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, in all of the above-mentioned conventional examples, the first purpose is to speed up heat transfer and heat transfer, and therefore, the entire heating device provided at the bottom of the floor plate is subjected to force from below. It aims to reach the purpose of the period.

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, the prior art is as follows.
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 is no means for making the lower surface of the floor material and the heater unit contact with each other easily and uniformly at a low construction cost.

In view of the above, the object of the present invention is to effectively heat transfer and heat transfer in the floor material direction in a heating device for floor heating, and to make a partial temperature distribution on the floor surface, which is a heating surface, uniform. By introducing a new method into the internal structure of the heating device, the same effect as described above can be obtained without supporting the entire heating device from below, and the overall scale of the heating device for floor heating is small. By simplifying and facilitating construction, it is possible to reduce the overall cost including construction cost 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. In addition, in a heating device for floor heating, a heater unit is internally provided, and the upper case and the lower case are configured so as not to come off, and an elastic body having a vertically expanding / contracting function is internally provided between the upper case and the lower case. A plurality of convex portions that are integrated with the upper case are provided on the upper case on the contact surface side with the floor material, and a space having a certain dimension is provided between the contact surface between the floor material and the upper case.

Further, a heating device installed between the joists under the floor material and the heating device can be divided into an upper case and a lower case, and a heater unit is internally provided, and the upper case and the lower case are further installed. In a heating device for floor heating in which an elastic body having a vertically expanding / contracting function is provided between the upper case and the lower case, the upper case is attached to the upper case on the contact surface side with the floor material. A plurality of convex portions, which are separate members from the case, are provided, and a space having a certain size is provided between the floor material and the contact surface between the upper case and the case.

Further, a mesh-shaped space forming material is interposed in the convex portion of a member separate from the upper case.

In addition, a space forming material having a plurality of projections and divided into planes is interposed between the projections of the member different from the upper case.

[0015]

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 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 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 of the structure as shown in FIGS. 1 to 4 is installed in the storage part designed within the expansion and contraction dimension. The upper surface side of the upper case 8 of the heating device 7 can be easily brought into contact with the lower surface of the floor material 6 in a uniform state according to the surface state of the upper surface side of the upper case 8.

Further, the heater unit 10 and the upper case 8 are generally bonded mechanically or with an adhesive agent or the like. In order to keep the thermal contact between them better, the elastic body 12 is attached to the heater unit 10. Supporting from the bottom is an effective structure in which the degree of adhesion between the two is improved.

Further, depending on the supporting method from the lower part of the heater unit 10 of the elastic body 12, for example, the number of supporting or the supporting position, thermal bonding can be performed without using an adhesive or the like on the entire surface of the close-constituting means with the upper case 8. A sufficiently low-cost configuration is conceivable.

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.

3 and 4, reference numeral 14 denotes a convex portion formed at the end of the upper case 8 which is integrally formed with the upper case 8 and is formed by press working or bending at the time of manufacturing the upper case 8. It is what is done.

Reference numeral 15 denotes a convex portion formed at the end portion of the upper case 8 which is provided by non-integral processing with the upper case 8. For example, another member is provided by welding, bonding, screwing, caulking or the like.

In order to have the same function as the convex portion formed at the end of the upper case 8, the upper surface of the upper case 8 is divided into a mesh-like space forming material 17 or a large number of convex portions 18. The space forming material 17 may be provided integrally or as a separate member.

In the case of the present embodiment, the convex portions 14 and 15 formed at the end of the upper case 8 have a temperature distribution in the form of a dot or a line, or a plurality of mechanical strengths or rigidity of the upper case 8, etc., if necessary. There are some places.

Reference numeral 16 denotes a space generated between the floor material 6 and the upper surface side of the upper case 8 when the heating device 7 is installed between the joist 4 and the lower portion of the floor 6, and the size (gap) of the space is the upper case. It depends on the design dimensions of the protrusions 14 and 15 formed at the end of No. 8.

1 and 2, the heating device 7 is installed in a pressurized state 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, the thickness of the heating device 7 depends on the elasticity of the plurality of built-in elastic bodies 12 because it is not pressed from the vertical direction. 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 FIG. 1 and FIG. 2, on the discarding material 3 lined with the large-pull insulation material 2 on the large-pull material 1,
The joists 4 are arranged at regular intervals.

A heat insulating material 5 between the joists 4 is provided between the adjacent joist materials 4 on the scraping material 3, and the heat insulating material 5 between the joist 4 is provided.
A required number of heating devices 7 are arranged on the upper part and electrically connected (not shown), and then the floor material 6 is fixed to the joist 4 to complete the process.

Here, when the heating device 7 is inserted between the adjacent joists 4, the size of the heating device housed between the heat insulating material 5 between the joists and the floor material 6 is such that the upper part of the upper case 8 of the heating device 7 is on the floor. Material 6
Heating device 7 in a non-pressurized state so that it makes light contact with the back of the
Slightly smaller than the thickness (maximum thickness) and larger than the maximum compression dimension (minimum thickness).

Since the width of the allowable installation dimension is large 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 heat insulating material 5 between the joists slightly vary. It is possible to make uniform and reliable contact.

Although not limited to the floor heating system of the present invention, in order to efficiently heat 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 conversely increase the heat resistance in the direction opposite 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. 3 and 4, the 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. Further, the heat is transferred to the upper surface of the upper case 8 to the lower surface of the flooring 6 through the upper space 16 of the case.

When the floor material 6 is warmed from the lower surface, when the floor material 6 is made of 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 heat radiation and convective heat 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 wall and air temperatures are around 18 ° C., if there is a person in it, radiant heat is received from the entire circumference and the feet are warm. You will feel extremely comfortable.

On the other hand, only for the purpose of efficiently heating the floor surface by the heat from the heating device 7, the upper and lower cases 8 have a function of expansion and contraction in a vertical direction, and the entire surface of the upper case 8 is flat and flat. Although the purpose can be achieved by installing a heating device 7 used for floor heating of a case body that expands and contracts with a surface, on the other hand, how the heat is transmitted from the heating device 7 to the floor material 6 is Since the faces are in direct contact,
Even in the same floor material 6, there is a difference in the temperature of the floor surface between the portion directly above the heating device 7 and the portion directly above the joist 4 without the heating device 7, resulting in partial temperature unevenness and dissatisfaction with the warming feeling. ,
Alternatively, the floor material 6 may be adversely affected.

From the above, when it is desired to reduce the partial temperature unevenness even if the temperature rise rate of the floor surface is sacrificed to some extent, as shown in FIGS. 3 and 4, the convex portion of the upper case 8 is formed on the surface of the upper case 8. By using the heating device 7 provided with 14 or the convex portion 15, when the heating device 7 is installed, a space 16 on the case which is generated between the convex portion 14 and the rear surface of the flooring 6
However, due to the effect of an indirect heat transfer method that disperses and transfers heat by the function of a heat buffer or the function of convective heat, etc., the heating device 7 is installed on the entire floor material 6 in close contact. From above, the part directly above the heating device 7 and the joist 4 without the heating device 7
The temperature difference with the portion directly above the floor is reduced, and the partial temperature difference on the floor surface is reduced, which improves temperature unevenness.

Further, the heating device 7 itself can easily and reliably provide a dimensionally uniform space without performing a process for providing a space for the joist 4 and the floor 6 which is troublesome.

[0056]

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 inexpensive overall, including the construction cost, which was a problem of The effect of facilitating introduction and diffusion can be expected.
