Description

Technical Field

[0001] This invention relates to a sink system, and more specifically, to a stress-supported, single-pool, wear-resistant, multi-functional sink system comprising a sink with a variety of features designed to provide enhanced functionality for such sinks. Background Technology

[0002] Traditional kitchen sinks often feature steps on their inner surface. These steps are used to suspend plate-like components, such as for cutting food. Therefore, the space at the sink opening can be effectively used as a workspace. However, simply adding plate-like components to the steps can lead to space constraints as cooking and other tasks increase. For example, while significant weight or pressure may be added when cutting food or using it as a dehydrator, it is generally not needed when simply placing food or cooking utensils. In such cases, the design of the steps for multiple uses has not been adequately considered, nor has the design addressed different aspects of the steps based on weight or pressure.

[0003] Common problems with stepped sinks that fall include improper flange placement within the pre-cut countertop, gaps between the flange and the countertop, insufficient bonding strength between the sidewalls, and inadequate flange support for the sink's weight. For example, Japanese Patent JP7176831B2 and US Patent US12247378B2 disclose a single-sink type sink comprising a base plate and four sidewalls: two long sidewalls and two short sidewalls, welded together. Multiple steps are provided on the inner surface of the two long sidewalls for placing plate-like components. Because these steps are rectangular (i.e., all steps are the same width), direct welding between the long and short sidewalls, and the lack of reinforcement on the outer wall of the sink, gaps arise between the flange and the countertop, and between the sidewalls. The existing sink technologies in these two patents involve traditional steps with a uniform width extending along the long sidewalls. These steps do not provide sufficient support to the short sidewalls, and there are no external reinforcement components for the sidewalls, steps, or flanges. This results in insufficient strength for these traditional sinks. During use, heavy components such as faucets must be installed on top of the sink, making them prone to cracking between the sidewalls and detachment from the countertop. Furthermore, the sink panels lack the press-fit flange structure found in stretch sinks to enhance overall support. Due to the lack of stress-supporting structures during product transportation, the panels are prone to deformation and bending, leading to poor fit to the countertop during installation, or even severe deformation that may prevent installation altogether. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a stress-supported single-pool wear-resistant multifunctional water tank system.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stress-supported single-pool wear-resistant multifunctional sink system, comprising a single-pool basin, a faucet housing, a main faucet, a purified water faucet, a cup washer, a soap dispenser, a waterfall water outlet assembly, and a spray water outlet assembly. The main faucet, purified water faucet, cup washer, soap dispenser, waterfall water outlet assembly, and spray water outlet assembly are installed on the faucet housing. The waterfall water outlet assembly includes strip-shaped waterfall nozzles, through which water forms a waterfall shape and sprays into the single-pool basin. The spray water outlet assembly includes dotted nozzle holes, through which water forms a raindrop shape and sprays into the single-pool basin. The single-pool basin... The body includes a rectangular water tank and a rectangular flanged panel. The faucet box is installed on the flanged panel. The rectangular water tank is formed by bending and welding a single stainless steel plate. The inner wall of the rectangular water tank has a textured surface, while the outer wall is smooth. The rectangular water tank includes a base plate. A first vertical long side plate, a second vertical long side plate, a first vertical short side plate, and a second vertical short side plate are integrally bent and connected upwards around the base plate. The first vertical long side plate, the first vertical short side plate, the second vertical long side plate, and the second vertical short side plate are sequentially welded together to form a rectangular cylindrical side section. Inside the single-pool basin, there are folded first prestressed steps and second prestressed steps.

[0006] The first prestressed step includes:

[0007] The first prestressed horizontal step wall panel is formed by bending the upper end of the first vertical long side panel outward by 90 degrees. The first prestressed horizontal step wall panel connects the first vertical long side panel with the first vertical short side panels and the second vertical short side panels on both sides in a prestressed reinforced connection. The first prestressed horizontal step wall panel includes a first middle rectangular wall panel and a first arc-shaped stress connection part and a second arc-shaped stress connection part integrally connected to its two sides. The first prestressed horizontal step wall panel is bent inward into the water tank on both sides to form the first arc-shaped stress connection part and the second arc-shaped stress connection part.

