Description

フィルタユニット及びそれを備えた車両用空気調和装置Filter unit and vehicle air conditioner including the same
　本発明は、空気中の塵挨を捕集するフィルタユニット及びそれを備えた車両用空気調和装置に関する。 The present invention relates to a filter unit that collects dust in the air and a vehicle air conditioner including the same.
　従来のフィルタユニット及びそれを備えた車両用空気調和装置は特許文献１に開示されている。図１５はこの車両用空気調和装置の概略構成を示す側面断面図である。車両用空気調和装置２は、人が乗る車室とエンジンが収容されるエンジンルームとの間の機器室内に配置されている。 A conventional filter unit and a vehicle air conditioner including the filter unit are disclosed in Patent Document 1. FIG. 15 is a side sectional view showing a schematic configuration of the vehicle air conditioner. The vehicle air conditioner 2 is disposed in an equipment room between a passenger compartment in which a person rides and an engine room in which an engine is accommodated.
　車両用空気調和装置２はハウジング１０を有し、ハウジング１０には吸込口１１と吹出口１２とが開口している。吸込口１１は車外の空気（外気ＯＡ）を吸い込む外気吸込口１１ａと車室内の空気（内気ＩＡ）を吸い込む内気吸込口１１ｂとから成る。吹出口１２は車室内に調和空気ＣＡを吹き出す。ハウジング１０内には、外気吸込口１１ａ及び内気吸込口１１ｂと吹出口１２とを連通させる送風経路１３が設けられている。 The vehicle air conditioner 2 has a housing 10, and a suction port 11 and an outlet 12 are opened in the housing 10. The suction port 11 includes an outside air suction port 11a for sucking air outside the vehicle (outside air OA) and an inside air suction port 11b for sucking air inside the vehicle (inside air IA). The air outlet 12 blows out conditioned air CA into the vehicle interior. Inside the housing 10, an outside air suction port 11 a, an inside air suction port 11 b and a blower passage 13 that communicates with the air outlet 12 are provided.
　送風経路１３内には外気吸込口１１ａ及び内気吸込口１１ｂから吹出口１２に向かって、切換ダンパ３１、フィルタユニット１４、送風機１５、イオン発生装置１８（除菌部）、蒸発器１６、ヒーターコア１７が順に配されている。切換ダンパ３１によって外気・内気の吸込みが切り替えられる。送風機１５の駆動によって外気吸込口１１ａ及び内気吸込口１１ｂの一方から空気が送風経路１３内に吸い込まれる。空気に含まれる塵挨や花粉等の浮遊微粒子はフィルタユニット１４のフィルタ１４ａによって除去される。塵挨等が除去された空気は蒸発器１６で冷却された後に吹出口１２から車室内に送出される。または、ヒーターコア１７によって加熱された後に吹出口１２から車室内に送出される。これにより、車室内の空気が調和される。 In the ventilation path 13, the switching damper 31, the filter unit 14, the blower 15, the ion generator 18 (sanitization unit), the evaporator 16, and the heater core are directed from the outside air inlet 11 a and the inside air inlet 11 b toward the outlet 12. 17 are arranged in order. The switching damper 31 switches between the intake of outside air and inside air. By driving the blower 15, air is sucked into the blower path 13 from one of the outside air inlet 11 a and the inside air inlet 11 b. Airborne particles such as dust and pollen contained in the air are removed by the filter 14 a of the filter unit 14. The air from which dust and the like have been removed is cooled by the evaporator 16 and then sent out from the air outlet 12 into the vehicle interior. Alternatively, after being heated by the heater core 17, it is sent out from the air outlet 12 into the vehicle interior. Thereby, the air in the passenger compartment is harmonized.
　このとき、イオン発生装置１８によって発生したイオンやオゾンが送風経路１３を流通する空気に含まれる。これにより、結露水によって特に細菌等が増殖しやすい蒸発器１６及び蒸発器１６の周辺部材等を除菌できるとともに車室内を除菌できる。 At this time, ions and ozone generated by the ion generator 18 are included in the air flowing through the air blowing path 13. Thereby, it is possible to sterilize the evaporator 16 and the peripheral members of the evaporator 16 in which bacteria and the like are particularly prone to grow due to the dew condensation water, and also sterilize the vehicle interior.

　しかしながら、上記従来の構成では、イオン発生装置１８は特定の車種の車両用空気調和装置２にのみ設置されており、全車種の車両用空気調和装置２に設置されているわけではない。ここで、特定車種以外の車種にも追加オプションとして車両用空気調和装置２にイオン発生装置１８を取り付けることはできる。しかしながら、イオン発生装置１８は送風経路１３内の送風機１５と蒸発器１６との間の位置に設けられ、使用者の手が届きにくい位置に配置される。このため、使用者自身が行うのは困難であり、送風経路１３内部に配されるイオン発生装置１８は自動車メーカーやその販売代理店により取り付け作業が行われる。 However, in the above-described conventional configuration, the ion generator 18 is installed only in the vehicle air conditioner 2 of a specific vehicle type, and is not installed in the vehicle air conditioner 2 of all vehicle types. Here, the ion generator 18 can be attached to the vehicle air conditioner 2 as an additional option for vehicle types other than the specific vehicle type. However, the ion generator 18 is provided at a position between the blower 15 and the evaporator 16 in the blowing path 13 and is disposed at a position that is difficult for the user to reach. For this reason, it is difficult for the user himself to perform, and the ion generator 18 disposed in the air blowing path 13 is installed by an automobile manufacturer or its sales agent.
　また、使用者自身でイオン発生装置１８のメンテナンスや交換を容易に行うことができないという問題もあった。 There is also a problem that the user cannot easily maintain and replace the ion generator 18.
　本発明は、空気を除菌する除菌部の取り付けやメンテナンスを容易にできる車両用空気調和装置及びそれに用いるフィルタユニットを提供することを目的とする。 An object of the present invention is to provide a vehicle air conditioner that can easily attach and maintain a sterilization unit for sterilizing air, and a filter unit used therefor.
　上記目的を達成するために本発明は、空気中の塵埃を捕集するフィルタと前記フィルタを保持するフレームとを備えて車両用空気調和装置に対して着脱自在に設けられるフィルタユニットにおいて、空気を除菌する除菌部を前記フレームに設けたことを特徴としている。 In order to achieve the above object, the present invention provides a filter unit that includes a filter that collects dust in the air and a frame that holds the filter, and is detachably provided to a vehicle air conditioner.

Dust in the air sucked into the vehicle air conditioner is collected by a filter. In addition, airborne bacteria in the air are sterilized by a sterilization unit provided in the frame. Thereby, the inside of the vehicle air conditioner and the passenger compartment are sterilized.
　また本発明は、上記構成のフィルタユニットにおいて、前記除菌部は通電によってイオン及びオゾンの一方または両方を発生させて空気中に放出すると好ましい。この構成によると、イオン及びオゾンの一方または両方によって車両用空気調和装置内及び車室内が除菌される。 In the filter unit configured as described above, it is preferable that the sterilizing unit generates one or both of ions and ozone by energization and releases them into the air. According to this configuration, the inside of the vehicle air conditioner and the vehicle interior are sterilized by one or both of ions and ozone.
