Title:
MAGNETRON AND MICROWAVE HEATING DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2019/009173
Kind Code:
A1
Abstract:
A magnetron according to an embodiment comprises a magnetic circuit configured from a permanent magnet (13, 14) and a yoke configured by joining a first yoke (15) and a second yoke (16) together. The first yoke (15) and the second yoke (16) are joined together by means of plastic deformation of a joint portion (201) with which at least one of the first yoke (15) and the second yoke (16) is integrally provided. According to the present embodiment, the magnetron can be prevented from being used by a method outside the scope of warranty by the manufacturer, such as replacing a component with a non-genuine component. In this way, unstable operations can be suppressed and a decrease in lifetime can be prevented. Accordingly, it is possible to provide a highly reliable magnetron that cannot be disassembled without destruction of components.
