FIG. 5 is a diagram showing a state of the washing object when the amount of the washing object stored in the washing and dewatering tank is large, for example, a schematic diagram showing the state of the washing object after washing. FIG. 6 is a schematic diagram showing a state when the washing object climbs up the tank cover during dehydration. FIG. 7 is a schematic diagram showing how a washing object comes into contact with parts of a washing machine. FIG. 8 is a schematic diagram showing a state in which the climbed washing object is dropped into the washing and dewatering tank. FIG. 9 is a schematic diagram showing a state after a washing object is dropped into a washing and dewatering tank.
例如，在清洗兼脫水槽2內放入很多(多量)的清洗物W的情況時，結束清洗過程和清水清洗過程之後，如第5圖所示，清洗物W是具有呈山型***的形態。如此從清洗物W***的狀態使洗衣機1的運轉過程進入脫水過程的話，藉由由清洗兼脫水槽2的旋轉所產生的離心力，如第6圖所示，會使清洗物W貼附在清洗兼脫水槽2的胴板31側，並且使清洗物W的一部分從清洗兼脫水槽2浮起而爬上槽蓋18。藉由此狀態直接高速脫水，如第7圖所示，清洗物(例如輕的素材的白襯衫的袖)W，會從上面蓋9的內側的槽蓋18與內側中的洗衣機1內的零件接觸，使衣物破損。For example, when a large amount (a large amount) of washings W are placed in the washing and dewatering tank 2, after the washing process and the washing process with fresh water are finished, as shown in FIG. 5, the washings W have a mountain-shaped bulge. . When the operation process of the washing machine 1 enters the dehydration process from the state where the washing object W is raised in this way, the centrifugal force generated by the rotation of the washing and dewatering tank 2 causes the washing object W to adhere to the washing as shown in FIG. The faucet 31 side of the cum-dehydration tank 2 floats a part of the laundry W from the cum-dehydration tank 2 and climbs onto the tank cover 18. In this state, high-speed dewatering is performed directly. As shown in FIG. 7, the laundry (for example, the sleeves of a white shirt of light material) W will be covered from the upper slot cover 18 on the inner side of the cover 9 and the parts in the washing machine 1 Contact may damage clothing.
在此，在本實施例中，在第6圖的狀態，進行旋轉給水。具體而言，如第8圖所示因為衣物(清洗物W)是碰到給水盒26，所以將清洗兼脫水槽2由低速旋轉，且從給水盒26，對於爬上槽蓋18的清洗物W的一部分加水。又，來自給水盒26的給水，是與在通常的清洗過程等朝清洗兼脫水槽2內給水的情況同樣地進行。因此，進行旋轉給水用的流路不需要重新設置。Here, in this embodiment, the rotary water supply is performed in the state of FIG. 6. Specifically, as shown in FIG. 8, since the laundry (the washing object W) touches the water supply tank 26, the washing and dewatering tank 2 is rotated at a low speed, and the washing product climbing from the water supply tank 26 to the tank cover 18 Add a part of W. The water supply from the water supply tank 26 is performed in the same manner as in the case where water is supplied into the washing and dewatering tank 2 in a normal washing process or the like. Therefore, it is not necessary to reset the flow path for the rotary feed water.
沾了水的清洗物W是包含水而變重，爬上槽蓋18的上面的清洗物W，是由該水的重量而朝清洗兼脫水槽2中推回。如此，即使清洗物W是從清洗兼脫水槽2爬上槽蓋18的情況，藉由對於爬上的清洗物W加水，如第9圖所示，就可使清洗物W朝清洗兼脫水槽2落入(例如，直到與平衡環23的內周壁23a相面對的位置為止)，可以抑制清洗物W的破損。The water-soaked washing material W is heavy and contains water. The washing material W climbing up the upper surface of the tank cover 18 is pushed back into the washing and dewatering tank 2 by the weight of the water. In this way, even if the washing object W climbs from the washing and dewatering tank 2 to the tank cover 18, by adding water to the climbing washing object W, as shown in FIG. 9, the washing object W can be directed toward the washing and dewatering tank. 2 falls (for example, up to the position facing the inner peripheral wall 23a of the balance ring 23), and the damage of the washing | cleaning object W can be suppressed.
第10圖，是顯示洗衣機的自動運轉動作的流程圖，第11圖，是顯示給水的時間點的圖表。如第10圖所示，控制單元19，是電源按鈕203被按壓使電源被投入的話就起動，對應被選擇的程序，實行第10圖所示的清洗的基本的控制處理程式。Fig. 10 is a flowchart showing the automatic operation of the washing machine, and Fig. 11 is a graph showing the time point of water supply. As shown in FIG. 10, the control unit 19 is a basic control processing program for cleaning shown in FIG. 10 in accordance with the selected program and is activated when the power button 203 is pressed to turn on the power.
