Description

【０００１】
【発明の属する技術分野】
この発明は、吹出口に複数の垂直羽根を有する空気調和機の吹出口構造に関する。
【０００２】
【従来の技術】
従来、空気調和機の吹出口構造としては、吹出口に横方向に配列された平板状の複数の垂直羽根を有するものがある。この空気調和機の吹出口構造は、複数の垂直羽根を連結部材に回動自在に連結し、各垂直羽根を水平方向に傾けて、風向を水平方向に制御している。しかしながら、上記平板状の垂直羽根では、垂直羽根の水平方向の傾きが大きくなるほど、垂直羽根に沿って空気がスムーズに流れず、垂直羽根の下流側の空気流が乱れて、圧力損失が増大するという欠点がある。
【０００３】
そこで、図５に示すように、上流側硬質部５１と、下流側硬質部５２と、上記両硬質部５１，５２の中間の湾曲可能な軟質部５３とからなる垂直羽根５０を備えた空気調和機の吹出口構造が提案されている（特開平４−１３０４０号公報）。この空気調和機の吹出口構造は、図６に示すように、垂直羽根５０の下流側硬質部５２上端に設けられた凹部５４を上側吹出口本体６１の図示しない凸部に回転自在に嵌合すると共に、垂直羽根５０の下流側硬質部５２下端に設けられた凸部５５を下側吹出口本体６２の図示しない凹部に回転自在に嵌合して、複数の垂直羽根５０，５０，…（図６では２つのみを示す）を吹出口に横方向に配列している。そして、上記複数の垂直羽根５０，５０，…の上流側硬質部５１の下端に設けられた図５に示す切り欠き５１ａに連結部材６３を嵌合して、複数の垂直羽根５０，５０，…を互いに連結している。図７は図６の垂直羽根５０，５０，…と連結部材６３を上方から見た上面図を示し、垂直羽根５０，５０，…は、矢印の吹出方向に沿って略平行な状態にある。そして、図８に示すように、上記連結部材６３を矢印Ｒの方向に移動させることによって、上記複数の垂直羽根５０，５０，…の各軟質部５３を湾曲させて、吹出方向を図中左下方向に調整する。こうして、湾曲した複数の垂直羽根５０，５０，…に沿って空気がスムーズに流れて、圧力損失を低減し、水平方向の気流制御が行われる。
【０００４】
【発明が解決しようとする課題】
ところで、上記湾曲可能な複数の垂直羽根５０，５０，…を備えた空気調和機の吹出口構造では、水平羽根なしに風向を上下方向に制御することができない。また、上記複数の垂直羽根５０，５０，…の下流側に位置するように水平羽根を設けた場合、下流側の水平羽根による上下方向の気流制御が支配的なため、複数の垂直羽根５０，５０，…による水平方向の気流制御が十分に機能しないという問題がある。また、上記水平羽根が上下方向に傾動して、空気流に対する水平羽根の翼面の傾きが大きくなるほど、垂直羽根により水平方向に曲げられた空気流が水平羽根に上下方向の速度成分を持たずに衝突して、水平羽根による圧力損失が大きくなって、空気流の到達距離が短くなるという問題がある。
【０００５】
そこで、この発明の目的は、水平方向と上下方向の気流制御を圧力損失を低減して行うことができ、空気流の到達距離を大きくできる空気調和機の吹出口構造を提供することにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するため、請求項１の空気調和機の吹出口構造は、吹出口本体に固定された上流側硬質部と、下流側硬質部と、上記上流側硬質部と上記下流側硬質部との中間の湾曲可能な軟質部とからなる複数の垂直羽根と、上記複数の垂直羽根の上記下流側硬質部の上端に回動自在に連結した第１連結部材と、上記複数の垂直羽根の上記下流側硬質部の下端に回動自在に連結した第２連結部材とを備えて、上記第１連結部材と上記第２連結部材とによって上記複数の垂直羽根の上記軟質部をねじることができるようにしたことを特徴としている。
【０００７】