　また本発明は、上記構成のフィルタユニットにおいて、前記除菌部は前記フィルタの排気面と同じ側の面に設けられているとより好ましい。 In the filter unit configured as described above, the sterilization section is more preferably provided on the same side as the exhaust surface of the filter.
　また本発明は、上記構成のフィルタユニットにおいて、前記除菌部の駆動電圧がＤＣ１２Ｖであることが好ましい。 In the filter unit having the above-described configuration, the sterilization unit preferably has a driving voltage of DC 12V.
　また本発明は、上記構成のフィルタユニットにおいて、車両のシガーソケットに挿入されるプラグを有することが好ましい。 Further, the present invention preferably has a plug inserted into a cigar socket of a vehicle in the filter unit configured as described above.
　また本発明は、上記構成のフィルタユニットにおいて、前記除菌部が薬剤を空気中に放出して除菌を行う着脱自在の薬剤放出部材をさらに有することが好ましい。 In the filter unit configured as described above, it is preferable that the sterilization unit further includes a detachable drug release member that performs sterilization by discharging the drug into the air.
　また本発明の車両用空気調和装置は、上記構成のフィルタユニットを備えたことを特徴としている。 The vehicle air conditioner of the present invention is characterized by including the filter unit having the above-described configuration.
　本発明によると、空気を除菌する除菌部をフィルタユニットのフレームに設けているので、空気を除菌する除菌部を使用者が車両用空気調和装置に容易に後付け設置でき、車両用空気調和装置内及び車室内を除菌できる。また、使用者が容易に除菌部のメンテナンスや交換を行うことができる。 According to the present invention, since the sterilization part for sterilizing the air is provided in the frame of the filter unit, the user can easily install the sterilization part for sterilizing the air retrofit to the vehicle air conditioner. The inside of the air conditioner and the passenger compartment can be sterilized. In addition, the user can easily perform maintenance and replacement of the sterilization unit.

　以下に本発明の第１実施形態を図面を参照して説明する。説明の便宜上、前述の図１５に示す従来例と同様な部分には同一の符号を付している。図１は車両用空気調和装置を備えた車両を示す側面断面図である。車両１は、エンジンルーム５、機器室４及び車室６に区画されている。エンジンルーム５と機器室４との間は隔壁７によって仕切られるとともに、機器室４と車室６との間はインストルメントパネル８によって仕切られている。 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. For convenience of explanation, the same reference numerals are given to the same parts as those in the conventional example shown in FIG. FIG. 1 is a side sectional view showing a vehicle equipped with a vehicle air conditioner. The vehicle 1 is divided into an engine room 5, an equipment room 4, and a vehicle room 6. The engine room 5 and the equipment room 4 are partitioned by a partition wall 7, and the equipment room 4 and the vehicle compartment 6 are partitioned by an instrument panel 8.
　エンジンルーム５の上面はボンネット３に覆われてエンジン（不図示）を収容している。車室６は乗員が乗り込む空間であり、椅子６０が備え付けられる。インストルメントパネル８の車室６に面する位置にはシガーソケット９が設けられる。機器室４には車両用空気調和装置２（HVAC：Heating,　Ventilation,　and　Air-Conditioning）が配置されている。 The upper surface of the engine room 5 is covered with a bonnet 3 and houses an engine (not shown). The vehicle compartment 6 is a space where passengers get in, and is provided with a chair 60. A cigar socket 9 is provided at a position facing the vehicle compartment 6 of the instrument panel 8. A vehicle air conditioner 2 (HVAC: Heating, Ventilation, and Air-Conditioning) is disposed in the equipment room 4.
　図２は車両用空気調和装置の概略構成を示す側面断面図である。車両用空気調和装置２はハウジング１０を有し、ハウジング１０には吸込口１１と吹出口１２とが開口する。吸込口１１は外気吸込口１１ａと内気吸込口１１ｂとから成る。外気吸込口１１ａは車両１の外部に連通して車両１外の空気（外気ＯＡ）を吸い込む。一方、内気吸込口１１ｂは車室６に連通して車室６内の空気（内気ＩＡ）を吸い込む。吹出口１２は車室６に連通して車室６内に調和空気ＣＡを吹き出す。そして、ハウジング１０内には外気吸込口１１ａ及び内気吸込口１１ｂと吹出口１２とを連通させる送風経路１３が設けられる。 FIG. 2 is a side sectional view showing a schematic configuration of the vehicle air conditioner. The vehicle air conditioner 2 has a housing 10, and a suction port 11 and an outlet 12 are opened in the housing 10. The suction port 11 includes an outside air suction port 11a and an inside air suction port 11b. The outside air inlet 11a communicates with the outside of the vehicle 1 and sucks air outside the vehicle 1 (outside air OA). On the other hand, the inside air suction port 11b communicates with the passenger compartment 6 and sucks air in the passenger compartment 6 (inside air IA). The air outlet 12 communicates with the passenger compartment 6 and blows out conditioned air CA into the passenger compartment 6. In the housing 10, an outside air suction port 11 a and an inside air suction port 11 b are connected to the air outlet 12.
　送風経路１３内には外気吸込口１１ａ及び内気吸込口１１ｂから吹出口１２に向かって（気流の上流側から下流側に向かって）、切換ダンパ３１、フィルタユニット１４、送風機１５、蒸発器１６、ヒーターコア１７が順に配されている。切換ダンパ３１は、外気吸込口１１ａ及び内気吸込口１１ｂを択一的に開閉して、外気ＯＡ及び内気ＩＡの吸込みの切換えを行う。フィルタユニット１４はフィルタ１４ａとフレーム１４ｂとを有し、フィルタ１４ａによって空気中の塵埃や花粉等の浮遊微粒子を除去する（図３参照）。また、フィルタユニット１４にはイオン発生装置１８（除菌部）が設けられている。イオン発生装置１８はイオン及びオゾンを発生して空気中に放出する。フィルタユニット１４及びイオン発生装置１８の詳細については後述する。 In the ventilation path 13, the switching damper 31, the filter unit 14, the blower 15, the evaporator 16, from the outside air inlet 11 a and the inside air inlet 11 b toward the outlet 12 (from the upstream side to the downstream side of the airflow) The heater core 17 is arranged in order. The switching damper 31 selectively opens and closes the outside air suction port 11a and the inside air suction port 11b to switch between the suction of the outside air OA and the inside air IA. The filter unit 14 includes a filter 14a and a frame 14b. The filter 14a removes suspended particulates such as dust and pollen in the air (see FIG. 3). Further, the filter unit 14 is provided with an ion generator 18 (sanitization part). The ion generator 18 generates ions and ozone and releases them into the air. Details of the filter unit 14 and the ion generator 18 will be described later.
　送風機１５は例えばモータにより回転されるファンを有するシロッコファンから構成される。送風機１５の駆動により外気吸込口１１ａ及び内気吸込口１１ｂの一方から送風経路１３内に空気が取り込まれ、送風経路１３内に吹出口１２へ向かう気流が発生する。 The blower 15 is constituted by a sirocco fan having a fan rotated by a motor, for example. By driving the blower 15, air is taken into the blower path 13 from one of the outside air inlet 11 a and the inside air inlet 11 b, and an airflow toward the outlet 12 is generated in the blower path 13.
