DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel-shaped electric heater and a drip-proof ceiling such as a bathroom provided with the panel-shaped electric heater.

[0002]

2. Description of the Related Art FIG. 5 shows an electric heating ceiling as a conventional example.

[0003] In the figure, an electric heating ceiling has four walls 20.
The heater wire 2 is placed on the underside of the ceiling plate 21 whose side is supported.
2, a sheet 23 made of aluminum vapor-deposited polyethylene or the like is spread, adhered to the ceiling with an adhesive 24, a heat insulating material 25 is provided thereon to keep the temperature, and the ceiling plate 20 is prevented from bending due to its own weight. The ceiling plate 20 is configured to be connected to a beam 27 by a suspension plate 26 and lifted.

Another conventional ceiling structure with an electric heater will be described with reference to FIG. Since the same parts as those in FIG. 5 are denoted by the same reference numerals, only the new parts will be described. Reference numeral 28 denotes a hard foam insulation material, and reference numeral 29 denotes a filling adhesive in an amount to fill a gap corresponding to the diameter of the heater wire.

[0005]

However, in the conventional structure shown in FIG. 5, the rigidity of the ceiling plate 21 is low.
The ceiling plate 21 is connected to the beam 27 by the suspension plate 26 and lifted to prevent the ceiling from hanging down, so that it is complicated and is not suitable for the ceiling of a unit bus requiring simple construction.

In the example shown in FIG. 6, the sheet 23 on which the ceiling plate 20 and the heater wire 22 are fixed is adhered with an adhesive 24, and the gap between the portions adjacent to the heater wire 22 is filled with a filling adhesive 29 while the sheet 23 is filled. And a hard foam insulation material 28 in a sandwich structure. And because the ceiling has rigidity, it is not necessary to lift the ceiling in connection with the beam in the ceiling area of about 1 tsubo to 1.5 tsubo, but the amount of the filling adhesive 29 used to finish the sandwich structure It is necessary to use an amount sufficient to fill the gap generated by the heater wire 22 having a diameter of 1 to 2.5 mm. Accordingly, there is a problem that the amount of the adhesive used becomes large and the cost increases, and the ceiling becomes heavy by the amount of the filling adhesive 29, making the work difficult. This problem is not limited to the ceiling, but also to a structure such as a side wall and a floor, or a structure such as a box, or a panel-like electric heater used for an electric heater.

The present invention solves the above-mentioned problems, and adopts an electric heating technique for an electric heating ceiling to increase the temperature of a panel-shaped electric heater or a bathroom ceiling to remove condensation water condensing on the panel-shaped electric heater or the ceiling surface. An object of the present invention is to form a panel-shaped electric heater or a drip-proof ceiling that dries promptly and inexpensively and firmly.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a brushed fabric having a panel-like electric heater or a heater wire attached to the entire back surface of a ceiling plate of a bathroom and having a bristle longer than the diameter of the heater wire. In addition, a hard foam material is provided on the raised cloth and integrated with an adhesive.

[0009]

According to the above construction, the surface plate or the ceiling plate and the heater wire are fixed in close contact with each other, and the rigid foam insulation is separated from the surface plate or the ceiling plate due to the presence of the heater wire, and a gap formed therebetween. In this case, since the adhesive is applied through the hairs of the raised fabric, a lightweight and rigid panel-shaped electric heater or ceiling can be obtained.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. (Example 1) In FIGS. 1 and 2, reference numeral 1 denotes a so-called PVC steel sheet in which polyvinyl chloride is adhered to a steel sheet or a ceiling plate having a resin surface such as an ABS resin plate, and 2 denotes a furano, tricot, nonwoven fabric, etc., with one surface brushed. The raised fabric 3 is a high density bristles (about 1.2 mm) longer than the diameter (about 1 mm) of the heater wire 4 provided on one side of the raised fabric 2. The raised fabric 2 is made of a material such as polyester or polyamide because the bristles have high elasticity. The heater wire 4 is fixed to the cloth 2 by sewing or the like.

Reference numeral 5 denotes a rigid independent foam heat insulating material such as expanded styrene or urethane foam; 6, an adhesive for bonding the surface of the ceiling plate 1 to the bristles 3 of the brushed fabric 2; 7, a non-brushed surface of the brushed fabric 2; Adhesive for bonding to rigid closed-cell foam insulation.

Reference numeral 8 denotes a gap formed between the ceiling plate 1 and the raised fabric 2 due to the presence of the heater wire 4.

Using the materials described above, an adhesive 6 is applied to the back side of the ceiling plate 1 and the brushed cloth 2 with the heater wire 4 thereon is directed to the heater wire 4 and the bristles 3 toward the ceiling plate 1. Then, the rigid foamed heat-insulating material 5 coated with the adhesive 7 is superposed on the brushed cloth 2 and is cured by pressure and adhered.

In the above configuration, the heater wire 4 and the brushed fabric 2 are interposed between the ceiling plate 1 and the rigid foam insulating material 5, and adhesives 6 and 7 are applied to the surfaces of the ceiling plate 1 and the rigid foam insulating material 5. At the time of applying and superimposing and pressing, the heater wire 4 is pressure-bonded between the ceiling plate 1 and the rigid foam insulation material 5 and, at the same time, provided on the brushed fabric 2 and longer than the diameter of the heater wire 4. The bristles 3 having high elasticity have a function of bending under pressure and penetrating into the adhesive 6 on the surface of the ceiling plate 1, and the bristles 3 have a wedge effect and an effect of strong bonding.

