【明戶斤屬椅々貝J 發明領域 本發明係有關於一種用以將衣物脫水之脫水裝置。FIELD OF THE INVENTION The present invention relates to a dewatering apparatus for dehydrating laundry.
L· J 背景技術說明 典型脫水裝置’包含有用以將衣物脫水之脫水槽。脫 水槽一般具有：内槽’係旋轉用以將前述衣物脫水者；及 外槽’係收納該内槽者。内槽之周壁形成有多數透孔。自 衣物脫水去除之水，通過透孔從内槽排出。外槽承接自内 槽排出之水。 將接受脫水處理之衣物，由於含水，所以較重。藉内 槽之旋轉，衣物與内槽之周壁碰撞，因此，促使達到脫水 目的。另一方面，衣物與内槽周壁之間之碰撞，會引起脫 水槽之振動。 既有之各種脫水裝置’包含有檢測脫水槽之大振幅之 切換元件(例如參照曰本專利公開公報平6_282號、日本專利 公開公報平3-70593號、日本專利公開公報平3-70594號、曰 本專利公開公報平3-70595號、日本專利公開公報平3-70596 號、曰本專利公開公報平3-77584號、曰本專利公開公報平 3-289998號）。當脫水槽大幅位移時，切換元件作動且内槽 停止旋轉。 另外既有之脫水裝置，使用加速度感測器取代切換元 件，以檢測脫水槽之振動（例如參照日本專利公開公報平 201239150 5-237290號、日本專利公開公報平1〇 43469號）。加速产感 測器可檢測切換it件難以檢測之高速旋轉時之脫水^振 動。 脫水槽中衣物之分布隨機變動。因此，由於衣物分布， 前述加速度感測器和切換元件無法即刻檢測振動。 【發明内容】 發明概要 本發明目的在於提供一種可即刻檢測脫水槽之振動之 脫水裝置。 本發明一實施態樣之脫水裝置，包含有：脫水槽，係 旋轉動作以將衣物脫水者；感測器單元，係輸出包括關於 該脫水槽之振動之資訊之檢測訊號者；及控制裝置，係依 前述檢測訊號’控制前述脫水槽者，並且，前述感測器單 元具有：第1感測器元件，係檢測前述脫水槽之第1方向之 振幅者；及第2感測器元件，係相對前述第1感測器元件， 配設在與前述第1方向相反之第2方向者。 本發明之脫水裝置可即刻檢測脫水槽之振動。 圖式簡單說明 第1圖係例示作為脫水裝置一實施態樣之洗衣機之概 略縱截面圖。 第2圖係第1圖所示洗衣機之下部殼體之概略展開立體 圖。 第3圖係第1圖所示洗衣機之上部殼體之概略立體圖。 第4圖係第3圖所示上部殼體之概略展開立體圖。 201239150 第5圖係第1圖所示洗衣機之處理槽之概略展開立體 圖。

1圖所示’上部殼體130更具有閉塞開口部138之蓋體139。 蓋體139安裝成可相對頂壁131上下旋動。使用者可將蓋體 139朝上方旋動，以將衣物朝處理槽2〇〇投入。或者，使用 者可將蓋體139朝上方旋動，以將衣物自處理槽2〇〇取出。 第4圖係顯示安裝於上部殼體13〇之各種單元之概略展 開立體圖。利用第1圖、第2圖及第4圖來說明安裝於上部殼 體130之單元。 洗衣機100包含有機械式切換元件152，該機械式切換 元件152作為檢測處理槽200之振動之感測器單元之用。與 控制裝置150電連接之切換元件152 ’輸出包括關於該處理 槽200之振動之資訊之檢測訊號。控制裝置15〇依來自切換 元件152之檢測訊號，控制處理槽2〇〇。 洗衣機100更包含有支持切換元件152之支持片140。支 持片140沿上部殼體130之上背面壁133固定。安裝在支持片 140之左端之切換元件152，朝下方突出，且進入下部殼體 120之背面壁123及左壁125之間之角落部。 切換元件152具有：朝下方延伸之桿部153 ;及依桿部 153之姿勢而產生及輸出檢測訊號之訊號產生部154。處理 槽200若朝背面壁123及左壁Π5之間之角落部大幅位移，則 如第4圖所示’桿部153會朝背面壁123(及上背面壁133)旋 動。此時，訊號產生部154產生及輸出用以停止（或減速)處 理槽200旋轉之檢測訊號。以下說明中，朝背面壁123及左 壁125之間之角落部之方向’稱為第1方向fd。又，與第j 方向FD相反之方向’稱為第2方向SD。本實施陣、樣中，士刀 7 201239150 換元件15 2例示作為第1感測器元件。 第5圖係處理槽200之概略展開立體圖。利用第1圖至第 3圖及第5圖來說明處理槽200。 處理槽200具有：旋轉用以將衣物脫水之内槽210 ;及 收納該内槽210之外槽220。