[0008] The first vertical connecting wall panel is formed by bending the end of the first prestressed horizontal step wall panel upwards by 90 degrees;

[0009] The second prestressed step includes:

[0010] The second prestressed horizontal step wall panel is formed by bending the upper end of the second vertical long side panel outward by 90 degrees. The second prestressed horizontal step wall panel connects the second vertical long side panel with the first vertical short side panels and the second vertical short side panels on both sides in a prestressed reinforced connection. The second prestressed horizontal step wall panel includes a second middle rectangular wall panel and a third arc-shaped stress connection part and a fourth arc-shaped stress connection part integrally connected to its two sides. The second prestressed horizontal step wall panel is bent inward into the water tank on both sides to form the third arc-shaped stress connection part and the fourth arc-shaped stress connection part.

[0011] The second vertical connecting wall panel is formed by bending the end of the second prestressed horizontal step wall panel upwards by 90 degrees;

[0012] The two arc-shaped stress connection parts of the prestressed horizontal step wall panel are on the same horizontal plane as the middle rectangular wall panel. The two arc-shaped stress connection parts protrude and extend towards the opposite vertical long side plate relative to the middle rectangular wall panel, so that the prestressed horizontal step wall panel forms an arc-shaped double L shape. The four arc-shaped stress connection parts of the two prestressed horizontal step wall panels cause the rectangular water tank to generate stress towards the center of the water tank.

[0013] Furthermore, the preferred method of this water tank system is to connect a vertical reinforcing wing to each of the two outer corners of the water tank on the side of the wide convex edge of the flange panel on the single-pool basin. The vertical reinforcing wing is close to the first arc-shaped stress connection part and the second arc-shaped stress connection part. The vertical reinforcing wing strengthens and connects the first prestressed step and the wide convex edge of the flange panel together.

[0014] Furthermore, the preferred configuration of this water tank system is that the central rectangular wall panel includes an inner straight connecting end integrally connected to the vertical long side panel and an outer straight connecting end integrally connected to the vertical connecting wall panel, with the inner and outer straight connecting ends arranged in parallel; the arc-shaped stress connection part includes an outer arc-shaped end, a horizontal straight side end, and an inner arc-shaped end connected sequentially, and the two sides of the prestressed horizontal step wall panel are bent into the water tank in an arc shape to form an arc-shaped stress connection part, thereby forming an outer arc-shaped end and an inner arc-shaped end with prestress, which achieves a staggered protrusion connection towards the center position of the water tank when the inner wall of the vertical long side panel and the vertical short side panel are welded together.

[0015] Furthermore, the preferred method of this water tank system is to use stainless steel sheets with a double-notch structure for the vertical reinforcing fins. The vertical reinforcing fins include mutually perpendicular vertical connecting ends and horizontal connecting ends. A square connecting notch is provided on the inner end of the vertical reinforcing fins to separate the vertical connecting ends and the horizontal connecting ends. The square connecting notch matches the size of the prestressed horizontal step wall panel on the vertical long side plate. An arc-shaped notch is provided on the outer end of the vertical reinforcing fins.

[0016] Furthermore, the preferred method of this water tank system is that the square connection notch includes mutually perpendicular step transverse connection ends, step vertical connection ends, wing vertical connection ends, step transverse connection ends, step vertical connection ends, wing transverse connection ends, and the arc-shaped end of the arc-shaped notch are connected sequentially. When the vertical reinforcing wing is welded to the rectangular water tank and the rectangular flange panel, the wing vertical connection end is welded to the outer wall of the vertical long side plate of the rectangular water tank, the step transverse connection end is welded to the outer wall of the prestressed horizontal step wall panel on the vertical long side plate, and the step vertical connection end is welded to the vertical connection wall panel on the vertical long side plate.

