Description

本発明は、イオン風発生装置を備えた空気調和機に関する。   The present invention relates to an air conditioner provided with an ion wind generator.
空気調和機は、室内空気を熱交換器に循環させて、加熱,冷却,除湿等により調和された空気を室内に吹き出すことにより、室内を空気調和する。一方、近年、空気調和機に対して、温度,湿度の調節以外にも様々な機能が望まれている。ニーズの高い機能としては、空気清浄機能,空気調和機内部を清潔に保つ機能,静音機能,省エネ・エコロジー等がある。   The air conditioner circulates room air through a heat exchanger and blows out air conditioned by heating, cooling, dehumidification, and the like into the room, thereby air-conditioning the room. On the other hand, in recent years, various functions other than temperature and humidity control have been desired for air conditioners. The functions that are in high demand include the air cleaning function, the function of keeping the inside of the air conditioner clean, the silent function, energy saving and ecology.
空気清浄機能としては、ペットやタバコ等から発生する悪臭の除去や、菌,花粉等のアレルゲン物質の増殖抑制等の空気質改善機能等がある。従来の抗菌効果や脱臭効果を奏する空気調和機として、空気調和機の室内機内部に紫外線ランプを設置し、通風路の壁面となる吸込口グリル、室内機本体の上壁,前壁,側壁及び送風ファンの背面側に位置する導風板(ケーシング部)に光触媒を担持させるものがある(例えば、特許文献1参照)。紫外線ランプの紫外光により光触媒を励起して、悪臭や菌等の吸着物を酸化分解し、光触媒の機能を復活させ、継続して悪臭や菌を吸着させる。   As an air cleaning function, there are an air quality improvement function such as removal of malodors generated from pets, cigarettes and the like, and suppression of growth of allergen substances such as bacteria and pollen. As an air conditioner with conventional antibacterial and deodorizing effects, an ultraviolet lamp is installed inside the indoor unit of the air conditioner, and a suction grille serving as the wall surface of the ventilation path, the upper wall, front wall, side wall, There is one in which a photocatalyst is supported on an air guide plate (casing portion) located on the back side of a blower fan (for example, see Patent Document 1). The photocatalyst is excited by the ultraviolet light from the ultraviolet lamp to oxidize and decompose adsorbed substances such as bad odors and bacteria, thereby restoring the function of the photocatalyst and continuously adsorbing bad odors and bacteria.
他の従来技術として、空気調和機内部に放電電極と集塵電極を設けて空気清浄するものがある(例えば、特許文献2参照)。空気調和機内部に放電電極と集塵電極を配置するので、通風抵抗の増大を回避して空気清浄することができる。   As another prior art, there is one in which a discharge electrode and a dust collection electrode are provided inside an air conditioner to clean the air (for example, see Patent Document 2). Since the discharge electrode and the dust collecting electrode are arranged inside the air conditioner, it is possible to avoid the increase in ventilation resistance and clean the air.
一方、空気調和機運転時の送風ファンからの騒音が、就寝時やテレビ鑑賞の妨げとなる場合がある。騒音を低減する空気調和機として、送風ファンの羽根外径側又は羽根内径側に凹凸を形成して、流体を拡散させて騒音を低減させるものがある(例えば、特許文献3参照)。   On the other hand, noise from the blower fan during operation of the air conditioner may interfere with bedtime or television viewing. As an air conditioner that reduces noise, there is an air conditioner that forms irregularities on the blade outer diameter side or blade inner diameter side of the blower fan to diffuse the fluid to reduce noise (see, for example, Patent Document 3).
しかしながら、特許文献1に記載の空気調和機では、室内空気が紫外線ランプを通過する際に、圧力損失が生じて通過風量が低下し、熱交換効率が低下してしまう。従って、抗菌性能を発揮することはできるが、冷房・暖房能力が低下したり、消費電力が増大する可能性がある。また、紫外線ランプを搭載することより、コストアップや紫外光に対する樹脂劣化対策が必要となる。   However, in the air conditioner described in Patent Document 1, when indoor air passes through the ultraviolet lamp, pressure loss occurs, the amount of passing air decreases, and heat exchange efficiency decreases. Therefore, although antibacterial performance can be exhibited, there is a possibility that the cooling / heating ability may be reduced or the power consumption may be increased. In addition, since an ultraviolet lamp is mounted, it is necessary to increase the cost and take measures against resin deterioration against ultraviolet light.
