The term, "or," as used herein, refers to a non-exclusive or, unless otherwise indicated.
Also, the various ak 02798547 2014-11-26 embodiments described herein are not necessarily mutually exclusive, as some embodiments can be combined with one or more other embodiments to form new embodiments.

[0014] Embodiments of the present disclosure provide a fireplace liner, designed in some embodiments, to obscure or completely hide the burner assembly of the fireplace, to addresses customer demands for a more aesthetically pleasing look, while at the same time meeting requisite technical requirements for air flow to the burner.
[0015] It was found that piling up loose media around and over the burner assembly makes it difficult to achieve satisfactory combustion of fuel, and can obscure the flame itself from view.
Certain embodiments of the fireplace liner of the present disclosure address these problems by providing troughs that promote bilateral secondary air flow to the burner head to produce a taller flame that does not stick to the sides of the liner components. A taller flame, in turn, facilitates embodiments where the burner assembly can be recessed below the liner, and can have the added benefit of giving the appearance of there being more flame than there actually is, for a given amount of fuel flow to the burner.
The width, number of troughs and the secondary air flow through the troughs of the liner can be adjusted thereby providing new variables to control the shape and size of the flame in a manner not previously recognized.

[0020]
As further illustrated for the embodiment shown in FIG. 1, major outer surfaces 140, 145 of the panel 105, 130 lay substantially horizontally on a floor or horizontal surface 150 of the firebox 120.
In some cases the lateral dimension 112 of the burner assembly 110, or portion thereof, e.g., a burner head 240, can extend substantial across the entire firebox 120, e.g., substantially from one wall 155 to an opposing wall (not show) of the firebox 120. As further illustrated, a front end 160 of the first panel 105 is nearest the viewing window 115 of the fireplace box 120, and a rear end 165 of the second panel 130 is nearest a back wall or vertical panel 167 of the fireplace box 120.

[0021]
Bilateral secondary airflow through the plurality of first slots 220 and second slots 235 is thought to be important to promoting a vertical flame to be emitted from the burner head 240 of the assembly 110 and to preventing the flame from a sticking to the first or second panels 105, 130, e.g., sticking the vertical walls 215, 230 of the panels 105, 130.
For instance, in some embodiments of the liner 100, the plurality first slots 220 extend along the entire length 250 of the vertical wall 215 and the plurality of second slots 235 extend along the entire length 255 of the of the other vertical wall 230.
For instance, in some embodiments, the slots 220, 235 are rectangular-shaped openings have a lateral length 260 of 1/2 to 3/4 inches (e.g., parallel with the lateral dimension 112) and vertical length 262 of 1/8 to 1/4 inches. In some such embodiments, secondary airflow through the slots 220, 235 to the burner heed 240 can extend along the lateral dimension 112 of the assembly 110, to promote a vertical flame. However, in other embodiments, the number, size and location of the slots 220, 235 can be adjusted to produce different effects on the flame along the burner head 240.
For instance, in some cases, there can be more slots 220, 235 in the middle than on the ends of the vertical walls 215, 230.
Such a configuration would increase the velocity of secondary airflow to the middle compared to the ends of the burner head 240 and therefore decrease the amount of flame in the middle of the burner head 240. Based on the present disclosure, one of ordinary skill would appreciate how the slots could be varied to produce different flame effects.

[0022]
The width of the troughs 210, 225 is also important to providing secondary airflow through the slots 220, 235 to the burner assembly 110. For instance, as illustrated in FIG. 3, in some cases, the first trough 210 has a width 310 in a range of about 6/8 to about 1 inches and the second trough 225 has width 315 in a range of about 4/8 to about 6/8 inches.
Based on the present disclosure, one of ordinary skill would appreciate how the widths 310, 315 could be varied to produce different flame effects, if desired.

Based on the present disclosure, one of ordinary skill would appreciate how the widths 310, 315 could be varied to produce different flame effects, if desired.
[0023]
As further illustrated in FIG. 2 and 3, in some embodiments of the liner 100, to facilitate further airflow control to the burner assembly 110, the first trough 210 can include a second vertical wall 270 located between the vertical wall 215 and the burner assembly 110.
For instance, in some cases the first panel includes, or is, a single metal sheet 272, the rear end 125 of the metal sheet 272 including at least three substantially right angled bends 320, 322, 324 (e.g., 90 20 degree bends) to define the vertical wall 215 and the second vertical wall 270 of the first trough 210.
In some cases, a base portion 330 of the first trough 210 can be used as a point of attachment (e.g., via screws, bolts, clamps or welds) to an underlying spar structure 335 of the panel 110 that is configured to provide mechanical and shaping support to the panel 110.

