Description
Technical field
The utility model relates to a kind of electric pressure cooking saucepan, particularly a kind of electric pressure cooking saucepan that has electromagnetic heater.
Background technology
At present, the mode of heating of electric pressure cooking saucepan all is to adopt common heat-generating pipe heating, and heat-generating pipe itself generates heat, and by heat conducting mode heat is passed on the pot again, like this, just has the heat of quite a few to scatter and disappear, and its thermal efficiency is low, speed is slow, dangerous.And the pot body is generally simple plane or cambered surface, and bad adaptability is placed not steady.
The utility model content
Low in order to overcome existing electric pressure cooking saucepan heating efficiency, the defective that heat leakage is bigger, the utility model provides a kind of electric pressure cooking saucepan that has electromagnetic heater, its electromagnetic heating drum is flat and arcuate bottom combines, to improve the thermal efficiency, and make that it is energy-conservation, cleaning, safety, the pot body is placed steadily.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of electric pressure cooking saucepan that has electromagnetic heater comprises pot body and heater thereof, and its special character is: described heater is an electromagnetic heater, and described electromagnetic heater is arranged at the bottom of pot body.
According to the utility model, its special character is: the electromagnetic heating drum of described electromagnetic heater is flat and the arcuate bottom combination, described flat be in a pot body bottommost zone, described arcuate bottom and described flat joining.
According to the utility model, its special character is: the electromagnetic heating drum H that its control device comprises the M of control centre, is connected in the power circuit P of the M of control centre, anti-jamming circuit K, temperature sensing circuit ST, voltage detecting circuit SV, current detection circuit SI, heating control circuit C and is connected in heating control circuit C.Certainly also can according to circumstances add auxiliary circuits such as abnormal alarm circuit, mu balanced circuit, timing control circuit.
Its operation principle is as follows: after energising and the startup; entire circuit is started working; power circuit P uninterruptedly provides power supply for system; voltage detecting circuit SV; current detection circuit SI detects voltage and the electric current of supplying with heating coil disc in real time; temperature sensing circuit ST detects IGBT and rectifier bridge in real time; the temperature of pot; when overvoltage or under-voltage; overcurrent; during overtemperature; the M of control centre in time controls heating control circuit C; reduce or disconnection output; thereby can protect elements such as IGBT and rectifier bridge timely and effectively, anti-jamming circuit K can improve the antijamming capability of native system and suppress native system and send interfering signal toward the outside.
Other auxiliary circuit such as timing circuit realize that system will cut off output when setting-up time arrives.The abnormal alarm circuit is then realized abnormal failure occurring when native system, during cisco unity malfunction, or do not have pot and can in time send the indication of reporting to the police when being not iron pan, simultaneously, system can not be activated into duty, IGBT is in closed condition, guarantees that product can not generate heat under uncontrolled situation for a long time, causes the generation of accidents such as fire.
Because the utility model has adopted technique scheme, control the power on/off of IGBT by the high-frequency impulse more than the control circuit generation 15KHZ, high direct voltage after the rectification is supplied with the electromagnetic heating drum produce magnetic field, make the iron pan in the magnetic field produce eddy-current heating, the electromagnetic heating drum itself does not generate heat, particularly the electromagnetic heating drum is flat and arcuate bottom combine (as accompanying drawing 3), make that the magnetic field that produces is stronger, more effectively be applied on the iron pan, and can detect the nothing pot, be not the situation of iron pan, empty pot, prevent the generation of accidents such as fire effectively.
