Description

空気調和機の室内機Indoor unit of air conditioner
　本発明は、第１の送風機、第２の送風機及び熱交換器が筐体の内部に設けられた空気調和機の室内機に関する。 The present invention relates to an indoor unit of an air conditioner in which a first blower, a second blower and a heat exchanger are provided inside a housing.
　従来、送風機と熱交換器とが筐体の内部に設けられた空気調和機の室内機が知られている。送風能力を高めることを目的に、送風機として遠心ファンが採用された例として、特許文献１には、本体の両端部にそれぞれ遠心ファンが設けられ、本体の中央部に熱交換器が設けられた空気調和機の室内機が開示されている。特許文献１は、本体の内部が、連通口が形成された仕切りによって幅方向において３つに区画されている。このうち、中央部には、空気を吸い込む吸込口が形成されており、吸込口から吸い込まれた空気と冷媒との間で熱交換する熱交換器が設けられている。 Conventionally, an indoor unit of an air conditioner in which a blower and a heat exchanger are provided inside a housing is known. As an example in which a centrifugal fan is adopted as a blower for the purpose of enhancing the blowing capacity, Patent Document 1 provides centrifugal fans at both ends of the main body and a heat exchanger at the center of the main body. The indoor unit of the air conditioner is disclosed. In Patent Document 1, the inside of the main body is divided into three in the width direction by a partition in which a communication port is formed. Of these, a suction port for sucking air is formed in the central portion, and a heat exchanger for heat exchange between the air sucked from the suction port and the refrigerant is provided.
　そして、中央部には、吸込口と連通口とを接続する空気流路が形成されている。また、両端部には、空気を吹き出す吹出口が形成されており、吸込口から吸い込まれて熱交換された後に連通口を通過した空気を吹出口に導く遠心ファンが設けられている。特許文献１において、中央部の吸込口から吸い込まれた空気は、熱交換器で冷媒との間で熱交換された後に連通口を通過し、遠心ファンの吸い込み側に至り、遠心ファンの側面の吹き出し側から両端部の吹出口をとおって室内に吹き出される。 And, in the central part, an air flow path connecting the suction port and the communication port is formed. Further, air outlets for blowing air are formed at both ends, and centrifugal fans are provided to guide the air that has passed through the communication port to the air outlet after being sucked from the suction port and exchanging heat. In Patent Document 1, the air sucked from the suction port in the central portion passes through the communication port after heat exchange with the refrigerant by the heat exchanger, reaches the suction side of the centrifugal fan, and reaches the suction side of the centrifugal fan. It is blown into the room from the blowout side through the outlets at both ends.
特開２００４－９２９５０号公報Japanese Unexamined Patent Publication No. 2004-92950
　空気調和機の室内機は、通例、使用者が使用する空調対象空間の天井付近に設置される場合が多い。特許文献１に開示された空気調和機の室内機は、中央部から空気が吸い込まれ、熱交換された空気が両端部から吹き出される。即ち、室内機の中央部付近には、熱交換された空気が吹き出されない。このように、室内機の両端部という狭い空間からのみ、熱交換された空気が吹き出されるため、吹き出される空気の勢いが強く速度が速い。このため、勢いが強い空気が、空調対象空間にいる使用者に当たって、使用者の快適性を損なうおそれがある。 The indoor unit of the air conditioner is usually installed near the ceiling of the air-conditioned space used by the user. In the indoor unit of the air conditioner disclosed in Patent Document 1, air is sucked from the central portion, and the heat-exchanged air is blown out from both ends. That is, the heat-exchanged air is not blown out near the central portion of the indoor unit. In this way, since the heat-exchanged air is blown out only from the narrow space of both ends of the indoor unit, the momentum of the blown out air is strong and the speed is high. For this reason, strong air may hit the user in the air-conditioned space and impair the comfort of the user.
　本発明は、上記のような課題を解決するためになされたもので、使用者の快適性を損なわない空気調和機の室内機を提供するものである。 The present invention has been made to solve the above problems, and provides an indoor unit of an air conditioner that does not impair the comfort of the user.
　本発明に係る空気調和機の室内機は、幅方向に延在し、幅方向の一端部であり、空気を吸い込む第１の吸込口が形成された第１の側面、幅方向の他端部であり、空気を吸い込む第２の吸込口が形成された第２の側面及び第１の側面と第２の側面とを接続する接続面を有する筐体と、筐体において幅方向に延在し、冷媒と空気との間で熱交換する熱交換器と、筐体の幅方向の一端部に設けられ、第１の吸込口から吸いこまれた空気を熱交換器に送る第１の送風機と、筐体の幅方向の他端部に設けられ、第２の吸込口から吸いこまれた空気を熱交換器に送る第２の送風機と、を備え、筐体の接続面には、第１の送風機及び第２の送風機によって熱交換器に送られて冷媒との間で熱交換された空気を吹き出す吹出口が形成されている。 The indoor unit of the air exchanger according to the present invention extends in the width direction and is one end in the width direction, a first side surface on which a first suction port for sucking air is formed, and the other end in the width direction. A housing having a second side surface on which a second suction port for sucking air is formed and a connecting surface connecting the first side surface and the second side surface, and a housing extending in the width direction in the housing. A heat exchanger that exchanges heat between the refrigerant and air, and a first blower that is provided at one end in the width direction of the housing and sends air sucked from the first suction port to the heat exchanger. A second blower provided at the other end in the width direction of the housing and sending the air sucked from the second suction port to the heat exchanger is provided, and the first blower is provided on the connecting surface of the housing. And an air outlet is formed to blow out the air sent to the heat exchanger by the second blower and exchanged heat with the refrigerant.
