A 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 reference water volume and water volume corresponding to a preset water level, wherein the reference water volume is the difference between water volume corresponding to a first water level and water volume corresponding to a second water level, the second water level is lower than the first water level, and the preset water level is equal to or lower than the second water level; determining reference time, wherein the reference time is the time for reducing the water level from the first water level to the second water level during drainage; determining drainage time delay corresponding to the preset water level according to the reference water volume, the reference time and the water volume corresponding to the preset water level, 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...
