1. Field of the Invention
The invention relates to a fireplace fountain apparatus, in particular an apparatus which enables water to stream down the top and side portions of a fireplace surrounding a firebox.
2. Introduction
The ornamental display of fire and water is aesthetically pleasing to many observers. Several indoor and outdoor devices attempt to integrate these two opposed elements in a complimentary way. In indoor displays, the integration of the two is frequently made in order to suggest a natural, outdoor setting. Thus, the fire in the firebox is preferably presented suggesting a campfire and the water is preferably presented suggesting a tranquil waterfall or babbling brook.
Notwithstanding an aesthetic preference for the integration of the two elements in the indoor setting, during colder months, an indoor fireplace often also performs a heating function. A presentation which limits or diminishes the performance of this heating function should be avoided. However, in summer months, when maintaining a flame in the fireplace may be undesired it is preferable to still be able to present the water fountain display without accentuating the absence of a flame in the firebox.
U.S. Pat. No. 5,092,312 (“the '312 patent”) discloses a device which integrates water and fire in a fireplace display by spraying water upward from a moat adjacent to the firebox. The upward spray of the water both obscures the view of the fire and reduces the efficacy of the fireplace in heating. Such a display is also unnatural in appearance because upward spraying water rarely occurs naturally.
Similarly, U.S. Pat. No. 6,901,925 (“the '925 patent”) discloses an apparatus which allows water to fall from a hood extending above and forward of the firebox. Such a display is more natural in appearance than the display effected by the apparatus of the '312 patent, but still suffers the disadvantages created by cascading water in front of the flame, especially that the view of the flame is obscured and the heating function is impaired. It also precludes access to the firebox while the fountain is operational, which may be necessary for a variety of reasons, including, for example, in order to open or close the flue, to operate a pilot light, to stoke the fire or to add fuel. Thus, while the apparatus of the '925 patent may be somewhat useful in gas-fueled fireplaces, it is less advantageous for wood burning fireplaces. Finally, while the cascading water creates the impression of a waterfall, it does not convey the quieter serenity of flowing water.
Finally, neither the '312 patent nor the '925 patent discloses an apparatus which may easily be modified during seasons when maintaining a flame in the firebox is undesirable.
3. Objects of the Invention
It is, therefore, an object of the invention to provide a fireplace fountain apparatus which integrates water and fire in a way that presents the serenity of naturally flowing water without obscuring the presentation of the fire to the observer. It is also an object of the invention to provide a fireplace fountain which integrates the two elements in a fashion that neither diminishes nor hinders the production or transference of heat from the firebox to the surrounding room and does not prevent access to the firebox while the fountain is in operation. It is also an object of the invention to provide an apparatus which permits an easy modification of the device to display running water when fire is not displayed in the firebox and which modification affords energy efficiency in facilities that may be air conditioned during periods when the firebox is not in use. These and other objects are accomplished by the fireplace fountain apparatus disclosed herein.
According to the present invention, these objects are achieved by a fireplace fountain in which water flows over the surface of the top and side surfaces adjacent to the firebox. A diverting trough adjacent to the top of the firebox collects water flowing downward from above the firebox and directs it laterally to pipes communicating with a central reservoir basin at the base of the fireplace. Preferably the reservoir basin extends the full width of the fireplace. In such a configuration, the water flowing over the surface of the fireplace structure lateral to the firebox flows downward over the structure and directly into the reservoir basin.
A pump communicates water from the reservoir basin through pipes on the sides of the structure to the distribution pipe on the top of the fireplace. Water is directed to the top and side portions of the fireplace either by nozzles or, alternatively, through slots or holes in the distribution pipe adjacent the side and top portions of the fireplace. The water is delivered to the fireplace structure's surface in a volume and rate of flow which permits the water to flow over the structure, adhering thereto by surface tension, downward to the diverting trough or directly to the reservoir basin.
In an alternative embodiment, a non-porous insert is placed in front of the firebox. The insert may be installed by removing the diverting trough adjacent to the top of the firebox and the pipes lateral to the firebox and installing an insert of glass, Plexiglas or other non-porous material over the face of the firebox. The insert is then sealed to the outer face of the firebox. Alternatively, the insert may be installed by removing the bottom section of the diverting trough and sealing the top of the insert to the side wall of the diverting trough adjacent the fireplace structure. The sides of the insert are then sealed to the pipes lateral to the firebox. In this fashion the lateral pipes provide a supporting structure for the insert.
In either event, water flowing from the distribution trough at the top of the fireplace, flows over that portion of the fireplace structure above the firebox and then over the insert and directly to the reservoir basin. As water also continues to flow over the lateral portions of the fireplace structure, the effect created is a unitary wall of uninterrupted flowing water from the top of the fireplace structure to the bottom. In this fashion, the insert can be employed during warm seasons when use of the fireplace for heating or otherwise is unlikely. In such periods, the insert serves the additional salutary purpose of creating a barrier for air communicating from the room to the fireplace chimney, thus improving energy efficiency during months when the room is being air conditioned. The insert may be restored and the diverting trough assembly can be re-assembled during colder seasons to permit use of the fountain with the fireplace.
