本発明は、紫外線照射によって有機物汚れを分解し除去する有機物汚れ除去装置に関し、例えば鍋等の焦げ付きを除去し得る装置に関する。 TECHNICAL FIELD The present invention relates to an organic stain remover that decomposes and removes organic stains by irradiating ultraviolet rays, and more particularly to an apparatus capable of removing scorched pots and the like.

特許文献１には、焼き網の焼き焦げを除去するための装置が開示されている。そこに示された焼き焦げ除去装置においては、洗浄水を入れた水槽内に紫外線ランプ及びオゾン噴出器具を設置し、該水槽内に焼き網を浸漬した状態で紫外線を照射することにより前処理を行い、後処理として、水槽内の洗浄水にオゾン含有の空気を供給することにより、該焼き網に付着した焼き焦げ（有機物）を酸化分解するようにしている。 Patent Document 1 discloses an apparatus for removing charred food from a gridiron.

特開２００６－５１０８９号公報JP-A-2006-51089

上述したような従来の焼き焦げ除去装置は、焼き網（清浄化対象物）を水中に浸漬させる構造からなるため、焼き網のような小型若しくは平面的なものには適しているが、鍋のような嵩張るものには適していない。また、水槽及びオゾン発生装置が必要であるため、装置が大がかりとなり、コスト高にもなる。 The conventional scorch removal device as described above has a structure in which a grill (object to be cleaned) is immersed in water, so it is suitable for a small or flat one such as a grill, but it is suitable for a pot. Not suitable for bulky items like Moreover, since a water tank and an ozone generator are required, the apparatus becomes large-scaled and the cost is high.

本発明は、鍋のような嵩張る形態の処理対象における有機物汚れ（例えば焦げ付き）を除去するのに適した有機物汚れ除去装置を提供しようとするものである。 SUMMARY OF THE INVENTION It is an object of the present invention to provide an organic stain removing apparatus suitable for removing organic stains (eg, burns) from a bulky processing object such as a pot.

本発明に係る有機物汚れ除去装置は、底面が開口面である筐体と、放射した紫外線が少なくとも前記開口面を指向するように、前記筐体内に配置された紫外線光源と、前記筐体内において前記紫外線光源の周辺に配置された反射体であって、前記開口面に対応する面が開口したドーム形状からなり、前記紫外線光源から発生された紫外線を前記開口面に向けて反射する構造からなるものと、前記筐体の前記開口面の周囲に配置された、耐紫外線材料からなる柔軟部材とを備え、前記開口面が処理対象に対する紫外線照射領域であり、該処理対象に前記筐体を被せることにより前記開口面に該処理対象を配置し、該処理対象に前記筐体を被せた状態において前記柔軟部材を介して前記開口面の周囲を閉じることができるように構成されており、紫外線照射によって該処理対象に存在する有機物汚れを分解することを特徴するものである。 An organic dirt removing apparatus according to the present invention comprises a housing having an opening on the bottom surface, an ultraviolet light source arranged in the housing so that emitted ultraviolet rays are directed at least toward the opening, and A reflector disposed around an ultraviolet light source, which has a dome shape with an opening on a surface corresponding to the opening surface, and has a structure for reflecting ultraviolet rays generated from the ultraviolet light source toward the opening surface. and a flexible member made of an ultraviolet-resistant material disposed around the opening surface of the housing, wherein the opening surface is an ultraviolet irradiation area for an object to be processed, and the object to be processed is covered with the housing. The object to be processed is placed on the opening surface by the method, and in a state in which the housing is placed on the object to be processed, the periphery of the opening surface can be closed via the flexible member. It is characterized by decomposing organic stains present on the object to be treated.

