plug 43 at the front end. Electric power is obtained by inserting the plug 43 into a socket located in a house or the like. When an electric vacuum cleaner other than the vacuum cleaner is used, the electric blower 28 or the like cannot be operated unless the plug 43 is inserted into the socket. Therefore, it is preferable that the electric vacuum cleaner is provided with the wire reel 4 1 in a place where it does not hinder the operation. Hereinafter, the place where the wire reel is set is referred to as a wire reel chamber 42. If the wire reel chamber 42 is provided at the front portion of the cleaner body 1 in such a manner that the plug 43 or the electric wire 47 can be pulled out from the front portion of the cleaner body 1, the plug 43 or the electric wire 47 is pulled toward the traveling direction. Out, so it is not easy to operate when cleaning and cleaning. If the plug 43 or the electric wire 47 can be pulled out from the side surface portion or the upper surface portion of the cleaner body -121 - 201103484 1 , the wire reel chamber 4 2 is provided on the side surface portion or the upper surface portion of the cleaner body 1 In the case of the case, it is also difficult to operate when cleaning and cleaning. Therefore, the wire reel chamber 42 is disposed in the rear portion of the cleaner body 1 in such a manner that the plug 4 3 or the electric wire 47 can be pulled out from the rear end surface of the cleaner body 1, thereby not becoming a traveling direction or a direction change. Obstructed on, and easy to operate. In the present embodiment, the electric blower 28 and the electric wire reel chamber 42 are disposed adjacent to each other in the cleaner body 1. Further, the electric blower 28 and the electric wire reel chamber 42 are disposed in the cleaner body 1 at a rear portion of the dust collecting device 2. As shown in Fig. 54, in the present embodiment, the length of the electric wire reel chamber 42 in the longitudinal direction is longer than the length of the electric blower 28 in the longitudinal direction, but is added after the electric blower 28 and the exhaust duct 40 are added. The length in the longitudinal direction is also shorter. The filter 29 is located in the cleaner body 1 at a substantially central portion in the longitudinal direction of the cleaner body 1. Further, as can be seen from Fig. 1 or Fig. 43, in the cleaner body 1, the filter 29 is positioned below the filter 15. When the cleaner body 1 is placed horizontally, if the angle parallel to the lower surface of the cleaner body 1 is 0°, the dust collecting device 2 is inclined as long as the axis of the dust collecting device 2 is inclined relative to the lower surface of the cleaner body 1 by 0°. The side view will be a right-angled triangle with the axis of the dust collecting device 2 as a hypotenuse. The length in the height direction of the right-angled triangle in the side view of the dust collecting device 2 is longer than the length in the height direction of the filter 15, and the length in the height direction of the dust collecting device 2 and the height direction of the filter 15. The length will vary. When the filter 15 is placed in the dust collecting device 2 such that the difference is formed below the filter 15, a space is formed in the lower portion of the filter 15 from -122 to 201103484. The filter 15 is located at a substantially central portion in the longitudinal direction of the cleaner body 1 and is a substantially central portion in the width direction, and is also wide in width. Therefore, in the cleaner body 1, the wire reel chamber 42 cannot be placed in the filter. Next to the device 15. Further, since the length from the lower surface of the cleaner body 1 to the filter 15 is shorter than the length in the height direction of the wire reel chamber 42, the wire reel chamber 42 cannot be provided below the filter 15. By the above, the filter 29 is placed in the space created by the filter 15, and the area of the filter 29 can be increased. The shaft of the dust collecting device 2 is described as being inclined with respect to the lower surface of the cleaner body 1. However, if the shaft is not inclined, as shown in Fig. 53, a space cannot be formed below the filter 15. Further, even if the shaft of the dust collecting device 2 is perpendicular to the lower surface of the cleaner body 1, a space is formed below the filter 15, and the area of the filter 29 can be increased. As shown in Figs. 1 and 43, the exhaust duct 40 is provided between the electric blower 28 and the filter 29. The exhaust duct 40 is a hollow member which is covered by a side portion of the electric blower 28 covering a lower outer peripheral portion 44 (in the 42nd to the lower right diagonal line portion), and an exhaust port from the electric blower 28. The tubular shape passage portion 48 between the periphery of the 2b and the filter 29 is connected to the filter. The outer peripheral portion 44 has a substantially angular column shape and a diameter of about half of the width of the rear portion of the cleaner body 1, and the length in the height direction is shorter than the length in the height direction of the electric blower 28, and the upper surface of the outer peripheral portion 44 is provided. The opening 44a is provided