使用者可開啟上部殼體130之蓋 體139，以將衣物收納到内槽210。 内槽210具有：略圆筒狀周壁211 ;及連接周壁211之下 端之底壁212。周壁211形成有多數透孔213。自衣物脫水去 除之水，通過透孔213從内槽210排出。外槽220承接自透孔 213排出之水。 外槽220具有：略圓筒狀周壁221 ;及連接周壁221之底 壁222。周壁221具有：安裝底壁222之下緣223 ;及位在與 下緣223相反側之上緣224。本實施態樣中，下緣223例示作 為第1緣，且上緣224例示作為第2緣。 如第1圖所示，底壁222形成有開口部225。自衣物脫水 去除之水，通過開口部225從外槽220排出。洗衣機100更包 含有：與開口部225連接之連接導管226 ;及用以將水排出 至殼體110外之排水系統300。 如第2圖所示’基座部122具有：與側壁部121之背面壁 123略齊平之下背面壁143 ;與側壁部121之正面壁124略齊 平之下正面壁144;與側壁部121之左壁125略齊平之下左壁 145 ;及與側壁部121之右壁126略齊平之下右壁146。下背 面壁143形成有排水口 142。 如第1圖所示，排水系統300具有：排水管31〇，係具有 201239150 連接連接導管226之第1端部311，及與排水口 142連接之第2 端部312者；及排水閥320 ’係在控制裝置15〇控制下，開關 排水管310者。當排水閥320開啟排水管31〇時，外槽220中 之水會通過排水管310而排出到殼體110外。 如第1圖及第5圖所示’處理槽200具有略圓盤狀迴轉盤 230。迴轉盤230具有：橫跨在内槽210之底壁212上之圓板 部231 ;及自圓板部231之周緣朝上方突出之傾斜環232。傾 斜環232朝上方擴展。迴轉盤230更具有自圓板部231及傾斜 環232之上面突出之攪拌肋件233。攪拌肋件233放射狀地延 伸。迴轉盤230在洗淨衣物期間及/或使衣物乾燥期間旋 轉。因此，在前述步驟過程時，便適切地攪拌衣物。 洗衣機100更包含有：驅動機構400，係在控制裝置150 控制下，選擇性地使内槽210及迴轉盤230旋轉者^驅動機 構400具有：驅動馬達410，係產生使内槽210或迴轉盤230 旋轉之驅動力者；第1軸420，係與内槽210連接者；第2軸 430 ’係與迴轉盤230連接者；及離合裝置440，係將驅動馬 達410之驅動力傳送在第1軸420與第2軸430之間切換者。在 控制裝置150控制下動作之驅動馬達410及離合裝置440，固 定在外槽220之底壁222。第1軸420貫通外槽220之底壁 222，且與内槽210之底壁212連接。與第1轴420同心旋轉之 第2轴430 ’自第1轴420突出，且與内槽210之迴轉盤23〇連 接。本實施態樣中，驅動馬達41〇例示作為驅動源。 當用以洗淨衣物之洗淨步驟時，離合裝置440切換驅動 力之傳送路徑，使驅動力朝第2軸430傳送。於是，在洗淨 201239150 步驟時’迴轉盤230在内槽210内旋轉。 如第1圖所示，洗衣機100更包含有將洗淨衣物所用之 水朝處理槽200供給之供水系統500。供水系統5〇〇具有：供 水部510,係安裝在形成於上部殼體13〇之頂壁131之供水口 501(參照第3圖）者；切換閥520,係切換由供水部51〇供給之 水之路徑者；及供水管530，係限定自切換閥52〇朝外槽22〇 流動之水之路徑者。 供水部510與例如自來水之水龍頭（未圖示）連接。當切 換閥520開啟朝供水管53〇之水路時，水便供給到處理槽 200。 如第5圖所示，處理槽200具有：回收袋214，係攔截並 回收洗衣時自衣物分離之棉絨者；及流體平衡器215，係發 揮保持内槽210平衡之作用者。回收袋214及流體平衡器215 安裝在内槽210之上緣。 如第1圖所示，外槽220更具有：上板227,係與周壁221 之上緣224連接且橫跨在内槽21〇上者；及内蓋229，係安裝 成可相對上板227上下旋動者。使用者可將上部殼體丨3〇之 蓋體139下方之内蓋229旋動至上方，以將衣物投入内槽 21〇。或者，使用者可將衣物自内槽21〇取出。當使用者將 内蓋229旋動至下方時，上板227與内蓋229之間便形成密封 構造。因此，處理槽200内之水就幾乎或完全不會自上板227 之開口部漏出。 洗衣機100更包含有使用以使衣物乾燥之乾燥空氣循 %、之循環系統600。循環系統_具有：熱交換器⑽，係管 201239150 型且與連接導#226連接者；Μ”6ΐι，料水自切換 閥520朝熱交換器_導引者。