Japanese Unexamined Patent Publication No. 2016-102366

However, in the conventional urinal as shown in Patent Document 1 described above, when the cleaning flow rate is low, the cleaning flow rate of the outer spout is also low, so that the toilet bowl is ejected with a sufficient distance in the left-right direction. There was a problem that it could not be made to do. Therefore, there is a possibility that the area in the left-right direction cannot be sufficiently cleaned, and there is room for improvement in that respect.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a spreader and a urinal capable of expanding the cleaning area of a toilet bowl by increasing the cleaning flow rate in the left-right direction.

In order to achieve the above object, the spreader according to the present invention is a spreader that is attached to the front of a toilet bowl located in front of the toilet bowl when viewed from the front in a used state and ejects washing water to the toilet bowl. It has a water spouting portion for ejecting water and a water supply channel provided behind the spouting portion to supply washing water from the outside toward the spouting portion. A water discharge wall extending to the water discharge wall is provided, and a water supply opening communicating with the water supply channel is formed in the center of the left and right sides of the water discharge wall. It is distributed to the inner water discharge channel provided in the center of the left and right and the outer water discharge channel provided on the left and right outer sides of the inner water discharge channel, and the area of the outer water discharge channel is set to be larger than the area of the inner water discharge channel. It is characterized by that.

Further, the urinal according to the present invention is a urinal in which the above-mentioned spreader is attached to the front surface of the toilet bowl, and the washing water ejected from the water discharge portion of the spreader is the stool from the inner water discharge channel. It is characterized in that it is ejected toward the lower part of the pot and is ejected from the outer drainage channel so as to spread in the left-right direction of the urinal.

According to the present invention, the area of the outer discharge channel is made larger than the area of the inner discharge channel in at least a part of the area corresponding to each of the outer discharge channel and the inner discharge channel in the water discharge portion, thereby causing the outer discharge. It is possible to increase the lateral washing flow rate by the washing water (outer washing water) ejected from the outer outlet of the water channel. Therefore, when the spreader is placed in front of the toilet bowl of the urinal, the momentum of the outer washing water is increased and it becomes difficult for it to fall down, and the ejection distance in the left-right direction becomes large. The cleaning can be performed well, and the toilet bowl can be washed over a wide area.

Further, in the urinal according to the present invention, the outer inlet area of the outer outlet is larger than the outer outlet area of the outer outlet constituting the outer outlet, and the inner outlet is the inner inlet. It is preferable that the inner inlet area is smaller than the inner outlet area of the inner spout constituting the inner outlet.

In this case, by making the outer inlet area of the outer inlet in the outer drainage channel larger than the outer outlet area of the outer spout, the flow velocity of the outer wash water is increased to extend the ejection distance, and the water is discharged to a farther position. can do. Further, by making the area of the inner inlet of the inner inlet in the inner discharge channel smaller than the area of the inner outlet of the inner spout, the flow velocity of the inner wash water can be reduced and the ejection range can be widened to discharge the water.

Further, in the spreader according to the present invention, the length dimension in the front-rear direction at the outer spout that constitutes the outer outlet of the outer spout is the length in the front-rear direction at the inner spout that constitutes the inner outlet of the inner spout. It is preferably larger than the dimensions.

In this case, by increasing the length of the outer outlet (outer spout) in the front-rear direction, that is, the depth length, the opening area can be increased without spreading the washing water too much in the left-right direction. The washing flow rate can be increased without jumping out of the toilet bowl. By increasing the washing flow rate in this way, the momentum of the water increases, and it becomes easier for the water to flow to the front wall of the toilet bowl.
That is, in the present invention, there is a problem such as when the opening size in the left-right direction is lengthened in order to increase the opening area of the outer spout, that is, the washing water ejection range is too wide to wash from the side surface of the toilet bowl. It is possible to suppress the occurrence of problems such as water splashing out.

Further, in the spreader according to the present invention, a pair of left and right inner guides for partitioning the inner water discharge channel and the outer water discharge channel are provided on the front surface of the water discharge wall, and the water supply is provided between the pair of left and right inner guides. An inflow port communicating with the opening is formed, and the inner guide extends diagonally downward from the inner inlet side of the inner drainage channel toward the inner outlet side, and the first guide portion on the inner inlet side and the inner outlet side. It may be characterized in that the second guide portion of the above extends in a different direction.

In this case, a part of the washing water supplied to the water discharge part from the water supply opening flows into the inner water discharge channel from the inner inlet formed by the inner guide, and is ejected from the inner water discharge port of the inner outlet toward the toilet bowl. Will be done. At this time, since the first guide portion is provided on the inner inlet side of the inner guide, the opening width of the inner inlet of the inner drainage channel is kept small, and the washing water supplied from the water supply opening to the discharge portion is downward from the inflow port. That is, the inflow to the inner drainage channel can be suppressed. Therefore, it can be guided to the outer drainage channel side, and the inflow amount to the outer drainage channel can be increased.
Further, by adjusting the position of the second guide portion of the inner guide, it is possible to regulate the upper edge of the spread of the washing water ejected from the inner spout.

