Description

Technical Field

[0001] This utility model relates to the field of kitchen cleaning equipment technology, and in particular to a concealed sink and its installation structure. Background Technology

[0002] The existing installation methods for kitchen sinks are mainly divided into two types: countertop and undermount.

[0003] When installing a countertop sink, a ring of sealant is usually applied at the joint to prevent water from seeping into the cabinet through the gap between the sink and the countertop. However, after a period of use, this sealant may not only change color but also become moldy or turn black due to the penetration of food residue.

[0004] In contrast, while undermount sink installations avoid exposing the sealant directly to the countertop, they cannot conceal the thickness of the cabinet countertop edges. Therefore, the sink needs to be recessed to accommodate the overall thickness of the countertop, and the thickness of the countertop edges cannot be hidden.

[0005] like Figure 1 As shown, under-counter sink installation involves fixing the outer edge of the sink to the bottom of the countertop from the bottom up, achieving a borderless installation. However, users can see the thicker edges of the countertop when cleaning, resulting in a visually heavy and unsightly appearance.

[0006] Therefore, there is an urgent need to improve existing technology and provide a sink product that conceals the thickness of the countertop. Utility Model Content

[0007] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a concealed sink that optimizes the appearance through an angled edge design while ensuring the flexibility of undermount installation; fastening components and reinforcing strips enhance the stability of the sink body.

[0008] The objective of this utility model is achieved through the following technical solution: a concealed sink, comprising a sink body, a reinforcing strip, and a fastening assembly for fixing the sink body under a countertop. The sink body has a downwardly and outwardly inclined edge strip around its opening, corresponding to the inclined edge of the countertop. The reinforcing strip is an L-shaped right-angled strip placed below the inclined strip. The first right-angled surface of the reinforcing strip connects to the outer surface of the sink body, and one end connects to the suspended end of the inclined strip, forming a right-angled triangular structure around the opening of the sink body. The fastening assembly includes a screw, a pressure plate, and a nut. The screw is used to be positioned under the countertop. The pressure plate passes through the screw and abuts against the second right-angled surface of the reinforcing strip. The nut is screwed into the screw to fix the pressure plate.

[0009] Compared with existing technologies, the concealed sink of this utility model has at least the following beneficial effects:

[0010] 1) A right-angled triangular structure is formed on the outer periphery of the opening of the sink body by means of beveled strips and reinforcing strips. It matches and connects with the countertop with beveled edge, thereby hiding the thickness of the countertop, optimizing the appearance and beautifying the kitchen environment.

[0011] 2) The reinforcing strip serves as a support point for the sink body, providing sufficient strength to prevent the diagonal strip from being stressed and thus avoid deformation at the connection between the diagonal strip and the diagonal edge of the countertop.

[0012] 3) Easy installation of fasteners, ensuring flexibility for undermount installation while providing sufficient locking strength.

[0013] Furthermore, the edge of the reinforcing strip is welded to the overhanging edge of the beveled strip, which, while ensuring support strength, simplifies and flexibly simplifies the production process, increases yield, and reduces production costs and difficulty. Alternatively, the reinforcing strip and the beveled strip are integrally formed, further strengthening the beveled strip and greatly extending the service life of the concealed sink.

[0014] Specifically, the four corners of the water tank body are provided with welded patches with a thickness of 1.05mm to connect the right-angled triangular structures on the four sides of the water tank body, so that the whole is smoothly transitioned.

[0015] Furthermore, the thickness of the reinforcing strip is 1-2 mm. Through repeated testing, the applicant determined that a sheet thickness of 1-2 mm provides the best support strength. If the sheet is too thick, it is difficult to bend; if it is too thin, the strength decreases. A sheet thickness of 1.35 mm provides the best bending and support strength.

[0016] Specifically, the beveled edge strip is integrally formed with the water tank body to avoid gaps between the beveled edge strip and the water tank body that could trap dirt and grime.

