FIG. 1 shows a refrigerator, according to an embodiment of the disclosure. FIG. 2 is a schematic side cross-sectional view of the refrigerator of FIG. 1.

Referring to FIGS. 1 and 2, a refrigerator 1 may include a main body 10 having storerooms 21, 22, and 23, doors 30 and 40 arranged to open or close the storerooms 21, 22, and 23, and a cold air supply device (not shown) for supplying cold air to the storerooms 21, 22, and 23.

The main body 10 may include an inner case 11 that defines the storerooms 21, 22, and 23, an outer case 12 coupled onto the outer side of the inner case 11, and insulation 13 arranged between the inner case 11 and the outer case 12. The inner case 11 may be formed of a plastic substance through injection molding, and the outer case 12 may be formed of a metal substance. The outer case 12 may also be referred to as a cabinet 12. For the insulation 13, a urethane foam insulation may be used, and a vacuum insulation panel may also be used along with the urethane foam insulation as required. The main body 10 may include middle walls 17 that vertically divide the storerooms 21, 22, and 23. The storerooms 21, 22, and 23 may be divided into first, second, and third storerooms 21, 22, and 23. The inner case 11 may further include a top side 11a, a rear side 11b, both sides (i.e., left and right sides), and a front side 11c.

The storerooms 21, 22, and 23 may be used as a fridge maintained at temperatures of about 0 to 5 degrees Celsius for keeping groceries cool, and a freezer maintained at temperatures of about minus 30 to 0 degrees Celsius for keeping groceries frozen.

The storerooms 21, 22, and 23 are formed to have an open front through which to take out or put in groceries, and the open front may be opened or closed by the doors 30 and 40. The storerooms 21, 22, and 23 may have shelves 27 to put groceries thereon.

There may be a plurality of shelves 27. The shelves 27 may include a first shelf 27a arranged uppermost in the storeroom 21, a second shelf 27b arranged under the first shelf 27a, and a third shelf 27c arranged under the second shelf 27b. In other words, the second shelf 27b may be arranged between the first shelf 27a and the third shelf 27c. However, the number of the shelves is not limited to three, and there may be four or more or two or less of the shelves.

The first storeroom 21 may be partitioned into a plurality of spaces. The plurality of spaces may include a first space 21a, a second space 21b, a third space 21c, and a fourth space 21d. The first space 21a may be formed between a top wall that makes up the storeroom 21 and the first shelf 27a. The second space 21b may be arranged under the first space 21a and between the first shelf 27a and the second shelf 27b. The third space 21c may be arranged under the second space 21b and formed between the second shelf 27b and the third shelf 27c. In other words, the second space 21b may be arranged between the first space 21a and the third space 21c. The fourth space 21d may be arranged underneath the third shelf 27c. In other words, it may be the lowest of the plurality of spaces. A drawer 28 may be provided in the storeroom 21, for example below shelf 27c, as shown in FIG. 1.

The door 30 may be coupled to the main body 10 to be rotated to the left or right. Door guards 31 may be provided on the rear surface of the door 30 to store groceries.

The door 40 may be provided to slide into or out of the storeroom 22 or 23, and may include a door part 41 covering the open front of the storeroom 22 or 23 and a basket 43 coupled to the rear surface of the door part 41. The basket 43 may be supported by a rail 45 to slide. A handle 41a may be formed on the door part 41.

The cold air supply device may generate cold air by using latent heat of a refrigerant through a cooling cycle. The cold air supply device may include a compressor 2, a condenser, an expansion device, evaporators 3 and 4, and blower fans 6 and 7. The evaporators 3 and 4 may also be referred to as heat exchangers 3 and 4.

The evaporator 3 may be arranged behind the storeroom 21 to produce cold air. The evaporator 3 may be accommodated in a cooling room 3a formed by an evaporator cover 5. A suction port 5a may be formed at the evaporator cover 5 and air may be sucked from the storeroom 21 into the cooling room 3a through the suction port 5a.

The blower fan 6 may be provided in the cooling room 3a to circulate air. The cooling room 3a may be connected to a cold air guide assembly 50 for guiding cold air of the cooling room 3a. With this structure, when the blower fan 6 is operating, the air is sucked into the cooling room 3a from the storeroom 21 through the suction port 5a, and the air sucked in may be cooled down by the evaporator 3 and then guided to the cold air guide assembly 50.

The cold air guide assembly 50 may include a rear guide 60 arranged behind the storeroom 21 and a top guide 70 arranged on top of the storeroom 21.

The rear guide 60 may include a rear fluid path 61 for guiding the cold air produced from the evaporator 3, and a cold air supply port 62a and 63a for supplying the cold air into the storeroom 21 from the rear fluid path 61 to cool down the storeroom 21. The cold air supply port 62a and 63a may supply the cold air into the first space 21a. The air sucked in through the suction port 5a may pass through the evaporator 3 and the blower fan 6 and may then be supplied into the storeroom 21 through the cold air supply port 62a and 63a. The rear guide 60 may serve as a cold air supply device 60.

