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、回転速度にむらが発生する。(b) Conventional technology When rotating a wind direction changing plate due to wind pressure, if there is an unbalance of weight in the symmetrical part of the wind direction changing plate around the rotation center, the wind pressure applied to the wind direction changing plate is always constant. Uneven rotational speed occurs.
たとえば、風向変更板の他の部分に比較して重
い部分が下から上に移動する場合、重力により下
向の力がより強くかかるため、移動速度が遅くな

転しない。そこで重量のバランスをとるために、
風向変更板の成型後、切削等によりバランスを取

してしまう。 For example, when a portion of the wind direction changing plate that is heavier than other portions moves from the bottom to the top, a stronger downward force is applied due to gravity, which slows down the movement speed. Also, if the heavy part moves from top to bottom,
Conversely, gravity acts in the direction that moves faster, so the speed of movement becomes faster. Therefore, the wind direction changing plate does not rotate smoothly. In order to balance the weight,
After molding the wind direction changing plate, it may be possible to balance it by cutting or the like, but this would reduce work efficiency.

A motor 3 is screwed into a motor mounting recess 7 formed in the center of the housing 2 via a motor support plate 8 in which a motor fitting hole is formed. Further, a storage case 11 containing a switch 10 and the like is fixed in a notch 9 formed on the upper surface of the housing 2. Legs 12, 12 for stably supporting the casing are formed on the lower surface of the casing 2, and the legs 12 are long in the front and back so as to protrude from the casing 2. The front frame 6 is fixed to the upper inner surface of the frame by engaging a pair of locking tongues 13 formed on the lower surface of the frame into engagement holes 14 formed on the upper surface of the front end of the leg portion. The locking portion 15 is engaged with an engaging protrusion 16 integrally formed on the front side of the storage case, and is removably attached to the housing.

回転すると共に風向変更板５の強度も向上する。 A mounting boss portion 25 is formed in the center of the wind direction changing plate 5 to be attached to the rotating shaft 22 by a spinner 23. Rectifying blades 27 extending in the direction are formed. Further, between the intermediate partition annular rib 26 and the outer peripheral annular rib 28, inclined changing blades 29 for changing the direction of air blowing are formed in parallel, and the changing blades 29 have a diameter of the changing plate. The blades 29 are connected by reinforcing ribs 30 extending in the direction and perpendicular to the blades 29. Further, the outer periphery and intermediate partitioning annular ribs 26, 28 are molded to have the same width (L) and the same thickness (t) over the entire periphery. In order to efficiently change the wind direction by the changing blades 29, the changing blades 29 are formed such that the slope increases from one blade 29a to the other blade 28b. The changing blade 29 has a constant width (L 1 ) when measured in the same direction as the width of the wind direction changing plate 5. Therefore, the side having the modified wings 29b with a larger inclination becomes heavier. Therefore, the weight balance of the wind direction changing plate 5 is adjusted by making the thickness (t 3 ) of the reinforcing rib 30 of the changing blade 29 thinner on the side where the slope of the changing blade 29 is smaller than on the side where the slope is larger. .
By adjusting the thickness (t 3 ) of the reinforcing ribs 30, which does not significantly affect the wind direction change, the weight is balanced, the wind direction change plate 5 rotates smoothly and at a constant speed, and the strength of the wind direction change plate 5 is increased. It also improves.
