By sharing cold air, the amount of cold air supplied to the freezer room is increased, and sufficient cold air is also supplied to the refrigerator room, thereby making it possible to supply sufficient cold air to the refrigerator room, freezer room, and ice-making room with a single evaporator.

Description

Technology Field

[0001] The present invention relates to a refrigerator having a refrigerator compartment and a freezer compartment that provide respective storage spaces, and an ice-making compartment provided in the refrigerator door. Background Technology

[0002] Generally, a refrigerator is a home appliance designed to store various foods for extended periods using cold air generated by the circulation of refrigerant through a freezing cycle.

[0003] Such a refrigerator is provided with one or more storage compartments partitioned from one another for freezing and storing objects. In this case, the storage compartment may be a storage compartment that opens and closes with a rotary door, or a storage compartment that allows for retrieval or storage using a drawer.

[0004] In particular, the above-mentioned storage room may include a freezer room for frozen storage of objects to be stored and a refrigerator room for refrigerated storage of objects to be stored, and may include two or more freezer rooms or two or more refrigerator rooms.

[0005] Meanwhile, recently, an ice-making compartment has been installed in the refrigerator door, allowing users to retrieve ice without opening the freezer.

[0006] That is, cold air passing through the evaporator inside the cabinet is delivered to the refrigerator door via a cold air duct for the ice-making room, and when the refrigerator door is closed, the cold air duct for the ice-making room is supplied to the ice-making room through a connecting passage provided in the refrigerator door.

[0007] In this regard, various applications are available, such as Registered Patent No. 10-1639443, Published Patent No. 10-2009-0101525, and Registered Patent No. 10-1659622.

[0008] In particular, the refrigerator having an ice-making compartment in the aforementioned refrigerator door is configured to selectively supply cold air to the refrigerator compartment, the freezer compartment, and the ice-making compartment using a single evaporator.

[0009] However, the refrigerator according to the aforementioned conventional technology has the disadvantage that it is configured to supply cold air to three spaces using a single evaporator, so the supply of cold air to the refrigerator or freezer is insufficient.

[0010] In particular, conventionally, the refrigerator-side grill fan assembly supplying cold air to the refrigerator compartment is configured to supply an equal amount of cold air to the left and right spaces within the refrigerator compartment. However, since it is configured to discharge cold air evenly to the entire area regardless of the required amount of cold air for each location—even though the amount of cold air required for each location within the refrigerator compartment varies—there was a problem of uneven temperature distribution across different parts of the refrigerator compartment.

[0011] In other words, as there was a mixture of areas where excessive cold air was provided compared to the required amount of cold air and areas where insufficient cold air was provided compared to the required amount of cold air, temperature differences between different parts of the refrigerator were inevitable.

[0012] For example, in a structure where an ice-making chamber is equipped in one of the two refrigerator doors, the refrigerator door on the side where the ice-making chamber is located (the ice-making chamber-side refrigerator door) only needs to be supplied with a relatively smaller amount of cold air compared to the opposite door due to the direct cooling effect provided by the ice-making chamber; however, because the system is configured to supply uniform cold air to the side where both refrigerator doors are located, the temperature at each location inside the refrigerator was inevitably uneven.

[0013] In addition, conventional technologies had the disadvantage that maintenance was not easy and it was difficult to standardize parts when changing refrigerator models, because the airflow path supplying cold air from the freezer to the refrigerator was configured to be a structure integrally formed with either the freezer or the refrigerator. Prior art literature

[0014] Registered Patent No. 10-1639443 Published Patent No. 10-2009-0101525 Registered Patent No. 10-1659622 The problem to be solved

[0015] The present invention has been devised to solve various problems according to the aforementioned prior art, and the objective of the present invention is to provide a new type of refrigerator that can reduce the amount of unnecessary cold air supplied to the refrigerator door on the ice-making side while ensuring that sufficient cold air is supplied to the refrigerator door on the opposite side.

[0016] In addition, another objective of the present invention is to provide a new type of refrigerator that allows cold air blown from the freezer-side grill fan assembly to be smoothly supplied to the refrigerator-side grill fan assembly, and also allows for easy maintenance.

[0017] In addition, another objective of the present invention is to provide a new type of refrigerator that maximizes the number of parts that can be used universally regardless of the refrigerator model. means of solving the problem

[0018] The refrigerator of the present invention for achieving the above-mentioned purpose is configured to provide cold air to the refrigerator compartment, the freezer compartment, and the ice-making compartment using a single evaporator. The freezer-side grill fan assembly and the refrigerator-side grill fan assembly are configured to receive cold air through a connecting flow path, and the refrigerator-side grill fan assembly is configured to supply different amounts of cold air to the two side spaces within the refrigerator compartment. As a result, sufficient cold air can be supplied to the refrigerator compartment, the freezer compartment, and the ice-making compartment using a single evaporator, while allowing the amount of cold air supplied to each part within the refrigerator compartment to vary.

[0019] In addition, the refrigerator of the present invention is configured such that the upper grill fan and the duct unit of the refrigerator compartment grill fan assembly can be separated into distinct structures. As a result, since only the duct unit needs to be replaced depending on the type of refrigerator, the upper grill fan can be used interchangeably.

[0020] In addition, the refrigerator of the present invention is provided with a blocking plate on the back surface of the duct unit. This prevents the temperature of the cold air flowing along the cold air path on the refrigerator compartment side from rising.

[0021] In addition, a cold air discharge guide is formed at the upper end of the upper grill pan of the refrigerator of the present invention. As a result, cold air flowing along the cold air path on the refrigerator compartment side can be discharged into the upper space within the refrigerator compartment.

[0022] In addition, the refrigerator of the present invention has a protrusion formed extending from the bottom of the duct unit. This allows the cold air received from the freezer-side grill fan assembly to be supplied to both refrigerator-side cold air passages formed separately on both sides of the rear of the duct unit.

[0023] In addition, the refrigerator of the present invention has a lower connecting duct installed on the protrusion of the duct unit. This allows the connecting flow path to be easily connected or disconnected.

[0024] In addition, the refrigerator of the present invention has a lower connecting duct that is detachably connected to at least one of the protrusion or the connecting passage. This makes it possible to separate the refrigerator compartment grill fan assembly from the connecting passage.

[0025] In addition, the refrigerator of the present invention is equipped with a flow path opening / closing module on the cold air outlet side of the lower connecting duct. By separating the lower connecting duct from the grill fan assembly on the refrigerator compartment side, maintenance of the flow path opening / closing module is possible.

[0026] In addition, the refrigerator of the present invention is further equipped with a lower grill pan that partitions the protrusion from the refrigerator compartment. This prevents the problem of unintended separation between the protrusion and the connecting passage.

[0027] In addition, in the refrigerator of the present invention, one end of the recovery duct for the refrigerator room is connected to the lower rear portion of the lower grill fan, and the other end is connected to the cold air inlet side of the evaporator. Thus, the cold air recovered from the refrigerator can be supplied to the refrigerator room, freezer room, or ice room after moisture is removed through the evaporator.

[0028] In addition, the refrigerator of the present invention is configured such that the cold air passage for the refrigerator chamber includes a first cold air passage for the refrigerator chamber, a second cold air passage for the refrigerator chamber, and a third cold air passage for the refrigerator chamber. As a result, cold air introduced through the third cold air passage for the refrigerator chamber can be distributed and supplied to the first cold air passage for the refrigerator chamber and the second cold air passage for the refrigerator chamber.

