## Background
CROSS-REFERENCE TO PRIOR APPLICATIONS
This application is a national Stage Patent Application of PCT International Patent Application No. PCT/KR2013/001967, filed on Mar. 12, 2013 under 35 U.S.C. §371, which claims priority of Korean Patent Application No. 10-2012-0025501, filed on Mar. 13, 2012, which are all hereby incorporated by reference in their entirety.
TECHNICAL FIELD
The present invention relates to a waterless urinal, and more particularly, to a waterless urinal, in which urine moving to a urine guide member moves to a guide rod coupling groove of a discharge guide member through a urine guide rod, and at the same time, a discharge guide surface is quickly opened by the moving urine, thereby increasing a drainage velocity of urine, to prevent sludge, scale, and a urinary calculus formed by the protein of urine from being generated, such that the function of the discharge guide surface may be maintained.
BACKGROUND ART
Because public health regulations state that an offensive odor or gas generated from drain pipes should be sealed and isolated, the urinal installed on a wall in a toilet needs to discharge urine and water through the drain pipe when a user urinates, and prevent a reverse flow of an offensive odor by residual water remaining at an upper end portion of the drain pipe.
However, the aforementioned urinal has problems in that because a large amount of water is used when the user flushes the urinal, water resources are exhausted and maintenance costs are increased, and an offensive odor is generated by urine remaining in residual water.
In order to solve the aforementioned problems, a fluid control valve has been recently published in Korean Patent Application Laid-Open No. 10-2005-084278.
The aforementioned published patent application has a configuration that provides a constituent element having a flat strip made of a flexible elastic material which terminates at a lower end portion in a support trough-shaped section, and a surface at which an end portion of the strip may be sealed, and may solve the problems in the related art by allowing a fluid to flow only in one direction, but there is a problem in that in a case in which the strip is not restored due to insufficient elasticity, a flow velocity of urine is low, which causes the occurrence of an offensive odor, and a reverse flow of an offensive odor cannot be blocked.
In addition, there is a problem in that an opening and closing function of the strip is lost due to sludge, scale, and a urinary calculus which are generated from the protein of urine that is drained onto the strip and adsorbed onto a surface of the strip, and as a result, it is difficult to block a reverse flow of the offensive odor.

Installation and operational processes of the waterless urinal 100 of the present invention, which is configured as described above, will be described as follows.
First, in a state in which the second installation guide body 121 of the second installation guide member 120 is coupled to the first installation guide body 111 of the first installation guide member 110 such that the outer circumferential thread 122 of the second installation guide body 121 engages with the inner circumferential thread 113 of the first installation guide body 111, the second installation guide body 121 is rotated in one direction so as to allow the outer circumferential thread 122 to be fastened to the inner circumferential thread 113.
When the outer circumferential thread 122 is fastened to the inner circumferential thread 113, the upper end portion of the second installation guide body 121 is seated on the installation guide projection 112 of the first installation guide body 111, such that the first installation guide body 111 is closed.
When the first installation guide member 110 to which the second installation guide member 120 is coupled is coupled to the installation hole 11 of the urinal 10, an outer circumferential surface of the first installation guide member 110 is coupled to an inner circumferential surface of the installation hole 11 while coming into surface-to-surface contact with the inner circumferential surface of the installation hole 11, and the first installation guide member 110 and the installation hole 11 are finished by a separate finishing member, such that urine is not drained between the first installation guide member 110 and the installation hole 11.
In addition, when the urine drainage guide body 131 of the urine drainage guide member 130 is coupled to the second installation guide body 121 of the second installation guide member 120, the urine drainage guide body 131 is completely coupled into the second installation guide body 121 while the upper end portion of the urine drainage guide body 131 is seated on the installation guide projection 123 of the second installation guide body 121, and the discharge guide body 141 of the discharge guide member 140, which is made of a silicone material, is coupled to the urine drainage guide body 131 of the urine drainage guide member 130.
In this case, the discharge guide surface 143 formed at the lower end portion of the discharge guide body 141 is completely coupled into the urine drainage guide body 131 while the catching piece 142 formed at the upper end portion of the discharge guide body 141 is seated on the catching projection 132 of the urine drainage guide body 131, and the urine guide body 151 of the urine guide member 150 is coupled to the discharge guide body 141 of the discharge guide member 140.
