Definitions

  • the invention relates to a method for producing a hydrophobic effect of textiles in a household washing machine with means for heating a liquor in a tub and for controlling a washing process and with a Waschstoffvorratshunt for storing a single dose of a liquid washing aid, in which method in the liquor dissolved hydrophobic agents during a washing process similar treatment process are brought into contact with the textiles.
  • Functional textiles such as outerwear, which is worn for protection against moisture from the air, gradually lose their water-repellent property, their impregnation during use. By applying a hydrophobic substance to the textile fibers, this property can be restored.
  • this treatment of textiles is done in a commercial laundry or cleaning company. Increasingly, however, it is also desired to be able to carry out such treatments in a household washing machine.
  • water repellents are offered in the relevant trade, which are suitable for use in household washing machines for impregnating textiles.
  • Such agents consist predominantly of fluorocarbon resins or paraffin-containing agents.
  • the duration of this treatment is determined by the program of washing machine control, which among other things, is determined by reaching the predetermined temperature of the impregnating liquor. At the end of the washing process, the laundry is rinsed several times, so that the amount of impregnating agent applied to the textile fibers of the laundry is reduced again. Therefore, the achievable by the known method hydrophobic effect is relatively low.
  • the invention has for its object to provide a method that is applicable in a household washing machine and in which the achievable hydrophobic effect compared to the prior art is significantly higher.
  • this object is achieved by the features specified in the characterizing part of claim 1 in such a way that the tub with a short on a fleet, d. H. is filled to a ratio of weight of the amount of dry textile to weight of the amount of water before greater than 1: 8, measured amount of water which is heated to at least one of the textiles in the tub to be treated by the textile manufacturer as a treatment temperature (eg 40 ° C) is recommended that a predetermined amount of the hydrophobic agent is rinsed by means of water from the detergent storage chamber into the tub and together with the water forms the liquor, that the textiles first come into contact with the liquor and for a period of up to 30 be treated min and that the lye is removed without rinsing by spinning out of the textiles and from the tub.
  • a treatment temperature eg 40 ° C
  • the totality of the above measures significantly increases the hydrophobic effect on the textiles.
  • the high concentration of the active ingredient in the liquor improves the Aufzieh the active ingredient and prevents over long fleets unnecessarily much drug consumption.
  • the introduction of the active ingredient in the already heated liquor prevents stains on the textiles and improves the Aufzieh of the active ingredient on the fiber again. With a treatment time of less than 30 minutes to achieve good results. Longer dwell times waste energy without added benefit. By dispensing with downstream rinses the risk of dilution or washing off of the active ingredient is avoided by the textile fibers.
  • the tub 1 in Fig. 1 contains a stored therein about a horizontal axis 3 washing drum 2 with carriers 4 for laundry consisting of textiles 7.
  • the driver 4 have scooping devices with which located below in the tub 1 lye 6 scooped during rotation of the laundry drum 2 in the direction of arrow 16 on a Level above the laundry 7 raised and can be rained from the top of the laundry 7. As a result, the wetting and flooding of the laundry 7 is accelerated.
  • an electric motor 14 To rotate the laundry drum 2 is an electric motor 14, which initiates its rotational movement via a belt transmission in the laundry drum 2.
  • a heater 13 which serves to heat the liquor.
  • This liquor 6 passes by operating one of the solenoid valves 8 or 9 in the tub 1 and consists either only of water or a mixture of water and detergent.
  • In the Waschstoffein réelle Spur 11 two chambers 111 and 112 are shown, which are each traversed by the opening of the associated solenoid valve of fresh water.
  • Auxiliary washing agents, which are located in the chambers are then transferred from the water through the line 10 from the Waschstoffein Kunststofftechnisch vibration in the tub 1.
  • Lye 6, which is located at the bottom of the tub 1, can be transported through the drain line 17 and the pump 18 in a manner not shown here to the outside.
  • All switchable or controllable devices such as the solenoid valves 8 and 9, the heater 13, the drum drive motor 14 and the drain pump 18 are switched or controlled by the controller 12 of the washing machine.
  • a temperature sensor 15 For measuring the temperature of the liquor 6 also serves a temperature sensor 15, which passes its measuring signals via the reporting line to an evaluation device 121 in the control device 12.
  • the in Fig. 1 illustrated washing machine for example, operated as it is in Fig. 2 is shown.
  • the solenoid valve 8 is opened to fill water via the - in this example empty - detergent chamber 111 and the line 10 in the tub 1.
  • the amount of water charged in this first phase Ph1 is appropriate to the laundry item 7 stored in the laundry drum 1 minus a quantity which will be later to be supplied together with the hydrophobic drug.
  • This amount first runs in the tub 1 and forms at its bottom a level N V1 , which already touches the laundry drum 1.
  • the scooping devices 5 on the laundry drum are able to absorb water from the tub 1, here also already starting drum rotation, to transport upwards andfastregnen on the laundry 7.
  • the drum rotation is represented by the bold diagram line n. So that the laundry items do not get tangled, the drum 2 is reversibly driven. This mode of operation is indicated here only schematically and can be varied in any way to promote the wetting and the flow of laundry.
  • the solenoid valve 9 opens As a result, incoming water takes from the detergent chamber 112 stored there with hydrophobic drug and now flows as a highly concentrated liquor in the tub 1. There, this liquor mixes with the already existing and heated water, so that the concentration of the liquor to a for the laundry 7 tolerable level decreases, which no longer represents a danger for otherwise possible staining with high concentrations of active ingredient.
  • the drum continues to be driven and combs with its scooping devices 5 vigorously through the now higher (level N V2 ) standing liquor 6. As a result, the laundry, for example, for 20 minutes flooded intensively with hydrophobic brine.
  • the drum movement stops and the operation of the drain pump 18.
  • the free liquor present in the tub 1 is rapidly sucked through the drain line from the pump 18 and removed.
  • the drum drive is then set to spin mode.
  • the high speeds are shown compressed because of space. In any case, three centrifugal pulses are recognizable, each with increasing final speeds, is driven by the more and more bound liquor from the laundry. In the last spin interval, the final spin speed can reach 800 rpm.

