第１の腕部１４ａ、１４ｂ、上下風向変更羽根大１３と、第２の腕部２２ａ、２２ｂ、上下風向変更羽根小２１は、空気調和機１の停止時には、入れ子状に収納されている。 The first arm portions 14 a and 14 b, the up and down air direction changing blade large 13, the second arm portions 22 a and 22 b, and the up and down air direction changing blade small 21 are housed in a nested manner when the air conditioner 1 is stopped.

次に図３から図７を用いて動作を説明する。尚、図１は、空気調和機１の停止状態を示した図であり、パネル１１、上下風向変更羽根大１３および上下風向変更羽根小２１はすべて閉塞した状態にある。また、図３から図５の図中に示す二点鎖線は上下風向変更羽根大１３と上下風向変更羽根小２１との動作過程を表したものである。 Next, the operation will be described with reference to FIGS. FIG. 1 is a diagram showing a stopped state of the air conditioner 1, and the panel 11, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 are all closed. 3 to FIG. 5 represents the operation process of the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21.

リモコン（図示せず）により空気調和機１の風向変更モードを上向き方向（主に冷房運転）に設定して運転を開始すると、図３に示すように、パネル駆動装置１２の動作によってパネル１１は吸込口５から前方に最も離間した位置まで移動する。また同時に、駆動モータ１７によって第１の腕部１４ａ、１４ｂが吹出口６の下端近傍に配された軸１５を支点として下に回動し、上下風向変更羽根大１３が吹出口６から前方に離間して吹出口６が開口するよう所定の位置まで移動するとともに、駆動モータ１８の動作によって上下風向変更羽根大１３が第１の腕部１４ａ、１４ｂの先端側の回転中心２６を中心に回動し、その下端部が吹出口６の最下流側端部の下部に略当接する。 When the operation is started by setting the wind direction change mode of the air conditioner 1 to the upward direction (mainly cooling operation) by a remote controller (not shown), the panel 11 is moved by the operation of the panel drive device 12 as shown in FIG. It moves from the suction port 5 to the position farthest forward. At the same time, the drive motor 17 causes the first arm portions 14 a and 14 b to rotate downward with a shaft 15 disposed near the lower end of the air outlet 6 as a fulcrum, and the up and down airflow direction changing blade large 13 is moved forward from the air outlet 6. While moving away to a predetermined position so that the air outlet 6 is opened, the up / down airflow direction changing blade 13 is rotated around the rotation center 26 on the tip side of the first arm portions 14a, 14b by the operation of the drive motor 18. The lower end portion of the air outlet 6 substantially contacts the lower end of the most downstream end portion of the outlet 6.

一方、駆動モータ２５の動作によって、上下風向変更羽根小２１を羽根の凹形状が略下向となるように第２の腕部２２ａ、２２ｂの先端側の回転中心２６を中心に上向きに回動させるとともに、駆動モータ２４の回動によって第２の腕部２２ａ、２２ｂが吹出口６の下端近傍に配された軸２３を支点として動作し、上下風向変更羽根小２１を吹出口６の下流側上端部まで移動させ、その上部が吹出口６の最下流側端部の上部に略当接する。そして、この状態で上向き方向への送風が行われる。 On the other hand, by the operation of the drive motor 25, the up-and-down air direction changing blade small 21 is rotated upward about the rotation center 26 on the tip side of the second arm portions 22a and 22b so that the concave shape of the blade is substantially downward. In addition, the second arm portions 22a and 22b operate with the shaft 23 arranged near the lower end of the outlet 6 as a fulcrum by the rotation of the drive motor 24, and the upper and lower airflow direction changing blades 21 are arranged downstream of the outlet 6. It moves to an upper end part, The upper part substantially contact | abuts to the upper part of the most downstream end part of the blower outlet 6. FIG. In this state, the air is blown upward.

上下風向変更羽根１３、２１の移動時には、互いに衝突しないよう、上下風向変更羽根大１３は、上下風向変更羽根小２１の移動前に上下風向変更羽根小２１の軌跡外に移動させている。 The upper and lower airflow direction changing blade large 13 is moved out of the locus of the upper and lower airflow direction changing blades 21 before the upper and lower airflow direction changing blade small 21 is moved so that the upper and lower airflow direction changing blades 21 and 21 do not collide with each other.

従って、吹出グリル７で形成された送風通路９が送風方向へ延長され且つ送風路断面積が狭められることで、吹出口を出た瞬間の気流の拡散を防ぐことができ、気流は、上下風向変更羽根大１３の羽根形状に沿って上向き方向もしくは水平方向に送風されるため、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。 Accordingly, the air passage 9 formed by the blow grill 7 is extended in the air blowing direction and the air passage cross-sectional area is narrowed, so that the diffusion of the air flow at the moment of exiting the air outlet can be prevented. Since the air is blown in the upward direction or the horizontal direction along the blade shape of the changed blade size 13, it is possible to prevent the cold air from being directly applied to the person in the room.

また、図６（ｂ）に示すように、上下風向変更羽根大１３と上下風向変更羽根小２１とにより気流を縮流し、流速を増すことで居室の奥行き方向の遠くまで風を導くことが可能
となる。 In addition, as shown in FIG. 6 (b), it is possible to guide the wind to a distance in the depth direction of the room by constricting the air flow with the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 and increasing the flow velocity. It becomes.

尚、上向き送風状態から停止状態への動作は、上述した停止状態から上向き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。 Note that the operation from the upward blowing state to the stopped state is the reverse of the operation from the stopped state to the upward blowing state described above, and thus the description thereof is omitted.

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

リモコン（図示せず）により空気調和機１の風向変更モードを下向き方向（主に暖房運転）に設定して運転を開始すると、図４に示すように、パネル駆動装置１２の動作によってパネル１１は吸込口５から前方に最も離間した位置まで移動する。また同時に、駆動モータ１７によって第１の腕部１４ａ、１４ｂが軸１５を支点として下に回動し、上下風向変更羽根大１３が吹出口６から前方に離間して吹出口６が開口するよう図４の二点鎖線で示す所定の位置まで移動するとともに、駆動モータ１８の動作によって上下風向変更羽根大１３は回転中心２６を中心に同図中の二点鎖線の位置まで上向きに回動し、その上端部が吹出口６の最下流側端部の上部に略当接する。 When the wind direction change mode of the air conditioner 1 is set to a downward direction (mainly heating operation) by a remote controller (not shown) and the operation is started, the panel 11 is moved by the operation of the panel drive device 12 as shown in FIG. It moves from the suction port 5 to the position farthest forward. At the same time, the first arm portions 14 a and 14 b are rotated downward about the shaft 15 by the drive motor 17, so that the large vertical airflow direction changing blade 13 is spaced forward from the air outlet 6 so that the air outlet 6 opens. While moving to a predetermined position indicated by a two-dot chain line in FIG. 4, the up / down wind direction changing blade 13 is rotated upward about the rotation center 26 to the position of the two-dot chain line in FIG. The upper end of the upper end substantially contacts the uppermost end of the most downstream side of the outlet 6.

一方、駆動モータ２４によって第２の腕部２２ａ、２２ｂが軸２３を支点として下に回動し、上下風向変更羽根小２１を吹出口６の最下部まで移動させる。その後、上下風向変更羽根大１３が下向き送風状態の位置まで回動するとともに、その上端部が吹出口６の下流側端部の上部に略当接する位置まで第１の腕部１４ａ、１４ｂが動作する。また、上下風向変更羽根小２１は駆動モータ２５の動作によって、その下端部が吹出口６の最下流側端部の下部に略当接する位置まで回動する。そして、この状態で下向き方向への送風が行われる。 On the other hand, the second arm portions 22 a and 22 b are rotated downward about the shaft 23 by the drive motor 24, and the small vertical wind direction changing blade 21 is moved to the lowermost portion of the outlet 6. Thereafter, the upper and lower airflow direction changing blades 13 rotate to the position of the downward blowing state, and the first arm portions 14a and 14b operate to a position where the upper end portion is substantially in contact with the upper portion of the downstream end portion of the air outlet 6. To do. Further, the small up-and-down air direction changing vane 21 is rotated by the operation of the drive motor 25 to a position where the lower end portion thereof is substantially in contact with the lower end of the most downstream end portion of the outlet 6. In this state, air is blown in the downward direction.