In FIG. 2, it is shown that the suction port 5a is arranged on the bottom while the cold air supply port 62a and 63a is provided on the top, so that the air flows from bottom to top in the storeroom 21. That is, it is shown that air is sucked from the fourth space 21d and supplied to the first space 21a. It is not, however, limited thereto, and the air may be sucked from the first space 21a and supplied to the fourth space 21d.

The top guide 70 may include a top fluid path 71 connected to the rear fluid path 61, a discharge port 72 for forming an air curtain across the open front of the storeroom 21 or for discharging cold air into the storeroom 21 from the top fluid path 71, and a damper 75 for controlling an amount of cold air supplied to the discharge port 72.

A cold air guide 90 may be arranged across the discharge port 72 to control an opening or closing of the discharge port 72. The cold air guide 90 may be arranged to be adjacent to the top wall of the inner case 11. In other words, the cold air guide 90 may be arranged on one wall of the storeroom 21. The cold air guide 90 and the discharge port 72 may be arranged to be adjacent to the door 30. Specifically, the cold air guide 90 and the discharge port 72 may be arranged to be adjacent to the open front. The cold air guide 90 and the discharge port 72 are not, however, limited to these positions, but may be arranged in many different positions.

With this structure, when the blower fan 6 is operating and the cold air guide 90, arranged to be adjacent to the top wall of the inner case 11, opens the discharge port 72, the cold air produced from the evaporator 3 may sequentially pass through the rear fluid path 61 and the top fluid path 71 and may be discharged down into the storeroom 21 through the discharge port 72, and may cause a direction of the cold air discharged through the cold air supply port 62a and 63a of the storeroom 21 to be changed.

For example, the cold air discharged through the cold air supply port 62a and 63a may flow to an area adjacent to the door 30 or the open front, and the cold air may be discharged through the discharge port 72 arranged on the top wall of the inner case 11 adjacent to the door 30. As the cold air is discharged down through the discharge port 72, it may be discharged toward the cold air supplied through the cold air supply port 62a and 63a, directing the cold air that has reached the area adjacent to the door 30 downwards.

In this case, an angle at which and a direction in which the cold air is discharged down through the discharge port 72 may be controlled by rotating a blade 92 (see FIG. 7) of the cold air guide 90. A direction toward which the cold air supplied through the cold air supply port 62a and 63a flows may be changed depending on the discharging angle and direction of the cold air from the discharge port 72.

Accordingly, the discharge port 72 and the cold air guide 90 may send the cold air supplied through the cold air supply port 62a and 63a to the second space 21b, third space 21c, and fourth space 21d. With this structure, groceries in the second space 21b, third space 21c, and fourth space 21d may be kept fresh. Furthermore, when the cold air guide 90 is used, temperature differences between the first, second, third, and fourth spaces 21a, 21b, 21c, and 21d may be reduced.

When the blower fan 6 is operating and the cold air guide 90 blocks the discharge port 72, the cold air produced from the evaporator 3 may be discharged into the storeroom 21 through the cold air supply port 62a and 63a to cool down the storeroom 21.

The top guide 70 may be equipped with the damper 75 for regulating an amount of the cold air supplied to the discharge port 72. The damper 75 may be able to regulate an amount of the cold air supplied to the discharge port 72, so when much of the cold air needs to be supplied into a lower one of the plurality of spaces 21a, 21b, 21c and 21d in the storeroom 21, the damper 75 may be opened altogether.

FIG. 3 is a perspective view illustrating a guide of the refrigerator of FIG. 1. FIG. 4 is a perspective view illustrating the rear side of the guide of the refrigerator of FIG. 1. The damper 75 is omitted in FIGS. 3 and 4.

Referring to FIGS. 3 and 4, the cold air guide assembly 50 may include a rear guide 60 arranged behind the storeroom 21 and a top guide 70 arranged on top of the storeroom 21. The rear guide 60 and the top guide 70 may be integrally formed, but in the embodiment of the disclosure, the rear guide 60 and the top guide 70 may be separately provided and assembled together to form the cold air guide assembly 50.

For this, the rear guide 60 and the top guide 70 may each include a coupling portion (not shown). The coupling portions may be coupled together through various fitting structures and various coupling structures including a structure coupled with a separate fastening member such as a pin, a screw, a bolt, a rivet, or the like. Further, the rear guide 60 and the top guide 70 may be provided to be detachable from each other.

As such, the rear guide 60 and the top guide 70 may be provided to be attachable to and detachable from each other instead of being integrally formed.

The rear guide 60 may include the rear fluid path 61 for guiding the cold air produced from the evaporator 3, and the cold air supply port 62a and 63a for discharging the cold air into the storeroom 21 from the rear fluid path 61 to cool down the storeroom 21. Cold air discharged through a discharge port 9 of a blower fan case 8 may flow into an inlet 61a of the rear fluid path 61.

The rear guide 60 may include a front cover 62 facing the storeroom 21, a middle cover 63 coupled onto the rear surface of the front cover 62, a pair of middle guide walls 65 arranged to protrude from the middle cover 63 and face each other to form the rear fluid path 61, and a rear cover 64 arranged behind the middle cover 63 and coupled to correspond to the middle guide walls 65 to form the rear fluid path 61.

