Water filter assembly and refrigerator and water purifier having the same

摘要

A water filter assembly, and a refrigerator and a water purifier having the same, including: a manifold having a inflow path through which raw water flows in and an outflow path through which filtered water flows out; a case supporting the manifold; and a filter cartridge coupled to a lower side of the case such that it is separable and connected with the outflow port of the manifold, wherein a fluid flow control unit is installed between the manifold and the filter cartridge and rotates according to a rotation of the filter cartridge, the center of the rotation is the same as the center of an outlet of the filter cartridge, and the fluid flow control unit includes a disk having a connection hole allowing the raw water inflow path and an inlet of the filter cartridge to communicate only at a certain position.

1. A water filter assembly comprising:
a manifold having an inflow path through which raw water flows in, an outflow path through which filtered water flows out, an inflow port formed on the inflow path, and an outflow port formed on the outflow path; a case supporting the manifold; a filter cartridge configured to be coupled to a lower side of the case such that the filter is separable and connectable with the outflow port of the manifold; and a fluid flow control unit installed between the manifold and the filter cartridge, the fluid flow control unit being configured to rotate according to a rotation of the filter cartridge such that the center of rotation of the fluid flow control unit is the same as the center of an outlet of the filter cartridge, the fluid flow control unit including a disk rotatably installed on the manifold and having a connection hole which connects the inflow port and an inlet of the filter cartridge only at a certain rotational position, wherein an upper face of the disk includes a prominence formed to press against a lower surface of a sealing member assembled to the inflow port of the manifold to completely close the inflow port upon rotation of the disk about the center of rotation when the filter cartridge is detached from the manifold, and wherein the sealing member has a tubular, cylindrical shape the inflow port, the lower surface of the sealing member extends below an opening of the inflow port, such that the prominence presses against the lower surface of the sealing member but not against the inflow port, and the lower surface of the sealing member has a notch.