上下風向変更羽根１３、２１の移動時には、互いに衝突しないよう、上下風向変更羽根大１３は、上下風向変更羽根小２１の移動前に上下風向変更羽根小２１の軌跡外に移動させている。具体的には、上下風向変更羽根大１３が吹出口６から前方に離間して吹出口６が開口するよう図４の二点鎖線で示す所定の位置まで移動すると、第２の腕部２２ａ、２２ｂが軸２３を支点として下に回動し始め、上下風向変更羽根小２１の回転中心２６が、上下風向変更羽根大１３の回転中心２６付近を通過するのと同期して、上下風向変更羽根大１３と上下風向変更羽根小２１が衝突しないように、双方の上下風向変更羽根１３、２１を移動させている。 The upper and lower airflow direction changing blade large 13 is moved out of the locus of the upper and lower airflow direction changing blades 21 before the upper and lower airflow direction changing blade small 21 is moved so that the upper and lower airflow direction changing blades 21 and 21 do not collide with each other. Specifically, when the up-and-down wind direction changing blade large 13 moves to a predetermined position indicated by a two-dot chain line in FIG. 4 so as to be spaced forward from the outlet 6 and the outlet 6 is opened, the second arm portion 22a, 22b begins to rotate downward with the shaft 23 as a fulcrum, and the vertical wind direction changing blade is synchronized with the rotation center 26 of the small vertical wind direction changing blade 21 passing through the vicinity of the rotational center 26 of the large vertical direction changing blade 13 Both the up / down air direction change blades 13 and 21 are moved so that the large 13 and the up / down air direction change blade small 21 do not collide.

従って、吹出グリル７で形成された送風通路９が送風方向へ延長され且つ送風路断面積が狭められることで、吹出口を出た瞬間の気流の拡散を防ぐことができ、気流は、上下風向変更羽根大１３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。 Accordingly, the air passage 9 formed by the blow grill 7 is extended in the air blowing direction and the cross section of the air passage is narrowed, so that the air current can be prevented from diffusing at the moment of exiting the air outlet. Since it is led directly to the floor surface of the living room along the blade shape of the changed blade size 13, it is possible to prevent the hot air from being directly applied to the person in the living room.

また、図６（ａ）に示すように、上下風向変更羽根大１３と上下風向変更羽根小２１とにより気流を縮流することができるため、暖房の即効性が向上する。 Moreover, as shown to Fig.6 (a), since an airflow can be shrunk by the up-and-down air direction change blade large 13 and the up-and-down air direction change blade small 21, the immediate effect of heating improves.

尚、下向き送風状態から停止状態への動作は、上述した停止状態から下向き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。 Note that the operation from the downward blowing state to the stopped state is the reverse of the operation from the stopped state to the downward blowing state described above, and a description thereof will be omitted.

次に、斜め方向への送風状態に至る動作について説明する。 Next, the operation leading to the blown state in the oblique direction will be described.

リモコン（図示せず）により空気調和機１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５に示すように、パネル駆動装置１２の動作によってパネル１１は吸込口５から前方に最も離間した位置まで移動する。また同時に、駆動モータ１７の回動によって第１の腕部１４ａ、１４ｂが軸１５を支点として下に回
動し、上下風向変更羽根大１３が吹出口６から前方に離間して吹出口６が開口するよう図５の二点鎖線で示す所定の位置まで移動するとともに、駆動モータ１８の動作によって上下風向変更羽根大１３は、吹出口６と衝突しない程度に回転中心２６を中心に同図中の二点鎖線の位置まで上向きに回動する。 When the wind direction change mode of the air conditioner 1 is set to an oblique direction (cooling operation, heating operation, etc.) by a remote controller (not shown) and the operation is started, as shown in FIG. 11 moves from the suction port 5 to the position farthest forward. At the same time, the first arm portions 14a and 14b are rotated downward about the shaft 15 by the rotation of the drive motor 17, and the large vertical airflow direction changing blade 13 is separated forward from the outlet 6 so that the outlet 6 is opened. While moving to a predetermined position indicated by a two-dot chain line in FIG. 5 so as to open, the up / down air direction changing blade large 13 is not shown in FIG. Rotate upward to the position of the two-dot chain line.

次に、駆動モータ２４の回動によって第２の腕部２２ａ、２２ｂが軸２３を支点として下に回動し、上下風向変更羽根小２１を吹出口６の下部まで移動させる。その後、上下風向変更羽根大１３が駆動モータ１８の動作によって斜め方向への送風状態となる位置まで回転中心２６を中心に回動するとともに、第１の腕部１４ａ，１４ｂの動作によって所定の位置まで移動し、送風路の略中央に位置する。また、上下風向変更羽根小２１は駆動モータ２５の動作によって、その下端部が吹出口６の最下流側端部の下部近傍に位置するまで回転中心２６を中心に回動し、斜め方向への送風状態となる位置まで移動する。ここで、駆動モータ１８および駆動モータ２５の回動によって、上下風向変更羽根大１３および上下風向変更羽根小２１を所定角度でスイング動作させてもかまわない。 Next, the second arm portions 22 a and 22 b are rotated downward with the shaft 23 as a fulcrum by the rotation of the drive motor 24, and the small vertical wind direction changing blade 21 is moved to the lower portion of the air outlet 6. Thereafter, the up / down wind direction changing blade 13 is rotated around the rotation center 26 to a position where the driving motor 18 is operated to be blown in an oblique direction, and at a predetermined position by the operation of the first arm portions 14a, 14b. And is located approximately in the center of the air passage. Further, the small up-and-down air direction changing blade 21 is rotated around the rotation center 26 until the lower end thereof is located near the lower end of the most downstream end of the air outlet 6 by the operation of the drive motor 25, and is inclined in the oblique direction. Move to the position where the air blows. Here, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 may be swung at a predetermined angle by the rotation of the driving motor 18 and the driving motor 25.

気流は、上下風向変更羽根大１３の羽根形状に沿って、居室の中央部へと導かれるため、居室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。 Since the airflow is guided to the center of the living room along the blade shape of the up-and-down airflow direction changing large blade 13, cold air or hot air can be directly applied to the person in the living room. This blowing state is mainly used at the start of cooling and heating operations.

また、図６（ｃ）に示すように、上下風向変更羽根大１３と上下風向変更羽根小２１とにより気流を縮流することができるため、気流の指向性向上と、冷房および暖房の即効性向上が図れる。 Moreover, as shown in FIG.6 (c), since an airflow can be shrunk by the up-and-down air direction change blade large 13 and the up-and-down air direction change blade small 21, the directivity improvement of airflow and the immediate effect of cooling and heating are possible. Improvement can be achieved.

尚、斜め送風状態から停止状態への動作は、上述した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。 Note that the operation from the oblique ventilation state to the stop state is the reverse of the above-described operation from the stop state to the oblique ventilation state, and thus the description thereof is omitted.

また、各送風状態間での移行動作も可能である。 Moreover, the transition operation | movement between each ventilation state is also possible.

上向き送風状態から下向き送風状態への移行は、先ず、図３に示す上下風向変更羽根小２１を図１に示す停止状態の位置へと回動させる。即ち、上下風向変更羽根小２１を回転中心２６を中心に下向きに吹出口６を閉塞する向きに回動させる。 In the transition from the upward air blowing state to the downward air blowing state, first, the vertical air direction changing blade small 21 shown in FIG. 3 is rotated to the position of the stop state shown in FIG. That is, the vertical airflow direction changing small blade 21 is rotated downward about the rotation center 26 in the direction of closing the air outlet 6.

