  Patent Document 1 discloses a conventional urinal spreader. This urinal spreader has an inlet for flush water, a spout for flushing the flush water flowing from the inlet toward the toilet bowl surface of the urinal, and a conduit for communicating the inlet and the spout. I have. In addition, this urinal spreader is provided with a protruding guide for guiding cleaning water to both ends of the water outlet in the water conduit. For this reason, this spreader for urinals can wash | clean washing water also from the both ends of a spout, and can wash | clean the wide range of a toilet bowl surface.

Japanese Patent No. 4304475

  However, in the urinal spreader of Patent Document 1, if the flow rate of the wash water flowing into the inlet (the amount of water flowing per unit time: the same applies hereinafter) is increased, the flow rate of the wash water flowing out from the spout becomes stronger. For this reason, the washing | cleaning range becomes wide. Further, if the flow rate of the cleaning water flowing into the inflow port is small, the water flow of the cleaning water flowing out from the water outlet becomes weak. In particular, since it becomes difficult for the washing water to flow out from both ends of the water outlet, the washing range becomes narrow. As described above, in the urinal spreader, since the washing range greatly affects the flow rate of the wash water flowing into the inflow port, the desired wash range is washed evenly depending on the flow rate of the wash water flowing into the inflow port. There is a risk that it will not be possible. Further, in the urinal spreader, when the flow of the cleaning water is disturbed by the protruding guide and flows out from the water outlet, there is a possibility that the cleaning water splashes.

  This invention is made | formed in view of the said conventional situation, Comprising: It is the problem which should be solved to provide the spreader for urinals which can wash | clean a toilet bowl surface favorably.

The spreader for urinals according to the present invention includes an inflow port through which wash water flows, a water discharge port through which the wash water flowing in from the inflow port flows out toward the toilet bowl surface of the urinal, and the inflow port and the water discharge port communicate with each other. A urinal spreader having a water conduit,
An internal inlet through which the wash water flowing in the water conduit is opened,
An internal water conduit that is continuous with the internal inflow port and guides the wash water flowing in from the internal inflow port so as to flow out from a part of the water outlet ;
In the state attached to the urinal, the spout extends and opens in a direction along the toilet bowl surface of the urinal,
The internal water conduit is formed by left and right walls provided side by side in the extending direction of the water outlet .

  This urinal spreader adjusts the opening area of the internal inflow port, so that the flow rate of the wash water flowing out from a part of the water discharge port through the internal water conduit and the outlet of the water outlet without passing through the internal water conduit The balance with the flow rate of the wash water flowing out from other parts can be adjusted. That is, when the opening area of the internal inlet is reduced, the flow rate of the wash water flowing out from a part of the water outlet through the internal water conduit is reduced, and the flow rate of the wash water flowing out from the other part is increased. In addition, when the opening area of the internal inlet is increased, the flow rate of the wash water flowing out from a part of the water outlet through the internal water conduit is increased, and the flow rate of the wash water flowing out from the other part is decreased. For this reason, this urinal spreader adjusts the opening area of the internal inflow port, so that the state of the wash water flowing out from the spout (washing range) can be adjusted regardless of the flow rate of the wash water flowing into the inflow port. Can be adjusted. Therefore, this urinal spreader can be applied to various types of urinals having different stool surface areas. Moreover, the flow of the wash water is rectified by passing through the internal water conduit, and the splash of the wash water flowing out from the water outlet can be suppressed.

  Therefore, the urinal spreader of the present invention can clean the toilet bowl surface well.

  A preferred embodiment of the present invention will be described.

  In the urinal spreader of the present invention, the internal water conduit can reduce the flow channel area toward the upstream side. In this case, the opening area of the internal inlet can be easily changed by cutting the tip of the internal water conduit. Accordingly, since the flow rate of the washing water passing through the internal water conduit can be easily changed, the urinal spreader can easily change the washing range.

The spreader for urinals of the present invention includes an inflow pipe portion that is continuous with the inflow port and that constitutes an upstream side of the water conduit, and a peripheral wall portion on the downstream side of the water conduit that is continuously downstream of the inflow pipe portion. A side wall part that constitutes a part, and an inner wall that is continuous with the inner surface of the side wall part and includes the left and right wall parts to constitute a part of the internal inlet and a part of the peripheral wall part of the internal water conduit A spreader body having a portion, and a cover member that is attached to the side wall portion and forms the downstream side of the water conduit with the side wall portion, and that forms the internal inlet and the internal water conduit with the inner wall portion. Can be prepared. In this case, the number of parts can be reduced, and the urinal spreader can be easily assembled.

