201200092 六、發明說明： 【發明所屬之技術領域】 本發明係有關電動吸塵器’特別是關於旋風式之電動 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，在塵埃容納室內除老質量較 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動吸塵器。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 之電動吸塵器。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，網目狀的網狀過濾器及 褶狀的過濾器係以下端爲軸來轉動打開。 於專利文獻3，記載有一於集塵殻體內部設置用以捕 -5- 201200092 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動吸塵器。 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動吸 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- 201200092 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 個殼體予以組合，而形成迴旋流路、並連流路以及集塵空 間之電動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 內殼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容納於 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 201200092 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動吸塵器 。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，過濾器殻體也相對於地板面，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容納室，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，集塵裝置容納室爲隨著越上方變得越寬地形 成，而於集塵裝置之容納時，引導集塵裝置能被圓滑地容 納的電動吸塵器。 〔先前技術文獻〕 〔專利文獻〕 〔專利文獻1〕日本特開2 003 - 1 9005 6號公報 〔專利文獻2〕日本特開2007-000383號公報

與該空氣一同被從吸氣筒下側吸入，其結果，朝向電動送 風機前的第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，由於網目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目狀的網狀過濾器的塵埃 之虞。 在此，代替專利文獻2之網目狀的網狀過濾器，而考 慮設置了專利文獻3的塵埃容納器，不過專利文獻3的塵埃 -9 - 201200092 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麈外殼彈出 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 ，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殼的內側下表面，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摩會變得更長，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 -10- 201200092 有無法充分將污染空氣分離之虞。又，於I 於從迴轉力賦予手段到排出口的筒部之間很 迴轉力賦予手段到排出口的筒部之間多重迴 能量損失較大，又，亦有產生噪音之虞。又 4，由於迴轉力賦予手段爲由複數個翼（散 ’故空氣的能量損失較大，又，亦有產生噪 於專利文獻4，由於沒有設置從集塵箱朝向 ，從旋風機體排出的排氣僅爲相當於內筒之 ，故排氣空氣的能量損失較大。又，於專矛 沒有設置將蓄積於集塵箱的塵埃予以壓縮的 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 ，形成有使迴旋流產生的流路，故旋風集塵 (軸方向）的長度會變得較長，其結果，會 的前後方向的長度變長之虞。又，由於中 性網目過濾器之部分的形狀爲三角錐，故隨 方向（軸方向）的下游側接近（隨著從三角 底部接近），塵埃越易於附著於1次性網目 ，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 側，形成有緩衝空間及迴旋流路形成部，故 方向（上下左右方向）的長度會變得較長， 吸塵器本體的前部的高度及橫向寬幅變得較 於專利文獻7及專利文獻8 ’沒有記載旋 ί利文獻4 ,由 長’而空氣從 旋’故空氣的 ，於專利文獻 熱片）所形成 音之虞。又， 外部的排氣口 小徑的排氣口 J文獻4，由於 手段，故集塵 的前側之蓋內 器的水平方向 有吸塵器本體 ί之形成有1次 著越朝向水平 錐的頂部越朝 過濾器的表面 半徑方向的外 集塵室的半徑 其結果，會有 大之虞。 風分離筒及集 -11 - 201200092 塵外殻之間的密封機構，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殻的接合面大 幅傾斜之場合，在旋風分離筒與集塵外殻之間單僅使密封 構件介在其中，會有不能得到充分氣密之虞。 在此，本發明之目的，爲提供一種不必加大塵埃容納 部的容積，即可確保充分的集塵容量，且小巧之電動吸塵 器。 又或，本發明之目的，爲提供一種可減低迴旋於塵埃 容納部內的空氣之紊亂，並減低通過塵埃容納部之集塵盒 的網目過濾器的塵埃量，可抑制丟棄垃圾時之塵埃的飛散 之電動吸塵器。 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、或散落之電動吸 塵器。 〔解決問題之技術手段〕 本發明之特徵爲：使設置於第2集塵部（例如，塵埃 容納部）的蓋部（例如，前蓋）之第1流路（例如，外側

本發明之實施例1的電動吸塵器，爲具備有吸塵器本 體1及集塵裝置2;該吸塵器本體1爲具備有電動送風機28 ’該集塵裝置2爲可自由裝卸於吸塵器本體1，其特徵爲： 集塵裝置2，爲具備有使吸入之空氣迴旋而從空氣將塵埃 分離之分離部（例如：塵埃分離部4 )、以及連通於分離 部並容納塵埃之容納部（例如：塵埃容納部5)，分離部 與容納部，爲朝向軸方向排列，容納部，爲具備有過濾器 (例如：集塵盒12)，該過濾器爲具備有朝向與分離部連 通之側呈開口並朝向與連通於分離部之側爲相反側凹陷的 -14- 201200092 形狀，分離部的迴旋流之外側的空氣’爲流入容納部內的 過濾器內，分離部的迴旋流之內側的空氣，爲流入容納部 內且爲過濾器的外側。 而，根據本發明之實施例1，藉由將分離部及容納部 朝向軸方向排列並連通，然後，使分離部的迴旋流之外側 的空氣流入於容納部內之具備有凹陷形狀的過濾器內，使 分離部的迴旋流之內側的空氣流入於容納部內且具備有凹 陷形狀的過濾器的外側，則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 引力之降低。 又或，本發明之實施例1的電動吸塵器，爲具備有吸 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28的第2集塵部（例如：塵埃容納部5 )，第1集塵部， 是將於圓周面具備有複數個貫通孔33之內筒7內包於大致 圓筒狀內，第2集塵部，是將朝向與第1集塵部連通之側開 口且具備有朝向與第1集塵部連通之側爲相反側凹陷的形 狀之通氣構件（例如：集塵盒12)內包起來，第1集塵部 之內筒7的外側，爲連通於第2集塵部內之具備有凹陷形狀 的通氣構件的開口，第1集塵部之內筒7的內側，爲連通於 -15- 201200092 :在第2集塵部內且具備有凹陷形狀的通氣構件的外側。 而，根據本發明之實施例1 ’藉由將第2集塵部連通於 第1集塵部的軸方向端部，然後’將第1集塵部之內筒7的 外側連通於第2集塵部內之具備有凹陷形狀的通氣構件的 開口，將第1集塵部之內筒7的內側連通於：在第2集塵部 內且具備有凹陷形狀的通氣構件的外側’則不用煩勞使用 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，可抑制吸引力之降低。 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。於電動吸塵器之使用狀態，吸塵器本 體1爲橫放，於電動吸塵器之收納狀態，則以吸塵器本體1 爲立放較理想。於電動吸塵器之使用狀態，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，則於電動吸塵器之收納狀態，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1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。從吸入之空氣來捕 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 -16- 201200092 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40度〜45度左右。不過，要提高由離心分 離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，將塵埃容納部5配置於 上側者，亦可代替以將塵埃分離部4配置於上側，將麈埃 容納部5配置於下側。於該場合，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。 集塵裝置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，爲朝向集麈 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。而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 -17- 201200092 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1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的中空之大致圆筒 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 -18 - 201200092 的開口方向’亦可爲向上方向或橫向方向。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’會變成凹陷部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001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。藉此， 可持續抑制壓力損失而使空氣充分地迴旋。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3 4。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 -19 - 201200092 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，包含圓简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。而使 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內筒7內流入，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il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，於內筒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39。 凹陷部3 9爲具備有把手的功能。藉此，使用者將手指插入 -20- 201200092 凹陷部39，可手持塵埃分離部4或內筒7。外延部3 4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，而於圓周方向 之引導管3 8的開1=1便j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 一方面，內筒7的內側，爲連通於前蓋1 1的內側流路3 6。 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 大致倒三角形之中空的外殼10°外殼10的軸方向一端面’ 爲藉由可開閉之前蓋11被封閉。於前蓋11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爲支點而可朝向外殼1〇的軸方向前後旋動。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 -21 - 201200092 桿），於按鈕17，連結有朝向外殼10的前側延伸之傳達棒 (桿）1 8。傳達棒1 8的一端，爲連結於按鈕1 7，傳達棒1 8 的另一端，係形成爲卡爪。傳達棒的另一端的卡爪’爲 可卡合於前蓋11的上端部的卡爪。於外殼1〇閉合有前蓋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11打開。然後，若使用者按下 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U的上端部的卡爪 的卡合會被解除，可藉由重力從外殼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1 1部分）的法線方向，是相對於水平方向呈傾 斜45度〜50度。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，於後有述，集塵盒（集塵容器 )1 2，爲藉由彈簧（彈性體）以朝向外殻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I2的按壓力平順地從 外殼10將前蓋1 1打開。換言之，藉由集塵盒12的開口面受 到前蓋11的後面的按壓，集塵盒12被容納於外殼10內，並 維持該收納狀態。 外殻1 0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1 5的下端部爲具備有軸3 2，軸3 2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 -22- 201200092 朝向外殼10的軸方向前後旋動。過濾器15，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 向（重力作用方向）爲佳。過濾器1 5，例如爲高密度的 ΗEPA過濾器（High Efficiency Particulate Air Filter)。 所謂HEPA過濾器，爲對於在額定風量下粒徑0.3 // m的粒 子具有99.97%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，不設置於過濾器15的下端部，亦可設置於過濾器 1 5的上端部。 於外殼10，爲將集塵盒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1 2，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 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 -23- 201200092 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，減低吸入空氣的壓力損失，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，爲與外殼 10的軸方向一端面（前側端面）的開口面一致。亦即，集 塵盒12的開口方向，與外殼10之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，爲抵接於外殼10之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，爲被支撐於外殻10內。因此，集塵 盒12係以下部的軸14爲支點而可朝向外殼10的軸方向前後 旋動。藉此，從塵埃容納部5將前蓋11打開時，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 10之軸14的形成位置，由於爲與相對於外殻1〇之軸31的形 成位置相同側（下側），故從塵埃容納部5將前蓋1 1打開 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14，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打開時，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 -24- 201200092 用者可容易地排出蓄積於集塵盒12內之塵埃。再者，集塵 盒1 2，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12的一部分從塵埃容納部5彈出之 時，集塵盒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。由於除了外殼1 0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I2從塵埃 容納部5傾斜3 0 °彈出，所以可使蓄積於集塵盒1 2內之塵埃 朝向大致重力方向排出。 於前蓋11內，形成有朝軸方向貫通之外側流路35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 另一端爲連通於外殼1〇之特別是集塵盒12的開口。於電動 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，於電動吸塵器停止時，爲了防止蓄積於集塵 -25- 201200092 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35的內部或是另一端部’以形成覆蓋外側流路35之逆止 閥（圖示省略）爲佳。逆止閥’係以上端爲支點而朝向集 塵盒1 2旋動。不過’逆止閥並非爲必須之構成。外側流路 3 5的斷面積，爲從外側流路3 5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12 的外側朝向中心側方向。爲了抑制從外側流路3 5朝向集塵 盒〗2流入之空氣的紊亂，外側流路3 5的形成方向’以集塵 盒1 2的外側流路3 5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】〇之特別是集塵盒1 2的外側。內側流路3 6的另 —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，係與外 側流路3 5爲相反地，從內側流路3 6的一端朝向另一端縮小 〇 於塵埃容納部5的上部外側，具備有朝向水平方向延 伸之使用者可持住的把手16。使用者，手持該把手16，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，若將塵埃分離部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 -26- 201200092 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，麈埃容 納部5的軸方向另一端面（相當於過濃器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 ’以下部更接近於外殻1 〇側爲佳。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Η部分）的形成 方向，爲比垂直面（重力作用方向）更朝向外殻1 0側傾斜 40度〜45度左右。亦即’比起塵埃容納部5之軸方向一端 面的上部’下部更朝向外殼i 〇側接近。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，朝向塵埃分離部4上方 或是斜上方提起，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—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1卸取下來。又’並不僅只使用者將塵埃分離部4卸 取下來之場合，在將塵埃分離部4及塵埃容納部5作爲一體 -27- 201200092 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28側爲呈 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15的過 濾器構件79，將附著於過濾器1 5之塵埃抖落。如上述般， 由於過濾器〗5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 -28 - 201200092 塵埃，會蓄積於外殼10內。藉此，可抑制過濾器15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。 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。於電動送風機28的下游側且比電 動送風機28位於更前側處，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

m的粒子，爲具備有99.9995 %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，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。 其次，說明電動吸塵器之操作時（使用時）之空氣流 。第1圖中的箭頭，爲顯示空氣流。使用者將電動吸塵器 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 3 8處改向朝圓周方向。其結果，空氣’以外筒6的軸心爲 -29 - 201200092 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3 3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36，在外殼10內朝向集塵盒12的外 部下側流入，到達過濾器〗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。因此，集塵盒1 2，爲將外殼1 0內，區劃（分 隔）成連通於外側流路3 5之空間及連通於內側流路3 6之空 間。或，集塵盒12，爲將外殼1 0內，區劃（分隔）成連通 於外側流路3 5之空間及面對過濾器1 5之空間。於過濾器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15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 -30- 201200092 2 8的側部的排出口被排出的空氣，爲通過排氣導管4 〇，到 達過濾器29，而藉由過濾器29捕集殘留的塵埃。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

