Description
本発明は、空気調和装置の室内機および空気調和装置に関するものである。 The present invention relates to an indoor unit of an air conditioner and an air conditioner.
一般工場・クリーンルーム・倉庫などにおいて空調を行う場合、床置き型空気調和装置が使われる場合が多い。この形態の空気調和装置としては、特許文献１の形態の空気調和装置が一般的である。この形態の空気調和装置においても、年々省エネ化の要望が高まりつつある。しかしながら床置き型空気調和装置では、ダクト接続にて使われる場合が多く、ダクトでの吹き出し空気の圧力損失を考慮し、送風機は、比較的高静圧の状態での使用を考慮したものを採用している。その為、一般のビル用対人空気調和装置室内機（天井埋め込み４方向）に比べ、送風機動力が大きくなり、省エネ化を阻害している。そして、送風機への伝動機構は、モータの回転軸および送風機ファンの回転軸にそれぞれ設けたプーリをベルトで張設して構成している。 When air conditioning is performed in general factories, clean rooms, warehouses, etc., floor-standing air conditioners are often used. As an air conditioner of this form, the air conditioner of the form of patent document 1 is common. Also in this form of air conditioner, demand for energy saving is increasing year by year. However, floor-standing air conditioners are often used in duct connection, and in consideration of the pressure loss of the air blown out from the duct, the blower adopts one that is used in a relatively high static pressure state. doing. Therefore, compared with a general building interpersonal air conditioner indoor unit (4 directions embedded in the ceiling), the power of the blower is increased, which impedes energy saving. The transmission mechanism to the blower is configured by stretching a pulley provided on each of the rotation shaft of the motor and the rotation shaft of the blower fan with a belt.
上記特許文献１の記載の形態の空気調和装置の室内機では、各プーリ間のプーリ比を適宜選択することで吹出空気量を任意に設定できるとしているが、プーリの変更やベルトの着脱に伴い、作業者は重量の大きいモータを取り外し持ち上げる等の負担を強いられる作業やモータを誤って脱落させてしまう虞があった。 In the indoor unit of the air conditioner described in the above-mentioned Patent Document 1, the amount of blown air can be arbitrarily set by appropriately selecting the pulley ratio between the pulleys. There is a risk that the operator may be forced to remove the heavy motor and lift the motor or accidentally drop the motor.
また、筐体上部に送風機を配し、その側面に送風機モータを配しているため、送風機寸法を横方向に広げることが出来ず、やや小さめの送風機を選択せざるを得ない。そのため小さな送風機にて静圧を確保しつつ、風量を確保すると、送風機動力が大きくなる傾向にあり、省エネ化を阻害する。 Moreover, since the blower is arranged on the upper part of the housing and the blower motor is arranged on the side surface, the size of the blower cannot be expanded in the lateral direction, and a slightly smaller blower must be selected. Therefore, if the air volume is secured while securing the static pressure with a small blower, the power of the blower tends to increase, which impedes energy saving.
さらに、送風機と熱交換器が近い為、送風機舌部に近い側の送風機吸込み口と熱交換器上部を結ぶラインでの風速が大きくなり、熱交換器通過風速分布が大きく偏分布となる。このため、熱交換器通風抵抗が大きくなり、送風機が負担する静圧分の仕事が大きくなる。よってこれもまた、送風機動力を大きくさせ、省エネ化を阻害する。 Furthermore, since the blower and the heat exchanger are close to each other, the wind speed at the line connecting the blower inlet on the side close to the blower tongue and the upper part of the heat exchanger is increased, and the heat exchanger passing wind speed distribution is largely uneven. For this reason, a heat exchanger ventilation resistance becomes large and the work for the static pressure which a blower bears becomes large. Therefore, this also increases the power of the blower and hinders energy saving.
