Definitions
- the present invention relates to a stove apparatus and more particularly to a portable stove apparatus with a basin member that directs heat to a cooking area and a plate member that distributes the heat evenly over the cooking area to effectively cook various food items.
- the prior art contains a variety of portable stoves designed for outdoor use, including simple camp stoves as well as more complex backyard gills. Many of these stoves deliver enough heat to a cooking area to cook different food items, but they suffer an important disadvantage—they fail to deliver the heat to the cooking area in an effective manner. Their cooking surfaces or areas include undesirable hot spots, typically in the middle portions of the areas, and equally undesirable cold spots, typically around the outer portions of the cooking areas.
- the portable stove apparatus of the present invention avoids the disadvantages of the prior art. It directs heat to a cooking area; and it distributes heat evenly over this cooking area. It performs these functions efficiently to conserve fuel and safely to prevent injury to a user.
- the stove apparatus of the present invention has a simple, light weight construction that minimizes the expense of fabrication and assembly and allows easy transport and use.
- a stove apparatus includes a housing and at least one basin member secured to the housing.
- the basin member forms a bottom pocket at one end and a top opening at another end.
- a burner extends into the pocket and provides heat that the basin member directs from the pocket to the top opening.
- a plate member that defines holes at predetermined positions of its body normally lies between the pocket and the top opening and distributes heat evenly across the top opening.
- a food supporting member normally disposed above the plate member proximate the top opening of the basin member supports food that the stove cooks.
- a perforated screen member normally disposed between the support member and the plate member further distributes the heat evenly across the top opening.
- the housing defines an open top. At least one top door pivotally mounted to the housing moves between a closed position in which it closes the open top of the housing and an open position in which it extends outwardly of the housing, substantially parallel to the open top of the housing. In the open position, the door serves as a shelf.

- the burner 33 is a side eject burner that receives air through an air intake 33 a and gas such as propane through a gas intake 33 b. This gas-air mixture moves through a passageway provided by a venturi tube 33 c and ejects it at a combustion end or burner head 33 d that lies in the basin member 34 (See FIG. 12).
- the air intake includes an adjustable collar 33 e that allows adjustment of the flow of air into the burner (See FIGS. 12 and 13).
- the basin member 34 includes a center, bottom portion 34 b which lies flat at its lowermost end and then extends upwardly and slightly outwardly.
- This portion 34 b defines a pocket 36 that receives the combustion end 33 d of the burner 33 .
- This combustion end 33 d defines a plurality of ports 33 f through which the burner 33 discharges the burning air-gas mixture. The burning mixture discharges into the pocket 36 .
- the portion 34 b directs the heat generated by the burner 33 towards the cooking area 35 ; and its flat lowermost end defines an opening 34 e through which the burner 33 extends into the pocket 36 .
- Sidewall portions 34 c connect the bottom portion 34 b with the top portions 34 a. These portions 34 c extend upwardly and outwardly from the bottom portion 34 b between a point A (the top of the pocket 36 ) and a point B, at which the top portions 34 a begin. The portions 34 c are a transition from the pocket 36 to the top of the basin member as defined by the top portions 34 a.

Abstract
Description
- 1. Field of the Invention
- The present invention relates to a stove apparatus and more particularly to a portable stove apparatus with a basin member that directs heat to a cooking area and a plate member that distributes the heat evenly over the cooking area to effectively cook various food items.
- 2. Description of the Prior Art
- The prior art contains a variety of portable stoves designed for outdoor use, including simple camp stoves as well as more complex backyard gills. Many of these stoves deliver enough heat to a cooking area to cook different food items, but they suffer an important disadvantage—they fail to deliver the heat to the cooking area in an effective manner. Their cooking surfaces or areas include undesirable hot spots, typically in the middle portions of the areas, and equally undesirable cold spots, typically around the outer portions of the cooking areas.
- The portable stove apparatus of the present invention avoids the disadvantages of the prior art. It directs heat to a cooking area; and it distributes heat evenly over this cooking area. It performs these functions efficiently to conserve fuel and safely to prevent injury to a user. The stove apparatus of the present invention has a simple, light weight construction that minimizes the expense of fabrication and assembly and allows easy transport and use.