5以軸3 2爲支點朝向下側方向旋動打開。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11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1 1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，爲具備有可自由旋動 地被支撐於外殻10的軸31。前蓋11，爲呈大致圓形。第5 -34- 201200092 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11 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的上側時，爲了縮短外側流路3 5的長度減低空氣的 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】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場合，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 ，爲抵接於外殼1〇之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1 1 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，於電動吸塵器停止時，可防止蓄積於集塵盒12之塵埃 -35- 201200092 朝向外側流路35及塵埃分離部4逆流。不過’於包含前蓋 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之逆止閥（圖示省略） 爲佳。藉此，更於電動吸塵器停止時，可防止蓄積於集塵 盒1 2之塵埃朝向外側流路3 5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3 6 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 周端的下端。而，如第5圖（B)所示，於前蓋1 1的背面側 (塵埃容納部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 朝向另一端擴開。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1 1的外周端。如 -36- 201200092 第6圖所示，外殻10之軸方向一端面的開口的外 抵接於集塵盒1 2的開口的外周端的一部分。又 所示，外殻1 〇之軸方向一端面的開口的8 〇%以上 盒1 2的開口所占據。而，外殼1 0的開口之集塵盒 以外的區域（剩下20%左右以下），爲與內側流 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動吸塵器的 電動吸塵器，除了吸塵器本體1以外，爲具備有 50、及接頭管（延長管）51、及操作管52、以及 上述吸入具50爲具備有吸口，上述接頭管（延長 其一端爲連通於吸入具50且可自由伸縮，上述操 其一端爲連通於接頭管51的另一端，並具備有使 住之把手53或操作按鈕/開關，上述軟管54，其 通於操作管52的另一端，並於另一端形成有軟管 。於吸麈器本體1的本體吸氣口 21可插入、保持 管20。又，於吸塵器本體1的兩側面具備有輪子 藉由來自使用者對操作按鈕/開關的操作，將電 的電源ON時，則電動送風機28會動作產生吸引 入具50的吸口吸入空氣，便依序通過接頭管51、 、軟管54、軟管接頭管20，而流入吸塵器本體1。 第8圖，爲本發明之實施例的吸塵器本體1的 於吸塵器本體1的上表面的中央附近，爲具備有 可朝向吸塵器本體1轉動之方式被軸支撐的集塵眷 上護罩56，於比吸塵器本體1上表面的蓋56更後 周端，爲 ，如第6圖 ，爲集塵 1 2之開口 路3 6的開 槪觀圖。 :吸入具 軟管54 ; 管）51， 作管5 2， 用者所握 一端爲連 接頭管20 軟管接頭 5 5。而， 動吸塵器 力。從吸 操作管52 立體圖。 其一端以 I置2用之 側處，爲 -37- 201200092 具備有以可朝向吸塵器本體1轉動之方式被軸支撐之使用 者用以將吸塵器本體1提起的把手3 7。 根據本發明之實施例，不用煩勞使用者的手即可壓縮 塵埃，使用者可容易地排出經壓縮蓄積之塵埃，再者，可 抑制吸引力之降低。上護罩5 6，以形成爲在閉合狀態下可 覆蓋集塵裝置2的把手1 6之大小及形成於該相當位置爲佳 。再者，上護罩56，爲以在吸塵器本體1的動作中不能打 開之方式，該轉動被鎖住，或是上護罩1打開時吸塵器本 體1的動作會停止爲佳。藉由上護罩56，可防止於吸塵器 本體1的動作中使用者將集塵裝置2卸取下來，可提昇電動 吸塵器的安全性。 〔實施例2〕 將實施例1之內筒7的詳細，作爲實施例2予以說明。 本發明之實施例2的電動吸塵器，其特徵爲：集塵裝 置2爲將於圓周面具備有複數個貫通孔33的內筒7予以內包 起來，內筒7的軸方向之一端爲被封閉，內筒7的軸方向的 另一端爲呈開口並朝向電動送風機28側連通，內筒7的軸 方向之一端，爲形成於與集塵裝置2的入口管3的出口側開 口相向之位置。而，內筒7的軸方向之一端，係以使從集 塵裝顰2的入口管3吸入的空氣朝向圓周方向迴旋之方式構 成。 又或’本發明之實施例2的電動吸塵器，其特徵爲： 內筒7的軸方向之一端的封閉部，爲具備有：持有使從集 -38- 201200092 塵裝置2的入口管3吸入的空氣朝向圓周方向迴旋的功能之 形狀。 又或，本發明之實施例2的電動吸塵器，其特徵爲： 內筒7的軸方向之一端的封閉部，爲具備有朝向內筒7的軸 方向的內側凹陷之形狀（例如··凹陷部8 )，凹陷的形狀 之一部分，爲朝向內筒7的圓周面開呈口。 而，根據本發明之實施例2，藉由使內筒7的一端具有 迴旋功能，不用加大寬幅即可縮短集塵裝置2的軸方向的 長度，可使電動吸塵器更小巧。 第9圖，爲從圓筒部分側觀察本發明之實施例2的內筒 7之正面圖。內筒7的圓筒部分，爲由中空的半圓柱形狀的 圓柱部分5 7及中空梯形圓錐狀的梯形圓錐部分5 8所構成。 圓柱部分5 7，爲位於內筒7的圓筒部分的前端側，梯形圓 錐部分5 8 ’爲位於內筒7的圓筒部分的底部側。梯形圓錐 部分5 8的根底，爲接合於外延部3 4的內周端。藉由梯形圓 錐部分5 8，圓柱部分5 7及外延部3 4的接合部會變得較平緩 ’可抑制空氣流的剝離或亂流的產生，減低吸入空氣的能 量損失’又可抑制噪音。內筒7，以外延部34及引導管38 (引導構件）及圓柱部分57以及梯形圓錐部分58成形一體 爲佳。圓筒部分，若非爲由圓柱部分57及梯形圓錐部分58 所構成，亦可僅由圓柱部分57或是僅由梯形圓錐部分58所 構成。亦即，圓柱部分5 7可爲圓柱形狀，亦可爲圓錐梯形 狀。 R1爲圓柱部分57的外形半徑，R2爲梯形圓錐部分58的 -39- 201200092 外形半徑，R3爲外延部34的外形半徑’ R4爲引導管38的外 形半徑。外延部34的外形爲大致真圓。圓柱部分57的半圓 ，爲大致真圓。外延部34及圓柱部分57以及梯形圓錐部分 58，爲形成於同心軸上，並爲R1<R2<R3的關係。例如， R1爲3cm左右，R2爲5cm左右，R3，爲6.5 cm左右。引導管 3 8的軸心，相對於圓柱部分5 7的軸心，於第9圖爲位於朝 左側偏離處，爲R1<R4<R2的關係。例如，R4爲4cm左右。 圓柱部分57的圓周方向的一端（第9圖的下側）爲終端， 另一端（第9圖的上側）爲接合於引導管38。引導管38的 側壁，從圓柱部分57的另一端直至引導管終端部59的前面 爲止，曲率半徑爲R4且呈半圓形狀地平緩彎曲，引導管終 端部59的側壁，也是在圓柱部分57的外側沿著圓柱部分57 的外周（沿著梯形圓錐部分5 8的外周）平緩彎曲。亦即， 引導管3 8 ’其一端爲連結於凹陷部8的開口，而另一端爲 朝向在圓柱部分5 7的外側處沿著圓柱部分5 7的外周之方向 (沿著梯形圓錐部分5 8的外周之方向），其間使其轉向 1 8 0°地呈大致半圓形狀平緩彎曲。凹陷部8本身，以從凹 陷部8的側壁朝向底部中心沒有階段差，平緩地形成球狀 爲佳’從凹陷部8到引導管3 8的接合部，亦以沒有階段差 ’平緩形成爲佳。藉此，可減低吸入空氣的能量損失，又 可抑制噪音.。 圓柱部分5 7的厚度〇 1 (外形R 1與凹陷部8的側壁之間 )爲3mm左右，且3mm左右的厚度D1的內側，爲中空，該 空間爲連通於貫通孔3 3。圓柱部分5 7的一端部，由於形成 -40- 201200092 使空氣流轉向大致1 80度之流路的內壁，故較厚，爲較可 減低噪音。在此，相對於圓柱部分57的厚度D爲13mm左右 ’於圓柱部分57的一端部之厚度爲6mm左右，以作得較厚 較佳。亦即，將圓柱部分57之一端部的曲率半徑作成3mm 左右爲佳。藉此，可減低噪音。又，若也將圓柱部分57的 厚度D1作厚時，由於塵埃易於堵塞，故圓柱部分57的厚度 D1以3mm左右爲爲佳。凹陷部8的半徑（R1-D1 )，以與入 口管3的出口開口的內側半徑一致或是稍微（imm以內） 大爲佳。凹陷部8的半徑，若比入口管3的出口開口的內徑 還小，則塵埃會堵塞，或空氣的能量損失變大，故會有噪 音增加之虞。 貫通孔33，沒有形成於梯形圓錐部分58或引導管38, 以僅形成於圓柱部分5 7的外周面爲佳。不過，貫通孔3 3， 不僅於圓柱部分57的外周面，亦可形成於梯形圓錐部分58 或引導管38。貫通孔33的直徑亦可爲2mm左右。將貫通孔 33的直徑作成2mm左右時，貫通孔33的數目以100個左右 爲佳。 其爲引導管38的一部分之引導管終端部59，從半徑方 向觀察時，爲具備有從引導管終端部59的圓周方向根底部 60朝向引導管終端部59的圓周方向前端部61之大致「<」 字狀。如第9圖所示，引導管終端部59及圓柱部分57，若 從半徑方向觀察則爲重複。藉由引導管38的終端（引導管 終端部59)延伸至與圓柱部分57的一端重複之位置爲止地 形成，可賦予吸入的空氣充分的迴旋力。在相對於引導管 -41 - 201200092 終端部5 9爲圓周方向的相反側（1 8 0度相反側）處’形成 有外側流路3 5的一端開口（外延部3 4的上部的開口）。貫 通孔33，只要形成於從至少引導管終端部59到外側流路35 的一端開口之間即可。由於塵埃在外側流路3 5易於流動’ 故外側流路3 5的一端開口的圓周方向的長度以較長爲佳。 外側流路3 5的一端開口的下游側壁面65 (左壁面）爲比上 游側壁面6 6 (右壁面）還高，下游側壁面6 5，從軸方向觀 察時爲從內周側朝向外周側傾斜或是彎曲’外周側比內周 側更朝向上游側壁面6且於圓周方向較長。此爲’萬一頭 髮或棉絮等之具有長度的垃圾卡到下游側壁面65時，藉由 使外周側在圓周方向較長，將此等垃圾朝向內周側引導之 力會發揮作用，可慢慢地崩解平衡，將垃圾收到塵埃容納 部5之故。爲了抑制蓄積於塵埃容納部5之塵埃從前蓋11的 外側流路3 5的另一端開口散落，外側流路3 5的一端開口， 以配置於上側爲佳。在此，欲使離心分離距離更長時，可 將外側流路3 5的一端開口的位置保持不變，而將凹陷部8 的開口的形成位置及引導管終端部59的形成位置，作在順 時針方向且接近於外側流路3 5的一端開口的位置，於第9 圖爲作在左側的位置即可。 第1 〇圖，爲從圓筒部分側觀察本發明之實施例2的內 筒7之正面圖。箄10圖中的箭頭，爲顯示吸入空氣的流動 方向。於凹陷部8朝向大致軸方向流入之空氣，爲藉由凹 陷部8轉向朝半徑方向，藉由引導管38轉向朝圓周方向， 在內筒7與外筒6間之半周左右（亦即從引導管終端部5 9至 -42· 201200092 外側流路3 5的一端開口）朝向圓周方向及軸方向流動（迴 旋），流入之空氣的大部分爲流入外側流路3 5的一端開口 (氣流64 )。因此，凹陷部8及引導管38，爲具備有使流 入大致軸方向之空氣迴旋的功能。在內筒7與外筒6間之半 周左右（亦即從引導管終端部59至外側流路35的一端開口 )朝向圓周方向及軸方向流動（迴旋）的空氣的一部分’ 爲從貫通孔3 3流入內筒7內（氣流6 3 )。又，沒有流到外 側流路3 5的一端開口之空氣，在引導管3 8與外筒6間之半 周左右（亦即從外側流路35的一端開口至引導管終端部59 )朝向圓周方向流動（氣流64)，而與從引導管38出來的 空氣合流。於本發明之實施例2，由於在內筒7的外側迴旋 之空氣，會通過外側流路35，流入連通於電動送風機28之 塵埃容納部5，沒有必要把離心分離距離增長，只要半周 左右即可。因此，可將內筒7的高度，進而塵埃分離部4的 軸方向長度予以縮短，可縮短集塵裝置2的軸方向長度， 可將吸塵器本體1作得更小巧。塵埃分離部4的外形直徑， 爲大致相當於內筒7的外形直徑亦即外延部3 4的外形直徑 2R3。塵埃分離部4的軸方向長度（不含入口管3)，爲大 致相當於內筒7的軸方向高度H5。然後，具備有H5<2R3的 關係。因此，塵埃分離部4的軸方向高度，爲比塵埃分離 部4的上下寬幅或左右寬幅還小。例如，2R3爲13cm左右， 而H5爲7cm左右。把流入於外側流路35的一端開口之空氣 (氣流6 2 )的流量作爲流量V 1，從貫通孔3 3流入內筒7內 的空氣（氣流63 )的流量作爲流量V2，沒有流入外側流路 -43- 201200092 35的一端開口之空氣（氣流64)的流量作爲流量乂3時’具 備有V1>V2>V3的關係》又’相較於在入口管3之流速’在 引導管38之流速較高，相較於在引導管38之流速’在外側 流路3 5之流速較高。亦即，氣流6 2 ’在引導管3 8加速’在 外側流路也加速’分爲2段階加速。因此’相較於入口管3 的流路斷面，引導管38的流路斷面較小’相較於引導管38 的流路斷面’外側流路3 5的流路斷面較小。 半徑方向的流路寬幅W，相對於在引導管38的引導管 終端部5 9之流路寬幅W 1，在從引導管3 8出來的位置之流 路寬幅W2爲擴開，從引導管終端部59的出口到外側流路 3 5的一端開口爲止爲固定不變（流路寬幅W2 ) ’且從外 側流路35的一端開口到引導管終端部59爲止爲慢慢的從流 路寬幅W2到流路寬幅W3變窄，而於引導管終端部59成爲 流路寬幅W3。於是具有W2>W1>W3的關係。W3若太小’ 則塵埃會有堵塞之虞，因此例如W 3，爲1 . 0 cm左右。例如 ，\¥2爲113-111，且爲4(^左右。\¥1爲冒2-\¥3-(引導管終端 部59的半徑方向的厚度），且比3cm稍小。 第11圖，爲從圓筒部分側觀察本發明之實施例2的內 筒7之立體圖。引導管終端部59的側壁，並非與圓周方向 垂直地爲終端，而是以分爲2段階屈曲之大致「<」字狀 爲終端》具體上，從弓.1導管終端部59的軸方向前端部到軸 方向中間部爲止，爲接近於與圓周方向垂直之垂線的角度 爲終端，到引導管終端部的引導管終端部5 9的軸方向根底 部爲止爲比與圓周方向垂直之垂線更傾斜地爲終端。例如 -44- 201200092 ，引導管終端部59的側壁，若在引導管終端部59的圓周方 向根底部60的位置，與圓周方向垂直地爲終端時，不能賦 予充分的迴旋力，無法充分地分離塵埃。另一方面，若在 引導管終端部59的圓周方向前端部61的位置，與圓周方向 垂直地爲終端時，迴旋力會過強，在迴旋的第一周流入於 外側流路3 5的空氣即變少，塵埃不能被外側流路3 5 (特別 是比重較大的塵埃）吸入，會有塵埃殘留於塵埃分離部4 內之情形。特別是於本發明，由於塵埃分離部4的入口側 爲位於重力方向下，出口側爲位於重力方向上，故塵埃不 能被外側流路3 5吸入，因而於塵埃分離部4內塵埃殘存的 情形顯著。在此，藉由使引導管終端部59以大致「<」字 狀爲終端，對於流入凹陷部8之空氣，可賦予必須之充分 的迴旋力。再者，流入凹陷部8之空氣，由於會朝向軸方 向的下游側流動，故在引導管終端部59處觀察時，比起引 導管終端部59的軸方向前端側，軸方向根底側的流量較多 (壓力較高）。在此，比起引導管終端部59的軸方向前端 側，將軸方向根底側朝向圓周方向作得較長，藉此，對於 流量較多的引導管終端部59的軸方向根底側，可賦予充分 的迴旋力。又，代替引導管終端部59作成大致「<」字狀 ，亦可將引導管終端部59的側壁作成從軸方向前端側朝向 軸方向根底側以1段階朝向圓周方向慢慢地傾斜。 第1 2圖，爲從外延部背面側觀察本發明之實施例2的 內筒7之俯視圖。第1 3圖，爲從外延部背面側觀察本發明 之實施例2的內筒7之立體圖。墊片9(密封構件），爲藉 -45- 201200092 由3根螺絲6 7 (安裝構件）、安裝於外延部3 4的背面側。 墊片9，爲具備有位於外周側之圓環狀的唇部68 (突出部 )以及位於內周側之圓環狀的唇部69 (突出部）。唇部68 ，係爲了保持位於外側流路3 5之內筒7與前蓋1 1的氣密性 而設置，唇部6 9，係爲了保持位於內側流路3 6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 蓋11，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3 5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，可抑制麈埃卡住、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39 之墊片9所封閉，圆筒部分的內周側（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， -46- 201200092 形成內側流路3 6。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36的空氣之能量損失或噪音。 第1 4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 壁面65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。外側流路3 5的內壁面1 0 1，爲從 其爲外側流路35的入口之下游側壁面65朝向其爲外側流路 35的出口之內筒7的軸方向另一端面，朝向圓周方向傾斜 或是彎曲地形成。藉此，塵埃可平順地流動於外側流路3 5 內。又，由於外側流路3 5的內壁面1 0 1呈傾斜或彎曲，故 於從外側流路3 5出來的空氣流，不僅只軸方向的成分，亦 留有圓周方向的成分（迴旋成分）。 第15圖，爲從右側觀察本發明之實施例2的內筒7之側 面圖。外延部3 4，爲朝向外側流路3 5 (從下側朝向上側） ，軸方向的高度較低。外延部34的表面，於第1周，爲朝 向外側流路3 5形成螺旋狀。若將圓柱部分5 7的高度作爲Η 1 ，將在梯形圓錐部分58的最高位置之高度作爲Η2時，則具 有Η1>Η2的關係。又，若將在引導管38的最高位置之高度 作爲Η3時，則具有Η3>Η1的關係。貫通孔33，爲只要形成 於從至少引導管終端部59到外側流路35的一端開口之間即 -47- 201200092 可’其中’比起外側流路3 5側亦只要集中形成於引導管終 端部59側即可。於外側流路35側，由於比起流入貫通孔33 的流量，流入外側流路3 5的流量較多，故於外側流路3 5側 形成貫通孔33是沒有意義的》 第1 6圖，爲從右側觀察本發明之實施例2的內筒7之斷 面圖。若將凹陷部8的軸方向處之最深部分的深度作爲H4 時，則具有Η 4 < Η 1的關係。亦即，凹陷部8的深度，爲比 圓柱部分57的高度還淺。從立體角度來看，凹陷部8爲半 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Η4，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33的軸方向的形成位 置。凹陷部8的深度Η4若太深，則從貫通孔3 3被吸入空氣 的流量會變少，另一方面，凹陷部8的深度Η4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38的底面’從引導管38 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38，故若除去引導管38的部分，實際上凹陷部8 則係成爲W4球狀。 • 48 - 201200092 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33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3 3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 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17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5 7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3 8的軸方向前端部的全長’沿著 -49- 201200092 引導管3 8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D 2 > D 3的關係，因而產生（D 3 - D 2 )的階段差。例 如’ D2爲3mm左右，而D3爲2mm左右。因此，階段差，爲 1 mm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 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5 7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102的形成位置，亦可爲從引導管38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 •50- 201200092 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□距 離還小極多。如第1 7圖（b )所示’整流板1 〇2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102可爲1片，亦可爲複數片。於整流板 1 02與外延部3 4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 〇 2與外筒7的軸方向端面的內側之間亦 有較小的縫隙，該大縫隙亦有空氣流動。該整流板1 02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102的兩面產生流’故可抑 制在整流板1 02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1 〇2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。 201200092 〔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。 本發明之實施例3的電動吸塵器，其特徵爲：其第2集 塵部（例如：塵埃容納部5 )，爲具備有第1構件（例如：

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，亦可抑制第1集塵部及相對 於吸塵器本體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集塵部與吸塵器本體1之間的氣密 性，可抑制電動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。 又或，本發明之電動吸塵器，其特徵爲：其第2集塵 部（例如：塵埃容納部5 )，爲具備有第1構件（例如：突 起構件70 )，該第1構件爲於第1集塵部（例如：塵埃分離 部4 )側的軸方向一端部，具備有相對於吸塵器本體1的底 面呈大致垂直之面；其第1集塵部，爲具備有第2構件（例 如：凹陷部39 )，該第2構件爲在對應於第2集塵部側的軸 -52- 201200092 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集塵部與吸塵器本體1之間的氣密性，可抑制電 動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。 又，本發明之電動吸塵器，其特徵爲：具備有：中介 於第1集塵部（例如：塵埃分離部4 )與第2集塵部（例如 :塵埃容納部5 )所連通之部分的第1密封構件（例如：墊 片9)，以及中介於第2集塵部與吸塵器本體1所連通之部 分的第2密封構件（例如：墊片25 )，第1密封構件，相較 於第2密封構件，是以彈性力較大的材料所構成。而，根 據本發明，可保持相較於第2集塵部與吸塵器本體1之間爲 較易分離之第1集塵部與第2集塵部之間的氣密性，可抑制 電動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。 又，本發明之電動吸塵器，其特徵爲：具備有：中介 於第1集塵部（例如：塵埃分離部4.)與第2集塵部（例如 :塵埃容納部5 )所連通之部分的第1密封構件（例如：墊 片9)，以及中介於第2集塵部與吸塵器本體1所連通之部 分的第2密封構件（例如：墊片25 )，第2集塵部，爲藉由 -53- 201200092 第1密封構件及第2密封構件，被支撐於裝著有第丨集塵部 的吸塵器本體1。而’根據本發明，使用者可容易地將第2 集塵部從吸塵器本體1卸取下來，塵埃的排出操作變得較 容易。再者’根據本發明，可保持第〗集塵部與第2集塵部 之間及第2集塵部與吸塵器本體1之間的氣密性，可抑制電 動吸塵器之吸入工作效率的降低。再者，亦可抑制因空氣 浅漏引起之噪音的產生。 又’本發明之電動吸塵器，其特徵爲：具備有從集塵 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，可抑制電動吸塵器之吸入工 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。 又，本發明之電動吸塵器，其特徵爲：具備有將集塵

9圖，爲從右上側觀察本發明之實施例3 -54- 201200092 的吸塵器本體1之立體圖。特別是，顯示使用者將上護罩 56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1的面（例如：地板面） 爲垂直方向或是比垂直方向梢微前側之方向（例如：5度 )° —體成形於塵埃分離部4的入口管3的軸方向一端爲抵 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！ 。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裝著於吸塵器本體丨之狀態，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或吸麈器本體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 -55- 201200092 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，塵埃容納部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 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7 0。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7〇，與前蓋1〗爲相同材料，且以與前蓋 1 1一體成形爲佳，沒有一體成形也可以。突起構件70的前 -56- 201200092 端面，爲朝向大致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或 是朝向比垂直方向稍微前側之方向（例如：0〜5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3 9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70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 力不能再壓入時，將上護罩5 6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！將塵 埃容納部5卸取下來後，將塵埃分離部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 -57- 201200092 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3 9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 ，使用者，可容易地將塵埃分離部4從吸麈器本體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， 可將塵埃分離部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27的入口開口（輔助過濾器26 ) ’爲 靠近左側地形成。又，吸麈器本體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 -58- 201200092 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！ 浮起。亦即，塵埃分離部4的軸方向另一端，因被卡合構 件71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 口管3的軸方向一端抵接於墊片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7 2，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10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 〇側。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 -59- 201200092 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22圖般從側面觀察時之墊片25 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 1 5的後端面也傾斜角度b。相對於墊片2 5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（外殼 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25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25’以由 -60- 201200092 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2 5的黏性作得較低’ 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25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25。換言之，用彈性力比墊片25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25還大，而以墊片9的彈 性變形許容塵埃分離部4與塵埃容納部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7〇之前端 -61 - 201200092 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 〇側）。例如，角度C ’爲0〜5度之範圍內 的預定角度。因此，具有角度角度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設定成〇。亦即’只要 墊片25的後端面夠傾斜，則突起構件70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 起構件7 0的前端面雖是與凹陷部3 9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7〇的前端面 及墊片25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70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7 8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7 8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 -62- 201200092 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70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 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81，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 -63- 201200092 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 — 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 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Π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a。 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70的前端面，爲抵接於凹陷部39的前側壁面。 -64 - 201200092 突起構件7〇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2 8之 停止中，突起構件7 0的前端面與凹陷部3 9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28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3 9的前 側壁面會抵接於突起構件7 〇的前端面，限制塵埃分離部4 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7〇形成於前蓋11，將凹陷部39形成於內筒 7，亦可將凹陷部39形成於前蓋11，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6 7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75。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 -65 - 201200092 限制機構。 於前蓋1 1之軸方向一端面的最外周部，亦即對應於外 延部3 4之背面側的唇部6 8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 6 9之位置，形成有用以接受外延部3 4的背面側的唇部6 9之 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7 0 ，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70，爲由朝向左右 方向並列的2個突起構件70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70 ’亦可 由1個突起構件70所構成。又，亦可形成於墊片受部7*7的 外周且爲墊片受部76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 -66- 201200092 觀察本發明之實施例3的塵埃容納部5之正面圖。過濾器15 ，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2 8的前方壁面）中與過濾器1 5的框體7 8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81，於過濾器15形成 凹部8 1，亦可於吸塵器本體1的後側壁面形成凸部73。 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，形成有容納除塵裝置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2 6或容納部8 2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 -67- 201200092 實現了密封機構（密封構件）。 第2 7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 段差。 第2 8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〗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 —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 7 2的前端部的凸部，會抵接於卡合孔8 2的內側壁面並卡住 -68- 201200092 ，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8 2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 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1 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的電動吸塵器，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1 2 )從內包於通氣構件或外殻的第！ 狀態’朝向外殼的前方方向轉動至通氣構件的開口面與把 -69- 201200092 手的形成方向之形成角度（例如：角度e_角度f -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。 又或，本發明之實施例4的電動吸塵器，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 是相對於與吸塵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 於外殼的機構之強度，又可抑制外殻的撓彎。 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，及在集塵盒12內之塵埃83的蓄積狀態。 如第2 6圖所示般’吸氣導管2 7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（ -70- 201200092 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1〇圖所般’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3 5 ’並藉由下 游側壁面6 5而轉向朝軸方向。但是即使藉由下游側壁面6 5 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35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 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1 1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 1 2內之氣流62，不僅只直接被朝向過濾器1 5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1 2的右側壁面，在朝向集塵盒1 2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62 (從上面看塵埃容納部5時，爲順 時針方向之迴旋）。特別是於集塵盒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 -71 - 201200092 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8 3爲從右側蓄積，故即使於集塵盒1 2內蓄 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83 的蓄積引起之吸引力的降低。又，於塵埃83從集塵盒12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殻1 〇，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1 1的軸方向另一端面（外側流路3 5的出口開口）之集 摩盒12內的位置，亦突然放大。因此，氣流62，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12內的位置亦突然變慢並擴散。 -72- 201200092 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12的軸方向，由於相對於過濾器 I5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15。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1 5 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84的下端。而 ，流入集塵盒1 2內的氣流6 2，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1 2的上側壁面，爲位於集塵盒1 2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87。突起構件87，係以朝向其爲集塵盒12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 -73- 201200092 構件8 7，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 撐構造。第3 1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 0，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85而安裝於外殼10的內側。藉此，可抑制外殼10 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 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（從外殻10的下表面之在外殼 10內朝向斜向方向延伸形成的部分），而將安裝構件85固 定於外殼1 〇。然後，於安裝構件8 5的前側支撐軸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8 5，相對於 塵埃容納部5或是外殻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及外殻19, 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 -74- 201200092 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，吸麈器本體1 的前後方向的長度也變長。若將安裝構件85本身縮短時， 用以將安裝構件85固定於外殼1 0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8S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 安裝構件85作長（集塵盒I2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85，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1〇連同安裝構件85—起將集塵盒 12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1〇，前蓋Π爲呈打開 ，集塵盒12朝向外殼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殼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殼10 -75- 201200092 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，外殼 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 0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 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U，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11，相對於外殼10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，伴隨從外殻1〇的彈出，以形成於集塵盒的 底部8 4的中間的外側軸1 3爲支點分割成集塵盒的上半部8 8 及集塵盒的下半部89，集塵盒的上半部88及集塵盒的下半 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88的外側之突起構件87 (集塵盒12 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昀彈出受到限制。藉由該限制，集塵盒的下半 部89的前側端面，相對於外殻10的軸方向一端面，最大爲 打開角度f。例如’角度f爲33度左右。又，集塵盒12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 -76· 201200092 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8 9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（11.5 + 7) =18.5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1 2之塵埃8 3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U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 -77- 201200092 ，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16的前側將集塵盒I2內的塵埃83予以排出之 情形時，集塵盒之上半部88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〗2所蓄積的塵埃83容易地落下。不過，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，外殼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15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Π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9〇的形 -78- 201200092 成位置，設在使塵埃83不會從前蓋11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10來取代其形成在前蓋1 1。 第3 4圖，是從本發明之實施例4之塵埃容納部的右側 所觀察的斷面圖。第34圖（a)，是顯示集塵盒〗2的全開 狀態，且第34圖（a )，是顯示集塵盒12的半開狀態。如 在上述所說明過，突起構件87，是抵接於外殼10之軸方向 一端面開口的內側，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12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9 1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9 1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9 2之左邊（前側面）的傾斜角 -79- 201200092 ，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9〇度（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朝向外殼10的前方彈出之情形時’由 於是藉由集塵盒12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 件91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容納於外殼1 0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12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〗之軸方向一端面施加按壓 力，使前蓋1 1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9 1的左邊，使集塵盒1 2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 -80- 201200092 斜，所以即使前蓋11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9 3，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 容納於外殼10內，前蓋11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10 內，在打開前蓋1 1的狀態下，可以將集塵盒1 2容納於外殼 10內。使用者，然後，可以關閉前蓋11。藉此，使用者， 只要進行將集塵盒1 2容納於外殼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1〜4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 -81 - 201200092 1〜4，在實施例5中，是在內筒7的軸方向前端部追加定位 用的肋條96此點爲其特徵。相對於實施例1〜4，在實施例 5中，是在內筒7之墊片9的外周面之中的下側追加定位用 的凸部98此點爲其特徵。相對於實施例1〜4，在實施例5 中，是在前蓋1 1內的外側流路3 5內形成朝向軸方向延伸的 肋條1 04，使外側流路3 5於上側變狹窄此點爲其特徵。相 對於實施例1〜4，於實施例5，是在前蓋1 1的墊片承受面 76及墊片承受面77之間追加與外部連通的貫通孔105此點 爲其特徵。 亦即，本發明，其特徵爲：第1集塵部（例如，塵埃 分離部4)，是把於圓周面具備有複數個貫通孔的內筒7, 內包於大致圓筒狀的外筒6內，且於內筒之第2集塵部側的 端部（例如，軸方向底部側端部）與外筒6之間具有密封 構件（例如，墊片9 )，密封構件之第2集塵部側的端部， 是朝向外周側延伸（外延部94 )。藉此，可以充分地確保 內筒的第2集塵部側的端部與外筒的氣密，並可以減低空 氣的能量損失或是減低噪音。 又或是，本發明，其特徵爲：第1集塵部（例如，塵 埃分離部4)，是把於圓周面具備有複數個貫通孔的內筒7 ，內包於大致回筒狀的外筒6內，並具有從內筒7之本體吸 氣口側的端部（例如，軸方向前端側端部）朝向內筒7的 外周面所形成的流路（例如，凹陷部8及引導管3 8 ) ’且 在外筒6之本體吸氣口側之端部的內面之中與流路的側壁 相向的部分，具有突起構件（例如，肋條9 5 )。藉此’可 -82- 201200092 以充分地確保內筒的本體吸氣口側的端部與外筒的氣密， 並可以減低空氣的能量損失或是減低噪音。 又或是，本發明，其特徵爲：第1集塵部（例如，塵 埃分離部4)，是把於圓周面具備有複數個貫通孔的內筒7 ’內包於大致圓筒狀內，並於內筒7之本體吸氣口側的端 部（例如’軸方向前端側端部）之中的下側，具備有突起 構件（例如，肋條96 )。藉此，在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，而使內筒可容易 裝著於外筒內。 又或是，本發明，其特徵爲：第1集塵部（例如，塵 埃分離部4)，是把於圓周面具備有複數個貫通孔的內筒7 ，內包於大致圓筒狀的外筒6內，並於內筒7之第2集塵部 側的端部（例如，軸方向底部側端部.）與外筒6之間具有 密封構件（例如，墊片9 )'，密封構件的外周面之中的下 側，具備有突起構件（例如，凸部98 )。藉此，在將內筒 裝著於外筒內時，容易進行外筒與內筒之相對性的定位， 而使內筒可容易裝著於外筒內。 又或是，本發明，其特徵爲：第2集塵部（例如，塵 埃容納部5)，其與第1集塵部（例如，塵埃分離部4)連 通之流路（例如，外側流路3 5 )的下側壁面，是藉由朝向 軸方向延伸的突起構件（例如，肋條1 04 )所形成。藉此 ，可以抑制蓄積在第2集塵部內的塵埃朝向第1集塵部側逆 流、或是散落。 又或是，本發明，其特徵爲：於第1集塵部（例如， -83- 201200092 塵埃分離部4 )與第2集塵部（例如，塵埃容納部5 )連通 的部分（例如，前蓋11)，爲具有：把第1集塵部及第2集 塵部連通之流路（例如，外側流路3 5 )與集塵裝置2之外 部（例如，大氣）予以連通的孔（例如，貫通孔1 05 )。 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3 5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 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 _ 84 - 201200092 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 外壁厚度梢小若干、或是稍大若干亦可。並且，內筒7被 插入於外筒6內時’使墊片9的外周面’抵接於外筒6之外 壁的內周面，使外延部94之軸方向前端側的面’抵接於外 筒6之軸方向底部側的端面。亦即，將外筒6之軸方向底部 側的端面成爲覆蓋於墊片9。藉由外延部94，使得在軸方 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36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）95。肋條95， 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9 5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 -85- 201200092 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 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95 ，也可以不形成在對應於內筒6之軸方向前端部的部 。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#胃7 時，肋條95的內周面，是與引導管38之軸方向前端部的外 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95，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）96。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35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 -86- 201200092 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96形狀相對應之形狀的卡合孔97。卡合孔97， 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 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 -87- 201200092 ，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 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99。凹部99，是形 成在：當將內筒7裝著於外筒6時，對應於凸部9 8的位置。 凹部99，係具備有對應於凸部98的形狀。凸部98，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96更下側位匱的 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9 6及卡合孔9 7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9 8形成於內筒7之墊片9的外周面，將 -88- 201200092 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9 9形成於內筒7之墊片9的外周 面，而將凸部9 8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 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76及墊片承受面77、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3 9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1 04。肋條1 04，是從前蓋1 1內 的則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 -89 - 201200092 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1 04 製成大致L字型形狀，使肋條1 〇4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1〇4，是被 隱蔽在逆止閥103的內側’所以以點線表示。如第39圖所 示，肋條1 04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 ，可以抑制蓄積在集塵 盒12內的塵埃從外側流路35散落。又，藉由肋條1〇4，從 外側流路3 5所流入的氣流6 2，由於是朝向上方向，也就是 集塵盒1 2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，形成有逆止 閥103，該逆止閥103只覆蓋住在肋條104的上側所形成之 外側流路3 5的出口開口。且逆止閥1 03，是以上端作爲支 點而朝向集塵盒1 2旋動。逆止閥1 03，以由彈性材料，例 如橡膠所構成爲佳。藉由該逆止閥1 03，可以防止蓄積在 集塵盒1 2內的塵埃從外側流路3 5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1〇5’是形成在 前蓋11之左側之中的墊片承受面7 6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 -90- 201200092 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1〇5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 1 〇 5，是與前蓋1 1的外部（大氣）連通。亦即’貫通孔1 0 5 ，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3 5連通之則蓋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。 如第41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35連通之前蓋1 1的內側’然後 通過前蓋U之前壁的貫通孔1〇5 ’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 06 ’通過外側流路 3 5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1 〇〇，而流入唇部6 8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35之內筒7之 -91 - 201200092 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35之終端之 內周側的部分1 〇〇所牽絆住之情事。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。 〔實施例6〕 將實施例5所示之前蓋11的其他形狀，作爲實施例6予 以說明。 本發明之贲施例6的電動吸塵器，其內筒7之軸方向的 一端，係以將含有從集塵裝置的入口管被吸入的塵埃之空 氣，使朝向圓周方向迴旋之方式構成，而迴旋之空氣，通 過設置於前蓋1 1的外側流路3 5，並迴旋於集塵盒1 2內。然 後，塵埃會蓄積於集塵盒1 2內，空氣則被朝向電動送風機 側吸引。本實施例6，其特徵爲：藉由使前蓋1 1之外側流 路35的兩端，與集塵盒12的內壁形狀接續之方式形成，來 減低集塵盒12內之迴旋的紊亂。又或，本發明之實施例6 的電動吸塵器，其特徵爲：於外側流路3 5與內側流路3 6之 兩方設置逆止閥，在丟棄垃圾之際抑制塵埃之散落，並且 ，外側流路3 5側之逆止閥，爲藉由在前蓋1 1的外周側設置 支撐部，將支撐位置作爲逆止閥的中心，且支撐寬幅作成 逆止閥寬幅的2/3之形狀，來將進入集塵盒12的空氣流予 -92- 201200092 以整流。 又或，本發明之實施例6的電動吸塵器之特徵爲：集 塵裝置，具備有：藉由其一部分開口而其他部分具有通氣 性構件（例如，網目構件1 09 )所覆蓋之集麈盒1 2、及配 置於集塵盒I2的下游側之過濾器15、以及將本體吸氣口與 集塵盒12的開口予以連通之流路（例如，外側流路35 ); 流入流路內之空氣，爲藉由流路而迴旋，並到達集塵盒1 2 的開口，流路之出口端的一部分，爲在製造誤差範圍內近 接於集塵盒之開口的一部分。 而，根據本發明，可提高容納於集塵盒12的塵埃之壓 縮性，並且可減少通過集塵盒1 2的塵埃量，可抑制集塵盒 的容積。 第42圖，爲從本發明之實施例6的前蓋11，且不具逆 止閥之狀態下觀察塵埃容納部內側之正面圖，第4 3圖爲 從塵埃容納部內側觀察前蓋1 1之正面圖，又第4 4圖，爲 從塵埃容納部外側觀察前蓋1 1之正面圖。 前蓋11，係設有由透明的ABS樹脂等之材料所形成之 可確認集塵狀況的窗74。由肋條104所形成之下側的空間 1 〇4a，爲在集塵盒1 2內的塵埃變滿時會慢慢蓄積塵埃，因 此是爲了通知垃圾丟棄的時期而設置。空間1 〇4a，其集塵 盒1 2側的面爲開口，另一面是被閉塞。又，由於空間1 〇4a 爲夾著肋條1 04，比外側流路3 5配置於更靠近其斷面爲大 致圓形的前蓋1 1之中心側，故空間l〇4a之集塵盒12側的面 的開口，其面積爲比外側流路35的出口端（集塵盒1 2側） 93 - 201200092 的面積還大。又，由於比第3 8圖及第3 9圖所示之外側流路 35的形狀更朝左右方向將兩端擴大，故與窗74間的空間變 小，更易於把握集塵狀況。 如第42圖所示，外側流路3 5之出口端的開口形狀，爲 大致梯形或是大致半月形。不過，外側流路3 5之出口端的 開口形狀，亦可爲大致長圓形、大致橢圓形，大致長方形 、多角形。如第29圖所示，集塵盒12之入口端的開口形狀 ，爲大致八角形或是大致長圓形。不過，集塵盒12之入口 端的開口形狀，亦可爲大致圓形、大致橢圓形、大致長方 形、多角形。 如實施例5所示，於外側流路3 5設置橡膠製的逆止閥 。再者，於本實施例6，對於內側流路3 6亦設置橡膠製的 逆止閥，亦可抑制從內側流路36側之塵埃的散落》外側流 路35之逆止閥107作成板厚1.0mm，內側流路36的逆止閥 108，作成板厚0_5mm。亦即，內側流路36之逆止閥108的 板厚，爲以比外側流路3 5之逆止閥1 07的板厚還薄較理想 。此爲，內側流路3 6的流量，爲比外側流路3 5還少之故， 且逆止閥108的板厚，若太厚則抵抗會變大，會嚴重妨礙 氣流。關於逆止閥108的板厚，爲只要不會抵抗過大，於 吸引時可轉動之構造，則不限於此。又，逆止閥108，爲 藉由固定件l〇8a及螺絲108b而固定，形成得比從內側流路 36的外側觀察之開口面積還大若干。因此，以固定件108a 爲支點僅朝向集塵盒1 2存在之方向轉動。又，設置於外側 流路3 5的逆止閥1 07，係於前蓋1 1的外周側設置支撐部 -94- 201200092 l〇7a，並將支撐寬幅作成逆止閥107之寬幅的2/3，在逆止 閥107的中心處支撐。此爲，以支撐部107a爲支點，在吸 引時，藉由迴旋方向的面會上提，可抑制流入方向，具有 將流入之空氣予以整流之效果。支撐部1 〇 7 a，在外側流路 3 5的形狀上’於本實施例6爲作成前蓋丨！的外周側，不過 即使設置於對面側亦可得到相同的效果。又，逆止閥1 〇 7 的支.撐寬幅，爲只要以支撐部107a爲支點可朝向迴旋方向 轉動，則不限於此，2/3以下或以上皆可。於吸引時，必 須爲可耐得住施於逆止閥107的剪斷力之尺寸，且於本實 施例6 ’爲將支撐寬幅作成2/3。又，支撐寬幅雖爲2/3左右 ，不過如圖般係以3點支撐。此是爲了減輕逆止閥107的轉 動之故’且如前述般，只要爲能耐得住吸引時施於逆止閥 1 07的剪斷力之尺寸，可得到所需之轉動範圍，則並不限 於此。又，亦可將支撐位置不作在逆止閥1 07的中心，而 是靠近左右之任一方，不過在迴旋方向側沒有設置支撐部 〇 第46圖，爲將前蓋11閉合之狀態的第45圖之A-A斷面 。外側流路3 5之出口端的左右方向之兩端，爲作成在段差 較少之狀態下與集塵盒12之入口端的左右之內壁接續的形 狀。所謂段差較少之狀態，意指在製造誤差範圍內近接之 狀態。亦即，製造誤差（1 mm前後）程度，爲外側流路3 5 可比集塵盒12的內壁大（寬）亦可小（窄）。爲了減低空 氣流的紊亂，位於上游側之外側流路3 5，以比位於下游側 之集塵盒12的內壁還小爲理想，不過只要在製造誤差程度 -95- 201200092 內則較大亦無妨。接續於集塵盒12的內壁之部分，亦可爲 僅迴旋方向側（第42圖之外側流路3 5的右側），但以外側 流路35兩端都接續之形狀較爲理想。如第45圖所示，外側 流路35之出口端的上下方向之上端，也作成在段差較少之 狀態下與集塵盒12之入口端的上側內壁接續之形狀。又， 如第46圖所示，若觀察上下方向之斷面，可知外側流路3 5 之側壁面的出口端之形成方向，爲沿著塵埃容納部5之軸 方向（大致平行）的方向，另一方面，集塵盒12之側壁面 的入口端之形成方向，並非爲沿著塵埃容納部5的軸方向 之方向，而是從集塵盒12的入口端隨著越朝向內側越朝中 央側傾斜之方向。因此’外側流路3 5之側壁面的出口端之 形成方向，並無與集塵盒12之側壁面的入口端之形成方向 —致。不過，外側流路3 5之側壁面的出口端之形成方向， 以與集塵盒12之側壁面的入口端之形成方向一致爲佳。一 致時，從外側流路35出來的空氣，會流入集塵盒I2之大致 切線方向。 第46圖中所示之箭頭，爲在集塵盒12內迴旋之空氣流 。迴旋於內筒7的外周並通過外側流路3 5之空氣流1 1 0a ’ 會一面迴旋一面流入集塵盒12內。因此’如第46圖所不’ 觀察在上下方向之某斷面’可以看到空氣流1 1 0 a從右到左 流動於外側流路3 5內。於外側流路3 5之出口端附近’空氣 流1 1 0a會衝突於外側流路3 5內之左側側面’並流入集塵盒 1 2內。進入集塵盒1 2內的空氣流1 1 〇 a，如從空氣流1 1 〇 b到 空氣流1 1 〇c般，沿著集塵盒1 2的內側形狀（內壁）迴旋’ -96- 201200092 使空氣流ll〇c與入口之空氣流110a的衝突變少之方式迴旋 。藉由作成如此之外側流路3 5形狀，可減低集塵盒1 2內之 空氣的紊亂。相對於此，於第38圖（實施例5)所示之前 蓋11的形狀，會成爲第47圖所示之空氣流。第47圖，爲與 第45圖同樣在A-A斷面裁切之第38圖的斷面圖。外側流路 35’在與集塵盒12的內壁之接續上有很大的段差，進入集 塵盒12內的空氣流111a，沒有沿著集塵盒12的內壁面，是 大致垂直衝突於集塵內側12a，而分爲空氣流111b及流 111c之主要爲左右方向之不同的二個方向。空氣流lUc變 成空氣流llld而迴旋於集塵盒12內，由於與入口的空氣流 1 1 1 a從大致垂直方向合流，故有迴旋紊亂之傾向。 第48圖，爲在作成外側流路3 5之兩端接續於集塵盒1 2 的內壁之形狀（第46圖）之場合，與形成比集塵盒12的內 壁位於更內側之外側流路35之形狀（第47圖）時之集塵容 量的比較。其爲顯示從設置於前蓋1 1的窗74確認集塵狀況 ，並在判斷爲裝滿時，亦即塵埃已到達垃圾丟棄線90時之 集塵容量與開放風量的關係者。吸引過之塵埃，爲模擬一 般家庭之塵埃者，係相對於纖維塵1，混合以2倍的砂塵者 。從第4 8圖可得知，作成本實施例6 (第4 6圖）之形狀者 ，爲可持續同等風量，且集塵量增加約1 · 5倍，觀察實際 的集塵狀況，在集塵盒12內的塵埃也是均等地堆積。因此 ，根據本實施例6之外側流路3 5的形狀，可使塵埃的壓縮 性提昇。 又’加入相對於集塵盒12的網目構件1〇9爲垂直方向 -97- 201200092 的空氣流（力）之場合，從空氣流方向觀察之網目構件 109的開口面積爲最大，故顯示於第47圖之集塵盒12內的 空氣流，有細微塵埃易於通過集塵盒12的網目構件109之 傾向。其爲細微塵埃通過集塵盒1 2的網目構件1 〇 9時，會 蓄積於過濾器1 5之構造，在維修時（丟棄垃圾時），以通 過過濾器15的塵埃較少爲佳。第46圖所示之集塵盒12內的 空氣流，如前述般爲沿著集塵盒1 2，故可減低塵埃相對於 網目構件1 09爲朝垂直方向衝突之空氣流，可減少通過網 目構件109的塵埃量。 第49圖，爲把在作成外側流路3 5之兩端接續於集塵盒 12的內壁之形狀之場合（第46圖），與顯示於第47圖之形 狀時之從集塵盒12通過之塵埃的量作比較者。從該圖可確 認：作成本實施例6 (第4第6圖）的外側流路3 5之形狀時 ，通過網目構件109的塵埃量減少。因此，根據本發明之 實施例6，提高了容納於集塵盒12之垃圾的壓縮性，並且 可減少通過集塵盒12之塵埃量，藉由將集塵盒12的容積抑 制於最小，可使吸塵器本體1小巧化。從集塵盒1 2排出塵 埃之次數減少，可省卻使用者的麻煩。又，除去塞在過濾 器15的塵埃（細塵）之次數（清掃過濾器15之次數）也減 少，可省卻使用者的麻煩。

Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an electric vacuum cleaner, particularly to a cyclone type electric vacuum cleaner. [Prior Art] As a prior art patent, it is described in Document 1 that a dust storage chamber is disposed on the lower side of the dust separation chamber, and dusty air outside the suction cylinder in the dust separation chamber flows into the dust storage chamber, and is removed in the dust accommodation chamber. After the old mass of coarse sand garbage, etc., 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 electric filter of the second filter is absorbed by the electric blower. vacuum cleaner. 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-like mesh filter and the pleated filter are rotated and opened at the lower end. Patent Document 3 discloses a dust container in which dust is collected inside the dust collecting case to collect dust of the -5 - 201200092, and the dust container is discarded when the dust accumulated in the dust container and compressed by the suction is discarded. The lower end is an electric vacuum cleaner that is ejected from the dust collecting casing and disintegrated into the upper and lower sides while the shaft is rotated. Patent Document 4 discloses that one 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 is provided with a cyclone dust collecting device in the downstream direction of the dust collecting box at one end of the dirt discharge port. Patent Document 5 describes an electric vacuum cleaner including a cyclone that is disposed to extend horizontally so that the rotary shaft of the swirling flow generated inside the cyclone portion extends substantially in the horizontal direction. Further, in Patent Document 5, it is described that a dust-containing air from a floor suction port becomes a swirling flow when passing through a half-circumferential flow path of the cover of the cyclone, and the intervening opening is introduced into the cyclone portion, and then along the edge. With the inner peripheral wall of the cyclone dust collector, the dust is separated from the air by the umbrella-shaped partition plate of the middle cylinder, and is collected by the dust collecting portion, and on the other hand, is purified by the aforementioned swirling flow. The air was first purified through the mesh filter, and then passed through the inside of the middle cylinder for the second time. The filter, the air that enters the dust collecting part together with the dust, compresses the dust inside the dust collecting part when passing through the mesh filter for the first time, and the air that is purified by the mesh filter for the first time. The filter is reached twice, and then the air passing through the inside and outside of the middle cylinder is filtered by the filter -6-201200092 twice to reach 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. Then, in the special. Patent Document 6 discloses 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 forming portion. a semi-columnar convex portion that protrudes inward in the forward direction, and a plurality of through-holes for ventilation are provided on the circumferential surface of the semi-cylindrical convex portion on the circumferential surface downstream of the semi-cylindrical convex portion, and enters from the air inlet. The air and dust mites in the buffer space mainly flow toward the downstream side along the swirling flow path forming portion toward the right side, and swirl around the convex portion, and a part of the swirling air is aeration through the majority formed in the convex portion. Use a small hole and move 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 thereof is disposed obliquely to the electric blower side, and therefore, the dust collecting case is provided Body 201200092 An electric vacuum cleaner that is pressed against the body of the cleaner to easily obtain airtightness and is easy to attach and detach the dust-separating dust collecting portion 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 accommodating chamber which is formed so as to be inclined toward the front side as the front side wall surface is formed upward, and the rear side wall surface is formed substantially vertically, and the dust collecting device accommodating chamber becomes more and more as it goes upward. Widely formed, and in the accommodation of the dust collecting device, the electric dust collector that can guide the dust collecting device to be smoothly received.

Here, in place of the first filter of Patent Document 1, the dust container of Patent Document 3 is provided in order to open the upper side of the filter, but in Patent Document 1, the air flowing into the dust receiving chamber is from the lower end of the suction tube. When the opening is sucked in, the dust accumulated in the dust container of the patent document 3 is also sucked from the lower side of the air suction cylinder together with the air, and as a result, the amount of accumulated dust accumulated in the first filter before the electric blower increases. The attraction is reduced. In Patent Document 2, since the separation chamber and the dust accommodation portion are arranged in parallel, the diameter of the separation chamber and the inner cylinder thereof cannot be enlarged, and thus the dust is increased in the dust accommodation portion and is further increased from the separation chamber. The inner cylinder performs a desired degree of suction, and the pressure loss of the intake air is increased. As a result, the suction force is lowered as compared with the initial state in which the dust is not accumulated. Further, in Patent Document 2, since the mesh-shaped mesh filter is planar, there is a possibility that the user cannot easily remove the dust adhering to the mesh-shaped mesh filter. Here, in place of the mesh-like mesh filter of the patent document 2, the dust container of the patent document 3 is considered, but the dust-9 - 201200092 of the patent document 3 is in the shape of a container, and it has a dust collecting case. The shape of the back becomes bigger. Further, when the user holds the handle of the patent document 2 to open the rear portion of the dust collecting case, the direction in which the dust container of the patent document 3 is ejected is close to the (handle) side for the user, so that the inside of the dust container is provided. The dust is caught in the rear portion of the dust accommodating portion of Patent Document 2 and cannot be smoothly discharged. Further, the dust accommodating device itself collides with the rear portion of the dust accommodating portion and the dust accommodating device itself cannot be smoothly ejected. Further, in Patent Document 3, even if the dust container is ejected from the stack casing, the rear portion of the dust container abuts against the dust collecting casing, so that the opening direction of the front side of the ejected dust container is formed in a horizontal direction. The direction is closer to the vertical direction, and dust remains in the dust container. Further, in order to make the opening of the front side of the dust container face downward, the user has to turn the wrist in the direction toward the lower side, and the burden on the user becomes large. Further, 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 case, the strength is insufficient, or the lower surface of the dust collecting case is curved to impair the appearance. In Patent Document 4, since the turning force applying means is necessary in order to generate the cyclone flow, the length of the cyclone dust collecting device in the axial direction is long, and as a result, the length of the cleaner body in the front-rear direction becomes long. For example, when the dust box is disposed adjacent to the axial direction with respect to the cyclone body, the length of the cyclone dust collecting device in the axial direction becomes longer, and as a result, the length of the front and rear direction of the cleaner body becomes more long. Further, in Patent Document 4, since the flow path is increased from the contaminated air suction port and the flow velocity is lowered, the swirling force of the polluted air is imparted, so that the swing speed is slowed and the centrifugal force is lowered, and the polluted air may not be sufficiently accommodated. Separation. Further, in the case of the tube portion from the turning force applying means to the discharge port, the multiple return energy loss between the turning force applying means and the cylindrical portion of the discharge port is large, and noise is generated. In addition, since the turning force imparting means is composed of a plurality of wings (the air energy loss is large, and there is also noise generated in Patent Document 4, since the row is discharged from the swirler body without being disposed from the dust collecting box) The gas is only equivalent to the inner cylinder, so the energy loss of the exhaust air is large. Moreover, the dust containing the dust that is stored in the dust box is not provided in the special spear. Since the flow path for generating the swirling flow is formed at the front end of the intermediate cylinder, the length of the cyclone dust collecting (axial direction) becomes long, and as a result, the length in the front-rear direction becomes longer. Since the shape of the portion of the neutral mesh filter is a triangular pyramid, the downstream side of the direction (axial direction) approaches (as approached from the bottom of the triangle), the dust is more likely to adhere to the primary mesh, and the attractiveness is lowered. In Patent Document 6, since the buffer space and the swirling flow path forming portion are formed on the side of the semi-cylindrical convex portion, the length in the direction (up, down, left, and right) is long, and the front portion of the cleaner body is high The degree and the lateral width become smaller than those of Patent Document 7 and Patent Document 8' which do not describe the sound of the document 4, which is formed by the long "and the air is swirled" and the air is formed in the patent document. In addition, the external exhaust port has a small diameter of the exhaust port J. According to the means, the horizontal direction of the front cover of the dust collecting body has the vacuum cleaner body ί formed one time toward the top of the horizontal cone. The radius of the outer dust collecting chamber in the direction of the surface radius of the filter is likely to be large. Wind separation cylinder and set -11 - 201200092 The sealing mechanism between the dust casings, therefore, the direction of formation of the elastic seal portion with respect to the exhaust side opening of the dust collecting casing (non-vertical direction, the upper side is inclined to the electric blower side) When the joint surface of the cyclone separation drum and the dust collecting casing is largely inclined, only the sealing member may be interposed between the cyclone separation drum and the dust collecting casing, and sufficient airtightness may not be obtained. Here, an object of the present invention is to provide a compact electric vacuum cleaner which can secure a sufficient dust collecting capacity without increasing the volume of the dust containing portion. Still further, an object of the present invention is to provide a method for reducing the amount of dust which is swirled in the dust containing portion and reducing the amount of dust passing through the mesh filter of the dust collecting box of the dust containing portion, thereby suppressing the scattering of dust when the garbage is discarded. Electric vacuum cleaner. In addition, it is an object of the present invention to provide an electric vacuum cleaner which can prevent the dust accumulated in the second dust collecting portion from flowing back toward the first dust collecting portion side or being scattered. [Means for Solving the Problem] The present invention is characterized in that the first flow path (for example, the outer flow path) of the lid portion (for example, the front cover) provided in the second dust collecting portion (for example, the dust containing portion) is formed. , with the width of the dust accommodating part (for example, the shape of the dust box).

Alternatively, the present invention is characterized in that the dust collecting device includes a member that is partially open and has a ventilating portion in other portions (for example, a dust collecting box covered by a mesh, and a filter disposed on a downstream side of the dust collecting case, a flow path (for example, an outer side) that communicates with the opening of the body and the opening of the dust box: the air that flows into the flow path is swirled by the flow path and reaches the opening of the set, and a part of the outlet end of the flow path is manufactured The error range is connected to a part of the opening of the dust box. Preferably, at the end of the right end of the outlet end of the flow path, at least the end of the downstream side of the swirling air is close to the dust box within a manufacturing error range. The end portion of the opening in the left-right direction is less than the end portion. More preferably, the two end portions in the left-right direction of the outlet end of the flow path are respectively two end portions that are adjacent to the right direction of the opening of the dust box in the manufacturing error range. [Effects of the Invention] According to the present invention, by making the shape of the flow path of the front cover provided in the second dust collecting portion and the width of the dust collecting shape, the disorder in the dust collecting box can be reduced, and the dust collecting can be improved.

