Abstract
A wood burning stove is provided. The combustion chamber in which the fire occurs has a baffle plate that is moveable to direct air flow through one of two different pathways from the combustion chamber to the chimney. When in a first position, the baffle plate forces the air and smoke to move through a first pathway; when in a second position, a by-pass pathway is opened, allowing air and smoke to move through a second pathway. The stove can have a door in the front wall, or the top wall, or both walls, to provide access to the combustion chamber.
Description




FIELD OF THE DISCLOSURE




This disclosure relates generally to wood burning stoves. In particular, this disclosure relates to wood burning stoves having a baffle for regulation of air flow within the stove, and methods of using the stove.




BACKGROUND OF THE DISCLOSURE




Whether for providing heat, for purely decorative purposes, or for value enhancement, wood burning stoves have become commonplace in today's building trades for both residential and commercial applications for situations where a fireplace is not feasible or desired. In some instances, wood burning stoves have been inserted into fireplace boxes. Stoves are often preferred over open fireplaces because many wood stoves have the capability to heat large spaces efficiently. Most stoves are able to burn for extended periods of time, such as over night, without refueling or reloading, further enhancing the preference over fireplaces.




With this extended burning of wood as the primary fuel comes the challenge of providing an efficient stove that meets the Environmental Protection Agency requirements and state agency requirements for emissions, including particulate material and gases. Many wood burning stoves utilize a catalytic combustor to finalize the burning process and reduce particulate materials and gases. However, the catalytic combustors can become fouled or otherwise rendered inefficient, especially when other than selected materials are burned within the stove. Additionally, the catalytic combustors are quite expensive and must be periodically replaced.




In order to avoid using a catalytic combustor, many stove designs are aimed at providing optimum airflow within the burning chamber so that complete combustion, reduction of particulates and unburned gases, and optimum heat generation are obtained. The airflow patterns are generally created by the addition of various channels and/or baffles within the stove, in particular, within the main combustion chamber, to create a secondary combustion chamber. The use of fixed or stationary baffle plates for manipulating air flow within the combustion chamber are known for wood burning stoves, and are discussed, for example, in U.S. Pat. No. 4,766,876 (Henry et al.), U.S. Pat. No. 5,113,843 (Henry et al.), and U.S. Pat. No. 5,341,794 (Henry et al.), each of which is incorporated in its entirety herein by reference.




Depending on the design of the various channels or baffles, loading of wood into the stove can be hampered. For example, some baffles are positioned extending essentially parallel to the top surface of the stove. If the stove is a top-loading stove, that is, where wood can be inserted into the combustion chamber through the top surface of the stove, such baffles hinder access to the combustion chamber. What is desired is an improved stove design having optimal air flow patterns to increase combustion efficiency, reduce emissions, and provide easy access to the combustion chamber.




SUMMARY OF THE DISCLOSURE




The present disclosure provides a stove, in particular, a wood burning stove, that has a baffle assembly disposed within to provide optimal air flow patterns within the stove. A portion of the baffle assembly is pivotable to provide easy access to the combustion chamber to allow loading of fuel into the stove.




In particular, the stove includes a stove body which defines a stove exterior, a stove interior, and a combustion chamber disposed within the interior. A baffle plate is disposed within the combustion chamber, the baffle plate being moveable from a “closed” configuration to an “open” configuration. When in the “closed” configuration, the baffle plate is positioned substantially horizontally and is spaced apart from at least a portion of at least one wall. When in the “open” configuration, the baffle plate is positioned substantially vertically such that a by-pass pathway is created between a top access door and the combustion chamber. This allows for easy top-loading of fuel.




When in the “closed” configuration, air within the combustion chamber flows from the combustion chamber, around the baffle plate, through a passage between the baffle plate and the stove body, and out a chimney. When in the “open” configuration, a by-pass pathway is formed separate from the passage, so that air within the combustion chamber flows from the combustion chamber, through the by-pass pathway, and out the chimney. The by-pass pathway does not exist if the baffle plate is in the closed configuration. Preferably, the baffle plate is pivotable.