,
[0024]
Similarly, the second panel 130 can include, or have, a second single metal sheet 274, the front end 135 of the second metal sheet 274 including at least two substantially right angled bends 340, 342 to define the other vertical wall 230.
In some cases, the front-most portion 345 of the second panel 130 is a horizontal ledge to facilitate attachment to an underlying rear spar structure 350 of the second panel 130 (e.g., via screws, bolts, clamps or welds).
The spar structure 350 is configured to provide mechanical and shaping support to the panel 110.
Similarly, the second panel 130 can include, or have, a second single metal sheet 274, the front end 135 of the second metal sheet 274 including at least two substantially right angled bends 340, 342 to define the other vertical wall 230.
In some cases, the front-most portion 345 of the second panel 130 is a horizontal ledge to facilitate attachment to an underlying rear spar structure 350 of the second panel 130 (e.g., via screws, bolts, clamps or welds).
The spar structure 350 is configured to provide mechanical and shaping support to the panel 110.
[0025] In some embodiments the liner 100 can further include a separate vertical wall 275 between the burner assembly 110 and the other vertical wall 230 to define the second trough 225. However, in other embodiments, a separate vertical wall is not needed, and, the front end 125 of the second panel 130 (e.g., a metal sheet 274 of the panel 130) includes a third right-angled bend to define the vertical wall 275, which can be a second vertical wall of the second trough 225.
[0026]
As further illustrated in FIGs. 2 and 3, in some embodiments of the liner 100, to facilitate further control of the flame height, a second vertical wall 270 of the first trough 210 and a vertical wall 275 (e.g., a separate vertical wall 275 in some cases) of the second trough 225, define a third trough 280 located between the first trough 210 and the second trough 230. In some such embodiments, the burner head 240 is located within the third trough 280 and below tops 360 of the vertical walls 270, 275. In some embodiments, a width 365 of the third trough 280 is in a range of about 7/8 to about 1 1/8 inches.
As further illustrated in FIGs. 2 and 3, in some embodiments of the liner 100, to facilitate further control of the flame height, a second vertical wall 270 of the first trough 210 and a vertical wall 275 (e.g., a separate vertical wall 275 in some cases) of the second trough 225, define a third trough 280 located between the first trough 210 and the second trough 230. In some such embodiments, the burner head 240 is located within the third trough 280 and below tops 360 of the vertical walls 270, 275. In some embodiments, a width 365 of the third trough 280 is in a range of about 7/8 to about 1 1/8 inches.
[0027] In some embodiments, the third trough 280 has a plurality of third slots 370 permitting separate tertiary airflow there-through.
That is, the third slots 370 provide additional airflow to the burner assembly 110 that is not the same airflow as the secondary airflow through first and second slots 220, 235.
That is, the third slots 370 provide additional airflow to the burner assembly 110 that is not the same airflow as the secondary airflow through first and second slots 220, 235.
[0028] In some embodiments of the liner 100, however, there is no need for a second vertical wall 270 of the first trough 210 or a separate vertical wall 275 or another wall 275 of the second trough 225. For instance, in some cases burner walls 290, 292 of the burner assembly 110 can act as vertical walls to define the first and second troughs 210, 225, respectively.
[0029] As also illustrated in FIGs. 2 and 3, in some embodiments of the liner 100, the top surface 140 of the first panel 105 includes, or is, a single continuous piece configured to curve upwards, a highest point of the top surface 140 is higher than a top-most portion of the burner assembly 110 (e.g., the burner head 240 of the assembly 110).
For instance, in some embodiments, the curved top surface 140 of the first panel 105 has a radius of curvature that is in the range of about 20 to about 100 inches, and more preferably about 50 to about 60 inches. For instance, in some embodiments, an underlying spar 335 of the panel 105 provides a curved surface that the top surface 140 of the first panel 105 mounts to and thereby takes on the same curvature.
For instance, in some embodiments, the curved top surface 140 of the first panel 105 has a radius of curvature that is in the range of about 20 to about 100 inches, and more preferably about 50 to about 60 inches. For instance, in some embodiments, an underlying spar 335 of the panel 105 provides a curved surface that the top surface 140 of the first panel 105 mounts to and thereby takes on the same curvature.
[0030] In some cases, having a curved top surface 140 can facilitate hiding the burner assembly 110 over a wider range of viewing angles (e.g., viewing angles through the firebox window 115) than would be the case if the top surface was a planar surface. Having a curved top surface 140 in some cases can additionally, or alternatively, provide more consistent or uniform reflections of light and heat from the flame than a flat panel 105 would.
[0031] In some embodiments of the liner 100, top surfaces 140, 145 of the first panel 105 and the second panel 130 both curve upwards and highest portions of the first panel and the second panel are in a same substantially lateral plane 380.
As illustrated in FIG. 3, in some cases, the lateral plane 380 is above the burner assembly 130 (e.g., above the burner head 240).
Configuring both top surfaces 140, 145 as curved surfaces promotes having continuous visual line from the front first panel 105 to the rear second panel 130, such that a flame from the burner assembly 110 appears to be coming out of the middle of a single panel.

[0032] In some embodiments, to provide a contrasting background for a flame emitted from the burner assembly 110, the top surfaces 140, 145 of the first panel 105 and the second panel 130 both have a dark high glossy finish.
E.g., in some cases, the top surfaces 140, 145 have a black or dark brown porcelain enamel finish.
