Description

The present invention relates to a urinal.

Conventional urinals generally have a drainage port provided in the center of the bottom surface of the urinal bowl, as disclosed in Patent Document 1 and the like. This drainage port has a shape such as a substantially circular shape or a substantially rectangular shape, and is usually provided with a perforated plate having substantially the same shape as the drainage port.

Japanese Unexamined Patent Publication No. 7-207740

However, the drainage port is generally large to secure the amount of drainage, and even if a perforated plate with a relatively simple surface is attached, its outline shape is easy to see, so it is hard to say that it has a neat appearance. It has become a thing. In addition, the bottom surface of the toilet bowl is difficult to clean because there is a dent or a step in the center of the bowl due to the drain port.

The present invention has been proposed in consideration of such circumstances, and an object of the present invention is to provide a urinal that can express a neat aesthetic appearance and can easily clean the bottom surface on which a drainage port is formed. There is.

In order to achieve the above object, the urinal of the present invention is a urinal in which a urinal bowl having an open front surface is provided in the urinal body, and the urinal bowl has a substantially vertical plane with a part of the inner wall surface facing forward. As described above, the front surface is open, and an elongated drainage port leading downward is formed in the vicinity of the inner wall surface on the bottom surface of the urinal bowl, and the drainage port is further provided with a removable perforated plate. The urinal body is configured to have a bottom with the bottom as the upper end surface, and the drainage port leads to a vertical drainage passage formed inside the bottom, and the perforated plate is the longitudinal side of one of them. The edge is fixed to the opening edge in the longitudinal direction of the drainage port, and the other longitudinal edge is fixed in the vertical drainage passage and at a position lower than one edge .

According to the urinal of the present invention, since it has the above-described configuration, a neat appearance can be expressed, and the central portion of the bottom surface of the toilet bowl does not require a discharge port, and the central portion has a step or a dent. Since it can be a flat surface or a curved surface without such a surface, it is easy to clean.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
First, the outline basic configuration common to the urinals according to the plurality of embodiments described in the present specification will be described.

The urinals according to the first embodiment are shown in FIGS. 1 to 3, the urinals according to the second embodiment are shown in FIG. 4, the urinals according to the third embodiment are shown in FIG. 5, and other embodiments ( The urinal according to 3 cases) is shown in FIG. Since the appearance of each urinal according to the second, third and other embodiments is the same as that shown in the perspective view in FIG. 1 (a), the illustration of those external views is omitted. Further, FIGS. 3 (a) (b), 4 (b) (c) and 5 (b) (c) are cross-sectional views, but the end faces are schematically and schematically shown. , The addition of hatching is omitted. In the description of the urinal according to the following embodiment, the opening side of the urinal body 10 is defined as the front, and the back side is defined as the back.

These urinals are urinals for men's urinals in which the urinal body 10 is provided with a urinal bowl 20 having an open front surface. An elongated drainage port 30 leading downward is formed in the vicinity of the wall surface 22 (inner wall surface) on the bottom surface 21 (inner bottom surface) of the toilet bowl 20 (see FIGS. 1 to 6). Here, it is desirable that the elongated shape of the drainage port 30 has an elongated slit shape substantially along the outer peripheral edge 21b of the bottom surface 21, as in each example of the following embodiments. Therefore, it is desirable that the drainage port 30 has an elongated shape that does not reach the central portion (central portion) of the bottom surface 21.

As described above, in these urinals, the drainage port 30 is not formed in the central portion of the bottom surface 21, but an elongated one is formed in the vicinity of the wall surface 22 on the bottom surface 21. Therefore, the 20 faces of the urinal bowl can be made to have a neat and aesthetic appearance. Further, since the drainage port is not formed in the central portion of the bottom surface 21 and the central portion is a flat surface or a curved surface without steps or dents, it is easy to clean.

The bottom surface 21 of the toilet bowl 20 is continuous with the wall surface 22 of the wall portion ( the back surface portion 11, the side wall portion 14, and the front wall portion 15 described later) that rises from the outer peripheral edge 21b, and the inside corner portion is urine. It has a curved surface to facilitate the flow of cleaning water (hereinafter referred to as water, etc.). The drainage port 30 is formed at any portion of the outer peripheral portion 21a of the bottom surface 21 including the curved surface-shaped entrance corner portion. Of course, considering the flow of water, it goes without saying that the drainage port 30 is arranged at the lowest position on the bottom surface 21.

Next, the details of the urinal according to the first embodiment illustrated in FIGS. 1 to 3 will be described.

