 従来の空気調和機の室内機には、空調対象空間の天井に埋め込まれて、あるいは空調対象空間の天井に吊り下げられて設置されるものが存在する。このように設置される従来の室内機としては、例えば、筐体の下面部の略中央部に開口した吸込口と、下面部において該吸込口の四方を囲むように開口した4つの吹出口とを備え、熱交換器で熱交換後の空気を四方に吹き出すことが出来る室内機が知られている。さらに、このように設置される従来の室内機には、4つの吹出口のそれぞれに対応して、吹出口から吹き出される空気の横方向の角度を調節する左右風向調節部を備えたものも提案されている(例えば、特許文献1参照)。 Among the indoor units of the conventional air conditioner, there are units that are embedded in the ceiling of the air conditioning target space or suspended and installed on the ceiling of the air conditioning target space. As a conventional indoor unit installed in this way, for example, a suction port opened at a substantially central portion of the lower surface of the housing, and four blowout ports opened so as to surround four sides of the suction port at the lower surface. There is known an indoor unit capable of blowing out air after heat exchange with a heat exchanger in all directions. Furthermore, the conventional indoor units installed in this way also have left and right wind direction adjustment units that adjust the lateral angle of the air blown out from the air outlet corresponding to each of the 4 air outlets. It is proposed (for example, refer patent document 1).

The left and right wind direction adjusting unit is provided with a plurality of left and right wind direction adjusting plates disposed at predetermined intervals in the lateral direction in the blowout flow path, and a drive motor for swinging the plurality of left and right wind direction adjusting plates. ing. By swinging the plurality of left and right wind direction adjusting plates and changing the inclination angle of the plurality of left and right wind direction adjusting plates, it is possible to adjust the lateral angle of the air blown out from the air outlet.

 従来の空気調和機の室内機においては、左右風向調節部の駆動モーターは、吹出流路と連通する箇所に配置されていた。すなわち、従来の空気調和機の室内機においては、左右風向調節部の駆動モーターは、熱交換器と熱交換後の空気と接する環境下に配置されていた。このため、例えば冷房運転時には、熱交換器で冷却された空気と発熱した駆動モーターとの温度差によって、駆動モーターに結露が生じる。また、例えば暖房運転時には、熱交換器で加熱された空気により、駆動モーターが加熱される。これにより、駆動モーターの温度が上昇してしまう。このように、従来の空気調和機の室内機は、熱交換器と熱交換後の空気の温度の影響を左右風向調節部の駆動モーターが受けることにより、駆動モーターの耐久性が悪化してしまうという課題があった。 In the conventional indoor unit of the air conditioner, the drive motor of the left and right air direction adjusting unit is disposed at a location in communication with the blowout passage. That is, in the indoor unit of the conventional air conditioner, the drive motor of the left and right wind direction adjusting unit is disposed in an environment in contact with the heat exchanger and the air after heat exchange. For this reason, for example, during the cooling operation, dew condensation occurs on the drive motor due to the temperature difference between the air cooled by the heat exchanger and the heat generated drive motor. Also, for example, in the heating operation, the drive motor is heated by the air heated by the heat exchanger. This causes the temperature of the drive motor to rise. As described above, in the conventional air conditioner indoor unit, the durability of the drive motor is deteriorated because the drive motor of the left and right wind direction adjustment units is affected by the temperature of the air after heat exchange with the heat exchanger. There was a problem called.

Embodiment 1
FIG. 1 is a perspective view of the entire indoor unit of the air conditioner according to Embodiment 1 of the present invention as viewed obliquely from below. Moreover, FIG. 2 is a longitudinal cross-sectional view of the whole indoor unit of the air conditioner concerning Embodiment 1 of this invention.
The indoor unit 100 of the air conditioner according to the first embodiment is embedded in the ceiling of a space to be air-conditioned such as a room or suspended on the ceiling of the space to be air-conditioned. This indoor unit 100 is provided with the housing | casing 1 which the suction inlet 2 and the blower outlet 3 opened in the lower surface part. In the first embodiment, an example in which four air outlets 3 are formed is shown. The housing 1 is, for example, a substantially rectangular parallelepiped box whose inside is hollow. The suction port 2 is opened at, for example, a substantially central portion of the lower surface portion of the housing 1. The four outlets 3 are open so as to surround four sides of the inlet 2. The outlets 3 have, for example, a rectangular shape, and the long sides are arranged along the respective sides of the lower surface portion of the housing 1. In addition, a suction grill 2 a and a filter 9 are provided in the suction port 2.
 また、筐体1の内部には、吸込口2と対向する位置に、例えばターボファン等の遠心ファンである送風機6が設けられている。例えば、送風機6の中心軸は、平面視において吸込口2の中心と略同位置に配置されている。送風機6は、空調対象空間の空気を吸込口2から筐体1内に吸い込み、吹出口3から吹き出すものである。また、筐体1の内部には、送風機6を囲むように、例えばフィンアンドチューブ型の熱交換器7が設けられている。熱交換器7は、該熱交換器7の内部に流れる冷媒と、送風機6によって筐体1内に吸い込まれた空調対象空間の空気と、を熱交換させるものである。 Further, inside the housing 1, a blower 6 which is a centrifugal fan such as a turbo fan is provided at a position facing the suction port 2. For example, the central axis of the blower 6 is disposed at substantially the same position as the center of the suction port 2 in plan view. The blower 6 sucks the air in the space to be air-conditioned from the suction port 2 into the housing 1 and blows it out from the blow-out port 3. Further, a fin and tube type heat exchanger 7 is provided inside the housing 1 so as to surround the blower 6, for example. The heat exchanger 7 exchanges heat between the refrigerant flowing inside the heat exchanger 7 and the air in the air-conditioned space sucked into the housing 1 by the blower 6.
