Description

本発明は、電磁波（特に、波長が１００ｎｍから４８０ｎｍまでの範囲内にある紫外線及び可視光線）を放射して処理対象物を殺菌、加熱、反応等させるための電磁波照射装置に関し、特に、処理対象物が収納されるケーシングから電磁波放射部の一部が露出された電磁波発生源の出力を電磁波検出センサで検出するようにした電磁波照射装置に関するものである。 The present invention relates to an electromagnetic wave irradiation apparatus for sterilizing, heating, reacting, etc., an object to be processed by radiating electromagnetic waves (particularly, ultraviolet rays and visible rays having a wavelength in the range of 100 nm to 480 nm). The present invention relates to an electromagnetic wave irradiation apparatus in which an output of an electromagnetic wave generation source in which a part of an electromagnetic wave radiation part is exposed from a casing in which an object is stored is detected by an electromagnetic wave detection sensor.

しかしながら、このような従来の電磁波照射装置においては、第１従来例の場合には、ケーシングである紫外線照射タンクに複数のＵＶセンサが取り付けられており、そのＵＶセンサの受光部が処理対象物に直接接触する構造となっていた。そのため、ＵＶセンサの受光部が処理対象物によって影響を受けることがあり、例えば、処理対象物が受光部に付着することによってセンサの感度が低下し、紫外線ランプの正確な出力を測定することができないという課題があった。 However, in such a conventional electromagnetic wave irradiation apparatus, in the case of the first conventional example, a plurality of UV sensors are attached to an ultraviolet irradiation tank which is a casing, and the light receiving part of the UV sensor is a processing object. The structure was in direct contact. For this reason, the light receiving part of the UV sensor may be affected by the object to be processed. For example, when the object to be processed adheres to the light receiving part, the sensitivity of the sensor decreases, and the accurate output of the ultraviolet lamp can be measured. There was a problem that it was not possible.

また、第２従来例の場合には、紫外線光源の一部がケーシングである外槽の外に露出されており、その露出部にはキャップが装着されていて、そのキャップに貫通孔を設け、その貫通孔にＵＶセンサを嵌合固定する構造となっていた。そのため、ＵＶセンサの受光部が処理対象物によって汚染されることが無いことから、紫外線光源から放射されている電磁波の測定には適しているが、ＵＶセンサが貫通孔に嵌め込まれているため、紫外線光源から発生する熱が貫通孔内にこもってしまい、ＵＶセンサの温度が許容範囲以上に上昇してしまう。その結果、ＵＶセンサの加熱によって出力が不安定になり、紫外線光源から放射される電磁波の出力を正確に測定することができないという課題があった。 Further, in the case of the second conventional example, a part of the ultraviolet light source is exposed outside the outer tub which is a casing, a cap is attached to the exposed portion, and a through hole is provided in the cap. The UV sensor is fitted and fixed in the through hole. Therefore, since the light receiving part of the UV sensor is not contaminated by the object to be processed, it is suitable for the measurement of electromagnetic waves radiated from the ultraviolet light source, but the UV sensor is fitted in the through hole. The heat generated from the ultraviolet light source is trapped in the through hole, and the temperature of the UV sensor rises above the allowable range. As a result, output by the heating of the UV sensor becomes unstable, there is a problem that it is impossible to accurately measure the output of the electromagnetic wave emitted from the ultraviolet light source.

解決しようとする問題点は、ケーシングにＵＶセンサを取り付けて紫外線光源の出力を検出すると、ＵＶセンサの受光面が処理対象物の影響を受けて正確な値を検出することができないという点にある。また、ケーシング外にＵＶセンサを取り付けるとしても、キャップの貫通孔のような場所にＵＶセンサを設置すると、紫外線光源から放射される熱によってＵＶセンサの温度が高くなり、ＵＶセンサの出力が不安定になって同じく正確な値を検出することができない点にある。 The problem to be solved is that when the UV sensor is attached to the casing and the output of the ultraviolet light source is detected, the light receiving surface of the UV sensor is affected by the object to be processed and an accurate value cannot be detected. . Even if the UV sensor is installed outside the casing, if the UV sensor is installed in a place such as a through-hole in the cap, the temperature of the UV sensor increases due to the heat radiated from the ultraviolet light source, and the output of the UV sensor is unstable. In the same way, an accurate value cannot be detected.

Therefore, since the light receiving part of the electromagnetic wave detection sensor is not affected by the processing object, it is possible to prevent a decrease in sensor sensitivity due to the processing object adhering to the light receiving part.

