本発明の請求項1に記載の油煙浄化デバイスは、少なくとも放電電極と四角平板状の対向電極とを有し、前記対向電極の表面が半導電性を有しており、前記対向電極に通電して発熱させるための高圧電極とアース電極を、前記対向電極の対辺に設けたことを特徴とする油煙浄化デバイスである。   The oil and smoke purification device according to claim 1 of the present invention has at least a discharge electrode and a square plate-like counter electrode, the surface of the counter electrode has semiconductivity, and the counter electrode is energized. The oil smoke purification device is characterized in that a high-voltage electrode and a ground electrode for generating heat are provided on opposite sides of the counter electrode.

上記構成により、対向電極上に高圧電極とアース電極を設けることができ、ヒータも不要で対向電極の寸法を大きくすることなく、小型な油煙浄化デバイスを得ることができる。   With the above configuration, a high-voltage electrode and a ground electrode can be provided on the counter electrode, a heater is not required, and a small oil smoke purification device can be obtained without increasing the size of the counter electrode.

また、半導電性を有する対向電極に高圧電極とアース電極を、対向電極の対辺に設けて電位差を与えることで、対向電極に電流を流して発熱させ、対向電極の表面に堆積した油を融解させて除去することで、対向電極に油が堆積するのを防止してメンテナンス性を高めた油煙浄化デバイスを得ることができる。   In addition, a high-voltage electrode and a ground electrode are provided on the opposite side of the semiconductive electrode, and a potential difference is applied to the opposite side of the counter electrode, so that a current flows through the counter electrode to generate heat and melt the oil deposited on the surface of the counter electrode. By removing it, it is possible to obtain an oil smoke purification device that prevents oil from accumulating on the counter electrode and has improved maintainability.

本発明の請求項2に記載の油煙浄化デバイスは、高圧電極とアース電極以外の対向電極の表面抵抗率が106Ω/□以上から1010Ω/□未満の範囲であることを特徴とする請求項1に記載の油煙浄化デバイスである。 The oil and smoke purification device according to claim 2 of the present invention is characterized in that the surface resistivity of the counter electrode other than the high-voltage electrode and the ground electrode is in the range of 10 6 Ω / □ or more to less than 10 10 Ω / □. The oil smoke purification device according to claim 1.

対向電極の表面抵抗率を上記の範囲とすることにより、対向電極の表面が半導電性となり、電流を流すことにより表面抵抗率に依存した発熱量が得られる。対向電極の表面を発熱させることにより、対向電極の表面に堆積した油を融解させて除去することができ、対向電極に油が堆積するのを防止してメンテナンス性を高めた油煙浄化デバイスを得ることができる。   By setting the surface resistivity of the counter electrode within the above range, the surface of the counter electrode becomes semiconductive, and an amount of heat generated depending on the surface resistivity can be obtained by passing a current. By generating heat on the surface of the counter electrode, the oil deposited on the surface of the counter electrode can be melted and removed, and an oil smoke purification device with improved maintainability by preventing oil from accumulating on the counter electrode is obtained. be able to.

また、対向電極の表面抵抗率が106〜1010Ω/□の範囲であるため、放電電極と対向電極を近接させても、火花放電は発生しない。また、放電電極と接地電極とを近接させることができるので、小型化を図ることができ、しかも高い集油性能を確保することができる。 Further, since the surface resistivity of the counter electrode is in the range of 10 6 to 10 10 Ω / □, no spark discharge occurs even when the discharge electrode and the counter electrode are brought close to each other. Further, since the discharge electrode and the ground electrode can be brought close to each other, the size can be reduced, and high oil collecting performance can be ensured.

本発明の請求項3に記載の油煙浄化デバイスは、放電電極への電圧印加と、高圧電極への電圧印加とを切り替える電圧印加切替手段を設けたことを特徴とする請求項1または2に記載の油煙浄化デバイス。   The oil and smoke purification device according to claim 3 of the present invention is provided with voltage application switching means for switching between voltage application to the discharge electrode and voltage application to the high-voltage electrode. Oil smoke purification device.

