  • Patent number: 6766670
    Abstract: The present invention relates to an automatic washing apparatus for dry laundering hanging garments. The automatic washing apparatus has a sealed wash cabinet and a working fluid storage chamber for storing an amount of working fluid sufficient to dry launder a fabric load. The working fluid storage chamber is in fluid communication with the sealed wash cabinet. The sealed wash cabinet has an interior region, an upper assembly above the interior region, a lower assembly housed below the interior region and a door sealing the interior region of the wash cabinet. The upper assembly shakes the hanging garments in the wash cabinet and dispenses a wash a working fluid into the wash cabinet. The lower assembly has a moisture generator and a heater to respectively generate moisture and heat inside the wash cabinet.

  • Patent number: 6763976
    Abstract: An anti run-on device is provided for use in a refrigeration appliance, wherein the refrigeration appliance includes a water dispenser including a water reservoir, a water conduit extending downstream from the water reservoir to a water spout, and a user operable valve positioned in the water conduit upstream of the reservoir and the water spout. The anti run-on device comprises a constriction in the conduit between the valve and the water spout, a small hole in the conduit located either at or just downstream of the constriction, and a vacuum chamber in communication with the small hole. A Venturi or knife edge effect is created when water is flowing through the conduit to evacuate the vacuum chamber, so that when the valve is closed, water between the small hole and the water spout is drawn into the vacuum chamber, thereby precluding dripping from the water spout.

  • Patent number: 6764702
    Abstract: A microwave oven and a method of processing frozen food in a microwave oven (1), which microwave oven comprises a microwave source (3), an oven cavity (2), and a control unit (5). The control unit is provided with an input signal containing information about the weight of the food, and causes the microwave source to feed microwaves at high average power into the oven cavity during a first time interval as well as a second time interval, which are separated by a waiting period, so that the foodstuff will be essentially thawed by the end of the second time interval.

  • Patent number: 6732447
    Abstract: A shoe drying device having two arms and an airflow channel extending therethrough. A spring exerts an outward force on the arms. Each arm includes a member for holding a shoe at an end thereof. During a drying cycle, convection air enters through an air inlet towards the center of the device, flows through the airflow channel, and exits through air outlets in the members for holding a shoe at the ends of the arms. This facilitates more even drying of shoes held in the members for holding shoes.

  • Patent number: 6734403
    Abstract: An oven and a method for controlling the ambient temperature in an oven comprising a baking cavity that is preheated with respect to a user-selected temperature set point. The baking cavity can include a rack for supporting a pan that conceptually divides the cavity into an upper heating region and a lower heating region. A broil heating element and corresponding broil temperature sensor are disposed in the upper heating region of the baking cavity. A bake heating element and corresponding bake heating sensor are disposed in the lower heating region of the baking cavity. A controlled is provided to control the activation of the broil and bake heating elements in response to the sensed temperature of the upper and lower heating regions to maintain the entire oven at a temperature substantially equal to a target temperature set point, which is determined based on the user-selected temperature set point.

  • Patent number: 6727449
    Abstract: The invention relates to a snap-in locking device for a multistage rotary switch with a switch spindle that is connectable with a rotary knob. The switch spindle is connected with an axle part that is snapped into an inner receptacle of a built-in switch panel part. The axle part rests on the switch panel part and is lock-in adjustable between snap-in receptacles with cams that are each limited by two radially-aligned connector links. The snap-in receptacles cover the entire circumference of the inner receptacle of the switch panel part. The axle part can be set into rotary motion with the switch spindle by a rotary knob, which is attachable to the switch spindle, and that modifiable limit stops define the number of switch positions, then a snap-in locking device for a operating unit is created with simple and cost-effective production and assembly parts that is coupleable with other components of the operating unit and can be equipped with an over-rotation safeguard.

  • Patent number: 6725680
    Abstract: A multi compartment refrigeration appliance is provided wherein each compartment is to be maintained at an independently selected temperature. The appliance includes a temperature selection input device for each compartment, at least one compressor, at least one evaporator, at least one fan for creating an air flow over the evaporator, a temperature sensor located in each compartment, and a control circuit to receive an input from said temperature selection input device for each compartment and a temperature signal for each temperature sensor and to produce an error condition signal with a magnitude dependent on a difference between the selected temperature and the sensed temperature for each compartment. The control circuit also controls a speed of the fan in response to a greater of the error condition signals.

  • Patent number: 6715175
    Abstract: A method and apparatus for predicting load unbalance in an appliance is provided for an appliance having a vessel configured to receive a supply of material and rotatable about an axis. A control is arranged and configured to rapidly accelerate a rotation of the vessel, determine an amount of energy with which the vessel has engaged the relatively stationary part, compare the amount of energy with a predetermined value and send a signal indicative of an unbalance condition if the amount of energy exceeds the predetermined value. The vessel may be rotated by use of an electric motor such as a controlled induction motor and the control can be used to measure the electric current drawn by the motor and through manipulation of the current, determine the amount of energy with which the vessel engages the stationary part of the appliance.
