The indoor heat exchanger 13 includes a plurality of fins and a plurality of heat transfer tubes that penetrate the plurality of fins. The indoor heat exchanger 13 is attached to the bottom frame 16 inside the casing 11. The indoor heat exchanger 13 functions as an evaporator or a condenser according to the operating state of the air conditioning indoor unit 10, and exchanges heat between the refrigerant flowing in the heat transfer tube and the air passing through the indoor heat exchanger 13. Let it be done.
　室内熱交換器１３は、図２に示されているように、側面視において両端が下方に向いて屈曲する略逆Ｖ字型の形状を有している。そして、室内熱交換器１３は、上から室内ファン１４を囲い込むように配置されている。 As shown in FIG. 2, the indoor heat exchanger 13 has a substantially inverted V shape in which both ends are bent downward in a side view. And the indoor heat exchanger 13 is arrange | positioned so that the indoor fan 14 may be enclosed from the top.
　（２－４）室内ファン１４
　室内ファン１４は、図２に示されているように、ケーシング１１の内部の略中央部分に位置している。この室内ファン１４は、空調室内機１０の長手方向（左右方向）に細長い略円筒形状をしたクロスフローファンである。室内ファン１４が回転駆動されることによって、室内空気が天面吸込口２５及び底面吸込口２６それぞれから吸い込まれてエアフィルタ１２を通過した後に、室内熱交換器１３を通過することで生成された調和空気が吹出口２７から室内へと吹出される。 (2-4) Indoor fan 14
As shown in FIG. 2, the indoor fan 14 is located at a substantially central portion inside the casing 11. This indoor fan 14 is a cross flow fan having a substantially cylindrical shape elongated in the longitudinal direction (left-right direction) of the air conditioning indoor unit 10. When the indoor fan 14 is driven to rotate, the indoor air is sucked from the top surface suction port 25 and the bottom surface suction port 26, passes through the air filter 12, and then passes through the indoor heat exchanger 13. The conditioned air is blown out from the outlet 27 into the room.
　（２－５）底フレーム１６
　底フレーム１６は、上述のエアフィルタ１２と室内熱交換器１３と室内ファン１４を支える役割を果たす。また、底フレーム１６によって、吸込流路１６ａ及びスクロール空気吹出流路１６ｂが形成される。スクロール空気吹出流路１６ｂは、室内ファン１４の直下から前方斜め下に向かって延びている。このスクロール空気吹出流路１６ｂは、流路上面１６ｃと流路下面１６ｄとの間に挟まれた空間である。 (2-5) Bottom frame 16
The bottom frame 16 serves to support the air filter 12, the indoor heat exchanger 13, and the indoor fan 14 described above. Further, the bottom frame 16 forms a suction channel 16a and a scroll air outlet channel 16b. The scroll air blowing flow passage 16b extends obliquely downward from the front of the indoor fan 14 to the front. The scroll air outlet channel 16b is a space sandwiched between the channel upper surface 16c and the channel lower surface 16d.
　図４には、図２から第２補助フラップ３０、第１補助フラップ４０及び風向調整部材５０が取り除かれた状態が示されている。この図４を用いて、スクロール空気吹出流路１６ｂの形状について説明する。流路下面１６ｄは、吹出口２７の下縁２７ｂから上方に延びており、室内ファン１４の後部斜め上まで覆っている。この流路下面１６ｄは、後方に膨らむように滑らかに湾曲している。左右方向に対して垂直な平面で流路下面１６ｄを切断したときの流路下面１６ｄの断面形状が渦巻き形状になっている。言い換えれば、このような流路下面１６ｄの断面形状は、旋回するにつれて室内ファン１４の回転中心から遠ざかる曲線である。 FIG. 4 shows a state where the second auxiliary flap 30, the first auxiliary flap 40, and the wind direction adjusting member 50 are removed from FIG. The shape of the scroll air blowing channel 16b will be described with reference to FIG. The flow path lower surface 16 d extends upward from the lower edge 27 b of the air outlet 27 and covers the rear portion of the indoor fan 14 obliquely upward. The flow path lower surface 16d is smoothly curved so as to swell rearward. The cross-sectional shape of the flow path lower surface 16d when the flow path lower surface 16d is cut along a plane perpendicular to the left-right direction is a spiral shape. In other words, the cross-sectional shape of such a flow path lower surface 16d is a curve that moves away from the rotation center of the indoor fan 14 as it turns.
　吹出口２７の上縁２７ａと流路上面１６ｃの上面前端１６ｆとの間には、左右に長く延びる凹み１６ｇが形成されている。この凹み１６ｇが形成されることにより、流路上面１６ｃの上面前端１６ｆの前に段差が形成されている。この凹み１６ｇには、第２補助フラップ３０を収納することができる。凹み１６ｇに第２補助フラップ３０が収納された状態では、第２補助フラップ下面３２の後端部が流路上面１６ｃと面一になるように構成されている。流路上面１６ｃは、室内ファン１４の下方に向かって、上面前端１６ｆから後方斜め上にほぼ真っ直ぐに延びている。 Between the upper edge 27a of the blower outlet 27 and the upper surface front end 16f of the flow path upper surface 16c, a recess 16g extending in the left and right direction is formed. By forming the recess 16g, a step is formed in front of the upper surface front end 16f of the flow path upper surface 16c. The second auxiliary flap 30 can be accommodated in the recess 16g. In a state where the second auxiliary flap 30 is housed in the recess 16g, the rear end portion of the second auxiliary flap lower surface 32 is configured to be flush with the flow path upper surface 16c. The flow path upper surface 16c extends substantially straightly rearward and obliquely upward from the upper surface front end 16f toward the lower side of the indoor fan 14.
