The course of work:
After connecting power supply, circuit will send a prompt tone of " dripping ", directly selecting this moment power to adjust key can not select, could adjust power after having only the mode of operation of selection, the circuit working pattern has three kinds, is respectively to boil, explode, fry, after selecting corresponding mode of operation, the CPU general accesses the duty of this pattern automatically, will introduce the course of work of three kinds of patterns respectively below.
Boil: when selecting " boiling " pattern, power setting is in the full power operation mode, duration and degree of heating maximum, and the working time is set at 30 minutes, the thermistor R in temperature sensing circuit tDetect temperature and reach setting value 105 when spending, CPU is by the 5Foot control system speech IC IC 3 10Pin sends " ding-dong! Water will be opened " voice suggestion, CPU sets these voice are connected to be put three times, in time handles with the prompting user, this moment, power was adjusted into 1/2 total power (third gear) automatically.This moment, the user can require to carry out power (duration and degree of heating) adjustment, working time adjustment according to the difference of the different food of " boiling " system, when reaching when the working time is set, CPU cuts off the electricity supply automatically by executive circuit, if when temperature sensing circuit detects temperature above 140 degree (dry combustion method), CPU cuts off heating power supply by executive circuit
Fry: when " stir-fry " pattern of selection, power setting is in the full power operation mode, duration and degree of heating maximum, and the working time is set at 10 minutes, the thermistor R in temperature sensing circuit tDetect temperature and reach setting value 200 when spending, CPU is by the 7Foot control system speech IC 12Pin sends " ding-dong! Can cooking! " voice suggestion; CPU sets these voice are connected to be put three times; surpass 300 when spending as temperature; in time handle with the prompting user; the user can require carry out power (duration and degree of heating) adjustment, working time according to the difference of the different food of " stir-frys " system and adjusted this moment; carry when pot turning over dish thermistor R in the temperature sensing circuit in the frying process tThe infinity of disconnection resistance, the relay J outage, power, timing are regulated and are suspended.When putting down pot, thermistor R in the temperature sensing circuit tOperate as normal, when reaching when the working time is set, CPU cuts off the electricity supply automatically by executive circuit.
Fried: when " exploding " pattern of selection, power setting is 4/5 full power operation mode, and the working time is set at 60 minutes, the thermistor R in temperature sensing circuit tDetect temperature and reach setting value 240 when spending, CPU is by the 6Foot control system speech IC IC 3 11Pin sends " ding-dong! Dish can have been exploded! " voice suggestion; CPU sets these voice are connected to be put three times; in time handle with the prompting user; this moment, the user can require carry out power (duration and degree of heating) adjustment, working time adjustment according to the difference of the different food of " explode " system; when reaching when the working time is set, CPU cuts off the electricity supply automatically by executive circuit.
More than in each pattern, if electrical equipment is out of control, temperature surpasses 300 when spending, machine will be cut off the electricity supply comprehensively, and power is adjusted into zero, the working time zero clearing detects complete machine and enters lock-out state, all buttons are all inoperative, buzzer BU 1Send 5 " dripping " sound and enter the failure safe guard mode to do alarm.Only pull out power supply and wait for 2-3 after second, can work on after inserting attaching plug again.