　本発明によれば、吹出口が、第１の側面と第２の側面とを接続する接続面に形成されている。このため、吹出口が第１の側面又は第２の側面に形成される場合に比べて、吹出口を大きくすることができる。この場合、吹出口から吹き出される空気の勢いが弱く速度が低い。従って、空調対象空間にいる使用者に空気が当たっても、使用者の快適性を損なうことを抑制することができる。 According to the present invention, the air outlet is formed on the connecting surface connecting the first side surface and the second side surface. Therefore, the air outlet can be made larger than the case where the air outlet is formed on the first side surface or the second side surface. In this case, the momentum of the air blown out from the outlet is weak and the speed is low. Therefore, even if the user in the air-conditioned space is exposed to air, it is possible to prevent the user from being impaired in comfort.

The compressor 6 sucks in the refrigerant in a low temperature and low pressure state, compresses the sucked refrigerant into a refrigerant in a high temperature and high pressure state, and discharges the refrigerant. The flow path switching device 7 switches the direction in which the refrigerant flows in the refrigerant circuit 4, and is, for example, a four-way valve.

The first rotating shaft 14a of the first blower 12a and the second rotating shaft 14b of the second blower 12b are arranged on the same shaft.
　（空気の流れ）
　次に、室内機３における空気の流れについて説明する。第１の送風機１２ａ及び第２の送風機１２ｂが第１のモータ１３ａ及び第２のモータ１３ｂによって回転駆動すると、空調対象空間の空気は、第１の吸込口３１ａ及び第２の吸込口３１ｂから吸い込まれる。吸い込まれた空気は、第１の送風機１２ａ及び第２の送風機１２ｂによって第１の送風室２８ａ及び第２の送風室２８ｂの内部に吹き出され、第１の通風路３４及び第２の通風路３５をとおって熱交換室２９に流入する。熱交換室２９に流入した空気は、熱交換室２９に設けられたそれぞれの熱交換器１１に流れ、熱交換器１１において、複数の伝熱管の内部に流れる冷媒との間で熱交換される。熱交換された空気は、空調空気として、熱交換器１１から流出して上部吹出口３２ａ及び下部吹出口３２ｂから吹き出す。 (the flow of air)
Next, the air flow in the indoor unit 3 will be described. When the first blower 12a and the second blower 12b are rotationally driven by the first motor 13a and the second motor 13b, the air in the air-conditioned space is sucked from the first suction port 31a and the second suction port 31b. Is done. The sucked air is blown into the inside of the first blower chamber 28a and the second blower chamber 28b by the first blower 12a and the second blower 12b, and the first ventilation passage 34 and the second ventilation passage 35 It flows into the heat exchange chamber 29 through. The air that has flowed into the heat exchange chamber 29 flows into each of the heat exchangers 11 provided in the heat exchange chamber 29, and in the heat exchanger 11, heat is exchanged with the refrigerant flowing inside the plurality of heat transfer tubes. .. The heat-exchanged air flows out from the heat exchanger 11 as conditioned air and is blown out from the upper outlet 32a and the lower outlet 32b.
　本実施の形態１によれば、吹出口３２が、第１の側面２１と第２の側面２２とを接続する接続面２３に形成されている。このため、吹出口３２が第１の側面２１又は第２の側面２２に形成される場合に比べて、吹出口３２を大きくすることができる。本実施の形態１では、吹出口３２は、筐体２０の幅方向に延在している。この場合、吹出口３２から吹き出される空気は、幅広となるため、勢いが弱く速度が低い。従って、空調対象空間にいる使用者に空気が当たっても、使用者の快適性を損なうことを抑制することができる。 According to the first embodiment, the air outlet 32 is formed on the connecting surface 23 connecting the first side surface 21 and the second side surface 22. Therefore, the outlet 32 can be made larger than the case where the outlet 32 is formed on the first side surface 21 or the second side surface 22. In the first embodiment, the air outlet 32 extends in the width direction of the housing 20. In this case, the air blown out from the outlet 32 is wide, so that the momentum is weak and the speed is low. Therefore, even if the user in the air-conditioned space is exposed to air, it is possible to prevent the user from being impaired in comfort.
