Description

Technical Field

[0001] The present application relates to the field of household technology, and in particular to a water tank structure. Background Art

[0002] In the prior art, a sink structure usually includes a sink and a countertop. The sink includes an inner tank and a circle of frame connected to the outside of the top of the inner tank, and the sink can generally be installed to the countertop through three different installation methods: above-the-counter sink installation, mid-the-counter sink installation, and under-the-counter sink installation. Among them, above-the-counter sink installation means that the inner tank is embedded in the through opening of the countertop, and the frame overlaps the upper surface of the countertop and protrudes from the upper surface of the countertop; mid-the-counter sink installation means that the inner tank is embedded in the through opening of the countertop, and the frame overlaps the embedded groove on the upper surface of the countertop and is flush with the upper surface of the countertop; under-the-counter installation means that the frame is connected to the lower surface of the countertop.

[0003] However, when the above-the-counter sink installation method is adopted, since the frame of the sink protrudes from the upper surface of the countertop, the liquid on the upper surface of the countertop cannot be smoothly transferred into the sink tank, which will cause water to remain on the countertop, and it is easy for dirt to remain on the countertop or mold to grow. When the mid-counter sink installation method is adopted, the joint between the countertop and the sink is visible under continuous use and may even open, and the dirt remaining in the joint is not easy to clean. When the under-the-counter sink installation method is adopted, the gap between the sink frame and the countertop is larger, which is easy for residual dirt to remain.

[0004] It can be seen that the sink structure installed by the above installation method fails to simultaneously meet the dual performance requirements of conveniently cleaning the water on the countertop and reducing the gap between the countertop and the sink. Utility Model Content

The first supporting portion is supported on the fixing member, the second supporting portion is connected to the inner side of the first supporting portion, and at least part of the structure of the second supporting portion is supported on the top surface of the annular side plate. The top surface of the second supporting portion is set as an arc surface, and the arc surface is smoothly transitioned to the top surface of the first supporting portion and the inner wall of the annular side plate.

[0009] In one embodiment, the fixing member includes a connecting ring and a supporting ring which are connected to each other. The connecting ring is fixedly mounted on the outer side of the annular side plate. The supporting ring is connected to the bottom or top of the connecting ring and is perpendicular to the annular side plate. The top surface of the supporting ring is used to support the first supporting part.

[0010] In one embodiment, the top surface of the connecting ring is flush with the top surface of the annular side plate, and the top surface of the connecting ring and the top surface of the annular side plate jointly support the second supporting portion.

[0011] In one embodiment, the connecting ring and the annular side plate are welded to each other.

[0012] In one embodiment, the fixing member is an integrated sheet metal structure.

[0013] In one embodiment, the water tank structure further includes a sealant layer, and the sealant layer is at least filled between the bottom surface of the second supporting portion and the top surface of the annular side plate.

[0014] In one embodiment, the water tank structure also includes a connecting assembly, which includes a threaded connector, a nut and a fastener, one end of the threaded connector is fixedly connected to the bottom of the first support portion, the fastener is sleeved on the threaded connector, the nut is threadedly connected to the threaded connector and is located on a side of the fastener away from the first support portion, so that the two ends of the fastener are respectively abutted against the bottom of the fixing member and the bottom of the first support portion.

[0015] In one embodiment, the threaded connector includes a rod and a head that are connected to each other, the head is bonded to the bottom surface of the first support portion, and the rod is used for the fastener to be sleeved and threadedly connected to the nut.

[0016] In one embodiment, the fastener includes a first bending section, a second bending section and a third bending section that are bent and connected in sequence, the second bending section is sleeved on the threaded connector and is elastic, one end of the first bending section away from the second bending section abuts against the bottom of the fixing member, and one end of the third bending section away from the second bending section abuts against the bottom of the first support portion.

[0017] In one embodiment, the fixing member is an annular structure, and the number of the connecting components is multiple, and the multiple connecting components are arranged at intervals along the circumference of the fixing member.