鍋のような嵩張るものであっても、焦げ付きを生じる箇所は、鍋底のような特定の部分的箇所である。そこで、本発明によれば、筐体の開口面が処理対象（例えば鍋底）に面するように、簡便に該処理対象に筐体を被せることで、該処理対象（例えば鍋底）に集中的に紫外線を照射し、紫外線による有機物分解機能により有機物汚れ（例えば焦げ付き）を除去することができる。したがって、全体としてコンパクトな小型化した構成からなる有機物汚れ除去装置を提供することができ、鍋のような嵩張る形態の処理対象における部分的な有機物汚れ（例えば焦げ付き）を除去するのに適する。また、筐体は、特定の一面（例えば底面）を開口面とし、その他の部位は密閉構造とすることができ、かつ、処理対象に筐体を被せた状態において柔軟部材を介して開口面の周囲を閉じることができるように構成されているので、外部周辺環境への紫外線漏洩を抑止した安全設計を容易に採用し得る。 Even in a bulky object such as a pot, the portion where scorching occurs is a specific partial portion such as the bottom of the pot. Therefore, according to the present invention, by simply covering the processing object with the housing so that the opening surface of the housing faces the processing object (for example, the pot bottom), the processing object (for example, the pot bottom) can be concentrated. By irradiating ultraviolet rays, organic matter stains (for example, burning) can be removed by the organic matter decomposition function of the ultraviolet rays. Therefore, it is possible to provide an organic dirt removing apparatus having a compact and miniaturized configuration as a whole, and is suitable for removing partial organic dirt (for example, burnt) on a bulky processing object such as a pot. In addition, the housing can have a specific one surface (for example, the bottom surface) as an opening surface and the other portions as a closed structure. Since it is configured so that the surroundings can be closed , it is possible to easily adopt a safety design that prevents ultraviolet rays from leaking into the external surrounding environment.

図１において、本発明の一実施例に係る有機物汚れ除去装置１は、一例として、鍋底の焦げ付きを除去する焦げ付き除去装置として機能し得るものである。この有機物汚れ除去装置１（以下、焦げ付き除去装置１とも言う）は、筐体１０を有しており、この筐体１０は、略円筒形を成しており、その一面（例えば底面）が開口１０ａ（以下、開口面１０ａという）となっている。筐体１０の内部には、放射した紫外線が少なくとも該開口面１０ａを指向するように、紫外線光源１１が配置されている。また、筐体１０の内部には、紫外線光源１１の周辺に反射体１２が配置されており、該反射体１２により該紫外線光源１１から放射された紫外線光が反射される。一例として、反射体１２は、お椀を伏せたような、その底部が開口したドーム状若しくは略半球状の形状からなる凹曲面の反射鏡であり、ステンレス又はアルミニウムのような光透過性を持たない光反射性の材料で好ましく形成される。勿論、反射体１２の底部の開口は筐体１０の開口面１０ａに重なる。紫外線光源１１（例えば球形の紫外線ランプ）は、反射体１２（反射鏡）の凹曲面反射空間内の適宜位置に配置され、放射した紫外線が反射体１２の底部の開口つまり筐体１０の開口面１０ａから下方に向けて、直接的に及び反射体１２で適宜反射されて、外部に放光される。すなわち、筐体１０の開口面１０ａが処理対象（例えば鍋底）に対する紫外線照射領域となる。筐体１０内の適宜箇所（好ましくは反射体１２の凹曲面反射空間の外）に紫外線光源１１を点灯するための点灯装置１３が配置される。点灯装置１３としては電子回路を用いた高周波発生装置や高電圧発生装置などを適宜用いてよい。 In FIG. 1, an organic dirt removing device 1 according to an embodiment of the present invention can function as a scorching removing device for removing scorching on the bottom of a pan, as an example. This organic dirt removing device 1 (hereinafter also referred to as the sticking removing device 1) has a housing 10. This housing 10 has a substantially cylindrical shape, and one side (for example, the bottom) is open. 10a (hereinafter referred to as opening surface 10a). Inside the housing 10, an ultraviolet light source 11 is arranged so that emitted ultraviolet rays are directed at least toward the opening surface 10a. A reflector 12 is arranged around the ultraviolet light source 11 inside the housing 10 , and the ultraviolet light emitted from the ultraviolet light source 11 is reflected by the reflector 12 . As an example, the reflector 12 is a dome-shaped or substantially hemispherical reflector with an open bottom, which looks like an upside-down bowl, and has a concave curved surface, and does not have light transmittance like stainless steel or aluminum. It is preferably made of a light-reflecting material. Of course, the bottom opening of the reflector 12 overlaps the opening surface 10 a of the housing 10 . The ultraviolet light source 11 (for example, a spherical ultraviolet lamp) is placed at an appropriate position within the reflecting space of the concave curved surface of the reflector 12 (reflector), and the emitted ultraviolet light reaches the opening at the bottom of the reflector 12, that is, the opening surface of the housing 10. The light is emitted downward from 10a directly and appropriately reflected by the reflector 12 to the outside. That is, the opening surface 10a of the housing 10 becomes an ultraviolet irradiation area for the object to be processed (for example, the bottom of a pan). A lighting device 13 for lighting the ultraviolet light source 11 is disposed at an appropriate location within the housing 10 (preferably outside the concave curved reflection space of the reflector 12). As the lighting device 13, a high frequency generator or a high voltage generator using an electronic circuit may be used as appropriate.

