Description

A door lock device for a washing machine and a washing machine with the door lock device

technical field

The invention belongs to the technical field of washing machines, and in particular relates to a door lock device of a washing machine and a washing machine with the door lock device.

Background technique

As we all know, the washing machine door lock plays a vital role in the washing machine. In order to ensure safety, the washing machine needs to be connected with the main body of the washing machine through the door lock of the washing machine when the washing machine is doing normal laundry work, so as to prevent the door cover from being opened at will when the washing machine is working; usually, the washing machine includes a door for opening and closing the laundry inlet. , the laundry inlet provides a laundry passage for allowing the user to drop laundry into the washing tub. The user can open the door of the washing machine to put the laundry into or take it out of the washing tank, and close the door of the washing machine to run the washing machine to perform washing operations such as washing, rinsing, and dehydration.

At present, the existing washing machines on the market are all automatic washing machines controlled by the main control board. Most of them adopt centrifugal dehydration with high speed and large moment of inertia. security. On the one hand, it prevents the water and clothes in the washing machine from running out of the inner drum of the washing machine due to the opening of the machine cover during the washing process; on the other hand, it prevents the clothes from being thrown out during high-speed dehydration, or the danger caused by human contact with the rotating inner tub.

The Chinese patent application number CN201610403774.8 discloses a door lock device for a washing machine. A door lock device for a washing machine according to an embodiment of the present invention includes: a housing including a housing and a cover covering the upper surface of the housing and combined with the housing, and is provided with a door lock pin hole; a door lock pin passing through the door The lock pin hole advances to the outside of the housing or retreats to the inside of the housing; the driving part is used to advance or retreat the door lock pin. In addition, the drive part includes: a drive motor for rotating the drive shaft; an input gear which is a spur gear and which is combined with the drive shaft and rotates; an output gear which is rotated by the input gear; The rotational force of the gear is transmitted to the output gear; the intermediate plate, which rotatably supports the connecting gear member and the output gear, is fixed to the housing in a manner perpendicular to the bottom wall of the housing. The connecting gear member and the output gear are rotatably supported by the intermediate plate such that it has a rotation axis parallel to the bottom wall of the case.

However, some models with heating or models with larger capacity need to be equipped with door locks. During the dehydration and heating process, the door locks need to be locked so that the user cannot open the upper cover of the washing machine, thereby ensuring user safety. At present, the machine cover door lock of the washing machine is mainly an automatic door lock device, which is mainly composed of an electromagnet or a bimetallic sheet, a slide block, a door latch and the like. However, due to the large size of the electromagnet door lock, and mainly relying on slide rails for positioning, the reliability is insufficient; while the bimetal door lock has a delay in opening the door, cannot be opened or closed quickly, and is a power consumption type. That is to say, the bimetal door lock consumes energy continuously during the working process. After abnormal power failure, the lock will be automatically unlocked, and there will be a sound when the door lock operates.
