Electric appliance door lock switch

Abstract

The invention provides an electric appliance door lock switch and belongs to the technical field of electric appliance accessories. The electric appliance door lock switch aims at overcoming the defect that in the prior art, a brake sliding block inside an electric appliance door lock switch which is driven by a door latch to achieve automatic locking is prone to abrasion. The electric appliance door lock switch comprises a shell. The shell is provided with a lock opening, wherein the locking opening is used for allowing a door lock on an electric appliance door to be inserted therein. The shell is internally provided with a door lock hook, a lock sliding block, a stop block, a driving block and a driving device. The door lock hook is arranged at the position, corresponding to the lock opening, inside the shell in an erected manner and can rotate in the circumferential direction to be switched between the locked state and the unlocked state. The door lock hook is provided with a driving curved surface with the height difference. A torsional spring is connected to the door lock hook. One end of the stop block is an adjustment end, and the other end of the stop block is a locking end. A stop block spring is connected to the stop block, wherein the stop block spring drives the adjustment end of the stop block to be closely attached to the driving curved surface all the time. The locking end can stop the driving block from sliding. According to the electric appliance door lock switch, the stop block is small in abrasion, the stroke is easy to control, manual unlocking can be achieved, and the good waterproof performance is achieved.

[0002] The door lock of electrical appliances plays a vital role in electrical appliances. When the electrical appliances are working normally, in order to ensure safety, the working space inside the electrical appliances needs to be a closed space, especially for washing machines, dishwashers and other electrical appliances. Open it at will, not only the outside sundries may enter the appliance and cause damage to the appliance, but also people who accidentally touch the internal working parts of the appliance may cause danger and cause unnecessary damage, and if the door lock of the appliance cannot work normally When the lock is guaranteed, it will also cause the items inside the appliance to fly out of the working space, which will seriously affect the product quality of the appliance and bring great inconvenience to normal use.

[0003] In response to the above problems, people have designed various electrical door locks to improve the safety factor of electrical appliances, so that the door can be automatically locked when the electrical appliance is working, and cannot be opened from the inside, and after the door is opened from the outside, the electrical appliance can stop working in time

However, in the existing electrical door lock switch, the automatic locking is usually driven by the door plug, and then the brake slider is pushed after the door plug is inserted into the lock. However, the width of the door plug is relatively wide, and the stroke of the brake slider is too large. The stroke is uncontrollable, and the surface of the door plug is not smooth, which is easy to wear the brake slider, resulting in shortened service life of the electrical door lock switch
