Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a heat-generating floor material incorporating a planar heating element, which has improved temperature control function and improved durability.

[Prior art and its problems]

Conventional heat-generating flooring materials have internal thermistors and fuses to control temperature and prevent overheating. However, heat-generating flooring made of laminated surface materials such as wood materials has problems due to the thickness and poor thermal conductivity of the surface materials.
It took a long time to heat up to the surface, and it was difficult to control the temperature, causing discomfort due to poor electrical efficiency and poor responsiveness.

In other words, the thermistor and fuse described above are installed by making a recess directly in the base material and burying them, but it is difficult to control the temperature of the base material by sensing the temperature of the base material, which is full of heat, or to turn off the thermistor. The disadvantage is that the temperature is sensed locally, resulting in a large temperature difference from the surface of the flooring material, and temperature control is not accurate. In addition, if the surface material of the floor is made thinner in order to increase the temperature faster, it will lack pressure resistance and rigidity, which may damage the surface heating element and control parts, and the floor will flex significantly, making walking unstable. Ta.

〔the purpose〕

The present invention was devised in view of the drawbacks of the conventional examples, and its purpose is to provide a heat generating flooring material that can more accurately control temperature without impairing durability or rigidity. .

[Means for solving problems]

In order to solve the problems of the conventional example, the present invention includes: A frame material 2 is arranged around the periphery of the floor material body 1, a surface heating element layer 3 is provided on the surface side of the floor material body 1, and the floor material A long reinforcing material 4 with excellent thermal conductivity is located approximately in the center of the main body 1 and directly below the surface heating element layer 3.
A heat insulating material 7 is arranged on both sides of the reinforcing material 4, and a control device 5 is brought into contact with the inner ceiling surface of the reinforcing material 4, with the lower part thereof being a hollow part.

; is adopted as a technical means.

[Function] Electricity is applied to the surface heating element layer 3 to raise the temperature of the surface material 6.

At the same time, the heat of the surface heating element layer 3 is transmitted to the reinforcing mold material 4, but because it is hollow and has good thermal conductivity, heat is difficult to accumulate and is less affected by local variations. 4, the temperature of the surface material 6 can be detected relatively stably, and accurate temperature control is possible.

In addition, although a load is applied to the flooring material A, its strength is high because the reinforcing material 4 is provided in the center, and even if the surface material 6 is made thin, it does not bend easily and will not be damaged by loading or walking. Does not cause anxiety.

At the same time, since the control device 5 is in contact with the shape material 5, there is no possibility that these will be damaged by external impact or external load.

〔Example〕

The present embodiment will be described below with reference to the drawings.

The floor material body 1 is composed of a surface material 6, a surface heating element layer 3, a frame material 2, a mold material 4, a heat insulating material 7, a backing material 8, and a control device 5 for controlling the surface heating element layer 3. .

The back material 8 is made of wood or inorganic board such as plywood or silica board, and the surface material 6 is made of veneer laminated board or
It is composed of laminated decorative boards such as WPC treated decorative boards.

The reinforcing material 4 is made of metal such as aluminum or steel, or resin such as hard vinyl chloride or acrylic, and has a substantially U-shaped cross section.It is located in the center of the floor material body 1 with the opening facing downward, and has a surface heating element layer. It is arranged so as to be in contact with 3. Here, since the center of the floor material body 1 is supported by the shape material 4, the thickness of the surface material 6 can be reduced to approximately half or less than that of conventional floor material 6 without any support, without affecting the strength or deflection. Not only is the heat conduction to the surface A faster, which is preferable, but the overall thickness of the flooring material A can also be made thinner.
If the surface material 6 is assumed to be 3 mm, the total thickness is 15 mm, which is the same thickness as conventional wooden flooring, making it possible to locally install the heat-generating flooring material A, making it easy to use.

The control device 5 includes a thermistor 5a and a fuse 5b, which are arranged in plural in a hollow part 4a formed of a molded material, and are connected to each other by a lead wire 5c formed by converging the connection wire of the surface heating element. When the control device 5 is placed inside the hollow portion 4a, the thermistor 5a is brought into contact with the mold material 4 to form a space on the lower side (opening side). This improves heat sensitivity.

The frame material 2 is made of wood, plywood, or the like and is disposed around the peripheral edge of the floor material body 1, and female fruit and male fruit are formed on the outside of each of two opposing sides.

The heat insulating material 7 is made of wood, inorganic, or foamed synthetic resin such as insulation board, glass wool, asbestos sheet, rock wool board, foamed urethane, or foamed phenol.
Filled between.

The planar heating element layer 3 is formed by laminating resin layers on the front and back sides of a planar heating element to perform waterproof treatment, and is disposed on the lower surface of the surface material 6. Furthermore, an insulating sheet or a heat-uniforming plate is appropriately laminated on the front and back surfaces of the surface heating element layer 3 to improve safety and thermal efficiency.

Then, electricity is applied to the surface heating element layer 3 to raise the temperature of the surface material 6. At the same time, the heat of the surface heating element layer 3 is transmitted to the reinforcing mold material 4, but because it is hollow although the surrounding area is covered with the heat insulating material 7 and because it has good thermal conductivity, it is difficult for heat to accumulate and is less affected by the surrounding heat. Since it is in continuous contact with the surface heating element layer 3, even if there is some temperature unevenness in the surface heating element layer 3, it is transmitted to the control device 5 in an average manner, so that the temperature change of the surface heating element layer 3 is is detected relatively stably and turned on and off when the surface material 6 reaches a predetermined temperature, thereby achieving accurate temperature control.

In addition, although a load is applied to the floor material A by walking or carrying cargo, it does not bend because the reinforcing section 4 is provided in the center, so walking safety is not impaired.

〔effect〕

As mentioned above, the present invention has a frame material arranged around the periphery of the flooring body, a surface heating element layer inside the surface side of the flooring body, and a plane heating element layer approximately in the center of the flooring body. Directly below the layer is a long reinforcing material with excellent thermal conductivity, and heat insulating material is placed on both sides of the reinforcing material, and the control equipment is brought into contact with the internal ceiling surface of the reinforcing material, with the lower part being a hollow section. Therefore, the control parts are in contact with the mold material, which has good thermal conductivity, and in addition, because a space is formed inside the mold material, the influence of the heat capacity of the back material and side insulation material, and the local heating element of the surface heating element. It has the advantage of being less susceptible to temperature fluctuations, being able to feel the temperature of the surface heating element layer relatively stably, and being able to quickly turn on and off when it reaches a predetermined temperature, making it easy to control the temperature. . In particular, since the reinforcing material is long,
The average temperature of a wide area of the planar heating element can be measured, and the temperature can be accurately controlled. Furthermore, since the control parts have good pressure resistance and are in contact with a molded material located approximately in the center of the flooring body, not only can the surface material be made thinner and the heating time can be shortened, but the strength is also improved. The control parts will not be damaged by impact or load from the surface side, and since the entire surface material is supported in the center, there will be less flexing even if the surface material is made thinner, preventing damage due to the load of the cargo and weight. There is also the advantage that there is no bending caused by this, and there is no fear of walking anxiety.

As described above, it is possible to provide a heat-generating flooring material with accurate temperature control, short temperature rise, and good durability.
