[0110] The sterilizing and deodorizing device (100) mounted on the upper wall of the refrigerator (22) can be connected to a cold air duct (60). The cold air duct (60) can be arranged at the rear of the refrigerator (22). Cold air generated in the evaporator (E) can be induced to move along the cold air duct (60) by a fan (F). The cold air moved along the cold air duct (60) by the fan (F) can be discharged from the cold air duct (60) through a cold air discharge port (61). The cold air discharged from the cold air discharge port (61) can be introduced into the sterilizing and deodorizing device (100). The cold air discharge port (61) can be connected to the inlet port (111) of the sterilizing and deodorizing device (100). Accordingly, the cold air discharged through the cold air discharge port (61) can be introduced into the sterilizing and deodorizing device (100) through the inlet port (111). Hereinafter, the cold air discharged from the cold air discharge port (61) and introduced into the inlet port (111) will be described as air.

[0111] The air introduced into the sterilizing and deodorizing device (100) through the inlet (111) can be sterilized by the sterilizing lamp (140) mounted inside the sterilizing and deodorizing device (100). The air introduced into the sterilizing and deodorizing device (100) through the inlet (111) can be deodorized by the deodorizing filter (150) mounted inside the sterilizing and deodorizing device (100). The air introduced into the sterilizing and deodorizing device (100) and sterilized and deodorized can be discharged into the refrigerator (22) through the outlet (170). The detailed configuration of the sterilizing and deodorizing device (100) will be described below.

[0112] Fig. 6 is a drawing illustrating a sterilizing and deodorizing device according to one embodiment. Fig. 7 is a drawing illustrating an exploded view of a sterilizing and deodorizing device according to one embodiment. Fig. 8 is a plan view illustrating a sterilizing lamp, a deodorizing filter, and a deodorizing lamp mounted inside a second housing according to one embodiment, and an insulating tape attached thereto. Fig. 9 is a cross-sectional view illustrating a blocking rib provided adjacent to an inlet of a sterilizing and deodorizing device according to one embodiment.

[0113] Hereinafter, when describing the sterilizing and deodorizing device (100), the part where the discharge port (170) is located may be considered as the front, and the part where the inlet port (111) is located may be considered as the rear, based on the inlet (111) and the discharge port (170). In addition, although the sterilizing and deodorizing device (100) is described as being mounted on the upper wall of the refrigerator compartment (22), it is not limited thereto. That is, it may be mounted on a part other than the upper wall of the refrigerator compartment (22). In addition, the sterilizing and deodorizing device (100) may be mounted inside the freezer compartment (23, 24) rather than the refrigerator compartment (22). In addition, the sterilizing and deodorizing device (100) may be mounted inside both the refrigerator compartment (22) and the freezer compartment (23, 24). (See FIG. 2)

[0114] As illustrated in FIGS. 6 to 9, the sterilizing and deodorizing device (100) may include a housing (110). The housing (110) may be mounted on the upper wall of the refrigerator compartment (22). The housing (110) may include a first housing (120) mounted on the upper wall of the refrigerator compartment (22). The housing (110) may include a second housing (130) mounted on the lower portion of the first housing (120). The housing (110) may include an inlet (111) through which air is introduced. The inlet (111) may be formed by the first housing (120) and the second housing (130). The inlet (111) may be connected to a duct outlet (61) of a cold air duct (60). Air discharged from the duct outlet (61) of the cold air duct (60) can be introduced into the inlet (111). The air introduced into the housing (110) through the inlet (111) can be sterilized and deodorized by the sterilizing lamp (140) and deodorizing filter (150) mounted inside the housing (110). The sterilized and deodorized air can be discharged into the refrigerator compartment (22) through the outlet (170). (See FIGS. 2 and 3)

[0115] The housing (110) may include a blocking rib (113) that prevents ultraviolet rays emitted from the germicidal lamp (140) from leaking out of the housing (110) through the inlet (111). Air drawn into the housing (110) may be sterilized by ultraviolet rays emitted from the germicidal lamp (140) mounted inside the housing (110). Ultraviolet rays emitted from the germicidal lamp (140) may be prevented from leaking into the cold air duct (60) through the inlet (111) by the blocking rib (113).