上記請求項１の空気調和機の吹出口構造によれば、上記第１，第２連結部材を同一方向に同一量だけ移動させると、複数の垂直羽根の上流側硬質部を吹出口本体に固定しているので、第１，第２連結部材に連動して、軟質部が湾曲しながら下流側硬質部が回動する。そして、上記湾曲した複数の垂直羽根の翼面に沿って空気がスムーズに流れて、風向を水平方向に調整する。さらに、上記第１，第２連結部材の移動量を夫々調整して、複数の垂直羽根を自在にねじることによって、風向を上下方向に調整する。すなわち、上記第１，第２連結部材を例えば左方向に移動させる場合、上側の第１連結部材の移動量を下側の第２連結部材の移動量よりも大きくすると、各垂直羽根が反時計方向にねじれて、空気流に下向きの速度成分を与える一方、下側の第２連結部材の移動量を上側の第１連結部材の移動量よりも大きくすると、各垂直羽根が時計方向にねじれて、空気流に上向きの速度成分を与えるのである。なお、上記第１，第２連結部材を右方向に移動させる場合も同様である。したがって、上記第１，第２連結部材の移動量を夫々調整して、各垂直羽根のねじれ方向とそのねじれ量を調整することによって、水平羽根がなくとも、上下方向の速度成分を与えることができ、水平方向と上下方向の気流制御を行うことができる。
【０００８】
また、請求項２の空気調和機の吹出口構造は、請求項１の空気調和機の吹出口構造において、上記吹出口本体に、下流側に水平羽根を、上流側に上記複数の垂直羽根を配置したことを特徴としている。
【０００９】
上記請求項２の空気調和機の吹出口構造によれば、上記水平羽根の上下方向の傾動に応じて複数の垂直羽根をねじって、空気流に上下方向の速度成分を与えて、複数の垂直羽根からの空気流の水平羽根の翼面に対する傾きを小さくすることによって、水平羽根に沿って空気が流れやすくして、圧力損失を低減できる。また、上記複数の垂直羽根による水平方向の気流制御に対する水平羽根の影響が少なくなり、水平方向と上下方向の気流制御を効果的に行うことができる。
【００１０】
また、請求項３の空気調和機の吹出口構造は、請求項１または２に記載の空気調和機の吹出口構造において、上記複数の垂直羽根の並んでいる方向に上記第１連結部材を駆動する第１駆動手段と、上記複数の垂直羽根の並んでいる方向に上記第２連結部材を駆動する第２駆動手段とを備えたことを特徴としている。
【００１１】
上記請求項３の空気調和機の吹出口構造によれば、上記第１，第２駆動手段により第１，第２連結部材を別々に駆動して、第１，第２連結部材の各移動量を調整することによって、運転状態に応じて上記複数の垂直羽根を自動的にねじることができ、手動により第１，第２連結部材を調整する煩わしさがない。
【００１２】
また、請求項４の空気調和機の吹出口構造は、請求項１の空気調和機の吹出口構造において、上記吹出口に上記複数の垂直羽根の下流側に位置するように設けられた水平羽根と、上記複数の垂直羽根の並んでいる方向に上記第１連結部材を駆動する第１駆動手段と、上記複数の垂直羽根の並んでいる方向に上記第２連結部材を駆動する第２駆動手段と、上記水平羽根の上下方向の傾動に応じて、上記複数の垂直羽根がねじれるように上記第１駆動手段と上記第２駆動手段とを制御する制御手段とを備えたことを特徴としている。
【００１３】
上記請求項４の空気調和機の吹出口構造によれば、例えば、第１，第２連結部材を左方向に移動させたときに水平羽根が下向きの場合、制御手段により第１駆動手段と第２駆動手段とを制御して、上側の第１連結部材の移動量を下側の第２連結部材の移動量よりも大きくすることによって、各垂直羽根が反時計方向にねじれて、空気流に下向きの速度成分を与える。一方、上記第１，第２連結部材を左方向に移動させたときに水平羽根が上向きの場合、制御手段により第１駆動手段と第２駆動手段とを制御して、下側の第２連結部材の移動量を上側の第１連結部材の移動量よりも大きくすることによって、各垂直羽根が時計方向にねじれて、空気流に上向きの速度成分を与える。したがって、運転中に水平羽根の傾きが変化しても、水平羽根の上下方向の傾動に応じて複数の垂直羽根をねじり、空気流に上下方向の速度成分を与えて、複数の垂直羽根からの空気流の水平羽根の翼面に対する傾きを小さくするので、常に水平羽根に沿って空気が流れやくすして、圧力損失を低減できる。
【００１４】
【発明の実施の形態】
以下、この発明の空気調和機の吹出口構造を図示の実施の形態により詳細に説明する。
【００１５】
