Abstract
The present invention includes a fire pit and a system for using the fire pit that includes distinct structures. The fire pit includes an air inlet that allows in forced air for the coursing thereof through a hollowed housing for release through an air outlet. The fire pit may include a plenum that generates a virtual chimney of forced air that directs smoke upward and away from bystanders.
Claims17
A fire pit comprising:
- a housing surrounding an exposed central fuel cavity having a base and an apex and supporting a (i) radial, fluid channel, defined by an inner wall, circumscribing said cavity and an outer wall circumscribing said inner wall, in fluid communication with a fluid inlet, (ii) at least one radial shelf defining a helical fluid pathway within said housing, distinct from said fluid channel, and (iii) a fluid outlet in fluid communication with said pathway;
- and
- an annular plenum, in fluid communication with said radial fluid channel, defining an upper peripheral vent adapted to project a pressurized annular stream of fluid surrounding said apex of said cavity.
A fire pit system comprising:
- a fire pit comprising:
- a substantially sealed housing surrounding an exposed central fuel cavity having a base and an apex;
- an inner wall, circumscribing said cavity;
- and
- an outer wall circumscribing said inner wall;
- at least one radial shelf between said inner wall and said outer wall defining a helical fluid pathway in fluid communication with a fluid inlet and a fluid outlet;
- a blower in fluid communication with said fluid inlet;
- conduit in fluid communication with said fluid outlet;
- and
- a primary environmental fixture, positioned distant from said fire pit, having a body with a fixture surface thereon;
- an intake, in fluid communication with said conduit;
- a void in fluid communication with said intake;
- and a register, positioned on said fixture surface toward said fire pit.
