Problems solved by technology

At this time, the washing machine will alarm and shut down due to the slow drainage, and interrupt the laundry, which will cause inconvenience to the user.
Especially if the user uses the reservation function, or the user is not near the washing machine during the laundry, it should be dealt with in a timely manner, so the laundry process cannot be completed
[0006] On the other hand, the drainage time has been set in the program, even if the water in the washing machine bucket has been drained, the next process can only be carried out after the drainage time reaches the set time, which is a waste of time. less than humane requirements

Embodiment Construction

[0024] see figure 1 , the washing machine control method provided by the present invention includes: the washing machine enters the drainage subroutine S1, and first judges whether the initial water level is below the reset water level in step S2;

[0025] According to the judgment result, select the step of draining to end, or perform draining and timing, and store the water level value at the same time;

[0026] If the initial water level is below the reset water level, it means that there is no water in the washing machine or there is very little water in the clothes. If the washing machine is put into the washing machine for dehydration after hand washing, it will enter the stage of draining and timing S31; the judgment stage of whether the draining time reaches 10 seconds S4, When the drainage time reaches 10 seconds, it enters the drainage end stage S5, then exits the stage S12, and enters the dehydration program.

[0027] If the initial water level is higher than the r...

Abstract

The invention relates to a control method of a washing machine, capable of dynamically detecting, recording and comparing water levels. The control method of the washing machine comprises the following steps of: entering a drainage process and comparing and judging an initial water level and an offsetting water level; selecting to end drainage or draining and timing while storing a water level value according to a judging result; detecting and recording the current water level when reaching a set water level comparison period in draining and timing; comparing the current water level with the former stored water level and judging whether the water level changes or not; and selecting a drainage fault alarm or selecting to continuously carry out the drainage process of the next period according to the judging result. Through the technical scheme, the invention can effectively judge the fault degree of the drainage system in time, facilitate users, saves time and improves the utilization rate of the washing machine.

Description

technical field [0001] The invention relates to a washing machine control method, in particular to a fully automatic washing machine equipped with a water level sensor for dynamic detection of the water level, and a method for controlling the drainage process according to the detection and comparison of the water level. Background technique [0002] At present, most of the drainage control methods of fully automatic washing machines adopt the method of directly opening the drainage valve to the set water level by the drainage pump or the traction motor. Under normal circumstances, there will be no problem, but when there is water in the drainage pump or the drainage valve Foreign matter, or even damage to the drain pump or traction motor, will cause slow or even no drainage. [0003] The current program control method is to set a certain drainage time, such as 8 minutes. In the existing drainage control method of a fully automatic washing machine, the washing machine enters...
