Abstract

The invention relates to the field of same-frequency circuits, and discloses a multi-source signal generating device and a microwave oven. The multi-source signal generating device comprises a first local frequency source, a first microwave signal generating device, a second local frequency source and a second microwave signal generating device, wherein the first local frequency source is used for providing a first reference frequency signal; the first microwave signal generating device corresponds to the first local frequency source, and is used for generating and outputting a first output frequency signal according to the first reference frequency signal; the second local frequency source is used for providing a second reference frequency signal; the second microwave signal generating device corresponds to the second local frequency source, and is used for generating and outputting a second output frequency signal according to the second reference frequency signal; and under the condition that the second microwave signal generating device receives the first output frequency signal generated by the first microwave signal generating device, the second microwave signal generating device generates a corresponding output frequency signal according to the first output frequency signal to serve as the second output frequency signal to be output. Through adoption of the scheme, absolutely the same frequency signals can be transmitted by different signal sources, and phase control can be performed.

Description

technical field [0001] The invention relates to the field of co-frequency circuits, and in particular, to a multi-source signal generating device and a microwave oven including the multi-source signal generating device. Background technique [0002] A microwave oven is a cooking appliance that uses food to absorb microwave energy in a microwave field to heat itself. The microwave generated by the microwave generator in the microwave oven establishes a microwave electric field in the microwave oven cavity, and certain measures are taken to make this microwave electric field distribute as evenly as possible in the oven cavity, and the food is put into the microwave electric field, and the cooking time is controlled by the control center and microwave electric field strength for various cooking processes. [0003] The microwave generator in the existing microwave oven mostly uses a crystal oscillator as the frequency reference of the microwave generator, and the reference freq...
