L· ittr J 發明背景 到目前為止，滾筒式乾衣機和洗衣乾衣機，是讓用於 使衣服乾無的乾無空氣通過風路而供給到滚筒内。乾燥空 氣接觸被投入滾筒的衣服，從衣服攫取水份。此結果，衣 服被適當地乾燥。 如上所述，接觸過衣服的乾燥空氣，因為從衣服攫取 水份而呈高濕。高濕度的乾燥空氣被排出到滾筒外的風 路。特別是，因為要在狹小的滾筒空間内對衣服施行乾燥 程序，所以各種用於使衣服在短時間均勻有效率地乾燥之 方法已經被考慮到（例如，特開2008-259549號公報）。 第16圖所示為特開2008_259549號公報中記載之習知 的滾筒式洗衣乾衣機的主要部分的概略圖。如第16圖所 示，省知之滾筒式洗衣乾衣機具備切換閥1〇2。切換閥1〇2 用來切換被送風機1〇1吸進去之乾燥空氣的送風路徑。該習 知之滾筒式洗衣乾衣機是在乾燥程序中控制切換閥，在 恒速乾燥過料，將乾燥空氣從㈣開㈣附近的前側吹 出口人到滾请内。另外，在減速乾燥過程時，洗衣乾衣機 將乾燥工從όχ在滾《後部的後側吹出口吹到滾筒内。此 201215732 結果，衣服在短時間内均勻地乾燥。 上述的滾筒式洗衣乾衣機具備採用關閉風路的部件 (例如’閥）形成㈣換機構。城機構會適當㈣換乾燥空 氣的送風路徑。例如，切換機構在用閥賴—個送風路徑 的同時，會打開另—個送風路徑。此結果，可以選擇所要 的送風路徑。 …、而上述的切_構有涉及安定地切換送風路徑的 控制之課題。例如，切換機構的閥如果夾有異物，閥會被 卡住，閥的位置就不能被適當地控制。 對送風路徑的切換控制如果實施得不恰當，也有不能 選擇所需要的送風路徑的情形。或者，也有發生空氣從送 風路㈣漏的情形。此結果，乾燥性能大幅度地降低。從 而，乾燥時間變長，消費電力也増大。此外，也有在衣服 上發生乾燥斑或皺褶的情形。 使洗滌後 谷·易出現因 特別是，纖維屬或其他的異物會大量存在於 的衣服乾燥之乾衣機或洗衣乾衣機中。因此 上述異物以致卡住和空氣洩漏的情形。 C 明内容]| 發明概要 以發生因異物導致卡住 以及具備切換機構之 本發明的目的在於提供—種難 或空氣洩漏之信賴度高的切換機構， 乾衣機及洗衣乾衣機。 在本發明的—财面，轉機構具備 通過之第1送風路徑和，從該仏、^ 人运的抓體 ^第送風路徑分歧，前述流體 201215732

用以實施發明之最佳形態 以下，將用所附圖式說明一實施態樣之滾筒式洗衣乾 衣機。再者’圖式和以下說明中的詳細構造僅為一例，並 非限定切換機構、乾衣機及洗衣乾衣機的原理之例。 (洗衣乾衣機的構造） 第1圖係根據一實施態樣之滾筒式洗衣乾衣機的側面 斷面圖。以下說明的洗衣乾衣機也是乾衣機的例示。 第1圖所示的洗衣乾衣機500具備收容洗務物之筒狀的 ⑧ 6 201215732 滾筒1。滾筒]在前方開口。另外，滾筒丨具有和開口部相對 之底面。本實施態樣中，滾筒丨是收容部的例示。 洗衣乾衣機500進—步具備貯存洗條水之筒狀的水槽 2。滾筒1被支撐在水槽2内。洗衣乾衣機5〇〇進一步具備安 裝在水槽2的背面之驅動馬達3。驅動馬達3使滾筒1旋轉。 滾请1的紅轉轴朝向前方往上方傾斜。 洗衣乾衣機500進一步具備由使用者來開閉的門35。門 35對滾筒1的開口部形成對向。使用者打開門35，可以將洗 滌物（衣服)取出放入滾筒1。 洗衣乾衣機500進—步具備安裝在水槽2的給水管（未 圖不出）和，安裝在給水管的給水閥（未圖示出）。給水閥開 啟時，水通過給水管供給到水槽2。洗衣乾衣機5〇〇進一步 具備連接到水槽2的排纟管4〇和，安裝在排水管4〇的排水閥 41。排水閥41開啟時，水從水槽2排出。 洗衣乾衣機500進-步具備使乾燥衣服用之乾燥空氣 循環的送風部4。岐科4钟㈣W之乾Μ氣從洗務 物攫取水分而呈高滅態。本實施態樣中乾燥空氣是流體 的例不。 排出口 5形成於水槽2。乾燥空氣之後通過位在滾筒i的 周面的周圍之排出口5，排到水槽2外部。 洗衣乾衣機500還具備將乾燥空氣除濕之除濕部6和， 加熱乾燥空氣之加熱部7。通過排出口 5之乾燥 入除 濕部6受到除濕。經過除濕部6除濕後之乾燥空氣:由^熱部7 201215732 洗衣乾衣機500進一步具備導引乾燥空氣之第1風路9 以及從第1風路9分歧的第2風路11。經過加熱的乾燥空氣被 導引到第1風路9或第2風路11中的一個。之後，乾燥空氣再 度流入滾筒1内。本實施態樣中，第1風路9是第1送風路徑 的例示。而，第2風路11是第2送風路徑的例示。 第1風路9包含在滾筒1的後方開口之第1吹出口8 ^第2 風路Π包含連通滾筒1的開口部之第2吹出口 1〇。第1風路9 的第1吹出口 8具有大於第2吹出口 10的斷面積。因此，對於 沿著第1風路9流動的乾燥空氣，其壓力損失小於沿著第2風 路11流動的乾燥空氣的壓力損失。因此，有更多量的乾燥 空氣從第1吹出口 8流入滚筒1内。因為第2吹出口 1〇比第1吹 出口 8的斷面積小，所以從第2吹出口 1〇吹出的乾燥空氣， 比從第1吹出口 8吹出的乾燥空氣更高壓且高速地流入滾筒 1内。 在洗衣乾衣機500的前側部分，滾筒1和水槽2之間的間 隙宜設計得儘可能小。這樣衣服就難以進入滾筒1和水槽2 之間的間隙。如同上述第1吹出口 8般的較大吹出口（壓力損 失小的吹出口）不易設於滾筒1和水槽2之間的狹小間隙。然 而，因為第2吹出口 1〇具有小於第丨吹出口 8的斷面積，所以 滾筒1和水槽2之間的狹小間隙，在高壓且高速的乾燥空氣 被吹出之第2吹出口 10的設置上可以適當地做應用。 在洗衣乾衣機500的後側部分，具有較大開口面積的第 1吹出口 8形成於較寬的水槽2的底面。洗衣乾衣機5〇〇還具 備覆蓋第1吹出口 8之蓋體36 ^體36上形成多個容許乾燥 201215732 空氣流動的小孔。因此，蓋體36整體具有大開口率。蓋體 36阻止衣服進入第1吹出口8。形成於水槽2底面之第1吹出 口8 ’達成壓力損失較少的乾燥空氣的流入。 本實施態樣中，滚筒1的旋轉軸朝向前方往上方傾斜。 滚琦1轉動的期間，襪子、手絹、短内襌之類的小衣物容易 偏到滾筒1的底面。另一方面，長袖内衣，長内褲，長柚襯 衫或長袖睡衣之類的長衣類容易偏向滚筒1的前方。 使用者如果將小衣物及長衣類混在一起投入滾筒丨，從 滾筒1的底部附近的第1吹出口 8吹出之大風量的乾燥空氣 就會先接觸不岣勻地分布在滾筒1的底部的小衣物。之後， 乾燥空氣閃過小衣物接觸不均勻地分布在滾筒1前部分的 長衣類°因此，小衣物及長衣類一同有效地被乾燥。如上 所述地被乾燥之小衣物上所產生的皺褶較少。 長衣類因為乾燥中的攪動而容易扭在—起，所以和小 衣物相比，長衣類上容易發生皺褶。如上所述，長衣類因 為容易不均勻地分布在滚筒1的前側區域，所以從第2吹出 口 10吹出的乾燥空氣，比從第1吹出口8吹出的乾燥空氣， 更可以快速地乾燥長衣類。此外，如上所述，因為從第2吹 出口 10吹出之乾燥空氣是高壓且高速的，所以從第2吹出口 10吹出的乾燥空氣會適當地將長衣類展開，並且，可以使 其在滾筒1内大幅度地移動。此結果，從第2吹出口 1〇吹出 的乾燥空氣可以減少發生在長衣類上的皺褶。 第1風路9和第2風路11的分歧部形成於送風部4的下 游。洗衣乾衣機500進一步具備配設在第1風路9和第2風路 201215732 11的分歧部之風路切換部12。風路切換部12將乾燥空氣的 通過路彳_換到第1風路9及第2風路11巾的-個。此結果， 從送風部4送來的乾燥空氣通過第1風路9及第2風路n當中 的一個’供給到滾筒卜本實施態樣中，風路切換部12是切 換機構的例示。 風路切換部12具備可轉動地樞接於第1風路9和第2風 路U的刀歧部之遮板21和，旋轉驅動遮板21的驅動部。遮 板21直立地轉動’當關閉第2風路11 (第1圖中，以符號「a」 表示之遮板21)時，第1風路9被打開。因此，送風部4送出 的乾燥空氣通過第1風路9。當遮板21相對於從送風部4送出 之乾燥空氣的流動傾斜成橫斷狀態，將第1風路9關閉時(第 1圖中’以符號「b」所示之遮板21)，第2風路11被打開。 因此’送風部4送出的乾燥空氣通過第2風路11。風路切換 部12敘述於後。 洗衣乾衣機500還具備規定乾燥空氣的循環路徑之循 環風路13。送風部4、風路切換部12、除濕部6及加熱部7配 設在循環風路13中。循環風路13的一端部連接水槽2,並形 成排出口5 °滾筒1内的乾燥空氣從排出口5被排出之後，通 過除濕部6及加熱部7。送風部4將通過加熱部7的乾燥空氣 再度送到滾筒1。風路切換部12決定送風部4之後的乾燥空 氣的路徑。風路切換部12如果容許乾燥空氣往第1風路9流 動，乾燥空氣就會通過第丨吹出口 8流入滾筒丨内。風路切換 部12如果容許乾燥空氣往第2風路u流動乾燥空氣就會通 過第2吹出口 10流入滾筒1内。因此，乾燥空氣會在洗衣乾 201215732 衣機500内循環。 配設在加熱部7和風路切換部12之_送 過加熱部7加熱的乾燥空氣沿循環風路13送到下;。1將f 4具備風機4a和，使風機知旋轉的風機馬料。風路== 12如果將1齡氣的路徑切換到第戦9,送風部4的風機 會讓卿a_，使得通萄丨風路9之乾燥空氣的 、-里達到被設定成比通過第2風路u的乾燥空氣的流量多 之預定風量。風路_部12如果將乾燥线的路徑切換到 第2風路U，送風部4的風機馬達财讓風機4a旋轉，使得 通過第2風路11之乾燥空氣㈣速達到被設定纽通過第1 風路9的乾燥空氣的流速快之預定風速。例如，通過第卜欠 出口 8之乾燥空氣的流速如果是約1() m/s，則通過第2吹出口 10之乾燥空軋的流速設定在約5〇 m/s以上亦可。再者只要 在第2吹出口 1〇之乾燥空氣的流速，比在第丨吹出口 8之乾燥 二氣的流速高，則通過第i吹出口 8及第2吹出口 1〇之乾燥空 氣的流速也可以設定成其他數值。 依據本貫施態樣之滾筒式洗衣乾衣機5〇〇係使通過第j 風路9之乾燥空氣的流量大於通過第2風路1〇之乾燥空氣的 机里。另外’洗衣乾衣機5〇〇是讓通過第2風路丨丨的第2吹出 1 〇之乾燥空氣的流速高於通過第1吹出口 8之乾燥空氣的 机速。另外’洗衣乾衣機5〇〇在乾燥程序的過程中，使風路 切換部12動作，在第1風路9和第2風路u之間切換乾燥空氣 的楯環路徑。 排出口 5形成於比從第2吹出口 10，更從第1吹出口 8疏 201215732 遠的位置（亦即，排出口5形成於比第1吹出口 8更靠近第2吹 出口 10的附近）。因此，排出口5形成於滾筒1的前部，而不 是滾筒1的後部。排出口 5也可以形成於配設在滾筒1的前方 之第2吹出口 1〇的附近。此結果’排出口5和第1吹出口 8的 距離變得比較長。 排出口 5形成於滾筒1的上方。這樣，接觸過衣物之乾 燥空氣會被有效地排出到上方。再者，本實施態樣的原理 如果被應用到不具有洗滌功能之滾筒式乾衣機，則用於從 滾筒1排出乾燥空氣之排出口，也可以不形成於滚筒的上 方。本實施態樣中’洗衣乾衣機500用洗滌水進行衣物的洗 滌。因此，為了讓洗滌水往排出口 5流入的情形不易發生， 排出口5被形成於比洗滌水的水位更上方。 設置於滚筒1的前方之第2吹出口 10,在滾筒1的上部區 域開口。因此，隨著滾筒1的轉動，高壓且高速的乾燥空氣 有效地對著浮到上方的衣服吹。這樣，從第2吹出口 10吹出 之乾燥空氣就可以有效地減少衣服上產生的皺褶。 洗衣乾衣機5〇〇還具備配設在水槽2的下方之減震器 14。減震器14支撐水槽2。在例如’衣服脫水期間，衣服不 均勻地分布在滚筒1内’使得滾筒1的重量分佈失衡。滾筒1 之重量分佈的失衡’在滚淹1旋轉時引起水槽2的振動。減 震器14使水槽2的振動適當地衰減° 減震器14具備對應水槽2内衣服的重量而上下活動的 軸141。洗衣乾衣機500進一步具備以軸141的變位量為基 礎，檢測水槽2内的衣服的量之檢測部15。檢測部15安裝在 ⑤ 12 201215732 減震器14上。 本實施態樣之滾筒式洗衣乾衣機500為熱泵式，對乾燥 空氣進行除濕及加熱。洗衣乾衣機500具備熱泵裝置50。