Description

空気調和機の室内機Indoor unit of air conditioner
　本発明は、遠心ファンおよび遠心ファンを駆動するモータを備え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 provided with a centrifugal fan and a motor for driving the centrifugal fan.
　空気調和機の室内機は、例えば特許文献１に開示されているように、内部に送風機を備えている。上記室内機は、送風機を回転させることにより、吸込み口から吸い込んだ空気を、熱交換器を介して、吹出し口から吹き出す。 The indoor unit of the air conditioner is internally provided with a blower as disclosed in, for example, Patent Document 1. The indoor unit rotates the blower to blow out the air sucked from the suction port from the blowout port through the heat exchanger.
　近年の空気調和機には、空気調和機能に加えて空気清浄機能を備えたものが開発されている。例えばＨＥＰＡフィルタ（High Efficiency Particulate Air Filter）は通風抵抗が大きく、空気清浄にＨＥＰＡフィルタを使用した場合には、吹出し口から吹き出す空気の風量が大幅に低下する。そこで、空気清浄にＨＥＰＡフィルタを使用する場合には、十分な風量（十分な空気の吸込み量）を確保する必要がある。 In recent years, in addition to the air conditioning function, air conditioners having an air cleaning function have been developed. For example, the HEPA filter (High Efficiency Particulate Air Filter) has a large ventilation resistance, and when the HEPA filter is used for air cleaning, the volume of air blown out from the outlet is significantly reduced. Therefore, when using a HEPA filter for air cleaning, it is necessary to secure a sufficient air volume (a sufficient amount of air suction).
　一般的な空気調和機では、送風機として、クロスフローファンと称される横断流ファンを用いている。しかしながら、十分な風量を得るためには、送風機として、シロッコファンと称される遠心ファンを用いることが好ましい。 In a general air conditioner, a cross flow fan called a cross flow fan is used as a blower. However, in order to obtain a sufficient air flow, it is preferable to use a centrifugal fan called a sirocco fan as a blower.
　特許文献１には、軸方向に、それぞれケーシング内に配置された遠心ファンを２つ配置し、２つのケーシングの間に設けられたモータで、２つの遠心ファンを回転する空気調和機の室内機が開示されている。 In Patent Document 1, an indoor unit of an air conditioner in which two centrifugal fans respectively disposed in a casing are disposed in an axial direction, and a motor provided between two casings rotates the two centrifugal fans. Is disclosed.

　しかしながら、特許文献１では、２つのケーシングの間は仕切り材で仕切られており、各ケーシングの吸込部から吸入した空気を、遠心ファンの回転により加速して、各ケーシングの吐出部から吐出する。このため、特許文献１の構成では、モータの上方および下方に無駄なスペースが存在する。 However, in Patent Document 1, two casings are partitioned by a partition material, and the air taken in from the suction portion of each casing is accelerated by the rotation of the centrifugal fan and discharged from the discharge portion of each casing. Therefore, in the configuration of Patent Document 1, useless space exists above and below the motor.
　本発明の一態様は、遠心ファンを駆動するモータの上方または下方のスペースを、遠心ファンの空気の吸い込みに利用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。 An aspect of the present invention aims to provide an indoor unit of an air conditioner in which a space above or below a motor for driving a centrifugal fan can be used for suction of air of the centrifugal fan.
　上記の課題を解決するために、本発明の一態様にかかる空気調和機の室内機は、空気を吸込む吸込み口を少なくとも１つ有する筐体内に、左右方向に複数配列された遠心ファンと、上記遠心ファンを回転駆動させる駆動軸を左右に有し、隣り合う遠心ファン間に配置されたモータと、上記モータの外周面の一部を覆うモータカバーと、を備え、上記モータカバーは、上記吸込み口に向かって突出して設けられた壁体を少なくとも１つ有し、上記壁体は、上記吸込み口との対向面から上記駆動軸の軸方向の一方の側面に繋がる風路を形成する第１開口部と、上記第１開口部と隔壁で分離され、上記吸込み口との対向面から上記駆動軸の軸方向の他方の側面に繋がる風路を形成する第２開口部と、を有している。 In order to solve the above-mentioned subject, an indoor unit of an air conditioner concerning one mode of the present invention has a centrifugal fan arranged in multiple numbers in a horizontal direction in a case which has at least one suction opening which sucks in air, and the above The motor cover has a drive shaft for driving to rotate the centrifugal fans on the left and right, and a motor disposed between the adjacent centrifugal fans, and a motor cover that covers a part of the outer peripheral surface of the motor. A first air passage having at least one wall provided projecting toward the mouth, the wall forming an air passage connected to a side face in the axial direction of the drive shaft from a surface opposite to the suction opening An opening, and a second opening separated from the first opening and the partition wall and forming an air passage connected from the opposite surface to the suction port to the other side surface in the axial direction of the drive shaft; There is.
　本発明の一態様によれば、遠心ファンを駆動するモータの上方または下方のスペースを、遠心ファンの空気の吸い込みに利用することができる空気調和機の室内機を提供することができる。 According to one aspect of the present invention, it is possible to provide an indoor unit of an air conditioner in which the space above or below the motor for driving the centrifugal fan can be used for suction of air of the centrifugal fan.

　室内機本体部２の上部には、第１吸込み口１１が設けられている。室内機本体部２の下部には、第２吸込み口１２が設けられている。室内機本体部２の前部には、吹出し口１７が設けられている。室内機本体部２は、第１吸込み口１１の内側（下側）に、第１フィルタ１５を有し、第２吸込み口１２の内側（上側）に第２フィルタ１６を有している。第１フィルタ１５は、例えばプレフィルタに相当する機能を有するフィルタであり、第２フィルタ１６よりも低性能であり、第２フィルタ１６よりも通風抵抗が小さいフィルタである。第２フィルタ１６は、例えばＨＥＰＡフィルタ（High Efficiency Particulate Air Filter）であり、第１フィルタ１５よりも高性能であり、第１フィルタ１５よりも通風抵抗が大きいフィルタである。 A first suction port 11 is provided at the top of the indoor unit body 2. A second suction port 12 is provided at the lower part of the indoor unit body 2. At the front of the indoor unit body 2, a blowoff port 17 is provided. The indoor unit body 2 has a first filter 15 on the inner side (lower side) of the first suction port 11 and has a second filter 16 on the inner side (upper side) of the second suction port 12. The first filter 15 is, for example, a filter having a function equivalent to a prefilter, is a filter that has lower performance than the second filter 16, and has a smaller ventilation resistance than the second filter 16. The second filter 16 is, for example, a HEPA filter (High Efficiency Particulate Air Filter), which is a filter that has higher performance than the first filter 15 and has a larger ventilation resistance than the first filter 15.
