Description

TECHNICAL FIELD

The present disclosure relates to a refrigerator in which an auxiliary storage box assembly for dividing and using a space is disposed in a cooling space.

BACKGROUND ART

An ordinary refrigerator is a home appliance having a cooling space so as to store food at a low temperature and may be divided into a refrigeration space and a freezing space depending on a temperature of stored food. Such a cooling space of the refrigerator is divided by a plurality of shelves so that containers, groceries, and the like various in size may be universally stored.

However, since the above cooling space is to universally receive the containers or the groceries various in size, greatly minutely dividing the space is difficult. In addition, always adjusting a height of a shelf depending on sizes of the stored containers or the stored groceries is restricted because a weight of the shelf itself is considerable, and also because adjustment is allowed after a loaded object is taken out. Thus, an inner space of the refrigerator has a difficulty in storing containers and groceries of a designed capacity. Even when a large amount of containers and groceries is stored by storing occasionally, efficiency is decreased because taking out and using afterward is difficult.

Thus, an auxiliary tool for effectively using such a cooling space of the refrigerator is actively researched currently.

FIG. 1 is a diagram illustrating a form in which a door of a refrigerator 100 according to an example embodiment of the present disclosure is removed and an auxiliary storage box assembly 200 is disposed in a cooling space 111.

Referring to FIG. 1, the refrigerator 100 according to an example embodiment may include a rectangular parallelepiped-shaped main body 110 of the refrigerator 100 and a refrigerator door (not illustrated) that selectively opens and closes the cooling space 111 of the main body 110 at a front of the main body 110. The cooling space 111 of the refrigerator 100 according to an example embodiment of the present disclosure may include a refrigeration space and a freezing space. The refrigerator 100 according to an example embodiment may have a bottom freezer structure in which the refrigeration space is provided to an upper part and the freezing space is provided to a lower part. The refrigeration space and the freezing space may each include a side-by-side door that is opened while rotating around a hinge of both end portions. However, the present invention is not limited to a refrigerator of the bottom freezer structure. When a refrigerator has a structure in which a shelf 120 having a form of a plane is positioned in the refrigeration space or the freezing space, the refrigerator may be applied to a refrigerator of a side-by-side structure in which the refrigeration space and the freezing space are disposed on a left side and a right side, respectively, a refrigerator of a top mount structure in which the freezing space is disposed above the refrigeration space, or the like.

The shelf 120 or a drawer-type storage space 130 for dividing the cooling space 111 may be disposed in the refrigeration space and the freezing space according to an example embodiment so as to increase space use efficiency, and the shelf 120 and the drawer-type storage space 130 may be disposed to be guided along a structure disposed on a left side and a right side.

An auxiliary storage box assembly 200 may be mounted to the shelf 120 of the refrigerator 100 according to an example embodiment. A storage box 230 may be disposed to the auxiliary storage box assembly 200 in a longitudinal direction or a transverse direction. Depending on a direction in which the storage box 230 of the auxiliary storage box assembly 200 is disposed, another element of the auxiliary storage box assembly 200, which is for fixing the storage box 230 to the shelf 120, may be different. Through this, occurrence of a dead zone occurring between the shelf 120 and another shelf 120 of the cooling space 111 may minimized. A further detailed description may be described below with reference to FIGS. 2 through 9.

A machine room isolated from the freezing space may be positioned in a rear lower part of the freezing space according to an example embodiment, a heat pump module (not illustrated) for operating the refrigerator 100 according to an example embodiment may be disposed in the machine room. The heat pump module may be a freezing cycle cooling device based on a refrigerant and include a compressor, a condenser, an expansion valve, and an evaporator.

(a) of FIG. 2 is a diagram illustrating a form in which the auxiliary storage box assembly 200 according to an example embodiment of the present disclosure is longitudinally installed, and (b) of FIG. 2 is a diagram illustrating a from in which the auxiliary storage box assembly 200 according to an example embodiment of the present disclosure is transversely installed.