[0018] The beneficial effect of the water tank structure provided by the present application is that: compared with the prior art, the water tank structure provided by the present application, its inner tank includes a bottom plate and an annular side plate connected to the outer edge of the bottom plate, the outer side of the annular side plate is fixedly connected with a fixing piece, and the table top includes a first supporting part and a second supporting part connected to each other, the first supporting part can be supported on the fixing piece, the second supporting part can be supported on the annular side plate, and the top surface of the second supporting part is an arc surface, and the arc surface is smoothly transitioned to the inner side wall of the annular side plate and the top surface of the first supporting part; such a design makes the first supporting part and the top surface and the inner side wall of the annular side plate smoothly transitioned to each other through an arc surface, and the accumulated water on the first supporting part can flow smoothly to the inner side wall of the annular side plate through the arc surface, and it is not easy for water to accumulate on the first supporting part, and the second supporting part itself has a arc surface, and it is also not easy for water to accumulate. ; Moreover, under the action of gravity, the bottom surface of the second support part is directly attached to the top surface of the annular side plate, and the height of the gap between the bottom surface of the second support part and the top surface of the annular side plate is relatively small. Moreover, due to the smooth transition connection between the inner side wall and the arc surface of the annular side plate, the opening of the gap between the second support part and the bottom surface and the top surface of the annular side plate is also relatively small, so that the table top and the inner tank can be installed almost seamlessly, which can reduce the risk of residual dirt in the gap. In addition, in the water tank structure provided by the present application, the gap between the bottom surface of the second support part and the top surface of the annular side plate extends in a horizontal direction. Compared with the gap formed on the table top and extending in a vertical direction (table trough installation method), when water flows through the gap extending horizontally in the present application, the probability of dirt and accumulated water seeping into the gap is smaller, which can further reduce the risk of residual dirt.

[0019] It can be seen that the sink structure provided in the present application can not only facilitate the cleaning of accumulated water on the countertop, but also minimize the gap between the countertop and the sink, thereby avoiding dirt from remaining in the gap.

[0036] Reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application.

Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0037] In the prior art, a sink structure usually includes a sink and a countertop. The sink includes an inner tank and a circle of frame connected to the outside of the top of the inner tank, and the sink can generally be installed to the countertop through three different installation methods: above-the-counter sink installation, mid-the-counter sink installation, and under-the-counter sink installation. Among them, above-the-counter sink installation means that the inner tank is embedded in the through opening of the countertop, and the frame overlaps the upper surface of the countertop and protrudes from the upper surface of the countertop; mid-the-counter sink installation means that the inner tank is embedded in the through opening of the countertop, and the frame overlaps the embedded groove on the upper surface of the countertop and is flush with the upper surface of the countertop; under-the-counter installation means that the frame is connected to the lower surface of the countertop.

[0038] However, when the above-the-counter sink is installed, the frame of the sink protrudes from the upper surface of the countertop, and the liquid on the upper surface of the countertop cannot be smoothly transferred to the inner tank of the sink, which will cause water to remain on the countertop, and it is easy for the countertop to have residual dirt or mold; when the middle-of-the-counter sink is installed, the seam at the joint between the countertop and the sink is visible and may even open under continuous use, and the residual dirt in the seam is not easy to clean; when the under-the-counter sink is installed, the gap between the sink frame and the countertop is large, and residual dirt is easy to appear. It can be seen that the sink structure in the prior art fails to simultaneously meet the dual performance requirements of convenient cleaning of countertop water and seamless installation between the countertop and the sink.

[0039] Based on this, in order to solve the above problems, the present application designs a sink structure, which can not only facilitate the cleaning of water on the countertop, but also achieve seamless installation of the countertop and the sink.

