A control system with a user configurable interface, particularly suitable for use in connection with appliances. Users can configure display screens either at a point of sale location or at home with, e.g., a personal computer.

Appliance control system with configurable interface

An electronic control for a cooking oven includes an input selection panel for receiving user input selections and control logic responsive to the input, selection panel for establishing a time and temperature profile of the oven cavity and for controlling heating devices according to the time and temperature heating profile entered by the user. The input selection panel includes heating function selection devices for receiving user selection of a heating function from among a plurality of heating functions and timing function selection devices for receiving user selection of at least one timing function from among a plurality of timing functions. The timing functions are independent of the heating functions so that a user may select any combination of timing functions with any selected heating function. The input selection panel includes labeled selection devices and labeled parameter display devices that define a grammatical sentence. The sentence emulates standard instructions in a cooking recipe. The functions and parameters selected by selection devices are laid out with the parameter display devices in a manner that functions are logically selectable from left-to-right across the panel.

Electronic input control for a cooking oven having independent selection

A method and apparatus for testing microwave ovens to determine if exterior radiation levels exceed permissible maxima. The leakage levels are sensed by a sensor moved along a preselected path accurately spaced from the oven cabinet. The probe is moved automatically at high speed along the path until a leakage level above a preselected value is sensed. A control associated with the apparatus automatically causes the sensor to move subsequently at a reduced speed to determine the maximum leakage at that position. The control causes a repeated traverse of the questioned position at the slow speed to provide an accurate maximum leakage determination. The control includes reference information indicating acceptable levels of leakage along the path of movement of the sensor which are continuously compared with actual sensed values. Different factors are applied to the reference values correlated with the speed of movement of the sensor and the desired coarse or fine scanning accuracy to permit the selective, high speed movement of the sensor between all high leakage positions. Information concerning the location of the high leakage positions is provided at the end of the test to permit facilitated correction of any leakage problems found. The control may further include structure for tagging the device being tested and for other suitable disposition thereof, as desired. The apparatus in the illustrated embodiment includes a robot for automatically moving the sensor along the desired path and an associated control for effecting the desired high speed-low speed movement in providing the rapid determination of high leakage positions.

Method and apparatus for testing microwave ovens

A sensing device for use in a control for an alarm indicating an undesirable operating temperature condition within a refrigeration apparatus cabinet. The sensing device is mounted to have at least one surface thereof in thermal association with a liner portion of the refrigeration apparatus cabinet defining a refrigeration chamber therein. The sensing device is further responsive to the temperature of the refrigerated air within the chamber. The sensing device incorporates a time delay in responding to temperature changes within the refrigerated chamber to avoid false operation of the alarm. The device may be mounted in an insulating housing to provide a further time delay in the air temperature sensing functioning thereof.
