In this Western style flush toilet, the wash water stored in the wash tank is supplied to the rim water passage 94 a via the distributor 92, and the wash water flows down to the bowl portion 93 from there. The washing water that has washed the bowl portion 93 causes a siphon effect by the trap portion 95 and is discharged to the rear side along the trap portion 95 together with the filth.
[0004]
[Problems to be solved by the invention]
However, in the conventional Western-style flush toilet, the size of the Western-style toilet body 91 has not been studied, and the overall size tends to increase. For this reason, in recent houses and the like, the space is not saved, and the toilet room in which a relatively large space cannot be secured is increasingly narrowed.
[0005]
This invention is made | formed in view of the said conventional situation, Comprising: It is set as the problem which should be solved to provide the western-style flush toilet bowl which implement | achieved size reduction.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present inventor has intensively studied and completed the present invention by paying attention to the center of the inlet extending in the horizontal direction from the bowl portion to the trap portion.
[0007]
That is, the Western-style flush toilet of the present invention comprises a porcelain Western-style toilet body having a bowl portion and a trap portion connected to the lower end of the bowl portion, and the bowl portion is washed with washing water, In a Western style flush toilet that drains the washing water to the rear side along the trap part,
[0008]
A cleaning device that is directly connected to a water supply pipe that supplies the cleaning water from the outside and that can discharge the cleaning water by opening and closing a valve,
The western-style toilet body has a nozzle opening which is formed through the trap portion, and the center inlet extending in the horizontal direction of the trap portion leading to said trap portion from said bowl portion, horizontal of the bowl portion Located before the center in the direction,
The nozzle port is provided with a jet nozzle connected to the cleaning device by a jet pipe, and the cleaning water is jetted toward the top end of the trap portion by the jet port of the jet nozzle. It is configured separately from the western-style toilet body .
[0009]
As shown in FIG. 7, the conventional Western-style flush toilet has a center TO of the inlet TI extending in the horizontal direction of the trap portion 95 extending from the bowl portion 93 to the trap portion 95 as a central BO in the horizontal direction of the bowl portion 93. It was always located behind. For this reason, the full length of the western-style toilet body 91 comprised by the bowl part 93 and the trap part 95 is necessarily long in the front-back direction. In contrast, in the Western style flush toilet of the present invention, the center of the entrance of the trap portion is located before the center of the bowl portion, and the overall length of the Western style toilet body is shortened in the front-rear direction.
[0010]
Therefore, the Western-style flush toilet of the present invention is downsized as a whole. For this reason, space saving can be realized by adopting this Western style flush toilet in a recent house or the like. For this reason, even if it is a toilet room which cannot ensure a comparatively big space, a vast feeling can be exhibited. Further, since the space is saved, the user can easily move in the toilet room, and the space can be effectively used for other purposes. Furthermore, since the Western-style flush toilet is thus miniaturized, resource saving and low cost for manufacturing can be realized.
[0011]
Here, the inlet of the trap part is a part from the bowl part to the trap part, and extends in the horizontal direction. The part from the bowl part to the trap part is determined by the lower end of the rear wall of the bowl part. As shown in FIG. 1, the center TO of the entrance TI of the trap portion is formed symmetrically in a normal Western-style toilet body, so each end TR, TF in the front-rear direction of the entrance TI is one point. If there is, it is the midpoint of the line segment TL connecting the rear end TR and the front end TF. In addition, as shown in FIG. 2, if at least one end in the front-rear direction of the entrance TI is the horizontal line TH, it is similarly determined by the center point THO of the horizontal line TH.
[0012]
Further, as shown in FIG. 3, the center BO in the horizontal direction of the bowl portion B is formed symmetrically with the bowl portion B in a normal Western-style toilet body. If it is a point, it is determined by the perpendicular assumed in the middle of the perpendicular BR standing at the rear end and the perpendicular BF standing at the front end. As shown in FIG. 4, if at least one end of the bowl part B in the front-rear direction is a horizontal line BH, it is determined in the same manner by the perpendicular line BHO standing at the middle point of the horizontal line BH.
[0013]
In the western style flush toilet of the present invention, it is preferable that the upstream side of the top end of the trap portion is formed by the rear wall of the bowl portion. If the upstream side is formed by a wall different from the rear wall of the bowl part, the wall has a thickness in the front-rear direction, and the thickness between the rear wall of the bowl part and the wall in the front-rear direction is also great. With these dimensions, the overall length of the Western-style toilet body becomes longer in the front-rear direction. On the other hand, if the upstream side is formed by the rear wall of the bowl portion, the size is not generated, and the overall length of the Western-style toilet body is shortened in the front-rear direction.
[0014]
Here, the top end of the trap portion is a portion that forms the accumulated water in the bowl portion, and is the uppermost position of the inner bottom surface that forms a water channel having an inverted U shape. The top end of this trap part is determined as one point or a horizontal line by the cross-sectional shape orthogonal to the discharge direction of the trap part.
[0015]
Further, in the Western style flush toilet of the present invention, when the trap part has a cylindrical part upstream from the top and having an inner surface as a cylindrical surface, the axial line of the cylindrical part extends at 45 degrees or more with respect to the horizontal direction. It is preferable. If it is like this, shortening in the front-back direction of the western-style toilet body by a trap part can be implement | achieved, ensuring the water level of stored water.
[0016]
Furthermore, in the western style flush toilet of this invention, it is preferable that the downstream side is bent ahead from the top end of a trap part. If the total length of the Western-style toilet body is shortened, at least the pedestal portion that conceals the trap portion can be made smaller. If the pedestal portion is made smaller in this way, the outlet of the trap portion tends to approach the wall surface of the wall behind the pedestal portion, and there is a possibility that it cannot be suitably connected to the drain socket. In this respect, if the downstream side is bent forward from the top end of the trap portion, even if the pedestal portion is made smaller, the discharge port is separated from the rear side wall surface in the pedestal portion and can be suitably connected to the drain socket.
[0017]
The cleaning device is directly connected to the water supply pipe of the water pipe for supplying cleaning water than the outer portion, it adopts what can discharge washing water by opening and closing the valve. The effect of the present invention is great when this cleaning apparatus is employed. A conventionally known cleaning tank temporarily stores and discharges cleaning water, and requires a considerable volume. For this reason, if the washing tank which requires considerable volume is employ | adopted, adopting the western-style toilet body which concerns on this invention in order to aim at the enlargement of a narrow toilet room, the effect of this invention will be reduced. In this respect, if this cleaning apparatus is employed, a conventional cleaning tank is not required, and therefore, the effect of the present invention of enlarging a narrow toilet room can be emphasized.

Here, the inlet TI of the trap portion 15 is a portion from the bowl portion 13 to the trap portion 15 and extends in the horizontal direction. The portion from the bowl portion 13 to the trap portion 15 is determined by the lower end 13d (TR) of the rear wall 13b of the bowl portion 13. The center TO of the entrance TI is the midpoint of the line segment TL connecting the lower end 13d (TR) and the front end TF of the entrance TI.
[0023]
Further, the center BO in the horizontal direction of the bowl part 13 is determined by a perpendicular assumed between the perpendicular line BR standing at the rear end 13r of the bowl part 13 and the perpendicular line BF standing at the front end 13f of the bowl part 13. Here, the rearmost portion of the boundary between the bowl portion 13 and the rim 14 is the rear end 13r of the bowl portion 13, and the frontmost portion is the front end 13f of the bowl portion 13.
[0024]
Moreover, the trap part 15 has the cylindrical part 15h which makes an inner surface a cylindrical surface upstream from the top end 15d. The axial line 15g of the cylindrical portion 15h extends at an angle θ (θ = 45 degrees) with respect to the horizontal direction.
[0025]
A drain socket 17 extending vertically is connected to the discharge port 15c downstream from the top end 15d of the trap portion 15. The drain socket 17 is connected to a drain pipe (not shown) protruding from the floor surface.
[0026]
In the Western-style flush toilet constructed as described above, cleaning water is supplied from the cleaning device 12 to the rim water passage 14 a via the rim piping 20 and then flows down to the bowl portion 13. Further, the cleaning water is ejected from the cleaning device 12 through the jet pipe 18 and the jet nozzle 19 from the jet port 19a, and the siphon effect is forcibly generated in the trap portion 15. Thus, the cleaning water is discharged along with the filth to the rear side along the trap portion 15, and is discharged from the discharge port 15 c to the drain pipe through the drain socket 17.
[0027]
Thus, in this Western style flush toilet, the center TO of the inlet TI extending in the horizontal direction of the trap portion 15 is located in front of the center BO of the bowl portion 13 in the horizontal direction. Is shorter. In addition, since the axial core line 15g of the cylindrical portion 15h of the trap portion 15 extends at 45 degrees with respect to the horizontal direction, while securing the water level of the stored water, in the front-rear direction of the western-style toilet body 11 by the trap portion 15. The length of is shortened. Furthermore, since this Western style flush toilet bowl does not have a washing tank for temporarily storing washing water, the overall length of the Western style toilet bowl body 11 is particularly short.
[0028]
Therefore, since this Western-style flush toilet is miniaturized as a whole, the toilet room can be saved in space, and a sense of vastness can be exhibited even in a toilet room where a relatively large space cannot be secured. Further, in this Western style flush toilet, the user can easily move in the toilet room, and the space can be effectively used for other purposes. Furthermore, since the Western-style flush toilet is thus miniaturized, resource saving and low cost for manufacturing can be realized.
