Definitions

  • the present invention relates to liquid fuel burner appliances, and more specifically to backpacking and camping stoves.
  • Liquid fuel camp stoves and lanterns for camping and outdoor use are well known and are described, for example, in U.S. Pat. No. 3,876,364, which is owned by The Coleman Company, Inc., assignee of the present invention.
  • Liquid fuel which is used in such camp stoves and lanterns may be, for example, COLEMAN brand fuel, white gas, unleaded gasoline, or other liquid fuels.
  • the needle partly blocks the orifice during the lighting cycle and is removed to leave the orifice unblocked during the normal burn cycle.
  • This partial blockage during the lighting cycle causes air to be drawn down the space between the internal and outer conduits of the dip tube from an opening at the upper part of the pressure vessel.
  • a fuel-lean mixture of fuel and air is created to enhance lighting.
  • a fuel-lean mixture is needed at initial lighting, because the fuel in the mixture is not vaporized and thus must be mixed with a lot of air for combustion.
  • the air-fuel mixture then passes to a generator which is connected to the dip tube by the fuel control system.
  • the generator is a metal tube which passes above the burner of the stove into a venturi assembly which is connected to the burner.
  • the generator is heated by the flame of the burner when the burner is operating. Fuel is discharged at high velocity from an orifice or jet at the end of the generator into the venturi where air is aspirated and mixed and fed to the burner with the air/fuel mixture as a combustible mixture for burning.
  • the fuel that travels through the generator is vaporized.
  • the fuel expands and may be supplied in a less lean mixture.
  • the needle may be removed from blocking of the passage.
  • liquid fuel appliances which do not include an instant lighting system require some other means for heating the generator during start-up, for example, liquid priming fuel, or heating paste. In either event, the lighting process is difficult for a user. Often, a user will forget to switch the needle (e.g., by moving the lever) after the lighting process. If liquid priming fuel is used, then the process can often take a minute or more, and results in blackening of the bottom of the stove.
  • a stove having a burner bottom with an integrated trough for catching fuel during a burner lighting stage.
  • the trough may be formed, for example, by a section that is captured between a raised center of the burner bottom and a raised outer annular rim of the burner bottom.
  • a burner top for the stove includes a plate that directs fuel contacting the burner top down into the trough in the burner bottom.
  • This plate may be, for example, a plate having a downward-turned outer annular lip that extends toward the trough.
  • a fuel tip that extends down into a liquid fuel tank for the stove.
  • the fuel tip includes a piston that is moveable to provide a lean air to fuel mixture upon start of the stove, and a less lean air to fuel mixture after the stove is started.
  • a stove in accordance with another embodiment, includes an enclosed pan spaced from a burner.
  • a tube or other conduit extends between the enclosed pan and the burner.
  • a generator feeds into the enclosed pan.
  • a venturi tube may be connected between the closed pan and the generator.
  • the closed pan serves as a reservoir for fuel at a starting of the stove. The pan is heated by the generator so that fuel evaporates and is burned at the burner.
  • FIG. 1 is a side perspective view of a stove in accordance with an embodiment of the invention
  • FIG. 2 is an exploded side perspective view of a burner assembly for the stove in FIG. 1 ;
  • FIG. 3 is a side perspective view of a burner bottom for the burner assembly in FIG. 2 ;
  • FIG. 4 is a sectional view of the burner assembly of FIG. 2 ;

  • FIG. 11 is an alternate embodiment of a stove.
  • FIG. 1 shows a backpacking stove 20 in accordance with an embodiment of the invention.
  • the backpacking stove 20 includes a mushroom-shaped burner 22 connected by a fuel feed line 24 to a liquid fuel tank 26 .
  • the liquid fuel feed line 24 connects to a cleaning needle control valve 27 which in turn is connected to a generator 28 .
  • the generator 28 in a manner known in the art, winds around and over the mushroom-shaped burner 22 so that it may be heated by a flame coming out of the burner.
  • the generator 28 then extends downward to a bottom of the stove 20 and upward in a vertical direction ( FIG. 4 ) into the bottom of the mushroom-shaped burner 22 .
  • a lower heat shield 30 (removed in FIG. 4 so as to show detail) is positioned below the mushroom-shaped burner 22 .
  • a burner bushing 32 which serves as a venturi for the backpacking stove 20 , extends upward through the center of the heat shield 30 .
  • the burner bushing 32 extends slightly through an opening in a burner bottom 34 which is aligned just above the heat shield 30 .
  • a burner top 36 is positioned over the burner bottom 34 .
  • a plate 38 ( FIG. 4 ) having a downwardly turned circumferential outer lip 39 is centered on a bottom side of the burner top 36 and arranged so that the downwardly turned circumferential outer lip 39 extends downward.
