JP 2008-249287 A

従来技術による空気調和機の室内機のファンケーシングでは、送風機の吹き出し部の拡大風路を構成するディフューザ部が短いため熱交換器に向けた送風があまり拡散せず、熱交換器周りの風速分布が均一になりにくいため、十分な熱交換器能力が確保できない。また、熱交換室の角の方、特に仕切板近傍においては渦を巻くような空気の流れが発生して円滑な流れ場がつくれず、風量性能が向上しななかったり、乱流騒音の発生を招いたりすることがある。本発明は上記従来の問題点を解決する空気調和機の室内機を提供することを目的とする。   In the fan casing of an indoor unit of an air conditioner according to the prior art, the air flow toward the heat exchanger does not diffuse so much because the diffuser part constituting the expanded air path of the blowing part of the blower is short, and the wind speed distribution around the heat exchanger Since it is difficult to make uniform, sufficient heat exchanger capacity cannot be secured. In addition, a vortexed air flow is generated near the corner of the heat exchange chamber, especially in the vicinity of the partition plate, so that a smooth flow field cannot be created, air flow performance cannot be improved, and turbulent noise is generated. May be invited. An object of the present invention is to provide an indoor unit of an air conditioner that solves the above-described conventional problems.

前記課題を解決するために、空気調和機の室内機本体の内部を仕切板にて、熱交換器が収納された熱交換室と、ファンケーシングと多翼ファンとファンモーターとからなる送風機が収納された送風室とに区画し、熱交換室側に吹出口を設け、送風室側に吸込口を設け、前記送風機の吹き出し部から前記熱交換器近傍まで、高さ方向に拡大させたディフューザ部を備える。   In order to solve the above-mentioned problems, a heat exchange chamber in which a heat exchanger is housed, and a blower comprising a fan casing, a multiblade fan, and a fan motor are housed in a partition plate inside the indoor unit body of the air conditioner. A diffuser section that is divided into a blower chamber, a blower outlet is provided on the heat exchange chamber side, a suction port is provided on the blower chamber side, and is expanded in the height direction from the blowout portion of the blower to the vicinity of the heat exchanger Is provided.

多翼ファンから吹き出された空気は、ディフューザ部を通過する時に縦方向にスムーズに拡大しながら風速が減速し、熱交換器に広範囲に吹きつけられる。   The air blown out from the multiblade fan is smoothly blown up in the vertical direction when passing through the diffuser section, the wind speed is reduced, and the air is blown over a wide range of the heat exchanger.

多翼ファンから吹き出された空気がディフューザ部を通過する時、流れ方向に風路断面積が徐々に拡大されるため風速が徐々に減少して動圧を円滑に回収され、ファン効率が向上して風量性能が向上する。また、渦巻いて逆流する流れが抑制されて流れが円滑になり、乱れが減少して乱流騒音が低減される。   When the air blown from the multiblade fan passes through the diffuser section, the air passage cross-sectional area is gradually expanded in the flow direction, so the wind speed is gradually reduced and the dynamic pressure is recovered smoothly, improving the fan efficiency. Airflow performance is improved. Moreover, the flow which swirls and flows backward is suppressed, the flow becomes smooth, turbulence is reduced, and turbulent noise is reduced.

さらに、多翼ファンから吹き出された空気が熱交換器に吹きつけられる風速は均一な状態に近くなり、熱交換器能力が向上する。   Furthermore, the wind speed at which the air blown from the multiblade fan is blown to the heat exchanger becomes nearly uniform, and the heat exchanger performance is improved.

第１の発明は、空気調和機の室内機本体の内部を仕切板にて、熱交換器が収納された熱交換室と、ファンケーシングと多翼ファンとファンモーターとからなる送風機が収納された送風室とに区画し、熱交換室側に吹出口を設け、送風室側に吸込口を設け、前記送風機の吹き出し部から前記熱交換器近傍まで、高さ方向に拡大させたディフューザ部を備えた
ことを特徴とする。これにより、熱交換器に対して高さ方向の風速分布の均一化を図ることができる。特に、熱交換室の角の方、特に仕切板近傍における渦を巻くような空気の流れの発生を防止することができる。 In the first invention, the interior of the indoor unit body of the air conditioner is partitioned by a heat exchanger chamber in which a heat exchanger is stored, and a blower including a fan casing, a multiblade fan, and a fan motor is stored. It is divided into a blower chamber, a blower outlet is provided on the heat exchange chamber side, a suction port is provided on the blower chamber side, and a diffuser portion that is enlarged in the height direction from the blowout portion of the blower to the vicinity of the heat exchanger is provided. It is characterized by that. Thereby, the uniform wind speed distribution in the height direction can be achieved with respect to the heat exchanger. In particular, it is possible to prevent the generation of an air flow that creates a vortex in the corner of the heat exchange chamber, particularly in the vicinity of the partition plate.

