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 ambient heating positioned in or proximate the at least one compartment;
a second heat source positioned within the top member and directly above the first heat source; and
a first shielding member configured to at least partially shield heat emanating from the first heat source towards the second heat source,
wherein the side members include one or more openings configured to allow propagation of the ambient heating emitted from the first heat source.

2. The multi-heat source fire pit apparatus according to claim 1 , wherein the side members extend vertically from the top member, the top member defining opposing first and second lateral ends in a first direction and a proximal end and an opposing distal end in a direction transverse to the first direction, the top member with side members forming the at least one.

3. The multi-heat source fire pit apparatus according to claim 2 , wherein the second heat source is a burner assembly and configured to produce an open flame by combusting fuel received from a fuel source.

4. The multi-heat source fire pit apparatus of claim 3 , wherein the burner assembly provides convection heat transfer and/or conduction heat transfer.

5. The multi-heat source fire pit apparatus according to claim 2 , wherein the first heat source is an infrared (IR) emitter positioned in the at least one compartment.

6. The multi-heat source fire pit apparatus of claim 5 , wherein the IR emitter is configured to convert electrical energy into IR radiation.

7. The multi-heat source fire pit apparatus of claim 5 , wherein the IR emitter is configured to convert energy from fuel in a fuel source into IR radiation.

8. The multi-heat source fire pit apparatus according to claim 1 , wherein the side members are positioned proximate the first heat source.

9. The multi-heat source fire pit apparatus of claim 1 , 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.

10. The multi-heat source fire pit apparatus of claim 1 , wherein:
the first heat source is structured to produce a first ambient temperature at a predetermined location at a first distance away from the multi-heat source fire pit apparatus; and
the first ambient temperature is greater than or equal to a second ambient temperature produced by convection heat transfer from the second heat source at the predetermined location.

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

12. 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, 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.

13. The multi-heat source fire pit apparatus of claim 1 , wherein the fire pit housing comprises a second shielding member between the first heat source and a fuel source, wherein the second shielding member is configured to inhibit heat emitted by the first heat source from propagating therethrough.

14. The multi-heat source fire pit apparatus of claim 13 , wherein the fire pit housing 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.

15. 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 ambient heating and positioned in or proximate the at least one compartment;
a second heat source positioned on the fire pit housing and directly above the first heat source and configured to produce heat from a fuel source; and
a first shielding member configured to at least partially shield heat emanating from the first heat source towards the second heat source,
wherein the side members are positioned proximate at least the first heat source, and
wherein the side members include one or more openings structured to allow propagation of heat emitted from the first heat source.

16. A multi-heat source fire pit apparatus comprising:
a fire pit housing comprising a top surface having side members to form a storage area configured to receive a heat source;
a first heat source configured to produce ambient heating and positioned in or proximate the storage area and configured to emit heat or radiation;
a second heat source positioned directly above the storage area and the first heat source and configured to produce heat by fuel received from a fuel source; and
a first shielding member configured to at least partially shield heat emanating from the first heat source towards the second heat source,
wherein the side members are positioned proximate the first heat source, and
wherein the side members include one or more openings structured to allow propagation of heat emitted from the first heat source.

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 and the second compartment is configured to receive a first heat source configured to produce ambient heating;
a second heat source positioned on the housing and directly above the first heat source configured to produce heat by fuel received from the fuel source; and
a first shielding member configured to at least partially shield heat emanating from the first heat source towards the second heat source,
wherein the housing includes one or more openings structured to allow propagation of heat emitted from the first heat source.

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 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.
