Description

Technical Field

[0001] This utility model relates to the field of bathroom products technology, and in particular to a urinal. Background Technology

[0002] Currently, the sewage pipes of existing bottom-enclosed urinals are all single-sided suction molding structures. For sewage pipes with single-sided suction molding, the internal cavity volume is large and holds a lot of water, resulting in low sewage replacement capacity, easy accumulation of urine stains, odor, and easy blockage of the sewage pipe after long-term use.

[0003] Chinese patent CN111993547A discloses a urinal in which the drain pipe and the urinal body are formed independently and bonded together in a wet state. However, this structure has the following problems: (1) The drain pipe is a single curved pipe with a U-shaped water trap. This drain pipe structure can only be formed by single-sided suction molding. The pipe formed by single-sided suction molding is affected by suction time, temperature environment, etc., making it difficult to accurately control the inner diameter of the pipe. Moreover, flow marks caused by slurry discharge will appear on the inner wall of the pipe, making it not smooth enough; (2) There are two bonding positions between the drain pipe and the urinal body. Do not place the sewage inlet and outlet near the sewage outlet, as the bonding is difficult and the risk of misalignment is high. When the blank is fired at high temperature in the kiln, the shrinkage force direction is different, which can easily lead to deformation and cracking. (3) This sewage pipe structure can only be inserted into the urinal body from bottom to top for bonding, which means that only the bottom open design can be made, which limits the appearance design of the urinal and cannot be made into a shape with the bottom fully enclosed. If the bottom is to be fully enclosed, a large space must be reserved inside the urinal body for the sewage pipe to enter from the back. In this case, not only is the appearance size design of the urinal limited, but it is also inconvenient to observe the bonding position. Utility Model Content

[0004] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. Therefore, the present invention proposes a urinal.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] The urinal according to an embodiment of the present utility model includes:

[0007] The urinal body is made of ceramic and has an inner liner, a waste inlet, a waste inlet section, and a connecting rib. The waste inlet is located at the bottom of the inner liner, and the waste inlet section is located below the waste inlet. The inner liner, waste inlet, and waste inlet section are connected in sequence. A waste outlet is provided at the lower end of the waste inlet section. The inner liner, waste inlet, and waste inlet section constitute the main body of the urinal body. The connecting rib is located on the rear side of the main body and extends laterally from the main body to form a first waste outlet semi-cavity with an open rearward opening. The waste outlet is connected to the first waste outlet semi-cavity and is close to the bottom of the first waste outlet semi-cavity.

[0008] The splice body is made of ceramic and has a second drainage half-cavity and a drainage outlet. The opening of the second drainage half-cavity faces forward, and the periphery of the opening of the first drainage half-cavity matches the periphery of the opening of the second drainage half-cavity and is connected by adhesive grout. The first drainage half-cavity and the second drainage half-cavity form a drainage channel. The drainage outlet is located at the rear end of the second drainage half-cavity and is higher than the drainage hole. The drainage channel and the sewage inlet section form a U-shaped water trap. The splice body is formed by double-sided grout suction process.

[0009] The urinal according to the embodiment of this utility model has at least the following beneficial effects:

[0010] 1. The urinal body and the splicing body of this utility model are independently formed. The water trap is disassembled into a sewage channel and a sewage inlet section, which are formed separately. The sewage channel is further disassembled into two half-cavities, one in front and one in back, which are formed separately, similar to being cut along the axis of the sewage channel. This allows the splicing body, which is the rear half of the sewage channel, to be formed by double-sided suction molding. The double-sided suction molding of the splicing body makes its thickness controllable and unaffected by factors such as suction time and temperature environment. The inner wall of the second sewage half-cavity is smooth. The inner side of the sewage inlet section of the urinal body is formed by single-sided suction molding, while the outer wall of the rear side of the main body of the urinal body (i.e., the outer wall of the rear wall of the inner liner and the sewage inlet section) and the connecting rib are formed by the forming surface of the mold. This makes the inner wall of the first sewage half-cavity also smooth. Since the sewage channel is composed of the first sewage half-cavity and the second sewage half-cavity, the inner diameter of the sewage channel can be precisely controlled.

[0011] 2. The urinal body and the splicing body are glued together by their open openings, with only one glued point. The glued part is the perimeter of the open opening, which is a closed ring shape. During firing, the stress is evenly distributed, making it less prone to deformation or cracking.

[0012] 3. The splicing body is inserted into the urinal body from the back and glued to the back of the main body of the urinal. It can be glued without leaving much space, which provides more possibilities for the appearance design of the urinal and can be made into a structure that is fully enclosed at the bottom.

[0013] According to some embodiments of the present invention, the drain hole is located at the lower end of the rear wall of the inlet section.

[0014] According to some embodiments of the present invention, the second sewage discharge semi-cavity is generally inverted L-shaped, which is surrounded by a horizontal wall and a vertical wall. The sewage outlet is located on the rear side of the horizontal wall, and the vertical wall is located below the front side of the horizontal wall. The horizontal wall and the vertical wall are smoothly connected. The opening of the second sewage discharge semi-cavity extends from the bottom end of the vertical wall to the top end of the horizontal wall.

[0015] According to some embodiments of the present invention, the splicing body is further provided with reinforcing ribs, which are located on the outer side of the second sewage discharge half-cavity and are connected between the lower end of the transverse wall and the rear end of the vertical wall.

[0016] According to some embodiments of the present invention, a first positioning step is formed around the opening periphery of the first sewage discharge half-cavity, and a second positioning step is formed around the opening periphery of the second sewage discharge half-cavity, wherein the first positioning step and the second positioning step are adapted to each other.

[0017] According to some embodiments of the present invention, the urinal body further comprises a support frame for supporting the main body. The main body and the support frame are integrally formed. The support frame has an upper sealing portion and a lower sealing portion. The upper sealing portion is located above the main body, and the lower sealing portion is located below the main body. The rear ends of the upper sealing portion and the rear ends of the lower sealing portion are located in the same vertical direction.

[0018] According to some embodiments of the present invention, the support frame further has a left sealing portion and a right sealing portion, the left sealing portion and the right sealing portion are respectively located on the left and right sides of the main body, and the rear ends of the left sealing portion and the right sealing portion are located in the same vertical direction as the rear end of the lower sealing portion.

[0030] Reference Figure 1-6 A urinal, comprising:

[0031] The urinal body 100 is made of ceramic and comprises an inner liner 110, a waste inlet 120, a waste inlet section 130, and a connecting rib 140. The waste inlet 120 is located at the bottom of the inner liner 110, and the waste inlet section 130 is located below the waste inlet 120. The inner liner 110, waste inlet 120, and waste inlet section 130 are connected in sequence. A drain hole 131 is provided at the lower end of the waste inlet section 130. The sludge section 130 constitutes the main body of the urinal body 100. The connecting rib 140 is located on the rear side of the main body. The connecting rib 140 extends laterally from the main body to form a first sewage discharge half cavity 150 with an open rearward opening. That is, the first sewage discharge half cavity 150 is formed by the rear wall of the inner liner 110, the rear wall of the sludge inlet section 130 and the connecting rib 140. The sewage discharge hole 131 is connected to the first sewage discharge half cavity 150 and is close to the bottom of the first sewage discharge half cavity 150.

[0032] The splice body 200 is made of ceramic. The splice body 200 forms a second drainage half-cavity 210 and a drainage outlet 220. The opening of the second drainage half-cavity 210 faces forward. The periphery of the opening of the first drainage half-cavity 150 matches the periphery of the opening of the second drainage half-cavity 210 and is connected by adhesive grout. The first drainage half-cavity 150 and the second drainage half-cavity 210 form a drainage channel 300. The drainage outlet 220 is located at the rear end of the second drainage half-cavity 210 and is higher than the drainage hole 131. The drainage channel 300 and the sewage inlet section 130 form a U-shaped water trap. The splice body 200 is formed by double-sided suction grouting process.

[0033] In some embodiments of this utility model, the drain hole 131 is opened at the lower end of the rear wall of the sewage inlet section 130.

