  By the way, in the three-part type toilet as described above, there is a problem in that it is difficult to stably support the bowl part for a long period of time when the bowl part is difficult to support from below.

  The present invention has been made to solve the above problems, and provides a toilet devised so that the bowl portion can be stably supported over a long period of time even if the bowl portion is difficult to support from below. It is intended to do.

  In order to solve the above-mentioned problems, the present invention is a toilet bowl divided into three parts: a skirt part, a bowl part arranged inside the skirt part, and a rim part joined to the upper part of the skirt part, A toilet bowl is provided in which a bowl support member having a bowl receiving portion along the back surface of the bowl portion is disposed inside the skirt portion.

  In order to further improve the impact resistance, the bowl support member is preferably made of metal.

  In order to reduce the weight of the entire toilet, the bowl support member is preferably hollow.

  In order to prevent freezing of residual water in the toilet in a cold region, it is preferable to supply hot water or store a heater in the hollow portion of the bowl support member.

  In order to attenuate a hit sound such as urine water, it is preferable that at least a part of the bowl support member is formed of a damping material.

  According to the present invention, since the back surface of the bowl portion is supported by the bowl receiving portion of the bowl support member arranged inside the skirt portion, the vertical impact load acting on the bowl portion and the horizontal impact load are The impact resistance to the skirt portion is improved, and the support of the bowl portion with respect to the skirt portion is stabilized, so that the positional deviation at the time of joining hardly occurs. Moreover, even if the toilet bowl design is difficult to support the bowl part from below, the bowl part can be stably supported over a long period of time by arbitrarily changing the shape of the bowl support member within the range that fits inside the skirt part. It becomes like this.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. Note that portions having the same configuration and operation as those of the background art are denoted by the same reference numerals, and detailed description thereof is omitted.

  1 (a) is a side sectional view of the toilet, FIG. 1 (b) is a perspective view of the bowl support member 6, FIG. 2 (a) is a plan sectional view of the skirt portion, and FIG. 2 (b) is FIG. 2 (a). FIG. 2C is a cross-sectional view taken along the line II-II of FIG. 2B.

  In FIG. 1A, the bowl portion 2 is disposed inside the skirt portion 1, and the rim portion 3 is joined to the upper portion of the skirt portion 1. The rim portion 3 is formed by an upper side portion 3a and an inner side portion 3b, and the upper end portion 1a of the skirt portion 1 is brought into contact with and joined to the lower surface of the upper side portion 3a of the rim portion 3, and the bowl portion 2 The upper end 2 a is joined to the bottom 3 c of the inner side 3 b of the rim 3.

  Inside the skirt portion 1, there is disposed a columnar-structured bowl support member 6 in which a bowl receiving portion 6 b is formed along the back surface 2 b of the bowl portion 2. The bowl support member 6 is placed on the toilet floor and is disposed in a U-shaped base portion 6a in a plan view and above the base portion 6a. The bowl support member 6 is shorter in length than the base portion 6a and has a plan view. The U-shaped bowl receiving portion 6b and a plurality of (in this example, five) columnar portions 6c that connect the base portion 6a and the bowl receiving portion 6b in the vertical direction. And the lower surface 2b of the bowl part 2 is supported by the bowl receiving part 6b by fitting the lower part of the bowl part 2 to the bowl receiving part 6b from above.

  Thus, by supporting the back surface 2b of the bowl part 2 with the bowl receiving part 6b of the bowl support member 6 disposed inside the skirt part 1, the vertical acting on the bowl part 2 as shown in FIG. The impact resistance against the horizontal impact load V and the horizontal impact load H is improved, and the support of the bowl portion 2 with respect to the skirt portion 1 is stabilized, so that positional displacement during joining is less likely to occur.

  Further, even if the toilet bowl design is difficult to support the bowl portion 2 from below, the bowl portion 2 can be extended over a long period of time by arbitrarily changing the shape of the bowl support member 6 within a range that can be accommodated in the skirt portion 1. It becomes possible to support stably.

  The bowl support member 6 may be made of a synthetic resin having a reinforcing fiber material, but if it is made of metal, the impact resistance is further improved.

  The bowl support member 6 may be a solid round bar joined, but if the pipe is joined, the entire toilet can be reduced in weight. Furthermore, if it is a pipe material, processing by a pipe bander etc. will become easy. In addition to a solid round bar or pipe material, a T-shaped material or an I-shaped material can be used.

  In this way, if the bowl support member 6 is a pipe material, as shown in FIG. 2B, the hot water tank 7 is connected to the bowl support member 6, so that hot water is supplied to the hollow portion of the bowl support member 6. By supplying, it becomes possible to prevent freezing of the residual water in the toilet in a cold region. Even if the heater is housed in the hollow portion of the bowl support member, the remaining water can be prevented from freezing in the same manner.

  Further, if the bowl receiving portion 6b of the bowl support member 6 (corresponding to at least a part of the bowl support member 6) is formed of a vibration damping material (eg, magnesium material), the rear of the surface (cleaning surface) of the bowl portion in particular. On the side, vibration of a portion that is particularly likely to be hit by male urine (see arrow a in FIG. 2B) is suppressed, and the hit sound can be attenuated.

  The bowl support member 6 does not need to be a separate body from the skirt portion 1, and can be integrated with the skirt portion 1 by insert molding in the skirt portion 1.

  3A is a plan view of a skirt portion according to another embodiment, FIG. 3B is a cross-sectional view taken along line III-III in FIG. 3A, and FIG. 3C is IV-IV in FIG. 3B. FIG. 3 is a cross-sectional view of a line, and as shown in FIGS. 3A and 3B, the outline and hatching are indicated by phantom lines, the bowl receiving portion 6 b of the bowl support member 6 has a substantially hemispherical shape along the back surface 2 b of the bowl portion 2. A damping material 8 is arranged. The damping material 8 does not need to be disposed on the entire surface on the back surface 2b side of the bowl portion 2, and is at least near the water storage surface (draft surface) L of the bowl portion, preferably below the water storage surface (draft surface) L. Arrange to position.

  Thus, by arranging the damping material 8 on the bowl receiving portion 6b of the bowl support member 6, the entire back surface of the bowl portion 2 can be supported by the damping material 8, so that the bowl portion 2 is supported by the bowl support member 6. Becomes more stable.

  Further, the vibration damping material 8 makes it possible to attenuate a hit sound in a portion where urine water or the like (see an arrow a in FIG. 3A) easily hits, particularly on the rear side of the surface (cleaning surface) of the bowl portion 2. .

  Furthermore, if the vibration damping material 8 is at least a water storage surface (draft surface) L or less of the bowl portion 2 so that the vibration damping material 8 has heat insulation (or heat insulation), the inside of the toilet in a cold region Residual water can be prevented from freezing.

  When the damping material 8 is made of, for example, a magnesium material (metal material), the impact resistance is further improved.

  Moreover, since the magnesium damping material 8 is molded by a thixo mold, it can be molded in a three-dimensional shape so as to be in close contact with the back surface 2b of the bowl portion 2 so that the damping performance is further improved. Become.

  In the embodiment, the toilet bowl is a synthetic resin molded product divided into at least three parts, a skirt part 1, a bowl part 2, and a rim part 3, and these are joined and integrated by welding. Examples of the molding method include injection molding, compression molding, and vacuum molding. As the molding material, relatively strong acrylic resin, ABS or PBT with a reinforcing material, or the like can be used. The bowl portion 2 can be made of earthenware or metal.
