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 water pipe of the upper spray arm 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 is connected to the water supply pipe located on the side wall of the washing chamber, so as to transport the washing water from bottom to top. Because the height of the bowl basket may need to be adjusted 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, a movable connection is required between the spray arm and the water supply pipe.

[0003] For example, the Chinese utility model patent with patent number CN201820365541.8 (publication number CN209252763U) discloses a spray arm pipe connection structure and a dishwasher. The connection structure includes a movable component for being arranged on the bowl basket and a fixed component for being arranged on the side wall of the dishwashing tank. The movable component includes a water outlet pipe and a movable joint arranged at one end of the water outlet pipe, and the movable joint has a first inclined surface; the fixed joint has a second inclined surface and a water inlet channel, and the water inlet channel is connected to the axial direction of the water outlet pipe. The movable joint and the fixed joint are connected by a plug-in structure. When the plug-in structure is plugged in, the first inclined surface and the second inclined surface cooperate, and the water outlet pipe is connected to the water inlet channel. When the user lifts the bowl basket vertically out of the dishwashing tank, the movable component is lifted out together with the bowl basket. When the user places the bowl basket, the socket in the movable component will buckle the plug column in the fixed component, and the movable joint and the fixed joint are in contact in the form of an inclined surface, which can reduce user misoperation and make the pipe connection good.

[0004] This method is suitable for the bowl basket to be lifted out vertically or placed into the bowl sink, because the pipe connection structure is arranged on the bowl basket, so the pipe connection structure is also lifted out vertically or placed into the sink in the same way.

[0005] Alternatively, as shown in the "Water Distribution Structure, Internal Water Pipe Structure and Dishwasher" disclosed in the Chinese utility model patent with patent number CN202121506706.7 (publication number CN215191361U), a water outlet is provided on the side wall of the water outlet end of the inner water pipe, and the water distribution structure includes: a ball storage tank, which is arranged on the inner water pipe and located above the water outlet, and the outer side of the ball storage tank is a closed structure; a water distribution ball is configured to be able to move between the ball storage tank and the water outlet, and can move from the position of the water outlet to the ball storage tank under the action of water pressure, and move from the ball storage tank to the water outlet when the water pressure at the water outlet drops, and close the water outlet under the action of water pressure.

[0006] This method is only applicable to the horizontal connection between the water pipe joint and the inner water pipe.

[0007] It can be seen from the above that the current connection method of the water pipe joint connected to the spray arm and the inner water pipe is either to connect with the inner water pipe after moving in the vertical direction, or to connect with the inner water pipe after moving in the horizontal direction. In the aforementioned method, the spray arm connecting pipe connected to the bowl rack is moved outside the tank body, which requires a special space for placing the bowl rack, and the spray arm connecting pipe connected to the bowl rack is also located outside the tank body, which is inconvenient. Utility Model Content

[0008] The technical problem to be solved by the utility model is to provide a cleaning machine in which a spray assembly can be placed in a box when not in use, in view of the current status of the prior art.

[0009] The utility model solves the above technical problems by adopting the following technical solution: a cleaning machine comprising

[0010] A box body having an inner cavity with an open top or side;

[0011] a water supply pipe having a water outlet thereon;

[0012] A spray assembly capable of being fluidly connected to or disconnected from the water outlet;

[0013] The invention is characterized in that when the spray assembly is in fluid communication with the water outlet or is fluid disconnected from the water outlet, the spray assembly is located in the inner cavity of the box body.

[0014] In the above scheme, the spray assembly includes a water pipe for conveying water flow and a spray hole for spraying water in the water pipe. The water pipe can be connected with the water outlet and fluidically connected. In this state, the water pipe extends horizontally. The water pipe is detached from the water outlet and the fluid is disconnected. In this state, the water pipe extends vertically.

