Coffee brewer

Abstract

Abstract A NO-DRIP SIPHONLESS BEVERAGE MAKER, FOR MAKING COFFEE AND THE LIKE, INCLUDES A TANK OF HEATED WATER WHICH CAN BE SELECTIVELY DISCHARGED FROM THE TANK THROUGH THE MATERIAL FROM WHICH THE BEVERAGE IS MADE. IN ADDITION TO A THERMOSTATICALLY CONTROLLED HEATER LOCATED IN HEAT TRANSFER RELATION WITH WATER IN THE TANK FOR HEATING THE WATER IN THE NORMAL MANNER, MEANS ARE PROVIDED TO MAINTAIN THE TOP OF THE TANK CONTINUOUSLY HEATED TO PREVENT THE ACCUMULATED AIR FROM CONTRACTING DURING THE BREW CYCLE. THIS MAY BE EFFECTED BY USE OF A SEPARATE BAND HEATER AT THE TOP OF THE TANK, BY SELECTIVE POSITIONING OF THE THERMOSTATICALLY CONTROLLED HEATER OR BY USE OF HEAT INSULATION MEANS AT THE TOP OF THE TANK. DURING THE BREW CYCLE, HOT WATER IS DISCHARGED FROM THE TANK IN THE NORMAL FASHION, BUT IN ADDITION, SUFFICIENT AIR IS RELEASED AT THE TOP OF THE TANK DURING THE CYCLE TO INSURE THAT THE AIR BARRIER BETWEEN THE TOP OF THE TANK AND THE WATER IS MAINTAINED AT THIS PORTION OF THE TANK. THIS KEEPS THE LEVEL OF THE WATER IN THE TANK AT THE LEVEL OF THE OPENING OF THE HOT WATER DISCHARGE TUBE, THEREBY PREVENTING DRIPPING AT THE END OF THE BREW CYCLE.
