Definitions
- the present disclosure relates to outdoor fireplaces and, in particular, an outdoor fireplace having an oven for baking edible goods such as pizza.
- Outdoor fireplaces have become increasingly popular, either as a landscape feature or as part of an outdoor kitchen.
- construction of an outdoor fireplace has been labor intensive and consequently expensive.
- Typical outdoor fireplaces are constructed from brick, block or stone components which are custom built for each installation. In some cases, few of the fireplace components have been constructed at a manufacturing facility, while brick or stone veneer is manually applied at the jobsite.
- Outdoor pizza ovens that use solid fuel e.g. wood, charcoal, pellets, charcoal briquettes, and coal
- solid fuel e.g. wood, charcoal, pellets, charcoal briquettes, and coal
- these outdoor pizza ovens often fail to provide adequate, or proper, and consistent cooking temperatures.
- Classically-styled brick ovens are also often large, heavy, and built-in fixtures, for example, assembled by a skilled craftsman in an end-users' backyard.
- the combination outdoor fireplace and pizza oven is constructed at a manufacturing facility offsite, and is easily transportable to a final location for end use.
- an outdoor fireplace that also facilitates the baking of pizzas, and which is constructed at a manufacturing facility offsite, and is easily transportable to a final location for end use, is surprisingly discovered.
- a combination outdoor fireplace and pizza oven system includes a main body with a framework assembly.
- the framework assembly has a fireplace firebox, an oven firebox, a smokebox, and a chimney flue disposed therein.
- Each of the fireplace firebox and the oven firebox is in communication with the smokebox.
- the smokebox is in communication with the chimney flue.
- the framework assembly is further covered by a refractory heat resistant mortar.
- the oven firebox is suspended above the fireplace firebox and configured for baking pizza.
- the smokebox and the chimney flue are disposed in the framework assembly above both the fireplace firebox and the oven firebox.
- the fireplace firebox is in communication with the smokebox via a first flue duct and a second flue duct.
- the first flue duct is disposed between the oven firebox and a first sidewall of the main body.
- the second flue duct is disposed between the oven firebox and a second sidewall of the main body.
- the fireplace firebox is in communication with the smokebox via a single flue duct.
- the single flue duct is disposed between the oven firebox and a rear wall of the main body. In operation, the smoke and hot gases from the fireplace firebox will flow behind the oven firebox to the smokebox and out through the chimney flue.
- the combination outdoor fireplace and pizza oven system is constructed using structural panels of 2-1 ⁇ 2′′ wide 18′′ gage galvanized U-channels made of top and bottom members that interlock with 2-3 ⁇ 8′′ 18 gage galvanized wide U-channels upright framing members. Each union of the vertical uprights and horizontal top/bottom members is fastened with two screws. Then individual panels are fastened together to create the box-frame assembly of the product, or the skeletal framework.

- the box-iron channels allow access for forklifts, slings, or straps for lifting and positioning the unit.
- the exposed framing also allows access for anchoring the unit to the foundation slab.
- the smokebox collects all the smoke and hot gasses from both fireboxes and reduces the airspace cross-section to a choke-point transitioning into the chimney flue.
- the chimney flue allows the smoke and hot gasses to exit the system.
- the geometry of the smokebox and chimney flue aids in the “draw” of the unit, creating high pressure above the choke-point relative to the low pressure within the firebox, to draw the smoke and hot gasses through the unit and to partially overcome any negative pressure at the firebox opening from cross-winds.
- the present disclosure includes a combination of the fireplace and pizza oven and the dependent and independent variations of the combustion source.

Abstract
Description
- This application is a continuation of U.S. Utility Application No. 15/796,949, filed on Oct. 30, 2017, and issued as U.S. Pat. No. 10.480,793 on Nov. 19, 2019, which claims the benefit of U.S. Provisional Application No. 62/424,581, filed on Nov. 21, 2016. The entire disclosures of the above applications are hereby incorporated herein by reference.
- The present disclosure relates to outdoor fireplaces and, in particular, an outdoor fireplace having an oven for baking edible goods such as pizza.
- Outdoor fireplaces have become increasingly popular, either as a landscape feature or as part of an outdoor kitchen. However, construction of an outdoor fireplace has been labor intensive and consequently expensive. Typical outdoor fireplaces are constructed from brick, block or stone components which are custom built for each installation. In some cases, few of the fireplace components have been constructed at a manufacturing facility, while brick or stone veneer is manually applied at the jobsite.
