Problems solved by technology

[0003] However, in this method, heating is performed from the outside of the laminated body, so there is a problem that in order to sufficiently melt the adhesive between the layers, it is necessary to overheat the surface layer material or the bottom layer material located outside it.
In particular, the surface heaters installed on the ground are generally produced in various sizes, so the cost of making molds increases, and it is difficult to replace the molds when producing surface heaters of different shapes or sizes. Increase productivity

Embodiment approach 1

[0078] [structure of planar heater]

[0079] refer to figure 1 An example of a representative structure of the planar heater 1 of the present invention will be specifically described. figure 1 It is a block diagram showing an example of the configuration of the planar heater 1 according to Embodiment 1 of the present invention.

[0080] The planar heater 1 has the surface material 200, the heating unit 400, and the heat insulation board 500, and is formed by laminating them.

[0081] The surface material 200 is a plate-shaped member constituting the surface of the planar heater 1 , and is disposed on the uppermost side of the planar heater 1 .

[0082] The heating unit 400 is a plate-shaped member having a vapor chamber 410 and a heating wire 420 , and is arranged below the surface material 200 .

[0083] The heating wire 420 is an electrical wire that receives power from the outside via a power cord (not shown) or the like to generate heat. The heating wire 420 is arran...

Figure 6 is showing Figure 5 It is a perspective view of an example of the specific structure of the heater wire which the main body has shown.

[0090] Such as figure 2 As shown, the planar heater 1 has a main body 100 composed of a plurality of plate-shaped members, and a...

Embodiment approach 3

[0188] In the above-described embodiment, at least one excitation coil is used in the heating step. It is preferable to use a plurality of excitation coils, and it is more preferable to arrange a plurality of excitation coils adjacent to each other at a position facing the laminated body. However, the structure in which a plurality of excitation coils are adjacently arranged is not particularly limited, and various arrangements can be employed. In addition, a structure different from that of the pressing roller 730 may be employed as the pressing portion. In Embodiment 3, an example of an adjacent arrangement structure of exciting coils and another structure of a pressing portion will be specifically described with reference to the drawings.

[0189] [Structure of Exciting Coil and Roller Unit]

[0190] In this embodiment, three exciting coils are provided in the heating step, and a roller unit capable of securing a longer pressing time is used as the pressing unit. Therefor...

Abstract

The invention provides a surface-shaped heater and a production method, a production device thereof. By using the invention, the surface of the surface material (200) can not be affected by heating, and the die is not required, besides, even the material in different sizes and shapes, the heater can still be produced. The surface-shaped heater is provided with the surface material (200) used to build the surface of the surface-shaped heater, a heating unit (400) provided with a heating wire (420) and a heat distribution plate (410) capable of emitting the heat energy and spreading to the surface material (200), a heat insulation plate (500) capable of preventing the heat generated by the heating unit (400) from transferring to the back surface side of the surface-shaped heater. The heat distribution plate (410) is provided with a metal plate (411) and a first bonding layer (412a) and a second bonding layer (412b), which are disposed on two surfaces of the metal plate (411) and are provided with heat plastic resin.

Description

technical field [0001] The present invention relates to a planar heater using an electric heater as a heat source, a manufacturing method and a manufacturing device thereof. Background technique [0002] Conventionally, such a planar heater has a structure in which three layers of a base material, a heating unit having a heating wire disposed on a base material, and a surface material are laminated. The base material and the heating unit and the heating unit and the surface material are pasted together by an adhesive. In this method of manufacturing a planar heater, an adhesive is applied to one main surface of the base material or heating element, and an adhesive is applied to the other main surface of the heating element or the surface material, and then, A layered body is formed by superimposing the base material, the heating unit, and the surface material. Then, the laminate is heated from the outside to melt the adhesive between the layers, and then press-molded using...
