FIRE DISPLAY DEVICE AND METHODS

FIELD

The present description relates generally to a fire display device and methods.

BACKGROUND/SUMMARY

A fire pit is a vessel for containing a flame, typically used outdoors, and may be considered a type of fire display device. A torch may also be considered a type of fire display device. Fire display devices may be utilized for an entertaining and theatrical effect in which it may be desirable for the flames to be produced in a manner that is highly visible compared to traditional fire display devices. In some examples, such fire display devices may further be coordinated to an audio input, such as music as part of the entertaining and theatrical effect.

Such fire displays devices present certain challenges. For example, it may be difficult to form flames that are easily seen from further distances where the fire pit is visible to the observer. Further challenges may arise in creating defined ignition events in which multiple gaseous fuel streams are ignited at substantially the same time and in shaping the flames into different shapes for theatrical effect, for example.

Traditional ignition configurations may comprise a pilot light that ignites gaseous fuel close to a burner pan, resulting in flames that are closer to the burner pan, spread out, and relatively low in height. Thus, such traditional ignition configurations result in flames that are difficult to see from further distance visually. Furthermore, traditional ignition configurations ignite gaseous fuel in a manner that creates a whipping effect, where gaseous fuel streams are ignited one after the other rather than igniting multiple gaseous fuel streams at substantially the same time. This whipping effect creates a lagging effect that may be undesirable for theatrical display purposes. Additionally, external factors, such as airflow, may affect the flame of the pilot light, the ignitor, or the gas streams to reduce the size, alter the shape, or increase the whipping effect.

In one example, the issues described above may be addressed by fire display devices and methods that comprise directing at least one stream of flames produced within a center housing at the center of a fire display device vertically above the center housing. Additional gaseous fuel streams may then further be directed towards the at least one stream of flames via gaseous fuel injectors positioned outside of the center housing.

Via the above approach, the resulting flames were found to have a substantially increased height compared to flames generated via traditional configurations. Furthermore, the undesirable whipping effect of traditional configurations is avoided. Thus, highly visible flames may be produced resulting in an enhanced entertainment and theatrical effect.

It should be understood that the summary above is provided to introduce in simplified form a selection of concepts that are further described in the detailed description. It is not meant to identify key or essential features of the claimed subject matter, the scope of which is defined uniquely by the claims that follow the detailed description. Furthermore, the claimed subject matter is not limited to implementations that solve any disadvantages noted above or in any part of this disclosure.

DETAILED DESCRIPTION

The following description relates a fire display device and methods. An example of multiple fire display devices arranged in a display is shown in a system environment of FIG. 1. One or more of the fire display devices may have a configuration as shown in the schematic of FIG. 2 and produce a highly visible flame as shown at FIG. 3 at least in part due to the ignition configuration shown at FIG. 4. FIG. 4 shows an isometric view an ignition configuration of the burner with a housing to enclose pilot light. An additional configuration of the fire pit is shown with the burner from FIG. 4 in FIG. 5A-B that may be in a fire display device of a different shape. FIG. 5A shows a first top view of the burner and how the burner may be fastened to the burner plate. FIG. 5B shows a second top view of the burner without a housing and an exposed pilot light.

The fire display device may be referred to as a fire pit. The fire pit may serve as décor and lighting. In large spaces, it is often desirable to have multiple fire pits and, in some cases, one or more additional fire devices such as fire pits on display. Such fire devices may be coordinated with an input, such as an audio input, to provide bursts of flame for an entertaining and theatrical effect.

For purposes of discussion, the below figures are described collectively. Thus, similar elements may be labeled similarly and may not be re-introduced. FIGS. 3-5B are shown approximately to scale.

Turning first to FIG. 1, it shows a system environment 100, according to one or more examples of the present disclosure. The system environment 100 is shown in a large warehouse space in the present disclosure. In other examples, however, the system environment 100 may instead be an outdoor environment, such as a backyard. The system environment 100 comprises fire devices including a plurality of torches 102a, 102b, 102c, 102d (also referred to as torches 102). Though there are four torches shown in the example at FIG. 1, it is noted that additional torches or fewer torches may be included in the system without departing from the scope of the disclosure.

In addition to the torches 102, the system environment 100 comprises additional fire devices including a first fire pit 104a, a second fire pit 104b, and a third fire pit 104c (also referred to as fire pits 104). As with the torches 102, there may be additional fire pits or fewer fire pits included in the system, in at least one example. The torches 102 and the fire pits 104 together may form a fire display 101. Each of the fire pits 104 and torches 102 may include a fire device controller, wireless receiver, input panel, and a battery as discussed further below with respect to FIG. 2. The fire device controller and audio input may receive signals from a hub 110.

The hub 110 is a controller that comprises a processor with instructions stored in non-transitory memory that, when executed, sends control signals to control one or more of the torches 102 and the fire pits 104. For example, the control signals sent from the hub 110 may be received at fire device controllers and audio inputs of the respective torches 102 and fire pits 104. Each of the torches 102 and fire pits 104 additionally comprises an ignitor and at least one electric valve positioned therein that is configured to adjust an amount of fuel provided for ignition of the respective torch or fire pit.

Responsive to receiving control signals from their respective fire device controllers, the torches 102 and fire pits 104 may then actuate at least one of the electric valve and the ignitor for each of the respective torches 102 and fire pits 104. Via such actuation, a flame size and height may be controlled for the torches 102 and fire pits 104.

The control signals are sent from the hub 110 to one or more of the torches 102 in response to the processor of the hub 110 receiving input signals. The control signals may further be sent from the hub 110 to one or more of the fire pits 104 responsive to such input signals. In at least one example, the processor of the hub 110 receives input signals via one or more of a wireless receiver of the hub 110, a hardwired connection of the hub 110, and a user interface integrated into the hub 110 itself, where the user interface comprises one or more user input devices (e.g., buttons, dials, a touch screen) to receive the input signal.

