Processing method for reducing shutdown power consumption of washing machine

Abstract

The invention discloses a processing method for reducing shutdown power consumption of a washing machine. The processing method includes the following steps: step 1, detecting a main circuit of the washing machine; 2, analyzing the main circuit of the washing machine; 3, analyzing a zero-cross detection circuit of the main circuit; and 4, designing the new zero-cross detection circuit, the main circuit including a power conversion circuit, a control panel, a power control circuit, the zero-cross detection circuit and a voltage stabilization control circuit, and the new zero-cross detection circuit including a photoelectric coupler, wherein one end of the photoelectric coupler is connected with a null line N end while the other end is connected with the AC_L_TEMP, a diode is arranged between the photoelectric coupler and the AC_L_TEMP, a safety resistor is arranged between the photoelectric coupler and the null line N end, and the photoelectric coupler is connected with a voltage stabilizing diode in parallel. The processing method has the beneficial effects that the shutdown power consumption of the washing machine is reduced through the new zero-cross detection circuit, and the work of the washing machine is not influenced at all.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a processing method for reducing power consumption of a washing machine when it is turned off. Background technique [0002] After the household washing machine is installed, it should be fixed in one place and plugged in all the time. When using it, the user directly operates the buttons on the panel. After the washing is completed, the washing machine will automatically shut down. All lights are off and all loads stop working. In fact, the microcontroller and power conversion circuit of the controller are always working, waiting for the user's operation in real time. As long as the washing machine is plugged in, there will be a certain amount of power consumption, that is Shutdown power consumption. Contents of the invention [0003] The object of the present invention is to solve the above problems, and to design a processing method for reducing the power consumptio...
