Description

Die Erfindung bezieht sich auf eine programmgesteuerte Waschmaschine mit Warm- und Kaltwasseranschluß, bei der zur Steuerung der Warm- und/oder Kaltwasserzufuhr in der Warm- und Kaltwasserleitung je ein Ventil angeordnet ist und im Laugenbehälter ein den Flüssigkeitsstand erfassender Niveauschalter vorhanden ist.The invention relates to a program-controlled Washing machine with hot and cold water connection, for the Control of the hot and / or cold water supply in the hot and cold water pipe a valve is arranged and in Suds container which detects the liquid level Level switch is available.

Waschmaschinen mit Anschlüssen für kaltes und warmes Frischwasser sind allgemein bekannt. Die Leitungen für die Kalt- und Warmwasserzufuhr werden von Elektromagnetventilen beherrscht. Dem Laugenbehälter ist ein Niveauschalter zugeordnet, der den Wasserzulauf bei Erreichen eines bestimmten Füllstandes unterbricht. Der Zulauf des Frischwassers erfolgt in der Weise, daß das Kalt- und das Warmwasserventil unabhängig voneinander kaltes bzw. warmes Wasser in den Laugenbehälter einlassen. Je nach gewähltem Waschprogramm wird entweder nur das Kaltwasserventil oder nur das Warmwasserventil oder beide Ventile gleichzeitig angesteuert. Bei letzterem fließt dann die doppelte Wassermenge zu. Ist darüberhinaus den beiden Ventilen noch ein Mengenregler nachgeschaltet, so kann die insgesamt dem Laugenbehälter zufließende Wassermenge entsprechend reguliert werden.Washing machines with connections for cold and warm Fresh water is well known. The lines for the Cold and hot water are supplied by solenoid valves controlled. There is a level switch in the tub assigned to the water inlet when reaching a certain level interrupts. The inflow of the Fresh water takes place in such a way that the cold and Hot water valve independent of cold or warm Let water into the tub. Depending on the chosen one Washing program is either only the cold water valve or only the hot water valve or both valves at the same time controlled. The latter then flows twice Amount of water too. In addition, the two valves are still a volume regulator connected, so the total The amount of water flowing into the tub accordingly be regulated.

Der Erfindung liegt die Aufgabe zugrunde, bei Waschmaschinen der in Rede stehenden Art die Warm- Kaltwassersteuerung weiter zu verbessern und den Gebrauchswert solcher Waschmaschinen zu erhöhen.The invention is based on the object Washing machines of the type in question the warm Cold water control further improve and To increase the utility value of such washing machines.

Die Lösung dieser Aufgabe gemäß der Erfindung besteht darin, daß zu Beginn des Waschprogrammablaufs während einer festgelegten Zeitspanne ausschließlich das Warmwasserventil geöffnet ist und daß bei Nichterreichen eines vorgegebenen Flüssigkeitsstandes im Laugenbehälter nach Ablauf dieser Zeitspanne die Programmsteuereinheit durch den Niveauschalter ein Signal zum Öffnen des Kaltwasserventils erhält. Dadurch wird nun erreicht, daß bei ungenügender Warmwasserzufuhr, weil zum Beispiel der betreffende Wasserdruck zu gering ist, nach Ablauf der festgelegten Zeitspanne das Kaltwasserventil geöffnet und damit die Kaltwasserzufuhr vorgezogen wird. Durch die vorgeschlagene Wasserzulaufsteuerung wird maschinenseitig auch erkannt, wenn überhaupt kein Warmwasseranschluß vorgenommen worden ist. Damit wird die Möglichkeit eröffnet, von Hause aus sämtliche Waschmaschinen mit einem Warm- und Kaltwasseranschluß auszurüsten, da die installierte Maschine mit Hilfe der vorgeschlagenen Steuereinrichtung die Frischwasserzufuhr dann automatisch in sinnvollster Weise vornimmt.This object is achieved according to the invention in that at the beginning of the washing program during a specified period only the hot water valve is open and that if a predetermined one is not reached Liquid level in the tub after this Period of time the program control unit by the Level switch a signal to open the cold water valve receives. It is now achieved that with insufficient Hot water supply because, for example, the one in question Water pressure is too low after the set time Period of time the cold water valve opened and thus the Cold water supply is preferred. By the proposed Water supply control is also recognized on the machine side, if no hot water connection has been made at all is. This opens up the possibility of working from home all washing machines with a warm and Equip cold water connection as the installed Machine using the proposed control device the fresh water supply then automatically in the most sensible way Way.