放電電極と高圧電極への電圧印加を同時に行った場合、放電電極と高圧電極の距離が近い箇所で電界の干渉が生じ、放電電極の一部から放電が生じなくなり、集油性能が低下する可能性がある。放電電極への電圧印加と、高圧電極への電圧印加とを切り替える電圧印加切替手段を設けることにより、油煙浄化デバイスを運転しているときは放電電極に電圧を印加して集油し、油煙浄化デバイスを停止してメンテナンスモード等になったときは高圧電極に電圧を印加して対向電極に堆積した油を融解させて除去することで、集油性能の維持と高いメンテナンス性の確保を両立させることができる。   When voltage is applied to the discharge electrode and the high-voltage electrode at the same time, electric field interference occurs at a location where the distance between the discharge electrode and the high-voltage electrode is short, so that discharge does not occur from a part of the discharge electrode, and oil collection performance may be reduced. There is sex. By providing voltage application switching means to switch between voltage application to the discharge electrode and voltage application to the high voltage electrode, when operating the oil smoke purification device, voltage is applied to the discharge electrode to collect oil and oil smoke purification When the device is stopped and enters the maintenance mode, etc., by applying a voltage to the high-voltage electrode to melt and remove the oil deposited on the counter electrode, both oil retention performance and high maintainability can be ensured. be able to.

本発明の請求項4に記載の油煙浄化デバイスは、対向電極は、少なくとも四酸化三鉄を含むセラミックスからなることを特徴とする請求項1から3のいずれかに記載の油煙浄化デバイスである。   The oil smoke purification device according to claim 4 of the present invention is the oil smoke purification device according to any one of claims 1 to 3, wherein the counter electrode is made of a ceramic containing at least triiron tetroxide.

対向電極をセラミックスで構成することにより、コロナ放電に伴って発生するオゾン等に対する耐久性を高めることができ、品質が劣化しにくい。   By configuring the counter electrode with ceramics, durability against ozone or the like generated with corona discharge can be enhanced, and quality is unlikely to deteriorate.

また四酸化三鉄は、温度上昇に伴って物質固有の値である体積抵抗率が小さくなるという特性(熱活性型電気伝導性)を有している。そのため、高圧電極に電圧を印加して対向電極に電流を流すと、それに伴う発熱により、四酸化三鉄を含むセラミックスからなる対向電極の表面抵抗率は、四酸化三鉄の体積抵抗率の低下に伴って小さくなり、さらに電流が大きくなり、さらに発熱量が大きくなる。   In addition, triiron tetroxide has a characteristic (thermally active electrical conductivity) that the volume resistivity, which is a value unique to a substance, decreases with increasing temperature. Therefore, when a voltage is applied to the high-voltage electrode and a current is passed through the counter electrode, the surface resistivity of the counter electrode made of ceramics containing triiron tetroxide is reduced due to the heat generation associated with it. With this, the current becomes smaller, the current becomes larger, and the heat generation amount becomes larger.

したがって、より短い通電時間で対向電極の表面温度を上昇させることができ、対向電極に堆積した油を短時間で融解させて除去することが可能となる。   Therefore, the surface temperature of the counter electrode can be increased in a shorter energization time, and the oil deposited on the counter electrode can be melted and removed in a short time.

本発明の請求項5に記載の油煙浄化デバイスは、対向電極の表面に、油分解促進触媒を添着させたことを特徴とする請求項1から4のいずれかに記載の油煙浄化デバイスである。   The oil smoke purification device according to claim 5 of the present invention is the oil smoke purification device according to any one of claims 1 to 4, wherein an oil decomposition promoting catalyst is attached to the surface of the counter electrode.

これにより、対向電極に付着した油の熱分解を促進することができ、対向電極に堆積した油を短時間で除去することが可能となる。   Thereby, the thermal decomposition of the oil adhering to the counter electrode can be promoted, and the oil deposited on the counter electrode can be removed in a short time.

