Abstract

PURPOSE:To prevent the oxygen starvation in a room by extinguishing the burner and stopping the operation by providing a timer device that stops the operation at a certain elapsed time and multiple illuminators to indicate the operation time, said illuminators being disposed in a push button for reset switch. CONSTITUTION:A timer device 17 is energized upon turning on the power source switch 12, and illuminators 20, 20... are all turned on upon operation startup. When approximately 3hr has elapsed from the operation startup, the timer device 17 causes all the three illuminators 20, 20... to intermittently illuminate to inform users that it is about 3hr from the operation startup and the operation will soon be stopped. About 1-3min from the intermittent operation of the illuminators 20, 20..., the timer device 17 causes a normally closed switch 18 to be opened to interrupt the current to a main controller 14, and then, the burner 3 is extinguished and a hot air fan 4 is also stopped at the same time. Since the illuminators are disposed in a push button for reset switch, its location can clearly be identified by the intermittent operation of the illuminators.

Description