　また、筐体２０には、第１の吸込口３１ａと吹出口３２とを接続し、第１の送風機１２ａから熱交換器１１に向かって空気が流れる第１の通風路３４が形成されている。そして、筐体２０には、第２の吸込口３１ｂと吹出口３２とを接続し、第２の送風機１２ｂから熱交換器１１に向かって空気が流れる第２の通風路３５と、が形成されている。そして、第１の送風機１２ａ及び第２の送風機１２ｂは、遠心送風機又は斜流送風機であり、第１の通風路３４及び第２の通風路３５は、熱交換器１１よりも接続面２３側に形成されている。このように、第１の送風機１２ａ及び第２の送風機１２ｂが熱交換器１１よりも側方に配置されているため、第１の送風機１２ａ及び第２の送風機１２ｂには、比較的大径の送風機を用いることができる。従って、騒音を低減し、性能を向上させることができる。 Further, the housing 20 is formed with a first ventilation passage 34 in which the first suction port 31a and the air outlet 32 are connected and air flows from the first blower 12a toward the heat exchanger 11. .. Then, the housing 20 is formed with a second ventilation passage 35 in which the second suction port 31b and the air outlet 32 are connected and air flows from the second blower 12b toward the heat exchanger 11. ing. The first blower 12a and the second blower 12b are centrifugal blowers or mixed flow blowers, and the first ventilation passage 34 and the second ventilation passage 35 are closer to the connection surface 23 than the heat exchanger 11. It is formed. As described above, since the first blower 12a and the second blower 12b are arranged on the side of the heat exchanger 11, the first blower 12a and the second blower 12b have a relatively large diameter. A blower can be used. Therefore, noise can be reduced and performance can be improved.
　更に、接続面２３は、上面２４及び下面２５を有し、吹出口３２は、上面２４に形成された上部吹出口３２ａと、下面２５に形成された下部吹出口３２ｂと、を含む。そして、筐体２０には、上部吹出口３２ａと下部吹出口３２ｂとを接続する吹出風路３３が形成されている。このため、冷房時の冷気又は暖房時の暖気は、上部吹出口３２ａ及び下部吹出口３２ｂのいずれもから吹き出される。よって、空調対象空間の下部又は上部に、冷気又は暖気が滞留することを抑制することができる。従って、室内機３は、空調対象空間を迅速に所望の温度に調整することができる。 Further, the connecting surface 23 has an upper surface 24 and a lower surface 25, and the outlet 32 includes an upper outlet 32a formed on the upper surface 24 and a lower outlet 32b formed on the lower surface 25. The housing 20 is formed with an outlet air passage 33 that connects the upper outlet 32a and the lower outlet 32b. Therefore, the cold air during cooling or the warm air during heating is blown out from both the upper outlet 32a and the lower outlet 32b. Therefore, it is possible to prevent cold air or warm air from staying in the lower or upper part of the air-conditioned space. Therefore, the indoor unit 3 can quickly adjust the air-conditioned space to a desired temperature.
実施の形態２．
　図５は、実施の形態２に係る室内機１０３を示す上面断面図である。本実施の形態２は、熱交換器１１１の形状が、実施の形態１と相違する。本実施の形態２では、実施の形態１と共通する部分は同一の符号を付して説明を省略し、実施の形態１との相違点を中心に説明する。 Embodiment 2.
FIG. 5 is a top sectional view showing the indoor unit 103 according to the second embodiment. In the second embodiment, the shape of the heat exchanger 111 is different from that of the first embodiment. In the second embodiment, the parts common to the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and the differences from the first embodiment will be mainly described.
　図５に示すように、熱交換器１１１が幅方向において傾斜している。具体的には、熱交換器１１１の端部から中央部にかけてフィン１１１ａが外側に広がっている。これにより、第１の通風路３４及び第２の通風路３５は、熱交換器１１１の幅方向の中央に向かうに従って狭くなっている。 As shown in FIG. 5, the heat exchanger 111 is inclined in the width direction. Specifically, the fins 111a extend outward from the end to the center of the heat exchanger 111. As a result, the first ventilation passage 34 and the second ventilation passage 35 become narrower toward the center in the width direction of the heat exchanger 111.
　第１の送風機１２ａ及び第２の送風機１２ｂから流出した空気は、第１の通風路３４及び第２の通風路３５をとおって熱交換器１１１に流入する。その際、熱交換器１１１の両端部において、空気は、第１の通風路３４及び第２の通風路３５から直ちに熱交換器１１１に流入する。そして、空気は、熱交換器１１１の中央部において、第１の通風路３４及び第２の通風路３５をある程度通過した後に熱交換器１１１に流入する。このため、熱交換器１１１の中央部における空気の速度は、熱交換器１１１の両端部における空気の速度よりも速い場合がある。 The air flowing out from the first blower 12a and the second blower 12b flows into the heat exchanger 111 through the first ventilation passage 34 and the second ventilation passage 35. At that time, at both ends of the heat exchanger 111, air immediately flows into the heat exchanger 111 from the first ventilation passage 34 and the second ventilation passage 35. Then, the air flows into the heat exchanger 111 after passing through the first ventilation passage 34 and the second ventilation passage 35 to some extent in the central portion of the heat exchanger 111. Therefore, the velocity of air in the central portion of the heat exchanger 111 may be faster than the velocity of air in both ends of the heat exchanger 111.