本発明では、上記のような問題を鑑み、モータの着脱を容易にしてメンテナンス性を向上させた空気調和装置の室内機を提供することを目的とし、さらには例えば空気調和装置の室内機内のレイアウトを見直すことで、室内機機内の通風抵抗の削減と、送風機効率の向上を図り、室内機送風機動力を削減させ、省エネ化を図ることを目的とする。 An object of the present invention is to provide an indoor unit of an air conditioner in which the motor is easily attached and detached and the maintainability is improved in view of the above problems, and further, for example, a layout in the indoor unit of the air conditioner. The purpose is to reduce the ventilation resistance in the indoor unit and improve the blower efficiency, to reduce the power of the indoor unit blower, and to save energy.
上記課題を解決するために、例えば特許請求の範囲に記載の構成を採用する。本願の空気調和装置は上記課題を解決する手段として、ファンランナがケーシングに覆われる送風機と、該送風機を駆動するモータと、前記送風機側プーリおよび前記モータ側プーリにベルトが巻き掛けられて前記モータの動力を前記送風機に伝える伝動機構と、が筐体内に設けられ、前記筐体内に空気を吸い込む吸込み口と、吸い込まれた空気を前記送風機により前記筐体外へ吹き出す吹出し口と、前記筐体内の空気と内部を流れる冷媒とを熱交換させる熱交換器と、を備える空気調和機の室内機において、前記モータは、スライドレールに固定されることで移動可能に設けられ、前記スライドレールに沿って移動することで前記送風機側プーリの回転軸と前記モータ側プーリの回転軸との距離が変化することを特徴とする。 In order to solve the above problems, for example, the configuration described in the claims is adopted. The air conditioner of the present application is a means for solving the above-mentioned problems, as a fan in which a fan runner is covered by a casing, a motor for driving the fan, a belt wound around the fan-side pulley and the motor-side pulley, and the motor A transmission mechanism that transmits the power of the air to the blower, and a suction port that sucks air into the housing, a blowout port that blows the sucked air out of the housing by the blower, An air conditioner indoor unit comprising: a heat exchanger that exchanges heat between air and a refrigerant that flows therein; and the motor is provided so as to be movable by being fixed to a slide rail, along the slide rail The distance between the rotating shaft of the blower side pulley and the rotating shaft of the motor side pulley is changed by the movement.
本発明によれば、メンテナンス性を向上させた空気調和装置の室内機を提供することができる。さらには、例えば室内機機内通風抵抗を抑えつつ、送風機効率を改善することが出来、室内機送風機動力の削減が可能となる。なお、構成及び効果の詳細は、以下の実施形態の説明により明らかにされる。 ADVANTAGE OF THE INVENTION According to this invention, the indoor unit of the air conditioning apparatus which improved the maintainability can be provided. Furthermore, for example, the blower efficiency can be improved while suppressing the ventilation resistance in the indoor unit, and the power of the indoor unit blower can be reduced. The details of the configuration and the effect will be clarified by the following description of the embodiment.
本発明の実施例について以下、図面を用いて説明する。本発明を明確にする為、最初に従来型の床置き空気調和装置室内機の基本配置を示し、構造を説明する。 Embodiments of the present invention will be described below with reference to the drawings. In order to clarify the present invention, first, the basic arrangement of a conventional floor-standing air conditioner indoor unit will be shown and the structure will be described.
図１は、従来型の床置き型空気調和装置室内機の基本配置である。室内機筐体１は、熱交換器２、送風機３、モータ４を持ち、送風機３は、内部にファンランナを持ち、そのファンランナの外側を覆うケーシングを待っている。送風機３とモータ４の間には、前記モータの動力を前記送風機に伝達する為に、送風機側プーリ５、モータ側プーリ６を持ち、ベルト７にて動力を伝達する。また、熱交換器２の側面には、液側冷媒配管８とガス側冷媒配管９が配されている。また空気吸込み口１０は、正面側に配され、空気吹き出し口１１は、上部に配される。 FIG. 1 is a basic layout of a conventional floor-standing air conditioner indoor unit. The indoor unit housing 1 has a heat exchanger 2, a blower 3, and a motor 4. The blower 3 has a fan runner inside, and is waiting for a casing that covers the outside of the fan runner. Between the blower 3 and the motor 4, there is a blower-side pulley 5 and a motor-side pulley 6 to transmit the power of the motor to the blower, and the power is transmitted by the belt 7. A liquid side refrigerant pipe 8 and a gas side refrigerant pipe 9 are arranged on the side surface of the heat exchanger 2. Moreover, the air suction inlet 10 is distribute | arranged to the front side, and the air blowing outlet 11 is distribute | arranged to upper part.