本発明の請求項6に記載の油煙浄化デバイスは、対向電極の表面温度を検出する温度検知手段を備え、前記対向電極の表面温度が100度を超えようとした場合に、前記高圧電極への印加電圧を制限または停止することを特徴とする請求項1から5のいずれかに記載の油煙浄化デバイスである。   The oil smoke purification device according to claim 6 of the present invention includes temperature detection means for detecting the surface temperature of the counter electrode, and when the surface temperature of the counter electrode is about to exceed 100 degrees, 6. The oil smoke purification device according to claim 1, wherein the applied voltage is limited or stopped.

表面が半導電性の対向電極に電流を流し続けた場合に、対向電極の温度が必要以上に高くなりすぎる恐れがある。多くの油は100度以下で溶けて粘度が低下して除去しやすくなる。対向電極の表面温度を検出する温度検知手段を備え、対向電極の表面温度が100度を超えようとした場合に、高圧電極への印加電圧を制限または停止して表面温度の上昇を防止することにより、安全性とメンテナンス性の確保を両立することができる。   If a current continues to flow through the counter electrode having a semiconductive surface, the temperature of the counter electrode may become unnecessarily high. Many oils dissolve at less than 100 degrees, and the viscosity decreases, making it easier to remove. It is equipped with temperature detection means for detecting the surface temperature of the counter electrode, and when the surface temperature of the counter electrode is going to exceed 100 degrees, the applied voltage to the high voltage electrode is limited or stopped to prevent the surface temperature from rising. As a result, both safety and maintainability can be ensured.

本発明の請求項7に記載の油煙浄化装置は、加熱調理器具による調理等で発生する油煙や臭気を吸引する吸気口と、前記吸気口と連通する風路と、前記風路に空気を流通させる送風手段と、前記風路と連通する排気口とを有し、前記風路に油煙除去手段を設け、前記油煙除去手段として請求項1から6のいずれかに記載の油煙浄化デバイスを設けたことを特徴とする油煙浄化装置である。   According to a seventh aspect of the present invention, there is provided an oil smoke purification apparatus comprising: an air inlet that sucks oil smoke and odor generated by cooking with a cooking utensil; an air passage that communicates with the air inlet; and air that flows through the air passage An air outlet that communicates with the air passage, oil smoke removing means is provided in the air passage, and the oil smoke purification device according to any one of claims 1 to 6 is provided as the oil smoke removing means. This is an oil smoke purification device.

小型でメンテナンス性を高めた油煙浄化デバイスを搭載することにより、装置寸法が小型化され、かつメンテナンス性を向上させた油煙浄化装置を得ることができる。   By mounting the oil smoke purification device having a small size and improved maintainability, it is possible to obtain an oil smoke purification device having a reduced apparatus size and improved maintainability.

本発明の請求項8に記載の油煙浄化装置は、油煙除去手段の下流に、着脱可能な油受けを設けたことを特徴とする請求項7に記載の油煙浄化装置である。   The oil smoke purification device according to claim 8 of the present invention is the oil smoke purification device according to claim 7, wherein a removable oil receiver is provided downstream of the oil smoke removal means.

これにより、必要に応じてユーザーが油受けを取り外し、溜まった油を捨てることができるようになり、メンテナンスが容易な油煙浄化装置を得ることができる。   As a result, the user can remove the oil receiver as needed to discard the accumulated oil, and an oil smoke purification device with easy maintenance can be obtained.

以下、本発明の実施の形態について図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(実施の形態1)
図1は本発明の実施の形態1における油煙浄化デバイスの模式図である。
(Embodiment 1)
FIG. 1 is a schematic diagram of an oil smoke purification device according to Embodiment 1 of the present invention.

図1に示すように、油煙浄化デバイス1は、高電圧(本実施の形態ではマイナス7kV)を印加する針状の放電電極2と、アースに接続された四角平板状の対向電極3とを、所定の間隔(例えば15〜20mm)を空けて交互に配置した構成となっている。油煙を含む空気が流入すると、放電電極2と対向電極3との間で生じさせたコロナ放電の領域を通過する際に油の粒子が帯電される。帯電された粒子は対向電極3上に捕集され、流出する空気は清浄なものとなる。   As shown in FIG. 1, the oil smoke purification device 1 includes a needle-like discharge electrode 2 for applying a high voltage (minus 7 kV in the present embodiment) and a square plate-like counter electrode 3 connected to the ground. It has a configuration in which predetermined intervals (for example, 15 to 20 mm) are alternately arranged. When air containing oil smoke flows in, oil particles are charged when passing through a region of corona discharge generated between the discharge electrode 2 and the counter electrode 3. The charged particles are collected on the counter electrode 3, and the outflowing air becomes clean.

