MULTI-PHASE CIRCUIT FLOW-THROUGH HEATER FOR AEROSPACE BEVERAGE MAKER

摘要

A water heater for an aircraft beverage brewing apparatus includes a three way electrical conduit (12) for conducting electrical power in three separate phases. The heater has a housing (14) with a fluid inlet port at a first removable end piece (18) and a fluid outlet port (42) at a second removable end piece (20). The hollow cylindrical core incorporates a heating element wound around the core, and the housing includes three resettable temperature sensors at the outlet, each of the three resettable temperature sensors (24a, 24b, 24c) connected to a separate phase of power from the three way electrical conduit.