A side used to describe the refrigerator 100 according to an example embodiment of the present disclosure may be a direction in which the cooling space 111 of the main body 110 is opened, namely, a front direction, and another side may be a rear direction as a direction opposite to the side. The above definition is not absolute, and as a direction of the side is changed, a direction of the other side may be also changed to correspond thereto.

The auxiliary storage box assembly 200 according to an example embodiment of the present disclosure may include the storage box 230, a slide bar 210, a hooking part 211, a fixation part 213, and a fixation protrusion 215.

The storage box 230 according to an example embodiment may be formed in a form of a rectangular parallelepiped box shape of which a surface is opened. In the storage box 230, on an opened surface, a first slide flange 231 may be formed at a pair of edges facing each other, and a second slide flange 233 may be formed at another pair of edges. The second slide flange 233 may be formed to be longer than the first slide flange 231. The first slide flange 231 or the second slide flange 233 may be placed on the slide bar 210 and move, and through this, the storage box 230 according to an example embodiment may be withdrawn or stored.

The slide bar 210 according to an example embodiment may be positioned on a bottom surface of the shelf 120. A pair of slide bars 210 may be formed to be spaced apart by a predetermined distance so as to face each other. The slide bar 210 according to an example embodiment may provide a movement path of the storage box 230. The first slide flange 231 or the second slide flange 233 of the storage box 230 may be placed on the slide bar 210 and move. When being longitudinally installed, the auxiliary storage box assembly 200 is assembled so that the second flange 233 of the storage box 230 moves on the slide bar 210, or when being transversely installed, the auxiliary storage box assembly 200 is assembled so that the first flange 231 of the storage box 230 moves on the slide bar 210.

The hooking part 211 according to an example embodiment may be extended from an end portion of the slide bar 210 and formed to surround a front edge of the shelf 120 and a portion of an upper surface of the shelf 120. That is, the hooking part 211 may provide coupling force so that the auxiliary storage box assembly 200 may be coupled to the shelf 120.

The fixation part 213 according to an example embodiment may be formed at another end portion of the slide bar 210 and formed to surround a rear edge of the shelf 120. The fixation part 213 may be formed to have a thickness to a degree to which the fixation part 213 may pass through a space between the rear edge of the shelf 120 and a wall surface of the cooling space 111. In other words, as the fixation part 213 is formed to surround only the rear edge of the shelf 120 and formed to have the thickness to the degree to which the fixation part 213 may pass through the space between the rear edge of the shelf 120 and the wall surface of the cooling space 111, the auxiliary storage box assembly 200 may be coupled to the shelf 120 even without detaching the shelf 120.

The fixation protrusion 215 according to an example embodiment may be formed at an end of the fixation part 213 and formed to surround at least a portion of the upper surface of the shelf 120. The fixation protrusion 215 may be disposed at the end of the fixation part 213 in a rotatable manner.

When the fixation protrusion 215 passes through the space between the rear edge of the shelf 120 and the wall surface of the cooling space 111 together with the fixation part 213 in a state of rotating to be perpendicular to the slide bar 210, and when the fixation protrusion 215 rotates so as to rotate to be parallel to the slide bar 210 thereafter, the at least a portion of the upper surface of the shelf 120 may be surrounded. Through this, the coupling force of the auxiliary storage box assembly 200 to the shelf 120 may be enhanced.

The spacer 220 according to an example embodiment may connect the end portion of the slide bar 210 with another, connect the other end portion of the slide bar 210 with another, and formed on the bottom surface of the shelf 120. The spacer 220 according to an example embodiment may enhance the coupling force of the auxiliary storage box assembly 220 to the shelf 120 on the bottom surface of the shelf 120 together with the hooking part 211 and the fixation protrusion 215 and secure a space in which the storage box 230 may move by securing a space between the slide bar 210 and the bottom surface of the shelf 120.

