FIG. 4 is a cross-sectional view of the air conditioning indoor unit when operation is stopped. 3 and 4, the front flap 31 is accommodated in the accommodating portion 130 while the air conditioning operation is stopped.
図3は、図2における前フラップ31及び後フラップ40の拡大断面図である。また、図4は、運転停止時の空調室内機の断面図である。図3及び図4において、前フラップ31は、空調運転が停止している間は収容部130に収容されている。 (2-5)
3 is an enlarged cross-sectional view of the
前フラップ31は回動することによって収容部130から離れる。前フラップ31の回動軸は、吹出口形成壁16の上隔壁161の前リブ15aの下方に設定されており、前フラップ31の後端と回動軸とは所定の間隔を保って連結されている。それゆえ、前フラップ31が回動して収容部130から離れるほど、前フラップ31の後端の高さ位置は低くなるように回転する。
The front flap 31 moves away from the accommodating portion 130 by rotating. The rotation axis of the front flap 31 is set below the front rib 15a of the upper partition wall 161 of the blower outlet forming wall 16, and the rear end of the front flap 31 and the rotation shaft are connected at a predetermined interval. ing. Therefore, the height position of the rear end of the front flap 31 is rotated so that the front flap 31 is rotated away from the accommodating portion 130.
前フラップ31は、図4正面視反時計方向に回動することによって、前フラップ31の前端および後端ともに円弧を描きながら収容部130から離れる。また、前フラップ31は、図2正面視時計方向に回動することによって、前フラップ31は収容部130に近づき、最終的に収容部130に収容される。
The front flap 31 is moved counterclockwise when viewed from the front in FIG. 4, so that the front and rear ends of the front flap 31 are separated from the housing portion 130 while drawing an arc. Further, the front flap 31 is rotated clockwise in FIG. 2 when viewed from the front of FIG. 2, so that the front flap 31 approaches the housing portion 130 and is finally housed in the housing portion 130.
前フラップ31の運転状態の姿勢としては、収容部130に収容された姿勢(図4参照)、回転して前方上向きに傾斜した姿勢、さらに回転してほぼ水平な姿勢、さらに回転して前方下向きに傾斜した姿勢、さらに回転して後方下向きに傾斜した姿勢(図2,3参照)がある。
The operating state of the front flap 31 includes the attitude accommodated in the accommodating portion 130 (see FIG. 4), the attitude rotated and tilted forward and upward, further rotated and substantially horizontal, and further rotated and downwardly forward. There are postures that are inclined to the rear, and postures that are further rotated and inclined backward and downward (see FIGS. 2 and 3).
前フラップ31は、収容部130に収容された姿勢のときに外側の面を成す第1面31aと、内側の面を成す第2面31bとを有している。第1面31a及び第2面31bは、前フラップ31が図3の後方下向きに傾斜した姿勢をとったときには、それぞれ後面及び前面を成す。
The front flap 31 has a first surface 31a that forms an outer surface and a second surface 31b that forms an inner surface when the front flap 31 is in the posture of being accommodated in the accommodating portion 130. The first surface 31a and the second surface 31b form a rear surface and a front surface, respectively, when the front flap 31 is inclined downward and rearward in FIG.
第1面31aには、図3に示すように前フラップ31の厚み方向に寸法が小さくなる窪み部311が設けられている。窪み部311は、前フラップ31の中央から視て回動軸寄りに位置している。
As shown in FIG. 3, the first surface 31 a is provided with a recess 311 whose size decreases in the thickness direction of the front flap 31. The recess 311 is located closer to the rotation axis when viewed from the center of the front flap 31.
また、前フラップ31の長手方向(図2の紙面に垂直な方向)の寸法は、後フラップ40の長手方向の寸法と同じ又はそれ以上となるように設定されている。その理由は、例えば風向が上向きの場合に、後フラップ40で風向調節された吹出空気すべてを前フラップ31で受けるためであり、その作用・効果は前フラップ31の側方からの吹出空気がショートサーキットすることを防止することである。
Further, the dimension of the front flap 31 in the longitudinal direction (direction perpendicular to the paper surface of FIG. 2) is set to be equal to or larger than the dimension of the rear flap 40 in the longitudinal direction. The reason is that, for example, when the wind direction is upward, all of the blown air whose wind direction is adjusted by the rear flap 40 is received by the front flap 31, and the action / effect is short of the blown air from the side of the front flap 31. It is to prevent the circuit.
(2-6)サブ前フラップ32
サブ前フラップ32は、前フラップ31よりも吹出空気の流れの上流側に位置する板状の部材である。サブ前フラップ32は前フラップ31よりも小さいが、サブ前フラップ32は吹出流路18を通った空気を前フラップ31の第1面31aへ導くに十分な大きさに設定されている。 (2-6)Sub-front flap 32
Thesub-front flap 32 is a plate-like member that is located upstream of the front flap 31 in the flow of blown air. The sub-front flap 32 is smaller than the front flap 31, but the sub-front flap 32 is set to a size sufficient to guide the air that has passed through the blowout flow path 18 to the first surface 31 a of the front flap 31.
