Data entry and control arrangement for an appliance

A data entry and display control arrangement comprising:

• electronic display means comprising a plurality of digits including a least significant digit and at least one higher order digit for displaying numerical operating data;
• data entry means comprising a plurality of user actuable keys including an up key and a down key;
• display control means responsive to said data entry means for controlling said electronic display means;
• said display control means including display update means operative in response to actuation of said user actuable keys to periodically update said display at a predetermined update rate, the period between successive updates defining an update interval;
• said display update means comprising means responsive to actuation of one of said up or down keys to change said least significant display digit by one unit at the first display update following key actuation, and operative to set said least significant digit to zero and change the next higher order digit by one unit at the end of each succeeding update interval as long as said up or down key remains continuously actuated, whereby said display value changes by one unit in response to each momentary actuation of said up or down key and displays a value evenly divisible by ten which changes in ten unit increments at a predetermined update rate in response to continuous actuation of said up or down key.

A data entry and display control arrangement comprising:

• electronic display means including a plurality of digits including a least significant digit and at least one higher order digit for displaying numerical operating data;
• data entry means comprising a plurality of user actuable keys including first and second function keys, an up key and a down key;
• display control means responsive to said data entry means for controlling said electronic display means;
• said display control means including display update means operative in response to actuation of said user actuable keys to periodically update said display digits at a predetermined update rate, the period between successive updates defining an update interval;
• said display update means being operative in response to actuation of one of said first or second function keys and one of said up or down keys to increase or decrease respectively said display by a first amount upon the next occurring update, and to set said least significant digit to zero and increase or decrease said display respectively by a second amount evenly divisible by ten, at each subsequent update as long as said up or down key remains continuously actuated.
