A refrigerator includes a first storage compartment defining a first interior volume. A first evaporator is configured to cool air that flows past. A first plenum includes a first air outlet, a second air outlet and a first air inlet disposed between the first and second air outlets. The first air inlet is configured to receive air into the first plenum from the first interior volume. The first plenum is configured to flow the air received in the first air inlet over the first evaporator to cool the air. The first and second air outlets are configured to flow the cool air from the first plenum into the first interior volume.

A control system is provided for a washing machine including a cabinet, a wash tub positioned within the cabinet and a wash basket rotatably mounted within the wash tub. The control system includes a plurality of supports including two diagonally arranged supports. The plurality of supports are configured to support the washing machine on a surface. At least one load sensor is positioned with respect to each support of the two diagonally arranged supports. The at least one load sensor is configured to detect at least one force component applied to each support by a load within the wash basket. The at least one load sensor is further configured to generate a signal representative of the at least one force component. A controller is in signal communication with the at least one load sensor. The controller is configured to detect an operating load placement condition within the wash basket in response to at least one signal received from the at least one load sensor.

An automated cooking system () cooks food () accompanied by machine-readable indicia, such as a bar code () read by a reader (). Cooking data, including function coefficients, are accessed from an Internet server () based on the information in the bar code. An oven () cooks the food in phases in response to the cooking data and one or more monitored food parameters of humidity, temperature and weight. The cooking is controlled by functions in which one or more food parameters are multiplied by coefficients that vary according to food type.

Appliances ( and ) are controlled by providing a source ( ) of command fields (CMD, FIG. ) that include a context subfield (Community, FIG. ) defining operating modes and a command subfield (Command, FIG. ) defining operations to be performed within the context subfield. A network ( ) transmits the command fields between the source and the appliance. A controller ( ) processes the command fields so that an operation defined by one of the command subfields is performed.

An apparatus and method for defrosting an evaporator of a refrigeration sealed system is described. The system includes a controller operatively coupled to an evaporator fan, a condenser fan and a defrost heater, and the method includes operating the sealed system until a selected time till defrost interval expires, initiating a defrost cycle when the time till defrost interval expires, and selectively operating the sealed system to raise a temperature of the evaporator while the defrost heater is inactivated.

An apparatus and method for controlling a sealed system including a variable speed compressor coupled to a controller is described. The method includes establishing a control grid having at least one axis corresponding to a temperature at a specified location, and the axis is divided into a plurality of operating states of the sealed system. Each of the states correspond to a sensed temperature condition at the specified location, and each of the states includes a designated compressor speed parameter. The compressor speed parameter in some of the states is different from the compressor speed parameter in other of the states.
