Abstract: A common annoyance for many people is the sensed change in temperature after disrobing or upon exiting the bathtub or shower stall area. The body heater/drier utilizes a unique means by which it disperses warm air to the many areas of the user. Air is drawn into the base assembly of the apparatus, heated and forced to flow into the tubing sections connected in series above. The air within increases in pressure since the total volumetric flow of air induced within the apparatus is greater than total volumetric flow of air which is possible through the limited total cumulative area of all the output openings. The resultant pressure causes the air to flow out of the apparatus in various directions and in varying volumes directly dependent upon the particular inclination in size and shape of each various output opening through which air flows. The output openings act jets to control air dispersal.
