Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a perspective view of a bathroom in which a seating portion according to Embodiment 1 of the present invention is provided on a counter. Reference numeral 11 denotes a bathroom, which includes a bathtub 12, a base material counter 13, a washing place 14, and a wall 15. Further, the counter 13 is formed from the upper surface of the bathtub 12 to the washing place 14 via the groove-shaped drainage part 16 and has a height of 3 from the floor of the washing place 14.
It is provided along the wall 15 at a height of 50 to 550 mm, and the cushioning material 17 is detachably attached to the upper surface of the counter 13 by fitting the respective irregularities.

When taking a bath in this bathroom, a bather sits on a cushion member 17 attached to a counter 13 to wash his body. When the body is washed in such a posture, it is not necessary to take a forcibly bent position, and it is possible to sit comfortably, and it is possible to perform the showering operation easily and safely. A sufficient space for performing these operations is secured around the cushion member 17. Bathers,
I will sit with the buttocks in contact with the cushioning material 17,
It has a cushioning property, so it is comfortable to sit on and cushioning material 17 is provided by providing a heating means (not shown).
The surface of the cushion member 17 can be seated on the surface of the cushion material 17 without feeling cold even in winter or the like because the surface of the cushion member can be warmed.

FIG. 2 is a cross-sectional view of the cushioning member 17.
Reference numeral 18 denotes an elastic resin layer, and 19 denotes a heat transfer layer having good heat conductivity. Epidermis 20
First, a paint in which a large amount of aluminum powder having good heat conductivity is mixed is applied to the inside of the resin layer 18 formed in a bag shape,
Urethane foam 21 which is an elastic material is injected into the inside. A concave portion 22 is formed on the back surface, and is removably fitted to the convex portion 23 provided on the counter 13 to prevent displacement when sitting. Reference numeral 24 denotes an electric heater as a heating means, which is provided on the surface side of the counter 13 and has a heat insulating layer 2.
The structure of 5 prevents heat conduction to the back side.

When the power is turned on by operating a switch (not shown), the electric heater 24 is heated to warm the surface of the counter 13. At this time, as described above, since the structure is such that heat conduction to the back side is prevented by the heat insulating layer 25, there is almost no dispersion of heat to the lower side of the counter 13. Only the lower side of the cushion 17 is heated by the heat from the electric heater 24, but since the heat transfer layer 19 is provided, the heat is
9 to quickly warm the upper side, which is the seating surface. Without the heat transfer layer 19, the elastic material or the urethane foam 21 functions as a heat insulating material, and it is difficult to conduct heat. Therefore, the seating surface is not heated until a long time has elapsed since the power was turned on.

The resin layer 18 can be formed into a bag-like skin by rotation molding in which a mold is rotated to perform molding or blow molding. As the elastic resin, a soft PVC resin or a polyolefin-based, polyurethane-based, or polystyrene-based elastomer can be used.

As described above, the heat transfer layer 19 may be formed by coating the inside of the bag with a gun. Alternatively, the heat transfer layer 19 may be formed by enclosing an appropriate amount of paint and rotating the paint. In blow molding, extrusion molding, or the like, two layers of heat conductive resin having good thermal conductivity may be extruded and formed inside.

The thickness of the heat transfer layer 19 can be changed without a sense of incongruity due to the elasticity of the urethane foam 21.
The thickness of the resin layer is desirably 2 mm or less, and the thickness of the resin layer is desirably about 0.3 to 3 mm in consideration of heat conduction and durability.

As the heating means, an electric heating means using a sheet heater or a heater wire, a heating means using a heat storage material, or the like can be used as appropriate.

The elastic material 21 is described as a soft foamed polyurethane, but other resin foams, gel-like rubber materials, and the like can be used. In particular, when soft foamed polyurethane is used, the cushioning property is excellent, and the skin 1
8, foamed and filled inside.

With such a structure, the skin 2
0 and the elastic material 21 can be made of different materials, and by using a waterproof material for the skin, it is possible to use a material having poor water resistance as the elastic material, and use a foam material or the like as the elastic material. Even so, the appearance, touch, and feeling of use can be improved. Also, despite being detachable, the heat transfer layer 1
Because of the presence of 9, the heat from the heating means 24 of the base material can be quickly transmitted to the seating surface, and even if an elastic material having slow heat conduction is generally used, there is no need for a waiting time from the start of heating to the start of use. In addition, by having the heat transfer layer 19, it is possible to adopt a configuration in which the heating means is not provided on the cushion material,
The cushion material can be detached, and maintenance such as cleaning can be easily performed.

The elastic member can be easily waterproofed by joining a seal member to the opening, and since water is not absorbed into the inside, it is not necessary to consider the water resistance of the elastic member, and the durability can be improved.

(Embodiment 2) FIG. 2 shows a structure in which the cushion material is formed in a bag-like shape and then an elastic material is injected. As shown in FIG. 3, a resin layer and a heat transfer layer have a two-layer structure in advance. It is also possible to adopt a configuration in which the above-mentioned sheet is used as a skin, an elastic material is sandwiched by the heat transfer layer as an enclosing side, press forming is performed, a product shape is formed, and resin layers of upper and lower skins are thermally welded.

FIG. 4 is a schematic view of the present embodiment during molding. The skin 26 has a configuration in which a resin layer 27 and a heat transfer layer 28 are heat-welded or bonded to each other to form a two-layer sheet in advance.
Press molding is carried out by sandwiching a sheet of foamed polyethylene 29 which is an elastic material so that the outer skin 26 has the resin layer on the outer package side. If necessary, an adhesive is applied to the joint surface between the heat transfer layer 28 and the polyethylene foam 29.

In this way, the upper and lower skins are heat-welded simultaneously with the shaping of the shape, so that the elastic material can be waterproofed with a minimum amount of work, and since water is not absorbed inside, there is no need to consider the water resistance of the elastic material. Durability can be improved, and reliability can be improved because of thermal welding.

In this embodiment, the elastic material is foamed polyethylene. However, any thermoplastic resin such as foamed PP or urethane foam can be thermally welded, and the same effect can be obtained.

(Embodiment 3) The description of the same parts as in Embodiment 2 is omitted. The difference from the second embodiment is that, as shown in FIGS.
0 is provided, and the counter 31 is further provided with a drain groove 32. The drain groove 32 is provided with a gradient so that water does not stay, and the water dropped from the hole 30 flows to the front surface of the counter 31 or the drain part.

By adopting the structure of this embodiment, the skin 2
Since the area of the heat transfer layer 28 that joins the front and back surfaces of No. 0 increases, the seat can be heated more quickly. Further, since the hole 30 is provided at the lowest position of the seating surface or at a place where water easily accumulates when the user sits, the hole 30 can be used without discomfort to the user, and the water does not accumulate. The amount of heat for warming can be reduced.

Although the number of holes is plural, the number of holes may be one if heat conduction and drainage can be performed efficiently.
