Household appliance control circuit, control method and device and household appliance

Abstract

The invention provides a household appliance control circuit, a control method and device and a household appliance. The control circuit comprises a touch control unit, a main control unit and a powersupply unit. The power supply unit is connected with the main control unit and is used for supplying power to the main control unit. The main control unit is connected with the touch control unit andis used for sending state indication information in normal operation and restarting to continue normal operation after power supply is recovered. The touch control unit is connected with the power supply unit and is used for making the power supply unit stop supplying power to the main control unit when it is determined that the state indication information cannot be obtained from the main control unit and making the power supply unit recover power supply when the temporary suspension of power supply reaches a set duration. When the main control unit of the household appliance cannot operatenormally, the power supply unit is controlled to stop supplying power to the main control unit for a set time length, and then, the power supply unit is controlled to recover power supply to the maincontrol unit. Thus, the problem that the household appliance cannot continue to be used due to the fact that the main control unit cannot operate normally in the prior art is solved, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of household appliances, and in particular to a control circuit, control method, device and household appliances of household appliances. Background technique [0002] With the development of society, people's living standards are constantly improving, and household electrical appliances have become a necessity in people's lives. At present, the hardware design of home appliances in the home appliance industry mostly adopts a single-channel design method. For example, the main control chip and touch chip of home appliances obtain button information (for example, power button, start and pause buttons, etc.) through I2C communication. [0003] However, in the actual use of home appliances, when the main control chip cannot work normally due to internal timing or logic problems, for example, the interface is stuck, black screen, blurred screen, touch is not sensitive, I2C cannot communicate normally a...

Problems solved by technology

[0005] For this reason, this application proposes a control circuit for home appliances. When the main control unit of the home appliance fails to operate normally, the power supply unit is controlled to stop supplying power to the main control unit until a set duration, and then the power supply unit is controlled to resume power supply to the main control unit. In order to make the main control unit continue to operate normally, it solves the problem in the prior art that the main control unit cannot operate normally and the home appliance cannot continue to be used, thereby improving the user experience