[0029] In addition, in the refrigerator of the present invention, the airflow opening / closing module is located within the cold air passage for the third refrigerator room. This allows for easy maintenance of the airflow opening / closing module.

[0030] In addition, the refrigerator of the present invention is configured such that the cold air passage for the second refrigerator room receives more cold air than the cold air passage for the first refrigerator room. As a result, more cold air can be supplied to the space opposite to the space where the ice-making chamber is located within the refrigerator room, and the temperature inside the refrigerator room can be maintained uniformly throughout.

[0031] In addition, the portion of the cold air outlet side of the cold air passage for the third refrigerator room of the refrigerator of the present invention is formed to be inclined or rounded so that cold air flows toward the cold air passage for the second refrigerator room. This enables the supply of more cold air to the cold air passage for the second refrigerator room.

[0032] In addition, the refrigerator of the present invention is formed such that the left and right width of the cold air passage for the second refrigerator room is wider than the left and right width of the cold air passage for the first refrigerator room, thereby enabling the supply of more cold air to the cold air passage for the second refrigerator room.

[0033] In addition, the refrigerator of the present invention is formed so that more cold air is discharged through the second middle compartment cold air outlet formed in the second refrigerator room cold air flow path compared to the first middle compartment cold air outlet formed in the first refrigerator room cold air flow path.

[0034] In addition, the refrigerator of the present invention is additionally provided with an upper connecting duct. This allows cold air flowing along the cold air passage for the refrigerator room to be directly supplied to the front space within the refrigerator room.

[0035] In addition, the refrigerator of the present invention has a cold air outlet formed on the upper surface of the freezer-side grill fan assembly. By doing so, cold air can be supplied to the refrigerator-side grill fan assembly through a connecting flow path connected to the cold air outlet.

[0036] In addition, the refrigerator of the present invention is formed such that the cold air outlet gradually widens as it extends upward, thereby enabling it to provide a sufficient amount of cold air to the grill fan assembly in the refrigerator compartment. Effects of the invention

[0037] As described above, the refrigerator of the present invention has the effect of allowing the cold air passage for the freezer and the cold air passage for the ice-making room to be shared with each other by providing a shared air passage, thereby ensuring that sufficient cold air is supplied to the freezer even when the freezer fan and the ice-making fan operate simultaneously, and also preventing the phenomenon of cold air flowing back from the freezer when the ice-making fan operates alone.

[0038] In addition, the refrigerator of the present invention is formed such that the open portion of the cold air outlet side of the shared air passage does not face the refrigeration fan module, so the cold air provided from the cold air passage for the ice-making room through the shared air passage does not interfere with the cold air flow flowing through the cold air passage for the freezer room.

[0039] In addition, the refrigerator of the present invention has a lower shared passage formed on the bottom surface (second perimeter passage rib) of the installation area of ​​the ice-making fan module, and an additional extension passage formed in the shroud extending to the lower compartment within the freezer, thereby enabling sufficient cold air to be supplied to the lower compartment within the freezer. In particular, by additionally forming a drain hole in the extension passage and forming the lower shared passage penetrating between the second perimeter passage rib and the wall of the shroud, the refrigerator has the effect of allowing condensation or moisture present at the installation area of ​​the ice-making fan module to be smoothly discharged to the outside of the freezer.

[0040] In addition, the refrigerator of the present invention has the effect of improving freezing efficiency by ensuring that cold air flowing through the cold air passage for the freezer is supplied differently to each part of the freezer as guide ribs are formed on each wall surface within the cold air passage for the freezer.

[0041] In addition, the refrigerator of the present invention is configured to supply cold air to the cold air passage for the refrigerator of the grill fan assembly on the refrigerator side through a cold air outlet formed on the upper wall of the cold air passage for the freezer and a connecting duct connected thereto, so it has the effect of enabling selective cold air supply to the refrigerator, freezer, and ice-making room with a single evaporator.

[0083] The above cold air duct (51) for the ice making room is a duct that guides the supply of cold air received from the freezer-side grill fan assembly (2) to the ice making room (21).

[0084] One end (51a) of the cold air duct (51) for the ice-making room is installed to pass through and connect to one side of the freezer-side grill fan assembly (2) (the side where the refrigerator door with the ice-making room is located, which is the right side in the drawing when viewed from the rear). That is, the outlet through which the cold air of the cold air flow path (213) for the ice-making room flows out is formed to open to one side between the grill fan (220) and the shroud (210) forming the freezer-side grill fan assembly (2), so that the cold air blown by the ice-making fan module (230) can flow smoothly without a sudden change in direction. This is as illustrated in the attached FIGS. 9 and 12.

[0085] In addition, the other end (51b) of the cold air duct (51) for the ice making room is installed to penetrate the side wall of the inner case (10b) for the refrigerator room and be exposed inside the refrigerator room (11).

[0086] At this time, the other end (51b) of the cold air duct (51) for the ice room is configured to align with the supply guide duct (21a) provided in the first refrigerator door (20a) when the first refrigerator door (20a) in which the ice room (21) is provided is closed, and to supply cold air to the supply guide duct (21a). The supply guide duct (21a) is formed to extend to the ice room (21) and to supply cold air to the ice room (21).

[0087] In addition, the first refrigerator door (20a) is further provided with a recovery guide duct (21b), and one end of the recovery guide duct (21b) is connected to the ice-making room (21), while the other end is extended to the bottom side of the side wall of the first refrigerator door (20a) to guide the flow of recovered cold air passing through the ice-making room (21). This is illustrated in the attached FIG. 12.

[0088] Additionally, a recovery duct (52) for an ice-making room is provided between the outer case (10a) of the cabinet (10) and one of the side walls of the two inner cases (10b, 10c).

[0089] The above ice-making room recovery duct (52) is a duct that guides cold air passing through the ice-making room (21) to be recovered into the freezer room (12).

[0090] One end (52a) of the above-mentioned recovery duct (52) for the ice-making room is installed to penetrate the side wall of the inner case (10b) for the refrigerator room and be exposed inside the refrigerator room (11). At this time, the one end (52a) of the above-mentioned recovery duct (52) for the ice-making room is configured so that the other end of the recovery guide duct (21b) aligns with the closing operation of the refrigerator room door (20a) in which the ice-making room (21) is provided. This is as illustrated in the attached FIG. 2 and FIG. 12.

[0091] In addition, the other end (52b) of the recovery duct (52) for the ice making room is installed to be exposed inside the freezer room (12) by passing through a through hole (12a) (see attached FIG. 6 and FIG. 10) formed in the side wall of the inner case (10c) for the freezer room.

[0092] The other end (52b) of the above ice-making room recovery duct (52) is configured to be located at the rearmost side of the lower compartment space within the freezer room (12).

[0093] In particular, it is more preferable that the through hole (12a), where the other end (52b) of the ice-making room recovery duct (52) is located, be positioned as close as possible to the cold air intake side (the side where cold air recovered from the freezer to the evaporator is sucked) of the freezer-side grill fan assembly (2). That is, the cold air recovered from the ice-making room recovery duct (52) is allowed to flow directly toward the evaporator (40) while minimizing its impact on the temperature and humidity inside the freezer (12).

