INCREMENTALLY HEATED FLUID DISPENSER WITH NON-VOLATILE CONSTITUENT PARTS

摘要

The present invention discloses a method and apparatus for quickly heating a predetermined volume of viscous fluid and dispensing it efficiently at one o r more selected temperatures. The viscous fluid includes non-volatile constituent parts. In one embodiment, the predetermined volume of viscous fluid is partially housed in a predelivery chamber (836) separate from the main fluid reservoir (860). A heater assembly (816) heats the viscous fluid in the predelivery chamber in a short time period and in small volumes to preve nt overheating and adversely effecting the composition of the viscous fluid. To avoid continually heating the viscous liquid, a timer circuit (912) is used in one embodiment.
