Description

The present invention relates to an improvement of a floor member having a honeycomb structure for housing (referred to as a honeycomb core floor member), and more specifically, a heating wire in which a hole penetrating a honeycomb wall of a honeycomb core is formed and an insulating material is coated therein. The present invention relates to a honeycomb core floor member for floor heating that can increase heating efficiency, achieve energy saving, and is easy to construct.

Conventionally, an aluminum honeycomb core has been used as a flooring material for floor heating because of its strength and heat insulation. The structure most commonly used at present is illustrated in FIG. An electrothermal heating sheet 31 is applied to the lower floor, and the honeycomb core flooring 11 is adhered thereon using an adhesive 32.

Since the honeycomb core material 11 has poor thermal conductivity, the conventional type having a long heat conduction distance between the electrothermal heating sheet 31 and the surface material 12 has poor thermal efficiency and takes time to warm up. Moreover, since a gap is easily formed between the heating sheet 31 and the honeycomb core flooring 11, the thermal efficiency is deteriorated. Furthermore, although the electrothermal heating wire 33 is wired on the honeycomb core side of the electrothermal heating sheet, since the insulator inhibits heat conduction, the thermal efficiency is poor and it takes time to warm up.

FIG. 9 is a graph illustrating the above items. The broken line b in FIG. 10 shows the temperature distribution during the conventional floor heating. In order to increase the surface temperature of the surface material 12, the surface material 12, the honeycomb core 11, the electrothermal heating sheet 3 and Since there is a thermal resistance between the honeycomb core and the honeycomb core side of the electrothermal heating sheet 3, it is necessary to increase the temperature in order to compensate for this. Finally, it is necessary to raise the temperature of the heating element 7. On the other hand, even if an electrothermal heating sheet and a heat insulating material are used on the back side, the temperature becomes high and heat radiation is large. From the above, it is obvious that the floor heating method using the conventional honeycomb core has poor thermal efficiency and takes time to warm up.

Furthermore, in the heating floor construction, since the honeycomb core is constructed after the heating heating sheet is constructed, it takes time and labor. In addition, when the heating / heating sheet breaks down, it is not economical because the entire floor construction is required.

FIG. 7 shows an example of the structure of a heating floor member using another honeycomb core that has improved this defect. In this structure, the electrothermal heating sheet 3 is attached to the surface of the honeycomb core 11 and a surface material is attached thereon.

In this structure, the thermal efficiency is good, but if the surface material is a hard and brittle material such as natural stone flakes or tiles, the electrothermal heating sheet is soft and elastic, so there is a high possibility that the surface material will crack if a load is applied to the floor . Also, if the surface material is soft, such as a vinyl sheet or a carpet, placing a heavy-pointed object or heavy object on the floor may damage the electrothermal sheet, resulting in a risk of fire or the like.

FIG. 8 shows a heating floor member using still another honeycomb core. It is dispersed in the cells of the honeycomb and the heating element on the lump is embedded. Considering the size and thickness of the cell, the number of heating elements becomes very large, which increases the number of construction steps and costs.

In addition to electric heat, floor heating includes heating using hot water or a heat medium. In either case, the liquid is circulated and heated, but a hot water facility, a heat exchange facility, a liquid feeding facility, and piping are necessary, which is expensive. Furthermore, since the piping is thick, it is difficult to construct such as embedding the honeycomb core. For this reason, the honeycomb core of the piping part is cut out or the piping part is pressed. This processed portion has a reduced strength and the purpose of using the honeycomb core is lost.

In addition, the following patent document can be mentioned as a well-known technique relevant to this invention.

  JP-A-56-97799   JP 07-32518 A   Japanese Patent Laid-Open No. 11-83049   JP 2002-228174 A   JP 61-134030 A   JP 02-18046 A   Japanese Patent Laid-Open No. 05-94617   Japanese Patent Application Laid-Open No. 07-38404

The present invention has a problem to solve such problems of honeycomb core floor heating according to the prior art, that is, the present invention seeks to obtain simple construction, low construction cost, improved thermal efficiency and rapid temperature rise in floor heating. There is a solution to the problem.

Means for solving the problem

The present invention has been developed to solve the above-described problems. A small hole having a diameter of 5 mm or less that penetrates through the honeycomb wall of the honeycomb core is formed in the honeycomb core body, and the hole is covered with an insulating material. An object of the present invention is to provide a floor heating member that has a structure in which a heat ray (seeds heater, cord heater, etc.) is embedded, can exhibit a heating effect faster, and can reduce heating energy.

Furthermore, in the floor heating member, floor surface materials such as tiles, natural stones, artificial stone bricks, glass, wood (flooring), vinyl tiles, carpets, carpet tatami mats, etc. are processed thinly and pasted on the upper surface of the honeycomb core body. It is a thing.

