であるので圧力損失の変化は極めて小さい。The diffusion switching blade 7 is connected to the ventilation hole 1 of the lower cylinder 102.
When it comes to the end opposite to the initial state of 01, the rotation direction of the diffusion switching plate driving motor 9 is switched to rotate the diffusion switching blade 7 so as to return the position of the diffusion switching blade 7 to the initial state. Even if the rotation direction of the diffusion switching blade 7 is opposite, if the diffusion switching blade 7 and the ventilation hole 101 have the same overlap, the same diffusion characteristic of the blown air flow can be obtained, and the sum of the center angles of the opening portions of the ventilation hole 101 is always 2α. , That is, since the opening area is always constant, the change in pressure loss is extremely small.
