Abstract
A bowl that is configured for containing liquid such as water has a gas distribution apparatus in the bowl beneath the surface of the liquid and a gas source attached thereto. The gas distribution apparatus includes a movable gas distribution conduit that may be controlled to move in a predetermined pattern so that gas bubbles are emitted in a desired and controlled manner, or alternately, includes a gas distribution plate that causes gas bubbles to emit in a random manner. When the bubbles of gas burst at the surface of the liquid they are ignited, resulting in pleasant displays of flame.
Description
- This invention relates to an apparatus for generating a flame, and more particularly, the invention relates to an apparatus for generating a flame above a surface of a liquid from a combustible gas that is bubbled through the liquid to the surface where it is ignited.
- In addition to their utilitarian properties, many people find both flames and fire aesthetically pleasing—hence the ubiquitous use of fireplaces and candles and the like. Similarly, water features such as fountains, ponds, streams are also very soothing to many people. It is not surprising therefore that inventors have combined both fire and water in a variety of different ways in order to make aesthetically pleasing and entertaining displays and there are numerous technologies for facilitating the displays.
- There are numerous known systems for generating a flame above a body of liquid, typically water, for the ornamental and visual effects that can be created. Many of these are large systems found in resort settings such as Las Vegas, and are used primarily for entertainment. Although there are many different types of systems, they generally involve the ignition of combustible gas above the surface of the water, and often include a variety of colored lighting elements and fountains and the like. Such large-scale entertainment systems are enjoyable but tend to be complex and expensive, and therefore not applicable to most consumer settings.
- The present invention relates to apparatus that is designed primarily for the home consumer market and is defined by a bowl that is configured for containing liquid such as water, and a gas source combined with apparatus to cause the gas to bubble through the liquid. When the bubbles of gas burst at the surface of the liquid they are ignited, resulting in pleasant displays of flame. The invention comprises various embodiments that allow for variation in the pattern of gas bubble ignition, the timing of ignition, and may include lights and other features as detailed below.
- The invention will be better understood and its numerous objects and advantages will be apparent by reference to the following detailed description of the invention when taken in conjunction with the following drawings.
-
FIG. 1 is a perspective view of a first illustrated embodiment of the present invention. -
FIG. 2 is a top plan view of the embodiment illustrated inFIG. 1 . -
FIG. 3 is a perspective view of a portion of the embodiment illustrated inFIG. 1 , and more particularly, the gas distribution system. -
FIG. 4 is a top view of a component of an illustrated embodiment according to the present invention that includes a central gas bubble dispersion plate. -
FIG. 5 is a perspective view of the lower side of a gas bubble dispersion plate according to the embodiment shown inFIG. 4 . - In the following description, the use of “a,” “an,” or “the” can refer to the plural. All examples given are for clarification only, and are not intended to limit the scope of the invention.
- Referring now to
FIGS. 1 and 2 , afirst apparatus 2 for entertaining and producing a fire show comprises abowl 4 having alip 6, a support frame 8, adish 10, a plurality of rocks 12 (or other decoration), avertical gas exhaust 14,lights 16,gas hose 18,electrical apparati 20, anddish support 22. - The
bowl 4 is a container configured to hold a liquid, such as water illustrated with dashed lines inFIG. 1 , and may take any shape. For instance, inFIGS. 1 and 2 , thebowl 4, when viewed from above, has the shape of a square, but when viewed from the side (or a cross section) has a concave or partial circle shape. In the embodiment shown inFIG. 4 , abowl 104 has a circular shape when viewed from above, although any the bowl 4 (or 104) may take on any shape such that the bowl can contain a liquid. The bowl 4 (and other components of thesystem 2, includingdish 10, support frame 8, etc.) may further comprise any hard material, such as metal, glass, or ceramic, but may also include plastic, wood, or any other material. While theapparatus 2 burns a combustible fuel, the system is safe and there is no risk that thebowl 4, if composed of a combustible material, will burn. In practice it has been found that the preferred depth of the water held in the bowl should be no less than about 6 inches, and no greater than about 12 inches at the position where the gas bubbles burst at the surface of the liquid. It will be appreciated that these dimensions may be varied somewhat without adversely affecting the performance of the invention. - The
