Description
Technical field
The present invention relates to household electrical appliance technical fields, and in particular to a kind of micro-wave oven reducing microwave leakage.
Background technology
The principle of microwave heating is always to contain a certain amount of moisture, and water in food when on microwave radiation to food
It is made of polar molecule, the orientation of this polar molecule is changed with the variation of microwave field.Due to the polarity of water in food
Interaction between this movement of molecule and adjacent molecule, produce makes water temperature increase similar to the phenomenon that friction, therefore, food
The temperature of product also just rises.With the food of microwave heating, because also being heated simultaneously inside it, whole object is made to be heated evenly,
Heating rate is also fast.
Various electronic products, during use, all can or strong or weak generation electromagnetic radiation.Domestic microwave
Stove is 2440 megahertzs of microwave radiation, is one kind in electromagnetic radiation.China's regulation household micro-wave oven or industrial microwave add
The microwave leakage amount of hot equipment is:At equipment 5cm, power≤5mW/cm2 of 2440MHz microwaves, 915MHz microwaves
Power≤1mW/cm2.It can be said that household microwave oven is the equipment that can generate most strong microwave radiation in family.Although household is micro-
The wall of wave stove has good shielding action, but since household microwave oven can not be absolutely sealed, mistake of the micro-wave oven in heating food
Cheng Zhong, inside will produce steam, and the effect of micro-wave oven gas vent is discharge steam, balances external and internal pressure.Existing air hole
Structure can still cause the excessive leakage of a small amount of microwave.When the dosage of microwave radiation is more than that a certain degree, or accumulative dosage is super
After crossing to a certain degree, it is possible to cause different degrees of influence to physical condition.Household electrical appliance have stringent electromagnetic radiation mark
Standard only considers harm of the single electric appliance to user, electric appliance is more and more, and the time gets over when formulating standard per the same electric appliance
It more grows, accumulative amount of radiation is ceaselessly increasing.Reduce the health for reducing the electromagnetic radiation of every electric appliance beneficial to user.Household is micro-
When wave furnaceman makees, user can be actively teaches away from the microwave radiation that household microwave oven avoids household microwave oven;Child may not
The prompt of parent is accepted, close to household microwave oven;After the elderly may start household microwave oven, forget far from household microwave oven
;Also household microwave oven, not enough spaces is used to avoid microwave radiation in narrow space.
Production firm and researcher constantly studied the technology for the microwave radiation for reducing micro-wave oven.Multifunctional household microwave
The radiation protective layer that stove radiation shield CN101329081A has studied reduces electromagnetic radiation dosage of the household microwave oven to user;One kind can
Negative magnetic-inductive capacity material electromagnetic screen CN101208004A for household microwave oven and processor, which has studied, utilizes negative magnetic conductance
The forbidden band effect of rate material inhibits electromagnetic radiation leakage;A kind of electromagnetic bandgap structure and a kind of shielding household microwave oven electromagnetic radiation
Fire door frame panel CN103517624A have studied based on electromagnetic bandgap structure inhibition household microwave oven electromagnetic radiation face
Plate;Anti- microwave from leakage household microwave oven CN106352379A, which has studied in the cavity that stove seat and micro-wave screening cover surround, heats food
Microwave absorbing layer can be absorbed and be decayed to microwave, and the probability of microwave from leakage is reduced;A kind of transparent electricity of household microwave oven
Magnetic wave screened film CN201383886Y has studied the one side setting metal conducting layer in transparent support, for solving domestic microwave
Stove electromagnetic radiation;Household microwave oven has studied electro-magnetic screen layer with electromagnetic shielding cutting means enclosure CN202267101U and setting exists
The waterproof layer and fireprotection layer of electro-magnetic screen layer both sides.
Invention content
The purpose of the present invention is:Between the venthole and fire door and furnace body of the observation window, micro-wave oven that are arranged on fire door
Gap reduces there are the microwave radiation leakage of different degree or avoids the microwave radiation of household microwave oven to the injury of user,
Especially children, old man and the user that micro-wave oven is used for a long time in small space for a long time.
Technical solution is used by the present invention solves prior art problem:The metallic reflection plate of trepanning is provided with multiple small
The food heated is observed in hole convenient for user;The aperture of the metallic reflection plate of trepanning is much smaller than microwave wavelength, avoids microwave diffraction
Leakage;The most of microwave of metallic reflection plate reflection of trepanning returns in microwave oven body, and a small amount of microwave of leakage is by interior transparent
Plate absorbs the microwave of leakage to stove external radiation, transparent electrolyte aqueous solution, and finally, the outer transparent panel of few microwave penetration is let out
Leakage;Transparent electrolyte aqueous solution is injected from water injection hole, and the liquid level of transparent electrolyte aqueous solution is higher than the height of interior transparent panel,
It is equipped with cavity in door for microwave oven body, the air after transparent electrolyte aqueous solution expanded by heating in compaction cavum avoids transparent
Electrolyte aqueous solution leaks;Interior transparent panel is identical with the size of outer transparent panel.
Liner and shell constitute microwave cabinet;Small steel ball after the preferred magnetization of microwave absorption pearl, surface coats iron content oxygen
The Microwave Absorption Coating of body powder;The inner materials of microwave absorption pearl can also be that ceramics or glass, surface coating contain ferrite powder
Microwave Absorption Coating;Interior air hole and outer air hole are staggered, and interior air hole and outer air hole face is avoided to be arranged.From interior
The microwave of air hole leakage gradually weakens by the reflection and absorption of microwave absorption pearl, and the air of expanded by heating is through interior air hole
It is overflowed from outer air hole, keeps the pressure balance inside and outside micro-wave oven.
When user is close to the household microwave oven to work, the heat of the normally closed type human body infrared inductive switch of micro-wave oven
Release electric transducer and detect user's infrared radiation signal, according to the intensity of signal judge user with work in micro-wave oven away from
From user is less than the safety identification distance of setting at a distance from the micro-wave oven in work, and voice prompt user keeps at a distance, avoids
The microwave radiation leakage of household microwave oven.User is less than the shutdown distance of setting at a distance from the micro-wave oven in work, and household is micro-
Wave stove, which is shut down, to be waited for, and after user is more than the safety identification distance of setting at a distance from the micro-wave oven in work, is again started up micro-
Wave stove completes scheduled work, avoids the microwave radiation leakage of household microwave oven to the injury of user.Safety identification distance is more than
Shut down distance.
With the above structure, microwave absorption pearl reduces the microwave radiation leakage of household microwave oven air hole to the present invention, thoroughly
Bright electrolyte aqueous solution absorbs the microwave radiation leakage of domestic microwave fire door observation window, and normally closed type human body infrared inductive switch carries
The user that wakes up avoids the microwave radiation leakage of household microwave oven, and pause household microwave oven avoids wound of the microwave radiation leakage to user
Evil.
