Problems solved by technology

[0002] In a microwave oven that uses microwaves to heat food, in order to make the food heated evenly, people use the tray (turntable) on which the food is placed to rotate for heating to control the uneven heating in the circumferential direction, but there will still be uneven heating, such as in the excitation port. If it is located on the side wall, some places in the heating chamber are heated evenly and strongly, such as around the tray, while some places are heated weakly, such as the middle of the turntable, resulting in waste of microwave energy and low heating efficiency. Usually, people only Desire to heat specific foods, hence the desire for targeted and efficient microwave heating

Embodiment Construction

[0021] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0022] "Metamaterial" refers to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. Through the orderly design of the structure on the key physical scale of the material, the limitation of some apparent natural laws can be broken through, so as to obtain the supernormal material function beyond the ordinary nature inherent in nature.

[0023] Three important features of "metamaterials":

[0024] (1) "Metamaterials" are usually composite materials with novel artificial structures;

[0025] (2) "Metamaterials" have extraordinary physical properties (often not available in natural materials);

[0026] (3) The properties of "metamaterials" are often not mainly...

Abstract

The invention discloses a microwave oven. The microwave oven comprises a cavity and a microwave generation mechanism, a meta-material is arranged in the microwave generation mechanism, the meta-material is composed of a base material and a plurality of artificial microstructures, the base material is divided in to a plurality of crystal lattices, the artificial microstructures are placed in the crystal lattices, the meta-material is divided into a plurality of sections along a horizontal direction, the central section has a largest product of a dielectric constant epsilon and a magnetic permeability mu, and the product of the dielectric constant epsilon and the magnetic permeability mu from the sections at two ends to the central section gradually increases. The microwave oven utilizes the meta-material to gather microwaves, so foods can be more pertinently heated, and the microwave heating efficiency is improved.

Description

technical field [0001] The invention relates to the field of microwaves, more specifically, to a microwave oven. Background technique [0002] In a microwave oven that uses microwaves to heat food, in order to make the food heated evenly, people use the tray (turntable) on which the food is placed to rotate for heating to control the uneven heating in the circumferential direction, but there will still be uneven heating, such as in the excitation port. If it is located on the side wall, some places in the heating chamber are heated evenly and strongly, such as around the tray, while some places are heated weakly, such as the middle of the turntable, resulting in waste of microwave energy and low heating efficiency. Usually, people only With the desire to heat specific foods, it is desirable that microwave heating be targeted and efficient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a microwave oven that hea...
