Referring to FIGS. 1 to 3, the refrigerator 1 according to one embodiment of the present disclosure may include a main body 110 defining an outer body of the refrigerator. The main body includes a storage compartment S, and a door 120 rotatably mounted to the main body 110 and configured to seal the storage compartment S.
In this regard, the refrigerator 1 according to one embodiment of the present disclosure may be of any type that is well known in the art, such as a top-mount-type refrigerator, a bottom-freeze-type refrigerator, and etc.
The storage compartment S may be disposed in the main body 110 of the refrigerator 1. The storage compartment S may be divided into a plurality of storage regions, e.g., by a rack 200.
The rack 200 may sit on guide rails 130 that protrude horizontally from the inner sidewalls of the storage compartment S. As shown, the rack 200 may divide the storage compartment S into a lower region and an upper region.
The rack 200 can be inserted along the guide rails 130 by a user. After installation, the rack is seated on the upper surfaces of the guide rails 130.
Hereinafter, the configuration of the exemplary rack in the refrigerator 1 according to one embodiment of the present disclosure is described with reference to FIGS. 4 to 7.
FIG. 4 is a perspective view illustrating the configuration of the exemplary rack according to one embodiment of the present disclosure. FIG. 5 is another perspective view illustrating the configuration of the rack according to one embodiment of the present disclosure. FIG. 6 is a front view illustrating the configuration of the exemplary rack according to one embodiment of the present disclosure. FIG. 7 is a side view illustrating the configuration of the exemplary rack according to one embodiment of the present disclosure.
Referring further to FIGS. 4 to 7, the rack 200 divides the storage compartment S of the refrigerator 1 into a plurality of storage regions. The rack 200 may include a plate member 210 and support parts 220.
After being installed, the plate member 210 horizontally extends across the storage compartment S and generally divides the storage compartment S into an upper region and a lower region. The plate member 210 may be manufactured by, for example, injection-molding a resin material.
The support parts 220 may be affixed to the plate member 210. The support parts 220 can sit on the guide rails 130 protruding from the inner sidewalls of the storage compartment S. The support parts 220 may be disposed at the opposite lateral ends of the plate member 210.
Each of the support parts 220 may include a first seating portion 221 and a second seating portion 222 of different height positions. The first seating portion 221 and the second seating portion 222 may have seating projections 223.
The first seating portion 221 may be coupled to each of the opposite lateral ends of the plate member 210. A first seating projection 223 a may be disposed on the lower surface of the first seating portion 221 and protrude downward in a thickness direction (vertically). A recess 131 may be disposed on the upper surface of each of the guide rails 130. The recess 131 is depressed inward and has a shape conformal to the shape of the first seating projection 223 a. Thus, during installation, the first seating portion 221 may slide along each of the guide rails 130 and eventually sit on the upper surface of each of the guide rails 130.
When the first seating portion 221 sits on the upper surface of each of the guide rails 130, the first seating projection 223 a may be in a state of being inserted into the recess 131. The term “thickness direction” used herein may refer to an up-down (vertical) direction in FIG. 2. With the first seating projection 223 a being inserted and fit into the recess 131, undesired movement of the rack 200 can be reduced or completely prevented.
The second seating portion 222 may be disposed on the lower surface of the first seating portion 221. The second seating portion 222 may protrude downward along the thickness direction from the lower surface of the first seating portion 221. The second seating portion 222 may be integrally manufactured with the first seating portion 221, e.g., may be simultaneously injection-molded with the first seating portion 221. Alternatively, the second seating portion 222 may be manufactured as a separate component from the first seating portion 221. The second seating portion 222 may be affixed to the first seating portion 221 in any suitable manner that is well known in the art, such as bonding, mechanical coupling and the like.
The second seating portion 222 may extend from the lower surface of the first seating portion 221. For example, the second seating portion 222 may include an extension wall portion 222 a extending downward along the thickness direction from the lower surface of the first seating portion 221. The second seating portion 222 may also include a bent portion 222 b bent outward from a lower end of the extension wall portion 222 a in parallel with the first seating portion 221.
