Detailed Description

FIG. 1A is a diagram illustrating a nested stove 100. The nested stove 100 includes an outer stove 110 and an inner stove 120. In some embodiments, the outer cooktop 110 can be referred to as an outer cooktop portion, and the inner cooktop 120 can be referred to as an inner cooktop portion. The inner stove 120 may have an outer surface 121 and the outer stove 110 may have an inner surface 122. As illustrated, the inner stove 120 is disposed within at least a portion of the outer stove 110. In some embodiments, the inner stove 120 and the outer stove 110 may be part of a kit. In some embodiments, the nested stove described herein may not include a hinge.

As shown, the inner cooktop 120 may have a top opening 122 and may have a bottom opening 123. The outer stove 110 may have a top opening 112 and may have a bottom opening 113. The inner stove 120 can be inserted into the outer stove 110 via the top opening 112 or via the bottom opening 113. The inner stove 120 may be disposed within a chamber (e.g., combustion chamber) or cavity defined by the outer stove 110. The top opening 122 and the bottom opening 123 of the inner stove 120 are located at opposite ends of the inner stove 120. The top opening 122 and the bottom opening 123 of the outer stove 120 are located at opposite ends of the outer stove 120.

As shown in fig. 1A, nested stove 100 may have a combustion chamber 160 (which may also be referred to as a burn chamber). In this embodiment, the combustion chamber 160 is disposed within the inner stove 120 and within the channel 130 (e.g., concentrically within the channel 130). Various fuels may be combusted within the combustion chamber 160, such as solid fuels, liquid fuels, and so forth. In some embodiments, wood fuel, gaseous fuel, or the like may be combusted within the combustion chamber 160.

Fig. 1B illustrates an outer stove 110 and fig. 1C illustrates an inner stove 120. The inner range 120 may have a combustion chamber 165 and may be used as a separate range from the outer range 110. The outer cooking range 110 may have a combustion chamber 164 and may be used as a separate cooking range from the inner cooking range 120.

Although not shown in fig. 1A-1C, in some embodiments, the inner cooktop 120 may have one or more openings (also may be referred to as holes) (e.g., combustion openings) through which combustion air may flow and/or one or more openings (e.g., ventilation openings) through which exhaust gases may be expelled after combustion of the fuel. In some embodiments, the openings (or pattern of openings) in the inner cooktop 120 and the openings (or pattern of openings) in the outer cooktop 110 may be the same or may correspond. In some embodiments, the openings (or pattern of openings) in the inner cooktop 120 may be different from the openings (or pattern of openings) in the outer cooktop 110.

As shown in fig. 1A, an outer surface 121 of the inner stove 120 and an inner surface 111 of the outer stove 110 may define a channel 130. The passage 130 may be between the inner stove 120 and the outer stove 110.

As shown in fig. 1A, the inner stove 120 and the outer stove 110 are each defined by a single wall. For example, the outer surface 121 of the inner cooktop 120 is defined by a single wall (e.g., a circular wall) or a wall plate. Similarly, the inner surface 111 of the outer stove 120 may be defined by a single wall (e.g., a circular wall) or a wall plate.

In some implementations, the height (e.g., vertical height or distance) (e.g., height H1, height H2) and/or the width W1 of the channel 130 (e.g., the width between the outer surface 121 of the inner stove 120 and the inner surface 111 of the outer stove 110) may depend on other dimensions, such as the height of the outer stove 110 and/or the inner stove 120. In some embodiments, if the nested stove 100 has a relatively tall outer stove 110, the width of the channel 130 may be increased to facilitate air flow within the channel 130. In some embodiments, if the nested stove 100 has a relatively tall inner stove 110, the width of the channel 130 may be increased to facilitate air flow within the channel 130. In some implementations, if the width of the channel 130 is increased too much, convection (e.g., air flow as shown in fig. 6 and 7B) may be reduced by the channel 130.

In some embodiments, the height H1 of inner cooktop 120 and/or H2 of outer cooktop 110 may be greater (e.g., significantly greater) than the width W1 of channel 130. In some implementations, the height H1 and/or the height H2 can be at least 2 times (e.g., 2.5 times, 3 times, 4 times, 5 times, 10 times) the width W1 of the channel 130.

