A washing soln. discharge system with an emptying pump connected in series is also provided. The mass equalisation device takes the form of liq. receptacle (8) which is connected to the washing soln. container (1). The receptacle (8) is connected to the fresh water supply (12) and can be filled with fresh water before the start of the spinning process. ADVANTAGE - The mass equalisation process is carried out in a way that cuts material consumption. The machine is lighter and easier to dispose of.

Description

Die Erfindung betrifft eine programmgesteuerte Trommelwasch- und Schleudermaschine nach dem Oberbegriff des Schutzanspruchs 1.The invention relates to a program-controlled Drum washing and spinning machine according to the generic term of protection claim 1.

Eine Trommelwasch- und Schleudermaschine dieser Art ist aus der DE 26 33 603 C2 bzw. DE 27 19 452 C2 bekannt. Bei solchen Trommelwasch- und Schleudermaschinen sind zur besseren Gewichtsverteilung an der Außenseite des Laugenbehälters des schwingbeweglich mit dem Maschinengehäuse verbundenen Waschaggregats gegossene Ausgleichsgewichte (Ballastgewichte) angebracht. Als Material dafür wird heute in der Regel Beton verwendet. Da diese Ausgleichsgewichte fester Bestandteil der betreffenden Maschine sind, tragen sie wesentlich zu deren Gesamtgewicht bei. Als Folge davon wird dann eine entsprechend ausgelegte und damit teure Transportverpackung erforderlich. Desweiteren bereitet das Aussondern solcher Ausgleichsgewichte und deren Entsorgung bei der Verschrottung solcher Waschmaschinen ebenfalls gewisse Probleme.A drum washing and spinning machine of this type is out known from DE 26 33 603 C2 and DE 27 19 452 C2. At such drum washing and spinning machines are for better weight distribution on the outside of the Suds container of the oscillating with the Machine housing connected cast unit cast Balance weights (ballast weights) attached. When The material used for this is usually concrete. There these balance weights an integral part of the concerned machine, they contribute significantly to their Total weight at. As a result, one becomes appropriately designed and therefore expensive transport packaging required. Furthermore, the preparation of such Balance weights and their disposal at Scrapping such washing machines also certain Problems.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, den Massenausgleich bei Trommelwasch- und Schleudermaschinen mit einem schwingend aufgehängten Waschaggregat während der Schleuderphase auf materialsparende Weise durchzuführen. Dabei soll neben einer Reduzierung des Maschinengesamtgewichtes auch das Entsorgen solcher Maschinen erleichtert werden.The invention is based on this prior art based on the task of mass balancing drum washing and centrifugal machines with a swinging suspension  Washing unit during the spin cycle perform material-saving manner. In addition to a reduction in the total weight of the machine Disposal of such machines will be made easier.

Die Lösung dieser Aufgabe gemäß der Erfindung ist dem kennzeichnenden Teil des Schutzanspruchs 1 zu entnehmen.This object is achieved according to the invention characteristic part of the protection claim 1.

Vorteilhafte weitere Ausgestaltungen des Gegenstandes der Erfindung sind in den Unteransprüchen angegeben.Advantageous further refinements of the subject of Invention are specified in the subclaims.

Die Trommelwasch- und Schleudermaschine nach der Erfindung zeichnet sich durch eine recyclingfreundliche Konstruktion aus. Durch den Wegfall des eine verhältnismäßig große Masse aufweisenden Betonausgleichgewichtes wird auch der Wärmeentzug aus dem Laugenbehälter reduziert und damit eine weitere Einsparung an Primärenergie in der Heizphase während dem Waschen erreicht.The drum washing and spinning machine according to the invention is characterized by a recycling-friendly construction out. By eliminating a relatively large mass having a concrete balance weight is also the Heat extraction from the tub is reduced and therefore one further savings in primary energy in the heating phase reached during washing.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird anhand dieser nachfolgend näher beschrieben.An embodiment of the invention is in the drawing is shown and will be described in more detail below described.

Die Zeichnung zeigt den schematischen Aufbau einer Trommelwasch- und Schleudermaschine mit einer Massenausgleichseinrichtung.The drawing shows the schematic structure of a Drum washing and spinning machine with one Mass balancing device.

