As the further improvement of the technical program, be provided with cook indicator lamp 90 and insulation indicator lamp 91 in outer pot 1 outside; The indicator lamp 90 of cooking is connected with control module 94 after the first driving resistance R 9, and insulation indicator lamp 91 is connected with control module 94 after the second driving resistance R 10; Wherein, cook indicator lamp 90 and insulation indicator lamp 91 all are the LED lamps, and be shown in red when cooking indicator lamp 90 work, shown in green during 91 work of insulation indicator lamp.The temperature controller T1 that cooks can be the Kick type temperature controller of cooking, or bimetallic temperature controller, or the magnet steel temperature controller, or the NTC thermistor; Insulation temperature controller T2 can be bimetallic temperature controller.
Consult Fig. 4, the concrete operation principle of present embodiment is as follows:
In meal pot, install Mi Heshui, plug in and turn on the power switch 61 and make the pot for cooking rice energising, the voltage of power supply 6 forms the power supply of DC stabilization at the two ends of capacitor C 1 after overcurrent fuse 92, diode D1 and resistance R 1, its voltage swing is 24V, the power supply of this 24V gives relay 97 power supplies, simultaneously, this power supply forms the power supply of the 12V of DC stabilization again at capacitor C 2, voltage-stabiliser tube ZW1 two ends through resistance R 2, resistance R 3 backs, the power supply of this 12V gives control module 94 power supplies, promptly provides 12V power supply to model for the control module 94 of TC4069.
When just beginning to cook, the temperature of cook temperature controller T1 and insulation temperature controller T2 next door induction is all very low, so their contact all is a conducting state.The temperature controller T1 and the first divider resistance R5 cook, second divider resistance R6 series connection forms bleeder circuit 96, wherein 1 pin voltage of control module 94 is high voltage, they are 2 years old, the voltage of 3 pin is 0V, the first shunt resistance R7, the second shunt resistance R8 forms current-limiting circuit 95, the not conducting of base stage no-voltage of triode Q1, relay 97 not adhesives, so the time be the state of cooking, the normally-closed contact of relay 97 is without insulation temperature controller T2, it directly drives heat-generating disc 8 work, simultaneously, 4 of control module 94,5 pin voltages are high, so it is bright to drive the indicator lamp 90 of cooking through the first driving resistance R 9, it is shown in red, and 6 pin voltages of control module 94 are low-voltage, do not work so be incubated indicator lamp 91 no-voltages, at this moment are the state of normally cooking.
After after a while, after rice boils, after water evaporates is done, meal pot cooking bottom temperature rises when arriving the operating temperature of the temperature controller T1 that cooks, cook two contacts of temperature controller T1 disconnect not conducting, 1 pin no-voltage of control module 94,2,3 pin voltages are high voltage 12V and directly drive relay 97 adhesives, the normally opened contact of relay 97 is connected the electric current that insulation temperature controller T2 controls heat-generating disc 8, thereby insulation temperature controller T2 enters duty, and 4 and 5 pin voltages of control module 94 are low simultaneously, so no-voltage drives the indicator lamp 90 of cooking, do not work so cook indicator lamp 90 no-voltages, 6 pin voltages of control module 94 are high, and it is bright to drive resistance R 10 driving insulation indicator lamps 91 through second, and it is shown in green, insulation temperature controller T2 controls the temperature in meal pot automatically, at this moment is normal keeping warm mode.
When entering normal keeping warm mode after a period of time, meal pot cooking bottom temperature will descend, at this moment the cook contact of temperature controller T1 can be connected again, but triode Q1 conducting, diode D2 begins the forward conduction that works, and 1 pin voltage of control module 94 is dragged down drop to 0.6V, and 2,3 pin voltages still directly drives relay 97 adhesives for high voltage 12V, still make circuit maintain normal keeping warm mode, unless power switch 61 is disconnected once again.
Though described embodiment of the present utility model in conjunction with the accompanying drawings; but those skilled in the art can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present utility model, all should be within protection domain of the present utility model.