As shown in FIGS. 1 and 2, the urinal body 10 has a back surface portion 11, an upper surface portion 12, a bottom portion 13, a side wall portion 14, and a front wall portion 15, and a toilet bowl bowl 20 is formed by these. .. That is, as shown in FIG. 1A, the toilet bowl 20 is provided with a recess having an open front surface and a continuous inner surface (wall surface 22, bottom surface 21). A cleaning nozzle 17 for discharging cleaning water is provided on the upper portion of the wall surface 22 on the back surface 11 side of the toilet bowl 20.

The bottom surface 21 of the toilet bowl 20, which is the upper end surface of the bottom portion 13, has its entire outer peripheral edge 21b connected to the wall surface 22. As shown in FIGS. 1A and 2A, the bottom surface 21 is located lower than the upper end of the front wall portion 15 and cannot be visually recognized from the front.

As shown in the cross-sectional view of FIG. 2 (c) and FIG. 1 (b), the bottom surface 21 of the toilet bowl 20 has a substantially triangular curved shape and has a shape that narrows toward the front. .. At the rear portion of the outer peripheral portion 21a of the bottom surface 21, a slit-shaped drainage port 30 having a horizontally long slit shape is formed substantially along the outer peripheral edge 21b. The drainage port 30 shown in FIG. 2C is provided so as to be in contact with the wall surface 22. The bottom surface 21 and the wall surface 22 are continuous with each other through a curved inside corner 23 (exemplified in FIG. 6 (c)). The discharge port 30 may be an opening extending from the bottom surface 21 to the wall surface 22 via the entrance corner 23.

Further, the drainage port 30 does not have to be formed so as to be in contact with the outer peripheral edge 21b, and as shown by the alternate long and short dash line in FIG. 1B, the drainage port 30 is located at a portion of the outer peripheral portion 21a slightly distant from the outer peripheral edge 21b. It may be formed.

The bottom surface 21 of the toilet bowl 20 is inclined downward from the front portion toward the drain port 30, and water or the like flows as shown by the broken line arrows in FIGS. 1 (b) and 3 (a). That is, most of the water or the like that has fallen directly to the bottom surface 21 or along the wall surface 22 to the bottom surface 21 flows toward the drain port 30.

Further, as described above, the urinal body 10 includes a bottom portion 13 having a bottom surface 21 as an upper end surface. As shown in FIG. 3A, the drainage port 30 leads to a vertical drainage passage 31 formed in the internal space of the bottom portion 13. The vertical drainage passage 31 is a drainage channel through which water or the like flows from top to bottom, and the front and rear dimensions of the drainage channel are sufficiently larger than the dimensions of the drainage port 30. That is, the cross section of the vertical drainage passage 31 is larger on the lower side than the drainage port 30 side. Further, the passage surface on the back side of the vertical drainage passage 31 is formed so as to be continuous downward from the wall surface 22 on the back surface 11 side of the toilet bowl 20 without a step.

A U-shaped drain trap 32 is formed on the downstream side (lower side) of the vertical drain passage 31. When water or the like flows down from the drainage port 30, the water or the like that has passed through the vertical drainage passage 31 flows to the external drainage channel 37 via the drainage trap 32. Further, when water or the like does not flow to the drain port 30, the state in which water or the like is accumulated in the drain trap 32 is maintained. The accumulated water blocks the odor flowing back from the external drainage channel 37. In addition, it is desirable that the capacity of the stored water of the drain trap 32 is such that it flows to the outside by one washing so that urine does not remain in the drain trap 32 at the time of drainage.

As described above, this urinal has a configuration in which a drainage port 30 elongated in the lateral (left-right) direction is provided behind the bottom surface 21 of the toilet bowl 20, but the center of the bottom portion 13 is below the center portion of the bottom surface 21. A large drainage passage space (reservoir space) is formed using the part. With such a configuration, there is no possibility that water will overflow from the slit-shaped drain port 30 even when a large amount of washing water is flowed. Further, since the pooled water portion (drainage trap 32) having a sufficient capacity is formed by using the central portion of the inner space of the bottom portion 13, it is possible to prevent the backflow of odor.

A thin vertical drainage passage 31 having a small size in the front-rear direction may be provided according to the shape of the drainage port 30. By doing so, the bottom portion 13 can be made thinner (the front-rear dimension can be made smaller) accordingly, and a thin urinal can be formed as a whole.

Further, a perforated plate 33 (not shown in plan view of the perforated plate 33) that substantially matches the overall length of the elongated shape in the longitudinal direction is detachably attached to the drain port 30. As shown in FIG. 3A, one of the longitudinal edges (the edge on the one end side in the width direction) of the perforated plate 33 is fixed to the opening edge 30a in the longitudinal direction of the drain port 30. There is. Further, the other longitudinal edge of the perforated plate 33 is fixed in the vertical drainage passage 31 and at a position lower than the one longitudinal edge.

