Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and particularly relates to a shelf structure for household appliances and a household appliance. Background Art

[0002] Household appliances such as dishwashers, as devices for automatically cleaning tableware such as bowls, chopsticks, plates, dishes, knives, forks, fruits, and vegetables, greatly facilitate people's lives. In the prior art, a washing cavity is provided inside the dishwasher, and a bowl rack assembly for placing tableware is provided in the washing cavity. In order to increase the number of items to be washed that can be placed, at least one bowl rack is usually provided, and it is preferably possible to make at least one of the bowl racks be in a use state or a storage state according to the number of items to be washed.

[0003] If the bowl rack is stored outside the dishwasher when not in use, it is still necessary to specifically set aside space to place the bowl rack, which is rather inconvenient. To address this problem, for example, the Chinese utility model patent with the patent number CN202221059984.7 (publication number CN217429968U) discloses "A Double-Layer Bowl Rack". In this double-layer bowl rack, a hollow cavity for holding tableware and open at the top is formed inside the fixed rack. Among the four side edges of the circumference of the fixed rack, any two opposite side edges are respectively provided with support structures on the inner side adjacent to the cavity. By folding or unfolding the first rack body and the second rack body of the shelf itself, after being assembled with the support structure of the fixed rack, it can be adjusted to different use states as needed. When the first rack body and the second rack body are arranged side by side to expand the entire shelf, the shelf has a sufficient support area, and after being assembled with the fixed rack, the hierarchical storage of the double-layer bowl rack can be realized. And when it is necessary to pick up and place the tableware on the lower layer, only need to stack the first rack body and the second rack body and turn the shelf to the side of the fixed rack, the operation is simple and the use is convenient.

[0004] When the shelf of this patent is in the folded state, it is located inside the fixed rack, so there is no need to prepare space outside the dishwasher to place the shelf. However, when the shelf is stored inside the fixed rack, it will interfere with the placement of tableware inside the fixed rack.

[0005] To address the above problems, the Chinese utility model patent with the patent number CN202321570947.7 (publication number CN219982822U) discloses "A Shelf Assembly and a Dishwasher Having the Same". The shelf assembly includes: a main shelf; a slide rail, the slide rail includes a connected horizontal rail section and a side rail section, the horizontal rail section is horizontally placed above or below the main shelf, and the side rail section is detachably connected to the main shelf; a sliding bracket, the sliding bracket is slidably arranged on the slide rail between an unfolded position and a storage position, and the sliding bracket is located on the horizontal rail section at the unfolded position to be suitable for horizontally placing objects.

[0006] Although this patent can make the sliding bracket located outside the main shelf when in the retracted position, without occupying the space inside the main shelf. However, such a shelf assembly has the following defects:

[0007] First, since the slide rail consists of a horizontal rail section and a side rail section, the sliding bracket is prone to jamming when passing through the connection between the horizontal rail section and the side rail section. Therefore, it is mentioned in paragraph

[0123] of this patent that in order to better place tableware, the sliding bracket is generally made of a hard material, and in order to facilitate the smooth commutation of the sliding bracket, the width of the sliding bracket should not be too large. Therefore, the width of a single sliding bracket can be set narrow, and the placement area can be increased by increasing the number of sliding brackets. In this way, when switching the state of the sliding bracket, it is necessary to move the sliding brackets one by one, which is rather cumbersome.

[0008] Second, the area of the sliding bracket in this patent is small and cannot hold many tableware items, and the sliding bracket cannot be made too large, otherwise the height of the side rail section needs to be relatively high, then the horizontal rail section will be at a relatively far distance from the main shelf, resulting in the sliding bracket being at a relatively high position, and the tableware on the sliding bracket is extremely likely to interfere with the top wall of the dishwasher, and it will also cause waste of the vertical space between the main shelf and the horizontal rail section.

[0009] Third, the sliding bracket in this patent is mounted between two slide rails. Since one end of the horizontal rail section is in a free state, the slide rail is prone to shaking during the sliding process of the sliding bracket, which will affect the sliding stability of the sliding bracket.

[0010] Fourth, regardless of the state of the sliding bracket, the horizontal rail section is always located above the lower bowl basket, which will affect the taking and placing of tableware in the lower bowl basket.

