However, there is a problem in that the center portion is bent and stable wind direction control cannot be obtained. On the other hand, in order to reduce the deflection of the central portion of the up / down airflow direction vanes, if it is attempted to shorten the distance between the pair of arm portions, the arm portions need to be disposed in the air outlet, which increases the blowing resistance. There existed a subject that ventilation performance fell.

The operation control unit also controls driving of the arm drive motor 34 and the blade drive motor 35.

次に、図3〜図7を用いて本実施の形態における空気調和機の動作を説明する。図3〜図7は、本実施の形態における空気調和機の送風動作を示す断面図である。   Next, operation | movement of the air conditioner in this Embodiment is demonstrated using FIGS. 3-7 is sectional drawing which shows the ventilation operation | movement of the air conditioner in this Embodiment.

図3は、空気調和機10の停止状態を示した図であり、パネル20、上下風向変更羽根30、及び中羽根40は全て閉塞した状態にある。   FIG. 3 is a diagram illustrating a stopped state of the air conditioner 10, and the panel 20, the up / down wind direction changing blade 30, and the middle blade 40 are all closed.

リモコン(図示せず)で空気調和機10の風向変更モードを上向方向(主に冷房運転時に)に設定して、空気調和機10の運転を開始すると、図4に示すように、パネル駆動機構21の動作によってパネル20は、吸込口5から前方に離間動作する。また同時に、腕部駆動用モータ34によって腕36が回動し、上下風向変更羽根30が吹出口6から前方に離間動作する。また上記パネル20の動作から少し遅延して、中羽根駆動用モータ41の動作によって、中羽根40の上端部40aが吸入口5から離間する方向に回動動作する。   When the air conditioner 10 wind direction change mode is set to the upward direction (mainly during cooling operation) with the remote controller (not shown) and the operation of the air conditioner 10 is started, as shown in FIG. The panel 20 moves forward away from the suction port 5 by the operation of the mechanism 21. At the same time, the arm 36 is rotated by the arm drive motor 34, and the up / down air direction changing blade 30 moves forward away from the outlet 6. Further, with a slight delay from the operation of the panel 20, the upper end portion 40 a of the middle blade 40 rotates in a direction away from the suction port 5 by the operation of the middle blade driving motor 41.

そして、図5に示すように、パネル20は、吸入口5から最も離間する位置まで動作するとともに、中羽根40の上端部40aがパネル20の下端と当接する位置まで動作する。一方、羽根駆動用モータ35によって上下風向変更羽根30が回動し、その下端部30aが吹出口6の最下流側端部の下部に当接する。そして、図5に示されるような状態で、熱交換器1で熱交換された空気が上向方向に吹き出される。   As shown in FIG. 5, the panel 20 operates to a position farthest from the suction port 5 and operates to a position where the upper end portion 40 a of the middle blade 40 contacts the lower end of the panel 20. On the other hand, the blade driving motor 35 rotates the up / down airflow direction changing blade 30, and the lower end 30 a abuts the lower end of the most downstream end of the air outlet 6. And the air heat-exchanged with the heat exchanger 1 is blown in the upward direction in the state as shown in FIG.

吹き出される空気は、上下風向変更羽根30の羽根形状に沿って、上向方向もしくは水平方向に送風され、居室の奥行き方向の遠くまで導かれるため、居室にいる人に直接冷風があたることを防ぐことができる。   The blown air is blown upward or horizontally along the blade shape of the up-and-down air direction changing blade 30 and guided to the far side in the depth direction of the room, so that the cold air is directly applied to the person in the room. Can be prevented.

尚、上記上向送風状態から停止状態への動作は、図5に示す上向送風状態から、図4に示す状態を経て、図3に示す停止状態に至るが、個々の動作は、停止状態から上向送風状態への動作と逆の動作であるため説明は省略する。   The operation from the upward air blowing state to the stop state is from the upward air blowing state shown in FIG. 5 to the stop state shown in FIG. 3 through the state shown in FIG. Since the operation is the reverse of the operation from the upward to the upward blowing state, the description thereof is omitted.

次に、下向送風状態に至る動作について説明する。   Next, the operation leading to the downward air blowing state will be described.

リモコンで空気調和機10の風向変更モードを下向方向(主に暖房運転時)に設定して運転を開始すると、図3に示す停止状態から、図6に示す状態へと動作するが、個々の動作は、上記上向送風と同様であるため説明は省略する。   When the operation is started by setting the air direction change mode of the air conditioner 10 to the downward direction (mainly during heating operation) with the remote controller, the operation is changed from the stop state shown in FIG. 3 to the state shown in FIG. Since the operation is the same as that of the upward air blowing, the description thereof is omitted.

