Abstract

Disclosed herein is a refrigerator. In the refrigerator, a water purifying unit including a filter unit to purify water supplied from a water supply source is arranged adjacent to a drawer type storage container in an otherwise useless space of a storage compartment.

First claim

What is claimed is:

1. A refrigerator, comprising:
a water tank having an inlet for receiving water into the water tank and an outlet for discharging water from the water tank, the inlet and the outlet disposed at a first longitudinal end portion of the water tank;
a guidance pipe disposed in the water tank and extending from the inlet of the water tank toward a second longitudinal end portion of the water tank located opposite to the first longitudinal end portion of the water tank; and
a valve assembly configured to couple to a filter and including an inlet to connect to a water supply source and an outlet connected to the inlet of the water tank.

2. The refrigerator according to claim 1 , wherein the outlet of the water tank is positioned above the inlet of the water tank that is positioned above the filter while the filter is coupled to the valve assembly.

3. The refrigerator according to claim 1 , wherein the water tank and the filter each have an elongated body and are in parallel with each other while the filter is coupled to the valve assembly.

4. The refrigerator according to claim 1 , wherein the valve assembly further includes a valve housing on which a socket is formed, wherein the socket is configured to couple to a plug of the filter.

5. The refrigerator according to claim 4 , wherein a coupling protrusion protrudes from an outer surface of the plug of the filter and is supported by a holding protrusion of the socket when the filter is inserted to the valve housing.

6. A refrigerator, comprising:
a water tank including:
an elongated body defining a storage chamber for storing water;
an inlet and an outlet that are disposed at a part longitudinal end portion of the elongated body; and
a guidance pipe disposed inside the elongated body and extending from the inlet of the water tank along a longitudinal direction of the elongated body; and

a valve assembly configured to couple to a filter and including an inlet to connect to a water supply source and an outlet connected to the inlet of the water tank.

7. The refrigerator according to claim 6 , wherein the outlet of the water tank is positioned above the inlet of the water tank that is positioned above the filter while the filter is coupled to the valve assembly.

8. The refrigerator according to claim 6 , wherein water received through the inlet of the water tank is discharged from the guidance pipe and flows to the longitudinal end portion of the elongated body.

9. The refrigerator according to claim 6 , wherein the valve assembly is configured to supply water to the water tank from the water supply source or from the filter after water from the water supply source is purified by the filter.
