　排気口・吸気口開閉部３４ａは、回転切替え部材３４の外周を仮に円筒形と見た場合、１／４周分の円筒部分に相当した形状を有する。吸排気口開閉部３４ｂは、回転切替え部材３４の筐体主部３２側の端部に排気口・吸気口開閉部３４ａと隣り合って位置し、中心角が９０°の扇形の平板形状を有する。仕切部３４ｃは、回転切替え部材３４の中心を通るように設けれ、回転切替え部材３４の軸方向に延びる平板形状の板部である。仕切部３４ｃは、回転切替え部材３４の内部を、排気口・吸気口開閉部３４ａおよび吸排気口開閉部３４ｂが存在する領域と、排気口・吸気口開閉部３４ａおよび吸排気口開閉部３４ｂが存在しない領域とを仕切っている。 When the outer periphery of the rotation switching member 34 is assumed to be cylindrical, the exhaust port / intake port opening / closing part 34a has a shape corresponding to a cylindrical portion corresponding to ¼ circumference. The intake / exhaust port opening / closing part 34b is positioned adjacent to the exhaust port / intake opening / closing part 34a at the end of the rotation switching member 34 on the housing main part 32 side, and has a fan-shaped flat plate shape with a central angle of 90 °. . The partition portion 34 c is a flat plate portion that is provided so as to pass through the center of the rotation switching member 34 and extends in the axial direction of the rotation switching member 34. The partition portion 34c includes an interior of the rotation switching member 34, a region where the exhaust port / intake port opening / closing portion 34a and the intake / exhaust port opening / closing portion 34b exist, and an exhaust port / intake port opening / closing portion 34a and an intake / exhaust port opening / closing portion 34b The area that does not exist is partitioned.
　これにより、回転切替え部材３４は、回転することにより、通常モード位置（通常状態）、吸気モード位置（吸気状態）および排気モード位置（排気状態）を採り得るようになっている。 Thereby, the rotation switching member 34 can take the normal mode position (normal state), the intake mode position (intake state), and the exhaust mode position (exhaust state) by rotating.
　通常モード位置は、排気口・吸気口開閉部３４ａによって排気口３６ａを塞ぎ、吸排気口開閉部３４ｂによって吸排気口３６ｄを塞き、かつ吸気口３６ｂを開放した状態とする位置である（図１１の（ｂ）参照）。 The normal mode position is a position where the exhaust port 36a is closed by the exhaust port / intake port opening / closing portion 34a, the intake / exhaust port 36d is closed by the intake / exhaust port opening / closing portion 34b, and the intake port 36b is opened (see FIG. 11 (b)).
　吸気モード位置は、排気口・吸気口開閉部３４ａが通常モード位置から９０°回転し、吸排気口３６ｄと吸気口３６ｂとを通気可能とし、排気口３６ａと吸排気口３６ｄおよび吸気口３６ｂとの通気を遮断する位置である（図１２の（ｂ）参照）。 In the intake mode position, the exhaust port / intake port opening / closing part 34a is rotated 90 ° from the normal mode position so that the intake / exhaust port 36d and the intake port 36b can be ventilated, and the exhaust port 36a, the intake / exhaust port 36d, and the intake port 36b This is a position where the ventilation of air is blocked (see FIG. 12B).
　排気モード位置は、排気口・吸気口開閉部３４ａが吸気モード位置から同方向へ９０°回転し、排気口３６ａと吸排気口３６ｄとの通気を可能とし、仕切部３４ｃによって、排気口３６ａおよび吸排気口３６ｄと吸気口３６ｂとの通気を遮断する位置である（図１３の（ｂ）参照）。 The exhaust mode position is such that the exhaust port / intake port opening / closing part 34a rotates 90 ° in the same direction from the intake mode position to allow ventilation between the exhaust port 36a and the intake / exhaust port 36d. This is a position where the ventilation of the intake / exhaust port 36d and the intake port 36b is blocked (see FIG. 13B).
