Abstract
Description
例えば、特許文献1(特開昭62-10553号公報)に記載の空気調和機では、吹出口の左右の側壁が、より広い左右への調和空気の吹き出しを阻害している点に着目し、吹出方向に向かうにつれて、吹出口の左右の幅が拡大するように湾曲させた構造を採用している。吹出口の左右の側壁を拡大させた形状を採用したこの空気調和機では、調和空気を左右に幅広く吹き出す状態で、吹出口の左右の側壁への空気流れが衝突してしまうことを抑えて、調和空気を左右方向に広げることを可能にしている。また、この左右に幅を拡大させた側壁部分では、左右方向になだらかに湾曲して形成された面を採用しているため、コアンダ効果が得られ、調和空気の吹出流れを湾曲面に沿わせることができ、さらに左右方向に広げることが可能になっている。以上により、調和空気を左右方向により広く吹き出すことができている。 Conventionally, in wall-mounted air conditioning indoor units, positions where air outlets can be provided are limited compared to ceiling-suspended air conditioners, so conditioned air is blown more widely from the air outlet in the left-right direction. Is required.
For example, in the air conditioner described in Patent Document 1 (Japanese Patent Application Laid-Open No. Sho 62-10553), attention is paid to the fact that the left and right side walls of the air outlet obstruct the wider conditioned air blowing to the left and right. A structure that is curved so that the left and right widths of the air outlet expand as it goes in the air blowing direction is adopted. In this air conditioner adopting a shape in which the left and right side walls of the air outlet are enlarged, the air flow to the left and right side walls of the air outlet is prevented from colliding in a state where the conditioned air is blown widely left and right, It makes it possible to spread conditioned air in the left-right direction. In addition, since the side wall portion whose width is expanded to the left and right employs a surface that is gently curved in the left and right direction, a Coanda effect is obtained, and the flow of conditioned air is made to follow the curved surface. Can be further expanded in the left-right direction. As described above, the conditioned air can be blown more widely in the left-right direction.
しかしながら、吹出口の左右の側面を、このように室内側に長く伸ばした形状を採用した場合には、装置が大型化してしまうことになる。 In the air conditioner described in Patent Document 1, since a wide space is secured between the left and right side walls of the outlet and the vertical flap, the vertical flap and the vertical flap The flow of conditioned air passing between the left and right side walls remains at a high wind speed. Such a flow of conditioned air has a high wind speed and is difficult to bend suddenly in the left-right direction. For this reason, in the above air conditioner, in order to widen the flow of conditioned air with a high wind speed little by little by the Coanda effect, the air conditioner slightly increases in the left-right direction toward the indoor side (traveling direction when the air flow goes straight). The curved shape is formed so as to spread. This curved shape is a shape that extends long toward the indoor side in order to secure the length of the air flow along the surface (the length that provides the Coanda effect) as long as possible.
However, if the left and right side surfaces of the air outlet are elongated in the indoor side as described above, the apparatus becomes large.
ここで、「調和空気の空気流れの下流側ほど所定側壁に近い姿勢となっている状態」とは、ストッパ等の規制手段によって風向案内羽根が構造的に所定側壁に最も近づいている状態であってもよいし、風向案内羽根の傾斜状態が制御される場合において最も所定側壁に近づいている状態であってもよい。 The air conditioning indoor unit according to the first aspect is a wall-hanging air conditioning indoor unit, and includes a casing and a wind direction adjusting unit. The casing has a blowout flow path for conditioned air. The wind direction adjusting unit is disposed in the vicinity of the outlet of the blowing channel and has a plurality of wind direction guide vanes for adjusting the wind direction. The plurality of wind direction guide vanes are located between the left and right side walls of the blowing channel. The wind direction guide vane located closest to the predetermined side wall which is one of the left and right side walls is in a state closer to the predetermined side wall toward the downstream side of the air flow of conditioned air, The gap between the first portion, which is a part of the downstream end, and the predetermined side wall is 10 mm or less, and the second portion other than the first portion of the downstream end, The gap between them has a part larger than 10 mm.
Here, “the state where the downstream side of the air flow of the conditioned air is closer to the predetermined side wall” is a state where the airflow direction guide vane is structurally closest to the predetermined side wall by a regulating means such as a stopper. Alternatively, it may be a state that is closest to the predetermined side wall when the inclination state of the wind direction guide vane is controlled.