The urine guide rod 155, which is provided at the lower end portion of the urine guide body 151 and has the guide groove 156 formed therein, is coupled to the guide rod coupling groove 144 while passing through the interior of the discharge guide body 141, such that the urine guide rod 155 comes into contact with an inner surface of the guide rod coupling groove 144, and at the same time, a bottom surface of the urine guide body 151 comes into close contact with the upper end portion of the discharge guide body 141, that is, the catching piece 142, and in this case, as illustrated in FIG. 5, the coupling projection 162, which protrudes on the attaching and detaching body 161 of the attaching and detaching member 160, is coupled to the urine drainage hole 153, and thereafter, the knob 163 of the attaching and detaching member 160 is rotated in one direction.
As the knob 163 is rotated in one direction, the attaching and detaching body 161, the coupling projection 162, and the urine guide body 151 having the urine drainage hole 153 to which the coupling projection 162 is coupled, are rotated in one direction, and at the same time, the installation guide projection 152, which is formed in a streamlined shape on the outer circumferential surface of the urine guide body 151, is fastened and coupled to the installation guide groove 124 that is formed in a streamlined shape in the inner circumferential surface of the second installation guide body 121 of the second installation guide member 120, such that the urine guide body 151 of the urine guide member 150 presses the catching piece 142 of the discharge guide member 140, and the catching piece 142 is compressed and deformed between the urine guide body 151 and the catching projection 132 of the urine drainage guide member 130 so as to tightly close the urine guide body 151 and the catching projection 132, and as a result, the installation of the waterless urinal 100 is completed as illustrated in FIG. 6.
As illustrated in FIGS. 7 to 8, when a user urinates into the waterless urinal 100 of the present invention, which is completely installed as described above, the urine from the user flows downward along an inner surface of the urinal 10 and moves to an upper surface of the urine guide body 151, and because the upper surface of the urine guide body 151 is formed to be curved downward, the urine is smoothly moved, and the urine, which has been moved to the upper surface of the urine guide body 151, is drained to the urine drainage hole 153.
In this case, the urine is drained to the urine drainage hole 153 by the urine guide projection 154 that protrudes at a center of the urine guide body 151.
The urine drained to the urine drainage hole 153 moves between the urine guide rod 155 and the guide rod coupling groove 144 along an inclined inner surface of the discharge guide body 141, and at the same time, quickly flows downward along the guide groove 156, which is recessed in a streamlined shape in the outer circumferential surface of the urine guide rod 155, so as to presses the lower end portion of the guide rod coupling groove 144 and the discharge guide surface 143, and the discharge guide surface 143 is spread and opened by the urine flowing downward along the guide groove 156, such that the urine may be quickly drained along the opened discharge guide surface 143.
The urine drained to the discharge guide surface 143 is drained to a septic tank along a pipe installed to the installation hole 11 of the urinal 10, and when the urine is completely drained and no urine flows downward to the urine guide member 150 along the inner surface of the urinal 10, the discharge guide surface 143, which has been spread by the movement of urine, is restored by its own elasticity, and portions of the discharge guide surface 143 come into surface-to-surface contact with each other so as to close the discharge guide body 141, such that the urinal 10 waits for the next operation.
In addition, in a case in which it is necessary to replace the discharge guide member 140 after the aforementioned processes are repeatedly performed, the urine guide member 150 may be separated from the second installation guide member 120 using the attaching and detaching member 160, and thereafter the discharge guide member 140 may be separated from the urine drainage guide member 130 and replaced, and a new discharge guide member may be seated on the urine drainage guide member 130, and thereafter, the urine guide member 150 is mounted in the second installation guide member 120, and as a result, the urinal may be used.
While the present invention has been described above with reference to the limited exemplary embodiments and drawings, terms or words used in the present specification and the claims should not be interpreted as a general and dictionary meaning and should be interpreted as a meaning and a concept which conform to the technical spirit of the present invention. Accordingly, since the exemplary embodiments disclosed in the present specification and the configurations illustrated in the drawings are just the exemplary embodiments of the present invention and do not fully represent the technical spirit of the present invention, it should be appreciated that various equivalents and modified examples may be made without departing from the scope of the claims of the present invention.
