　本実施の形態によれば、吹出しパネル２０の吹出口２１を構成する壁面のうち、径方向外側壁面２１１は、案内部２１１１と、案内部２１１１から外部へ伸びる付着部２１１２と、を有する。案内部２１１２の上下方向に沿って切断した断面形状は、鉛直線である。付着部２１１２の上下方向に沿って切断した断面形状は、吹出口２１の径方向内側に向かって突出した弧形状である。そのため、図７に示すように、案内部２１１１による作用で、吹き出された気流は、気流が吹出口２１内において乱流にならないように、吹出口２１からスムーズに導出され、吹き出し気流による快適性を向上させる。 According to the present embodiment, among the wall surfaces constituting the air outlet 21 of the blowout panel 20, the radial outer wall surface 211 has a guide portion 2111 and an adhesion portion 2112 extending from the guide portion 2111 to the outside. The cross-sectional shape of the guide portion 2112 cut in the vertical direction is a vertical line. The cross-sectional shape of the attached portion 2112 cut in the vertical direction is an arc shape that protrudes inward in the radial direction of the air outlet 21. Therefore, as shown in FIG. 7, the air flow blown out by the action of the guide portion 2111 is smoothly derived from the blowout port 21 so that the air flow does not become turbulent in the blowout port 21, and the comfort by the blowout air flow Improve.
　さらに、付着部２１１２は、案内部２１１１から外部へ滑らかに延伸するものである。このため、吹出し気流は、案内部２１１１に沿って、付着部２１１２に滑らかに流れるようになる。具体的には、コアンダ効果による。付着部２１１２の上下方向に沿って切断した断面形状全体は、吹出口２１の径方向内側に向かって突出した弧形状である。吹出し気流は、上記径方向内側へ突出した弧形状の、案内部２１１１に接近した部分による作用で、まず前方且つ下方に向かって流れる。そして、上記径方向内側へ突出した弧形状の、案内部２１１１から離れた部分による作用で、天井板の方向に沿って流れる。これによって、冷房運転モードでの送風効果を確保することができるほか、吹出し気流に含まれる微小な粒子が天井板に吸着して天井板が汚れてしまうことを抑制することができる。 Furthermore, the attached portion 2112 is one that smoothly extends from the guide portion 2111 to the outside. For this reason, the blowout air flow smoothly flows to the attachment portion 2112 along the guide portion 2111. Specifically, it depends on the Coanda effect. The entire cross-sectional shape of the attached portion 2112 cut in the vertical direction is an arc shape projecting radially inward of the air outlet 21. The blowout air stream first flows forward and downward due to the action of the portion of the arc shape projecting radially inward and approaching the guide portion 2111. And it flows along the direction of a ceiling board by the effect | action by the part away from the guide part 2111 of the arc shape which protruded to said radial inside. Thus, the air blowing effect in the cooling operation mode can be secured, and moreover, it is possible to suppress that the minute particles contained in the blowing air flow are adsorbed to the ceiling plate and the ceiling plate is soiled.
　また、本実施の形態によれば、外縁枠部２２の上部と付着部２１１２の下端との間の上下方向の距離Ｈが、１０ｍｍ以上となっている。このため、空調室内機の取り付け状態で外縁枠部２２の上部を天井板に当接させることにより、上下方向において天井板と付着部２１１２の下端との距離が１０ｍｍ以上になる。これによって、吹出し気流は、付着部２１１２による作用で、まず前方且つ下方に向かって流れ、そして、水平方向に沿って流れるようになる。気流が上下方向において拡散してしまった場合でも、天井板とは一定の距離を置いていることになる。これによって、吹出口２１から吹き出された気流が天井板に張り付くように流れることを効果的に避けることができ、天井板が吹き出し気流に含まれる埃によって汚れてしまうことが抑制される。 Further, according to the present embodiment, the distance H in the vertical direction between the upper portion of the outer edge frame portion 22 and the lower end of the attachment portion 2112 is 10 mm or more. For this reason, the distance between the ceiling plate and the lower end of the attachment portion 2112 in the vertical direction becomes 10 mm or more by bringing the upper portion of the outer rim portion 22 into contact with the ceiling plate in the mounted state of the air conditioning indoor unit. As a result, the blowout air flow first flows forward and downward and flows along the horizontal direction by the action of the attachment portion 2112. Even when the air flow is diffused in the vertical direction, the ceiling plate is at a fixed distance. As a result, the air flow blown out from the air outlet 21 can be effectively prevented from flowing so as to stick to the ceiling plate, and contamination of the ceiling plate by dust contained in the blow air can be suppressed.