The extension wall portion 222 a may serve as a spacer between the first seating portion 221 and the bent portion 222 b of the second seating portion 222 in the thickness direction. The bent portion 222 b may be formed by bending the end portion of the extension wall portion 222 a. The end of the bent portion 222 b and the end of the first seating portion 221 may be aligned along the thickness direction. In other words, the longitudinal distance from the end of the first seating portion 221 at one side of the plate member 210 to the first seating portion 221 provided at the other end of the plate member 210 may equal the longitudinal distance from the end of the bent portion 222 b disposed at one side of the plate member 210 to the bent portion 222 b disposed at the other side of the plate member 210. The term “longitudinal” used herein may refer to the left-right direction in FIG. 2.
Seating projections 223 may be disposed in the bent portion 222 b. For example, a second seating projection 223 b may be disposed on the upper surface of the bent portion 222 b and a third seating projection 223 c may be disposed on the lower surface of the bent portion 222 b. In this case, the second seating projection 223 b and the third seating projection 223 c may have substantially the same shape. The first seating projection 223 a, the second seating projection 223 b and the third seating projection 223 c may be aligned along the thickness direction.
The second seating portion 222 may sit on each of the guide rails 130. For example, the bent portion 222 b of the second seating portion 222 may sit on the upper surface of each of the guide rails 130. In this case, the recess 131 may be disposed in each of the guide rails 130. When the bent portion 222 b sits on each of the guide rails 130, the second seating projection 223 b or the third seating projection 223 c may fit in the recess 131.
As described above, the rack 200 according to one embodiment of the present disclosure includes the first seating portion 221 and the second seating portion 222. It can advantageously partition the storage compartment S into a plurality of regions in various partition configurations using one rack 200. Hereinafter, different examples in which the rack 200 is coupled to the refrigerator 1 according to one embodiment of the present disclosure are described with reference to FIGS. 8A to 8C.
Referring first to FIG. 8A, the first seating portion 221 may sit on each of the guide rails 130. Moved by a user, the first seating portion 221 may slide along each of the guide rails 130 and may then sit on each of the guide rails 130. The first seating projection 223 a disposed on the lower surface of the first seating portion 221 may fit in the recess 131 of each of the guide rails 130. In the example illustrated in FIG. 8A, the storage compartment S can be divided into an upper space and a lower space of similar sizes.
Referring to FIG. 8B, the second seating portion 222 may sit on each of the guide rails 130. During installation, the second seating portion 222 may slide along each of the guide rails 130 and may eventually sit on each of the guide rails 130. In this case, the third seating projection 223 c disposed on the lower surface of the bent portion 222 b of the second seating portion 222 may be inserted into and fit in the recess 131 of each of the guide rails 130. As a result, the plate member 210 of the rack 200 may be positioned higher within the storage compartment S by the height of the extension wall portion 222 a than when the first seating portion 221 sits on each of the guide rails 130.
Referring to FIG. 8C, the second seating portion 222 may sit on each of the guide rails 130. In the example illustrated in FIG. 8C, the rack 200 may be placed upside down. That is, the example illustrated in FIG. 8C is similar to the example illustrated in FIG. 8B in that the second seating portion 222 sits on each of the guide rails 130. However, the example illustrated in FIG. 8C differs from the example illustrated in FIG. 8B in that the rack 200 is mounted in an inverted state. In other words, in the example illustrated in FIG. 8C, the second seating projection 223 b disposed on the upper surface of the bent portion 222 b of the second seating portion 222 may be inserted into and fit in the recess 131 of each of the guide rails 130. Thus, the plate member 210 of the rack 200 may be positioned lower within the storage compartment S by the height of the extension wall portion 222 a than when the first seating portion 221 sits on each of the guide rails 130.
As described above, in the refrigerator 1, one of the first to third seating projections 223 a, 223 b and 223 c may be selected for coupling to the recess 131 of each of the guide rails 130. The storage compartment S may be partitioned into a plurality of spaces with different sizes depending on which of the seating projections 223 is coupled.
In the refrigerator 1, the rack 200 includes the support parts 220 that each includes the first seating portion 221 and the second seating portion 222 with different heights. The storage compartment S can be divided into different spatial configurations according to various needs of users.
From the foregoing, it will be appreciated that various embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. The exemplary embodiments disclosed in the specification of the present disclosure do not limit the present disclosure.
