Description

Drainage of urinal

In general, urinals are installed separately from the toilet in a public place or a toilet in the building to allow men to urinate, such urinals are composed of a rectangular pottery 10 with an anterior opening as shown in FIG. Vertically installed on the inner wall of the toilet, the upper center of the urinal is connected to the water faucet is composed of a water stool 20 for washing the urine by the user's choice, the washing water supplied through the water stool 20 urinal It is configured to be balanced in a horizontal row in the upper inner surface of the, the lower center of the urinal is composed of a drain 30 for discharging the washed urine to the septic tank.

In the urinal, the conventional drainage part 30 is provided with an upper housing 31 which is mounted on the upper surface of the pottery 10 through the lower center of the pottery 10 as shown in FIG. The upper housing 31 has a engaging piece 311 is formed on the upper outer periphery, the center is provided with a connecting tube 312 extending downward, the spiral 313 on the outer peripheral surface of the connecting tube 312 Is formed.

In addition, the lower housing 32 is provided to be screwed to the connecting pipe 312 spiral 313 of the upper housing 31. The lower housing 32 has a locking piece 321 formed on the upper outer periphery so as to be in close contact with the bottom surface of the pottery 10, and is screwed to the connecting pipe 312 of the upper housing 31 at the center thereof. Spiral 322 is formed on the inner circumferential surface, the drain pipe 323 is formed in the center extending a predetermined height to the top and extended to the bottom.

The upper packing 33 is interposed between the lower part of the upper housing 31 and the upper surface of the ceramic 10, and the upper packing 34 is interposed between the upper surface of the lower housing 32 and the bottom of the ceramic 10. Threaded coupling prevents leaks.

In addition, the upper housing 31 has a drain cap 35 having a plurality of drain grooves 351 through the openings, and having a odor blocking hole 352 integrally formed at a lower portion of the drain groove 351 to prevent the odor from flowing upward. It is seated on the upper portion of the connecting pipe (312).

The drainage device of the conventional urinal combined as described above has an advantage in FIG. 2 when the upper housing 31 and the lower housing 32 are separated and screwed together to be applied to a urinal having a large thickness of the pottery 10. As shown by the broken line, the lower housing 32 is spaced apart from the upper housing 31 and the spaced apart by the gap between the closed bottom surface of the lower housing 32 and the odor blocking port 352 so that the lower housing 32 ), There is a problem that the odor flows back through the drain pipe 323 because the water level of the residual water (W) is low, and also packed on the upper and lower surfaces of the pottery 10 when the upper and lower housings 31 and 32 are assembled. By interposing (33) (34), the assembling process is not only cumbersome, but also urine and washing water leaks out between the packing interposed in the lower part of the coarse pottery 10, which not only corrodes the urinal but also pollutes the environment around the urinal. Problem It is to solve this.

Hereinafter, the configuration of an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 is a side view of a general urinal, and FIG. 3 is an exploded perspective view of a drainage device to which the present invention is applied.

The urinal to which the present invention is applied consists of a rectangular pottery 10 having an open front and is installed vertically on the inner wall of the toilet, and the upper center of the urinal is connected to a water faucet to wash urine by the user's choice. (20) is configured, the washing water supplied through the water supply side 20 is configured to be sprayed in a horizontally balanced in the upper inner surface of the urinal, the lower center of the pottery 10 to drain the washed urine to the septic tank The part 40 is comprised.

The present invention in the drainage portion 40 of the urinal is a housing 41 which is seated on the upper portion of the pottery 10 and has a certain amount of residual water (W) in the lower portion, and the drainage is seated on the upper portion of the housing 41 Cap 43 and the fastening nut 42 which is fastened to the lower portion of the housing 41 to be coupled to the bottom surface of the pottery 10 is made, which will be described in more detail as follows.

The housing 41 forms a locking piece 411 which is caught on the upper surface of the pottery 10 on the upper outer circumference thereof, extends in a cylindrical shape having a predetermined diameter in the lower part of the center, and the spiral 413 is formed on the outer circumference of the lower part. Comprising the formed receiving tube 412, and through the lower center of the receiving tube 412 to a predetermined diameter it is provided with a drain pipe 414 extends a predetermined height to the top and extended to the bottom integrally or prefabricated.

In addition, the fastening nut 42 has a locking piece 421 formed at an upper outer circumference thereof, and a lower portion of the fastening nut 42 is formed through the diameter to accommodate the outer circumference of the housing 41, and a spiral 422 is formed at an inner circumferential surface thereof to extend a predetermined length. do.

In addition, the drain cap 43 seated on the upper portion of the housing 41 has a plurality of drain grooves 431 through the upper portion as usual, and downwardly opened at the lower portion thereof to prevent odors from entering the upper portion. Odor blocking block 432 is provided integrally.

Next will be described in detail the assembly process of the present invention configured as described above. First, the receiving tube 412 of the housing 41 is inserted into the through hole formed in the center of the ceramic 10 in the state where the packing 44 is inserted into the lower portion of the locking piece 411 of the housing 41, so that the upper surface of the ceramic 10 is closed. The locking piece 411 is seated so that the packing 44 is interposed therebetween. When the insertion of the housing 41 is completed in this way, the fastening cut 42 is inserted into the receiving tube 412 of the housing 41 drawn out to the lower portion of the pottery 10 and fastened to the spiral 413 formed on the outer peripheral surface of the lower end side thereof. By assembling the upper surface of the locking piece 421 completely to the bottom surface of the pottery 10 to complete the assembly of the housing 41, as described above when the assembly of the housing 41 is completed in the upper portion of the housing 41 Seat the drain cap (43). The drain cap 43 seated on the housing 41 is always maintained at a constant distance from the bottom surface of the receiving pipe 412 in which the residual water W is contained, regardless of the thickness change of the pottery 10.

The present invention integrates the housing, and when assembling, it is possible to assemble the pottery by fastening the fastening nut on the outer periphery of the lower end of the receiving tube through the packing only on the upper surface of the pottery, so that the urine washed out of the housing is urine Can be prevented from leaking to the outside. In particular, the bottom surface of the receiving pipe integrally formed in the housing containing the residual water and the bottom of the malodor blocking hole of the drain cap are always maintained at a constant distance regardless of the thickness of the lower portion of the ware to which the drainage device is coupled. The lower end of the odor blocking opening than the level of the residual water has the advantage of preventing the phenomenon of odor flow back through the drain.

The present invention is to provide a drainage device of the urinal that can accommodate the difference in the lower thickness of the urinal so that the odor blocking port of the drain cap can always be immersed in the replenishment water to prevent odor backflow.