[0017] Furthermore, the preferred method of this water tank system is to have square protruding lugs extending outward from both sides of the upper end of the vertical short side plate, so that the two sides of the vertical short side plate respectively form a first vertical end, a horizontal end, and a second vertical end of the short side plate. The first vertical end and the second vertical end of the short side plate are bent into a first upper R-rounded corner connecting edge and a first lower R-rounded corner connecting edge, respectively. On both sides of the vertical connecting wall panel of the vertical long side plate, the sides are bent into second upper R-rounded corner connecting edges. On both sides of the vertical long side plate below the prestressed horizontal step wall panel, the sides are bent into... The second lower R-rounded corner is bent to form the connecting edge; when welding the vertical long side plate and the vertical short side plate, the first upper R-rounded corner connecting edge and the second upper R-rounded corner connecting edge are welded to form the upper R-rounded corner connecting part, and the horizontal end of the short side plate is welded to the horizontal straight end of the vertical long side plate to form the middle step connecting part. The first lower R-rounded corner connecting edge and the second lower R-rounded corner connecting edge are welded to form the lower R-rounded corner connecting part. The lower R-rounded corner connecting part is closer to the center of the water tank than the upper R-rounded corner connecting part, forming a staggered arrangement. The upper R-rounded corner connecting part and the lower R-rounded corner connecting part form a staggered stepped connecting structure. Attached Figure Description

[0035] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0036] The following is in conjunction with the appendix Figure 1-17 The present invention will be further described in detail with reference to specific embodiments:

[0037] like Figure 1 , Figure 2 , Figure 13 The description includes a sink system 100 (e.g., a kitchen sink system, a countertop sink system), which includes a single-bowl basin 1, a faucet housing 2, a main faucet 3, a purified water faucet 4, a cup washer 5, a soap dispenser 6, a waterfall water outlet assembly 7, a spray water outlet assembly 8, a water temperature regulating valve, and a water distributor.

[0038] A washing drain hole is provided at the bottom of the single-basin basin 1. The single-basin basin 1 includes a rectangular sink 11, a flange panel 12 connecting the top of the rectangular sink 11, and an adjustable sink mounting and locking device 200. The faucet box 2 is installed on the flange panel 12. The faucet box 2 is equipped with a main faucet 3, a purified water faucet 4, a cup washer 5, a soap dispenser 6, a waterfall water outlet assembly, a spray water outlet assembly, a water temperature regulating valve, and a water distributor. The adjustable sink mounting and locking device 200 can securely install the single-basin basin 1 into the sink mounting hole of the kitchen mounting panel.

[0039] The water temperature regulating valve is connected to the cold and hot water inlet pipes. The water inlet of the distributor is connected to the output of the water temperature regulating valve. The distributor has multiple outlets, which are respectively connected to the main faucet 3, the cup washer 5, the waterfall water outlet assembly 7, and the spray water outlet assembly 8. The purified water faucet 4 is connected to the purified water machine separately, which is convenient to use. The soap dispenser 6 is connected to the detergent container in the cabinet. Since it is adjacent to the water source, it is convenient to use.

[0040] The faucet box 2 includes a bottom box 21 with an opening at the top and a top cover plate 22. The top cover plate 22 is made of transparent or semi-transparent glass or plastic material. The bottom box 2 is made of aluminum alloy plate, stainless steel plate or copper alloy plate. The bottom wall plate of the bottom box 21 is fixed on the flange panel 12. The bottom wall plate of the bottom box 21 and the flange panel 12 are respectively provided with mounting holes for the main faucet 3, the purified water faucet 4, the cup washer 5, and the soap dispenser 6. The waterfall water outlet component, the spray water outlet component and the water temperature regulating valve are all set inside the bottom box 21. The front wall plate of the bottom box 21 is provided with a waterfall mounting hole 23, a spray mounting hole 24 and a button hole.

[0041] To save installation space in the faucet housing 2 and for ease of use and operation, the waterfall mounting hole 23 and the spray mounting hole 24 are respectively located on the left and right sides of the front wall panel of the base box 21. The cup washer 5 is located to the left of the waterfall mounting hole 23, and the soap dispenser 6 is located directly above the waterfall mounting hole 23. Four button holes are arranged close together between the waterfall outlet hole 23 and the spray mounting hole 24. These four button holes contain combination buttons 9 that control the water flow of the cup washer 5, the waterfall water outlet assembly 7, the main faucet 3, and the spray water outlet assembly 8, and are arranged side-by-side. A separate button hole is located to the right of the spray water outlet hole 24, containing a purified water button 90 that controls the purified water flow of the purified water faucet 4.