図１はこの発明の実施の一形態の空気調和機の吹出口構造の部分斜視図である。上記複数の垂直羽根１（図１では１つのみを示す）は、上流側硬質部１１と、下流側硬質部１２と、上記両硬質部１１，１２との中間の湾曲可能な軟質部１３で構成されている。そして、上記複数の垂直羽根１の上流側硬質部１１の上端を図示しない吹出口本体に固定している。また、上記複数の垂直羽根１の下流側硬質部１２の上端に第１連結部材２を回動自在に連結すると共に、複数の垂直羽根１の下流側硬質部１２の下端に第２連結部材３を回動自在に連結している。
【００１６】
また、図２に示すように、上記第１連結部材２の一端に伝動リンク４の一端を回動自在に接続し、その伝動リンク４の他端を略円筒形状の回転部（ステッピングモータを含む）６の下端面の外周近傍に回動自在に接続している。上記第１連結部材２の一端近傍には、長手方向に形成されたスリット２ａを有し、そのスリット２ａに図示しない吹出口本体に一端が固定されたガイド棒２１を嵌挿して、上記スリット２ａとガイド棒２１によって第１連結部材２を案内する。また、上記第２連結部３の一端に伝動リンク５の一端を回動自在に接続し、その伝動リンク５の他端を略円筒形状の回転部（ステッピングモータを含む）７の上端面の外周近傍に回動自在に接続している。上記第２連結部３の一端近傍には、長手方向に形成されたスリット３ａを有し、そのスリット３ａに図示しない吹出口に一端が固定されたガイド棒２２を嵌挿して、上記スリット３ａとガイド棒２２によって第２連結部材３を案内する。そして、上記回転部６，７の回転を制御する制御手段としてのコントローラ２０によって、上記回転部６，７を所定角度に回転させて、第１，第２連結部材２，３を伝動リンク４，５を介して長手方向に自在に移動させる。なお、上記伝動リンク４と回転部６で第１駆動手段を構成すると共に、伝動リンク５と回転部７で第２駆動手段を構成している。
【００１７】
上記構成の空気調和機の吹出口構造において、例えば、図３に示すように、上記回転部６，７（図２に示す）を回転させて、第１連結部材２を図中左の方向にｘ_Ｕ１移動させると共に、第２連結部材３を図中左方向にｘ_Ｌ１（＜ｘ_Ｕ１）移動させると、上流側硬質部１１をケーシングに固定しているので、第１，第２連結部材２，３に連動して、軟質部１３が湾曲しながら下流側硬質部１２が回動する。そして、上記複数の垂直羽根１が反時計方向にねじれて、空気流に下向きの速度成分を与える。なお、ｘ_Ｕ１，ｘ_Ｌ１は、垂直羽根１が湾曲していない位置からの第１，第２連結部材２，３の長手方向の移動量を示している。
【００１８】
一方、図４に示すように、上記回転部６，７（図２に示す）を回転させて、第１連結部材２を図中左の方向にｘ_Ｕ２移動させると共に、第２連結部材３を図中左方向にｘ_Ｌ２（＞ｘ_Ｕ２）移動させると、上流側硬質部１１をケーシングに固定しているので、第１，第２連結部材２，３に連動して、軟質部１３が湾曲しながら下流側硬質部１２が回動する。そして、上記複数の垂直羽根１が時計方向にねじれて、空気流に上向きの速度成分を与える。なお、ｘ_Ｕ２，ｘ_Ｌ２は、垂直羽根１が湾曲していない位置からの第１，第２連結部材２，３の長手方向の移動量を示している。
【００１９】
このように、上記第１，第２連結部材２，３の移動量を調整することによって、複数の垂直羽根１のねじれ方向とねじれ量を調整して、各垂直羽根１により水平方向と上下方向の気流制御を行うことができる。
【００２０】
また、上記吹出口本体に、複数の垂直羽根１の下流側に位置するように水平羽根１０（図３に示す）を設け、コントローラ２０により水平羽根用ステッピングモータ３０（図２に示す）を制御して、水平羽根１０を上下方向に傾動する場合、水平羽根１０の上下方向の傾動に応じて複数の垂直羽根１のねじり方向とねじり量を調整し、空気流に上下方向の速度成分を与えて、複数の垂直羽根１からの空気流の水平羽根１０の翼面に対する傾きを小さくすることによって、水平羽根１０に沿って空気が流れやすくして、圧力損失を低減できる。また、上記複数の垂直羽根１による水平方向の気流制御に対する水平羽根１０の影響が少なくなり、水平方向と上下方向の気流制御を効果的に行うことができる。さらに、上記複数の垂直羽根１と水平羽根１０の圧力損失を低減することによって、空気流に起因する騒音の発生を抑えると共に、送風ファンを低入力化できる。
