Abstract
A closed type heating apparatus including a base plate to be placed on a floor or a bed, a space defining member having supports in the form of a pillar; a straight wall or a curved wall and an upper plate having a number of openings formed therein; and a heat conducting top plate placed on the upper plate. By combining different kinds of supports, there is formed a desired air passage within a closed space formed by the base plate and the upper plate. A heater unit including a ceramic heater and a blower is arranged in the air passage to generate a heated air stream such that the heating apparatus produces a desired temperature distribution.
