Data entry and control arrangement for an appliance
First Claim
1. A data entry and display control arrangement comprising:
- electronic display means having 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;
said display control means including update means for periodically updating said display at regular update intervals of predetermined duration, in response to actuation of said up or down key;
said update means being operative to increase or decrease said display by a first amount in response to each initial actuation of said up or down key respectively, and to switch said least significant digit to zero and thereafter increase or decrease said display by a second amount, evenly divisible by ten at the end of each succeeding update interval as long as said up or down key remains continuously actuated, whereby the display is changed in relatively small increments when an up or down key is momentarily actuated and in larger increments with the displayed values evenly divisible by ten when an up or down key is continuously actuated.

Abstract
An improved data entry and control arrangement for an appliance which includes an electronic display having a plurality of digits. User actuable up and down keys enable the user to adjust the value displayed. The control changes the display by a first amount, for example, one minute for a time display, in response to each momentary actuation of an up or down key. In response to continuous actuation, the control, after initially changing the display by the first amount, then switches the least significant digit of the display to zero and thereafter periodically changes the display by a second amount evenly divisible by ten, such as for example 10 minutes. The preferred update interval between changes is on the order of 0.45 seconds duration. The control also enables the user to change the update interval.

9. 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. - View Dependent Claims (10, 11, 12, 13)

14. 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. - View Dependent Claims (15, 16, 17, 18, 19, 20)
