Description of the Invention: [Technical Field of the Invention] The present invention relates to improving the dewatering performance of a washing and drying machine. [Prior Art] Drying clothes are carried out by using a washing and drying machine that is continuously carried out from laundry to drying. A fan and a heat source are used to generate high-temperature and low-humidity air, and the air is blown into the washing tank. To make the temperature of the clothes high, so that the water evaporates from the clothes, and then the evaporated water is discharged to the outside of the machine. The method of removing the evaporated water includes: exhausting directly to the outside of the washing and drying machine (frequently supplying new air), and cooling and evaporating the water into water to remove moisture from the dehumidification. The method (to make the same air circulation) is generally used in households where the water is not discharged to the dehumidification system in which the laundry and clothes dryer is installed. There are several appeals for washing and drying machines: (1) shorter drying time, (2) less power consumption, (3) better drying effect (less pleats in clothing), and (4) clothing. Less damage, etc. Among them, regarding (1) and (2), there is a washing and drying machine which can effectively perform dry clothes by appropriately controlling the air volume and temperature of the air in accordance with the progress of the drying clothes. In addition, there is a washing and drying machine that allows the clothes in the washing tank to be fully turned over to efficiently evaporate water from the clothes. Further, there is a washing and drying machine which uses a water-cooling method as a dehumidification mode to make the cooling water flow on the entire wall surface of the air passage, and to improve the heat exchange efficiency with the hot air having a high temperature and a high humidity. Further, at the beginning of the operation of the dryer, the dehydration operation is carried out to sufficiently remove the water from the clothes. -5- 201014940 In relation to (4), there is a washing and drying machine equipped with a low-temperature drying stroke that does not excessively raise the temperature of the clothes, and limits the temperature of the hot air (inhibiting the input of the heater). Regarding (3), since the clothes are creased due to entanglement and twist in the clothes, there is a washing and drying machine which makes the clothes less likely to be twisted and twisted. [Patent Document 1] JP-A-2002-080946 (Patent Document 3) JP-A-2005-080946 (Patent Document 4) [Problem to be Solved by the Invention] In order to improve the dewatering performance during the dehydration operation, the following methods are known: (1) Increasing the rotational speed of the laundry and dewatering tanks of the input clothes, and increasing the centrifugal force. (2) Increase the temperature of the clothes in the dehydration. (3) A convex surface is provided on the groove wall surface of the dewatering and washing tank. (1) is the most common. However, the power consumption of the motor increases as the rotational speed increases, and even the dewatering performance tends to saturate in terms of the rotational speed. Therefore, when the rotation speed is increased, the power consumption of the entire drying operation is lowered. However, when the rotation speed is increased or higher, the power consumption is increased, and even if the rotation speed is increased beyond necessary, the power consumption cannot be lowered. The effect of power consumption. In addition, in order to rotate at a high speed, it is necessary to increase the strength of the washing and drying machine, so the cost will increase. (2) It can be achieved by blowing hot air into the washing and dewatering tank during dehydration. As long as the temperature of the clothes rises, the viscosity or surface tension of the water contained in the clothes will decrease, so the water content of the clothes