ABSTRACT:
An improved beverage-making device, particularly useful for brewing coffee, provides a safety thermostat arrangement for quickly detecting excessive temperatures of a hot water container generally near a heating element arranged therein. A running thermostat provides a self-supporting sensing tube means in cooperation with a capillary tube and thermostat which detect the mean temperature of the hot water and are responsive to a narrow range of temperature variations within the hot water container. The improvement further includes a tap-off hot water system which provides hot water separately and independently of the brewing water heated in said container. The system is connected upstream of the cold water inlet valve of the device and directs cold water into a water coil means residing within the hot water container. Outlet pipe means convey heated water from the coil to an outlet faucet projecting exteriorly of the device. An improved spray disk assembly provides a cooperatively lockable spray disk and mounting collar. The spray disk locks with the mounting collar to tightly seal a flexible gasket around said spray disk whereby the spray disk receives hot water siphoned from said hot water container and evenly distributes hot water in a random dripping flow through the disk. Additionally, a bottom drain system is provided for emptying the hot water container which is non-corrodible and thread disengageable from said container. The drain system provides means for tightly sealing around a bottom drain hole of the container and manually operable valve means to facilitate draining the container.