特許文献2では、放電電極と集塵電極が熱交換器と送風ファンとの間に配置されるので、放電電極より発生したイオンは、送風ファンによって拡散されてしまう。従って、発生させたイオンを効率よく室内へ放出されることができず、イオン風を室内へ届けることが難しい。   In Patent Document 2, since the discharge electrode and the dust collecting electrode are disposed between the heat exchanger and the blower fan, ions generated from the discharge electrode are diffused by the blower fan. Therefore, the generated ions cannot be efficiently released into the room, and it is difficult to deliver the ion wind into the room.
特許文献3では、送風ファンを稼動させれば必ず送風ファン羽根と空気との間で乱流渦が発生し、少なからず騒音を発生させてしまう。   In Patent Document 3, if the blower fan is operated, a turbulent vortex is always generated between the blower fan blades and the air, and noise is generated not a little.

本発明は、空気を清浄し且つ騒音なく送風するイオン風発生装置を備え、室内のより広範囲にイオン風を吹き出すことができる空気調和機を提供することを課題とする。   An object of the present invention is to provide an air conditioner that includes an ion wind generator that cleans air and blows air without noise, and that can blow out the ion wind in a wider range in the room.
上記目的を達成するために本発明の空気調和機は、空気吸込口及び空気吹出口を有する筐体と、筐体内に配置された熱交換器と、室内空気を空気吸込口より吸い込み熱交換器を通してから空気吹出口より吹き出す送風ファンと、送風ファンの背面側から空気吹出口に向かって位置し送風ファンから空気吹出口に向かって気流を案内するケーシング部と、空気吹出口に位置し気流を上下方向に偏向する上下風向板と、イオン風を発生させるイオン風発生装置と、を備え、イオン風発生装置は、気流方向に沿うように配置され先端部が気流方向下流側に位置する金属針状電極と、対極電極板と、金属針状電極に電圧を印加する電圧発生装置と、を有し、金属針状電極の先端部及び対極電極板は送風ファンの下流側に位置する。   In order to achieve the above object, an air conditioner of the present invention includes a housing having an air suction port and an air outlet, a heat exchanger disposed in the housing, and a heat exchanger that sucks indoor air from the air suction port. A blower fan that blows out from the air outlet, a casing portion that is located from the back side of the blower fan toward the air outlet and guides the airflow from the blower fan to the air outlet, and an airflow that is located at the air outlet. A metal needle having an up / down wind direction plate that deflects in an up / down direction and an ion wind generating device that generates ion wind, the ion wind generating device being arranged along the air flow direction and having a tip positioned downstream in the air flow direction And a voltage generator for applying a voltage to the metal needle electrode, the tip of the metal needle electrode and the counter electrode plate are located downstream of the blower fan.
本発明によれば、空気を清浄し且つ騒音なく送風するイオン風発生装置を備え、室内のより広範囲にイオン風を吹き出すことができる空気調和機を提供することができる。   According to the present invention, it is possible to provide an air conditioner that includes an ion wind generator that cleans air and blows air without noise, and that can blow out the ion wind over a wider range in the room.

以下、本発明の空気調和機の実施例を図面を用いて説明する。まず、空気調和機の全体構成について図1及び図2を用いて説明する。図1は空気調和機の構成図、図2は室内機の側断面図である。   Hereinafter, embodiments of the air conditioner of the present invention will be described with reference to the drawings. First, the whole structure of an air conditioner is demonstrated using FIG.1 and FIG.2. FIG. 1 is a configuration diagram of an air conditioner, and FIG. 2 is a side sectional view of the indoor unit.
図1は空気調和機の全体構成図である。空気調和機1は、室内機2,室外機3、及び室内機2に操作信号を送信するリモコン12を備える。室内機2及び室外機3は接続管5で接続される。室内機2は、筐体9内に、後述する熱交換器16等の内部構造体を備える。空気調和機1は、室内空気を空気吸込口6から吸い込み、熱交換器16で加熱,冷却,除湿等された室内空気を空気吹出口13から室内に吹き出すことにより、室内を空気調和する。   FIG. 1 is an overall configuration diagram of an air conditioner. The air conditioner 1 includes an indoor unit 2, an outdoor unit 3, and a remote controller 12 that transmits an operation signal to the indoor unit 2. The indoor unit 2 and the outdoor unit 3 are connected by a connection pipe 5. The indoor unit 2 includes an internal structure such as a heat exchanger 16 described later in a housing 9. The air conditioner 1 air-conditions the room by sucking room air from the air suction port 6 and blowing the room air heated, cooled, and dehumidified by the heat exchanger 16 into the room from the air outlet 13.