【００２１】
また、上記第１駆動手段としての伝動リンク４と回転部６と、第２駆動手段としての伝動リンク５と回転部７とによって、第１，第２連結部材２，３を別々に駆動して、第１，第２連結部材２，３の各移動量を調整することによって、運転状態に応じて複数の垂直羽根１を自動的にねじることができ、手動により第１，第２連結部材２，３を調整する煩わしさがない。
【００２２】
また、上記水平羽根１０の上下方向の傾動に応じてコントローラ２０により回転部６，７を回転させ、上記第１，第２連結部材２，３を伝動リンク４，５を介して移動させて、複数の垂直羽根１をねじるので、運転中に水平羽根１０の傾きが変化しても、水平羽根１０の傾きに追随して、複数の垂直羽根１からの空気流に上下方向の速度成分を与えて、空気流の水平羽根１０の翼面に対する傾きを小さくでき、常に水平羽根１０に沿って空気が流れやすくして、圧力損失を低減することができる。
【００２３】
上記実施の形態では、第１駆動手段として伝動リンク４と回転部６と、第２駆動手段として伝動リンク５と回転部７とを用いたが、第１，第２駆動手段はこれに限らず、複数の垂直羽根の並んでいる方向に第１，第２連結部材を駆動するものであればよい。
【００２４】
【発明の効果】
以上より明らかなように、請求項１の発明の空気調和機の吹出口構造は、吹出口本体に固定された上流側硬質部と、下流側硬質部と、上記上流側硬質部と上記下流側硬質部との中間の湾曲可能な軟質部とからなる複数の垂直羽根を備え、上記複数の垂直羽根の下流側硬質部の上端に回動自在に連結した第１連結部材と、上記複数の垂直羽根の下流側硬質部の下端に回動自在に連結した第２連結部材とによって、複数の垂直羽根の上記軟質部をねじることができるようにしたので、第１，第２連結部材の移動量を夫々調整して、各垂直羽根のねじれ方向とそのねじれ量を調整することによって、水平羽根がなくとも、空気流に上下方向の速度成分を与えることができ、水平方向と上下方向の気流制御を行うことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air outlet structure of an air conditioner having a plurality of vertical blades at an outlet.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as an air outlet structure of an air conditioner, there is an air conditioner having a plurality of flat blades arranged in a horizontal direction at an air outlet. In the air outlet structure of the air conditioner, a plurality of vertical blades are rotatably connected to a connecting member, and each vertical blade is horizontally inclined to control the wind direction in the horizontal direction. However, in the above-mentioned flat vertical blade, as the inclination of the vertical blade in the horizontal direction increases, air does not flow smoothly along the vertical blade, the air flow downstream of the vertical blade is disturbed, and the pressure loss increases. There is a disadvantage that.