Further, in the spreader according to the present invention, an outer guide is provided on the front surface of the water discharge wall at intervals above the inner guide, and the outer water discharge channel is provided between the inner guide and the outer guide. It is preferably a flow path to be formed.

In this case, the upper side of the washing water passing through the outer drainage channel can be guided along the outer guide. In other words, by providing an outer guide, it is possible to suppress the spread of water outside the outer spout, which is the outer outlet of the outer spout, and regulate the upper edge of the spread of the wash water ejected from the outer spout. Can be done.
As described above, in the present invention, the washing water supplied from the water supply opening to the water discharge portion directly flows from the water supply opening to the water discharge port, that is, between the water supply opening and the water discharge port, as in the case where the outer guide is not provided. Since the water flow path is such that the washing water does not flow into other parts, it is possible to prevent a decrease in the momentum of the washing water that is ejected.
Therefore, the flow from the water supply opening to the outer spout of the washing water flowing into the outer spout can be stabilized, and the decrease in the washing flow rate of the washing water ejected from the outer spout can be suppressed.

Further, in the spreader according to the present invention, it is preferable that a drip prevention guide is provided in the center of the left and right of the inner water discharge channel on the front surface of the water discharge wall.

In this case, the drip prevention guide can be provided in contact with the pottery surface of the toilet bowl, so that the water can easily flow into the toilet bowl. Therefore, after the water supply is completed, the residual water in the spreader flows to the front portion of the toilet bowl along the dripping prevention guide, so that it is possible to prevent the residual water from dripping directly on the bottom surface of the pot.

According to the spreader and the urinal of the present invention, the cleaning area of the toilet bowl can be expanded by increasing the cleaning flow rate in the left-right direction.

Hereinafter, the spreader and the urinal according to the embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 4, the urinal 1 according to the present embodiment is intended for a wall-mounted urinal that is attached along the back wall surface K so that the lowermost portion of the urinal 1 is floated from the floor surface. It is supposed to be. The urinal 1 is provided in a ceramic urinal body 10 having a toilet bowl 11, a spreader 2 for cleaning the toilet bowl 11 (see FIG. 4), and a drain port 11c provided on the bottom surface 11C of the toilet bowl 11. It is equipped with a drain trap 3 (see FIG. 4) to be connected.

Here, in the present embodiment, when the user is positioned so as to look at the urinal 1 from the front, the side closer to the user is the front side, and the far side on the opposite side is the rear side. Further, the portion connected between the front side and the rear side of the urinal 1 is defined as the side. Further, the left-right direction when the urinal 1 is viewed from the front side is referred to as a left-right direction X1, and the front and rear directions are referred to as a front-back direction X2.

The urinal body 10 has a toilet bowl 11 located on the front surface and a peripheral wall portion 12 extending rearward from the opening 13 of the toilet bowl 11. The rear end edge 10a of the urinal body 10 extends in the vertical direction when viewed from the side, and is installed in a state of being in contact with the wall surface K.

The peripheral wall portion 12 is connected to the upper surface portion 12A, a pair of left and right side surface portions (left side surface portion 12B, right side surface portion 12C) connected to the upper surface portion 12A, the left side surface portion 12B, and the right side surface portion 12C, and is connected to the lower front surface of the toilet bowl 11. It has a front surface portion 12D located at the front surface portion 12D, and a bottom surface portion 12E connected to the front surface portion 12D and the pair of side surface portions 12B and 12C. The opening 13 formed at the front end of the peripheral wall portion 12 is continuously connected to the outer peripheral edge of the toilet bowl 11. That is, the toilet bowl 11 and the peripheral wall portion 12 have an integral structure.

The upper surface portion 12A has a width in the front-rear direction X2 and extends in the left-right direction X1, and the entire surface portion 12A is curved downward from the central portion in the left-right direction X1 toward the side surface portions 12B and 12C on both the left and right sides. Further, the upper surface portion 12A is gradually inclined downward from the front side to the rear side in the front-rear direction X2 over the entire left-right direction X1. That is, at least at the uppermost portion of the urinal body 10 (the top of the upper surface portion 12A), the front side portion 12a is at a higher position than the back side portion 12b.

The front end of the left side surface portion 12B and the right side surface portion 12C located on the left and right sides is formed with a front end inclined portion 12c that gradually inclines forward from above to the bottom. Further, as shown in FIGS. 5 to 8, the left side surface portion 12B and the right side surface portion 12C gradually move from the inside to the outside in the left-right direction X1 from the front side to the rear side in the front-rear direction X2 over the entire vertical direction X3. It is tilted. That is, the left side surface portion 12B and the right side surface portion 12C are formed so as to project outward in the left-right direction X1 on the back side from the front side when viewed from the front.