紫外線光源１１の発光空間（つまり反射体１２の凹曲面反射空間）内に外部から水分を導入するための水分導入管１４を設けてもよい。導入管１４の上部入口１４ａから水を供給し、下部出口１４ｂから紫外線光源１１の発光空間（反射体１２の凹曲面反射空間）内に水分を排出する。一例として、筐体１０の上面に電動ポンプ（不図示）を配置し、上部入口１４ａから水を導入管１４内に供給してよい。また、導入管１４の下部出口１４ｂにシャワーノズル（不図示）を設け、水分を霧状に噴霧するようにしてもよい。また、該電動ポンプ（不図示）をタイマ運転によって間欠的に駆動することにより、プログラムされた時間間隔で適量の水分を間欠的に導入管１４に供給するようにしてもよい。 A moisture introduction pipe 14 for introducing moisture from the outside may be provided in the light emitting space of the ultraviolet light source 11 (that is, the concave curved reflection space of the reflector 12). Water is supplied from the upper inlet 14a of the introduction pipe 14, and the water is discharged from the lower outlet 14b into the light emitting space of the ultraviolet light source 11 (concave reflection space of the reflector 12). As an example, an electric pump (not shown) may be arranged on the upper surface of the housing 10 to supply water into the introduction pipe 14 from the upper inlet 14a. Also, a shower nozzle (not shown) may be provided at the lower outlet 14b of the introduction pipe 14 to spray water in the form of mist. Further, by intermittently driving the electric pump (not shown) by timer operation, an appropriate amount of water may be intermittently supplied to the introduction pipe 14 at programmed time intervals.