  • the plate 38 is connected to or formed integral with the burner top 36 .
  • the lip 39 may be formed in the bottom of the burner top 36 without the use of a plate structure.
  • the burner bottom 34 in the embodiment shown in the drawings includes an outer rim 40 .
  • An annular ridge 42 is positioned just inside of the outer rim.
  • the burner bottom 34 also includes a raised center 44 .
  • a trough 46 is formed between the annular ridge 42 and the raised center 44 .
  • the downwardly turned circumferential outer lip 39 is arranged so that the lip 39 is directed downward toward the trough 46 . The purpose of this arrangement is described below.
  • a fuel tip 50 is provided in accordance with an embodiment of the invention.
  • the fuel tip 50 is attached to an air inlet tube 52 , an end of which is, in a manner known in the art, positioned above the fuel level in the liquid fuel tank 26 when the liquid fuel tank is full.
  • FIG. 6 An exploded perspective view of the fuel tip 50 is shown in FIG. 6 .
  • the fuel tip 50 includes a body 54 and a plug 56 that is threaded into one end of the body 54 .
  • a piston 58 floats within the body 54 , as further described below.
  • a spring 60 is positioned to bias the piston 58 toward the plug 56 .
  • the body 54 includes a center bore 62 .
  • a threaded fuel end 64 is positioned on one end of the center bore 62
  • an outlet 66 is positioned on the opposite end.
  • An air inlet 68 is positioned between the threaded fuel end 64 and the outlet 66 , and enters the bore 62 perpendicular to a longitudinal axis of the bore.
  • the air inlet 68 is attached to the air inlet tube 52 .
  • the outlet 66 is connected to a conduit 70 ( FIG. 1 ) that provides an air and fuel mixture to the fuel feed line 24 , as is further described below.
  • the plug 56 threads into the threaded fuel end 54 .
  • a rear slot 72 is provided on the back of the plug 56 as a tool receiving pattern, for example to receive the end of a screw driver. A different pattern may be used.
  • a front slot 74 is positioned on the opposite end of the plug.
  • the plug 56 includes a bore 76 that extends through its center. The bore includes a narrow opening 78 positioned toward the front (right side in FIG. 7 ) of the bore 76 .
  • the piston 58 includes a front slot 80 .
  • a narrowed portion 81 is formed on the front of the piston 58 so that a shoulder 82 is formed.
  • the spring 60 extends over the narrowed portion 81 and against the shoulder 82 .
  • a stem 84 extends off the rear portion of the piston 58 .
  • the stem 84 includes a narrow portion 86 at the forward end, and a wider portion 88 at the rearward end.
  • the stem 84 and the piston 58 are arranged and configured so that the piston 58 may move longitudinally in the bore 62 of the body 54 . During this movement, the stem 84 moves along the narrow opening 78 of the plug 56 .
  • a stove burner such as the mushroom-shaped burner 22
  • the fuel line such as the fuel feed line 24
  • the backpacking stove 20 includes both the trough 46 in the burner bottom 34 and the novel fuel tip 50 to address this problem.
  • the air in the liquid fuel tank 26 is pressurized, for example by manual pumping of a pump 90 ( FIG. 1 ) in a manner known in the art.
  • This pressurized air (A in FIG. 1 ) is in fluid communication with the air inlet tube 52 , and therefore the air inlet 68 of the body 54 of the fuel tip 50 . Air enters the fuel tip 50 through this air inlet 68 .
  • the back of the plug 56 is in communication with the liquid fuel (F in FIG. 1 ) in the tank, and fuel flows into the fuel tip 50 through the bore 76 in the plug 56 .
  • the spring 60 when the piston 58 is in the position in FIG. 8 , the spring 60 is fully compressed. Thus, the flow of air and fuel around the piston 58 and through the spring 60 is limited, or may be blocked altogether. For this reason, the front slot 80 is provided on the front of the piston 58 . An air-fuel mixture may flow into the front slot 80 and through the center of the compressed spring 60 , and may easily arrive at and flow out of the outlet 66 .
  • the air-fuel mixture that flows to the outlet 66 is very lean.
  • This mixture provided with the wider portion 88 of the stem 84 positioned in the narrow opening 78 is referred to herein as the “start position” fuel mixture.
  • a user pumps the pump 90 to pressurize the fuel tank 26 , turns on the fuel, for example via a valve on the fuel tank (not shown, but known) and lights the mushroom-shaped burner 22 .
  • a valve on the fuel tank not shown, but known
  • the fuel may be a significant amount of fuel in the liquid fuel feed line 24 , causing a very fuel rich mixture to first reach the mushroom-shaped burner 22 .
  • the valve on the fuel tank is opened, fuel that is already in the line 24 is forced through the fuel feed line 24 and the generator 28 by the air pressure from the liquid fuel tank 56 .
