As a result, floor-standing electric heating devices of various sizes can be constructed. By sharing such heating equipment units, inventory management can be facilitated and manufacturing costs can be reduced.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a floor-standing electric heating device, such as an electric carpet, which is composed of a plurality of heating device units 2, a wiring frame 3, and a controller 4.

The plurality of heating equipment units 2 are all rectangular in size and have the same structure. For example, in the case of this embodiment, it is square and the heater 5
and a heat-sensitive wire 6 are built in at least. In this embodiment, a heating wire is used for the heater 5,
This heater 5 and the heat sensitive wire 6 are connected to the unit 2.
The wiring is arranged in a meandering pattern over almost the entire area. Unit-side terminals 8 are connected to the ends of these heaters 5 and heat-sensitive wires 6, respectively.
is exposed on one side of the warming device unit 2. Although pins are used for the unit side terminals 8 in this embodiment, the unit side terminals 8 may be formed with pin receiving holes.

The wiring frame 3 forms a border around the plurality of heating device units 2 which are connected to each other. The frame 3 has a substantially U-shaped cross section as shown in FIG. 2, and is adapted to be fitted onto the side edge of the warming device unit 2. A conductive path 9 made of an electric wire or the like is provided on the inner surface of the wiring frame 3, and a plurality of power supply side terminals 10 are provided at intervals. Each power supply side terminal 10 is adapted to be removably fitted into the unit side terminal 8. A connector 11 to which one end of the conductive path 9 is connected is attached to a part of the outer surface of the wiring frame 3. In this embodiment, the wiring frame 3 is made of flexible resin, but it may also be constructed by connecting four rigid frame members at their ends. Here, the wiring frame has a substantially U-shape, but it has a rectangular tube shape with four sides closed, and the wiring is routed inside, with each power terminal 10 coming out on one side. There is no problem.

The controller 4 has a relay connector 12 and a power plug 13.
is adapted to be detachably connected to the connector 11. The controller 4 is configured to individually control the temperature of the heating unit 2, for example, and an example of a specific electric circuit thereof is shown in FIG.

In other words, since the control circuits for each heating device unit 2 are the same and parallel, one of them will be explained. That is, the heater 5 is connected to the AC power supply 14 via a current control element such as a thyristor 15, and the heat-sensitive wire 6 is attached to the heater 5 via a heat-sensitive layer 16 having negative resistance to heat. One end of the heat sensitive wire 6 is connected to the gate of the thyristor 15 via a pulse generating element such as a neon lamp 17, and the other end of the heat sensitive wire 6 is connected to the AC power source 14 and the thyristor 15 via a variable resistor 18. connected to the points. Note that 19 in FIG. 3 is an overall switch. According to this electric circuit, the firing state of the thyristor 15 is controlled by the resistance value change accompanying the temperature change of the heat-sensitive layer 16, and the energization to the heater 5 is controlled, so that the temperature of the heater 5 is kept within a predetermined range. can be retained.

When assembling the electric carpet having the above structure, the number of heating equipment units 2 to be used is selected. Depending on the number of heating equipment units 2 used at this time,
It can be adapted to various sizes such as one tatami mat, two tatami mats, three tatami mats, etc. After this, the wiring frame 3 prepared according to the above-mentioned size is used to frame the entire plurality of heating equipment units 2, and at this time, the power supply side terminal 10 and the unit side terminal 8 of each heating equipment unit 2 are connected. Mate and connect. This assembled state is shown in FIG.

In use after this assembly, the relay connector 12 of the controller 4 is connected to the connector 11 of the wiring frame 3, and the power socket 13 is connected to the connector 11 of the wiring frame 3.
into an outlet (not shown), set a predetermined temperature using the controller 4, and connect each heating device unit 2.
What is necessary is to make the heater 5 generate heat.

By using the carpet in this way, users who sit or sit on the carpet can gain warmth. Moreover, in this embodiment, the controller 4 controls each heating device unit 2.
Since the temperature can be controlled individually, it is only necessary to generate heat in the necessary heating unit 2, resulting in an energy saving effect.

In addition, when using it as a mere carpet without heating, remove the relay connector 12 of the controller 4 from the connector 11 of the wiring frame 3,
It is sufficient to store the controller 4 in an appropriate location and use only the plurality of heating device units 2 whose shape is maintained by the wiring frame 3.

In addition, if it is not going to be used, you can disassemble the entire unit by following the reversal of the above assembly procedure and store the heating unit 2 in an appropriate location. Because it is curved, it can be stored even in a small space. In this embodiment, since the wiring frame 3 has flexibility, the entire wiring frame 3 can be collapsed into a linear shape and stored as appropriate.

If the heater 5 or the heat-sensitive wire 6 breaks down or otherwise breaks down due to the above usage, it can be repaired by replacing only the malfunctioning heating device unit 2 with a new heating device unit 2, so the entire electric carpet can be repaired. There is no need to replace it, and the cost of repair is reduced.

Moreover, in manufacturing the electric carpet as described above, the size of the electric carpet can be set depending on the number of heating unit 2 used, and therefore, the heating unit 2 can be used in common for electric carpets of various sizes. Because it can be made into parts, this standardization makes manufacturing and inventory management easier, and it is possible to reduce costs.

Although the above embodiment is configured as described above, in the present invention, the controller may control each heating device unit to the same temperature at the same time, and may not be able to be separated from the wiring frame. Moreover, it may be directly fixed to the outer surface of the wiring frame. Furthermore, the present invention is applicable not only to electric carpets but also to so-called floor heaters used in kitchens and the like.
