- the control device 90 When a cooling operation command is input to the control device 90 via the remote controller 81 or the like, the control device 90 causes the front end portion of the rear side vertical wind direction flap 45 to be lowered as shown in FIGS. 10 and 11.
- the angle of the rear vertical wind direction flap 45 is changed from the closed state when the indoor unit 100 is stopped to the open state during operation.
- the rear upper / lower wind direction flap 45 is controlled at two positions: a position where the indoor unit 100 is stopped and a position where the indoor unit 100 is operating.
- the rear up / down airflow direction flap 45 guides the air blown out from the second airflow path 12 and the third airflow path 13 to the front up / down airflow direction flap 41.
- the rear up / down airflow direction flap 45 is at an arbitrary position between the two positions. This is because it is not necessary to stop the wind direction flap 45, that is, it is not necessary to continuously control the angle of the rear side vertical wind direction flap 45. By controlling the rear up / down wind direction flap 45 in this way, the control of the rear up / down wind direction flap 45 is simplified.
- control device 90 rotates the front-side up / down airflow direction flap 47 until the lower end portion is located above the blower outlet 3 to fully open the front portion of the casing 1 at the blower outlet 3. And the control apparatus 90 starts the axial flow fan 4, and controls the rotation speed of the axial flow fan 4 so that it may become the air volume designated with the remote controller 81 grade
- the axial fan 4 When the axial fan 4 is activated, room air is sucked into the air passage 10 of the casing 1 from the suction port 2. This air is sent to the indoor heat exchanger 20 by the axial fan 4. The air is cooled by the refrigerant flowing in the indoor heat exchanger 20 when passing through the indoor heat exchanger 20. At this time, the air that has passed through the first heat exchanger 21 is blown out to the first air passage 11. Further, the air that has passed through the second heat exchanger 22 and the third heat exchanger 23 is blown out to the second air passage 12. Further, the air that has passed through the fourth heat exchanger 24 is blown out to the third air passage 13.
- the air blown out to the second air passage 12 is a mixture of the air that has passed through the second heat exchanger 22 and the air that has passed through the third heat exchanger 23, that is, the air that has collided. . For this reason, the turbulence of the air flow in the second air passage 12 becomes large, and there is a concern about an increase in pressure loss in the second air passage 12.
- the second air passage 12 includes the front rectifying plate 61 and the rear rectifying plate 65. Therefore, when the air that has passed through the second heat exchanger 22 and the air that has passed through the third heat exchanger 23 are mixed and flow into the second air passage 12, the front rectifying plate 61 and the rear rectifying plate 65 The flow is arranged. Therefore, pressure loss in the second air passage 12 can be suppressed.
- part of the air that has passed through the second heat exchanger 22 flows along the upper surface portion of the front drain pan 31 and flows upward between the second heat exchanger 22 and the third heat exchanger 23.
- This air flow also contributes to an increase in pressure loss in the second air passage 12.
- the air flow is guided between the front drain pan 31 and the front rectifying plate 61 by the upper end portion 62 of the front rectifying plate 61 to adjust the flow. That is, the effect that the pressure loss in the second air passage 12 can be suppressed only by the front side rectifying plate 61 is obtained.
- part of the air that has passed through the third heat exchanger 23 flows along the upper surface portion of the rear drain pan 35, and upwards between the second heat exchanger 22 and the third heat exchanger 23. Flows in. This air flow also contributes to an increase in pressure loss in the second air passage 12.
- the air flow is guided between the rear drain pan 35 and the rear rectifying plate 65 by the upper end portion 66 of the rear rectifying plate 65 to regulate the flow. That is, the effect that the pressure loss in the second air passage 12 can be suppressed only by the rear side rectifying plate 65 is obtained.
- the air flowing between the rear drain pan 35 and the rear rectifying plate 65 is bent forward by the protrusion 37 of the rear drain pan 35 and the lower end 67 of the rear rectifying plate 65. For this reason, the pressure loss when the air blown out from the second air passage 12 is bent forward by the rear side vertical wind direction flap 45 can also be suppressed.
- the air blown out from the first air passage 11 flows toward the front up / down airflow direction flap 41.
- the air blown out from the second air passage 12 and the third air passage 13 is also bent forward by the rear upper / lower airflow direction flap 45 and guided to the front upper / lower airflow direction flap 41. For this reason, the angle of the air blown out from the blower outlet 3 can be adjusted by the control device 90 controlling the angle of the front side vertical wind direction flap 41.
- the control device 90 controls the angle of the front side vertical wind direction flap 41 as shown in FIG. Specifically, during cooling operation, the air blown out from the outlet 3 is heavier than the room air because it is colder than the room air. For this reason, the air blown out from the blower outlet 3 tends to flow downward. Therefore, in order to send the air blown out from the blower outlet 3 far into the room, the control device 90 puts the front side vertical wind direction flap 41 in a horizontal state in a side view. Thereby, the cold air which blows off from the blower outlet 3 can be sent far into the room.
