Embodiment approach 1
[0048] (Structure of planar heater)
[0049] figure 1 It is a perspective view showing the planar heater 100 of Embodiment 1. FIG. figure 2 It is a sectional view showing the main body of the planar heater 100 . image 3 is an exploded cross-sectional view showing the original parts used to form the body. Figure 4 for will be as image 3 An exploded perspective view of a part of the main body forming part of the heating wire.
[0050] (Structure of planar heater)
[0051] The planar heater is, for example, a heater installed on the floor of a house. Such as figure 1 As shown, the planar heater includes a main body 100 and a regulator 101 provided on the main body 100 . The regulator 101 includes a controller (not shown) that controls the value and the like of a current passing through a heating wire 132d of a heating wire 132 to be described later. The regulator 101 is connected to a power line 102 to supply power from the power line 102 . As a result, electric curren...
Deformed example 1
[0111] In the above-described embodiment, the metal plate 121 and the heating unit 130 in which the heating wire 132 is attached to the holding plate 131 are separately provided. On the other hand, in Modification 1, heating unit 130 and metal plate 121 are integrally provided by attaching heater wire 132 to metal plate 121 . In this case, there is a concern that the metal plate 121 may be wrinkled by the heating wire 132 . However, by using the felt-like heat insulating board 140 in which the high-melting-point resin fiber and the low-melting-point resin fiber are mixed, the heating wire 132 is embedded in the heat insulating board 140 , so this concern is eliminated.
Deformed example 2）
[0113] In the above-described embodiment, one metal plate 121 is used as the metal plate 121 , but in the second modified example, a plurality of metal plates 121 are used as the metal plate 121 . For example, the size of the planar heater may be larger than the size of the supplied metal plate 121 . In this case, as Figure 10 As shown, two metal plates 121 are used as the metal plate 121 . An adhesive 122 mainly composed of a thermoplastic resin is coated on both surfaces of each metal plate 121 . The two metal plates 121 are arranged so as to spread over the necessary range of the planar heater. These metal plates 121 are arranged at intervals along the extending direction of the metal plates 121 so as not to overlap. The interval is, for example, 0 to 20 mm, preferably 5 to 10 mm. In addition, in Figure 10 In , the heating wire 132 arranged under the metal plate 121 and the holding plate 131 is shown by a dotted line. In addition, in Figure 10In the arrow A, the d...