第２の発明は、空気調和機の室内機本体の内部を仕切板にて、熱交換器が収納された熱交換室と、ファンケーシングと多翼ファンとファンモーターとからなる送風機が収納された送風室とに区画し、熱交換室側に吹出口を設け、送風室側に吸込口を設け、前記送風機の吹き出し部から前記熱交換器近傍まで、幅方向に拡大させたディフューザ部を備えたことを特徴とする。これにより、熱交換器に対して幅方向の風速分布の均一化を図ることができる。   In the second invention, the interior of the indoor unit body of the air conditioner is partitioned by a heat exchanger chamber in which a heat exchanger is stored, and a blower including a fan casing, a multiblade fan, and a fan motor is stored. It was divided into a blower chamber, a blower outlet was provided on the heat exchange chamber side, a suction port was provided on the blower chamber side, and a diffuser part expanded in the width direction from the blowout part of the blower to the vicinity of the heat exchanger was provided. It is characterized by that. Thereby, the uniform wind speed distribution in the width direction can be achieved with respect to the heat exchanger.

第３の発明は、空気調和機の室内機本体の内部を仕切板にて、熱交換器が収納された熱交換室と、ファンケーシングと多翼ファンとファンモーターとからなる送風機が収納された送風室とに区画し、熱交換室側に吹出口を設け、送風室側に吸込口を設け、前記送風機の吹き出し部から前記熱交換器近傍まで、高さ方向と幅方向とに拡大させたディフューザ部を備えたことを特徴とする。これにより、熱交換器に対して高さ方向と横方向の風速分布の均一化を図ることができる。特に、熱交換室の角の方、特に仕切板近傍における渦を巻くような空気の流れの発生を防止することができる。   In the third aspect of the invention, the interior of the indoor unit body of the air conditioner is partitioned by a heat exchange chamber in which a heat exchanger is accommodated, and a blower including a fan casing, a multiblade fan, and a fan motor is accommodated. It was divided into a blower chamber, a blower outlet was provided on the heat exchange chamber side, a suction port was provided on the blower chamber side, and expanded in the height direction and the width direction from the blowout part of the blower to the vicinity of the heat exchanger.

In particular, it is possible to prevent the generation of an air flow that creates a vortex in the corner of the heat exchange chamber, particularly in the vicinity of the partition plate.

第４の発明は、ディフューザ内部に、空気の流れを幅方向に拡散させるように制御するためのガイダを配置する。これにより、熱交換器に対して幅方向の風速分布の均一化がより以上に図ることができる。   In the fourth aspect of the invention, a guider for controlling the flow of air in the width direction is arranged inside the diffuser.

以下に本発明の実施の形態を図１から図５までに沿って説明する。   Embodiments of the present invention will be described below with reference to FIGS.

（実施の形態１）
図１は、本発明の実施の形態１における空気調和機の室内機の縦断面図、図２は同平面断面図である。図１、図２において、空気調和機の室内機本体１の２つの側面に対向するように吸込口２と吹出口３とが設けられ、その内部に、多翼ファン４と多翼ファン４を囲むように配置されたスクロール形状を有するファンケーシング５とファンモーター６とで構成される送風機７と、熱交換器８とが配置され、送風機７と熱交換器８との間には送風室９と熱交換室１０とに区画する仕切板１１が配設されている。２台の多翼ファン４の中央部にはファンモーター６が配置され、ファンモーター６の両軸シャフト６ａの両端にそれぞれ多翼ファン４が固定されている。熱交換室１０の下部には、ドレンパン１２が配設されている。 (Embodiment 1)
1 is a longitudinal sectional view of an indoor unit of an air conditioner according to Embodiment 1 of the present invention, and FIG. 2 is a sectional plan view of the same. 1 and 2, an air inlet 2 and an air outlet 3 are provided so as to face two side surfaces of an indoor unit main body 1 of an air conditioner, and a multi-blade fan 4 and a multi-blade fan 4 are provided therein. A blower 7 composed of a fan casing 5 having a scroll shape and a fan motor 6 arranged so as to surround the fan 7 and a heat exchanger 8 are arranged, and a blower chamber 9 is provided between the blower 7 and the heat exchanger 8. And a heat exchanger chamber 10 are provided. A fan motor 6 is disposed at the center of the two multi-blade fans 4, and the multi-blade fans 4 are fixed to both ends of both shaft shafts 6 a of the fan motor 6. A drain pan 12 is disposed in the lower part of the heat exchange chamber 10.