　（２－６）エアフィルタ１２
　エアフィルタ１２は、天面吸込口２５及び底面吸込口２６から吸い込まれた室内空気中の塵埃を捕集するためのものである。エアフィルタ１２がケーシング１１に装着された状態で、エアフィルタ１２は、ケーシング１１の天面部１１ａと室内熱交換器１３との間に位置する。このエアフィルタ１２が、室内熱交換器１３の表面に室内空気中の塵埃が付着することを防いでいる。エアフィルタ１２は、メンテナンスのために、ケーシング１１に取り付けたり、ケーシング１１から取り出したりすることができるようになっている。 (2-6) Air filter 12
The air filter 12 is for collecting dust in the indoor air sucked from the top surface suction port 25 and the bottom surface suction port 26. With the air filter 12 mounted on the casing 11, the air filter 12 is positioned between the top surface portion 11 a of the casing 11 and the indoor heat exchanger 13. The air filter 12 prevents dust in the room air from adhering to the surface of the indoor heat exchanger 13. The air filter 12 can be attached to the casing 11 or removed from the casing 11 for maintenance.
　（３）上下方向の風向調整
　（３－１）第１風向
　図１及び図２に示されている第２補助フラップ３０と第１補助フラップ４０と風向調整部材５０の姿勢は、第１風向で空気を吹出すときにとられる。第１風向は、室内空間ＲＳの奥まで気流を循環させるときの風向である。室内空間ＲＳの奥まで気流を循環させるためには、吹出口２７で拡散させずに、速い風速を持つ層流を作り出すことが好ましい。このような層流を作り出すには、スクロール空気吹出流路１６ｂを延長することが好ましい。しかし、スクロール空気吹出流路１６ｂを延ばしたり縮めたりすることが難しいので、第２補助フラップ３０と風向調整部材５０の姿勢により、スクロール空気吹出流路１６ｂを延長したのと同じ状況を擬似的につくっているのが図１及び図２の状態である。 (3) Vertical wind direction adjustment (3-1) First wind direction The posture of the second auxiliary flap 30, the first auxiliary flap 40, and the wind direction adjusting member 50 shown in FIGS. 1 and 2 is the first wind direction. Taken when blowing air. The first wind direction is the wind direction when the airflow is circulated to the back of the indoor space RS. In order to circulate the airflow to the interior of the indoor space RS, it is preferable to create a laminar flow having a high wind speed without being diffused at the air outlet 27. In order to create such a laminar flow, it is preferable to extend the scroll air blowing channel 16b. However, since it is difficult to extend or contract the scroll air blowing flow path 16b, the same situation as the case where the scroll air blowing flow path 16b is extended is simulated by the posture of the second auxiliary flap 30 and the wind direction adjusting member 50. The state shown in FIGS. 1 and 2 is created.
　第１風向では、第２補助フラップ３０は、第２補助フラップ下面３２がスクロール空気吹出流路１６ｂの流路上面１６ｃを前側に延長する姿勢をとっている。また、この第１風向では、風向調整部材５０は、風向調整部材上面５１がスクロール空気吹出流路１６ｂの流路下面１６ｄを前側に延長する姿勢をとっている。 In the first wind direction, the second auxiliary flap 30 has a posture in which the second auxiliary flap lower surface 32 extends the flow channel upper surface 16c of the scroll air blowing flow channel 16b forward. Further, in this first wind direction, the wind direction adjusting member 50 takes a posture in which the wind direction adjusting member upper surface 51 extends the flow path lower surface 16d of the scroll air blowing flow path 16b forward.
　図４に示されているように、流路上面１６ｃを前側に延長すると、流路上面１６ｃとほぼ平行に上面前端１６ｆから始まる第１仮想面ＰＬ１が形成される。この場合、後方向及び上下方向に平行な断面で第１仮想面ＰＬ１を切断してできる第１仮想線が、スクロール空気吹出流路１６ｂの流路上面１６ｃの先端部の接線に一致することが好ましい。また、流路下面１６ｄを前側に延長すると、流路下面１６ｄの下面前端１６ｈとほぼ平行に下面前端１６ｈから始まる第２仮想面ＰＬ２が形成される。この場合、前後方向及び上下方向に平行な断面で第２仮想面ＰＬ２を切断してできる第２仮想線がスクロール空気吹出流路１６ｂの流路下面１６ｄの先端部の接線に一致することが好ましい。 As shown in FIG. 4, when the flow path upper surface 16c is extended to the front side, a first virtual plane PL1 starting from the upper surface front end 16f is formed substantially parallel to the flow path upper surface 16c. In this case, the first imaginary line formed by cutting the first imaginary plane PL1 in a cross section parallel to the rear direction and the up-down direction may coincide with the tangent of the tip of the flow channel upper surface 16c of the scroll air blowing flow channel 16b. preferable. Further, when the flow path lower surface 16d is extended to the front side, a second virtual surface PL2 starting from the lower surface front end 16h is formed substantially parallel to the lower surface front end 16h of the flow path lower surface 16d. In this case, it is preferable that the second imaginary line formed by cutting the second imaginary plane PL2 in a cross section parallel to the front-rear direction and the up-down direction coincides with the tangent of the tip end portion of the flow path lower surface 16d of the scroll air blowing flow path 16b. .
　なお、第２補助フラップ下面３２が多少湾曲する場合もあるが、その場合には、第２補助フラップ下面３２の主面の後端部が第１仮想面ＰＬ１に一致することをもって、第２補助フラップ下面３２が第１仮想面ＰＬ１に一致しているとみなす。また、第２補助フラップ下面３２が多少湾曲する場合もあるが、その場合には、風向調整部材上面５１の主面の後端部が第２仮想面ＰＬ２に一致することをもって、風向調整部材上面５１が第２仮想面ＰＬ２に一致しているとみなす。なお、ここで主面とは、風向調整には寄与しない部分を除く、専ら風向調整に用いられる面をいう。例えば、凹部５４は、ケーシング１１にある出っ張りに対応して設けられたものである。この凹部５４の部分は、風向調整部材５０で吹出口２７を閉じる際にケーシング１１の出っ張りが邪魔にならないようにするための構造であり、風向調整にはあまり寄与していないことから、主面には含まれない。 In addition, the second auxiliary flap lower surface 32 may be slightly curved. In this case, the second auxiliary flap lower surface 32 has the rear end portion of the main surface coinciding with the first virtual surface PL1. It is assumed that the flap lower surface 32 matches the first virtual surface PL1. In addition, the second auxiliary flap lower surface 32 may be slightly curved. In this case, the rear end portion of the main surface of the wind direction adjusting member upper surface 51 coincides with the second virtual surface PL2, so that the wind direction adjusting member upper surface is aligned. 51 is considered to coincide with the second virtual plane PL2. Here, the main surface refers to a surface used exclusively for wind direction adjustment, excluding portions that do not contribute to wind direction adjustment. For example, the recessed part 54 is provided corresponding to the protrusion in the casing 11. The concave portion 54 is a structure for preventing the protrusion of the casing 11 from obstructing when the air outlet 27 is closed by the air direction adjusting member 50, and does not contribute much to the air direction adjustment. Is not included.
