Description

Low door for microwave oven, the chamber structure of leaking

Technical field:

The utility model relates to household electrical appliance.More particularly, be a kind of microwave oven, dishwasher, disinfection cabinet class electrical appliance.

Background technology:

Progress along with society, household electrical appliance are day by day popularized, the fail safe of electrical equipment is paid much attention to by various countries scientific research institution, factory, user for a long time, the household electrical appliances " three C authentication " that China implements recently are exactly the up-to-date compulsory standard that ensures user security, and purpose is to ensure user's personal safety and safety of property.Because the purposes difference of electrical work, the transform mode difference of electric energy is bigger, has that electricity refrigeration, electricity heat, an electricity system wind, electricity system light, electricity system electromagnetic wave etc.; With the microwave oven is example, be electricity system microwave energy, because the particularity of microwave energy, add that existing microwave oven is again to place in kitchen and human body proximity, near work, thus new microwave oven or use through the regular period after door, the sealing in storehouse, the microwave energy leak detection when microwave oven is worked of old microwave oven be one of technical indicator of paying close attention to most of management organization, manufacturing enterprise, user.

Existing door for microwave oven, the storehouse faying face is the direct combination of biplane, by designing requirement, should be to fit like a glove when closing, use the gap after certain time limit natural aging should be less than microwave wavelength, otherwise by door, the microwave of storehouse slot leakage has very big infringement to user health, in fact, the traditional microwave fire door, the faying face in storehouse is because the rising-heat contracting-cold and the wear of hinge of door body material, reasons such as external impacts, be difficult to accomplish to combine closely for a long time, even new microwave oven, since the fine difference of production technology and assembly program, door, the junction, storehouse also is that certain slit is arranged, and microwave energy is by slot leakage when causing microwave oven work.Because the self-characteristic of microwave energy, even leakage is arranged, the user also is difficult in time discover, and user's harm is had suitable disguise; And for the microwave oven user, repeatedly use microwave oven every day possibly, so microwave leakage to user's infringement with service time length relevant, suitable continuation is arranged.

Thereby improve microwave oven fail safe, reduce the especially old microwave oven of microwave oven because door, gap, storehouse increase the microwave energy that leaks when making its work and increase, it is just extremely important to prevent that it from damaging user health.

Summary of the invention:

Problem to be solved in the utility model provides a kind of method that improves microwave oven safety, makes new, the door of old microwave oven, junction, storehouse more can prevent the leakage of microwave energy, so that bring higher degree of safety to the user.

The technical scheme that the utility model is dealt with problems is:

The low microwave oven choke that leaks is set in the inboard of the external frame of door for microwave oven, concrete structure is that the plane with choke four limits strikes out on-plane surface, the obtuse angle shape that links to each other to several M shapes as concavo-convex staggered waveform or etc., with its be complementary type corresponding be low leakage microwave cavity panel on the microwave oven main body, this panel also strikes out concavo-convex staggered waveform or to the continuous obtuse angle shape of several M shapes, when closing door, during the storehouse, the convex-concave position of the corresponding inner chamber panel in concavo-convex position on the choke, its faying face becomes concavo-convex staggered face, both complementations by traditional plane.The microwave that produces during microwave oven work is by door, storehouse faying face the time, the trend that microwave leaks becomes many faceted pebble refractions, scattering by traditional near the minute surface refraction, the refraction number of times increases, refraction path prolongs, every refraction once, the microwave energy decay once reduces the purpose that microwave energy leaks thereby reach; Even if the microwave oven work several years, door, faying face gap, storehouse increase, and the trend that the microwave that produces during microwave oven work leaks remains between the faying face of bending, are forced to repeatedly reflect, scattering, and its leaking energy reduces, thereby more can guarantee user's safety.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

The utility model strikes out on-plane surface by the plane with choke four limits and microwave cavity panel, the obtuse angle shape that links to each other to several M shapes as concavo-convex staggered waveform or, when closing door, storehouse, the concavo-convex position on the choke and the convex-concave position complementation of inner chamber panel, its faying face becomes concavo-convex staggered on-plane surface face by traditional plane; The microwave that microwave oven when work produces is forced to repeatedly reflect, scattering by door, storehouse faying face the time, and the microwave leakage energy is attenuated, and more guarantees user's safety, guarantees user health.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.