[0011] Fifth, the periphery of the main shelf in this patent is in an enclosed state, that is, the area of the accommodating space of the main shelf in the horizontal direction is fixed. Then, when placing some items such as pots and pans, it may not be possible to fit them; and because the side rail section of the slide rail needs to be provided beside the main shelf, the sliding bracket will also move to the side of the main shelf, which will result in a relatively large occupied space of the shelf assembly in the horizontal direction.

[0012] Not only will a bowl rack assembly be provided in a dishwasher, but also a bowl rack assembly will be provided in household appliances such as a disinfection cabinet, and the above-mentioned defects also exist. Utility Model Content

[0013] The first technical problem to be solved by the present utility model is to provide a shelf assembly for household appliances with a variable area of the accommodating space of the main body in view of the current situation of the prior art.

[0014] The second technical problem to be solved by the present utility model is to provide a household appliance applying the above-mentioned shelf assembly in view of the current situation of the prior art.

[0015] The technical solution adopted by the present utility model to solve the above first technical problem is as follows: A bowl rack structure for household appliances, including a bowl rack, the top of the bowl rack is open to form a first opening, and it is characterized in that the side of the bowl rack is open to form a second opening. The bowl rack structure further includes a shelf movably connected to the bowl rack. When the shelf is in the first position, the shelf extends horizontally and covers the first opening. When the shelf is in the second position, the shelf extends vertically and covers the second opening.

[0016] In order to enable the shelf to cover the first opening or the second opening, the bowl rack and the shelf are rotatably connected through a connecting member. The shelf can be rotated to a horizontal state or a vertical state, and when the shelf is in the vertical state, it can move up and down to the second opening of the bowl rack or above the bowl rack. When the shelf is switched from the first position to the second position, first rotate the shelf upward to the vertical state, and then move the shelf downward until the shelf is located at the second opening. When the shelf is switched from the second position to the first position, first move the shelf upward to the top of the bowl rack, and then rotate the shelf downward to the horizontal state. From the movement process of the shelf, it can be seen that there will be no problem of component interference and jamming when the shelf of the present utility model is switched between horizontal and vertical states, and the movement process of the shelf can proceed smoothly. Moreover, the form of the shelf flipping can make the size of the shelf larger, and even can cover the entire top opening of the bowl rack, enabling a larger number of tableware to be placed. And when the shelf is in the first position, it can be close to the bowl rack, being structurally compact in the vertical direction and not causing waste of vertical space.

[0017] The connecting member can be a rope, which binds the shelf and the bowl rack locally together without affecting the movement of the shelf. However, the constraint on the movement trajectory of the shelf during movement is relatively small. Therefore, preferably, the connecting member is in the shape of a rod with its axis extending horizontally, and the shelf can be rotated around the axis of the connecting member to a horizontal state or a vertical state, and when the shelf is in the vertical state, it can move up and down relative to the connecting member to the second opening of the bowl rack or above the bowl rack.

[0018] In the above solution, the axis of the connecting member extends in the left - right direction, and at this time the shelf flips back and forth; or, the axis of the connecting member extends in the front - back direction, and at this time the shelf flips left and right.

[0019] In order to guide the vertical movement trajectory of the shelf, the bowl rack structure further includes a guide rail. One end of the connecting member extends into the guide rail. When the shelf is in the vertical state, the guide rail extends vertically and is in sliding fit with the connecting member.

[0020] Preferably, the guide rail is provided on the shelf, and the connecting member is relatively fixedly installed on the bowl rack. When the shelf is in the first position, the guide rail extends horizontally to play a guiding role.

[0021] Preferably, the axis of the connecting member extends in the left - right direction. When the shelf is in the first position, the guide rail extends in the front - back direction. In this way, when the shelf is flipped, it flips back and forth, which is more convenient for the user to operate compared to flipping left and right.

[0022] When the shelf is in the second position, one form is that the shelf flips to the rear side of the bowl rack: when the shelf is in the first position, the connecting member is adjacent to the rear end of the guide rail. When the shelf is in the second position, the shelf is located at the rear side of the bowl rack. Flipping backward is more in line with ergonomics and is more convenient to operate.

[0023] In the scheme of the shelf flipping backward, the structure of the guide rail is as follows: the height where the connecting member is located is the same as the height of the water outlet. The guide rail includes a straight section that extends straight and an inclined section that extends obliquely. When the shelf is in the first position, the front end of the inclined section is connected to the rear end of the straight section. The straight section extends in the front - back direction, and the inclined section slopes upward from front to back. The connecting member extends into the inclined section; or, the guide rail extends straight.