　また、本実施の形態によれば、外縁枠部２２の、吹出しパネル２０の底端から径方向外側に向かって上向きに傾斜して延伸する傾斜面２２１と水平面のなす角度γが、０°＜γ≦６０°を満たす。これによって、角度γを６０°よりも大きくする場合と比べると、吹出口２１から吹き出された気流が天井板に直接当たることを効果的に避けることができ、天井板が吹き出し気流に含まれる埃によって汚れてしまうことが抑制される。また、傾斜面２２１によっては、視覚効果によって吹出しパネル２０と天井板との高度差が減り、吹出しパネル２０と天井板との組み合わせの見栄えを向上させることができる。 Further, according to the present embodiment, the angle γ between the horizontal surface and the inclined surface 221 of the outer edge frame portion 22 that extends obliquely upward and outward from the bottom end of the blowout panel 20 is 0 ° < It satisfies γ ≦ 60 °. By this, compared with the case where the angle γ is made larger than 60 °, it is possible to effectively prevent the air flow blown out from the air outlet 21 from directly hitting the ceiling plate, and the dust is included in the air flow It is suppressed that it gets dirty. Further, depending on the inclined surface 221, the difference in height between the blowout panel 20 and the ceiling plate may be reduced by the visual effect, and the appearance of the combination of the blowout panel 20 and the ceiling plate can be improved.
　また、本実施の形態によれば、空調室内機１の冷房運転時、１５°≦α≦６０°という条件を満たすように、導風フィン４０の回動角度を制御することにより、導風フィン４０と吹出口２１の内側壁との間に、先が細くなる気流通路が形成される。このことは、気流の流動速度を高めて主気流を形成することに寄与する。吹出し気流は、付着部２１１２による作用で、まず、前方且つ下方に流れ、そして、天井板の方向に沿って流れるようになる。 Further, according to the present embodiment, the air guide fin is controlled by controlling the turning angle of the air guide fin 40 so as to satisfy the condition of 15 ° ≦ α ≦ 60 ° during the cooling operation of the air conditioning indoor unit 1. An air flow passage having a tapered end is formed between 40 and the inner wall of the air outlet 21. This contributes to the formation of the main air flow by increasing the flow velocity of the air flow. The blowout air stream first flows forward and downward and then flows along the direction of the ceiling plate by the action of the attachment portion 2112.
　また、本実施の形態によれば、空調室内機１の冷房運転時、０ｍｍ≦Ｄ≦３５ｍｍ（具体的には、導風フィンの下端は、付着部の下端の上方に位置する）という条件を満たすように、導風フィン４０の回動角度を制御する。これにより、導風フィン４０と付着部２１１２とが相互に協働するようになる。 Further, according to the present embodiment, the condition that 0 mm ≦ D ≦ 35 mm (specifically, the lower end of the air guide fin is located above the lower end of the adhering portion) during the cooling operation of the air conditioning indoor unit 1 The turning angle of the air guide fin 40 is controlled so as to satisfy the condition. Thereby, the air guide fins 40 and the attachment portion 2112 cooperate with each other.
　また、本実施の形態によれば、空調室内機１の冷房運転時、１０ｍｍ≦Ｌ≦４０ｍｍという条件を満たすように、導風フィン４０の回動角度を制御する。これにより、吹出し気流は、導風フィン４０と吹出口２１の内側壁との間に形成された気流通路を流れ、流動速度が向上し、付着部２１１２によるコアンダ効果を確保することに寄与する。 Further, according to the present embodiment, the turning angle of the air guide fin 40 is controlled so as to satisfy the condition of 10 mm ≦ L ≦ 40 mm during the cooling operation of the air conditioning indoor unit 1. As a result, the blow-off air flows through the air flow passage formed between the air guide fins 40 and the inner side wall of the blowout port 21, the flow speed is improved, and the Coanda effect by the adhering portion 2112 is contributed.
