Adjustment.
Reformed AHP is done at many aspects in order to improve efficiency in the present embodiment, wherein more it is important that in pot
The transducing coil 408 for collecting energy is provided on frame 4, the cardinal principle of transducing coil 408 is the electromagnetic energy that will be collected into
Electric energy is converted to, 3 main function of resonance coil in the present embodiment is to be worked by electromagnetic energy to provide electromagnetic heater
Energy, transducing coil 408 are arranged on magnetic core 1, and the electromagnetic energy that resonance coil 3 generates necessarily is conducted by magnetic core, in other words,
Electromagnetic energy is inevitable also by transducing coil 408, and transducing coil 408 goes out the electrical energy transportation of generation, is delivered to and is arranged in pot frame 4
Controller 5 on, the work of device 5 in order to control provides electric energy, on the one hand the controller 5 in the present embodiment connects transducing coil 408
Energy is obtained, on the other hand, controller 5 also fans 407, inspection pot sensor 405 and temperature sensor with the even windburn on pot frame 4
406 are connected, and then the accurate manipulation of each section is realized by controller 5.The electromagnetic heaters such as traditional electromagnetic oven exist
One larger problem will necessarily have certain radiation due to being electromagnetic heating, although amount of radiation is little, people exist
It can usually be absorbed in thought attitude when purchase, worry that the health of itself can be done by large effect, the present embodiment for the problem
It improves, on the outside of the upper edge of the first pot frame 401, is provided with that a circle is conductive or the shirt rim 6 of magnetic conduction, can be inhaled by shirt rim 6
Leakage field between getter gap can achieve the purpose that zero radiation substantially, in addition, the material selected have it is certain be particular about, it is conductive or
The material of magnetic conduction can not only absorb the leakage field of air gap, moreover it is possible to the waste heat that the bottom of a pan rises are trapped in cookware edge, be further reduced
The waste of the energy is sealed in electronic circuit this part, the present invention using insulation, waterproof material, it is preferred that selects epoxy
Resin carries out sealing.
Embodiment two
The present embodiment as shown in Figure 3, with embodiment one the difference is that the position of resonance coil 3 in one end of magnetic core and
It is not in centre, in this way, vacate more spaces goes out different firepower distributions convenient for multigroup coil combination.
Embodiment three
For opposite embodiment one and embodiment two, resonance coil 3 and 1 arrangement mode of magnetic core in the present embodiment are done
In larger change, embodiment one and embodiment two be that resonance coil is wrapped in above magnetic core, and the magnetic core 1 in embodiment three be by
A plurality of small magnetic core composition, radial arrangement are substantially in the drum magnetic core of round pie, and center is hollow, and edge is in
The heart raises up so that the magnetic core 1 of round pie forms a circular groove, and drum magnetic core is close to the bottom surface of panel.Therefore,
Resonance coil in embodiment three one encloses arrangement from inside to outside along the circle shape groove of the magnetic core 1 of round pie, and is laid with
Resonance coil 3 the number of plies or density gradually increase from inside to outside, ultimately form it is outer thickness in it is thin, compared with the first two embodiment
As can be seen that three embodiments are directed to different usage scenarios, corresponding tune has been done in position and arrangement to resonance coil 3
Whole, this is the field being not directed in traditional electromagnetic heater, and the new technology of use breaches traditional electromagnetic heating dress
The bottleneck set.