　本実施の形態２では、第１の通風路３４及び第２の通風路３５は、熱交換器１１１の幅方向の中央に向かうに従って狭くなっている。このため、第１の通風路３４及び第２の通風路３５は、熱交換器１１１の中央部において風路面積が大きく、熱交換器１１１の両端部において風路面積が小さい。よって、熱交換器１１１の中央部において速度が速い空気は、風路面積が小さいことによって減速する。これにより、熱交換器１１１を通過する空気の幅方向の風速分布を均一化させることができる。よって、空気が熱交換器１１１を通過する際に発生する圧力損失を低減させることができる。これにより、室内機１０３は、第１の送風機１２ａ及び第２の送風機１２ｂの動力の増大、風量の減少及び運転騒音の増大を抑制することができる。 In the second embodiment, the first ventilation passage 34 and the second ventilation passage 35 become narrower toward the center in the width direction of the heat exchanger 111. Therefore, the first ventilation passage 34 and the second ventilation passage 35 have a large air passage area at the central portion of the heat exchanger 111 and a small air passage area at both ends of the heat exchanger 111. Therefore, the air having a high velocity in the central portion of the heat exchanger 111 is decelerated due to the small air passage area. As a result, the wind speed distribution in the width direction of the air passing through the heat exchanger 111 can be made uniform. Therefore, the pressure loss generated when the air passes through the heat exchanger 111 can be reduced. As a result, the indoor unit 103 can suppress an increase in power, a decrease in air volume, and an increase in operating noise of the first blower 12a and the second blower 12b.
　また、これにより、上部吹出口３２ａ及び下部吹出口３２ｂから吹き出される空気の幅方向の風速分布も均一化される。このため、気流の制御性が向上し、使用者の快適性が向上する。なお、第１の送風機１２ａ及び第２の送風機１２ｂから第１の通風路３４及び第２の通風路３５に流入する空気の高さ方向の分布がばらついている場合、熱交換器１１１が高さ方向において傾斜していてもよい。この場合、熱交換器１１１が曲げられてもよいし、プレート上の熱交換器１１１が複数枚設置されてもよい。 Further, as a result, the wind speed distribution in the width direction of the air blown from the upper outlet 32a and the lower outlet 32b is also made uniform. Therefore, the controllability of the air flow is improved, and the comfort of the user is improved. When the distribution of the air flowing from the first blower 12a and the second blower 12b into the first ventilation passage 34 and the second ventilation passage 35 in the height direction varies, the heat exchanger 111 has a height. It may be tilted in the direction. In this case, the heat exchanger 111 may be bent, or a plurality of heat exchangers 111 on the plate may be installed.
　（第１変形例）
　図６は、実施の形態２の第１変形例に係る室内機２０３を示す上面断面図である。第１変形例は、熱交換器２１１の複数のフィン２１１ａの間隔が実施の形態１と相違する。図６に示すように、複数のフィン２１１ａは、熱交換器２１１の中央部の間隔が狭く、熱交換器２１１の両端部の間隔が広い。これにより、熱交換器２１１の中央部を通過する空気の圧力損失が大きくなり、熱交換器２１１の両端部を通過する空気の圧力損失が小さくなる。 (First modification)
FIG. 6 is a top sectional view showing the indoor unit 203 according to the first modification of the second embodiment. In the first modification, the distance between the plurality of fins 211a of the heat exchanger 211 is different from that of the first embodiment. As shown in FIG. 6, in the plurality of fins 211a, the distance between the central portions of the heat exchanger 211 is narrow, and the distance between both end portions of the heat exchanger 211 is wide. As a result, the pressure loss of the air passing through the central portion of the heat exchanger 211 becomes large, and the pressure loss of the air passing through both end portions of the heat exchanger 211 becomes small.
　前述の如く、熱交換器２１１の中央部における空気の速度は、熱交換器２１１の両端部における空気の速度よりも速い場合がある。この場合、熱交換器２１１の中央部において速度が速い空気は、熱交換器２１１における圧力損失が大きい部分を通過するため、減速する。これにより、熱交換器２１１を通過する空気の幅方向の風速分布を均一化させることができる。 As described above, the velocity of air at the central portion of the heat exchanger 211 may be faster than the velocity of air at both ends of the heat exchanger 211. In this case, the air having a high speed in the central portion of the heat exchanger 211 passes through the portion of the heat exchanger 211 where the pressure loss is large, and thus decelerates. As a result, the wind speed distribution in the width direction of the air passing through the heat exchanger 211 can be made uniform.