熱 泉裝置50備有，壓縮冷媒之壓縮機16和，使受壓縮而變成 高溫且高壓之冷媒的熱放熱之放熱器17和，降低高壓冷媒 的壓力之降壓節流部18和’利用經由降壓節流部丨8降成低 壓之冷媒攫取周圍的熱之吸熱器19和，連結到壓縮機16、 放熱器17、降壓節流部18及吸熱器19之管路20。冷媒沿管 路20循環。吸熱器19作為上述除濕部6使用。另外，放熱器 17作為上述加熱部7使用。 本實施態樣中，滾筒式洗衣乾衣機5〇〇採用熱泵裝置5〇 進行衣服的乾燥。本實施態樣的原理亦可替代性地應用於 具備用以乾燥衣服之其他構造的裝置。例如，乾燥空氣亦 玎採用對乾燥空氣直接喷水之水冷裝置來除濕。另外，亦 玎採用加熱器加熱乾燥空氣。 第2圖係滾筒式洗衣乾衣機5〇〇的概略方塊圖。洗衣乾 衣機500將利用第1圖及第2圖做說明。 洗衣乾衣機500具備控制部7〇和輸入設定部32。使用者 在輸入設定部32輸入關於洗衣乾衣機5〇〇的動作的設定資 訊。控制部7G-邊監測根據設定資訊做動作之洗衣乾衣機 500的各種條件’-邊以設定資訊為基礎，對絲、漂洗、 脫水及乾燥這一連串的運轉動作加以控制。例如，在乾燥 程序中’控制部70用馬達驅動電㈣控制驅動馬達3的旋轉 數。另外’控㈣7G控制送風部4及綠|置5⑽動作，對 13 201215732 乾燥空氣的流量、溫度和濕度等的各種參數進行調整。此 外，控制部70控制風路切換部12，在第丄風路9和第2風路11 之間選擇性地切換乾驗氣的流祕徑。控制部％亦可包 含’例如，CPU (Central Processing Unit)(未圖示出），儲存 程式之ROM (Read 〇nly M_ry)，於實行各種處理時储^ 程式或數狀RAM (Rand()m Ae⑽Me_y)輸人輪出介 面’以及連接其等之匯流排。 控制部70具備定時器71。定時器71設定第丨設定時間及 第2設定時間。再者，第1設定時間及第2設定時間於後敘 述。定時H71也可以是，例如’作為控㈣％執行動作之 内部功旎的一部分而包含在内之内部定時器。或者定時 器也可以是做成和控制部不同形式之定時裝置。 本實施態樣之洗衣乾衣機500具備單一的第丨吹出口 8。或者，洗衣乾衣機亦可具備複數個第丨吹出口。 同樣地，洗衣乾衣機5〇〇具備單一的第2吹出口 1〇。或 者，洗衣乾衣機亦可具備複數個第2吹出口。 第3圖及第4圖為風路切換部12的概略斜視圖。第5圖是 遮板21的概略圖。風路切換部12採用第丨圖至第5圖做說明。 如上所述，風路切換部12被安裝於第1風路9和第2風路 11之間的分歧部。本實施態樣中，如第、第3圖及第4圖 所示，第1風路9從送風部4起直線地延伸。第2風路u從第} 風路9分歧。本實施態樣中，第2風路n對第丨風路9以幾近 直角（幾近90度）的角度分歧。或者，第2風路對第丨風路的分 歧角度也可以是其他數值。 14 201215732 如上所述，因為用於導引流量比較大的乾燥空氣之第工 風路9從送風部4起直線地延伸，所以沿第丨風路$流動之乾 燥空氣的壓力損失較小1此，流量大的乾燥空氣從第浪 路9起被有效地送往滚筒1内。 如第3圖及第4圖所示，用於引導流量比較大的乾燥空 氣之第1風路9’具有比用於引導以高速流動的乾燥空氣之 第2風路U來得大的斷面積（容許乾燥空氣流動之斷面區域 的面積）。 本實施態樣中，如第3圖及第4圖所示，在第i風路9和 第2風路U的分歧部周圍，第1風路9的斷面形狀並不是圓 形，而是近於矩形。因為分歧部周圍之^風路9的斷面形 狀近於矩雜，所以第1風路9的料是平坦的。因此，其 他零件容易被安裝於第丨風路9之平坦的周壁。 本實施態樣中，在第1風路9和第2風路u的分歧部周圍 之細物斷面形狀近於_。或者，在第丨風路9和第2 風路11的分歧部周圍之第1風路9的斷面亦可為其他形狀。 例如在第1風路9和細路u的分歧部周圍之第1風路9的 斷面亦可形成為近於圓形。 第6圖及第7圖是將乾燥空氣從送風部4導引到以風路 和第風路_的分歧部為止之導引風路的概略平面圖。 導引風路用第1圖、第3圖至第7圖做說明。 洗衣乾衣機_進-步具備將乾燥空氣從送風部4導引 到第1風路Μ聰丨職蝴為止彻風路⑷導 引風路24具㈣怖5，㈣缝料物的風機4_ 15 201215732 收容空間。收容部件25包含示於第6圖之第1收容壁25a和示 於第7圖之第2收容壁25b。第1收容壁25a及第2收容壁2513分 別包含向外方突出之接合部25c^第1收容壁25a重疊到第2 收容壁25b’再用螺栓之類的合適的接合部件，將接合部25c 接合。送風部4的風機4a被收容於由重疊的第1收容壁253和 第2收容壁25b所形成之内部空間。 在收容部件25的下游配設著作為第1風路9的一部分使 用之第1導引風路26。上述分歧部形成於第1導引風路％的 正刖方。如第6圖所示，導引風路24進一步具備與第i收容 壁25a—體形成的風路片26a和，與第2收容壁25b 一體形成 的風路片26b。風路片26a重疊到風路片26b上，形成從收容 部25到第1導引風路26正前方的分歧部為止的區間。 本實施態樣中，如第6圖所示，第丨收容壁25a及風路片 26a係用合成樹脂之類的材料—體成型。另外，如第7圖所 示，第2收容壁2513及風路片26b也是用合成樹脂之類的材料 一體成型。風路片26a、26b和第1收容壁25a及第2收容壁25b 相同刀別具備接合部25c。風路片26a重疊到風路片26b , 再用螺栓之類的合適的接合部件將接合部…接合，就會形 成從收容部件25到第1導引風路26正前㈣分歧部為止的 區間。再者’示於第3圖之分歧部的上側部分，相當於第6 圖所說明的風路片26a。另外’示於第3圖之分歧部的下側 部分，相當於第7圖所說明的風路片26b。 如第6圖及第7圖所示，導引風路％具備分別從風路片 26a、26b的内面突出之凸肋28。當風路片26a 、26b重#時， 201215732 升乂成於風路片26a之凸肋28及形成於風路片26b之凸肋28， 形成大致C型的突出輪廓。 第1風路9從第1導引風路26更往下游延伸直到形成於 水槽2之第1吹出口 8為止。如第6圖所示，風路片26a上形成 有作為第2風路11的一部分使用之第2導引風路27。 如第3圖所示，設於第1風路9和第2風路11之間的分歧 之風路切換部12具備遮板21和，減速齒輪22和，驅動遮 板21之驅動馬達23和，凸肋28。 遮板21選擇性地遮蔽第1風路9及第2風路11中的一 個。第3圖中示出遮蔽第2風路11之遮板21。此結果，乾燥 空氣會通過第1風路9做循環。第4圖示出遮蔽第丨風路9之遮 板21。此結果’乾燥空氣會通過第2風路丨1做循環。 如第5圖所示，遮板21具備安裝在第1風路9和第2風路 11之間的分歧部之轉動軸部21a和，設於轉動軸部21a的上 端之齒輪安裝部21b和，固定在轉動軸部21a上之遮蔽部 21c。遮蔽部21c選擇性地遮蔽第1風路9及第2風路11中的一 個。本實施態樣中，遮蔽部21c是遮蔽部件的例示。 遮板21係採用，例如，合成樹脂之類的材料形成。遮 板21的遮蔽部21c包含上緣21x、下緣2iy及前端緣21z。上 緣21x、下緣21y及前端緣21z的尺寸及輪廓係依導引風路24 的分歧部中之斷面形狀而定。 遮板21的遮蔽部21 c具有比連接到分歧部之第2風路11 的斷面積大的面積。如第3圖所示，配設在對第2風路11形 成直交的位置之遮蔽部21c，完全遮蔽第2風路η。 17 201215732 遮板21的遮蔽部2ic比第丨風路9的斷面形成得稍小，以 便在形成於導引風路24之分歧部内轉動。遮蔽部2lc的上緣 21x及下緣2ly與，第丨風路9的内面之間形成有間隙。上緣 21x及下緣21y與，第丨風路9的内面之間設計過度狹小的間 隙不僅對女裝精度的要求將會過高，而且容易導致異物 夾入该間隙，因此，遮蔽部21c的上緣21x及下緣21y與，第 1風路9的内面之間，間隙也可以設定在大約丨5 。 如第3圖、第6圖及第7圖所示’在第丨風路9的内面形成 有凸肋28。凸肋28與遮板21的遮蔽部21c的端緣(上緣21χ、 下緣21丫及前端緣21ζ)抵接。凸肋28在乾燥空氣的流動方向 中，比遮板21的遮蔽部21c形成在較下游。如第4圖所示， 當遮板21轉動遮蔽第丨風路9時，遮蔽部2U的端緣（上緣 21x、下緣21y及前端緣21z)抵接凸肋28。此結果，第丨風路 9被遮蔽部21 c與凸肋28完全地密封。 第8圖概略地顯示遮板21和凸肋28的抵接。再者，第8 圖概略地表示沿示於第4圖之A-A線的斷面。遮板21和凸肋 28的抵接將用第4圖及第8圖做說明。 凸肋28的突出量過大（從第i風路9的内面起的突出 量）’其結局是空氣阻力大。因此，凸肋28的突出量宜設定 成，例如，約2 mm。遮板21的遮蔽部21c之端緣(上緣2lx、 下緣21y及前端緣21z)與第1風路9的内面之間的間隙如果 設定成約1.5 mm，則突出量約2 mm的凸肋“與遮蔽部2lc 的重疊量約為〇·5 mm。約0.5 mm之重疊量對於密封第1風路 9是足夠的尺寸。再者，上述凸肋28的突出量、遮板21與第 18 ⑧ 201215732 9的内面之間的間隙，以及重疊量的數值是—個例 子，也可以針對這些尺寸參數設定其他數值。 第4圖中所示的角度Θ意指，從對第2風路11的遮蔽位置 到對第1風路9的遮蔽位置為止之遮板21的轉動角度（或 者相對於第1風路9的延伸方向，抵接於凸肋28之遮板21 Μ蔽部21e形成的角度^本實施態樣中，角度㊀設定成約 50度。角度Θ如果設定成小於9〇度的角度（本實施態樣中， 約50度），起因於流往從第丨風路9分歧之第2風路u的乾燥 空氣與遮板21的遮蔽部21c的衝突所造成之壓力損失，就會 變知比較小（與角度Θ設定成90度時相比”從而，形成往第2 風路11緩緩彎曲的乾燥空氣的流路。如此，乾燥空氣即有 效率地流入第2風路11。 本實施態樣中，角度Θ被設定成大於45度的角度（本實 施態樣中，約50度）。因為角度θ被設定成大於45度的值， 所以彎向第2風路11之乾燥空氣的流路的斷面積，變得比角 度Θ被設定成45度時大。本實施態樣中，考慮到在形成於第ι 風路9和第2風路11之間的分歧部的轉角部之壓力損失及^ 燥空氣的流路的斷面積，角度Θ宜設定在5〇度到55度的範圍 配設在遮蔽第1風路9的遮板21下游的凸肋28，與遮板 21的遮蔽部21c呈大致平4亍。遮板21的遮蔽部2ic的巧緣（ 緣21χ、下緣21y及前端緣21z)，在對第1風路9的遮蔽位 與凸肋28無間隙的抵接。在遮板21的遮蔽部2lc與凸肋u的 抵接區域，宜設置〇形環之類的密封部件。密封部件會降 從遮板21的遮蔽部21c與凸肋28之間的空氣洩漏^ 〇二環= 201215732 類的密封部件亦可安裝在遮板21的遮蔽部21c及凸肋28中 的一者上。 第9圖係導引風路24的概略斜視圖。用第3圖至第6圖及 第9圖說明遮板21的安裝。 配設於第1風路9的内部之遮板21的轉動軸部21a的一 端部，可轉動地樞接於導引風路24。轉動轴部2la的另一端 側，貫通導引風路24上所穿設的安裝孔24a (參照第6圖及第 9圖），可轉動地樞接著。在貫通安裝孔24a，往第丨風路9的 外部突出之轉動軸部21a的端部上設有齒輪安裝部21b (參 照第5圖）。如第3圖及第4圖所示，減速齒輪22之第2齒輪22b 被安裝在齒輪安裝部21b上。 將驅動馬達23的驅動力往遮蔽部21c傳達之減速齒輪 22具備第1齒輪22a (圓筒形的正齒輪)和，與第1齒輪22a>j齒 合之第2齒輪22b (分割成扇形之正齒輪）。第1齒輪22a比第2 齒輪22b的直徑小。第1齒輪22a作為小齒輪（小經齒輪）使 用。第1齒輪22a安裝在驅動馬達23的馬達旋轉軸23a上。驅 動馬達23的旋轉動力直接被傳達到第1齒輪22a。再者，從 驅動馬達23往第1齒輪22a之動力傳達，也可以不像上述的 直接傳達方式，而採用其他的動力傳達機構來達成。 與第1齒輪22a嚙合之第2齒輪22b隨著第1齒輪22a的旋 轉而轉動。因此，第1齒輪22a是作為驅動齒輪使用，第2齒 輪22b則作為被動齒輪使用。 以下的說明中，對第1齒輪22a (驅動齒輪）的齒數給予 「Z1」的記號。而，對第2齒輪22b (被動齒輪)的齒數給予 ⑧ 20 201215732 「Z2」的記號。