[0094] It is more preferable that the through hole (12a) where the other end (52b) of the ice-making room recovery duct (52) is located is positioned parallel to the side of the first suction guide (224a) formed in the freezer-side grill fan assembly (2) on one of the side walls of the freezer-side inner case (10c).

[0095] In particular, the other end (52b) of the ice-making room recovery duct (52) (or the through hole (12a) where the other end is located) is formed in a triangular structure that gradually narrows toward the bottom and is formed to open into the lower compartment of the freezer room (12).

[0096] That is, if the cold air discharge side portion (or through hole) of the ice-making room recovery duct (52) is formed to have a long horizontal structure, it can affect the temperature inside the freezer room (12) to that extent. However, the cold air discharge side portion (or through hole) of the ice-making room recovery duct (52), which is formed in a triangular structure as in the embodiment of the present invention, has a long vertical structure while taking into account the shape of the machine room (15), so the effect on the temperature inside the freezer room (12) is minimal.

[0097] Additionally, the refrigerator-side grill fan assembly (1) is configured to supply cold air received from the freezer-side grill fan assembly (2) through the connecting passage (54) to each part within the refrigerator room (11), and the freezer-side grill fan assembly (2) is configured to selectively supply heat-exchanged cold air to the refrigerator room (11), the freezer room (12), or the ice-making room (21) via the evaporator (40).

[0098] At this time, the connecting passage (54) is configured to connect the lower central portion of the refrigerator-side grill fan assembly (1) and the upper central portion of the freezer-side grill fan assembly (2). This is as illustrated in the attached FIGS. 9, 11, and 14.

[0099] The above connecting channel (54) can be formed as a block with a channel formed inside.

[0100] Of course, although not shown, the above connecting channel (54) may be formed as a hollow tube (duct) or as a flexible material such as a hose.

[0101] Additionally, a flow path opening / closing module (60) may be provided in at least one part of the above-mentioned refrigerator-measuring grill fan assembly (1) or the above-mentioned connecting flow path part (54).

[0102] The above-mentioned airway opening / closing module (60) serves to selectively block the cold air of the cold air passage (214) for the freezer room that flows in through the above-mentioned connecting airway section (54). That is, selective cold air supply can be provided to the cold air passage (121) for the freezer room of the above-mentioned grill fan assembly (1) by the above-mentioned airway opening / closing module (60).

[0103] At this time, the above-mentioned airway opening / closing module (60) may be provided on the cold air inlet side of the cold air passage (121) for the refrigerator room. That is, by providing the airway opening / closing module (60) to the refrigerator room side grill fan assembly (1), assembly and maintenance can be easily performed.

[0104] As shown in the attached FIG. 8, the Euro opening / closing module (60) is configured to include a damper case (61), an opening / closing damper (62), and a damper operating part (63).

[0105] Here, the damper case (61) is installed in the cold air passage for the refrigerator and is formed as a square frame structure with a through hole (61a) formed on the inside, the opening / closing damper (62) is installed inside the damper case (61) and is configured to open / close the through hole (61a), and the damper operating part (63) is configured to operate the opening / closing damper (62).

[0106] At this time, the damper operating part (63) may be a motor, and the opening / closing damper (62) may be formed as a plate that is axially coupled to the motor and rotates to block or open the through hole (61a).

[0107] Of course, although not shown, the above-mentioned Euro opening / closing module (60) may be configured to forcibly block or open the passage through which cold air passes by means of a solenoid or cylinder, and may also be configured with various other structures.

[0108] Meanwhile, the refrigerator according to the embodiment of the present invention is provided with an improved refrigerator compartment grill fan assembly (1).

[0109] That is, a conventional general refrigerator compartment grill fan assembly is configured to supply a uniform amount of cold air to both the left-right and upper-lower spaces within the refrigerator compartment (11). Accordingly, in the case of a refrigerator equipped with an ice-making chamber (21) in the refrigerator door (20a), there was a problem in that the temperature of each part inside the refrigerator compartment (11) was not uniform and a severe temperature deviation occurred.

[0110] Accordingly, the refrigerator compartment-side grill fan assembly (1) of the refrigerator according to an embodiment of the present invention is configured to supply more cold air to the space on the side where the second refrigerator door (20b) is located compared to the space on the side where the first refrigerator door (20a) is located among the two side spaces within the refrigerator compartment (11).

[0111] That is, the first refrigerator door (20a) is provided with an ice-making room (21), and considering that the cold air supplied to the ice-making room (21) is cold air from the freezer room (12) side, which has a lower temperature than the cold air inside the refrigerator room (11), the ambient temperature of the ice-making room (21) also has a lower temperature than the temperature inside the refrigerator room (11). Accordingly, even if the cold air from the refrigerator room (11) is not sufficiently supplied to the side where the ice-making room (21) is located, it is maintained at a lower temperature range compared to other parts, so that more cold air can be supplied to the side where the second refrigerator door (20b) is located, thereby ensuring that the temperature of the entire refrigerator room is maintained uniformly.

[0112] Of course, since one side of the refrigerator (11) is smaller than the other side of the space occupied by the ice-making room (21), the amount of cold air supplied to the one side of the space is less than the amount of cold air provided to the other side of the space, so the refrigeration of the stored items can be carried out smoothly.

[0113] Below, an example of the specific structure of the refrigerator compartment grill pan assembly (1) according to the embodiment of the present invention described above will be explained with reference to the attached FIGS. 15 to 25.

[0114] Figure 15 attached is a front perspective view illustrating a refrigerator compartment grill pan assembly according to an embodiment of the present invention, and Figure 16 is a rear perspective view illustrating a refrigerator compartment grill pan assembly according to an embodiment of the present invention.

[0115] In addition, the attached FIG. 17 is a front view illustrating a refrigerator compartment grill fan assembly according to an embodiment of the present invention, and FIG. 18 is a rear view illustrating a refrigerator compartment grill fan assembly according to an embodiment of the present invention.

[0116] As shown in these drawings, the refrigerator compartment grill fan assembly (1) is configured to include an upper grill fan (110) and a duct unit (120), and each component is described as follows.

[0117] First, the upper grill pan (110) is described.

[0118] The upper grill pan (110) above is a part that forms the front of the refrigerator-measured grill pan assembly (1).

[0119] The front of this upper grill pan (110) is provided as the rear wall of the refrigerator (11) when viewed from the front.

[0120] A plurality of cold air discharge ports (111, 112a, 112b) are formed in the upper grill pan (110) (see FIG. 15 and FIG. 17).

[0121] The above cold air outlets (111, 112a, 112b) include a cold air outlet (111) for the upper compartment that supplies cold air to the upper compartment of the refrigerator room (11) and a cold air outlet (112a, 112b) for the middle compartment that supplies cold air to the middle compartment of the refrigerator room (11).

[0122] Here, the upper cold air discharge port (111) is configured to guide cold air to be discharged along the upper wall surface inside the refrigerator room (11), and is formed at the upper end of the upper grill pan (110).

[0123] In particular, a cold air discharge guide (110a) is formed at the upper end of the upper grill pan (110) to guide the flow direction of cold air discharged through the cold air discharge port (111) for the upper compartment. This cold air discharge guide (110a) is formed to be inclined forward or rounded as it approaches the upper end (see attached FIG. 16 and FIG. 19).