 この熱交換器7は、平面視において、吸込口2の外周側であり、吹出口3の内周側となる位置に配置されている。すなわち筐体1には、吸込口2と熱交換器7とを連通させる吸込流路4と、熱交換器7と吹出口3とを連通させる吹出流路5とが形成されている。このため、図2に吸込空気101及び吹出空気102として矢印で示すように、送風機6が回転することによって、空調対象空間の空気は、吸込口2から筐体1内に吸い込まれ、吸込流路4を通って熱交換器7に流入する構成となっている。また、熱交換器7に流入した空調対象空間の空気は、熱交換器7を通る際に該熱交換器7の冷媒流路内を流れる冷媒と熱交換して空調空気となり、吹出流路5を通って吹出口3から空調対象空間へ吹き出される構成となっている。 The heat exchanger 7 is disposed on the outer peripheral side of the suction port 2 and on the inner peripheral side of the blowout port 3 in plan view. That is, in the housing 1, a suction flow passage 4 communicating the suction port 2 and the heat exchanger 7 and a blowout flow passage 5 communicating the heat exchanger 7 and the blowout port 3 are formed. Therefore, as shown by the arrows in FIG. 2 as the suction air 101 and the blowout air 102, the air in the space to be air-conditioned is sucked into the housing 1 from the suction port 2 by the rotation of the blower 6. It is configured to flow into the heat exchanger 7 through 4. In addition, the air in the air-conditioned space that has flowed into the heat exchanger 7 exchanges heat with the refrigerant flowing in the refrigerant flow path of the heat exchanger 7 when passing through the heat exchanger 7 and becomes air conditioned air. It blows out from the blower outlet 3 to the air-conditioning object space through the.
 なお、本実施の形態1では4つの吹出口3が形成されているため、吹出流路5も4つ形成されることとなる。また、吹出流路5の断面形状は、吹出口3と同様に、例えば長方形状をしており、長辺が筐体1の下面部の各辺に沿う形状となっている。また、本実施の形態1に係る室内機100は、吸込口2と送風機6との間に、吸込口2から吸込流路4内に吸い込まれた空調対象空間の空気を送風機6へ導くベルマウス8も備えている。 In addition, in this Embodiment 1, since four blower outlets 3 are formed, four blow-off flow paths 5 will be formed. Further, the cross-sectional shape of the blowout passage 5 is, for example, rectangular as in the case of the blowout port 3, and the long side is a shape along each side of the lower surface portion of the housing 1. In addition, the indoor unit 100 according to the first embodiment is a bell mouth that guides the air in the air conditioning target space sucked from the suction port 2 into the suction flow path 4 between the suction port 2 and the fan 6 to the fan 6. It also has eight.
 また、本実施の形態1に係る室内機100は、吹出流路5に、吹出口3から吹き出される空調空気の角度を調節する上下風向調節板51及び複数の左右風向調節板41が揺動自在に設けられている。 Further, in the indoor unit 100 according to the first embodiment, the up and down wind direction adjusting plates 51 and the plurality of left and right air direction adjusting plates 41 that adjust the angle of the conditioned air blown out from the blowout port 3 to the blowout flow path 5 swing. It is freely provided.
 上下風向調節板51は、吹出口3から吹き出される空調空気の上下方向の角度を調節するものである。この上下風向調節板51は、吹出流路5の長手方向に延びる板状部材である。また、上下風向調節板51は、吹出流路5の長手方向に延びる回転軸を中心として、上下方向に揺動する構成となっている。上下風向調節板51の上下方向の揺動は、駆動モーター等である駆動装置52で行われる。このため、上下風向調節板51の外周側端部の位置が上方へ行くほど、吹出口3から吹き出される空調空気は、水平方向に近い角度で吹き出されることとなる。また、上下風向調節板51の外周側端部の位置が下方へ行くほど、吹出口3から吹き出される空調空気は、下方向に吹き出されることとなる。 The up and down wind direction adjusting plate 51 is used to adjust the angle in the up and down direction of the conditioned air blown out from the air outlet 3. The up and down wind direction adjusting plate 51 is a plate-like member extending in the longitudinal direction of the blowout passage 5. Further, the up and down wind direction adjusting plate 51 is configured to swing up and down around a rotation axis extending in the longitudinal direction of the outlet flow passage 5. The swinging of the vertical wind direction adjusting plate 51 in the vertical direction is performed by a drive device 52 which is a drive motor or the like. For this reason, the conditioned air blown out from the outlet 3 is blown out at an angle close to the horizontal direction as the position of the outer peripheral end of the up and down wind direction adjusting plate 51 goes upward. Further, as the position of the outer peripheral side end of the vertical air flow direction adjustment plate 51 goes downward, the conditioned air blown out from the blowout port 3 is blown out downward.
