Definitions

  • the invention relates to a method for the treatment of laundry in a laundry washer/drier combination, to be executed subsequent to the laundering operation for preparing the laundry for the execution of an effective drying operation.
  • Known laundry washer/drier combinations are designed for the sequential execution of laundering and drying operations.
  • the drum containing the laundry is rotated at a low laundering speed in alternating directions, and during the final rinsing operation, it is rotated at an increased spin-drying speed for effectively squeezing the laundry partly dry prior to its being dried in the conventional manner.
  • the rotation of the drum at the spin-drying speed may, particularly in the case of machines operating at very high spin-drying speeds of the order of 1200 to 1500 upm, lead to the undesirable result of the laundry adhering to the inner walls of the drum, giving rise to difficulties with regard to detaching the laundry from the drum walls at the end of the spin-drying operation.
  • the laundry may exhibit the tendency to accumulate in separate areas of the drum's inner wall, rather than being evenly distributed over the entire area of the inner wall surface of the drum as would be desirable for permitting it to be rapidly and substantially uniformly dried.
  • the uneven distribution of the laundry may again result in its being yellowed and/or partially scorched in the course of the subsequent drying operation.
  • This laundry treatment method is particularly applicable to laundry washer/drier combinations operating at elevated spin-drying speeds of the drum and includes the execution at the end of the various laundering operations of any selected laundering cycle of the operative steps to be described as follows:
  • the operative steps of the present laundry treatment method are initiated subsequent to the charge of water for the final rinsing operation having been admitted to the tub enclosing the drum containing the laundry, by rotating the drum at a low speed in alternating directions.
  • this final rinsing operation is indicated at A and has a duration of for example three minutes, during which the drum is rotated at a speed of 55 upm. with its direction of rotation being reversed at 8 sec. intervals.
  • the rinsing water is completely discharged from the tub during a period indicated at B and having a maximum duration of for example 20 to 40 sec..
  • the drum continues to be alternatingly rotated at low speed, in the present example for 4 sec. in one direction and for 12 sec. in the opposite direction, at a speed of 55 upm..
  • the drum is rotated in a series of short bursts of progressively increasing spin-drying speeds separated from one another by intervals during which the drum is rotated at low speed in alternating directions.
  • the present method provides the execution of four such spin-drying bursts at rotary speeds of 400, 600, 800 and 1000 upm..
  • the drum is initially rotated at a low speed of in the present example 55 upm, with only a single rotation in each direction for a duration of 3 sec., followed by a short burst, in the present example of a duration of 4 sec., of rotation at the spin-drying speed rapidly attaining a maximum of 400 upm., whereupon the electric motor of the machine acting to rotate the drum is deenergized to permit the rotary speed of the drum to drop to the previous value.
  • the drum is initially rotated at the same low speed of in the present example 55 upm, the direction of rotation being reversed five times at 3 sec. intervals, followed by a short burst, with a uniform duration of 4 sec., of spin-drying rotation at maximum speeds of 600, 800 and 1000 upm, respectively, whereupon the rotary speed is again reduced to the previous value.
  • the drum is initially rotated at the low laundering speed of in the present example 55 upm, with the direction of rotation being reversed at intervals of 12 and 4 sec. respectively, followed by its rotary speed being gradually and linearly increased to a value of in the present example 85 upm, which is then maintained for the remainder of this second step for permitting a uniform distribution of the laundry over the inner walls of the drum to be established.
  • the drum is exclusively rotated at the spin-drying speed which is progressively increased from an initial value to a final value, in the present example from 650 upm to 1500 upm.
  • the third step is in the present case subdivided into seven consecutive periods designated by reference letters H, I, L, M, N, O, P, the first such period having a duration of 10 sec, while the duration of the remaining periods is 50 sec each.
  • the rotary speed of the drum is rapidly increased from the previously attained value of 85 upm to a spin-drying speed of 650 upm, which is held for a short instance, to be subsequently again rapidly increased to the higher spin-drying speed of 85o upm, which is then again held for a short instance.
  • the rotary speed of the drum is rapidly increased from the previously attained value to a faster spin-drying speed of in the present example 900 upm, which is then held constant for the remainder of this period of the third step.
  • the rotary speed of the drum is rapidly increased from the previously attained value to a somewhat faster spin-drying speed of successively 1000, 1100, 1200, 1400 and 1500 upm, the respective rotary speeds thus attained being maintained constant throughout the respective periods of this step.
  • This sequence of spin-drying operations is conducive to obtaining an efficient squeeze-drainage of the laundry and a uniform distribution of the laundry on the inner walls of the drum rather than localized accumulations thereof.
  • the present treatment method finally provides the execution of a fourth and a fifth step indicated respectively at Q and R and having a durction each of 10 min in the present example.
  • the drum is rotated at a low speed of about 30 to 35 upm in alternating directions, in the present example for 4 sec in one direction and for 12 sec in the opposite direction, while during the fifth step, the drum is still rotated at a low, albeit somewhat higher speed of 55 upm, the direction of rotation being reversed at regular 10 sec intervals.
