Abstract

A split-type microwave oven comprises a first housing assembly, a second housing assembly, a microwave source module, a microwave shielding and choking member, and a detection device that is used for detecting whether a wave leakage occurs in a microwave heating resonant cavity. The second housing assembly is detachably disposed on the first housing assembly. The first housing assembly is provided with a first microwave shielding member, the second housing assembly is provided with a second microwave shielding member, and the first microwave shielding member is suitable for defining, together with the second microwave shielding member, the microwave heating resonant cavity. The microwave source module is installed on one of the first housing assembly and the second housing assembly. The microwave shielding and choking member is located outside the microwave heating resonant cavity. The split-type microwave oven occupies a small space and is convenient to use.
