特開２０１０−１３１５１５号公報JP 2010-131515 A

このような従来の電気集塵装置においては、オゾンの発生自体を停止するものではなく、オゾンの濃度は電気集塵装置内の通風量に依存するため、何らかの原因により通風量が低下した場合は筐体内にオゾンが充満し、筐体内のオゾン濃度が上昇するという課題が残る。   In such a conventional electrostatic precipitator, the generation of ozone itself is not stopped, and the concentration of ozone depends on the amount of ventilation in the electrostatic precipitator. The problem remains that the housing is filled with ozone and the ozone concentration in the housing increases.

そこで本発明は、上記従来の課題を解決するものであり、筐体内の風量が低下した場合に、筐体内のオゾン濃度の上昇を抑制する電機集塵装置を提供することを目的とする。   Therefore, the present invention solves the above-described conventional problems, and an object of the present invention is to provide an electrical dust collector that suppresses an increase in ozone concentration in the housing when the air volume in the housing is reduced.

そして、この目的を達成するために、本発明に係る電気集塵装置は、筐体と、前記筐体内に設けられた帯電部および集塵部とを備え、前記筐体の吸込口から吸込まれた空気は前記筐体内を通過して前記筐体の吹出口から吹き出される電気集塵装置であって、前記筐体内の風量を検知するための検知装置を備え、前記検知装置は、回転軸と、通風抵抗部と、回転部と、センサーとからなり、前記回転軸は前記筐体内において前記集塵部よりも下流側に設けられ、前記通風抵抗部は、前記回転軸に固定され、風が無い場合は自重で下がり、風がある場合は風圧により回動し、前記回転部は、前記通風抵抗部よりも前記筐体の内壁側において、前記回転軸に固定され、前記センサーは、前記回転部と前記センサーとの距離を検知し、前記距離に応じて前記帯電部と前記集塵部の通電のオンとオフが切り替わるとしたものであり、これにより所期の目的を達成するものである。   In order to achieve this object, an electrostatic precipitator according to the present invention includes a housing, a charging unit and a dust collecting unit provided in the housing, and is sucked from a suction port of the housing. The air is an electrostatic precipitator that passes through the casing and is blown out from the outlet of the casing, and includes a detecting device for detecting the air volume in the casing, and the detecting device has a rotating shaft.

本発明に係る電気集塵装置は、筐体と、前記筐体内に設けられた帯電部および集塵部とを備え、前記筐体の吸込口から吸込まれた空気は前記筐体内を通過して前記筐体の吹出口から吹き出される電気集塵装置であって、前記筐体内の風量を検知するための検知装置を備え、前記検知装置は、回転軸と、通風抵抗部と、回転部と、センサーとからなり、前記回転軸は前記筐体内において前記集塵部よりも下流側に設けられ、前記通風抵抗部は、前記回転軸に固定され、風が無い場合は自重で下がり、風がある場合は風圧により回動し、前記回転部は、前記通風抵抗部よりも前記筐体の内壁側において、前記回転軸に固定され、前記センサーは、前記回転部と前記センサーとの距離を検知し、前記距離に応じて前記帯電部と前記集塵部の通電のオンとオフが切り替わるという構成を有する。   An electric dust collector according to the present invention includes a housing, a charging unit and a dust collecting unit provided in the housing, and air sucked from a suction port of the housing passes through the housing. An electrostatic precipitator that is blown out from an air outlet of the housing, comprising a detection device for detecting an air volume in the housing, the detection device comprising: a rotation shaft, a ventilation resistance portion, a rotation portion, The rotation shaft is provided downstream of the dust collection portion in the housing, and the ventilation resistance portion is fixed to the rotation shaft, and falls in its own weight when there is no wind. In some cases, the rotating portion is rotated by wind pressure, the rotating portion is fixed to the rotating shaft on the inner wall side of the housing with respect to the ventilation resistance portion, and the sensor detects a distance between the rotating portion and the sensor. The electrification unit and the dust collection unit are energized according to the distance. Has a configuration that is turned off is switched.

これにより、前記センサーが、前記回転部との距離を検知し、前記距離に応じて前記帯電部と前記集塵部の通電を停止するので、通風が無いあるいは少ないことによる筐体内のオゾン濃度の上昇を抑制するという効果を奏する。   As a result, the sensor detects the distance to the rotating part and stops energization of the charging part and the dust collecting part according to the distance. There is an effect of suppressing the rise.