在步驟S301中，控制單元19，是實行洗衣機1的狀態確認及初期設定。又，在初期設定中，在進行了控制處理系的初期化處理之後，進行離合器機構6b的初期化控制處理。In step S301, the control unit 19 performs state confirmation and initial setting of the washing machine 1. In the initial setting, after the initialization processing of the control processing system is performed, the initialization control processing of the clutch mechanism 6b is performed.
在步驟S302中，控制單元19，是依據來自清洗程序按鈕205(第4圖參照)的輸入指示設定清洗程序。在無輸入指示的狀態下，自動地設定成標準的清洗程序或是前次實施的清洗程序。In step S302, the control unit 19 sets a cleaning program in accordance with an input instruction from the cleaning program button 205 (refer to FIG. 4). When there is no input instruction, it is automatically set to the standard cleaning program or the previous cleaning program.
在步驟S303中，控制單元19，是監視來自開始按鈕204的開始按鈕訊號的輸入。控制單元19，若判別為無開始按鈕訊號的輸入的情況時，反覆步驟S303的處理，若判別為有開始按鈕訊號的輸入的情況時，朝步驟S304前進。In step S303, the control unit 19 monitors the input of the start button signal from the start button 204. If the control unit 19 determines that there is no start button signal input, it repeats the processing of step S303, and if it determines that there is a start button signal input, it proceeds to step S304.
在步驟S304中，控制單元19，是實行洗劑量檢出處理。此洗劑量檢出處理，是在將清洗水給水之前的清洗物是在乾布的狀態，且將清洗兼脫水槽2靜止的狀態下，將攪拌翼3朝一方向旋轉時，藉由依據作用於該攪拌翼3的旋轉負荷量將清洗物W的布量檢出(布量檢測)。控制單元19，是依據檢出的布量求得洗劑的適量(洗劑量)。洗劑量，是藉由參照預先設定的布量及洗劑量的對照表格而求得。控制單元19，是將求得的洗劑量，顯示於顯示部201(第4圖參照)。判別為對應此洗劑量的布量(負荷)是例如額定的8成以上的情況，朝過程A前進，判別為布量(負荷)是未滿額定的8成的情況，朝過程B前進。如此，在第1實施例中，可以對應布量(負荷)，如過程A及過程B，將脫水方法變更。In step S304, the control unit 19 executes a lotion detection process. This washing amount detection process is performed when the stirring blade 3 is rotated in one direction when the washing object before the washing water is supplied with water is in a dry cloth state, and the washing and dewatering tank 2 is stationary. The rotation load of the stirring blade 3 detects the cloth amount of the washing object W (cloth amount detection). The control unit 19 obtains an appropriate amount (lotion amount) of the lotion based on the detected cloth amount. The washing amount is obtained by referring to a comparison table of a predetermined cloth amount and a washing amount. The control unit 19 displays the obtained washing amount on the display unit 201 (refer to FIG. 4). When it is determined that the cloth amount (load) corresponding to the washing amount is 80% or more of the rated value, the process proceeds to process A. When the cloth amount (load) is less than 80% of the rated value, the process proceeds to process B. In this way, in the first embodiment, the dewatering method can be changed in accordance with the amount (load) of the cloth, such as the process A and the process B.
在步驟S305中，控制單元19，是在清洗的設定水位中，將離合器機構6b設定成攪拌模式，在將清洗兼脫水槽2固定的狀態下將攪拌翼3旋轉地實行清洗。且，控制單元19，是實行將攪拌翼3正逆旋轉的約1分鐘的均一化攪拌。In step S305, the control unit 19 sets the clutch mechanism 6b to the stirring mode at the washing set water level, and performs the washing by rotating the stirring blade 3 while the washing and dewatering tank 2 is fixed. In addition, the control unit 19 performs uniform stirring by rotating the stirring blade 3 forward and reverse for about one minute.
其後，朝步驟S306前進，控制單元19，是實行清水清洗過程。控制單元19，首先是將排水閥13(第1圖參照)打開，將清洗兼脫水槽2及外槽7內的清洗水排水。由此，通過排水軟管11朝機外使清洗後的清洗水被排出。在清洗運轉中，在清洗兼脫水槽2內將很多的清洗物W放入的情況時，結束清洗過程之後，清洗物W是具有呈山型***的形態(第5圖參照)。Thereafter, the process proceeds to step S306, and the control unit 19 executes a clean water washing process. The control unit 19 first opens the drain valve 13 (refer to FIG. 1) to drain the washing water in the washing / dehydrating tank 2 and the outer tank 7. Thereby, the washing water after washing | cleaning is discharged | emitted outside the machine through the drain hose 11. In the case where a large number of articles to be washed W are placed in the washing and dewatering tank 2 during the washing operation, after the washing process is completed, the articles to be washed W have a mountain-shaped hump (see FIG. 5).
