Description

本発明は、空気調和機における上下方向風向変更羽根の構造及び風向変更制御に関するものである。   The present invention relates to a structure of a vertical direction wind direction change blade and an air direction change control in an air conditioner.

従来、家庭用空気調和機の風向制御装置の構成は、図13(a)または図14(a)に示すように上下方向風向変更羽根8をディフューザー付近に回動自在に配設するタイプと図13(b)または図14(b)に示すように水受け皿付近に回動自在に配設するタイプに大別される。図13(a)、図14(b)は、それぞれのタイプにおける冷房時、図13(b)、図14(a)は、それぞれのタイプにおける暖房時の上下方向風向変更羽根の回動停止位置(例)を示している。また、下記特許文献1に記載されているように上下風向制御板の上羽根と下羽根を下方向に向けるとともに、前記上下風向制御板の上羽根を前記上下風向制御板の下羽根との平行位置より下方向に向け、前記上下風向制御板の下羽根を前記上下風向制御板の上羽根との平行位置より上方向に向けるようにした空気調和機(図15(a)〜(c))がある(例えば、特許文献1参照)。   2. Description of the Related Art Conventionally, the configuration of a wind direction control device for a domestic air conditioner is a type and figure in which an up / down direction wind direction change blade 8 is rotatably disposed near a diffuser as shown in FIG. 13 (a) or FIG. 14 (a). As shown in FIG. 13 (b) or FIG. 14 (b), it is roughly classified into a type that is rotatably disposed near the water tray. FIGS. 13 (a) and 14 (b) show the rotation stop position of the up / down direction wind direction change blades during cooling in each type, and FIGS. 13 (b) and 14 (a) show the up / down direction wind direction change blades during heating in each type. (Example) is shown. Further, as described in Patent Document 1 below, the upper blade and the lower blade of the vertical airflow direction control plate are directed downward, and the upper blade of the vertical airflow direction control plate is parallel to the lower blade of the vertical airflow direction control plate.

(For example, refer to Patent Document 1).

さらに、空気調和機の停止時には、吹き出し口を上下風向変更羽根で覆い塞ぐため、美観上、上下風向変更羽根は軽く弧を描く形状となっている。
特開平5−60365号公報
Furthermore, when the air conditioner is stopped, the air outlet is covered and covered with the up / down wind direction changing blades, so that the up / down air direction changing blades have a lightly arcuate shape.
Japanese Patent Laid-Open No. 5-60365

しかしながら、上記従来の構成である図13(a)では、冷房運転時には上下風向変更羽根及びその羽根形状に沿って冷風11は水平方向ないし、上向き方向に送風され、図4の17のように部屋の遠くまで冷風を運ぶことができる。これによって、人に直接冷風を当てることなく、気流感の少ない快適な環境が創れる。しかしながら、図14(a)の温風10のように暖房運転時には周囲の空気より温度の高く軽くなった気流10’が生成され、上下風向変更羽根から剥離していく。これにより、図5の温風19のように床面方面への到達性が悪化するという課題を有していた。   However, in FIG. 13A, which is the above-described conventional configuration, during the cooling operation, the cool air 11 is blown in the horizontal direction or the upward direction along the up / down air direction changing blades and the shape of the blades. Can carry cold air far away. As a result, it is possible to create a comfortable environment with less airflow without directing cold air on people. However, like the warm air 10 in FIG. 14A, during the heating operation, an air flow 10 'having a temperature higher and lighter than that of the surrounding air is generated and separated from the up and down airflow direction change blades. Thereby, it had the subject that reachability to a floor surface direction deteriorated like the warm air 19 of FIG.

また、図13(b)の構成では、暖房運転時には周囲の空気より温度の高く軽くなった温風10は上下風向変更羽根及び羽根形状により抑えられることにより、図5の温風20のように床面への到達性が良くなる。しかしながら、図14(b)のように周囲の空気より温度が低い場合は、周囲の空気よりも重く、上下方向風向変更羽根からの剥離される冷風11’が生成され、図4のように冷風18を部屋の遠方までを運ぶことができなくなり、室内の居住者に冷風が直接あたって肌寒さを感じさせるという課題を有していた。   Further, in the configuration of FIG. 13B, the warm air 10 that is lighter and warmer than the surrounding air during the heating operation is suppressed by the up / down wind direction changing blade and the blade shape, so that the warm air 20 in FIG. Reachability to the floor is improved. However, when the temperature is lower than that of the surrounding air as shown in FIG. 14B, the cold air 11 ′ that is heavier than the surrounding air and peeled off from the vertical wind direction changing blades is generated. As shown in FIG. As a result, it was impossible to carry the 18 to a distant place in the room, and there was a problem that the occupants felt indoors a chill.

上記特許文献1に記載されている空気調和機においては、温風を縮流効果により風速を増し、速やかに床面付近の温度を上昇させることはできるが、冷房時には、図14(b)と同様の課題を有していた。   In the air conditioner described in the above-mentioned Patent Document 1, it is possible to increase the wind speed by the effect of constricting warm air and quickly raise the temperature near the floor surface.