また、前記回転部に磁石を設け、前記センサーは、前記磁石による磁力を検知することにより、前記距離を検知するという構成にしてもよい。   Further, a magnet may be provided in the rotating part, and the sensor may detect the distance by detecting a magnetic force by the magnet.

これにより、前記センサーが、前記回転部との距離を検知し、前記距離に応じて前記帯電部と前記集塵部の通電を停止するので、比較的簡易な構成で、通風が無いあるいは少ないことによる筐体内のオゾン濃度の上昇を抑制するという効果を奏する。   As a result, the sensor detects the distance to the rotating part and stops energization of the charging part and the dust collecting part according to the distance, so that there is no or little ventilation with a relatively simple configuration. There is an effect of suppressing an increase in ozone concentration in the casing.

また、前記回転軸は、前記筐体内高さの中点において水平に設けられ、前記磁石を２つ、前記回転軸を中心に点対称となるように前記回転部に設け、前記通風抵抗部は前記回転軸を軸として３６０度回動可能であるという構成にしてもよい。   The rotating shaft is provided horizontally at the midpoint of the height in the housing, the two magnets are provided in the rotating portion so as to be symmetric about the rotating shaft, and the ventilation resistance portion is You may make it the structure which can be rotated 360 degree | times centering on the said rotating shaft.

これにより、電気集塵装置の天地を反転して使用しても、どちらか一方の磁石がセンサーと接近し、筐体内の通風を検知するので、電気集塵装置の天地の制限なく使用できるという効果を奏する。   As a result, even if the top and bottom of the electrostatic precipitator is reversed, one of the magnets approaches the sensor and detects ventilation in the housing, so it can be used without any restrictions on the top of the electrostatic precipitator. There is an effect.

また、前記回転部は、前記回転軸の軸方向に直交する棒状としてもよい。   Moreover, the said rotation part is good also as a rod shape orthogonal to the axial direction of the said rotating shaft.

これにより、前記センサーの検出範囲をより狭い範囲に限定できるので、通風の検知精度をさらに高めることができる。   Thereby, since the detection range of the sensor can be limited to a narrower range, it is possible to further improve the accuracy of detecting ventilation.

また、前記センサーは、前記筐体内において通風が無い場合に、前記通風抵抗部が自重で下がった位置において、前記磁石と最接近する位置に設けた構成としてもよい。   The sensor may be provided at a position closest to the magnet in a position where the ventilation resistance portion is lowered by its own weight when there is no ventilation in the housing.

これにより、通風が低下して前記通風抵抗部が自重で下がり、前記通風抵抗部の傾きがゼロ又は傾きが小さくなった場合に前記センサーが磁力を検出して前記帯電部と前記集塵部の通電をオフする。逆に、前記通風抵抗部を傾けるだけの通風が存在するときに前記センサーが磁力を検出しなくなり、前記帯電部と前記集塵部の通電をオンする。このように、前記検知装置により通風が低下したかどうかが検知しやすくなり、前記帯電部と前記集塵部の通電のオン・オフをさらに効果的に行うことができる。   As a result, ventilation decreases and the ventilation resistance part falls by its own weight, and when the inclination of the ventilation resistance part is zero or the inclination becomes small, the sensor detects the magnetic force, and the charging part and the dust collection part Turn off the power. On the other hand, when there is ventilation enough to incline the ventilation resistance part, the sensor stops detecting the magnetic force, and energization of the charging part and the dust collecting part is turned on. In this way, it is easy to detect whether or not ventilation has been reduced by the detection device, and energization of the charging unit and the dust collection unit can be more effectively performed.

また、前記回転軸および前記回転部は導電性材料からなり、前記回転軸および前記回転部に対して、前記帯電部あるいは前記集塵部に印加する電圧の一部を印加し、前記センサーは前記回転部から発生する電場を検知するという構成にしてもよい。   Further, the rotating shaft and the rotating portion are made of a conductive material, and a part of the voltage applied to the charging portion or the dust collecting portion is applied to the rotating shaft and the rotating portion, and the sensor You may make it the structure of detecting the electric field which generate | occur | produces from a rotation part.

これにより、前記センサーが電場を検知することにより前記回転部との距離を検知することが可能なので、磁石などの部品点数を増やすことなく検知装置を構成できるという効果を奏する。   Thereby, since the sensor can detect the distance from the rotating part by detecting the electric field, the detection device can be configured without increasing the number of parts such as magnets.