本実施の形態では、放電電極2はコロナ放電による磨耗が小さい材質であるステンレス製であり、先端の尖った針状の部材をステンレス製の板上に複数配列したものを使用している。放電電極2は従来から様々な形態があり、例えば直径φ0.05mm〜φ0.3mm程度のワイヤ状の金属線や、板金を鋸歯状に打ち抜いたものなどがあり、どれを使用しても良い。   In the present embodiment, the discharge electrode 2 is made of stainless steel, which is a material with low wear due to corona discharge, and a plurality of needle-like members with sharp tips are arranged on a stainless steel plate. The discharge electrode 2 has conventionally various forms, for example, a wire-like metal wire having a diameter of about 0.05 mm to 0.3 mm, or a sheet metal punched into a sawtooth shape, and any of them may be used.

本実施の形態では、放電電極2の尖った先端が風下方向に向くように配置した。これはコロナ放電によって発生するイオン風の流れる方向と、油煙浄化デバイス1に流入する空気の流れる方向とを一致させることにより、衝突による風の流れの乱れを小さくし、空気中に含まれる油煙を帯電させる効率を高めるためである。   In this Embodiment, it has arrange | positioned so that the front-end | tip with a sharp tip of the discharge electrode 2 may face a leeward direction. This is because the flow direction of the ion wind generated by corona discharge matches the flow direction of the air flowing into the smoke purification device 1, thereby reducing the turbulence of the wind flow due to the collision, and reducing the smoke contained in the air. This is to increase the charging efficiency.

対向電極3の対辺、図1では上辺と下辺には、高圧電極4とアース電極5が設けられている。高圧電極4とアース電極5以外の対向電極3の表面は半導電性を有しており、その表面抵抗率は106Ω/□以上から1010Ω/□未満の範囲となっている。 A high voltage electrode 4 and a ground electrode 5 are provided on the opposite side of the counter electrode 3, in FIG. The surface of the counter electrode 3 other than the high-voltage electrode 4 and the ground electrode 5 has semiconductivity, and the surface resistivity is in the range from 10 6 Ω / □ to less than 10 10 Ω / □.

表面抵抗率の測定は、以下の方法で行った。   The surface resistivity was measured by the following method.

円柱状の主電極(直径d、単位はcm)と、主電極の周りを取り囲むようにリング状の対電極(リングの内径D、単位はcm)を、距離が一定となるように試験片上に置く。主電極と試験片の間には接触抵抗を減らすために、導電性ゴムを挟む。次に主電極には0V(アースに接続)、対電極には1000Vを印加し、その間に流れる電流を測定し、表面抵抗Rを算出する。算出したRと、試験片上で電流の流れる方向の距離Lと、電流の流れ方向と垂直方向の電極の長さWから表面抵抗率ρsを求める方法である。
ρs=R×W/L
W=π(D+d)
L=D−d
A cylindrical main electrode (diameter d, unit is cm) and a ring-shaped counter electrode (ring inner diameter D, unit is cm) so as to surround the main electrode are placed on the test piece so that the distance is constant. Put. Conductive rubber is sandwiched between the main electrode and the test piece to reduce contact resistance. Next, 0 V (connected to the ground) is applied to the main electrode, 1000 V is applied to the counter electrode, the current flowing between them is measured, and the surface resistance R is calculated. In this method, the surface resistivity ρs is obtained from the calculated R, the distance L in the direction of current flow on the test piece, and the length W of the electrode in the direction perpendicular to the direction of current flow.
ρs = R × W / L
W = π (D + d)
L = D−d

表面抵抗率の単位は[Ω/□]または単に[Ω]を使用するが、本特許では、単なる抵抗値との区別が容易な[Ω/□]を用いている。   The unit of surface resistivity is [Ω / □] or simply [Ω], but in this patent, [Ω / □] is used, which is easy to distinguish from a simple resistance value.

