It is decided that an air-conditioner is brought into a stop as a result of the environment temperature being increased to a given temperature. When it is detected that current illumination is below given illumination, it is decided that a user is under a sleep, and an electric motor 42 is run.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fan for improving comfort during sleep.

[0002]

2. Description of the Related Art An air conditioner is used to eliminate sleepiness, but a timer operation is generally performed to prevent coldness. However, the room temperature may rise again after the operation of the air conditioner is stopped, and sleep may be disturbed.

In order to solve the problem, a fan configured to operate when the room temperature exceeds a predetermined temperature after the air conditioner has been stopped was proposed in Japanese Utility Model Publication No. Sho 63-63594 (F04D 27/00). . With this configuration, the timer of the fan must be set in accordance with the timer setting of the air conditioner, and there is a drawback in that it is not convenient to use. Also, since the air conditioner operates intermittently or inverts to maintain the room temperature at the set temperature, the room temperature changes within a range of several degrees. It is configured to operate when the room temperature at the time of measuring the reference temperature happens to be high because the room temperature is measured before the time is set to the reference temperature and the difference between the reference temperature and the room temperature after the air conditioner is stopped reaches a predetermined temperature. However, there is a drawback that the fan does not operate even when the temperature reaches the user's desired temperature, which gives the user discomfort.

Further, during sleep, stopping the operation of the air conditioner is very uncomfortable for the user, and causes sleepiness.
