Abstract
(DE) Die Erfindung betrifft ein Haushaltsgerät (1) mit einem als BLDC ausgebildeten Antriebsmotor (4) zum Antreiben einer Komponente (2), mit einem Inverter (5) zur Ansteuerung des Antriebsmotors (4), wobei der Inverter (5) eine Motorsteuereinheit (7) zum Steuern der Drehzahl (n) des Antriebsmotors (4) aufweist und in zumindest zwei Betriebsmodi (M1, M2) betreibbar ist, die sich bezüglich der Steuerung der Drehzahl (n) voneinander unterscheiden, mit einem elektrischen Zwischenkreis (13) mit einem elektrischen Energiespeicher (8) zum Bereitstellen einer elektrischen Versorgungsspannung (UV) für die Motorsteuereinheit (7), und mit einer Steuereinrichtung (18), welche den Energiespeicher (8) mit einer Spannungsquelle (15) koppelt und von selbiger wieder trennt. Die Motorsteuereinheit (7) kann das Trennen des Energiespeichers (8) von und das Koppeln des Energiespeichers (8) mit der Spannungsquelle (15) erfassen und nach Erfassen des Koppelns einen der Betriebsmodi (M1, M2) abhängig davon auswählen, ob das Koppeln innerhalb oder nach Ablauf eines vorgegebenen Zeitintervalls (PZ) nach dem Trennen erfolgt.
(EN) The invention relates to a domestic appliance (1), comprising: a drive motor (4) designed as a brushless direct-current motor for driving a component (2); an inverter (5) for controlling the drive motor (4), wherein the inverter (5) comprises a motor control unit (7) for controlling the rotational speed (n) of the drive motor (4) and can be operated in at least two operating modes (M1, M2), which differ from each other with regard to the control of the rotational speed (n); an intermediate electrical circuit (13) having an electrical energy store (8) for providing a supply voltage (UV) for the motor control unit (7); and a control device (18), which couples the energy store (8) to a voltage source (15) and disconnects the energy store from said voltage source. The motor control unit (7) can detect the disconnection of the energy store (8) from and the coupling of the energy store (8) to the voltage source (15) and, after detecting the coupling, can select one of the operating modes (M1, M2), depending on whether the coupling occurs within or after the expiration of a specified time interval (PZ) after the disconnection.
(FR) L'invention concerne un appareil ménager (1) doté d'un moteur d'entraînement (4) réalisé sous forme de moteur à courant continu sans balais et destiné à entraîner une composante (2), d'un ensemble onduleur (5) destiné au pilotage du moteur d'entraînement (4), lequel ensemble onduleur (5) comprend une unité de commande de moteur (7) destinée à commander le régime (n) du moteur d'entraînement (4) et peut fonctionner dans au moins deux modes de fonctionnement (M1, M2) qui se distinguent l'un de l'autre par rapport à la commande du régime (n), d'un circuit intermédiaire électrique (13) comprenant un dispositif de stockage d'énergie électrique (8) destiné à fournir une tension d'alimentation électrique (UV) pour l'unité de commande de moteur (7), et d'un dispositif de commande (18), qui couple le dispositif de stockage d'énergie (8) à une source de tension (15) et le sectionne de celle-ci. L'unité de commande de moteur (7) peut détecter le sectionnement du dispositif de stockage d'énergie (8) vis-à-vis de la source de tension (15) et le couplage dudit dispositif de stockage d'énergie (8) à ladite source de tension et, après détection du couplage, ladite unité peut sélectionner un des modes de fonctionnement (M1, M2) en fonction du fait que ce couplage ait lieu au cours d'un laps de temps prédéfini (PZ) ou passé celui-ci après le sectionnement.