[0124] The above-mentioned cold air outlets (112a, 112b) for the middle compartment are provided in two, and each of the above-mentioned cold air outlets (112a, 112b) is formed to be positioned symmetrically on both sides when viewed with respect to the central part of the refrigerator room (11).

[0125] At this time, one of the two cold air outlets for the middle compartment (112a, 112b) (hereinafter referred to as the “first cold air outlet for the middle compartment”) (112a) is located on the side facing the first refrigerator door (20a) where the ice-making room (21) is located, and the other cold air outlet for the middle compartment (hereinafter referred to as the “second cold air outlet for the middle compartment”) (112b) is located on the side facing the second refrigerator door (20b) where the ice-making room (21) is not located.

[0126] The two cold air outlets (112a, 112b) for the above-mentioned middle compartments are formed identically to each other.

[0127] Of course, although not shown, the left and right widths of the two cold air outlets (112a, 112b) for the middle compartments may be formed differently. However, if the left and right widths of the two cold air outlets (112a, 112b) for the middle compartments are formed differently, it may cause dissatisfaction among users. That is, if the refrigerator-side grill fan assembly (1) forming the rear wall of the refrigerator compartment (11) is formed in an asymmetrical shape that is not symmetrical, users may suspect a defect in the product due to the asymmetrical shape or have dissatisfaction with the design.

[0128] Considering this, it is preferable that the two cold air outlets (112a, 112b) for the middle compartments be formed identically.

[0129] In addition, non-use cold air outlets (113a, 113b) may be further formed in the upper grill pan (110).

[0130] The above-mentioned non-use cold air outlets (113a, 113b) are cold air outlets with their backs blocked so that actual cold air discharge does not occur, and are located at the bottom of the above-mentioned two middle compartment cold air outlets (112a, 112b).

[0131] Next, the above duct unit (120) will be described.

[0132] The above duct unit (120) is a part that guides the flow of cold air and is provided on the back surface of the upper grill pan (110) as shown in the attached FIGS. 16 and FIGS. 18 to 20.

[0133] The above duct unit (120) is closely coupled to the back surface of the above upper grill (110), and the coupling may include screw coupling, bonding coupling, press-fit coupling, fusion coupling, etc.

[0134] In addition, two cold air inlets (122a, 122b) for the middle section that penetrate the front and rear are formed on both sides of the duct unit (120) respectively (see attached FIG. 19 and FIG. 20).

[0135] These two cold air inlets (122a, 122b) for the middle compartments include a first cold air inlet (122a) formed to be positioned to coincide with the first cold air outlet (112a) for the middle compartment of the upper grill pan (110), and a second cold air inlet (122b) formed to be positioned to coincide with the second cold air outlet (112b) for the middle compartment of the upper grill pan (110).

[0136] The above two cold air inlets (122a, 122b) for the middle compartments may be formed with the same size as the above two cold air outlets (112a, 112b) for the middle compartments, or may be formed with different sizes.

[0137] In addition, a cold air passage (124) for a first refrigerator room and a cold air passage (125) for a second refrigerator room are each formed in a recess on the back surface of the duct unit (120).

[0138] The above two cold air passages (124, 125) for the refrigerator room are passages that guide cold air supplied from the lower end of the duct unit (120) to flow up to the upper end.

[0139] Here, the first cold air passage (124) for the first refrigerator is a passage formed on one side (right side when viewed from the rear view of FIG. 20) facing the first refrigerator door (20a) where the ice-making room (21) is located, when viewed from the central part of the duct unit (120), and the second cold air passage (125) for the second refrigerator is a passage formed on the other side (left side when viewed from the rear view of FIG. 20) facing the second refrigerator door (20b) where the ice-making room (21) is not located.

[0140] At this time, the upper end of the first cold air passage (124) for the refrigerator is formed to be open upward by penetrating the upper surface of the duct unit (120). The upper end of the first cold air passage (124) for the refrigerator can be positioned to coincide with one end of the cold air discharge port (111) for the upper compartment of the upper grill pan (110).

[0141] In addition, the first cold air passage (124) is formed to be in communication with the first cold air discharge port (112a) for the middle compartment, and the second cold air passage (125) is formed to be in communication with the second cold air discharge port (112b) for the middle compartment.

[0142] In particular, the first cold air passage (124) is formed to partially connect with the first cold air inlet (122a) for the middle compartment located on the corresponding side, and the second cold air passage (125) is formed to fully connect with the second cold air inlet (122b) for the middle compartment located on the corresponding side. That is, the connecting portion between the second cold air passage (125) for the second cold room and the second cold air outlet (112b) for the middle compartment is formed to be larger than the connecting portion between the first cold air passage (124) for the cold room and the first cold air outlet (112a) for the middle compartment.

[0143] As a result, the amount of cold air supplied to the two side spaces inside the refrigerator (11) is different, and in particular, since more cold air is supplied to the opposite side space compared to the space where the ice-making room (21) is located, the temperature difference between each part inside the refrigerator (11) can be minimized.

[0144] That is, among the two side spaces within the refrigerator (11), the space on the side where the ice-making room (21) is located is provided to be narrower than the space on the opposite side by the thickness of the ice-making room (21), and the temperature inside the ice-making room (21) is lower than the temperature inside the refrigerator (11). Considering this, more cold air is supplied to the space on the two side spaces within the refrigerator (11) where the ice-making room (21) is not located, thereby allowing the entire area inside the refrigerator (11) to have a uniform temperature range.

[0145] Meanwhile, the left and right width of the second cold air passage (125) can be formed wider than the left and right width of the first cold air passage (124).

[0146] That is, a larger amount of cold air can be supplied to the cold air passage (125) for the second refrigerator room, and thereby a larger amount of cold air can be supplied to the space on the side of the refrigerator room (11) where the ice-making room (21) is not located, through the cold air discharge port (112b) for the second middle compartment which is connected to the cold air passage (125) for the second refrigerator room.

[0147] In addition, a protrusion (130) is formed at the bottom of the duct unit (120) that protrudes further downward from the bottom surface of the upper grill pan (110).

[0148] At this time, a third cold air passage (131) for a third refrigerator room is formed in the protrusion (130) to guide the flow of cold air from the freezer-side grill fan assembly (2) received through the connecting passage (54), and the lower ends of the first cold air passage (124) and the second cold air passage (125) for a second refrigerator room formed on the back surface of the duct unit (120) are formed to meet the third cold air passage (131) of the protrusion (130).

[0149] In particular, the cold air passage (131) for the third refrigerator is configured to supply more cold air to the cold air passage (125) for the second refrigerator compared to the cold air passage (124) for the first refrigerator.

[0150] To this end, the cold air outlet side portion of the cold air passage (131) for the third refrigerator room may be formed with a slope or a rounded shape so that cold air flows in the same direction as the slope formed by the cold air inlet side portion of the cold air passage (125) for the second refrigerator room.

[0151] At this time, it is preferable that the cold air passage (124) for the first refrigerator room be formed in a direction different from the cold air passage (131) for the third refrigerator room and the cold air passage (125) for the second refrigerator room, with an incline or a rounded shape.

[0152] That is, as described above, by making the cold air supplied to the second cold air channel (125) through the third cold air channel (131) greater than the cold air supplied to the first cold air channel (124), more cold air can be supplied to the non-ice-making room side space (the space on the side where the ice-making room is not located) within the refrigerator room (11).