次に、第１の腕部１４ａ、１４ｂを図４に示す二点鎖線の位置まで軸１５を支点として上向きに移動して、上下風向変更羽根大１３を回転中心２６を中心に上向きに吹出口６上部を閉塞し下部を開放する方向で凹部側が吹出口６の中央側となるように、同図中の二点鎖線で示す位置まで回動した後、第２の腕部２２ａ、２２ｂを軸２３を支点として動作して上下風向変更羽根小２１を吹出口６の最下部まで移動させる。その後、上下風向変更羽根大１３は下向き送風状態の位置まで、回転中心２６を中心に更に上向きに回動するとともに、その上端部が吹出口６の下流側端部の上部に略当接する位置まで第１の腕部１４ａ、１４ｂが軸１５を支点として上に動作する。また、上下風向変更羽根小２１は駆動モータ２５の動作によって、その下端部が吹出口６の最下流側端部の下部に略当接する位置まで回転中心２６を中心に上向きに回動する。 Next, the first arm portions 14a and 14b are moved upward with the shaft 15 as a fulcrum to the position of the two-dot chain line shown in FIG. 6 After rotating to the position indicated by the two-dot chain line in the drawing so that the concave portion side becomes the center side of the outlet 6 in the direction of closing the upper portion and opening the lower portion, the second arm portions 22a and 22b are pivoted. It operates using 23 as a fulcrum, and moves the small up-and-down airflow direction vane small 21 to the lowest part of the air outlet 6. Thereafter, the up / down air direction changing blade large 13 is rotated further upward about the rotation center 26 to the position of the downward blowing state, and the upper end of the large up / down air direction changing blade 13 is substantially in contact with the upper portion of the downstream end of the outlet 6. The first arm portions 14a and 14b move upward with the shaft 15 as a fulcrum. Further, the vertical wind direction changing blade small 21 is rotated upward about the rotation center 26 to a position where the lower end portion thereof is substantially in contact with the lower end of the most downstream end portion of the outlet 6 by the operation of the drive motor 25.

下向き送風状態から上向き送風状態への移行は、上述した上向き送風状態から下向き送風状態への移行動作の逆の動作であるため説明は省略する。 The transition from the downward blowing state to the upward blowing state is an operation reverse to the above-described transition operation from the upward blowing state to the downward blowing state.

上向き送風状態から斜め送風状態への移行は、先ず、図３に示す上下風向変更羽根小２１を図１に示す停止状態の位置へと回動させる。即ち、上下風向変更羽根小２１を回転中心２６を中心に下向きに吹出口６を閉塞する向きに回動させる。 In the transition from the upward air blowing state to the oblique air blowing state, first, the vertical air direction changing blade small 21 shown in FIG. 3 is rotated to the position of the stopped state shown in FIG. That is, the vertical airflow direction changing small blade 21 is rotated downward about the rotation center 26 in the direction of closing the air outlet 6.

次に、第１の腕部１４ａ、１４ｂを図５に示す二点鎖線の位置まで軸１５を支点として上向きに移動して、上下風向変更羽根大１３を回転中心２６を中心に凹部側が下向きとなる方向で上向きに、同図中の二点鎖線で示す位置まで回動した後、第２の腕部２２ａ、２２ｂを軸２３を支点として動作して上下風向変更羽根小２１を吹出口６の下部まで移動させる。その後、上下風向変更羽根大１３が斜め方向への送風状態となる位置まで回転中心２６を中心に上向きに回動させて、凹部側が下向きにするとともに、第１の腕部１４ａ，１４ｂの軸１５を支点とした上向きの動作によって所定の位置まで移動し、送風路の略中央に位置させる。また、上下風向変更羽根小２１は駆動モータ２５の動作によって、その下端部が吹出口６の最下流側端部の下部近傍に位置するまで回転中心２６を中心に回動し、斜め方向への送風状態となる位置まで回動する。 Next, the first arm portions 14a and 14b are moved upward with the shaft 15 as a fulcrum to the position of the two-dot chain line shown in FIG. The second arm portions 22a and 22b are operated with the shaft 23 as a fulcrum, and the up / down air direction change vane small 21 is moved to the outlet 6 by turning upward in the direction to the position indicated by the two-dot chain line in FIG. Move to the bottom. Thereafter, the upper and lower wind direction changing blades 13 are rotated upward around the rotation center 26 to a position where the blades 13 are in a slanting direction, the concave side is directed downward, and the shafts 15 of the first arm portions 14a and 14b. Is moved to a predetermined position by an upward operation with fulcrum as a fulcrum, and is positioned at the approximate center of the air passage. Further, the small up-and-down air direction changing blade 21 is rotated around the rotation center 26 until the lower end thereof is located near the lower end of the most downstream end of the air outlet 6 by the operation of the drive motor 25, and is inclined in the oblique direction. It rotates to the position where it becomes a blowing state.

斜め送風状態から上向き送風状態への移行は、上述した上向き送風状態から斜め送風状態への移行動作の逆の動作となるため説明は省略する。 Since the transition from the oblique air blowing state to the upward air blowing state is the reverse operation of the above-described transition operation from the upward air blowing state to the oblique air blowing state, the description thereof is omitted.

下向き送風状態から斜め送風状態への移行は、図４に示す上下風向変更羽根大１３を図５に示す斜め方向への送風位置へと回動するとともに、図４に示す第２の腕部２２ａ、２２ｂを動作させて図５に示す位置まで移動した後、上下風向変更羽根小２１を斜め方向への送風位置へと回動させる。即ち、上下風向変更羽根大１３を回転中心２６を中心に上向きに、閉塞していた吹出口６上部を開放する方向で回動して送風路の略中央に位置させるとともに、第２の腕部２２ａ、２２ｂを軸２３を支点として上向きに動作させつつ上下風向変更羽根小２１を回転中心２６を中心に上向きに回動させ、上下風向変更羽根大１３と略平行となるよう位置させる。 In the transition from the downward blowing state to the oblique blowing state, the upper and lower air direction changing blades 13 shown in FIG. 4 are rotated to the blowing position in the oblique direction shown in FIG. 5 and the second arm portion 22a shown in FIG. , 22b is operated and moved to the position shown in FIG. 5, and then the up / down air direction changing blade small 21 is rotated to the blowing position in the oblique direction. That is, the upper and lower airflow direction changing blades 13 are rotated upward about the rotation center 26 and are rotated in the direction of opening the upper part of the closed outlet 6 so as to be positioned substantially at the center of the air passage, and the second arm portion. The small vertical airflow direction change blades 21 are rotated upward about the rotation center 26 while operating the shafts 23a and 22b upward with the shaft 23 as a fulcrum so as to be positioned substantially parallel to the large vertical airflow direction change blades 13.

斜め送風状態から下向き送風状態への移行は、上述した下向き送風状態から斜め送風状態への移行動作と逆の動作となるため説明は省略する。 Since the transition from the oblique ventilation state to the downward ventilation state is an operation reverse to the above-described transition operation from the downward ventilation state to the oblique ventilation state, the description thereof is omitted.

さらに、本実施の形態１の構成においては、上下風向変更羽根大１３と上下風向変更羽根小２１とは互いに独立して回転動作するとともに、上下位置を入れ替えることが可能であるため、動作の説明は省略するが、図６（ｅ）および（ｆ）に示すように、吹き出す空気を２層の気流にしたり、図６（ｇ）に示すように、吹き出す空気を２方向に分流させることも可能であるため、多様な風向制御が実現できる。 Furthermore, in the configuration of the first embodiment, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 rotate independently of each other and can be interchanged in the up / down position. Is omitted, but as shown in FIGS. 6 (e) and (f), the air to be blown can be divided into two layers, or the air to be blown can be divided into two directions as shown in FIG. 6 (g). Therefore, various wind direction control can be realized.

ここで、図１３と図１４を用いて左右方向への送風状態について説明する。 Here, the air blowing state in the left-right direction will be described with reference to FIGS. 13 and 14.