- Outdoor pizza ovens that use solid fuel (e.g. wood, charcoal, pellets, charcoal briquettes, and coal) are also increasingly popular. However, these outdoor pizza ovens often fail to provide adequate, or proper, and consistent cooking temperatures. Classically-styled brick ovens are also often large, heavy, and built-in fixtures, for example, assembled by a skilled craftsman in an end-users' backyard.
- There is a continuing need for an outdoor fireplace that also facilitates the baking of pizzas. Desirably, the combination outdoor fireplace and pizza oven is constructed at a manufacturing facility offsite, and is easily transportable to a final location for end use.
- In concordance with the instant disclosure, an outdoor fireplace that also facilitates the baking of pizzas, and which is constructed at a manufacturing facility offsite, and is easily transportable to a final location for end use, is surprisingly discovered.
- In one embodiment, a combination outdoor fireplace and pizza oven system includes a main body with a framework assembly. The framework assembly has a fireplace firebox, an oven firebox, a smokebox, and a chimney flue disposed therein. Each of the fireplace firebox and the oven firebox is in communication with the smokebox. The smokebox is in communication with the chimney flue. The framework assembly is further covered by a refractory heat resistant mortar. The oven firebox is suspended above the fireplace firebox and configured for baking pizza. The smokebox and the chimney flue are disposed in the framework assembly above both the fireplace firebox and the oven firebox.
- In another embodiment, the fireplace firebox is in communication with the smokebox via a first flue duct and a second flue duct. The first flue duct is disposed between the oven firebox and a first sidewall of the main body. The second flue duct is disposed between the oven firebox and a second sidewall of the main body. In operation, the smoke and hot gases from the fireplace firebox will flow around the oven firebox to the smokebox and out through the chimney flue.
- In a further embodiment, the fireplace firebox is in communication with the smokebox via a single flue duct. The single flue duct is disposed between the oven firebox and a rear wall of the main body. In operation, the smoke and hot gases from the fireplace firebox will flow behind the oven firebox to the smokebox and out through the chimney flue.
- In an exemplary embodiment, the combination outdoor fireplace and pizza oven system is constructed using structural panels of 2-½″ wide 18″ gage galvanized U-channels made of top and bottom members that interlock with 2-⅜″ 18 gage galvanized wide U-channels upright framing members. Each union of the vertical uprights and horizontal top/bottom members is fastened with two screws. Then individual panels are fastened together to create the box-frame assembly of the product, or the skeletal framework. A skilled artisan may also select other materials and dimensions within the scope of the disclosure, as desired.
- The system comprises a structural framing for lifting and positioning the unit, a fireplace firebox, a pizza oven firebox, a smokebox, and a chimney flue, all of which are contained within the skeletal framework assembly. The pizza oven is suspended above the fireplace firebox. Variations of this configuration permit the pizza oven and the fireplace to function either dependently or independently from each other. The distinction between the two variations is the combustion source.
- In the dependent variation, there is no brick dome over the pizza oven, so it functions as a cooking area rather than as a firebox. A fire in the fireplace firebox below heats the pizza oven cooking area above. In this configuration, the pizza oven cooking area can be either: enclosed and indirectly heated by the combustion source below—acting more like a convection oven; or open to the smoke and heat directly from the combustion source—acting more like a smoker.
- In the independent variation, the pizza oven firebox is insulated from the fireplace firebox—smoke and hot gasses from the fireplace firebox pass around the outside of the insulated pizza oven firebox and proceed into the smokebox. Both fireboxes can function simultaneously and independently of each other. A fire in the pizza oven firebox will only heat that specific space and, vice versa, a fire in the fireplace firebox will only heat that specific space.
- The structural framing for lifting and positioning the unit includes a full-depth panel of U-channel members attached to box-iron channels. The box-iron channels allow access for forklifts, slings, or straps for lifting and positioning the unit. The exposed framing also allows access for anchoring the unit to the foundation slab.
- The smokebox collects all the smoke and hot gasses from both fireboxes and reduces the airspace cross-section to a choke-point transitioning into the chimney flue. The chimney flue allows the smoke and hot gasses to exit the system. The geometry of the smokebox and chimney flue aids in the “draw” of the unit, creating high pressure above the choke-point relative to the low pressure within the firebox, to draw the smoke and hot gasses through the unit and to partially overcome any negative pressure at the firebox opening from cross-winds.