[0040] See also Figure 1 and Figure 2 The sink structure 10 provided in the embodiment of the present application is now described. The sink structure 10 includes a sink 100 and a table 200. Figure 3 and Figure 4 The water tank 100 includes an inner tank 110 and a fixing member 120. The inner tank 110 includes a bottom plate 111 and an annular side plate 112. The annular side plate 112 is connected to the outer edge of the bottom plate 111. The annular side plate 112 and the bottom plate 111 are surrounded to form an open receiving groove 113. The fixing member 120 is fixedly connected to the outer side of the annular side plate 112. Figure 5 and Figure 6 The table top 200 includes a first supporting portion 210 and a second supporting portion 220, both of which are annular. The first supporting portion 210 is supported on the fixing member 120, and the second supporting portion 220 is connected to the inner side of the first supporting portion 210. At least part of the structure of the second supporting portion 220 is supported on the top surface of the annular side plate 112. The top surface of the second supporting portion 220 is set as an arc surface 221, and the arc surface 221 is smoothly transitioned to the top surface of the first supporting portion 210 and the inner wall of the annular side plate 112.

[0041] Specifically, the water tank 100 can be made of one or more materials such as stainless steel, brass, bronze, etc. The cross-sectional shape of the inner tank 110 of the water tank 100 can be circular, polygonal, elliptical, etc., and can be set as needed.

[0042] Specifically, the fixing member 120 can be set to a variety of structures, for example, the fixing member 120 can be set to an annular structure, the annular structure is fixedly sleeved on the outer side of the annular side plate 112, and the top surface of the annular structure is used to support the first support portion 210. For another example, the fixing member 120 can also be set to a plurality of support rods, the plurality of support rods are distributed at intervals along the circumference of the annular side plate 112, each support rod is fixed on the outer wall surface of the annular side plate 112, and the tops of the plurality of support rods jointly support the first support portion 210.

[0043] The fixing part 120 can be integrally formed with the inner liner 110, or can be separately formed from the inner liner 110. When the fixing part 120 and the inner liner 110 are separately formed, the fixing part 120 can be fixedly connected to the annular side plate 112 by one or more connection methods such as welding, threaded connection, bonding, and snap connection. Of course, the fixing part 120 can also be indirectly fixedly connected to the annular side plate 112 through other structural parts.

[0044] Specifically, the table top 200 can be made of natural stone, artificial quartz stone and other materials. The first support part 210 and the second support part 220 can be integrally formed or separately formed. When the first support part 210 and the second support part 220 are integrally formed, there is no gap between the first support part 210 and the second support part 220, and the table top 200 has high structural strength and anti-water accumulation performance.

[0045] The top surface of the second support portion 220 can be set to an arc surface or an arc surface of other shapes. When the top surface of the second support portion 220 is set to a circular arc surface, the circular arc surface can be tangent to the top surface of the first support portion 210 and the inner wall of the annular side plate 112 at the same time, which is conducive to the smooth flow of water accumulated on the table 200 into the sink 100, and is conducive to reducing the gap between the bottom surface of the second support and the top surface of the annular side plate 112.

[0046] Compared with the prior art, the sink structure 10 provided in the embodiment of the present application has an inner tank 110 including a bottom plate 111 and an annular side plate 112 connected to the outer edge of the bottom plate 111, and the outer side of the annular side plate 112 is fixedly connected with a fixing member 120, and the table top 200 includes a first supporting portion 210 and a second supporting portion 220 connected to each other, the first supporting portion 210 can be supported on the fixing member 120, the second supporting portion 220 can be supported on the annular side plate 112, and the top surface of the second supporting portion 220 is The arc surface 221 is smoothly connected to the inner wall of the annular side plate 112 and the top surface of the first support portion 210. This design allows the first support portion 210 and the top surface and the inner wall of the annular side plate 112 to be smoothly connected through the arc surface 221. The accumulated water on the first support portion 210 can flow smoothly to the inner wall of the annular side plate 112 through the arc surface 221, and it is not easy for water to accumulate on the first support portion 210. The second support portion 220 itself has a arc surface and is not easy to accumulate water.

