FIG. 3 is a drawing of a refrigerator according to one embodiment, showing a portion of the inner case, the fan, the wires, and the duct separately. FIG. 4 is an exploded view of FIG. 3. FIG. 5 is a drawing of FIG. 4 from a different angle.

Hereinafter, for convenience of explanation, a refrigerator (1) according to various embodiments will be described focusing on the first inner case (13a), which is a part of the inner cases (13a, 13b) forming the first storage compartment (21), and the duct (100) installed in the first storage compartment (21). This is merely an example, and it is of course also possible to assume a case where the duct (100) described below is installed and operated in the second inner case (13b) forming the second storage compartment (23).

Referring to FIGS. 3 to 5, the refrigerator (1) may include a duct (100) configured to guide airflow generated from a fan (110) to a first storage compartment (21).

The duct (100) may be installed in the first inner case (13a). The duct (100) may be arranged to partition the first storage room (21) and the first cooling space (132). The duct (100) may be arranged to partition the first storage room (21) and the first fan receiving groove (131).

The duct cover (160) may include a second guide housing (162) forming a portion (156a) of the guide passage (156). The second guide housing (162) may be formed to extend vertically on the right side of the cover body (161). Accordingly, the guide passage (156) may also be formed to extend vertically (+-Z direction) on the right side of the cover body (161).

For example, the first fan (110) may be placed and operated in the center of the upper side (+Z side) of the duct cover (160). The second guide housing (162) may include a guide flow inlet (163) formed to be opened toward the first fan (110) by being placed on the upper side (+Z direction) of the right side (+Y side) of one end of the duct cover (160), and a guide flow outlet (165) formed to be opened toward the front (+X direction) by being placed on the lower side (-Z direction) of the right side (+Y side) of the other end of the duct cover (160).

The guide euro (156) can be extended to connect the above-mentioned guide euro inlet (163) and guide euro outlet (165).

The first fan receiving groove (131) in which the first fan (110) is received can be connected to the guide flow inlet (163). Therefore, a portion of the airflow discharged through the first fan (110) can be introduced into the guide flow inlet (163).

In addition, the airflow flowing into the guide flow inlet (163) can pass through the guide flow (156) and be discharged forward through the guide flow outlet (165). As will be described later, the airflow discharged through the guide flow outlet (165) can be introduced into the container inlet hole (274) (described later) formed in the storage container (27) to cool the storage space (272) of the storage container (27).

The duct cover (160) may include a cover inlet hole (166) that is open downward on the lower side of the cover body (161).

When the duct (100) is installed in the first inner case (13a), when the first fan (110) operates, the air in the first storage chamber (21) can be introduced to the rear of the duct cover (160) through the cover inlet hole (166) and pass through the first evaporator (120).

The cooled air passing through the first evaporator (120) is sucked in by the first fan (110) and discharged again to the first storage room (21), thereby cooling the first storage room (21).

The duct (100) may include a damper (170) configured to open and close the guide urea (156). For example, the damper (170) may be located at the front of the cover body (161).

The damper (170) can be installed between the guide flow inlet (163) and the guide flow outlet (165). In other words, the damper (170) can be placed on the guide flow (156).

When the guide passage (156) is opened by the damper (170), a portion of the airflow discharged from the first fan (110) can flow into the guide passage inlet (163) and be discharged through the guide passage (156) to the guide passage outlet (165).

The duct cover (160) may include a power supply unit (180) configured to supply power to the damper (170). The power supply unit (180) may be disposed at the rear of the cover body (161). That is, the damper (170) may be disposed at the front of the cover body (161), and the power supply unit (180) that supplies power to the damper (170) may be disposed at the rear of the cover body (161).

For example, a wire (L) connecting a damper (170) and a power supply unit (180) can be arranged to pass through a slit (167) formed to penetrate the cover body (161) of the duct cover (160) to connect the damper (170) and the power supply unit (180).

The duct plate (140) can be coupled to the duct cover (160) to cover the front of the cover body (161). The duct plate (140) can include a plate body (141) forming an outer shape, a first plate exhaust hole (142) formed in the upper center of the plate body (141) to communicate with the first fan receiving groove (131) and the first storage chamber (21), and a second plate exhaust hole (145) that is open toward the front and communicates with the guide flow path outlet (165) of the duct cover (160).

