Description

Technical Field

[0001] The invention relates to the technical field of water sinks, and in particular to a shelf assembly for a water sink and a water sink. Background Art

[0002] With the widespread use of sinks in modern kitchens, various types of drain racks and fruit and vegetable baskets that match the sinks have been designed. Some drain racks only have the functions of draining and holding fruits and vegetables. Since there is often water on the surface of the drain rack, it will cause moisture and mildew in the cabinet when stored, and needs to be specially dried in the sun. The current drain racks are usually large in size and cannot be folded. No matter where they are placed, they occupy a large area, which is very inconvenient.

[0003] In response to the above problems, the Chinese invention patent application with patent number CN202110271761.0 (publication number CN115067780A) discloses "A folding vegetable basket and cleaning machine for a sink". In the folding vegetable basket for a sink, the auxiliary basket body is connected to the first opening or the first bottom plate of the main basket body. When the main body of the basket is in the first use state, the auxiliary basket body is connected to the first opening of the main basket body, so that the main basket body and the auxiliary basket body are connected at the opening, and the first placement interval and the second placement interval are connected to form a storage tank with an opening facing upward. When the main body of the basket is in the second use state, the auxiliary basket body is at least partially located below the first bottom plate of the main basket body to form support for the main basket body. In this way, the design of a folding vegetable basket with a coordinated switching state of the main basket body and the auxiliary basket body effectively utilizes the folded vegetable basket under the premise of meeting the use of a conventional fruit and vegetable basket. It can not only avoid the space occupied by the separate storage of items and fruit and vegetable baskets, but also ensure the stable support of the storage state by relying on the support of the auxiliary basket body, which is very convenient and practical.

[0004] Although the foldable vegetable basket can be folded to reduce the occupied space, when it is not folded, the relative positioning of the main basket body and the auxiliary basket body is achieved only by the rotation of the rotating shaft and the connecting part. The relative stability of the two basket bodies is poor. Especially when the foldable vegetable basket contains heavy items, relative rotation is likely to occur between the two basket bodies, and the items cannot be placed well. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a shelf assembly for a sink with two baskets having good relative stability in an unfolded state in view of the current state of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a sink using the above-mentioned shelf assembly in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a shelf assembly for a sink, comprising two basket bodies, each of which has a drain hole, each of which comprises a bottom plate and a side plate extending upward from a partial circumference of the bottom plate, so that each of the basket bodies has a first opening facing upward and a second opening facing the side, and the side edge of the bottom plate of the basket body located at the second opening is called a first side edge, and the first side edges of the two basket bodies are rotatably connected by a rotating structure, and the rotating axis of the rotating structure extends along the length direction of the first side edge, so that the shelf assembly has a first use state and a second use state;

[0008] When the shelf assembly is in the first use state, the second openings of the two basket bodies are butted against each other, and the placement intervals of the two basket bodies are joined to form a storage slot with the opening facing upward;

[0009] When the shelf assembly is in the second use state, one of the baskets is located below the other basket;

[0010] Characterized in that the shelf assembly also includes a positioning mechanism, the positioning mechanism includes

[0011] A first positioning block is provided on one of the basket bodies;

[0012] A second positioning block is provided on the other basket body, and when the shelf is in the first use state, the second positioning block can be detachably restrained with the first positioning block, and when the shelf is in the second use state, the first positioning block and the second positioning block are separated;

[0013] The unlocking structure is arranged on one of the basket bodies and is used for releasing the constraints between the first positioning block and the second positioning block.

[0014] In the above scheme, the wall surface of the side plate of the basket body located at the second opening is called the docking surface, the two basket bodies are respectively called the first basket body and the second basket body, the first positioning block is arranged on the first basket body, and the second positioning block is arranged on the second basket body;

[0015] A limiting groove is provided on the side plate of the first basket body at a position adjacent to the second opening, wherein the limiting groove has a first notch and a second notch, and the first notch passes through the butt joint surface of the side plate;

[0016] The second positioning block can extend from the first notch into or out of the limiting groove, and the first positioning block is arranged in the limiting groove and can move toward or away from the second positioning block;

[0017] The unlocking structure can have various structural forms, including:

[0018] An unlocking rod, wherein the unlocking rod can move toward or away from the limiting groove, and the first end of the unlocking rod can extend into the limiting groove from the second notch and be detachably connected to the first positioning block, and in this state, the second positioning block is squeezed by the first positioning block to abut against the wall surface of the limiting groove;

[0019] A first elastic member acts on the first positioning block to keep the first positioning block moving away from the second positioning block;

[0020] A driving rod, capable of abutting against the second end of the unlocking rod and pushing the unlocking rod to move toward the limiting groove;

[0021] The second elastic member acts on the unlocking rod, so that the unlocking rod maintains a tendency to move in a direction away from the limiting groove.

[0022] In order to make the unlocking rod detachably connected to the first positioning block, the first positioning block is provided with a slot, the first end of the unlocking rod is detachably inserted in the slot, and the extending direction of the unlocking rod is perpendicular to the moving direction of the first positioning block.

[0023] Preferably, the portion of the side plate of the first basket body facing the second opening is called the first side wall, the driving rod is located on the outside of the first side wall and is rotatably connected to the first basket body through a connecting rod, the driving rod can be in a first position and a second position, when the driving rod is in the first position, the connecting rod extends vertically, the driving rod is located at the bottom of the connecting rod and abuts against the unlocking rod, and the driving rod is attached to the first side wall of the first basket body; when the driving rod is in the second position, the connecting rod extends laterally in a direction away from the first basket body, and the driving rod and the connecting rod together constitute a hanger for hanging items. The driving rod can not only drive the unlocking rod to move, but also be used to hang items such as rags, so that one item has multiple uses.

[0024] In order to ensure that the unlocking rod, the first positioning block and the second positioning block can cooperate well, the limiting groove includes a connected vertical section and a horizontal section. The vertical section extends vertically and the horizontal section extends horizontally. One end of the horizontal section is connected to the vertical section and the other end is open and is called the first slot. The vertical section is provided with a second slot. The first positioning block can be moved up and down in the vertical section of the limiting groove, and the second positioning block can extend into or out of the horizontal section.

[0025] In order to facilitate the second positioning block to enter or escape from the transverse section of the limiting groove, preferably, the transverse section of the limiting groove is tapered with a gradually decreasing diameter along the direction in which the second positioning block is inserted into the transverse section. The tapered structure not only guides the second positioning block to enter the limiting groove, but also facilitates the second positioning block to enter or escape.

[0026] In the above scheme, when the shelf assembly is in the first use state, the driving rod is in the first position, at which time the driving rod is close to the first side wall of the first basket body and will not affect the placement of the shelf assembly in the tank body of the sink; when the shelf assembly is in the second use state, the driving rod is in the second position, at which time the driving rod is away from the first side wall of the first basket body and items can be hung.

[0027] In order to position the driving rod when the driving rod is in the first position and the second position, one end of the connecting rod is called a connecting part, the first basket body is provided with a mounting shaft, the connecting part is rotatably mounted on the mounting shaft, and the side plate of the first basket body is also provided with a limiting piece, and the connecting part and the limiting piece are detachably restrained together through a clamping block and a clamping groove. When the driving rod is in the first position or the second position, the connecting part and the limiting piece are connected together, and when the driving rod needs to switch positions, the connecting part and the limiting piece are disengaged, so that the connecting rod can rotate.

[0028] Because the second positioning block is extended out of the second basket body in order to be able to extend into the limiting groove, when the shelf assembly switches to the second use state, the second positioning block will interfere with the side wall of the groove body and affect the folding of the second basket body. Therefore, the second positioning block is rotatably connected to the second basket body. When the shelf assembly is in the second use state, the second positioning block extends vertically to avoid interference between the second positioning block and the first basket body.

[0029] In order to enable the second positioning block to rotate, a vertically extending linkage rod is provided on the second basket body, and the linkage rod can move up and down relative to the second basket body in the vertical direction. At least part of the linkage rod is provided with at least two first teeth along its length direction, and the part of the second positioning block connected to the second basket body is provided with a first gear meshing with the first teeth. The linkage rod moves up and down, driving the first gear to rotate, and the second positioning block rotates synchronously.

