Machine for dry-cleaning articles

Abstract

The machine ( 1 ) for dry-cleaning and drying articles such as clothes, household linen, towels, curtains and the like comprises a rotary drum ( 2 ) which contains the articles, a hydrocarbon—solvent feed and recovery circuit ( 16 ), a powder filter ( 22 ) and a cartridge filter ( 122 ) for filtering the hydrocarbon—solvent.

1 . A machine for dry-cleaning articles such as clothes and the like, comprising:
 a rotary drum ( 2 ) for containing the articles,   a solvent feed and recovery circuit ( 16 ) to and from the rotary drum ( 2 ), the machine being characterised in that it comprises a first, powder filtering device ( 22 ) for the solvent and a second, cartridge filtering device ( 122 ) for the solvent, the devices ( 22 ,  122 ) being positioned along the circuit ( 16 ).   
   
   
       2 . The machine according to  claim 1 , characterised in that the first, powder filtering device ( 22 ) and the second, cartridge filtering device ( 122 ) are positioned parallel with one another so that they can operate alternatively to one another. 
   
   
       3 . The machine according to  claim 1 , characterised in that, for each filtering device ( 22 ,  122 ) it comprises at least one respective solvent tank ( 14 ,  15 ,  17 ), each tank ( 14 ,  15 ,  17 ) being selectively in fluid connection with only one of the filtering devices ( 22 ,  122 ). 
   
   
       4 . The machine according to  claim 1 , characterised in that the solvent feed and recovery circuit ( 16 ) comprises a first inlet stretch ( 16   a ) along which the first filtering device ( 22 ) is positioned, and a second inlet stretch ( 16   b ) along which the second filtering device ( 122 ) is positioned. 
   
   
       5 . The machine according to  claim 4 , characterised in that, for each of the inlet stretches ( 16   a ,  16   b ) of the feed and recovery circuit ( 16 ), it comprises a respective solvent circulating pump ( 19 ,  119 ). 
   
   
       6 . The machine according to  claim 5 , characterised in that it comprises, extending from the second inlet stretch ( 16   b ), a second, cartridge filtering device ( 122 ) bypass duct ( 100 ). 
   
   
       7 . The machine according to  claim 1 , characterised in that it comprises means ( 23 ) for cooling the solvent to be fed to the drum ( 2 ). 
   
   
       8 . The machine according to  claim 7 , characterised in that the cooling means ( 23 ) are positioned along the feed and recovery circuit ( 16 ) downstream of the first and second filtering devices ( 22 ,  122 ). 
   
   
       9 . The machine according to  claim 1 , characterised in that it comprises an element ( 28 ) for collecting the powders discharged from the powder filtering device ( 22 ) and drying means ( 38 ) for drying said powders in the collecting element ( 28 ).
