The invention provides a hand washing table.

As shown in fig. 1 to 4, in the embodiment of the present invention, the hand washing station includes a substrate 10 and a ceramic basin blank 20, a through hole 11 is formed in a middle portion of a top surface of the substrate 10, an edge portion of the ceramic basin blank 20 is installed in the through hole 11, an adhesive space 30 is formed by the edge portion of the ceramic basin blank 20 and a wall of the through hole 11, and a sealing gap 31 is formed in a front surface of the substrate 10 by the adhesive space 30; the sealing gap 31 is covered with a glaze layer (not shown).

According to the technical scheme, the base plate 10 and the ceramic basin body 20 are seamlessly spliced, and then the surface of the sealing gap 31 formed by the adhesive space 30 on the front surface of the base plate 10 is subjected to glazing process treatment, so that the sealing gap 31 is completely covered by a glaze layer (not shown), the appearance quality of a product is improved, the problem that bacteria and mildew are bred in the adhesive space due to the bonding gap is thoroughly solved, sanitary dead corners are eliminated, and the product is easy to clean and manage. In addition, because the inclined plane of the ceramic basin blank body 20 is processed before glazing, the surface is not easy to damage and easy to process, thereby improving the qualification rate of seamless splicing of the washbasin and reducing the production cost.

It should be understood that the pot blank 20 refers to a fired glazed pot, and that the glaze layer (not shown) covering the sealing gap 31 and the glaze layer of the pot blank 20 are produced simultaneously.

Alternatively, the glaze layer (not shown) includes a center glaze layer covering the inner surface of the ceramic pot blank 20 and an edge glaze layer surrounding the center glaze layer, and the edge glaze layer is disposed around the sealing gap 31 in the surrounding direction and covers the sealing gap 31. That is, the inner side surface of the ceramic pot blank 20 and the surface of the sealing gap 31 are covered with a layer of glaze. By applying the edge glaze layer on the surface of the sealing gap 31 and applying the central glaze layer on the inner side surface of the ceramic basin blank 20, the color of the front appearance of the wash basin is unified, the color difference between the ceramic basin blank 20 and the sealing gap 31 is avoided, and the attractiveness of the wash basin is improved.

The glaze is used as a vitreous layer on the surface of the ceramic, and has the advantages of durability, easy washing and cleaning, and acid, alkali and salt corrosion resistance due to small water absorption, stable chemical property and high glaze hardness. The ceramic glaze has various types, and can be divided into lime glaze, feldspar glaze and the like according to the components of the glaze; according to the firing temperature, the glaze can be divided into high-temperature glaze and low-temperature glaze; according to the appearance characteristics after firing, the glaze can be divided into transparent glaze, opaque glaze, colored glaze, glazed glaze, matt glaze, crystalline glaze, glass glaze, flaked glaze, transmutation glaze and the like. There are also many glazing methods, such as dipping, pouring, spraying, swinging, brushing, etc.

In this embodiment, in order to make the substrate 10 unglazed, the substrate 10 is covered with newspaper or a film, and then the ceramic pot blank 20 is subjected to a glaze spraying process to form a glaze layer.

The glaze spraying process is one of the ceramic ware making process and is the process of applying glaze slurry to the surface of the formed ceramic body. At present, the glaze spraying process of ceramics is divided into two types, namely manual glaze spraying and mechanical automatic glaze spraying, for example, a full-automatic ceramic glaze spraying machine is a device for spraying a glaze layer on the surface of a ceramic product, a rotary platform for placing the ceramic product and an automatic material spraying device are arranged in the machine, and glaze is uniformly sprayed on the surface of the ceramic product by the automatic material spraying device in the rotation process of the ceramic product along with the rotary platform, so that the glaze spraying process is completed.

