Description

空調装置の室内機、空調システム及びイオン発生アセンブリIndoor unit of air conditioner, air conditioner system and ion generation assembly
　本発明は、空調装置の室内機、空調システム及びイオン発生アセンブリに関し、具体的には、イオン発生器が取り付けられた空調装置の室内機、該室内機を含む空調装置及びイオン発生アセンブリに関する。 The present invention relates to an indoor unit of an air conditioner, an air conditioner system, and an ion generation assembly, specifically, an indoor unit of an air conditioner to which an ion generator is attached, an air conditioner including the indoor unit, and an ion generation assembly.
　空気調節設備としての空調装置では、適用されるユーザグループの拡大化と生活品質の継続的な向上に伴い、ユーザグループの空調装置に対する需要は、空気の温度、湿度の調節だけでは満たされなくなっている。現在、室内空気の品質に起因する健康問題を意識し始めたユーザグループがますます多くなるため、室内空気の除菌と浄化への注目度も日々高まっている。 For air conditioners as air conditioning equipment, as the applicable user group expands and the quality of life continues to improve, the demand for air conditioners for user groups cannot be met by air temperature and humidity control alone. There is. Nowadays, as more and more user groups are beginning to be aware of health problems caused by the quality of indoor air, attention is being paid to sterilization and purification of indoor air every day.
　近年、室内空気の除菌、浄化及び脱臭などの問題を中心に様々な研究が行われていた。従来の空調室内機では、一般的には、活性炭などの物理吸着方式で殺菌、脱臭などを実現していたが、この方式には、主に３つの欠点がある。第一に、活性炭の寿命は短く、通常３ヶ月から６ヶ月で交換する必要があり、第二に、空調室内機内に活性炭を配置すると、風抵抗が大きくなり、風量に影響を与え、騒音を大きくし、有効電力を下げ、第三に、一般的には、活性炭は、室内機の還気口に取り付けられ、還気口の有効面積で吸着し、除菌脱臭の全体速度が遅くなる。 In recent years, various studies have been conducted focusing on issues such as sterilization, purification and deodorization of indoor air. In the conventional air-conditioning indoor unit, sterilization, deodorization, etc. are generally realized by a physical adsorption method such as activated carbon, but this method has three main drawbacks. First, the life of activated carbon is short, and it usually needs to be replaced in 3 to 6 months. Second, if activated carbon is placed inside the air-conditioning indoor unit, the wind resistance will increase, affecting the air volume and causing noise. Increased and reduced active power, thirdly, generally, activated carbon is attached to the return air port of the indoor unit and is adsorbed in the effective area of the return air port, slowing down the overall rate of sterilization and deodorization.
　それに対して、従来の空調装置の室内機では、室内機本体の内部にイオン発生器を配置する技術が用いられ、イオン発生器の放電電極が放電することで負イオンを発生させ、細菌ウイルスに負イオンを吸着させ、細菌やウイルスのタンパク質構造を破壊し、さらに殺菌脱臭の機能を実現する。 On the other hand, in the indoor unit of the conventional air conditioner, a technique of arranging an ion generator inside the main body of the indoor unit is used, and the discharge electrode of the ion generator discharges to generate negative ions, which becomes a bacterial virus. It adsorbs negative ions, destroys the protein structure of bacteria and viruses, and realizes the function of sterilization and deodorization.
　しかしながら、従来の空調装置の室内機では、イオン発生器は、室内機本体の内壁面に取り付けられたため、イオン発生器を交換する必要がある場合は、装飾パネルを取り外してから、交換すべきイオン発生器を室内機本体の内壁面から取り外さなければならないため、交換作業全体が煩雑になる。ひいては、イオン発生器の接続構造が比較的に複雑なので、古いイオン発生器を取り外せるようにするには、装飾パネルを取り外す必要があるほか、室内機本体の筐体や送気機ケースを取り外す必要もある。 However, in the indoor unit of the conventional air conditioner, the ion generator is attached to the inner wall surface of the indoor unit body, so if it is necessary to replace the ion generator, the decorative panel should be removed and then the ion should be replaced. Since the generator must be removed from the inner wall surface of the indoor unit body, the entire replacement work becomes complicated. As a result, the connection structure of the ion generator is relatively complicated, so in order to be able to remove the old ion generator, it is necessary to remove the decorative panel, as well as the housing of the indoor unit and the air blower case. There is also.
　一方、イオン発生器は、室内機本体の内壁面に排出口から距離があるように取り付けられたため、帯電イオンが調和空気とともに吹き出される過程で、帯電イオンが室内機本体の筐体や導風羽根機構などの金属製部材に吸着されやすくなることで、殺菌脱臭の効果が大幅に低下する。 On the other hand, since the ion generator is attached to the inner wall surface of the indoor unit body at a distance from the discharge port, the charged ions are blown out together with the conditioned air, and the charged ions are discharged to the housing of the indoor unit body and the air guide. The effect of sterilization and deodorization is significantly reduced because it is easily adsorbed by metal members such as the blade mechanism.
　本発明は、従来の技術に存在している上述した技術課題に鑑みてなされたものであり、イオン発生器の交換作業が簡便で、且つ、イオン発生器の殺菌脱臭効果を良好に維持できる、イオン発生器が取り付けられた空調装置の室内機、該室内機を含む空調装置及びイオン発生アセンブリを提供することを目的とする。 The present invention has been made in view of the above-mentioned technical problems existing in the prior art, the replacement work of the ion generator is easy, and the sterilizing and deodorizing effect of the ion generator can be well maintained. It is an object of the present invention to provide an indoor unit of an air conditioner to which an ion generator is attached, an air conditioner including the indoor unit, and an ion generation assembly.
