ABSTRACT:
A chilling chamber (10) connected to a water reservoir (12) or to a pipe (29) within which water flows has a thermally conductive probe (16) which is connected to the cold side of a thermoelectric device (18), the hot side being connected to a heat sink (20). A tube (30) is coiled about the probe and has one end (28) connected with the water in the storage reservoir or pipe and another end (32) connected to a faucet (34). Water as a heat transfer medium (36) is stored within the chilling chamber (10) about the probe (16) and the coil of tubing (30). The probe cools the heat transfer medium which cools the water within the coil of tubing. A check valve (42) releases air in the chamber compressed as an ice ball forms about the probe. Cold water thus flows out the faucet when the faucet is opened for a short time and the water within the coil gradually raises in temperature to again be cooled by the heat transfer medium.