減速齒輪22的減速比表示為Z2/Z1。 以下的說明中，對第1齒輪22a (驅動齒輪）的旋轉數給 予「N1」的記號。而，對第2齒輪22b (被動齒輪）的旋轉數 給予「N2」的記號。減速齒輪22的減速比表示為N1/N2。 安裝在第2齒輪22b之遮板21的驅動扭矩係對應減速齒輪22 的減速比而受到調整。 如上所述，利用驅動馬達23與減速齒輪22的組合，可 以獲得遮板21之足夠大的驅動扭矩。遮板21的驅動扭矩宜 設定成’例如，不會發生因遮板21與第1風路9之間夾到異 物而導致遮板21卡住。 第10圖為第1風路9與第2風路11的分歧部周圍之概略擴 大斜視圖。遮板21的驅動用第2圖至第4圖及第10圖做說明。 如第10圖所示，第1齒輪22a及第2齒輪22b以齒輪罩配 件29罩住。齒輪罩配件29抑制異物混入第丨齒輪22&與第2齒 輪22b的嚙合部，並且抑制外來異物混入第丨風路9内。 本實施態樣中，驅動馬達23係採用可雙向旋轉之步進 馬達。第2圖中說明的控制部7〇對驅動馬達23施加驅動脈 衝，調整驅動馬達23的旋轉量（旋轉角）。此結果，遮板21 的動作適當地獲得控制。 如第3圖所示，當遮板21受到驅動迎向第2風路丨丨的遮 蔽位置時，控制部70會對驅動馬達23施加超量的脈衝數以 便產生若干越程。這樣，當遮板21抵接到第2風路U周圍的 』面時’會在遮板21上施加定額的壓力。從而，遮板21可 以適當地遮蔽第2風路丨丨。 21 201215732 如第3圖所示，在導引風路24的外面形成有限制凸肋 3〇。限制凸肋30抵接扇形的第2齒輪22b之右端部22c，限制 第2齒輪22b之逆時針方向的轉動。因此，遮板21幾乎不產 生過度的逆時針方向的轉動。 同樣地，如第4圖所示，當遮板21受驅動迎向第丨風路9 的遮蔽位置時，控制部70會對驅動馬達23施加超量的脈衝 數以便產生若干越程。這樣，當遮板21抵接到凸肋28時， 會在遮板21上施加定額的壓力。從而，遮板21可以適當地 遮蔽第1風路9。 如第4圖所示，在導引風路24外面形成有限制凸肋31。 限制凸肋31抵接扇形的第2齒輪22b的左端部22d，限制第2 齒輪22b之順時針方向的轉動。因此，遮板21幾乎不產生過 度的順時針方向的轉動。限制凸肋3〇、31係通過將第丨風路 9和第2風路11的分歧部的轉角上部設成凹陷狀而形成。 (洗衣乾衣機的動作） 以下將說明上述滾筒式洗衣乾衣機5〇〇的動作及有利 的效果。 上述之洗衣乾衣機500減少了乾燥程序期間產生的衣 服皺褶。 在狹小的滾筒内，衣服以未完全伸展開的狀態被乾 燥。因此，通常在狹小滾筒内被乾燥的衣服上會產生許多 皺褶。這件事給使用者帶來不滿。特別是含棉多的衣服會 產生許多皺褶。因此，若棉的量增加，乾燥後的最終結果 容易變糟。 22 201215732 水分存在棉纖維内的期間，棉纖維彼此可以比較自由 地移動。因此，隨著滾筒的旋轉而受到攪動的衣服即使因 機械力而被彎折，只要其後在伸展衣服的方向上施加作用 力，彎折的部分就會展開，皺褶消失。 隨著乾燥程序的進行，當棉纖維内的水分減少時，棉 纖維彼此的結合力增強。結果，棉纖維變得難以移動。一 旦機械力作用於水分少的棉纖維，棉纖維被彎折，棉纖維 就容易維持著被彎折的狀態。 隨著乾燥程序的進一步進行，棉纖維内的水分變得更 少。之後，即使在伸展棉纖維的方向上施加作用力，棉纖 維依然會維持彎折的狀態，幾乎不伸展。此種狀態稱為「皺 褶的固著」。 因此，用於乾燥衣服之乾燥程序，一方面促使水分從 衣服蒸發，卻也得到因水分減少導致之衣服起皺的結果。 皺褶的固著越多，最終結果就形成不良的乾燥。。 在狹小的滚筒内，纖維發生彎折是不可避免的。因此， 為了減少皺褶，減少在滾筒内產生的衣服皺褶數以及造成 皺褶強力固著之纖維的急遽彎折（銳角的彎折角度）是必要 的。若纖維發生彎折的地方隨後就被展開，另一方面其他 部位的纖維又發生彎折，則即使在狹小的滾筒内，也能減 少衣服上皺褶的產生。乾燥程序的期間，纖維彎折的地方 宜頻繁地變動。如果乾燥程序進行著，纖維中的水分逐漸 減少，則即使將已經伸展的纖維彎折的力起作用，新皺褶 的產生也會因為纖維間的強結合力而受到抑制。 23 201215732 。根據以上的研究，敵稍產生的容易度會對應衣服的乾 衣服（最容易產生賴的衣服) 為基準，說明容易產生皺褶的乾燥率。 “在、.勺85%至約1〇〇〇/。的乾燥率範圍内皺指最容易固 /別疋’棉纖維製的衣服如果乾燥率在約9〇ΰ/。到約 的範圍’衣服的皺褶最容易固著。再者，以下的數式表示 乾燥率。 【數1】 乾燥率（％)=(標準的衣服質量/含有水分之衣服的質 量)χ1〇〇 再者，所稱「標準的衣服質量」意指，在氣溫初·^且 濕度65%的條件下達成平衡之衣服質量。 連結1件衣服的乾燥斑來說明衣服的皺褶。 即使在1件衣服上也會產生乾燥斑。衣服並不會均勻地 乾燥，而是會產生乾燥延遲的區域。例如，長袖襯衫的腋 下部分，乾燥最慢。 通常’因為上述的乾燥斑，乾燥完成時之乾燥率的目 標值會設定成超過1〇〇%的值（例如，乾燥率：1〇2%〜 105%)。在該等目標值之下，如果衣服被均勻地乾燥，衣服 就過度乾燥。 以下的說明中，從剛脫水到約90%的乾燥率的範圍， 稱為「初期乾燥區域」。如上所述，在初期乾燥區域，衣服 的皺褶難以被固著。從約9〇%到約10〇%的乾燥率的範圍， 稱為「中間乾燥區域」。在中間乾燥區域，比較易發生皺褶 ⑧ 24 201215732 固 著。超過顏乾燥率的範圍，稱為「終期乾燥區域」。 如上所述，在終期乾燥區域，衣服的皺褶__著。 …本實樣中，间壓且高速的乾燥空氣，在中間乾燥 t域期間，是從第2風路U的第2吹出口 H)被送出。從第2風 服士 1第2°人出口

的消費電力’就可料成錢空氣之較高的流量。 在終期乾燥區域中，第丄風路9被利用作為乾燥空氣的 循環路徑。第1風路9因為乾燥空氣流動的流路之斷面積 大，所以乾燥空氣之壓力損失比較小。大流量的乾燥空氣 從形餘水槽2的底部之第^被吹出，接觸衣服。 攸乾燥程序的開始時刻起之經過時間如果超過第 定時間’控㈣7G即㈣風路切換部12的驅動馬達23，^ 第3圖所示地’開啟第1風路9。另外，控制部70會控制送風 部4，降低風機馬達4b的旋轉數。之後，直到乾燥程序 為止，控制部騎持續開啟第1風路9。因為通過第以 之乾燥Μ賴力損失小，所以控制㈣可以將風 扑的旋轉數設㈣比較低。如此’送風部4以少許的電力^ 28 201215732 費就被驅動。而，送風部4可以達成比較高的乾燥空氣流 量。因此，終期乾燥區域的乾燥時間縮短。另外，在終期 乾燥區域中所消費的電力量也減少。 本實施態樣中，控制部70基於從乾燥程序的開始時刻 起之經過時間（第1設定時間及第2設定時間），判定乾燥程序 中的「初期乾燥區域」、「中間乾燥區域」及「終期乾燥區 域」。然而，對應於收容在滾筒1之衣服的量，乾燥程序全 體的期間及「初期乾燥區域」、「中間乾燥區域」及「終期 乾燥區域」各自的期間會變動。因此，控制部70宜根據檢 測滾筒1中的衣服量之檢測部的檢測結果，對判定「初期乾 燥區域」、「中間乾燥區域」及「終期乾燥區域」時所使用 的第1設定時間及第2設定時間做調整。 檢測部15也可以在洗滌程序開始之前，檢測被投進滾 筒1之衣服的量（質量）。例如，檢測部15檢測支撐空的水槽2 (尚未對水槽2内供水，且，衣服未被投進滾筒1)之減震器14 的軸141的位置和，洗滌程序開始之前（對水槽2供水之前） 且衣服已投進滾筒1内時之減震器14的軸141的位置的差 異。軸141的位置差異的相關資訊，被當作投進滾筒1之衣 服的量的相關資訊輸出給控制部70。如此，控制部70就可 以根據軸141的位置的差異，判定滾筒1内的衣服的量。 投進滾筒1之衣服的量越多，控制部70根據檢測部15的 檢測結果設定的第1設定時間及第2設定時間就越長。結 果，「初期乾燥區域」、「中間乾燥區域」及「終期乾燥區域」 的期間對應於滚筒1内衣服的量，適當地被設定。控制部可 29 201215732 在對應滚筒1内的衣服的量而適當地被設定之第1設定期間 及第2設定期間的基礎上，在第丨風路9和第2風路u之間切 換乾燥空氣的循環路徑。 以下將說明風路切換部12的動作。 控制部70對驅動馬達23施加驅動脈衝。驅動馬達23沿 對應於所施加之驅動脈衝的方向旋轉.驅動馬達23的驅動 力被傳達到安裝於馬達旋轉軸23a之第1齒輪22a。之後，驅 動馬達23的驅動力再被傳達到與第丨齒輪22a嚙合之第2齒 輪22b。 弘S弟i菌輪22a及第2齒輪22b的減速齒輪22 … 的減速比使驅動馬達的旋轉數減速。結果，用於驅動遮: 21的扭矩增大。安裝於第2齒輪22b之遮板21以足夠的扭 做雙向旋轉。因此，起因於遮板21和第丨風路9的内面之 夾入異物之遮板21的卡住現象，會因為對應減速齒輪。 減速比而設定得比較高之扭矩而得到抑制。因此，遮板: 可以適當地轉動。在減速齒輪22之適當的減速比下，幾 不會發生不能控制遮板21的位置的情況。 由習知之洗衣乾衣機進行對乾燥空氣循環路徑的切: 控制’會因為異物而出現阻礙。例如，不能選擇所需要1 循環路徑’或者，發生空氣制。本實施態樣之洗衣乾1 機500，如上所述，因為對遮板21起作用的是高扭矩 不易受異物影響。因此’很難發生習知之洗衣乾衣機所 含的上述阻礙。 因此’本實施態樣之洗衣乾衣易受異物影響 ⑧ 30 201215732 而且幾乎不會發生遮板21卡住或空氣洩漏之類的阻礙。因 此，本實施態樣之洗衣乾衣機500可以在高信賴性下，切換 乾燥空氣的循環路徑。本實施態樣之洗衣乾衣機5〇〇因為具 有用於切換乾燥空氣的循環路徑之高信賴性的構造，所以 洗衣乾衣機500可以長時間維持高乾燥性能。 如第4圖所示，因為轉動到遮蔽第丨風路9的位置為止之 遮板21的遮蔽部21c的周緣(上緣21χ、下緣21y及前端緣以冗) 抵接凸肋28，所以第丨風路9被適當地遮蔽。因此，很難發 生空氣從第1風路9洩漏的情形。如此，達成了高信賴性且 高效率之乾燥空氣的循環。 在乾燥空氣的循環方向，凸肋28相對於遮板21係配設 在下游。因此，利用接觸遮板21之乾燥空氣的壓力遮^ 21被壓向凸肋28。如此，遮板21容易地被密接於凸肋μ。 ，’、°果，在遮板21和凸肋28之間難以發生空氣流出的現象。 因此，凸肋28兼具作為用以將遮板21固定在預定位置之擋 止的功能和，與遮板21合作將第丨風路9封閉之封閉功能。曰 如第4圖所示，遮蔽第1風路9之遮板21和第丨風路9的延 伸方向之間的角度設定在50度〜55度的範圍。結果，通過 第1風路9和第2風路11之間的分歧部的彎曲部之乾燥空氣 的壓力損失會適當地降低。另外，在分歧部的彎曲:淤 你二虱流路的斷面積維持在適當大小。因此，乾燥空氣可 以通過、緩緩f曲的循環路徑，往從^風路9分歧的第二風路 11流入。 第圖是表現導引風路24的内部構造之概略斜視圖。 31 201215732 第13圖為第12圖所示的導引風路24的凸肋28的周圍的擴大 斜視圖。用第3圖、第4圖、第8圖、第12圖及第13圖說 肋28。 第3圖、第4圖及第8圖所示的凸肋28形成略呈c字型的 突出輪廓。結果，凸肋28會抵接遮板21之考蔽部21c的上緣 21x、下緣21y及前端緣21z。或者，如第12圖及第13圖所示’ 抵接前端緣21z之凸肋28的部分亦可省略。例如，當遮板以 在遮蔽第1風路9的位置時，離遮板21的轉動軸最遠之前端緣 21z ’也可以抵接導引風路24的側壁。結果，即使缺了對應 刖知緣21z之凸肋28的部分，第1風路9依然被適當地遮蔽。 如第12圖及第13圖所示，導引風路24宜具備從導引風 路24的側壁向内突出之突出壁61。突出壁61相對於遮蔽第工 風路9之遮板21，在乾燥空氣的循環方向’是位在上游。遮 板21前端緣21z與導引風路24之間的乾燥空氣的通過，受到 遮板21前端緣21z所抵接或鄰接之導引風路24的側壁上所 形成之突出壁61的抑制。本實施態樣中，突出壁61是突出 部的例示。另外，形成突出壁61之側壁的面為内面的例示。 