　第１吸込み口１１から室内機１に吸い込まれた空気は、第１フィルタ１５を経た後、送風ファン４１により熱交換器１４へ吹き付けられ、吹出し口１７から吹き出される。第２吸込み口１２から室内機１に吸い込まれた空気は、第２フィルタ１６を経た後、送風ファン４１により熱交換器１４へ吹き付けられ、吹出し口１７から吹き出される。なお、送風機１３の詳細については後述する。 The air sucked into the indoor unit 1 from the first suction port 11 passes through the first filter 15 and is then blown to the heat exchanger 14 by the blower fan 41 and blown out from the blowout port 17. The air sucked into the indoor unit 1 from the second suction port 12 passes through the second filter 16 and is then blown to the heat exchanger 14 by the blower fan 41 and blown out from the blowout port 17.

　図５および図６に示すように、送風機１３は、２つの送風ファン４１と、図示しない２つのファンケーシング４７（図２参照）と、ファンモータ５１（モータ）と、モータカバー５０と、を備えている。 As shown in FIGS. 5 and 6, the blower 13 includes two blower fans 41, two fan casings 47 (see FIG. 2) not shown, a fan motor 51 (motor), and a motor cover 50. ing.
　２つの送風ファン４１は、キャビネット３０内に、室内機１の長手方向に沿って、左右方向に並設されている。図２に示すように、各ファンケーシング４７は、それぞれ、各送風ファン４１の外周面の一部を覆っている。図３、図４、図５の（ａ）～（ｃ）、および図６の（ａ）～（ｃ）に示すように、モータカバー５０は、ファンモータ５１の外周面の一部を覆っている。 The two blower fans 41 are arranged in the cabinet 30 in the lateral direction along the longitudinal direction of the indoor unit 1. As shown in FIG. 2, each fan casing 47 covers a part of the outer peripheral surface of each blower fan 41. As shown in FIGS. 3, 4 and 5 (a) to (c) and 6 (a) to (c), the motor cover 50 covers a part of the outer peripheral surface of the fan motor 51. There is.
　以下、２つの送風ファン４１を区別する必要がある場合には、ファンモータ５１の左側の送風ファン４１を第１送風ファン４１ａと称し、ファンモータ５１の右側の送風ファン４１を第２送風ファン４１ｂと称する。一方、第１送風ファン４１ａと第２送風ファン４１ｂとを特に区別する必要がないときは、これら第１送風ファン４１ａおよび第２送風ファン４１ｂを、それぞれ、単に送風ファン４１と記す。 Hereinafter, when it is necessary to distinguish the two blower fans 41, the blower fan 41 on the left side of the fan motor 51 is referred to as the first blower fan 41a, and the blower fan 41 on the right side of the fan motor 51 is the second blower fan 41b. It is called. On the other hand, when it is not necessary to distinguish the first blower fan 41a and the second blower fan 41b, the first blower fan 41a and the second blower fan 41b are simply referred to as the blower fan 41, respectively.
　ファンモータ５１と２つの送風ファン４１とは、室内機１の長手方向に沿って直列に接続して配置されている。ファンモータ５１は、円筒形状を有するモータ本体５２の左右の端面にそれぞれ駆動軸５３を有する両軸モータである。 The fan motor 51 and the two blower fans 41 are connected in series along the longitudinal direction of the indoor unit 1 and arranged. The fan motor 51 is a double-axis motor having drive shafts 53 on the left and right end faces of a cylindrical motor body 52.
　ファンモータ５１は、左右に隣り合う送風ファン４１の間に配置されており、駆動軸５３を介して、各送風ファン４１に、それぞれ回転力を伝達することで、各送風ファン４１を回転駆動する。図示はしないが、熱交換器１４は、送風機１３の前方に、２つの送風ファン４１に跨って配設される。 The fan motor 51 is disposed between the blower fans 41 adjacent to the left and right, and transmits rotational power to the blower fans 41 via the drive shaft 53 to rotationally drive the blower fans 41. . Although not shown, the heat exchanger 14 is disposed in front of the blower 13 so as to straddle the two blower fans 41.
　図５および図６に示すように、送風ファン４１は、２つの多翼ロータ４２（羽根車）を互いのディスク面４２ａで接続した構成のシロッコファン（遠心ファン）である。送風ファン４１としてシロッコファンを用いることで、クロスフローファンよりも大きい風量・風圧を得ることができる。 As shown in FIGS. 5 and 6, the blower fan 41 is a sirocco fan (centrifugal fan) having a configuration in which two multi-blade rotors 42 (impellers) are connected by the disk surfaces 42 a of each other. By using a sirocco fan as the blower fan 41, it is possible to obtain an air volume and pressure greater than that of the cross flow fan.
　送風ファン４１は、軸方向の両方の側面に開口部４４を有している。送風ファン４１は、所定の方向に多翼ロータ４２が回転することにより、多翼ロータ４２における、駆動軸５３に平行な方向の開口部４４から空気を吸込み、多翼ロータ４２の外周面（つまり、回転面）の開口部４５から空気を吹き出す。したがって、ファンケーシング４７には、送風ファン４１の開口部４４と対向する位置に、それぞれ開口部４８（図２参照）が形成されている。 The blower fan 41 has openings 44 on both side surfaces in the axial direction. The blower fan 41 sucks air from the opening 44 in the direction parallel to the drive shaft 53 in the multi-blade rotor 42 by rotation of the multi-blade rotor 42 in a predetermined direction, and the outer peripheral surface of the multi-blade rotor 42 (that is, , Air from the opening 45 of the rotational surface). Accordingly, openings 48 (see FIG. 2) are formed in the fan casing 47 at positions facing the openings 44 of the blower fan 41.

　また、各送風ファン４１は、ファンモータ５１の駆動軸５３を固定するためのボス４６を備えている。ボス４６は、例えばアルミニウム製の中空の直管で形成されている。ボス４６は、各多翼ロータ４２における開口部４４から一部突出するように形成されている。つまり、ボス４６は、多翼ロータ４２が回転する際に空気を吸込む、空気吸込み側の開口部４４から外側に突出するように形成されている。 Further, each blower fan 41 is provided with a boss 46 for fixing the drive shaft 53 of the fan motor 51. The boss 46 is formed of, for example, a hollow straight pipe made of aluminum. The bosses 46 are formed to partially project from the openings 44 in each multi-blade rotor 42. That is, the boss 46 is formed so as to project outside from the air intake side opening 44 that sucks in air when the multi-blade rotor 42 rotates.
　各駆動軸５３および各回転軸４３は、左右の送風ファン４１のボス４６にそれぞれ挿入されている。各駆動軸５３および各回転軸４３は、各ボス４６に、例えば図示しないネジで固定されている。これにより、各送風ファン４１の回転軸４３は、各ファンモータ５１の駆動軸５３と連結されている。 The drive shafts 53 and the rotation shafts 43 are respectively inserted into the bosses 46 of the left and right blower fans 41. Each drive shaft 53 and each rotation shaft 43 are fixed to each boss 46 by, for example, a screw (not shown). Thus, the rotary shaft 43 of each blower fan 41 is connected to the drive shaft 53 of each fan motor 51.
　ファンモータ５１の各駆動軸５３は、ボス４６を介して左右の送風ファン４１を回転可能に支持している。２個の送風ファン４１は、１個のファンモータ５１で駆動されて回転する。 The drive shafts 53 of the fan motor 51 rotatably support the left and right blower fans 41 via the bosses 46. The two blower fans 41 are driven by one fan motor 51 to rotate.
