Description

  The present invention relates to a urinal having an eye plate.

  Conventionally, the eye plate that is detachably attached to the bottom of the bowl portion of the urinal has been formed of pottery. When the eye plate is made of earthenware, when the eye plate is attached or detached for maintenance such as cleaning, the eye plate hits the bottom of the bowl, etc., and is easily damaged. There was a problem. For this reason, in recent years, eye plates made of a synthetic resin that is less likely to be damaged and lighter in weight than those made of earthenware have been used (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 9-021163

  As a synthetic resin used as a material for the eye plate, for example, polyvinyl chloride, melamine resin, or the like is used. Since these synthetic resins have water repellency, water in contact with the surface of the eye plate is repelled on the surface of the eye plate and easily becomes polka dots due to the surface tension of the water itself. Therefore, the eye plate made of synthetic resin has a problem that the wash water does not spread over the entire upper surface of the eye plate when washing with the wash water supplied in the urinal, and a portion that is not washed easily occurs. there were

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a urinal capable of making it difficult to form a portion that is not washed with washing water on the surface of the eye plate.

  The present invention includes a bowl portion that opens upward and receives supply of cleaning water, a concave portion provided at the bottom of the bowl portion, a drain tube that is erected on the bottom surface of the concave portion, and that is open upward and downward, and is attached to the concave portion. And a plurality of inlets that are formed between the eye plate and the opening edge of the recess to allow cleaning water to flow into the recess, and a top plate that covers the drain tube and the recess. The highest position of the upper open end of the drainage pipe is a position above the inlet located at the lowest position among the plurality of inlets, and the upper side of the drainage pipe. The lowest position of the opening end is a urinal which is a position below the lower end of the lower surface which is the lowest position on the lower surface of the top plate portion of the eye plate.

  In the present invention configured as described above, the highest position of the upper open end of the drain tube is located above the lowest inlet among the plurality of inlets, so that the bowl portion is washed. When water is supplied, the water level of the washing water staying in the recess rises above the inlet at the lowest position. For this reason, the cleaning water can easily collect on the upper surface of the eye plate, and the cleaning water can be easily distributed to the entire upper surface of the eye plate by continuously supplying the cleaning water toward the accumulated cleaning water. In addition, since the lowest position of the upper open end of the drain tube is positioned below the lower end of the lower surface, which is the lowest position on the lower surface of the top plate portion of the eye plate, when the cleaning water is not supplied to the bowl portion The level of the cleaning water remaining in the recess can be made lower than the upper surface of the eye plate. Therefore, it is possible to avoid a situation in which water is present on the eye plate in a state where no cleaning water is supplied, and the user is not given a sense of incongruity.

  In the present invention, the open end surface of the upper open end of the drainage pipe may be inclined at a predetermined angle with respect to a horizontal plane, and the predetermined angle is such that the highest position of the open end is in the plurality of inlets. At an angle above the inlet at the lowest position, and the position at which the lower end of the opening end is lower than the lower end at the bottom of the top plate of the eye plate. Is the angle.

  In the present invention configured as described above, the water level of the cleaning water remaining in the recess when the cleaning water is supplied into the bowl portion is lower than the inlet at the lowest position due to the inclined shape of the upper end face of the drainage cylinder. When the cleaning water is not supplied to the bowl portion, the water level of the cleaning water accumulated in the recess can be made lower than the lower end of the lower surface of the top plate portion of the eye plate.

  In the present invention, the upper end of the drain tube may be provided with a notch that partially lowers the upper open end of the drain tube, and the lowest position of the open end It is the position of the bottom of the notch.

  In the present invention configured as described above, the level of the cleaning water that remains in the recess when the cleaning water is supplied to the bowl portion is raised by the opening end on the upper side of the drainage tube from the lowest inlet. By the notch portion, the level of the cleaning water remaining in the recess when the cleaning water is not supplied to the bowl portion can be made lower than the lower end of the lower surface of the top plate portion of the eye plate.

