Abstract
A liquid heating appliance includes a container defining a liquid heating compartment, a lid for covering the container, and a heater for heating liquid within the compartment. The lid defines a recessed receiving chamber for receiving a volume of liquid, and the receiving chamber includes a non-return filling valve. In a filling mode of the appliance, the filling valve allows liquid to flow from the receiving chamber into the liquid heating compartment. In a heating mode of the appliance, the filling valve prevents fluid from flowing from the liquid heating compartment into the receiving chamber.
