Description

The present invention relates to a toilet spouting component that is attached to a flush toilet bowl, a toilet bowl equipped with this spouting component, and a toilet bowl assembly.

There are simple flushing temporary toilets that can be transported and installed at construction sites, outdoor event venues, disaster evacuation shelters, etc. In such temporary Western-style toilets, flushing water is discharged onto the surface of the toilet bowl from two locations, for example, one at the rear of the seat, and one at the rear and front of the seat (see, for example, Patent Document 1).

On the other hand, in Western-style toilets that are permanent rather than temporary, there are configurations in which a water supply path is formed in the toilet body along the periphery of the toilet bowl under the toilet seat, and water flows from multiple water discharge holes drilled in the water supply path onto the bowl surface, or water is discharged in a spiral (swirling water) onto the bowl surface from a water flow channel provided in the water supply path that is inclined downward from the bowl, making it possible to have water flow over the entire surface of the bowl (for example, Patent Document 2).

Utility Model Publication No. 59-076677 JP 2005-307650 A

By flushing water over the entire surface of the toilet bowl, as in the permanent toilet described above, the problem of waste remaining on the surface of the bowl and the associated foul odors can be reduced.
On the other hand, temporary toilets are generally considered to be simple, and as a result, complex structures are either impossible or avoided due to cost and other factors. Furthermore, the amount of flushing water that can be used is often limited in temporary toilets due to their installation form. Therefore, it is difficult to apply the above-mentioned structure of permanent toilets, where it is relatively easy to ensure the amount of water and water pressure, to temporary toilets.
For these reasons, it appears that there is little awareness of the need to flush the entire bowl of the toilet, particularly in temporary toilets, and there is still room for improvement in terms of preventing waste from remaining on the bowl surface and the resulting foul odors.

The present invention has been made to solve the problems described above, and aims to provide a toilet water discharge part that is capable of discharging water onto the entire surface of the toilet bowl, whether for permanent or temporary use, but particularly for temporary toilets, a toilet having the water discharge part, and a toilet assembly.

In order to achieve the above object, the present invention is configured as follows.
That is, the toilet water spouting part in the first aspect of the present invention is a toilet water spouting part that is provided on a toilet and spouts flush water downward and to the left and right from the toilet water spouting part toward the bowl surface of the toilet,
a main body portion having a cleaning water discharge port and disposed along the bowl surface;
a discharge port cover that faces the wash water discharge port and the main body portion and is provided integrally with the main body portion while forming a gap between the discharge port cover and the main body portion, the discharge port cover discharging wash water discharged from the wash water discharge port in the downward and left-right directions through the gap;
Equipped with
The main body or the outlet cover is
a first region that forms a first gap between the main body and the outlet cover for discharging the cleaning water downward;
a second region for forming a second gap between the main body and the outlet cover for discharging wash water in the left-right direction,
the first gap and the second gap communicate with each other to form the gap,
The outlet cover is inclined downwardly so as to approach the main body.
Characterized by

The toilet water discharge part in the first aspect above comprises a main body and a discharge port cover, the main body or the discharge port cover having a first region and a second region, and the discharge port cover is inclined downward so as to approach the main body. Therefore, flush water can be discharged from the toilet water discharge part downward from a first gap in the first region, and from a second gap in the second region in each of the left and right directions onto the bowl surface of the toilet. Therefore, by providing the toilet water discharge part on the toilet, it is possible to discharge water onto the entire bowl of the toilet, even in a temporary toilet, and it is possible to suppress the remaining of waste on the bowl surface and the associated generation of bad odors.

The following describes an embodiment of the present invention, a toilet water discharge part, a toilet equipped with this toilet water discharge part, and a toilet assembly, with reference to the drawings. Note that in each drawing, the same or similar components are given the same reference numerals. Also, to avoid the following description becoming unnecessarily redundant and to facilitate understanding by those skilled in the art, detailed descriptions of already well-known matters and duplicate descriptions of substantially identical configurations may be omitted. Furthermore, the contents of the following description and the attached drawings are not intended to limit the subject matter described in the claims.

In the embodiment described below, a Western-style seated toilet in a temporary toilet is used as an example, but the present invention is not limited to this, and can be applied to so-called Japanese-style toilets in temporary toilets, as well as Western-style and Japanese-style toilets in permanent toilets.