[0034] In some embodiments of this invention, the second drainage semi-cavity 210 is generally inverted L-shaped, formed by a transverse wall 230 and a vertical wall 240. The drainage outlet 220 is located behind the transverse wall 230, and the vertical wall 240 is located below the front of the transverse wall 230. The transverse wall 230 and the vertical wall 240 are smoothly connected. The opening of the second drainage semi-cavity 210 extends from the bottom of the vertical wall 240 to the top of the transverse wall 230. The inverted L-shaped structure of the second drainage semi-cavity 210 can control the inner diameter of the drainage channel 300, reduce the volume of the drainage channel 300, improve the sewage replacement function of the urinal, and avoid odor or blockage problems caused by urine stains.

[0035] In some embodiments of this utility model, the splice body 200 is further provided with reinforcing ribs 250. The reinforcing ribs 250 are located on the outer side of the second drainage half-cavity 210 and are connected between the lower end of the transverse wall 230 and the rear end of the vertical wall 240. Providing reinforcing ribs 250 at the corner of the transverse wall 230 and the vertical wall 240 can provide support, prevent the wet blank of the splice body 200 from deforming during the drying process, and reduce the firing deformation rate of the product.

[0036] In some embodiments of this utility model, a first positioning step 141 is formed around the opening periphery of the first sewage discharge semi-cavity 150, and a second positioning step 211 is formed around the opening periphery of the second sewage discharge semi-cavity 210. The first positioning step 141 and the second positioning step 211 are adapted to each other. During bonding, adhesive is applied to the first positioning step 141, and the second positioning step 211 is then attached to the first positioning step 141. The positioning steps not only improve the positioning accuracy of the spliced ​​body 200 and the urinal body 100, but also improve the bonding quality, making the bonded part very firm and stable.

[0037] In some embodiments of this utility model, the urinal body 100 further includes a support frame 160 for supporting the main body. The main body and the support frame 160 are integrally formed. The support frame 160 has an upper sealing portion 161 and a lower sealing portion 162. The upper sealing portion 161 is located above the main body, and the lower sealing portion 162 is located below the main body. The rear ends of the upper sealing portion 161 and the lower sealing portion 162 are located in the same vertical direction. Further, the support frame 160 also has a left sealing portion and a right sealing portion. The left and right sealing portions are located on the left and right sides of the main body, respectively. The rear ends of the left and right sealing portions are located in the same vertical direction as the rear end of the lower sealing portion 162. The upper sealing portion 161, the lower sealing portion 162, the left sealing portion, and the right sealing portion form a fully enclosed structure for the support frame 160, resulting in a simple and elegant appearance.

[0038] The urinal of this utility model is manufactured according to the following steps:

[0039] S1: The blanks of the urinal body 100 and the splicing body 200 are made by using ceramic slurry. The blank of the splicing body 200 is formed by double-sided slurry suction process.

[0040] S2: The blank of the urinal body 100 and the blank of the splicing body 200 are bonded and fixed in the wet blank state using adhesive paste to obtain the combined blank;

[0041] S3: The assembled blanks are dried, glazed, and fired in sequence to obtain the urinal. Glazing makes the inner wall of the U-shaped water trap smooth after firing, making it less prone to scaling.

[0042] In step S1, the double-sided slurry suction process is as follows: the mold core 400 and the mold cavity 500 are closed to form a molding cavity; ceramic slurry is injected into the molding cavity to obtain the blank of the assembled body 200. The inner wall of the second drainage half-cavity 210 is formed by the mold core 400. Figure 5 As shown.

[0043] Step S1 also includes using a punch to drill a drain hole 131 on the blank of the urinal body 100. The sewage inlet section 130 of the urinal body 100 is formed by single-sided suction molding. After molding, the rear wall of the sewage inlet section 130 is closed, so a drain hole 131 needs to be drilled on the rear wall of the sewage inlet section 130.

[0044] Step S1 also includes using a punch to create a drain outlet 220 on the blank of the splice body 200. After double-sided suction molding, the rear end of the splice body 200 is a closed wall. Creating a drain outlet 220 on this wall provides better strength for the blank compared to directly forming the drain outlet 220 using a mold, and also makes it easier to demold.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
