Fuel and air mixtures are generally introduced into such burners utilizing either of two methods. Certain multi-ring burners include vertically oriented mixing tubes, and other multi-ring burners include horizontally oriented mixing tubes. Each design has certain drawbacks.
- Multi-ring burners with horizontally oriented mixing tubes can generally accommodate larger/longer mixing tubes thereby improving air and fuel mixing. Further, such burners can have a relatively low pressure gradient within the burners due to the relatively low velocity of the air/fuel mixture entering the burner head.
- multi-ring burners with horizontally oriented mixing tubes are generally costly to construct and difficult to service. Further, despite the relatively low pressure gradient within such burners, the air/fuel mixture exiting such burners' outlets can have uneven or non-uniform flames along the outlets.
- Multi-ring burners with vertically oriented mixing tubes can be easy to construct and service. However, such burners can occupy more depth below the cooktop appliance's cooking surface.

The smaller outlets adjacent the mixing tubes can reduce the velocity of the air/fuel mixture exiting such outlets, particularly at higher air/fuel flow rates. However, at relatively low air/fuel flow rates where the internal pressure is substantially uniform, such multi-ring burners can have similar problems described above with the air/fuel mixture exiting such burners' outlets with different flow rates and pressures thereby leading to uneven flames along the outlets.

Description
- The present subject matter relates generally to gas burners for appliances, such as cooktop appliances.
- Certain cooktop appliances include multi-ring gas burners. Such burners can include a center burner surrounded by one or more concentric burner rings. Fuel and air mixtures are generally introduced into such burners utilizing either of two methods. Certain multi-ring burners include vertically oriented mixing tubes, and other multi-ring burners include horizontally oriented mixing tubes. Each design has certain drawbacks.
- Multi-ring burners with horizontally oriented mixing tubes, e.g., the one shown in U.S. Patent Application No. 2012/0070791, can generally accommodate larger/longer mixing tubes thereby improving air and fuel mixing. Further, such burners can have a relatively low pressure gradient within the burners due to the relatively low velocity of the air/fuel mixture entering the burner head. However, multi-ring burners with horizontally oriented mixing tubes are generally costly to construct and difficult to service. Further, despite the relatively low pressure gradient within such burners, the air/fuel mixture exiting such burners' outlets can have uneven or non-uniform flames along the outlets.
- Multi-ring burners with vertically oriented mixing tubes can be easy to construct and service. However, such burners can occupy more depth below the cooktop appliance's cooking surface. Further, such burners generally have a higher pressure gradient within the burners due to the relatively high velocity of the air/fuel mixture exiting the vertically oriented mixing tubes. Thus, the air/fuel mixture exiting such burners' outlets can have different flow rates and pressure drops thereby leading to uneven flames along the outlets.
- To alleviate such non-uniformity, certain multi-ring burners include outlets having varying sizes. Such multi-ring burners can have relatively smaller outlets positioned adjacent the mixing tubes where the pressures are highest. The smaller outlets adjacent the mixing tubes can reduce the velocity of the air/fuel mixture exiting such outlets, particularly at higher air/fuel flow rates. However, at relatively low air/fuel flow rates where the internal pressure is substantially uniform, such multi-ring burners can have similar problems described above with the air/fuel mixture exiting such burners' outlets with different flow rates and pressures thereby leading to uneven flames along the outlets.
- Alternatively, various multi-ring burners include a baffle positioned within the multi-ring burners adjacent the mixing tubes. Such baffles can decrease the speed of the air/fuel mixture entering the outlets adjacent the mixing tube(s). However, baffles can cause turbulence and recirculation of the air/fuel mixture proximate the adjacent outlets within the burner and have proven to have limited effectiveness in practice.
- Accordingly, a multi-ring gas burner with features for improving uniformity of flames along outlets of the burner would be useful. In particular, a multi-ring gas burner with features for efficiently or economically improving uniformity of flames along outlets of the burner would be useful. Further, a multi-ring gas burner with features for improving uniformity of flames along outlets of the burner at both relatively high and relatively low fuel flow rates would be useful.