 複数の左右風向調節板41は、後述する左右風向調節部40の構成部品である。左右風向調節部40は、吹出口3から吹き出される空調空気の横方向の角度を調節するものである。左右風向調節部40は、吹出口3毎に設けられている。複数の左右風向調節板41は、吹出流路5内において、吹出流路5の長手方向(横方向)に、規定の間隔を空けて配置されている。左右風向調節板41のそれぞれは、揺動自在に吹出流路5内に配置されている。例えば、左右風向調節板41のそれぞれは、下端部が左右方向に揺動する。そして、左右風向調節板41の下端部が移動した方向に、吹出口3から吹き出される空調空気は曲がって吹き出されることとなる。左右風向調節板41の揺動は、左右風向調節部40の後述する駆動モーター45の動力によって行われる。なお、左右風向調節部40の詳細は後述する。 The plurality of left and right wind direction adjusting plates 41 are components of a left and right wind direction adjusting unit 40 described later. The left and right wind direction adjusting unit 40 adjusts the lateral angle of the conditioned air blown out from the outlet 3. The left and right wind direction adjusting unit 40 is provided for each of the outlets 3. The plurality of left and right wind direction adjusting plates 41 are disposed at predetermined intervals in the longitudinal direction (lateral direction) of the blowout passage 5 in the blowout passage 5. Each of the left and right wind direction adjusting plates 41 is swingably disposed in the blowout flow path 5. For example, the lower end portion of each of the left and right wind direction adjusting plates 41 swings in the left and right direction. Then, the conditioned air blown out from the outlet 3 is bent and blown out in the direction in which the lower end portion of the left and right wind direction adjusting plate 41 has moved. The swinging of the left and right wind direction adjusting plate 41 is performed by the power of a drive motor 45 described later of the left and right wind direction adjusting unit 40. The details of the left and right wind direction adjustment unit 40 will be described later.

 空調対象空間の天井に埋め込まれて、あるいは空調対象空間の天井に吊り下げられて設置される空気調和機の室内機には、コスト削減等の観点から、左右風向調節部40を設けていないものが要求される場合がある。このような場合、左右風向調節部を備えた室内機においては、該左右風向調節部を室内機から取り外すこととなる。これにより、左右風向調節部の要不要にかかわらず、筐体を兼用出来るからである。このため、本実施の形態1に係る室内機100においても、左右風向調節部40が不要な場合、該左右風向調節部40を室内機100から取り外すこととなる。 From the viewpoint of cost reduction, etc., the indoor unit of the air conditioner installed in the ceiling of the space to be air conditioned or suspended from the ceiling of the space to be air conditioned is not provided with the left and right wind direction adjustment unit 40 May be required. In such a case, in the indoor unit provided with the left and right wind direction adjusting unit, the left and right wind direction adjusting unit is removed from the indoor unit. Thereby, the housing can be used regardless of the necessity of the left and right wind direction adjusting unit. Therefore, also in the indoor unit 100 according to the first embodiment, the left and right wind direction adjusting unit 40 is removed from the indoor unit 100 when the left and right air direction adjusting unit 40 is unnecessary.
 ここで、室内機本体10と左右風向ケースメント20とを一体形成していた場合、すなわち、室内機本体10の下部を延ばして、該延ばした箇所を左右風向ケースメント20としていた場合、左右風向調節部40は、室内機本体10に設けられることとなる。このような場合、左右風向調節部40を室内機100から取り外すと、室内機本体10には、左右風向調節部40が設置されていた空間が存在することとなる。したがって、左右風向調節部40が不要な場合、左右風向ケースメント20が一体形成された室内機本体10は、必要以上に大型化してしまう。すなわち、室内機本体10と左右風向ケースメント20とが一体形成されていた場合、左右風向調節部40が不要な際には、室内機100が必要以上に大型化してしまう。 Here, when the indoor unit body 10 and the left and right wind direction casement 20 are integrally formed, that is, when the lower part of the indoor unit main body 10 is extended and the extended portion is the left and right wind direction casement 20, the left and right wind direction The adjustment unit 40 is provided to the indoor unit main body 10. In such a case, when the left and right wind direction adjusting unit 40 is removed from the indoor unit 100, a space in which the left and right wind direction adjusting unit 40 is installed exists in the indoor unit main body 10. Therefore, when the left and right wind direction adjustment unit 40 is unnecessary, the indoor unit body 10 integrally formed with the left and right wind direction casement 20 becomes larger than necessary. That is, when the indoor unit main body 10 and the left and right wind direction casement 20 are integrally formed, the indoor unit 100 becomes larger than necessary when the left and right wind direction adjustment unit 40 is unnecessary.
 しかしながら、本実施の形態1に係る室内機100においては、上述のように、室内機本体10と左右風向ケースメント20とを別体で構成し、左右風向調節部40を左右風向ケースメント20に設けている。このため、本実施の形態1に係る室内機100においては、左右風向調節部40が不要な際、左右風向ケースメント20を取り外し、化粧パネル30を室内機本体10の下部に取り付ければよい。これにより、左右風向調節部40が不要な際に、室内機100が必要以上に大型化してしまうことを防止出来る。 However, in the indoor unit 100 according to the first embodiment, as described above, the indoor unit main body 10 and the left and right wind direction casement 20 are configured separately, and the left and right wind direction adjustment unit 40 is formed on the left and right wind direction casement 20. It is provided. For this reason, in the indoor unit 100 according to the first embodiment, when the left and right wind direction adjusting unit 40 is unnecessary, the left and right wind direction casement 20 may be removed and the decorative panel 30 may be attached to the lower part of the indoor unit main body 10. Thereby, when the left and right wind direction adjusting unit 40 is unnecessary, it is possible to prevent the indoor unit 100 from being larger than necessary.
 続いて、左右風向調節部40の詳細について説明する。 Subsequently, details of the left and right wind direction adjustment unit 40 will be described.

Note that FIG. 4 shows a state in which two of the left and right wind direction adjusting parts 40 among the four left and right wind direction adjusting parts 40 provided in the left and right wind direction casement 20 are not attached. Moreover, in FIG. 5, the drive device 44 of the left and right wind direction adjustment part 40 is shown in the state which is not a cross section.