Further, as shown in FIG. 7, the lower regions of the left side surface portion 12B and the right side surface portion 12C are inclined toward the front surface portion 12D while being curved so as to narrow toward the front. The radius of curvature R of the curved portion at this time is set to a relatively large curvature of, for example, R110 mm. Therefore, the urine adhering to the side surface portions 12B and 12C collects at the convex top portion of the front surface portion 12D.

As shown in FIGS. 3 and 4, the front surface portion 12D is formed so as to be inclined forward so as to be inclined forward from the bottom surface portion 12E.

The bottom surface portion 12E is continuously connected to the lower end edges of the front surface portion 12D and both side surface portions 12B and 12C. As shown in FIGS. 5, 9 to 13, the bottom surface portion 12E is formed with a bottom recessed portion 12F that is recessed upward in the central portion in a plan view seen from below.

As shown in FIGS. 4 and 5, the drain trap 3 forms a tubular flow path, and the inflow port 3a at one end is connected to the drain port 11c of the pot bottom surface 11C of the toilet bowl 11, and the outflow port 3b at the other end is connected. Is provided on the rear surface side of the urinal body 10. As shown in FIG. 11, the drain trap 3 has a substantially lower half portion arranged in the recess of the bottom recess 12F.

Specifically, the drain trap 3 includes a drainage cylinder 31 extending downward from the drainage port 11c, a curved wall 32 that folds back approximately 180 degrees from the lower end opening of the drainage cylinder 31 toward the rear of the drainage cylinder 31, and an upward portion from the curved wall 32. It has an upward wall 33 extending toward it.
The drainage cylinder 31 constitutes a blocking wall that blocks the inside of the drainage cylinder 31 and the toilet space portion 14 on the outer peripheral side so as not to communicate with each other. The above-mentioned outlet 3b is provided on the upper rear surface side of the upward wall 33. An end of a drainage pipe (not shown) provided inside the wall surface K is connected to the outlet 3b. The lower end 32a of the curved wall 32 of the drain trap 3 is located at the lowermost end 3c of the entire drain trap 3 and is located above the bottom surface portion 12E.

As shown in FIGS. 10 and 11, the bottom surface portion 12E located at the lower end edge of the bottom recess 12F is located below the lower end 3c of the drain trap 3 connected to the drain port 11c of the toilet bowl 11.
Further, as shown in FIG. 11, the rear wall of the bottom recess 12F forms a vertical wall 143 extending in the vertical direction. The outer peripheral wall of the drain trap 3 is connected from the upper end of the vertical wall 143 toward the front. The portion of the drain trap 3 facing the front side of the vertical wall 143 (upward wall 33) is gradually inclined downward so that the inclination angle with respect to the horizontal plane becomes smaller toward the front.

The inner surface of the bottom recess 12F made of pottery is covered with glaze. Since the glaze coated on the inner surface of the bottom recess 12F is smoothly finished in this way, dirt is less likely to adhere to the inner surface. In addition, the inner surface covered with the glaze is more easily cleaned, and the attached dirt can be easily removed, so that the dirt becomes less noticeable.

The urinal body 10 is formed in a hollow shape surrounded by the toilet bowl 11 and the peripheral wall portion 12, and the toilet space portion 14 surrounding the circumference of the drain trap 3 is formed.

The bottom recess 12F formed in the bottom portion 12E is partially formed in a shape along the drain trap 3.
As shown in FIG. 2, the front lower end of the bottom recess 12F is formed with a left-right convex curved surface 12e that is convex downward at the center of the left-right direction X1.

As shown in FIG. 11, the peripheral wall of the bottom recess 12F constituting the toilet space portion 14 has a rising wall 141 extending upward from the bottom surface portion 12E and an upper end of the rising wall 141 toward the outer peripheral surface of the drainage cylinder 31. A connecting wall 142 that extends and is connected at a position in the middle of the drainage cylinder 31 in the vertical direction is provided.

The connecting wall 142 corresponds to the top surface of the bottom recess 12F, and is arranged in a range in front of the position near the rear end of the drainage cylinder 31. That is, a part of the toilet space portion 14 (drainage side space 14A) is formed between the connecting wall 142 and the portion above the connecting portion of the drainage cylinder 31 with the connecting wall 142 (FIG. 13 (a)). ), (B)).

The connecting wall 142 includes a front connecting wall 142A shown in FIGS. 11 and 13B and a rear connecting wall 142B shown in FIG. 13A, and the front connecting wall 142A is below the rear connecting wall 142B. It is located at a height, and a step above and below is formed at the boundary portion of each of the front-rear directions X2. As shown in FIG. 9, the boundary portion between the connecting walls 142A and 142B in the front-rear direction X2 is located at a substantially central portion of the drainage cylinder 31 (described later) of the drain trap 3 in the front-rear direction X2.

