[Detailed Description of the Invention] [Industrial Application Field] The present invention can be used as a heating floor by laying a plurality of sheets and laying carpets, floor carpets, etc. This invention relates to a floor heating device for heating floorboards by installing it in a room.

[Conventional technology]

Conventionally, various floor heating devices have been known that are attached to the back side of a floorboard in a room to heat the floor and the room. Underfloor heating devices have been proposed that include a heat storage material on the entire surface of the floorboard, an energized heating element below it, and a heat insulating material below it.

[Problem to be solved by the invention]

However, these conventional floor heating devices require large-scale floor construction during building construction, and it is almost impossible to change the heating conditions once installed.

In addition, in the case of underfloor heating in rooms that require complex and large amounts of wires to be wired under the floor, such as modern intelligent buildings and computer rooms, conventional large-scale floor heating requires a significant amount of wires to be wired. It was difficult.

The present invention eliminates the drawbacks of such conventional floor heating equipment,
It is an object of the present invention to provide a floor heating device that allows easy wiring of electric wires and the like under the floor of a desired location.

The floor heating device of the present invention for achieving the above object is a flat, thin box-like object consisting of a lid and a box, and an energizing heating element is disposed on the box side of the lid, The present invention is characterized in that a convex portion protruding toward the lid is provided on the bottom surface of the box, and the tip of the convex portion is fixed to the lid.

Hereinafter, embodiments of the floor heating device of the present invention will be described based on the drawings.

FIG. 1 shows an outline of a floor heating device 1 of the present invention,
The floor heating device 1 of the present invention consists of a lid 2 and a box 3, and as a whole is a flat, thin box-like object as shown in FIG.

Although the size of the lid body 2 can be arbitrarily selected, it is preferable that the lid body 2 has a square shape of 50 x 50 cm as shown in FIG. On the back side of the body, that is, on the side of the box body 3, an energized heating element 4 led from the power source is arranged, and in order to keep the temperature of the lid body 2 constant and improve safety, a thermostat and a temperature fuse are installed. An overtemperature rise preventer 5 built into the case is appropriately provided.

As the energizing heating element 4, a synthetic resin-coated heating wire, a metal etching heating element, a heating element using metal powder, a carbon-based heating element, etc. are used.

When attaching such a current-carrying heating element to the back side of the lid, the back side of the lid is coated with an adhesive that can be thermally bonded to the current-carrying heating element, and the current-carrying heating element is heated through this adhesive. It may be fixed by fusion, or a current-carrying heating element may be attached in advance to the non-adhesive side of a metal foil such as a thin metal plate or aluminum foil coated with adhesive on one side, and the adhesive side may be attached to the lid. There is a method of gluing it to the back side, or attaching a thin metal plate or metal foil coated with adhesive on both sides to the back side of the lid with adhesive on one side, and attaching i! to the adhesive side on the other side. A method such as bonding an electric heating element is adopted.

When using a thin metal plate or metal foil in this way, you can use a thin metal plate or metal foil with the same size as the back of the lid, or you can use a thin metal plate or metal foil with adhesive applied on both sides. It is also possible to adhere a foil to the planned attachment position of the current-carrying heating wire, and then bonding the current-carrying heat-generating element to this strip-shaped thin metal plate or metal foil.

As described later, in consideration of the case where the lid and the box are fixed by welding, the thin metal plate, metal foil, and adhesive layer at the welding position are placed so that the lid 2 and the box 3 are in direct contact with each other. It is preferable to make, for example, a circular hole in the hole.

Since the floor heating device has a thin box shape as described above, the floor heating device of the present invention can be installed in a narrow space under the floor, and is advantageous in increasing the strength of the floor heating device.

As shown in FIGS. 4 and 5, the bottom surface 8 of the box body 3 is formed with a convex portion, for example, a hemispherical convex portion 9, which protrudes toward the lid body 2. The tip of the convex portion 9 The portion 9A is fixed to the lid body 2.

This convex portion 9 has the function of fixing the box body 3 to the lid body 2 and increasing the strength of the floor heating device.

The shape of the convex part 9 is not particularly limited and can be determined as appropriate, but in view of the ease of manufacturing the box body 3 and the ease of welding between the convex part and the lid body, the shape shown in FIG. 4 is usually used. A hemispherical shape as shown is preferred.

A semi-cylindrical convex portion 10 connecting adjacent hemispherical convex portions 9.9
Similarly, the box body 3 has a function of increasing the strength of the box body 3.

The convex portion formed on the bottom surface 8 of the box body 3 can be fixed to the lid body 2 by welding, using an adhesive, or by forming a hole in the lid body corresponding to the tip of the convex portion and using a bolt or donut. A method of fixing using tapping screws or the like is adopted.

Further, the support portion 7 is fixed to the lid body 2 at the position indicated by the cross by welding, a bolt donut, a tufting screw, or the like.

As for the material of the box body 3, in addition to metal, wood, synthetic resin, ceramic material, etc. are used.

Next, the above-mentioned lid body 2 (Fig. 3) is equipped with an energized heating element.
When stacked on the box body 3 (FIG. 4), the floor heating device of the present invention is formed, and the positional relationship between the energizing heating element 4 and the convex portion 9 is as shown in FIG. 6. That is, the energizing heating element 4 should avoid the tip 9A of the protrusion 9 of the box 3 and be arranged in the space between the lid 2 and the box 3, especially in the space other than the tip of the protrusion 9. is clear.

Next, a method for constructing the floor heating device of the present invention will be described based on FIGS. 7 and 8.