First, a schematic configuration of a toilet assembly 500 according to one embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.
This toilet assembly 500 includes a toilet 200, and may further include a water discharge pump 350 for manually discharging flushing water into the toilet 200. In this type of toilet assembly 500, the toilet 200 has a Western-style toilet body 220, and flushing water is discharged onto the bowl surface 210 of the Western-style toilet body 220 from at least three locations in total: the left and right side portions 222a and 222b of the seat front portion 222 of the Western-style toilet body 220, and the seat rear portion 223.

Here, the front seating part 222 refers to the front side of the user when the user is sitting on the toilet 200 during excretion, and the rear seating part 223 refers to the rear side of the user in that state. With reference to FIG. 9, when the angles along the major axis of the Western-style toilet body 220, which is egg-shaped in plan view, are 0 degrees and 180 degrees, the 0 degree side of the minor axis corresponds to the front seating part 222, and the 180 degree side corresponds to the rear seating part 223.

Furthermore, if the center point 221c of the upper opening 221 in the Western-style toilet body 220, which is the intersection point of the major axis and the minor axis, is taken as the vertex, the above-mentioned left and right side portions 222a, 222b each correspond to an angular position of about α degrees from the minor axis. In this embodiment, α is about 33 degrees. Furthermore, this angle α is not limited to the above value, but is a variable that is designed according to the discharge pressure, flow rate, etc. of the flush water.
In this embodiment, when a person weighing approximately 40 to 120 kg steps onto the water discharge pump 350 with one foot bearing the entire weight of the person's body, the discharge pressure is, for example, approximately 0.05 to 0.15 MPa, and the discharge flow rate is, for example, approximately 100 to 200 ml.
In this embodiment, the center point 221c of the upper opening 221 in the Western-style toilet body 220 is offset in the 0-180 degree direction in Figure 9 from the center of a lower opening 229 (described below) in the Western-style toilet body 220. Therefore, when the center of the lower opening 229 is taken as the vertex, the above-mentioned angle α is about 43 degrees.

Furthermore, the toilet assembly 500 has two water discharge systems in the toilet 200: a first water discharge system 300 that discharges flushing water onto the bowl surface 210 by human power, and a second water discharge system 400 that discharges flushing water onto the toilet by means other than human power (e.g., head pressure).

The toilet assembly 500 has the above-mentioned configuration, which allows water to be discharged onto the entire surface of the toilet bowl, thereby making it possible to prevent waste from remaining on the bowl surface 210 and the associated generation of bad odors.

In addition, the toilet assembly 500 has the first water discharge system 300 and the second water discharge system 400, and thus it is possible to discharge flush water from either of them to the Western-style toilet body 220. That is, in a situation where there is no existing flush water piping, such as a temporary one, it is possible to discharge water using the first water discharge system 300, while in a situation where there is an existing flush water piping, it is possible to use the second water discharge system 400 to discharge water onto the entire surface of the toilet bowl by simply connecting the existing flush water piping to the second water discharge system 400, without having to separately install or replace any necessary parts, or change or modify the toilet structure. In this way, the toilet assembly 500 also has the effect of improving the applicability and convenience of the toilet installation location.

In the case of a temporary (simple) toilet, for example, in the toilet assembly 500 configured in this manner, a flapper assembly 10 is connected to the lower opening 229 of the Western-style toilet body 220 as shown in FIG. 1, the Western-style toilet body 220 and the flapper assembly 10 are covered with a cover 20, and an adapter 30 is further attached.
Furthermore, in the case of a temporary toilet, as shown in Figure 2, the toilet assembly 500 with the cover 20 and adapter 30 attached is placed and fixed to the floor member 40 together with the flush water tank 50. In addition, a water discharge pump 350, which will be described below, is attached to the flush water tank 50.
Furthermore, the Western-style toilet body 220, the flapper assembly 10, the cover 20, the adapter 30, the floor member 40, and the flush water tank 50 can be manufactured by blow molding and injection molding of resin material.

