Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a surface heating device for heating a human body, such as an electric carpet or an electric blanket.

[0002]

[Prior art]

 As shown in FIG. 3, the sheet heating device manufactured by wiring the heating wire and the heat-sensitive wire to the main body such as an electric carpet or an electric blanket is attached to the edge of the main body 1 to control the temperature of the heating wire 2. The terminal portions 5 of the heat generating wire 2 and the heat sensitive wire 3 are soldered inside the controller 4 for performing the above. More specifically, the heating wire 2a of the heating wire 2 shown in FIG. 4 and the terminal portion of the abnormality detection wire 2b, and the primary temperature sensor 3a and the terminal portion of the secondary temperature sensor 3b of the heat-sensitive wire 3 shown in FIG. As shown, the terminal fittings 8a and 8b were soldered 9a and 9b, respectively.

However, since the windings of the heat generating wire 2 and the heat sensitive wire 3 are relatively thin, if an external force is applied to the soldered terminal portion due to some impact during use, there is a problem that the wire is disconnected and cannot be used. was there. In order to deal with such a problem, as shown in FIG. 2, a meandering repair spare portion 10 ... Is formed near the controller 4 on the main body 1 side of the heat generating wire 2 and the heat sensitive wire 3. Every other time, the heat-insulating material at any of the cutting positions A to E corresponding to the heat-generating wire 2 or the heat-sensitive wire 3 in which the disconnection is confirmed is cut off from the back surface of the main body 1 with scissors, and the heat-generating wire 2 bonded to the main body 1 Alternatively, the meandering repair spare portion 10 of the heat-sensitive wire 3 is stretched to a straight line, and both the broken wire and the unbroken winding are cut according to the cut positions F and G as shown in FIG. Remove the tools 8a and 8b, and use new terminal fittings 8a and 8b to perform soldering 9a and 9b as shown in FIG. 7, and further cut any one of the cut positions A of the heat insulating material as shown in FIG. To E Te, had Unishi'll perform the repair paste the guard cloth 11.

[Problems to be solved by the device]

 However, when the spare part 10 for repairing when the soldered terminal portion of the heating wire 2 or the heat-sensitive wire 3 is disconnected is provided on the main body 1 side as described above, the spare part 10 for repairing is repaired. In order to stretch the wire straightly, the heat insulating material on the back surface side of the main body 1 must be cut and opened, which is troublesome. Further, since there are spare parts 10 for repair formed in a meandering shape in the vicinity of the controller 4 on the main body 1 side of the heating wire 2 and the heat-sensitive wire 3, the wiring time using the wiring machine is long accordingly. There was a drawback.

The present invention has been made in view of the above points, and when repairing a soldered terminal portion of a heating wire or a heat-sensitive wire, it can be easily performed without cutting the heat insulating material of the main body. It is an object of the present invention to provide a planar heating tool that can shorten the wiring time using a wiring machine for the main body of heating wires and heat-sensitive wires.

[0006]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention comprises a main body, a heating wire and a heat-sensitive wire wired to the main body, and a controller attached to the edge of the main body for controlling the temperature of the heating wire. In addition, a spare portion for repairing when the soldered terminal portion of the heating wire or the heat-sensitive wire is broken is provided on the controller side.

[0007]

[Action]

 According to the present invention, when the soldered terminal portion of the heating wire or the heat-sensitive wire is broken, the repair spare portion provided on the controller side is stretched to a straight line for repair.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. 1 and FIGS.

In FIG. 1, reference numeral 1 denotes a main body, and a heating wire 2 wired in two systems so that the area can be switched, and a feeling provided over the entire heating wires 2 of the two systems. A heating wire 3 is provided. Reference numeral 4 is a controller for controlling the temperature of the heating wire 2 and the like, and is attached to the edge of the main body 1. Reference numeral 5 is a terminal portion of the heating wire 2 and the heat-sensitive wire 3 that serve as a soldering terminal portion, which is located inside the controller 4, and is formed in a meandering shape near the terminal portion 5 and inside the controller 4 for repair. The spare parts 10 ... Are formed. As shown in FIG. 4, a core thread 2c is provided at the center of the heating wire 2, and a winding wire 2a wound around the core thread 2c, a heat-sensitive layer 2d, and a wound abnormality detection wire 2b are sequentially provided. As shown in FIG. 7, the terminal portion 5 has the heating wire 2a soldered to the terminal fitting 8a 9a and the abnormality detection wire 2b soldered to the terminal fitting 8b 9b. Further, as shown in FIG. 5, the heat sensitive wire 3 is provided with a core thread 3c at the center, and a primary temperature sensor 3a wound around the outer circumference of the core thread 3c, a heat sensitive layer 3d, and a wound secondary temperature sensor 3b. As shown in FIG. 7, the terminal portion 5 is sequentially provided with the primary temperature sensor 3a soldered to the terminal fitting 8a 9a, and the secondary temperature sensor 3b soldered to the terminal fitting 8b 9b. ing. The components shown in FIGS. 6 and 7 are commonly used for the sake of explanation.

However, when the sheet heating device thus formed is in use, an external force is applied to the soldered terminal portion of the heating wire 2 or the heat-sensitive wire 3 due to some impact, so that either the heating wire 2 or the heat-sensitive wire 3 is exposed. If any of the windings is broken, the spare portion 10 for repair provided in the controller 4 of the heating wire 2 or the heat-sensitive wire 3 in which the disconnection is confirmed is linearly stretched, and is shown in FIG. 6 as in the conventional case. Cut both the broken wire and the unbroken wire according to the cutting positions F and G, remove the terminal fittings 8a and 8b, and solder them using new terminal fittings 8a and 8b as shown in FIG. Repair is completed by performing 9a and 9b. Further, since the repairing spare portion 10 formed in a meandering shape is provided on the controller 4 side, the wiring time of the heating wire 2 and the heat-sensitive wire 3 to the main body 1 can be shortened.

[0011]

[Effect of device]

 According to the present invention, a spare part for repair is provided on the controller side when repairing a soldering terminal portion of a heating wire or a heat-sensitive wire, so that the heat insulating material of the main body is not cut out. This can be done easily on the controller side, and the time required to wire the heating wires and heat-sensitive wires to the main unit using the wiring machine can be shortened.
