Description

Technical Field

[0001] This invention relates to the field of bathroom technology, and in particular to a washbasin and its preparation method. Background Technology

[0002] As society develops and people's living standards continue to improve, their awareness of hygiene is also increasing, and their requirements for handwashing stations are also getting higher and higher.

[0003] Existing washbasins typically use a base plate as the countertop and a ceramic basin as the undermount, connected by adhesive or fasteners. In a consistently humid environment, this seam easily traps dirt and grime, fostering bacteria and mold growth, posing hygiene risks and impacting health. Over time, the surface darkens and becomes difficult to clean, affecting the overall appearance and user experience. Furthermore, when the ceramic basin and base plate are joined at an angle, the basin rim needs to be beveled. Ceramic basins are highly susceptible to cracking and breakage during cutting, resulting in a scrap rate of 10-30%, directly increasing production costs.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] The main objective of this invention is to provide a washbasin and a method for seamless splicing thereof, which aims to solve the problems that the joint between the slab and the ceramic under-counter basin is prone to accumulating dirt and grime, affecting the product's appearance, and that the ceramic basin is prone to cracking and breakage when cut, leading to increased production costs.

[0006] To achieve the above objectives, the present invention provides a handwashing station comprising:

[0007] A substrate, wherein a through hole is formed in the center of the top surface of the substrate; and

[0008] A ceramic basin blank, the edge of which is installed in the through hole, the edge of which forms an adhesive space with the wall of the through hole, and the adhesive space forms a sealing gap on the front side of the substrate.

[0009] The sealing gap is covered with a glaze layer.

[0010] Optionally, the glaze layer includes a central glaze layer and an edge glaze layer surrounding the central glaze layer. The central glaze layer covers the inner surface of the ceramic basin body, and the edge glaze layer is arranged around the sealing gap in the surrounding direction and covers the sealing gap.

[0011] Optionally, a reinforcing structure is fixed to the back of the substrate, and the reinforcing structure is installed on the outer surface of the ceramic pot blank.

[0012] Optionally, the reinforcing structure has a groove on the side near the adhesive space, and the side of the edge of the ceramic basin blank is located in the groove and is fitted to the side wall of the groove.

[0013] Optionally, the outer side of the edge of the ceramic basin blank is exposed outside the through hole, forming an overflow space with the bottom surface of the substrate.

[0014] Optionally, the groove is bonded to the side of the edge of the ceramic basin body by an adhesive layer.

[0015] Optionally, the wall of the through hole is formed with a first inclined surface, and the end face of the edge of the ceramic basin blank is formed with a second inclined surface, and the adhesive space is formed between the first inclined surface and the second inclined surface.

[0016] Optionally, the first inclined surface is inclined upward and converges near the center of the through hole, and the second inclined surface is inclined upward and converges near the center of the through hole.

[0017] This invention also proposes a method for preparing a handwashing basin, comprising the following steps:

[0018] Making the ceramic basin blank;

[0019] A through hole is made on the top surface of the substrate according to the dimensions of the ceramic blank;

[0020] The edge of the ceramic basin blank is installed into the through hole, and the adhesive space formed by the edge of the ceramic basin blank and the hole wall of the through hole is filled with adhesive.

[0021] Glazing is applied to the sealing gap formed on the front side of the substrate and the inner surface of the ceramic basin so that the glaze layer covers the sealing gap.

[0022] The handwashing basin is obtained by sintering.

[0023] Optionally, before the step of installing the edge of the ceramic basin blank into the through hole, the method further includes:

[0024] Cut a bevel on the edge of the ceramic basin blank to match the bevel of the inner wall of the through hole; or...

[0025] A ceramic basin blank is produced by molding process, wherein the edge has a slope that matches the slope of the inner wall of the through hole.

[0026] This invention's technical solution involves seamlessly splicing a substrate and a ceramic basin body, then applying a glazing process to the surface of the sealing gap formed by the adhesive space on the front of the substrate. This completely covers the sealing gap with glaze, improving the product's appearance quality and effectively solving the problem of bacteria and mold growth in the adhesive space caused by the bonding gap, eliminating hygiene dead spots and making the product easy to clean. Furthermore, since the beveled surface of the ceramic basin body is treated before glazing, the surface is less prone to damage and easier to process, thereby increasing the success rate of seamless splicing of the washbasin and reducing production costs.

