Abstract

PURPOSE:To perform uniform heating which is safe for a human body by a method wherein, when a body to be treated is provided and heated on a heating plate which is surrounded with a cover, an input/output port for the body to be treated is closed, and the inside of the cover is heated under a thermally exhausted state. CONSTITUTION:A body to be treated is provided and heated on a heating plate 19 which is surrounded with a cover 28. At this time, an input/output port 29 for the body to be treated is closed. At the same time, the inside of the cover 28 is heated under a heat exhaust condition. Therefore, inflow of outer air into the cover through the input/output port 29 can be prevented. Hot air in the cover 28 does not flow to the outside through the input/output port 29 since a heat exhaust pipe 37 is positively provided. Thus, the safe heating method characterized by the uniform distribution of heating temperature can be obtained.

Furthermore, as shown in FIG. 2, the partition plates A (34) B (35) have communication ports (38 )
may be provided, and the hot air above the shielding plates A (31) B (32) may be exhausted through this communication port (38).

It should be noted that it is better to arrange the shielding plates A (31) B (32) so that they do not come in contact with the entrance/exit A (29) and B (30) portions to avoid dust generation, and the shape is similar to that of the entrance/exit A (29).
It goes without saying that it is formed in accordance with the state in the vicinity of B (30).
