Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling heating unit, a heating method and a heating device.

[0002]

2. Description of the Related Art Conventionally, a stove has been used for heating a room.
Various heating devices such as warm air heaters, air conditioners, electric carpets, and floor heating systems are used.

The stove is easy to install and relatively inexpensive, but it occupies a portion of the floor space and can cause burns if it directly touches the heating surface or a fire if it falls. Since the hot air heater and the air conditioner use hot air, there is no risk of burns or fire, and since they are attached to the wall of the room, they do not occupy a part of the floor space. However, with warm air, dust, dust,
Mite and bacteria may circulate in the room and pollute the air in the room.

Electric carpets are easy to install and relatively inexpensive, do not occupy a portion of the floor space,
You don't have to worry about air pollution, but you can't get the entire room warm. Also, if an object is placed directly on the heat generating surface, the temperature of the object becomes very high. The floor heating system does not occupy a part of the floor space and does not worry about air pollution, but it requires large equipment and construction, and is expensive. Further, since heat energy is applied to the floor surface through the thick floor board, it takes time to warm up.

[0005]

As described above, the conventional heating devices have their respective advantages and disadvantages, but they have the common point that they mainly use heat conduction or heat convection.

The stove, warm air heater and air conditioner warm the air in the room and warm the human body by convection of warm air. Further, in the electric carpet and floor heating system, the legs of the human body are directly heated by heat conduction.

When the air is warmed, warm air flows to the upper part of the room and cold air flows to the lower part of the room. Therefore, the conventional heating device inevitably needs to be installed in the lower part of the room or to force the air to circulate in the room. This causes problems of occupying space in the room, safety problems such as burns and fires, and hygiene problems due to air circulation.

Therefore, the object of the present invention is to occupy a part of the floor space, to be free from hygiene and safety problems, to be inexpensively and easily installed, and to be effective for the human body. It is to provide a ceiling heating unit, a heating method, and a heating device that can be warmed efficiently.

The ceiling heating unit according to the first to eleventh inventions,
In the heating method and heating device, when the far-infrared radiation sheet attached to the ceiling is energized, far-infrared radiation sheet radiates far-infrared radiation, and the radiant energy goes straight to reach the human body in the room and is mostly absorbed there. It As a result, the molecular motion inside the human body is activated and the temperature rises. In addition, far infrared rays are directly absorbed not only by the human body but also by most clothes.

As described above, since the far infrared rays directly give heat energy to the inside of the human body or clothes without heating the air, the human body can be efficiently warmed in a short time with a small amount of electric power.

Since the far infrared radiation sheet is attached to the ceiling, there is no problem that a part of the floor space is occupied for heating. In addition, since the human body does not come into contact with the far-infrared radiation sheet, safety problems such as burns and fires do not occur. Further, since the inside of the human body is directly heated by the radiant energy of far infrared rays without passing through the air, it is not necessary to forcibly circulate the air, and the sanitary problem due to contaminated air does not occur. Since the far-infrared radiation sheet is thin, lightweight, and not bulky, it can be easily attached to the ceiling and can be easily attached even after building the building. Moreover, the structure is simple, and it can be manufactured at low cost.

In particular, when the far-infrared radiation sheet is made of carbon fiber mixed paper, sufficient far-infrared radiation can be efficiently radiated and the heating efficiency is high.

FIG. 2 is a view of the ceiling heating unit of FIG. 1 viewed from below.

In FIG. 1, a room 1 is surrounded by a ceiling 2, a floor 3 and four walls 4. As shown in FIG. 2, four panel-shaped ceiling heating units (hereinafter abbreviated as heating units) 5 are attached to the central portion of the lower surface of the ceiling 2 so as to surround a square area. A lighting fixture (not shown) is usually attached to this square area. The radiation surface of each heating unit 5 is a wall 4
Is attached to the ceiling 2 with a predetermined attachment so as to face the direction.

Each heating unit 5 is connected to a commercial power source via a temperature controller 6 mounted on the wall 4. The user can set the on / off, temperature and energization time of each heating unit 5 by operating the switch of the temperature controller 6 directly or by using the remote controller.