Abstract

L'invention concerne un procédé pour produire une action hydrophobe sur des textiles (7) dans une machine à laver ménagère comprenant des ensembles (13, 12) permettant de chauffer une lessive placée dans un récipient pour lessive et pour commander un processus de lavage ainsi qu'une chambre de stockage (112) de produit de lavage permettant de stocker une seule dose d'un produit de lavage liquide. Selon ledit procédé, lorsque les agents actifs hydrophobes libérés dans la lessive (6) pendant un processus de traitement proche d'un processus de nettoyage (Ph2) sont mis en contact avec le textile (7). Ledit procédé peut être effectué dans une machine à laver personnelle. En outre, selon le procédé de l'invention, l'effet hydrophobe escompté est amélioré nettement par rapport à la technique antérieure. Le récipient (1) pour la lessive est rempli d'une quantité d'eau (6) mesurée sur la quantité de lessive, c'est-à-dire un rapport entre le poids de la quantité de textile (7) sec et le poids de la quantité d'eau inférieur à 1 :8, ladite eau étant chauffée à une température d'au moins 40°C, lors de l'humidification du textile (7) dans le récipient (1) pour lessive. De plus, une quantité prédéterminée de l'agent actif hydrophobe est évacuée au moyen de l'eau de la chambre de stockage (112) pour la lessive vers le récipient (1) pour la lessive, cette dernière formant avec l'eau la lessive (6). Le textile (7) entre en contact une première fois avec la lessive (6), puis il est lavé pendant 30 minutes maximum. Lors de la dernière étape (Ph3), la lessive (6) est éliminée du récipient (1) pour lessive sans rinçage par l'essorage des textiles (7).
