On the other hand, during operation, the second blade 4a2 moves outward from the air outlet 3, that is, a part of the second blade 4a2 or the entire second blade 4a2 protrudes from the air outlet 3. That is, the 2nd blade | wing 4a2 functions as a wind direction control part, and does not function as a main body outline design part.
　また、後に詳しく説明するが、端的には、第２羽根４ａ２は、水平吹き時（正面吹き時）は、図３に示されるように、第１羽根４ａ１と直接に並び、下吹き時（縦吹き時）は、図４に示されるように、第１羽根４ａ１と並列に並ぶ。また、第３羽根４ａ３は、水平吹き時も下吹き時も共に、第２羽根４ａ２とほぼ並行に並ぶ。 As will be described in detail later, the second blade 4a2 is directly aligned with the first blade 4a1 during horizontal blowing (front blowing) as shown in FIG. As shown in FIG. 4, the first blade 4 a 1 is arranged in parallel. Moreover, the 3rd blade | wing 4a3 is located in parallel with the 2nd blade | wing 4a2 at the time of horizontal blowing and the bottom blowing.
　また、第２羽根４ａ２の回動軸は、吹出口３内の上部且つスタビライザー寄りに位置している。そして、第２羽根４ａ２は、水平吹き時、吹き出し流れの進行方向でいう第１羽根４ａ１の前に移動し、第１羽根４ａ１と直列に並ぶ。なお、この第１羽根４ａ１と第２羽根４ａ２との直列配置は、図３のような側面視において、第１羽根４ａ１の上流端Ａと第２羽根４ａ２の下流端Ｂとを結ぶ仮想線Ｖよりも、第２羽根４ａ２の上流端Ｃが、下方に位置するような状態（仮想線Ｖに対して本体１から離れる側に位置する状態）であることを要する。これにより、第１羽根４ａ１および第２羽根４ａ２は、水平吹き時は、第１羽根４ａ１および第２羽根４ａ２それぞれの弦長よりも長い仮想弦長を有した１枚の仮想羽根となり、下吹き時は、個々の弦長を有した２枚の個別の羽根として機能する。すなわち、羽根自体を交換することなく風向により羽根弦長が変化する態様が得られているといえる。 Further, the rotation axis of the second blade 4a2 is located in the upper part of the air outlet 3 and closer to the stabilizer. And the 2nd blade | wing 4a2 moves in front of the 1st blade | wing 4a1 said in the advancing direction of a blowing flow at the time of horizontal blowing, and is located in series with the 1st blade | wing 4a1. The series arrangement of the first blade 4a1 and the second blade 4a2 is an imaginary line V connecting the upstream end A of the first blade 4a1 and the downstream end B of the second blade 4a2 in a side view as shown in FIG. Rather, the upstream end C of the second blade 4a2 needs to be in a state of being positioned below (a state of being positioned on the side away from the main body 1 with respect to the virtual line V). As a result, the first blade 4a1 and the second blade 4a2 become a single virtual blade having a virtual chord length longer than each of the first blade 4a1 and the second blade 4a2 during horizontal blowing, Sometimes it functions as two individual blades with individual chord lengths. That is, it can be said that the blade chord length is changed by the wind direction without replacing the blade itself.
　また、水平吹き時、直列に配置された第１羽根４ａ１と第２羽根４ａ２との間には、隙間２０が確保される。特に、本実施の形態１では、直列に並んだとき、第１羽根４ａ１の上面（本体側の面）が上向きの凸形状（本体に向けて凸形状）であり、第２羽根４ａ２の下面（本体と反対側の面）が下向きの凸形状（本体と反対側に向けて凸形状）であるように、第１羽根４ａ１および第２羽根４ａ２がそれぞれ回動して移動する。 Further, a gap 20 is secured between the first blade 4a1 and the second blade 4a2 arranged in series during horizontal blowing. In particular, in Embodiment 1, when arranged in series, the upper surface (surface on the main body side) of the first blade 4a1 has an upward convex shape (convex shape toward the main body), and the lower surface of the second blade 4a2 ( The first blade 4a1 and the second blade 4a2 rotate and move so that the surface on the opposite side of the main body has a downward convex shape (convex shape toward the opposite side of the main body).
　また、第２羽根４ａ２は、図４に示されるように、下吹き時は、吹出口３よりも部分的に外に出ると共に、図３に示されるように、水平吹き時には、吹出口３から完全に外へ出る（第２羽根４ａ２の全体が吹出口３から外に出る）。 Further, as shown in FIG. 4, the second blade 4 a 2 partially exits from the air outlet 3 when being blown downward, and from the air outlet 3 when being horizontally blown as shown in FIG. 3. It completely goes out (the entire second blade 4a2 goes out from the outlet 3).
　一方、第２羽根４ａ２は、下吹き時、第１羽根４ａ１と第３羽根４ａ３との間の位置に移動し、且つ、これら第１羽根４ａ１と第３羽根４ａ３とほぼ平行な姿勢に移動する。すなわち、第２羽根４ａ２は、下吹き時、第１羽根４ａ１と並列に並ぶ。また、このとき、第２羽根４ａ２における第１羽根４ａ１と対向する面が、第１羽根４ａ１に向けて出っ張る凸形状であり、第１羽根４ａ１における第２羽根４ａ２と対向する面が、第２羽根４ａ２に向けて出っ張る凸形状であるように、第１羽根４ａ１および第２羽根４ａ２がそれぞれ回動して移動する。 On the other hand, the second blade 4a2 moves to a position between the first blade 4a1 and the third blade 4a3 and moves to a posture substantially parallel to the first blade 4a1 and the third blade 4a3 during the bottom blowing. . That is, the 2nd blade | wing 4a2 is located in a line with the 1st blade | wing 4a1 at the time of bottom blowing. At this time, the surface of the second blade 4a2 facing the first blade 4a1 is a convex shape protruding toward the first blade 4a1, and the surface of the first blade 4a1 facing the second blade 4a2 is the second surface. The first blade 4a1 and the second blade 4a2 are rotated and moved so as to have a convex shape protruding toward the blade 4a2.