[0030] In order to improve the stability of the shelf assembly placed in the trough body, the second basket body is provided with a plate body located outside the side plate. When the shelf assembly is in the first use state, the plate body extends horizontally. When the shelf assembly is in the second use state, the plate body extends vertically. The plate body serves as a shelf for being placed on the placing portion of the trough body of the sink.

[0031] In order to prevent the plate from interfering with the first basket when the shelf assembly is in the second use state, thereby affecting the folding of the second basket, a vertical rod extending vertically is further provided on the second basket. The vertical rod can move up and down relative to the second basket in the vertical direction. At least part of the vertical rod is provided with at least two second teeth along its length, and the plate is provided with a second gear meshing with the second teeth. The vertical rod moves up and down, driving the second gear to rotate, and the plate rotates accordingly.

[0032] A driving mechanism may be provided for the vertical rod and the linkage rod respectively, but this involves more parts, so the vertical rod and the linkage rod are fixedly connected by a connecting rod, so that only the vertical rod or the linkage rod is driven.

[0033] A motor can be set to drive the vertical rod or the linkage rod to move, but this involves more parts, so one end of the vertical rod extends out of the bottom plate of the second basket body, and when the shelf assembly is in the second use state, the vertical rod conflicts with the bottom plate of the first basket body and moves downward, and the vertical rod maintains a tendency to move upward under the action of the third elastic member. In this way, when the shelf assembly switches to the second use state, the vertical rod conflicts with the bottom plate of the first basket body and moves downward. When the shelf assembly switches from the second use state to the first use state, the vertical rod is out of conflict with the bottom plate of the first basket body, and the vertical rod moves in the opposite direction under the action of the third elastic member; in this way, no driving parts are required, and the vertical rod can be driven to move up and down, and the linkage rod moves up and down synchronously.

[0034] The technical solution adopted by the present invention to solve the above second technical problem is: a water tank, characterized in that it includes a tank body and the above shelf assembly, the top of the tank body is open, and the shelf assembly is placed in the tank body.

[0035] Preferably, a spraying member located below the shelf assembly is provided in the trough body, and a spraying hole facing the shelf assembly is provided on the spraying member to clean the items in the shelf assembly.

[0036] Compared with the prior art, the advantages of the present invention are as follows: by setting a positioning mechanism, when the shelf assembly is in the first use state, the two basket bodies are relatively fixed together through the positioning mechanism, and the stability is good, which solves the problem that the relative stability between the two basket bodies is poor and affects the placement of items; when the shelf assembly needs to be switched to the second use state, the positioning mechanism can release the relative fixation of the two basket bodies without affecting the folding of the two basket bodies; when the number of items to be placed is large, the shelf assembly is in the first use state, and when the number of items to be placed is small, the shelf assembly is in the second use state, and takes up little space.

[0047] The present invention is further described in detail below with reference to the accompanying drawings.

[0048] like Figures 1 to 10 As shown, the water tank of this preferred embodiment includes a tank body 1 and a shelf assembly. The top of the tank body 1 is open, and the shelf assembly is placed in the tank body 1. The shelf assembly A includes a positioning mechanism and two basket bodies.

[0049] like Figure 4 As shown, each basket body has a drain hole 21, and each basket body includes a bottom plate 22 and a side plate 23 extending upward from a partial circumference of the bottom plate 22, so that each basket body has a first opening 24 facing upward and a second opening 25 facing the side. The bottom plate 22 and the side plate 23 form a placement area 26 for placing items, and items such as tableware, pots and pans, fruits and vegetables can be placed in the basket body.

[0050] The side of the bottom plate 22 of the basket body located at the second opening 25 is called the first side. In this embodiment, the bottom plate 22 is square and includes four sides, namely the first side, the second side, the third side and the fourth side, wherein the first side and the fourth side are arranged opposite to each other, the second side and the third side are arranged opposite to each other, the first side, the second side, the fourth side and the third side are connected end to end in sequence, and the portion of the side plate 23 corresponding to the fourth side is called the first side wall, that is, the portion of the side plate 23 of the basket body facing the second opening 25 is called the first side wall, and the portion of the side plate 23 corresponding to the second side and the third side is called the second side wall.