In at least one example, the hub 110 may be a mobile device of a user, such as a cellular telephone or a laptop of the user. In such examples, it is noted that an application of the mobile device may be used to control the torches 102 and fire pits 104. That is, when the hub 110 is a mobile device, an application of the mobile device may provide a display via the mobile device and receive input signals via a user interface of the mobile device (e.g., buttons, a touch screen).

The input signals received at the hub 110 may include a mode selection received at the hub 110. Additionally or alternatively, a mode election may be received at the input panels of the respective torches 102 and fire display devices 204. For example, the mode selection may include selection of a traditional mode or an audio mode. In the traditional mode, the torches 102 and fire pits 104 are operated with their respective electric valves maintained at a predetermined base position. At the predetermined base position, the electric valves of the torches 102 and the fire pits 104 are at least partially open and allow fuel to flow to their respective burners. If the electric valve of any of the torches 102 and fire pits 104 being controlled in the traditional mode is not at the base position when the traditional mode is selected, then the electric valve is first adjusted to the predetermined base position and maintained in the base position for a duration of the traditional mode. Due to the maintained position of the electric valve, a steady flame size and height is maintained in the traditional mode.

In the audio mode, the torches 102 and fire pits 104 are operated with their respective electric valves being varied in coordination to an audio input, such as music. Thus, responsive to receiving a user input selecting the audio torch mode and further receiving the audio input, the hub 110 may send control signals to the audio input devices of torches 102 and fire pits 104 based on the audio input.

In particular, the hub 110 may send control signals to adjust respective electric valves of the torches 102 and the fire pits 104 in coordination with the audio input. It is noted that the audio input may be received at each fire display device. For example, the audio input may be received at the hub 110 via wirelessly streaming the audio input to the hub 110 via a mobile device or other personal computing device. In such examples, a wireless receiver of the hub 110 may receive the audio input. As another example, the audio input may be received at the hub 110 via an aux input or other wired audio input. In such examples, a mobile device or other personal computing device may provide the audio input to the hub 110 via such an aux input or other wired audio input.

The electric valve may be adjusted to positions more open than the base position of the traditional mode while in the audio mode, based on the audio input. Additionally, the electric valve may be adjusted to positions that are less open than the base position of the traditional mode while in the audio mode, based on the audio input. In this way, flame bursts and decreases in flame size may be created for the fire display. Thus, in contrast to the traditional mode, the torches 102 and fire pits 104 produce flame sizes and heights that are varied throughout the audio mode in coordination with the audio input.

In at least one example, a flame boost mode may further be available, in which a maximum fuel flow is provided to a burner. In some examples, the flame boost mode may be used for purposes of heating an accessory, such as a griddle or grill attachment. The flame boost mode may also be used for purposes of producing a maximum flame height and size, which may be of interest for lighting or theatrical effect, for example. In the flame boost mode, the respective electric valve of the torches 102 or fire pits 104 is actuated to a wide open position. In at least one example, the flame boost mode may further include a mechanical valve providing fuel to the burner to be manually adjusted to a wide open position, in addition to the electric valve being adjusted to the wide open position.

In examples where the flame boost mode is available, it is noted that the wide open position of the electric valve is more open than the base position for the traditional mode. That is, in examples where the fire devices include the flame boost mode, the flame boost mode creates a maximum flame height and size, which is larger than the flame height and size when operating in the traditional mode.

In at least one example, hub 110 allows for there to be separate control of the torches 102 and the fire pits 104. In separate control examples, it is noted that the mode selections for each of the fire pits 104 and the torches 102 may be made individually set. Thus, each of the torches 102 and each of the fire pits 104 is able to have its own mode selected and individually controlled via the hub 110 and/or via the input panel at each of the torches 102 and fire pits 104. In at least on example, it is noted that a mode selected at the input panel may take priority to a mode selected at the hub. For example, if the hub 110 receives a request to operate the torches 102 and fire pits 104 in an audio mode but the input panel of one of the fire pits 104 is set to the traditional mode, then the fire pit set to the traditional mode will be operated in the traditional mode even though the hub 110 is outputting an audio mode control signal. This allows for local control at the input panel of the torches 102 and the fire pits 104 to take priority for a particular torch or fire pit.

Additionally, or alternatively, the hub 110 may control the torches 102 and the fire pits 104 collectively. In collective control examples, the hub 110 may control the torches 102 and the fire pits 104 all together to be in the same mode. For example, in collective control examples, selection of the traditional mode may result in all of the torches 102 and the fire pits 104 being set to the traditional mode. Further, in the collective control examples, selection of the audio mode may result in all of the torches 102 and the fire pits 104 being set to the audio mode. As to selection of the flame boost mode, in the collective control examples, selection of the flame boost mode may result in all of the torches 102 and the fire pits 104 being controlled to have their respective electric valves in a wide open position.

Further, the hub 110 may additionally or alternatively control the torches 102 and fire pits 104 in sub-groups. In such sub-group control, sub-groups of the torches 102 and/or the fire pits 104 may be formed for control of the sub-group to be the same. For example, in sub-group control, the hub 110 may control the torches 102 together as an all torches sub-group and may control the fire pits 104 together as an all fire pits sub-group. Thus, in this example, the mode for the all torches sub-group being selected as the traditional mode would result in the torches 102 all being set to the traditional mode. Alternatively, the mode for the all torches sub-group being selected as the audio mode would result in the torches 102 all being set to the audio mode. Similarly, in this example, the mode for the all fire pits sub-group being selected as the traditional mode would result in the fire pits 104 all being set to the traditional mode. Or, alternatively, the mode for the all fire pits sub-group being selected as the audio mode would result in the fire pits 104 all being set to the audio mode.