　以上のような構成を有する空気調和機においては、次のような効果が得られる。第２羽根４ａ２は、運転停止時、吹出風路３ａ内に収納されており、運転時には、吹出口３から外にせり出す。このため、第２羽根４ａ２は、ボディ外面に要求される意匠的な条件に制約されることなく、風向制御に適した形状を有することができ、風向制御に適した形状の少なくとも一つの風向制御羽根が確実に確保されることとなる。また、本体の外面の意匠の評価としては、運転停止時、外観観察において開閉部として認識できる部分は少ないほど好ましいところ、本実施の形態１では、３枚の羽根を用いておりながら、運転停止時は２枚分の開閉部だけが視認できる意匠を提供することができる。また、運転停止時の開閉部の外縁からは埃等の本体内部への侵入が少なからず懸念されるところ、本実施の形態１では、３枚の羽根を用いておりながら、運転停止時の開閉部を２枚分で抑えることで、好ましくない埃等の本体内部への侵入を抑制することも期待できる。 In the air conditioner having the above-described configuration, the following effects can be obtained. The 2nd blade | wing 4a2 is accommodated in the blowing wind path 3a at the time of a driving | operation stop, and protrudes outside from the blower outlet 3 at the time of a driving | operation. Therefore, the second blade 4a2 can have a shape suitable for wind direction control without being restricted by the design conditions required for the outer surface of the body, and at least one wind direction control having a shape suitable for wind direction control. A blade | wing will be ensured reliably. In addition, as the evaluation of the design of the outer surface of the main body, it is preferable that the number of parts that can be recognized as the opening / closing part in the appearance observation is smaller when the operation is stopped. In this Embodiment 1, the operation is stopped while using three blades. At times, it is possible to provide a design in which only two open / close portions can be visually recognized. In addition, there is a considerable concern about the outer edge of the opening / closing part when the operation is stopped from entering the inside of the main body. However, in the first embodiment, the opening / closing operation is stopped while using three blades. It can also be expected that the entry of unwanted dust and the like into the main body is suppressed by suppressing the portion by two sheets.
　また、第２羽根４ａ２は、第１羽根４ａ１と直列に並ぶ。よって、第１羽根４ａ１および第２羽根４ａ２は、水平吹き時は、第１羽根４ａ１および第２羽根４ａ２それぞれの弦長よりも長い仮想弦長を有した１枚の仮想羽根となり、下吹き時は、個々の弦長を有した２枚の個別の羽根として機能する。すなわち、羽根自体を交換することなく風向により羽根弦長が変化する態様が得られているといえる。このように個々の羽根の弦長よりも長い仮想弦長を有した仮想羽根が得られるので、水平吹き時、貫流ファンから下向きに放出された空気の流れを、長い仮想弦長を活用して、大きく前方へと転向させることができ、風向制御性を大きく向上させることができる。 The second blade 4a2 is arranged in series with the first blade 4a1. Therefore, the 1st blade | wing 4a1 and the 2nd blade | wing 4a2 become one virtual blade | wing with the virtual chord length longer than each chord length of the 1st blade | wing 4a1 and the 2nd blade | wing 4a2 at the time of horizontal blowing, Functions as two individual blades with individual chord lengths. That is, it can be said that the blade chord length is changed by the wind direction without replacing the blade itself. In this way, a virtual blade having a virtual chord length longer than the chord length of each blade is obtained, so that when flowing horizontally, the flow of air released downward from the cross-flow fan can be utilized by utilizing the long virtual chord length. , It can be largely turned forward, and the wind direction controllability can be greatly improved.
　また、水平吹き時、直列に配置された第１羽根４ａ１と第２羽根４ａ２との間には、隙間２０が確保される。このように隙間２０が確保された状態で第１羽根４ａ１と第２羽根４ａ２とが直列配置されるので、冷房時の風は、第１羽根４ａ１通過後、第２羽根４ａ２との隙間２０から第２羽根４ａ２の上下面の両方に流れ、第２羽根４ａ２の両面での温度差が小さくなるので、結露が抑制され、品質を向上させることができる。特に、本実施の形態１では、直列に並んだとき、第１羽根４ａ１の上面（本体側の面）が上向きの凸形状（本体に向けて凸形状）であり、第２羽根４ａ２の下面（本体と反対側の面）が下向きの凸形状（本体と反対側に向けて凸形状）であるように、第１羽根４ａ１および第２羽根４ａ２がそれぞれ回動して移動する。このような第１羽根４ａ１および第２羽根４ａ２の面の反りの方向の作用によって、さらに、第１羽根４ａ１と第２羽根４ａ２との間に気流が流れやすくなっており、結露の抑制効果はより高いものとなっている。 Further, a gap 20 is secured between the first blade 4a1 and the second blade 4a2 arranged in series during horizontal blowing. Since the first blade 4a1 and the second blade 4a2 are arranged in series in a state where the gap 20 is secured in this way, the air during cooling passes through the first blade 4a1 and then from the gap 20 with the second blade 4a2. Since it flows to both the upper and lower surfaces of the second blade 4a2 and the temperature difference between both surfaces of the second blade 4a2 becomes small, dew condensation is suppressed and the quality can be improved. In particular, in Embodiment 1, when arranged in series, the upper surface (surface on the main body side) of the first blade 4a1 has an upward convex shape (convex shape toward the main body), and the lower surface of the second blade 4a2 ( The first blade 4a1 and the second blade 4a2 rotate and move so that the surface on the opposite side of the main body has a downward convex shape (convex shape toward the opposite side of the main body). Due to the action of the warp direction of the surfaces of the first blade 4a1 and the second blade 4a2, the airflow easily flows between the first blade 4a1 and the second blade 4a2, and the effect of suppressing dew condensation is It is higher.
　また、第２羽根４ａ２は、図４に示されるように、下吹き時は、吹出口３よりも部分的に外に出ると共に、図３に示されるように、水平吹き時には、吹出口３から完全に外へ出る（第２羽根４ａ２の全体が吹出口３から外に出る）。このため、吹出口３から出た第２羽根４ａ２の部分では、本体１の側面１ｅの側方からの流れの抑え込み作用から解放されるので、風向制御が行いやすいという利点が得られる。 Further, as shown in FIG. 4, the second blade 4 a 2 partially exits from the air outlet 3 when being blown downward, and from the air outlet 3 when being horizontally blown as shown in FIG. 3. It completely goes out (the entire second blade 4a2 goes out from the outlet 3). For this reason, in the part of the 2nd blade | wing 4a2 which came out from the blower outlet 3, since it is released | released from the suppression effect | action of the flow from the side of the side surface 1e of the main body 1, the advantage that it is easy to perform wind direction control is acquired.