In some embodiments, the height H1 of the inner cooktop 120 can be greater (e.g., at least 2 times greater) than the width (e.g., diameter) (not labeled) of the top opening 122 and/or the bottom opening 123. In some embodiments, the height H2 of the outer cooktop 120 can be greater (e.g., at least 2 times greater) than the width (e.g., diameter) (not labeled) of the top opening 122 and/or the bottom opening 123. The W1 of the tunnel may be smaller than the width (e.g., diameter) of the inner stove 120 and/or the width (e.g., diameter) of the outer stove 110.

In some embodiments, rather than being centrally located within the nested stove 100, the inner stove 120 may be offset from the center of the outer stove 120. Thus, in these embodiments, the channel 130 may have a first width on a first side of the nested stove 100 that is different from a second width on a second side of the nested stove 100.

As shown in fig. 1A, the height H1 of the inner stove 120 is the same as the height H2 of the outer stove 110. In some embodiments, height H1 of inner cooktop 120 (or a portion thereof) can be different than height H2 of outer cooktop 110 (or a portion thereof). For example, the height H1 of the inner stove 120 (or a portion thereof) may be less than the height H2 of the outer stove 110 (or a portion thereof).

Fig. 2A illustrates an assembly of 2 cooktops (outer cooktop 210 and inner cooktop 220) that can be combined into a nested stove 200 (e.g., a wood gas stove). In some embodiments, only a portion of the nested stove 200 is described, however, similar or mirror portions may have the same functionality.

For example, a nested configuration of the stove (nested stove 200) is shown in fig. 5, 8A, 8B and 9. As shown in fig. 2A, portions of the outer stove 210 and the inner stove 220 are shown as discrete flat portions that can be assembled into individual stoves (210, 220) and nested stoves 200. Thus, the outer stove 210, the inner stove 220, and/or the nested stove 200 may be folded or stacked flat on top of each other.

The outer stove 210 and the inner stove 220 are shown in fig. 2B as separate stoves (in an assembled state). Specifically, fig. 2B illustrates a top view of the outer and

inner cooktops

210, 220 in an assembled state. Outer stove 210 and inner stove 220 are illustrated as two separate independent stoves, which may be fuel (e.g., stick-burning) stoves.

Fig. 2A illustrates that the outer stove 210 includes wall plates 215A-215D (which may be collectively referred to as wall plates 215). In this embodiment, the outer stove 210 comprises 4 wall plates. In this embodiment, each of the wall panels included in the outer cooktop 210 are the same (e.g., have the same dimensions). Specifically, each of the wall panels 215 has the same hole (or opening) pattern. In this implementation, several columns (e.g., 2 columns) of parallel holes 217 are vertically aligned (vertically when in an assembled configuration as shown in fig. 2B) along each of the wall plates 215. In some embodiments, the holes 217 may not be aligned vertically, but may have different patterns.

Similar to the outer cooktop 210, the inner cooktop 220 includes wall plates 225A-225D (which may be collectively referred to as wall plates 225). In this embodiment, the inner cooktop 220 comprises four (4) wall panels. In this embodiment, each of the wall plates 220 included in the outer stove 210 is the same (e.g., has the same dimensions). Specifically, each of the wall panels 225 has the same hole pattern. In this embodiment, a series of holes 227 are horizontally aligned (horizontally when in an assembled configuration as shown in fig. 2B) along each of the wall plates 225. In some implementations, the apertures 227 may not be horizontally aligned and may have different patterns. Aperture 227 is larger (e.g., larger area) than aperture 217. In some embodiments, holes 217 may be used for pins 212, and holes 227 may be used for ventilation or combustion gas flow.

Since each of the wall panels 215, 225 belonging to the

cooktops

210, 220, respectively, is identical (e.g., has the same dimensions), each of the cooktops defines a square profile (e.g., shape, perimeter) by virtue of the wall panels being oriented orthogonally (in plan view). For example, each of the wall panels 215 of the outer stove 210 are identical. Thus, the outer stove 210 defines a square profile (in plan view) when assembled, since each of the wall panels 215 has the same length.

In some embodiments, one or more of the wall plates 215 may be different from the others of the wall plates 215 (e.g., different dimensions, different heights, thicknesses, widths, etc.). In some embodiments, one or more of the wall panels 225 may be different from the others of the wall panels 225 (e.g., different dimensions, different heights, thicknesses, widths, etc.).

In some embodiments, one or more of the wall plates 215, 225 may have a different length than the other of the wall plates 215, 225. For example, the first pair of wall plates 215 may have a different shape than the second pair of wall plates 215. Thus, when assembled, the outer cooking range 210 may have a rectangular profile in profile. In some embodiments, one or more of the

cooktops

210, 220 can have a different profile, such as a trapezoidal profile or the like.