In another sub-group control example, the hub 110 may control a portion of the torches 102 as a first torch sub-group, another portion of the torches 102 as second torch sub-group, a portion of the fire pits 104 as a first fire pit sub-group, and another portion of the fire pits 104 as a second fire pit sub-group. Moreover, a sub-group may contain both torches 102 and fire pits 104, in at least one example.

It is noted that if selection of any of the traditional mode, audio mode, and flame boost mode is also determined to initiate ignition at one or more of the torches 102 and fire pits 104, then the hub 110 may further send a control signal to activate respective ignitors of such torches and fire pits.

As described above, a fire display including multiple fire display devices may use multiple fuel containers, one for each fire display device. Further, the multiple fire display devices may not be coordinated devices able to create a desired effect, especially when the intensity of flame at each fire display device may be controlled individually or as a group. A fire display device including a controller and audio input as shown in FIG. 2 below may allow a coordinated display between multiple display devices and a common fuel line may allow multiple devices to be fueled by a single fuel container.

Looking briefly to FIG. 2, FIG. 2 shows an example diagram 250 of the ignition configuration for one or more of the fire display devices 204. Fire display device 204 may include a fuel passage 252 fluidically coupled to a pilot light 254 and a plurality of fuel injection ports 256 via a mechanical valve 258 and an electronic valve 260. Fire display device 204 may be the same or similar to one of the fire pits 104 shown in FIG. 1.

Fuel passage 252, also referred to herein as a split fuel passage, may include an introductory portion 252a which may be fluidically coupled to a connector 264 positioned external to a housing 262 of fire display device 204. Connector 264 may be a quick connect coupled to a fuel source 202 via a fuel line 214. The fuel source 202 may be a gaseous fuel source, such as a propane or natural gas fuel source. In one example, connector 264 may be position at a bottom side of the fire display device. Gaseous fuel traveling from the fuel source 202 via fuel line 214 and connector 264 further flows through introductory portion 252a towards pilot light 254, and fuel injection ports 256 may reach a first junction 266a which may split fuel passage 252 into a mechanical portion 252b and an electric portion 252c. Mechanical portion 252b may further split at second junction 266b to include a pilot portion 252d fluidically coupled to pilot light 254. Mechanical portion 252b and electric portion 252c may rejoin at third junction 266c to become fuel injection portion 252e which is fluidically coupled to the plurality of fuel injection ports 256.

Mechanical valve 258 may be configured to control a flow of gaseous fuel entering fuel injection portion 252e from mechanical portion 252b. In one example, mechanical valve 258 may be configured at mechanical portion 252b to also control the flow of gaseous fuel to pilot light 254. Mechanical valve 258 may be physically coupled to and controlled by user input device 268 positioned outside of housing 262. User input device 268 may be located at input panel 223 as discussed above with respect to FIG. 2. For example, the user input device 268 may be a dial, where turning the dial a first direction may adjust the mechanical valve 258 to a more open position and turning the dial a second direction may adjust the mechanical valve 258 to a more closed position. Thus, via the user input device 268, a user is able to set a base amount of fuel allowed to flow through the mechanical valve 258 into fuel injection portion 252e.

Electronic valve 260 may be configured to control a flow of gaseous fuel from electric portion 252c into fuel injection portion 252e. Electronic valve 260 may be physically and communicatively coupled to control module 218. Control module 218 may include controller 222, battery 224, and wireless receiver 220 with respect to FIG. 2. For example, control module 218 may receive a wireless signal 272 with instructions to control a position of electronic valve 260 to provide flame bursts synchronized with an audio input. In this way, mechanical valve 258 may control a base amount of fuel when fire display device 204 is operated in a traditional mode while electronic valve 260 may be actuated by control module 218 to provide additional fuel resulting in flame bursts coordinated by an audio signal when in audio mode.

In an alternate embodiment, mechanical valve 258 may be controlled electronically by physically and communicatively coupling to control module 218. In this way, mechanical valve 258 may be controlled by wireless signal 272 sent to control module 218 from the control hub as well as a signal generated by user input device 268.

Gaseous fuel reaching pilot light 254 may be ignited by a spark generated by ignitor 274. Ignitor 274 may be physically and communicatively coupled to control module 218 and may be actuated in response to a command from control module 218 and/or input panel 223. Control module 218 may receive a signal from user input device 268 and/or a wireless signal 272 commanding ignition of pilot light 254.

Once ignited, the pilot light may ignite the gaseous fuel flowing from a plurality of fuel injection ports 256 as controlled by both mechanical valve 258 and electronic valve 260. Additional details regarding plurality of fuel injection ports 256 and pilot light 254 may be discussed in further detail below with respect to FIG. 4-5B.

The fuel entering the fire display device 204 as described above may be sourced from a common fuel line which may be divided by a plurality of pressure junctions to deliver fuel to a plurality of fire display devices

Turning to FIG. 3, a fire pit 300 in operation is shown, according to one or more examples of the present disclosure. The fire pit 300 may be the same or similar to the fire pits shown in FIG. 1 and fire pit 300 may comprise an ignition configuration as shown in FIG. 2. For reference, axes 301 are further included in FIG. 3-6. Axes 301 are provided for comparison between views shown. The reference axes 301 indicate a y-axis, an x-axis, and a z-axis. In one example, the z-axis may be parallel with a direction of gravity and the x-y plane may be parallel with a horizontal plane that the fire pit 300 may rest upon.

As seen in FIG. 3, the fire pit 300 produces a flame 306 in the form of a burst above the fire pit 300. The flame 306 may be set to pulsate to music, a rhythm, or as part of a programmed display included in the non-transitory memory of a controller (e.g., control module 218) of the fire pit 300. The flame 306 is above the enclosure 308 along the z-axis.