The invention is described in detail with reference to the following drawings in which like reference numerals refer to like elements:
As shown in
On the superior edge of the top portion of the fireplace structure, a generally horizontal distribution pipe (7) is disposed extending to the lateral extent of each lateral portion of the fireplace structure. The distribution pipe (7) comprises a means for delivering water from the pipe to the surface of the fireplace structure below the distribution pipe. A plurality of holes or slots in a portion of the distribution pipe adjacent to the fireplace structure is sufficient for this purpose. Alternatively, nozzles may be disposed to spray water under low pressure from the pipe to the surface.
On at least one end of the distribution pipe and preferably on both ends, generally vertical lateral pipes (8a, 8b) are disposed on the outside edges of the lateral portions of the fireplace structure. The lateral pipes extend downward in to the reservoir basin (6) and are in fluid communication with the distribution pipe (7).
At least one, and preferably two circulation pumps (9a, 9b) are situated within the basin and disposed to draw water from the basin and to deliver it through one or more lateral pipes to the distribution pipe. It is preferable to adjust the volume of water pumped so that water is delivered through the distribution pipe and to the fireplace structure under low pressure and so that the effect of water flowing over the non-porous surface of the fireplace structure is achieved.
In the preferred embodiment shown in
Disposed above the firebox aperture (5) is a diversion trough (10). The diversion trough extends to the full lateral extent of the aperture and is open on the top and disposed to received water flowing downward from the distribution pipe. The top edge of the trough adjacent to the fireplace structure is sealed flush to the structure. The diversion trough collects the water flowing downward from the distribution pipe toward the aperture and diverts it to one, or preferably both sides of the aperture.
In the preferred embodiment and as shown in
Where the fireplace structure is composed of porous material or for aesthetic reasons, a non-porous surface panel may be installed adjacent the fireplace structure in the area over which the water flows. Such a surface panel is sealed to the bottom edge of the distribution pipe (7), the inside edges of the lateral distribution pipes (8a, 8b) the top edge of the basin (6), as well as the lateral edges of the lateral diversion pipes (11a, 11b), and the top edge of the diversion trough (10). The surface panel may be made of a non-porous material and may be either flexible or rigid. For example, plastic film, Plexiglas, glass, mirrored glass, slate or other material may be used as a non-porous surface panel. Those skilled in the art will recognize that where a surface panel as disclosed herein is used, the apparatus may be freestanding and need not be affixed to the fireplace structure.
As shown in
A reservoir basin (6) at the base of the fireplace structure extends across the front of the aperture to the lateral extent of each lateral portion (3a, 3b) of the fireplace structure. The reservoir basin is of sufficient width and depth to permit the basin to retain water necessary for the operation of the fireplace fountain. At the locations where the top back edge of the reservoir basin meets the lateral portion of the fireplace structure, the edge is sealed flush to the structure. A bead of silicon sealer or other sealing mechanism may be used for this purpose.
The bottom edge of the insert (12) extends into the reservoir basin (6). Alternatively, the bottom edge of the insert is sealed flush with the top back edge of the reservoir basin (6) with a watertight, but removable seal. Waterproof tape, rubber, silicon or similar material may be used to form the seal.
On the superior edge of the top portion of the fireplace structure, a generally horizontal distribution pipe (7) is disposed extending to the lateral extent of each lateral portion of the fireplace structure. The distribution pipe (7) comprises a means for delivering water from the pipe to the surface of the fireplace structure below the distribution pipe. A plurality of holes or slots in a portion of the distribution pipe adjacent to the fireplace structure is sufficient for this purpose. Alternatively, nozzles may be disposed to spray water under low pressure from the pipe to the surface.
On at least one end of the distribution pipe (7) and preferably on both ends, generally vertical lateral pipes (8a, 8b) are disposed on the outside edges of the lateral portions of the fireplace structure. The lateral pipes extend downward into the reservoir basin (6) and are in fluid communication with the distribution pipe (7).
At least one and preferably two circulation pumps (9a, 9b) are situated within the basin and are disposed to draw water from the basin and deliver it through one or more lateral pipes to the distribution pipe. It is preferable to adjust the volume of water pumped so that water is delivered through the distribution pipe and to the fireplace structure under low pressure and so that the effect of water flowing over the non-porous surface of the fireplace structure is achieved.
In the preferred embodiment shown in
The alternate embodiment of the fireplace fountain invention shown in
When it becomes desirable to use the firebox for a fire, the insert may be removed and a diversion trough and diversion pipes may be re-installed. Similarly, when use of the firebox is not contemplated, the diversion trough and any diversion pipes may be removed and the insert installed.
The invention has been described in regard to its preferred embodiment. It will be apparent to those skilled in the art that the same may be varied in many ways without departing from the spirit and scope of the invention. All such modifications are intended to be included within the scope of the following claims.
