Definitions

  • the present invention relates to timing control apparatus suitable for controlling equipment to which the timing control apparatus belongs.
  • Timing control apparatus often form part of the control system of domestic equipment, such as domestic cookers, and are arranged to provide an indication of the time of day and to accept and execute instructions resulting in the equipment being switched on at a specific time, or at specific times, for a specific duration, or for specific durations.
  • Timing control apparatus fitted to equipment reduces the need for a user to supervise the equipment but the increased ease of operation is generally accompanied by an increased difficulty in maintaining the equipment in a working state.
  • the present invention provides timing control apparatus which includes a self-test capability for facilitating maintenance of the timing control apparatus and equipment to which the timing control apparatus belongs.
  • timing control apparatus includes timing data storage means, control data storage means and logic means for effecting the operation of the timing control apparatus control means operable to effect the entry of timing data into the timing data storage means, display means for displaying the timing data, and output means providing output signals for controlling equipment to which the timing control apparatus belongs, the timing control apparatus be so arranged as to go into a self-test mode on the operation of the control means under predetermined conditions.
  • Timing control apparatus is such as to go into a self-test mode on the operation of the control means as the apparatus is being energised.
  • the timing control apparatus may, with advantage, be so arranged as to execute a set test routine in the self-test mode.
  • a set test routine may, for example, result in the display of a set sequence of timing data.
  • the timing control apparatus may be so arranged that, in the self-test mode, energisation of selected parts of the display means are effected by control means.
  • timing apparatus self-test routine The maintenance of equipment to which the timing control apparatus belongs is facilitated by the use of the timing apparatus self-test routine.
  • Timing control apparatus in accordance with the present invention, will now be described, by- way of example only, with reference to the accompanying block diagram representation of the apparatus.
  • the timing control- apparatus is intended for controlling a domestic cooker and includes five push-button control members 4, 5, 6, 7 and 8, housed in a cover member 2 which has a window 3 through which four seven-segment and other display devices are visible.
  • the apparatus includes a buzzer (not shown).
  • the timing control apparatus also includes a digital signal generating and processing circuit 1, known more generally as a microprocessor, which includes timing data storage means, control data storage means and logic means, and output means for providing control output signals.
  • the digital signal generating and processing circuit 1 is connected to switch contacts operable by means of the push-button control members 4, 5, 6, 7 and 8 by way of a first group of connectors 10 and a part 12 of a second group of connectors 9.
  • the digital signal generating and processing circuit 1 is connected to the display devices by way of a third group of connectors 11 and a part 13 of the second group of the connectors 9.
  • the interconnection of the switch contacts, referred to above, the first group of connectors 10, and the part 12 of the second group of connectors 9, is such as to form a cross-point switch matrix in which closure of one of the switches effects connection of one of the connectors 10 with one of the connectors of the group 12.
  • the digital signal generating and processing circuit 1 is so arranged as to scan across the connectors of . the group 12 with pulses, and to recognise which of the switch contacts is closed by the time of return of one of its pulses on one of the connectors 10 when a switch contact is closed.
  • the digital signal generating and processing circuit 1 is arranged also to scan across the connectors of the group 13 to energise each display device in turn while applying to the segments, in synchronism with its scan pulses, data representative pulses, for effecting data display.
  • the five push-button control members 4, 5, 6, 7, and 8 control respective switch contacts recognised by the digital signal generating and processing circuit 1 as follows:-
  • the digital signal generating and processing circuit 1 is so arranged as to check the condition of the switch contacts associated with the MANUAL push button 4 immediately after the timing and control apparatus has being energised, and to go into the self-test mode if the switch contacts are closed.
  • control data storage means and logic means controls the display devices to provide the following sequence:-1.
  • the right-hand digit of the display is energised to display zero and then to display all values up to eight.
  • the apparatus is further controlled by the control data storage means and logic means to permit energisation of the display digits by the operation of respective ones of the push-button members as follows:-1. Operation of the push-button 5 results in the energisation of the right-but-one digit to display the value four.
  • the timing and control apparatus is returned to its normal mode by de-energising it and re-energising it without operating the MANUAL push-button 4 at the time of re-energisation.
  • the timing and control apparatus is operative to accept push-button controlled input timing data representing "time of day”,”cook time” and “ready time”. Alternative arrangements including “start time” may be used.
  • the timing and control apparatus in the normal mode, is used as follows for the entry of "cook time", say:-
  • the push-button 6 is operated to select "cook time” as the timing data for entry and the apparatus will display zero value cook time, (Any previously entered “cook time” will have been replaced by a zero value immediately after energisation, in known manner).
  • the push-button 6 is held in the operated condition and after a delay the display will show that "cook time” is incrementing.
  • the push button 6 is held until the displayed value "cook time”is equal to the desored "cook time”. Should the entered value of "cook time" overshoot the desired value, the push-button 8 is operated to decrement the value of "cook time". There is no delay between the operation of the push-button 8 and the decrementing of the displayed value of "cook time”.
  • timing data entry push buttons perform the dual functions of indicating which timing data is to be entered and of incrementing the value for the data.
