Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating panel. More specifically, the present invention relates to a floor heating panel that is easy to manufacture and has a thin heater built-in throughout.

[0002]

2. Description of the Related Art Conventionally, as one of indoor heating systems, for example, a heater-embedded floor heating panel having a cross-sectional view shown in FIG. 5 is known. In the case of this floor heating panel (a), for example, a flat plate made of a steel plate or the like is placed inside a panel body composed of a surface layer material (b) having a surface makeup and a base material plywood (c) having excellent heat insulating properties. Built-in heating plate (d) and electric heater (e), and this heater (e)
An overheat prevention device (f), which is composed of, for example, a thermostat or a thermal fuse, is connected to the.

Of these, for the heater (e), for example, a resistance heating wire (g) such as a nichrome wire as shown in FIG. (2) A sheet-shaped heater coated with (2) is often used. Further, as shown in FIG. 7, an electrode (K) of an insulating sheet (K) having conductive electrodes (K) arranged at both ends.
In between, heating element such as carbon resin or carbon fiber
A surface heater having a structure in which both the upper and lower surfaces are coated with insulating films is also known.

[0004]

However, in the case of the conventional surface heater (e) as shown in FIG. 6, the resistance heating wire (g) wired in the insulating sheet (h) is connected to the power source or the adjacent side. In order to connect to another heater, for example, a lead wire (s) in which insulated wires with a diameter of 0.75 to 1.25 mm are twisted together is connected to both ends of the resistance heating wire (g). The work was extremely troublesome.

Further, in the case of the surface heater (e) illustrated in FIG. 7, it is necessary to provide a terminal box (se) for connecting the lead wires (s) to the electrodes (u) at both ends. The whole could not be formed flat.
The present invention has been made in view of the circumstances as described above, eliminates the drawbacks of the heater incorporated in the conventional floor heating panel, is thin and has a flat shape as a whole, and wiring connection is extremely easy. It aims to provide floor heating panels with new heaters.

[0006]

In order to solve the above problems, the present invention provides an insulating sheet having a resistance heating wire fixed to the wiring and a resistance heating wire provided at the end edge of the insulating sheet. Provided is a floor heating panel having a built-in sheet heater formed by coating a flat cable connecting both ends with insulating films from both upper and lower surfaces.

[0007]

In the heater built into the floor heating panel according to the present invention, a flat cable serving as a connection terminal for the resistance heating wire is previously arranged at the edge of the insulating sheet, and the resistance heating wire is fixed on the insulating sheet. At the same time, both ends are connected to the flat cable. Therefore, by finally covering the upper and lower surfaces with insulating films, it is possible to easily form a surface heater having a connection terminal for a resistance heating wire at the edge portion, and simplify the manufacturing process of the floor heating panel. .

Further, since the thin flat cable is used as the connection terminal, the entire heater can be formed flat. Therefore, it is possible to reduce the thickness of the floor heating panel.

EXAMPLES Examples will be shown below with reference to the accompanying drawings.
The floor heating panel of the present invention will be described in more detail. FIG. 1 is an exploded perspective view illustrating the configuration of a heater used in the floor heating panel of the present invention.

For example, this heater is composed of an insulating sheet (2) such as kraft paper in which a resistance heating wire (1) is patterned and an insulating film (3) covering both upper and lower surfaces of the insulating sheet (2). There is. Of these, the insulating sheet (2) has a sheet piece (5) provided with two flat cables (4) having exposed conductive surfaces, which extends at the edge of the insulating sheet (2). Both ends of the resistance heating wire (1) wired in the above are fixed so as to contact the surface of the flat cable (4).

The resistance heating wire (1) has, for example, a diameter of 0.
A Ni-Cr wire, a Cu-Ni wire or the like having a size of about 1 to 0.2 mm can be used, and a sewing machine is used as shown in FIGS. 2 (a) and 2 (b), respectively, which are side sectional views and plan views. For example, the pattern wiring can be performed while sewing the insulating sheet (2) with the thread (6). Also, resistance heating wire (1)
When connecting both ends of the to the flat cable (4),
For example, as shown in the perspective view of the main part of FIG. 3, the resistance heating wire (1) fitted on the flat cable (4) is used together with the flat cable (4) with the thread (6) to form the sheet piece (5). It can be sewn on and fixed.

As shown in FIG. 3, a flat cable (4) extending from the insulating sheet (2),
Since the resistance heating wire (1) connected to the flat cable (4) is covered on both upper and lower surfaces by the insulating film (3) like the resistance heating wire (1) on the insulating sheet (2), it is separately provided. No need to insulate. In this way, a planar heater having a connection terminal for the resistance heating wire (1) and having a flat overall surface is completed. In order to electrically connect the connection terminal of the planar heater to a power source or another adjacent heater, for example, a flat cable (4) is connected by an alligator connector (7) as shown in FIG. The flat cable (4) and the lead wire (8) can be connected to each other by penetrating the insulating film (3) on the surface of (1).

Of course, the present invention is not limited to the above examples, but the wiring pattern of the resistance heating line,
It goes without saying that various aspects are possible for details such as the connection method between the flat cable and the lead wire.

[0014]

As described in detail above, according to the present invention, it becomes possible to easily manufacture a sheet heater having a connecting terminal, and the sheet heater is thin and flat as a whole. Therefore, the degree of freedom in designing the thickness of the floor heating panel is increased.
