Abstract
Water purification is performed in a simplified manner within a vessel having at least the lower porton thereof filled with a filtration media such as activated carbon. A spout is provided near the upper end. A filter media placed in the spout. The top of the vessel is closed with a cap which is vented to permit the escape of matter which is vaporized during the heating phase. The vessel preferably has a handle to aid in the dispensing of the purified water. The vessel is preferably formed of a material which is safe for use in microwave heating devices. A valve may be provided at the bottom of the vessel for dispensing purified water directly into a container such as a cooking vessel or beverage maker. In another embodiment the liquid is purified as it rises through the carbon in the container.
Claims16
Apparatus for purifying a liquid comprising:
- a container having a spout and an open top for introducing a liquid into the container;
- a filter positioned to remove particulate matter from the liquid as the liquid containing such particulate matter passes through the spout;
- a predetermined quantity of carbon positioned in said container;
- said container being formed of a material capable of withstanding heat sufficient to raise the temperature of the contents which are caused to interact with the carbon during heating;
- the bottom of the container being provided with an opening;
- manually operable valve means positioned to seal said bottom opening and movable between an open and closed position for selectively dispensing the contents of the container through said bottom opening;
- said filter substantially covering the opening in the bottom of the container;
- a second liquid receiving container having an open upper end and a lid surrounding said open upper end for supporting the first mentioned container for collecting the contents of said first mentioned container when its valve means is operated to the open position.
Apparatus for purifying a liquid comprising a container having a pouring spout and an open top for introducing a liquid into the container;
- an inlet opening being provided in said container near the bottom thereof for introducing liquid into said container whereby the liquid delivered to said container rises in the container so that the surface of said liquid reaches the level of said spout whereupon the liquid is delivered from said spout;
- first filter means positioned over the inlet opening of said container through which liquid is introduced to filter particulate matter therefrom;
- a carbon filter medium being placed in said container to coact with and adsorb matter from the heated liquid passing through the container;
- second filter means positioned over said spout for filtering particulate matter from the liquid as it passes through said spout;
- heater means arranged within said container a predetermined distance above the bottom thereof for heating liquid as it rises in said container whereby the liquid is gradually heated to provide a temperature gradient through said container which ranges between the temperature level of the liquid introduced into the inlet opening to the boiling point of the liquid at the surface thereof;
- said boiling point being reached by introducing liquid into the container at a predetermined flow rate.
