201212869 ’六、發明說明： L發明戶斤屬之技術領域3 發明領域 本發明係有關於一種使用於旋風式電動吸塵器等之集 塵裝置及電動吸塵器。 t先前技術3 發明背景 近年來之旋風式電動吸塵器用的集塵裝置先使與塵埃 一同自吸入具吸引之空氣在圓筒集塵部内轉動。藉由該空 氣之轉動，利用離心力將混入空氣中之塵埃分離，並將已 經分離之塵埃收集到圓筒集塵部下方之集塵室。而且，塵 埃業經分離之空氣會被吸入到電動送風機之吸引側。又， ' 於圓筒集塵部之上方，過濾器組件插裝於設於集塵容器之 ' 過濾器插裝部，成為以該過濾器組件過濾且除去塵埃之構 成（參照如專利文獻1)。 專利文獻 【專利文獻1】曰本專利特開第2003-19095號公報 【發明内容】 發明概要 發明欲解決之課題 然而，上述之習知之集塵裝置的構成中，即使不將過 濾器組件插裝到過濾器插裝部，集塵容器也會原封不動地 組裝於吸塵器本體。因此，即使是在沒有過濾器組件之狀 態下，也可使吸塵器本體運轉。因此，會產生被吸引之塵 201212869 埃會通過沒有過濾器組件之集塵容器而被吸引，配置在電 動送風機正前方之過濾器構件則會產生異常阻塞的課題。 本發明係用以解決如此之習知之課題者，其目的在於 提供一種集塵裝置及電動吸塵器，該集塵裝置及電動吸塵 器係可在沒有過濾器組合構件之狀態下，不可能將集塵容 器組合到吸塵器本體而使吸塵器本體。藉由該構成，可防 止被吸引之塵埃在未被除去之狀態下通過集塵容器而被吸 引往吸塵器本體。 解決課題之手段 本發明之集塵裝置，包含有：塵箱本體，係於内部呈 同心狀配置有略圓筒狀之一次過濾器；旋風空間，係形成 於塵箱本體之内面與一次過濾器之外周面之間；塵埃蓄積 空間，係成略圓筒狀，且配置於旋風空間之下方，用以蓄 積業經分離之塵埃；二次過濾器，係配置於一次過濾器之 上部並且收集細塵；蓋體，係安裝於塵箱本體之上部；除 塵部，係配設於二次過濾器之上方，並且用以除去附著於 二次過濾器之細塵；及突起部，係形成於除塵部之一部份， 其中於蓋體與突起部相對之位置設有可自由出入之滑動 體。而且在相對於二次過濾器側之突起部之位置的蓋體 側，設置有可自由出入且自蓋體之外周下端朝蓋體之外周 方向突出之滑動體，故可安裝蓋體組合於塵箱本體之上部。 可是，若忘記裝設二次過濾器時，由於形成於配設於 二次過濾器上方之除塵部之一部分的突起部不抵接於滑動 體，因此滑動體會呈現保持在由蓋體之下端朝外周方向突 4 201212869 出。因此’滑動體會抵接於塵箱本體上端而蓋體無法安裝 於塵箱本體上部。由於無法在沒有二次過濾器之狀態下安 裝蓋體’因此集塵裝置無法設置於吸塵器本體。因此，由 於吸塵器本體無法運轉’故可防止被吸引之塵埃在未被除 去之狀態下通過集塵裝置而往吸塵器本體吸引之現象。 發明效果 本發明之集塵裝置係可防止蓄積於塵埃蓄積空間之塵 埃在未被除去之下即通過集塵裝置而被吸引往吸塵器本 體’或集塵裝置本身亦可為小型化，或可藉將該集塵裝置 裝載於電動吸塵器，而提供小型且使用方便性佳之電動吸 塵器。 圖式簡單說明 第1圖係本發明之實施形態1申之具有集塵裝置之電動 吸塵器的全體立體圖。

關於本發明之第1實施形態中之使用集塵裝置之電動 吸塵器，使用第1〜10圖說明。第1圖係本發明之實施形態 1中之具有集塵裝置之電動吸塵器的全體立體圖。第2圖係 本發明之實施形態1中之集塵裝置的前方立體圖。第3圖 係本發明之實施形態1中之集塵裝置之後方立體圖。第4 圖係顯示本發明之實施形態1中之集塵裝置之内部構成的 立體圖。第5圖係第3圖之B-B截面圖。第6圖係第2圖 之A-A截面圖。 本實施形態中之使用集塵裝置之電動吸塵器係如第1 圖所示，具有：吸塵器本體1、連接於設在吸塵器本體1前 方之吸入口 la的軟管2、設置於軟管2之前端之連接管3、 連接於連接管3之延長管4、設置於延長管4之前端且具有 用以吸引塵埃之開口部（未圖示）之吸入具5。 6 201212869 又，吸塵器本體1内設有用以吸引塵埃之電動送風機 6，並且裝設有可自由裝卸之用以集中塵埃之集塵裝置7。 本實施形態中之集塵裝置7之外廓係如第2圖、第3圖 所示，由塵箱本體8、覆蓋塵箱本體8之上面的蓋體11、 設置於蓋體11之把手10、用以封塞塵箱本體8下面之蓋子 9所構成。 蓋子9可利用設置於塵箱本體8之轉樞部13而可轉動 地安裝於塵箱本體8,並且利用鉤扣18卡止於塵箱本體8。 又，藉由安裝於蓋子9之墊圈D29，塵箱本體8與蓋子9 之間係密封的（保持氣密性）。 如第6圖所示，蓋子9係可藉轉動鉤扣18而解鎖，且 以轉樞部13為軸來開關之構成。