[0038] This invention proposes a handwashing station.

[0039] like Figures 1 to 4 As shown, in this embodiment of the invention, the washbasin includes a base plate 10 and a ceramic basin blank 20. A through hole 11 is formed in the middle of the top surface of the base plate 10. The edge of the ceramic basin blank 20 is installed in the through hole 11. The edge of the ceramic basin blank 20 and the hole wall of the through hole 11 form an adhesive space 30. A sealing gap 31 is formed on the front side of the base plate 10 in the adhesive space 30. The sealing gap 31 is covered with a glaze layer (not shown).

[0040] The technical solution of this invention involves seamlessly splicing the substrate 10 and the ceramic basin body 20, and then applying a glazing process to the surface of the sealing gap 31 formed by the adhesive space 30 on the front side of the substrate 10. This completely covers the sealing gap 31 with a glaze layer (not shown), improving the product's appearance quality and thoroughly solving the problem of bacteria and mold growth in the adhesive space caused by the bonding gap, eliminating hygiene dead spots and making the product easy to clean. Furthermore, since the beveled surface of the ceramic basin body 20 is treated before glazing, the surface is less prone to damage and easier to process, thereby improving the pass rate of seamless splicing of the washbasin and reducing production costs.

[0041] It should be understood that the ceramic basin body 20 refers to the glazed and fired ceramic basin, and the glaze layer (not shown) covering the sealing gap 31 and the glaze layer of the ceramic basin body 20 are formed at the same time.

[0042] Optionally, the glaze layer (not shown) includes a central glaze layer and an edge glaze layer surrounding the central glaze layer. The central glaze layer covers the inner surface of the ceramic basin body 20, and the edge glaze layer is arranged around the sealing gap 31 in the circumferential direction and covers the sealing gap 31. That is, a layer of glaze is applied to both the inner surface of the ceramic basin body 20 and the surface of the sealing gap 31. By applying an edge glaze layer to the surface of the sealing gap 31 and a central glaze layer to the inner surface of the ceramic basin body 20, the color of the front appearance of the washbasin is unified, avoiding color difference between the ceramic basin body 20 and the sealing gap 31, thereby improving the aesthetics of the washbasin.

[0043] Glaze, as a vitreous layer on the surface of ceramics, possesses low water absorption, stable chemical properties, and high surface hardness, making porcelain durable, easy to wash and maintain cleanliness, and resistant to acid, alkali, and salt corrosion. There are many types of ceramic glazes. According to their composition, they can be divided into lime glazes, feldspar glazes, etc.; according to firing temperature, they can be divided into high-temperature glazes and low-temperature glazes; and according to their appearance after firing, they can be divided into transparent glazes, opaque glazes, colored glazes, glossy glazes, matte glazes, crystalline glazes, glassy glazes, crackled glazes, kiln-transformed glazes, etc. There are also various glazing methods, such as dipping, pouring, spraying, scouring, and brushing.

[0044] In this embodiment, in order to prevent the substrate 10 from being glazed, the substrate 10 is first covered with newspaper or film, and then the ceramic basin body 20 is subjected to a glazing process to generate a glaze layer.

[0045] Glazing is a ceramic manufacturing process that involves applying glaze to the surface of a shaped ceramic body. Currently, ceramic glazing processes are divided into manual glazing and automated mechanical glazing. For example, a fully automatic ceramic glazing machine is used to spray a glaze layer onto the surface of ceramic products. The machine has a rotating platform for placing the ceramic products and an automatic spraying device. As the platform rotates, the automatic spraying device evenly sprays glaze onto the surface of the ceramic products, completing the glazing process.

[0046] Furthermore, a reinforcing structure 30 is fixed to the back of the substrate 10, and the reinforcing structure 30 is installed on the outer surface of the ceramic basin blank 20. By setting the reinforcing structure 30, the fixing strength between the substrate 10 and the ceramic basin blank 20 is improved, thereby achieving the purpose of secondary reinforcement of the connection between the edge of the ceramic basin blank 20 and the hole wall of the through hole 11.

[0047] Furthermore, the reinforcing structure 30 has a groove 31 on the side near the adhesive space 30, and the side of the edge of the ceramic basin blank 20 is located in the groove 31 and is fitted to the side wall of the groove 31. The groove 31 and the edge of the ceramic basin blank 20 are fitted together to improve the fixing strength between the substrate 10 and the ceramic basin blank 20.