　蒸発器１６は気流の流通方向で送風機１５の下流側に送風経路１３を塞ぐように配されている。蒸発器１６は、入口配管（不図示）から流入した冷媒が流通する複数のチューブ（不図示）と表面を空気が流通するように配された複数のコルゲートフィン（不図示）とを有する。 The evaporator 16 is arranged on the downstream side of the blower 15 so as to block the blower path 13 in the flow direction of the airflow. The evaporator 16 has a plurality of tubes (not shown) through which refrigerant flowing from an inlet pipe (not shown) flows, and a plurality of corrugated fins (not shown) arranged so that air flows through the surface.
　蒸発器１６はエンジンルーム５（図１参照）と機器室４（図１参照）との間を流通する冷媒の循環流路（不図示）内に設けられている。循環流路には、圧縮機、凝縮器、レシーバ及び膨張弁が設けられている（いずれも不図示）。エンジンからＶベルト（不図示）を介して圧縮機に動力が伝達されると、圧縮機は循環流路内で冷媒を循環させる。冷媒は蒸発器１６で気化する。冷媒が気化しているときに蒸発器１６のコルゲートフィン間を空気が通過することによって、空気は気化熱を奪われて冷却される。これにより、車室６内の冷房が行われる。 The evaporator 16 is provided in a circulation path (not shown) of a refrigerant that circulates between the engine room 5 (see FIG. 1) and the equipment room 4 (see FIG. 1). The circulation flow path is provided with a compressor, a condenser, a receiver, and an expansion valve (all not shown). When power is transmitted from the engine to the compressor via a V belt (not shown), the compressor circulates the refrigerant in the circulation flow path. The refrigerant is vaporized by the evaporator 16. When air passes between corrugated fins of the evaporator 16 when the refrigerant is vaporized, the air is deprived of heat of vaporization and cooled. Thereby, the inside of the passenger compartment 6 is cooled.
　ヒーターコア１７は気流の流通方向で蒸発器１６の下流側に配されている。ヒーターコア１７はコルゲートチューブ（不図示）とコルゲートチューブの周りに設けられた多数の放熱フィンとを有する。ヒーターコア１７は、エンジンルーム５と機器室４との間を流れるエンジン冷却水の分流路（不図示）内に温水バルブ（不図示）とともに設けられている。分流路は、エンジンとラジエータ（不図示）との間を循環するエンジン冷却水の循環流路（不図示）にヒーターコア１７とラジエータとが並列になるように接続されている。エンジン冷却水が循環流路を循環しているときに温水バルブが開かれると、エンジンで加熱された冷却水（温水）が分流路に流入してヒーターコア１７のコルゲートチューブ内に流入する。そして、ヒーターコア１７の放熱フィン間を空気が通過することによって、空気は加熱される。これにより、車室６内の暖房が行われる。なお、冷房・暖房の切換はインストルメントパネル８に設けられた切換スイッチ（不図示）を使用者が操作することにより行われる。 The heater core 17 is arranged on the downstream side of the evaporator 16 in the air flow direction. The heater core 17 has a corrugated tube (not shown) and a large number of radiating fins provided around the corrugated tube. The heater core 17 is provided together with a hot water valve (not shown) in a flow path (not shown) of engine cooling water that flows between the engine room 5 and the equipment room 4. The branch flow path is connected so that the heater core 17 and the radiator are in parallel to a circulation path (not shown) of engine cooling water that circulates between the engine and the radiator (not shown). When the hot water valve is opened while the engine cooling water is circulating in the circulation flow path, the cooling water (hot water) heated by the engine flows into the branch flow path and flows into the corrugated tube of the heater core 17. The air is heated by the passage of air between the heat dissipating fins of the heater core 17. Thereby, the vehicle interior 6 is heated. The switching between cooling and heating is performed by the user operating a changeover switch (not shown) provided on the instrument panel 8.
　送風機１５の駆動によって外気吸込口１１ａ及び内気吸込口１１ｂの一方から空気が送風経路１３内に吸い込まれ、送風経路１３内に吹出口１２へ向かう気流が発生する。空気に含まれる塵挨や花粉等の浮遊微粒子はフィルタユニット１４のフィルタ１４ａによって除去される。塵挨等が除去された空気は冷房運転時には蒸発器１６で冷却される。その後、吹出口１２から車室６内に空気が送出される。これにより、車室６内の冷房が行われる。暖房運転時には、塵挨等が除去された空気はヒーターコア１７によって加熱されて吹出口１２から車室６内に送出される。これにより、車室６内が暖房される。 By driving the blower 15, air is sucked into the blower path 13 from one of the outside air inlet 11 a and the inside air inlet 11 b, and an airflow toward the outlet 12 is generated in the blower path 13. Airborne particles such as dust and pollen contained in the air are removed by the filter 14 a of the filter unit 14. The air from which dust and the like have been removed is cooled by the evaporator 16 during the cooling operation. Thereafter, air is sent from the air outlet 12 into the passenger compartment 6. Thereby, the inside of the passenger compartment 6 is cooled. During the heating operation, the air from which dust and the like have been removed is heated by the heater core 17 and sent out from the outlet 12 into the vehicle compartment 6. Thereby, the interior of the passenger compartment 6 is heated.
　図３はフィルタユニット１４をフィルタ１４ａの排気側から見た斜視図である。Ｓは送風機１５の駆動により発生した気流を示している。フィルタ１４ａは、外気吸込口１１ａ及び内気吸込口１１ｂから吸い込まれた空気に含まれる塵挨や花粉等の浮遊微粒子を除去する。フィルタ１４ａとしては、例えば不織布で構成された多孔質の濾過材を使用することができる。なお、表面積を大きくするためにフィルタ１４ａを波形形状にしている。 FIG. 3 is a perspective view of the filter unit 14 as viewed from the exhaust side of the filter 14a. S indicates an air flow generated by driving the blower 15. The filter 14a removes suspended particulates such as dust and pollen contained in the air sucked from the outside air suction port 11a and the inside air suction port 11b. As the filter 14a, for example, a porous filter medium made of a nonwoven fabric can be used. In order to increase the surface area, the filter 14a has a corrugated shape.
　フレーム１４ｂは中央部に開口部１４ｃを有する枠形状に形成されている。フレーム１４ｂ内にフィルタ１４ａはフレーム１４ｂに対して着脱自在に保持される。これにより、フィルタ１４ａをフレーム１４ｂから取り外して容易に交換できる。また、フレーム１４ｂは例えば樹脂から構成される。これにより、フレーム１４ｂの加工が容易になる。フレーム１４ｂの形状に特に限定はなく、フィルタ１４ａの排気側から見て円形形状や楕円形状であってもよい。 The frame 14b is formed in a frame shape having an opening 14c at the center. The filter 14a is detachably held in the frame 14b with respect to the frame 14b. Thereby, the filter 14a can be removed from the frame 14b and easily replaced. The frame 14b is made of resin, for example. This facilitates processing of the frame 14b. The shape of the frame 14b is not particularly limited, and may be circular or elliptical when viewed from the exhaust side of the filter 14a.
