Patent ID: 7326893

Claim:
A high frequency heating apparatus having a steam generating function, comprising: a heating chamber containing a heated object; high frequency wave generating means for outputting a high frequency wave into the heating chamber; and a steam supply mechanism for supplying heated steam into the heating chamber; wherein the heated object is heated to process by supplying at least either of the high frequency wave and the heated steam to the heating chamber; wherein the steam supply mechanism comprises: a water storing tank mounted attachably and detachably to and from an apparatus main body; an evaporating portion mounted to inside of the heating chamber; heating means for evaporating water by heating the evaporating portion; a transport tube for transporting water to the evaporating portion by making water in the water storing tank boil locally by an energy generated by the heating means; and a heat conduction control portion comprising a material having a heat conductivity smaller than a heat conductivity of a material forming the evaporating portion and interposed between the transport tube and the heating means; and wherein an amount of a heat energy conducted from the heating means to the heat transport portion is controlled.