The rear guide 60 may be coupled to the rear surface of the storeroom 21, and the rear fluid path 61 may be surrounded by the middle cover 63, the middle guide walls 65, and the rear cover 64.

The top guide 70 may include the top fluid path 71 connected to the rear fluid path 61, and the discharge port 72 through which to discharge the cold air down into the storeroom 21 from the top fluid path 71 to supply the cold air to the second, third, and fourth spaces 21b, 21c and 21d of the storeroom 21.

The top guide 70 may include a cover top 73 that separates the storeroom 21 from the top fluid path 71, and a pair of top guide walls 74 arranged to protrude from the cover top 73 and face each other to form the top fluid path 71. The top guide walls 74 may guide the cold air to the cold guide 90, which will be described later. The top fluid path 71 may guide the cold air to the cold air guide 90.

The top guide 70 may be coupled onto the top side 11a of the inner case 11, and the top fluid path 71 may be formed by the cover top 73, the pair of top guide walls 74, and the inner case 11. Alternatively, there may be an extra cover member (not shown) arranged between the top guide 70 and the inner case 11, in which case the top fluid path 71 may be surrounded by the top guide 70, the pair of top guide walls 74, and the cover member.

The top guide 70 may cause the cold air produced from the evaporator 3 to flow to the cold air guide 90. Specifically, the cold air may flow to the cold air guide 90 and the discharge port 72 through the top fluid path 71 of the top guide 70.

As described above, the cold air discharged through the cold air supply port 62a and 63a may flow to an area adjacent to the door 30 or the open front, and the cold air may be discharged through the discharge port 72 arranged on the top wall of the inner case 11 adjacent to the door 30. As the cold air is discharged down through the discharge port 72, it may be discharged toward the cold air supplied through the cold air supply port 62a and 63a, directing the cold air that has reached the area adjacent to the door 30 downwards.

Accordingly, the direction of the cold air discharged through the cold air supply port 62a and 63a may be controlled so that the cold air flows to the second space 21b, third space 21c, and fourth space 21d.

The blower fan 6 may be arranged on the bottom between the front cover 62 and the rear cover 64. This may enable the cold air flowing between the middle guide walls 65 formed on the middle cover 63 to be sent to the top guide 70.

FIG. 5 is an exploded view of the rear guide of the refrigerator of FIG. 1. FIG. 6 is an exploded view of the rear guide of the refrigerator of FIG. 1, which is viewed from behind.

Referring to FIGS. 5 and 6, the rear guide 60 may include the front cover 62, the middle cover 63, the rear cover 64, and the cold air supply port 62a and 63a.

The cold air supply port 62a and 63a may include the front cold air supply port 62a and the middle cold air supply port 63a. The front cover 62 may include the front cold air supply port 62a. The middle cover 63 may include the middle cold air supply port 63a.

The front cover 62 may have a surface facing the storeroom 21. The front cover 62 may include a top end 62b, both side ends 62c, a bottom end 62e, and a bending part 62d. The front cover 62 may include a cut 62a formed inwards from the top end 62b of the front cover 62. The cut 62a may serve as a front cold air supply port 62a. In other words, the top end 62b may be cut inwards to form the front cold air supply port 62a. The front cold air supply port 62a may be arranged to be adjacent to the top wall of the storeroom 21. It is not, however, limited thereto. For example, the front cold air supply port 62a may be formed by being cut inwards from both side ends 62c or from the bottom end 62e of the front cover 62. Also, the front cover 62 may include a recess 62f. The recess 62f may be recessed from one end 62b, 62c and 62e of the front cover 62. The recess 62f may form a cold air supply port 62a.

The front cold air supply port 62a may be recessed inwards from each of the ends 62b, 62c, and 62e of the front cover 62. Accordingly, there is no need for extra perforation to form the cold air supply port.

Although it is shown that the cut 62a is made inwards from the top end 62b of the front cover 62, it is not limited thereto and it may be formed by being cut inwards from either side end 62c or the bottom end. Alternatively, a plurality of cuts 62a may be formed.

The cut 62a is connected to the middle cold air supply port 63a when the front cover 62 is coupled to the middle cover 63, which will be described later, and then the cut 62a may perform the function of the front cold air supply port 62a.

As the front cold air supply port 62a is to be connected to the middle cold air supply port 63a, the front cold air supply port 62a and the middle cold air supply port 63a may be formed to have a matching shape. For example, the front cold air supply port 62a and the middle cold air supply port 63a may be formed to be long in the horizontal direction and short in the vertical direction. Furthermore, the front cold air supply port 62a and the middle cold air supply port 63a may be formed in the same size.

In an embodiment of the disclosure, as the front cold air supply port 62a is formed by being cut inwards from the end 62b, 62c or 62e or the bending part 62d of the front cover 62, no extra post-processing is required after the cover is formed. Accordingly, processing and production costs may be reduced. In a case that the front cover 62 is formed of a glass material, when the cold air supply port 62a is formed by perforating the inside glass after the front cover 62 is formed, strength of the front cover 62 may be significantly reduced. In the embodiment of the disclosure, however, the cold air supply port 62a is formed by being cut from an end of the front cover 62, so there is no need for extra perforation and the strength of the front cover 62 may be maintained.