図１３（ａ）は本発明の空気調和機１の下向き送風状態を示した断面図であり、図１３（ｂ）は本発明の空気調和機１の向かって右方向への送風状態を示した平面図である。また、図１４（ａ）は従来例の空気調和機１の下向き送風状態を示した断面図であり、図１４（ｂ）は従来例の空気調和機１の向かって右方向への送風状態を示した平面図である。尚、図中の矢印は吹き出す空気の流れを表したものである。 FIG. 13A is a cross-sectional view showing a downward blowing state of the air conditioner 1 of the present invention, and FIG. 13B shows a rightward blowing state of the air conditioner 1 of the present invention. It is a top view. 14A is a cross-sectional view showing a downward blowing state of the air conditioner 1 of the conventional example, and FIG. 14B shows a blowing state of the right direction toward the air conditioner 1 of the conventional example. It is the shown top view. In addition, the arrow in a figure represents the flow of the air to blow off.

左右方向へ吹き出す空気の風向変更は、吹出口６の上流側に備えた複数の左右風向変更羽根８により行う。しかしながら、従来例の空気調和機においては、図１４（ａ）および図１４（ｂ）に示すように、上下風向変更羽根１３が１枚構成であるため気流が吹出口６を出た瞬間に拡散してしまう。このため吹き出す空気を左右風向変更羽根８で風向変更しても、意図する所定の最大角度まで曲げることができなかった。 The change of the air direction of the air blown out in the left and right direction is performed by a plurality of left and right air direction changing blades 8 provided on the upstream side of the air outlet 6. However, in the conventional air conditioner, as shown in FIGS. 14 (a) and 14 (b), the airflow diffuses at the moment when the airflow exits from the outlet 6 because the up-and-down airflow direction changing blade 13 is composed of one sheet. Resulting in. For this reason, even if the wind direction is changed by the left and right wind direction changing blades 8, it cannot be bent to the intended predetermined maximum angle.

そこで、本発明の構成においては、図１３（ａ）および図１３（ｂ）に示すように、上下風向変更羽根小２１で気流の拡散を防ぐことができるため、所定の最大角度まで気流を曲げることが可能となり、居室の左右方向への送風範囲を拡大することができる。 Therefore, in the configuration of the present invention, as shown in FIGS. 13 (a) and 13 (b), since the diffusion of the airflow can be prevented with the small up and down airflow direction changing blades 21, the airflow is bent to a predetermined maximum angle. It becomes possible, and the ventilation range to the left-right direction of a living room can be expanded.

次に、上述した構成について、図７を用いて補足説明する。図７は、同空気調和機の上下風向変更羽根小の動作を示した拡大断面図で、（ａ）は回転中心を羽根端部に配設した場合、（ｂ）は回転中心を羽根中央部に配設した場合を示している。 Next, the above-described configuration will be supplementarily described with reference to FIG. FIG. 7 is an enlarged cross-sectional view showing the operation of the small up and down air direction change blades of the air conditioner, where (a) shows the center of rotation at the blade end, and (b) shows the center of rotation at the center of the blade. The case where it arrange | positions is shown.

例えば、図７（ｂ）に示すように、上下風向変更羽根小２１を吹出口６の中央部に設け、回転中心２６を上下風向変更羽根小２１の中央部に配設した場合、各送風モードにおける上下風向変更羽根小２１の回転中心２６の軌跡３０は一点鎖線で示したように不規則となるため、各送風モードへの移行時に上下風向変更羽根小２１を保持して駆動する第２の腕部２２ａ、２２ｂは上下と左右との２方向動作が必要となる。このため、第２の腕部２２ａ、２２ｂは２軸で構成しなければならず、構造が複雑となり部品点数が増加してしまうことになる。 For example, as shown in FIG. 7 (b), when the up / down air direction changing vane small 21 is provided in the central portion of the outlet 6 and the rotation center 26 is provided in the central portion of the up / down air direction changing vane small 21, Since the trajectory 30 of the rotation center 26 of the up / down air direction change blade small 21 is irregular as shown by the alternate long and short dash line, the second up / down air direction change blade small 21 is held and driven at the time of transition to each blowing mode. The arm portions 22a and 22b need to move in two directions, up and down and left and right. For this reason, the second arm portions 22a and 22b must be configured with two axes, and the structure becomes complicated and the number of parts increases.

（実施の形態２）
図８は、本発明の第２の実施の形態における空気調和機の断面図である。 (Embodiment 2)
FIG. 8 is a cross-sectional view of an air conditioner according to the second embodiment of the present invention.

以下の説明において、第１の実施の形態の説明と重複する空気調和機１の構成および動作に関する説明は省略する。 In the following description, a description of the configuration and operation of the air conditioner 1 that overlaps the description of the first embodiment will be omitted.

図８に示すように、上下風向変更羽根大１３、上下風向変更羽根小２１は共に断面が弓形で、図８で示される空気調和機１の停止時には、凹部が上流側となるように、上下風向変更羽根大１３を前面側に、上下風向変更羽根大１３の背面側に上下風向変更羽根小２１を備えている。 As shown in FIG. 8, both the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 have an arcuate cross section, and when the air conditioner 1 shown in FIG. The large wind direction changing blade 13 is provided on the front side, and the small up and down air direction changing blade 21 is provided on the back side of the up and down air direction changing blade large 13.

On the back side of the large blade 13, it is arranged in the outlet 6 so as to be hidden by the large vertical airflow direction changing blade 13.

第１の実施の形態と同様に、上下風向変更羽根大１３は吹出口６の左右開口端部に設けた一対の第１の腕部１４ａ、１４ｂにより回動自在に保持されており、第１の腕部１４ａには上下風向変更羽根大１３を、第１の腕部１４ａ、１４ｂの作用点側即ち先端側に配設された回転中心２６を中心に回転動作させる駆動モータ１８が備えられている。また、第１の腕部１４ｂは歯車１６を介して駆動モータ１７に連結され、第１の腕部１４ａが１４ｂと連動するように軸１５が備えられ、駆動モータ１７により第１の腕部１４ａと１４ｂとを、吹出口６の下端近傍に配された軸１５を支点として動作させている。第１の腕部１４ａと１４ｂは互いに左右対称で、上下風向変更羽根大１３が捩れたりしないよう並行に動作する。 Similar to the first embodiment, the up-and-down air direction changing blade large 13 is rotatably held by a pair of first arm portions 14a and 14b provided at the left and right opening ends of the air outlet 6. The arm portion 14a is provided with a drive motor 18 for rotating the large up-and-down wind direction changing blade 13 around a rotation center 26 arranged on the action point side, that is, the tip side of the first arm portions 14a and 14b. Yes. The first arm portion 14b is connected to the drive motor 17 via the gear 16, and a shaft 15 is provided so that the first arm portion 14a is interlocked with 14b. The drive motor 17 causes the first arm portion 14a to be linked. And 14b are operated with a shaft 15 disposed in the vicinity of the lower end of the outlet 6 as a fulcrum. The first arm portions 14a and 14b are symmetrical with each other, and operate in parallel so that the up-and-down wind direction changing blade size 13 is not twisted.

上下風向変更羽根小２１は上下風向変更羽根大１３の背面側に配置され、上下風向変更羽根小２１の背面側に設けた回転中心２６を上下風向変更羽根大１３の凹面側に設けた支柱３１で回動自在に保持されている。また、支柱３１には駆動モータ２５が備えられ、駆動モータ２５は回転中心２６に連結しており、駆動モータ２５の動作により上下風向変更羽根小２１は、後述する各送風状態において最適な位置に配置されるように回動する。尚、支柱３１は、第１の実施の形態で述べた第１の腕部１４ａおよび１４ｂの内側に複数設けたもので、上下風向変更羽根小２１が捩れたりしないよう並行に動作する。 The up / down air direction change vane small 21 is arranged on the back side of the up / down air direction change vane large 13, and the column 31 provided with the rotation center 26 provided on the back side of the up / down air direction change vane small 21 on the concave side. Is held rotatably. Further, the support 31 is provided with a drive motor 25, and the drive motor 25 is connected to the rotation center 26, and the operation of the drive motor 25 causes the up / down wind direction changing blade small 21 to be in an optimal position in each air blowing state described later. Rotate to be placed. In addition, the support | pillar 31 is provided with two or more inside the 1st arm parts 14a and 14b described in 1st Embodiment, and operate | moves in parallel so that the up-and-down wind direction change blade | wing small 21 may not twist.