- It should be understood that the present disclosure includes a combination of the fireplace and pizza oven and the dependent and independent variations of the combustion source. An additional useful feature is the combination of these features along with the structural framing for lifting and positioning the unit.
- The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure. The above, as well as other advantages of the present disclosure, will become readily apparent to those skilled in the art from the following detailed description, particularly when considered in the light of the photographs and drawings described hereafter.

InFIGS. 8-10 , a rear-flue embodiment of the combination fireplace andpizza oven system 110 is illustrated. One of ordinary skill in the art may also select alternate suitable flue arrangements for the combination fireplace andpizza oven system - In
FIGS. 1-7 , thesystem 10 includes amain body 12 defined by a framework assembly 14 (shown inFIG. 7 ) covered by a refractory heatresistant mortar 16, and containing afireplace firebox 18, anoven firebox 20, asmokebox 22, achimney flue 24, and abase 26. In particular, the framework assembly 14 includes a framework of steel channel members, as described further hereinbelow. The steel channel members define chambers for thefireplace firebox 18 and theoven firebox 20 within the framework assembly 14. - In certain examples, the framework assembly 14 is formed from galvanized steel channel stock. Galvanized steel channel stock has been found to be particularly suitable for the
system 12, especially compared to aluminum stock, which will warp or melt, or common masonry, which will fracture or crack, at the temperatures and heat cycles associated with operation of conventional fireplaces and pizza ovens. In other examples, the refractory heat resistant mortar may be formed from a mixture of fireclay, cement, and sand, to provide a mortar that is both visually appealing and resistant to the temperatures associated with operation of conventional fireplaces and pizza ovens. One of ordinary skill in the art may select alternative suitable materials for the framework assembly 14 and the refractory heatresistant mortar 16 within the scope of the present disclosure. - As shown in
FIG. 7 , theoven firebox 20 may be suspended above thefireplace firebox 18. The fireplace firebox is configured for burning wood and other suitable fireplace media. Theoven firebox 20 is configured for burning wood and other suitable fireplace media, and also for baking edible goods, such as pizza. Each of thefireplace firebox 18 and theoven firebox 20 are formed from noncombustible or refractory materials. In one nonlimiting example, each of thefireplace firebox 18 and theoven firebox 20 are formed from noncombustible magnesium oxide board and refractory bricks. One of ordinary skill in the art may select other suitable refractory materials for thefireplace firebox 18 and theoven firebox 20, as desired. - In a particular embodiment shown in
FIG. 10 , thefireplace firebox 18 and theoven firebox 20 are thermally insulated from one another. For example, thefireplace firebox 18 and the oven firebox may be separated by an insulating arrangement ofsteel channel members 28,insulation 30 such as mineral wool insulation, and anoncombustible board 32 such as magnesium oxide board. Theinsulation 30 may be disposed within a hollow portion of thesteel channel members 28, between thenoncombustible board 32 of thefireplace firebox 18 and thenoncombustible board 32 of theoven firebox 20, for example. Thenoncombustible board 32 may further be secured to thesteel channel members 28 with fasteners such as screws, bolts, rivets, or the like.Refractory bricks 34 may be laid atop thenoncombustible board 32 to form a floor of theoven firebox 20. Thenoncombustible board 32 may be left uncovered and form a ceiling of thefireplace firebox 18. In this manner, heat transfer between the fireplace andoven fireboxes system 10. Other suitable insulating means are also contemplated and considered within the scope of the present disclosure. - Although the insulative layered construction is specifically shown in
FIG. 10 at the top of thefireplace firebox 18 and the base of theoven firebox 20, it should be appreciated that the layered construction shown may also be used for the various other sides and tops of therespective fireboxes - With renewed reference to
FIG. 7 , thesmokebox 22 and thechimney flue 24 are disposed in the framework assembly 14 above both thefireplace firebox 18 and theoven firebox 20. Thefireplace firebox 18 is in communication withsmokebox 22 through at least oneflue duct flue duct first flue duct 36 and asecond flue duct 38. Thefirst flue duct 36 may be disposed between theoven firebox 20 and afirst sidewall 40 of themain body 12. Thesecond flue duct 38 may be disposed between theoven firebox 20 and asecond sidewall 42 of themain body 12. In operation of thesystem 10, smoke and hot gases from a fire within thefireplace firebox 18 may be directed around the sides of theoven firebox 20. Heat transfer may also be minimized between theducts oven firebox 20 through use of the insulating and refractory materials and the layered construction in forming theoven firebox 20, as described hereinabove. - Another embodiment of the
