Description

[Detailed description of the invention] [Field of industrial application] The present invention is for manufacturing a wall-mounted toilet by placing the back side of the toilet bowl on a firing table and firing it. This invention relates to a technique for preventing cracks from occurring at the joint between the rim part and the molded body.

[Conventional technology]

Typically, a wall-mounted toilet is installed with its back side in contact with a wall surface. In addition, for wall-mounted toilets, install the toilet bowl 1 as shown in Figures 4 and 5.
is manufactured. That is, first, the toilet main body 4 in which the toilet bowl 2 and the drainage passage 3, etc. are formed, and the rim part molded body 6 in which the rim passageway 5, etc. are formed are formed separately, and then the toilet main body 4 and the rim part are molded. The rim molded body 6 is bonded to the upper surface 4a of the toilet bowl body 4 using a paste adhesive made of the same material as the body 6. Then, these back surfaces 4b and 6b are placed on a firing table 7, and fired by passing through a tunnel furnace or the like to manufacture the toilet bowl 1.

[The problem that the idea aims to solve]

However, when placed on the baking table 7, the loads of the toilet bowl main body 4 and the rim molded body 6 are acting on their respective back surfaces 4b and 6b, and each of the back surfaces 4b and 6b is placed on the baking table 7. is in contact with.
Therefore, the contact frictional resistance between the firing table 7 and each of the back surfaces 4b and 6b acts to impede the behavior associated with thermal expansion and contraction during firing. As a result, the back surface 4b
The stress due to the behavior caused by the thermal expansion and contraction becomes concentrated at the joint 8 between the toilet main body 4 and the rim molded body 6, which is closer to 6b, and as shown in FIGS. 4 and 6, the joint 8 There was a drawback that cracks were generated in portion 8. Of course, a toilet bowl with cracks must be disposed of as a defective product, resulting in a decrease in yield.

[Means to solve the problem]

The present invention improves and eliminates the above-mentioned conventional problems, and aims to provide a wall-mounted toilet that does not generate cracks at the joint between the toilet main body and the rim molded body during firing. It is.

Therefore, the means adopted by the present invention to solve the above problem is to join a rim part molded body having a rim water passageway etc. formed thereon to the upper end surface side of the toilet bowl main body where a toilet bowl and a drainage passageway etc. are formed. In a wall-mounted toilet bowl that was fired by placing the back side on a firing table,
A protruding plate piece is provided on the back side of the toilet bowl body that contacts the baking table to prevent the back side of the rim molded body from coming into direct contact with the baking table, and the back side of the rim molded body is attached to the protruding plate piece. This is a wall-mounted toilet bowl characterized by being mounted and connected.

[Function] In the present invention, the joining of the toilet bowl body and the rim molded body is performed with the rim molded body placed on the protruding plate piece formed on the back side of the toilet bowl body that contacts the baking table. There is. Therefore, the load of the rim molded body comes to act on the protruding plate, and the behavior of the rim molded body due to thermal expansion and contraction is accompanied by the behavior of the toilet main body due to thermal expansion and contraction. As a result, no cracks will occur at the joint between the toilet bowl body and the molded rim portion.

〔Example〕

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

1 to 3 relate to one embodiment of the present invention, in which FIG. 1 is a partial sectional view showing the toilet bowl 11 placed on the baking table 7, and FIG. 2 is an exploded perspective view of the toilet bowl 11. FIG. 3 is a rear view of the toilet bowl 11. As shown in the figure, the toilet bowl 11 consists of a toilet bowl main body 14 in which a toilet bowl 12, a drainage passage 13, etc. are formed, and a rim part molded body 16 in which a rim passageway 15, etc. are formed. A rim molded body 16 is joined to the end surface 14a. This toilet structure is the same as the conventional one.

Therefore, the toilet bowl 11 of this embodiment has a toilet bowl main body 1.
4 and the rim part molded body 16 are placed on the firing table 17 as shown in FIG. It is formed on the back surface 14b side of the toilet main body 14. The protruding size of the protruding plate piece 19 may be such that most of the load of the rim molded body 16 is applied, and the protruding size may be such that the entire back surface 16b of the rim molded body 16 is placed on it. It may be hot.

Therefore, as shown in FIG. 1, when the toilet bowl body 14 and the rim molded body 16 are placed on the baking table 17, most of the load of the rim molded body 16 is applied to the protruding plate of the toilet bowl body 14. It comes to act on piece 19.
Therefore, the behavior of the rim molded body 16 due to thermal expansion and contraction during firing is performed integrally with the behavior of the toilet bowl body 14 due to thermal expansion and contraction.
Joint portion 18 between toilet bowl body 14 and rim molded body 16
stress is never concentrated on the In other words, it is possible to prevent cracks from forming in the joint portion 18.

By the way, the toilet bowl 11 of the above-mentioned embodiment has the following features for the purpose of simplifying construction workability and from the viewpoint of installation strength.
A pedestal 20 is formed in the lower part of the toilet main body 14 in contact with the floor of the toilet room so that it can stand on its own; however, the present invention is not limited to this embodiment. It may be a type toilet bowl. Of course, the shape, size, etc. of the toilet main body 14 and the rim molded body 16 can be changed as appropriate.

[Effect of idea]

As explained above, in the present invention, a protruding plate piece for placing the molded rim part is provided on the back side of the toilet bowl body that contacts the baking table, so that thermal expansion and contraction during baking is prevented. The behavior of the molded rim body becomes integral with the behavior accompanying the thermal expansion and contraction of the toilet bowl body, and stress is no longer concentrated at the joint between the toilet bowl body and the molded rim body. Therefore,
No cracks will occur in the joint. In other words, the occurrence of defective products can be significantly reduced, and the yield can be significantly improved.