　第２補助フラップ３０は、回動するために、流路上面１６ｃの上面前端１６ｆから離して取り付けられている。同様の理由から、風向調整部材５０も流路下面１６ｄの下面前端１６ｈから離して取り付けられている。しかし、第２補助フラップ３０と流路上面１６ｃ及び風向調整部材５０と流路下面１６ｄが離れ過ぎていると、第２補助フラップ下面３２及び風向調整部材５０によるスクロール空気吹出流路１６ｂの十分な延長効果が得られない。そこで、第１風向に設定されている状態において、第２補助フラップ３０が回動可能である範囲において第２補助フラップ３０の後端３４（図２参照）から流路上面１６ｃの上面前端１６ｆまでの距離が５ｍｍ以下になるように構成され、風向調整部材５０の後端５６から流路下面１６ｄの下面前端１６ｈまでの距離Ｌ１が５ｍｍ以下になるように構成されている（図５参照）
　第１補助フラップ４０は、第２補助フラップ３０の下流側に設けられていることから、延長されたスクロール空気吹出流路１６ｂの吹出口である第２補助フラップ３０の前端３３と風向調整部材５０の前端５５とで囲まれた部分から吹出される空気の風向きを上下に微調整する。図２に示されている状態では、第１補助フラップ４０が、吹出される空気に対して抵抗ができるだけ低くなる姿勢をとりながら、水平よりも少し下を向いたスクロール空気吹出流路１６ｂから吹出される空気の風向きを少し上に持ち上げる姿勢をとっている。 The second auxiliary flap 30 is mounted apart from the upper surface front end 16f of the flow channel upper surface 16c in order to rotate. For the same reason, the wind direction adjusting member 50 is also mounted apart from the lower surface front end 16h of the flow path lower surface 16d. However, if the second auxiliary flap 30 and the flow path upper surface 16c and the wind direction adjusting member 50 and the flow path lower surface 16d are separated too much, the scroll air blowing flow path 16b by the second auxiliary flap lower surface 32 and the wind direction adjusting member 50 is sufficient. The extension effect cannot be obtained. Therefore, from the rear end 34 (see FIG. 2) of the second auxiliary flap 30 to the upper front end 16f of the flow path upper surface 16c in a range in which the second auxiliary flap 30 can be rotated in the state where the first wind direction is set. The distance L1 from the rear end 56 of the airflow direction adjusting member 50 to the lower surface front end 16h of the flow path lower surface 16d is configured to be 5 mm or less (see FIG. 5).
Since the first auxiliary flap 40 is provided on the downstream side of the second auxiliary flap 30, the front end 33 of the second auxiliary flap 30 that is the outlet of the extended scroll air blowing passage 16 b and the airflow direction adjusting member 50. The wind direction of the air blown out from the portion surrounded by the front end 55 is finely adjusted up and down. In the state shown in FIG. 2, the first auxiliary flap 40 is blown out from the scroll air blowing passage 16 b facing slightly downward from the horizontal while taking a posture in which the resistance to the blown air becomes as low as possible. It takes the posture that lifts the wind direction of the air slightly.
　（３－２）第２風向
　図６に示されている第２風向は、空調室内機１０の後面部１１ｃが取り付けられている壁に沿う気流をつくりだすときの風向である。第２風向で空気を吹出すように設定された第２補助フラップ３０、第１補助フラップ４０及び風向調整部材５０は、吹出口２７よりも後面部１１ｃの方向に向かう気流を生成する。このとき、風向調整部材５０は、風向調整部材上面５１が前後方向に対して垂直な鉛直面よりも後方に回動して、前端５５が後端５６よりも後方に位置している。同様に、第１補助フラップ４０も、第１補助フラップ上面４１が前後方向に対して垂直な鉛直面よりも後方に回動して、前端４３が後端４４（図２参照）よりも後方に位置している。同様に、第２補助フラップ３０も、第２補助フラップ上面３１が前後方向に対して垂直な鉛直面よりも後方に回動して、前端３３が後端３４（図２参照）よりも後方に位置している。 (3-2) Second Wind Direction The second wind direction shown in FIG. 6 is the wind direction when airflow is generated along the wall to which the rear surface portion 11c of the air conditioning indoor unit 10 is attached. The second auxiliary flap 30, the first auxiliary flap 40, and the wind direction adjusting member 50 that are set so as to blow out air in the second wind direction generate an air flow that goes in the direction of the rear surface portion 11 c from the air outlet 27. At this time, in the wind direction adjusting member 50, the wind direction adjusting member upper surface 51 rotates rearward from the vertical plane perpendicular to the front-rear direction, and the front end 55 is positioned rearward of the rear end 56. Similarly, in the first auxiliary flap 40, the first auxiliary flap upper surface 41 rotates rearward from the vertical plane perpendicular to the front-rear direction, and the front end 43 is rearward from the rear end 44 (see FIG. 2). positioned. Similarly, in the second auxiliary flap 30, the second auxiliary flap upper surface 31 is rotated rearward from the vertical plane perpendicular to the front-rear direction, and the front end 33 is rearward from the rear end 34 (see FIG. 2). positioned.
　第２風向のときの第２補助フラップ３０と第１補助フラップ４０は、正面視において、第２補助フラップ３０と第１補助フラップ４０が重なる姿勢をとることで、第２補助フラップ３０と第１補助フラップ４０の間の隙間から前方に空気が流れるのを防いでいる。 When the second auxiliary flap 30 and the first auxiliary flap 40 are in the second wind direction, the second auxiliary flap 30 and the first auxiliary flap 40 have the first auxiliary flap 30 and the first auxiliary flap 40 so as to overlap each other when viewed from the front. Air is prevented from flowing forward from the gap between the auxiliary flaps 40.
