Embodiment Construction

[0026] The application will be described in further detail below in conjunction with the accompanying drawings and embodiments. In particular, the following examples are only used to illustrate the present application, but not to limit the scope of the present application. Likewise, the following embodiments are only some of the embodiments of the present application but not all of them, and all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0027] In order to suppress the RE of the microwave oven, those skilled in the art usually add a magnetic ring to the microwave oven, and shield the RE through the magnetic ring to reduce leakage. However, the material cost and production cost of the magnetic ring are relatively high; and the shielding effect of the magnetic ring on RE is not obvious, and it cannot suppress electromagnetic waves in the full frequency band; at the same time, due ...

Abstract

The present application discloses a microwave oven. The microwave oven includes a frequency converter, a magnetron, a first wire and a second wire. The power supply end of the frequency converter is connected to the power supply end of the magnetron through the first wire, and the ground end of the frequency converter is connected to the magnetron through the second wire. The ground terminal is connected, wherein the first wire and part of the second wire are arranged in parallel, and the distance between the first wire and part of the second wire is less than a preset distance. In this way, the RE of the microwave oven can be reduced, and the microwave oven can be made to comply with the EMC standard.

Description

technical field [0001] The present application relates to the technical field of electrical appliances, in particular to a microwave oven. Background technique [0002] Electromagnetic compatibility (EMC) of electrical products is a very important quality index. It not only relates to the working reliability and safety of electrical products, but also affects the normal operation of other equipment and systems. Therefore, microwave ovens must pass the EMC standard before they can be listed. [0003] The inventors of the present application have discovered in the long-term research and development process that microwave ovens currently on the market are mainly divided into industrial frequency microwave ovens and variable frequency microwave ovens. Power frequency microwave ovens use power frequency transformers to boost the voltage, while variable frequency microwave ovens use frequency conversion technology to convert commercial power into high voltage at high frequencies....