當切換閥520開啟朝導引管 611之水路時，水便供給到熱交換器61〇。 熱交換器610具有：與連接導管226連接之下端部612; 及與導引管611連接之上端部613。朝上方流動之乾燥空 氣，與自熱交換器6H)之上端部613流入之水進行熱交換。 於是，乾燥空氣可適當除濕。 循環系統_更具有安裝在背面壁123之冷卻扇㈣。冷 卻扇620朝熱交換器61G送風，使乾燥空氣冷卻。於是，促 進乾燥空氣之除濕。 循環系統600具有：送風扇63〇，係將已除濕之乾燥空 氣送入處理槽2GG者；加熱器64Q ’係在送風扇㈣與處理槽 2〇〇之間將乾燥空氣加熱者；及導人管㈣1將已加熱之 乾燥空氣導引到處理槽200者。導入管65〇與上板227連接。 循環系統600可通過導入管650將乾燥空氣送入處理槽 200，並通過連接導管226將乾燥空氣回收。於是，達成處 理槽200周圍之乾燥空氣之循環。 洗衣機100更包含有連接殼體11〇與外槽220之懸掛單 元240。支持外槽220之懸掛單元240，可減弱自外槽220朝 殼體110傳送之振動。 第6圖係正面壁124與右壁126之間之角落部周圍之概 略放大平面圖。利用第1圖、第2圖、第4圖及第6圖來進一 步說明洗衣機100。 迴轉盤230、内槽210及外槽220，配設成略同心。在脫 11 201239150 水步驟時，含水之較重衣物會與内槽210之周壁211碰撞。 或者，衣物可能會偏布不均。衣物之碰撞及/或偏布不均， 將引起處理槽200之振動。 外槽220之周壁221具有：與内槽210之周壁211相對之 内面241 ;及位在與内面241相反側之外面242 ^外面242與 側壁部121相對。如第6圖所示，外面242近接於側壁部121。 洗衣機100更包含有加速度感測器700。安裝在周壁221 之外面242之加速度感測器700，檢測外面242之加速度，作 為關於脫水槽之振動之資訊。又，加速度感測器700將對應 外面242之加速度之檢測訊號輸出至控制裝置150。本實施 態樣中，加速度感測器700與第4圖相關說明之切換元件 152 ’均作為感測器單元之用。又，加速度感測器7〇〇例示 作為第2感測器元件。 加速度感測器700宜檢測外槽220之徑向之加速度分量 及外槽220之圓周方向之加速度分量之至少其中之一。因 此’遂可適切測定外槽220之振動《加速度感測器700更宜 在外槽220之徑向之加速度分量及外槽220之圓周方向之加 速度分量之外，也檢測上下方向（即，相對外槽220之徑向 及外槽220之圓周方向為正交之方向）之加速度分量。於 是’控制裝置150可依來自加速度感測器700之檢測訊號， 適切解析外槽220之振動模式。 加速度感測器700配設在由外槽220、正面壁124及右壁 126所包圍之角落部。由於形成在略圓筒狀外槽220與略矩 形筒狀側壁部121之間之空間，恰好適用於加速度感測器 12 201239150 700之配置，所以就無須確保有用於加速度感測器7〇〇配置 之追加空㈤。因此’本發明可提供小型的洗衣機1〇〇。 如第4圖相關說明’切換元件152配設在背面壁123與左 壁125之間之角落部。另_方面，加速度感測器7_己設在 正面壁124與右壁126之間。因此，加速度感測器7〇〇係配設 在相對切換元件152之殼體11〇之對角線上（即，在相對切換 元件152為第2方向SD)。 如第6圖所示’若處理槽2〇〇順時鐘方向旋轉，肇因於 在右壁126與背面壁123之間之衣物偏布不均及/或碰撞之 處理槽200的振動，便藉加速度感測器7〇〇檢測。肇因於在 左壁125與正面壁124之間之衣物偏布不均及/或碰撞之處 理槽200的振動，則藉切換元件152檢測。因此，處理槽2〇〇 旋轉半圈之期間以内，處理槽2〇〇之振動就藉加速度感測器 700及切換元件152之至少其中之一來檢測。於是，可迅速 檢測處理槽200之振動。 控制裝置150依自切換元件152及加速度感測器7〇〇輸 出之檢測訊號，解析處理槽2〇〇之振動模式。若處理槽200 之振幅超過針對振幅所定之閾值，控制裝置150便降低驅動 馬達410之轉速。或者’控制裝置15〇會令驅動馬達410停 止。因此’處理槽200之運動量降低，處理槽200之振幅變 /J、〇 如第6圖所示’外槽220之外面242近接於側壁部121。 如前所述，藉加速度感測器700及切換元件152，可迅速檢 測處理槽2〇〇之振動，所以外槽220之外面242與側壁部121 13 201239150 之間之空間即使狹窄’依然可避免或減少外槽220與側壁部 121之間碰撞。