  However, each conventional toilet body has an increased production process, a problem in appearance, and a convenience in use according to the size is impaired.

  That is, in the toilet body disclosed in Patent Document 1, for example, the toilet body shown in FIG. 4, the outer wall 90 a is supported by the mounting wall 83 so that the top member 90 does not tilt toward the toilet bowl 2 due to the load during firing. Yes. For this reason, the outer wall 90 a is not joined to the outer peripheral wall 81, and a gap C is generated between the outer wall 90 a and the outer peripheral wall 81. For this reason, this toilet body must be provided with a hole for communicating the gap C to the outside so that the gap C expands and the outer peripheral wall 81 or the like is not damaged when the molded body is fired. In this case, the production process of the toilet body increases.

  Moreover, in this toilet bowl main body, since the mounting wall 83 is required and the inner surface by the side of the inner surface 90c of the inner surface 90c on the toilet bowl 80 side protrudes inwardly, the opening of the toilet bowl 80 is narrow. In this case, even if the toilet body is enlarged, the user feels inconvenient to use.

  Moreover, in the toilet bowl main body shown in FIG. 5, since the rim water passage 84 is formed inside the top member 91, the top member 91 becomes large and the outer wall 91a and the outer peripheral wall 81 can all be joined. Have difficulty. For this reason, it is easy to produce a hollow part between the outer side wall 91a and the outer peripheral wall 81, and there exists a possibility that this hollow part may expand | swell at the time of baking and the outer peripheral wall 81 may be damaged. Therefore, a gap C that communicates the hollow portion with the inner surface of the toilet bowl 80, for example, is necessary. In this case, the convenience at the time of use according to the size of the toilet bowl body is also impaired.

  On the other hand, in the toilet main bodies 92 and 93 shown in FIGS. 6 and 7, the joining line L between the main body material and the top member material is not near the upper end of the toilet main bodies 92 and 93, so that the appearance is further improved. Desired.

  The present invention has been made in view of the above-described conventional situation, and has an excellent appearance without increasing the production process, and is a pottery toilet body that can exhibit the convenience of use according to the size. Providing is an issue to be solved.

The pottery toilet body of the present invention has an outer peripheral wall placed on the floor,
A toilet bowl wall located in the outer peripheral wall and forming a toilet bowl;
In a ceramic toilet main body, comprising: an outer wall extending substantially vertically upward; and a ceiling member extending at least horizontally inward from the upper end of the outer wall, and a ceiling member joined to the upper end of the outer peripheral wall. ,
The top member has an attachment wall having an edge surface continuous with an upper surface of the top wall and an outer surface of the outer peripheral wall at an upper end of the outer wall,
The upper end of the outer peripheral wall consists of a horizontal joint surface that is substantially horizontal on the outside, and an inclined joint surface that is continuously inclined downward with the horizontal joint surface on the inside,
The mounting wall is formed with a horizontal bonded surface that is bonded to the horizontal bonded surface, and the outer wall is formed with an inclined bonded surface that is bonded to the inclined bonded surface.

  In the ceramic toilet body of the present invention, the inclined joined surface of the outer wall of the top member is joined to the inclined joined surface of the outer peripheral wall. Since the inclined joint surface has a downward slope continuously with the horizontal joint surface, the load of the top member during firing is not only due to the horizontal joint surface and the horizontal joint surface, but also by the slope joint surface and the slope joint surface. Is supported, and it is possible to prevent the top member from being inclined to the toilet bowl side.

  Moreover, in this toilet bowl main body, since the inclined joint surface of an outer peripheral wall and the inclined to-be-joined surface of the outer side wall in a top member are joined, a clearance gap does not arise between these. For this reason, this toilet body does not need to provide an extra hole separately, and does not increase the production process.

  Further, in this toilet body, the top member mounting wall has an edge surface that is continuous with the top surface of the top wall and the outer surface of the outer peripheral wall, and the joining line between the main body material and the top member material is not noticeable.

  Furthermore, in this toilet body, since there is no gap between the outer wall and the outer peripheral wall, the inner surface of the inner wall of the inner wall on the toilet bowl side does not protrude inward, and it is possible to secure a wide opening of the toilet bowl It is.

  Therefore, the pottery toilet body of the present invention exhibits an excellent appearance without increasing the production process, and can exhibit convenience during use according to the size.