　特に、空調室内機１の冷房運転時、１５°≦α≦６０°、１０ｍｍ≦Ｌ≦４０ｍｍ、０ｍｍ≦Ｄ≦３５ｍｍという各関係式を同時に満たすように、導風フィン４０の回動角度を制御することによって、吹出口２１から吹き出された気流が天井板に直接当たることを効果的に避けることができる。また、気流が直下に吹き出されることを抑制できる。さらに、コアンダ効果により、吹出し気流がまず前方且つ下方に向かって流れ、そして、水平方向に流れることが確保される。これにより、送風量が確保され、快適性が向上する。 In particular, during the cooling operation of the air conditioning indoor unit 1, the rotational angle of the air guide fin 40 is controlled so as to simultaneously satisfy the relational expressions 15 ° ≦ α ≦ 60 °, 10 mm ≦ L ≦ 40 mm, 0 mm ≦ D ≦ 35 mm. By doing this, it is possible to effectively prevent the air flow blown out from the air outlet 21 from directly hitting the ceiling plate. Moreover, it can suppress that an air flow blows off directly under. Furthermore, the Coanda effect ensures that the blow-off air flows first forward and downward and then horizontally. Thereby, the air flow rate is secured and the comfort is improved.
　また、本実施の形態によれば、０°＜β≦６０°を満たしているので、吹出し気流は、径方向内側へ突出した弧形状の、案内部２１１１に接近した部分による作用で、まず、前方且つ下方に向かって流れる。そして、径方向内側へ突出した弧形状の、案内部２１１１から離れた部分による作用で、水平方向へ流れる。そうすると、冷房運転モードでの送風効果を確保することができ、さらに、吹出し気流に含まれる微小な粒子が天井板に吸着されて天井板が汚れてしまうことも抑制できる。 Further, according to the present embodiment, 0 ° <β ≦ 60 ° is satisfied, so that the blowout air flow is first of all due to the action of the arc shape projecting radially inward and in the portion close to the guide portion 2111. It flows forward and downward. Then, it flows in the horizontal direction by the action of the portion of the arc shape projecting radially inward and away from the guide portion 2111. Then, the air blowing effect in the cooling operation mode can be secured, and furthermore, it can be suppressed that the minute particles contained in the blowing air flow are adsorbed to the ceiling plate and the ceiling plate is soiled.
　＜実施の形態２＞
　以下、図８と図９を参照しながら、本発明における空調室内機の実施の形態２を説明する。本実施の形態は、上記実施の形態１と基本的に同じであるが、吹出しパネルの構造が相違する。 Second Embodiment
Hereinafter, Embodiment 2 of the air conditioning indoor unit in the present invention will be described with reference to FIGS. 8 and 9. The present embodiment is basically the same as Embodiment 1 described above, but differs in the structure of the blowing panel.
　ここでは、上記実施の形態１と同じ部材に対して同一の符号を付加し、相違点を中心として説明する。 Here, the same reference numerals are added to the same members as those in the first embodiment, and the description will be made centering on differences.
　図８に示すように、吹出しパネル２０は、外縁枠部２２を有する。外縁枠部２２は、ケース１０に固定された固定部ＧＤと、固定部ＧＤに対して開放可能な可動部ＫＤとを有する。可動部ＫＤは、付着部２１１２を有する。 As shown in FIG. 8, the blowout panel 20 has an outer rim 22. The outer edge frame portion 22 has a fixed portion GD fixed to the case 10 and a movable portion KD openable to the fixed portion GD. The movable portion KD has an attached portion 2112.
　また、フィルター７０は、一体に形成されたものではなく、少なくとも一部（例えば、図８の左側の部分）が、他の部分とは別に、ケース１０から取り外し可能である。 Also, the filter 70 is not integrally formed, and at least a portion (e.g., the portion on the left side of FIG. 8) is removable from the case 10 separately from the other portions.
　また、固定部ＧＤは、フィルター７０（の少なくとも一部）の取り出しが可能なサイズの開口部ＫＫを有する。 In addition, the fixed portion GD has an opening KK of a size that allows removal of (at least a part of) the filter 70.
　ここで、可動部ＫＤは、開口部ＫＫの内部に回動可能に設けられた可動板である。 Here, the movable portion KD is a movable plate rotatably provided inside the opening portion KK.
　また、制御部９０は、可動部ＫＤの回動を制御する。 The control unit 90 also controls the rotation of the movable portion KD.
　本実施の形態によれば、基本的に上記実施の形態と同じ技術的効果を奏することができる。 According to the present embodiment, basically the same technical effect as the above embodiment can be obtained.