As shown in FIGS. 10 and 11, a front-rear convex curved surface 12d that is convex downward in a side view is formed on the front portion of the bottom surface portion 12E at a position in front of the bottom recess 12F. The front-rear convex curved surface 12d is formed so as to be curved by a continuous curved surface from the front surface portion 12D toward the bottom surface portion 12E, extend upward on the rear side of the curved surface portion, and connect to the bottom recess 12F. As shown in FIG. 9, the front-rear convex curved surface 12d is curved so as to be convex to the front side over the entire left-right direction X1 in a plan view seen from below. By providing such a curved portion, the cleanability is improved. The curved surface range of the curved portion that is convex to the front side of the front-rear convex curved surface 12d is not limited to the entire left-right direction X1, and may be a shape in which the curved surface is formed only at the corner portions on both the left and right sides. However, in order to improve the cleanability, it is preferable that the radius of curvature of the curved surface of this corner is large.

As shown in FIG. 12, the toilet bowl 11 has an opening 13 that is open from the upper part to the lower part so as to face the user. The opening 13 is a pair of front end inclined portions 13a and 13a of the left side surface portion 12B and the right side surface portion 12C, and an upper front end arc portion 13b of the upper surface portion 12A connected to the upper ends of the pair of front end inclined portions 13a and 13a. A lower front end arc portion 13c of the front surface portion 12D connected to the lower ends of the front end inclined portions 13a and 13a is formed.
The pair of front end inclined portions 13a and 13a, the upper front end arc portion 13b, and the lower front end arc portion 13c are respectively located on the same plane. The pair of front end inclined portions 13a, 13a are parallel to each other. The upper front end arc portion 13b and the lower front end arc portion 13c form a single arc having substantially the same radius of curvature. The opening 13 has a vertically symmetrical shape when viewed from a direction orthogonal to the plane including the opening 13.

As shown in FIGS. 13 (a) and 13 (b), the toilet bowl 11 has a front portion 11A and a side surface portion extending forward from both left and right sides of the front portion 11A in the entire area of the vertical direction X3. It has an 11B and a pot bottom surface 11C, each of which is smoothly curved and continuously connected (see FIG. 4).

The front portion 11A extends from above to the pot bottom surface 11C along a substantially vertical direction. A through hole 11b penetrating in the front-rear direction X2 is formed in the central portion of the left-right direction X1 in the upper region 11a near the upper end of the front portion 11A. A spreader 2 is fitted in the through hole 11b.

The front surface portion 11A and the side surface portions 11B and 11B are formed with a continuous concave curved surface in a horizontal cross-sectional view so that the washing water W discharged from the spreader 2 can be guided to the pot bottom surface 11C. As shown in FIGS. 6 (a) to 6 (c) and FIG. 7, the side surface portion 11B gradually increases the amount of protrusion toward the front from the front surface portion 11A from the upper side to the lower side. That is, in the horizontal cross-sectional view, the depth of the concave portion of the toilet bowl 11 becomes deeper toward the lower side than the upper portion.

Further, the width dimension of the front portion 11A in the left-right direction X1 is smaller than the opening width of the opening 13 over the entire vertical direction X3 in the horizontal cross-sectional view.
Further, as shown in FIG. 7, the rim 11D forming the connection portion between the toilet bowl 11 and the peripheral wall portion 12 has a rimless shape, and the opening width of the rim 11D in the lower region in the toilet bowl 11 in a horizontal cross-sectional view. A portion having a width D2 larger than D1 is formed. With such a shape, it is possible to prevent the urine from bouncing to the outside of the toilet bowl 11.

As shown in FIGS. 13 (a) and 13 (b), the pair of left and right side surface portions 11B and 11B gradually become smaller in the width dimension in the left-right direction X1 from above toward the pot bottom surface 11C. The width of the left-right direction X1 becomes narrower from the front toward the front portion 11A side (rear side).
Here, in the side view shown in FIG. 3, the horizontal line passing through the intersection of the extension line P0 extending upward from the front-rear convex curved surface 12d and the front end inclined portion 12c (opening portion 13) is defined as the boundary line P, and the opening portion is defined as the boundary line P. In 13, the lower side of the boundary line P is the lower region P1, and the upper side is the upper region P2.

Further, in the present embodiment, since the urinal 1 has a low height, the first opening area S1 of the lower region P1 is larger than that of a general urinal. Here, the ratio of the first opening area S1 of the lower region P1 to the second opening area S2 of the upper region P2 is set to, for example, S1: S2 = 1: 2, and is preferably 1: 1.
With this configuration, the curved surface in front of the extension line P0 makes it easy for urine to collect on the front-back convex curved surface 12d via the front portion 12D, as shown by the arrows S in FIGS. 1 and 3. There is an advantage that urine can be easily transmitted to the front-back convex curved surface 12d.

