The operation that utilizes the sour milk device of electromagnetic induction heating meal pot 300 making of the present invention will be described now.
In case will supply with the yogurt production device by user's operation from the electricity of power supply, it is pulsed dc voltage with the ac voltage rectifier of input then that alternating voltage just is added to first rectification unit, 100, the first rectification units 100.Pulsed dc voltage is transfused to the retardation coil L1 of advection unit 101 so that it is level and smooth.Voltage after level and smooth is received by transformer 108 and carries out step-down.Total alternating voltage is converted into DC voltage in second rectification unit 109, be transfused to system control unit 111 then.DC voltage also is used as the operating voltage of voltage detection unit 204 and triangular pulse generating unit 304.Simultaneously, current detecting unit 105 detects the AC power of input and produces voltage according to the result who is detected.Voltage from current detecting unit 105 is added on the input of negative-feedback amplifying unit 106.
After pouring in the metal pan 202, an amount of Mi Heshui selects the key that boils on the main control unit 110, then connect power supply, at this moment the function that boils has been selected in system control unit 111 control displays 124 demonstrations, the corresponding reference grade value that system control unit 111 is also carried a desired suitable temperature of the process that boils (for example, 120 ℃) to negative-feedback amplifying unit 106.
Negative-feedback amplifying unit 106 compares the voltage of current detecting unit 105 outputs and the reference voltage of system control unit 111 outputs, thereby by relatively obtaining a deviation.This deviate is delivered to integrated unit 107, and integrated unit 107 compiles deviate and be input to through diode D2 the non-change of current end of comparing unit 305.
Comparing unit 305 is transported to switch drive unit 104 with the pulse width modulating signal of high level, and is as mentioned below, and switch element TR1 is connected in response to pulse width modulating signal in switch drive unit 104, thereby sets up a resonant tank.As a result, the pulsed dc voltage of advection unit 101 output produces resonance by actuating coil L1 and resonant capacitor C2, so that a large amount of resonance currents actuating coil 203 of flowing through.
The resonance current that flows through actuating coil 203 produces magnetic field, and eddy current is brought out in this magnetic field in metal pan 202.As a result, metal pan 202 is heated, thereby makes the interior food of pot be heated to the temperature of hope.
Resonance potential between voltage detection unit 204 detection inverter unit 102 interior two nodes 96 and 97 is transported to it pulse width modulating signal generating unit 205 then at this moment.Based on the output voltage of voltage detection unit 203, the triangular pulse generating unit 304 of pulse width modulating signal generating unit 205 produces a triangular pulse signal, and it is transfused to the change of current input of comparing unit 305 again.
Behind the triangular pulse signal that receives from triangular pulse generating unit 304, comparing unit 305 is compared the signal of triangular pulse with integrated unit 107 outputs that are added to its non-change of current end, thereby the output pulse width modulation signal is with the switch number of times of the switch element TR1 of decision inverter unit 102.According to pulse width modulating signal from comparing unit 305, switch drive unit 104 gauge tap elements T R1, thus so that opening or closing, resonant tank drives actuating coil 203 effectively.Therefore, the food in the metal pan 202 is heated effectively with the process of boiling.
In the above-mentioned process that boils, system control unit 111 receives the output signal (a temperature-sensitive indication) that places the bottom temperature detector 122 below the metal pan 202 by the 3rd A/D converter 123, and with its with the predetermined suitable temperature value that is used to the process of boiling (for example, 120 ℃) compared, when temperature detector 122 detected temperature in bottom reach predetermined temperature (120 ℃), system control unit 111 determines that the process of boiling will be done, and carries out a control then to finish the process of boiling.In order to carry out the decatize process, system control unit 111 flows to 106 1 of negative-feedback amplifying units subsequently and is used for the temperature required reference value of decatize process.
