Abstract: A microwave treatment device includes a heating chamber for accommodating a heating target, a microwave generator, a feeder, a detector, and a controller. The microwave generator generates a microwave having a frequency in a specified frequency band. The feeder radiates the microwave inside the heating chamber. The detector detects a reflected microwave power reflected from the heating chamber. The controller causes the microwave generator to execute a frequency sweeping in the specified frequency band, and controls the microwave generator according to a temporal change in a frequency characteristic of the reflected microwave power. The temporal change in the frequency characteristic of the reflected microwave power is based on the frequency of the microwave, a level of the reflected microwave power, and a time passed from a start of heating. Thus, it is possible to accurately recognize the progress of cooking while heating the object.

Abstract: A high-frequency heating apparatus includes: a heating chamber for accommodating a load; a microwave source; at least one radiator; a temperature detector; and a controller. The microwave source generates a microwave and adjusts the frequency and output of the microwave. The at least one radiator radiates a microwave into the heating chamber. The temperature detector detects the temperature in the heating chamber. The controller causes the microwave source to adjust the output of the microwave based on the temperature profile that defines the temperature change in the load, and the temperature in the heating chamber. According to this aspect, food can be heated in accordance with the temperature profile appropriate for the cooking recipe, thereby ensuring the quality of cooked food.

Abstract: A high frequency heating apparatus (1A) includes the following components: a first electrode (11) that is flat; a plurality of flat second electrodes (12) that are flat; a high-frequency power supply (20); a matching unit (30); a controller (40); and an electric field regulator (50). The second electrodes (12) are placed opposite to the first electrode (11). The high-frequency power supply (20) applies a high-frequency voltage to the first electrode (11). The matching unit (30) is placed between the first electrode (11) and the high-frequency power supply (20), and is impedance-matched with the high-frequency power supply (20). The controller (40) controls the high-frequency power supply (20). The electric field regulator (50) individually adjusts the electric field strengths in a plurality of regions located between first electrode (11) and the second electrodes (12). This aspect can reduce uneven heating.