bowl 4 comprises alip 6 or raised extension that preferably rises between 1 and 3 inches above the surface of the water (or liquid) contained inbowl 4. This will help ensure that wind will not extinguish the fire show occurring above the water surface. Thelip 6 may ascend at the same angle as the edge ofbowl 4 or may be substantially vertical or horizontal (as shown inFIG. 1 ). - The support frame 8 is configured to support the
bowl 4, its liquid contents, and other elements of thesystem 2. The support frame 8 may be designed to break, collapse, or fall apart when exposed to a weight exceeding a certain limit or threshold, such as 20 or 30 pounds. This is a safety feature to prevent a small child from climbing on thesystem 2 and drowning in the water contained inbowl 4. Any known method for causing the breakage or collapse of support frame 8 is within the scope of the present invention, including building the support frame 8 of a sufficiently thin gauge metal to allow it to bend when subjected to a sufficient force or weight, including scissor-type hinges or other collapsing or folding apparati, etc. -
Dish 10 is connected to thebowl 4 viadish support 22.Dish 10 may have the shape of a plate, bowl, or surface with a peripheral lip or raised extension to holddecorative rocks 12 in place. Dish support 22 preferably supports thedish 10 above a lower surface of thebowl 4, such as between 0.5 and 2 inches, in order to allow for the placement and movement of rotating bubble disperser 30 (FIG. 3 ).Decorative rocks 12 may include rocks, pebbles, marbles, or any other decorative element. In the center of dish 10 (and decorative rocks 12) protrudesvertical gas exhaust 14 of rotating bubble disperser 30, from which flammable gas is emitted. Thevertical gas exhaust 14 may be configured to be above or below a surface of the liquid contained inbowl 4, but is preferably above. Theexhaust 14 may be designed to emit gas at a slow and steady stream to provide for a “pilot light” to keep the fire burning above the liquid surface and to re-ignite the gas should it extinguish. -
Lights 16 are shown inFIGS. 1 and 2 to be located along the diagonals of square-shaped bowl 4, although they may be located anywhere within or onbowl 4, preferably in such a manner that they are submerged when thebowl 4 is filled with the liquid.Lights 16 may be any known lights, such as incandescent or LED, and may be of any color, combination, intensity, and power consumption. Further, thesystem 2 may include acomputer processor 23 connected tolights 16 and configured to cause the lights to illuminate in a predetermined fashion, such as in a predetermined sequence, timing, color scheme, changing intensity/brightness, and so forth. Further, theprocessor 23 may be configured to cause the lights to pulsate or change in accordance with music that is playing either through the processor or remotely from the processor. In the latter case, the processor may include a microphone and may be designed to sense the music (e.g., a beat to the music) and then output a signal to thelights 16 in accordance with a preprogrammed association with the music (such as flashing the lights or changing the colors or sequencing the lights to the beat of the music). Thesystem 2 may include one or more, preferably at least four,lights 16. - The
gas hose 18 connects a source of combustible fuel such as a bottle ofpropane 19, natural gas, etc., to the rotating bubble disperser 30 via one or more valves including acheck valve 21 shown schematically inline inhose 18. For instance, in addition to the one-way check valve 21, another valve may be an on-off valve, another may be a safety release or pressure relief valve, and so forth.Check valve 21 is a conventional backflow preventer valve that allows gas to flow in one direction through the valve (i.e., from the bottle of propane to the bubble dispenser 30), but will not allow water or other liquid to flow in the reverse direction into thegas supply line 18. In another embodiment, another valve may be a variable solenoid valve that may be connected to or controlled by a computer processor such asprocessor 23, thus allowing the flow rate of combustible gas through rotating bubble disperser 30 to be adjusted in real time, such as in accordance with a program that depends on music. In other words, in place or in addition to the embodiment in which a computer processor is connected to thelights 16 to cause them to illuminate according to a program that depends on the sound or beat of music, the variable solenoid valve may be connected to the processor and configured to variably open or close according to a program that depends on the sound or beat of music. Such a valve (or lights 16) may alternatively or in addition be controlled by other factors and sensors, such as a light level, a time of day, a time of year, a temperature, and so forth. For instance, the variable solenoid valve may be programmed to open more when the temperature is low in order to provide greater heat of combustion, as well as to compensate for the fact that the combustible fuel pressure may be lower when the temperature is lower. Further, thelights 16 may be programmed to illuminate when the sun goes down, etc. -
Electrical apparati 20 may include a wall outlet plug, batteries, capacitors, wiring, transformers, electrical sparking devices, and so forth. Theapparati 20 may be configured topower lights 16, a processor 23 (if any), a valve, a combustion ignition system, and so forth. - Referring now to
