Assume

When the user rotates the second cover 300 to the position as shown in FIG. 8A using the handle 350, the rotation position detecting stopper 330 detects a plurality of rotation positions as shown in FIG. It is stopped in the rotation position detecting groove 240 formed in the center of the groove 240. As shown in FIG. 8A, the second position sensing member 530 positioned at the center of the plurality of second position sensing members 530 senses the first position sensing member 520. The second position sensing member 530 that detects the first position sensing member 520 sends a signal to the controller 600 shown in FIG. 7. The control unit 600 opens the on / off valve V provided in the pipe through which carbonated water flows among the plurality of on / off valves V. Accordingly, as shown in FIG. 8A, the carbonated water is supplied to the user through the fluid inlet pipe 410, the fluid outlet pipe 420, and the outlet pipe protection tube 310 formed in the center of the fluid flow part 400 as shown in the drawing. do. At this time, the light emitting member 340 emits red light and the user can know that carbonated water is discharged through the light emitting member 340.

In addition, when the user rotates the second cover 300 to the position as shown in FIG. 8B by using the handle 350, the rotation position detecting stopper 330 may be moved out of the plurality of rotation position detection grooves 240. As shown in the figure shown in Figure 3 is stopped in the rotation position detection groove 240 formed on the right. As illustrated in FIG. 8B, the second position sensing member 530 positioned at the top of the plurality of second position sensing members 530 senses the first position sensing member 520. The second position detecting member 530 which detects the first position detecting member 520 sends a signal to the control unit 600 shown in FIG. 7, and the control unit 600 has a constant flow of the plurality of open / close valves V. FIG. Open the valve (V) provided in the pipe. Accordingly, as shown in FIG. 8B, the purified water is supplied to the user through the fluid inlet pipe 410, the fluid outlet pipe 420, and the outlet pipe protection tube 310 formed on the right side of the fluid flow part 400 as shown in the drawing. do. In this case, the light emitting member 340 emits green light, and the user may know that the purified water is discharged through the light emitting member 340.

When the user rotates the second cover 300 to the position as shown in FIG. 8C by using the handle 350, the rotation position detecting stopper 330 may be rotated among the plurality of rotation position detection grooves 240.