In some implementations, one or more of the

stoves

210, 220 may include more than 4 or less than 4 wall plates. More details regarding cooktops having more than 4 walls or less than 4 walls are described below.

In this embodiment, each of the wall panels 215, 225 includes at least one tab and slot. Specifically, in this embodiment, each of the walls 215, 225 includes four tabs and four slots. Each of the tabs is associated with a slot. The tabs and slots of the wall panels 215, 225 may be used to detachably couple the wall panels 215, 225 to one another so that they may be assembled to form the respective outer and

inner cooktops

210, 220. The tabs of the outer stove 210 and the inner stove 220 may be collectively referred to as

tabs

213 and 223, respectively.

For example, wall 225D includes tab 223D-1 and slot 224D-1. Slot 224D-1 is associated with tab 223D-1. As another example, wall 225C includes tab 223C-2 and slot 224C-2. Tab 223D-1 and slot 224D-1 (of wall panel 225D) and tab 223C-2 and slot 224C-2 (of wall panel 225C) may be used to couple wall panel 225D to (at least in part) wall panel 225C. Specifically, slot 224D-1 may be engaged with (e.g., slidably inserted into) slot 224C-2. Accordingly, tab 223C-2 may engage tab 223D-1 (and may contact a main portion (an example of which is described below) of wall panel 225D). Similarly, tab 223D-1 may engage tab 223C-2 (and may contact a major portion of wall panel 225C). The engagement of tab 223D-1 (of wall plate 225D) with slot 224D-1 and the engagement of tab 223C-2 (of wall plate 225C) with slot 224C-2 in the assembled configuration as interior stove 220 is shown in FIG. 2B.

In some embodiments, the slots may be referred to as being included in the tabs. For example, as shown in FIG. 2A, slot 224D-1 is disposed between tab 223D-1 and main portion 229D (illustrated in phantom) of wall panel 225D. In some embodiments, tab 223D-1 can be said to extend from main portion 229D of wall panel 225D. Tab 223D-1 is also aligned in the plane of main portion 229D of the wall panel. The main portion 229D of the wall plate is disposed within the slot. In some embodiments, one or more of the tabs of web 225D may be aligned in a plane that is different from (e.g., at an obtuse angle relative to) the plane in which main portion 229D of the web is aligned.

As shown in FIG. 2A, notch 226D is disposed between tab 223D-2 and tab 223D-1. This will allow a portion of another of the wall plates (e.g., wall plate 225C) to be coupled to wall plate 225D. For example, tab 223C-2 may be removably coupled to tab 223D-1 by inserting tab 223C-2 into slot 226D. Wall plate 225D is movable (e.g., slidably movable) in a direction opposite wall plate 225C such that slot 224D-1 can engage slot 224C-2.

In some embodiments, the slot has a length that is less than a length of the tab. For example, slot 224D-1 has a length that is less than the length of tab 223D-1. In some embodiments, the slot may have a length that is half the length of the tab. In some embodiments, the slot may have a length that is greater than or less than half the length of the tab.

In some embodiments, the slot can have a width that is about equal to (or slightly greater than) the thickness of the wall plate. The width may be defined such that the tab and slot of the first panel may engage the tab and slot of the second panel. For example, slot 224D-1 can have a width approximately equal to the width of wall plate 225C such that a portion of wall plate 225C can slidably move into slot 224D-1. In some embodiments, the slot in the first wall plate can have a relatively wide width such that the second wall plate can move at various angles (e.g., acute, obtuse) relative to the first wall plate. In these implementations, more than four walls (e.g., 6 walls s) can be coupled to define a stove.

As shown in fig. 2A (and fig. 2B), each of the

stoves

210, 220 includes a

combustion chamber base

218, 228, respectively. In this embodiment, the

combustor base

218, 228 is made of a mesh material. In some embodiments, one or more of the

combustor bases

218, 228 may be made of a solid metallic material and may have openings (or holes) therethrough.