- In accordance with one embodiment of the present invention, a stove apparatus includes a housing and at least one basin member secured to the housing. The basin member forms a bottom pocket at one end and a top opening at another end. A burner extends into the pocket and provides heat that the basin member directs from the pocket to the top opening.
- A plate member that defines holes at predetermined positions of its body normally lies between the pocket and the top opening and distributes heat evenly across the top opening. A food supporting member normally disposed above the plate member proximate the top opening of the basin member supports food that the stove cooks. A perforated screen member normally disposed between the support member and the plate member further distributes the heat evenly across the top opening.
- The housing defines an open top. At least one top door pivotally mounted to the housing moves between a closed position in which it closes the open top of the housing and an open position in which it extends outwardly of the housing, substantially parallel to the open top of the housing. In the open position, the door serves as a shelf.
- The basin member lies in the housing, spaced from the walls of the housing. Thus, the basin member and the housing cooperate to form an air pocket between them. This air pocket minimizes heat transfer between the basin member and housing of the apparatus and helps maintain the housing at a cool and safe temperature.

- Turning now to the drawings and referring specifically to FIGS.1-9 and 15-16, the
portable stove apparatus 20 of the present invention includes a generallyrectangular housing 21 with afront wall 21 a, a back wall 21 b, andsidewalls housing 21 is a sheet metal structure (or a structure made of any other suitable material of high strength and rigidity) as are the other components described below. Thehousing 21 is a sleeve-like structure with an open top and an open bottom. - Two
top doors housing 21. They lie pivotally mounted to top edge portions of thesidewalls housing 21 as shown in FIGS. 1 and 3. Each of thetop doors top doors stove 20 and in the closed position during storage or transport of the stove. - In the open position, the
top doors housing 21 as shown in FIG. 3. Thehousing 21 also stops each top door from moving beyond the closed position. In the closed position of thedoors lock bottoms 24 disposed on thehousing 21 extend into opening 25 in thetop doors 22 and 23 (See FIG. 2). Thehousing 21 includes fourlock bottoms 24 which cooperate with the four corner portions that definesopenings 25 of thetop doors top doors - A
bottom door 26 normally closes the open bottom of the housing 21 (See FIG. 4). Like thetop doors housing 21. Two spring loaded latching mechanisms 27 (See FIGS. 5-7) of thehousing 21 cooperate withopenings 28 in thebottom door 26 to releasably secure thebottom door 26 to thehousing 21 in the closed position shown in FIG. 8. - Each
latching mechanism 27 includes atop segment 27 a, a bottom segment 27 b pivotally connected to the top segment, and acompression spring 27 c. Thislatching mechanism 27 lies rotatably mounted to thehousing 21 so that one may place it in the position shown in FIG. 5 (where thetop segment 27 a may extend through one of the openings 28) and then rotate it 90° to the latching position shown in FIGS. 6 and 7. In this latching position, one may further move thetop segment 27 a into face-to-face relation with thebottom door 26. - In its closed position, the
bottom door 26 conceals fourlegs 29 of thestove apparatus 20 if they lie in the folded or retracted position. (The fourlegs 29 lie pivotally secured to thehousing 21 as at 30 (See FIGS. 15 and 16); and they support thehousing 21 a predetermined distance above a supporting surface, FIG. 1.) With thebottom door 26 in this closed position and with thetop doors stove apparatus 20 of the present invention using ahandle 31 fixedly secured to the housing 21 (as shown in FIGS. 8 and 9). - In its closed position, the
bottom door 26 also serves as a stop for thelegs 29 when the legs lie in the extended position. As shown in FIG. 16, anedge portion 26 a of thebottom door 26 and a bottom edge portion of a sidewall of thehousing 21 secure aleg 26 between each other and lock it in the extended position. (Thebottom door 26 also defines openings 26 b-f that allow air to circulate through thehousing 21 so that the air may keep thehousing 21 cool and facilitate combustion of the fuel used by thestove 20. Similarly, thehousing 21 includes openings 21 e in itsfront wall 21 a and openings 21 f and 21 g in its back wall 21 b for the same purpose.) - The