紫外線光源１１としては、希ガスやハロゲンガスなどを封入したエキシマ発光ランプ、ＵＶ－ＬＥＤ、低圧水銀ランプなどが適している。あるいは、高速電子を半導体に照射して紫外線を放射する電子管タイプの紫外線放射光源を紫外線光源１１として用いてもよい。一例として、略120nm乃至400nmの範囲の波長成分を含む紫外線を放射する。図３は、参考として、エキシマ発光における封入ガスと放射紫外線の波長及びそのエネルギーの関係の一例を示す表である。封入ガスの組み合わせを適宜に設定することにより、望みの波長成分を含む紫外線を放射するように構成することができる。例えば、紫外線光源１１は、108nm、126nm、146nm、158nm、172nm、193nm、222nm、248nm、254nm、365nm及びこれらの近傍の波長成分のいずれか少なくとも１つを含む紫外線を放射するように構成するとよい。あるいは、これら特定の波長成分を含む紫外線発光をベースにして更に蛍光体により波長変換を行い、より幅広い放射スペクトル幅を持つ紫外線を発生しうるように、紫外線光源１１を構成してもよい。 As the ultraviolet light source 11, an excimer light-emitting lamp, a UV-LED, a low-pressure mercury lamp, or the like filled with rare gas or halogen gas is suitable. Alternatively, an electron tube type ultraviolet radiation source that emits ultraviolet rays by irradiating a semiconductor with high-speed electrons may be used as the ultraviolet light source 11 . As an example, it emits ultraviolet rays containing wavelength components in the range of approximately 120 nm to 400 nm. FIG. 3 is a table showing, for reference, an example of the relationship between the enclosed gas in excimer light emission and the wavelength and energy of emitted ultraviolet rays. By appropriately setting the combination of filled gases, it is possible to radiate ultraviolet rays containing desired wavelength components. For example, the ultraviolet light source 11 may be configured to emit ultraviolet light containing at least one of wavelength components of 108 nm, 126 nm, 146 nm, 158 nm, 172 nm, 193 nm, 222 nm, 248 nm, 254 nm, 365 nm and their vicinity. . Alternatively, the ultraviolet light source 11 may be configured so as to generate ultraviolet rays having a broader emission spectrum width by further performing wavelength conversion using phosphors based on the emitted ultraviolet rays containing these specific wavelength components.

図２に示すように、本実施例に係る焦げ付き除去装置１の使用時においては、筐体１の開口面１０ａを下にして鍋２０の底（処理対象）に該筐体１を被せ、該開口面１０ａが処理対象である鍋２０の底に面するようにする。この状態で点灯装置１３を介して紫外線光源１１を点灯し、紫外線光源１１から放射された紫外線を鍋２０の底（処理対象）に照射する。鍋２０の底に付着した焼け焦げは有機物であるから、紫外線の照射によって該有機物が分解され、これにより鍋２０の底の焦げ付きを除去することができる。 As shown in FIG. 2, when using the burnt removal device 1 according to the present embodiment, the opening surface 10a of the housing 1 is placed downward, and the housing 1 is placed on the bottom (to be processed) of the pan 20. The opening surface 10a faces the bottom of the pot 20 to be treated. In this state, the ultraviolet light source 11 is turned on via the lighting device 13, and the ultraviolet light emitted from the ultraviolet light source 11 is irradiated to the bottom of the pan 20 (to be processed). Since the scorch sticking to the bottom of the pot 20 is organic matter, the organic matter is decomposed by the irradiation of the ultraviolet rays, thereby removing the scorching of the bottom of the pot 20. - 特許庁

図４は、参考として、各種の有機結合における結合エネルギー（平均エネルギー）の一例をキロカロリ毎モル（kcal/mol）と光波長（nm）で表す表である。この結合エネルギーの光波長よりも短い波長の光（紫外線）を有機物に照射することにより、該有機物の結合が切れ、炭酸ガスや水蒸気或いは窒素ガスなどにガス化され、もって該有機物が消滅除去される。 As a reference, FIG. 4 is a table showing an example of binding energy (average energy) in various organic bonds in kilocalories per mol (kcal/mol) and light wavelength (nm). By irradiating the organic matter with light (ultraviolet rays) having a wavelength shorter than the light wavelength of this binding energy, the bonds of the organic matter are broken and the organic matter is gasified into carbon dioxide gas, water vapor, or nitrogen gas, thereby annihilating and removing the organic matter. be.