また、前記回転部は、前記回転軸の軸方向に直交する棒状であり、前記センサーは、前記筐体内において風が無い場合に、前記通風抵抗部が自重で下がった位置において、前記回転部と最接近する位置に設けられた構成としてもよい。   Further, the rotating part is in a rod shape orthogonal to the axial direction of the rotating shaft, and the sensor is located at a position where the ventilation resistance part is lowered by its own weight when there is no wind in the casing. It is good also as a structure provided in the position which approaches most.

これにより、通風が低下して前記通風抵抗部が自重で下がり、前記通風抵抗部の傾きがゼロ又は傾きが小さくなった場合に前記センサーが電場を検出して前記帯電部と前記集塵部の通電をオフする。逆に、前記通風抵抗部を傾けるだけの通風が存在するときに前記センサーが電場を検出しなくなり、前記帯電部と前記集塵部の通電をオンする。このように、前記検知装置により通風が低下したかどうかが検知しやすくなり、前記帯電部と前記集塵部の通電のオン・オフをさらに効果的に行うことができる。   As a result, ventilation decreases and the ventilation resistance portion falls by its own weight, and when the inclination of the ventilation resistance portion is zero or the inclination becomes small, the sensor detects an electric field and detects the charging portion and the dust collection portion. Turn off the power. On the other hand, when there is ventilation enough to incline the ventilation resistance section, the sensor no longer detects an electric field, and energization of the charging section and the dust collection section is turned on. In this way, it is easy to detect whether or not ventilation has been reduced by the detection device, and energization of the charging unit and the dust collection unit can be more effectively performed.

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は本発明に係る電気集塵装置の平面図である。また、図２は図１に対する正面図である。 (Embodiment 1)
FIG. 1 is a plan view of an electrostatic precipitator according to the present invention. FIG. 2 is a front view with respect to FIG.

図１または図２に示すように、電気集塵装置は、筐体１に帯電部２と集塵部３と吸込口２０と吹出口２１を備える。筐体１の内部に通風を与える送風機４は筐体１の例えば吹出口２１に接続される。   As shown in FIG. 1 or FIG. 2, the electrostatic precipitator includes a charging unit 2, a dust collecting unit 3, a suction port 20, and a blower port 21 in a housing 1. The blower 4 that gives ventilation to the inside of the housing 1 is connected to, for example, the air outlet 21 of the housing 1.

送風機４の運転により、吸込口２０から吸込まれた空気は筐体１の内部を通過して吹出口２１から吹き出される。   By the operation of the blower 4, the air sucked from the suction port 20 passes through the inside of the housing 1 and is blown out from the air outlet 21.

吸込口２０から吸込まれた空気に対して、帯電部２はコロナ放電を発生して塵埃に電荷を与える。集塵部３は、電荷を帯びた塵埃を吸着することで集塵を行う。   The charging unit 2 generates corona discharge with respect to the air sucked from the suction port 20 to give a charge to the dust. The dust collecting unit 3 collects dust by adsorbing charged dust.

筐体１の内部には、筐体１の内部の通風を検知するための検知装置１０を備え、検知装置１０は、回転軸５と、通風抵抗部６と、回転部７と、センサー９とからなる。   Inside the housing 1 is provided with a detection device 10 for detecting the ventilation inside the housing 1, and the detection device 10 includes a rotation shaft 5, a ventilation resistance portion 6, a rotation portion 7, and a sensor 9. Consists of.

回転軸５は例えば通風抵抗部６の回動の中心となる棒である。   The rotating shaft 5 is, for example, a rod that is the center of rotation of the ventilation resistance unit 6.

通風抵抗部６は、回転軸５に固定され、風が無い場合は自重で下がり、風がある場合は風圧により回動する。   The ventilation resistance unit 6 is fixed to the rotating shaft 5 and is lowered by its own weight when there is no wind, and is rotated by wind pressure when there is wind.

回転部７は、通風抵抗部６よりも筐体１の内壁側において回転軸５に固定され、通風抵抗部６が風圧により回動することで、回転部７も同時に回動する。   The rotating unit 7 is fixed to the rotating shaft 5 on the inner wall side of the housing 1 with respect to the ventilation resistance unit 6, and the rotation unit 7 is also rotated at the same time as the ventilation resistance unit 6 is rotated by the wind pressure.