図2は室内機の側断面図である。室内機2は、室内空気を吸い込む空気吸込口6を室内機2上面及び前面に備える。空気吸込口6の下流側には、室内空気中の塵埃を除去するフィルタ15が空気吸込口6を覆うように配置される。フィルタ15の下流であって、筐体9の中央部には、略逆V字状に形成され熱交換器16が配置される。熱交換器16の下流側には、熱交換器16の幅と略等しい長さの貫流ファン方式の送風ファン14が配置される。熱交換器16の下端部には露受皿17が配置される。露受皿17は冷房運転時や除湿運転時に熱交換器16に発生する凝縮水を受ける。露受皿17に集められた凝縮水はドレン配管を通して室外に排出される。熱交換器16の下流であって、室内機2の下部には、熱交換器16で加熱,冷却,除湿等された室内空気を室内に吹き出す空気吹出口13を備える。空気吹出口13には、吹き出される空気を左右方向に偏向する左右風向板19、及び、上下方向に偏向する上下風向板18を備える。   FIG. 2 is a side sectional view of the indoor unit. The indoor unit 2 includes air intake ports 6 for sucking room air on the upper surface and the front surface of the indoor unit 2. A filter 15 that removes dust in the room air is disposed on the downstream side of the air suction port 6 so as to cover the air suction port 6. Downstream of the filter 15 and in the central portion of the housing 9, a heat exchanger 16 is disposed in a substantially inverted V shape. A cross-flow fan type blower fan 14 having a length substantially equal to the width of the heat exchanger 16 is disposed on the downstream side of the heat exchanger 16. A dew tray 17 is disposed at the lower end of the heat exchanger 16. The dew tray 17 receives condensed water generated in the heat exchanger 16 during cooling operation or dehumidifying operation. The condensed water collected in the dew tray 17 is discharged outside through the drain pipe. An air outlet 13 is provided downstream of the heat exchanger 16 and below the indoor unit 2 to blow indoor air heated, cooled, or dehumidified by the heat exchanger 16 into the room. The air outlet 13 includes a left / right wind direction plate 19 for deflecting the blown air in the left / right direction and an up / down wind direction plate 18 for deflecting the air in the vertical direction.
図2において、送風ファン14を作動することにより空気は白抜き矢印のように流れる。つまり、送風ファン14を運転することで、室内空気を空気吸込口6から室内機2内に吸い込む。その際、フィルタ15により空気中の塵埃が除去される。その後、室内機2内に吸い込まれた室内空気は、熱交換器16で加熱,冷却,除湿等されて、送風ファン14を介して、空気吹出口13から室内に吹き出される。空気吹出口13から室内に吹き出される調和された空気は、左右風向板19及び上下風向板18により、左右方向及び上下方向が偏向される。このようにして、室内空気を空気吸込口6から吸い込み、熱交換器14で加熱,冷却,除湿等された室内空気を空気吹出口13から室内に吹き出すことにより、室内を空気調和する。尚、送風ファン14の回転時には、送風ファン14を構成する羽根と空気との間で乱流渦が発生し騒音となる。その騒音は就寝時やTV鑑賞時の妨げになるため、騒音が抑制された静かな運転音の空気調和機が望まれる。   In FIG. 2, the air flows as shown by white arrows by operating the blower fan 14. That is, by operating the blower fan 14, room air is sucked into the indoor unit 2 from the air suction port 6. At that time, dust in the air is removed by the filter 15. Thereafter, the indoor air sucked into the indoor unit 2 is heated, cooled, dehumidified, and the like by the heat exchanger 16 and blown into the room from the air outlet 13 via the blower fan 14. The conditioned air blown into the room from the air outlet 13 is deflected in the left-right direction and the up-down direction by the left-right wind direction plate 19 and the up-down wind direction plate 18. In this way, room air is sucked from the air suction port 6, and the room air heated, cooled, dehumidified, etc. by the heat exchanger 14 is blown into the room from the air outlet 13, thereby air conditioning the room. When the blower fan 14 rotates, turbulent vortices are generated between the blades constituting the blower fan 14 and the air, resulting in noise. Since the noise hinders bedtime and TV viewing, an air conditioner with quiet operation noise with suppressed noise is desired.
