Patent ID: 7087873

Claim:
A high-frequency heating apparatus with a steam generating function, which heat-treats an object by supplying at least high-frequency waves or steam to a heating chamber that accommodates said object, comprising: a high frequency wave generating portion; a steam generating portion for generating steam in said heating chamber, wherein said steam generating portion includes an evaporating dish that has a water storing recess adapted to generate steam by heating, and wherein said evaporating dish has tapered portions respectively provided at both end portions thereof so that said water storing recess gradually becomes shallower along a longitudinal direction thereof in each of said tapered portions; a circulating fan for agitating air in said heating chamber; wherein said steam generating portion has an evaporating dish heater for heating said evaporating dish; and an electromagnetic wave stirring portion for stirring high frequency waves sent from said high frequency wave generating portion and for supplying the high frequency waves to said evaporating dish.
