Indicates the song song. Figure 1 shows an example of an automatic temperature control device for a gas staple stove. Gas flowing in from gas station 1 is branched into a passage that runs from manual gas station 2 through safety valve 3 to pilot burner 4 and main burner 5. .

ように出力する。A control valve 6 is provided in a passage leading to the main burner 6t, and controls the main burner 5 on and off. Reference numeral 7 is a control circuit that detects that the p-gas stove is in use by a switch 2 interlocked with the gas cock 2, outputs an output to open the safety valve 3, and ignites the pilot burner 4 with an igniter (not shown). A temperature sensor 8 detects the temperature of the food 9 and compares it with the set temperature of the setting variable resistor 10, and outputs an on/off signal for the control valve 6. As a result, the main burner 5 is controlled on and off, but the pilot burner 4 continues to burn while the safety valve 3 is open. 11
The combustion detector detects when the pilot burner 4 misfires or fails to ignite, and the control circuit 7 outputs an output to close the safety valve 3.

災等の発生の原因となり非常に危険である。こねにガス
オーブンや電気コンロにつ込ても同じことがifえる。Here, when the temperature of the sensor 8 is higher than the set temperature of the variable resistor 10, the main burner 5 is extinguished and only the pilot burner 4 is in a state of combustion. In order to improve cooking performance, it is desired that the pilot burner 4 burns as little as possible, making it difficult for humans to check the combustion of the pilot burner. Therefore, if the user mistakenly assumes that all burners are extinguishing the main burner 5 and removes the food 9, the pilot burner 4 will continue to burn at any time, depending on the state of the sensor 8. This is extremely dangerous as the main burner 5 may also open and cause a fire. The same thing would happen if you put the dough in a gas oven or electric stove.

では2時間程度が好ましいと考えられる。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. FIG. 2 is a system diagram showing an example in which the present invention is applied to a gas stove. In Figure 2, parts that are the same as those in Figure 1 are marked with the same symbols. The control circuit 7 has a built-in safety timer 12, and the safety timer 12 is controlled by the switch 2 which is linked to the cock 2.
Counting starts from the time it is detected that the cock 2 is opened, and if the cock 2 is not closed even after a predetermined period of time has elapsed, a closing output is automatically sent to the safety valve 3 to extinguish the burner 5. Although the predetermined time of the safety timer 12 differs depending on the cooker, by selecting a time longer than the time used for normal cooking, the user may feel inconvenienced. It is thought that about 2 hours is preferable for stovetops, open doors, etc.

Immediately after turning on, the safety timer 12 starts, and the safety valve 3 and control valve 6 are opened. (Cooking start section ■) Normally, the temperature sensor 8 and the set temperature 10 are compared, and the roof flow passes through the control valve 6 and the temperature control section II which controls opening and closing. The loop ■ includes a burner extinguishing section IY that closes the safety valve 3 when the cock 2 is closed midway or when the burner 5 misfires, and a safety timer 12 is preset in this burner extinguishing section lv. The structure also has a function of closing the safety valve 3 when the time count is completed. When the cock 2 is closed before the safety timer 12 counts up the time, the safety timer is initialized, and when the cock is opened again, the safety timer is reset.
