Description

空気調和機の室内機Air conditioner indoor unit
　本発明は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.
　空気調和機の室内機には、ファンと、ファンに送風された空気と熱交換する熱交換器と、空気の吸入口及び吹出口が形成され、ファン及び熱交換器を収容するケーシングと、を備えるものがある。このような室内機は、熱交換された空気を吹出口から所望の方向に送風するため、ベーンを備えることがある。 The indoor unit of the air conditioner includes a fan, a heat exchanger that exchanges heat with the air blown to the fan, and a casing that is formed with an air inlet and outlet and that houses the fan and the heat exchanger. There is something to prepare. Such an indoor unit may include a vane in order to blow heat-exchanged air in a desired direction from the air outlet.
　例えば、特許文献１には、長手方向が左右方向に延在する吹出口が下部の前面側に形成されたケーシングを備える空気調和機の室内機が開示されている。吹出口には、長手方向を左右方向に向けた状態で、板面の向きを上下方向に可動させる矩形状の上下ベーンが設けられている。そして、上下ベーンは、ファンと同数個だけ設けられている。 For example, Patent Document 1 discloses an indoor unit of an air conditioner including a casing in which a blowout port whose longitudinal direction extends in the left-right direction is formed on the lower front side. The blower outlet is provided with rectangular upper and lower vanes that move the plate surface in the vertical direction with the longitudinal direction directed in the horizontal direction. The same number of upper and lower vanes as the fans are provided.
　また、特許文献２には、吹出口に設けられ、前後方向に並べられた複数個の矩形状の上下ベーンを備える空気調和機の室内機が開示されている。 Further, Patent Document 2 discloses an indoor unit of an air conditioner provided with a plurality of rectangular upper and lower vanes arranged at the outlet and arranged in the front-rear direction.
　特許文献３には、吹出口に設けられ、板面の向きを左右方向に可動させる複数個の板状の左右ベーンを備える空気調和機の室内機が開示されている。 Patent Document 3 discloses an indoor unit of an air conditioner that includes a plurality of plate-like left and right vanes that are provided at an air outlet and move the direction of a plate surface in the left-right direction.

　特許文献１－３に記載の、空気調和機の室内機では、長手方向が左右方向に延在する形状に吹出口が形成されている場合に、ファンから吹出口中央までの距離とファンから吹出口端部までの距離とが異なってしまう。このため、吹出口内の位置によって風量がばらつくことがある。その結果、上下ベーン又は左右ベーンで気流を十分に制御できないことがある。 In the indoor unit of an air conditioner described in Patent Literature 1-3, when the air outlet is formed in a shape in which the longitudinal direction extends in the left-right direction, the distance from the fan to the center of the air outlet and the fan from the air outlet The distance to the exit end will be different. For this reason, the air volume may vary depending on the position in the outlet. As a result, the airflow may not be sufficiently controlled by the upper and lower vanes or the left and right vanes.
　本発明は上記の課題を解決するためになされたもので、吹出口から吹き出される空気の気流方向を高い精度で制御することができる、空気調和機の室内機を提供することを目的とする。 This invention was made in order to solve said subject, and it aims at providing the indoor unit of an air conditioner which can control the airflow direction of the air which blows off from a blower outlet with high precision. .