　第２風向として、図８（ａ）及び図８（ｂ）に示されている姿勢を、第２補助フラップ３０と第１補助フラップ４０がとることもできる。図８（ａ）に示されている第２補助フラップ３０と第１補助フラップ４０は、第１補助フラップ下面４２に第２補助フラップ上面３１が接触する姿勢をとっている。また、図８（ｂ）に示されている第２補助フラップ３０と第１補助フラップ４０は、第２補助フラップ３０の前端３３が第１補助フラップ４０に接近して、第２補助フラップ下面３２と第１補助フラップ下面４２が一列に並んで続いている姿勢をとっている。 As the second wind direction, the second auxiliary flap 30 and the first auxiliary flap 40 can take the posture shown in FIGS. 8A and 8B. The second auxiliary flap 30 and the first auxiliary flap 40 shown in FIG. 8A are in such a posture that the second auxiliary flap upper surface 31 is in contact with the first auxiliary flap lower surface 42. Further, the second auxiliary flap 30 and the first auxiliary flap 40 shown in FIG. 8B are arranged such that the front end 33 of the second auxiliary flap 30 approaches the first auxiliary flap 40 and the second auxiliary flap lower surface 32. And the 1st auxiliary | assistant flap lower surface 42 has taken the attitude | position continued in a line.
　（３－３）第３風向
　図９（ａ）に示されている第３風向は、最大風量で空気を吹出すときの風向である。第３風向で空気を吹出すように設定されたとき、第２補助フラップ３０は、流路上面１６ｃの前にある凹み１６ｇに収納されている。第３風向では、第１補助フラップ４０の前端４３が第１風向のときよりも少し上に移動して、第１補助フラップ４０が吹出口２７から吹出される気流を上に広げる姿勢をとっている。第３風向では、風向調整部材５０の前端５５が第１風向のときよりも少し下に移動して、風向調整部材５０が吹出口２７から吹出される気流を下に広げる姿勢をとっている。つまり、第１補助フラップ４０及び風向調整部材５０は、前方にいくほど広がって、最大風量で吹出された空気を室内空間ＲＳに送り込みやすい姿勢をとっている。 (3-3) Third Wind Direction The third wind direction shown in FIG. 9A is a wind direction when air is blown out at the maximum air volume. When set to blow out air in the third wind direction, the second auxiliary flap 30 is housed in the recess 16g in front of the flow path upper surface 16c. In the third wind direction, the front end 43 of the first auxiliary flap 40 moves slightly higher than in the first wind direction, and the first auxiliary flap 40 takes a posture of expanding the airflow blown out from the outlet 27 upward. Yes. In the third wind direction, the front end 55 of the wind direction adjusting member 50 moves slightly lower than in the first wind direction, and the wind direction adjusting member 50 takes a posture of expanding the air flow blown out from the outlet 27 downward. That is, the 1st auxiliary | assistant flap 40 and the wind direction adjustment member 50 are taking the attitude | position which spreads so that it goes ahead and is easy to send the air blown off with the maximum air volume into indoor space RS.
　（３－４）第４風向
　図９（ｂ）に示されている第４風向は、前方下向きに空気を吹出すときの風向きである。第４風向で空気を吹出すように設定されたとき、第２補助フラップ３０は、流路上面１６ｃの前にある凹み１６ｇに収納されている。第４風向では、第１補助フラップ４０の前端４３が第１風向のときよりも少し下に移動して、第１補助フラップ４０が吹出口２７から吹出される気流を下に押下げる姿勢をとっている。つまり、このときの第１補助フラップ下面４２は、前方に行くほど下に下がる割合が第１仮想面ＰＬ１よりも大きく、第１仮想面ＰＬ１よりも前下がりになっている。第４風向では、風向調整部材５０の前端５５が第１風向のときよりも少し下に移動して、風向調整部材５０が吹出口２７から吹出される気流を下に誘導する姿勢をとっている。つまり、このときの風向調整部材上面５１は、前方に行くほど下に下がる割合が第２仮想面ＰＬ２よりも大きく、第２仮想面ＰＬ２よりも前下がりになっている。 (3-4) Fourth Wind Direction The fourth wind direction shown in FIG. 9B is the wind direction when air is blown forward and downward. When set to blow out air in the fourth wind direction, the second auxiliary flap 30 is accommodated in the recess 16g in front of the flow path upper surface 16c. In the fourth wind direction, the front end 43 of the first auxiliary flap 40 moves slightly lower than that in the first wind direction, and the first auxiliary flap 40 takes a posture of pushing down the airflow blown from the outlet 27. ing. That is, the lower rate of the first auxiliary flap lower surface 42 at this time is lower than the first virtual surface PL1 as it goes forward, and is lower than the first virtual surface PL1. In the fourth wind direction, the front end 55 of the wind direction adjusting member 50 moves slightly lower than in the first wind direction, and the wind direction adjusting member 50 takes a posture of guiding the airflow blown out from the outlet 27 downward. . That is, the wind direction adjusting member upper surface 51 at this time has a rate of lowering downward as it goes forward is larger than the second virtual surface PL2, and is lower than the second virtual surface PL2.
　（３－５）第５風向
　図９（ｃ）に示されている第５風向は、冷房時に、第２補助フラップ３０を使って前方下向きに空気を吹出すときの風向きの一例である。第５風向で空気を吹出すように設定されたとき、第２補助フラップ３０は、前端３３が下に移動するように回動して凹み１６ｇから出て前下がりの姿勢をとっている。このとき、第２補助フラップ下面３２は、流路上面１６ｃと第１補助フラップ下面４２とを結ぶ面に近い位置にあって、流路上面１６ｃから第１補助フラップ下面４２に向かう気流がスムーズになるように、吹出される空気を中継する。 (3-5) Fifth Wind Direction The fifth wind direction shown in FIG. 9C is an example of the wind direction when air is blown forward and downward using the second auxiliary flap 30 during cooling. When set to blow out air in the fifth wind direction, the second auxiliary flap 30 is rotated so that the front end 33 moves downward, and comes out of the recess 16g to take a front-down posture. At this time, the second auxiliary flap lower surface 32 is located close to the surface connecting the flow path upper surface 16c and the first auxiliary flap lower surface 42, and the airflow from the flow channel upper surface 16c to the first auxiliary flap lower surface 42 is smooth. The air that is blown out is relayed.