The bristle 3, which fills the gap 8 at a high density, has a function of bonding the ceiling plate 1 and the hard foam insulation material 5 at a very high density in a point-like manner. Since the bristle 3 supports the stress as a distributed load, the bristle 3 is high in rigidity and robust, and unlike the conventional example shown in FIG.
Since the inside is not filled with adhesive, a lightweight drip-proof ceiling can be constructed.

Further, when the brushed cloth 2 is sewn and fixed to the brushed cloth 2 with the sewing machine, the bristles 3 easily fall down immediately below the heater wire 4 and do not hinder the sewing of the sewing machine. Since there is a self-supporting action in a place where there is no heater, the heater wire 4 can be sewn with a necessary heater pattern on the drip-proof ceiling. (Embodiment 2) FIG. 3 shows another embodiment, in which the surface of the bristle 3 on one side of the brushed fabric 2 faces the hard foam insulation material 5, and the ceiling plate 1 and the brushed fabric are arranged. 2 is adhered with an adhesive 6, and a heater structure 4, bristles 3 on one side of the raised fabric 2, and a hard foamed heat insulating material 5 are superimposed on the heater wire 4, and a sandwich structure is formed by bonding with an adhesive 7. According to this embodiment, when the ceiling plate 1, the brushed fabric 2 and the rigid foam insulating material 5 are overlapped and bonded by pressure, the tips of the bristles 3 of the brushed fabric 2 are formed by the elasticity of the bristle 3. It has the effect of bending and entering the adhesive 7 applied to the surface, and the same strength as the internal cells near the surface of the rigid foam insulation 5 can be obtained between the rigid foam insulation 5 and the raised fabric 2. Has an effect of completely bonding between the ceiling plate 1 and the brushed fabric 2 by the adhesive 6, so that when an abnormal external force is applied, the hard foam insulation material 5 and the bristles 3 are separated. As a result, the brushed fabric 2 provided with the heater wire 4 does not peel off from the ceiling plate 1 and has an effect of maintaining the effect of fixing the heater wire and preventing the occurrence of overheating.

(Embodiment 3) FIG. 4 shows another embodiment, in which the diameter of the heater wire 4 is as large as about 2.5 mm, and hairs having a length of 2.5 mm or more are required to fill the gap 8. This is an effective example. The double-sided brushed fabric 9 is a double-sided brushed fabric having bristles 10 and 11 on both sides thereof. The length of the bristles 10 and 11 on both sides is about 1.5 mm, and the total length of the bristles is longer than the diameter of the heater wire 4. I have.

A sandwich structure is formed by bonding the ceiling plate 1, the heater wire 4, the double-sided brushed fabric 9, and the hard foam insulation material 5 with adhesives 6, 7.

According to the configuration of this embodiment, the gap 8 between the heater wires 4 is divided and filled with the bristles 10 and 11 on both sides of the double-faced raised fabric 9. The bristles 10 have a function of penetrating into the adhesive 7 on the surface of the rigid foam insulating material 5 due to their elasticity, and the bristles 11 also have an effect of penetrating into the adhesive 6 on the surface of the ceiling plate 1 due to their elasticity. This has the effect of reducing the elasticity of the hair and preventing the hair from collapsing, thereby obtaining a strong adhesive force.

[0020]

As described above, according to the panel-shaped electric heater and the drip-proof ceiling structure having the panel-shaped electric heater of the present invention, the following effects can be obtained. (1) Since the heater wire is sewn to the brushed fabric and fixed, the bristles of the brushed fabric do not hinder the sewing of the heater wire. There is an effect that can be obtained. (2) A gap created by the thickness of the heater wire, which becomes an obstacle when a heater wire is interposed between the hard surface plate or the ceiling plate and the hard foam insulation material to form an integrally bonded structure, is filled with hair of the brushed fabric. In addition, the elastic force of the bristles allows the bristles to enter into the adhesive, thereby enabling innumerable dot-like bonding with a wedge effect, so that a strong bonding force is obtained. (3) When a heater wire is interposed between the surface plate or the ceiling plate and the rigid foam insulation material to form an integrally bonded structure, a gap generated adjacent to the heater wire is not filled with the adhesive, and thus the amount of the adhesive is It is lightweight and strong due to the point-like adhesion of hairs even if the amount is small. (4) When the bristles of the brushed fabric are directed to the surface plate or the ceiling side, the air layer between the bristles serves as a heat insulating layer and has an effect of increasing the heat retaining effect. (5) Turn the hair of the one-sided brushed fabric toward the hard foam insulation,
When the heater layer is sewn on the non-raised surface of the raised fabric 2 and bonded to the surface plate or the ceiling plate, the adhesive force between the hair and the rigid foamed heat insulating material is the same as the strength of the cells on the surface of the rigid foamed heat insulating material. To the extent, the adhesive strength between the non-brushed side of the brushed fabric and the surface plate or ceiling plate can be strengthened by full-surface bonding, and even if the hard foam insulation is damaged due to abnormal external force, the heater wire will not It is firmly held on the surface board or ceiling board with brushed fabric,
This has the effect of preventing the occurrence of overheating accident due to the movement of the heater wire. (6) Although the present invention has been described with reference to the example of the drip-proof ceiling for the unit bath, the present invention can be widely applied to a panel-shaped electric heating appliance.