　上記の目的を達成するため、本発明に係る空気調和機の室内機は、上部に吸入口が形成され、下部の前面側に吹出口が形成されたケーシングと、ケーシング内の吸入口よりも下側に設けられ、吹出口の側へ送風する軸流型又は斜流型のファンと、ケーシング内のファンよりも下側に設けられ、ファンに送風された空気と熱交換する熱交換器と、吹出口に設けられ、板面の向きを上下方向に変化させて熱交換器で熱交換された空気の気流方向を変更する上下ベーンと、を備える。吹出口は、長手方向が左右方向に延在する形状に形成されている。上下ベーンは、熱交換器で熱交換された空気の気流方向に長い長羽根部と、長手方向に長羽根部と並べられ、長羽根部よりも気流方向に短い短羽根部と、を有する。 In order to achieve the above object, an indoor unit of an air conditioner according to the present invention includes a casing in which an inlet is formed in the upper part and a blower outlet is formed in the lower front side, and a lower part than the inlet in the casing. An axial flow type or mixed flow type fan that is provided on the side and blows air to the outlet side, and a heat exchanger that is provided below the fan in the casing and exchanges heat with the air blown to the fan, And an upper and lower vane that is provided at the air outlet and changes the direction of the plate surface in the vertical direction and changes the airflow direction of the air heat-exchanged by the heat exchanger. The blower outlet is formed in a shape whose longitudinal direction extends in the left-right direction. The upper and lower vanes have long blade portions that are long in the air flow direction of the air heat-exchanged by the heat exchanger, and short blade portions that are aligned with the long blade portions in the longitudinal direction and shorter in the air flow direction than the long blade portions.
　本発明の構成によれば、上下ベーンが、ファンから送風される空気の気流方向に長い長羽根部と、吹出口の長手方向に長羽根部と並べられ、長羽根部よりも気流方向に短い短羽根部と、を有する。このため、吹出口の気流が強い部分で長羽根部が気流の方向を変更し、吹出口の気流が弱い部分で短羽根部が気流の方向を変更することができる。その結果、空気の気流方向を高い精度で制御することができる。 According to the configuration of the present invention, the upper and lower vanes are aligned with the long blade portion that is long in the airflow direction of the air blown from the fan and the long blade portion in the longitudinal direction of the air outlet, and are shorter in the airflow direction than the long blade portion. Short blade portion. For this reason, a long blade part can change the direction of an airflow in the part where the airflow of a blower outlet is strong, and a short blade part can change the direction of an airflow in a part where the airflow of a blower outlet is weak. As a result, the airflow direction can be controlled with high accuracy.

In the orthogonal coordinate system XYZ shown in the figure, with the air outlet of the indoor unit of the air conditioner in front, the horizontal direction is the X axis, the vertical direction is the Z axis, and the direction orthogonal to the X axis and the Z axis is Y Is the axis. Hereinafter, this coordinate system will be described as appropriate.
　実施の形態に係る空気調和機の室内機は、空気の吸入口と吹出口が形成されたケーシングを備えている。そして、吹出口には、吹出口から吹き出される空気の気流方向を、吹出口内部の位置によらないで特定の方向に向ける制御をするため、長羽根部及び短羽根部を有する上下ベーンが設けられている。以下に、図１－図３を参照して空気調和機の室内機の構成について説明する。 The indoor unit of the air conditioner according to the embodiment includes a casing in which an air inlet and an air outlet are formed. And the upper and lower vanes having the long blade portion and the short blade portion are provided at the air outlet in order to control the air flow direction of the air blown from the air outlet in a specific direction without depending on the position inside the air outlet. Is provided. The configuration of the indoor unit of the air conditioner will be described below with reference to FIGS.
　図１は本発明の実施の形態に係る空気調和機の室内機１Ａの斜視図である。図２は図１に示すII-II切断線の断面図である。図３は、図１に示すIII-III切断線の断面図である。なお、図１及び図２では、理解を容易にするため、室内機１Ａが備える左右ベーンを省略している。
　図１－図３に示すように、空気調和機の室内機１Ａは、吸入口１１及び吹出口１２を有するケーシング１０と、ケーシング１０に収容され、吸入口１１から空気を吸入するファン２０と、ファン２０が吸入した空気と熱交換する熱交換器３０と、吹出口１２に設けられ、吹出口１２から吹き出される空気の吹き出し方向を定める上下ベーン４０及び左右ベーン５０と、で構成されている。 FIG. 1 is a perspective view of an indoor unit 1A of an air conditioner according to an embodiment of the present invention. 2 is a cross-sectional view taken along the line II-II shown in FIG. 3 is a cross-sectional view taken along the line III-III shown in FIG. In FIGS. 1 and 2, the left and right vanes provided in the indoor unit 1A are omitted for easy understanding.
