Abstract

An apparatus includes a bottom, a top including an opening, a first sidewall coupled to the top and the bottom, a second sidewall coupled to the top and the bottom, an interior defined at least in part by the bottom, the top, the first sidewall, and the second sidewall, and a central vertical axis. A first vane couples to the first sidewall, within the interior, and follows a spiral trajectory about the central vertical axis in a direction between the bottom and the top. A second vane couples to the second sidewall, within the interior, and follows a spiral trajectory about the central vertical axis in the direction between the bottom and the top.

an interior of the fire pit is defined at least in part by the bottom, the top, the first half-circular section, and the second half-circular section;

the first inlet is fluidly connected to the interior;

the second inlet is fluidly connected to the interior; and

the opening is fluidly connected to the interior.

4 . The fire pit of claim 3 , wherein the top further includes a flange extending in a third direction towards the interior.

5 . The fire pit of claim 1 , further comprising:

a first vane that extends along the first interior surface; and

a second vane that extends along the second interior surface,

wherein:

the first half-circular section includes a first side and a second side opposite the first side;

the first vane extends between the first side and the second side;

the second half-circular section includes a third side and a fourth side opposite the third side; and

the second vane extends between the third side and the fourth side.

6 . The fire pit of claim 5 , wherein:

the first vane includes a first upper surface and a first lower surface;

at the first side, the first lower surface is spaced apart from the first bottom surface;

at the second side, the first upper surface is aligned with the first top surface;

the second vane includes a second upper surface and a second lower surface;

at the third side, the second lower surface is spaced apart from the second bottom surface; and

at the fourth side, the second upper surface is aligned with the second top surface.

7 . The fire pit of claim 1 , wherein the opening is spaced apart from the first interior surface and the second interior surface.

8 . A device comprising:

a first half-circular sidewall including:

a first central axis,

a first interior surface,

a first top surface,

a first bottom surface,

a first side, and

a second side;

a second half-circular sidewall including:

a second top surface,

a second bottom surface,

a third side, and

a fourth side;

a first vane extending along the first interior surface;

a second vane extending along the second interior surface;

a bottom coupled to the first bottom surface and the second bottom surface;

a top coupled to the first top surface and the second top surface;

a first inlet formed between the bottom, the top, the first side, and the third side; and

a second inlet formed between the bottom, the top, the second side, and the fourth side.

9 . The device of claim 8 , further comprising:

a first damper configured to adjust an intake of first air through the first inlet; and

a second damper configured to adjust an intake of second air through the second inlet.

10 . The device of claim 9 , wherein:

the first damper is hingedly coupled to the first half-circular sidewall or the second half-circular sidewall; and

the second damper is hingedly coupled to the first half-circular sidewall or the second half-circular sidewall.

11 . The device of claim 9 , wherein:

the first damper is disposed between the bottom, the top, the first side, and the third side; and

the second damper is disposed between the bottom, the top, the second side, and the fourth side.

12 . The device of claim 8 , wherein the first inlet and the second inlet are opposed from one another.

13 . The device of claim 8 , wherein:
