Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, it is well known that floor heating is an extremely comfortable and best heating method once it is warmed up, but recently, for the sake of environmental hygiene in the interior of a house, the floor is made of a wooden floor. It is often finished with floor material for 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, floor heating between joists is a method of arranging a number of joists that constitute the underfloor and supporting the floor material, and installing a heating device between the joists. If this is not possible, there is a possibility that the temperature rise will be poor and the floor heating will be inferior in performance because the temperature distribution over the entire floor surface will be uneven.

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 a panel provided under a floor plate, that is, the entire heating device, the lower part of the panel is mainly used for adjusting heat transfer. It is known to adjust the thickness of the air bag provided in the air bag 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 heat storage type floor heating, when a heavy object is used, the weight becomes heavy, so naturally large elastic force and pressure are required.

[0008]

As described above, conventionally,
Since the whole heating device for floor heating is supported from below, the scale of the entire device for obtaining the effect becomes large, and as a result, the cost becomes high, so there is a problem that it is difficult to introduce it costly despite good floor heating. .

As described above, there has been no means for making the lower surface of the floor material and the heater unit in a simple and uniform contact at low construction cost.

In view of the above, the object of the present invention is to provide a structure for effectively performing heat transfer and heat transfer in the floor heating direction in a heating device for floor heating with a new system for the internal structure of the heating device. By introducing, the same effect as above can be obtained without supporting the whole heating device from the bottom, the construction scale of the whole heating device for floor heating is small and simplified, and the construction cost is simplified. It is to reduce the total cost including the above and to spread the floor heating system.

[0011]

In order to solve the above-mentioned problems, the present invention has a heating device to be installed between the joists under the floor material, and the heating device can be divided into an upper case and a lower case. At the same time, the heater unit is provided internally, and the upper case and the lower case are configured so as not to come off, and the elastic body having a vertically expanding / contracting function is provided internally between the upper case and the lower case.

Further, a plurality of elastic bodies having a vertical expansion / contraction function are dispersedly arranged between the upper case and the lower case, and the elastic bodies are coil springs.

Further, stoppers are provided at the side end portions of the upper case and the lower case to prevent the upper and lower cases from coming off.

In addition, a spacer for positioning the elastic body and for insulating and soundproofing is provided in the heating device in which the heater unit and the elastic body are provided.

Further, the heater unit is provided with a heating element having a positive temperature characteristic.

Further, the heater unit is supported from below by an elastic body and is brought into close contact with the inner surface of the upper case of the heating device.

Further, the vibration absorption and sound absorbing function is added to the heater unit.

[0018]

According to the above-mentioned means for solving the problems, according to the above-described means of the present invention, by providing a plurality of elastic bodies in the upper and lower cases containing the heater unit and the like, a heating device having a vertical expansion and contraction function is provided. Only the upper surface of the upper case, which is in close contact with the heater unit, can easily and reliably make contact with the lower surface of the floor material to be constructed.

You can also

Reference numeral 7 is a heating device for floor heating, which is installed between the joists 4 below the floor member 6, and 8 is an upper case which constitutes the outer shell of the heating device 7, and is a rust-proof metal plate. However, depending on the specifications of the heat generating element and protection from external force, it functions as a soaking plate that makes the temperature distribution uniform.

Reference numeral 9 is a lower case made of the same material as that of the upper case 8, and 9a is a stopper provided at an end of the lower case 9, which faces a portion of the lower case 9 facing the stopper 9a. A stopper 8a is provided at the end of the upper case 8. Both stoppers 8a and 9a are in a non-pressurized state as shown in FIG.

Reference numeral 10 denotes a heater unit which is provided in close contact with the upper case 8 and has a built-in heating element whose surface including the periphery is electrically insulated. A heating element (PTC heater) having characteristics is suitable.

That is, when the heater unit 10 is laid on the lower portion of the floor material 6 in a large area of a room where people live, the surface of the floor material 6 is often covered with rugs and furniture and is thermally blocked. become.

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 effect of suppressing the temperature rise can be expected.

Further, the heater unit 10 is provided with a function of absorbing vibrations and sounds from the floor material 6, so that it is necessary to make a decision in consideration of a soundproof effect to the floor when it is installed in an apartment house or the like. There is.

Numeral 11 is a spacer which is provided in the lower case 9 of the heating device 7 and has the functions of positioning, insulating and soundproofing the elastic body 12, and when the central portion of the upper case 8 is pushed from above, the upper case 8 is pressed. 8 has a function of protecting the heater unit 10 by minimizing the deformation.

