Abstract
The invention provides a drying mechanism which comprises an air duct, a heater, a fan, a fan motor, a circuit control board and a centrifugal switch for controlling a heating circuit to be connected or disconnected, wherein the circuit control board is provided with the heating circuit for controlling the heater to be on or off and a motor circuit for controlling the fan motor to be on or off; the heating circuit is in parallel connection with the motor circuit, the heater is in series connection with the heating circuit, and the fan motor is in series connection with the motor circuit; and the centrifugal switch is in series connection with the heating circuit and is coaxially connected with the fan motor. When the fan motor rotates, the centrifugal switch is switched on, and when the fan motor stops rotating, the centrifugal switch is switched off. Only on the premise that the fan motor rotates can the heater work. When the circuit control board starts the fan motor and the fan motor cannot rotate due to faults, the centrifugal switch cannot be switched on, and the heater cannot perform heating normally. It is guaranteed that the problem that only the heater works, so that the severe local heating is caused and the drying mechanism is burned down is solved, and hidden fire danger is reduced. The invention further provides a washing machine.