For the example shown in FIG. 3, the enclosure is shown rounded in shape, though it is noted that other shapes for the enclosure 308 may be possible. The enclosure 308 of fire pit 300 may comprise a material resistant to flammability or deformation from high temperatures, such as ceramic or nylon glass. The enclosure 308 may further house the control module 218 as well as the one or more of the other ignition configuration components shown within housing 262 in FIG. 2.

Enclosure 308 comprises a burner bed 320 of a first diameter 322 at the top of the enclosure 308 and fire pit 300 along the z-axis. The burner bed 320 is a concave depression that extends into the enclosure 308 down along the z-axis towards a base 324 of the enclosure 308. The enclosure 308 further comprises a base 324 of a second diameter 326. The enclosure 308 may further include a third diameter 328, where the third diameter 328 is a maximum diameter of the enclosure 308, and where the third diameter 328 is greater than both the first diameter 322 of the burner bed 320 and the second diameter 326 of the base 324. The base 324 has a predetermined minimum diameter in the second diameter relative to the first diameter 322 and the third diameter 328 of the enclosure 308. The diameter of the enclosure 308 above the third diameter gradually decreases towards the first diameter 322 in the upward direction along the z-axis. The diameter of the enclosure 308 below the third diameter 328 gradually decreases to the second diameter 326 in the downward direction along the z-axis. However, it is to be appreciated that the geometry of the enclosure 308 and burner bed 320 may be non-limiting, and other embodiments with different geometries have been contemplated and considered.

As illustrated in FIG. 3, the burner bed 320 may support burner 304. The burner 304 may be circular and positioned such that it is substantially centered on a top surface of the enclosure 308. The burner 304 may further be facing upward, away from the base 324. Therein, the z-axis or a line parallel to the z axis may be normal to the burner 304. When the fire pit 300 is operating, the burner 304 produces the flame 306.

FIG. 3 also shows a fuel hose 312 may be coupled to the fire pit 300. The fuel hose 312 may be fluidically coupled and sealed to a fuel source 302. The fuel source may comprise a gaseous fuel, such as propane, and may be the same or a similar fuel source as fuel source 202 shown in FIG. 2. The fuel source may supply fuel to the fire pit 300 through the fuel hose 312. The fuel hose 312 may have a plurality of connection points for a plurality of fire pits 300.

FIG. 3 shows the burner 304 may comprise a burner pan 330 and a single or plurality of rings 332 and a housing 336, where the rings 332 may be concentric and configured as concentric rings about the housing 336. As an example, the housing 336 may be cylindrical in shape. Though a single ring 332 is shown, it is noted that there may be a plurality of rings without departing from the scope of the present disclosure. It is also noted that at least one ring of the rings 332 may couple the burner pan 330. The burner pan 330 may also be referred to herein as a burner plate. The burner pan 330 may be positioned above the burner bed 320 along the z-axis, where the burner pan 330 rests upon and may be supported by the burner bed 320. The rings 332 may further rest upon and be supported by the burner pan 330 and burner bed 320. In at least one example, the rings 332 may be coupled to the burner pan 330.

The burner pan 330 may be used to deflect thermal energy and may also reflect light from the flame 306, therein increasing the brightness. The burner pan 330 may be made of a reflective metal, such as stainless steel, in one or more examples. For the example shown in FIG. 3, the burner pan 330 may deflect and distribute thermal energy around the burner 304. The burner pan 330 in FIG. 3 may also deflect thermal energy toward the flame 306. For the example shown in FIG. 3, the burner pan 330 may be approximately circular in shape. However, it is to be appreciated that the shape of the burner pan 330 may be non-limiting, and other embodiments with different geometries have been contemplated and considered. It is also to be appreciated that the shape of the burner pan 330 may be dependent on the geometry of the burner bed 320.

The rings 332 are concentric and tubular rings fluidically coupled to the fuel source 202 and configured to supply fuel to the flame 306 shown in FIG. 3 for ignition via a pilot light (e.g., pilot light 254). Though the pilot light is not visible in FIG. 3, such a pilot light may be housed within the center housing 336. The rings 332 may comprise a heat resistant material such as a metal, including stainless steel, in one or more examples. The rings 332 may further comprise a plurality of fuel injection ports (e.g., fuel injection ports 256) configured to direct gaseous fuel flowed through the rings 332 towards a center of the rings 332. The center housing 336 may comprise a plurality of apertures that may act as fuel injection ports and/or as apertures for flame streams. The gaseous fuel flowed to the center of the rings 332 and center housing 336 via the fuel injection ports are ignited via the pilot light to produce flame 306. Further details as to the burner 304 are shown in FIG. 4-5B.

Flame 306 may be suspended above the rings 332 at a threshold distance. In one or more examples, the threshold distance may be a predetermined distance from the fuel injectors, such as fuel injection ports 256. Flame 306 may be referred to as a ghost flame. Wherein, the fuel supplied to the flame has an unignited portion of fuel at a set distance 334, e.g. the threshold distance, from the fuel injection ports 256. The fuel supplied may be ignited at a focal point, (e.g., focal point 440 of FIG. 4). The distance 334 of flame 306 above the fire pit 300, allows flame 306 to be less obscured to an observer by the depression of the burner bed 320 and features of the burner 304, such as the rings 332. The ghost flame may be discussed in further detail herein below.

FIG. 3 also shows electricity may be supplied through an electrical cord 314 electrically coupled to the fire pit 300. Electricity may be used power the control module 218 and adjust valves, such as the electronic valve 260, in the fire pit 300 so the flame 306 may pulsate to music. Electricity may also be used to power additional components of the control module 218, including electronics and display interfaces. However, electricity may also be delivered from a battery housed within the fire pit 300 and enclosure 308.

Turning to FIG. 4, it shows a detailed view of a burner 400. In at least one example, burner 400 may be the same or similar to the burner 304 shown in FIG. 3.

