Definitions

  • the invention relates to a drum washing machine according to the Preamble of claim 1 and a method for operating a drum washing machine during the washing operation.
  • EP 0 644 290 A1 discloses a washing machine, in which a part of the rinse water in the Drum is sprayed or injected and only after the rest of the first moisturization achieved Fresh water quantity supplied by means of a flushing device becomes.
  • GB 2 276 394 discloses a washing machine in the for the rinsing process depending on the amount of laundry or their Soiling and / or the nature of the laundry one is selected from two different rinse modes. Doing so with a small amount of laundry or with less heavily soiled Wash selected a rinse mode in which rinsing with simultaneous removal of water by spinning and thereby compared to a flushing operation with free Brisk the amount of rinse water is reduced.
  • GB 2 219 603 describes a washing process for a washing machine known, in which first a laundry ring by adjusting a spin speed generated on the laundry drum and then the inside of this laundry ring sprayed with rinsing liquid using a spray device becomes. The applied rinsing liquid is washed through hurled through the laundry ring, taking detergent and dirt residues from the laundry ring. The through flung and with detergent and dirt residues Enriched rinsing liquid is pumped out continuously.
  • the invention is based on the problem of a drum washing machine and a method of operating a drum washing machine to indicate during a flushing operation through which a particularly low water consumption good rinsing effect is set at the same time.
  • the drum washing machine according to the invention thus realizes with particular advantage the possibility of a selective Rinsing. It has turned out to be for saving water while ensuring a good rinsing effect proven to be advantageous when depending on the Loaded laundry quantity or the laundry type and the numerical Number of pending rinse the selection of Washing program takes place, this then the corresponding Parameters regarding the water to be flushed in and for example the flushing time is adjusted accordingly. Because for example, with a large amount of laundry are slightly larger Amounts of fresh water required, but for example the laundry is already wetted after the second rinse cycle is so that no further water can be introduced for this and is consequently the one corresponding to this rinse cycle Water consumption can be reduced. This is with the invention Drum washing machine a highly selective, because rinsing is adapted to the actual conditions.
  • At least a first washing program is designed such that part of the fresh water to be introduced by means of the spray device directly on the at high speed rotating laundry stuck to the drum wall will, and that after introducing part of the Fresh water the remaining fresh water after reduction the speed to a low washing speed via the induction unit introduced to form a free fleet becomes.
  • This program which is conveniently in the first Rinse cycle is used in particular to avoid of enrichment problems that only occur with a rinse without free fleet are given, an advantage. It is also advantageous this enables rapid humidification, since due to the rotation of the drum on the inside of the water quickly forming to the outside with any contaminants becomes. It is also advantageous that due to the formation of a free liquor also washed in a fabric softener or the like can be.
  • At least one wash program is a wash with free Brisk and at least one additional wash program without a free fleet. Because, for example, in the frame the first rinse it is advisable to use more water, So it is rinsed with a free liquor, because with this Rinse cycle the highest detergent concentration to be rinsed out is present. The subsequent rinses can then with a washing program without a free liquor, whereby for example, the last rinse is again in view be carried out on a rinse aid with free liquor can.
  • At least a second washing program is designed in this way is that at least part of the fresh water to be introduced by means of the spray device directly onto the low washing speed rotating laundry is introduced, so that this realizes a process without a free fleet is.
  • the actual circumstances adapted selection of the specific rinse cycle to be used Rinsing program also takes into account the actual circumstances Being able to supply fresh water can in within the scope of the invention it is further provided that the amount of fresh water to be supplied depending on the amount of laundry and / or type, at least at the beginning of the flushing operation, is preferably predeterminable for each wash cycle, so as little water as possible while ensuring sufficient Use flushing.
  • a division of the fresh water to be introduced is provided such that a first part by means of the injection device, and the rest by means of the injection device can be introduced can according to the invention further be provided that at least in the context of the first Washing program the amount of by means of the spray device introducible fresh water can be predetermined.
  • the invention further a method for operating a drum washing machine during the flushing operation, which consists of at least there are two separate rinses, the drum washing machine a program control that controls the flushing operation, one rotatably arranged in a tub Laundry drum, at least one washing device for, if necessary a treatment agent carrying fresh water in the drum area, at least one injection device for Spraying fresh water into the inside of the drum, and a the fresh water supply may depend on the water level controlling agent.
  • the method according to the invention is characterized in that that as part of the first rinse with the laundry drum rotates at a speed corresponding to a spin operation, after which a predetermined Part of the fresh water sprayed into the inside of the drum, then the speed is reduced to a washing speed and the remaining fresh water via the injection device or the flushing device to form a free liquor is added, and that the subsequent rinse either done in the same way, or via the injection device a predetermined amount of water without forming a free one Brisk is introduced, with free after each rinse Water is pumped out.
  • the method according to the invention is therefore advantageous as part of the first wash cycle regardless of the type the load always a rinse with free liquor, whereby those already mentioned, resulting from spin wetting Allow advantages. Only with the following Rinse cycles have the option of one Rinsing with or without a free fleet, this being the case with these Rinsing processes used (free fleet - without free fleet) according to the invention depending on the loaded Amount and / or type of laundry and / or the numerical number the wash cycle is selected.
  • the remaining water as part of the rinsing free liquor less than 5 minutes, preferably less be more than 4 minutes.
  • the exposure time after the end of Introducing fresh water in the rinse cycle without free The liquor can, according to the invention, be about 2 minutes, preferably about 1 minute.
  • the program-controlled drum washing machine shows one Tub 1 in which a reversible; shell side perforated laundry drum 2 rotatable by means of a motor 3 is arranged via drive means 4 known per se.
  • the lower area of the tub 1 collects from the Drum interior draining or in this area introduced water, which can be pumped out via a drain pump 5 is.
  • the washing drum 2 is on the front Load opening 6 can be filled with laundry.
  • Above the Suds container 1 is a front pull-up Detergent drawer 7 and an associated detergent dispenser 8 arranged. This communicates with one Supply line 9 for fresh water.
  • This feed line 9 divides into a detergent rinsing line 10 and a line 11, which in the form of an injection device 12 inside the Drum ends.
  • the lines 10, 11 are not over shown, known solenoid valve means controllable.
  • a second one Connect the rinse cycle which is the same. alternative this can also be done with a rinse cycle without a free fleet be used.
  • the drum 2 rotates only with normal washing speed. A defined amount of water is introduced by means of the spray device, so that the Laundry is rinsed with this. After a predetermined exposure time of, for example, one minute the free, is in the tub on the bottom pumped up water, after which the rinse cycle ends is.
  • the rinsing procedure used in the next rinse can on the one hand on the amount or type of laundry brought in, on the other hand, the numerical number of rinses be dependent.