[0015] In order to make the water pipe dock or detach from the water outlet, the cleaning machine also includes

[0016] The connecting piece is in the shape of a rod with an axis extending in a horizontal direction, and the connecting piece can be located in the box body;

[0017] The mounting piece is provided for the water pipe to be mounted on it, the extension direction of the mounting piece is consistent with the extension direction of the water pipe, the mounting piece is rotatably connected with the connecting piece, and the mounting piece can rotate around the axis of the connecting piece to a horizontal state or a vertical state, and the mounting piece can move up and down relative to the connecting piece in a vertical state and is located in the inner cavity of the box. The utility model mounts the water pipe on the mounting piece by arranging the mounting piece, the mounting piece can rotate relative to the rotating shaft to a horizontal state or a vertical state, and the mounting piece can move in the vertical direction, and the water pipe moves synchronously during the movement of the mounting piece, docking with or detaching from the water outlet, and the movement mode is novel.

[0018] In the above scheme, the axis of the connecting member extends in the left-right direction, and the mounting member flips forward and backward; or, the axis of the connecting member extends in the front-back direction, and the mounting member flips left and right.

[0019] In order to guide the vertical movement trajectory of the mounting piece, a guide rail is provided on the mounting piece, and one end of the connecting piece extends into the guide rail. When the mounting piece is in a vertical state, the guide rail extends vertically and slides with the connecting piece. When the mounting piece is in a horizontal state, the guide rail is also in a horizontal state to play a guiding role.

[0020] Preferably, guide rails are provided on opposite sides of the mounting member, and correspondingly, there are two connecting members, so that the mounting member is evenly stressed when moving.

[0021] Preferably, the axis of the connecting member extends in the left-right direction, and when the mounting member is in the first position, the guide rail extends in the front-back direction. In this way, the mounting member flips forward and backward when flipping, which is convenient for users to operate compared to flipping left and right.

[0022] When the mounting piece is in the second position, one form is that the mounting piece is flipped over to the front of the inner cavity: when the mounting piece is in the first position, the connector is adjacent to the front end of the guide rail, and when the mounting piece is in the second position, the mounting piece and the spray assembly are both at the front of the inner cavity. In this case, the mounting piece flips forward, because the water supply pipe is generally arranged at the rear of the box, flipping the mounting piece to the front side will not make the rear of the box too crowded; in addition, flipping the mounting piece to the front side will not affect the user's vision and tableware placement experience. In this solution, the guide rail extends straight, and the connector is located obliquely below the water outlet of the water supply pipe. In this case, the guide rail extends straight, and the connector is located obliquely below the water outlet of the water supply pipe.

[0023] When the mounting member is in the second position, one form is that the mounting member is flipped to the rear of the inner cavity: when the mounting member is in the first position, the connecting member is adjacent to the rear end of the guide rail, and when the mounting member is in the second position, the mounting member and the spray assembly are both located at the rear of the inner cavity. Flipping backwards is more in line with ergonomics and is more convenient to operate.

[0024] In the scheme where the mounting piece is turned back, the structure of the guide rail is as follows: the guide rail extends straight, and the connecting piece is located obliquely below the water outlet of the water supply pipe.

[0025] During the turning over of the mounting member, interference between the water pipe and the water supply pipe is likely to occur, affecting the turning over of the mounting member. Therefore, when the mounting member is in the first position, the water pipe can move relative to the mounting member in the front-rear direction.

[0026] Preferably, a positioning member is provided on the outer peripheral wall of the water pipe, the positioning member has a positioning groove extending along the length direction of the water pipe, and the mounting member is provided with a positioning portion constrained in the positioning groove, and relative displacement can occur between the positioning groove and the positioning portion, and the positioning portion is always located in the positioning groove;

[0027] Alternatively, a positioning member is provided on the mounting member, the positioning member has a positioning groove extending along the length direction of the water pipe, a positioning portion constrained in the positioning groove is provided on the outer peripheral wall of the water pipe, relative displacement can occur between the positioning groove and the positioning portion, and the positioning portion is always located in the positioning groove. The cooperation between the positioning member and the positioning portion enables the water pipe to be always connected to the mounting member, and the water pipe can move relative to the mounting member along its length direction. The mounting member is a hollow structure composed of frame strips, and the positioning portion is the frame strip.