An air manifold is preferably present within the combustion chamber, having air flow communication with the exterior of the stove. In one embodiment, the air manifold provides a pivot point for the baffle plate. In one such embodiment, the baffle plate and the air manifold pivot together.




It will also be understood that while a wood fueled stove will be described with respect to the preferred embodiments, the disclosure is not limited to wood burning structures, but could equally apply to stove using other fuel sources. Further, while the present disclosure will be described made of sheet metal material, the disclosure is not to be limited to any particular material, but could be used with other known constructions, such as ceramic and other known materials. These and other modifications of the disclosure will be understood by those skilled in the art in view of the following description of the disclosure, with reference to specific preferred embodiments thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Wood is generally burned in the stove, although other types of solid fuels can also be burned in the stove. The following description and figures are in reference to a wood burning stove, although it is to be understood that the function of the stove elements is not dependent on the type of fuel burned.




A stove


10


is shown in FIG.


1


. Stove


10


has an enclosed body


12


defined by first side wall


14


, opposite second side wall


16


, a top wall


17


, a front wall


18


, a bottom wall


19


, and a back wall, not shown. Together, these various walls define an combustion chamber within the walls. Although body


12


is described with six walls (four periphery side walls, a top wall and a bottom wall), body


12


can be any shape. In general, the body


12


is defined by a top wall, a bottom wall, and at least one side wall. Body


12


is situated on a pedestal or foot


15


, which elevates body


12


above the surface on which it is supported. Typically, stove


10


is metal, such as cast iron.




A first door


20


is disposed within front wall


18


, however, a door such as first door


20


can be provided in any of side walls


14


,


16


, front wall


18


or the back wall of stove


10


. Door


20


is pivotally openable by hinges


22


attached to front wall


18


. A handle


25


facilitates opening and closing of door


20


. Door


20


can include a window


24


to allow viewing of the combustion chamber within the stove


10


. A second door


30


is disposed within top wall


17


and is pivotally openable by hinges (not shown) attached to top wall


17


. Door

may include a handle or other mechanism to facilitate opening and closing of door


30


. Each of doors


20


,


30


can be used to place fuel, such as wood logs, into the combustion chamber of stove


10


.




A stack, flue or chimney


40


is provided to allow the exhaust gases generated by the burning fuel to exit the stove


10


. Included in stove


10


are various air intake apertures and channels, to provide air to the interior of the combustion chamber. Handles


42


,


44


can be used to manipulate the flow of intake air.




The above description of stove


10


has been fairly general. It is understood that any variation in the structure of stove


10


can be used with the moveable baffle assembly of the present disclosure.




Stove


10


, in accordance with the present disclosure, includes a handle


75


extending from body


12


. Handle


75


, which is part of a handle assembly, extends into the combustion chamber and is moveable as desired to manipulate the baffle assembly contained within the combustion chamber. The baffle assembly and its various elements will be now explained in detail, with reference to a first embodiment shown in

FIGS. 2 and 3

, and a second embodiment shown in

FIGS. 12 and 13

.




Referring now to

FIGS. 2

,


3


,


12


, and


13


, stove


10


is shown in side view with the baffle assembly of the present disclosure viewable through the stove body. The baffle assembly of the present disclosure generally includes a baffle plate


50


,


150


, an air manifold


60


,


160


, and mounting members


80


,


180


fixed to the combustion chamber side of the side walls. A handle assembly


70


,


170


is provided to facilitate moving baffle plate


50


,


150


. A fixed baffle plate


56


,


156


is also included in the baffle assembly shown.





FIGS. 4 through 7

show various elements of a first embodiment of the baffle assembly. In

FIG. 4

, the various elements are shown in exploded view; in

FIGS. 5 through 7

, a portion of the baffle assembly is shown. In particular, in accordance with the present disclosure and shown in each of

FIGS. 4 through 7

, a moveable baffle plate


50


is provided. Baffle plate


50


has a generally planar, solid face


52


. Various strengthening features, such as ribs and the like, may be included in or on baffle plate


50


. A fixed baffle plate


56


, shown in

FIG. 4

, is also provided in the baffle assembly. Fixed baffle plate


56


is fixed to the combustion chamber side of the back wall of the stove


10


. Baffle plates


50


,


56


are typically made from a sheet of metal, such as steel or cast iron, although other materials, such as ceramic materials, can be used.