サブ前フラップ32は、前フラップ31よりも吹出空気の流れの上流側に位置する板状の部材である。サブ前フラップ32は前フラップ31よりも小さいが、サブ前フラップ32は吹出流路18を通った空気を前フラップ31の第1面31aへ導くに十分な大きさに設定されている。 (2-6)
The
サブ前フラップ32は、使用されないときには吹出口形成壁16の上隔壁161に設けられた収容部16aに収容されている。サブ前フラップ32は、収容部16aに収容された姿勢のときに下側の面を成す第1面32aと、上側の面を成す第2面32bとを有している。第1面32a及び第2面32bは、サブ前フラップ32が図3の姿勢をとったときには、それぞれ後面及び前面を成す。
The sub-front flap 32 is accommodated in an accommodating portion 16a provided in the upper partition wall 161 of the blower outlet forming wall 16 when not used. The sub-front flap 32 has a first surface 32a that forms a lower surface and a second surface 32b that forms an upper surface when in the posture of being accommodated in the accommodating portion 16a. The first surface 32a and the second surface 32b form a rear surface and a front surface, respectively, when the sub-front flap 32 takes the posture shown in FIG.
収容部16aは、吹出口形成壁16の上隔壁161を厚み方向に窪ませることによって形成される。収容部16aの深さは、サブ前フラップ32を収容した際にサブ前フラップ32の第1面32aが上隔壁161の面よりも流路側へ突出しないように設定されている。
The accommodating part 16a is formed by denting the upper partition 161 of the blower outlet forming wall 16 in the thickness direction. The depth of the accommodating portion 16a is set so that the first surface 32a of the sub-front flap 32 does not protrude toward the flow path side from the surface of the upper partition wall 161 when the sub-front flap 32 is accommodated.
また、サブ前フラップ32は、使用されるとき、回動によって収容部16aから移動して上隔壁161の面よりも流路側へ突出する。サブ前フラップ32の回動軸は、収容部16aの上流側端部の下方に設定されている。
Further, when the sub-front flap 32 is used, it moves from the accommodating portion 16a by rotation and protrudes to the flow path side from the surface of the upper partition wall 161. The rotation axis of the sub-front flap 32 is set below the upstream end of the accommodating portion 16a.
例えば、図3に示すように前フラップ31が後方下向きに傾斜した姿勢をとったときには、サブ前フラップ32は自己の先端が前フラップ31の窪み部311に入り込むように回動する。このとき、サブ前フラップ32全体が収容部16aから離れると上隔壁161とサブ前フラップ32との隙間から吹出空気がバイパスするので、それを防止するためにサブ前フラップ32の後端が収容部16aに残り、上隔壁161とサブ前フラップ32との隙間の拡大を抑制している。
For example, when the front flap 31 is inclined backward and downward as shown in FIG. 3, the sub front flap 32 rotates so that its front end enters the recess 311 of the front flap 31. At this time, since the blown air bypasses the gap between the upper partition wall 161 and the sub front flap 32 when the entire sub front flap 32 is separated from the housing portion 16a, the rear end of the sub front flap 32 is placed in the housing portion in order to prevent this. 16a remains and the expansion of the gap between the upper partition wall 161 and the sub-front flap 32 is suppressed.
この後、サブ前フラップ32の第1面32aと前フラップ31の第1面31aとが気流ガイド面30aを成し、後フラップ40と共に側壁の下部に向かう気流を生成する。
Thereafter, the first surface 32a of the sub-front flap 32 and the first surface 31a of the front flap 31 form an air flow guide surface 30a, and an air flow toward the lower portion of the side wall is generated together with the rear flap 40.
(2-7)後フラップ40
後フラップ40は、図4に示すように吹出口15を塞ぐことができる程度の面積を有している。後フラップ40は、吹出口15を閉じた姿勢のときに外側の面を成す第1面40aと、内側の面を成す第2面40bとを有している。第1面32a及び第2面32bは、後フラップ40が図3の後方下向きに傾斜した姿勢をとったときには、それぞれ後面及び前面を成す。 (2-7)Rear flap 40
Therear flap 40 has an area that can close the air outlet 15 as shown in FIG. The rear flap 40 has a first surface 40a that forms an outer surface and a second surface 40b that forms an inner surface when the air outlet 15 is closed. The first surface 32a and the second surface 32b form a rear surface and a front surface, respectively, when the rear flap 40 takes a posture in which the rear flap 40 is inclined rearward and downward in FIG.
後フラップ40は、図4に示すように吹出口15を塞ぐことができる程度の面積を有している。後フラップ40は、吹出口15を閉じた姿勢のときに外側の面を成す第1面40aと、内側の面を成す第2面40bとを有している。第1面32a及び第2面32bは、後フラップ40が図3の後方下向きに傾斜した姿勢をとったときには、それぞれ後面及び前面を成す。 (2-7)
The
第1面40aは、意匠性を重視して外側に凸のなだらかな円弧曲面に仕上げられている。これに対し、第2面40bは、平面40baと湾曲面40bbとを含んでおり、図3に示すように、後フラップ40の上端から下端に向かって平面40ba及び湾曲面40bbの順に配置されている。また、図3において湾曲面40bbは、半径200mm以上の前側に膨らむ湾曲面である。
The first surface 40a is finished with a gentle circular curved surface that is convex outward with emphasis on design. In contrast, the second surface 40b includes a flat surface 40ba and a curved surface 40bb, and is arranged in the order of the flat surface 40ba and the curved surface 40bb from the upper end to the lower end of the rear flap 40 as shown in FIG. Yes. In FIG. 3, the curved surface 40bb is a curved surface that swells to the front side with a radius of 200 mm or more.
