果のコントロールに極めて重要である。In such an irradiator, the inside of the irradiator body becomes extremely hot when the ultraviolet light source is turned on, so the inside is air-cooled using an exhaust device or the like. If a reflective aluminum casting is used, a large amount of heat rays will be reflected as well as ultraviolet silver, so
When the object to be irradiated is a material that is sensitive to heat, there is a melting process in which the object becomes softened and deformed. Therefore, in place of aluminum reflectors, heat ray transmitting and reflecting plates that allow heat rays to pass through and reflect only ultraviolet rays have come to be used. A typical example of dark reflection C is a multilayer interference film formed by depositing gold interference oxide on the surface of heat-resistant glass. Figure 3 shows the general external appearance of such a heat ray transmitting and reflecting mirror 1, and shows a state in which a tubular ultraviolet light source 2 is arranged inside. However, the bending reflector has the disadvantage that it is difficult to manufacture because a multilayer interference film is attached to the surface of a large glass body. In particular, it has been extremely difficult to appropriately control the entire reflection and emission of the film No. 4 of the multilayer interference film in order to uniformly irradiate the ultraviolet rays. In addition, since the entire reflective track remains and is large in size, it also has the disadvantage that stress due to thermal expansion cannot be absorbed. Furthermore, since there is no ventilation path that connects the inside and outside of the reflector, there is also the problem that even if air cooling is used, the cooling effect of the ultraviolet source is rather low. FIG. 4 shows a reflecting mirror groove structure proposed to improve the above-mentioned problems. This is a vertically long flat heat transmitting and reflecting plate 1.
a, 1b, 1c, etc. are arranged adjacently so that their cross sections are arcuate. In such a structure, it is sufficient to prepare a plurality of heat ray transmitting/reflecting plates 1a, 1b, 1c, . . . and combining the stiffness, so that the difficulty in manufacturing can be solved to some extent. Furthermore, since the adjacent gaps between the heat ray transmitting and reflecting plates form ventilation passages, the ultraviolet source cooling effect is greatly improved. However, in such a structure, the cross-sectional shape of the reflecting mirror cannot be made into an accurate circular arc shape such as a paraboloid or an ellipse, and therefore there is a difficulty in controlling ultraviolet rays. First, since the multilayer interference film is deposited on a very long glass plate, it is difficult to say that manufacturing problems have been completely resolved. Furthermore, since only the adjacent gaps between each heat ray transmitting and reflecting plate serve as ventilation channels,
The cooling effect of the part of the ultraviolet source that requires cooling is not sufficient,
Furthermore, it was impossible to control the cooling effect in the longitudinal direction of the ultraviolet source. For example, when a metal halide lamp is used as an ultraviolet mP, high luminous efficiency cannot be obtained unless the ends of the arc tube are kept warm and the entire center of the arc tube is appropriately cooled. This is extremely important for controlling the effects.

This ultraviolet irradiator has many features such as increasing the cooling effect inside and outside the reflector without causing damage, eliminating the stress caused by expansion, and being easy to manufacture, assemble, and maintain. This is what we provide.