Each component of the toilet assembly 500 will now be described in further detail in turn.
First, the toilet 200 will be described.
As described above, the toilet 200 has a Western-style toilet body 220, which, as shown in Fig. 1 etc., has a roughly cone shape, is substantially elliptical (egg-shaped) in plan view, and has a cone-shaped bowl surface 210 between a large-diameter upper opening 221 and a small-diameter circular lower opening 229. The toilet 200 further has a front water spouting part 320 and a rear water spouting part 230. The front water spouting part 320 is the name and number of the toilet assembly 500, and can be read as the toilet water spouting part 100, which will be described in detail later.

The front water discharge part 320 (100) is attached to the left and right side parts 222a, 222b of the seat front part 222 of the Western-style toilet body 220 at the peripheral part 221a of the upper opening 221 of the Western-style toilet body 220. Such a front water discharge part 320 is a part that discharges cleaning water to the left and right side areas 211, 212 of the bowl surface 210 of the Western-style toilet body 220 at the seat front part 222.

The rear water discharge part 230 is provided at the seat rear part 223 of the Western-style toilet body 220, at the location of the periphery 221a of the upper opening 221 in the Western-style toilet body 220. The rear water discharge part 230 is a part that discharges flushing water to the rear region 213 of the bowl surface 210 at the seat rear part 223.
These front water discharge component 320 (100) and rear water discharge component 230 will be described in detail later.

1 and 3, the first water discharge system 300 has a first flushing water pipe 310, at least two (two in this embodiment) front water discharge parts 320 as described above, and one rear water discharge part 230 as described above in this embodiment. The first water discharge system 300 can also have the above-mentioned water discharge pump 350, which is connected to the first flushing water pipe 310 (part A in FIG. 2). Therefore, the first flushing water pipe 310 is a pipe through which flushing water is supplied by human power.

The first flush water pipe 310 to which the discharge pump 350 can be connected is connected to the rear discharge part 230, and is also connected to the two front discharge parts 320 via each pipe branched off at the rear discharge part 230. Therefore, when the discharge pump 350 is connected to the first flush water pipe 310, the flush water delivered from the discharge pump 350 is discharged through the rear discharge part 230 and the front discharge part 320 to the bowl surface 210 of the Western-style toilet body 220.

As shown in Figures 1 and 4, the second water discharge system 400 is a water discharge system to which a second flush water pipe X separate from the first flush water pipe 310 can be connected, and has a water discharge pipe 410. Note that the second flush water pipe X shown in Figures 1 and 4 is not a part of the second water discharge system 400, but is shown for convenience of explanation, and corresponds to, for example, an existing flush water pipe for a flush toilet.

The discharge pipe 410 has a connecting part 412 to which the above-mentioned second flushing water piping X can be connected, and is a separate member from the Western-style toilet body 220, and is arranged extending along the upper opening 221 of the Western-style toilet body 220, and is a pipe that discharges flushing water supplied from the connecting part 412 to the above-mentioned rear area 213 and left and right side areas 211, 212 of the bowl surface 210, that is, to the entire surface of the bowl surface 210. Therefore, the discharge pipe 410 has multiple discharge ports that open toward the bowl surface 210 so that water can be discharged to the entire surface of the bowl surface 210. Incidentally, when the first water discharge system 300 is used, a closing cap is usually attached removably to the connecting part 412 to close it off.
1, a top cover 250 is placed on the upper opening 221 side of the Western-style toilet body 220, and the top cover 250 is fixed integrally with the Western-style toilet body 220. The water discharge pipe 410 is disposed between the peripheral wall surface 251 of this top cover 250 and the upper opening 221 of the Western-style toilet body 220, and is hidden from the outside.

The following is a detailed explanation of the above-mentioned front water spouting component 320 (100) and rear water spouting component 230. Note that, in this explanation, the front water spouting component (toilet water spouting component) is given the number 100.
First, the front water discharge part 100 (which may be read as the toilet water discharge part 100) will be described mainly with reference to FIGS. 5A-5D (sometimes collectively referred to as FIG. 5) to FIG.
As described above, the front water discharge part 100 is a part that can be attached to two locations, the left and right side parts 222a, 222b of the seat front part 222 of the Western-style toilet body 220, and is a part that discharges flushing water supplied from the above-mentioned first flushing water piping 310 from the toilet water discharge part 100 toward the bowl surface 210 of the Western-style toilet body 220 in a downward direction 190 and a left-right direction 192. Note that the downward direction 190 refers to the direction in which the flushing water flows down the bowl surface 210 in response to the direction of gravity and the directions toward the vicinity of both sides of that direction. Also, the left-right direction 192 refers to the left and right directions relative to the downward direction 190, which are located above the downward direction 190.
In addition, in this embodiment, the front water-discharge parts 100 are installed in at least two locations on the left and right side portions 222a, 222b, but may be installed in three or more locations on the seat front portion 222 if necessary.

