本発明は、ファンモータの前方１；風圧Ｃ二て回転する
風向変更板を位置せしめた送風機に関し、前記風向変更

るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blower in which a wind direction changing plate is positioned in front of a fan motor and rotates at a wind pressure C2, and provides a blower that allows the wind direction changing plate to rotate smoothly and at a constant speed. It is something.
風圧鴫；で風向変更板を回転させる場合、風向変更板の
回転中心を中心とした対称部分Ｃ二、重量のアンバラン
スがあると、風向変更板にかかる風圧は常に一定なので
、回転速度Ｃ二むらが発生する。When rotating the wind direction changing plate with wind pressure, the rotational speed C2 is symmetrical about the rotation center of the wind direction changing plate.If there is an imbalance in weight, the wind pressure applied to the wind direction changing plate is always constant, so Unevenness occurs.
たとえば、風向変更板の他の部分に比較して重い部分が

向変更板は円滑に回転しない。そこで重量のバランスを
とるため（二、風向変更板の成型後、切削等（二よりバ
ランスを取ることも考えられるが、これでは作業能率が
低下してしまう。For example, when a part of the wind direction change plate that is heavier than other parts moves from the bottom to the top, a stronger downward force is applied to it than the gravity C, so the moving speed becomes slower. Also, when a heavy part moves from top to bottom, the gravity moves in the direction that makes it move faster, so the moving speed becomes faster. Therefore, the wind direction change plate does not rotate smoothly. Therefore, to balance the weight, (Secondly, after molding the wind direction changing plate, cutting, etc.) (Although it is possible to balance the process from the second point, this will reduce work efficiency.

Also, between the intermediate partition annular rib (to) and the outer circumferential annular rib (to), there is an inclined changing blade C which changes the direction of air blowing. j... are arranged in parallel f-, and the changing board... is in the diametrical direction of the atsushi board,
And it is connected by a reinforcing rib (to) f2 extending perpendicularly to the leg ridge. Also, the outer periphery and intermediate partition annular rib c! 61(C) is molded with the same width (L) and the same thickness tl l1 over the entire circumference i1. The modified wing...
The slope of ・is 1m from one wing (29a) to the other (29

ている。Therefore, the side having the modified wings (29b) with a larger inclination becomes heavier. Therefore, the weight balance of the wind direction changing plate is improved by making the reinforcing rib (total thickness t3) of the changing blade 0!11 thinner on the side where the slope of the changing blade (29) is smaller than that on the larger side. ! Il is in order. Furthermore, if the weight balance cannot be measured because the thickness adjustment of the reinforcing lip round is ≦2, the width ('L5) of the outer circumferential annular rib (to) should be adjusted to the side where the inclination of the changing wing is smaller (2) and the larger side to be smaller. It is set up.