  The top member only needs to have at least an outer wall, a ceiling wall, and a mounting wall, but the outer wall, the ceiling wall, an inner wall extending substantially vertically downward from the inner end of the ceiling wall, a mounting wall, The bottom wall extends substantially horizontally from the lower end of the inner wall and is connected to the outer wall. In this case, if the toilet body of the present invention is provided with a mounting wall that extends substantially horizontally between the upper part of the outer peripheral wall and the upper end of the toilet bowl wall, the lower surface of the bottom wall of the top member is the surface of the mounting wall. It is preferable to be joined to the upper surface. In this case, the load of the top member at the time of firing is supported also on the lower surface of the bottom wall and the upper surface of the mounting wall, and it is possible to further prevent the top member from being inclined to the toilet bowl side.

  Embodiments 1 and 2 embodying the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the ceramic toilet body 1 of the first embodiment has an outer peripheral wall 1 a placed on the floor surface F. Moreover, the toilet bowl wall 1b forms the toilet bowl 2, and the upper part of this toilet bowl wall 1b is penetrated by the single spout (not shown) opened in the circumferential direction of the toilet bowl 2. As shown in FIG. The front upper part of the toilet bowl wall 1b extends substantially horizontally forward and is integrated with the outer peripheral wall 1a to form a rim water passage 4. Further, the side and rear of the toilet bowl wall 1b are located in the outer peripheral wall 1a, the upper side part of the toilet bowl wall 1b extends substantially horizontally to the side, and the upper rear part of the toilet bowl wall 1b is substantially horizontally rearward. The rim water passage 4 is also extended. The toilet body 1 includes a top member 5 joined to the upper end of the outer peripheral wall 1a.

  The top member 5 includes an outer wall 5a extending substantially vertically upward, a top wall 5b extending substantially horizontally inward from the upper end of the outer wall 5a, and an inner wall 5c extending substantially vertically downward from the inner end of the top wall 5b. The bottom wall 5d extends substantially horizontally from the lower end of the inner wall 5c and is connected to the outer wall 5a. A mounting wall 5e having an edge surface 5f continuous with the upper surface of the top wall 5b and the outer surface of the outer peripheral wall 1a is provided outside the upper end of the outer wall 5a.

  As shown in FIG. 2, the upper end of the outer peripheral wall 1a is composed of a horizontal joint surface 1c that is substantially horizontal on the outer side and an inclined joint surface 1d that continuously slopes downward on the inner side with the horizontal joint surface 1c. Further, a horizontal bonded surface 5i bonded to the horizontal bonded surface 1c is formed on the mounting wall 5e, and an inclined bonded surface 5j bonded to the inclined bonded surface 1d is formed on the outer wall 5a.

  As shown in FIG. 1, the toilet body 1 has an inflow port 2 a formed at the lower end of the toilet bowl 2 communicating with an ascending flow path 2 b extending rearward on the back surface of the toilet bowl 2. The ascending flow path 2b extends to the toilet drain port 2d located at the highest position 2c higher than the inflow port 2a at the time of installation. A storage space 1g surrounded by an outer peripheral wall 1a and opened up and down is formed at the rear portion of the toilet body 1. The toilet drainage port 2d opens horizontally rearward toward the storage space 1g. In the storage space 1g, a drainage connection pipe 17 is connected to the toilet drainage port 2d via a packing (not shown), and the drainage connection pipe 17 is connected to a floor drainage pipe (not shown) raised on the floor surface F. ing.

  The toilet body 1 is manufactured as follows. First, a plurality of materials are formed by a waste mud casting method, and each material is subjected to processing such as cutting. One of the materials is a main body material that becomes the outer peripheral wall 1 a and the toilet bowl wall 1 b, and one of the other materials is a top member material that becomes the top member 5. And each raw material is joined and it is set as a molded object. Glaze is applied to the molded body to obtain a glazed product, and the glazed product is baked to obtain the toilet body 1.

  In the storage space 1g of the toilet main body 1 obtained in this way, the drainage connection pipe 17 and the toilet cleaning device 18 are stored. Further, a toilet seat and a toilet lid (not shown) are attached to the toilet body 1. Thus, a Western style flush toilet is constructed.

  In this Western style flush toilet, wash water is discharged from the toilet bowl cleaning device 18 into the toilet bowl 2. The washing water becomes a swirling flow in the toilet bowl 2 and is discharged together with the filth in the toilet bowl 2 through the inlet 2a, the rising channel 2b, the toilet drain port 2d, the drain connection pipe 17 and the floor drain pipe.