筐体１０の紫外線発光空間内に水分を導入するための水分導入管１４はオプションとして設けられるものであり、発明の必須の要素ではない。水分導入管１４を介して筐体１０の紫外線発光空間内に水分を導入することにより、水分のOH基が活性化されて焦げ付きを分解除去するとともに、焦げ付きに通常存在する塩分が水分中に溶け出して焦げ付きを除去するスピードが速くなり、結果的に焦げ付き除去効率を促進することができる。なお、これら塩分は水に溶け出し、鍋２０の底に溜まるが、最後に洗い流すことで完全に除去できる。 A moisture introduction pipe 14 for introducing moisture into the ultraviolet emission space of the housing 10 is provided as an option and is not an essential element of the invention. By introducing moisture into the ultraviolet light emitting space of the housing 10 through the moisture introduction pipe 14, the OH group of the moisture is activated to decompose and remove the charring, and the salt normally present in the charring dissolves in the water. The speed of taking out and removing the scorch is increased, and as a result, the efficiency of removing the scorch can be promoted. These salts dissolve in water and accumulate at the bottom of the pot 20, but can be completely removed by washing them off at the end.

なお、本実施例に係る焦げ付き除去装置（すなわち、有機物汚れ除去装置）１が正規の使用状態にあることを検出するために、処理対象検出回路１５を付属して設けるとよい。この処理対象検出回路１５は、筐体１０の開口面１０ａに処理対象（例えば鍋２０の底）が配置されたことを検知するものであり、処理対象である鍋２０の底が筐体１０の開口面１０ａ（すなわち紫外線照射領域）に配置されていることを該検出装置１５が検知していることを条件に、紫外線光源１１の点灯を許可する。つまり、焦げ付き除去装置１に付属している点灯スイッチ（不図示）をオンしても、処理対象検出回路１５から処理対象である鍋２０の底を検出していることを示す信号が与えられない限り、点灯装置１３は紫外線光源１１に点灯電力を供給しない。これにより、筐体１０の開口面１０ａ（すなわち紫外線照射領域）が処理対象である鍋２０の底によって閉鎖された状態であるときのみ、紫外線光源１１が点灯されることになり、外部周辺環境への紫外線の漏洩を確実に防止することができる。なお、処理対象検出回路１５の具体的構成は任意であり、例えば、マイクロリミットスイッチによる機械的接触による検出方法、あるいは超音波反射等による非接触的な物体検出方法、あるいは物体の有無を検知する光学的検出方法、あるいは焦げ付きの有無を反射光の明暗によって検知する光学的検出方法など、任意の検出方法を採用する検出装置を利用し得る。この処理対象検出回路１５は、紫外線が人体や周辺器具類に悪影響を与えることがないように、外部周辺環境への紫外線の漏洩を防止する。 In order to detect that the burnt-on removal device (that is, the organic stain removal device) 1 according to the present embodiment is in a normal operating state, a process target detection circuit 15 may be additionally provided. The processing target detection circuit 15 detects that a processing target (for example, the bottom of the pan 20) is placed on the opening surface 10a of the housing 10. Lighting of the ultraviolet light source 11 is permitted on the condition that the detection device 15 detects that it is arranged on the opening surface 10a (that is, the ultraviolet irradiation area). In other words, even if a lighting switch (not shown) attached to the burn removal device 1 is turned on, the processing target detection circuit 15 does not give a signal indicating that the bottom of the pot 20 to be processed is detected. As long as the lighting device 13 does not supply lighting power to the ultraviolet light source 11 . As a result, the ultraviolet light source 11 is turned on only when the opening surface 10a (that is, the ultraviolet irradiation area) of the housing 10 is closed by the bottom of the pot 20 to be treated, and the ultraviolet light source 11 is turned on. leakage of ultraviolet rays can be reliably prevented. The specific configuration of the processing target detection circuit 15 is arbitrary. For example, a detection method based on mechanical contact using a micro limit switch, a non-contact object detection method based on ultrasonic wave reflection, or the presence or absence of an object is detected. A detection device that employs any detection method, such as an optical detection method or an optical detection method that detects the presence or absence of scorching based on the brightness of reflected light, can be used. This processing object detection circuit 15 prevents the ultraviolet rays from leaking into the external surrounding environment so that the ultraviolet rays do not adversely affect the human body or peripheral equipment.

