Description

Technical Field

[0001] This invention relates to the field of hardware products technology, and in particular to a multifunctional sink. Background Technology

[0002] In current technology, the function of kitchen sinks is relatively simple, mainly for washing and draining. Conventional draining usually relies on a separate drain basket placed on the countertop or sink, which not only takes up valuable countertop space but can also lead to secondary contamination or bacterial growth due to water accumulation. Some designs attempt to combine the drain basket with the sink, but these baskets are mostly static, relying on gravity for drainage, which is inefficient and cannot effectively remove excess moisture from the surface of food (such as vegetables and fruits). Furthermore, for scenarios requiring slight shaking or even draining, users often need to manually shake or rotate the drain basket, which is inconvenient and laborious. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a multifunctional sink with higher integration, richer functions and convenient operation.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A multifunctional sink includes a sink body with a rectangular opening at the upper end. A rectangular pool and a circular pool are spaced apart on the left and right sides within the rectangular opening. A rotatable drain basket is suspended within the circular pool. A support plate slides left and right within the rectangular opening. A one-way rotation mechanism is provided on the support plate. The support plate can slide above either the rectangular pool or the circular pool. When the support plate slides above the circular pool, the one-way rotation mechanism connects to the drain basket and drives the drain basket to rotate unidirectionally.

[0006] In some embodiments, the upper edge of the drain basket is provided with a circular hanging lug, the upper end of the circular trough is provided with a circular guide groove, the circular hanging lug is rotatably disposed in the circular guide groove, and a vertically extending vertical rod is provided at the inner center of the drain basket, the vertical rod being connected to the unidirectional rotational power mechanism.

[0007] In some embodiments, the unidirectional rotational power mechanism includes a first pinion and a unidirectional gear that are rotatably meshed within a support plate. A connecting seat is provided at the lower end of the first pinion, and a connecting notch is provided on one side of the connecting seat. A horizontal guide groove communicating with the connecting notch is provided on the lower side of the support plate. A rectangular connecting block is provided at the upper end of the vertical rod. The rectangular connecting block can slide into the connecting notch through the horizontal guide groove. A rack that can mesh with the unidirectional gear is also slidably mounted in the support plate. One end of the rack extends out of the support plate and is provided with a drive handle.

[0008] In some embodiments, the one-way gear includes a large gear that meshes with the first small gear, a circular groove is provided at the lower end of the large gear, a ratchet is coaxially rotatably mounted in the circular groove, a pawl that meshes with the ratchet and a first spring for keeping the pawl and the ratchet engaged are also provided on the circular groove, and a second small gear is coaxially fixedly provided at the lower end of the ratchet, the second small gear meshing with the rack.

[0009] In some embodiments, a fixing sleeve is provided on the tank body and located between the rectangular tank body and the circular tank body. An installation protrusion ring is provided on the outer wall of the fixing sleeve. The installation protrusion ring is installed on the upper end face of the tank body. A rotating tube is rotatably installed inside the fixing sleeve. A faucet assembly is provided on the rotating tube.

[0010] In some embodiments, a transmission assembly is also connected between the support plate and the rotating tube. When the support plate slides to the rectangular pool, the transmission assembly can drive the rotating tube to rotate, thereby turning the faucet assembly to the circular trough pool. Or when the support plate slides to the circular trough pool, the transmission assembly can drive the rotating tube to rotate, thereby turning the faucet assembly to the rectangular pool.

[0011] In some embodiments, the transmission assembly includes a gear ring disposed on the side wall of the rotating tube, a transmission gear that meshes with the gear ring is rotatably disposed on the mounting convex ring, and a plurality of teeth that can mesh with the transmission gear are disposed on one side of the support plate.

[0012] In some embodiments, a limiting ring is provided at the upper end of the mounting protrusion, a limiting notch is provided on the limiting ring, and a metal limiting block is provided on the rotating tube. The metal limiting block is movably disposed within the limiting notch, and magnets capable of magnetically attracting the metal limiting block are embedded on both ends of the limiting notch.

[0013] In some embodiments, the faucet assembly includes an L-shaped tube rotatably fitted onto the upper end of the rotating tube, a faucet is provided at the other end of the L-shaped tube, the faucet is connected to a soft water pipe, and the soft water pipe passes through the L-shaped tube and the rotating tube.

