Title:
マグネトロンとこれを備えたマイクロ波加熱装置
Document Type and Number:
Japanese Patent JP7008185
Kind Code:
B2
Abstract:
A magnetron according to an aspect of the present disclosure comprises a magnetic circuit that includes permanent magnets and a yoke. The yoke includes a first yoke and a second yoke that are joined together. The first yoke and the second yoke of the magnetron according to this aspect are joined together by plastic deformation of a joint part provided integrally with at least one of the first yoke or the second yoke. This aspect can prevent the magnetron from being used in a manner that is not guaranteed by a manufacturer, such as using a non-genuine replacement for a component. Thus unstable operation can be suppressed, and a shortened life can be prevented. The magnetron that can be provided consequently cannot be disassembled unless the components are destroyed and thus is highly reliable.
