Is a power cord that is connected to.

As shown in FIGS. 3 and 4, the electric fan 10 is installed in a room 26 equipped with an air conditioner 25, and sends cool air to a user 28 or the like on a bed 27.

A room 26 in which the fan 10 is installed.
A case of performing the cooling operation will be described with reference to the flowchart of FIG.

When the operation unit 16 is pushed while the air conditioner 25 is in the cooling operation, the operation switch (not shown) of the fan 10 is closed (S1). When operating the operation unit 16, the set time of the timer (not shown) is set according to the timer operating time of the air conditioner 25 (S2). In this way, the operations of the air conditioner 25 and the fan 10 can be matched. Further, the fan and the temperature sensor may control the fan 10 according to time and temperature. As a result, the air conditioner 25 operates as the reverse rotation start type fan 10 during cooling (S3).
