In FIG. 1, 1 is a gas stove schematically shown, 2 is a burner, 3 is a gas passage to the burner 2, a main valve 4 and an electromagnetic gas valve 5 are interposed in the gas passage 3, and a gas passage is provided. 3 is provided with a bypass 3a bypassing the electromagnetic gas valve 5, and the bypass 3a is provided with an orifice 3b. When the main valve 4 is opened and the electromagnetic gas valve 5 is closed, a small amount of gas, for example, 400 k
Cal / h gas is supplied to the burner 2 to cause small combustion. When the electromagnetic gas valve 5 is opened in this state, a total of 4600 kcal / h of gas is supplied from the electromagnetic gas valve 5 and the bypass 3a to generate a strong fire. An electrode 7 faces a part of the flame opening 6 of the burner 2, a heat shield cylinder 8 and a temperature sensor 9 are arranged in the upper center of the burner 2. Is done.

The controller 11 transmits a signal corresponding to the temperature of the pot P detected by the temperature sensor 9 in advance to maintain the temperature of the food stored in the pot P at a predetermined temperature. As compared with the set reference level, the electromagnetic gas valve 5 is controlled to open and close, and the alarm 12 is further controlled.

A curve A indicates the temperature detected by the temperature sensor 9, a curve B indicates the open / closed state of the gas valve 5, and a curve C indicates ON / OFF of the alarm. In the sensor temperature, Th indicates a high reference temperature, Tl indicates a low reference temperature, and Ts indicates an alarm reference temperature. The controller 11 closes the gas valve 5 when the sensor temperature becomes equal to or higher than the high reference temperature Th when the gas valve 5 is open, and when the sensor temperature becomes equal to or lower than the low reference temperature Tl when the gas valve 5 is closed. , And when the sensor temperature reaches the alarm reference temperature Ts while the gas valve 5 is closed, the alarm is controlled to sound.

昇が生じないアンダーシュートである。When the gas valve 5 shown in FIG. 1 is opened, high temperature combustion is performed in the burner 2 by the gas passing through the gas valve 5 and the bypass 3a, and the detected temperature rises. When the temperature reaches the temperature Th, the gas valve 5 is closed, and the burner 2 performs the low heat combustion only by the gas passing through the bypass 3a. At the time of the low heat combustion, the natural cooling heat amount of the pot P is larger than the heating amount by the low heat combustion. When the temperature decreases and reaches the low reference temperature Tl, the gas valve 5 is opened, and high-firing combustion starts again. By repeating this operation, cooking is performed at the average temperature of the high and low reference temperatures Th and Tl. In the curve A, the peaks and valleys that go up and down from the straight lines indicating the reference temperatures Th and Tl of the high and low are overshoots in which the temperature rises a little after the gas valve 5 is closed and a low heat occurs, and the gas valve 5 This is an undershoot in which the temperature rise does not occur immediately after the open fire has occurred and a high fire has occurred.

に少しずれていてもよい。The alarm reference temperature Ts is set slightly higher than the low reference temperature Tl. When the temperature detected by the temperature sensor 9 falls below the alarm reference temperature Ts, an alarm is issued from the alarm 12 and the gas valve 5 opens. When the low reference temperature Tl is reached, the alarm is stopped. In addition, the timing to stop the alarm is to issue a warning and activate a timer, for example, a 2-second timer,
The alarm may be stopped when the timer ends. The end of the alarm in this case may be slightly shifted before and after the opening of the gas valve 5.
