Description

Technical Field

[0001] The invention relates to a kitchen appliance, in particular to a washing machine for washing dishes, vegetables or fruits. Background Art

[0002] As people's living standards continue to improve, dishwashers, as a kitchen appliance, are increasingly entering households. Dishwashers on the market are generally divided into three types: tabletop, cabinet, and tank. Among them, tabletop dishwashers are integrated independent structures and are generally placed on the table for use; cabinet dishwashers are also independent structures, but need to be embedded in kitchen cabinets for use; tank dishwashers are combined with sinks and are generally installed in kitchen cabinets for use.

[0003] At present, the structure of the relatively mature water tank type cleaning machine on the market is mainly as described in the Chinese patent "Water Tank Type Cleaning Machine" (application number: CN201310750968.1) with the authorization announcement number CN104224074B, that is, it includes a box body forming a washing space, the box body includes a water tank body and a cover plate rotatably connected to the water tank body, the bottom of the water tank body has a concave drain area at least in the central part, and the drain area is provided with a water pump that pumps the water in the drain area out to the washing space above the drain area, the drain area is covered with a drain plate with drain holes, and a rotating spray arm connected to the water pump fluid and having a water outlet hole is arranged above the drain plate. By setting a drain area covered with a drain plate and setting the water pump in the drain area, the water pump is isolated from the washing area, so that the water flowing back into the water pump is first filtered by the drain plate.

[0004] The sink body of the above-mentioned existing sink-type cleaning machine is made of stainless steel material, and the processing methods are mainly welding and drawing. Among them, for the welding process, due to the large welding deformation of stainless steel materials, it is difficult to control the dimensional accuracy of the sink, which limits the overall shape of the sink body, resulting in a single structure of the sink body, which in turn restricts the development of more functional structures of the sink-type cleaning machine. In addition, the welding process has extremely high requirements for the welding mold, low welding efficiency and high cost; for the drawing process, the deformation limit of the stainless steel material directly limits the drawing depth of the sink. The sink drawn by the drawing process generally has a depth less than the opening width of the sink. At present, it is difficult for the processes around the world to achieve a drawing depth greater than the opening width of the sink body, which causes the sink to occupy a larger installation space in the kitchen during installation and greatly limits the washing space of the sink.

[0005] The plastic sink body is highly plastic, and the depth of the sink body can be increased as needed, so that the kitchen space can be effectively utilized. However, since the water pump of the cleaning machine is located at the bottom of the sink body, the spray arm at the bottom of the sink body needs to be installed and used in conjunction with the water pump, resulting in that although the depth of the sink body is increased, the space in the top area of ​​the sink body cannot be effectively utilized. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a cleaning machine which can make the upper space of the water tank body be used independently and improve the space utilization rate of the water tank body in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a cleaning machine, comprising a sink body with a washing chamber, characterized in that: a drain plate is detachably arranged in the sink body so that the upper space and the lower space of the washing chamber can be arranged relatively independently, and a first drain port for draining water in the upper space is opened on the side wall of the sink body, and a return water structure is provided at the first drain port, which can prevent water from splashing out of the first drain port when the drain plate is removed from the sink body and the cleaning machine is in the cleaning state.

[0008] Preferably, the first drain port is covered with a baffle plate, a second drain port is formed on the baffle plate, and the water return structure is arranged in the second drain port. The structural component is easy to produce and assemble, and the length of the water return structure can be extended as needed, thereby improving the water return effect without affecting the drainage effect.

[0009] Preferably, at least a portion of the inner side wall of the upper portion of the water tank body is formed as a first inclined surface that gradually slopes outward from bottom to top, and the inner wall surface of the baffle is formed as a second inclined surface that matches the first inclined surface. With such a structure, it is convenient to drain the water in the upper space and avoid splashing of water sprayed upward by the spray arm of the cleaning machine in the cleaning state.

[0010] Preferably, the second drain port is opened on the second inclined surface and the inner bottom wall gradually slopes upward from the inside to the outside, which is conducive to further strengthening the above-mentioned drainage and water return functions.

[0011] In each of the above schemes, the water return structure includes a first baffle and a second baffle spaced apart from each other, the two ends of the first baffle and the two ends of the second baffle are respectively connected to the inner side walls of the second drain port arranged opposite to each other, the outer edge of the first baffle is bent upward and connected to the inner top wall of the second drain port to enclose a water return cavity, and the outer edge of the second baffle is bent upward to form a water return groove. A first gap for water discharge is formed between the second baffle and the inner bottom wall of the second drain port, and a second gap for water discharge is formed between the upper edge of the water return groove and the lower wall of the first baffle. When the drain plate is placed in the cleaning machine, the lower space and the upper space of the sink body are relatively sealed. The lower space can be used for normal washing of dishes, fruits and vegetables, and the upper space is used as a sink. The accumulated water on the drain plate can be discharged through the first gap on the second drain outlet. When a lot of water accumulates on the drain plate, the accumulated water can also be discharged through the second gap. The drain plate is taken out from the sink body. When the cleaning machine is in the cleaning state, the water sprayed upward by the spray arm splashes onto the inner wall of the sink body and is blocked back at the return water chamber and the return water groove, thereby avoiding water discharge and affecting the water volume in the cleaning state.