　（空気調和機の制御装置）
　図１４は、本実施形態の空気調和機の制御装置の構成を示すブロック図である。図１４に示すように、空気調和機の制御装置は、例えばマイクロコンピュータからなる制御部４１および記憶部４２を備えている。制御部４１には受信部４３が接続され、受信部４３は、ユーザが操作するリモートコントローラ（以下、単にリモコンと称する）４４からの指令を受信する。リモコン４４では、室内機１を備えた空気調和機に対して空調モードの設定が可能である。また、リモコン４４では、室内機１に対し、吸排気モードとして、通常モード、吸気モードおよび排気モードの設定が可能である。なお、空調モードは、冷房または暖房等を行うモードである。 (Control device for air conditioner)
FIG. 14 is a block diagram showing the configuration of the control device for the air conditioner of the present embodiment. As shown in FIG. 14, the control device for the air conditioner includes a control unit 41 and a storage unit 42 formed of, for example, a microcomputer. A receiving unit 43 is connected to the control unit 41, and the receiving unit 43 receives a command from a remote controller (hereinafter simply referred to as a remote controller) 44 operated by a user. The remote control 44 can set the air conditioning mode for the air conditioner including the indoor unit 1. The remote controller 44 can set the normal mode, the intake mode, and the exhaust mode as the intake / exhaust mode for the indoor unit 1. The air conditioning mode is a mode for performing cooling or heating.
　制御部４１は、リモコン４４からの指令に応じて、空調部４５、ファンモータ２０および切替えモータ３１の動作を制御する。 The control unit 41 controls operations of the air conditioning unit 45, the fan motor 20, and the switching motor 31 in accordance with a command from the remote controller 44.
　空調部４５は、冷凍サイクルを実行する部分であり、蒸発器、凝縮機および圧縮機等、冷凍サイクルを実行するための構成を有する。空調部４５は、室内機１および室外機４６に亘って構成されている。 The air conditioning unit 45 is a part that executes a refrigeration cycle, and has a configuration for executing the refrigeration cycle, such as an evaporator, a condenser, and a compressor. The air conditioning unit 45 is configured across the indoor unit 1 and the outdoor unit 46.
　記憶部４２は、吸排気装置２１の回転切替え部材３４を通常モード位置、吸気モード位置および排気モード位置に配置する場合の切替えモータ３１に対する制御内容を記憶している。また、記憶部４２は、制御部４１の制御により、運転停止直前の運転モードや温度設定、リモコン４４によって設定された運転モードや設定温度を記憶する。 The storage unit 42 stores the control contents for the switching motor 31 when the rotation switching member 34 of the intake / exhaust device 21 is disposed at the normal mode position, the intake mode position, and the exhaust mode position. Further, the storage unit 42 stores the operation mode and temperature setting immediately before the operation stop and the operation mode and set temperature set by the remote controller 44 under the control of the control unit 41.
　（吸排気装置２１および室内機１の動作）
　上記の構成において、本実施形態の空気調和機の動作について以下に説明する。図１５は、室内機１の吸気モードの状態の図１におけるＣ－Ｃ断面図である。図１６は、室内機１の排気モードの状態の図１におけるＣ－Ｃ断面図である。 (Operations of intake / exhaust device 21 and indoor unit 1)
In the above configuration, the operation of the air conditioner of the present embodiment will be described below. FIG. 15 is a cross-sectional view taken along the line CC in FIG. 1 in the state of the intake mode of the indoor unit 1. FIG. 16 is a cross-sectional view taken along the line CC in FIG. 1 in the exhaust mode state of the indoor unit 1.
　空気調和機が空調モードの場合、送風ファン１２が回転することにより、図４に示すように、送風ファン１２の周りは低圧領域１８となり、送風ファン１２と熱交換器１３との間は、高圧領域１９となる。この点は、図３によって前述したとおりである。なお、吸排気装置２１の吸排気管３５の周りは、中圧領域（大気圧領域）３７である。 When the air conditioner is in the air-conditioning mode, the blower fan 12 rotates, so that the area around the blower fan 12 becomes a low pressure region 18 as shown in FIG. 4, and the high pressure between the blower fan 12 and the heat exchanger 13 is high. Region 19 is formed. This point is as described above with reference to FIG. In addition, around the intake / exhaust pipe 35 of the intake / exhaust device 21 is an intermediate pressure region (atmospheric pressure region) 37.
　　（通常モード）
　室内機１（吸排気装置２１）の吸排気モードは、空気調和機が空調モードの場合、通常モードとなる。この場合、吸排気装置２１では、図１１の（ａ）（ｂ）に示すように、回転切替え部材３４は、切替えモータ３１に駆動されて通常モード位置に回転する。切替えモータ３１の回転は、制御部４１にて制御される。この点は、吸気モードおよび排気モードの場合も同様である。 (Normal mode)
The intake / exhaust mode of the indoor unit 1 (intake / exhaust device 21) is the normal mode when the air conditioner is in the air conditioning mode. In this case, in the intake / exhaust device 21, as shown in FIGS. 11A and 11B, the rotation switching member 34 is driven by the switching motor 31 and rotates to the normal mode position. The rotation of the switching motor 31 is controlled by the control unit 41. This also applies to the intake mode and the exhaust mode.