　モータ本体５２の左右の両端面から突出する駆動軸５３の周囲には、ファンモータ５１の振動の伝達を防止する防振材として、円盤状の防振ゴム５４が設けられている。 A disk-shaped anti-vibration rubber 54 is provided around the drive shafts 53 protruding from both left and right end surfaces of the motor main body 52 as a vibration-proof material for preventing transmission of the vibration of the fan motor 51.

　下部モータカバー６０および上部モータカバー７０は、例えば樹脂で形成されている。図７の（ｂ）および図８の（ａ）・（ｂ）に示すように、モータ収容部６１の両端面には、ファンモータ５１の左右の防振ゴム５４が嵌め込まれる半円弧状の切欠部６１ｂが形成されている。切欠部６１ｂは、防振ゴム５４の外周の下半分の形状に合わせて切り欠かれている。モータ収容部７１の両端面には、ファンモータ５１の左右の防振ゴム５４が嵌め込まれる半円弧状の切欠部７１ｂが形成されている。切欠部７１ｂは、防振ゴム５４の外周の上半分の形状に合わせて切り欠かれている。切欠部６１ｂ・７１ｂは、下部モータカバー６０と上部モータカバー７０とを組み合わせることにより、防振ゴム５４とほぼ同じ大きさの円形状の穴になる。 The lower motor cover 60 and the upper motor cover 70 are formed of, for example, a resin. As shown in (b) of FIG. 7 and (a) and (b) of FIG. 8, semicircular arc shaped notches in which the anti-vibration rubbers 54 of the fan motor 51 are fitted on both end surfaces of the motor housing 61 The portion 61 b is formed. The notch 61 b is cut out in accordance with the shape of the lower half of the outer periphery of the vibration-proof rubber 54. On both end surfaces of the motor housing portion 71, semicircular arc-shaped cutouts 71b into which the left and right vibration isolation rubbers 54 of the fan motor 51 are fitted are formed. The cutout portion 71 b is cut out in accordance with the shape of the upper half of the outer periphery of the vibration-proof rubber 54. By combining the lower motor cover 60 and the upper motor cover 70, the notch portions 61b and 71b become circular holes having substantially the same size as the vibration-proof rubber 54.
　ファンモータ５１の左右の防振ゴム５４を上部モータカバー７０と下部モータカバー６０とで上下方向に挟み込むことで、モータカバー５０は、ファンモータ５１を支持している。ファンモータ５１は、左右の防振ゴム５４のみでモータカバー５０と接触している。ファンモータ５１の駆動軸５３は、切欠部６１ｂ・７１ｂを通してモータカバー５０の外に引き出されている。 The motor cover 50 supports the fan motor 51 by sandwiching the left and right anti-vibration rubbers 54 of the fan motor 51 in the vertical direction by the upper motor cover 70 and the lower motor cover 60. The fan motor 51 is in contact with the motor cover 50 only with the left and right anti-vibration rubbers 54. The drive shaft 53 of the fan motor 51 is pulled out of the motor cover 50 through the notches 61 b and 71 b.
　また、モータ収容部７１の上面の中央部には、図８の（ａ）～（ｃ）に示すように、駆動軸５３に直交する方向に沿って、帯状に開口部７１ｃが設けられている。このため、モータ本体５２の上面の一部は、開口部７１ｃから露出している。なお、図示はしないが、モータ収容部６１の下面の中央部にも、駆動軸５３に直交する方向に沿って、図示しない帯状の開口部が設けられている。モータ本体５２の下面の一部は、モータ収容部６１の下面の中央部に設けられた図示しない開口部から露出している。 Further, as shown in (a) to (c) of FIG. 8, a band-like opening 71 c is provided in the center of the upper surface of the motor housing 71 along the direction orthogonal to the drive shaft 53. . For this reason, a part of the top surface of the motor main body 52 is exposed from the opening 71 c. Although not shown, a belt-like opening (not shown) is also provided at the center of the lower surface of the motor housing 61 along the direction orthogonal to the drive shaft 53. A portion of the lower surface of the motor main body 52 is exposed from an opening (not shown) provided at the center of the lower surface of the motor housing 61.
　壁体７３は、第１吸込口１１からキャビネット３０内に吸い込んだ空気の流れを、隣り合う送風ファン４１の一方に向う流れと他方に向う流れとに分離してそれぞれの送風ファン４１に導く分離壁兼導風壁として機能する。また、壁体７３は、モータカバー５０とキャビネット３０とを固定する固定部材として機能する。 The wall body 73 separates the flow of air sucked into the cabinet 30 from the first suction port 11 into a flow toward one of the adjacent blower fans 41 and a flow toward the other and separates the flows into the respective blower fans 41 It acts as a wall and a guiding wall. The wall 73 also functions as a fixing member for fixing the motor cover 50 and the cabinet 30.
　壁体７３には、モータカバー５０を正面から見たときの奥行き方向に、該奥行き方向の中央部を境にして手前側の右側面の一部が縦方向に切り欠かれた第１開口部７４と、奥側の左側面の一部が縦方向に切り欠かれた第２開口部７５と、が設けられている。なお、モータカバー５０を正面から見たときの奥行き方向とは、室内機１の前面側から背面側に向かう方向を示す。 The wall 73 has a first opening in which a part of the right side on the near side is cut in the vertical direction with the central portion in the depth direction in the depth direction when the motor cover 50 is viewed from the front. 74 and a second opening 75 in which a part of the left side surface on the back side is cut away in the vertical direction. The depth direction when the motor cover 50 is viewed from the front indicates the direction from the front side to the back side of the indoor unit 1.
　第１開口部７４と第２開口部７５とは、隔壁７３ａで分離されている。隔壁７３ａは、平面視で駆動軸５３と一直線上に位置するように、駆動軸５３に沿って開口部７１ｃを跨いでいる。このため、第１開口部７４は、隔壁７３ａを挟んで、第２開口部７５よりも、室内機１の前面側に位置している。第２開口部７５は、隔壁７３ａを挟んで、第１開口部７４よりも、室内機１の背面側に位置している。 The first opening 74 and the second opening 75 are separated by the partition wall 73 a. The partition wall 73a straddles the opening 71c along the drive shaft 53 so as to be positioned on a straight line with the drive shaft 53 in a plan view. Therefore, the first opening 74 is located on the front side of the indoor unit 1 with respect to the second opening 75, with the partition wall 73a interposed therebetween. The second opening 75 is located on the back side of the indoor unit 1 with respect to the first opening 74 with the partition wall 73 a interposed therebetween.
　第１開口部７４は、平面視で、隔壁７３ａを奥側の壁部として、右側面の一部が開口された枠形状（言い換えれば、溝形状）を有している。第２開口部７５は、平面視で、隔壁７３ａを手前側の壁部として、左側面の一部が開口された枠形状（言い換えれば、溝形状）を有している。このため、壁体７３は、平面視で略逆Ｓ字形状を有している。 The first opening 74 has a frame shape (in other words, a groove shape) in which a part of the right side surface is opened with the partition wall 73a as a wall portion on the back side in plan view. The second opening 75 has a frame shape (in other words, a groove shape) in which a part of the left side surface is opened with the partition wall 73a as a front wall portion in plan view. For this reason, the wall body 73 has a substantially reverse S-shape in plan view.
