[0037] Referring to Figure 2 , Figure 3 , Figures 5-7 As shown in the figure, the lock catch assembly 2 comprises a lock catch support 20, two lock catch pieces 21 and two springs one 22, the two lock catch pieces 21 are slidably connected in the lock catch support 20 along the left and right anti-skid directions of the dishwasher, and the two springs one 22 are elastically applied to the two lock catch pieces 21 respectively, and elastically drive the two lock catch pieces 21 to have a mutual approaching tendency.

[0038] A locking gap 211 is formed between the two lock catch pieces 21, and the locking gap 211 is matched with the lock tongue part 111, and the lock tongue part 111 can be embedded in the locking gap 211 and locked with the two lock catch pieces 21. In order to facilitate the locking of the lock tongue part 111 and the lock catch piece 21, a guide surface can be formed at the pressing contact position of the lock tongue part 111 and the lock catch piece 21, and during the extension of the lock tongue part 111 between the two lock catch pieces 21, the two lock catch pieces 21 can be pushed to slide away from each other to the left and right sides until the lock tongue part 111 is positioned. The two springs one 22 can push the two lock catch pieces 21 to approach each other to elastically lock the lock tongue part 111.

[0039] The lock catch assembly 2 further comprises a linkage block 23 and an inductor three 25, the linkage block 23 is located at the lower side of the two lock catch pieces 21, and part of the linkage block 23 extends upward into the locking gap 211 between the two lock catch pieces 21. The door body 4 of the dishwasher comprises a mounting frame 41, the mounting frame 41 is fixedly connected with a sliding frame 411, and the lower side of the linkage block 23 is slidably connected to the sliding frame 411. Through the sliding guidance of the sliding frame 411, the linkage block 23 can move along the front and rear directions of the dishwasher relative to the lock catch support 20.

[0040] The upper side of the linkage block 23 can extend into the locking gap 211 between the two locking pieces 21. The locking tongue 111 is fixedly connected with a protrusion 115 on the lower side, and the position of the protrusion 115 is matched with the position of the linkage block 23. When the locking tongue 111 extends into the locking gap 211, the protrusion 115 abuts against the linkage block 23. When the locking tongue 111 is locked in the locking assembly 2, the linkage block 23 can push the linkage lever 24, so that the linkage lever 24 can trigger the sensor three 25.

[0041] In addition, the locking assembly 2 further comprises a linkage lever 24 and a spring two 26. The linkage lever 24 is slidingly connected to the locking bracket 20 along the left-right direction of the dishwasher, and a left-right sliding groove is formed in the linkage lever 24. The sliding groove is matched with the sliding block of the locking bracket 20, so as to guide the sliding of the linkage lever 24.

[0042] A linkage inclined surface 241 is formed on the side of the linkage lever 24 facing the linkage block 23. The linkage block 23 can abut against the linkage inclined surface 241. The side of the linkage lever 24 away from the linkage block 23 can trigger the sensor three 25. When the locking tongue 111 is inserted into the locking assembly 2, the protrusion 115 on the lower side of the locking tongue 111 can push the linkage block 23 after being inserted to a certain depth. Then, the linkage block 23 abuts against the sensing position of the sensor three 25, so as to trigger the sensor three 25 and send a signal indicating that the door body is locked.

[0043] The spring two 26 elastically acts on the linkage lever 24 and has an elastic tendency towards the linkage block 23. The spring two 26 can be a tension spring. The locking bracket 20 is fixedly connected with a connecting portion one 261, and the linkage lever 24 is fixedly connected with a connecting portion two 262. The two ends of the spring two 26 are connected with the connecting portion one 261 and the connecting portion two 262 respectively, so as to apply an elastic restoring force to the linkage lever 24. After the locking tongue 111 is separated from the locking assembly 1, the spring two 26 elastically pushes the linkage lever 24 and the linkage block 23 to reset, so as to no longer trigger the sensor three 25 and indicate that the door body 4 is in an open state.

[0044] When the door body 4 of the dishwasher is closed, the telescopic rod 11 of the locking assembly 1 is in a retracted state. The locking tongue 111 is clamped into the locking assembly 2, and the locking tongue 111 is clamped between the two locking pieces 21 against the spring one 22. The spring one 22 pushes the locking pieces 21 to close, so as to clamp and lock the locking tongue 111. At the same time, the protrusion 115 on the lower side of the locking tongue 111 can push the linkage block 23 of the locking assembly 2. The linkage block 23 and the linkage lever 24 are linked to each other, so as to trigger the sensor three 25 and send a signal indicating that the door body 4 of the dishwasher is closed.

[0045] When the door body 4 of the dishwasher is opened, the lock tongue assembly 1 is away from the lock tongue part 111, the lock tongue part 111 is separated from the two lock catch parts 21, the lock catch parts 21 are expanded outward against the spring 22, until the lock tongue part 111 is pulled out; at the same time, the spring 26 resets the elastic pushing linkage rod 24 and the linkage block 23, and the inductor 3 is no longer triggered, indicating that the door body 4 is in an open state.

