Description

Technical Field

[0001] The utility model relates to a washing machine for washing tableware and / or fruits and vegetables. Background Art

[0002] At present, the upper spray arm water pipe of the dishwasher in the industry is generally installed on the bowl basket. After the bowl basket is placed in the washing chamber, the upper spray arm water pipe is then connected to the water supply pipe located on the side wall of the washing chamber, so as to transport washing water from bottom to top. Because the bowl basket may need to be adjusted in height during use, or the bowl basket needs to be removed from the tank body in order to facilitate the placement of tableware on the bowl basket, the upper spray arm water pipe and the water supply pipe need to be movably connected.

[0003] For example, in the Chinese utility model patent with patent number CN202320063878.4 (publication number CN219206811U), the connection structure between the water supply pipe and the spray arm and the cleaning machine using the connection structure are disclosed. In order to facilitate the alignment of the connection pipe with the water outlet and realize the rapid connection between the connection pipe and the lifting plate, a guide is provided on the lifting plate above and / or below the water outlet, and the guide is inclined from the direction of the pipe body toward the spray arm toward the direction away from the water outlet. The guide plays a guiding role, guiding the connection pipe toward the direction of the water outlet.

[0004] Currently, the guide piece for guiding the connecting pipe is basically arranged on the water supply pipe, and the form is relatively simple. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a novel cleaning machine which can align the water pipe with the water outlet in view of the current status of the prior art.

[0006] The utility model solves the above technical problems by adopting the following technical solution: a cleaning machine comprising

[0007] A box body having an inner cavity with an open top or side;

[0008] A shelf is movably disposed in the inner cavity;

[0009] a water supply pipe having a water outlet at the rear of the inner cavity;

[0010] The spray assembly comprises a water pipe for conveying water flow and a spray hole for spraying water in the water pipe, wherein the water pipe is installed on a shelf, the spray hole faces the shelf, the water pipe can be docked with a water outlet and fluidly connected, at which time the water pipe extends in a front-to-back direction, and the shelf is arranged horizontally; or the water pipe can be detached from the water outlet and fluidly disconnected;

[0011] It is characterized in that the box body is provided with a first guide member located at the front thereof, and the shelf is provided with a second guide member that can abut against the first guide member. When the first guide member and the second guide member abut against each other in the front-to-back direction, the water pipe moves backward toward the water outlet of the water supply pipe.

[0012] The shelf has multiple movable forms. Preferably, the cleaning machine also includes a connecting piece located in the inner cavity. The shelf can be rotated up and down to a horizontal state or a vertical state, and the shelf can move up and down when in the vertical state, so that the shelf can be in a first position state or a second position state. When the shelf is in the first position state, the shelf is horizontally arranged, and the water pipe is connected to the water outlet and fluid is connected. When the shelf is in the second position state, the shelf is vertically arranged, and the water pipe is detached from the water outlet and the fluid is disconnected. The shelf is located in the inner cavity in the above two positions, so there is no need to prepare space outside the box to place the shelf and the spray assembly.

[0013] The connecting member can have various structural forms, such as a rope, but this is not good for the positioning and guiding effect of the shelf during its movement. Therefore, the connecting member is in the shape of a rod with an axis extending in the horizontal direction. The shelf can rotate around the axis of the connecting member to a horizontal state or a vertical state, and the shelf can move up and down relative to the connecting member when in the vertical state, so that the shelf can be in a first position state or a second position state.

[0014] In order to guide the trajectory of the vertical movement of the shelf, a guide rail is provided on the shelf, and one end of the connecting member extends into the guide rail. When the shelf is in the first position, the guide rail extends in the front-to-back direction. When the shelf is in the vertical state, the guide rail extends vertically and slidably cooperates with the connecting member.

[0015] The guide rail can have a variety of structural forms, one of which is that the connecting member is located at the rear of the inner cavity, and when the shelf is in the second position, the shelf is arranged adjacent to the rear wall of the inner cavity, and the backward folding is more ergonomic. Of course, the connecting member can also be located at the front of the inner cavity, and when the shelf is in the second position, the shelf is arranged adjacent to the front wall of the inner cavity.

