1351495 九、發明說明： C發明所屬之技術領域3 發明領域 本發明係有關於一種具自動清掃設於室内單元之空氣 5 吸入口之空氣過濾器之功能的空氣調節機。 【先前技術3 發明背景 習知空氣調節機之過濾裝置於熱交換器前面設置用以 防止塵埃侵入空氣調節機本體内部之空氣過濾器，空氣過 10 濾器拆卸自如地構成可以手清掃附著之塵埃。如此構成之 過濾裝置不僅需頻繁之保養，且一直至進行保養前之期間 空氣過濾器逐漸為塵埃所堵塞，結果，使通過熱交換器之 風量降低，空調能力降低，而導致消耗電力增大。 因此，以減低空氣過濾器之保養之時間為目的，而提 15 出以刷子掃落清掃附著於空氣過濾器之過濾裝置或以噴嘴 吸引清掃附著於空氣過濾器之過濾裝置（例如參照專利文 獻1或專利文獻2)。 專利文獻1:日本專利公開公報平6-74521號 專利文獻2:曰本專利公開公報2002-340395號 20 【發明内容】 發明之揭示 發明欲解決之問題 然而，在專利文獻1記載之過濾裝置方面，由於以刷子 掃落清掃，故有塵埃沾附於刷子，而必須處理因掃落而堆 ⑧ 5 損，亦可減低清掃時之聲音。 又’若於片材設置多數空隙時，由於吸引清掃之風可 從空隙漏出而引吸塵埃，防止塵埃之落下，故可發揮片材 併用塵埃之分離與吸引造成之高清掃性能。又，由於可平 順進行彎曲部份之片材驅動，故可防止破損，而提高信賴 性。 特別是將複數片材設置成間隙不重疊時，可防止位於 片特空隙之部份之清掃性能的降低。 當使用發泡材作為塵埃分離構件時，除了防止塵埃沾 附外’由於沾附於過濾網之塵埃亦因發泡材之變形而被撥 出以進行清掃，故可獲得更高之清掃性能，亦可減低清掃 時與過濾網之摩擦音。又，當於發泡材使用矽時，可防止 因’耷掃時與過濾濾網之摩擦造成之發泡材的破損，而可獲 得高信賴性。 15 再者，當使發泡材左右方面截面形狀之傳動帶側之長 度較過濾網側之長度長時，可將高清掃性能維持持久，同 夺可有效地從過濾網將塵埃撥出。且由於提高對發泡材彎 曲性之耐久性，故不需保養。 又，當以設置於發泡材之左右驅動側面之片材構成塵 埃刀離構件時，可提高對左右驅動方向之反複彎曲之耐久 拴再者，當於片材使用不織布或樹脂膜而與發泡材接合 了 &咼對發泡材彎曲性之耐久性與變形時之變形之容 易度。 冨將片材在左右藤動側面設置較發泡材短時，可提高過滤 ⑧ 8 網之塵埃之撥出性、對左右驅動方向之反複彎曲之耐久性及變 形時性變形容易度。 圖式簡單說明 第1圖係本發明空氣調節機之室内單元之截面圖。 第2圖係顯示本發明空氣調節機之過濾裝置全體結構 之立體圖。 第3A圖係本發明第1實施形態之吸引喷嘴之立體圖。 第3B圖係沿第3A圖之線A-A之截面圖。 第4圖係顯示第3A圖之吸引喷嘴之清掃動作之正面圖。

吸入室内空氣後，將經熱交換器52熱交換之空氣吹出至室 内之風扇54及配置於熱交換器52之上游之過濾裝置56，藉 風扇54之動作，從由本體50前面至上面而形成之複數吸入 15 口吸入空氣，漂浮於空氣中之塵埃藉設置於吸入口與熱交 換器52間之過濾裝置56去除。 第2圖係顯示本發明空氣調節機之過濾裝置5 6之全體 結構圖。 如第2圖所示，用以去除通過熱交換器52之空氣之塵埃 20 之過濾裝有過濾框架2、用以保持過濾框架之過濾網 & 4及沿過濾網4表面滑動自如之吸引喷嘴6。 、 吸引噴嘴6藉設置於過濾框架2上下端之一對導執8,與 過濾網4保持一定距離而左右平順移動。進一步，於吸引喷 嘴6連結吸引導管10之一端，吸引導管10之另一端連結於吸 11 1351495 引裝置12。吸引導管10形成可彎折之導管，俾不妨礙吸引 喷嘴6之移動。再者，於吸引裝置12連結排氣導管14，而引 導至室外。附著於過濾網4之塵埃從吸引喷嘴6吸引，再經 由吸引導管10、吸引裝置12、排氣導管14而排出至室外。 5 當將過濾裝置56内藏於一般家庭用小型空氣調節機 時，由於須謀求吸引裝置之小型化、小輸出化，故必須可 以小風量發揮強大吸引力，吸引喷嘴6使用將吸引集中於一 部份，以加強吸引力，藉切換其位置，以清掃過濾網4全部 之吸引位置切換裝置。 10 第1實施形態 第3A圖及第3B圖顯示本第1實施形態之吸引喷嘴6之 構造，於吸引喷嘴本體16設置相對於過濾網4全長之長細縫 狀開口部18，進而，於可沿該開口部18驅動之傳動帶20設 置吸引孔22，以僅從開口部18之一部份吸引，且，可驅動 15 傳動帶20，變更要吸引之場所。由於傳動帶20沿吸引喷嘴 本體16,故可為以熔著或接著等而與吸引喷嘴本體16—體 形成之傳動帶引導體件24所引導，進行傳動帶20之引導， 同時，抑制在吸引孔22以外之部份產生吸引外漏之情形。 藉此構造，由於亦可以小風量，以小吸引孔22集中，故通 20 過吸引孔22之空氣風速增大，即使小型之吸引裝置，亦可 發揮強大之吸引力。 又，在傳動帶20之表面，使用片材發揮將附著於過濾 網4之塵埃與過濾網4分離之塵埃分離構件功能之片刷26固 定於吸引孔22旁邊，藉傳動帶20之驅動，片刷26之位置亦 12 ⑧ 可隨吸引孔22—同變更。若為此結構，由於需變更吸引位 置與片刷位置之驅動裝置僅需傳動帶20之驅動裝置即可， 故結構簡單，且可以低成本實現，故可經常維持吸引孔22 與片刷26之位置關係。 5 如第4圖所示，過濾網4之全面清掃藉驅動吸引喷嘴6 之傳動帶20，改變吸引孔20與片刷26之位置，沿過濾網4左 右驅動吸引噴嘴6,以使吸引孔22與片刷26反複進行圖中箭 頭所示之來回動作而進行。吸引孔22與片刷26設定成過濾 網全長之約1/4長度，藉圖中箭頭所示之來回清掃動作，清 10 掃過濾網4全面。 此外，第3B圖所示之片刷26之高度hi根據與過濾網4 之距離而設計。過濾網4與吸引喷嘴6之距離設計成在吸引 喷嘴6之軸方向中心1.5mm，即使過濾網4有彎曲（最大為 1mm)，亦不致接觸。因而，當過濾網4之彎曲於與吸引喷 15 嘴6之相反方向產生時，吸引喷嘴6與過濾網4最大相距 2.5mm。hi設定為5.0mm，俾在此狀態，片刷26亦可完全接 觸過濾網4。片刷26係使用接著劑等而固定於傳動帶20，當 清掃時’由於持續摩擦過濾網4，故需強力接著。因此，在 本實施形態中，片刷26藉使片材呈L形，而與傳動帶20接著 20 之部份面積大，以加強固定力。當使用此形狀時，由於資 曲成L形之部份易倒向傳動帶20之方向，故以傳動帶引導件 24予以支撐’以保持[形狀態。由於呈L形係因對接著面積 有用之故，故為倒T字形或與此相似之其他形狀亦可。 在家庭用小型空氣調節機中，由於過濾網4位於頂面及 (?) 13 1351495 前面，故如第2圖所示，吸引喷嘴6沿此呈彎折形狀。因而， 雖片刷26亦因傳動帶20之驅動位置而呈彎折狀態，但由於 片材相當薄，故彎曲部可變形成波形，而可無問題地驅動。 此外，在第3A圖中，未圖示片刷之彎曲部呈波形。由於傳 5 動帶20及片刷26要求拉伸強度及對磨損之耐久性，同時， 亦要求對彎曲之柔軟性，故材質宜使用橡膠或樹脂膜。特 別是樹脂膜為PET(聚對苯二甲酸乙二醇酯）或PEN(聚萘二 甲酸乙二酯）之樹脂膜在強度、柔軟性及耐久性上相當優 異，從其機械強度，可使傳動帶20薄至75〜100微米左右， 10 故吸引喷嘴6亦可構成薄型，而提高收納性。結果，亦可使 室内單元本體薄型化，從設計性之面而言亦佳。且成本面 而言，材料費、加工費亦極低價。 當片刷26根據材質之特性使用橡膠時，使用厚度0.5〜1. 0mm左右者，若使用樹脂膜時，則使用50〜75微米左右者。 15 第5圖為片刷26之一部份（第3A圖之B部份)之放大圖， 顯示接著加工前後之狀態，由第5圖可清楚明白，可非常簡 單地將片刷26固定於傳動帶20。特別是傳動帶20與片刷26 兩者皆使用樹脂膜時，由於可熔著（熱熔著或超音波熔著）， 故較以接著劑所作之固定，可進行極強之固定。 20 以下說明如以上構成之過濾裝置56之動作、作用，首 先說明刷子使用毛刷時之刷子及塵埃之狀態。 第6A圖及第6B圖顯示使用毛刷之吸引喷嘴之構造 圖，在傳動帶20之表面上，於吸引孔22旁邊固定毛刷28。 由於此毛刷28具有將附著於過濾網4之塵埃撥落之作用，故 ⑧ 14 連以吸引力亦無法從過濾網4撥落而無法清掃之塵埃亦可 吸引清掃。毛刷28多使用起毛布。毛刷28藉傳動帶2〇之驅 動而與吸引孔22—同改變位置，而經常存在於吸引孔22旁 邊’而以毛刷28撥落之塵埃從吸引孔22吸引。 然而，在使用毛刷28之吸引喷嘴6中，隨著過濾網4之 清掃次數增加，塵埃沾附於毛刷28，而使過濾裝置之清掃 性能降低’而需定期進行毛刷28之保養。 第7圖係使用毛刷28時之吸引喷嘴之清掃時之吸引喷 嘴截面例示圖。實線箭頭表示吸引之風，反白箭頭表示吸 引噴嘴6之去程動作時之行進方向。毛刷28相對於吸引喷嘴 6之去程動作之清掃進行方向而安裝於吸引孔之後方。白色 圓圈表示乾燥塵埃等易吸引之塵埃，黑色圓圈表示因油脂 或香煙之油圬等強力附著於過濾網4之不易吸引之塵埃。清 掃時，易吸引之塵埃於接觸毛刷28前即被吸引，而不易吸 引之塵埃則於以毛刷28撥落後被吸引。此時，如圖中所示， 含油脂等不易吸引之塵埃大量沾附於毛刷28表面，即，隨 清掃增加，許多塵埃進入毛刷28内部，而使毛刷28呈相當 骯髒之狀態。結果，不僅過濾裝置之清掃性能降低，且當 沾附毛刷28之塵埃大幅成長而掉落時，因吸引該塵埃而堵 塞吸引孔之可能性亦大增。且由於塵埃有雜菌繁殖，故對 衛生不佳β 用於本實施形態吸引喷嘴6之片刷26係解決上述毛刷 28固有之問題者’且實現不產生塵埃沾附之吸引喷嘴6。 第8圖係本實施形態清掃時之吸引喷嘴之截面模式 圖’以截面觀看吸引清掃時之吸引噴嘴6及過遽網4之狀態 者。第8圖之箭頭及圓圈等係表示與第7圖相同者。 第8圖係顯示第3A圖中有吸引扎22之部份，即α·Α截面 狀態。由於吸引孔22位於片刷26前面，故乾燥之塵埃等因 吸引力而從過濾網上撥落，而被吸引去除。因油脂等單憑 吸引力無法去除之塵埃則是於吸引孔22通過後而來之片刷 26—面柔軟變形，面緊貼於過濾網4之表面後，拂拭過滤網 4表面，而將之從過濾網4上撥落。所撥落之塵埃為位於附 近之吸引孔22所吸引，而進行清掃。藉拂拭過濾網4表面來 進行清掃，較一面使毛咬合過濾網4，一面清掃之毛刷之且 力小，左右驅動吸引喷嘴6之馬達亦為小輸出、小型，而在 馬達之溫度上升等信賴性方面亦有利。可使用小型馬達在 至内單7C本體之設計面具有自由度大之優點。由於毛刷％ 柔軟，故即使過濾網4變形或彎曲，片刷26亦對應此而變 形，使片刷26前端無間隙地緊貼於過濾網4,故將塵埃撥落 之能力高，清掃性能相當優異。另―方面，正因為其柔軟 性’故不致將塵埃擠出至過瀘網4之對側（熱交換器侧卜亦 有為片刷26強制撥落之塵埃堆積於片襲前端部之情形， 該等塵埃在堆積至H度時便触“姆。片刷練 毛刷不同，無塵埃沾附之處’且由於表面平滑，塵埃不易 沾附。即使附著於表面，與過濾網4摩擦時便可脫落。因而， 藉使用片刷26’可將清掃性能維持持久，且亦不需清洗刷 子之保養。 第2實施形態 1351495 第9A圖及第9B圖顯示本發明第2實施形態過濾裝置56 之吸引喷嘴之構造，本實施形態在於片刷26A設置複數縫隙 之點與上述第1實施形態不同。 如第9A圖及第9B圖所示’縫隙從片刷26A之前端進入 5 至根部（傳動帶20側之面）’形狀切割成v字形般進入’而於 缝隙之部份產生間隙。 第10圖顯示片刷26A之一部份（第9A圖之E部份）之放大 圖，顯示接著加工前後之狀態。如第丨〇圖所示，進入片刷 2 6 A之縫隙之間隔為2 mm間隔，各縫隙前端部份之尺寸切割 10 成V字形而為1mm。由於過濾網4使用40網格（1英时有40條 過濾網纖維），故過濾網4之纖維間之距離為0.64mm，當使 片刷26A之前端為〇.64mm以上時，可防止片刷26A進入過據 網4之網眼而勾住而導致破損》在本實施形態中，由於過滤 網4之網眼間隔亦有不等，故從邊緣而言亦設定為lmm。如 15 此’片刷26A之尺寸（特別是前端部份之尺寸）宜設計大於過 濾網4之間隔。若網眼之網格細，片刷26A之縫細間隔亦可 較小’而若於片刷26A使用諸如75〜100微米厚度之樹脂膜 時，從拉伸強度等觀點而言過細並不佳。 以下說明如以上構成之過濾裝置56之動作、作用。 20 片刷26A擔任將塵埃從過濾網4撥落之角色在第1實施 形態亦已說明。將此塵埃撥落之動作在片刷2 6 A拂拭過渡網 4上亦有效果，再者，當片刷26A以彈性力而回復至原本之 形狀時，若利用將塵埃彈落之效果，可獲得強力之撥落能 力。 ⑧ 17 第11A圖及第11B圖係以模式圖表示其效果者，第 圖係於清掃途中，片刷26A為過滤網4所拖_，而㈣2 引噴嘴6之行進方向於後方大幅變形之狀態。該變形量於大 量塵埃或強力沾黏於過濾網4之塵埃接觸片刷26八時增大。 又，該變形量於塵埃開始堆積於片刷26A前端時亦增大。當 此變形量超過一定之值時，原本相對於傳動帶2〇表面呈垂 直之片刷26A因彈性力而返回原狀（垂直）。 第11B圖為此狀態，在此時之形態，塵埃彈落至吸引孔 側而被吸引去除。由於此時之力強大，故較大之塵埃或沾 點之塵埃亦可被彈落。