Definitions

  • the object of the present invention is a method for controlling washing of particular garments in a Washing Machine.
  • some kind garments as for example jackets, some trousers, clothes and so on, are generally dry cleaned or at least washed in industrial washing machine. This because they are particularly delicate garments which can be irremediable damaged with a traditional washing program.
  • Document EP 0 038 671 A2 relates to a method of washing textile articles that provides considerable saving in energy due to low temperatures of the washing liquid and to long durations of the mechanical agitation.
  • the aim of the present invention is to provide a control mode of a washing machine that allows the washing of delicate garments such as trousers, jackets, dresses etc.. without industrial washing machine.
  • the basic idea of the present invention is to provide a wash cycle whose temperatures are constantly kept at low heat and in which, the rotational movements of the garments inside the drum of the machine, are quite soft, and in the meantime a considerable amount of water is used.
  • object of the present invention is a method for controlling a washing machine comprising the execution of a wash cycle wherein:
  • At least a rinse step is performed, and preferably two rinse steps are performed.
  • the rotational movements of said drum last for a time comprised between 2 and 5 seconds.
  • the rotational movements of said drum are alternated to steps wherein said drum is substantially motionless.
  • the steps in which said drum is substantially motionless last for a time comprised between 20 and 40 seconds.
  • the speed of rotation of said spin is below 90 rpm.
  • each rinse step is followed by a step wherein said drum rotates at a speed not exceeding 35 rpm.
  • the control method, object of the present invention comprises, first of all, the step of providing a quantity of water of at least 20 litres, loaded in the drum of the washing machine.
  • the amount of water can be equal to 23 litres.
  • the water is later heated until a not particularly hot temperature, for example less ore equal to 25°C.
  • a series of rotational movements of the machine drum are then performed at a speed not exceeding 35 rpm;
  • the rotation movements of said drum are advantageously alternated to steps wherein said drum is substantially motionless.
  • the steps wherein the drum is motionless go on, at least 7-8 times longer than the ones of the rotational movements.
  • the rotational movements of said drum last for a time comprised between 2 and 5 seconds and the steps in which said drum is substantially motionless last for a time comprised between 20 and 40 seconds.
  • the series of rotational movements of the drum for example, can have a duration of between 30 and 35 minutes, while the entire wash cycle can last up to 100 minutes about.
  • one or more rinsing steps are performed after said rotational movements of the drum.
  • two rinsing steps can be performed.
  • each rinse step is followed by a step where the drum is rotated at a speed not exceeding 35 rpm.
  • the speed of rotation of the spin is below 90 rpm, for example is equal to 88 rpm.
  • the spinning step is performed at a speed equal to, or very close, to the minimum speed, so that, the spin force used is able to balance the force of gravity acting on the garments in the drum.
  • This quantity may be, for example, less than 2 kg, and in particular not more than 1.5 Kg.
  • Figure 1 shows explicative charts representing the execution of the washing method according to the invention.
  • the horizontal axis represents time
  • the ordinate axis represents the water consumption of the machine (A)
  • the electrical power absorbed by the machine (B) the wash water temperature (C) and the speed of rotation of the drum (D).
  • A1 is the water loaded at the start of washing
  • A2 and A3 identify the rinse steps performed at the end of the cycle.
  • D1 identifies the number of rotational movements at reduced speed
  • D2 identifies the movements associated with the rinse steps
  • D3 the final step of spin/satellization.
