The water transfer siphon has a siphon inlet aperture in communication with the water receiving chamber, and a siphon outlet aperture in communication with the water heating chamber. The water transfer siphon is preventable from priming with water from the water receiving chamber through a first rotation of the kettle to increase an elevation of a siphon crest of the water transfer siphon relative to a water level within the water receiving chamber, the first rotation occurring in a first direction. ## Claims ### Claim 1 A kettle, comprising: a water receiving chamber; a water heating chamber; and a water transfer siphon, the water transfer siphon having a siphon inlet aperture in communication with the water receiving chamber, and a siphon outlet aperture in communication with the water heating chamber, wherein the water transfer siphon is preventable from priming with water from the water receiving chamber through a first rotation of the kettle to increase an elevation of a siphon crest of the water transfer siphon relative to a water level within the water receiving chamber, the first rotation occurring in a first direction. ### Claim 2 (depends on 1) The kettle as claimed in claim 1, wherein the water transfer siphon is primeable with water from the water receiving chamber through a second rotation of the kettle to decrease the elevation of the siphon crest of the water transfer siphon relative to the water level within the water receiving chamber, the second rotation occurring in a second direction. ### Claim 3 (depends on 2) The kettle as claimed in claim 2, wherein the first direction is a rotation about a substantially horizontal axis towards a spout of the kettle and the second direction is a rotation about a substantially horizontal axis away from the spout and towards a handle of the kettle. ### Claim 4 (depends on 1) The kettle as claimed in claim 1, wherein the water receiving chamber further comprises a water receiving chamber bleed aperture formed within the lowermost portions of the water receiving chamber, the water receiving chamber bleed aperture communicating the water receiving chamber to the water heating chamber and being of a lower water transfer rate capacity than the water transfer siphon. ### Claim 5 (depends on 4) The kettle as claimed in claim 4, wherein the water receiving chamber bleed aperture feeds directly into a vertically elongate slot, or is partly formed by a vertically elongate slot. ### Claim 6 (depends on 4) The kettle as claimed in claim 4, wherein the smallest cross sectional area of the water receiving chamber bleed aperture does not exceed substantially 4 square millimetres. ### Claim at position 7 7-8. (canceled) ### Claim 9 (depends on 1) The kettle as claimed in claim 1, wherein the water transfer siphon is preventable from priming for a desired quantity of water within the water receiving chamber of the kettle through a mechanical means for temporarily and substantially obstructing a portion of the water transfer siphon. ### Claim 10 (depends on 9) The kettle as claimed in claim 9, wherein the mechanical means for temporarily and substantially obstructing a portion of the water transfer siphon comprises a gate disposed proximal the siphon inlet aperture or the siphon outlet aperture, the gate being movable by user actuation between an open position allowing flow through the siphon inlet aperture and the siphon outlet aperture and a closed position substantially blocking flow through the siphon inlet aperture and the siphon outlet aperture. ### Claim 11 (depends on 9) The kettle as claimed in claim 9, wherein the mechanical means for temporarily and substantially obstructing a portion of the water transfer siphon comprises a valve arranged proximal to the siphon inlet aperture or the siphon outlet aperture, the valve selectively blocking or unblocking the siphon inlet aperture or the siphon outlet aperture, and the valve rotates between an open position allowing flow through the siphon inlet aperture and the siphon outlet aperture and a closed position substantially preventing flow through the siphon outlet aperture, the valve being movable from the open position to the closed position through rotation of the kettle in the first direction. ### Claim 12 (canceled) ### Claim 13 (depends on 1) The kettle as claimed in claim 1, wherein the water receiving chamber further comprises water level markings arranged to measure a water level within the water receiving chamber for the kettle whilst not vertical and at a water charging angle at the time. ### Claim 14 (depends on 1) The kettle as claimed in claim 1, wherein the water receiving chamber is upwardly open except for a coverage provided by a splash guard, and the portion of the water receiving chamber not covered by the splash guard forms a water charging aperture through which the water receiving chamber may be charged with water. ### Claim 15 (depends on 14) The kettle as claimed in claim 14, wherein the splash guard is arranged to cover those portions proximal to a handle of the kettle, but not to cover those portions proximal to a spout of the kettle. ### Claim 16 (depends on 15) The kettle as claimed in claim 15, wherein a portion of the water transfer siphon is formed within the splash guard. ### Claim 17 (canceled) ### Claim 18 (depends on 14) The kettle as claimed in claim 14, wherein at least a portion of the splash guard is formed of a substantially transparent or translucent material. ### Claim 19 (depends on 14) The kettle as claimed in claim 14, wherein the splash guard is detachable from the water receiving chamber. ### Claim 20 (depends on 14) The kettle as claimed in claim 14, wherein the splash guard further comprises a flap pivotally attached to the splash guard and arranged to selectively allow coverage of the water charging aperture. ### Claim 21 (depends on 1) The kettle as claimed in claim 1, wherein the water transfer siphon includes an assembly of a siphon inner pipe and a siphon outer pipe concentric with the siphon inner pipe, a gap between the siphon inner pipe and the siphon outer pipe forms a siphon upwards channel, and a passage through the siphon inner pipe forms a siphon downwards channel. ### Claim 22 (canceled) ### Claim 23 (depends on 1) The kettle as claimed in claim 1, further comprising a detachable power supply base. ### Claim 24 (depends on 23) The kettle as claimed in claim 23, wherein the water receiving chamber includes a light source adapted to illuminate at least part of the interior of the water receiving chamber, the light source being automatically switchable between an on state when the kettle is separated from the detachable power supply base, and an off state when the kettle is located on the detachable power supply base ### Claim at position 24 25-27. (canceled) ### Claim 28 (depends on 13) The kettle as claimed in claim 13, wherein the water charging angle is an angle between substantially 15 degrees and substantially 30 degrees. ### Claim at position 26 29-30. (canceled)
