By arranging the drainage structure, and the drainage device and the detection device 801 are both electrically connected with the main control device 800, the main control device 800 controls the opening or the openness of the drainage device according to the water level height in the water collection structure detected by the detection device 801. When the water level in the water collecting structure is higher, the drainage device is opened or the opening degree of the drainage device is increased, quick drainage is realized, and when the water level returns to a lower position or no water exists, the drainage device is closed or the opening degree of the drainage device is reduced, and drainage is stopped or the drainage quantity is reduced.
The drainage device can be arranged independently and used for draining water in case of failure, and can also be structurally modified on a drainage pipe of the original washing machine.
Case of opening of the drain:
during water intake, since the second water discharge port 204 is blocked by the blocking device 205, substantially no water is present in the water collecting structure, and the main control device controls the water discharge device to be in a closed state by electrically connecting the water discharge device with the main control device 800. If the water level control element such as a flowmeter or the like fails or the plugging device 205 fails to cause water flow to overflow, the detection device 801 controls the opening of the drainage device to drain water in the water collection structure when detecting that the water level in the water collection structure is too high.
During the drainage and dehydration process, the blocking device 205 opens the second drainage port 204 to drain water into the water collection structure, the main control device 800 controls the drainage device to open to drain the water in the water collection cavity 400,
or, when the detection device detects that the liquid level in the water collecting cavity 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 drainage device to be opened to realize drainage.
During the drainage and dehydration process, if the drainage device is not started, and the detection device 801 detects that the liquid level is too high, the detection information is transmitted to the main control device 800, and the main control device 800 controls the drainage device to be started.
Further, the drainage device includes a drainage pipe 401 communicated with the water collecting structure, a control structure 802 for controlling the drainage pipe 401 to be conducted/cut off is arranged on the drainage pipe 401, the control structure 802 is communicated with the drainage pipe 401, when the control structure 802 is opened, the drainage pipe 401 is conducted to discharge the washing water, when the control structure 802 is closed, the drainage pipe 401 is cut off, the washing water cannot be discharged, the control structure 802 is electrically connected with the main control device 800, and the main control device 800 controls the control structure 802 to be opened/closed according to the water level in the water collecting structure detected by the detection device 801.
By arranging the control structure 802 on the drain pipe 401, the control structure 802 is electrically connected with the main control device 800, and the main control device 800 controls the control structure 802 to be opened/closed according to the water level in the water collecting structure detected by the detection device 801, so as to realize whether the water in the water collecting structure is drained or not.
Preferably, the drain pipe 401 communicates with the bottom wall of the water collecting chamber 400, thus facilitating drainage.
The control structure 802 can be of various types, explained by way of example with solenoid valves and a drain pump:
the first scheme is as follows: the control structure 802 is an electromagnetic valve, the electromagnetic valve is electrically connected with the main control device 800, and the main control device 800 controls the opening/closing of the electromagnetic valve according to the water level in the water collection structure detected by the detection device 801, so as to realize the conduction/cut-off of the drain pipe 401.
For example, in the water inlet state, since the blocking device 205 blocks the second water outlet 204, there is substantially no water in the water collecting chamber 400, the solenoid valve is in the closed state, when there is a fault, the water level in the water collecting chamber 400 rises, and when the water level is too high, the main control device 800 controls the solenoid valve to open, so that the water outlet pipe 401 is conducted, and the water in the water collecting chamber 400 is discharged.
The solenoid valve is preferably a normally closed solenoid valve, which is closed in a normal state.
Further, the height of the drain pipe 401 in the vertical direction is lower than the upper end of the water collecting chamber 400, preferably, the height of the drain pipe 401 in the vertical direction is lower than the communication opening of the water collecting chamber 400 and the drain pipe 401, and if the communication opening is provided on the bottom wall of the water collecting chamber 400, the drain pipe 400 is preferably lower than the bottom wall of the water collecting chamber 400.
The structure of the scheme is very suitable for the washing machine which adopts a drainage mode to drain water.

When the water level in the water collecting structure is too high, the main control device 800 controls the drainage pump to be opened, the water in the water collecting structure is sucked out, the drainage is realized, when the water level falls back to the safe height, the main control device 800 controls the drainage pump to be closed, and the water is not discharged any more. The structure is very suitable for the washing machine which adopts the upper drainage mode to drain water.
Further, the detecting device 801 is a water level sensor or a pressure sensor disposed in the water collecting structure. The water level in the water collecting structure is detected through the water level sensor or the pressure sensor, and the sensitivity is high.
