Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to a bathroom cabinet enamel basin. Background Technology
[0002] Bathroom vanities typically come with a washbasin. Traditional washbasins are made of ceramic, making them heavy and causing significant problems with hanging and installing the vanity. Their thickness also occupies a large amount of internal space, resulting in limited storage space. Furthermore, the drain outlets on existing panels are often located in the middle, further reducing storage space at the bottom of the basin and compromising the vanity's storage functionality. Therefore, this invention provides an enamel washbasin specifically designed for bathroom vanities, which solves the aforementioned technical problems. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model proposes a lightweight and thin enamel basin structure.
[0004] A bathroom vanity enamel basin includes a basin body, a drain assembly, and an overflow collector.
[0005] The thickness of the main body of the basin is 1.5mm-3mm. The frame is made of metal sheet extrusion and covered with an enamel coating on the outer periphery. The overall thickness is thin and the weight is light.
[0006] The main body of the washbasin includes a sink, side supports, and a front support. To reduce space waste, the sink adopts a rear-mounted layout: there are two side supports, respectively located on both sides of the sink opening, and the front support is located at the end of the sink closer to the user. The side supports and the front support form a U-shaped support on the front of the sink, and the bottom surface of the U-shaped support and the outer perimeter of the sink form a U-shaped drawer installation space. Thus, a compact U-shaped drawer can be installed under the washbasin in the bathroom cabinet, improving the storage capacity of the bathroom cabinet.
[0007] The sink is equipped with a water outlet, which is designed to be located at the rear, closer to the side of the sink away from the user. This avoids the problem of the water outlet affecting the storage space at the bottom of the basin if it is centrally located.
[0008] The side of the water tank away from the user has an overflow hole to prevent water from overflowing.
[0009] The drainer is installed at the outlet of the water tank, and the overflow collector is installed on the outer periphery of the water tank and covers the overflow hole.
[0010] The washbasin provided by this utility model is constructed with a metal frame and an enamel coating. Compared with traditional ceramic washbasins, it has the advantages of being lightweight and thin, thereby improving the stability of the bathroom cabinet's hanging installation and reducing the space occupied inside the cabinet. The washbasin provided by this utility model also features a U-shaped drawer installation space around the perimeter of the sink, allowing a compact U-shaped drawer to be installed under the washbasin, increasing the cabinet's storage capacity. Furthermore, placing the drain outlet at the rear of the sink also reduces the impact of the drain assembly on the cabinet's storage space.
[0011] Preferably, to prevent water from splashing onto the wall when using water, the bathroom vanity enamel basin also includes a baffle, which is located at the top of the basin body away from the user.
[0012] Preferably, to improve the overall integrity, the baffle and the basin body frame are integrated or welded together and covered with enamel, thereby eliminating the gap between the baffle and the basin body, preventing dirt and grime from accumulating. In addition, there is no need to apply silicone sealant between the basin body and the wall, which avoids the problem of silicone sealant becoming moldy and black after long-term use, and improves the cleanliness of the bathroom cabinet.
[0013] Preferably, the width of the side support plate is 135mm-155mm, and the width of the front support plate is 105mm-125mm.
[0014] Preferably, a protruding post is welded to the outer periphery of the overflow hole of the water tank. The protruding post has a screw hole, and the overflow collector is installed on the outside of the water tank by screws, ensuring a firm installation and good sealing. Alternatively, a protruding post with a screw hole is welded to one side of the outer periphery of the overflow hole, and a Z-shaped piece is welded to the other side. One side of the overflow collector is inserted into the gap between the Z-shaped piece and the basin body, and the other side is installed on the protruding post by screws.
[0015] Preferably, to improve the sealing performance of the overflow collector and prevent dripping, the outer ring of the overflow collector's inlet is provided with an annular groove, and a sealing ring is embedded in the annular groove.
[0016] Preferably, the overflow hole is horizontally elongated, which not only has a good drainage effect, but also takes advantage of the fact that the enamel basin will not deform to form a flat overflow hole.
[0017] Preferably, the side support plate has an arc-shaped concave center, which connects to a water tank, allowing water that drips or spills onto the support plate to drain into the water tank and prevent water accumulation on the support plate.
[0018] Preferably, the periphery of the basin body is rolled downwards, which on the one hand can prevent the periphery of the basin body from cracking easily, and on the other hand can prevent the user from being cut.
[0019] Preferably, the inner side of the curl is provided with a rubber pad, which can improve the installation stability and sealing of the basin body, and also avoid rigid impact on the basin body during installation.
[0020] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:
[0021] The washbasin provided by this utility model is composed of a metal frame and an enamel covering layer. Compared with traditional ceramic washbasins, it has the advantages of being lightweight and thin, thereby improving the stability of the bathroom cabinet's hanging installation and reducing the space occupied inside the bathroom cabinet.
[0022] The washbasin provided by this utility model has a U-shaped drawer installation space set around the perimeter of the sink, which allows the bathroom cabinet to install a compact U-shaped drawer at the bottom of the washbasin, thereby improving the storage capacity of the bathroom cabinet. In addition, placing the water outlet of the sink at the rear also reduces the impact of the drain on the storage space of the bathroom cabinet.
[0023] The bathroom vanity enamel basin also includes a baffle to prevent water from splashing onto the wall when using water.
