Definitions
- a control circuit with timer function for an electric ⁇ al consumer appliance A control circuit with timer function for an electric ⁇ al consumer appliance.
- the invention relates to a control circuit for connecting an electrical consumer appliance to a sup ⁇ ply mains during an adjustable pre-determined time interval, comprising a relay switch, coupled into the supply line to the consumer appliance, the relay coil of which is activated and deactivated by means of a drive circuit with a timer function.
- the object of the present invention is to prov- ide a design of such a control circuit, which in a simple way provides the possibility of such a remote control without additional control wires between the remote control switch and the control circuit itself.
- the control circuit accord- ing to the invention is characterized in the relay activating signal provided at the output of the drive circuit is generated in response to a change of the voltage level of a toggle signal supplied to the drive circuit and generated by a pulse-shaping circuit con- nected to the supply mains in response to a brief interruption of the supply voltage, whereas means are associated with an adjusting unit for supplying oper- ating voltage to the drive circuit for maintaining the operating voltage during such a brief interruption.
- one or more remote control switches such as, e.g. spring loaded pressure couplers, can be placed in random positions along the supply line to the consuming appliance.
- connection terminals for the consuming appliance e.g. an elect- rical drive motor for a fan
- 3 and 4 designate connection terminals for the supply voltage
- 5 is a pressure coupler, by means of which the supply volt ⁇ age can be disconnected during a brief time interval.
- a relay switch 7 is coupled into the supply line 6, the activating coil 8 of which is connected to an output REL from a drive circuit 9.
- the drive cir ⁇ cuit 9 is of the type having a built-in timer funct ⁇ ion, which is made adjustable by means of an RC cir ⁇ cuit 10 connected to an input OSC, and having a capac- itor C 3 , a fixed resistance R-. and a potentiometer P..
- the drive circuit 9 is activated by means of a toggle signal supplied to an input TOG, for example so that the signal at the output REL changes level each time the toggle signal on the input TOG drops below a cert- ain level, whereby the timer function is reset at zero.
- the relay 8 is activ ⁇ ated, the switch 7 of which is maintained connected during the connection time determined by the RC cir- cuit 10.
- the supply voltage supplied to the terminals 3 and 4 is double rectified by means of the diode cir ⁇ cuits DI, D3, D4 and D9 and is reduced to a voltage level of, e.g. 24 V by means of the circuit R8 D5, Tl supplying the relay coil 8.
- the reduced 24 V voltage which is decoupled by a capacitor C6 is peak rectified in the circuit D2 C5 and series regulated by means of a regulator cir ⁇ cuit 11 to a level of, e.g. 5 V.
- a capacitor C5 of, e.g. 1000 ⁇ F serves to maintain the input voltage to the regulator circuit 10 at interruption of the supply voltage during a brief time interval, e.g. up to 5 seconds.
- the operating voltage for the drive circuit 9 is taken from the output of the regulator circuit 11.
- the regulator circuit is further arranged so that when the supply voltage is reestablished after an interruption of a longer duration, it produces a RESET signal at the output. This signal, the pulse width of which is determined by a capacitor C4, is supplied to a separate input ON on the drive circuit 9 and ensures that it always activates the relay 8, when the operat ⁇ ing voltage has been interrupted (cold start) .
- the toggle signal to the input TOG of the drive circuit 9 is generated either by a brief activation of the pressure coupler 5 in the supply line or by activating a separate switch 12. In both cases a pulse-shaping circuit 13 connected to the supply main is affected.
- the coupler 5 When the coupler 5 is closed and the switch 12 is off the input voltage will, through the double rectifier diodes D6 and D7 and the resistances R6 and R4, generate a direct current of, e.g. 6.2 V over the diode D12.
- the coupler 5 If the coupler 5 is opened, whereby the supply voltage is interrupted, or the switch 12 is connected, the voltage over the diode D12 will de- crease, whereby the transistor T2 will conduct and charge the capacitor C7 to a voltage level of, e.g. 5 V.
- the diode D13 As soon as the voltage over the capacitor C7 has risen above a certain lower level, e.g. 2.5 V, the diode D13 will conduct, and thereby the toggle signal on the input TOG will be dragged below the change-over level, e.g. 1.6 V.
- the toggle input TOG in commercial embodi ⁇ ments of the drive circuit 11 e.g. like the circuit U 6047 B marketed by Telefunken Elektronic, is bounce protected so as to only react to pulses with a larger width than approx 1/12000 of the actual timer setting, which for example may be up to 60 minutes
- the struct ⁇ ure of the pulse-shaping circuit is arranged so that such a pulse width is ensured by a built-in time con ⁇ stant of, e.g. 0.5 seconds for the trailing edge of the voltage over the diode D13. If the switch 12 is activated during a time interval shorter than, e.g.
- the transistor T2 will block, as soon as the voltage over the diode D12 reaches a level of, e.g. 4 V.
- the time delay occurs because the voltage over the capacitor C7 is discharged slowly through the resistance R3, and only when it reaches the afore ⁇ mentioned level of, e.g. 2.5 V, the diode D13 will block and the level of the toggle signal on the input TOG will assume its high level.
- the resistance R4 serves to protect the switch 12 against the peak voltage when the capacitor C2 is discharged. If the adjusted 5 V voltage from the cir- cuit 11 has been disconnected the capacitor C7 is dis ⁇ charged through the diode D8 which ensures that the toggle function is activated immediately at reestabl- ishment of the supply voltage at cold start.
- the dio ⁇ des D10 and Dll protect the circuit against voltage transients from the motor and the relay coil.

Abstract
Circuit de commande assurant la liaison d'un appareil consommateur d'électricité à l'alimentation du secteur pendant une période prédéterminée et réglable. Le circuit comprend un commutateur relais (7) couplé dans la ligne d'alimentation (6), à l'appareil consommateur, dont la bobine de relais est activée ou désactivée par un circuit d'attaque (9) avec une fonction de temporisation. Le signal d'activation du relais est délivré à la sortie du circuit d'attaque, il est généré en réponse à un changement dans le niveau de tension d'un signal de basculement communiqué au circuit d'attaque (9) et généré par un circuit de mise en forme d'impulsions (13) connecté au secteur en réponse à une brève interruption de la tension de sortie. Un dispositif (C) est associé à une unité de réglage (11) pour l'alimentation en tension de fonctionnement du circuit d'attaque, aux fins du maintien de la tension de fonctionnement pendant cette brève interruption.
