Definitions

  • the invention relates to a method for operating a washing machine, in particular a drum washing machine according to the preamble of claim 1, a washing machine operating according to this method being suitable for use in the household as well as for commercial purposes and being used in certain construction modifications can.
  • drum washing machines with a washing and centrifugal drum are known based on the patent literature, company documents and a wide range of brochure material as well as consumer goods already on the market.
  • the washing, rinsing and spinning process takes place only in one washing and spinning drum, whereby about 4.5 kg of dry laundry can be processed in a washing cycle with a relatively low consumption of water, energy and detergent as well as an acceptable cleaning effect.
  • drum washing machines without a tub are also known, in which the washing and / or rinsing liquors are pumped into a recycling tank and from there can be used again for a next batch of laundry.
  • DD-PS 259 316, DD-PS 301 607 For these machines, however, a complex and complicated heating, control and fleet management system is required, so that such devices have not yet been implemented on the market.
  • the object of the invention is therefore to provide a method for operating a washing machine, in particular a drum washing machine, according to the preamble of claim 1, with which the effective consumption values per unit of laundry are further minimized without deteriorating the washing result with regard to the cleaning and rinsing effect can.
  • the advantages that are achieved by the invention are that compared to the known technical solutions in the field of drum washing machines with a relatively low mechanical engineering overhead, the consumption of drinking water, detergent, electrical energy for heating the washing liquor and the time required per kilogram of laundry are essential is reduced.
  • FIG. 1 shows a basic illustration of the basic fleet management system (here using the example of a washing machine with two top loading systems).
  • both systems can be designed both independently and as a function of one another.
  • the programming of the individual processes or control of the individual assemblies is designed in the same way as for a single drum washing machine.
  • the main use value of the two-drum washing process according to the invention the simultaneous washing of different items to be washed or a batch of laundry items with a larger filling mass can be easily realized.
  • the drum of the primary system is loaded with a lot of approx. 2 kg of delicates (e.g. curtains or similar laundry) and the program "Delicates" with a washing temperature of 40 degrees C is entered using the program selector.
  • the drum of the secondary system is loaded with approximately 3.5 kg of colored laundry. Due to the relatively high degree of soiling, the program "Colored laundry with pre-wash” and a temperature of 40 degrees C are selected. After the connections to the fresh water and sewage system and the electrical network have been properly established and checked, detergents and laundry care products have been added to the containers provided on the machine and the drum and housing covers have been closed Start of the program.
  • a start pulse is sufficient to start the primary system first and that the program sequence in the secondary system starts automatically after a specified time unit or certain parameters, such as fleet level in the secondary system or completion of the washing and pumping process in the primary system becomes.
  • the control system can also be designed so that the program sequence can be started separately in the secondary system.
  • the exemplary embodiment is constructed in such a way that, after the washing and heating process has ended, the liquor present in the primary system is pumped out into the secondary system, with the involvement of a spinning step (this can also be hidden under certain circumstances).
  • the "Prewash" program step is carried out with the wash liquor from the primary system that has already been used. After the pre-wash cycle, the washing liquor, now exhausted in its washing power, is pumped out into the sewage system. After completion of the program of the rinse cycle 1 in the primary system, in which the items to be washed may still have a certain amount of heat from the wash cycle in the wash liquor has entered, this first rinse liquor, which also contains a relatively high proportion of detergent-active substances, is pumped out into the secondary system with the involvement of a spinning step (this may also be hidden under certain circumstances). The second rinse cycle now takes place in the primary system under the inflow of fresh water.
  • the main wash cycle with the wash liquor from the 1st wash cycle is completed from the primary system, if necessary with a certain amount of fresh water as compensation to the specified fleet level.
  • the used washing liquor is then pumped into the sewage system with the involvement of a spinning step.
  • the rinse liquor of the primary 2nd rinse cycle is pumped into the secondary system - also by switching on a skidable skidding step - and is used there as a rinse liquor for carrying out the 1st rinse cycle, if necessary with topping up a certain amount of fresh water to the specified liquor level.
  • the 3rd rinse cycle in the primary system or the 2nd rinse cycle in the secondary system takes place in the same way, i.e. the 3rd rinse cycle in the primary system with fresh water and the 2nd rinse cycle in the secondary system with the wash liquor of the 3rd rinse cycle from the primary system carried out. After completing the 3rd rinse on the primary side there the final spin as specified in the program.
  • the 3rd rinse cycle in the secondary system is carried out with fresh water supply and also ends here with the final spin specified in the program.
  • colored laundry with a temperature of 90 degrees C is to be washed in the primary system and colored laundry with a temperature of 60 degrees C in the secondary system.
  • a liquor temperature reduction from the temperature reached of close to 90 degrees C to the temperature of 60 degrees C set for the secondary system must be carried out here. This is done with the supply of fresh water. This naturally eliminates the need to heat the wash liquor in the secondary system.
  • the rinse cycles are carried out in a manner analogous to that previously described, ie the rinse cycles in the primary system are each carried out with fresh water and the rinse cycles 1 and 2 in the secondary system are each carried out with the washing liquors from the rinse cycles 1 and 2 of the primary system.
  • the 3rd rinse in the secondary system is carried out with fresh water.
  • the speed regime during the rinse cycles, ie switching on spinning steps in the reversing or. Drain phases, is designed analogously to the previously described embodiment.
