Abstract: A filter manifold is provided in a water purification system and includes at least one filter element for producing relatively purified water, wherein the filter manifold incorporates a shut-off valve designed to prevent filter element removal unless the shut-off valve is first switched to a closed position for turning off the incoming water supply. The shut-off valve includes an elongated actuator lever which in a normal open position engages and retains a manifold latch plate in a latched position retaining the filter elements in connected relation with flow couplers to produce purified water. Upon movement of the actuator lever to a closed position shutting off the incoming water supply, the manifold latch plate can be unlatched from the filter elements to permit filter element removal and replacement.

The controller is adapted to receive and store water temperature information from the temperature sensor. The station preferably includes a display screen to display information from the controller and input means for the user to input information to the controller. The station can further include a modem so that the controller can communicate with a remote service center.

Abstract: An improved mounting adapter is provided for use in a bottled water cooler of the type having an upwardly open cooler reservoir for receiving a supply of water from a bottle mounted over the reservoir in an inverted orientation to permit water downflow from the bottle to the reservoir. The improved adapter includes a compact and substantially unitized adapter body or shell for removable snap-fit mounting onto the cooler reservoir at the open upper end thereof. The adapter additionally includes an upstanding feed tube or probe for operatively engaging a valved bottle cap mounted on the neck of a water-containing bottle supported in an inverted orientation over the cooler reservoir. In one form, the adapter may carry a seal ring gasket for sealingly engaging an inner wall surface of the cooler reservoir, and an air filter may be provided to filter ambient air drawn into the reservoir.

Abstract: A water cooler is provided with a removable reservoir separable from a cooler housing and transportable as a portable unit to a different location for remote dispensing of chilled water or other selected beverage. The removable reservoir comprises an insulated vessel having a dispensing faucet and adapted for removable mounting onto the cooler housing in thermal communication with a chiller element for maintaining the water within the reservoir in a chilled condition. The insulated reservoir is designed for quick and easy lift-off removal from the cooler housing and may include a convenient carrying handle to facilitate transport thereof to a remote location. In one preferred form, the removable reservoir supports an inverted water supply bottle for replenishing dispensed water, whereas in another preferred form the removable reservoir is adapted for receiving water inflow from a filtered tap water source or the like.

Abstract: A mounting adapter and related bottle cap are provided for use in a bottled water cooler having an upwardly open reservoir for receiving a supply of water from a bottle mounted over the reservoir in an inverted orientation to permit water downflow from the bottle to the reservoir. The mounting adapter comprises a compact housing for press-fit installation into an upper region of the reservoir, wherein the adapter housing carries an outer seal ring for sealing engagement with an inner wall surface of the reservoir. An upstanding feed tube or probe carried by the adapter housing includes separate air and water flow passages as described in U.S. Pat. No. 5,413,152, and has an upper tip end shaped for opening and closing a valved bottle cap mounted on the neck of a water-containing bottle supported in an inverted position over the reservoir. The bottle cap may be constructed, e.g., according to U.S. Pat. No.

Abstract: A water cooler is provided with an improved chiller system of the type having a thermoelectric chiller module for maintaining a supply of water at a reduced and refreshing temperature level. The chiller system comprises the thermoelectric chiller module having a cold side thereof in thermal communication with a supply of water to be chilled, and a hot side thereof exposed within a manifold defining a heat transfer chamber filled with a heat exchange medium such as water. An impeller located centrally within the heat transfer chamber circulates the water directly against the hot side of the thermoelectric module, from which the water then flows radially outwardly through a plurality of hollow fin elements and is recirculated back to the impeller. In the preferred form, the impeller is coupled by a hermetically sealed magnetic coupling to an air flow fan disposed outside the manifold for providing a cooling air flow over exterior surfaces of the hollow fin elements.

The float valve assembly is mounted within a reservoir for receiving and storing relatively purified water produced by the purification module, and includes a valve unit defining a vertically extending flow path from a tap water source to the purification module. A primary float carried on a float arm responds to rising and falling water level within the reservoir for respectively closing and opening a primary banjo valve mounted along the flow path. An over-center switch provides snap-action closure of the primary valve in response to rising water level, and the primary float is mounted on the float arm for a limited range of lost motion to accommodate this snap-action valve closure.