housing 21 supports twoburner assemblies 32 that provide heat for thestove apparatus 20 as described below (See FIGS. 10-15). Eachburner assembly 32 includes aburner 33 for burning a gas and air mixture to provide heat and abasin member 34 for directing the heat to acooking area 35 generally defined by thetop portions 34 a of thebasin member 34. (Thecooking areas 35 of the burner assemblies lie in substantially the same plane; and this plane lies proximate the top openings of thehousing 21.) - The
burner 33 is a side eject burner that receives air through anair intake 33 a and gas such as propane through a gas intake 33 b. This gas-air mixture moves through a passageway provided by a venturi tube 33 c and ejects it at a combustion end orburner head 33 d that lies in the basin member 34 (See FIG. 12). The air intake includes an adjustable collar 33 e that allows adjustment of the flow of air into the burner (See FIGS. 12 and 13). - The
basin member 34 includes a center,bottom portion 34 b which lies flat at its lowermost end and then extends upwardly and slightly outwardly. Thisportion 34 b defines a pocket 36 that receives thecombustion end 33 d of theburner 33. (Thiscombustion end 33 d defines a plurality of ports 33 f through which theburner 33 discharges the burning air-gas mixture. The burning mixture discharges into the pocket 36.) Also, theportion 34 b directs the heat generated by theburner 33 towards thecooking area 35; and its flat lowermost end defines an opening 34 e through which theburner 33 extends into the pocket 36. - Sidewall portions34 c connect the
bottom portion 34 b with thetop portions 34 a. These portions 34 c extend upwardly and outwardly from thebottom portion 34 b between a point A (the top of the pocket 36) and a point B, at which thetop portions 34 a begin. The portions 34 c are a transition from the pocket 36 to the top of the basin member as defined by thetop portions 34 a. Thetop portions 34 a extend upwardly from the point B to the top distal end of thebasin member 34. - Various plate-
like members burner 33 or support food or pots and pans at thecooking area 35. (Baffle plates 41 (See FIG. 17) also shield thecooking area 35 from the wind.) The deflectingplate 37 lies below thebasin member 34 fixedly secured (e.g., riveted as at 37 r, welded, etc.) to it. This deflecting plate deflects the heat upwardly towards thecooking area 35; and it definesopenings 37 a which allow air to move into a space C between it and thebasin member 34 to cool that space. - The
cooking plate 38 is a separate, removable component disposed on top of thebasin member 34. One example of such a cooking plate is the relatively open grating 38 a shown in FIG. 10 and designed to hold pots and pans. Another example is the more closed grating 38 b shown in FIG. 10 and designed to hold meats and other such food items. And, yet another example is the griddle 38 c shown in FIG. 18 for cooking pancakes and similar foods. - The other two
components stove apparatus 20. When heating a pot placed in the center of thecooking area 35, one need not use theplate member 39 or thescreen member 40. In this way, theburner 33 heats mainly the center of thecooking area 35. When heating meats and similar foods, theplate member 39 and thescreen member 40 distribute the heat evenly across thecooking area 35, and thescreen member 40 collects any droppings from thecooking area 35. - The
plate member 39 has a plurality of holes that evenly distribute the heat of theburner 33 as it rises to thecooking area 35. A first set of holes 39 a having a diameter Da lie around the center CP of theplate member 39 at a radius of Ra from the center. A second set of holes 39 b having a diameter Db lie at a radius Rb. A third set 39 c with holes of two different diameters having magnitudes Dc1 and Dc2 lie at a radius of Rc; and afourth set 39 d having a diameter Dd lie at a radius of Rd. - As shown in FIG. 11, the first set of holes39 a has a greater diameter than that of the second set of holes 39 b. The