[0042] The waterfall water outlet component 7 includes a strip waterfall water outlet head 71, which is installed on the waterfall water outlet hole 23. The strip waterfall water outlet head 71 has a horizontal strip water outlet hole. When the waterfall button in the combination button is turned on, the waterfall water outlet component 7 is turned on to supply water. Water flows through the horizontal strip water outlet hole of the strip waterfall water outlet head 71 to form a waterfall shape and spray water into the water tank.

[0043] The spray water outlet assembly 8 includes a spray plate 81 mounted on the spray mounting hole 24 and dot-shaped nozzle holes 82 provided on the spray plate 81. The dot-shaped nozzle holes 82 are arranged in several rows, with adjacent rows staggered. When the spray button in the combination key is turned on, the water source of the spray water outlet assembly 8 is turned on, and the water is sprayed into the water tank in a rain-like shape through the dot-shaped nozzle holes 81.

[0044] like Figure 1 , Figure 2 , Figure 9As shown, the single-pool basin 1 is rectangular in shape, comprising a rectangular water tank 11 and a rectangular flanged panel 12. The rectangular water tank 11 is formed by bending and welding a single stainless steel plate. The rectangular water tank 11 includes a base plate 101, around which a first vertical long side plate 102, a second vertical long side plate 103, a first vertical short side plate 104, and a second vertical short side plate 105 are integrally connected by bending upwards. These three vertical long side plates 102, 104, 103, and 105 are sequentially welded together to form a rectangular cylindrical side section. The first vertical long side plate 102 and the second vertical long side plate 103 are of the same length and face each other, as are the first vertical short side plate 104 and the second vertical short side plate 105. The length of the first vertical long side plate 102 is greater than the length of the first vertical short side plate 104. The flange panel 12 is formed by cutting a central groove from another stainless steel plate. The flange panel 12 is rectangular, and its overall size is larger than that of the rectangular sink 11. When the flange panel 12 is fixed to the top surface of the rectangular sink 11, it forms four flanges that can be installed on the kitchen countertop. One of the flanges is a wide flange 121, which is significantly wider than the other three flanges. The faucet box 2 is installed on the wide flange 121. Preferably, the flange panel 12 is directly connected to the top of the first vertical long side plate 102, the second vertical long side plate 103, the first vertical short side plate 104, and the second vertical short side plate 105 by welding.

[0045] like Figure 1 , Figure 2 , Figure 9 To enhance the load-bearing strength of the single-pool basin 1, reinforced structures are provided both inside and outside the single-pool basin 1. A pair of prestressed steps are folded and machined inside the single-pool basin 1, namely the first prestressed step 110 and the second prestressed step 111. The first prestressed step 110 provides a prestressed reinforced connection between the first vertical long side plate 102 and the first vertical short side plates 104 and 105 on both sides. The second prestressed step 111 provides a prestressed reinforced connection between the second vertical long side plate 103 and the first vertical short side plates 104 and 105 on both sides, ensuring that all four interior corners of the single-pool basin 1 are prestressed.

[0046] At each of the two outer corners of the wide convex edge 121 on one side of the single-pool basin 1, a vertical reinforcing wing 13 is connected. The vertical reinforcing wing 13 strengthens and connects the first prestressed step and the wide convex edge 121 of the flange panel 12 together. By simultaneously providing reinforced stress-bearing structures inside and outside the single-pool basin 1, the overall support of the basin is enhanced, making the stress-bearing strength of the integrated single-pool basin 1 more than twice that of ordinary basins currently on the market. During use, even when installing heavy components such as faucets, the strong stress-bearing capacity and prestress prevent cracks caused by weak welding between the vertical side panels, and also prevent the basin from detaching from the mounting surface. Furthermore, during product transportation, the basin of this invention, due to its internal and external reinforced stress-bearing structure, prevents the vertical side panels from deforming or bending relative to the base plate, ensuring that the product fits well against the cabinet mounting surface during installation and guaranteeing product stability.

