Abstract: A microwave treatment device according to one aspect of the present disclosure includes a heating chamber, a microwave generator, an amplifier, a feeder, a detector, a controller, and a storage. The microwave generator generates a microwave having an arbitrary frequency in a predetermined frequency band. The amplifier amplifies the microwave and outputs the amplified microwave as incident microwave power. The feeder supplies the incident microwave power to the heating chamber. The detector detects the incident microwave power and reflected microwave power that returns from the heating chamber to the feeder. The storage stores the incident microwave power and the reflected microwave power in association with the frequency of the microwave and time elapsed since the start of heating. The controller causes the microwave generator to execute a frequency sweep over the predetermined frequency band. The controller controls the microwave generator and the amplifier on the basis of the incident microwave power and the reflected microwave power detected during the frequency sweep.
According to the present aspect, the heating evenness can be improved.

Abstract: A heating cooking device includes a heater, a heating chamber, an imaging unit, a lighting unit, an image processor, and a lighting controller. The heating chamber accommodates an object to be heated. The imaging unit take images of the inside of the heating chamber. The lighting unit illuminates the inside of the heating chamber. The image processor analyzes an image to detect the brightness of the object to be heated in the image. The lighting controller controls the lighting unit in response to the brightness of the object to be heated. This aspect allows the heating cooking device to accurately determine a cooking state of the object to be heated on the basis of the image of the inside of the heating chamber taken to control the heater in response to the cooking state.

Abstract: This high-frequency treatment device includes: a heating chamber configured to accommodate a heating target; a high-frequency power generator; a feeder; a detector; a controller; and a storage. The high-frequency power generator generates high-frequency power having a frequency in a predetermined frequency band. The feeder supplies incident microwave power corresponding to the high-frequency power to the heating chamber. The detector detects at least one of the incident microwave power and reflected microwave power that is included in the incident microwave power and returns from the heating chamber to the feeder. The controller controls heating of the heating target by controlling the high-frequency power generator. The storage stores, together with time elapsed from the start of heating, information detected by the detector. The controller causes the high-frequency power generator to repeatedly generate, on a per frequency basis, the high-frequency power having a plurality of frequencies for the heating. The controller properly controls heating of the heating target on the basis of a temporal change in one of the reflected microwave power, a reflection ratio, and a microwave power difference.

Abstract: A microwave processing device of the present disclosure is provided with a heating chamber, a microwave generating unit, an amplifying unit, a power supply unit, a detecting unit, a control unit, and a storage unit. The microwave generating unit generates microwave having an optional frequency in a predetermined frequency band. The amplifying unit amplifies an output level of the microwave. The power supply unit radiates the microwave amplified by the amplifying unit into the heating chamber as incident electric power. The detecting unit detects reflected electric power, which returns to the power supply unit from the heating chamber, from among the incident electric power. The control unit controls the microwave generating unit and the amplifying unit. The storage unit stores a value of the reflected electric power, together with a frequency of the microwave and an elapsed time from the start of heating. The control unit controls the microwave generating unit and the amplifying unit based on a calculated value obtained by calculation with reference to the reflected electric power.

Abstract: The high-frequency treatment device according to one embodiment of the present disclosure includes: a heating chamber that accommodates a heating target; an oscillator; at least one feeder; a detector; and a controller. The oscillator generates high-frequency power having an arbitrary frequency in a predetermined frequency band. At least one feeder supplies incident microwave power based on the high-frequency power to the heating chamber. The detector detects the incident microwave power and reflected microwave power returning from the heating chamber to at least one feeder. The controller causes the oscillator to execute a frequency sweep and measures a reflection characteristic based on the incident microwave power and the reflected microwave power for each heating condition including a frequency. The controller determines, based on a reflection variation range indicating a change in the reflection characteristic for each heating condition, a heating condition to be used next. According to the present aspect, various heating targets can be optimally heated.
