Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor heating unit, and more particularly to a floor heating unit that is extremely easy to install and can be installed by simply inserting it between the joists.

[Conventional technology]

Traditionally, for example, to heat a room, you would fold the
Alternatively, carpets were laid on the floor, or electric or kerosene stoves were used. However, simply laying carpet cannot compensate for the temperature drop in the heated space, especially the sudden temperature drop at night, and electric and kerosene stoves cannot prevent fires and air pollution problems. It was impossible.

[Problem to be solved by the invention]

The problem to be solved by the present invention is that conventional heating equipment cannot cope with a sudden temperature drop in a heated space, especially at night, without causing problems of fire or air pollution. It is a point.

[Means to solve the problem]

That is, the floor heating unit of the present invention consists of a channel formed of a shell material and having a U-shaped cross section, and the channel has a predetermined length and a width narrower than the interval between the joists arranged in parallel. A mounting locking surface for the upper surface of the joist is provided at the upper end of both side walls of the channel, a heat insulating material is filled in the lower part of the channel, and a heat storage material is placed on the second energized heating element placed on the heat insulating material. In addition to filling the heat storage material, a first energized heating element is embedded in the heat storage material so as to form an upper surface of the heat storage material.

The present invention will be described below based on embodiments shown in the drawings.

Joists 14 are provided on the joists 13 at regular intervals, and the floor heating unit 10 of the present invention is installed between the joists 14, 14 arranged in parallel. As shown in FIG. 2, the floor heating unit 10 consists of a channel 15 made of shell material and having a U-shaped cross section. In addition, at the upper ends of both side walls 16, 16 of this channel, mounting locking surfaces 17, 17 for engaging the upper surfaces of the joists 14, 14 are provided over the entire length of the channel 15. The length of the channel 15 can be arbitrarily determined, and its width can also be appropriately selected within a range smaller than the interval between adjacent joists 14, 14. Further, nail holes 18 may be provided in the rack locking surfaces 17, 17.

Although any type of heating element that generates heat when energized can be used, in consideration of uniformity of heat generation, it is preferable to use a planar heating element as shown in the figure.

As is already known, a sheet heating element is

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〕

As described above, the floor heating unit of the present invention consists of a channel formed of an outer shell material having a U-shaped cross section, a predetermined length, and a width narrower than the interval between the joists installed in parallel. A heat insulating material is filled in the lower part of the heat insulating material, and a heat storage material is filled on the second energized heat generating element placed on the heat insulating material, and a first energized heat generating element is placed in this heat storage material so as to form the upper surface of this heat storage material. Since the body is buried, it can be handled as an independent member for floor heating, which combines a heat insulating material, a heat storage material, and an energized heating element.

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, as 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 on top of the insulation material and the heat storage material, respectively, and the spacing between the joists is determined accordingly. 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 heat storage material is filled on top of the second energized heating element, and the first energized heating element is embedded in the heat storage material so as to form the upper surface of the heat storage material. If daytime electricity is used to energize the second energized heating element and cheap late-night electricity is used to energize and heat the first energized heating element, during the daytime when the temperature is less low, the second energized heating element is heated. The heated space can be sufficiently heated by the heat radiated from the heat storage material, and at night when the temperature drops significantly, in addition to the heat radiated from the heat storage material, the heat is released from the floorboards laid on the floor heating unit. the first located in close proximity
Since the temperature of the heated space can be rapidly raised by the energized heating element, it is possible to sufficiently cope with an increase in heat load due to a sudden temperature drop in the heated space at night.

Also, after inserting channels between the joists,
If you lay carpet, floorboards, or tatami mats on top of this, the floor heating unit will not be exposed to the heating space, so the living space will not be constricted, and since it uses an energized heating element, it will not pollute the air in the living space. Not at all. 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.
