Description
Technical field
A kind of device improving electromagnetic oven heating efficiency of the utility model, belongs to electromagnetic oven heating field.
Background technology
Electromagnetic oven utilizes electromagnetic induction principle to realize heating, and its thermal source is the Joule heat that in pot body, eddy current produces.In existing induction cooker system, the thermogenetic heat of joule is except heat food, and also some is along food conduct retrograde in the other direction, is dissipated in air and electromagnetic oven panel, causes electromagnetic oven heating efficiency to reduce.In addition, be dissipated in this part energy in electromagnetic oven panel, electromagnetic oven panel temperature can be caused to raise; Be heated for a long time and can make electromagnetic oven panel surface aging, reduce its service life.
Electromagnetic oven utilizes electromagnetic induction principle realization heating, namely in electromagnetic stove coil, passes into high frequency electric, forms high-frequency alternating magnetic field, and then produce induced-current at bottom of pot body, and the Joule heat that inductive loop produces is used for heating and cooking food.Have the advantages such as safety, convenient, clean, energy-saving and environmental protection because of it, current electromagnetic oven is used widely.
The physical process of electromagnetic oven heating food can be roughly divided into two parts: one be electromagnetic oven at the bottom of a pan induced-current, produce Joule heat; One is that Joule heat is by heat transfer heat food.In prior art, the mode increasing magnetic return path is usually adopted to increase Joule heat, to reach the object improving electromagnetic oven heating efficiency; But this mode increases the effect of electromagnetic oven heating efficiency and not obvious.Joule heat is by heat transfer in the process of heat foods, and greatly energy is along food conduct retrograde in the other direction, effectively solves the problem along food conduct retrograde in the other direction of Joule heat in electromagnetic oven heating process at present.
Chinese patent " a kind of low magnetic resistance anti-leakage efficient coil disc of electric stove " (CN201450617U), it is by increasing magnetic return path, reducing the mode of closed magnetic loop magnetic resistance, shield the leakage of the coil outer place magnetic line of force, thus improve the efficiency of heating surface of electromagnetic oven.This patent increases the Joule heat in electromagnetic oven cooker by the mode increasing magnetic circuit passage, but does not but consider the dissipation of Joule heat in heat transfer process.
Chinese patent " being placed in the basalt heatproof pad between electromagnetic oven panel and pot " (CN101012905A), it is 0.1-1mm, the basic basalt heatproof pad identical with electromagnetic oven panel of size by thickness, be placed between electromagnetic oven and pot, avoid mechanical damage and the Thermal Shock Damage of electromagnetic oven panel, reach the object extending electromagnetic oven panel service life.Although this patent has added basalt heatproof pad between electromagnetic oven panel and pot, the energy that it but can not stop pan sidewall outwards to dissipate, the efficiency of heating surface of electromagnetic oven has also improved a lot space.
In existing electromagnetic oven patent, in solution electromagnetic oven heating process all not yet in effect, Joule heat is along the problem of food opposite direction conduct retrograde.
Summary of the invention
The utility model provides a kind of device improving electromagnetic oven heating efficiency, effectively can suppress the conduct retrograde of Joule heat, makes more Joule heat by food absorption, thus improves the efficiency of heating surface of electromagnetic oven; Meanwhile, the energy be dissipated in electromagnetic oven panel will greatly reduce, and extend the service life of electromagnetic oven.
