PURPOSE:To prevent that carbonated water is diluted with the water remaining in piping by a method wherein a carbonated water taking-out pipe is branched to be allowed to communicate with the air part in an apparatus main body and a carbonated water cut-off solenoid valve is closed at the same time when the use of carbonated water is completed and opened only for a definite time by a timer. CONSTITUTION:The throttling device 17 and carbonated water taking-out port 6 provided to a carbonated water making apparatus main body 1 communicate each other through the branch part 5 where a solenoid valve 4 and piping are branched in two directions using a communication pipe 3. The branch part 5 is provided immediately behind the solenoid valve 4 to be allowed to communicate with the air part A in the container 10 of the apparatus main body 1 through a carbonated gas cut-off solenoid valve 7. The carbonated gas cut-off solenoid valve 7 is opened only for a definite time by the control of a timer immediately after the use of carbonated water is completed and the one-way solenoid valve 4 is closed. By this constitution, since the carbonated water remaining in piping is pushed out to the outside by carbon dioxide after carbonated water is used, it is prevented that the concn. of carbonated water is diluted with the water remaining in piping. |