  • the quantity of fuel in the line may be minimized by having an obstruction in the line, such as a rubber rod. As the fuel flows rapidly through the generator 28 , and through the burner bushing 32 , the fuel hits the plate 38 .
  • the fuel flows across the plate 38 and outward to the downwardly-turned circumferential outer lip 39 .
  • the fuel then drips downward off the downwardly-turned circumferential outer lip 39 into the trough 46 .
  • Some of the fuel is ignited as it enters the mushroom-shaped burner 22 , and that lit fuel aids in starting of the backpacking stove 20 . This initial flame aids in heating of the generator 28 .
  • Heating of the generator 28 causes vaporization of fuel in the generator.
  • the fuel takes more volume in the generator 28 , and back pressure in the fuel feed line 24 and at the outlet 66 is increased. As this back pressure increases, the pressure equalizes across the piston 58 , and the spring 60 drives the piston backward to the position shown in FIG. 7 .
  • the narrow portion 86 of the stem 84 is aligned with the narrow opening 78 of the plug 56 , and fuel flow through the plug 56 and around the stem 58 is increased.
  • the piston 58 is to the left as is shown in FIG. 7 , the rear portion of the piston engages or is closely situated near the front portion of the plug 56 . Thus, it is possible that the piston 58 may block fuel flow through the plug.
  • the front slot 74 permits fuel to flow through the narrow opening 78 , out through the slot, and around the piston 58 .
  • the narrow portion 86 may be sized appropriately so that this fuel flow may be at a desired rate.
  • the increase in fuel flow results in a richer air-fuel mixture which is fed to the outlet 66 and the fuel feed line 24 during normal operation of the backpacking stove 20 .
  • the fuel within the trough 46 is vaporized by heating of the burner 22 through the flame. Eventually, all fuel is evaporated out of the trough 46 , and combustion occurs only from fuel fed through the fuel feed line 24 . At this point, the backpacking stove 20 is running at normal operating fuel flow.
  • the unique fuel tip 50 provides a number of benefits.
  • the air-fuel mixture is automatically adjusted as a result of back pressure provided by the generator 28 . Therefore, unlike in prior art devices, the user does not have to operate a needle or lever or otherwise manually change operation of the backpacking stove 20 after the initial start of the backpacking stove.
  • the fuel tip 50 may adjust according to conditions. As an example, during windy conditions, the flame may be blown out of direct contact with the generator 28 , so that the generator is no longer adequately heated for vaporization of the fuel. In such a situation, in many prior art stoves, the fuel mixture, because it is no longer vaporized, is too rich, and excess fuel is provided at the burner. A lean fuel mixture must be supplied for recovery, usually by using the starting process, such as the flipping of a lever.
  • the piston 58 moves to the position shown in FIG. 8 when the air pressure on the back of the piston exceeds the biasing force of the spring 60 and the back pressure from the fuel line 24 .
  • the piston 58 moves to the position shown in FIG. 7 when the back pressure from the fuel line 24 and the biasing force of the spring 60 exceeds the air pressure on the back of the piston from the air inlet 68 .
  • a person of ordinary skill may select the spring constant of the spring 60 and may properly arrange the piston 58 so as to provide desired operation of the fuel tip 50 .
  • the fuel tip 50 may be rearranged along with the piston 58 so that operation may be performed without biasing of the spring 60 , for example by providing a free floating piston.
  • the center bore 62 may be rearranged relative to the piston 58 to provide different pressures against the piston.
  • air pressure within the fuel tank 26 is typically at 23 pounds per square inch.
  • the back pressure within the fuel line 24 is slightly less than that amount; for example, the back pressure may be 22 pounds per square inch.
  • the amount of back pressure in the fuel line 24 that is needed to move the piston 58 to the position in FIG. 7 is variable based upon the amount of air pressure in the tank 26 . That is, if the tank is pumped to a higher pressure, more back pressure is needed to move the piston 58 to the position shown in FIG. 7 . However, at initial lighting of the stove 20 , the back pressure is minimal, and thus the piston is moved to the position in FIG. 8 . As the stove gets hotter and back pressure increases, the back pressure eventually is high enough to, along with the spring 60 , overcome the pressure differential to move the piston 58 to the position shown in FIG. 7 .
  • an o-ring 98 may be provided on the stem side of the piston 58 .
  • This o-ring 98 acts as a bumper for the piston 58 when the piston moves to the closed position shown in FIG. 7 .
  • any clicking noise that may be generated by the piston 58 moving against the inside of the valve body may be reduced or eliminated by the cushioning effect of the o-ring 98 .
  • FIG. 9 shows a double burner stove 100 in accordance with an embodiment of the invention.