室内機2が使用される室内空間では、台所で魚,肉を焼いたとき等の調理臭に含まれるアセトアルデヒド,居室内で飼育するペットからの尿に含まれるアンモニアのにおい,喫煙によるタバコ臭に含まれる酢酸等の生活臭様々な臭いが発生する。このため、活性炭やゼオライトなどの多孔質材を基材とした吸着材である波型コルゲート形状の脱臭フィルタ(図示せず)等が、フィルタ15の通過空気下流部に設置される。   In the indoor space where the indoor unit 2 is used, acetaldehyde contained in cooking odors when fish and meat are baked in the kitchen, odor of ammonia contained in urine from pets kept in the room, tobacco odor due to smoking Various smells of daily life such as acetic acid are generated. Therefore, a corrugated corrugated deodorizing filter (not shown) or the like, which is an adsorbent based on a porous material such as activated carbon or zeolite, is installed in the downstream portion of the air passing through the filter 15.
また、室内機2が使用される室内空間の空気中には、インフルエンザウイルス等のウイルスや菌,カビ類が浮遊する。これらのウイルスや菌,カビ類は、空気調和機内部で繁殖し内部が汚れてしまう場合がある。このため、これらのウイルスや菌,カビ類を殺菌,抑制するために紫外線ランプを室内機内部に搭載する手段が考えられている。ウイルスや菌を殺菌できる紫外線波長としては、ウイルスや菌の遺伝子情報を持つDNAの紫外光吸収帯260nm付近である254nmが最も効果的である。しかしその一方で、この紫外線により室内機2に使用される樹脂を劣化させてしまうおそれがあり、紫外線ランプ周囲には紫外光を遮断し樹脂劣化を抑制する手段が必要となる。また、紫外線ランプの作動により消費電力の増大ともなる。   In addition, viruses such as influenza virus, fungi, and fungi float in the air of the indoor space where the indoor unit 2 is used. These viruses, fungi, and molds may propagate inside the air conditioner and become dirty inside. For this reason, in order to sterilize and control these viruses, fungi, and molds, means for mounting an ultraviolet lamp inside the indoor unit has been considered. As the ultraviolet wavelength capable of sterilizing viruses and bacteria, 254 nm, which is near the ultraviolet absorption band of 260 nm of DNA having gene information of viruses and bacteria, is most effective. However, on the other hand, there is a possibility that the resin used for the indoor unit 2 may be deteriorated by the ultraviolet rays, and a means for blocking the ultraviolet light and suppressing the resin deterioration around the ultraviolet lamp is required. In addition, the power consumption increases due to the operation of the ultraviolet lamp.
このような問題を解決するための本発明のイオン風発生装置を備えた空気調和機について、図3−図5を用いて説明する。図3はイオン風発生装置の構成を示す図であり図5のA−A断面図、図4は金属針状電極及び対極金属板の取付斜視図、図5は金属針状電極及び対極金属板の取付側断面図である。   An air conditioner equipped with the ion wind generator of the present invention for solving such problems will be described with reference to FIGS. 3 is a cross-sectional view taken along the line AA of FIG. 5, FIG. 4 is a perspective view of the attachment of the metal needle electrode and counter electrode metal plate, and FIG. 5 is the metal needle electrode and counter electrode metal plate. FIG.
本発明の空気調和機1が備えるイオン風発生装置39は、高電圧発生装置30と、高電圧発生装置30の高電圧端子31から伸びる導電体32と、対極金属板25と、対極金属板25の流入空気上流側に配置された金属針状電極24とで構成される。金属針状電極24は、気流方向に沿うように配置され、先端部が気流方向下流側に位置する。また、金属針状電極24の先端部は、送風ファン14の下流側(図5において、前面ノーズ60の先端と背面ノーズを結ぶ線よりも下流側)に位置する。   The ion wind generator 39 provided in the air conditioner 1 of the present invention includes a high voltage generator 30, a conductor 32 extending from a high voltage terminal 31 of the high voltage generator 30, a counter electrode metal plate 25, and a counter electrode metal plate 25. And a metal needle electrode 24 arranged on the upstream side of the inflow air. The metal needle-like electrode 24 is disposed along the airflow direction, and the tip is located downstream in the airflow direction. The tip of the metal needle electrode 24 is located downstream of the blower fan 14 (downstream of the line connecting the tip of the front nose 60 and the back nose in FIG. 5).
