Washing machine water inlet control method

Abstract

The invention provides a washing machine water inlet control method. A washing machine comprises a washing barrel; the washing barrel independently contains washing water in a washing process; and thecontrol method comprises the steps that in a water inlet stage of the washing machine, the washing machine obtains the load weight of the washing barrel, and the water inlet process of the washing barrel is controlled according to the load weight of the washing barrel. In order to solve the problem that a traditional pressure type water level sensor is difficult to detect and control the water inflow of an existing hole-free inner barrel washing machine, the control method for controlling the water inflow through motor weighing is provided, the water inflow of the washing machine can be accurately controlled without additionally arranging a flow meter, and the cost of the washing machine is reduced.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to a method for controlling water inflow to a washing machine. Background technique [0002] The structures of the existing common washing machines are basically the same, and generally include an outer tub for holding water and an inner tub rotatably arranged inside the outer tub. A large number of water holes or dehydration holes are arranged on the inner tub, and clothes are put into the inner tub , while the outer bucket is used to hold water. The water level detection or water intake control of these ordinary washing machines generally adopts water level sensor detection and control, or through flow meter detection and control. The meter determines the water intake of the washing machine by detecting the flow of water flowing through it. [0003] But for the washing machine of another kind of structure, it comprises the washing bucket that rotatably is ar...

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a washing machine water inlet control method. Aiming at the problem that the existing non-porous inner tub washing machine is difficult to use the traditional pressure water level sensor to detect and control the water inlet volume, a method of controlling the water inlet volume by using motor weighing is proposed. The method realizes accurate control of the water intake of the washing machine without adding additional flowmeters, and reduces the cost of the washing machine. The following technical solutions are adopted:

[0007] In the above scheme, in view of the problem that the existing non-porous inner tub washing machine is difficult to use the traditional pressure water level sensor to detect and control the water intake, a control method using motor weighing to control the water intake is proposed, which realizes the need for no additional flowmeter. Can accurately control the water intake of the washing machine, reducing the cost of the washing machine