後フラップ40の回動軸は、吹出口形成壁16の下隔壁162の後リブ15bに隣接する位置に設定されている。後フラップ40が、回動軸回りに図4正面視反時計方向に回動することによって、後フラップ40が吹出口15の前端から遠ざかるように動作して吹出口15を開ける。逆に、後フラップ40が、回動軸回りに図2正面視時計方向に回動することによって、後フラップ40が吹出口15の前端へ近づくように動作して吹出口15を閉じる。
The rotation axis of the rear flap 40 is set at a position adjacent to the rear rib 15b of the lower partition 162 of the blower outlet forming wall 16. When the rear flap 40 rotates about the rotation axis in the counterclockwise direction of FIG. 4 when viewed from the front, the rear flap 40 operates to move away from the front end of the air outlet 15 to open the air outlet 15. On the contrary, the rear flap 40 rotates in the clockwise direction in FIG. 2 around the rotation axis, so that the rear flap 40 moves closer to the front end of the outlet 15 and closes the outlet 15.
後フラップ40が吹出口15を開けている状態において、吹出口15から吹き出された吹出空気は、後フラップ40の第2面40bに概ね沿って流れる。
In a state where the rear flap 40 opens the air outlet 15, the air blown out from the air outlet 15 flows along the second surface 40 b of the rear flap 40 substantially.

(3-1)後方下向き気流モード
後方下向き気流モードは、吹出空気を空調室内機10が設置されている側壁の下部に向けるモードである。後方下向き気流モードでは、吹出空気は、側壁の下部から床面に至り、床面に沿いながら対向する側壁に向かって流れる。この気流は、居住者に直に当たらず空気の流れを感じさせ難いことから「無感気流」ともいう。 (3-1) Rear Downward Airflow Mode The rearward downward airflow mode is a mode in which the blown air is directed to the lower part of the side wall where the air conditioningindoor unit 10 is installed. In the rear downward airflow mode, the blown air flows from the lower part of the side wall to the floor surface and flows toward the opposite side wall along the floor surface. This airflow is also called “insensitive airflow” because it does not directly hit the resident and it is difficult to feel the air flow.

後方下向き気流モードでは、前フラップ31、サブ前フラップ32及び後フラップ40は図1~図3に示した姿勢をとる。図3で言えば、サブ前フラップ32は自己の下端を上端より前側に位置させて垂直面に対して角度α(0~10°)だけ傾斜させる。
In the rear downward airflow mode, the front flap 31, the sub front flap 32, and the rear flap 40 take the posture shown in FIGS. In FIG. 3, the sub-front flap 32 is inclined at an angle α (0 to 10 °) with respect to the vertical plane with its lower end positioned in front of the upper end.
また、前フラップ31は自己の下端を上端よりも側壁側に位置させて垂直面に対して角度β(0~20°)だけ傾斜する。これによって、サブ前フラップ32の第1面32aと前フラップ31の第1面31aとが前側に膨出する凸形状の気流ガイド面30aを形成する。
Also, the front flap 31 is inclined at an angle β (0 to 20 °) with respect to the vertical plane with its lower end positioned on the side wall side from the upper end. Thereby, the convex airflow guide surface 30a in which the first surface 32a of the sub front flap 32 and the first surface 31a of the front flap 31 bulge forward is formed.
このときの前フラップ31の下端は、[吹出口15の後端位置から鉛直下方に突出する後リブ15b]の先端の高さ位置よりも下方に位置する。後リブ15bの先端は、吹出口15の最下端である。
At this time, the lower end of the front flap 31 is located below the height position of the tip of [the rear rib 15b protruding vertically downward from the rear end position of the blowout port 15]. The front end of the rear rib 15 b is the lowermost end of the air outlet 15.
一方、後フラップ40は自己の下端を上端よりも側壁側に位置させて第2面40bを垂直面に対して傾斜させる。具体的には図3に示すように、後リブ15bの先端に後フラップ40の第1面40aが接触、若しくは近接するまで後フラップ40が傾斜する。
On the other hand, the rear flap 40 has its lower end positioned on the side of the side wall with respect to the upper end, and the second surface 40b is inclined with respect to the vertical plane. Specifically, as shown in FIG. 3, the rear flap 40 is inclined until the first surface 40 a of the rear flap 40 contacts or approaches the tip of the rear rib 15 b.
本実施形態では、後フラップ40と後リブ15bとの隙間が一定値(5mm)以下になっているので、その隙間を空気が流れるときの通風抵抗が増大しており、吹出空気はその隙間を避けてもっと広い通路である気流ガイド面30aと第2面40bとで挟まれた風路空間に流れる。
In the present embodiment, since the gap between the rear flap 40 and the rear rib 15b is equal to or less than a predetermined value (5 mm), the ventilation resistance when air flows through the gap is increased, and the blown air passes through the gap. The airflow guide space 30a and the second surface 40b, which is a wider passage, are avoided and flow into the air passage space.