will decrease. However, since the clothes in the dehydration are attached to the wall of the laundry and dewatering tank, it is difficult to blow the hot air to the entire garment. In addition, in order to generate hot air, it is necessary to supply electric power to the heat source, so power is consumed. (3) It is a method to reduce the water content of the clothes near the wall surface of the groove, and the higher the height of the convex surface, the better. In addition, it has the advantage of improving dewatering performance without increasing power consumption. However, since the convex surface reduces the effective volume of the washing and dewatering tank, the tumbling of the clothes during the drying operation after dehydration is deteriorated, and in order to improve the dewatering performance, the effect of reducing the power consumption is reduced, and the drying operation is performed. In terms of it, it is impossible to reduce power consumption. Here, the flow of the wind during dehydration of the general drum type laundry and clothes dryer will be described using Figs. 11 and 12. Figure 11 is a longitudinal section of the drum-type washer and dryer in the center of the front-rear direction.
A 洗衣兼脫水槽的底面圖。在洗衣兼脫水槽3的底壁3f係 設有通氣用的多數的貫通孔3dl。此外，複數條的凸狀肋 部11從底壁中心呈放射狀形成。第12圖係在滾筒式洗衣 暨乾衣機的左右方向的中央，朝縱方向予以剖斷的剖面圖 。第12圖（a)係顯示在脫水旋轉中，風扇單元運轉時之風 的流動，第12圖（b)係顯示風扇單元停止時之風的流動。 風的流動係以箭頭來表示。在風扇單元運轉時，從噴嘴流 入洗衣兼脫水槽3內的熱風會直接從貫通孔3dl朝外槽內 201014940 流出（箭頭A)，或者是利用凸狀肋部11的風扇作用，從底 壁3f的中心部被吸入，朝底壁3f的外緣側流動，吹到貼 附在洗衣兼脫水槽3之外周壁的衣類，再從貫通孔3dl朝 外槽內流出（箭頭B)。朝外槽流出的熱風係以從吸氣口 2a 被吸入至乾衣導管29，然後再經過過濾導管27(箭頭43) ，被吸入至送風扇28，再返回洗衣兼脫水槽內的方式循環 〇 另一方面，當風扇單元停止時，會因爲和上述同樣的 凸狀肋部11的風扇作用，而產生箭頭B的氣流。然後， ® 從貫通孔3dl朝外槽內流出之空氣的一部份，會在洗衣兼 脫水槽3之外周壁與外槽之內周壁之間的空隙，朝向洗衣 兼脫水槽的前側流動，又重回洗衣兼脫水槽內（箭頭D)， 其他的部份則從底壁之內周側的貫通孔又返回洗衣兼脫水 槽內（箭頭E)。因此，流動於衣類表面的風量就沒有太多 〇 本發明的目的爲提供一種不增加耗電，可提高脫水性 _ ❹ 能並降低乾衣運轉之耗電的洗衣暨乾衣機。 [用以解決課題之手段] 爲達成上述目的，本發明之特徴如下： 一種洗衣暨乾衣機，係具有：收容衣類的旋轉滚筒、 收容該旋轉滾筒，與旋轉滾筒配置在同芯上’儲存洗衣用 水的外槽、驅動上述旋轉滾筒的馬達、支撐上述旋轉滚筒 的筐體、以及將熱風供給至上述旋轉滾筒內的送11手段’ -8 - 201014940 執行乾衣運轉的洗衣暨乾衣機，其特徵爲··在上述旋轉滾 筒’於連接上述馬達轉軸的旋轉滾筒底壁面，具有從中央 呈放射狀延伸之複數條的凸狀肋部，並且上述底壁面的外 周部爲阻斷通氣的構成，或者是不設有通氣用的貫通孔。 此外，上述凸狀肋部的構成係對上述旋轉滾筒的旋轉方向 具有扭轉角。 再者，一種洗衣暨乾衣機，係具有：收容衣類的旋轉 滾筒、收容該旋轉滾筒，與旋轉滾筒配置在同芯上，儲存 洗衣用水的外槽、驅動上述旋轉滾筒的馬達、支撐上述旋 轉滾筒的筐體、以及將熱風供給至上述旋轉滾筒內的送風 手段，執行乾衣運轉的洗衣暨乾衣機，其特徵爲：在上述 旋轉滾筒，於連接上述馬達旋轉軸的旋轉滾筒底壁面，具 有從中央呈放射狀延伸之複數條的凸狀肋部，並且在上述 底壁面之半徑的一半以上的部份，係不設有通氣用的貫通 孔。 [發明效果] 如此構成的洗衣暨乾衣機，在乾衣初期一方面使旋轉 滾筒高速旋轉來進行脫水，一方面溫熱衣類的熱風脫水步 驟中，由凸狀肋部之旋轉所引起之風扇作用所產生的空氣 不會朝外槽流出，而會大量的流動在因爲離心力而貼附在 旋轉滾筒之筒體板部之衣類的表面，所以，除了可有效使 衣類加溫外，還可促進水份從衣類的表面蒸發，不須增加 脫水步驟時的耗電量，即可減低衣類的含水量。因此，可 9 - 201014940 降低乾衣運轉的耗電量，實現節約能源的要求。 【實施方式】 以下茲使用圖面，針對本發明的一實施形態來加以說 明。 第1圖係本發明之一實施形態之滾筒式洗衣暨乾衣機 的外觀圖。第2圖係爲了顯示內部構造，將筐體之一部份 予以剖斷所示的立體圖，第3圖係爲了顯示內部構造，將 背面蓋取下的背面圖，第4圖係顯示內部構造的側面圖， ®

體1，做爲筐體1係具有充分的強度。 9係將被設置在前面蓋lc之略中央，用來將衣類取出 置入之投入口予以關閉的門，被設於前補強材的鉸鏈，以 可開閉的方式所支持。藉由按下門開啓鍵9d，鎖定機構（ 無圖示）就會解除，門會開啓，而只要將門朝前面蓋lc按 壓’即可鎖定關閉。前補強材係與後述之外槽的開口部同 心，具有用來將衣類取出置入的圓形開口部。 -10- 201014940 6爲被設置在筐體1之上部中央的操作面板，具備： 電源開關39、啓動開關12、操作按鍵開關13、以及顯示 器14。操作面板6係與設在筐體1下部的控制裝置38電 連接。 3爲以可被旋轉支撐的圓筒狀洗衣兼脫水槽（旋轉滾筒 )，在其圓筒外周壁3e具有用來通水以及通風的複數個貫 通孔3d，在前側端面則設有用來將衣類取出置入的開口部 3a。在開口部3a的外側具有與洗衣兼脫水槽3呈一體的 流體平衡器3c。在洗衣兼脫水槽3的底壁3f係形成了從 中心朝外緣部延伸的複数條放射狀的凸狀肋部。在外周壁 3e的內側設有複數個朝軸方向延伸的升降桿3b，在洗衣 、乾衣時，一旦洗衣兼脫水槽3旋轉，衣類就會因爲升降 桿3b與離心力，沿著外周壁上昇，再因爲重力而落下， 重複如此的動作。洗衣兼脫水槽3的旋轉中心軸爲水平， 或者是以開口部3 a側變高的方式傾斜。 2爲圓筒狀的外槽，在同軸上內藏洗衣兼脫水槽3, 前面爲開口，在後側端面的外側中央裝設了馬達4。馬達 4的旋轉軸係貫穿外槽2，與洗衣兼脫水槽3之底壁3f的 中心結合。在前面的開口部設有外槽蓋2d，可朝外槽內儲 水。在外槽蓋2d的前側中央，具有用來將衣類取出置入 的開口部2c。本開口部2c與設於前補強材37的開口部， 係利用橡膠製的波紋管10連接在一起，藉由將門9關閉 即可將水密封於外槽2。在外槽2底面最下部設有排水口 2b，並連接著排水管26。在排水管26的中間設有排水閥（ -11 - 201014940 無圖示），關閉排水閥，進行供水，即可將水儲存在外槽2 ，打開排水閥則可將外槽2內的水朝機外排出。 外槽2係由下側被固定在基座lh的懸吊裝置5(由螺 旋彈簧與減振器所構成）所防振支持。此外，外槽2的上 側係由被裝設在上部補強構件的補助彈簧（無圖示）所支持 ，以防止外槽2朝前後方向傾倒。 19爲設置在筐體1內之上部左側的洗劑容器，裝設了 由前部開口拉出式的洗劑托盤7。在裝入洗劑類時，將洗 劑托盤7依第1圖之兩點虛線所示般拉出。洗劑容器19 ® 係被固定在筐體1的上補強材。 在洗劑容器19的後側，設置：供水電磁閥16、洗澡 水供水泵浦1 7、以及水位感測器（無圖示）等與供水相關的 零件。洗劑容器19係與外槽2連接。供水電磁閥16爲多 聯閥，1 6b爲主供水電磁閥，通過洗劑容器1 9，將洗衣水 供給至外槽2。16c爲柔軟劑供水電磁閥，通過洗劑容器 19朝外槽進行供水。16d爲冷卻水電磁閥，朝水冷除濕機 構（無圖示）進行供水。 ® 在上面蓋le設有來自水龍頭的供水管連接口 16a、以 及洗澡剩餘水的吸水管連接口 17a。 29爲朝縱方向設置在筐體1之背面內側的乾衣導管， 導管下部係利用橡膠製的伸縮管B29a與設置在外槽2之 背面下方的吸氣口 2a相連。