Also, the present invention relates to a foil or plate- shaped waveguide for far infrared guidance, which is made of vacuum-deposited metal fiber or fiber with a thin metal plate being attached to one side or both sides thereof.
- the present invention has been made in view of the above problems, and it is an object of the present invention to provide a drying apparatus using far infrared and a drying unit for creating a large-scale drying area for the painting job both indoors and outdoors, irrespective of cold and/or humid weather, by radiating electromagnetic waves of a far infrared region over a long distance.
- a far infrared drying apparatus comprising: at least one far infrared drying unit, which is heated by an electric heating element and converts heat energy into far infrared rays, namely, electromagnetic wave energy; a support frame for supporting the at least one far infrared drying unit; a moving device for moving the support frame; and a waveguide for guiding the far infrared rays over a long distance onto an object to be dried.
- the drying unit features a higher heating efficiency than a conventional far infrared heater, thereby considerably improving the heat efficiency and the far infrared radiation efficiency.
- the frame moving device can move the frame using a rail and a driving motor, while being supported by a building pillar for instance, or along the rail on the ground below.
- the waveguide according to the present invention is a device for guiding far infrared rays generated from the far infrared drying unit over a long distance.
- the waveguide is made of a large-scale of metal vacuum-deposited fiber or a large-scale fiber with a thin metal plate being attached to one side or both sides thereof. As such, the waveguide can be applied to a large drying area. And, if necessary, the waveguide can be wound also.
- a conventional waveguide was a small-sized waveguide made of metallic materials and used exclusively for the transmission of electromagnetic waves.
- any kind of fiber can be used for metal vacuum deposition.
- the fiber include natural fibers such as cotton and hemp, synthetic fibers such as rayon, acetate, polyamide (nylon), polyester, acryl, polyurethane, carbon fiber, glass fiber, and Teflon, and finished/processed fibers such as a non-woven fiber.

- synthetic fibers such as rayon, acetate, polyamide (nylon), polyester, acryl, polyurethane, carbon fiber, glass fiber, and Teflon
- finished/processed fibers such as a non-woven fiber.
- any inflammable fibers go through the flame retardant treatment.
- the metal for use in metal vacuum deposition should have high far infrared re- flectivity.
- Preferable examples of such metal include silver and aluminum.
- any well-known metal vacuum deposition method in the art can be used.
- the fiber with a thin metal plate being attached to one side or both sides thereof is prepared by adhering a thin metal plate onto one side or both sides of the fiber through a heat resistant adhesive.

- the thin metal plate is 1 - 100D in thickness.
- the radiation distance of the far infrared rays (i.e., the electromagnetic wave energy) converted at the far infrared drying unit can be extended from 70cm conventional up to 50m or more. Also, by keeping the surrounding temperature of the far infrared converter at 200 - 500oC, the energy efficiency can be improved markedly. In this manner, the heat loss of the far infrared converter, which is the main cause of reduction in the generation rate of far infrared rays, due to the convection of heated air in the drying space, i.e., outdoors, conveyor tunnel or box- typed drying space, can be reduced very effectively.
- the drying apparatus has a movable structure, the drying space can be used more efficiently.

Therefore, to protect the far infrared drying units 10 from the dust, it is necessary to move the drying apparatus away in the horizontal direction, or move the drying units away to a predetermined place for conveniently drying a certain area of the drying apparatus.
- the moving device 14 is installed to meet these needs.
- the moving device 14 includes a motor and wheels 20 that move on a rail 18 being supported by a separate structure 16 such as a pillar or the wall of a building.
- the moving device 14 is installed at sides, lower portion or upper portion of the support frame.
- the waveguide 22 is suspended from the support frame 12 in such a manner that it can radiate far infrared rays very effectively onto the object to be dried. That is to say, the waveguide 22 makes sure that the far infrared rays having been converted at each of the drying unit 10 do not escape and disperse to the outside but are guided to the object to be dried inside the drying apparatus.
- the waveguide 22 is installed on the front and rear surfaces of the drying apparatus, along each side, or at least one side of the drying apparatus.
- the waveguide 22 is made of far infrared reflecting materials. For instance, an aluminum foil is attached to a textile material or a non- woven fabric in form of a curtain. In this manner, it becomes easier to adjust the height of the waveguide 22.
- an adjusting device 24 for adjusting the height of the waveguide 22 is provided, so that the far infrared radiation can be adjusted by the size or height of the object to be dried.
- An example of the adjusting device 24 is a roller or a motor.