[0051] The first sides of the two basket bodies are rotatably connected through the rotating structure, so that the shelf assembly has a first use state and a second use state. When the shelf assembly is in the first use state, Figure 4 As shown, the second openings 25 of the two basket bodies are butted, and the placement spaces 26 of the two basket bodies are joined to form a storage slot with the opening facing upward; when the shelf assembly is in the second use state, as shown in FIG. Fig. 9 As shown, one of the basket bodies is located below the other basket body, which is equivalent to the two basket bodies being folded up.

[0052] The water tank can be an ordinary water tank, or a spraying member 27 can be arranged in the water tank, the spraying member 27 is located below the shelf assembly, and a spraying hole facing the shelf assembly is arranged on the spraying member 27 to clean the items in the shelf assembly, in which case the water tank is used as a functional tank of a dishwasher. The spraying member 27 can adopt the structure of an existing spray arm.

[0053] In this embodiment, there are two water tanks. Figure 1 The sink on the left side of the center is a normal sink. Figure 1 The sink on the right side is a functional sink for a dishwasher. The shelf assembly in the first use state can be placed in an ordinary sink or a functional sink for a dishwasher, such as Figure 2 , 3 As shown; Figure 1 The rear part of the tank body 1 of the left side of the water tank is provided with a recessed area facing backward to form a drain area 11, and the shelf assembly in the second use state can be placed in the drain area 11, such as Figure 1 shown.

[0054] In order to stably place the shelf assembly in the tank body 1, at least one of the side panels 23 of the basket body is provided with a shelf, and the tank body 1 is provided with a shelf portion 12 for the shelf to be placed thereon. The shelf portion 12 can be arranged on the inner wall surface of the peripheral wall of the tank body 1, and the shelf portion 12 can also be the top wall surface of the tank body 1; in this embodiment, Figure 1 The shelf portion 12 of the tank body 1 on the left side is the top wall of the tank body 1. The shelf assembly in the tank body 1 is mainly used to place items that need to be drained. Figure 1 The shelf portion 12 of the tank body 1 on the middle right side is arranged on the inner wall surface of the peripheral wall of the tank body 1, and the shelf assembly is mainly used for placing items to be cleaned.

[0055] like Figure 8 As shown, the rotating structure includes a pin 28 provided on one of the basket bodies and an axial hole 29 provided on the other basket body, the pin 28 extends along the length direction of the first side, and the pin 28 is rotatably provided in the axial hole 29 around its axis. Only relying on the cooperation between the pin 28 and the axial hole 29, when the shelf assembly is in the first use state, displacement is easily generated between the two basket bodies, so a positioning mechanism is also provided, and the positioning mechanism includes a first positioning block 31, a second positioning block 32 and an unlocking structure.

[0056] The first positioning block 31 is arranged on one of the basket bodies, and the second positioning block 32 is arranged on the other basket body. When the shelf is in the first use state, the second positioning block 32 can be detachably constrained together with the first positioning block 31. When the shelf is in the second use state, the first positioning block 31 and the second positioning block 32 are disengaged, and an unlocking structure is arranged on one of the basket bodies for releasing the constraints of the first positioning block 31 and the second positioning block 32.

[0057] The wall surface of the side plate 23 of the basket body located at the second opening 25 is called a docking surface, that is, the side wall surface of the second side wall located at the second opening 25 is a docking surface.

[0058] The two baskets are respectively called the first basket 2a and the second basket 2b. When the shelf assembly is in the second use state, the second basket 2b is located below the first basket 2a. The first positioning block 31 is provided on the first basket 2a, and the second positioning block 32 is provided on the second basket 2b.