當壓下推桿12時，滑動 件47會下降，藉此鉤扣18開啟，開放蓋子9。再者，如第 7圖〜第10圖所示，蓋體11藉扣件15與爪部14與塵箱本 體8卡合。 如第5圖所示，塵箱本體8内呈略同心狀地設有一次過 濾器21，且於一次過濾器21下方設置傘狀延伸部22。再 者，延伸部22藉由利用熔著或爪(未圖示）之嵌合等機構， 安裝於一次過濾器安裝框57。 一次過濾器21之上方設有形成為褶狀之二次過濾器 23，進而於其上方，具有如第6圖所示之利用振動等機構 使蓄積於二次過濾器23之塵埃掉落之除塵部24、或使除塵 部24振動之機構之馬達部25。 一次過濾器21係以金屬材料所構成，且係作成在金屬 201212869 表面部分不設置由樹脂等形成之凹凸形狀之構成，藉此使 渦旋流滑順地流動。藉由使渦旋流滑順地流動，可提高空 氣與塵埃之分離效率，並且發揮減輕塵埃等捲繞的效果。 再者，藉由在一次過濾器21的表面施行研磨處理，可提高 其效果，又藉由施行抗菌處理，可使一次過濾器21保持清 潔。 混有由吸入具5吸入之塵埃的空氣經由設置於吸塵器 本體1前方之吸入口 la，吸入到設置於第3圖所示之塵箱 本體8之吸氣口 B17。吸入到吸氣口 B17之空氣在第5圖 所示之一次過濾器21之外周與塵箱本體8所形成之旋風空 間31流動，並藉由於該處產生之渦漩流而進行離心分離成 以棉絮為主之塵埃與含有細塵之空氣。以棉絮為主之塵埃 會通過形成於延伸部22與塵箱本體8間之集塵通路32,而 漸往塵埃蓄積空間52蓄積。 其中，旋風空間31之寬度L1係大於集塵通路32之寬 度L2。而且塵埃蓄積空間52之内徑R4大於旋風空間之外 徑R3。而且，塵箱本體8具有配合延伸部22之形狀而擴 展開之傾斜部53。延伸部22之上端係位於較傾斜部53上 方的位置，又延伸部22的下端係位於較傾斜部53下方的 位置。 相較於旋風空間31之寬度L1，集塵通路32之寬度L2 較小，因此包含塵埃之空氣由旋風空間31往塵埃蓄積空間 52流入時，空氣的流速會加速。 而且，藉由業經在集塵通路32加速之空氣，由旋風空 8 201212869 =31朝向塵埃蓄積空間52產生壓附之力量，防止蓄積於 f埃蓄積^52之錢往旋W錢。再者，延伸 4 22之下端係作成位於較傾斜部53下方的位置 在傾斜部53亦可得到同樣的效果。 一疋〃 又，藉形成配合延伸部22之形狀之傾斜部$ =地進行由旋風”31往塵埃蓄積之空氣的流 又’延伸部22與塵箱本體8之傾斜部53由蓋子9側來 的話，係成為如於垂直上方形成頂壁 =塵埃蓄積空間52之以棉絮為主之塵埃變得心= 間31飛散，可提高集塵效率。 疋八二

之傘狀内部之塵埃量，因此使用者容易判斷丟棄垃圾的時 期。 再者，本實施形態中，延伸部22具有由其斜面58下端 朝垂直方向延伸之凸緣59。藉此，塵埃蓄積空間52内之塵 埃會被壓縮，可防止再返回旋風空間31，並且可提高集塵 性能。 在旋風空間31業已分離棉絮等之塵埃而含有細塵之空 氣會通過一次過濾器21，並且藉由二次過濾器23來過濾細 塵。接著，僅有不含有細塵之空氣通過二次過濾器23，並 且通過第3圖所示之吸氣口 A16,被吸引到電動送風機6。 堆積於二次過濾器23之細塵係當電動送風機6之運轉 停止時，藉馬達部25使設置於二次過濾器23上方之除塵 部24振動，而由二次過濾器23剝離。接著，已剝離之細 塵通過一次過濾器安裝框57更内側之空間，往在一次過濾 器21下方且設置於延伸部22之内側之内筒33蓄積。 為了將已剝離之細塵容易導往内筒33底部，内筒33之 上部係成為傾斜形狀。内筒33之内側設有折回處55，即使 將集塵裝置7之上下倒過來，可防止蓄積於内筒33之細塵 10 201212869 也會再次回到並再附著於二次過濾器23側。由於内筒33 與一次過濾器21連通，因此内筒33之已開口的下端可藉 由設置於蓋子9之墊圈E30而與塵埃蓄積空間52隔離。因 此，蓄積於塵埃蓄積空間52之塵埃不會進入一次過濾器23 之内側。 一次過濾器安裝框57之較一次過濾器21上方的徑比一 次過濾器之外徑R1大，且比形成旋風空間31之塵箱本體 8之外壁54之内徑R3小。 一次過濾器安裝框57由塵箱本體8之上方插入，以墊 圈B27與保持肋56壓接且予以保持。 二次過濾器23設置於一次過濾器21之上方，且於二次 過濾器23之外周分別安裝有墊圈A26與墊圈B27，墊圈 A26與墊圈B27對一次過濾器安裝框57分別發揮了防振及 密封之效果。二次過濾器23之外徑變得比一次過濾器21 之外徑R1大，成為可極力減少空氣的流通阻力之構成。因 此，塵箱本體8之上部外徑變得比旋風空間31之外壁54 的外徑（与R3)大。即塵箱本體8整體觀之係具有中間細之 形狀。 其次，說明二次過濾器23之除塵。如第5圖、第6圖 所示，除塵部24係藉由螺絲等的連結機構(未圖示）連結於 軌道41之蓋體11側的軸部43可自由裝卸地插入到二次過 濾器23側之除塵板44而連結除塵板44與軌道41之構成。 馬達部25係安裝於馬達40之轉動軸（未圖示）之曲軸37 係經由連桿38而與線性振盪子39連結，該等係被馬達蓋 201212869 體35與馬達殼體36包圍，藉由螺絲等的連結機構安裝於 殼體46。 馬達40與安裝於殼體46之電性基板49連接，配設於 電性基板49之電容器48藉由設置於吸塵器本體1側之充 電機構(未圖示）且經由第3圖所示之端子19進行充電。接 著，藉由開關34將蓄積於電容器48之電流放電使馬達40 轉動，線性振盪子39會振動。線性振盪子39連接於軌道 41，藉由將振動（如第5圖之箭頭所示之左右方向的振動） 傳達到除塵板44,可使二次過濾器23振動而使蓄積之細塵 剝離。 殼體4 6係藉由内壁4 5與螺絲等的連結機構而連結於蓋 體11，並可藉殼體46與設置於内壁45之軌道保持部42 挾持軌道41而予以保持。 在此，第7圖、第8圖、第9圖係顯示形成於除塵板 44之突起部60與滑動體61之構成及動作圖，且該除塵板 44係配設於二次過濾器23上方之除塵部24的一部份，滑 動體61係設置成由相對於突起部60之位置之蓋體11的外 周下端藉由線圈彈篑65之彈力而可自由出入地朝外周及垂 直下方向突出。 首先如第7圖所示，將爪部14插入至設置於塵箱本體 8之孔8a，漸漸傾斜可將蓋體11安裝於塵箱本體8之上部。 於是，形成於滑動體61之下端之凹部62抵接於形成在除 塵板44之突起部60，並且突起部60會插入到凹部62。滑 動體61抵接突起部60，並且形成於滑動體61之兩側面之 12 201212869 轴63沿著設置於蓋體11之導引溝64而可確實地開始移動。 其次，如第8圖所示，藉滑動體61之凹部62抵接於突 起部60,由蓋體11之外周下端朝外周及垂直下方向突出之 滑動體61施予推力至線圈彈簧65使之壓縮，然後朝内周 及垂直上方向移動而漸漸進入蓋體11之内周部。最後，如 第9圖所示，滑動體61收納於蓋體11之内周部，藉將扣 件15卡合於塵箱本體8,蓋體11安裝於塵箱本體8之上部。 而且，於上述滑動體61之下端形成有與突起部60相對 之凹部62，且突起部60係形成於為除塵部24之一部份之 除塵板44。因此，將蓋體11安裝於塵箱本體8上部時，突 起部60變得容易插入至由蓋體11之外周下端朝外周及垂 直下方向突出之滑動體61之凹部62，並可輕易地將蓋體 11安裝於塵箱本體8之上部。 又，藉滑動體61之凹部62抵接於突起部60，滑動體 61移動到内周及垂直上方向且進入時，滑動體61之凹部 62與除塵部24之突起部60也會咬合而不會位置偏移。又， 要使滑動體61由蓋體11之外周下端朝外周及垂直下方向 突出並且自由出入，可藉使用線圈彈簧65等之彈性體簡單 且便宜地構成。 又，形成於上述滑動體61之兩側面之軸63被設置於蓋 體11之導引溝64挾持，滑動體61之凹部62抵接於突起 部60,藉此滑動體61朝内周及垂直上方向移動而進入時， 形成於滑動體61之兩側面之軸63也確實地沿著設置於蓋 體11之導引溝64移動，不會有位置偏移。 13 201212869 而且，如第10圖所示，若在此忘記將二次過濾器23安 裝於塵箱本體8時，形成於為配設在二次過濾器23上方之 除塵部24之一部份的除塵板44之突起部60不抵接於滑動 體61。因此，滑動體61保持由蓋體11之下端朝外周及垂 直下方向突出，且滑動體61會抵接於塵箱本體8之上端， 或者滑動體61抵接於一次過濾器安裝框57上端，而蓋體 11無法安裝於塵箱本體8上部。 其中，若將滑動體61之凹部62的部分往上方上推的 話，滑動體61會如上述所示，形成於滑動體61之兩側面 之軸63漸漸沿著設置於蓋體11之導引溝64而朝内周及垂 直上方向移動。可是，在未將凹部62之部分上推之狀態下， 滑動體61不會動，而滑動體61抵接於塵箱本體8之上端 或者抵接於一次過濾器安裝框57之上端而無法將蓋體11 安裝於塵箱本體8之上部。因此，在沒有二次過濾器23之 狀態下，無法將集塵裝置7裝設於吸塵器本體1。而且，也 不可能使吸塵器本體1運轉，可防止被吸引之塵埃在未被 除去之狀態下，通過集塵裝置7往吸塵器本體1被吸引。 再者，上述實施形態中，係以設置成滑動體61由蓋體 11之外周下端朝外周及垂直下方向自由出入地突出之情況 來作說明，但是即使係設置成由蓋體11之外周下端朝外周 方向自由出入地突出之情況，作用或效果也相同。 