The opening is oriented in the shape of -14-201200092 which is recessed on the side opposite to the side connected to the separating portion, and the air on the outer side of the swirling flow of the separating portion is the inside of the filter flowing into the housing, and the air inside the swirling flow of the separating portion, It flows into the housing and is the outside of the filter. According to the first embodiment of the present invention, the separation portion and the accommodating portion are arranged and communicated in the axial direction, and then the air on the outer side of the swirling flow of the separation portion flows into the filter having the concave shape in the accommodating portion. The air inside the swirling flow of the separating portion flows into the accommodating portion and is provided outside the filter having a concave shape, so that the dust can be compressed without the trouble of the user's hand, and the user can easily discharge the accumulated dust. , can reduce the decrease in attractiveness. Further, the electric vacuum cleaner according to the first embodiment of the present invention includes the cleaner body 1 and the dust collecting device 2; the cleaner body 1 is an electric blower 28 including a main body intake port 21 and an attraction force, and the dust collecting device 28 The device 2 is detachably attached between the main body suction port 21 of the cleaner body and the electric blower 28, and is characterized in that the dust collecting device 2 is provided with a substantially cylindrical shape and can communicate with the main body suction port 21 The dust collecting portion (for example, the dust separating portion 4) and the second dust collecting portion (for example, the dust containing portion 5) that communicates with the end portion of the first dust collecting portion in the axial direction and communicates with the electric blower 28, the first dust collecting portion The inner tube 7 having a plurality of through holes 33 on the circumferential surface is enclosed in a substantially cylindrical shape, and the second dust collecting portion is opened toward the side communicating with the first dust collecting portion and has a direction The ventilation member (for example, the dust collecting case 12) having a shape recessed on the side opposite to the first dust collecting portion is wrapped therein, and the outer side of the inner tube 7 of the first dust collecting portion is connected to the second dust collecting portion. An opening having a venting member having a concave shape, and an inner tube 7 of the first dust collecting portion The inner side is connected to -15-201200092: the outer side of the ventilation member having the concave shape in the second dust collecting portion. According to the first embodiment of the present invention, the second dust collecting portion is communicated with the axial end portion of the first dust collecting portion, and then the outer side of the inner tube 7 of the first dust collecting portion is communicated with the second set. An opening having a concave-shaped ventilation member in the dust portion communicates the inside of the inner tube 7 of the first dust collecting portion with the outer side of the ventilation member having the concave shape in the second dust collecting portion, so that the user does not have to bother The hand can compress the dust, and the user can easily discharge the accumulated dust, and further, the decrease in the attraction force can be suppressed. Fig. 1 is a cross-sectional view showing the cleaner body 1 of the embodiment of the present invention as seen from the side. In the state of use of the vacuum cleaner, the vacuum cleaner body 1 is placed horizontally, and it is preferable that the vacuum cleaner body 1 is placed vertically in the storage state of the vacuum cleaner. In the state of use of the electric vacuum cleaner, when the main body intake port 21 side is the front (upstream side) and the main body exhaust port 30 side is the rear (downstream side), the electric vacuum cleaner is stored in the state, and the main body suction port is provided. 2 1 becomes the upper side in the direction of gravity action and the body exhaust port 30 becomes the lower side of the gravity action side. When the cleaner body 1 is placed horizontally, it is the lower surface of the cleaner body 1, and is parallel to the surface on which the cleaner body 1 is placed (e.g., the floor surface), and is perpendicular to the direction of gravity. First, the configuration of the cleaner body 1 will be described. The dust collecting device 2 for collecting dust from the inhaled air is detachably attached to the front side of the cleaner body 1. When the longitudinal direction (axial direction) of the dust collecting device 2 is used as the gravity acting direction (vertical arrangement), the height of the cleaner body 1 becomes higher. 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) is to the direction of gravity action, the separation effect produced by the centrifugal separation action becomes larger, When the axial direction of the swirling flow in the dust collecting device 2 is opposite to the direction of gravity action, if it exceeds 45 degrees, the separation effect by the centrifugal separation action is extremely lowered. Here, in order to suppress a decrease in the separation effect caused by the centrifugal separation when the height of the cleaner body 1 is reduced, in the present embodiment, the axial direction of the dust collecting device 2 is 40 degrees with respect to the direction of gravity action. About 45 degrees. However, in order to improve the separation effect by the centrifugal separation, the axial direction of the dust collecting device 2 can also be made smaller than 40 degrees with respect to the direction of gravity (for example, 0 degree). The dust separating portion (the turning portion) 4 is disposed on the lower side, and the dust containing portion 5 is disposed on the upper side, and instead, 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 swirls the sucked air and separates the dust by a centrifugal separation action (cyclone type), and communicates with the dust separating unit 4, and accommodates the separation by the dust separating unit 4. Dust dust accommodation section 5. The dust separating unit 4 and the dust accommodating portion 5 are arranged in the axial direction of the stacking device 2, and are connected and connected in the end portions of the respective axial directions. 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 front side of the cleaner body 1 with respect to the dust separating unit 4. The dust separating unit 4 and the dust containing unit 5 are connected together so that the user can easily separate the dust separating unit 4 and the dust containing 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 portion is connected to the inlet pipe 3. Here, the front end surface of the front portion in the axial direction of the portion 4 of the dust separating portion is 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 is connected to the inlet pipe 3. The inlet pipe 3 is preferably formed in the center of the cleaner body 1 in the width direction. The inner cylinder 7 and the recessed portion 8 are also preferably formed in the center of the cleaner body 1 in the width direction. The dust separating unit 4 is an inner cylinder 7 having a substantially cylindrical outer cylinder 6 and a hollow cylindrical outer 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 is displaced 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 in the axial direction 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. , for the opening. The outer tube 6 is preferably made of a transparent or translucent plastic or resin in order to allow the user to see the accumulation of dust or to detect the accumulation of dust on the sensor provided outside the outer tube 6. 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 with 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), one portion 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 depressed portions 8 -18 - 201200092 may also 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 "the axial direction of the depressed portion 8" may be substantially the entire length of the axial direction of the cylindrical portion of the inner cylinder 7. In this case, the opening which becomes the recessed portion 8 is formed over a part 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 1/2 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, and is formed to have a number of about 001 in the circumferential direction. 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 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 irregularities but by curved surfaces. Thereby, the pressure is continuously suppressed and the air is sufficiently swirled. It does not matter if the guide tube 3 8 ’ is not present. An extension portion 34 extending 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 that opens inside the inner cylinder 7. As shown in Fig. 3(A), a portion 'in 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 -19 - 201200092 (for example, silver, copper) or an antibacterial substance (for example, silver, copper) or a metal coated with the above substance in order to inhibit the growth of the bacteria. (for example: stainless steel) is better. However, the inner cylinder 7, which includes the rounded 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 circumference 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. Further, the outer cylinder 6 and the inner cylinder 7 are coupled so that the user can easily separate the outer cylinder 6 from the inner cylinder 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 this through hole 33, coarser garbage does not flow into the inner cylinder 7, and 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, but the garbage of the heavy il of 1 yen or more 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 spacer 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 of -20-201200092, 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 the outer flow path 35 5 that communicates with the front cover 1 1 as shown in Fig. 3 (A). The wall surface in the circumferential direction of the opening of a part of the upper side is higher in the circumferential direction on the side opposite to the opening of the guide tube 38, and the wall surface of the guide tube 38 in the circumferential direction is 1 = 1 When the dust separation portion 4 is viewed from the front, for example, when the opening direction of the guide tube 38 is counterclockwise, 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 The higher 'right side wall is lower. In other words, the portion of the upper side of the extension portion 34 is an opening, so that 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 swirling flow outside the inner cylinder 7 collides with the higher wall surface in the circumferential direction of the opening of the upper portion of the upper portion of the extension portion 34, which can be smoothly changed toward the axial direction, and the dust contained in the swirling flow becomes easy. The dust accommodation portion 5 flows toward the dust. On the other hand, the inner side of the inner cylinder 7 is an inner flow path 36 that communicates with the front cover 11. The dust accommodating portion 5 is provided with an outer casing 10 (the front end surface) and an axial end surface (the rear end surface) having an opening "and a hollow outer casing having a substantially inverted triangle shape. The direction of the end face 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 outer casing 1 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, 'the upper part of the front side of the casing 10 is provided with a button 17 (which can also be a control - 21 - 201200092) which the user can press, and a button 17 is connected to the front side of the casing 10 ) 18. 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 conveying rod is a claw that can be engaged with the upper end portion of the front cover 11. In a state where the front cover 11 is closed by the outer casing 1 , 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 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), and the card of the other end of the bar 18 and the claw of the upper end portion of the front cover U are transmitted. The assembly 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 10 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 1 by gravity. Further, as will be described later, the dust box (dust collecting container) 12 is spring-loaded so as to be ejected toward the front side of the casing 10 by a spring (elastic body), and the dust collecting box 12 presses the front cover 11 Later, 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 I2. In other words, the dust collecting case 12 is housed in the casing 10 by the pressing of the opening surface of the dust collecting case 12 by the rear surface of the front cover 11, and the storage state is maintained. The other end surface of the outer casing 10 in the axial direction is closed by the filter 15 that can be opened and closed. The lower end portion of the filter 15 is provided with a shaft 3 2 which is supported by the lower end portion of the outer casing 10. The filter 15 is pivoted forward and backward toward the axial direction of the casing 10 with the shaft 32 as a fulcrum. The filter 15 has 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-density EPA filter (High Efficiency Particulate Air Filter). The so-called HEPA filter is for particle size 0 at rated air volume. 3 // m of particles have 99. The particle collection rate of 97% 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 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 opposite side to the opening. The cross-sectional shape of the dust collecting box 12 may be substantially quadrangular, 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 collecting case 12 but also the air permeability of the upper, lower, left and right sides of the -23-201200092, even if dust accumulates on the bottom surface of the dust collecting case 12, the flow path can be ensured, and the pressure loss of the intake air can be reduced, thereby suppressing Reduced attraction. 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 10 in the axial direction. That is, the opening direction of the dust collecting case 12 is the same as the opening direction of the one end surface in the axial direction of the outer casing 10. 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 10 in the axial direction, and the outer peripheral end of the opening face of the dust collecting case 12 The lower side is about half, and 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 dust collecting box 12 is pivoted toward the axial direction of the casing 10 with the shaft 14 of the lower portion as a fulcrum. Thereby, when the front cover 11 is opened from the dust accommodating portion 5, a part of the dust box 12 can be ejected from the dust accommodating portion 5 by gravity. Since the position at which the shaft 14 of the outer casing 10 is formed is the same side (lower side) as the position at which the shaft 31 of the outer casing 1 is formed, when the front cover 1 is opened from the dust containing portion 5, there is no A part of the dust box 12 can be ejected from the dust containing portion 5 due to the hindrance of the front cover 11. 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, so that the user can easily discharge it from -24 to 201200092. The dust accumulated in the dust box 12. Further, the dust box 12 is preferably divided into upper and lower sides, that is, a so-called two structures of a frame (bracket) of the upper half and a 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(A), 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 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 inside 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 10 is inclined by 40° to 45° with respect to the direction of gravity, the dust collecting box I2 is ejected from the dust receiving portion 5 by 30°, so that it can be accumulated in the dust collecting box 1 2 . The dust inside is discharged toward the direction of gravity. In the front cover 11, a front side flow path 35 and an inner side flow path 36 are formed to penetrate in the axial direction. On the other hand, the outer flow path 35 is formed between the outer side flow path 35 of the front cover 1 and the inner side flow path 35, and is connected to the dust separation unit 4, particularly between 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 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 the opening of the dust collecting box 12 Half of the upper side or upper end is better. 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 vacuum cleaner is stopped, in order to prevent the dust accumulated in the dust collection -25 - 201200092 box 12 from flowing back to the inside of the outer flow path 35 and the dust separation portion 4 'in the outer flow path 35 or the other end portion' It is preferable to form a check valve (not shown) that covers the outer flow path 35. The check valve ' is rotated toward the dust box 12 by the upper end as a fulcrum. However, the 'check valve is not a necessary 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 1 1 toward the center side. That is, 'from the outer side of the dust box 12 toward the center side. In order to suppress the disturbance of the air flowing in from the outer flow path 35 toward the dust box 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 box 1 communicates. The direction is better. 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 channel 36 is connected to the outer casing, in particular, the outer side of the dust 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 the one end toward the other end of the inner flow path 36 to the outer side of the upper portion of the dust containing portion 5, and is provided to extend in the horizontal direction. The handle 16 that can be held. When the user holds the handle 16, the dust accommodation portion 5 is lifted upward, and the dust separation portion 4 is left in the cleaner body 1, and only the dust accommodation portion 5 can be removed from the cleaner body 1. When the dust separating unit 4 and the dust accommodating portion 5 are connected, the user can lift the dust accommodating portion 5 upward by holding the handle 16, and -26-201200092 can be integrated as the dust separating portion 4 and In the dust accommodating portion 5, the dust collecting device 2 is also detached from the cleaner body 1. As shown in Fig. 1, the direction in which the other end surface (corresponding to the portion of the superconductor 15) in the axial direction of the 麈 容 纳 纳 5 is inclined toward the outer casing 10 side from the vertical surface (gravity action direction). That is, it is preferable that the lower portion of the other end surface 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 in which the one end surface (corresponding to the front cover portion) in the axial direction of the dust accommodation portion 5 is inclined by 40 degrees toward the outer casing 10 side than the vertical surface (gravity action direction). About 45 degrees. That is, the lower portion of the upper end than the one end surface of the dust accommodation portion 5 is closer to the outer side of the casing i. Thereby, the one end surface in the axial direction and the other end surface in the axial direction of the dust accommodating portion 5 are inverted octagon type based on the vertical surface (the direction of gravity action). 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. On the other hand, the user removes the dust accommodating portion 5 and then holds the recessed portion 3 9 toward the upper side of the dust separating portion 4 or lifts it obliquely upward, whereby the dust separating portion 4 can be easily removed from the cleaner body 1. As shown in Fig. 1, the direction in which the axial direction of the dust separating portion 4 is formed (corresponding to the portion of the inlet pipe 3) is preferably inclined 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 axial direction of the dust separating portion 4. Therefore, 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 cleaner body 4, the dust separating unit 4 and the dust containing unit 5 are integrated as a whole -27-201200092, that is, when the dust collecting device 2 is unloaded from the cleaner body 1 Since the one end surface of the dust collecting device 2 and the other end surface in the axial direction are in the inverted figure shape based on the vertical surface (gravity action direction), the dust collecting device 2 is not lifted when it is lifted upward, and is used. The dust collecting device 2 can be easily removed 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. On the rear upper side in the cleaner body 1, there is provided an opening of the intake duct 27 and the one end of the intake duct 27 extending in the front-rear direction of the cleaner body 1 so as to face 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 of the suction duct 27 is disposed in the vicinity of the other end, that is, the side of the electric blower 28 is open at one end of the suction duct 27 of the cleaner body 1. The upper portion of the opening 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. 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 fold of the filter 〖5 is the longitudinal direction, the dust that is shaken off becomes easy to fall toward the direction of gravity. The dust -28 - 201200092 which is 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. On the downstream side of the electric blower 28 and on the front side of the electric blower 28, an exhaust duct 40 that communicates with the exhaust port of the electric blower 28 is provided. Further, on the downstream side of the exhaust duct 40 and at the front side of the exhaust duct 4, a filter 29 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 is, for example, a high density ULPA filter (Ultra Low Penetration Air Filter). U LP A filter for particle size at rated air volume. 1 5 μ m particles, with 99. The particle collection rate of 9995 % or more is an air filter having 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 center of the outer cylinder 6 of the air is -29 - 201200092 and is rotated around 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 is concentrated outside 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, it is possible to maintain a lot of dust without bothering 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 33 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 dust and 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. 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. 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 collecting box 12 partitions (separates) 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 -30-201200092 28 is passed through the exhaust duct 4 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 same or higher dust collecting efficiency as 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. Fig. 2 is a perspective view showing a dust collecting device 2 according to an embodiment of the present invention, and Fig. 2 is a cross-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 concentrating device 2 upward. However, it is also possible to leave the dust separating unit 4 in the cleaner body 1' and only remove the 容纳 accommodating portion 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 is substantially quadrangular after the portion of the front cover 11, 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 axial direction of the outer casing 1〇 are not in a straight line, and are different by about 45 to 5 degrees. That is, the axial direction of the dust accommodating portion 5 is curved at a slightly front side than the middle. As described above, the one end surface of the dust collecting device 2 (the portion of the inlet pipe 3) is slightly oriented toward the lower side (the direction of gravity action), and the other end face of the dust collecting device 2 in the axial direction (the portion of the filter 15) ), also slightly -31 - 201200092 The direction of the micro direction toward the lower side (the direction of gravity action) is due to 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. Since the dust 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 portion where the inlet pipe 3 is formed, 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 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 cylindrical portion of the inner cylinder 7 in the axial direction from the outer cylinder 6. 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 is provided with 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 extending portion 34 facing the opening direction of the guide tube 38 is higher than the other wall surface (right wall surface). Further, 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. As shown in Fig. 3(B), the substantially semicircular portion on the upper side in the inner cylinder 7 is provided with a substantially semicircular portion on the lower side of the recessed portion 39' that is recessed toward the inner side of the inner cylinder 7 from -32 to 201200092. The inner cylinder 7 is open. 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 3 4 . The area where the recessed portion 39 can be made more toward the opening in the inner cylinder 7 can be made more toward the open area in the inner cylinder 7 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 recessed portion 3-9. When the cylindrical portion of the inner cylinder 7 is formed of a metal material having an antibacterial effect, firstly, it is a thin metal plate having a diameter of 〇·1 mm~0. A plurality of through holes 3 3 of about 4 mm are etched and processed, and then the ends are joined to form a cylindrical shape. The through hole 33 can also be punched. The metal material as an antibacterial effect is, for example, stainless steel, silver, copper or the like. It is not limited to stainless steel, silver, or copper, and may be an alloy containing silver or copper or a surface of silver or copper. The thickness of the metal thin plate is 1 mm or less 'in order to improve the workability'. 1mm~0. About 5mm is better. When the thickness of the thin metal plate is thin, in order to increase the strength or 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 the shape of 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 A cylindrical metal sheet is provided 'subsequent' by insert molding into the mold by pouring the resin into the mold. In the case of insert molding, it is not necessary to join both ends of the thin metal plate to form a cylindrical shape. Thus, the one end portion of the substantially circular 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 portion 34 having the annular shape of -33 to 201200092 can be made of resin. Only the cylindrical portion of the inner cylinder 7 is made of a metal material. The manufacturing process is 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 view showing dust according to an embodiment of the present invention. A perspective view of a state in which the rear filter of the housing portion 5 is opened. As shown in Fig. 4(A), when the front cover 1 1 is pivotally opened in the downward direction with the shaft 3 1 as a fulcrum, the dust box 12 is also swung in the lower direction with the shaft 14 as a fulcrum. At this time, the dust collecting box 12 is divided into upper and lower sides by the shaft 1 3 as the fulcrum, and the opening of the dust collecting box 12 when being ejected from the dust containing portion 5 is compared with the set when it is housed in the dust containing portion 5. The opening of the dust box 12 is expanded. Thereby, the dust adhering to the inner surface of the dust box 12 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 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 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. 5 - 34 - 201200092 The substantially circular portion on the outer side of the hatched portion shown in Fig. (A) is an outer peripheral end which 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, 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 side flow path 35 (outside the dust accommodation part 5) may be on the left side or the lower side of the front cover 1 1 , but on the back side of the outer flow path 35 (dust accommodation part 5) When the opening position of the inner side is made 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 in the front cover 1 The upper side is better. 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 the depressed 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 passage 36 is smaller than the opening area of the outer flow passage 35 as the substantial flow passage area. . 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 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 12. 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 vacuum cleaner is stopped, the dust-35-201200092 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 at the central portion including the center line of the front cover 1 1 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 box 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 11. 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 hatched portion on the upper side of the opening of the inner side flow path 36 is a lower end that abuts against the outer peripheral end of the opening of the dust collecting case 12. 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 side 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 Fig. 5 (A) and Fig. 5 (B), the opening area (Fig. 5 (B)) of the other end (back side) of the inner channel 36 is a ratio of the inner channel. The opening area (Fig. 5(A)) of one end (surface side) of 36 is still 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 of -36-201200092, the outer end of the opening of the outer end of the outer casing 10 in the axial direction abuts against a part of the outer peripheral end of the opening of the dust collecting case 12. Further, it is shown that 8 〇% 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 casing 12. On the other hand, the area other than the dust collecting box of the opening of the outer casing 10 (about 20% or less left) is opposed to the inner flow port and communicates with the inner flow path 36. Fig. 7 is a view showing an electric vacuum cleaner of an electric vacuum cleaner according to an embodiment of the present invention. In addition to the cleaner body 1, there is provided a 50, a joint pipe (extension pipe) 51, an operation pipe 52, and the suction device 50.

