For maglev float magnet, so that magnetic suspension pot body can steadily be suspended in electricity while by electromagnetic oven heating
The top of the boiler face of magnetic furnace does not contact directly with the boiler face of electromagnetic oven, so as to avoid leaving difficulty on the boiler face of electromagnetic oven
With the trace of cleaning, solve the problems, such as that the boiler face of electromagnetic oven in the prior art is contaminated when heated, is difficult to clean.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the electromagnetic oven in the embodiment of the present invention.
Fig. 2 is the schematic top plan view of the magnetic suspended basement and electromagnetic heating coil in the embodiment of the present invention.
Fig. 3 is the schematic top plan view of the magnetic suspended basement in the embodiment of the present invention.
Specific embodiment
For technical solution of the present invention and advantage is more clearly understood, below in conjunction with drawings and the specific embodiments, to this
Invention is described in further detail.
Fig. 1 is the structural schematic diagram of the electromagnetic oven in the embodiment of the present invention, and Fig. 2 is the magnetic suspension bottom in the embodiment of the present invention
The schematic top plan view of seat and electromagnetic heating coil, Fig. 3 are the schematic top plan view of the magnetic suspended basement in the embodiment of the present invention.Such as figure
Shown in 1~Fig. 3, the electromagnetic oven in the embodiment of the present invention includes：Magnetic suspended basement 11, electromagnetic heating coil 12, magnetic suspension pot body
13；
Magnetic suspension permanent magnet 14 and magnetic suspension control electromagnet coil group 15 are provided in the magnetic suspended basement 11；
The upper surface of the magnetic suspended basement 11 is arranged in the electromagnetic heating coil 12；
It is provided in the magnetic suspension pot body 13 for maglev float magnet (not shown)；When the electromagnetic oven
When normal work, the magnetic suspension pot body 13 is suspended in the top of the electromagnetic heating coil 12.
According to the structure of above-mentioned electromagnetic oven it is found that electromagnetic heating coil can be used for when above-mentioned electromagnetic oven works normally
Magnetic suspension pot body is heated, realizes the heating function of electromagnetic oven；And magnetic suspension permanent magnet and magnetic suspension control in magnetic suspended basement
Electromagnet coil group processed can produce for maglev electromagnetic field, and the electromagnetic field and the float magnet in magnetic suspension pot body are mutual
Effect, the magnetic suspension pot body can be made to be suspended in the top of magnetic suspended basement so that the bottom of the magnetic suspension pot body not with electricity
The boiler face (electromagnetic heating coil i.e. on magnetic suspended basement) of magnetic furnace directly contacts, so as to avoid on the boiler face of electromagnetic oven
Leave the heating traces being difficult to clean.
In addition, preferably, in a specific embodiment of the present invention, the electromagnetic oven can further include：Magnetic suspension
Controller and electromagnetic heating controller；
The magnetic suspension controller can be set among the magnetic suspended basement or except, for controlling magnetic suspension control
Electromagnet coil group opens or closes；
The electromagnetic heating controller also can be set among the magnetic suspended basement or except, add for controlling electromagnetism
Size of current in heat coil.
In addition, in electromagnetic oven in the prior art, when electromagnetic oven is just opened, the heating function of the electromagnetic oven of default
Rate be it is most high-grade, different heating power shelves are then selected by controller again.Therefore, in electromagnetic oven in the prior art
When being just turned on, the curent change in electromagnetic heating coil will be rapidly increased to since 0 highest and add electromagnetic heating coil
Current value corresponding to thermal power shelves, so the current changing rate in this period will be very big, the current changing rate is to electricity
After the effect of magnetic heating coil, magnetic field caused by the electromagnetic heating coil will also increase rapidly from 0 to a biggish value, because
In the entire above process, the variation in magnetic field also will be very big for this.
The quick variation in above-mentioned magnetic field is likely to affect maglev magnetic field, destroys magnetic suspension condition.It is therefore advantageous to
, in one particular embodiment of the present invention, when the circuit of electromagnetic heating coil is just opened, the electromagnetic heating controller
It can also be used to control the electric current in the electromagnetic heating coil no more than preset current threshold.
Wherein, above-mentioned preset current threshold can be preset according to the needs of practical application, and the purpose is to make
The electromagnetic oven in rigid start to work, the operating power for heating of electromagnetic heating coil be a lower power (for example,
The heating power minimum less than or equal to the electromagnetic oven), so as to guarantee magnetcisuspension in the case where not destroying magnetic suspension magnetic field
The stable suspersion of floating pot body.When magnetic suspension pot body stable suspersion and then by electromagnetic heating controller has controlled the electromagnetism
The size of electric current in heating coil incrementally increases the heating power of the electromagnetic oven.At this point, due to the electricity in electromagnetic heating coil
Stream is to incrementally increase from a lesser value, therefore magnetic field caused by curent change is also to be stepped up, and will not destroy magnetic
The magnetic suspension state of suspension pot body.
In addition, preferably, in a specific embodiment of the present invention, the inductance of the electromagnetic heating coil is 500~800
Microhenry (μ H).
From the foregoing, it will be observed that the inductance of the electromagnetic heating coil in the present invention is far longer than electromagnetic oven commonly used in the prior art
Electromagnetic heating coil inductance (generally 200 μ H or so), therefore in normal work, the electromagnetic heating line in the present invention
Circle can be realized electromagnetic heating, and generated magnetic field is weaker while heating, does not interfere with maglev magnetic field, no
Magnetic suspension condition can be destroyed, so as to better ensure that the stable suspersion of magnetic suspension pot body.
In addition, preferably, in a specific embodiment of the present invention, the magnetic suspension pot body is arranged in the float magnet
Bottom.
In conclusion in the inventive solutions, due to being provided with magnetic suspension permanent magnet, magnetcisuspension in electromagnetic oven
Floating control electromagnet coil group and electromagnetic heating coil, and be provided in magnetic suspension pot body and be used for maglev float magnet,
So that magnetic suspension pot body can steadily be suspended in the top of the boiler face of electromagnetic oven while by electromagnetic oven heating, not with
The boiler face of electromagnetic oven directly contacts, and so as to avoid leaving the trace being difficult to clean on the boiler face of electromagnetic oven, solves existing
There is the boiler face of the electromagnetic oven in technology to be contaminated when heated, be difficult to the problem of cleaning.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the present invention.
