The disclosure relates to devices and systems for outdoor heating. A stove device includes a fuel system for storing and controllably delivering fuel to a firepot inside a combustion chamber. A distance between the firepot and the fuel system is adjustable to change an amount of fuel for combustion and thereby control temperature of combustion.
Many individuals use outdoor heating in a variety of settings, such as dining out, social gatherings, sporting events, and the like. Typical outdoor heating devices use gas or propane. Gas or propane-fueled outdoor heating devices enable users to conveniently control temperature, for example by increasing and decreasing the amount of gas or propane delivered to the flame, but these approaches generally do not provide sufficient radiant heat to their surroundings. As a result, individuals are often not sufficiently warmed by gas and propane-fueled outdoor heating solutions. Alternative approaches include wood and wood pellet heating devices. These devices can, in certain circumstances, provide sufficient heat to their surroundings, but generally do not provide convenient control of temperature.
Accordingly, there is a need for improved devices and systems for outdoor heating which provide sufficient radiant heat to their surroundings, and which also provide convenient control of temperature. The present disclosure addresses this unmet need.
The disclosure relates to improved outdoor heating devices that utilize wood or wood pellets to provide sufficient radiant heat to their surroundings and which also utilize innovative mechanical features to enable individuals to conveniently adjust temperature of combustion. A stove device includes a firepot assembly, positioned in a combustion chamber of a housing of the stove device and configured for combustion of a fuel thereon, which is variably distanced from a fuel system configured to store the fuel and deliver the fuel to the firepot assembly for combustion. During use of the stove device, a distance between the firepot assembly and the fuel system can be adjusted to control temperature of combustion.
The housing can be comprised of a wheeled base affixed to a plurality of walls to form the combustion chamber and can include a roof with an exhaust assembly that extends upward therefrom as well as an ash tray disposed below the firepot assembly. The housing can be attached to a fuel system that comprises a hopper and a chute that can be used to gravity feed the fuel from the hopper through the chute and to the firepot assembly during combustion of the fuel. Heated air and gaseous combustion byproducts are directed upward through the exhaust assembly to a radiant cap at an upper portion of the elongated tube. Heat that reaches the radiant cap is radiated therefrom toward an area around the stove device to warm the area.
During combustion, the fuel can be held by the firepot assembly. As solid combustion byproducts accumulate, they can fall from the firepot assembly toward the ash tray or can accumulate on bars of a firepot of the firepot assembly. If the solid combustion byproducts build up at the firepot, this can impede the combustion reaction and can necessitate manual removal of the solid combustion byproducts by a sweep having brushes that are slidably disposed between bars of the firepot. A slide movement of the sweep moves brushes of the sweep to remove the solid combustion byproducts from the bars of the firepot which then fall from the firepot assembly toward the ash tray to facilitate combustion.
Temperature of combustion can be controlled by any of a plurality of mechanisms, including but not necessarily limited to a vertical or a horizontal adjustment of a handle member affixed to the firepot assembly. The handle member can be affixed to the firepot, the sweep, or a wedge. If the handle member is affixed to the firepot or the sweep, then a portion of the firepot can be moved vertically to adjust the distance between the firepot and the fuel system and secured at a desired position with a securement mechanism. If the handle member is affixed to the wedge, then the wedge can be moved horizontally to slide the wedge in and out from under a ridge of the firepot to vertically move a portion of the firepot to adjust the distance between the firepot and the fuel system which can be secured at a desired position with a securement mechanism.
An object of the present disclosure is to provide improved devices and systems for outdoor heating that provide sufficient and adjustable heat which can be made and used according to suitable manufacturing processes.

The housing 2 can be comprised of a wheeled base 10 which engages a surface thereunder either with a base of the wheeled base 10 or with a wheel assembly 13 attached to the base which can benefit moving the stove device 1 from one location to another. The wheeled base 10 can be affixed to a plurality of walls, such as front wall 5, right wall 6, back wall 7, and left wall 8. Walls of the plurality of walls can extend upward from the wheeled base 10 and connect to each other to form the combustion chamber. The housing 2 can comprise a roof 9 which connects to walls of the plurality of walls (such as front wall 5, right wall 6, back wall 7, and left wall 8) to define a volume of the combustion chamber. The roof 9 can be connected to the exhaust assembly 4 which extends upward from the roof 9 to expel gaseous combustion byproducts therefrom.
The exhaust assembly 4 can be comprised of a lower tube 30 connected to an upper tube 31 to form an elongated tube (30, 31) which can be hollow to allow heat and gaseous combustion byproducts to pass from the combustion chamber upward therethrough to a vent 32, a spark arrestor 33, and a radiant cap 34 disposed at an upper portion of the elongated tube (30, 21). The gaseous combustion byproducts can be expelled through the vent 32 and sparks can be stopped from exiting the elongated tube (30, 31) by the spark arrestor 33. Hot gases and radiation contact the radiant cap 34 which becomes heated and radiates heat to an area around the stove device 1.
The fuel system 3 can be comprised of a hopper 20 which can comprise a lid thereon configured to open and close to enable an individual to add (and potentially remove) fuel to and from an interior of the hopper 20. A hopper bottom 21 can be suitably angled to direct fuel from the interior of the hopper down a chute 22 of the fuel system 3 and into the combustion chamber and the firepot for combustion. The fuel system 3 can be assembled and attached to the housing 2 during assembly of the stove device 1.
The plurality of walls (such as front wall 5, right wall 6, back wall 7, and left wall 8) can comprise windowpanes 19 to enable individuals to view the combustion chamber from outside the stove device 1 before, during, and after use of the stove device 1.

As fuel, such as wood pellets, tumbles down the hopper bottom 21 and through the chute 22, it accumulates as a fuel pile within the firepot assembly and is ignited by an individual to start combustion or is continually burned as part of ongoing (i.e., previously ignited) combustion, and gaseous combustion byproducts exit the combustion chamber through the exhaust system 4. As the fuel burns the fuel pile becomes smaller and there becomes room for more fuel to enter the firepot assembly from the chute 22. The maximum amount of fuel in the fuel pile can be determined by the distance 60. If the distance 60 increases, then more fuel can fall into the fuel pile to increase the heat output from combustion. If the distance 60 decreases, then less fuel can fall into the fuel pile and the heat output from combustion decreases. The portion of the firepot assembly that is raised and lowered can be selected such that such raising and lowering impacts the volume of the fuel pile, for example, the portion raised and lowered can include a portion of the firepot assembly that is proximal to the fuel system 3 and the chute 22.
