Description

[Detailed description of the invention] Industrial field of application: This invention relates to a Japanese-style flush toilet for buildings with reinforced steel and steel-framed concrete structures.

Conventional technology: Japanese-style flush toilet A currently installed in the above building
As shown in FIG. 5, since the lower part of the hole C is inserted into the large hole C drilled in the floor slab B, the distance F between the upper surface D of the floor slab B and the floor surface E is is relatively small. The manner in which the toilet bowl A is installed shown in FIG. 5 is not restricted by the height H of the toilet bowl A.

Problems that the invention aims to solve: Recently, it has been pointed out that the presence of a large hole C in the floor slab B for installing the toilet bowl A is unfavorable from a fire safety perspective. If the above-mentioned large hole C is not provided in the toilet bowl A, the distance F from the top surface D of the floor slab B to the floor surface E is
As a result, the position of the floor surface E rises as shown in FIG. 6. In order to reduce the dimension F without drilling a large hole C in the floor slab B, the height H of the toilet bowl A can be reduced. This is blocked by an odor trap located directly below the flow bed.

Means for Solving the Problems: In order to solve the above problems, this proposal has the toilet body without an odor-preventing trap removably supported by a bottomed toilet support material, and a part of the bottom surface of the toilet body. A siphon is provided on the toilet supporting material with a curved groove that works together with the odor-preventing trap to form an odor-preventing trap, extending laterally to avoid interference with the flow bed of the toilet bowl body, and allowing flushing water to flow through the odor-preventing trap. A sealing material is interposed between the toilet main body and the toilet supporting material to block the entry of air that inhibits the occurrence of the action.

Function: In the above-mentioned device according to the present invention, since the curved groove forming the odor-preventing trap is provided so as to protrude laterally, the height B of the toilet can be reduced by lowering the position of the flow bed of the toilet main body.

The sealing material interposed between the toilet bowl body and the toilet bowl support material acts to prevent the entry of air that weakens or interrupts the siphoning effect of flushing water while passing over the highest portion of the trap flow path.

Since the curved groove on the toilet bowl support member is exposed by removing the toilet bowl body, it is relatively easy to repair the odor trap when it becomes clogged with a large foreign object.

Embodiment: FIG. 1 is a vertical side view showing an example of a Japanese-style flush toilet according to the present invention, and FIG. 2 is a plan view of the toilet shown in FIG. 1. In these figures, 1 is a toilet main body which is not provided with an odor trap, and 2 is a toilet supporting member that supports the toilet main body 1. The toilet support 2 is installed on the floor slab 3.

The toilet supporting member 2 has a bottom, and a curved groove 5 that cooperates with a part of the outer surface 4 of the toilet main body 1 to form an odor trap extends laterally as shown in FIG. provided. Washing water from the flow bed 6 of the toilet main body 1 enters the curved groove 5 through the flow outlet 7. The outflow end of the curved groove 5 is a drain port 8, and the drain port 8 is communicated with a drain pipe 9.

FIG. 3 shows the sideward protrusion of the curved groove 5 with the toilet bowl main body 1 removed, and also shows the sealing material 10a interposed between the toilet bowl main body 1 and the toilet supporting member 2,
10b is shown. The sealing materials 10a and 10b function to prevent the flow of washing water from the upward slope 11 in the curved groove 5, over the saddle portion 12, and to the downward slope 13 from being obstructed by the intrusion of air.

Since the curved groove 5 is provided so as to protrude laterally, it is desirable to provide means for directing the flow of washing water in the direction of the protrusion. Reference numeral 14 denotes a washing water branch discharge pipe provided as this means, which is opened from a discharge port 15 at the beginning of the upward slope 11, and discharges the washing water in the direction of the arrow.

Figure 4 is a cross section taken in the direction of line 4-4 in Figure 2,
Curved groove 5 on the outer surface 4 of the toilet bowl body 1 and on the toilet support member 2
The highest part (the part above the saddle part 12) of the flow path 16 of the deodorizing trap formed by the above is shown.

Effects of the invention: This invention solves the problem that occurs when large holes are not made in the floor slab, which is undesirable from a fire prevention perspective, in that the total height of the toilet bowl causes the floor surface to rise, by changing the installation method of the odor trap. It is something to be avoided. Furthermore, eliminating the need to drill large holes in the floor slab has the effect of making the construction of the floor slab B easier.

Claims (1)

[Scope of utility model registration request] The toilet body, which does not have a flow path for the odor trap, is removably supported by a bottomed toilet supporting material, and the curved groove that forms the odor trap in cooperation with a part of the outer surface of the toilet body is connected to the flow path of the toilet body. A sealing material is provided on the toilet supporting material, extending to the sides to avoid interference with the floor, and blocking air from entering the toilet body, which prevents the occurrence of the siphon effect that causes flushing water to flow through the odor-preventing trap. A Japanese-style flush toilet characterized by being interposed between the toilet bowl supporting material.