この空調室内機では、吹き出される調和空気は、所定側壁と風向案内羽根の第1部分との間の隙間が10mm以下となっている部分は通過しにくく、所定側壁との間の隙間が10mmより大きくなっている部分を主として通過する。このため、吹き出される調和空気は、所定側壁と風向案内羽根との間を通過する際に、「風向案内羽根の第1部分と所定側壁との間の隙間が10mm以下に狭く形成されている部分を通過することで流速が速められる」ということは生じにくい。吹き出される調和空気は、むしろ、風向案内羽根の第1部分と所定側壁との間の隙間が10mm以下に狭く形成されている部分を避けて、第2部分と所定側壁との間を通過するようになり、第1部分と所定側壁との間の部分の通過流量は低く抑えられる。これにより、所定側壁と風向案内羽根の第1部分との隙間を通過した空気流れは、風速が小さく抑えられている。このため、複数の風向案内羽根のうち左右方向の端部に位置する風向案内羽根よりも内側に位置している風向案内羽根が形成した左右方向へ広がろうとする調和空気の流れは、上記所定側壁と風向案内羽根の第1部分との隙間を通過した空気流れによる影響を受けにくくなっており、左右方向への広がりが遮られる程度が小さく抑えられている。これにより、従来のように吹出口の左右の側壁を、室内側(空気流れを直進させた場合の進行方向)に長く伸ばした形状を採用しなくても、調和空気を左右に広く届けることが可能になっており、装置の大型化を回避することができている。さらに、このように所定側壁と風向案内羽根の第1部分との間の隙間が10mm以下となるような狭い部分の近くにおいて、所定側壁と風向案内羽根の第2部分との間の隙間が10mm以上に広く形成されているため、調和空気はこの広い部分に導かれ、所定側壁と風向案内羽根との間を通過する調和空気の圧力損失を抑えることが可能になっている。
以上により、吹き出される調和空気の圧力損失を小さく抑えつつ、調和空気を左右方向へより広く届けることが可能になっている。 Further, the state that “the gap between the first portion and the predetermined side wall is 10 mm or less” is not particularly limited as long as the closest distance between the first portion and the predetermined side wall is 10 mm or less. A state where the closest distance is 8 mm or less, a state where the closest distance is 5 mm or less, a state where the closest distance is 4 mm, a state where the first portion and the predetermined side wall are in contact with each other, etc. Is included.
In this air conditioning indoor unit, the conditioned air that is blown out does not easily pass through a portion where the gap between the predetermined side wall and the first portion of the wind direction guide vane is 10 mm or less, and the gap between the predetermined side wall is 10 mm. It passes mainly through the larger part. For this reason, when the conditioned air blown out passes between the predetermined side wall and the wind direction guide vane, “the gap between the first part of the wind direction guide vane and the predetermined side wall is formed narrowly to 10 mm or less. It is unlikely that “the flow velocity is increased by passing through the portion”. Rather, the conditioned air that is blown out passes between the second part and the predetermined side wall, avoiding the part where the gap between the first part of the wind guide vane and the predetermined side wall is narrowly formed to be 10 mm or less. Thus, the passage flow rate of the portion between the first portion and the predetermined side wall is kept low. As a result, the air flow that has passed through the gap between the predetermined side wall and the first portion of the wind direction guide vane has a reduced wind speed. For this reason, the flow of conditioned air that is going to spread in the left-right direction formed by the wind direction guide vanes located inside the wind direction guide vanes located at the ends in the left-right direction among the plurality of wind direction guide vanes is It is less affected by the air flow that has passed through the gap between the side wall and the first portion of the wind direction guide vane, and the extent to which the spread in the left-right direction is blocked is kept small. As a result, it is possible to deliver conditioned air widely to the left and right without adopting a shape in which the left and right side walls of the air outlet are extended to the indoor side (the direction of travel when the air flow is straight) as in the past. This is possible, and the enlargement of the apparatus can be avoided. Further, in the vicinity of such a narrow portion where the gap between the predetermined side wall and the first portion of the wind direction guide vane is 10 mm or less, the gap between the predetermined side wall and the second portion of the wind direction guide vane is 10 mm. Since it is formed widely as described above, the conditioned air is guided to this wide portion, and the pressure loss of the conditioned air passing between the predetermined side wall and the wind direction guide vane can be suppressed.
