Description

Technical Field

[0001] The present invention relates to the field of sanitary wares, and particularly to a urinal and its manufacturing process. Background Art

[0002] At present, the sewage discharge pipes of existing urinals can be classified into the following two types according to the material: one is a plastic pipe, which is bonded to the bottom of the urinal body; the other is a ceramic pipe, which is integrally formed with the urinal body. For the plastic sewage discharge pipe, after long-term use, it is prone to deformation due to the impact of water flow and the influence of gravity, and the material oxidizes, and gaps or even detachment are likely to occur at the bonding part. For the ceramic sewage discharge pipe, since it is integrally formed with the urinal body, there are too many small parts in the mold, it is difficult to demold the blank, and the risk of pipe deformation is high. Summary of the Invention

[0003] In view of the technical problems existing in the prior art, the present invention provides a urinal and its manufacturing process, in which the sewage discharge pipe is firmly bonded and easy to form.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a urinal, including a urinal body and a sewage discharge pipe, and the sewage discharge pipe is provided with a water seal bend; both the sewage discharge pipe and the urinal body are made of ceramic material, and the sewage discharge pipe and the urinal body are independently formed respectively, and are bonded and fixed in the wet blank state.

[0005] Further, reinforcing rib plates are arranged on the outside of the sewage discharge pipe between both sides of the water seal bend, and the water seal bend is in a U shape.

[0006] Further, the sewage inlet of the sewage discharge pipe is sleeved outside the urine discharging part of the urinal body, and a positioning flange is arranged in the sewage inlet of the sewage discharge pipe, and the positioning flange abuts against the bottom surface of the urine discharging part of the urinal body and bears the bonding paste between the sewage inlet of the sewage discharge pipe and the urine discharging part of the urinal body.

[0007] Further, the sewage inlet of the sewage discharge pipe is in a flared shape with a wider upper part and a narrower lower part.

[0008] Further, the sewage discharge pipe is a rear-discharge type, a positioning step is arranged on the outer side surface of the upper wall body at the rear of the sewage discharge pipe, and the positioning step fits with the lower edge at the rear of the urinal body; the lower wall body at the rear of the sewage discharge pipe is in a slope shape with a higher front part and a lower rear part.

[0009] Further, the inner wall of the sewage discharge pipe is glazed to form a glaze layer.

[0010] The present invention further provides a manufacturing process of a urinal, including the following steps:

[0011] 1) Blanking: The urinal body blank and the sewage discharge pipe blank are respectively made of ceramic materials. The sewage discharge pipe blank is provided with a water seal bend.

[0012] 2) Bond and fix the urinal body blank and the sewage discharge pipe blank in the wet blank state with an adhesive paste.

[0013] 3) Fire and process the bonded urinal body blank and sewage discharge pipe blank together.

[0014] Furthermore, the sewage inlet and the sewage outlet of the sewage discharge pipe blank respectively form the grouting hole and the slurry discharging hole of the production mold of the sewage discharge pipe blank.

[0015] Furthermore, reinforcing rib plates are arranged between the two sides of the water seal bend on the outside of the sewage discharge pipe blank. The water seal bend is U-shaped. The inner wall of the sewage discharge pipe blank is glazed to form a glaze layer.

[0016] Furthermore, during bonding, the sewage inlet of the sewage discharge pipe blank is sleeved outside the urine discharging part of the urinal body blank, and a ring of positioning flange arranged in the sewage inlet of the sewage discharge pipe blank abuts against the bottom surface of the urine discharging part of the urinal body blank and bears the adhesive paste between the sewage inlet of the sewage discharge pipe blank and the urine discharging part of the urinal body. The sewage inlet of the sewage discharge pipe blank is in the shape of a trumpet with a wider upper part and a narrower lower part. The sewage discharge pipe is of a rear-discharge type. A positioning step is arranged on the outer side of the upper wall body at the rear of the sewage discharge pipe blank, and the positioning step fits with the lower edge at the rear of the urinal body. The lower wall body at the rear of the sewage discharge pipe is in the shape of a slope with a higher front part and a lower rear part.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Since both the sewage discharge pipe and the urinal body are made of ceramic materials, and the sewage discharge pipe and the urinal body are independently formed and bonded and fixed in the wet blank state, the present invention not only realizes an overall ceramic material, making the sewage discharge pipe antioxidant, corrosion-resistant and non-deformable, but also makes the connection part between the sewage discharge pipe and the urinal body very firm and stable, and at the same time solves the problems such as numerous small parts in the mold and difficult blank removal existing in the integral molding of the sewage discharge pipe and the urinal body.

[0019] 2. The reinforcing rib plates can play a supporting role, preventing the wet blank of the sewage discharge pipe from sagging and deforming under the action of gravity during the drying process, thereby reducing the deformation rate of the sewage discharge pipe after firing.

[0020] 3. The setting of the positioning flange not only improves the positioning accuracy between the sewage discharge pipe and the urinal body, but also can prevent the adhesive paste from flowing into the sewage discharge pipe, thereby avoiding the adhesive paste from affecting the flatness of the inner wall of the sewage discharge pipe and the inner diameter of the pipe.

[0021] 4. The sewage inlet of the sewage pipe is in the shape of a trumpet with a wider upper part and a narrower lower part, which is conducive to the adhesion of the bonding paste and facilitates the implementation of bonding.

[0022] 5. The setting of the positioning step can ensure that the height of the sewage outlet of the sewage pipe meets the standard.

[0023] 6. The lower wall of the rear part of the sewage pipe is in the shape of a slope with a higher front and a lower rear, which can accelerate the sewage discharge speed and reduce the residue in the pipe.

[0024] 7. The inner wall of the sewage pipe is glazed to form a glaze layer, making the inner wall of the sewage pipe smooth and not easy to scale after firing.

[0025] 8. The sewage inlet and the sewage outlet of the sewage pipe blank respectively constitute the grouting hole and the slurry discharging hole of the production mold of the sewage pipe blank. The present invention can not only effectively utilize the discharging air flow to flatten the inner wall of the pipe, ensure the smoothness of the inner wall of the sewage pipe blank, but also eliminate the need for plugging the slurry discharging hole operation, effectively avoiding process defects such as defective blanks, pipe burrs, pipe air leakage, pipe deformation, and cracking at the plugging position caused by the plugging operation.

The reinforcing rib plate 22 can play a supporting role to prevent the wet blank of the sewage pipe 2 from collapsing and deforming under the action of gravity during the drying process, thereby reducing the deformation rate of the sewage pipe 2 after firing.

[0032] In this embodiment, the sewage inlet 23 of the sewage discharge pipe 2 is sleeved outside the urine discharging part 11 of the urinal body 1, and a positioning flange 231 is provided in the sewage inlet 23 of the sewage discharge pipe 2.
