Claim:
Device for cooling hot water to a drinking temperature for preparing a meal for a baby or small child comprising: a cooling system containing a coolant, said coolant being water, with a cooling line extending through the coolant and having an inflow on an inflow side for letting in hot water and an outflow on an outflow side for cooled water; wherein the cooling system has a closure through which the coolant is introduced into the cooling system; a least one filling vessel with defined fill volume for receiving the water to be cooled and an opening; the filling vessel being connectable at the opening to the inflow side of the cooling system, the opening of the filling vessel being closed by the connection to the cooling system; the filling vessel opening and the inflow side of cooling system each further comprises complementarily cooperating connection elements such that the filling vessel and the cooling system form a virtual unit; a venting opening, said venting being a notch piercing the connection elements of the inflow end of the cooling system, is disposed at the interface between the cooling system and the filling vessel for introducing ambient air into the emptying filling vessel such that after inverting the virtual unit by 180° for initiating the cooling process the introduced air becomes heated during the percolation through the hot water; wherein as a function of the defined quantity of hot water flowing from the filling vessel into the inflow of the cooling system and of the temperature and of the quantity of coolant contained in the cooling system the hot water flows from the outflow of the cooling system at a temperature specified within narrow limits; at least one collection vessel for collecting the cooled water, said collection vessel being connectable to the outlaw end of the cooling system and wherein at the outflow end of the cooling system further comprises connection means for connecting the collection vessel; wherein the cooling system further comprises an inner thread section at its inflow end and the at least one filling vessel comprises a corresponding outer thread section; a venting opening disposed at the interface between the cooling system and the collection vessel.
