Claims

[Scope of utility model registration request]

The extinguishing time of a hot air heater that has a combustion fan, a burner that drips and burns oil, a heat exchanger, and a convection fan is determined by the cam attached to the output shaft of the program motor in the power circuit section and this cam. In a combustion control device controlled by a switching limit switch, a thermostat that closes when the temperature of the burner is below a predetermined temperature is provided in the power supply circuit, and a relay that is energized through a contact of the thermostat provided in the power supply circuit. The contacts of this relay and the limit switch are connected in series, and when the operation is stopped, the limit switch is closed after a certain period of time is measured by the cam, and when the burner temperature falls below a predetermined temperature, the limit switch is closed. A combustion control device characterized in that a thermostat is closed to enable restarting.