with an opening 44b on the side surface of the outer peripheral portion 44. A gasket 19 such as rubber is provided between the upper surface of the outer peripheral portion 44 and the electric blower 28, and the air blower-123-201103484 between the exhaust duct 40 and the electric blower 28 is obtained, and the electric blower 28 is suppressed. The effect of vibration when using. The opening portion 44b on the side surface of the outer peripheral portion 44 faces the exhaust port 28b of the electric blower 28. The size of the opening portion 44a on the upper surface of the outer peripheral portion 44 is larger than the diameter of the electric blower 28, and the outer peripheral portion side opening portion 44b is smaller than the diameter of the electric blower 28. Further, as shown in Fig. 42, the passage portion 48 is composed of two portions of a cylindrical shape. One of them is an inclined portion with respect to the other side of one side (hereinafter referred to as a passage portion A45, which is a portion which is a horizontal line in Fig. 42), and the other one is substantially parallel to one side and the other side. The portion (hereinafter referred to as the passage portion B46 is a diagonally scribed portion toward the upper right in Fig. 42). Both the passage portion A45 and the passage portion B46 have an inlet as an opening portion. The inlet of the passage portion A4 5 (hereinafter referred to as the inlet A45a) is connected to the outer peripheral side opening portion, and the outlet of the passage portion A45 (hereinafter referred to as the outlet A45b) is connected to the inlet of the passage portion B46 (hereinafter referred to as the inlet B45a). The outlet of the passage portion B46 (hereinafter referred to as the outlet B45b) is coupled to the filter 29. The inlet A45a is smaller than the outlet A45b, and the inlet B46a is substantially the same size as the outlet B46b. The inlet A45a is formed to have the same size as the outer peripheral side opening portion 44b, and the outlet A45b and the inlet B46a are set to have the same size. Further, the length from the inlet A45a to the outlet A4 5B is longer than the length from the inlet B46a to the outlet 46B. This is to prevent the entire length of the cleaner body 1 from becoming long. Further, the outlet B46b connected to the filter 29 in the passage portion 48 of the exhaust duct 40 is wider than the inlet A45 5a connected to the outer peripheral portion 44. Further, the height from the entrance A45a to the outlet B46B of the passage portion 48 is unchanged. The upper surface of the passage portion 48 is parallel to the lower surface. In the cleaner body 1, 'from -124 to 201103484 is disposed beside the wire reel chamber 42 from the outer peripheral portion 44 to the passage portion A45, and the passage portion B46 and the filter 29 are disposed in front of the electric wire reel chamber 42. Therefore, if the length from the inlet B46a to the outlet B46B is increased, the total length of the cleaner body 1 also increases the amount of increase. The exhaust duct 40 has a passage that communicates from the opening portion 44a to the outlet portion B45b. The exhaust duct 48 means a larger passage through which the inside of the exhaust duct 48 is communicated. When the cleaner body 1 is placed laterally, the view (front view) when the passage portion A45 is viewed from the side of the cleaner body 1 and the view (side view) when viewed from the rear of the cleaner body 1 are both rectangular, and the vacuum cleaner The figure (plan view) when viewed from above the body 1 is trapezoidal. The front view, the side view, and the plan view of the passage portion B 46 are all rectangular. The outer peripheral portion 44 of the exhaust duct 40 is coupled to the passage portion A45, and the passage portion A45 is coupled to the passage portion B46. The respective links are connected in a smooth manner. This is carried out to prevent turbulence or useless use of the exhaust gas flow in the respective connecting portions. In the passage portion A45, the other side surface is formed to be inclined by about 40 to 50 degrees with respect to one of the side faces. This has the effect that: (the passage portion) is enlarged to enable the size of the filter 209 to be matched, in addition to the effect of slowing the flow rate, and the passage portion is enlarged to avoid being disposed beside the electric blower 28. The effect of the wire reel chamber 42. In the present embodiment, the plan view of the electric wire reel chamber 42 is rectangular. The long side of the wire reel chamber 42 is substantially parallel to one side of the side of the passage member A45 that is separated from the wire reel chamber 42. The side of the passage member A45 close to the side of the electric wire reel chamber 42 is inclined from the inlet A45a to the outlet A45b so as to be close to the electric wire reel chamber 42. The passage portion -125- 201103484 B46 has a wide width from the front of the electric blower 28 to the wire reel chamber 42. There is a reason why the outer peripheral portion 44 and the passage portion B46 are directly connected to each other and the passage portion A45 as the inclined portion is connected to the middle. If the inclined portion is not provided and the