As shown in FIG. 1 to FIG. 3, an indoor unit 1A for an air conditioner includes a casing 10 having an inlet 11 and an outlet 12; a fan 20 that is accommodated in the casing 10 and sucks air from the inlet 11; The heat exchanger 30 that exchanges heat with the air sucked by the fan 20, and the upper and lower vanes 40 and the left and right vanes 50 that are provided at the air outlet 12 and define the blowing direction of the air blown out from the air outlet 12 are configured. .
　ケーシング１０は、図１に示すように、長手方向をＸ方向に向けた直方体状に形成されている。そして、ケーシング１０の上面には、装置内に空気を吸い込むための吸入口１１が形成されている。 As shown in FIG. 1, the casing 10 is formed in a rectangular parallelepiped shape whose longitudinal direction is in the X direction. A suction port 11 for sucking air into the apparatus is formed on the upper surface of the casing 10.
　吸入口１１は、複数個、Ｘ方向に並べられて形成されている。吸入口１１それぞれは、円形状に形成されている。そして、吸入口１１から－Ｚ方向には、円筒状に形成された、図示しない内壁が延在している。その内壁の円筒空間には、図２に示すように、ファン２０が配置されている。 A plurality of suction ports 11 are formed in the X direction. Each of the suction ports 11 is formed in a circular shape. Then, an inner wall (not shown) formed in a cylindrical shape extends in the −Z direction from the suction port 11. A fan 20 is disposed in the cylindrical space of the inner wall as shown in FIG.
　ファン２０は、軸流型又は斜流型のファンで構成されている。ここで、軸流型又は斜流型のファンとは、羽根を回転させて羽根の軸方向に、又は軸方向に斜めに、気流を発生させるファンのことである。ファン２０は、上述した吸入口１１それぞれに配置されている。そして、ファン２０は、図示しないモータによって回転する。その結果、ファン２０は、吸入口１１それぞれからケーシング１０内に空気を吸入する。 The fan 20 is an axial flow type or a mixed flow type fan. Here, the axial flow type or diagonal flow type fan is a fan that generates airflow in the axial direction of the blades or obliquely in the axial direction by rotating the blades. The fan 20 is arrange | positioned at each suction port 11 mentioned above. The fan 20 is rotated by a motor (not shown). As a result, the fan 20 sucks air into the casing 10 from each of the suction ports 11.
　ケーシング１０の内部には、図１に示すように、気流の乱れを防止するため、ファン２０とファン２０との間を仕切る仕切り板１３が設けられている。その仕切り板１３は、ケーシング１０の＋Ｚ内壁からケーシング１０内に収容された熱交換器３０の＋Ｚ面まで延在している。ファン２０は、仕切り板１３で仕切られた空間それぞれに、吸入した空気を送風する。これにより、ファン２０は、熱交換器３０に吸入した空気を送風する。 As shown in FIG. 1, a partition plate 13 that partitions between the fan 20 and the fan 20 is provided in the casing 10 in order to prevent airflow disturbance. The partition plate 13 extends from the + Z inner wall of the casing 10 to the + Z surface of the heat exchanger 30 accommodated in the casing 10. The fan 20 blows the sucked air into each space partitioned by the partition plate 13. Thereby, the fan 20 blows the air sucked into the heat exchanger 30.