　フレーム１４ｂのフィルタ１４ａの排気面と同じ側の面には凹部１４ｄが設けられる。凹部１４ｄにはイオン発生装置１８（除菌部）がフレーム１４ｂに対して着脱自在に取り付けられる。この時、イオン発生装置１８はイオン発生部１８ａ、１８ｂがフィルタ１４ａの風下側を向くように配置される。これにより、イオン発生装置１８により発生したイオンやオゾンがフィルタ１４ａに衝突して消滅することを防止できる。従って、車両用空気調和装置２内及び車室６内を効率良く除菌することができる。 A recess 14d is provided on the surface of the frame 14b on the same side as the exhaust surface of the filter 14a. An ion generator 18 (sanitizing part) is detachably attached to the recess 14d with respect to the frame 14b. At this time, the ion generator 18 is arranged so that the ion generators 18a and 18b face the leeward side of the filter 14a. Thereby, it is possible to prevent ions and ozone generated by the ion generator 18 from colliding with the filter 14a and disappearing. Therefore, the inside of the vehicle air conditioner 2 and the inside of the passenger compartment 6 can be sterilized efficiently.
　凹部１４ｄの側面にはイオン発生装置１８に設けられたコネクタ１８４（図６参照）が嵌合するコネクタ嵌合部（不図示）が設けられる。コネクタ嵌合部には電源ケーブル１９の一端が接続され、電源ケーブル１９の他端はフレーム１４ｂの側面から引き出されて駆動電源２０に接続される。駆動電源２０はシガーソケット９（図１参照）に挿入されるプラグ２０ａを有する。 A connector fitting portion (not shown) into which a connector 184 (see FIG. 6) provided in the ion generator 18 is fitted is provided on the side surface of the recess 14d.

The drive power supply 20 has a plug 20a inserted into the cigar socket 9 (see FIG. 1).
　また、駆動電源２０には駆動回路２０ｂ、第１昇圧回路２０ｃ及び第２昇圧回路２０ｄ（いずれも図７参照）とマイクロコンピュータからなる制御装置(不図示)とが内蔵されて電源制御される。これにより、駆動電源２０にはシガーソケット９から例えばＤＣ１２Ｖの電圧が印加され、イオン発生装置１８に電力が供給される。なお、車両１のバッテリー（不図示）から駆動電源２０に直接電圧（例えば、ＤＣ１２Ｖ）が印加されてもよい。 The drive power supply 20 includes a drive circuit 20b, a first booster circuit 20c, a second booster circuit 20d (all of which are shown in FIG. 7), and a control device (not shown) composed of a microcomputer for power supply control. As a result, a voltage of, for example, DC 12 V is applied from the cigar socket 9 to the drive power source 20, and power is supplied to the ion generator 18. Note that a voltage (for example, DC 12 V) may be applied directly from the battery (not shown) of the vehicle 1 to the drive power supply 20.
　イオン発生装置１８に電力が供給されると、放電によりイオン及びオゾンを発生し、フィルタ１４ａを通過した空気にイオン及びオゾンを放出する。なお、イオン発生装置１８の詳細は後述する（図６参照）。 When power is supplied to the ion generator 18, ions and ozone are generated by discharge, and the ions and ozone are released to the air that has passed through the filter 14a. Details of the ion generator 18 will be described later (see FIG. 6).
　図４、図５はフィルタユニット１４を車両用空気調和装置２に取り付けた状態を示している。図４はフィルタユニット１４の上面断面図、図５はフィルタユニット１４の側面断面図である。フィルタユニット１４はフィルタ１４ａの排気面側を下にして車両用空気調和装置２に取り付けられている。 4 and 5 show a state in which the filter unit 14 is attached to the vehicle air conditioner 2.

　Ｓは送風機１５の駆動により生じた気流である。ハウジング１０の内壁には凹部４１が設けられている。使用者がインストルメントパネル８（図１参照）に設けられたグローブボックス（不図示）を取り外してフィルタユニット１４を凹部４１内に挿入することができる。これにより、フィルタユニット１４は車両用空気調和装置２に対して着脱自在に取り付けられる。従って、フィルタユニット１４を容易に交換できる。 S is an airflow generated by driving the blower 15. A recess 41 is provided on the inner wall of the housing 10. The user can remove the glove box (not shown) provided on the instrument panel 8 (see FIG. 1) and insert the filter unit 14 into the recess 41. Thereby, the filter unit 14 is detachably attached to the vehicle air conditioner 2. Therefore, the filter unit 14 can be easily replaced.
　この時、イオン発生装置１８のイオン発生部１８ａ、１８ｂが送風経路１３に面するように取り付けられる。そして、電源ケーブル１９はグローブボックスとインストルメントパネル８との間の隙間から車室６内に引き出され、プラグ２０ａがシガーソケット９（図１参照）に挿入される。 At this time, the ion generators 18 a and 18 b of the ion generator 18 are attached so as to face the air blowing path 13. Then, the power cable 19 is drawn into the vehicle compartment 6 from the gap between the glove box and the instrument panel 8, and the plug 20a is inserted into the cigar socket 9 (see FIG. 1).
　フィルタユニット１４を車両用空気調和装置２に取り付けた状態では、フィルタ１４ａは気流Ｓ中に配置される。これにより、気流Ｓ中に含まれる塵挨や花粉等の浮遊微粒子はフィルタ１４ａによって除去される。また、イオン発生装置１８は気流Ｓ中に配置されるとともに、イオン発生部１８ａ、１８ｂ（図３、図６参照）が気流Ｓの流通方向でフィルタユニット１４の下流側を向くように配置されている。これにより、イオン発生装置１８により発生したイオンやオゾンがフィルタ１４ａに衝突して消滅することを防止できる。 In the state where the filter unit 14 is attached to the vehicle air conditioner 2, the filter 14a is disposed in the airflow S. Thereby, suspended fine particles such as dust and pollen contained in the airflow S are removed by the filter 14a. The ion generator 18 is disposed in the airflow S, and the ion generators 18a and 18b (see FIGS. 3 and 6) are disposed so as to face the downstream side of the filter unit 14 in the flow direction of the airflow S. Yes. Thereby, it is possible to prevent ions and ozone generated by the ion generator 18 from colliding with the filter 14a and disappearing.
　図６は、イオン発生装置１８の一部を破断した斜視図を示している。イオン発生装置１８は絶縁体から成るハウジング１８０により覆われている。ハウジング１８０内には、基板１８３が設けられている。基板１８３には針状の放電電極１８１ａ、１８１ｂが互いに離れて配置されているとともに、放電電極１８１ａ、１８１ｂに対向する環状の対向電極１８２ａ、１８２ｂが配置されている。放電電極１８１ａ、１８１ｂと対向電極１８２ａ、１８２ｂとの間にはそれぞれイオン発生部１８ａ、１８ｂが形成される。 FIG. 6 shows a perspective view in which a part of the ion generator 18 is broken. The ion generator 18 is covered with a housing 180 made of an insulator. A substrate 183 is provided in the housing 180. On the substrate 183, needle- like discharge electrodes 181a and 181b are arranged apart from each other, and annular counter electrodes 182a and 182b facing the discharge electrodes 181a and 181b are arranged. Ion generators 18a and 18b are formed between the discharge electrodes 181a and 181b and the counter electrodes 182a and 182b, respectively.