[0017] Furthermore, the bottom of the water tank body is provided with anti-collision foam to protect the stone platform and the water tank body from damage.

[0018] Another technical solution to the technical problem solved by this utility model provides an installation structure for a concealed sink, including a sink body, a reinforcing strip, a countertop, and a fastening assembly for fixing the sink body under the countertop. The sink body has a downwardly and outwardly inclined strip around its opening, corresponding to the inclined edge of the countertop. The reinforcing strip is an L-shaped right-angled strip placed below the inclined strip. The first right-angled surface of the reinforcing strip connects to the outer surface of the sink body, and one end connects to the suspended end of the inclined strip, forming a right-angled triangle structure around the opening of the sink body. The countertop is hollowed out to form an installation opening for embedding the sink body. An inclined edge is provided around the installation opening, and this inclined edge corresponds to and matches the inclined strip. The fastening assembly includes screws, pressure plates, and nuts. The screws are located under the countertop. The pressure plates pass through the screws and abut against the second right-angled surface of the reinforcing strip. The nuts are screwed into the screws to fix the pressure plates.

[0019] Compared with existing technologies, the concealed sink installation structure of this utility model has at least the following advantages:

[0020] 1) A right-angled triangular structure is formed on the outer periphery of the opening of the sink body by means of beveled strips and reinforcing strips. It matches and connects with the countertop with beveled edge, thereby hiding the thickness of the countertop, optimizing the appearance and beautifying the kitchen environment.

[0021] 2) The reinforcing strip serves as a support point for the sink body, providing sufficient strength to prevent the diagonal strip from being stressed and thus avoid deformation at the connection between the diagonal strip and the diagonal edge of the countertop.

[0022] 3) Easy installation of fasteners, ensuring flexibility for undermount installation while providing sufficient locking strength.

[0023] Specifically, the edge of the reinforcing strip is connected to the suspended edge of the beveled strip by welding.

[0024] Furthermore, the four corners of the water tank body are provided with welded patches with a thickness of 1.05mm to connect the right-angled triangular structures on the four sides of the water tank body.

[0025] Specifically, the bottom of the water tank body is provided with anti-collision foam, and / or the beveled strip is integrally formed with the water tank body, and / or the thickness of the reinforcing strip is 1-2mm. Attached Figure Description

The nut 38 is screwed onto the screw 36 to secure the pressure plate 37.

[0037] The countertop 40 for installing the concealed sink of this embodiment has a hollowed-out installation opening for embedding the sink body 10. The periphery of the installation opening is provided with a countertop bevel 42, which is matched and connected to the bevel strip 15.

[0038] The steps for installing the concealed sink of this embodiment under the countertop 40 are as follows: First, place the countertop 40 upside down on the installation workbench, with the bottom surface of the countertop 40 facing upwards. The opening of the sink body 10 should face downwards, corresponding to the installation opening of the countertop 40, and the beveled edge 42 of the countertop should be aligned and matched with the beveled strip 15. Then, place the pressure plate 37, pass the pressure plate 37 through the screw 36, and press it against the second right-angled surface 22 of the reinforcing strip 20. Next, install the nut 38, and screw the nut 38 and screw 36 together to fix the pressure plate 37, thereby fixing the sink body 10 to the bottom surface of the countertop 40. Finally, straighten the countertop 40, and the installation is complete.

[0039] Compared to existing technologies, the concealed sink and its installation structure in this embodiment optimize the appearance through beveled edge design while ensuring the flexibility of under-counter installation; fastening components and reinforcing strips enhance the stability of the sink body. The reinforcing strips, acting as load-bearing fulcrums, provide sufficient strength to ensure the beveled strips do not deform, thereby ensuring the service life of the sink body.

[0040] Furthermore, the bottom of the sink body is provided with anti-collision foam 50 to protect the stone platform and the sink body from damage.

[0041] The above embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model.
