ABSTRACT:
A hollow body (2) defines a receptacle (3) for liquid to be heated. A heating element (4) for heating liquid within the receptacle (3) is controlled by a control device (6) located in a control chamber (5). The control device (6) carries and is responsive to a steam sensor (7). A steam passage arrangement (10) defines first and second steam passages (120 and 130). The first steam passage (120) communicates with and extends downwardly from the steam outlet (3a) of the receptacle (3) to an outlet (5a) positioned away from the control device (6). The second steam passage (130) branches from the first steam passage (120) at a branching location (14) below the steam outlet (3a) of the receptacle (3) and extends to a location (13a) higher than the branching location (14), the steam sensor (7) being provided adjacent a steam aperture (15a) within the second steam passage (130) above the branching location (14).