従来機では、送風機３の右側面に対し、モータ４を配している。また、送風機３とモータ４の間に送風機側プーリ５、モータ側プーリ６、ベルト７が配されている。このため、熱交換器右側を通過した空気流れが送風機に入る際に、前述のモータ、ベルトが通風阻害物となり、通風抵抗が大きくなり、送風機仕事が増える。また同時に、送風機の右側面にモータがあることから、送風機の幅寸法が制約を受け、筐体幅に対しやや狭い送風機を使うこととなる。これにより、送風機幅寸法を広げ、送風機効率を改善する手段が取れず、送風機効率もやや低いものを使わざるを得ない。 In the conventional machine, the motor 4 is arranged on the right side surface of the blower 3. A blower side pulley 5, a motor side pulley 6, and a belt 7 are arranged between the blower 3 and the motor 4. For this reason, when the air flow that has passed through the right side of the heat exchanger enters the blower, the motor and belt described above become ventilation obstructions, ventilation resistance increases, and blower work increases. At the same time, since there is a motor on the right side of the blower, the width of the blower is restricted, and a blower that is slightly narrower than the casing width is used. Thereby, the means for expanding the blower width dimension and improving the blower efficiency cannot be taken, and the blower efficiency must be somewhat low.
また、液側冷媒配管８とガス側冷媒配管９が熱交換器２の左側に配されている為、熱交換器はやや右にオフセットしており、送風機は左にオフセットしていることから、熱交換器左側を通過した流れは、送風機入口に入るまで狭い流路を通らねばならず、また熱交換器右側を通過した流れは、前述の通り、モータ、ベルトが通風阻害物となり、通風抵抗が増え、送風機仕事が増え、送風機動力が増える。 In addition, since the liquid side refrigerant pipe 8 and the gas side refrigerant pipe 9 are arranged on the left side of the heat exchanger 2, the heat exchanger is slightly offset to the right, and the blower is offset to the left. The flow that has passed through the left side of the heat exchanger must pass through a narrow flow path until it enters the blower inlet. Increases, blower work increases, and blower power increases.
加えて、熱交換器２の上端と送風機３の下端が近いことから、熱交換器２を通過する空気流れが送風機３に近い側の方に偏流し、熱交換器２の通風速度分布は、偏分布となる。速度分布が偏分布となることは即ち局所的に速い流れが生じているということであり、その部位においては、通風速度が速い為、圧力損失も大きく、送風機仕事を増大させ、送風機動力を増加させる問題点がある。 In addition, since the upper end of the heat exchanger 2 and the lower end of the blower 3 are close, the air flow passing through the heat exchanger 2 drifts toward the side close to the blower 3, and the ventilation speed distribution of the heat exchanger 2 is Partial distribution. The fact that the velocity distribution is uneven distribution means that a fast flow is generated locally. At that portion, the ventilation speed is fast, so the pressure loss is large, the blower work is increased, and the blower power is increased. There is a problem to make.
