Abstract
The utility model relates to a household electric appliance casing with an electromagnetic shielding function, which takes a plastic casing body as a basal body. Electromagnetic interference preventing material is arranged in the plastic casing body or is covered on the surface of the plastic casing body to form the compound structure of a plastic layer and an electromagnetic interference material layer. The electromagnetic interference preventing material can use conducting mesh grids, metal films, metal foils, conducting paint and conducting rubber films. The casing with the compound structure not only can effectively enhance the electromagnetic interference preventing capability of household electric appliances and ensure the household electric appliances to have stable operation, clear figures and angles and normal sound, but also can have simple technology and convenient manufacture. The utility model can be widely used for the household electric appliances such as television sets, CVD, DVD, etc.
Description
The utility model belongs to the casing of household electrical appliance, particularly a kind of household electrical appliance casing with electro-magnetic screen function.
Existing household electrical appliance casing is generally cabinet, this kind casing almost is " transparent " to electromagnetic wave, the function that does not promptly have anti-electromagnetic interference, thereby influenced the stability of household appliances, for example can make the television image disorder under Electromagnetic Interference, sound accompaniment distortion, noise increase etc. is exactly an illustration.Along with development of electronic technology, electromagnetic interference will be more and more serious.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of household electrical appliance casing with electro-magnetic screen function is provided, to guarantee the serviceability of household electrical appliance.
The purpose of this utility model is achieved in that according to the characteristics of electromagnetic wave propagation and the mechanism of electromagnetic shielding the household electrical appliance casing that unitary plastic is made improves, and makes it to become the casing of composite bed structure, thereby has the function of anti-electromagnetic interference.Under the guidance of above-mentioned design philosophy, the household electrical appliance casing that the utility model provides is matrix with the plastic casing and is provided with in plastic casing or the surface is topped that anti-electromagnetic interference material arranged at it, to form the composite bed structure.Anti-electromagnetic interference material can adopt conductive mesh grid, metal film, metal forming, electrically-conducting paint and conductive rubber film.If metallic mesh can be arranged in the plastic casing, form sandwich-type casing by plastic wraps conductive mesh grid; Also can be the topped inner surface of metallic mesh at plastic casing.If metal film, electrically-conducting paint, conductive rubber film, then topped inner surface or outer surface at plastic casing; If metal forming, then topped inner surface at plastic casing.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a kind of structural map of household electrical appliance casing provided by the utility model, and anti-electromagnetic interference material is a metallic mesh;
Fig. 2 is the structure chart of metallic mesh;
Fig. 3 is second kind of structural map according to household electrical appliance casing provided by the utility model, and anti-electromagnetic interference material is a metal film;
Fig. 4 is the third structural map according to household electrical appliance casing provided by the utility model, and anti-electromagnetic interference material is an electrically-conducting paint;
Fig. 5 is the 4th a kind of structural map according to household electrical appliance casing provided by the utility model, and anti-electromagnetic interference material is a metal forming.

Embodiment 4:
Household electrical appliance casing in the present embodiment is the DVD player shell, and it is constructed as shown in Figure 5.Anti-electromagnetic interference material 2 be an aluminium foil, sticks on the inner surface of plastic casing 1, the compound structure of formation plastic layer and aluminium foil layer with epoxy resin.
Structure of the present utility model is not limited to the foregoing description, for example the conductive mesh grid can also be made by tungsten filament, metal film can also be the aluminium film, electrically-conducting paint can also be that nickel is coating (being made by solvent acetone and nickel powder, film-forming resin butyl acrylate, coupling agent titanate esters), and anti-electromagnetic interference material can also be selected the conductive rubber film for use.
The utlity model has following advantage:
1. can effectively improve the anti-electromagnetic interference capability of household electrical appliance, make its working stability, clear picture, sound is just Often.
2. technology is simple, is convenient to make, and is easy to promote.
3. compare with existing cabinet, the increasing degree of cost is little, but the overall price/performance ratio of household electrical appliance significantly improves.
The utility model can be widely used in household electrical appliance such as television set, CVD, DVD.
