In this embodiment, the cleaning machine performs the cleaning state only when both the microswitches are in the triggered state.

The elastic force of the second spring 02 between the ejector 6 and the sliding rod 71 is limited, when no external force is received, the second spring 02 can eject the ejector 6 to the maximum position, and when external force is applied (such as the self weight of the electric appliance door body 2), the elastic force of the second spring 02 cannot support the ejector 6, and the second spring 02 is compressed to the position where the first extending portion 611 of the ejector 6 contacts with the second extending portion 711 of the sliding rod 71. The initial spring force of the first spring 01 is far greater than the mounting initial elastic force of the second spring 02, and only when the initial spring force is greater than the self-gravity of the electric appliance door body 2, the sliding part 9 moves downwards to compress the first spring 01.

The working process of the cleaning machine is as follows:

as shown in fig. 2 and 3, in the initial state of the door opening of the washing machine, the contact of the position switch 032 is pressed by the second protrusion 814 on the moving member 81 to be in the activated state, and both the magnetic switch and the door-locking switch 031 are in the off state. When the electric appliance door body 2 is naturally placed, a certain downward pressure is exerted on the lock body 5 due to the self weight of the electric appliance door body 2, namely, the lock rod 4 has downward pressure on the ejecting piece 6, and the lock rod 4 and the ejecting piece 6 move downwards together due to the fact that the elastic force of the second spring 02 is smaller than the force of the lock rod 4 on the ejecting piece 6. Only the ejector 6 moves downwards at this time, and the sliding rod 71 does not move downwards due to the elastic force of the first spring 01 to the sliding member 9 and the sliding block 72 until the ejector 6 moves downwards until the first extension 61 of the ejector contacts the second extension 711 of the sliding rod 71, as shown in fig. 4 to 6. At this point, the magnetic member on the ejector 6 is in close proximity to the magnetic switch, and the signal to the magnetic switch is on, giving a command to the motor 82 to tell that the locking bar 4 has entered through the opening 301 into the chamber 30.

When the door needs to be automatically closed, the motor 82 receives a signal that the lock rod 4 enters the chamber 30, the motor 82 works, and drives the moving member 81 to move downward through the transmission of the driving gear 83 and the transmission gear 84, when the moving member 81 moves downward until the first flange of the moving member abuts against the second flange of the sliding block 72, when the moving member 81 continues to move downward, the sliding block 72 and the sliding rod 71 (i.e., the movable assembly 7) are driven to move downward together, then the movable assembly 7 drives the ejector 6 to move downward together, in the downward movement process of the ejector 6, the lock body 5 is driven to rotate counterclockwise, in the rotation process of the lock body 5, the upper end of the lock body 5 contacts with the hook portion 41 of the lock rod 4, the upper end of the lock body 5 pulls the hook portion 41 of the lock rod 4 to move downward, and along with the continuous downward movement of the ejector 6, the torsion spring 05 on the lock body 5 generates counterclockwise force which is changed from clockwise to counterclockwise to the lock body 5, which is more beneficial for the lock body 5 to pull the lock rod 4 downward until the lock rod 4 is pulled to the bottom, and at this time, the lock portion 51 and the lock body 41 are in a locked state. Thus, the automatic door closing is realized, and as shown in fig. 8 in particular, at this time, the three protrusions on the moving member are all located below the position switch, and at this time, the position switch is in an off state, and the door locking switch is pressed by the sliding block 72 and is in a trigger state. Subsequently, the motor 82 drives the moving member 81 to move upward until the uppermost protruding portion 814 abuts against the contact of the position switch 031, so as to trigger the position switch 031, and the cleaning machine can be in a cleaning state.

When the door needs to be closed manually, after a user applies downward pressing force to the electric appliance door body 2, the lock rod 4 pushes the ejector 6 downwards, and at the moment, the lock body 5 is driven to rotate anticlockwise to be locked with the hook portion 41 on the lock rod 4. When the ejector 6 moves downwards, the ejector 6 drives the movable assembly 7 to move downwards, at this time, the movable assembly 7 presses the sliding piece 9 downwards, so that the sliding piece 9 moves downwards, when the sliding piece 9 moves downwards, the first spring 01 is extruded, the first spring 01 is compressed to generate certain upward thrust, but because the torsion spring 05 on the lock body 5 can apply downward torsion to the lock body 5, the torsion is larger than the upward thrust of the first spring 01 at this time, the locking state of the lock body 5 and the lock rod 4 can be maintained, and after the force application of a user is cancelled, the ejector 6 cannot rebound upwards, so that the manual door closing is realized, and particularly, as shown in fig. 7, the manual door closing is realized; in this state, the sliding block 72 presses the contact of the door locking switch 031, so that the door locking switch 031 is in a conducting state, and the cleaning machine can be in a cleaning state.