　第５風向では、第１補助フラップ４０の前端４３が第１風向のときよりも少し下に移動しているものの前端４３が第４風向のときよりも少し上に移動した状態であり、第１補助フラップ４０が吹出口２７から吹出される気流を少し下に押下げる姿勢をとっている。また、第５風向では、風向調整部材５０の姿勢が第４風向と同じである。このような姿勢を第２補助フラップ３０、第１補助フラップ４０及び風向調整部材５０がとることで、吹出された空気を第４風向に比べて前方の遠い場所にまで運ぶことができる。 In the fifth wind direction, the front end 43 of the first auxiliary flap 40 moves slightly lower than in the first wind direction, but the front end 43 moves slightly higher than in the fourth wind direction. The auxiliary flap 40 takes a posture of pushing down the airflow blown out from the air outlet 27 slightly. In the fifth wind direction, the attitude of the wind direction adjusting member 50 is the same as the fourth wind direction. When the second auxiliary flap 30, the first auxiliary flap 40, and the wind direction adjusting member 50 take such a posture, it is possible to carry the blown air to a far place ahead of the fourth wind direction.
　（３－６）第１補助フラップ４０、第２補助フラップ３０及び風向調整部材５０の移動
　図６、図７、図８（ａ）及び図８（ｂ）に示されている第２補助フラップ３０の前端３３の位置は、第１補助フラップ４０の回転中心４５よりも下にある状態である。それに対して、凹み１６ｇに収納されているとき第２補助フラップ３０の位置は、第１補助フラップ４０の回転中心４５よりも上にある状態である。図６から図８（ｂ）に示されている第２補助フラップ３０の位置に第２補助フラップ３０が回動してくるには、第２補助フラップ３０が回動する軌道上にある図６から図８（ｂ）の位置にある第１補助フラップ４０が邪魔になる。つまり、凹み１６ｇに第２補助フラップ３０が収納されているときに、図６から図８（ｂ）に示されている位置に第１補助フラップ４０があったのでは、第１補助フラップ４０に当たってしまって第２補助フラップ３０が図６から図８（ｂ）に示されている位置にまで回動することができない。そこで、例えば、第１補助フラップ４０がケーシング１１に最も近くなるように前方に回動した状態、言い換えるとケーシング１１に第１補助フラップ４０が沿う状態で、先に凹み１６ｇに収納されている第２補助フラップ３０を図６から図８（ｂ）に示されている位置まで後方に回動させる。続いて、第１補助フラップ４０を図６から図８（ｂ）に示されている位置まで後方に回動させる。このように第２補助フラップ３０と第１補助フラップ４０が互いに干渉を避ける回動動作を行うことにより、第２補助フラップ３０の前端３３が第１補助フラップ４０の回転中心４５よりも上にある状態と下にある状態とを入れ換えることができる。 (3-6) Movement of first auxiliary flap 40, second auxiliary flap 30 and wind direction adjusting member 50 Second auxiliary flap 30 shown in FIGS. 6, 7, 8 (a) and 8 (b) The position of the front end 33 is lower than the rotation center 45 of the first auxiliary flap 40. On the other hand, the second auxiliary flap 30 is positioned above the rotation center 45 of the first auxiliary flap 40 when stored in the recess 16g. In order for the second auxiliary flap 30 to turn to the position of the second auxiliary flap 30 shown in FIG. 6 to FIG. 8B, the second auxiliary flap 30 is on the orbit along which the second auxiliary flap 30 rotates. The first auxiliary flap 40 at the position shown in FIG. That is, when the second auxiliary flap 30 is housed in the recess 16g, the first auxiliary flap 40 hits the first auxiliary flap 40 if the first auxiliary flap 40 is in the position shown in FIGS. 6 to 8B. The second auxiliary flap 30 cannot rotate to the position shown in FIG. 6 to FIG. 8B. Therefore, for example, the first auxiliary flap 40 is stored in the recess 16g first in a state where the first auxiliary flap 40 is rotated forward so as to be closest to the casing 11, in other words, in a state where the first auxiliary flap 40 is along the casing 11. 2 The auxiliary flap 30 is rotated backward from the position shown in FIG. 6 to the position shown in FIG. Then, the 1st auxiliary | assistant flap 40 is rotated back to the position shown by FIG. 6B from FIG. In this way, the second auxiliary flap 30 and the first auxiliary flap 40 perform a pivoting operation to avoid mutual interference, so that the front end 33 of the second auxiliary flap 30 is above the rotation center 45 of the first auxiliary flap 40. The state and the underlying state can be interchanged.
　（４）風向調整部材の構造
　図１０（ａ）には、図３のＩ－Ｉ線で切断した風向調整部材５０の端面が示されている。図１０（ｂ）には、右側から見た風向調整部材５０の側面が示されている。図１１には、風向調整部材５０の中央部分で破断して右上方から見た状態が示されている。風向調整部材５０は、風向調整部材上面５１を構成する板状部材と風向調整部材下面５２を構成する板状部材が融着された中空構造を有している。中空構造であるために、風向調整部材上面５１及び風向調整部材下面５２で応力の集中が起きると、風向調整部材５０の変形の原因になる。風向調整部材５０が変形すると、例えば、運転停止時に風向調整部材５０とケーシング１１の間に大きな隙間ができて見栄えが悪くなる。 (4) Structure of Wind Direction Adjusting Member FIG. 10A shows an end surface of the wind direction adjusting member 50 cut along the line II in FIG. FIG. 10B shows a side surface of the wind direction adjusting member 50 as viewed from the right side. FIG. 11 shows a state in which the wind direction adjusting member 50 is broken at the center and viewed from the upper right. The wind direction adjusting member 50 has a hollow structure in which a plate-like member constituting the wind direction adjusting member upper surface 51 and a plate-like member constituting the wind direction adjusting member lower surface 52 are fused. Due to the hollow structure, if the stress concentration occurs on the wind direction adjusting member upper surface 51 and the wind direction adjusting member lower surface 52, the wind direction adjusting member 50 may be deformed. When the wind direction adjusting member 50 is deformed, for example, a large gap is formed between the wind direction adjusting member 50 and the casing 11 when the operation is stopped, and the appearance is deteriorated.