The body suction port 21 of the suction body 1 can be inserted into and held by the tube 20. Further, on both sides of the cleaner body 1 When the electric power is turned ON by the operation of the operation button/switch from the user, the electric blower 28 operates to generate the suction air of the suction inlet 50, and sequentially passes through the joint pipe 51, the hose. 54. The hose joint pipe 20 flows into the cleaner body 1. Fig. 8 is a view showing a vacuum cleaner body 1 in the vicinity of the center of the upper surface of the cleaner body 1 according to the embodiment of the present invention, and is provided with a vacuum cleaner The dust collecting damper cover 56 supported by the shaft in the manner of the rotation of the body 1 is at the rear end of the cover 56 on the upper surface of the cleaner body 1, as shown in Fig. 6, which is the opening path of the dust collecting unit 1 Open the view: Inhalation hose 54; Tube) 51, for tube 5 2, the end of the user's grip is the connector tube 20 hose connector 5 5. However, the vacuum cleaner is used. From the suction operation tube 52 perspective view. The one end is provided at the side where I is used for 2, and -37-201200092 is provided with a handle 37 for lifting the cleaner body 1 by a user who is supported by the shaft so as to be rotatable toward the cleaner body 1. According to the embodiment of the present invention, the dust can be compressed without the trouble of the user's hand, and the user can easily discharge the compressed accumulated dust, and further, the decrease in the attractive force can be suppressed. The upper cover 5 6 is preferably formed to cover the size of the handle 16 of the dust collecting device 2 in the closed state and to be formed at the equivalent position. Further, the upper shroud 56 is locked so that it cannot be opened during the operation of the cleaner body 1, or the operation of the vacuum cleaner body 1 is preferably stopped when the upper shroud 1 is opened. By the upper shroud 56, it is possible to prevent the user from removing the dust collecting device 2 during the operation of the cleaner body 1, thereby improving the safety of the electric vacuum cleaner. [Embodiment 2] The details of the inner cylinder 7 of the first embodiment will be described as a second embodiment. An electric vacuum cleaner according to a second embodiment of the present invention is characterized in that the dust collecting device 2 is internally wrapped with an inner cylinder 7 having a plurality of through holes 33 on its circumferential surface, and one end of the inner cylinder 7 in the axial direction is closed. The other end of the inner cylinder 7 in the axial direction is open and communicates toward the electric blower 28 side, and one end of the inner cylinder 7 in the axial direction is formed at a position facing the outlet side opening of the inlet pipe 3 of the dust collecting device 2. On the other hand, one end of the inner cylinder 7 in the axial direction is formed such that the air sucked from the inlet pipe 3 of the dust collecting device 2 is swirled in the circumferential direction. Further, the vacuum cleaner according to the second embodiment of the present invention is characterized in that the closing portion of the inner tube 7 at one end in the axial direction is provided to hold the inlet pipe 3 of the dust device 2 from the set -38-201200092. The shape of the air swirls toward the circumferential direction. Further, in the electric vacuum cleaner according to the second embodiment of the present invention, the closed portion of the inner cylinder 7 at one end in the axial direction is provided with a shape that is recessed toward the inner side in the axial direction of the inner cylinder 7 (for example, a depressed portion) 8) One of the shapes of the recesses is a mouth opening toward the circumferential surface of the inner cylinder 7. Further, according to the second embodiment of the present invention, by making the end of the inner cylinder 7 have a swirling function, the length of the dust collecting device 2 in the axial direction can be shortened without increasing the width, and the electric vacuum cleaner can be made 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 5 8 ' is located on the bottom side of the cylindrical portion of the inner cylinder 7. The base of the trapezoidal conical portion 580 is joined to the inner peripheral end of the extension portion 34. By the trapezoidal conical portion 5, the joint portion between the cylindrical portion 57 and the extension portion 34 becomes gentler, the generation of peeling or turbulent flow of the air flow can be suppressed, and the energy loss of the intake air can be reduced, and the 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 constituted only by 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 -39-201200092 outer shape radius of the trapezoidal conical portion 58, and R3 is the outer shape radius of the outer portion 34'. 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) 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 that is connected to the opening of the recessed portion 8, and the other end is oriented toward the outer side of the cylindrical portion 57 at the outer side of the cylindrical portion 57 (along the trapezoidal conical portion 5 8) In the direction of the outer circumference, it is gently bent in a substantially semicircular shape by turning it to 180°. 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 from the side of the recessed portion 8 to the joint portion of the guide tube 38, and it is preferable to form the flat portion without the step difference. . Thereby, the energy loss of the intake air can be reduced, and the noise can be suppressed. The thickness 〇 1 of the cylindrical portion 579 (between the outer shape R 1 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 579 is formed to be -40-201200092 to deflect the air flow to the inner wall of the flow path of approximately 180 degrees, so that it is thicker to reduce noise. Here, the thickness D of the cylindrical portion 57 is about 13 mm. 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 (into the inside of the inlet opening) of the inlet pipe 3. When the radius of the depressed 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 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 pipe 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 the one end of the cylindrical portion 57, a sufficient swirling force can be imparted to the sucked air. An end opening (an opening of the upper portion of the extension portion 34) of the outer flow path 35 is formed at a side opposite to the circumferential direction of the guide tube -41 - 201200092 in the circumferential direction (the opposite side of the 180 degrees). The through hole 33 may be formed between at least one end of the guide tube end portion 59 to the outer side flow path 35. Since the dust is easily flowed in the outer flow path 35, the length in the circumferential direction of the opening of one end of the outer flow path 35 is preferably longer. The downstream side wall surface 65 (left wall surface) of one end of the outer flow path 35 is higher than the upstream side wall surface 6 6 (right wall surface), and the downstream side wall surface 65 is from the inner peripheral side toward the outer peripheral side when viewed from the axial direction. The outer peripheral side is inclined toward the upstream side wall surface 6 and longer in the circumferential direction than the inner peripheral side. When the garbage card having a length such as hair or cotton wadding is attached to the downstream side wall surface 65, the force of guiding the garbage toward the inner peripheral side is effective 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 the position on the left side in the ninth drawing. Fig. 1 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 10 shows the direction of flow of the inhaled air. The air that flows in the substantially axial direction in the recessed portion 8 is turned in the radial direction by the recessed portion 8, and is turned toward the circumferential direction by the guide tube 38, and is about half a week between the inner cylinder 7 and the outer cylinder 6 (that is, guided from the guide). The pipe end portion 5 9 to -42 · 201200092 one end of the outer flow path 35 is open to flow in the circumferential direction and the axial direction (swing), and most of the inflowing air is open to the one end of the outer flow path 35 (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 that flows (rotates) in the circumferential direction and the axial direction about halfway 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 3 3 flows into the inner cylinder 7 (airflow 6 3 ). Further, the air that does not flow to the one end of the outer flow path 35 is oriented in the circumferential direction about half a week 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 59). The flow (flow 64) merges with the air exiting the guide tube 38. In the second embodiment of the present invention, the air swirled on the outer side of the inner cylinder 7 flows into the dust accommodation portion 5 that communicates with the electric blower 28 through the outer flow passage 35, and it is not necessary to increase the centrifugal separation distance as long as half a week or so. can. Therefore, the height of the inner cylinder 7 and the axial length of the dust separating portion 4 can be shortened, and the length of the dust collecting device 2 in the axial direction can be shortened, and 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 of the dust separating portion 4 (excluding the inlet pipe 3) is approximately equivalent 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 6 2 ) flowing into the one end of the outer flow path 35 as the flow rate V 1, and the flow rate of the air (the air flow 63) flowing into the inner tube 7 from the through hole 33 is the flow rate V2, and there is no flow into the outer flow. The flow rate of the air (air flow 64) opened at one end of the road -43-201200092 35 is "having a relationship of V1 > V2 > V3" as the flow rate 乂3, and 'the flow rate at the inlet pipe 3' is compared with the flow rate at the inlet pipe 3 The flow rate is higher, and the flow rate at the outer flow path 35 is higher than the flow rate at the guide tube 38. That is, the air flow 6 2 ' is accelerated at the guide tube 38 and 'accelerated at the outer flow path' is divided into two stages of acceleration. Therefore, the flow path cross section of the guide pipe 38 is smaller than the flow path cross section of the inlet pipe 3, and the flow path cross section of the outer flow path 35 is smaller than that of the flow path cross section of the guide pipe 38. The width W of the flow path in the radial direction is widened with respect to the width W1 of the flow path at the end portion of the guide tube end portion 59 of the guide tube 38, and the width W2 of the flow path at the position from the guide tube 38 is expanded. The outlet of the guide pipe end portion 59 is fixed until the one end of the outer flow path 35 is opened (flow path width W2)', and is gradually moved from one end of the outer flow path 35 to the guide pipe end portion 59. The flow path width W2 to the flow path width W3 is narrowed, and the guide tube end portion 59 becomes the flow path width W3. Thus, there is a relationship of W2 > W1 > W3. If W3 is too small, the dust will be clogged, so for example, W 3 is about 1.0 cm. For example, \¥2 is 113-111 and is 4 (^). \¥1 is 2-2-¥3- (the thickness in the radial direction of the guide tube end portion 59) and is slightly smaller than 3 cm. The perspective view of the inner tube 7 of the second embodiment of the present invention is seen from the side of the cylindrical portion. The side wall of the guide tube end portion 59 is not terminated perpendicularly to the circumferential direction, but is roughly divided into two stages of buckling. Specifically, the end of the bow end portion of the bow end portion 59 from the axial direction to the intermediate portion in the axial direction is an end point close to a perpendicular line perpendicular to the circumferential direction, and is terminated to the end portion of the guide tube. The guide tube end portion 59 has a terminal end in the axial direction from the bottom of the axial direction, which is inclined more obliquely than the perpendicular line perpendicular to the circumferential direction. For example, -44-201200092, 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 root portion 60 of the guide pipe end portion 59, a sufficient swirling force cannot be provided and the separation cannot be sufficiently performed. dust. 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 flow is excessively strong. In other words, dust is not absorbed by the outer flow path 35 (especially dust having a large specific gravity), and dust may remain in the dust separating unit 4. In particular, in the present invention, since the inlet side of the dust separating unit 4 is located in the direction of gravity and the outlet side is located in the direction of gravity, the dust cannot be sucked by the outer flow path 35, so that dust remains in the dust separating unit 4. Significant. 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). In this case, the axial direction of the distal end side of the guide tube end portion 59 in the axial direction is made longer in the circumferential direction, whereby the axial direction bottom side of the guide tube end portion 59 having a large flow rate can be given. 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 in one step from the distal end side in the axial direction toward the bottom side in the axial direction. Fig. 12 is a plan view of the inner tube 7 of the second embodiment of the present invention as seen from the back side of the extension portion. 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 gasket 9 (sealing member) is attached to the back side of the extension portion 34 by three screws 6 7 (mounting members) by -45-201200092. 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 on the outer side flow path 35, and the lip portion 169 is for maintaining the inner tube 7 and the front cover located inside the inner flow path 36. Set 1 1 for air tightness. 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 11 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, the dust from the outer flow path 35 or the leakage may be caught. By forming the lip portion 69 from the outer peripheral side toward the inner peripheral side, it is possible to suppress the cock from being stuck 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 recessed toward the inner side in the axial direction of the cylindrical portion, the cylindrical portion The substantially lower half of the inner peripheral side (the inner peripheral side of the lip portion 69) is opened without being closed by the spacer 9. The opening, -46-201200092, forms an inner flow path 36. The spacer 9 may be the same as the area of the opening portion of the closed portion, and may be 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 wall surface 65, and the dust contained in the swirling flow also becomes easy to flow toward the dust containing portion 5. The inner wall surface 110 of the outer flow path 35 is the other end surface in the axial direction of the inner tube 7 from the downstream side wall surface 65 of the inlet of the outer flow path 35 toward the outlet of the outer flow path 35, and is oriented in the circumferential direction. It is formed obliquely or curved. Thereby, the dust can smoothly flow in the outer flow path 35. Further, since the inner wall surface 110 of the outer channel 35 is inclined or curved, the air flow from the outer channel 35 is not only a component in the axial direction but also a component in the circumferential direction (cycloid component). . Fig. 15 is a side elevational view of the inner cylinder 7 of the second embodiment of the present invention as seen from the right side. The extension portion 34 has a lower height in the axial direction toward the outer flow path 35 (from the lower side toward the upper side). The surface of the extension portion 34 is formed in a spiral shape toward the outer flow path 35 on the first circumference. When the height of the cylindrical portion 57 is taken as Η 1 and the height at the highest position of the trapezoidal conical portion 58 is Η 2, the relationship of Η 1 > Η 2 is obtained. Further, when the height at the highest position of the guide tube 38 is Η3, the relationship of Η3>Η1 is obtained. The through hole 33 is formed so as to be formed between the end of the at least one of the guide tube end portions 59 and the outer flow path 35, that is, -47-201200092, and the inner side of the outer flow path 35 can be formed at the end of the guide tube. The side of the part 59 can be used. On the side of the outer flow path 35, since the flow rate into the outer flow path 35 is larger than the flow rate of the inflow through hole 33, it is meaningless to form the through hole 33 on the side of the outer flow path 35. A cross-sectional view of the inner cylinder 7 of the second embodiment of the present invention is seen from the right side. If the depth of the deepest portion in the axial direction of the depressed portion 8 is H4, it has Η 4 < Η 1 relationship. That is, the depth of the depressed portion 8 is shallower than the height of the cylindrical portion 57. The concave portion 8 is hemispherical from a three-dimensional perspective, and the sectional shape of the depressed portion 8 is substantially semicircular as shown in Fig. 14. Therefore, the depth Η4 of the depressed portion 8 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 position in which the recessed portion 8 is formed in the axial direction is a position where it is formed in the axial direction of the through hole 33. If the depth Η4 of the recessed portion 8 is too deep, the flow rate of the air taken in from the through hole 33 is reduced. On the other hand, if the depth Η4 of the recessed portion 8 is too shallow, there is dust clogging in the recessed portion 8. . The ease of injection molding is also considered, and the depressed portion 8 is preferably formed into a hemispherical shape. However, the depressed portion 8 is not limited to a hemispherical shape, and may be an elliptical or deep elliptical shape that is shallower than a hemispherical shape. On the other hand, at one end of the bottom surface of the guide tube 38, the bottom surface of the recessed portion 8 is smoothly joined without a step difference, and the other end of the bottom surface of the guide tube 38 is smoothly joined to the surface of the extension portion 34 without a step difference, and the guide tube 38 is guided. The bottom surface 'is preferably gentlely inclined without a step difference from one end of the bottom surface of the guide tube 38 to the other end of the bottom surface of the guide tube 38. Further, since the guide tube 38 is provided in one half of the hemispherical recessed portion 8, when the guide tube 38 is removed, the recessed portion 8 is actually W4 spherical. • 48 - 201200092, the air swirling on the outside of the cylindrical portion is discharged from the outer flow path 35 (air flow 6 2 ). The air which flows into the inside of the cylindrical portion from the through hole 3 3 is discharged from the inner flow path 36 while being swirled in a small space in the space in the cylindrical portion and the space in the extension portion 34 (air flow 63). The air that has flowed from the through hole 33 to the inside of the cylindrical portion has a relatively large energy loss compared to the air swirled on the outer side of the cylindrical portion. However, the dust does not accumulate in the dust containing portion 5, and the through hole 3 is not provided. 3 The flow rate of the air flowing into the inside of the cylindrical portion is relatively small compared to the flow rate of the air swirling on the outer side of the cylindrical portion, so that the energy loss as a whole is small. Fig. 17(a) is a perspective view of the dust separating portion of the second 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 second embodiment of the present invention as viewed from the right side. Figure. The arrow in Fig. 17 shows 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 is abutted against the outlet end of the inlet pipe 3. In view of the problem of the combination accuracy, the axial end portion of the cylindrical portion 57 and the outlet end portion of the inlet pipe 3 are not completely abutted, and even if there is a small gap (1 mm or less), it does not matter. However, if there is a gap, the air will leak, the energy loss will increase, and the noise will become larger. Therefore, when the axial end portion of the cylindrical portion 57 and the outlet end portion of the inlet pipe 3 are made airtight, the front end portion of the gasket (sealing member) in the axial direction of the cylindrical portion 57 and the outlet of the inlet pipe 3 may be provided. On the other hand, as shown in the enlarged cross-sectional view, the inner side of the axial end surface of the outer cylinder 7 and the full length of the front end portion of the guide tube 38 in the axial direction are guided along -49-201200092 The front end portion of the tube 38 in the axial direction forms a step difference. When the thickness of the end surface of the outer tube 7 in the axial direction is D2, and the thickness of the inner peripheral side of the portion of the end portion of the guide tube 38 corresponding to the end surface of the outer tube 7 in the axial direction is D3, D 2 >; D 3 relationship, thus producing a phase difference of (D 3 - D 2 ). For example, 'D2 is about 3mm, and D3 is about 2mm. Therefore, the stage difference is about 1 mm. Therefore, the inner side of the axial end surface of the outer cylinder 7 is thinner on the inner peripheral side than the portion corresponding to the front end portion of the guide tube 38 in the axial direction. As shown in the enlarged cross-sectional view, the inner tube 6 and the outer tube 7 are combined so that the distal end portion of the guide tube 38 in the axial direction abuts against the difference in the stage. This stage difference has a sealing function between the inner side of the axial end surface of the outer cylinder 7 and the axial end portion of the guide tube 38. Therefore, the energy loss of the air can be reduced or the noise can be reduced by the difference in the stage. The machining accuracy or the combination accuracy is poor, or the electric blower 28 is operated, so that the inner cylinder 7 is suctioned toward the dust accommodation portion 5 side, and the axial end portion of the guide tube 38 does not completely abut the axial direction of the outer cylinder 6. At the inner side of the end face, the stage difference also suppresses air leakage. The thickness of the tip end portion of the guide tube 38 in the axial direction is thinner than the thickness D1 of the tip end portion of the cylindrical portion 57 in the axial direction. Therefore, it is difficult to form a sealing member such as a gasket, so that the sealing is achieved by the step difference. The function is better. Further, it is preferable that the inlet pipe 3 is integrally formed with the outer cylinder 6. The inner circumferential surface (side wall surface) of the outer cylinder 7 is close to the axial end surface (upper surface) of the outer cylinder 7, and is open from the outlet opening of the guide tube 38 to the inlet opening of the outer flow passage 35. Between the formation of the rectifying plate 102 (ribs, wings). The rectifying plate 102 may be formed at a position from the outlet opening of the guide tube 38 to the center of the inlet opening of the outer flow path 35, or may be 50-201200092 as the outlet opening of the guide tube 38 from the center. side. The rectifying plate 102 is a plate shape and is formed to extend in the circumferential direction. The length 'the circumferential direction of the flow regulating plate' is much smaller than the distance from the outlet opening of the guide pipe 38 to the inlet opening of the outer flow path 35. The direction in which the rectifying plate 1 〇 2 is formed as shown in Fig. 17 (b) is the direction from the formation position of the rectifying plate 102 toward the inlet opening of the outer flow path 35. The rectifying plate 102 can be one piece or a plurality of pieces. There is a large gap between the rectifying plate 102 and the extension portion 34, and of course there is air flow in the large gap. There is also a small gap between the rectifying plate 1 〇 2 and the inner side of the axial end surface of the outer cylinder 7, and the large slit also has air flow. A relatively small gap is formed between the inner side of the end surface of the rectifying plate 102 and the outer tube 7 in the axial direction. Since a flow is formed on both sides of the rectifying plate 102 by forming an air flow, the rectifying plate 102 can be suppressed. The turbulent flow of the downstream end. By this rectifying plate 102, the swirling flow can be directed toward the inlet opening of the outer flow path 35. Therefore, the air that has flowed in from the guide pipe 38 is guided toward the outer flow path 35 without being rotated around the outer cylinder 7 for several weeks, so that the energy loss of the air can be reduced. Further, the inner peripheral side (the outer peripheral surface of the inner cylinder 7) having a relatively slow flow rate is formed on the outer peripheral side (the inner peripheral surface of the outer cylinder 6) having a relatively high flow velocity, so that the shape of the rectifying plate 1 〇 2 is small. There is also the effect of turning the swirling flow. Since the flow plate 10 2 ' can be reduced, the turbulence of the air flow can be reduced to reduce the energy loss of the air. According to the second embodiment of the present invention, by forming the recessed portion 8 at the front end portion of the inner cylinder 7 to have a swirling function, the length of the dust collecting device 2 in the axial direction can be shortened, and the cleaner body 1 can be made smaller.

Figure 19, A perspective view of the cleaner body 1 of Embodiment 3-54-201200092 of the present invention is viewed from the upper right side. especially, The user is shown that the upper guard 56 is opened. The dust separating unit 4 is left in the cleaner body 1 and only the dust receiving unit 5 is pulled out in the substantially upward direction. 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 cleaner body 1 is placed (for example: Floor surface) is the direction of the vertical direction or the front side of the vertical direction (for example: 5 degrees) one end of the inlet pipe 3 of the dust separating portion 4 in the axial direction is a lower portion that abuts against 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), Fixed to the vacuum cleaner body! . The engagement mechanism is realized by the lower portion of the other end of the dust separating portion 4 in the axial direction and the engaging member 71. Therefore, the dust separating portion 4' is fixed to the cleaner body 1 as long as the user does not operate the engaging member 71'. Another aspect, The dust accommodating portion 5 is attached to the state of the cleaner body, 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, The upper surface of the dust accommodating portion 5 is abutted on the upper surface of the dust accommodating portion 5 by the nip gasket 25, and the other portion of the dust accommodating portion 5 is covered by the upper hood 56, It is not in contact with the dust separating portion 4 or the sucker body 1. That is, the dust receiving portion 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 can be detached from the cleaner body 1 independently from the dust-55-201200092 angstrom separating portion 4. therefore, For the user, The removal of the dust receiving 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, 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, The dust accommodating portion 5 can be pulled out 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 projection member 70 for guiding or assisting the attachment and detachment of the dust containing 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 7〇, Same material as the front cover 1 It is preferably formed integrally with the front cover 1 1 . It is not possible to form it in one piece. The front end of the protruding member 70 -56-201200092, To face the substantially pulled-out direction, 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 direction that is substantially perpendicular or a direction that is slightly forward than the vertical direction (for example: A predetermined angle within a range of 0 to 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 mounts the dust accommodating portion 5 to the cleaner body 1, First, the handle 16 of the dust receiving portion 5 is held, The front end surface of the protruding member 70 abuts against 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 it can't be pressed in with normal force, Close 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. Especially the display from the vacuum cleaner body! After the dust accommodation portion 5 is removed, The dust separating unit 4 is pulled out in a 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 is relative 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. The engaging member 7 1 ' is plate-shaped. The rear side is supported by the vacuum cleaner body 1 by the shaft. Furthermore, The spring is attached to the periphery of the shaft or to the engaging member 71 itself in such a manner that the front side of the engaging member 71 is urged toward the side of the cleaner body 1. In a state in which the dust separating portion 4 is installed, The axial direction of the dust separating portion 4 -57 - 201200092 The lower portion of the other end 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, Hold the inside or the outside of the recessed portion 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, user, The dust separating portion 4 can be easily removed from the sucker body 1. When the dust separating unit 4 is attached to the cleaner body 1, user, Hold 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 end of one end of the dust separating portion 4 in the axial direction, and the engagement is achieved. The dust separating unit 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 of the dust accommodation portion 5 in the axial direction is formed almost across the front side. However, as seen from the front side of the cleaner body 1, Then, the inlet opening (auxiliary filter 26)' of the suction duct 27 is formed close to the left side. also, The rear side wall surface ' of the sucker body 1 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 (engaging member) for engaging the inner end of the dust separating portion 4 in the axial direction -58 - 201200092 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 force, the dust accommodation portion 5 is intended to be displaced toward the rear side. Furthermore, 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 by the suction force. the result, The dust separating unit 4 will want to be from the cleaner body! Float. that is, The other end of the dust separating portion 4 in the axial direction, Because the engaged member 71 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, the one end of the dust separating portion 4 in the axial direction, Since the one end of the inlet pipe 3 in the axial direction abuts against the gasket 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, By the protruding member 7 2, 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, The filter 15 is rotatable relative to the outer casing 10. 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, It is disposed closer to the outer side of the outer casing 1 than the filter 15. 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. 22-59-201200092, 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 in which the rear end surface of the spacer 25 is formed when viewed from the side as shown in Fig. 22, The vertical angle with respect to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed is inclined at an angle b. 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 15 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, For the front side (the side of the outer casing 10). When viewed from the side as shown in Figure 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, It is located at the front side of the lower end of the rear end surface of the filter 15. E.g, Angle b, It is a predetermined angle in the range of 5 degrees to 10 degrees. and also, The rear side wall of the cleaner body 1, The wall surface facing the spacer 25 is formed at the front side of the wall surface opposite to the filter 15. Furthermore, Relative to the position of the filter 15, Compared to the position of the spacer 25, The position ' with respect to the wall surface of the cleaner body 1 facing the wall surface of the filter 15 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 25' between the dust containing portion 5 and the cleaner body 1 is preferably made of a material having a low viscosity from -60 to 201200092. 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 viscousness of the spacer 25 low, the attachment and detachment of the dust accommodating portion 5 from the cleaner body 1 becomes easy. 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' 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 dust receiving portion 5, The so-called other effect of maintaining the airtightness between the dust separating portion 4 and the dust accommodating portion 5 which are relatively easy to separate, the direction of the front end surface of the protruding member 70 when viewed from the side as shown in Fig. 22, It is inclined at an angle C 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. Relative to the position of the upper end of the front end -61 - 201200092 of the protruding member 7〇, The position ' of the lower end of the front end surface of the projecting member 70 is the rear side (the outer side of the outer casing 1). E.g, The angle C ' is a predetermined angle in the range of 0 to 5 degrees. therefore, Has a relationship of angle angle b. When the angle b is set to be large, the angle c may be set smaller, and when the angle b is set to be smaller, The angle c can also be set larger. For example, 'If the angle b is set to 1 degree, The angle c can also be set to 〇. That is, as long as the rear end surface of the spacer 25 is sufficiently inclined, 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 projecting member 70 is opposed to the front side wall surface of the recessed portion 39.

