める無負荷判定手段である。(Embodiment) In the figure, (1) is a temperature sensor having a built-in thermistor arranged at the center of a burner (3) as a heating means having a large number of flame openings (2) formed on the outer periphery thereof. (1) is urged upward by a spring (not shown),
As described above, the temperature sensor (1) is configured to contact the bottom of the pan with the pan placed on the pan (4). (5)
Is a gas passage to the burner (3), in which the main solenoid valve (6) is arranged in the most upstream and a proportional control valve (7) is arranged in the middle.
(8) is a temperature detection unit for detecting the temperature of the bottom of the cooking container such as a pan by the temperature sensor (1) at every predetermined sampling time. (9) drives the proportional control valve (7) to the output of the burner (3) that heats the pan, and has two stages (including medium and small fire) between high output (large fire) and low output (low flame). In the heat quantity switching means for switching to four stages, the value of the temperature sensor (1) output from the temperature detection unit (8) is compared with the preset temperature value, and the temperature of the pan bottom ( The cooking temperature) is kept almost constant at the set temperature. (10) stops combustion by the burner (3) when the detected temperature detected by the temperature sensor (1) reaches a predetermined high temperature (for example, 200 ° C.), and sets a predetermined low temperature (for example, 195).
It is an automatic point extinguishing means that restarts the combustion by the burner (3) when the temperature reaches (° C). (11) is a forced heating means for heating at a constant time (for example, 10 seconds) with a constant heating power (for example, 10 seconds) at the start of heating by the automatic point extinguishing means (10), and (12) is a temperature sensor (1) during this forced heating. The temperature rise rate of the detected temperature detected is calculated, and when the temperature rise rate is equal to or higher than a predetermined value, it means that there is no cooking container above the burner (3), and therefore the original solenoid valve (6) is closed. It is a no-load judging means for stopping the heating by the burner (3).

Now, assuming that the cooking mode is set to the tempura mode by a mode selection means (not shown), the set temperature is automatically set to 195 ° C. And it heats with a big flame until the output of the temperature sensor (1) becomes 195 degreeC. When it reaches 195 ℃, it switches to simmering heat to prevent further temperature rise. When the cooking ingredients are put in the pan, the oil temperature decreases, and when the temperature sensor (1) detects it, the oil is heated again by a large fire. This operation is performed by the heat quantity switching means (9) driving the proportional control valve (7) to keep the temperature of the bottom of the pan at about 195 ° C. However, if the user does other work and forgets to put the ingredients in the pan, the temperature at the bottom of the pan rises even if the heat is low. Then, when the temperature reaches 200 ° C, the automatic point extinguishing means (10) operates to stop the combustion of the burner (3). After that, when the ingredients are put into the pan again, the bottom temperature of the pan decreases and when it reaches 195 ℃, automatic fire extinguishing means (1
The burner (3) is ignited by 0).

の一定化がなされるのである。At this time, the burner (3) is overheated by the forced heating means (11).
It is combusted for 10 seconds. Since the pot is now placed, the temperature rise rate of the detected temperature detected by the temperature sensor (1) is low, so the no-load determination means (12) determines that there is a load,
Combustion is continued, and its heat power is set to a low heat by the heat quantity switching means (9). Once again, if the temperature rises to 200 ° C due to forgetting to put in materials, etc., automatic fire extinguishing means (1
Heating is stopped by 0). In this way, the cooking temperature is kept constant.

完全に停止してしまうのである。By the way, during the fire extinguishing by the automatic point extinguishing means (10), in order to distinguish from the case of the fire extinguishing by the manual operation, a warning is given to the user by blinking a lamp or ringing a buzzer. In the unlikely event that the user accidentally drops the pot. In such a case, it is dangerous for the automatic point extinguishing means (10) to repeat the point extinction forever. In such a case, the rate of temperature rise of the detected temperature detected by the temperature sensor (1) during the forced heating increases. When the rate of temperature rise exceeds a certain value, the no-load determination means (12) determines that there is no heating target, closes the original solenoid valve (6), and stops heating completely.

熱調理を行い得る効果がある。(Effects of the Invention) As described above, in the present invention, the heating amount switching means switches the heating means between the high output side and the low output side, whereby the cooking temperature of the cooking container can be maintained at the set temperature. Then, even if the cooking temperature rises by deviating from the set temperature, since the automatic fire extinguishing means performs the fire extinguishing / ignition operation within the predetermined temperature range including the set temperature, the cooking temperature can be maintained within the predetermined temperature range, There is an effect that appropriate cooking can be performed at a temperature near the set temperature.

Since it is stopped, there is an effect that it is also excellent in safety. In particular, it is safe even when the user mistakes the fire extinguishing by the automatic point extinguishing means for the fire extinguishing by the normal manual operation.