次に図９を用いて動作を説明するが、パネル１１の動作については、第１の実施の形態と同じであるため説明を省略する。また、図中に示す二点鎖線は上下風向変更羽根小２１の動作過程を示したものである。 Next, the operation will be described with reference to FIG. 9. Since the operation of the panel 11 is the same as that of the first embodiment, the description thereof will be omitted. In addition, a two-dot chain line shown in the figure shows an operation process of the up / down wind direction changing blade small 21.

第１の実施の形態と同様に、空気調和機１の風向変更モードを上向き方向（主に冷房運転）に設定して運転を開始すると、パネル１１が吸込口５から前方に最も離間した位置まで移動し、図９（ａ）に示すように、駆動モータ１７によって第１の腕部１４ａ、１４ｂが吹出口６の下端近傍に配された軸１５を支点として下に回動し、上下風向変更羽根大１３が吹出口６から前方に離間して吹出口６が開口するよう所定の位置まで移動するとともに、駆動モータ１８の動作によって上下風向変更羽根大１３が第１の腕部１４ａ、１４ｂの先端側の回転中心２６を中心に回動し、その下端部が吹出口６の最下流側端部の下部に略当接する。 As in the first embodiment, when the air direction change mode of the air conditioner 1 is set to the upward direction (mainly cooling operation) and the operation is started, the panel 11 reaches the position farthest away from the suction port 5 forward. As shown in FIG. 9 (a), the first arm portions 14a and 14b are rotated downward by the drive motor 17 with the shaft 15 disposed in the vicinity of the lower end of the outlet 6 as a fulcrum, and the vertical wind direction is changed. The large blade 13 moves to a predetermined position so that the large outlet 13 is spaced forward from the outlet 6 and the outlet 6 is opened, and the up and down airflow direction changing large blade 13 is moved by the operation of the drive motor 18 to the first arm portions 14a, 14b. It rotates around the rotation center 26 on the front end side, and its lower end is substantially in contact with the lower part of the most downstream end of the outlet 6.

それに伴って上下風向変更羽根大１３の凹面側に連設された支柱３１及び支柱３１で保持されている上下風向変更羽根小２１も吹出口６から前方に離間する方向に移動する。 Along with this, the column 31 continuously provided on the concave side of the up / down air direction changing blade large 13 and the small up / down air direction changing blade 21 held by the column 31 also move in the direction away from the outlet 6 in the forward direction.

その後、駆動モータ２５の動作によって、上下風向変更羽根小２１を羽根の凹形状が略下向となるように支柱３１の回転中心２６を中心に上向きに回動させ、その上部が吹出口６の最下流側端部の上部に略当接させる。そして、この状態で上向き方向への送風が行われる。 Thereafter, by the operation of the drive motor 25, the up / down air direction changing blade small 21 is rotated upward about the rotation center 26 of the support column 31 so that the concave shape of the blade is substantially downward, and the upper portion of the small outlet 21 is the air outlet 6. It is made to substantially contact | abut to the upper part of a downstream end part. In this state, the air is blown upward.

上下風向変更羽根１３、２１の移動時には、互いに衝突しないよう、上下風向変更羽根
大１３は、上下風向変更羽根小２１の移動前に上下風向変更羽根小２１の軌跡外に移動させている。 The upper and lower airflow direction changing blade large 13 is moved out of the locus of the upper and lower airflow direction changing blades 21 before the upper and lower airflow direction changing blade small 21 is moved so that the upper and lower airflow direction changing blades 21 and 21 do not collide with each other.

ここで、上下風向変更羽根大１３の下端部が吹出口６の最下流側端部の下部に、上下風向変更羽根小２１の上部が吹出口６の最下流側端部の上部にそれぞれ略当接するように、上下風向変更羽根大１３、上下風向変更羽根小２１、支柱３１等の形状が定められている。即ち、上下風向変更羽根大１３の羽根部から支柱３１の回転中心２６までの長さと、支柱３１の回転中心２６から上下風向変更羽根小２１の羽根部までの長さとの和が、吹出口６の開口部上下端間の長さとほぼ同じとなるように形状が定められる。 Here, the lower end portion of the up / down airflow direction changing large blade 13 is substantially below the lowermost end portion of the blower outlet 6, and the upper portion of the up / down airflow direction changing blade small portion 21 is substantially above the uppermost end portion of the blowout outlet 6. The shapes of the up-and-down air direction changing blade large 13, the up-and-down air direction changing blade small 21, the support column 31 and the like are determined so as to come into contact with each other. That is, the sum of the length from the blade portion of the up / down air direction changing blade large 13 to the rotation center 26 of the support column 31 and the length from the rotation center 26 of the support column 31 to the blade portion of the up / down air direction changing blade small 21 is the outlet 6. The shape is determined to be substantially the same as the length between the upper and lower ends of the opening.

以上のように、吹出グリル７で形成された送風通路９が送風方向へ延長され且つ送風路断面積が狭められることで、吹出口を出た瞬間の気流の拡散を防ぐことができ、気流は、上下風向変更羽根大１３の羽根形状に沿って上向き方向もしくは水平方向に送風されるため、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。 As described above, the air passage 9 formed by the blow-out grill 7 is extended in the air blowing direction and the cross-sectional area of the air passage is narrowed, so that the diffusion of the air flow at the moment of exiting the air outlet can be prevented. Since the air is blown upward or horizontally along the blade shape of the large vertical airflow direction change blade 13, it is possible to prevent the cold air from being directly applied to the person in the room.

また、上下風向変更羽根大１３と上下風向変更羽根小２１により気流を縮流し、流速を増すことで居室の奥行き方向の遠くまで風を導くことが可能となる。 Further, the air flow is reduced by the up / down air direction change vane large 13 and the up / down air direction change vane small 21 and the flow velocity can be increased to guide the wind far to the depth direction of the living room.

空気調和機１の風向変更モードを下向き方向（主に暖房運転）に設定して運転を開始すると、パネル１１が吸込口５から前方に最も離間した位置まで移動し、図９（ｂ）に示すように、駆動モータ１７によって第１の腕部１４ａ、１４ｂが軸１５を支点として下に回動し、上下風向変更羽根大１３が吹出口６から前方に離間して吹出口６が開口するよう所定の位置まで移動し、上下風向変更羽根１３の回動によりその上端部が吹出口６の最下流側上端部と干渉しない位置まで移動した後、駆動モータ１８の動作によって上下風向変更羽根大１３が回転中心２６を中心に下向き送風状態の位置まで上向きに回動するとともに、その上端部が吹出口６の下流側端部の上部に略当接する位置まで第１の腕部１４ａ、１４ｂが動作する。 When the wind direction change mode of the air conditioner 1 is set to the downward direction (mainly heating operation) and the operation is started, the panel 11 moves to the position farthest away from the suction port 5 and is shown in FIG. 9B. As described above, the first arm portions 14a and 14b are rotated downward about the shaft 15 by the drive motor 17, so that the up / down airflow direction changing blade 13 is spaced forward from the outlet 6 and the outlet 6 is opened. After moving to a predetermined position, the upper and lower airflow direction changing blades 13 are moved to a position where the upper end portion thereof does not interfere with the uppermost downstream side upper edge portion of the outlet 6, and then the upper and lower airflow direction changing blades 13 are moved by the operation of the drive motor 18. Is rotated upward about the rotation center 26 to the position of the air blowing state, and the first arm portions 14a and 14b operate to a position where the upper end portion thereof is substantially in contact with the upper portion of the downstream end portion of the air outlet 6. To do.

それに伴って上下風向変更羽根大１３に連設された支柱３１及び支柱３１で保持されている上下風向変更羽根小２１も吹出口６から前方に離間する方向に、同図中の二点鎖線の位置まで移動する。 Along with this, the support 31 connected to the up / down air direction change blade large 13 and the up / down air direction change blade small 21 held by the support 31 also move forwardly away from the outlet 6 in the direction of the two-dot chain line in FIG. Move to position.