因此，本發明可提供小型的洗衣機1〇〇。 加速度感測器700宜安裝在外槽220之上緣224之附近 處。作業者欲調整或修綣加速度感測器700時，將上部殼體 130自下部殼體120分離後，就可輕易地觸及到安裝在外槽 220之上緣224附近處之加速度感測器700。因此，可輕易進 行加速度感測器700之維修、安裝或卸除。再者，由於外槽 220之上緣224之振幅較大，所以安裝在外槽220之上緣224 附近處之加速度感測器700可適切地檢測外槽220之加速 度0 第7圖係安裝在殼體110之熱交換器610之概略立體 圖。第8圖係右壁126與背面壁123之間之角落部之附近處之 概略放大平面圖。利用第1圖、第7圖及第8圖來說明熱交換 器610之安裝。 殼體110更具有安裝在背面壁123之背面蓋板129。熱交 換器610豎立設置在背面蓋板129與背面壁123之間。如第8 圖所示，熱交換器610配設在右壁126之附近處。因此，第1 圖相關說明之循環系統600，相對處理槽200之旋轉中心， 偏心配設在靠右壁126處。 循環系統600在右壁126附近，與處理槽200之上面（即 上板227)及下面（即外槽220之底壁222)連接。又，熱交換器 610沿背面壁123及背面蓋板129朝上方延伸。因此，循環系 統600以右壁126與背面壁123之間之角落部附近區域為中 心，抑制處理槽200之上下方向之位移。本實施態樣中，循 14 201239150 • 環系統600例示作為抑制單元。 另方面在右壁126與背面壁123之間之角落部之對 角線上’存在之左壁125與正面壁124之間之角落部附近區 域，處理槽200較易上下移動。例如，當使用者把水潑溢於 上板227上時’水將因此朝左壁丨25與正面壁124之間之角落 部流動。本實施態樣中，&於在左壁⑵與正面壁以之間 之角落部，未有加速度感測器7〇〇和切換元件152之感測器 單元存在，所以幾乎不會發生因潑溢於上板227上之水導致 加速度感測器700和切換元件152之感測器單元故障之情 形。因此，本發明可提供高可靠性的洗衣機丨〇〇。 依前述實施態樣業已說明相關之脫水裝置原理。前述 . 脫水裝置之結構，僅為例示。因此，在不脫離前述實施態 樣之原理之範圍内’亦可對脫水裝置進行各種變更。 前述實施態樣主要包含有以下結構。 前述實施態樣之一例之脫水裝置，包含有：脫水槽， 係方疋轉動作以將衣物脫水者；感測器單元，係輸出包括關

dewatering laundry. The detachment tank generally has a case where the inner tank is rotated to dehydrate the laundry, and the outer tank is used to receive the inner tank. A plurality of through holes are formed in the peripheral wall of the inner groove. The water removed from the dehydration of the clothes is discharged from the inner tank through the through holes. The outer tank receives water discharged from the inner tank. The laundry to be subjected to dehydration treatment is heavy due to water content. By the rotation of the inner groove, the laundry collides with the peripheral wall of the inner groove, thereby promoting the purpose of dehydration. On the other hand, the collision between the laundry and the peripheral wall of the inner tank causes vibration of the dewatering tank. The various dehydration devices of the