Claims7
A distilled water production device comprising:
- a boiler for producing steam,
- a condenser for condensing the steam supplied from said boiler by means of cooling water,
- means for supplying the cooling water to said condenser,
- an outflow path for the cooling water connected to said condenser,
- an overflow tube provided along said outflow path and divided into an upper chamber and a lower chamber by a flow dividing plate, said upper chamber receiving cooling water from said outflow path,
- means for discharging excess cooling water from inside of said upper chamber comprising a pipe passing through said dividing plate from said upper chamber to said lower chamber and communicating between said upper chamber and said lower chamber so as to keep the height of the cooling water retained in said upper chamber constant,
- said flow dividing plate being formed with at least one hole through which the cooling water falls from said upper chamber into said lower chamber at a predetermined rate of flow, and
- means for supplying cooling water to said boiler from said lower chamber.
