[0026] In this embodiment, a slide plate 3 is provided at the rear edge of the door body 2, which can move forwards and backwards with the door opening and closing actions. When closing the door, the slide plate 3 moves backwards with the door closing action, and covers the gap 12 in the closed state to prevent debris from entering and bacteria from breeding; when opening the door, the slide plate 3 moves forward with the opening process of the door body 2 to form an anti-interference structure for door opening, thereby avoiding interference between the door body 2, the slide plate 3 and the sink groove 12, greatly improving the user experience.

[0027] A convex sleeve 21 extending in the length direction is partially provided on the rear side wall of the door body 2, and a connecting assembly 4 for rotatably connecting the door body 2 to the sink groove 12 is installed in the convex sleeve 21. The slide plate 3 can be constrained on the rear side of the convex sleeve 21 so as to move forward and backward, and a baffle 31 covering the upper surface of the door body 2 and moving forward and backward with the slide plate 3 is formed on the top of the slide plate 3. With the above structure, the slide plate 3 is constrained on the rear side of the convex sleeve 21 and matched with the outer periphery of the convex sleeve 21. In the process of the slide plate 3 moving forward and backward, the outer surface of the convex sleeve 21 will provide a guide for the movement of the slide plate 3 with the opening and closing action of the door body 2, so that the movement of the slide plate 3 and the door opening and closing action are precisely matched, the assembly stability of the slide plate 3 is maintained, and it is ensured that the gap 12 is covered in the closed state, and the slide plate 3 will not interfere with the sink groove 11 in the process of opening the door.

[0028] In the closed state, the baffle 31 moves backward with the slide plate 3 to form a shielding structure; in the door opening process, the baffle 31 moves forward with the slide plate 3 to form an anti-interference structure. This structure can ensure that the gap 12 is covered in the closed state, and the slide plate will not interfere with the sink groove in the door opening process.

[0029] The slide plate 3 is hollow inside and can be moved forward and backward to cover the outer periphery of the convex sleeve 21, and the spring 5 is arranged between the rear side wall of the slide plate 3 and the convex sleeve 21. With such a structure, it is convenient for the slide plate 3 to perform adaptive adjustment to the opening and closing action of the door body 2, so that the gap 12 is covered in the closed state, and the slide plate 3 will not interfere with the sink groove 12 during the door opening process.

[0030] Specifically, the convex shaft sleeve 21 is provided with an assembly hole 211 extending from the rear to the front, and the inner side of the rear side wall of the slide plate 3 is provided with a limit sleeve 32 extending forward and guiding and cooperating with the assembly hole 211 to limit the position, and the spring 5 is elastically compressed in the assembly hole 211 and the limit sleeve 32. With the above structure, it is easy to install the spring 5, so that the slide plate 3 can always be stably driven to move forward and backward.

[0031] In this embodiment, the cross section of the slide plate 3 includes a horizontal portion 33 corresponding to the baffle plate 31, a vertical portion 34 extending downward from the rear edge of the baffle plate 33, and an arc portion 35 extending downward and forward from the lower edge of the vertical portion 34; in the closed state, the vertical portion 34 is arranged close to the rear side wall of the sinking platform groove 12, and the connection between the vertical portion 34 and the arc portion 35 is arranged corresponding to the middle of the rear side wall of the sinking platform groove 11, and the horizontal portion 33 covers the top of the convex sleeve 21 and covers the gap 12 at the rear; in the open state, the vertical portion 34 is horizontally against the bottom surface of the sinking platform groove 12, the horizontal portion 33 is arranged vertically and has a spacing with the rear side wall of the sinking platform groove 11, and the arc portion 35 contacts and cooperates with the outer surface of the bottom of the convex sleeve 21. With the above structure, in the process of the slide plate 3 moving forward and backward, the outer surface of the convex sleeve 21 will provide a guiding effect for the movement of the slide plate 3 as the door body 2 opens and closes, so that the movement of the slide plate 3 and the door opening and closing actions are precisely matched, and the assembly stability of the slide plate 3 is maintained. Moreover, when the door is open, the vertical portion 34 rests horizontally against the bottom surface of the sink groove 11, so that the door body 2 can be placed vertically, and the door body 2 is prevented from being opened at an angle exceeding 90 degrees and abutting against the upper edge of the sink groove 11, causing indentations or damage to the surface of the door body 2 in the long run.

[0032] The front end of the horizontal portion 33 of this embodiment is provided with a first limiting portion 331 capable of limiting the horizontal portion 33 with the top of the convex sleeve 21, and the lower end of the arc portion 35 is provided with a second limiting portion 351 capable of limiting the horizontal portion 33 with the bottom of the convex sleeve 21. This structure is conducive to improving the assembly stability of the slide plate 3 on the convex sleeve 21, so that it can be adaptively adjusted with the door opening and closing actions, but always maintains reliable restraint.

[0033] Specifically, the top of the convex sleeve 21 is formed with a plane 212 that guides and cooperates with the baffle 31 in the horizontal direction, the first limiting portion 331 is a first convex rib extending forward from the front edge of the horizontal portion 33, the lower surface of the first convex rib forms a first arc surface 332 that can guide and cooperate with the arc portion 35 of the convex sleeve 21 located in front of the plane 212, and a clearance groove 213 for the first convex rib to move forward and backward is formed between the front edge of the top of the convex sleeve 21 and the upper surface of the door body 2. With the above structure, it is convenient to limit the connection between the top of the slide plate 3 and the door body 2, and improve the installation reliability of the slide plate 3. The second limiting portion 351 is a second convex rib extending forward from the lower edge of the arc portion 35, and the upper surface of the second convex rib forms a second arc surface 352 that can guide and cooperate with the arc portion 35 at the bottom of the convex sleeve 21. With the above structure, it is convenient to limit the connection between the bottom of the slide plate 3 and the door body 2, and improve the installation reliability of the slide plate 3.

[0034] The convex sleeve 21 is partially missing in its axial direction to form an installation opening 214, and the installation opening 214 corresponds to the sinking groove 11 and the convex sleeve 21. The connecting component 4 is a hinge in this embodiment. This structure facilitates the door body 2 to be compactly and stably constrained in the sinking groove 11.

[0035] When the door is opened, the rear side wall of the slide plate 3 slides with the rear side wall and the bottom wall of the sink groove 11, and the sink groove 11 applies an overall forward force to the slide plate 3, thereby overcoming the force of the spring 5 and moving the slide plate 3 forward, avoiding interference between the slide plate 3 and the sink groove 11 and affecting the door opening action; when the door is fully opened, the rear side wall of the slide plate 3 abuts against the bottom plane of the sink groove 11, and the door body 2 is flipped 90 degrees relative to the horizontal plane and is stably supported on the bottom plane of the sink groove 11 by the slide plate 3.