　また、第２羽根４ａ２は、下吹き時、第１羽根４ａ１と並列に並ぶ。さらに、第２羽根４ａ２における第１羽根４ａ１と対向する面が、第１羽根４ａ１に向けて出っ張る凸形状であり、第１羽根４ａ１における第２羽根４ａ２と対向する面が、第２羽根４ａ２に向けて出っ張る凸形状であるように、第１羽根４ａ１および第２羽根４ａ２がそれぞれ回動して移動する。このため、暖房時、第１羽根４ａ１と第２羽根４ａ２との間を流れる気流は、第１羽根４ａ１の凸形状と第２羽根４ａ２の凸形状とで囲まれた領域を流れるので、徐々に縮流されることで、剥離渦が抑制された後、さらに、徐々に拡大流れとなることで、流れの乱れが抑制される。よって、総括的にみて、気流の直進性が向上し、気流の床面到達距離が延長されて、利用者の足元まで暖房できる効果が増大する。 Further, the second blade 4a2 is arranged in parallel with the first blade 4a1 when the lower blade is blown. Furthermore, the surface of the second blade 4a2 that faces the first blade 4a1 is a convex shape that protrudes toward the first blade 4a1, and the surface of the first blade 4a1 that faces the second blade 4a2 is the second blade 4a2. The first blade 4a1 and the second blade 4a2 rotate and move so as to have a convex shape projecting toward each other. For this reason, during heating, the airflow flowing between the first blade 4a1 and the second blade 4a2 flows in a region surrounded by the convex shape of the first blade 4a1 and the convex shape of the second blade 4a2, so gradually By contracting the flow, after the separation vortex is suppressed, the flow is gradually expanded, and the turbulence of the flow is suppressed. Therefore, as a whole, the straightness of the airflow is improved, the reach of the airflow to the floor surface is extended, and the effect of heating up to the user's feet increases.
　実施の形態２．
　次に、図５～図８を参照しながら、本発明の実施の形態２について説明する。図５は、本発明の実施の形態２に関する、図１と同態様の図である。図６は、本実施の形態２に関する、図２と同態様の図である。図７は、本実施の形態２に関する、図３と同態様の図である。図８は、本実施の形態２に関する、図４と同態様の図である。なお、本実施の形態２は、以下に説明する部分以外の構成は、上述した実施の形態１と同様であるものとする。 Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a view of the same mode as FIG. 1 regarding the second embodiment of the present invention. FIG. 6 is a diagram of the same mode as FIG. FIG. 7 is a diagram of the same mode as FIG. FIG. 8 is a diagram of the same mode as FIG. The configuration of the second embodiment is the same as that of the first embodiment described above except for the portions described below.
　本実施の形態２の空気調和機２００においては、本体１の下面１ｄにのみ、吹出口２０３が設けられている。すなわち、吹出口２０３は、本体１の前面１ａには開口していない。 In the air conditioner 200 of the second embodiment, the air outlet 203 is provided only on the lower surface 1d of the main body 1. That is, the air outlet 203 is not open to the front surface 1 a of the main body 1.
　空気調和機２００には、上下風向ベーン２０４ａが設けられており、上下風向ベーン２０４ａは、上記実施の形態１における第１羽根４ａ１と第２羽根４ａ２とを含んでおり、上記実施の形態１における第３羽根４ａ３に相当する部材は含まれていない。 The air conditioner 200 is provided with an up-and-down airflow direction vane 204a. The up-and-down airflow direction vane 204a includes the first blade 4a1 and the second blade 4a2 in the first embodiment, and in the first embodiment. A member corresponding to the third blade 4a3 is not included.
　このような本実施の形態２においても、上述した実施の形態１と同様な利点が得られている。さらに、本実施の形態２では、吹出口が本体の下面にのみ開口し前面には開口していないので、本体内部の機能部品から生じる騒音（例えば貫流ファンの駆動モータ音、貫流ファンの風切音、熱交換器内の冷媒流通音）が前方に向けて直接漏れることが抑制されており、意匠的な条件に制約されない羽根による風向制御性の向上と、騒音抑制との両立が図られている。また、上述したように第２羽根が本体外にせり出し第１羽根と直列的に並ぶので、本体の前面に吹出口を有しない態様でも好適な水平吹きが可能であり、騒音抑制と快適性との両立も図ることができる。 Also in this second embodiment, the same advantages as in the first embodiment described above are obtained. Further, in the second embodiment, since the air outlet opens only on the lower surface of the main body and does not open on the front surface, noise generated from the functional components inside the main body (for example, the driving motor sound of the cross-flow fan, the wind-off of the cross-flow fan) Noise, refrigerant circulation sound in the heat exchanger) is prevented from leaking directly forward, and improvement in wind direction controllability by blades not restricted by design conditions and noise suppression are achieved. Yes. In addition, as described above, since the second blade protrudes outside the main body and is arranged in series with the first blade, it is possible to perform horizontal blowing suitable for an aspect having no air outlet on the front surface of the main body, noise suppression and comfort. Can also be achieved.
　実施の形態３．
　次に、図９～図１３を参照しながら、本発明の実施の形態３について説明する。図９および図１０は、本発明の実施の形態３に関する、図１と同態様の図である。特に、図９は、下吹き運転時（縦吹き時）の状態を示し、図１０は、水平吹き運転時（正面吹き時）の状態を示す。図１１は、本実施の形態３に関する、図２と同態様の図である。図１２は、本実施の形態３に関する、図３と同態様の図である。図１３は、本実施の形態３に関する、図４と同態様の図である。なお、本実施の形態３は、以下に説明する部分以外の構成は、上述した実施の形態１と同様であるものとする。 Embodiment 3 FIG.
Next, Embodiment 3 of the present invention will be described with reference to FIGS. 9 and 10 are diagrams of the same mode as FIG. 1 relating to the third embodiment of the present invention. In particular, FIG. 9 shows a state during a down blowing operation (at the time of vertical blowing), and FIG. 10 shows a state during a horizontal blowing operation (at the time of front blowing). FIG. 11 is a diagram of the same mode as FIG. FIG. 12 is a diagram of the same mode as FIG. FIG. 13 is a diagram of the same mode as FIG. The configuration of the third embodiment is the same as that of the first embodiment described above except for the parts described below.