若形成突出壁61，那麼不在遮板21的前端緣212安裝襯 墊之類的密封部件亦可。即使遮板21的前端緣21z和導引風 路24的側壁之間存在小小的間隙，也會因為在乾燥空氣的 循環路徑，形成於遮板21的上游之突出壁61接觸流動的乾 燥空氣，所以乾燥空氣難以流入遮板21的前端緣2iz和導引 風路24的側壁之間的小小間隙内。因此，突出壁61適當地 減低通過遮板21的前端緣21z和導引風路24的側壁之間的 ⑧ 32 201215732 小小間隙之空氣洩漏。 突出壁61被形成為不妨礙遮板21轉動的狀態。因為前 端緣21z和突出壁61之間設有若干間隔，所以轉動中之遮板 21的前端緣21z不會接觸突出壁61。 第14圖為表現導引風路24的内部構造之概略斜視圖。 第15圖為第14圖所示之導引風路24的凸肋28的周圍的擴大 斜視圖。用第14圖及第15圖說明凸肋28。 導引風路24也可以具備從連接第2風路11的側壁向内 方突出之飛越臺62°比起遮蔽第2風路u之遮板21的前端緣 21z ’飛越臺62在乾燥空氣的循環方向形成於較上游。而 且’飛越臺62鄰接遮蔽第2風路u之遮板21的前端緣212。 被送去循環的乾燥空氣受到飛越臺62的傾斜面導引而飛越 遮板21的前端緣21Z。本實施態樣中，飛越臺62係例示為突 出部。另外，形成有飛越臺62的側壁的面係例示為内面。 飛越臺62從導引風路24的内面之突出量，被設定成大 於遮板21的遮蔽部2】.c之前端緣2iz的厚度。例如，遮蔽部 21c的刖端緣21z的厚度如果約為2 mm，則飛越臺62的突出 量設定在例如約2.5 mm〜約3 mm亦可。飛越臺62使乾燥空 氣難以流入遮板21的前端緣2iz與導引風路24的側壁之間。 遮蔽第2風路11之遮板21的遮蔽部21c的面，與乾燥空 氣的流動方向大致平行。儘管第2風路11會被遮板21的遮蔽 部21c堵住，但是在飛越臺62不存在下，被送去循環的乾燥 空氣有時還是會流入遮板21的前端緣21z與導引風路24的 側壁之間。乾燥空氣流入遮板21的前端緣21z與導引風路24 33 201215732 的側壁之間’有時會導致遮板21從導引風路24的側壁疏 遠。結果，在飛越臺62不存在下’被送去循環的乾燥空氣 有可能流入第2風路11。 如果形成飛越臺62，因為乾燥空氣會通過相對於遮板 21在乾燥空氣的循環方向形成於上游的飛越臺62，所以可 以飛越遮板21的前端緣21z。因此，乾燥空氣難以直接接觸 遮板21的前端緣21z。此結果，被送去循環的乾燥空氣幾乎 不會進入遮板21的前端緣21z與導引風路24的側壁之間。如 此，就不容易發生乾燥空氣不必要的流入第2風路η。 飛越臺62比起遮板21的前端緣21 z在乾燥空氣的循環 方向形成於上游。飛越臺62因為不會干擾遮板21的轉動， 所以封閉第2風路11之遮板21的前端緣21z和飛越臺62之間 的間隔’也可以設定成比遮板21的前端緣212與突出壁61的 間隔狭窄。 如第3圖所示’本實施態樣中，在分歧部的第丨風路9的 斷面積（乾燥空氣流路的斷面積），比第2風路1丨的斷面積 大。或者，在分歧部的第1風路的斷面積（乾燥空氣流路的

適當设定，抵擋妨礙遮蔽部件轉動之異物，遮蔽部件的轉 動得以持續。因為切換機構具有遮蔽部件不易卡住之構 造，所以遮蔽部件可以繼續進行適切的動作，流體則被適 切地引導向第1送風路徑或第2送風路徑。如此，切換機構 就具有1¾信賴性。 上述構成中，切換機構在前述分歧部還具備向内突出 之抵接部，前述遮蔽部件則宜包含，在遮蔽前述第丨送風路 徑及刖述第2送風路徑當中的至少一個時會抵接前述抵接 部的緣部。

air without drying clothes to the drum through the air passage. Dry air contacts the clothes that are put into the drum and draws water from the clothes. As a result, the clothes were properly dried. As described above, the dry air that has been in contact with the clothes is highly wet because it draws moisture from the clothes. The high-humidity dry air is discharged to the air path outside the drum. In particular, since a drying procedure is applied to the clothes in a narrow drum space, various methods for uniformly drying the clothes in a short time have been considered (for example, Japanese Laid-Open Patent Publication No. 2008-259549). Fig. 16 is a schematic view showing a main part of a conventional drum type washer-dryer described in Japanese Laid-Open Patent Publication No. 2008-259549. As shown in Fig. 16, the drum type washing and drying machine of the prior art is provided with a switching valve 1〇2. The switching valve 1〇2 is used to switch the air supply path of the dry air sucked in by the blower 1〇1. The conventional drum type washer-dryer controls the switching valve in a drying process, and the dry air is dried at a constant speed, and the dry air is blown from the front side of the vicinity of (4) open (four) to the inside of the roll. In addition, during the deceleration drying process, the washer-dryer blows the dryer from the crucible "back rear side outlet" into the drum. As a result of 201215732, the clothes are evenly dried in a short time. The above-described drum type washer-dryer has a (four) changing mechanism formed by a member (e.g., a valve) that closes the air passage. The city agency will appropriately (four) change the air supply path for dry air. For example, the switching mechanism opens another air supply path while using the valve-to-winding path. With this result, you can select the desired air supply path. ..., and the above-described cutting has a problem of controlling the switching of the air blowing path in a stable manner. For example, if the valve of the switching mechanism is caught with foreign matter, the valve will be stuck and the position of the valve cannot be properly controlled. If the switching control of the air supply path is not performed properly, there is a case where the required air supply path cannot be selected. Or, there is a case where air leaks from the air supply path (4). As a result, the drying performance is drastically reduced. As a result, the drying time becomes longer and the power consumption is also increased. In addition, there are cases where dry spots or wrinkles occur on the clothes. After washing, the valley is prone to occur. In particular, a fibrous or other foreign matter is present in a clothes dryer or a washer-dryer. Therefore, the above foreign matter is caused to be stuck and the air is leaked. C. Contents of the Invention] Summary of the Invention The present invention has an object of providing a switching mechanism having a high degree of reliability or difficulty in air leakage, a dryer, and a washer-dryer. In the aspect of the invention, the rotating mechanism has a first air blowing path through which the gripping body and the first air blowing path are different from each other, and the second air blowing path through which the fluid 201215732 passes and the wire in the air blowing path The bifurcation between the two different parts is driven by the driving of the second member, and the reduction gear is transmitted by the shielding; characterized in that the shielding member is described above!

