Abstract
Abstract Apparatus for preparing hot beverages particularly tea comprises a water container having a water heater and a water discharge conduit. Below the container is a strainer device for holding a supply of beverage solids and below this strainer is a receiver for the finished beverage. An automatically controlled deflector is provided for directing heated water from the water conduit firstly into the strainer to mix with the solids and filter into the beverage receptacle. After a certain time the deflector automatically is moved to direct the supply of heated water straight into the receptacle. Control of the deflector is either by way of a float in the beverage receptacle or by way of a timing mechanism.
