Abstract
A diffuser with an absorbent substrate for holding a steam diffusible composition, such as a fragrance for mounting on a steam frame of a steam appliance is provided. The steam appliance has a water pump for selectively injecting water from a reservoir to a boiler to generate steam fed into a steam frame with a fabric pad or steam pocket mounted thereon. The steam envelopes the diffuser to dispense a fragrance or other material in the absorbable substrate into the generated steam in response to a user use or movement of the appliance. When steam is generated and passes the diffuser, the composition is heated to a temperature it will vaporize and be distributed with the steam through the fabric pad or steam pocket.