As shown in FIG. 4, on the pair of left and right side surface portions 11B and 11B, the washing shelves 15 extend downward from the rear to the front at each position symmetrical in the height direction of the toilet bowl 11. It is provided. In this case, since the urinal 1 is discharged from the spreader 2 and the washing water W on the pair of left and right washing shelves 15 is guided to the pot bottom surface 11C in front of the lower part of the toilet bowl 11, the lower front part of the toilet bowl 11 is washed. can do.
Further, since the washing shelf 15 is located below the tip of the front surface portion 12D, the design is good.

As shown in FIGS. 4 and 11, a bowl-shaped drainage port 11c extending upward is provided on the rear side of the pot bottom surface 11C. A perforated plate 4 (see FIG. 4) is arranged at the drainage port 11c. Further, the upper end of the drain trap 3 arranged in the toilet space 14 (described later) below the bottom surface 11C of the pot is connected to the drain port 11c.

The bottom surface 11C of the pot is gently inclined toward the drain port 11c so that the drainage collects at the drain port 11c. Further, the pot bottom surface 11C has a track shape in which a pair of substantially straight lines extending in the front-rear direction X2 and the front ends and rear ends of the straight lines are connected by curves in a curved line. Since the pot bottom surface 11C may have a shape that does not spread toward the front side, the straight line portion described above does not have to be a straight line extending in the front-rear direction X2.
In this way, an inclined surface is formed on the bottom surface 11C of the pot, and the cross-sectional area of the plane around the center (the position where urine hits well) is small, so that the urine that hits this inclined surface is hard to bounce outward. ..
On the other hand, for example, if the shape of the bottom surface of the pot is widened on the front side, the flat surface portion on the front side becomes wide, the curved surface connecting the side surface portion and the front surface portion becomes small, and the flow velocity of the pre-purified water decreases at the curved surface portion, and the pot first. Since it easily falls on the bottom surface, it becomes difficult to clean the front portion 12D side. In the present embodiment, as described above, the pot bottom surface 11C has a shape that does not spread toward the front side, so that a decrease in the flow velocity of the washing water can be suppressed.

As shown in FIG. 4, the perforated plate 4 has a disk shape and is arranged in a state where the central axis of the disk shape is oriented in the vertical direction X3, and the outer diameter is formed to be slightly smaller than the inner diameter of the drain port 11c. .. In the perforated plate 4, the disk-shaped outer peripheral surface does not come into contact with the inner peripheral surface of the drainage port 11c, and a predetermined distance is provided between the disk-shaped outer peripheral surface and the inner peripheral surface of the drainage port 11c. Have been placed.

Next, the configuration of the spreader 2 will be described in detail with reference to the drawings.
As shown in FIGS. 13 (a) and 13 (b), the spreader 2 is provided substantially in the left and right center of the upper region 11a of the front portion 11A of the toilet bowl 11, and the washing water W is left and right from the central region U1 of the toilet bowl 11. Spout water so that it extends to the end. As shown in FIGS. 14 and 15, the spreader 2 has a built-in ultrasonic sensor 21 that ejects the washing water W and detects that the user stands in front of the urinal 1 and moves away from it. An ultrasonic sensor 21 is a device that detects a user by transmitting ultrasonic waves to a user who is an object by a transmitter and receiving the reflected waves by a receiver. In the present embodiment, it is assumed that the transmitter and the receiver are integrally installed in the sensor head of the ultrasonic sensor 21.

As shown in FIG. 16, the spreader 2 has an outer cylinder portion 20 and a partition wall 22 that is vertically and liquidally partitioned in the outer cylinder portion 20 at a substantially central portion in the vertical direction X3, and is shown in FIG. 13 (a). ), (B), the central axis is provided on the front portion 11A of the toilet bowl 11 with the central axis facing the front-rear direction X2. The spreader 2 has an electrical path 23 on the upper side of the partition wall 22 for accommodating wiring for transmitting and receiving an electric signal to the ultrasonic sensor 21 described above, and a water supply path for ejecting wash water W on the lower side of the partition wall 22. It has a 24 and a ridged tubular cover body 25 that fits the tip of the outer cylinder portion 20 from the outside and covers the tip of the electrical passage 23 and the water supply passage 24.

Since the electrical path 23 is liquid-tightly partitioned from the water supply path 24 by a partition wall 22, the washing water W passing through the water supply path 24 is an electrical device such as an ultrasonic sensor 21 inside the electrical path 23. It is a structure that does not take up.
The ultrasonic sensor 21 has a cylindrical shape and is arranged at the tip of the electrical path 23 via an elastic body 2a such as silicon rubber. The ultrasonic sensor 21 is provided so that the ultrasonic irradiation angle and the angle range can be arbitrarily set according to the distance and height from the object. An opening is formed in the cover body 25 so that the ultrasonic sensor 21 is exposed.

