[0002]

2. Description of the Related Art Conventionally, as a heating apparatus for a house or the like, a floor heating apparatus provided with a heater driven by electricity or gas below a floor material is known. On the other hand, as shown in FIG.
The heat storage type floor heating apparatus which is excellent in economics and can save the heat of the heater H provided below the floor material 7 in the heat storage material 5 and gradually reduce the operation time of the heater H by gradually releasing the heat storage. B is also known. In this case, the heater using the electrically driven heater H has an advantage that the heat storage material 5 is heated and stored by inexpensive midnight power of the electric charge, and the heat storage can be used in the daytime.

[0003] More specifically, this regenerative floor heating device B is constructed by interposing a joist 9 between a plywood C and a floor material 7 above a heat insulating material 4 provided between, for example, large-scale (not shown). A space A is provided, and a heater H and a heat storage material 5 are provided in the space A. Then, the heat of the heater H is stored in the heat storage material 5, and the heat released from the heat storage material 5 becomes radiant heat via the space A to heat the floor material 7.

The heat stored in the heat storage material 5 is:
For example, a person is absent in the room for 24 hours, or a constant heat is less likely to be released even in a living room where heating is unnecessary when going out or going to bed. It is not necessary to operate the heater H at regular intervals, and is excellent in terms of economy and energy saving.
As shown in FIG. 7, there is an application filed by the present applicant as Japanese Patent Application No. 10-239315.

More specifically, the regenerative floor heating device D is capable of freely controlling the amount of heat released from the heat storage material 5, and is provided above the heat insulating material 4 provided between the large-scale (not shown). A space portion A is provided between the plywood C and the floor material 7 with joists 9 and 9 interposed therebetween, and a heater H and a heat storage material 5 are provided in the space portion A. As a heat radiation amount control device, an inflatable and deflateable bag body 6 is provided on the upper surface of an upper surface of a surface body 61 having a low thermal emissivity (high heat conductivity) such as an aluminum foil or a copper foil.

[0006] A fan (not shown) connected to the duct is provided in the bag body 6 as blowing means for blowing air into the bag body.
The amount of heat transfer from the heat storage material 5 to the floor material 7 is controlled by controlling the amount of air blown by the fan. That is, the heat released from the heat storage material 5 due to the heating of the heater H stored in the heat storage material 5 is promoted by expanding the bag body 6, and the surface body 61 is formed by deflating the bag body 6.
From above, the heating of the floor material 7 as radiant heat via the space portion A is suppressed, and the amount of heat transfer from the heat storage material 5 to the floor material 7 is controlled.

Therefore, there is an effect that the running cost for storing heat in the heat storage material 5 can be reduced. In addition, the outside air temperature is high and heating is not required, for example, in early spring or autumn, and also during the daytime when the temperature becomes high within the day, the heat release from the heat storage material 5 is controlled to raise the room temperature more than necessary. It also has the effect of not letting it do.

, The heating means is a heater panel 2 in which an electric heater 22 is integrated in a substantially plate shape on a wooden board, and an adjacent large pulling 8 is provided below the heater panel 2. A substantially plate-shaped heat insulating material 4 is provided which fits substantially between the eight, and the heater panel 2 is installed so as to support the heat storage material 5.

Further, in the regenerative floor heating apparatus of the embodiment, the heater panel 2 is formed to have a long shape so that the width thereof substantially matches the module between the joists 9 and 9, and the plurality of heater panels 2 are formed. It is also erected between the main lines 8,8.

More specifically, the regenerative floor heating device 1 is configured to store heat in a space A between a heater panel 2 provided with a heat insulating material 4 thereunder and a wooden floor material 7 as a floor component 7. Lumber 5
And a bag 6 for controlling the amount of heat radiation between the heat storage material 5 and the floor material 7.

The heater panel 2 heats the heat storage material 5, and as shown in FIG. 2, an overheating prevention sensor in which a wooden board surface material 21, an electric heater 22, a thermostat and a temperature fuse are integrated. 23, a urethane foam material for heat insulation is cast and fixed below the aluminum sheet 24 inside the frame member formed of wood in the lower layer of the surface material 21. In this case, the heater panel 2 is, for example, 250 mm in width, which substantially matches the module between the joists 9 and 9 where the heater panel is installed,
It is a long piece having a length of about 1900 mm, which can be installed between the two large drawers 8, 8, and has a connection portion 25 for connecting adjacent heater panels 2 at one end in the longitudinal direction. You.

The electric heater 22 is formed of, for example, a cord-like nichrome wire heater, and is disposed, for example, spirally in a plan view on one surface below the surface material 21 so as to be substantially plate-shaped.