　本発明の第一観点に係る空調装置の室内機は、室内機本体と前記室内機本体の室内空間に向かう側に配置された装飾パネルとを含む空調装置の室内機であって、前記装飾パネルに前記室内空間へ気流を吹出すための少なくとも１つの排出口が形成され、前記装飾パネルに室内空気を殺菌する帯電イオンを発生可能なイオン発生器が取り付けられ、前記イオン発生器は、帯電イオンを発生させるイオン発生部を含み、前記イオン発生器は、前記装飾パネルの隅部に取り付けられることで、前記イオン発生部から発生した帯電イオンを前記排出口から吹き出された気流に接触させる。 The indoor unit of the air conditioner according to the first aspect of the present invention is the indoor unit of the air conditioner including the indoor unit main body and the decorative panel arranged on the side of the indoor unit main body facing the indoor space, and the decorative panel. At least one outlet for blowing airflow into the indoor space is formed in the room, and an ion generator capable of generating charged ions that sterilize the indoor air is attached to the decorative panel. The ion generator is attached to a corner of the decorative panel so as to bring the charged ions generated from the ion generating portion into contact with the air flow blown out from the discharge port.
　本発明の第一観点に記載の室内機によれば、イオン発生器が室内機の装飾パネルに取り付けられたため、イオン発生器の交換作業を行うときに、機器本体を分解したり、機器本体内部の狭い空間に入ったりする作業は不要で、装飾パネルを取り外すだけでよく、作業効率が高い。また、イオン発生器が装飾パネルに取り付けられたため、イオン発生器が室内機本体の内壁面に取り付けられたことに起因する、帯電イオンが、例えば金属製の室内機本体の筐体や導風羽根機構に吸着されて失効する状況を回避でき、帯電イオンの利用率を高めることができる。さらに、イオン発生器は、装飾パネルの排出口に近いため、空気が排出口から吹き出されると、帯電イオンが吹き出された空気に直接接触することで、吹き出された空気を浄化することができるとともに、吹き出された空気とともに室内空間に拡散して室内空気を浄化することができる。また、利用可能な空間が狭い辺部部分よりも、装飾パネルの隅部部分の利用可能な空間が広く、イオン発生器を装飾パネルの隅部に取り付けることで、装飾パネルの空き空間を効果的に利用することができる。さらに、イオン発生器を装飾パネルの辺部に取り付けると、天井及び装飾パネルに穴を開ける必要があるため、漏風及び装飾パネルの周縁の強度低下を招く恐れがある。それに対して、本願において、イオン発生器を装飾パネルの隅部に取り付けることで、上記のような状況が発生することを回避することができる。 According to the indoor unit described in the first aspect of the present invention, since the ion generator is attached to the decorative panel of the indoor unit, the device main body may be disassembled or the inside of the device main body may be disassembled when the ion generator is replaced. There is no need to enter the narrow space of the room, just remove the decorative panel, and the work efficiency is high. Further, since the ion generator is attached to the decorative panel, the charged ions caused by the ion generator being attached to the inner wall surface of the indoor unit body are, for example, the metal housing of the indoor unit body and the air guide blade. It is possible to avoid the situation where it is adsorbed by the mechanism and expires, and it is possible to increase the utilization rate of charged ions. Furthermore, since the ion generator is close to the outlet of the decorative panel, when air is blown out from the outlet, the charged ions come into direct contact with the blown air to purify the blown air. At the same time, it is possible to purify the indoor air by diffusing into the indoor space together with the blown air. In addition, the available space at the corners of the decorative panel is wider than the narrow sides, and by attaching the ion generator to the corners of the decorative panel, the empty space of the decorative panel is effective. Can be used for. Further, if the ion generator is attached to the side of the decorative panel, it is necessary to make a hole in the ceiling and the decorative panel, which may lead to air leakage and a decrease in the strength of the peripheral edge of the decorative panel. On the other hand, in the present application, by attaching the ion generator to the corner of the decorative panel, it is possible to avoid the above situation.

By mounting an ion generator in the vicinity of at least one corner of the decorative panel near one outlet, charged ions can be diffused into the interior space together with the air blown from the first outlet. Since the first outlet usually has a large air volume, it is more advantageous for charged ions to diffuse into the indoor space. Further, by attaching the ion generator to the corner space not located in the airflow path, the life of the ion generator can be improved.
　本発明の第三観点に係る空調装置の室内機は、本発明の第一観点に記載の空調装置の室内機において、好ましくは、前記装飾パネルの少なくとも１つの隅部に前記排出口としての第二排出口が配置され、前記装飾パネルの前記第二排出口が配置された少なくとも１つの隅部に少なくとも１つの前記イオン発生器が取り付けられる。 The indoor unit of the air conditioner according to the third aspect of the present invention is preferably the indoor unit of the air conditioner according to the first aspect of the present invention, preferably at least one corner of the decorative panel as the outlet.

In addition, the work of attaching and detaching the ion generator is more convenient. Moreover, normally, the suction port is provided at a position inside the discharge port of the decorative panel, but if the ion generator is provided inside the second discharge port, the ion generator is brought closer to the suction port. Therefore, a part of the generated charged ions may be caught in the inside of the indoor unit body by the intake air flow and may not function.