したがって、吹出空気は、気流ガイド面30aと第2面40bとで挟まれた風路空間を通過する。その際、サブ前フラップ32に案内された吹出空気がそれよりも大きい前フラップ31に沿う。前フラップ31は自己の下端を上端よりも側壁側に位置させ垂直面に対して傾斜しているので、吹出空気を水平よりも90°以上下向きの側壁下部へ導くことができる。
Therefore, the blown air passes through the air passage space sandwiched between the airflow guide surface 30a and the second surface 40b. In that case, the blowing air guided to the sub front flap 32 follows the front flap 31 larger than that. Since the front flap 31 is inclined with respect to the vertical plane with the lower end of the front flap 31 positioned on the side of the side of the upper end, the blown air can be guided to the lower side of the side wall downward by 90 ° or more from the horizontal.
また、気流ガイド面30aと第2面40bとで挟まれた風路空間を通過する吹出空気は、後リブ15bの先端(吹出口15の最下端)の高さ位置より下方に到達するまで、前方への拡散を前フラップ31に阻止された状態で当該風路空間に沿って進む。吹出空気は、当該風路空間を離れる際には後フラップ40の第2面40bに沿った気流となっているので、側壁の下部に向かう気流が十分に生成される。
Further, until the blown air passing through the air passage space sandwiched between the airflow guide surface 30a and the second surface 40b reaches below the height position of the tip of the rear rib 15b (the lowermost end of the blowout port 15), The vehicle advances along the air passage space in a state where forward diffusion is prevented by the front flap 31. Since the blown air becomes an air flow along the second surface 40b of the rear flap 40 when leaving the air passage space, the air flow toward the lower portion of the side wall is sufficiently generated.
さらに、吹出空気は後フラップ40の第2面40bの平面40ba及び湾曲面40bbの順に沿って流れる。湾曲面40bbは、コアンダ効果を発揮し易いように半径200mm以上に設定されているので、吹出空気は平面40baに沿った下向き気流になった後にコアンダ効果によって湾曲面40bbに引き寄せられて側壁の下部に向かう気流となる。
Furthermore, the blown air flows along the order of the flat surface 40ba and the curved surface 40bb of the second surface 40b of the rear flap 40. Since the curved surface 40bb is set to have a radius of 200 mm or more so that the Coanda effect can be easily exerted, the blown air is drawn downward to the curved surface 40bb by the Coanda effect after becoming a downward air flow along the plane 40ba, and the lower portion of the side wall. The airflow toward
以上にように、前フラップ31及びサブ前フラップ32による前フラップ群30と後フラップ40とが相互に作用することによって、側壁の下部に向かう後方下向き気流(無感気流)が容易に生成される。
As described above, when the front flap group 30 and the rear flap 40 by the front flap 31 and the sub front flap 32 interact with each other, a backward downward airflow (insensitive airflow) toward the lower portion of the side wall is easily generated. .

(3-2-1)サブ前フラップ32を利用するモード
図5は、サブ前フラップ32を利用する前方下向き気流モード時の空調室内機10の断面図である。また図6は、図5における前フラップ31、サブ前フラップ32及び後フラップ40の拡大断面図である。 (3-2-1) Mode UsingSub-Front Flap 32 FIG. 5 is a cross-sectional view of the air conditioning indoor unit 10 in the forward downward airflow mode using the sub-front flap 32. 6 is an enlarged cross-sectional view of the front flap 31, the sub-front flap 32, and the rear flap 40 in FIG.
図5は、サブ前フラップ32を利用する前方下向き気流モード時の空調室内機10の断面図である。また図6は、図5における前フラップ31、サブ前フラップ32及び後フラップ40の拡大断面図である。 (3-2-1) Mode Using
図5及び図6において、先ず、前フラップ31が回動して、前フラップ31の第1面31aが水平よりも所定角度x1だけ下向きに傾斜する姿勢をとる。なお、第1面31aが円弧面のため角度の基準がとり難い場合には、図6に示すよう、第1面31aの両端を結ぶ線を角度の基準としてもよい。
5 and 6, first, the front flap 31 is rotated so that the first surface 31a of the front flap 31 is inclined downward by a predetermined angle x1 from the horizontal. If the first surface 31a is an arc surface and it is difficult to determine the angle, a line connecting both ends of the first surface 31a may be used as the angle reference, as shown in FIG.
また、サブ前フラップ32も回動して、サブ前フラップ32の第1面32aが水平よりも所定角度y1だけ下向きに傾斜する姿勢をとる。このとき、サブ前フラップ32全体が収容部16aから離れると上隔壁161とサブ前フラップ32との隙間から吹出空気がバイパスするので、それを防止するためにサブ前フラップ32の後端が収容部16aに残り、上隔壁161とサブ前フラップ32との隙間の拡大を抑制している。
Further, the sub-front flap 32 is also rotated so that the first surface 32a of the sub-front flap 32 is inclined downward by a predetermined angle y1 from the horizontal. At this time, since the blown air bypasses the gap between the upper partition wall 161 and the sub front flap 32 when the entire sub front flap 32 is separated from the housing portion 16a, the rear end of the sub front flap 32 is placed in the housing portion in order to prevent this. 16a remains and the expansion of the gap between the upper partition wall 161 and the sub-front flap 32 is suppressed.
さらに、後フラップ40も回動して、後フラップ40の第2面40bの平面40baが水平よりも所定角度z1だけ下向きに傾斜する姿勢をとる。
Further, the rear flap 40 also rotates, and the flat surface 40ba of the second surface 40b of the rear flap 40 is inclined downward by a predetermined angle z1 from the horizontal.