- Embodiment 1 when the indoor unit 100 is in operation, the front end portion of the front vertical wind direction flap 41 is at the first air path 11 when the front vertical wind direction flap 41 is in a horizontal state at least in a side view. It is the structure located in front rather than. For this reason, since the air blown out from the first air passage 11 reliably hits the front vertical wind direction flap 41, the accuracy of angle control in the vertical direction of the air blown out from the blowout port 3 is improved. Moreover, in this Embodiment 1, the front side up-down wind direction flap 47 is rotated until the lower end part is located above the blower outlet 3, and the front-surface part of the casing 1 in the blower outlet 3 is fully opened.
- control device 90 can also control the angle of the front vertical wind direction flap 41 as shown in FIG. Specifically, the control device 90 controls the front side up / down wind direction flap when the remote controller 81 instructs to blow down, and when the infrared sensor 80 detects that the user is present near the indoor unit 100. 41 is in a vertical state in a side view. Thereby, the cold air which blows off from the blower outlet 3 can be sent to the indoor unit 100 vicinity.
- control device 90 can also stop the front side vertical wind direction flap 41 at an arbitrary angle between the state shown in FIG. 10 and the state shown in FIG. Further, for example, the control device 90 continuously changes the angle of the front vertical wind direction flap 41 at the angle between the state shown in FIG. 10 and the state shown in FIG. The angle can also be swing controlled.

なお、図4は、室内機100を右上方から見た図面であり、風路10の前面壁14及び正面側上下風向フラップ47を取り外した状態を示している。また、図5は、室内機100を右下方から見た図面であり、風路10の前面壁14及び正面側上下風向フラップ47を取り外した状態を示している。また、図6は、紙面左側が室内機100の正面側となっている。ここで、後述のように、本実施の形態1に係る室内機100においては、運転時、前側上下風向フラップ41が反転して用いられる構成となっている。つまり、図4及び図5は運転時における前側上下風向フラップ41の状態を示しており、図6は停止時における前側上下風向フラップ41の状態を示している。
そこで、本実施の形態1に係る室内機100においては、上下風向フラップ40及び左右風向フラップ50を以下のように構成している。
なお、正面側上下風向フラップ47は、後述のように暖房時の暖房性能をより向上させるものであり、上下風向フラップ40として必須の構成ではない。
ここで、板部材52が、本発明の第1板部材に相当する。
制御装置90は、専用のハードウェア、又はメモリに格納されるプログラムを実行するCPU(Central Processing Unit、中央処理装置、処理装置、演算装置、マイクロプロセッサ、マイクロコンピュータ、プロセッサともいう)で構成される。制御装置90は、例えばケーシング1における風路10以外の場所に収納されている。
続いて、このように構成された室内機100の動作について説明する。
図10~図13は、本実施の形態1に係る空気調和機の室内機における冷房運転動作を説明するための図である。なお、図10及び図11は、室内機100を右側から見た縦断面図である。また、図12は、風路10の前面壁14及び正面側上下風向フラップ47を取り外した状態の室内機100を示す正面図である。また、図13は、風路10の前面壁14及び正面側上下風向フラップ47を取り外した状態の室内機100を正面右側から見た斜視図である。
このように、第1左右風向フラップ51及び第2左右風向フラップ55を制御することで、吹出口3から左側に空気を吹き出すことができる。
冷房運転時と暖房運転時とで異なる点は、以下の2点である。
(1)風路10内に吸い込まれた室内空気は、室内熱交換器20を通る際、室内熱交換器20内を流れる冷媒によって加熱される点。
(2)正面側上下風向フラップ47の角度は、前側上下風向フラップ41の角度に応じて制御される点。
したがって、以下では、暖房運転時における前側上下風向フラップ41及び正面側上下風向フラップ47の制御方法について説明する。
実施の形態1では、第2左右風向フラップ55を前側上下風向フラップ41に設け、該前側上下風向フラップ41を回転させることにより、第2左右風向フラップ55を使用位置に配置する構造となっていた。これに限らず、第2左右風向フラップ55を使用位置に配置する構造を、例えば以下の様な構造にしてもよい。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、同一の機能や構成については同一の符号を用いて述べることとする。
複数の軸流ファン4をケーシング1の左右方向に並設する場合、以下のように室内機100を構成してもよい。なお、本実施の形態3において、特に記述しない項目については実施の形態1又は実施の形態2と同様とし、同一の機能や構成については同一の符号を用いて述べることとする。また、本実施の形態3では、説明の便宜上、右側に配置された軸流ファン4を軸流ファン4aと称し、左側に配置された軸流ファン4を軸流ファン4bと称する場合もある。
なお、図18及び図20は、風路10の前面壁14及び正面側上下風向フラップ47を取り外した状態を示している。