　このような応力の集中を防ぐために、風向調整部材５０の中央軸支部分の凹部６０に被支持部５３が設けられている。図１２に示されているように、ケーシング１１の吹出口２７の上縁２７ａと下縁２７ｂの間に架け渡された支持部７１によって中央軸支部分の被支持部５３が回動可能に支持されている。また、風向調整部材５０の右端部６１及び左端部６２（図３参照）には、風向調整部材５０の厚みよりも幅のあるフランジ５９が取り付けられている。そして、これらフランジ５９に被支持部５３が設けられている。これらフランジ５９の被支持部５３は、ケーシング１１に設けられている支持部（図示せず）に回動可能に嵌めこまれる。 In order to prevent such concentration of stress, a supported portion 53 is provided in the concave portion 60 of the central shaft support portion of the wind direction adjusting member 50. As shown in FIG. 12, the supported portion 53 of the central shaft support portion is rotatably supported by the support portion 71 spanned between the upper edge 27 a and the lower edge 27 b of the air outlet 27 of the casing 11. Has been. A flange 59 having a width wider than the thickness of the wind direction adjusting member 50 is attached to the right end portion 61 and the left end portion 62 (see FIG. 3) of the wind direction adjusting member 50. These flanges 59 are provided with supported portions 53. The supported portions 53 of the flanges 59 are rotatably fitted to support portions (not shown) provided in the casing 11.
　次に、風向調整部材５０に設けられている窪み部５７について説明する前に、風向調整部材５０の姿勢と気流の関係について説明する。空調室内機１０は、図１３（ａ）に示されているように、例えば第２風向のときに設置側壁ＷＬに沿う気流を生じさせるが、このような気流を第１気流ＣＬ１と呼ぶ。第１気流ＣＬ１が生じているときには、風向調整部材上面５１が鉛直面に対して後方に回動して、風向調整部材５０の前端５５が後端５６よりも後方に位置した姿勢をとるが、このような姿勢を第１姿勢と呼ぶ。 Next, before describing the recess 57 provided in the wind direction adjusting member 50, the relationship between the attitude of the wind direction adjusting member 50 and the airflow will be described. As shown in FIG. 13A, the air conditioning indoor unit 10 generates an air flow along the installation side wall WL when the air flow is in the second wind direction, for example, and such an air flow is referred to as a first air flow CL1. When the first airflow CL1 is generated, the wind direction adjusting member upper surface 51 rotates rearward with respect to the vertical surface, and the front end 55 of the wind direction adjusting member 50 is positioned behind the rear end 56. Such a posture is called a first posture.
　また、図１３（ｂ）に示されているように、例えば第１風向、第３風向又は第５風向のときに、吹出口２７よりも前に向かう気流を生じさせるが、このような気流を第２気流ＣＬ２と呼ぶ。このような第２気流ＣＬ２が生じているとき、風向調整部材５０は、風向調整部材上面５１が鉛直面に対して前方に回動して、風向調整部材５０の前端５５が後端５６よりも前側に位置した姿勢をとるが、このような姿勢を第２姿勢と呼ぶ。 Further, as shown in FIG. 13 (b), for example, when the first wind direction, the third wind direction, or the fifth wind direction is generated, an air flow directed forward from the outlet 27 is generated. This is called the second air flow CL2. When such second airflow CL2 is generated, the wind direction adjusting member 50 rotates the wind direction adjusting member upper surface 51 forward with respect to the vertical surface, and the front end 55 of the wind direction adjusting member 50 is more than the rear end 56. The posture positioned on the front side is taken, and such a posture is referred to as a second posture.
　図１４には、風向調整部材５０が第１姿勢をとっている状態の吹出口２７の下縁２７ｂの周囲が拡大して示されている。窪み部５７は、風向調整部材下面５２の段差で形成されている。左右方向に対して垂直な面で風向調整部材５０を切断した断面形状において、風向調整部材下面５２の前側が下に凸の曲線を描くのに対し、後側が上に凸の曲線を描いている。このような風向調整部材下面５２の構造により、風向調整部材下面５２の上に凸の曲線を描く後側が上に窪んで段差を形成しており、この上に凹んだ段差部分が窪み部５７である。 FIG. 14 shows an enlarged view of the periphery of the lower edge 27b of the air outlet 27 in a state where the air direction adjusting member 50 is in the first posture. The recess 57 is formed by a step on the lower surface 52 of the wind direction adjusting member. In a cross-sectional shape in which the wind direction adjusting member 50 is cut along a plane perpendicular to the left-right direction, the front side of the wind direction adjusting member lower surface 52 has a downwardly convex curve, whereas the rear side has an upwardly convex curve. . Due to such a structure of the wind direction adjusting member lower surface 52, the rear side of the convex curve on the wind direction adjusting member lower surface 52 is recessed upward to form a step, and the recessed step portion is the recessed portion 57. is there.
　第１姿勢をとっている第２風向のときに、風向調整部材下面５２に形成されている窪み部５７に吹出口２７の下縁２７ｂが入り込むように、風向調整部材５０が取り付けられている。従って、風向調整部材下面５２に窪み部５７がない場合に比べて、窪み部５７に下縁２７ｂが入り込む分だけ、風向調整部材５０の前端５５をより後に移動させることができる。その結果、窪み部５７がない場合に比べて窪み部５７があることにより、より高い位置から設置側壁ＷＬに気流を沿わせることができる。 The wind direction adjusting member 50 is attached so that the lower edge 27b of the air outlet 27 enters the recess 57 formed in the lower surface 52 of the wind direction adjusting member 52 when the second wind direction is in the first posture. Accordingly, the front end 55 of the airflow direction adjusting member 50 can be moved further by the amount of the lower edge 27b entering the indented portion 57 as compared with the case where the indented portion 57 is not provided on the airflow direction adjusting member lower surface 52. As a result, the presence of the recess 57 compared to the case where the recess 57 is not present allows the air flow to follow the installation side wall WL from a higher position.