　図６に示すように、第１開口部７４は、駆動軸５３の軸方向において、駆動軸５３の右側に配置された第２送風ファン４１ｂの一方の開口部４４側が開放されている。第２開口部７５は、駆動軸５３の軸方向において、駆動軸５３の左側に配置された第１送風ファン４１ａの一方の開口部４４側が開放されている。なお、第１開口部７４および第２開口部７５は、駆動軸５３の軸方向において、隣り合う送風ファン４１の開口部４４に面していることが、より望ましい。 As shown in FIG. 6, in the first opening 74, one opening 44 side of the second blower fan 41 b disposed on the right side of the drive shaft 53 is opened in the axial direction of the drive shaft 53. In the second opening 75, one opening 44 side of the first blower fan 41a disposed on the left side of the drive shaft 53 is opened in the axial direction of the drive shaft 53. More preferably, the first opening 74 and the second opening 75 face the opening 44 of the adjacent blower fan 41 in the axial direction of the drive shaft 53.
　また、第１開口部７４および第２開口部７５は、縦方向において、室内機本体部２の第１吸込み口１１に面して設けられている。つまり、第１開口部７４および第２開口部７５の上面（つまり、上側の開口端面）は、それぞれ、室内機本体部２の第１吸込み口１１に面して設けられている。 Further, the first opening 74 and the second opening 75 are provided to face the first suction port 11 of the indoor unit body 2 in the vertical direction. That is, the upper surfaces (that is, the upper open end surfaces) of the first opening 74 and the second opening 75 are provided to face the first suction port 11 of the indoor unit body 2 respectively.
　第１開口部７４および第２開口部７５の上面である、第１吸込み口１１側の開口端面は、それぞれ、空気の取込み口として機能する。また、第１開口部７４および第２開口部７５における、各送風ファン４１の開口部４４側の開口端面は、空気の取出口として機能する。 The opening end faces on the first suction port 11 side, which are the upper surfaces of the first opening 74 and the second opening 75, respectively function as air intakes. Further, the open end surfaces of the first opening 74 and the second opening 75 on the opening 44 side of the blower fans 41 function as air outlets.
　第１開口部７４は、壁体７３の上面（つまり、第１吸込み口１１との対向面）から右側面に繋がる第１風路を形成している。言い換えれば、第１開口部７４は、第１吸込み口１１との対向面に空気の取入口が形成され、一方の送風ファン４１の空気の吸込み口（開口部４４）側に、空気の取出口が形成された第１風路を形成している。 The first opening 74 forms a first air passage connecting the upper surface of the wall 73 (that is, the surface facing the first suction port 11) to the right surface. In other words, in the first opening 74, an air intake is formed on the opposite surface to the first suction port 11, and on the air intake port (opening 44) side of the one blower fan 41, the air outlet Form a first air passage.
　また、第２開口部７５は、壁体７３の上面から左側面に繋がる第２風路を形成している。言い換えれば、第２開口部７５は、第１吸込み口１１との対向面に空気の取入口が形成され、他方の送風ファン４１の空気の吸込み口（開口部４４）側に、空気の取出口が形成された第２風路を形成している。 Further, the second opening 75 forms a second air passage connecting the top surface of the wall 73 to the left side surface. In other words, in the second opening 75, an air intake is formed on the surface opposite to the first suction port 11, and the air intake (opening 44) side of the other blower fan 41 is the air outlet. Form a second air passage.
　これにより、第１送風ファン４１ａは、隔壁７３ａの奥側の第２開口部７５を介して第１吸い込み口１１から室内機本体部２内に取り込んだ空気を吸引することが可能となる。また、第２送風ファン４１ｂは、隔壁７３ａの手前側の第１開口部７４を介して第１吸い込み口１１から室内機本体部２内に取り込んだ空気を吸引することが可能となる。 As a result, the first blower fan 41a can suction the air taken into the indoor unit body 2 from the first suction port 11 through the second opening 75 on the back side of the partition wall 73a. Further, the second blower fan 41b can suction the air taken into the indoor unit main body 2 from the first suction port 11 through the first opening 74 on the front side of the partition wall 73a.
　送風ファン４１がファンモータ５１により回転すると、第１吸込み口１１から第１フィルタ１５を介して室内機本体部２に空気が吸い込まれる。第１吸込み口１１から室内機本体部２内に空気が吸い込まれると、モータカバー５０の外部およびファンケーシング４７の外部が正圧となり、モータカバー５０の内部およびファンケーシング４７の内部が負圧となる。 When the blower fan 41 is rotated by the fan motor 51, air is sucked into the indoor unit body 2 from the first suction port 11 via the first filter 15. When air is sucked into the indoor unit body 2 from the first suction port 11, positive pressure is applied to the outside of the motor cover 50 and the external of the fan casing 47, and negative pressure is applied to the inside of the motor cover 50 and the inside of the fan casing 47. Become.
　室内機本体部２内に吸い込まれた空気の一部は、モータカバー５０に設けられた第１開口部７４および第２開口部７５からモータカバー５０内に流入し、第１開口部７４内および第２開口部７５内を通って、駆動軸５３に平行な方向の開口部４４から、送風ファン４１に吸い込まれる。また、このとき、第１開口部７４および第２開口部７５から開口部７１ｃを通ってモータカバー５０内に流入した空気により、モータ本体５２が冷却される。ファンケーシング４７内に吸い込まれた空気は、送風ファン４１を構成する多翼ロータ４２の外周面の開口部４５から吹き出される。 A part of the air sucked into the indoor unit body 2 flows into the motor cover 50 from the first opening 74 and the second opening 75 provided in the motor cover 50, and the inside of the first opening 74 The air is drawn into the blower fan 41 from the opening 44 in the direction parallel to the drive shaft 53 through the second opening 75. At this time, the motor main body 52 is cooled by the air flowing from the first opening 74 and the second opening 75 into the motor cover 50 through the opening 71 c. The air sucked into the fan casing 47 is blown out from the opening 45 of the outer peripheral surface of the multi-blade rotor 42 constituting the blower fan 41.
　また、図７の（ｂ）および図８の（ａ）・（ｂ）に示すように、モータ収容部７１および壁体７３における、キャビネット３０の背面部３２との対向面には、背面部３２にモータカバー５０を固定する固定部材７７がそれぞれ設けられている。固定部材７７は、モータカバー５０を、キャビネット３０の背面部３２にネジ止めするための螺着部材であってもよく、爪状の掛着部材であってもよい。 Further, as shown in (b) of FIG. 7 and (a) and (b) of FIG. 8, the motor housing 71 and the wall 73 face the rear surface 32 on the surface facing the rear surface 32 of the cabinet 30. The fixing member 77 which fixes the motor cover 50 to each is provided. The fixing member 77 may be a screwing member for screwing the motor cover 50 to the back surface portion 32 of the cabinet 30, or may be a hook-like hooking member.