In this urinal, as shown in FIG. 3A, the perforated plate 33 is attached so as to descend and incline to the rear side. The means for fixing the perforated plate 33 to the drain port 30 is not particularly limited, and it may be just hooked or placed. Of course, it is desirable that at least it does not come off due to the flow of washing water.

Since the perforated plate 33 is tilted and attached in this way, a large perforated plate 33 can be arranged even with the slit-shaped drain port 30. Therefore, it is possible to sufficiently secure the ability to dam the dust. Further, if the perforated plate 33 is attached with a downward inclination to the rear side as in the example of FIG. 3, it is hardly visible to a person in a small standing position and looks good, but the eye plate 33 is downwardly inclined to the front side. You may arrange it.

Further, as shown in FIG. 3B, the perforated plate 33 is moved up and down by remote control. That is, the urinal body 10 is assembled with an operation unit 34 and an operation mechanism 35 for operating the perforated plate 33. The operation unit 33 is provided on the upper surface portion 12 or the like, and is connected to the perforated plate 33 via an operation mechanism 35 including a wire 35a.

The one in this example is a so-called pop-up type, and when the operation unit 34 is pushed down, the eye plate 33 moves upward to open the drain port 30, and when the operation unit 34 is pulled up, the eye plate 33 moves downward. It moves to the position of and becomes a state of acting as a perforated plate 33. The vertical movement of the perforated plate 33 is not limited to the push / pull operation, and may be a so-called push type in which the vertical movement of the perforated plate 33 is alternately repeated by a continuous operation of only the pushing operation. Further, as the operation mechanism, a link type in which the link material is moved by the operation of the operation unit to move the cover up and down may be adopted, or an electric type, a hydraulic type, or the like may be adopted.

Since the perforated plate 33 moves up and down by remote control in this way, the perforated plate 33 can be easily removed by moving it upward during cleaning. Further, if the perforated plate 33 is greatly lifted upward, the vicinity of the drain port 30 can be cleaned without removing the perforated plate 33. That is, the perforated plate 33 may not be removable.

Next, the urinal according to the second embodiment will be described with reference to FIG.

In this urinal, the drain port 30 is formed in the front portion of the outer peripheral portion 21a of the bottom surface 21 of the toilet bowl 20. Water or the like flows toward the drain port 30 as shown by the broken line arrows in FIGS. 4A and 4B. The drainage port 30 shown in FIG. 4A is formed so as to be in contact with the outer peripheral edge 21b, but if it is a portion of the outer peripheral portion 21a in the vicinity of the bottom surface 21 and the wall surface 22 of the front wall portion 15, For example, it may be a portion indicated by a two-dot chain line.

In this way, since the drainage port 30 is formed in the vicinity of the wall surface 22 of the front wall portion 15, the drainage port 30 tends to be a blind spot for the user of the urinal, and is clean and neat for the user. Can make an impression.

Further, the drainage port 30 leads to a vertical drainage passage 31 formed in the internal space of the bottom portion 13. The front and rear dimensions of the vertical drainage passage 31 gradually increase downward, that is, the cross section of the vertical drainage passage 31 is larger on the lower side than the drainage port 30 side, and the lower side is stored water. It can be used as a part (drainage trap 32).

As described above, since the drainage port 30 is formed in the front portion of the bottom surface 21 of this urinal, the space of the drainage trap 32 is secured below the central portion behind the drainage port 30 as in the present embodiment. It is possible to form a thin urinal as shown in FIG. In the case of the conventional type in which the drainage port is provided in the central part of the bottom surface 21, the drainage trap 32 must be provided in the rear part of the central part, and it is obvious that the drainage trap 32 is thicker than that of this example.

Further, a perforated plate 33 (not shown in plan view of the perforated plate 33) that substantially matches the overall length of the elongated shape in the longitudinal direction is detachably attached to the drain port 30. As shown in FIG. 4B, in the perforated plate 33, the longitudinal edge on the bottom surface 21 side is fixed to the opening edge 30a on the rear side of the drain port 30. Further, the other longitudinal edge of the perforated plate 33 is fixed in the vertical drainage passage 31 and at a position lower than the one longitudinal edge. That is, the perforated plate 33 is attached so as to be inclined downward to the front side. The means for fixing the perforated plate 33 to the drain port 30 may be such that it is hooked or placed on the drain port 30, and it is desirable that the plate 33 is at least not dislodged by the flow of washing water.

Since the perforated plate 33 is tilted and attached in this way, a large perforated plate 33 can be arranged even with the slit-shaped drainage port 30, and a sufficient dust damming ability can be secured. Can be done.

Further, as shown in FIG. 4C, the perforated plate 33 is operated up and down by remote control. An operation unit 34 and an operation mechanism 35 for operating the perforated plate 33 are assembled to the urinal body 10. The operation unit 34 is provided on the front wall portion 15 and is connected to the perforated plate 33 via an operation mechanism 35 including a wire 35a.