C Embodiment; j is the best for implementing the invention In the following, a drum type washer-dryer according to an embodiment will be described with reference to the drawings. Further, the drawings and the details in the following description will be described in detail. The configuration is merely an example, and is not limited to the principle of the switching mechanism, the dryer, and the washer-dryer. (Configuration of the washer-dryer) Fig. 1 is a side view of the drum-type washer-dryer according to an embodiment. The washing and drying machine described below is also an example of a clothes dryer. The washing and drying machine 500 shown in Fig. 1 is provided with a cylindrical 6 6 201215732 drum 1 for storing laundry. The drum is opened at the front. The drum 丨 has a bottom surface opposite to the opening. In the embodiment, the drum 丨 is an example of the accommodating portion. The washing and drying machine 500 further includes a cylindrical water tank 2 for storing the washing water. The drum 1 is supported at Inside the water tank 2. The washing and drying machine 5 further includes a drive motor 3 attached to the back surface of the water tank 2. The drive motor 3 rotates the drum 1. The red shaft of the roll 1 is tilted upward toward the front. The washer-dryer 500 further includes a door 35 that is opened and closed by a user. The door 35 forms an opposite direction to the opening of the drum 1. When the user opens the door 35, the laundry (clothing) can be taken out and placed in the drum 1. The washer-dryer 500 has a water supply pipe (not shown) installed in the water tank 2 and a water supply valve (not shown) installed in the water supply pipe. When the water supply valve is opened, water is supplied to the water tank 2 through the water supply pipe. The washer-dryer 5 further has a drain pipe 4〇 connected to the water tank 2, and a drain valve 41 installed in the drain pipe 4〇. When the drain valve 41 is opened, water is discharged from the water tank 2. The washer-dryer 500 is provided with a blower unit 4 for circulating dry air for drying clothes. 4 ( (4) W dry Μ gas from the washings to extract water and high extinction. In the present embodiment, dry air is an example of a fluid. The discharge port 5 is formed in the water tank 2. The dry air is discharged to the outside of the water tank 2 through the discharge port 5 located around the circumference of the drum i. The washer-dryer 500 further includes a dehumidifying unit 6 for dehumidifying the dry air and a heating unit 7 for heating the dry air. The wetted portion 6 is dehumidified by the drying of the discharge port 5. Dry air that has been dehumidified by the dehumidifying unit 6: The hot air unit 7 201215732 The washing and drying machine 500 further includes a first air path 9 for guiding dry air and a second air path 11 for diverging from the first air path 9. The heated dry air is guided to one of the first air passage 9 or the second air passage 11. Thereafter, the dry air flows into the drum 1 again. In the present embodiment, the first air passage 9 is an example of the first air passage. The second air passage 11 is an example of the second air passage. The first air passage 9 includes a first air outlet 8 that is open at the rear of the drum 1 and the second air passage Π includes a second air outlet 1 that communicates with the opening of the drum 1. The first air outlet 8 of the first air passage 9 has a larger area than the second air outlet 10. Therefore, the pressure loss of the dry air flowing along the first air passage 9 is smaller than the pressure loss of the dry air flowing along the second air passage 11. Therefore, a larger amount of dry air flows into the drum 1 from the first outlet 8 . Since the second air outlet 1 is smaller than the sectional area of the first air outlet 8 , the dry air blown from the second air outlet 1 流入 flows into the drum 1 at a higher pressure and higher speed than the dry air blown from the first air outlet 8 . Inside. In the front side portion of the washer-dryer 500, the gap between the drum 1 and the sink 2 should be designed to be as small as possible. This makes it difficult for the clothes to enter the gap between the drum 1 and the water tank 2. A large air outlet (a small air outlet having a small pressure loss) like the first air outlet 8 is not easily provided in a narrow gap between the drum 1 and the water tank 2. However, since the second air outlet 1〇 has a smaller area than the second air outlet 8, the narrow gap between the drum 1 and the water tank 2 is set on the second air outlet 10 where the high-pressure and high-speed dry air is blown out. Can be applied as appropriate. In the rear side portion of the washer-dryer 500, a first air outlet 8 having a large opening area is formed on the bottom surface of the wider water tank 2. The washing and drying machine 5 has a cover body 36 covering the first air outlet 8 . The body 36 is formed with a plurality of small holes for allowing the air to flow in 201215732. Therefore, the cover body 36 as a whole has a large aperture ratio. The cover 36 prevents the clothes from entering the first air outlet 8. The first blowing port 8' formed on the bottom surface of the water tank 2 reaches the inflow of dry air having a small pressure loss. In the present embodiment, the rotation axis of the drum 1 is inclined upward toward the front. During the rotation of the roller, the small clothes such as socks, handcuffs, and short chins tend to be biased to the bottom surface of the drum 1. On the other hand, long-sleeved underwear, long underwear, long pomelo lining or long-sleeved pajamas are easily biased toward the front of the drum 1. When the user mixes the small clothes and the long clothes into the drum cymbal, the large amount of dry air blown from the first air outlet 8 near the bottom of the drum 1 is first contacted with a small amount of unevenly distributed at the bottom of the drum 1. Clothing. Thereafter, the dry air flashes over the long clothing type in which the small laundry is unevenly distributed in the front portion of the drum 1. Therefore, the small clothes and the long clothes are effectively dried together. Less wrinkles are produced on the small clothes that are dried as described above. Since the long clothes are easily twisted due to the agitation in the drying, the long clothes are more likely to wrinkle than the small clothes. As described above, since the long clothes are easily distributed unevenly in the front side region of the drum 1, the dry air blown from the second air outlet 10 can be dried more quickly than the dry air blown from the first air outlet 8. . Further, as described above, since the dry air blown from the second air outlet 10 is high-pressure and high-speed, the dry air blown from the second air outlet 10 appropriately spreads the long clothes, and can be placed on the drum 1 Moved inside greatly. As a result, the dry air blown from the second air outlet 1 can reduce the wrinkles which occur on the long clothes. The branching portions of the first air passage 9 and the second air passage 11 are formed downstream of the air blowing portion 4. The washer-dryer 500 further includes an air passage switching unit 12 that is disposed at a branching portion of the first air passage 9 and the second air passage 201215732 11. The air passage switching unit 12 switches the passing path of the dry air to one of the first air passage 9 and the second air passage 11 . As a result, the dry air sent from the air blowing unit 4 is supplied to the drum mode by one of the first air passage 9 and the second air passage n, and the air passage switching unit 12 is an example of the switching mechanism. The air passage switching unit 12 includes a shutter 21 that is rotatably pivotally coupled to the blade portions of the first air passage 9 and the second air passage U, and a drive portion that rotationally drives the shutter 21. The shutter 21 is rotated upright. When the second air passage 11 is closed (the shutter 21 indicated by the symbol "a" in Fig. 1), the first air passage 9 is opened. Therefore, the dry air sent from the blower unit 4 passes through the first air passage 9. When the shutter 21 is inclined in a transverse state with respect to the flow of the dry air sent from the blower unit 4, when the first air passage 9 is closed (the shutter 21 shown by the symbol "b" in Fig. 1), 2 Wind path 11 is opened. Therefore, the dry air sent from the air blowing unit 4 passes through the second air passage 11. The air passage switching unit 12 will be described later. The washer-dryer 500 also has a circulation air path 13 that defines a circulation path of dry air. The blower unit 4, the air passage switching unit 12, the dehumidifying unit 6, and the heating unit 7 are disposed in the circulation air passage 13. One end of the circulation air passage 13 is connected to the water tank 2, and a discharge port is formed. The dry air in the drum 1 is discharged from the discharge port 5, and then passes through the dehumidifying portion 6 and the heating portion 7. The blower unit 4 sends the dry air that has passed through the heating unit 7 to the drum 1 again. The air passage switching unit 12 determines the path of the dry air after the air blowing unit 4. When the air passage switching unit 12 allows dry air to flow to the first air passage 9, the dry air flows into the drum bore through the first air outlet 8. When the dry air is allowed to flow to the second air passage u, the air passage switching unit 12 flows into the drum 1 through the second air outlet 10. Therefore, the dry air will circulate in the washing machine 201215732. The dry air heated by the heating unit 7 disposed in the heating unit 7 and the air passage switching unit 12 is sent down along the circulation air path 13; 1 The f 4 is provided with a fan 4a and a fan material that allows the fan to rotate. Wind path == 12 If the path of the 1st-year gas is switched to the ninth, the wind of the air supply unit 4 gives the clear a_, so that the air-to-air reach of the ventilating windway 9 is set to be higher than the second pass. The flow rate of the dry air of the wind path u is more than the predetermined air volume. When the air path_portion 12 switches the path of the drying line to the second air path U, the fan motor of the air blowing unit 4 allows the fan 4a to rotate, so that the dry air (four) speed of the second air path 11 reaches the set state. The flow rate of the dry air of the air path 9 is faster than the predetermined wind speed. For example, if the flow rate of the dry air passing through the second outlet 8 is about 1 (m)/s, the flow rate of the dry vacant rolling through the second outlet 10 may be set to be about 5 〇 m/s or more. Further, if the flow rate of the dry air in the second air outlet 1 is higher than the flow rate of the dry air in the second air outlet 8, the flow rate of the dry air passing through the first air outlet 8 and the second air outlet 1 It can also be set to other values. The drum type washer-dryer according to the present embodiment is such that the flow rate of the dry air passing through the jth air passage 9 is larger than that of the air passing through the second air passage 1〇. Further, the 'drying and drying machine 5' is such that the flow rate of the dry air passing through the second air outlet of the second air passage is higher than the speed of the dry air passing through the first air outlet 8. Further, in the "drying machine", the air passage switching unit 12 is operated during the drying process, and the loop path of the dry air is switched between the first air passage 9 and the second air passage u. The discharge port 5 is formed at a position farther from the first air outlet 10 than the first air outlet 8 by 201215732 (that is, the discharge port 5 is formed closer to the vicinity of the second air outlet 10 than the first air outlet 8). . Therefore, the discharge port 5 is formed at the front of the drum 1, not the rear of the drum 1. The discharge port 5 may be formed in the vicinity of the second blowing port 1〇 disposed in front of the drum 1. As a result, the distance between the discharge port 5 and the first outlet port 8 becomes relatively long. The discharge port 5 is formed above the drum 1. Thus, the dry air that has been in contact with the clothes is effectively discharged upward. Further, the principle of the present embodiment may be applied to a discharge dryer for discharging dry air from the drum 1 if it is applied to a drum type dryer having no washing function, and may not be formed above the drum. In the present embodiment, the "drying and drying machine 500" washes the laundry with washing water. Therefore, in order to prevent the inflow of the washing water into the discharge port 5, the discharge port 5 is formed above the water level of the washing water. The second outlet 10 provided in front of the drum 1 is opened in the upper region of the drum 1. Therefore, with the rotation of the drum 1, the high-pressure and high-speed dry air is effectively blown against the clothes floating upward. Thus, the dry air blown from the second outlet 10 can effectively reduce the wrinkles generated on the clothes. The washer-dryer 5 has a shock absorber 14 disposed below the water tank 2. The damper 14 supports the water tank 2. In the case where, for example, 'the clothes are dehydrated, the clothes are unevenly distributed in the drum 1', the weight distribution of the drum 1 is unbalanced. The imbalance of the weight distribution of the drum 1 causes the vibration of the water tank 2 when the roll 1 is rotated. The damper 14 appropriately attenuates the vibration of the water tank 2. The damper 14 is provided with a shaft 141 that moves up and down in accordance with the weight of the clothes in the water tank 2. The washer-dryer 500 further includes a detecting unit 15 that detects the amount of clothes in the water tub 2 based on the amount of displacement of the shaft 141. The detecting portion 15 is mounted on the damper 14 of 5 12 201215732. The drum type washer-dryer 500 of this embodiment is of a heat pump type, and dehumidifies and heats the dry air. The washer-dryer 500 is provided with a heat pump device 50. The hot spring device 50 is provided with a compressor 16 for compressing a refrigerant, a radiator 17 for compressing the high-temperature and high-pressure refrigerant, and a pressure-reducing portion 18 for reducing the pressure of the high-pressure refrigerant and The pressure reducing portion 丨8 is reduced to a low pressure refrigerant to extract the surrounding heat heat absorber 19, and is connected to the compressor 16, the radiator 17, the pressure reducing throttle portion 18, and the heat pipe 19 of the heat pipe 19. The refrigerant circulates along the pipe 20. The heat absorber 19 is used as the above-described dehumidifying unit 6. Further, the radiator 17 is used as the heating unit 7. In the present embodiment, the drum type washer-dryer 5 〇〇 uses the heat pump device 5 进行 to dry the clothes. The principles of this embodiment can also be applied alternatively to devices having other configurations for drying clothes. For example, dry air is also dehumidified by a water-cooling device that sprays dry air directly. In addition, heaters are used to heat dry air. Fig. 2 is a schematic block diagram of a drum type washer-dryer 5 。. The washer-dryer 500 will be described using Figs. 1 and 2. The washer-dryer 500 includes a control unit 7A and an input setting unit 32. The user inputs the setting information regarding the operation of the washer-dryer 5 in the input setting unit 32. The control unit 7G monitors a series of operation operations of the silk dryer, the rinsing, the dehydration, and the drying based on the setting information while monitoring various conditions of the washing and drying machine 500 that operates according to the setting information. For example, in the drying program, the control unit 70 controls the number of rotations of the drive motor 3 by the motor drive power (four). In addition, the control (4) 7G controls the air supply unit 4 and the green unit 5 (10) operation, and adjusts various parameters such as the flow rate, temperature, and humidity of the dry air in 201215732. Further, the control unit 70 controls the air passage switching unit 12 to selectively switch the flow path of the dry test gas between the first air passage 9 and the second air passage 11. The control unit % may also include, for example, a CPU (Central Processing Unit) (not shown), and store the program ROM (Read 〇nly M_ry), and store the program or the RAM (Rand()m when performing various processes. Ae(10)Me_y) enters the turn-out interface' and the bus that connects them. The control unit 70 is provided with a timer 71. The timer 71 sets the second set time and the second set time. The first set time and the second set time are described later. The timing H71 may be, for example, an internal timer included as part of the internal power of the control (four)% execution operation. Alternatively, the timer may be a timing device of a different form from the control unit. The washer-dryer 500 of this embodiment has a single first blowout outlet 8. Alternatively, the washer-dryer can also have a plurality of third blowing outlets. Similarly, the washer-dryer 5 has a single second outlet 1 〇. Alternatively, the washer-dryer may have a plurality of second outlets. 3 and 4 are schematic perspective views of the air passage switching unit 12. Fig. 5 is a schematic view of the shutter 21. The air passage switching unit 12 will be described with reference to the fifth to fifth figures. As described above, the air passage switching unit 12 is attached to the branch portion between the first air passage 9 and the second air passage 11. In the present embodiment, as shown in the third, third, and fourth figures, the first air passage 9 linearly extends from the air blowing portion 4. The second wind road u differs from the ninth wind road. In the present embodiment, the second air path n is divided at an angle of a nearly right angle (approximately 90 degrees) to the second air passage 9. Alternatively, the angle of the second wind path to the second wind path may be other values. 14 201215732 As described above, since the first air passage 9 for guiding the dry air having a relatively large flow rate linearly extends from the air blowing portion 4, the pressure loss of the dry air flowing along the first air passage $ is small. The dry air having a large flow rate is efficiently sent from the first wave path 9 to the drum 1. As shown in FIGS. 3 and 4, the first air passage 9' for guiding the dry air having a relatively large flow rate has a larger sectional area than the second air passage U for guiding the dry air flowing at a high speed ( The area of the cross-sectional area where dry air is allowed to flow). In the present embodiment, as shown in FIGS. 3 and 4, the cross-sectional shape of the first air passage 9 is not circular but around the branch portion of the i-th air passage 9 and the second air passage U. Nearly rectangular. Since the cross-sectional shape of the air path 9 around the branch portion is close to the moment, the material of the first air path 9 is flat. Therefore, other parts are easily attached to the flat peripheral wall of the hurricane 9 . In the present embodiment, the cross-sectional shape of the fine matter around the branching portions of the first air passage 9 and the second air passage u is close to _. Alternatively, the cross section of the first air passage 9 around the branch portions of the second air passage 9 and the second air passage 11 may have other shapes. For example, the cross section of the first air passage 9 around the branch portions of the first air passage 9 and the thin road u may be formed in a nearly circular shape. Fig. 6 and Fig. 7 are schematic plan views of the guide air passage for guiding the dry air from the air blowing portion 4 to the branch portions of the air passage and the air passage _. The guide air passage will be described with reference to Fig. 1 and Fig. 3 to Fig. 7.

