Abstract

PURPOSE:To prevent an operator from failing to close a gas cock, by constituting a gas safety device in such a manner that an alarm repeats sounding until the gas cock is closed after a safety valve is automatically closed. CONSTITUTION:A safety valve controlling circuit 6 outputs an open valve signal, detecting an abnormal condition, when a gas cock 2 is not closed after a cooking is finished even though a safety valve 3 is closed and a burner 4 is stopped burning. At the same time a combustion is stopped, and an alarm device 8 built in an alarm circuit 7 starts sounding, and at the same time a timer 9 starts counting time, and every time when a predetermined time has passed, an alarm deiver 10 drives the alarm device 8 to repeat it alarming operation. When a manually operated gas cock 2 is closed, that is detected by a switch 2', and then alarming is stopped. In such a manner, alarming is repeated until an operator closes a gas cock, after a safety valve is automatically closed. With such an arrangement, the function of a safety device can be increased, since the gas cock remains closed even if the safety valve 3 happens to be opened again by an erroneous operation of a control circuit or by some other cause.

の流れ図に示す。5 is a combustion control circuit that detects when the gas stove is in use by switching in conjunction with the gas cock 2, and a safety valve control circuit 6.
outputs a valve opening output, ignites burner 4, and starts combustion. When cooking is completed or an abnormality occurs, the safety valve control circuit 6 outputs a valve opening output, the safety valve 3 is closed, and the combustion of the burner 4 is stopped. At the same time as the combustion stops, the alarm 8 built in the alarm circuit 7 gives an alarm, and at the same time the timer section 9 starts counting time, and the alarm drive section 10 drives the alarm 8 every predetermined time period to repeat the alarm. When the manual gas cock 2 is closed, it is detected by switching that the gas cock 2 is closed, and the notification is stopped. The flow of the above operation is shown in the flowchart of FIG.