且控制單元19，是將清洗水排水後，實行預脫水。在此預脫水中，洗劑成分殘留很多的清洗水是朝清洗兼脫水槽2外被甩開，透過排水閥13朝機外被排出。即，在預脫水中，是使清洗兼脫水槽2內的衣物(清洗物W)會貼附在清洗兼脫水槽2的內壁面的程度為止旋轉。In addition, the control unit 19 performs pre-dehydration after draining the washing water. In this pre-dehydration, the washing water with a lot of lotion components remaining is thrown away from the washing and dewatering tank 2 and discharged to the outside through the drain valve 13. That is, in the pre-dehydration, the laundry (the washing object W) in the washing and dewatering tank 2 is rotated to such an extent that the laundry (the washing object W) adheres to the inner wall surface of the washing and dewatering tank 2.
且控制單元19，是清洗兼脫水槽2的旋轉速度是從0(零)到達規定的第1旋轉速度(例如400rpm)之後，將清洗兼脫水槽2的旋轉速度直到慢到比第1旋轉速度低的規定的第2旋轉速度(例如20rpm)為止實行旋轉給水1(第1次的旋轉給水)。藉由進行此旋轉給水1而朝從清洗兼脫水槽2爬上槽蓋18的清洗物的一部分加水(第8圖參照)。此時，包含水的清洗物W的一部分是藉由水的重量而再度朝清洗兼脫水槽2內返回(第9圖參照)。藉由進行這種旋轉給水1，使從清洗兼脫水槽2的上端的衣物(清洗物W)的躥出被消解。又，進行旋轉給水1的時間，是藉由事前的試驗而被適宜決定者。In addition, the control unit 19 rotates the washing and dewatering tank 2 until the rotation speed of the washing and dewatering tank 2 reaches a predetermined first rotation speed (for example, 400 rpm) from 0 (zero) to a speed lower than the first rotation speed. The rotary feed water 1 (the first rotary feed water) is performed up to a low predetermined second rotary speed (for example, 20 rpm). By performing this rotary feed water 1, water is added to a part of the washing | cleaning material which climbed up from the washing and dewatering tank 2 to the tank cover 18 (refer FIG. 8). At this time, a part of the washing | cleaning material W containing water is returned to the washing and dewatering tank 2 again by the weight of water (refer FIG. 9). By performing such a rotation of the feed water 1, the scooping out of the laundry (the laundry W) from the upper end of the washing and dewatering tank 2 is eliminated. In addition, the time for which the rotary feed water 1 is performed is determined appropriately by a prior test.
又，在旋轉給水1中藉由一邊使清洗兼脫水槽2旋轉一邊朝清洗物W被給水，就可以朝槽蓋18的圓周方向的整體加水。因此，即使清洗物W是由複數處爬上槽蓋18的情況，也可以將爬上的複數處的清洗物W返回至清洗兼脫水槽2內。且，藉由在旋轉給水時使清洗兼脫水槽2由比第1旋轉速度更低的旋轉速度(第2旋轉速度，水即使接觸衣物也不會飛散程度的旋轉速度)旋轉，就可以將水有效率地滲透清洗物W。Furthermore, in the rotary feed water 1, water is supplied to the washing object W while the washing and dewatering tank 2 is rotated, so that water can be added to the entire circumferential direction of the tank cover 18. Therefore, even when the washing object W climbs up to the tank cover 18 from a plurality of places, the washing object W that climbs up a plurality of places can be returned to the washing and dewatering tank 2. In addition, when the washing and dewatering tank 2 is rotated at a lower rotation speed than the first rotation speed (the second rotation speed, the rotation speed at which the water does not scatter even if it comes in contact with the clothes) when the feed water is rotated, the water can be removed. Efficiently penetrate the washing W.
且控制單元19，是藉由旋轉給水1而將清洗物W朝清洗兼脫水槽2內落入之後(第9圖參照)，實行脫水(在預脫水之後被實行的脫水)。在此脫水中，將清洗兼脫水槽2上昇至比第1旋轉速度(例如400rpm)更高的第3旋轉速度(例如700rpm)為止。即使從此狀態進行了脫水，因為是從清洗物W已移動的狀態(貼附在清洗兼脫水槽2的內壁面的狀態)開始脫水，所以清洗物W不會大移動。因此，清洗物W不會再度爬上槽蓋18。In addition, the control unit 19 executes dehydration (dehydration performed after preliminary dehydration) after dropping the washing object W into the washing and dewatering tank 2 by rotating the feed water 1 (refer to FIG. 9). In this dehydration, the washing and dewatering tank 2 is raised to a third rotation speed (for example, 700 rpm) higher than the first rotation speed (for example, 400 rpm). Even if dehydration is performed from this state, since the washing object W has moved (a state attached to the inner wall surface of the washing and dewatering tank 2), the washing object W does not move much. Therefore, the cleaning object W does not climb on the tank cover 18 again.