電磁波検出センサの受光部が処理対象物の影響を受けることがないと共に、電磁波検出センサが電磁波発生源から受ける熱影響を少なくすることができ、電磁波発生源から放射される電磁波の出力を正確に検出することができる電磁波照射装置を、簡単な構造によって実現した。 The light receiving part of the electromagnetic wave detection sensor is not affected by the object to be processed, and the heat influence of the electromagnetic wave detection sensor from the electromagnetic wave generation source can be reduced, so that the output of the electromagnetic wave radiated from the electromagnetic wave generation source can be accurately performed. An electromagnetic wave irradiation device capable of detection was realized with a simple structure.

紫外線センサ３３は、紫外線の照射を受けて紫外線出力（入光パワー：ｍＷ／ｃｍ^２）に対応した信号（例えば、電圧値（Ｖ））を出力するもので、例えば、オムロン株式会社製のＵＶパワーモニタ（Ｆ３ＵＶ−Ａ３０／Ａ０３）等を用いることができる。 The ultraviolet sensor 33 outputs a signal (for example, a voltage value (V)) corresponding to an ultraviolet output (incident light power: mW / cm ² ) upon being irradiated with ultraviolet rays. A power monitor (F3UV-A30 / A03) or the like can be used.

これに対して、紫外線ランプ２０からの出力が直接測定され、更にきれいな状態の保護管２１を通過して測定され、これを出力の現在の基準値として用いることにより、実際の紫外線出力又はそれに近い値に基づいて常に紫外線殺菌装置１を制御することができる。そのために、例えばケーシング８の中途部分に紫外線センサを取り付けて別個に紫外線出力を測定し、その測定値と前記基準値とを比較することにより、ケーシング８に設けた内部を観察するための覗き窓の汚れか、処理対象物である液体自体の汚れか、紫外線ランプ２０自体の出力低下か、等を簡単に確認することができる。 On the other hand, the output from the ultraviolet lamp 20 is directly measured, measured through a clean protection tube 21, and used as the current reference value of the output, so that the actual ultraviolet output is at or close to it. The ultraviolet sterilizer 1 can always be controlled based on the value. For this purpose, for example, an ultraviolet sensor is attached to the middle part of the casing 8 to measure the ultraviolet output separately, and by comparing the measured value with the reference value, a viewing window for observing the inside of the casing 8 is observed. It is possible to easily check whether the liquid is the contamination of the liquid to be processed, the output of the ultraviolet lamp 20 itself is reduced, or the like.

即ち、本願発明では、ケーシング８の外部において保持具２２に固定される被覆部材３０を設け、この被覆部材３０に紫外線センサ３３を取り付けて、保護管２１を介して紫外線放射部から放射される紫外線の出力を測定するようにした。そのため、保護管２１のうち、処理対象物である水に接触することのない部分を介して紫外線の出力を測定することから、水によって汚れを生じた部位を測定するおそれがなく、実際に紫外線放射部から放射されている紫外線の出力に近い値（正確な値）を測定することができる。 That is, in the present invention, the covering member 30 fixed to the holder 22 is provided outside the casing 8, the ultraviolet sensor 33 is attached to the covering member 30, and the ultraviolet rays emitted from the ultraviolet radiation portion via the protective tube 21. The output of was to be measured. Therefore, since the output of the ultraviolet ray is measured through a portion of the protective tube 21 that does not come into contact with the water to be treated, there is no possibility of measuring a site that is contaminated by water, and the ultraviolet ray is actually measured. A value close to the output of the ultraviolet ray radiated from the radiating part (accurate value) can be measured.

Although not shown, the band member 81 is detachable and can be adjusted in length, and the ultraviolet sensor 33 can be fastened and fixed to the outer peripheral surface of the covering member 80 by its tightening force. A plurality of communication passages 40 are provided at appropriate intervals in the circumferential direction. Normally, one communication path 40 is sufficient, and therefore the unused communication path 40 is closed by a closing plug 82. Therefore, each communication passage 40 is provided with a screw corresponding to the screw diameter of the closing plug 82. Other configurations are the same as those in the above embodiment.

Therefore, it is possible to measure the output of the ultraviolet rays actually radiated from the ultraviolet radiation portion without worrying about the dirt on the protective tube 22. In addition, the attachment position of the ultraviolet sensor 33 can be changed by the number of the communication paths 40 provided, and the degree of freedom of attachment of the ultraviolet sensor 33 can be increased.

この被覆部材９０の第４実施例の場合には、前述した実施例の効果に加えて、保護管２２を介することなく紫外線ランプ２０の電極５３ｂに近い部分を紫外線センサ３３で直接測定することができるため、保護管２２の汚れを気にすることなく、実際に紫外線放射部から放射されている紫外線の出力を測定することができる。しかも、紫外線ランプ２０のガラス管が延在する方向から紫外線の出力を測定することができる。 In the case of the fourth embodiment of the covering member 90, in addition to the effect of the above-described embodiment, a portion near the electrode 53b of the ultraviolet lamp 20 can be directly measured by the ultraviolet sensor 33 without passing through the protective tube 22.
