The present application discloses a cooking appliance, belonging to the field of cooking appliances. The cooking appliance comprises a main unit, a door, a door hook, a
fastener, a lock, and an operating unit. The door is mounted on the main unit, the door hook is mounted on the door, the
fastener is pivotally mounted on the main unit about a first axis and engages with the door hook. The
fastener is provided with a locking hole and a strip hole along the first axis, the strip hole extending circumferentially along the fastener's pivot axis. The lock slides along a first direction between a first position and a second position, the first direction being parallel to the first axis. The lock comprises a connecting arm and a locking
flange. When the lock is in the first position, the locking
flange is engaged in the locking hole, locking the fastener. When the lock is in the second position, the locking
flange extends out of the locking hole. The connecting arm can slide from the locking hole to the strip hole, unlocking the fastener. The operating unit drives the lock to slide from the first position to the second position. The double-lock design requires users to complete a two-step unlocking process before opening the door, thereby reducing the risk of children being scalded by opening the door and contacting heated food and beverages.