[0047] Moreover, under the action of gravity, the bottom surface of the second support portion 220 is directly attached to the top surface of the annular side plate 112, and the height of the gap between the bottom surface of the second support portion 220 and the top surface of the annular side plate 112 is relatively small. Moreover, since the inner side wall of the annular side plate 112 and the arc surface 221 are smoothly transitionally connected, the opening of the gap between the second support portion 220 and the bottom surface and the top surface of the annular side plate 112 is also relatively small, so that the table top 200 and the liner 110 can be installed almost seamlessly, which can reduce the risk of residual dirt in the gap. In addition, in the water tank structure 10 provided in the present application, the gap between the bottom surface of the second support portion 220 and the top surface of the annular side plate 112 extends in the horizontal direction. Compared with the gap formed on the table top 200 and extending in the vertical direction (the table trough installation method), when the water flows through the gap extending horizontally in the present application, the probability of dirt and accumulated water seeping into the gap is smaller, which can further reduce the risk of residual dirt.

[0048] It can be seen that the sink structure 10 provided in the present application can not only facilitate the cleaning of the accumulated water on the countertop 200, but also minimize the gap between the countertop 200 and the sink 100 to avoid dirt from remaining in the gap.

[0049] In one embodiment, see Figure 3 and Figure 4 The fixing member 120 includes a connecting ring 121 and a supporting ring 122 which are connected to each other. The connecting ring 121 is fixedly mounted on the outer side of the annular side plate 112. The supporting ring 122 is connected to the bottom or top of the connecting ring 121 and is perpendicular to the annular side plate 112. The top surface of the supporting ring 122 is used to support the first supporting portion 210.

[0050] Specifically, the connection ring 121 and the annular side plate 112 can be fixedly connected by welding, bonding, snap connection, etc., and can be set as needed, and this embodiment does not limit this. Exemplarily, the connection ring 121 and the annular side plate 112 are fixedly connected by welding, and the connection ring 121 and the annular side plate 112 are fixedly connected by welding. The connection strength of the connection ring 121 and the annular side plate 112 is high, which is conducive to the stable connection between the countertop 200 and the sink 100.

[0051] In the sink structure 10 provided in this embodiment, the connection ring 121 is a complete annular structure, and the contact area between the connection ring 121 and the annular side plate 112 is large, which is conducive to enhancing the connection strength between the connection ring 121 and the annular side plate 112. In addition, the support ring 122 is a complete annular structure, and the support ring 122 can support each area of ​​the first support part 210 along the circumferential direction, so that the tabletop 200 and the sink 100 can be stably connected to each other, which is conducive to the tabletop 200 and the sink 100 to maintain a seamless connection state effectively for a long time.

[0052] In one embodiment, see Figure 6 The top surface of the connecting ring 121 is flush with the top surface of the annular side plate 112 , and the top surface of the connecting ring 121 and the top surface of the annular side plate 112 jointly support the second supporting portion 220 .

[0053] In this configuration, the connecting ring 121 can enhance the structural strength of the top of the annular side plate 112, reduce the risk of deformation of the annular side plate 112 during installation and use, and minimize the deformation of the annular side plate 112 from affecting the size of the gap between the annular side plate 112 and the second support portion 220.

[0054] In one embodiment, the fixing member 120 is an integrated sheet metal structure. Setting the fixing member 120 as an integrated sheet metal structure can make the fixing member 120 have higher strength and rigidity, can stably support the table 200, and can also strengthen the structure of the liner 110. In addition, the integrated sheet metal structure has higher production efficiency, better durability and lower cost.

[0055] In one embodiment, the water tank structure 10 further includes a sealant layer (not shown in the figure, the same below), and the sealant layer is at least filled between the bottom surface of the second support portion 220 and the top surface of the annular side plate 112 .

[0056] Specifically, after the sealant layer is formed between the bottom surface of the second support portion 220 and the top surface of the annular side plate 112, the outer wall of the sealant layer can be smoothly connected to the inner wall of the annular side plate 112 and the top surface of the second support portion 220 by grinding.

[0057] The sink structure 10 provided in this embodiment can block the extremely small gap between the bottom surface of the second support part 220 and the top surface of the annular side plate 112, so that the sink 100 and the countertop 200 are closer to seamless assembly, and the accumulated water on the countertop 200 can be more easily discharged into the sink 100. It can also be more conducive to avoiding the accumulation of dirt in the gap between the sink 100 and the countertop 200, thereby improving the overall performance of the sink structure 10.

