摘要: Hot water in a supply tank (38) of coffee maker, (20) is dispensed through shut-off valve including tube (84) at uniform rate for preselected time period until the open inlet (84C) raised above surface level (110) to not only stop flow but also drain and steam clean any residual prevent formation mineral lime deposits which undesirably alter rate. A brewing strength by-pass assembly (80) passing diluted hot an urn (24A or 24B) drawn from temporarily collected bottom chamber (76) received into top (76A) as stream air pressure isolate control well mixing nozzle (116A), so that adjustment will create variation back The (116) has spouts (118) ends channels easy cleaning; it (116B) compensate reduced when closed maximum brew. dry ingredient held nondistorted filter conforms body holder (230) with by pass (240) laterally spaced formed square collar (234). upper draw hole (158) obtaining hotest faucet (36) while serving opening closure (160) handle (52) water. beverage maker housing made sheet metal parts single H-shaped part (176) forms substantial (22C), intermediate (22B) lower (22A) sections improved simplified assembly.
