Abstract
Abstract A hot water supply apparatus such as for use in a coffee brewer wherein cold water is poured into the top of the apparatus to displace hot water from a heating tank therein and cause delivery of the displaced hot water to a brewing cartridge wherein the coffee is brewed and then delivered to a suitable receptacle, such as a decanter. The means for conducting the poured cold water into the heating tank includes a basin within an outer housing of the apparatus. The basin is provided with a lid which further closes the open top of the housing. The lid is provided with a duct member having a selectively positionable cover permitting the user to pour cold water into the basin without removing the lid. However, when servicing of the apparatus through the open top of the housing is desired, the entire lid may be readily removed.
