The invention relates to a washing machine control panel aging experimental equipment and experimental method. The washing machine control panel aging experimental equipment is characterized by comprising a square wave generation module which can generate square wave signals of different frequencies to simulate water level frequency in a washing machine barrel, a test water drainage valve, a test water inlet valve and a test motor which have the same model number and brand with those of the water drainage valve, the water inlet valve and the motor of an actual washing machine, an electric generator and resistive loads. Compared with experimental equipment in the prior art, the advantages of the experimental equipment reside in that the water inlet and water drainage process of the washing machine is simulated by using the square wave generation module, the small electric generator is driven by the simulation motor, and then different loads are connected on the electric generator to simulate different motor loads of the washing machine so that the washing machine control panel aging effect can be achieved without using a drop of water, and environment is beatified and cost is saved through the mode.
Description
technical field [0001] The invention relates to an aging experimental equipment and an experimental method for a washing machine control board. Background technique [0002] The washing machine control board aging test is the same as the washing machine aging test, that is, the washing machine control board is installed on the washing machine, and the washing cycle test is carried out for 5000 times. Among them, the washing machine control panel judges the water level by frequency. The higher the water level is, the lower the water level frequency is. On the contrary, the lower the water level is, the higher the water level frequency is. The water level sensor of the washing machine produces different inductive reactance according to the magnitude of the water pressure, and in the water level frequency oscillation circuit, due to the change of inductive reactance, different frequencies are generated, which is called the water level frequency. The washing machine control boa...