[0047] like Figure 3-5 , Figure 8-9 As shown, the first prestressed step 110 includes a first prestressed horizontal step wall panel 102a and a first vertical connecting wall panel 102b. The first prestressed horizontal step wall panel 102a is formed by bending outwards at a 90-degree angle from the upper end of the first vertical long side panel 102. The first prestressed horizontal step wall panel 102a is then bent upwards at a 90-degree angle to form the first vertical connecting wall panel 102b. The first prestressed horizontal step wall panel 102a has an overall double "L" shape. Preferably, the first prestressed horizontal step wall panel 102a includes a first middle rectangular wall panel 102c and a first arc-shaped stress connection part 102d and a second arc-shaped stress connection part 102e integrally connecting its two sides. The first prestressed horizontal step wall panel 102a is curved inwards towards the water tank on both sides to form the first arc... The first arc-shaped stress connection part 102d and the second arc-shaped stress connection part 102e are on the same horizontal plane as the first intermediate rectangular wall panel 102c. The first arc-shaped stress connection part 102d and the second arc-shaped stress connection part 102e have the same structure and are symmetrically arranged. The first arc-shaped stress connection part 102d and the second arc-shaped stress connection part 102e protrude and extend relative to the first intermediate rectangular wall panel 102c towards the second vertical long side panel 103, so that the first arc-shaped stress connection part 102d and the second arc-shaped stress connection part 102e protrude beyond the first intermediate rectangular wall panel 102c. The first prestressed horizontal step wall panel 102a forms a double L shape with arcs on both sides. The first intermediate rectangular wall panel 102c includes a first inner straight connecting end 102c1 integrally connected to the first vertical long side panel 102, and a first outer straight connecting end 102c2 integrally connected to the vertical connecting wall panel 102b. The first inner straight connecting end 102c1 and the first outer straight connecting end 102c2 are arranged in parallel.

[0048] like Figure 4 The first arc-shaped stress connection portion 102d includes a first outer arc-shaped end 102d1, a first horizontal straight side end 102d2, and a first inner arc-shaped end 102d3 connected sequentially. For example... Figure 5 The second arc-shaped stress connection 102e includes a second outer arc-shaped end 102e1, a second horizontal straight side end 102e2, and a second inner arc-shaped end 102e3 connected sequentially. The distance between the first inner straight connection end 102c1 and the first outer straight connection end 102c2 is D1 cm, the distance between the first outer arc-shaped end 102d1 and the first inner arc-shaped end 102d3 is D2 cm, and the distance between the second outer arc-shaped end 102e1 and the second inner arc-shaped end 102e3 is D3 cm. The distances D1, D2, and D3 are equal. The first horizontal straight side end 102d2 and the second horizontal straight side end 102e2 are parallel and perpendicular to the first inner straight connection end 102c1 and the first outer straight connection end 102c2. The first horizontal straight side end 102d2 and the second horizontal straight side end 102e2 are welded to the inner walls of the first vertical short side plate 104 and the second vertical short side plate 105, respectively. Because the first prestressed horizontal step wall panel 102a bends inwards into the water tank on both sides to form the first arc-shaped stress connection part 102d and the second arc-shaped stress connection part 102e, it forms an outer arc-shaped end and an inner arc-shaped end with prestress. In this way, when the first vertical long side plate 102 is welded to the inner wall of the first vertical short side plate 104 and the second vertical short side plate 105, a staggered protrusion connection towards the center of the water tank is achieved, which not only provides prestress but also improves the multi-dimensional connection strength.