[0024] Preferably, the connecting member is located at the top of the bowl rack. When the shelf is in the second position, the connecting member is lower than the highest point of the shelf. In this way, when the shelf is in the first position, there is enough space above it to place items.

[0025] Preferably, the cross - section of the bowl rack is square, and the connecting member is arranged adjacent to the corner of the bowl rack, so as to facilitate the shelf to flip to the side of the bowl rack. Preferably, when the shelf is in the first position, the shelf is supported on the bowl rack, and the stability of the shelf is good.

[0026] Preferably, a first limiting portion is provided on the shelf, and a second limiting portion is provided on the bowl rack. When the shelf is in the second position, the first limiting portion presses against the second limiting portion to position the shelf.

[0027] Preferably, when the shelf is in the first position, the vertical projection of the shelf falls within the vertical projection of the bowl rack, and the area of the vertical projection of the shelf accounts for 90% - 98% of the area of the vertical projection of the bowl rack. The area of the shelf is relatively large, and it can place a relatively large number of tableware.

[0028] Preferably, the shelf and the guide rail together form a U - shaped structure, and the ratio of the length l to the height h of the U - shaped structure is between 0.13 and 0.16. The thickness of the shelf is relatively thin, and it occupies little space in the thickness direction.

[0029] The technical solution adopted by the present utility model to solve the above - mentioned second technical problem is: a household appliance, characterized in that: it includes a box body and the above - mentioned bowl rack structure, the box body has an inner cavity with an open top or side, and the bowl rack structure is arranged in the inner cavity of the box body.

[0030] The household appliance can be a disinfection cabinet, or it can be a cleaning machine for cleaning tableware and / or fruits and vegetables.

[0031] To spray the items on the shelf, a spray assembly for spraying water onto the bowl rack structure is installed on the shelf. When the shelf is in the second position, the spray assembly extends vertically and is also located at the second opening.

[0032] Compared with the prior art, the advantages of the present utility model are as follows: The bowl rack of the present utility model not only has a first opening at the top, but also has a second opening at the side. When the shelf is in the first position, the first opening is shielded and the second opening is opened. This is equivalent to an expansion of the horizontal dimension of the accommodating space of the bowl rack, which is more suitable for the placement scenario of items with relatively large horizontal dimensions. For example, the handle of a pot is located outside the second opening, while the body of the pot is still located in the bowl rack, so that the pot will not fall out of the bowl rack. At the same time, in this state, tableware can also be placed on the shelf, increasing the number of tableware that the bowl rack structure can hold in total. When the shelf is in the second position, the first opening is opened and the second opening is shielded, which is equivalent to an expansion of the vertical dimension of the accommodating space of the bowl rack, and is more suitable for items with relatively large vertical dimensions.

[0058] The following further describes the present utility model in detail with reference to the embodiments accompanied by drawings.

[0059] Embodiment 1

[0060] As Figures 1 - 19 shown, the dishwasher of this preferred embodiment is used for washing tableware and / or fruits and vegetables. The tableware includes bowls, dishes, cookware, etc. The dishwasher includes a box body 1, a bowl rack assembly, and a water flow system. The box body 1 has an inner cavity 10 with an open top or side. In this embodiment, the inner cavity 10 has an open top, and a part of the inner cavity 10 of the box body 1 serves as a storage space.

[0061] The bowl rack assembly is arranged in the inner cavity 10 of the box body 1. The bowl rack assembly includes a shelf 2 and a bowl rack 3. The bowl rack 3 can be placed on the bottom wall of the inner cavity 10 or moved out from the inner cavity 10. In this embodiment, the shelf 2 and the bowl rack 3 can not only place tableware such as bowls and dishes, but also place cookware, fruits and vegetables, etc.

[0062] The shelf 2 can be switched between a first position and a second position. As Figure 2 shown, when the shelf 2 is in the first position, the shelf 2 is horizontally located above the bowl rack 3. At this time, tableware can be placed on both the shelf 2 and the bowl rack 3. As Figure 16 shown, when the shelf 2 is in the second position, the shelf 2 is vertically stored in the storage space. The storage space is located on one side of the bowl rack 3. When the shelf 2 is not in use, it does not need to be taken out of the box body 1, and there is no need to prepare a space outside the box body 1 for placing the shelf 2 and the spray assembly.