Disposed proximate to baffle plate


50


is an air manifold


60


for providing and further manipulating air flow within the combustion chamber. The air manifold creates a secondary combustion area beneath the baffle plate and above the primary combustion area. Both the primary and secondary combustion areas are located in the combustion chamber. Air manifold


60


includes a first manifold section


62


and a second manifold section


64


. In particular, first manifold section


62


is shown as an axial structure about which the manifold


60


can be pivoted, and second manifold section


64


is a D-shaped structure extending out from first section


62


. Manifold sections


62


,


64


are tubular structures that allow air flow there through. Air enters manifold


60


via intake


65


and exits manifold sections


62


,


64


through apertures


68


disposed within manifold sections


62


,


64


. Preferably, a portion of air manifold


60


, specifically a portion having intake


65


, is in air flow communication with the exterior of the stove body


12


. In one embodiment, intake


65


is connected to channels within the mounting members


80


that are connected to the exterior of the stove


10


. These channels may meet the exterior at the stove sides, stove back, or at other locations.




Baffle plate


50


is connected to second manifold section


64


at connection point


54


and to first manifold section


62


at connection point


55


. Together, baffle plate


50


, air manifold


60


, and fixed baffle plate


56


manipulate the air and smoke flow within the combustion chamber of stove


10


so that optimum temperature and combustion are realized therein.




Mounting members


80


are positioned adjacent to, and typically attached to, the combustion chamber side of the side walls. Mounting members


80


provide a seat or support against which the baffle plate


50


can rest when baffle plate


50


is in the “closed” position. Mounting members


80


may manipulate the air flow patterns somewhat. At least a portion of the mounting members


80


typically extends into the combustion chamber some distance from the wall on which it is attached.




Although mounting members


80


are shown as two oppositely placed pieces (see FIG.


4


), mounting member


80


can be a single structure positioned on only one side wall


14


of


16


, or on the front wall


18


, or on the back wall. Alternately, mounting member


80


can be a single structure that is positioned on two or more walls. Further, in some embodiments it may be desirable to incorporate fixed baffle plate


56


with mounting member


80


, thus having one structure that provides the desired air flow pattern and supports the moveable baffle plate


50


.




The baffle assembly further includes a handle assembly


70


constructed to connect to, and move, baffle plate


50


and manifold


60


from the “open” to the “closed” configuration. Handle assembly


70


has a first position and a second position; when in the first position, the baffle plate


50


is in its “open” configuration, and when in the second position, the baffle plate


50


is in its “closed” configuration.




Handle assembly


70


includes a first section


72


, second section


74


, and third section


76


, which are connected together and to baffle plate


50


. A handle


75


is connected to first section


72


and is disposed on the exterior of stove


10


so that a consumer can grab and move handle


75


as desired. Although shown with three sections


72


,


74


,


76


, it is understood that any handle assembly


70


configuration can be used to move baffle plate


50


.




When the baffle assembly is disposed within the stove, baffle plate


50


is moveable, preferably pivotable, from an “closed” configuration to an “open” configuration. Baffle plate


50


and air manifold


60


are mounted within stove


10


in any manner to allow the desired movement from the “closed” configuration to the “open” configuration. In one embodiment, air manifold


60


is pivotally attached to mounting members


80


, for example, in close proximity to intake


65


. In such an attachment design, first manifold section


62


is an axis for rotation, or pivoting, of manifold


60


. Because baffle plate


50


is attached to manifold


60


at points


54


,


55


, baffle plate


50


will move in congruence with manifold


60


. In another embodiment, the pivoting of baffle plate


50


and manifold


60


are fixedly attached to handle assembly


70


; this point of attachment is the pivot point. See for example,

FIG. 7

, in which reference numeral P designates a potential pivot point.





