ABSTRACT:
Apparatus for reducing the escape of water vapor from a heated water reservoir tank of a coffee machine to prevent drop in the water level by evaporation particularly during long periods of non-use. The machine has an outlet fitting leading to use from a point adjacent the top of the tank and a water inlet stand-pipe leading to the bottom of the tank to introduce displacement water into the tank. A looped tube leads from the top of the tank to the stand-pipe and in spaced relation thereto. Water vapor moves into the looped tube and is reintroduced to the tank by the stand-pipe to reduce depletion. The looped tube also constitutes a vacuum break for the sealed tank to allow entry and exit of displacement water. A baffle wall extends downwardly from the top of the tank into the water and surrounds the outlet fitting so that water vapor cannot escape via the outlet fitting.