[0063] The shelf 2 can be manually moved to the first position or the second position. There is no connection relationship between the shelf 2 and the bowl rack 3 and the box body 1. In this embodiment, the dishwasher further includes a connecting piece 31 that can be located in the box body 1. The shelf 2 is connected to the connecting piece 31. The connecting piece 31 is in the shape of a rod with an axis extending horizontally. The shelf 2 can rotate around the axis of the connecting piece 31 to a horizontal state or a vertical state, and the shelf 2 can move up and down relative to the connecting piece 31 to one side of the bowl rack 3 or above the bowl rack 3 when in the vertical state. That is, the shelf 2 rotates around the connecting piece 31 to a horizontal state or a vertical state, and the shelf 2 can move up and down relative to the connecting piece 31 to one side of the bowl rack 3 or above the bowl rack 3 when in the vertical state.

[0064] When the shelf 2 is switched from the first position to the second position, first rotate the shelf 2 upward to the vertical state, and then move the shelf 2 downward until the shelf 2 is located beside the bowl rack 3. When the shelf 2 is switched from the second position to the first position, first move the shelf 2 upward to the top of the bowl rack 3, and then rotate the shelf 2 downward to the horizontal state.

[0065] As can be seen from the moving process of the shelf 2, there will be no problem of component interference and jamming when switching between the horizontal and vertical directions. The moving process of the shelf 2 can proceed smoothly, and the top of the inner cavity 10 is open, providing sufficient space for the shelf 2 to flip up and down.

[0066] In addition, the flipping form of the shelf 2 of the present utility model enables the size of the shelf 2 to be made larger, and it can even cover the entire open top of the bowl rack 3, capable of placing a relatively large number of tableware. In this embodiment, when the shelf 2 is in the first position, the vertical projection of the shelf 2 falls within the vertical projection of the bowl rack 3, and the area of the vertical projection of the shelf 2 accounts for 90%-98% of the area of the vertical projection of the bowl rack 3. The shelf 2 has a relatively large area and can hold a relatively large number of tableware.

[0067] As Figure 2 、 5 、shown in Figure 6, the axis of the connecting member 31 extends in the left-right direction, and at this time the shelf 2 flips forward and backward; of course, it can also be that the axis of the connecting member 31 extends in the front-back direction, and at this time the shelf 2 flips left and right, but it is not as convenient as flipping forward and backward.

[0068] The dishwasher further includes a guide rail 24 that can be located in the cabinet 1. One end of the connecting member 31 extends into the guide rail 24. When the shelf 2 is in the vertical state, the guide rail 24 extends vertically and slidably cooperates with the connecting member 31 to guide the vertical movement of the shelf 2. In this embodiment, the guide rail 24 is provided on the shelf 2. A circular frame bar is provided at the bottom of the shelf 2, and the area inside the frame bar is the guide rail 24, with a simple structure. A fixing member 35 is fixedly installed on the bowl rack 3, and the connecting member 31 is fixedly installed on the fixing member 35, so that the connecting member 31 is relatively fixedly installed on the top of the bowl rack 3. Of course, the connecting member 31 can also be fixedly installed on the side wall 1 of the cabinet 1.

[0069] In addition, a groove 310 for embedding the guide rail 24 is provided on the peripheral wall of the connecting member 31 to prevent the guide rail 24 and the connecting member 31 from separating. As Figure 7 shown, the cross-section of the connecting member 31 can be circular, or, as Figure 5 、 6 shown, the connecting member 31 includes a shaft 311 and a roller 312 rotatably sleeved on the shaft, and the cross-section of the roller 312 is elliptical.

[0070] When the shelf 2 is in the first position, the guide rail 24 extends in the front-rear direction, and the shelf 2 is supported on the bowl rack 3 to improve the stability of the shelf. In this embodiment, a support portion 33 is provided at the top of the bowl rack 3. When the shelf 2 is in the first position, the shelf 2 is supported on the support portion 33, and the support portion 33 inclines upward from bottom to the central part of the bowl rack 3. When the shelf 2 is switched from the second position to the first position, the support portion 33 guides the guide rail 24, so that the shelf 2 horizontally covers above the bowl rack 3. Also, the support portion 33 is U-shaped, and both ends are installed on the bowl rack 3. The support portion 33 is used as a handle.

