Here, SW2 and SW3 are switching elements of the setting function that can set the reservation minutes at the time of reservation, SW4 is a switching device of the reset function that can reset the reservation minutes at the time of reservation, for the convenience of the user.

The time and timer display unit 606 is installed to selectively display the current time and the reservation time according to the on / off operation of SW1.

In other words, the reservation time is displayed when SW1 is on, and the current time is displayed when SW1 is off.

The ambient temperature detecting unit 608 detects a sudden increase in the ambient temperature, and when the ambient temperature rises above the proper temperature range, the gas temperature valve is operated to block the gas to prevent a fire in the gas range. .

In this case, the ambient temperature sensor 608 uses the thermistor 102j which is a semiconductor device for temperature detection.

The motor driving unit and the alarm unit 610 are installed to generate a sound of a speaker electrically connected to the melody IC while the motor is selectively driven according to the on / off operation of SW1.

In other words, when SW1 is on, the melody IC is operated while the motor is driven by the switching signal of the timer module 104f ₅ , and the sound of the speaker is output according to the output signal of the melody IC. At this time, the SW1 (delayed linkage with SW1 of the central processing unit) uses a limit switch to drive or stop the motor 104e efficiently.

The central processing unit 612 selects a power supply and a preliminary power supply unit 602, a time and timer operation switch unit 604, a time and timer display unit 606, an ambient temperature sensor 608, a motor driver and an alarm unit 610. It is installed to operate by controlling and store the calculated value.
