Method for controlling water level of washing machine

Abstract

The invention belongs to the technical field of washing machines, and particularly relates to a method for controlling a water level of a washing machine. The method comprises the following steps thatwater supply and drainage instruction information and target water level height information of the washing machine are acquired, wherein the water supply and drainage instruction information comprises a water supply instruction and a drainage instruction, the water supply instruction is used for controlling the washing machine to supply water into a water tub of the washing machine, and the drainage instruction is used for controlling the water tub of the washing machine to drain water out of the washing machine; absolute water level information in the water tub of the washing machine is acquired; and the absolute water level information in the water tub is compared with target water level information, and whether the absolute water level information in the water tub is not less than thetarget water level information is judged, if so, a water supply and drainage stop instruction is generated. According to the invention, the water level in the washing process can be accurately controlled according to the absolute water level information in the water tub of the washing machine.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a method for controlling the water level of a washing machine. Background technique [0002] When the washing machine performs water level control, a pressure detection sensor is often installed inside the washing machine to detect the pressure in the washing machine's water tank, and then convert the pressure into the water level height, so as to obtain the water level height in the washing machine, and then control the water supply and drainage of the washing machine according to the water level height. Take control. [0003] However, the water level in the bucket of the washing machine that can be detected by the current washing machine is affected by the atmospheric pressure. For example, when the washing machine is used on the 30th floor, the atmospheric pressure on the 30th floor is very different from the atmospheric pressure on the first floor. , and...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for controlling the water level of a washing machine, which aims to solve the technical problem in the prior art that the water level cannot be accurately controlled during the washing process because the water level obtained by the washing machine is easily affected by the atmospheric pressure.