The middle cover 63 may be arranged between the front cover 62 and the rear cover 64. The middle cover 63 may include a top end 63b, both side ends 63c, a bending part 63d, and a bottom end 63e.

The middle cover 63 may also include the middle cold air supply port 63a, deformation relief grooves 63f, middle guide walls 65, and communication holes 68.

The middle cold air supply port 63a may be formed at an end of the middle cover 63. In other words, it may be formed at an edge of the middle cover 63. The middle cold air supply port 63a may receive cold air produced from the evaporator 3 and send the cold air to the front cold air supply port 62a. Furthermore, the front cold air supply port 62a and the middle cold air supply port 63a may be connected.

The deformation relief grooves 63f may be formed on the inner side of the middle cover 63 (i.e., a side facing the storeroom 21). The deformation relief grooves 63f may be provided to prevent the middle cover 63 from being destroyed when the size of the middle cover 63 is changed due to changes in temperature in the refrigerator 1. That is, the deformation relief grooves 63f may relieve shock from the change in size.

The middle guide walls 65 may guide the cold air to flow in between the top guide walls 74. The air that has passed through the middle guide walls 65 may flow to the middle cold air supply port 63a and the communication hole 68.

The middle guide walls 65 may form the communication hole 68. The communication hole 68 may allow the cold air to flow from the middle guide walls 65 to the top guide walls 74. The communication hole 68 may be arranged to be adjacent to the middle cold air supply port 63a. For example, the communication hole 68 may be arranged farther up than the middle cold air supply port 63a. Hence, some of the cold air produced from the evaporator 3 may be supplied to the middle cold air supply port 63a and some others may be supplied to the communication hole 68. The cold air flowing to the communication hole 68 may be supplied to the cold air guide 90.

The communication hole 68 may allow the cold air flowing to the rear guide 60 to flow to the top guide 70. That is, the communication hole 68 may connect the rear fluid path 61 to the top fluid path 71. With this, the cold air that has passed through the top fluid path 71 may be supplied to the cold air guide 90.

Although the communication hole 68 is shown to have a plurality of holes, it is not limited thereto and it may be formed as a single hole, which is formed to be longer in one direction.

A longer side of the middle cold air supply port 63a may be greater than the longer side of the communication hole 68. It is not, however, limited thereto, and the longer side of the communication hole 68 may be greater than the longer side of the middle cold air supply port 63a.

As described above, the damper 75 may be arranged in the downstream of the communication hole 68 to regulate the cold air flowing to the top guide walls 74 and the cold air guide 90.

The rear cover 64 may be arranged behind the middle cover 63. The rear cover 64 may have a size and a shape matching the middle guide wall 65. The middle cover 63 and the rear cover 64 may be coupled to form a duct that allows the cold air to flow therein. Furthermore, the middle guide walls 65 and the rear cover 64 may form the rear fluid path 61 in which the cold air flows. Although the rear cover 64 is shown to correspond to the shape of the middle guide walls 65, it is not limited thereto and the rear cover 64 may be formed to cover the entire middle cover 63.

The cold air supply port 62a and 63a may be formed to be longer in the horizontal direction than in the vertical direction. Accordingly, the cold air supply port 62a and 63a is hardly noticeable to the user, thereby improving aesthetic properties.

The front cover 62 may be formed to supply cold air into the storeroom 21 through the front cold air supply port 62a. Other components than the cold air supply port 62a may not supply the cold air into the storeroom 21. In other words, no multiple supply ports or holes are formed on inner portions of the front cover 62, and the cold air may be supplied into the storeroom 21 through the front cold air supply port 62a formed at the respective ends 62b, 62c, and 62e of the front cover 62. Furthermore, without perforating the front cover 62, the multiple cold air supply ports 62a may be formed by being cut from the respective ends 62b, 62c and 62e. Accordingly, the beauty of an area visible to the user may increase.

FIG. 7 is a diagram illustrating an operation of a cold air guide of the refrigerator of FIG. 1. FIG. 8 illustrates an operating state of the cold air guide when the door of the refrigerator of FIG. 1 is opened. FIG. 9 illustrates an operating state of the cold air guide when the door of the refrigerator of FIG. 1 is closed.

Referring to FIGS. 7 to 9, the cold air guide 90 may be rotationally coupled to the discharge port 72 to open or close the discharge port 72. The discharge port 72 may be formed on the top wall of the storeroom 21. The cold air guide 90 may include a cold air guide body 92 and a rotation shaft 91, and the rotation shaft 91 may be coupled to a motor 93 from which to receive a rotational force. The top guide 70 may be coupled to the motor 93. The body 92 may be the blade 92. In another embodiment of the disclosure, some of the components may be omitted. For example, the cold air guide 90 may be comprised of the rotation shaft 91 and the body 92 without the motor 93. Furthermore, the blade 92 may be replaced by a blower fan (not shown). It is not, however, limited thereto, and an extra blower fan (not shown) may be arranged in an upstream of the cold air flowing to the blade 92 to regulate a rate of flow of the cold air.

