Description
Technical field
The present invention relates to micro-wave ovens.In particular it relates to a kind of micro-wave oven for being evenly heated material using higher mode high efficiency.
Background technique
Microwave energy is substituted for various traditional heating modes.Micro-wave oven utilizes the various foods of Microwave Heating and material
Material, in microwave chemical field, microwave energy be used to accelerate various chemical reactions.Microwave energy is also used for nano material, artificial
The production of a variety of materials such as diamond.
During traditional heating, heat is by conducting inside it, belonging to surface heating, causing outside heating object
Heating object internal and external temperature is uneven.In Microwave Heating, microwave is material-to-be-heated by electric field action, leads to wherein polarity point
The damping vibration of son generates heat, belongs to body heating.Therefore it is heated simultaneously inside and outside heating object.
But there is the whole homogeneity question of heating in conventional microwave oven.
In any confined space of heating chamber etc, electromagnetic wave by because covibration with the various intrinsic of the cavity
The form of mode of resonance exists.In wherein any one mode of resonance, electromagnetic wave all exists with standing wave form, leads to space
The amplitude of the electric field of a little fixed positions is maximum, and in addition the amplitude of certain fixed positions is zero.It is micro- in the typical case of 2450MHz
Wave energy applying frequency, these electric fields concentrate between distance be operational microwave used wavelength half or slightly larger, substantially exist
Between 61 ~ 100 millimeters, cause material-to-be-heated uneven on corresponding scale.
The size of common household microwave oven is 5 ~ 10 times bigger than above-mentioned scale.It can near the working frequency in these cavitys
With the mode of resonance number that motivates for several to dozens of.There's a widespread conviction that by people, is conducive to using the heating chamber that height spends mould
The uniformity of microwave heating.But any superposition of plurality of mode of resonance may be generated in certain positions of heating chamber
Electric field much larger than other positions is concentrated, and causes the extreme of microwave heating uneven.
In order to solve the homogeneity question of Microwave Heating, international and domestic technical staff has carried out unremitting effort.
It is attempted to the feedback mouth number by increasing operational microwave, changes feedback mouth-shaped, changes the feedback mouth of operational microwave outside heating chamber
The position on surface perhaps changes the polarization direction of the feedback mouth of operational microwave or changes above-mentioned several variables at random simultaneously, passes through
It calculates or the method for improving heating uniformity is found in actual measurement.But up to the present, in micro-wave oven, especially large size micro-wave oven
The homogeneity question of heating is not well solved.
Let us understands we face in micro-wave oven heating uniformity technical problem.In the frequency of operational microwave
Rate, for a certain microwave present mouth, after selecting its position, shape, polarization direction, in heating chamber several to dozens of modes respectively by
The determination of the intensity of excitation be all computationally it is very difficult, it is in actual measurement and extremely complex.And large-scale microwave
It is needed in furnace using multiple magnetrons as microwave source, therefore the number of corresponding microwave feedback mouth is also multiple, microwave stove heating
The complexity of problem exceeds the imagination of people.
Summary of the invention
The present invention passes through the operating mode controlled in mould heating chamber, provides a kind of micro-wave oven of homogeneous heating.
To achieve the goals above, the technical solution adopted by the present invention are as follows:

Multirow radiator, in heating chamber microwave distribution more effectively controlled, improve the uniformity of heating.
Can also include multiple row radiator in X direction: at least one described radiating curtain includes at least two column along X-axis
Radiator.The radiating curtain passes through floor to the heating chamber microwave radiation energy.
In order to allow microwave field the communication process being distributed in heating chamber in remain unchanged as far as possible, any radiating curtain
On radiator be all uniformly distributed in X direction and along Z-direction.Meanwhile the spoke in all radiators on same radiating curtain
The microwave penetrated is coherent wave.Belong to the microwave of all radiators radiation of same a line along X-axis arrangement on same radiating curtain
Amplitude it is identical and phase is identical.Along the two of the arbitrary neighborhood for belonging to same row of Z axis arrangement on same radiating curtain
The amplitude of the microwave of a radiator radiation is identical, and phase is also identical.
Further, we allow each radiator to be located at same by the mode and field distribution of microwave in each radiator of control
Belong to center line along Z axis one side of the microwave in each radiator of the radiator radiation of same a line on radiating curtain along X-axis arrangement
On electric field component in the Z-axis direction be zero.
The alternatively paster antenna of radiator.The antenna mainly includes being supported by dielectric material plate positioned at Jie
On the sheet metal radiator of material plate surface and another side opposite with the sheet metal radiator on the dielectric material plate
Microwave excitation structure.At this moment, the spacing between the paster antenna center adjacent and along X-axis jingle bell along Z axis is all work
6/5 ~ 9/5 times for making the wavelength of microwave free space.Preferably design, paster antenna here are square.
Another kind design, any radiator are coaxial antenna.Here the coaxial antenna is presented using coaxial line
Enter microwave energy.Medium between the outer conductor and outer conductor and inner conductor of the coaxial line is cut off, but its inner conductor stretches out
Into free space.In order to improve radiation effect, the height of radiator is reduced, we are connected to a gold on the top of inner conductor
Belong to disk or square conductor thin slice.The characteristics of this coaxial antenna is in certain two vertical direction of its coaxial line, electromagnetism
Field is all mirror symmetry.It is described along X-axis is adjacent and spacing between the adjacent coaxial antenna center of Z axis be operational microwave from
By 6/5 ~ 9/5 times of the wavelength in space.Belong to the micro- of the radiator radiation of same row along Z axis arrangement on same radiating curtain