As shown in fig. 2A, one or more of the pins 212 may be disposed in one or more of the holes included in the wall plates 215, 225. In some embodiments, at least one pair of pins 212 may be used to support one or more of the

combustor bases

218, 228. For example, as shown in fig. 2B, a pair of pins 212 may be inserted into the holes 217 to support a combustor base 218 within the outer stove 210. As shown in fig. 2B, the pair of pins can be placed within holes 217 along

wall plates

225B and 225D at various heights. The pair of pins may also be placed in holes 217 in

wall plates

225A and 225C (or in holes in any combination of wall plates). Similarly, although not shown in fig. 2B, a pair of pins 212 may be inserted into one or more holes (e.g., a pair of holes in opposing walls) (not shown) to support the combustor base 228 within the inner stove 220. Although not shown, in some implementations, a vertical hole (similar to vertical hole 217) may be included in one or more of the wall plates 225 of the interior stove 220.

In some embodiments, fuel may be placed on one or more of the combustion chamber bases 218, 228 during operation of the cooktops 210, 220 (e.g., assembled as shown in fig. 2B). In some embodiments, one or more of the combustion chamber bases 218, 228 may be placed within the

respective cooktop

210, 220 to allow air flow. For example, during operation of the outer stove 210, the combustion chamber base 218 may be spaced from the bottom of the outer stove 210 to allow combustion air to flow under the fuel disposed on the combustion chamber base 218. The outer stove 210 may define a combustion chamber 264 and the inner stove 220 may define a combustion chamber 265.

As shown in fig. 2A, a baffle 250 may be associated with the outer stove 210 and/or the inner stove 220. In some embodiments, the baffle 250 may be used when the outer stove 210 and the inner stove 220 are assembled as the nested stove 200. The baffle 250 may be used to direct (e.g., divert) the combustion air and/or ventilation gas. Further details regarding the baffle 250 are described in connection with at least fig. 7A and 7B. In some embodiments, the outer cooktop 210, the inner cooktop 220, and the baffle 250 can be included in a kit.

As shown in fig. 2B, two tabs and two slots are engaged on each corner of each of the

cooktops

210, 220. In some implementations, less than two tabs and less than two slots can engage on one or more of the corners of one or more of the

cooktops

210, 220, and/or more than two tabs and more than two slots can engage on one or more of the corners of one or more of the

cooktops

210, 220.

As shown in fig. 2B, spaces S1, S2 (which may also be referred to as gaps) are provided between at least one of the walls and the bottom of the

cooktops

210, 220, respectively. In other words, the first pair of walls of each of the

cooktops

210, 220 is vertically offset from the second pair of walls. In some implementations, the spaces S1, S2 may be defined to allow a flow of gas (e.g., combustion air) into the

combustion chambers

264, 265 of the

respective stoves

210, 220. Spaces S3 (corresponding to S1), S4 (corresponding to S2) are included at a top portion of each of the

cooktops

210, 220. In some implementations, the magnitude of the spaces S1, S2 (and S3, S4) may be defined by the length of the slots and/or tabs of the wall panels. In some implementations, S1 (and/or S3) may be greater than S2 (and/or S4). In some implementations, S1 (and/or S3) may be equal to or less than S2 (and/or S4).

In some embodiments, holes 227 in inner cooktop 220 may allow air flow for combustion purposes. As shown in fig. 2B, the holes 227 are oriented along a bottom portion of each of the

wall plates

225B, 225D and along a top portion of each of the

wall plates

225A, 225C. In some embodiments, apertures (e.g., horizontal apertures) may be included in one or more of the wall panels 225A-225D such that airflow may be generated in different ways. For example, horizontal holes may be included in both the top and bottom portions of the wall plate. Although not included in this embodiment, in some embodiments, horizontal holes (similar to horizontal hole 227) may be included in one or more of the wall plates 215 in the outer stove 210 and may allow air flow for combustion purposes.

Fig. 3 illustrates the outer stove 210 and the inner stove 220 shown in fig. 2B, each in an assembled configuration and in use. As shown in fig. 3, the inner stove 220 has a height T1 that is less than the height T2 of the outer stove 210. The inner cooktop 220 has a width P1 that is less than the width P2 of the outer cooktop 210. The height and/or width of the

stoves

210, 220 may be configured such that the inner stove 220 may be inserted into and disposed within the outer stove 210. The height and/or width of the

stoves

210, 220 may be configured to support cooking appliances of different sizes, as shown in fig. 3.

Fig. 4A and 4B illustrate top views of an inner stove 220 inserted (e.g., moved, slidably moved) into an outer stove 210. The inner stove 220 is further advanced into the combustion chamber 264 of the outer stove 210 in fig. 4B. Fig. 5 illustrates an inner stove 220 disposed (e.g., fully disposed) within an outer stove 210. The

stoves

210, 220 are shown aligned. The inner cooktop 220 may be concentrically disposed within the outer cooktop 210 in a top view.

