Definitions

  • the invention relates to a method for generating a low-voltage supply of an electrical control device and a low-voltage supply circuit of an electrical control device for carrying out such a method.
  • Such methods and supply circuits are used, for example, in domestic appliance technology, in particular for generating the low-voltage supply of an electrical control device of washing machines, dishwashers, etc., application.
  • the electrical control device is nowadays usually in the form of control electronics, for example as a microprocessor.
  • washing machines often have a sleep mode or a so-called standby mode to turn off the power consumers and recognize a reconnection.
  • the microprocessor or the electrical control device must also be connected to the power supply in standby mode.
  • the present invention is therefore based on the object to provide a method for generating a low-voltage supply of an electrical control device and a low-voltage supply circuit of an electrical control device for performing such a method, which further reduce energy consumption and yet meet the high standards of functionality and ease of use suffice.
  • This object is achieved according to the invention by a method for generating a low-voltage supply of an electrical control device with the features of Claim 1 and by a low-voltage supply circuit of an electrical control device with the features of claim 3 solved.
  • the first power supply can be deactivated, for example by switching off the clocking, so that the quiescent power requirement is very high in such a standby mode low or near zero.
  • the activation / deactivation input is connected by means of a low-voltage switch with a low-voltage switching signal leading low-voltage output of another (standby) power supply or disconnected from this. This ensures that the first power supply goes into a sleep mode with reduced power consumption when needed and can be activated by an operator in a normal (active) working mode, without the ease of use or functionality suffers.
  • the further power supply is designed as a capacitor power supply, so that the energy consumption in standby mode can be further reduced by its lower power consumption.
  • the low-voltage switch which is preferably operated manually by an operator, designed as a position, in particular rotational selection position, a program selector or integrated into this.
  • a program selector is also already available to control other functions in many devices.
  • Fig. 1 is a schematic diagram of a low-voltage supply circuit of an electrical control device according to the invention.
  • Fig. 2 is a schematic representation of a program rotary selector with a low-voltage switch in the form of a contact bridge.
  • the low-voltage supply circuit has a power supply unit, in particular a switched-mode power supply 1, which is connected on the primary side to a conventional power grid with phase L and neutral conductor N.
  • this switching power supply 1 is used to supply an electrical control device, not shown, for example, a microprocessor or microcontroller, an electrical consumption, such as a household appliance such as a washing machine, a dishwasher, a tumble dryer, etc.
  • the switched-mode power supply 1 has an activating / deactivating input E or an enable / disable input, which has a low-voltage switch 5 with a further one Power supply, in particular a capacitor power supply 3 is connected.
  • This capacitor power supply generates at its output A, a low-voltage switching signal S, which thus applied at the closed position of the switch 5 at the input E of the switching power supply 1. Due to the concern of the switching signal S at the input E, the switching power supply 1 can be switched to an active mode, ie normal working mode or by disconnecting the switching signal from the input E in an inactive mode.
  • the activation or deactivation of the switched-mode power supply 1 is in this case achieved, for example, by activating or deactivating the clocking customary for such a switched-mode power supply 1, so that when the clocking or other device of the switched-mode power supply 1 is deactivated, a very low quiescent current demand of almost zero is made possible. If now the switching power supply 1 are activated, it is sufficient to close the switch 5, so that the switching signal S, which is generated by the further low-energy power supply 3, applied to the input E of the switching power supply 1.
  • the input E is inverted, that is to say that when a switching signal is applied, the switched-mode power supply is deactivated and the switching power supply is activated by disconnecting the switching signal S from the input E.
  • the low-voltage switch 5 according to FIG. 1 can be designed as a contact bridge 5 'of a program rotary selector 6, the contact bridge 5' being conductively bridged in a certain position of the program rotary selector knob about its axis of rotation D perpendicular to the plane of the drawing or is closed. Furthermore, in Fig. 2 further contact bridges between lying on an inner race contact surfaces 7 and lying on a thereto outer web contact surfaces 9 are shown, which can be adjusted depending on the rotational position about the axis D of a program rotary dial by an operator and thus closed or operated.
  • the contact bridge 5 in addition to an already existing position or at least one further contact bridge or as an additional individual position.
  • the switch 5 or the contact bridge 5 ' only to one short-term supply of the input E to use with the switching signal S and after activation to open the contact 5 'and the switch 5 again.
  • the input E with a self-locking circuit, such as be connected by means of a flip-flop, wherein a shutdown can be realized by re-closing the contact and / or connecting the switching signal to another input of the switching power supply 1 and an upstream input circuit ,
  • the method according to the invention can also be implemented inexpensively, so that the advantage of reducing consumption costs outweighs a relatively small increase in production costs.

Abstract

L'invention concerne un procédé servant à générer un signal de mode veille pour un dispositif de commande électrique, notamment pour un dispositif de commande de lave-linge. Selon ce procédé, un premier bloc d'alimentation (1) est mis en mode actif ou en mode veille au moyen d'une entrée d'activation/désactivation (E) qui est reliée à un signal de commutation basse tension (S) ou en est déconnectée. Le signal de commutation basse tension (S) est généré, au moins en mode veille du premier bloc d'alimentation (1), en sortie d'une alimentation basse tension supplémentaire (3) et est relié à l'entrée d'activation/désactivation (E) du bloc d'alimentation (1) ou en est déconnecté au moyen d'un commutateur basse tension (5, 5'). L'invention concerne également un circuit d'alimentation basse tension (3, 5) d'un dispositif de commande électrique permettant l'exécution d'un tel procédé.
