Definitions

  • the invention also relates to a washing machine for carrying out such a method.
  • 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 hydrophobizing substance on the textile fibers, this property can be produced or 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 textiles to be impregnated should be well cleaned beforehand in a separate washing program.
  • the impregnation is then, as is known, carried out separately in a standard washing operation in a so-called long liquor, which is characterized in that a relatively large amount of liquor per kg of laundry is used.
  • a recommended amount of hydrophobizing agent is filled before the start of this standard washing process in the main wash chamber of a detergent dispenser and fed together with cold fresh water to the tub of the washing machine.
  • the impregnating liquor is brought into contact with the laundry while being heated in the tub by means of a heater.
  • the duration of this treatment is determined by the program of washing machine control, the u. a. also determined by reaching the predetermined temperature of the impregnating liquor.
  • 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 process of producing or restoring the impregnation is consistently performed separately from any other treatment operation in the washing machine, so that the user of the washing machine has to perform the loading and setting operations twice and also has to wait the full length of both separate treatment programs.
  • the invention has for its object to provide a method that is applicable in a household washing machine and in which the user of the washing machine finds a treatment process with which the textiles can be both cleaned as well as impregnated in a continuous processing program. Furthermore should be significantly improved with a continuous processing program, the achievable hydrophobic effect compared to the prior art.
  • this object is achieved by the features specified in the characterizing part of claim 1 in such a way that a washing process for cleaning the textiles with the addition of a special detergent, which is suitable in addition to its known soil-removing effect also for detachment of any existing detergent ingredients from the textiles , Carried out in a flowing amount of fresh water and at the end of the used liquor is pumped, that after the washing process with replacement of the respective lye filling of the predecessor process a multi-stage rinsing process for the textiles is carried out and that after the end of the rinsing process with replacement of the last rinse liquor and adding the hydrophobic Substance is carried out in a newly added amount of fresh water, a treatment process for impregnating the laundry.
  • 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 maximum treatment time of 20 minutes, good results are achieved. Longer residence times waste energy without additional benefit. By dispensing with downstream rinses the risk of dilution or washing off of the active ingredient is avoided by the textile fibers.
  • the invention also provides a washing machine for carrying out the method according to the invention or one of its developments.
  • input means are provided by which a program sequence for the washing machine can be preselected, in which the method runs automatically, and a control device is provided by which the sequence of the preselected program is automatically controlled, as soon as there is a start signal
  • the tub 1 in Fig. 1 contains a stored therein about a horizontal axis 3 washing drum 2 with carriers 4 for existing laundry textiles 7.
  • the driver 4 have scooping devices 5, with which located below in the tub 1 lye 6 during rotation of the laundry drum 2 in the direction of arrow 16 from a level N v , which is above the lowest point of the laundry drum 2, scooped up, raised to a level above the laundry 7 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 is arranged, which serves to heat the liquor.
  • This liquor 6 passes through actuation of one of Solenoid valves 8 or 9 in the tub 1 and consists either only of water or a mixture of water and detergent.
  • Solenoid valves 8 or 9 in the tub 1 and consists either only of water or a mixture of water and detergent.
  • In the Waschstoffeinargues affection 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
  • 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 FIGS. 2 and 3 is shown.
  • the scale on the ordinate applies only to the speed of the laundry drum 2; no scale is assigned to the other parameters.
  • the solenoid valve 8 is opened in order to charge water via the detergent chamber 111 filled with laundry detergent to be impregnated in this example for the preparatory cleaning and the line 10 into the tub 1.
  • the water carries this special agent into the tub 1, where it is distributed.
  • the washing process 2 which consists of the three phases PhB for wetting the laundry, PhW for washing the laundry and PhSp for rinsing the laundry, the laundry drum 2 is driven according to the bold solid line diagram n only at a lower speed (eg 23 rpm) than it is after wetting the case.
  • the drum 2 is driven only in the direction of arrow 16, in which the scooping devices 5 unfold their full effect on the drum casing.
  • the laundry drum 2 is continuously reversibly driven with, for example, 50 rpm, so that the laundry intensively with the during the Wetting phase already heated wash liquor comes into contact.
  • the wash liquor is pumped off and replaced with a fresh water lye filling.
  • the inflowing water can be passed, for example, through the already emptied detergent chamber 111.
  • the rinsing phase PhSp contains several stages with constantly new fresh water fillings, so that the washing lye is extremely diluted. It should namely remain as possible no residue of special detergent in the laundry. The number of rinsing stages is therefore set to this requirement.
  • the amount of water filled in the first phase Phl1 is appropriate for the laundry lot 7 stored in the laundry drum 2 minus an amount remaining in the laundry from the rinsing process and another amount needed for later supplying the hydrophobizing agent. This amount of water again passes through the solenoid valve 8 through the already emptied detergent chamber 111 into the tub, where it is first heated.
  • the Impregnating lye well mixed and evenly Laundry items 7 distributed.
  • the drum continues to be driven and meshes with its scooping devices 5 vigorously through the impregnating lye 6.
  • the laundry is intensively flooded, for example, for a maximum of 20 minutes by hydrophobicizing liquor.
  • Improved hydrophobizing agents also allow for a shorter exposure time of less than 20 minutes.