[0028] In order to make the water pipe move forward and backward relative to the water supply pipe when the water pipe interferes with the water supply pipe, and eliminate the interference between the two, a convex portion is provided on the outer wall of the water supply pipe, and the water outlet is provided on the convex portion, and the wall surface of the convex portion is a first inclined surface that tilts backward from top to bottom, and the wall surface of the water inlet end of the water pipe is a second inclined surface that can be inclined with the first inclined surface. When the water pipe flips downward from the water outlet, the water pipe will move forward due to the squeezing of the first inclined surface. When the water pipe is in a vertical state, under the action of gravity, the positioning portion and the top wall of the positioning groove (the rear end of the water pipe when it is in a horizontal state) are against each other; when the water pipe flips upward toward the water outlet, the water pipe will move forward due to the squeezing of the first inclined surface, so that the water inlet end of the water pipe and the water outlet are smoothly docked. The angle between the first inclined surface and the plumb plane is about 10°, so that when the water pipe flips, the interference amount of tan10° is reduced, achieving the effect of smooth flipping.

[0029] In order to guide the water pipe and facilitate the alignment of the water inlet end of the water pipe with the water outlet, a vertically extending slide is provided on the water supply pipe, and the water outlet is located in the slide or at the end of the slide. The water inlet end of the water pipe can slide along the slide to guide the water pipe, so as to improve the accuracy of the connection between the water pipe and the water outlet.

[0030] Preferably, the slide is in a trumpet shape that decreases in diameter along the direction where the water pipe moves to the water outlet, so that the water pipe can smoothly enter the slide. When the water pipe corresponds to the water outlet, the water pipe is positioned relative to the slide in the left and right direction.

[0031] Preferably, two vertically extending guide bars are symmetrically provided on the left and right sides of the water outlet, and the area between the two guide bars is the slideway. Each guide bar moves along the water pipe to the water outlet and tilts toward the water outlet to form a trumpet-shaped slideway.

[0032] Preferably, each guide strip comprises a downstream section and an upstream section which are sequentially arranged and connected along the direction of the water pipe moving to the water outlet, and the inclination angle of the downstream section is greater than the inclination angle of the upstream section, which further facilitates the water pipe to enter the slide.

[0033] Preferably, two guide blocks are symmetrically provided on the outer peripheral wall of the water inlet end of the water pipe, and a guide groove is provided on the side wall of the slide along its length direction, and the guide block slides along the guide groove of a guide strip; along the direction of the water pipe moving to the water outlet, the width of the guide groove gradually decreases, so that the guide block can enter the guide groove easily, and when the water pipe corresponds to the water outlet, the guide block is positioned relative to the guide groove in the front-to-back direction.

[0034] Preferably, the mounting member is in a horizontal state, and the mounting member can be used for placing tableware and / or fruits and vegetables and / or pots. The mounting member can not only be used for the water pipe to be installed on it, and drive the water pipe to move to connect or disconnect with the water inlet, but also can be used as a shelf for placing tableware and / or fruits and vegetables.

[0035] Compared with the prior art, the utility model has the following advantages: the utility model ensures that when the water pipe is connected to or disconnected from the water outlet on the water supply pipe, the water pipe is located in the inner cavity of the box, so there is no need to prepare a special placement space outside the box for the water pipe when not in use, which can save space.

[0061] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0062] Example 1

[0063] like Figures 1 to 19 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, etc. The washing machine includes a box 1, a bowl rack assembly and a water flow system. The box 1 has an inner cavity 10 with a top or side open. The inner cavity 10 of this embodiment is open at the top, and a part of the inner cavity 10 of the box 1 is used as a storage space.

[0064] The bowl rack assembly is arranged in the inner cavity 10 of the box body 1, and 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 removed from the inner cavity 10. The shelf 2 and the bowl rack 3 of this embodiment can not only place tableware such as bowls and plates, but also pots, fruits and vegetables, etc.

[0065] The shelf 2 can be switched between a first position and a second position. Figure 2 As shown, when the shelf 2 is in the first position, the shelf 2 is horizontally located above the bowl rack 3, and tableware can be placed on both the shelf 2 and the bowl rack 3; Fig.16 As shown, when the shelf 2 is in the second position, the shelf 2 is vertically stored in the storage space, and the storage space is located on one side of the bowl rack 3. The shelf 2 does not need to be taken out of the box 1 when not in use, and there is no need to prepare space outside the box 1 for placing the shelf 2 and the spray assembly.