present invention include a switching element that detects a large amplitude of the dewatering tank (for example, refer to Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. Hei. Japanese Laid-Open Patent Publication No. Hei No. 3-70595, Japanese Patent Laid-Open Publication No. Hei No. Hei No. Hei No. Hei No. Hei No. Hei. When the dewatering tank is largely displaced, the switching element is actuated and the inner groove stops rotating. In addition, the existing dehydration device uses an acceleration sensor instead of the switching element to detect the vibration of the dewatering tank (for example, see Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. The accelerating sensor can detect the dehydration and vibration of the high-speed rotation that is difficult to detect by switching the workpiece. The distribution of clothing in the dewatering tank varies randomly. Therefore, the aforementioned acceleration sensor and switching element cannot detect the vibration immediately due to the distribution of the clothes. SUMMARY OF THE INVENTION An object of the present invention is to provide a dewatering apparatus which can instantly detect the vibration of a dewatering tank. A dehydration device according to an embodiment of the present invention includes: a dewatering tank that rotates to dehydrate the laundry; and a sensor unit that outputs a detection signal including information on the vibration of the dewatering tank; and a control device, Controlling the dewatering tank according to the detection signal ', wherein the sensor unit has: a first sensor element that detects an amplitude of the first direction of the dewatering tank; and a second sensor element The first sensor element is disposed in a second direction opposite to the first direction. The dehydration device of the present invention can instantly detect the vibration of the dewatering tank.

