Definitions

  • the invention in a general manner, refers to laundry machines and, more particularly, to machines of the top-load wash and dry type to which a drying fin is associated.
  • the invention also refers to drying fins applied to said machine and used in the laundry drying cycle.
  • Laundry washing machines are domestic utensils widely used in assisting in the task of cleaning clothes and other fabrics used in a household.
  • laundry washing machine embodiments the best known of which consist of wash tubs, front-load machines and top-load machines.
  • wash tubs are generally a device substantially in the shape of a common wash tub, but that have a small turbine coupled to a motor, both mounted on the lower portion of the tub.
  • the motor with the turbine only has the function of agitating the water contained inside the tub in order to assist in the process of washing the fabrics, but other automated functions relating to the washing cycle, such as rinsing, spinning etc. are not present.
  • wash tubs are normally simple devices, and also do not present compartments specific for storing and dispensing products for cleaning and care of the laundry, such as powder, softener, bleach, etc.
  • washing machines that comprise full wash cycles, such as wash, rinse, spin cycles etc.
  • the so-called front-load machines present an opening and a door for access to the inside, where there is located the washing drum, at its front part, while in top-loaders, access inside the washing compartment is by an opening in the upper portion of the machine.
  • the working principle of these washing machine models is similar, and consists of a perforated drum, in order to allow the passage of water and/or cleaning agents of the fabrics, generally rotating both clockwise and anti-clockwise.
  • the laundry contained inside the drum is immersed in water with the cleaning agent, and the rotary drum turns the laundry in an alternate cycle, creating an agitation that helps in the cleaning of the fabrics.
  • the drum rotates in one direction only at a relatively high rotation, such as 500, 1 ,000 rpm or more.
  • front and top-load machines present similar working principles, as described above, there is a substantial difference in relation to their construction.
  • the rotation axis of the drum is in a horizontal position centralized thereto, and the laundry churns inside the drum due to the action of gravity, that is, the laundry inside the drum has a natural tendency to displace to the lower part of the drum when it turns. Fins mounted on the inner sides of the drum can also be used to help jolt the laundry on the inside.
  • top-load machines the rotation axis of the drum is in a vertical position.
  • said top-load machines generally have a central element mounted inside the drum and coinciding with the centerline of the rotation axis of the drive motor.
  • This element can be an impeller or an agitator.
  • the agitator as the name itself suggests, has the function of jolting the water inside the drum and implementing the mechanical action of the laundry in order to assist in cleaning the fabrics and preventing the laundry from clumping in the lower portion of the drum.
  • the agitators it is common for the agitators to have hydrodynamic profiles to promote the agitation of the water and the fabrics inside the drum when immersed in water.
  • washing machines that combine a dry cycle after the washing cycle, called "wash and dry machines”.
  • these types of combined machines are presented in a front-load arrangement, since for the dry cycle, it is also necessary to jolt the laundry inside the drum, otherwise drying would be inefficient.
  • front-load machines the laundry is naturally jolted inside the drum due to the action of gravity.
  • the top-load wash and dry machines since in the dry cycle there is no water inside the drum, the laundry tends to clump together at the bottom of the drum. Consequently, the dry cycle is adversely affected, since the laundry, tangled at the bottom of the drum, does not allow suitable passage of the air between the fabrics, hampering the removal of humidity and, therefore, the drying of the fabrics.
  • the agitator would have little function, since there is no water inside the drum and, therefore, there would be no way of jolting the fabrics.
  • drying chiefly when using fine or woolen fabrics, may damage the fabric or crimple it, an undesirable fact notably because additional work would be required to iron the laundry to restore the adequate and smooth appearance of the fabric.
  • Laundry or fabric terms used indistinctly herein for any object, such as, but not limited to, blouses, shirts, pants, bedspreads, sheets, pillow cases, table cloths and towels, tennis shoes, etc., that has, at least in part, a fabric in its composition that can be washed in the presence of water.
  • - Cleaning agents any product used for the care and cleaning of a fabric, such as soap powder, liquid soaps, concentrated soaps, softeners, bleaches, stain removers, whiteners, indigo, etc.
  • Washing cycle refers to an operation or a set of operations used in the cleaning and care of fabrics, such as washing, rinsing, spinning, etc. regardless of repetition of these operations or their duration time.
  • Dry cycle defined as the operation for drying a fabric, generally employed after washing, that may consist of the use of air flow, heated or not, containing water vapor or not.
  • Fine fabric fabrics such as silk, lace, crochet, synthetic fabrics, fabrics used in underwear and sleepwear laundry, etc. requiring special care for washing or drying in order to avoid damage thereto.
