Abstract

The invention discloses a control method of a washing machine and the washing machine. The washing machine comprises a washing barrel with a water outlet and a water collecting device used for collecting water discharged by the washing barrel; and the washing machine further comprises a washing barrel drainage valve used for controlling the water outlet to be opened and closed. The control method comprises the steps that a low critical water level of the water collecting device is preset in the washing machine; and in the drainage process, when it is detected that the water level in the water collecting device drops to the low critical water level, the washing machine controls the washing barrel drainage valve to be opened after the time delta t is delayed, wherein delta t is a set value and is the time required by emptying all the water in the water collecting device from the low critical water level under the condition that the washing barrel drainage valve is closed. According to the washing machine, when the water level in the last stage of each drainage period drops to the low critical water level, the drainage valve is opened after the time delta t is delayed, so that the highest point of the water level in the water collecting device in the next drainage period is lower than that in the previous period, and the overflow problem is avoided.

Description

technical field

[0001] The invention belongs to the field of washing equipment, and in particular relates to a washing machine control method and the washing machine. Background technique

[0002] In the existing washing machine without water between the inner water collecting device, the original water collecting device is set as a water collecting device whose height is much smaller than that of the washing tub. When washing, there is no water in the water collecting device, and the water collecting device is used for washing When the tub is draining, it receives the water discharged from the washing tub, and finally discharges the water to the outside of the washing machine.

[0003] Because the drainage pipe on the water collecting device is easy to be blocked or the outlet of the floor drain is small, the drainage of the water collecting device is slow, and the water collecting device has a lower height than the traditional water collecting device, so in the process of ...