　なお、図７の（ｂ）および図８の（ａ）・（ｂ）では、上述したように上部モータカバー７０の背面に固定部材７７が設けられている場合を例に挙げて図示している。しかしながら、固定部材７７は、下部モータカバー６０の背面に設けられていても構わない。 7B and 8A and 8B illustrate the case where the fixing member 77 is provided on the rear surface of the upper motor cover 70 as described above. . However, the fixing member 77 may be provided on the back surface of the lower motor cover 60.
　また、図６に示すように、壁体７３の上面には、モータカバー５０を、キャビネット３０の上面部３１に固定するための固定部材７８が設けられている。下部モータカバー６０の下面（すなわち、モータ収容部７１の下面）には、モータカバー５０を、キャビネット３０の下面部３３に固定するための固定部材６７が設けられている。なお、図７の（ａ）～（ｃ）および図８の（ａ）～（ｃ）では、固定部材６７・７７・７８の図示を省略している。 Further, as shown in FIG. 6, a fixing member 78 for fixing the motor cover 50 to the upper surface portion 31 of the cabinet 30 is provided on the upper surface of the wall body 73. A fixing member 67 for fixing the motor cover 50 to the lower surface 33 of the cabinet 30 is provided on the lower surface of the lower motor cover 60 (that is, the lower surface of the motor housing 71). In FIGS. 7A to 7C and 8A to 8C, illustration of the fixing members 67, 77, and 78 is omitted.
　固定部材７８は、モータカバー５０を、キャビネット３０の上面部３１から吊り下げる吊着部材であってもよく、モータカバー５０を、キャビネット３０の上面部３１にネジ止めするための螺着部材であってもよい。また、固定部材６７は、モータカバー５０を、キャビネット３０の下面部３３にネジ止めするための螺着部材であってもよく、モータカバー５０を、キャビネット３０の下面部３３の一部に嵌合させる嵌着部材であってもよい。これら固定部材６７・７７・７８の種類および数、並びに、モータカバー５０とキャビネット３０の固定方法は、特に限定されない。 The fixing member 78 may be a hanging member for suspending the motor cover 50 from the upper surface portion 31 of the cabinet 30, and is a screwing member for screwing the motor cover 50 to the upper surface portion 31 of the cabinet 30. May be The fixing member 67 may be a screwing member for screwing the motor cover 50 to the lower surface portion 33 of the cabinet 30, and the motor cover 50 is fitted to a part of the lower surface portion 33 of the cabinet 30. It may be a fitting member. The type and number of the fixing members 67, 77, 78 and the method of fixing the motor cover 50 and the cabinet 30 are not particularly limited.
　モータカバー５０は、これら固定部材６７・７７・７８により、上部が上記上面部３１と接し、下部が上記下面部３３と接し、背面（後部）が上記背面部３２と接している。 The upper portion of the motor cover 50 is in contact with the upper surface portion 31, the lower portion is in contact with the lower surface portion 33, and the rear surface (rear portion) is in contact with the rear surface portion 32 by the fixing members 67, 77, 78.
　（効果）
　上記構成の空気調和機によれば、モータカバー５０が上記壁体７３を有していることで、ファンモータ５１の上方のスペースを、送風ファン４１の空気の吸い込みに利用することができる。このため、送風ファン４１内に吸引する空気および該送風ファン４１を介して吹出し口１７から吹き出される空気の風量を増加させることができるともに、ファンモータ５１の上部を有効活用することができる。モータカバー５０に、第１開口部７４および第２開口部７５を有する上記壁体７３が設けられていない場合、ファンモータ５１の上方が無駄なスペースになってしまう。 (effect)
According to the air conditioner of the above configuration, the space above the fan motor 51 can be used for suction of air of the blower fan 41 by the motor cover 50 having the wall body 73. Therefore, the air volume of the air sucked into the blower fan 41 and the air blown out from the outlet 17 through the blower fan 41 can be increased, and the upper portion of the fan motor 51 can be effectively used. When the wall body 73 having the first opening 74 and the second opening 75 is not provided on the motor cover 50, the space above the fan motor 51 is a wasteful space.
　また、上記構成の空気調和機によれば、第１開口部７４と第２開口部７５とが隔壁７３ａで分離されていることで、モータカバー５０の上部の第１吸込み口１１から室内機本体部２に吸い込んだ空気を、第１送風ファン４１ａおよび第２送風ファン４１ｂそれぞれに、均等かつ効率良く導くことができる。 Further, according to the air conditioner of the above configuration, the first opening 74 and the second opening 75 are separated by the partition wall 73a, so that the indoor unit main body from the first suction port 11 at the top of the motor cover 50. The air drawn into the part 2 can be uniformly and efficiently introduced to the first and second blower fans 41a and 41b.
　第１開口部７４と第２開口部７５とが隔壁７３ａで分離されていない場合、モータカバー５０の上部の第１吸込み口１１から室内機本体部２に吸い込んだ空気に対し、第１送風ファン４１ａと第２送風ファン４１ｂとの両方から吸引が行われる。 When the first opening 74 and the second opening 75 are not separated by the partition wall 73a, the air drawn into the indoor unit body 2 from the first suction port 11 at the top of the motor cover 50 is a first blower fan. Suction is performed from both 41a and the 2nd ventilation fan 41b.
　この結果、第１送風ファン４１ａに吸引される空気と第２送風ファン４１ｂに吸引される空気とが衝突し、それぞれの空気が、第１送風ファン４１ａおよび第２送風ファン４１ｂにスムーズに吸引されない。また、衝突した空気が抵抗となるため、第１開口部７４と第２開口部７５とが隔壁７３ａで分離されている場合と比較して、同じ風量を得るための電力入力値が増大する。 As a result, the air sucked by the first blower fan 41a collides with the air sucked by the second blower fan 41b, and the respective air is not smoothly sucked by the first blower fan 41a and the second blower fan 41b. . Further, since the collided air serves as a resistance, the power input value for obtaining the same air volume is increased as compared with the case where the first opening 74 and the second opening 75 are separated by the partition wall 73a.
　また、第１送風ファン４１ａに吸引される空気と第２送風ファン４１ｂに吸引される空気とが衝突することで、第１送風ファン４１ａに吸引される風量と第２送風ファン４１ｂに吸引される風量とのバランスが崩れる。このように左右の送風ファン４１に吸引される風量のバランスが崩れると、熱交換器１４のうち、一方の送風ファン４１の前面に配置された部分のみが乾き易くなる。熱交換器１４には、風が均一に当たる前提で冷媒が流れている。このため、熱交換器１４のうち、一方の送風ファン４１の前面に配置された部分のみが早く乾くと、熱交換器１４の能力が低下するとともに、乾いた部分を空気が通過することで、吹出し口１７で結露が発生するおそれがある。 Further, the air sucked by the first blower fan 41a and the air sucked by the second blower fan 41b collide with each other, so that the air amount sucked by the first blower fan 41a and the air amount sucked by the second blower fan 41b The balance with the air volume is broken. As described above, when the balance of the amount of air drawn by the left and right blower fans 41 is broken, only the portion of the heat exchanger 14 disposed on the front surface of one of the blower fans 41 tends to dry. In the heat exchanger 14, the refrigerant is flowing on the premise that the wind uniformly strikes. For this reason, when only the portion of the heat exchanger 14 disposed on the front surface of one of the blower fans 41 dries quickly, the capacity of the heat exchanger 14 decreases and air passes through the dried portion, Condensation may occur at the outlet 17.