The heat insulating materials 4 and 4 are made of, for example, urethane foam. In this case, as shown in FIG. It has a length of approximately 900 mm so as to match. In this case, the heater panel 2 is provided with a clearance interval slightly larger than the width dimension of the large-scale pull 8, and in this case, the two heat insulating materials 4, 4
Are bonded and integrated.

The heat storage material 5 is heated by the heater panel 2 and stores heat. For example, a latent heat storage material mainly composed of paraffin is sealed in an aluminum sheet, and in this case, a predetermined thickness and a joist are used. In the width of the module between 9 and 9,
For example, it is formed in a long plate shape having a predetermined length such as 800 mm.

The bag 6 controls the amount of heat radiation from the heat storage material 5 to the floor material 7 and has a fan (not shown) connected to a duct as blowing means for blowing air into the inside thereof. By controlling the amount of air blown by the fan, the heat radiation from the heat storage material 5 to the floor material 7 is controlled. That is, the bag body 6 is formed of, for example, various resins, plastic sheets or films, etc., which are expandable and contractible and have a high thermal emissivity, that is, a low thermal conductivity. Is affixed. The bag body 6 has, for example, a width dimension of approximately 250 mm substantially corresponding to the module between the joists 9 and 9 and a length dimension of approximately 2700.
The duct is provided between the joists 9 and 9 at one end in the longitudinal direction. Bag 6
The air is blown from the fan to send air into the bag 6, and the air can be exhausted.

The flooring 7 is, for example, a plywood having a predetermined thickness, and is formed in a long flat plate shape having a predetermined external dimension. The floor material 7 has a decorative surface on the surface side of which a color urethane coating treatment is applied, and when a plurality of surface materials of the floor heating device are connected and arranged on the decorative surface, the mutual A V-cut groove is provided on the decorative surface so that the joint is not conspicuous.

In the above-described regenerative floor heating device 1, first, as shown in FIG. 3, joists 9 are erected on the upper surface of the girders 8 at module intervals. An electric heater 22 is substantially attached to a surface member 21 having a substantially plate-shaped heat insulating material 4 and 4 fitted below the surface material 21 having a long shape so that the width thereof substantially matches the module between the joists 9 and 9. In this case, the heater panel 2 integrated in a plate shape is dropped between joists 9 so as to be bridged between the three large drawers 8, 8, 8. Then, as shown in FIG. 1, the heat storage material 5 and the bag 6 are sequentially dropped into the space A between the joists 9, 9 erected on the large pulling 8, and are supported by the heater panel 2 and placed. Thereafter, the floor material 7 is fixedly installed on the upper surface of the joist 9.

In the regenerative floor heating device 1, when the fan is operated, air is blown into the bag 6 through a ventilation duct provided in the bag 6, and the air is blown into the bag 6.
The internal pressure rises and the bag body 6 expands, and the upper side of the bag body 6 comes into close contact with the back surface of the floor material 7 to be in a heat dissipation promoting state. In this state, the air layer formed inside the bag body 6 is formed of a material having a high emissivity on both the upper surface and the lower surface of the air layer. The thermal resistance is reduced, and the release of heat from the heat storage material 5 due to the heating of the heater panel 2 stored in the heat storage material 5 is promoted by expanding the bag 6.

When the operation of the fan is stopped, the bag 6 collapses due to its own weight. In this state, the air layer of the space A formed between the back surface of the flooring 7 and the face body of the upper surface of the bag body 6 has the lower face formed of a face material having a low emissivity. This is a heat dissipation suppression state in which the thermal resistance of the air layer is greater than in the heat dissipation promotion state. In this state, the heating of the floor material 7 due to the radiant heat from the face body via the space portion A is suppressed. In this way,
The amount of heat transfer from the heat storage material 5 to the flooring material 7 can be controlled because the thermal resistance of the closed air layer is inversely related to the thermal conductivity of the material itself. When the copper material is used as the surface member constituting the air layer of the space A, the thermal resistance of the air layer is increased and the heat radiation is suppressed.

Therefore, according to the regenerative floor heating apparatus 1 described above, the space surrounded by the joist 9 laid on the large-scale pulley 8 and the flat floor component 7 provided on the joist 9.

In addition, since it is supported and installed, there is no need to provide a special member for installing the heat insulating material 4 under the floor, so that there is no erroneous construction even by an unskilled worker.

A heater panel 2 having an elongated shape so that the width thereof substantially matches the module between the joists 9 and 9 is laid between a plurality of large drawers 8 and 8 to form a heat storage material 5.
Can be easily installed without using a fixing tool such as a nail, so that the installation time can be shortened.
