Definitions

  • the invention relates to a method for removing stains from textile goods, in which an area of the textile goods soiled by a stain is cleaned with the aid of a cleaning liquid, the textile goods are clamped in the area to be cleaned between two washing elements each provided with at least one opening, and the washing elements can be pressed against one another in a sealing manner while the textile goods are clamped.
  • the invention relates to a device for removing stains from textile goods with which a stain that stains the textile goods in one area can be removed with the aid of a cleaning liquid, the textile goods being clampable in the area to be cleaned between two washing elements each provided with at least one opening, and the Rinsing elements by clamping the textile would be sealingly pressed together by a holding means.
  • the invention relates to a cleaning device, in particular a household washing machine, with an internal pump and an internal cleaning housing, which cleans textile goods with a cleaning liquid and has an inlet and an outlet.
  • the device also requires a higher contact pressure of the rinsing elements, which can cause pressure margins on the textile goods and damage them.
  • Another disadvantage of the known device for removing stains is that the cleaning liquid in the case of dense textile goods only partially passes through them, so that residues of the cleaning liquid remain on the textile goods and / or the pressure of the cleaning liquid must be increased.
  • Another disadvantage of the known device is that it is not possible to rinse out detergent residues from the textile goods without having to replace the cleaning liquid with greater circumstances.
  • the invention has for its object to easily and quickly clean textile goods effectively with a low need for cleaning liquid, without the risk that residues of dirt or detergent or dirt, detergent or pressure marks remain on the textile goods.
  • This object is achieved in that the cleaning liquid is sucked into the textile goods by a vacuum generated by a pump and is sucked off again from the textile goods.
  • the suction of the cleaning liquid from the textile goods is known from German Offenlegungsschrift No. 2.832.625.
  • the cleaning liquid is applied to the textile goods with a comparatively high jet speed in order to remove the stain.
  • a separate and specially adjustable pump is required for this.
  • the problem of spraying and the spreading of the cleaning liquid on the textile goods, which occurs when the cleaning liquid is illuminated at high speed, is solved by a shield.
  • a disadvantage of the method is that a pump for suction and a pump for flowing the cleaning liquid. speed is required.
  • Another disadvantage is that a relatively high suction power has to be applied to extract the liquid from the textile goods, since the textile goods are only placed on a rinsing element and air is sucked in in addition to the cleaning liquid.
  • cleaning liquid is understood to mean any liquid which is suitable for cleaning textile goods, in particular water with or without the addition of washing powder.
  • the negative pressure generated by the pump is in each case related to the ambient pressure in which the process is carried out.
  • the cleaning liquid sucked into the textile goods is conveyed due to a pressure drop, the pressure in the area of the clamped textile would be lower than the ambient pressure.
  • An advantage of the method according to the invention is that the cleaning liquid does not emerge from the clamped area due to the suction effect of the pump and requires a low contact pressure of the flushing elements. This prevents the formation of dirt, detergent or pressure marks on the textile goods. It is also advantageous that only a comparatively low vacuum has to be generated in order to suck the cleaning liquid through the textile goods, since no air reducing the vacuum can flow in by the sealing elements being pressed together.
  • the cleaning liquid is sucked in and sucked out on at least one side of the clamped textile goods by the rinsing element located on this side.
  • the cleaning liquid sucked into the textile goods partly flows past it and partly passes through it.
  • the part of the cleaning liquid that has not passed through the textile goods is sucked off again directly by the rinsing element.
  • the cleaning liquid When the cleaning liquid is sucked in and out on one side of the textile product, the cleaning liquid can also be drawn in with a denser textile product with a comparatively low negative pressure. In addition, this enables the use of a comparatively small pump with low suction power. In addition, it is also advantageous that coarse dirt particles do not have to pass through the textile goods, but rather can be removed directly by the cleaning liquid after loosening.
  • the pressure of the sucked-in cleaning liquid is reduced via a throttle.
  • the underpressure occurring in the field of textile goods can be increased.
  • the object is also achieved by a device for removing stains from textile goods, by means of which a stain soiling the textile goods in an area can be removed with the aid of a cleaning liquid, the textile goods being clamped in the area to be cleaned between two washing elements each provided with at least one opening and the rinsing elements can be sealingly pressed together by a holding means while the textile goods are clamped in, the cleaning liquid being able to be sucked into the textile goods by means of a vacuum generated by a pump and being sucked off again from the textile goods.
  • An advantage of such a device in addition to the advantages already mentioned, is that only one pump is required to transport the cleaning liquid.
  • the cleaning liquid sucked in via the first opening is sucked out through a second opening. It is advantageous that the vacuum required for sucking the cleaning liquid through the textile goods does not have to be applied. If the textile product is clamped between two such rinsing elements, the cleaning liquid can flow past on each side of the textile product and partially flow through the textile product.
  • a flushing element is expediently releasably connectable to a shaft of the holding means via an eyelet provided on the latter. With such a releasable connection, the flushing element provided with the eyelet can be moved along the shaft and pivoted about its axis. Such a connection to the holding means makes it easier to clamp the textile goods to be cleaned.
  • the rinsing element can be designed in such a way that the cleaning liquid is supplied and removed via the interior of the rinsing element itself.
  • the flushing element provided with the eyelet can be pressed against the other flushing element via a fastening element arranged on the shaft of the holding means.
  • a fastening element can consist, for example, in a nut which can be adjusted in height along a thread on the shaft. The advantage of this is that the contact pressure of the rinsing elements and the distance between the rinsing elements can be adjusted according to the thickness of the textile goods by the fastening element.
  • At least one flushing element can be tiltably connected to the holding means.
  • a tiltable flushing element can change its angular position when the flushing elements are pressed together, so that any unevenness that may occur can be compensated for and thus the flushing elements close tightly. Due to the tiltable mounting of the flushing element, any tolerances in the manufacture of the flushing elements can also be if balanced.
  • At least one flushing element preferably has a compensator which can be compressed like an accordion when the flushing elements are pressed together.
  • a compensator which can be arranged in the manner of a bellows in the region of the opening of the flushing element, presses or contracts under the contact pressure of the flushing elements, so that a flush closure with the textile product is ensured. Damage to the textile goods by clamping them between the rinsing elements is also avoided by the elastic yielding of the compensator.

Abstract

L'invention concerne un procédé et un dispositif pour éliminer les taches de produits textiles. Lorsque l'on élimine localement des taches de produits textiles (10), une partie du liquide nettoyant forme souvent des auréoles causées par la propagation de l'humidité dans le produit textile (10). Le coût de dispositifs pour éliminer des taches est en outre considérable, étant donné qu'ils utilisent plusieurs pompes de haute puissance. Afin d'éviter ces inconvénients, le liquide nettoyant est aspiré dans le produit textile (10) par la pression négative générée par une pompe, puis aspiré à nouveau du produit textile par la même pression négative. Le liquide est aspiré à travers le produit textile par l'effet de succion et la formation d'auréoles est évitée à peu de frais.
