The present description relates generally to methods and systems for controlling a fire display.
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. In some cases, it may be desirable to equip a space with multiple fire display devices including multiple fire pits and/or torches. However, pressure regulation may be challenging, and it is additionally inconvenient to procure separate fuel sources for each fire display device. Further, it may be desirable to coordinate the fire display devices to a common input, such as an audio input. Coordinating fire display devices may be result in an entertaining and/or theatrical effect. For example, it may be desired to coordinate fire bursts of the fire display devices to an audio input and with each other without a lag time.
In one example, the issues described above may be addressed by a fire display system comprising a fuel source, a common fuel line coupled to the fuel source via a first pressure regulator, and a first fire display device fluidically coupled to the common fuel line via a second pressure regulator. The first pressure regulator provides the gaseous fuel to the common fuel line at a first pressure, and the second pressure regulator arranged downstream of the first pressure regulator provides the gaseous fuel to the first fire display device at a second pressure that is lower than the first pressure. Further fire display devices may additionally be coupled to the common fuel line in a similar manner as the first fire display device.
In this way, pressure regulation is achieved for improved fire display device operation. Further, multiple fire display devices may share a single fuel source and a single audio input communicated without lag. Further, the number of fire display devices may be increased or decreased without the need for additional tools and minimizing a risk of release of fuel gas to the atmosphere. Additionally, the entertainment and theatrical effect of multiple fire display devices may be increased by coordinated response to an audio input and by positioning of a pilot light at a central focus point of fuel in a burner.
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.
The following description relates to systems and methods for a fire display system which may include multiple fire display devices. A fire display system including multiple fire display devices arranged in a display is shown in an example environment in
For purposes of discussion, the below figures are described collectively. Thus, similar elements may be labeled similarly and may not be re-introduced.
Turning first to
In addition to the torches 102, the system environment 100 includes additional fire devices including a first fire pit 104a, a second fire pit 104b, and a third fire pit 104c (also referred to collectively 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 system 101. Each fire pit 104 and torch 102 may include a respective fire device controller, wireless receiver, input panel, and a battery, similar to the examples discussed further below with respect to
The hub 110 is an electronic controller that includes a processor with instructions stored in non-transitory memory that, when executed, cause the hub 110 to send 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 wireless receivers of the respective torches 102 and fire pits 104. Each of the torches 102 and fire pits 104 additionally includes an ignitor and at least one valve positioned therein that is configured to adjust an amount of fuel provided for ignition of the respective torch or fire pit responsive to signals (e.g., electronic signals) transmitted to the respective fire device controller by the hub 110. For example, responsive to a given fire device controller receiving control signals from the hub 110, the fire device controller may command the torches 102 and fire pits 104 to actuate at least one of the electric valve and the ignitor of the respective torch 102 and fire pit 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 (e.g., to the respective electronic controllers of the one or more 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 (e.g., to the respective electronic controllers of the one or more 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 includes 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 made by a user of the fire display system and received at the hub 110. Additionally or alternatively, a mode selection may be received at the input panels of the respective torches 102 and fire pits 104. 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. In examples where hub 110 is an application executed at a mobile device, the audio input may be stored at and/or wireless streamed by the mobile device and accessed by the application. 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 for torches 102 and/or fire pits 104, 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, adjusting the torches 102 or fire pits 104 to operate in the flame boost mode may include adjusting a mechanical valve providing fuel to the burner to a wide open position (e.g., fully opened 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 user 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 user 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 require 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 or sub-group.

At 606, method 600 includes opening a bleed valve such as bleed valve 217 described above with respect to
At 608, the method includes determining whether air has been vented from the common fuel line. Determining if the air has been vented from the common fuel line may be done manually by an operator and may include identifying a smell of propane gas coming from the bleed valve, indicating that there is no air remaining in the common fuel line. Alternatively, a user may determine a threshold amount of time for the bleed valve to remain open, after which the air is considered to be vented from the common fuel line. In one or more examples, the bleed valve may be automatically opened and held opened for the threshold amount of time to purge air from the common fuel line.
If it is determined that air has not been vented from the common fuel line at 608, the method continues to 609 and the bleed valve is maintained in an open position until air is vented as determined by smell or elapsed time as describe above with respect to step 608. If it is determined that air has been vented from the common fuel line at 608 or at 609, the method continues from 608 to 610 where the method includes closing the bleed valve.

At 672, method 650 determines if the user input is to turn the fire display device off. If the user input is not to turn the fire display device off, then method 650 returns to 652. If the user input is to turn the fire display device off, method 650 continues to 674 and closes all fuel valves. All fuel valves may include both the mechanical valve and the electric valve. If both the mechanical valve and electrical valve are communicatively coupled to the controller, then all fuel valves may be closed at one or more fire display devices by a command from the control module. The command may be wirelessly issued to the control module by the control hub. If the mechanical valve is not communicatively coupled to the controller than closing all fuel valves may include physically closing the mechanical valve at the user input device as well as a command from the control hub.
