Description

The present invention relates to a radiant heating device and a radiant heating system.

Conventionally, radiant heating devices have been provided that can warm a room and the bodies of people in the room using far infrared rays emitted from a radiant heater.

Figure 2 shows a conventional radiant heating device.

In the figure, 11 is a radiant heating device attached to the wall of a room, Hz is a housing, 13 is a block-shaped radiant heater contained within the housing Hz, and 14 is a power supply device connected to the radiant heater 13 and supplies power to the radiant heater 13.

The radiant heater 13 comprises a radiator made of a heat-resistant material such as metal, ceramics, or heat-resistant resin, and a heating wire connected to the power supply 14. When the radiator is heated by passing electricity through the heating wire, far infrared rays are emitted from the radiator. This warms the bodies of people in the room, as well as the walls, floor, ceiling, etc. in the room, and the heat from the walls, floor, ceiling, etc. is transferred to the air, making the room warmer (see, for example, Patent Document 1).

JP 2020-53285 A

However, when the conventional radiant heating device 11 is installed on the floor of a room, the floor area of the room is reduced accordingly, and when installed high up on a wall, it protrudes from the wall, creating a feeling of oppression for people in the room.

Therefore, radiant heating devices have been provided that have a plate-shaped radiator, i.e., a radiant plate, that is installed along the wall of a room.

Figure 3 shows another conventional radiant heating device.

In the figure, Ws is the wall of the room, and 21 is a radiant heating device installed on wall Ws.

The radiant heating device 21 has a belt-like shape and is equipped with multiple radiant plates 23 and heating wires arranged in parallel within a frame 22 that forms the four sides. When the heating wires are energized, far infrared rays are emitted from the radiant plates 23. This warms the bodies of people in the room, as well as the walls, floor, ceiling, etc. in the room, and the heat from the walls, floor, ceiling, etc. is transferred to the air, making the room warmer.

However, the other conventional radiant heating device 21 occupies the room's walls Ws with multiple radiant plates 23, which can make people in the room feel uncomfortable.

The present invention aims to solve the problems of the conventional radiant heating devices and provide a radiant heating device and radiant heating system that does not cause people in the room to feel oppressed or uncomfortable.

To this end, the radiant heating device of the present invention comprises a frame body, a heat radiator that is surrounded by the frame body and is supplied with power to radiate far-infrared rays, and an image body that is disposed in front of the heat radiator and is made up of a sheet material that transmits far-infrared rays and an image formed on the sheet material.

In another radiant heating device of the present invention, the heat radiator is a planar heater having a laminated structure formed by sandwiching a heater main body formed by evaporating carbon onto the surface of a thin substrate between first and second films, heating and pressurizing the heater main body.

In the radiant heating system of the present invention, the radiant heating device is installed facing a wall formed by incorporating carbon into a high far-infrared emissivity material.

According to the present invention, the radiant heating device comprises a frame body, a heat radiator that is surrounded by the frame body and is supplied with power to radiate far-infrared rays, and an image body that is disposed in front of the heat radiator and is made up of a sheet material that transmits far-infrared rays and an image formed on the sheet material.

In this case, the far infrared rays emitted from the thermal radiator warm the bodies of the people in the room, as well as the walls, floor, ceiling, etc. in the room, and the heat from the walls, floor, ceiling, etc. is transferred to the air, making the room warmer.

In addition, since the radiant heating device can be installed on the wall, not only is the floor space not reduced, but the radiant heating device can also be made thin, so people in the room do not feel oppressive.

And because the image is formed on the image body of the radiant heating device, people in the room do not feel uncomfortable, making the room a comfortable space.

In addition, the image can be replaced with one that displays a different image as needed, making the room an even more comfortable space.

Also, according to the present invention, in another radiant heating device, the heat radiator is a planar heater having a laminated structure formed by sandwiching a heater main body formed by evaporating carbon onto the surface of a thin substrate between first and second films, heating and pressurizing the heater main body.

And according to the present invention, in the radiant heating system, the radiant heating device is installed facing a wall formed by incorporating carbon into a high far-infrared emissivity material.

In this case, far-infrared rays with the same wavelength as those emitted by the thermal radiator are absorbed and radiated by the wall, and the far-infrared rays resonate with each other, causing thermal energy to move instantly within the room. As a result, the bodies of people in the room are rapidly heated.

The following describes in detail an embodiment of the present invention with reference to the drawings. In this case, a radiant heating system will be described.

Figure 1 shows a radiant heating system in the first embodiment of the present invention, Figure 4 shows the installation state of the forehead in the first embodiment of the present invention, and Figure 5 is an exploded perspective view of the forehead in the first embodiment of the present invention.

