Until the water injection stop command signal is sent, continuous water injection is performed by the continuous water injection means 75. Therefore, it is possible to obtain purified water of any water injection amount at any time.

  When the water injection is finished, as shown in FIGS. 1 to 7, the water injection pipe 30 is rotated to be positioned at a predetermined stop position X, and the water injection port 31 is connected to the connection port 40. Since it is a simple operation that only rotates the water injection pipe 30, the operability is improved. In this case, the lock member 48a of the lock mechanism 48 is released while being pressed by hand or the tip of the tip member 30b, and the water injection port 31 is inserted into the connecting port 40, and then the lock member 48a is inserted into the spring 48b. It is advanced by the urging force and positioned at the lock position. When the water injection port 31 is inserted into the connection port 40, the connection port 40 can be finely moved by the floating support portion 44. Therefore, the water injection port 31 can be easily aligned with the connection port 40 and can be easily inserted. The operability is improved.

  When the water injection pipe 30 is positioned at the stop position X, the detector 49 comprising a limit switch detects that the water injection pipe 30 has reached the stop position X, so that the control unit 70 intermittently after a predetermined time has elapsed. The pump 4 is driven for a predetermined time to circulate the water in the water injection line 10 and the return line 32. This intermittent circulation is repeated until the water injection pipe 30 is separated from the stop position X and the detector 49 detects this. Thereby, the heating by the continuous driving | operation of the pump 4 can be prevented and labor saving can be achieved. Moreover, since the water of the water injection line 10 and the return line 32 is circulated, since the purification module is of a reverse osmosis membrane (RO membrane) type, there is a concern about the reverse flow of purified water, but there is also an effect of preventing this. .

During the stop of water injection, the first water injection side antibacterial means A1 functions, that is, the water injection port 31 is connected to the connection port 40, so that fungi such as virus bacteria, bacteria, fungi and the like try to enter.

Further, it can be sterilized by simple means.

  Next, when obtaining purified water, similarly to the above, the water injection amount is appropriately set on the operation panel 60, the lock mechanism 48 is unlocked, and the water injection pipe 30 is moved from the stop position X to an appropriate rotation position. The water injection start button 61 is pushed. Thereby, the pump 4 is driven, purified water is sent out from the water treatment unit F having the purification module, and is injected from the water injection port 11 through the water injection conduit 10. In this case, since the first water injection side antibacterial means A1, the second water injection side antibacterial means A2 and the first drainage side antibacterial means B1 function while the water injection is stopped, water is injected from the water injection port 11. The situation where fungi are mixed into the purified water is prevented, contamination of the purified water is surely prevented, and safety is improved.