[0048] Specifically, the groove 31 includes a vertical surface and an inclined surface. When the reinforcing structure 30 is fitted and fixed from bottom to top, the vertical surface fits against the side of the second sealing gap 32, and the inclined surface fits against the side of the ceramic basin body 20, forming a complementary interlocking structure.

[0049] Furthermore, the outer side of the edge of the ceramic basin body 20 is exposed outside the through hole 11, forming an overflow space 22 with the bottom surface of the substrate 10. The overflow space 22 is used to accommodate excess adhesive. If a small amount of adhesive overflows during bonding, it will remain in the overflow space 22 and will not overflow from the edge of the ceramic basin body 20.

[0050] Furthermore, the groove 31 is bonded to the side of the ceramic basin body 20 via an adhesive layer. This bonding installation is simple and quick, improving installation efficiency. In this embodiment, a sintered stone adhesive is used, which has characteristics such as low-temperature resistance, high-temperature resistance, yellowing resistance, and strong environmental adaptability. In other embodiments, other adhesives may be used, and this is not a limitation.

[0051] Optionally, the wall of the through hole 11 is formed with a first bevel 12, and the end face of the edge of the ceramic basin body 20 is formed with a second bevel 21. An adhesive space 30 is formed between the first bevel 12 and the second bevel 21. This beveled adhesive method results in smaller joints, making cleaning easier and more convenient for use. It is also more environmentally friendly, safer, more hygienic, and more aesthetically pleasing, solving the defects and potential hazards of traditional washbasins and benefiting people's health.

[0052] Furthermore, the first inclined surface 12 and the second inclined surface 21 are both inclined upwards and converge near the center of the through hole 11. That is, the first inclined surface 12 and the second inclined surface 21 are inclined in the same direction and both converge upwards. The first inclined surface 12 and the second inclined surface 21 facilitate the installation of the washbasin 20 from bottom to top, improving the ease of installation.

[0053] Specifically, the distance between the end of the first inclined surface 12 near the through hole 11 and the end of the second inclined surface 21 near the through hole 11 is almost zero, while the distance between the end of the first inclined surface 12 away from the through hole 11 and the other end of the second inclined surface 21 away from the through hole 11 gradually increases, meaning the space created by the first inclined surface 12 and the second inclined surface 21 is annular and radial. This ensures a smooth interface between the substrate 10 and the ceramic basin body 20, minimizing the sealing gaps on the front of the washbasin and thus minimizing the growth of mold and bacteria in the sealing gaps. It also improves the aesthetics after the glaze is applied.

[0054] In other embodiments, the first inclined surface 12 and the second inclined surface 21 can also be parallel, but at the same time, it is also necessary to ensure that the interface is clean and flat. If the splicing is not flat, then there will be a height difference between the substrate 10 and the washbasin 20, resulting in a relatively large seam.

[0055] In this embodiment, the adhesive added to the adhesive space 30 is also a slab adhesive. Slab adhesive has characteristics such as low-temperature resistance, high-temperature resistance, yellowing resistance, and strong environmental adaptability. In other embodiments, other adhesives may be used, and there are no limitations here.

[0056] This invention also proposes a method for preparing a handwashing basin, comprising the following steps:

[0057] Making the ceramic basin blank;

[0058] Through holes are made on the top surface of the substrate according to the size of the ceramic blank;

[0059] The edge of the ceramic basin blank is installed into the through hole, and the adhesive space formed by the edge of the ceramic basin blank and the hole wall is filled with adhesive.

[0060] Glazing is applied to the sealing gap formed on the front side of the substrate and the inner surface of the ceramic basin to cover the sealing gap with glaze.

[0061] Sintering yields a handwashing basin.

[0062] By bonding the substrate and the ceramic basin body together, and then glazing the sealed gaps and the inner surface of the ceramic basin body, the gaps are completely covered by the glaze, improving the product's appearance quality. This also completely eliminates the problem of bacteria and mold growth in the adhesive space caused by the bonding gaps, eliminating hygiene dead spots and making the product easy to clean. Furthermore, because the sloping surface of the ceramic basin is treated before glazing, the surface is less prone to damage and easier to process, thereby increasing the success rate of seamless splicing of the washbasin and reducing production costs.