　熱交換器３０は、図示しないが、冷媒が流れる伝熱管と、伝熱管の外周に沿って配置された螺旋状のフィンと、を有する、いわゆるフィンチューブ型の形状に形成されている。そして、熱交換器３０は、図２に示すように、ファン２０よりも－Ｚ側に配置されている。熱交換器３０は、ファン２０から送風された空気を通りやすくするため、ＹＺ断面視で、＋Ｚ側に、すなわち、ファン２０側に、鋭角を有する形状に折り曲げられている。熱交換器３０は、ファン２０から送風される空気と冷媒とを熱交換させて、その空気の温度、湿度等を調整する。 Although not shown, the heat exchanger 30 is formed in a so-called fin tube shape having a heat transfer tube through which a refrigerant flows and helical fins arranged along the outer periphery of the heat transfer tube. The heat exchanger 30 is arranged on the −Z side with respect to the fan 20 as shown in FIG. The heat exchanger 30 is bent into a shape having an acute angle on the + Z side, that is, on the fan 20 side in a YZ cross-sectional view so that air blown from the fan 20 can easily pass through. The heat exchanger 30 exchanges heat between the air blown from the fan 20 and the refrigerant, and adjusts the temperature, humidity, and the like of the air.
　図１に戻って、ケーシング１０の正面側の下部には、装置内に吸い込まれた空気を吹き出すための吹出口１２が形成されている。吹出口１２は、正面視で長手方向がＸ方向に、すなわち、左右方向に向いた長方形の形状に形成されている。上述した、熱交換器３０によって調整された空気は、吹出口１２から装置の外に吹き出される。吹出口１２には、図１－図３に示すように、上述した複数の上下ベーン４０及び複数の左右ベーン５０が配置されている。 Returning to FIG. 1, an air outlet 12 is formed at the lower part on the front side of the casing 10 to blow out the air sucked into the apparatus. The blower outlet 12 is formed in a rectangular shape whose longitudinal direction is in the X direction, that is, in the left-right direction when viewed from the front. The air adjusted by the heat exchanger 30 described above is blown out of the apparatus from the blowout port 12. As shown in FIGS. 1 to 3, the plurality of upper and lower vanes 40 and the plurality of left and right vanes 50 are arranged at the outlet 12.
　複数の上下ベーン４０は、吹出口１２から吹き出る空気の気流方向を上下方向に変更して制御する部材である。複数の上下ベーン４０は、図２に示すように、Ｙ方向に並べられて設けられている。 The plurality of upper and lower vanes 40 are members that change and control the airflow direction of the air blown from the outlet 12 in the vertical direction. The plurality of upper and lower vanes 40 are arranged in the Y direction as shown in FIG.
　各上下ベーン４０は、図１に示すように、長手方向をＸ方向に向け、短手方向に湾曲した板の形状に形成されている。各上下ベーン４０の短手方向の一方の端部、すなわち、＋Ｚ端は、吹出口１２内に配置されている。そして、各上下ベーン４０は、その＋Ｚ端から、吹出口１２を通って吹出口１２の外まで延在している。図示しないが、各上下ベーン４０の＋Ｚ端側には、Ｘ方向に延在する軸部が設けられ、それら軸部が吹出口１２の内壁に回動可能に保持されている。そして、それら軸部が図示しないモータによって回動することで、各上下ベーン４０は軸部の回りに回動する。その結果、各上下ベーン４０は揺動して、各上下ベーン４０の板面の向きが上下方向に変化する。これにより、各上下ベーン４０は、吹出口１２から吹き出される空気の気流方向を変更して制御している。 As shown in FIG. 1, each of the upper and lower vanes 40 is formed in the shape of a plate that has a longitudinal direction in the X direction and is curved in the short direction. One end of each upper and lower vane 40 in the short direction, that is, the + Z end is disposed in the air outlet 12. Each upper and lower vane 40 extends from the + Z end to the outside of the air outlet 12 through the air outlet 12. Although not shown, shaft portions extending in the X direction are provided on the + Z end sides of the upper and lower vanes 40, and these shaft portions are rotatably held on the inner wall of the air outlet 12. Then, the upper and lower vanes 40 are rotated around the shaft portions by the shaft portions being rotated by a motor (not shown). As a result, each upper and lower vane 40 swings, and the direction of the plate surface of each upper and lower vane 40 changes in the vertical direction. Thereby, each upper and lower vane 40 changes and controls the airflow direction of the air which blows off from the blower outlet 12. FIG.