[0049] like Figure 3-5 , Figure 8-9As shown, the structure of the second prestressed step 111 of the second vertical long side plate 103 is the same as the structure of the first prestressed step 110 of the first vertical long side plate 102. Specifically, the second prestressed step 111 includes a second prestressed horizontal step wall plate 103a and a second vertical connecting wall plate 103b; the upper end of the second vertical long side plate 103 is bent outward by 90 degrees to form the second prestressed horizontal step wall plate 103a, and the second prestressed horizontal step wall plate 103a is bent upward by 90 degrees to form the second vertical connecting wall plate 103b. The second prestressed horizontal step wall plate 103a is generally shaped like a double "L". Preferably, the second prestressed horizontal step wall plate 103a includes a second middle rectangular wall plate 103c and a third arc-shaped stress connection part 103d and a fourth arc-shaped stress connection part 103e integrally connecting its two sides. The two sides of the second prestressed horizontal step wall plate 103a are curved inward into the water tank to form the third The arc-shaped stress connection 103d, the fourth arc-shaped stress connection 103e, the third arc-shaped stress connection 103d, the fourth arc-shaped stress connection 103e and the second intermediate rectangular wall panel 103c are on the same horizontal plane. The third arc-shaped stress connection 103d and the fourth arc-shaped stress connection 103e have the same structure and are symmetrically arranged. The third arc-shaped stress connection 103d and the fourth arc-shaped stress connection 103e protrude from the second intermediate rectangular wall panel 103c towards the first vertical long side panel 102, so that the third arc-shaped stress connection 103d and the fourth arc-shaped stress connection 103e protrude from the second intermediate rectangular wall panel 103c. The second prestressed horizontal step wall panel 103a forms a double L-shaped arc on both sides. The second intermediate rectangular wall panel 103c includes a second inner straight connecting end 103c1 integrally connected to the second vertical long side panel 103, and a second outer straight connecting end 103c2 integrally connected to the vertical connecting wall panel 103b. The second inner straight connecting end 103c1 and the second outer straight connecting end 103c2 are arranged in parallel.

[0050] like Figure 6 The third arc-shaped stress connection 103d includes a third outer arc-shaped end 103d1, a third horizontal straight side end 103d2, and a third inner arc-shaped end 103d3 connected sequentially. For example... Figure 7The fourth arc-shaped stress connection 103e includes a fourth outer arc-shaped end 103e1, a fourth horizontal straight side end 103e2, and a fourth inner arc-shaped end 103e3 connected sequentially. The distance between the second inner straight connection end 103c1 and the second outer straight connection end 103c2 is D1 cm, the distance between the third outer arc-shaped end 103d1 and the third inner arc-shaped end 103d3 is D2 cm, and the distance between the fourth outer arc-shaped end 103e1 and the fourth inner arc-shaped end 103e3 is D3 cm. The distances D1, D2, and D3 are equal. The third horizontal straight side end 103d2 and the fourth horizontal straight side end 103e2 are arranged in parallel and are both perpendicular to the second inner straight connection end 103c1 and the second outer straight connection end 103c2. The third horizontal straight side end 103d2 and the fourth horizontal straight side end 103e2 are welded to the inner walls of the first vertical short side plate 104 and the second vertical short side plate 105, respectively. Because the second prestressed horizontal step wall panel 103a bends inwards into the water tank on both sides to form the third arc-shaped stress connection part 103d and the fourth arc-shaped stress connection part 103e, it forms an outer arc-shaped end and an inner arc-shaped end with prestress. In this way, when the second vertical long side plate 103 is welded to the inner wall of the first vertical short side plate 104 and the second vertical short side plate 105, a staggered protrusion connection towards the center of the water tank is achieved, which not only provides prestress but also improves the multi-dimensional connection strength.

[0051] Through the first arc-shaped stress connection part 102d and the second arc-shaped stress connection part 102e of the first prestressed horizontal step wall panel 102a, and the third arc-shaped stress connection part 103d and the fourth arc-shaped stress connection part 103e of the second prestressed horizontal step wall panel 103a, these four arc-shaped stress connection parts generate stress towards the center of the rectangular sink 11. When subjected to external force, it can have sufficient prestress to prevent the vertical side panel from deforming and bending relative to the bottom plate, ensuring that the product can fit well with the cabinet countertop during installation and guaranteeing the stability of the product.

[0052] like Figure 10-12As shown, the vertical reinforcing wing 13 is positioned at the outer corner of the single-pool basin 1, close to the first arc-shaped stress connection portion 102d and the second arc-shaped stress connection portion 102e. The vertical reinforcing wing 13 preferably has a double-notch structure made of stainless steel. The vertical reinforcing wing 13 includes mutually perpendicular vertical connecting ends 131 and lateral connecting ends 132. A square connecting notch 133 is provided at the inner end of the vertical reinforcing wing 13, separating the vertical connecting ends 131 and lateral connecting ends 132. The square connecting notch 133 matches the dimensions of the outer wall of the steps on the first vertical long side plate 102 and the second vertical long side plate 103. An arc-shaped notch 134 is provided at the outer end of the vertical reinforcing wing 13. The square connection notch 133 includes mutually perpendicular step transverse connection end 1331, step vertical connection end 1332, wing vertical connection end 131, step transverse connection end 1331, step vertical connection end 1332, wing transverse connection end 132, and the arc-shaped end of the arc-shaped notch 134 connected in sequence.