　ハウジング１８０には放電電極１８１ａに対向する貫通孔（不図示）、放電電極１８１ｂに対向する貫通孔１８５ｂが設けられる。これにより、イオン発生部１８ａ、１８ｂがハウジング１８０の外部に露出する。放電電極１８１ａ、１８１ｂには対向電極１８２ａ、１８２ｂに対して負極性または正極性の高電圧（例えば、約２ｋＶ）がそれぞれ印加される。これにより、イオン発生部１８ａ、１８ｂに例えばコロナ放電によりそれぞれマイナスイオン、プラスイオンが発生する。 The housing 180 is provided with a through hole (not shown) facing the discharge electrode 181a and a through hole 185b facing the discharge electrode 181b. As a result, the ion generators 18 a and 18 b are exposed to the outside of the housing 180. A high voltage (for example, about 2 kV) having a negative polarity or a positive polarity is applied to the discharge electrodes 181a and 181b with respect to the counter electrodes 182a and 182b, respectively. Thereby, negative ions and positive ions are generated in the ion generators 18a and 18b, for example, by corona discharge.
　例えば、一方の放電電極１８１ｂには正電圧が印加され、電離により発生するイオンが空気中の水分と結合して主としてＨ+（Ｈ2Ｏ）ｍから成る電荷が正のクラスタイオンを発生する。他方の放電電極１８１ａには負電圧が印加され、電離により発生するイオンが空気中の水分と結合して主としてＯ2 -（Ｈ2Ｏ）ｎから成る電荷が負のクラスタイオンを発生する。ここで、ｍ、ｎは任意の自然数である。Ｈ+（Ｈ2Ｏ）ｍ及びＯ2 -（Ｈ2Ｏ）ｎは空気中の浮遊菌、車両用空気調和装置２及び車室６に付着した付着菌、及び臭い成分の表面で凝集してこれらを取り囲む。 For example, a positive voltage is applied to one of the discharge electrodes 181b, and ions generated by ionization combine with moisture in the air to generate positive cluster ions whose charges mainly consist of H + (H 2 O) m. A negative voltage is applied to the other discharge electrode 181a, and ions generated by ionization are combined with moisture in the air to generate negatively clustered ions mainly composed of O 2 − (H 2 O) n. Here, m and n are arbitrary natural numbers. H + (H 2 O) m and O 2 − (H 2 O) n are aggregated on the surface of airborne bacteria, adhering bacteria attached to the vehicle air conditioner 2 and the vehicle compartment 6, and odor components. Surround these.
　そして、式（１）～（３）に示すように、衝突により活性種である［・ＯＨ］（水酸基ラジカル）やＨ2Ｏ2（過酸化水素）を微生物等の表面上で凝集生成して浮遊菌等や臭い成分等を破壊する。ここで、ｍ’、ｎ’は任意の自然数である。従って、プラスイオン及びマイナスイオンを発生してフィルタ１４ａを通過した気流Ｓに放出することにより、車両用空気調和装置２内及び車室６内の殺菌、ウイルスの不活化及び臭い除去を行うことができる。 Then, as shown in the formulas (1) to (3), the active species [.OH] (hydroxyl radical) and H 2 O 2 (hydrogen peroxide) are agglomerated on the surface of the microorganism or the like by collision. Destroy airborne bacteria and odor components. Here, m ′ and n ′ are arbitrary natural numbers. Therefore, by generating positive ions and negative ions and releasing them into the airflow S that has passed through the filter 14a, sterilization, inactivation of viruses, and removal of odors in the vehicle air conditioner 2 and the passenger compartment 6 can be performed. it can.
　また、放電電極１８１ａ、１８１ｂに印加する電圧をより高くすると、放電によってイオン発生部１８ａ、１８ｂからイオン及びオゾンが放出される。オゾンの酸化力によって殺菌及び脱臭を行うことができる。 Further, when the voltage applied to the discharge electrodes 181a and 181b is further increased, ions and ozone are released from the ion generating portions 18a and 18b by the discharge. Sterilization and deodorization can be performed by the oxidizing power of ozone.

　また、ハウジング１８０には側面から突出したコネクタ１８４が設けられる。コネクタ１８４はフレーム１４ｂのコネクタ嵌合部に嵌合する。これにより、イオン発生装置１８に電力が供給される。 Also, the housing 180 is provided with a connector 184 protruding from the side surface. The connector 184 is fitted into the connector fitting portion of the frame 14b. Thereby, electric power is supplied to the ion generator 18.

　図７の回路構成において、マイクロコンピュータからなる制御装置（不図示）によって制御入力Ｍ１に駆動信号が与えられると、ＮＰＮトランジスタＱ１がオンになる。そして、電源入力Ｖ１及び接地入力Ｇ１の間にシガーソケット９（直流電源Ｅ１）のＤＣ１２Ｖが印加される。このとき、ダイオードＤ１、抵抗Ｒ３及び起動抵抗Ｒ４を介して流入したベース電流により、ＮＰＮトランジスタＱ２のコレクタ電流が流れ始める。そして、昇圧トランスＴ１の一次巻線Ｔ１ａの両端に電圧が発生する。これにより、ベース巻線Ｔ１ｂの両端に一次巻線Ｔ１ａ及びベース巻線Ｔ１ｂの巻数比に応じた電圧が発生する。 In the circuit configuration of FIG. 7, when a drive signal is given to the control input M1 by a control device (not shown) composed of a microcomputer, the NPN transistor Q1 is turned on. And DC12V of the cigar socket 9 (DC power supply E1) is applied between the power supply input V1 and the ground input G1. At this time, the collector current of the NPN transistor Q2 starts to flow due to the base current flowing in via the diode D1, the resistor R3, and the starting resistor R4. A voltage is generated across the primary winding T1a of the step-up transformer T1. As a result, a voltage corresponding to the turn ratio of the primary winding T1a and the base winding T1b is generated at both ends of the base winding T1b.
　ここで、昇圧トランスＴ１のベース巻線Ｔ１ｂは一次巻線Ｔ１ａと同極性である。そのため、ベース巻線Ｔ１ｂの両端に発生した電圧はＮＰＮトランジスタＱ２のコレクタ電流の増加を加速させて一次巻線の両端の電圧を増加させるように作用する。このとき、二次巻線Ｔ１ｃの極性はダイオードＤ３が導通しない方向の電圧が発生するように設定されている。このため、二次巻線Ｔ１ｃには電流が流れない。 Here, the base winding T1b of the step-up transformer T1 has the same polarity as the primary winding T1a. Therefore, the voltage generated at both ends of the base winding T1b acts to accelerate the increase in the collector current of the NPN transistor Q2 and increase the voltage at both ends of the primary winding. At this time, the polarity of the secondary winding T1c is set so that a voltage is generated in a direction in which the diode D3 does not conduct. For this reason, no current flows through the secondary winding T1c.
