A door lock and an electrical appliance using the door lock. The door lock comprises: a switch housing; a pen core-like mechanism disposed in the switch housing; a control needle (state means) passing out of the pen core-like mechanism; and a manual unlocking pull rod mechanism. The manual unlocking pull rod mechanism is capable of moving towards the control needle and coming into contact therewith. The position of the control needle (state means) indicates the switch state of the door lock, such that when the door lock is in an unlocked position, further pulling of the manual unlocking pull rod mechanism has no effect on the door lock switch mechanism.