 左右風向調節部40は、上述した複数の左右風向調節板41と、支持台42と、連結部材43と、駆動装置44とを備えている。複数の左右風向調節板41は、支持台42の側面部に揺動自在に支持されている。この支持台42は、第2吹出流路25の長手方向に沿うように、左右風向ケースメント20に取り付けられる。支持台42を左右風向ケースメント20に取り付けることにより、複数の左右風向調節板41は、第2吹出流路25内に配置されることとなる。この際、複数の左右風向調節板41は、第2吹出流路25内において、支持台42よりも左右風向ケースメント20の外周面側に配置される。換言すると、第2吹出流路25内において、支持台42は、複数の左右風向調節板41よりも左右風向ケースメント20の内周側に、つまり複数の左右風向調節板41よりも第2吸込流路24側に配置される。 The left and right wind direction adjusting unit 40 includes the plurality of left and right wind direction adjusting plates 41 described above, a support 42, a connecting member 43, and a drive device 44. The plurality of left and right wind direction adjusting plates 41 are swingably supported by side surfaces of the support base 42. The support 42 is attached to the left and right wind direction casement 20 along the longitudinal direction of the second blowoff channel 25. By attaching the support base 42 to the left and right wind direction casement 20, the plurality of left and right wind direction adjusting plates 41 are disposed in the second blowout flow path 25. At this time, the plurality of left and right wind direction adjusting plates 41 are disposed on the outer peripheral surface side of the left and right wind direction casement 20 with respect to the support base 42 in the second blowoff flow path 25. In other words, in the second outlet flow passage 25, the support 42 is closer to the inner peripheral side of the left and right wind direction casement 20 than the plurality of left and right wind direction adjustment plates 41, that is, the second suction rather than the plurality of left and right wind direction adjustment plates 41. It is arrange | positioned at the flow path 24 side.
 また、左右風向調節板41のそれぞれは、連結部材43によって連結されている。連結部材43は、駆動装置44とも接続されている。本実施の形態1に係る連結部材43は、左右風向調節板41のそれぞれを連結する第1連結部材43aと、該第1連結部材43aと駆動装置44とを連結する第2連結部材43bとで、構成されている。 Further, each of the left and right wind direction adjusting plates 41 is connected by a connecting member 43. The connection member 43 is also connected to the drive device 44. The connecting member 43 according to the first embodiment includes a first connecting member 43 a connecting the left and right wind direction adjusting plates 41 and a second connecting member 43 b connecting the first connecting member 43 a and the drive device 44. ,It is configured.
 駆動装置44は、駆動モーター45と、該駆動モーター45と第2連結部材43bとを接続する動力伝達機構46とを備えている。動力伝達機構46は、歯車等で構成され、駆動モーター45の動力を第2連結部材43bに伝達するものである。すなわち、駆動モーター45が回転することにより、この回転動力は、動力伝達機構46及び連結部材43を介して複数の左右風向調節板41に伝えられる。詳しくは、駆動モーター45がある回転方向に回転した際、各左右風向調節板41の下端部は、ある一方向に移動する。また、駆動モーター45が前記回転方向とは逆方向に回転した際、各左右風向調節板41の下端部は、前記一方向とは反対方向へ移動する。このように構成された駆動装置44は、支持台42に取り付けられる。 The drive device 44 includes a drive motor 45 and a power transmission mechanism 46 connecting the drive motor 45 and the second connecting member 43 b. The power transmission mechanism 46 is configured by a gear or the like, and transmits the power of the drive motor 45 to the second connection member 43 b. That is, when the drive motor 45 rotates, this rotational power is transmitted to the plurality of left and right wind direction adjusting plates 41 via the power transmission mechanism 46 and the connection member 43. Specifically, when the drive motor 45 is rotated in a certain rotational direction, the lower end portion of each of the left and right wind direction adjusting plates 41 moves in one direction. Further, when the drive motor 45 rotates in the direction opposite to the rotation direction, the lower end portions of the left and right wind direction adjusting plates 41 move in the direction opposite to the one direction. The drive device 44 configured in this manner is attached to the support base 42.
 また、駆動装置44が支持台42に取り付けられた状態では、平面視において、駆動モーター45は、動力伝達機構46よりも左右風向ケースメント20の内周側に突出している。換言すると、支持台42における左右風向調節板41を支持している箇所を基準としてみた場合、駆動モーター45は、当該箇所よりも左右風向ケースメント20の内周側に突出している。また、駆動装置44の下部には、蓋47が設けられている。 Further, in a state in which the drive device 44 is attached to the support base 42, the drive motor 45 protrudes to the inner peripheral side of the left and right wind direction casement 20 with respect to the power transmission mechanism 46 in plan view. In other words, when viewed from the point of supporting the left and right wind direction adjusting plate 41 in the support base 42, the drive motor 45 protrudes to the inner peripheral side of the left and right wind direction casement 20 than the point. Further, a lid 47 is provided below the drive device 44.
 左右風向ケースメント20は、各第2吹出流路25の側方に、収納室21を有している。換言すると、収納室21は、下方から左右風向ケースメント20を観察した状態において、左右風向ケースメント20の角部に配置されている。さらに換言すると、収納室21は、筐体1を下面部側から観察した状態において、筐体1の角部に配置されている。収納室21は、左右風向ケースメント20に左右風向調節部40を取り付けた際、駆動装置44を収納する室である。収納室21は、下部が開口した凹部である。また、収納室21に駆動装置44が収納されていない状態においては、収納室21は、第2吹出流路25の側端部と連通している。 The left and right wind direction casement 20 has a storage room 21 on the side of each of the second blowout flow paths 25. In other words, the storage room 21 is disposed at the corner of the left and right wind direction casement 20 in a state where the left and right wind direction casement 20 is observed from below. Furthermore, in other words, the storage room 21 is disposed at the corner of the housing 1 in a state where the housing 1 is observed from the lower surface side. The storage room 21 is a room for storing the drive device 44 when the left and right wind direction adjustment unit 40 is attached to the left and right wind direction casement 20. The storage chamber 21 is a recess whose lower portion is open. Further, in a state in which the drive device 44 is not stored in the storage room 21, the storage room 21 communicates with the side end of the second blowout flow path 25.