　また、各上下ベーン４０は、図１に示すように、吹出口１２の長手方向、すなわち、Ｘ方向の位置に応じて、吹き出される空気の気流方向がばらつくことを防止するため、Ｘ方向に、複数の長羽根部４１と複数の短羽根部４２とが並べられることで組み立てられている。換言すると、複数の長羽根部４１と複数の短羽根部４２とが、一枚の板状の上下ベーン４０を形成している。

In addition, as shown in FIG. 1, each upper and lower vane 40 is arranged in the X direction in order to prevent the airflow direction of the blown air from varying depending on the longitudinal direction of the outlet 12, that is, the position in the X direction. The plurality of long blade portions 41 and the plurality of short blade portions 42 are assembled and arranged. In other words, the plurality of long blade portions 41 and the plurality of short blade portions 42 form a single plate-like upper and lower vanes 40.

　各長羽根部４１は、Ｚ方向に各短羽根部４２よりも長い板の形状に形成されている。そして、各長羽根部４１と各短羽根部４２は、図示しないが、＋Ｚ端の位置がＸ方向に揃えられている。このため、各長羽根部４１は、各短羽根部４２よりも－Ｚ方向に延在している。 Each long blade portion 41 is formed in a plate shape longer than each short blade portion 42 in the Z direction. And although each long blade part 41 and each short blade part 42 are not shown in figure, the position of + Z end is aligned in the X direction. Therefore, each long blade part 41 extends in the −Z direction from each short blade part 42.
　各長羽根部４１は、風速が大きく、風量が多い箇所の空気の気流方向を変化させるため、ファン２０に対して－Ｚ方向に配置されている。これに対して、各短羽根部４２は、各長羽根部４１よりも風速が小さく、風量が少ない箇所の空気の気流方向を変化させるため、ファン２０とファン２０の間かつファン２０よりも－Ｚ側に配置されている。そして、上下ベーン４０全体では、空気調和機の室内機１Ａにファン２０が３つ存在するため、４つの短羽根部４２と３つの長羽根部４１が、＋Ｘ方向に、短羽根部４２、長羽根部４１、短羽根部４２・・の順序で並べられている。これにより、風速が大きく、風量が多い箇所を流れる空気は、より長く上下ベーン４０の板面に沿って流れる。風速が小さく、風量が少ない箇所を流れる空気は、より短く上下ベーン４０の板面に沿って流れる。その結果、気流方向が各長羽根部４１と各短羽根部４２の板面の方向に確実かつ正確に変更される。 Each long blade portion 41 is arranged in the −Z direction with respect to the fan 20 in order to change the air flow direction of the air at a location where the wind speed is large and the air volume is large. On the other hand, each short blade portion 42 has a lower wind speed than each long blade portion 41 and changes the air flow direction of the air at a portion where the air volume is small. Arranged on the Z side. In the entire upper and lower vanes 40, since there are three fans 20 in the indoor unit 1A of the air conditioner, the four short blade portions 42 and the three long blade portions 41 are arranged in the + X direction, The blades 41 and the short blades 42 are arranged in this order. As a result, the air flowing through the portion where the wind speed is large and the air volume is large flows along the plate surface of the upper and lower vanes 40 for a longer time. The air flowing through the portion where the wind speed is low and the air volume is small flows along the plate surface of the upper and lower vanes 40 shorter. As a result, the airflow direction is reliably and accurately changed in the direction of the plate surface of each long blade portion 41 and each short blade portion 42.
　一方、複数の左右ベーン５０は、吹出口１２から吹き出される空気の気流方向を所望の左右方向に変更して制御する部材である。複数の左右ベーン５０は、ファン２０と同数だけ設けられている。各左右ベーン５０は、図３に示すように、平板状の複数の長ベーン５１と、平板状の複数の短ベーン５２と、で構成されている。 On the other hand, the plurality of left and right vanes 50 are members that change and control the airflow direction of the air blown out from the air outlet 12 to a desired left and right direction. The same number of left and right vanes 50 as the fans 20 are provided. As shown in FIG. 3, each of the left and right vanes 50 includes a plurality of flat long vanes 51 and a plurality of flat short vanes 52.
