Non-electric gravity feed pellet stove

A pellet stove for use in an interior of a structure, said pellet stove comprising:

• a stove enclosure having one or more walls defining an interior area of said pellet stove, said stove enclosure having one or more doors associated therewith to allow access to said interior area from outside said stove enclosure;
• a hopper assembly associated with the stove enclosure, said hopper assembly having a hopper with one or more hopper walls defining a pellet storage chamber for storing a quantity of pellet fuel therein, said hopper having a fuel discharge opening associated therewith for directing pellet fuel downward below said hopper, said hopper structured and arranged to gravity feed said pellet fuel from said pellet storage chamber through said fuel discharge opening;
• a core assembly disposed inside said interior area of said stove enclosure, said core assembly having a burn chamber housing positioned below said fuel discharge opening of said hopper, a primary burn channel connected in fluid flow communication with said burn chamber, and a flame chamber connected in fluid flow communication with said primary burn channel so as to pneumatically connect said flame chamber to said burn chamber;
• a hot plate associated with said flame chamber and a top wall of said stove enclosure, said hot plate positioned and configured to be heated by fire and heated air from said flame chamber and to define a heating surface on said top wall of said stove enclosure for cooking food and/or heating liquids thereon;
• a primary burn chamber assembly associated with said burn chamber housing in said interior area of said pellet stove for burning pellet fuel from said hopper, said primary burn chamber assembly having a primary burn chamber, a burn basket associated with said primary burn chamber and a fuel control mechanism operatively associated with said primary burn chamber and said burn basket, said burn basket sized and configured to receive the pellet fuel from said hopper, said fuel control mechanism and said burn basket being cooperatively structured and arranged to control the amount of pellet fuel received in said burn basket so as to control the amount of pellet fuel burned in said primary burn chamber assembly;
• and
• a venting system having an inlet tube associated with said stove enclosure to draw inlet air into said primary burn chamber assembly from outside the structure through an inlet pipe sealably connected to or integral with said inlet tube for combustion of the pellet fuel in said burn basket and discharges exhaust air from said flame chamber and out of said pellet stove through an exhaust pipe sealably connected to or integral with an exhaust tube associated with said stove enclosure,
• wherein said pellet stove is sealably configured such that after the pellet fuel is lit in said burn basket, the inlet air is drawn from said inlet pipe through said inlet tube to said burn basket to produce a fire therein that produces the fire, the heated air and the exhaust air that flows from the burning pellet fuel in said burn basket through said primary burn channel to said flame chamber so as to produce heat at said walls of said enclosure that heats the interior of the structure and to discharge the exhaust air out of said pellet stove through said exhaust tube and the exhaust pipe without drawing inlet air from the interior of the structure or discharging exhaust air into the interior of the structure.

A pellet stove for burning pellet fuel to produce heat for warming an interior of a structure and cooking, said pellet stove comprising:

• a stove enclosure having one or more walls defining an interior area of said pellet stove, said stove enclosure having one or more doors associated therewith to allow access to said interior area from outside said stove enclosure, each of said doors configured to be sealably closed;
• a hopper assembly associated with the stove enclosure, said hopper assembly having a hopper and a pellet chute below said hopper, said hopper having one or more hopper walls defining a pellet storage chamber for storing a quantity of pellet fuel therein and a shaped bottom section defining a fuel discharge opening for directing pellet fuel to said pellet chute positioned below said fuel discharge opening, said hopper and said pellet chute structured and arranged to gravity feed pellet fuel from said pellet storage chamber through said pellet chute;
• an adjustment mechanism associated with one of said hopper and said pellet chute to control the amount of pellet fuel discharged from said quantity of pellet fuel through said fuel discharge opening;
• a core assembly inside said interior area, said core assembly having a burn chamber housing positioned below said pellet chute, a flame chamber in spaced apart relation to said burn chamber housing and a primary burn channel interconnecting said burn chamber and said flame chamber in fluid flow communication so as to allow fire, heated air and exhaust air to flow from said burn chamber to said flame chamber;
• a glass panel associated with said stove enclosure at said flame chamber, said glass panel sized and configured to allow viewing of the fire in said flame chamber;
• a hot plate associated with said flame chamber and a top wall of said stove enclosure, said hot plate positioned and configured to be heated by the fire and the heated air in said flame chamber and to define a heating surface on said top wall of said stove enclosure for cooking food and/or heating liquids thereon;
• a primary burn chamber assembly disposed in said interior area of said pellet stove and associated with said burn chamber housing of said core assembly, said primary burn chamber assembly having a primary burn chamber, a burn basket supported by said primary burn chamber for receiving and burning the pellet fuel from said pellet chute, and a fuel control mechanism for controlling the amount of the pellet fuel received in said burn basket from said so as to control the amount of the pellet fuel burned in said primary burn chamber assembly;
• and
• a venting system having an inlet tube associated with said stove enclosure to draw inlet air into said primary burn chamber assembly from outside the structure through an inlet pipe sealably connected to or integral with said inlet tube for combustion of the pellet fuel in said burn basket and discharges exhaust air from said flame chamber and out of said pellet stove through an exhaust pipe sealably connected to or integral with an exhaust tube associated with said stove enclosure,
• wherein said pellet stove is sealably configured such that after the pellet fuel is lit in said burn basket, the inlet air is drawn from said inlet pipe and through said inlet tube to said burn basket to produce a fire therein that produces the fire, the heated air and the exhaust air that flows from the burning pellet fuel in said burn basket through said primary burn channel to said flame chamber so as to produce heat at said walls of said enclosure that heats the interior of the structure and to discharge the exhaust air out of said pellet stove through said exhaust tube and said exhaust pipe without drawing inlet air from the interior of the structure or discharging exhaust air into the interior of the structure.
