Washing machine control method, controller and washing machine

Abstract

The embodiment of the invention provides a washing machine control method, a controller and a washing machine so that drainage time delay can be set more accurately and relates to the field of household appliances. According to the specific scheme, the method comprises the steps of determining first water injection time and second water injection time, wherein the first water injection time is the time for increasing the water level from 0 to a preset water level value at a certain water injection rate, the second water injection time is the time for increasing the water level from a second water level value to a first water level value at the water injection rate, the preset water level value is equal to or smaller than the second water level value, and the second water level value is smaller than the first water level value; determining reference time, wherein the reference time is the time for reducing the water level from the first water level value to the second water level value during drainage; determining drainage time delay corresponding to the preset water level value according to the first water injection time, the second water injection time and the reference time, wherein the drainage time delay is in positive correlation with the reference time. The washing machine control method, the controller and the washing machine are used for manufacturing of washing machines and controllers.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a washing machine control method, a controller and the washing machine. Background technique [0002] A complete laundry process of the washing machine usually includes three links of washing, rinsing and dehydration, and drains water before each rinse and spin-drying. [0003] Existing washing machine, drainage process such as figure 1 As shown, open the drain valve to start draining, when the water level drops to the reset water level, start timing, when the timing reaches the drain time delay, close the drain valve to stop the draining process. Wherein, the size of the drainage time delay is a fixed value. [0004] In practice, after the washing machine has been used for a long time, due to reasons such as the blockage of the drain valve or the drain pipe, the time required to actually complete the drainage is not always constant, resulting in the following problems in the exi...
