FIG. 2 is a schematic cross-sectional view of a water purifier in which a purified water backflow prevention valve is installed. 2 and 3 are sectional views of the drain valve, respectively, and FIG. 3 shows the rubber valve 1 being deformed by pressure due to water pressure. FIG. 4 is a plan view of a rubber valve having a notch in the periphery, and FIG. 5 is a sectional view taken along line AA' in FIG.
FIG. 6 is a plan view of a rubber valve with holes;
The figure is a sectional view taken along line BB' in FIG. Figure 8 is the first
FIG. 2 is a schematic sectional view, with some parts missing, of a water purifier in which the water drain valve shown in the figure is installed on the side of the water purifier body and below the hollow fiber membrane layer instead of being installed at the bottom of the water purifier body. Figure 9 is a schematic cross-sectional view, with some parts missing, of a water purifier in which a water drain valve made of a metal spring and a ball valve is installed at the bottom of the water purifier body instead of the water drain valve made of a rubber valve in Figure 1. be. FIG. 10 shows a water purifier in which a hollow fiber membrane layer 49 is in the center and an adsorbent layer 48 is arranged approximately concentrically on the outside thereof, with an air inlet and an inlet for the hollow fiber membrane layer and an air inlet and an outlet for the adsorbent layer.
