Control system and control method of electrical appliance

Abstract

A control system and control method of electrical appliance is provided, the control system includes a control unit, an exhaust unit and a LED unit. The control unit is coupled to the exhaust unit and the LED unit. When the control unit determines an operating current of an electrical appliance is greater than a first preset current value, the exhaust unit rotates at high speed and the LED unit sends out a first prompt signal. When the operating current is less than a second preset current value and the electrical appliance is in a heat preservation state or is shut down for a first preset time, the LED unit emits a second prompt signal. When the operating current is less than the second preset current value and the electrical appliance is in the heat preservation state or is shut down for a second preset time, the exhaust unit rotates at a low speed. When the operating current is less than the second preset current value and the electrical appliance is in the heat preservation state or is turned off for a third preset time, the exhaust unit stops rotating and the LED unit emits a third prompt signal.