[0012] Preferably, the vertical width of the first gap gradually increases from the inside to the outside. The first baffle and the second baffle are gradually inclined upward from the inside to the outside along the water flow direction. This structure is conducive to preventing the water sprayed upward by the spray arm from being discharged through the first gap.

[0013] Preferably, the inner edge of the first baffle has a downwardly bent baffle, and the lower edge of the baffle is aligned with the upper edge of the return groove or arranged lower than the upper edge of the return groove. The inner wall surface of the baffle is flush with the inner wall surface of the baffle. This structure is conducive to preventing the water sprayed upward by the spray arm from being discharged through the second gap.

[0014] Preferably, a drain pipe capable of outputting the discharged water is connected to the outer side of the second drain port of the baffle.

[0015] To facilitate assembly, the main part of the baffle is arranged on the outside of the sink body and the inner side of the baffle has a plug-in portion that can be inserted into the first drain outlet, the second drain outlet is opened on the plug-in portion, and the outer edge of the plug-in portion is provided with a slot arranged around the plug-in portion, and a sealing ring is embedded in the slot to abut against the outer wall of the sink body.

[0016] Preferably, the edge of the drain plate has a vertically arranged perimeter, on which a plurality of water outlets are arranged at intervals and corresponding to the first drain outlet and the second drain outlet. In addition to the drainage function, the water outlets can also play a filtering role to prevent debris from clogging the second drain outlet.

[0017] As an improvement, the outer wall of the drain plate is provided with a guide groove that can prevent water in the upper space from falling into the lower space, and the guide groove is respectively connected to the water outlet and the second drain port. The outer periphery of the surrounding edge is provided with a seal that can match and abut against the inner wall of the water tank body, and the guide groove is formed on the outer wall of the seal. With such a structure, when the drain plate is placed in the water tank body, the upper space and the lower space can be sealed and separated, so that the accumulated water in the upper space can be directly discharged without entering the lower space to affect cleaning.

[0018] Compared with the prior art, the advantages of the present invention are: a drain plate is arranged in the sink body, which divides the washing chamber into relatively independent upper and lower spaces. When the drain plate is placed in the sink body, the lower space can be used as a washing machine for washing dishes, fruits and vegetables, etc., while the upper space can be used as a separate sink, or for placing washed dishes, fruits and vegetables, and the accumulated water can be discharged from the first drain port; when the drain plate is taken out from the sink body, the water sprayed upward by the spray arm of the washing machine splashes on the inner wall of the sink body and can be blocked by the water return structure, thereby avoiding water loss in the sink. The structure of the present invention improves the utilization rate of the space inside the sink body, and brings great convenience to the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 6As shown, the cleaning machine of this embodiment is a water tank type cleaning machine, which is installed on a cabinet countertop for use. The cleaning machine of this embodiment includes a water tank body 1 having a washing cavity 10, and the water tank body 1 has a spray arm rotatably arranged at the bottom of the water tank body 1. The water tank body 1 is detachably provided with a drain plate 2 that enables the upper space 101 and the lower space 102 of the washing cavity 10 to be relatively independently arranged.

[0027] In the present embodiment, a first drain port 11 is provided on the side wall of the sink body 1 for draining water in the upper space 101. The first drain port 11 is covered with a baffle plate 3, and a second drain port 31 is provided on the baffle plate 3. The baffle plate 3 is also provided with a return water structure 32 that can prevent water from splashing out of the second drain port 31 when the drain plate 2 is removed from the sink body 1 and the cleaning machine is in the cleaning state.