FIGS. 14 through 18

show various elements of a second embodiment of the baffle assembly, in which the air manifold is expanded. In

FIG. 18

, the various elements are shown in exploded view; in

FIGS. 14 through 17

, a portion of the baffle assembly is shown. In particular, in accordance with the present disclosure and shown in each of

FIGS. 14 through 18

, a moveable baffle plate


150


is provided. Baffle plate


150


has a generally planar, solid face


152


. Various strengthening features, such as ribs and the like, may be included in or on baffle plate


150


. A fixed baffle plate


156


, shown in

FIG. 18

, is also provided in the baffle assembly. As shown in

FIG. 18

, fixed baffle plate


156


is fixed to the combustion chamber side of the back and/or side walls of the stove


10


via rear mounting member


204


. It is to be understood that fixed baffle plate


156


can alternatively be fixed to the rear portion of the mounting members


180


. Baffle plates


150


,


156


are typically made from a sheet of metal, such as steel or cast iron, although other materials, such as ceramic materials, can be used for baffle plates


150


,


156


.




Disposed proximate to baffle plate


150


is an air manifold


160


for providing and further manipulating air flow within the combustion chamber. The air manifold creates a secondary combustion area beneath the baffle plate and above the primary combustion area within the combustion chamber. Air manifold


160


includes a first manifold section


162


, a second manifold section


164


, a third manifold section


200


, and a fourth manifold section


201


. In the illustrated embodiment, first, second, and third manifold sections


162


,


164


,


200


are shown as tubular structures connected to end pieces


205


about which the first, second, and third manifold sections


162


,


164


,


200


can be pivoted. A fourth, fixed, manifold section


201


is a tubular structure extending between, and fixed to, mounting members


180


. Manifold sections


162


,


164


,


200


,


201


are tubular structures that allow air flow there through. Air enters manifold


160


via intake


165


and exits manifold sections


162


,


164


,


200


through apertures


168


disposed within manifold sections


162


,


164


,


200


. Air enters fourth manifold section


201


via intake


210


and exits through apertures


168


disposed within fourth manifold section


201


. Preferably, a portion of air manifold


160


, specifically a portion having intake


165


, is in air flow communication with the exterior of the stove body


12


. Additional intake


210


is in air flow communication with the fourth tubular section


201


and with the exterior of the stove body


12


. In one embodiment, intakes


165


,


210


are connected to channels


250


,


260


, respectively, within mounting members


180


that are connected to the exterior of the stove


10


. These channels may be joined together under mounting members


180


and exit through the wall of the stove as a single channel, or they may exit separately. These channels may meet the exterior at the stove sides, stove back, or at other locations.




Baffle plate


150


is connected to end pieces


205


. Together, baffle plate


150


, air manifold


160


, and fixed baffle plate


156


manipulate the air and gas flow within the combustion chamber of stove


10


to create a secondary combustion area above the primary combustion area so that optimum temperature and combustion are realized in the stove. In one embodiment, insulation panels


202


,


203


are included in the baffle assembly. Insulation panels


202


,


203


are constructed of insulating material to reflect heat back into the combustion chamber from the baffle assembly and thereby maximize the temperature within the combustion chamber during all burn conditions, and thereby encouraging secondary and tertiary combustion above the fuel bed. In a further embodiment, the insulation panels


202


,


203


may also provide structural support for the baffle plates


150


,


156


. The insulation panels


202


,


203


may be made of any suitable insulating material. In one embodiment, the insulation panels


202


,


203


are ceramic.




Mounting members


180


are positioned adjacent to, and typically attached to, the combustion chamber side of the side walls. Mounting members


180


provide a seat or support against which the baffle plate


150


can rest when baffle plate


150


is in the “closed” position. Mounting members


180


may manipulate the air flow patterns somewhat. At least a portion of mounting members


180


typically extends into the combustion chamber some distance from the wall on which it is attached.




Although mounting members


180


are shown as two oppositely placed pieces (see FIG.


18


), mounting members


80


can be a single structure positioned on only one side wall


14


of


16


, or on the front wall


18


, or on the back wall. Alternately, mounting members


180


can be a single structure that is positioned on two or more walls. Further, in some embodiments it may be desirable to incorporate fixed baffle plate


156


with mounting members


180


, thus having one structure that provides the desired air flow pattern and supports the moveable baffle plate


150


.