As shown in FIG. 7, the cold air guide 90 may perform an air curtain function. The cold air guide 90 may be rotated between a first position P1 at which to open the discharge port 72 to form the air curtain when the door 30 is opened, and a second position P2 at which to send the cold air supplied through the cold air supply port 62a and 63a to the second, third, and fourth spaces 21b, 21c, and 21d by controlling a degree of opening or closing of the discharge port 72 when the door 30 is closed.

As shown in FIG. 8, when the blower fan 6 is rotated when the cold air guide 90 is in the first position P1, the cold air cooled by the evaporator 3 in the cooling room 3a may be discharged down through the discharge port 72 via the rear fluid path 61 and the top fluid path 71, forming an air curtain across the open front of the storeroom 21.

In this case, to increase an amount of cold air discharged through the discharge port 72 by minimizing an amount of cold air discharged through the cold air supply port 62a and 63a, the blower fan 6 may be rotated at a higher speed than for cooling the storeroom 21.

In the storeroom cooling mode in which the blower fan 6 is rotated while the cold air guide 90 blocks the discharge port 72, the blower fan 6 may be rotated at a first speed, and in the air curtain mode in which the blower fan 6 is rotated while the cold air guide 90 opens the discharge port 72, the blower fan 6 may be rotated at a second speed higher than the first speed.

The cold air guide 90 may form an air curtain by discharging cold air to the open front of the storeroom 21 through the discharge port 72. In the air curtain mode, the cold air may be prevented from leaking out of the storeroom 21 and air outside the storeroom 21 may be prevented from flowing into the storeroom 21 when the door 30 is opened.

Using the cold air guide 90 may not only allow uniform temperature distribution in the storeroom 21 but also enable the storeroom 21 to be cooled faster.

When the user opens the door 30, wet air may flow into the storeroom 21, forming water vapor on the front cover 62. When the cold air guide 90 is used, cold air is uniformly distributed in the storeroom 21, thereby reducing an amount of water vapor formed on the front cover 62.

As shown in FIG. 9, the cold air guide 90 may be in the second position P2 to control the degree of opening or closing of the discharge port 72. In this case, when the blower fan 6 is rotated, the cold air cooled by the evaporator 3 in the cooling room 3a may pass through the rear fluid path 61 and the top fluid path 71 and may then be discharged into the storeroom 21 through the discharge port 72. Accordingly, the cold air supplied through the cold air supply port 62a and 63a may be distributed or circulated throughout the second space 21b, third space 21c, and fourth space 21d.

The discharge port 72 is opened all the time, and the cold air guide 90 may control the degree of opening or closing of the discharge port 72 to form an air curtain or to supply the cold air into a space in which the cold air supply port 62a and 63a is not formed. Accordingly, the cold air guide 90 may perform various functions.

For example, the blade 91 of the cold air guide 90 may make the discharge port 72 open all the time. It may be in the position P1 to form the air curtain when the door 30 is opened and in the position P2 to distribute the cold air in the storeroom when the door 30 is closed.

However, the blade 91 is not fixed only in the position P1 when the door is opened, nor fixed only in the position P2 when the door is closed. The blade 91 may be rotated at regular intervals to prevent formation of ice due to the cold air and moisture in the storeroom 21 and may then return to the original position P1 or P2. Furthermore, the blade 91 may be rotated to prevent the formation of ice even when the user opens the door 30 for a long time. As the blade 91 returns to the original position after being rotated at regular intervals, it may return to the original position from a position other than P1 and P2.

FIG. 10 is a schematic side cross-sectional view of a refrigerator, according to another embodiment of the disclosure.

The same features as in the aforementioned embodiment are denoted by the same reference numerals, and the overlapping description will not be repeated.

Referring to FIG. 10, the cold air guide 90 may not be provided. The cold air supplied into the first space 21a through the cold air supply port 62a and 63a may be circulated throughout the second space 21b, third space 21c, and fourth space 21d without the cold air guide 90.

Specifically, as the air velocity of the cold air supplied into the storeroom 21 may increase the higher the rotation speed of the blower fan 6 is, the cold air may be supplied into the second, third, and fourth spaces 21b, 21c, and 21d by increasing the rate of the cold air coming out of the cold air supply port 62a and 62b. With this structure, groceries not only in the first space 21a but also in the second space 21b, third space 21c, and fourth space 21d may be kept fresh.

FIG. 11 is a schematic side cross-sectional view of a refrigerator, according to another embodiment of the disclosure. FIG. 12 illustrates an operating state of a cold air guide when a door of the refrigerator of FIG. 11 is opened. FIG. 13 illustrates an operating state of the cold air guide when the door of the refrigerator of FIG. 11 is closed.

The same features as in the aforementioned embodiment are denoted by the same reference numerals, and the overlapping description will not be repeated.

Referring to FIGS. 11 to 13, the rear guide 60 may include the evaporator cover 5. Furthermore, the suction port 5a may be provided in a top portion of the storeroom 21, and the cold air supply port 62a and 63a may be provided in a bottom portion of the storeroom 21. In this case, air may flow to the evaporator 3 through the suction port 5a provided to suck air from the first space 21a, and cold air produced from the evaporator 3 may be discharged through the cold air supply port 62a and 63a connected to the fourth space 21d and supplied to the storeroom 21.

