Abstract
The application discloses a household appliance, which comprises a shell, a circuit board and electronic devices arranged in the shell. The circuit board comprises a wiring terminal, a control unit and at least one of a first electrostatic protection unit and a second electrostatic protection unit. The wiring terminal is used for electrically connecting with the electronic devices to receive signals from the electronic devices or send signals to the electronic devices. The first electrostatic protection unit is electrically connected with the wiring terminal, the first electrostatic protection unit comprises a first resistor and a first capacitor, the first resistor and the first capacitor are connected in series between the wiring terminal and the ground, and a connection point between the first resistor and the first capacitor is electrically connected with the control unit. The second electrostatic protection unit is electrically connected with the wiring terminal, the second electrostatic protection unit comprises a transient voltage suppression diode, and the transient voltage suppression diode is electrically connected between the wiring terminal and the ground. In this way, the risk of damage to the circuit board can be reduced.
