Technical Field
[0001] The utility model relates to the technical field of dishwashers, in particular to a washing machine for tableware, fruits and vegetables. Background Art
[0002] Built-in dishwashers are common in kitchens. They are large in size and usually have a front-opening structure.
[0003] For example, the Chinese invention patent application with application publication number CN117838000A, "An automatic door lock device for a washing machine and a dishwasher" (application number: CN202410049895.1), discloses a front-opening dishwasher. The lower edge of the door of the dishwasher is rotatably connected to the lower edge of the front opening of the dishwasher body. When the door is closed, the top edge of the door is locked and connected to the dishwasher body through the door lock device.
[0004] At present, most front-loading dishwashers use the above-mentioned door locking structure. For dishwashers using this structure, the door body is relatively high, and the door body and the machine body are only locked at the top. If the water column hits the door body with great force during high-temperature washing, it may cause the seal between the door body and the machine body to be unstable, resulting in leakage of hot water and hot air, affecting normal use.
[0005] Therefore, for the current cleaning machine structure, further improvement needs to be made. Summary of the invention
[0006] The technical problem to be solved by the utility model is to provide a cleaning machine capable of improving the sealing reliability of the door body in view of the current status of the prior art.
[0007] The technical solution adopted by the utility model to solve the above technical problems is:
[0008] A cleaning machine comprises a machine body and a door assembly, wherein the machine body is provided with a front opening, and the lower edge of the door assembly is rotatably connected to the lower edge of the front opening of the machine body. The door assembly comprises a door frame, a door body and a limiting assembly, wherein the door body is arranged at the front side of the machine body around the edge of the front opening, the door body matches the inner opening of the door frame and the lower edge is rotatably connected to the lower edge of the inner opening of the door frame, and the limiting assembly comprises a first part arranged in the middle of the outer side wall of the door body and a second part arranged in the middle of the inner side wall of the door frame, wherein the first part cooperates with the second part to limit in a closed state, and the first part is relatively separated from the second part in an open state.
[0009] The utility model arranges the door body assembly as a door frame connected to the machine body and a door body which can be flipped and arranged in the door frame. The cooperation between the door body and the door frame is more compact. In the closed state, the top of the door body and the top of the door frame can still be locked by the door lock structure. At the same time, the middle of the door frame and the middle of the door body are limited, which is beneficial to improving the reliability of the door body sealing. The limiting structure does not affect the door opening action when opening the door, and is easy to use.
[0010] Preferably, the door frame is provided with a receiving groove extending backward from its front side wall, and a first limiting member that can move closer to or farther from the door body is provided in the receiving groove, and correspondingly, a second limiting member is provided on the outer side wall of the door body, and the first limiting member and the second limiting member are detachably matched to limit the position. The detachable matching structure of the first limiting member and the second limiting member is adopted to conveniently achieve the effect of limiting the door closing and automatically avoiding the door opening.
[0011] Preferably, the first limiting member is a limiting column that can reciprocate relative to the door body, and the limiting column always maintains a tendency to move toward the door body, and the middle part of the second limiting member is provided with a limiting groove that extends vertically and is for the limiting column to be clamped therein, and the front side wall and the rear side wall of the second limiting member are respectively smoothly transitioned to the limiting groove. More preferably, the limiting groove and the part that smoothly transitions thereto together form a structure with a 3-shaped cross section. The above structure can ensure reliable limiting in the closed door state, smooth and labor-saving door opening, and convenient operation.
[0012] Preferably, the top and bottom of the limit column are respectively provided with limit blocks, the door frame is provided with a slide groove extending along the moving direction of the limit column, the limit block is slidably constrained in the slide groove, and an elastic member for driving the limit block to move toward the door body is provided in the slide groove. The limit column, the limit block, and the elastic member together constitute the second part, and the second limit member constitutes the first part. The above structure is adopted to improve the reliability of the second part limiting the first part, and improve the stability of the second part state switching during the door opening and closing process.
[0013] Preferably, a guide column extending along the moving direction of the limit column is provided in the slide groove, the limit block is slidably connected to the guide column, and the elastic member is sleeved on the outer periphery of the guide column and elastically compressed in the slide groove outside the limit block. This structure is conducive to further improving the moving stability of the second part.
[0014] Preferably, the inner side of the door body is provided with a convex rib arranged near the edge, and a sealing ring is provided around the convex rib, and when the door is closed, the sealing ring is squeezed and sealed with the convex rib and the inner side wall of the door frame respectively.

When the door is closed, the rear surface of the rib, the rear surface of the sealing ring and the rear surface of the door frame are aligned, and the notch forms a buffer zone located outside the sealing ring. During the cleaning process, water hitting the inner side wall of the door body tends to accumulate at the edge when falling. With the above structure, the accumulated water can cross the sealing ring and flow down through the buffer zone, so as to prevent the accumulated water from accumulating too much at the sealing ring and causing leakage.
[0016] Preferably, the inner side wall of the door body located within the convex rib forms a guide surface that arches outward from the upper and lower edges to the middle. This structure can guide the water hitting the inner surface of the door body downward in time to avoid serious water hanging on the inner wall of the door body.