[0003]
Therefore, as shown in FIG. 5, an air conditioner including a vertical blade 50 including an upstream hard portion 51, a downstream hard portion 52, and a bendable soft portion 53 intermediate the hard portions 51, 52 is provided. An air outlet structure of a machine has been proposed (JP-A-4-13040). In the air outlet structure of this air conditioner, as shown in FIG. 6, a concave portion 54 provided at the upper end of a downstream hard portion 52 of a vertical blade 50 is rotatably fitted to a convex portion (not shown) of an upper air outlet main body 61. In addition, a convex portion 55 provided at the lower end of the downstream side hard portion 52 of the vertical blade 50 is rotatably fitted into a concave portion (not shown) of the lower outlet main body 62, and a plurality of vertical blades 50, 50,. 6 are shown in FIG. 6) at the outlet in the lateral direction. The fitting member 63 is fitted into a notch 51a shown in FIG. 5 provided at the lower end of the upstream hard portion 51 of the plurality of vertical blades 50, 50,. Are connected to each other. FIG. 7 is a top view of the vertical blades 50, 50,... And the connecting member 63 of FIG. 6 as viewed from above, and the vertical blades 50, 50,. Then, as shown in FIG. 8, by moving the connecting member 63 in the direction of arrow R, the soft portions 53 of the plurality of vertical blades 50, 50,. Adjust in the direction. In this manner, air flows smoothly along the curved vertical blades 50, 50,..., Pressure loss is reduced, and horizontal airflow control is performed.
[0004]
[Problems to be solved by the invention]
By the way, in the air outlet structure of the air conditioner including the plurality of bendable vertical blades 50, 50, the wind direction cannot be controlled vertically without the horizontal blades. When the horizontal blades are provided so as to be located downstream of the plurality of vertical blades 50, 50,..., The airflow control in the vertical direction by the downstream horizontal blades is dominant. There is a problem that the horizontal airflow control by 50,... Does not function sufficiently. Further, the horizontal blade tilts up and down, and as the inclination of the wing surface of the horizontal blade with respect to the airflow increases, the airflow bent in the horizontal direction by the vertical blade does not have a vertical velocity component in the horizontal blade. , There is a problem that the pressure loss due to the horizontal blades increases and the reach of the airflow is shortened.
[0005]
Therefore, an object of the present invention is to provide an air outlet structure of an air conditioner that can perform horizontal and vertical airflow control with reduced pressure loss and can increase the reach of an airflow.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, an air outlet structure of an air conditioner according to claim 1 includes an upstream hard portion fixed to an air outlet main body, a downstream hard portion, the upstream hard portion, and the downstream hard portion. A plurality of vertical blades comprising a bendable soft portion in between the first and second vertical blades; a first connecting member rotatably connected to an upper end of the downstream hard portion of the plurality of vertical blades; A second connecting member rotatably connected to the lower end of the downstream hard portion is provided, and the soft portions of the plurality of vertical blades can be twisted by the first connecting member and the second connecting member. It is characterized by doing so.
[0007]
According to the air outlet structure of the air conditioner of the first aspect, when the first and second connecting members are moved by the same amount in the same direction, the upstream hard portions of the plurality of vertical blades are fixed to the air outlet body. Therefore, the downstream hard portion rotates while the soft portion is curved in conjunction with the first and second connecting members. Then, air flows smoothly along the wing surfaces of the curved plurality of vertical blades, and the wind direction is adjusted in the horizontal direction. Further, the moving amount of each of the first and second connecting members is adjusted, and the vertical direction is adjusted by freely twisting the plurality of vertical blades. That is, when the first and second connecting members are moved, for example, to the left, if the moving amount of the upper first connecting member is larger than the moving amount of the lower second connecting member, each of the vertical blades is counterclockwise. If the amount of movement of the lower second connecting member is larger than the amount of movement of the upper first connecting member while each of the vertical blades is twisted in the direction to give a downward velocity component to the airflow, each vertical blade twists clockwise. , Giving the airflow an upward velocity component. The same applies to the case where the first and second connecting members are moved rightward. Therefore, by adjusting the amount of movement of the first and second connecting members, respectively, and adjusting the torsional direction and the amount of torsion of each vertical blade, it is possible to provide a vertical velocity component even without a horizontal blade. It is possible to perform horizontal and vertical airflow control.
