PURPOSE: An intermittent alarm device of a gas range is provided to prevent a user from forgetting if operating the gas range in cooking foods by generating an alarm sound at regular intervals. CONSTITUTION: An intermittent alarm device of a gas range generates an alarm sound for every 3,5, or 10 minutes. A time set function is operated by pressing an alarm function button(6), a first time set LED(Light Emitting Diode) is turned on, and accordingly, the time is set for 5, 10, 20, 30, or 60 minutes. The set time is increased for every time a user presses the alarm function button once and returned to the first step if pressing the button at the end of the time set. The set time and an intermediate alarm sound-set time are displayed on an LCD(Liquid Crystal Display). A rotary-type timer alarm device sets the time for 3 hours, makes intermediate alarm sounds for every 20 minutes, and makes the alarm sound every 5 minutes for 20 minutes before finish.