　しかしながら、上述したように第１開口部７４と第２開口部７５とが隔壁７３ａで分離されていることで、第１送風ファン４１ａに吸引される空気と第２送風ファン４１ｂに吸引される空気とを分離することができる。このため、上記構成の空気調和機によれば、第１送風ファン４１ａおよび第２送風ファン４１ｂのそれぞれに空気がスムーズに吸引される。したがって、送風ファン４１内に吸引する空気および該送風ファン４１を介して吹出し口１７から吹き出される空気の風量を増加させることができる。 However, as described above, since the first opening 74 and the second opening 75 are separated by the partition wall 73a, the air sucked by the first blower fan 41a and the air sucked by the second blower fan 41b And can be separated. For this reason, according to the air conditioner of the above-mentioned configuration, air is sucked smoothly to each of the first blower fan 41a and the second blower fan 41b. Therefore, it is possible to increase the air volume of the air sucked into the blower fan 41 and the air blown out from the outlet 17 through the blower fan 41.
　また、上記構成の空気調和機によれば、上述したように、第１開口部７４と第２開口部７５とが隔壁７３ａで分離されていない場合と比較して、風量を基準としたときの電力入力値を低下させることができる。このため、第１開口部７４と第２開口部７５とが隔壁７３ａで分離されていない場合と比較して、低消費電力化を図ることができる。 Further, according to the air conditioner having the above configuration, as described above, the air volume is used as a reference, as compared with the case where the first opening 74 and the second opening 75 are not separated by the partition wall 73a. Power input values can be reduced. Therefore, power consumption can be reduced as compared with the case where the first opening 74 and the second opening 75 are not separated by the partition wall 73a.
　また、ファンモータ５１の位置を基準として左右の送風ファン４１の風量バランスの均一化を図ることができるので、熱交換器１４の能力の低下を押さえ、熱交換器１４の能力を十分に引き出すことができる。 In addition, since the air volume balance of the left and right blower fans 41 can be made uniform on the basis of the position of the fan motor 51, the reduction of the capacity of the heat exchanger 14 is suppressed, and the capacity of the heat exchanger 14 is sufficiently extracted. Can.
　また、モータカバー５０に上記壁体７３が設けられ、上記壁体７３に、モータカバー５０をキャビネット３０に固定する固定部材７７・７８が設けられていることで、モータカバー５０の強度を高め、かつ、モータカバー５０とキャビネット３０とを、強固に固定することができる。 The motor cover 50 is provided with the wall 73, and the wall 73 is provided with fixing members 77 and 78 for fixing the motor cover 50 to the cabinet 30, thereby enhancing the strength of the motor cover 50. And motor cover 50 and cabinet 30 can be fixed firmly.
　（変形例１）
　上述したように、本実施形態では、壁体７３に、駆動軸５３よりも前方の右側面の一部が縦方向に切り欠かれた第１開口部７４と、駆動軸５３よりも後方の左側面の一部が縦方向に切り欠かれた第２開口部７５と、が設けられている場合を例に挙げて説明した。しかしながら、壁体７３は、駆動軸５３よりも前方と、駆動軸５３よりも後方とで、左右異なる方向に開口していればよい。 (Modification 1)
As described above, in the present embodiment, in the wall body 73, the first opening 74 in which a part of the right side in front of the drive shaft 53 is cut away in the longitudinal direction, and the left side behind the drive shaft 53 The case where the 2nd opening part 75 which a part of field cut out in the lengthwise direction was provided was mentioned as an example, and was explained. However, the wall body 73 may be opened in different directions in the left and right directions in front of the drive shaft 53 and in rear of the drive shaft 53.
　このため、壁体７３には、駆動軸５３よりも前方の左側面の一部が縦方向に切り欠かれた開口部と、駆動軸５３よりも後方の右側面の一部が縦方向に切り欠かれた開口部と、が設けられていてもよい。言い換えれば、壁体７３には、奥行き方向に、平面視で、隔壁７３ａを奥側の壁部として、左側面の一部が開口された枠形状（溝形状）の開口部（切欠部）と、平面視で、隔壁７３ａを手前側の壁部として、右側面の一部が開口された枠形状（溝形状）の開口部（切欠部）とが設けられていてもよい。つまり、壁体７３は、平面視で略Ｓ字形状を有していてもよい。 Therefore, in the wall body 73, an opening in which a part of the left side surface in front of the drive shaft 53 is cut in the vertical direction, and a part of the right side surface in the rear of the drive shaft 53 is cut in the vertical direction An integral opening may be provided. In other words, the wall 73 has a frame-shaped (groove-shaped) opening (a notch) in which a part of the left side surface is opened with the partition 73a as the back wall in plan view in the depth direction A frame-shaped (groove-shaped) opening (notch) may be provided in which a part of the right side surface is opened with the partition wall 73a as a wall on the front side in plan view. That is, the wall body 73 may have a substantially S-shape in plan view.

　図９乃至図１１の（ａ）～（ｃ）に示すように、本実施形態にかかる空気調和機の室内機１は、モータカバー５０の形状を除けば、実施形態１にかかる空気調和機の室内機１と同じ構成を有している。本実施形態にかかるモータカバー５０は、実施形態１にかかる下部モータカバー６０と上部モータカバー７０とが、固定部材７７・７８・６７の形状を除いて、上下反転した形状を有している。本実施形態では、上部モータカバー７０に壁体７３が設けられておらず、その代わりに、下部モータカバー６０に壁体６３が設けられている。すなわち、本実施形態にかかる上部モータカバー７０は、モータ収容部７１と、連結部７２と、固定部材７７・７８と、を備えている。本実施形態にかかる下部モータカバー６０は、モータ収容部６１と、連結部６２と、壁体６３と、図示しない固定部材と、を備えている。なお、図１０の（ａ）・（ｂ）および図１１の（ａ）～（ｃ）では、固定部材７７・７８および下部モータカバー６０側の固定部材の図示を省略している。 As shown in (a) to (c) of FIGS. 9 to 11, the indoor unit 1 of the air conditioner according to the present embodiment is the same as the air conditioner according to the first embodiment except for the shape of the motor cover 50. It has the same configuration as the indoor unit 1. The motor cover 50 according to the present embodiment has a shape in which the lower motor cover 60 and the upper motor cover 70 according to the first embodiment are upside down except for the shapes of the fixing members 77, 78, and 67. In the present embodiment, the wall body 73 is not provided on the upper motor cover 70, and instead, the wall body 63 is provided on the lower motor cover 60. That is, the upper motor cover 70 according to the present embodiment includes the motor housing portion 71, the connecting portion 72, and the fixing members 77 and 78. The lower motor cover 60 according to the present embodiment includes a motor housing portion 61, a connection portion 62, a wall 63, and a fixing member (not shown). In (a) and (b) of FIG. 10 and (a) to (c) of FIG. 11, the fixing members 77 and 78 and the fixing member on the lower motor cover 60 side are not shown.