Urinal spreader of the present invention, the washing water having passed through the internal water conduit can flow out from the central portion of the extending direction of the spout. In this case, by changing the opening area of the internal inlet, the balance between the flow rate of the wash water flowing out from the central portion of the spout and the flow rate of the wash water flowing out from both ends in the extending direction of the spout is adjusted. be able to. That is, when the opening area of the internal inlet is reduced, the flow rate of the wash water flowing out from the central portion of the water discharge port decreases, and the flow rate of the wash water flowing out from both ends in the extending direction of the water discharge port increases. For this reason, this spreader for urinals increases the spread of the washing water flowing out in the extending direction of the water discharge port, and can widen the washing range. On the other hand, when the opening area of the internal inlet is increased, the flow rate of the wash water flowing out from the central portion of the water discharge port increases, and the flow rate of the wash water flowing out from both ends in the extending direction of the water discharge port decreases. For this reason, this spreader for urinals reduces the spread of the washing water flowing out in the extending direction of the water discharge port, and can narrow the washing range.

Urinal spreader of the present invention, the amount of water per unit of the washing water time flowing from the water discharge port than said central portion of the extending direction of the spout may increase the both end portions of the extending direction. In this case, the spread of the washing water flowing out to the toilet bowl surface becomes large, and the washing range can be widened.

  Next, an embodiment in which the urinal spreader of the present invention is embodied will be described with reference to the drawings.

<Example>
The urinal spreader of an Example is attached to the upper part of the toilet bowl surface 2 of the urinal 1 as shown in FIGS. As shown in FIGS. 4 and 5, the urinal spreader includes an inlet 10, a water outlet 20, and a water conduit 30. The downstream end of the upstream water supply pipe 3 is inserted into the inflow port 10, and the cleaning water flows in. The spout 20 discharges wash water toward the toilet bowl surface 2 of the urinal 1. The water conduit 30 communicates the inlet 10 and the water outlet 20. In the water conduit 30, the inflow pipe portion 11 continuing to the inflow port 10 constitutes the upstream side. Moreover, the water conduit 30 continues to the downstream end portion of the inflow pipe portion 11, and the water discharge main body portion 12 having the water discharge port 20 constitutes the downstream side. That is, the urinal spreader includes the inflow pipe portion 11 and the water discharge main body portion 12.

  As shown in FIG. 6, the inflow pipe portion 11 has a substantially cylindrical shape. When the urinal spreader is attached to the urinal 1 installed in use, the inflow pipe portion 11 is formed by two parallel flat portions 11A extending in the vertical direction at two locations located on the left and right sides of the outer peripheral surface. Yes. The inflow pipe portion 11 is threaded on the outer peripheral surface from the upstream end to the intermediate position. As shown in FIGS. 2 and 3, the inflow pipe portion 11 is inserted into the attachment hole 4 penetrating in the vertical direction of the urinal 1 installed in use, and is fastened and fixed by the nut 5. In this way, the urinal spreader is attached to the upper part of the toilet bowl surface 2.

  As shown in FIG. 5, the water discharge main body 12 has an outer shape when the central axis direction of the inflow pipe portion 11 is viewed from the side opposite to the inflow port 10 of the inflow pipe portion 11, and each corner has an arc shape. It is formed in an isosceles triangle shape. As shown in FIG. 4, the peripheral wall portion constituting the water discharge main body portion 12 is formed by a side wall portion 41 continuous with the downstream end portion of the inflow pipe portion 11 and a cover member 42 attached to the side wall portion 41. The side wall 41 gradually flows in toward a portion corresponding to the bottom of a substantially isosceles triangle shape, and a flat plate-like ceiling 41A continuous to the downstream end of the inflow pipe 11 and the ceiling 41A. A drooping portion 41B that is curved in the opposite direction to the tube portion 11 is provided. The hanging part 41B of the side wall part 41 forms an outer side surface 43 facing the toilet bowl surface 2 extending in the vertical direction of the urinal 1 installed in use. The side wall 41 constitutes a part of the peripheral wall on the downstream side of the water conduit 30. The inflow pipe portion 11 is connected to the ceiling portion 41 </ b> A of the side wall portion 41 near the portion 12 </ b> T corresponding to the apex angle of the substantially isosceles triangle of the water discharge main body portion 12.