送風機７の吹き出し部７ａには、熱交換器８までディフューザ部１３が吹き出し部７ａを延長するように形成されている。ディフューザ部１３の上面１３ａは熱交換器８の上端８ａの近接位置まで形成され、ディフューザ部１３の下面１３ｂは熱交換器８の下端８ｂの近接位置まで形成され、空気の流れ方向に沿って高さ方向寸法が徐々に拡大している。   A diffuser portion 13 is formed in the blowing portion 7 a of the blower 7 so as to extend the blowing portion 7 a up to the heat exchanger 8. The upper surface 13a of the diffuser portion 13 is formed up to a position close to the upper end 8a of the heat exchanger 8, and the lower surface 13b of the diffuser portion 13 is formed up to a position close to the lower end 8b of the heat exchanger 8 and is high along the air flow direction. The vertical dimension gradually increases.

また、ディフューザ部１３の側面１３ｃは、幅方向寸法が拡大しながら、室内機本体１に近接するまで、又は隣接するケーシング５のディフューザ部１３の側面１３ｃと当接する側面当接位置１３ｄまで形成されている。図１においては、ディフューザ部１３のいずれの面も直線的な平面として形成しているが、拡大方向の曲線的な平面とすれば、気流はよりスムーズに拡大されて好適である。   Further, the side surface 13c of the diffuser portion 13 is formed up to the side surface contact position 13d that contacts the side surface 13c of the diffuser portion 13 of the adjacent casing 5 while increasing the widthwise dimension until it approaches the indoor unit body 1. ing. In FIG. 1, any surface of the diffuser portion 13 is formed as a linear plane. However, if it is a curved plane in the expansion direction, the airflow is preferably expanded more smoothly.

上記構成により、ファンモーター６が駆動されて、両軸シャフト６ａに直結されている各々の多翼ファン４が回転する。それによって、室内機本体１の吸込口２より吸い込まれた空気が吹き出し部７ａより吹き出し、ディフューザ部１３を通って、熱交換器８を通過する。さらに、熱交換器８で熱交換された空気は、室内機本体１の吹出口３より放出される。   With the above configuration, the fan motor 6 is driven and each multiblade fan 4 directly connected to the both shafts 6a rotates. Thereby, the air sucked from the suction port 2 of the indoor unit main body 1 is blown out from the blowing portion 7a, passes through the diffuser portion 13 and passes through the heat exchanger 8. Furthermore, the air heat-exchanged by the heat exchanger 8 is discharged from the air outlet 3 of the indoor unit body 1.

ディフューザ部１３は、流れ方向に沿って高さ方向及び幅方向に徐々に拡大するため、風速が徐々に減少して動圧が円滑に回収され、ファン効率が向上して風量性能が向上する。さらに、高さ方向及び幅方向に風速が均一化して熱交換器能力が向上する。また、熱交換室１０の角の方、特に仕切板１１近傍における渦を巻くような空気の流れの発生を防止することができ、流れが円滑になり乱れが減少して乱流騒音が低減する。   Since the diffuser portion 13 gradually expands in the height direction and the width direction along the flow direction, the wind speed gradually decreases, the dynamic pressure is smoothly recovered, the fan efficiency is improved, and the air flow performance is improved. Furthermore, the wind speed is made uniform in the height direction and the width direction, and the heat exchanger capacity is improved. Further, it is possible to prevent the generation of an air flow that vortexes around the corner of the heat exchange chamber 10, particularly in the vicinity of the partition plate 11, and the flow becomes smooth and the turbulence is reduced to reduce the turbulent noise. .