The second plate exhaust hole (145) can be formed as a space surrounded by a connecting member (144) connected to the container inlet hole (274) of the storage container (27).

For example, the duct plate (140) may have a roughly rectangular shape, but is not limited thereto.

When the duct plate (140) is combined with the duct cover (160), the plate body (141) can partition the first fan receiving groove (131) and the guide path (156) from the first storage chamber (21).

The duct plate (140) may include a plate inlet hole (143) formed at the lower center. The plate inlet hole (143) may communicate with the first storage chamber (21) and the cover inlet hole (166). Accordingly, the first storage chamber (21) may communicate with the first cooling space (132) and the first fan receiving groove (131) through the plate inlet hole (143) and the cover inlet hole (166).

The first plate exhaust hole (142) can be communicated with the first fan receiving groove (131). Therefore, when the first fan (110) operates, the air in the first storage chamber (21) can be introduced into the plate inlet hole (143), pass through the cover inlet hole (166), be cooled in the first evaporator (120), and then be discharged forward by the first fan (110), pass through the first plate exhaust hole (142), and be discharged into the first storage chamber (21).

The second plate exhaust hole (145) can be communicated with the guide flow outlet (165) of the duct cover (160). Therefore, when the first fan (110) operates, air in the first storage chamber (21) can be introduced into the plate inlet hole (143), pass through the cover inlet hole (166), be cooled in the first evaporator (120), and then be introduced into the guide flow outlet (156) by the first fan (110). The air that passes through the guide flow outlet (165) and is discharged forward can be discharged into the storage space (272) of the storage container (27) through the second plate exhaust hole (145).

The duct insulation (150) may include an insulation body (151) that forms an outer shape. For example, the insulation body (151) may include an insulation material.

Since the duct insulation (150) is placed between the duct plate (140) and the duct cover (160), the duct insulation (150) can insulate the first cooling space (132) by dividing it from the first storage room (21). Accordingly, the phenomenon of the temperature of the air cooled while passing through the first evaporator (120) rising due to the temperature of the first storage room (21) can be prevented.

The duct insulation (150) may include a first insulation exhaust hole (152) formed in the upper center of the insulation body (151).

The first insulation exhaust hole (152) can communicate with the first fan receiving groove (131) and the first plate exhaust hole (142). In conclusion, the first fan receiving groove (131) can communicate with the first storage chamber (21) through the first insulation exhaust hole (152) and the first plate exhaust hole (142), so that the air current generated from the first fan (110) can flow into the first storage chamber (21).

The duct insulation (150) may include a first guide housing (153) forming the remaining portion of the guide passage (156).

For example, the first guide housing (153) may be formed at the lower right side of the insulation body (151). In other words, the first guide housing (153) may be formed so as to be positioned corresponding to the position of the second guide housing (162) when the duct insulation (150) comes into contact with the duct cover (160).

A second insulation exhaust hole (155) may be formed at the lower right side of the duct insulation (150). The second insulation exhaust hole (155) may be connected to the aforementioned guide flow outlet (165) and the second plate exhaust hole (145). In addition, the container inlet hole (274) of the storage container (27) may be formed at the rear of the container body (273) to penetrate the container body (273).

In conclusion, the first fan receiving groove (131) can be communicated with the storage space (272) of the storage container (27) through the guide duct (156), the guide duct outlet (165), the second insulation exhaust hole (155), and the second plate exhaust hole (145), so that the air current generated from the first fan (110) can flow into the storage space (272) of the storage container (27).

Fig. 6 is an enlarged view of a portion of a contact portion of a duct in a refrigerator according to one embodiment. Fig. 7 is a view showing Fig. 6 from a different angle. Fig. 8 is a cross-sectional view taken along line a-a' of Fig. 6.

Referring to FIGS. 6 to 8, the duct (100) may include a contact portion (200) that is provided to come into contact with one surface (13a') of the first inner surface (13a) when installed on the first inner surface. The contact portion (200) may be formed on the rear surface of the duct cover (160).