(a) of FIG. 3 is a diagram illustrating a structure before the auxiliary storage box assembly 200 according to an example embodiment of the present disclosure being coupled to the shelf 120, and (b) of FIG. 3 is a diagram illustrating a structure after the auxiliary storage box assembly 200 according to an example embodiment of the present disclosure being coupled to the shelf 120.

(a) of FIG. 3 shows a state in which the fixation protrusion 215 according to an example embodiment rotates so as to be perpendicular to the slide bar 210, and (b) of FIG. 3 shows a state in which the fixation protrusion 215 is parallel to the slide bar 210 by rotating. In other words, the fixation protrusion 215 passes through a space between a rear edge of the shelf 120 and a wall surface of the cooling space 111 together with the fixation part 213 in the state of (a) of FIG. 3 and surrounds at least a portion of an upper surface of the shelf 120 by rotating to be in the state of (b) of FIG. 3. Through this, coupling force of the auxiliary storage box assembly 200 to the shelf 120 may be enhanced.

FIG. 4 is a diagram illustrating a fixation member 217 of the auxiliary storage box assembly 200 according to an example embodiment of the present disclosure.

The fixation member 217 according to an example embodiment may have a size to be inserted into a space between a rear edge of the shelf 120 and a wall surface of the cooling space 111 and may be formed to surround the fixation part 213 and a rotation axis of the fixation protrusion 215. Through this, the auxiliary storage box assembly 200 may be prevented from being separated from the shelf 120 by preventing rotation of the fixation protrusion 215.

FIG. 5 is a diagram illustrating a coupling structure of another form of the auxiliary storage box assembly 200 according to an example embodiment of the present disclosure.

For example, a connection bar 214 for connecting fixation parts 213, which are formed at other end portions of the pair of slide bars 210, with each other may be further included, and the fixation protrusion 215 may be formed to be coupled and rotate on the connection bar 214. The fixation protrusion 215 may be formed at not only an end of the fixation part 213 but also on any point on the connection bar 214. Through this, fixation force of the auxiliary storage box assembly 200 for the shelf 120 may be distributed in a balanced manner.

(a) of FIG. 6 is a diagram illustrating a form in which the auxiliary storage box assembly 200 according to another example embodiment is longitudinally installed, and (b) of FIG. 6 is a diagram illustrating a from in which the auxiliary storage box assembly 200 according to another example embodiment is transversely installed.

The auxiliary storage box assembly 200 according to another example embodiment of the present disclosure will be compared to the auxiliary storage box assembly 200 which is illustrated in (a) of FIG. 2 and (b) of FIG. 2, and a difference therein will be mainly described.

FIG. 7 is an exploded diagram illustrating a coupling structure of the auxiliary storage box assembly 200 according to another example embodiment of the present disclosure. (a) of FIG. 8 is a diagram illustrating a form in which a spacer 320 according to another example embodiment of the present disclosure is narrowed, and (b) of FIG. 8 is a diagram illustrating a form in which the spacer 320 according to another example embodiment of the present disclosure is widened.

The storage box 230 and a hooking part 311 according to another example embodiment of the present disclosure are similar to the storage box 230 and the hooking part 211 which are illustrated in (a) of FIG. 2 and (b) of FIG. 2.

A slide bar 310 and a fixation part 313 according to another example embodiment may be formed to be separated from and coupled to each other, not integrally formed.

A fixation protrusion 315 according to another example embodiment may be formed by extending from an end of the fixation part 313 and formed to surround at least a portion of an upper surface of the shelf 120.

The spacer 320 according to another example embodiment of the present disclosure may be similar to the slide bar 210 of (a) of FIG. 2 and (b) of FIG. 2 in terms of connecting an end portion of the slide bar 310 with another, connecting another end portion of the slide bar 310 with another, and being formed on a bottom surface of the shelf 120. Similarly, the spacer 320 according to another example embodiment may enhance coupling force of the auxiliary storage box assembly 200 to the shelf 120 together with the hooking part 311 and the fixation protrusion 315 at the bottom surface of the shelf 120 and secure a space in which the storage box 230 may move by securing a space between the slide bar 310 and the bottom surface of the shelf 120. However, a difference is present in that a length of the spacer 320 changes.