なお、本実施の形態１においては、ディフューザ部１３を高さ方向寸法及び幅方向寸法を同時に拡大するように形成して効果を最大限引き出すようにしたが、ディフューザ部１３を高さ方向に拡大する上面１３ａと下面１３ｂだけ、又は幅方向に拡大する側面１３ｃだけのいずれかを形成して、いずれかの効果を発揮するだけとすることも可能である。   In the first embodiment, the diffuser portion 13 is formed so as to enlarge the height direction dimension and the width direction size simultaneously to maximize the effect. However, the diffuser portion 13 is enlarged in the height direction. It is also possible to form only one of the upper surface 13a and the lower surface 13b, or only the side surface 13c that expands in the width direction, so that any of the effects can be exhibited.

また、後述する図３に示すように、ディフューザ部１３を熱交換器８の上端８ａ及び下端８ｂに近接するほどまで形成しなくとも、最も風速が大きい吹き出し部５ａから所定長さだけ延長して拡大するようにしても良い。その所定長さとしては、ディフューザ部１３の上面１３ａは室内機本体１の天面にスムーズに気流を沿わせられる程度の長さがあれば良く、吹き出し部７ａが天面に近接しているほど短くて済む。また、ディフューザ部１３の下面１３ｂは、吹き出した気流が仕切板１１側に逆流して渦巻くような乱流を抑制できれば良く、熱交換器８の下端８ｂに向けて延長した下面１３ｂが、少なくとも熱交換器８の下端８ｂと仕切板１１との中央位置まで到達する長さがあれば良い。   Further, as shown in FIG. 3 to be described later, even if the diffuser portion 13 is not formed so close to the upper end 8a and the lower end 8b of the heat exchanger 8, it is extended by a predetermined length from the blowing portion 5a having the highest wind speed. You may make it expand. As the predetermined length, the upper surface 13a of the diffuser unit 13 only needs to have a length that allows the airflow to smoothly follow the top surface of the indoor unit body 1, and the closer the blowing unit 7a is to the top surface. It's short. Moreover, the lower surface 13b of the diffuser part 13 should just be able to suppress the turbulent flow in which the blown airflow flows backward to the partition plate 11 side and swirls, and the lower surface 13b extended toward the lower end 8b of the heat exchanger 8 has at least heat. It is sufficient that the length reaches the center position between the lower end 8 b of the exchanger 8 and the partition plate 11.

このようにディフューザ部１３を短く形成した場合には、ディフューザ部１３が多翼ファン４に対して個別に配設されて小型で済み、図１の構成と比較してコストを低減することが可能であるとともに、組み立ても容易である。   Thus, when the diffuser part 13 is formed short, the diffuser part 13 is individually disposed with respect to the multi-blade fan 4 and can be downsized, and the cost can be reduced as compared with the configuration of FIG. And easy to assemble.

また、送風機７の多翼ファン４とファンケーシング５との組み合わせは２個に限定するものではなく、１個以上あれば良い。   Moreover, the combination of the multiblade fan 4 and the fan casing 5 of the blower 7 is not limited to two, and may be one or more.

（実施の形態２）
図３は、本発明の実施の形態２における空気調和機の室内機の縦断面図、図４は同平面断面図である。図３、図４において、実施の形態１と同じ構成については説明を省略する。 (Embodiment 2)
FIG. 3 is a longitudinal sectional view of an indoor unit of an air conditioner according to Embodiment 2 of the present invention, and FIG. 4 is a sectional plan view of the same. 3 and 4, the description of the same configuration as that of Embodiment 1 is omitted.