本發明係包含有：塵箱本體，係略圓筒狀之一次過濾器 呈同心狀配置於内部;旋風空間，係形成於塵箱本體之内面 與一次過濾器之外周面之間；塵埃蓄積空間，係成略圓筒 14 201212869 狀，且配置於旋風空間之下方，用以蓄積業經分離之塵埃； 二次過濾器，係配置於一次過濾器之上部並且收集細塵；蓋 體，係安裝於塵箱本體之上部；除塵部，係配設於二次過濾 器之上方，並且用以除去附著於二次過濾器之細塵；及突起 部，係形成於除塵部之一部份，其中於蓋體與突起部相對 之位置設有可自由出入之滑動體，且該滑動體係自蓋體之 外周下端朝蓋體之外周方向突出，並且藉由與突起部之抵 接，朝蓋體之内周方向移動。 藉滑動體抵接於形成於除塵部之一部分之突起部，由蓋 體之外周下端朝外周方向突出之滑動體會進入内周方向， 因此可安裝蓋體而設置於塵箱本體之上部。 可是，若忘記裝設二次過濾器時，由於形成於配設於二 次過濾器上方之除塵部之一部分的突起部不抵接於滑動 體，因此滑動體會呈現保持在由蓋體之下端朝外周方向突 出。因此，滑動體會抵接於塵箱本體上端而蓋體無法安裝 於塵箱本體上部。 如此，由於無法在沒有二次過濾器之狀態下安裝蓋體， 因此集塵裝置無法設置於吸塵器本體。因此，由於吸塵器 本體無法運轉，故可防止被吸引之塵埃在未被除去之狀態 下通過集塵裝置而往吸塵器本體吸引之現象。 本發明係將該滑動體設置成可自蓋體之外周下端朝外 周方向突出且自由出入，並且可自蓋體之外周下端朝垂直 下方向突出而自由出入，由於滑動體抵接於形成於除塵部 之一部分之突起部，藉此由蓋體之外周下端朝外周及垂直 15 201212869 下方向突出之滑動體朝内周方向及垂直上方向移動，因此 可將蓋體安裝於塵箱本體之上部來組合。 可是，若忘記裝設二次過濾器時，由於形成於配設在二 次過濾器上方之除塵部的一部分之突起部不抵接於滑動 體，因此滑動體會保持由蓋體之下端朝外周及垂直下方向 突出。因此，滑動體會抵接於塵箱本體上端而蓋體無法安 裝於塵箱本體上部，在沒有二次過濾器之狀態下，不可能 將集塵裝置組合於吸塵器本體而使吸塵器本體運轉。因 此，可防止在被吸引之塵埃未被除去之下即通過集塵裝置 而被吸引往吸塵器本體。 本發明係於滑動體之下端形成與突起部相對之凹部，在 將蓋體安裝於塵箱本體上部時，形成於除塵部之一部分之 突起部容易插入到由蓋體之外周下端朝外周及垂直下方向 突出之滑動體的凹部，因此可容易地將蓋體安裝於塵箱本 體上部。 又，藉滑動體之凹部抵接於形成於除塵部之一部分之突 起部，由蓋體之外周下端朝外周及垂直下方向突出之滑動 體朝内周及垂直上方向移動而進入時，滑動體之凹部與除 塵部之突起部會咬合而不會位置偏移。 本發明係設有可賦與滑動體由蓋體之外周下端朝外周 方向或、外周及垂直下方向突出之勢能之彈性體，且藉線 圈彈簧等之彈性體，可簡單且便宜地構成。 本發明係將軸形成於滑動體之兩側面，並且利用設置於 蓋體之導引溝挾持軸者，藉滑動體之凹部抵接於形成於除 16 201212869 塵部之一部分之突起部’滑動體在朝内周及垂直上方向移 動而進入時’形成於滑動體之兩側面的軸會沿著設置於蓋 體之導引溝而確實地移動，不會位置偏移。 又，本發明之電動吸塵器係具有上述之集塵裝置者，可 提供使用方便性佳之電動吸塵器。 産業上之可利用性 如以上所述，本發明之集塵裝置係根據旋風式分離之原 理來収集塵埃之集塵裝置，可防止蓄積於塵埃蓄積空間之 塵埃在未被除去之下就通過集塵裝置，因此適用於家庭用 或業務用之電動吸塵器等。 【圖式簡單說明】 第1圖係本發明之實施形態1中之具有集塵裝置之電動

device and an electric vacuum cleaner for use in a cyclone type electric vacuum cleaner or the like. BACKGROUND OF THE INVENTION In the recent years, the dust collecting device for a cyclone type vacuum cleaner first rotates the air sucked from the suction device together with the dust in the cylindrical dust collecting portion. By the rotation of the air, the dust mixed in the air is separated by centrifugal