　（５）吹出口２７の下縁２７ｂの構造
　図１４に示されているように、下縁２７ｂには、後方に後退した後退部７２が形成され、後方に凹んだ溝部７３が形成されている。下縁２７ｂを真っ直ぐ鉛直に切り落としたような形状にしたり、下縁２７ｂの形状を下方に行くに従って前方に突き出たように形成したりする場合に比べて、後退部７２が形成されることで、風向調整部材５０の前端５５をより後方に移動させることができる。言い換えれば、風向調整部材上面５１が鉛直面に対して後方に回動した姿勢をとることができるということである。その結果、第２風向において、風向調整部材５０が、後退部７２が形成されない場合に比べて、より高い位置から設置側壁ＷＬに気流を沿わせる第１姿勢をとることができる。 (5) Structure of the lower edge 27b of the air outlet 27 As shown in FIG. 14, the lower edge 27b is formed with a receding portion 72 that is retracted rearward and a groove portion 73 that is recessed rearward. . Compared to the case where the lower edge 27b is cut straight and vertically, or the lower edge 27b is formed to protrude forward as it goes downward, the receding portion 72 is formed. The front end 55 of the wind direction adjusting member 50 can be moved further rearward. In other words, it is possible to take a posture in which the wind direction adjusting member upper surface 51 is rotated backward with respect to the vertical surface. As a result, in the second wind direction, the wind direction adjusting member 50 can take a first posture in which the airflow is made to flow along the installation side wall WL from a higher position than when the receding portion 72 is not formed.
　第１姿勢をとったときに、下縁２７ｂと風向調整部材下面５２との間には、隙間ができる。この隙間に冷風が流れると、環境条件によっては、下縁２７ｂ及び風向調整部材５０に結露が生じることがある。溝部７３は、この隙間に生じる気流を乱す役割を果たす。隙間に生じる気流が乱されて空気がかき混ぜられることにより、結露が生じ難くなる。 When the first posture is taken, a gap is formed between the lower edge 27b and the wind direction adjusting member lower surface 52. When cold air flows through this gap, condensation may occur on the lower edge 27b and the wind direction adjusting member 50 depending on environmental conditions. The groove part 73 plays the role which disturbs the airflow which arises in this clearance gap. Condensation is less likely to occur when the airflow generated in the gap is disturbed and the air is agitated.
　（６）変形例
　（６－１）変形例Ａ
　上記実施形態では、風向調整部材下面５２に窪み部５７が段差で形成されている場合について説明したが、図１５及び図１６に示されている風向調整部材５０Ａの傾斜端面５７Ａのように、窪み部を傾斜端面５７Ａで形成することもできる。左右方向に対して垂直な面で風向調整部材５０Ａを切断した断面形状において、風向調整部材下面５２Ａの前側が下に凸の緩やかな曲線を描くのに対し、後側が傾斜の大きな直線を描いている。このような風向調整部材下面５２Ａの構造によって、風向調整部材下面５２Ａの後側に窪み部が傾斜端面５７Ａにより形成されている。 (6) Modification (6-1) Modification A
In the above embodiment, the case where the recess 57 is formed in a step on the lower surface 52 of the wind direction adjusting member has been described. However, the recess is formed like the inclined end surface 57A of the wind direction adjusting member 50A shown in FIGS. The part can also be formed by the inclined end face 57A. In a cross-sectional shape obtained by cutting the airflow direction adjusting member 50A along a plane perpendicular to the left-right direction, the front side of the airflow direction adjusting member lower surface 52A draws a gentle curve that protrudes downward, whereas the rear side draws a straight line with a large slope. Yes. With such a structure of the wind direction adjusting member lower surface 52A, a recess is formed by the inclined end surface 57A on the rear side of the wind direction adjusting member lower surface 52A.
　風向調整部材５０Ａが第１姿勢をとるときに、この窪み部としての傾斜端面５７Ａに対向する吹出口２７の下縁２７ｂにも傾斜端面７４が形成されている。窪み部としての傾斜端面５７Ａと下縁２７ｂの傾斜端面７４とは、風向調整部材５０Ａが後方に回動して前端５５が最大限後方に移動したときに、互いに平行になるように構成されることが好ましい。なお、この下縁２７ｂの傾斜端面には、上記実施形態で説明した溝部７３が形成されてもよい。 When the wind direction adjusting member 50A takes the first posture, the inclined end surface 74 is also formed on the lower edge 27b of the air outlet 27 facing the inclined end surface 57A as the recess. The inclined end surface 57A as the recess and the inclined end surface 74 of the lower edge 27b are configured to be parallel to each other when the wind direction adjusting member 50A rotates rearward and the front end 55 moves rearward as much as possible. It is preferable. In addition, the groove part 73 demonstrated in the said embodiment may be formed in the inclination end surface of this lower edge 27b.