図6に示す状態を経た後、図7に示すように、パネル駆動機構21の動作によってパネル20は、吸入口5から最も離間する位置まで動作する。一方、羽根駆動用モータ35によって上下風向変更羽根30が回動し、その上端部30bが吹出口6の下流側端部の上部に当接する。そして、図7に示す状態で、下向方向への送風が行われる。   After the state shown in FIG. 6, as shown in FIG. 7, the panel drive mechanism 21 moves the panel 20 to the position farthest from the inlet 5. On the other hand, the blade driving motor 35 rotates the up-and-down air direction changing blade 30, and the upper end 30 b abuts on the upper part of the downstream end of the outlet 6. And in the state shown in FIG. 7, ventilation is performed in the downward direction.

熱交換器1で熱交換されて吹き出される空気は、上下風向変更羽根30の羽根形状に沿って、居室の床面へ直下に導かれるため、居室にいる人に直接温風があたることを防ぐことができる。   The air blown out by heat exchange in the heat exchanger 1 is guided directly below the floor of the living room along the shape of the up-and-down air direction changing blades 30, so that hot air is directly applied to the person in the living room. Can be prevented.

尚、中羽根40は動作させても、動作させなくてもどちらでもかまわない。   The middle blade 40 may be operated or may not be operated.

下向送風状態から停止状態への動作は、図7に示す下向送風状態から、図6に示す状態を経て、図3に示す停止状態に至るが、個々の動作は、停止状態から下向送風状態への動作と逆の動作であるため説明は省略する。   The operation from the downward air blowing state to the stop state is from the downward air blowing state shown in FIG. 7 to the stop state shown in FIG. 3 through the state shown in FIG. 6, but each operation is downward from the stop state. Since the operation is the reverse of the operation to the blowing state, the description is omitted.

次に、斜め送風状態に至る動作について説明する。   Next, the operation leading to the oblique ventilation state will be described.

リモコンで空気調和機10の風向変更モードを斜め方向(冷房運転、暖房運転など)に設定して運転を開始すると、図3に示す停止状態から、図6に示す状態へと動作するが、個々の動作は上記上向送風と同様であるため説明は省略する。   When the operation is started by setting the air direction change mode of the air conditioner 10 to an oblique direction (cooling operation, heating operation, etc.) with the remote controller, the operation from the stop state shown in FIG. 3 to the state shown in FIG. Since the operation is the same as that of the upward air blowing, the description thereof is omitted.

次に、図6に示す状態を経た後、図8に示すように、パネル駆動機構21の動作によってパネル20は、吸入口5から最も離間する位置まで動作する。一方、羽根駆動用モータ35によって上下風向変更羽根30が回動し、斜め方向への送風状態となる。ここで、羽根駆動用モータ35によって、上下風向変更羽根30を所定角度でスイング動作させてもかまわない。また、中羽根40は動作させても、動作させなくてもどちらでもかまわない。   Next, after the state shown in FIG. 6, as shown in FIG. 8, the panel 20 moves to the position farthest from the suction port 5 by the operation of the panel drive mechanism 21. On the other hand, the blade driving motor 35 rotates the up-and-down air direction changing blade 30 so that the air is blown in an oblique direction. Here, the up / down wind direction changing blade 30 may be swung at a predetermined angle by the blade driving motor 35. Further, the middle blade 40 may be operated or may not be operated.

熱交換器1で熱交換されて吹き出される空気は、上下風向変更羽根30の羽根形状に沿って、居室の中央部へと導かれるため、居住にいる人に直接冷風もしくは温風をあてることができる。この送風状態は、主に冷房や暖房の運転開始時に用いられる。   The air blown out by heat exchange in the heat exchanger 1 is guided to the center of the living room along the blade shape of the up-and-down air direction changing blade 30, so that direct cold air or hot air is applied to people living in the room. Can do. This blowing state is mainly used at the start of cooling and heating operations.

斜め送風状態から停止状態への動作は、図8に示す斜め送風状態から、図6に示す状態を経て、図3に示す停止状態に至るが、個々の動作は、停止状態から斜め送風状態への動作と逆の動作であるため説明は省略する。   The operation from the oblique ventilation state to the stop state is from the oblique ventilation state shown in FIG. 8 to the stop state shown in FIG. 3 through the state shown in FIG. 6, but each operation is changed from the stop state to the oblique ventilation state. Since this operation is the reverse of the operation, the description is omitted.