FIG. 3 , thesystem 2 ofFIG. 1 is shown withoutdish 10 anddecorative rocks 12, exposing the rotatingbubble disperser 30 which comprises a vertical conduit 32 (having vertical gas exhaust 14), a horizontal conduit 34 (havinghorizontal gas exhaust 36 at the distal end thereof), a T-joint 38, afirst gear 40, and a second gear 42. - The
conduits joint 38 to a source such as a bottle ofpropane 19, which is not shown inFIG. 3 but is as detailed above with respect toFIG. 1 , or other combustible gas viagas hose 18, again as detailed above, so that gas traveling through gas hose 18 (and the installed valves) also travels throughconduits bubble disperser 30 is preferably rotatably connected or affixed to thebowl 4 and/ordish 10, such that thevertical conduit 32 passes through thedish 10 and/orrocks 12, andhorizontal conduit 34 can be rotated (about an axis parallel to vertical conduit 32) underneath thedish 10. The second gear 42 is connected to a motor (not shown) or other mechanical powering device, and engaged with first gear 40 (which may be larger or smaller than second gear 42) so that the motor causes the rotating bubble disperser 30 to rotate via interaction betweengears 40, 42. The motor may also be connected to and/or controlled by a computer processor such asprocessor 23, so that it can be turned on or off, and its speed altered or varied, by the preprogrammed processor and/or in response to sensors. As an example similar to that given previously, a microphone could detect the beat of music and the processor could cause the motor to spin synchronously or in response to the music. - The
system 2 may include an electric ignition system, shown schematically atreference number 21 inFIG. 2 , such as a spark generator (which may include a spark plug, transformers, and so forth), a piezoelectric device, or any other means for igniting a flammable gas. For instance, an igniter may be located at or near thevertical gas exhaust 14 to allow ignition of the pilot light, and/or there may be one or more igniters around the periphery of thebowl 4 corresponding to where gas (that is emitted at horizontal gas exhaust 36) bubbles up and surfaces from the liquid surface, to allow this gas to be ignited. The electrical igniter may be hand- or human-operated, allowing a user to ignite the gas after the valve has been opened and gas is flowing through the rotatingbubble disperser 30. Alternatively or in addition, acomputer processor 23 may be connected to and programmed to cause the igniter to ignite according to certain conditions, such as if the fire extinguishes (a heat or light sensor may be connected to the processor to detect this issue), or at a certain time of day or according to certain weather conditions. - In operation, the
apparatus 2 may be turned on by opening an “on” valve (which may or may not be performed at least in part by a computer processor) of the flammable gas, allowing gas to flow through the rotatingbubble disperser 30. Further, the motor may be turned on (again, which may or may not be performed at least in part by a computer processor), causing the rotatingbubble disperser 30 to rotate. The igniter may be turned on so that gas that is released, such as from vertical gas exhaust 14 (which may or may not provide for a pilot light), can be ignited. As gas is emitted through the distal tip ofhorizontal gas exhaust 36, it bubbles upward through the liquid (water) and, when it reaches the surface, it is ignited with air by either or both of the pilot light (burning at the center of thedish 10 via vertical gas exhaust 14) or heat from the burning of previous flammable gas bubbles. As therotating bubble disperser 30 continues to rotate, the bubbles bubble upward toward the surface of the liquid in what appears to be a circle or spiral, producing the appearance of burning gas “chasing” itself around thebowl 4 and rocks 12. Thelights 16 may be illuminated at the same time, and any aspect of the lights, the rotating speed, the gas emission (and thus combustion) rate, and so forth may be adjusted manually and/or by thecomputer processor 23. - A length of the
horizontal conduit 34 may be greater, less than, or approximately the same as a radius ofdish 10. If less, then bubbles emitted fromhorizontal gas exhaust 36 may contact and travel up the outer side ofdish 10. Alternatively or in addition, thehorizontal conduit 34 may be designed (such as at least partially out of a flexible rubber or plastic) such that thehorizontal gas exhaust 36 conforms to a predetermined shape or path. For instance, thedish 10 may be specially shaped, like as a star or heart or any other shape, and thehorizontal gas exhaust 36 may travel along the periphery (e.g., via a track, via a spring-type force of a rubber tube pressing against the periphery, etc.), causing the “chasing fire” to be created in the shape of the predetermined shape. Further, thehorizontal conduit 34 need not actually be horizontal; this is merely a designation for explanation of the invention. Ultimately, the rotatingbubble disperser 30 may be designed, shaped, or configured in any way to cause the path of gas bubbles to the liquid surface to take on any preferred path, design, shape, or display. - Referring now to