図6に示すように、前フラップ31及びサブ前フラップ32を水平方向前方から視たとき、サブ前フラップ32の前端部は、前フラップ31よりも吹出空気の流れの上流側で且つ前フラップ31の後端面より鉛直下方で、前フラップ31の後端部と寸法Lだけ重なっている。
As shown in FIG. 6, when the front flap 31 and the sub front flap 32 are viewed from the front in the horizontal direction, the front end portion of the sub front flap 32 is upstream of the front flap 31 and the front flap 31. It overlaps the rear end of the front flap 31 by a dimension L vertically below the rear end surface.
前フラップ31、サブ前フラップ32及び両者の隙間の位置関係は、吹出空気の流れの上流側から視て、サブ前フラップ32、当該隙間、前フラップ31の順で並ぶ関係となり、当該隙間がその上流側のサブ前フラップ32によって隠れるので、吹出流路18を通過してサブ前フラップ32の第1面32aに案内された空気は、勢い、当該隙間に回らずに前フラップ31の第1面31aに流れる。その結果、当該隙間があったとしても空調空気がその隙間へバイパスすることは防止される。
The positional relationship between the front flap 31, the sub front flap 32, and the gap between them is a relationship in which the sub front flap 32, the gap, and the front flap 31 are arranged in this order, as viewed from the upstream side of the flow of the blown air. Since it is hidden by the upstream sub-front flap 32, the air guided to the first surface 32 a of the sub-front flap 32 through the blow-out flow path 18 is vigorous and does not rotate around the gap, but the first surface of the front flap 31. It flows to 31a. As a result, even if there is the gap, the conditioned air is prevented from bypassing the gap.
上記のように、サブ前フラップ32を利用する前方下向き気流モードでは、サブ前フラップ32が上隔壁161と前フラップ31との隙間を通る気流を阻む姿勢を採り、前フラップ31の上端を境に吹出空気が前フラップ31の両面に沿って流れることを防止するので、前フラップ31の上端が通風抵抗にならない。その結果、室内ファン14の消費電力上昇、省エネ性能の低下が防止される。
As described above, in the forward downward airflow mode using the sub-front flap 32, the sub-front flap 32 takes a posture of blocking the airflow passing through the gap between the upper partition wall 161 and the front flap 31, and the upper end of the front flap 31 is the boundary. Since blowing air is prevented from flowing along both surfaces of the front flap 31, the upper end of the front flap 31 does not become ventilation resistance. As a result, an increase in power consumption of the indoor fan 14 and a decrease in energy saving performance are prevented.
また、サブ前フラップ32を利用する前方下向き気流モードは、特に冷房運転における前方下向きの吹出空気を発生させる際に有用である。なぜなら、冷却された空気が前フラップ31の第2面31b側へ流れないので、結露防止という効果を奏するからである。
Further, the forward downward air flow mode using the sub-front flap 32 is particularly useful when generating forward downward air blowing in the cooling operation. This is because the cooled air does not flow to the second surface 31b side of the front flap 31 and thus has an effect of preventing condensation.
本実施形態では、冷房運転において、上向きの気流を発生させる場合を除き、サブ前フラップ32を使用している。
In the present embodiment, the sub-front flap 32 is used in the cooling operation except when an upward airflow is generated.
(3-2-2)サブ前フラップ32を利用しないモード
図7は、サブ前フラップ32を利用しない前方下向き気流モード時の空調室内機10の断面図である。図7において、サブ前フラップ32は収容部16aに収容されており、サブ前フラップ32の第1面32aは、隣接する上隔壁161の延長面上に沿っており、上隔壁161に沿った空気の流れを妨げない。 (3-2-2) Mode Not UsingSub-Front Flap 32 FIG. 7 is a cross-sectional view of the air conditioning indoor unit 10 in the forward downward airflow mode that does not use the sub-front flap 32. In FIG. 7, the sub-front flap 32 is accommodated in the accommodating portion 16 a, and the first surface 32 a of the sub-front flap 32 is along the extended surface of the adjacent upper partition 161, and the air along the upper partition 161 Does not obstruct the flow.
図7は、サブ前フラップ32を利用しない前方下向き気流モード時の空調室内機10の断面図である。図7において、サブ前フラップ32は収容部16aに収容されており、サブ前フラップ32の第1面32aは、隣接する上隔壁161の延長面上に沿っており、上隔壁161に沿った空気の流れを妨げない。 (3-2-2) Mode Not Using
サブ前フラップ32を利用しない前方下向き気流モードでは、サブ前フラップ32自身は通風抵抗にならない。しかし、サブ前フラップ32が上隔壁161と前フラップ31との隙間を通る気流を阻止できないので、前フラップ31の上端が通風抵抗になることは否めない。
In the forward downward airflow mode that does not use the sub-front flap 32, the sub-front flap 32 itself does not become a draft resistance. However, since the sub-front flap 32 cannot prevent the airflow passing through the gap between the upper partition wall 161 and the front flap 31, it cannot be denied that the upper end of the front flap 31 becomes a ventilation resistance.