且控制單元19，是脫水後，實行旋轉給水2。在此的旋轉給水2，是與旋轉給水1相異，將排水閥13關閉，電磁給水閥16被打開，朝清洗兼脫水槽2旋轉給水。由此，清水清洗水是被滯留在清洗兼脫水槽2。The control unit 19 executes the rotary water supply 2 after dehydration. The rotary water supply 2 here is different from the rotary water supply 1, and the drain valve 13 is closed, and the electromagnetic water supply valve 16 is opened to rotate the water supply toward the washing and dewatering tank 2. As a result, the clean water washing water is retained in the washing and dewatering tank 2.
且控制單元19，是將離合器機構6b由攪拌模式將攪拌翼3正逆旋轉使實行將清洗物W攪拌用的清水清洗。此時，控制單元19，是將後處理劑給水電磁閥(未圖示)開閥，朝洗劑和後處理劑投入裝置(未圖示)給水，將被投入洗劑和後處理劑投入裝置的後處理劑室的後處理劑與水一起朝清洗兼脫水槽2內投入。且，控制單元19，是滯留清水清洗實行規定時間之後，終了滯留清水清洗運轉。In addition, the control unit 19 rotates the clutch mechanism 6b in the forward and reverse directions of the stirring blade 3 in the stirring mode to perform washing by stirring the washing object W with clean water. At this time, the control unit 19 opens the post-treatment agent feed water solenoid valve (not shown), feeds water to the lotion and post-treatment agent input device (not shown), and inputs the lotion and post-treatment agent input device. The post-treatment agent in the post-treatment agent chamber of the upper part is charged into the cleaning and dewatering tank 2 together with water. In addition, the control unit 19 ends the stagnant water washing operation after the stagnant water washing operation is performed for a predetermined time.
其後，在步驟S307中，控制單元19，是實行脫水過程。在此脫水過程中，將排水閥13打開，將外槽7內的清水清洗水(清洗水)排水。在此排水中，為了使脫水時的起動穩定，也有在某一定量的清水清洗水殘留的狀態下移動至最終脫水的情況。Thereafter, in step S307, the control unit 19 executes a dehydration process. In this dehydration process, the drain valve 13 is opened, and the clean water (washing water) in the outer tank 7 is drained. In this drainage, in order to stabilize the startup at the time of dehydration, it may be moved to the final dehydration in a state where a certain amount of clean water washing water remains.
且控制單元19，是將離合器機構6b朝脫水模式切換，朝馬達6a通電，實行最終脫水。此時，將清洗兼脫水槽2由高速(例如700rpm)旋轉使被包含於清洗物的水被脫水。規定時間經過後，將清洗兼脫水槽2的旋轉停止，終了脫水運轉。In addition, the control unit 19 switches the clutch mechanism 6b to the dehydration mode, energizes the motor 6a, and performs final dehydration. At this time, the washing and dewatering tank 2 is rotated at a high speed (for example, 700 rpm) to dehydrate the water contained in the washing object. After the predetermined time has elapsed, the rotation of the washing and dewatering tank 2 is stopped, and the dehydration operation is terminated.
另一方面，在步驟S304中，控制單元19，是判別為負荷是未滿額定的8成的情況時，朝過程B前進。又，過程B的步驟S308、S310，因為是與過程A的步驟S305、S307同樣，所以只有說明步驟S309。On the other hand, in step S304, when the control unit 19 determines that the load is less than 80% of the rated value, it proceeds to process B. Since steps S308 and S310 of the process B are the same as steps S305 and S307 of the process A, only step S309 will be described.
在步驟S309中，控制單元19，是實行清水清洗過程。在此清水清洗過程中，控制單元19，是將排水閥13(第1圖參照)打開，將清洗過程(S308)中的包含很多洗劑成分的清洗水排水。且，將離合器機構6b朝脫水模式切換，進行脫水。又，此脫水時的清洗兼脫水槽2的旋轉速度，是設定成例如700rpm。In step S309, the control unit 19 executes a clean water washing process. In this clean water washing process, the control unit 19 opens the drain valve 13 (refer to FIG. 1), and drains the washing water containing a lot of detergent components in the washing process (S308). Then, the clutch mechanism 6b is switched to a dehydration mode to perform dehydration. The rotation speed of the washing and dewatering tank 2 during the dehydration is set to, for example, 700 rpm.
且排水閥13被關閉，電磁給水閥16被打開，朝清洗兼脫水槽2及外槽7內進行給水。在此的給水，是與前述的步驟S306中的旋轉給水2同樣地進行。且，一邊將離合器機構6b朝攪拌模式切換，一邊將攪拌翼3朝正逆雙方向旋轉，進行規定時間的清水清洗(滯留清水清洗)。In addition, the drain valve 13 is closed, and the electromagnetic water supply valve 16 is opened, and water is supplied into the washing and dewatering tank 2 and the outer tank 7. The water supply here is performed in the same manner as the rotary water supply 2 in step S306 described above. Then, while the clutch mechanism 6b is switched to the stirring mode, the stirring blade 3 is rotated in both forward and reverse directions to perform clean water cleaning (stagnant clean water cleaning) for a predetermined time.