　本実施の形態３の空気調和機３００において、吹出口３０３は、下面１ｄの前部のエリアと、前面１ａの下部のエリアとにまたがって、形成されている。上下風向ベーン３０４ａは、第１羽根４ａ１と、第２羽根４ａ２と、シャッタ４ａ４とを含んでいる。これら第１羽根４ａ１、第２羽根４ａ２およびシャッタ４ａ４は、それぞれ、個別の駆動源を有している。第１羽根４ａ１および第２羽根４ａ２は、上記実施の形態１と同様なものである。 In the air conditioner 300 of the third embodiment, the air outlet 303 is formed across the front area of the lower surface 1d and the lower area of the front surface 1a. The up / down wind direction vane 304a includes a first blade 4a1, a second blade 4a2, and a shutter 4a4. Each of the first blade 4a1, the second blade 4a2, and the shutter 4a4 has a separate drive source. The first blade 4a1 and the second blade 4a2 are the same as those in the first embodiment.
　一方、シャッタ４ａ４は、吹出口３０３における、前面１ａの下部のエリアを開閉するものである。シャッタ４ａ４は、本体１の前面１ａの延びる方向に沿って延びている。シャッタ４ａ４は、運転停止時、装置ボディの前面下部の外面を構成しており、本体外郭意匠部として機能する。 On the other hand, the shutter 4a4 opens and closes the area below the front surface 1a at the air outlet 303. The shutter 4a4 extends along the direction in which the front surface 1a of the main body 1 extends. When the operation is stopped, the shutter 4a4 constitutes the outer surface of the lower part of the front surface of the apparatus body and functions as a main body outer design portion.
　また、シャッタ４ａ４は、本体１の前面１ａの延びる方向に沿って移動し、つまり、上下にスライドする。シャッタ４ａ４は、水平吹き運転時は、上方にスライドして、面１ａの下部のエリアの吹出口３０３を開放し、貫流ファン８から吹き出された空気が前方に向けて流れることを許容する。一方、シャッタ４ａ４は、下吹き運転時は、下方にスライドして、面１ａの下部のエリアの吹出口３０３を閉じると共に、貫流ファン８から吹き出された空気が、下方に流れるようにガイドする。 The shutter 4a4 moves along the direction in which the front surface 1a of the main body 1 extends, that is, slides up and down. During the horizontal blowing operation, the shutter 4a4 slides upward to open the air outlet 303 in the area below the surface 1a, and allows the air blown from the cross-flow fan 8 to flow forward. On the other hand, during the downward blowing operation, the shutter 4a4 slides downward to close the outlet 303 in the lower area of the surface 1a and guides the air blown from the cross-flow fan 8 to flow downward.
　このような本実施の形態３においても、上述した実施の形態１と同様な利点が得られている。さらに、本実施の形態３でも、吹出口が本体の下面にのみ開口し前面には開口していないので、本体内部の機能部品から生じる騒音が前方に向けて直接漏れることが抑制されており、意匠的な条件に制約されない羽根による風向制御性の向上と、騒音抑制との両立が図られている。また、上述したように第２羽根が本体外にせり出し第１羽根と直列的に並ぶので、本体の前面に吹出口を有しない態様でも好適な水平吹きが可能であり、騒音抑制と快適性との両立も図ることができる。 Also in this third embodiment, the same advantages as in the first embodiment described above are obtained. Furthermore, also in this third embodiment, since the air outlet opens only on the lower surface of the main body and does not open on the front surface, it is suppressed that noise generated from the functional components inside the main body leaks directly toward the front, The improvement of the wind direction controllability by the blades not restricted by the design conditions and the noise suppression are both achieved. In addition, as described above, since the second blade protrudes outside the main body and is arranged in series with the first blade, it is possible to perform horizontal blowing suitable for an aspect having no air outlet on the front surface of the main body, noise suppression and comfort. Can also be achieved.
　実施の形態４．
　次に、図１４～図１８を参照しながら、本発明の実施の形態４について説明する。図１４は、本発明の実施の形態４における空気調和機の部屋から見たときの設置概要図である。図１５～図１８は、図１４の空気調和機の内部構造を側方から示す図である。なお、図１５は、空気調和機の運転停止時の状態を示し、図１６は、上吹き運転時（縦吹き時）の状態を示し、図１７は、水平吹き運転時（正面吹き時）の状態を示し、図１８は、下吹き運転時（縦吹き時）の状態を示す。なお、本実施の形態４は、以下に説明する部分以外の構成は、上述した実施の形態１と同様であるものとする。 Embodiment 4 FIG.
Next, a fourth embodiment of the present invention will be described with reference to FIGS. FIG. 14 is an installation schematic diagram when viewed from the room of the air conditioner according to Embodiment 4 of the present invention. 15 to 18 are views showing the internal structure of the air conditioner of FIG. 14 from the side. 15 shows a state when the operation of the air conditioner is stopped, FIG. 16 shows a state when the top blowing operation (longitudinal blowing), and FIG. 17 shows a state when the horizontal blowing operation (front blowing). A state is shown and FIG. 18 shows the state at the time of a bottom blowing operation (at the time of a longitudinal blow). The configuration of the fourth embodiment is the same as that of the first embodiment described above except for the portions described below.
　空気調和機４００は、床置き型であり、空調対象空間である部屋１１の床１１ｂに設置されている。空気調和機４００は、後述する吸込口４０２ｃ、ドレンパン４０９ｂおよび第３羽根４ａ５を除き、フィルタ５、熱交換器７、貫流ファン８、スタビライザー９、ガイドウォール１０、第１羽根４ａ１および第２羽根４ａ２が、上記実施の形態１の空気調和機の構成と、上下逆に設けられている。 The air conditioner 400 is a floor-standing type and is installed on the floor 11b of the room 11 which is a space to be air-conditioned. The air conditioner 400 is provided with a filter 5, a heat exchanger 7, a cross-flow fan 8, a stabilizer 9, a guide wall 10, a first blade 4a1, and a second blade 4a2 except for a suction port 402c, a drain pan 409b, and a third blade 4a5 described later. However, it is provided upside down from the configuration of the air conditioner of the first embodiment.