More specifically, the contact portion (200) may have a contact surface that protrudes rearward from the edge of the first cooling space (132) and contacts one surface of the inner case (13a, 13b).

The first cooling space (132) is required to prevent the air passing through the first evaporator (120) from leaking out, as the air is cooled to a temperature lower than the surroundings. Therefore, if the duct cover (160) is provided so that it is in close contact with the inner case (13a, 13b) by the contact surface, the first cooling space (132) can be partitioned from spaces other than the first cooling space (132), thereby minimizing the leak of cold air.

As described above, the damper (170) can be connected to the power supply unit (180) and supplied with power. At this time, the power supply unit (180) can be placed on the opposite side of the damper (170) based on the contact surface, so the wire (L) connecting the power supply unit (180) and the damper (170) can be arranged to pass through the contact unit (200).

In the city, the wire (L) is expressed as passing through the contact portion (200) in the left-right direction (+-Y direction), but this is merely an example. For example, the wire (L) may extend in various directions, including forward (+X direction), backward (-X direction), left-right (+-Y direction), and up-down (+-Z direction), in order to connect a plurality of components that must be electrically connected to each other, and may be arranged to be bent, folded, or twisted to transmit electrical signals and power, etc.

Below, a structure that allows a wire (L) to pass through a contact portion (200) is examined.

The contact portion (200) may include a passage (230) formed to be sunken into the contact surface so that a wire (L) may be placed therein, and a protrusion (240, 250) protruding from the inside of the passage so that the wire (L) passing through the passage (230) is caught to prevent the wire (L) from being separated from the passage (230), thereby supporting the wire (L).

The passage (230) can be formed by recessing from the rearward-facing contact surface (211, 221) toward the front (+X direction). The passage (230) can be formed in a part of the contact surface (211, 221).

For example, the passage (230) may be formed to extend in the left-right direction (+-Y direction). For example, the diameter of the passage (230) may be greater than or equal to the diameter (l) of the wire (L).

For example, the contact surfaces (211, 221) may be provided to extend in the vertical direction (+-Z direction), and the passage (230) may be formed by being recessed in the contact surfaces (211, 221) to extend in the left-right direction (+-Y direction). Accordingly, the contact surfaces (211, 221) may be separated into an upper contact surface (211) and a lower contact surface (221) by the passage (230).

The upper contact surface (221) may be referred to as a first contact surface (211), and the lower contact surface (221) may be referred to as a second contact surface (221). In addition, a part of the contact portion (200) where the first contact surface (211) is located may be referred to as a first contact area (210), and another part of the contact portion (200) where the second contact surface (221) is located may be referred to as a second contact area (220).

The protrusions (240, 250) protrude from the inner surface (210a, 220a) and can pressurize the wire (L) passing through the passage (230).

For convenience of explanation, in the following description, two protrusions (240, 250) are illustrated and described.

For example, the protrusions (240, 250) may include a first protrusion (250) protruding in a first direction from an inner surface (210a) of the passage (230), and a second protrusion (240) protruding in a second direction different from the first direction from an inner surface (220a) of the passage (230).

The inner side (210a) of the passage (230) may be referred to as the first inner side (210a), and the inner side (220a) of the passage (230) may be referred to as the second inner side (220a).

For example, the first direction may be downward (-Z direction) and the second direction may be upward (+Z direction).

As previously discussed, the case where two protrusions are formed and the protrusions protrude in downward and upward directions, respectively, is only one of several embodiments. For example, a case where three protrusions are formed and protrude sequentially upward, downward, and upward may also be considered. A case where adjacent protrusions protrude in the same direction to catch the wire (L) and a case where three or more protrusions protrude from one side of the passage (230) may also be considered.

In addition, even in the case of the direction in which the protrusion protrudes, it can include both the forward/backward direction (+-X direction) and the left/right direction (+-Y direction) other than the above-mentioned downward (-Z direction) or upward (+Z direction), and it goes without saying that it can protrude in various directions other than the above-mentioned directions as needed.