[0071] In this embodiment, the form of the rear flip of the shelf 2 is adopted: when the shelf 2 is in the first position, the connecting member 31 is adjacent to the rear end of the guide rail 24, so that the shelf 2 flips backward. When the shelf 2 is in the second position, the shelf 2 is located between the bowl rack 3 and the rear wall surface of the inner cavity 10 and flips backward, which is more in line with ergonomics and is more convenient to operate; and in this state, the connecting member 31 is lower than the highest point of the shelf 2, so that when the shelf 2 is in the first position, there is enough space above it to place items; in this state, the connecting member 31 is located in the upper part of the guide rail 24 to prevent the upper part of the shelf 2 from shaking.

[0072] Guide rails 24 are provided on both opposite sides (left and right sides) of the shelf 2. Correspondingly, there are two connecting members 31, so that the shelf 2 is evenly stressed when moving. The shelf 2 and the guide rail 24 together form a U-shaped structure. The ratio of the length l to the height h of the U-shaped structure is between 0.13 and 0.16. The U-shaped structure is thinner and occupies less space in the thickness direction. The cross-section of the bowl rack 3 is square, and the connecting member 31 is arranged adjacent to the corner of the bowl rack 3 to facilitate the shelf 2 to flip to the side of the bowl rack 3.

[0073] As Figure 14 shown, the horizontal plane where the center line of the connecting member 31 is located is called the horizontal dividing line a, the vertical plane where the center line of the connecting member 31 is located is called the longitudinal dividing line b, the horizontal distance between the longitudinal dividing line b and the rear wall surface of the inner cavity 10 is called L1, the horizontal distance between the longitudinal dividing line b and the rearmost part when the shelf 2 is in the first position state is called L2, and the vertical distance between the horizontal dividing line a and the highest point when the shelf 2 is in the first position state is called L4. L1≥L4, L1≥L2, so that the shelf 2 has enough storage space and installation clearance before and after flipping. L4 / L2=(0.8~1.2), so that when the shelf 2 is in the first position, there is a large enough area to place items.

[0074] As Figure 10As shown, partial upwardly arched retaining ribs 27 can be provided at the corners of the shelf 2. A limiting opening 271 for limiting tableware is formed between the retaining ribs 27 and the shelf 2. For some tableware, such as the rim of the pot body of a pot, it can be buckled in the limiting opening 271, and the retaining ribs 27 abut against the outer peripheral wall of the pot body. In this case, as Figure 14 shown, the straight-line distance between the center line of the connecting member 31 and the rearmost part of the shelf 2 in the first position state is called L3, and L1 ≥ L3 to prevent interference between the retaining ribs 27 and the box body 1 when the shelf 2 flips.

[0075] When the height H of the inner cavity 10 of the box body 1 is fixed, in order to improve the space utilization rate of the inner cavity 10 of the box body 1 and achieve large-set cleaning, the height of the bowl rack 3 is L5, and L4 / L5 ≤ 0.25. The height of the inner cavity 10 is H, 50% ≤ L5 / H ≤ 80% to leave space for the shelf 2 and the items placed thereon; 60% ≤ (L4 + L5) / H ≤ 90%, so that space is reserved above the shelf 2 when the shelf 2 is in the first position, and it can accommodate some tableware or fruits and vegetables with a height exceeding L4.

[0076] In this embodiment, as Figure 19 shown, the top of the bowl rack 3 is open to form a first opening 301, and the side of the bowl rack 3 is open to form a second opening 302. Of course, the second opening 302 may not be provided on the side of the bowl rack 3. When the shelf 2 is in the first position, the shelf 2 horizontally extends and covers the first opening 301. When the shelf 2 is in the second position, the shelf 2 vertically extends and covers the second opening 302.

[0077] Here, it should be noted that the bowl rack assembly of this embodiment can be used not only in dishwashers but also in other household appliances, such as disinfection cabinets.

[0078] As Figure 8 、 9 shown, the water flow system includes a water supply pipe 4 and a spraying assembly. An outlet 41 is provided on the water supply pipe 4. In this embodiment, the water supply pipe 4 is entirely located in the inner cavity 10 of the box body 1 and at its rear part. It is also possible to make part of the water supply pipe 4 located outside the box body 1, but the outlet 41 is located in the inner cavity 10 of the box body 1. The water flow system further includes a water pumping mechanism for supplying water to the water supply pipe 4, and the water pumping mechanism can adopt an existing structure.

