ABSTRACT:
The object of the present invention is to achieve a high frequency heating apparatus having a steam generating function that can implement simplification and miniaturization of the construction of a steam supply mechanism by omitting dedicated pump means for supplying water of a water tank.In a high frequency heating apparatus having a steam generating function (100), a steam supply mechanism (7) for supplying heating steam into a heating chamber (3) is constructed by a water tank (21) detachably equipped to the main body of the apparatus, water supply trays825), (25) mounted in the heating chamber (3), heating means (27), (27) for vaporizing water on the water supply trays (25), (25) by heating the water supply trays (25), (25), and water supply paths (29), (29) for leading water in the water tank (21) through heating areas based on the heating means (27), (27) to the water supply trays (25), (25), and the water in the water tank (21) is supplied to the water supply trays (25), (25) by using thermal expansion of water in the water supply paths (29), (29) which is caused by the heat generated in the heating means (27), (27).