高電圧発生装置30で発生させた−3kV〜−6kVの高電圧を金属針状電極24に印加することにより、金属針状電極24上で負コロナ放電が発生する。金属針状電極24上で負コロナ放電が発生すると、金属針状電極24から対地アースに接続された対極金属板25に向かって負イオンが流れ始めるとともに、イオン風26が発生する。発生したイオン風26は、送風ファン14からの気流を案内するケーシング部22の湾曲形状に合わせた対極金属板25に沿って室内空間に吹き出される。   By applying a high voltage of −3 kV to −6 kV generated by the high voltage generator 30 to the metal needle electrode 24, negative corona discharge is generated on the metal needle electrode 24. When negative corona discharge occurs on the metal needle electrode 24, negative ions begin to flow from the metal needle electrode 24 toward the counter electrode metal plate 25 connected to the ground, and an ion wind 26 is generated. The generated ion wind 26 is blown out into the indoor space along the counter electrode metal plate 25 matched with the curved shape of the casing portion 22 that guides the air flow from the blower fan 14.
この負イオンにより、空気中を浮遊するウイルスや菌,カビ類を殺菌,抑制することができる。また、このイオン風26は、高電圧の印加によって生成された負イオンと中性分子との衝突により、イオンの運動エネルギーが中性分子に与えられ、負イオンと中性分子が対極金属板25に向かう分子運動である。従って、イオン風26を発生させるための動作音が全くしないので、無音で使用空間に送風することができる。   These negative ions can sterilize and suppress viruses, fungi, and fungi floating in the air. Further, the ion wind 26 gives the kinetic energy of the ions to the neutral molecules due to the collision between the negative ions generated by the application of the high voltage and the neutral molecules, and the negative ions and the neutral molecules become the counter electrode metal plate 25. It is a molecular motion toward Therefore, since there is no operation sound for generating the ion wind 26, it is possible to blow air into the use space without sound.
このイオン風26は、送風ファン14の送風量に比べると非常に弱い。従って、金属針状電極24及び対極金属板25は、気流の吹き出し方向に抵抗となるものがない位置、つまり、送風ファン14の下流側(図5において、前面ノーズ60の先端と背面ノーズを結ぶ線62よりも下流側)で、より好ましくは、送風ファン14の背面側(送風ファン14の中心から水平方向背面側であって、送風ファン14とケーシング部22との間)に配置する。送風ファン14の上流側に金属針状電極24が位置する場合、送風ファン14を形成する羽根によってイオン風26が遮られてしまい、イオン風26を室内空間に広く送風することが難しい。   The ion wind 26 is very weak as compared with the air blowing amount of the blower fan 14. Accordingly, the metal needle electrode 24 and the counter electrode metal plate 25 are connected to a position where there is no resistance in the blowing direction of the airflow, that is, downstream of the blower fan 14 (in FIG. 5, the front nose 60 and the rear nose are connected to each other). More preferably, it is arranged on the back side of the blower fan 14 (on the downstream side of the line 62) (on the rear side in the horizontal direction from the center of the blower fan 14 and between the blower fan 14 and the casing portion 22). When the metal needle electrode 24 is located on the upstream side of the blower fan 14, the ion wind 26 is blocked by the blades forming the blower fan 14, and it is difficult to blow the ion wind 26 widely into the indoor space.
一方、対極金属板25を、ケーシング部22と重ね合わせて湾曲させることで、イオン風26を徐々に拡大させて室内空間に吹き出すことができる。特に、対極金属板25を金属針状電極24の先端部よりも下流側に位置させることにより、発生したイオン風をスムーズに空気吹出口13から室内に向けて吹き出すことができる。   On the other hand, when the counter electrode metal plate 25 is overlapped with the casing portion 22 and curved, the ion wind 26 can be gradually expanded and blown into the indoor space. In particular, by positioning the counter electrode metal plate 25 on the downstream side of the tip of the metal needle electrode 24, the generated ion wind can be smoothly blown out from the air outlet 13 into the room.