その後、駆動モータ２５の動作によって上下風向変更羽根小２１が回転中心２６を中心に下向きに回動し、その下端部が吹出口６の最下流側端部の下部に略当接する。そして、この状態で下向き方向への送風が行われる。 Thereafter, the up-and-down wind direction changing blade 21 is rotated downward about the rotation center 26 by the operation of the drive motor 25, and the lower end portion thereof substantially contacts the lower portion of the most downstream end portion of the air outlet 6. In this state, air is blown in the downward direction.

従って、吹出グリル７で形成された送風通路９が送風方向へ延長され且つ送風路断面積が狭められることで、吹出口を出た瞬間の気流の拡散を防ぐことができ、気流は、上下風向変更羽根大１３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。 Accordingly, the air passage 9 formed by the blow grill 7 is extended in the air blowing direction and the air passage cross-sectional area is narrowed, so that the diffusion of the air flow at the moment of exiting the air outlet can be prevented. Since it is led directly to the floor surface of the living room along the blade shape of the changed blade size 13, it is possible to prevent the hot air from being directly applied to the person in the living room.

また、上下風向変更羽根大１３と上下風向変更羽根小２１により気流を縮流することができるため、暖房の即効性が向上する。 Moreover, since the air flow can be reduced by the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21, the immediate effect of heating is improved.

尚、下向き送風状態から停止状態への動作は、上述した停止状態から下向き送風状態へ
の動作と逆の動作であるため説明は省略する。 Note that the operation from the downward blowing state to the stopped state is the reverse of the operation from the stopped state to the downward blowing state described above, and a description thereof will be omitted.

空気調和機１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、パネル１１は吸込口５から前方に最も離間した位置まで移動し、図９（ｃ）に示すように、駆動モータ１７によって第１の腕部１４ａ、１４ｂが軸１５を支点として下に回動し、上下風向変更羽根大１３が吹出口６から前方に離間して吹出口６が開口するよう所定の位置まで移動し、上下風向変更羽根１３の回動によりその上端部が吹出口６の最下流側上端部と干渉しない位置まで移動した後、駆動モータ１８の動作によって上下風向変更羽根大１３が斜め方向への送風状態となる位置まで回転中心２６を中心に回動するとともに、上下風向変更羽根大１３が送風通路９及び吹出口６からの送風の流路方向と略平行且つ吹出口６開口部の中間部でその上下面を送風が通過する位置まで第１の腕部１４ａ、１４ｂが動作する。 When the air direction change mode of the air conditioner 1 is set to an oblique direction (cooling operation, heating operation, etc.) and the operation is started, the panel 11 moves from the suction port 5 to the position farthest forward, and FIG. 9 (c). 1, the first arm portions 14 a and 14 b are rotated downward about the shaft 15 by the drive motor 17, and the large vertical airflow direction changing blade 13 is spaced forward from the air outlet 6 to open the air outlet 6. The upper and lower wind direction changing blades 13 are moved to a predetermined position so that the upper end moves to a position where the uppermost downstream side of the blower outlet 6 does not interfere with the upper and lower wind direction changing blades. The upper and lower airflow direction changing blades 13 are substantially parallel to the airflow direction of the airflow from the airflow passage 9 and the air outlet 6 and are blown to the position where the main airflow 13 is inclined to the position where the airflow is in the oblique direction. Inside the exit 6 opening The first arm portion 14a of the upper and lower surfaces thereof in parts to a position where the blower passes, 14b is operated.

その後、駆動モータ２５の動作によって、上下風向変更羽根小２１は回転中心２６を中心に下向きに回動し、送風通路９及び吹出口６からの送風の流路方向と略平行となる位置まで移動する。そして、この状態で斜め方向への送風が行われる。ここで、駆動モータ１８および駆動モータ２５の回動によって、上下風向変更羽根大１３および上下風向変更羽根小２１を所定角度でスイング動作させてもかまわない。 Thereafter, by the operation of the drive motor 25, the up-and-down air direction changing blade small 21 rotates downward about the rotation center 26 and moves to a position that is substantially parallel to the direction of the air flow from the air passage 9 and the air outlet 6. To do. In this state, air is blown in an oblique direction. Here, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 may be swung at a predetermined angle by the rotation of the driving motor 18 and the driving motor 25.

従って、吹出グリル７で形成された送風通路９が送風方向へ延長されることで、吹出口を出た瞬間の気流の拡散を防ぐことができ、気流は、上下風向変更羽根大１３の羽根形状に沿って、居室の中央部へと導かれるため、居室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。 Therefore, the air passage 9 formed by the blow grill 7 is extended in the blow direction, so that the air current can be prevented from diffusing at the moment of exiting the air outlet. Therefore, cold air or hot air can be directly applied to the person in the room. This blowing state is mainly used at the start of cooling and heating operations.

また、上下風向変更羽根大１３と上下風向変更羽根小２１により気流を縮流することができるため、気流の指向性向上と、冷房および暖房の即効性向上が図れる。 In addition, since the air flow can be reduced by the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21, it is possible to improve the directivity of the air flow and the immediate effect of cooling and heating.

また、動作の説明は省略するが、各送風状態間での移行動作も可能である。 Moreover, although description of operation | movement is abbreviate | omitted, the transfer operation | movement between each ventilation state is also possible.

さらに、本実施の形態の構成においては、上下風向変更羽根大１３と上下風向変更羽根小２１とが互いに独立して回転動作するため、第１の実施の形態で説明したように、吹き出す空気を２層の気流にしたり、２方向に分流させることも可能であるため、多様な風向制御が実現できる。 Furthermore, in the configuration of the present embodiment, the up / down air direction changing blade large 13 and the up / down air direction changing blade small 21 rotate independently of each other, and therefore, as described in the first embodiment, the air blown out is blown out. Since it is possible to make a two-layer airflow or to divert in two directions, various wind direction controls can be realized.

また、第１の実施の形態で述べたように、上下風向変更羽根小２１で気流の拡散を防ぐことができるため、所定の最大角度まで気流を曲げることが可能となり、居室の左右方向への送風範囲を拡大することができる。 In addition, as described in the first embodiment, since the diffusion of the airflow can be prevented with the small up and down airflow direction changing blades 21, it is possible to bend the airflow to a predetermined maximum angle, The blowing range can be expanded.

以上のように、本実施の形態においては、吹出口６に、互いに独立して回動動作する共に弓形の上下風向変更羽根大１３と上下風向変更羽根小２１の２枚の羽根を備え、吹出口６に上下風向変更羽根大１３を回動自在に保持する変動自在な一対の第１の腕部１４ａ、
１４ｂを設け、上下風向変更羽根大１３の凹面側に設けた支柱３１で上下風向変更羽根小２１を回動自在に保持し、空気調和機停止時には、上下風向変更羽根小２１を上下風向変更羽根大１３の背面側で且つ支柱３１に設けた回転中心２６の前面側に、上下風向変更羽根小２１の凹形状が上下風向変更羽根大１３と同一方向となるように配設して、上下風向変更羽根大１３、小２１は上下位置入れ替えが可能で、且つ回動によって対向する面をも入れ替え可能で、吹出口の開口部上下端近傍で凹部が互いに対向し、上下風向変更羽根大１３は吹き出される空気を上方および下方に曲げるとき気流の外側に位置し、上下風向変更羽根小２１は吹き出される空気を上方および下方に曲げるとき気流の内側に位置するように配設可能であるため、多様な風向制御が行えるとともに、左右方向への風の吹出し角度の拡大および居室の遠方まで風を導くことが可能となる。 As described above, in the present embodiment, the air outlet 6 is provided with two blades of the large up-and-down air direction changing blade 13 and the up and down air direction changing blade small 21 that rotate independently of each other. A pair of variable first arms 14a for holding the up-and-down wind direction changing blade large 13 at the outlet 6 in a rotatable manner;
14b, and the vertical wind direction change blade small 21 is rotatably held by the support column 31 provided on the concave surface side of the large vertical wind direction change blade 13. When the air conditioner is stopped, the vertical wind direction change blade small 21 is moved to the vertical wind direction change blade 21. On the back side of the large 13 and on the front side of the center of rotation 26 provided on the support column 31, the concave shape of the small vertical wind direction changing blades 21 is arranged in the same direction as the large vertical wind direction changing blades 13. The change blade large 13 and the small blade 21 can be switched in the vertical position, and the surfaces facing each other can also be switched by rotation. The recesses face each other in the vicinity of the upper and lower ends of the opening of the air outlet. When the blown air is bent upward and downward, it is positioned outside the airflow, and the up / down airflow direction changing small blade 21 can be disposed so as to be positioned inside the airflow when bending the blown air upward and downward. Many Wind direction control with enabling such, it is possible to guide the air longer distance expansion and room for blowing angle of the wind in the lateral direction.