　（第２変形例）
　図７は、実施の形態２の第２変形例に係る室内機３０３を示す上面断面図である。第２変形例は、室内機３０３が内部ベーン３４０を備えている点で実施の形態１と相違する。図７に示すように、内部ベーン３４０は、第１の通風路３４及び第２の通風路３５における熱交換器１１の端部側に設けられ、空気の向きを調整する。このように、内部ベーン３４０は、熱交換器１１の上流側に設けられている。これにより、第１の通風路３４及び第２の通風路３５に流れる空気の向きは、内部ベーン３４０によって熱交換器１１に流入する方向に変えられる。このため、熱交換器１１の両端部を通過する空気の速度が速くなる。 (Second modification)
FIG. 7 is a top sectional view showing the indoor unit 303 according to the second modification of the second embodiment. The second modification is different from the first embodiment in that the indoor unit 303 includes an internal vane 340. As shown in FIG. 7, the internal vane 340 is provided on the end side of the heat exchanger 11 in the first ventilation passage 34 and the second ventilation passage 35 to adjust the direction of air. As described above, the internal vane 340 is provided on the upstream side of the heat exchanger 11. As a result, the direction of the air flowing through the first ventilation passage 34 and the second ventilation passage 35 is changed to the direction in which the air flows into the heat exchanger 11 by the internal vane 340. Therefore, the speed of air passing through both ends of the heat exchanger 11 becomes high.
　前述の如く、熱交換器１１の中央部における空気の速度は、熱交換器１１の両端部における空気の速度よりも速い場合がある。内部ベーン３４０によって、熱交換器１１の両端部を通過する空気の速度が速くなるため、熱交換器１１を通過する空気の幅方向の風速分布を均一化させることができる。これにより、空気が熱交換器１１を通過する際に発生する圧力損失を低減させることができる。これにより、第１の送風機１２ａ及び第２の送風機１２ｂの動力の増大、風量の減少及び運転騒音の増大を抑制することができる。 As described above, the velocity of air in the central portion of the heat exchanger 11 may be faster than the velocity of air in both ends of the heat exchanger 11. Since the internal vane 340 increases the velocity of the air passing through both ends of the heat exchanger 11, the wind velocity distribution in the width direction of the air passing through the heat exchanger 11 can be made uniform. This makes it possible to reduce the pressure loss that occurs when air passes through the heat exchanger 11. As a result, it is possible to suppress an increase in power, a decrease in air volume, and an increase in operating noise of the first blower 12a and the second blower 12b.
　（第３変形例）
　図８は、実施の形態２の第３変形例に係る室内機４０３を示す上面断面図である。第３変形例は、室内機４０３が仕切板４５０を備えている点で実施の形態１と相違する。図８に示すように、仕切板４５０は、熱交換器１１の幅方向の中央部に対向する位置に設けられ、第１の通風路３４と第２の通風路３５とを区画する部材である。これにより、第１の通風路３４に流れる空気と、第２の通風路３５に流れる空気とが、熱交換器１１の中央部に対向する位置において衝突することを回避することができる。このため、空気同士が衝突して混合することによって発生する圧力損失を、低減することができる。従って、第１の送風機１２ａ及び第２の送風機１２ｂの動力の増大、風量の減少及び運転騒音の増大を抑制することができる。 (Third modification example)
FIG. 8 is a top sectional view showing an indoor unit 403 according to a third modification of the second embodiment. The third modification is different from the first embodiment in that the indoor unit 403 is provided with the partition plate 450. As shown in FIG. 8, the partition plate 450 is provided at a position facing the central portion in the width direction of the heat exchanger 11, and is a member that separates the first ventilation passage 34 and the second ventilation passage 35. .. As a result, it is possible to prevent the air flowing through the first ventilation passage 34 and the air flowing through the second ventilation passage 35 from colliding with each other at a position facing the central portion of the heat exchanger 11. Therefore, the pressure loss generated by the collision and mixing of air can be reduced. Therefore, it is possible to suppress an increase in power, a decrease in air volume, and an increase in operating noise of the first blower 12a and the second blower 12b.

　図９は、実施の形態３に係る室内機５０３を示す側面断面図である。本実施の形態３は、上部ベーン５６０ａ及び下部ベーン５６０ｂを備えている点で、実施の形態１と相違する。本実施の形態３では、実施の形態１と共通する部分は同一の符号を付して説明を省略し、実施の形態１との相違点を中心に説明する。 Embodiment 3.
FIG. 9 is a side sectional view showing the indoor unit 503 according to the third embodiment. The third embodiment is different from the first embodiment in that the upper vane 560a and the lower vane 560b are provided. In the third embodiment, the parts common to the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and the differences from the first embodiment will be mainly described.
　図９に示すように、上部ベーン５６０ａは、上面２４に設けられ、上部吹出口３２ａから吹き出される空気の向きを調整する。また、下部ベーン５６０ｂは、下面２５に設けられ、下部吹出口３２ｂから吹き出される空気の向きを調整する。ここで、上部ベーン５６０ａ及び下部ベーン５６０ｂは、それぞれ独立に駆動するように構成されてもよい。この場合、室内機５０３は、上部吹出口３２ａから吹き出される空気の向きと、下部吹出口３２ｂから吹き出される空気の向きとを独立に制御することができる。従って、気流の制御性が向上し、使用者の快適性が向上する。 As shown in FIG. 9, the upper vane 560a is provided on the upper surface 24 and adjusts the direction of the air blown out from the upper air outlet 32a. Further, the lower vane 560b is provided on the lower surface 25 and adjusts the direction of the air blown from the lower outlet 32b. Here, the upper vane 560a and the lower vane 560b may be configured to be driven independently of each other. In this case, the indoor unit 503 can independently control the direction of the air blown from the upper outlet 32a and the direction of the air blown from the lower outlet 32b. Therefore, the controllability of the air flow is improved, and the comfort of the user is improved.