　本実施形態にかかるモータ収容部７１は、実施形態１にかかるモータ収容部６１と同じ形状を有している。本実施形態にかかるモータ収容部６１は、実施形態１にかかるモータ収容部７１と同じ形状を有している。 The motor housing 71 according to the present embodiment has the same shape as the motor housing 61 according to the first embodiment. The motor housing 61 according to the present embodiment has the same shape as the motor housing 71 according to the first embodiment.
　なお、モータ収容部６１・７１の構成は、実施形態１にかかるモータ収容部６１・７１の構成と同じである。モータ収容部６１の下面の中央部には、図１１の（ａ）～（ｃ）に示すように、駆動軸５３に直交する方向に沿って、帯状に開口部６１ｃが設けられている。このため、モータ本体５２の下面の一部は、開口部６１ｃから露出している。また、図示はしないが、モータ収容部６１の上面の中央部には、駆動軸５３に直交する方向に沿って、帯状の開口部７１ｃ（図８の（ａ）～（ｃ）参照）が設けられている。モータ本体５２の上面の一部は、開口部７１ｃから露出している。 The configuration of the motor housings 61 and 71 is the same as the configuration of the motor housings 61 and 71 according to the first embodiment. At the central portion of the lower surface of the motor housing portion 61, as shown in (a) to (c) of FIG. 11, an opening 61c is provided in a strip shape along the direction orthogonal to the drive shaft 53. Therefore, part of the lower surface of the motor main body 52 is exposed from the opening 61 c. Although not shown, a belt-like opening 71 c (see (a) to (c) in FIG. 8) is provided at the center of the upper surface of the motor housing 61 along the direction orthogonal to the drive shaft 53. It is done. A part of the upper surface of the motor main body 52 is exposed from the opening 71 c.
　本実施形態にかかる連結部７２は、実施形態１にかかる連結部６２と同じ形状を有している。本実施形態にかかる連結部６２は、実施形態１にかかる連結部７２と同じ形状を有している。 The connecting portion 72 according to the present embodiment has the same shape as the connecting portion 62 according to the first embodiment. The connecting portion 62 according to the present embodiment has the same shape as the connecting portion 72 according to the first embodiment.
　したがって、例えば、上部モータカバー７０は、連結部７２として、例えば、モータ収容部７１から水平に突出し、図示しないネジ穴を有するフリンジ部を有している。下部モータカバー６０は、連結部６２として、例えばネジ山に結合するネジ溝が設けられた筒状部６２ａを有し、モータ収容部６１から水平に突出するフリンジ部を有している。但し、本実施形態はこれに限定されるものではなく、連結部６２・７２は、実施形態１と同じ形状を有していても構わない。 Therefore, for example, the upper motor cover 70 has, as the connecting portion 72, for example, a fringe portion that protrudes horizontally from the motor housing portion 71 and has a screw hole (not shown). The lower motor cover 60 has, as the connecting portion 62, for example, a cylindrical portion 62a provided with a screw groove coupled to a screw thread, and has a fringe portion projecting horizontally from the motor housing portion 61. However, the present embodiment is not limited to this, and the connecting portions 62 and 72 may have the same shape as the first embodiment.
　壁体６３は、実施形態１にかかる壁体７３と同じ形状を有している。壁体６３は、モータ収容部６１の下面に、駆動軸５３に直交する方向に沿って、第２吸込み口１２に向かって下方に突出して設けられている。 The wall 63 has the same shape as the wall 73 according to the first embodiment. The wall body 63 is provided on the lower surface of the motor housing portion 61 so as to project downward toward the second suction port 12 in a direction perpendicular to the drive shaft 53.
　壁体６３は、第２吸込口１２からキャビネット３０内に吸い込んだ空気の流れを、隣り合う送風ファン４１の一方に向う流れと他方に向う流れとに分離してそれぞれの送風ファン４１に導く分離壁兼導風壁として機能する。また、壁体６３は、モータカバー５０とキャビネット３０とを固定する固定部材として機能する。 The wall body 63 separates the flow of air sucked into the cabinet 30 from the second suction port 12 into a flow toward one of the adjacent blower fans 41 and a flow toward the other and separates the flows into the respective blower fans 41 It acts as a wall and a guiding wall. In addition, the wall body 63 functions as a fixing member for fixing the motor cover 50 and the cabinet 30.
　壁体６３には、モータカバー５０を正面から見たときの奥行き方向に、該奥行き方向の中央部を境にして手前側の右側面の一部が縦方向に切り欠かれた第１開口部６４と、奥側の左側面の一部が縦方向に切り欠かれた第２開口部６５と、が設けられている。 In the wall 63, a first opening in which a part of the right side on the near side is cut in the vertical direction with the center in the depth direction in the depth direction when the motor cover 50 is viewed from the front 64 and a second opening 65 in which a part of the left side surface on the back side is cut away in the vertical direction.
　第１開口部６４と第２開口部６５とは、隔壁６３ａで分離されている。隔壁６３ａは、平面視で駆動軸５３と一直線上に位置するように、駆動軸５３に沿って開口部６１ｃを跨いでいる。このため、第１開口部６４は、隔壁６３ａを挟んで、第２開口部６５よりも、室内機１の前面側に位置している。第２開口部６５は、隔壁６３ａを挟んで、第１開口部６４よりも、室内機１の背面側に位置している。 The first opening 64 and the second opening 65 are separated by the partition wall 63a. The partition wall 63a straddles the opening 61c along the drive shaft 53 so as to be positioned on a straight line with the drive shaft 53 in a plan view. Therefore, the first opening 64 is located on the front side of the indoor unit 1 with respect to the second opening 65, with the partition wall 63a interposed therebetween. The second opening 65 is located on the back side of the indoor unit 1 with respect to the first opening 64 with the partition wall 63 a interposed therebetween.
　第１開口部６４は、平面視で、隔壁６３ａを奥側の壁部として、右側面の一部が開口された枠形状（言い換えれば、溝形状）を有している。第２開口部６５は、平面視で、隔壁６３ａを手前側の壁部として、左側面の一部が開口された枠形状（言い換えれば、溝形状）を有している。このため、壁体６３は、平面視で略逆Ｓ字形状を有している。 The first opening 64 has a frame shape (in other words, a groove shape) in which a part of the right side surface is opened with the partition wall 63a as a wall portion on the back side in plan view. The second opening 65 has a frame shape (in other words, a groove shape) in which a part of the left side surface is opened with the partition wall 63a as a wall on the front side in plan view. For this reason, the wall body 63 has a substantially reverse S-shape in plan view.