[0063] In this embodiment, the substrate is a sintered stone slab. The sintering temperatures of sintered stone slabs and ceramics are similar, with the average firing temperature of ceramics being between 1100℃ and 1300℃. After glazing, the entire washbasin can be placed directly into the kiln for sintering at a temperature of 1100-1300℃ to form a complete glaze surface.

[0064] Sintered stone slabs are a new type of ultra-large-format ceramic material made from natural raw materials through a special process, pressed using presses with a capacity of over 10,000 tons (over 15,000 tons), combined with advanced production technology, and fired at temperatures above 1200℃. They can withstand cutting, drilling, and polishing. Sintered stone slabs are composed of 100% natural components from three groups of elements: minerals derived from granite—quartz and feldspar—providing strength and solidity; minerals derived from glass and quartz, providing stability; and natural oxides, giving them unique colors. The main manufacturing processes for sintered stone slabs are sintering and 3D technology. Sintering refers to recreating the natural formation process of natural stone over millions of years within tens of hours. Raw materials are pressed under 400 tons of high pressure and then fired in a roller kiln at temperatures above 1400℃. Combined with 3D technology, this creates layered textures with subtle variations in light and shadow, and clear patterns. Sintered stone slabs possess excellent properties such as ultra-thinness, ultra-lightweight, ultra-large size, ultra-scratch resistance, ultra-corrosion resistance, and ultra-environmental friendliness.

[0065] Optionally, before the step of installing the edge of the ceramic basin body into the through hole, the method further includes:

[0066] Cut a bevel along the edge of the ceramic basin blank to match the bevel of the inner wall of the through hole; or...

[0067] A ceramic basin blank is produced by molding, with the edge having a slope that matches the slope of the inner wall of the through hole.

[0068] At this stage, the ceramic basin blank is a shaped but unsintered green body. During this phase, the blank is cut and trimmed to create beveled edges for easier assembly. Alternatively, a mold with beveled edges can be made first, and the ceramic basin blank can be formed through pressure casting. Both methods are simple and easy to process, facilitating seamless assembly of the ceramic basin blank and the substrate. This avoids the problem of ceramic basins easily cracking and breaking during cutting, improves the success rate of seamless assembly, and reduces production costs.

[0069] Optionally, the step of opening a through hole on the top surface of the substrate according to the size of the ceramic blank further includes: milling a beveled surface into the inner wall of the through hole of the substrate.

[0070] By using the beveled inner wall of the through-hole in the substrate and the beveled edge of the ceramic basin body, the substrate and the ceramic basin body can be beveled at a certain angle, which facilitates seamless splicing and achieves a visually seamless effect. In this embodiment, the bevel angle of the inner wall of the through-hole in the substrate is 40-50°, and the bevel angle of the edge of the ceramic basin body is 45°, so that an adhesive space for filling the adhesive is formed between the substrate and the ceramic basin body. The size of this adhesive space varies depending on the type of adhesive, ensuring that the adhesive has sufficient space to accommodate bonding. If the space is too large, the bonding strength will be reduced; if the space is too small, adhesive will easily overflow, affecting the seamless splicing effect.

[0071] Optionally, after the step of filling and bonding the adhesive space formed by the edge of the ceramic basin body and the wall of the through hole, the method further includes:

[0072] After 24–48 hours, once the adhesive has fully cured, the washbasin should be surface treated.

[0073] After filling the gap between the ceramic pot body and the substrate with a special sealant of similar color, the gap is then ground and polished using professional tools and techniques, such as using a sponge, angle grinder, sandpaper, etc. to remove excess adhesive.

[0074] Optionally, after the sintering process to obtain the washbasin, the following steps are included:

[0075] After the washbasin has cooled down, a fixing block for reinforcement is installed on the back of the base plate. The fixing block is bonded to the ceramic basin body with adhesive.

[0076] In this embodiment, as Figure 2 As shown, a reinforcing structure 40 is provided on the back of the substrate 10, and the reinforcing structure 40 is connected to the edge of the ceramic basin blank 20. A groove 31 is provided on the side of the reinforcing structure 30 near the adhesive space 30. The side of the edge of the ceramic basin blank 20 is located within the groove 31 and is adhered to the side wall of the groove 31 by an adhesive layer. The reinforcing structure 40 improves the fixing strength between the substrate 10 and the ceramic basin blank 20, increasing the bonding strength and stability to prevent detachment and cracking.
