Abstract

An acoustically variable burner system is provided, having a burner wherein the flow of gas thereto, and consequently the flame pattern resulting from the ignition of the gas, is variable by transmission of acoustic waves therethrough via an acoustically-based control system. The preferred burner design produces a realistic, wood-burning type flame pattern. An acoustic controller, such as an APPLE® iPod®, MP3 player, computer, etc., may be utilized to drive/control electroacoustic transducers positioned adjacent the burner, the sound waves of which are produced thereby varying the flow rate of gas to the burner gas ports, thereby varying the flame height in direct correspondence with the audio signal. Further, the flame color may be altered by introduction of flame color variant compositions exposed to the flame via a flame color variation device removably positioned adjacent the burner. The system is preferably controlled via a specialized computer program running on the acoustic controller, which enables choice of flame patterns, duration, audible audio to accompany the flame display, etc.

Description

FIELD OF THE INVENTION

An acoustically variable burner system is provided, having a burner wherein the flow of gas thereto is variable by production of acoustic waves therethrough via an acoustically-based control system. Specifically, an acoustic controller, such as an APPLE® iPod®, may be utilized to drive transducers, the sound waves of which vary the flow rate of gas to the burner, thereby varying the flame height, etc.

DESCRIPTION OF THE RELATED ART

Historically, variation and control of gas flow to burners has been undertaken to control the amount of heat produced by the burner, as well as attempt to create a realistic (i.e., wood-burning) flame pattern. Conventionally, to achieve same, gas burners have comprised valve mechanisms for the control of gas flow thereto. Such valve mechanisms have varied in design tremendously, ranging from basic manual control to electromechanical control systems.
In addition to mechanical and electromechanical valve systems for control of gas flow, systems have been developed for control of the gas flow/flame produced by the burner using acoustic means. Specifically, U.S. Pat. No. 6,162,045 (hereinafter '045), the contents of which are incorporated herein by reference, discloses a gas burner system for producing dynamic flame patterns. As shown in FIGS. 3A and 4A, this is achieved by creating a standing wave within the burner via a transducer. However, although the '045 reference provides an alternate (i.e., acoustic) means of flame control, neither the gas burner system of the '045 reference, nor the prior art gas burners utilizing mechanical and electromechanical valve systems, provide a system capable of dynamically interactive flame control for entertainment purposes. Further, the burner shape fails to produce a realistic flame pattern due to its linear shape.
Accordingly, it is an object of the present invention to provide an acoustically variable burner system capable of dynamic acoustic control.
It is a further object of the present invention to provide an acoustically variable burner system capable of producing acoustically variable flames in a realistic wood-burning flame pattern.