如第11圖所示，在第1實施例中，在清水清洗過程，進行預脫水的情況時，將旋轉速度從0直到400rpm(第1旋轉速度)為止上昇之後，實行將旋轉速度一旦下降的處理。又，比第1旋轉速度更低的第2旋轉速度(例如20rpm)，是可以抑制朝清洗物W給水時的水的飛散，且，可以朝旋轉給水後的脫水處理圓滑地移動的旋轉速度較佳。As shown in FIG. 11, in the first embodiment, in the case of pre-dehydration in the fresh water washing process, the rotation speed is increased from 0 to 400 rpm (the first rotation speed), and then the rotation speed is once reduced. deal with. In addition, the second rotation speed (for example, 20 rpm), which is lower than the first rotation speed, can suppress the scattering of water when the water is supplied to the washing object W, and the rotation speed can be smoothly moved toward the dehydration treatment after the rotating water supply. good.
預脫水後的旋轉給水(旋轉給水1)，是進行規定時間。又，規定時間，是設定成可以將爬上槽蓋18的清洗物W朝清洗兼脫水槽2內落入的時間，藉由事前的試驗而被決定。The pre-dehydration rotary water supply (rotary water supply 1) is performed for a predetermined time. In addition, the predetermined time is a time set so that the washing object W climbing up the tank cover 18 can be dropped into the washing and dewatering tank 2 and is determined by a previous test.
旋轉給水後的脫水，是由比預脫水時的旋轉速度(第1旋轉速度)更高的旋轉速度(第3旋轉速度)進行。藉由旋轉給水的處理，而使清洗物W朝清洗兼脫水槽2內落入，因為清洗物W不會再度爬上槽蓋18，所以可以將脫水時的旋轉速度設定成比預脫水時更高。The dehydration after the spin-feed is performed at a higher rotation speed (the third rotation speed) than the rotation speed (the first rotation speed) during the pre-dehydration. The rotating feed water treatment causes the washing object W to fall into the washing and dewatering tank 2. Since the washing object W does not climb up to the tank cover 18 again, the rotation speed during dehydration can be set higher than that during pre-dehydration. high.
如以上說明，第1實施例的洗衣機1，是具備：在內部將水滯留的外槽7、及可旋轉自如地被支撐於外槽7內且收容清洗物W的清洗兼脫水槽2、及設於清洗兼脫水槽2的底部的攪拌翼3。且，洗衣機1，是具備：將清洗兼脫水槽2旋轉驅動的驅動裝置6、及被安裝於清洗兼脫水槽2的上部的平衡環23、及被安裝於外槽7的上端部的槽蓋18。且，洗衣機1，是具備：朝外槽7及清洗兼脫水槽2供給水的電磁給水閥16及給水盒26、及將清洗兼脫水槽2及攪拌翼3及電磁給水閥16控制的控制單元(控制部)19。控制單元19，是在清水清洗過程中的預脫水後從給水盒26朝清洗物W給水(步驟S306的旋轉給水1參照)。由此，藉由對於爬上槽蓋18的清洗物W(清洗物W的一部分)加水，使沾了水的清洗物W因包含水而變重，由該水的重量朝清洗兼脫水槽2中使爬上槽蓋18的上面的清洗物W落下。因此，在清水清洗過程的預脫水中，可以抑制清洗物W進入清洗兼脫水槽2及外槽7之間的間隙S(第2圖參照)，可防止清洗物W的破損。且，因為可以抑制從清洗兼脫水槽2躥出的清洗物W躥出，躥出的清洗物W與洗衣機1內的零件接觸，所以可以抑制洗衣機1的故障。As described above, the washing machine 1 according to the first embodiment includes an outer tank 7 that retains water therein, and a washing and dewatering tank 2 that is rotatably supported in the outer tank 7 and that houses the washings W. 2 and A stirring blade 3 provided at the bottom of the washing and dewatering tank 2. Further, the washing machine 1 includes a drive device 6 for rotationally driving the washing and dewatering tank 2, a balance ring 23 attached to an upper portion of the washing and dewatering tank 2, and a groove cover attached to an upper end portion of the outer tank 7. 18. Furthermore, the washing machine 1 is provided with a control unit that controls the electromagnetic water supply valve 16 and the water supply box 26 that supply water to the outer tank 7 and the washing and dewatering tank 2 and controls the cleaning and dewatering tank 2 and the stirring wing 3 and the electromagnetic water supply valve 16. (Control section) 19. The control unit 19 supplies water from the water supply box 26 to the washing object W after the pre-dehydration in the clean water washing process (refer to the rotating water supply 1 in step S306). Accordingly, by adding water to the washing object W (a part of the washing object W) climbing on the tank cover 18, the washing substance W that has been wetted with water contains weight, and the weight of the water is applied to the washing and dewatering tank 2. The washing | cleaning material W which climbed up the upper surface of the tank cover 18 was dropped. Therefore, in the pre-dehydration in the clean water washing process, it is possible to prevent the washing object W from entering the gap S (refer to FIG. 2) between the washing and dewatering tank 2 and the outer tank 7, and to prevent the washing object W from being damaged. In addition, it is possible to suppress the washing out of the washing object W from the washing and dewatering tank 2 and contact the parts in the washing machine 1 with the washing object W, so that the failure of the washing machine 1 can be suppressed.
