なった。What is common to the above-mentioned prior arts is that a method of setting a fire extinguishing temperature and extinguishing a fire when the temperature is reached is adopted. For this reason, there is a case where the food is not adapted to the food in the pot or the heat, and the food is scorched. For example, when cooking food with a "thickness" such as curry in a small amount compared to the diameter of the pot, the food in the pot at that time becomes shallow. In such a state, heating with a large fire (approximately 2300 kcal / h) without squeezing the heating power results in a large heating power, and the content is "thick", so it is easy to burn and the temperature sensor that detects the temperature at the bottom of the pot And the temperature difference with the outer peripheral part in a pan becomes large. For this reason, when the temperature detected by the temperature sensor is scorched and reaches the heating stop temperature,
Already, the curry in the pot has been burnt black.

And comprises a CPU and the like. Next, the heating and cooking apparatus of the present invention will be described based on the flowchart of FIG. First, the main plug 2 is opened, an activation signal is supplied to the gas supply control device 3 by a manual operation means (not shown), and an ignition device (not shown) is operated.
Ignite. At this time, a signal for adjusting the gas supply amount to the gas burner 1 is given to the gas supply control device 3 by the manual operation means, and the combustion of the gas burner 1 is manually adjusted so as to obtain a desired heating power.

る。Now, when the gas burner 1 is ignited and the food 6 is heated through the pot 6, the pot bottom temperature rises with the lapse of time. The signal processor 7 monitors the rise in temperature at this time. As shown in FIG. 3, when the pot bottom temperature rises to a predetermined constant temperature T 1 ° C. slightly before the boiling temperature of water, the time t 1 during which the temperature rises and passes through the constant temperature range from T 1 ° C. to T 2 ° C. measured, and stores the value t 2 multiplied by a predetermined coefficient to the measured value t 1 as a reference value of the boiling point detection.

しないので上記比較は行わない。The signal processing unit 7 determines the time t required for the temperature to rise every time the detected temperature reaches the boiling temperature of water or a temperature in the vicinity thereof, and the stored reference value t 2. comparing the door, and time t exceeds the reference value t 2, food 8 is determined to be in a boiling state. Further, the signal processing unit 7 performs a predetermined time t 0 from the boiling state detection time ta or a predetermined time after the detection time ta.
Each time, the temperature detected by the temperature sensor 6 is sampled, a difference between the temperature detected in the previous sampling and the temperature detected in the current sampling is obtained, and the obtained temperature difference is compared with a predetermined judgment value. If there is a temperature difference larger than the value, the count value of the built-in counter of the signal processing unit 7 (actually processed by software by the CPU) is counted up. At the time of the first sampling, the above-mentioned comparison is not performed because there is no previous detected temperature.

値に基づいて定めた値である。The count value N of the above-mentioned counter is reset to 0 each time the state where there is a temperature difference equal to or greater than the judgment value is continued, and is incremented by 1 only when the state is continuous. Then, the signal processing unit 7 determines that there is a risk of burning when the count value N exceeds a predetermined value Na. The count value Na and the above-mentioned determination value are values determined based on the actually measured value at the time of observing the state in which the food 3 such as curry with “thickness” is actually cooked and its scorching occurs.

To the gas burner 1
The combustion of is set to a small fire. If the user does not extinguish the gas burner 1 with the manual operation means, the signal processing unit 7 further monitors the temperature rise while maintaining the small fire state, and the temperature detected by the temperature sensor 6 reaches the predetermined fire extinguishing temperature. Then, a signal for stopping the gas supply is given to the gas supply control device 3 to forcibly extinguish the fire and prevent burning.