- FIG. 3 is a schematic view of the far infrared drying unit 10 for use in the far infrared drying apparatus of Fig. 1
- Fig. 4 is a partial cross-sectional view of a reflective mirror for use in the drying unit and a waveguide extended perpendicularly therefrom.
- Each of the far infrared drying unit 10 includes at least one far infrared converter 30 for converting heat energy of an electric heating element into electromagnetic wave energy.
- the far infrared rays from the far infrared converter 30 are guided by (to be more specific, reflected from) a reflective mirror 32 on the upper portion of the drying unit 10 towards an object to be dried.
- the reflective mirror 32 is preferably in a concave shape. That is, the curved portion of the reflective mirror 32 is extended downwards or in the perpendicular direction, and forms a waveguide 32a that creates a layer of heated air for getting hot air.
- the waveguide 32a extended downwards or in the perpendicular direction from the reflective mirror 32 prevents heated air from being convected and far infrared rays from scattering to the outside and guides them onto the object to be dried.
- the waveguide 32a is installed in such a manner that it encompasses the far infrared converter 30.
- the far infrared converter 30 is not easily cooled down by the convection of air having a lower temperature than the surrounding temperature of the converter 30, and the heat efficiency is increased markedly.
- an insulating layer 32b is formed on the outside of the reflective mirror 32 and the waveguide 32a.
- Fig. 5 is a schematic view of the far infrared drying unit for use in the far infrared drying apparatus according to the embodiment (refer to Fig. 2) of the present invention.
- the far infrared drying unit 40 includes at least one far infrared converter 42 inside, similar to the one shown in Fig. 3.
- the far infrared rays from the far infrared converter 42 are guided by a reflective mirror 44 on the upper portion of the drying unit 40 towards an object to be dried.
- the reflective mirror 44 is preferably in a concave shape.
- the curved portion of the reflective mirror 44 is extended downwards or in the perpendicular direction, and forms a waveguide 44a that creates a layer of heated air for getting hot air.
- the waveguide 44a extended downwards or in the perpendicular direction from the reflective mirror 44 prevents far infrared rays from dispersing to the outside and guides them onto the object to be dried.
- the waveguide 44a is installed in such a manner that it encompasses the far infrared converter 42. As a result, the heat of the far infrared converter 42 is not easily lost by the air convection, and the heat efficiency is increased markedly.
- Fig. 6 is a cross-sectional view of a waveguide for use in a drying unit, in which the waveguide is capable of guiding far infrared rays over a long distance and simultaneously, onto a painted portion only.
- Fig. 6 is a conceptual cross- sectional view illustrating a waveguide made of thin metal plates deposited over both sides of a cloth.
- the double-side cloth is prepared by applying a heat resistant adhesive 3 to a thin metal plate 2 selected from metals having a high electromagnetic reflectivity such as silver, copper, aluminum and SUS, and to a fiber 4 selected from nonflammable fibers such as carbon fiber and glass fiber; and depositing the thin metal plate 4 on both side surfaces of the fiber 4.
- the drying apparatus By encompassing the drying apparatus with the prepared waveguide, it becomes possible to increase the far infrared radiation distance considerably. As such, the drying apparatus can be advantageously used for a large-scale drying area, and even a large-scale object can be dried within a short period of time.