  Here, in the toilet body 1 of the first embodiment, as illustrated in FIG. 2, the inclined bonded surface 5j of the outer wall 5a of the top member 5 is bonded to the inclined bonded surface 1d of the outer peripheral wall 1a. Since the inclined joining surface 1d is continuously inclined downwardly with the horizontal joining surface 1c, the load on the top member 5 during firing is not only the horizontal joining surface 1c and the horizontal joined surface 5i but also the inclined joining surface 1d. And it is supported also by the to-be-joined surface 5j, and it can prevent the top member 5 inclining to the toilet bowl 2 side.

  Moreover, in this toilet body 1, since the inclined joint surface 1d of the outer peripheral wall 1a and the inclined joined surface 5j of the outer wall 5a of the top member 5 are joined, no gap is generated between them. For this reason, this toilet body 1 does not need to provide an extra hole separately, and does not increase the production process.

  Further, in the toilet body 1, the mounting wall 5e of the top member 5 has an edge surface 5f continuous with the upper surface of the top wall 5b and the outer surface of the outer peripheral wall 1a, and the joining line L between the main body material and the top member material is conspicuous. hard.

  That is, a horizontal step may inevitably occur between the top member material and the main body material. When the step is not near the upper end of the toilet body 1, the joining line L is noticeable. Moreover, such a level | step difference is hard to conceal by finishing and glaze. However, in the toilet main body 1, even if a horizontal step is generated between the top member material serving as the mounting wall 5e and the main body material serving as the outer peripheral wall 1a, the step is the upper end of the toilet main body 1. Since it is near, the joining line L is not conspicuous. The step can be easily eliminated by smoothly finishing the top surface of the top wall 5b in the top member material and the main body material. Further, since the step is continuous with the upper surface of the top wall 5b and the outer surface of the outer peripheral wall 1a, it is easily concealed by the glaze.

  Furthermore, in this toilet bowl body 1, since there is no gap between the outer wall 5a and the outer peripheral wall 1a, the inner surface on the toilet bowl 2 side of the inner wall 5c does not protrude inwardly, and the opening of the toilet bowl 2 is opened. It can be secured widely.

  Therefore, the toilet body 1 of the first embodiment can exhibit an excellent appearance without increasing the number of production steps, and can exhibit convenience in use according to the size.

  As shown in FIG. 3, the pottery toilet body 6 of the second embodiment is provided with a mounting wall 6g extending substantially horizontally between the upper part of the outer peripheral wall 6a and the upper part of the toilet bowl wall 6b. The toilet body 6 includes a top member 7 joined to the upper end of the outer peripheral wall 6a. The inside of the mounting wall 6g is a rim water passage 9 sandwiched between the upper surface of the toilet bowl wall 6b and the lower surface of the top member 7.

  The ceiling member 7 includes an outer wall 7a extending substantially vertically upward, a ceiling wall 7b extending substantially horizontally inward from the upper end of the outer wall 7a, and an inner wall 7c extending substantially vertically downward from the inner end of the ceiling wall 7b. The bottom wall 7d extends substantially horizontally from the lower end of the inner wall 7c and is connected to the outer wall 7a. A mounting wall 7e having an edge surface 7f continuous with the upper surface of the top wall 7b and the outer surface of the outer peripheral wall 6a is provided outside the upper end of the outer wall 7a.

  The upper end of the outer peripheral wall 6a is composed of a horizontal joint surface 6c that is substantially horizontal on the outside and an inclined joint surface 6d that continuously slopes downward with the horizontal joint surface 6c on the inside. The mounting wall 7e is formed with a horizontal bonded surface 7i bonded to the horizontal bonded surface 6c, and the outer wall 7a is formed with an inclined bonded surface 7j bonded to the inclined bonded surface 6d. Other configurations are the same as those of the first embodiment.

  In this toilet body 6, the lower surface of the bottom wall 7d of the top member 7 is joined to the upper surface of the placement wall 6g. For this reason, the load of the top member 7 at the time of baking is supported also in the lower surface of the bottom wall 7d, and the upper surface of the mounting wall 6g, and it can further prevent that the top member 7 inclines to the toilet bowl 2 side. Other functions and effects are the same as those of the first embodiment.

  In the above, the present invention has been described with reference to the first and second embodiments. However, the present invention is not limited to the first and second embodiments, and can be appropriately modified and applied without departing from the spirit of the present invention. Needless to say.

  For example, the top member can include an outer wall, a top wall, a mounting wall, and an inclined wall that extends downward from the inner end of the top wall and is connected to the outer wall. Also in this case, since the load of the ceiling member at the time of firing can be supported by the lower surface of the inclined wall and the upper surface of the mounting wall, as in the toilet bowl body 6 of Example 2, the ceiling member is inclined to the toilet bowl side. Can be further prevented.

  The present invention can be used for a Western style flush toilet.
