Door lock and top-loading washer

Abstract

A door lock comprises an electromagnet, a bolt shaft, a crank device and the like, wherein the crank device is connected with the bolt shaft and driven by the electromagnet, and rectilinear motion of the electromagnet is converted into rotational motion of the bolt shaft. When the electromagnet pushes or pulls the crank device, a bolt head is enabled to rotate around an axis, so that the bolt head moves to a lock position or release position. According to the door lock, the rectilinear motion of the electromagnet can be converted into rotational motion of the bolt head, so that the bolt head is conveniently mounted on the side surface instead of an end of the door lock, and accordingly, the door lock can be mounted in a middle gap of a control panel along the edge of the control panel of a washer, and an upper cover is locked from the middle.

Description

technical field [0001] The invention relates to a door lock for electrical equipment, in particular to a door lock applied to a cover-type washing machine. Background technique [0002] When the drum of the top-cover type (straight-through type) washing machine rotates at a high speed (such as a spin-drying operation), the top cover needs to be locked for safety to prevent accidental opening. [0003] The door lock 106 that is installed on this washing machine at present is as Figure 1A As shown, one side of the upper cover 101 of the upper cover washing machine 100 is movably fixed on the upper part of the washing machine 100 through a hinge 103 , and the right end 105 of the other side is fixed through a door lock 106 . Washing machine 100 front panel 102 width is limited, and middle part needs to install display screen, PCB control panel etc., and the space width that remaining can be installed door lock 106 is extremely small, only has 10-20mm, but linear electromagneti...

AI Technical Summary

Problems solved by technology

This approach will result in Figure 1A The problem shown: Since the handle is in the center, when the upper cover is pulled up in the locked state, one side of the upper cover 101 is locked, but the other side will be tilted or can still be partially opened, and the closing effect is not good

But due to the length limitation when the linear electromagnetic door lock 106 is installed, as Figure 1B As shown, it can only be arranged along the edge direction of the front panel 102 (horizontally arranged), but the lock head of the existing linear electromagnetic door lock 106 is stretchable along the length direction, so this problem cannot be solved