[0016] The guide rail can have a variety of structural forms, one of which is that the connecting member is at the same height as the water outlet, the guide rail includes a straight section and an inclined section, when the shelf is in the first position, the straight section extends in the front-to-back direction, the inclined section is connected to the rear end of the straight section, and the inclined section is inclined upward from front to back. In this form, when the shelf is turned over, the water pipe will not interfere with the water supply pipe.

[0017] The guide rail may have a variety of structural forms, and another structural form is that the connecting piece is located obliquely below the water outlet, and the guide rail extends straightly.

[0018] One of the matching modes of the first guide and the second guide is that when the guide rail is in a forward and backward extension state, the front end is the second guide, the first guide includes a guide portion and a placement portion located below the guide portion, the guide portion has an inclined surface tilted backward from top to bottom, the second guide can slide along the inclined surface, and the second guide can be placed on the bottom wall of the placement portion. In this way, when the shelf is turned over, the front end of the guide rail abuts against the inclined surface of the second guide, forcing the shelf to drive the water pipe to move backward.

[0019] Preferably, the second guide member is an arc segment that arches forward, and the side wall surface of the shelf portion facing the inner water pipe is an arc surface that matches a part of the arc segment, and the upper end of the arc surface is connected to the lower end of the inclined surface. In this way, the arc surface of the shelf portion can play a certain role in positioning the second guide member in the vertical direction, and at the same time will not affect the arc segment from escaping from the area formed by the arc surface.

[0020] Another structural form of the first guide and the second guide is: the first guide is an arc groove arranged on the front side wall of the box body, the arc groove is arched forward, and a roller that can be partially embedded in the arc groove is rotatably arranged on the shelf, and the rotation axis of the roller extends in the left and right direction, and the roller is the second guide. In the process of flipping and pressing the shelf, the roller rotates around the shelf. In this process, the roller enters the arc groove, pushes the shelf to flatten and move backward, so that the water outlet of the water pipe and the water supply pipe are connected, and the rolling friction of the roller makes the flipping process feel smoother.

[0021] Compared with the prior art, the utility model has the following advantages: the utility model sets a first guide member in the box body, and sets a second guide member on the shelf. When the water pipe moves with the shelf and docks with the water outlet, the first guide member and the second guide member will abut against each other in the front and rear directions, so that the shelf drives the water pipe to move backward, so that the water pipe docks with the water outlet and is fluidically connected. Compared with the existing method of setting a guide member on the water supply pipe, the structure is novel. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] Example 1

[0033] like Figures 1 to 4 As shown, the washing machine of this preferred embodiment is used for washing tableware and / or fruits and vegetables, and the tableware includes bowls, plates, pots and the like.

[0034] The cleaning machine comprises a housing 1 , a shelf 2 , a water supply pipe 3 , a spray assembly, a first guide member 4 and a second guide member 5 .

[0035] The box body 1 has an inner cavity 10 with an open top or side. In this embodiment, the inner cavity 10 is open at the top. The water supply pipe 3 is provided with a water outlet 31 located at the rear of the inner cavity 10. The water supply pipe 3 can be located in the inner cavity 10 as a whole or partially.

[0036] The spray assembly includes a water pipe 6 for conveying water flow and a spray hole for spraying water in the water pipe 6. The spray hole can be directly arranged on the water pipe 6, or the water pipe 6 can be connected to the spray part 61, and the spray hole is arranged on the spray part 61.

[0037] The water pipe 6 is installed on the shelf 2, and the two can adopt the existing snap connection form or other existing connection forms. The spray hole faces the shelf 2, and the shelf 2 can be movably arranged in the inner cavity 10. The water pipe 6 can be connected with the water outlet 31 and fluidly connected. At this time, the water pipe 6 extends in the front and rear direction, and the shelf 2 is horizontally arranged; or, the water pipe 6 can be detached from the water outlet 31 and the fluid is disconnected.

[0038] Specifically, a connecting piece 7 is provided in the inner cavity 10 , and the connecting piece 7 can be directly set on the side wall of the inner cavity 10 . In this embodiment, a bowl rack 8 is also provided in the inner cavity 10 , and the connecting piece 7 is fixedly set on the top of the bowl rack 8 .