burner 33 discharges the burning air and gas mixture between these two sets of holes 39 a and 39 b; and the heat generated by theburner 33 tends to move radially outwardly of the center of thebasin member 34. Thus, the size of the first set of holes 39 a is greater than the size of the second set of holes 39 b to prevent a “cold spot” from developing in the middle of thebasin member 34 and accordingly in the middle of thecooking area 35. The third set of holes are larger than the first or second set of holes; and the third set includes smaller and larger holes. The fourth set of holes are the same size as the larger of the holes in the third set. - By way of a specific example, a
plate member 39 for abasin 34, having a cooking area 35 (bounded by thetop portions 34 a of the basin member 34) of 12⅛ inches by 12⅛ inches and a pocket 36 having a diameter of 7 inches at the top and 5½ inches at the bottom and a height of 1⅛ inches, has the following values for each of the parameters outlined above.Ra = 1.5 inches* Da = 0.375 inches Rb = 3.0 inches Db = 0.25 inches Rc = 4.5 inches Dc1 = 0.75 inches Dc2 = 1.00 inches Rd = 6.5 inches Dd = 1.00 inches - The
plate member 39 is an 11 gauge steel plate; and theburner 33 has a diameter of 4 inches at the ports. The total height of the basin member 34 (from the bottom surface of theportion 34 b to the top ofportions 34 a) is 2.875 inches. - In another example, the
cooking area 35 is 9¾×9¾ inches; the pocket 36 has a diameter of 7 inches at the top and 5½ inches at the bottom and a height of 1⅛ inches; and the other parameters shown above have the following values:Ra = 1.25 inches* Da = 0.307 inches Rb = 2.50 inches Db = 0.200 inches Rc = 3.75 inches Dc1 = 0.625 inches Dc2 = 0.625 inches Rd = 5.30 inches Dd = 0.830 inches - The plate member is a 14 gauge steel plate; and the
burner 33 has a diameter of 4 inches at the ports. The total height of thebasin member 34 is 2.875 inches. - In yet another example, the
cooking area 35 is 13¾×13¾ inches; the pocket 36 has a diameter of 7 inches at its top and 5½ inches at its bottom with a height of 1⅛ inches; and the other parameters have the following values:Ra = 1.50 inches* Da = 0.375 inches Rb = 3.00 inches Db = 0.250 inches Rc = 5.50 inches Dc1 = 0.750 inches Dc2 = 0.750 inches Rd = 7.50 inches Dd = 1.000 inches - The
plate member 39 is an 11 gauge steel plate; and theburner 33 has a diameter of 4 inches at the ports. The total height of thebasin member 34 is 2.875 inches. - The
plate member 39 also definesdimple portions 39 e disposed at predetermined positions over the face of theplate member 39. All of thesedimple portions 39 e protrude outwardly of the face of theplate member 39 substantially the same distance. They support thescreen member 40 to provide apocket 42 between theplate member 39 and thescreen member 40. Thispocket 42 further facilitates heat distribution (See FIG. 12). Thescreen member 40 is a flat plate-like screen with evenly spaced rows of evenly spaced perforation. As stated above, thescreen member 40 further distributes the heat as it moves upwardly in thebasin member 34 and collects droppings from thecooking area 35. - Two
beams housing 21 and secured to opposite ends of the housing support the burner assemblies 32 (See FIGS. 10 and 20-21). Thesebeams back walls basin members 34 of the twoburner assemblies 32 lie between thebeams beam 44 hasopenings 44 a andopenings 44 b that further facilitate cooling of the space around thebasin member 34. - Arranged in this manner, these components define pockets or
spaces housing 21 and thebasin members 34 and a space 49 between thehousing 21 and the twobasin members 34. These spaces insulate thehousing 21 from the heat generated by theburner assemblies 32, making thehousing 21 safe for touching. - Although the embodiment described above includes two
burner assemblies 32, thestove apparatus 20 of the present invention may have only one burner assembly, or it may have more than the two shown. In addition, an open frame may replace thehousing 21; and eachbasin member 34 may have a rounded configuration defininground cooking areas 35 rather than rectangular areas provided by the basin members shown. - While the above description and the drawings disclose and illustrate one embodiment, one should understand, of course, that the invention is not limited to this embodiment. Those skilled in the art to which the invention pertains may make other modifications and other embodiments employing the principles of this invention, particularly upon considering the foregoing teachings. Therefore, by the appended claims, the applicants intend to cover any modifications and other embodiments as incorporate those features which constitute the essential features of this invention.
