Embodiment approach 1

[0028] Structure of planar heater

[0029] Next, use Figure 1 to Figure 5 A planar heater according to an embodiment of the present invention will be described.

[0030] figure 1 It is a perspective view showing the appearance of the planar heater according to Embodiment 1 of the present invention. figure 2 It is a sectional view which shows the completed state of the main body of this planar heater. image 3 It is a sectional view disassembled and showing the details of the components of the main body. Figure 4 A plan view showing a heating unit of the planar heater. Figure 5 It is a schematic diagram which shows the detail of the heating line of this heating unit.

[0031] Such as figure 1 As shown, the planar heater 100 of this embodiment is composed of at least a main body 200, a controller 110, a power cord 111, and the like, and the main body 200 is composed of a plurality of sheet-shaped members. The controller 110 is disposed at one end of the main body 200...

Embodiment approach 2

[0093] Next, the configuration and manufacturing method of the planar heater according to Embodiment 2 of the present invention will be described. In addition, since the main body of the surface heater of this embodiment is the same as that of Embodiment 1, detailed description is abbreviate|omitted. That is, the manufacturing method of the main body of this embodiment differs from Embodiment 1. FIG.

[0094] Another manufacturing method of the main body of the planar heater

[0095] Next, use Figure 10 The manufacturing method of the planar heater of this Embodiment 2 is demonstrated.

[0096] Figure 10 It is a schematic diagram which shows the manufacturing process of the 1st laminated body in Embodiment 2 of this invention. in particular, Figure 10 It is a schematic diagram which shows the manufacturing process of bonding a back member and a heat insulating sheet, and manufacturing a 1st laminated body.

[0097] That is, in the manufacturing method of Embodiment 1...

Abstract

Provided are a planar heating device and a manufacturing method thereof. The planar heating device comprises a sheet-shaped back-surface part (240), a heat isolation sheet (230) which is laminated on the back-surface part, a heating unit (220) laminated on the heat isolation sheet (230) and a surface part (210) laminated on the heating unit (220). Bonding surfaces between the back-surface part (240), the heat isolation sheet (230), the heating unit (220) and the surface part (210) are bonded with bonding parts (250) which are mainly made of thermoplastic resin. At least one part of the bonding parts (250) form on the bonding surface in a discontinuous or nonuniform mode. Thus the planar heating device, of which unevenness on the surface is suppressed and appearance and performance are excellent, is realized.

Description

technical field [0001] The present invention relates to a planar heater formed by laminating a plurality of sheet members and a method for manufacturing the same. Background technique [0002] Conventionally, the main body of such a planar heater has been formed by laminating and integrating a sheet-shaped front member, a planar heating element, a heat insulating member, and a back member by bonding. For example, such a planar heater is disclosed in JP 2003-310416 A (hereinafter referred to as Patent Document 1). In addition, in Patent Document 1, the heat insulating member described above corresponds to a back surface member, and the back surface member corresponds to an anti-slip member. [0003] The main body of the planar heater in patent document 1 is manufactured as follows. [0004] First, on the hot plate on the lower side of the heat press, press the sheet-shaped back part, the third heat-welding part, the heat insulation part, the second heat-sealing part, the pl...