またモータ４近傍構造は図２に示すように、ベルト７の着脱や張力調整の為、また様々なプーリ径に対応する為、支点ピン１２を中心に上下に移動する構造が取られている。この為、ベルト着脱時やプーリ径変更の際に重力方向とは逆にモータ４を持ち上げながら作業する場合も生ずることから作業者に負担を強いる構造である。またモータ着脱時は、支点ピン１２と角度固定支え１３を同時に取り外すため、作業者が誤って、モータ４を熱交換器２に脱落させる虞もある。 Further, as shown in FIG. 2, the structure in the vicinity of the motor 4 is configured to move up and down around the fulcrum pin 12 in order to attach and detach the belt 7 and adjust the tension, and to cope with various pulley diameters. For this reason, when the belt is attached / detached or when the pulley diameter is changed, there is a case where work is performed while lifting the motor 4 contrary to the direction of gravity. Further, since the fulcrum pin 12 and the angle fixing support 13 are removed at the same time when the motor is attached / detached, there is a possibility that the operator accidentally drops the motor 4 to the heat exchanger 2.
上記羅列の問題点を改善する為、本発明の実施形態では図３および図４に示す構造を採用する。図３（ａ）は本発明の実施形態に係る床置き型室内機の正面断面図を、図３（ｂ）はその側面断面図を示す。また、図４（ａ）は図３におけるモータ４の取り付け部を拡大した正面断面図を、図４（ｂ）はその側面断面図を示す。 In order to improve the problems of the above list, the structure shown in FIGS. 3 and 4 is adopted in the embodiment of the present invention. FIG. 3A is a front sectional view of a floor-standing indoor unit according to the embodiment of the present invention, and FIG. 3B is a side sectional view thereof. 4A is an enlarged front sectional view of the mounting portion of the motor 4 in FIG. 3, and FIG. 4B is a side sectional view thereof.
図４に示すように、送風機７の下部にスライドレール１９を取り付け、モータ４はそのスライドレール１９に固定し移動可能に設ける。スライドレール１９に取り付けられた状態でモータ４を移動させると、送風機側プーリ５の回転軸とモータ側プーリ６の回転軸との距離が変化し、ベルト７にかかる張力が変化する。これにより、ベルト７の着脱や張力調整を行うことができる。さらにモータ４はスライドレール１９に固定しているため、スライドレール１９による支持を受けながら作業を行うことができ筐体内に落下させる虞もない。 As shown in FIG. 4, a slide rail 19 is attached to the lower part of the blower 7, and the motor 4 is fixed to the slide rail 19 and provided to be movable. When the motor 4 is moved while attached to the slide rail 19, the distance between the rotation shaft of the blower side pulley 5 and the rotation shaft of the motor side pulley 6 changes, and the tension applied to the belt 7 changes. Thereby, the attachment and detachment of the belt 7 and the tension adjustment can be performed. Further, since the motor 4 is fixed to the slide rail 19, the work can be performed while receiving support from the slide rail 19, and there is no possibility of dropping into the housing.
また、モータ４は略水平方向に可動するスライドレール１９に取り付けられ、モータ４を前後方向に動かし、ベルト７の張力を調整する。すなわちスライドレール１９は、略水平方向に可動することから、プーリ交換などでベルトを着脱する際に、モータ４の重力方向に移動させる必要がなく、作業者の負担を軽減できる。 The motor 4 is attached to a slide rail 19 that is movable in a substantially horizontal direction, and the motor 4 is moved in the front-rear direction to adjust the tension of the belt 7. That is, since the slide rail 19 is moved in a substantially horizontal direction, it is not necessary to move the motor 4 in the direction of gravity of the motor 4 when the belt is attached or detached by pulley replacement or the like, and the burden on the operator can be reduced.
このようにスライドレール構造とすることで、モータ４を着脱する際は、モータ４をスライドレール１９に従い、室内機筐体１手前側に引くことにより、モータ４が熱交換器２の上端を通過する際も、スライドレールが重力方向の力を受け持つ為、誤って前記モータを熱交換器２に脱落させる虞が無い。 With the slide rail structure as described above, when the motor 4 is attached or detached, the motor 4 passes through the upper end of the heat exchanger 2 by pulling the motor 4 to the front side of the indoor unit housing 1 according to the slide rail 19. In this case, since the slide rail is responsible for the force in the direction of gravity, there is no possibility that the motor is accidentally dropped onto the heat exchanger 2.
