摘要： A filter (10) for use in a water heating vessel, such as an electric kettle, to filter sedimentary material in the water includes a scale collector (25), for example in the form of a compacted mesh block, carried on the filter. The block can be supported by a carrier member (27) permanently or detachably mounted on the filter frame, preferably towards an end of the filter closest to the bottom of the vessel.

摘要： 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).

摘要： A water cleaning device (1) is provided which has a housing (10) arranged to be supported by a surface, for example stood upon a work surface (50). The housing (10) defines a receptacle (2) for water (100) to be cleaned. A water filtration unit (20) is mounted to the housing (10) and has an outlet (21) for filtered water (101). An electrically operated pump (30) and control means (16,17,25,26,27,28,40) for controlling the pump (30) are provided within the housing (1) for pumping water through the filtration unit (20) to provide cleaned filtered water (101) at the outlet (21). The filtration unit (20) carries a collar (29) which, when the filtration unit (20) is removed from its mounting support (12), is fixed in position relative to the filtration unit (20) so that the filtration unit (20) cannot be mounted to the mounting support (12) again after the filtration unit (20) has once been removed from the housing. This prevents accidental re-use of an old filtration unit which is clogged or otherwise not fully operational.
