Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a floor heating system installed between floor joists under a floor material of a house.

[0002]

2. Description of the Related Art It is well known that a conventional floor heating system is an extremely comfortable and best heating system when it is warmed up, but recently, a floor is called a floor for reasons of environmental hygiene in the interior of a house. Often finished with wooden floor heating.

Since it is made of wood and its thermal conductivity is not necessarily good, the surface of the flooring does not warm up easily even when the heating device for floor heating provided thereunder is heated. In particular, the floor heating system between floor joists, which consists of a large number of joists that constitute the underfloor and supports the floor material, and a heating device is installed between the floor joists, is the uniform thermal coupling between the heating device and the floor material as designed. Otherwise, the temperature rise may be poor and the temperature distribution on the entire floor may be uneven, resulting in a poor floor heating system.

For this reason, the heat generating panel, that is, the entire heating device is pressed against the floor material from below by the force of the elastic material, as shown in Japanese Utility Model Laid-Open No. 55-83612, so that heat transfer is good. You can see some ideas.

Further, as disclosed in Japanese Patent Laid-Open No. 4-194518, as a means for vertically moving the heat generating panel provided under the floor plate, that is, the entire heating device, the heat generating panel is mainly used for adjusting heat transfer. It is known that the thickness of an air bag provided at the lower part of the air bag is adjusted by air pressure or the like.

As described above, all of the above-mentioned conventional examples are intended to achieve the intended purpose by applying force from below to the entire heating device provided at the bottom of the floor plate for heat transfer and heat transfer. is there.

When the entire heating device is to be supported from below, the weight of the heating device including the outer shell material and the built-in components is added. Therefore, the force must be greater than the weight of the entire heating device. In particular, in the case of a heat storage type floor heating device, when a heavy object is used, the weight becomes heavy, so naturally large elastic force and pressure are required.

[0008]

As described above, in the conventional floor heating system, since the entire heating system is supported from below, the scale of the entire system for obtaining the effect becomes large, and as a result, the cost becomes high, and hence the floor system. There is a problem that it is difficult to introduce it in terms of price despite good heating.

As described above, there has been no means for contacting the lower surface of the floor material and the heating device easily and in a uniform state at low construction cost.

In view of the above, the object of the present invention is to introduce a new system into the internal structure of the heating device for the structure for effectively performing heat transfer and heat transfer in the floor material direction in the floor heating device. As a result, the same effect as described above can be obtained without supporting the entire heating device from below, the configuration scale of the entire heating device is small and simplified, and by facilitating the construction, the entire construction including the construction cost is reduced. It is to measure the spread of floor heating systems that reduce costs.

It is a heat case body, and is generally made of a rust-proof metal plate, and functions as a heat equalizing plate that makes the temperature distribution uniform depending on the specifications of the heating element 10 such as a heating element and protection from external force. .

Further, 9 is a lower flat plate-shaped heat shield case body in which an absorber 11 made of the same material as the heat spreader case body 8 is installed, and 9a is at an end of the heat shield case body 9. A separating portion 8a, which serves as a stopper, is provided at the end of the soaking case body 8 as a separating portion 8a which serves as a pair with the portion of the heat shield case body 9 facing the separating portion 9a.

The two separating portions 8a and 9a are for fixing the heat equalizing case body 8 and the heat shielding case body 9 so as not to separate them in a non-pressurized state as shown in FIG. 3 in which the heating device 7 is not installed.

Reference numeral 10 is a heating element such as a heater unit which is provided in close contact with the soaking case body 8 and has a heating element element whose surface including the surroundings is electrically insulated, and is preferably a closed temperature characteristic of the floor surface. A heating element (PTC heater) having excellent positive resistance temperature characteristics is suitable.

That is, when the heating element 10 such as a heater unit is laid on the lower portion of the floor material 6 in a large area of a room where humans live, the surface of the floor material 6 is often covered with rugs and furniture. Will be blocked.

Therefore, heat radiation from the floor surface is hindered at that portion, and since the electric input is the same in a normal heating element, the temperature rises by the amount of the heat radiation hindered.