The housing member 25 includes a first housing wall 25a shown in Fig. 6 and a second housing wall 25b shown in Fig. 7. Each of the first housing wall 25a and the second housing wall 2513 includes a joint portion 25c that protrudes outward, and the first housing wall 25a overlaps the second housing wall 25b' with a suitable joining member such as a bolt, and the joint portion 25c is attached. Engage. The blower 4a of the blower unit 4 is housed in an internal space formed by the first storage wall 253 and the second storage wall 25b which are overlapped. A first guide air passage 26 that is used as a part of the first air passage 9 is disposed downstream of the housing member 25. The above-mentioned branching portion is formed on the positive side of the first guiding air passage %. As shown in Fig. 6, the guide air passage 24 further includes an air passage piece 26a formed integrally with the i-th housing wall 25a and an air passage piece 26b integrally formed with the second housing wall 25b. The air passage piece 26a is superposed on the air passage piece 26b, and forms a section from the accommodating portion 25 to the branch portion directly in front of the first guide air passage 26. In the present embodiment, as shown in Fig. 6, the second housing wall 25a and the air passage piece 26a are formed of a material such as synthetic resin. Further, as shown in Fig. 7, the second housing wall 2513 and the air passage piece 26b are integrally molded of a material such as synthetic resin. The air passage pieces 26a and 26b and the first housing wall 25a and the second housing wall 25b are provided with the joint portion 25c. The air passage piece 26a is overlapped with the air passage piece 26b, and the joint portion is joined by a suitable joint member such as a bolt, and a section from the storage member 25 to the front (four) branch portion of the first guide air passage 26 is formed. . Further, the upper portion of the branch portion shown in Fig. 3 corresponds to the wind path piece 26a described in Fig. 6. Further, the lower portion of the branch portion shown in Fig. 3 corresponds to the air passage piece 26b described in Fig. 7. As shown in Figs. 6 and 7, the guide air passage % has ribs 28 projecting from the inner faces of the air passage pieces 26a and 26b, respectively. When the wind path sheets 26a and 26b are heavy #, 201215732 is raised into the ribs 28 of the wind path piece 26a and the ribs 28 formed on the air path piece 26b to form a substantially C-shaped protruding contour. The first air passage 9 extends further downstream from the first guide air passage 26 until it is formed in the first air outlet 8 of the water tank 2. As shown in Fig. 6, the air passage piece 26a is formed with a second guide air passage 27 which is used as a part of the second air passage 11. As shown in FIG. 3, the divided air passage switching unit 12 provided between the first air passage 9 and the second air passage 11 includes a shutter 21, a reduction gear 22, and a drive motor 23 for driving the shutter 21. , ribs 28. The shutter 21 selectively shields one of the first air passage 9 and the second air passage 11. The shutter 21 that shields the second air passage 11 is shown in FIG. As a result, the dry air is circulated through the first air passage 9. Fig. 4 shows the shutter 21 which shields the second air passage 9. As a result, the dry air is circulated through the second air passage 丨1. As shown in Fig. 5, the shutter 21 includes a rotating shaft portion 21a that is attached to the branch portion between the first air passage 9 and the second air passage 11, and a gear mounting portion 21b that is provided at the upper end of the rotating shaft portion 21a. The shielding portion 21c fixed to the rotating shaft portion 21a. The shielding portion 21c selectively shields one of the first air passage 9 and the second air passage 11. In the present embodiment, the shielding portion 21c is an example of a shielding member. The shutter 21 is formed of, for example, a material such as synthetic resin. The shielding portion 21c of the shutter 21 includes an upper edge 21x, a lower edge 2iy, and a front end edge 21z. The size and contour of the upper edge 21x, the lower edge 21y, and the front end edge 21z are determined by the cross-sectional shape of the branch portion of the guide air passage 24. The shielding portion 21 c of the shutter 21 has an area larger than the sectional area of the second air passage 11 connected to the branch portion. As shown in Fig. 3, the shielding portion 21c which is formed at a position orthogonal to the second air passage 11 is disposed, and the second air passage η is completely shielded. 17 201215732 The shielding portion 2ic of the shutter 21 is formed to be slightly smaller than the cross section of the first air passage 9, so as to be rotated in the branch portion formed in the guiding air passage 24. A gap is formed between the upper edge 21x and the lower edge 2ly of the shielding portion 2lc and the inner surface of the first air passage 9. The excessively narrow gap between the upper edge 21x and the lower edge 21y and the inner surface of the second hurricane 9 is not only too high for the accuracy of the women's wear, but also tends to cause foreign matter to be caught in the gap, and therefore, the shielding portion 21c The gap between the upper edge 21x and the lower edge 21y and the inner surface of the first air passage 9 may be set to be approximately 丨5. As shown in Fig. 3, Fig. 6, and Fig. 7, a rib 28 is formed on the inner surface of the hurricane path 9. The rib 28 abuts against the end edges (the upper edge 21 χ, the lower edge 21 丫, and the front end edge 21 ζ) of the shielding portion 21 c of the shutter 21 . The rib 28 is formed downstream of the shielding portion 21c of the shutter 21 in the flow direction of the dry air. As shown in Fig. 4, when the shutter 21 is rotated to shield the second air passage 9, the end edges (the upper edge 21x, the lower edge 21y, and the front end edge 21z) of the shielding portion 2U abut against the ribs 28. As a result, the hurricane 9 is completely sealed by the shielding portion 21 c and the rib 28 . Fig. 8 schematically shows the contact of the shutter 21 and the ribs 28. Further, Fig. 8 schematically shows a section along the line A-A shown in Fig. 4. The abutment of the shutter 21 and the rib 28 will be described with reference to Figs. 4 and 8. The amount of protrusion of the rib 28 is too large (the amount of protrusion from the inner surface of the i-th air passage 9)', and the result is that the air resistance is large. Therefore, the amount of protrusion of the rib 28 is preferably set to, for example, about 2 mm. The gap between the edge (the upper edge 21x, the lower edge 21y, and the front edge 21z) of the shielding portion 21c of the shutter 21 and the inner surface of the first air passage 9 is set to about 1. 5 mm, the ribs with a protrusion of about 2 mm "the overlap with the shielding portion 2lc is about 〇·5 mm. About 0. The overlap of 5 mm is sufficient for sealing the first air passage 9. Further, the amount of protrusion of the rib 28, the gap between the shutter 21 and the inner surface of the 18 8 201215732, and the numerical value of the amount of overlap are examples, and other values may be set for these size parameters. The angle Θ shown in FIG. 4 means the angle of rotation of the shutter 21 from the shielding position of the second air passage 11 to the shielding position of the first air passage 9 (or with respect to the first air passage 9) The direction of extension, the angle formed by the shielding portion 21e of the ribs 28 abutting the ribs 28, in the embodiment, the angle is set to about 50 degrees. The angle Θ is set to an angle less than 9 degrees (this embodiment) In the case of the pressure loss caused by the collision between the dry air flowing to the second air passage u which is different from the second wind passage 9 and the shielding portion 21c of the shutter 21, it is known that it is relatively small ( When the angle Θ is set to 90 degrees, the flow path of the dry air that is gradually curved toward the second air passage 11 is formed. Thus, the dry air efficiently flows into the second air passage 11. In the present embodiment, The angle Θ is set to an angle greater than 45 degrees (about 50 degrees in the present embodiment). Since the angle θ is set to a value greater than 45 degrees, the flow path of the dry air bent toward the second air passage 11 is The sectional area becomes larger than when the angle Θ is set to 45 degrees. In this embodiment, it is considered that it is formed in the first wind. The pressure loss at the corner portion of the branch portion between the 9th and the second air passage 11 and the sectional area of the flow path of the dry air are set at a range of 5 to 55 degrees to cover the first air passage. The rib 28 downstream of the shutter 21 of the slab 21 is substantially flush with the shielding portion 21c of the shutter 21. The splicing portion 2 ing edge (the edge 21 χ, the lower edge 21 y and the front end edge 21 z) of the shielding plate 21 is in the pair The shielding position of the first air passage 9 is in contact with the rib 28 without a gap. It is preferable to provide a sealing member such as a ring-shaped ring in the contact portion between the shielding portion 11c of the shutter 21 and the rib u. The air leakage from the shielding portion 21c of the shutter 21 and the rib 28 can be attached to one of the shielding portion 21c and the rib 28 of the shutter 21 in the sealing member of the type 201215732. A schematic perspective view of the guide air passage 24. The mounting of the shutter 21 will be described with reference to Figs. 3 to 6 and Fig. 9. The rotating shaft portion 21a of the shutter 21 disposed inside the first air passage 9 One end portion is rotatably pivotally connected to the guide air passage 24. The other end side of the rotation shaft portion 21a penetrates through the mounting hole 24a of the guide air passage 24 (see FIGS. 6 and 9). can The gear mounting portion 21b is provided at the end of the rotating shaft portion 21a that protrudes outside the first hurricane 9 through the through-hole 24a (see Fig. 5). Fig. 3 and Fig. 4 The second gear 22b of the reduction gear 22 is attached to the gear attachment portion 21b. The reduction gear 22 that transmits the driving force of the drive motor 23 to the shielding portion 21c includes the first gear 22a (cylindrical spur gear) and The second gear 22b (divided into a sector spur gear) that is meshed with the first gear 22a > j. The first gear 22a is smaller than the diameter of the second gear 22b. The first gear 22a is used as a pinion (small gear) . The first gear 22a is attached to the motor rotating shaft 23a of the drive motor 23. The rotational power of the drive motor 23 is directly transmitted to the first gear 22a. Further, the power transmission from the drive motor 23 to the first gear 22a may be achieved by using another power transmission mechanism unlike the above-described direct transmission method. The second gear 22b that meshes with the first gear 22a rotates in accordance with the rotation of the first gear 22a. Therefore, the first gear 22a is used as a drive gear, and the second gear 22b is used as a driven gear. In the following description, the number of teeth of the first gear 22a (drive gear) is given the symbol "Z1". On the other hand, the number of teeth of the second gear 22b (passive gear) is given a symbol of 8 20 201215732 "Z2". The reduction ratio of the reduction gear 22 is expressed as Z2/Z1. In the following description, the number of rotations of the first gear 22a (drive gear) is given a sign of "N1". On the other hand, the number of rotations of the second gear 22b (passive gear) is given a sign of "N2". The reduction ratio of the reduction gear 22 is expressed as N1/N2. The driving torque of the shutter 21 attached to the second gear 22b is adjusted in accordance with the reduction ratio of the reduction gear 22. As described above, with the combination of the drive motor 23 and the reduction gear 22, a sufficiently large driving torque of the shutter 21 can be obtained. The driving torque of the shutter 21 is preferably set to, for example, that the shutter 21 is not caught by the foreign matter being caught between the shutter 21 and the first air passage 9. Fig. 10 is a schematic enlarged perspective view of the periphery of the branching portion of the first air passage 9 and the second air passage 11. The driving of the shutter 21 will be described with reference to Figs. 2 to 4 and Fig. 10. As shown in Fig. 10, the first gear 22a and the second gear 22b are covered by the gear cover fitting 29. The gear cover fitting 29 suppresses foreign matter from entering the meshing portion of the second gear 22& and the second gear 22b, and suppresses foreign matter from entering the first air passage 9. In the present embodiment, the drive motor 23 is a stepping motor that can rotate in both directions. The control unit 7〇 described in Fig. 2 applies a drive pulse to the drive motor 23, and adjusts the amount of rotation (rotation angle) of the drive motor 23. As a result, the action of the shutter 21 is appropriately controlled. As shown in Fig. 3, when the shutter 21 is driven to the shielding position toward the second air passage, the control unit 70 applies an excessive number of pulses to the drive motor 23 to generate a plurality of overtravels. Thus, when the shutter 21 abuts against the "face" around the second air passage U, a constant pressure is applied to the shutter 21. Thereby, the shutter 21 can appropriately shield the second air passage. 21 201215732 As shown in Fig. 3, a restricting rib 3 is formed on the outer surface of the guide air passage 24. The restriction rib 30 abuts against the right end portion 22c of the sector-shaped second gear 22b, and restricts the rotation of the second gear 22b in the counterclockwise direction. Therefore, the shutter 21 hardly generates excessive counterclockwise rotation. Similarly, as shown in Fig. 4, when the shutter 21 is driven to the shield position of the hurricane path 9, the control portion 70 applies an excessive number of pulses to the drive motor 23 to generate a plurality of overtravels. Thus, when the shutter 21 abuts against the rib 28, a predetermined amount of pressure is applied to the shutter 21. Therefore, the shutter 21 can appropriately shield the first air passage 9. As shown in FIG. 4, a restricting rib 31 is formed on the outer surface of the guide air passage 24. The restriction rib 31 abuts against the left end portion 22d of the sector-shaped second gear 22b, and restricts the clockwise rotation of the second gear 22b. Therefore, the shutter 21 hardly produces an excessive clockwise rotation. The restriction ribs 3A and 31 are formed by recessing the upper portion of the corner of the branch portion of the first air passage 9 and the second air passage 11. (Operation of Washing and Drying Machine) The operation and advantageous effects of the above-described drum type washing and drying machine will be described below. The above-described washer-dryer 500 reduces the wrinkles of clothing produced during the drying process. In a narrow drum, the clothes are dried in a state in which they are not fully extended. Therefore, many wrinkles are usually produced on clothes that are dried in a narrow drum. This incident caused dissatisfaction to the user. In particular, clothes with a lot of cotton produce a lot of wrinkles. Therefore, if the amount of cotton is increased, the final result after drying tends to be deteriorated. 