ABSTRACT:
A chemical washing system is presented including a chemical dispensing system. The chemical dispensing system includes a container for storing a liquid chemical, a dispensing unit coupled to the container for dispensing the liquid chemical, and a conduit for conveying the liquid chemical from the dispensing unit to a receptacle of a machine which uses the liquid chemical during normal operation. The container, the dispensing unit, and the receptacle may be enclosed within one or more service areas separate from a "user interface area" containing a portion of the machine with which a user interfaces during normal operation. In order to prevent airborne particulates and other contaminants within the one or more service areas from entering the user interface area, a positive air pressure differential is maintained between the user interface area and the one or more service areas. The chemical washing system includes a textile laundering appliance (e.g., a washing machine) having two opposed sides: a loading side for loading textiles into the washing machine and an unloading side for unloading textiles from the washing machine. The washing machine may be located within the clean room, and may be used to launder clean room garments. The chemical dispensing system delivers a liquid chemical (e.g., detergent) to the washing machine. The washing machine may be a washer/extractor including a manual dispensing port which functions as the receptacle.