送風機７の吹き出し部７ａには、ディフューザ部１３が吹き出し部７ａを熱交換器８の上端８ａ及び下端８ｂに近接するまでは達しない程度の近傍まで延長するように形成され、流れ方向に沿って高さ方向及び幅方向に徐々に拡大する。そのディフューザ部１３の内部には、幅方向に流れを拡散させるように制御するためのガイダ１４ａが配置されている。これによって、さらに動圧が円滑に回収されてファン効率が向上し、風量性能が向上する。また、特に幅方向の空気の流れが整流されて風速の均一化をより以上に図ることができ、熱交換器能力が向上する。また、流れがより円滑になり、乱れが減少して乱流騒音がさらに低減される。   In the blowing part 7a of the blower 7, the diffuser part 13 is formed so as to extend to the vicinity of the extent that the blowing part 7a does not reach the proximity of the upper end 8a and the lower end 8b of the heat exchanger 8, and along the flow direction It gradually expands in the height and width directions. A guider 14a for controlling the flow to diffuse in the width direction is disposed inside the diffuser portion 13. As a result, the dynamic pressure is recovered more smoothly, the fan efficiency is improved, and the air flow performance is improved. In particular, the flow of air in the width direction is rectified to make the wind speed more uniform, and the heat exchanger capacity is improved. Also, the flow becomes smoother, turbulence is reduced, and turbulent noise is further reduced.

（実施の形態３）
図５は、本発明の実施の形態３における空気調和機の室内機の縦断面図、図６は同平面
断面図である。図５，図６において、実施の形態１と同じ構成については説明を省略する。 (Embodiment 3)
FIG. 5 is a longitudinal sectional view of an indoor unit of an air conditioner according to Embodiment 3 of the present invention, and FIG. 6 is a sectional plan view of the same. 5 and 6, the description of the same configuration as that of the first embodiment is omitted.

送風機７の吹き出し部７ａには、ディフューザ部１３が吹き出し部７ａを熱交換器８の上端８ａ及び下端８ｂに近接するまでは達しない程度の近傍まで延長するように形成され、流れ方向に沿って高さ方向及び幅方向に徐々に拡大する。そのディフューザ部１３の内部には、高さ方向に流れを拡散させるように制御するためのガイダ１４ｂが配置されている。これによって、さらに動圧が円滑に回収されてファン効率が向上し、風量性能が向上する。また、特に高さ方向の空気の流れが整流されて風速の均一化をより以上に図ることができ、熱交換器能力が向上する。また、流れがより円滑になり、乱れが減少して乱流騒音がさらに低減される。   In the blowing part 7a of the blower 7, the diffuser part 13 is formed so as to extend to the vicinity of the extent that the blowing part 7a does not reach the proximity of the upper end 8a and the lower end 8b of the heat exchanger 8, and along the flow direction It gradually expands in the height and width directions. A guider 14b for controlling the flow to diffuse in the height direction is disposed inside the diffuser portion 13. As a result, the dynamic pressure is recovered more smoothly, fan efficiency is improved, and air flow performance is improved. In addition, the flow of air in the height direction is particularly rectified, so that the wind speed can be made more uniform, and the heat exchanger capability is improved. Also, the flow becomes smoother, turbulence is reduced, and turbulent noise is further reduced.

なお、実施の形態１，２，３に記載した構成は、それぞれ自由に組み合わせることが可能である。例えば、実施の形態１のディフューザ部１３の構成にガイダ１４ａ，１４ｂを組み合わせる時には、ガイダ１４ａ，１４ｂをもっと熱交換器８に近づけるように構成して、熱交換器８への風速を均一にすることができる。   The configurations described in Embodiments 1, 2, and 3 can be freely combined with each other. For example, when the guiders 14a and 14b are combined with the configuration of the diffuser unit 13 of the first embodiment, the guiders 14a and 14b are configured to be closer to the heat exchanger 8 so that the wind speed to the heat exchanger 8 is uniform. be able to.

以上のように、本発明のように送風機のファンケーシングを延長したディフューザ部を構成することにより、ディフューザ部を空気が通過する時、動圧が円滑に回収されてファン効率が向上し、風量性能が向上したり、熱交換器に吹きつけられる風速が均一な状態に近くなり、熱交換器能力が向上したり、流れが円滑になり、乱れが減少して乱流騒音が低減されたりするもので、ダクトエアコンなどのほか、多翼ファンとファンケーシングを用いて熱交換器に送風する空調機に適用できる。   As described above, by configuring the diffuser part in which the fan casing of the blower is extended as in the present invention, when air passes through the diffuser part, the dynamic pressure is smoothly recovered, the fan efficiency is improved, and the air flow performance Or the air velocity blown to the heat exchanger is almost uniform, improving the heat exchanger capacity, smoothing the flow, reducing turbulence and reducing turbulent noise In addition to duct air conditioners, etc., the present invention can be applied to air conditioners that blow air to a heat exchanger using a multiblade fan and a fan casing.