3 is a perspective view showing the ion generation assembly 4, FIG. 4 is an exploded perspective view of the ion generation assembly 4 of FIG. 3, and FIG. 5 is a cross-sectional view of the ion generation assembly 4. As can be seen by combining FIGS. 3 and 4, the ion generation assembly 4 includes a corner decorative plate 41 and an ion generator G arranged on the corner decorative plate 41. The corner decorative plate 41 is made by, for example, injection molding, and has a lower surface 411, an upper surface 412, and a plurality of plate side portions 413 to 417. Further, by the above-mentioned processing, a part of the corner decorative plate 41 close to the plate side portion 413 is recessed downward to be formed in the storage portion 42 for accommodating the ion generator G, and the corner decoration is provided here. The storage portion 42 was formed with a notch in the vertical direction with respect to the non-protruding portion of the plate 41, and the notch was closed by the wall portion 43 having a grid-like opening O. Regarding the storage form in which the storage unit 42 stores the ion generator G, specifically, as shown in FIGS. 4 and 5, a storage space 44 recessed downward is formed in the storage unit 42, and the ion generator G is provided.

It surrounds 45 and closes the storage space 44.
　本例において、イオン発生アセンブリ４の収納空間４４の境界に２枚のバッフル板４５が立設されているが、それに限らず、バッフル板４５を設けずに、イオン発生器Ｇを収納空間４４に置いた後で、該収納空間４４の上方に発生器ケースＧ２を直接固定して前記イオン発生器Ｇを被覆するようにしてもよい。 In this example, two baffle plates 45 are erected at the boundary of the storage space 44 of the ion generation assembly 4, but the present invention is not limited to this, and the ion generator G is placed in the storage space 44 without providing the baffle plate 45. After placing, the generator case G2 may be directly fixed above the storage space 44 to cover the ion generator G.
　さらに、本例において、隅部装飾板４１の板辺部４１３に近い部分に室内空間側へ窪む収納部４２が形成されるとともに、該収納部４２でイオン発生器Ｇを収納するが、それに限らない。例えば、隅部装飾板４１は、平板でもよく、イオン発生器Ｇを該隅部装飾パネル４１の上面４１２に取り付けるとともに、該隅部装飾パネル４１のイオン発生器Ｇのイオン発生部Ｇ１に対向する部分に開口を形成することで、同じ技術効果を実現することもできる。 Further, in this example, a storage portion 42 recessed toward the interior space side is formed in a portion close to the plate side portion 413 of the corner decorative plate 41, and the ion generator G is stored in the storage portion 42. Not exclusively. For example, the corner decorative plate 41 may be a flat plate, and the ion generator G is attached to the upper surface 412 of the corner decorative panel 41 and faces the ion generating portion G1 of the ion generator G of the corner decorative panel 41. The same technical effect can be achieved by forming an opening in the portion.
　（イオン発生器Ｇの組成及び構造）
　図５は、図３のイオン発生アセンブリ４の断面図を示し、該イオン発生アセンブリ４の収納空間４４に収納されたイオン発生器Ｇを示す。図５に示すように、イオン発生器Ｇは、イオン発生部Ｇ１と、発生器ケースＧ２と、高圧電源部Ｇ３とを含み、ここに、イオン発生部Ｇ１は、隅部装飾板４１の上面４１２に固定され、該イオン発生部Ｇ１の壁部４３の開口Ｏに近い一端に放電電極（不図示）が形成され、該放電電極は、上述開口Ｏに対面して近づくことで、イオン発生部Ｇ１から発生した帯電イオンを開口Ｏから流出させることができ、該イオン発生部Ｇ１の他端に導線が形成され、該導線により、イオン発生部Ｇ１が高圧電源部Ｇ３と電気的に接続された。図５に示すように、高圧電源部Ｇ３は、イオン発生部Ｇ１の後側に配置され、放電電極を空気へ放電させて帯電イオンを形成させるように、導線で該イオン発生部Ｇ１に電源を供給する。さらに、上記したように、発生器ケースＧ２は、上方からボルト接続などの形態により収納空間４４を被覆しイオン発生部Ｇ１と高圧電源部Ｇ３を外部から隔離させる。 (Composition and structure of ion generator G)
FIG. 5 shows a cross-sectional view of the ion generation assembly 4 of FIG. 3 and shows an ion generator G housed in the storage space 44 of the ion generation assembly 4. As shown in FIG. 5, the ion generator G includes an ion generator G1, a generator case G2, and a high-pressure power supply unit G3, wherein the ion generator G1 includes an upper surface 412 of a corner decorative plate 41. A discharge electrode (not shown) is formed at one end of the wall portion 43 of the ion generating portion G1 near the opening O, and the discharge electrode approaches the opening O so as to face the opening O, whereby the ion generating portion G1 The charged ions generated from the above can be discharged from the opening O, a lead wire is formed at the other end of the ion generating section G1, and the ion generating section G1 is electrically connected to the high pressure power supply section G3 by the lead wire. As shown in FIG. 5, the high-voltage power supply unit G3 is arranged behind the ion generation unit G1 and supplies power to the ion generation unit G1 with a conducting wire so as to discharge the discharge electrode to the air to form charged ions. Supply. Further, as described above, the generator case G2 covers the storage space 44 from above in the form of a bolt connection or the like, and separates the ion generation unit G1 and the high voltage power supply unit G3 from the outside.
　（イオン発生アセンブリ４の配置形態）
　次に、図６を参照し、イオン発生アセンブリ４が該装飾パネル３の隅部３０ｅに取り付けられた状態を説明する。 (Arrangement form of ion generation assembly 4)
Next, with reference to FIG. 6, the state in which the ion generation assembly 4 is attached to the corner portion 30e of the decorative panel 3 will be described.