In the figure, R1 is a room, Wsi (i = 1, 2, ...) is a wall as the first wall, Bw is a floor as the second wall, and Tw is a ceiling as the third wall.

In this embodiment, a predetermined portion of the wall Wsi and ceiling Tw is formed by adding a predetermined amount of carbon, in this embodiment 1% to 10% by weight, to a high far-infrared emissivity material.

The high far-infrared emissivity material is, intrinsically, a material with high far-infrared emissivity, such as interior wall coating materials, for example, diatomaceous earth, lime plaster, (traditional Japanese) clay walls, shirasu balloon soil, and zeolite soil.

In this embodiment, the plaster wall materials are applied directly to the framework of the walls Wsi and ceiling Tw using a trowel or the like, but they can also be applied to a sheet material such as wallpaper using a brush or the like, and then the sheet material can be attached to the framework of the walls Wsi and ceiling Tw, or paint containing the plaster wall materials as raw materials can be created and applied to the framework of the walls Wsi and ceiling Tw.

When using diatomaceous earth as a wall coating material, since diatomaceous earth is a white material, if the amount of carbon added is increased, the walls Wsi and ceiling Tw will take on a black color, so it is preferable to use a carbon content of 2% to 3%.

In the figure, 31 is a frame as a radiant heating device that is installed so as to be freely attached and detached by hanging it on a specific wall among the walls Wsi, in this embodiment, on wall Ws1. In this case, the frame 31 is installed in a position where it can radiate far infrared rays to other walls Ws2, Ws3, the floor Bw, the ceiling Tw, etc. among the walls Wsi.

As shown in FIG. 5, the frame 31 is formed by stacking a frame 33 as a frame body, a mat 34, an image body Mg, a planar heater Ht as a heat radiator, and a back plate 36. The mat 34, image body Mg, and planar heater Ht are surrounded by the frame 33 and sandwiched between the frame 33 and the back plate 36.

The mat 34 is formed with a window 38 having a predetermined shape corresponding to the size of the image body Mg, in this embodiment, a rectangular shape, and the four sides of the image body Mg are covered by the window 38.

The image body Mg is composed of a sheet material Sh, such as paper, film, or nonwoven fabric, which transmits far-infrared rays, and an image Pr, such as a painting or photograph, formed in a predetermined area Ar on the surface of the sheet material Sh facing the mat 34, i.e., the front surface. The image body Mg can be removed from the frame 31 and replaced with one having a different image Pr formed thereon, as necessary.

The planar heater Ht is disposed behind the image body Mg and is supplied with power to emit far infrared rays, as described below.

If necessary, a cover made of a material that transmits far infrared rays, such as glass, can be placed in front of the mat 34.

Next, we will explain the planar heater Ht.

Figure 6 is a perspective view showing the laminate structure of a planar heater in the first embodiment of the present invention.

In the figure, Ht is a planar heater, 41 is a heater main body that serves as the heat source for the planar heater Ht, 43 is a first film that covers the surface of the heater main body 41 facing the mat 34 (Figure 5), i.e., the front side, and 44 is a second film that covers the surface of the planar heater 41 facing the back plate 36, i.e., the back side. The first and second films 43 and 44 are made of resin films such as polyester, polypropylene, ethylene-vinyl acetate copolymer, olefin-based elastomer, and urethane.

The planar heater Ht has a laminated structure formed by sandwiching the heater body 41 between the first and second films 43 and 44, and applying heat and pressure to them.

The heater body 41 has a serpentine structure and is formed by connecting the ends of multiple strip-shaped parts Bj (j = 1, 2, ...) with conductive connectors Ck (k = 1, 2, ...), with electrodes tm1 and tm2 connected to both ends, and connected to a commercial power source via the electrodes tm1 and tm2.

Each belt-shaped portion Bj is formed by evaporating carbon onto a thin substrate such as Japanese paper or a film with a thickness of about 2 mm. In this embodiment, the surface of the Japanese paper facing the mat 34, that is, the surface to be vapor-deposited, is the surface to be vapor-deposited. The carbon vapor-deposited onto the vapor-deposited surface of the Japanese paper is made of the same components as the carbon contained in the diatomaceous earth and has the same molecular vibration frequency.

When power is supplied to the planar heater Ht and the planar heater Ht is heated to a predetermined temperature, in this embodiment, 40°C to 60°C, the carbon deposited on the deposition surface of the Japanese paper forms a black body, and far-infrared rays with high radiance and high radiation intensity are emitted from the planar heater Ht. Note that since the radiation intensity of the far-infrared rays varies depending on the amount of carbon deposited, it is preferable to deposit 100% of the carbon onto the Japanese paper.