センサー９は、回転部７とセンサー９との距離を検知し、制御部２２によって距離に応じて帯電部２と集塵部３の通電のオンとオフが切り替わる。   The sensor 9 detects the distance between the rotating unit 7 and the sensor 9, and the control unit 22 switches on and off the energization of the charging unit 2 and the dust collecting unit 3 according to the distance.

このような構成によれば、筐体１内の通風が低下して通風抵抗部６が自重で下がり、通風抵抗部６の鉛直方向に対する傾きがゼロ又は小さくなった場合にセンサー９が回転部７を検出して帯電部２と集塵部３の通電をオフするため、通風の低下による筐体１内のオゾン濃度の上昇を抑制する効果がある。   According to such a configuration, when the ventilation in the housing 1 is reduced and the ventilation resistance unit 6 is lowered by its own weight, and the inclination of the ventilation resistance unit 6 with respect to the vertical direction is zero or small, the sensor 9 is rotated by the rotation unit 7. Is detected and the energization of the charging unit 2 and the dust collecting unit 3 is turned off. Therefore, there is an effect of suppressing an increase in ozone concentration in the housing 1 due to a decrease in ventilation.

なお、回転部７に磁石８を設け、センサー９は、磁石８による磁力を検知することにより、距離を検知する構成としてもよい。   In addition, it is good also as a structure which provides the magnet 8 in the rotation part 7, and the sensor 9 detects a distance by detecting the magnetic force by the magnet 8. FIG.

また、センサー９の設置位置は、回転部７の可動域であれば任意であるが、例えば筐体１内において風が無い場合に、通風抵抗部６が自重で下がった位置において、磁石８と最接近する位置に設けることにより、通風が低下したかどうかが検知しやすくなり、帯電部と集塵部３の通電のオン・オフをさらに効果的に行うことができる。   The installation position of the sensor 9 is arbitrary as long as it is within the movable range of the rotating unit 7. For example, when there is no wind in the housing 1, the position where the ventilation resistance unit 6 is lowered by its own weight and the magnet 8. By providing at the closest position, it becomes easy to detect whether or not the ventilation is lowered, and the electrification of the charging unit and the dust collecting unit 3 can be more effectively turned on / off.

また、回転部７は回転軸５の軸方向に直交する棒状としてもよい。これにより、センサー９の検出範囲をより狭い範囲に限定できる。   The rotating unit 7 may have a rod shape orthogonal to the axial direction of the rotating shaft 5. Thereby, the detection range of the sensor 9 can be limited to a narrower range.

次に、図３は検知装置１０の通風状態における斜視図であり、図４は検知装置１０の無風状態における斜視図である。図３および図４においては、図１または図２と同様の構成要素については同一の符号を付し、その詳細な説明は省略する。   Next, FIG. 3 is a perspective view of the detection device 10 in a ventilation state, and FIG. 4 is a perspective view of the detection device 10 in a no-air state. 3 and 4, the same components as those in FIG. 1 or 2 are denoted by the same reference numerals, and detailed description thereof is omitted.

このような構成によれば、送風機４によって筐体１の内部に通風が行われた場合、通風抵抗部６が風圧を受けて回転軸５を軸に回動し、同時に回転部７が連なって回動するため、回転部７とセンサー９との距離が大きくなり、制御部２２がそれを検知して帯電部２と集塵部３の通電をオンにする。また、筐体１の内部に通風が行われていない場合、通風抵抗部６は回転軸５を軸に自重で回動して下がり、同時に回転部７が連なって回動するため、回転部７とセンサー９との距離が小さくなり、制御部２２がそれを検知して帯電部２と集塵部３の通電をオフにする。このため、筐体１の内部の通風を検知し、通風量に応じた帯電部２と集塵部３の通電のオンとオフの切り替えが可能となる。   According to such a configuration, when ventilation is performed inside the housing 1 by the blower 4, the ventilation resistance unit 6 receives the wind pressure and rotates about the rotation shaft 5, and at the same time the rotation unit 7 continues. Since it rotates, the distance between the rotating unit 7 and the sensor 9 increases, and the control unit 22 detects this and turns on the energization of the charging unit 2 and the dust collecting unit 3. Further, when ventilation is not performed inside the housing 1, the ventilation resistance unit 6 is rotated by its own weight about the rotation shaft 5 and is lowered and simultaneously the rotation unit 7 is rotated. The distance between the sensor 9 and the sensor 9 is reduced, and the control unit 22 detects this and turns off the energization of the charging unit 2 and the dust collecting unit 3. For this reason, ventilation inside the housing 1 is detected, and it is possible to switch on and off the energization of the charging unit 2 and the dust collecting unit 3 according to the amount of ventilation.

