Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a bathroom floor heating structure used for heating a bathroom floor.

[Prior Art] Conventionally, floor heating in a bathroom is mainly performed by a hot water method in which a pipe is buried in the floor and hot water is passed through the pipe to warm the pipe, or a heater wire method in which a heater wire is buried in the floor.

[Problem to be Solved by the Invention] In the above-mentioned conventional examples, since all of them are embedded in the bathroom floor, construction is troublesome and maintenance is difficult, and repair cannot be performed unless the floor surface is broken during repair. There is also a problem that the facility area cannot be changed.

The present invention has been devised in view of the above-described problems of the conventional example, and its purpose is to simplify the construction,
It can be retrofitted, and it can be freely installed at any position. Further, the maintainability is improved, and the heat insulating material and the heater can be prevented from being exposed to moisture. An object of the present invention is to provide a bathroom floor heating structure that does not cause any trouble and can be made thinner as a whole.

[Means for Solving the Problems] The bathroom floor heating structure of the present invention has a container-shaped synthetic resin case 5 whose whole periphery is surrounded by side walls and whose shallow bottom is open at the top.
A bathroom floor heating panel 3 in which a reinforcing plate member 6, a heat insulating material 7 made of a microporous body formed by molding fine particles, and a heat equalizing plate 9 provided with a heater 8 on the back surface are formed. The upper surface of the panel 3 is fixedly attached to the back surface of the waterproof floor pan 1 for washing by a fixing means from the rear surface side, and the back surface of the waterproof floor pan 1 for washing and a shallow container-like floor whose entire circumference is surrounded by side walls. And the case 5 covers the whole of the heat equalizing plate 9 provided with the reinforcing plate 6, the heat insulating material 7, and the heater 8 on the back surface. By adopting such a configuration, the object of the present invention described above. Is achieved.

[Operation] Since the bathroom floor heating panel 3 has the heat insulating material 7 provided on the back surface of the heater 8, the heat of the heater 8 is insulated by the heat insulating material 7 to prevent the heat from escaping downward. The reinforcing plate 6 enhances the strength of the floor heating panel 3. Since the heater 8, the heat insulating material 7, and the reinforcing plate 6 are housed in the case 5 made of synthetic resin, the heater 8, the heat insulating material 7, and the reinforcing plate 6 are not directly exposed to a relatively high humidity atmosphere under the floor of the bathroom. ing. Further, since the heat insulating material 7 is made of a microporous body formed by molding fine particles, the heat insulating material 7 has high heat insulating property and sufficient compressive strength, and thus can be made thinner. The whole can be made thin.

[Embodiments] The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

5 to 7 show an embodiment of the bathroom floor heating panel 3 according to the present invention. Container-shaped synthetic resin case 5 with a shallow bottom that is open at the top and surrounded by side walls.
Inside, a reinforcing plate member 6 formed of a moisture-resistant veneer plate or the like, a heat insulating material 7, a metal plate such as an aluminum plate provided with a heater 8 on the back surface, and a heat equalizing plate 9 formed of a ceramic plate or the like are laminated to form a bathroom floor heating panel 3. It is composed. The case 5 has a rectangular shape in a plan view, and has left and right side edges of the upper opening extending outward to form a mounting piece 10. The heat equalizing plate 9 is located at the upper opening of the case 5, and both right and left sides of the heat equalizing plate 9 extend so as to overlap the mounting piece 10, forming an extending portion 11. It is preferable that the heater 8 has a self-temperature control characteristic (the heater 8 may have a temperature control characteristic by being connected to a temperature control device). Examples of the type of the heater 8 include a linear heater and a planar heater. Particularly, a thin linear heater or a thin planar heater is preferable.

As the heat insulating material 7 used in the present invention, a fine porous body formed with fine particles is used. The fine porous body (inorganic porous body) formed with the fine particles is specifically as follows.

Examples of the fine particles forming the microporous body include fine particles of silica, a dried colloidal sol, aerogel, polysilicic acid by a dry method or a wet method, or those obtained by subjecting their surfaces to an aggregation preventing treatment.