  According to the urinal of the present invention, it is possible to make it difficult to form a portion that is not washed with washing water on the surface of the eye plate.

  As shown in FIGS. 1 to 3, a urinal 1 according to an embodiment of the present invention includes a bowl portion 2, a recessed portion 4 provided in a bottom portion 2 a of the bowl portion 2, and a bottom surface of the recessed portion 4. The drainage cylinder 6 is opened up and down, the washing water supply means 8 supplies the washing water to the bowl part 2, and the synthetic resin pan 10 attached to the recess 4 and covers the drainage cylinder 6 and the recess 4.

  The bowl part 2 is a bowl shape opened upwards, and receives excrement etc. which the user excreted. The bowl part 2 receives supply of cleaning water from the cleaning water supply means 8 in order to clean excrement and the like. The recessed part 4 is a recessed part formed in the approximate center of the bottom part 2a of the bowl part 2, and it inclines so that an opening end surface may rise toward the back from the front. Further, a step 4 a is formed on the upper edge of the recess 4.

  Although the details will be described later, the drain tube 6 has a substantially cylindrical shape opened up and down, and is erected at the center of the recess 4 so as to penetrate the bottom surface of the recess 4. That is, the opening at the upper end of the drain tube 6 is located above the bottom surface of the recess 4, the opening at the lower end of the drain tube 6 is positioned below the bottom surface of the recess 4, and the drain tube 6 is located in the recess 4. The inside and outside of the recess 4 are communicated with each other through the bottom surface. In the present embodiment, the case where the drain tube 6 is formed integrally with the bottom 2a and the recess 4 of the bowl portion 2 is shown. However, the present invention is not limited to such an embodiment. It may be formed of a resin or the like and separated.

  The washing water supply means 8 is provided at the upper part of the bowl part 2. The cleaning water supply means 8 supplies cleaning water supplied from a water source (not shown) such as a water pipe via an opening / closing valve (not shown) such as a flash valve that operates by detecting a cleaning start operation by the user. Water is discharged downward along the wall surface.

Next, with reference to FIG.4 and FIG.5, the detail of the eye plate 10 in one Embodiment of this invention is demonstrated. FIG. 4A is a top view showing a urinal eye plate in one embodiment of the present invention, FIG. 4B is a right side view showing a urinal eye plate in one embodiment of the present invention, and FIG. FIG. 5 is a cross-sectional view taken along the line B-B in FIG. 2.
As shown in FIG. 4, the eye plate 10 includes a substantially flat plate-shaped main body portion 10 a (top plate portion) and a cylindrical portion 10 b that protrudes downward from the lower surface of the eye plate main body portion 10 a.

  The eye plate main body 10a is formed to be inclined so that the upper surface rises from the front toward the rear. The rear end of the eye plate main body 10a is a straight line straight to the left and right, and the left end and the right end are forward so as to increase the width in the left and right direction linearly from the left and right end parts of the rear end to the substantially central part in the front-rear direction. The front half of the front half in the front-rear direction has a semicircular shape that draws an arc toward the front. Ribs 10c and 10c are respectively formed near the left front end and near the right front end of the lower surface of the eyepiece main body 10a.

  Moreover, as shown in FIG. 5, the eyepiece recessed parts 10d1-10d4 are formed in the edge part of the lower surface of the eyepiece main-body part 10a. The eyepiece recesses 10d1 and 10d2 are formed at the left and right ends on the rear side of the ribs 10c and 10c, and the eyepiece recesses 10d3 and 10d4 are formed at the left and right ends on the front side of the rib 10c. Each of the eyepiece recesses 10d1 to 10d4 has a shape that is recessed toward the substantial center on the lower surface of the end of the eyeglass main body 10a, and the lower end is open. By forming these eyepiece recesses 10d1 to 10d4, the ribs 10c at the left and right ends and the rear lower surface of the eyepiece main body 10a abut against the step 4a of the recess 4 when the eyeglass 10 is attached to the recess. However, a gap 12 is formed between the lower surface on the front side of the eye plate main body 10a and the step 4a on the front side of the recess 4 (see FIG. 3). The gap 12 and the eyepiece recesses 10 d 1 to 10 d 4 function as an inflow port through which the cleaning water flows into the recess 4.