force, and the separated dust is collected into the dust collecting chamber below the cylinder dust collecting portion. Moreover, the separated air of the dust is sucked into the suction side of the electric blower. In addition, the filter assembly is inserted into the filter insertion portion of the dust collecting container, and is filtered by the filter unit to remove dust (see Patent Document 1). . [Patent Document 1] Japanese Laid-Open Patent Publication No. 2003-19095 SUMMARY OF INVENTION Technical Problem However, in the configuration of the above-described conventional dust collecting device, even if the filter assembly is not inserted In the filter insertion portion, the dust collecting container is also assembled to the cleaner body as it is. Therefore, the cleaner body can be operated even in the absence of the filter assembly. Therefore, the attracted dust will be attracted to the dust collecting container without the filter unit. The filter member disposed in front of the electric blower will cause abnormal blockage. The present invention has been made to solve such a problem, and an object thereof is to provide a dust collecting device and an electric vacuum cleaner which are capable of disposing a dust collecting container without a filter assembly member. The vacuum cleaner body is assembled to the cleaner body. According to this configuration, it is possible to prevent the sucked dust from being sucked into the cleaner body through the dust collecting container without being removed.

The primary filter 21 is made of a metal material, and is formed such that the surface of the metal 201212869 is not provided with a concavo-convex shape formed of a resin or the like, whereby the vortex flow smoothly flows. By smoothly flowing the vortex flow, the efficiency of separation of air and dust can be improved, and the effect of winding up dust or the like can be exhibited. Further, by performing