また、反射体１２は、紫外線光源１１から発生された紫外線を、透過させることなく、筐体１０の開口面１０ａに向けて反射する構造であるため、開口面１０ａ以外の部位から外部周辺環境に紫外線が漏洩することを防止するのに寄与する。さらに、開口面１０ａ以外の部位から外部周辺環境に紫外線が漏洩することを防止するために、紫外線を遮断する材料で筐体１０を構成するとよい。例えば、筐体１０の素材を金属製とする、あるいはプラスチック製の筐体１０の少なくとも内表面に紫外線遮断材料（例えば酸化亜鉛あるいは酸化チタンなど）を塗布する、あるいは筐体１０のプラスチック素材内に該紫外線遮断材料を混入したものを用いる、など適宜の形態を採用し得る。 In addition, since the reflector 12 has a structure in which the ultraviolet rays generated from the ultraviolet light source 11 are reflected toward the opening surface 10a of the housing 10 without transmitting the ultraviolet rays, the ultraviolet rays are reflected from a portion other than the opening surface 10a to the external surrounding environment. It contributes to preventing ultraviolet rays from leaking. Furthermore, in order to prevent ultraviolet rays from leaking into the surrounding environment from a portion other than the opening surface 10a, the housing 10 may be made of a material that blocks ultraviolet rays. For example, the housing 10 is made of metal, or at least the inner surface of the plastic housing 10 is coated with an ultraviolet blocking material (such as zinc oxide or titanium oxide), or the plastic material of the housing 10 contains An appropriate form can be employed, such as using a material in which the ultraviolet blocking material is mixed.

なお、紫外線は酸素をオゾン化するので、紫外線光源１１から発生された紫外線によって筐体１０の発光空間内でオゾンが生成され、該生成されたオゾンの作用によっても鍋２０の焦げ付きを酸化除去する効果を得ることができる。その場合、開口面１０ａの周囲における筐体１０の下端部と鍋２０の底との接触が密でなければ、その隙間からオゾンが周辺環境に漏れ出る可能性があり、人によっては不快なオゾン臭が気になるかもしれない。そこで、オゾン臭が周辺に漏れるのを防ぐ為に、筐体１０の開口面１０ａの周囲に、耐紫外線材料からなる柔軟部材１６を配置するとよい。これにより、処理対象である鍋２０の底に筐体１０を被せた状態において該柔軟部材１６が鍋底に密接するようになり、接触箇所の隙間からオゾンが周辺環境に漏れ出すおそれがなくなる。 Since the ultraviolet rays ozonize oxygen, the ultraviolet rays emitted from the ultraviolet light source 11 generate ozone in the light emitting space of the housing 10, and the action of the generated ozone also oxidizes and removes the scorched pot 20. effect can be obtained. In that case, if the contact between the lower end of the housing 10 and the bottom of the pot 20 around the opening surface 10a is not tight, ozone may leak into the surrounding environment through the gap, which may be uncomfortable for some people. The smell may bother you. Therefore, in order to prevent the smell of ozone from leaking to the surroundings, it is preferable to arrange a flexible member 16 made of an ultraviolet-resistant material around the opening surface 10a of the housing 10. FIG. As a result, when the housing 10 is placed on the bottom of the pan 20 to be treated, the flexible member 16 comes into close contact with the bottom of the pan, eliminating the risk of ozone leaking into the surrounding environment through the gaps at the contact points.

点灯装置１３を駆動する電源としては、内臓バッテリーを用いる方法、あるいは電源コード（不図示）を介した接続によって商用電源を用いる方法など、適宜採用してよい。 As a power supply for driving the lighting device 13, a method using a built-in battery, a method using a commercial power supply by connection via a power cord (not shown), or the like may be adopted as appropriate.