  In addition, an attachment / detachment operation portion 10e protruding upward is formed at the center of the upper surface of the eye plate main body portion 10a. A through hole 10f penetrating from the left side surface to the right side surface of the attaching / detaching operation portion 10e is opened, and a hook or the like can be hooked on the through hole 10f. Thereby, the eye plate 10 can be easily attached to and detached from the recess 4.

  The cylindrical part 10b has a substantially cylindrical shape with the upper end connected to the lower surface of the eye plate main body part 10a and the lower end opened. For this reason, the upper end of the cylindrical part 10b inclines so that it may rise toward the back from the front so that the inclination of the eyepiece main-body part 10a may be followed. Further, the cylindrical portion 10 b is fitted into a concave space formed by the inner peripheral wall surface and the bottom surface of the concave portion 4 and the outer peripheral wall surface of the drain tube 6 when the eye plate main body portion 10 a is attached to the concave portion 4.

  Further, the inner diameter of the cylindrical portion 10b is larger than the outer diameter of the drainage cylinder 6, and the cylindrical portion 10b is disposed so as to surround the outer side of the drainage cylinder 6 when the eye plate main body portion 10a is attached to the recess 4. The lower end of the cylindrical portion 10 b is positioned below any part of the upper end of the drainage cylinder 6 and has a length that does not reach the bottom surface of the recess 4. A substantially constant gap is formed between the drain tube 6 and the tubular portion 10b, and the drain tube 6 and the tubular portion 10b have a substantially coaxial positional relationship. Thereby, a drainage trap is formed by the cylindrical portion 10 b, the inner peripheral wall surface and the bottom surface of the recess 4, and the outer peripheral wall surface of the drainage cylinder 6.

Next, with reference to FIG. 6, the detail of the drain pipe 6 in one Embodiment of this invention is demonstrated.
FIG. 6 is a partially enlarged view of FIG.
The opening end surface 6a of the upper opening end of the drain tube 6 is inclined at a predetermined angle R with respect to the horizontal plane so as to rise from the front toward the rear.

  The predetermined angle R is the lowest position of the lower end of the gap 12 where the height position L6 of the upper end of the inclined opening end surface 6a is the lowest position in the gap 12 functioning as an inflow port and the eyepiece recess 10d (10d1 to 10d4). The angle is higher than the height position L2. Furthermore, the predetermined angle R is the height of the lower end of the lower end of the lower end of the inclined opening end surface 6a, the lower end of the lower end of the inclined main plate body 10a, that is, the height of the foremost lower end of the main plate main body 10a. The angle is lower than the position L4. The height position L4 is the same height position as the height position L2. That is, the height position L6 that is the highest position of the upper opening end of the drain tube 6 due to the inclination of the opening end surface 6a is higher than the gap 12 that is the lowest inlet among the plurality of inlets. And the height position L0, which is the lowest position of the upper opening end of the drain tube 6 due to the inclination of the opening end surface 6a, is lower than the height position L4 of the foremost lower end of the eyepiece main body 10a. Thus, the inclination angle (predetermined angle R) of the opening end face 6a is set. The predetermined angle R is substantially the same as the inclination angle of the eye plate main body 10a. In the present embodiment, the height position L2 and the height position L4 are the same height, but the present invention is not limited to such a form, and the height position L2 and the height position L4 are different from each other. It may be height.

  The opening at the lower end of the drain tube 6 communicates with a pipe (not shown) arranged in the wall surface of the building and the like so that excrement and the like can be discharged.

