Embodiment 1

[0046] Such as figure 1 As shown, the washing machine of this embodiment includes a washing tub that can be used to hold water during the washing process and a washing water level detection device for detecting the water level in the washing tub; For the outer tub, in this embodiment, only the water collecting device is installed at the bottom of the washing tub. During the laundry process, the drain outlet of the washing tub is blocked by the drainage device. During the whole washing process, if the drainage device is not properly blocked, the washing tub may leak. , thereby affecting the washing effect.

[0047] The control method of this embodiment includes: the control method includes: during the washing process of the washing machine, the washing water level detection device detects the water level value within a certain time interval, and determines whether the washing tub is leaking according to the change trend of the water level value.

[0048] The control method of ...

Embodiment approach 1

[0058] Embodiment 1, the bottom of the washing tub is provided with a drain port, and the washing machine includes a water collecting device for collecting the water discharged from the washing tub, and a drainage device is arranged in the water collecting device, the drainage device includes a valve plug, and the valve plug moves up and down to open / close the drain of the washing tub;

[0059] When the washing machine judges that the washing tub is leaking, the laundry process is suspended, and the valve plug of the control drainage device moves down a certain distance h (h is a set value), and moves up to the highest point again to block the drain of the washing tub.

[0060] Further, the drain device has a valve plug stroke H capable of opening the drain port of the washing tub, and the setting of h satisfies: h

Embodiment approach 2

[0061] Embodiment 2, the drainage device has a valve plug stroke H that can open the drain port of the washing tub. When the set value of h is greater than or equal to the valve plug stroke H, the washing machine is controlled to replenish water during the washing process.

[0062] Method 1 Since the valve plug moves down distance h is less than the valve plug stroke H, the drain on the washing bucket will not be opened, and the water in the inner bucket will not be less, which will have little impact on the washing effect; Method 2 When the plug stroke is H, the drain port on the washing tub will be opened, and the reduction of water volume will affect the washing effect, so supplementary water is performed to ensure the washing effect.

[0063] As an implementation of this embodiment, the bottom of the washing tub is provided with a drain port, and the washing machine includes a drainage device for opening / closing the drain port of the washing tub, and the control method incl...

Abstract

The invention provides a control method of a washing machine. The washing machine comprises a washing drum capable of containing water in the washing process and a washing water level detection devicecapable of detecting the water level in the washing drum. The control method comprises the following steps: in the washing process of the washing machine, the washing water level detection device detects the water level value in a certain time interval, and whether the washing drum leaks is judged according to the change trend of the water level value. According to the control method, in the washing process, whether the washing drum leaks is judged according to the change trend of the water level value in a certain time interval, and the washing effect is prevented from being influenced by water leakage of the washing drum.

Description

technical field [0001] The present invention relates to the technical field of laundry equipment, in particular to a control method for a washing machine. Background technique [0002] A washing machine is designed as a device for washing clothes by using electricity. In general, a washing machine includes: a tub for containing washing water; a rotary tub rotatably installed inside the tub; a pulsator rotatably installed in the rotary tub The bottom; motor and clutch, are configured to rotate the rotating barrel and pulsator. When the rotary tub and the pulsator rotate in a state that laundry and detergent are introduced into the rotary tub, the pulsator agitates wash water together with the laundry introduced into the rotary tub, thereby removing stains from the laundry. [0003] In order to increase the washing capacity of the washing machine, a larger rotary tub is required, that is, the height or diameter of the rotary tub needs to be increased. If the rotary tub has a...