且在第1實施例中，控制單元19，是將清水清洗過程中的脫水分開複數次地實行，藉由在預脫水(其一的脫水)及脫水(其他的脫水)之間朝清洗物W給水來實行修正清洗物W朝槽蓋18爬上的控制。由此，因為可以藉由預脫水(其一的脫水)來抑制清洗物W再度爬上，所以成為可將脫水(其他的脫水)時的旋轉速度提高地脫水。Furthermore, in the first embodiment, the control unit 19 executes the dehydration in the clean water washing process several times and separates it from the pre-dehydration (one dehydration) and dehydration (other dehydration) toward the washing object W. Feed water is used to perform control to correct the washing object W to climb up to the tank cover 18. Accordingly, the pre-dehydration (one type of dehydration) can be used to prevent the washing object W from climbing up again, so that the spin speed during dehydration (other dehydration) can be increased to dehydrate.
且在第1實施例中，具備：將攪拌翼3朝一方向旋轉時，依據作用於攪拌翼3的旋轉負荷量檢出清洗物W的布量的布量檢出手段。控制單元19，是對應藉由布量檢出手段被檢出的布量將清水清洗過程中的脫水方法變更(第10圖的S304參照)。且，只有布量多的情況時，藉由實行行程A，讓使用水量和消耗電力減少。Further, in the first embodiment, when the stirring blade 3 is rotated in one direction, a cloth amount detection means is provided for detecting the cloth amount of the washing object W based on the rotation load amount acting on the stirring blade 3. The control unit 19 changes the dewatering method in the clean water washing process according to the amount of fabric detected by the fabric amount detection means (refer to S304 in FIG. 10). In addition, when there is only a large amount of cloth, the use of stroke A reduces the amount of water used and power consumption.
且在第1實施例中，控制單元19，是在脫水時若清洗兼脫水槽2到達規定的旋轉速度(第1旋轉速度)的情況，一旦降低旋轉速度(成為第2旋轉速度)朝清洗物給水之後，再度實行脫水。由此，藉由降低清洗兼脫水槽2的旋轉速度，使從給水盒26被給水的水成為容易朝清洗物W滲透，就可以將清洗物W朝清洗兼脫水槽2內有效地落入。Furthermore, in the first embodiment, the control unit 19 is a case where the cleaning and dewatering tank 2 reaches a predetermined rotation speed (first rotation speed) during dehydration, and once the rotation speed is reduced (becomes the second rotation speed) toward the washing object After the water supply, dehydration was carried out again. Accordingly, by reducing the rotation speed of the washing and dewatering tank 2, the water fed from the water supply tank 26 can easily penetrate into the washing object W, and the washing object W can be effectively dropped into the washing and dewatering tank 2.
且在第1實施例中，平衡環23，是具備從該平衡環23的內周壁23a(環狀內壁)朝上方伸出地形成的肋25，肋25的高度及槽蓋18的內周壁18a的高度是相同。由此，可以抑制清洗物W嚙入平衡環23及槽蓋18之間的間隙。且，藉由組合：設置肋25使該肋25的高度及槽蓋18的內周壁18a的高度成為相同的構成、及步驟S306的旋轉給水1，就可以將嚙入有效地抑制。Further, in the first embodiment, the balance ring 23 is provided with a rib 25 formed to protrude upward from the inner peripheral wall 23 a (annular inner wall) of the balance ring 23, the height of the rib 25 and the inner peripheral wall of the groove cover 18. The height of 18a is the same. As a result, it is possible to prevent the washing object W from entering the gap between the balance ring 23 and the groove cover 18. In addition, by combining the rib 25 with the same configuration as the height of the rib 25 and the inner peripheral wall 18a of the groove cover 18 and the rotation of the feed water 1 in step S306, the biting can be effectively suppressed.
如此，在第1實施例中，在清水清洗過程中，清洗物W爬上槽蓋18上之後，藉由進行旋轉給水1來修正清洗物W的爬上，藉由防止與洗衣機1內的各式各樣的零件的接觸，就可以實現可以抑制洗衣機1的故障或是清洗物W的破損的洗衣機1。In this way, in the first embodiment, after the washing object W climbs onto the tank cover 18 during the washing with fresh water, the climbing of the washing object W is corrected by rotating the feed water 1 to prevent the washing object W from climbing up with the washing object 1. The contact of various parts can realize the washing machine 1 which can suppress the failure of the washing machine 1 or the damage of the washing object W.
