Boiling water dispenser having improved water temperature control system

A sensor assembly for a boiling liquid apparatus having a liquid reservoir and vent tube providing a vent opening for steam generated by the boiling of liquid within said reservoir, said assembly comprising mounting means of thermal insulating material supported on said vent tube, a sensor having a temperature responsive body supported by said mounting means in alignment with said vent opening and connectable with means for controlling heating of the liquid within the reservoir, said air around said sensor for cooling the sensor in the absence of steam emitting from said vent opening.

A sensor assembly for a boiling liquid apparatus having a liquid reservoir and a vent tube providing a vent opening for steam generated within the reservoir upon boiling of liquid therein, said assembly comprising a first pair of mounting members embracing said tube adjacent said vent opening, means releasably clamping said pair of members to said tube, a pair of clamping members releasably clamped together and secured to one of said first mentioned members, a sensor comprising a temperature responsive thermister body and electrical leads extending from opposite ends thereof and secured between said clamping members, said thermister body being supported substantially in alignment with said vent opening.