[0153] In addition, a lower connecting duct (132) may be installed at the lower end of the protrusion (130).

[0154] The lower connecting duct (132) above is the part where the connecting flow path (54) is connected.

[0155] Of course, the connecting channel (54) may also be configured to be directly connected to the third cold air channel (131) for the third refrigerator room of the protrusion (130). However, a coupling structure in which the connecting channel (54) is simply inserted into the third cold air channel (131) for the third refrigerator room may be easily separated when vibration, external impact, or shaking of the refrigerator occurs, and there is a risk of cold air leakage because airtightness is not ensured. Furthermore, if it is firmly coupled to prevent such concerns, there is difficulty in separating it for maintenance.

[0156] Considering this, it is more desirable to provide an additional lower connecting duct (132) to enable a solid and airtight connection of the connecting passage (54) while also making maintenance easier.

[0157] At this time, the lower connecting duct (132) is formed to protrude such that one end is inserted and coupled to the cold air inlet side of the cold air passage (131) for the third refrigerator room, and the other end is inserted and coupled into the connecting passage section (54).

[0158] In particular, the lower connecting duct (132) may be detachably connected to both the protrusion (130) and the connecting passage (54). This makes it possible to separate the refrigerator-side grill fan assembly (1) from the connecting passage (54). Of course, the lower connecting duct (132) may also be configured to be detachably connected to only one of the protrusion (130) or the connecting passage (54).

[0159] The Euro opening / closing module (60) may be provided on the cold air outlet side of the lower connecting duct (132) within the cold air passage (131) for the third refrigerator room of the protrusion (130).

[0160] In addition, the duct unit (120) may be provided with an installation part (126) (see attached FIGS. 16 and FIGS. 18 to 20) for installing an air purification module (170) (see attached FIGS. 15 and FIGS. 17).

[0161] The above air purification module (170) is configured to inhale cold air from the refrigerator room (11), remove odor components, and then recirculate it to the refrigerator room (11).

[0162] Although not illustrated in detail, this air purification module (170) may be configured to include a suction fan and a filter. That is, it may be configured to suck in cold air from inside the refrigerator room through the operation of the suction fan, filter it, and then recirculate it to the refrigerator room (11), thereby deodorizing odor components and removing various contaminants inside the refrigerator room (11).

[0163] The above installation part (126) is located at the upper central portion of the duct unit (120) (between the cold air passage for the first refrigerator room and the cold air passage for the second refrigerator room) and is formed as a hole that is open in the front and back so that the air purification module (170) can be mounted.

[0164] In addition, a recovery channel (127) is formed on the back of the duct unit (120) to supply the cold air that has passed through the installation part (126) back into the refrigerator room (11), and a communication hole (127a) is formed in the recovery channel (127) to communicate with the middle compartment space and the lower compartment space within the refrigerator room (11).

[0165] In addition, a blocking plate (140) may be further provided on the back of the duct unit (120).

[0166] The above blocking plate (140) is a portion provided to cover the cold air passage (124, 125) formed on the back surface of the duct unit (120).

[0167] In particular, the above-mentioned blocking plate (140) is formed of an insulating material. This prevents heat loss due to heat exchange with the outside air while cold air flows along the two cold air passages (124, 125) for the refrigerator.

[0168] At this time, the insulation material can be provided in various forms, such as styrofoam, fiber, wood, rubber, and synthetic resin.

[0169] Meanwhile, the above duct unit (120) may further be provided with an upper connecting duct (128) (see attached Figs. 10 to 18).

[0170] The upper connecting duct (128) is a duct provided to transfer a portion of the cold air that has flowed upward along the first cold air passage (124) or the second cold air passage (125) to other parts up to the upper end.

[0171] That is, by additionally connecting a guide duct (129) to the upper connecting duct (128), cold air can be supplied directly up to the part where the guide duct (129) is connected. This is as illustrated in the attached FIG. 9.

[0172] At this time, the rear end of the guide duct (129) is connected to the upper connecting duct (128), and the front end is connected to penetrate the upper front wall of the refrigerator room (11) and be exposed into the refrigerator room (11).

[0173] In particular, the upper connecting duct (128) described above may be configured to receive a portion of cold air from the cold air passage (125) for the second refrigerator room.

[0174] That is, a branch passage (125c) is additionally formed in the cold air passage (125) for the second refrigerator room, and the upper connecting duct (128) is connected to the cold air discharge side of the branch passage (125c). At this time, a branch guide (125d) for forming the branch passage (125c) may be formed in the cold air passage (125) for the second refrigerator room. This is as illustrated in the attached FIGS. 16 to 18.

[0175] In addition, a lower grill pan (150) (see attached FIGS. 22 to 26) may be further provided in front of the protrusion (130) on the bottom surface of the upper grill pan (110).

[0176] The lower grill pan (150) is configured to form the lower portion of the front wall of the refrigerator room grill pan assembly (1) as shown in the attached FIG. 5, and serves to block the protrusion (130) connected at that location from being exposed to the refrigerator room (11).

[0177] A cold air recovery port (151) that is open into the refrigerator chamber (11) is formed at the lower end portion of the lower grill pan (150) (see attached FIG. 5 and FIG. 22 to 26).

[0178] That is, the cold air flowing inside the refrigerator room (11) is discharged to the rear of the inner case (10b) for the refrigerator room through the cold air recovery port (151).

[0179] At this time, the recovery duct (53) for the refrigerator is installed such that one end covers the area where the cold air recovery port (151) is formed on the back of the lower grill pan (150), and the other end is installed to be connected to the cold air inlet side of the evaporator (40).

[0180] In addition, the refrigerator according to an embodiment of the present invention is provided with an improved freezer-measuring grill pan assembly (2).

[0181] This freezer-side grill fan assembly (2) has a cold air passage (213) for the ice-making room and a cold air passage (214) for the freezer room that guide the flow of cold air by the operation of each of the two fan modules (230, 240). The two cold air passages (213, 214) are configured to share cold air with each other, and the cold air passage for the freezer room is connected to a connecting passage so as to supply cold air to the refrigerator-side grill fan assembly.

[0182] Below, an example of the specific structure of the above-mentioned freezer-measuring grill pan assembly (2) will be described in more detail with reference to the attached FIGS. 26 to 35.

[0184] Additionally, the attached FIG. 30 is a front view illustrating a freezer-side grill fan assembly of a refrigerator according to an embodiment of the present invention, FIG. 31 is a rear view illustrating a freezer-side grill fan assembly of a refrigerator according to an embodiment of the present invention, FIG. 32 is a rear view illustrating a grill fan among the freezer-side grill fan assembly of a refrigerator according to an embodiment of the present invention, and FIG. 33 is a front view illustrating a shroud among the freezer-side grill fan assembly of a refrigerator according to an embodiment of the present invention.

[0185] As shown in these drawings, the freezer-side grill pan assembly (2) is configured to include a shroud (210) and a grill pan (220).

[0186] Here, the shroud (210) is a portion forming the rear wall of the freezer-side grill pan assembly (2), and the grill pan is a portion forming the front wall of the freezer-side grill pan assembly (2).