FIG. 10 is a cross-sectional view of an air conditioner according to a third embodiment of the present invention, FIG. 11 is a structural diagram of the up-and-down air direction changing blades of the air conditioner, and FIG. 12 shows an operating state of the air conditioner. FIG.

以下の説明において、第１および２の実施の形態の説明と重複する空気調和機１の構成および動作に関する説明は省略する。 In the following description, a description of the configuration and operation of the air conditioner 1 that overlaps the description of the first and second embodiments will be omitted.

図１０に示すように、吹出口６の下流側上下端部にそれぞれ回転中心２６を持つ２枚の上下風向変更羽根４０，４１は共に断面が弓形で、図１０で示される空気調和機１の停止時には、共に凹部が上流側となり、上下風向変更羽根４０が吹出口６の開口部上部を、上下風向変更羽根４１が吹出口６の開口部下部を、それぞれ閉塞するように配置されている。２枚の上下風向変更羽根４０，４１の回転中心２６と反対側の縁部同士は近接し、全体として吹出口６が閉塞される。即ち、２枚の上下風向変更羽根４０，４１を合わせた全長と吹出口６の開口部上下長とがほぼ同じ大きさとなる。尚、本実施例では、上下風向変更羽根４０，４１は同形状であるが、大きさが異なってもよい。 As shown in FIG. 10, the two upper and lower airflow direction changing blades 40 and 41 each having a rotation center 26 at the upper and lower ends on the downstream side of the air outlet 6 are both arcuate in cross section, and the air conditioner 1 shown in FIG. At the time of stopping, both the concave portions are on the upstream side, and the upper and lower wind direction changing blades 40 are arranged so as to block the upper part of the opening of the blower outlet 6, and the upper and lower wind direction changing blades 41 are closed. The edges on the opposite side of the rotation center 26 of the two vertical airflow direction changing blades 40 and 41 are close to each other, and the air outlet 6 is closed as a whole. That is, the total length of the two upper and lower airflow direction changing blades 40 and 41 and the upper and lower length of the opening of the air outlet 6 are substantially the same. In the present embodiment, the up / down wind direction changing blades 40 and 41 have the same shape, but the sizes may be different.

また、回転中心２６には駆動モータ４２、４３がそれぞれ連結されており、駆動モータ４２，４３の動作により、上下風向変更羽根４０および４１をそれぞれ上方向、下方向へ回動させる。 Further, drive motors 42 and 43 are connected to the rotation center 26, and the operation of the drive motors 42 and 43 causes the up and down air direction changing blades 40 and 41 to rotate upward and downward, respectively.

上下風向変更羽根４０，４１は、羽根が２重構造となっており、回転中心２６と反対側へ内包した内羽根を出し入れすることによって、羽根長を伸縮自在にしている。図１１に示すように、上下風向変更羽根４０は、内部に内羽根４４が収納可能なように構成されており、内羽根４４の裏面側の両端部にはラック４５が設けられ、ラック４５は上下風向変更羽根４０の内部に収納された歯車４６とそれぞれ噛合っている。そして、両歯車４６間は軸４７で連結している。 The upper and lower wind direction changing blades 40 and 41 have a double blade structure, and the length of the blades can be extended and retracted by taking in and out the inner blades contained in the opposite side of the rotation center 26. As shown in FIG. 11, the up / down wind direction changing blade 40 is configured so that the inner blade 44 can be accommodated therein, and racks 45 are provided at both ends on the back side of the inner blade 44. The upper and lower wind direction changing blades 40 are respectively meshed with gears 46 accommodated therein. The gears 46 are connected by a shaft 47.

また、上下風向変更羽根４０の片端には歯車４８が設けられ軸４７と連結している。また、歯車４８は上下風向変更羽根４０内に連装されており、最終の歯車４８が駆動モータ４９と連結しているため、駆動モータ４９の回動によって内羽根４４は動作して上下風向変更羽根４０内に収納されたり、突出したりする。 A gear 48 is provided at one end of the up / down airflow direction changing blade 40 and is connected to the shaft 47. Further, since the gear 48 is connected to the up / down air direction changing blade 40 and the final gear 48 is connected to the drive motor 49, the inner blade 44 operates by the rotation of the drive motor 49, and the up / down air direction changing blade. It is stored in 40 or protrudes.

尚、上下風向変更羽根４１も上下風向変更羽根４０と同じ構成である。 The up / down air direction changing blade 41 has the same configuration as the up / down air direction changing blade 40.

次に図１２を用いて動作を説明するが、パネル１１の動作については、第１および２の実施の形態と同じであるため説明を省略する。 Next, the operation will be described with reference to FIG. 12. Since the operation of the panel 11 is the same as that of the first and second embodiments, the description thereof will be omitted.

第１および２の実施の形態と同様に、空気調和機１の風向変更モードを上向き方向（主
に冷房運転）に設定して運転を開始すると、パネル１１が吸込口５から前方に最も離間した位置まで移動し、図１２（ａ）に示すように、駆動モータ４３によって上下風向変更羽根４１は下向きに回動して吹出口６下部を開口し、上下風向変更羽根４１が略水平より上向きの上向き送風状態となる位置まで移動する。その後、駆動モータ４９の回動によって内羽根４４が延出する。 As in the first and second embodiments, when the air direction change mode of the air conditioner 1 is set to the upward direction (mainly cooling operation) and the operation is started, the panel 11 is farthest forward from the suction port 5. As shown in FIG. 12 (a), the up / down wind direction changing blade 41 is rotated downward by the drive motor 43 to open the lower portion of the outlet 6, and the up / down air direction changing blade 41 is directed upward from substantially horizontal. It moves to the position where it becomes an upward blowing state. Thereafter, the inner blade 44 is extended by the rotation of the drive motor 49.

一方、上下風向変更羽根４０は、駆動モータ４２の動作によって羽根の凹形状が略下向きとなるように上向きに回動して吹出口６上部を開口し、上下風向変更羽根４０が略水平より下向きとなる位置まで移動する。そして、この状態で上向き方向への送風が行われる。 On the other hand, the vertical wind direction changing blade 40 is rotated upward so that the concave shape of the blade is substantially downward by the operation of the drive motor 42 to open the upper part of the air outlet 6, and the vertical wind direction changing blade 40 is downward from substantially horizontal. Move to the position. In this state, the air is blown upward.

従って、吹出グリル７で形成された送風通路９が送風方向へ延長され且つ送風路断面積が狭められることで、吹出口を出た瞬間の気流の拡散を防ぐことができ、気流は、上下風向変更羽根４１および内羽根４４の羽根形状に沿って上向き方向もしくは水平方向に送風されるため、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。
また、上下風向変更羽根４０と上下風向変更羽根４１とにより気流を縮流し、流速を増すことで居室の奥行き方向の遠くまで風を導くことが可能となる。 Accordingly, the air passage 9 formed by the blow grill 7 is extended in the air blowing direction and the air passage cross-sectional area is narrowed, so that the diffusion of the air flow at the moment of exiting the air outlet can be prevented. Since the air is blown upward or horizontally along the blade shapes of the change blade 41 and the inner blade 44, it is possible to prevent the cold air from being directly applied to the person in the room.
In addition, the airflow is reduced by the up / down air direction changing blades 40 and the up / down air direction changing blades 41, and the flow velocity can be increased to guide the wind to a distance in the depth direction of the room.