當於片刷26A設置複數縫隙時，因此 而產生之薄片各自頻繁地進行此動作，故相較於未進入縫 隙時’可大幅提高將塵埃撥落之能力。且，此效果於物性 上特別是使用PET或PEN之樹脂膜時顯著。 又，藉於片刷26A設置複數縫隙，可增加片刷全體之柔 軟性。結果’即使過濾網4有彎曲或凹凸，亦可依其形狀接 觸片刷26A，而連角落亦可清掃。 再者’當於片刷26A設置複數縫隙時，除了提高清掃性 能外’亦具有驅動上之優點。 第12圖係本實施形態之吸引喷嘴之橫截面簡略圖，其 係僅描繪第9A圖之吸引喷嘴本體16、傳動帶20、吸引孔22 及片刷26A者。為清掃過爐、網4全面，而驅動傳動帶2〇，以 改變吸引孔22之位置者已如先前所說明。在本實施形態 中’藉於片刷26A設置複數細小之縫隙，於通過吸引喷嘴6 之彎曲部時，以縫隙加以細分之片材重疊而形成彎曲部， 而不如如第i實施形態般變形成波形亦可。因而由於不施 加過度之力於片刷26A，故不致發生惡化而可提高对久 性、永久性。特別是’藉將缝隙放入乂字形如第⑽所示， 片刷26A之重疊部份亦可減少，故片刷26a之惡化亦減少。 又，在本實施形態中’如先前所說明，將縫隙從片刷 26A之前端至根部（傳動帶側2〇之面）切割成v字形而置入， 可產生間隙，此有助於將相對於吸引孔位於片刷26A對側之 塵埃帶至片刷26A附近。在第1實施形態中，片刷26妨礙從 吸引孔22吸引之風，相對於吸引孔22位於片刷26A之對側之 塵埃吸引力便完全無作用。特別是過濾網4垂直時，若有穿 過片刷26之塵埃時，由於吸引力不作用而掉落，以致於弄 辨室内單元本體。然而，當於片刷26A置入複數縫隙，並於 該等縫隙分別設置間隙時，吸引之風可從該間隙通過，故 穿過片刷26A之塵埃亦可吸引清掃。 第13圖係本實施形態之吸引喷嘴6清掃時之模式圖，圖 中之白色箭頭為吸引之風，其大小表示風之強度。從第13 圖可知，在片刷26A之對側，風通過間隙。又從第13圖可看 出藉使片刷26A之縫隙寬度大於過濾網4之網眼寬度，而不 致勾住過濾網4之網眼之狀態。 又，於片刷26A置入複數縫隙，設置間隙，進行反複進 行第4圖所示之吸引喷嘴6之來回動作之清掃動作時’由於 片刷26A不接觸過濾網4，故僅間隙部份清掃性能降低。 因此，如第UA圖及第14B圖所示，當於吸引孔22旁邊 將有間隙之複數片刷2 6 A設置成間隙不重疊時，藉吸引喷嘴 26之來回動作，片刷26A接觸過濾網4全面。此時，由於吸 引之風亦通過間隙，故片刷26A對側之塵埃亦可吸引清掃。 又，在第14A圖及第14B圖中，將2個片刷26A配置於吸 引孔22之一侧，而如第15A圖及第15B圖所示，將2個片刷 26A分別配置於吸引孔22兩側。特別是若為後者時，具有為 吸引孔22吸引之風為2個片刷26A所引導，2個片刷26A可防 止所吸引之風之擴散之效果，故可高過濾網4表面之吸引風 速，而提高清掃性能。 第3實施形態 第16A圖及第16B圖顯示本發明第3實施形態過濾裝置 56之吸引喷嘴構造，本實施形態在將使石夕如海綿般發泡之 發泡矽刷30固定於傳動帶20之點上與上述第丨實施形態不 同。 在第16B圖中，發泡矽刷30設計成寬度汜為5111111，高度 h2為5mm。寬度係考量清掃性能與驅動時之阻力而決定， 亦因矽之材質而不同。高度如第1實施形態所說明設計成 5.0mm，俾使過濾網4及吸引喷嘴之最大距離為2 5mm亦町 完全接觸，若為發泡材時，為過濾網4所按壓而稍微塵縮之 狀態為正常狀態。 以下說明如以上構成之過濾裝置56之動作作用。 第17圖為本實施形態之清掃時之吸引喷嘴截面模式 圖，以截面觀看吸引清掃過濾網4之途中之吸引噴嘴6與過 濾網4之狀態。圖中之實線箭頭表示吸引之風，反白箭頦表 示吸引喷嘴6之來回動作之行進方向。又，過滤網4上之圓 1351495 圈記號表示附著之塵埃(藉過濾網4去除之塵埃）。白色圓圈 表示乾燥塵埃等易吸引之塵埃，黑色圓圈表示含些微油脂 等而不易吸引之塵埃，黑色三角形表示含許多油脂而非常 難吸引之塵埃。發泡矽刷30相對於吸引喷嘴6之去程動作之 5清掃進行方向而安裝於吸引孔22之後方。 第17圖顯示第16Α圖之有吸引孔之部份，即F_F截面之 狀態。 10 15 20 在清掃之去程動作上’由於吸引孔22位於發泡矽刷3〇 則面，故乾燥之塵埃（白色圓圈）等以吸引力從過濾網4上撥 落而被吸引去除。因油脂等單憑吸引力無法去除之塵埃（黑 色圓圈）則是於吸引孔22通過後而來之發泡石夕刷3〇一面柔 軟變形’―面緊貼於過據網4之表面後，拂拭過據網4表面， 而將之從過_4上撥落。騎落之塵埃為位贿近之吸引 孔22所吸引而進行清掃。然而，含許多油脂而非常難吸 引之塵埃（黑色三角形）無法以此去除，而沾黏於過滤網4 上。此種雜藉使用如海綿般柔軟之發泡材作為刷子如 第17圖之放大圖所示，發泡材—面柔軟變形，—面進入過 慮網4之網眼間，如包住沾黏之塵埃般將該等捕集而於過遽 ，·周4表面撥dj此效果因發泡材表面之細孔而大為發揮。如 此塵埃藉擦拭過攄網4表面而收集成毛球狀，此毛球從刷 子^ ,出此撥出之毛球以發泡材摩擦而易從過濾網4 撥洛’且成毛球而使表面積增大而易吸引。此舉亦有 用而以發泡材作為刷子使用時較有形成小 毛、· B，亦不致如毛刷般因毛球過大而堵塞吸引孔 21 22。藉此，如第18A圖及第18B圖所示，以吸引噴嘴6之去 程動作之清掃，幾乎可吸引去除所有之塵埃，剩下非常難 吸引之塵埃則可以回程動作之清掃吸引去除，對所有塵埃 可發揮高清掃性能《即使為過濾網4之垂直部份，由於去程 動作之毛球小，而不致掉落，保持於過濾網4,而於回程動 作時清掃。 如第19圖所示，若於發泡矽刷3〇兩側各設置丨個吸引孔 22A、22B，可在去程動作去除所有塵埃，而更理想。 發泡材亦可使用如EPT(乙丙橡膠)般材質，從連含油脂 之塵埃亦不致附著於表面或對磨損之耐久性優異之面而言 使用矽最佳。發泡材中，矽強度優異，而可防止清掃時與 過濾網4之摩擦造成之破損。又，由於發泡材將塵埃如包住 般捕集，故不致如毛刷般，將塵埃擠壓至過濾網4之對側（熱 交換器側）。進一步，由於發泡材柔軟，故清掃時，幾乎無 與過濾網4摩擦之聲音，而可謀求清掃時之靜音化。在本實 施形態中，從比較評價之實驗，發泡矽刷30使用使清掃性 最佳之發泡率為4倍者。 第4實施形態 第20A圖及第20B圖顯示本發明第4實施形態之過濾裝 置56之吸引喷嘴之構造，在傳動帶2〇表面，於吸引孔2〇旁 邊固定截面呈梯形且如海綿或EPT(乙丙橡膠）般之發泡材 構成之刷子32，藉傳動帶2〇之驅動，刷子32之位置亦可與 吸引孔22—同變更。 在此’刷子32與過濾網4接觸之一側之寬度w考慮清掃 性能與驅動時之阻力而設定，且刷子32之高度H考慮過濾網

Field of the Invention The present invention relates to an air conditioner having a function of automatically cleaning an air filter provided in an air inlet of an indoor unit. [Prior Art 3] The filter device of the conventional air conditioner is provided with an air filter for preventing dust from entering the inside of the air conditioner body in front of the heat exchanger, and the air filter 10 is detachably configured to clean the attached dust by hand. The filter device thus constructed requires not only frequent maintenance, but also until the air filter is gradually clogged with dust until the maintenance is performed. As a result, the air volume passing through the heat exchanger is lowered, and the air-conditioning capability is lowered, resulting in an increase in power consumption. Therefore, for the purpose of reducing the maintenance time of the air filter, a filter device that sweeps and cleans the filter attached to the air filter or sucks and cleans the filter attached to the air filter with a nozzle is provided (for example, refer to Patent Document 1) Or patent document 2). [Patent Document 1] Japanese Patent Laid-Open Publication No. Hei 6-74521 Patent Document 2: Japanese Patent Laid-Open Publication No. 2002-340395 No. Since the brush is swept away and cleaned, dust is attached to the brush, and it is necessary to deal with the damage caused by the sweeping, and the sound during cleaning can be reduced. Further, when a large number of voids are provided in the sheet, since the suction-swept wind can leak from the gap to attract dust and prevent the dust from falling, the sheet can be used to separate and attract the dust by the high-definition performance. Further, since the sheet portion of the curved portion can be smoothly driven, damage can be prevented and reliability can be improved. In particular, when the plurality of sheets are disposed so that the gaps do not overlap, the cleaning performance of the portion located in the sheet gap can be prevented from being lowered. When a foamed material is used as the dust separating member, in addition to preventing dust from being attached, since the dust adhering to the filter is also removed by the deformation of the foamed material for cleaning, higher cleaning performance can be obtained. It can also reduce the friction sound of the filter and the filter. Further, when ruthenium is used for the foamed material, it is possible to prevent breakage of the foamed material due to friction between the squeegee and the filter screen, and high reliability can be obtained. Further, when the length of the belt side of the cross-sectional shape of the foamed material is made longer than the length of the side of the filter, the high-definition sweep performance can be maintained for a long time, and the dust can be efficiently removed from the filter. Moreover, since the durability against the bending property of the foamed material is improved, maintenance is not required. Further, when the dust-cutting member is formed of the sheet which is provided on the side surface of the left and right of the foamed material, the durability of the repeated bending in the right and left driving directions can be improved, and when the sheet is made of a non-woven fabric or a resin film, The foam material is bonded to the ease of deformation of the foamed material and the ease of deformation during deformation.