Abstract
A high-frequency heating apparatus with a steam generating function, which heat-treats a to-be-heated object by supplying at least high-frequency waves or steam to a heating chamber 11 that accommodates the object. This high-frequency heating apparatus has a high frequency wave generating portion 13, a steam generating portion 15 for generating steam in the heating chamber 11, and a circulating fan 17 for agitating air in the heating chamber 11. Moreover, the high-frequency heating apparatus has a chamber air heater 19 for heating air circulating in the heating chamber 11. The steam generating portion 15 generates steam by heating an evaporating dish 35 that has a water storing recess.
Claims25
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.
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, provided in said heating chamber, for generating steam from an evaporating dish that has a water storing recess adapted to generate steam by being heated,
- 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,
- 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.
