In FIG. 1, reference numeral 31 is an external power source such as a commercial power source, a generator or a battery, which supplies power to the high frequency heating device 32 from the outside through the switching section 40.
The high frequency heating device 32 is a power conversion unit 3 that converts this power.
3 and a radio wave radiating section 34 which receives the electric power converted by the power converting section 33 to generate a high frequency electric wave (for example, a microwave) and supplies the high frequency electric wave to a heating chamber (not shown). The power converter 33 is, for example, the power converter 3
5 and the converter control unit 36. Further, the high-frequency heating device includes a storage battery 37, the output of which is either a power converter 33 via a booster 38 and a switch 40 or a heater 39 which supplies heat energy to the heating chamber during oven heating. It is a configuration that is supplied to one side.
The storage battery 37 may have an output voltage of 45 V or less. At this time, since the storage battery 37 has a low voltage, there is no risk of electric shock or electric contact. Therefore, it can be installed at any place, and it may be built in the housing of the high-frequency heating device or attached to the outside. The heating control unit 41 controls the converted power of the power conversion unit 33, for example, by controlling the converter control unit 36, and adjusts the magnitude of the output radio wave of the radio wave emission unit 34. Further, the heating control unit 41 supplies electric power to the heater unit via the booster unit 38 to the storage battery 37 when the electric power conversion unit 33 is supplied with electric power from the external power supply 31 during simultaneous high frequency heating and oven heating. When the power is supplied from the storage battery 37 to the power conversion unit 33 via the booster 38, the switching unit 40 is controlled so that the power to the heater 39 is supplied from the external power supply 31. Thus, heating by high frequency radio waves and heating by an oven can be controlled.

As described above, when the high frequency radio wave and the heater are simultaneously heated, the power supply source of the heater unit 39 and the power supply source of the power conversion unit 33 are independent, so that the heater does not interfere with each other. It can be set to an arbitrary value such that the section 39 can be maximized and the high frequency output can be maximized. Further, in the case of cooking in which the heater is used for a long time, the electric power is supplied to the heater unit 39 from the external power source 31, and conversely, in the case of cooking in which the heater is used for a short time, the storage battery 37 and the booster unit 38 are used. Controlling the switching unit 40 to supply electric power to the heater unit 39 has an advantage that the storage battery can be used for a long period of time.

As described above, since cooking can be performed at high output without being limited by the input current capacity from the external power source, it is possible to attach a brown mark to the container and it takes too much time to cook food. It is possible to prevent the taste from being deteriorated by being dried too much.

Since the power supplied from the external power supply is supplied to either the power conversion unit or the heater unit and the output power of the storage battery is supplied to the other, the current capacity of the external power supply is limited. The microwave heating and the oven heating can be simultaneously performed without any need, and the cooking speed can be increased, and further, the finished condition of the cooking can be improved.