[0014] In some embodiments, a convex ring is provided at the upper end of the rotating tube, and one end of the L-shaped tube is rotatably sleeved on the convex ring. A plurality of positioning grooves are evenly distributed along the circumference of the outer wall of the convex ring. A circular slot is provided on the L-shaped tube, and a second spring and a positioning steel ball are provided in the circular slot. The positioning steel ball abuts against the positioning groove under the action of the second spring.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. A rectangular cleaning tank and a circular tank with a rotating drain basket are integrated into a single tank, and a sliding support plate is innovatively set up to realize multiple functions such as cleaning, static draining, and active rotating draining (spin-drying) in one unit.

[0017] 2. By setting up a unidirectional rotating drain basket and a matching power mechanism, users can place the food in the drain basket and drive it to rotate, using centrifugal force to actively remove the water from the surface of the food. Compared with traditional gravity static draining, this method can remove excess water more quickly and thoroughly, and is especially suitable for washed vegetables, salads, fruits, etc., significantly improving draining efficiency and effect.

[0018] 3. The cleverly designed sliding support plate allows for easy connection between the user and the drain basket when it slides over the circular sink. When slid over the rectangular sink, it can be used as a temporary shelf, cutting board, or work surface, increasing the sink's functionality. This design reduces the steps required for users to find and change different tools, improving the smoothness of operation.

[0019] 4. The rectangular and circular troughs are designed separately to meet different cleaning and draining needs; the drain basket is hung for easy access and cleaning; the unidirectional rotation design ensures safe use and prevents inconvenience or danger caused by reverse rotation.

[0030] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0031] like Figures 1-10 The multifunctional sink shown includes a sink body 1, with a rectangular opening 2 at the upper end of the sink body 1. A rectangular pool body 3 and a circular pool body 4 are spaced apart on the left and right sides within the rectangular opening 2. A rotatable drain basket 5 is hung in the circular pool body 4. A support plate 6 also slides left and right within the rectangular opening 2. A one-way rotation power mechanism is provided on the support plate 6. The support plate 6 can slide above the rectangular pool body 3 or the circular pool body 4. When the support plate 6 slides above the circular pool body 4, the one-way rotation power mechanism is connected to the drain basket 5 and can drive the drain basket 5 to rotate in one direction.

[0032] According to the above structure, the support plate 6 can slide left and right within the rectangular slot 2. When active draining or spin-drying is required, the support plate 6 is slid above the circular trough 4. At this time, the unidirectional rotation power mechanism set on the support plate 6 is connected to the drain basket 5 hanging in the circular trough 4.

[0033] The unidirectional rotational power mechanism is activated, and the output power drives the drain basket 5 to rotate unidirectionally within the circular trough pool 4. Under the action of centrifugal force, the water adhering to the surface of the items placed in the drain basket 5 is thrown out and falls into the circular trough pool 4 below through the holes of the drain basket 5, thereby achieving the purpose of efficient dehydration.

[0034] When the rotating draining function is not needed, the support plate 6 can be slid above the rectangular pool 3; at this time, the unidirectional rotating power mechanism is disengaged from the drain basket 5; the support plate 6 can be used as a cover or temporary shelf for the rectangular pool 3, while the drain basket 5 can be used as a regular static draining container.

[0035] Furthermore, by sliding the support plate 6, the spatial position can be changed and the functional components can be coupled or separated, thus enabling a water tank to integrate multiple functions such as static cleaning, dynamic rotating draining, and temporary placement.

[0036] See Figures 3-5 As shown, the upper edge of the drain basket 5 is provided with a circular hanging ear 21, and the upper end of the circular trough pool 4 is provided with a circular guide groove 22. The circular hanging ear 21 is rotatably disposed in the circular guide groove 22. A vertically extending vertical rod 23 is provided in the center of the interior of the drain basket 5, and the vertical rod 23 is connected to the unidirectional rotation power mechanism.

[0037] The drain basket 5 is suspended and nested in the annular guide groove 22 provided at the upper end of the circular trough 4 by the annular hanging ears 21 provided at its upper edge. The annular hanging ears 21 can rotate freely in the annular guide groove 22. The annular guide groove 22 provides circumferential and uniform support and limit for the entire drain basket 5, so that the drain basket 5 can only rotate around its central axis without tilting or shaking, ensuring the smoothness and safety of the rotating draining process.

