Heating and cooking system
View Patent ↗Systems and methods of use pertaining to a rocket-type heating and cooking system feature three distinct cooking surfaces designed for simultaneous use and may be dismantled and transported for use in a variety of environments, including use as a heating and cooking device in the home as a fireplace insert, use outdoors in a hiking or camping setting, or use in a developing-world application as a third-world outdoor or indoor kitchen. The heating and cooking system features a combustion chamber and exhaust chimney having optimized dimensions to achieve maximum combustion efficiency, which translates to increased heating and cooking capacities as well as reduced smoke exhaustion. Other embodiments are also disclosed.
1. A heating and cooking system, comprising:
a combustion chamber bounded by top and bottom surfaces, an air intake, and an air exhaust, the combustion chamber configured to contain an amount of natural fuel; and
a vertical chimney in fluid communication with the air exhaust of the combustion chamber, wherein:
the top surface bounding the combustion chamber is configured to transfer heat to a first cooking surface;
the bottom surface bounding the combustion chamber is configured to transfer heat to a second cooking surface; and
the vertical chimney is configured to transfer heat to a third cooking surface, wherein the combustion chamber is physically isolated from the first and the second cooking surfaces via a sealed configuration that prevents a flow of fluids and a flow of solids between the combustion chamber and both of the first and the second cooking surfaces.
2. The heating and cooking system of claim 1 , wherein the combustion chamber is horizontal.
3. The heating and cooking system of claim 1 , wherein:
the first cooking surface comprises a stovetop;
the second cooking surface comprises an oven drawer, the oven drawer including an open-topped compartment having a bottom wall and four side walls, the oven drawer configured to slide horizontally into and out of the heating and cooking system beneath the bottom surface of the combustion chamber; and
the third cooking surface comprises a barbecue grill.
4. The heating and cooking system of claim 1 , wherein the natural fuel comprises at least one of wood, dried grass, and pine cones.
5. The heating and cooking system of claim 1 , wherein the air intake of the combustion chamber has a width-to-height aspect ratio of 2:1.
6. The heating and cooking system of claim 1 , wherein:
the vertical chimney has a first length;
the combustion chamber has a second length; and
the first length and said second length have a length-to-length ratio of 4:3.
7. The heating and cooking system of claim 1 , wherein the system is portable.
8. The heating and cooking system of claim 7 , wherein the vertical chimney is removably attached to the combustion chamber.
9. The heating and cooking system of claim 1 , wherein the combustion chamber and the vertical chimney are formed of steel or aluminum.
10. A portable, high-efficiency system for heating and cooking, comprising:
an enclosed combustion chamber, the enclosed combustion chamber having a first end forming an air intake and a second end forming an air outlet; and
a vertical exhaust, the vertical exhaust having a first end in fluid communication with an ambient environment and a second end in fluid communication with the air outlet of the enclosed combustion chamber, wherein:
the air intake of the enclosed combustion chamber has a width-to-height aspect ratio of 2:1;
a length of the vertical exhaust and a length of the enclosed combustion chamber have a length-to-length ratio of 4:3;
a top surface bounding the combustion chamber transfers heat to a first cooking surface; and
a bottom surface bounding the combustion chamber transfers heat to a second cooking surface that is physically isolated from the combustion chamber by a sealed configuration that prevents a flow of fluids and a flow of solids between the combustion chamber and the second cooking surface.
11. The portable, high-efficiency system of claim 10 , wherein:
the vertical exhaust is configured to transfer heat to at least a third cooking surface.
12. The portable, high-efficiency system of claim 11 , wherein:
the first cooking surface comprises a stovetop;
the second cooking surface comprises an oven drawer, the oven drawer including an open-topped compartment having a bottom wall and four side walls, the oven drawer configured to slide horizontally into and out of the system beneath the bottom surface of the combustion chamber; and
the third cooking surface comprises a barbecue grill.
13. The portable, high-efficiency system of claim 10 , further comprising a draft damper, the draft damper configured for incremental insertion into the air intake to control airflow into the portable system.
14. The portable, high-efficiency system of claim 10 , further comprising a detachable attachment point between the vertical exhaust and the enclosed combustion chamber.
15. The portable, high-efficiency system of claim 10 , wherein the system is formed of steel or aluminum.
16. A multi-functional rocket stove, comprising:
a combustion tube forming a combustion chamber having an air inlet therein, the combustion tube coupled with a vertical exhaust such that air flowing into the system via the air inlet of the combustion chamber exits the system via the vertical exhaust, wherein:
a width-to-height ratio of the air inlet and a length-to-length ratio of the vertical exhaust to the combustion chamber are optimized to achieve maximum fuel efficiency; and
the combustion chamber and the vertical exhaust simultaneously transfer heat to at least three cooking surfaces including:
a first cooking surface at a top surface bounding the combustion chamber;
a second cooking surface adjacent a bottom surface bounding the combustion chamber; and
a third cooking surface in fluid communication with the vertical exhaust, wherein the combustion chamber is physically isolated from the first and the second cooking surfaces via a sealed configuration that prevents a flow of fluids and a flow of solids between the combustion chamber and both of the first and the second cooking surfaces.
17. The multi-functional rocket stove of claim 16 , wherein the width-to-height ratio and the length-to-length ratio are optimized for smoke reduction.
18. The multi-functional rocket stove of claim 17 , wherein:
the width-to-height ratio of the air inlet is 2:1; and
length-to-length ratio of the vertical exhaust to the combustion chamber is 4:3.
19. The multi-functional rocket stove of claim 16 , wherein:
the first cooking surface comprises a stovetop;
the second cooking surface comprises an oven drawer, the oven drawer including a removeable open-topped compartment configured to slide horizontally beneath the bottom surface of the combustion chamber; and
the third cooking surface comprises a barbecue grill.
20. The multi-functional rocket stove of claim 16 , further comprising a draft damper configured for incremental insertion into the air intake to control the air flowing into the system.
