Abstract
A beverage maker includes a continuous flow electric heater assembly of tubular construction adapted to be connected to a source of fresh water and is arranged for guiding fresh water therethrough for heating the fresh water to brewing temperatures, and a filtering vessel and pipe arrangement to introduce heated fresh water from the heater assembly to the filtering vessel. The heater assembly comprises at least two tubular continuous flow electric heaters each being bent into a U-shaped configuration. The heaters are arranged in a generally horizontally juxtaposed mutually nested relationship and each has a metal heater tube containing an electric heating element, a metal water pipe extending adjacent the metal heater tube parallel therewith and a heat conducting flat web connecting the heater tube with the water pipe for transferring heat from the heater tube to the water pipe. There is further provided a tubular connector coupling the water pipes of the heater assemblies to one another.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