[0008]
The air outlet structure for an air conditioner according to claim 2 is the air outlet structure for an air conditioner according to claim 1, wherein the air outlet body has horizontal blades on the downstream side and the plurality of vertical blades on the upstream side. It is characterized by being arranged.
[0009]
According to the air outlet structure of the air conditioner of the second aspect, a plurality of vertical blades are twisted in accordance with the vertical tilt of the horizontal blade to impart a vertical velocity component to the air flow, thereby providing a plurality of vertical blades. By reducing the inclination of the airflow from the blade to the blade surface of the horizontal blade, air can easily flow along the horizontal blade and pressure loss can be reduced. Further, the influence of the horizontal blades on the horizontal airflow control by the plurality of vertical blades is reduced, and the airflow control in the horizontal direction and the vertical direction can be effectively performed.
[0010]
In the air outlet structure for an air conditioner according to a third aspect, in the air outlet structure for an air conditioner according to the first or second aspect, the first connecting member is driven in a direction in which the plurality of vertical blades are arranged. And a second driving means for driving the second connecting member in a direction in which the plurality of vertical blades are arranged.
[0011]
According to the air outlet structure of the air conditioner of the third aspect, the first and second driving members are separately driven by the first and second driving means, respectively, and the respective movement amounts of the first and second connecting members. , The plurality of vertical blades can be automatically twisted according to the operation state, and there is no need to manually adjust the first and second connecting members.
[0012]
According to a fourth aspect of the present invention, in the air outlet structure of the air conditioner of the first aspect, the horizontal blade is provided at the outlet so as to be located downstream of the plurality of vertical blades. First driving means for driving the first connecting member in a direction in which the plurality of vertical blades are arranged; and second driving means for driving the second connecting member in a direction in which the plurality of vertical blades are arranged. And control means for controlling the first driving means and the second driving means such that the plurality of vertical blades are twisted in accordance with the vertical tilting of the horizontal blades.
[0013]
According to the air outlet structure of the air conditioner of the fourth aspect, for example, when the horizontal blades face downward when the first and second connecting members are moved leftward, the control means controls the first driving means and the first driving means. By controlling the second driving means to make the moving amount of the upper first connecting member larger than the moving amount of the lower second connecting member, each of the vertical blades is twisted in a counterclockwise direction to generate an air flow. Gives a downward velocity component. On the other hand, when the horizontal blades face upward when the first and second connection members are moved to the left, the control means controls the first drive means and the second drive means to control the lower second connection means. By making the amount of movement of the member greater than the amount of movement of the upper first connecting member, each vertical blade twists clockwise to impart an upward velocity component to the airflow. Therefore, even if the inclination of the horizontal blade changes during operation, the vertical blades are twisted in accordance with the vertical tilt of the horizontal blade, and a vertical velocity component is given to the airflow, so that the vertical Since the inclination of the airflow with respect to the blade surface of the horizontal blade is reduced, air flows and combs along the horizontal blade at all times, and pressure loss can be reduced.
[0014]

[0022]
In addition, the controller 20 rotates the rotating units 6 and 7 in accordance with the vertical tilt of the horizontal blade 10 to move the first and second connecting members 2 and 3 via the transmission links 4 and 5, Since the plurality of vertical blades 1 are twisted, even if the inclination of the horizontal blades 10 changes during operation, vertical velocity components are given to the airflow from the plurality of vertical blades 1 following the inclination of the horizontal blades 10. As a result, the inclination of the airflow with respect to the blade surface of the horizontal blade 10 can be reduced, so that air can always flow easily along the horizontal blade 10 and the pressure loss can be reduced.
[0023]
In the above-described embodiment, the transmission link 4 and the rotating unit 6 are used as the first driving unit, and the transmission link 5 and the rotating unit 7 are used as the second driving unit. However, the first and second driving units are not limited thereto.