上記構成により、対向電極3上に高圧電極4とアース電極5を設けることができ、対向電極3の寸法を大きくすることなく、小型化された油煙浄化デバイス1を得ることができる。また、半導電性を有する対向電極3の表面に高圧電極4とアース電極5を設けて電位差を与えることで、対向電極3に電流を流し、対向電極3の表面で発熱させることができる。これにより、対向電極3の表面に堆積した油を融解させて流れ落ちやすくすることができ、対向電極3に油が堆積するのを防止してメンテナンス性を高めた油煙浄化デバイスを得ることができる。   With the above configuration, the high-voltage electrode 4 and the ground electrode 5 can be provided on the counter electrode 3, and the downsized oil smoke purification device 1 can be obtained without increasing the size of the counter electrode 3. Further, by providing the high-voltage electrode 4 and the ground electrode 5 on the surface of the counter electrode 3 having semiconductivity and applying a potential difference, a current can be passed through the counter electrode 3 to generate heat on the surface of the counter electrode 3. Thereby, the oil deposited on the surface of the counter electrode 3 can be melted and easily flowed down, and an oil smoke purification device with improved maintainability by preventing the oil from depositing on the counter electrode 3 can be obtained.

また、対向電極3の表面抵抗率を106Ω/□以上から1010Ω/□未満の範囲とすることにより、対向電極3の表面が半導電性となり、対向電極3の表面に設けた高圧電極4とアース電極5との間に電位差を与えて電流を流すことにより、表面抵抗率に依存した発熱量が得られる。対向電極3の表面を発熱させることにより、対向電極3の表面に堆積した油を融解させて流れ落ちやすくすることができ、対向電極3に油が堆積するのを防止してメンテナンス性を高めた油煙浄化デバイスを得ることができる。 Further, by setting the surface resistivity of the counter electrode 3 in the range of 10 6 Ω / □ or more to less than 10 10 Ω / □, the surface of the counter electrode 3 becomes semiconductive, and the high voltage provided on the surface of the counter electrode 3 is provided. By applying a potential difference between the electrode 4 and the ground electrode 5 to flow a current, a calorific value depending on the surface resistivity can be obtained. By causing the surface of the counter electrode 3 to generate heat, the oil deposited on the surface of the counter electrode 3 can be melted and flowed down easily, and oil smoke that prevents oil from accumulating on the counter electrode 3 and improves maintainability. A purification device can be obtained.

対向電極3の表面抵抗率が106Ω/□未満の領域では、意図せぬ付着物等により、放電電極2と対向電極3との距離が極端に小さくなった場合に、火花放電が生じ、油煙を帯電させる能力が低下し、結果として集油性能が低下する可能性がある。表面抵抗率が1010Ω/□以上の領域では、放電電極2と対向電極3との間でコロナ放電が生じにくくなり、油煙を帯電させる能力が低下し、結果として集油性能が低下する可能性がある。 In the region where the surface resistivity of the counter electrode 3 is less than 10 6 Ω / □, a spark discharge occurs when the distance between the discharge electrode 2 and the counter electrode 3 becomes extremely small due to unintended deposits, etc. The ability to charge oil smoke is reduced, and as a result, oil collection performance may be reduced. In a region where the surface resistivity is 10 10 Ω / □ or more, corona discharge is less likely to occur between the discharge electrode 2 and the counter electrode 3, and the ability to charge oil smoke is reduced, resulting in a decrease in oil collection performance. There is sex.