[0058] In one embodiment, see Figure 7 The sink structure 10 further includes a connection assembly 300, which includes a threaded connector 310, a nut 320 and a fastener 330. One end of the threaded connector 310 is fixedly connected to the bottom of the first support portion 210, and the fastener 330 is sleeved on the threaded connector 310. The nut 320 is threadedly connected to the threaded connector 310 and is located on the side of the fastener 330 away from the first support portion 210, so that the two ends of the fastener 330 are respectively abutted against the bottom of the fixing member 120 and the bottom of the first support portion 210. In this way, it is equivalent to that one end of the connection assembly 300 is fixedly connected to the first support portion 210, and the other end of the connection assembly 300 and the second support portion 220 jointly clamp and fix the fixing member 120, so that the countertop 200 is not only supported on the sink 100, but also fixedly connected to the sink 100, which is conducive to the second support portion 220 of the countertop 200 and the annular side plate 112 of the sink 100 to maintain a seamless splicing state for a long time.

[0059] In one embodiment, see Figure 7The threaded connector 310 includes a rod 312 and a head 311 connected to each other, the head 311 is bonded to the bottom surface of the first support part 210, and the rod 312 is used for the fastener 330 to be sleeved and threadedly connected to the nut 320. In this way, the threaded connector 310 and the first support part 210 can be fixedly connected more conveniently, and the bonding method will not damage the structure of the first support part 210, so that the table top 200 can maintain a high structural strength.

[0060] In one embodiment, see Figure 7 The fastener 330 includes a first bending section 331, a second bending section 332 and a third bending section 333 which are bent and connected in sequence. The second bending section 332 is sleeved on the threaded connector 310 and has elasticity. One end of the first bending section 331 away from the second bending section 332 abuts against the bottom of the fixing member 120, and one end of the third bending section 333 away from the second bending section 332 abuts against the bottom of the first support portion 210.

[0061] Specifically, the first bending section 331, the second bending section 332 and the third bending section 333 of the fastener 330 can be formed as one piece or separately. In addition to the second bending section 332 having elastic deformation capability, the first bending section 331 and the third bending section 333 can also be set as structural parts with elastic deformation capability.

[0062] The sink structure 10 provided in this embodiment has a fastener 330 comprising a first bending section 331, a second bending section 332 and a third bending section 333 which are bent and connected in sequence. When the nut 320 pushes the fastener 330 upward, the second bending section 332 can be slightly deformed, so that the first bending section 331 can abut against the bottom of the fixing member 120 having a slightly different thickness and / or height, and the third bending section 333 can abut against the bottom of the first supporting portion 210 having a slightly different thickness and / or height, which is beneficial to reducing the processing accuracy and assembly accuracy requirements of the components of the sink structure 10.

[0063] In one embodiment, see Figure 3 and Figure 4 The fixing member 120 is an annular structure, and the number of the connecting components 300 is multiple, and the multiple connecting components 300 are arranged at intervals along the circumference of the fixing member 120.

[0064] It should be noted that each connecting assembly 300 includes a bolt, a nut 320 and a fastener 330. The multiple bolts are arranged at intervals along the circumference of the first support portion 210. The top of each bolt is fixedly connected to the bottom of the first support portion 210. Each fastener 330 is respectively mounted on the corresponding bolt, and each nut 320 is respectively threadedly connected to the corresponding bolt, so that the two ends of the corresponding fastener 330 are respectively abutted against the bottom of the fixing member 120 and the bottom of the first support portion 210.

[0065] The sink structure 10 provided in this embodiment has a plurality of connection components 300 that can form a plurality of connection points between the first support portion 210 and the fixing member 120. At each connection point, the first support portion 210 and the fixing member 120 are connected to each other, and the plurality of connection points are distributed at intervals along the circumference of the first support portion 210. In this way, the first support portion 210 can be stably connected to the fixing member 120, thereby enabling the countertop 200 and the sink 100 to be stably connected to each other.

[0066] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