図３（ｂ）に示すように、室内機筐体１正面の吸込口１０上部には取り外し可能な開口パネル２０が設けられている。そして、モータ４は、上下方向において送風機３と熱交換器２の間に配され、ベルト７の張り調整を行う為、開口パネル２０のある面からみて前後方向に移動できる構造とする。これにより、作業口となる開口パネル２０側にモータ４を移動できるため着脱作業等が容易となる。 As shown in FIG. 3 (b), a removable opening panel 20 is provided in the upper part of the suction port 10 on the front surface of the indoor unit housing 1. The motor 4 is arranged between the blower 3 and the heat exchanger 2 in the vertical direction, and is configured to be movable in the front-rear direction as viewed from the surface with the opening panel 20 in order to adjust the tension of the belt 7. Thereby, since the motor 4 can be moved to the opening panel 20 side serving as a work opening, attachment / detachment work and the like are facilitated.
ここで、熱交換器２は熱交換面積を増やすため室内機筐体１内に傾斜させて配置され、上面から見た際に左右上下(前後)方向の端部まで広がった形状としている。そのため、開口パネル２０を取り外した際にモータ４が熱交換器２と水平方向に重なり合い、開口パネル２０の開口部とモータ４との間に熱交換器２が介在するように配置されているとモータ４の着脱作業等が煩雑となる。したがって、モータ４を室内機筐体１の最も前方側に移動した際に、モータ４下端が熱交換器２上端を水平に結ぶ線より上部になるよう配している。このようにモータ４は最前部に移動したときに熱交換器２と水平方向に重ならない配置とすることで、室内機筐体１正面の開口パネル２０より、モータ４を確認することが出来き、またモータ４を着脱する際も、熱交換器２の上部にモータ４が配される為、室内機筐体１側正面からモータ４を交換することが容易となる。 Here, in order to increase the heat exchange area, the heat exchanger 2 is inclined and arranged in the indoor unit housing 1 and has a shape that extends to the ends in the left-right and up-down (front-back) directions when viewed from above. Therefore, when the opening panel 20 is removed, the motor 4 overlaps with the heat exchanger 2 in the horizontal direction, and the heat exchanger 2 is disposed between the opening of the opening panel 20 and the motor 4. The attaching / detaching operation of the motor 4 becomes complicated. Therefore, when the motor 4 is moved to the foremost side of the indoor unit housing 1, the lower end of the motor 4 is disposed above the line connecting the upper end of the heat exchanger 2 horizontally. Thus, the motor 4 can be confirmed from the opening panel 20 in front of the indoor unit housing 1 by arranging the motor 4 so as not to overlap the heat exchanger 2 in the horizontal direction when moved to the front. In addition, when the motor 4 is attached or detached, the motor 4 is arranged on the upper part of the heat exchanger 2, so that it is easy to replace the motor 4 from the front of the indoor unit housing 1 side.
