Abstract

This invention concerns a ozone injector system for injecting ozone into a dry cleaning machine after a solvent cycle has completed while recirculating solvent residual gas that has gravitated outside the dry cleaning machine. The invention comprises an ozone generator, an ozone injection assembly and a controller. The ozone generator is slideably positioned next to the dry cleaning machine while the ozone injection assembly is flexably connected to the ozone generator. The ozone injector assembly comprises a solenoid solvent valve and a solenoid ozone valve which are connected to each other by fixtures and communicate with each other via the controller to inject ozone after the solvent flow. The ozone generator further recirculates heavier than air solvent gas which gravitates outside the dry cleaning machine upon opening after the ozone cycle.
