Abstract
A safety device for a pot-type oil burner is disclosed which is capable of efficiently and rapidly detecting the decrease of oxygen concentration in a room due to combustion to provide a warning and/or stop the combustion by sensing the decrease in temperature of a bottom portion of a pot. The safety device includes a thermo-sensitive device arranged on the outer surface of the bottom portion of the pot which is apart from the bottom region of the pot in which occurs the vaporization of fuel oil supplied to the pot.