The first protrusion (250) and the second protrusion (240) can be formed to press the first portion (L1) and the second portion (L2) of the wire (L), respectively (see FIG. 9). Accordingly, the wire (L) passing through the passage (230) can be more stably settled within the passage (230), and the phenomenon of the wire (L) being separated from the passage (230) can be prevented.

The length (d4, d5) at which the first protrusion (250) and the second protrusion (240) protrude may be a length at which each protruding end (251a) does not come into contact with the inner surface (220a) of the passage (230).

The passage (230) may include a first passage (231) formed by the end (250a) of the first projection and the second inner side (220a) being spaced apart from each other. For example, the passage (230) may include a first through hole (261) that is opened toward the damper (170) so that a wire (L) extending from the damper (170) may be inserted into the first passage (231). For example, the first through hole (261) may be formed to be open to the side of the contact portion (200).

In the city (see Fig. 9), the shape of the end (250a) of the first protrusion is depicted as having a shape roughly like a plane, but this is merely an example, and the end (250a) of the first protrusion can be formed in various ways, such as including a shape roughly like a vertex. This can also be applied to the end (240a) of the second protrusion, which will be described later.

For example, a wire (L) connected to the damper (170) and extending from the damper (170) can be inserted into the first passage (231) through the first through hole (261).

The passage (230) may include a second passage (232) formed by the end (240a) of the second projection and the first inner side (210a) being spaced apart from each other, and a communication portion (233) that is arranged between the first passage (231) and the second passage (232) and connects the first passage (231) and the second passage (232).

For example, a wire (L) inserted into the first passage (231) can pass through the connecting portion (233) and be inserted into the second passage (232).

For example, the communication portion (233) may be a space formed by a side surface (250b) of the first protrusion and a side surface (240b) of the second protrusion facing the side surface (250b) of the first protrusion.

The second passage (232) may include a second through hole (262) formed on the side of the contact portion (200) and open toward the power supply portion (180). A wire (L) inserted into the second passage (232) may pass through the second through hole (262) and be connected to the power supply portion (180). Accordingly, the wire (L) may pass through the contact portion (200) and connect the damper (170) and the power supply portion (180).

For example, the power supply unit (180) may include a power terminal (183) electrically connected to a wire (L) extending from components requiring power supply, a power case (181) accommodating the power terminal (183), and a power communication hole (182) formed on one side of the power case (181) to connect the wire (L) to the power terminal (183). For example, a wire (L) extending from a damper (170) and passing through a contact portion (200) may be connected to the power terminal (183) to supply power to the damper (170).

For example, the passage (230) may include an opening (234) that is open toward the rear (-Z direction). The opening (234) may be a portion of the passage (230) that is formed on the same line as the contact surface. The opening (234) may be formed between the first contact area (210) and the second contact area (220). The opening (234) may be formed between the first contact surface (211) and the second contact surface (221) to space the first contact surface (211) and the second contact surface (221).

For example, a wire (L) can be inserted into a passage (230) through an opening (234). The wire (L) inserted into the opening (234) can be arranged so that one side passes through the first through hole (261), the other side passes through the second through hole (262), and the portion between the one side and the other side of the wire (L) is positioned on the passage (230). Therefore, a user can more easily insert the wire (L) into the passage (230).

For example, the contact portion (200) may include a lead portion (251) extending downward (-Z direction) from the first protrusion (250) to cover a portion of the opening (234). The lead portion (251) may be positioned so as to be in the same line as the rear surface of the first protrusion (250).

For example, the thickness of the lead portion (251) in the front-back direction may be formed thinner than the thickness of the first protrusion (250) in the front-back direction. A part of the opening (234) covered by the lead portion (251) may be a part that communicates with the first passage (231). Therefore, the phenomenon of the wire (L) arranged in the passage (230) being separated from the opening (234) by the lead portion (251) can be prevented.

The lead portion (251) may be extended so that one end (251a) of the lead portion does not come into contact with the inner surface of the passage (230). In other words, the length (d6-d4-d1) by which the lead portion (251) extends may be shorter than the distance (d2) between the end (250a) of the first protrusion and the second inner surface (220a). That is, the lead portion (251) may be formed so that one end (251a) of the lead portion is spaced apart from the second inner surface (220a).