[0039] The connecting member 7 is in the shape of a rod with an axis extending in the horizontal direction. The shelf 2 can rotate around the axis of the connecting member 7 to a horizontal state or a vertical state, and the shelf 2 can move up and down relative to the connecting member 7 when in the vertical state, so that the shelf 2 can be in a first position state or a second position state. When the shelf 2 is in the first position state, the shelf 2 is horizontally arranged and located above the bowl rack 8, and the water pipe 6 is connected to the water outlet 31 and fluidly connected. When the shelf 2 is in the second position state, the shelf 2 is vertically arranged and located beside the bowl rack 8, that is, the shelf 2 is located outside the accommodating space 80 of the bowl rack 8, the water pipe 6 is disengaged from the water outlet 31 and fluidly disconnected, and the shelf 2 is located in the inner cavity 10 in the above two positions, so there is no need to prepare space outside the box body 1 for placing the shelf 2 and the spray assembly.

[0040] A guide rail 21 is provided on the shelf 2, and one end of the connecting member 7 extends into the guide rail 21. When the shelf 2 is in the first position, the guide rail 21 extends in the front-to-back direction. When the shelf 2 is in the vertical state, the guide rail 21 extends vertically and slidably cooperates with the connecting member 7 to guide the vertical movement trajectory of the shelf 2.

[0041] In this embodiment, the connecting member 7 is located at the rear of the inner cavity 10. When the shelf 2 is in the second position, the shelf 2 is arranged adjacent to the rear wall of the inner cavity 10, and the backward folding is more in line with ergonomics. Of course, the connecting member 7 can also be located at the front of the inner cavity 10. When the shelf 2 is in the second position, the shelf 2 is arranged adjacent to the front wall of the inner cavity 10.

[0042] The height of the connecting member 7 is substantially the same as that of the water outlet 31. The guide rail 21 includes a straight section 211 and an inclined section 212. When the shelf 2 is in the first position, the straight section 211 extends in the front-to-back direction, and the inclined section 212 is connected to the rear end of the straight section 211. The inclined section 212 is inclined upward from front to back. In this form, when the shelf 2 is turned over, the water pipe 6 will not interfere with the water supply pipe 3.

[0043] A first guide member 4 is provided in the box body 1 at the front thereof, and a second guide member 5 which can abut against the first guide member 4 is provided on the shelf 2. When the first guide member 4 and the second guide member 5 abut against each other in the front-to-back direction, the water pipe 6 moves backward toward the water outlet 31 of the water supply pipe 3 so that the water pipe 6 and the water outlet 31 are docked and connected.

[0044] In this embodiment, when the guide rail 21 is in the forward and backward extension state, the front end is the second guide member 5, the first guide member 4 includes a guide portion 41 and a resting portion 42 located below the guide portion 41, the guide portion 41 has an inclined surface 411 tilted backward from top to bottom, the second guide member 5 can slide along the inclined surface 411, and the second guide member 5 can rest on the bottom wall of the resting portion 42. In this way, when the shelf 2 is turned over, the front end of the guide rail 21 abuts against the inclined surface 411 of the second guide member 5, forcing the shelf 2 to drive the water pipe 6 to move backward.

[0045] In addition, the second guide member 5 is an arc segment that arches forward, and the side wall surface of the shelf portion 42 facing the water supply pipe 3 is an arc surface 422 that matches the part of the arc segment, and the upper end of the arc surface 422 is connected to the lower end of the inclined surface 411. In this way, the arc surface 422 of the shelf portion 42 can play a certain positioning role in the vertical direction of the second guide member 5, and at the same time will not affect the arc segment 213 from escaping from the area formed by the arc surface 422.

[0049] 2. The first guide member 4 of this embodiment is an arc groove 11 arranged on the front side wall of the box body 1. The arc groove 11 is arched forward. A roller that can be partially embedded in the arc groove 11 is rotatably provided on the shelf 2. The rotation axis of the roller extends in the left-right direction. The roller is the second guide member 5. In the process of flipping and pressing the shelf 2, the roller rotates around the shelf 2. In this process, the roller enters the arc groove 11, pushing the shelf 2 to flatten and move backward, so that the water pipe 6 and the water outlet 31 of the water supply pipe 3 are connected. The rolling friction of the roller makes the flipping process feel smoother. In this embodiment, the shelf 2 is a hollow structure composed of multiple frame bars, and the roller is rotatably sleeved on one of the frame bars 20.