Reference numeral 12 denotes an elastic body, which is provided between the insides of the upper case 8 and the lower case 9 in a necessary 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 this elastic body 12, the upper case 8
The lower case 9 becomes a case body that expands and contracts in the vertical thickness direction, and if the heating device 7 of the case body that expands and contracts under the floor in the structure as shown in FIGS. 1 and 2 is installed in the storage unit designed within the expansion and contraction dimension. Thus, it becomes easy to bring the entire surface of the upper case 8 of the heating device 7 into contact with the lower surface of the flooring material 6 in a good state.

An elastic body 12 of a coil spring is provided in the case body.
The elastic body 12

In order to improve the thermal contact between the heater unit 10 and the upper case 8, it is effective to support the elastic body 12 from the lower portion of the heater unit 10.

Also, depending on the method of supporting the elastic body 12 from the lower portion of the heater unit 10, a low-cost construction is conceivable in which sufficient thermal coupling can be obtained without using an adhesive or the like for the entire surface of the upper case 8 to form a close contact. To be

Reference numeral 13 is a heater unit 10 and a spacer 11.
It is the space in the case between and has a function of heat insulation.

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 plurality of elastic bodies 12 housed between the upper case 8 and the lower case 9 are also in a compressed state, and the space 13 in the case is also in a compressed state. This compressed state after installation is the upper and lower stoppers 8a, 9
Since a does not come into contact with each surface, the upper case 8
The heat transfer from the lower case to the lower case 9 is reduced, and the heat leakage in the downward direction is reduced.

On the other hand, in the heating device 7 in the free state before construction shown in FIG. 3, since the elastic members 12 incorporated therein are not pressed from above and below, the thickness of the heating device 7 is above and below. The stoppers 8a of the upper case and the stoppers 9a of the lower case, which are provided at the ends of the upper case 8 and the lower case 9, respectively, swell to a state in which they are in contact with each other, and the thickness is increased.

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

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

That is, in FIGS. 1 and 2, on the scraping material 3 lined with the heat insulating material 2 between the large pulling materials on the large pulling material 1,
The joists 4 are arranged at regular intervals. The heat insulating material 5 between the joists 4 is provided between the adjacent joist materials 4 on the scraping material 3, and a required number of heating devices 7 are arranged on the heat insulating material 5 between the joist 4 to make electrical connection (not shown). After that, the floor material 6 is fixed to the joist 4 to complete.

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

Since the installation allowable dimension is wide as described above, the front surface of the upper case 8 of the heating device 7 and the back surface of the floor material 6 are separated from each other even if the dimensions of the joist 4 and the insulation 5 between the joists slightly vary. It is possible to make uniform contact over the entire surface.

Although not limited to the floor heating system of the present invention, in order to efficiently warm the room in which the floor heating is installed, the heating device 7 for floor heating and the components around it are basically the same as described above. It is important to prevent the heat flow from the heat source such as the heater unit 10 from flowing into a room other than the room for heating as much as possible. In other words, it is necessary to reduce the heat resistance in the room direction as viewed from the heat source and increase the heat resistance in the opposite direction to the room.

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

That is, in the floor heating system configured as shown in FIGS. 1 and 2, Joule heat from the heater unit 10 of the heating device 7 is transferred to the upper case 8 which is in close contact with the heater unit 10. Then, the heat is further transferred to the lower surface of the floor material 6 in contact with the upper portion of the upper case 8.

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 such that the floor temperature is around 27 ° C. and the temperature of the wall surface and air is around 18 ° C., if a person is present in the environment, radiant heat is received from the entire circumference and the feet are warm. You will feel extremely comfortable.

For the purpose of efficiently warming the floor surface in a state where the heat from the heating device 7 is uniformly dissipated as described above, the vertical expansion and contraction as shown in FIGS. 1 and 2 of the present invention. The purpose can be achieved by installing the heating device 7 which has a function and is used for floor heating of a case body which has a flat surface over the entire surface of the upper case 8 and which expands and contracts.

[0051]

As described above, according to the present invention, since the heating device itself having the versatile and inexpensive elastic body such as the coil spring has the function of expanding and contracting in the vertical direction, It is possible to provide a heating device for floor heating that is excellent in heat transfer and heat transfer, including the construction cost, which was a problem of .