system 110 is depicted inFIGS. 8-9 . InFIGS. 8-9 , like or related structure fromFIGS. 1-7 and 10 are shown with the same reference number but in a 100-series for purpose of clarity. - The combination outdoor fireplace and
pizza oven system 110 shown inFIGS. 8-9 has asingle flue duct 136. Thesingle flue duct 136 is disposed between theoven firebox 120 and arear wall 144 of themain body 112. In operation, smoke and hot gases from a fire within thefireplace firebox 118 may be directed to the rear of theoven firebox 120. Heat transfer may also be minimized between thesingle flue duct 136 and theoven firebox 120 through use of insulating and refractory materials and the layered construction in forming theoven firebox 120, as described hereinabove. - It should be appreciated that the embodiment of the
system 110 depicted inFIGS. 8-9 may permit for a construction with a narrower width, but greater depth, in comparison to the embodiment of thesystem 10 shown inFIGS. 1-7 . Otherwise, the skilled artisan will understand that thesystems respective fireboxes - With renewed reference to
FIGS. 1-7 , each of thefireplace firebox 18 and theoven firebox 20 has anopening front wall 50 of the main body. Theopening 48 of theoven firebox 20 may be selectively closed by anoven door 52. Theoven door 52 may be hingedly attached to thefront wall 50 of themain body 12, for example. In certain examples, theoven door 52 is formed from stainless steel. Theoven door 52 may have a grate that may be selectively opened and closed in order to control a supply of air to a fire burning within theoven firebox 18. Theoven door 52 may be provided of other suitable materials and have other suitable configurations, as desired. - As shown in
FIG. 7 , thesmokebox 22 is defined by an area above adome 53 of theoven firebox 20 and a lower wall of the chimney flue 55. In particular embodiments, thedome 53 is formed by a plurality of interlocking bricks disposed in an arch. Avent 57 may be formed through an upper portion of thedome 53, and provides the communication between the interior of theoven firebox 20 and thesmokebox 22. In operation, smoke and hot gases from theoven firebox 20 travel through thevent 57 and into thesmokebox 22, where they collect and mix with the hot gases and smoke from theunderlying fireplace firebox 18. - The
smokebox 22 of the system is configured to collect smoke and hot gases from both thefireplace firebox 18 and theoven firebox 20. Thesmokebox 22 is also dimensioned to reduce an airspace cross-section to a choke-point 54, which transitions into thechimney flue 24. Advantageously, the reduced airspace cross-section of thesmokebox 22 aides in creating a higher pressure above the choke-point 54 relative to a lower pressure within thefireplace firebox 18 in operation, so as to draw the smoke and the hot gases through thesmokebox 22 and into thechimney flue 24, even when there is a crosswind in front of theopen fireplace firebox 18. - Although not specifically shown, it should be understood that the
chimney flue 24 may include a chimney damper or flap inside or at a top of thechimney flue 24, which can be adjusted manually to allow smoke to escape or air to enter. The chimney damper may be formed of metal or ceramic so as to tolerate the heat from the smoke and hot gases. The chimney damper may be opened and closed through a variety of suitable mechanisms, for example, a latch, a pull chain, or a handle, as desired. - In further embodiment, the
system 10 may include abase 26. Thebase 26 is disposed beneath thefireplace firebox 18, and is configured to facilitate a transport of the combination outdoor fireplace andpizza oven system 10, for example, from a location of manufacture to an end user's location. The base 26 may include a pair ofholes 56 formed in thefront wall 50 of thebase 26. Advantageously, the pair ofholes 56 are configured to receive at least one of forklifts, slings, and straps for lifting and positioning the combination outdoor fireplace andpizza oven system 10. - In a particular example, the
holes 56 may be defined by a pair of box-iron channels 58 connected to the framework assembly 14. In other examples, and the box-iron channels 58 may project outwardly from themain body 12 to define astep 60 of the combination outdoor fireplace and pizza oven system. Other suitable means of forming theholes 56 to securely and conveniently move thesystem 10 are also considered within the scope of the present disclosure. - Advantageously, the combination outdoor fireplace and
pizza oven system - While certain representative embodiments and details have been shown for purposes of illustrating the invention, it will be apparent to those skilled in the art that various changes may be made without departing from the scope of the disclosure, which is further described in the following appended claims.