　図１４に図示されるように、空気調和機（室内機）４００は、本体１によって、空気調和機４００の外郭が構成されている。本体１は、箱状をなしており、部屋１１の壁１１ａに対面する背面１ｃと、背面１ｃの反対側である前面１ａと、上面１ｂと、下面１ｄと、左右一対の側面１ｅとを含んでいる。 As shown in FIG. 14, the air conditioner (indoor unit) 400 includes an outer body of the air conditioner 400 by the main body 1. The main body 1 has a box shape, and includes a back surface 1c facing the wall 11a of the room 11, a front surface 1a opposite to the back surface 1c, an upper surface 1b, a lower surface 1d, and a pair of left and right side surfaces 1e. It is out.
　前面１ａの下部には、室内空気を空気調和機４００内に吸い込むためのグリル型の吸込口４０２ｃが形成されている。また、前面１ａには、前面グリル６が取り付けられ、前面グリル６の本体高さ方向でいう上寄りの部分には、吸込口２ａが開口している。吸込口２ａは、前面グリル６を、横幅方向に延びている。吸込口２ａの下流側には、導風壁６ａが設けられている。吸込口２ａの下流側の流路の前面側は、前面グリル６の裏面で形成され、吸込口２ａの下流側の流路の背面側は、導風壁６ａで形成されている。導風壁６ａは、吸込口２ａの上方の前面グリル６から背面側に延び且つ上方に延びている。 A grill-type suction port 402c for sucking room air into the air conditioner 400 is formed in the lower part of the front surface 1a. Further, a front grill 6 is attached to the front face 1a, and a suction port 2a is opened in an upper portion of the front grill 6 in the main body height direction. The suction port 2a extends through the front grill 6 in the lateral width direction. An air guide wall 6a is provided on the downstream side of the suction port 2a. The front side of the flow path on the downstream side of the suction port 2a is formed by the back surface of the front grill 6, and the back side of the flow path on the downstream side of the suction port 2a is formed by the air guide wall 6a. The air guide wall 6a extends from the front grill 6 above the suction port 2a to the back side and extends upward.
　本体１の上面１ｂには、調整された空気を室内に供給するための吹出口３が形成されている。厳密には、吹出口３は、上面１ｂの前部のエリアと、前面１ａの上部のエリアとにまたがって、形成されている。 The blower outlet 3 for supplying the adjusted air indoors is formed in the upper surface 1b of the main body 1. Strictly speaking, the air outlet 3 is formed across the front area of the upper surface 1b and the upper area of the front surface 1a.

The heat exchanger 7 is provided on the downstream side of the filter 5 and on the upstream side of the cross-flow fan 8 in the air path from the suction ports 402 c and 2 a to the blower outlet 3 (center portion inside the main body 1). . In FIG. 15, the shape of the heat exchanger 7 is such that it surrounds the front portion and the lower portion of the cross-flow fan 8, but is only an example and is not particularly limited.
　熱交換器７は、圧縮機、室外熱交換器、及び絞り装置などを有する周知の態様でよい室外機に接続されて冷凍サイクルを構成しているものとする。また、熱交換器７には、例えば伝熱管と多数のフィンとにより構成されるクロスフィン式のフィン・アンド・チューブ型熱交換器が用いられている。 It is assumed that the heat exchanger 7 is connected to an outdoor unit that may be a well-known embodiment having a compressor, an outdoor heat exchanger, a throttling device, and the like and constitutes a refrigeration cycle. Further, as the heat exchanger 7, for example, a cross fin type fin-and-tube heat exchanger composed of a heat transfer tube and a large number of fins is used.
　スタビライザー９は、吸込側風路Ｅ１と吹出側風路Ｅ２とを区画するもので、図１５に図示されるように熱交換器７の上側に設けられている。吸込側風路Ｅ１は、スタビライザー９の下方に位置し、吹出側風路Ｅ２は、スタビライザー９の上方に位置している。 The stabilizer 9 divides the suction side air passage E1 and the blowout side air passage E2, and is provided on the upper side of the heat exchanger 7 as shown in FIG.

　スタビライザー９は、吸込側流路Ｅ１と吹出側流路Ｅ２とを分離する舌部９ａと、吹出口３の吹出風路３ａの下壁面（前面側壁面）であるディフューザー３ａ１とを有する。また、熱交換器７の下方には、熱交換器７から滴下される水滴を一時貯水するドレンパン４０９ｂが設けられている。 The stabilizer 9 includes a tongue portion 9a that separates the suction side flow path E1 and the blowout side flow path E2, and a diffuser 3a1 that is a lower wall surface (front side wall surface) of the blowout air passage 3a of the blowout port 3. A drain pan 409 b that temporarily stores water droplets dripped from the heat exchanger 7 is provided below the heat exchanger 7.
　吹出風路３ａには、上下風向ベーン４ａが設けられている。上下風向ベーン４ａは、第１羽根４ａ１と、第２羽根４ａ２と、第３羽根４ａ５とを含んでいる。これら第１羽根４ａ１、第２羽根４ａ２および第３羽根４ａ５は、それぞれ、個別の駆動源を有しており、個別に回動される。 The up-and-down wind direction vane 4a is provided in the blowing wind path 3a. The up-and-down airflow direction vane 4a includes a first blade 4a1, a second blade 4a2, and a third blade 4a5. Each of the first blade 4a1, the second blade 4a2, and the third blade 4a5 has an individual drive source, and is individually rotated.
　第１羽根４ａ１は、運転停止時、吹出口３のうち上面１ｂの前部のエリアを閉じており、装置ボディの外面を構成している。つまり、第１羽根４ａ１は、風向制御部と本体外郭意匠部として兼用されている。第１羽根４ａ１の、運転停止時における下面（風路側面）は、凸形状に形成されている。また、第１羽根４ａ１は、回動可能に設けられており、第１羽根４ａ１の回動軸は、吹出風路３ａ内の上部のガイドウォール寄りに位置している。 The first blade 4a1 closes the front area of the upper surface 1b of the outlet 3 when the operation is stopped, and constitutes the outer surface of the apparatus body. That is, the 1st blade | wing 4a1 is combined as a wind direction control part and a main body outline design part. The lower surface (airway side surface) of the first blade 4a1 when the operation is stopped is formed in a convex shape. Moreover, the 1st blade | wing 4a1 is provided so that rotation is possible, and the rotating shaft of the 1st blade | wing 4a1 is located near the guide wall of the upper part in the blowing wind path 3a.