[0187] At this time, the evaporator (40) is located at the rear of the freezer room (12) among the rear wall surfaces (rear wall surfaces within the inner case) of the cabinet (10), and the shroud (210) is located in front of the evaporator (40).

[0188] Additionally, a first inlet hole (211a) and a second inlet hole (211b) are formed through the shroud (210).

[0189] The two inlet holes (211a, 211b) are holes formed to allow cold air, which has been heat-exchanged while passing through the evaporator (40) located at the rear of the freezer (12), to flow into the space between the grill fan (220) and the shroud (210).

[0190] A refrigeration fan module (240) is installed in the portion of the front surface of the above shroud (210) where the first inlet hole (211a) is formed, and an ice-making fan module (230) is installed in the portion where the second inlet hole (211b) is formed.

[0191] In particular, the first inlet hole (211a) is formed at the upper central portion of the shroud (210), and the second inlet hole (211b) is formed on one side of the first inlet hole (211a).

[0192] In addition, a cold air passage (213) for an ice-making room and a cold air passage (214) for a freezer room are formed on the front of the shroud (210), respectively (see attached FIG. 27 and FIG. 33).

[0193] The above-mentioned cold air passage (213) for the ice-making room is a passage that guides cold air flowing between the shroud (210) and the grill pan (220) through the second inlet hole (211b) to flow to the connection part with the cold air duct (51) for the ice-making room, and the above-mentioned cold air passage (214) for the freezer room is a passage that guides cold air flowing between the shroud (210) and the grill pan (220) through the first inlet hole (211a) to the upper, middle, and lower compartments of the freezer room (12), respectively.

[0194] The above cold air passage (214) for the freezer and the cold air passage (213) for the ice making room may be formed by recessing at least one of the front surface of the shroud (210) or the back surface of the grill pan (220), or may be formed by protruding a separate rib on the front surface of the shroud (210) or the back surface of the grill pan (220).

[0195] Along with this, a cold air outlet (214e) is formed on the upper wall surface (214a) of the shroud (210).

[0196] The above cold air outlet (214e) is formed to be located directly above the refrigeration fan module (240) as an open portion that communicates with a part of the cold air passage (214) for the freezer. One end of the connecting passage (54) is connected to the above cold air outlet (214e).

[0197] In particular, the above cold air outlet (214e) is formed to gradually slope or round toward the rear of the freezer-side grill fan assembly (2) as it extends upward from the area where the first inlet hole (211a) is formed (the area where the freezer fan module is located). As a result, the cold air outlet (214e) is formed such that the opening becomes progressively larger toward the cold air outflow side, thereby enabling a sufficiently large amount of cold air to be supplied to the refrigerator (11).

[0198] In addition, the cold air passage (214) for the freezer and the cold air passage (213) for the ice-making room are formed to be separated from each other by the passage ribs (213a, 213b) (shown in FIG. 20). That is, the passage ribs (213a, 213b) are formed across the front of the shroud (210) between the cold air passage (214) for the freezer and the cold air passage (213) for the ice-making room so that the cold air passage (214) for the freezer and the cold air passage (213) for the ice-making room can be separated from each other.

[0199] The above-mentioned uro-ribs (213a, 213b) are configured to include a first circumferential uro-rib (213a) and a second circumferential uro-rib (213b) formed along the circumference of the second inlet hole (211b).

[0200] The area where the second inlet hole (211b) is formed by the two circumferential air passage ribs (213a, 213b) can be partitioned from the cold air passage (214) for the freezer, and the cold air passing through the second inlet hole (211b) can be blown to the cold air duct (51) for the ice-making room along the cold air passage (213) for the ice-making room formed by the two air passage ribs (213a, 213b).

[0201] The first circumferential flow path rib (213a) is formed to cross between the first inlet hole (211a) and the second inlet hole (211b) on the front of the shroud (210). That is, as the first circumferential flow path rib (213a) is formed to block the space between the ice-making fan module (230) and the refrigeration fan module (240), the cold air provided from the refrigeration fan module (240) is prevented from being discharged directly to the cold air outlet side of the cold air flow path (213) for the ice-making room.

[0202] In addition, the first circumferential duct rib (213a) is formed in a rounded shape to surround a portion of the circumference of one side (the side where the refrigeration fan module is located) of the ice-making fan module (230). As a result, the cold air radiated while rotating in the circumferential direction by the operation of the ice-making fan module (230) can be guided by the first circumferential duct rib (213a) and flow toward the connection point with the cold air duct (51) for the ice-making room.

[0203] Additionally, the second circumferential urorib (213b) is formed to surround the lower circumference of the area where the ice-making fan module (230) is installed on the front of the shroud (210). That is, the lower portion from the central portion between the ice-making fan module (230) and the refrigeration fan module (240) is separated from each other by the second circumferential urorib (213a).

[0204] In addition, the second circumferential side Eurorib (213b) is formed in a rounded shape to wrap around the bottom side circumference of the ice-making fan module (230).

[0205] Additionally, the two circumferential flow ribs (213a, 213b) are formed spaced apart from each other, thereby forming an upper shared flow path (215a) between the end of the first circumferential flow rib (213a) and the end of the second circumferential flow rib (213b).

[0206] At this time, the cold air passage (214) for the freezer and the cold air passage (213) for the ice-making room share cold air with each other through the upper shared passage (215a). That is, when the ice-making fan module (230) is in operation, a portion of the cold air flowing through the cold air passage (213) for the ice-making room is supplied to the cold air passage (214) for the freezer room through the upper shared passage (215a), thereby enabling sufficient cold air to be supplied to the freezer room (12) or the refrigerator room (11).

[0207] In particular, the second circumferential channel rib (213b) is positioned to surround the outer edge of the lower end of the first circumferential channel rib (213a), so that the upper shared channel (215a) formed between the two circumferential channel ribs (213a, 213b) discharges cold air toward the upper space within the cold air channel (214) for the freezer.

[0208] In addition, a lower shared channel (215b) may be formed at the bottom of the second circumferential channel rib (213b).

[0209] The above lower shared channel (215b) is a channel formed to guide the supply of cold air to the bottom side within the cold air channel (214) for the freezer, and when the ice-making fan module (230) is operated alone, it supplies cold air to the freezer (12) to eliminate the pressure difference between the cold air channel (214) for the freezer (or freezer) and the cold air channel (213) for the ice-making room.

[0210] Of course, the condensate present in the cold air passage (213) for the ice-making room can be discharged to the outside through the lower shared passage (215b), thereby preventing operational failures such as freezing of the ice-making fan module (230).

[0211] In addition, the grill pan (220) has a plurality of cold air outlets (221, 222, 223) for a freezer.

[0212] The above cold air outlets (221, 222, 223) for the freezer include a cold air outlet (221) for the upper compartment that discharges cold air into the upper compartment of the freezer (12), a cold air outlet (222) for the middle compartment that discharges cold air into the middle compartment of the freezer (12), and a cold air outlet (223) for the lower compartment that discharges cold air into the lower compartment of the freezer (12). This is as illustrated in the attached FIGS. 30 and 32.

[0213] Additionally, the grill pan (220) is further provided with suction guides (224a, 224b) that guide the flow of recovered cold air that has flowed through the freezer (12). At this time, the suction guides (224a, 224b) are formed at the lower end of the grill pan (220) so that the cold air recovered after circulating inside the freezer (12) flows into the lower end of the evaporator (40).