　図６に示すように、イオン発生アセンブリ４が装飾パネル３の隅部３０ｅに取り付けられた場合に、該イオン発生アセンブリ４の開口Ｏが形成された壁部４３は、装飾パネル３の位置する平面に対して傾斜することで、イオン発生部Ｇ１から発生した帯電イオンを該イオン発生アセンブリ４の出口Ｏから斜め下向きの方向に沿って流出させる。具体的には、本例において、壁部４３は、平面Ｐに対して第二排出口３１ｅから離れる方向に向かって傾斜するように構成されることで、該壁部４３の位置する平面が第二排出口３１ｅから吹き出された気流の流動方向と平行になり、ここに、平面Ｐは、水平面（もし装飾パネルが平面状であれば、装飾パネル３の位置する平面を指す）と直交する平面である。例えば、第二排出口３１ｅから吹き出された気流の流動方向と平面Ｐとの間の角度が５０°の場合に、壁部４３の平面Ｐに対して該第二排出口３１ｅから離れる方向に向かって傾斜する傾斜角度αも５０°である。これにより、室内空気が装飾パネル３の吸入口３１から室内機本体２に吸い込まれるとともに、熱交換器を流れて冷媒と熱交換された後で、第一排出口３１ａを介して吹き出された場合に、出口Ｏから流出した帯電イオンは、吹き出された気流に直接接触し、その結果、帯電イオンは第二吹出口３１ｅから吹き出された気流に伴って室内空間に拡散されることで、室内空間内に存在する菌類を死滅させる。 As shown in FIG. 6, when the ion generating assembly 4 is attached to the corner portion 30e of the decorative panel 3, the wall portion 43 in which the opening O of the ion generating assembly 4 is formed is a flat surface on which the decorative panel 3 is located. By inclining with respect to the above, charged ions generated from the ion generation unit G1 are discharged from the outlet O of the ion generation assembly 4 in a diagonally downward direction. Specifically, in this example, the wall portion 43 is configured to be inclined toward the plane P in a direction away from the second discharge port 31e, so that the plane on which the wall portion 43 is located is the second. (Ii) The plane P is parallel to the flow direction of the airflow blown out from the discharge port 31e, and the plane P is a plane orthogonal to the horizontal plane (if the decorative panel is flat, it refers to the plane on which the decorative panel 3 is located). Is. For example, when the angle between the flow direction of the airflow blown out from the second discharge port 31e and the plane P is 50 °, the direction away from the second discharge port 31e with respect to the plane P of the wall portion 43 is directed. The tilt angle α for tilting is also 50 °. As a result, when the indoor air is sucked into the indoor unit main body 2 from the suction port 31 of the decorative panel 3, and after flowing through the heat exchanger and exchanging heat with the refrigerant, it is blown out through the first discharge port 31a. In addition, the charged ions flowing out from the outlet O come into direct contact with the blown airflow, and as a result, the charged ions are diffused into the indoor space along with the airflow blown out from the second outlet 31e, thereby causing the indoor space. Kill the fungi that exist inside.
　本例において、壁部４３は、その存在する平面が第二排出口３１ｅから吹き出された気流の流動方向と平行に設けられるが、それに限らない。例えば、壁部４３は、その位置する平面が装飾パネル３の位置する平面に垂直に設けられてもよく、その位置する平面が第二排出口３１ｅから吹き出された気流の流動方向よりも該第二排出口３１ｅに近い方向に傾斜するように設けられてもよく、つまり、もし第二排出口３１ｅから吹き出された気流の流動方向が平面Ｐとの間の角度が５０°の場合に、該壁部４３の位置する平面が平面Ｐに対して第二排出口３１ｅから離れる方向に傾斜する傾斜角度α≦５０°であり、好ましくは、αは、４５°である。 In this example, the wall portion 43 is provided with its existing plane parallel to the flow direction of the airflow blown out from the second discharge port 31e, but is not limited to this. For example, the wall portion 43 may be provided with a plane on which the wall portion 43 is located perpendicular to the plane on which the decorative panel 3 is located, and the plane on which the wall portion 43 is located is the first in the flow direction of the airflow blown from the second discharge port 31e. (Ii) It may be provided so as to be inclined in a direction close to the discharge port 31e, that is, if the flow direction of the airflow blown from the second discharge port 31e is at an angle of 50 ° with the plane P, the said. The inclination angle α ≦ 50 ° at which the plane on which the wall portion 43 is located is inclined in a direction away from the second discharge port 31e with respect to the plane P, preferably α is 45 °.
　（第一実施形態の効果）
　上述した構造を有する室内機１により、装飾パネル３の隅部３０ｅ、３０ｆ、３０ｇ、３０ｈの利用可能な空間が辺部３０ａ、３０ｂ、３０ｃ、３０ｄの利用可能な空間よりも広いため、イオン発生器Ｇを装飾パネル３の隅部３０ａに取り付けることで、装飾パネル３的利用可能な空間を十分に利用することができ、操作性が大きい。 (Effect of the first embodiment)
Due to the indoor unit 1 having the above-mentioned structure, the available space of the corners 30e, 30f, 30g, 30h of the decorative panel 3 is wider than the available space of the side portions 30a, 30b, 30c, 30d, so that ions are generated. By attaching the vessel G to the corner portion 30a of the decorative panel 3, the space that can be used as the decorative panel 3 can be fully utilized, and the operability is high.
　さらに、装飾パネル３の第二排出口３１ｅに近い隅部３０ｅにイオン発生器Ｇを含むイオン発生アセンブリ４を取り付けることで、イオン発生器Ｇを装飾パネル３の隅部３１ｅの上面（正確には、該装飾パネル３の隅部３１ｅを構成するイオン発生アセンブリ４の隅部装飾板４１の上面）に取り付け、該イオン発生器Ｇにより発生した帯電イオンをイオン発生アセンブリ４に形成された開口Ｏを介して流出させるとともに、第二排出口３１ｅから吹き出された空気と伴って室内空間に拡散させることによって、室内空間に存在するウイルス、細菌を死滅させる。 Further, by attaching the ion generation assembly 4 including the ion generator G to the corner portion 30e near the second discharge port 31e of the decorative panel 3, the ion generator G can be attached to the upper surface of the corner portion 31e of the decorative panel 3 (to be exact). , The upper surface of the corner decorative plate 41 of the ion generation assembly 4 constituting the corner portion 31e of the decorative panel 3), and the charged ions generated by the ion generator G are transferred to the opening O formed in the ion generation assembly 4. It is discharged through the air, and diffused into the indoor space together with the air blown from the second discharge port 31e to kill the viruses and bacteria existing in the indoor space.