　各長ベーン５１と各短ベーン５２は、矩形の板状に形成されている。そして、各長ベーン５１と各短ベーン５２の板面は、ＸＹ平面に垂直に向けられている。図示しないが、各長ベーン５１と各短ベーン５２の長手方向は、空気の気流方向を左右方向に向けるため、後述するリンク部材５３によって、Ｙ方向に平行又は斜めに向けられている。また、短手方向は、Ｚ方向に向けられている。そして、図３に示すように、各長ベーン５１は、各短ベーン５２よりもＺ方向に長い。各長ベーン５１の＋Ｚ端と－Ｚ端は、各短ベーン５２の＋Ｚ端と－Ｚ端よりも、＋Ｚ側と－Ｚ側に延在している。各長ベーン５１は、風速が大きく、風量が多い箇所の空気の気流方向を変化させるため、ファン２０のＸ方向中央に対して－Ｚ方向に配置されている。各短ベーン５２は、より風速が小さく、風量が少ない箇所の空気の気流方向を変化させるため、ファン２０のＸ方向中央よりもＸ方向にずれた位置に配置されている。そして、左右ベーン５０全体では、各長ベーン５１と各短ベーン５２が、＋Ｘ方向から、短ベーン５２、長ベーン５１、長ベーン５１、短ベーン５２の順序で配置されている。これにより、気流方向が各長ベーン５１と各短ベーン５２の板面の方向に確実かつ正確に変更される。 Each long vane 51 and each short vane 52 are formed in a rectangular plate shape. The plate surfaces of each long vane 51 and each short vane 52 are oriented perpendicular to the XY plane. Although not shown, the longitudinal direction of each long vane 51 and each short vane 52 is directed parallel or obliquely to the Y direction by a link member 53 described later in order to direct the airflow direction in the left-right direction. The short direction is directed to the Z direction. As shown in FIG. 3, each long vane 51 is longer in the Z direction than each short vane 52. The + Z end and the −Z end of each long vane 51 extend to the + Z side and the −Z side from the + Z end and −Z end of each short vane 52. Each long vane 51 is arranged in the −Z direction with respect to the center in the X direction of the fan 20 in order to change the air flow direction of the air at a location where the wind speed is large and the air volume is large. Each short vane 52 is arranged at a position shifted in the X direction from the center in the X direction of the fan 20 in order to change the air flow direction of the air at a portion where the wind speed is lower and the air volume is smaller. In the left and right vanes 50 as a whole, the long vanes 51 and the short vanes 52 are arranged in the order of the short vanes 52, the long vanes 51, the long vanes 51, and the short vanes 52 from the + X direction. Thereby, the air flow direction is reliably and accurately changed to the plate surface directions of the long vanes 51 and the short vanes 52.
　また、各長ベーン５１と各短ベーン５２のＺ方向中央は、その板面の向きを変えて気流方向を変更するため、リンク部材５３によって連結されている。図示しないが、リンク部材５３は、複数の棒状部材で構成されている。各長ベーン５１と各短ベーン５２は、リンク部材５３の棒状部材が図示しないモータで可動することにより、板面の向きを左右方向に変化させる。これにより、各長ベーン５１と各短ベーン５２は、気流方向を所望の左右方向に変化させている。 Further, the center in the Z direction of each long vane 51 and each short vane 52 is connected by a link member 53 in order to change the airflow direction by changing the direction of the plate surface. Although not shown, the link member 53 is composed of a plurality of rod-shaped members. Each long vane 51 and each short vane 52 change the direction of the plate surface in the left-right direction by moving the rod-shaped member of the link member 53 with a motor (not shown). Thereby, each long vane 51 and each short vane 52 is changing the airflow direction to the desired left-right direction.