As shown in fig. 4A, 4B, and 5, the tabs 223 of the inner cooktop 220 help to at least partially define at least one channel 230 (e.g., airflow channel, four airflow channels). Passages, which may be collectively referred to as passages 230 (for example, individual passages may be 230A, 230B, 230C), are defined between an outer surface of a wall plate 225 of the inner stove 220 and an inner surface of a wall plate 215 of the outer stove 210. The wall plates may be detachably coupled such that the tab 223 of the wall plate 225 of the inner stove 220 is in contact with the main portion of the wall plate 215 of the outer stove 210. For example, tab 223C-1 of wall panel 225C (extending from wall panel 225C) may be in contact with a major portion of wall panel 215D. In some embodiments, one or more of the tabs 223 of the inner stove 220 may not contact one or more of the interior side walls (main portions) of the wall panel 215 of the outer stove 210.

In some embodiments, the width of the channel 230 is defined by the width of the tab 225. For example, width C1 of one of the channels (channel 230D between wall panel 215D and wall panel 225D) is defined by width E1 of tab 223C-1 of wall panel 225C. In some embodiments, one or more of the widths of the tabs 225 of the inner cooktop 220 can vary. Thus, the width of the channels 230 may also vary. For example, a first width of a first channel (e.g., channel 230C) between

wall plates

215C and 225C may be different than a second width of a second channel (e.g., channel 230B) between

wall plates

215B and 225B.

In some implementations, the distance or width of one or more of the channels 230 may be defined in terms of other dimensions, such as the height of the outer stove 210 and/or the inner stove 220. In some embodiments, the higher the outer cooktop 210, the width of one or more of the channels 230 can be intentionally increased. In some implementations, the channels can reduce convection (e.g., airflow as shown in fig. 6 and 7B) if the width of the channels is increased too much.

As shown in fig. 5, two or more of the channels 230 may be aligned along different directions. Two or more of the channels 230 may be in fluid communication. Two or more of the channels 230 may be disposed between (or defined by) pairs of adjacent wall plates.

For example, channel 230D may be in fluid communication with channel 230C. A pair of

wall plates

225D, 215D can define a channel 230D, and a pair of

wall plates

225C, 215C (which are adjacent to the pair of

wall plates

225D, 215D) can define a channel 230C. Channel 230D is aligned orthogonally to channel 230C. Both

channels

230D and 230C have vertical alignment components along the height of

parallel walls

225D and 215D. For cooktops having fewer than four or more than four walls, the channels may not be aligned orthogonally.

In this embodiment, the inner cooktop 220 is disposed on the combustion chamber base 218 of the outer cooktop 210. In some embodiments, the inner cooktop 220 may be disposed on one or more pins 212 (which may be removably coupled to the outer cooktop 210). In some embodiments, inner stove 220 may also include a combustion chamber base 228 and/or may be disposed on one or more of pins 212. In some implementations, the inner stove 220 may include a combustion chamber base 228 and may be disposed within the outer stove 210 without the combustion chamber base 218 of the outer stove 210.

As shown in fig. 5, the outer cooktop 210 includes a wall plate having a different hole pattern than a corresponding wall plate included in the inner cooktop 210. For example, wall panel 225C of inner stove 220 has a hole pattern that is different from the hole pattern of wall panel 215C of outer stove 210 that corresponds to wall panel 225C (e.g., is on the same side as wall panel 225C, adjacent to wall panel 225C). Similarly, wall panel 225D of inner stove 220 has a hole pattern that is different from the hole pattern of wall panel 215D of outer stove 210 that corresponds to wall panel 225D.

Fig. 6 illustrates a top view of the inner stove 220 disposed in the outer stove 210. The airflow may be drawn (along direction U) onto

channels

230A, 230B, and 230D shown in fig. 6. In some implementations, for example, the airflow in channel 230A may be drawn through space S1. In some embodiments, the airflow may be drawn into the combustion chamber 265 of the inner oven 220 through the space S2 (and the space S1).

As shown in fig. 6, both the inner and

outer cooktops

220, 210 can have at least one bottom surface aligned within the plane 240. In some implementations, both the inner stove 220 and the outer stove 210 may have at least a portion of a bottom surface that contacts or rests on the ground. This may facilitate alignment between the inner stove 220 and the outer stove 210.

