Abstract: A water heater system for a water dispensing fountain having a refrigerated water reservoir, is disclosed. The water heater system is comprised of a plastic molded hot water tank formed in a support membrane. A feed conduit is also formed in the membrane and extends from a connector, which secures to the bottom wall of the refrigerated water reservoir, to the bottom end of a serpentine array of the conduit which extends upwardly to the bottom wall of the hot water tank. The purpose of the serpentine conduit is to prevent hot water from the tank from flowing back into the refrigerated water reservoir. A dispensing conduit extends from the hot water tank and is located at a position whereby water can be extracted from a valve connected thereto by gravity flow. An exhaust pipe also extends from the hot water tank and is provided with an exhaust port located above the top water level of the refrigerated water reservoir whereby to exhaust water pressure vapors from the hot water tank.

Abstract: A filter adaptor assembly for a water cooler of the type having a support housing provided with a water bottle support at a top end to support an inverted water bottle over a water reservoir of the housing. The filter adaptor assembly comprises a support platform having a support base and it is connected in support engagement above the water reservoir. Supports are connected to the support base for securing one or more filter cartridges thereto. A dispensing valve is secured under the base and has a conduit for receiving treated water from the filter assembly. The valve has a water level sensing float mechanism which is adapted to detect the water level in the reservoir to dispense or cut-off the supply of treated water to the reservoir. The filter assembly is also connected to a pressurized water supply.

Abstract: A counter-height water dispenser which is comprised of a housing having a top wall disposed at substantially counter height. A water reservoir is supported in a top part of the housing. The reservoir has an open-top end section and a bottom cooling well section. The top wall is formed as a cover which is removably secured over an open area of the housing for access to an opening in the open-top end section of the reservoir. A compressor and condensor coil is mounted below the reservoir with a cooling coil being associated therewith. The cooling coil is disposed about the well section of the reservoir. An outlet port is provided in the well section and is connected to a low-pressure electric pump. The pump has an outlet tube connected to a dispensing faucet which is removably secured on the top wall of the housing adjacent the open area. The faucet has a low-pressure sealing coupling in its connection with the outlet tube.