DETAILED DESCRIPTION OF THE INVENTION

As illustrated in FIG. 1A-5, in a preferred embodiment, the present invention provides an acoustically variable burner system 1 comprised generally of a burner 3, one or more electroacoustic transducers 19 in communication with the burner 3, and a controller interface 21. As shown in FIGS. 1B and 2, the burner 3, which is configured to produce a wood burning-like flame, is comprised of a central gas chamber 5 in communication with a plurality of burner tubes 7. The burner tubes 7 are in communication with the central gas chamber 5 at a first end 9 of the burner tube 7, and a second end 11 of the burner tube 7 is disposed opposite the first end 9. The burner tubes may be linear or non-linear in shape. In a preferred embodiment, the burner 3 comprises a plurality of burner tubes 7, each burner tube having an arc-shape configuration.
The electroacoustic transducers 19 may be disposed adjacent the second ends 11 of the burner tubes 7, as illustrated in FIGS. 1A-3. Alternatively, in a preferred embodiment as illustrated in FIG. 4, an electroacoustic transducer 19 may be disposed adjacent the central gas chamber 5. In an alternative embodiment, the electroacoustic transducer may be replaced with and/or used in addition to other means/devices capable of emitting an acoustic wave into the burner tube(s), such as an electronically controlled valve, etc. Moreover, the disposition of the electroacoustic transducers 19 relative to the burner 3 may be varied in any desired manner, as long as sufficient acoustic wave energy is transmittable into the gas flow within the interior area 15 of the burner tubes 7 in such a manner as to create waves within the gas flow sufficient to alter the rate of flow thereof.
As illustrated in FIG. 7, the gas ports 17 are disposed through the burner tubes 7 so as to allow sufficient gas flow from the burner to create a desired flame pattern. In particular, in the preferred embodiment of the present invention illustrated in FIG. 7, the gas ports 17 are spaced apart in a descending manner, wherein the gas ports 17 are disposed closer together adjacent the central gas chamber 5, the distance between each gas port 17 increasing from the first end 9 of the burner tube 7 to the second end 11 of the burner tube 7. The present inventor has unexpectedly discovered that this configuration of gas ports 17, in conjunction with the plurality of semi-circle (arc-shaped) burner tubes 7, provides a very realistic flame pattern reminiscent of wood burning fires, as illustrated by the flame pattern shown in FIG. 3.
As shown in FIG. 6, electroacoustic transducers 19 are in communication with the controller interface 21. This controller interface 21 enables connection of various acoustic controllers with the system of the present invention. For example, in the preferred embodiment illustrated in FIG. 6, an APPLE® iPod® is provided as the acoustic controller. In further preferred embodiments, the acoustic controller may be one or more one or more of a computer (as illustrated in FIG. 10), stereo, portable electronic device (e.g., MP3 player), signal generator, and digital audio player. However, the acoustic controller should not be limited, but rather any device capable of transmitting an acoustic/audio signal to the system of the present invention may be used in conduction with the system herein.
As shown in FIGS. 6 and 9, in a further preferred embodiment, a radio frequency (RF) filter 35 may be installed between the controller interface 21 and electroacoustic transducers 19, so as to be in communication therewith. The RF filter 35 is operable to filter the audio frequencies transmitted by the acoustic controller 37, as desired by the system user. For example, as illustrated in FIG. 6, a sole or single set of RF filters may be utilized to filter all but one range of audio frequencies, thus producing a flame pattern correlating to a single frequency range. Alternatively, as illustrated in FIG. 9, two or more RF filters or sets of RF filters 35 may be utilized with multiple burner tubes 7, thereby enabling the creation of multiple flame patterns. The number of burner tubes, as well as RF filters, is unlimited.
In a further embodiment of the present invention, as illustrated in FIGS. 6, 9 and 11, a flame color variation device 27 may be disposed adjacent one or more burner tubes 7 via, for example, one or more retainer module supports 39. As illustrated in FIG. 11, each flame color variation device 27 is comprised of a retainer module 29 having a plurality of perforations 13 formed therein, the retainer module 29 operable to hold one or more flame color variant compositions 33. Upon exposure to a flame, the flame color variant compositions begin to burn, thereby causing the color of the flame to change color, the color dependent upon the specific flame color variant composition 33.
In particular, the flame color variant composition 33 may be any chemical composition capable of altering the color of a flame when exposed thereto. In a preferred embodiment, the flame color variant composition 33 is one or more of a strontium salt (creates a red flame), calcium chloride (creates an orange flame), sodium nitrate (creates a yellow flame), barium salts (creates a green flame), copper sulfate (creates a turquoise flame), copper chloride (creates a blue flame), potassium permanganate (creates a purple flame) and magnesium sulfate (creates a white flame). Alternative compositions capable of varying the color of flames may be disposed in place of, or in combination with, the above-identified compositions.
Preferably, the flame color variation device 27 is removable and replaceable, such that when the flame color variant composition therein is expended, the retainer module 29 may be refilled with fresh composition 33. Alternatively, the retainer module 34 may be prefilled and disposable, such that new modules 34 may be placed adjacent the burner 3 at will. In a preferred embodiment, as illustrated in FIG. 6, the flame color variation device 27 has a handle 34 or other means of handling, so as to enable a user to remove and replace retainer modules when needed or desired.
Additionally, the flame color variation device 27 may be utilized with any burner system, so as to color the flame thereof. In particular, the retainer module supports 30 and handle 34 may be tailored to interact with/mount on any conventional burner device. As long as the retainer module 34 is disposed adjacent a flame, the flame color variation device 27 is operable to color the flame, thereby providing decorative enhancement of the flame.
In a further preferred embodiment, the system further comprises a computer program product embodied on a computer readable medium for execution on/by the acoustic controller, wherein the computer program product is comprised of data operable to enable creation of a distinctive acoustic/audio signal which, when transmitted by the electroacoustic transducers 19, creates a predefined flame pattern.
For example, the computer program product (software application) is operable to: display list of flame pattern, and one or more of execution time (duration), frequency, and audio accompaniment options; enable input of desired flame pattern, and one or more of execution time, frequency, and audio accompaniment query a database of gas flow rate, acoustic frequency and amplitude corresponding to desired flame pattern; compile a user command comprising gas flow rate, acoustic frequency and amplitude, and one or more of execution time, frequency and audio accompaniment; and execute user command.
The computer readable medium 41 may be, for example, a hard drive external to and in communication with the acoustic controller 37. Alternatively, the computer readable medium 41 may be integrated into the acoustic controller 37, as illustrated in FIG. 6.
Although specific embodiments of the present invention have been disclosed herein, those having ordinary skill in the art will understand that changes can be made to the specific embodiments without departing from the spirit and scope of the invention. Thus, the scope of the invention is not to be restricted to the specific embodiments. Furthermore, it is intended that the appended claims cover any and all such applications, modifications, and embodiments within the scope of the present invention
