A door lock (100) for locking a door of an electrical appliance, comprising a driving gear (305), a lockpin driving wheel (210), a lockpin (110), and a spring element (510). In the present invention, the lockpin driving wheel (210) is driven by the driving gear (305) to rotate synchronously; and when the lockpin driving wheel (210) is driven to rotate in a second direction by an external force, the lockpin driving wheel (210) overcomes the friction of the spring element (510) against the inner top of the lockpin driving wheel (210) and the inner bottom of the driving gear (305), so that the driving gear (305) is not driven by the lockpin driving wheel (210), and thus the lockpin driving wheel (210) slidably rotates on the driving gear (305). |