[0066] The shelf 2 can be manually moved to the first position or the second position. There is no connection between the shelf 2 and the dish rack 3 or the box 1. In this embodiment, the washing machine also includes a connecting member 31 that can be located in the box 1. The shelf 2 is connected to the connecting member 31. The connecting member 31 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 31 to a horizontal state or a vertical state, and the shelf 2 can move up and down relative to the connecting member 31 to one side of the dish rack 3 or above the dish rack 3 when it is in the vertical state. That is, the shelf 2 rotates to a horizontal state or a vertical state with the connecting member 31 as the axis, and the shelf 2 can move up and down relative to the connecting member 31 to one side of the dish rack 3 or above the dish rack 3 when it is in the vertical state.

[0067] When the shelf 2 is switched from the first position to the second position, the shelf 2 is first rotated upward to a vertical state, and then the shelf 2 is moved downward until the shelf 2 is located next to the bowl rack 3. When the shelf 2 is switched from the second position to the first position, the shelf 2 is first moved upward to the top of the bowl rack 3, and then the shelf 2 is rotated downward to a horizontal state.

[0068] It can be seen from the movement process of the shelf 2 that there will be no problem of component interference and jamming when switching between horizontal and vertical directions. The movement process of the shelf 2 can proceed smoothly, and the top of the inner cavity 10 is open, so that there is enough space for the shelf 2 to turn upside down.

[0069] In addition, the flipping form of the shelf 2 of the utility model can make the size of the shelf 2 larger, and can even cover the top opening of the bowl rack 3, so that a large number of tableware can be placed. 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 vertical projection area of ​​the shelf 2 accounts for 90%-98% of the vertical projection area of ​​the bowl rack 3. The area of ​​the shelf 2 is large, and a large number of tableware can be placed.

[0070] like Figure 2 , 5 As shown in 6, the axis of the connecting member 31 extends along the left-right direction, and the shelf 2 is flipped forward and backward; of course, it is also possible that the axis of the connecting member 31 extends along the front-back direction, and the shelf 2 is flipped left-right, but not as convenient as flipping forward and backward.

[0071] The cleaning machine also includes a guide rail 24 that can be located in the box body 1, and one end of the connecting member 31 extends into the guide rail 24. When the shelf 2 is in a 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.

[0072] In this embodiment, the guide rail 24 is arranged on the shelf 2, and an annular frame bar is arranged at the bottom of the shelf 2. The area inside the frame bar is the guide rail 24, and the structure is simple.

[0073] A fixing member 35 is fixedly mounted on the bowl rack 3 , and the connecting member 31 is fixedly mounted on the fixing member 35 , so that the connecting member 31 is relatively fixedly mounted on the top of the bowl rack 3 . Of course, the connecting member 31 can also be fixedly mounted on the side wall 1 of the box body 1 .

[0074] In addition, a circle of embedding grooves 310 for the guide rail 24 to be embedded in the peripheral wall of the connecting member 31 is provided to prevent the guide rail 24 and the connecting member 31 from being separated. Figure 7 As shown, the cross section of the connecting member 31 may be circular, or, as shown in FIG. Figure 5 , 6 As 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.

[0075] Of course, it is also feasible to arrange the guide rail 24 on the dish rack 3 . In this case, the guide rail 24 extends vertically and the connecting member 31 is installed on the shelf 2 .

[0076] When the shelf 2 is in the first position, the guide rail 24 extends in the front-to-back 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 on 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 is inclined from bottom to top toward the central part of the bowl rack 3. When the shelf 2 switches from the second position to the first position, the support portion 33 guides the guide rail 24, so that the shelf 2 horizontally covers the top of the bowl rack 3. In addition, 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.

[0077] The present embodiment adopts the form of the shelf 2 flipping backward: 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 of the inner cavity 10, flipping backward, which is more in line with ergonomics and 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 at the upper part of the guide rail 24 to prevent the upper part of the shelf 2 from shaking.