 一方、収納室21に駆動装置44が収納された状態においては、図5に示すように、収納室21は、支持台42における駆動モーター45を囲う壁部42a、動力伝達機構46及び蓋47により、第2収納室21bと、駆動モーター45が配置された第1収納室21aとに仕切られる。これにより、駆動モーター45が配置された第1収納室21aは、第2吹出流路25と連通する第2収納室21bと隔てられる。すなわち、第1収納室21aは、吹出流路5と隔てられる。なお、支持台42には、該支持台42の壁部42aと収納室21の内周壁との間等、気密性を確保したい箇所にシール材42bが設けられている。また、蓋47にも、該蓋47と収納室21の開口部周辺等、気密性を確保したい箇所にシール材47aが設けられている。なお、壁部42aについては、図7も参照されたい。 On the other hand, in the state where the drive device 44 is stored in the storage chamber 21, as shown in FIG. 5, the storage chamber 21 includes the wall portion 42 a surrounding the drive motor 45 in the support 42, the power transmission mechanism 46 and the lid 47. The second storage chamber 21b is divided into a first storage chamber 21a in which the drive motor 45 is disposed. As a result, the first storage chamber 21 a in which the drive motor 45 is disposed is separated from the second storage chamber 21 b in communication with the second outlet flow passage 25. That is, the first storage room 21 a is separated from the blowout flow path 5. A sealing material 42 b is provided on the support 42 at a position where air tightness is to be secured, such as between the wall 42 a of the support 42 and the inner peripheral wall of the storage chamber 21. The lid 47 is also provided with a sealing material 47 a at a position where airtightness is to be secured, such as around the opening of the lid 47 and the storage chamber 21. For the wall portion 42a, see also FIG.
 この際、蓋47は、流路22となる分だけ空くように、収納室21の下部開口を覆う。ここで、左右風向ケースメント20の下面部と化粧パネル30の上面部との間に設けられたシール材92は、図3に二点鎖線で配置範囲92aとして示すように、第2吹出流路25の外周を囲むように設けられている。このため、流路22は、シール材92で覆われていない。したがって、駆動モーター45が配置された第1収納室21aは、吸込流路4と連通している。すなわち、筐体1の一部である左右風向ケースメント20は、吹出流路5と隔てられ、吸込流路4と連通する第1収納室21aを有している。そして、駆動モーター45は、該第1収納室21aに収納されている。
 ここで、第1収納室21aが、本発明の収納室に相当する。
At this time, the lid 47 covers the lower opening of the storage chamber 21 so as to be open for the flow path 22. Here, the sealing material 92 provided between the lower surface portion of the left and right wind direction casement 20 and the upper surface portion of the decorative panel 30 is a second outlet flow path as shown as a placement range 92a in FIG. It is provided so that the outer periphery of 25 may be enclosed. Therefore, the flow path 22 is not covered by the sealing material 92. Therefore, the first storage chamber 21 a in which the drive motor 45 is disposed is in communication with the suction passage 4. That is, the left and right wind direction casement 20 which is a part of the housing 1 is separated from the blowout flow passage 5 and has a first storage chamber 21 a communicating with the suction flow passage 4. The drive motor 45 is accommodated in the first accommodation chamber 21a.
Here, the first storage room 21a corresponds to the storage room of the present invention.
 なお、第1収納室21aと吸込流路4とを連通する流路は、流路22に限定されない。例えば、第1収納室21aと吸込流路4とを連通する貫通孔又は溝部等を左右風向ケースメント20及び化粧パネル30の少なくとも一方に形成し、第1収納室21aと吸込流路4とを連通する流路としてもよい。 In addition, the flow path which connects the 1st storage chamber 21a and the suction flow path 4 is not limited to the flow path 22. FIG. For example, a through hole or a groove communicating the first storage chamber 21a with the suction flow passage 4 is formed in at least one of the left and right wind direction casement 20 and the decorative panel 30, and the first storage chamber 21a and the suction flow passage 4 are formed. It is good also as a channel which connects.
 上述のように構成された左右風向調節部40においては、まず、複数の左右風向調節板41、支持台42、連結部材43及び駆動装置44が、一体品として組み立てられる。その後、支持台42が、例えばネジ止め等により、左右風向ケースメント20に着脱自在に取り付けられる。すなわち、本実施の形態1に係る左右風向調節部40は、一体品として左右風向ケースメント20から着脱自在な構成となっている。例えば、粉塵等で吹出流路5内が汚れた際、左右風向調節部40を着脱して吹出流路5内を清掃しなければならない場合がある。この際、本実施の形態1に係る室内機100においては、左右風向ケースメント20から左右風向調節部40を一体品として着脱出来るので、清掃性が向上する。また例えば、本実施の形態1に係る室内機100においては、左右風向調節板41等が損傷した際、左右風向調節部40を一体品として左右風向ケースメント20から取り外して、左右風向調節板41等の交換を行える。このように、本実施の形態1に係る室内機100には、左右風向ケースメント20から左右風向調節部40を一体品として着脱出来るので、メンテナンス性が向上する。 In the left and right wind direction adjusting unit 40 configured as described above, first, the plurality of left and right wind direction adjusting plates 41, the support base 42, the connecting member 43, and the drive device 44 are assembled as an integral product. Thereafter, the support 42 is detachably attached to the left and right wind direction casement 20 by, for example, screwing. That is, the left and right wind direction adjusting unit 40 according to the first embodiment is configured to be removable from the left and right wind direction casement 20 as an integrated product. For example, when the inside of the blowout flow path 5 is contaminated with dust or the like, it may be necessary to attach and detach the left and right air direction adjustment unit 40 and clean the inside of the blowout flow path 5. Under the present circumstances, in the indoor unit 100 which concerns on this Embodiment 1, since the left-right wind direction adjustment part 40 can be attached or detached as integral goods from the left-right wind direction casement 20, cleaning property improves. In addition, for example, in the indoor unit 100 according to the first embodiment, when the left and right wind direction adjusting plate 41 and the like are damaged, the left and right wind direction adjusting unit 40 is removed from the left and right wind direction casement 20 as an integrated product. Etc. can be exchanged. Thus, in the indoor unit 100 according to the first embodiment, the left / right wind direction adjusting unit 40 can be attached to and detached from the left / right wind direction casement 20 as an integral product, and thus the maintenance performance is improved.