In addition, there are two types of front water spouting parts 100: a first type shown in Fig. 7 and a second type shown in Fig. 5A-5D, and either type can be installed on the Western-style toilet body 220 as the front water spouting part 320 described above. Here, the second type corresponds to an improved version of the first type. Therefore, the second type may be referred to as the improved version and the first type as the prototype.
In terms of function and operation, the second type (improved type) used in this embodiment is superior to the first type (prototype), as described below. In the following, the second type will be referred to as the front water spouting part 100 and described. For ease of explanation, the first type will be numbered as the front water spouting part 100P, and the components of the front water spouting part 100P that are common to the second type front water spouting part 100 will use the same reference numerals as the front water spouting part 100. As described above, the front water spouting part 320 is a concept that includes both the front water spouting part 100 and the front water spouting part 100P.

The front water discharge part 100 has a main body 110 which is molded from a resin material in this embodiment, and a discharge port cover 130 which is integral with the main body 110 and which is made of a metal plate in this embodiment.
5 and 6, the main body 110 has a gap forming portion 112 and a base portion 114 that is located above the gap forming portion 112 and serves as a mounting seat for the outlet cover 130. In this embodiment, the gap forming portion 112 has a roughly semicircular shape in a plan view, and is a portion that forms a gap 150 described below together with the outlet cover 130. In this embodiment, the gap forming portion 112 and the base portion 114 are integrally molded.
Furthermore, the main body 110 has the flush water discharge port 111a of the nozzle 111 extending from the main body 110 at the top of the gap forming portion 112, and the gap forming portion 112 is installed along the bowl surface 210 of the Western-style toilet main body 220. In this embodiment, the flush water discharge port 111a is oriented with its outlet surface approximately parallel to the bowl surface 210 as shown in Fig. 5A, but the outlet surface may also be oriented toward the downward 190 side. Furthermore, regarding the inner diameter of the nozzle 111, the vertically extending portion of the nozzle 111 and the horizontally extending portion including the flush water discharge port 111a are shown to have the same diameter in Figs. 5D and 6, but the inner diameter of the horizontally extending portion may be made smaller than the vertically extending portion, and the horizontally extending portion may be configured to expand in a tapered manner toward the flush water discharge port 111a. These configurations make it easier to mold the main body 110 and also enable adjustment of the water discharge pressure in the front water discharge part 100, as described below, which contributes to improved cleaning efficiency.

The nozzle 111 is connected to the first cleaning water pipe 310 described above. In this embodiment, the nozzle 111 is integrally formed with the main body 110, but it may be, for example, detachable from the main body 110. In this detachable form, the nozzle 111 is included in the first cleaning water pipe 310. Therefore, the main body 110 does not have the nozzle 111, and the first cleaning water pipe 310 can be directly connected to the main body 110.

The outlet cover 130 is a part that faces the wash water outlet 111a in the main body 110 and the main body 110, and forms a gap 150 (FIGS. 5B and 6) between it and the main body 110, and is provided integrally with the main body 110 via the base 114 as described above. Such an outlet cover 130 is a cover that causes the wash water discharged from the wash water outlet 111a to be discharged downward 190 and in each of the left and right directions 192 described above through the gap 150.
Furthermore, reference numeral 290 denotes an O-ring used when installing the front water spouting part 100 onto the Western-style toilet body 220 .
5B, the outlet cover 130 is made of a flat metal plate and has a rigidity that can withstand the discharge pressure of the wash water discharged from the wash water outlet 111a, that is, a rigidity that does not deform under the discharge pressure. Here, a degree of not deforming means a degree of deformation that makes it difficult to properly discharge wash water from the front water discharge part 100 downward 190 and left-right direction 192, in other words, that makes it insufficient to discharge wash water to the left and right side regions 211, 212 of the bowl surface 210, or in other words, that changes the dimension of the gap 150 formed between the outlet cover 130 and the main body 110.
In this embodiment, the outlet cover 130 made of a metal plate is attached and fixed to the main body 110 with bolts and nuts as an example of fastening members.
However, the outlet cover 130 is not limited to being made of metal, and may be made of, for example, a resin material having high rigidity, and may be molded integrally with the main body 110 using the resin material having high rigidity.