Further, a reinforcing structure 30 is fixed to the back surface of the base plate 10, and the reinforcing structure 30 is mounted on the outer side surface of the ceramic pot blank 20. By arranging the reinforcing structure 30, the fixing strength of the substrate 10 and the ceramic basin blank 20 is improved, and the purpose of secondarily reinforcing the joint of the edge of the ceramic basin blank 20 and the hole wall of the through hole 11 is achieved.

Further, a groove 31 is formed in one side of the reinforcing structure 30 close to the gluing space 30, and a side surface of an edge portion of the ceramic basin blank 20 is located in the groove 31 and attached to a side wall of the groove 31. The groove 31 is attached to the edge of the ceramic basin blank 20 in a complementary manner, so that the fixing strength of the substrate 10 and the ceramic basin blank 20 is improved.

Specifically, the groove 31 includes a vertical face and an inclined face. When the reinforcing structure 30 is fixedly sleeved from bottom to top, the vertical surface is attached to the side surface of the second sealing gap 32, and the inclined surface is attached to the side surface of the edge of the ceramic basin blank 20, so that a clamping complementary structure is formed.

Furthermore, the outer side of the end face of the edge of the ceramic basin blank 20 is exposed outside the through hole 11, and forms an overflow space 22 with the bottom surface of the substrate 10. The glue overflow space 22 is used for accommodating excess bonding glue, and when bonding, a small amount of bonding glue overflow can be left in the glue overflow space 22 and cannot overflow from the edge of the ceramic pot blank 20.

Further, the groove 31 is bonded to the side surface of the edge portion of the ceramic basin blank 20 by a glue layer. The bonding installation is simple swift, improves the installation effectiveness. In this embodiment, the bonding glue is a rock plate bonding glue, and the rock plate bonding glue has the characteristics of low temperature resistance, high temperature resistance, yellowing resistance, strong adaptability to the environment, and the like. In other embodiments, other adhesive glues may be used, and are not limited herein.

Optionally, the hole wall of the through hole 11 is formed with a first inclined surface 12, the end surface of the edge of the ceramic basin blank 20 is formed with a second inclined surface 21, and an adhesive space 30 is formed between the first inclined surface 12 and the second inclined surface 21. The mode of oblique cutting and gluing is adopted, so that the bonding seam is small, the cleaning and sanitation are easy, the use by people is convenient, the environment protection, the safety, the sanitation and the beauty are realized, the defects and the hidden troubles of the traditional hand basin are overcome, and the body health of people is facilitated.

Further, the first inclined surface 12 is inclined upward and gathered near the center of the through hole 11, and the second inclined surface 21 is inclined upward and gathered 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 are inclined upward. Through the first inclined plane 12 and the second inclined plane 21, the hand washing basin 20 is convenient to assemble and install from bottom to top, and the installation convenience is improved.

Specifically, the distance between one end of the first inclined surface 12 close to the through hole 11 and one end of the second inclined surface 21 close to the through hole 11 is close to zero, and the distance between one end of the first inclined surface 12 far away from the through hole 11 and the other end of the second inclined surface 21 far away from the through hole 11 gradually increases, that is, the space generated by the first inclined surface 12 and the second inclined surface 21 is annular and radial. Therefore, the interface between the substrate 10 and the ceramic basin blank 20 is smooth, the sealing gap on the front surface of the washbasin is as small as possible, the problem that mold bacteria are bred in the sealing gap is avoided as much as possible, and the attractiveness of the covered glaze layer is improved.

In other embodiments, the first inclined surface 12 and the second inclined surface 21 may be parallel, but at the same time, the joint is also ensured to be tight and flat, if the joint is uneven, the height difference between the base plate 10 and the hand washing basin 20 is caused, and the joint is larger.

In this embodiment, the glue added to the glue space 30 is also a rock plate glue. The rock plate adhesive has the characteristics of low temperature resistance, high temperature resistance, yellowing resistance, strong environmental adaptability and the like. In other embodiments, other adhesive glues may be used, and are not limited herein.