　次に、空気調和機の室内機１Ａの動作について説明する。以下の説明では、吹出口１２から吹き出される空気の気流方向を所望の方向にするため、上述したモータによって各上下ベーン４０の軸部が回動されている。その結果、図１に示す向きに各上下ベーン４０の板面が向けられているものとする。また、リンク部材５３のモータによって、リンク部材５３の棒状部材が可動されている。その結果、図３に示す向きに各長ベーン５１と各短ベーン５２の板面が向けられているものとする。 Next, the operation of the indoor unit 1A of the air conditioner will be described. In the following description, the shaft portion of each upper and lower vane 40 is rotated by the motor described above in order to change the airflow direction of the air blown out from the outlet 12 to a desired direction. As a result, it is assumed that the plate surfaces of the upper and lower vanes 40 are oriented in the direction shown in FIG. Further, the rod-shaped member of the link member 53 is moved by the motor of the link member 53. As a result, it is assumed that the plate surfaces of the long vanes 51 and the short vanes 52 are directed in the direction shown in FIG.
　ファン２０がモータによって正方向に回転すると、装置の外の空気が吸入口１１から吸入される。吸入された空気は、仕切り板１３で仕切られたケーシング１０内の空間を通って－Ｚ方向に流れる。そして、空気は、熱交換器３０に触れて熱交換器３０内の冷媒と熱交換する。 When the fan 20 is rotated in the forward direction by the motor, air outside the apparatus is sucked from the suction port 11. The sucked air flows in the −Z direction through the space in the casing 10 partitioned by the partition plate 13. The air touches the heat exchanger 30 to exchange heat with the refrigerant in the heat exchanger 30.
　熱交換された空気は、ケーシング１０内の熱交換器３０よりも－Ｚ側の空間に流れる。ケーシング１０内では、図２に示すように、吹出口１２に向かって延在する風路１４が形成されている。空気の風速は、風路１４の形状に応じた風速に変化する。また、気流方向も風路１４の形状に応じた向きとなる。そして、熱交換された空気は、その風速と気流方向で、吹出口１２まで流れる。 The air subjected to heat exchange flows into a space on the −Z side with respect to the heat exchanger 30 in the casing 10. In the casing 10, as shown in FIG. 2, an air passage 14 extending toward the air outlet 12 is formed. The wind speed of the air changes to a wind speed corresponding to the shape of the air path 14. In addition, the airflow direction is also in accordance with the shape of the air passage 14. Then, the heat-exchanged air flows to the air outlet 12 at the wind speed and the airflow direction.
　吹出口１２では、気流方向は、概ねＹＺ平面に平行である。吹出口１２には、複数の上下ベーン４０があるため、空気は、複数の上下ベーン４０に沿って流れる。その結果、気流方向は各上下ベーン４０の板面の方向に変化する。各上下ベーン４０では、ファン２０の－Ｚ方向に位置する、風速が大きく風量が多い箇所に、各長羽根部４１が配置されている。また、各長羽根部４１は、上下ベーン４０に沿って流れる前の気流方向に長い。ファン２０とファン２０の間かつファン２０の－Ｚ側に位置する、風速が小さく風量が少ない箇所に、各短羽根部４２が配置されている。このため、風速が大きい箇所では、風速が小さい箇所よりも、より長く上下ベーン４０に沿って空気が流れる。その結果、風速が大きい箇所では、気流が各上下ベーン４０の形状の影響を大きく受ける。これにより、気流方向が各上下ベーン４０の板面方向に変化する。このため、風速の大小にかかわらず気流方向が各上下ベーン４０の板面方向となる。その結果、吹出口１２全体で気流方向が高い精度で制御される。 At the air outlet 12, the airflow direction is generally parallel to the YZ plane. Since the blower outlet 12 has a plurality of upper and lower vanes 40, air flows along the plurality of upper and lower vanes 40. As a result, the airflow direction changes in the direction of the plate surface of each upper and lower vane 40. In each of the upper and lower vanes 40, each long blade portion 41 is disposed at a location in the −Z direction of the fan 20 where the wind speed is large and the air volume is large. Each long blade portion 41 is long in the direction of airflow before flowing along the upper and lower vanes 40. Each short blade portion 42 is arranged at a location between the fans 20 and the fan 20 and on the −Z side of the fan 20 where the wind speed is small and the air volume is small. For this reason, air flows along the upper and lower vanes 40 at a location where the wind speed is high, longer than at a location where the wind speed is low. As a result, the airflow is greatly affected by the shape of each upper and lower vane 40 at locations where the wind speed is high. As a result, the airflow direction changes in the plate surface direction of each of the upper and lower vanes 40. For this reason, the airflow direction becomes the plate surface direction of each upper and lower vane 40 regardless of the wind speed. As a result, the air flow direction is controlled with high accuracy in the entire outlet 12.