22 201215732 During the presence of moisture in the cotton fibers, the cotton fibers move relatively freely with each other. Therefore, even if the clothes agitated with the rotation of the drum are bent by mechanical force, as long as a force is applied in the direction in which the clothes are stretched, the bent portion is unfolded, and the wrinkles disappear. As the drying process proceeds, as the moisture in the cotton fibers decreases, the bonding strength of the cotton fibers to each other increases. As a result, the cotton fibers become difficult to move. Once the mechanical force acts on the cotton fibers with less moisture, the cotton fibers are bent and the cotton fibers are easily maintained in a bent state. As the drying process proceeds further, the moisture in the cotton fibers becomes less. Thereafter, even if a force is applied in the direction in which the cotton fibers are stretched, the cotton fibers are maintained in a bent state and hardly stretched. This state is called "fixation of wrinkles." Therefore, the drying process for drying clothes, on the one hand, promotes the evaporation of moisture from the clothes, but also results in wrinkles of the clothes caused by the reduction in moisture. The more the wrinkles are fixed, the end result is poor drying. . In a narrow drum, bending of the fibers is unavoidable. Therefore, in order to reduce wrinkles, it is necessary to reduce the number of wrinkles of the clothes generated in the drum and the sharp bending of the fibers which strongly restrain the wrinkles (the bending angle of the acute angle). If the fiber is bent and then unfolded, and the fibers of other parts are bent, the wrinkles on the clothes can be reduced even in a narrow drum. During the drying process, the areas where the fibers are bent should be changed frequently. If the drying process is carried out and the moisture in the fibers is gradually reduced, even if the force of bending the already stretched fibers acts, the generation of new wrinkles is suppressed by the strong bonding force between the fibers. 23 201215732. According to the above research, the ease of generation of the enemy will be based on the dry clothes of the clothes (the clothes most likely to be produced), and the drying rate at which wrinkles are likely to occur will be described. "in,. Spoon 85% to about 1 〇〇〇 /. In the range of drying rate, the wrinkles are the easiest to fix / don't 疋 'cotton fiber clothes if the drying rate is about 9 〇ΰ /. To the extent of the appointment, the wrinkles of the clothes are most likely to be fixed. Further, the following formula indicates the drying rate. [Number 1] Drying rate (%) = (standard clothes quality / quality of clothes containing moisture) χ 1〇〇 Again, the term "standard clothes quality" means, at the beginning of temperature and humidity of 65%. Achieve a balanced quality of clothing under conditions. Connect the dry spots of one piece of clothing to illustrate the wrinkles of the clothes. Dry spots are produced even on one piece of clothing. The clothes do not dry evenly, but rather create areas of dry delay. For example, the underarm portion of a long-sleeved shirt is the slowest to dry. Usually, the target value of the drying rate at the time of completion of drying is set to a value exceeding 1% by the dry spots (for example, drying rate: 1〇2% to 105%). Below these target values, if the clothes are evenly dried, the clothes are overly dry. In the following description, the range from the just dehydration to a drying rate of about 90% is referred to as an "initial drying zone". As described above, in the initial drying area, the wrinkles of the clothes are hard to be fixed. The range of drying rate from about 9% to about 10% is referred to as "intermediate drying zone". In the middle dry area, wrinkles are more likely to occur. 8 24 201215732 Fixation. The range exceeding the drying rate of the skin is called the "final drying area". As mentioned above, in the final dry area, the wrinkles of the clothes are __. In the present example, the dry air having a high pressure and a high speed is sent out from the second air outlet H) of the second air passage U during the intermediate drying period t. From the 2nd Windshield 1st 2nd person's exit 1〇 The high-pressure and high-speed dry air that was sent out effectively reduced the wrinkles of the clothes by 4 in the middle of the clothes. In the oil drying zone and the period from the gas field to the first time, the first air outlet 8 of the relatively large flow rate dry air passage 9 is supplied. By switching the supply path of the dry air between the power saving unit and the second air path 11 in the drying process, the "initial drying zone drying/drying zone" and the "end period" specified in the field 2 are determined. The dry ship domain can also be based on the control unit 7. According to the dry push: the local application mode, it is determined that the drying program falls in the "end time and the "end period & dry season", "intermediate dry area", 4 #L New Area" That -" Winding road switching section 丨 /. The control unit 7G controls the passage of the air based on the determination result. The dry air is switched between the road 9 and the second air passage 11, and the control unit 7 ◦ prestores the distress period for the execution period of the drying program. If the elapsed time from the start of drying is not exceeded by the control unit 7G, the drying program is judged to be in the initial drying zone. The control unit 7 〇 prestores the second set period set for the execution period of the drying program. Further, the second set period is set to a value larger than the second set period. The elapsed time of the drying sequence is from the first set time to the second set time 25 201215732. The drying unit 1 judges that the drying unit 1 is surrounded by the control unit 7G, that is, if the elapsed time of the drying program in the inter-drying area = exceeds the second setting, the control unit _ drying order is in the final drying area. During the drying process, the control unit 70 appropriately switches the path of the dry air with the second air passage 11 based on the above determination result. The first fruit 'h uses a single-ventilating portion 4, and the wrinkles of the clothes are reduced by abundance*b, '° as described above, in the initial drying zone and the intermediate drying zone; one period, relatively large flow drying The air is supplied from the first breeze of the hurricane road. When the dry air of a relatively large flow rate is supplied from the first air outlet 8 and the high-speed dry air is supplied from the second air outlet 10, the laundry dryer 5 of the present embodiment is consumed, and at a high pressure. And the device that supplies the air at idle speed, and the air that is dry, or in addition to the high-pressure and high-speed dry air, is also provided with a plurality of fans for additionally increasing the air volume. The total amount of electricity consumed. In this way, the Benz-style washing and drying machine 500 can achieve good drying results with less power consumption and almost no wrinkles. Figure. Figure 11 is an illustration of the time to switch the path of the dry air. The first step to the fifth and eleventh figures illustrate the cutting of the path of the dry air after the start of the drying process until the first setting is passed. Dry air is supplied to the drum 1 from the first air passage 9 in the initial drying zone up to the time. Since the second air passage 9 has a large sectional area for the flow of the dry air, the pressure loss of the dry air is small. The large-flow dry air supplied through the first air passage 9 is blown out from the first air outlet 8 formed at the bottom of the water tank 2 to contact the clothes. The control unit 7〇& 26 201215732^the motor 23 is the same as the first position: the shielding unit 2 and the second air path u. As a result, the first timer 71 starts the measurement program, and the control unit 70 uses 匕' and the elapsed time from the start of the main sequence. Straight: factory. Continue to open the i-th wind road 9. Because the pressure loss through the first: is relatively small, w is set to whistle „=do 7 fighters (four) rotating the flow of dry air for a little power, then you can give the big to 1, 1, (6),. Because the big stream (four) dry air is supplied. "5 '卩 Drying time in the initial drying zone is shortened. The amount of electricity consumed in the initial drying zone is also reduced. The elapsed time from the start of the drying process is 6 or more. The P70 determines that the drying process is entered. In the intermediate drying area air (four), the first few roads, the control unit 7 turns the fan motor 4b to rotate. As a result, in the intermediate drying area, the dry air is blown from the second blowing port 1 (W into the drum i. @ is the second blowing) σ 1G The flow path of the dry air flow is smaller than the first air outlet 8', so the drying from the second air outlet (7) becomes high pressure and high speed. Second, the elapsed time from the start of the drying program exceeds the first setting. The control unit 70 controls the drive motor 23 of the air passage switching unit 12, and as shown in Fig. 4, the shielding portion 2ie of the shutter 2 abuts against the rib 28. As a result, the first air passage 9 is closed. The second air passage 11 is opened. Thereafter, the control unit 7 controls the air supply to increase the number of rotations of the motor 4b. The control unit 7 直到 until the elapsed time from the start of the money program 27 201215732 exceeds the second set time. Keep on The second air passage 11 is opened. In the intermediate drying area, the clothes are unfolded because of the high-pressure and high-speed dry air, and the wrinkles of the clothes are reduced. The elapsed time from the start of the drying process exceeds the second set time 'control unit 7G, it is determined that the drying program enters the final drying area. The control unit 7 controls the road (4) (4) drive motor η, and switches the dry air path to the first air path 9. As described above, in the final dry area, the clothes Contains less moisture. Dry air contacts a small amount of moisture in the clothes towel, so that it takes a long time to evaporate water from the clothes. Therefore, supplying a large amount of dry air to the drum will increase the moisture in the clothes appropriately. The chance of dry air contact. Moreover, because the dry air is supplied to the drum raft through the hurricane road 9, the relatively low power consumption can be used to generate a higher flow rate of the air. In the final dry area, The hurricane road 9 is utilized as a circulation path of dry air. The first air passage 9 has a large flow area due to the flow of dry air, so the pressure loss of the dry air is compared. A large flow of dry air is blown out from the bottom of the shape of the shape of the water tank 2 to contact the clothes. The elapsed time from the start of the drying process is more than the predetermined time 'control (4) 7G, that is, the drive motor of the (four) air passage switching portion 12 23, ^ As shown in Fig. 3, the first air passage 9 is opened. The control unit 70 controls the air blowing unit 4 to reduce the number of rotations of the fan motor 4b. Thereafter, the control unit rides on until the drying process. Wind path 9. Because the loss of the drying force by the first is small, the control (4) can set the number of rotations of the wind flap to be relatively low. Thus, the air supply unit 4 is driven with a small amount of electricity. The air blowing portion 4 can achieve a relatively high dry air flow rate. Therefore, the drying time in the final drying region is shortened. In addition, the amount of electricity consumed in the final dry area is also reduced. In the present embodiment, the control unit 70 determines the "initial drying zone", the "intermediate drying zone", and the "drying zone" in the drying process based on the elapsed time (the first set time and the second set time) from the start time of the drying process. The final dry area." However, the period corresponding to the clothes accommodated in the drum 1 varies during the entire period of the drying process and during the "initial drying zone", "intermediate drying zone", and "final drying zone". Therefore, the control unit 70 should preferably determine the "first dry area", the "intermediate dry area", and the "end dry area" based on the detection result of the detection unit of the amount of clothes in the drum 1 and the first set time and the 2 Set the time to make adjustments. The detecting unit 15 may detect the amount (mass) of the clothes thrown into the drum 1 before the start of the washing process. For example, the detecting unit 15 detects the position of the shaft 141 of the damper 14 supporting the empty water tank 2 (the water supply has not been supplied to the water tank 2, and the clothes are not thrown into the drum 1) and before the washing process starts (water supply to the water tank 2) Before) and the difference in the position of the shaft 141 of the damper 14 when the clothes have been thrown into the drum 1. The information on the difference in the position of the shaft 141 is output to the control unit 70 as information on the amount of the clothes to be fed into the drum 1. Thus, the control unit 70 can determine the amount of clothes in the drum 1 based on the difference in the position of the shaft 141. The larger the amount of clothes thrown into the drum 1, the longer the first set time and the second set time set by the control unit 70 based on the detection result of the detecting unit 15. As a result, the period of "initial drying zone", "intermediate drying zone" and "final drying zone" corresponds to the amount of clothes in the drum 1, and is appropriately set. The control unit 29 can switch the dry air between the first air passage 9 and the second air passage u in addition to the first setting period and the second setting period which are appropriately set corresponding to the amount of clothes in the drum 1 Loop path. The operation of the air passage switching unit 12 will be described below. The control unit 70 applies a drive pulse to the drive motor 23. The drive motor 23 rotates in a direction corresponding to the applied drive pulse. The driving force of the drive motor 23 is transmitted to the first gear 22a attached to the motor rotating shaft 23a. Thereafter, the driving force of the drive motor 23 is again transmitted to the second gear 22b that meshes with the second pin gear 22a. The reduction ratio of the reduction gear 22 of the second S-wheel 12a and the second gear 22b decelerates the number of rotations of the drive motor. As a result, the torque for driving the cover 21 is increased. The shutter 21 attached to the second gear 22b is rotated in both directions with sufficient twist. Therefore, the jamming phenomenon of the shutter 21 in which the foreign matter is sandwiched between the shutter 21 and the inner surface of the first air passage 9 is caused by the corresponding reduction gear. The torque is set to a relatively high speed and is suppressed. Therefore, the shutter: can be rotated properly. At the appropriate reduction ratio of the reduction gear 22, the position where the shutter 21 cannot be controlled does not occur. Cutting the dry air circulation path by a conventional washer-dryer: Control 'because of foreign matter obstruction. For example, you cannot select the 1 cycle path required or the air system occurs. The washing machine 1 of the present embodiment is as described above because the high torque is applied to the shutter 21 and is not easily affected by foreign matter. Therefore, it is difficult to cause the above-mentioned obstacles contained in the conventional washing and drying machine. Therefore, the laundry dryer of the present embodiment is susceptible to foreign matter 8 30 201215732 and there is almost no obstruction such as jamming of the shutter 21 or air leakage. Therefore, the washer-dryer 500 of the present embodiment can switch the circulation path of the dry air with high reliability. The washer-dryer 5 of the present embodiment can maintain high drying performance for a long time because of the highly reliable structure for switching the circulation path of the dry air. As shown in FIG. 4, since the peripheral edge (the upper edge 21χ, the lower edge 21y, and the front end edge of the shielding portion 21c of the shutter 21 that is rotated to the position where the second air passage 9 is shielded is abutted against the rib 28, the rib 28 is abutted. The second hurricane road 9 is appropriately shielded. Therefore, it is difficult to cause air to leak from the first air passage 9. In this way, a cycle of dry air with high reliability and high efficiency is achieved. In the circulation direction of the dry air, the ribs 28 are disposed downstream with respect to the shutter 21. Therefore, the pressure of the dry air contacting the shutter 21 is pressed against the ribs 28. Thus, the shutter 21 is easily adhered to the rib μ. , ', a fruit, a phenomenon in which air escaping hardly occurs between the shutter 21 and the ribs 28. Therefore, the rib 28 has both a function as a stopper for fixing the shutter 21 at a predetermined position and a closing function for closing the hurricane passage 9 in cooperation with the shutter 21.