(第2實施例) 第12圖，是顯示第2實施例的洗衣機的行程動作的流程圖。又，對於與第10圖所示的流程圖同樣的控制，是附加相同的步驟符號，並省略重複的說明。且，在第2實施例中，省略第1實施例中的步驟S304(負荷判別)，時常進行步驟S306及S311的處理。(Second Embodiment) Fig. 12 is a flowchart showing a stroke operation of a washing machine according to a second embodiment. It should be noted that the same steps as those in the flowchart shown in FIG. 10 are assigned the same step numbers, and redundant descriptions are omitted. Furthermore, in the second embodiment, step S304 (load discrimination) in the first embodiment is omitted, and the processes of steps S306 and S311 are always performed.
如第12圖所示，在步驟S311中，控制單元19，是實行脫水過程。在此脫水過程中，將清水清洗過程(S306)中的清水清洗水，將排水閥13打開朝機外排出，在排出後實行預脫水。此預脫水，是與步驟S306的預脫水同樣，清洗兼脫水槽2的旋轉速度是到達第1旋轉速度(例如400rpm)之後，將清洗兼脫水槽2的旋轉速度減至比第1旋轉速度更低的第2旋轉速度(例如20rpm)為止。由此，清水清洗水是藉由朝清洗兼脫水槽2的外部被甩開，使清洗兼脫水槽2內的清洗物W貼附在清洗兼脫水槽2的內壁面。在此，在清洗兼脫水槽2內被投入很多的清洗物W的情況時，結束清水清洗過程之後，清洗物W是具有成為呈山型***的形態(第5圖參照)，具有藉由預脫水而使清洗物W的一部分爬上槽蓋18。As shown in FIG. 12, in step S311, the control unit 19 executes a dehydration process. In this dehydration process, the fresh water washing water in the fresh water washing process (S306) is opened, and the drain valve 13 is opened to be discharged outside the machine, and pre-dehydration is performed after the discharge. This pre-dehydration is the same as the pre-dehydration in step S306. After the rotation speed of the washing and dewatering tank 2 reaches the first rotation speed (for example, 400 rpm), the rotation speed of the washing and dewatering tank 2 is reduced to be higher than the first rotation speed. Up to a low second rotation speed (for example, 20 rpm). Thus, the clean water washing water is thrown away to the outside of the washing and dewatering tank 2, and the washing object W in the washing and dewatering tank 2 is adhered to the inner wall surface of the washing and dewatering tank 2. Here, when a large amount of the washing object W is put into the washing and dewatering tank 2, after the clean water washing process is finished, the washing object W has a mountain-shaped hump (refer to FIG. 5), and has Dehydration causes a part of the laundry W to climb on the tank cover 18.
在此，在第2實施例中，在預脫水後實行旋轉給水。在此旋轉給水中，與步驟S306的旋轉給水1同樣地，對於從清洗兼脫水槽2爬上槽蓋18的清洗物W加水。此時，包含水的清洗物是藉由水的重量而再度朝清洗兼脫水槽2內返回。Here, in the second embodiment, the rotary feed water is executed after the preliminary dehydration. In this rotary feedwater, water is added to the washing | cleaning material W which climbed from the washing-and-dehydration tank 2 to the tank cover 18 similarly to the rotary feedwater 1 of step S306. At this time, the washing material containing water is returned to the washing and dewatering tank 2 again by the weight of the water.
且在脫水過程中的旋轉給水，也藉由使清洗兼脫水槽2一邊旋轉一邊朝清洗物W給水，就可以對於槽蓋18的圓周方向的整體加水，即使清洗物W是由複數處爬上槽蓋18的情況，也可以將爬上的複數處的清洗物W返回至清洗兼脫水槽2內。且，在旋轉給水時藉由使清洗兼脫水槽2由比第1旋轉速度更低的第2旋轉速度(例如20rpm)旋轉，比清洗兼脫水槽2是由高速旋轉的情況相比，可以更抑制水朝周圍飛散並且可以將水有效率地滲透清洗物W。In addition, the rotating feed water during the dehydration process can also supply water to the entire circumference of the tank cover 18 by rotating the washing and dewatering tank 2 while rotating to the washing object W, even if the washing object W climbs up from a plurality of places. In the case of the tank cover 18, the washing | cleaning object W which climbed in several places may be returned to the washing-and-dehydration tank 2. In addition, by rotating the washing and dewatering tank 2 at a second rotation speed (for example, 20 rpm) lower than the first rotation speed during the rotation of the feed water, the washing and dewatering tank 2 can be more suppressed than when the washing and dewatering tank 2 is rotated at a high speed. The water scatters toward the surroundings and can efficiently penetrate the washings W.