outer peripheral portion 44 and the passage portion B 4 6 are joined, the wide width is abruptly expanded from the wide width of the outer peripheral portion 44 to the wide portion of the passage portion B46. In this case, the exhaust gas discharged from the exhaust port 28b of the electric blower cannot reach the wide expanded portion, which reduces the effect of increasing the effect of the filter 29. In order to avoid such a deficiency, a structure in which the wide and wide expansion is provided is preferably provided so that the exhaust gas can be easily reached to the wide expanded portion of the filter 29. In order to gradually make the wide width into the expanded structure and thus the passage portion A45, the effect produced by providing this configuration is as described above. In the present embodiment, the size of the outlet A45b is smaller than the size of the outlet B46b, but is not limited thereto. The size of the outlet A45b may be made the same size as the size of the outlet B46b, and the width of the outlet A45b may be gradually expanded from the outer peripheral portion 44 to the filter 29 (from the entrance nA45a to the outlet B46B). In the present embodiment, the front view, the side view, and the plan view of the passage portion A or the passage portion B are limited to a rectangular shape or a trapezoidal shape, but are not limited thereto. In addition to this, as long as the passage portion 40 is formed to have a flared structure, there is no problem in the front view, the side view, and the plan view even if it is circular or square. In order to keep the exhaust of the vacuum cleaner quiet, it is necessary to improve the dust-removing performance of the vacuum cleaner. For this reason, it is only necessary to use a filter having a high particle trapping rate like a ULP A filter. However, if the particle capture rate of the filter is high, the density of the filter is higher, that is, the pressure loss is higher, and the result is an increase in the possibility of blockage. In order to reduce the pressure loss, it is necessary to increase the surface area of the filter. The pleats of the filter 29 are used to increase the surface area. However, if you want to further reduce the pressure loss, you must increase the filter itself. It is possible to simply provide a large filter in the vacuum cleaner, but it is necessary to prevent the vacuum cleaner body from becoming large. Providing a large filter at the rear of the cleaner body without increasing the body of the cleaner will make the wire reel 4 1 provided at the rear of the cleaner body an obstacle. Therefore, it is preferable that a large filter is provided in the central portion of the cleaner body without the wire reel 41. Having said that, if the filter is placed in the center, the body will become longer. In this embodiment, as shown in Fig. 1, the dust. The separation unit 4 and the dust collecting unit 5 are disposed on the cleaner body 1 at an inclination of about 40 to 45 with respect to the floor surface when the cleaner body 1 is placed horizontally. This is because the dust separating portion 4 is separated from the dust collecting portion 5 to prevent the height direction of the cleaner body from being excessively large, thereby forming a space between the dust separating portion 4 and the lower portion of the dust collecting portion 5. The filter 29 is provided in this space, and the vacuum blower body 1 is prevented from becoming long by erecting the electric blower 28. Further, since the width of the ULP A filter is wider than that of the electric blower 28, the width of the exhaust duct 40 connecting the electric blower 28 and the ULP A filter becomes the same as from the electric blower 28 toward the filter 29. A structure that shifts and widens. Since the width of the exhaust duct 40 is widened as it travels from the electric blower 28 toward the filter 29, the flow velocity is gradually weakened, and the dust is easily collected by the filter 29. Further, in order to allow all of the exhaust gas from the electric blower 28 passing through the exhaust duct 40 to pass through the filter 29, the electric-127-201103484 blower 28 and the exhaust duct 4A and the filter 29 are sealed, so that all The exhaust gas can pass through the filter 29, and can achieve high dust-removing performance and clean exhaust. Next, the flow of air during operation (when used) of the electric vacuum cleaner will be described. The arrow in Fig. 1 shows the air flow direction. When the user turns on the power of the electric vacuum cleaner, the electric blower 28 operates to generate an attractive force. The air taken in from the hose joint pipe 20 flows into the outer cylinder 6 through the inlet pipe 3, and collides with the recessed portion 8 to be redirected in the radial direction, and further, the outer peripheral end of the inner cylinder 7 in the recessed portion 8 The position is slightly changed to the circumferential direction, and then redirected toward the circumferential direction at the guide tube 38. As a result, the air is swirled around the outer cylinder 6 around the axis of the outer cylinder 6. That is, it becomes a swirling flow. With the centrifugal separation caused by the swirling of the air, the heavier dust contained in the air