The temperature required reference value of system control unit 111 output decatize processes is transfused to the non-change of current terminal of comparing unit 305 by negative-feedback amplifying unit 106 and integrated unit 107, and this reference value is set as less than the desired value of the process of boiling.This variation of reference value causes the variation of the pulse width modulating signal of pulse width modulating signal generating unit 204 outputs.Promptly open the switch element TR1 of inverter unit 102 by 104 short time of switch drive unit of pulse width modulating signal control.As a result, the driving time of actuating coil 203 is shortened, thereby reduces the temperature of metal pan 202 gradually.Like this, carry out the decatize process.
When the decatize process was finished subsequently, the user operated and selects insulation ammonium button to carry out insulating process.System control unit 111 enters the insulation pattern in response to the selection control side heater driver element 116 and the upper portion heater driver element 114 of insulation button to drive side heater 117 and upper portion heater 115.By heater 115 and 117 heats that produce, the food insulation in the metal pan 202.In this insulation operation, system control unit 111 by temperature detector 119 and the 121 and first and second A/ D converting units 118 and 120 periodically detect metal pan 202 internal temperature so that food remain on the suitable holding temperature.
In order to use electromagnetic induction heating meal pot to make sour milk with the above-mentioned function that boils, at first an amount of milk and sour milk are contained in container 127 (Fig. 2), again they are mixed.Container 127 that this mixture be housed put into metal pan 202 that suitable quantity of water 128 be housed thereafter.Under this condition, the user selects the sour milk button on the main control unit 110.
The manufacturing process of sour milk now will be in conjunction with the detailed in addition description of Fig. 3 to Fig. 5.
In case select sour milk ammonium button, system control unit 111 just control fans drive unit 112 with driving be positioned at the electromagnetic induction heating meal stew 300 bottoms cooling fan 113 to first scheduled time t1 (for example, 16 seconds), the internal temperature of meal pot 300 is maintained at the state (step 10) that balances each other with environment temperature like this.
First scheduled time t1 was after the past, and system control unit 111 is opened a timer (not shown) that is mounted in it, and drives it to second scheduled time t2 (for example, 10 minutes) (step 12).After this, the load factor indication of the switch time percentage of the switch element TR1 of system control unit 111 selection transverters 102 is used for the actuating coil 203 of heating of metal pot 202 with control.For the internal temperature that increases metal pan 202 and make it remain on 44 ℃, system control unit 111 flows to negative-feedback amplifying unit 106 with the load factor of highest ranking, be the load factor (comprising 16 seconds turn-on time and 0 second turn-off time) of 16:0, as shown in Figure 5.
After the load factor of system control unit 111 receiving key elements T R1, negative-feedback amplifying unit 106 compares the value that received and electric pressure from current detecting unit 105, thereby generates a deviation, then with its input integrated unit 107.Deviation is compiled the back is fed to comparing unit 305 by diode D2 non-change of current end in integrated unit 107.
The value of compiling from integrated unit 107 that comparing unit 305 will be input to its non-change of current end compares with the triangular pulse from triangular pulse generating unit 304 that is input to change of current end, thereby produces the pulse width modulating signal of switch number of times of the switch element TR1 of a definite transverter 102.Pulse width modulating signal is transfused to switch drive unit 104.Because switch drive unit 104 is according to pulse width modulating signal and controlled, switch element TR1 is opened to second scheduled time t2 (10 minutes) that is set by the timer (not shown) continuously, as a result, actuating coil 203 is actuated to heating of metal pot 202 with its maximum output state.
Along with the heating of metal pan 202, the mixture in the container 127 also is heated.Because the heat of metal pan 202 is to pass to container 127 by the water 128 that are contained in the metal pan 202, so the internal temperature of container 127 can not rise rapidly, but rising gradually is even also be like this when metal pan 202 is heated with the maximum load rate.Like this, mixture is nursed one's health first.
In said process, system control unit 111 is checked whether over and done with (step 14) of second scheduled time t2 (10 minutes) by timer.
When second scheduled time t2 does not also have past tense, system control unit 111 detects the temperature of metal pan 202 by bottom temperature detector 123 and the 3rd A/D converting unit 124, then detected temperature and the first predetermined temperature T1 (for example, 44 ℃) are compared (step 16).
