Abstract: An illuminating device for an appliance is provided. The illuminating device is in communication with a sensor that measures an environmental condition. During operation of the appliance, the illuminating device is continually operated at a light level greater than or equal to a minimum light level. Preferably, the light level of the illuminating device is adjusted based upon measuring or detecting an environmental condition.

Abstract: An appliance is protected against ground faults by a ground fault interrupter (GFI) that sends a signal to an AND gate between the GFI and a controlling microprocessor on one side and a load relay for operating a load device in the appliance on the other side. The GFI signals a ground fault directly to the load relay causing it to deactivate the load device. The appliance is also protected against reverse polarity by a flow detector circuit that signals the load relay to deactivate the load device in a reverse polarity condition.

Abstract: The invention relates to an automated liquid dispenser employing ultrasonic sensing to determine the level of a dispensed liquid with respect to the height of a container to be filled. In one aspect, the invention relates to a refrigerator with an automated liquid dispenser that utilizes ultrasonic sensing.

Abstract: The present invention relates to a control device for a household electrical appliance. The control device has an interface configured to enable a user to set or modify parameters of one or more operational members of the appliance by a command and control circuit in communication with the appliance. The interface has a one or more selectors arranged to enable setting or modifying of the parameters of the appliance. The selectors are connected to a resonant electrical circuit arranged to generate or to respond to a radio-frequency signal in a modifiable manner representative of the setting or modification effected by the user. The signal also being sensed by a sensor associated with the command and control circuit, which enables the command and control circuit to set or modify in an appropriate manner the parameters of the operational members for controlled operation of the household electrical appliance.

Abstract: A condition sensor for a fabric treating apparatus, such as a clothes dryer. A condition sensor is connected to a base wherein the condition sensor is operative to sense a condition such as moisture content for a multi-layered load placed within the dryer. The condition sensor comprises at least one support connected to the base wherein the at least one support has at least one extension attached thereto. A pair of capacitance sensors are attached to the at least one extension with the pair of capacitance sensors being arranged to build up charge through the condition sensor based on the moisture of the load content positioned in the dryer. A circuit is arranged to receive, read and generate signals in response to the charge of the capacitance sensors.

Abstract: A method and apparatus is provided for operating a self-cleaning oven in which a gas sensor, such as for measuring concentrations of CO gas, is located remote from, yet in gas communication with, an exhaust flue of the oven. The gas sensor is located at the end of an outlet tube which extends from the exhaust flue. A sample gas flow is provided to the gas sensor through the outlet tube to isolate the sensor from the heat of the oven and a filter device is located in the outlet tube for filtering the sample gas flow. A valve may be provided at the inlet to the outlet tube. The rate of change (slope) of successive readings of gas concentrations may be used to determine when the combustion of food material is complete, in order to terminate a self-cleaning cycle.

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.

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.

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.