  As shown in FIG. 5, the cover member 42 has a substantially isosceles triangular shape whose outer shape is substantially equal to the outer shape of the side wall portion 41. An edge portion 42A corresponding to two equilateral sides extending from a portion corresponding to the apex angle of the substantially isosceles triangle shape of the cover member 42 extends from a portion corresponding to the apex angle of the substantially isosceles triangle shape of the side wall portion 41. It is connected to an edge 41A corresponding to two equal sides in a watertight manner. The cover member 42 swells in a curved shape so as to form the water conduit 30 and the internal water conduit 50 with the side wall portion 41. That is, the cover member 42 constitutes the downstream side of the water conduit 30 together with the side wall portion 41. The water discharge main body 12 includes an edge portion 42B corresponding to the base of the substantially isosceles triangle shape of the cover member 42, and an edge portion 41B provided at a portion corresponding to the base of the approximately isosceles triangle shape of the side wall portion 41. A slit-like opening having an equal interval is formed. This opening constitutes the water outlet 20. In a state where the urinal spreader is attached to the urinal 1, the spout 20 extends laterally along the toilet bowl surface 2 of the urinal 1 and opens.

  This urinal spreader is in the water discharge main body portion 12, and is continuous with the internal inlet 51 and the internal inlet 51 into which the wash water that flows into the downstream water conduit 30 and flows through the water conduit 30 flows. An internal water conduit 50 that guides the wash water flowing in from the internal inflow port 51 so as to flow out from the left and right central portions of the water discharge port 20 is provided.

  The water discharge main body portion 12 has an inner wall portion 60 extending from the left and right central portion of the inner surface of the hanging portion 41B of the side wall portion 41 toward the vicinity of the opening of the downstream end portion of the inflow pipe portion 11. The distal end portion 60A of the inner wall portion 60 extends to a position where the cleaning water flowing into the water discharge main body portion 12 directly collides from the inflow pipe portion 11. The inner wall portion 60 has a urinal spreader attached to the urinal 1 installed in use, and a central wall portion 61 that curves downward toward the left and right central portions, and an obliquely downward outer side from both sides of the central wall portion 61. The left and right wall portions 62 are inclined toward the left side. Further, the inner wall portion 60 is formed with a single reinforcing rib 63 extending from the inner surface of the hanging portion 41 </ b> B of the side wall portion 41 to the front end portion 60 </ b> A of the inner wall portion 60 on the lower left and right center lower surfaces of the central wall portion 61.

  The lower end surfaces of the left and right wall portions 62 of the inner wall portion 60 and the lower end surfaces of the reinforcing ribs 63 are in contact with the inner surface of the cover member 42 attached to the side wall portion 41 of the water discharge main body portion 12. Thus, two internal water conduits 50 are formed between the central wall 61 of the inner wall portion 60 and the cover member 42 and between the left and right wall portions 62 and the reinforcing rib 63. In addition, an internal inflow port 51 is formed on the upstream side of the two internal water conduits 50 by the front end portion 60 </ b> A of the inner wall portion 60 and the cover member 42. That is, the inner wall part 60 constitutes a part of the internal inlet 51 and a part of the peripheral wall part of the internal water conduit 50. For this reason, the wash water that has flowed in from the internal inflow port 51 passes through the internal water conduit 50 and flows out from the left and right central portions of the water outlet 20. As shown in FIGS. 6 to 9, the internal water conduit 50 has an interval between the cover member 42 and the central wall portion 61 that narrows toward the upstream side, and each of the left and right wall portions 62 and the reinforcing rib 63. Since the interval is also narrowed, the flow channel area is reduced toward the upstream side.

  As shown in FIG. 5, the water discharge main body 12 has ribs 64 extending from the respective inner surfaces of the left and right ends of the hanging part 41 </ b> B of the side wall 41 toward the inflow pipe 11. These ribs 64 guide cleaning water other than the cleaning water flowing into the internal water conduit 50 from the internal inflow port 51 to the left and right ends of the water discharge port 20 among the cleaning water flowing into the water conduit 30 from the inflow port 10.

  As described above, the urinal spreader includes the spreader body 70 having the inflow pipe portion 11, the side wall portion 41, and the inner wall portion 60, and the cover member 42. For this reason, the spreader for urinals has few parts and can be assembled easily.