　その後、ＮＰＮトランジスタＱ２のコレクタ電流が増加する割合が減少した場合、一次巻線Ｔ１ａの両端の電圧は低下し始める。また、ベース巻線Ｔ１ｂの両端の電圧も低下してベース電流及びコレクタ電流が減少する。そのため、一次巻線Ｔ１ａの両端の電圧はさらに加速度的に低下する。このとき、二次巻線Ｔ１ｃの両端にはダイオードＤ３が導通する方向に電圧が発生してコンデンサＣ１を充電する。 Thereafter, when the rate at which the collector current of the NPN transistor Q2 increases decreases, the voltage across the primary winding T1a begins to decrease. Further, the voltage at both ends of the base winding T1b is also reduced, and the base current and the collector current are reduced. Therefore, the voltage across the primary winding T1a further decreases at an accelerated rate. At this time, a voltage is generated across the secondary winding T1c in the direction in which the diode D3 conducts to charge the capacitor C1.
　コンデンサＣ１の充電が進行して電圧が二端子サイリスタＳ１のブレークオーバー電圧（例えば、約１００Ｖ）に達した場合、二端子サイリスタＳ１はツェナーダイオードのように導通し始める。導通する電流がブレークオーバー電流（例えば１ｍＡ）に達した場合、二端子サイリスタＳ１は略短絡状態となり、コンデンサＣ１に充電された電荷が昇圧トランスＴ２の一次巻線Ｔ２ａを通じて接地電位に放電する。 When the charging of the capacitor C1 proceeds and the voltage reaches the breakover voltage (for example, about 100 V) of the two-terminal thyristor S1, the two-terminal thyristor S1 starts to conduct like a Zener diode. When the conducting current reaches a breakover current (for example, 1 mA), the two-terminal thyristor S1 is substantially short-circuited, and the charge charged in the capacitor C1 is discharged to the ground potential through the primary winding T2a of the step-up transformer T2.
　このとき、二次巻線Ｔ２ｂには、昇圧されたインパルス状の高電圧が発生する。これにより、昇圧トランスＴ２の二次巻線Ｔ２ｂからダイオードＤ４、Ｄ５を介してイオン発生装置１８に高電圧（例えば、２ｋＶ）が印加される。そして、放電電極１８１ａと対向電極１８２ａとの間でマイナスイオンを発生させるとともに、放電電極１８１ｂと対向電極１８２ｂとの間でプラスイオンを発生させる。 At this time, a boosted impulse-like high voltage is generated in the secondary winding T2b. Thereby, a high voltage (for example, 2 kV) is applied to the ion generator 18 from the secondary winding T2b of the step-up transformer T2 via the diodes D4 and D5. Then, negative ions are generated between the discharge electrode 181a and the counter electrode 182a, and positive ions are generated between the discharge electrode 181b and the counter electrode 182b.

　２つのイオン発生装置１８、１８はフレーム１４ｂの凹部１４ｄ、１４ｄに配置され、フィルタ１４ａの排気面と同じ側の面に配されている。これにより、イオン発生装置１８、１８により発生したイオン及びオゾンがフィルタ１４ａに衝突して消滅することを防止できる。また、イオン発生装置１８、１８はフィルタ１４ａに対して互いに反対側の位置に設けられる。これにより、フィルタ１４ａを通過した気流Ｓに均一にイオン及びオゾンを含ませることができる。したがって、除菌効果がより向上する。なお、イオン発生装置１８を３つ以上設けてもよい。 The two ion generators 18 and 18 are disposed in the recesses 14d and 14d of the frame 14b, and are arranged on the same side as the exhaust surface of the filter 14a. Thereby, it is possible to prevent ions and ozone generated by the ion generators 18 and 18 from colliding with the filter 14a and disappearing. The ion generators 18 and 18 are provided at positions opposite to each other with respect to the filter 14a. Thereby, ion and ozone can be uniformly included in the airflow S that has passed through the filter 14a. Therefore, the sterilization effect is further improved. Three or more ion generators 18 may be provided.
　図９は、フィルタユニット２４に設けたイオン発生装置１８、１８と駆動電源２０との接続を示す回路図である。説明の便宜上、前述の図７に示す第１実施形態と同様な部分には同一の符号を付している。なお、駆動電源２０及びイオン発生装置１８の回路構成は第１実施形態（図７参照）と同一であるので、ここでは説明を省略する。 FIG. 9 is a circuit diagram showing the connection between the ion generators 18 and 18 provided in the filter unit 24 and the drive power supply 20. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIG. Since the circuit configurations of the drive power supply 20 and the ion generator 18 are the same as those in the first embodiment (see FIG. 7), description thereof is omitted here.
　イオン発生装置１８はコネクタ１８４（図６参照）がコネクタ嵌合部５２に嵌合することによって駆動電源２０から電力が供給される。本実施形態では、２つのイオン発生装置１８、１８に対応させて２つのコネクタ嵌合部５２がフレーム１４ｂに設けられている。電源ケーブル１９の一端は駆動電源２０に接続されるとともに、他端は一方のコネクタ嵌合部５２に接続される。そして、一方のコネクタ嵌合部５２には連結ケーブル１９ａの一端が接続されるとともに、連結ケーブル１９ａの他端は他方のコネクタ嵌合部５２に接続される。これにより、一つの駆動電源２０から２つのイオン発生装置１８、１８に電力を供給することができる。 The ion generator 18 is supplied with electric power from the drive power supply 20 when the connector 184 (see FIG. 6) is fitted into the connector fitting portion 52. In the present embodiment, two connector fitting portions 52 are provided on the frame 14b so as to correspond to the two ion generators 18, 18. One end of the power cable 19 is connected to the drive power source 20 and the other end is connected to one connector fitting portion 52. One end of the connecting cable 19 a is connected to one connector fitting portion 52, and the other end of the connecting cable 19 a is connected to the other connector fitting portion 52. Thereby, electric power can be supplied to the two ion generators 18 and 18 from one drive power supply 20.
　なお、一方のイオン発生装置１８をフィルタ１４ａの排気面と同じ側の面に配置するとともに、他方のイオン発生装置１８をフィルタ１４ａの吸気面と同じ側の面に配置してもよい。これにより、フィルタ１４ａの吸気側も除菌できる。 Note that one ion generator 18 may be arranged on the same side as the exhaust surface of the filter 14a, and the other ion generator 18 may be arranged on the same side as the intake surface of the filter 14a. Thereby, the suction side of the filter 14a can also be sterilized.
　また、２つのイオン発生装置１８、１８をフィルタ１４ａに対して同じ側の位置に並設してもよい。これにより、連結ケーブル１９ａの長さを短くすることができる。従って、連結ケーブル１９ａの断線のおそれが少なくなる。また、製造コストを削減できる。 Further, the two ion generators 18 and 18 may be arranged in parallel on the same side with respect to the filter 14a. Thereby, the length of the connection cable 19a can be shortened. Therefore, the risk of disconnection of the connecting cable 19a is reduced. Further, the manufacturing cost can be reduced.