the polishing treatment on the surface of the primary filter 21, the effect can be improved, and by performing the antibacterial treatment, the primary filter 21 can be kept clean. The air mixed with the dust sucked by the suction device 5 is sucked into the air inlet B17 provided in the dust box body 8 shown in Fig. 3 via the suction port la provided in front of the cleaner body 1. The air sucked into the suction port B17 flows in the outer space of the primary filter 21 shown in Fig. 5 and the cyclone space 31 formed by the dust box body 8, and is centrifugally separated by the vortex flow generated there. Dust-based dust and air containing fine dust. The dust mainly composed of the batt is gradually accumulated in the dust accumulating space 52 through the dust collecting passage 32 formed between the extending portion 22 and the dust box body 8. The width L1 of the cyclone space 31 is greater than the width L2 of the dust collecting passage 32. Further, the inner diameter R4 of the dust accumulating space 52 is larger than the outer diameter R3 of the cyclone space. Further, the dust box body 8 has an inclined portion 53 which is expanded in conformity with the shape of the extending portion 22. The upper end of the extending portion 22 is located above the inclined portion 53, and the lower end of the extending portion 22 is located below the inclined portion 53. The width L2 of the dust collecting passage 32 is smaller than the width L1 of the cyclone space 31. Therefore, when the air containing dust flows from the cyclone space 31 into the dust accumulating space 52, the flow velocity of the air is accelerated. Further, by the air which is accelerated by the dust collecting passage 32, the force of the pressing is generated by the cyclone air 8 201212869 = 31 toward the dust accumulating space 52, and the money accumulated in the accumulating amount of the accumulating 52 is prevented from being swung.
