JP 2002-138559 A Japanese Unexamined Patent Publication No. 7-18718 JP 2002-61251 A JP 2009-74313 A

  In a urinal provided with a pan that has a through hole through which drainage flows into a circular lid, for example, effluent that has flowed in through the through hole provided in the pan is passed through the drain of the urinal. Because of the structure that only falls into the trap at the bottom, the urine concentration tends to remain high.

  When the concentration of urine in the sealed water stored in the trap at the bottom of the urinal is high, there is a risk of impairing the cleanliness of the toilet facilities due to the odor from the trap. Moreover, in order to reduce the concentration of manure in the wastewater stored in the trap, it is conceivable to increase the amount of water for washing, but this is not desirable from the viewpoint of cost and water saving.

  As a result of earnest research, the applicant of the present application focuses on an eye plate provided in the urinal, collects urinal washing water, and proposes a urinal eye plate that can be discharged in one direction.

  Therefore, the subject of the technique of an indication is to provide the technique of the eyeplate of the urinal which can collect the wash water of a urinal and can discharge in one direction.

  One aspect of the disclosed technology is exemplified by the following urinal eye dish configuration. That is, the urinal eye plate is a urinal eye plate that can be placed on the top of the trap opening at the bottom of the urinal body, and the eye plate descends from the outer peripheral edge of the eye plate toward the substantially central portion. Provide waterway.

According to such a configuration, the eyelet of the urinal can concentrate the wash water that has flowed into the bottom from the top of the urinal in the water conduit formed substantially at the center. Since the water guide path descends from the outer peripheral edge of the eye plate toward the substantially central portion, the collected cleaning water can be discharged downward along the inclination direction of the bottom from the tip part of the water guide path. The discharged wash water can create a flow that discharges to the sealed water with a high concentration of manure stored in the trap.

  According to the disclosed urinal eye plate, it is possible to provide the urinal eye plate technology that collects the urinal washing water and discharges it in one direction.

  Other objects, features and advantages will become apparent upon reading the detailed description set forth below when taken in conjunction with the drawings and the appended claims.

The upper wall surface 3 extends forward from the upper end of the urinal body wall surface 4 along the horizontal direction, and the distal end portion of the upper wall surface 3 and the outer wall surface 5 are formed continuously.

The drain port 6 is open at the bottom of the urinal body 2 and communicates with the trap 10 of the urinal 1. As illustrated in FIG. 1C, the lower part of the urinal body 2 is formed so that the two surfaces of the urinal body wall surface 4 intersect at the tip of the lip 2a. The drain port 6 has a substantially elliptical opening having a long axis in the direction from the tip of the lip portion 2a to the urinal body wall surface 4 facing the lip portion 2a.

  As illustrated in FIG. 2, a urinal plate 8 having a size covering the opening surface of the drain port 6 is detachably mounted on the drain port 6, and the upper surface of the trap 10 is placed by the eye plate 8. Covered. A specific description of the eye plate 20 will be described later.

  As illustrated in FIG. 2, the trap 10 communicates with a substantially S-shaped drainage pipe 11 to form a generally U-shaped drainage trap. The front side wall surface 10 a of the trap 10 is gradually curved toward the drain pipe 11 and is connected to a flat portion at the bottom of the trap 10.

[Eye plate composition]
FIG. 3 is a diagram illustrating the configuration of the eyeplate of the urinal according to one embodiment. 3A illustrates a perspective configuration diagram viewed from the front surface side of the eye plate, and FIG. 3B illustrates a perspective configuration diagram viewed from the back surface side of the eye plate. FIG. 3C illustrates a plan view of the eye plate, FIG. 3D illustrates a side view of the eye plate, and FIG. 3E illustrates a rear side view of the eye plate. A toilet bowl according to one embodiment has the shape disclosed in FIGS. 3A to 3E.

  The urinal eyeplate 8 of one embodiment forms a funnel-shaped lid that covers the opening of the drain port 6. When the eye plate 8 is placed on the opening surface of the drain port 6, the diameter of the eye plate 8 decreases from the upper part in the vertical direction toward the lower part, and inclines downward toward the outer side in the radial direction in the substantially central part. A water conduit 8e having a bottom portion is formed.