 続いて、本実施の形態1に係る室内機100の運転動作について説明する。
 図2に吸込空気101及び吹出空気102として矢印で示すように、送風機6が回転することによって、空調対象空間の空気は、吸込口2から筐体1内に吸い込まれ、吸込流路4を通って熱交換器7に流入する。そして、熱交換器7に流入した空調対象空間の空気は、熱交換器7を通る際に該熱交換器7の冷媒流路内を流れる冷媒と熱交換して空調空気となり、吹出流路5を通って吹出口3から空調対象空間へ吹き出される。
Subsequently, the operation of the indoor unit 100 according to the first embodiment will be described.
As indicated by arrows in FIG. 2 as suction air 101 and blow-off air 102, the air in the space to be air-conditioned is sucked into the housing 1 from the suction port 2 by the rotation of the blower 6, and passes through the suction flow path 4. Flows into the heat exchanger 7. Then, the air in the air-conditioned space that has flowed into the heat exchanger 7 exchanges heat with the refrigerant flowing in the refrigerant flow path of the heat exchanger 7 when passing through the heat exchanger 7 and becomes air conditioned air. Through the air outlet 3 to the air conditioning target space.
 この際、上下風向調節板51の傾斜角度を調節することにより、吹出口3から吹き出される空調空気の上下方向の角度を調節することが出来る。また、左右風向調節板41の傾斜角度を調節することにより、吹出口3から吹き出される空調空気の横方向の角度を調節することが出来る。すなわち、上下風向調節板51及び左右風向調節板41の傾斜角度を調節することにより、吹出口3から吹き出される空調空気の角度を、上下左右任意の角度に調節出来る。 At this time, by adjusting the inclination angle of the up and down wind direction adjusting plate 51, the up and down direction angle of the conditioned air blown out from the blowout port 3 can be adjusted. In addition, by adjusting the inclination angle of the left and right wind direction adjusting plate 41, it is possible to adjust the lateral angle of the conditioned air blown out from the air outlet 3. That is, by adjusting the inclination angles of the vertical air flow direction adjustment plate 51 and the horizontal air flow direction adjustment plate 41, the angle of the conditioned air blown out from the blowout port 3 can be adjusted to any angle in the vertical and horizontal directions.
 なお、上下風向調節板51及び左右風向調節板41の傾斜角度を固定することにより、吹出口3から吹き出される空調空気の角度を固定してもよい。また、上下風向調節板51及び左右風向調節板41を動かし続け、上下風向調節板51及び左右風向調節板41の傾斜角度を連続的に変化させてもよい。また、上下風向調節板51は、吹出流路5毎に、それぞれ独立して動作してもよいし、連動して動作してもよい。左右風向調節板41もまた、吹出流路5に設けられた左右風向調節板41毎に、独立して動作してもよいし、連動して動作してもよい。 The angle of the conditioned air blown out from the outlet 3 may be fixed by fixing the inclination angles of the vertical air flow direction adjustment plate 51 and the horizontal air flow direction adjustment plate 41. Further, the inclination angles of the vertical wind direction adjusting plate 51 and the horizontal wind direction adjusting plate 41 may be continuously changed by continuously moving the vertical wind direction adjusting plate 51 and the horizontal wind direction adjusting plate 41. In addition, the vertical wind direction adjusting plate 51 may operate independently for each of the blowout flow paths 5, or may operate in conjunction with each other. The left and right wind direction adjusting plates 41 may also operate independently or interlockingly for each of the left and right wind direction adjusting plates 41 provided in the outlet flow passage 5.
 ここで、上述のように、本実施の形態1に係る室内機100においては、吹出流路5と隔てられ、吸込流路4と連通する第1収納室21aに、左右風向調節部40の駆動モーター45が配置されている。このため、冷房運転時、駆動モーター45は、熱交換器7で冷却された空気に直接さらされることがない。このため、本実施の形態1に係る室内機100においては、冷房運転時、熱交換器7で冷却された空気と発熱した駆動モーター45との温度差によって該駆動モーター45に結露が生じることを防止出来る。また、暖房運転時、駆動モーター45は、熱交換器7で加熱された空気に直接さらされることがない。また、暖房運転時、駆動モーター45は、吸込流路4に吸い込まれた空気によって冷却される。このため、本実施の形態1に係る室内機100においては、暖房運転時、熱交換器7で加熱された空気によって駆動モーター45の温度が上昇してしまうことを防止出来る。 Here, as described above, in the indoor unit 100 according to the first embodiment, the driving of the left and right wind direction adjusting unit 40 in the first storage chamber 21a separated from the blowout flow path 5 and in communication with the suction flow path 4 A motor 45 is arranged. Therefore, during the cooling operation, the drive motor 45 is not directly exposed to the air cooled by the heat exchanger 7. Therefore, in the indoor unit 100 according to the first embodiment, condensation occurs in the drive motor 45 due to the temperature difference between the air cooled by the heat exchanger 7 and the heat generated drive motor 45 during the cooling operation. It can prevent. Also, during the heating operation, the drive motor 45 is not directly exposed to the air heated by the heat exchanger 7. Further, during the heating operation, the drive motor 45 is cooled by the air sucked into the suction flow path 4. Therefore, in the indoor unit 100 according to the first embodiment, it is possible to prevent the temperature of the drive motor 45 from rising due to the air heated by the heat exchanger 7 during the heating operation.
