On the other hand, the output unit 13 outputs a low level to the resistor 24 corresponding to the temperature T1. When the pot temperature is lower than T1, the voltage of the terminal of the comparator 21 is larger than that of the terminal, so the output of the comparator 21 becomes high level, and the input unit 12 receiving this controls the output unit 13 by the control unit 11. Then, the transistor 18 is continuously turned on to continue energizing the heater. On the contrary, when the pot temperature is higher than T1, the voltage of the terminal of the comparator 21 becomes smaller than that of the terminal,
The output of 21 becomes low level, and the input section 12 receiving this gives a signal to the control section 11, and the process proceeds to the next step 52 stored in the storage section 14. In step 52, when the pot temperature becomes higher than T1 and the output of the comparator 21 becomes low level, the input section 12 receiving this gives a signal to the control section 11, and the control section 11 notifies the arithmetic section 15 of the time. Start measurement. At the same time, the output unit 13 outputs a low level to the resistor 34 corresponding to the temperature θ1. When the temperature of the thermistor 32 located on the lid is lower than θ1, the voltage of the terminal of the comparator 31 is higher than that of the terminal, so the output of the comparator 31 becomes high level, and when it is higher than θ1, the voltage of the terminal of the comparator 31 is higher. Since it is smaller than the terminal, the output of the comparator 31 becomes low level. When it is higher than θ1, the input unit 12 gives a signal to the control unit 11 to stop the measurement of the time by the calculation unit 15 and determine the amount of the cooked food based on the length of this time. The amount of food to be cooked is divided into n levels for determination, and the determination amount is stored in the storage unit 14. Then proceed to step 53. In order to set the detection temperature of the pan temperature to n stages corresponding to the amount of the cooked food divided into n stages, n resistors 25 to 27 are connected to the output unit 13. Since the output unit 13 sets the detection temperature of the pan temperature in accordance with the amount of the cooking product stored in the storage unit 14, the resistors 25 to 27 are used.
One of the pans that corresponds to the detected temperature is fixed at a low level. Here, the values of the divided resistors 25 to 27 of the resistor Rx are set so that the detected temperature of the pot temperature becomes higher as the amount of the cooked food increases.

1. In addition, the pan temperature detection temperature is set in multiple stages according to the amount of food to be divided into n stages, so you can easily change the detection temperature to any temperature by changing the resistance value. Can be set to.

2. In addition, the amount of food to be cooked is set to n stages. When the amount of food to be cooked is within a predetermined range, one cooked temperature can improve the quality of rice. Therefore, a simple circuit configuration, that is, n

Next, in step 54, heating is performed according to the amount of food to be cooked. That is, by the output unit 13 connected to the resistor 16,
The transistor 18 is turned on and off to change the energization rate to the heater 20. The larger the amount of food to be cooked, the higher the duty ratio, and the smaller the amount of food, the lower the duty ratio.

Next, proceeding to step 55, it is determined whether the pot temperature is higher than the set temperature, when it is low, the process proceeds to step 54, when it is high, the next process,
Then, the process proceeds to the Murashi process of step 56. That is, when the temperature of the thermistor 22 for detecting the temperature of the pot is lower than the temperature set in step 53, the comparator 21 outputs a high level, and the input section 12 receiving this outputs a signal to the control section 11 and outputs the signal in step 54. Take action. Conversely, when it is high, the comparator 21
Outputs a low level, and the input section 12 that receives this outputs a control section
A signal is given to 11, and the process proceeds to step 56.

As described above, since the heating is performed according to the amount of the food to be cooked and the set temperature for proceeding to the next step can be varied, the food can be optimally cooked.

EFFECTS OF THE INVENTION Since the present invention is provided with the cooking amount determination means and the control means for varying the temperature detected by the pan temperature detecting means according to the cooking amount as described above, heating according to the cooking amount is performed. Since the cooking temperature can be changed and the cooking temperature can be changed, when the amount of food to be cooked is too low, too much heat will be burnt, and when the amount of food to be cooked is large, insufficient heating will result in insufficient moisture. The optimum heating and cooking temperature can be maintained according to the amount of food. Further, the circuit is simple and the number of parts can be reduced because the microcomputer can perform a series of control.

Since the detection temperature of the pan is set by dividing it into a plurality of n steps, the detection temperature can be easily set to an arbitrary temperature by changing the resistance value.