[0078] The opposite sides (left and right sides) of the shelf 2 are provided with guide rails 24, and correspondingly, there are two connecting members 31, so that the shelf 2 is subjected to uniform force when moving. The shelf 2 and the guide rails 24 together form a U-shaped structure, and the ratio of the length l to the height h of the U-shaped structure is between 0.13-0.16. The U-shaped structure is relatively thin and occupies little space in the thickness direction.

[0079] The cross section of the dish rack 3 is square, and the connecting piece 31 is disposed near the corner of the dish rack 3 so as to facilitate the shelf 2 to flip to the side of the dish rack 3 .

[0080] like Fig.14 As shown, the horizontal plane where the center line of the connecting member 31 is located is called the horizontal dividing line a, the plumb line 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 of the inner cavity 10 is called L1, the horizontal distance between the longitudinal dividing line b and the rearmost part of the shelf 2 in the first position is called L2, and the vertical distance between the horizontal dividing line a and the highest point of the shelf 2 in the first position is called L4, L1≥L4, L1≥L2, so that the shelf 2 has sufficient storage space and installation clearance before and after flipping. L4 / L2=(0.8~1.2), so that the shelf 2 has a large enough area for placing items when it is in the first position.

[0081] like Fig.10 As shown, the corners of the shelf 2 can be provided with partially upwardly arched retaining ribs 27, and a limiting opening 271 for limiting the position of tableware is formed between the retaining ribs 27 and the shelf 2. For some tableware, such as the edge of a pot body of a pot, the retaining ribs 27 can be buckled in the limiting opening 271, and the retaining ribs 27 can be pressed against the outer peripheral wall of the pot body. In this case, Fig.14 As 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 is called L3, L1≥L3, to prevent the retaining rib 27 from interfering with the box body 1 when the shelf 2 is turned over.

[0082] When the height H of the inner cavity 10 of the housing 1 is fixed, in order to improve the space utilization of the inner cavity 10 of the housing 1 and realize a large number of washings, the height of the dish rack 3 is L5, and L4 / L5≤0.25.

[0083] The height of the inner cavity 10 is H, 50%≤L5 / H≤80%, leaving space for the shelf 2 and the items placed thereon; 60%≤(L4+L5) / H≤90%, thus reserving space above the shelf 2 when the shelf 2 is in the first position, which can accommodate some tableware or fruits and vegetables with a height exceeding L4.

[0084] In this embodiment, Fig.19 As 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 side of the bowl rack 3 may not be provided with the second opening 302. When the shelf 2 is in the first position, the shelf 2 extends horizontally and covers the first opening 301. When the shelf 2 is in the second position, the shelf 2 extends vertically and covers the second opening 302.

[0085] In this description, the bowl rack assembly of this embodiment can be used not only in a washing machine, but also in other household appliances, such as a disinfection cabinet.

[0086] like Figure 8 , 9 As shown, the water flow system includes a water supply pipe 4 and a spray assembly. The water supply pipe 4 is provided with a water outlet 41. In this embodiment, the water supply pipe 4 is entirely located in the inner cavity 10 of the box body 1 and at the rear thereof. The water supply pipe 4 may also be partially located outside the box body 1, but the water outlet 41 is located in the inner cavity 10 of the box body 1. The water flow system also includes a water pumping mechanism, which is used to supply water to the water supply pipe 4. The water pumping mechanism may adopt an existing structure.

[0087] The spray assembly is connected to the shelf 2 and can move with the shelf 2. When the shelf 2 is in the first position, the spray assembly is fluidly connected to the water outlet 41. When the shelf 2 is in the second position, the spray assembly is fluidly disconnected from the water outlet 41.

[0088] The spray assembly includes a water pipe 22 for conveying water flow and a spray hole for spraying water in the water pipe 22, and the spray hole is arranged on the water pipe 22; or, the spray assembly also includes a first spray piece 21 fluidly connected to the water pipe 22, and the spray hole is arranged on the first spray piece 21.

