Abstract
A digital clock device includes data storage units and produces switching signals in response to the data stored in accordance with predetermined functions, such as time of day and lapse of time. Switching signals responsive to quantities not related to time can also be produced. Data being stored is displayed as it is being entered into the device. In a disclosed embodiment, the device is used for the control of an electric range. Start of cooking time and duration of cooking for the oven and the individual heating plates can be controlled. Programmed control of oven temperature is also possible.
Claims18
An electronic digital time display apparatus comprising:
- display means;
- a time clock for the production of time signals;
- a display control circuit for control of said display means and responsive to said time clock to cause the current time to normally be displayed;
- a data input unit;
- means for storage of data entered in said data input unit and having at least one output terminal for the presentation of data stored therein;
- data input control means responsive to said data input unit for control of said data storage means, said data input control means being connected with said display control circuit and operative upon the initial entry of data into said data input unit to interrupt the display of the current time and cause the contents of said data storage means present at said output terminal to be displayed;
- a plurality of function storage units connected in common along a single data line with the output terminal of said data storage means;
- a plurality of function keys respectively associated with said function storage units for the assignment of data entered in said data input unit to a particular function storage unit;
- and
- function input control means responsive to said function keys for entering the contents of said data storage means present at said output terminal in the function storage unit associated with a function key upon actuation of said key and for terminating the display of data and causing the current time to be displayed on said display means upon deactuation of said key.
