Abstract: The refrigerator is detected by the main control board software to judge the current when the water pump is supplying water, and then judge whether there is water in the water storage box. When it is determined that there is water in the water box, the heating wire of the water box works normally according to the startup rate; On the contrary, the heating wire of the water box is closed. The scheme can not only solve the problem of shortage of infrared sensors under the background of global epidemic, but also more accurately control the start and stop of heating wire of water box, so as to achieve the purpose of energy saving of refrigerator.
