The present invention relates to a door lock for a cleaning machine and a cleaning machine. The door lock comprises a lock groove, a locking member and a pushing block. The present invention sets the force and force matching surfaces in the door closing process as two groups staggered front and back. The first guide surface and the second guide surface located on the rear side are used to push the locking member to flip forward after the door is closed. The third guide surface and the fourth guide surface located on the front side are used to limit the position of the locking member in the door open state. Since the rotational torque of the friction force corresponding to the third guide surface is greatly reduced, the force to be overcome in the door closing process is correspondingly reduced, which has the effect of saving effort in closing the door. After the door is closed, the rotational torque of the friction force corresponding to the first guide surface is relatively large, and a relatively large forward flipping force can still be applied to the locking member, so that the locking member can grip the lock groove, maintain a relatively large gripping force on the door body, and improve the sealing of the door body.

The door lock of this embodiment is used:
As shown in fig. 8, in the door-open state, the third guide surface 303 and the fourth guide surface 304 of the locking member 32 abut against and friction-limit, so as to prevent the locking member 32 from rotating anticlockwise;
When the door is closed, the locking piece 32 needs to be rotated anticlockwise, the locking piece 32 is pushed by the trigger component 34, at this time, the third guide surface 303 of the locking piece 32 is in contact with the fourth guide surface 304 of the pushing block 331, and the first guide surface 301 is not in contact with the second guide surface 302, because the third guide surface 303 of the locking piece 2 is an arc surface taking the rotating shaft of the locking piece 32 as the center, the thrust force F pushing the movable block 331 is 0 to the rotating force arm of the locking piece 32, the thrust force F does not have rotating moment to the locking piece 32, the thrust force F can generate friction force when the third guide surface 303 and the fourth guide surface 304 slide relatively, namely, the door is required to overcome the rotating moment generated by the friction force F1 to the locking piece 32, and because the L1 is reduced, the rotating moment of the friction force is reduced, the door closing force is reduced, and labor is saved;
when the locking piece 32 rotates anticlockwise against the friction rotation moment under the action of the door closing force and passes through the turning point shown in fig. 9, the force arm between the thrust force F of the locking piece 32 and the rotation center of the locking piece 32 gradually becomes larger from 0, so that anticlockwise rotation moment is formed, and the locking piece 32 is pushed to rotate anticlockwise;
As shown in fig. 10, the force pushing the locking member 32 to rotate counterclockwise is the guiding inclined plane 305, and the force bearing surface between the locking member 32 and the pushing block 331 gradually changes from the engagement of the third guiding surface 303 and the fourth guiding surface 304 to the engagement of the first guiding surface 301 and the second guiding surface 302;
as shown in fig. 11, after the door is closed, the lower end of the first guiding surface 301 of the locking member 32 is in press fit with the second guiding surface 302, and the pushing force F of the pushing block 331 and the long arm formed by the center of the rotating shaft of the locking member 32 maintain a large door locking force.
