Abstract:
A high frequency heating apparatus equipped with an oven hood and provided at an upper portion of another heating cooking apparatus for cooking an object to be heated, the high frequency heating apparatus comprising:a main body of an appliance; a heating chamber for storing the object to be heated; heating means for cooking the object to be heated; cooling means for cooling the heating means; an air suction port for taking gas generated from another heat-cooking apparatus; ventilation means for exhausting air which is taken from the air suction port; an exhaust port for exhausting the air; a power converter having at least one semiconductor element, for converting electric power into high frequency power so as to supply the high frequency power to the heating means; and control means for controlling the semiconductor element, wherein the high frequency heating apparatus further comprises: initiation control means for controlling the control means in such a manner that when a heating operation is commenced, high frequency output power becomes higher than rated output power during the normal operation; and a time limiting element is provided with the initiation control means; wherein the initiation control means controls the control means in such a manner that the high frequency output power higher than the rated output power during the normal operation is outputted only for a time period determined by the time limiting element.
