Abstract
A dry cleaning machine for articles such as garments and the like, comprises: a rotary drum for containing the articles; means for feeding a solvent into the drum; means for draining a solvent out of the drum; a closed circuit for circulating air for drying the articles inside the drum, comprising at least one air movement fan, means for driving the fan, a heating device for heating the air to be fed into the drum, an air cooling device for condensing the solvent contained in the air flowing out of the drum.
Claims17
A dry cleaning method for articles, comprising:
- feeding a solvent into a drum for containing articles;
- rotating the drum in order to distribute the solvent on the articles;
- causing a drying air flow to circulate along a closed circuit including the drum, in order to dry the solvent from the articles;
- heating the air circulating in the closed circuit upstream of the drum and cooling the same air downstream of the drum;
- varying a speed of air circulation along the closed circuit during the circulating the air flow along the closed circuit;
- detecting a value of solvent concentration in the air circulating in the closed circuit, wherein the varying the speed of air circulation along the closed circuit comprises varying the speed of air circulation according to the detected value of solvent concentration in the air circulating in the closed circuit, wherein the solvent is dibutoxymethane.
