摘要:
An appliance controller includes a plurality of LEDs that are configured annularly about a control knob of the appliance controller. The LEDs are operated so as to indicate status of the operation of the appliance when the appliance is in a run mode. In one form, the appliance controller illuminates one of the LEDs to indicate at what point the appliance is in its cycle of operation. When the appliance is in a stop mode, the LEDs are operated to indicate where the control knob is positioned when a user is selecting a particular operation with the appliance controller. In one form, as a user rotates the control knob, the appliance controller determines the rotational or angular location of the knob, particularly via a selection indicator of the knob, and illuminates a corresponding LED.

An apparatus includes a controller for controlling operation of an appliance, an indicator light coupled to the controller to provide a visible indication of an operator selection in response to the controller energizing the indicator light, and a driver coupled to the controller and the indicator light so that the controller may communicate data through the indicator light by controlling the driver. The indicator light may be a light emitting diode or a segment of an alphanumeric display of an appliance control panel. A detector LED may also be coupled to the controller so the controller may receive data from an external device that communicates by flashing light on the detector LED. A terminal for communicating with the appliance may include a detector LED and a conductor that couples the detector LED to a diagnostic tool. The detector LED may receive data from an optical transmitter of the appliance control panel. The terminal may also include a LED that is coupled to the diagnostic tool by a conductor so the LED may be selectively energized by the diagnostic tool to communicate with an optical receiver of the appliance control panel. The detector LED and LED coupled to the diagnostic tool may be located within a housing having apertures for the transmission of visible light to and from the detector LED and LED. The housing may be mounted to the appliance control panel and aligned for communication by means of a magnet or engagement with supports on the appliance control panel.

An appliance controller includes a plurality of auxiliary inputs for adjusting parameters of appliance operation such as washing machine operation (e.g. water temperature, rinse options, water level, speeds and/or the like). Each auxiliary input unit acts as a low power potentiometer. The various auxiliary units are connected in series. Each auxiliary unit produces a variable resistance based on position of a control knob of the auxiliary unit. The auxiliary inputs cooperate with each other to produce a unique aggregate resistance signal for the particular arrangement of users knobs of the various auxiliary input units. This unique resistance signal is sent to the processor thereby providing user selection information relating to the various auxiliary input units to the processor. In one form, each auxiliary input unit requires only two wires thereby eliminating a substantial amount of wiring. In one form, a detent plate and associated grooves is provided to simulate tactile feedback experienced when a traditional appliance input knob is rotated.

An apparatus includes an appliance control panel and a controller. The appliance control panel is disposed on an appliance. The appliance control panel has first and second optical communication devices that are in communication with an external surface of the appliance control panel. The controller is secured within the appliance. The controller is operably connected to the first and second communication devices to provide communication signals thereto, the communication signals including diagnostic information.

An appliance includes a rotating position switch (32) and a selector switch (34). The rotating position (3A-3F) switch has a first position (4A-4D) associated with a first appliance function and a second position associated with a second appliance function. The second appliance function modifies the first appliance function. The selector switch (34) has an actuated state configured to generate a signal representative of a selection of the first appliance function when the rotating position switch (32) is in the first position. The actuated state is further configured to generate a signal representative of a selection of the second appliance function when the rotating position switch (32) is in the second position.
摘要:
The present invention provides a control system for a heating unit in a cooktop that is capable of detecting the presence (or absence) of a cooking pan or utensil. The heating unit has a spirally wound ribbon heater element and may be mounted below a glass-ceramic cooking surface. The control system includes a pan detection unit electrically connected to the heater element. The pan detection unit generates a high frequency signal through the heater element to determine whether a pan is present on the cooktop. The pan detection unit may have an oscillation circuit to generate the high frequency signal through the heater element. In one embodiment, the control system further includes at least one switch device that is connected between element and the power source. The switch device is opened to remove the heater element from the power source when the pan detection unit generates the high frequency signal through the heater element. The present invention also includes a heating unit having dual heater units to determine the size of the pan placed on the cooktop. The present invention further includes methods of operating a heater unit and control system having the capability of detecting the presence of a pan.
