  • an opening/closing valve 6a of the exhaust duct 6 may be provided.
  • valve 6a when the ozone is to be supplied, the valve 6a is closed and the exhaust system is not active.
  • the ozone can be introduced into the positioning area 4 in the submerged part in the first compound, in the part with air or steam (top) and/or in the present service pipes.
  • control unit is arranged to operate at different times or substantially simultaneously the dispensing of the first compound and of the ozone within the positioning area 4. If this dispensing occurs at different times, then, preferably, first the first nebulized compound is dispensed so as to wet or affect the manufactured articles and then the ozone is delivered on the items treated with the first nebulized compound.
  • the transmitting tube 11 can open into the tank 7 or into the conveying duct 9, so that the ozone is mixed with the first compound and subsequently the thus obtained mixture is nebulized and conveyed within the positioning area 4.
  • the apparatus 1 comprises at least one nozzle 12 supported by the frame 2 or by the door 5, which is arranged to dispense the first compound nebulized or in the form of droplets or microbubbles or nanobubbles in the positioning area 4, the nozzle/s 12 being then in fluid communication or served by the conveying duct 9 and, if provided, by the passage duct 8a or rather by the transport duct for the nebulized mixture and opens/open in the positioning area.
  • a nozzle or more nozzles are provided, for example two, three, four, five, six or more nozzles 12 supported by the door 5.
  • the door 5 can be provided with a porthole 5a for inspection of the positioning area 4 and one or more nozzles 12 can, for example, but not necessarily, be mounted or supported by the porthole 5a.
  • the porthole 5a can be provided in an upper area of the door 5.
  • the nozzles 12 have the main body mounted outside the positioning area 4 and the dispensing opening protruding within the positioning area 4, which opening is advantageously facing downwards or towards one side of the apparatus 1.
  • the apparatus may also include a container 14 of an ozone decomposition (in oxygen) substance in the first compound and in the manufactured articles, if desired for neutralizing ozone in water and in the items of clothing, as well as a destructive component 15 of the volatile or gaseous ozone present in the positioning area 4.
  • a container 14 of an ozone decomposition (in oxygen) substance in the first compound and in the manufactured articles if desired for neutralizing ozone in water and in the items of clothing, as well as a destructive component 15 of the volatile or gaseous ozone present in the positioning area 4.
  • the ozone is harmful for the environment and must be destroyed.
  • the destructive component 15 is essentially designed to decompose the ozone so as to generate oxygen.
  • the decomposition substance may comprise a compound selected from the group consisting of, for example, sodium metabisulphite, hydroxylamine, oxalic acid and hydrogen peroxide or other suitable chemical compounds.
  • the decomposition substance can be introduced into the positioning area 4 and then into the first compound and into the items of clothing therein automatically, through a respective duct, or even manually starting from a specific opening.
  • the decomposition substance is introduced in an amount of from 1 to 20 g per liter of first compound, if desired, water.
  • the apparatus 1 can also include hot and/or cold water inlet ducts, but also so-called “hard” or “softened” water or a variant thereof to the positioning area 4, which ducts are in communication with the traditional water supply network.
  • a method according to the present invention and including the steps here described is advantageously, but not necessarily implemented by means of an apparatus as described above.
  • the basket 3 is rotated, for example at a speed between 5 and 50 RPM for a time between 5' and 120', and keeping it into rotation for a determined period after delivery and feeding.
  • the first nebulized compound and the ozone could be delivered or fed into the positioning area and subsequently they act on the manufactured articles even when the basket is stationary or subjected to small movements/rotations.
  • the feeding of the first nebulized compound in the positioning area can be carried out in the following ways:
  • the treated manufactured articles or items of clothing are then extracted from the positioning area 4. If desired, it is also possible to provide a drying step for the manufactured articles or items of clothing in the positioning area 4.
  • a method according to the present invention can also be carried out in several apparatuses and therefore not necessarily in one apparatus as indicated above.
  • Such apparatuses should clearly not comprise all the components described above, but they could also comprise for example only the delivery system of the first compound, or only the ozone delivery system or only the rotating basket or two or more of these components.
  • such method for decoloring or treating manufactured articles could be carried out with at least two apparatuses, each comprising a main frame 2, a basket 3 defining a positioning area 4 of the items mounted within the frame 2, a door 5 pivoted or constrained to the main frame 2 and movable so as to open or close an access opening AA to the positioning area 4.
  • Such method could then include the following steps:
  • the first compound is dispensed in an amount between 0.1 and 3 litres for each kg of products and/or items of clothing placed in the positioning area 4.
  • the absorption ratio or the bath ratio i.e. the ratio between the weight of the items of clothing and the volume of the first compound, such as water in the positioning area, ranges preferably between 1:0.1 and 1:3.
  • the first compound is kept at room temperature.
  • the temperature in the positioning area during the method is the room temperature.
  • the compressed gas if provided, can instead be fed at a pressure between 0.5 and 8 bar.
  • this step can be carried out for example for a time between 5' and 120', depending on the desired effect.
  • the amount over time, for example in hours of injected ozone depends on the amount of manufactured articles or items introduced and on the type of ozone generator and on the model of washing machine/apparatus used.
  • the method after the other indicated steps, but before the extraction of the manufactured articles, involves the insertion in the positioning area 4 of the substance of decomposition of the ozone in the first compound and in the manufactured articles and a step of destruction of the volatile or gaseous ozone (fed to the chimney (s)) by means of the destructor component 15.
  • the first compound before being sent to the positioning area, by checking the appropriate electrovalves, is sent to the machine drain and then subsequently to the washing machine. This step is clearly optional and not essential.
  • control of the electronic valves, the rotation of the basket and the automatic operation of the apparatus is entrusted to the control unit.
  • control unit or PLC could be set up so as to be able to control the times, pressures and/or flow rates of the method.
  • the PLC could also make it possible to save the treatment configurations or "recipes", to then recall them during subsequent cycles.
  • a method according to the present invention has the advantage of ensuring a better decolorization or bleach effect because it is superficial and less aggressive and accelerated than traditional methods and therefore allows:
