Burner unit having a low voltage sensor
First Claim
1. A combustible fuel burner system, comprising:
- a burner unit;
a power source; and
a circuit interrupter unit including a switch electrically coupled between the power source and the burner unit, the switch having a closed state, wherein the burner unit receives operational electrical power from the power source, the switch moving from the closed state to an open state and electrically disconnecting the burner unit from the power source upon a voltage of the power source falling below an interruption threshold, and the switch, when in the open state, moving to the closed state upon the voltage of the power source being above a restoration threshold that is higher than the interruption threshold only after remaining in the open state for a predetermined delay interval.

Abstract
A combustible fuel burner system includes a burner unit, a power source, and a circuit interrupter unit. The circuit interrupter unit has a switch electrically coupled between the power source and the burner unit. The switch has a closed state, wherein the burner unit receives operational electrical power from the power source. The switch moves from a closed state to an open state and electrically disconnects the device from the power source upon a voltage of the power source falling below an interruption threshold. The switch, when in the open state, moves to the closed state upon the voltage of the power source being above a restoration threshold that is higher than the interruption threshold.

8. A combustible fuel burner system, comprising;
-
a burner unit; a battery; and a control unit electrically coupled between the power source and the burner unit, the control unit including electronic circuitry programmed to automatically control operation of the burner unit, the control unit further including switch also electrically coupled between the power source and the burner unit and a microprocessor programmed to move the switch from a closed state to an open state upon a voltage of the power source falling below an interruption threshold and, when in the open state, to move the switch to the closed state upon the voltage of the power source being above a restoration threshold that is higher than the interruption threshold only after remaining in the open state for a predetermined delay interval, the switch electrically disconnecting the burner unit from the power source when in the open state and electrically connecting the burner unit with the power source when in the closed state. - View Dependent Claims (9, 10, 11, 12, 13)
