[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bathroom washroom with floor heating.
[0002]
[Prior art]
In the conventional bathroom washroom with floor heating, a grid-like reinforcing rib with a relatively high height is provided on the back of the washroom by SMC press molding to ensure strength, and a planar heater is laminated within the thickness of the washing scene. The structure was formed by integrally molding, electrically connecting the back surface, and then spraying a foamed resin.
[0003]

[0004]
[Problems to be solved by the invention]
However, in the washing scene, a three-dimensional shape such as a mortar is used to improve drainage, and a drainage gradient is always provided on the surface. In that case, the back surface is also a curved surface that is not a simple flat surface, and it is not easy to mount the planar heater because the surface to which the heater is attached is not flat. Further, it is necessary to form the heat insulating material in contact with the sheet heater in accordance with the shape. In addition, the washing area needs a suitable reinforcing rib configuration and reinforcing bar on the back side to ensure load resistance, the planar heater can not be installed unless it is divided into a plurality, and the heat insulating material must also have a shape corresponding to multiple surfaces However, there are problems such as an increase in the number of parts and the number of mold surfaces, which complicates manufacturing management and increases costs.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention has a configuration in which a sheet heater , a soft heat insulating material having elasticity, and a hard heat insulating material are sequentially disposed on a back surface corresponding to a heating surface of a bathroom washing place.
[0006]
According to the above invention, the flexibility of the planar heater and the elasticity of the soft heat insulating material enable the planar heater to be closely fixed to the back surface corresponding to the heating surface of the bathroom washing area, which is the non-planar heater mounting surface. In addition, the heat of the heater can be conducted to the warming surface of the bathroom.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION

[0008]
With the flexibility of the planar heater and the elasticity of the soft heat insulating material, the planar heater can be fixedly adhered to the back surface corresponding to the heating surface of the SMC molding bathroom washing area, which is the non-planar heater mounting surface, Can be transferred to the warming surface of the SMC molding bathroom wash area. In addition, even if the heater mounting surface is divided into a plurality of parts and the surface shapes are different from each other, the shape of the heat insulating material can be handled by a simple shape such as a sheet shape or a flat plate shape. It is possible to provide a washing place with floor heating at low cost because only a small amount is required.
[0009]
The invention according to claim 2 of the present invention has a configuration in which a planar heater, a soft heat insulating material, and a hard heat insulating material are pressure-bonded to the back surface of a washing place by using a fixing bracket and tightening a mounting screw.
[0010]

【Example】
(Example 1)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show an embodiment of a bathroom washing room with floor heating according to the present invention. Reference numeral 1 denotes a bathroom washing place formed by press-molding an SMC (sheet molding compound) comprising an unsaturated polyester resin, a filler and glass fibers. In such a bathroom washing place 1, since a user uses hot water in the washing place, a gradient is provided from the periphery toward the drain port 1a in order to improve drainage. The back surface of the bathroom washing area opposite to the heating surface 1b is divided into a plurality by a reinforcing rib 1c as shown in FIG. The reinforcing rib 1c is provided on the back surface of the washing place in order to secure strength such as bending of the washing place. A non-planar heater mounting surface 1d having a different shape depending on the flow gradient is formed on the back surface of the washing place. On each heater mounting surface 1d, a planar heater 2 in which a tubing heater having a diameter of 2 mm is fixed on a flexible aluminum foil is arranged. Each planar heater 2 and the thermostat 3 are connected in series and connected to a power supply wire 4. In addition, a soft heat insulating material 5 made of a soft polyester-based urethane foam sheet having a thickness of 2 mm is arranged below the planar heater 2, and is constituted by a hard heat insulating material 6 made of styrene foam.
[0012]
With such a configuration, the flexibility of the planar heater 2 and the elasticity of the soft heat insulating material 5 make it possible to form a planar surface on the back surface corresponding to the heating surface 1b of the SMC molded bathroom washing place, which is a non-planar heater mounting surface. The heater 2 can be adhered and fixed, and the heat of the heater can be conducted to the heating surface 1b of the SMC forming bathroom washing area.
[0013]
Further, the fixing member 7 is stacked on the above-described configuration, and is fixed to a boss provided on the back surface of the washing place with a mounting screw (not shown), so that the sheet heater 2, the soft heat insulating material 5, and the hard heat insulating material 6 are pressed against the back surface of the washing place. Configuration. As described above, when the fixing screw is tightened using the fixing bracket 7, the soft heat insulating material 5 is compressed, and the sheet heater 2 is pressed against the back surface of the washing place. Therefore, the sheet heater can be fixed to the back of the washing place without using a process such as bonding.
[0014]
It is desirable that the thickness of the soft heat insulating material 5 be equal to or greater than the diameter of the heater wire of the planar heater 2. Then, since the thickness of the soft heat insulating material 5 is equal to or larger than the diameter of the heater wire of the sheet heater 2, the unevenness due to the two heater wires of the sheet heater and the curved surface of the back of the washing place are absorbed, and the sheet heater 2 is securely placed on the back of the washing place. This has the advantage of being able to be crimped to the surface.
[0015]
Further, it is desirable that the soft heat insulating material 5 has a sheet shape and a thickness of 1 mm or more and 10 mm or less. If the thickness of the soft heat insulating material 5 is thinner than 1 mm, it becomes difficult to tightly fix the sheet heater to the back surface corresponding to the heating surface 1b of the SMC forming bathroom washing area, which is a non-planar heater mounting surface, and a gap is generated, which is preferable. Absent. Further, when the thickness exceeds 10 mm, the thickness becomes too large, which is not preferable. By setting the thickness to 1 mm or more and 10 mm or less in a sheet shape, workability is improved, and by giving a certain appropriate thickness, irregularities due to the heater wire are absorbed. The sheet heater 2 can be firmly pressed against the back of the washing place.
[0016]
It is preferable that the hard heat insulating material 6 has a block shape and a thickness of 5 mm or more and 50 mm or less. Actually, a hard heat insulating material 6 made of styrene foam resin is formed by injection molding using a mold having a thickness of 20 mm. In this way, by setting the appropriate thickness, the dissipation of heat from the planar heater 2 to the back of the washing area is suppressed, and the heat generated by the planar heater 2 can be efficiently transmitted to the warming surface of the washing area surface. .
[0017]
By adopting such a configuration, not only can material costs and assembling man-hours for realizing a bathroom washroom with floor heating be reduced, but not only can the use of parts reduce the die cost, but also the production management can be simplified. Greatly improve productivity.
[0018]
【The invention's effect】
As described above, the invention according to the first aspect of the present invention is based on the flexibility of the planar heater and the elasticity of the soft heat insulating material, and the non-planar heater mounting surface, which corresponds to the heating surface of the bathroom washing area, The planar heater can be tightly fixed, and the heat of the heater can be reliably transferred to the heating surface of the bathroom washing area. Therefore, material costs and man-hours for assembling can be reduced, and not only the cost of the mold can be reduced by sharing parts, but also there is an effect of greatly improving productivity such as facilitating manufacturing management.
[0019]
In the invention according to claim 2, when the fixing screw is tightened with the fixing bracket, the soft heat insulating material is compressed, and the sheet heater is pressed against the back surface of the washing place. Therefore, the sheet heater can be fixed to the back of the washing place without using a process such as bonding.