したがって、対向電極3の表面抵抗率を106〜1010Ω/□とすることにより、放電電極2と対向電極3を近接させても、火花放電が発生せず高い集油性能を発揮するとともに、放電電極2と対向電極3とを近接させて小型化した油煙浄化デバイス1を得ることができる。 Therefore, by setting the surface resistivity of the counter electrode 3 to 10 6 to 10 10 Ω / □, even if the discharge electrode 2 and the counter electrode 3 are brought close to each other, no spark discharge occurs and high oil collecting performance is exhibited. Thus, the oil smoke purification device 1 that is miniaturized by bringing the discharge electrode 2 and the counter electrode 3 close to each other can be obtained.

本実施の形態では、対向電極3の対辺、図1では上辺と下辺に高圧電極4とアース電極5を配置した。このように、放電電極2と高圧電極4とが近接している部分を極力少なくすることにより、放電電極2と高圧電極4とに同時に電圧を印加した場合でも、放電電極2と高圧電極4との電界の干渉領域を小さくすることができ、放電電極2から対向電極3へのコロナ放電を維持し、集油性能を発揮させることができる。   In the present embodiment, the high voltage electrode 4 and the ground electrode 5 are disposed on the opposite side of the counter electrode 3, and on the upper side and the lower side in FIG. 1. Thus, by reducing the portion where the discharge electrode 2 and the high voltage electrode 4 are close to each other as much as possible, even when a voltage is simultaneously applied to the discharge electrode 2 and the high voltage electrode 4, the discharge electrode 2 and the high voltage electrode 4 The electric field interference region can be made small, corona discharge from the discharge electrode 2 to the counter electrode 3 can be maintained, and oil collecting performance can be exhibited.

本発明の実施の形態では、対向電極3の材質として四酸化三鉄を含むセラミックスを用いている。対向電極3をセラミックスで構成することにより、コロナ放電に伴って発生するオゾン等に対する耐久性を高めることができ、品質が劣化しにくい。   In the embodiment of the present invention, ceramics containing triiron tetroxide is used as the material of the counter electrode 3. By configuring the counter electrode 3 with ceramics, durability against ozone or the like generated with corona discharge can be enhanced, and quality is unlikely to deteriorate.

また四酸化三鉄は、温度上昇に伴って物質固有の値である体積抵抗率が小さくなるという特性(熱活性型電気伝導性)を有している。そのため、高圧電極4に電圧を印加して対向電極3に電流を流すと、それに伴う発熱により、四酸化三鉄を含むセラミックスからなる対向電極3の表面抵抗率は、四酸化三鉄の体積抵抗率の低下に伴って小さくなり、さらに電流が大きくなり、さらに発熱量が大きくなる。   In addition, triiron tetroxide has a characteristic (thermally active electrical conductivity) that the volume resistivity, which is a value unique to a substance, decreases with increasing temperature. Therefore, when a voltage is applied to the high-voltage electrode 4 and a current is passed through the counter electrode 3, the surface resistivity of the counter electrode 3 made of ceramics containing triiron tetroxide is reduced by the volume resistance of triiron tetroxide. As the rate decreases, the current decreases, the current increases, and the amount of heat generation increases.

したがって、より短い通電時間で対向電極3の表面温度を上昇させることができ、対向電極3に堆積した油を短時間で融解させて除去することが可能となる。   Therefore, the surface temperature of the counter electrode 3 can be raised in a shorter energization time, and the oil deposited on the counter electrode 3 can be melted and removed in a short time.

なお、対向電極3の材質としては、表面抵抗率を106〜1010Ω/□とすることができればよい。たとえば、セラミック製の絶縁性基板の表面に半導電性の被覆を備えたものであってもよい。半導電性被覆は、絶縁性基板の表面にスクリーン印刷により半導電インクを塗布し、乾燥、焼成することで作成することができる。半導電インクは、酸化スズなどの導電剤とガラス粉などの接着剤を含み、前記成分を溶剤に混合あるいは溶解させたものである。 In addition, as a material of the counter electrode 3, it is only necessary that the surface resistivity can be 10 6 to 10 10 Ω / □. For example, the surface of a ceramic insulating substrate may be provided with a semiconductive coating. The semiconductive coating can be prepared by applying a semiconductive ink to the surface of the insulating substrate by screen printing, drying and baking. The semiconductive ink contains a conductive agent such as tin oxide and an adhesive such as glass powder, and the above components are mixed or dissolved in a solvent.