[0214] At this time, the suction guides (224a, 224b) are formed to be inclined at an angle (or round) that is the same (or similar) to the wall surface forming the rear bottom of the freezer (12) as they extend toward the lower end. That is, the cold air flowing along the bottom surface inside the freezer (12) is guided by the suction guides (224a, 224b) and flows smoothly to the lower end of the evaporator (40).

[0215] In particular, the suction guides (224a, 224b) are configured to include a first suction guide (224a) provided on the side where the other end (52b) of the ice-making room recovery duct (52) is located, based on the central portion of the grill fan (220) among the lower ends of the grill fan (220), and a second suction guide (224b) provided on the side opposite to the first suction guide (224a), based on the central portion of the grill fan (220). That is, cold air flowing through one side space (the space connected to the other end of the ice-making room recovery duct) within the freezer room (12) is recovered through the first suction guide (224a), and cold air flowing through the other side space within the freezer room (12) is recovered through the second suction guide (224b).

[0216] In the following, the temperature control process for the refrigerator room, freezer room (12) and ice room (21) of the refrigerator according to the embodiment of the present invention described above will be explained in more detail.

[0217] First, the process for controlling the temperature of the refrigerator room (11) will be explained with reference to the attached FIGS. 36 to 39.

[0218] The temperature control of the above refrigerator room (11) is performed by the operation of the refrigeration fan module (240), the compressor (not shown), and the flow path opening / closing module (60).

[0219] That is, when the Euro opening / closing module (60) operates to open the connecting air passage (54) and the cold air passage (121) for the refrigerator room to each other (see the state in attached FIG. 8), operation for temperature control of the refrigerator room (11) is performed by the rotation of the refrigeration fan module (240) by power supply to the refrigeration fan module (240) and the heat exchange operation of the evaporator (40) by the operation of the compressor.

[0220] And, when the above-mentioned refrigeration fan module (240) is operated, the air inside the freezer (12) flows through the evaporator (40) by the air blowing force of the above-mentioned refrigeration fan module (240), and heat is exchanged as it passes through the evaporator (40).

[0221] Additionally, the heat-exchanged air (cold air) passes through the first inlet port (211a) of the shroud (210) and flows into the cold air passage (214) for the freezer.

[0222] The cold air that flows into the cold air passage (214) for the freezer and is radiated into the upper space within the cold air passage (214) for the freezer is discharged through the cold air outlet (214e).

[0223] Additionally, the cold air discharged through the above cold air outlet (214e) is guided by the connecting passage (54) and flows into the third cold air passage (131) for the refrigerator room formed in the protrusion (130) of the refrigerator room-side grill fan assembly (1).

[0224] And, the cold air introduced into the third cold air passage (131) flows upward along the third cold air passage (131) and is supplied to the first cold air passage (124) and the second cold air passage (125), respectively. As the cold air continues to flow upward along the first cold air passage (124) and the second cold air passage (125), a portion passes through the first cold air outlet (112a) connected to the first cold air passage (124) and the second cold air outlet (112b) connected to the second cold air passage (125) and is supplied to the middle compartment space within the refrigerator (11), while the remaining portion is supplied to the upper portion of the first cold air passage (124) and the second cold air outlet (112b) connected to the second cold air passage (125). It is provided to the upper compartment space within the refrigerator room (11) through the upper compartment cold air outlet (111) connected to the end.

[0225] In addition, some of the cold air flowing to the upper end of the second cold air passage (125) is directly supplied to the front space within the refrigerator (11) through the upper connecting duct (128) and guide duct (129) connected to the branch passage (125c).

[0226] At this time, the first cold air passage (124) for the first refrigerator is configured to receive less cold air than the second cold air passage (125) for the second refrigerator, and the first cold air outlet (112a) for the first middle compartment connected to the first cold air passage (124) for the first refrigerator is formed with a smaller connecting portion than the second cold air outlet (112b) for the second middle compartment connected to the second cold air passage (125) for the second refrigerator.

[0227] Considering this, the cold air supplied to the refrigerator room (11) through the cold air outlet (112b) for the second middle compartment is greater than the cold air supplied to the refrigerator room (11) through the cold air outlet (112a) for the first middle compartment, thereby reducing the temperature difference between the two sides of the refrigerator room (11) that may be caused by the presence or absence of the ice-making room (21).

[0228] Meanwhile, the cold air flowing through the above-mentioned refrigerator room (11) is supplied to the refrigerator room recovery duct (53) through the cold air recovery port (151) formed in the lower grill pan (150), and the circulation is repeated so that the cold air is recovered to the cold air inlet side of the evaporator (40) located inside the freezer room inner case (10c) by the guidance of the above-mentioned refrigerator room recovery duct (53).

[0229] When the inside of the refrigerator room (11) reaches a set temperature due to the aforementioned operation, the flow path opening / closing module (60) is operated to block the connecting flow path (54) and the cold air flow path (131) for the third refrigerator room from each other, thereby preventing additional cold air supply to the refrigerator room (11).

[0230] Next, the process for controlling the temperature of the freezer (12) will be explained with reference to the attached FIG. 40 and FIG. 41.

[0231] The temperature control of the above-mentioned freezer room (12) is performed by the operation of the freezer fan module (240) and the compressor (not shown). That is, the operation for temperature control of the freezer room (12) is performed by the heat exchange operation of the evaporator (40) caused by the operation of the freezer fan module (240) and the operation of the compressor. At this time, the flow path opening / closing module (60) is operated to block the connection flow path section (54) and the cold air flow path (131) for the third refrigerator room.

[0232] And, when the above-mentioned refrigeration fan module (240) is operated, the air inside the freezer (12) flows through the evaporator (40) by the air blowing force of the above-mentioned refrigeration fan module (240), and heat is exchanged as it passes through the evaporator (40).

[0233] Additionally, the heat-exchanged air (cold air) passes through the first inlet port (211a) of the shroud (210) and flows into the cold air passage (214) for the freezer.

[0234] The cold air flowing into the cold air passage (214) for the freezer and radiating into the upper space within the cold air passage (214) for the freezer is discharged into the upper compartment of the freezer (12) through the cold air discharge port (221) for the upper compartment within the cold air passage (214) for the freezer, and the cold air radiating into the lower side within the cold air passage (214) for the freezer is discharged into the middle compartment and the lower compartment of the freezer (12) respectively through the cold air discharge ports (222) for the middle compartment and the cold air discharge ports (223) for the lower compartment.

[0235] Additionally, the cold air supplied into the two freezer rooms (12) by passing through each cold air discharge port (221, 222, 223) flows within the two freezer rooms (12) and is then guided by the two suction guides (224a, 224b) formed in the grill pan (220) and recovered to the air inlet side of the evaporator (40).

[0236] Meanwhile, while temperature control for the aforementioned freezer (12) is being performed, the ice-making fan module (230) can also be operated.

[0237] That is, considering that the ice-making fan module (230) is set to operate at all times except under special conditions (e.g., when the ice-making room is full of ice), continuous ice-making operation can be performed even while refrigeration operation is being performed.

[0238] If ice-making operation is also performed while refrigeration operation is being performed, a flow of cold air is generated by the operation of the ice-making fan module (230) that sequentially passes through the second inlet port (211b) and the cold air passage (213) for the ice-making room.