As described above, the conditioned air can be delivered more widely in the left-right direction while suppressing the pressure loss of the conditioned air blown out.
この空調室内機では、このように吹出口の中心部分において、風向案内羽根の第1部分と所定側壁との間の10mm以下の狭い隙間が採用されている。このため、吹出口の中央付近における調和空気の風速を効果的に低減させることができる。これにより、風向案内羽根のうちより内側に位置しているものが形成した左右方向へ広がろうとする調和空気の流れが、上記所定側壁と風向案内羽根の第1部分との間の隙間を通過した速い風速で直進する空気流れによって阻害されることを抑制できている。これにより、左右方向への広がりが遮られる程度をより効果的に小さく抑え、左右方向への調和空気の広がりをより確実に確保することが可能になる。 In the air conditioning indoor unit, the wind speed of the conditioned air flowing near the center of the air outlet is faster than the wind speed of the conditioned air flowing along the wall surface by the amount of friction.
In this air conditioning indoor unit, a narrow gap of 10 mm or less between the first portion of the wind direction guide vane and the predetermined side wall is employed in the central portion of the air outlet in this way. For this reason, the wind speed of the conditioned air in the vicinity of the center of the outlet can be effectively reduced. As a result, the flow of conditioned air, which is formed on the inner side of the wind direction guide vanes and is going to spread in the left-right direction, passes through the gap between the predetermined side wall and the first portion of the wind direction guide vanes. It is possible to suppress obstruction by the air flow that goes straight at the high wind speed. As a result, the extent to which the spread in the left-right direction is blocked can be more effectively reduced, and the spread of the conditioned air in the left-right direction can be more reliably ensured.
なお、ここでは、左端の風向案内羽根と右端の風向案内羽根のみが長羽根である場合に限定されるものではない。例えば、左端の風向案内羽根と短羽根との間、および/または、右端の風向案内羽根と短羽根との間においてさらに長羽根が設けられていてもよい。また、左端の風向案内羽根と短羽根との間、および/または、右端の風向案内羽根と短羽根との間において、長羽根と短羽根との中間の大きさの風向案内羽根が設けられていてもよい。
この空調室内機では、内側に設けられている短羽根よりも、空気流れが沿う部分の長さが長い長羽根が左右方向の両端に設けられている。このため、所定側壁との間の隙間を10mm以下にすることが可能となるように風向案内羽根が設けられている場合には、風向案内羽根の全てが短羽根の長さで統一されている場合と比較して、合計の羽根の枚数を少なく抑えることができる。なお、これにより、全ての風向案内羽根による圧力損失の合計値を小さく抑えることも可能になる。 The air conditioning indoor unit according to the third aspect is the air conditioning indoor unit according to the first aspect or the second aspect, in which the plurality of wind direction guide blades are longer than the long blades located at both ends in the left-right direction. And a short blade having a short length of the portion along the air flow.
In addition, it is not limited here when only the wind direction guide blade | wing of a left end and the wind direction guide blade | wing of a right end are long blades. For example, a long blade may be further provided between the wind direction guide blade and the short blade at the left end and / or between the wind direction guide blade and the short blade at the right end. In addition, a wind direction guide blade having a size intermediate between the long blade and the short blade is provided between the wind direction guide blade and the short blade at the left end and / or between the wind direction guide blade and the short blade at the right end. May be.
In this air conditioner indoor unit, long blades are provided at both ends in the left-right direction in which the length of the portion along the air flow is longer than the short blades provided inside. For this reason, when the wind direction guide blades are provided so that the gap between the predetermined side walls can be 10 mm or less, all of the wind direction guide blades are unified with the length of the short blades. Compared to the case, the total number of blades can be reduced. This also makes it possible to reduce the total pressure loss due to all wind direction guide vanes.
この空調室内機では、膨出曲面が生じさせるコアンダ効果によって、風向案内羽根のうちより内側に位置している風向案内羽根が形成した左右方向へ広がろうとする調和空気の流れを、左右方向によりいっそう広げることが可能になる。 The air conditioning indoor unit according to the fourth aspect is the air conditioning indoor unit according to any of the first to third aspects, wherein the casing extends from the vicinity of the outlet of the outlet flow channel to the left and right, and is directed toward the main flow direction of the air flow. It has a bulging curved surface with a gently bulging shape. The main flow direction refers to the main flow of the air flow that occurs when the wind direction is not adjusted for the air flow that occurs along the blowout flow path.
