are laminated, and the energized heating element 21 is connected to the heat storage material 20.
The heat storage material 20 is embedded in the heat storage material 20 so as to form the upper surface of the heat storage material 20 . The upper surface of the heat storage material 20 is a rack locking surface portion 17,
It is on the same level as 17.

Here, as the outer shell material forming the channel 15, metal, plastic, wood, etc. can be used as appropriate. Further, as the heat insulating material 19, a synthetic resin foam such as foamed polyurethane, foamed polyethylene, or foamed polystyrene is usually used, and is attached to the channel 15 with an adhesive.

As the heat storage material 20, gypsum mortar, lime mortar, cement mortar, or a heat storage material that utilizes latent heat is used. For example, gypsum mortar is poured in liquid form onto the heat insulation material 19, and while the energizing heating element 21 is buried. Let solidify. Any type of energizing heating element 21 can be used as long as it generates heat when energized, but in consideration of uniformity of heat generation, it is preferable to use a planar heating element as shown.

As is already known, a sheet heating element is
This is a flat heating element made of a synthetic resin mixed with conductive powder, with electrodes embedded at intervals, covered with an insulating synthetic resin sheet, and lead wires attached to the electrodes. .

FIG. 3 shows a second embodiment of the present invention, in which the upper surface of a heat storage material 20 is covered with aluminum vapor-deposited paper 22. As shown in FIG. This aluminum vapor-deposited paper 22 is used to make the temperature distribution uniform due to the heat generated by the energized heating element 21, to prevent moisture, and to protect the heat storage material 2 from which the carpet or the like is exposed when the carpet or the like is laid directly on the floor heating unit 10.
It has functions such as preventing dirt from being contaminated by zero.

FIG. 4 shows a third embodiment of the present invention, in which the heat storage material 2

7 and 17 are partially provided along the longitudinal direction of the channel 15.

Although the lamination of the heat storage material and the heat insulating material and the embedding of the energized heating element are not shown in the drawings, they can be carried out as in Examples 1 to 3 (FIGS. 1 to 4) described above.

FIG. 6 shows a fifth embodiment of the present invention, in which the joist 1
The floor heating unit 10 of the present invention is mounted between the joists 14 and 14 while being supported by the mounting brackets 30. The mounting bracket 30 is formed of a metal plate, and has a nail hole 3.

When installing the floor heating unit of the present invention, for example, as shown in FIG. , 14, and fixed the floor heating unit 10 to the joists 14 by driving nails into the nail holes 19. In the same way, the units were successively installed between the joists, and the lead wires of the energized heating element 21 were connected to the terminal box. Later, a carpet or the like may be laid directly on the floor heating unit 10, or the unit 10 may be
A floorboard 25 or tatami mat is laid on top as shown in FIG.

Although Fig. 1 shows the case where the joists 14 are passed directly over the main drawers 13, a floor board is laid on top of the main drawers 13, the joists are passed over this board, and the floor joists are placed between the joists. The heating unit can also be installed as described above.

〔Effect of the invention〕

The floor heating unit of the present invention as described above is
It consists of a channel formed of an outer shell material that has a U-shaped cross section and has a predetermined length and a width narrower than the spacing between the juxtaposed joists.The lower part of this channel is filled with insulation material, and the In addition to filling the heat storage material, an energized heating element was buried in the heat storage material to form the upper surface of the heat storage material. It can be handled as an independent member.

By making it a complete, independent member, there is no need to make any further modifications to the unit itself at the construction site other than wiring for energization.

In addition, the structure is simple because the insulation material is filled in the lower part of the channel, the heat storage material is filled on top of the insulation material, and the heating element is buried to form the upper surface of the heat storage material, so the spacing between the joists is determined. If it is done, it will not only be possible to mass-produce it and reduce the price, but also because it is a completed component, it can be stored and stored.
Easy to transport to the construction site.

Moreover, since the heat insulating material, energized heating element, and heat storage material are housed within the channel formed by the outer shell material, they are sufficiently protected against external shocks, and are protected against vibrations and shocks during storage, transportation, and construction. Damage can be prevented.

Furthermore, according to the present invention, the lower part of the channel is filled with a heat insulating material, and the energized heating element is buried on the heat storage material filled on top of the heat insulating material, so that the wasteful release of heat to the underfloor is prevented by the heat insulating material. You can avoid it as much as possible.

In addition, since the current-carrying heating element is buried in the heat storage material to form the upper surface of the heat insulating material, the position of the current-carrying heating element is close to the floorboard installed on the floor heating unit, which rapidly increases the temperature of the heated space. This is an effective measure against nighttime temperatures when the temperature drops significantly.

Furthermore, when the flooring is made of wood, which has poor thermal conductivity, heat can be transferred directly from the energized heating element to the flooring, thereby reducing the temperature rise of the flooring.

Furthermore, since the heat from the energized heating element is transferred to both the flooring material and the heat storage material, a high temperature energized heating element can also be used.

Furthermore, if channels are inserted between the joists and carpets, floorboards, or tatami mats are laid on top of the channels, the floor heating unit will not be exposed to the heating space, so the living space will not be constricted. Furthermore, since the energized heating element is embedded in the heat storage material, there is no risk of fire outbreak and a comfortable heated space is provided.
It is also extremely easy to remove when heating is no longer needed.
