Self-cleaning control method of washing machine and washing machine

Abstract

The invention discloses a self-cleaning control method of a washing machine. The method comprises the following steps: when the water inflow is lower than a set value, a control unit of the washing machine controls an inner barrel of the washing machine to rotate and the rotating inner barrel hits a water flow to self-clean inner and outer barrels; and when the water inflow time reaches the set time or the water inflow is higher than the set value, the control unit of the washing machine controls an impeller of the washing machine to rotate and stir and stir water inflow to form a rotary water flow to self-clean the inner and outer barrels. The self-cleaning control method of the washing machine disclosed by the invention adopts different self-cleaning modes according to different water inflows in the water inflow process of the washing machine, so that the self-cleaning water consumption is saved and the self-cleaning time is shortened besides the self-cleaning effect of the washing machine is enhanced.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine self-cleaning control method and the washing machine. Background technique [0002] After the existing washing machine has been used for a period of time, a large amount of dirt will adhere to the outer surface of the inner cylinder and the inner surface of the outer tub, such as oil, lint, bacteria and other impurities. Many impurity particles are easy to adhere to because of their small quality. On the inner drum and outer drum of the washing machine, the user cannot see impurities, thinking that the inner drum of the washing machine is very clean, but in fact there are a lot of dirt and bacteria attached to the outer surface of the inner drum and the inner surface of the outer drum. Because of humidity, more bacteria will grow, which will cause mildew and odor problems. Even during washing, impurities will adhere to the clothes, which is not conducive to the h...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that in the above-mentioned patents, the self-cleaning of the washing machine is realized only by the high-speed rotation of the inner cylinder, so it is impossible to enter too much water, because too much water is not conducive to the high-speed rotation of the inner cylinder, so its self-cleaning effect is limited, and it is easy to waste a lot of water. water, because more water needs to be discharged to prevent too much water from being unfavorable to the rotation of the inner cylinder

[0005] On the other hand, its description discloses that after detecting that the drum washing machine has entered water to the set water level, the inner cylinder is controlled to perform cold water self-cleaning washing at the first beat. During this period of time, the inner bucket has been in a waiting state, thus wasting a lot of cleaning time
