Abstract
A solid pellet fueled heater having a base unit with forced air blowers and a dual tube chimney structure is disclosed. The dual tube chimney structure may be used to warm incoming air for distribution around the heater. The pellet heater may also include a dual auger system and multi/high speed auger motor. The dual auger may include first and second auger blades mounted on a single auger shaft having blade pitches configured to convey solid fuel in opposite directions.
Claims19
A pellet fuel or solid fuel heater, comprising:
- a base structure;
- an intake housing;
- one or more blowers disposed within the base housing, said one or more blowers connected to the intake housing;
- one or more heat vents provided in the base housing;
- a burn pot housing disposed within the intake housing;
- a burn pot disposed within the burn pot housing;
- a pellet fuel or solid fuel hopper disposed within the base housing;
- and
- an auger system disposed within the base housing between the burn pot and solid fuel hopper,
- wherein said one or more blowers are configured to draw fresh air through said intake housing and direct the fresh air to the one or more heat vents.
A pellet fuel or solid fuel heater, comprising:
- a burn pot;
- a solid fuel hopper;
- an auger system disposed between the burn pot and solid fuel hopper;
- an electrical power supply;
- a spark generator electrically connected to the electrical power supply;
- a first electrode electrically connected to the spark generator, said first electrode having a first metallic tip extending into the burn pot;
- and
- a second electrode electrically connected to the electrical ground, said second electrode having a second metallic tip extending into the burn pot,
- wherein a gap space is provided between the first metallic tip and the second metallic tip, and
- wherein the spark generator is configured to create a continuous spark in the gap space between the first metallic tip and the second metallic tip for a duration greater than 2 seconds.
An outdoor solid fuel, gas fuel, or electric powered heater, comprising:
- a base housing having side walls;
- an intake housing disposed within the base housing;
- a first blower disposed within the base housing proximal to a first one of said side walls and connected to the intake housing;
- a second blower disposed within the base housing proximal to a second one of said side walls and connected to the intake housing;
- a first heat vent provided in the base housing proximal to said first blower;
- a second heat vent provided in the base housing proximal to said second blower;
- an inner housing disposed within the intake housing;
- a solid fuel, gas fuel, or electric powered heat source disposed within the inner housing;
- an outer tube sealed to and extending away from the intake housing through an opening in the base housing;
- and
- an inner tube disposed within the outer tube, said inner tube sealed to and extending away from the inner housing,
- wherein an outer tube passage is defined between the outer tube and the inner tube, said outer tube passage communicating with an interior of the intake housing,
- wherein an inner tube passage is defined by an interior of the inner tube, said inner tube passage communicating with an interior of the inner housing, and
- wherein said first blower is configured to draw fresh air through said outer tube passage and direct the fresh air to the first heat vent.
