Description

The invention relates to a method for washing delicate textiles, in particular wool, in a drum washing machine comprising a lye container, a washing drum and a flooding system.

It is known that a high mechanical stress of the textiles located in the washing drum, which is determined by the rotational movement of the washing drum and the movement of the laundry determined as a result, is associated with a correspondingly high cleaning effect. On the other hand, turning laundry items susceptible to mechanical impact, such as lingerie, bras, suits, blouses, pants, sweaters, curtains, and generally silk or synthetic fabric causes rubbing of the laundry against each other and the drum wall, as well as crushing and flexing the garments unwanted textile damage in the form of wrinkles, roughening, pilling, Blanchissuren, flared edges, warped seams and fabric. To achieve a sufficient cleaning effect, however, a, albeit limited, associated with a stretching, upsetting and walking of the textiles textiles rotary motion of the laundry drum is required by the water in motion and the laundry is held in suspension, so that water, heat and Detergents get well to the textiles and dirt and detergent are removed from the laundry. When washing textiles made of wool occurs depending on the size of the determined by the laundry movement mechanical stress a more or less strong wool shrinkage, that is a shrinkage and felting of the wool, on, even with a small rocking movement of the laundry, the so-called wool swing , is unavoidable.

The invention has for its object to provide a method for washing delicate textiles, especially wool, in a washing machine, which ensures a gentle mechanical treatment of the laundry and beyond a high cleaning effect to avoid damage to the fabric.

According to the invention the object is achieved by a method according to the features of patent claim 1. Advantageous and advantageous developments of the invention are the subject of the dependent claims.

The basic idea of the invention is that the textiles are arranged during the washing process and the rinsing in a quiescent washing drum at a given liquid level partially or completely in the washing or rinsing liquid and only by the achieved during flooding movement of the washing or rinsing liquid and the Textiles, that is, the flow of washing or rinsing fluid through the textiles and a lowering and lifting of the textiles in the washing drum, gently treated mechanically and liquid and detergent introduced into the tissue or dirt and detergent are released from the tissue. Due to the flow of textiles and the slight natural motion of the textiles as a result of lowering and lifting the liquid level, in the washing process to release the dirt on the one hand water and detergent completely penetrate into the tissue and on the other hand, the dirt and detergent in the rinsing process can be completely dissolved out of the tissue , The mechanical proportion of the treatment of the laundry is low, that is a rubbing, stretching, upsetting and Walken the sensitive to such a treatment textiles is avoided, so that with high cleaning effect textile damage and in particular the shrinkage of wool are minimized.

In a further embodiment of the method according to the invention, the textiles are only partially arranged in the washing or rinsing liquid during the washing or rinsing process at low liquid level and large amount of laundry. The washing or rinsing liquid is continuously flooded over a certain period of time, the textiles initially be mechanically treated by lowering in the washing or rinsing liquid and then due to the flow through the sprayed liquid in the washing drum through the textiles. That is, the mechanical action is essentially only due to the flow through the washing or rinsing fluid through the tissue, so that an extremely gentle treatment of sensitive textiles is guaranteed.

In a further embodiment of the invention, the textiles during the washing or rinsing process at elevated liquid level and small amount of laundry are complete or arranged for the most part in the washing or rinsing liquid. The washing or rinsing liquid is flooded in a pulsating manner in a certain period of time, wherein the liquid level and the textiles are alternately lowered and raised in the washing drum and the textiles are gently treated mechanically by their own movement.

In an embodiment of the invention are at the pulsating flooding at least two-thirds of the laundry in the washing or rinsing liquid and the pulsating flooding is performed with respect to the Umflutimpulse and lying between these Um-flood pauses in the same time intervals.

In a further embodiment of the invention, the continuous and the pulsating flooding can also be combined with each other, but the water level height must be adapted to the particular type of flooding.

• Figur 2 ein Verfahren zum Waschen von Wolle in einer Trommelwaschmaschine nach Fig. 1 bei kontinuierlicher Umflutung; und
• Figur 3 ein Verfahren zum Waschen von Wolle in einer Trommelwaschmaschine nach Fig. 1 bei pulsierender Umflutung.

An embodiment of the invention will be described with reference to the drawing, in which

• FIG. 1 a schematic representation of a trained with a circulating system drum washing machine;
• FIG. 2 a method for washing wool in a drum washing machine Fig. 1 with continuous flooding; and
• FIG. 3 a method for washing wool in a drum washing machine Fig. 1 with pulsating flooding.

In the Fig. 1 schematically reproduced drum washing machine comprises a stationary in a housing 1, during the washing and rinsing process up to a certain liquid level with washing or rinsing liquid 2 (alkali or water) filled tub 3 and a washing tub 4 rotatably arranged in the tub 3, in which the textiles to be washed 5 are located. To the underside of the tub 3, a circulating pump 6 and a Umflutleitung 7 are connected. The Umflutleitung 7 opens with a provided at the free end 8 spray head (not shown) in the upper region of the washing drum 4 to spray the pumped out of the tub 3 lye above the textiles 5 again in the washing drum 4 or enter into the textiles 5 ,

The washing of the - in the present embodiment made of wool - textiles 5 takes place at a stationary washing drum 4 and at maximum flooding, that is, once the heater is out of service is flooded. The flooding can be carried out continuously or discontinuously in the heating pauses depending on the laundry.

At the in Fig. 2 shown continuous circulating the liquor is continuously pumped out of the tub 3 during the heating pauses and sprayed back into the washing drum 4. In this case, the liquid level in the washing drum 4 drops once because liquor is withdrawn from the tub 3 for the circulation, and the textiles 5 move in a single movement only once slightly downwards. The further mechanical treatment of the textiles 5 is merely that the lye emerging from the spray head of the circulating line trickles onto the textiles 5 and subsequently generates a natural flow through the textiles. In doing so, detergent and heat are brought to the textiles well and distributed well throughout the washing process. Also in the rinses following the washing process, the rinsing liquid can be continuously flooded. Due to the passing through the textiles 5 flow of rinse water dirt and detergent residues are absorbed by the rinse water, while the textiles remain unmoved and thus spared. The continuous flooding is particularly suitable for washing larger amounts of laundry with little use of water.

Fig. 3 shows yet another process variant for gentle washing of wool (and other sensitive textiles) with pulsating flooding, in which a small amount of fabric is washed at high liquid level. For the sake of simplicity, here too - as in Fig. 2 - Only the liquid level in the washing drum 4 is shown. While the washing process, the liquor 2 is pumped out of the tub 3 pulsating and sprayed back into the washing drum 4, that is, between the individual pumping and spraying cycles is always a preferably the same rest period. The liquid level is adjusted in relation to the loading amount so that the textiles are completely or at least two thirds in the liquor 2. In the rhythm of the pumping and spraying cycles and the intermediate phases of rest, the liquid level rises and falls (arrow A) and at the same time the textiles 5 are raised and lowered (arrow B). In the pulsating flooding with high water levels, the textiles are 5 less, but also flows through from the side, in particular, the slight upward and downward movement of the textiles in the liquor helps to detach the dirt from the textiles and herausloosen from the inside. The rinsing process is performed equally in the alternation of Umflutzyklen and resting phases. By the heightening and lowering of the water level er-witnessed slight intrinsic motion of the textiles, the detergent and dirt residues located deep in the laundry core can also be removed during this rinsing process.

The invention is not limited to the preceding embodiment. Instead of wool, other textiles that are sensitive to mechanical influences can also be washed according to the methods described above. In addition, it is also conceivable to combine the continuous and the pulsating flooding in the washing process and in the rinsing cycles.