図8は、サーキュレーション気流モード時の空調室内機10の部分断面図である。図8において、前フラップ31は水平姿勢、或いは前端を水平前方に向ける姿勢をとっている。サブ前フラップ32は、収容部16aに収容されている。後フラップ40は、第2面40bの平面40baが吹出口形成壁16の下隔壁162の終端の接線の延長上に沿う傾斜姿勢をとっている。下隔壁162も下スクロール172の終端の接線の延長上に沿うように傾斜しているので、あたかも下スクロール172、下隔壁162及び平面40baが1つのスクロール壁を形成しているように並び、空気の流れは妨げられることなく後フラップ40の第2面40b上に導かれる。 (3-3-1) Circulation Airflow Mode FIG. 8 is a partial cross-sectional view of the air conditioningindoor unit 10 in the circulation airflow mode. In FIG. 8, the front flap 31 takes a horizontal posture or a posture in which the front end is directed horizontally forward. The sub-front flap 32 is accommodated in the accommodating portion 16a. The rear flap 40 has an inclined posture in which the flat surface 40ba of the second surface 40b is along the extension of the tangent at the end of the lower partition 162 of the blower outlet forming wall 16. Since the lower partition 162 is also inclined along the extension of the tangent at the terminal end of the lower scroll 172, the lower scroll 172, the lower partition 162, and the plane 40ba are arranged so as to form one scroll wall. Is guided to the second surface 40b of the rear flap 40 without being interrupted.

サーキュレーション気流モードでは、前フラップ31の第1面31aと後フラップ40の第2面40bとの間隔が狭いので、吹出空気は絞られて流速が増し、勢い良く前方に送りだされ、空調対象空間の空気を攪拌する。その結果、空調対象空間の空気のよどみを解消することができる。
In the circulation airflow mode, since the distance between the first surface 31a of the front flap 31 and the second surface 40b of the rear flap 40 is narrow, the blown air is squeezed to increase the flow velocity, and the air is sent forward. Stir the air in the space. As a result, air stagnation in the air-conditioning target space can be eliminated.
(3-3-2)中間気流モード
図9は、中間気流モード時の空調室内機10の部分断面図である。図9において、前フラップ31は前端を水平よりも上に向ける姿勢をとっている。サブ前フラップ32は、収容部16aに収容されている。後フラップ40は、第2面40bの平面40baが前方下向きに傾斜する姿勢をとっている。 (3-3-2) Intermediate Airflow Mode FIG. 9 is a partial cross-sectional view of the air conditioningindoor unit 10 in the intermediate airflow mode. In FIG. 9, the front flap 31 takes a posture in which the front end is directed above the horizontal. The sub-front flap 32 is accommodated in the accommodating portion 16a. The rear flap 40 has a posture in which the flat surface 40ba of the second surface 40b is inclined forward and downward.

一見、吹出空気は後フラップ40の平面40baに沿って前方下向きに流れるようにも思えるが、吹出口15を出た吹出空気はコアンダ効果によって前フラップ31の第1面31aに引き寄せられて水平及び水平よりもやや上向きの気流となって送り出される。
At first glance, it seems that the blown air flows forward and downward along the plane 40ba of the rear flap 40. However, the blown air that has exited the blowout port 15 is attracted to the first surface 31a of the front flap 31 by the Coanda effect and becomes horizontal and It is sent out as a slightly upward airflow from the horizontal.
ここで、コアンダ効果とは、気体や液体の流れのそばに壁があると、流れの方向と壁の方向とが異なっていても、壁面に沿った方向に流れようとする現象である(朝倉書店「法則の辞典」)。
Here, the Coanda effect is a phenomenon in which if there is a wall near the flow of gas or liquid, it will flow in the direction along the wall even if the direction of the flow is different from the direction of the wall (Asakura). Bookstore "Dictionary of the Law").
図9において、前フラップ31の第1面31aにコアンダ効果を生じさせるには、前フラップ31と後フラップ40とが所定の開き角度以下になる必要がある。両者の位置関係については、出願人によって平成23年9月30日に出願された特許文献(特開2013-76530)に開示されているので、ここでは説明を省略する。
In FIG. 9, in order to produce the Coanda effect on the first surface 31a of the front flap 31, the front flap 31 and the rear flap 40 need to be less than a predetermined opening angle. Since the positional relationship between the two is disclosed in a patent document (Japanese Patent Laid-Open No. 2013-76530) filed on September 30, 2011 by the applicant, description thereof is omitted here.

空調室内機10では、前フラップ群30(前フラップ31及びサブ前フラップ32)と後フラップ40とで挟まれた風路空間を通過する吹出空気は、吹出口15の最下端より下方に到達するまで、前方への拡散を前フラップ31に阻止された状態で当該風路空間に沿って進み、当該風路空間を離れる際には後フラップ40の第2面40bに沿った気流となっているので、側壁の下部に向かう[無感気流]が十分に生成される。 (4) Features (4-1)
In the air conditioningindoor unit 10, the blown air passing through the air passage space sandwiched between the front flap group 30 (the front flap 31 and the sub front flap 32) and the rear flap 40 reaches below the lowermost end of the blowout port 15. Until the front flap 31 prevents the forward diffusion, the air travels along the air passage space. When leaving the air passage space, the air flows along the second surface 40b of the rear flap 40. Therefore, [insensitive airflow] toward the lower part of the side wall is sufficiently generated.