When the processing tank 200 is largely displaced toward the corner between the rear wall 123 and the left wall Π 5, the rod portion 153 is rotated toward the rear wall 123 (and the upper rear wall 133) as shown in Fig. 4 . At this time, the signal generating portion 154 generates and outputs a detection signal for stopping (or decelerating) the rotation of the processing slot 200. In the following description, the direction ' toward the corner portion between the rear wall 123 and the left wall 125 is referred to as a first direction fd. Further, the direction opposite to the j-direction FD is referred to as the second direction SD. In the present embodiment, the knife 7 201239150 replacement element 15 2 is exemplified as the first sensor element. Fig. 5 is a schematic exploded perspective view of the processing tank 200. The treatment tank 200 will be described using Figs. 1 to 3 and Fig. 5. The treatment tank 200 has an inner tank 210 that rotates to dehydrate the laundry, and a groove 220 that accommodates the outer tank 210. The user can open the cover 139 of the upper housing 130 to receive the laundry into the inner tub 210. The inner groove 210 has a substantially cylindrical peripheral wall 211 and a bottom wall 212 that connects the lower end of the peripheral wall 211. The peripheral wall 211 is formed with a plurality of through holes 213. The water removed from the laundry dewatering is discharged from the inner tank 210 through the through hole 213. The outer tank 220 receives water discharged from the through hole 213. The outer groove 220 has a substantially cylindrical peripheral wall 221 and a bottom wall 222 that connects the peripheral wall 221 . The peripheral wall 221 has a lower edge 223 of the mounting bottom wall 222 and an upper edge 224 on the opposite side of the lower edge 223. In the present embodiment, the lower edge 223 is exemplified as the first edge, and the upper edge 224 is illustrated as the second edge. As shown in FIG. 1, the bottom wall 222 is formed with an opening 225. The water removed from the laundry dewatering is discharged from the outer tub 220 through the opening portion 225. The washing machine 100 further includes: a connecting duct 226 connected to the opening portion 225; and a drain system 300 for discharging water to the outside of the casing 110. As shown in Fig. 2, the base portion 122 has a back wall 143 which is slightly flush with the back wall 123 of the side wall portion 121, and a front wall 144 which is slightly flush with the front wall 124 of the side wall portion 121; The left wall 125 of 121 is slightly flush with the left wall 145; and the right wall 146 is slightly flush with the right wall 126 of the side wall portion 121. The lower back wall 143 is formed with a drain port 142. As shown in Fig. 1, the drainage system 300 has a drain pipe 31A having a first end portion 311 connecting the connection pipe 226 with 201239150, and a second end portion 312 connected to the drain port 142; and a drain valve 320' Under the control of the control device 15 , the drain pipe 310 is switched. When the drain valve 320 opens the drain pipe 31, the water in the outer tank 220 is discharged to the outside of the casing 110 through the drain pipe 310. As shown in Figs. 1 and 5, the processing tank 200 has a substantially disk-shaped rotary disk 230. The turntable 230 has a circular plate portion 231 that spans the bottom wall 212 of the inner groove 210, and a tilt ring 232 that protrudes upward from the peripheral edge of the circular plate portion 231. The tilt ring 232 extends upward. The turntable 230 further has a stirring rib 233 protruding from the upper surface of the circular plate portion 231 and the inclined ring 232. The agitating ribs 233 extend radially. The turntable 230 rotates during washing of the laundry and/or during drying of the laundry. Therefore, the laundry is appropriately stirred during the aforementioned steps. The washing machine 100 further includes a driving mechanism 400 for selectively rotating the inner tank 210 and the rotary disc 230 under the control of the control device 150. The driving mechanism 400 has a driving motor 410 for generating an inner groove 210 or a rotary disk. 230. The driving force of the rotation; the first shaft 420 is connected to the inner groove 210; the second shaft 430' is connected to the rotary disk 230; and the clutch device 440 transmits the driving force of the drive motor 410 to the first The switch between the shaft 420 and the second shaft 430 is switched. The drive motor 410 and the clutch device 440 that operate under the control of the control device 150 are fixed to the bottom wall 222 of the outer tub 220. The first shaft 420 penetrates the bottom wall 222 of the outer tank 220 and is connected to the bottom wall 212 of the inner tank 210. The second shaft 430', which is concentrically rotated with the first shaft 420, protrudes from the first shaft 420 and is connected to the rotary disk 23A of the inner groove 