ELECTRIC FAN
Document Type and Number:
Japanese Patent JP2015209779
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric fan including a human sensitive sensor in which a detection sensitivity of oscillation range can be optionally set through arrangement of a sensitivity setting part for use in setting a sensitivity of the human sensitive sensor and the electric fan can be used without performing a re-setting operation on the basis of a sensitivity set by a user even after turning-on of a power supply by storing the detection sensitivity in a non-volatile memory.SOLUTION: An electric fan 100 including a human sensitive sensor of this invention comprises a human sensitive sensor part 7 having a plurality of human sensitive sensors 72a to 72e; a sensitivity setting part for setting detection sensitivities of the human sensitive sensors 72a to 72e; and a non-volatile memory 10d for storing detection sensitivities determined at the sensitivity setting part. When a power supply is turned on, a latest detection sensitivity is read out of the non-volatile memory and the operation is started again.