The baffle assembly further includes a handle assembly


170


constructed to connect to, and move, baffle plate


150


and manifold


160


from the “open” to the “closed” configuration. Handle assembly


170


has a first position and a second position; when in the first position, the baffle plate


150


is in its “open” configuration, and when in the second position, the baffle plate


150


is in its “closed” configuration.




Handle assembly


170


includes a first section


172


, second section


174


, and third section


176


, which are connected together and to baffle plate


150


. A handle


175


is connected to first section


172


and is disposed on the exterior of stove


10


so that a consumer can grab and move handle


175


as desired. Although shown with three sections


172


,


174


,


176


, it is understood that any handle assembly


170


configuration can be used to move baffle plate


150


.




When the baffle assembly is disposed within the stove, baffle plate


150


is moveable, preferably pivotable, from an “closed” configuration to an “open” configuration. Baffle plate


150


and air manifold


160


are mounted within stove


10


in any manner to allow the desired movement from the “closed” configuration to the “open” configuration. In one embodiment, air manifold


160


is pivotally attached to mounting members


180


through end pieces


205


, for example, in close proximity to intake


165


. In such an attachment design, the end pieces


205


provide an axis for rotation, or pivoting, of manifold


160


. Because baffle plate


150


is attached to manifold


160


, baffle plate


150


will move in congruence with manifold


160


. In another embodiment, the pivoting of baffle plate


150


and manifold


160


are fixedly attached to handle assembly


170


; this point of attachment is the pivot point. See for example,

FIG. 15

, in which reference numeral P designates a potential pivot point.




Referring to

FIGS. 8 and 9

, partial side views of stove


10


are shown with the baffle plate


50


in the “closed” and “open” configurations, respectively. The pivot point for these embodiments is intake


65


. In both

FIGS. 8 and 9

, the air flow pattern, mostly the flow pattern of smoke and combustion gases, is depicted by the arrows


300


,


301


.




In

FIG. 8

, the baffle plate


50


is in the “closed” configuration with baffle plate


50


seated against mounting members


80


. In this configuration, the baffle plate


50


is spaced apart from at least a portion of the front wall


18


forming a passage


400


from the combustion chamber to the chimney


40


. The passage


400


may be formed in any location where the baffle plate is spaced apart from at least a portion of a side wall. Handle


75


is in a first position. Baffle plate


50


, and air manifold


60


, are substantially horizontal. Smoke and gases rise from the burning wood, (not shown, but which is typically on the base wall of the stove), and is directed by baffle plate


50


toward front wall


18


. The smoke and gases flow generally parallel to baffle plate


50


. The smoke and gases then pass through the passage


400


, around and over baffle plate


50


and mounting members


80


, and flow out chimney


40


, as indicated by arrow


300


.




In

FIG. 9

, handle


75


is in a second position and the baffle plate


50


is in the “open” configuration with baffle plate


50


not seated against mounting members


80


; baffle plate


50


is displaced from its seat on mounting members


80


and a by-pass pathway


100


, separate from passage


400


, is opened. In the position shown, baffle plate


50


and air manifold


60


are substantially vertical, and the by-pass pathway


100


is formed between the “open” baffle plate


50


and the fixed baffle


56


. With baffle plate


50


pivoted to the “open” position, smoke and gases are able to move through by-pass pathway


100


, as indicated by arrow


301


. The smoke and gases flow generally parallel to baffle plate


50


through by-pass pathway


100


. In

FIG. 9

, stove


10


is also shown with door


30


opened to provide access from the exterior to the interior of stove


10


.





FIGS. 10 and 11

show schematic top views of stove


10


. In

FIG. 10

, door


30


is closed, and baffle plate


50


and manifold


60


are in the “closed” configuration; in

FIG. 11

, door


30


is open, and baffle plate


50


and manifold


60


are in the “open” configuration. It can be seen that when in the “open” configuration, access into the combustion chamber of stove


10


is generally unobstructed.




Fuel, such as wood, can be loaded into stove


10


by various methods. In one embodiment, first door


20


can be pivoted on hinges


22


to open an access port to the combustion chamber. Prior to opening door


20


, handle


75


is optionally moved from its first position to its second position, thereby moving baffle plate


50


from the “closed” configuration to the “open” configuration. Moving baffle plate