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

空気調和機１の風向変更モードを下向き方向（主に暖房運転）に設定して運転を開始すると、パネル１１が吸込口５から前方に最も離間した位置まで移動し、図１２（ｂ）に示すように、駆動モータ４２によって上下風向変更羽根４０は上向きに回動して吹出口６上部を開口し、上下風向変更羽根４０が略鉛直より上向きの下向き送風状態となる位置まで移動する。その後、駆動モータ４９の回動によって内羽根４４が延出する。 When the wind direction change mode of the air conditioner 1 is set to the downward direction (mainly heating operation) and the operation is started, the panel 11 moves to the position farthest away from the suction port 5 and is shown in FIG. Thus, the up / down wind direction changing blade 40 is rotated upward by the drive motor 42 to open the upper portion of the air outlet 6, and the up / down air direction changing blade 40 is moved to a position where the up / down air direction changing blade 40 is in a downward blowing state upward from substantially vertical. Thereafter, the inner blade 44 is extended by the rotation of the drive motor 49.

一方、上下風向変更羽根４１は、駆動モータ４３の動作によって羽根の凹形状が斜め上向きとなるように下向きに回動して吹出口６下部を開口し、上下風向変更羽根４１が送風通路９下縁部と略平行となる位置まで移動する。そして、この状態で下向き方向への送風が行われる。 On the other hand, the up / down air direction changing blade 41 is rotated downward by the operation of the drive motor 43 so that the concave shape of the blade is obliquely upward to open the lower portion of the air outlet 6, and the up / down air direction changing blade 41 is below the air passage 9. Move to a position that is substantially parallel to the edge. In this state, air is blown in the downward direction.

従って、吹出グリル７で形成された送風通路９が送風方向へ延長され且つ送風路断面積が狭められることで、吹出口を出た瞬間の気流の拡散を防ぐことができ、気流は、上下風向変更羽根４０および内羽根４４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。 Accordingly, the air passage 9 formed by the blow grill 7 is extended in the air blowing direction and the cross section of the air passage is narrowed, so that the air current can be prevented from diffusing at the moment of exiting the air outlet. Since the change blade 40 and the inner blade 44 are guided directly to the floor of the living room along the blade shape, it is possible to prevent the person in the living room from being directly exposed to the warm air.

また、上下風向変更羽根４０と上下風向変更羽根４１とにより気流を縮流することができるため、暖房の即効性が向上する。 Moreover, since the airflow can be reduced by the up / down air direction changing blades 40 and the up / down air direction changing blades 41, the immediate effect of heating is improved.

空気調和機１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、パネル１１が吸込口５から前方に最も離間した位置まで移動し、図１２（ｃ）に示すように、駆動モータ４２および駆動モータ４３の動作によって上下風向変更羽根４０は上向きに、上下風向変更羽根４１は下向きに回動し、吹出口６の開口部上部及び下部をそれぞれ開口し、上下風向変更羽根４０、４１がそれぞれ送風通路９上縁部、下縁部と略平行となる、斜め方向への送風状態となる位置まで移動する。そして、この状態で斜め方向への送風が行われる。 When the air direction change mode of the air conditioner 1 is set to an oblique direction (cooling operation, heating operation, etc.) and the operation is started, the panel 11 moves from the suction port 5 to the position farthest forward, and FIG. As shown in FIG. 4, the up and down wind direction changing blades 40 are rotated upward and the up and down air direction changing blades 41 are rotated downward by the operations of the drive motor 42 and the drive motor 43, and the upper and lower openings of the air outlet 6 are opened. The up-and-down air direction changing blades 40 and 41 move to positions where they are in a state of blowing air in an oblique direction, which are substantially parallel to the upper and lower edges of the air passage 9, respectively. In this state, air is blown in an oblique direction.

ここで、上下風向変更羽根４０および４１において、内羽根４４は延出させても、させ
なくてもどちらでもかまわない。また、駆動モータ４２および駆動モータ４３の回動によって、上下風向変更羽根４０および上下風向変更羽根４１を所定角度でスイング動作させてもかまわない。 Here, in the up-and-down wind direction changing blades 40 and 41, the inner blade 44 may be extended or not. Further, the up / down air direction changing blade 40 and the up / down air direction changing blade 41 may be swung at a predetermined angle by the rotation of the driving motor 42 and the driving motor 43.

従って、吹出グリル７で形成された送風通路９が送風方向へ延長されることで、吹出口を出た瞬間の気流の拡散を防ぐことができ、気流は、上下風向変更羽根４０および４１（内羽根４４が延出されている場合は内羽根４４も含む）の羽根形状に沿って、居室の中央部へと導かれるため、居室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。 Accordingly, the air passage 9 formed by the blow grill 7 is extended in the blow direction, so that the air current can be prevented from diffusing at the moment when it exits the air outlet. Since the blade 44 is guided to the center of the living room along the blade shape (including the inner blade 44 when the blade 44 is extended), cold air or hot air can be directly applied to the person in the living room. This blowing state is mainly used at the start of cooling and heating operations.

また、上下風向変更羽根４０と上下風向変更羽根４１により気流を縮流することができるため、気流の指向性向上と、冷房および暖房の即効性向上が図れる。 Further, since the air flow can be reduced by the up / down air direction changing blade 40 and the up / down air direction changing blade 41, the directivity of the air flow can be improved and the immediate effect of cooling and heating can be improved.

尚、動作の説明は省略するが、各送風状態間での移行動作も可能である。 In addition, although description of operation | movement is abbreviate | omitted, the transfer operation | movement between each ventilation state is also possible.

また、上下風向変更羽根４０および４１で気流の拡散を防ぐことができるため、所定の最大角度まで気流を曲げることが可能となり、居室の左右方向への送風範囲を拡大することができる。 Moreover, since the diffusion of the airflow can be prevented by the up-and-down airflow direction changing blades 40 and 41, the airflow can be bent to a predetermined maximum angle, and the air blowing range in the left-right direction of the living room can be expanded.

以上のように、本実施の形態３においては、吹出口６の下流側上下端部にそれぞれ回転中心２６を有するに上下風向変更羽根４０と上下風向変更羽根４１の２枚の羽根を備え、上下風向変更羽根４０と上下風向変更羽根４１とは互いに独立して回転動作して、且つ、内包する内羽根４４を回転中心２６と反対側へ出し入れすることによって、羽根長を伸縮自在にすることが可能であるため、左右方向への風の吹出し角度の拡大および居室の遠方まで風を導くことが可能となる。また、上下風向変更羽根４０および４１の動作が簡単であるため、空気調和機１の停止状態から各送風モードへの移行および各送風モード間の移行が容易に行える。 As described above, in the third embodiment, the upper and lower ends of the downstream side of the air outlet 6 are provided with two blades of the upper and lower airflow direction changing blades 40 and the upper and lower airflow direction changing blades 41, respectively. The wind direction changing blade 40 and the vertical wind direction changing blade 41 rotate independently of each other, and the blade length can be extended and retracted by moving the inner blade 44 contained in and out of the rotation center 26 to the opposite side. Therefore, it is possible to expand the blowing angle of the wind in the left-right direction and to guide the wind far away from the room. Moreover, since the operation | movement of the up-and-down air direction change blade | wings 40 and 41 is simple, the transfer from the stop state of the air conditioner 1 to each ventilation mode and the transition between each ventilation mode can be performed easily.

以上のように、本発明の空気調和機は、多様な風向制御を行うことができ、居室の隅々まで風を送ることが可能であるため、室内の冷暖房の他、除湿装置や空気清浄装置にも適用できる。 As described above, since the air conditioner of the present invention can perform various wind direction control and can send wind to every corner of the living room, in addition to indoor air conditioning, a dehumidifier and an air purifier It can also be applied to.