　通常モード位置では、吸排気装置２１は、排気口・吸気口開閉部３４ａによって吸気口３６ｂを塞ぎ、吸排気口開閉部３４ｂによって吸排気口３６ｄを塞き、かつ吸気口３６ｂを開放した状態とする。これにより、室内機１では、図４に示すように、吸排気装置２１による室外の空気の吸気、および室内の空気の排気は行われない。 In the normal mode position, the intake / exhaust device 21 has a state in which the intake port 36b is blocked by the exhaust port / intake port opening / closing portion 34a, the intake / exhaust port 36d is closed by the intake / exhaust port opening / closing portion 34b, and the intake port 36b is opened. To do. Thereby, in the indoor unit 1, as shown in FIG. 4, the intake / exhaust device 21 does not perform intake of outdoor air and exhaust of indoor air.
　　（吸気モード）
　室内機１は、空調モードが停止している場合に、吸排気モードを吸気モードに設定することができる。ただし、送風ファン１２は回転する。吸気モードの場合、吸排気装置２１では、図１２の（ａ）（ｂ）に示すように、回転切替え部材３４は、切替えモータ３１に駆動されて吸気モード位置に回転する。 (Intake mode)
The indoor unit 1 can set the intake / exhaust mode to the intake mode when the air conditioning mode is stopped. However, the blower fan 12 rotates. In the intake mode, in the intake / exhaust device 21, as shown in FIGS. 12A and 12B, the rotation switching member 34 is driven by the switching motor 31 and rotates to the intake mode position.
　吸気モード位置では、回転切替え部材３４は、吸排気口３６ｄと吸気口３６ｂとの通気可能とし、排気口３６ａと吸排気口３６ｄおよび吸気口３６ｂとの通気を遮断する。これにより、室内機１では、図１５に示すように、中圧領域３７の空気、すなわち外気が吸排気管３５および吸排気口３６ｄから吸排気筐体３６の内部に入り込み、吸気口３６ｂから送風ファン１２の周りの低圧領域１８に流出する。この空気は、送風ファン１２によって吹出口１４から室内へ吹き出される。このように、吸気モードでは、外気が吸排気装置２１を介して室内機１の内部に取り込まれ、室内へ供給される。 In the intake mode position, the rotation switching member 34 allows ventilation between the intake / exhaust port 36d and the intake port 36b, and blocks ventilation between the exhaust port 36a, the intake / exhaust port 36d, and the intake port 36b. Thereby, in the indoor unit 1, as shown in FIG. 15, the air in the intermediate pressure region 37, that is, the outside air, enters the inside of the intake / exhaust housing 36 through the intake / exhaust pipe 35 and the intake / exhaust port 36d, and the blower fan from the intake port 36b. 12 to the low pressure region 18 around 12. This air is blown out from the blower outlet 14 into the room by the blower fan 12. Thus, in the intake mode, outside air is taken into the indoor unit 1 via the intake / exhaust device 21 and supplied to the room.
　　（排気モード）
　室内機１は、空調モードが停止している場合に、吸排気モードを排気モードに設定することができる。ただし、送風ファン１２は回転する。排気モードの場合、吸排気装置２１では、図１３の（ａ）（ｂ）に示すように、回転切替え部材３４は、切替えモータ３１に駆動されて排気モード位置に回転する。 (Exhaust mode)
The indoor unit 1 can set the intake / exhaust mode to the exhaust mode when the air-conditioning mode is stopped. However, the blower fan 12 rotates. In the exhaust mode, in the intake / exhaust device 21, as shown in FIGS. 13A and 13B, the rotation switching member 34 is driven by the switching motor 31 and rotates to the exhaust mode position.
　排気モード位置では、回転切替え部材３４は、排気口３６ａと吸排気口３６ｄとの通気を可能とし、仕切部３４ｃによって、排気口３６ａおよび吸排気口３６ｄと吸気口３６ｂとの通気を遮断する。これにより、室内機１では、図１６に示すように、高圧領域１９の空気、すなわち吸込口１１から室内機１の内部へ取り込まれた室内空気が、排気口３６ａから吸排気筐体３６の内部に入り込み、吸排気口３６ｄおよび吸排気管３５から中圧領域３７へ流出する。このように、排気モードでは、室内の空気が吸排気装置２１を介して室外へ排出される。 In the exhaust mode position, the rotation switching member 34 allows ventilation between the exhaust port 36a and the intake / exhaust port 36d, and the partition portion 34c blocks ventilation between the exhaust port 36a, the intake / exhaust port 36d, and the intake port 36b. Thereby, in the indoor unit 1, as shown in FIG. 16, the air in the high pressure region 19, that is, the indoor air taken into the interior of the indoor unit 1 from the suction port 11 is passed through the exhaust port 36a to the inside of the intake / exhaust housing 36. It flows into the intermediate pressure region 37 from the intake / exhaust port 36d and the intake / exhaust pipe 35. Thus, in the exhaust mode, indoor air is exhausted to the outside through the intake / exhaust device 21.
