[0020] First, refer to Figure 1 to Figure 3 The first embodiment will be described. exist figure 1 The schematic structure of the whole of what is called a vertical shaft type washing machine is shown in . The shell of the washing machine body 1 of the washing machine includes a rectangular box-shaped outer case 2 , a platen 3 arranged at the bottom of the outer case 2 , and a top cover 4 installed on the top of the outer case 2 . A tank 5 is accommodated inside the outer case 2 . In this case, the tank 5 includes a bottomed cylindrical water tank 6 with an open top, and a bottomed cylindrical rotary tank 7 that is rotatably disposed in the water tank 6 and has an open top. As will be described later, the rotary tank 7 rotates around the dehydration shaft 21 directed in the vertical direction.
[0021] The water tank 6 in the tank 5 is elastically suspended and supported by an elastic suspension mechanism 10 made of synthetic resin and having a hanging rod 8 and a spring ...

[0064] Next, refer to Figure 4 A second embodiment will be described. In this embodiment, the tank cleaning operation as described above is performed during draining in the rinsing process. In the state where the rinsing operation by the agitation by the agitator 17 is completed, water is accumulated in the water tank 6 .
[0065] In the drainage / dehydration process, the control device 35 first opens the drain valve 25 to start drainage (step B1), opens the clutch of the drive mechanism 19, and closes the brake to make the rotary tank 7 rotatable (step B2). The control device 35 continues to discharge water until the water level in the tank 5 reaches the preset tank cleaning action and starts the water level L3 (refer to figure 1 ) until (step B3). The tank cleaning operation start water level L3 in this case is set slightly higher than the tank cleaning operation start water level L2 at the time of water supply in the first embodiment.

[0071] Next, refer to Figure 5 as well as Figure 6 , and the third embodiment will be described. In this embodiment, the tank cleaning operation is performed after the normal washing operation is completed. When performing the tank cleaning operation after the normal washing operation, for example, the user may set the mode in advance by operating the operation key 33 on the operation panel 32 before starting the washing operation.
[0072] exist Figure 5 In the normal washing operation, until the final dehydration is completed, the control device 35 ends the washing operation (step C1), and notifies the completion of the washing operation through a notification unit such as a buzzer (step C2). Based on the notification, the user takes out the laundry in the rotary tub 7 . The user needs to open the outer cover 30 and the inner cover 12 if he wants to take out the laundry in the rotary tank 7 . In addition, the user closes the inner cover 12 and the outer cover 30 afte...
