Abstract: A microwave treatment device comprises 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. The controller also 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. In this aspect, it is possible to accurately recognizes the progress of cooking while heating the object. Accordingly, cooking can be finished appropriately.

Abstract: Microwave oven (20) includes waveguide (3) having an E-bend structure, and multiple openings (4a, 4b). Waveguide (3) has first section (3a) for propagating a microwave from magnetron (2) toward heating chamber (1), and second section (3b) of which wide plane abuts on the outer wall of heating chamber (1). Multiple openings (4a, 4b) are disposed on a lateral face of heating chamber (1). Openings (4a, 4b) allow waveguide (3) to communicate with heating chamber (1), and include at least one circularly-polarized-wave opening (4a) for generating a circularly polarized wave. A cross section of first section (3a) orthogonally intersecting tube axis (7a) of first section (3a) is projected virtually along tube axis (7a) of first section (3a) onto a lateral face of heating chamber (1), and circularly-polarized-wave opening (4a) is formed such that its center is located outside the resultant projected region defined by this projection. The foregoing structure allows this compact size waveguide to generate a circularly polarized wave more positively.

Abstract: A microwave treatment device comprises: a heating chamber that accommodates an object to be heated; a microwave generator that generates a microwave in a specified frequency band; an amplifier that amplifies the microwave; a feeding unit that supplies the amplified microwave to the heating chamber; a detector that detects a reflected microwave power; and a controller. The controller selects one of plural frequencies in the specified frequency band and causes the microwave generator to generate the microwave with the selected frequency. The controller causes the amplifier to change an output power of the microwave so that the microwave supplied to the heating chamber has one of plural output powers. The controller measures a reflected microwave frequency characteristic based on reflected microwave powers detected under each of a condition that the microwave has a first output power and a condition that the microwave has a second output power.

Abstract: A high-frequency heating apparatus according to an embodiment of the present disclosure includes a heating chamber, an electrode, a high-frequency power supply, at least one matching element, and a controller. The heating chamber accommodates a heating target. The high-frequency power supply applies a high-frequency voltage to the electrode. The impedance matcher includes at least one matching element having a matching constant that is variable. The controller stops the high-frequency power supply to complete heating based on a temporal change of the matching constant of the at least one matching element. In this embodiment, a heating target can be heated efficiently.

Abstract: The present invention has a configuration of controlling motor (15) so as to stop radiation antenna (5) when radiation antenna (5) faces in a direction in which a reflected wave detection amount is minimized and to stop radiation antenna (5) when radiation antenna (5) faces in a different direction different from the direction in which the reflected wave detection amount is minimized. According to this configuration, first, radiation antenna (5) stops when facing in the direction in which the reflected wave detection amount is minimized. This extends a heating time under the most efficient condition, improving a heating efficiency in comparison with when radiation antenna (5) constantly rotates. Second, radiation antenna (5) stops when facing in the different directions. This causes uneven heating when radiation antenna (5) faces in the direction in which the reflected wave detection amount is minimized as well as when radiation antenna (5) faces in the different directions. As a result, the uneven heating is cancelled out by the uneven heating each other caused at different locations. In this way, it is possible to achieve the even heating.

Abstract: A microwave treatment device comprises: a heating chamber that accommodates a heating target, a microwave generator that generates a microwave; a feeding unit that supplies the microwave to the heating chamber; a reflected microwave power detector that detects a reflected microwave power returned to the microwave generator; a controller that controls the microwave generator; and a storage unit. The storage unit stores a level of the reflected microwave power detected by the reflected microwave power detector together with a frequency of the microwave supplied to the heating chamber and an elapsed time after a start of heating the heating target. The controller causes the microwave generator to execute a frequency sweep over a specified frequency band and determines that the heating target is in a boiling state based on a temporal change in a value that is obtained based on the reflected microwave power at each frequency.