concentrates on the outside of the swirling flow. The lighter dust contained in the air is not only on the outside of the swirling flow but also on the inside. However, in general household cleaning, most of the dust is concentrated on the outside of the swirling flow, and there is less dust remaining on the inner side of the swirling flow. The air outside the inner cylinder 7 passes through the outer flow path 35 together with the heavy dust, and flows into the dust box 12. The dust is trapped by the dust box 12 and accumulated, and then compressed by the attraction. Since the dust is automatically compressed by the attraction, it is possible to maintain a lot of dust without bothering the user's hand. The air reaches the filter 15 through the bottom surface of the dust box 12 and the upper, lower, left and right surfaces. On the other hand, the inside air ' of the swirling flow flows into the inner cylinder 7 from the through hole 33 of the inner cylinder 7. The dust larger than the through hole 33 cannot pass through the through hole 33 and remains outside the inner cylinder 7. The air in the inner cylinder 7 flows into the outer side of the dust collecting box 1 2 8 -128- 201103484 through the inner flow path 3 6 ' through the inner flow path 3 6 ' together with the lighter dust of the dusty dust. Device 15. The air in the dust box 12 and the air that has not passed through the dust box 12 are merged in front of the filter 15 and passed through the filter 15. In the filter 15, it is to collect lighter dust and dust contained in the dust and other air. The air that has passed through the filter 15 and is almost free of dust is passed through the auxiliary filter and flows into the intake duct 27, and is sucked from the suction port of the upper portion of the electric blower 28 through the opening of the lower portion of the intake duct 27. The air discharged from the discharge port on the side of the electric blower 28 passes through the exhaust duct 40 widened toward the filter 29 to reach the filter 29, and is trapped in the filter 15 by the filter 29. Unable to capture clean dust. The air passing through the filter 29 passes through the periphery of the electric blower 28 or the electric wire reel chamber (not shown), the gap between the lower portion of the cleaner body 1, and the like, and is then discharged from the main body exhaust port 30 toward the outside of the cleaner body 1. In particular, since the filter 29 has the dust collecting efficiency of the same degree or more as that of the filter used for the air cleaner, the air discharged from the cleaner body 1 toward the outside is purified to be the same as the air cleaner. Degree or more. A substrate 49 is provided at a lower portion of the exhaust duct 40. Since the substrate 49 is an important part of the electrical operation of the electric vacuum cleaner, such as the operation of the electric blower 28, there is a fear that the dust may adhere to the substrate 49. Basically, it is covered with a cover or the like in order not to cause an adverse effect. However, since the cleaned air passing through the filter 29 passes through the substrate 49 in the present embodiment, the adverse consequences are further reduced. Fig. 2(A) is a perspective view showing a dust collecting device of the embodiment of the present invention - 129 - 201103484, and Fig. 2 (B) is a transverse sectional view showing the dust collecting device of the embodiment of the present invention. . The user can lift the dust collecting device 2 from the cleaner body 1 by holding the handle 16 and lifting the dust collecting device 2 upward. However, the dust separating portion 4 may be left in the cleaner body 1, and only the dust containing portion 5 may be removed from the duster body 1. As shown in Fig. 2(A), the outer shape of the cross section of the dust separating portion 4 as viewed from the axial direction is substantially circular. The outline of the cross section of the dust accommodating portion 5 has a substantially circular shape in the portion of the front cover 11, and the portion of the front cover 11 has a substantially square shape in the future, and the portion of the filter 15 has a substantially square shape. As shown in Fig. 2(B), the opening direction of one end of the outer casing 10 in the axial direction is not in a straight line with the opening direction of the other end of the outer casing 1 轴, but has a difference of about 45 to 50 degrees. That is, the axial direction of the dust accommodating portion 5 is curved somewhat closer to the front side than in the middle. As described above, the one end surface of the dust collecting device 2 (the portion of the inlet pipe 3) is slightly downward (the direction of gravity action), and the other end surface of the dust collecting device 2 (the portion of the filter 15) is also In the downward direction (gravity action direction), the one end surface of the dust collecting device 2 and the other end surface in the axial direction are based on the vertical surface (gravity action direction), and the dust is collected in the inverted figure shape. When the device 2 is lifted upward, it is relatively unhooked, so the user can easily remove the dust collecting device 2 from the cleaner body 1. Fig. 3(A) is a perspective view