本実施例では、室内機筐体１に対し、上部に送風機３を持つが、モータ４の配置を室内機筐体１正面からみて送風機３下部の左側に配し、モータ４の出力軸も送風機３の左側とする。また、上下方向に伸びて冷媒を流出入させる液側冷媒配管８とガス側冷媒配管９とが熱交換器２に接続されている。この液側冷媒配管８とガス側冷媒配管９は熱交換器２の左側面に配されている。これにより送風機側プーリ５、モータ側プーリ６、ベルト７は、送風機３の左側に配され、液側冷媒配管８およびガス側冷媒配管９と同じ室内機筐体１の内壁側に配される形となる。よって、各プーリ、ベルト７は各冷媒配管の上部に位置する形となり上下方向に同じ場所に位置することで、熱交換器２と送風機３の間で、通風阻害物となる影響を極小化でき、送風機動力を抑制することが出来る。 In the present embodiment, the blower 3 is provided at the upper portion of the indoor unit housing 1, but the motor 4 is arranged on the left side of the lower portion of the blower 3 when viewed from the front of the indoor unit housing 1, and the output shaft of the motor 4 is also a blower. 3 on the left side. In addition, a liquid side refrigerant pipe 8 and a gas side refrigerant pipe 9 that extend in the vertical direction and allow the refrigerant to flow in and out are connected to the heat exchanger 2. The liquid side refrigerant pipe 8 and the gas side refrigerant pipe 9 are arranged on the left side surface of the heat exchanger 2. Thus, the blower-side pulley 5, the motor-side pulley 6, and the belt 7 are arranged on the left side of the blower 3, and are arranged on the same inner wall side of the indoor unit housing 1 as the liquid-side refrigerant pipe 8 and the gas-side refrigerant pipe 9. It becomes. Therefore, each pulley and belt 7 are located at the upper part of each refrigerant pipe and are located at the same place in the vertical direction, so that the influence of air flow obstruction between the heat exchanger 2 and the blower 3 can be minimized. The fan power can be suppressed.
また、送風機３と熱交換器２との間にモータ４が配置されることで上下方向に所定の距離を設けて空気流路を確保している。この配置を行うことで、送風機３下端と熱交換器２上端の距離は、従来型の床置き型空気調和装置室内機より広がるが、このことで、熱交換器２上端付近ばかりに空気流れが集中することを避けることが出来、熱交換器２の通風速度分布の偏分布が緩和される。前記偏分布が緩和されることで、通風速度分布の突出部が緩和されるので、熱交換器通風速度の最大値が低くなり、前記速度が低くなることで、熱交換器通風抵抗が改善され、送風機動力を小さく抑えることが出来る。前記熱交換器通風抵抗の改善には、送風機３と熱交換器２の距離が適度に広いことが望ましいが、室内機筐体１の高さ寸法を一定とした場合、前記送風機と熱交換器の間隔を広くし過ぎると熱交換器２の高さを減ずることとなり、空調機能力を減ずる事となる。 Moreover, the motor 4 is arrange | positioned between the air blower 3 and the heat exchanger 2, and the predetermined distance is provided in the up-down direction, and the air flow path is ensured. By performing this arrangement, the distance between the lower end of the blower 3 and the upper end of the heat exchanger 2 is wider than that of the conventional floor-standing air conditioner indoor unit. Concentration can be avoided, and the uneven distribution of the ventilation speed distribution of the heat exchanger 2 is relaxed. As the uneven distribution is relaxed, the protrusion of the ventilation speed distribution is relaxed, so that the maximum value of the heat exchanger ventilation speed is lowered, and the speed is lowered, thereby improving the heat exchanger ventilation resistance. The fan power can be kept small. In order to improve the ventilation resistance of the heat exchanger, it is desirable that the distance between the blower 3 and the heat exchanger 2 is appropriately large. However, when the height of the indoor unit housing 1 is constant, the blower and the heat exchanger If the interval is made too wide, the height of the heat exchanger 2 will be reduced, and the air-conditioning function will be reduced.
図５に、熱交換器２上端と送風機３下端との距離と、通風抵抗との関係を示すが、上記のとおり室内機筐体１の高さ方向の制約または熱交換器２の高さ寸法を考慮し、熱交換器２と送風機３との距離は、送風機３のファンランナ径をｄとして、０．８〜１．０ｄとすることが好ましく、より望ましくは０．９ｄとするのが良い。 FIG. 5 shows the relationship between the distance between the upper end of the heat exchanger 2 and the lower end of the blower 3 and the ventilation resistance. As described above, the restriction in the height direction of the indoor unit housing 1 or the height dimension of the heat exchanger 2 is shown. In consideration of the above, the distance between the heat exchanger 2 and the blower 3 is preferably 0.8 to 1.0 d, more preferably 0.9 d, where d is the fan runner diameter of the blower 3. .