Fig. 7A and 7B illustrate top views of the inner cooktop 220 disposed in the outer cooktop 210 with the baffle 250. As shown in fig. 7A, the baffle 250 is slidably movable within a portion of the outer stove 220 and over at least a portion of the inner stove 210. As shown in fig. 7B, when in the nested stove 200 configuration, the baffle 250 slidably moves into a usable position within the outer stove 220. The baffle 250 may have a portion disposed over at least a portion of one or more of the channels 230. For example, the baffle 250 may have a first portion (or side) disposed above the channel 230D. The baffle 250 may have a second portion (or side) disposed above the channel 230C.

When in use, in some embodiments, the deflector 250 can facilitate the movement of combustion air from at least one side (e.g., from the 4-side) (the arrows illustrate the four sides) into the combustion chamber 265 of the inner cooktop 220. For example, combustion air may travel upward (shown by the dashed portion of arrow Z) along the channel 230D, contact the deflector 250 (shown by a portion of arrow Z), and be directed downward (shown by a portion of arrow Z) into the combustion chamber 265 of the inner stove 220.

Fig. 8A and 8B illustrate top views of nested cooktops 200 with an inner stove 220 disposed in an outer stove 210 with a baffle 250.

As discussed above, the inner stove 210, the outer stove 220, and the nested stove 200 may have any shape or profile. For example, one or more of the wall panels may have a trapezoidal shape, a square shape, a triangular shape, and the like. The contours or shapes (in plan view) of the inner stove 210, the outer stove 220, and the nested stove 200 can be tubular shapes, pentagonal shapes, hexagonal shapes, triangular shapes, etc. (where the inner stove 210 and the outer stove 220 are concentrically oriented with respect to each other). Each of these sides may have wall panels of the same length or unequal lengths. In these implementations, the number of channels can be greater or less than, for example, four. The inner stove 210 (wall panel or top view) may have a different shape or profile than the outer stove 220. The inner stove 210 and/or the outer stove 220 may not have a wall plate (e.g., may be made of a single sheet).

Fig. 9A-15 are diagrams illustrating various implementations of nested stoves having non-square profiles or shapes in plan view shown above (e.g., nested stove 100, nested stove 200) (or portions thereof). Although the figures illustrate a single stove profile, the implementation may be an inner stove (e.g., inner stove 110) and/or an outer stove (e.g., outer stove 120). Additionally, implementations can include any of the features described above, including, for example, baffles, tabs, slots, holes, hole patterns, spaces, gaps, channels, pins, and the like.

Fig. 9A and 9B illustrate perspective and top views of a stove 1000 having a hexagonal profile (e.g., shape). As shown in fig. 9B, each of wall panels 1025A-1025F (collectively referred to as wall panels 1025) has an equal width (e.g., width W), although in some implementations, two or more of wall panels 1025 may have different widths. For example, a first wall panel (e.g., wall panel 1025A) may have a different width than a second wall panel (e.g., wall panel 1025B). In some embodiments, the third wall panel (e.g., wall panel 1025C) may have a width that is different than the width of the first wall panel or the width of the second wall panel.

As shown in fig. 9A, in this embodiment, at least some of the wall panels 1025 are vertically offset from other of the wall panels. This offset (e.g., offset O) can provide an opening between the bottom of at least one of the walls and the surface on which the stove 1000 is placed so that the ambient environment (e.g., combustion air) can move into the interior portion of the stove. In some implementations, one or more of the wall panels 1025 may have one or more openings (not shown) for combustion air, ventilation, fuel movement, etc. (e.g., holes 217 and/or holes 227 shown in fig. 2A and 2B).

Although as shown in fig. 9A, each of wall panels 1025 has an equal length (vertically from top to bottom), in some implementations, two or more of wall panels 1025 may have different lengths (e.g., length L). For example, the first wall panel may have a length that is different from the length of the second wall panel. In some embodiments, the third wall panel may have a length that is different from the length of the first wall panel or the length of the second wall panel.

Although each of the wall panels has equal surface area, as shown in fig. 9A, in some implementations, two or more of the wall panels 1025 may have different surface areas. For example, the first wall panel may have a surface area that is different from the surface area of the second wall panel. In some embodiments, the third wall panel may have a surface area that is different from the surface area of the first wall panel or the surface area of the second wall panel.