[0089] The first spraying member 21 of this embodiment is strip-shaped and extends in the same direction as the water pipe 22. Fig.17 As shown, the bowl rack 3 is provided with an avoidance opening 301 for avoiding the spray assembly. When the shelf 2 is in the second position, the spray assembly passes downward through the avoidance opening 301. The shelf 2 and the guide rail 24 form a U-shaped structure as a whole. The spray assembly is located in the U-shaped area of ​​the U-shaped structure, and the bowl rack 3 is partially surrounded by the U-shaped area.

[0090] The spray holes of this embodiment are toward the shelf 2, so as to clean the articles on the shelf 2. Of course, the spray holes may also be toward the bowl rack 3, or some of the spray holes may be toward the shelf 2, and some of the spray holes may be toward the bowl rack 3.

[0091] The water pipe 22 is installed on the shelf 2 , that is, the shelf 2 also serves as a mounting member for mounting the water pipe 22 , and the extending direction of the mounting member is consistent with the extending direction of the water pipe 22 .

[0092] like Figure 2 , 8 As shown, when the shelf 2 is in the first position, the water pipe 22 extends horizontally, and the water pipe 22 is connected to the water outlet 41 and fluidly communicated; Fig.16 , 17 As shown, when the shelf 2 is in the second position, the water pipe 22 extends vertically, and the water pipe 22 is detached from the water outlet 41 and the fluid is disconnected, and the shelf 2 and the spray component of the water system are both located between the bowl rack 3 and the rear wall of the inner cavity 10, that is, the shelf 2 and the spray component are both located at the rear of the inner cavity 10 and the rear side of the bowl rack 3, and the spray component is located on the side of the shelf 2 facing the bowl rack 3.

[0093] In this embodiment, 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. During the flipping process of the shelf 2, interference is easily generated between the water pipe 22 and the water supply pipe 4, affecting the flipping of the shelf 2. Therefore, in order 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.

[0094] like Figure 3As shown, a positioning member 221 is provided on the outer peripheral wall of the water pipe 22, and the positioning member 221 has a positioning groove 222 extending along the length direction of the water pipe 22. A positioning portion 25 constrained in the positioning groove 222 is provided on the shelf 2, and 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. The cooperation between the positioning member 221 and the positioning portion 25 enables the water pipe 22 to be always connected to the shelf 2, and the water pipe 22 can move relative to the shelf 2 along its length direction. The shelf 2 is a hollow structure composed of frame bars, and the positioning portion 25 is the frame bar.

[0095] Of course, it is also possible that a positioning piece 221 is provided on the shelf 2, and the positioning piece 221 has a positioning groove 222 extending along the length direction of the water pipe 22, and a positioning portion 25 constrained in the positioning groove 222 is provided on the outer peripheral wall of the water pipe 22, and relative displacement can be generated between the positioning groove 222 and the positioning portion 25, and the positioning portion 25 is always located in the positioning groove 222.

[0096] In addition, if Fig. 9 As 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, and the wall surface of the convex portion 42 is a first inclined surface 421 inclined backward from top to bottom, and the wall surface of the water inlet end of the water pipe 22 is a second inclined surface 223 that can be inclinedly matched with the first inclined surface 421. When the water pipe 22 turns downward from the water outlet 41, the water pipe 22 will move forward due to the squeezing of the first inclined surface 421, and when the water pipe 22 is in a vertical state, under the action of gravity, the positioning portion 25 and the top wall of the positioning groove 222 (the rear end of the water pipe 22 when it is in a horizontal state) are abutted; when the water pipe 22 turns upward toward the water outlet 41, the water pipe 22 will move forward due to the squeezing of the first inclined surface 421, so that the water inlet end of the water pipe 22 and the water outlet 41 are smoothly docked. The included angle between the first inclined surface 421 and the vertical plane is about 10°, so that when the water pipe 22 is turned over, the interference amount of tan10° is reduced, thereby achieving a smooth turning effect.

[0097] Regarding the connection between the shelf 2 and the water pipe 22, in this embodiment, the positioning member 221 is arranged near the water outlet end of the water pipe 22, so that when the shelf 2 is in the first position, the water inlet end of the water pipe 22 is not positioned and is easy 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. Figure 4 As shown, the shelf 2 has a placing 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 placing portion 20, so that the water pipe 22 is positioned in the up and down directions.