Figure 25, A perspective view of the dust containing portion 5 of the third embodiment of the present invention is seen from the left rear side. Figure 26, The front side of the dust receiving portion 5 of the third embodiment of the present invention is observed from the front side - 66 - 201200092 of the rear side wall surface (front wall surface of the electric blower) of the cleaner body 1 facing the other end in the axial direction. Filter 15, A filter member 79 is formed in the frame 78 having a substantially quadrangular cross-sectional shape. Protrusion 73, It is formed at the left and right sides of the lower portion of the frame 78 of the filter 15. Concave 81, The left and right sides of the lower portion of the rear side wall surface (the front wall surface of the electric blower 28) of the cleaner body 1 and the frame body 78 of the filter 15 are formed. also, The filter 15 is formed with a convex portion 73, Instead of the recess 81 formed in the rear side wall surface of the cleaner body 1, Forming a recess 8 1 in the filter 15 A convex portion 73 may also be formed on the rear side wall surface of the cleaner body 1. In Figure 26, Auxiliary filter 26 (inlet opening of suction duct 27), It is formed in the rear side wall surface of the cleaner body 1 near the left side. On the upper side of the rear side wall surface of the vacuum cleaner body 1, A housing portion 8 2 accommodating the dust removing device 24 is formed. On the outermost peripheral portion of the rear side wall surface of the cleaner body 1, That is, corresponding to the position of the spacer 25, A gasket receiving surface 80 is formed to receive the gasket 25. The gasket bears the face 80, In order to include at least a substantially quadrangular portion wider than the width of the spacer 25, In order to easily accept the spacer 25, Preferably, the substantially quadrangular portion is formed by a flat surface. The gasket bears the face 80, The surface formed by the auxiliary filter 26 or the accommodating portion 82, It is formed to protrude toward the front side of the cleaner body 1. The direction in which the spacer receiving surface 80 is formed when viewed from the side is in order to be able to form along the rear end surface of the spacer 25, The angle b 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. therefore, The gasket bears the face 80, With respect to the face on which the auxiliary filter 26 or the accommodating portion 8 2 is formed, It is also inclined at an angle b. Relative to the position of the upper end of the gasket receiving surface 80, The gasket bears the position of the lower end of the face 80, It is on the front side (the side of the dust accommodation part 5). The sealing mechanism (seal member) is realized by the gasket 25 and the gasket receiving surface 80' and -67-201200092. Figure 2, Figure 7, The front view of the dust separating portion 4 of the third embodiment of the present invention is seen from the front side. Protrusion member 72, It is formed on the upper side of the inlet pipe 3 which is formed on the outer side of the one end surface in the axial direction of the dust separating portion 4. In the left and right direction, Projecting member 72, It is formed in the center part of the dust separation part 4. Projection member 72, It is formed to have a wide width toward the left and right direction. but, Protrusion member 72, It is also possible to constitute a plurality of projecting members 72 arranged in parallel in the left-right direction. also, The dotted line in Figure 27, To show the step difference formed on the inner surface of the outer cylinder 6. Figure 28, A side view of the dust separating unit 4 and a front side view of the cleaner body of the third embodiment of the present invention. a protruding member 72 formed in the dust separating portion 4, To extend in the axial direction of the dust separating portion 4, That is, extending toward the front side wall surface of the cleaner body 1, The front end portion is provided with a convex portion. that is, Protrusion member 72, It has a claw shape or an L shape. Another aspect, At a position corresponding to the protruding member 72 of the front side wall surface of the cleaner body 1, An engaging hole 82 is formed to receive the protruding member 72. The engaging mechanism (the engaging member 71) or the mechanism for restricting separation is realized by the protruding member 72 and the engaging hole 82. user, When the dust separating unit 4 is attached to the cleaner body 1, First, the protruding member 72 is inserted into the engaging hole 82, Thereafter, The inlet opening end of the inlet pipe 3 is abutted against the gasket 22' attached to the cleaner body 1 and thereafter, as long as the other end of the dust separation portion 4 in the axial direction is disposed, It is sufficient to press the engaging member 71. If the electric blower 28 is operated to generate an attraction force, The dust separating portion 4 will float from the cleaner body 1, However, the convex portion of the front end portion of the protruding member 7.2, Will abut against the inner side wall of the engaging hole 8 2 and get stuck -68-201200092, One end in the axial direction of the dust separating portion 4 can be suppressed from being displaced or separated from the front wall surface of the cleaner body 1. therefore, It is also prevented that one end of the inlet pipe 3 in the axial direction is displaced or separated from the gasket 22, It suppresses the decrease in attractiveness or the generation of noise. Instead of the dust separating portion 4, the protruding member 72 is formed, Forming the engaging hole 8 2 on the front side wall surface of the cleaner body 1, A protruding member 72 may also be formed on the front side wall surface of the cleaner body 1, The engagement hole 82 is formed in the dust separating portion 4. The formation position of the protruding member 72, It may be an end surface in the axial direction of the dust separating portion 4 or a side close to the upper end. It can also be on the lower side of the inlet pipe 3. also, 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 of the tip end may be formed on the front side of the cleaner body 1. A pressing member for pressing the upper end surface of the inlet pipe 3 may be formed on the front side of the cleaner body 1. [Embodiment 4] The details of the dust accommodating portion 5 of the first embodiment are This will be described as Example 4. An electric vacuum cleaner of Embodiment 4 of the present invention, Its characteristics are: Ventilation components can be used (for example: Dust box 1 2 ), Rotating from the first state in which the venting member covers the outer casing toward the front direction of the outer casing to the angle at which the opening surface of the venting member forms a horizontal direction (for example: The angle e - the angle f) is the second state of the predetermined angle within 45 degrees. Or, this invention, For ventilation components (for example: Dust box 1 2) from the inside of the ventilation member or the outer casing! The state 'turns toward the front direction of the outer casing to the opening face of the venting member and forms an angle with the direction in which the hand is formed - for example: The angle e_angle f - angle h) is the second state of the predetermined angle within 45 degrees. and, According to the invention, The ventilating member can be rotated toward the front direction of the casing until the angle at which the opening surface of the venting member forms a predetermined angle with the horizontal direction within a predetermined angle of 45 degrees. Alternatively, the ventilation member can be rotated toward 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 becomes a predetermined angle within 45 degrees. The user can easily discharge the dust accumulated in the ventilation member. Or, An electric vacuum cleaner of Embodiment 4 of the present invention, Its characteristics are: a mounting member for mounting a ventilation member (for example, the dust box 12) to the outer casing, Look at the dust collection from the side (for example: When the dust accommodation part 5) The direction in which the rear end surface of the dust collecting portion is formed is fixed obliquely to the outer casing with respect to a perpendicular line perpendicular to the bottom surface of the cleaner body. And 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 in which the rear end surface of the dust collecting portion is formed is inclined with respect to a perpendicular line perpendicular to the bottom surface of the cleaner body, It is not necessary to make the front and rear directions of the dust collecting portion long. It can increase the strength of the mechanism that installs the dust collecting part on the outer casing. It also suppresses the deflection of the outer casing. Figure 29, The front view of the dust containing portion of the fourth embodiment of the present invention is seen from the front end side in the axial direction. In particular, the state other than the front cover 11 is displayed. Same as Figure 6, Compared to Figure 6, Figure 29 is a flow diagram 62 showing the dust box 12, And the state of accumulation of the dust 83 in the dust collecting case 12. As shown in Fig. 26, the inlet opening of the suction duct 27 is in the left-right direction of the cleaner body 1, Formed near the left side. And as shown in Figure 5 (-70-201200092 B), The outlet opening ' of the outer flow path 35 is formed on the upper side than the center line of the front cover 1 1 in the up and down direction, It has a shape that is symmetrical in the left and right direction. also, The airflow 62 that is swirled over the outer peripheral side of the inner cylinder 7 as shown in Fig. 1 In order to flow into the outer flow path 3 5 ' in the circumferential direction (the whirling direction), it is turned toward the axial direction by the downstream side wall surface 65. But even if the downstream side wall surface 6 5 turns toward the axis, The component in the circumferential direction (cycloid direction) remains in the airflow 62. Therefore, the airflow 62, The other end portion in the axial direction of the dust separating portion 4 of the outer flow path 35 (the intermediate portion of the outer flow path 35), The one end portion in the axial direction of the front cover 11 (the intermediate portion of the outer flow path 35) also faces the axial direction and faces the circumferential direction. The other end portion in the axial direction of the front cover 11 (the outlet portion of the outer flow path 35) also faces the axial direction and faces the circumferential direction. that is, As shown in Figure 29, Airflow 62, In the inlet opening portion in the dust box 12, Not only the axial direction but also the circumferential direction of the half turn clockwise. therefore, Airflow 62 in the dust box 1 2, Not only is it directly inhaled towards the filter 15, Also colliding with the left side wall of the dust box 12 facing the left direction in the circumferential direction, It collides with the bottom surface of the dust box 12. An airflow 62 that collides with the bottom surface of the dust box 12, Re-impact on the right side wall of the dust box 12, After swirling toward the other end of the inlet opening of the dust box 12, that is, the axial direction of the front cover 11, It merges with the initial airflow 62 flowing into the dust box 12. therefore, The air that flows into the dust box 12 will be inside the dust box 12, Produced on the side of the body, left, Far side, right, a swirling airflow 62 on the near side (when the dust receiving portion 5 is viewed from above, For a clockwise rotation). In particular, when the dust collecting box 12 is formed with a mesh member, the collision or swirl of the airflow 62 is more remarkable. but, Since the bottom surface of the dust box 12 and the side walls of the upper, lower, left and right sides are ventilated, the openings are opened. Therefore, a flow of air 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 is also generated. 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, Due to the strong swirling force of the airflow 62, Therefore, the dust contained in the air, For the centrifugal separation caused by the swirling flow, It is flying toward the outer peripheral side of the swirling flow, It accumulates in the upper right portion of the dust box 12. that is, dust, It is gradually accumulated from the upper right portion of the dust box 12. therefore, Also regardless of the inlet opening of the suction duct 27 being present on the left side, Dust 8 3 is accumulated from the right side, Therefore, even if dust 83 is accumulated in the dust box 12, It is also not easy to hinder the generation of the swirling flow. Further, the portion corresponding to the inlet opening of the suction duct 2 is not easily blocked by the dust 83. Therefore, the accumulation of dust 83 is inhibited by the energy loss of the air. It is possible to suppress a decrease in the attractive force caused by the accumulation of the dust 83. also, When the dust 83 accumulates from the upper right portion of the dust box 12, Since there is also a flow of air from the bottom surface of the dust box 12 and the side wall surfaces of the upper and lower sides toward the dust box 12, Therefore, the bottom surface of the dust box 12 and the side walls of the upper, lower, left and right sides, The dust will also attach to it. Figure 30, A cross-sectional view of the dust receiving portion of the fourth embodiment of the present invention is seen from the side. In particular, the display is relative to the outer casing 1 The front cover 11 is in a closed state. The outer flow path 3 5 ' is a position in the cover 1 1 before the end face of the front cover 11 is axially extended. Suddenly zoomed in. Furthermore, At a position beyond the other end surface of the front cover 1 1 in the axial direction of the outer flow path 35 (the outlet opening of the outer flow path 35), the position inside the housing 12 is Also suddenly enlarged. therefore, Airflow 62, The position in the cover 11 is suddenly slowed and spread before the end face of the front cover 11 is exceeded. Furthermore, The position inside the dust collecting box 12 exceeding the other end surface (outlet opening) of the front cover 11 in the axial direction also suddenly becomes slow and spreads. -72- 201200092 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 is also the joint portion between the bottom surface of the dust box 13 and the upper side wall surface. Compared with the lower end of the bottom portion 84 of the dust box, that is, the joint portion between the bottom surface of the dust box 13 and the lower side wall surface, To set the radius of curvature larger, And formed gently. The axial direction of the dust box 12, Since it is inclined at an angle a with respect to the axial direction of the filter I5, Therefore, the lower end of the bottom 84 of the dust box, In the dust box 13, the filter 15 is connected to the nearest one. A line connecting the center point of the upper and lower sides of the opening of the outer side flow path 35 in the axial direction of the front cover 11 and the center point of the one end surface (inlet surface) of the axial direction of the filter 15 (the entrance surface) is connected ( Line), The lower end of the bottom portion 84 of the dust box is located substantially. And , The airflow 6 2 flowing into the dust box 12, To face the filter 15, And diffusing from a position exiting the outlet opening of the outer flow path 35, A part is along the upper side wall surface of the dust box 12 toward the bottom 84 of the dust box. The other part is to collide with the bottom 84 of the dust box and to swirl along the lower side wall surface of the dust box 12 toward the inlet opening of the dust box 12. Due to the upper side wall surface of the dust box 12, Formed along the direction of the filter 15 toward the airflow 62, Therefore, it is easy to flow toward the bottom portion 84 of the dust box. on the other hand, Due to the lower side wall surface of the dust box 12, Formed in a direction opposite to the direction of the airflow 62 toward the filter 15, Therefore, the air flow is easy to stay. The upper side wall surface of the dust box 12, It is located on the upstream side of the lower side wall surface of the dust box 12, also, Due to the strong swirling force, So dust 83, It is accumulated from the upper end of the bottom portion 84 of the dust box 12. also, On the outer side of the upper end of the bottom portion 84 of the dust box, It is provided with a projecting member 87 which has a restricted dust box 12 and which is ejected toward the front side of the casing 10. Projection member 87, Preferably, it is formed to extend in the radial direction of the circle which is the center of the axis 14 which is the pivot point of the dust box 12. or, Protrusion -73- 201200092 Component 8 7, It is preferred to have a surface along the radial direction. An enlarged view of Figure 30, To show the support structure for the outer casing 10 of the dust box 12. Figure 31, The rear view of the dust containing portion 5 of the fourth embodiment of the present invention is seen from the rear side. In particular, the display is relative to the housing 10, The state in which the filter 15 is turned on. As shown in the enlarged view of Figure 30, The dust box 12 is attached to the inner side of the casing 10 by a mounting member 85. With this, The appearance damage of the outer casing 10 can be suppressed. As shown in Figure 31, The mounting member 85 is provided with a substantially quadrangular shape. It has a certain width in the front and rear direction and the left and right direction. At both ends of the mounting member 85 in the left-right direction, A protrusion 86 is formed. By embedding the projection 86 into a portion of the outer casing 10 (a portion formed from the lower surface of the outer casing 10 extending in the oblique direction in the outer casing 10), The mounting member 85 is fixed to the outer casing 1 〇. then, The shaft 14 is supported on the front side of the mounting member 85. On the axis 1 4, It is also possible to provide 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. and, When the dust box 1 2 is ejected toward the front side, The mounting member 85 will remain on the side of the outer casing 10, With the shaft 14 as a fulcrum, only the dust box 12 is displaced toward the front side. here, Mounting member 8 5, With respect to the bottom surface of the cleaner body 1 or the surface on which the cleaner body 1 is placed, and the direction perpendicular to 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 receiving portion 5 or the outer casing 10 in the axial direction is formed, It is formed toward the oblique direction. Mounting member 8 5, With respect 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, It may also be formed in a direction that is substantially perpendicular. The dust receiving portion 5 and the outer casing 19, The shape viewed from the side is a substantially inverted triangle or a substantially fan shape. That is, compared to the above, The bottom is shorter. In such a dust accommodating portion 5, When the mounting member is formed in a horizontal direction as in Patent Application No. -74-201200092, The lower side of the dust accommodating portion 5 becomes longer, and the length of the dust collecting device 2 in the axial direction also becomes longer. The length of the suction device body 1 in the front-rear direction also becomes long. If the mounting member 85 itself is shortened, The strength for fixing the mounting member 85 to the outer casing 10 is insufficient. Especially when the coil 14 is formed with a coil spring, Since a reaction force is generated for the elastic force of the coil spring of the mounting member 85, Therefore, the mounting member 8S becomes easy to bend, Damage. And in the state in which the dust box 12 is ejected, The load applied to the dust box 12 is also imparted to the mounting member 85. So it will become easier to bend, damage. here, In order to make the mounting member 85 long (1/2 or more of the axial length of the dust collecting case I2), And, Shorten the lower side of the dust receiving portion 5, And the component 85 will be installed, 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 cleaner body 1 is placed, Or the direction in which the other end surface of the dust receiving portion 5 or the outer casing 10 is axially oriented, Formed in an oblique direction. In Figure 31, user, By pressing the portion of the mounting member 85 that is "pressed", The dust box 12 is unloaded from the outer casing 1 together with the mounting member 85. Figure 3 2, A cross-sectional view of the dust receiving portion of the fourth embodiment of the present invention is seen from the side. In particular, the display is relative to the housing 1〇, The front cover is open, The dust box 12 is in a state of being ejected toward the front direction of the casing 10. As shown in Figure 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 surface in the axial direction are formed and the direction in which the one end surface of the outer casing 10 is formed are perpendicular to the axial 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 are formed, and the direction in which the one end surface of the outer casing 10 - 75 - 201200092 is formed in the axial direction, It is inclined (180-a) degrees with respect to the vertical direction (gravity action direction), It is inclined at a substantially angle a with respect to the horizontal direction (a direction perpendicular to the direction in which the gravity acts). therefore, The direction in which the end face of the outer casing 10 is oriented in the axial direction, Tilting angle e relative to the horizontal direction, This angle e is approximately equal to the angle a. therefore, E.g, Angle e, The same angle as the angle a is a predetermined angle in the range of 40 degrees to 45 degrees. Front cover 11, Rotating from the front direction toward the lower side with respect to the outer casing 10 with the shaft 3 1 as a fulcrum, However, as shown in Fig. 32, the one end surface in the axial direction of the front cover 11 and the direction in which the other end surface is formed in the axial direction are at least substantially perpendicular to each other. Front cover U, a direction in which an end face is formed in the axial direction of the outer casing 10, It can be opened at least at an angle (e + 90) degrees. Front cover 11, With respect to the direction in which the end face of the outer casing 10 is formed, It is preferable that the opening is larger than the angle (e + 90 ). also, The angle of the direction of formation with respect to the plane in the horizontal direction, The angle is the same as the normal direction with respect to the face in the vertical direction. Dust box 12, Accompanying the ejection from the housing 1〇, The outer shaft 1 3 formed in the middle of the bottom portion 8 4 of the dust box is divided into the upper half 8 8 of the dust box and the lower half 89 of the dust box. The upper half 88 of the dust box and the lower half 8 9 of the dust box are relatively open only at an angle g. E.g, Angle g is 1 1. About 5 degrees. The protruding member 87 (a part of the dust collecting case 12) formed on the outer side of the upper half 88 of the dust collecting case is closed to the inner side of the one end surface of the outer casing 1 in the axial direction, and the dust box 12 is ejected and 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 10 in the axial direction. For example, the angle f is about 33 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 of the dust collecting box 8 8 - 76 · 201200092 is the opening end 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 portion 89 of the dust box is close to about 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 (11). . 5 + 7) = 18. About 5 degrees. Therefore, the front end surface of the upper half 88 of the dust box and the front end surface of the lower half 88 of the dust box become closer to the horizontal direction, that is, closer to 45 degrees between the horizontal direction and the vertical direction. In 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, compared with the horizontal direction The 45 degrees in the middle of the vertical direction is closer to the vertical direction, so that the dust 8 3 accumulated in the dust box 12 becomes easy to fall. 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 U 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) ' on 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 holds the front side of the handle 16 to discharge the dust 8 in the dust box 12, the front end surface of the lower half of the dust box 89 is -77-201200092, which is an angle with respect to the horizontal direction. -f+h), for example, close to 19 degrees, the front end face of the upper half 88 of the dust box, with respect to the horizontal direction, is an angle (e-f+g + h ), for example, close to 30·5 degrees about. Therefore, even if the user grips the front side of the handle 16 to discharge the dust 83 in the dust box I2, 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, The dust is close to the horizontal direction, that is, it is closer to the horizontal direction than 45 degrees between the horizontal direction and the vertical direction, so that the dust 83 accumulated in the dust box 2 can be easily dropped. However, it is not necessary that the handle 16 is gently inclined from the rear end of the dust receiving portion 5 to the front side, and the handle 16 may be formed 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, since the user cannot visually recognize the accumulation amount of the dust 8, it is necessary to have the window 74. At window 74, a garbage disposal line 90 is drawn to allow the user to know the period of garbage disposal. The direction in which the garbage disposal line 90 is formed is a direction that is substantially perpendicular to the direction in which the dust 83 in the dust box 12 is stored, that is, a direction that is substantially perpendicular to the suction direction toward the filter 15, that is, relative to the approximate direction. The horizontal direction is a substantially vertical direction. Further, the position at which 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, and is, for example, one end in the axial direction of the front cover Π The corresponding position of the lower end of the opening of the part. 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 of the garbage disposal line 9〇-78-201200092 to a position where the dust 83 is not scattered from the opening of the front cover 11, the dust can be accumulated as much as possible in the dust box 12. By reducing the number of times the user discharges the dust, the burden on the user can be reduced. 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 10 instead of being formed on the front cover 11. Fig. 4 is a cross-sectional view as seen from the right side of the dust containing portion of the fourth embodiment of the present invention. Fig. 34(a) shows the fully open state of the dust box y-2, and Fig. 34(a) shows the half open state of the dust box 12. As described above, the projecting member 87 is in contact with the inner side of the outer surface of the outer casing 10 in the axial direction, and is used to restrict the ejection of the dust box 12, and is fully opened as shown in Fig. 34(a). . 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, a projecting member 91 and a projecting member 92 for maintaining the dust collecting case 12 in a half-open state are provided. 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 projection member 911 and the projection 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 projection member 92. In Fig. 34(a), the inclination angle of the left side (front side) of the projection member 91 is preferably larger than the inclination angle of the right side (rear side surface) of the projection member 92. The inclination angle -79 - 201200092 of the left side (front side) of the projecting member 92 is larger than the inclination angle of the right side of the projecting member 92. The inclination angle of the left side of the projecting member 92 is preferably close to 9 degrees (80 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, in the case where the dust box 12 is ejected toward the front of the casing 10, since it has a velocity momentum by the self-weight of the dust box 12 or the spring force of the spring, it will cause an end face toward the axis of the casing 1 The inner protruding end portion 93 of the opening slides over the left side of the protruding member 91, then flies over the gap between the protruding member 91 and the protruding member 92, and slides to the right of the protruding 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, 'by the user's operation', when the dust box 12 is housed in the outer casing 10, when the user's pressing force 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, the end portion 93, slides over the right side of the protruding member 92, and 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, restricting the dust box 12 from being ejected (rotated) toward the front of the outer casing 10, and Become a half open state. Further, from the half-open state, the user applies a pressing force to one end surface of the front cover 1 in the axial direction, so that the front cover 1 abuts against the front surface of the dust box 12, and the end portion 93 slides over the protruding member 9 1 On the right side, the apex of the protrusion member 9 1 is passed over, and then the left side of the protrusion member 9 1 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 also has a tilt-80-201200092 oblique, 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 opened. When the end portion 93 is abutted against the left side of the protruding member 91, the storage state of the dust box 12 can be maintained. Thereby, the 'user' can easily accommodate the dust box 12 in the outer casing 10, and the front cover 11 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 10, and the dust box 12 can be housed in the casing 10 in a state where the front cover 1 is opened. The user can then close the front cover 11. 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 box. The bottom surface of 12 and the side walls of the upper, lower, left and right sides are securely mounted. 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.

It is characterized by it. With respect to the first to fourth embodiments, the fifth embodiment is characterized in that a through hole 105 that communicates with the outside is added between the shim receiving surface 76 of the front cover 11 and the shim receiving surface 77. 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 portion side extends 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 an inner tube 7 having a plurality of through holes in a circumferential surface, and is wrapped in a substantially cylindrical shape. The inside of the cylinder 6 has a flow path (for example, a recessed portion 8 and a guide tube) formed from an end portion (for example, an axial end end side end portion) of the inner cylinder 7 toward the outer peripheral surface of the inner cylinder 7 3 8 ) 'and a portion facing the side wall of the flow path among the inner faces of the end portions on the suction port side of the outer cylinder 6 has a projecting member (for example, ribs 9 5 ). By this, it is possible to sufficiently ensure the airtightness of the end portion of the inner cylinder of the inner cylinder 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 in a substantially cylindrical shape. A projection member (for example, a rib 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). 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 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 shape. The inside of the cylinder 6 and the end of the inner cylinder 7 on the second dust collecting portion side (for example, the axial direction bottom side end portion. There is a sealing member (for example, the spacer 9) between the outer cylinder 6 and a lower side of the outer peripheral surface of the sealing member, and a protruding member (for example, the convex portion 98) is provided. 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 10 04 ) that extends in the axial direction.