As described above, in some embodiments, stove 1000 can have fewer (e.g., 5 walls, 3 walls) or more (e.g., 7 walls, 8 walls, 9 walls). In some embodiments, the profile may have different angles between pairs of wall panels 1025 in a top view. For example, the angle (e.g., angle Z) between a first pair of wall panels (when assembled) may be different than the angle (e.g., angle between wall panel 1025C and wall panel 1025D) between a second pair of wall panels. In some embodiments, the profile of the stove 1000 may be asymmetric in plan view. In some embodiments, angle Z between pairs of wall plates 1025 may be an obtuse angle.

Although the stove 1000 has the plates 1025 vertically aligned when assembled, in some embodiments, the stove 1000 may have one or more wall plates that are not vertically aligned when assembled. For example, stove 1000 can have one or more walls that are trapezoidal in shape such that at least one of walls 1025 tilts up or down (e.g., not parallel to the other walls) when assembled.

An example of a wall panel 910 that is not vertically aligned is shown in fig. 10. As shown in fig. 10, the wall plate 910 tapers from a wider top portion 911 to a narrower bottom portion 912.

Fig. 11 illustrates a nested stove configuration in which the inner stove Q1 has a first profile (in plan view) and the outer stove Q2 has a second profile (in plan view). In some implementations, stoves Q1, Q2 may be configured such that one or more portions of the inner stove Q1 contact the outer stove Q2.

Fig. 12A-12D are diagrams illustrating wall panels that may be used to define one or more of the cooktops described above (e.g., inner cooktops, outer cooktops). Fig. 12A illustrates a first side of wall plate 1200, fig. 12B illustrates a second side of wall plate 1200, and fig. 12C illustrates a view of the wall plate as viewed from the bottom side (i.e., direction B) of fig. 12A. Fig. 12D illustrates a wall plate 1200 stacked with several other wall plates that are the same as (or similar to) wall plate 1200.

As shown in fig. 12A, wall plate 1200 includes tab 1210 on a first side of main portion 1201 of wall plate 1200 and tab 1220 on a second side (opposite the first side) of main portion 1201 of wall plate 1200. As shown in fig. 12C, the

tabs

1210, 1220 are each angled (e.g., an angle greater than 90 °) relative to the major plane (and/or major portion) of the panel 1200. Tab 1210 on a first side of panel 1200 is offset (e.g., vertically offset) from tab 1220 on a second side of panel 1200.

As shown in fig. 12D, the wall panel 1200 may be stacked with several other wall panels. Specifically, the panel 1200 may be packaged between

tabs

1210, 1220, the

tabs

1210, 1220 not interfacing with tabs of other panels. The main portion of one of the wall plates may be in contact with the main portion of the other of the wall plates. In some embodiments, the wall panels may be stackable when configured to define a cooktop having at least 5 sides. Stoves with less than 5 walls (in the case of walls with tabs) cannot be stacked.

Although fig. 12A-12D illustrate wall panel 1200 having an equal number (i.e., 4) tabs on each side of wall panel 1200. In some embodiments, however, the number of tabs 1210 may be different than the number of tabs 1220. For example, the number of tabs on the first side of the wall panel may be an odd number and the number of tabs on the second side of the wall panel may be an even number. In some embodiments, the wall panel may have less than 4 tabs or more than 4 tabs on one or more sides.

As shown in fig. 12A and 12B, tab 1210 on one side of the wall panel is vertically offset from tab 1220 on the other side of the wall panel. For example, a tab (or a central portion of a tab) on a first side of panel 1200 is horizontally aligned with a space (or a central portion of a space or gap between tabs) on a second side of panel 1200 rather than with another tab. In some embodiments, the tabs 1210, 1220 (on each side of the panel 1200) of one or more panels in the stove may not be vertically offset. For example, the tabs (or central portions of the tabs) on the first side of the panel 1200 may be horizontally aligned with the tabs (or central portions of the tabs between spaces or gaps) on the second side of the panel 1200.

The tabs disclosed herein (e.g.,

tabs

1210, 1220, tab 123) may have various shapes. For example, one or more of the tabs may have a triangular shape, a square shape, a rectangular shape, or the like. In some implementations, the space (or distance) between a pair of tabs (e.g., space H) is about the same width and/or height (e.g., width or height I) as at least one of the tabs. In some implementations, the space (or distance) between a pair of tabs is of a different width and/or height than at least one of the tabs.

In some embodiments, the spacing (or distance) between the tabs may be uniform, as shown in fig. 12A and 12B. In some embodiments, the spacing (or distance) between the tabs may vary. For example, the space (or distance) between the first pair of tabs may be different than the space (or distance) between the second pair of tabs.

