[0002] For a sink-type dishwasher, its door assembly is generally rotatably connected to the rear edge of the top opening of the sink, so as to facilitate opening and closing and taking and placing dishes. The Chinese utility model patent "A door assembly of a sink-type washing machine and a washing machine" (application number: CN202122484955.7) with authorization announcement number CN216535216U discloses a structure, which includes: a main door panel, having a relative top surface and a bottom surface; a muffler, arranged on the main door panel; a bottom plate, arranged on the bottom surface of the main door panel, the top surface of the bottom plate is opposite to the bottom surface of the main door panel and a gap is left between the two; a vibration-damping pad, arranged in the gap, and the bottom surface of the vibration-damping pad is in contact with the top surface of the bottom plate, and the top surface of the vibration-damping pad is in contact with the bottom surface of the main door panel.

[0003] The lower surface of the door of the above-mentioned existing sink dishwasher is usually horizontal. During the cleaning process, the water jets spraying upwards will continuously hit the lower surface of the door, causing serious water droplets to adhere to the lower surface of the door. When the door is opened, the water droplets on the lower surface of the door are easy to drip near the hinge on the rear side of the dishwasher, which is difficult to clean and affects the user experience. Although many dishwashers are equipped with a drying structure in the cabinet, it is difficult to effectively dry the lower surface of the door away from the cabinet due to the slow flow of gas at the door. Utility Model Content

[0004] The first technical problem to be solved by the utility model is to provide a door assembly of a cleaning machine that can prevent water droplets from adhering to the lower surface of the door body and converge in a directional manner, thereby improving the user experience, in view of the current status of the prior art.

[0005] The second technical problem to be solved by the utility model is to provide a cleaning machine using the above-mentioned door body assembly in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve at least one of the above technical problems is:

[0007] A door body assembly of a cleaning machine includes an inner plate, the lower surface of the inner plate is formed with a protruding portion that can be buckled into the cleaning machine when the door is closed, the lower surface of the protruding portion is partially sunken to form a first ridge arranged near the front edge and extending laterally, and a second ridge arranged near the rear edge and extending laterally, and the lower surface of the protruding portion gradually tilts downward from the first ridge to the second ridge to form a guide structure.

[0008] The inner wall of the door of the utility model adopts a structure that is high in the front and low in the back. When the door is closed, it is easy for water droplets on the lower surface of the door to slide down, avoiding water hanging on the lower surface of the door. When the door is open, due to the existence of the guide structure, its bottom area sinks into the cavity range of the cleaning machine, which is conducive to the water attached to the lower surface of the door to fall into the inner cavity of the cleaning machine, avoiding problems such as water accumulation in the hinge area of ​​the door, and is conducive to improving user experience. In addition, the first ridge and the second ridge are used to gather water flow, and the water flow is gathered at the bottom of the linear ridge with a small contact area. Compared with a flat surface, it is more difficult for water droplets to adhere. Under the condition of hot air blowing, water droplets are easier to drip, so that the surface of the inner plate is thoroughly dried to achieve an ideal drying effect.

[0009] Preferably, the lower surface of the protruding portion forms a laterally V-shaped confluence structure near the front edge, and the tip of the V-shaped structure constitutes the first convex ridge. With the above structure, water droplets near the front side of the door body can be gathered to the first convex ridge to guide the water droplets into the washing chamber as quickly as possible and reduce the amount of water droplets hanging on the wall.

[0010] Preferably, the area between the first convex ridge and the second convex ridge is divided into a first area, a second area, and a third area arranged side by side, the first area is arranged close to the first side of the inner plate, the third area is arranged close to the second side of the inner plate, the second area is located between the first area and the third area, and the second area is concave upward relative to the first area and the third area. With the above structure, the amount of water splashed by the spray arm is large for the second area in the central part, and the concave structure is conducive to collecting the accumulated water and guiding it in a directional manner.

[0011] Preferably, the inner plate top wall corresponding to the second area gradually tilts downward from front to back to form a first guide slope, the inner plate top wall corresponding to the first area gradually tilts downward from front to back to form a second guide slope, and the inner plate top wall corresponding to the third area gradually tilts downward from front to back to form a third guide slope. The first guide slope, the second guide slope, and the third guide slope together constitute the guide structure. The slope of the first guide slope is greater than the slopes of the second guide slope and the third guide slope. The above structure is used to conduct qualitative guidance for different areas, which is conducive to improving the water guide effect.

[0012] Preferably, the rear edge of the V-shaped structure extends upward into the second area along its inclined direction so that the front edge of the second area is located behind the front edges of the first area and the third area, and the rear edge of the V-shaped structure and the front edge of the first guide slope together form a third convex ridge that arches upward. The third convex ridge is provided to quickly divert and guide the accumulated water to the first convex ridge and the second convex ridge.

[0013] Preferably, the side wall of the first region connected with the second region gradually tilts and extends into the second region from the back to the front to form a fourth guide slope, and the front end of the fourth guide slope is smoothly connected to the rear side wall of the V-shaped structure. The side wall of the third region connected with the second region gradually tilts and extends into the second region from the back to the front to form a fifth guide slope, and the front end of the fifth guide slope is smoothly connected to the rear side wall of the V-shaped structure. The above structure is conducive to improving the guide effect between the first region, the second region, and the third region, and avoiding water accumulation among the three.

[0014] Preferably, the front edge of the first guiding slope, the inner edge of the fourth guiding slope, the inner edge of the fifth guiding slope and the rear edge of the first guiding slope together enclose a trapezoidal structure with a short front end and a long rear end. This structure is conducive to further improving the water guiding effect.