　第３羽根４ａ５は、運転停止時、吹出口３のうち前面１ａの上部のエリアを閉じており、装置ボディの外面を構成している。つまり、第３羽根４ａ５もまた、風向制御部と本体外郭意匠部として兼用されている。 When the operation is stopped, the third blade 4a5 closes the area above the front surface 1a of the air outlet 3 and constitutes the outer surface of the apparatus body. That is, the 3rd blade | wing 4a5 is also used as a wind direction control part and a main body outline design part.
　第２羽根４ａ２は、運転停止時、吹出風路３ａ内に収納されており、第１羽根４ａ１と貫流ファン８との間、且つ、第３羽根４ａ５と貫流ファン８との間に配置されている。より詳細には、運転停止時、第２羽根４ａ２の全体が、本体１内に収納されている。一方、第２羽根４ａ２は、運転時には、吹出口３から外にせり出す。すなわち、第２羽根４ａ２は、風向制御部として機能し、本体外郭意匠部としては機能しない。 The second blade 4a2 is accommodated in the blowout air passage 3a when the operation is stopped, and is disposed between the first blade 4a1 and the once-through fan 8 and between the third blade 4a5 and the once-through fan 8. Yes. More specifically, the entire second blade 4a2 is accommodated in the main body 1 when the operation is stopped. On the other hand, the 2nd blade | wing 4a2 protrudes outside from the blower outlet 3 at the time of a driving | operation. That is, the 2nd blade | wing 4a2 functions as a wind direction control part, and does not function as a main body outline design part.
　また、後に詳しく説明するが、端的には、第２羽根４ａ２は、水平吹き時（正面吹き時）は、図１７に示されるように、第１羽根４ａ１と直接に並び、上吹き時（縦吹き時）は、図１６に示されるように、第１羽根４ａ１と並列に並ぶ。さらに、図１８に示されるように、下吹き時（縦吹き時）には、第１羽根４ａ１と第２羽根４ａ２とが前後に並ぶ。 As will be described in detail later, the second blade 4a2 is directly aligned with the first blade 4a1 during horizontal blowing (front blowing) as shown in FIG. As shown in FIG. 16, it is arranged in parallel with the first blade 4a1. Further, as shown in FIG. 18, the first blade 4a1 and the second blade 4a2 are arranged in the front-rear direction during the bottom blowing (vertical blowing).
　第３羽根４ａ５は、上吹き時には、運転停止時と同じ位置および姿勢にある。第３羽根４ａ５は、水平吹き時には、上吹き時と同じ姿勢であり且つ上吹き時より上昇することでスタビライザー９と協働して空気を第２羽根４ａ２の下面に向けてガイドする。第３羽根４ａ５は、下吹き時には、吹出口３の前面１ａの上部のエリアを開放する。このとき、第３羽根４ａ５は、第３羽根４ａ５の前部が第３羽根４ａ５の後部よりも下方に位置するように、傾いている。これにより、第３羽根４ａ５は、出口３の前面１ａの上部のエリアを通過する空気を、下方に向けてガイドする。 The third blade 4a5 is in the same position and posture as when the operation is stopped when the top blows. The 3rd blade | wing 4a5 is the same attitude | position as the time of top blowing at the time of horizontal blowing, and guides air toward the lower surface of the 2nd blade | wing 4a2 in cooperation with the stabilizer 9 by raising from the time of top blowing. The 3rd blade | wing 4a5 opens the area of the upper part of the front surface 1a of the blower outlet 3 at the time of bottom blowing. At this time, the third blade 4a5 is inclined such that the front portion of the third blade 4a5 is positioned below the rear portion of the third blade 4a5. Thereby, the 3rd blade | wing 4a5 guides the air which passes the area of the upper part of the front surface 1a of the exit 3 toward the downward direction.
　また、第２羽根４ａ２の回動軸は、吹出口３内の下部のスタビライザー寄りに位置している。そして、第２羽根４ａ２は、水平吹き時、吹き出し流れの進行方向でいう第１羽根４ａ１の前に移動し、第１羽根４ａ１と直列に並ぶ。なお、この第１羽根４ａ１と第２羽根４ａ２との直列配置は、図１７のような側面視において、第１羽根４ａ１の上流端Ａと第２羽根４ａ２の下流端Ｂとを結ぶ仮想線Ｖよりも、第２羽根４ａ２の上流端Ｃが、上方に位置するような状態（仮想線Ｖに対して本体１から離れる側に位置する状態）であることを要する。これにより、第１羽根４ａ１および第２羽根４ａ２は、水平吹き時は、第１羽根４ａ１および第２羽根４ａ２それぞれの弦長よりも長い仮想弦長を有した１枚の仮想羽根となり、下吹き時は、個々の弦長を有した２枚の個別の羽根として機能する。すなわち、羽根自体を交換することなく風向により羽根弦長が変化する態様が得られているといえる。 Further, the rotation axis of the second blade 4a2 is located near the lower stabilizer in the outlet 3. And the 2nd blade | wing 4a2 moves in front of the 1st blade | wing 4a1 said in the advancing direction of a blowing flow at the time of horizontal blowing, and is located in series with the 1st blade | wing 4a1. The series arrangement of the first blade 4a1 and the second blade 4a2 is an imaginary line V connecting the upstream end A of the first blade 4a1 and the downstream end B of the second blade 4a2 in a side view as shown in FIG. Rather, the upstream end C of the second blade 4a2 needs to be in a state of being positioned upward (a state of being positioned on the side away from the main body 1 with respect to the virtual line V). As a result, the first blade 4a1 and the second blade 4a2 become a single virtual blade having a virtual chord length longer than each of the first blade 4a1 and the second blade 4a2 during horizontal blowing, Sometimes it functions as two individual blades with individual chord lengths. That is, it can be said that the blade chord length is changed by the wind direction without replacing the blade itself.
