Description

Door lock device with door opening induction

Technical Field

The invention relates to the technical field of electric fittings, in particular to a door lock device with door opening induction.

Background

The door lock of the household appliance is used for keeping the door of the household appliance in a closed and locked state. Such household appliances are for example washing machines, laundry dryers, dishwashers and the like. The existing door lock is used when the household appliance door is not closed or is in a closed state but not closed in place; at the moment, the door of the household appliance cannot be normally locked by operating or starting the program, and abnormal alarm occurs. In order to solve the problems of the existing door lock, whether the household appliance door is in the closed state or not needs to be perceived and identified. When the door of the household appliance is in an open state before the device is operated or started, the door lock device cannot perform operation or start operation program. Meanwhile, when the door is locked and then forcibly opened, the main circuit cannot be powered off by the existing door lock, and the household appliance still continues to work after the door is forcibly opened, so that articles in the equipment fly out to cause personnel injury.

The chinese patent document "CN207212013U" discloses "a door lock switch for an electric appliance". The door lock switch of the electric appliance comprises a shell and a lock hook, wherein the lock hook is erected inside the shell and can circumferentially rotate, a torsion spring is connected between the shell and the lock hook, a locking opening corresponding to the position of the lock hook is formed in the shell, a door lock on a door of a power supply device can be inserted into the locking opening, a door lock device is arranged inside the shell and comprises a fixed seat and a locking slide block arranged inside the fixed seat, an electric driving structure for driving the locking slide block to slide in the length direction is arranged inside the fixed seat, an on-off slide block capable of sliding in the length direction is arranged inside the shell, a sliding groove is formed in the on-off slide block, a guide projection matched with the sliding groove is arranged at the back of the locking slide block, the on-off slide block can be driven to slide by the locking slide block, and the on-off slide block is used for controlling locking of the lock hook.

However, the above-mentioned patent only fulfills the basic function of a door lock: the coil is electrified and locked, and the coil is electrified again to unlock; whether the whole machine door cover is closed or not can not be detected, and equipment misjudgment and alarm are easily caused; after the door is opened forcefully, the main circuit cannot be powered off, if the door is opened by mistake, the equipment still works, the washed object can be damaged if the equipment is light, and personnel injury can be caused if the equipment is serious, so that the situation needs to be solved.