- The present subject matter provides a multi-ring gas burner for an appliance. The burner includes an inner burner ring and an outer burner ring. The outer burner ring has a regulator positioned within a fuel chamber of the outer burner ring. The regulator controls a flow of fuel to outlets of the outer burner ring adjacent the regulator. The regulator can improve a uniformity of fuel flow through the outlets and thereby improve a uniformity of flames at the outlets.

FIGS. 2 and 3 ,inlets 224 include afirst inlet 240 and asecond inlet 242.First inlet 240 is spaced apart fromsecond inlet 242 by about one-hundred and eighty degrees along the circumferential direction C. In alternative exemplary embodiments,first inlet 240 may be spaced apart fromsecond inlet 242 by any suitable amount, e.g., about ninety degrees, about sixty degrees, or any other suitable angle. - As will be understood by those skilled in the art, a velocity of the fuel entering
fuel chamber 226 through first andsecond entrances fuel chamber 226 such that fuel exiting fuel chamber throughoutlets 228 has different velocities and/or flow rates at various outlets ofoutlets 228. For example, fuel exiting certain outlets ofoutlets 228 can have a greater velocity and/or flow rate relative to fuel exiting other outlets ofoutlets 228.Burner 200 includes features for regulating and/or controlling a flow of fuel throughoutlets 228. Such features can improve a uniformity of fuel flow throughoutlets 228 and thereby improve a uniformity of flames atoutlets 228. - In particular,
burner 200 includes aregulator 230 for regulating and/or controlling a flow of fuel throughoutlets 228 as discussed in greater detail below.Regulator 230 is mounted toouter burner ring 220 withinfuel chamber 226 ofouter burner ring 220.Regulator 230 is positioned adjacent one ofinlets 224. Inparticular regulator 230 is positioned adjacentfirst inlet 240.Regulator 230 is disposed betweenfirst inlet 240 and at least twooutlets 236 ofoutlets 228 along the radialdirection R. Regulator 230 defines at least twoslots 232.Slots 232 are positioned adjacentfirst inlet 240 and, in particular, between the at least twooutlets 236 andfirst inlet 240 along the radial direction R. -
Regulator 230 is configured such that fuel fromfuel chamber 226 is hindered from entering a regulatingchamber 234 and the at least twooutlets 236 except throughslots 232. Thus,regulator 230 extends upwardly from an interior surface 221 ofouter burner ring 220, e.g., along the axial direction.Regulator 230 extends upwardly from interior surface 221 to cover 222 whencover 222 is positioned onouter burner ring 220 as shown inFIG. 2 , e.g., in order to hinder fuel from enteringfuel chamber 226 except throughslots 232. -
Burner 200 also includes anadditional regulator 250 mounted toouter burner ring 220 withinfuel chamber 226 ofouter burner ring 220.Additional regulator 250 is spaced apart fromregulator 230 along the circumferential direction C.Additional regulator 250 is positioned adjacentsecond inlet 242 and, in particular, betweensecond inlet 242 and at least twoother outlets 254 ofoutlets 228 along the radial direction R.Additional regulator 250 also defines at least twoslots 252 that function in a similar manner toslots 232 ofregulator 230. Operation and function ofregulator 230 is discussed in greater detail below; however,additional regulator 250 operates and functions in a similar manner and includes similar features. -
FIG. 4 provides a top, plan view ofburner 200. As may be seen inFIG. 4 ,regulator 230 andouter burner ring 220 define a regulatingchamber 234, e.g., therebetween.Regulator 230 is configured for directing fuel fromfuel chamber 226 ofouter burner ring 220 throughslots 232 ofregulator 230 into regulatingchamber 234. Fuel within regulatingchamber 234 can flow out of regulatingchamber 234 through the at least twooutlets 236 ofoutlets 228. -
