Title:
MICROWAVE TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/020374
Kind Code:
A1
Abstract:
This microwave processing device comprises a heating chamber (1) that accommodates an object (2) to be heated, a microwave generation unit (3) for generating microwaves, a power supply unit (5) for supplying microwaves to the heating chamber (1), a detection unit (6) for detecting reflected electrical power directed towards the microwave generation unit (3), a control unit (7) for controlling the microwave generation unit (3), and a memory unit (8). The memory unit (8) stores the amount of reflected electrical power detected by the detection unit (6), together with the frequency of microwaves supplied to the heating chamber (1) and the time elapsed since the start of heating. The control unit (7) controls the microwave generation unit (3) so as to carry out a frequency sweep across a prescribed frequency band, and determines that the object (2) to be heated is in a boiling state on the basis of the change, over time, of a value based on the reflected electrical power at each frequency. According to the present disclosure, it is possible to accurately sense the boiling state of the object to be heated and perform cooking in a suitable manner.