冨 When the sheet is set to be shorter than the foamed material on the side of the left and right sides of the rattan, the dust-removing property of the filter 8 8 net, the durability of repeated bending of the right and left drive directions, and the ease of deformation and deformation are improved.

I: Embodiment 3 Best Mode for Carrying Out the Invention Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 10 is a cross-sectional view of an indoor unit of the air conditioner of the present invention. The indoor unit body 50 houses a heat exchanger 52 therein, passes through the heat exchanger 52, and is heated by the heat exchanger 52 after being sucked into the indoor air. The fan 54 that blows air into the room and the filter device 56 disposed upstream of the heat exchanger 52, by the action of the fan 54, draws in a plurality of 15 inhaled air formed from the front to the top of the body 50, and floats in the air. It is removed by a filtering device 56 disposed between the suction port and the heat exchanger 52. Fig. 2 is a view showing the entire configuration of a filter unit 56 of the air conditioner of the present invention. As shown in Fig. 2, the filter for removing the dust 20 passing through the air of the heat exchanger 52 is provided with a filter frame 2, a filter screen for holding the filter frame, and a suction nozzle which slides freely along the surface of the filter 4. 6. The suction nozzle 6 is placed on the upper and lower ends of the filter frame 2 by the pair of guides 8, and is kept at a certain distance from the filter screen 4 to smoothly move left and right. Further, one end of the suction duct 10 is connected to the suction nozzle 6, and the other end of the suction duct 10 is coupled to the suction unit 11 of the suction 11 1351495. The suction duct 10 forms a bendable duct which does not interfere with the movement of the suction nozzle 6. Further, the suction duct 12 is coupled to the exhaust duct 14 and guided to the outside. The dust adhering to the filter 4 is sucked from the suction nozzle 6, and is discharged to the outside through the suction duct 10, the suction device 12, and the exhaust duct 14. (5) When the filter unit 56 is housed in a small-sized household air conditioner, it is necessary to reduce the size and output of the suction device. Therefore, it is necessary to use a small air volume to exert a strong attraction force, and the suction nozzle 6 is used to concentrate the suction. In part, in order to enhance the attractiveness, the position of the suction position of the filter 4 is cleaned by switching its position. 10th and 3rd, the structure of the suction nozzle 6 of the first embodiment is shown, and the long nozzle-like opening 18 for the entire length of the filter 4 is provided in the suction nozzle body 16, and further, The belt 20 driven along the opening portion 18 is provided with a suction hole 22 so as to be attracted only from one of the openings 18, and the 15 belt 20 can be driven to change the place to be attracted. Since the belt 20 is attracted to the nozzle body 16, it can be guided by the belt guiding body 24 formed by the body of the suction nozzle body 16 by fusion or the like, and the belt 20 can be guided while being restrained outside the suction hole 22. Some of them create situations that attract leaks. With this configuration, since the small suction holes 22 can be concentrated by a small amount of air, the air velocity of the air passing through the suction holes 22 is increased, and even a small suction device can exert a strong attraction. Further, on the surface of the transmission belt 20, a sheet brush 26 that functions as a dust separating member that separates the dust adhering to the filter screen 4 from the filter screen 4 is fixed to the suction hole 22 by the sheet, and driven by the belt 20, the sheet brush 26 is driven. The position 12 8 can also be changed with the attraction hole 22 - the same. If the driving device for changing the suction position and the brush position needs only the driving device of the driving belt 20 for this structure, the structure is simple and can be realized at low cost, so that the positions of the suction hole 22 and the sheet brush 26 can be constantly maintained. relationship. 