Definitions

  • the present invention relates to the washing machine sector and, in particular, to the problem of disposing of the used washing liquid.
  • Machines for washing components in particular metal components for industrial use, are currently known, comprising a supporting frame which defines a tank or washing chamber and a mobile lid that can be opened and closed to allow insertion of the components in the tank, support means for the components in the tank and means which spray water and detergents dissolved in said water onto the components.
  • the present invention in accordance with claim 1, provides a method for disposing of the washing liquid in a machine for washing items, said machine comprising a chamber for washing the items, support means for at least one item in the washing chamber, means for the storage of a given volume of the washing liquid, means for bringing the washing liquid into contact with the item to be washed, and means for eliminating the washing liquid from the machine, characterised in that to eliminate the washing liquid from the machine, the liquid is at least partially evaporated, in order to reduce the volume of liquid to be eliminated.
  • the present invention also relates to a washing machine which implements the method according to the present invention.
  • FIG 1 illustrates a first preferred embodiment of the machine according to the present invention.
  • the machine 10 for washing items comprises a supporting frame 12, with feet 8, 9 which rest on the floor, defining a chamber 14 in which the items to be washed are housed by means of outer side walls, only walls 109, 110 and 111 illustrated in Figure 1, a base wall 11 and a mobile upper wall 15, defining a mobile lid, hinged to the wall 110 at 113.
  • the washing machine 10 also comprises means which support at least one item 18, in the form of a basket or support surface 16 located within the washing chamber 14 and rotated by a suitable motor 116 by means of a suitable transmission system, schematically illustrated using dashes and dots and labelled 117 in Figure 1.
  • the washing liquid (labelled with the numeral 20) is stored in a lower compartment or tank 14' in the chamber 14, and to bring the washing liquid into contact with the item to be washed, spray nozzles 21 are envisaged on the pipes 22, located around the support for the item 18 to be washed.
  • the item to be washed may be brought into contact with the liquid by immersing it directly in the latter rather than using a spray system.
  • the washing liquid preferably water and detergent and any other washing agents
  • the washing liquid is recirculated several times over the items to be washed and is used in several washing cycles to wash different components.
  • said residues for example, comprising various substances present on the components, such as greasy or oily substances, dust, metal chippings and other substances - the used washing water is eliminated from the machine and substituted with fresh, clean washing water.
  • means 26 are envisaged for evaporating, at least partially, said washing liquid 20, so as to at least partially reduce the quantity or volume of liquid to be removed from the chamber, for example, through the lower tap 27.
  • Said means for evaporating the liquid are a heating element 26 which heats the liquid and can also be used at a lower operating temperature to heat the liquid during the normal component washing stages.
  • Means for evaporating the washing liquid other than the electrical heating element may also be used for the present invention.
  • the present machine also comprises suitable means for controlling said means 26 which evaporate the washing liquid, comprising a control unit 28 electrically connected to the heating element 26 and a control knob 30 which allows said evaporation stage to be started.
  • the means 26 for evaporating the washing liquid 20 are left on at least until all of the washing liquid has substantially evaporated.
  • control knob 30 can be used to start the evaporation stage, for example, at night, outside of normal working hours, and the heating element left on until the start of the next shift.
  • the heating element is of the type which operates without causing any damage, even when the chamber is empty, that is to say, in the absence of water to be heated. This guarantees the almost total elimination of the washing water and a "dry" residue with greatly reduced volume is obtained, allowing easy treatment of the residues.
  • the storage compartment 14' for the washing liquid extends below the washing chamber 14 and has a base wall 13 and outer side walls, of which only walls 149, 151, 152 are illustrated in Figure 1.
  • the top of said compartment 14' opens into the chamber 14, from which it is separated by a removable wall or panel 11' with a central trap filter 29 through which the liquid 20 sprayed onto the item descends into the compartment 14'.
  • the present machine also comprises means 32 for recirculating the liquid 20 from the storage compartment 14' to the sprayers 21, said means comprising a recirculating pump 33 with an intake pipe 34 whose inlet, fitted with a filter 36, is located in the lower compartment 14' which stores the washing liquid, and a delivery pipe 38 directly connected to the pipes 22 of the sprayers 21.
  • the liquid evaporation means 26 are located close to the base 13 of said lower liquid storage compartment 14'.
  • means 40 are envisaged to allow the discharge of the vapour produced by the evaporation of the washing liquid 20 within the chamber 14.
  • Said means for the discharge of the washing liquid 20 vapour take the form of a centrifugal extractor 40 which draws the vapour through an opening 42 in the side wall 110 of the chamber 14 and, through a pipe 44, which may be fitted with filters for the vapour, directs it to the outside of the building in which the machine is installed.
  • the vapour extracted by the extractor could also be condensed in a separate condensation tank 70, as illustrated in Figure 1.
  • the extractor means for the vapour produced are advantageously activated and controlled by the means 28 and 30 which control the heating element 26.
  • means 46 are also envisaged for collecting and supporting the solid or pasty residue which remains after the washing liquid has evaporated.
  • Said means 46 for collection of the residue are a bag whose lower part 48 is at the base 13 of the liquid storage compartment 14'.
  • the side 50 of the residue collection bag extends over at least part of the side walls of the compartment 14'.
  • the collection bag 46 extends alongside the heating means 26, which are covered by a protective cage 31 to prevent contact with the bag 46.
  • the bag 46 is made of a material which is permeable or porous, allowing the passage of the washing liquid, for example a fabric such as cotton or others, designed to filter the liquid.
  • the inlet 36 of the washing liquid recirculating means is located above the collection means 46.
  • the bag 46 can be extracted or removed from the machine, so that it can be substituted with a new bag for the residues.
  • Means for supporting the collection means 46 are envisaged, in the form of a quadrangular bracket 52 which, thanks to projections 54 can be attached to or removed from the lower compartment 14' inside the chamber 14.
  • the bag 46 is fixed to the bracket 52 in such a way that it may be removed, allowing easy substitution.
  • the bag is removed by the operator, who reaches through the upper opening, of the chamber normally closed with the lid 15, and, after removing the mobile base wall 11', lifts the bracket 52 with the solid residues held inside the bag 48.
  • Figure 2 illustrates a second preferred embodiment of the washing machine according to the present invention.
  • Figure 2 illustrating the second preferred embodiment of the machine, the elements similar to those in the first preferred embodiment are labelled using the same numerals as in the previous figure and, so that the present description is not too lengthy, are not described again.
  • the second preferred embodiment differs from the first preferred embodiment in that, at the base 13 of the compartment 14', below said first means 46 for collection of the residues, there are second means 202 for collection of the residues, which pass across said first collection means 46.
  • Said second collection means are a bag 202, made of a plastic material impermeable to the liquid, supported by a quadrangular supporting bracket 204 which can be attached to projections 206 substantially at the base 13 of the compartment 14' and can be detached from said projections to allow the removal and substitution of the plastic bag 202 following removal of the upper bag 46.
  • the second preferred embodiment also envisages that the part 50 of the porous bag 46 extends completely above the protective cage 31 over the heating element 26.
  • the washing chamber 14 is quadrangular in shape and the compartment or tank 14' is also quadrangular, although shorter, leaving a lateral space below the chamber 14 so that the various means used to drive the machine can be housed there.
  • the compartment 14' could have a different shape to the quadrangular shape illustrated, for example, cylindrical, conical, or other shapes.
  • the machine referred to in the present invention is preferably used to wash metal components for industrial use. However, it could be adapted to make it suitable for washing any type of item, such as pans, crockery, fabrics and others.
  • the washing machine could also use and evaporate solvent washing liquids other than the water described herein.