FIG. 4 shows the rings 332 of burner 400 may comprise a first ring 402. For the example in FIG. 4 there may be a single ring in the form of the first ring 402; however, there may be a plurality of rings with one or more rings that are circumferentially surrounded by or circumferentially surround the first ring 402. In the center of and circumferentially surrounded by the first ring 402 is a center housing 406 that may be the same or similar to center housing 336. It is noted that the first ring 402 is a concentric ring. FIG. 4 shows the center housing 406 may be connected to the ring 402 through a plurality of first spokes 410. FIG. 4 shows the center housing 406 may be connected to the first ring 402 through a plurality of first spokes 410. The rings 332, the center housing 406, the plurality of first spokes 410 may be fluidically coupled to one another and to a fuel source (e.g., fuel source 202). Wherein, tubes fluidically coupled to the plurality of spokes 410 and within the center housing 406 may extend through at least one opening in the burner pan 330 to fluidically couple a portion of a fuel passage, such as the fuel injection portion 252e of split fuel passage 252. In this way, the burner 304 is configured to flow gaseous fuel from the fuel source and through the burner ring 332, the center housing 406, and the plurality of first spokes 410. It is noted that there may only be one burner ring, in at least one example.

A center axis 412 parallel with the y-axis may be centered on the center housing 406, and circumferentially surrounded by the burner rings 332. The first spokes 410 may be aligned as to extend toward and be equidistant from the center axis 412.

The center housing 406 may be comprised of a wall 416 and a plate 418. The wall 416 may be cylindrical and circumferentially surround the center axis 412, forming a perimeter for the center housing 406. The plate 418, which may be a central plate as shown in FIG. 4, may be approximately circular and coplanar with a plane parallel with a plane formed by the y and x axes. However, it is to be appreciated that the shape of the wall 416 and plate 418 of the housing may be non-limiting, and other configurations may be used. The plate 418 may be located on top of and may couple to the wall 416. The plate 418 has a first aperture 420 and a second aperture 422 fluidically coupled to components of the center housing 406 and fuel passage, such the fuel injection portion 252e of split fuel passage 252, to the exterior of the center housing 406. The plate 418 may also have an overhang 424 that extends past the circumference of wall 416.

FIG. 4 shows the burner may comprise a plurality of fuel injection ports (e.g., fuel the fuel injection ports 256 of FIG. 2 or similar fuel injection ports) located on the rings 332 for distributing fuel to a focal point 440 for ignition. The fuel injection ports may comprise a plurality of ring fuel injectors 438 located on the ring 402 and spoke fuel injectors 434 located on the first spokes 410. Additionally, the first and second apertures 420, 422 may direct fuel toward the focal point 440.

The focal point 440 may be vertically above the concentric burner rings 332, the center housing 406, and the fuel injection ports 256. The focal point 440 may be located on the center axis 412. In at least one example, the focal point 440 may be directly above the center housing 406. By angling all of the fuel injection ports 256 to inject gaseous fuel to the focal point 440, multiple gaseous fuel streams from each of the fuel injection ports 256 may converge at the focal point 440 and be ignited by directing the pilot light flame to ignite fuel at the focal point 440. Such convergence and ignition of the gaseous fuel at the focal point 440 may result in particularly tall flames. In contrast, previous burners have been concerned with providing flames that are spread out with respect to the y and x axes, rather flames that are tall with respect to the z-axis.

The focal point 440 may be positioned above the center housing 406 at a distance 443. For one or more examples distance 443 may be the same or similar to distance 334 of FIG. 3. The length of distance 443 may be parallel with the z-axis and the center axis 412. Parallel with the distance 443 are first path 442a and a second path 442b that fuel may be injected on. The first aperture 420 and second aperture 422 may inject fuel toward the focal point 440 along the first path 442a and the second fuel injection path 442b.

The spoke fuel injectors 434 may be located on the top of first spokes 410 of the rings 332 with respect to the z-axis in FIG. 4.

The ring fuel injectors 438 may be located on the top of the ring 402 of the rings 332 with respect to the z-axis. The plurality of spoke fuel injectors 434 and ring fuel injectors 438 may be angled to inject gaseous fuel towards the focal point 440. The plurality of ring fuel injectors 438 may form a first group of fuel injection ports. FIG. 4 shows the spoke fuel injectors 434 are located at approximately equidistant positions along the spokes 410. Likewise, the ring fuel injectors 438 are located at approximately equidistant positions along the circumference of ring 402.

The fuel injectors ports, including the spoke fuel injectors 434 and ring fuel injectors 438 may be configured such that a fuel injection path of each of these fuel injection ports intersects with the focal point 440. An example of a third path 450 to inject fuel extends from a fuel injector 438 at angle 452 from a line 454 approximately parallel with the y axis. There may be a plurality of fuel injection paths similar to path 450 extending from the ring fuel injectors 438 at angles similar to angle 452. There may be a plurality of fuel injection paths similar to path 450 of a different length extending from spoke fuel injectors 434 at a different angle than angle 452.

The fuel transport components within the center housing 406 shown in FIG. 4 are fluidically coupled to the fuel injection portion of a split fuel passage. For example, the center housing 406 may be fluidically coupled to a fuel injection port that is similar to or the same as the fuel injection portion 252e of the split fuel passage 252 shown in FIG. 2. Therein, components in the center housing 406 may fluidically couple the burner rings 332 to the fuel injection portion 252e of the split fuel passage 252. The plurality of first spokes 410 may fluidically couple the fuel transport components in the center housing 406 to the first ring 402. The burner rings 332 in FIG. 4 may fluidically couple the spoke fuel injectors 434 and the ring fuel injectors 438 to the fuel injection portion 252e of the split fuel passage 252. Additionally, the first and second apertures 420, 422 fluidically couple to the pilot portion 252d similar to the pilot light 254.