　また、水平吹き時、直列に配置された第１羽根４ａ１と第２羽根４ａ２との間には、隙間２０が確保される。特に、本実施の形態１では、直列に並んだとき、第１羽根４ａ１の下面（本体側の面）が下向きの凸形状（本体に向けて凸形状）であり、第２羽根４ａ２の上面（本体と反対側の面）が上向きの凸形状（本体と反対側に向けて凸形状）であるように、第１羽根４ａ１および第２羽根４ａ２がそれぞれ回動して移動する。 Further, a gap 20 is secured between the first blade 4a1 and the second blade 4a2 arranged in series during horizontal blowing. In particular, in Embodiment 1, when arranged in series, the lower surface (surface on the main body side) of the first blade 4a1 has a downward convex shape (convex shape toward the main body), and the upper surface of the second blade 4a2 ( The first blade 4a1 and the second blade 4a2 rotate and move so that the surface opposite to the main body has an upward convex shape (convex shape toward the opposite side of the main body).
　また、第２羽根４ａ２は、図１６に示されるように、上吹き時は、吹出口３よりも部分的に外に出ると共に、図１７に示されるように、水平吹き時には、吹出口３から完全に外へ出る（第２羽根４ａ２の全体が吹出口３から外に出る）。 Further, as shown in FIG. 16, the second blade 4a2 partially exits from the air outlet 3 when it is blown upward, and from the air outlet 3 when it is horizontally blown as shown in FIG. It completely goes out (the entire second blade 4a2 goes out from the outlet 3).
　一方、第２羽根４ａ２は、上吹き時、第１羽根４ａ１と第３羽根４ａ５との間の位置に移動し、且つ、これら第１羽根４ａ１と第３羽根４ａ５とほぼ平行な姿勢に移動する。すなわち、第２羽根４ａ２は、上吹き時、第１羽根４ａ１と並列に並ぶ。また、このとき、第２羽根４ａ２における第１羽根４ａ１と対向する面が、第１羽根４ａ１に向けて出っ張る凸形状であり、第１羽根４ａ１における第２羽根４ａ２と対向する面が、第２羽根４ａ２に向けて出っ張る凸形状であるように、第１羽根４ａ１および第２羽根４ａ２がそれぞれ回動して移動する。 On the other hand, the second blade 4a2 moves to a position between the first blade 4a1 and the third blade 4a5 and moves in a posture substantially parallel to the first blade 4a1 and the third blade 4a5 during the upper blowing. . That is, the 2nd blade | wing 4a2 is located in a line with the 1st blade | wing 4a1 at the time of top blowing. At this time, the surface of the second blade 4a2 facing the first blade 4a1 is a convex shape protruding toward the first blade 4a1, and the surface of the first blade 4a1 facing the second blade 4a2 is the second surface. The first blade 4a1 and the second blade 4a2 are rotated and moved so as to have a convex shape protruding toward the blade 4a2.
　以上のような構成を有する空気調和機においても、実施の形態１と同様、次のような効果が得られる。第２羽根４ａ２は、運転停止時、吹出風路３ａ内に収納されており、運転時には、吹出口３から外にせり出す。このため、第２羽根４ａ２は、ボディ外面に要求される意匠的な条件に制約されることなく、風向制御に適した形状を有することができ、風向制御に適した形状の少なくとも一つの風向制御羽根が確実に確保されることとなる。また、本体の外面の意匠の評価としては、運転停止時、外観観察において開閉部として認識できる部分は少ないほど好ましいところ、本実施の形態１では、３枚の羽根を用いておりながら、運転停止時は２枚分の開閉部だけが視認できる意匠を提供することができる。また、運転停止時の開閉部の外縁からは埃等の本体内部への侵入が少なからず懸念されるところ、本実施の形態１では、３枚の羽根を用いておりながら、運転停止時の開閉部を２枚分で抑えることで、好ましくない埃等の本体内部への侵入を抑制することも期待できる。 Also in the air conditioner having the above-described configuration, the following effects can be obtained as in the first embodiment. The 2nd blade | wing 4a2 is accommodated in the blowing wind path 3a at the time of a driving | operation stop, and protrudes outside from the blower outlet 3 at the time of a driving | operation. Therefore, the second blade 4a2 can have a shape suitable for wind direction control without being restricted by the design conditions required for the outer surface of the body, and at least one wind direction control having a shape suitable for wind direction control. A blade | wing will be ensured reliably. In addition, as the evaluation of the design of the outer surface of the main body, it is preferable that the number of parts that can be recognized as the opening / closing part in the appearance observation is smaller when the operation is stopped. In this Embodiment 1, the operation is stopped while using three blades. At times, it is possible to provide a design in which only two open / close portions can be visually recognized. In addition, there is a considerable concern about the outer edge of the opening / closing part when the operation is stopped from entering the inside of the main body. However, in the first embodiment, the opening / closing operation is stopped while using three blades. It can also be expected that the entry of unwanted dust and the like into the main body is suppressed by suppressing the portion by two sheets.
　また、第２羽根４ａ２は、第１羽根４ａ１と直列に並ぶ。よって、第１羽根４ａ１および第２羽根４ａ２は、水平吹き時は、第１羽根４ａ１および第２羽根４ａ２それぞれの弦長よりも長い仮想弦長を有した１枚の仮想羽根となり、上吹き時は、個々の弦長を有した２枚の個別の羽根として機能する。すなわち、羽根自体を交換することなく風向により羽根弦長が変化する態様が得られているといえる。このように個々の羽根の弦長よりも長い仮想弦長を有した仮想羽根が得られるので、水平吹き時、貫流ファンから上向きに放出された空気の流れを、長い仮想弦長を活用して、大きく前方へと転向させることができ、風向制御性を大きく向上させることができる。 The second blade 4a2 is arranged in series with the first blade 4a1. Therefore, the first blade 4a1 and the second blade 4a2 become one virtual blade having a virtual chord length longer than each of the first blade 4a1 and the second blade 4a2 during horizontal blowing, Functions as two individual blades with individual chord lengths. That is, it can be said that the blade chord length is changed by the wind direction without replacing the blade itself. In this way, virtual blades with virtual string lengths longer than the individual string lengths of individual blades can be obtained, so that when blowing horizontally, the flow of air released upward from the cross-flow fan is utilized by utilizing the long virtual string length. , It can be largely turned forward, and the wind direction controllability can be greatly improved.