5 As shown in Fig. 4, the filter 4 is completely cleaned by the drive belt 20 that drives the suction nozzle 6, and the position of the suction hole 20 and the sheet brush 26 is changed, and the suction nozzle 6 is driven to the left and right along the filter screen 4 so that the suction hole 22 and the suction hole 22 are The sheet brush 26 is repeatedly performed by performing the back and forth motion indicated by the arrow in the figure. The suction hole 22 and the sheet brush 26 are set to be about 1/4 of the length of the entire length of the filter, and the cleaning operation is repeated by the arrow shown by the arrow in the figure. Further, the height hi of the sheet brush 26 shown in Fig. 3B is designed in accordance with the distance from the filter 4. The distance between the filter 4 and the suction nozzle 6 is designed to be 1.5 mm at the center of the axial direction of the suction nozzle 6, and even if the filter 4 is bent (up to 1 mm), it is not in contact. Therefore, when the bending of the filter 4 is generated in the opposite direction to the suction nozzle 15, the suction nozzle 6 is at a maximum distance of 2.5 mm from the filter 4. Hi is set to 5.0 mm, and in this state, the sheet brush 26 can also completely contact the filter 4. The sheet brush 26 is fixed to the belt 20 by using an adhesive or the like, and when it is cleaned, it is strongly followed by the friction of the filter 4. Therefore, in the present embodiment, the sheet brush 26 has an L-shaped sheet and a portion larger than the portion of the belt 20 to strengthen the fixing force. When this shape is used, since the portion which is shaped into an L shape is liable to be reversed toward the direction of the belt 20, it is supported by the belt guide 24 to maintain the [shape state. Since the L-shaped shape is useful for the subsequent area, it may be an inverted T-shape or other shapes similar thereto. In the household small air conditioner, since the filter 4 is located on the top surface and the front surface of (?) 13 1351495, as shown in Fig. 2, the suction nozzle 6 has a bent shape. Therefore, although the sheet brush 26 is also bent by the driving position of the belt 20, since the sheet is relatively thin, the curved portion can be formed into a wave shape and can be driven without problems. Further, in Fig. 3A, the curved portion of the sheet brush is not shown as a waveform. Since the transmission belt 20 and the sheet brush 26 require tensile strength and durability against abrasion, and also require flexibility for bending, a rubber or resin film is preferably used as the material. In particular, a resin film in which the resin film is PET (polyethylene terephthalate) or PEN (polyethylene naphthalate) is excellent in strength, flexibility, and durability, and can be made from mechanical strength. The belt 20 is as thin as about 75 to 100 μm, so that the suction nozzle 6 can also be formed into a thin shape to improve the storability. As a result, the indoor unit body can be made thinner, which is also preferable from the viewpoint of design. In terms of cost, material and processing costs are also extremely low. When the sheet brush 26 is made of rubber according to the characteristics of the material, a thickness of 0.5 to 1.0 mm is used, and when a resin film is used, a thickness of about 50 to 75 μm is used. 15 Fig. 5 is an enlarged view of a part of the sheet brush 26 (part B of Fig. 3A), showing the state before and after the processing, as can be clearly seen from Fig. 5, the sheet brush 26 can be fixed very simply. Drive belt 20. In particular, when both the power transmission belt 20 and the sheet brush 26 use a resin film, since it can be melted (hot-melt or ultrasonically fused), it can be strongly fixed by fixing with an adhesive. 20 The operation and action of the filter device 56 configured as described above will be described below. First, the state of the brush and dust when the brush is used will be described. Figs. 6A and 6B show the construction of the suction nozzle using the brush, and on the surface of the belt 20, the brush 28 is fixed beside the suction hole 22. Since the brush 28 has the function of dropping the dust adhering to the filter 4, the dust which cannot be cleaned by the suction of the filter 4 can be sucked and cleaned. More than 28 brushes are used for the brush. The brush 28 is driven by the belt 2 to change position with the suction hole 22, and is often present beside the suction hole 22, and the dust dropped by the brush 28 is sucked from the suction hole 22. However, in the suction nozzle 6 using the brush 28, as the number of times of cleaning of the filter 4 is increased, the dust adheres to the brush 28, and the cleaning performance of the filter device is lowered, and the maintenance of the brush 28 is periodically performed. Fig. 7 is a view showing an example of a suction nozzle at the time of cleaning the suction nozzle when the brush 28 is used. The solid arrow indicates the wind of attraction, and the reverse arrow indicates the direction of travel of the suction nozzle 6 during the outward movement. The brush 28 is attached to the rear of the suction hole with respect to the cleaning direction of the outward movement of the suction nozzle 6. The white circle indicates dust which is easily attracted by dry dust, and the black circle indicates dust which is hard to attract due to strong adhesion to the filter 4 such as grease or cigarette oil. When cleaning, the dust that is easily attracted is attracted before the contact with the brush 28, and the dust that is not easily attracted is attracted by the brush 28. At this time, as shown in the figure, dust which is not easily attracted by grease or the like adheres to the surface of the brush 28 in a large amount, that is, as the cleaning increases, a lot of dust enters the inside of the brush 28, and the brush 28 is in a rather dirty state. . As