Abstract
A microwave oven comprises a oven body with a cooking cavity and a bearing platform which is arranged in the cooking cavity and can contain food, wherein the bearing platform comprises a main body and a metal body, the main body is made of wave-transmitting materials, the metal body is positioned at the upper part or the lower part of the main body, and the edge of the metal body is smooth. The metal body is fixed with the main body through pasting or embedding, or the metal body is integrally formed with the main body through injection molding. The metal body is rectangular or circular, the metal body is in the shape of a sheet, and the minimum size of the length, the width or the diameter of the metal body is larger than 1/4 of the wavelength of the microwave. The metal sheet is provided with a plurality of rectangular holes. The length of the rectangular hole is integral multiple of the wavelength 1/4 of the microwave, and the width of the rectangular hole is less than or equal to 1/4 of the wavelength of the microwave. The metal body of the invention is a passive antenna, and utilizes the principle of a microwave passive antenna to pull, reflect and disturb microwaves in a cavity of the microwave oven, thereby achieving the purpose of improving the heating uniformity of the microwave oven. Under the condition that the existing rotary disc type microwave oven and the existing flat plate type microwave oven are not changed, the heating uniformity of the microwave oven is improved by more than 10 percent, and the microwave oven is simple in structure, low in manufacturing cost and suitable for popularization of enterprises.

Said metallic object is through pasting or inlaying with main body and fix, and perhaps metallic object is one-body molded through injection moulding and main body.
Said metallic object is rectangle or circle, metallic object in the form of sheets, the minimum dimension of its length and width or diameter is greater than 1/4 of microwave wavelength.
Said sheet metal is provided with several rectangular openings.
The length of said rectangular opening is the integral multiple of microwave wavelength 1/4, wide 1/4 of the microwave wavelength that is less than or equal to of rectangular opening.
Said main body is glass rotating disk, ceramic disk or the microcrystal glass plate that micro-wave oven is used, and its material is glass, pottery or other synthetic materials.
The present invention need not change the inner structure of micro-wave oven, as long as on main body (being glass rotating disk, ceramic disk or microcrystal glass plate), metallic object is set through on the basis of existing micro-wave oven, improving; And the metallic object edge is slick and sly, no corner angle; Can not cause spark phenomenon, metallic object is the passive type antenna, utilizes the passive antenna formula of microwave principle; Microwave in traction, reflection, the disturbance microwave oven cavity reaches the purpose that improves the micro-wave oven heating uniformity.Change under the little situation at existing rotating disc type micro-wave oven and flat plate microwave oven, promote its heating uniformity more than 10%, and it is simple in structure, cost of manufacture is low, be fit to the popularization of enterprise.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
First embodiment
Referring to Fig. 1; This micro-wave oven is the rotating disc type micro-wave oven, and it comprises the body of heater that has cooking cavity 14; But with the bearing table 11 that is arranged on food container 13 in the cooking cavity 14; Bearing table 11 is a rotating disk, and bearing table 11 rotates through driving shaft 12, and the waveguide assembly 15 and magnetron 16 that can be dissipated into microwave cooking cavity 14 also are set on this micro-wave oven.Bearing table 11 comprises main body and metallic object, and the edge of metallic object is slick and sly, no corner angle, and main body (being glass rotating disk, the ceramic disk that micro-wave oven is used) is made by electromagnetic wave transparent material, like pottery, glass or other synthetic materials etc., can supply microwave penetration.Open micro-wave oven, bearing table 11 rotates along with the driving of driving shaft 12, and the metallic object on it plays the effect of microwave antenna, can draw, the microwave in the reflection, disturbance microwave oven cooking chamber 14, reaches fast, the effect of heat food 13 equably.
Second embodiment
Referring to Fig. 2; This micro-wave oven is flat plate microwave oven, and it comprises the body of heater that has cooking cavity 26; But with the bearing table 21 that is arranged on food container 23 in the cooking cavity 26; Bearing table 21 is dull and stereotyped, and cooking cavity 26 corresponding bearing tables 21 are provided with rotating stirring piece 22, and the waveguide assembly 24 and magnetron 25 that can be dissipated into microwave cooking cavity 26 also are set on this micro-wave oven.Bearing table 21 comprises main body and metallic object, and main body (being microcrystal glass plate) is made by electromagnetic wave transparent material, like pottery, glass or other synthetic materials etc., can supply microwave penetration.Open micro-wave oven, stirring piece 22 rotate and to cooking cavity 26 in launched microwave, bearing table 21 maintenances are static, but are backward rotation with respect to stirring piece 22.Therefore, bearing table 21 can draw equally, the microwave in the reflection, disturbance microwave oven cooking chamber 26, under stirring piece 22 double actions, reaches fast, the effect of heat food 23 equably.
Referring to Fig. 3, Fig. 4; Be the front view of two kinds of difform bearing tables, two kinds of bearing tables include main body and metallic object; And the edge of metallic object is slick and sly, no corner angle, and wherein the shape of bearing table can be designed to different shapes according to the difference in microwave oven cooking chamber.As shown in Figure 3, circular bearing table 31 is suitable for the rotating disc type micro-wave oven.As shown in Figure 4, rectangle bearing table 32 is suitable for flat plate microwave oven.