The cold air supply port 62a and 63a may be arranged at the bottom end of the evaporator cover 5. The cold air supply port 62a and 63a may be formed by being cut from the bottom end of the evaporator cover 5. Specifically, the cold air supply port 62a and 63a may be recessed inwards from the bottom end of the evaporator cover 5. Accordingly, the cold air may be supplied to the fourth space 21d. As described above, as the cold air supply port 62a and 63a is formed by being cut at an end, extra post-processing is not required after the cover is formed. Accordingly, processing and production costs may be reduced.

The discharge port 72 and the cold air guide 90 may also be arranged on the bottom of the storeroom 21. Accordingly, the cold air coming through the cold air supply port 62a and 63a formed at the bottom of the evaporation cover 5 may be distributed or circulated throughout the first space 21a, second space 21b, and third space 21c.

However, the cold air guide 90 is not an essential component to regulate cold air supplied into the storeroom through the cold air supply port 62a and 63a. Even without the cold air guide 90, the cold air may be supplied into the first space 21a, second space 21b, and third space 21c by regulating the amount of cold air coming through the cold air supply port 62a and 63a. This may keep groceries in the storeroom fresh.

The cold air guide assembly 50 may further include a bottom guide 80. The cold air in the rear cover 64 may flow to the bottom guide 80. The cold air flowing to the bottom guide 80 may pass through a third guide fluid path 81 and may then be supplied to a discharge port 82. The third guide fluid path 81 may be a bottom fluid path 81.

The bottom guide 80 may include the third guide fluid path 81 connected to the rear fluid path 61, and the discharge port 82 through which to discharge the cold air up into the storeroom 21 from the third guide fluid path 81 to supply the cold air to the first, second, and third spaces 21a, 21b and 21c of the storeroom 21.

The bottom guide 80 may also include a cover bottom 83 that separates the storeroom 21 from the third guide fluid path 81, and a pair of bottom guide walls 84 arranged to protrude down from the cover bottom 83 and face each other to form the third guide fluid path 81.

The bottom guide 80 may be coupled onto the bottom side of the inner case 21 that defines the storeroom 21, and the third guide fluid path 81 may be surrounded by the cover bottom 83, the pair of bottom guide walls 84, and the inner case 11. Alternatively, there may be an extra cover member (not shown) arranged between the bottom guide 80 and the inner case 11, in which case the third guide fluid path 81 may be surrounded by the bottom guide 80, the pair of bottom guide walls 84, and the cover member.

As shown in FIG. 12, when the blower fan 6 is rotated after the rotation shaft 91 and the body 92 of the cold air guide 90 are rotated into the first position P1 (see FIG. 7), i.e., the degree of opening is large, the cold air cooled by the evaporator 3 in the cooling room 3a may be discharged up through the discharge port 82 via the rear fluid path 61 and the third guide fluid path 81 to form an air curtain across the open front of the storeroom 21.

As shown in FIG. 13, when the blower fan 6 is rotated after the rotation shaft 91 and the body 92 of the cold air guide 90 are rotated into the second position P2 (see FIG. 7), i.e., the degree of opening is small, the cold air cooled by the evaporator 3 in the cooling room 3a may be discharged into the storeroom 21 through the cold air supply port 62a and 63a from the rear fluid path 61 and be sent into the first, second, and third spaces 21a, 21b, and 21c.

FIG. 14 illustrates a rear cover in a refrigerator, according to another embodiment of the disclosure. FIG. 15 illustrates an operating state of a rear guide when the door of the refrigerator of FIG. 14 is closed.

The same features as in the aforementioned embodiment are denoted by the same reference numerals, and the overlapping description will not be repeated.

Referring to FIGS. 14 and 15, the middle cover 63 may further include extension guide walls 66. The extension guide walls 66 may protrude backwards from the middle cover 63. The extension guide walls 66 may be connected to the middle guide walls 65. The extension guide walls 66 may extend to both sides from the middle guide walls 65. The extension guide walls 66 may allow the cold air supply port 62a and 63a to be formed at both side ends of the middle cover 63. Although not shown, as the middle cold air supply port 63a is formed at the side end of the middle cover 63, the front cold air supply port 62a is, of course, formed at the corresponding side end of the front cover 62.

The extension guide walls 66 may form an extension fluid path 67 to supply the cold air to the side ends of the rear guide 60.

In an embodiment of the disclosure, the suction port 5a may be provided in a bottom portion of the storeroom 21, and the cold air supply port 62a and 63a may discharge the cold air near to the sides of the storeroom 21. Specifically, air may flow to the evaporator 3 through the suction port 5a formed on the bottom of the storeroom 21, and cold air produced from the evaporator 3 may be discharged through the cold air supply port 62a and 63a formed at side ends of the rear guide 60 and supplied to the storeroom 21.

It is not, however, limited thereto. For example, the suction port 5a may be arranged on the top of the storeroom 21 so that the cold air may be discharged into the storeroom 21 through the cold air supply port 62a and 63a formed at sides of the rear guide 60. In this case, unlike what is shown in FIG. 13, the evaporator 3 and the blower fan 6 may be arranged in an upper portion behind the storeroom 21.

