It is sectional drawing which shows the structure of the 1st member used at the manufacturing process of the flush toilet concerning embodiment of this invention. It is sectional drawing which shows the structure of the 2nd member used at the manufacturing process of the flush toilet concerning the embodiment of this invention.

  Hereinafter, a plurality of embodiments of the present invention will be described with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same constituent elements in the drawings will be denoted by the same reference numerals as much as possible, and redundant description will be omitted.

  FIG. 1 is a simplified side sectional view of an entire flush toilet 1 according to an embodiment of the present invention. In FIG. 1, hatching is not shown.

  As shown in FIG. 1, the flush toilet 1 according to the embodiment of the present invention includes a first member 10, a second member 20, and an adhesive portion 30.

  The first member 10 includes a bowl 2 for excretion by a user, a trap 3 for forming accumulated water in the bowl 2, a rim 4 formed on the upper surface of the bowl 2 and abutting against a toilet seat on which the user sits, It is a part made of earthenware that has In the present embodiment, the rim 4 protrudes from the outer peripheral surface of the bowl 2 in the horizontal direction.

  The second member 20 is a part made of earthenware having a gutter 5 positioned below the rim 4 and covering at least a part of the bowl 2. In this embodiment, flush toilet 1 is a wall-fixed type. The bowl 5 covers the front and side surfaces of the bowl 2. The back surface of the bowl 2 is fixed by a wall and concealed, and the bottom surface of the bowl 2 is substantially concealed by being close to the floor, so that a bowl 5 is formed on the back surface side and the bottom surface side of the bowl 2. Absent.

  The bonding portion 30 is a portion where the first member 10 and the second member 20 are bonded.

  FIG. 2 is an enlarged view of the vicinity of the bonding portion 30 in the flush toilet 1 according to the embodiment of the present invention.

  As shown in FIG. 2, the bonding part 30 bonds, for example, the end of the first member 10 and the end of the second member 20. The bonding portion 30 is formed by loosely melting slurry of clay made of the same material as the first member 10 and the second member 20 with water. The adhesive part 30 is continuous with the first member 10 and the second member 20 in appearance, and is difficult to visually recognize. However, when the flush toilet 1 is cut up and down from the front to the rear, the bonding portion 30 is bonded to the bowl 2 side in the back direction from between the end of the first member 10 and the end of the second member 20. Since the protruding portion 30A from which the member protrudes is present entirely or partially, it can be visually recognized that the adhesive portion 30 is present. In addition, since the protrusion is inevitable, a portion where the protrusion protrudes must be prepared in shape.

  Next, the manufacturing method of the flush toilet 1 which concerns on embodiment of this invention is demonstrated.

  Since each structure of the flush toilet 1 is made of earthenware as described above, each shape is made by pouring clay called mud into a mold and dehydrating the part in contact with the mold. It is manufactured by drying a combination of the whole structure for a predetermined time and firing it.

Moreover, FIG. 4 is sectional drawing which shows the structure of the 2nd member 20 used at the manufacturing process of this embodiment. Note that hatching is omitted in FIGS. 3 and 4.

  In the method of manufacturing the flush toilet 1, the above-described bowl 2, the trap 3, and the rim 4 are integrally made of slurry and the first member 10 made of earthenware is obtained.

  Since a rim 4 as a border is formed around the bowl 2 opened to the user, the rigidity is high even in the pre-firing stage, and deformation due to handling thereof is difficult to occur. Moreover, since the wash performance as a toilet bowl is made by the bowl 2, the trap 3, and the rim 4, if the first member 10 is common, the flush toilet 1 can exhibit the same performance.

  In the present embodiment, the collar 5 as a design part that determines the appearance design is formed as the second member 20. That is, in the method for manufacturing the flush toilet 1, the step of obtaining the second member 20 made of earthenware is performed by making the basket 5 located below the rim 4 and covering at least a part of the bowl 2 with slurry. Note that the order of obtaining the first member 10 and obtaining the second member 20 may be reversed.

  Next, in the method for manufacturing the flush toilet 1, the first member 10 and the second member 20 obtained by manufacturing are bonded to obtain a molded product. Specifically, the first member 10 and the second member 20 are bonded below the rim 4 to form the overall shape of the flush toilet 1.

  Then, in the manufacturing method of flush toilet 1, the process of baking a molded article is performed.

  The flush toilet 1 is manufactured through the above steps.

  As a result, the part that produces performance as a toilet bowl is common (first member 10), and only the appearance (second member 20) can be changed, so that the development burden can be reduced and the production efficiency can be improved. Will have.

  As mentioned above, although embodiment of the technique which this application discloses was described, the technique which this application discloses is not limited above.

  For example, the first member 10 may include a configuration other than the bowl 2, the trap 3, and the rim 4, for example, a jet spout.