Further, the present invention is characterized in that the first dust collecting portion (for example, -83-201200092 dust separating portion 4) and the second dust collecting portion (for example, the dust containing portion 5) are in communication with each other (for example, the front portion) The cover 11) has a hole that communicates a 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, the atmosphere) (for example, , through hole 1 05 ). 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 of 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 end portion on the bottom side in the axial direction of the lip portion 68 and the spacer 9. 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 from the cross section of _84 - 201200092. 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 smaller or slightly larger than the thickness of the outer wall of the outer tube 6. When the inner tube 7 is inserted into the outer tube 6, the outer peripheral surface of the spacer 9 is brought into contact with the inner peripheral surface of the outer wall of the outer tube 6, and the surface of the front end side of the outer 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 airtightness of the inner cylinder 7 and the outer cylinder 6 can be ensured in the axial direction, that is, 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. 36 (a), ribs (protrusions) 95 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 rib 95 is a plate shape having a substantially uniform plate thickness, and is partially curved along a 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 step difference. A range of step difference is formed with respect to the inner side surface of the outer cylinder 7 in the axial direction, and the range in which the ribs 95 are 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 the portion corresponding to the tip end portion of the inner cylinder 6 in the axial direction, although no step difference is formed. The rib 95, also -85-201200092, is bent along the axial end of the inner cylinder 6. Therefore, the inner side of the end surface of the outer tube 7 in the axial direction of the rib 95' is a part from a portion corresponding to the front end portion of the guide tube 38, to a portion corresponding to the front end portion of the inner tube 6 in the axial direction. Formed continuously. However, the rib 95 may not be formed in a 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, when the inner tube 6 and the stomach 7 are combined so that the distal end portion of the guide tube 38 in the axial direction can abut against the step difference, the inner peripheral surface of the rib 95 is the guide tube 38. The outer circumferential surface of the distal end portion in the axial direction and the outer circumferential surface of the distal end portion of the inner cylinder 6 in the axial direction 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 axial end portion of the guide tube 38 and the axial end portion of the inner cylinder 6, so that only the stage difference is formed. It can reduce the energy loss of the air or reduce the noise. Further, as long as the rib 95 is formed, a step difference may not 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) 96 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 front end portion of the cylindrical portion 57 in the axial direction, but may be equal. As shown in Fig. 35, the thickness of the side of the rib 96 from the side of -86 to 201200092 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. The snap hole 97. The engaging hole 97 is formed at a position corresponding to the rib 96 when the inner cylinder 7 is attached to the outer cylinder 6. However, in this case, the engaging hole 97 is preferably slightly larger than the rib 96 in order to facilitate the insertion of the rib 96. The engaging hole 97 is a closed hole. 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 inside the outer cylinder 6 by holding the inner side or the outer side of the recessed portion 39, the rib 96 located on the lower side is inserted into the engaging hole 97 due to the circumferential direction or Since the relative positions of the inner cylinder 7 and the outer cylinder 6 in the left-right direction have 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 from -87 to 201200092, 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, but may be integrally formed of the same material as the spacer 9. On the other hand, as shown in Fig. 36 (b), a concave portion 99 recessed toward the outer peripheral side is formed on the lower side of the inner peripheral surface of the outer cylinder 6. The recessed portion 99 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 concave portion 99 is provided with a shape corresponding to the convex portion 98. The projection 98 is a closed hole. When the user holds the inner cylinder 7 inside the outer cylinder 6 by holding the inner side or the outer side of the recessed portion 39, the user inserts the convex portion 98 positioned at a lower side than the rib 96 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 positional deviation of the relative elasticity of the inner cylinder 7 and the outer cylinder 6 can be suppressed as compared with the case where only the rib 9 6 and the engaging hole 9 7 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 of -88-201200092 is formed on the inner circumferential surface of the outer peripheral wall of the outer cylinder 6, so that it is also relative to the axial direction. Resistance. 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 9 9 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 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. It is possible to suppress the lip portion 68 and the lip portion 69 from being fixed to the spacer receiving surface 76 and the spacer receiving surface 77, or to prevent the spacer 9 from being fixed to the inner peripheral surface of the outer peripheral wall of the outer cylinder 6, It is not 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. 3 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', the ribs 104 of the plate shape extending in the axial direction are formed in the outer flow path 35 of the front cover 11. The rib 10 04 extends in the axial direction from the end to the rear end in the front cover 1 1 . As a result, the outer flow path 35 is formed on the upper side of the rib 1 〇 4, and the flow path -89 - 201200092 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. The ribs 104 may be formed into a substantially L-shape on the lower side of the ribs 168 as long as the dust is accumulated, so that the lower side of the ribs 1 〇4 is a closed space that does not communicate with the dust box 12. In Fig. 39, since the ribs 1〇4 are concealed inside the check valve 103, they are indicated by dotted lines. As shown in Fig. 39, the width of the ribs 104 in the left-right direction is a width which can reach the left-right direction of the outer flow path 35. By the ribs 1, the dust accumulated in the dust collecting case 12 can be prevented from being scattered from the outer flow path 35. Further, since the air flow 6 2 flowing in from the outer flow path 35 by the ribs 1〇4 is in the upward direction, that is, the upper side wall surface of the dust box 12, the swirling force of the air flow 62 can be increased. 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, and the check valve 103 covers only the outlet opening of the outer flow path 35 formed on the upper side of the rib 104. Further, the check valve 103 is rotated toward the dust box 12 by the upper end as a fulcrum. The check valve 103 is preferably made of an elastic material such as rubber. By the check valve 203, it is possible to prevent the dust accumulated in the dust collecting case 12 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 1〇5' 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 (attraction force) of the dust absorber main body 1 is lowered. If the through hole 105 is too small, an appropriate amount of outside air cannot be sucked from the through hole 1〇5. 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. The through hole 1 〇 5 as shown in Fig. 4 is in communication with the outside (atmosphere) of the front cover 11. That is, the through hole 1 0 5 penetrates the front wall of the front cover 1 1 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 which is not in communication with the outer flow path 35 is communicated with the outside from the gap ' between the side wall and the rear wall of the front cover 11. As shown in Fig. 41, the through hole 105 is formed in a state where the dust separating portion 4 is joined (attached) to the dust containing portion 5, and is a space opened between the lip portion 68 and the lip portion 6.9. 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 of 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 'the air flow of the outside air 1 〇 6 is passed from the outside through the front cover 1 The gap between the side wall and the rear wall of 1 flows into the inner side of the cover 1 1 before being in communication with the outer flow path 35 and then flows into the lip portion 68 and the lip portion 69 through the through hole 1〇5' of the front wall of the front cover U. The space between. Then, the airflow 106 of the outside air flows into the outer channel 35 through the portion 100' of the inner peripheral side of the terminal of the outer channel 35 and the airflow 62. That is, 'the airflow 6 2 ' in the first drawing is not flowing from the outlet end ' of the inner cylinder 7 of the outer flow path 3 5 through the inner peripheral side portion of the terminal end of the outer flow path 35 The space between the lip portion 68 and the lip portion 69 is inwardly flowing 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 side flow path 35. The inner air of the inner tube 7 of the flow path 35 is -91 - 201200092 The external air at the outlet end becomes confluent. Therefore, the through hole 105 prevents the dust contained in the air flow 62 from being caught by the portion 1 〇〇 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. As long as it is at the outlet end of the inner tube 7 of the outer flow path 35, the lip portion 68 and the lip portion 69 on the downstream side of the air current 62 can be used. 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. [Embodiment 6] The other shape of the front cover 11 shown in the fifth embodiment will be described as a sixth embodiment. In the vacuum cleaner of the sixth embodiment of the present invention, one end of the inner cylinder 7 in the axial direction is configured to swirl the air containing the dust sucked from the inlet pipe of the dust collecting device in a circumferential direction, and to swirl. The air passes through the outer flow path 35 of the front cover 11 and is swirled into the dust box 1 2 . Then, the dust accumulates in the dust box 12, and the air is attracted toward the side of the electric blower. The sixth embodiment is characterized in that the two ends of the outer side flow path 35 of the front cover 1 are formed to be continuous with the shape of the inner wall of the dust collecting case 12, thereby reducing the disorder of the swirl in the dust collecting case 12. . Further, the electric vacuum cleaner according to the sixth embodiment of the present invention is characterized in that a check valve is provided on both the outer flow path 35 and the inner flow path 36 to suppress the scattering of dust when the garbage is discarded, and the outer side The check valve on the side of the flow path 35 is provided with a support portion on the outer peripheral side of the front cover 11 to support the support position as the center of the check valve, and the support width is set to be 2/3 of the width of the check valve. Shape to flow the air entering the dust box 12 to -92-201200092 for rectification. Further, the electric vacuum cleaner according to the sixth embodiment of the present invention is characterized in that the dust collecting device is provided with a stacking box 1 covered by a part of the opening and having a ventilating member (for example, a mesh member 109) 2. A filter 15 disposed on the downstream side of the dust collecting case I2, and a flow path (for example, the outer flow path 35) that connects the main body suction port and the opening of the dust collecting case 12; the air flowing into the flow path It is swirled by the flow path and reaches the opening of the dust box 12, and a part of the outlet end of the flow path is a part close to the opening of the dust box within the manufacturing error range. According to the present invention, the compressibility of the dust contained in the dust collecting case 12 can be improved, and the amount of dust passing through the dust collecting case 12 can be reduced, and the volume of the dust collecting case can be suppressed. Fig. 42 is a front view showing the inside of the dust containing portion in a state in which the front cover 11 of the sixth embodiment of the present invention is not provided with a check valve, and Fig. 4 is a front view of the front cover 11 as seen from the inside of the dust containing portion. The front view, and Fig. 44, is a front view of the front cover 11 as seen from the outside of the dust receiving portion. The front cover 11 is provided with a window 74 formed of a material such as transparent ABS resin to confirm the dust collecting condition. The space 1 〇 4a formed on the lower side by the ribs 104 is such that dust is gradually accumulated when the dust in the dust collecting case 1 2 becomes full, and therefore is provided to notify the time of garbage disposal. The space 1 〇 4a has an opening on the side of the dust collecting box 12 and an occlusion on the other side. Further, since the space 1 〇 4a is sandwiched by the ribs 104, and the outer flow path 35 is disposed closer to the center side of the front cover 11 which is substantially circular in cross section, the dust box 12 of the space l〇4a is disposed. The opening of the side surface has an area larger than the area of the outlet end of the outer flow path 35 (the dust collecting box 12 side) 93 - 201200092. Further, since the shapes of the outer side flow path 35 are enlarged in the left-right direction as compared with the shapes of the outer side flow path 35 shown in Figs. 3 and 3, the space between the window 74 and the window 74 is reduced, and the dust collecting condition can be easily grasped. As shown in Fig. 42, the opening shape of the outlet end of the outer flow path 35 is substantially trapezoidal or substantially half-moon shaped. However, the shape of the opening at the outlet end of the outer flow path 35 may be substantially oblong, substantially elliptical, and substantially rectangular or polygonal. As shown in Fig. 29, the opening shape of the inlet end of the dust collecting case 12 is substantially octagonal or substantially oblong. However, the shape of the opening of the inlet end of the dust box 12 may be substantially circular, substantially elliptical, substantially rectangular, or polygonal. As shown in the fifth embodiment, a rubber check valve is provided in the outer flow path 35. Further, in the sixth embodiment, a rubber check valve is also provided for the inner flow path 36, and the scattering of dust from the inner flow path 36 side can be suppressed. The check valve 107 of the outer flow path 35 is formed into a plate thickness. 1. 0 mm, the check valve 108 of the inner flow path 36 is made to have a plate thickness of 0_5 mm. That is, the thickness of the check valve 108 of the inner flow path 36 is preferably thinner than the thickness of the check valve 107 of the outer flow path 35. Therefore, the flow rate of the inner flow path 36 is smaller than that of the outer flow path 35, and the thickness of the check valve 108 is too large, so that the resistance becomes large and the airflow is seriously impeded. The thickness of the check valve 108 is not limited to this as long as it does not resist excessively and is rotatable during suction. Further, the check valve 108 is fixed by the fixing member 8a and the screw 108b, and is formed to have a larger opening area than that viewed from the outside of the inner flow path 36. Therefore, the fixing member 108a is used as a fulcrum to rotate only in the direction in which the dust collecting box 12 exists. Further, the check valve 107 provided in the outer flow path 35 is provided with a support portion -94 - 201200092 l〇7a on the outer peripheral side of the front cover 1 1 and a wide width of the check valve 107 as a support width. 2/3, supported at the center of the check valve 107. With the support portion 107a as a fulcrum, the surface in the swirling direction is lifted during suction, and the inflow direction can be suppressed, and the inflowing air can be rectified. The support portion 1 〇 7 a is formed in the shape of the outer flow path 35. On the outer peripheral side, the same effect can be obtained even if it is provided on the opposite side. Also, the check valve 1 〇 7 branch. The width of the support is not limited to this, and may be 2/3 or less or more as long as it can be rotated in the whirling direction with the support portion 107a as a fulcrum. At the time of attraction, it is necessary to be able to withstand the shearing force applied to the check valve 107, and in the present embodiment 6', the support width is made 2/3. Also, although the support width is about 2/3, it is supported by 3 points as shown. This is to reduce the rotation of the check valve 107. As described above, as long as it is able to withstand the shear force applied to the check valve 107 when sucking, the desired range of rotation can be obtained. Limited to this. Further, the support position may not be at the center of the check valve 107, but may be close to either one of the left and right sides, but the support portion is not provided on the side of the swirling direction, Fig. 46, which is the 45th state in which the front cover 11 is closed. Figure AA section. Both ends in the left-right direction of the outlet end of the outer flow path 35 are formed to be continuous with the left and right inner walls of the inlet end of the dust box 12 in a state where the step is small. The state in which the step difference is small means a state in which the proximity is within the manufacturing error range. That is, the manufacturing error (before and after 1 mm) is such that the outer flow path 35 can be larger (wide) or smaller (narrower) than the inner wall of the dust box 12. In order to reduce the disturbance of the air flow, it is preferable that the flow path 35 on the upstream side is smaller than the inner wall of the dust box 12 on the downstream side, but it is also large in the manufacturing error level -95-201200092. No problem. The portion following the inner wall of the dust collecting case 12 may be the only direction of the swirling direction (the right side of the outer side flow path 35 of Fig. 42), but it is preferable that the outer side flow path 35 has a continuous shape at both ends. As shown in Fig. 45, the upper end in the up-and-down direction of the outlet end of the outer flow path 35 is also formed to be continuous with the upper inner wall of the inlet end of the dust box 12 in a state where the step is small. Further, as shown in Fig. 46, when the cross section in the vertical direction is observed, it is understood that the direction in which the outlet end of the side wall surface of the outer flow path 35 is formed is in the direction along the axial direction (substantially parallel) of the dust accommodation portion 5. On the other hand, the direction in which the inlet end of the side wall surface of the dust collecting case 12 is formed is not in the direction of the axial direction of the dust containing portion 5, but is directed toward the center from the inlet end of the dust collecting case 12 toward the center. The direction of the side tilt. Therefore, the direction in which the outlet end of the side wall surface of the outer side flow path 35 is formed does not coincide with the direction in which the inlet end of the side wall surface of the dust collecting case 12 is formed. However, it is preferable that the direction in which the outlet end of the side wall surface of the outer side flow path 35 is formed coincides with the direction in which the inlet end of the side wall surface of the dust collecting case 12 is formed. At the same time, the air from the outer flow path 35 flows into the substantially tangential direction of the dust box I2. The arrow shown in Fig. 46 is the air flow swirling in the dust box 12. The air flow 1 1 0a ', which is swirled around the outer circumference of the inner cylinder 7 and passes through the outer flow path 35, flows into the dust collecting box 12 while being swirled. Therefore, as shown in Fig. 46, it is observed that a certain section in the up and down direction can see that the air flow 1 1 0 a flows from right to left in the outer flow path 35. In the vicinity of the outlet end of the outer flow path 35, the air flow 1 1 0a collides with the left side surface ' inside the outer flow path 35 and flows into the dust box 1 2 . The air flow 1 1 〇a entering the dust box 12 is swirled along the inner shape (inner wall) of the dust box 12 as in the air flow 1 1 〇b to the air flow 1 1 〇c. - 201200092 Swirling in such a manner that the collision of the air flow ll 〇 c with the air flow 110 a of the inlet is reduced. By forming the shape of the outer side flow path 35, the disturbance of the air in the dust collecting case 1 2 can be reduced. On the other hand, the shape of the lid 11 before the Fig. 38 (Example 5) is the air flow shown in Fig. 47. Figure 47 is a cross-sectional view taken along line 38 of the A-A section cut in the same manner as Fig. 45. The outer flow path 35' has a large step difference from the inner wall of the dust box 12, and the air flow 111a entering the dust box 12 does not follow the inner wall surface of the dust box 12, and is substantially vertically conflicting with The dust collecting inner side 12a is divided into two directions in which the air flow 111b and the flow 111c are mainly different in the left-right direction. The air flow lUc is turned into the air flow llld and swirled in the dust collecting case 12, and since the air flow 1 1 1 a at the inlet merges from the substantially vertical direction, there is a tendency for the swirling disorder. Fig. 48 is a view showing the shape of the inner wall of the dust collecting box 1 2 at both ends of the outer flow path 35 (Fig. 46), and the outer side of the inner wall of the dust collecting case 12 is formed. Comparison of the dust collecting capacity at the shape of the flow path 35 (Fig. 47). This is a relationship between the dust collection capacity and the amount of open air when the dust collection condition is confirmed from the window 74 provided on the front cover 11 and is judged to be full, that is, when the dust has reached the garbage disposal line 90. The dust that has been attracted to the dust of the general family is mixed with the dust of the fiber dust by 2 times. It can be seen from Fig. 48 that the shape of the cost example 6 (Fig. 4) is a sustainable air volume, and the dust collection amount is increased by about 1.5 times, and the actual dust collection condition is observed. The dust in the dust box 12 is also uniformly deposited. Therefore, according to the shape of the outer side flow path 35 of the sixth embodiment, the compressibility of the dust can be improved. Further, when the air flow (force) of the mesh member 1〇9 with respect to the dust collecting case 12 is vertical-97-201200092, the opening area of the mesh member 109 viewed from the air flow direction is the largest, so it is shown in the first The air flow in the dust collecting case 12 of Fig. 47 has a tendency that fine dust easily passes through the mesh member 109 of the dust collecting case 12. When the fine dust passes through the mesh member 1 〇 9 of the dust collecting case 12, the structure of the filter 15 is accumulated, and it is preferable that the dust passing through the filter 15 is less during maintenance (when the garbage is discarded). The air flow in the dust box 12 shown in Fig. 46 is along the dust box 12 as described above, so that the air flow in which the dust collides with respect to the mesh member 109 in the vertical direction can be reduced, and the mesh can be reduced. The amount of dust of the member 109. Fig. 49 is a view showing the case where the both ends of the outer flow path 35 are connected to the inner wall of the dust collecting case 12 (Fig. 46) and the shape shown in Fig. 47 from the dust collecting case 12. The amount of dust passing through is compared. As can be seen from the figure, when the shape of the outer flow path 35 of the sixth embodiment (fourth and sixth figures) is obtained, the amount of dust passing through the mesh member 109 is reduced. Therefore, according to Embodiment 6 of the present invention, the compressibility of the garbage accommodated in the dust collecting case 12 is improved, and the amount of dust passing through the dust collecting case 12 can be reduced, by minimizing the volume of the dust collecting case 12, The cleaner body 1 is made compact. The number of times the dust is discharged from the dust box 12 is reduced, and the trouble of the user can be saved. Further, the number of times of dust (fine dust) plugged in the filter 15 (the number of times the filter 15 is cleaned) is also reduced, and the trouble of the user can be saved. [Industrial Applicability] The present invention is applicable to an electric vacuum cleaner. -98-201200092 [Brief Description of the Drawings] Fig. 1 is a cross-sectional view of the cleaner body according to the embodiment of the present invention.