A pilot light, the same or similar to the pilot light 254, may ignite fuel within the center housing 406. The first and/or second apertures 420, 422 with a pilot light in the center housing 406 may inject fuel and ignite fuel to create a single or plurality of pilot light flames. The pilot light flames may be isolated from sources of fuel that are not ignited through the first or second apertures 420, 422. A pilot light flame may be ignited by an ignitor similar to ignitor 274 located in the center housing 406. The ignitor may be open to the first and/or second apertures 420, 422, therein allowing a pilot light flame to exit the first and/or second apertures 420, 422 in the form of flame streams. The ignitor 274, may be a device that produces a spark to ignite fuel exiting the pilot light and the first and/or second apertures 420, 422 to form corresponding flame streams. For one example a pilot light flame may ignite and extend from the first aperture 420 along the first path 442a to the focal point in the form of a first flame stream. For this example, the pilot light flame may ignite fuel directed toward the focal point 440 creating a flame above the center housing 406 with respect to the z-axis. For another example a pilot light flame may ignite and extend from the second aperture 422 along the second path 442b to the focal point 440 in the form of a second flame stream. For this example, the pilot light flame may ignite fuel directed toward the focal point 440 creating a flame above the center housing 406 with respect to the z-axis. For another example, a pilot light flame may ignite and extend from the first aperture 420 along the first path 442a and second aperture 422 along the second path 442b to the focal point 440. For this example, the pilot light flames may ignite fuel directed toward the focal point 440 creating a flame above the center housing 406 with respect to the z-axis. For these examples a single or a plurality of pilot light flames may extend the distance 443 to the focal point 440. A flame, such as flame 306, may be ignited and generated at focal point 440 by the pilot light flame from first aperture 420 and/or second aperture 422. In at least one example, the ignitor 274 may instead be configured to directly ignite fuel flowed through one or more of the first aperture 420 and the second aperture 422.

In at least one example, one or more of the fuel injectors 434 and 438 may be configured to inject the gaseous fuel at greater than a threshold rate, such that a ghost flame effect is created. The ghost flame effect is an effect where the flame 306 appears to be suspended a distance away from the fuel injectors 434, 438 and plate 418 of the center housing 406. For example, where the flame 306 appears to be suspended at a distance 443 along the first and second paths 442a, 442b above the center housing 406. This is due to a first portion of the gaseous fuel streams not being ignited (also referred to herein as the unignited portion) and a second portion of the gaseous fuel stream being ignited (also referred to herein as the ignited portion). The unignited portion of the fuel streams extends from the respective one or more fuel injectors 434, 438 to the ignited portion of the gaseous fuel stream between the one or more of fuel injectors 434, 438. In particular, if the one or more fuel injectors 434, 438 are injecting gaseous fuel at greater rate than the threshold rate, a pilot light flame is unable to ignite a portion of the gaseous fuel streams. The unignited portion of the gaseous fuel streams extends from the one or more of fuel injectors 434, 438 for a distance that may be a predetermined distance along the fuel injection paths, wherein the gaseous fuel may be injected at a rate to provide the predetermined distance for the unignited portion of the gaseous fuel stream. Thus, should the flame ignited by a pilot light flame be referred to as a ghost flame, fuel for the ghost flame has an unignited portion for at least a threshold distance, (e.g. a distance along the fuel injection paths, such as first and second paths 442a, 442b and third path 450), from fuel injectors 434, 438 and first and second apertures 420, 422. In one or more examples, it is noted that the threshold distance of the fuel injection paths to the focal point 440 may be a predetermined distance. For one example, the threshold distance above the center housing 406 along the first and second paths 442a, 442b may be two inches to three inches. For this example, the distance of other fuel injection paths from fuel injectors 434 and 438, such as path 450, may be greater than three inches. In other examples the distance of other fuel injection paths of fuel injectors 434 and 438, such as path 450, or paths 442a, 442b from apertures 420, 422, respectively, may be greater than three inches. If the pilot light flame were positioned too close to the fuel injectors 434 and 438 or apertures 420, 422 it is noted that the floating appearance of the ghost flame may be prevented.

In FIG. 4, burner pan 330 may be configured to cover a top portion of the fire display device. Components of the burner rings 332 and center housing 406 may all extend through and above burner pan 330 along the z-axis. At least one burner ring may be coupled to the burner pan 330 or a similar burner plate. The burner pan 330 may include a plurality of first openings 458 which help to ensure adequate air flow for the flame. For other configurations, the burner pan 330 may have at least one opening similar to first openings 458. The center housing 406 may also have a plurality of second openings 460 located on the wall 416. For other configurations, the center housing 406 may have at least one opening similar to second openings 460.

For the example in FIG. 4, the electronic valve 260 and the mechanical valve 258 shown in FIG. 2 are shut to the fuel injection portion 252e and the center housing 406 so that the fuel injection ports 256 may be shut off and not delivering fuel to the focal point 440. For this example, fuel may not be delivered to or through the fuel injectors 434, 438. Additionally, fuel the mechanical valve 258 shown in FIG. 2 may be shut to the pilot portion 252d so the pilot light 254 may not deliver and ignite fuel to the focal point 440. For this example, fuel may not be delivered to or through the first or second apertures 420, 422.

However, for another example, if valve 258 is open to the first and second apertures 420, 422, gaseous fuel may be ejected along the first and second paths 442a, 442b, respectively. For this example, a pilot light and an ignitor in the center housing 406 may be used create a single or a plurality of pilot light flames. For another or the same example, the electronic valve 260 and mechanical valve 258 may be open to the fuel injection portion 252e and the center housing 406. For this example, fuel may be delivered to or through the fuel injectors 434, 438 to the focal point 440 along fuel injection paths, such as the third path 450. For this example, a similar quantity fuel may be dispensed to focal point 440 as the quantity dispensed in FIG. 3. Thus, the flames produced by ignition of fuel with the pilot light flame from the first and/or second apertures 420, 422 in FIG. 4 may similar in size and brightness to the flame 306 in FIG. 3.

