Abstract
A water purifying filter has a cylindrical inner housing to receive a filter therein, and an outer housing to receive the inner housing. The inner housing and the outer housing are spaced apart from each other to form an insulation space configured to suppress heat transfer and to reduce the filter freezing inside the inner housing.
Claims20
A water purifying filter assembly installable on a refrigerator through an installation hole, the water purifying filter assembly comprising:
- an inner housing having a cylinder tube shape and an open side, and configured to accommodate a filter inside the inner housing;
- an outer housing having an open side, a handle disposed on an opposite side of the open side of the outer housing, and a stopper configured to fit the installation hole of the refrigerator when the water purifying filter assembly is installed on the refrigerator, and wherein the outer housing is configured to accommodate the inner housing inside the outer housing such that an outer surface of the inner housing and an inner surface of the outer housing are separated by a first space which serves as an insulation space to suppress heat transfer between the inner housing and the outer housing,
- wherein
- the first space includes a first gap between a first position on the inner surface of the outer housing and a first position on the outer surface of the inner housing and a second gap, smaller than the first gap, between a second position on the inner surface of the outer housing and a second position on the outer surface of the inner housing,
- the first positions and the second positions are on a same cross section of the water purifying filter assembly,
- the first position on the outer surface of the inner housing radially corresponds to the first position on the inner surface of the outer housing with respect to a center of the cross section of the water purifying filter assembly, and
- the second position on the outer surface of the inner housing radially corresponds to the second position on the inner surface of the outer housing with respect to the center of the cross section of the water purifying filter assembly;
- and
- a connecting cap connecting the inner housing and the outer housing and covering the open side of the inner housing and the open side of the outer housing to define the first space,
- wherein the connecting cap, along with the inner housing, is configured to define a second space through which water from outside the water purifying filter assembly is guided to the filter, and to define a third space inside the connecting cap through which purified water from the filter is guided to outside the water purifying filter assembly.

A refrigerator comprising a main body having an installation hole, and a water purifying filter assembly for installing in the installation hole, the water purifying filter assembly comprising:
- an inner housing having a cylinder tube shape and an open side, and configured to accommodate a filter inside the inner housing;
- an outer housing having an open side, a handle disposed on an opposite side of the open side of the outer housing to receive an external force to rotate the water purifying filter assembly, and a stopper configured to fit the installation hole of the refrigerator when the water purifying filter assembly is installed on the refrigerator, and wherein the outer housing is configured to accommodate the inner housing inside the outer housing such that an outer surface of the inner housing and an inner surface of the outer housing are separated by a first space which serves as an insulation space to suppress heat transfer between the inner housing and the outer housing,
- wherein
- the first space includes a first gap between a first position on the inner surface of the outer housing and a first position on the outer surface of the inner housing and a second gap, smaller than the first gap, between a second position on the inner surface of the outer housing and a second position on the outer surface of the inner housing,
- the first positions and the second positions are on a same cross section of the water purifying filter assembly,
- the first position on the outer surface of the inner housing radially corresponds to the first position on the inner surface of the outer housing with respect to a center of the cross section of the water purifying filter assembly, and
- the second position on the outer surface of the inner housing radially corresponds to the second position on the inner surface of the outer housing with respect to the center of the cross section of the water purifying filter assembly:
- and
- a connecting cap connecting the inner housing and the outer housing, and covering the open side of the inner housing and the open side of the outer housing to define the first space,
- wherein the connecting cap, along with the inner housing, is configured to define a second space through which water from outside the water purifying filter assembly is guided to the filter, and to define a third space inside the connecting cap through which purified water from the filter is guided outside the water purifying filter assembly.
