Abstract
A vessel or kettle for holding water has a first chamber from which water can be pumped though a filter into a second chamber. The pump can be gravity, manual or power operated. Cold water from the first chamber can be pumped though an annular filter of ion exchange resins into the second chamber where it can be heated. The contents of filter can be held in a replaceable porous bag. A meter can indicate the amount transferred, eg in multiples of a volume such as a cupful. The vessel can have a spout valve that selectively allows the first chamber to be filled or water to be poured from the second chamber. The first chamber and/or the pump can be external to the vessel. The pump can include non-return valves and a siphon system.
Claims23
A filtered-water dispenser comprising first and second tanks connected via a filter, a positive displacement pump manually-operative to transfer a controlled volume of the contents of the first tank through the filter to the second tank, the pump having a working volume within the first tank defined by a piston situated in a cylinder, a seal providing contact between the piston and the cylinder, and two valves for allowing water to flow in a determined way in and out of the pump, and an electric heating element associated with the second tank that can be switched on to boil the water in said second tank.