showing an inner cylinder and an outer cylinder according to an embodiment of the present invention, and Fig. 3(B) is a perspective view showing the inner side of the inner cylinder according to the embodiment of the present invention. The one end surface ' of the outer cylinder 6 is closed except for the portion forming the inlet pipe 3; the other end surface of the outer cylinder 6 is open. The inner cylinder 7' has an annular extension portion 34 at one end of the cylindrical portion of 8 - 130 - 201103484. As shown in Fig. 3(A), the outer peripheral end of the other end surface of the outer cylinder 6 abuts against the outer peripheral end of the extension portion 34 by being inserted into the outer cylinder 6 from the cylindrical portion of the inner cylinder 7 toward the axial direction. The inner cylinder 7 is formed in the outer cylinder 6. As shown in Fig. 3(A), the opening direction of the inlet pipe 3 is opposite to the opening of the recessed portion 8. The opening direction of the outer peripheral end portion of the inner tube 7 toward the recessed portion 8 is substantially downward, and the opening direction of the guide tube 38 in the circumferential direction is reversed clockwise. Further, the direction of the opening of the guide tube 38 in the circumferential direction can also be rotated clockwise. Further, the upper portion of the extension portion 34 has a hole penetrating in the axial direction, that is, the upper portion of the extension portion 34 is an opening. The left wall of the opening is higher than the right wall. That is, the wall surface (left wall surface) of the opening of the upper portion of the extension portion 34 facing the opening direction of the guide duct 38 is higher than the other wall surfaces (right wall surface). Further, the surface of the extension portion 34 has a spiral shape and has a flow path function of guiding the air smoothly to the opening of the upper portion of the extension portion 34. As shown in Fig. 3(B), the semicircular portion on the upper side in the inner cylinder 7 is provided with a recessed portion 3 9 which is recessed toward the inner side of the inner cylinder 7, and a substantially semicircular portion on the lower side, which faces the inner cylinder 7. Opened □. In the dust collecting case 12, when the flow rate of the air outside the inner cylinder 7 is larger than the flow rate of the air in the inner cylinder 7 in the state where no dust is accumulated, the opening area in the inner cylinder 7 may be larger than the opening area in the inner cylinder 7. The opening area of the upper portion of the extension portion 34. The area in which the recessed portion 39 is formed may be larger than the opening in the inner cylinder 7, and the area toward the opening in the inner cylinder 7 may be made larger than the recessed portion 39'. On the other hand, the user can easily hold the dust separating portion 4 or the inner tube 7 by placing the finger in the recess portion 39. The cylindrical portion of the inner cylinder 7 is formed of a metal material having an antibacterial effect -131 - 201103484. In the case, first, it is a thin metal plate having a diameter of 0. 1 mm~0. A plurality of through holes 3 3 of about 4 mm are etched, and then both ends are joined into a cylindrical shape. The through hole 3 3 can also be punched. As the metal material for the antibacterial effect, for example, there are stainless steel, silver, copper, and the like. It is not limited to stainless steel, silver, or copper, and may be any alloy containing silver or copper or silver or copper deposited on the surface. The thickness of the metal thin plate is 1 mm or less, and in order to improve the workability, the thickness is 0. 1mm~0. About 5mm is better. When the thickness of the thin metal plate is thin, in order to increase the strength or the roundness, both ends of the cylindrical metal thin plate in the axial direction are preferably fixed by a resin having good moldability. Specifically, the shape formed by one end portion of the substantially circular inner tube 7 having the recessed portion 8 or the guide tube 38 and the shape of the other end portion of the inner tube 7 having the annular extension portion 34 are formed. A cylindrical metal sheet is set to be 'subsequent' by insert molding into the mold by pouring resin into the mold. It is also not necessary to join both ends of the metal sheet to form a cylindrical shape by the case of insert molding. Thus, the substantially circular one end portion including the inner tube 7 having the recessed portion 8 or the guide tube 38 and the other end portion of the inner tube 7 including the annular outer portion 34 may be made of resin and only the inner tube 7 The cylindrical portion is made of a metal material. The manufacturing process can be simplified by insert molding. Fig. 4(A) is a perspective view showing a state in which the front cover 11 of the dust accommodating portion 5 of the embodiment of the present invention is opened, and Fig. 4(B)' is a dust accommodating the embodiment of the present invention. A perspective view of the state in which the rear filter of the portion 5 is opened. When the front cover 转动 is rotated in the lower direction with the shaft 31 as a fulcrum as shown in Fig. 4(A), the