[0015] Preferably, the lower surface of the protruding portion forms a sixth flow guiding slope near the rear edge, which gradually slopes upward from the second convex ridge outward. This structure is conducive to gathering the accumulated water at the rear edge of the door body to the second convex ridge.

[0016] A cleaning machine comprises a water tank with an open top and the above-mentioned door body assembly, wherein a hinge for rotatably connecting the door body assembly to the open rear edge of the water tank top is arranged at the rear edge of the door body assembly.

[0017] Compared with the prior art, the advantages of the utility model are: the inner wall of the door body of the utility model adopts a structure that is high in the front and low in the back. When the door body is in a closed state, it is convenient for water droplets to slide down on the lower surface of the door body, avoiding water hanging on the lower surface of the door body. When the door is open, due to the existence of the guide structure, its bottom area sinks into the cavity range of the cleaning machine, which is conducive to the water attached to the lower surface of the door body falling into the inner cavity of the cleaning machine, avoiding problems such as water accumulation in the hinge area of ​​the door body, and is conducive to improving user experience; in addition, the first ridge and the second ridge are used to converge water flow, and the water flow is converged at the bottom of the linear ridge with a small contact area. Compared with a flat surface, it is more difficult to adhere to water droplets. Under the condition of hot air blowing, water droplets are easier to drip, so that the surface of the inner plate is thoroughly dried to achieve an ideal drying effect.

[0023] like Figures 1 to 4 As shown, the door body assembly of the cleaning machine in this embodiment includes an inner panel 1, and a protruding portion 100 is formed on the lower surface of the inner panel 1, which can be buckled into the cleaning machine in a closed state. The lower surface of the protruding portion 100 is partially sunken to form a first ridge 11 arranged near the front edge and extending laterally, and a second ridge 12 arranged near the rear edge and extending laterally. The lower surface of the protruding portion 100 gradually tilts downward from the first ridge 11 to the second ridge 12 to form a guide structure.

[0024] The lower surface of the protruding portion 100 forms a laterally V-shaped confluence structure 15 near the front edge, and the tip of the V-shaped structure forms a first convex ridge 11. With the above structure, water droplets near the front side of the door body can be gathered at the first convex ridge 11 to guide the water droplets into the washing chamber as quickly as possible and reduce the amount of water droplets hanging on the wall.

[0025] The area between the first convex rib 11 and the second convex rib 12 is divided into a first area a, a second area b, and a third area c arranged side by side, the first area a is arranged close to the first side of the inner plate, the third area c is arranged close to the second side of the inner plate, the second area b is located between the first area a and the third area c, and the second area b is recessed upward relative to the first area a and the third area c. With the above structure, the amount of water splashed by the spray arm is large for the second area b in the central part, and the recessed structure is conducive to collecting the accumulated water and directing it in a directional manner.

[0026] The inner plate top wall corresponding to the second area b gradually tilts downward from front to back to form a first guide slope 10, the inner plate top wall corresponding to the first area a gradually tilts downward from front to back to form a second guide slope 20, and the inner plate top wall corresponding to the third area c gradually tilts downward from front to back to form a third guide slope 30. The first guide slope 10, the second guide slope 20, and the third guide slope 30 together constitute the above-mentioned guide structure. The slope of the first guide slope 10 is greater than the slope of the second guide slope 20 and the third guide slope 30. The above structure is used to conduct qualitative guidance for different areas, which is conducive to improving the water guiding effect.

[0027] The rear edge of the V-shaped structure extends upward into the second area b along its inclined direction so that the front edge of the second area b is located behind the front edges of the first area a and the third area c, and the rear edge of the V-shaped structure and the front edge of the first guide slope 10 together form an upwardly arched third ridge 13. The third ridge 13 is provided to quickly divert and guide the accumulated water to the first ridge 11 and the second ridge 12.

[0028] The side wall of the first area a that is connected to the second area b gradually tilts and extends into the second area b from the back to the front to form a fourth guide slope 40, and the front end of the fourth guide slope 40 is smoothly connected to the rear side wall of the V-shaped structure. The side wall of the third area c that is connected to the second area b gradually tilts and extends into the second area b from the back to the front to form a fifth guide slope 50, and the rear side wall of the V-shaped structure at the front end of the fifth guide slope 50 is smoothly connected. The above structure is conducive to improving the guide effect between the first area a, the second area b, and the third area c, and avoiding water accumulation between the three.

This structure is conducive to further improving the water guiding effect.

[0030] The lower surface of the protruding portion 100 forms a sixth flow guiding slope 60 which gradually slopes upward outward from the second convex ridge 12 near the rear edge. This structure is conducive to gathering the accumulated water at the rear edge of the door body to the second convex ridge 12.

[0031] The cleaning machine of this embodiment comprises a water tank 2 with an open top, and also comprises the above-mentioned door assembly, and a hinge 3 for rotatably connecting the door assembly to the open rear edge of the top of the water tank is provided at the rear edge of the door assembly.

[0032] The inner wall of the door of the present embodiment adopts a structure with a high front and a low back. When the door is closed, it is easy for water droplets on the lower surface of the door to slide down, avoiding water hanging on the lower surface of the door. When the door is open, due to the existence of the guide structure, its bottom area sinks into the cavity range of the cleaning machine, which is conducive to the water attached to the lower surface of the door to fall into the inner cavity of the cleaning machine, avoiding problems such as water accumulation in the hinge area of ​​the door, and is conducive to improving user experience. In addition, the first ridge 11 and the second ridge 12 are used to converge water flow, and the water flow is converged at the bottom of the linear ridge with a small contact area. Compared with a flat surface, it is more difficult for water droplets to adhere. Under the condition of hot air blowing, water droplets are easier to drip, so that the surface of the inner plate is thoroughly dried to achieve an ideal drying effect.