Referring to FIG. 7 through (b) of FIG. 8, the spacer 320 according to another example embodiment may include a rail 321 and a rail body 323.

The rail 321 according to another example embodiment may be formed by protruding from one of a pair of slide bars 310, and the rail body 323 according to another example embodiment may be formed to surround the rail 321 by protruding from another one of the pair of slide bars 310. An interval between the pair of slide bars 310 may be adjusted by slide movement on the rail 321 and the rail body 323.

The interval between the slide bars 310 may be changed depending on a direction (e.g., a longitudinal direction or a transverse direction) in which the auxiliary storage box assembly 200 according to another example embodiment is coupled. For example, the interval between the slide bars 310 may be changed to correspond to a length of the first slide flange 231 or a length of the second slide flange 233 of the storage box 230. In other words, when the auxiliary storage box assembly 200 is longitudinally coupled as illustrated in (a) of FIG. 8, the interval between the slide bars 310 may be changed to be narrowed as the rail 321 and the rail body 323 moves in a sliding manner. When the auxiliary storage box assembly 200 is transversely coupled as illustrated in (b) of FIG. 8, the interval between the slide bars 310 may be changed to be widened as the rail 321 and the rail body 323 moves in a sliding manner.

(a) of FIG. 9 through (c) of FIG. 9 are diagrams illustrating a structure in which the slide bar 310 and the fixation part 313 of the auxiliary storage box assembly 200 according to another example embodiment of the present disclosure are coupled.

The fixation part 213 according to another example embodiment of the present disclosure may further include a coupling part 314 and a protrusion 314a. Another coupling part 314 of the present disclosure may be formed in parallel with another end portion of the slide bar 310 and formed so that each overlaps another. At this point, the protrusion 314a which protrudes toward the slide bar 310 may be formed to the coupling part 314, and a hole 312 corresponding thereto may be formed to the slide bar 310. As the protrusion 314a of the coupling part 314 is inserted into the hole 312 of the slide bar 310, the slide bar 310 and the fixation part 313 may be firmly coupled. Conversely, the hole 312 may be formed to the coupling part 314, and the protrusion 314a which protrudes toward the coupling part 314 may be formed to the slide bar 310.

The fixation part 313 and the slide bar 310 according to another example embodiment of the present disclosure may improve fixation force through screw coupling that penetrates the coupling part 314 and the slide bar 310 in addition to insertion coupling of the protrusion 314a and the hole 312.

FIG. 10 is a diagram illustrating a structure in which an auxiliary storage box 230 is disposed in the cooling space 111 of the refrigerator 100 according to another example embodiment of the present disclosure. FIG. 11 is a diagram enlarging a form in which the storage box 230 according to another example embodiment of the present disclosure is disposed.

The drawer-type storage space 130 may be formed in the cooling space 111 of the refrigerator 100 according to various example embodiments of the present disclosure. At this point, the storage box 230 of the auxiliary storage box assembly 200 may be disposed and used in the drawer-type storage space 130. For example, the first slide flange 231 or the second slide flange 233 of the storage box 230 may be disposed to be placed on a wall opposite to the drawer-type storage space 130 and move in a sliding manner and may be used. When food containers or ingredients various in size are stored in a shelf, at some point, the auxiliary storage box assembly 200 may not be required because a dead zone does not occur on a bottom surface of the shelf 120. In this case, only the storage box 230 may be separated to be disposed and used in the drawer-type storage space 130. Through this, usability of the auxiliary storage box assembly 200 may be increased.

It is apparent to those skilled in the art that the present disclosure may be implemented in another specific form within a range not deviating from the spirit and essential characteristics of the present disclosure.

The above detailed description is not to be limitedly construed in all aspects and should be considered as an example.