dust box 12 is also rotated and ejected in the lower direction with the shaft 1 4 as a fulcrum. At this time, the dust box 1 2 ' is cut into upper and lower sides by the axis 13 as a fulcrum. The opening of the dust collecting case 12 when ejected from the dust containing portion 5 is expanded in comparison with the opening of the dust collecting case 12 when it is housed in the dust containing portion 5. Thereby, the dust adhering to the inner surface of the dust box 1 2 can be easily scraped off. When the user wears the fiber paper along the inner surface of the dust box 12, the end portion of the fiber paper is sandwiched between the frame of the opening of the dust box 1 2 and the outer peripheral end of the front cover 1 1 . It can inhibit the fiber paper from shifting or falling off. As shown in Fig. 4(B), the filter 15 is rotated and opened in the lower direction with the shaft 3 2 as a fulcrum. Thereby, the user can easily discharge the dust accumulated outside the dust collecting case 12 in the outer casing 10, and further, the dust adhering to the side surface of the outer casing 10 of the filter 15 can be easily removed. Fig. 5(A) is a front view of the front cover of the dust containing portion 5 of the embodiment of the present invention as seen from the outside of the dust containing portion, and Fig. 5(B) is a view of the present invention viewed from the inside of the dust containing portion. A front view of the front cover of the dust receiving portion 5 of the example. Further, the hatched portion in the figure is not a cross section, and the front surface is displayed. The lower end of the front cover 11 is provided with a shaft 31 that is rotatably supported by the outer casing 10. The front cover is generally circular. The substantially circular portion on the outer side of the hatched portion shown in Fig. 5(A) is an outer peripheral end that can abut against the other end surface of the dust separating portion 4 in the axial direction. The substantially circular portion inside the hatched portion shown in Fig. 5(A) is an outer peripheral end that can abut against the other end surface of the inner cylinder 7 of the dust separating portion 4 in the axial direction. On the upper side of the front cover 11 which is opposite to the shaft 31, an opening of the outer flow path 35 is formed between the substantially circular portion on the outer side of the oblique portion and the substantially circular portion on the inner side. The opening position of the front side of the outer flow path 35 (outside the dust accommodation portion 5) may be on the left and right sides or the lower side of the front cover 1 1 , but on the back side of the outer flow path 3 5 (the dust accommodation portion 5) When the opening position of the inner side is made on the upper side of -133-201103484 of the front cover 1 1 , in order to shorten the length of the outer flow path 35 to reduce the pressure loss of the air, the opening position on the surface side of the outer flow path 35 is also The upper side of the front cover 11 is preferred. On the other hand, an opening of the inner flow path 36 is formed inside the inner cylinder 7. In the front view of Fig. 5(A), the opening area of the inner channel 36 is larger than the opening area of the outer channel 35, but the upper semicircular portion 'in the inner tube 7 is formed with the recess 39'. Therefore, when the flow rate of the air outside the inner cylinder 7 is larger than the flow rate of the air in the inner cylinder 7, the opening area of the inner flow passage 36 is larger than the opening area of the outer flow passage 35 as the substantial flow passage area. small. Further, the substantially circular portion on the outer side of the oblique line portion and the open portion apos formed in the substantially circular portion on the inner side without forming the outer flow path 35 are closed. The substantially circular portion 'outer side of the hatched portion shown in Fig. 5(B) is a part of the outer peripheral end of the one end surface in the axial direction of the outer casing 1A and the outer peripheral end of the opening of the dust collecting case 12. As shown in Fig. 5(B), an opening of the outer flow path 35 is formed on the side of the center line of the front cover 11 in the up-and-down direction. Therefore, when the electric vacuum cleaner is stopped, the dust accumulated in the dust collecting case 12 can be prevented from flowing back toward the outer flow path 35 and the dust separating unit 4. However, the opening of the outer flow path 35 may be formed in the central portion of the center line of the upper and lower sides of the front cover 1 1 . Further, it is preferable to form a check valve (not shown) that covers the outer flow path 35. Thereby, even when the electric vacuum cleaner is stopped, the dust accumulated in the dust collecting case 12 can be prevented from flowing back toward the outer flow path 35 and the dust separating portion 4. On the other hand, an opening of the inner flow path 36 is formed in the vicinity of the lower end of the front cover 11. However, the opening position of the inner side flow path 36 may be the lower side or the left side or the upper side with respect to the opening position of the outer side flow path 35.
