HEATERS FOR LIQUID HEATING VESSELS

摘要

A heater (2) for a liquid heating vessel comprises a base plate (4) for forming at least part of a base of the vessel. A generally arcuate sheathed heating element (6) is attached directly to the underside of the base plate (4). A heat diffusion member (10) is in good thermal contact with the base plate (4) and in good thermal contact with and arranged to extend only part way around a side wall of the element sheath (6). The heat diffusion member (10) further defines at least one region (12) for receiving a thermal sensor for detecting overheating of the element (6).