FIG. 4 , a second illustrated embodiment ofapparatus 102 for entertaining and producing a fire show comprises a bowl 104 (which may as described with reference to bowl 4) having a lip 106 (which may be as described with reference to lip 6), and abubble dispersion plate 108 located preferably in the center of thebowl 104. Thebowl 104 is filled with a liquid, and thesecond system 102 preferably includes a dish and decorations (likedish 10 androcks 12 inFIG. 1 ), which are not shown. Underneath theplate 108, flammable gas is bubbled, plumbed, or directed upward, and the plate 108 (which will be discussed more with reference toFIG. 5 ) is configured to disperse these bubbles in different paths, so that they bubble upward through the liquid and burn above the liquid in a somewhat random (or “dancing”) formation or display, as shown with the arrows emanating from dispersion plate inFIG. 4 . Other features of the second system 102 (such as the support, ignition system, computer processor, lights, etc.) may be similar to that disclosed with reference tofirst system 2. - Referring now to
FIG. 5 , thebubble dispersion plate 108 includesgas collection chamber 110,plural gas paths 112,path walls 114, andperipheral seals 116. Theplate 108 is preferably, but need not be, circular in shape. Thegas collection chamber 110 is a chamber in which flammable gas can collect (from a source below) and then allow the passage of gas to and throughpaths 112. InFIG. 5 , thegas collection chamber 110 is shown as a recess or concavity into which gas bubbles can collect and congregate. - The
gas paths 112 allow gas to travel from thegas collection chamber 110 to the liquid surface via bubbling up through the liquid. There are preferably at least five paths 112 (and preferably at least six, and more preferably at least eight) because with fewer than fivepaths 112, it may be difficult to sustain combustion with an ongoing flame at the liquid surface. Thepaths 112 may but need not be spaced apart evenly. - Further, the bubbles should be sufficiently large, which implies and requires that the
path 112 dimensions should be sufficiently large. In one aspect, they are preferably at least about ½ inch in cross sectional width, and more preferably at least 1 inch in cross sectional width.Path walls 114 define the sides ofgas paths 112 and contact (and preferably seal) with the surface of thebowl 104.Peripheral seals 116 are located betweenadjacent paths 112 and seal with the surface ofbowl 104, so that the only escape for flammable gas that has accumulated in thegas collection chamber 110 is viagas paths 112 and bubbling upward to the liquid surface. - In operation, the apparatus illustrated in
FIG. 4 may be turned on by opening an “on” valve (which may or may not be performed at least in part by a computer processor) of the flammable gas, allowing gas to flow intobowl 104 underneath theplate 108 and into thegas collection chamber 110. An electrical igniter may be turned on or activated so that gas that is released from one or more ofpaths 112 can be ignited. As gas is emitted fromchamber 110 and throughpaths 112, it bubbles upward through the liquid (water) and, when it reaches the surface, it is ignited with air by either or both of a pilot light (which may be burning at the center of a dish or decorative display contained thereon) or heat from the burning of previous flammable gas bubbles. As bubbles randomly emit fromdifferent paths 112, the bubbles rise upwardly toward the surface of the liquid in what appears to be a random and unpredictable dance, producing the appearance of burning gas “dancing” around thebowl 104. The lights (if any) may be illuminated at the same time, and any aspect of the lights, the gas emission (and thus combustion) rate, and so forth may be adjusted manually and/or by a computer processor. - In both embodiments, in order to ensure that previously combusting gas bubbles ignite subsequent bubbles, the size of the
systems horizontal conduit 34 should be sufficiently short, such as less than 8 inches and more preferably less than or about 5 inches, and the diameter ofplate 108 should be sufficiently small, such as less than 16 inches and more preferably less than or about 10 inches. - Further, any controlling of the
systems computer processor 23 via a remote control. For instance, a radiotransmitter may be used to instruct thesystem 2 to increase the speed of rotating of therotating gas disperser 30, the color or illumination oflights 16, and so forth. - In other embodiments, a moving or dancing flame or illumination can be created by combining a moving flammable gas discharge with a container of liquid. For instance, a “river” of water may flow around a bar, table, or other location. Within the river may be located a movable conduit through which flammable gas is emitted and bubbles up through the river and is ignited and burns on the water surface, producing a chasing or dancing flame. The speed, direction, etc., of the moving conduit may be altered or varied manually or using a processor.
- While the present invention has been described in terms of a preferred embodiment, it will be appreciated by one of ordinary skill that the spirit and scope of the invention is not limited to those embodiments, but extend to the various modifications and equivalents as defined in the appended claims.
