　風向変更装置１００は、室外機２００の排気口２０２から排気される空気の流通方向を変更するための風向変更装置である。風向変更装置１００は、排気口上に配置されている複数の風向板１１と、排気口の中心軸Ｃに対する複数の風向板１１の傾斜角を変更するように設けられている第１駆動部１５と、排気口に対して位置決めされている第１部分２１Ａ及び第１部分２１Ａに対して中心軸Ｃ周りに回転するように設けられており複数の風向板１１を搭載している第２部分２１Ｂとを含む搭載部２１と、第２部分２１Ｂを中心軸Ｃ周りに回転させる第２駆動部２２とを備える。 The wind direction changing device 100 is a wind direction changing device for changing the circulation direction of the air exhausted from the exhaust port 202 of the outdoor unit 200 . The wind direction changing device 100 includes a plurality of wind direction plates 11 arranged above the exhaust port, and a first driving unit 15 provided to change the inclination angles of the plurality of wind direction plates 11 with respect to the central axis C of the exhaust port. , a first portion 21A positioned with respect to the exhaust port, and a second portion 21B provided to rotate about the central axis C with respect to the first portion 21A and carrying a plurality of wind direction plates 11; and a second driving portion 22 that rotates the second portion 21B around the central axis C.
　そのため、風向変更装置１００は、排気口２０２の中心軸Ｃに対する流通方向の傾斜角を変更可能なだけでなく、排気口２０２の中心軸Ｃ周りの流通方向の回転角をも変更可能である。そのため、風向変更装置１００では、従来の風向変更装置と比べて、排気口２０２から排気される空気の流通方向を変更する自由度が高められている。 Therefore, the airflow direction changing device 100 can change not only the inclination angle of the flow direction with respect to the central axis C of the exhaust port 202, but also the rotation angle of the flow direction around the central axis C of the exhaust port 202. Therefore, in the airflow direction changing device 100, the degree of freedom in changing the direction of circulation of the air discharged from the exhaust port 202 is increased compared to the conventional airflow direction changing device.
　風向変更装置１００において、第２部分２１Ｂは、中心軸Ｃに対する径方向において第１部分２１Ａよりも外側に第１部分２１Ａと並んで配置されている。搭載部２１は、径方向において第１部分２１Ａと第２部分２１Ｂとの間に配置されており、第１部分２１Ａ及び第２部分２１Ｂの各々と摺動する第３部分２１Ｃをさらに含む。 In the wind direction changing device 100, the second portion 21B is arranged side by side with the first portion 21A outside the first portion 21A in the radial direction with respect to the central axis C. The mounting portion 21 is arranged radially between the first portion 21A and the second portion 21B, and further includes a third portion 21C that slides on each of the first portion 21A and the second portion 21B.
　このようにすれば、搭載部２１は、例えば中心軸Ｃに沿った方向及び中心軸Ｃに対して傾斜する方向などの荷重を負荷しながらも、中心軸Ｃ周りに高精度に回転できる。 In this way, the mounting portion 21 can rotate around the central axis C with high accuracy while applying loads in directions along the central axis C and in directions inclined with respect to the central axis C, for example.
　風向変更装置１００において、第２駆動部２２は、中心軸Ｃ周りに回転するプーリ２３と、プーリ２３および第２部分２１Ｂの各々の周囲に渡されているベルト２４とを含む。このような第２駆動部２２は、排気口２０２の外部に取り付けられるために排気口２０２からの排気を阻害しない。 In the wind direction changing device 100, the second driving section 22 includes a pulley 23 that rotates around the central axis C, and a belt 24 that extends around each of the pulley 23 and the second portion 21B. Since the second drive unit 22 is attached to the outside of the exhaust port 202 , the second driving unit 22 does not obstruct the exhaust from the exhaust port 202 .
　風向変更装置１００は、複数の風向板１１と、複数の風向板１１の各々を連結している連結部１６とを備えているため、複数の風向板１１の各々の相対的な位置関係を連結部１６により保持した状態で、複数の風向板１１の各々を同時に動かすことができる。そのため、例えば排気口２０２の開口面積が比較的大きい場合にも、排気口２０２から排気される空気の流通方向を特定の方向に変更できる。 Since the wind direction changing device 100 includes the plurality of wind direction plates 11 and the connecting portion 16 connecting each of the plurality of wind direction plates 11, the relative positional relationship of each of the plurality of wind direction plates 11 is connected. Each of the plurality of wind direction plates 11 can be moved simultaneously while being held by the portion 16 . Therefore, for example, even when the opening area of the exhaust port 202 is relatively large, the flow direction of the air exhausted from the exhaust port 202 can be changed to a specific direction.
　さらに、複数の風向板１１は、第１駆動部１５に取り付けられている第１風向板１１Ａと、第１風向板１１Ａと連結部１６を介して連結されている第２風向板１１Ｂとを含む。そのため、風向変更装置１００では、個々の風向板１１を駆動するための複数の駆動部が不要とされており、複数の風向板１１の各々を駆動するための複数の駆動部を備える風向変更装置と比べて製造コストの低減が図られている。 Further, the plurality of wind direction vanes 11 include a first wind direction vane 11A attached to the first drive unit 15 and a second wind direction vane 11B connected to the first wind direction vane 11A via the connecting portion 16. . Therefore, the wind direction changing device 100 does not require a plurality of driving units for driving the individual wind direction plates 11, and the wind direction changing device includes a plurality of driving units for driving each of the plurality of wind direction plates 11. The manufacturing cost is reduced compared to
　室外機ユニット３００は、排気口２０２が形成されている筐体２０１を含む室外機２００と、風向変更装置１００とを備える。 The outdoor unit 300 includes an outdoor unit 200 including a housing 201 in which an exhaust port 202 is formed, and a wind direction changing device 100 .
　室外機ユニット３００は、風向変更装置１００を備えるため、従来の風向変更装置を備える室外機ユニットと比べて、排気口２０２から排気される空気の流通方向を変更する自由度が高められている。 Since the outdoor unit 300 includes the airflow direction changing device 100, the degree of freedom in changing the direction of air exhausted from the exhaust port 202 is increased compared to an outdoor unit having a conventional airflow direction changing device.
　なお、風向変更装置１００は、既設の室外機２００に後付け可能である。
　また、図１～図７では、排気口２０２が上方を向いて開口している構成例を示しているが、排気口２０２の開口方向、すなわち中心軸Ｃの延在方向、は特に制限されない。 Note that the wind direction changing device 100 can be retrofitted to the existing outdoor unit 200 .
1 to 7 show configuration examples in which the exhaust port 202 opens upward, but the opening direction of the exhaust port 202, that is, the extending direction of the central axis C, is not particularly limited.