在乾衣導管29內係內藏了水 冷除濕機構（無圖示），從供水電磁閥16將冷卻水朝水冷除 濕機構進行供給。冷卻水經過乾衣導管29的壁面流下， -12- 201014940 從吸氣口 2a進入外槽2，再從排水口 2b排出。 乾衣導管29的上部係與朝前後方向設置在筐體1內 之上部右側的過濾導管27相接。在過濾導管27的前面具 有開口部，拉出式的乾衣過濾器8係插入至該開口部。從 乾衣導管29進入到過濾導管27的空氣，會流入乾衣過濾 器8的網眼過濾器8a，而將棉屑去除。清理乾衣過濾器8 可將乾衣過濾器8拉出，將網眼式過濾器8a取出來進行 。此外，在過濾導管27的乾衣過濾器8揷入部的下面設 ® 有開口部，該開口部係與吸氣導管33連接，吸氣導管33 的另一端則與送風扇28的吸氣口相連。 送風扇28，係由：驅動用馬達28a、風扇葉輪（無圖 示）、以及風扇盒2 8b所構成。加熱器31係內藏於風扇盒 28b，對來自風扇葉輪的空氣進行加熱。送風扇28的吐出 口係與熱風導管30連接。熱風導管30係隔著橡膠製的伸 縮管A30a、伸縮管接頭30b，與設置在外槽蓋2d的熱風 吹出口 32相連。在本實施例中，送風扇28係設於筐體1 _ 內的上部右側，所以熱風吹出口 32就設在外槽蓋2d的右 斜上方的位置，使得與熱風吹出口 32之間的距離爲最短 〇 在排水口 2b、送風扇28的吸氣口以及吐出口設有溫 度感測器（無圖示）。 乾衣運轉時之風的流動如下所述。一旦使送風扇28 運轉，對加熱器31進行通電，高速的熱風就會從噴嘴3 2d 朝洗衣兼脫水槽3內吹入（箭頭41)，吹著濕潤的衣類，對 -13· 201014940 衣類加溫使水份從衣類蒸發。變成高溫多濕的空氣從設置 在洗衣兼脫水槽3的貫通孔朝外槽2流動，從吸氣口 2a 被吸入至乾衣導管29，在乾衣導管29從下往上流動（箭頭 42)。來自水冷除濕機構的冷卻水會在乾衣導管29的壁面 流下，因爲高溫多濕的空氣與冷卻水接觸而被冷卻除濕， 成爲乾燥的低溫空氣，再進入過濾導管27(箭頭43)。通過 設於過濾導管27的網眼過濾器8a將棉屑予以去除，進入 吸氣導管33，被吸入至送風扇28(箭頭44)。然後，被以 加熱器31再度加熱，被吹入洗衣兼脫水槽3內的方式循 © 環。在這過程中，洗衣兼脫水槽3係以低速正反向旋轉， 將衣類推高至噴嘴32d附近爲止，使高速的熱風可直接吹 到衣類。 利用第7圖來說明熱風脫水時之風的流動。第7圖（a) 係顯示使送風扇28運轉，對加熱器31通電，從噴嘴32d 將熱風吹入至洗衣兼脫水槽3內的情形，第7圖（b)係顯示 送風扇28停止時的情形。再者，風的流動係如圖中箭頭 所示。實際上，因爲洗衣兼脫水槽3正以高速旋轉，所以 ® 洗衣兼脫水槽3之旋轉方向的空氣雖有流動，但在此爲了 說明就省略該流動。又，在脫水中，衣類會因爲離心力而 貼附在洗衣兼脫水槽3之外周壁3e’呈甜甜圈狀。因此， 位在外周壁3e的貫通孔3d就會被衣類阻塞，所以從洗衣 兼脫水槽3之內側朝外側通過的空氣幾乎無法在貫通孔3d 流動。 首先，針對送風扇2 8運轉時的情形來加以說明。一 -14- 201014940 旦洗衣兼脫水槽3旋轉，形成於底壁3f的凸狀肋部Η就 會變成離心風扇。從噴嘴噴出的熱風（箭頭41)會從底壁3f 的中心被吸入，朝底壁3f的外緣側流動（箭頭45)°然後 ，對著貼附在外周壁3e的衣類吹，使流動方向略呈90度 彎曲，沿著衣類表面流動，一邊使衣類的溫度上昇’一邊 朝向洗衣兼脫水槽3的開口部3a流動。已到達洗衣兼脫 水槽3前側的空氣，從外槽蓋2d與流體平衡器3c的空隙 朝洗衣兼脫水槽3與外槽2的空隙流動’從吸氣口 2a被 Φ 吸入至乾衣導管29(箭頭46)。然後再通過過濾導管27(箭 頭43)，經過吸氣導管33，被吸入至送風扇28(箭頭44)。 再者，已到達洗衣兼脫水槽3前側的空氣的一部份，會以 再度吸入至底壁3f之中心的方式返流（箭頭47)。 接下來，針對送風扇2 8停止的情形來加以說明。此 種情形下，一旦洗衣兼脫水槽3旋轉’一樣會因爲凸狀肋 部11的離心風扇作用，空氣會從洗衣兼脫水槽3的底壁 3 f的中心部分被吸入，朝外緣側流動。然後，又如同上述 ^ ，對著貼附在外周壁3 e的衣類，改變流動方向，沿著衣 類表面朝向洗衣兼脫水槽3的開口部3a流動。已到達洗 衣兼脫水槽3前側的空氣，會以沿著門9，朝向洗衣兼脫 水槽3的中心流動，再被吸入至底壁3f之中心的方式循 環（箭頭48)。 如此一來，因爲熱風可確實地在衣類的表面流動，所 以可有效提高衣類的溫度。更進一步可促進衣類水分的蒸 發。因此，不須增加脫水轉數，也就是說不會增加耗電即 -15- 201014940 可降低衣類的含水量。 再者，因爲在洗衣兼脫水槽3的底壁3f並沒有貫通 孔，所以還具有以下的效果。滾筒式洗衣暨乾衣機的洗衣 方式爲使洗衣兼脫水槽3以低速旋轉，利用升降桿3b將 洗衣兼脫水槽3內的衣類上推落下，來進行洗衣。爲了將 濕潤的衣類往上推，驅動洗衣兼脫水槽3的馬達4就必須 具有低速、高轉矩的特性。一旦維持此種特性來進行脫水 運轉的話，雖然與洗衣時相較轉矩較低，但是若爲了使其 高速旋轉，轉矩就明顯不足。雖然可提高馬達4的驅動電 © 壓，使較多電流流動來進行轉矩提高的控制，但是因爲馬 達效率變低，馬達4就會發熱。一般而言，可用冷卻風扇 來加以冷卻，去除該熱度。在本發明中，可將馬達的發熱 有效地利用於脫水時。馬達4之發熱的一部份會透過馬達 4的旋轉軸4a傳導至洗衣兼脫水槽3的底壁3f。此時， 因爲底壁3f沒有貫通孔，底壁3f的熱傳導面積較大（熱阻 較小），所以來自馬達的熱可輕易傳導至洗衣兼脫水槽3 的外周壁3e，使外周壁3e的溫度上昇。因此，接觸到外 © 周壁3e之衣類的溫度也會上昇。 脫水係利用高速旋轉所產生的離心力，將水份從衣類 去除的作業。在脫水中，衣類係貼附在洗衣兼脫水槽3的 外周壁3e，含於衣類的水份從衣類的內側朝外周壁3e側 流動，從設於外周壁3e的貫通孔3d朝外槽2內排出。在 衣類的纖維內或纖維間具有細小的空隙，因爲進入到該部 份之水的毛細管作用’使水份保持在衣類內。一旦進行脫 -16- 201014940 水，該毛細管作用與離心力會產生平衡，而無法進一步去 除水份。因此’愈接近洗衣兼脫水槽3的外周壁3e，衣類 局部的含水量就愈多。雖然毛細管作用與水的界面張力呈 比例，但是一旦水溫上昇，界面張力就會降低’所以只要 提高衣類的溫度，就可減少含水量。如上所述，本發明係 可有效將馬達的發熱傳導至洗衣兼脫水槽3的外周壁3e， 所以可有效減低含水量較多之外周壁3e附近的衣類的含 水量。 根據本實施形態例，與以往在底壁具有貫通孔的情形 相較，在同一旋轉數下，可將脫水率（=乾衣衣類重量/ 脫水後衣類重量XI 00%)改善0.5〜1.0%，可將乾衣運轉時的 耗電量降低數l〇Wh左右。（綿與化纖的比例爲60%，40% 左右之衣類的情形下）。 第8圖係洗衣兼脫水槽3之底壁3f的凸狀肋部的另 一形態例。圖中的箭頭係顯示洗衣兼脫水槽3之脫水旋轉 時的旋轉方向。本實施形態例的特徵爲：凸狀肋部21對 ❹ 旋轉方向而言係呈平躺之狀態。藉由如此，可提昇凸狀肋 部21做爲風扇的性能，增加風量，所以可進一步促進衣 類溫度的上昇與衣類表面水份的蒸發，更加提昇脫水性能 〇 在底壁3f不設有貫通孔的話，也能具有降低脫水噪 音的效果。而在底壁3f設有貫通孔時，如第12圖（b)所示 般，在脫水旋轉時，會因爲通過貫通孔的空氣而使得在洗 衣兼脫水槽3之底壁部的氣流變得複雜且混亂。並且，會 -17- 201014940 在洗衣兼脫水槽3之外周面與外槽2之內周面之間的狹窄 空隙，產生向前流動的氣流D。因此，會產生風切聲。針 對此，在本實施形態例中，即如第7圖（b)所示般，以洗衣 兼脫水槽3內的循環流爲主，就不易產生亂流，風切聲就 會變小，脫水時的噪音就會減低。 再者，雖在以上說明中已針對底壁3f完全不設有貫 通孔的情形加以說明，但若至少在比底壁3 f之半徑的一 半更爲外側的部份不設有貫通孔的話，因爲凸狀肋部之風 扇作用而朝底壁3f之外緣部流動的空氣就不會通過貫通 ® 孔，朝外槽流出，所以空氣會沿著衣類的表面流動，而可 發揮如上述說明相同的效果。 第9圖係洗衣暨乾衣機之控制裝置38的方塊圖。50 爲微電腦，與連接於各開關12，13，13a的操作按鍵輸入 電路51、或水位感測器34、溫度感測器52相連，接收使 用者的按鍵操作或洗衣步驟、乾衣步驟時的各種資訊訊號 。來自微電腦50的輸出係連接於驅動電路54，並與供水 電磁閥16、排水閥25、馬達4、送風扇28、加熱器31等 ~