図５は、筐体１内の通風が低下したかどうかによって帯電部２と集塵部３の通電のオンとオフを切り替える流れを示したブロック図である。   FIG. 5 is a block diagram showing a flow for switching on and off the energization of the charging unit 2 and the dust collecting unit 3 depending on whether or not the ventilation in the housing 1 is lowered.

図５を用いて、本実施形態の電気集塵機の動作を説明する。   The operation of the electrostatic precipitator according to this embodiment will be described with reference to FIG.

まず、電気集塵装置が停止し、送風機４が運転した状態であり、筐体１の内部に通風があることを確認した上で、電気集塵装置を運転する。検知装置１０によって、筐体１の内部に十分な通風があることが確認される場合は、帯電部２と集塵部３への通電をオンのまま継続する。検知装置１０によって、筐体１の内部に十分な通風がないことが確認される場合は、帯電部２と集塵部３への通電をオフする。その後、再度、筐体１の内部に通風があることを確認した上で、電気集塵装置を運転する。   First, the electrostatic precipitator is stopped and the blower 4 is in operation, and after confirming that there is ventilation inside the housing 1, the electrostatic precipitator is operated. When the detection device 10 confirms that there is sufficient ventilation inside the housing 1, energization of the charging unit 2 and the dust collecting unit 3 is continued while being on. When the detection device 10 confirms that there is not sufficient ventilation inside the housing 1, the energization to the charging unit 2 and the dust collecting unit 3 is turned off. Then, after confirming that there is ventilation inside the housing 1 again, the electrostatic precipitator is operated.

なお、図１または図２では、送風機４は筐体１よりも下流に接続されるが、筐体１の上流、あるいは筐体１の内部に設置した構成としてもよい。   In FIG. 1 or FIG. 2, the blower 4 is connected downstream of the housing 1, but may be configured upstream of the housing 1 or inside the housing 1.

また、回転軸５は筐体１内において集塵部３よりも下流側に設けることが好ましい。この構成によれば、筐体１内に流入する空気中に含まれる塵埃が帯電部２および集塵部３によって吸着されることにより、比較的清浄な環境下で検知装置１０が動作できるため、検知装置１０への塵埃の堆積を抑えることができる。   Moreover, it is preferable that the rotating shaft 5 is provided in the housing 1 on the downstream side of the dust collecting unit 3. According to this configuration, since the dust contained in the air flowing into the housing 1 is adsorbed by the charging unit 2 and the dust collecting unit 3, the detection device 10 can operate in a relatively clean environment. Accumulation of dust on the detection device 10 can be suppressed.

また、回転軸５が水平である場合、通風抵抗部６の荷重に軸方向成分が発生せず、通風抵抗部６が自重でスムーズに下がることとなるため、回転軸５は水平であることが好ましい。また、回転軸５が空気の流れに直交する場合、通風抵抗部６が通風によって受ける風圧に軸方向成分が発生せず、通風抵抗部６の風圧による可動の妨げとならないため、回転軸５は空気の流れに直交することが好ましい。ここで、水平とは完全な水平だけでなく、数度傾いた略水平も含む。また、直交とは完全な直交だけでなく、数度傾いた略直交も含む。   In addition, when the rotating shaft 5 is horizontal, no axial component is generated in the load of the ventilation resistance portion 6 and the ventilation resistance portion 6 is smoothly lowered by its own weight. Therefore, the rotation shaft 5 may be horizontal. preferable. In addition, when the rotation shaft 5 is orthogonal to the air flow, no axial component is generated in the wind pressure received by the ventilation resistance portion 6 due to the ventilation, and movement of the ventilation resistance portion 6 due to the wind pressure is not hindered. It is preferable to be orthogonal to the air flow. Here, “horizontal” includes not only perfect horizontal but also substantially horizontal inclined several degrees. Further, the term “orthogonal” includes not only perfect orthogonality but also substantially orthogonality inclined several degrees.