Turning to FIG. 5A, an example fire pit 500 is shown from a first top view 502. For the example shown in FIG. 5A, the fire pit 500 may be a rectangular and of a different shape from fire pit 300 with different external components. For this example, the fire pit 500 may have burner pan 510 that is rectangular that a burner 504 may be seated above. For this example, the burner pan 510 may cover portions of the walls 506 of fire pit 500 facing toward the burner 504. For other examples, the fire pit 500 may be the same or similar to fire pit 300 with burner pan 510 the same or similar to burner pan 330.

The burner 504 may be the same or similar to burner 304 and/or burner 400. The center housing 406 of burner 504 may be coupled to the burner pan 510 and fire pit 500 via a plurality of first supports 512 and first fasteners 522. Similarly, the ring 402 may be coupled to the burner pan 510 and fire pit 500 via a plurality of second supports 514 and second fasteners 524. The first and second supports 512, 514 may support and allow the center housing 406 and ring 402, respectively, to be seated upon the burner pan 510. Each of the first and second supports 512, 514 has a hole that may correspond with a hole in the burner pan 510 and fire pit 500. When the holes in the first and second supports 512, 514 and corresponding holes, such as holes 532 in FIG. 5B, in burner pan and fire pit 500 are aligned, wherein corresponding holes circumferentially surround a line parallel with the z-axis, the first and second fasteners 522, 524 may be threaded through the holes. The first fasteners 522 may be threaded through holes in the first supports 512 and into the corresponding holes in the burner pan 510 to couple center housing 406 to the fire pit 500. The second fasteners 524 may be threaded through holes in the second supports 514 and into the corresponding holes in the burner pan 510 to couple the ring 402 to the fire pit 500. The first fasteners 522 and second fasteners 524 may be the same type of fasteners. However, it is to be appreciated that for other examples first and second fasteners 522, 524 may be different types of fasteners with different threading, diameters, and shapes. For these examples the holes in the first and second supports 512, 514, and their respective corresponding holes in the burner pan 510, may be have different threading and diameters from one another. The arrangements described above allows for the burner 504 to be detachable and modular with other compatible fire pits or other fire display devices.

Turning to FIG. 5B, the example fire pit 500 is shown from a second top view 530 closer to the burner 504, wherein the center housing 406 may be decoupled and removed from the burner 504 and burner pan 510. The removal of the center housing 406 exposes a plurality of holes 532 in the burner pan 510 used to fasten the first supports 512 to the burner pan 510 via the first fasteners 522. Additionally, the removal of the center housing 406 exposes a center post 534, an ignitor 536, and a pilot light 538 that may be enclosed by the center housing 406.

The center post 534 is fluidically coupled to the fuel injection portion of a split fuel passage. For example, center post 534 may be fluidically coupled to a fuel injection port that is similar to or the same as the fuel injection portion 252e of the split fuel passage 252 shown in FIG. 2. The center post 534 may fluidically couple the rings 332 to the fuel injection portion 252e of the split fuel passage 252. For the example shown in FIG. 5B, the plurality of spokes 410 fluidically couple the center post 534 to the ring 402, wherein the spokes 410 are fluidically coupled to the center post 534 via coupling, such as welding to the wall 542. The spoke fuel injectors 434 and inner ring fuel injectors 438 may therein be coupled to the fuel injection portion 252e of the split fuel passage 252 via the center post 534 and rings 332.

The center post 534 may be formed of a top surface 540 and a wall 542. The top surface 540 that may be circular and located at the top of the center post 534. The wall 542 may be cylindrical, circumferentially surround the center axis 412, and support the top surface 540. The wall 542 may form a perimeter for the center post 534. The top surface 540 may be approximately circular and coplanar with a plane parallel with a plane formed by the y and x axes. However, it is to be appreciated that the shape of the wall 542 and top surface 540 of the center post 534 may be non-limiting, and other configurations may be used. The top surface 540 may be located on top of and may be formed from the wall 542.

The center post 534 may comprise two openings used for injecting fuel: a first opening 544a and a second opening 544b. The first opening 544a and second opening 544b may also be referred to herein as twin tail injectors. The twin tail injectors are configured to provide two flame streams in a twin tail formation. The twin tail formation includes two similarly shaped flame streams. In this example, the twin tail formation comprises two substantially parallel flame streams that are flowed through the center housing 406 and extend vertically upward above the center housing 406.

The areas of first opening 544a and second opening 544b may be on a plane approximately parallel with and overlap with the areas of the first aperture 420 and second aperture 422, respectively, in the center housing 406 of FIG. 4. The first opening 544a may inject a first fuel stream along a first path 442a through the first aperture 420, and the second opening 544b may inject a second fuel stream along a second path 442b through the second aperture 422.

The first opening 544a and second opening 544b may have similar or smaller diameter compared to an opening 550 and opening 552 on each of the spoke fuel injectors 434 and ring fuel injectors 438, respectively. Therein, gaseous fuel may be passed through the first opening 544a and second opening 544b at similar or higher pressures compared to gaseous fuel injected from the spoke fuel injectors 434 and ring fuel injectors 438, respectively. The diameters of each of the first aperture 420 and the second aperture 422 formed into the center housing 406 are larger than the diameters of the first opening 544a and the second opening 544b formed into the center post 534 for injecting gaseous fuel. Moreover, the first aperture 420 and the second aperture 422 are positioned such that they vertically overlap with the first opening 544a and the second opening 544b. That is, the first aperture 420 and the second aperture 422 are positioned such that they are vertically aligned with the first opening 544a and the second opening 544b.