a result, not only the cleaning performance of the filter device is lowered, but also when the dust adhering to the brush 28 is greatly grown and dropped, the possibility of blocking the suction hole by attracting the dust is greatly increased. Further, since the dust is contaminated by the bacteria, the sheet brush 26 used for the suction nozzle 6 of the present embodiment is used to solve the problem inherent in the brush 28, and the suction nozzle 6 which does not cause dust adhesion is realized. Fig. 8 is a cross-sectional view of the suction nozzle at the time of cleaning in the present embodiment. The state of the suction nozzle 6 and the over-twisting net 4 at the time of suction cleaning is viewed in a cross section. Arrows, circles, and the like in Fig. 8 indicate the same as in Fig. 7. Fig. 8 is a view showing the portion of the drawing 3 in Fig. 3A, that is, the α·Α cross-section state. Since the suction hole 22 is located in front of the sheet brush 26, the dried dust or the like is dropped from the filter web due to the attraction force, and is sucked and removed. The dust which cannot be removed by the attraction and the like by the attraction is the soft deformation of the sheet brush 26 after the suction hole 22 passes, and the surface is pressed against the surface of the filter 4, and the surface of the filter 4 is wiped. Drop from the filter 4. The dust that has been thrown is attracted by the suction hole 22 located nearby, and is cleaned. By wiping the surface of the filter 4 to perform cleaning, the hair is bitten to the filter 4 on one side, and the force of cleaning the brush is small, and the motor that drives the suction nozzle 6 to the left and right also has a small output and a small size, and the temperature of the motor rises. The aspect of reliability is also beneficial. The small motor can be used to have the advantage of large degree of freedom on the design surface of the single 7C body. Since the brush is soft, the sheet brush 26 is deformed correspondingly even if the filter 4 is deformed or bent, so that the front end of the sheet brush 26 is closely attached to the filter screen 4 without any gap, so that the dust is lowered and the cleaning performance is high. Quite excellent. On the other hand, because of its softness, it does not push the dust out to the opposite side of the stencil 4 (the heat exchanger side also has the dust that is forced to fall off for the squeegee 26 to accumulate at the front end of the slap. When the dust accumulates to H degree, it touches "M. The brush is different from the brush, no dust is attached" and because the surface is smooth, the dust is not easily adhered. Even if it adheres to the surface, it rubs against the filter 4. Therefore, the cleaning performance can be maintained by using the sheet brush 26', and maintenance of the cleaning brush is not required. Second Embodiment 1351495 FIGS. 9A and 9B show the filter device 56 according to the second embodiment of the present invention. In the present embodiment, the point at which the plurality of slits are provided in the sheet brush 26A is different from that in the first embodiment. As shown in Figs. 9A and 9B, the slit enters 5 from the front end of the sheet brush 26A to the root portion (the belt 20) The side surface) 'cuts into a v-shaped shape to enter' and creates a gap in the portion of the slit. Figure 10 shows an enlarged view of a portion of the sheet brush 26A (part E of Figure 9A), showing before and after processing State, as shown in the figure The gap between the slits of the brush 2 6 A is 2 mm, and the size of the front end of each slit is cut into 10 V-shapes and is 1 mm. Since the filter 4 uses 40 meshes (40 mesh fibers in 1 inch) Therefore, the distance between the fibers of the filter 4 is 0.64 mm, and when the front end of the sheet brush 26A is 〇.64 mm or more, the sheet brush 26A can be prevented from entering the mesh of the net 4 and hooked to cause damage. In this embodiment, since the mesh spacing of the filter 4 is also different, it is also set to 1 mm from the edge. For example, the size of the 'sheet brush 26A (especially the size of the front end portion) should be designed to be larger than the filter. The spacing between the nets 4. If the mesh of the mesh is fine, the fine spacing of the slits of the sheet brush 26A may be smaller, and if the resin film such as 75 to 100 μm is used in the sheet brush 26A, from the viewpoint of tensile strength and the like The operation and action of the filter device 56 configured as described above will be described below. The role of the brush 26A as a function of dropping dust from the filter 4 is also described in the first embodiment. The action also has an effect on the brush 2 6 A wiping the transition net 4, and further, when the brush 26 When A returns to its original shape with elastic force, if the effect of dropping dust is used, a powerful drop-off capability can be obtained. 