  Moreover, the spreader for urinals has the two convex parts 80 which protruded toward the toilet bowl surface 2 in the outer surface 43 of the water discharging main-body part 12, as shown in FIG. These convex portions 80 are cylindrical, and are separated from the left and right ends (both ends positioned in the vertical direction in FIG. 10) of the outer surface 43, that is, left and right (up and down in FIG. 10) with respect to the inflow pipe portion 11. One is provided at each position.

  When one of the convex portions 80 is inserted into the mounting hole 4 of the urinal 1 through the inflow pipe portion 11 and is fastened and fixed by the nut 5, the water discharge main body portion 12 rotates in the tightening direction so that the toilet bowl surface is rotated. 2 is provided at one end (upper end in FIG. 10) of the outer surface 43 approaching 2. For this reason, when the convex part 80 contact | abuts on the toilet bowl surface 2, it can prevent that the water discharging main-body part 12 rotates further. As described above, when the urinal spreader is attached to the urinal 1 or the like made of earthenware by allowing a slight gap to be generated between the spout 20 and the toilet bowl surface 2, By contacting the toilet bowl surface 2 of the urinal 1, the urinal spreader can be attached to an appropriate position. That is, the urinal spreader can be attached in a state where the gap is substantially uniform between the spout 20 and the toilet bowl surface 2. For this reason, the wash water that has flowed out from the spout 20 can flow well on the toilet bowl surface 2.

  Moreover, since the convex part 80 was provided in the left-right both ends of the outer side surface 43, ie, the position which left | separated right and left with respect to the inflow pipe part 11, respectively, the water discharge main-body part 12 centered on the inflow pipe part 11. The clockwise and counterclockwise rotations can be restricted. Also by this, the spreader for urinals can be attached in a state where the gap is substantially uniform between the spout 20 and the toilet bowl surface 2. For this reason, the wash water that has flowed out from the spout 20 can flow well on the toilet bowl surface 2.

  Moreover, the convex part 80 is formed with a curved corner. For this reason, when the convex part 80 contact | abuts on the toilet bowl surface 2, it can prevent that the corner | angular part of the convex part 80 is missing, or the toilet bowl surface 2 is damaged by the convex part 80.

  As shown in FIGS. 4 to 9, in the urinal spreader having such a configuration, when washing water flows from the inlet 10, the opening area of the inner inlet 51 is small, so that the washing flowing into the inner water conduit 50 is washed. It is possible to reduce the flow rate of the cleaning water that passes through the internal water conduit 50 and flows out from the left and right central portions of the water outlet 20 while suppressing the flow rate of water. On the other hand, the flow rate of the cleaning water that passes through the water conduit 30 other than the cleaning water that passes through the internal water conduit 50 increases. For this reason, the flow volume of the washing water flowing out from the left and right ends of the water discharge port 20 is increased, the spreading of the washing water flowing out from the toilet bowl surface 2 in the left-right direction is increased, and the washing range can be widened.

  Further, as shown in FIGS. 11 and 12, the urinal spreader cuts the front end portion 60 </ b> A of the inner wall portion 60 to shorten the length of the internal water conduit 50 and increase the opening area of the internal inflow port 51. It can be easily enlarged. If it does in this way, the flow volume of the wash water which flows into the internal water conduit 50 will increase, and the flow volume of the wash water which passes through the internal water conduit 50 and flows out from the right and left central part of the spout 20 can be increased. On the other hand, the flow rate of the wash water that passes through the water conduit 30 other than the wash water that passes through the internal conduit 50 is reduced. For this reason, the flow rate of the washing water flowing out from the left and right ends of the water discharge port 20 is reduced. For this reason, the flow rate of the wash water flowing out from the left and right ends of the spout 20 is reduced, the spread of the wash water flowing out of the toilet bowl surface 2 in the left-right direction can be suppressed, and the washing range can be narrowed.

  Thus, this urinal spreader adjusts the opening area of the internal inlet 51 by cutting the front end portion 60A of the inner wall portion 60, regardless of the flow rate of the washing water flowing into the inlet 10. The state (cleaning range) of the cleaning water flowing out from the water outlet 20 can be adjusted. Moreover, this urinal spreader can change the washing | cleaning range, without changing an external appearance. Therefore, this urinal spreader can be applied to various types of urinals 1 having different stool surface 2 areas. Further, the flow of the cleaning water is rectified by passing through the internal water conduit 50, and the splashing of the cleaning water flowing out from the water outlet 20 can be suppressed.

  Therefore, the urinal spreader of the embodiment can clean the toilet bowl surface 2 satisfactorily.