[0046] When the door body 4 is closed, that is, the lock tongue part 111 is in the locked state with the lock catch assembly 2, the forward extension of the telescopic rod 11 can push the door body 4 to move in the forward direction, that is, the door body 4 can be opened, at this time, the lock tongue part 111 is still in the locked state with the lock catch assembly 2; the telescopic rod 11 is retracted backward, which can drive the door body 4 to move in the closing direction, that is, the door body 4 can be closed, at this time, the lock tongue part 111 is still in the locked state with the lock catch assembly 2, and the elastic locking structure between the lock tongue part 111 and the lock catch part 21 is used for transmission.

[0047] In the process of automatic opening and closing of the door body 4, if the door body 4 is manually pulled open, at this time, the inductor 2 142 will stop triggering, and can send a signal to the controller of the dishwasher that the door body 4 of the dishwasher is opened; at this time, the telescopic rod 11 is retracted by the preset program control lock tongue assembly 1, and the telescopic rod 11 is retracted to the innermost end until the sensing part 1 113 triggers the sensing signal with the inductor 1 141, and is retracted to the predetermined position.

[0048] In this embodiment, the telescopic stroke of the telescopic rod 11 is greater than 5 cm, and generally can be 10 cm, for example, 8 cm. The telescopic rod 11 is pushed out to the front side of the dishwasher, which can push the door body 4 to open to a larger angle.

[0049] In the process of opening the door body 4 of the dishwasher, the door body 4 will be rotated from the original vertical state to the inclined state. When the opening amplitude of the door body 4 is small, the lock catch assembly 2 on the upper side of the door body 4 moves in the tangential direction, and the height of the lock catch assembly 2 basically does not change.

[0050] When the opening amplitude of the door body 4 is large, generally more than 5 cm, the height of the upper edge of the door body 4 will change obviously, that is, the height position of the lock catch assembly 2 will change. The lock tongue part 111 of the telescopic rod 11 may interfere with the lock catch assembly 2, which may cause the lock catch assembly 2 and the lock tongue part 111 to be stuck, affecting the normal opening and closing of the door body 4.

[0051] Referring to Figure 8 As shown in the figure, the telescopic rod 11 is slidingly connected in the housing 10, and a guide rib and a guide groove that are matched with each other are arranged between the inner wall of the housing 10 and the telescopic rod 11, which can guide the telescopic direction of the telescopic rod 11, and ensure that the telescopic rod 11 can stably slide according to the sliding track.

[0052] The sliding direction of the telescopic rod 11 is along the front-rear direction of the dishwasher, and is inclined downward toward the front end direction. When the telescopic rod 11 is extended forward, the lock tongue part 111 at the front end of the telescopic rod 11 will also have an adaptive height change, so that the lock tongue part 111 can always stably be clamped between the two lock catch pieces 21 of the lock catch assembly 2, maintaining the state of elastic locking.

[0053] In the embodiment, the telescopic rod 11 is inclined downward toward the front end direction at an angle of 3-8°.

[0054] Moreover, the locking gap 211 of the two lock catch pieces 21 has a height in the up-down direction greater than that of the lock tongue part 111, and the upper side of the locking gap 211 is substantially open, being limited only by the position of the lock hole of the door body 4. The lock tongue part 111 can move up and down within the locking gap 211, and through adaptive adjustment of the lock tongue part 111, it can be ensured that the lock tongue part 111 can stably be in the state of locking, maintaining the stable elastic locking of the lock tongue part 111 and the two lock catch pieces 21.

[0055] Since the linkage block 23 is located at the lower side of the two lock catch pieces 21, during the opening of the door body 4, the upper edge of the door body 4 will be slightly displaced downward, and the lock catch assembly 2 and the internal linkage block 23 will also be displaced downward. During the opening of the door body 4, the linkage block 23 will not interfere with the lock tongue part 111 on the upper side of the protrusion 115, and it can be ensured that the protrusion 115 at the lower side of the lock tongue part 111 can stably be in the state of abutting against the linkage block 23, ensuring that the inductor three 25 can be stably triggered.

[0056] The embodiment also discloses a dishwasher, referring to Figure 1 As shown in the figure, comprising a cabinet 3, a door body 4, and a door lock assembly as in the above embodiment, the lock tongue assembly 1 is installed on the top of the cabinet 3, the lock catch assembly 2 is installed in the upper edge of the door body 4, and the lower side of the door body 4 is hinged to the cabinet 3. Through the door lock assembly, the door body 4 can be locked, and the automatic opening and closing action of the door body 4 can be realized.

[0057] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above embodiment. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application shall also be considered as falling within the protection scope of the present application.