FIG. 3 is a sectional view showing the structure of the heating unit 5. As shown in FIG. 3, the heating unit 5 is formed by laminating the heat insulating material 20 on the back surface of the far-infrared radiation sheet 10, and the frames 30 are fitted to the four sides thereof. The far-infrared radiation sheet 10 is made of carbon fiber mixed paper described later,
The heat insulating material 20 is made of, for example, a foaming resin. Also, the frame 30
Is made of metal such as aluminum, synthetic resin, or wood.

FIG. 4 shows a schematic plan view of the far-infrared radiation sheet 10, and FIG. 5 shows a sectional view of the end portion of the far-infrared radiation sheet 10. The far-infrared radiation sheet 10 includes a carbon fiber mixed paper 100 and resin layers 101 and 102 laminated on both sides of the carbon fiber mixed paper 100. The resin layers 101 and 102 are formed of, for example, glass fiber reinforced epoxy resin (hereinafter referred to as glass epoxy resin) or FRP (fiber reinforced plastic). The far-infrared radiation sheet 10 is manufactured as follows.

Water is added to bast fibers such as Kozo, Mitsumata, and Gampi, which are raw materials of Japanese paper, to make a pulp liquid, and carbon fibers cut to a predetermined size, for example, about 5 mm are mixed therein and dispersed. Let The pulp solution is flowed on a papermaking net to form a wet sheet. The wet sheet is mechanically squeezed using a squeezing roll, dried, and then cut into predetermined dimensions. Thus, the carbon fiber mixed paper 1 having a thickness of about 0.1 mm
00 is formed.

Then, on the surface of the carbon fiber mixed paper 100, a silver paste 104 is printed in a strip shape having a width of about 1 cm along two opposite sides, and a copper coated with a conductive adhesive is applied on the silver paste 104. The foil tape 103 is attached. In this way, a pair of electrodes is formed at the edge of the carbon fiber mixed paper 100.

Further, for example, the carbon fiber mixed paper 100 is sandwiched by a resin in a dry state and hot pressed to heat cure the resin. At this time, as shown in FIG. 5, a hole for attaching a conductive wire is formed in the resin in the end region of each copper foil tape 103. In this way, the resin layers 101 and 102 are laminated on both sides of the carbon fiber mixed paper 100. Finally, the conductor wire 105 is connected to one end of each copper foil tape 103 by soldering or the like. In this way, the far infrared radiation sheet 10 having a thickness of about 0.5 mm is manufactured. The far-infrared radiation sheet 10 is lightweight and flexible.

Since the resin layers 101 and 102 are provided to impart insulation to the surface of the carbon fiber mixed paper 100 and to mold the carbon fiber mixed paper 100 into a sheet shape, the resin layers 101 and 102 are provided. As the material of 102, various materials having such a function can be used. Further, instead of hot pressing the resin layers 101 and 102 on the carbon fiber mixed paper 100, an insulating resin may be applied or sprayed on the surface of the carbon fiber mixed paper 100. A fabric sheet may be attached to one surface or both surfaces of the far-infrared radiation sheet 10.

Far-infrared radiation sheet 1 via conducting wire 105
When a voltage is applied to the pair of 0 copper foil tapes 103, an electric current flows through the carbon fibers dispersed in the carbon fiber mixed paper 100, and the carbon fibers generate heat to generate the carbon fiber mixed paper 100.
Far-infrared rays are radiated forward from both sides.

The heat generation amount and set temperature of the far infrared radiation sheet 10 are adjusted by the amount of carbon fibers mixed in the carbon fiber mixed paper 100 and the current control by the temperature controller 6 or the applied voltage. In this embodiment, the heat generation amount of the far infrared radiation sheet 10 is appropriately adjusted within the range of 0 to 300W.

Far-infrared rays emitted from the far-infrared ray radiating sheet 10 made of the carbon fiber mixed paper 100 can directly give heat energy to the inside of the human body with little intervening air. Therefore, by using this far-infrared radiation sheet 10, the human body part can be warmed quickly and efficiently.