　（吸排気装置２１および室内機１の利点）
　吸排気装置２１は、送風ファン１２の回転によって生じる圧力差を利用して吸排気を行う構成であり、吸排気用の専用のファンが不要となっている。これにより、吸排気装置２１は、室内機１での設置スペースを小さくすることができる。また、吸排気装置２１は、吸排気モードに応じて回転切替え部材３４を所定位置に回転させる切替えモータ３１として、低トルクの小型のステッピングモータを使用することができる。したがって、これによっても設置スペースを小さくすることができる。また、吸排気装置２１は、専用のファンが不要であること、および切替えモータ３１として廉価なステッピングモータを使用できることから、低コストの構成とすることができる。以上により、吸排気装置２１を備えた室内機１は、小型かつ低コストの構成とすることができる。 (Advantages of intake / exhaust device 21 and indoor unit 1)
The intake / exhaust device 21 is configured to perform intake / exhaust using a pressure difference generated by the rotation of the blower fan 12, and a dedicated fan for intake / exhaust is not required. Thereby, the intake / exhaust device 21 can reduce the installation space in the indoor unit 1. The intake / exhaust device 21 can use a small stepping motor with low torque as the switching motor 31 that rotates the rotation switching member 34 to a predetermined position in accordance with the intake / exhaust mode. Therefore, the installation space can be reduced also by this. In addition, since the intake / exhaust device 21 does not require a dedicated fan, and an inexpensive stepping motor can be used as the switching motor 31, it can be configured at a low cost. As described above, the indoor unit 1 including the intake / exhaust device 21 can be configured to be small and low-cost.
　なお、本実施形態では、吸排気装置２１は、空気調和機が空調機能を停止している状態において、吸気または排気を行う構成として説明した。しかしながら、吸排気装置２１は、送風ファン１２が回転していれば吸気または排気を行うことができる。したがって、吸排気装置２１は、空気調和機が送風ファン１２を回転させて空調機能を行っている状態でも吸気または排気を行う構成としてもよい。この点は、以下の他の実施形態においても同様である。 In the present embodiment, the intake / exhaust device 21 has been described as a configuration that performs intake or exhaust while the air conditioner stops the air conditioning function. However, the intake / exhaust device 21 can perform intake or exhaust if the blower fan 12 is rotating. Therefore, the intake / exhaust device 21 may be configured to perform intake or exhaust even in a state where the air conditioner rotates the blower fan 12 to perform the air conditioning function. This also applies to the other embodiments described below.

17A is a perspective view of the intake / exhaust device 22 of the present embodiment, and FIG. 17B is an exploded perspective view of the intake / exhaust device 22 shown in FIG. 17A.
　本実施形態の室内機１は、前記吸排気装置２１に代えて、図１７の（ａ）（ｂ）に示す吸排気装置２２を備えている。前記吸排気装置２１は、切替えモータ３１の駆動力を回転切替え部材３４に直接伝えて回転切替え部材３４を回転させていた。これに対し、吸排気装置２２は、切替えモータ３１の駆動力を互いに噛み合う第１ギヤ５１および第２ギヤ５２を介して回転切替え部材３４に伝え、回転切替え部材３４を回転させている。したがって、吸排気装置２２では、第１ギヤ５１の軸穴に切替えモータ３１の駆動軸が嵌合し、第２ギヤ５２の軸穴に回転切替え部材３４の中心軸３４ｄが嵌合している。 The indoor unit 1 of the present embodiment includes an intake / exhaust device 22 shown in FIGS. 17A and 17B instead of the intake / exhaust device 21. The intake / exhaust device 21 directly transmits the driving force of the switching motor 31 to the rotation switching member 34 to rotate the rotation switching member 34. On the other hand, the intake / exhaust device 22 transmits the driving force of the switching motor 31 to the rotation switching member 34 via the first gear 51 and the second gear 52 that mesh with each other to rotate the rotation switching member 34. Therefore, in the intake / exhaust device 22, the drive shaft of the switching motor 31 is fitted in the shaft hole of the first gear 51, and the central shaft 34 d of the rotation switching member 34 is fitted in the shaft hole of the second gear 52.
