In addition, the devices of the washing machine main body 1, which may be associated with the locking of the door 2, are switched by the contacts of the load terminal 70 to a state that can be controlled by the controller not shown.

After the washing is completed and the driving voltage applied to the electromagnet 40 is short-circuited, the locking block 30 is returned by the elastic force of the movable terminal 72 of the load terminal 70 as shown in FIG. And the locking block 30 is accommodated in the escape foam. In addition, devices not shown in conjunction with the short circuit of the movable terminal 72 in the fixed terminal 71 of the load terminal 70 is controlled together.

After the door 2 is opened, the hook 3 of the door 2 is opened while being guided by the insertion hole 4 or the locking jaw 56. And the slider 20 returns to its original position by the restoring force of the elastic member 21 acting on the engaging portion 22.

Although the technical idea of the door lock and the door lock switch for a washing machine of the present invention has been described with the accompanying drawings, this is for illustrative purposes only and not for limiting the present invention.

Therefore, it is obvious that any person skilled in the art can make various modifications and imitations such as dimensions, shapes, structures, etc. without departing from the scope of the technical idea of the present invention.

As described above, the door lock and door lock switch for a washing machine of the present invention can control the opening and closing of the door and the locking / unlocking in the washing machine, thereby preventing it from being forcibly opened during driving, thereby preventing safety accidents. There is an effect that can be prevented.

In addition, since the locking / un-locking of the door is controlled by the electromagnet, the reaction speed is very fast and the productivity is simplified by simplifying the structure.
