Description

[Detailed description of the invention] Panel heaters currently on the market have a fixed shape, so they cannot be adjusted in the length direction, there are restrictions on where they can be installed, and they require a large storage space even when not in use. It had drawbacks. In order to eliminate this drawback, it has been proposed that two planar heater bodies are arranged side by side across a space so that they can be moved left and right, thereby making it possible to adjust the length.

However, in this case, the heat dissipation from the part of the rear sheet heater body that overlaps with the front sheet heater body is not effectively utilized, and electricity is wasted. was.

The present invention has been made for the purpose of solving the above-mentioned drawbacks and providing a planar heater whose length and heat generating area can be adjusted according to the installation location or heating object.

Next, one embodiment of the present invention will be described based on the drawings. Reference numeral 1 indicates a front planar heating device with a planar heating element 11 embedded inside, and reference numeral 2 indicates a rear planar heating device with three planar heating elements 21 connected in parallel in the length direction embedded inside. This is the main body of the aircraft. Electrodes 12 are provided at the upper and lower ends of the planar heating element 11, and a set of screw holes 13 communicating with the terminals of the electrodes 12 are provided at the top and bottom near the left end of the back surface of the planar heater main body 1. ing.

On the other hand, individual independent electrodes 23 are provided at the upper ends of the three planar heating elements 21, and a switch 24 is connected between two adjacent electrodes to form a normally closed circuit. Two planar heating elements 21 are provided, and one long electrode 22 common to the three heating elements is provided at the lower end of the planar heating element 21.

Near the right end of the front surface of the main body 2 of the sheet heating device, there are a set of screw holes connected to the terminals of the electrodes 23 and 22 on the upper and lower sides, and near the left end there are a set of screw holes 27 unrelated to the electrodes, respectively. At the same time, a screw hole 25 is provided between the two, and the upper part is a screw hole 25 through which the switch 24 passes.
Two sets of screw holes 26 communicating with the terminals of the electrodes 22 are provided at the bottom.

When using, two sheet heater bodies 1 and 2 are required.
is provided with male screw parts at both ends of the electrically good conductor 31,
The connecting bolt 3 whose intermediate part is covered with an insulator 32 is
The main body 1 is connected by screwing into one of the screw holes 13 on the back side of the sheet heater body 1 and four sets of screw holes on the front side of the sheet heater body 2.

When the connecting bolts 3 are screwed into a set of screw holes near the right end of the planar heater body 2, all three planar heating elements 21 are energized, but the middle switch 24 is energized. When screwed into the threaded hole 25 that communicates with the set of upper and lower threaded holes, the switch is opened by the tip of the connecting bolt 3 as shown in FIG. is not energized, and only the sheet heating element 21 on the left side is energized. Also, when screwed into the set of screw holes 27 near the left end,
All three planar heating elements 21 are not energized.

In this invention, the configuration is as described above, so when the width is adjusted and the two heater bodies overlap, the part of the rear heater body that is shaded by the front heater body will generate heat. Therefore, it is possible to prevent unnecessary power consumption and also to prevent overheating.