　（７）特徴
　（７－１）
　本実施形態の壁掛け式の空調室内機１０によれば、風向調整部材５０，５０Ａが第１姿勢をとるときに風向調整部材５０，５０Ａの窪み部５７、窪み部としての傾斜端面５７Ａの窪んだところに吹出口２７の下縁２７ｂが入り込む。例えば、図１０及び図１６に示されている二点鎖線と風向調整部材下面５２，５２Ａとで囲まれた空間が窪み部５７、窪み部としての傾斜端面５７Ａの窪んだところである。窪み部５７、窪み部としての傾斜端面５７Ａの窪んだところに下縁２７ｂが入り込むことにより、回動動作の範囲を増やすことができることから、快適性の確保のための気流制御の制限を緩和することができる。また、空調室内機１０では、風向調整部材下面５２，５２Ａにおいて窪み部５７、窪み部としての傾斜端面５７Ａが目立ち難く形成されているので、意匠性を良好に保つことができている。なお、二点鎖線で示された平面は、例えば、窪み部５７、窪み部としての傾斜端面５７Ａの前後の平面を延長して形成されている。 (7) Features (7-1)
According to the wall-mounted air conditioning indoor unit 10 of the present embodiment, when the wind direction adjusting members 50, 50A take the first posture, the recessed portions 57 of the wind direction adjusting members 50, 50A and the inclined end surface 57A as the recessed portions are recessed. However, the lower edge 27b of the air outlet 27 enters. For example, the space surrounded by the two-dot chain line and the wind direction adjusting member lower surfaces 52 and 52A shown in FIGS. 10 and 16 is the recessed portion 57 and the inclined end surface 57A as the recessed portion. Since the lower edge 27b enters the recessed portion of the recessed portion 57 and the inclined end surface 57A as the recessed portion, the range of the rotational operation can be increased, so that the restriction on the air flow control for ensuring comfort is eased. be able to. Further, in the air conditioner indoor unit 10, the recess 57 and the inclined end surface 57 </ b> A as the recess are formed in the wind direction adjusting member lower surfaces 52 and 52 </ b> A so as not to be conspicuous. In addition, the plane shown with the dashed-two dotted line is formed, for example, extending the flat part before and behind 57 A of inclination end surfaces as a hollow part 57 and a hollow part.

　図１４に示されているように、空調室内機１０のケーシング１１は、吹出口２７の下縁２７ｂであって且つ第１姿勢をとった風向調整部材５０の風向調整部材下面５２の後端部に対向する位置に、風向調整部材下面５２の形状に対応する後退部７２が形成されている。この後退部７２が風向調整部材下面５２の形状に対応して設けられていることから、後退部７２が設けられていない場合に比べて風向調整部材５０の後側への回動範囲を大きくすることができる。その結果、回動範囲が大きくなる分だけ空調室内機１０の気流制御の制限を緩和することができる。 (7-2)
As shown in FIG. 14, the casing 11 of the air conditioning indoor unit 10 is the lower end 27 b of the air outlet 27 and the rear end portion of the airflow direction adjustment member lower surface 52 of the airflow direction adjustment member 50 in the first posture. A retreating portion 72 corresponding to the shape of the airflow direction adjusting member lower surface 52 is formed at a position facing the front surface. Since the retreating portion 72 is provided corresponding to the shape of the airflow direction adjusting member lower surface 52, the rotation range to the rear side of the airflow direction adjusting member 50 is increased as compared with the case where the retreating portion 72 is not provided. be able to. As a result, the restriction on the air flow control of the air conditioning indoor unit 10 can be relaxed by the amount that the rotation range is increased.
　（７－３）
　図１４に示されているように、ケーシング１１の吹出口２７の下縁２７ｂに設けられた溝部７３が、風向調整部材５０とケーシング１１との間の隙間に対向して形成されている。その結果、風向調整部材５０とケーシング１１の隙間を流れる気流を攪拌することができ、溝部７３によって、風向調整部材５０とケーシング１１との間にできる隙間で結露が発生するのを抑制することができる。 (7-3)
As shown in FIG. 14, a groove 73 provided on the lower edge 27 b of the air outlet 27 of the casing 11 is formed to face the gap between the wind direction adjusting member 50 and the casing 11. As a result, the airflow flowing through the gap between the wind direction adjusting member 50 and the casing 11 can be agitated, and the groove 73 can suppress the occurrence of condensation in the gap formed between the wind direction adjusting member 50 and the casing 11. it can.
　（７－４）
　図１５及び図１６に示されているように、風向調整部材５０Ａの窪み部としての傾斜端面５７Ａとケーシング１１の傾斜端面７４が、風向調整部材５０Ａの第１姿勢のときに互いに対向することから、風向調整部材５０Ａの後側への回動範囲を大きくすることができる。風向調整部材５０及びケーシング１１のこれら傾斜端面によって回動範囲が大きくなる分だけ空調室内機１０の気流制御の制限を緩和することができる。 (7-4)
As shown in FIGS. 15 and 16, the inclined end surface 57A as the hollow portion of the airflow direction adjusting member 50A and the inclined end surface 74 of the casing 11 are opposed to each other when the airflow direction adjusting member 50A is in the first posture. The range of rotation of the airflow direction adjusting member 50A toward the rear side can be increased. The restriction on the air flow control of the air conditioning indoor unit 10 can be relaxed by the amount of the rotation range increased by the inclined end surfaces of the wind direction adjusting member 50 and the casing 11.

　風向調整部材５０に窪み部５７を設けない場合に比べて、風向調整部材５０の後端部の窪み部５７によって風向調整部材５０の後端部の強度が低下している。窪み部５７の側部にフランジ５９を設けることにより、フランジ５９によって風向調整部材５０が補強され、風向調整部材５０の後端部に窪み部５７を設けても風向調整部材５０の変形を抑制することができる。フランジ５９によって風向調整部材５０が補強されることにより、風向調整部材５０の変形による風向調整機能の低下を防止することができるとともに風向調整部材５０の変形によって意匠性が悪くなるのを防止することができる。 (7-5)
The strength of the rear end portion of the wind direction adjusting member 50 is reduced by the recess portion 57 at the rear end portion of the wind direction adjusting member 50 as compared with the case where the hollow portion 57 is not provided in the wind direction adjusting member 50. By providing the flange 59 on the side of the recess 57, the wind direction adjusting member 50 is reinforced by the flange 59, and even if the recess 57 is provided at the rear end of the wind direction adjusting member 50, the deformation of the wind direction adjusting member 50 is suppressed. be able to. By reinforcing the wind direction adjusting member 50 by the flange 59, it is possible to prevent the wind direction adjusting function from being deteriorated due to the deformation of the wind direction adjusting member 50 and to prevent the design of the wind direction adjusting member 50 from being deteriorated by the deformation of the wind direction adjusting member 50. Can do.