In this air-conditioning indoor unit, the flow of conditioned air that spreads in the left-right direction formed by the wind direction guide blades located on the inner side among the wind direction guide blades, due to the Coanda effect that causes the bulging curved surface, It becomes possible to expand further.
この空調室内機では、膨出高さが低く抑えられているため、室内側の空気が吹出口の左右の側壁に向かって流れ込むことを抑制できる。 The air conditioner indoor unit according to the fifth aspect is the air conditioner indoor unit according to the fourth aspect, wherein the bulge height of the bulge curved surface in the main flow direction of the air flow is determined by the left and right side walls of the blowout flow path and the left and right side surfaces of the casing. Is less than half of the thickness between. Here, the thickness between the left and right side walls of the blowing channel and the left and right side surfaces of the casing may be, for example, the thickness in the vicinity of the outlet of the blowing channel. Moreover, the bulging height of the bulging curved surface is, for example, preferably 20 mm or less, and more preferably 10 mm or less.
In this air conditioning indoor unit, since the bulging height is kept low, it is possible to suppress the air on the indoor side from flowing toward the left and right side walls of the outlet.
この空調室内機では、所定側壁と膨出曲面とは、なだらかに繋がっていることで、調和空気の流れがケーシングの表面から離れにくくして、コアンダ効果をより確実に得ることが可能になっている。また、所定側壁と膨出曲面とが繋がっている部分の湾曲度合いは、膨出曲面における湾曲度合いよりも大きな湾曲度合いとなっているため、吹出流路の出口を、十分に左右に広げることができている。これにより、調和空気の流れが膨出曲面から剥がれることを抑制しつつ、左右方向によりいっそう広く調和空気を供給することが可能になる。 In the air conditioning indoor unit pertaining to the sixth aspect, in the air conditioning indoor unit pertaining to the fourth aspect or the fifth aspect, the predetermined side wall and the bulging curved surface are smoothly connected with a degree of curvature greater than the degree of curvature of the bulging curved surface. . Here, the large degree of curvature includes, for example, a small curvature radius.
In this air conditioning indoor unit, the predetermined side wall and the bulging curved surface are smoothly connected, so that the flow of conditioned air is less likely to be separated from the surface of the casing, and the Coanda effect can be obtained more reliably. Yes. In addition, the degree of curvature of the portion where the predetermined side wall and the bulging curved surface are connected is larger than the degree of curvature of the bulging curved surface, so that the outlet of the blowing channel can be sufficiently expanded to the left and right. is made of. Thereby, it becomes possible to supply conditioned air more widely in the left-right direction while suppressing the flow of conditioned air from peeling from the bulging curved surface.
この空調室内機では、吹出流路から流出した調和空気を、より確実に左右に案内させることが可能になる。 The air conditioning indoor unit pertaining to the seventh aspect is the air conditioning indoor unit pertaining to any of the fourth to sixth aspects, further comprising ribs protruding from the bulging curved surface and extending in the left-right direction.

この空調室内機では、吹出流路から流出した調和空気は、その進行方向が強制的により左右方向に広がるように誘導板によって調節されるため、より確実に調和空気を左右に案内させることが可能になる。 An air conditioning indoor unit according to an eighth aspect is the air conditioning indoor unit according to any one of the first to seventh aspects, and is disposed on the downstream side of the outlet of the outlet flow path, along each of the left and right side walls of the outlet flow path. It further includes a guide plate that changes the flow direction and guides it to the left and right.

