Fabric articles dry cleaning machine by solvent nebulization

A dry cleaning machine including the use of solvent nebulization for drycleaning textile articles, consisting of:

• a cleaning chamber, and means associated with said cleaning chamber including a rotatable cylinder (22) in which the fabric articles are contained and means to drive the cylinder in a rotatory motion, a clear liquid solvent and at least one nozzle (35) through which said clear liquid solvent is nebulized and with means for supplying hot or cold air circulating within a sealed air circuit and conveyed into the cylinder, for cleaning and removal of dirt and solvent based on the solvent action of the nebulized solvent drops which are uniformly distributed directly onto the entire surfaces of the textile fabric articles by means of a contemporary intake of the air flow circulation through the forced air inlet duct (42) and then the dirt and nebulized solvent drops are moved directly through a suction duct (38) out of the cleaning chamber and piped again in the sealed air circuit system for the regeneration of the solvent used for the cleaning action and the recovery of dissolved and non-dissolved dirt retained by the solvent drops transported by the air flow;
• and
• a circuit for the cleaning of said at least one nozzle to provide an exclusive circuit in combination with a uniform distribution of the solvent and to prevent residual nebulized drops from staining the fabric articles during the drying phase.

A dry cleaning machine for dry cleaning textile fabric articles by solvent nebulization comprising:

• means including a closed and sealed air circulation system for recirculating air comprising sealed drying-duct (30) associated with a door (32), equipped with a forced air inlet duct (42), an air inlet duct (24), a suction duct (38), a treatment chamber (21) in the form of a barrel including a cylinder (22) for receiving the textile fabric articles to be cleaned and means to drive said cylinder (22) in a rotary motion, an impeller (26), heat exchange coils (25, 27, a refrigerator apparatus (29);
• a clear-liquid-solvent and at least one or more nozzles (35) through which said liquid solvent is nebulized to obtain solvent nebulized drops (44) so that dirt which is on the surface of the textile fabric articles and in openings or pores of the textile fabric articles is dissolved and/or broken loose is retained and encapsulated by the small drops of solvent which are transported by the air flowing through the closed air circulating system outside of the treatment chamber (21) for removal of the dirt from the openings, pores and surface of the textile fabric articles and condensing the nebulized solvent drops containing melted dirt in a heat exchanger inside of the sealed drying duct (30) connected to the treatment chamber and recovering the condensed solvent drops in a separator;
• and
• comprising the step of using said solvent nebulization and including a circuit for the cleaning of nozzles to prevent nebulized solvent drops from staining the textile fabric articles.

• the dry cleaning machine is free of any distilled apparatus for cleaning and regeneration of the liquid solvent by providing a new washing process for separating non-soluble dirt from soluble dirt in different phases with an air intake being provided to remove hairs, dust and other dirt through a forced air intake duct (42) and including a button trap (37) for storing the removed hairs, dust and other dirt in said button trap (37), then nebulizing the liquid solvent through said at least one nozzle (35) and while said cylinder (22) is rotating the solvent is nebulized to produce small drops together with a contemporary intake of hot air through the forced air inlet duct (42) for a uniform distribution of the nebulized solvent onto the fabric articles and such flow of the hot air provides for the transportation out from the treatment chamber solvent drops containing melted dirt by the hot air and which passes through the suction duct (38) where part of the non-soluble dirt is retained in filtering apparatuses (36)(37), the soluble dirt is then condensed in a heat exchanger (27) and recovered in a separator (10) and then the soluble dirt enters into a containment tank (45) from which the solvent is passed by a pump (4) through a clay or paper carbon cartridge filter (12) for removing any remaining part of the soluble dirt which is non-soluble dirt during the cleaning and drying process.

• and
• drying means for carrying out the drying phase consisting of a sealed drying duct (30), an impeller (26) and a refrigerator apparatus (29) connected with an heat exchanger (25) in which the hot compressed refrigerator gas is circulating, to provide for the necessary heat for the drying phase, and connected to the heat exchanger (27) in which the cold expanded refrigerator gas is circulating, for condensing and recovering the solvent during the drying phase.
