Definitions

  • the present invention relates to a method and a device for washing, using a washing machine with a rotary drum, objects such as pieces of woven or nonwoven fabric and, in particular, clothing.
  • the invention aims to provide another solution to this problem. It starts from the observation that prior to modern washing techniques, the weak detergent power of the detergents was compensated for by exerting a mechanical action on the laundry, in particular threshing of the laundry.
  • the invention therefore proposes, with a view to reducing the amounts of detergent necessary for carrying out the detergents, to generate inside the washing machines, a mechanical threshing action similar to that obtained in the dry cleaning machine described in US Patent 1,760,218 which is designed to receive, inside a rotating drum, wooden balls.
  • the Applicant has also developed a method consisting in introducing into the drum of the machine bodies (for example having a shape analogous to that of golf balls) made of a relatively hard elastomer.
  • the weight of the objects to be introduced into the drum is at least equal to the weight of the objects to process and is preferably between once and three times this weight.
  • this method has the drawback of limiting the quantity of objects to be treated, due to the large weight and the volume of the bodies used to cause wear.
  • the invention therefore more particularly aims to solve the problems mentioned above. To this end, it therefore proposes a method for the treatment of objects such as pieces of fabric or the like, using a rotary drum washing machine containing water, this method consisting in introducing into the drum massive elements of rounded shape with the objects to be treated, then to rotate the drum thus loaded.
  • this method is characterized in that the solid elements have a lenticular shape with two opposite concave faces and are made of an elastomer having good wear resistance, a density between 1000 and 1600 kg / m3 and a shore hardness between 50 and 80, preferably greater than 70.
  • a predetermined quantity of powder or abrasive liquid or even pumice stone may be added inside the drum.
  • This solution has the advantage of increasing the quantities of objects to be treated in the same treatment cycle, of shortening this cycle and of better controlling the phenomenon of wear, in particular by adjusting the quantity of liquid or abrasive powder and / or the grain size of the pumice stone.
  • the machine drum can advantageously be provided with blades parallel to the axis of rotation of this drum and extending radially projecting from its internal cylindrical surface.
  • the solid element 1 has a substantially lenticular shape with opposite concave faces: its peripheral edge 2 is substantially toric, while its central region 3 forms two opposite concavities 4, 5.
  • this element 1 is approximately 5 cm, while its weight is approximately 30 g.
  • This element 1 is made of an elastomer having a density between 1 and 1.6, and a shore hardness greater than 70.
  • a determined quantity of these elements is placed inside the drum 6 of the machine, this quantity being a function of the nature of the laundry and its state of dirtiness.
  • Washing is carried out in the usual way by adding a detergent product to the washing water (in an amount much lower than the usual doses).
  • vanes 7 in the drum 6 of the machine facilitates the ascent of the solid elements and allows them to strike the laundry from above, improving the threshing effect thus produced.
  • a predetermined quantity of additional bodies and, optionally of powder, and / or liquid, or of pumice stone in addition or instead of detergent or bleach.
  • the treatment cycle is substantially the same as that previously mentioned. However, in this case, due to the large quantity of solid bodies used, the desired wear of the fabrics is essentially due to the friction of the fabric with said bodies.
  • This phenomenon is improved by the use of a liquid or an abrasive powder which tends to lodge in the concavities of the massive elements and to constitute reserves which are gradually released during periods of friction.
  • An important advantage provided by the method described above, is that it causes a softening of the laundry and avoids having to use softening agents.
  • the treatments carried out on the linen can also be carried out on other materials, such as leather, silk, pieces of canvas, etc.
  • the invention is not limited to a particular type of abrasive agent which can be used to obtain the desired premature wear phenomenon.
  • this abrasive agent may in particular consist of a liquid containing at least one enzyme complex prepared by fermentation of a strain of fungus, activators and regulators of the enzyme complex and a wetting agent.
  • this agent can be reinforced by increasing the quantity of solid elements and / or by introducing into the drum a powder having an abrasive effect and / or a material such as pumice stone.