導電剤粒子としては、酸化スズが酸化に対する安定性と入手の容易さの理由で好ましく、他にはZnO、PbO2,CdO,In23、Tl23、Ga23、Fe34などの酸化物導電材およびこれらの複合酸化物などが使用可能である。導電剤としての酸化スズ(SnO2)にSbなどをドープしたものを用いてもよい。接着剤は、導電剤粒子と、絶縁性基板16とを接着できればよい。 As the conductive agent particles, tin oxide is preferable because of its stability to oxidation and easy availability. Besides, ZnO, PbO 2 , CdO, In 2 O 3 , Tl 2 O 3 , Ga 2 O 3 , Fe 3 Oxide conductive materials such as O 4 and composite oxides thereof can be used. Tin oxide (SnO 2) as a conductive agent may be used as doped and Sb. The adhesive only needs to adhere the conductive agent particles and the insulating substrate 16.

接着剤としてガラス粉やコロイダルシリカ、シリケート化合物、チタネート化合物などを用いてもよい。ガラス粉は化学的に不活性で耐酸化性があり、好ましい。アルミナやジルコニア、チタニアの粉末あるいはフッ素樹脂粒子などを用いてもよい。接着剤の大きさは、形状を安定化させるために導電材粒子よりも大きいほうが好ましく、導電材の2〜100倍程度の大きさにすると良い。   As an adhesive, glass powder, colloidal silica, silicate compound, titanate compound, or the like may be used. Glass powder is preferably chemically inert and oxidation resistant. Alumina, zirconia, titania powder or fluororesin particles may be used. The size of the adhesive is preferably larger than the conductive material particles in order to stabilize the shape, and is preferably about 2 to 100 times the size of the conductive material.

本発明の実施の形態では、対向電極3の表面に、油分解促進触媒を添着させた。油分解促進触媒としては、白金担持アルミナを用いている。   In the embodiment of the present invention, an oil decomposition promoting catalyst is added to the surface of the counter electrode 3. Platinum-supported alumina is used as the oil decomposition promoting catalyst.

これにより、対向電極3に通電して発熱させた際に、付着した油を融解させるだけではなく、付着した油の熱分解を促進することができ、対向電極3に堆積した油を融解させるだけでなく、合わせて油の分解も行い、油の除去を短時間で行うことが可能となる。   Thereby, when the counter electrode 3 is energized to generate heat, not only the adhered oil is melted, but also the thermal decomposition of the adhered oil can be promoted, and only the oil deposited on the counter electrode 3 is melted. In addition, the oil can be decomposed and the oil can be removed in a short time.

図1に示すように、油煙浄化デバイス1は、放電電極2への電圧印加と、高圧電極4への電圧印加とを切り替える電圧印加切替手段6を備えている。   As shown in FIG. 1, the oil smoke purification device 1 includes voltage application switching means 6 that switches between voltage application to the discharge electrode 2 and voltage application to the high-voltage electrode 4.

放電電極2と高圧電極4への電圧印加を同時に行った場合、放電電極2と高圧電極4の距離が近い箇所で電界の干渉が生じ、放電電極2の一部から放電が生じなくなり、集油性能が低下する可能性がある。   When voltage is simultaneously applied to the discharge electrode 2 and the high voltage electrode 4, electric field interference occurs at a location where the distance between the discharge electrode 2 and the high voltage electrode 4 is short, and no discharge occurs from a part of the discharge electrode 2, thereby collecting oil. Performance may be degraded.