[0059] like Figure 5 , 6 As shown in FIGS. 7 and 8, a limiting groove 33 is provided on the side plate 23 of the first basket body 2a at a position adjacent to the second opening 25. The limiting groove 33 has a first notch 331 and a second notch 332. The first notch 331 passes through the docking surface of the side plate 23. In this embodiment, the limiting groove 33 includes a vertical section 333 and a transverse section 334 connected to each other. The vertical section 333 extends vertically, and the transverse section 334 extends transversely. One end of the transverse section 334 is connected to the upper end of the vertical section 333, and the other end is open and is called the first notch 331. The vertical section 333 is provided with a second notch 332. The second positioning block 32 can extend into or out of the transverse section 334 from the first notch 331. In order to facilitate the second positioning block 32 to enter or out of the transverse section 334 of the limiting groove 33, preferably, the transverse section 334 of the limiting groove 33 is tapered with a gradually decreasing diameter along the direction in which the second positioning block 32 is inserted into the transverse section 334.

[0060] The first positioning block 31 is movably disposed in the vertical section 333 of the limiting groove 33 so as to move toward or away from the second positioning block 32. The first positioning block 31 can squeeze the second positioning block 32 so that the second positioning block 32 abuts against the top wall surface of the transverse section 334, thereby positioning the second positioning block 32 in the limiting groove 33.

[0061] The unlocking structure includes a first elastic member 341 , an unlocking rod 34 , a driving rod 35 and a second elastic member 351 .

[0062] The unlocking rod 34 can move toward or away from the limiting groove 33, and the first end of the unlocking rod 34 can extend into the limiting groove 33 from the second slot 332. The extending direction of the unlocking rod 34 is perpendicular to the moving direction of the first positioning block 31. The first positioning block 31 is provided with a slot 311, and the first end of the unlocking rod 34 can be detachably inserted into the slot 311 to realize that the unlocking rod 34 and the first positioning block 31 are detachably connected, and when the unlocking rod 34 is connected to the first positioning rod 31, the first positioning block 31 squeezes the second positioning block 32 so that the second positioning block 32 is against the wall of the limiting groove 33.

[0063] The first elastic member 341 acts on the first positioning block 31, so that the first positioning block 31 keeps moving away from the second positioning block 32. The first elastic member 341 is a spring, one end of which abuts against the bottom wall of the limiting groove 33, and the other end abuts against the first positioning block 31.

[0064] The second elastic member 351 acts on the unlocking rod 34, so that the unlocking rod 34 maintains a tendency to move in a direction away from the limiting groove 33. A first guide groove 201 extending in a horizontal direction is provided on the second side wall of the first basket body 2a. The unlocking rod 34 is provided in the first guide groove 201 and can move along the length direction of the first guide groove 201 to guide the moving track of the unlocking rod 34. The second elastic member 351 is a spring, one end of which is against the unlocking rod 34, and the other end is against the wall surface of the first guide groove 201.

[0065] The driving rod 35 can abut against the second end of the unlocking rod 34 and push the unlocking rod 34 to move toward the limiting groove 33. The driving rod 35 is located on the outer side of the first side wall of the first basket body 2a, and the driving rod 35 is rotatably connected to the first basket body 2a through the connecting rod 352. The driving rod 35 can be in a first position and a second position. When the driving rod 35 is in the first position, the connecting rod 352 extends vertically, the driving rod 35 is located at the bottom of the connecting rod 352 and abuts against the unlocking rod 34, and the driving rod 35 is close to the first side wall of the first basket body 2a; when the driving rod 35 is in the second position, the connecting rod 352 extends laterally in a direction away from the first basket body 2a, and the driving rod 35 and the connecting rod 352 together constitute a hanger for hanging items. The driving rod 35 can not only drive the unlocking rod 34 to move, but also be used to hang items such as rags, which is a multi-purpose item.

[0066] When the shelf assembly is in the first use state, the driving rod 35 is in the first position, at which time the driving rod 35 is attached to the first side wall of the first basket body 2a, and the driving rod 35 will not interfere with the trough body 1, and will not affect the placement of the shelf assembly in the trough body 1 of the sink. When the shelf assembly is in the second use state, the driving rod 35 is in the second position, at which time the driving rod 35 is away from the first side wall of the first basket body 2a, and items can be hung.

