Title:
ELECTRICAL WATER HEATING APPLIANCES
Document Type and Number:
WIPO Patent Application WO/2012/114092
Kind Code:
A3
Abstract:
An electrical water heating appliance comprises pump means (4) connected to a water heating means (16) via a water flow path (14). One or more flow-regulating valve means (18,20) are arranged in the flow path (14) to regulate the flow of water to the heating means (16) so as to achieve a substantially uniform flow rate. The flow-regulating valve means may include a pressure-compensating valve means 10 (18) arranged to achieve a substantially uniform flow rate regardless of the water pressure. A suitable pressure-compensating valve (18) means may comprise an elastic diaphragm arranged to regulate the flow by distorting in response to the pressure of water entering the valve means. The water heating means (16) may be a water boiler for steam generation.
