A fire pit includes a plurality of detachable connection mechanisms, a plurality of wall bodies, a pressing frame, and a bearing plate. The wall bodies surround to form a chamber. The two adjacent wall bodies are connected to each other through the detachable connection mechanism. The pressing frame surrounds to form an opening that communicates with the chamber. The pressing frame is located at an upper portion of the chamber and provides a first horizontal force to push against the wall bodies. The bearing plate is adapted to bearing fuel placed in the chamber. The bearing plate is provided with a plurality of through holes that communicate with the chamber. The bearing plate is located at a lower portion of the chamber and provides a second horizontal force to push against the wall bodies.

A smokeless fire pit may include a fire pit base, a top rim, an ash tray assembly, and a cylindrical chamber wall. The fire pit base defines an interior region and defines a plurality of apertures that provide air passageways for air to flow from outside of the fire pit base and into the interior region defined by the fire pit base. The fire pit is configured to provide a primary air flow from the plurality of apertures at the fire pit base, into the interior region, and through the ash tray assembly into a burn chamber defined by the cylindrical chamber wall. Further, the fire pit is configured to provide a secondary air flow from the plurality of apertures at the fire pit base, into the interior region, and through a plurality of holes defined by the cylindrical chamber wall into the burn chamber near the top rim.

Grill cookboxes including dual-lipped lower rims are disclosed. An example cookbox includes an interior surface, an exterior surface, and a lower rim. The exterior surface is located opposite the interior surface. The lower rim is located along a bottom portion of the cookbox. The lower rim includes an inner lip, an outer lip, and a downwardly facing channel. The inner lip defines an opening formed in the bottom portion of the cookbox. The downwardly facing channel extends between a free end of the inner lip and a free end of the outer lip.

A cooking grill with a cooking chamber, pellet fuel combustion unit, and ash cleanout system for releasing retained ash from the combustion unit through an access door without requiring the disassembly of the upper components of the grill. The combustion unit has a first end with a first end opening, and a second end with a second end opening. The ash cleanout system includes an access door adjacent to the second end, operable by a user from a position external to the cooking chamber through a pull link, and capable of a first position wherein the second end opening is closed to generally retain ash within the pellet fuel combustion unit, and a second position wherein the second end opening is open to release the retained ash to a separate removal location.

A pellet burner includes: a burner body having a combustion chamber and an open top; a feed opening at a sidewall of the burner body; a through port under the burner body; and a grate structure above the through port and including two tiers of supports both secured to the burner body. Supports in the first tier are lower than the adjacent supports in the second tier. The second tier of supports are staggered with the first tier. A passage is between the two tiers of supports. The passage is narrower than a diameter D of the pellet fuel. A spacing between two adjacent supports in the second tier is greater than D but smaller than 2D. The feed opening is above the grate structure by no less than 3D. The pellet fuel drops from the feed opening. Air entering via the through port disperses the burnt pellet fuel ash.

A fire pit barrier may help reduce the likelihood of contact with a side of a fire pit. The fire pit barrier may include a frame couplable to the fire pit. The frame may include a top support, a bottom support, and at least one connector extending between the top support and the bottom support. The frame may also include a shield coupled to the frame. The fire pit barrier may be configured to cover an outer surface of the fire pit and inhibit heat transfer from the fire pit to an exterior side of the shield.

A firepot for a grilling device comprises one or more walls at least partially forming an outer boundary of the firepot. The firepot is structurally configured to hold at least partially ignited solid fuel. The firepot also comprises a floor defining, at least in part, a lower end of the firepot. The floor comprises one or more holes extending through the floor. Additionally, a portion of the one or more walls form a solid fuel delivery opening that comprises a solid fuel portal through which solid fuel is deliverable to an interior of the firepot. A heating element mount is positioned to hold a heating element within the interior of the firepot.

A heating device, preferably for the combustion of biomass, in particular of pellets of biomass, in one aspect, includes a burner part and a heating part. The burner part includes a combustion chamber; a double-walled, internally hollow combustion-chamber wall, which has an upper opening leading above the combustion zone into the combustion chamber; a flue-gas duct which leads the flue gas downwards along the combustion chamber, wherein the flue-gas duct is followed by a heat-exchanger area including initially, a flat-tube flue-gas heat exchanger, then, a tertiary-air heat exchanger; a flue-gas ventilation stack, a radiant-heat exchanger located above the combustion chamber, a flue-gas flap at the upper end of the flue-gas duct, which, when open, connects the flue-gas duct to the stack. A flat-tube flue-gas heat exchanger of the heating part forms a heat-exchanger circuit with an exhaust-air heat exchanger with the same heat-transfer medium as the flat-tube flue-gas heat exchanger.

A heat deflector is disclosed that includes a first portion having a first outer edge and a center and a first surface extending from the first outer edge to the center of the first portion. The first surface sloping downward from the first outer edge toward the center of the first portion. The heat deflector further includes a second portion having an inner edge and an outer edge. The inner edge of the second portion is adjacent to the first outer edge of the first portion. The heat deflector further includes a third portion having a third outer edge and a third inner edge and a second surface extending from the third outer edge of the third portion to the third inner edge of the third portion. The second surface sloping downward from the third outer edge of the third portion to the third inner edge of the third portion.

A heat deflector is disclosed that includes a first portion having a first outer edge and a center and a first surface extending from the first outer edge to the center of the first portion. The first surface sloping downward from the first outer edge toward the center of the first portion. The heat deflector further includes a second portion having an inner edge and an outer edge. The inner edge of the second portion is adjacent to the first outer edge of the first portion. The heat deflector further includes a third portion having a third outer edge and a third inner edge and a second surface extending from the third outer edge of the third portion to the third inner edge of the third portion. The second surface sloping downward from the third outer edge of the third portion to the third inner edge of the third portion.
