Abstract

PROBLEM TO BE SOLVED: To prevent generation of a splash at water jetting time by forming inclined faces to jet wash water having an angle to a back wall surface in a water jetting port which is arranged in an upper part of the back wall surface of a urinal and jets wash water to the back wall surface. SOLUTION: A spreader 4 is provided with an inserting installing pipe part 4a inserted and installed in a back wall surface 1a of a urinal 1, a contact part 4b whose diameter is expanded from its tip and which comes into contact with a front face of the back wall surface 1a and a front covering cover part 4c. A water jetting port 5 is formed on the lower end side of the covering cover part 4c, and an inclined face 7 is also formed on an inside surface of the contact part 4b in parallel to an inclined face 6 formed on its inside surface, and an inclined passage R2 is formed by these parallel inclined faces 6 and 7. Therefore, wash water comes into contact with the covering cover part 4c, and flows in the inclined passage R2 along the inclined faces 6 and 7, and is jetted toward the back wall surface 1a from the water jetting port 5. At this time, in the inclined faces 6 and 7, since an angle is set to the back wall surface 1a, a water jet from the water jetting port 5 flows down along the back wall surface 1a without peeling off from the back wall surface 1a.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spreader structure in a urinal.

[0002]

2. Description of the Related Art Conventionally, as shown in a front view of FIG. 7 and a side sectional view of FIG. 8, a back wall surface 1 of a urinal 1 is shown.
A spreader 4 is attached to the upper part of a, and the spreader 4 is connected to a water supply pipe 2 connected to the upper surface of the urinal 1 via a hose 3 so that the cleaning water supplied from the water supply pipe 2 Water is sprayed from the spreader 4 onto the back wall surface 1a to wash the back wall surface 1a. As shown in an enlarged sectional view of FIG. 9, this conventional spreader 4 has a water spray port 5 formed in parallel with the back wall surface 1a. In the conventional structure as shown in FIG. There is a problem that the water spray does not have a rectifying effect so much and that the water spray is easily separated from the back wall surface 1a when the water supply pipe 2 side is under high pressure or when the water spray is started, and a droplet is easily generated.

[0003]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an enlarged cross-sectional configuration diagram of the spreader of the first embodiment. The spreader 4 of the present embodiment includes an insertion tube portion 4a inserted into the back wall surface 1a of the urinal 1 and the insertion tube portion. Four
It has an abutting portion 4b that expands from the tip of a and abuts against the front surface of the back wall surface 1a, and a cover lid portion 4c that covers the front surface.
The water spray port 5 is formed on the lower end side of the cover portion 4c,
An inclined surface 6 that is inclined is formed on the inner surface of the lower end portion of the cover portion 4c, and the contact portion 4 is parallel to the inclined surface 6.
An inclined surface 7 is also formed on the inner surface of b, and an inclined flow path R2 that is inclined by the parallel inclined surfaces 6 and 7 is formed.

Therefore, the wash water flowing from the wash water passage R1 from the side of the hose 3 connected to the water supply pipe 2 comes into contact with the cover lid portion 4c and flows along the inclined passages R2 along the inclined surfaces 6 and 7. Water is sprayed from the water spray port 5 toward the back wall surface 1a. At this time, since the inclined surfaces 6 and 7 are set at an angle with respect to the back wall surface 1a, the water spray from the water spray port 5 is performed at the back wall surface 1a.
It is surely flown down along the back wall surface 1a without being peeled off from a, and the number of splashes scattered to the front surface side of the back wall surface 1a unlike the conventional case is extremely reduced. It is desirable that the inclination angles of the inclined surfaces 6 and 7 are set so that the angle α at which the line passing through the center of the inclined flow path R2 contacts the back wall surface 1a is 45 ° or less. In addition,
2 is a cross-sectional view taken along the line AA of FIG. 1, and the water spray port 5 is formed in a fan shape so that the cleaning water can be sprayed over a wide range of the back wall surface 1a.

Next, FIG. 3 shows a modified example. In FIG. 3, an inwardly projecting piece 4d is integrally formed on the lower end of the cover portion 4c of the spreader 4 so as to horizontally project inwardly. An inclined surface 8 is formed at the inner end of the protruding piece 4d. Even if the inclined surface 8 is formed on the tip side of the water spray port 5 in this way, water is sprayed onto the back wall surface 1a in a slanting manner along the inclined surface 8 and the conventional droplets are generated. It is difficult and the wash water can be satisfactorily flown down along the back wall surface 1a.

Next, FIG. 4 shows a second embodiment.
In FIG. 4, a horizontal protrusion 4f is formed by horizontally projecting inside the cover 4c of the spreader 4, and
A vertical protruding piece 4g is formed in a hanging shape in the insertion tube portion 4a,
Further, an air hole 9 is formed so as to penetrate the upper surface portion 4e of the spreader 4, and inclined surfaces 6 and 7 are formed on the water spray port 5 side as in FIG. 1 to form an inclined flow path R2. The porous pressure reducing plate 10 and the net 11 are arranged at intervals in the washing water passage R1 in the insertion tube portion 4a. That is, the pressure reducing plate 10 is attached to the vertical protruding piece 4g, and the net 11 is fitted and fixed to the tip of the horizontal protruding piece 4f.

In the space between the pressure reducing plate 10 and the net 11, the air hole 9 side is arranged to communicate with each other. In such a structure, the cleaning water flowing through the cleaning water passage R1 is first of all. , And at that time the flow velocity is increased and the particles are diffused by the net 11. At that time, air is entrained from the air holes 9 to generate foam, and the foam water is jetted in an inclined shape from the water spray port 5 toward the back wall surface 1a through the inclined flow path R2. The spreader structure is less likely to be splashed when it collides with the wall surface 1a, and the spreader structure is less likely to generate splashes than the structure of FIG. 1. Moreover, the amount of washing water can be increased by mixing air into foam water. Even if the water content is small, a good cleaning effect can be obtained, and a water saving effect can be expected.

FIG. 5 is a sectional view of FIG. 4, in which a plurality of the air holes 9 are formed and a large amount of air is sucked in to obtain a better foam. In addition, when the pressure reducing plate 10 and the net 11 are internally provided in this way, it is difficult for droplets to come out even in the shape where the inclined channel R2 does not exist as shown in FIG. 6, and in FIG. The water spray port 5 is opened in parallel with the back wall surface 1a, and a large-diameter air hole 9 is formed on the upper surface of the spreader 4, so that a large amount of air is sucked in and foam is satisfactorily generated inside. It is configured as follows.

[0010]

The present invention is a spreader provided at an upper portion of a back wall surface of a urinal and equipped with a water spray opening for spraying washing water onto the back wall surface, wherein the water spray opening is provided with respect to the back wall surface. By forming an inclined surface that is capable of spraying wash water at an angle, water is sprayed from the spreader in an inclined shape with respect to the back wall surface of the urinal, so spraying is unlikely to occur as in the conventional case, The washing water can flow down well without being peeled off from the back wall surface, the efficiency of washing the back wall surface is improved, and since splashes do not occur, the urinal is easy to use. Further, in a spreader which is installed at an upper portion of the back wall surface of the urinal and has a water spray port for spraying washing water onto the back wall surface, the spreader has a structure for foam generation. Since the foam is generated and the foam is jetted to the back wall surface, it is difficult for the conventional foam to come out, and the urinal has a good use condition.
