本発明は紫外線照射器具、特にそのランプ冷却機・構の
改ｊＬに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultraviolet irradiation device, particularly to a modified lamp cooling mechanism.
従来、紫外線ランプを収容する凹面反射閾の最奥部に排
気孔を設けた紫外線照射器具が知られている。このもの
は冷却気流がランプ外面に沿って流れるとと題二よって
ランプ外面を冷却するようになっている。しかしながら
、従来のものはランプの排気側において気流がランプ外
側から剥離して渦巻きを生じ、このためランプの排気孔
側は冷却が悪くなシ、ランプ破損の原因となったり、あ
るいは冷却気流を強くすることによってランプの局部的
過冷却を生じたりする欠点があった。Conventionally, an ultraviolet irradiation device is known in which an exhaust hole is provided at the innermost part of a concave reflective threshold that accommodates an ultraviolet lamp. In this device, when a cooling air flow flows along the outer surface of the lamp, the outer surface of the lamp is cooled. However, with conventional lamps, the airflow separates from the outside of the lamp on the exhaust side of the lamp, creating a swirl, resulting in poor cooling on the exhaust side of the lamp, causing damage to the lamp, or forcing the cooling airflow too strongly. This has the drawback of causing local supercooling of the lamp.
この対策として、特公昭５５−１６２８１号公報に見ら
れるように′、紫外線ランプを排気孔に接近させた紫外
線照射器具が提案された。しかし彦からこの方法はラン
プが排気孔に近接すると、反射板が熱によって破損する
おそれがあり、さりとてランプを排気孔から離せば渦流
の防止が不充分で、ランプの冷却不均一を防止するζ二
は不充分である。As a countermeasure to this problem, an ultraviolet irradiation device was proposed in which an ultraviolet lamp was placed close to the exhaust hole, as seen in Japanese Patent Publication No. 16281/1981. However, with this method, if the lamp is placed close to the exhaust hole, the reflector may be damaged by the heat, and if the lamp is moved away from the exhaust hole, the prevention of eddy currents will be insufficient, and uneven cooling of the lamp will be prevented. 2 is insufficient.

ンプ外面の温度不均一をなくするものである。The present invention has been made in order to eliminate such drawbacks of the prior art, and includes a first reflecting section, 8, in which a concave reflecting plate is provided in the inner part.
The second reflective part and IJ provided on both sides of the first mouth part.
It consists of a stepped section connecting both sides of the reflecting section of I and each of the second reflecting section, and exhaust holes are provided in each of the stepped sections on both sides, thereby improving cooling with a small reflecting plate. This eliminates temperature non-uniformity on the outer surface of the lamp.

1) an ultraviolet lamp such as a high-pressure mercury vapor discharge lamp installed in the interior; (3) a concave reflector that covers the back of this lamp (2) and opens at the bottom of the lamp body (1); (4) this This is an exhaust hole provided in the reflection plate (3). Above reflector (3)
is the inner part (generally a first reflecting part (5) forming a concave surface, second reflecting parts (7) forming a concave surface provided on both sides of the opening (6), (7) and the first reflecting part It consists of step portions (8), (8) connecting between (1) and the reflecting portion (sword) of w12 on both sides (7), both step portions (8),
The exhaust holes (4), (4) are opened in <8>, respectively, and the first reflecting part (5) is further provided with a ventilation hole (9).
つぎに、本紫外線照射器具の作用を説明する。Next, the operation of this ultraviolet irradiation device will be explained.

さく、したがって冷却不良による過熱のおそれもない。The ultraviolet lamp (2) is lit, and both exhaust holes (4) i4
). Then, the outside air is sucked in through both the opening (6) and the ventilation hole (9), and the air is sucked in through both the exhaust holes (4) and (
4) is discharged from. At this time, since the stepped portions (8), (8) are close to the lamp (2) on both sides of the lamp (2), the distance between the lamp (2) and the exhaust holes (4), (4) is It is small and has good cooling, and since both sides of the lamp (2) are relatively low temperature, the effect of cooling inhibition due to eddies is small, and therefore there is no risk of overheating due to poor cooling.