　また、本実施の形態によれば、空調室内機の運転時、図９に示すように、制御部９０を用いて、開口部ＫＫを開放させる位置まで可動部ＫＤを回動させる。これにより、図８に示すような、開口部ＫＫを閉じる位置に可動部ＫＤが位置する場合と比べて、付着部２１１２の、可動部ＫＤの回動中心から離れた一端を、より下方に位置させることができる。即ち、付着部２１１２の下端と天井板との距離が増加する。付着部２１１２による作用で、吹出し気流は、天井板との間で一定の距離を保つことになる。これによって、吹出口２１から吹き出された気流が天井板に直接当たることをより効果的に避けることができ、天井板が吹き出し気流に含まれるダストによって汚れてしまうことが抑制される。 Further, according to the present embodiment, at the time of operation of the air conditioning indoor unit, as shown in FIG. 9, the control unit 90 is used to rotate the movable portion KD to a position at which the opening portion KK is opened. Thereby, as compared with the case where the movable part KD is located at the position closing the opening KK as shown in FIG. 8, one end of the attached part 2112 away from the rotation center of the movable part KD is positioned further downward. It can be done. That is, the distance between the lower end of the attached portion 2112 and the ceiling plate is increased. By the action of the adhesion portion 2112, the blowout air flow is kept at a constant distance from the ceiling plate. By this, it is possible to more effectively prevent the air flow blown out from the blowout port 21 from directly hitting the ceiling plate, and it is possible to suppress that the ceiling plate is contaminated by dust contained in the blowing air flow.
　また、本実施の形態によれば、空調室内機の運転時、図９に示すように、制御部９０を用いて、開口部ＫＫを開放させる位置まで可動部ＫＤを回動させる。これにより、開口部ＫＫを介して、ケース１０に取り付けられたフィルター７０（の少なくとも一部）へのメンテナンスが行いやすくなる。例えば、ケース１０に取り付けられたフィルター７０を取り外して洗浄し、その後、ケース１０に取り付けることができる。 Further, according to the present embodiment, at the time of operation of the air conditioning indoor unit, as shown in FIG. 9, the control unit 90 is used to rotate the movable portion KD to a position at which the opening portion KK is opened. This makes it easy to perform maintenance on (at least a part of) the filter 70 attached to the case 10 through the opening KK. For example, the filter 70 attached to the case 10 can be removed and cleaned, and then attached to the case 10.
　＜実施の形態３＞
　以下、図１０と図１１を参照しながら、本発明における空調室内機の実施の形態３を説明する。本実施の形態は、上記実施の形態１と基本的に同じであるが、吹出しパネルの構造が相違する。 Embodiment 3
Hereinafter, Embodiment 3 of the air conditioning indoor unit in the present invention will be described with reference to FIG. 10 and FIG. The present embodiment is basically the same as Embodiment 1 described above, but differs in the structure of the blowing panel.
　ここでは、上記実施の形態と同じ部材に対して同一の符号を付加し、相違点を中心として説明する。 Here, the same reference numerals are added to the same members as those in the above embodiment, and the description will be made centering on differences.
　図１０に示すように、吹出しパネル２０は、外縁枠部２２を有する。外縁枠部２２は、ケース１０に固定された固定部ＧＤＡと、固定部ＧＤＡに対して昇降可能な可動部ＫＤＡ
とを有する。可動部ＫＤＡは、付着部２１１２を有する。 As shown in FIG. 10, the blowout panel 20 has an outer rim 22. The outer edge frame portion 22 has a fixed portion GDA fixed to the case 10 and a movable portion KDA which can move up and down with respect to the fixed portion GDA.
And. The movable part KDA has an attached part 2112.
　ここで、図示されていないが、空調室内機は、昇降駆動機構をさらに備える。昇降駆動機構は、モータと、ラックピニオン機構とを有する。ラックピニオン機構は、モータによる動力を可動部ＫＤＡに伝達し、その可動部ＫＤＡを昇降させる。 Here, although not shown, the air conditioning indoor unit further includes a lifting drive mechanism. The elevation drive mechanism has a motor and a rack and pinion mechanism. The rack and pinion mechanism transmits the power of the motor to the movable part KDA, and raises and lowers the movable part KDA.
　本実施の形態によれば、基本的に上記実施の形態と同じ技術的効果を奏することができる。 According to the present embodiment, basically the same technical effect as the above embodiment can be obtained.
　また、本実施の形態によれば、空調室内機の運転時、図１１に示すように、制御部９０を用いて可動部ＫＤＡを下降させることにより、図１０に示すような可動部ＫＤＡが上昇している場合と比べて、付着部２１１２の底端を、より下方に位置させることができる。これによって、吹出口２１から吹き出された気流が天井板に直接当たることを、より効果的に避けることができる。 Further, according to the present embodiment, at the time of operation of the air conditioning indoor unit, as shown in FIG. 11, the movable portion KDA as shown in FIG. 10 is raised by lowering the movable portion KDA using the control unit 90. The bottom end of the attachment portion 2112 can be positioned lower than in the case where it is carried out. By this, it can be more effectively avoided that the air flow blown out from the blower outlet 21 hits the ceiling plate directly.
