Description

{BAD SMELL INTERCEPTION WATERLESS URINAL}

The present invention relates to a waterless urinal, and more particularly, to a malodor-free water-containing urinal which can prevent odors from flowing backward.

According to the sanitary regulations, it is stipulated that the odor or gas generated in the drain pipe should be sealed or sealed. Therefore, the urinal installed on the wall of the toilet must discharge the urine and water together with the water when the toilet is used, and prevent the backflow of the odor by the remaining water at the upper end of the water pipe.

However, the conventional urinal has a disadvantage that water resources are exhausted and maintenance cost increases because a large amount of water is used when water is discharged.

Recently, a waterless urinal has been developed which can minimize the use of water. A waterless urinal has been disclosed in Patent No. 10-0897534 entitled " Odor Block Trap of a Free Water Urine ". Although a waterless urinal has an advantage of minimizing the use of water, there is a problem that the odor flows backward from the urine outlet pipe connected to the toilet.

Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

FIG. 1 is a perspective view showing the construction of a waterless urinal 100 according to the present invention, and FIG. 2 is a sectional view showing a sectional configuration of a waterless urinal 100.

As shown in the figure, the ahydrous urinal 100 according to the present invention includes a urinal main body 110 for urinating by a user, a malodor shield trap 120 disposed at a lower portion of the urinal main body 110, And a urine drainage pipe 140 connected to the lower portion and discharging the urine to the outside.

The urinal body 110 is installed perpendicular to the wall surface. A water supply pipe 130 is connected to the upper portion of the urinal body 110. The water supply pipe 130 is used to supply water for cleaning the urinal body 110.

The urine drainage pipe 140 is connected to the lower portion of the urinal body 110 as shown in Fig. The urine drain pipe 140 is connected to the urine outlet 111 of the urinal body 110 to discharge the urine W into an external purification tank or the like.

The malodor shield trap 120 is inserted into the urine discharge tube 140 through the urine outlet 111 and discharged. The malodor shield trap 120 prevents the odor moving on the urine discharge pipe 140 from flowing back to the urinal main body 110.

FIG. 3 is an exploded perspective view showing an external configuration of the malodor shield trap 120, FIG. 4 is an exploded perspective view of the malodor shield trap 120, Fig.

As shown in the drawing, the malodor shield trap 120 is inserted into the upper end of the urine drainage pipe 140 through the urine outlet 111. The malodor shield trap 120 includes a trap main body 121 to be inserted into the urine discharge pipe 140, a discharge cap 123 to cover the upper portion of the trap main body 121, A film seizing ring 127 disposed between the malodor shield film 125 and the trap main body 121 to support the malodor shield film 125, And a urine discharge tray 129 disposed at a predetermined distance from the lower portion of the urine discharge tray 129.

The trap main body 121 is inserted into the urine outlet 111. The trap main body 121 includes a support ring 121a supported on the outer circumferential surface of the urine outlet 111 and an insertion tube 121b extending to the lower portion of the support ring 121a and inserted into the urine outlet tube 140 for a predetermined length . The support ring 121a is formed to have a predetermined area and is contactably supported by the lower portion of the urinal body 110 surrounding the urine outlet 111. [ The support ring 121a is held in contact with the urinal main body 110 so that the malodor shield trap 120 can be fixed in the urine discharge tube 140. [

The insertion tube 121b is formed by extending a certain length to the lower portion of the support ring 121a. The insertion tube 121b is formed to have an outer diameter corresponding to the diameter of the urine outlet 111. A first thread 121c is formed in an upper region of the inner wall surface of the insertion tube 121b.

A ring receiving surface 121d is formed in a lower portion of the first screw thread 121c so as to protrude radially inwardly along the inner wall surface by a predetermined area. A film seating ring 127 is seated on the ring seating surface 121d and fixed in position.

The discharge cap 123 covers the upper portion of the insertion tube 121b opened by the support ring 121a. The urine outlet 111 is also covered by the discharge cap 123 covering the upper portion of the insertion tube 121b. The discharge cap 123 includes a cap main body 123a formed with a urine discharge hole 123b through the plate surface, a second screw thread 123c formed on the outer peripheral surface of the cap main body 123a, An engaging shaft 123d formed on the upper surface of the cap body 123a and engaged with the urine discharging tray 129 and a urine guiding protrusion 123f protruding from the upper surface of the cap body 123a.

The cap body 123a is formed in the shape of a circular plate having a certain area. At this time, a second screw thread 123c is formed along the side surface of the cap main body 123a. The second threaded portion 123c is threadedly engaged with the first threaded portion 121c so that the discharge cap 123 is maintained in a fixed state with the trap body 121. [ The first screw thread 121c and the second screw thread 123c may be formed of a female screw and a male screw.

Here, the upper surface of the cap body 123a is formed so that the middle region thereof is inclined so as to be lower in height than the outer circumference. Thus, the urine flows along the plate surface of the cap body 123a and can be easily discharged to the urine discharge hole 123b. The urine guiding projections 123f protrude from the central region of the cap body 123a so that the urine does not collect in the central region but moves to the urine discharging hole 123b. The urine guiding projection 123f may be formed in a hemispherical protruding shape.