  The eye plate 8 is integrally formed by fan-shaped regions 8a, 8b, 8c, and 8d that have different radii of curvature and curve downward inward in the radial direction. The region 8a forms a bottom portion of the water conduit 8e that is inclined downward in the vertical direction by narrowing the fan-shaped region area while curving inward from the outer peripheral edge 8f in the radial direction. The region 8b forms a side portion of the water conduit 8e by narrowing the fan-shaped region area while curving downward from the outer peripheral edge 8f inward in the radial direction. The region 8c narrows the fan-shaped region area while curving downward from the outer peripheral edge 8f inward in the radial direction, and constitutes the upper opening end of the water conduit 8e. The region 8d forms a side portion of the water conduit 8e by narrowing a fan-shaped region area while curving downward from the outer peripheral edge 8f inward in the radial direction.

The area of the region 8a constituting the bottom of the water conduit 8e is preferably at least larger than the area of each of the regions 8b, 8c and 8d. By taking a large area of the area 8a, it is possible to increase the amount of water, such as cleaning water collected in the area 8a. As a result, the urinal plate 8
Can increase the momentum of the flow along the slope of the bottom of the water conduit 8e, such as washing water collected in the water conduit 8e.

  The fan-shaped regions 8a, 8b, 8c, 8d of the eye plate 8 and the water conduit 8e are integrally formed, and the side of the water conduit 8e constituted by the region 8b and the water conduit 8e constituted by the region 8d. Opposite to the side. In addition, as illustrated in FIG. 3E, the region 8b and the region 8d constituting the side portion of the water conduit 8e may be curved with the same radius of curvature.

  The water conduit 8e formed integrally with the fan-shaped regions 8a, 8b, 8c, 8d of the eye plate 8 protrudes on the back side of the eye plate 8, and the tip 8g of the protruded water conduit 8e opens in a substantially O-shape. ing. As illustrated in FIG. 3D, the opening surface of the tip 8g of the water conduit 8e is formed to have a predetermined inclination angle with respect to the vertical direction. This is because when the water drops and drops from the upper opening end of the water conduit 8e configured by the region 8c fall on the trap 10, they do not interfere with the bottom of the water conduit 8e configured by the region 8a. For example, the inclination angle of the opening surface is set to be approximately 60 degrees as the inclination angle R1 with respect to the horizontal plane.

  Moreover, as illustrated in FIG. 3C, the opening surface of the tip 8g of the water conduit 8e is formed at a position that is biased radially toward the region 8c. For example, as illustrated in FIG. 2, the region 8 c side is located in the direction of the user when the urinal 1 is used. For this reason, the opening surface (hole for draining into the trap 10) formed so as to have a predetermined inclination angle with respect to the vertical direction has a structure that is almost invisible to the user, and increases the odor from the trap. Can be suppressed.

  As illustrated in FIGS. 3A and 3B, the outer peripheral edge 8f of the eye plate 8 may be inclined in the thickness direction. As illustrated in the enlarged view surrounded by a two-dot chain line in FIG. 2, the eye plate 8 is fitted to a tapered step-like fitting structure 6 a provided around the opening of the drain port 6 of the urinal 1. By doing so, it becomes easy to attach to and detach from the urinal 1. Furthermore, the eye plate 8 can be attached so that the surface position of the bottom of the urinal 1 in which the drain port 6 is opened and the surface of the eye plate 8 are the same height.

  Further, the inclination in the thickness direction of the outer peripheral edge 8f of the eye plate 8 may be in accordance with the curved shape of the inner wall surface of the urinal body 2 in which the drain port 6 is opened. In this case, the size of the eye plate 8 can be attached to the urinal body 2 so as to cover the opening surface of the drain port 6. Since the eye plate 8 can be placed so that the inclined surface of the outer peripheral edge 8 f of the eye plate 8 is in contact with the curved inner wall surface of the urinal body 2, the urinal 1 to which the eye plate 8 is attached is provided with a drain port 6. The stepped fitting structure 6a provided around the opening can be omitted.