When the lotion is loaded, the detergent tray 7 is pulled out as indicated by the dotted line at the two points in Fig. 1. The lotion container 19 ® is fixed to the upper reinforcing material of the casing 1 . On the rear side of the lotion container 19, water supply solenoid valves 16, a bath water supply pump 17, and a water level sensor (not shown) and the like are provided. The lotion container 19 is connected to the outer tub 2. The water supply solenoid valve 16 is a multi-connect valve, 16 6b is a main water supply solenoid valve, and the washing water is supplied to the outer tank 2 through the lotion container 19. The 16c is a softener water supply solenoid valve, and is passed through the lotion container 19 toward the outer tank. Water supply. 16d is a cooling water solenoid valve that supplies water to a water-cooled dehumidifier (not shown). ® On the top cover, there is a water supply pipe connection port 16a from the faucet, and a suction pipe connection port 17a for bathing the remaining water. Reference numeral 29 denotes a drying duct which is provided on the inner side of the back surface of the casing 1 in the longitudinal direction, and the lower portion of the duct is connected to the air inlet 2a provided below the back surface of the outer tank 2 by a telescopic tube B29a made of rubber. A water-cooling dehumidifying mechanism (not shown) is incorporated in the drying duct 29, and the cooling water is supplied from the water supply solenoid valve 16 to the water-cooling and dehumidifying mechanism. The cooling water flows down through the wall surface of the drying duct 29, and -12-201014940 enters the outer tank 2 from the suction port 2a, and is discharged from the drain port 2b. The upper portion of the dryer duct 29 is in contact with a filter duct 27 provided on the upper right side of the casing 1 in the front-rear direction. The front mask of the filter catheter 27 has an opening into which the pull-out drying filter 8 is inserted. The air entering the filter duct 27 from the drying duct 29 flows into the mesh filter 8a of the clothes filter 8, and the cotton dust is removed. Cleaning the Drying Filter 8 The drying filter 8 can be pulled out and the mesh filter 8a can be taken out. Further, an opening portion is provided in the lower surface of the filter portion of the filter duct 27 of the filter duct 27, and the opening portion is connected to the air suction duct 33, and the other end of the air suction duct 33 is connected to the air inlet of the blower fan 28. . The blower fan 28 is composed of a drive motor 28a, a fan impeller (not shown), and a fan case 28b. The heater 31 is housed in the fan case 28b to heat the air from the fan impeller. The discharge port of the blower fan 28 is connected to the hot air duct 30. The hot air duct 30 is connected to the hot air outlet 32 provided in the outer tank cover 2d via a rubber-made extension tube A30a and a bellows joint 30b. In the present embodiment, the blower fan 28 is disposed on the upper right side of the casing 1_, so that the hot air blowing port 32 is provided at a position obliquely upward rightward of the outer tank cover 2d so that the distance from the hot air blowing port 32 is The shortest weir is provided with a temperature sensor (not shown) at the drain port 2b, the intake port of the blower fan 28, and the discharge port. The flow of wind during the operation of the dryer is as follows. Once the blower fan 28 is operated, the heater 31 is energized, and high-speed hot air is blown from the nozzle 3 2d into the washing and dewatering tank 3 (arrow 41), and the wet clothes are blown, and the clothes are added to the -13·201014940 clothes. The temperature causes the water to evaporate from the clothes. The air that has become high-temperature and high-humidity flows from the through-hole provided in the washing and dewatering tank 3 toward the outer tub 2, is sucked into the drying duct 29 from the intake port 2a, and flows from the bottom to the top in the drying duct 29 (arrow 42) . The cooling water from the water-cooling dehumidifying mechanism flows down the wall surface of the drying duct 29, because the hot and humid air is cooled and dehumidified by contact with the cooling water to become dry low-temperature air, and then enters the filtering duct 27 (arrow 43). The cotton dust is removed by the mesh filter 8a provided in the filter duct 27, enters the intake duct 33, and is sucked into the blower fan 28 (arrow 44). Then, it