Depending on the room temperature at that time, the frequency with which the fan blows can be automatically adjusted by controlling the swing.

In step S47, it is judged whether or not a predetermined time, 2 hours in this embodiment, has elapsed since the operation stop signal of the air conditioner 13 was received. If 2 hours have elapsed, the operation is stopped in step S48. Then, shift to the main routine. If two hours have not elapsed in step S47, it is determined in step S49 whether or not the signal from the air conditioner 13 has been received. When the environmental information signal from the air conditioner 13 is received, the process proceeds to step S39. , Step S39
Through step S49, the air conditioner 13 detects the room temperature and blows air at the same time, and operates by swinging according to the room temperature.

As another embodiment, as shown in FIG. 14, in step S46, if the room temperature of the environmental information signal from the air conditioner 13 is 28 degrees or more, the head swing motor in the set head swing mode is set. Rotate at high speed,
Further, if it is 28 degrees or less, the rotation speed of the swing motor in the set swing mode may be rotationally driven at a slower speed than that at 28 degrees.

That is, by performing such control, after the air conditioner 13 stops operating, so-called swinging is performed at a high speed when the room temperature is high, so that the frequency of the fan blows the user. You can get higher and get better comfort. Also, when the room temperature is low, the head swings at a slower speed than when the room temperature is high, so the frequency of the fan's wind hitting the user is low, and the frequency of the wind hitting the room can be changed by the swing speed. It is possible.
