Definitions

  • the invention relates to a method for washing laundry according to the preamble of patent claim 1.
  • the invention is based on the object of further improving the method for washing laundry in program-controlled washing machines of the type in question so that the wash-active substances of the individual detergent components are also fully effective in each washing phase of a washing process can be used and thus fully used.
  • the detergent components are supplied independently of one another at their optimum operating temperature to the tub and thus the laundry and that at the appropriate temperatures there is also a sufficient period of action on the laundry.
  • a complete washing process usually consists of a pre-washing or soaking phase I with a lower temperature, a washing phase II (main wash) with a higher temperature and a cooling, rinsing and spinning phase III that concludes the washing phase II.
  • the temperature of the wash liquor rises from cold to almost 50 ° C., time 1. It is advisable to limit this temperature to approximately 30 to 40 ° C.
  • those detergent components are added to the wash liquor that already achieve their optimum effect at low temperature.
  • Such detergent components are e.g. B. water softeners and enzyme-containing soaking agents.
  • This low temperature is maintained for a certain period of time. During this period, e.g. B. protein soiling washed out of the laundry. From time 3, the washing liquor is heated to the maximum or washing temperature which is reached at time 4 and is also maintained until the end of time 5.
  • the prewash or soaking phase I is now advantageously divided into a time period A with high mechanics and a time period B with less mechanics.
  • Mechanics mean the mechanical processing of the laundry in the wash liquor by moving the laundry drum in an alternating direction of rotation.
  • the time period A begins when the prewash temperature is reached at Time 1 and ends at time 2, at which time period B then begins, which ends at time 3 when heating to the maximum or washing temperature begins.
  • the method for washing laundry in a program-controlled washing machine with a rotating drum in a tub and a device for automatically metering and supplying preferably pumpable detergent components is now advantageously carried out in such a way that the laundry in the prewash or soaking phase I is exposed to a high level of mechanics during time period A and only a low level of washing mechanics during time period B.
  • the time period B with the low washing mechanism is of longer duration compared to the time period A with the higher washing mechanism. About 5 to 15 minutes are provided as the time period for the time period A with the high washing mechanism.
  • the time period for time period B with the lower washing mechanism is substantially greater than the time period for time period A with the high washing mechanism.
  • the duration can be one to several hours.
  • the high level of washing mechanics in this process step is characterized in that the washing drum moves more than 50% ( ⁇ 50%) of the time in the alternating direction of rotation during the time period A and is kept at a standstill for the remaining time.
  • time period B for the lower washing mechanism on the other hand, the period of movement of the laundry drum is less than 50% ( ⁇ 50%), preferably 1 to 10%.
  • the time period B with the lower washing mechanism can advantageously be selected and thus set by the user in addition to the usual washing program setting.
  • the heating-up time period C now begins to reach a preselected or program-specific wash liquor temperature, which is maintained until time 5. From time period C, washing is continued with a washing mechanism that corresponds to the selected basic program.
  • the detergent components (Bleach and / or detergent substances, so-called surfactants) for wash phase II are added to the wash liquor, which can then develop their full effectiveness in the post-wash period D or which increase the effectiveness of the wash components (e.g. enzymes) supplied for sections A and B could have belittled.