[0017] Further preferably, a door inner plate is embedded in the convex rib of the door body, and the guide surface is formed on the door inner plate. The door inner plate can be made of a material with good sound insulation and good hydrophobicity to further prevent water from hanging on the inner surface of the door body and reduce noise.
[0018] Compared with the prior art, the advantages of the present invention are: the present invention arranges the door body assembly as a door frame connected to the machine body and a door body which can be flipped in the door frame. The cooperation between the door body and the door frame is more compact. In the closed state, the top of the door body and the top of the door frame can still be locked by the door lock structure. At the same time, the middle of the door frame and the middle of the door body are limited, which is beneficial to improve the reliability of the door body sealing. The limiting structure does not affect the door opening action when opening the door, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0026] like Figure 1As shown in Figure 6, the cleaning machine of this embodiment includes a machine body 5 and a door assembly A. The machine body 5 is provided with a front opening 51, and the lower edge of the door assembly A is rotatably connected to the lower edge of the front opening 51 of the machine body 5.
[0027] In this embodiment, the door body assembly A includes a door frame 1, a door body 2 and a limiting assembly 3. The door body 2 is arranged on the front side of the body 5 around the edge of the front opening 51. The door body 2 matches the inner opening of the door frame 1 and the lower edge is rotatably connected to the lower edge of the inner opening of the door frame 1. The limiting assembly 3 includes a first part arranged in the middle of the outer wall of the door body 2 and a second part arranged in the middle of the inner wall of the door frame 1. In the closed state, the first part and the second part cooperate to limit, and in the open state, the first part and the second part are relatively separated.
[0028] Specifically, the door frame 1 is provided with a receiving groove 11 extending backward from its front side wall, and a first position-limiting member 31 which can be moved closer to or farther from the door body 2 is provided in the receiving groove 11. Correspondingly, a second position-limiting member 32 is provided on the outer side wall of the door body 2, and the first position-limiting member 31 and the second position-limiting member 32 are detachably matched for position limiting. The detachable matching structure of the first position-limiting member 31 and the second position-limiting member 32 is adopted to conveniently achieve the effect of position limiting when closing the door and automatically avoiding when opening the door.
[0029] The first limiting member 31 is a limiting column that can reciprocate relative to the door body 2, and the limiting column always maintains a tendency to move toward the door body 2. The middle part of the second limiting member 32 is provided with a limiting groove 321 extending vertically and for the limiting column to be clamped therein. The front side wall and the rear side wall of the second limiting member 32 are respectively smoothly transitioned and connected with the limiting groove. The limiting groove 321 and the part that smoothly transitions therewith form a structure with a 3-shaped cross section. The above structure can ensure reliable limiting in the closed door state, smooth and labor-saving door opening process, and convenient operation.
[0030] The top and bottom of the limiting column are respectively provided with limiting blocks 311, and a slide groove 12 extending along the moving direction of the limiting column is provided in the door frame 1. The limiting block 311 is slidably restrained in the slide groove 12, and an elastic member 332 is provided in the slide groove 12 for driving the limiting block 311 to move toward the door body 2. The limiting column, the limiting block 311, and the elastic member 332 together constitute the second part, and the second limiting member 32 constitutes the first part. The above structure is adopted to improve the reliability of the second part limiting the first part, and improve the stability of the second part state switching during the door opening and closing process.
[0031] A guide post 13 extending along the moving direction of the limit post is provided in the slide groove 12, the limit block 311 is slidably connected to the guide post 13, and the elastic member 332 is sleeved on the outer periphery of the guide post 13 and elastically compressed in the slide groove 12 outside the limit block 311. This structure is conducive to further improving the movement stability of the second part.
[0032] The inner side of the door body 2 is provided with a convex rib 21 arranged near the edge, and the outer periphery of the convex rib 21 is provided with a sealing ring 22. When the door is closed, the sealing ring 22 is squeezed and sealed with the convex rib 21 and the inner wall of the door frame 1. Such a structure is adopted to improve the sealing reliability between the door body and the door frame.
[0033] A notch 52 is provided on the front side wall of the machine body 5 near the sealing ring 22. When the door is closed, the rear surface of the rib 21 and the rear surface of the sealing ring 22 are aligned with the rear surface of the door frame 1, and the notch 52 forms a buffer zone outside the sealing ring 22. During the cleaning process, water hitting the inner side wall of the door body 2 tends to accumulate at the edge when falling. With the above structure, the accumulated water can cross the sealing ring 22 and flow down through the buffer zone, so as to prevent the accumulated water from accumulating too much at the sealing ring 22 and causing water leakage.
[0034] The inner wall of the door body 2 located inside the rib 21 forms a guide surface 231 that arches 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 to avoid serious water hanging on the inner wall of the door body. A door inner plate 23 is embedded in the rib 21 of the door body 2, and the 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 hydrophobicity to further avoid water hanging on the inner surface of the door body and reduce noise.
[0035] The front side wall of the door body 2 may be provided with a handle arranged near the top.
[0036] In this embodiment, the door body assembly A is configured as a door frame 1 connected to the machine body 5 and a door body 2 that can be flipped in the door frame 1. The door body 2 and the door frame 1 are more compactly matched. 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. At the same time, the middle of the door frame 1 and the middle of the door body 2 are limited, which is beneficial to improving the reliability of the door body sealing. The limiting structure does not affect the door opening action when opening the door, and is easy to use.