Slots 232 ofregulator 230 can impart friction losses to a velocity of fuel passing throughslots 232 and entering regulatingchamber 234, thereby reducing the pressure within the regulatingchamber 234. By reducing the pressure of fuel within regulatingchamber 234 and allowing it to expand, the pressure within regulatingchamber 234 becomes substantially uniform, e.g., about equal to the pressure withinfuel chamber 226. Thus, fuel can exit each outlet ofoutlets 228 at about a uniform pressure and velocity and flames at each outlet ofoutlets 228 can be uniform as well. Certain features ofregulator 230 can assist with reducing the velocity and/or pressure of fuel within regulatingchamber 234. - In particular,
slots 232 ofregulator 230 and the at least twooutlets 236 ofoutlets 228 are unaligned along the radial direction R such thatslots 232 and the at least twooutlets 236 are non-collinear along the radial direction R. Further,slots 232 may be sized relative to the at least twooutlets 236 ofoutlets 228 to assist with reducing the pressure of fuel within regulatingchamber 234. In particular, each slot ofslots 232 has a cross-sectional area in a plane that is perpendicular to the radial direction R, and each outlet of the at least twooutlets 236 has a cross-sectional area in a plane that is perpendicular to the radial direction R. A total cross-sectional area ofslots 232 may be less than a total cross-sectional area of the at least twooutlets 236 ofoutlets 228. In particular, the total cross-sectional area ofslots 232 may be between about forty percent and about sixty percent, between about forty-five percent and about fifty-five percent, or about fifty percent of the total cross-sectional area of the at least twooutlets 236 ofoutlets 228. -
FIG. 5 provides a section view ofburner 200. As may be seen inFIG. 5 ,inlets 224 ofouter burner ring 220 andentrance 214 ofinner burner ring 210 includeVenturi mixing tubes 260 for assisting with mixing of fuel and air enteringouter burner ring 220 andinner burner ring 210. As discussed above,burner 200 includes features for regulating and/or controlling a flow of fuel throughoutlets 228. - As an example, during operation of
burner 200, a fuel and air mixture can flow intoburner 200. In particular, such fuel and air mixture can enterinner burner ring 210 atentrance 214 ofinner burner ring 210 andouter burner ring 220 atinlets 224 ofouter burner ring 220.Venturi mixing tubes 260 can assist with mixing of fuel and air withinentrance 214 ofinner burner ring 210 andinlets 224 ofouter burner ring 220. However, such fuel and air mixture can exitVenturi mixing tubes 260 at a relatively high velocity. Further, a pressure of such fuel and air mixture can increase upon impacting top 212 andcover 222. -
Entrance 214 ofinner burner ring 210 is symmetrically or concentrically positioned relative toexits 216 ofinner burner ring 210 such that the fuel and air mixture can flow uniformly out ofexits 216 ofinner burner ring 210. However,inlets 224 ofouter burner ring 220 are non-symmetrically or non-concentrically positioned relative tooutlets 228 ofouter burner ring 220. Thus, withoutregulator 230 andadditional regulator 250, the fuel and air mixture enteringfuel chamber 226 atinlets 224 can exitoutlets 228adjacent inlets 224 at a higher velocity and flow rate relative tooutlets 228 not positionedadjacent inlets 224. -
Regulator 230 andadditional regulator 250 assist with reducing a velocity and/or flow rate of the fuel and air mixture entering the at least twooutlets 236 ofoutlets 228 and the at least twoother outlets 254 ofoutlets 228, respectively, e.g., proportional to the pressure infuel chamber 226. Thus,regulator 230 andadditional regulator 250 can assist with regulating or controlling the velocity and/or pressure of fuel withinouter burner ring 220 such that fuel and air can exit each outlet ofoutlets 228 at about a uniform pressure and velocity and flames at each outlet ofoutlets 228 can be uniform as well over a range of inlet flows. - This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they include structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
