In order to achieve the above object, an air conditioner with a scent generator of the present invention comprises a blower for blowing temperature-controlled air, a scent generator and a scent concentration controller. And a control means for controlling to operate the blower when either the cooling and heating system or the scent generating means is driven, and the cooling and heating system. A blowout angle control means is provided for adjusting the blowout angle so that the temperature-controlled air is blown out horizontally or upward when the system is turned off.

[0010]

With the above structure, even when the room temperature reaches the set temperature and the cooling and heating system is turned off during the cooling or heating operation, the scent is continuously supplied by the blower while the scent is being supplied from the scent generating means. The scent does not stay inside, and you can continue to add fragrance to the room. Further, for example, when heating and when the heating system is turned off, the air is blown horizontally or upward, so that the scent can be continuously supplied without causing the user to feel a cold sensation (cold draft) due to the airflow. ..

As a result, a fragrance can be added to the room at any time as required, and a living environment can be formed that has a psychologically and physiologically favorable effect.