[0239] In particular, the cold air generated by the operation of the above-mentioned ice-making fan module (230) is partially supplied to the cold air passage (214) for the freezer room through the upper shared passage (215a), and the remainder is supplied to the ice-making room (21) through the cold air duct (51) for the ice-making room connected to the cold air passage (213) for the ice-making room.

[0240] That is, some of the cold air that is blown in after passing through the second inlet port (211b) and entering the cold air passage (213) for the ice room passes through the upper shared passage (215a) and is supplied to the upper space within the cold air passage (214) for the freezer room, and another part of the cold air passes through the lower shared passage (215b) and is supplied to the lower space within the cold air passage (214) for the freezer room, and the remaining part of the cold air is supplied to the ice room (21) through the cold air duct (51) for the ice room connected to the cold air discharge side of the cold air passage (213) for the ice room.

[0241] Thus, since not only the cold air blown by the operation of the refrigeration fan module (240) but also a portion of the cold air blown by the operation of the ice-making fan module (230) is supplied into the freezer (12), sufficient cold air supply can be achieved. This is as illustrated in the attached FIG. 42.

[0242] In particular, the cold air supplied through the upper shared channel (215a) is provided to the upper compartment of the side space connected to the ice-making room recovery duct (52) among the two side spaces within the freezer room (12), thereby enabling the freezer room (12) to be supplied with sufficient cold air.

[0243] In addition, since the cold air supplied through the lower shared channel (215b) is provided to the lower compartment of the side space connected to the ice-making room recovery duct (52) among the two side spaces within the freezer (12), even if the cold air passing through the ice-making room (21) is recovered through the ice-making room recovery duct (52), a rapid rise in temperature of the space is prevented, and the two side spaces within the freezer (12) can be maintained within the same (or similar) temperature range.

[0244] Additionally, during the above-mentioned refrigeration operation (or ice-making operation) or when each operation is stopped, condensation may occur due to the temperature difference between the cold air passage (213) for the ice-making room and the refrigerator room (11), or between the cold air duct (51) for the ice-making room and the refrigerator room (11).

[0245] However, the above condensate flows down along the cold air duct (51) for the ice room to the second circumferential channel rib (213b) of the cold air channel (213) for the ice room, continues to flow into the cold air channel for the freezer room through the lower shared channel (215b) formed in the second circumferential channel rib (213b), and then drains to the outside of the freezer room side grill fan assembly (2).

[0246] Therefore, the malfunction of the ice-making fan module (230) caused by the condensate not being drained and freezing within the cold air passage (213) for the ice-making room can be prevented.

[0247] Next, the operation (ice-making operation) for temperature control of the ice-making room (21) will be explained with reference to the attached FIGS. 43 to 45.

[0248] The temperature control of the above ice-making room (21) is performed by the operation of the ice-making fan module (230). At this time, the compressor may be operated or stopped depending on the operating conditions of the freezer room (12).

[0249] When the above ice-making fan module (230) is operated, the air present in the freezer (12) passes through the evaporator (40) by the air blowing force of the above ice-making fan module (230), then passes through the second inlet hole (211b) of the shroud (210) and flows into the cold air passage (213) for the ice-making room, and is subsequently discharged to the connecting part with the cold air passage (213) for the ice-making room. This is as illustrated in the attached FIGS. 43 and 44.

[0250] That is, some of the cold air that is blown in after passing through the second inlet port (211b) and entering the cold air passage (213) for the ice room passes through the upper shared passage (215a) and is supplied to the upper space within the cold air passage (214) for the freezer room, and another part of the cold air passes through the lower shared passage (215b) and is supplied to the lower space within the cold air passage (214) for the freezer room, and the remaining part of the cold air is supplied to the ice room (21) through the cold air duct (51) for the ice room connected to the cold air discharge side of the cold air passage (213) for the ice room.

[0251] In particular, among the cold air supplied into the cold air passage (213) for the ice-making room by the blowing force of the ice-making fan module (230) after passing through the second inlet hole (211b), the cold air that is radiated to the upper part of the ice-making fan module (230) and then flows to the cold air discharge side guided by the cold air passage (213) for the ice-making room flows along a sufficient distance from the position radiated around the ice-making fan module (230) to the cold air discharge side of the cold air passage (213) for the ice-making room, thereby reducing flow resistance caused by the cold air inlet area and the discharge area being adjacent to each other, or the phenomenon of cold air flowing back and being discharged through the second inlet hole (211b).

[0252] Along with this, the interior of the freezer (12) maintains a pressure state similar to that of the cold air passage (213) for the ice-making room by the cold air supplied through the upper shared passage (215a) and the lower shared passage (215b). That is, since the pressure of the freezer (12) and the ice-making room (21) is roughly balanced, even if only the ice-making fan module (230) is operated for ice-making operation, the cold air of the freezer (12) can be prevented (or minimized) from passing through the cold air passage (214) for the freezer room and the first inlet port (211a) in reverse and flowing into the second inlet port (211b) and the cold air passage (213) for the ice-making room.

[0253] In particular, in the case of the ice-making fan module (230), cold air is blown with a high blowing pressure (fast rotation speed of the ice-making fan), so it can be smoothly conveyed to the ice-making room (21).

[0254] Then, the cold air flowing through the ice-making room (21) flows into the ice-making room recovery duct (52) and is continuously recovered into the freezer room (12) under the guidance of the ice-making room recovery duct (52).

[0255] Afterwards, the cold air recovered into the above-mentioned freezer (12) is immediately sucked into the first suction guide (224a) positioned opposite it and recovered to the air inlet side of the evaporator (40).

[0256] Accordingly, the temperature inside the ice-making room (21) is controlled by the repetitive circulation of the aforementioned air (cold air).

[0257] Ultimately, the refrigerator of the present invention reduces the amount of unnecessary cold air supplied to the space on the side where the first refrigerator door (20a) is located, which is the side where the ice-making room (21) is located, while relatively increasing the amount of cold air supplied to the opposite side, thereby reducing the temperature difference across the entire refrigerator room (12).

[0258] In addition, the refrigerator of the present invention provides a new type of refrigerator that allows cold air blown from the freezer-side grill fan assembly (2) to be smoothly supplied to the refrigerator-side grill fan assembly (1) and also allows for easy maintenance.

[0259] In addition, the refrigerator of the present invention allows the upper grill pan (110) of the refrigerator compartment grill pan assembly (1) to be used universally regardless of the refrigerator model.

[0260] In addition, the refrigerator of the present invention can have the cold air passage (214) for the freezer and the cold air passage (213) for the ice making room shared by providing shared passages (215a, 215b), and thus, even if the freezer fan module (240) and the ice making fan module (230) operate simultaneously, sufficient cold air can be supplied to the freezer room (12), and the phenomenon of cold air flowing back from the freezer room (12) when the ice making fan module (230) operates alone is prevented.

[0261] In addition, since the refrigerator of the present invention is configured to supply cold air to the cold air passage (121) for the refrigerator room of the grill fan assembly (1) by means of a cold air outlet (214e) formed on the upper wall surface (214a) of the cold air passage (214) for the freezer room and a connecting passage (54) connected thereto, selective cold air supply to the refrigerator room (11), the freezer room (12), and the ice room (21) is possible with a single evaporator (40).