In some embodiments, the width of the tab may be uniform, as shown in fig. 12A and 12B. In some embodiments, the width of the tab may vary. For example, the width of the first tab may be different than the width of the second tab.

The spacing between one or more pairs of tabs, the shape of one or more of the tabs, etc. may be configured such that a pair of panels may be coupled together (relative to each other) in only one orientation. The spacing between one or more pairs of tabs, the shape of one or more of the tabs, etc. may be configured such that a pair of panels may be coupled together in a prescribed number of orientations.

In some embodiments, the angle (e.g., angle M) between one of the tabs (e.g., one of tabs 1210) and the main portion of the panel (e.g., main portion 1201 of panel 1200) may be different than the angle between a second of the tabs and the main portion of the panel. In some embodiments, at least one of the tabs included in the wall panels may not be bent (e.g., may be in the same plane as the main wall panel).

Fig. 13A-13C illustrate wall plate 1310 coupled to wall plate 1320. Fig. 13A illustrates a view of the

wall panels

1310, 1320 as viewed from a first side, and fig. 13B illustrates a view of the

wall panels

1310, 1320 as viewed from a second side. Fig. 13B illustrates a bottom view of the

wall plates

1310, 1320. The

wall panels

1310, 1320 are removably coupled together.

Tab 1310A intersects tab 1320A as shown in fig. 13B. When coupled together, tab 1310A of wall panel 1310 is in contact with the major portion of wall panel 1320, and tab 1320A of wall panel 1320 is in contact with the major portion of wall panel 1310. In other words, wall panel 1310 has tab 1310A and wall panel 1320 has tab 1320A, wherein wall panel 1310 and wall panel 1320 are removably coupled via interlocking tab 1310A and tab 1320A.

Wall panel 1310 and wall panel 1320 may be coupled together in various portions, given the configuration of

tabs

1310A, 1320A. Some of these portions are illustrated in fig. 14A and 14B. Fig. 14A illustrates wall plate 1310 vertically higher than wall plate 1320 when wall plate 1310 is coupled to wall plate 1320. Other wall panels (not shown) may be combined with wall panel 1310 and/or wall panel 1320 in various configurations, such as a vertical high offset (e.g., a vertical offset of up to 50% of the length, a vertical offset of up to 30% of the length). Fig. 14B illustrates wall panel 1310 being more vertically elevated than wall panel 1320 than in fig. 14A.

Although not illustrated, wall panel 1310 (shown in fig. 13B) can be coupled to wall panel 1320 such that tab 1310B can interlock with (e.g., cross over) tab 1320A. In other words, wall plate 1310 may be decoupled from wall plate 1320. Wall plate 1310 is rotatable and coupled to wall plate 1320.

Although not shown, in some embodiments, tabs may be provided on both sides of the main portion of the panels when the panels are coupled together. For example, the first tab of the first panel may be disposed on a first side of the main portion of the second panel and the second tab of the first panel may be disposed on a second side of the main portion of the second panel.

When multiple wall plates are coupled together to define a shape (such as range 1000 in fig. 9A and 9B), tension between the wall plates can maintain the structural integrity of range 1000, as an example. For example, an angle between the tab and the main portion of the first panel (e.g., angle M shown in fig. 12C) may be defined such that when the first and second panels are coupled, tension between the tab and the main portion of the second panel may maintain a relatively secure coupling between the first and second panels.

By way of specific example, the internal angle between a pair of walls in a stove having a hexagonal shape may be 120 °. However, the angle between the tab of the first of the pair of panels and the main portion of the first of the pair of panels may be less than 120 °. Thus, when a pair of panels are coupled together, the tab of a first pair of panels may press-fit into engagement with the main portion of a second of the pair of panels.

As shown for example in fig. 13B, the

walls

1310, 1320 are coupled together without a gap between the sides (main portions other than the tabs) of the

walls

1310, 1320. In some embodiments, the wall plates (e.g., wall plates 1310, 1320) may be configured such that there may be a gap between the sides of the wall plates. Fig. 15 illustrates such an example where there is a gap (or opening) 1550 between tabs 1521 (a portion of wall plate 1520 and shown by cross-hatching), 1511 (a portion of wall plate 1510 and shown by horizontal line) so that side 1512 of wall plate 1510, side 1522 of wall plate 1520 are not in contact. Other tabs are not shown in this exemplary figure.