 このように、本実施の形態1に係る室内機100においては、熱交換器7と熱交換後の空気の温度の影響を駆動モーター45が受けることを防止出来る。このため、本実施の形態1に係る室内機100は、駆動モーター45の耐久性を確保することが出来る。なお、当該効果は、室内機本体10、左右風向ケースメント20及び化粧パネル30で筐体1が構成されている場合に限定されるものではない。例えば、室内機本体10と左右風向ケースメント20とを一体形成した筐体1においても、当該効果を得ることが出来る。すなわち、筐体1に、吹出流路5と隔てられ、吸込流路4と連通する第1収納室21aが設けられていればよい。そして、この第1収納室21aに駆動モーター45が収納されていれば、当該効果を得ることが出来る。 As described above, in the indoor unit 100 according to the first embodiment, the drive motor 45 can be prevented from being affected by the temperature of air after heat exchange with the heat exchanger 7. Therefore, the indoor unit 100 according to the first embodiment can ensure the durability of the drive motor 45. In addition, the said effect is not limited when the case 1 is comprised by the indoor unit main body 10, the right and left wind direction casement 20, and the decorative panel 30. FIG. For example, even in the case 1 in which the indoor unit body 10 and the left and right wind direction casement 20 are integrally formed, the effect can be obtained. That is, the housing 1 may be provided with the first storage chamber 21 a separated from the blowout flow path 5 and in communication with the suction flow path 4. If the drive motor 45 is stored in the first storage chamber 21a, the effect can be obtained.
 以上、本実施の形態1に係る室内機100は、下面部に吸込口2及び吹出口3が開口した筐体1を備えている。また、本実施の形態1に係る室内機100は、送風機6、熱交換器7及び左右風向調節部40を備えている。送風機6は、筐体1に収納され、空調対象空間の空気を吸込口2から筐体1に吸い込み、吹出口3から吹き出すものである。熱交換器7は、筐体1に収納され、内部に流れる冷媒と筐体1内に吸い込まれた空気とを熱交換させるものである。左右風向調節部40は、吹出口3から吹き出される空気の横方向の角度を調節するものである。すなわち、筐体1には、吸込口2と熱交換器7とを連通させる吸込流路4と、熱交換器7と吹出口3とを連通させる吹出流路5とが形成されている。また、左右風向調節部40は、吹出流路5内において横方向に規定の間隔を空けて配置された複数の左右風向調節板41と、駆動モーター45を有し、該駆動モーター45の動力によって複数の左右風向調節板41を揺動させる駆動装置44とを備えている。また、筐体1は、吹出流路5と隔てられ、吸込流路4と連通する第1収納室21aを有している。そして、駆動モーター45は、第1収納室21aに収納されている。 As mentioned above, the indoor unit 100 which concerns on this Embodiment 1 is equipped with the housing | casing 1 which the suction inlet 2 and the blower outlet 3 opened in the lower surface part. Further, the indoor unit 100 according to the first embodiment includes the blower 6, the heat exchanger 7, and the left and right wind direction adjusting unit 40. The blower 6 is housed in the housing 1, sucks the air of the space to be air-conditioned from the suction port 2 into the housing 1, and blows it out from the outlet 3. The heat exchanger 7 is accommodated in the housing 1 and exchanges heat between the refrigerant flowing inside and the air sucked into the housing 1. The left and right wind direction adjusting unit 40 is to adjust the lateral angle of the air blown out from the air outlet 3. That is, in the housing 1, a suction flow path 4 for communicating the suction port 2 and the heat exchanger 7 and a blowoff flow path 5 for communicating the heat exchanger 7 and the blowout port 3 are formed. In addition, the left and right wind direction adjustment unit 40 has a plurality of left and right wind direction adjustment plates 41 disposed at predetermined intervals in the lateral direction in the blowout flow path 5 and a drive motor 45, and the power of the drive motor 45 And a drive device 44 for swinging the plurality of left and right wind direction adjusting plates 41. Further, the housing 1 has a first storage chamber 21 a separated from the blowout flow passage 5 and in communication with the suction flow passage 4. The drive motor 45 is accommodated in the first accommodation chamber 21a.
 このように構成された室内機100においては、熱交換器7と熱交換後の空気の温度の影響を駆動モーター45が受けることを防止出来る。このため、本実施の形態1に係る室内機100は、駆動モーター45の耐久性を確保することが出来る。 In the indoor unit 100 configured as described above, the drive motor 45 can be prevented from being affected by the temperature of the heat exchanger 7 and the temperature of the air after heat exchange. Therefore, the indoor unit 100 according to the first embodiment can ensure the durability of the drive motor 45.