Die in der Zeichnung dargestellte Trommelwasch- und Schleudermaschine hat einen Laugenbehälter 1, in dem eine perforierte Waschtrommel 2 umlaufend untergebracht ist. Der Laugenbehälter 1 steht mit einer Waschmitteleinspülwanne 3 (Einspülkammer) über eine Zwischenleitung 3′ in Verbindung. Vom Bodenbereich des Laugenbehälters 1 geht ein Laugenablauf 4 mit einer Entleerungspumpe 5 und ein der Pumpe nachgeschaltetes Ablaufrohr 6 ab. Ferner ist an der tiefsten Stelle des Laugenbehälters 1 ein Wasserstandregler 7 (Druckwächter) angeschlossen. Mit dem Laugenbehälter ist ein für den Massenausgleich dienender Flüssigkeitsaufnahmebehälter 8 fest verbunden, der eine in den Laugenbehälter 1 mündende Entleerungsleitung 9 aufweist. Das Flüssigkeitsvolumen des Behälters 8 liegt bei etwa zehn Liter. In der Entleerungsleitung 9 ist ein steuerbares Entleerungsventil 10 angeordnet. Der Flüssigkeitsaufnahmebehälter 8 ist über einen Frischwasserzulauf 11 mit Magnetventil 11′ an der Frischwasserzuführung 12 angeschlossen. Vom Flüssigkeitsaufnahmebehälter 8 geht eine in das Laugenablaufsystem mündende Entlüftungsleitung 14 mit einer Abschalteinrichtung 19 gegen Überfüllung ab. Die Waschmitteleinspülwanne 3 hat eine übliche Entlüftung 15 sowie für deren einzelne Waschmittelkammern von Magnetventilen 16, 17, 18 beherrschte Frischwasserzuläufe 19, 20, 21.The drum washing and spinning machine shown in the drawing has a tub 1 , in which a perforated washing drum 2 is housed all around. The tub 1 is connected to a detergent dispensing trough 3 (dispensing chamber) via an intermediate line 3 '. From the base area of the tub 1 , a tub drain 4 with an emptying pump 5 and a drain pipe 6 connected downstream of the pump depart. Furthermore, a water level controller 7 (pressure switch) is connected to the lowest point of the tub 1 . A liquid receptacle 8 serving for mass balance is fixedly connected to the suds container and has an emptying line 9 opening into the suds container 1 . The liquid volume of the container 8 is about ten liters. A controllable drain valve 10 is arranged in the drain line 9 . The liquid holding container 8 is connected via a fresh water inlet 11 with a solenoid valve 11 'to the fresh water supply 12 . From the liquid receptacle 8 , a vent line 14 opens into the lye drain system with a shutdown device 19 to prevent overfilling. The detergent dispenser trough 3 has a customary vent 15 and fresh water inlets 19 , 20 , 21 controlled by solenoid valves 16 , 17 , 18 for its individual detergent chambers.

Der als Massenausgleichgewicht dienende Flüssigkeitsaufnahmebehälter 8 soll zweckmäßig in einer solchen Lage im Maschinengehäuse angeordnet sein, daß er im gefüllten Zustand schwerpunktsneutral ist. Die Programmsteuerung der Maschine ist so auszulegen, daß der Flüssigkeitsaufnahmebehälter 8 jeweils kurz vor Start der Schleuderphase durch entsprechende Steuerung des Ventils 11′ mit Frischwasser gefüllt wird. Bei Start des Waschprogramms kann das im Flüssigkeitsaufnahmebehälter 8 befindliche Wasser beim Vor- oder Hauptwaschvorgang mitverwendet werden.The serving as a mass balance weight liquid receptacle 8 should be suitably arranged in such a position in the machine housing that it is neutral in the center of gravity when filled. The program control of the machine is to be designed so that the liquid holding container 8 is filled with fresh water shortly before the start of the spinning phase by appropriate control of the valve 11 '. At the start of the washing program, the water in the liquid holding container 8 can be used in the pre-washing or main washing process.