　本実施形態によれば、第１実施形態と同様な効果を奏する。また、フレーム１４ｂにはイオン発生装置１８を２つ設けているので、送風経路１３内のイオンやオゾンの濃度を容易に上昇させることができる。従って、除菌効果を一層向上できる。 According to the present embodiment, the same effects as in the first embodiment can be obtained. Moreover, since the two ion generators 18 are provided in the flame | frame 14b, the density | concentration of the ion in the ventilation path | route 13 and ozone can be raised easily. Therefore, the sterilization effect can be further improved.
　次に第３実施形態について説明する。図１０は本実施形態のフィルタユニット３４をフィルタ１４ａの排気側から見た斜視図である。本実施形態では、第１実施形態のフィルタユニットにイオン発生装置１８に加えて薬剤放出部材３５をさらに設けた点で第１実施形態と異なっている。その他の部分は第１実施形態と同様である。なお、説明の便宜上、前述の図３に示す第１実施形態と同様な部分には同一の符号を付している。 Next, a third embodiment will be described. FIG. 10 is a perspective view of the filter unit 34 of the present embodiment as viewed from the exhaust side of the filter 14a. The present embodiment is different from the first embodiment in that a drug release member 35 is further provided in addition to the ion generator 18 in the filter unit of the first embodiment. Other parts are the same as those in the first embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIG.
　薬剤放出部材３５は薬剤を空気中に放出して除菌を行う。イオン発生装置１８及び薬剤放出部材３５はフレーム１４ｂの凹部１４ｄ内に設けられ、フィルタ１４ａの排気面と同じ側の面に配されている。 The drug release member 35 performs sterilization by releasing the drug into the air. The ion generator 18 and the drug release member 35 are provided in the recess 14d of the frame 14b, and are arranged on the same side as the exhaust surface of the filter 14a.
　これにより、イオン発生装置１８により発生したイオン及びオゾンがフィルタ１４ａに衝突して消滅することを防止できるとともに、薬剤放出部材３５から放出された薬剤がフィルタ１４ａに吸着することを防止できる。また、薬剤放出部材３５はフレーム１４ｂに対して着脱自在に設けられる。これにより、薬剤放出部材３５を容易に交換できる。 Thereby, the ions and ozone generated by the ion generator 18 can be prevented from colliding with the filter 14a and disappearing, and the medicine released from the medicine release member 35 can be prevented from adsorbing to the filter 14a. The medicine release member 35 is detachably attached to the frame 14b. Thereby, the medicine release member 35 can be easily replaced.
　また、薬剤放出部材３５はフィルタ１４ａに対してイオン発生装置１８と反対側の位置に設けられる。これにより、イオン発生装置１８と薬剤放出部材３５とは互いに離れた位置に配される。従って、イオン発生装置１８によって発生して空気中に放出されたイオン及びオゾンと薬剤放出部材３５から空気中に放出された薬剤とが放出直後に相互作用することを防止できる。その結果、各々による除菌効果が減殺されることを防止できる。 Further, the drug release member 35 is provided at a position opposite to the ion generator 18 with respect to the filter 14a. Thereby, the ion generator 18 and the chemical | medical agent discharge | release member 35 are distribute | arranged to the position mutually separated. Therefore, it is possible to prevent the ions and ozone generated by the ion generator 18 and released into the air from interacting with the drug released into the air from the drug release member 35 immediately after the release. As a result, the sterilization effect by each can be prevented from being reduced.
　図１１は薬剤放出部材３５を示す正面斜視図である。図１２は薬剤放出部材３５を示す側面断面図である。薬剤放出部材３５は、薬剤を保持するペレット３５ｂを収容するケース３５ａを有する。ケース３５ａの一面には複数の開口部３５ｃが設けられる。そして、薬剤放出部材３５は開口部３５ｃが送風経路１３に面するようにフレーム１４ｂに設けられる。ペレット３５ｂから放出された薬剤は開口部３５ｃを介してケース３５ａ外に放出される。これにより、フィルタ１４ａを通過する気流Ｓに薬剤が含まれる。なお、ペレット３５ｂはろ紙などに置き換えてもよい。この場合、薬剤をろ紙に染み込ませる。 FIG. 11 is a front perspective view showing the drug release member 35. FIG. 12 is a side sectional view showing the drug release member 35. The medicine release member 35 has a case 35a that accommodates a pellet 35b that holds the medicine. A plurality of openings 35c are provided on one surface of the case 35a. Then, the medicine release member 35 is provided on the frame 14 b so that the opening 35 c faces the blower path 13. The medicine released from the pellet 35b is released out of the case 35a through the opening 35c. Thereby, a chemical | medical agent is contained in the airflow S which passes the filter 14a. The pellet 35b may be replaced with filter paper or the like. In this case, the drug is soaked into the filter paper.
　薬剤としては、例えばオルトフェニルフェノール、ジフェニル、２－イソプロピル－５－メチルフェノール、ヒノキチオール等の揮発性の除菌剤を使用できる。なお、専らイオン発生装置１８に除菌機能を担わせる場合には、薬剤放出部材３５の薬剤を除菌剤に替えて芳香剤としてもよい。これにより、車両用空気調和装置２内及び車室６内を除菌しながら車室６内で好みの香りを楽しむことができる。 As the drug, for example, a volatile disinfectant such as orthophenylphenol, diphenyl, 2-isopropyl-5-methylphenol, hinokitiol can be used. In addition, when the ion generator 18 is exclusively responsible for the sterilization function, the medicine of the medicine release member 35 may be replaced with a sterilizing agent and used as a fragrance. Thereby, favorite fragrance can be enjoyed in the vehicle interior 6 while disinfecting the vehicle air conditioner 2 and the vehicle interior 6.
　なお、イオン発生装置１８及び薬剤放出部材３５の一方をフィルタ１４ａの排気面と同じ側の面に配置するとともに、他方をフィルタ１４ａの吸気面と同じ側の面に配置してもよい。これにより、フィルタ１４ａの吸気側も除菌できる。 One of the ion generator 18 and the drug release member 35 may be disposed on the same surface as the exhaust surface of the filter 14a, and the other may be disposed on the same surface as the intake surface of the filter 14a. Thereby, the suction side of the filter 14a can also be sterilized.
　また、薬剤放出部材３５をシート状にしてもよい。この時、シートの一面に薬剤を塗布するとともに他面に接着剤を塗布してフレーム１４ｂに貼付すると好ましい。これにより、フレームユニット３４の製造効率を向上できる。 Further, the drug release member 35 may be formed into a sheet shape. At this time, it is preferable that the medicine is applied to one surface of the sheet and the adhesive is applied to the other surface and attached to the frame 14b. Thereby, the manufacturing efficiency of the frame unit 34 can be improved.