る。The configuration of the reflecting mirror according to the present invention consists of both sides 4' of the ventilation plate 5 in which an appropriate number of ventilation holes 4a, 4b, and 4c are provided avoiding the edges.
alJ K, a plurality of heat ray transmitting and reflecting plates 6a to 6c made by bending relatively small glass plates into an arc shape along a parabola or a part of the structure and forming a multilayer interference film on the surface thereof. and 6f to 6j, all of which are connected to each other so that their adjacent gaps are tightly connected to the end of the ventilation plate 5 to form a gutter-like reflecting mirror 6. The number of heat transmitting and reflecting plates may be appropriately selected depending on the length of the σ ultraviolet source 9. Here, avoid the edge of the ventilation plate 5 and insert the ventilation hole 4.
a, 4b, and 4C, and heat ray transmitting and reflecting plates 6a to 6c.
and 6f to 6j (7) The reason why the adjacent gaps are also located at the end of the ventilation plate 5 is that the end of the ultraviolet light source, especially the metal halide lamp, is located in that part. By doing so, the ends of the metal halide lamp are kept warm and the center is appropriately cooled, resulting in high luminous efficiency. However, in this case, the heat ray transmitting reflector plates 6a located at both ends of the reflector 60
- The temperature of 6f and 6e-6j was extremely high, and a phenomenon in which their multilayer interference films peeled off was observed. Therefore, the present invention provides end plates 7a and 7 that are in contact with both ends of the reflecting mirror 6 in the longitudinal direction.
Among b, the heat ray transmitting and reflecting plates 6a, 6f and 6e, 6
An appropriate number of through holes 8a to 8d are provided at locations close to the outer surface of the housing 1 to communicate with the passageway between the outer casing 1 and the interior 3. As a result, only the temperature at the end of the reflecting mirror can be appropriately reduced. In addition, each of the heat ray transmitting and reflecting plates 6a to 6e and 6f
The adjacent gap formed between ~6j may be arbitrary, but if it is too large, it will affect the reflection efficiency of ultraviolet rays, and if it is too small, it will affect the cooling effect of the reflecting mirror. According to experimental examples, a certain effect can be obtained even if it is less than 1fi, but if it is completely blocked, the wall surface of the reflecting mirror will be affected. Another major advantage of the present invention is that the luminous efficiency of the ultraviolet light source can be increased.

られる。In addition, in a configuration in which the reflecting mirror is divided in a direction perpendicular to the longitudinal direction as in the present invention, each heat ray transmission reflection & 6
The production of a to 6e and 6f to 6j is extremely simple,
It is easy to handle, and it also has the advantage that even if a part of the heat ray transmissive reflector plate becomes corroded, it is not necessary to replace the entire reflector. However, in addition to kneading, it also has the following advantages: First, since the size of one unit of the heat ray transmitting reflection plate is relatively small, it is relatively easy to control the thickness of the multilayer interference film in the curved direction of each heat ray transmission reflection plate.
It can be done. For example, if the film thickness of each of the heat ray transmitting and reflecting plates 63 to 6e and 6f to 6j (111 near the ventilation plate 5 in Fig. 1) is set to the maximum thickness, it is possible to gradually obstruct the film toward the outside. It is. By doing this, the reflector ρ Fu2? The ultraviolet reflectance in the direction perpendicular to the hand direction can be changed, and the overall VCC uniform thermal irradiation intensity can be achieved.

ができる。According to the present invention, the reflectance of ultraviolet rays in the longitudinal direction of the reflecting mirror can also be easily controlled. In other words, as shown in FIGS. 5 and 6, the thickness of the multilayer 11"p film of each of the heat ray transmitting and reflecting plates 6a to 6e and 6f to 6j is set at the center in the longitudinal direction of the bell. In the heat ray transmitting/reflecting plates 6c and 6b, it is possible to gradually increase the thickness as the distance between $<L and the outer side of the film increases. How large is the central part?By using such a reflector configuration, the intensity of ultraviolet rays in the direction of the reflector can be made uniform.On the contrary, the intensity of ultraviolet rays in the longitudinal direction of the reflector itself can be made uniform. If you want to make the reflectance uniform, you can absorb the overall variation by replacing a part of each heat ray transmitting reflective plate. It is possible to control the ideal irradiation intensity for the selected substrate.Next, with the reflector configuration of the present invention, each of the heat ray transmitting and reflecting plates 68 to 6e, 6f to The length and width of 6j can be changed.

The effect of cooling the central part of the ultraviolet rays housed inside through a small gap and keeping both ends warm is further enhanced.Finally, the air-cooled young fruit inside the irradiator in the present invention will be explained.

When 0 is driven, the air outlet of the outer casing 1 causes the air to be sucked in through the through holes 8a, 8b- and 8C, 8d of the end plates 7a and 7b, as shown by the arrows. Inner 3 VC enters the outer side of the reflector 6 and goes to the exhaust hole 2
On the other hand, the air sucked in from the opening of the reflector 6 passes around Shiyu 1, 9, and passes through the ventilation holes 4a, 4b, 4C of the ventilation plate 5 and each heat transmission reflection. Zabuta 6a~

Additionally, this ventilation path is also indicated by arrows in FIGS. 5 and 6. In this way, the air cooling effect inside the irradiator can be maintained at 1 dl.