The pilot light 538 and ignitor 536 may produce a pilot light flame and ignite gas streams from the first and second openings 544a, 544b. The pilot light 538 may have a tube 554 that extends toward an electrode 556 of the ignitor 536. Likewise, the electrode 556 may extend toward the tube 554. The tube 554 and electrode 556 may extend above one of the first or second opening 544a, 544b and toward the first or second path 442a, 442b, respectively. For the example in fire pit 500, the tube 554 and electrode 556 may extend above and toward the area of the second opening 544b and toward the second path 442b. For another example, the tube 554 and electrode 556 may extend above and toward the area of the first opening 544a and toward the first path 442a.

Gaseous fuel may pass through the pilot light 538 and be injected toward the electrode 556 by the tube 554. When the ignitor 536 sends a current through the electrode a spark may be generated to ignite gaseous fuel provided by the pilot light 538 to produce a pilot light flame. When fuel is passed through the first and second openings 544a, 544b, the pilot light flame produced by the pilot light 538 and ignitor 536 may ignite gas streams along the first and second paths 442a, 442b, and therein may produce two streams of flame. The streams of flame may extend the distance 443 along the first and second paths 442a, 442b. For example, streams of flame from first and second openings 544a, 544b may be of a high pressure and increase the distance 443 compared to streams of flame that may be generated from openings of larger sizes. For this example, the flames may have increased visibility by extending further above the burner 504.

The wall 416 and plate 418 of the center housing 406 may prevent external forces, such as a breeze, from disrupting the ignition of a pilot light flame by the pilot light 538 and ignitor 536 and the gaseous streams of fuel along the first and second paths 442a, 442b. While the second openings 460 may provide air to and a passage for emissions to leave the center housing 406. The second openings 460 may therein prevent the smothering a pilot light flame, a spark, and/or an ignition of fuel within the center housing 406 due to lack of oxygen or buildup of emissions.

Thus disclosed herein is a fire display device, with a center housing enclosing or partially enclosing a pilot light, ignitor, and a plurality of openings in a center post. The pilot light and ignitor may generate flames ignited from gas stream from the openings in the center holes. The flames may be directed out of the housing through a plurality of apertures in the top of the housing. The apertures in the top of the housing may inject flames to a focal point where multiple fuel streams are injected from corresponding fuel injection ports. The fuel at the fuel injection port may be ignited by the flames to produce a flame at a distance above the burner that may be more visible and less likely to be altered by the whipping effect.

The disclosure also provides support for a method for operating a fire display device, comprising: forming at least one stream of flames within a center housing, and directing the at least one stream of flames through one or more apertures formed into an upper surface of the center housing and vertically above the center housing. In a first example of the method, the method further comprises: directing one more gaseous fuel streams towards the at least one stream of flames vertically above the center housing. In a second example of the method, optionally including the first example, the at least one stream of flames is formed by injecting gaseous fuel through one or more injection ports formed into a center post that is positioned within the center housing, and igniting the gaseous fuel that is injected through the one or more injection ports via an ignition configuration that is also positioned within the center housing. In a third example of the method, optionally including one or both of the first and second examples, the method further comprises: injecting one or more gaseous fuel streams towards the at least one stream of flames and above the center housing via fuel injection ports positioned outside of the center housing. In a fourth example of the method, optionally including one or more or each of the first through third examples, directing the at least one stream of flames through the one or more apertures includes directing two streams of flames through two apertures in a twin tail formation. In a fifth example of the method, optionally including one or more or each of the first through fourth examples, the center housing is cylindrically-shaped, and wherein the upper surface of the center housing comprises a substantially planar surface.

The disclosure also provides support for a fire display device, comprising: a center post comprising an injection port formed therein, wherein the injection port is configured to flow a stream of gaseous fuel therethrough, an ignition configuration adjacent to the center post and configured to ignite the stream of gaseous fuel, and a center housing at least partially enclosing the center post and the ignition configuration, the center housing comprising an aperture formed therein configured to pass the ignited gaseous fuel therethrough. In a first example of the system, the aperture is formed into an upper surface of the center housing, and wherein the upper surface of the center housing is substantially planar. In a second example of the system, optionally including the first example, the injection port is a first injection port, wherein the stream of gaseous fuel flowed through the first injection port is a first stream of gaseous fuel, and wherein the center post comprises a second injection port formed therein that is configured to flow a second stream of gaseous fuel therethrough. In a third example of the system, optionally including one or both of the first and second examples, the first stream of gaseous fuel and the second stream of gaseous fuel are ignited within the center housing via the ignition configuration. In a fourth example of the system, optionally including one or more or each of the first through third examples, the ignition configuration includes an ignitor and a pilot light gaseous fuel source. In a fifth example of the system, optionally including one or more or each of the first through fourth examples, the aperture of the center housing is vertically aligned above the injection port of the center post, and wherein a diameter of the aperture is greater than a diameter of the injection port. In a sixth example of the system, optionally including one or more or each of the first through fifth examples, the system further comprises: injecting one or more gaseous fuel streams towards the ignited gaseous fuel above the center housing via additional fuel injection ports, wherein the additional fuel injection ports are positioned outside of the center housing. In a seventh example of the system, optionally including one or more or each of the first through sixth examples, the additional fuel injection ports are positioned circumferentially around the center housing.

The disclosure also provides support for a fire display device comprising: a center post configured to provide two flame streams in a twin tail formation that extend in a substantially vertical direction above the center post, a center housing at least partially enclosing the center post, the center housing comprising a first aperture configured to pass a first flame stream of the two flame streams therethrough and a second aperture configured to pass a second flame stream of the two flame streams therethrough, and a plurality of fuel injection ports positioned around the center post and the center housing. In a first example of the system, the each of the plurality of fuel injection ports is configured to inject a gaseous fuel stream towards the two flame streams above the center housing.