In relation to the above-mentioned gap 150 formed with the outlet cover 130, the main body 110 further has the following configuration.
5 and 6, the gap forming portion 112 of the main body 110 has a first region 112A that forms a first gap 151 with the outlet cover 130 in order to discharge wash water downward 190, and a second region 112B that forms a second gap 152 with the outlet cover 130 in order to discharge wash water in each of the left and right directions 192. Such first gap 151 and second gap 152 communicate with each other to form the gap 150.

As shown in FIG. 5A, the first region 112A has a sector shape that spreads downward 190 from the cleaning water outlet 111a in a plan view, and the second region 112B has a triangular shape and is located above both wing portions 112AS of the sector-shaped first region 112A in a plan view.

Also, as shown in Figures 5 and 6, in the thickness direction 138 of the outlet cover 130 fixed to the main body 110, the dimension (thickness) of the first gap 151 is larger than the dimension of the second gap 152.

Furthermore, the first region 112A is configured so that the first gap 151 gradually increases in size along the downward direction 190, in other words, along the radial direction of the semicircular gap forming portion 112, in the direction in which the cleaning water flows (the discharge direction). In other words, the first region 112A is configured so that the thickness of the main body portion 110 gradually decreases in the discharge direction of the cleaning water along the downward direction 190. Similarly, each second gap 152 is configured so that the size of the second gap 152 gradually increases along each left-right direction 192, in other words, along the above-mentioned radial direction, in the discharge direction of the cleaning water. In other words, each second region 112B is configured so that the thickness of the main body portion 110 gradually decreases in the discharge direction of the cleaning water along each left-right direction 192.

Therefore, the main body 110 has a step between the first region 112A and the second region 112B, and each boundary 112c (Figs. 5A and 6) between the first region 112A and the two second regions 112B is located at each of the two wing portions 112AS. In addition, each of the two wing portions 112AS is formed so that each boundary line 112d (Fig. 5A) at the two boundaries 112c intersects above the cleaning water outlet 111a. Therefore, the cleaning water outlet 111a in the main body 110 is located in the first region 112A. The boundary line 112d can also be said to be the ridge line of the two wing portions 112AS.

As shown in FIG. 5A, the angle β from the upper end of the gap forming portion 112 to each boundary line 112d, with the intersection of each boundary line 112d as the apex, is approximately 30 degrees in this embodiment. Note that the angle β is not limited to the above-mentioned value, but is a variable that is designed depending on the discharge pressure and flow rate of the cleaning water, etc. Note that in this embodiment, as described above, the discharge pressure is, for example, approximately 0.05-0.15 (MPa), and the discharge flow rate is, for example, approximately 100-200 (ml).

As shown in FIG. 5B, in this embodiment, the mounting surface 114a of the outlet cover 130 on the base 114 of the main body 110 is a surface that is slightly inclined downward toward the lower portion 190. With this configuration, the outlet cover 130 installed on the base 114 is positioned so that it is slightly closer to the main body 110 toward the lower portion 190. It is also possible not to form the surface as an incline.

Alternatively, with or without the downward inclination of the mounting surface 114a, the portion of the outlet cover 130 below the mounting surface 114a on the lower 190 side may be bent or curved slightly toward the main body 110 toward the lower 190, as shown by the dotted line in FIG. 5B. Note that the dotted line is exaggerated compared to the actual state.

The front water discharge part 100 has the above-described configuration, so that the wash water discharged from the wash water discharge port 111a hits the discharge port cover 130, and a portion of the wash water is discharged downward 190 onto the bowl surface 210, and the remaining wash water is discharged in the left-right direction 192. Specifically, because the wash water discharge port 111a is disposed in the first region 112A, the front water discharge part 100 can basically discharge the wash water downward 190 onto the bowl surface 210 through the first gap 151, and further, by providing the second region 112B on both the left and right sides of the front water discharge part 100, the wash water can be discharged in the left-right direction 192 onto the bowl surface 210.

