The following disclosure relates generally to fountains and, more particularly, to water fountains that include a gas-fired flame.
Water fountains and devices displaying fire have long been treasured individually for their decorative and entertaining qualities. Fountains ranging in size from a small desktop display with a trickle of water to a large sculpted work of art spraying hundreds of gallons of water have been admired and sought after for hundreds of years. Likewise, the captivating and artistic nature of fire in the form of the home fireplace, an outdoor fire pit, or even the group bonfire has long been a central part of modern décor long after the functional values of such devices where superseded by technology.
The contrast between fire and water could not be more apparent and their combination has often been used in artistic renderings. The effective introduction of fire to a water fountain is not, however, a simple task and has long remained a technical challenge. Previous attempts to display fire and water in the same device have been attained by limiting or preventing any interaction between the flames and water. Normally, any apparent interaction of the two elements is through creative designs capitalizing on an observer's lack of depth perception to seemingly show that the flames and streams of water are interacting when in reality they are completely separate. One example of such a device is a fireplace and water fountain combination described in U.S. Pat. No. 5,092,312. While such illusions can be very intricate, they remain illusions that cannot display the true effects of a fountain's water interacting with a ring of fire.
In the drawings, the same reference numbers identify identical or substantially similar elements.
A display device having a water fountain with streams of water interacting with fire in accordance with embodiments of the present invention are disclosed and shown in
The following discussion provides a general overview of the orientation and structure of the fire and water fountain and then presents a more detailed discussion of the gas distribution and water dispersion assemblies. Throughout this disclosure, alternate embodiments of the device are presented to display the robust nature of the device. In general, alternatives and alternative embodiments described herein are substantially similar to previously described embodiments, and common elements and functions are identified by the same reference numbers. Only significant differences in construction or operation are described in detail.
The streams of water 110 terminate on top of a bed of anti-splatter aggregates 112, which is supported by a retaining grate assembly 114. In this illustrated embodiment, the bed of anti-splatter aggregates 112 consist of numerous small transparent glass spheres 113 removably supported on a grate assembly 114 in the reservoir 102. The spheres 113 provide non-planar surfaces for termination of the streams of water 110 that reduce the splattering of water when the streams of water 110 land in the reservoir. The anti-splatter aggregates 112 can be made of other materials, such as stone or any suitable water-resistant material or may have different geometric shapes, sizes and optical characteristics. The grate assembly 114 supports the anti-splatter aggregates 112 at a fix distance relative to the bottom of the reservoir 102. The grate assembly 114 is perforated to allow water to drain through to the reservoir, yet the perforations are smaller then the aggregates to prevent them from falling in. The grate assembly 114 also has a plurality of generally annular cutouts positioned and sized to receive the gas distribution assemblies 104 and the water dispersion assemblies 106.
In the illustrated embodiment, the inner gas conduit 118 is configured to direct the flame 108 (
The fire and water display device 100 shown in
The top lip 132 of the upper basin 128 is at a level above the water dispersion assemblies 106 and the gas distribution assemblies 104 of the illustrated embodiment. The water level is controlled via a water level sensor 134 positioned in the upper basin 128 such that the water level does not exceed the upper surface of the gas distribution assembly 104 or the water dispersion assemblies 106. Also, a water temperature sensor 136 (
The central well 130, in this embodiment, is of sufficient size to house a submersible pump 138 and lighting fixtures 140. The pump 138 is fluidly coupled to the water dispersion assemblies 106 such that water from the central well 130 is pumped to and dispensed through either the central water nozzle 124 or the outer water ring 126. The dispensed water can be collected via the upper basin 128 and directed back to the central well 130 for reuse and conservation. In alternate embodiments, a nonsubmersible pump can be located remotely from the reservoir 102 and configured to selectively pump water from the central well 130 to the water dispersion assemblies 106. In configurations that include more than one water dispersion assembly 106, a selector valve can be coupled to the output of the pump 138 to selectively direct the water to one or a combination of the water dispersion assemblies 106. Accordingly, a user can control fountain operation and the water distribution from the water dispersion assemblies 106. The pump 138 can also be manually or automatically controlled to adjust the size of the trajectory of the water streams 110. Water flow from the pump 138 can also be turned off or activated at selected time intervals so the display device 100 can act as a source of flames alone, with the water in the upper basin acting as a reflecting pool. Similarly, the gas flow through the gas distribution assemblies 104 to control flame size relative to the streams of water, or to temporarily turn off the flames so the display device 100 acts as fountain without the flames. Activation of the gas flow can also be controlled for creation of the flames at selected times and in selected patterns to interact with the streams of water 110 (FIGS. 1 and 2).
In one embodiment, a lighting fixture 140 includes a plurality of submersible lamps 142 are provided in the central well 138, and a submersible annular light assembly 144 is provided in the upper basin 128. The lamps 142 and the annular light assembly 144 are aimed upwardly to enhance the esthetic effectiveness of the interaction between the fire and the water streams 110 (FIG. 2). The light from the lamps 142 and the annular light assembly 144 is refracted, reflected and disbursed through the anti-splatter aggregates 112 and the perforated retaining grate 114. The light can also be selectively modified by providing colored lenses on the light fixtures 140 or by providing colored bulbs in the fixtures.
Control devices 145, coupled to the pump 138, the lighting fixtures 140, and to gas control valves are provided in a control housing 147 adjacent to the reservoir 102. The control devices 145 in one embodiment can be controlled at the control housing, or they can be controlled from a control at a location remote from the control housing. The remote controls can be hard-wired to the control devices, or they can be wireless controls using conventional wireless controls.
In another embodiment, the control devices 145 are remotely located from the reservoir 102 and are coupled to the pump 138, lighting fixtures 140, and/or gas control valves by electrical and/or gas conduits. Accordingly, the fire and water display device 100 can be located in one location, such as a yard, foyer, lobby, atrium, etc., and the control devices 145 can be provided at an easily accessible, remote location. These remotely located control devices can also be operated by hard-wired controls or wireless controls.
The gas conduit 146 shown in
Located in proximity to the aperture 150 is an igniter assembly 152 positioned to ignite the flammable gas just after the gas has exited the aperture and is adjacent to the conduit's upper surface. One or more igniter assemblies 152 can be associated with each gas conduit 118, 120 to ensure proper and adequate ignition of the flammable gas upon release through all of the aperture 150. The igniter assembly 152 can be automated or can be manually operated.
In the illustrated embodiment, a water shield 154 is coupled to the gas conduit 146. The water shield 154 generally has an inverted “L”-shaped cross-section formed by a vertical leg 156 and a horizontal leg 158. The vertical leg 156 is positioned adjacent to the side of the gas conduit 146 so that the horizontal leg 158 is spaced above the gas conduit. The gas flowing from the gas conduit's apertures 150 is ignited by igniter assembly 152 while the gas is below the water shield's horizontal leg 158 and in the space above the gas conduit 146. The space between the water shield 150 and the apertures 150 allows the gas being released from the gas conduit 146 to mix with ambient air to provide a selected air-to-fuel mixture for ignition. By controlling the dimensions of this space, different gas-air mixtures can be achieved that, in turn, modify the characteristics of the resulting flames 108 (FIG. 2).
The horizontal leg 158 is positioned away from the apertures 150 to avoid interference with the flow of gas through the apertures. The space between the water shield's horizontal leg 158 and the aperture 150 can be controlled when securing the vertical leg 156 adjacent to the gas conduit 146.
