  EMBODIMENT OF THE INVENTION The form for implementing the heat insulation bathtub which concerns on this invention is demonstrated below based on an Example with reference to drawings.

Example 1
Embodiment 1 of the heat insulating bathtub according to the present invention and its modification will be described with reference to FIGS. 1 to 5. In this specification, assuming that the heat insulating tub is installed in a bathroom, the front side is the front side, the back side is the rear side, and the left and right sides are the left and right sides when the heat insulation tub is viewed from the front of the bathroom. As shown in FIG. 4A, the heat insulation bath 1 of the present invention includes a bath 2, a heat insulation material 3, and a heat insulation material fixing means 4.

  The bathtub 2 is formed of, for example, a material such as a synthetic resin material, steel, ceramic or the like, and includes a side surface 7 and a bottom surface 8 as shown in FIG. 1 (a). The side surface portion 7 of the bathtub 2 is a portion that constitutes the peripheral wall of the bathtub 2, and includes a front side surface and a rear side surface of a long side, and a left side surface and a right side surface of a short side.

  The bottom portion 8 of the bathtub 2 is provided with legs 11 at appropriate positions on its lower surface (near four corners in the first embodiment). As shown in FIG. 1 (b), the leg portion 11 of the first embodiment is a joint that couples the base 12, a pair of legs 13 radially from the base 12 toward the radial direction from the center of the bathtub 2, and a pair of legs 13. And 14.

  In the first embodiment, the leg 11 is formed integrally with the bath 2, but the leg 11 is formed separately from the bath 2, and the adhesive, screw, and the like are formed on the bottom 8 of the bath 2. It may attach by a fixing means, such as. Alternatively, asperities may be formed on the bottom surface portion 8 and the leg portion 11 of the bath 2, and they may be attached as a configuration that can be elastically deformed and engaged with each other. Thus, the leg 11 is separately formed, and the timing of attaching to the bath 2 may be before (or including the manufacturing stage of the bath) or after the heat insulating material 3 is coated on the bath 2.

  The bathtub 2 is provided with the flange part 17 extended substantially horizontally to the outward of the bathtub 2 from the upper end of the side part 7, as shown to Fig.1 (a). In the first embodiment, as one of the heat insulating material fixing means 4, the heat insulating material holding rib 4-1 is formed in a protruding shape depending on the flange portion 17. Although it is desirable to form the heat insulating material holding rib 4-1 through the entire circumference at the flange portion 17 of the bath 2, if it is difficult to form the entire circumference due to the relationship with other members or forming reasons, It may be formed intermittently.

  An upper end portion of the heat insulating material 3 is inserted between the upper end of the side surface portion 7 of the bath 2 and the heat insulating material holding rib 4-1, and is fixed to the outside of the bath 2. Further, the upper end portion of the heat insulating material 3 may be fixed so as to pierce (cut into) the holding heat insulating material rib 4-1.

  In addition, when it is difficult to provide the holding heat insulating material rib 4-1 in the flange part 17, it is good also as another structure. For example, although not shown in the drawings, a rectangle or a heat retaining member is positioned outside the upper edge of the heat insulating material 3 along the circumferential portion to which the upper edge of the heat insulating material 3 in the lower surface of the flange portion 17 of the bath 2 abuts. It is good also as composition provided with multiple projection parts which have a curved surface which contacts material 3, going to the bottom.

As shown in FIG. 1, crank-shaped (wedge-shaped) joint surfaces 26 are formed at the places to be connected.

  As shown in FIG. 2A, the heat insulating material 23 for the bottom surface of the heat insulating material 3 is cut away at a location corresponding to the leg portion 11 of the bathtub 2 to form a notch 29. The leg portion 11 can project downward from the heat insulating material 23 for the bottom surface of the heat insulating material 3 through the notch 29 when it is covered from below.

  As shown in FIGS. 3 (a) and 3 (b), the front and rear side wall surface heat insulating materials 24 and the left and right side wall surface heat insulating materials 25 are fitted with the upper end of the bottom surface heat insulating material 23, respectively. A crank-like (鉤 -shaped) fitting surface 30 is formed to fit. On the other hand, at the upper end portion of the bottom surface heat insulating material 23, a crank-like (wedge-shaped) fitting surface 31 is formed so as to engage with the lower end portion of the wall surface heat insulating material 22.

  With such a configuration, the lower end portion of the wall surface heat insulating material 22 and the upper end portion of the bottom surface heat insulating material 23 are fitted, as shown in FIGS. 3 (a) and 3 (b). The material 22 and the heat retention material 23 for the bottom face are fitted, and the bottom face 8 of the bathtub 2 is assembled so as to cover the bottom from below.

It is supported and fixed from below by the fixing member 18.

  As shown in FIGS. 2 (a) and 3 (a), a plurality of heat-retaining material self-supporting legs 34 are provided on the lower surface of the heat-retaining material 23 for the bottom of the heat-retaining material 3. The heat insulating free standing leg portion 34 is formed to project downward from the lower surface of the heat insulating material 23 for the bottom surface of the heat insulating material 3.

  The downward projecting length of the heat insulating free standing leg 34 may be such that the lower surface of the heat insulating free standing leg 34 is substantially the same as or slightly higher than the lower surface of the leg 11 of the bathtub 2. The heat insulating free standing leg portion 34 may be formed integrally with the heat insulating material 23 for the bottom, or may be separately formed and fixed later.
