Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a cleaning machine for cleaning tableware, fruits and vegetables. Background Technology

[0002] Front-loading dishwashers are common in home kitchens. These dishwashers are usually built-in and installed in cabinets, blending seamlessly with the cabinets after installation, which is quite aesthetically pleasing.

[0003] The applicant's earlier application CN202410864177.X, "An Installation Method for a Cleaning Machine," discloses a highly extendable cleaning machine structure, which includes an upper housing and a lower housing. The upper housing and the lower housing are connected by a telescopic structure that can extend and retract vertically. The upper housing and the lower housing are also provided with a drive mechanism that can drive the upper housing to move vertically relative to the lower housing through the telescopic structure. The top of the housing is provided with a detection structure that can cooperate with the inner top wall of the cabinet installation cavity to determine whether the installation is in place.

[0004] Using the above solution, when installing the cleaning machine, it can first be adjusted to a low height and placed in the cabinet mounting cavity. The upper cabinet then moves upwards relative to the lower cabinet via the drive mechanism and telescopic structure. This structure meets the installation requirements of cabinets of different heights, providing greater convenience. However, for cabinets with telescopic structures, the upward splashing water column often carries food residue, causing it to stick to the walls of the telescopic structure and affecting the cleaning effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cleaning machine that can prevent wall snagging at the telescopic structure and improve space utilization, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A washing machine includes a housing with a telescopic structure in the middle that allows it to extend and retract vertically to adjust the height of the housing. The housing has an upper bowl basket and a lower bowl basket arranged at intervals. It also includes a bracket covering the top opening of the lower bowl basket. The bracket is located below the telescopic structure and has a limiting rib on its upper surface for placing large tableware. The lower surface of the bracket forms a flow-limiting structure that can block upward splashing water jets.

[0008] With the above structure, the covered lower dish rack is mainly used to place shorter tableware, while the bracket is located below the telescopic structure and has a large gap between it and the upper dish rack above it, which can be used to place larger tableware, making full use of the space in the washing chamber and improving space utilization. The lower surface of the bracket forms a flow-limiting structure that can block the upward splashing water column. This structure can prevent the main spray water column at the bottom of the washing machine from splashing upward and towards the telescopic structure on the side wall after passing through the lower dish rack, thereby avoiding the problem of wall hanging at the telescopic structure.

[0009] Preferably, the two side edges of the bracket are detachably connected to the top side edge of the lower dish rack. Detachably mounting the bracket on top of the lower dish rack facilitates the placement of tableware; after the tableware is placed, the combined unit can be pushed into the washing chamber for convenient use.

[0010] To facilitate the detachable connection of the side panels, the top side edge of the lower basket is provided with a slot extending forward and backward, and correspondingly, the side edge of the bracket is provided with a plug arm that can be inserted into the slot.

[0011] Preferably, the side edge of the top of the lower basket is provided with a vertically arranged assembly plate. The inner side wall of the assembly plate is provided with a first limiting piece and a second limiting piece that extend forward and backward and are arranged vertically at intervals. The outer edge of the first limiting piece is bent downward to form a first retaining edge, and the outer edge of the second limiting piece is bent upward to form a second retaining edge. The slot is formed between the first limiting piece and the second limiting piece, and an opening is formed between the first retaining edge and the second retaining edge for the connecting structure of the bracket to pass through. This structure facilitates the sliding connection of the plug-in arm in the forward and backward direction, making operation convenient.

[0012] Preferably, the upper surface of the first limiting piece forms a guide slope that gradually slopes downwards from the outside to the inside of the basket. The second limiting piece has a drain outlet that runs vertically through it for draining water. In this invention, the bracket blocks water splashing upwards and to the side walls, while allowing water at the edges to drain away promptly through the guide slope and drain outlet, eliminating residual water and preventing bacterial growth.

[0013] To facilitate installation and assembly, an L-shaped connecting piece is formed on the lower edge of the bracket. The vertical part of the L-shaped connecting piece is connected to the bottom edge of the bracket, and the end of the horizontal part of the L-shaped connecting piece is connected to the plug-in arm. In the assembled state, the horizontal part of the L-shaped connecting piece is arranged through the opening.

[0014] Preferably, the upper and lower surfaces of the front end of the connector arm are respectively provided with a first flexible limiting part that gradually curves upward from front to back, and the upper and lower surfaces of the rear end of the connector arm are respectively provided with a second flexible limiting part that gradually curves upward from back to front. This flexible part can be a silicone sheet injection-molded onto the connector arm, which does not affect assembly or disassembly, and can provide good limiting effect after assembly, preventing the connector arm from disengaging from the slot.

[0015] In this invention, the housing is equipped with a bottom spray arm and a top spray arm. The bottom spray arm is located below the lower dish rack, and its top wall has a first spray hole that sprays water onto the lower dish rack above it. The top spray arm is located at the bottom of the upper dish rack, and its top and bottom walls have second spray holes that spray water onto the upper dish rack above it and the bracket below it, respectively. This structure avoids snagging on the walls of the telescopic structure while rationally distributing the water jets to achieve thorough cleaning of the tableware in the upper dish rack, bracket, and lower dish rack, thereby improving the cleaning effect.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets up a bracket covering the top opening of the lower dish rack in the cabinet. The covered lower dish rack is mainly used to place tableware with a small height, while the bracket is located below the telescopic structure and has a large gap between it and the upper dish rack above it, which can be used to place tableware with a larger volume, making full use of the space of the washing chamber and improving the space utilization rate; the lower surface of the bracket forms a flow-limiting structure that can block the upward splashing water column. This structure can prevent the main spray water column at the bottom of the washing machine from splashing upward and towards the telescopic structure on the side wall after passing through the lower dish rack, thereby avoiding the problem of wall hanging at the telescopic structure.

