えた高周波加熱装置。A high-frequency oscillator such as a magnetron that supplies high-frequency waves to the heating chamber, and heaters are provided above and below the heating chamber, and one heater is connected in series with a rectifying element and a control rectifying element connected in parallel. A switch is provided to short-circuit and open both ends of the control element, and from the sum of the power consumption when the switch of the heater connected in series with the control element is opened and the power consumption of other heaters, the control element is connected in series. The power consumption when the switch of the connected heater is short-circuited is less or the same, and the power consumption when the switch of the heater connected in series with the control element is opened is greater than the power consumption of other heaters. The configuration is such that the current flowing through the control element is controlled, and a control rectifier element and a rectifier element are connected in parallel with the forward directions of current flowing in opposite directions, and are connected in series with one of the heaters. , an electric skylight having a structure in which a switch that short-circuits and opens both ends of the rectifying element and the control rectifying element is a double-throw contact, and when the rectifying element is short-circuited, the heater on the side to which the rectifying element is not connected is disconnected. High frequency heating device equipped with.
