Embodiment Construction

[0034] The invention discloses a water level correction control method for a washing machine, comprising the following steps:

[0035] S1. After the clothes to be cleaned are put into the washing machine, manually select the target water level;

[0036] S2. Automatically perform weight sensing to determine the actual water level;

[0037] S3. Set the safety range of the target water level and the actual water level;

[0038] S4. Calculate the error value between the target water level and the actual water level;

[0039] S5, determine whether the error value is greater than or equal to the safety range, if so, set the actual water level as the target water level, if not, the target water level will remain unchanged.

[0040] Correspondingly, the present invention also discloses a water level correction control system for a washing machine, comprising:

[0041] The target water level selection unit is used to manually select the target water level;

[0042] The actual water...

Abstract

The invention discloses a washing machine water level correction control method and system. The method comprises S1, selecting a target water level after clothes to be washed are put in the washing machine; S2, performing weight sensing automatically to determine the actual water level; S3, setting the target water level and actual level safety range; S4, calculating the error of the target water level and the actual water level; S5, determining whether the error is larger than or equal to the safety range, setting the actual water level as the target water level if the error is larger than or equal to the safety range, otherwise, keeping the target water level unchanged. By means of the method and the system, the situation of the large difference between the load actually needed water level and the current selected water level can be prevented effectively, clothes and the washing machine are protected, resources of water and electricity are saved, and the cleanness ratio is guaranteed.

Description

technical field [0001] The invention relates to the technical field of washing machine control, in particular to a water level correction control method and system for a washing machine. Background technique [0002] After the washing machine user manually selects the water level, if the currently manually selected water level is much lower than the water level required by the actual load, the clothes will be severely worn during the washing process, and even the motor will be blocked, causing damage to the clothes or the washing machine. The water level is much higher than the water level required by the actual load, which will lead to waste of resources such as water and electricity during the washing process, prolonging the washing time and unsatisfactory washing ratio. [0003] Water level sensors are commonly used in the prior art to control the water level. The water level sensor is equivalent to a pressure switch. When a pressure value is set, the water pressure will...