　また、例えば冷房運転時に、室内機５０３は、下部ベーン５６０ｂを閉じて下部吹出口３２ｂを閉止し、上部ベーン５６０ａを開いて上部吹出口３２ａを開放する。冷却された空気は、概して、空調対象空間の下部に滞留する。冷房運転時に、上部吹出口３２ａのみから冷却された空気が吹き出されるため、空調対象空間の温度を迅速に均一化させることができる。この場合、空調対象空間の温度が均一化された後、室内機５０３は下部ベーン５６０ｂを開いて下部吹出口３２ｂを開放する。 Further, for example, during the cooling operation, the indoor unit 503 closes the lower vane 560b to close the lower air outlet 32b, opens the upper vane 560a to open the upper air outlet 32a. The cooled air generally stays in the lower part of the air-conditioned space. Since the cooled air is blown out only from the upper air outlet 32a during the cooling operation, the temperature of the air-conditioned space can be quickly made uniform. In this case, after the temperature of the air-conditioned space is made uniform, the indoor unit 503 opens the lower vane 560b and opens the lower air outlet 32b.
　また、例えば暖房運転時に、室内機５０３は、上部ベーン５６０ａを閉じて上部吹出口３２ａを閉止し、下部ベーン５６０ｂを開いて下部吹出口３２ｂを開放する。加熱された空気は、概して、空調対象空間の上部に滞留する。暖房運転時に、下部吹出口３２ｂのみから加熱された空気が吹き出されるため、空調対象空間の温度を迅速に均一化させることができる。この場合、空調対象空間の温度が均一化された後、室内機５０３は、上部ベーン５６０ａを開いて上部吹出口３２ａを開放する。従って、本実施の形態３によれば、気流の制御性を損なわずに、空調対象空間の温度を迅速に均一化させることができる。 Further, for example, during the heating operation, the indoor unit 503 closes the upper vane 560a, closes the upper air outlet 32a, opens the lower vane 560b, and opens the lower air outlet 32b. The heated air generally stays in the upper part of the air-conditioned space. Since the heated air is blown out only from the lower air outlet 32b during the heating operation, the temperature of the air-conditioned space can be quickly made uniform. In this case, after the temperature of the air-conditioned space is made uniform, the indoor unit 503 opens the upper vane 560a and opens the upper air outlet 32a. Therefore, according to the third embodiment, the temperature of the air-conditioned space can be quickly made uniform without impairing the controllability of the air flow.
実施の形態４．
　図１０は、実施の形態４に係る室内機６０３を示す側面断面図である。本実施の形態４は、補助ベーン６７０を備えている点で、実施の形態３と相違する。本実施の形態４では、実施の形態１と共通する部分は同一の符号を付して説明を省略し、実施の形態３との相違点を中心に説明する。 Embodiment 4.
FIG. 10 is a side sectional view showing the indoor unit 603 according to the fourth embodiment. The fourth embodiment is different from the third embodiment in that it includes an auxiliary vane 670. In the fourth embodiment, the parts common to the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and the differences from the third embodiment will be mainly described.
　図１０に示すように、補助ベーン６７０は、吹出風路３３に設けられ、空気の向きを調整する。補助ベーン６７０は、熱交換器１１の下流側に設けられており、前面２６側の熱交換器１１と背面２７側の熱交換器１１に複数配置されている。熱交換器１１を通過した空気の向きは、補助ベーン６７０によって、上部吹出口３２ａ又は下部吹出口３２ｂ側に変えられる。その際、前面２６側の熱交換器１１を通過した空気の向きと、背面２７側の熱交換器１１を通過した空気の向きとが相違してもよい。これにより、例えば前面２６側の熱交換器１１に流れる空気の向きが補助ベーン６７０によって上部吹出口３２ａ側に変えられ、空気は上部吹出口３２ａから吹き出される。また、背面２７側の熱交換器１１に流れる空気の向きが補助ベーン６７０によって下部吹出口３２ｂ側に変えられ、空気は下部吹出口３２ｂから吹き出される。このように、室内機６０３が補助ベーン６７０を備えることによって、上部ベーン５６０ａ及び下部ベーン５６０ｂにおける気流の制御性が向上する。 As shown in FIG. 10, the auxiliary vane 670 is provided in the blowout air passage 33 and adjusts the direction of the air. Auxiliary vanes 670 are provided on the downstream side of the heat exchanger 11, and a plurality of auxiliary vanes 670 are arranged on the heat exchanger 11 on the front surface 26 side and the heat exchanger 11 on the back surface 27 side. The direction of the air that has passed through the heat exchanger 11 is changed to the upper outlet 32a or the lower outlet 32b side by the auxiliary vane 670. At that time, the direction of the air passing through the heat exchanger 11 on the front surface 26 side and the direction of the air passing through the heat exchanger 11 on the back surface 27 side may be different. As a result, for example, the direction of the air flowing through the heat exchanger 11 on the front surface 26 side is changed to the upper outlet 32a side by the auxiliary vane 670, and the air is blown out from the upper outlet 32a. Further, the direction of the air flowing through the heat exchanger 11 on the back surface 27 side is changed to the lower outlet 32b side by the auxiliary vane 670, and the air is blown out from the lower outlet 32b. As described above, when the indoor unit 603 is provided with the auxiliary vane 670, the controllability of the airflow in the upper vane 560a and the lower vane 560b is improved.