It is preferable that the particle size of the fine particles (the particle size after the treatment after the aggregation prevention treatment) is in the range of 1 to 20 nm. Less than,
The fine particles in the range of 1 to 20 nm are appropriately referred to as “ultrafine particles A”.
That. The applicant has already proposed a microporous body using such ultrafine particles A in Japanese Patent Application No. 63-12826.

Agglomeration prevention treatment involves the OH of silanol groups on the particle surface.
It is preferable to prevent the occurrence of hydrogen bonding by bonding to the particles, to provide repulsion between particles, to directly prevent aggregation of particles, and the like.Specific examples include organic silane compounds, for example, Trimethyltoxylsilane, dimethyldiethoxysilane, alkoxysilane compounds such as methyltrimethoxysilane, chlorosilane compounds such as dimethyldichlorosilane, hexamethyldisilazane, silazane compounds such as dimethyltrimethylamine, but are not limited thereto. Absent.

Further, in addition to the ultrafine particles A, fine particles having an effect of improving moldability and preventing radiation (hereinafter, appropriately referred to as “fine particles B”) may be used together. The fine particles B have a primary particle size larger than that of the ultrafine particles A and a particle size of 20 to 10,000 n.
Those having a good m range and a large thermal emissivity, particularly those having a thermal emissivity of 0.8 or more in the infrared region having a wavelength of 3 μm or more are preferred.

The reason that the moldability is improved by using the fine particles B is considered to be that the ultrafine particles A and the fine particles B have a function of keeping the molding pressure uniform by dispersing and absorbing the molding pressure with each other. Can be

Specific examples of the fine particles B include finely pulverized pearlite and shirasu balloon, soot, cordierite, inorganic layered compounds such as clay, diatomaceous earth, calcium silicate,
Carbon _{black, SiC, TiO 2, ZrO,} CrO 2, Fe 3 O 4, Cu
Fine particles of S, CuO, MnO ₂ , SiO ₂ , Al ₂ O ₃ , CoO, Li ₂ O, CaO and the like can be mentioned.

You may shape | mold by adding a fiber further to a microparticle. The strength of the microporous body is increased, and the heat insulator becomes easier to handle.

Examples of the fibers to be added include inorganic fibers and organic fibers such as ceramic fibers, glass fibers, rock wool fibers, asbestos fibers, carbon fibers, and aramid fibers.

The amount of the fiber added is preferably 20% by weight or less based on the particle weight, and the diameter of the fiber is preferably 30 μm or less, more preferably 5 μm or less. The length of the fiber is preferably 50 mm or less.

Further, the molding pressure is preferably 5 kg / cm ² (there is no problem even if a person weighing 100 kg steps on). During molding, for example,
After putting in a bag, pressurize with a soaking plate with heater. When the microporous body is disposed in the pearlite without using a bag, it is preferable that a seal is provided to such an extent that the fine particles do not scatter outside.

In addition, high thermal efficiency (thinning), high density (can be trampled)
From this point of view, it is sufficient to increase the molding pressure of the microporous body of the heat insulating material to increase the density, but the increase in the density is accompanied by a deterioration in cost performance. That is, high thermal efficiency, high strength, and cost performance are in a trade-off relationship, and usually, conditions are set such that a proper balance can be obtained within a desired performance range.

However, since the heat insulating material having the above-described configuration uses a microporous body formed by forming fine particles, the heat insulating material maintains extremely excellent heat insulating properties at normal pressure without deterioration with time, so that the heat insulating material has a high thermal efficiency. It has a long-term heat supply effect. The microporous body can be easily formed to have a sufficient compressive strength by forming it under a certain pressure or more, so that there is no need for a large-scale reinforcing material, and the high thermal efficiency and sufficient compressive strength of such a heat insulating material are eliminated. Is to reduce the thickness. In addition, a microporous body using fine particles (or ultrafine particles) whose surface has been previously prevented from agglomeration has not only a narrower gap between the particles and better heat insulation, but also the above-described aggregation prevention treatment. Since it provides water repellency, it can maintain a stable heat insulating property even under high humidity and can be used as a heat insulating material for bathroom floor heating panels suitable for use under high humidity. The heating floor has no problem even under high humidity.