8 17 Figures 11A and 11B show the effect in a pattern diagram, the figure is During the cleaning, the blade 26A is the state in which the filter 4 is dragged, and the traveling direction of the (4) 2 pilot nozzle 6 is greatly deformed in the rear. The deformation amount is a large amount of dust or a strong dust adhered to the filter 4 of the filter 4. At the same time, the amount of deformation increases as the dust begins to accumulate at the front end of the sheet brush 26A. When the amount of deformation exceeds a certain value, the sheet brush 26A which is originally perpendicular to the surface of the belt 2 is elastic due to the elastic force. Return to the original state (vertical). In the state of Fig. 11B, in this case, the dust is dropped to the suction hole side and sucked and removed. Due to the strong force at this time, larger dust or dust can also be bounced off. When a plurality of slits are provided in the sheet brush 26A, the resulting sheets each frequently perform this operation, so that the ability to drop the dust can be greatly improved as compared with when the slit is not entered. Further, this effect is remarkable in physical properties particularly when a resin film of PET or PEN is used. Further, by providing a plurality of slits in the sheet brush 26A, the flexibility of the entire sheet brush can be increased. As a result, even if the filter 4 has a curved or uneven shape, the blade brush 26A can be contacted in accordance with the shape thereof, and even the corners can be cleaned. Further, when the plurality of slits are provided in the sheet brush 26A, there is a driving advantage in addition to the improvement of the cleaning performance. Fig. 12 is a schematic cross-sectional view showing the suction nozzle of the embodiment, which depicts only the suction nozzle body 16, the belt 20, the suction hole 22, and the sheet brush 26A of Fig. 9A. In order to clean the furnace, the net 4 is fully integrated, and the drive belt 2 is driven to change the position of the suction hole 22 as previously explained. In the present embodiment, "the plurality of small slits are provided by the sheet brush 26A. When the curved portion of the nozzle 6 is attracted, the sheets subdivided by the slits are superposed to form a curved portion, instead of being deformed as in the i-th embodiment. Waveforms are also available. Therefore, since the sheet brush 26A is not applied with excessive force, the deterioration and durability can be improved. In particular, by inserting the slit into the U shape as shown in the (10), the overlapping portion of the sheet brush 26A can be reduced, so that the deterioration of the sheet brush 26a is also reduced. Further, in the present embodiment, as described earlier, the slit is cut into a v-shape from the front end of the sheet brush 26A to the root portion (the surface of the belt side 2), and a gap can be formed, which contributes to the relative The suction holes are located on the opposite side of the sheet brush 26A to the vicinity of the sheet brush 26A. In the first embodiment, the sheet brush 26 obstructs the wind sucked from the suction hole 22, and the dust attraction force on the opposite side of the sheet brush 26A with respect to the suction hole 22 has no effect at all. In particular, when the filter 4 is vertical, if the dust of the sheet brush 26 is worn, it falls due to the attraction force, so that the indoor unit body is discriminated. However, when a plurality of slits are placed in the sheet brush 26A, and gaps are respectively provided in the slits, the suction wind can pass through the gaps, so that the dust passing through the sheet brushes 26A can also be sucked and cleaned. Fig. 13 is a schematic view showing the state in which the suction nozzle 6 of the present embodiment is cleaned, and the white arrow in the figure is the wind of attraction, and the size thereof indicates the strength of the wind. As can be seen from Fig. 13, on the opposite side of the sheet brush 26A, the wind passes through the gap. Further, it can be seen from Fig. 13 that the slit width of the sheet brush 26A is larger than the mesh width of the filter screen 4, so that the state of the mesh of the filter screen 4 is not caught. Further, when the plurality of slits are placed in the sheet brush 26A, a gap is provided, and the cleaning operation of the suction nozzle 6 shown in FIG. 4 is repeated. "Because the sheet brush 26A does not contact the filter 4, only the gap portion is cleaned. Performance is reduced. Therefore, as shown in the UA diagram and the 14B diagram, when a plurality of brushes 2 6 A having a gap are disposed adjacent to the suction hole 22 so that the gaps do not overlap, the sheet brush 26A contacts the filter screen by the back and forth movement of the suction nozzle 26. 4 comprehensive. At this time, since the suction wind also passes through the gap, the dust on the opposite side of the sheet brush 26A can also be sucked and cleaned. Further, in FIGS. 14A and 14B, the two sheet brushes 26A are disposed on one side of the suction hole 22, and as shown in FIGS. 15A and 15B, the two sheet brushes 26A are respectively disposed in the suction holes. 