At this time, by providing a step between the first gap 151 and the second region 112B as described above, that is, by configuring the second gap 152 to be narrower than the first gap 151, the water discharge pressure in the second gap 152 can be made higher than the water discharge pressure in the first gap 151. Therefore, although the total area of the two second regions 112B, in other words the total volume of the two second gaps 152, is smaller than the area of the first region 112A (the volume of the first gap 151), the high water discharge pressure makes it possible to discharge water to both sides of the downward 190, that is, over a wide range in the left-right direction 192.

Therefore, the front water discharge part 100 can also discharge wash water into the shaded area 215 of the bowl surface 210 shown in Figure 8. As a result, it is possible to discharge wash water over a wider area than before, that is, the entire surface of the bowl surface 210 in the front seating area 222 and even a portion of the rear seating area 223.

As shown in Figs. 5B and 6, the length dimension of the outlet cover 130 in the downward direction 190 is equal to the length dimension of the main body 110, but as shown in Fig. 5D, the width dimension in the left-right direction 192 is greater than the width dimension of the main body 110. This configuration prevents the higher pressure flush water discharged in the left-right direction 192 from the second gap 152 from protruding toward the center of the Western-style toilet body 220, allowing water to flow more efficiently in the left-right direction 192 along the bowl surface 210.

In addition, as described above, by adopting a configuration in which the outlet cover 130 is located closer to the main body 110, the water discharge pressure from the front water discharge part 100 to the bowl surface 210 can be increased, making it possible to further improve cleaning efficiency.

In addition, the following configuration can also be adopted as a modified example of the front water discharge part 100.
That is, in this embodiment, as described above, the method of forming the first gap 151 and the second gap 152 is to form the first region 112A and the second region 112B in the main body 110, while a flat plate material is used for the outlet cover 130. As a modification of this configuration, it is also possible to adopt a form in which the configurations of the main body 110 and the outlet cover 130 are reversed. This modification is referred to as the front water discharge part 100C.
That is, as shown in Figure 10, the main body portion 110C of the front water-spouting part 100C has a base portion 114 that is configured in the same manner as that of the main body portion 110 of the front water-spouting part 100, but each area in the main body portion 110C of the front water-spouting part 100C that corresponds to the first area 112A and the second area 112B of the main body portion 110 is configured with a flat surface.
On the other hand, the outlet cover 130C of the front water spouting part 100C has a first region 132A and a second region 132B corresponding to the first region 112A and the second region 112B described above.
This type of front water spouting part 100C can also achieve the effects described above with the front water spouting part 100.

Next, the first type (prototype) front water spouting part 100P will be described.
7, front water spouting part 100P differs from front water spouting part 100 in that it does not have second region 112B, in other words, second region 112B has the same configuration as first region 112A. The other configurations are the same as front water spouting part 100, and detailed description thereof will be omitted here.

As such, the front water-spouting part 100P has a configuration that is almost the same as the front water-spouting part 100 described above, and can therefore basically achieve the effects of the front water-spouting part 100 described above. However, since it does not have the second region 112B, there is a tendency for water to be slightly weaker in the left-right direction 192 compared to the front water-spouting part 100. However, it is possible for water to flow over almost the entire surface of the bowl surface 210 at the front of the seat 222.

Next, the rear water discharge component 230 will be described with further reference to Figures 11A and 11B (sometimes collectively referred to as Figure 11).
As already explained and as shown in Figure 1, the rear water discharge part 230 is a part to which the above-mentioned first flush water piping 310 is connected, and which discharges flush water supplied from the first flush water piping 310 from the rear water discharge part 230 downward 194 and left-right 196 toward the bowl surface 210 at the rear of the seat 223 of the Western-style toilet body 220. This type of rear water discharge part 230 is installed in the 180 degree position shown in Figure 9, in the peripheral part 221a of the upper opening 221 of the Western-style toilet body 220.
The downward direction 194 refers to the direction in which the wash water flows down the bowl surface 210 in response to the direction of gravity and the directions toward both sides of the direction. The left-right direction 196 refers to the left-right direction relative to the downward direction 194, which is located above the downward direction 194.