  As described above, the urinal eyeplate 8 of one embodiment forms a funnel-shaped lid that covers the opening of the drain port 6, so that the wash water that has flowed into the bottom from the top of the urinal 1 is used. , And can be concentrated on the water conduit 8e formed in the substantially central portion. The water conduit 8e is integrally formed with a plurality of regions constituting the eye plate 8, and when the eye plate 8 is placed on the opening surface of the drain port 6, the water conduit 8e descends obliquely with respect to the vertically downward direction. Therefore, it is possible to collect water while minimizing the decrease in the momentum of the water flow of the wash water that has flowed from the top of the urinal 1 to the bottom. Since the water conduit 8e has a bottom portion that is inclined downward toward the outside in the radial direction, the collected cleaning water can be discharged downward along the inclination direction of the bottom portion from the tip portion 8g of the water conduit 8e. .

  Drawing 4 is an explanatory view about the drainage of the urinal which attached the eye plate of one embodiment. Wash water or the like that has flowed from the top of the urinal 1 to the bottom is collected by the eye plate 8 that covers the drain port 6. The washing water is supplied to the urinal 1 through the inflow pipe 13, for example. The washing water supplied to the urinal 1 is discharged into the urinal body 2 at an appropriate timing and at an appropriate amount of water discharge at an appropriate timing by an unillustrated discharge means.

  The wash water collected by the eye plate 8 is discharged from the tip 8g of the water conduit 8e along the slope of the bottom of the water conduit 8e. The discharge direction of the wash water collected by the eye plate 8 is the inclination direction of the bottom of the water conduit 8e.

  The front side wall surface 10a of the trap 10 faces the opening surface of the tip 8g of the water conduit 8e. The wash water collected by the eye plate 8 is discharged from the front end 8g of the water conduit 8e to the front side wall surface 10a of the trap 10. The cleaning water discharged to the front side wall surface 10a of the trap 10 flows into the sealed water stored in the trap 10 along the curved wall surface of the front side wall surface 10a. The washing water that has flowed into the sealed water in the trap 10 creates a flow toward the drain pipe 11 while stirring the stored sealed water, and the sealed water in the trap 10 is connected to the drain pipe 11 that communicates with the rear of the trap 10. Discharge. The sealed water (and washing water) discharged to the drain pipe 11 is drained to a predetermined facility through an outlet pipe 12 communicated with the rear part of the drain pipe 11.

  As described above, the washing water discharged by the eye plate 8 of the embodiment can flow while stirring the sealed water having a high concentration of urine stored in the trap 10 and can be discharged to a predetermined facility. .

  In the drainage experiment conducted by the applicant, when a wash water of about 1 liter was poured into a urinal having a conventional eye plate structure, the residual concentration of the sealed water stored in the trap 10 was about 20%. It remained. The amount of sealed water in the trap 10 is about 0.7 liter. On the other hand, in the urinal equipped with the eye plate of one embodiment, when about 1 liter of washing water was allowed to flow, the residual concentration of the sealed water stored in the trap 10 was improved to about 10 percent. Furthermore, when about 3 liters of washing water was flowed as an additional experiment, the residual concentration of the sealed water stored in the trap 10 was improved until it could not be detected.

  Thus, according to the urinal equipped with the eye plate of one embodiment, it is possible to provide the technology of the urinal eye plate that can collect flush water of the urinal and discharge it in one direction. As a result, a urinal eye plate that can achieve both water saving and cleanliness can be realized.

  In addition, although the material of the eye plate of one Embodiment is based on resin-made plastics, it may be metal, such as stainless steel, and may be made from earthenware, such as a ceramic. In addition, according to the urinal equipped with the eye plate of one embodiment, since the flow toward the drain pipe 11 is created while stirring the stored sealed water, for example, it was precipitated in the sealed water in the trap 10. Spouts and the like are also effectively discharged by the flow created by the cleaning water discharged to the front side wall surface 10 a of the trap 10.