　図１１は、実施の形態４に係る室内機６０３を示す側面断面図である。補助ベーン６７０は、吹出風路３３において、前面２６側の熱交換器１１及び背面２７側の熱交換器１１の近傍に設けられ、吹出風路３３のうち前面２６側の熱交換器１１及び背面２７側の熱交換器１１から離れた位置には、補助ベーン６７０が設けられていない。そして、前面２６側の熱交換器１１を通過する空気の向きと背面２７側の熱交換器１１を通過する空気の向きとが同一となるように補助ベーン６７０が制御され、上部ベーン５６０ａ及び下部ベーン５６０ｂが開放されてもよい。 FIG. 11 is a side sectional view showing the indoor unit 603 according to the fourth embodiment. The auxiliary vane 670 is provided in the vicinity of the heat exchanger 11 on the front surface 26 side and the heat exchanger 11 on the back surface 27 side in the outlet air passage 33, and the heat exchanger 11 and the back surface on the front surface 26 side of the outlet air passage 33 are provided. An auxiliary vane 670 is not provided at a position away from the heat exchanger 11 on the 27 side. Then, the auxiliary vane 670 is controlled so that the direction of the air passing through the heat exchanger 11 on the front surface 26 side and the direction of the air passing through the heat exchanger 11 on the back surface 27 side are the same, and the upper vane 560a and the lower portion are controlled. The vane 560b may be opened.
　この場合、図１１に示すように、熱交換器１１を通過した空調空気ＡＡの向きは、補助ベーン６７０によって上部吹出口３２ａ側又は下部吹出口３２ｂ側に変えられる。このため、空気は、吹出風路３３における前面２６側の熱交換器１１及び背面２７側の熱交換器１１の近傍のみに流れる。このとき、吹出風路３３における前面２６側の熱交換器１１及び背面２７側の熱交換器１１の近傍のみに流れる空気は、粘性によって、吹出風路３３のうち前面２６側の熱交換器１１及び背面２７側の熱交換器１１から離れた位置に滞留する空気を引きずり込む。これにより、吹出風路３３のうち前面２６側の熱交換器１１及び背面２７側の熱交換器１１から離れた位置に滞留する空気も、吹出風路３３における前面２６側の熱交換器１１及び背面２７側の熱交換器１１の近傍のみに流れる空気と同じ方向に流れる。 In this case, as shown in FIG. 11, the direction of the conditioned air AA that has passed through the heat exchanger 11 is changed to the upper outlet 32a side or the lower outlet 32b side by the auxiliary vane 670. Therefore, the air flows only in the vicinity of the heat exchanger 11 on the front surface 26 side and the heat exchanger 11 on the back surface 27 side in the blowout air passage 33. At this time, the air flowing only in the vicinity of the heat exchanger 11 on the front surface 26 side and the heat exchanger 11 on the back surface 27 side in the blowout air passage 33 is viscous, and the heat exchanger 11 on the front surface 26 side of the blowout air passage 33 And the air staying at a position away from the heat exchanger 11 on the back surface 27 side is dragged. As a result, the air staying at a position away from the heat exchanger 11 on the front surface 26 side and the heat exchanger 11 on the back surface 27 side of the blowout air passage 33 also becomes the heat exchanger 11 on the front surface 26 side and the heat exchanger 11 on the front surface 26 side in the blowout air passage 33. It flows in the same direction as the air that flows only in the vicinity of the heat exchanger 11 on the back surface 27 side.
　この場合、上部ベーン５６０ａ及び下部ベーン５６０ｂは開いている。例えば、上部吹出口３２ａから熱交換された空調空気ＡＡが吹き出される場合、空調対象空間の空気ＲＡが、熱交換された空調空気ＡＡの粘性に引きずられて、下部吹出口３２ｂから吹出風路３３に流入する。そして、流入した空気ＲＡは、上部吹出口３２ａから、熱交換された空調空気ＡＡと共に吹き出される。また例えば、下部吹出口３２ｂから熱交換された空調空気ＡＡが吹き出される場合、空調対象空間の空気ＲＡが、熱交換された空調空気ＡＡの粘性に引きずられて、上部吹出口３２ａから吹出風路３３に流入する。そして、流入した空気ＲＡは、下部吹出口３２ｂから、熱交換された空調空気ＡＡと共に吹き出される。 In this case, the upper vane 560a and the lower vane 560b are open. For example, when the heat-exchanged air-conditioned air AA is blown out from the upper air outlet 32a, the air RA in the air-conditioned space is dragged by the viscosity of the heat-exchanged air-conditioned air AA and is blown out from the lower air outlet 32b. It flows into 33. Then, the inflowing air RA is blown out from the upper air outlet 32a together with the heat-exchanged conditioned air AA. Further, for example, when the heat-exchanged air-conditioned air AA is blown out from the lower outlet 32b, the air RA in the air-conditioned space is dragged by the viscosity of the heat-exchanged air-conditioned air AA and blown out from the upper air outlet 32a. It flows into the road 33. Then, the inflowing air RA is blown out from the lower outlet 32b together with the heat-exchanged conditioned air AA.