放電電極2への電圧印加と、高圧電極4への電圧印加とを切り替える電圧印加切替手段6を設けることにより、油煙浄化デバイス1を運転しているときは放電電極2に電圧を印加して集油し、油煙浄化デバイス1を停止してメンテナンスモード等になったときは高圧電極4に電圧を印加してアース電極5との電位差を与え、対向電極3を発熱させて対向電極3に堆積した油を融解させて除去することで、集油性能の維持と高いメンテナンス性の確保を両立することができる。   By providing voltage application switching means 6 for switching between voltage application to the discharge electrode 2 and voltage application to the high-voltage electrode 4, when the oil purification device 1 is operating, voltage is applied to the discharge electrode 2 to collect the voltage. When the oil smoke purification device 1 is stopped and the maintenance mode or the like is entered, a voltage is applied to the high voltage electrode 4 to give a potential difference from the ground electrode 5, the counter electrode 3 is heated and deposited on the counter electrode 3. By melting and removing the oil, it is possible to maintain both oil collecting performance and secure high maintainability.

図1に示すように、油煙浄化デバイス1は、対向電極3の表面温度を検出する温度検知手段7を備えている。そして、温度検知手段7で検知した対向電極3の表面温度が100度を超えようとした場合に、高圧電極4への印加電圧を制限または停止するように制御されている。温度検知手段7としては、赤外線センサーを使用している。   As shown in FIG. 1, the oil smoke purification device 1 includes a temperature detection means 7 that detects the surface temperature of the counter electrode 3. And when the surface temperature of the counter electrode 3 detected by the temperature detection means 7 is going to exceed 100 degree | times, it is controlled so that the applied voltage to the high voltage electrode 4 may be restrict | limited or stopped. An infrared sensor is used as the temperature detecting means 7.

表面が半導電性の対向電極3に電流を流し続けた場合に、対向電極3の温度が必要以上に高くなりすぎる恐れがある。多くの油は100度以下で溶けて粘度が低下して、除去しやすくなる。対向電極3の表面温度を検出する温度検知手段7を備え、対向電極3の表面温度が100度を超えようとした場合に、高圧電極4への印加電圧を制限または停止して表面温度の上昇を防止することにより、安全性とメンテナンス性の確保を両立することができる。   If a current continues to flow through the counter electrode 3 whose surface is semiconductive, the temperature of the counter electrode 3 may become excessively high. Many oils dissolve at less than 100 degrees, reduce viscosity, and are easy to remove. A temperature detecting means 7 for detecting the surface temperature of the counter electrode 3 is provided, and when the surface temperature of the counter electrode 3 is about 100 degrees, the voltage applied to the high voltage electrode 4 is limited or stopped to increase the surface temperature. By preventing this, both safety and maintainability can be ensured.

なお、本実施の形態では放電電極2の材質をステンレスとしたが、他の材料として、タングステン、チタン、Ni−Cr合金などを用いてもよい。放電可能であれば、炭素・スズ・SiCなどを含む材質を用いてもよい。   Although the discharge electrode 2 is made of stainless steel in the present embodiment, tungsten, titanium, Ni—Cr alloy or the like may be used as another material. As long as discharge is possible, a material containing carbon, tin, SiC, or the like may be used.

なお、本実施の形態では対向電極3の表面に、油分解促進触媒として白金担持アルミナを添着したが、これに限定されるものではなく、油分解を促進する性能を有する触媒であればよい。   In the present embodiment, platinum-supported alumina is attached to the surface of the counter electrode 3 as an oil decomposition accelerating catalyst. However, the present invention is not limited to this, and any catalyst having the ability to promote oil decomposition may be used.

なお、本実施の形態では温度検知手段7として赤外線センサーを用いたが、これに限定されるものではなく、対向電極3の表面温度を検知できる手段であればよい。   In the present embodiment, an infrared sensor is used as the temperature detection means 7, but the present invention is not limited to this, and any means that can detect the surface temperature of the counter electrode 3 may be used.

なお、本実施の形態の油煙浄化デバイス1の空気流れ上流側に、高電圧を印加する荷電電極と、アースに接続する接地電極とを交互に積層した集油ユニットを設けてもよい。これにより、さらに集油性能を高めた油煙浄化デバイス1を提供することができる。   In addition, you may provide the oil collection unit which laminated | stacked alternately the charging electrode which applies a high voltage, and the ground electrode connected to earth | ground at the air flow upstream of the oil smoke purification device 1 of this Embodiment. Thereby, the oil smoke purification device 1 which further improved oil collection performance can be provided.