[0079] The spraying assembly includes a water passing pipe 22 for conveying water flow and spraying holes for spraying the water in the water passing pipe 22. The spraying holes are provided on the water passing pipe 22; alternatively, the spraying assembly further includes a first spraying member 21 in fluid communication with the water passing pipe 22, and the spraying holes are provided on the first spraying member 21.

[0080] The first spraying member 21 of this embodiment is strip-shaped, and its extending direction is the same as that of the water passing pipe 22. AsFigure 17 As shown, the bowl rack 3 is provided with an avoidance opening 301 for avoiding the spraying assembly. When the shelf 2 is in the second position, the spraying assembly passes downward through the avoidance opening 301. The shelf 2 and the guide rail 24 as a whole form a U-shaped structure, and the spraying assembly is located in the U-shaped area of the U-shaped structure, and a part of the bowl rack 3 is surrounded by the U-shaped area.

[0081] As Figure 2 、 8 shown, when the shelf 2 is in the first position, the water pipe 22 extends horizontally, and the water pipe 22 is docked with and in fluid communication with the water outlet 41; as Figure 16 、 17 shown, when the shelf 2 is in the second position, the water pipe 22 extends vertically, and the water pipe 22 is disengaged from and in fluid disconnection with the water outlet 41. The shelf 2 and the spraying assembly of the water flow system are both located between the bowl rack 3 and the rear wall surface of the inner cavity 10, that is, the shelf 2 and the spraying assembly are both located at the rear of the inner cavity 10 and the rear side of the bowl rack 3, and the spraying assembly is located on the side of the shelf 2 facing the bowl rack 3.

[0082] In this embodiment, the guide rail 24 extends straight, and the connecting piece 31 is located obliquely below the water outlet 41 of the water supply pipe 4. During the flipping process of the shelf 2, interference is likely to occur between the water pipe 22 and the water supply pipe 4, affecting the flipping of the shelf 2. Therefore, to solve this problem, when the shelf 2 is in the first position, the water pipe 22 can move relative to the shelf 2 in the front-rear direction. As Figure 3 shown, a positioning member 221 is provided on the outer peripheral wall of the water pipe 22. The positioning member 221 has a positioning groove 222 extending along the length direction of the water pipe 22. A positioning portion 25 is provided on the shelf 2 and is constrained in the positioning groove 222. Relative displacement can occur between the positioning groove 222 and the positioning portion 25, and the positioning portion 25 is always located in the positioning groove 222.

[0083] In addition, as Figure 9 shown, a convex portion 42 is provided on the front side wall of the water supply pipe 4, and the water outlet 41 is provided on the convex portion 42. The wall surface of the convex portion 42 is a first inclined surface 421 that slopes backward from top to bottom. The wall surface of the water inlet end of the water pipe 22 is a second inclined surface 223 that can be in inclined surface fit with the first inclined surface 421. When the water pipe 22 flips downward from the water outlet 41, due to the extrusion of the first inclined surface 421, the water pipe 22 will move forward. When the water pipe 22 is in a vertical state, under the action of gravity, the positioning portion 25 abuts against the top wall of the positioning groove 222 (the rear end when the water pipe 22 is in a horizontal state); when the water pipe 22 flips upward towards the water outlet 41, due to the extrusion of the first inclined surface 421, the water pipe 22 will move forward, so that the water inlet end of the water pipe 22 is smoothly docked with the water outlet 41.

[0084] Regarding the connection between the shelf 2 and the water pipe 22, in this embodiment, the positioning member 221 is arranged at a position close to the water outlet end of the water pipe 22. In this way, when the shelf 2 is in the first position, since there is no positioning at the water inlet end of the water pipe 22, it is likely to sag under the action of gravity, affecting the alignment and connection between the water inlet end of the water pipe 22 and the water outlet 41. Therefore, as Figure 4 shown, the shelf 2 is provided with a placement portion 20. When the water pipe 22 corresponds to the water outlet 41, the portion of the water pipe 22 adjacent to the water inlet end is placed on the placement portion 20, so that the water pipe 22 is positioned in the up and down direction.