[0038] Meanwhile, a vertically extending rod 23 is fixedly installed in the center of the drain basket 5. The core function of the rod 23 is to serve as a power transmission shaft for connecting to a unidirectional rotating power mechanism.

[0039] See Figure 2 , Figures 5-7The unidirectional rotational power mechanism includes a first pinion 31 and a unidirectional gear that are rotatably meshed within the support plate 6. A connecting seat 32 is provided at the lower end of the first pinion 31, and a connecting notch 33 is provided on one side of the connecting seat 32. A horizontal guide groove 34 that communicates with the connecting notch 33 is provided on the lower side of the support plate 6. A rectangular connecting block 35 is provided at the upper end of the vertical rod 23. The rectangular connecting block 35 can slide into the connecting notch 33 through the horizontal guide groove 34. A rack 36 that can mesh with the unidirectional gear is also slidably mounted on the support plate 6. One end of the rack 36 extends out of the support plate 6 and is provided with a drive handle 37.

[0040] Furthermore, the one-way gear includes a large gear 41 that meshes with the first small gear 31. A circular groove 42 is provided at the lower end of the large gear 41. A ratchet 43 is rotatably mounted coaxially in the circular groove 42. A pawl 44 that cooperates with the ratchet 43 and a first spring 45 for keeping the pawl 44 and the ratchet 43 in cooperation are also provided on the circular groove 42. A second small gear 46 is fixedly provided coaxially at the lower end of the ratchet 43. The second small gear 46 meshes with the rack 36.

[0041] When the user slides the support plate 6 directly above the circular trough pool 4, the rectangular connecting block 35 at the upper end of the central vertical rod 23 of the drain basket 5 is horizontally pushed into the horizontal guide groove 34 on the lower side of the support plate 6. Continuing to push the drain basket 5, the rectangular connecting block 35 slides along the horizontal guide groove 34 into the connecting notch 33 located on one side of the connecting seat 32. Since both the rectangular connecting block 35 and the connecting notch 33 have rectangular (or other non-circular) cross-sectional shapes, this fit achieves circumferential locking, thus fixing the vertical rod 23 and the connecting seat 32 together. The connecting seat 32 is fixedly installed at the lower end of the first pinion 31. Thus, the power transmission path connection from the drain basket 5 to the first pinion 31 is completed.

[0042] The user then pulls out or pushes in the drive handle 37 extending beyond the support plate 6. The linear motion of the drive handle 37 causes the rack 36, which is fixedly connected to it, to slide left and right within the support plate 6. The sliding rack 36 will maintain engagement with the second pinion 46, thereby driving the second pinion 46 to rotate. The second pinion 46 is fixedly connected to the ratchet 43 on the same axis, so the ratchet 43 attempts to rotate. The ratchet 43 is installed in the circular groove 42 at the lower end of the large gear 41 of the one-way gear. The circular groove 42 is provided with a pawl 44 that maintains engagement with the ratchet 43 under the action of the spring 45. This structure constitutes a typical ratchet and pawl one-way overrunning clutch.

[0043] When the rack 36 drives the second pinion 46 and the ratchet 43 fixed coaxially with it to rotate, and the pawl 44 rotates in the direction that it can engage with the ratchet tooth groove, the tip of the pawl 44 will be tightly engaged in the tooth groove of the ratchet 43 under the action of the first spring 45. At this time, the pawl 44 acts as a connector, mechanically locking the ratchet 43 with the circular groove 42 (i.e. the main body of the large gear 41) where the pawl 44 is installed. The rotation of the ratchet 43 is forcibly transmitted to the large gear 41, so that the two rotate synchronously and in the same direction. The rotation of the large gear 41 then drives the first pinion 31 that meshes with it, and finally drives the drain basket 5 to rotate.

[0044] When the rack 36 drives the second pinion 46 and ratchet 43 to rotate in the opposite direction, the back of the ratchet 43's teeth will push up or push the pawl 44 away, forcing the pawl 44 to overcome the elastic force of the first spring 45 and lift up, and slide on the back of the ratchet teeth. During this process, the pawl 44 cannot engage with the ratchet teeth, thus losing its function of locking the ratchet 43 and the large gear 41. The ratchet 43 rotates freely in the opposite direction in the circular groove 42 and cannot drive the large gear 41 to rotate.