　また、吹出口１２には、複数の左右ベーン５０があるため、空気は、複数の上下ベーン４０に沿うだけでなく、複数の左右ベーン５０に沿って流れる。各左右ベーン５０では、ファン２０の－Ｚ方向の、風速が大きく風量が多い箇所に、各長ベーン５１が配置されている。また、各長ベーン５１は、左右ベーン５０に沿って流れる前の気流方向に、すなわち、Ｚ方向に長い。ファン２０とファン２０の間かつファン２０の－Ｚ側の、風速が小さく風量が少ない箇所には、各短ベーン５２が配置されている。このため、風速が大きい箇所では、風速が小さい箇所よりも、より長く左右ベーン５０に沿って空気が流れる。その結果、複数の上下ベーン４０の場合と同様に、風速の大小にかかわらず気流方向が複数の左右ベーン５０の板面方向となる。これにより、吹出口１２全体で気流方向が高い精度で制御される。 Further, since the outlet 12 has a plurality of left and right vanes 50, the air flows not only along the plurality of upper and lower vanes 40 but also along the plurality of left and right vanes 50. In each left and right vane 50, each long vane 51 is disposed at a location in the −Z direction of the fan 20 where the wind speed is large and the air volume is large. Each long vane 51 is long in the direction of airflow before flowing along the left and right vanes 50, that is, in the Z direction. Each short vane 52 is arranged between the fans 20 and between the fans 20 and on the −Z side of the fan 20 at a location where the wind speed is small and the air volume is small. For this reason, air flows along the left and right vanes 50 longer at locations where the wind speed is high than at locations where the wind speed is low. As a result, as in the case of the plurality of upper and lower vanes 40, the airflow direction becomes the plate surface direction of the plurality of left and right vanes 50 regardless of the magnitude of the wind speed. Thereby, the air flow direction is controlled with high accuracy in the entire outlet 12.
　以上のように、実施の形態に係る空気調和機の室内機１Ａでは、上下ベーン４０が熱交換器３０で熱交換された空気の気流方向に長い長羽根部４１と、長羽根部４１よりも短い短羽根部４２と、を有している。このため、吹出口１２の気流が強い箇所に長羽根部４１を配置し、気流がより弱い箇所に短羽根部４２を配置することで、気流方向を所望の上下方向に確実かつ正確に変更することができる。その結果、空気調和機の室内機１Ａでは、気流方向を高い精度で制御できる。換言すると、気流の制御性が高い。 As described above, in the indoor unit 1A of the air conditioner according to the embodiment, the upper and lower vanes 40 are longer than the long blade part 41 and the long blade part 41 that are long in the airflow direction of the heat exchanged by the heat exchanger 30. Short short blade portion 42. For this reason, the long blade part 41 is arrange | positioned in the location where the airflow of the blower outlet 12 is strong, and the short blade part 42 is arrange | positioned in the location where an airflow is weaker, and changes an airflow direction to a desired up-down direction reliably and correctly. be able to. As a result, the air flow direction can be controlled with high accuracy in the indoor unit 1A of the air conditioner. In other words, airflow controllability is high.