However, in the case of the PTC heater, when the ambient temperature rises under various conditions and the temperature of the PTC heater itself also rises, the resistance temperature characteristic changes positively and the resistance value increases, Therefore, since the electric input is suppressed and the heat generation amount is suppressed, the temperature rise can be suppressed.

Further, considering that the heat generating element 10 such as a heater unit has a function of absorbing vibration and sound from the floor material 6, a soundproof effect to the floor can be expected when it is installed in an apartment house or the like. It is decided by.

Reference numeral 11 denotes an absorber having the functions of positioning, heat insulating and soundproofing of the expandable body 12 provided in the heat shield case body 9 of the heating device 7, and the central portion of the heat soaking case body 8 from above. When pushed, the soaking case body 8 and the heat generating body 10 such as the heater unit are of course minimized and protected.

Reference numeral 12 denotes an elastic body, which is provided between the heat equalizing case body 8 and the heat shield case body 9 in a required number in a well-balanced manner, and is preferably a versatile and inexpensive elastic body such as a coil spring. . Due to the function of the expandable body 12, the heat equalizing case body 8 and the heat shield case body 9 become a case body that expands and contracts in the vertical thickness direction, and the case body heating device 7 that expands and contracts under the floor in the structure as shown in FIGS. Is installed in the storage unit designed within the expansion / contraction dimension, the entire surface of the soaking case body 8 of the heating device 7 and the lower surface of the floor material 6 are brought into contact with each other in a good state.

An elastic body 12 such as an elastic body of a coil spring is housed together with the absorber 11 in the case body, and the positional stability of the elastic body 12 such as an elastic body is maintained and the expansion and contraction operation is stabilized.

Further, in order to improve the thermal contact between the heating element 10 such as a heater unit and the soaking case body 8, the elastic body 12 such as an elastic member is supported from below the heating element 10 such as a heater unit. It is an effective structure.

Depending on the method of supporting the elastic body 12 such as the elastic body 12 from the bottom of the heating unit 10 such as the heater unit, an adhesive or the like may not be used on the entire surface as a means for forming a close contact with the soaking case body 8 of the upper case. In both cases, a low-cost configuration that sufficiently obtains thermal coupling is possible.

Reference numeral 13 denotes a space inside the case between the heat generating body 10 such as a heater unit and the absorber 11, which has a heat insulating function and is provided so as to allow the case body to expand and contract in the vertical direction. .

In FIGS. 1 and 2, the heating device 7 is installed under pressure between the floor material 6 and the heat insulating material 5 between the joists 4, so that the thickness of the heating device 7 is compressed. It is thin.

Therefore, the elastic bodies 12 such as a plurality of elastic bodies, which are built in between the heat equalizing case body 8 of the upper case and the heat shield case body 9 of the lower case, are in a compressed state, and the space 13 in the case is also compressed. It is in the state of being The compressed state after installation is the separating portion 8 which functions as upper and lower stoppers.
Since a and 9a do not come into contact with each other at their respective surface portions, there is an effect that heat transfer from the soaking case body 8 of the upper case to the heat shielding case body 9 of the lower case is reduced and the downward heat leakage is reduced. It is a thing.

On the other hand, in the heating device 7 in the free state before construction shown in FIG. 3, the thickness of the heating device 7 is increased by elasticity of the plurality of built-in elastic bodies 12 because it is not pressed from the vertical direction. The upper and lower heat equalizing case bodies 8 of the upper case and the heat insulating case body 9 of the lower case are provided at the end portions of the upper case and the separating portion 8a serving as a stopper of the heat equalizing case body 8 and the lower case. The separating portion 9a, which functions as a stopper of the heat shield case body 9, swells to a state in which the separating portion 9a is in contact with the heat shield case body 9 to increase the thickness.

Therefore, the space 13 in the case body is also large.

Reference numeral 16 denotes a heat dispersion member, which is arranged above the heat equalizing case body 8 of the upper case and below the floor material 6, and has, for example, a mesh shape or a surface shape forming a large number of convex portions. It is composed of forming members.

Reference numeral 17 denotes a holding portion, which is provided along the heat generating body 10 so as to hold the heat generating body 10 provided inside the soaking case body 8 of the upper case.

