Benefit of U.S. Provisional Patent Application Ser. No. 60/756,317, filed Jan. 5, 2006, is hereby claimed and the disclosure incorporated herein by reference.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a storage tank, and more particularly a bladder tank for storing a liquid therein, which is suitable for mounting within a cabinet for a sink.
2. Description of Related Art
It is known to provide a water storage tank under a sink and within a cabinet for the sink. One such system is described in U.S. Pat. No. 5,704,078. However, such tanks are typically bulky and take up space within the cabinet that could otherwise be used for the storage of articles.
BRIEF SUMMARY OF THE INVENTIONIn accordance with one aspect of the present invention, provided is a bladder tank for storing a liquid. The bladder tank includes an outer housing and an inner bladder. A storage platform is mounted to the outer housing for storing an article thereon.
In accordance with another aspect of the present invention, provided is a cabinet. A sink is mounted to the cabinet. A tank for holding a liquid is located within the cabinet. A storage platform is mounted to the tank.
In accordance with another aspect of the present invention, provided is a faucet configured for mounting to a sink and a potable water storage tank forming an interior space. The faucet is in fluid communication with the interior space. A storage platform is mounted to the potable water storage tank.
In accordance with another aspect of the present invention, provided is a modified hydropneumatic tank from which an air valve has been removed. The tank includes a housing and a bladder located within the housing. The bladder divides an interior region within the housing into a first interior space for storing a liquid and a second interior space. A faucet having an operating lever is adapted for mounting within a faucet hole of a sink and is in fluid communication with the first interior space. A first normally closed valve controls a discharge of water from the first interior space through the faucet. A second normally closed valve controls a flow of water into the second interior space. Operation of the operating lever causes the first normally closed valve and the second normally closed valve to open.
In accordance with another aspect of the present invention, provided is a cabinet and a sink mounted to the cabinet. A bladder tank stores potable water. The bladder tank includes a housing and a bladder located within the housing for storing the potable water. The bladder tank is mounted beneath the sink and within the cabinet and is attached to an interior wall of the cabinet. A first article storage tray and a second article storage tray are mounted to the housing. A faucet assembly is mounted to the sink. A discharge orifice of the faucet assembly is in fluid communication with an interior space of the bladder for discharging potable water from the bladder. The faucet assembly includes a lever. The faucet assembly further includes a first normally closed valve for controlling the discharge of potable water from the bladder through the orifice. The faucet assembly also includes a second normally closed valve for controlling a flow of pressurizing water into a space between an interior surface of the housing and an exterior surface of the bladder. Operation of the operating lever causes the first normally closed valve and the second normally closed valve to open simultaneously.
In accordance with another aspect of the present invention, provided is a method of modifying a storage tank. The method includes the step of providing a hydropneumatic bladder tank for storing potable water. The tank forms a potable water storage chamber and an air storage chamber. The tank includes an air valve. The method further includes the steps of removing the air valve, and installing a conduit between the air storage chamber and a water source. The conduit includes a normally closed valve for controlling a flow of water from the water source to the air storage chamber.
BRIEF DESCRIPTION OF THE DRAWINGS
The bladder tank 10 further includes a first port 24 and a second port 25. The ports 24, 25 serve as connection points for conduits (e.g. pipe or tubing and valves, adapters, fittings, etc. associated therewith) to be connected to the bladder tank 10. As best seen in
Through the first port 24, a liquid is provided to the bladder 26 and stored therein. For example, purified water, such as permeate from a reverse osmosis water treatment system, may be stored in the bladder 26. Stored liquid is forced out of the bladder 26 by pressurizing the exterior of the bladder 26. To pressurize the exterior of the bladder 26, the space between the outer surface of the bladder 26 and the interior surface of the housing 20 is flooded with pressurizing water through the second port 25. The building in or at which the bladder tank 10 is installed will have a water distribution system that operates under pressure, for example 60 pounds per square inch (psi). Water from the pressurized distribution system is selectively provided to the space between the outer surface of the bladder 26 and the interior surface of the housing 20, flooding the area between the bladder and housing. Flooding the housing as described squeezes the bladder 26 and forces stored liquid out of the bladder 26. When the pressurizing water is shut-off, the remaining water in the space located between the outer surface of the bladder 26 and the interior surface of the housing 20 drains through the second port 25 and through a flow-restricted drain line (see
The bladder 26 is shown in
A schematic diagram of a process for providing water purification, permeate storage and permeate discharge is shown in
A first normally closed valve 48 is mounted along the permeate delivery line 43 and controls the discharge of permeate from the first faucet 13. A second normally closed valve 49 is mounted along the source water line 45 and controls the flow of pressurizing water into the space between the bladder and housing. In an embodiment, operations of the first and second normally closed valves 48, 49 are interlocked, so that the valves open and close together. This is shown schematically via the dashed line in
In an embodiment, the first faucet forms 13 is a faucet assembly for mounting to a standard faucet hole in a sink, such as a 1½ inch faucet hole. The faucet assembly includes the first normally closed valve 48 and the second normally closed valve 49. The faucet assembly further includes a manual operator (see
When permeate is not being demanded by a consumer, that is, when no consumer is actuating the lever 54 (see
It is to be appreciated that the first and second normally closed valves 48, 49 could be electrically operated valves that respond to, for example, a contact closure or an electrical signal, such as a voltage signal. Furthermore, the contact closure or signal could come from a remote device, such as an icemaker, and the valves 48, 49 could be used to provide permeate to the remote device or another device requiring permeate.
Conventional bladder tanks for holding permeate from a reverse osmosis water treatment system often use compressed air as the pressurizing fluid for squeezing the bladder to discharge permeate, rather than source water under distribution pressure as described above. Such tanks are known as hydropneumatic bladder tanks. The bladder divides the tank into a water storage chamber and a compressed air storage chamber. The tank housing in such a conventional system can include an air valve, such as a Schrader valve, to allow a user to recharge or pump up the pressure within the compressed air storage chamber. Such a conventional system can be converted to a source water driven system as described above by replacing the Schrader valve with a suitable adapter, to permit the attachment of a source water line 45 (See