さらに、イオン風26を室内空間に吹き出すためには、湾曲したケーシング部22の円弧接線の延長線上と上下風向板18の上下角度を一致させることが好ましい。   Further, in order to blow the ion wind 26 into the indoor space, it is preferable that the vertical angle of the vertical wind direction plate 18 coincides with the extension of the arc tangent of the curved casing portion 22.
前述の通り、イオン風26は送風ファン14の送風量よりも弱く、熱交換器16を通過する風量が少ないため、イオン風26のみを用いた場合、熱交換器16における熱交換量が低下する。このため、空気調和機1の使用空間が設定温度に達した場合(空気調和機1の使用空間が設定温度以上となった場合)に、送風ファン14の回転を停止させ、金属針状電極24に高電圧を印加して、イオン風26を発生させる。このように制御することで、無音で室内空気を調和し、さらに送風ファンを回転させるための電力をカットすることで省エネ運転が可能となる。また、就寝時の快適性を向上させるために、就寝時モードとして送風ファン14を運転せずに、イオン風26のみで室内を空調するようにしてもよい。このようにしても同様に、無音で室内空気を調和し、さらに送風ファンを回転させるための電力をカットすることで省エネ運転が可能となる。   As described above, since the ion wind 26 is weaker than the air blowing amount of the blower fan 14 and the air volume passing through the heat exchanger 16 is small, the heat exchange amount in the heat exchanger 16 is reduced when only the ion wind 26 is used. . For this reason, when the use space of the air conditioner 1 reaches the set temperature (when the use space of the air conditioner 1 becomes equal to or higher than the set temperature), the rotation of the blower fan 14 is stopped and the metal needle-like electrode 24 is stopped. The ion wind 26 is generated by applying a high voltage to. By controlling in this way, the room air can be harmonized silently, and further, the power for rotating the blower fan can be cut to save energy. Moreover, in order to improve the comfort at the time of bedtime, you may make it air-condition the room only by the ion wind 26, without driving the ventilation fan 14 as a bedtime mode. Even if it does in this way, an energy-saving driving | operation becomes possible by cutting off the electric power for harmonizing indoor air silently and also rotating a ventilation fan similarly.
尚、イオン風26は、金属針状電極24の長さと本数に比例して増大するため、より多くのイオン風26を吹き出すために、送風ファン14の長手方向に沿って、対極金属板25のほぼ全幅に渡って複数本配置することが好ましい。   In addition, since the ion wind 26 increases in proportion to the length and the number of the metal needle-like electrodes 24, in order to blow out more ion winds 26, along the longitudinal direction of the blower fan 14, It is preferable to arrange a plurality of them over almost the entire width.
本実施例のような金属針状電極24及び対極金属板25を備えたイオン風発生装置により、発生した負イオンは空気中に吹き出され、空気中を漂う塵埃や菌,カビ,ウイルスに付着してマイナスに帯電し、対極の電位である対極金属板25に付着する。対極金属板25を金属イオンの溶出により抗菌効果が出現する金属とすることで、菌,カビ,ウイルスの増殖をさらに抑制でき、室内機2内部をさらに清潔に保つことができる。金属イオンで抗菌効果があるものとしては銀,銅,ニッケル等があるが、コストを抑制するためにはニッケルを含むオーステナイト系ステンレスとすることが好ましい。さらに、イオン風26の運転を続けることで、空気循環により室内空気の清浄化も可能となる。   With the ion wind generator provided with the metal needle electrode 24 and the counter electrode metal plate 25 as in the present embodiment, the generated negative ions are blown into the air and adhere to dust, fungi, mold, and viruses floating in the air. It is negatively charged and adheres to the counter electrode metal plate 25 having the counter electrode potential. By making the counter electrode metal plate 25 a metal that exhibits an antibacterial effect by elution of metal ions, the growth of fungi, molds, and viruses can be further suppressed, and the interior of the indoor unit 2 can be further kept clean. Examples of metal ions that have an antibacterial effect include silver, copper, and nickel. In order to reduce costs, austenitic stainless steel containing nickel is preferable. Furthermore, by continuing the operation of the ion wind 26, the indoor air can be purified by air circulation.