曰 As shown in Fig. 4, the angle between the shutter 21 that shields the first air passage 9 and the direction in which the first air passage 9 extends is set in the range of 50 to 55 degrees. As a result, the pressure loss of the dry air passing through the curved portion of the branch portion between the first air passage 9 and the second air passage 11 is appropriately lowered. In addition, the bending of the divergence section: the area of the gap of your second turbulent flow path is maintained at an appropriate size. Therefore, the dry air can pass through and slowly circulate the path of the f curve, and flows into the second air path 11 which is branched from the air path 9. The figure is a schematic perspective view showing the internal structure of the guide air passage 24. 31 201215732 Fig. 13 is an enlarged perspective view showing the periphery of the rib 28 of the guide air passage 24 shown in Fig. 12. The ribs 28 are illustrated in Figs. 3, 4, 8, 12 and 13. The ribs 28 shown in Figs. 3, 4, and 8 form a substantially c-shaped protruding profile. As a result, the rib 28 abuts against the upper edge 21x, the lower edge 21y, and the front end edge 21z of the masking portion 21c of the shutter 21. Alternatively, the portion of the rib 28 that abuts against the front end edge 21z as shown in Figs. 12 and 13 may be omitted. For example, when the shutter is at the position where the first air passage 9 is shielded, the end edge 21z' can be abutted against the side wall of the guide air passage 24 before being farthest from the rotation axis of the shutter 21. As a result, even if the portion corresponding to the rib 28 of the rim 21z is missing, the first air passage 9 is appropriately shielded. As shown in Figs. 12 and 13, the guide air passage 24 is preferably provided with a projecting wall 61 projecting inward from the side wall of the guide air passage 24. The projecting wall 61 is located upstream with respect to the shutter 21 which shields the wind path 9 in the circulation direction of the dry air. The passage of the dry air between the front end edge 21z of the shutter 21 and the guide air passage 24 is suppressed by the projecting wall 61 formed on the side wall of the guide air passage 24 where the front end edge 21z of the shutter 21 abuts or abuts. In the present embodiment, the protruding wall 61 is an example of a protruding portion. Further, the surface on which the side wall of the protruding wall 61 is formed is an example of the inner surface. If the protruding wall 61 is formed, a sealing member such as a gasket may not be attached to the front end edge 212 of the shutter 21. Even if there is a small gap between the front end edge 21z of the shutter 21 and the side wall of the guide air passage 24, the protruding wall 61 formed upstream of the shutter 21 contacts the flowing dry air in the circulation path of the dry air. Therefore, it is difficult for the dry air to flow into the small gap between the front end edge 2iz of the shutter 21 and the side wall of the guide air passage 24. Therefore, the protruding wall 61 appropriately reduces the air leakage through the small gap of 8 32 201215732 between the front end edge 21z of the shutter 21 and the side wall of the guide air passage 24. The protruding wall 61 is formed in a state that does not interfere with the rotation of the shutter 21. Since a plurality of spaces are provided between the front end edge 21z and the projecting wall 61, the front end edge 21z of the shutter 21 in rotation does not contact the projecting wall 61. Fig. 14 is a schematic perspective view showing the internal structure of the guide air passage 24. Fig. 15 is an enlarged perspective view showing the periphery of the rib 28 of the guide air passage 24 shown in Fig. 14. The rib 28 will be described with reference to Figs. 14 and 15. The guide air passage 24 may include a flying table 62 that protrudes inward from the side wall that connects the second air passages 11 and a front end edge 21z that shields the second air passage u from the front end edge 21z'. The circulation direction is formed upstream. Further, the 'flying-over stage 62 is adjacent to the front end edge 212 of the shutter 21 that shields the second air path u. The dry air sent to the circulation is guided by the inclined surface of the flying table 62 and flies over the front end edge 21Z of the shutter 21. In the present embodiment, the flying platform 62 is exemplified as a protruding portion. Further, the surface on which the side wall of the flying table 62 is formed is exemplified as an inner surface. The amount of protrusion of the flying platform 62 from the inner surface of the guiding air passage 24 is set to be larger than the shielding portion 2 of the shutter 21. The thickness of the end edge 2iz before c. For example, if the thickness of the end edge 21z of the shielding portion 21c is about 2 mm, the amount of protrusion of the flying table 62 is set to, for example, about 2. 5 mm to about 3 mm is also available. The flying table 62 makes it difficult for the dry air to flow between the front end edge 2iz of the shutter 21 and the side wall of the guide air passage 24. The surface of the shielding portion 21c that shields the shutter 21 of the second air passage 11 is substantially parallel to the flow direction of the dry air. Although the second air passage 11 is blocked by the shielding portion 21c of the shutter 21, in the absence of the flying platform 62, the dry air sent out for circulation sometimes flows into the front end edge 21z of the shutter 21 and guides the wind. Between the side walls of the road 24. The flow of dry air into the front end edge 21z of the shutter 21 and the side wall of the guide air passage 24 33 201215732 sometimes causes the shutter 21 to be alienated from the side wall of the guide air passage 24. As a result, the dry air that has been sent to the circulation in the absence of the flying table 62 may flow into the second air passage 11. If the flying table 62 is formed, since the dry air passes through the flying table 62 which is formed upstream in the circulation direction of the dry air with respect to the shutter 21, the front end edge 21z of the shutter 21 can be flying. Therefore, it is difficult for the dry air to directly contact the front end edge 21z of the shutter 21. As a result, the dry air sent to the circulation hardly enters between the front end edge 21z of the shutter 21 and the side wall of the guide air passage 24. As a result, it is less likely that dry air will flow into the second air passage η unnecessarily. The flying table 62 is formed upstream of the front end edge 21 z of the shutter 21 in the circulation direction of the dry air. Since the flying table 62 does not interfere with the rotation of the shutter 21, the interval ' between the front end edge 21z of the shutter 21 closing the second air passage 11 and the flying table 62 can be set to be larger than the front end edge 212 of the shutter 21. The spacing of the protruding walls 61 is narrow. As shown in Fig. 3, in the present embodiment, the cross-sectional area of the first air passage 9 (the sectional area of the dry air flow path) in the branch portion is larger than the sectional area of the second air passage 1丨. Alternatively, the sectional area of the first air passage (the sectional area of the dry air flow path) in the branch portion may be set to be substantially equal to the sectional area of the second air passage. Further, a rib that abuts against the shutter may be formed on the inner surface of the second air passage. The ribs and the louvers protruding from the inner surface of the second air passage can also be used to shield the second air passage. The principle of this embodiment has been explained by a drum type washer-dryer 500 having both a washing function and a clothes drying function. Alternatively, the principle of the embodiment can be applied to a dryer that does not have a washing function. The dryer which does not have a washing function may be, for example, a device which earns various elements of the washing ability by subtracting 5 from the roller clothes shown in Fig. 8 34 201215732. The clothes dryer may also be a device for removing the water supply pipe and the drain pipe connected to the water tank, for example, from the drum type clothes dryer shown in the figure. The water tank 2 can also be used as a groove outside the lining protection drum. The various other elements of the dryer are also similar, as are the laundry dryer 500 that has been made in the drawings. The principle of this embodiment has been explained by a drum type washing and drying machine having both a washing function and a clothes drying function. Alternatively, the principles of this embodiment can be applied to other types of devices. The principle of this embodiment is suitably applied to a device such as a clothes dryer and a washer-dryer having a configuration for switching a circulation path of dry air. The principle of this embodiment can also be applied to, for example, a device in which a garment is hanged in a casing or a device in which a pulsator is used to agitate clothes (for example, an upright washing and drying machine). The above embodiment mainly includes a clothes treating device having the following constitution. The switching mechanism having the following configuration and the clothes dryer and the washing and drying machine having the switching mechanism have a structure in which switching control failure due to foreign matter is not easily caught. In the above aspect, the switching mechanism includes a first air blowing path through which the blown fluid passes, and a second air blowing path that passes through the first air blowing path and is connected to the first air blowing path. a rotatable shielding member that is a branching portion between the air blowing path and the second air blowing path; a driving motor that drives the shielding member; and a reduction gear that transmits the driving force of the driving motor to the shielding member; The shielding member selectively shields one of the first air blowing path and the second air blowing path from 35 201215732. The fluid blown by the above configuration passes through the first air blowing path or the second air blowing path that is branched from the first air blowing path. The driving force of the driving motor is transmitted to the shielding member attached to the branching portion between the i-th air blowing path and the second air blowing path by the reduction gear, and the shielding member is rotated. As a result, the shielding member selectively shields one of the first air blowing path and the second air blowing path. As a result of transmitting the driving force via the reduction gear, the driving torque is adjusted in accordance with the reduction ratio of the reduction gear. Therefore, by appropriately setting the reduction ratio of the reduction gear, the foreign matter that hinders the rotation of the shield member is prevented, and the rotation of the shield member is continued. Since the switching mechanism has a configuration in which the shielding member is less likely to be caught, the shielding member can continue to perform an appropriate operation, and the fluid is appropriately guided to the first air blowing path or the second air blowing path. In this way, the switching mechanism has 13⁄4 reliability. In the above configuration, the switching mechanism further includes an abutting portion that protrudes inwardly, and the shielding member preferably includes the abutting when the at least one of the first air blowing path and the second air blowing path is blocked. The edge of the abutment. According to the above configuration, the edge portion of the shielding member abuts against the abutting portion in which the branch portion protrudes inward when at least one of the first air blowing path and the second air blowing path is shielded, so the mth wind path and the (2) of the 2 air supply paths are properly shielded. Therefore, the fluid is appropriately guided to the ith air supply path! Or the second air supply path. Thus, the switching mechanism has high reliability. In the above configuration, the abutting portion is preferably disposed downstream of the shielding member in the flow direction of the fluid. According to the above configuration, since the abutting portion is disposed downstream of the shielding member in the flow direction of the fluid, the contact member is subjected to the pressure of the fluid colliding with the shielding member, and the shielding member is appropriately adhered to the abutting portion. Therefore, the fluid is appropriately guided to the first air blowing path or the second air blowing path. In this way, the switching mechanism has high reliability. In the above configuration, the one path preferably includes an inner surface adjacent to the shielding member that shields the one path, and a protruding portion that protrudes from the inner surface, and the protruding portion is preferably disposed in the flow direction than the shielding member. More upstream. According to the above configuration, one path includes an inner surface adjacent to the shielding member that shields one path, and a protruding portion that protrudes from the inner surface. In the flow direction, the projections disposed upstream of the shield member make it difficult for fluid to flow between the inner surface and the shield member. Therefore, the fluid is appropriately guided to the first air blowing path or the second air blowing path. Thus, the switching mechanism has high reliability. According to another aspect of the invention, the dryer includes the switching mechanism and the accommodating portion for accommodating the clothes, and the drying air for drying the clothes as the fluid, and the first air supply is performed by the first air supply One of the path and the second air blowing path is sent to the air blowing portion of the accommodating portion, and the switching mechanism is controlled to selectively switch the flow path of the dry air between the first air blowing path and the second air blowing path. Control department. According to the above configuration, the air blowing unit sends the dry air for drying the clothes to the accommodating portion for accommodating the clothes through one of the first air blowing path and the second air blowing path. The control unit controls the switching mechanism to drive between the first air blowing path and the 37 201215732 second air blowing path because the switching mechanism maintains the drying performance. The flow path of the dry air is selectively switched. The washing and drying machine which can be used for the long-term aspect of the above-described yoke aspect is characterized in that the dryer and the above-mentioned housing portion and the sink for storing the washing water are provided. . According to the above configuration, the water tank contains the storage portion for storing the washing water. The laundry dryer has the above-mentioned dryer, so it can maintain the drying performance for a long time. [Industrial Applicability] The principle of this aspect can be suitably applied to various types of dryers or washer-dryers such as drum type, hanging type, and pulsator type.