本実施例の実験結果について説明すると、100Wの水銀放電を用いた紫外線光源１１を用いて、直径約30cm、深さ10cmのアルマイト製の鍋２０の焦げ付きに対して、5時間おきに10ccの水を導入しながら約1日間（25時間）照射した結果、該焦げ付きをほぼ完全に除去できた。これに対して、焦げ付きのある鍋を天日干しすることにより自然に焦げ付きを分解させる手法を採用した場合、該焦げ付きのある鍋を３週間（約500時間）野晒しにすることで焦げ付きほぼ除去できた（この間、鍋は太陽光や風雨に曝された）。ここから判ることは、本実施例によれば、天日干しに比べて、焦げ付き除去時間を凡そ20分の1に短縮することができた、ということである。 To explain the experimental results of this example, using an ultraviolet light source 11 using a 100 W mercury discharge, an alumite pot 20 with a diameter of about 30 cm and a depth of 10 cm was scorched. As a result of irradiating for about one day (25 hours) while introducing , the scorching could be almost completely removed. On the other hand, when a method of naturally decomposing the scorched pot by drying the pan with scorching in the sun is adopted, the scorching can be almost completely eliminated by exposing the pan with the scorching to the open air for 3 weeks (approximately 500 hours). (During this time the pot was exposed to sunlight and the elements). It can be seen from this that, according to this example, the scorching removal time could be shortened to about 1/20 compared to sun drying.

反射体１２の形態は、上記実施例に示したようなドーム形状に限らず、他の如何なる形態であってもよい。また、反射体１２は一体形状からなるものに限らず、分離された複数の反射片で構成されていてもよい。筐体１０の形状も、上記実施例に示したような円筒形状に限らず、他の如何なる形状（例えば立方体形状、ドーム形状、円錐又は角錐形状等）であってもよい。なお、反射体１２が完全なドーム形状等からなっていて、開口面１０ａ以外からは紫外線が漏洩しえない構造である場合は、筐体１０の壁面は紫外線を完全に遮蔽し得る構造（形状及び／又は材質）でなくてもよく、適宜、隙間があってもよい。反対に、反射体１２が完全なドーム形状等からなっておらず、反射体１２の適宜部位から筐体１０内に紫外線が漏洩し得るかもしれない構造であってもよく、その場合は、紫外線を完全に遮蔽し得る構造（形状及び／又は材質）で筐体１０の壁面を構成することにより、該筐体１０の壁面によって外部周辺環境への紫外線の漏洩を確実に防止できる。 The shape of the reflector 12 is not limited to the dome shape shown in the above embodiment, and may be any other shape. In addition, the reflector 12 is not limited to the integral shape, and may be composed of a plurality of separated reflecting pieces. The shape of the housing 10 is also not limited to the cylindrical shape shown in the above embodiments, and may be any other shape (for example, a cubic shape, a dome shape, a conical or pyramidal shape, etc.). If the reflector 12 has a complete dome shape or the like and has a structure that prevents the ultraviolet rays from leaking from any part other than the opening surface 10a, the wall surface of the housing 10 has a structure (shape) that can completely block the ultraviolet rays. and/or material), and there may be gaps as appropriate. On the contrary, the reflector 12 may not have a complete dome shape or the like, and may have a structure in which the ultraviolet rays may leak into the housing 10 from an appropriate portion of the reflector 12. By constructing the wall surface of the housing 10 with a structure (shape and/or material) that can completely shield the ultraviolet rays, the wall surface of the housing 10 can reliably prevent ultraviolet rays from leaking into the surrounding environment.

なお、請求項１で言及していない構成要素（例えば、水分導入管１４、処理対象検出回路１５、柔軟部材１６等）は、本発明の実施にあたって適宜省略してよい。本実施例に係る有機物汚れ除去装置１は、鍋２０の底に付着した有機物の焦げ付きの除去に限らず、焼き網その他の調理器具若しくは道具類に付着した有機物の焦げ付きを除去するために使用できるし、焦げ付きに限らず、その他の有機物の汚れを分解し除去するためにも使用できる。 Components not mentioned in claim 1 (for example, the moisture introduction pipe 14, the processing target detection circuit 15, the flexible member 16, etc.) may be omitted as appropriate when implementing the present invention.