Hereinafter, the operation of the urinal 1 in one embodiment of the present invention will be described with reference to FIGS. FIG. 7A is a cross-sectional view showing the water level when the urinal is washed in one embodiment of the present invention, and FIG. 7B is a cross-sectional view showing the water level when the urinal is stopped in one embodiment of the present invention. .
When a user performs a cleaning start operation on an on-off valve (not shown) such as a flush valve, the cleaning water is supplied from a water source (not shown) to the cleaning water supply means 8 provided above the bowl portion 2. Is supplied via an on-off valve. The supplied cleaning water is discharged to the bowl portion 2 by the cleaning water supply means 8, and the cleaning water spreads over the entire inner surface of the bowl portion 2. The excrement received in the bowl part 2 flows to the bottom part 2a of the bowl part 2 together with the washing water.

  A part of the washing water including excrement and the like that has flowed from the bottom 2a of the bowl portion 2 flows from the rear side of the upper surface of the eye plate main body portion 10a to the front side, and the front side of the eye plate main body portion 10a and the recess 4 It flows into the recessed part 4 from the clearance gap 12 between the level | step differences 4a, and the eyepiece recessed part 10d (10d1-10d4) of the lower surface of the eyepiece main-body part 10a. The washing water flowing into the recess 4 passes through the drain tube 6 and is discharged from the lower end opening of the drain tube 6 to a pipe (not shown). Moreover, in the recessed part 4, since the opening end surface 6a of the upper end of the drain tube 6 inclines upwards and is close to the lower surface of the eyeplate main-body part 10a, especially washing water is drained on the back side. The water level in the recess 4 gradually rises. Due to the rise in the water level, as shown in FIG. 7 (a), the water level of the cleaning water becomes a cleaning water level WL2 that is a position that exceeds a part of the lower side of the upper surface of the eye plate main body 10a, and the eye plate main body 10a. Wash water accumulates on the front portion of the upper surface. In this way, the washing water collected on the eye plate main body 10a makes it difficult for the washing water to flow into the recess 4 from the gap 12 and the eye dish recess 10d, and is discharged from the collected washing water and the washing water supply means 8. As the washing water merges, the washing water spreads over the entire upper surface of the eye plate main body 10a.

  When water discharge from the cleaning water supply means 8 stops, the water level of the cleaning water at the bottom 2a of the bowl portion 2 gradually decreases. Due to the lowering of the water level, as shown in FIG. 7B, the water level of the washing water is the lowest at the height position of the lower end of the open end surface 6 a at the upper end of the drain tube 6, that is, at the upper open end of the drain tube 6. It becomes the water level WL0 at the time of still water which is the same height position as the position.

  In the urinal 1 according to the embodiment of the present invention described above, the opening end surface 6a of the drain tube 6 is inclined by a predetermined angle R. The predetermined angle R is such that the highest position of the upper open end of the drain tube 6, that is, the height position L6 of the upper end of the open end face 6a is the lowest position in the gap 12 and the eyepiece recess 10d. It is an angle located above the lowest position height position L2. Therefore, it is difficult for the washing water to enter the drain tube 6 and the washing water is difficult to be discharged from the drain tube 6, so that the water level in the recess 4 is raised so that the level of the washing water is equal to the upper surface of the eyeplate main body 10 a. It can be raised above the part. As the washing water level rises, washing water accumulates in the front portion of the upper surface of the eye plate main body 10a. The accumulated cleaning water makes it difficult for the cleaning water to flow into the recess 4 from the gap 12 and the eye dish recess 10d, and the accumulated cleaning water and the cleaning water discharged from the cleaning water supply means 8 merge to form the eye. The washing water easily spreads to the upper surface of the dish body 10a. Therefore, the washing water can be distributed evenly over the entire upper surface of the eye plate 10, and it is possible to make it difficult to form a portion that is not washed on the upper surface of the eye plate 10 having water repellency. Further, the predetermined angle R is the lowest position at the lowest position of the upper opening end of the drain tube 6, that is, the height position L0 of the lower end of the opening end surface 6a is the lowest position on the lower surface of the eye plate main body 10a of the eye plate 10. Since the angle is lower than the height position L4 (L2) of the lower end, when the cleaning water is not supplied by the cleaning water supply means 8, the water level of the cleaning water accumulated in the recess 4 is higher than the upper surface of the eye plate 10. Can also be down. Therefore, it is possible to avoid a situation in which water is present on the eye plate 10 in a state in which no washing water is supplied, and the user is not given an uncomfortable feeling before and after use.

