The invention aims, among other things, the Ueber ^ aag from

To accomplish the d ^ ülzyiclen seluatätig has the characteristic that when starting the rtasohprograaima at least one switch is energized, through which a capacitor of the first time circuit is connected to a storage voltage, whereby aieae time circuit has a switch in series with the FtIllffleοhanIsmus washing machine 3chliesst _t while after the induced by the second timing circuit being the connection between the capacitor and the 3peise ₆ facilitated voltage is interrupted, so that after a conditional by the first timing circuit delay time of the ichalter off in series with the Füllmechaniamus.

After a period of time determined by the second timer Preferably another switch in series with the filling mechanism interrupts the connection between the filling mechanism and the supply voltage, and establishes the connection between the filling mechanism emptying pump and the supply voltage lter.

In particular, a switch forms part of an I / _O controller that supplies the DC supply voltage of the temperature-controlled circuit in such a way that in the unexcited state of this switch the output flow of the circuit is interrupted, "0" by the connection between a capacitor in the input circuit of the second timing circuit and the operating voltage is interrupted.

According to a favorable embodiment, the series switching is located the switch that is excited when the program is started, the Eleaentee that maintains the excitation, the temperature-controlled switch circle and further in series with the filling mechanism Switch on the DC voltage.

As a result, the current through the relay coil 99 increases and the two-pole switch 62, 21 assumes the position shown by a dashed line 'the voltage source 1 is connected' i) the pump motor stops; the light source 23 is ignited after the light-sensitive resistor 24 has been bridged by means of the deu ütartknopfes 22 · This V / resistance is illuminated by the light source 25 and thus no more resistance ·

The light-sensitive resistor 45, which is also illuminated by the light source 2J, becomes low-resistance, so that the capacitor 46 located in the initial direction of the time serial device 4Θ is charged. Let the capacitor 46 be charged to such an extent that the base voltage of the NPN Traneistore 52 exceeds the emitter voltage as a result of charging, the transistor 52 becomes conductive and the NPN transistor 57 begins to block ie 20 comes to the position shown in dashed lines.

The switch 21 reaches the Position represented by a solid line. This has two poles

First, the pump motor 26 comes back into operation, so that the carrion bucket is pumped empty.

Second, the source 2J is briefly shot. The first consequence of this is that the light-sensitive resistor 45 goes high, so that the capacitor 46 located in the input circuit of the timer circuit 48 is no longer charged and slowly begins to discharge via the resistor 47. Secondly, the in-i »usgan _b sicreis the timing circuit 48 liohteicpfindliche resistance becomes high impedance so that the current-conducting parallel to rteihensuhaltung of photosensitive resistors bO and 61 lying relay coil 62 * / IRD and the switch 20 assumes the large shared aurch a broken line ¹ position.

The filling valve 3 is then over the closed switch 20 and the switch 21 in the by a dashed line Line shown position connected to the voltage source 1. The wash tub is filled again up to the level in which the level regulator 19 bridges the contacts H and 33. When bridging contacts L and 31 by the switch 164 in the level regulator 19 becomes the light-sensitive one Resistance 61 due to ignition of the light source 4 although low " but the light-sensitive resistor 60, which is in series with the resistor 61, has a high resistance, so that the Relay coil 62 remains energized.

In the circuit diagram after Piff. 3 is the series connection of the light-sensitive resistors '16 * 0 '* - and 161 in the input circuit of the Timing circuit 48 una directly between the base electrode of transistor 52 and the negative voltage terminal.

If the switch 207 is opened, the contents of the wash tub are heated during the pre-wash. 3) At the end of the Voxwaschzyklusses the switch 164 Ib level regulator 19 relays in the position in which the contacts 31 and 32 are bridged. This occurs suddenly, so let a voltage pulse be supplied to the anode of the gas discharge lamp 122 via the resistor 209 and the capacitor 210, since the insensitive resistance 218 illuminated by the gas discharge lamp 220 is of low resistance.
