Embodiment 1

[0072] Embodiment 1 - slider mode:

[0073] In this embodiment, the slider mechanism is provided with a distal slope at the distal end, and the angle between the direction of the slope and the side of the upper cover 200 is an obtuse angle.

[0074] There is an elastic mechanism at the far end of the slider mechanism, that is, the spring is offset, and a force is generated on the slider mechanism to move the upper cover 200. When the upper cover 200 does not fall off, the upper cover 200 resists the movement of the slider mechanism. Next, the outer door pin 330 is not on the slope. When the upper cover 200 falls off, the slider moves toward the upper cover 200, the slope moves to the bottom of the outer door pin 330, and the outer door pin 330 is lifted up, so that the outer door pin 330 Touch the top of the circuit switch.

[0075] Specifically, such as figure 1 As shown, in the initial position, the upper cover 200 remains on the assembly body, the slider structure is unde...

Embodiment 2

[0077] Embodiment 2 - the normal door opening and closing function is on the locking slider:

[0078] In this embodiment, the slider mechanism no longer only detects whether the upper cover 200 falls off. In general, if the slider mechanism only has a function of detecting the falling of the upper cover 200, the overall structure of the lock will increase a lot, and while the cost will increase, for the applicable products, it will be necessary to completely overthrow and reinstall the lock. Production has a lot of negative effects on quantitative production.

[0079] Therefore, the slider mechanism adds the door lock state, and the detection of the door lock state is also the content of the prior art.

[0080] In this example, if figure 2 , the slider mechanism is provided with two slopes, and the two slopes are arranged opposite to each other, similar to the structure of the hull, which are respectively recorded as the distal slope and the proximal slope.

[0081] When i...

Embodiment 3

[0082] Embodiment 3 - normal door opening and closing function is on the door slider:

[0083] In this embodiment, the slider mechanism adds the state of the door lock, and the detection of the state of the door lock is also the content of the prior art.

[0084] In this embodiment, two slopes are provided on the slider mechanism, and the two slopes are arranged opposite to each other, similar to the structure of a ship hull, which are respectively recorded as a distal slope and a proximal slope.

[0085] Different from Example 2, such as image 3 and 4 , the slider mechanism is matched with the cam structure 500. When this embodiment is in use, the slider mechanism is still resisted by the upper cover 200, but a part of the proximal bottom of the slider mechanism still extends into the lock structure. And the proximal end is suspended in the air, and cooperates with the door hook 600. The contact surface between the outer door pin 330 and the slider mechanism adopts an incl...

Abstract

The invention discloses a door lock, which comprises a shell, a locking module, an upper cover and a lock module; the lock module is of a cam structure; the cam structure is matched with a door hook;the door lock with an upper cover state detection function further comprises a sliding block mechanism positioned between the shell and the locking module, wherein the free end of the sliding block mechanism is matched with the upper cover or the lock module; and an outer door bolt, wherein one end of the outer door bolt slides on the sliding block mechanism, and the other end of the outer door bolt is matched with a circuit switch on the locking module. A track platform mechanism is arranged on the sliding block mechanism; when the outer door bolt moves vertically, the top of the outer door bolt touches the circuit switch to change the state of the circuit in the locking module; the upper cover abuts against the sliding block mechanism, and the elastic mechanism keeps a compressed state all the time. In the embodiment of the invention, the internal structure design helps arrive at the function of detecting the falling of the upper cover of the door lock, so that the safety of the washing machine is improved, and errors are reported in time.

Description

technical field [0001] The present application relates to the technical field of door locks, in particular to a door lock with a cover state detection function. Background technique [0002] At present, the door locks of some drum washing machines have the phenomenon that the parts of the upper cover fall off. When this phenomenon occurs, after the upper cover falls off abnormally, close the front door of the washing machine. washing program. In this case, the washing machine will not report an error, and the front door can be opened during operation. At this time, it is necessary to detect the detachment of the upper cover parts. If the upper cover is found to be detached, an error will be reported immediately and the washing process will be stopped to prevent safety accidents. Contents of the invention [0003] In order to solve the above technical problems, this application provides a door lock with a cover state detection function. Through the internal structure desig...