[0024] The baffle and the main body of the basin are integrated or welded together and covered with enamel, thereby eliminating the gap between the baffle and the main body of the basin, preventing dirt and grime from accumulating. In addition, there is no need to apply silicone sealant between the main body of the basin and the wall, which avoids the problem of silicone sealant becoming moldy and black after long-term use, and improves the cleanliness of the bathroom cabinet.
[0025] A protruding post is welded to the outer periphery of the overflow hole, which makes it possible to install the overflow collector.
[0026] The perimeter of the basin body is curled downwards, which on the one hand prevents the perimeter of the basin body from cracking easily, and on the other hand prevents the user from being cut. Attached Figure Description

Detailed Implementation
[0038] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0039] Please see Figures 1 to 7 A bathroom vanity enamel basin includes a basin body 1, a drain 2, and an overflow collector 3.
[0040] The thickness of the main body 1 of the basin is 1.5mm-3mm. The frame part is formed by extruding metal plate and covered with an enamel coating on the outer periphery. The overall thickness is thin and the weight is light.
[0041] In one embodiment, the periphery of the basin body 1 is rolled downwards. This prevents the periphery of the basin body 1 from cracking easily and also avoids cutting the user. Preferably, a rubber pad is provided on the inner side of the rolled-up area, which can improve the installation stability and sealing of the basin body 1 and also prevent the basin body 1 from being subjected to rigid impact during installation.
[0042] The basin body 1 includes a water tank 11, a side support plate 12, and a front support plate 13. Preferably, the width of the side support plate 12 is 135mm-155mm, and the width of the front support plate 13 is 105mm-125mm. For example, in this embodiment, preferably, the width of the side support plate 12 is 145mm, and the width of the front support plate 13 is 115mm. Additionally, preferably, the side support plate 12 has an arc-shaped concave portion in the middle, which connects to the water tank 11, allowing water dripping or spilling onto the support plate to drain into the water tank 11, preventing water accumulation on the support plate.
[0043] To reduce space waste, the sink 11 adopts a rear-mounted layout structure: there are two side support plates 12, which are respectively set on both sides of the sink 11 opening, and the front support plate 13 is set at the end of the sink 11 closer to the user. The side support plates 12 and the front support plate 13 form a U-shaped support plate on the front of the sink 11, and the bottom surface of the U-shaped support plate and the outer periphery of the sink 11 form a U-shaped drawer installation space 14. Thus, a compact U-shaped drawer 5 can be installed under the sink in the bathroom cabinet, improving the storage capacity of the bathroom cabinet.
[0044] The sink 11 is provided with a water outlet 111. The water outlet 111 adopts a rear-mounted design, which is close to the side of the sink 11 away from the user. This avoids the problem of affecting the storage space at the bottom of the basin when the water outlet 111 is set in the center.
[0045] The side of the sink 11 away from the user has an overflow hole 112 to prevent water from overflowing. In one embodiment, the overflow hole 112 is horizontally elongated, which not only has a good drainage effect, but also takes advantage of the fact that the enamel basin will not deform to form a flat overflow hole 112.
[0046] The drain assembly 2 is installed at the outlet 111 of the water tank 11, and the overflow collector 3 is installed on the outer periphery of the water tank 11, covering the overflow hole 112. In one embodiment, a protruding post 15 is welded to the outer periphery of the overflow hole 112 on the outer periphery of the water tank 11. The protruding post 15 is provided with screw holes, and the overflow collector 3 is installed on the outside of the water tank 11 by screws, which is secure and has good sealing performance. Of course, in other embodiments, it can also be glued on. Alternatively, please refer to [link to relevant documentation]. Figure 8 In other embodiments, a protruding post 15 with a screw hole is welded to one side of the outer periphery of the overflow hole 112, and a Z-shaped piece is welded to the other side. The overflow collector 3 is inserted into the gap between the Z-shaped piece and the basin body 1 on one side, and is mounted on the protruding post 15 on the other side by screws. In addition, the Z-shaped piece can be set on the upper side, lower side, left side or right side of the overflow hole 112.
[0047] In addition, to improve the sealing performance of the overflow collector 3 and prevent dripping, an annular groove is provided on the outer ring of the water inlet of the overflow collector 3, and a sealing ring is embedded in the annular groove.
[0048] In one embodiment, to prevent water from splashing onto the wall when using water, the bathroom cabinet enamel basin also includes a baffle 4, which is located at the top of the basin body 1 away from the user.
[0049] Based on the above embodiments, in order to improve the integrity, the baffle 4 and the frame of the basin body 1 are integrated or welded together and covered together with enamel, thereby eliminating the gap between the baffle 4 and the basin body 1, preventing dirt and grime from accumulating. In addition, there is no need to apply silicone sealant between the basin body 1 and the wall, which can avoid the problem of silicone sealant becoming moldy and black after long-term use, and improve the cleanliness of the bathroom cabinet.
[0050] The washbasin provided by this utility model is constructed with a metal frame and an enamel coating. Compared with traditional ceramic washbasins, it has the advantages of being lightweight and thin, thereby improving the stability of the bathroom cabinet's hanging installation and reducing the space occupied inside the bathroom cabinet. The washbasin provided by this utility model, by setting a U-shaped drawer installation space 14 around the perimeter of the sink 11, allows the bathroom cabinet to install a compact U-shaped drawer 5 at the bottom of the washbasin, improving the storage capacity of the bathroom cabinet. In addition, placing the water outlet 111 of the sink 11 at the rear also reduces the impact of the drain 2 on the storage space of the bathroom cabinet.