　筐体副部３３は上部に上方へ延びた延設部３３ａを有し、この延設部３３ａは、第１ギヤ５１の歯面を覆っている。切替えモータ３１は延設部３３ａに固定されている。また、筐体副部３３は、内部に第１ギヤ５１および第２ギヤ５２を収容できるように、吸排気装置２１の筐体副部３３よりも軸方向の幅が大きくなっている。吸排気装置２２のその他の構成は吸排気装置２１と同様である。 The housing sub-part 33 has an extension part 33 a extending upward at the upper part, and this extension part 33 a covers the tooth surface of the first gear 51. The switching motor 31 is fixed to the extending portion 33a. Further, the housing sub-portion 33 has a larger axial width than the housing sub-portion 33 of the intake / exhaust device 21 so that the first gear 51 and the second gear 52 can be accommodated therein. Other configurations of the intake / exhaust device 22 are the same as those of the intake / exhaust device 21.
　また、吸排気装置２２および吸排気装置２２を備えた室内機１の動作、並びに吸排気装置２２および吸排気装置２２を備えた室内機１の利点は、吸排気装置２１の場合と同様である。 The operation of the indoor unit 1 including the intake / exhaust device 22 and the intake / exhaust device 22 and the advantages of the indoor unit 1 including the intake / exhaust device 22 and the intake / exhaust device 22 are the same as those of the intake / exhaust device 21. .
　〔実施形態３〕

　（吸排気装置２３の構成）
　図１８の（ａ）は、本実施形態の吸排気装置２３の斜視図、図１８の（ｂ）は、図１８の（ａ）に示した吸排気装置２３の分解斜視図である。 (Configuration of intake / exhaust device 23)
18A is a perspective view of the intake / exhaust device 23 of the present embodiment, and FIG. 18B is an exploded perspective view of the intake / exhaust device 23 shown in FIG. 18A.
　本実施形態の室内機１は、前記吸排気装置２１に代えて、図１８の（ａ）（ｂ）に示す吸排気装置２３を備えている。前記吸排気装置２１は、切替えモータ３１の駆動力を回転切替え部材３４に直接伝えて回転切替え部材３４を回転させていた。これに対し、吸排気装置２３は、切替えモータ３１の駆動力を第１ギヤ５１、第２ギヤ５２、およびこれら第１ギヤ５１と第２ギヤ５２との間の第３ギヤ５３を介して回転切替え部材３４に伝え、回転切替え部材３４を回転させている。したがって、吸排気装置２３では、第１ギヤ５１の軸穴に切替えモータ３１の駆動軸が嵌合し、第２ギヤ５２の軸穴に回転切替え部材３４の中心軸３４ｄが嵌合し、第３ギヤ５３が第１ギヤ５１および第２ギヤ５２と噛み合っている。 The indoor unit 1 of the present embodiment includes an intake / exhaust device 23 shown in FIGS. 18A and 18B instead of the intake / exhaust device 21. The intake / exhaust device 21 directly transmits the driving force of the switching motor 31 to the rotation switching member 34 to rotate the rotation switching member 34. In contrast, the intake / exhaust device 23 rotates the driving force of the switching motor 31 via the first gear 51, the second gear 52, and the third gear 53 between the first gear 51 and the second gear 52. The rotation switching member 34 is rotated by transmitting to the switching member 34. Therefore, in the intake / exhaust device 23, the drive shaft of the switching motor 31 is fitted in the shaft hole of the first gear 51, the center shaft 34d of the rotation switching member 34 is fitted in the shaft hole of the second gear 52, and the third The gear 53 is engaged with the first gear 51 and the second gear 52.
　筐体副部３３は、上部に上方へ延びた延設部３３ａを有し、この延設部３３ａは、第１ギヤ５１から第３ギヤ５３の歯面を覆っている。切替えモータ３１は、吸排気装置２２とは異なり、筐体主部３２側に配置されている。吸排気装置２３のその他の構成は吸排気装置２１と同様である。 The housing sub-part 33 has an extension part 33 a extending upward at the upper part, and the extension part 33 a covers the tooth surfaces of the first gear 51 to the third gear 53. Unlike the intake / exhaust device 22, the switching motor 31 is disposed on the housing main part 32 side. Other configurations of the intake / exhaust device 23 are the same as those of the intake / exhaust device 21.
　また、吸排気装置２３および吸排気装置２３を備えた室内機１の動作、並びに吸排気装置２３および吸排気装置２３を備えた室内機１の利点は、吸排気装置２１の場合と同様である。 The operation of the indoor unit 1 including the intake / exhaust device 23 and the intake / exhaust device 23 and the advantage of the indoor unit 1 including the intake / exhaust device 23 and the intake / exhaust device 23 are the same as those of the intake / exhaust device 21. .
