Washing machine control method and washing machine

Abstract

The invention discloses a washing machine control method and a washing machine, and relates to the field of washing equipment. The washing machine comprises a washing barrel and a water collecting device in communication with a water outlet of the washing barrel, wherein the height of the top of the water collecting device is smaller than that of the top of the washing barrel; the washing machinefurther comprises a drain valve used for controlling opening and closing of the water outlet; a water level detection device is arranged in the water collecting device; a water level interval of the water collecting device is preset in the washing machine; and in a drainage process, when the water level in the water collecting device reaches a critical water level of the water level interval, thewashing machine controls the drain valve to act. The amount of water in the water collecting devices is limited within one interval, washing water can be prevented from overflowing due to the fact that the water amount is too high, and it also can be guaranteed that the certain water amount is kept in the water collecting device to prevent the water discharge time from being too long; through thenumber of opening and closing times of the water outlet in the water collecting device, the washing machine can deduce the amount of clothes, so that dehydration time can be guided.

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 order to solve the problem of dirt residue and the problem of increasing the capacity of the washing machine, there is a water collecting device outside the washing tub in the prior art, and the design of the traditional outer tub is cancelled. During the washing process, there is no water in the water collecting device. The water collecting device is used to receive the water discharged from the washing tub when the washing tub is draining, and finally discharge the water to the outside of the washing machine. [0003] Since the water collecting device has a lower height than the traditional outer tub, there may be a high water pressure in the washing tub during the draining process of the washing tub. When the water level is high, the water in the water collecting device has n...

Problems solved by technology

[0003] Since the water collecting device has a lower height than the traditional outer tub, there may be a high water pressure in the washing tub during the draining process of the washing tub. When the water level is high, the water in the water collecting device has no time to drain out of the washing machine. , causing water to overflow from the top edge of the catchment, causing damage to the interior of the unit

[0004] The general way to solve the overflow problem of the water collection device is to drain water by setting a fixed sequence of opening and closing the drain valve. However, due to the different water volumes in the washing tub, the fixed sequence cannot adapt to the drainage process of different water volumes, and may still cause overflow. Or the problem of excessive drainage time

Even if the water volume is judged by the water inlet flowmeter, the washing water will overflow due to the accuracy of the flowmeter