[0023] like Figures 1-5As shown, the cleaning machine in this embodiment includes a housing 1. A telescopic structure 2 is provided in the middle of the housing 1, which can extend and retract vertically to adjust the height of the housing 1. The telescopic structure 2 in this embodiment is consistent with the prior application CN202410864177.X, which is a corrugated sheet with upper and lower layers, and will not be described in detail here.

[0024] In this embodiment, the box 1 is provided with an upper bowl basket 4 and a lower bowl basket 5 arranged at intervals, and also includes a bracket 3 covering the top opening of the lower bowl basket 5. The bracket 3 is located below the telescopic structure and its upper surface is provided with a limiting rib 31 for placing large-volume tableware. The lower surface of the bracket 3 forms a flow-limiting structure that can block the upward splashing water column.

[0025] With the above structure, the covered lower dish rack 5 is mainly used to place tableware with smaller height, while the bracket 3 is located below the telescopic structure and has a large gap between it and the upper dish rack 4 above it, which can be used to place tableware with larger volume, making full use of the space of the washing chamber and improving space utilization. The lower surface of the bracket 3 forms a flow-limiting structure that can block the upward splashing water column. This structure can prevent the main spray water column at the bottom of the washing machine from splashing upward and towards the telescopic structure on the side wall after passing through the lower dish rack, thereby avoiding the problem of wall hanging at the telescopic structure.

[0026] The two sides of the bracket 3 are detachably connected to the top side edge of the lower dish rack 5. The bracket 3 is detachably set on the top of the lower dish rack 5, which makes it easy to place the tableware; after the tableware is placed, the two can be pushed into the washing chamber for convenient use.

[0028] A vertically arranged mounting plate 50 is provided on the side edge of the top of the lower bowl basket 5. The inner wall of the mounting plate 50 is provided with a first limiting piece 51 and a second limiting piece 52 that extend forward and backward and are spaced apart vertically. The outer edge of the first limiting piece 51 is bent downward to form a first retaining edge 511, and the outer edge of the second limiting piece 52 is bent upward to form a second retaining edge 521. A slot 53 is formed between the first limiting piece 51 and the second limiting piece 52. An opening 500 is formed between the first retaining edge 511 and the second retaining edge 521 for the connecting structure of the bracket 3 to pass through. This structure facilitates the sliding connection of the plug-in arm 32 in the forward and backward direction, making operation convenient.

[0029] The upper surface of the first limiting piece 51 forms a guide slope 512 that gradually slopes downwards from the outside to the inside of the basket 5. The second limiting piece 52 has a drain outlet 522 that runs vertically through it for draining water. In this embodiment, after the bracket 3 blocks the upward and side wall splashing water, the water at the edge can be drained away in time through the aforementioned guide slope and drain outlet, achieving no residual water and avoiding bacterial growth.

[0030] To facilitate installation and assembly, an L-shaped connecting piece 33 is formed on the lower edge of the bracket 3. The vertical part of the L-shaped connecting piece 33 is connected to the bottom edge of the bracket 3, and the end of the horizontal part of the L-shaped connecting piece 33 is connected to the plug arm 32. In the assembled state, the horizontal part of the L-shaped connecting piece is arranged through the opening 500.

[0031] The upper and lower surfaces of the front end of the connector arm 32 are respectively provided with a first flexible limiting part 321 that gradually curves upward from front to back, and the upper and lower surfaces of the rear end of the connector arm 32 are respectively provided with a second flexible limiting part that gradually curves upward from back to front. The flexible part can be a silicone sheet injection molded on the connector arm 32, which does not affect disassembly and assembly, and can play a good limiting role after assembly to prevent the connector arm 32 from disengaging from the slot 53.

The bottom spray arm is located below the lower bowl basket 5, and its top wall has a first spray hole that sprays water onto the lower bowl basket 5 above it. The top spray arm 6 is located at the bottom of the upper bowl basket 4, and its top and bottom walls have second spray holes that spray water onto the upper bowl basket 4 above it and the bracket 3 below it, respectively. By adopting the above structure, while avoiding the wall snagging of the telescopic structure, the sprayed water jets are reasonably distributed to achieve thorough cleaning of the tableware on the upper bowl basket 4, the bracket 3, and the lower bowl basket 5, thereby improving the cleaning effect.

[0033] In this embodiment, a bracket 3 is provided in the housing 1 to cover the top opening of the lower dish rack 5. The covered lower dish rack 5 is mainly used to place tableware with a small height, while the bracket 3 is located below the telescopic structure and has a large gap between it and the upper dish rack 4 above it, which can be used to place tableware with a larger volume, making full use of the space of the washing chamber and improving the space utilization rate. The lower surface of the bracket 3 forms a flow-limiting structure that can block the upward splashing water column. This structure can prevent the main spray water column at the bottom of the washing machine from splashing upward and towards the telescopic structure on the side wall after passing through the lower dish rack, thereby avoiding the problem of wall hanging at the telescopic structure.