The engaging shaft 123d extends from the cap body 123a by a predetermined length and is engaged with the urine discharging dish 129. A third thread 123e is formed on the lower part of the coupling shaft 123d so that the shaft coupling pipe 129a is screwed to the fourth thread 129b.

The film seating ring 127 is disposed between the trap body 121 and the malodor shielding film part 125 to support the malodor shielding film part 125. The film seating ring 127 is provided with a seating ring main body 127a supported by the ring seating surface 121d of the trap main body 121 and a lower portion of the seating ring main body 127a, And a film guide tube 127c for guiding the film guide 127c.

The seat ring body 127a is formed in a circular ring shape. The seat ring main body 127a is seated on the ring seating surface 121d as shown in Fig. 5 and the cap coupling end 127d extending upward is in contact with the lower portion of the discharge cap 123. Fig.

The film guide tube 127c is positioned inside of the inner wall surface of the insertion tube 121b to be in contact with the outer surface of the film tube 125b. Since the film guide tube 127c is made of a hard material, the outer surface of the film tube 125b of soft material is contacted and supported so that the film tube 125b is vertically arranged in a state of being wrinkled and tight.

The malodor shield film part 125 is seated on the film seating ring 127 to guide the urine to be discharged to the urine discharging dish 129. The malodor shielding film part 125 includes an upper ring 125a that is seated on the film seating ring 127, a film tube 125b that extends downward from the upper ring 125a, And a lower ring 125c disposed at the periphery.

The upper ring 125a is seated on the film seating surface 127b and fixed in position. The upper ring 125a is formed of a hard material and is stably fixed on the film seating surface 127b.

The film tube 125b is formed by bonding a flexible film to the upper ring 125a in the form of a cylinder. The film tube 125b is formed to extend downward from the upper ring 125a so that the lower end thereof is submerged in the urine (W) accumulated in the urine discharging dish 129.

The lower ring 125c is coupled to the outer surface of the lower end of the film tube 125b to apply weight to the film tube 125b so that the film tube 125b maintains a cylindrical shape. The film tube 125b maintains the shape of the circular tube so that the urine can be smoothly discharged to the urine discharging dish 129.

Further, the state in which the lower end of the film tube 125b is immersed in the urine of the urine discharging dish 129 can be maintained by the support of the lower ring 125c.

The urine discharge tray 129 is coupled to the lower portion of the engagement shaft 123d to discharge urine into the urine discharge tube 140. [ The urine discharge tray 129 is formed to be larger in diameter than the insertion tube 121b. The urine discharge tray 129 is formed in a concave shape as a center area. Whereby the depth of the center region is formed deeper than the depth of the outer periphery.

In the middle region of the urine discharge tray 129, an axial coupling pipe 129a coupled with the coupling shaft 123d is protruded. The fourth screw thread 129b is formed on the inner wall surface of the shaft coupling pipe 129a and is screwed to the third screw thread 123e.

The urine moved downward along the film tube 125b falls onto the upper surface of the urine discharging dish 129. At this time, it is preferable that the lower end of the film tube 125b is arranged to be about 1/2 of the depth of the middle region of the urine discharging dish 129. In this case, the middle region of the urine discharging tray 129 is constantly in the urine, so that the lower end of the film tube 125b is submerged in the urine.

At this time, the urine accumulated on the upper surface of the urine discharging dish 129 is replaced with fresh urine since at least one user discharges the urine at a predetermined time interval. Therefore, odor is not generated from the urine on the upper surface of the urine discharging dish 129.

When the urine is moved along the film tube 125b, the lower ring 125c is moved at a distance between the lower end of the film tube 125b and the bottom surface of the urine discharge tray 129, And is supplied to the urine drainage pipe 140. [0064]

The operation of the waterless urinal 100 according to the present invention having such a configuration will be described with reference to Figs. 1 to 5. Fig.

When the user pours urine into the urinal body 110, the urine is discharged to the discharge cap 123 coupled to the urine discharge port 111. The urine is moved to the film tube 125b through the urine discharge hole 123b. The film tube 125b is vertically supported by the upper ring 125a and the lower ring 125c to maintain the shape of the circular tube in the insertion tube 121b. The urine is moved to the inside of the film tube 125b and dropped onto the upper surface of the urine discharging dish 129. [

The urine is raised on the urine discharge tray 129 and moved to the space between the lower end of the film tube 125b and the bottom surface of the urine discharge tray 129 to be overflowed to the urine discharge tube 140 and discharged.

Since the diameter of the urine discharging tray 129 is formed to correspond to the diameter of the urine discharging tube 140, the odor moved upside down along the urine discharging tube 140 is discharged to both the outer peripheral edge of the urine discharging tray 129 and the urine discharging tube 140 in a narrow space.

On the upper surface of the urine discharging tray 129, the urine is always kept at a certain depth, so that the urine is diluted in the urine even if the odor is introduced. In addition, since the film tube 125b is vertically disposed in the urine, the malodor is blocked by the film tube 125b and prevented from moving upward.

Thus, it is possible to prevent the odor moving upward through the urine drain pipe 140 from flowing back to the urinal main body 110.

It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims. There will be. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