[0098] A vertically extending slide 43 is provided on the water supply pipe 4, and the water outlet 41 is located in the slide 43 or at the end of the slide 43. The water inlet end of the water pipe 22 can slide along the slide 43 to guide the water pipe 22 to improve the accuracy of the connection between the water pipe 22 and the water outlet 41.

[0099] The slide 43 is in the shape of a trumpet that decreases in diameter as the water pipe 22 moves to the water outlet 41. In this embodiment, the slide 43 becomes smaller in size from bottom to top in the left and right direction, which facilitates the water pipe 22 to smoothly enter the slide 43. When the water pipe 22 corresponds to the water outlet 41, the water pipe 22 is positioned relative to the slide 43 in the left and right direction.

[0100] In this embodiment, Figures 11 to 13 As shown, two vertically extending guide bars 44 are symmetrically arranged on the left and right sides of the water outlet 41, and the area between the two guide bars 44 is the slideway 43. Each guide bar 44 is inclined toward the water outlet 41 along the direction from the water pipe 22 to the water outlet 41, so as to form a bell-shaped slideway 43. Each guide bar 44 includes a downstream section 441 and an upstream section 442 which are sequentially arranged and connected along the direction from the water pipe 22 to the water outlet 41, and the inclination angle of the downstream section 441 is greater than the inclination angle of the upstream section 442, so as to further increase the size of the lower part of the slideway 43 in the left-right direction, so as to facilitate the water pipe 22 to enter the slideway 43.

[0101] Two guide blocks 224 are symmetrically provided on the outer peripheral wall of the water inlet end of the water pipe 22, and a guide groove 443 is provided on the side wall of the slide 43 (i.e., the guide strip 44) along its length direction, and the guide block 224 slides along the guide groove 443 of a guide strip 44; along the direction of the water pipe 22 moving to the water outlet 41, the width of the guide groove 443 gradually decreases, so that the guide block 224 can enter the guide groove 443 easily, and when the water pipe 22 corresponds to the water outlet 41, the guide block 224 is positioned relative to the guide groove 443 in the front-to-back direction.

[0102] The guide block 224 of this embodiment is V-shaped, including a first portion 2241 and a second portion 2242 . The angle between the first portion 2241 and the second portion 2242 is an obtuse angle, which has a good positioning effect with the guide groove 443 .

[0103] like Fig.17 , 18 As shown, a second spray member 32 is provided in the box body 1 . The second spray member 32 can adopt an existing spray arm structure and can rotate around its axis in the box body 1 . The nozzle of the second spray member 32 faces the bowl rack 3 .

[0104] The second spray component 32 is located below the bowl rack 3, and a shelf 45 is provided at the lower part of the water supply pipe 4. The shelf 45 is located above the second spray component 32. When the rack 2 is in the second position, the bottom of the water pipe 22 is placed on the shelf 45 to prevent the water pipe 22 from being in a vertical state when the rack 2 is in the second position, thereby preventing interference with the rotation of the second spray component 32.

[0105] 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 spraying member 32, so as to prevent the shelf 2 from interfering with the rotation of the second spraying member 32 when in the second position. The bowl rack 3 is a hollow structure composed of a plurality of ribs, and the second limiting portion 34 is one of the ribs of the bowl rack 3.

[0106] Regarding the water outlet 41, Fig.11 , 12 As shown, the direction of the water outlet 41 can be inclined or horizontal. In this embodiment, the direction of the water outlet 41 is inclined, and the angle with the horizontal plane is about 25°.

[0107] When the shelf 2 is in the second position, the water outlet 41 can be in a closed state or an open state. 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 .

[0108] In other words, the water outlet 41 has two working states: in the first working state, the water inlet end of the water pipe 22 is connected to the water outlet 41 of the water supply pipe 4, that is, the water outlet 41 is connected to the spray assembly and supplies water to it, and the water sprayed by the spray assembly cleans the items in the cleaning machine; in the second working state, the water inlet end of the water pipe 22 is disconnected 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 acts as a nozzle to spray the items in the cleaning machine, that is, the water outlet 41 can still supply water to flow out, and at this time, it acts as a nozzle to spray the items in the cleaning machine. Because the direction of the water outlet 41 is fixed after production, items in specific parts can be locally enhanced washed.