is heated again by the heater 31, and is blown into the washing and dewatering tank 3 to follow the loop. In this process, the washing and dewatering tank 3 is rotated in the forward and reverse directions at a low speed to push the clothes up to the vicinity of the nozzle 32d, so that high-speed hot air can be directly blown to the clothes. Fig. 7 is used to illustrate the flow of wind during hot air dehydration. Fig. 7(a) shows a state in which the blower fan 28 is operated, the heater 31 is energized, and hot air is blown from the nozzle 32d into the washing and dewatering tank 3. Fig. 7(b) shows that the blower fan 28 is stopped. The situation. Furthermore, the flow of wind is shown by the arrows in the figure. Actually, since the washing and dewatering tank 3 is rotating at a high speed, the air in the direction of rotation of the laundry/dewatering tank 3 flows, but the flow is omitted here for the sake of explanation. Further, in the dehydration, the clothes are attached to the washing and dewatering tank 3 by the centrifugal force, and the peripheral wall 3e' is in the form of a doughnut. Therefore, the through hole 3d in the outer peripheral wall 3e is blocked by the clothes, so that the air that passes through the inside from the inside of the washing and dewatering tank 3 hardly flows through the through hole 3d. First, the case where the blower fan 28 is operated will be described. A -14- 201014940 Once the washing and dewatering tank 3 is rotated, the convex rib formed on the bottom wall 3f becomes a centrifugal fan. The hot air (arrow 41) ejected from the nozzle is sucked from the center of the bottom wall 3f, flows toward the outer edge side of the bottom wall 3f (arrow 45), and then blows against the clothing attached to the outer peripheral wall 3e to make the flow direction It is slightly curved at 90 degrees, flows along the surface of the clothes, and flows toward the opening 3a of the washing and dewatering tank 3 while raising the temperature of the clothes. The air that has reached the front side of the washing and dewatering tank 3 flows from the gap between the outer tank cover 2d and the fluid balancer 3c toward the gap between the washing and dewatering tank 3 and the outer tank 2, and is sucked from the suction port 2a to the drying duct 29 (arrow 46). It is then sucked through the filter conduit 27 (arrow 43) through the suction duct 33 to the blower fan 28 (arrow 44). Further, a portion of the air that has reached the front side of the laundry and dewatering tank 3 is returned to the center of the bottom wall 3f by re-inhalation (arrow 47). Next, the case where the blower fan 28 is stopped will be described. In this case, once the washing and dewatering tank 3 is rotated, the air is sucked from the center portion of the bottom wall 3f of the washing and dewatering tank 3, and flows toward the outer edge side due to the centrifugal fan of the convex rib portion 11. . Then, as in the above, the clothes attached to the outer peripheral wall 3 e are changed in the flow direction, and flow along the surface of the clothes toward the opening 3a of the washing and dewatering tank 3. The air that has reached the front side of the washing and dewatering tank 3 is circulated along the door 9 toward the center of the washing and discharging tank 3, and is sucked to the center of the bottom wall 3f (arrow 48). As a result, since the hot air can surely flow on the surface of the clothes, the temperature of the clothes can be effectively increased. Further, it can promote the evaporation of moisture in clothing. Therefore, it is not necessary to increase the number of dehydration revolutions, that is, it does not increase the power consumption. -15- 201014940 can reduce the water content of clothing. Further, since the bottom wall 3f of the washing and dewatering tank 3 does not have a through hole, the following effects are obtained. The washing method of the drum type washing and drying machine is to rotate the laundry and dewatering tank 3 at a low speed, and