22 sides. In particular, in the latter case, the wind having the suction holes 22 is guided by the two brush 26A, and the two brush 26A can prevent the diffusion of the attracted wind, so that the suction wind speed on the surface of the high filter 4 can be increased. And improve cleaning performance. Third Embodiment FIG. 16A and FIG. 16B show a suction nozzle structure of a filter device 56 according to a third embodiment of the present invention. In the present embodiment, a foaming brush 30 for foaming a stone like a sponge is fixed to the belt 20 . The point is different from the above-described third embodiment. In Fig. 16B, the foaming brush 30 is designed to have a width 汜 of 5111111 and a height h2 of 5 mm. The width is determined by the cleaning performance and the resistance during driving, and also varies depending on the material. The height is designed to be 5.0 mm as described in the first embodiment, and the maximum distance between the filter 4 and the suction nozzle is 25 mm, and the cable is completely in contact with the filter. The status is normal. The action of the filter device 56 configured as above will be described below. Fig. 17 is a cross-sectional view showing the suction nozzle at the time of cleaning in the present embodiment, and the state in which the suction nozzle 6 and the filter 4 in the middle of sucking the cleaning filter 4 are viewed in a cross section. The solid arrow in the figure indicates the wind of attraction, and the white arrow indicates the direction in which the suction nozzle 6 moves back and forth. Further, the circle on the filter 4 1351495 circle marks the attached dust (the dust removed by the filter 4). White circles indicate dust that is easily attracted by dry dust, black circles indicate dust that is not easily attracted by micro-fat, and black triangles indicate dust that is very difficult to attract with many oils. The foaming brush 30 is attached to the rear of the suction hole 22 with respect to the direction in which the cleaning operation of the suction nozzle 6 is performed. Figure 17 shows the portion of the 16th image with the attraction hole, that is, the state of the F_F section. 10 15 20 In the course of cleaning, the suction hole 22 is located on the surface of the foaming brush 3, so that dry dust (white circles) or the like is pulled out from the filter 4 by suction and is sucked and removed. The dust (black circle) that cannot be removed by the attraction alone due to the oil and fat is a soft deformation of the foamed stone after the suction hole 22 passes, and the surface is tightly attached to the surface of the net 4 , wipe the surface of the net 4, and drop it from the _4. The dust that rides on the ground is attracted by the attraction of the hole 22 and is cleaned. However, dust (black triangles) containing a lot of grease which is very difficult to absorb cannot be removed by this and adhere to the filter 4. Such a miscellaneous use of a sponge-like foam material as a brush as shown in the enlarged view of Fig. 17, the foam material - the surface is soft and deformed, the surface enters the mesh of the mesh 4, such as wrapping the sticky The dust is collected as it is, and the surface is dialed. This effect is greatly exerted by the pores on the surface of the foamed material. The dust is collected by the surface of the stencil 4 and collected into a hair ball shape. The hair ball is brushed from the brush, and the hair ball that is plucked out is rubbed by the foam material, and is easily plucked from the filter 4 to form a hair ball to increase the surface area. Big and easy to attract. This is also useful. When the foamed material is used as a brush, it is more likely to form small hair, B, and does not block the suction hole 2122 due to excessive hairball. As a result, as shown in FIGS. 18A and 18B, the cleaning of the suction nozzle 6 can almost remove all the dust, and the dust that is very difficult to attract can be removed and removed by the returning operation. All the dust can play the high-definition sweep performance. Even if it is the vertical part of the filter 4, the hairball is small because it does not fall, and it stays in the filter 4, and it cleans in the returning action. As shown in Fig. 19, if one suction hole 22A, 22B is provided on each side of the foaming brush 3, it is preferable to remove all the dust in the outward movement. The foamed material can also be made of a material such as EPT (ethylene propylene rubber), which is best used from the surface where the grease containing grease does not adhere to the surface or is excellent in durability against abrasion. In the foamed material, the strength of the crucible is excellent, and the damage caused by the friction with the filter 4 at the time of cleaning can be prevented. Further, since the foamed material is trapped as if the dust is trapped, the dust is not pressed to the opposite side (the heat exchanger side) of the filter 4 as in the case of a brush. Further, since the foamed material is soft, there is almost no sound which is rubbed against the filter 4 during cleaning, and it is possible to achieve quietness during cleaning. In the present embodiment, from the comparative evaluation experiment, the foaming brush 30 was used to have an optimum foaming rate of 4 times. Fourth Embodiment FIG. 20A and FIG. 20B are views showing the structure of the suction nozzle of the filter device 56 according to the fourth embodiment of the present invention. The surface of the belt 2 is fixed in a trapezoidal shape like a sponge or EPT on the side of the suction hole 2〇. The brush 32 composed of a foamed material such as ethylene propylene rubber is driven by the belt 2, and the position of the brush 32 can be changed together with the suction hole 22. Here, the width w of one side of the contact between the brush 32 and the filter 4 is set in consideration of the cleaning performance and the resistance at the time of driving, and the height H of the brush 32 is set as the brush 32 and the filter 4 in consideration of the amount of bending of the filter 4. Fully in contact, in a state of micro-compression. The brush 32 is fixed to the belt 2 by using an adhesive or the like. When the cleaning is performed, slight deformation