　本実施形態によれば、第１実施形態と同様な効果を奏する。また、イオンやオゾンで除菌しきれない微生物等を薬剤で除菌することができる。また、車両１が駐車中でシガーソケット９から電源供給されない場合でも薬剤放出部材３５から空気中に薬剤が放出される。従って、車両用空気調和装置２内及び車室６内を一層確実に除菌することができる。 According to the present embodiment, the same effects as in the first embodiment can be obtained. In addition, microorganisms that cannot be sterilized with ions or ozone can be sterilized with drugs. Further, even when the vehicle 1 is parked and no power is supplied from the cigar socket 9, the medicine is released from the medicine release member 35 into the air. Therefore, the inside of the vehicle air conditioner 2 and the inside of the passenger compartment 6 can be sterilized more reliably.
　次に第４実施形態について説明する。図１３は本実施形態のフィルタユニット４４をフィルタ１４ａの排気側から見た斜視図である。本実施形態では、イオン発生装置１８の配置が第１実施形態と異なっている。その他の部分は第１実施形態と同様である。なお、説明の便宜上、前述の図３に示す第１実施形態と同様な部分には同一の符号を付している。 Next, a fourth embodiment will be described. FIG. 13 is a perspective view of the filter unit 44 of this embodiment as viewed from the exhaust side of the filter 14a. In the present embodiment, the arrangement of the ion generator 18 is different from that of the first embodiment. Other parts are the same as those in the first embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIG.
　イオン発生装置１８はフレーム１４ｂから気流Ｓの下流側に向かって突出して設けられている。そして、イオン発生部１８ａ、１８ｂがフィルタ１４ａの排気面に臨むように配置される。これにより、イオン発生装置１８により発生したイオンは迅速かつ容易に気流Ｓに含まれる。従って、イオン発生部１８ａ、１８ｂでイオンが滞留して消滅することを確実に防止できる。なお、本実施形態でも第１実施形態と同様な効果を得ることができる。 The ion generator 18 is provided so as to protrude from the frame 14b toward the downstream side of the airflow S. The ion generators 18a and 18b are arranged so as to face the exhaust surface of the filter 14a. Thereby, the ions generated by the ion generator 18 are quickly and easily included in the airflow S. Accordingly, it is possible to reliably prevent ions from staying and disappearing in the ion generating portions 18a and 18b. In this embodiment, the same effect as that of the first embodiment can be obtained.
　次に第５実施形態について説明する。図１４は本実施形態のフィルタユニット５４をフィルタ１４ａの排気側から見た斜視図である。本実施形態では、イオン発生装置１８の配置が第２実施形態と異なっている。その他の部分は第２実施形態と同様である。なお、説明の便宜上、前述の図８に示す第２実施形態と同様な部分には同一の符号を付している。 Next, a fifth embodiment will be described. FIG. 14 is a perspective view of the filter unit 54 of the present embodiment as viewed from the exhaust side of the filter 14a. In the present embodiment, the arrangement of the ion generator 18 is different from that of the second embodiment. Other parts are the same as those of the second embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those of the second embodiment shown in FIG.
　２つのイオン発生装置１８はフレーム１４ｂから気流Ｓの下流側に向かって突出して設けられている。そして、イオン発生部１８ａ、１８ｂがフィルタ１４ａの排気面に臨むように配置される。これにより、イオン発生装置１８により発生したイオンは迅速かつ容易に気流Ｓに含まれる。従って、イオン発生部１８ａ、１８ｂでイオンが滞留して消滅することを確実に防止できる。なお、本実施形態でも第２実施形態と同様な効果を得ることができる。 The two ion generators 18 are provided so as to protrude from the frame 14b toward the downstream side of the airflow S. The ion generators 18a and 18b are arranged so as to face the exhaust surface of the filter 14a. Thereby, the ions generated by the ion generator 18 are quickly and easily included in the airflow S. Accordingly, it is possible to reliably prevent ions from staying and disappearing in the ion generating portions 18a and 18b. In this embodiment, the same effect as that of the second embodiment can be obtained.
　第１～第５実施形態において、イオン発生装置１８に特に限定はなく、例えば誘電体で形成した基板上に放電電極を印刷して形成したイオン発生装置でもよい。また、管状の絶縁体表面および内面に金属電極を設けたイオン発生装置であってもよい。 In the first to fifth embodiments, the ion generator 18 is not particularly limited, and may be an ion generator formed by printing discharge electrodes on a substrate formed of a dielectric, for example. Moreover, the ion generator which provided the metal electrode in the tubular insulator surface and inner surface may be sufficient.
　第１～第５実施形態では、除菌部としてイオン発生装置１８を用いたが、オゾンのみを発生して空気中に放出するオゾン発生装置を用いてもよい。例えば、無声放電によってオゾンを生成するオゾナイザを使用することができる。この時、人体への影響を考慮してオゾン濃度を日本産業衛生協会の許容濃度である０．１ｐｐｍよりも低くなるように制御するのが好ましい。また、車両用空気調和装置２の吹出口１２にオゾン触媒を設けて、オゾン触媒を通過する空気に含まれるオゾンを吸着及び分解してもよい。これにより、車室６内にオゾンを漏出させずに車両用空気調和装置２内のオゾン濃度を上昇させて車両用空気調和装置２内を一層確実に除菌できる。また、送風経路１３内を流通する空気を一層確実に除菌できる。 In the first to fifth embodiments, the ion generator 18 is used as the sterilization unit, but an ozone generator that generates only ozone and releases it into the air may be used. For example, an ozonizer that generates ozone by silent discharge can be used. At this time, it is preferable to control the ozone concentration to be lower than 0.1 ppm which is the allowable concentration of the Japan Industrial Hygiene Association in consideration of the influence on the human body. Further, an ozone catalyst may be provided at the air outlet 12 of the vehicle air conditioner 2 to adsorb and decompose ozone contained in the air passing through the ozone catalyst. Thereby, the ozone concentration in the vehicle air conditioner 2 can be increased without causing ozone to leak into the passenger compartment 6, thereby further sterilizing the interior of the vehicle air conditioner 2. Moreover, the air which distribute | circulates the inside of the ventilation path 13 can be disinfected more reliably.
　第１～第５実施形態では、イオン発生装置１８をフィルタ１４ａの排気面と同じ側の面に配置しているが、フィルタ１４ａの吸気面と同じ側の面に配置してもよい。この場合、発生したイオンやオゾンがフィルタ１４ａに衝突して多少減少するが、除菌効果を得ることはできる。 In the first to fifth embodiments, the ion generator 18 is disposed on the same surface as the exhaust surface of the filter 14a, but may be disposed on the same surface as the intake surface of the filter 14a. In this case, the generated ions and ozone collide with the filter 14a and decrease somewhat, but a sterilizing effect can be obtained.
　また、第１～第５実施形態では、車両用空気調和装置２に配置されるフィルタユニットについて説明したが、その他の空気調和装置や空気清浄機等に配置してもよい。 In the first to fifth embodiments, the filter unit disposed in the vehicle air conditioner 2 has been described. However, the filter unit may be disposed in another air conditioner, an air purifier, or the like.
　本発明は、空気中の塵挨を捕集するフィルタユニット及びそれを備えた車両用空気調和装置に利用することができる。 The present invention can be used for a filter unit that collects dust in the air and a vehicle air conditioner including the filter unit.
