Apparatus for heating liquids with steam sensor and multiple steam passages
First Claim
1. An apparatus for heating liquids comprising a hollow body defining a receptacle for liquid to be heated, a heating element for heating liquid within the receptacle, a spout for enabling liquid to be poured into or out of the receptacle, a control chamber containing a control device carrying a steam sensor and being responsive to the steam sensor to control operation of the heating element, a steam outlet provided in an upper part of the receptacle in a location remote from said spout and a steam passage arrangement provided between the steam outlet and the steam sensor, the steam passage arrangement comprising a first steam passage separate from the spout and communicating with and extending downwardly from the steam outlet of the receptacle to an outlet positioned away from the control device and a second steam passage branching from the first steam passage at a branching location below the steam outlet of the receptacle and extending to a location higher than the branching location, the steam sensor being provided adjacent a steam aperture within the second steam passage above the branching location.

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).

- 2. An apparatus for heating liquids comprising a hollow body defining a receptacle for liquid to be heated, an electrical resistance heating element for heating liquid within the receptacle, a control chamber containing a control device carrying a steam sensor and being responsive to the steam sensor to control operation of the heating element and a steam passage arrangement provided between a steam outlet provided in an upper part of the receptacle and the steam sensor, the steam passage arrangement comprising a channel-defining member defining at least one open channel communicating with the steam outlet of the receptacle, and a cover member formed separately from the channel-defining member and covering the at least one open channel thereby defining with the channel-defining member at least one passage for steam, a member selected from the group of (a) the channel-defining member and (b) the cover member providing a coupling aperture by means of which the control device is mounted and electrically coupled to the heating element and the other member selected from the group of the channel-defining member and the cover member being provided with a steam aperture to enable steam within the at least one passage to reach the steam sensor.
