Abstract

The present disclosure is directed to a multi-heat source apparatus. The multi heat source may include a fire pit and is configured to provide ambient heating with both convection heat transfer and radiation heat transfer. The multi-heat source apparatus comprises an infrared emitter for generating infrared radiation. The multi-heat source apparatus comprises a shielding member between a heat source for the convection heat transfer and another heat source for radiation heat transfer.

First claim

What is claimed is:

1. A multi-heat source fire pit apparatus comprising:
a fire pit housing comprising a top member with side members forming at least one compartment;
a first heat source configured to produce first ambient heating for a first surrounding region and positioned in or proximate the at least one compartment; and
a second heat source configured to produce second ambient heating for a second surrounding region and positioned within the top member and above the first heat source,
wherein the first surrounding region surrounds the second surrounding region, and
wherein a temperature provided by the first ambient heating is greater than a temperature provided by the second ambient heating at a predetermined position in the second surrounding region.

2. The multi-heat source fire pit apparatus according to claim 1 , wherein the first heat source is an infrared (IR) emitter.

3. The multi-heat source fire pit apparatus of claim 2 , wherein the IR emitter is configured to convert electrical energy into IR radiation.

4. The multi-heat source fire pit apparatus of claim 2 , wherein the IR emitter is configured to convert energy from fuel in a fuel source into IR radiation.

5. The multi-heat source fire pit apparatus of claim 1 , wherein the first heat source comprises a filament and a concave trough.

6. The multi-heat source fire pit apparatus according to claim 1 , wherein the second heat source is a burner assembly configured to produce an open flame by combusting fuel received from a fuel source.

7. The multi-heat source fire pit apparatus according to claim 6 , wherein the burner assembly provides convection heat transfer and/or conduction heat transfer.

8. The multi-heat source fire pit apparatus according to claim 1 , wherein the side members include one or more openings configured to allow propagation of the first ambient heating emitted from the first heat source.

9. The multi-heat source fire pit apparatus of claim 1 , wherein the fire pit housing is configured to inhibit propagation of heat from the first heat source along first, second and third inhibiting directions, and
wherein the third inhibiting direction is approximately 180 degrees relative to the first inhibiting direction and the second inhibiting direction is approximately 90 degrees relative to the first and third inhibiting directions.

10. The multi-heat source fire pit apparatus of claim 1 , further comprising:
a first shielding member configured to at least partially shield heat emanating from the first heat source towards the second heat source.

11. The multi-heat source fire pit apparatus according to claim 10 , wherein the first shielding member comprises a reflective coating on a surface proximate to the first heat source, and
wherein the reflective coating is structured to reflect incident radiation from the first heat source into a fuel source.

12. The multi-heat source fire pit apparatus of claim 10 , wherein the fire pit housing further comprises a second shielding member between the first heat source and a fuel source, and
wherein the second shielding member is configured to inhibit heat emitted by the first heat source from propagating therethrough.

13. The multi-heat source fire pit apparatus of claim 12 , wherein the fire pit housing further comprises a third shielding member that is arranged opposite the first shielding member, and
wherein the third shielding member is structured to inhibit heat emitted by the first heat source from propagating therethrough.

14. The multi-heat source fire pit apparatus of claim 1 , wherein the first surrounding region and the second surrounding region at least partially overlap.

15. The multi-heat source fire pit apparatus of claim 1 , further comprising:
a shielding cover, wherein the shielding cover at least partially covers the first heat source, and wherein the shielding cover inhibits the first ambient heating in at least one direction.

16. A fire pit apparatus comprising:
a fire pit housing comprising a top member having side members configured to form at least one compartment configured to receive a heat source;
a first heat source configured to produce first ambient heating for a first surrounding region and positioned in or proximate the at least one compartment; and
a second heat source configured to produce second ambient heating for a second surrounding region and positioned within the top member and above the first heat source,
wherein the first surrounding region surrounds the second surrounding region, and
wherein a temperature provided by the first ambient heating is greater than a temperature provided by the second ambient heating at a predetermined position in the second surrounding region.

17. A multi-heat source apparatus comprising:
a housing configured to form a first compartment and a second compartment, wherein the first compartment is configured to receive a fuel source;
a first heat source configured to produce first ambient heating for a first surrounding region and positioned in the second compartment; and
a second heat source configured to produce second ambient heating for a second surrounding region and positioned on the housing and above the first heat source,
wherein the first surrounding region surrounds the second surrounding region, and
wherein a temperature provided by the first ambient heating is greater than a temperature provided by the second ambient heating at a predetermined position in the second surrounding region.

18. The multi-heat source apparatus according to claim 17 , wherein the first heat source is an infrared (IR) emitter positioned in the first compartment.

19. The multi-heat source fire pit apparatus of claim 18 , wherein the IR emitter is configured to convert electrical energy or energy from fuel in a fuel source into IR radiation.

20. The multi-heat source apparatus according to claim 17 , wherein the second heat source is a burner assembly and configured to produce an open flame by combusting fuel received from the fuel source.

21. The multi-heat source fire pit apparatus of claim 17 , wherein the first surrounding region and the second surrounding region at least partially overlap.