The distance (d1) between one end (251a) of the lead portion and the second inner side (220a) may be greater than the diameter (l) of the wire (L). Therefore, the wire (L) may be inserted into the passage (230) even through a part of the opening (234) that is not covered by the lead portion (251). For example, the one end (251a) of the lead portion may be the one end (251a) of the lead portion facing downward.

In the above, for the convenience of explanation, it has been described that the lead portion (251) extends from the first protrusion (250), but it is also possible to assume that the lead portion (251) extends from the second protrusion (240) and covers a portion of the opening (234) connected to the second passage (232).

The refrigerator (1) may include a sealing member (190) disposed between the inner case (13a, 13b) and the contact surface (211, 221). For example, the sealing member (190) may include an elastic material.

When the duct (100) is installed on the first inner surface (13a), the sealing member (190) is placed between the first inner surface (13a) and the contact surface (211, 221) to improve the contact between the duct (100) and the first inner surface (13a). Accordingly, the phenomenon of cold air in the first cooling space (132) leaking out through the contact surface can be prevented.

For example, the sealing member (190) may include an insulating material. Accordingly, the phenomenon of the first cooling space (132) being heated by heat conducted from a space other than the first cooling space (132) can be prevented.

For example, the sealing member (190) can be attached to the contact surface to cover the opening (234). Since the sealing member (190) is arranged to cover the opening (234), the phenomenon of the wire (L) arranged in the passage (230) being separated from the passage (230) through the opening (234) can be prevented. The sealing member (190) can connect the first contact surface (211) and the second contact surface (221). The sealing member (190) can connect the first contact area (210) and the second contact area (220).

Fig. 9 is a cross-sectional view taken along the b-b' line of Fig. 6. Fig. 10 is a cross-sectional view taken along the c-c' line of Fig. 6.

Referring to FIGS. 9 and 10, the passage (230) may be formed to be sunken toward the front (+X direction) from the contact surface (211, 221). Accordingly, the communication portion (233) connecting the first passage (231) and the second passage (232) may be formed in a direction extending from the rear toward the front.

The diameter (d7) of one end of the communicating portion (233) adjacent to the contact surface may be formed to be larger than the diameter (l) of the wire (L). In other words, the diameter (d7) of one end of the communicating portion (233) forming a part of the opening (234) may be formed to be larger than the diameter (l) of the wire (L). In other words, the diameter (d7) of the rear end of the communicating portion (233) may be formed to be larger than the diameter (l) of the wire (L). Accordingly, the wire (L) inserted through the opening (234) can smoothly pass through the rear of the communicating portion (233) and be placed in the communicating portion (233).

The diameter (d8) of the other end of the communication portion (233) can be formed to correspond to the diameter (l) of the wire (L). In other words, the diameter (d8) of the front end of the communication portion (233) can be formed to correspond to the diameter (l) of the wire (L). Accordingly, when the wire (L) arranged in the communication portion (233) moves to the front (+X direction) end of the communication portion (233), it can be arranged in the communication portion (233) more stably.

For example, the diameter (d8) of the other end of the communication portion (233) may be formed to be smaller than the diameter (l) of the wire (L). In other words, the diameter (d8) of the front end of the communication portion (233) may be formed to be smaller than the diameter (l) of the wire (L). Accordingly, when the wire (L) arranged in the communication portion (233) moves to the front end of the communication portion (233), it can be arranged in the communication portion (233) more stably.

In conclusion, the diameter of the connecting portion (233) may have a cross-section that becomes smaller as it moves forward from the contact surface. Accordingly, it becomes possible to more stably accommodate wires (L) having various diameters.

For example, the sum of the protruding length (d4) of the first protrusion (250) and the protruding length (d5) of the second protrusion (240) may be longer than the diameter (d6) of the passage (230). In other words, the first protrusion (250) and the second protrusion (240) may protrude so that their respective ends do not contact each other. In other words, the first protrusion (250) and the second protrusion (240) may protrude at positions that are opposite to each other. In other words, the position in the left-right direction (+-Y direction) at which the first protrusion (250) protrudes may be different from the position in the left-right direction (+-Y direction) at which the second protrusion (240) protrudes.

