By providing the water collecting structure, on the one hand, when the water is discharged from the inner tub 200, the water is blocked by the water collecting structure to prevent the water from overflowing. On the other hand, since the water collecting structure is entirely located below the inner tub 200, the water collecting structure is not located. The partial structure between the side wall of the inner tub 200 and the cabinet 100 does not have a limiting effect on the expansion of the inner tub 200, and provides ample space for the expansion of the inner tub 200. By providing the drainage control device, when the amount of water in the water collecting structure is excessive, the water is discharged through the drainage control device, effectively preventing the water level in the water collecting structure from being excessively high and overflowing.

The drain control device includes a main control device 800, a detecting device 801 for detecting a liquid water level in the water collecting structure, and a drain device for discharging water in the water collecting structure, the water collecting structure being entirely located at the The lower portion of the bottom of the inner tub 200, the detecting device 801 and the drain device are electrically connected to the main control device 800, the detecting device 801 detects the water level in the water collecting mechanism and transmits the detection result to the main control device 800, and the main control device 800 is The water level detected by the detecting device controls the drainage of the drainage device.

The washing machine generally further includes a box body 100 and a driving device for driving the inner tub 200 to rotate. The inner tub 200 is disposed in the box body 100. The main control device 800 is generally disposed in the box body 100 and fixedly connected to the box body 100.

Further, the water collecting structure includes a water collecting chamber 400 having an upper opening, an upper end of the side wall of the water collecting chamber 400 is lower than a bottom of the inner tub 200, and an upper opening of the inner tub 200 and the water collecting chamber 400 In connection, the detecting device 801 is disposed in the water collecting chamber 400.

The water discharged from the inner tub 200 is blocked by providing the water collecting chamber 400. Since the upper end of the side wall of the water collecting chamber 400 is lower than the bottom of the inner tub 200, the water collecting chamber 400 is entirely located below the bottom of the inner tub 200. The side wall of the water collecting chamber 400 does not have a structure between the inner tub 200 and the tank 100, and a certain safety distance is not required between the inner tub 200 and the water collecting structure to prevent the inner tub 200 from colliding with the water collecting structure to cause damage. At the same time, it is not necessary to set a safety distance between the water collecting structure and the box 100. Therefore, only the safety distance between the inner barrel 200 and the box 100 can be designed, and the inner barrel 200 barrel diameter can be greatly increased, and the inner barrel 200 can be better realized.

When the drain is dehydrated, the occluding device 205 is opened to discharge the water into the water collecting chamber 400 of the water collecting structure. When water is introduced, if the water level control element such as the flow meter fails, water flows through the top of the balance ring along the wall of the inner barrel 200 to the bottom collection chamber 400, and the water will not only overflow from the collection chamber 400 due to the water inlet. Or, during dewatering and draining, the washing water in the inner tub 200 enters the water collecting chamber 400 from the inner tub 200, and if there is too much liquid, it will overflow from the water collecting chamber 400; or, in the washing process, the inner tub 200 and the water collecting chamber 400 The clogging device 205 is damaged, and the washing water enters the water collecting chamber 400 from the inner tub 200, so that the water does not stop the water from overflowing from the water collecting chamber 400.

By providing a drainage structure, and both the drainage device and the detection device 801 are electrically connected to the main control device 800, the main control device 800 controls the opening or opening of the drainage device based on the water level in the water collecting structure detected by the detecting device 801. When the water level in the water collecting structure is high, the drainage device is opened or the opening degree of the drainage device is increased to achieve rapid drainage. When the water level is retracted to a lower position or no water, the drainage device is closed or the drainage device is opened. Degree, stop draining or reduce displacement.

The drainage device may be provided separately, for the device for draining in case of failure, or for structural modification on the drain pipe of the original washing machine.

When the drain is open:

During the influent process, since the occlusion device 205 blocks the second drain port 204, the water collecting structure is substantially free of water, and the main control device controls the drain device to be closed by electrically connecting the drain device to the main control device 800. . If the water level control element such as the flow meter fails or the occlusion device 205 fails, causing the water to overflow, and the detecting device 801 detects that the water level in the water collecting structure is too high, the opening of the drainage device is controlled to discharge the water in the water collecting structure.

During the drain dewatering process, the plugging device 205 opens the second drain port 204 to discharge the water into the water collecting structure, and the main control device 800 controls the drain device to open to discharge the water in the water collecting chamber 400.

Alternatively, when the detecting device detects that the liquid level in the water collecting chamber 400 of the water collecting structure is too high, the detection information is transmitted to the main control device 800, and the main control device 800 controls the opening of the drainage device to realize drainage.

During the drain dehydration process, if the drain device is not turned on, the detecting device 801 detects that the liquid level is too high, and transmits the detection information to the main control device 800, and the main control device 800 controls the drain device to open.

Further, the drainage device includes a drain pipe 401 communicating with the water collecting structure, and the drain pipe 401 is provided with a control structure 802 for controlling the opening/closing of the drain pipe 401, and the control structure 802 is in communication with the drain pipe 401.

For example, in the water inlet state, since the blocking device 205 blocks the second drain port 204, the water collecting chamber 400 is substantially free of water, and the solenoid valve is in a closed state. When a fault occurs, the water level in the water collecting chamber 400 rises. High, when the water level is too high, the main control device 800 controls the solenoid valve to open, and the drain pipe 401 is turned on to discharge the water in the water collecting chamber 400.
