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 coil-type 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 siphon tube also extending through the cover. An improved running thermostat, sensing tube and mounting system is provided for sensing temperature variations in a range of less than 6.degree. F. whereby to be quickly responsive to temperature changes and thereby activate and de-activate the heating element, which is arranged in electric communication therewith. The improved running thermostat system includes a thin, elongate generally self-supporting sensing tube having a diameter no greater than about 0.30 inches and extending freely substantially the full height of the interior of the hot water container and being removably mounted through the cover of the hot water container by a mounting collar at the upper end of the sensing tube seated in a fitting on the cover and connected to the thermostat by a capillary tube. The improved running thermostat system may be removed from the cover as a unit in order to expedite maintenance, replacement or repair.