210. In the present embodiment, the drive motor 41 is exemplified as a drive source. When the washing step for washing the laundry is performed, the clutch device 440 switches the transmission path of the driving force to transmit the driving force to the second shaft 430. Thus, the rotary disk 230 rotates in the inner groove 210 when the 201239150 step is washed. As shown in Fig. 1, the washing machine 100 further includes a water supply system 500 for supplying water for washing laundry to the treatment tank 200. The water supply system 5A includes a water supply unit 510 that is attached to a water supply port 501 (see FIG. 3) formed on the top wall 131 of the upper casing 13A, and a switching valve 520 that is switched by the water supply unit 51. The water path; and the water supply pipe 530 is a path that defines water flowing from the switching valve 52 to the outer groove 22〇. The water supply unit 510 is connected to, for example, a tap (not shown) of tap water. When the switching valve 520 opens the water path toward the water supply pipe 53, the water is supplied to the treatment tank 200. As shown in Fig. 5, the treatment tank 200 has a recovery bag 214 which intercepts and recovers the lint separated from the laundry during washing, and a fluid balancer 215 which acts to maintain the balance of the inner tank 210. The recovery bag 214 and the fluid balancer 215 are mounted on the upper edge of the inner tank 210. As shown in FIG. 1 , the outer groove 220 further has an upper plate 227 connected to the upper edge 224 of the peripheral wall 221 and spanning the inner groove 21 ;; and an inner cover 229 mounted to be opposite to the upper plate 227 Rotate up and down. The user can rotate the inner cover 229 under the cover 139 of the upper casing 至3 to the upper portion to put the laundry into the inner groove 21〇. Alternatively, the user can take the laundry out of the inner tub 21. When the user rotates the inner cover 229 to the lower side, a seal structure is formed between the upper plate 227 and the inner cover 229. Therefore, the water in the treatment tank 200 leaks almost or completely from the opening of the upper plate 227. The washing machine 100 further includes a circulation system 600 that uses dry air to dry the laundry. Circulatory system_has: heat exchanger (10), system type 201239150 and is connected with connection guide #226; Μ"6ΐι, feed water from switching valve 520 towards heat exchanger_leader. When switching valve 520 opens to guide When the water path of the pipe 611 is passed, the water is supplied to the heat exchanger 61. The heat exchanger 610 has an end portion 612 connected to the connecting pipe 226, and an upper end portion 613 connected to the guiding pipe 611. Dry air flowing upward The heat exchange is performed with the water flowing in from the upper end portion 613 of the heat exchanger 6H. Thus, the dry air can be appropriately dehumidified. The circulation system _ further has a cooling fan (4) mounted on the back wall 123. The cooling fan 620 faces the heat exchanger 61G The air is blown to cool the dry air, thereby promoting the dehumidification of the dry air. The circulation system 600 has a blower 63 〇, which sends the dehumidified dry air to the treatment tank 2GG; the heater 64Q 'is connected to the blower (4) and the treatment The drying air is heated between the slots 2; and the guiding tube (4) 1 guides the heated drying air to the processing tank 200. The introduction tube 65 is connected to the upper plate 227. The circulation system 600 can be passed through the introduction tube 650 Dry air The treatment tank 200 is introduced into the treatment tank 200, and the dry air is recovered by the connection conduit 226. Thus, the circulation of the dry air around the treatment tank 200 is achieved. The washing machine 100 further includes a suspension unit 240 connecting the casing 11 and the outer tank 220. The suspension unit 240 of 220 can attenuate the vibration transmitted from the outer tank 220 toward the casing 110. Fig. 6 is a schematic enlarged plan view of the periphery of the corner portion between the front wall 124 and the right wall 126. Using Fig. 1 and Fig. 2 4, and 6 to further illustrate the washing machine 100. The turntable 230, the inner tank 210 and the outer tank 220 are arranged to be slightly concentric. When the water step 11 201239150 is taken, the heavier water containing clothes and the inner tank 210 The peripheral wall 211 collides. Alternatively, the laundry may be unevenly distributed. The collision of the laundry and/or unevenness of the cloth may cause vibration of the processing tank 200. The peripheral wall 221 of the outer groove 220 has a surface opposite to the peripheral wall 211 of the inner groove 210. The inner surface 241 is located on the outer surface 242 opposite to the inner surface 241. The outer surface 242 is opposite to the side wall portion 121. As shown in Fig. 6, the outer surface 242 is adjacent to the side wall portion 121. The washing