Definitions

  • the present invention relates to a laundry treatment household appliance according to the preamble of claim 1.
  • the appliances according to the present invention are washing machines, washing/drying machines and clothes dryers, and therefore are used for carrying out laundry washing and/or drying processes.
  • Such appliances are fitted with a rotating drum adapted to contain the laundry to be treated.
  • the drum rotates and the laundry items hit the inner surface of the drum. Such hitting may cause slight damages to the laundry items.
  • the things being most subject to damage are those rigid elements applied to laundry items, such as buttons and zippers; some types of slight damage to the fibres of the fabrics of laundry items may also be caused by water-soaked (i.e. heavy) laundry hitting the inner surface of the drum.
  • the present invention is based on the recognition of the importance of this slight damage.
  • the object of the present invention is to solve such problems in a simple and economical way.
  • the idea at the basis of the present invention is to use soft and/or elastic elements inside the drum of the household appliance.
  • Fig. 1 shows a washing machine 1 of the front-loading type; being a sectional view, the door glass bowl is not visible.
  • the present invention is not limited to front-loading washing machines; on the contrary, it is altogether independent of the drum loading type and position.
  • the washing machine 1 is fitted with a drum 2 adapted to contain the laundry to be washed, designated 3 in the illustration.
  • the drum 2 can rotate about an axis 20; the axis 20 is horizontal in Fig. 1.
  • the present invention is not limited to washing machines having a horizontal rotation axis; on the contrary, it is altogether independent of the direction of the drum rotation axis.
  • Fig. 1 corresponds to a condition wherein the drum 2 is stationary and the laundry 3 accumulates on the bottom of the drum 2.
  • lifters 4 On the inner surface of the drum 2 there are lifters 4, i.e. those elements that drag and lift the laundry during the treatment processes carried out by the washing machine.
  • the lifters are three and are applied to the drum 2; solutions are known which use a different number of lifters (e.g. four or five); in other known solutions, the lifters are obtained directly on the drum by appropriately shaping the inner surface of the drum itself.
  • the drum is made of stainless steel and the lifters are made of plastic; drum and lifters are therefore quite hard and rigid.
  • Fig. 2 shows an embodiment example of a washing machine 1 according to the present invention; the difference from the washing machine according to the prior art, shown in Fig. 1, lies in the drum.
  • the inner surface of the drum 2 is almost completely covered by three mats 6 made of a soft and elastic material, applied to the surface of the drum 2.
  • the lifters 4 are coated with a layer 5 of soft and elastic material, applied to the surface of the lifters.
  • Fig. 2 solves both the problem of the slight damage caused by hitting and the problem of the slight damage caused by dragging.
  • the laundry items may suffer slight damage as the drum rotates during the treatment processes.
  • the laundry treatment household appliance comprises a rotating drum adapted to contain the laundry to be treated and fitted on the inside with soft and/or elastic elements.
  • the element is elastic, when hitting the laundry it will change its shape without damaging the laundry, and subsequently will regain its original shape.
  • the simplest and most economical method for obtaining softness and/or elasticity consists in using a soft and/or elastic material.
  • the elements inside the drum may be made of several different materials.
  • the above-mentioned elements protrude from the inner surface of the drum of the household appliance.
  • these elements are adjacent to the inner surface of the drum.
  • the above-mentioned elements may be mats, e.g. like the mats 6 shown in Fig. 2.
  • the soft and/or elastic mats mainly solve the problem of damage caused by hitting.
  • the mats may vary in size, be more or less protruding from the inner surface of the drum, and be either solid or holed.
  • the mats may also be shaped in such a way as to obtain pleasant aesthetic effects.
  • the above-mentioned elements may be lifters; for example, these may be made as shown in Fig. 2, with a layer 5 of a soft and/or elastic material.
  • the soft and/or elastic lifters mainly solve the problem of damage caused by dragging.
  • the lifters may be diversely arranged in the drum.
  • drum according to the present invention there may be one or more soft and/or elastic elements; these may also be different from one another.
  • the element is wholly made of a soft and/or elastic material.
  • An example of such an element is shown in Fig. 3A, and corresponds to a lifter.
  • the element is made up of a first portion preferably made of a hard and/or rigid material and a second portion made of a soft and/or elastic material. Examples of such elements are shown in Fig. 3A and Fig. 3B, and correspond to lifters; the first portion is designated 8B and 8C, respectively, whereas the second portion is designated 7B and 7C, respectively.
  • said first portion may be provided in the traditional way, i.e. made of plastic, or else be made of metal.
  • Said second portion may consist, for instance, simply of a coating layer, as shown in Fig. 3C.
  • FIGs. 3A, 3B and 3C represent (in a very schematic way) sectional views of lifters applied to the inner surface of a drum (indicated with a straight and horizontal line).
  • the lifter end is rounded to avoid any risk of damage to the laundry items.
  • This application may advantageously be obtained through the first portion of the element, especially if it is made of a hard and rigid material; in fact, by so doing it is possible to obtain a very strong fastening.
  • the present invention may be applied to household appliances.
  • the choice of the elastic and/or soft material is important.
  • a material which has proven to be particularly suited to the present invention is produced by Bayer Polymers under the name "Desmopan DP 9370AU”.
  • the material for the drum elements should be sufficiently soft, elastic, and resistant to abrasion and tear.