　また、水平吹き時、直列に配置された第１羽根４ａ１と第２羽根４ａ２との間には、隙間２０が確保される。このように隙間２０が確保された状態で第１羽根４ａ１と第２羽根４ａ２とが直列配置されるので、冷房時の風は、第１羽根４ａ１通過後、第２羽根４ａ２との隙間２０から第２羽根４ａ２の上下面の両方に流れ、第２羽根４ａ２の両面での温度差が小さくなるので、結露が抑制され、品質を向上させることができる。特に、本実施の形態１では、直列に並んだとき、第１羽根４ａ１の下面（本体側の面）が下向きの凸形状（本体に向けて凸形状）であり、第２羽根４ａ２の上面（本体と反対側の面）が上向きの凸形状（本体と反対側に向けて凸形状）であるように、第１羽根４ａ１および第２羽根４ａ２がそれぞれ回動して移動する。このような第１羽根４ａ１および第２羽根４ａ２の面の反りの方向の作用によって、さらに、第１羽根４ａ１と第２羽根４ａ２との間に気流が流れやすくなっており、結露の抑制効果はより高いものとなっている。 Further, a gap 20 is secured between the first blade 4a1 and the second blade 4a2 arranged in series during horizontal blowing. Since the first blade 4a1 and the second blade 4a2 are arranged in series in a state where the gap 20 is secured in this way, the air during cooling passes through the first blade 4a1 and then from the gap 20 with the second blade 4a2. Since it flows to both the upper and lower surfaces of the second blade 4a2 and the temperature difference between both surfaces of the second blade 4a2 becomes small, dew condensation is suppressed and the quality can be improved. In particular, in Embodiment 1, when arranged in series, the lower surface (surface on the main body side) of the first blade 4a1 has a downward convex shape (convex shape toward the main body), and the upper surface of the second blade 4a2 ( The first blade 4a1 and the second blade 4a2 rotate and move so that the surface opposite to the main body has an upward convex shape (convex shape toward the opposite side of the main body). Due to the action of the warp direction of the surfaces of the first blade 4a1 and the second blade 4a2, the airflow easily flows between the first blade 4a1 and the second blade 4a2, and the effect of suppressing dew condensation is It is higher.
　また、第２羽根４ａ２は、図１６に示されるように、上吹き時は、吹出口３よりも部分的に外に出ると共に、図１７に示されるように、水平吹き時には、吹出口３から完全に外へ出る（第２羽根４ａ２の全体が吹出口３から外に出る）。このため、吹出口３から出た第２羽根４ａ２の部分では、本体１の側面１ｅの側方からの流れの抑え込み作用から解放されるので、風向制御が行いやすいという利点が得られる。 Further, as shown in FIG. 16, the second blade 4a2 partially exits from the air outlet 3 when it is blown upward, and from the air outlet 3 when it is horizontally blown as shown in FIG. It completely goes out (the entire second blade 4a2 goes out from the outlet 3). For this reason, in the part of the 2nd blade | wing 4a2 which came out from the blower outlet 3, since it is released | released from the suppression effect | action of the flow from the side of the side surface 1e of the main body 1, the advantage that it is easy to perform wind direction control is acquired.
　また、第２羽根４ａ２は、上吹き時、第１羽根４ａ１と並列に並ぶ。さらに、第２羽根４ａ２における第１羽根４ａ１と対向する面が、第１羽根４ａ１に向けて出っ張る凸形状であり、第１羽根４ａ１における第２羽根４ａ２と対向する面が、第２羽根４ａ２に向けて出っ張る凸形状であるように、第１羽根４ａ１および第２羽根４ａ２がそれぞれ回動して移動する。このため、第１羽根４ａ１と第２羽根４ａ２との間を流れる気流は、第１羽根４ａ１の凸形状と第２羽根４ａ２の凸形状とで囲まれた領域を流れるので、徐々に縮流されることで、剥離渦が抑制された後、さらに、徐々に拡大流れとなることで、流れの乱れが抑制される。よって、総括的にみて、気流の直進性が向上し、気流の到達距離が延長されて、室内全体に空気調和の効果が行き渡りやすいという利点がある。 Further, the second blade 4a2 is arranged in parallel with the first blade 4a1 when top blowing. Furthermore, the surface of the second blade 4a2 that faces the first blade 4a1 is a convex shape that protrudes toward the first blade 4a1, and the surface of the first blade 4a1 that faces the second blade 4a2 is the second blade 4a2. The first blade 4a1 and the second blade 4a2 rotate and move so as to have a convex shape projecting toward each other. For this reason, since the airflow flowing between the first blade 4a1 and the second blade 4a2 flows in the region surrounded by the convex shape of the first blade 4a1 and the convex shape of the second blade 4a2, it is gradually reduced. Thus, after the separation vortex is suppressed, the turbulence of the flow is further suppressed by gradually expanding the flow. Therefore, as a whole, there is an advantage that the straightness of the airflow is improved, the reach of the airflow is extended, and the air conditioning effect is easily spread throughout the room.
　さらに、本実施の形態４では、上吹き時および水平吹き時には、吹出口が本体の上面にのみ開口し前面には開口していないので、本体内部の機能部品から生じる騒音（例えば貫流ファンの駆動モータ音、貫流ファンの風切音、熱交換器内の冷媒流通音）が前方に向けて直接漏れることが抑制されており、意匠的な条件に制約されない羽根による風向制御性の向上と、騒音抑制との両立が図られている。また、上述したように第２羽根が本体外にせり出し第１羽根と直列的に並ぶので、吹出口を本体の上面だけ開口させた状態でも、
好適な水平吹きが可能であり、騒音抑制と快適性との両立も図ることができる。また、本実施の形態４の床置きタイプによれば、上吹き、水平吹き、下吹きが可能であり、吹出範囲が広い空気調和機能を提供することができる。 Further, in the fourth embodiment, when the top blow and the horizontal blow are performed, the blow-out opening is opened only on the upper surface of the main body and is not opened on the front surface. Motor noise, wind noise of cross-flow fan, refrigerant circulation sound in heat exchanger) are prevented from leaking directly forward, improving wind direction controllability by blades not restricted by design conditions, and noise Coexistence with suppression is achieved. In addition, as described above, since the second blade protrudes outside the main body and is arranged in series with the first blade, even in a state where only the upper surface of the main body is opened,
Suitable horizontal blowing is possible, and it is possible to achieve both noise suppression and comfort. In addition, according to the floor-standing type of the fourth embodiment, it is possible to perform top blowing, horizontal blowing, and bottom blowing, and to provide an air conditioning function with a wide blowing range.
