Abstract
A burner shutoff for a burner, the burner shutoff including a solenoid moveable between an open position permitting fuel supply to the burner and a closed position cutting off fuel supply to the burner. The burner shutoff including a thermocouple in communication with the solenoid, wherein the thermocouple producing a voltage output signal when heated by the burner for maintaining the solenoid in the open position. The burner including a safety timer for selectively generating and communicating a reverse polarity voltage signal to the solenoid such that the voltage signal received by the solenoid is altered sufficiently to move the solenoid to the closed position, thereby shutting off the burner.
Claims21
A burner shutoff for a portable heater comprising;
- (a) a burner including a solenoid moveable between an open position permitting fuel supply to the burner and a closed position cutting off fuel supply to the burner;
- (b) a thermocouple in communication with the solenoid, wherein the thermocouple producing a voltage output signal when heated by the burner for maintaining the solenoid in the open position;
- (c) a safety timer for selectively generating and communicating a reverse polarity voltage signal to the solenoid such that the voltage signal received by the solenoid is altered sufficiently to move the solenoid to the closed position, thereby shutting off the burner.
A method of shutting off a burner, the method comprising:
- configuring a burner to comprise, a solenoid moveable between an open position permitting fuel supply to the burner and a closed position cutting off fuel supply to the burner, a thermocouple in communication with the solenoid, wherein the thermocouple producing a voltage output signal when heated by the burner for maintaining the solenoid in the open position;
- (a) igniting the burner,
- (b) generating a reverse polarity output signal,
- (c) communicating the reverse polarity voltage signal to the solenoid such that the voltage signal received by the solenoid is altered sufficiently to move the solenoid to the closed position, thereby shutting off the burner.
A system for shutting off a burner comprising;
- (a) a burner including a solenoid moveable between an open position permitting fuel supply to the burner and a closed position cutting off fuel supply to the burner;
- (b) a thermocouple in communication with the solenoid, wherein the thermocouple producing a voltage output signal when heated by the burner;
- wherein the voltage output signal received by the solenoid maintaining it in the open position;
- (c) a reset button for initiating a timer within a safety timer, the safety timer for generating and communicating a reverse polarity output signal to the solenoid such that the voltage signal received by the solenoid is altered sufficiently to move the solenoid to the closed position, thereby shutting off the burner.