Thus, the bathroom floor heating panel 3 having the above-described configuration is used.
The bathroom floor heating panel 3 is fixed to the reinforcing wooden part 2 on the back surface of the washing floor waterproof pan 1 by fixing means 4 such as a screw, so that the back surface of the washing floor waterproof floor pan 1 is heated. Here, a reinforcing wooden part 2 such as water-resistant plywood is laminated on the back surface of the waterproof floor pan 1 for a washing place, and a reinforcing frame 11 is provided. The size of the bathroom floor heating panel 3 is surrounded by the reinforcing frame 11. Size slightly smaller than the size of the part
The fixing means 4 such as a screw is inserted from the mounting piece 10 into the reinforcing wooden part 2 by being arranged at an arbitrary position in a portion surrounded by 11. Therefore, the size of the bathroom floor heating panel 3 is, for example, about 35 cm in length and width. When the mounting piece 10 of the case 5 is fixed to the reinforcing wooden part 2 of the washing floor waterproof floor panel 1 by the fixing means 4, the heat equalizing plate 9 comes into contact with the reinforcing wooden part 2 and heat from the heater 8 is passed through the reinforcing wooden part 2. The floor is heated by transmitting it to the waterproof floor pan 1 for the washing area. When installing the bathroom floor heating panel 3, it may be attached to the back of the washing floor waterproof floor pan 1 when the washing floor waterproof floor pan 1 is installed, or after the washing floor waterproof floor pan 1 is installed. It may be attached to the back surface of the device 1 by retrofitting. In the case of this retrofitting, it is attached to the back of the waterproof floor pan 1 for a washing place by going under the floor. And panel 3 for bathroom floor heating
The maintenance, inspection, and the like are performed under the floor, and replacement can be easily performed by removing the fixing means 4.

1 and 2, reference numeral 12 denotes a bathroom unit, 13 denotes a bathtub, 14 denotes a bay window, and 15 denotes a leg having a height adjusting function for supporting the waterproof floor pan 1 for a washing place.

[Effect of the Invention] In the present invention, as described above, a reinforcing plate material, a heat insulating material, and a rear surface are provided in a container-shaped synthetic resin case having a shallow bottom and an open upper portion whose entire periphery is surrounded by side walls. A bathroom floor heating panel provided with a soaking plate provided with a heater is formed, and the upper surface of the bathroom floor heating panel is fixedly attached to the back surface of the waterproof floor pan for washing from the back side by a fixing means, and The floor of the bathroom floor is covered by the back surface of the waterproof floor pan for use and the container-like case with a shallow bottom surrounded by side walls, which covers the entire heating plate provided with a reinforcing plate, heat insulating material, and a heater on the back. By attaching a heating panel to an optional position on the back of the washing floor waterproof floor pan, an arbitrary portion of the washing floor waterproof floor pan can be heated to heat the floor. In particular, the upper surface of the bathroom floor heating panel is fixedly attached to the back surface of the washing floor waterproof floor pan from the back side by a fixing means, and the back surface of the washing floor waterproof floor pan and the bottom of the entire periphery are surrounded by side walls. With a shallow container-shaped case and the reinforcing plate, heat insulating material, and the entire soaking plate provided with a heater on the back, the entire surface of the soaking plate is equipped with a heater. The bathroom floor heating panel can be attached and detached, and since it is on the back side, the bathroom floor heating panel is not directly immersed in water despite the floor heating of the bathtub. In addition, since a heat insulating material is provided on the back surface of the heater, the heat of the heater is insulated by the heat insulating material to prevent the heat from escaping downward, and the reinforcing plate material enhances the strength of the floor heating panel. It is possible to further cover these heaters, heat insulating materials, and reinforcing plate materials by covering the entire surface with a back surface of a waterproof floor pan for a washing room and a container-like case with a shallow bottom surrounded by side walls.
It is not directly exposed to a relatively high-humidity atmosphere under the floor of a bathroom, and is prevented from being exposed to high humidity to cause deterioration or electric leakage, so that there is no problem even under high humidity.
Further, since the heat insulating material is made of a microporous body formed by molding fine particles, the heat insulating property is high and the compressive strength is sufficient. Panel can be made thinner.
