Abstract
The hot water container of a beverage making device is provided with a removable cover sealed thereto and has arranged therein an electric immersion heating element controlled by a running thermostat and a safety thermostat for heating a volume of cold water admitted into the container through an inlet tube extending through the cover and controlled by a timed inlet valve, the hot water being discharged from the container at a brewing station through a syphon tube also extending through the cover. A tap-off hot water system for providing hot water continuously at a temperature substantially the same as the brewing water is provided by a continuous helical water heating coil residing within the upper half of the container above the heating element and having a water receiving tube extending upwardly from the bottom of the coil to a fitting on the cover connected to the source of water upstream of the inlet valve and a water outlet tube extending upwardly from the top of the coil to a second fitting on the cover connected to a discharge pipe communicating with a manually operable water faucet at the exterior of the beverage-making device for selectively supplying hot water for making soup, tea, hot cocoa, etc. The hot water system is provided with check valve establishing a minimum pressure for admission of water into the coil and an adjustable speed valve for varying the discharge water pressure at the faucet.
