  • Patent number: 7678202
    Abstract: A drip shield is mounted to a drawer of a drawer-type dishwasher so as to extend along an outer rear surface of the drawer and catch droplets of washing fluid falling from a lid of the dishwasher. The drip shield includes a shelf that extends between up-turned wall portions. The shelf is angled away from the tub so that any droplets of washing fluid that may fall onto the drip shield will migrate away from the drawer. The shelf is also formed such that first and second end portions are positioned higher than a central or intermediate portion. This construction forces the droplets of washing fluid to collect in a centralized drain point from where the droplets of water can be guided to a controlled location.

  • Patent number: 7670439
    Abstract: A dishwasher includes a pump assembly having a chopper blade and apertured plate arrangement which function to chop soil particles entrained in a flow of washing fluid. The chopper blade floats or axially slides relative to a drive member from a first position spaced from the apertured plate to a second position closer to the apertured plate in order to macerate the soil particles. The chopper blade is actually mounted to a hub member including a shaft portion that extends into and abuts an inner portion of an impeller to maintain a desired spacing between the chopper blade and the apertured plate, while transferring drive from the drive member to both the chopper blade and impeller.

  • Patent number: 7665475
    Abstract: A utility shelf includes a retaining frame pivotally connected to a support frame. The support frame is pivotally connected to a side portion of a dish rack through a plurality of hinge elements. Similarly, the retaining frame is pivotally connected to the support frame through a corresponding plurality of hinge members. The hinge members on the retaining frame are adapted to abut a stop member that positions the retaining frame at an angle relative to the support frame. With this arrangement, the retaining frame can be extended from the support frame to support objects during a washing operation.

  • Patent number: 7665810
    Abstract: A glass panel assembly for kitchen appliances includes a glass panel and a plurality of spacers. The spacers are mounted to an outer surface of the appliance and an inner surface of the glass panel. Preferably, the spacers are adhesively secured to the glass panel and are not visible when viewing the kitchen appliance from the front. Trim pieces fit between the glass panel and the appliance door to cover and further hide the spacers from view. The glass panel can be mounted to any outer surface of the appliance such as an appliance door, side walls or even a top wall. The particular construction of the spacers, in combination with the trim pieces creates an illusion that glass panel appears to float relative to the appliance.

  • Patent number: 7624745
    Abstract: A dishwasher includes a tub having a bottom wall and a plurality of side walls that collectively define a first washing chamber. The tub is supported in an outer, modular support body having first and second opposing side walls joined by a bottom wall, as well as a pair of upper frame members. In one embodiment of the invention, first and second support bodies are mounted one atop another to establish a dual drawer-type dishwasher, with the first and second support bodies being joined, preferably at a stepped interface region, by a plurality of brackets. The first and second support bodies are preferably aligned by arranging lugs formed on upper in-turned flanges on a lower support body within recesses formed in the bottom wall of the upper support body.

  • Patent number: 7621284
    Abstract: A dishwasher includes a filter chamber having a pressure relief system. The filter chamber preferably includes two drain ports, a first that leads to a drain line through a drain pump, and a second that leads directly to the drain line for over-pressure relief. The drain line is formed with a loop that establishes a pressure head. In the event that the filter chamber becomes clogged, a pressure build-up will occur. If the pressure in the filter chamber exceeds the pressure head in the drain line, a siphoning action will be automatically triggered that evacuates the washing fluid from the filter chamber. In this manner, the filter chamber can be purged through operation of the drain pump or, in the event of a clog resulting in an over-pressure condition, by siphoning the wash fluid directly into the drain line.

  • Patent number: 7607444
    Abstract: A dishwasher includes a drawer which is slidably mounted in a frame and forms a washing chamber. A lid assembly is mounted to the frame for selectively sealing the washing chamber during a washing operation. A closing mechanism moves the lid assembly from a first or open position to a second or closed position that provides a water-tight seal during a washing operation. The dishwasher is further provided with a latching mechanism including a pivoting door front member, a locking member and a linking bar interconnecting the door front member with the locking member. Manipulation of the pivoting drawer front member causes the locking member to engage/disengage with the lid assembly. The latching mechanism further includes a locking bar and a micro-switch that combine to prevent operation of the dishwasher if the drawer is not properly positioned in the frame.

  • Patent number: 7600388
    Abstract: A refrigerator incorporates an air filter for filtering an airflow passing along at least one refrigeration component into surrounding spaces. The air filter is positioned in an upper machine compartment which houses refrigeration components associated with maintaining temperatures in the refrigerator. At least one sensor is arranged adjacent the air filter to determine a parameter of the air flow. A control, including an air filter analyzer, determines a need for an air filter change based on the sensed parameter. In addition to removing impurities from the airflow, the air filter includes scented media which adds fragrance to the airflow.

  • Patent number: 7594413
    Abstract: An insulated icemaking compartment is provided in the fresh food compartment of a bottom mount refrigerator. The icemaking compartment may be integrally formed with the liner of the fresh food compartment, or alternatively, may be modular for installation anywhere in the fresh food compartment. A removable bin assembly with a front cover normally seals the icemaking compartment to maintain the temperature in the compartment. A cold air duct formed in the rear wall of the refrigerator supplies cold air from the freezer compartment to the icemaking compartment. A return air duct directs a portion of the air from the icemaking compartment back to the freezer compartment. An air vent with a damper in the icemaking compartment directs another portion of air into the fresh focm 8od compartment. A control system provides for controlling refrigerator functions in a manner that promotes energy efficiency, including movement of the damper between open and closed positions.

  • Patent number: 7587905
    Abstract: An icemaker system provided in a refrigerator is designed to reduce an amount of time required to produce ice. The refrigerator includes a refrigeration system including a number of refrigeration components and a refrigeration loop. The refrigeration loop includes an icemaker section that carries a flow of refrigerant to an ice mold portion of the icemaker system and a bypass section that isolates the icemaker system from the flow of refrigerant. A control system automatically activates the icemaker system regardless of a need for cooling. That is, upon sensing a demand for ice, the control system opens a valve to cause refrigerant to flow through the icemaker section and activates the refrigeration components to speed ice production whether or not additional cooling is required in fresh food and/or freezer compartments.

  • Publication number: 20090195136
    Abstract: An extending vertical wall is provided that secures to the rear edge of a shelf assembly inside a refrigerator compartment. The vertical wall comprises a vertical panel with two downwardly protruding legs. The legs removably reside within sockets included in the rear edge of the refrigerator shelf assembly. When the vertical wall is attached to the refrigerator shelf assembly, the vertical wall prevents items placed on the shelf from toppling off the back edge of the shelf assembly. At the user's discretion, the vertical wall may be quickly and easily removed from the shelf assembly. In an alternative embodiment, the wall is a formed retainer having an inserted U-shape such that the legs are received in the shelf sockets.