また、本実施例では制御部２２を筐体１に設けたが、制御部２２は筐体１に設けなくても良い。例えば、筐体１には制御部２２を設けずに、遠隔地にある制御部２２によって、帯電部２と集塵部３の通電のオンとオフを切り替える制御もあり得る。   In the present embodiment, the control unit 22 is provided in the housing 1, but the control unit 22 may not be provided in the housing 1. For example, the control unit 22 is not provided in the housing 1, and the control unit 22 in a remote place may be controlled to switch on / off the energization of the charging unit 2 and the dust collection unit 3.

また、図３、図４に示すように、例えば回転軸５は、筐体１内高さの中点において水平に設けられ、磁石８を２つ、回転軸５を中心に点対称となるように回転部７に設け、通風抵抗部６は回転軸５を軸として３６０度回動可能とすることで、天地の制限がなく使用できる。ここで、水平とは完全な水平だけでなく、数度傾いた略水平も含む。また、直交とは完全な直交だけでなく、数度傾いた略直交も含む。   As shown in FIGS. 3 and 4, for example, the rotating shaft 5 is provided horizontally at the midpoint of the height inside the housing 1, and is symmetrical with respect to the two magnets 8 and the rotating shaft 5. The ventilation resistance unit 6 is provided in the rotation unit 7 and can be rotated 360 degrees about the rotation shaft 5 so that it can be used without any limitation. Here, “horizontal” includes not only perfect horizontal but also substantially horizontal inclined several degrees. Further, the term “orthogonal” includes not only perfect orthogonality but also substantially orthogonality inclined several degrees.

また、回転軸５および回転部７は金属などの導電性材料からなり、回転軸５および回転部７に対して、帯電部２あるいは集塵部３に印加する電圧の一部を印加し、センサー９は回転部７から発生する電場を検知するという構成にしてもよい。   The rotating shaft 5 and the rotating portion 7 are made of a conductive material such as a metal, and a part of the voltage applied to the charging portion 2 or the dust collecting portion 3 is applied to the rotating shaft 5 and the rotating portion 7 to thereby detect the sensor. 9 may be configured to detect an electric field generated from the rotating unit 7.

これにより、センサー９が電場を検知することにより回転部７との距離を検知することが可能なので、磁石などの部品点数を増やすことなく検知装置１０を構成できる。   Thereby, since the sensor 9 can detect the distance from the rotating unit 7 by detecting the electric field, the detection device 10 can be configured without increasing the number of components such as magnets.

また、回転部７は、回転軸５の軸方向に直交する棒状であり、センサー９は、筐体１内において風が無い場合に、通風抵抗部６が自重で下がった位置において、回転部７と最接近する位置に設けられた構成としてもよい。   The rotating unit 7 has a rod shape orthogonal to the axial direction of the rotating shaft 5, and the sensor 9 has a rotating unit 7 at a position where the ventilation resistance unit 6 is lowered by its own weight when there is no wind in the housing 1. It is good also as a structure provided in the position closest to.

これにより、通風が低下して通風抵抗部６が自重で下がり、通風抵抗部６の傾きがゼロ又は傾きが小さくなった場合にセンサー９が電場を検出して帯電部２と集塵部３の通電をオフする。逆に、通風抵抗部６を傾けるだけの通風が存在するときにセンサー９が電場を検出しなくなり、帯電部２と集塵部３の通電をオンする。このように、検知装置１０により通風が低下したかどうかが検知しやすくなり、帯電部２と集塵部３の通電のオン・オフをさらに効果的に行うことができる。   As a result, the ventilation is reduced, the ventilation resistance unit 6 is lowered by its own weight, and when the inclination of the ventilation resistance unit 6 is zero or the inclination is small, the sensor 9 detects the electric field and the charging unit 2 and the dust collection unit 3 Turn off the power. On the other hand, when there is ventilation enough to tilt the ventilation resistance section 6, the sensor 9 does not detect the electric field, and the energization of the charging section 2 and the dust collection section 3 is turned on. Thus, it becomes easy to detect whether or not the ventilation has been lowered by the detection device 10, and energization of the charging unit 2 and the dust collection unit 3 can be more effectively turned on / off.

本発明に係る電気集塵装置は、筐体内のオゾン濃度の上昇を抑制する電気集塵装置等として有用である。   The electrostatic precipitator according to the present invention is useful as an electrostatic precipitator that suppresses an increase in the ozone concentration in the housing.