At the front end of the water supply channel 24, a water discharge portion 26 for ejecting the washing water W into the toilet bowl 11 of the urinal 1 is provided. The water supply channel 24 is a flow path for supplying the washing water W from the outside toward the water discharge unit 26.
As shown in FIG. 17, the water discharge portion 26 is provided with the wall surface facing the front surface so as to be substantially orthogonal to the plane of the partition wall 22, and the water discharge wall is formed with a water supply opening 261b communicating with the water supply channel 24. Has 261. The water supply opening 261b is arranged at the center of the water discharge wall 261 in the left-right direction X1 and above the partition wall 22. The water discharge wall 261 gradually inclines toward the pot surface side of the toilet bowl 11 with an inclination angle of about 10 ° from the front to the rear as it goes downward, so that the washing water W can easily flow along the pot surface. ing.

The water discharge unit 26 is arranged on the left and right sides of the inner water discharge passage 26A for discharging the washing water W toward the substantially central region U1 (see FIGS. 13 (a) and 13 (b)) of the toilet bowl 11 and the inner water discharge passage 26A. An outer water discharge passage 26B is provided so as to spread the wash water W over a wide range of left and right regions U2 from the substantially central region U1 of the toilet bowl 11 (see FIG. 18). As a result, the washing water W supplied from the water supply opening 261b to the water discharge portion 26 is distributed to the inner discharge passage 26A and the outer discharge passage 26B by the inner guide 262.

The inner guide 262 is a member that separates the inner water discharge channel 26A and the outer water discharge channel 26B, and is a front surface of the water discharge wall 261 at positions on both the left and right sides spaced apart from each other in the left-right direction X1 below the water supply opening 261b. It is provided in. That is, inflow ports communicating with the water supply opening 261b are formed in the left and right centers of the inner guides 262 and 262 on both the left and right sides.

The pair of inner guides 262 and 262 have a shape extending diagonally downward from the inner inlet (inner inflow port 262b) side to the inner outlet (inner spout 262a) side in the inner water discharge channel 26A, respectively. Specifically, in the inner guide 262, the horizontal guide portion 262A (first guide portion) on the inner inflow port 262b side and the inclined guide portion 262B (second guide portion) on the inner spout 262a side are directed in different directions. It is postponed. The horizontal guide portion 262A extends in the horizontal direction from the position where the above-mentioned inflow port 26a is secured. The inclined guide portion 262B extends diagonally downward from the end portion of the horizontal guide portion 262A opposite to the inflow port 26a. Between the horizontal guide portions 262A and 262A, a pair of inner inflow ports 262b and 262b are formed between the horizontal guide portions 262A and the dripping prevention guide 263, which will be described later, respectively. A pair of inner spouts 262a and 262a are formed between the lower ends of the pair of inclined guide portions 262B and the lower ends of the pair of inclined guide portions 262B, respectively, with the drip prevention guide 263 described later. The inner drainage channel 26A is a region below the inner guide 262. The inner guide 262 regulates the upper edge of the spread of the inner wash water W1 ejected through the inner drainage channel 26A.

The inner drainage channel 26A is arranged at the center of the left and right between the pair of inclined guide portions 262B and 262B, and is provided with a drip prevention guide 263 so as to divide the inner drainage channel 26A to the left and right.

Further, the water discharge portion 26 is provided with outer guides 264 at intervals above the pair of inner guides 262 and 262. The outer guide 264 is provided on the front surface of the water discharge wall 261 and is formed symmetrically with respect to the upper end portion of the water supply opening 261b, and one side thereof extends diagonally downward to the outer peripheral edge 261a of the water discharge wall 261. There is. That is, the area below the outer guide 264 in the water discharge wall 261 is substantially fan-shaped.

The outer drainage channel 26B is a flow path formed between the inner guide 262 and the outer guide 264. An outer spout 264a is formed between the outer end portion 262c of the inclined guide portion 262B of the inner guide 262 and the outer end portion 264c of the outer guide 264 on one side of the left and right sides of the water supply opening 261b. The outer guide 264 regulates the upper edge of the spread of the outer wash water W2 ejected through the outer drainage channel 26B.

The outer drainage channel 26B is located on both the left and right sides of the inner drainage channel 26A. That is, the second ejection angle of the outer washing water W2 ejected from the outer spout 264a through the outer spout 26B is the inner washing water W1 ejected from the inner spout 262a through the inner spout 26A. It is wider than the first ejection angle.

Further, in the spreader 2 of the present embodiment, the outer inlet area N2 of the outer inlet (outer inflow port 264b) formed in the outer discharge channel is set to be larger than the inner inlet area M2 of the inner inflow port 262b.
Further, in the outer water discharge passage 26B, the outer inlet area N2 is set to be larger than the outer outlet area N1 of the outer water discharge port 264a constituting the outer outlet. In addition, the inner spout area 26A is set so that the inner inlet area M2 is smaller than the inner outlet area M1 of the inner spout 262a.