　また、イオン発生器Ｇは、装飾パネル３の上面（即ち、室内機本体に向かう側）に取り付けられたため、イオン発生器Ｇを室内機１の内側に隠すことができ、室内機１の見栄え及び安全性を向上させることができる。 Further, since the ion generator G is attached to the upper surface of the decorative panel 3 (that is, the side facing the indoor unit main body), the ion generator G can be hidden inside the indoor unit 1, and the appearance of the indoor unit 1 can be improved. Safety can be improved.
　なお、イオン発生器Ｇが室内機１の装飾パネル３に取り付けられたため、イオン発生器Ｇの交換作業を行うときに、機器本体を分解したり、機器本体内部の狭い空間に入ったりする作業は不要で、装飾パネルを取り外すだけでよく、作業効率が高い。 Since the ion generator G is attached to the decorative panel 3 of the indoor unit 1, when the ion generator G is replaced, the work of disassembling the device body or entering the narrow space inside the device body is not possible. It is unnecessary, just remove the decorative panel, and the work efficiency is high.
　また、イオン発生器Ｇがイオン発生アセンブリ４の上面に配置されるとともに、該イオン発生アセンブリ４により形成された収納空間４４内に位置するため、イオン発生器Ｇの配線が第一排出口３１ａ、３１ｂ、３１ｃ、３１ｄ及び第二排出口３１ｅ、３１ｆ、３１ｇ、３１ｈを避けることができ、イオン発生器Ｇの電線が長期間にわたって冷風や熱風の環境に曝されて劣化することによる、イオン発生器Ｇが故障することを防止することができる。 Further, since the ion generator G is arranged on the upper surface of the ion generation assembly 4 and is located in the storage space 44 formed by the ion generation assembly 4, the wiring of the ion generator G is arranged in the first discharge port 31a. 31b, 31c, 31d and the second discharge ports 31e, 31f, 31g, 31h can be avoided, and the electric wire of the ion generator G is exposed to the environment of cold air or hot air for a long period of time and deteriorates. It is possible to prevent G from failing.
　さらに、イオン発生器Ｇが発生器ケースＧ２を有するため、発生器ケースＧ２をイオン発生アセンブリ４に接続してイオン発生器Ｇのイオン発生部Ｇ１及び高圧電源部Ｇ３を外部から隔離させることで、外部環境から影響を受けないように該イオン発生部Ｇ１及び高圧電源部Ｇ３を保護することができる。 Further, since the ion generator G has the generator case G2, the generator case G2 is connected to the ion generation assembly 4 to isolate the ion generator G1 and the high voltage power supply unit G3 of the ion generator G from the outside. The ion generation unit G1 and the high voltage power supply unit G3 can be protected so as not to be affected by the external environment.
　さらに、イオン発生器Ｇが装飾パネル３の隅部３０ｅに取り付けられるとともに、イオン発生アセンブリ４の帯電イオンが流出する開口Ｏが第二排出口３１ｅから吹き出された気流の流動経路に対面するため、イオン発生器Ｇを室内機本体２の内部に取り付けた場合よりも、帯電イオンが吹き出された空気に伴って室内機本体２から装飾パネル３の第二排出口３１ｅへ流動する過程で金属製の室内機本体２の筐体または装飾パネル３に吸着されたことを避けることができ、帯電イオンの利用率を高めることができる。 Further, since the ion generator G is attached to the corner portion 30e of the decorative panel 3 and the opening O through which the charged ions of the ion generation assembly 4 flow out faces the flow path of the air flow blown out from the second discharge port 31e. Compared to the case where the ion generator G is attached inside the indoor unit main body 2, it is made of metal in the process of flowing charged ions from the indoor unit main body 2 to the second discharge port 31e of the decorative panel 3 along with the blown air. It is possible to avoid being adsorbed on the housing of the indoor unit main body 2 or the decorative panel 3, and it is possible to increase the utilization rate of charged ions.
　（第一実施形態の変形例）
　第一実施形態において、第二排出口３１ｅに近い隅部３０ｅに１つのイオン発生器Ｇが設けられたことを例に説明したが、それに限らない。例えば、該隅部３０ｅに複数のイオン発生器Ｇを設けるとともに、複数のイオン発生器Ｇをイオン発生アセンブリ４の上面に共通に配置してもよい。さらに、装飾パネル３の各第二排出口３１ｅ、３１ｆ、３１ｇ、３１ｈに近い各隅部３０ｅ、３０ｆ、３０ｇ、３０ｈに１つ以上のイオン発生器Ｇをそれぞれ取り付けてもよい。 (Modified example of the first embodiment)
In the first embodiment, it has been described as an example that one ion generator G is provided in the corner portion 30e near the second discharge port 31e, but the present invention is not limited to this. For example, a plurality of ion generators G may be provided in the corner portion 30e, and the plurality of ion generators G may be commonly arranged on the upper surface of the ion generation assembly 4. Further, one or more ion generators G may be attached to the corners 30e, 30f, 30g, 30h near the second discharge ports 31e, 31f, 31g, 31h of the decorative panel 3, respectively.
