Accordingly, the raw water along the first vertical flow path 35a passes through the inlet 43a of the filter housing cap 43 of the filter cartridge 40 coupled to the lower portion of the connector 30 and follows the inflow path 43b. Flows into the filter cartridge 40. Then, it passes through the water inlet 42a of the filter upper cap 42 and flows into the filter housing 41 and is purified by the filter.

Then, the purified water is moved to the hollow tube 45 through the filter lower cap 44, the hollow tube 45 is in communication with the purified water passage 42b of the filter upper cap 42 is purified water It is moved to the discharge passage 43c of the filter housing cap 43 communicated therethrough, and then to the second vertical passage 35b of the connector body 32.

At this time, the second flow path blocking member 37 for opening and closing the second vertical flow path 35b is also opened in the same manner as the second flow path blocking member 36, and the purified water is in communication with the second vertical flow path 35b. Pass through the second horizontal flow path (34b), and through the inner horizontal and vertical flow paths (22a, 22b) of the second connection member 20 coupled to the other coupling groove (32a) and the second connection member It is conveyed to the outside through the purified water discharge port 21b of the coupling plate 21 of (20).

Meanwhile, the filter housing 40 and the member inserting portions 15 and 25 of the filter cartridge 40, the first connecting member 10, and the second connecting member 20 are attached to the connector 30 on the outer circumferential surface thereof. O-ring (2) is installed to prevent leakage of raw or purified water.

In addition, the O-ring is also provided on the outer circumferential surface of the valve body 13b of the raw water locking valve 13 coupled to the first connecting member 10 and the body 14c, 36c, 37c of the flow path blocking members 14, 36, 37. (O-ring, 2) is installed to prevent leakage of raw or purified water.

6 is a partial cross-sectional perspective view showing a state in which the filter assembly having a rotary connector according to the present invention is applied in multiple stages.

As shown, in the filtering means of the water purifier, the filter cartridge 40 is provided with a multi-stage filter cartridge 40 in order to maximize the water purification effect according to the type of filter inherent therein.

At this time, preferably each filter cartridge 40 is a sediment filter to remove the foreign matter of the macro-sized, precarbon filter to remove residual chlorine components and organic chemicals in the water by using the adsorption method of activated carbon (pre -Carbon filter), Reverse osmosis filter (R / O) that processes various pollutants, bacteria, inorganic substances, heavy metals, etc. in the water by using fine pores, water odor and gas components in water treatment An improved post-carbon filter is installed with four different filter cartridges 40 with a filter cartridge 40 installed therein.

In addition, each filter cartridge 40 includes an intermediate connecting member 50 connected to the connector 30 of the neighboring filter cartridge 40 so that water passing through the neighboring filter cartridge 40 can be introduced. It is configured by.

In this case, the plurality of pivotal connectors 30 to which the filter cartridge 40 is coupled are installed such that the coupling grooves 32a and the coupling grooves of the neighboring rotational connector 30 face each other, and the intermediate connection member 50 is disposed. The first coupling member 10 and the second coupling member 20 has a structure similar to that of the coupling groove and the coupling groove facing each other is configured to be a hinge axis of the connector 30 and the connector.

To this end, the intermediate connecting member 50 is a coupling plate 51 fixed to one side of the water purifier, horizontally connecting the connector 30 and the connector 30 neighboring therein integrally with the coupling plate 51. It consists of the body 52 in which the flow path 52b was formed.

At this time, the coupling plate 51 is fixed to the inner bracket of the water purifier in a plate shape in which a plurality of coupling holes 51a are formed in all directions.

In addition, the body 52 is preferably “ㅗ” shaped and integrally formed with the coupling plate 51.