[0053] like Figure 10-12 As shown, when the vertical reinforcing wing 13 is welded to the rectangular water tank 11 and the rectangular flange panel 12, the vertical connecting end 131 of the wing is welded to the outer wall of the vertical long side plate of the rectangular water tank 11, such as welding to the outer wall of the first vertical long side plate 102. The lateral connecting end 1331 of the step is welded to the outer wall of the prestressed horizontal step wall panel on the vertical long side plate, such as welding to the outer wall of the first prestressed horizontal step wall panel 102a on the first vertical long side plate 102; the vertical connecting end 1332 of the step is welded to the vertical connecting wall panel on the vertical long side plate, such as welding to the first vertical connecting wall panel 102b on the first vertical long side plate 102. The lateral connecting end 132 of the wing is welded to the flange panel 12, such as welding to the wide convex edge 121.

[0054] The square connecting notch 133 of the vertical reinforcing wing 13 ensures a tight fit between the vertical reinforcing wing 13 and the vertical long side plate, prestressed step, and flange panel. Simultaneously, the presence of the arc-shaped notch 134 increases the external support stress of the single-pool basin 1. This product, through internal and external stress generation points, forms a double prestressed reinforcement structure, increasing the flexibility of the single-pool basin 1's elastic deformation. This prevents excessive structural rigidity from causing stress deformation, resulting in a more stable structure and preventing damage to splicing or welding structures due to excessive stress, thus extending its service life.

[0055] like Figure 3-7To further enhance the strength of the entire single-pool basin 1, the side plates of the rectangular water tank 11 are connected by two vertically staggered sections. Square protruding lugs 1045 extend outwards from both sides of the upper ends of the first vertical short side plate 104 and the second vertical short side plate 105, respectively, forming a first vertical end, a horizontal end, and a second vertical end of the short side plate. The first vertical end and the second vertical end of the short side plate are bent into a first upper rounded corner connecting edge 1045a and a first lower rounded corner connecting edge 1045b, respectively. Both sides of the first vertical connecting wall panel 102b of the first vertical long side plate 102 and the upper ends of both sides of the second vertical connecting wall panel 103b of the second vertical long side plate 103 are bent into second upper R rounded corner connecting edges 1023a; the first vertical long side plate 102 and the second vertical long side plate 103 are bent into second upper R rounded corner connecting edges 1023a. Both sides of the wall below the prestressed horizontal step are bent into second lower R-rounded corner connecting edges 1023b. When welding the long side plate to the short side plate, the first upper R-rounded corner connecting edge 1045a and the second upper R-rounded corner connecting edge 1023a are rolled together to form an upper R-rounded corner connecting part 14. The transverse end of the short side plate is welded to the horizontal straight ends of the first vertical long side plate 102 and the second vertical long side plate 103 to form an intermediate step connecting part, such as welding to the first horizontal straight end 102d2, the second horizontal straight end 102e2, the third horizontal straight end 103d2, and the fourth horizontal straight end 103e2. The first lower R-rounded corner connecting edge 1045b and the second lower R-rounded corner connecting edge 1023b are rolled together to form a lower R-rounded corner connecting part 15. The lower R-rounded corner connecting part 15 is closer to the center of the water tank than the upper R-rounded corner connecting part 14, forming a staggered arrangement. The upper rounded corner connecting part 14, the middle step connecting part, and the lower rounded corner connecting part 15 form a staggered step connection structure consisting of three segments: vertical, horizontal, and vertical. During the process of bending the two sides of the first vertical long side plate 102 and the second vertical long side plate 103 into the second lower rounded corner connecting edge, the first prestressed horizontal step wall plate 102a and the second horizontal step wall 103a are bent into a prestressed double "L" shape.