[0085] A vertically extending slideway 43 is provided on the water supply pipe 4. The water outlet 41 is located in the slideway 43 or at the end of the slideway 43. The water inlet end of the water pipe 22 can slide along the slideway 43. The slideway 43 is in the shape of a flared opening that tapers in the direction in which the water pipe 22 moves to the water outlet 41.

[0086] In this embodiment, as Figures 11 - 13 shown, two vertically extending guide bars 44 are symmetrically provided on the left and right sides of the water outlet 41. The area between the two guide bars 44 is the slideway 43. Each guide bar 44 is inclined towards the water outlet 41 in the direction in which the water pipe 22 moves to the water outlet 41, so as to form a flared slideway 43. Each guide bar 44 includes a downstream section 441 and an upstream section 442 that are sequentially arranged and connected in the direction in which the water pipe 22 moves to the water outlet 41. The inclination angle of the downstream section 441 is greater than that of the upstream section 442.

[0087] Two guide blocks 224 are symmetrically provided on the outer peripheral wall of the water inlet end of the water pipe 22. Guide grooves 443 are provided on the side wall of the slideway 43 (i.e., the guide bar 44) along its length direction. The guide blocks 224 slide correspondingly along the guide grooves 443 of one guide bar 44. Along the direction in which the water pipe 22 moves to the water outlet 41, the width of the guide groove 443 gradually becomes smaller, facilitating the guide blocks 224 to enter the guide grooves 443. When the water pipe 22 corresponds to the water outlet 41, the guide blocks 224 are positioned relative to the guide grooves 443 in the front and back directions. The guide blocks 224 in this embodiment are in a V shape, including a first part 2241 and a second part 2242. The included angle between the first part 2241 and the second part 2242 is an obtuse angle, and the positioning effect with the guide groove 443 is good.

[0088] As Figure 17 、 18 shown, a second spraying member 32 is provided in the box body 1. The second spraying member 32 can adopt an existing spraying arm structure and can rotate around its axis in the box body 1. The spray nozzles of the second spraying member 32 face the bowl rack 3.

[0089] The second spray member 32 is located below the bowl rack 3. A resting platform 45 is provided at the lower part of the water supply pipe 4, and the resting platform 45 is located above the second spray member 32. When the shelf 2 is in the second position, the bottom of the water passing pipe 22 rests on the resting platform 45, preventing the water passing pipe 22 from being in a vertical state when the shelf 2 is in the second position and interfering with the rotation of the second spray member 32. The shelf 2 is provided with a first limiting portion 26, and the bowl rack 3 is provided with a second limiting portion 34. When the shelf 2 is in the second position, the first limiting portion 26 presses against the second limiting portion 34, and the shelf 2 is located above the second spray member 32, preventing the shelf 2 from interfering with the rotation of the second spray member 32 when in the second position. The bowl rack 3 is a hollow structure composed of multiple ribs, and the second limiting portion 34 is one of the ribs of the bowl rack 3.

[0090] Regarding the water outlet 41, as Figure 11 , 12 shown, the orientation of the water outlet 41 can be inclined or horizontal. In this embodiment, the orientation of the water outlet 41 is inclined, with an angle of about 25° with the horizontal plane. When the shelf 2 is in the second position state, the water outlet 41 can be in a closed state or an open state. Here, the closed state means that water cannot flow out of the water outlet 41, and the open state means that water can flow out of the water outlet 41.

[0091] In other words, the water outlet 41 has two working states: in the first working state, the water inlet end of the water passing pipe 22 is connected and communicated with the water outlet 41 of the water supply pipe 4, that is, the water outlet 41 is connected with the spray assembly and supplies water to it, and the water sprayed by the spray assembly is used to clean the items in the cleaning machine; in the second working state, the water inlet end of the water passing pipe 22 is separated from the water outlet 41 of the water supply pipe 4, that is, the water outlet 41 is disconnected from the spray assembly, and the water outlet 41 is used as a spray port to spray the items in the cleaning machine, that is, the water outlet 41 can still supply water and flow out. At this time, as a spray port, it sprays the items in the cleaning machine. Because the orientation of the water outlet 41 is fixed after being manufactured, it can perform local enhanced cleaning on the items at specific parts. In this embodiment, the water inlet end of the water passing pipe 22 is connected and communicated with the water outlet 41 of the water supply pipe 4 in the horizontal direction, or the water inlet end of the water passing pipe 22 can also be connected and communicated with the water outlet 41 of the water supply pipe 4 in the vertical direction.