The cold air supply port 62a and 63a may be arranged at the side ends of the rear guide 60. The cold air supply port 62a and 63a may be formed by being cut from the both side ends of the rear guide 60. That is, the cold air supply port 62a and 63a may be recessed inwards from the both side ends of the rear guide 60.

Although it is shown that the cold air guide 90 is not operating, it is not limited thereto but the cold air guide 90 may be used to circulate the cold air in the storeroom 21.

Furthermore, as described above, as the cold air supply port 62a and 63a is formed by being cut at an end, extra post-processing is not required after the cover is formed. Accordingly, processing and production costs may be reduced.

Although it is shown that the cold air supply port 62a and 63a are formed as a plurality of ports at either side end, it is not limited thereto but may be formed as a single port into which a plurality of ports are connected at either side end. In this case, the cold air supply port 62a and 63a may be formed to have a longer size in the vertical direction than in the horizontal direction.

FIG. 16 illustrates an operating state of a rear guide when a door is closed in a refrigerator, according to another embodiment of the disclosure.

The same features as in the aforementioned embodiment are denoted by the same reference numerals, and the overlapping description will not be repeated.

Referring to FIG. 16, the cold air guide assembly 50 may include a rear guide 60 arranged behind the storeroom 21 and a top guide 70 arranged on top of the storeroom 21.

The rear guide 60 may include the rear fluid path 61 for guiding the cold air produced from an evaporator, and the cold air supply port 62a and 63a for supplying the cold air into the storeroom 21 from the rear fluid path 61 to cool down the storeroom 21.

The rear guide 60 may include the front cover 62 facing the storeroom 21, the middle cover 63 coupled onto the rear surface of the front cover 62, and the pair of middle guide walls 65 arranged to protrude from the middle cover 63 and face each other to form the rear fluid path 61.

The top guide 70 may also include the cover top 73 that separates the storeroom 21 from the top fluid path 71, and the pair of top guide walls 74 arranged to protrude upwards from the cover top 73 and face each other to form the top fluid path 71.

Furthermore, the top guide 70 may include a cooling discharge port 77 through which to discharge cold air into the storeroom 21 from the top fluid path 71 to cool down the storeroom 21. Accordingly, in the embodiment of the disclosure, in the mode to cool down the storeroom 21, cold air may be discharged through both the cold air supply port 62a and 63a of the rear guide 60 and the cooling discharge port 77 of the top guide 70, thereby increasing cooling efficiency of the storeroom 21.

The top guide 70 may include a detour part 78 formed by cutting off the top guide walls 74 on the cover top 73 for the cold air flowing into the top fluid path 71 to detour to the cooling discharge port 77.

There may be a plurality of detour parts 78. For example, there may be two detour parts 78 on the left and right to partition the top fluid path 71 into a center portion 71b to which the cold air flows from the rear fluid path 61, a left portion 71a formed on the left of the center portion 71b, and a right portion 71c formed on the right of the center portion 71b.

The cooling discharge port 77 may be arranged in at least one of the left portion 71a or the right portion 71c. The cold air flowing into the top fluid path 71 detours to the detour part 78 to be discharged through the cooling discharge ports 77.

In this case, even when the cold air guide 90 is not operating, the temperature in the whole storeroom may be maintained due to the cold air supplied through the cold air supply port 62a and 63a and the cooling discharge port 77. Accordingly, the refrigerator may keep the groceries fresh and have an aesthetically enhanced appearance because the cooling discharge port 77 is hardly noticeable to the user.

FIG. 17 illustrates a portion of a side cross-section of a refrigerator, according to another embodiment of the disclosure. FIG. 18 illustrates section E of the refrigerator shown in FIG. 17.

Referring to FIGS. 17 and 18, the refrigerator may further include a plurality of door guards 31. Cold air discharged from the cold air guide 90 may flow toward the door guards 31.

Although it is shown that there are the rear hole 31a and the bottom hole 31b, it is not limited to the holes but there may be a fluid path formed in an inner portion of the door guard 31.

With the rear hole 31a and the bottom hole 31b, the cold air may be uniformly distributed or circulated in the storeroom 21, thereby keeping groceries stored in the storeroom 21 fresh.

FIG. 19 illustrates a portion of a side cross-section of a refrigerator, according to another embodiment of the disclosure.

The same features as in the aforementioned embodiment are denoted by the same reference numerals, and the overlapping description will not be repeated.

Referring to FIG. 19, each of the plurality of door guards 31 may include a cold air direction guide 31c. The cold air direction guide 31c may cause the cold air discharged through the cold air supply port 62a and 63a and the discharge port 72 to be distributed in the storeroom 21.

The cold air direction guide 31c may cause the cold air discharged through the cold air supply port 62a and 63a and the discharge port 72 to flow onto the shelf 27.

The cold air direction guide 31c may have a curved shape so that the cold air flows onto the shelf 27. That is, the cold air direction guide 31c is formed as a curve for the cold air to flow onto the shelf 27. Accordingly, the groceries stored on the shelf 27 may be kept fresh.

