  • Patent number: 10743378
    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.

  • Patent number: 10588182
    Abstract: A semiconductor microwave oven and a semiconductor microwave source thereof. The semiconductor microwave oven includes: a body, a microwave input device, a semiconductor microwave source and a control device. The semiconductor microwave source includes a signal source, a power divider and N drive amplifiers. The signal source is configured to generate a first microwave signal. Power of the first microwave signal is allocated by the power divider to generate N second microwave signals. Each drive amplifier is configured to conduct drive amplification on the second microwave signal, and respectively to input same to the microwave input device to transmit into the chamber. The control device is configured to control the signal source to generate the first microwave signal. The microwave oven shares one signal source to guarantee operating at the same frequency, thereby realizing the highly efficient power output.