[0067] One end of the connecting rod 352 is called a connecting portion 353. A mounting shaft 202 is provided on the second side wall of the first basket body 2a. The connecting portion 353 is rotatably mounted on the mounting shaft 202. A stopper 4 is also provided on the second side wall of the first basket body 2a. The connecting portion 353 and the stopper 4 are detachably restrained together by a clamping block 354 and a clamping slot 41. When the driving rod 35 is located at the first position or the second position, the connecting portion 353 and the stopper 4 are connected together. When the driving rod 35 needs to switch positions, the connecting portion 353 and the stopper 4 are separated, so that the connecting rod 352 can rotate. In this embodiment, the clamping slot 41 is provided on the connecting portion 353, and the clamping block 354 is provided on the stopper 4. The clamping block 354 is in a tapered shape with a gradually reduced diameter in a direction away from the connecting portion 353. The clamping slot 41 is in a tapered shape adapted to the clamping block 354. Under the action of an external force, the clamping block 354 can be separated from the clamping slot 41.

[0068] In order to be able to extend into the limiting groove 33, the second positioning block 32 is extended laterally from the second basket body 2b. In this way, when the shelf assembly switches to the second use state, the second positioning block 32 will interfere with the first basket body 2a, affecting the folding of the second basket body 2b. Therefore, the second positioning block 32 is rotatably connected to the second basket body 2b. When the shelf assembly is in the second use state, the second positioning block 32 extends vertically to avoid interference between the second positioning block 32 and the side wall of the groove body 1.

[0069] like Figure 7 , 10 As shown, a vertically extending linkage rod 51 is provided on the second basket body 2b, and the linkage rod 51 can move up and down relative to the second basket body 2b in the vertical direction. At least part of the linkage rod 51 is provided with at least two first teeth 511 along its length direction, and a portion of the second positioning block 32 connected to the second basket body 2b is provided with a first gear 321 meshing with the first teeth 511. The linkage rod 51 moves up and down, driving the first gear 321 to rotate, and the second positioning block 32 rotates synchronously.

[0070] The first basket body 2a is provided with a shelf 203, which can be placed on the shelf portion 12 of the trough body 1 to position the shelf assembly. However, when the shelf assembly is in the first use state, it can contain more items and the overall weight is heavy. The positioning effect is not good relying solely on the shelf 203 on the first basket body 2a. Therefore, in order to improve the stability of the shelf assembly placed in the trough body 1, the second basket body 2b is provided with a plate body 204 located on the outside of the side plate 23. When the shelf assembly is in the first use state, the plate body 204 extends horizontally. At this time, the plate body 204 serves as a shelf for being placed on the shelf portion 12 of the trough body 1 of the sink. When the shelf assembly is in the second use state, the plate body 204 extends vertically and will not interfere with the side wall of the trough body 1.

[0071] The second basket body 2b is also provided with a vertical rod 52 extending vertically, and the vertical rod 52 can move up and down relative to the second basket body 2b in the vertical direction, and at least a portion of the vertical rod 52 is provided with at least two second teeth 521 along its length direction, and the plate body 204 is provided with a second gear 205 meshing with the second teeth 521. The vertical rod 52 moves up and down, driving the second gear 205 to rotate, and the plate body 204 rotates accordingly.

[0072] The vertical rod 52 and the linkage rod 51 are fixedly connected by the connecting rod 53, so that only the vertical rod 52 or the linkage rod 51 is driven to realize the synchronous movement of the two. One end of the vertical rod 52 extends out of the bottom plate 22 of the second basket body 2b. When the shelf assembly is in the second use state, the vertical rod 52 conflicts with the bottom plate 22 of the first basket body 2a and moves downward, and the vertical rod 52 maintains the upward movement trend under the action of the third elastic member 522. In this way, when the shelf assembly switches to the second use state, the vertical rod 52 conflicts with the bottom plate 22 of the first basket body 2a and moves downward. When the shelf assembly switches from the second use state to the first use state, the vertical rod 52 is out of conflict with the bottom plate 22 of the first basket body 2a, and the vertical rod 52 moves in the opposite direction under the action of the third elastic member 522; in this way, no driving component is required, and the vertical rod 52 can be driven to move up and down, and the linkage rod 51 moves up and down synchronously.

[0073] In this embodiment, a second guide groove 206 and a third guide groove 207, both of which extend vertically, are provided on the second side wall of the second basket body 2b. The linkage rod 51 is provided in the second guide groove 206 and can move along the second guide groove 206.
