Of course, this discharge path 6c may communicate with the floor wall surface of the toilet bowl main body 6.

The low tank 7 is a device chamber 6b of the toilet main body 6.
A part of the lower part of the tank is housed in the tank mounting port on the top side of the tank. The low tank 7 has a rectangular opening that is slightly smaller than the tank attachment opening of the toilet main body 6 at its upper surface. The fixing lower part of the low tank 7 has a prismatic shape with the bottom part of one corner (the front side in the drawing) cut off, and when viewed from the side, it is an inverted L.
It is shaped like a letter. That is, the low tank 7
Even after it is fixed, an inspection port that opens over a wide area is formed between this excised space and the tank installation port of the device chamber 6b in the toilet main body 6. . The inspection port is used when maintaining cleaning equipment members etc. that may be installed in the equipment room 6b. The fixing structure between the low tank 7 and the toilet main body 6 is as shown in FIG. 3. FIG. 3 is a partial sectional view seen from the direction of arrow A in FIG. Toilet bowl body 3
Although it does not appear in FIG. 2, as is clear from FIG. 3, there is a hole in the top opening of the equipment chamber 6b on the back side of the bottom of the low tank 7, around the opening of the tank installation port in the longitudinal direction of the top opening. A seat 9 for the low tank 7 is provided to cover about 1/3 of the tank. Two to four bolt holes 9a, 9a are drilled in the seat 9, and a bolt 10 having a so-called internal and external double screw structure, in which threads are carved on the inner and outer peripheral surfaces, is attached. It is being The bolt 10 is inserted through the lower surface of the seat 9, and a nut 11 is screwed into the outer circumferential thread portion protruding from the upper surface of the seat 9. The bottom of the low tank 7 has bolt holes 9a and 9 of the seat 9.
Screw holes 7a, 7a, which correspond to the holes 7a and 7a, respectively, are bored. Therefore, these low tank 7 and toilet bowl main body 6
To fix the low tank 7 to the seat 9 of the toilet main body 6
This is done by screwing the bolt 12 placed on top and then fitted with the packing 13 from inside the low tank 7 into the internal threaded hole of the bolt 10 having the internal and external double screw structure.

In FIG. 2, a low tank cover 8 is formed to cover the low tank 7. The opening on the lower side of the low tank cover 8 has the same size as the tank mounting opening on the upper side provided in the device chamber 6b of the toilet main body 6, and the low tank cover 8 is placed on the upper part of the device chamber 6b. When it is fixed in place, its outer shape is integrally continuous. The lower peripheral wall of the low tank cover 8 has a total of four fixing holes, two sets of fixing holes 8a, 8a closer to the toilet bowl exterior part 6a of the toilet main body 6 and fixing holes 8b, 8b closer to the back of the toilet room. , each set is bored facing each other. The fixing structure between the low tank cover 8 and the toilet main body 6 is different between the fixing holes 8a and 8b, and FIG. 4A shows the case of the fixing hole 8a, and FIG. are shown in cross-sectional views.
As shown in FIG. 2, a short flange 14 is provided on the inner surface of the opening of the toilet main body 6 on the side opposite to the seat 9, and FIGS. It shows the short flange portion 14 closer to the toilet bowl exterior portion 6a and closer to the back of the toilet room. First, Fig. 4A will be explained. An L-shaped metal fitting 15 is fastened to the short collar portion 14 with appropriate bolts and nuts. The rising plate portion 15a of the L-shaped fitting 15 is provided with a screw hole 15b that matches the fixing hole 8a of the low tank cover 8 after the low tank cover 8 is attached. Therefore, the low tank cover 8 and the toilet bowl body 6
When installing the low tank cover 8, place and fix the low tank cover 8 on the top surface of the device chamber 6b in the toilet main body 6,
From the outer surface of the low tank cover 8, screw the screw 18 with the washer 19 inserted into the screw hole 15b of the L-shaped fitting 15. In addition, in the same figure, screw 18
has an internal and external double screw structure, and a cosmetic screw 17 is screwed on after screwing. Next, FIG. 4B will be explained. The fixing structure in the figure is roughly the same as the fixing structure described above, but the mounting fittings used are plate-shaped fittings 16. Therefore, the plate-shaped metal fitting 16 is fixed to the toilet main body 6 in the same way as the fixation to the low tank cover 8 in the above-mentioned fixing structure, and two decorative screws 1 are provided on the outer peripheral surface of the present toilet.
7 and 17 are exposed. However, the fixing structure as described above is used only at the back of the toilet room of the proposed toilet bowl, and as can be seen in FIG. 2, these decorative screws 17, 17 are relatively invisible.
Note that the detailed configuration and shape of the toilet bowl of the present invention can be changed as appropriate depending on the mode of implementation.