この湾曲面部80には、図2,図3、および、図5に示すように、左右方向の外側において湾曲面部80に垂直であってかつ左右方向に延びているガイドリブ81、82、83が形成されている。このガイドリブ81、82、83は、湾曲面部80の左右方向の中央近傍から外側曲面84の手前付近にかけて、互いに平行に伸びるように形成されている。また、これらのガイドリブ81、82、83は、前後方向に等間隔に配置されている。 The

吹出流路8の上流側の本体ケーシング5内部には、クロスフローファンである室内ファン42が配置されており、この室内ファン42が制御部によって駆動制御されることで吹出流路8に空気流れが形成される。ここで、吹出風量は、6段階に調節可能であり、具体的には、水平フラップ45、外側垂直フラップ61および内側垂直フラップ62が最も通風抵抗が小さい姿勢となった状態で、小容量機であれば風速3~6m/s(大容量機であれば風速5~8m/s)の範囲内で、ユーザが選択できるようになっている。 The

水平フラップ45は、図示しない水平フラップ駆動機構によって、吹き出し空気流れの進行方向を上下に変更できるように姿勢が変更される。この水平フラップ45の姿勢の制御は、ユーザの設定を受けた制御部70によって行われる。この水平フラップ45は、図4の状態において、空気流れ下流側の面(室内側を向いた面)は、わずかに室内側に凸となるように湾曲して形成されている。
なお、水平フラップ45は、運転停止状態では、図4に示すように、吹出流路8の出口である吹出口を覆った状態になる。この状態では、水平フラップ45の前方の縁部は、フロントパネル5aの下縁と略平で概ね接した状態となり、側面視においてなだらかに繋がっているような状態になる。なお、水平フラップ45の背面側の縁部は、下面パネル5bの前方側縁部との間に僅かに隙間を確保しつつ、側面視においてなだらかに繋がっているような状態になる。 (2-2)

外側垂直フラップ61は、図2、図3に示すように、吹出流路8の右側面である第1側壁87および第2側壁89の最も近くに配置されている垂直フラップである。外側垂直フラップ61は、斜め前後方向(空気流れ方向(主流方向)に対して垂直な方向)を長手方向とする軸部材61xによって回転可能に軸支されている。なお、図示は省略するが、吹出流路8の左側面である第1側壁87および第2側壁89の最も近くにおいても、同様に外側垂直フラップ61が配置されている。
内側垂直フラップ62は、右側の外側垂直フラップ61と、左側の外側垂直フラップ61との間に複数枚配置されている。内側垂直フラップ62は、斜め前後方向を長手方向とする軸部材62xによって回転可能に軸支されている。 (2-3) Outer

外側垂直フラップ61および内側垂直フラップ62は、図1および図2に示すように、吹出流路8内の空気流れ方向(主流方向)に垂直な面において、吹出流路8の吹出背面8aと吹出前面8bとの間の中央部分61aが、最も風下側まで長く伸びるように形成されている。なお、外側垂直フラップ61の風下側の縁のうち、中央部分61aよりも吹出前面8b側である上方部分61bは、中央部分61aよりも空気流れ方向上流側に位置するように短く形成されている。外側垂直フラップ61の風下側の縁のうち、中央部分61aよりも吹出背面8a側である下方部分61cも同様に、中央部分61aよりも空気流れ方向上流側に位置するように短く形成されている。 The outer

各外側垂直フラップ61と各内側垂直フラップ62とは、吹出流路8内において、任意の角度に調整された状態で、いずれも、全体が膨出曲面85よりも風上側に位置するように配置されている。なお、図5において実線で示すように、各外側垂直フラップ61と各内側垂直フラップ62とが、左右方向に最も傾斜するように制御された状態では、吹出流路8の吹出口(左右の第1側壁87の風下側端部同士を結んだ面)よりも、全体が空気流れ方向上流側に位置している。上述したように、外側垂直フラップ61は、吹出背面8aと吹出前面8bとの間の真ん中部分が、最も長く伸びた形状となっているため、左右方向に最も傾斜するように制御された状態では、下流側の先端部分が吹出流路8の第1側壁87に最も近づくことになる。図5および図6に示すように、この状態で、外側垂直フラップ61の空気流れ方向下流側端部と、吹出流路8の第1側壁87との最近接距離d1は、10mm以下となるように、外側垂直フラップ61の位置が調節されている。 The outer

以上の構成の空調室内機4において、内部に収容されている室内ファン42が駆動すると、吹出流路8を通じて室内側に調和空気が吹き出される。
