Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a regenerative heating flooring, and more particularly to a regenerative heating flooring having a small thickness and a natural walking feeling.

[0002]

2. Description of the Related Art In recent years, demand for an electrically heated floor heater has been increasing because of its high safety as a heating device and its cleanliness that does not pollute indoor air. Above all, regenerative floor heating is expected to be an economically advantageous heating device because it can secure a heat source using inexpensive midnight power.

[0003] This type of floor heating is constructed by incorporating a heat storage material which is solid at room temperature, changes into a liquid phase when heated, and stores heat, and is released when the phase changes from a liquid to a solid. The floor is heated by heat,
Heating is performed using heat storage in the heat storage material based on midnight power and heat release during the day.

[0004] The heat storage material is constituted by a polypropylene container or the like containing a heat storage material such as sodium sulfate or sodium acetate. The heat storage material and the heater panel are provided on a joist of a building, and a floor finishing material is provided thereon. This forms a predetermined floor heating structure.

[0005]

However, according to the conventional regenerative heating floor material, in order to cope with the load and impact applied to the floor, the polypropylene container must be made thick, sturdy, and therefore thick. In addition, the heater panel is combined with this, and the thickness of the flooring as a whole becomes large, and as a result, there is a step between the floor and the floor that is not heated. Often difficult.

In addition, setting the dimensions of the polypropylene container in consideration of such a step on the floor affects the amount of the heat storage material to be stored, and causes a state in which sufficient heat storage properties cannot be secured. To address this problem, it is conceivable to reduce the thickness of the polypropylene container. However, thinning the container means a decrease in strength, and the floor surface may sink during walking, impairing walking sensation.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a heat storage type heating floor material which can be made thinner as a whole, and which is excellent in strength so that the floor surface does not sink during walking. .

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a receiving portion surrounded by protruding edges,
A floor material main body having a protrusion formed in the housing portion, a plate-shaped heat storage material housed in the housing portion, a heater unit stacked on the heat storage material and housed in the housing portion; A heat storage material and a heater unit, which are bound by covering the heat storage material and the heater unit in the housing portion, and are provided with a lid material supported by the edges and the protrusions, to provide a heat storage type heating floor material. It is.

The floor material main body is formed by integrally molding plastics or a metal material, or a combination thereof by using an adhesive, and the lid member is also formed by a molded plastics material or a metal material.

It is preferable that the housing portion of the floor material main body is divided into a plurality of areas by the projections. Therefore, the heat storage material to be housed here is also divided into a plurality of areas, and the heat storage material is housed in each of the plurality of sections. preferable. As compared with the case where one heat storage material is used, the influence when an abnormality such as damage occurs in the heat storage material can be minimized.

Since the heat storage material is housed in the housing part of the floor material main body, it does not need to have the strength itself as a floor constituent material as in the case of using a conventional polypropylene container. Therefore, as a result, for example, by adopting a configuration in which the heat storage material is covered with the resin film, the occupancy of the heat storage material can be set to the maximum, and the thickness can be set to the minimum.

As the heater unit, a heater wire in a meandering shape, a planar heating element in which carbon or the like is mixed in rubber or plastics, or the like is used. It is preferable to arrange a metal sheet such as an aluminum sheet on both sides of the heater unit, thereby uniformly distributing heat over the entire surface of the metal sheet.

It is practical to incorporate a temperature controller such as a thermostat at an appropriate position of the heater unit to automatically adjust heat generation. When there is no heat storage in the heat storage material, floor heating based on the heater unit is performed.

[0014]

Next, an embodiment of a regenerative heating floor material according to the present invention will be described. In FIG. 1A, reference numeral 1 denotes a floor material main body having a housing portion 3 surrounded by a protruding edge portion 2 and having three projections 4 in a central longitudinal direction of the housing portion 3. The edge 2 does not necessarily have to be continuous around the housing 3. It may be cut off in the middle as shown in the figure, or may be formed as dots at appropriate intervals.

FIG. 2 shows a heat storage material housed in the housing part 3. The heat storage material 5 is a solid and plate-like heat storage material at room temperature, which is covered from above and below by a polyethylene terephthalate film 6, and the joint of the film 6 is sealed. It is constituted by. FIG. 2B shows the structure of the heat storage material 7, in which the air inside the film 6 is removed and the film 6 is airtight so that the liquefied heat storage material does not leak.

As shown in FIG. 1A, six heat storage materials 7 are assembled and accommodated on both sides of each projection 4 respectively. Reference numeral 8 denotes a heater unit. FIG. 3 shows a configuration of the heater unit 8, in which the heater wire 9 is arranged in a meandering shape.
It is constituted by laminating a thin aluminum sheet 13 for evenly distributing heat from both sides of a sheet-like material 12 composed of a power supply line 10 for supplying electric power and a thermostat 11 arranged at the center. .

In the heater unit 8 shown in FIG. 1A, the heater wires 9 and the like are shown protruding from the thin aluminum sheet 13, and therefore, the heater unit 8 is much different from a conventional heater panel. It is composed thinly.

In FIG. 1A, reference numeral 14 denotes a cover material that covers the housing 2 to confine the heat storage material 7 and the heater unit 8 in the housing 2. When the lid member 14 is attached to the floor material main body 1, the lid member 14 is supported by the edge portion 2 and the projection 4 in the housing portion 3. FIG. 1B shows the regenerative heating floor material assembled as described above. In the drawing, reference numeral 15 denotes an electric wire or the like for supplying power to the heater unit 8.

In the heat storage type heating floor material according to the present embodiment configured as described above, even if the amount of the heat storage material 5 for sufficient heat storage is taken into consideration, the total thickness of the floor material is reduced to 15%.
mm, and therefore, with such a level difference, the height adjustment with the non-heating floor can be easily performed within the range of the architectural adjustment allowance.

[0020]

As described above, according to the heat storage type heating floor material according to the present invention, the heat storage material and the heater unit are housed in the housing part of the floor material body, and the housing part is covered by the lid material. The heater unit and the heater unit are housed in the floor material main body, which eliminates the need for the heat storage material and the heater unit to have independent strengths as floor constituent materials as in the past, and accordingly, the overall thickness is reduced accordingly. It can be made thin.
As a result, the step with the non-heated floor is reduced, and the height of the floor can be easily adjusted.

Further, since the lid member is supported not only by the edge protruding around the accommodating portion but also by the projection formed in the accommodating portion, the lid member can sufficiently withstand the load and impact acting thereon. Therefore, when walking on the floor, the floor does not sink and an unnatural walking feeling does not occur, and a floor excellent in strength can be formed.