 また、本実施の形態1に係る室内機100においては、第1収納室21aは、筐体1を下面部側から観察した状態において、筐体1の角部に配置されている。筐体1の角部は、室内機100の構成要素を配置しづらい箇所である。このため、第1収納室21aを筐体1の角部に配置し、該第1収納室21aに駆動モーター45を収納することにより、筐体1の角部を有効活用することが出来る。 Further, in the indoor unit 100 according to the first embodiment, the first storage room 21 a is disposed at a corner of the housing 1 in a state where the housing 1 is observed from the lower surface side. The corner of the housing 1 is a location where the components of the indoor unit 100 are difficult to arrange. Therefore, by arranging the first storage room 21a at the corner of the housing 1 and storing the drive motor 45 in the first storage room 21a, the corner of the housing 1 can be effectively used.
 なお、左右風向調節部40は、例えば図8に示すように、吹出流路5と連通する箇所に配置されている部品と、吸込流路4と連通する箇所に配置されている部品との間に、断熱材93を有していてもよい。 For example, as shown in FIG. 8, the left / right air flow direction adjustment unit 40 is between the component disposed at the location communicating with the blowout channel 5 and the component disposed at the location communicating with the suction channel 4. In addition, the heat insulator 93 may be provided.
 図8は、本発明の実施の形態1に係る空気調和機の室内機の別の一例を示す要部拡大図である。この図8は、図5と同じ位置での断面を示している。
 図8に示す室内機100の左右風向調節部40は、動力伝達機構46と駆動モーター45との間に、断熱材93を有している。断熱材93は、例えば、発泡ウレタンで構成されている。
FIG. 8 is a main part enlarged view showing another example of the indoor unit of the air conditioner according to Embodiment 1 of the present invention. FIG. 8 shows a cross section at the same position as FIG.
The left and right wind direction adjustment unit 40 of the indoor unit 100 shown in FIG. 8 has a heat insulating material 93 between the power transmission mechanism 46 and the drive motor 45. The heat insulating material 93 is made of, for example, urethane foam.
 上述のように、第2収納室21bは、吹出流路5の一部を構成する第2吹出流路25と連通している。そして、左右風向調節部40の動力伝達機構46は、第2収納室21bに収納されている。このため、動力伝達機構46は、冷房運転時、熱交換器7で冷却された空気によって冷却される。また、動力伝達機構46は、暖房運転時、熱交換器7で加熱された空気によって加熱される。ここで、図5で示した左右風向調節部40は、動力伝達機構46と駆動モーター45とが直接接続されていた。このため、動力伝達機構46と駆動モーター45との間の熱交換により、駆動モーター45は、熱交換器7と熱交換後の空気の温度の影響を若干受けることとなる。一方、図8に示す左右風向調節部40は、断熱材93により、動力伝達機構46と駆動モーター45との間の熱交換を防止出来る。したがって、図8のように左右風向調節部40を構成することにより、熱交換器7と熱交換後の空気の温度の影響を駆動モーター45が受けることをさらに防止出来る。したがって、図8のように左右風向調節部40を構成することにより、駆動モーター45の耐久性をさらに確保することが出来る。 As described above, the second storage chamber 21 b communicates with the second blow-off flow path 25 that constitutes a part of the blow-out flow path 5. The power transmission mechanism 46 of the left and right wind direction adjusting unit 40 is accommodated in the second accommodation chamber 21 b. Therefore, the power transmission mechanism 46 is cooled by the air cooled by the heat exchanger 7 during the cooling operation. Further, the power transmission mechanism 46 is heated by the air heated by the heat exchanger 7 during the heating operation. Here, in the left and right wind direction adjusting unit 40 shown in FIG. 5, the power transmission mechanism 46 and the drive motor 45 are directly connected. Therefore, the heat exchange between the power transmission mechanism 46 and the drive motor 45 causes the drive motor 45 to be somewhat affected by the temperature of the heat exchanger 7 and the temperature of the air after the heat exchange. On the other hand, the left and right wind direction adjusting unit 40 shown in FIG. 8 can prevent heat exchange between the power transmission mechanism 46 and the drive motor 45 by the heat insulating material 93. Therefore, by configuring the left and right wind direction adjusting unit 40 as shown in FIG. 8, it is possible to further prevent the drive motor 45 from being influenced by the temperature of air after heat exchange with the heat exchanger 7. Therefore, the durability of the drive motor 45 can be further secured by configuring the left and right wind direction adjusting unit 40 as shown in FIG.
実施の形態2.
 左右風向調節部40の駆動モーター45を収納する収納室21は、実施の形態1で示した位置に限定されない。例えば本実施の形態2で示す位置に収納室21を設けてもよい。なお、本実施の形態2において、特に記述しない項目については実施の形態1と同様とし、同一の機能及び構成については同一の符号を用いて述べることとする。

 本実施の形態2に係る室内機100においては、収納室21は、下方から左右風向ケースメント20を観察した状態において、第2吹出流路25と第2吸込流路24との間に配置されている。換言すると、収納室21は、筐体1を下面部側から観察した状態において、吹出流路5と吸込流路4との間に配置されている。収納室21に駆動装置44が収納されていない状態においては、収納室21の外周側の側面部は、第2吹出流路25の内周側の側面部と連通している。また、収納室21の内周側の側面部は、第2吸込流路24と連通している。なお、本実施の形態2では、収納室21の内周側の側面部と対向する位置に、板部材28が設けられている。この板部材28は、収納室21に収納されている駆動モーター45に作業者等が触れることを防止するためのものであり、収納室21と第2吸込流路24との間を塞ぐものではない。このため、図11及び図13に示すように、収納室21と第2吸込流路24との間を連通させる流路22は確保されている。 In the indoor unit 100 according to the second embodiment, the storage room 21 is disposed between the second blowout flow path 25 and the second suction flow path 24 in a state in which the left and right wind direction casement 20 is observed from below. ing. In other words, the storage chamber 21 is disposed between the blowout passage 5 and the suction passage 4 in a state where the housing 1 is observed from the lower surface side.
