Problems solved by technology

The microwave conversion of existing microwave ovens needs to be converted from the coaxial antenna or probe to the waveguide, so the more conversion times, the more microwave energy will be lost
At the same time, the cuboid waveguide cavity has the defects of high reflection power and low transmission efficiency

Abstract

The invention discloses a waveguide, an exciter with the waveguide and a microwave oven with the waveguide; the microwave oven comprises an oven body, a microwave source and the exciter, wherein a heating cavity is in the oven body; the exciter comprises the waveguide and a coaxial connector, wherein a waveguide cavity communicated with the heating cavity is in the waveguide; the first end of the waveguide cavity is closed; the second end of the waveguide cavity is opened; the cross section area of the waveguide cavity is increased from the first end to the second end; the first end and the second end are opposite; the coaxial connector comprises an outer conductor and an inner conductor positioned at the inner side of the outer conductor; the inner conductor passes through the outer surface of the waveguide and stretches into the waveguide cavity; the coaxial connector is connected with the microwave source. The microwave oven provided by the embodiment of the invention has the advantages of being good in heating effect, high in heating efficiency and the like.

Description

technical field [0001] The present invention relates to a waveguide, and also relates to an exciter and a microwave oven with the waveguide. Background technique [0002] A microwave oven is a common appliance used for heating or cooking. The microwave oven includes a microwave source, a cavity, an oven door and other parts. Among them, the microwave source is the core component of microwave generation, and the microwave generated by the microwave source needs an exciter to transmit the microwave to the cavity to realize food heating. [0003] An antenna or a probe of an exciter of a conventional microwave oven is inserted into a cuboid waveguide cavity. Especially in semiconductor microwave ovens, the output of the semiconductor microwave source is a coaxial output. The microwave conversion of the existing microwave oven needs to be converted from the coaxial antenna or probe to the waveguide, so the more conversion times, the more microwave energy loss will be. At the s...