　一方、第一実施形態において、イオン発生アセンブリ４に形成された格子状の開口Ｏの角度は、一定であるが、該格子状の開口Ｏを角度調整可能に設けることで、該開口Ｏから流出した帯電イオンの流動方向を変えてもよい。 On the other hand, in the first embodiment, the angle of the lattice-shaped opening O formed in the ion generation assembly 4 is constant, but by providing the lattice-shaped opening O so that the angle can be adjusted, it flows out from the opening O. The flow direction of the charged ions may be changed.
　さらに、第一実施形態において、イオン発生器Ｇをイオン発生アセンブリ４に取り付けるとともに、該イオン発生アセンブリ４を装飾パネル３の隅部３０ｅに配置することで、イオン発生器Ｇを装飾パネル３の上面に取り付けるが、イオン発生器Ｇの取付形態について、それに限らない。例えば、図７に示すように、第一実施形態に記載のイオン発生アセンブリ４を設けずに、イオン発生器Ｇを装飾パネル３の隅部の下面に直接取り付けてもよい。図７に示すように、イオン発生器Ｇは、該イオン発生器Ｇの発生器ケースＧ２を介して装飾パネル３の隅部３０ｅの下面に取り付けられるとともに、該発生器ケースＧ２の第二排出口３１ｅに近い面に帯電イオンが流出するイオン流出口Ｍが形成された。図７によりわかるように、本例において、発生器ケースＧ２の第二排出口３１ｅに近い面は、装飾パネル３の位置する平面に垂直（または、略垂直）である。これにより、第一実施形態と基本的に同じ技術効果を得ることができ、且つ、取付がさらに便利であり、室内機装置パネルを変更する必要がなく、コストがさらに低い。 Further, in the first embodiment, the ion generator G is attached to the ion generation assembly 4, and the ion generation assembly 4 is arranged at the corner portion 30e of the decorative panel 3, so that the ion generator G is placed on the upper surface of the decorative panel 3. However, the mounting form of the ion generator G is not limited to that. For example, as shown in FIG. 7, the ion generator G may be directly attached to the lower surface of the corner of the decorative panel 3 without providing the ion generation assembly 4 described in the first embodiment. As shown in FIG. 7, the ion generator G is attached to the lower surface of the corner portion 30e of the decorative panel 3 via the generator case G2 of the ion generator G, and the second discharge port of the generator case G2. An ion outlet M through which charged ions flow out was formed on a surface close to 31e. As can be seen from FIG. 7, in this example, the surface of the generator case G2 near the second discharge port 31e is perpendicular to (or substantially perpendicular to) the plane on which the decorative panel 3 is located. As a result, basically the same technical effect as that of the first embodiment can be obtained, the mounting is more convenient, the indoor unit device panel does not need to be changed, and the cost is further reduced.
　さらに、第一実施形態において、室内機１は、隅部３０ｅ、３０ｆ、３０ｇ、３０ｈに位置する第二排出口３１ｅ、３１ｆ、３１ｇ、３１ｈ及び辺部３０ａ、３０ｂ、３０ｃ、３０ｄに位置する第一排出口３１ａ、３１ｂ、３１ｃ、３１ｄを同時に有する全周送気式室内機であるものを例に説明したが、それに限らない。例えば、室内機１は、片側送気式室内機、両側送気式室内機または四側送気式室内機でもよい。図８は、イオン発生器を片側送気式室内機に取り付けられた場合を示す。図８において、各室内機１Ａに、辺部に位置する第一排出口のみが設けられ、該第一排出口に水平導風板が設けられた。 Further, in the first embodiment, the indoor unit 1 is located at the second discharge ports 31e, 31f, 31g, 31h and the side portions 30a, 30b, 30c, 30d located at the corners 30e, 30f, 30g, 30h. Although the all-around air supply type indoor unit having one discharge port 31a, 31b, 31c, and 31d at the same time has been described as an example, the present invention is not limited thereto. For example, the indoor unit 1 may be a one-sided air supply type indoor unit, a two-sided air supply type indoor unit, or a four-sided air supply type indoor unit. FIG. 8 shows a case where the ion generator is attached to a one-sided air supply type indoor unit. In FIG. 8, each indoor unit 1A is provided with only a first discharge port located at a side portion, and a horizontal baffle plate is provided at the first discharge port.
　理解しやすいために、以下、図８における片側室内機１Ａを例に、装飾パネル３Ａの隅部３０Ａａにイオン発生アセンブリ４またはイオン発生器Ｇが取り付けられた具体的な位置を説明する。ここで、イオン発生アセンブリ４またはイオン発生器Ｇの具体的な取付位置を明確に説明するために、図中の一部の部材のサイズを誇張しており、実際のサイズを表すものではないことについて特に説明しなければならない。 For the sake of easy understanding, the specific position where the ion generation assembly 4 or the ion generator G is attached to the corner portion 30Aa of the decorative panel 3A will be described below by taking the one-sided indoor unit 1A in FIG. 8 as an example. Here, in order to clearly explain the specific mounting position of the ion generation assembly 4 or the ion generator G, the sizes of some members in the figure are exaggerated and do not represent the actual size. Must be specifically explained.