[0056] Reference Figure 13-17The present invention also includes an adjustable mounting and locking device 200 for locking the single-pool basin 1 to the mounting panel. The adjustable mounting and locking device includes a hook 16 fixed to the bottom of the flange panel 12 and an adjustable fixing component 17 disposed on the hook 16. A hanging hole is provided on the hook 16. The adjustable fixing component 17 includes a fixing bracket 171, a panel locking fastener 172 that can be raised and lowered and connected to the fixing bracket 171, and a bendable elastic support piece 173 connected to the fixing bracket 171. The bendable elastic support piece 173 is a smoothly bendable elastic element whose bottom is fixed to the fixing bracket 171 and whose top can abut against the step of the single-pool basin 1. Its strength is much less than that of the fixing bracket 171. It is made of a metal sheet that is thinner than the bracket and has a certain strength to provide support. With a little force, it can be bent to adjust and abut against the position of the single-pool basin 1.

[0057] The top of the fixed bracket 171 has a barb 174, which can be hooked into the hanging hole on the hook 16, allowing the fixed bracket 171 to be stably attached to the hook 16. The fixed bracket 171 has a vertical fixed wall and a horizontal fixed wall extending outward from the vertical fixed wall. The bottom of the bendable elastic support piece 173 is fixed to the vertical fixed wall of the fixed bracket 171. The panel locking fastener 172 includes a rotating bolt threaded to the horizontal fixed wall and a locking tray with upward-facing spikes rotatably fixed to the top of the rotating bolt.

[0058] When installing a stainless steel sink, securely attach the fixing bracket 171 to the hook 16, and place the top of the flexible support piece 173 against the step of the single-pool basin 1. Then, rotate the screw to raise it until the serrated edge of the locking tray is securely locked onto the mounting panel, thus firmly fixing the stainless steel sink to the mounting panel. When the width of the mounting flange panel 12 is different, or if it is not tightly secured to the mounting panel, the shape of the flexible support piece 173 can be adjusted by bending to widen or narrow it to accommodate flange panels 12 of different widths. This mounting locking mechanism allows for stable support on sinks with different flange panel 12 sizes.

[0059] like Figure 1 The single-pool basin 1 of the present invention is made of a single-sided scratch-resistant stainless steel plate, that is, the inner walls of the bottom plate 101, the first vertical long side plate 102, the second vertical long side plate 103, the first vertical short side plate 104, and the second vertical short side plate 105 are all provided with concave and convex texture patterns, while the outer wall is flat. Figure 1Only the raised and recessed texture pattern of the base plate 101 is shown. Existing embossing techniques involve cold pressing of finished stainless steel sheets to create double-sided textures. This results in textured surfaces on the outer wall of the stainless steel sink, which is not only unsightly but also makes it difficult to securely install sound insulation pads on the outer wall. The present invention utilizes an embossing machine to hot-press a single-sided texture onto the stainless steel sheet. Instead of directly embossing, the machine participates in the stainless steel sheet manufacturing process. During the annealing process, while the stainless steel sheet is still slightly damp, the embossing machine hot-presses the sheet while it is still warm. The embossing machine includes a pair of rollers, one for embossing and the other for smoothing. The embossing roller has raised and recessed textures on its surface, while the smoothing roller has a smooth surface without any texture. When using such an embossing machine to hot-press the stainless steel sheet, the sheet is still hot and has a certain degree of flexibility. The embossing roller creates fine raised and recessed textures on the upper surface of the stainless steel sheet, while the smoothing roller prevents deformation of the lower surface, ensuring that the lower surface remains smooth and free of textures. This results in a single-sided embossed pattern, with a honeycomb pattern being the preferred design. The purpose of embossing is to address the insufficient strength caused by the thinning of the bottom sheet metal after stretching the sink, and also to modify the acoustic structure of the sink bottom, providing noise reduction when water flows from the faucet or when dishes fall to the bottom. Furthermore, the raised area on the bottom of the sink prevents the bottom surface from being easily scratched by ceramic bowls, metal utensils, and other tableware after use, thus solving the problem of easy scratching.

[0060] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any modifications or variations made by those skilled in the art, without departing from the scope of the present invention, using the disclosed technical content, are equivalent embodiments of the present invention. Therefore, all equivalent changes made based on the concept of the present invention without departing from the scope of the present invention should be covered within the protection scope of the present invention.
