Abstract

A program selector of an electronic programmer, e.g. of a washing machine, in which programs are stored in an integrated circuit store or memory, comprises two manual control switches and two display devices. One switch cooperates with selection circuitry cooperating with a numeric display device to increment a displayed number corresponding to a program number when the first switch is closed or to hold a selected program number displayed when the first switch is open. The second switch enables starting of a stored program corresponding to a displayed program number, the phases of the program carried out being displayed by a symbolic display device.

Claims

1. An electronic programmer having automatic program selection, comprising:

memory means for storing a plurality of instruction programs;

selecting means responsive to an input signal for automatically successively selecting respective ones of the stored instruction programs during the duration of the input signal;

first switching means for applying an input signal to said selecting means to implement successive selection of the stored programs;

read-out means responsive to an input signal and cooperative with said memory means and said selecting means for reading out the instructions comprising a selected program;

second switching means for applying an input signal to said read-out means to implement read-out of the selected program; and

display means cooperative with said selecting means and said read-out means for displaying which programs are successively selected during program selection and for continually displaying which of the plurality of programs has been selected after program selection has been completed and for displaying which of the program instructions is being read out.

2. An electronic programmer according to claim 1, wherein said memory means, said selecting means and said read-out means comprise a single integrated circuit.

3. An electronic programmer according to claim 1, wherein said first switching means includes a single manually operable switch operable for applying an input signal to said selecting means.

4. An electronic programmer according to claim 1, wherein said second switching means includes a single manually operable switch operable for applying an input signal to said read-out means.