  • the double burner stove 100 includes a fuel feed line 102 , similar to the fuel feed line 24 , but leading to a fuel manifold 104 .
  • Valves 106 , 108 are provided on opposite sides of the manifold 104 for feeding fuel to separate fuel lines 110 , 112 on opposite sides of the manifold 104 .
  • These fuel lines feed two separate burners 114 , 116 .
  • the fuel tip 50 of the invention permits the double burner stove 100 to be operated. Without such a fuel tip, an attempt to light one of the burners 114 , 116 after the other burner is already operating would result in an overly lean air-fuel mixture at the already running burner and most likely would cause it to go out.
  • the fuel tip 50 permits automatic adjustment for such a situation so that air-fuel mixtures for each of the burners 114 , 116 are maintained as needed. Also, air does not continuously move through the line, which would require continuous pumping.
  • the lack of fuel pressure by the generator for the burner 116 causes the fuel tip 50 to move to the starting position and provide a fuel lean mixture. After the burner 116 is operating, the fuel tip 50 returns to the operating position.
  • the fuel tip 50 operates as described above when a first of the two burners 114 , 116 is lit, or both burners are lit at the same time.
  • FIG. 11 shows an alternate embodiment of a stove 200 .
  • the stove 200 includes a generator 202 , similar to the generator 28 . However, instead of feeding into the bottom of the burner, the generator 202 feeds to a downward facing venturi tube 204 .
  • the venturi tube 204 is attached to the top of an enclosed pan 206 .
  • An upwardly extending burner tube 208 extends from an opposite side of the enclosed pan 206 to a burner 210 .
  • the arrangement of the stove 200 shown in FIG. 11 is advantageous in that the enclosed pan 206 provides a location for fuel to accumulate at the beginning of a starting process.
  • the length of the burner tube 208 spaces this fuel from combustion in the burner 210 , and thus the fuel within the enclosed pan 206 is not used as part of the initial burning process.
  • the fuel that is within the fuel line to the stove (described above) is directed through the venturi tube 204 downward into the enclosed pan 206 .
  • This fuel accumulates in the pan 206 , with some fuel mixing with air to flow upward through the burner tube 208 into the burner 210 .
  • This fuel and air mixture is lit by the user and is typically much leaner than a fuel and air mixture at initial start up, because much of the liquid fuel is maintained within the enclosed pan 206 .
  • the flame from the burner 210 is much hotter, providing faster heating of the generator 202 .
  • the generator 202 then works in conjunction with the fuel tip 50 to provide adequate fuel to the burner 210 .
  • the venturi tube 204 As the generator 202 is heated, the venturi tube 204 , and thus the enclosed pan 206 , are also heated. Each of these items may be made of a thermally conductive material to enhance this process.
  • the fuel that is within the enclosed pan 206 is vaporized by the heat, and mixes with the other fuel in the system. This fuel is eventually burned off, typically within a couple of minutes of lighting the stove.
  • the embodiment of the stove 200 shown in FIG. 11 is a very efficient model for starting. When used with the fuel tip 50 , a user may experience very fast lighting of the stove 200 without having to do anything but pump a fuel bottle, turn on the gas, and light the stove. The stove should be ready for use within a minute or two.
  • the enclosed pan 206 may be positioned in a location that is different from the position shown in FIG. 11 , but is located in the fuel line between the fuel tank 26 and the burner 210 so that it may capture excess fuel in the line but let the proper fuel-air mixture through to the burner.
  • the enclosed pan 206 is heated by the burner during combustion so that liquid fuel trapped in the enclosed pan 206 may be more quickly vaporized.
  • the burner may be thermally connected to the enclosed pan 206 so as to heat the pan through conduction, as shown in FIG. 11 , but the enclosed pan may be alternatively be heated through radiation.
  • Primary heat to the enclosed pan 206 is provided via the generator 202 .
  • the hot gases flowing from the generator 202 aid in vaporization of the fuel in the enclosed pan 202 .
  • Vaporization is slowed a little because the enclosed pan is attached to a number of metal parts, such as the legs for the stove 200 , which dissipate heat.
  • a highly thermally conductive pan (not shown) may be arranged in the enclosed pan. The highly conductive pan would heat faster than the enclosed pan 206 because the increased thermal conductively would cause that part to heat before dissipating heat to other parts of the stove 200 .
  • any structure that is capable of capturing excess fuel in the fuel line between the fuel tank 26 and the burner 210 may be used.
  • the structure is enclosed so that fuel and air flows to the burner without escaping.
  • the arrangement of the stove 200 shown in FIG. 11 may be used in a stove having two burners. Similar to the embodiment shown in FIG. 9 , such a stove would benefit from use of the fuel tip 50 , and would provide an easy-to-light stove that can maintain one or two flames via the operation of the fuel tip 50 .