occurs between the brush 4 and the filter 4, and the filter 4 is continuously rubbed. Therefore, it is necessary to be strong and then not caused by repeated driving of the right and left. The peeling of the brush 32. Therefore, in the present embodiment, the brush 32 has a trapezoidal shape in cross section and is larger than the end surface of the belt 20 to enhance the fixing force. Here, the cross-sectional shape of the left and right directions of the brush 32 may be such that the length of the belt side is longer than the length of the filter side, and any shape can be 'in addition to the trapezoidal shape, for example, a trapezoidal shape and a rectangular cross-sectional shape are combined with the Other shapes similar to this can also be used. Fig. 21 is a cross-sectional view of the suction nozzle at the time of cleaning in the present embodiment. Fig. 2 is a state in which the suction nozzle 6 and the filter 4 in the middle of the cleaning filter 4 are sucked and viewed. Arrows, circles, and the like in the drawings are the same as those in the third embodiment (particularly Fig. 17), and therefore the description thereof will be omitted. Further, the operation and action of the suction nozzle 6 are also the same as in the third embodiment. Further, by using the squeegee material of the present embodiment, the dust containing the grease does not adhere to the surface of the brush, and the dust can be removed from the filter 4 to improve the cleaning performance and prevent the grease or the surrounding environment. Causes the deterioration of the brush' and improves the durability of wear or cracking. Further, the brush 32 composed of the foamed material of the present embodiment has a surface 32a which is in contact with the side of the filter 4 as shown in Fig. 22, and the side surfaces 32b and 32c on the left and right driving sides are smooth, so that the filter can be used. 4 dust pull-out and durability of repeated bending of the brush 1351495 sub-32. Namely, by making the brush 32 contact the surface 32a of the filter 4 to have a coarse thickness, it is possible to improve the dialing performance of dust containing a plurality of greases which are tightly adhered to the filter 4 and are not easily plucked. Further, by making the brush 32 smooth at least 5 degrees thicker than the side faces 32b and 32c in the left-right direction, the bending durability of the suction nozzle 6 can be improved by repeated iterations. (Fifth Embodiment) Fig. 23 is a view showing a structure of a suction nozzle of a filter device 56 according to a fifth embodiment of the present invention. Since the basic structure of the suction nozzle body is the same as that of the fourth embodiment, the description thereof will be omitted. In the present embodiment, unlike the fourth embodiment, as shown in Fig. 23, the brush 34 is constituted by a foam material and a sheet 38 provided on the side surface on the left and right driving sides. When the suction nozzle 6 is driven left and right, as shown in Fig. 23, the brush 34 is pressed against the filter 4, and one side of the friction filter 4' is deformed in the right direction or the left direction. At this time, a large stress is generated in the vicinity of the contact surface of the brush 34 and the belt 20, and cracking may occur in the vicinity of the foamed material 36 by repeated driving left and right. Therefore, by the side joining sheet 38 of the foamed material 36, the foamed material 36 can be reinforced to improve the bending durability and prevent the occurrence of cracks. Further, when the sheet 38 is joined to the foamed material 36 by using a non-woven fabric, the ease of deformation of the brush 34 can be maintained, and the durability against repeated bending of the brush 34 in the right and left driving directions can be improved. Further, when the resin film is used for the sheet 38, the contact resistance between the brush 34 and the transition net 4 can be reduced, the increase of the driving torque can be suppressed, and the ease of deformation of the brush 34 can be maintained, and the left and right driving of the brush 34 can be improved. Repeat the direction of the 24 bending durability. Further, as shown in Fig. 24, 'the length of the sheet 38A is set shorter than the foamed material 36 in the left and right driving side sections, and the contact resistance between the brush 34A and the over-twisted net 4 can be greatly reduced, and the increase of the driving torque can be further suppressed. . The sheet brush, the foaming brush, and the like according to the first to fifth embodiments are also useful in other filtering devices (for example, a cleaning device that only removes dust) that are not subjected to the suction cleaning method, and are not limited to the first to fifth embodiments. The form of the filter device described in the form. As described above, since the air conditioner of the present invention can be used for cleaning the filter screen by using the suction nozzle and the suction nozzle, the air filter of various shapes can be used for the air filter of various shapes or the air tearer used under the respective installation conditions. Therefore, not only the air filter of the air conditioner, but also an air filter such as a device for cooling the fan (for example, an air filter for stabilizing the power source) or a filter device for automatically cleaning the air filter such as a ventilating fan can be applied.
