  • Patent number: 7228994
    Abstract: A delay flow water reservoir for a clothes dryer cabinet and method of use is provided. The delay flow reservoir has a container having an opening and a cap engaging the opening. The cap has a delay chamber with a drain opening, a seal covering the opening with first and second seal holes, and the delayed flow reservoir. The delay chamber fills with water from the container before draining into the clothes drying cabinets. The method of using the delay flow water reservoir permits the user to fill a container while in an upright position and then moving the delay flow water reservoir to an overturned dispense position. The method permits water to drain into the delay reservoir rather than out the drain opening while the user moves the reservoir into operational communication in the clothes drying cabinet.

  • Patent number: 7210182
    Abstract: Method and apparatus for recovering and purifying a solvent used in an article cleaning appliance are provided. The method allows passing solvent-based cleaning fluid from a wash basket through a coarse filter configured to remove relatively large particulates from the cleaning fluid. The method further allows passing cleaning fluid from the coarse filter through a particulate filter configured to remove relatively fine particulates from the cleaning fluid. An aqueous phase that may be present in the cleaning fluid is separated by decanting and coalescing through a separator/filter assembly. The cleaning fluid may then be passed through a regeneration cartridge for removing any water that may remain in the cleaning fluid, and for adsorbing organic contaminants that may be present in the cleaning fluid. Recovered solvent may be stored in a tank for subsequent use in a cleaning process performed by the appliance.

  • Patent number: 7191484
    Abstract: A laundry appliance comprises a drum for receiving a load of articles. The drum comprises at least two rotatable drum portions and a drive which is capable of rotating the drum so as to cause relative rotation between the drum portions. A controller monitors and controls operation of the appliance. The controller is arranged to determine when there is an overload condition on the drive during a period when the drum portions are being rotated relatively to one another and, in the event of an overload condition, causes the drive to operate in a manner that alleviates the overload condition. The drive can abort the current drum action and begin the next drum action in the sequence and, after a predetermined number of overload conditions, can suspend counter-rotating drum operation. The user may be provided with an indication when an overload condition occurs.

  • Patent number: 7162759
    Abstract: In order to be able to implement higher rotary spin speeds without structurally endangering the machine, a characteristic value that is as accurate as possible for the currently prevailing drum loading is desirable, for loading-dependent rotary speed limitation. Acceleration to a spin speed is interrupted in order to measure the respective electrical power consumption of the drive motor for a given rotary speed and then for a lower rotary speed that does not lead to the further removal of water from the laundry in the drum. Then the energy requirement and the acceleration period back up to the given rotary speed are measured, before the drum is accelerated to spin speed.

  • Patent number: 6924499
    Abstract: A device and a method for detecting deposits on surfaces includes a body having a surface on which deposits occur and influence reflection properties of the surface to electromagnetic radiation. A transmitter transmits electromagnetic radiation to the body and a detector detects the presence of the deposits at the surface. The detector measures electromagnetic radiation received from the transmitter after reflection at the surface. Preferably, the device and method are used in a liquid-conveying machine, particularly, a washing machine and/or a dishwasher. Particularly, light is introduced into the light-guiding body to detect the presence of the deposits. The light is internally reflected by the surface and is guided to a sensor. If deposits occur on the surface, the deposits affect the light-reflecting properties of the surface, and the affect is detected by the sensor.

  • Patent number: 6851148
    Abstract: A carbon dioxide dry cleaning system features a pair of liquid carbon dioxide storage tanks in communication with a compressor. A sealed cleaning chamber contains the objects to be cleaned. By selectively pressurizing the storage tanks with the compressor, liquid carbon dioxide is made to flow to the cleaning chamber through cleaning nozzles so as to provide agitation of the objects being dry cleaned. Liquid carbon dioxide displaced from the cleaning chamber returns to the storage tanks. In an alternative embodiment, a single storage tank is pressurized via a compressor with gas from the cleaning chamber so that liquid solvent from the storage tank travels to the cleaning chamber through nozzles. The objects in the cleaning chamber are agitated by a rotating basket. After a prewash cycle, liquid solvent from the cleaning chamber is directed to a still. The liquid solvent in the still is boiled through a connection with the head space of the cleaning chamber.

In a presently preferred embodiment, the automatic drum latch employs a floating latch bar which engages or disengages a latch strike attached to the drum door, depending on its orientation at the time the drum door is depressed and released. An actuator is utilized to perform the task of depressing and releasing the drum door at the proper times. When the lid of the machine is closed, the drum is rotated to a selected rotational position that determines whether the automatic drum latch will latch or unlatch after an actuator is extended to depress the drum door and then is released.

  • Patent number: 6775870
    Abstract: A method and system for dynamically balancing a rotating system, such that sensor measurements and responses to control actions can be compiled utilizing one or more sensors associated with the rotating system. The rotating system may be represented utilizing sensor measurements and responses to control actions through an associated control model, such that the control model and the sensor measurements are determinative of future control actions. The rotating system may be perturbed utilizing a control action while improving a balance condition associated with the rotating system. Sensor data may be measured from one or more sensors associated with the rotating system. Responses thereof may be determined based on the control action. The sensor data may be manipulated in order to remove measurements and responses thereof that do not well-represent the rotating system.
