Abstract

A liquid heating vessel (6) has a heated base (8) and a thermally sensitive control mounted to the base (8). The control comprises a boiling control for interrupting the supply of energy to the vessel element (12) when liquid in the vessel boils. It is responsive to the liquid temperature in a sump (18) in the vessel base, and comprises a bimetallic actuator (100) in thermal contact with the sump (18) through a C-shaped copper conductor member (110). The vessel also comprises a simmer control operable to maintain the liquid in the vessel at a predetermined temperature after boiling. This control comprises a snap-acting bimetallic actuator through which the current to the element flows in rapidly heat the actuator after 3 set of contacts is closed, so as to supply energy to the element in short bursts to prevent an audible heating sound.