When the temperature of metal pan 202 does not also reach the first predetermined temperature T1 (44 ℃), the switch element TR1 of system control unit 111 control transverters 102 with keep present drive condition advance in response to the connection that comprises 16 seconds between and the 16th grade of load factor of turn-off time of 0 second reach the first predetermined temperature T1 until the temperature of metal pan 202, thereby drive actuating coil 203 continuously with heating of metal pot 202 (step 18).In case the temperature of metal pan 202 reaches the first predetermined temperature T1, whether the switch element TR1 of inverter unit 102 just ignores second scheduled time t2 (10 minutes) and reaches and disconnect so that the temperature of metal pan 202 remains on the first predetermined temperature T1 (44 ℃).
On the other hand, when the temperature of metal pan 202 when second scheduled time t2 reaches the first predetermined temperature T1 after (10 minutes) past, system control unit 111 is opened and is contained in another inner timer (not shown), and drives it to the 3rd scheduled time t3 (for example, 190 minutes) (step 22).For the internal temperature that keeps metal pan 202 in the second predetermined temperature T2 (for example, 39 ℃), system control unit 111 flows to negative-feedback amplifying unit 106 with first order load factor, i.e. the load factor of 1:15 (comprising the turn-on time in 1 second and 15 seconds turn-off time), as shown in Figure 5.
According to the load factor of the switch element TR1 of inverter unit 102, comparing unit 305 by pulse width modulating signal of process output same as described above to determine the switch number of times of switch element TR1, with this gauge tap driver element 104.According to the output signal of switch drive unit 104, the 3rd scheduled time t3 (190 minutes) that sets by relevant timer that is operated to that switch element TR1 repeats to connect 1 second, disconnects 15 seconds.As a result, actuating coil 203 is actuated to heating of metal pot 202 with its minimum output state.
In this course, system control unit 111 detects the 3rd scheduled time t3 (190 minutes) whether over and done with (step 24) by timer.
When the 3rd scheduled time t3 past tense not as yet, system control unit 111 detects the temperature of metal pan 202 by bottom temperature detector 123 and the 3rd A/D converting unit 124, then with detected temperatures and the second predetermined temperature T2 (39 ℃) compare (step 26).
When the temperature of metal pan 202 does not also reach the second predetermined temperature T2, the switch element TR1 of system control unit 111 control converters 102 reaches second predetermined temperature T2 in response to the first order load factor of turn-off time that comprises 1 second turn-on time and 15 seconds up to the temperature of metal pan 202 to keep present drive condition, thereby drives actuating coil 203 with heating of metal pot 202 (step 28).In case the temperature of metal pan 202 reaches the second predetermined temperature T2, whether the switch element TR1 of inverter unit 102 just ignores the 3rd scheduled time t3 (190 minutes) and reaches and disconnect (step 30), makes the temperature of metal pan 202 be maintained at the second predetermined temperature T2 (39 ℃).Like this, mixture is nursed one's health for the second time, thereby produces the sour milk of optimum state.
On the other hand, when the temperature of metal pan 202 when the 3rd scheduled time t3 reaches the second predetermined temperature T2 after (190 minutes) past, system control unit 111 has just been finished the manufacturing process of sour milk.
Though as above-described, the invention provides a kind of method of using electromagnetic induction heating meal pot to make sour milk, comprise: actuating coil heating milk mixture to a predetermined temperature (44 ℃) that drives meal pot with the maximum load rate, when milk mixture reaches predetermined temperature, drive actuating coil with at optimum fermentation temp (39 ℃) conditioning milk mixture down with the minimum load rate again, thereby no matter the milk mixture amount what and can make the sour milk of optimum state at short notice.Therefore, can reduce the consumption of electric power according to the present invention, also can improve aspect the efficient of time and economy.In addition, can also eliminate because the yogurt production quantitative limitation that the finite size of yogurt production container brings.