machine 100 further includes an acceleration sensor 700. Installed outside the perimeter wall 221 The acceleration sensor 700 of the surface 242 detects the acceleration of the outer surface 242 as information about the vibration of the dewatering tank. Further, the acceleration sensor 700 outputs a detection signal corresponding to the acceleration of the outer surface 242 to the control device 150. This embodiment The acceleration sensor 700 and the switching element 152' described in connection with Fig. 4 are both used as the sensor unit. Further, the acceleration sensor 7 is exemplified as the second sensor element. The acceleration sensor 700 It is preferable to detect at least one of the radial acceleration component of the outer groove 220 and the acceleration component of the outer groove 220 in the circumferential direction. Therefore, the vibration of the outer groove 220 can be appropriately measured. The acceleration sensor 700 is preferably disposed in the radial direction of the outer groove 220 and the acceleration component in the circumferential direction of the outer groove 220, and also detects the up and down direction (ie, relatively outward). The acceleration component of the radial direction of the groove 220 and the circumferential direction of the outer groove 220 is an orthogonal direction. Then, the control device 150 can appropriately analyze the vibration mode of the outer slot 220 according to the detection signal from the acceleration sensor 700. The acceleration sensor 700 is disposed at a corner portion surrounded by the outer groove 220, the front wall 124, and the right wall 126. Since the space formed between the slightly cylindrical outer groove 220 and the slightly rectangular cylindrical side wall portion 121 is just suitable for the configuration of the acceleration sensor 12 201239150 700, there is no need to ensure that the acceleration sensor 7 is configured. Additional space (five). Therefore, the present invention can provide a small washing machine. As described in Fig. 4, the switching element 152 is disposed at a corner between the rear wall 123 and the left wall 125. On the other hand, the acceleration sensor 7_ is already disposed between the front wall 124 and the right wall 126. Therefore, the acceleration sensor 7 is disposed on the diagonal line of the housing 11〇 relative to the switching element 152 (i.e., in the second direction SD with respect to the switching element 152). As shown in Fig. 6, if the processing tank 2 is rotated in the clockwise direction, it is caused by the unevenness of the laundry between the right wall 126 and the back wall 123 and/or the vibration of the processing tank 200 that collides with it. The acceleration sensor 7 detects. The vibration is detected by the switching element 152 due to the unevenness of the laundry between the left wall 125 and the front wall 124 and/or the vibration of the collision cell 200. Therefore, the vibration of the processing tank 2 is detected by at least one of the acceleration sensor 700 and the switching element 152 within a period in which the processing tank 2 is rotated by half a turn. Thus, the vibration of the treatment tank 200 can be quickly detected. The control device 150 analyzes the vibration mode of the processing tank 2 based on the detection signals output from the switching element 152 and the acceleration sensor 7. If the amplitude of the processing tank 200 exceeds the threshold determined for the amplitude, the control unit 150 lowers the rotational speed of the drive motor 410. Alternatively, the control device 15 will cause the drive motor 410 to stop. Therefore, the amount of movement of the treatment tank 200 is lowered, and the amplitude of the treatment tank 200 is changed to J, and as shown in Fig. 6, the outer surface 242 of the outer tank 220 is adjacent to the side wall portion 121. As described above, the acceleration sensor 700 and the switching element 152 can quickly detect the vibration of the processing tank 2, so that even if the space between the outer surface 220 of the outer groove 220 and the side wall portion 121 13 201239150 is narrow, it can be avoided. Or the collision between the outer groove 220 and the side wall portion 121 is reduced. Therefore, the present invention can provide a small washing machine. The acceleration sensor 700 is preferably mounted adjacent the upper edge 224 of the outer slot 220. When the operator wants to adjust or repair the acceleration sensor 700, the upper housing 130 is separated from the lower housing 120, and the acceleration sensor 700 installed near the upper edge 224 of the outer groove 220 can be easily accessed. Therefore, the repair, installation or removal of the acceleration sensor 700 can be easily performed. Moreover, since the amplitude of the upper edge 224 of the outer groove 220 is large, the acceleration sensor 700 installed near the upper edge 224 of the outer groove 220 can appropriately detect the acceleration of the outer groove 220.
