- Patent Document 1 As an infrared heater, a rod-shaped heating element made of carbon or silicon carbide that emits infrared rays when heated, and a light-transmitting property in which the heating element is hermetically accommodated What is provided with a cylindrical protective tube made of alumina ceramics is known.
- This protective tube has a total transmittance of electromagnetic waves having a wavelength of 0.4 to 6 ⁇ m of 80% or more.
- the present invention has been made to solve such a problem, and has as its main object to provide a plurality of infrared heating environments having different spectra with a single infrared heater.
- the wavelength control heater of the present invention employs the following means in order to achieve the above-mentioned main purpose.
- the wavelength control heater of the present invention is A heating element that emits infrared when heated, When the temperature is lower than a predetermined threshold, the infrared transmittance is high, and when the temperature is higher than the threshold, the filter surface has a property of decreasing the infrared transmittance; Temperature adjusting means for adjusting the temperature of the filter surface; Setting means for selecting and setting the type of infrared rays emitted from the wavelength control heater to the outside from options including the first infrared ray and the second infrared ray; When the first infrared ray is set, the temperature adjusting means is controlled so that the temperature of the filter surface is lower than the threshold value. When the second infrared ray is set, Control means for controlling the temperature adjusting means so that the temperature of the filter surface is higher than the threshold and the filter surface becomes the second infrared radiation source; It is equipped with.
- the heating element itself is kept at a relatively high temperature so that the radiation energy per unit area is large and infrared rays in a short wavelength region can be emitted.
- the temperature adjusting means is controlled so that the temperature of the filter surface is lower than the threshold value. Then, the infrared transmittance of the filter surface is increased. As a result, most of the infrared rays emitted from the heating element are transmitted to the outside through the filter surface, which becomes the main radiation source when the first infrared ray is set.
- the temperature adjusting means is controlled so that the temperature of the filter surface becomes higher than the threshold value. Then, the filter surface has a low infrared transmittance, and the infrared rays emitted from the heating element are not easily transmitted through the filter surface, and the process of repeatedly reflecting and absorbing radiation between the heating element and the filter surface is repeated. As a result, the temperature of the filter surface rises. As a result, the main radiation surface is converted from the heating element to the filter surface, and the infrared radiation emitted outward from the filter surface becomes the main radiation source to the outside when the second infrared radiation is set. .
- the temperature of the filter surface needs to be adjusted so as to finally have a temperature on the radiation spectrum in the wavelength range assumed for the second infrared ray.
- the first infrared ray has a spectrum peak in the near infrared region (eg, 0.7 to 3 ⁇ m), and the second infrared ray has a spectrum peak in the far infrared region (eg, 4 to 8 ⁇ m). Also good.
- the heating element temperature serving as the first infrared light source is 700 to 1500 ° C.

- the wavelength control heater of the present invention further includes an infrared transmission surface disposed on at least one of the inside and the outside of the filter surface, and a refrigerant flow path formed between the filter surface and the infrared transmission surface.
- the temperature adjusting means may adjust at least one of a flow rate and a temperature of the refrigerant flowing through the refrigerant flow path. Since the refrigerant flow path formed between the filter surface and the infrared transmission surface is in contact with the filter surface, the temperature of the filter surface can be adjusted by adjusting at least one of the flow rate and temperature of the refrigerant flowing through the refrigerant flow channel. Can be controlled relatively easily.
- the infrared transmission surface is disposed in two layers on the outside of the filter surface, and the coolant channel is also formed between the infrared transmission surfaces disposed in two layers on the outside of the filter surface. Also good. Since the refrigerant flow path between the infrared transmitting surfaces arranged in two layers on the outside of the filter surface is in contact with the outside air, the surface temperature of the wavelength control heater can be adjusted by adjusting the flow rate of the refrigerant flowing through the refrigerant flow path. Can be lowered. For example, when an object containing an organic solvent is dried, vapor of the organic solvent exists around the wavelength control heater, but the surface temperature of the wavelength control heater can be lowered, so that safety is improved. high.
- the infrared transmission surface is disposed in one layer inside the filter surface and two layers outside the filter surface, and the refrigerant flow path includes the filter surface and an infrared transmission surface arranged inside the filter surface.
- the control surface is formed between the filter surface and the infrared transmission surface disposed in the first layer outside the filter surface and between the infrared transmission surfaces disposed in two layers outside the filter surface.
- the means When the first infrared ray is set as the type of the infrared ray, the means includes a refrigerant passage between the filter surface and an infrared ray transmitting surface arranged inside the filter surface, the filter surface, The temperature adjusting means is controlled so that the refrigerant flows through the refrigerant passage between the infrared ray transmitting surface arranged on the first layer outside the filter surface, and the second infrared ray is set as the infrared ray type. If it is, the refrigerant in the refrigerant passage formed between the infrared transmission faces which are arranged two layers on the outside of the filter surface may control the temperature regulating means so as to flow. In this way, the temperature of the filter surface can be made relatively easily below the threshold, or the temperature of the filter surface can be made higher than the threshold and the filter surface can be an infrared radiation source.

And if near infrared rays were set up, the 1st and 2nd on-off valves 71 and 72 will be opened, and the 3rd on-off valve 73 will be closed (Step S120).

- the third flow rate adjustment valve 82 and the power supply source 50 are controlled (step S150).
- the temperature of the filter tube 18 becomes 68 ° C. or higher due to the heat of the filament 12, the infrared transmittance of vanadium oxide is lowered (about 10 to 20%), so that the infrared rays emitted from the filament 12 are not easily transmitted through the filter tube 18.

In this case, the third flow rate adjustment valve 83 maintains that state. If the temperature of the filter tube 18 cannot be kept at 300 ° C. ⁇ ⁇ ° C.
- the power supply source 50 is adjusted so that the power supplied to the filament 12 increases or decreases. As a result, the temperature of the filament 12 rises or falls, and as a result, the temperature of the filter tube 18 also rises and falls due to the influence.
- the temperature of the filter tube 18 is set to 300 ° C. ⁇ ⁇ ° C.
- the wavelength control heater 10 emits far infrared radiation having a spectrum indicated by a solid line in FIG. Since the temperature is as low as 300 ° C. ⁇ ⁇ ° C., the peak wavelength shifts to the long wavelength side as compared with the wavelength characteristic indicated by the dotted line. As is clear from FIG. 5, most of the emitted infrared light is in the far infrared region.