　このように、本実施の形態４によれば、室内機６０３は、第１の送風機１２ａ及び第２の送風機１２ｂの回転駆動より生じた風量よりも多い風量を得ることができる。このように、空調対象空間の空気が、上部吹出口３２ａ及び下部吹出口３２ｂを介して空調対象空間内を循環するため、空調対象空間の温度を迅速に均一化させることができ、使用者の快適性を向上させることができる。 As described above, according to the fourth embodiment, the indoor unit 603 can obtain a larger air volume than the air volume generated by the rotational drive of the first blower 12a and the second blower 12b. In this way, the air in the air-conditioned space circulates in the air-conditioned space via the upper air outlet 32a and the lower air outlet 32b, so that the temperature of the air-conditioned space can be quickly made uniform and the user can use it. Comfort can be improved.
実施の形態５．
　図１２は、実施の形態５に係る室内機７０３を示す上面断面図である。本実施の形態５は、第１の送風機１２ａ及び第２の送風機１２ｂを回転駆動するモータ７１３が一つである点で、実施の形態１と相違する。本実施の形態５では、実施の形態１と共通する部分は同一の符号を付して説明を省略し、実施の形態１との相違点を中心に説明する。 Embodiment 5.
FIG. 12 is a top sectional view showing the indoor unit 703 according to the fifth embodiment. The fifth embodiment is different from the first embodiment in that the motor 713 for rotationally driving the first blower 12a and the second blower 12b is one. In the fifth embodiment, the parts common to the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and the differences from the first embodiment will be mainly described.
　図１２に示すように、第１の送風機１２ａ及び第２の送風機１２ｂは、室内機７０３の奥行方向の中央に対して対称の位置に配置されている。そして、第１の送風機１２ａ及び第２の送風機１２ｂは、同一の駆動シャフト７１６によって接続され、単一のモータ７１３によって駆動シャフト７１６が回転駆動されることにより、回転駆動する。このように、室内機７０３は、単一のモータ７１３によって実現されるため、モータ７１３の個数を減らすことによって生産性が向上する。 As shown in FIG. 12, the first blower 12a and the second blower 12b are arranged at positions symmetrical with respect to the center in the depth direction of the indoor unit 703. Then, the first blower 12a and the second blower 12b are connected by the same drive shaft 716, and the drive shaft 716 is rotationally driven by a single motor 713 to rotationally drive the drive shaft 716. As described above, since the indoor unit 703 is realized by a single motor 713, the productivity is improved by reducing the number of motors 713.
　なお、第１の送風機１２ａの第１の翼１５ａの回転方向と第２の送風機１２ｂの第２の翼１５ｂの回転方向とが反対であるように構成されてもよい。即ち、この場合、筐体２０の第１の端部側の外側から第１の送風機１２ａをみた場合と、筐体２０の第２の端部側の外側から第２の送風機１２ｂをみた場合とで、第１の送風機１２ａ及び第２の送風機１２ｂの回転方向が反対である。これにより、筐体２０内に、第１の送風機１２ａ及び第２の送風機１２ｂの第１の翼１５ａ及び第２の翼１５ｂの回転方向に回転して発生する空気の渦が、外側からみて逆方向の回転であるため、内部で同方向の回転となる。この場合、第１の送風機１２ａによって生じる渦と、第２の送風機１２ｂによって生じる渦とが衝突しても、渦の方向が同じであるため、騒音の発生を抑制することができる。 The rotation direction of the first blade 15a of the first blower 12a and the rotation direction of the second blade 15b of the second blower 12b may be opposite to each other. That is, in this case, the case where the first blower 12a is viewed from the outside on the first end side of the housing 20 and the case where the second blower 12b is viewed from the outside on the second end side of the housing 20. The rotation directions of the first blower 12a and the second blower 12b are opposite to each other. As a result, the vortex of air generated by rotating the first blade 15a and the second blade 15b of the first blower 12a and the second blower 12b in the rotation direction in the housing 20 is reversed when viewed from the outside. Since it is a rotation in a direction, it is internally rotated in the same direction. In this case, even if the vortex generated by the first blower 12a and the vortex generated by the second blower 12b collide, the direction of the vortex is the same, so that the generation of noise can be suppressed.