　図９に示すように、第１開口部６４は、駆動軸５３の軸方向において、駆動軸５３の右側に配置された第２送風ファン４１ｂの一方の開口部４４側が開放されている。第２開口部６５は、駆動軸５３の軸方向において、駆動軸５３の左側に配置された第１送風ファン４１ａの一方の開口部４４側が開放されている。なお、第１開口部６４および第２開口部６５は、駆動軸５３の軸方向において、隣り合う送風ファン４１の開口部４４に面していることが、より望ましい。 As shown in FIG. 9, in the first opening 64, one opening 44 side of the second blower fan 41 b disposed on the right side of the drive shaft 53 is opened in the axial direction of the drive shaft 53. In the second opening 65, one opening 44 side of the first blower fan 41a disposed on the left side of the drive shaft 53 is opened in the axial direction of the drive shaft 53. More preferably, the first opening 64 and the second opening 65 face the opening 44 of the adjacent blower fan 41 in the axial direction of the drive shaft 53.
　また、第１開口部６４および第２開口部６５は、縦方向において、室内機本体部２の第２吸込み口１２に面して設けられている。つまり、第１開口部６４および第２開口部６５の下面（つまり、下側の開口端面）は、それぞれ、室内機本体部２の第２吸込み口１２に面して設けられている。 The first opening 64 and the second opening 65 are provided to face the second suction port 12 of the indoor unit body 2 in the vertical direction. That is, the lower surfaces (that is, lower open end surfaces) of the first opening 64 and the second opening 65 are provided so as to face the second suction port 12 of the indoor unit body 2 respectively.
　第１開口部６４および第２開口部６５の下面である、第２吸込み口１２側の開口端面は、それぞれ、空気の取込み口として機能する。また、第１開口部６４および第２開口部６５における、各送風ファン４１の開口部４４側の開口端面は、空気の取出口として機能する。 The open end surfaces on the second suction port 12 side, which are the lower surfaces of the first opening 64 and the second opening 65, respectively function as air intake ports. Further, the open end surfaces of the first opening 64 and the second opening 65 on the opening 44 side of the blower fans 41 function as air outlets.
　第１開口部６４は、壁体６３の下面（つまり、第２吸込み口１２との対向面）から右側面に繋がる第１風路を形成している。言い換えれば、第１開口部６４は、第２吸込み口１２との対向面に空気の取入口が形成され、一方の送風ファン４１の空気の吸込み口（開口部４４）側に、空気の取出口が形成された第１風路を形成している。 The first opening 64 forms a first air passage connecting the lower surface of the wall 63 (that is, the surface facing the second suction port 12) to the right side. In other words, in the first opening 64, an air intake is formed on the opposite surface to the second suction opening 12, and the air extraction opening on the air intake (opening 44) side of the one blower fan 41 Form a first air passage.
　また、第２開口部６５は、壁体６３の下面から左側面に繋がる第２風路を形成している。言い換えれば、第２開口部６５は、第２吸込み口１２との対向面に空気の取入口が形成され、他方の送風ファン４１の空気の吸込み口（開口部４４）側に、空気の取出口が形成された第２風路を形成している。 In addition, the second opening 65 forms a second air passage connecting the lower surface of the wall body 63 to the left side surface. In other words, in the second opening 65, an air intake is formed on the opposite surface to the second suction port 12, and the air outlet is formed on the air intake (opening 44) side of the other blower fan 41. Form a second air passage.
　これにより、第１送風ファン４１ａは、隔壁６３ａの奥側の第２開口部６５を介して第２吸い込み口１２から室内機本体部２内に取り込んだ空気を吸引することが可能となる。また、第２送風ファン４１ｂは、隔壁６３ａの手前側の第１開口部６４を介して第２吸い込み口１２から室内機本体部２内に取り込んだ空気を吸引することが可能となる。 As a result, the first blower fan 41a can suction the air taken into the indoor unit body 2 from the second suction port 12 through the second opening 65 on the back side of the partition wall 63a. Further, the second blower fan 41b can suction the air taken into the indoor unit main body 2 from the second suction port 12 through the first opening 64 on the front side of the partition wall 63a.
　送風ファン４１がファンモータ５１により回転すると、第２吸込み口１２から第２フィルタ１６を介して室内機本体部２に空気が吸い込まれる。第２吸込み口１２から室内機本体部２内に空気が吸い込まれると、モータカバー５０の外部およびファンケーシング４７の外部が正圧となり、モータカバー５０の内部およびファンケーシング４７の内部が負圧となる。 When the blower fan 41 is rotated by the fan motor 51, air is sucked into the indoor unit body 2 from the second suction port 12 via the second filter 16. When air is sucked into the indoor unit body 2 from the second suction port 12, positive pressure is applied to the outside of the motor cover 50 and the external of the fan casing 47, and negative pressure is applied to the inside of the motor cover 50 and the inside of the fan casing 47. Become.
　室内機本体部２内に吸い込まれた空気の一部は、モータカバー５０に設けられた第１開口部６４および第２開口部６５からモータカバー５０内に流入し、第１開口部６４内および第２開口部６５内を通って、駆動軸５３に平行な方向の開口部４４から、送風ファン４１に吸い込まれる。また、このとき、第１開口部６４および第２開口部６５から開口部６１ｃを通ってモータカバー５０内に流入した空気により、モータ本体５２が冷却される。ファンケーシング４７内に吸い込まれた空気は、送風ファン４１を構成する多翼ロータ４２の外周面の開口部４５から吹き出される。 A part of the air sucked into the indoor unit body 2 flows into the motor cover 50 from the first opening 64 and the second opening 65 provided in the motor cover 50, and the inside of the first opening 64 The air is drawn into the blower fan 41 from the opening 44 in the direction parallel to the drive shaft 53 through the second opening 65. At this time, the motor main body 52 is cooled by the air flowing from the first opening 64 and the second opening 65 into the motor cover 50 through the opening 61 c. The air sucked into the fan casing 47 is blown out from the opening 45 of the outer peripheral surface of the multi-blade rotor 42 constituting the blower fan 41.
　なお、下部モータカバー６０の背面および下面並びに上部モータカバー７０の背面および上面には、それぞれ、モータカバー５０を、キャビネット３０に固定するための固定部材が設けられている。これら固定部材としては、例えば、固定部材６７・７７・７８と同様の固定部材を用いることができる。なお、本実施形態でも、これら固定部材の種類および数、並びに、モータカバー５０とキャビネット３０の固定方法は、特に限定されない。 Fixing members for fixing the motor cover 50 to the cabinet 30 are provided on the back and lower surfaces of the lower motor cover 60 and the back and upper surfaces of the upper motor cover 70, respectively. As these fixing members, for example, fixing members similar to the fixing members 67, 77, 78 can be used. Also in this embodiment, the types and the number of the fixing members, and the fixing method of the motor cover 50 and the cabinet 30 are not particularly limited.
　（効果）
　上記構成の室内機１によれば、モータカバー５０に、実施形態１にかかる壁体７３に代えて上記壁体６３が設けられていることで、ファンモータ５１の上方のスペースに代えて、ファンモータ５１の下方のスペースを、送風ファン４１の空気の吸い込みに利用することができる。本実施形態によれば、この点を除けば、実施形態１と同じ効果を得ることができる。 (effect)
