Abstract
There is disclosed a water discharge device that has a water flow path that extends from an inlet through an outlet chamber to an outlet spout; a valve assembly for opening and closing the water flow path; a heating element for heating the outlet chamber and spout to evaporate moisture on internal surfaces of the outlet chamber and spout when the flow path is closed by the valve assembly, the heating element being remote from the flow path; and a controller for controlling operation of the valve assembly and the heating element, the controller including a switch that is operated directly or indirectly by a user to control the opening of the water flow path.
Claims15
A water discharge device comprising:
- a valve body that defines a water flow path extending from an inlet to an outlet spout, an inlet chamber in which a valve seat and a valve plunger that co-operates with the valve seat is located, and a valve plunger that co-operates with the valve seat and is movable by a valve actuator to open and close the flow path;
- a valve assembly for opening and closing the water flow path, the assembly being located at a top of the flow path so that, when the flow path is closed by the valve assembly, water downstream of the valve assembly drains from the flow path, the valve assembly including the valve actuator;
- a heating element for heating an outlet chamber and the outlet spout to evaporate moisture on internal surfaces of the outlet chamber and spout when the flow path is closed by the valve assembly, the heating element being remote from the flow path;
- and
- a controller for controlling operation of the valve actuator, the controller including a switch that is operated directly or indirectly by a user to control the opening of the water flow path;
- wherein the valve body includes a void that extends around the inlet chamber for minimizing conductive heat transfer from the heating element to the inlet chamber.

A water discharge device comprising:
- a valve body that defines a water flow path that extends from an inlet to an outlet forming an inlet chamber there between;
- a valve seat and a valve plunger that co-operates with the valve seat and is movable by the valve actuator to open and close the flow path between the inlet and outlet;
- a heating element that is remote from the flow path, the heating element being arranged to heat the device to evaporate moisture on internal surfaces surrounding the flow path between the valve assembly and the outlet when the flow path is closed by the valve assembly;
- and
- a controller for controlling operation of the valve assembly, the controller including a switch that is operated directly or indirectly by a user to control opening and closing of the water flow path;
- wherein the valve body includes a void that extends around the inlet chamber for minimizing conductive heat transfer from the heating element to the inlet chamber.

- and
- a controller for controlling operation of the valve assembly and the heating element, the controller including a switch that is operated directly or indirectly by a user to control the opening of the water flow path;
- wherein the valve body has an inlet chamber that forms part of the flow path;
- wherein the valve seat and valve plunger are positioned between the inlet and outlet chambers;
- and wherein the valve body includes an aperture within which the heating element is disposed, the aperture being beside the outlet chamber, to maximize conductive heat transfer to the outlet chamber and outlet spout, the valve body includes a void in the form of an annular recess that extends around the inlet chamber for minimizing conductive heat transfer from the heating element to the inlet chamber.
