It has perforate bottom wall and side walls and an open top and is generally symmetrical about x, y, and z axes that are orthogonal to each other. The basket may be manually compressed alone these axes and then allowed to return to its normal shape when released. Thus, it has a non-compressed, relaxed state wherein it has maximum exterior dimensions and can stand-alone and serve the normal functions of a basket. The basket also has a compressed condition wherein at least certain of the dimensions of the basket are less than said maximum dimensions so that it can be fitted into a dryer, allowed to expand, and serve as a dryer liner. Wet clothes and other items can then be placed in the basket through the dryer opening in the normal manner.

The apexes further provide an increased air gap for increased airflow radially across the electrical insulators. The heater housing has an air gap with the rear end head of the dryer drum which air gap is smaller adjacent the upper portions of the heater housing so as to reduce the chimney effect associated with the air heated in the heater housing.

Abstract: To permit the use of combustible and potentially explosive solvents used in dry-cleaning operations, based on hydrocarbon compounds, the dry-cleaning machine is formed with an explosion-resistant housing (8) surrounding a perforated, rotatable drum (1) into which the goods are introduced. After carrying out the normal dry-cleaning procedure, and draining of dry-cleaning solvent, a vacuum pump generates an under-pressure, in the order of below 500 mbar, and preferably about 230 mbar, while heating the mixture to effect drying. A cooling coil, located at a lower portion of the machine, provides for condensation of solvent out of the solvent-air mixture and, after the major portion of the solvent has been evaporated, the heat exchanger is switched over to cooling for final condensation of any remanent solvent. The vacuum continues to be maintained, so that the boiling point of solvent, due to the under-pressure, is lowered by at least 40.degree. C., and preferably 50.degree. C.