  Furthermore, the predetermined angle R which is the inclination angle of the opening end surface 6a of the drain tube 6 is substantially the same as the inclination angle of the eye plate main body 10a. Thereby, when attaching and detaching the eye plate 10, since the upper surface of the cylindrical part 10b and the upper end of the drain pipe 6 are hard to contact, it is easy to work and it is hard to produce the damage by contact. Moreover, according to the structure which inclines the upper opening end surface of the drain pipe 6 with respect to a horizontal surface, when attaching the height to the height position of the upper opening end of the drain pipe 6, the simple shape that the opening end face 6a inclines. Therefore, it is easy to produce a toilet part including the drain tube 6.

  In the present embodiment, the opening end surface 6a of the drain tube 6 is inclined at a predetermined angle R, so that a part of the upper end of the drain tube 6 has a plurality of inlets (gap 12 and eyepiece recess 10d (10d1 to 10d4)). And the other part of the upper end of the drain tube 6 is the lowest position on the lower surface of the eye plate main body 10a of the eye plate 10 and the inflow port located at the lowest position (the lowermost end of the gap 12). However, the present invention is not limited to such a form.

  A modification of the urinal according to the present embodiment will be described with reference to FIG. Fig.8 (a) is sectional drawing which shows the modification of the urinal in one Embodiment of this invention, (b) is P view of (a).

  In the urinal of this modification, instead of inclining the opening end surface of the drain tube 6 as described above, the upper end of the drain tube 6 is provided with a notch 6b at the upper end of the drain tube 6. A height difference is provided at the height position. That is, in the urinal of this modified example, the upper end portion of the drain tube 6 is provided with a notch 6 b that partially lowers the upper open end of the drain tube 6. The lowest position of the end is the position of the bottom (bottom surface) of the notch 6b.

  Specifically, as shown in FIGS. 8A and 8B, the upper end of the drain tube 6 is positioned higher than the foremost end of the gap 12, and the upper end of the drain tube 6 is positioned at the forefront of the main body 10a. A notch 6b extending to a position below the lower end is provided. In the drain tube 6, the position of the bottom (bottom surface) of the notch 6 b is the lowest position of the upper open end of the drain tube 6, and a position below the lower end of the lower surface of the eyepiece main body 10 a. Become. Here, in this case, when the cleaning water is supplied from the cleaning water supply means 8, the water level of the cleaning water becomes the cleaning water level WL2 above a part of the upper surface of the eye plate 10, and when the cleaning water is not supplied, the water level is turned off. It becomes the water level WL0 at the time of water stop which is the lower end position of the notch 6b. Thereby, as mentioned above, the same effect as the case of the structure which provides height at the height position of the upper open end of the drain pipe 6 can be obtained by inclining the open end face of the drain pipe 6.

  In the example shown in FIG. 8, the notch 6b has a substantially rectangular shape and is provided on the rear side (the right side in FIG. 8A) at the upper opening end of the drain tube 6. The shape and arrangement position of the notch 6b are not particularly limited. In addition, as a configuration for providing a height at the height position of the upper open end of the drain tube 6, a configuration in which a notch portion is provided as in this modification, and an open end surface 6 a of the drain tube 6 as described above. The structure which combined the structure which gives an inclination may be sufficient.