For example, the position of the end (250a) of the first protrusion (250) in the vertical direction (+-Z direction) may be located lower than the position of the end (240a) of the second protrusion (240) in the vertical direction (+-Z direction). Accordingly, when the wire extends through the first passage (231) and the communication portion (233) to the second passage (232), the wire (L) may be bent to pass through the end (250a) of the first protrusion (250) and the end (240a) of the second protrusion (240), which have different heights, and may contact the end (250a) of the first protrusion (250) and the end (240a) of the second protrusion (240), respectively.

As described above, since the diameter (l) of the wire (L) is made larger than the diameter (d8) of the other end of the communication portion (233), the wire (L) can be inserted and fixed into the other end of the communication portion (233) and settled inside the passage (230). In addition, as described above, if the wire (L) contacts the end (250a) of the first protrusion (250) and the end (240a) of the second protrusion (240), respectively, the wire (L) can be settled more stably inside the passage (230) due to the frictional force generated by the contact between the wire (L) and the protrusions (240, 250).

Accordingly, the position in the vertical direction (+-Z direction) of the first passage (231) formed by the first protrusion (250) and the position in the vertical direction (+-Z direction) of the second passage (232) formed by the second protrusion (240) may be different from each other. In conclusion, the wire (L) passing through the passage (230) may be arranged to be curved while passing through the first passage (231) and the second passage (232).

The wire (L) placed in the passage (230) can be bent by having the first portion (L1) pressed by the first protrusion (250) and the second portion (L2) pressed by the second protrusion (240). As described above, the first portion (L1) and the second portion (L2) can be parts of different wires (L). Therefore, the wire (L) can be stably placed in the passage (230) by being pressed and supported by the first protrusion (250) and the second protrusion (240).

A refrigerator (1) according to one embodiment includes an inner case (13a, 13b) forming a storage compartment (20), an evaporator (120) configured to generate cold air, and a duct (100) provided at the rear of the storage compartment (20) to supply cold air generated through the evaporator (120) to the storage compartment (20). The duct (100) includes a cooling space formed to be recessed at the rear of the duct (100) so that the evaporator (120) is placed, and a contact portion (200) having a contact surface (211, 221) that protrudes rearward from a rim of the cooling space and contacts one surface of the inner case (13a, 13b). The above contact portion (200) includes a passage (230) formed to be sunken into the contact surface so that a wire can be placed, a first inner surface (210a) forming the passage (230), a second inner surface (220a) forming the passage (230) and facing the first inner surface, a first protrusion (250) protruding in a first direction from the first inner surface (210a) toward the second inner surface (220a), and a second protrusion (240) protruding in a second direction from the second inner surface (220a) toward the first inner surface (210a), wherein an end (240a) of the second protrusion includes the second protrusion (240) closer to the first inner surface (210a) than the end (250a) of the first protrusion.

The first protrusion (250) and the second protrusion (240) may be spaced apart from each other.

The passage (230) may include a first passage (231) formed by separating the end (250a) of the first protrusion and the second inner surface (220a), a second passage (232) formed by separating the end (240a) of the second protrusion and the first inner surface (210a), and a communication portion (233) formed by separating the side surface (250b) of the first protrusion (250) and the side surface (240b) of the second protrusion (240), and connecting the first passage (231) and the second passage (232).

The above passage (230) is formed to be sunken toward the front from the contact surface, and the diameter of the communication portion (233) may become smaller toward the front from the contact surface.

The diameter of one end of the communication portion (233) adjacent to the contact surface may be formed to be larger than the diameter (l) of the wire (L), and the diameter of the other end of the communication portion (233) may be formed to be smaller than the diameter (l) of the wire (L).

The sum (d4+d5) of the protruding length (d4) of the first protrusion (250) and the protruding length (d5) of the second protrusion (240) may be set to be longer than the diameter (d6) of the passage (230).

The passage (230) includes an opening (234) that is open toward the rear so that the wire (L) can be inserted, and the contact portion (200) may further include a lead portion (251) extending downward from the first protrusion (250) to cover a portion of the opening (234).

One end (251a) of the lead portion facing downward can be extended so as to be spaced apart from the inner surface of the passage (230).
