- 摘要：
PROBLEM TO BE SOLVED: To provide an air diffuser in which the power consumption of a fan motor of an electric fan is reduced without lessening a diffusion effect of the air diffuser so much, so that the operation of the electric fan can be continued even when a battery is not exchanged over a long period of time.
SOLUTION: The fan motor for rotating the fan is rotated intermittently, namely, is rotated for a rotation period and stopped for a standstill period by turns. An operation mode of a motor driving circuit is controlled so that the rotation period has a high-speed rotation period just after the start of the rotation of the fan motor and a low-speed rotation period subsequent to the high-speed rotation period.
