Abstract
A commercial steam-cleaning laundry machine is configured to use steam instead of dry-cleaning chemicals or water as a primary cleaning agent for garments rotating in a drum of the commercial steam-cleaning laundry machine. In one embodiment of the invention, a steam injector at least partially exposed to an inner surface of the drum is configured to provide a MCU-controlled fresh steam injection into the drum during a cleaning cycle of the commercial steam-cleaning laundry machine. The fresh steam into the commercial steam-cleaning laundry machine is from an outtake of a standalone boiler system which is typically used for a variety of fabric treatment machines in a commercial laundry operation. A debris and clean steam/air separation chamber periodically or continuously separates and/or filters debris, chemicals, and/or other undesirable elements from the drum and evacuates clean or cleaned-up air and moistures to an air-out duct.