the clothes in the washing and dewatering tank 3 are pushed up by the lifting rod 3b to perform washing. In order to push the wet clothes up, the motor 4 that drives the washing and dewatering tank 3 must have low speed and high torque characteristics. When the dehydration operation is maintained while maintaining such characteristics, the torque is relatively low compared to the case of laundry, but the torque is significantly insufficient in order to rotate at a high speed. Although the driving voltage of the motor 4 can be increased, a large amount of current flows to control the torque increase, but since the motor efficiency is lowered, the motor 4 generates heat. In general, a cooling fan can be used to cool the heat. In the present invention, the heat generation of the motor can be effectively utilized for dehydration. A portion of the heat generated by the motor 4 is conducted to the bottom wall 3f of the washing and dewatering tank 3 through the rotating shaft 4a of the motor 4. At this time, since the bottom wall 3f has no through hole, the heat conduction area of the bottom wall 3f is large (the heat resistance is small), so heat from the motor can be easily conducted to the outer peripheral wall 3e of the washing and dewatering tank 3, so that the outer peripheral wall 3e The temperature rises. Therefore, the temperature of the clothing that comes into contact with the outer wall 3e will also rise. Dehydration is the operation of removing moisture from clothing by the centrifugal force generated by high-speed rotation. In the dehydration, the clothing is attached to the outer peripheral wall 3e of the laundry and dewatering tank 3, and the moisture contained in the clothing flows from the inner side of the clothing toward the outer peripheral wall 3e side, and from the through hole 3d provided in the outer peripheral wall 3e toward the outer groove 2 Discharged inside. There are fine voids in the fibers of the garment or between the fibers because the capillary action of the water entering the portion keeps the moisture in the garment. Once de--16-201014940 water is removed, the capillary action is balanced with the centrifugal force and no further removal of water is possible. Therefore, the closer to the outer peripheral wall 3e of the washing and dewatering tank 3, the more the water content of the clothing part is. Although the capillary action is proportional to the interfacial tension of water, once the water temperature rises, the interfacial tension decreases. Therefore, as long as the temperature of the clothes is raised, the water content can be reduced. As described above, the present invention can effectively conduct heat generation of the motor to the outer peripheral wall 3e of the washing and dewatering tank 3, so that the water content of the clothes in the vicinity of the peripheral wall 3e can be effectively reduced. According to the present embodiment, the dehydration rate (=dry clothing type weight/dehydrated clothing weight XI 00%) can be improved by 0.5 to 1.0% at the same number of rotations as compared with the case where the bottom wall has a through hole. The power consumption during the operation of the clothes dryer can be reduced by a few l〇Wh. (In the case of cotton and chemical fiber ratio of 60%, about 40% of clothing). Fig. 8 is a view showing another example of the convex rib of the bottom wall 3f of the washing and dewatering tank 3. The arrow in the figure shows the direction of rotation when the washing and dewatering tank 3 is rotated by dehydration. The feature of this embodiment is that the convex rib 21 is in a flat state in the direction of rotation of the crucible. In this way, the performance of the convex rib 21 as a fan can be improved, and the air volume can be increased, so that the temperature rise of the clothing and the evaporation of the moisture of the surface of the clothing can be further promoted, and the dehydration performance can be further improved. The through hole is not provided in the bottom wall 3f. In addition, it can also have the effect of reducing dehydration noise. When the through hole is provided in the bottom wall 3f, as shown in Fig. 12(b), the airflow in the bottom wall portion of the washing and dewatering tank 3 becomes due to the air passing through the through hole during the spin-drying rotation. Complex and confusing. Further, -17-201014940, a narrow gap between the outer peripheral surface of the laundry and dewatering tank 3 and the inner peripheral surface of the outer tub 2, generates a forward-flowing airflow D. Therefore, wind cuts are generated. In view of this, in the present embodiment, as shown in Fig. 7(b), the circulation flow in the washing and dewatering tank 3 is dominant, and turbulent flow is less likely to occur, and the wind cut sound becomes small and dehydrated. The noise will be reduced. Further, in the above description, the case where the through hole is not provided at all in the bottom wall 3f has been described. However, if at least the through hole is not provided in the portion outside the half of the radius of the bottom wall 3f, Since the air flowing toward the outer edge portion of the bottom wall 3f by the action of the fan of the convex rib does not flow through the through hole and flows out toward the outer groove, the air flows along the surface of the clothing, and the same as described above. Effect. Figure 9 is a block diagram of the control device 38 of the washer and dryer. 50 is a microcomputer connected to the operation key input circuit 51 connected to each of the switches 12, 13, 13a, or the water level sensor 34 and the temperature sensor 52, and receives the user's button operation or the washing step and the drying step. Various information signals. The output from the microcomputer 50 is connected to the drive circuit 54, and is connected to the water supply solenoid valve 16, the drain valve 25, the motor 4, the blower fan 28, the heater 31, etc., to control the switching, rotation, and energization. Further, it is connected to the seven-segment LED display 14, the light-emitting diode 56, and the buzzer 57 for informing the user of the operation state of the washing machine. Just press the power switch 39, connect the power supply to start the above microcomputer 50, and execute the basic control processing program for the laundry and drying clothes as shown in Fig. 10. -18- 201014940 Step S101 Perform the status check and initial setting of the washer and dryer. The display 16 of the operation panel 6 is turned on in step S102, and the laundry/drying stroke is set in accordance with the instruction from the operation button switch 13. In the state where no input is indicated, the standard laundry/drying stroke is automatically set, or the laundry/drying stroke according to the last execution. For example, when the operation button switch 13a is input, the efficient stroke of the clothes is set. Step S103 monitors the instruction input from the start switch 12 of the operation panel 6, and processes them separately. Although it is not described in the drawing, just press the start switch! 2 The volume sensing will be performed. The cloth amount sensing can, for example, rotate the washing and dewatering tank 3 at a low speed or accelerate it to a predetermined number of rotations, and measure the amount of cloth from the current 値 of the motor 4 at that time. Then, the display 14k shows the time until the drying is completed. Step S 1 0 4 Perform laundry. The washing is carried out in the order of washing, intermediate dewatering, washing, and finally dewatering, and the same as the general drum type washing and drying machine, the detailed description thereof will be omitted. Step S 1 0 5 -19· 201014940 Check if the laundry drying stroke has been set and handle it separately. The operation is completed only when the laundry schedule is set. Step S106 When the laundry drying stroke is set, hot air dehydration is performed. The hot air dehydration causes the blower fan 28 to rotate at a low speed, energizes the