Description
Technical field
The utility model relates to a kind of electromagnetic oven, particularly a kind of electromagnetic oven heating cup for automobile.
Background technology
In the prior art, automobile adopts heating wire with Heating Cup more, and the PTC ceramic component is as heater, and operating current is big, and the thermal efficiency is low, and is big to automobile storage battery harm.
Summary of the invention
For overcoming the above-mentioned deficiency of existing technology, the purpose of this invention is to provide a kind of energy-efficient automobile electromagnetic oven heating cup, its firing rate is fast, thermal efficiency height.
The utility model is taked following technical scheme: a kind of electromagnetic oven heating cup for automobile comprises insulation magnetic conduction cup, electromagnetic oven body; Described insulation magnetic conduction water tumbler is provided with level scale and takes into account Drinking cup lid, and Drinking cup lid is provided with thermometer; Described electromagnetic oven body is provided with the supply socket switch panel and the damping sucker is used for fixing electromagnetic oven body, is provided with heating spool rest, thermistor, supply socket, switch panel, fan electromotor, control circuit board in the described electromagnetic oven body; Described heating spool rest, thermistor, supply socket, switch panel, fan electromotor connect with control circuit board; Described control circuit board is by protective tube, smoothing choke, filter capacitor, high-frequency filter capacitor, heater coil disc, high-frequency resonant electric capacity, fast quick-recovery high-frequency diode, high-power IGBT pipe, power pushing circuit, fan electromotor, CPU central controller, thermistor, switch panel are formed.
Operation principle: the DC direct current is through protective tube, smoothing choke, filter capacitor, high frequency filter capacitor filtering, and this direct current constitutes the loop through heater coil disc and IGBT pipe.When the conducting of high-power IGBT pipe, the DC direct current charges to heater coil disc, and electric energy converts electromagnetic energy to and is stored in the heater coil; When the high-power IGBT pipe ends, heater coil charges to high-frequency resonant electric capacity, high-frequency resonant electric capacity 35 discharges to heater coil again immediately, week and recurrence beginning, be that heater coil and high-frequency resonant electric capacity constitute the shunt-resonant circuit, its resonant frequency is by the capacity decision of the inductance value and the high-frequency resonant electric capacity of heater coil.The high-power IGBT pipe with certain frequency work, produces 15KH in the heater coil under the driving of the PWM switching pulse of CPU central controller output
z-30kH
zHigh-frequency alternating current, so the flat powerful eddy current in ground that just produces of irony insulation magnetic conduction cup, flat rapid heating, the electromagnetic energy of heater coil is converted into heat energy.The ON time of control high-power IGBT pipe has promptly been controlled the energy storage size in the heater coil, thereby has been changed the power of eddy current, has reached the purpose of heat control.Its firing rate is fast, thermal efficiency height.

The specific embodiment
As shown in Figure 1 to Figure 3, a kind of electromagnetic oven heating cup for automobile comprises insulation magnetic conduction cup 1, electromagnetic oven body 2; Described insulation magnetic conduction water tumbler 1 is provided with level scale meter 5 and Drinking cup lid 6, and Drinking cup lid 6 is provided with thermometer 7; Described electromagnetic oven body 2 is provided with supply socket 4 switch panels 3 and damping sucker 8 is used for fixing electromagnetic oven body 1, is provided with heating spool rest 10, thermistor 11, supply socket 4, switch panel 3, fan electromotor 12, control circuit board 9 in the described electromagnetic oven body; Described heating spool rest 10, thermistor 11, supply socket 14, switch panel 3, fan electromotor 12 connect with control circuit board 9; Described control circuit board is by protective tube 31, smoothing choke 32, filter capacitor 33, high-frequency filter capacitor 35, heater coil disc 37, high-frequency resonant electric capacity 35, fast quick-recovery high-frequency diode 36, high-power IGBT pipe 38, power pushing circuit 39, fan electromotor 12, CPU central controller 310, thermistor 11, switch panel 3 are formed.
Operation principle: the DC direct current is through protective tube 31, smoothing choke 32, filter capacitor 33,35 filtering of high frequency filter electric capacity, and this direct current constitutes the loop through heater coil disc 37 and high-power IGBT pipe 38.When the conducting of high-power IGBT pipe, the DC direct current charges to heater coil disc, and electric energy converts electromagnetic energy to and is stored in the heater coil; When high-power IGBT pipe 38 ends, heater coil is to 35 chargings of high-frequency resonant electric capacity, high-frequency resonant electric capacity 35 discharges to heater coil again immediately, week and recurrence beginning, be that heater coil and high-frequency resonant electric capacity 35 constitute the shunt-resonant circuit, its resonant frequency is by the capacity decision of the inductance value and the high-frequency resonant electric capacity 35 of heater coil.High-power IGBT pipe 38 with certain frequency work, produces 15KH in the heater coil under the driving of the PWM switching pulse of CPU central controller 310 outputs
z-30kH
zHigh-frequency alternating current, so the flat powerful eddy current in ground that just produces of irony insulation magnetic conduction cup, flat rapid heating, the electromagnetic energy of heater coil is converted into heat energy.The ON time of control high-power IGBT pipe 38 has promptly been controlled the energy storage size in the heater coil, thereby has been changed the power of eddy current, has reached the purpose of heat control, and its firing rate is fast, thermal efficiency height.
