The above structure facilitates the installation of the lock block 61 that is movable upward and downward, and the structure is compact and stable.

[0033] In the embodiment, the limiting assembly 3 is arranged between the side part of the door body 2 and the side part of the door frame 1. The limiting assembly 3 comprises a first part arranged in the middle part of the outer side wall of the door body 2 and a second part arranged in the middle part of the inner side wall of the door frame 1, and in the closed state, the first part is limited in cooperation with the second part, and in the open state, the first part is relatively separated from the second part.

[0034] Specifically, the door frame 1 is provided with a containing groove 11 extending from the front side wall to the back, and the containing groove 11 is provided with a first limiting piece 31 capable of moving towards or away from the door body 2. Correspondingly, the outer side wall of the door body 2 is provided with a second limiting piece 32, and the first limiting piece 31 and the second limiting piece 32 are detachably matched for limiting. The detachable matching structure of the first limiting piece 31 and the second limiting piece 32 can facilitate the realization of door closing limiting and automatic avoidance when opening the door.

[0035] The first limiting piece 31 is a limiting column capable of reciprocating relative to the door body 2, and the limiting column always has a tendency to move towards the door body 2. The middle part of the second limiting piece 32 is provided with a limiting groove 321 extending vertically and capable of accommodating the limiting column, and the front side wall and the back side wall of the second limiting piece 32 are smoothly connected with the limiting groove. The limiting groove 321 and the smoothly connected part form a structure with a cross section in the shape of 3. The above structure can make the limiting reliable in the door closing state, smooth and labor-saving in the door opening process, and convenient to operate.

[0036] The top and bottom of the limiting column are respectively provided with a limiting block 311, the door frame 1 is provided with a sliding groove 12 extending along the moving direction of the limiting column, the limiting block 311 is slidingly constrained in the sliding groove 12, and the sliding groove 12 is provided with an elastic piece 332 for driving the limiting block 311 to move towards the door body 2. The limiting column, the limiting block 311 and the elastic piece 332 jointly constitute a second part, and the second limiting piece 32 constitutes a first part. The above structure can improve the reliability of the second part limiting the first part and the stability between the state switching of the second part in the door opening and closing process.

[0037] The sliding groove 12 is provided with a guide column 13 extending along the moving direction of the limiting column, the limiting block 311 is slidingly connected to the guide column 13, and the elastic piece 332 is sleeved on the outer periphery of the guide column 13 and is elastically compressed in the sliding groove 12 outside the limiting block 311. The structure is conducive to further improving the moving stability of the second part.

[0038] The inner side of the door body 2 is provided with a protruding rib 21 arranged close to the edge, and the outer periphery of the protruding rib 21 is provided with a sealing ring 22. In the door closing state, the sealing ring 22 is respectively extruded and sealed with the protruding rib 21 and the inner side wall of the door frame 1. The above structure can improve the sealing reliability between the door body and the door frame.

[0039] The front side wall of the machine body 5 has a notch groove 52 starting close to the sealing ring 22. In the door closing state, the back surface of the protruding rib 21, the back surface of the sealing ring 22 and the back surface of the door frame 1 are aligned, and the notch groove 52 constitutes a buffer zone outside the sealing ring 22. In the cleaning process, the water hitting the inner side wall of the door body 2 is easy to accumulate at the edge when falling. The above structure makes the accumulated water flow down through the buffer zone across the sealing ring 22, so as to prevent the accumulated water from accumulating too much at the sealing ring 22 and causing water leakage problem.

[0040] The inner side wall of the door body 2 inside the convex rib 21 forms a flow guide surface 231 arched outward from the upper and lower edges to the middle. This structure can guide the water hitting the inner surface of the door body 2 downward in time, avoiding serious water hanging on the inner wall of the door body. The convex rib 21 inside the door body 2 is embedded with a door inner plate 23, and the flow guide surface 231 is formed on the door inner plate 23. The door inner plate 23 can be made of a material with good sound insulation and good water repellency, to further avoid water hanging on the inner surface of the door body and reduce noise.

[0041] In the embodiment, the door body assembly A is provided as the door frame 1 connected with the machine body 5 and the door body 2 reversibly arranged in the door frame 1. The cooperation between the door body 2 and the door frame 1 is more compact. In the closed state, the top of the door body 2 and the top of the door frame 1 can still be locked by the door lock structure, and the middle of the door frame 1 and the middle of the door body 2 are limited, which is beneficial to improve the reliability of the door body sealing, and the limiting structure does not affect the opening operation when the door is opened, and is convenient to use.

[0042] In the description and claims of the present application, terms used for indicating directions, such as "front", "back", "up", "down", "left", "right", "side", "top", "bottom", etc. are used to describe various example structural parts and elements of the present application, but these terms are only used for the purpose of convenient description and are determined based on the example orientation shown in the drawings. Since the disclosed embodiments of the present application can be arranged in different directions, these terms indicating directions are only used for description and should not be considered as limitation, for example, "up" and "down" are not necessarily limited to the direction opposite or consistent with the direction of gravity.
