Embodiment Construction

[0011] Such as figure 1 As shown, the preferred mode of realizing the present invention is: a kind of microwave oven casing material of the present invention is made of single-layer or multi-layer wire mesh and single-layer or multi-layer metal dielectric multilayer film of quantum well structure, wherein wire mesh such as figure 1 As shown in part 4, it consists of two sets of mutually perpendicular copper wires, the diameter of the copper wires is 0.05 mm, and the distance between any two adjacent parallel copper wires in each set of copper wires is 6 mm, the two sets of copper wires There is no direct conduction between the wires, and they are all cast in quartz glass. One side of the glass is compounded with a single-layer or multi-layer metal-dielectric multilayer film with a quantum well structure. At the same time, there is a 1 / 4 The structure of the wavelength path, such as figure 1 Shown in part 5, in another preferred embodiment of the present invention, the copper...

Abstract

A shell material of microwave oven is structured by single or multiphe layer of metal wire mesh and single or multiple layer of metal dielectric multilayer film in quantum well structure as each layer of metal wire mesh has been formed by metal thin wire flared-out in single set or multiple set and the metal wire mesh will be casted in transparent material of glass, organic glass, polyester or resin, or will be bound on transparent backing material by binding agent. A special design for the material is to make optical thickness between the metal wire mesh and the metal dielectric multilayer film near 1 / 4 times of operation wave length of the microwave oven so as to be able to use ITO film to replace metal dielectric multilayer film.

Description

Technical field: [0001] The present invention relates to a material for electromagnetic wave shielding, especially a material for shielding electromagnetic wave radiation of microwave ovens, in particular a shell material for microwave ovens composed of metal mesh and optical composite film with symmetrical structure of quantum wells . Background technique: [0002] In the prior art, the shell of the microwave oven adopts a metal plate. Since the metal plate is opaque, the metal plate on the front of the microwave oven adopts a mesh structure so that the user can observe the food inside. The operating frequency of microwave ovens is 2455 MHz, and the power is mostly between 700W and 1200W. A good quality magnetron produces microwave frequencies within the range of plus or minus 10 MHz around 2455 MHz. The national safety standard for microwave oven leakage is 5mw / cm 2 Within, the standard of many domestic manufacturers is 1mw / cm 2 within. Invention content: [0003] T...