[0109] The water inlet end of the water pipe 22 of this embodiment is connected to the water outlet 41 of the water supply pipe 4 in the horizontal direction, and the water inlet end of the water pipe 22 can also be connected to the water outlet 41 of the water supply pipe 4 in the vertical direction.

[0110] Because the spray hole of the spray assembly of this embodiment is toward the rack 2, when the water outlet 41 is in the first working state, the rack 2 is located on the water spray 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 part 32 sprays from bottom to top, and the cooperation of the two has a good cleaning effect on the tableware in the bowl rack 3.

[0111] When the shelf 2 is in the first position, it is in a cleaning state, and the spray assembly is connected to the water outlet 41 so that the water outlet 41 is in a first working state; when the shelf 2 is in the second position, it is in a non-cleaning state, and the spray assembly is disconnected from the water outlet 41 so that the water outlet 41 is in a second working state.

[0112] The water outlet 41 is provided with a dividing rib 411, so as to divide the water outlet 41 into a plurality of water outlet holes 412. Different water outlet holes 412 clean different areas of the dish rack 3, and at least two of the water outlet holes 412 face different directions.

[0113] In this description, the spray assembly is not the only component that can spray water on the shelf 2, and the water outlet 41 is not the only component that can spray water on the bowl rack 3. A variety of spray structures can be used for cleaning.

[0114] It can be seen from the above that no matter the shelf 2 is in the first position or the second position, the shelf 2 and the spray assembly are both located in the inner cavity 10 of the box body 1 .

[0115] Example 2

[0116] The difference between this embodiment and the first embodiment is that the structure of the guide rail 24 is different. For other details, please refer to the first embodiment.

[0117] like Figures 20-23 As shown, the height of the connecting member 31 is consistent with the height of the water outlet 41, 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-to-back direction, the inclined section 242 is inclined upward from front to back, and the connecting member 31 extends into the inclined section 242. With this structural form of the guide rail 24, when the shelf 2 is turned over, there will be no interference between the water pipe 22 and the water supply pipe 4.

[0118] Example 3

[0119] The difference between this embodiment and embodiment 1 is that: 1. This embodiment adopts the form of the shelf 2 flipping forward:

[0120] When the shelf 2 is in the first position, the connector 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 spray assembly are both located between the bowl rack 3 and the front wall of the inner cavity 10, that is, the shelf 2 and the spray assembly are both located in the front of the inner cavity 10, in front of the bowl rack 3. In this case, the shelf 2 flips forward, because 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 of the box body 1 too crowded; in addition, the shelf 2 flips to the front side, which will not affect the user's vision and tableware placement experience. In this solution, the guide rail 24 extends straight, and the connector 31 is located obliquely below the water outlet 41 of the water supply pipe 4. When the shelf 2 flips forward, there will be no problem of interference between the water pipe 22 and the water supply pipe 4.

[0121] 2. The shelf 2 of this embodiment is not supported on the support portion 33, but is supported on the bowl rack 3 by the guide rail 24 being supported on the top of the bowl rack 3 when the shelf 2 is in the first position. The guide rail 24 extends in the front-to-back direction and has a large contact area with the bowl rack 3, so that the shelf 2 has good stability.

[0122] The "horizontal" mentioned above includes that the component extends straight in the horizontal direction, that is, the two ends of the component are on the same horizontal plane, but is not limited to this direction, as long as the overall extension direction of the component is in the horizontal direction, such as the component extends along the front and back or left and right directions as a whole, but the two ends of the component are not on the same horizontal plane.

[0123] Similarly, "vertical" includes components extending straight in the vertical direction, that is, the two ends of the component are on the same plumb plane, but 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 in the up and down direction as a whole, but the two ends of the component are not on the same plumb plane.

[0124] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "horizontal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention 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 embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0125] The "fluid communication" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