In the spreader 2 of the present embodiment, as shown in FIG. 18, the length dimension V2 in the front-rear direction X2 at the outer spout 264a of the outer spout 26B is larger than the length dimension V1 in the front-rear direction X2 at the inner spout 262a. It is set to be large.
The length dimension of each of the outer spout port 264a and the inner spout port 262a in the front-rear direction X2 is not limited to this embodiment, and each is set to the same length dimension in the front-rear direction X2. It doesn't matter if there is one.

In the spreader 2 configured in this way, as shown in FIGS. 13 (a) and 13 (b), when the user stands in front of the urinal 1, the ultrasonic sensor 21 (FIGS. 14 and 15) holds the human body. The wash water W is ejected from the water discharge unit 26 to the toilet bowl 11 of the urinal 1 by the detection signal. Then, when the user finishes the urine and moves away from the urinal 1, a detection signal detected by the ultrasonic sensor 21 is output, and the washing water W is ejected from the water discharge unit 26 to the urinal 11 to the urinal 11. To wash.
Further, since the spreader 2 having the ultrasonic sensor 21 is installed on the front portion 11A of the toilet bowl 11, the ultrasonic waves of the ultrasonic sensor 21 do not physically interfere with each other, and false detection due to mutual interference does not occur. ..
Then, in the spreader 2, it is possible to form a water curtain that extends to the vicinity of both left and right ends.

As shown in FIG. 16, when the washing water W is specifically ejected in the spreader 2, the washing water W supplied from the water supply pipe (not shown) passes through the water supply channel 24 of the spreader 2 and is discharged from the water supply opening 261b. It is supplied to 26. Then, as shown in FIG. 17, the washing water W supplied to the water discharge portion 26 from the water supply opening 261b is distributed to the inner discharge passage 26A and the outer discharge passage 26B by the inner guide 262. Washing water W is ejected to the toilet bowl 11 from the inner spout 262a and the outer spouts 264a and 264a on both the left and right sides thereof, respectively. Here, in FIGS. 13 (a) and 13 (b), the flows of the washing waters W1 and W2 discharged from the water discharge unit 26 and spread to the vicinity of the left and right end portions are shown.

The inner wash water W1 ejected downward from the inner spout 262a is discharged toward the central region U1 of the toilet bowl 11.
The outer washing water W2 ejected from the outer spout 264a in the left-right direction is diffused into the left-right region U2 so as to spread over a wider area than the central region U1, and a part of the water is discharged to the washing shelf 15 (see FIG. 4). It gets on and is guided to the front of the lower part and flows down to the bottom of the pot 11C.
Then, the ejected washing waters W1 and W2 flow toward the pot bottom surface 11C of the toilet bowl 11 and can be washed over a wide range over the central region U1 and the left and right regions U2 of the toilet bowl 11.

In this way, the washing water W discharged from the water discharge portion 26 of the spreader 2 flows radially from the spreader 2 so as to spread widely so as not to form a portion that cannot be washed on the surface of the toilet bowl 11, and the toilet bowl 11 is used. The entire stool bowl 11 can be satisfactorily washed while flowing down.
The washing water W that has flowed to the bottom surface 11C of the pot passes through the drain trap 3 from the drain port 11c and is drained.

Next, the operation of the spreader 2 and the urinal 1 according to the present embodiment will be described.
In the spreader 2 and the urinal 1 of the present embodiment, as shown in FIGS. 17 and 18, the outer inlet area N2 of the outer spout 264a of the outer spout 26B in the spout 26 is formed in the inner spout 26A. By making it larger than the inner inlet area M2 of the inflow port 262b, it is possible to increase the lateral cleaning flow rate by the outer cleaning water W2 ejected from the outer discharge port 264a of the outer discharge channel 26B.
Therefore, as shown in FIGS. 13 (a) and 13 (b), in a state where the spreader 2 is arranged on the front portion 11A of the toilet bowl 11 of the urinal 1, the momentum of the outer washing water W2 is increased and falls downward. Since it becomes difficult and the ejection distance in the left-right direction X1 becomes large, the side surface portions 11B and 11B of the toilet bowl 11 can be washed well, and the toilet bowl 11 can be washed over a wide range.

Further, in the present embodiment, as shown in FIG. 17, by making the outer inlet area N2 of the outer spout 264a larger than the outer outlet area N1, the flow velocity of the outer washing water W2 is increased and the ejection distance is extended. , Can spout water to a farther position. Further, by making the inner inlet area M2 of the inner spout 262a smaller than the inner outlet area M1, the flow velocity of the inner wash water W1 can be reduced and the ejection range can be widened to discharge water.

Further, in the present embodiment, as shown in FIG. 18, by increasing the length of the outer spout port 264a in the front-rear direction X2, that is, the depth length, the outer washing water W2 is opened without being too widened in the left-right direction X1. The area can be increased, which can increase the washing flow rate without jumping out of the toilet bowl. By increasing the washing flow rate in this way, the momentum of the water increases, so that the water can easily flow to the front wall of the toilet bowl 11 .
That is, in the present embodiment, there is a problem such as when the opening dimension of the lateral spout 264a is increased in order to increase the opening area of the outer spout 264a, that is, the ejection range of the washing water W is too wide, and the toilet bowl is used. It is possible to suppress the problem that the washing water W jumps out from the side surface of the eleven.