Although it is shown that the cold air direction guide 31c is formed at the door guard 31 near a first shelf 27a, it is not limited thereto and the cold air direction guide 31c may be formed at each of the plurality of door guards 31. Depending on the shape of the cold air direction guide 31c, some of the cold air flows onto the shelf 27 and some of the cold air may flow down the storeroom 21. With this structure, the cold air may be distributed or circulated in the second space 21b, third space 21c, and fourth space 21d.

FIG. 20 illustrates a portion of a side cross-section of a refrigerator, according to another embodiment of the disclosure.

The same features as in the aforementioned embodiment are denoted by the same reference numerals, and the overlapping description will not be repeated.

Referring to FIG. 20, the refrigerator may further include a plurality of shelves 127. Each of the plurality of shelves 127 may be provided as a duct that forms a fluid path in which the cold air flows. That is, they may be formed as shelf ducts 127. In the embodiment of the disclosure, there may be a plurality of cold air supply ports 162a.

Each of the shelves 127 may include a cold air supply hole 128 and a shelf fluid path 129.

The shelf 127 may be connected to the cold air supply port 162a to receive the cold air. Specifically, the cold air produced from the evaporator 3 may flow into the shelf fluid path 129 through the rear fluid path 61 and the cold air supply port 162a. The cold air flowing into the shelf fluid path 129 may flow into the storeroom 21 through the cold air supply hole 128. The cold air supply hole 128 may be formed at the bottom of the shelf 127. The position at which the cold air supply hole 128 is formed is not limited thereto, and the cold air supply hole 128 may be formed on the top or front of the shelf 127 to supply the cold air.

Specifically, the first shelf 127a may supply the cold air that has passed through a first shelf fluid path 129a to the second space 21b. The second shelf 127b may supply the cold air that has passed through a second shelf fluid path 129b to the third space 21c. The third shelf 127c may supply the cold air that has passed through a third shelf fluid path 129c to the fourth space 21d. Furthermore, the cold air supply port 162a formed uppermost may supply the cold air into the first space 21a. In this case, the cold air may be circulated in the entire storeroom 21 without using the cold air guide 90. This may save unnecessary material costs and operation costs but may keep the groceries fresh. Furthermore, the cold air supply port 162a and the cold air supply hole 128 are hardly visible to the user, giving better aesthetic appearance.

FIG. 21 illustrates shelves and a rear guide in a refrigerator, according to another embodiment of the disclosure.

The same features as in the aforementioned embodiment are denoted by the same reference numerals, and the overlapping description will not be repeated.

Referring to FIG. 21, a front cover 160 may include a plurality of parts 161, 162, and 163. Specifically, the front cover 160 may include a first cover part 161, a second cover part 162, and a third cover part 163. The cover parts 161, 162, and 163 may be detachably coupled to one another.

The first cover part 161 may include a bottom recess 161f recessed upwards from the bottom end of the first cover part 161. The second cover part 162 may include a top recess 162g recessed downwards from the top end of the second cover part 162, and a bottom recess 162f recessed upwards from the bottom end of the second cover part 162. The third cover part 163 may include a top recess 163g recessed downwards from the top end of the third cover part 163.

The bottom recess 161f of the first cover part 161 and the top recess 162g of the second cover part 162 may form the cold air supply port 162a. The bottom recess 162f of the second cover part 162 and the top recess 163g of the third cover part 163 may also form the cold air supply port 162a. That is, in the embodiment of the disclosure, there may be a plurality of cold air supply ports 162a formed at the front cover 160.

Although it is shown that the cold air supply ports 162a are formed between the top recesses 162g and 163g and the bottom recesses 161f and 162f, it is not limited thereto. For example, the cold air supply ports 162a may include cuts formed on the outer circumference of each of the cover parts 161, 162, and 163. Specifically, the cold air supply ports 162a may be formed by being recessed upwards from the bottom ends of the respective cover parts 161, 162, and 163. Furthermore, the cold air supply ports 162a may be formed by being recessed downwards from the top ends of the respective cover parts 161, 162, and 163.

With this structure, the cold air supply ports 162a are hardly visible to the user as described above, so the refrigerator may maintain the aesthetic appearance while keeping the groceries in the storeroom 21 fresh with the cold air discharged through the cold air supply ports 162a.

Furthermore, although it is shown that the front cover 160 has three parts and there may be two cold air supply ports 162a, embodiments of the disclosure are not limited thereto and there are no limitations on the number.

The shelves 127 may be arranged in front of the respective cold air supply ports 162a. As the shelves 127 may be arranged in front of the respective cold air supply ports 162a, the cold air supply ports 162a are hardly visible to the user, so the refrigerator may maintain the aesthetic appearance and keep the groceries in the storeroom 21 fresh with the cold air discharged through the cold air supply ports 162a.

According to embodiments of the disclosure, a refrigerator having an enhanced design may be provided.

According to embodiments of the disclosure, a refrigerator having a reduced production cost may be provided.

Several embodiments of the disclosure have been described above, but a person of ordinary skill in the art will understand and appreciate that various modifications can be made without departing the scope of the disclosure. Thus, it will be apparent to those ordinary skilled in the art that the true scope of technical protection is defined by the following claims.