Next, the construction method and procedure of the floor heating apparatus of the present invention will be described.

That is, in FIG. 1 and FIG. 2, joists 4 are arranged at regular intervals on the scraping material 3 lined with the thermal insulation material 2 between the large pulls 1 on the large pull 1.

The heat insulating material 5 between the joists 4 is provided between the adjacent joists 4 on the scraping material 3, and a required number of heating devices 7 are arranged on the heat insulating material 5 between the joists 4 to electrically connect them (not shown). ), The floor material 6 is fixed to the joist 4 to complete the work.

Here, when the heating device 7 is inserted between the adjacent joists 4, the dimension between the heat insulating material 5 between the joists 4 and the floor material 6 is
The surface of the soaking case body 8 of the upper case of the heating device 7 is the floor material 6
The thickness is set to be slightly smaller than the thickness (maximum thickness) of the heating device 7 in the non-pressurized state as shown in FIG.

Since the width of the allowable installation dimension is large as described above, even if the dimensions of the joists 4 and the dimensions of the heat insulating material 5 between the joists 4 vary to some extent, the surface of the soaking case body 8 of the upper case of the heating device 7 and the floor. The back surface of the material 6 can be contacted uniformly over the entire surface.

Further, although not limited to the floor heating device of the present invention,
In order to efficiently heat the room in which the floor heating is installed, in the configuration of the heating device 7 and each member around the heating device 7, basically, the heat flow from the heat source such as the heating element 10 such as the heater unit is not limited to the room to be heated. It is important to keep it from flowing.

In other words, it is necessary to reduce the thermal resistance in the room direction as viewed from the heat source and increase the thermal resistance in the opposite direction to the room.

As shown in FIG. 4, a heating device 7 is provided under the flooring 6 between the joists 4 with a heat dispersion member 16 interposed therebetween. It is arranged on the 3rd.

The operation of the present invention will be described below, including such viewpoints.

That is, in the floor heating system constructed as shown in FIGS. 1 and 2, Joule heat from the heating element 10 such as the heater unit of the heating apparatus 7 is in close contact with the heating element 10 such as the heater unit. The heat is transferred to the configured uniform case body 8 of the upper case, and the heat is further transferred to the lower surface of the floor material 6 in contact with the upper part of the uniform case body 8 of the upper case.

When the floor material 6 is warmed from the lower surface, when the material of the floor material 6 is wood, the thermal conductivity is smaller than that of metal, so that the heat is gradually transferred to the upper surface side of the floor material 6 and the surface of the floor. The temperature rises.

When the temperature of the floor surface rises, heat is radiated in the form of convective heat and heat radiation from the floor surface in a tendency proportional to the difference with the ambient temperature including the air inside the room, and the ceiling facing the floor surface is radiated. The surrounding wall surface is warmed by the surface or its secondary radiation, and the indoor air is also warmed.

Therefore, for example, under an environmental condition where the floor surface temperature is around 27 ° C. and the temperature of the wall surface and the air is around 18 ° C., if there is a person in it, the radiant heat is received from the entire circumference and the feet are warm. You will feel extremely comfortable.

As described above, for the purpose of efficiently heating the floor surface in a uniform heat radiation state from the heating device 7, the vertical expansion / contraction function as shown in FIGS. 1 and 2 is provided. The purpose can be achieved by installing the heating device 7 used for floor heating of the case body which has a flat surface over the entire surface of the soaking case body 8 of the upper case.

[0075]

As described above, according to the present invention, a heat equalizing case body having an upper flat plate shape in which a heating element is provided, a heat shield case body having a lower flat plate shape in which an absorber is provided, and A configuration is provided in which a heating device configured by attaching a heat equalizing case body and the heat shield case body to each other in a vertically expandable / contractible manner is installed by pressing the heating device between floor joists below the floor material and further toward the floor material side. Since the heating device itself has an up-and-down expansion and contraction function, which is composed of elastic materials such as coil springs that are versatile and inexpensive, the overall cost is low, including the construction cost that has been a problem in the past. It is possible to provide an underfloor heating device that is excellent in heat transfer and heat transfer, and it can be expected that the introduction and spread of comfortable underfloor heating will be facilitated.