Further, in the present embodiment, as shown in FIG. 17, a part of the washing water W supplied to the water discharge portion 26 from the water supply opening 261b is transferred from the inner inflow port 262b formed by the inner guide 262 to the inner discharge channel 26A. It flows in and is ejected from the inner spout 262a toward the toilet bowl 11. At this time, since the horizontal guide portion 262A is provided on the inner inflow port 262b side of the inner guide 262, the opening width of the inner inflow port 262b is suppressed to a small size, and the washing water W supplied from the water supply opening 261b to the water discharge portion 26 can be discharged. The inflow from the inflow port to the lower side, that is, to the inner water discharge channel 26A can be suppressed. Therefore, it can be guided to the outer drainage channel 26B side, and the inflow amount to the outer drainage channel 26B can be increased.
Further, by adjusting the position of the second guide portion 262B of the inner guide 262, it is possible to regulate the upper edge of the spread of the inner washing water W1 ejected from the inner spout 262a.

Further, in the case of the present embodiment, the upper side of the washing water W passing through the outer drainage channel 26B can be guided along the outer guide 264. That is, by providing the outer guide 264, it is possible to suppress the spread of water outside the outer spout 264a of the outer spout 26B, and the upper edge of the spread of the outer wash water W2 ejected from the outer spout 264a is restricted. can do.
As described above, in the present embodiment, the washing water W supplied from the water supply opening 261b to the water discharge unit 26 directly flows from the water supply opening 261b to the outer water discharge port 264a, as in the case where the outer guide 264 is not provided. The washing water W does not flow into the other portion (the portion of the water discharge portion 26 in the left-right direction X1 (the upper portion of the outer guide 264 on the front surface of the water discharge wall 261 in FIG. 17)) between the water supply opening 261b and the outer water discharge port 264a. Since it is a water passage route, it is possible to prevent a decrease in the momentum of the washed water W to be ejected.
Therefore, the flow from the water supply opening 261b to the outer water discharge port 264a in the wash water W flowing into the outer water discharge channel 26B can be stabilized, and the decrease in the wash flow rate of the outer wash water W2 ejected from the outer water discharge port 264a can be suppressed. Can be done.

Further, in the present embodiment, since the drip prevention guide 263 is provided at the left and right center of the inner spout passage 26A on the front surface of the spout wall 261, the drip prevention guide 263 is provided in contact with the pottery surface of the toilet bowl 11. And it becomes easier to flow into the toilet bowl 11. Therefore, after the water supply is completed, the residual water in the spreader 2 flows through the dripping prevention guide 263 to the front portion of the stool bowl 11, so that it is possible to prevent the residual water from dripping directly onto the pot bottom surface 11C.

As described above, according to the urinal 1 of the present embodiment, the cleaning area of the toilet bowl 11 can be expanded by increasing the cleaning flow rate in the left-right direction.

Further, in the present embodiment, the inner guide 262, the outer guide 264, and the drip prevention guide 263 are provided, but such guides 262, 263, and 264 can be omitted. For example, the inner discharge passage 26A and the outer discharge passage 26B are not limited to the flow path formed by the inner guide 262 and the outer guide 264, and may have other configurations.

The shapes, positions, and the like of the inner guide 262, the outer guide 264, and the drip prevention guide 263 can also be changed as appropriate. For example, in the present embodiment, the inner guide portion 262 has a horizontal guide portion 262A and an inclined guide portion 262B, but the present invention is not limited to this, and the extending direction of the horizontal guide portion 262A is horizontal. A gentle downward slope may be formed in a direction away from the inner inflow port 262b rather than in the direction.
Further, as the shape of the inner guide 262, it extends diagonally downward from the inner inflow port 262b side in the inner spout 26A toward the inner spout 262a side, and extends diagonally downward toward the inner spout 262a side, and is located on the first guide portion and the inner spout 262a side on the inner spout 262b side. It suffices if the second guide portion extends in a different direction, and for example, the entire guide may have a curved shape.

Furthermore, the inner guide 262 and the outer guide 264 may be arranged on the cover body 25 side provided on the front surface of the spreader 2. In this case, the spreader 2 itself can be shared even if the size of the pottery of the urinal body 10 is changed. Moreover, the amount of water discharged and the ratio of the flow velocity can be changed only by changing the cover body 25 of the spreader 2 to one in which the inner guide 262 and the outer guide 264 have different positions and shapes.

Further, in the present embodiment, the washing shelves 15 are provided on the side surface portions 11B and 11B of the toilet bowl 11, but the urinal may not be provided with the washing shelves 15.
