  • Patent number: 6355177
    Abstract: A water filtering system for a refrigerator determines a need for a filter change by timing the period of actuation of at least one valve used to regulate the flow of filtered water to both a water dispenser and an ice maker. Based on a known flow rate, a volume of filtered water associated with the duration of valve actuation is calculated. A summing device determines an accumulated, filtered water volume. When the accumulated, filtered water volume reaches or exceeds a threshold value, an indicator is used to signal that the water filter needs to be replaced. As water filtering system of the invention is capable of being operated without a water filter in place, a switch assembly is incorporated to sense the presence of the water filter and the system only senses the valve actuation time when the filter is in place. In addition, provisions are made to reset the accumulated, filtered water volume upon replacement of the water filter.

An ultrasonic water level detector determines when the water level falls below the predetermined level and sends a signal to a controller which then opens the valved feed duct.

  • Patent number: 5707518
    Abstract: A water filter assembly mounted to an inner surface of a refrigerator and accessible from within a refrigeration compartment of the refrigerator. The filter assembly includes a first housing part, a second housing part, and a replaceable filter cartridge. The first and second housing parts cooperate to define a fluid-tight chamber for receipt of the filter cartridge. The first housing part includes an inlet port through which unfiltered water may be introduced into the chamber and an outlet port through which filtered water may exit the chamber. The second housing part surrounds a portion of the first housing part and provides a volume sufficient to hold the filter cartridge and any water within the chamber when the second housing part is released from the first housing part to replace the filter cartridge, and thereby prevents or minimizes spillage of water from the filter assembly during filter cartridge replacement.

  • Patent number: 5490547
    Abstract: A system for providing a constant supply of chilled fluid that includes a refrigerator cabinet having a refrigerated food storage area and a door. A serving vessel is removably located within the refrigerated food storage area. Fluid stored in the serving vessel is chilled while the serving vessel is in the refrigerated food storage area. The serving vessel also permits the fluid to be conveniently transported outside the refrigerated food storage area. A fluid supply system provides the fluid to the serving vessel via a dispenser located in the food storage area in response to outputs from devices that sense whether the door is closed, whether the serving vessel is at a specific location in the food storage area, and whether the amount of fluid is below a predetermined amount.

  • Patent number: 5263509
    Abstract: The utility conduits (electric conductors and water conduit) of a door mounted dispenser are conducted from below the cabinet to the inside of the door through an inflexible tube. One section of tube rests on a shelf under the refrigerator cabinet and a second section of the tube projects into the bottom of the door in free-standing relationship to the door. The lengths of the tube sections assure that the second section stays in the door without the need of any mechanical connection between the tube and door.

  • Patent number: 5135645
    Abstract: A water filter system for use in refrigerators having water dispenser and/or icemaker features. The filter system includes a commercially available filter cartridge which removes common water contaminants. A shut off valve temporarily stops the flow of water to the filter to permit replacement of the cartridge. The filter is disposed within the refrigerator for easy access and may be further disposed in a recess in one of the refrigerator walls or the refrigerator door to avoid reducing the useable food storage volume. The shut off valve may be closed by activating a conveniently located switch, by opening the refrigerator door, by opening a cover over the recess, or alternatively may be normally closed and opened only in response to activation of the icemaker or water dispenser features.

  • Patent number: 4571953
    Abstract: A small self contained refrigerator unit having a small water filtration unit in the refrigerator to provide filtered and cooled drinking water that is free from offensive odors and tastes, and is filtered to remove all offensive impurities. In thousands of business establishments and in homes the proprietors purchase bottled water, and have to contend with the inconvenience of lifting heavy bottles and periodically purchasing additional quantities of bottled water. By providing a small water treatment device in a refrigerator, the proprietor or homeowner is assured at all times of having cool good tasting water of better than bottle water quality for drinking and other purposes. It is unnecessary to open the refrigerator door to get drinking water because the delivery spout is conveniently located on top of the refrigerator which is low and provides a convenient work surface at table height.

  • Patent number: 4543800
    Abstract: The door-mounted water and ice cube dispenser of a refrigerator is supplied with chilled water and electrical power by a water conveying conduit and a plurality of electrical conductors which together pass through a hollow pintle and socket portion of a lower hinge assembly pivotally supporting the refrigerator door. To facilitate removal of the door from the associated refrigerator cabinet, the lower end of the conduit is connected to an end of a chilled water supply line by a union type coupling, the lower ends of the conductors being connected to a plug engageable with an associated power supplying socket fixed to the refrigerator cabinet. The conduit and conductors extend upwardly from the lower hinge assembly to the dispenser location via the interior of an elongated, rigid, tubelike member that isolates the conduit and conductors from any thermal insulating material or other obstructions filling the interior volume of the door.

  • Patent number: 3934757
    Abstract: A refrigerator is provided with a dispenser having a child-proof guard therewith for preventing the unwanted use of the dispenser. The refrigerator is connected to a fluid source and the cooled fluid is dispensed through a wall of the refrigerator. The dispenser is provided with structure for preventing unintended dispensing, and comprises a discharge spout located with reference to the wall of the refrigerator and adapted to discharge into a receptacle held in proximity thereto. Structure is controlled by movement of the receptacle and determines discharge or cessation of the discharge and includes a valve connected in the fluid source with structure for controlling the valve including a switch connected in circuit therewith. An actuating member is supported on the structure and cooperates with the receptacle to actuate the control structure which in turn includes structure movable selectively between a shut-off position and a discharge position.