The rear water discharge part 230 is a part molded from a resin material, and has wings 232 that extend from the 180 degrees toward the left and right by 90 degrees along the periphery 221a of the upper opening 221 of the Western-style toilet body 220, and a nozzle 234 that is molded integrally with the wings 232 and to which the first flush water pipe 310 is connected. The nozzle 234 is positioned so as to protrude outside the Western-style toilet body 220.

The nozzle 234 has one rear nozzle 234a connected to the main first flushing water pipe 310A, which is connected to the discharge pump 350, and two front nozzles 234b connected to first flushing water pipes (for ease of explanation, referred to as branch first flushing water pipes 310B) that branch off from the nozzle 234 and are connected to each of the front discharge parts 100. As shown in the figure, the rear nozzle 234a has a larger inner diameter than each of the front nozzles 234b.

As shown in FIG. 11B, the wing portion 232 has a water discharge path 232a that communicates with the flow path in the rear nozzle 234a. The water discharge path 232a extends along the wing portion 232 inside the wing portion 232 and is open to the bowl surface 210. Therefore, the cleaning water supplied through the first main cleaning water pipe 310A is discharged to the bowl surface 210 over the entire length of the wing portion 232 via the water discharge path 232a and flows out downward 194 and left-right 196.

Here, as described above, the inner diameter of the rear nozzle 234a for the rear water spouting part 230 is larger than the inner diameter of the front nozzle 234b for the front water spouting part 100, and since flush water flows into the rear water spouting part 230 linearly from the first main flush water piping 310A, the rear water spouting part 230 spouts more water than the front water spouting part 100. Furthermore, the size of the rear water spouting part 230, including the wing part 232, is also larger than that of the front water spouting part 100. Therefore, water is spouted from one rear water spouting part 230 to the bowl surface 210 in the rear seating part 223 of the Western-style toilet body 220, and water is spouted from two front water spouting parts 100 to the bowl surface 210 in the front seating part 222.
With the rear water-spouting component 230 configured in this manner, it is possible to spout water onto the entire surface of the bowl surface 210 at the rear seat portion 223 of the Western-style toilet body 220 .

The operation, function, and method of use of the toilet assembly 500, which is configured as described above and includes the toilet 200 having the front water spouting part (toilet water spouting part) 100, will be described below.
As described above, the toilet assembly 500 has a first water discharge system 300 and a second water discharge system 400, and flushing water can be discharged from either of these systems into the Western-style toilet body 220.
When the toilet assembly 500 is used as, for example, a temporary toilet and the first water discharge system 300 is used, the user operates (e.g., steps on) the piston portion of the water discharge pump 350 that can be provided in the toilet assembly 500, and the flush water in the flush water tank 50 passes through the main first flush water pipe 310A of the first flush water pipe 310 and is supplied to the rear water discharge part 230, and also branches at the rear water discharge part 230 and passes through each branch first flush water pipe 310B of the first flush water pipe 310, and is supplied to each of the two front water discharge parts 100. Then, this flush water is discharged from the rear water discharge part 230 to the bowl surface 210 in the rear seat part 223 of the Western-style toilet body 220, and from the two front water discharge parts 100 to the bowl surface 210 in the front seat part 222, respectively, and is discharged over the entire surface of the bowl surface 210.

This makes it possible to prevent dirt from remaining on the bowl surface 210 and the associated generation of bad odors.

On the other hand, in a situation where existing flush water piping exists, the second water discharge system 400 can be used.
In this case, the already-installed second flushing water piping X described above is connected to the connecting part 412 in the second water discharge system 400. Then, by operating a water discharge device provided in the second flushing water piping X, the flushing water that has passed through the second flushing water piping X is supplied to the second water discharge system 400 and discharged from the multiple water discharge ports of the water discharge pipe 410 via the connecting part 412 onto the entire surface of the bowl surface 210.
As a result, it is possible to suppress the residue of dirt adhering to the bowl surface 210 and the associated generation of bad odors.
It is also possible to use the first water discharge system 300 and the second water discharge system 400 in combination.

The present invention is applicable to a toilet spouting component that is attached to a flush toilet bowl, a toilet bowl equipped with this spouting component, and a toilet bowl assembly.
