<p>PURPOSE: To simply start the reuse of a water feed unit even after it is not used for a long time by surrounding a Peltier array in a sandwich-like manner between a heat-exchanger which allows hot water to pass therethrough and a heat-storageable heat-exchanger which allows water to pass therethrough. CONSTITUTION: In an electrically controlled water feed unit 12 having a Peltier array 60, a heat-exchanger 30 which allows hot water 30a to pass therethrough and a heat-exchanger 32 which allow water 32a to pass therethrough, are arranged within a thermally connectable range. Further, the heat-exchanger 30 which allows hot water 30a to pass therethrough is heat-storageable since it is provided with a battery or a condenser. Further, both heat-exchangers 30, 32 are separated from each other, the Pertier array 60 being interposed therebetween in a sandwich-like manner. With this arrangement, the temperature raised up on the hot side of the Pertier array 60 is held for a long time, thereby it is possible to eliminate hindrance to the reuse of the water feed unit 12.</p> |