空調室内機10では、後方下向き気流(無感気流)を生成するときには、後フラップ40の下端が既に側壁側に向いている上に、第2面40bの湾曲面40bbが前側に膨らんでいるので、湾曲面40bb終端の接線は後フラップ40の傾斜方向よりもさらに側壁側に向くことになる。したがって、後フラップ40の第2面40bを離れた後の吹出空気は、確実に後方下向き気流となる。 (4-2)
In the air conditioningindoor unit 10, when generating a rearward downward airflow (insensitive airflow), the lower end of the rear flap 40 is already facing the side wall side, and the curved surface 40bb of the second surface 40b is swollen forward. The tangent line at the end of the curved surface 40bb is further directed to the side wall side than the inclination direction of the rear flap 40. Therefore, the blown air after leaving the second surface 40b of the rear flap 40 is surely a rearward downward airflow.
空調室内機10では、後方下向き気流(無感気流)を生成するときには、後フラップ40の下端が既に側壁側に向いている上に、第2面40bの湾曲面40bbが前側に膨らんでいるので、湾曲面40bb終端の接線は後フラップ40の傾斜方向よりもさらに側壁側に向くことになる。したがって、後フラップ40の第2面40bを離れた後の吹出空気は、確実に後方下向き気流となる。 (4-2)

空調室内機10では、吹出空気は後フラップ40の第2面40bの平面40ba、湾曲面40bbの順に沿って流れるので、後方下向き気流を生成するときには、吹出空気は平面40baに沿った下向き気流になった後にコアンダ効果によって湾曲面40bbに引き寄せられて側壁の下部に向かう気流となる。したがって、後方下向き気流が容易に生成される。 (4-3)
In the air conditioningindoor unit 10, since the blown air flows along the plane 40ba of the second surface 40b of the rear flap 40 and the curved surface 40bb in this order, the blown air becomes a downward airflow along the plane 40ba when generating a downward airflow. After that, it is drawn to the curved surface 40bb by the Coanda effect and becomes an air flow toward the lower portion of the side wall. Therefore, a backward downward airflow is easily generated.

図10は、第1変形例に係る空調室内機10の前フラップ31、サブ前フラップ32及び後フラップ40の拡大断面図である。図10において、サブ前フラップ32の第2面32b側から厚み方向にその寸法が小さくなる窪み部321が形成されている。
FIG. 10 is an enlarged cross-sectional view of the front flap 31, the sub front flap 32, and the rear flap 40 of the air conditioning indoor unit 10 according to the first modification. In FIG. 10, a recess 321 whose size decreases in the thickness direction from the second surface 32 b side of the sub-front flap 32 is formed.
第1変形例では、風向モードが後方下向き気流モードのときに、前フラップ31とサブ前フラップ32とが重なる姿勢となるが、その際、前フラップ31の第1面31aの上端コーナー部がサブ前フラップ32の窪み部321に嵌り込むので、前フラップ31の第1面31aとサブ前フラップ32の第1面32aとの間に生じる段差が小さくなり、気流の乱れを抑制する。
In the first modified example, when the wind direction mode is the backward downward airflow mode, the front flap 31 and the sub front flap 32 are superposed. At this time, the upper end corner portion of the first surface 31a of the front flap 31 is the sub top portion. Since it fits in the hollow part 321 of the front flap 32, the level | step difference produced between the 1st surface 31a of the front flap 31 and the 1st surface 32a of the sub front flap 32 becomes small, and disturbance of airflow is suppressed.
(5-2)第2変形例
また、図3に示す実施形態、及び図10に示す第1変形例では、サブ前フラップ32の下端部分が前フラップ31の第1面31a側から重なっている。しかし、これに限定されるものではなく、サブ前フラップ32の下端部分が前フラップ31の第2面31b側から重なってもよい。 (5-2) Second Modification Also, in the embodiment shown in FIG. 3 and the first modification shown in FIG. 10, the lower end portion of thesub-front flap 32 overlaps from the first surface 31 a side of the front flap 31. . However, the present invention is not limited to this, and the lower end portion of the sub-front flap 32 may overlap from the second surface 31 b side of the front flap 31.
また、図3に示す実施形態、及び図10に示す第1変形例では、サブ前フラップ32の下端部分が前フラップ31の第1面31a側から重なっている。しかし、これに限定されるものではなく、サブ前フラップ32の下端部分が前フラップ31の第2面31b側から重なってもよい。 (5-2) Second Modification Also, in the embodiment shown in FIG. 3 and the first modification shown in FIG. 10, the lower end portion of the
図11は、第2変形例に係る空調室内機10の前フラップ31、サブ前フラップ32及び後フラップ40の拡大断面図である。図11において、サブ前フラップ32は、図3及び図10に記載のものと比較してその位置が前方へ移動している。それに伴い、収容部16aの位置及び形状も変更されている。
FIG. 11 is an enlarged cross-sectional view of the front flap 31, the sub-front flap 32, and the rear flap 40 of the air conditioning indoor unit 10 according to the second modification. In FIG. 11, the position of the sub-front flap 32 has moved forward as compared to that shown in FIGS. Along with this, the position and shape of the accommodating portion 16a are also changed.
サブ前フラップ32は、後端側に設定された回動軸を中心に図11正面視で反時計方向に回動することによって、サブ前フラップ32の下端部分が前フラップ31の第2面31b側から重なる。
The sub-front flap 32 rotates counterclockwise as viewed from the front in FIG. 11 around the rotation axis set on the rear end side, so that the lower end portion of the sub-front flap 32 is the second surface 31b of the front flap 31. Overlapping from the side.