　図８に示すように、室内機１Ａは、装飾パネル３Ａを有する片側式室内機１Ａであり、該装飾パネル３Ａの二本の辺部３０Ａａと３０Ａｂに、辺部３０Ａｂの長さ方向に沿って延びる吸入口３１Ａと辺部３０Ａａの長さ方向に沿って延びる排出口３１Ａａがそれぞれ形成され、排出口３１Ａａに気流の風向を調節する水平導風板３２Ａａが配置された。該排出口３１Ａａに水平導風板３２Ａａが配置されたため、正面視において、該排出口３１Ａａは、導風板部Ａと導風板部Ａの反対側に位置する排出部Ｂとに区画されたと考えられる。さらに、排出口３１Ａａの端部の両側に位置する隅部３０Ａｃ、３０Ａｄにおける１つの隅部３１Ａｃに第一実施形態に記載のイオン発生アセンブリ４が取り付けられるか、または、イオン発生器Ｇが直接取り付けられる。ここに、イオン発生アセンブリ４が取り付けられた場合に、イオン発生アセンブリ４は、該イオン発生アセンブリ４に形成された出口Ｏが該排出口３１Ａａの排出部Ｂに近い位置に位置するように取り付けられ、イオン発生器Ｇが直接取り付けられた場合に、該イオン発生器Ｇは、該イオン発生器Ｇの発生器ケースＧ２に形成されたイオン流出口Ｍが該排出口３１Ａａの排出部Ｂに近づくように取り付けられる。 As shown in FIG. 8, the indoor unit 1A is a one-sided indoor unit 1A having a decorative panel 3A, and is formed on two side portions 30Aa and 30Ab of the decorative panel 3A along the length direction of the side portions 30Ab. An extending suction port 31A and an discharging port 31Aa extending along the length direction of the side portion 30Aa are formed, respectively, and a horizontal baffle plate 32Aa for adjusting the wind direction of the air flow is arranged at the discharging port 31Aa. Since the horizontal baffle plate 32Aa is arranged in the discharge port 31Aa, it is said that the discharge port 31Aa is divided into a baffle plate portion A and a discharge portion B located on the opposite side of the baffle plate portion A in the front view. Conceivable. Further, the ion generation assembly 4 according to the first embodiment is attached to one corner 31Ac at the corners 30Ac and 30Ad located on both sides of the end of the discharge port 31Aa, or the ion generator G is directly attached. Be done. When the ion generation assembly 4 is attached here, the ion generation assembly 4 is attached so that the outlet O formed in the ion generation assembly 4 is located at a position close to the discharge portion B of the discharge port 31Aa. When the ion generator G is directly attached, the ion generator G causes the ion outlet M formed in the generator case G2 of the ion generator G to approach the discharge portion B of the discharge port 31Aa. Can be attached to.
　上述した構造により、イオン発生アセンブリ４を該イオン発生アセンブリ４の出口Ｏが排出口３１Ａａの導風板部Ａと反対側にある排出部Ｂに近い位置に位置するように取り付けるか、イオン発生器Ｇを発生器ケースＧ２のイオン流出口Ｍが排出口３１Ａａの導風板部Ａと反対側にある排出部Ｂに近づくように取り付けることによって、排出口に近くて水平導風板から離れた形態でイオン発生器を取り付けることによって、帯電イオンの流動が水平導風板に遮られて排出口から吹き出された気流とともに室内空間に拡散できなくなることを防止することができる。それと同時に、開口Ｏまたはイオン流出口Ｍは、排出口３１Ａａの水平導風板３２Ａａ以外の部分に近い（即ち、排出口３１Ａａの吹出気流の吹出経路上に位置する）ため、帯電イオンの拡散性がより良くなる。または、図８に示す位置より装飾パネル３Ａの辺部に近い位置（即ち、図８に示すイオン発生器Ｇの位置の下方）に取り付けてもよく、イオン発生器Ｇにより発生した帯電イオンは、排出口３１Ａａから吹き出された気流に接触し、排出口３１Ａａから吹き出された気流とともに室内空間に拡散することを確保すればよく、これにより、室内空間に存在するウイルス、細菌を死滅させる。 According to the above-mentioned structure, the ion generation assembly 4 is attached so that the outlet O of the ion generation assembly 4 is located at a position close to the discharge portion B on the opposite side of the baffle plate portion A of the discharge port 31Aa, or the ion generator. By attaching G so that the ion outlet M of the generator case G2 is close to the discharge portion B on the opposite side of the baffle plate portion A of the discharge port 31Aa, the G is close to the discharge port and away from the horizontal baffle plate. By attaching an ion generator, it is possible to prevent the flow of charged ions from being blocked by the horizontal baffle plate and being unable to diffuse into the indoor space together with the air flow blown out from the discharge port. At the same time, since the opening O or the ion outlet M is close to the portion of the discharge port 31Aa other than the horizontal baffle plate 32Aa (that is, located on the blowout path of the blowout airflow of the discharge port 31Aa), the diffusivity of charged ions. Will be better. Alternatively, it may be attached to a position closer to the side of the decorative panel 3A than the position shown in FIG. 8 (that is, below the position of the ion generator G shown in FIG. 8), and the charged ions generated by the ion generator G may be attached. It suffices to ensure that it comes into contact with the airflow blown out from the discharge port 31Aa and diffuses into the indoor space together with the airflow blown out from the discharge port 31Aa, thereby killing viruses and bacteria existing in the indoor space.