[0045] The large gear 41 meshes with the first small gear 31. When the large gear 41 is driven to rotate, it transmits motion to the first small gear 31. Finally, the rotational motion is transmitted to the vertical rod 23 through the connected connecting seat 32 and the rectangular connecting block 35, thereby driving the entire drain basket 5 to rotate stably in one direction within the circular trough pool 4.

[0046] See Figure 1 , Figure 2 , Figure 8 As shown, a fixing sleeve 71 is provided on the tank 1 and located between the rectangular tank 3 and the circular tank 4. An installation protrusion ring 72 is provided on the outer wall of the fixing sleeve 71. The installation protrusion ring 72 is installed on the upper end face of the tank 1. A rotating tube 73 is rotatably installed inside the fixing sleeve 71. A faucet assembly is provided on the rotating tube 73.

[0047] A rotatable central faucet assembly is added between the rectangular pool body 3 and the circular pool body 4 of the water tank; the fixed sleeve 71 is securely installed on the upper end face of the tank body 1 through the mounting protrusion 72 on its outer wall. The mounting protrusion 72 plays a supporting and positioning role, ensuring that the fixed sleeve 71 is vertically fixed. The rotating tube 73 is located inside the fixed sleeve 71 and can be rotated at a limited angle relative to the fixed sleeve 71 with the help of bearings or lubrication bushings (not shown in the figure, but it is a conventional technique of "rotational installation").

[0048] See Figure 1 , Figures 8-10As shown, a transmission assembly is also connected between the support plate 6 and the rotating tube 73. When the support plate 6 slides to the rectangular pool 3, it can drive the rotating tube 73 to rotate through the transmission assembly, thereby turning the faucet assembly to the circular trough pool 4. Or when the support plate 6 slides to the circular trough pool 4, it can drive the rotating tube 73 to rotate through the transmission assembly, thereby turning the faucet assembly to the rectangular pool 3.

[0049] Furthermore, the transmission assembly includes a gear ring 61 disposed on the side wall of the rotating tube 73, and a transmission gear 62 that meshes with the gear ring 61 is rotatably disposed on the mounting convex ring 72. A plurality of teeth 63 that can mesh with the transmission gear 62 are disposed on the side of the support plate 6 near the rotating tube 73.

[0050] When the support plate 6 slides from the circular trough 4 to above the rectangular trough 3, during the sliding process, the teeth 63 on the side of the support plate 6 will engage with the transmission gear 62. As the support plate 6 moves to the left, its teeth 63 will push the transmission gear 62 to rotate, causing the transmission gear 62 to rotate clockwise. The clockwise rotation of the transmission gear 62 will drive the gear ring 61, which is always engaged with it, to rotate in the opposite direction, i.e., counterclockwise. Since the gear ring 61 is fixedly installed on the rotating tube 73, the rotating tube 73, together with the faucet assembly on it, will rotate counterclockwise. Through the design of the number of gear teeth, this rotation angle is precisely controlled to about 90 degrees, thereby moving the faucet outlet to the position above the circular trough 4.

[0051] Similarly, when the support plate 6 slides in the opposite direction (to the right), the teeth 63 on its side mesh with the transmission gear 62 again, but this time the direction of movement is opposite, which will push the transmission gear 62 to rotate counterclockwise. The counterclockwise rotation of the transmission gear 62 drives the gear ring 61 and the rotating tube 73 to rotate clockwise (also about 90 degrees), thereby moving the faucet outlet to the state above the rectangular pool body 3.

[0052] This design creates an intuitive and efficient functional linkage logic. For example, when the user needs to operate the drain basket (to rotate and drain water), the support plate 6 will slide above the circular trough 4. At the same time, the linkage mechanism will automatically turn the faucet to the rectangular trough 3. In this way, the rectangular trough 3 will be freed up to conveniently receive the water flowing from the faucet for washing operations, while the draining operation will be carried out on the other side without interfering with each other.

[0053] See Figure 8As shown, a limiting ring 81 is provided at the upper end of the mounting protrusion ring 72, a limiting notch 82 is provided on the limiting ring 81, and a metal limiting block 83 is provided on the rotating tube 73. The metal limiting block 83 is movably disposed in the limiting notch 82, and magnets 84 that can magnetically attract the metal limiting block 83 are embedded on both ends of the limiting notch 82.

