The present invention relates to a waterless urinal, in which a urine guide rod of a urine guide member is coupled to a discharge guide surface of a discharge guide member such that a discharge guide surface is quickly opened by urine moving to the urine guide member, thereby increasing a drainage velocity of urine, and thus sludge, scale, and a urinary calculus formed by the protein of urine are not generated, such that the function of the discharge guide surface may be maintained.

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 urinal100of the present invention, which is configured as described above, will be described as follows.

First, in a state in which the second installation guide body121of the second installation guide member120is coupled to the first installation guide body111of the first installation guide member110such that the outer circumferential thread122of the second installation guide body121engages with the inner circumferential thread113of the first installation guide body111, the second installation guide body121is rotated in one direction so as to allow the outer circumferential thread122to be fastened to the inner circumferential thread113.

When the outer circumferential thread122is fastened to the inner circumferential thread113, the upper end portion of the second installation guide body121is seated on the installation guide projection112of the first installation guide body111, such that the first installation guide body111is closed.

When the first installation guide member110to which the second installation guide member120is coupled is coupled to the installation hole11of the urinal10, an outer circumferential surface of the first installation guide member110is coupled to an inner circumferential surface of the installation hole11while coming into surface-to-surface contact with the inner circumferential surface of the installation hole11, and the first installation guide member110and the installation hole11are finished by a separate finishing member, such that urine is not drained between the first installation guide member110and the installation hole11.

In addition, when the urine drainage guide body131of the urine drainage guide member130is coupled to the second installation guide body121of the second installation guide member120, the urine drainage guide body131is completely coupled into the second installation guide body121while the upper end portion of the urine drainage guide body131is seated on the installation guide projection123of the second installation guide body121, and the discharge guide body141of the discharge guide member140, which is made of a silicone material, is coupled to the urine drainage guide body131of the urine drainage guide member130.

In this case, the discharge guide surface143formed at the lower end portion of the discharge guide body141is completely coupled into the urine drainage guide body131while the catching piece142formed at the upper end portion of the discharge guide body141is seated on the catching projection132of the urine drainage guide body131, and the urine guide body151of the urine guide member150is coupled to the discharge guide body141of the discharge guide member140.

The urine guide rod155, which is provided at the lower end portion of the urine guide body151and has the guide groove156formed therein, is coupled to the guide rod coupling groove144while passing through the interior of the discharge guide body141, such that the urine guide rod155comes into contact with an inner surface of the guide rod coupling groove144, and at the same time, a bottom surface of the urine guide body151comes into close contact with the upper end portion of the discharge guide body141, that is, the catching piece142, and in this case, as illustrated inFIG. 5, the coupling projection162, which protrudes on the attaching and detaching body161of the attaching and detaching member160, is coupled to the urine drainage hole153, and thereafter, the knob163of the attaching and detaching member160is rotated in one direction.

As the knob163is rotated in one direction, the attaching and detaching body161, the coupling projection162, and the urine guide body151having the urine drainage hole153to which the coupling projection162is coupled, are rotated in one direction, and at the same time, the installation guide projection152, which is formed in a streamlined shape on the outer circumferential surface of the urine guide body151, is fastened and coupled to the installation guide groove124that is formed in a streamlined shape in the inner circumferential surface of the second installation guide body121of the second installation guide member120, such that the urine guide body151of the urine guide member150presses the catching piece142of the discharge guide member140, and the catching piece142is compressed and deformed between the urine guide body151and the catching projection132of the urine drainage guide member130so as to tightly close the urine guide body151and the catching projection132, and as a result, the installation of the waterless urinal100is completed as illustrated inFIG. 6.

As illustrated inFIGS. 7 to 8, when a user urinates into the waterless urinal100of the present invention, which is completely installed as described above, the urine from the user flows downward along an inner surface of the urinal10and moves to an upper surface of the urine guide body151, and because the upper surface of the urine guide body151is 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 body151, is drained to the urine drainage hole153.

In this case, the urine is drained to the urine drainage hole153by the urine guide projection154that protrudes at a center of the urine guide body151.

The urine drained to the urine drainage hole153moves between the urine guide rod155and the guide rod coupling groove144along an inclined inner surface of the discharge guide body141, and at the same time, quickly flows downward along the guide groove156, which is recessed in a streamlined shape in the outer circumferential surface of the urine guide rod155, so as to presses the lower end portion of the guide rod coupling groove144and the discharge guide surface143, and the discharge guide surface143is spread and opened by the urine flowing downward along the guide groove156, such that the urine may be quickly drained along the opened discharge guide surface143.

The urine drained to the discharge guide surface143is drained to a septic tank along a pipe installed to the installation hole11of the urinal10, and when the urine is completely drained and no urine flows downward to the urine guide member150along the inner surface of the urinal10, the discharge guide surface143, which has been spread by the movement of urine, is restored by its own elasticity, and portions of the discharge guide surface143come into surface-to-surface contact with each other so as to close the discharge guide body141, such that the urinal10waits for the next operation.

In addition, in a case in which it is necessary to replace the discharge guide member140after the aforementioned processes are repeatedly performed, the urine guide member150may be separated from the second installation guide member120using the attaching and detaching member160, and thereafter the discharge guide member140may be separated from the urine drainage guide member130and replaced, and a new discharge guide member may be seated on the urine drainage guide member130, and thereafter, the urine guide member150is mounted in the second installation guide member120, and as a result, the urinal may be used.
