き込み、その結果温度差によって上下風向変更羽根7に
結露7bが発生1−1その結露が滴下する現象を引き起
こしていた。Problems to be Solved by the Invention However, the bow-shaped vertical wind direction changing blade 7 has a large windless area 7a (hatched area) on the lower surface where the air does not pass, as shown in FIG. 6, during horizontal blowing. During cooling operation, air that has not been heat exchanged is drawn in from below as shown by arrow A, and as a result, condensation 7b is generated on the upper and lower wind direction changing blades 7 due to the temperature difference 1-1, causing the condensation to drip.
また、平板状の上下風向変更羽根7についても同様の現
象を引き起こしていた。Further, the same phenomenon occurred with respect to the flat plate-shaped vertical wind direction changing blade 7.
さらに、弓状、平板状の上下風向変更羽根7は、暖房運
転時の下吹出偏向角度が十分に達成できないという問題
があった。Further, the bow-shaped or flat-shaped vertical wind direction changing blade 7 has a problem in that a sufficient downward blow deflection angle cannot be achieved during heating operation.
そこで木発明は、上下風向変更羽根の下面において、風
の通らない無風の部分を大幅に減らし、冷房時の上下風
向変更羽根下面の結露を防止し、さらに、暖房時の下吹
風向角度が十分得られるようにするものである。Therefore, the invention of the tree greatly reduces the airless area on the lower surface of the vertical wind direction changing blade, prevents dew condensation on the lower surface of the vertical wind direction changing blade during cooling, and further increases the downward blow direction angle during heating. It is intended to be obtained.
問題点を解決するだめの手段
そして上記問題点を解決するための手段は、上面の一部
を弓状にわん曲し、下面をゆるやかな波形線の曲面にし
た上下風向変更羽根を回転可能なように吹出グリルの左
右両側壁に組み込んだものである。A means to solve the problem and a means to solve the above problem is to use a rotatable vertical wind direction changing blade whose upper surface is partially curved into an arch shape and whose lower surface is curved with a gentle wavy line. It is built into the left and right walls of the air outlet grill.
作 用 この技術的手段による作用は次のようになる。For production The effect of this technical means is as follows.
すなわち、上下風向変更羽根の水平時、下面に風を付着
させることにより、風の通らない無風の部分を大幅に減
らすことができ、また、下吹時には下吹出偏向角度が十
分に達成できるのである。In other words, by attaching the wind to the lower surface of the vertical wind direction change blade when it is horizontal, it is possible to significantly reduce the no-wind area where the wind does not pass, and also to achieve a sufficient downward blow deflection angle when blowing downward. .
実施例
以下、本発明の一実施例につき図面に基づいて説明する

、風下側曲面部(tlb)の中心は下面側に設定されて
いる。As shown in FIG. 1, the vertical wind direction changing blade 11 has an upper surface curved in an arch shape with the center of curvature on the lower surface side,
In addition, on the lower surface, there is a windward side curved surface part (11a) that is curved so as to gradually expand with respect to the wind flow, and a windward side curved surface part (lla) that is continuous with this windward side curved surface part (lla) and is curved so as to gradually expand with respect to the wind flow. A leeward side curved surface portion (11b) is provided which is curved so as to be round. The center of curvature of the windward curved surface portion is set on the upper surface side, and the center of the leeward curved surface portion (tlb) is set on the lower surface side.
この上下風向変更羽根11ば、従来と同様吹出グリルの
左右両端壁に回転可能に組み込まれている。The vertical wind direction changing blades 11 are rotatably incorporated in the left and right end walls of the outlet grille, as in the conventional case.
そして、本発明の効果を具体的に示すものとして、代表
的な風の流れを第2図の矢印で示す。As a concrete illustration of the effects of the present invention, typical wind flows are shown by arrows in FIG.
送風機(風上側)から送られてきた風は、上下風向変更
羽根11の下面に付着しやすいが、風上側曲面部11a
1風下側曲面部11bにより下面において無風の部分(
斜線部分)が大幅に減少する。The wind sent from the blower (windward side) tends to adhere to the lower surface of the vertical wind direction changing blade 11, but
1. Windless area (
(shaded area) is significantly reduced.
また、風下側曲面部11bの形状をゆるやかな弓状にな
るようわん画形成しているため、下吹出偏向角度も、飛
躍的て改善される。Further, since the shape of the leeward side curved surface portion 11b is formed into a gentle arch shape, the downward blow deflection angle is also dramatically improved.
なお、上下風向変更羽根11の上面は、平面状であって
もよい。Note that the upper surface of the vertical wind direction changing blade 11 may be flat.
