Another object of the present invention is to control the light source and the heating element, which are means for activating the catalyst, so that the effect of the catalyst is sufficiently exhibited.

It is a further object of the present invention to provide an air conditioner with a deodorizing function that takes into consideration running costs, repair costs, and maintainability.

[0016]