ここでモータ４は、送風機３と熱交換器２との間の空間に配置されるとともに、送風機３とは水平方向に重ならない位置に設けるため、送風機３を室内機筐体１内における左右前後方向の端部まで大型化することが可能である。 Here, the motor 4 is disposed in the space between the blower 3 and the heat exchanger 2 and is provided at a position that does not overlap the blower 3 in the horizontal direction. It is possible to increase the size to the end in the direction.
また、図４に示すように、スライドレール１９は、送風機３のケーシングに直接取り付け、ケーシングをモータ４の重量を支える強度部材として利用する。これにより送風機３のケーシングは、送風機３の送風性能確保の部材としてだけではなく、モータ４の重量を支える構造部材としても機能することから、モータ４の重量を支える構造部材を別途設置する必要が無く、送風機３、モータ４回りの構造を簡略化できると共に、部品点数を抑えることができる。なお、スライドレール１９を送風機３のケーシングに固定せずに設ける場合は、図６に示すようなフレーム構造（骨組み構造）とすることもできる。 As shown in FIG. 4, the slide rail 19 is directly attached to the casing of the blower 3, and the casing is used as a strength member that supports the weight of the motor 4. As a result, the casing of the blower 3 functions not only as a member for ensuring the blowing performance of the blower 3 but also as a structural member that supports the weight of the motor 4. Therefore, it is necessary to separately install a structural member that supports the weight of the motor 4. In addition, the structure around the blower 3 and the motor 4 can be simplified, and the number of parts can be reduced. In addition, when providing the slide rail 19 without fixing to the casing of the air blower 3, it can also be set as a frame structure (frame structure) as shown in FIG.
本実施例は、工場・倉庫向け床置き型の空気調和装置の室内機への適用を考慮したものであるが、これに限らず対人用床置き空気調和装置室内機などへの適用も可能である。本実施例においては、正面吸込み・上部ダクト吹き出しの床置き型空気調和装置室内機への適用例を示したが、本発明は、これに限らず、背面吸込み・上部ダクト吹き出しの床置き型空気調和装置室内機への適用も可能である。この場合の適用例を図７に示す。図３の筐体正面の空気吸込み口１０が封じられ、図７の筐体背面に空気吸込み口１０が設置されている以外は、同一形態である。 Although this embodiment considers the application of floor-standing air conditioners for factories and warehouses to indoor units, it is not limited to this and can also be applied to indoor floor-standing air conditioners for personal use. is there. In the present embodiment, the application example of the front suction / upper duct blowing to the floor-standing air conditioner indoor unit has been shown, but the present invention is not limited to this, and the floor suction air of the rear suction / upper duct blowing is used. Application to the indoor unit of a harmony device is also possible. An application example in this case is shown in FIG. It is the same form except that the air suction port 10 on the front surface of the housing in FIG. 3 is sealed and the air suction port 10 is installed on the back surface of the housing in FIG.
さらに本発明は、室内機筐体１の上部にチャンバーを設け、チャンバーより直接空気を吹き出す形態としても適用可能である。図８に、チャンバーを設け、正面吸込み、正面吹き出しとした場合を示す。上部のダクト接続部が、チャンバー１４になった他は同様である。 Furthermore, the present invention can be applied to a form in which a chamber is provided in the upper part of the indoor unit housing 1 and air is directly blown out from the chamber. FIG. 8 shows a case where a chamber is provided, front suction is performed, and front blowing is performed. It is the same except that the upper duct connection portion is a chamber 14.
このように、本発明は、特に床置き型の室内機に有効であるが、様々な室内機の形態に適用可能である。 As described above, the present invention is particularly effective for floor-standing indoor units, but is applicable to various forms of indoor units.
