Abstract

The embodiment of the invention discloses electrical equipment and a control circuit thereof.The control circuit comprises a display circuit, a main control circuit and an isolation circuit; the display circuit is electrically connected to the input endof the isolation circuit; a main control weak power source and the output end of the isolation circuit are electrically connected to the main control circuit respectively. In the electrical equipment and the control circuit thereof, the display circuit generates a first start signal based on a start command from a user, the first start signal is converted into a second start signal through the isolation circuit and is sent to the main control circuit, so that the main control circuit is electrically connected to the main control weak power source, the electric connection between the main control circuit and the main control weak power source is disconnected when the main control circuit receives a command about turn-off or does not receive any operation command within the set time, accordingly the awakening and self-turn-off of the circuit power source are achieved, and the power consumption of the circuit is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of circuits, and in particular to an electrical device and a control circuit thereof. Background technique [0002] For commonly used household appliances, such as washing machines, in order to save electric energy, users usually unplug the plug to disconnect the power supply when not in use, and then plug in the plug to turn on the power supply when in use. Although it can reduce electrical power consumption and save electric energy, but In the long run, it will have a certain impact on the components of electrical appliances. [0003] In the prior art, in order to solve the above problems, a standby circuit is configured in the electric appliance. For example, generally after the power is plugged in, the washing machine starts to be in a standby state. Just need manual operation to start power supply when using washing machine, now washing machine starts to work; [0004] Howev...