　また、上述した構造により、室内機１が辺部に位置する排出口のみを有する場合に、イオン発生アセンブリ４またはイオン発生器Ｇを辺部に位置する排出口に近い隅部に取り付けることで、イオン発生器Ｇが冷風や熱風の環境に曝されて劣化することを避けることができる。さらに、上記では、第二排出口から吹き出された気流の流動方向に対する、イオン発生アセンブリ４の開口Ｏまたはイオン発生器Ｇの発生器ケースＧ２のイオン流出口Ｍの角度の設定を記載したが、それに限らない。例えば、イオン発生アセンブリ４またはイオン発生器Ｇが図８に示す片側送気式室内機の辺部に位置する排出口に近い隅部に取り付けられた場合に、辺部に位置する排出口に水平導風板が設けられたため、該排出口から吹き出された大部分の気流は、水平導風板のガイド方向に従って吹き出され、該水平導風板の両側へ吹き出さる気流は、比較的に少ないため、この情况に、開口Ｏが形成された壁部４３または発生器ケースＧ２のイオン流出口Ｍが形成された面は、平面Ｐに対して該排出口から離れる方向に向かって傾斜する傾斜角度α≦１０°であり、好ましくは、該傾斜角度αは０°である（即ち、装飾パネルの位置する平面に垂直である）。さらに、上述した辺部に位置する排出口に垂直導風板がさらに設けられたときに、該傾斜角度α≦６０°であり、好ましくはα≦５０°である。 Further, according to the above-mentioned structure, when the indoor unit 1 has only the discharge port located on the side portion, the ion generation assembly 4 or the ion generator G can be attached to the corner portion near the discharge port located on the side portion. It is possible to prevent the ion generator G from being exposed to the environment of cold air or hot air and deteriorating. Further, in the above, the setting of the angle of the opening O of the ion generation assembly 4 or the ion outlet M of the generator case G2 of the ion generator G with respect to the flow direction of the airflow blown out from the second discharge port has been described. Not limited to that. For example, when the ion generation assembly 4 or the ion generator G is attached to a corner near the discharge port located on the side of the one-sided air supply type indoor unit shown in FIG. 8, it is horizontal to the discharge port located on the side. Since the baffle plate is provided, most of the airflow blown out from the outlet is blown out according to the guide direction of the horizontal baffle plate, and the airflow blown out to both sides of the horizontal baffle plate is relatively small. In this situation, the wall portion 43 on which the opening O is formed or the surface on which the ion outlet M of the generator case G2 is formed is inclined at an inclination angle α with respect to the plane P in a direction away from the discharge port. ≤10 °, preferably the tilt angle α is 0 ° (ie, perpendicular to the plane on which the decorative panel is located). Further, when a vertical baffle plate is further provided at the discharge port located on the side portion described above, the inclination angle is α ≦ 60 °, preferably α ≦ 50 °.
　さらに、室内機本体２の装飾パネルの隅部３０ｅ、３０ｆ、３０ｇ、３０ｈに近い部分に冷媒接続管（例えば、銅管）またはドレインパンに接続された排水管が取り付けられることがあり、この場合に、装飾パネル３の冷媒接続管または排水管が取り付けられた隅部に第二排出口が設けられるが、対応するイオン発生器Ｇを取り付けない。これは、冷媒接続管または排水管が取り付けられた隅部では、温度の変化により冷媒接続管の表面に凝縮水が形成されることが多く、排水管自体が機器内部の熱交換器の表面に形成された凝縮水を受ける機能を果たすため、冷媒接続管または排水管の近傍に凝縮水が存在することが避けられず、該隅部にイオン発生器Ｇを取り付けると、凝縮水がイオン発生器Ｇの内部に流入するおそれがあり、大きな安全上の問題が発生するためである。このような状況の発生を避けるために、好ましくは、装飾パネル３の４つの隅部３０ｅ、３０ｆ、３０ｇ、３０ｈのうち、冷媒接続管または排水管が取り付けられていない少なくとも１つの隅部にイオン発生器Ｇを取り付ける。 Further, a refrigerant connecting pipe (for example, a copper pipe) or a drain pipe connected to a drain pan may be attached to a portion close to the corners 30e, 30f, 30g, and 30h of the decorative panel of the indoor unit main body 2. A second discharge port is provided in the corner of the decorative panel 3 to which the refrigerant connection pipe or the drain pipe is attached, but the corresponding ion generator G is not attached. This is because in the corners where the refrigerant connection pipe or drain pipe is attached, condensed water is often formed on the surface of the refrigerant connection pipe due to changes in temperature, and the drain pipe itself is on the surface of the heat exchanger inside the equipment. In order to fulfill the function of receiving the formed condensed water, it is inevitable that the condensed water exists in the vicinity of the refrigerant connection pipe or the drain pipe, and when the ion generator G is attached to the corner, the condensed water becomes the ion generator. This is because there is a possibility that it may flow into the inside of G, which causes a big safety problem. In order to avoid the occurrence of such a situation, it is preferable that ions are formed in at least one of the four corners 30e, 30f, 30g and 30h of the decorative panel 3 to which the refrigerant connecting pipe or the drain pipe is not attached. Install the generator G.

　イオン発生部Ｇの放電電極の電極ヘッドを排出口の下流側に位置させることで、帯電イオンを自然に拡散する経路を経て排出口から吹き出された空気の流動経路に直接位置させることができ、これにより、帯電イオンの拡散性を高めることができる。 By locating the electrode head of the discharge electrode of the ion generation unit G on the downstream side of the discharge port, it can be directly positioned in the flow path of the air blown out from the discharge port through the path of naturally diffusing charged ions. This makes it possible to increase the diffusivity of charged ions.

By providing an ion insufflator, the charged ions generated by the ion generating unit G1 can be actively blown out, so that the charged ions are actively brought into contact with the air flow blown out from the discharge port, and eventually the charged ions are diffused. Further enhance sex.

By applying a coating that prevents the charged ions from being adsorbed on the above-mentioned portion, it is possible to further prevent the occurrence of a situation in which the utilization rate of the charged ions is lowered due to the adsorption of the charged ions on the metal member.

By selecting a material that can prevent the adsorption of charged ions and manufacturing the ion generation assembly 4 and the generator case G2, the charged ions are adsorbed on the ion generation assembly 4 and the generator case G2 in the process of blowing out or flowing out. It is possible to prevent the occurrence of a situation in which the actual utilization rate of charged ions is lowered due to the above.