サブ前フラップ32の重なり部を除く第1面32aと前フラップ31の第1面31aとは前方に凸の気流ガイド面30aを形成するので、吹出空気はサブ前フラップ32の第1面32aで前方下向きに偏向された直後に前フラップ31の第1面31aによって後方下向きに偏向される。
Since the first surface 32a excluding the overlapping portion of the sub front flap 32 and the first surface 31a of the front flap 31 form a forward airflow guide surface 30a, the blown air is generated by the first surface 32a of the sub front flap 32. Immediately after being deflected forward and downward, the first surface 31a of the front flap 31 deflects backward and downward.
その結果、吹出空気は、気流ガイド面30aと後フラップ40の第2面40bとで挟まれた風路空間を流れて後方下向き気流になる。
As a result, the blown air flows through the air passage space sandwiched between the airflow guide surface 30a and the second surface 40b of the rear flap 40 and becomes a rearward downward airflow.
(5-3)第3変形例
上記実施形態では、図6に示すように、サブ前フラップ32は吹出口形成壁16の上隔壁161に設けられた凹状の収容部16aに収容され、回動により流路に突出する構成とした。しかし、これに限定されるものではなく直線移動により流路に突出する構成であってもよい。 (5-3) Third Modification In the above embodiment, as shown in FIG. 6, thesub-front flap 32 is housed in the recessed housing portion 16 a provided in the upper partition wall 161 of the air outlet forming wall 16 and is rotated. Thus, the structure protruded into the flow path. However, the present invention is not limited to this, and may be configured to protrude into the flow path by linear movement.
上記実施形態では、図6に示すように、サブ前フラップ32は吹出口形成壁16の上隔壁161に設けられた凹状の収容部16aに収容され、回動により流路に突出する構成とした。しかし、これに限定されるものではなく直線移動により流路に突出する構成であってもよい。 (5-3) Third Modification In the above embodiment, as shown in FIG. 6, the
図12は、第3変形例に係る空調室内機10の前フラップ31、サブ前フラップ32及び後フラップ40の拡大断面図である。図12において、上隔壁161にはサブ前フラップ32を貫通させて奥に収容する空間である収容部16aが形成されている。
FIG. 12 is an enlarged cross-sectional view of the front flap 31, the sub front flap 32, and the rear flap 40 of the air conditioning indoor unit 10 according to the third modification. In FIG. 12, the upper partition wall 161 is formed with a housing portion 16 a that is a space that penetrates the sub-front flap 32 and is housed in the back.
サブ前フラップ32は、使用されないときは自己の前端が上隔壁161に隠れる程度まで収容部16a内に入り込む。そして、サブ前フラップ32が使用される前方下向き気流モードのときに直線移動により流路内に突出する。
When the sub-front flap 32 is not used, the sub-front flap 32 enters the accommodating portion 16a to the extent that its front end is hidden by the upper partition wall 161. When the sub front flap 32 is in the forward downward airflow mode, it projects into the flow path by linear movement.
(6)その他
図13は、後フラップ40と吹出口15との位置関係を示す当該後フラップ40近傍の断面図である。図13において、後フラップ40の上端は半径D2の円弧を成しており、その円弧中心と後フラップ40の回動中心とが略一致している。 (6) Others FIG. 13 is a cross-sectional view of the vicinity of therear flap 40 showing the positional relationship between the rear flap 40 and the outlet 15. In FIG. 13, the upper end of the rear flap 40 forms an arc having a radius D <b> 2, and the arc center and the rotation center of the rear flap 40 substantially coincide with each other.
図13は、後フラップ40と吹出口15との位置関係を示す当該後フラップ40近傍の断面図である。図13において、後フラップ40の上端は半径D2の円弧を成しており、その円弧中心と後フラップ40の回動中心とが略一致している。 (6) Others FIG. 13 is a cross-sectional view of the vicinity of the
後フラップ40は、回動によって自己の下端(水平姿勢のときは前端)を水平前方から後方下向きへ移動させる。回動時、後フラップ40の上端の円弧面は、吹出口15の後端位置から鉛直下方に突出する後リブ15bと一定の隙間D1を保っている。本実施形態では、この隙間D1は5mm以下に設定されている。
The rear flap 40 moves its lower end (front end when in a horizontal posture) from the horizontal front to the rear downward by rotating. At the time of rotation, the circular arc surface at the upper end of the rear flap 40 maintains a constant gap D1 with the rear rib 15b protruding vertically downward from the rear end position of the blowout port 15. In the present embodiment, the gap D1 is set to 5 mm or less.
後フラップ40の上端を通過する吹出空気は、隙間D1を流れようとしても通風抵抗が他の通風路に比べて大きすぎるので、隙間D1を通過せずに上端から第2面40b側へ流れる。
The blown air that passes through the upper end of the rear flap 40 flows to the second surface 40b side from the upper end without passing through the gap D1 because the ventilation resistance is too large compared to other ventilation paths even if it tries to flow through the gap D1.
上記の通り、隙間D1が一定値以下に設定されているので、吹出空気が隙間D1を通って第1面40a側に流れることはない。そのため、本実施形態では後フラップ40の第1面40aを、風向制御に関与させることなく、本体ケーシング11の意匠の一部として扱うことができる。
As described above, since the gap D1 is set to a certain value or less, the blown air does not flow to the first surface 40a side through the gap D1. Therefore, in the present embodiment, the first surface 40a of the rear flap 40 can be handled as part of the design of the main body casing 11 without being involved in wind direction control.