Since the perforated plate 33 moves up and down by remote control in this way, the perforated plate 33 can be easily removed by moving it upward during cleaning. Further, if the perforated plate 33 is greatly lifted upward, the vicinity of the drain port 30 can be cleaned without removing the perforated plate 33.

Next, the urinal according to the third embodiment will be described with reference to FIG.

In this urinal, the drain port 30 is formed on the side portion (right side when facing the urinal) on the outer peripheral portion 21a of the bottom surface 21 of the urinal bowl 20. Water or the like flows toward the drain port 30 as shown by the broken line arrows in FIGS. 5A and 5B. The drainage port 30 shown in FIG. 5A is formed so as to be in contact with the outer peripheral edge 21b of the bottom surface 21, but is a portion of the outer peripheral portion 21a near the bottom surface 21 and the wall surface 22 of the front wall portion 15. If there is, for example, it may be a site indicated by a two-dot chain line.

Further, the drainage port 30 leads to a vertical drainage passage 31 formed in the internal space of the bottom portion 13. The distance between the left and right sides of the vertical drainage passage 31 is gradually increasing, that is, the cross section of the vertical drainage passage 31 is larger on the lower side than the drainage port 30 side, and the lower side is the water portion (drainage trap). It is configured to be used as 32).

Since the drainage port 30 is formed on the side portion of the bottom surface 21 in this way, the space of the drainage trap 32 can be secured below the central portion on the side of the drainage port 30. Since the central portion in the space of the bottom portion 13 can be used as a pool water portion in this way, the urinal can be made thinner as in the case of FIG.

Further, a perforated plate 33 (not shown in plan view of the perforated plate 33) that substantially matches the overall length of the elongated shape in the longitudinal direction is detachably attached to the drain port 30. Although the perforated plate 33 shown in FIG. 5B is installed parallel to the installation surface of the urinal, it is arranged in an inclined shape like the urinal according to the first and second embodiments. You may.

Further, as shown in FIG. 5C, the perforated plate 33 is moved up and down by remote control. An operation unit 34 and an operation mechanism 35 for operating the perforated plate 33 are assembled to the urinal body 10. The operation portion 34 is provided on the side wall portion 14, and is connected to the perforated plate 33 via an operation mechanism 35 including a wire 35a.

Since the perforated plate 33 moves up and down by remote control in this way, the perforated plate 33 can be easily removed by moving it upward during cleaning. Further, if the perforated plate 33 is greatly lifted upward, the vicinity of the drain port 30 can be cleaned without removing the perforated plate 33.

Next, three examples of urinals according to other embodiments will be described with reference to FIGS. 6A to 6C.

The urinal of FIG. 6A has a bent elongated shape in which the drain port 30 extends from one side portion to the other side portion via the front portion. Since this urinal has a larger opening area of the drain port 30 than the above-mentioned three types of urinals, it also has a large drainage capacity. Further, although the drainage port 30 is large, it is hidden by the front wall portion 15, so that the aesthetic appearance is not deteriorated. The bottom surface 21 has an inclination so that water or the like flows as shown by a broken line. Further, a perforated plate (not shown in this example) that matches the shape of the drainage port 30 may be attached.

The urinal of FIG. 6B has a drainage port 30 formed at the rear like that of FIG. The flow of water etc. is as shown by the broken line arrow. As shown in the partially enlarged vertical sectional view of FIG. 6B, an inclined drainage passage 31A is formed below the drainage port 30. The inclined drainage passage 31A extends downward from the wall surface 22 of the back surface portion 11. Further, one of the longitudinal edges of the perforated plate 33 is fixed to the opening edge 30a on the bottom surface 21 side of the drainage port 30, and the other longitudinal edge is fixed to the inclined surface of the drainage passage 31A, and is mounted in a substantially vertical state. There is.

Due to such a configuration, the inclined surface of the drainage passage 31A can be seen from above the drain port 30, but this inclined surface can be easily cleaned. Therefore, the inclined surface of the drainage passage 31A can be maintained in the same clean state as the other surface of the toilet bowl 20. Therefore, in a plan view, the aesthetic appearance can be expressed without distinguishing it from the bottom surface 21 and without a sense of discomfort. Also, the perforated plate 33 is inconspicuous.

In the urinal of FIG. 6C, the drainage port 30 is formed at a portion including the entrance corner 23 of the bottom surface 21 and the wall surface 22. According to such a thing, since the opening in the bottom surface 21 can be made small, the drainage port 30 is not conspicuous in a plan view, and it is possible to prevent the drainage port 30 from deteriorating the aesthetic appearance. Further, as shown by the broken line, the water flowing on the bottom surface 21 and the water flowing on the wall surface 22 can be efficiently drained.