[0054] A limiting ring 81 is fixedly installed on the upper end of the mounting protrusion 72, forming a stationary reference platform. An arc-shaped limiting notch 82 is provided on the limiting ring 81. The arc length of this notch (i.e., the angle between the two ends) is precisely designed to correspond to the total angle of rotation required by the rotating tube 73 (e.g., 90 degrees). A metal limiting block 83 is fixedly installed on the side wall of the rotating tube 73. Therefore, when the rotating tube 73 rotates, the metal limiting block 83 will slide along the arc-shaped trajectory of the limiting notch 82.

[0055] When the rotating tube 73 starts to rotate, it drives the metal limiting block 83 on it to slide within the limiting notch 82. When the rotating tube 73 rotates to a predetermined angle so that the faucet assembly is exactly aligned with the rectangular pool body 3, the metal limiting block 83 also slides to one end of the limiting notch 82. At this time, the metal limiting block 83 is mechanically blocked by the side wall at the end of the notch and cannot continue to move forward, thus forcibly stopping the further rotation of the rotating tube 73. This ensures the accuracy of the faucet pointing and prevents angular overshoot caused by inertia or transmission clearance. Similarly, when the rotating tube 73 is driven in the opposite direction to the faucet aligned with the circular trough pool body 4, the metal limiting block 83 will slide to and be blocked at the other end of the limiting notch 82.

[0056] In addition, the magnet 84 will generate a magnetic attraction force on the metal limit block 83, eliminating any small gaps or wobbling that may exist in the transmission system, so that the rotating tube 73 will finally stop very stably.

[0057] See Figures 8-10 As shown, the faucet assembly includes an L-shaped tube 91 that is rotatably sleeved on the upper end of the rotating tube 73. A faucet 92 is provided at the other end of the L-shaped tube 91. The faucet 92 is connected to a soft water pipe 93, which passes through the L-shaped tube 91 and the rotating tube 73.

[0058] Furthermore, a convex ring 10 is provided at the upper end of the rotating tube 73, and one end of the L-shaped tube 91 is rotatably sleeved on the convex ring 10. Several positioning grooves 11 are evenly distributed along the circumference on the outer wall of the convex ring 10. A circular hole groove 12 is provided on the L-shaped tube 91. A second spring 13 and a positioning steel ball 14 are provided in the circular hole groove 12. The positioning steel ball 14 abuts against the positioning groove 11 under the action of the second spring 13.

[0059] Based on the automatic overall steering (switch pool) of the rotating tube 73, an L-shaped tube mechanism that allows for manual stepless adjustment of the water outlet angle has been added. The spring steel ball positioning structure provides a clear angle setting, thus achieving dual flexibility in both automatic switching and manual fine-tuning of the faucet's water outlet direction.

[0060] When the user manually rotates the L-shaped tube 91, the spherical surface of the positioning steel ball 14 will roll along the smooth outer wall of the convex ring 10; when the L-shaped tube 91 is rotated to a certain angle, so that the positioning steel ball 14 is aligned with a certain positioning groove 11 on the convex ring 10, the positioning steel ball 14 will spring into the groove under the thrust of the second spring 13.

[0061] The steel ball falling into the groove creates a mechanical obstruction, requiring the user to apply a certain torque to overcome the spring force and push the steel ball out. This makes the L-shaped tube 91 less likely to rotate accidentally due to water flow impact or slight contact, thus achieving angle self-locking.

[0062] Thus, the L-shaped pipe 91 and its front faucet 92 can rotate 360 ​​degrees freely in the horizontal plane independently of the rotating pipe 73; this is used for fine, user-defined angle adjustment of the water outlet direction.

[0063] In addition, to ensure uninterrupted water supply when the L-shaped pipe 91 rotates freely, a flexible connection scheme is adopted: the faucet 92 supplies water through a soft water pipe 93 (such as a stainless steel braided hose); the soft water pipe 93 is inserted from top to bottom through the interior of the L-shaped pipe 91 and the rotating pipe 73, and finally connected to the water supply system below; no matter how the L-shaped pipe 91 rotates, the soft water pipe 93 can bend and twist freely inside it without affecting the water flow, or causing entanglement or wear.

The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