[0092] Because the spray holes of the spray assembly in this embodiment face the shelf 2, when the water outlet 41 is in the first working state, the shelf 2 is located on the water spraying path of the spray assembly; and when the water outlet 41 is in the second working state, the bowl rack 3 is located on the water flow path of the water outlet 41. The water outlet 41 sprays from top to bottom, and the second spray member 32 sprays from bottom to top, and the two cooperate to achieve a good cleaning effect on the tableware in the bowl rack 3.

[0093] The water outlet 41 is provided with partition ribs 411, thereby partitioning the water outlet 41 into a plurality of water outlet holes 412. Different water outlet holes 412 clean different areas of the bowl rack 3, and at least two of the water outlet holes 412 have different orientations.

[0094] As can be seen from the above, whether the shelf 2 is in the first position or the second position, the shelf 2 and the spraying assembly are both located in the inner cavity 10 of the box body 1.

[0095] Embodiment 2

[0096] The difference between this embodiment and Embodiment 1 lies in the different structure of the guide rail 24, and the rest can refer to Embodiment 1.

[0097] As Figures 20 - 23 shown, the height where the connecting member 31 is located is the same as the height where the water outlet 41 is located. The guide rail 24 includes a straight section 241 extending straight and an inclined section 242 extending obliquely. When the shelf 2 is in the first position, the front end of the inclined section 242 is connected to the rear end of the straight section 241. The straight section 241 extends in the front-rear direction, and the inclined section 242 slopes upward from front to back. The connecting member 31 extends into the inclined section 242. In this structural form of the guide rail 24, when the shelf 2 is flipped, there will be no interference between the water pipe 22 and the water supply pipe 4.

[0098] Embodiment 3

[0099] The differences between this embodiment and Embodiment 1 are as follows: 1. This embodiment adopts the form of the front flip of the shelf 2:

[0100] When the shelf 2 is in the first position, the connecting member 31 is adjacent to the front end of the guide rail 24. When the shelf 2 is in the second position, the shelf 2 and the spraying assembly are both located between the bowl rack 3 and the front wall surface of the inner cavity 10, that is, the shelf 2 and the spraying assembly are both located in the front part of the inner cavity 10, at the front side of the bowl rack 3. In this case, the shelf 2 is flipped forward. Since the water supply pipe 4 is generally arranged at the rear of the box body 1, flipping the shelf 2 to the front side will not make the rear part of the box body 1 too crowded; in addition, flipping the shelf 2 to the front side will not affect the user's vision and the tableware placement experience. In this scheme, the guide rail 24 extends straight, and the connecting member 31 is located obliquely below the water outlet 41 of the water supply pipe 4. When the shelf 2 is flipped forward, there will be no problem of interference between the water pipe 22 and the water supply pipe 4.

[0101] 2. The shelf 2 in this embodiment is not supported on the support portion 33, but when the shelf 2 is in the first position, the guide rail 24 is supported on the top of the bowl rack 3, so that the shelf 2 is supported on the bowl rack 3. The guide rail 24 extends in the front-rear direction and has a large contact area with the bowl rack 3, so that the stability of the shelf 2 is good.

[0102] The "horizontal" mentioned above includes the straight extension of a component in the horizontal direction, that is, the two ends of the component are on the same horizontal plane, but it is not limited to this direction. As long as the overall extension direction of the component is in the horizontal direction, for example, the component extends along the front-back or left-right direction, but the two ends of the component are not on the same horizontal plane; similarly, the "vertical" includes the straight extension of a component in the vertical direction, that is, the two ends of the component are on the same plumb plane, but it is not limited to this direction. As long as the overall extension direction of the component is in the vertical direction, for example, the component extends along the up-down direction, but the two ends of the component are not on the same plumb plane.

[0103] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "horizontal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the disclosed embodiments of the present utility model can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.

[0104] The "fluid communication" referred to in the present utility model refers to the spatial position relationship between two components or parts (hereinafter uniformly referred to as the first part and the second part respectively), that is, fluid (gas, liquid or a mixture of both) can flow or / and be transported from the first part along the flow path to the second part. It can be that the first part and the second part are directly connected, or it can be that the first part and the second part are indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, a passage, a conduit, a flow guide, a hole, a groove, etc., or a chamber allowing fluid to flow through or a combination of the above.