[0028] Specifically, the inner side wall portion of the upper part of the water tank body 1 is formed as a first inclined surface 12 that gradually tilts outward from bottom to top, and the inner wall surface of the baffle 3 is formed as a second inclined surface 33 that matches the first inclined surface 12. With such a structure, it is convenient to drain the water in the upper space 101, and avoid splashing of the water sprayed upward by the spray arm in the cleaning state of the cleaning machine. The second drain port 31 is opened on the second inclined surface 33 and the inner bottom wall gradually tilts upward from the inside to the outside. The water return structure 32 is arranged in the second drain port 31, which is conducive to further strengthening the above-mentioned drainage and water return functions. The return water structure 32 of this embodiment includes a first baffle 321 and a second baffle 322 which are arranged parallel to each other and spaced apart from each other. The two ends of the first baffle 321 and the two ends of the second baffle 322 are respectively connected to the inner side walls of the second drain outlet 31 which are arranged opposite to each other. The outer edge of the first baffle 321 is bent upward and connected to the inner top wall of the second drain outlet 31 to enclose a return water cavity 323. The outer edge of the second baffle 322 is bent upward to form a return water groove 324. The bends on the first baffle 321 and the second baffle 322 are both formed into an arc-shaped structure 300 that arches outward to enhance the return water performance and prevent dirt accumulation. A first gap 325 for water discharge is formed between the second baffle 322 and the inner bottom wall of the second drain outlet 31, and a second gap 326 for water discharge is formed between the upper edge of the return water groove 324 and the lower wall of the first baffle 321. When the drain plate 2 is placed in the cleaning machine, the lower space 102 and the upper space 101 of the sink body 1 are relatively sealed. The lower space 102 can be used for normal washing of dishes, fruits and vegetables, and the upper space 101 is used as a sink. The accumulated water on the drain plate 2 can be discharged through the first gap 325 on the second drain port 31. When a lot of water accumulates on the drain plate 2, the accumulated water can also be discharged through the second gap 326. The drain plate 2 is taken out of the sink body 1. In the cleaning state of the cleaning machine, the water sprayed upward by the spray arm splashes onto the inner wall of the sink body 1 and is blocked back at the return water chamber 323 and the return water groove 324, thereby avoiding the discharge of water and affecting the water volume in the cleaning state.

[0029] The vertical width of the first gap 325 gradually expands from the inside to the outside. The first baffle 321 and the second baffle 322 are gradually inclined upward from the inside to the outside along the water flow direction. This structure is conducive to preventing the water sprayed upward by the spray arm from being discharged through the first gap 325. The inner edge of the first baffle 321 is provided with a downwardly bent rib 3211, and the lower edge of the rib 3211 is aligned with the upper edge of the return groove 324 or arranged lower than the upper edge of the return groove 324. The inner wall surface of the rib 3211 is flush with the inner wall surface of the baffle 3. This structure is conducive to preventing the water sprayed upward by the spray arm from being discharged through the second gap 326. The outer side of the second drain port 31 of the baffle 3 is connected to a drain pipe 35 that can output the discharged water. To facilitate assembly, the main part of the baffle 3 is arranged on the outside of the sink body 1 and the inner side of the baffle 3 has a plug-in portion 34 that can be inserted into the first drain port 11. The second drain port 31 is opened on the plug-in portion 34. The outer edge of the plug-in portion 34 is provided with a slot 341 arranged around the plug-in portion 34. A sealing ring 342 that abuts against the outer wall of the sink body 1 is embedded in the slot 341.

[0030] In this embodiment, the edge of the drain plate 2 has a vertically arranged perimeter 21, and a plurality of water outlets 22 are arranged at intervals and corresponding to the first drain port 11 and the second drain port 31. In addition to the drainage function, the water outlet 22 can also play a filtering role to prevent debris from blocking the second drain port 31. The outer wall of the drain plate 2 is provided with a guide groove 23 that can prevent the water in the upper space 101 from falling into the lower space 102. The guide groove 23 is formed by the outer peripheral wall of the drain plate 2 extending outward along the periphery of the water outlet 22, and the guide groove 23 is connected to the water outlet 22 and the second drain port 31 respectively. The outer perimeter of the perimeter 21 is provided with a seal 211 that can match and abut against the inner wall of the water tank body 1, and the seal 211 is sleeved at the upper edge of the drain plate 2. With such a structure, when the drain plate 2 is placed in the sink body 1, the upper space 101 and the lower space 102 can be sealed and separated, so that the accumulated water in the upper space 101 can be directly discharged without entering the lower space 102 to affect cleaning.

[0031] In this embodiment, a drain plate 2 is set in the sink body 1, and the drain plate 2 divides the washing chamber 10 into relatively independent upper space 101 and lower space 102. When the drain plate 2 is placed in the sink body 1, the lower space 102 can be used as a washing machine for washing dishes, fruits and vegetables, etc., and the upper space 101 can be used as a separate sink, or for placing washed dishes, fruits and vegetables, and the accumulated water can be discharged from the second drain port 31; when the drain plate 2 is taken out from the sink body 1, the water sprayed upward by the spray arm of the washing machine splashes on the inner wall of the sink body 1 and can be blocked by the water return structure 32, avoiding water loss in the sink. The structure of this embodiment improves the utilization rate of the space in the sink body 1, which brings great convenience to the user.