The invention's effect

In the present invention, a hole is formed inside the honeycomb core, and the heating wire is passed through the hole. Therefore, there is no gap between the heating wire and the honeycomb core, and since it is close to the upper surface to be used, Efficient heating can be provided rather than heating.

FIG. 9 is a graph illustrating the thermal effect of the present invention in comparison with the conventional structure. Looking at the temperature distribution (a solid line) inside the flooring according to the present invention, when the temperature of the surface material 12 is the same as that of the conventional floor heating, the temperature a of the heating element 7 at the center of the honeycomb core is the heat generation of the conventional type. Obviously, it is lower than the temperature b of the body 33. Moreover, the temperature of the heating member back side is also low. For this reason, the floor heating according to the present invention warms up faster than the conventional floor heating, and has good thermal efficiency and energy saving.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a honeycomb structure diagram. Honeycomb 1 is formed by processing aluminum into a honeycomb shape, and a strong structural material can be manufactured with a small amount of material. Moreover, since the honeycomb structure is hollow, heat conduction is not good.

FIG. 3 is a structural diagram of the honeycomb core 11, which has a structure in which an aluminum single-side plate 2 and an opposite-side plate 3 are attached to the honeycomb 1 to prevent lateral deformation, and is widely used for flooring. . In the present invention, the honeycomb core is improved to provide a floor heating member with good thermal efficiency.

  4 and 5 relate to an embodiment of the present invention, FIG. 4 is a schematic diagram of a honeycomb core floor member for floor heating according to the present invention, and FIG. 5 is an oblique view of the honeycomb portion. As shown in FIGS. 4 and 5, the holes 4 are penetrated at right angles to the wall surface 10 of the honeycomb structure 1. Assuming that a heavy object is placed on the floor, the hole 4 has a diameter of 5 mm or less. The machining position of the hole may be anywhere in the wall surface 10, but the upper and lower and left and right centers of the plane are preferable in terms of strength.

Although a detailed structure is shown in FIG. 5, the heating wire 5 in which the resistance wire 7 is covered with the insulating material 8 is passed through the processed hole 4. In order to prevent the heating wire 5 from being damaged by the honeycomb, it is preferable to cover the protective coating 9 such as a stainless steel pipe or an aluminum pipe.

When a hole is made in the honeycomb core, the strength of the honeycomb core decreases. However, when the diameter is 5 mm or less, there is little decrease in strength and there is no problem in use, so the through-hole 4 has a diameter of 5 mm or less.

FIG. 4 shows a situation where the coated heating wires are wired. All the heating wires 5 are wired inside the honeycomb core, and the terminals 6 are exposed outside the honeycomb core. The terminal 6 is connected to the controller 25, the input power is controlled by an electronic control device, and the floor heating temperature is controlled. It is natural to take safety measures such as installing a thermostat in the middle of wiring to prevent overheating, installing a thermal fuse to prevent fire, and grounding directly from the honeycomb core to prevent electric shock. Further, the temperature control can be performed by installing the thermometer detection end in the honeycomb core instead of the input control.

Fig. 1 shows a honeycomb core floor member for floor heating that has been implemented. Floor surface of tile, natural stone, artificial stone, brick, glass, wood (flooring), vinyl tile, carpet, carpet, tatami mat, etc. This is a floor heating member to which a material 12 is attached. A comfortable living space is formed by using the floor surface material 12 according to the application for housing. In addition, by using a honeycomb core, an expensive surface layer material can be thinned and used. Considering floor heating, the thinner one has better heat conduction, so it warms faster, improves thermal efficiency, and saves energy.

FIG. 6 shows an embodiment in which a flooring floor is constructed in a 6 tatami western room. A flooring material having a thickness of 5 mm is pasted and applied to a honeycomb core having a size of 1 tatami mat incorporating a heating wire. Wiring is performed from the power supply 24 and power control is performed by the electronic temperature controller 25. The output is distributed to each of the six honeycomb cores by the wiring 23. In FIG. 6, only one pair of wirings is depicted, but the honeycomb cores are individually wired independently, so that only the necessary honeycomb cores can be heated. In addition, each honeycomb core can be set to a different temperature. This heats only the necessary part as necessary, and is highly effective for energy saving.

FIG. 7 shows an embodiment constructed on the bathroom floor. The purpose is to prevent the coldness of the soles of the feet when entering the bathroom and at the same time to dry the bathroom. The bathtub 26 is made of natural stone, and the surface material 21 of the wash basin is made by slicing the same natural stone as that of the bathtub. The temperature of the natural stone, that is, the temperature of the honeycomb core is controlled by wiring from the power source 24 and controlling the power by the electronic controller 25. Because it is a place where hot water is used, all wiring and equipment must be waterproof, and at the same time ground from the honeycomb core to prevent people from electric shock.
