DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a toilet bowl and a method for manufacturing the same.

[0002]

2. Description of the Related Art In a conventional toilet, as shown in FIG.
A rim 2 and a ball surface 3 are provided at an upper portion, and a drainage channel 9 composed of separate molded bodies (adhesive plates) 4, 5, 6 and an outer wall 7 and a bottom wall 8 is supported by the outer wall 7. Here, the space 10 is formed so as to be surrounded by the bent drainage channel 9. The space 10 is provided with an air hole 11 for preventing damage due to air expansion during the firing step. The drainage channel 9 of the toilet bowl 15 after firing requires two qualities. 1
One is to prevent water leakage, and the other is to
When the water is sealed from the upper part to the upper part of the drainage channel, the performance that the odor at the lower part of the drainage channel 9 does not reach the ball surface due to the water sealing is maintained. Conventionally, in order to confirm the above two performances, there is a water leakage inspection for confirming the presence or absence of water leakage when water is passed through the ball surface 3 and the drainage channel 9, and a trap leakage for confirming the presence or absence of cracks in the wall 5 portion. Inspection was underway.

[0003]

In the conventional toilet bowl shown in FIG. 2, since the space 10 is connected to the drainage channel 9 by the air hole 11, the presence or absence of cracks in the wall 5 can be determined only by the water leakage inspection. Therefore, it was necessary to perform the above trap leak inspection separately, and the workability of the inspection was poor. In view of the above, an object of the present invention is to provide a toilet bowl and a method for manufacturing the same, which can simultaneously perform the above-described water leakage inspection and trap air leakage inspection.

[0004]

According to the present invention, in order to achieve the above object, there is provided a drainage channel bent below a ball surface,
A toilet having a space surrounded by the drainage channel,
A toilet is provided, wherein a hole is provided in a partition between the space and a space other than a drainage passage adjacent to the space and communicating with outside air. By doing so, if there is a crack in the wall 5, the water leaks during the water leak test, so that the water leak test and the trap leak test can be performed simultaneously. Therefore, the inspection time can be reduced.

[0005] A preferred method of manufacturing a toilet according to the present invention is a method of manufacturing a toilet having a bent drainage channel below a ball surface and having a space surrounded by the drainage channel. A method of manufacturing a toilet bowl, comprising: providing a hole in a partition between a space other than a drainage channel adjacent to the space and communicating with outside air; By doing so, since the sintering is performed in a state where there is no closed space, damage due to air expansion during sintering is prevented.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a side sectional view of a toilet according to the present invention. The toilet 1 has a rim 2 and a ball surface 3 at an upper portion, and has a bent drainage channel 9 at a lower portion of the ball surface 3. The space 10 surrounded by the drainage channel 9
The space 1 is adjacent to the space 12 communicating with the outside air through the pressurized air supply hole 13 and the mud hole 14, and the partition 1 therebetween has the hole 1
1 is provided.

[0007] In the above-mentioned toilet bowl, for example, after casting the skeleton portion of the toilet bowl 1, a hole 11 is opened, and a separate molded body (laminated plate) is formed.
It can be obtained by baking after bonding 4, 5, and 6.

If there is a crack in the wall 5 of the toilet shown in FIG.
And leaks through the mud holes 14. Therefore, toilet 1
It is possible to confirm the presence of water leakage and trap air leakage only by water leakage inspection. Therefore, a conventional trap leak test is not required.

[0009]

According to the toilet of the present invention, it is possible to simultaneously perform the water leakage inspection and the trap air leakage inspection. Therefore, the inspection work time is shortened and the work efficiency is improved.
