Abstract
A microwave heating apparatus (101) includes a burning chamber (103) in which an object (102) to be burned is placed, a magnetron (116) for applying microwaves into the heating apparatus, a cooling gas introducing mechanism (112b) for introducing a cooling gas from outside the heating apparatus into the heating apparatus, a cooling gas channel (113b) through which the cooling gas flows to the burning chamber (103), heat-generating members (114a to 114e) for self-heating with microwaves applied thereto to heat the cooling gas flowing through the cooling gas channel (113b) and a control section (117) for, when the burning chamber (103) having the object (102) to be burned placed therein is cooled, causing the cooling gas introducing mechanism (112b) to introduce the cooling gas into the heating apparatus, and causing the magnetron (116) to intermittently apply microwaves into the heating apparatus.