　以上、添付図面によって、本発明を例示的に説明したが、本発明の具体的な実現は、上記実施の形態だけに限られないことは明らかである。 Although the present invention has been described by way of example with reference to the accompanying drawings, it is clear that the specific realization of the present invention is not limited to the above embodiment.
　例えば、上記実施の形態では、付着部２１１２の上下方向に沿って切断した断面形状が、曲率半径が一定な円弧である。しかし、そのような断面形状に限らず、付着部２１１２の上下方向に沿って切断した断面形状は、曲率半径が異なる複数の円弧が接続された形状であってもよい。また、その場合、好ましくは、複数の円弧のうち、外側の円弧は、内側（ケース側）の円弧よりも、曲率半径が大きくなる。そのような構造によれば、吹出口２１から吹き出された気流が天井板に直接当たることを、より効果的に避けることができる。 For example, in the above embodiment, the cross-sectional shape of the attached portion 2112 cut in the vertical direction is a circular arc having a constant radius of curvature. However, not limited to such a cross-sectional shape, the cross-sectional shape cut along the up and down direction of the attached portion 2112 may be a shape in which a plurality of arcs having different radii of curvature are connected. In that case, preferably, among the plurality of arcs, the outer arc has a larger radius of curvature than the inner (case side) arc. According to such a structure, it is possible to more effectively avoid that the air flow blown out from the air outlet 21 directly hits the ceiling plate.
　また、上記実施の形態では、案内部２１１１は、上下方向に平行な鉛直壁面と上下方向に対して傾斜した傾斜面とで形成されている。しかし、それに限らず、案内部は、上下方向に対して傾斜した傾斜面のみで形成されてもよい。その場合、付着部と導風フィンとが協働して、ファンから吹き出された気流を、付着部に沿って径方向外側に案内するような冷房運転モードにおいて、上記実施の形態と同じように、好ましくは、１５°≦α≦６０°を満たし、好ましくは、１０ｍｍ≦Ｌ≦４０ｍｍを満たし、好ましくは、０ｍｍ≦Ｄ≦３５ｍｍを満たす。 Further, in the above embodiment, the guide portion 2111 is formed of a vertical wall surface parallel to the vertical direction and an inclined surface inclined to the vertical direction. However, the invention is not limited thereto, and the guide portion may be formed only by an inclined surface which is inclined with respect to the vertical direction. In that case, in the cooling operation mode in which the adhesion portion and the air guide fin cooperate to guide the air flow blown out from the fan radially outward along the adhesion portion as in the above embodiment. Preferably, 15 ° ≦ α ≦ 60 ° is satisfied, preferably 10 mm ≦ L ≦ 40 mm, and preferably 0 mm ≦ D ≦ 35 mm.
　また、上記実施の形態において、暖房運転モードでは、導風フィンが反転され、０ｍｍ≦Ｄ≦３５ｍｍを満たすことが好ましく、導風フィンの下端が付着部の下方に位置するようにしてもよい。そうすると、ファンから吹き出された気流を、さらに下向きに案内させることに寄与し、迅速な加熱を実現する。これにより、快適性を確保しながら、吹出しパネルの高さ寸法を増加しないようにすることができる。 Further, in the above embodiment, in the heating operation mode, the air guide fin is inverted to preferably satisfy 0 mm ≦ D ≦ 35 mm, and the lower end of the air guide fin may be positioned below the adhesion portion. This contributes to guiding the air flow blown out from the fan further downward, thus achieving rapid heating. Thus, the height dimension of the blowout panel can be prevented from increasing while securing the comfort.
　また、図示されていないが、案内部は、曲面で形成されてもよいし、または、上下方向に平行な鉛直壁面と、上下方向に対して傾斜した傾斜面との、少なくとも一方及び曲面で形成されてもよい。 Further, although not shown, the guide portion may be formed by a curved surface, or formed by at least one of a vertical wall parallel to the vertical direction and an inclined surface inclined with respect to the vertical direction and a curved surface. It may be done.
　また、ファン３０は、軸流ファンに限られない。 Also, the fan 30 is not limited to the axial fan.