且旋轉給水地將清洗物W朝清洗兼脫水槽2內落入後，移動至最終脫水。在此最終脫水中，將清洗兼脫水槽2上昇至比第1旋轉速度(例如400rpm)更高的第4旋轉速度(例如700rpm)為止。即使從此狀態進行了脫水，因為從清洗物W已移動的狀態(清洗兼脫水槽2的內壁面貼附的狀態)開始脫水，所以使清洗物W不會大移動。因此，清洗物W不會再度爬上槽蓋18。In addition, after rotating the feed water, the washing object W is dropped into the washing and dewatering tank 2 and then moved to the final dehydration. In this final dehydration, the washing and dewatering tank 2 is raised to a fourth rotation speed (for example, 700 rpm) higher than the first rotation speed (for example, 400 rpm). Even if dehydration is performed from this state, since the washing object W has moved (the state where the inner wall surface of the washing and dewatering tank 2 is attached), the washing object W is not moved much. Therefore, the cleaning object W does not climb on the tank cover 18 again.
如此第2實施例的洗衣機1，是藉由控制單元19，而在脫水過程中的預脫水後(第12圖的步驟S311參照)從給水盒26朝清洗物W進行給水。由此，在脫水過程中，因為可以抑制清洗物W進入清洗兼脫水槽2及外槽7之間的間隙S(第2圖參照)，所以可防止清洗物W的破損。且，因為可以抑制從清洗兼脫水槽2躥出的清洗物W與洗衣機1內的零件接觸，所以可以抑制洗衣機1故障。As described above, the washing machine 1 according to the second embodiment is supplied with water from the water supply box 26 toward the washing object W by the control unit 19 after the pre-dehydration in the dehydration process (refer to step S311 in FIG. 12). Accordingly, in the dewatering process, the washing object W can be prevented from entering the gap S (refer to FIG. 2) between the washing and dewatering tank 2 and the outer tank 7, so that the washing object W can be prevented from being damaged. In addition, since the washing object W scooped out from the washing and dewatering tank 2 can be prevented from coming into contact with the components in the washing machine 1, the washing machine 1 can be prevented from malfunctioning.
且在第2實施例中，控制單元19，是藉由將脫水過程中的脫水分開複數次地實行，在預脫水(其一的脫水)及最終脫水(其他的脫水)之間進行朝清洗物W的給水(旋轉給水)來實行修正清洗物W朝槽蓋18爬上的控制(第12圖的步驟S311參照)。由此，因為可以藉由預脫水來抑制清洗物W再度爬上，所以成為可將最終脫水時的旋轉速度提高地脫水。Furthermore, in the second embodiment, the control unit 19 executes the dehydration in the dehydration process several times separately, and performs the cleaning between the pre-dehydration (the first dehydration) and the final dehydration (the other dehydration). The feed water (revolving feed water) of W is used to execute control for correcting the climbing of the washing object W toward the tank cover 18 (refer to step S311 in FIG. 12). This can prevent the washing object W from climbing up again by the pre-dehydration, so that the spin speed at the time of final dehydration can be increased.
又，本發明不限定於前述的實施例，在不脫離本發明的宗旨範圍可以進行各種變更。取代前述的第1實施例的步驟S307而改成第2實施例的步驟S311也可以。且，取代第1實施例的步驟S310而改成第2實施例的步驟S311也可以。The present invention is not limited to the aforementioned embodiments, and various changes can be made without departing from the scope of the present invention. Instead of step S307 of the first embodiment described above, step S311 of the second embodiment may be changed. In addition, instead of step S310 of the first embodiment, step S311 of the second embodiment may be changed.
且在第12圖的第2實施例中，取代步驟S306而改成第10圖的步驟S309，只有在脫水過程(最終脫水過程)，進行抑制清洗物W朝槽蓋18爬上的處理(預脫水及旋轉給水)也可以。Furthermore, in the second embodiment of FIG. 12, instead of step S306, step S309 of FIG. 10 is performed. Only in the dehydration process (final dehydration process), a process for inhibiting the washing material W from climbing up to the tank cover 18 (pre-processing Dewatering and rotary feed water) are also available.
且在前述的實施例中，雖舉例說明了具備肋25的洗衣機1的例，但是不具備肋25的洗衣機也可以。該情況，將預脫水、脫水、最終脫水的旋轉速度的尖峰下降較佳。Moreover, in the said embodiment, although the example of the washing machine 1 provided with the rib 25 was illustrated as an example, the washing machine which does not have the rib 25 may be sufficient. In this case, it is preferable to reduce the spikes in the rotation speed of the pre-dehydration, dehydration, and final dehydration.
且在前述的實施例中，雖舉例說明了預脫水後的清洗兼脫水槽2的旋轉速度是成為低速(20rpm)的情況的例，但是旋轉速度是0的構成也可以。Furthermore, in the foregoing embodiment, the example in which the rotation speed of the washing and dewatering tank 2 after the pre-dehydration is set to a low speed (20 rpm) has been described as an example, but a configuration in which the rotation speed is 0 may be used.
