Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for effectively performing floor heating.

In general, underfloor heating devices are made by dispersing and mixing carbon powder into a base such as synthetic resin to form a stable cross-linked structure, or by using a planar heating element in which linear heating elements are bent and arranged in a base of an insulating member. It is housed in a mat and formed into a mat shape, and for temperature control, linear or dotted temperature sensors are installed distributed over the entire surface to maintain a predetermined temperature.

Therefore, when a cushion or an ornament is placed on a part of the body, heat dissipation in that part is inhibited and heat is accumulated.
The temperature sensor is activated and the current is cut off. Therefore, the temperature of other parts where heat is dissipated becomes lower than the set temperature, resulting in so-called temperature unevenness, and there is a problem that a sufficient heating effect cannot be obtained.

Furthermore, as mentioned above, underfloor heating simply involves laying a pine-like material on the floor (or surface), and structures that allow heating of the floor itself have not yet been put into practical use except in some special buildings. There is no state.

The present invention has been made in view of the above points, and an object of the present invention is to provide a method for installing floor heating that is easy to install and that can maintain a substantially uniform temperature over the entire surface even when heat dissipation is uneven as described above. With the goal.

The present invention will be described below based on embodiments shown in the drawings.

First, receivers 2 are arranged at required intervals on a floor surface 1, and the floor surface 1 is divided into a plurality of compartments 5a, 5b, 5c...
... (hereinafter collectively referred to as simply 5). The receiver 2 is made of a material that has the required rigidity even when heated, such as iron or aluminum.
Although the illustrated example shows a structure in which both 3 and 4 are separate and connected, they may be constructed as an integral structure. Moreover, the above-mentioned interval is determined by the rigidity of the top plate 12 placed on the upper part of the receiver 2, as will be described later.

Next, a bottom plate 6 with a heat insulating material is provided for each compartment 5.
and place the corresponding rear heating element 7 on the pedestal 3 of the receiver 2.
Place it on top and pass it over. In this case, the pedestal 3 is made to protrude slightly from the upper surface of the bottom plate 6, thereby forming a minute gap 8 between it and the bottom plate 6.

The planar heating element 7 has a well-known structure, for example, a structure in which conductive particles such as carbon are dispersed and mixed in a base of synthetic resin, or a structure in which carbon powder and synthetic resin such as polyethylene are mixed. It can be mixed and melted and made into a cross-linked structure by electron beam irradiation, or it can be a structure in which nichrome wire is appropriately bent and buried in an insulating heat-resistant material. The temperature is maintained at a predetermined temperature by a temperature control circuit (not shown).

Further, the support 4 of the receiver 2 has a gap 10 of a required height between it and the top plate 12 placed on the top of the support 4.
The support column 4 is formed with a through hole 11 for communicating between adjacent compartments 5, 5. The through hole 1 in the example shown
1 shows an example in which the upper end is formed by a notch, but as shown in FIG. 4, a through hole 11'' may be formed with a perforation.

Next, the top plate 1 is placed on the receiver 2 over the entire floor surface.
2 is laid, and a gap 10 is formed between the sheet heating element 7 and the sheet heating element 7.
The construction is completed by forming a top plate 12 and covering the upper surface of the top plate 12 with an outer cover 14.

The top plate 12 has an electric heating structure so as to efficiently conduct heat from the planar heating element 7 to the outer cover 14. That is, it is preferable to use a good thermal conductor such as iron or aluminum, but it is also possible to use a poor thermal conductor such as a wooden board or synthetic resin. However, in this case, a large number of through holes 13 are drilled on the entire surface,
The radiant heat from the planar heating element 7 is directly irradiated onto the outer sheath 14 through the through hole 13, and the heated air in the gap 10 is in direct contact with the outer sheath 14, and the outer sheath 1
4 and discharged into the room.
Note that in the case of a good thermal conductor, the through holes 13 are not necessarily required, but since the heated air directly contacts the outer sheath 14 and is discharged into the room through the outer sheath 14, the through holes are similarly provided. It is preferable to provide 13.

The above-mentioned outer covering 14 may be suitably selected depending on the purpose of use, such as a carpet, a carpet, or a tatami mat, and may be constructed of a floorboard made of a synthetic resin board when used in an office or the like.

The above construction example shows a construction method in which the top plate 12 is placed on the receiver 2 and then the upper surface of the top plate 12 is covered with the outer sheath 14. It is also possible to have an integral structure and place it on the receiver 2.

The above embodiment is an example in which the receivers 2 are arranged at predetermined intervals to form compartments 5a, 5b, etc., and then the bottom plate 6 and the planar heating element 7 are housed in each compartment. However, depending on the properties, strength, etc. of the bottom plate 6 and the planar heating element 7, these may be spread over the entire floor surface in advance.
The receiver 2 may be attached thereon.

As described above, according to the present invention, a top plate with a heat transfer structure is provided with a gap between it and the planar heating element, and this is covered with an outer cover, so that a part of the outer cover has heat defects such as cushions. Even if conductors are overlapped and a heat dissipation defect occurs, the air in the gap will move freely, so the top plate and outer cover will not accumulate heat, and the entire floor surface will always have a uniform temperature. , and construction is extremely simple. Furthermore, the heating is hygienic because it uses electric heat, and when cooling is required, such as in the summer, it is also possible to cool the floor by introducing cold air into the gap by appropriate means.
