Abstract
Abstract A single casing houses first and second blowers for expelling air through first and second outlet passages. One of the outlet passages incorporates a heater so that hot air can be expelled. The other passage is free of any heater so that cool air is expelled from the second passage. By alternately actuating the blowers, a person can be treated to hot air and then cool air.