heater 31, and blows hot air into the washing and dewatering tank 3 to increase the temperature of the clothes. At the same time, the washing and dewatering tank 3 is rotated at a high speed to effectively remove moisture from the warm clothing. In the present embodiment, in the case of spin-drying, the amount of air flowing on the surface of the clothes is large, and the outer wall surface 3e of the washing and dewatering tank 3 is heated by the heat generated by the motor 4, and the temperature of the clothes is increased. The step of hot air dehydration eliminates the need to energize the heater 31, thereby reducing power consumption. Step S107 performs a drying operation. The blower fan 28 and the heater 31 are operated, and the washing and dewatering tank 3 is repeatedly rotated in the forward and reverse directions, and the hot and cold air is blown toward the clothes while changing the position of the laundry and dewatering tank 3 and the underwear. When the temperature of the whole garment is increased, the water can be evaporated from the clothes. In step S108, it is judged whether or not the drying clothes are completed by using the temperature of the hot air or the drainage temperature of the cooling water. -20- 201014940 Step SI 09 Perform cooling operation. The forward and reverse rotation of the washing and dewatering tank 3 is maintained, and the blower fan 28 is kept in operation, and the energization of the heater 31 is terminated to supply air. The air supply is carried out until a predetermined time, or the circulating air is lowered below the pre-temperature to cool the clothes and complete the drying operation. As described above, according to the present embodiment, a washing and drying machine includes: a rotating drum for housing clothes, a rotating drum, a rotating drum disposed on the same core, and an outer tank for storing the washing water, and driving the rotating drum. a motor, a casing supporting the rotating drum, and a blowing means for supplying hot air to the rotating drum to perform a drying operation, wherein the rotating drum is connected to the motor The bottom surface of the rotating drum of the rotating shaft has a plurality of convex ribs radially extending from the center, and the outer peripheral portion of the bottom wall surface is configured to block ventilation (or the ventilation is not provided on the bottom wall surface of the rotating drum) Through hole). Further, the convex rib is configured to have a twist angle with respect to the rotation direction of the rotary drum. Further, a washing and drying machine includes: a rotating drum for accommodating clothes, a rotating drum, a rotating drum disposed on the same core, an outer tank for storing the washing water, a motor for driving the rotating drum, and supporting the above a washing and drying machine for rotating the drum and a blowing means for supplying hot air to the rotating drum to perform a drying operation, wherein the rotating drum is connected to the rotating drum bottom of the motor rotating shaft The wall surface has a plurality of convex ribs extending radially from the center, and a through hole for the ventilation - 21 · 201014940 is not provided in at least a half of the radius of the bottom wall surface. In the hot air dehydration step of heating the clothes while the spinner rotates at a high speed while rotating at a high speed, the air generated by the fan of the rotation of the convex rib does not move toward the air in the initial stage of the dry clothes. The outer tank flows out, and a large amount of flow is attached to the surface of the garment of the rotating drum by the centrifugal force, so that the temperature of the garment can be effectively increased and the evaporation of water on the surface of the garment can be promoted without increasing the dehydration step. The power consumption of the time, while reducing the water content of the clothing. Therefore, the power consumption of the drying operation can be reduced to achieve energy saving.