Furthermore, since the far-infrared rays emitted from the planar heater Ht pass through the image body Mg and are emitted into the room R1 (Figure 1), the thickness of the sheet material Sh is set to 2 μm or less so that the far-infrared rays can sufficiently pass through the image body Mg.

When far infrared rays emitted from the surface heater Ht are irradiated on a person, the moisture on the surface of the person's skin is vibrated, and the person feels warm, so the forehead 31 can be used for radiant heating.

Next, we will explain the behavior of far infrared rays radiated into room R1.

Figure 7 is a diagram to explain the behavior of far-infrared rays radiated from the forehead into the room in the first embodiment of the present invention.

In the diagram, R1 is the room, Wsi is the wall, Bw is the floor, Tw is the ceiling, and 31 is the frame.

When far-infrared rays are emitted from the planar heater Ht (Figure 5) on the forehead 31 as shown by the dashed line, the far-infrared rays vibrate the moisture on the surface of the skin of the people in the room, warming their bodies and also warming the walls Wsi, floor Bw, ceiling Tw, etc. in the room R1, and the heat from the walls Wsi, floor Bw, ceiling Tw, etc. is transferred to the air, making the room warmer.

Furthermore, when far-infrared rays are radiated from the planar heater Ht toward the walls Wsi and ceiling Tw in the room R1, the far-infrared rays are absorbed by the walls Wsi and ceiling Tw and far-infrared rays of the same wavelength are radiated, so that the bodies of people in the room R1 are warmed further, and the walls Wsi, floor Bw, ceiling Tw, etc. in the room are warmed further, and the heat of the walls Wsi, floor Bw, ceiling Tw, etc. is transferred to the air, making the room even warmer.

In addition, as in this embodiment, when the carbon contained in the diatomaceous earth in the walls Wsi and ceiling Tw and the carbon evaporated onto the Japanese paper in the planar heater Ht are of the same composition, the two carbons have the same molecular vibration frequency, so that the walls Wsi and ceiling Tw radiate far infrared rays of the same wavelength as the far infrared rays radiated from the planar heater Ht, and the far infrared rays resonate and resonate with each other.

As a result, thermal energy moves instantly within room R1, causing the bodies of people in room R1 to heat up quickly.

The dimensions of the frame 31 can be set arbitrarily, such as 10 cm x 10 cm, 100 cm x 100 cm, etc., depending on the size of the room R1.

In addition, multiple frames can be installed depending on the size of room R1.

In this embodiment, when far infrared rays emitted from the planar heater Ht are irradiated onto a person in the room R1, the moisture on the surface of the person's skin is vibrated, and the person feels warmth, so the planar heater Ht can be used for radiant heating.

In addition, since the frame 31 can be hung on the wall Wsi, not only is the floor area not reduced, but the frame 31 can be made thin, so it does not create a feeling of oppression for people in the room R1.

Since the image Pr is formed on the image body Mg, people in the room R1 do not feel uncomfortable, and the room R1 can be made into a comfortable space.

Furthermore, the image body Mg can be replaced with one on which a different image Pr is formed as needed, making the room R1 an even more comfortable space.

In addition, in this embodiment, far-infrared rays of the same wavelength as those emitted from the planar heater Ht are absorbed and emitted by the walls Wsi and ceiling Tw, and the far-infrared rays resonate and vibrate with each other, so that thermal energy moves instantly within the room R1. As a result, people can feel even warmer.

Next, a second embodiment of the present invention will be described. Note that the same reference numerals are used for components having the same structure as the first embodiment, and the effects of the invention resulting from having the same structure are the same as those of the first embodiment.

Figure 8 is an exploded perspective view of a forehead in the second embodiment of the present invention, and Figure 9 is a perspective view showing the layered structure of a planar heater in the second embodiment of the present invention.

In the figure, 31 is a frame serving as a radiant heating device, and the frame 31 is formed by stacking from the front to the back a frame 33 serving as a frame body, a mat 34, a surface heater Htg serving as a heat radiator, and a back plate 36.

The planar heater Htg has a laminated structure formed by sandwiching the heater body 41, which serves as the heat source of the planar heater Htg, between the first and second films 43g and 44, and applying heat and pressure to the heater body 41.

Then, an image Pr (Figure 4), such as a painting or a photograph, is formed in the area Ar on the mat 34 side of the first film 43g.

In this embodiment, there is no need to place the image body Mg in front of the planar heater Htg, so the cost of the frame 31 can be reduced.

In addition, since the far-infrared rays are radiated directly into the room R1 without passing through the image body Mg, the radiation intensity of the far-infrared rays can be increased.

The present invention is not limited to the above-described embodiments, and various modifications are possible based on the spirit of the present invention, and are not excluded from the scope of the present invention.