ここで、図6に示すように、調和空気の供給先が左右に最も広がるように、外側垂直フラップ61と内側垂直フラップ62とが調節されている場合には、図5に示すように、吹出流路8の第2側壁89を沿うように流れる空気流れF9は、吹出流路8の第1側壁87と外側垂直フラップ61の中央部分61aとの間が非常に狭くなっている(10mm以下に調節されている)ため、吹出背面8aと吹出前面8bの真ん中の部分を通過しようとする調和空気の流れは流速が低減される。ここで、風向が調節されずに調和空気が直進している状態では、空気流れF9のうち吹出背面8aと吹出前面8bの真ん中の部分において風速が最も速くなっている。上記構造は、この最も速い風速の空気流れを低く抑えることが可能になっている。この構造により、空気流れF9のうち吹出背面8aと吹出前面8bの真ん中の部分の通過が制限された流れは、第1側壁87との間の隙間がより広い部分である、外側垂直フラップ61の上方部分61bと第1側壁87との間の隙間や、下方部分61cと第1側壁87との間の隙間に向かうように導かれる。 (3) Air Flow In the air conditioning

(4)上記実施形態の特徴
(4-1)従来の問題点
例えば、図12に示すように、従来の空調室内機901では、吹出口の左右の側壁が下流側に長く伸びている場合(室内ファン942の下流側端部から距離d91の分だけ下流側に長い場合)には、吹出口の左右の下流側近傍において、収容物909(風向調節羽根の姿勢を変えるためのモータ、端子台、および、配線等の電装品)を収容するためのスペースを確保できる。しかし、内側の垂直フラップによって進行方向が左右に広がるように調節された空気流れF7は、下流側まで長く伸びた左右の側壁に衝突してしまい、左右方向に広がることができなくなっている。また、吹出口の左右の側壁と垂直フラップとの間のスペースが広いため、吹出流路の左右の側壁を沿うように流れる空気流れF91は、通過する風量が多いため、風速が速い。このため、内側の垂直フラップによって進行方向が左右に広がるように調節された空気流れF7は、この風速の速い空気流れF91によって、左右方向への広がりが阻害されてしまい、左右方向に広がりの無い空気流れF95にしてしまう。 The air flow F5 that tends to spread in the left-right direction is further guided in the left-right direction by
(4) Features of the above embodiment (4-1) Conventional problems For example, as shown in FIG. 12, in the conventional air conditioning
これに対して、上記実施形態の空調室内機4では、吹出流路8の第2側壁89を沿うように流れる空気流れF9のうち、直進時に風速が最も速くなる部分である吹出流路8の中央部分を通過する流れは、通過する隙間が狭くなるように(第1側壁87と外側垂直フラップ61の中央部分61aとが10mm以下に近づくように)調節されていることから、この狭い部分を避けて流れるようになり、通過風量が抑えられることで速度が低減されている。このため、空気流れF9は、内側垂直フラップ62によって進行方向が左右方向に広げられた空気流れF3を阻害しにくい。このため、内側垂直フラップ62によって進行方向が左右方向に広がるように曲げられた空気流れF3は、そのまま左右方向に広がっていくことができている。また、この場合であっても、外側垂直フラップ61の上方部分61bおよび下方部分61cは、吹出流路8の第1側壁87との隙間がより広く確保されているため、圧力損失が増大し過ぎることがない。 (4-2) Solution of problems caused by the air conditioning
そして、上記実施形態の湾曲面部80は、外側垂直フラップ61および内側垂直フラップ62の風下側端部まで伸びている。また、上述の構造によって調和空気を左右方向に広げることができているため、図13で示す従来の例のようにコアンダ効果を十分確保するために空気流れが沿って流れる湾曲面を長く設ける必要が無く、膨出高さh1を短くすることができている。このため、収容物を収容するためのスペースを確保することができるとともに、装置が大型化し過ぎてしまうことを避けることができている。
なお、上記外側垂直フラップ61は、内側垂直フラップ62よりも空気流れ方向(主流方向)の長さが長く構成されている。これにより、垂直フラップの全てを内側垂直フラップ62と同じもので統一した場合と比較して、第1側壁87との隙間を小さく抑えるために必要となる垂直フラップの合計枚数を少なく抑えることが可能になっている。 In addition, by generating the air flow that spreads in the left-right direction, it is possible to suppress unbalanced air flowing in from the indoor side as described in the example of FIG. 12, and it is possible to suppress the occurrence of surging and condensation.