[0116] A blocking rib (113) may be provided in each of the first housing (120) and the second housing (130) adjacent to the inlet (111). The blocking rib (113) may include a first blocking rib (114) formed in the first housing (120). The first blocking rib (114) may be formed to extend downward from the upper wall of the first housing (120).

[0117] The blocking rib (113) may include a second blocking rib (115) formed in the second housing (130). The second blocking rib (115) may be formed to extend upward from the lower wall of the second housing (130).

[0118] The first blocking rib (114) and the second blocking rib (115) may be formed at the same position based on the flow direction of air flowing into the inlet (111). Therefore, a space may be formed between the first blocking rib (114) and the second blocking rib (115) so that the air flowing into the inlet (111) may flow into the interior of the housing (110). That is, the first blocking rib (114) and the second blocking rib (115) may be spaced apart from each other.

[0119] Although a portion of the ultraviolet rays emitted from the sterilizing lamp (140) can be prevented from leaking into the inlet (111) by the blocking rib (113), a portion of the ultraviolet rays can leak into the inlet (111) because a space is formed between the first blocking rib (114) and the second blocking rib (115). The ultraviolet rays leaking into the inlet (111) through the space between the first blocking rib (114) and the second blocking rib (115) can enter the cold air duct (60) through the duct outlet (61). A portion of the cold air duct (60) adjacent to the duct outlet (61) can be sterilized by the ultraviolet rays entering the cold air duct (60) through the duct outlet (61).

[0120] The second housing (130) may include a germicidal lamp mounting portion (131) in which a germicidal lamp (140) is mounted. The germicidal lamp mounting portion (131) may be provided on the lower wall of the second housing (130). The germicidal lamp mounting portion (131) may be provided on the central portion of the lower wall of the second housing (130). The central portion of the lower wall of the second housing (130) may be a position based on the direction of flow of air introduced into the interior of the housing (110). Both ends of a germicidal lamp (140) having a cylindrical shape may be mounted on the germicidal lamp mounting portion (131).

[0121] The second housing (130) may include a deodorizing filter mounting portion (132) on which a deodorizing filter (150) is mounted. The deodorizing filter mounting portion (132) may be provided on the lower wall of the second housing (130). The deodorizing filter mounting portion (132) may be provided in front of the sterilizing lamp mounting portion (131).

[0122] The second housing (130) may include a deodorizing lamp mounting portion (133) in which a deodorizing lamp (160) is mounted. The deodorizing lamp mounting portion (133) may be provided on the lower wall of the second housing (130). The deodorizing lamp mounting portion (133) may be provided in front of the deodorizing filter mounting portion (132). That is, the deodorizing lamp mounting portion (133) may be provided on the opposite side of the sterilizing lamp mounting portion (131) with the deodorizing filter mounting portion (132) as the center.

[0123] Accordingly, the inlet (111), sterilizing filter mounting portion (131), deodorizing filter mounting portion (132), and deodorizing lamp mounting portion (133) provided in the housing (110) can be arranged sequentially along the flow direction of air introduced into the interior of the housing (110). In other words, the inlet (111), sterilizing filter (140), deodorizing filter (150), and deodorizing lamp (160) can be arranged sequentially along the flow direction of air introduced into the interior of the housing (110).

[0124] The second housing (130) may include deodorizing filter ribs (134) provided on the left and right sides of the deodorizing filter (150). That is, the deodorizing filter ribs (134) may be provided on the left and right sides of the deodorizing filter mounting portion (132). The deodorizing filter ribs (134) may prevent ultraviolet rays emitted from the sterilizing lamp (140) from leaking out through the outlet (170). That is, the deodorizing filter ribs (134) may prevent ultraviolet rays emitted from the sterilizing lamp (140) from leaking into the refrigerator compartment (22, see FIG. 2) through the outlet (170).

[0125] The deodorizing filter rib (134) may include a first deodorizing filter rib (135) provided on the left side of the deodorizing filter (150). That is, the first deodorizing filter rib (135) may be provided on the left side of the deodorizing filter mounting portion (132). At this time, the left side of the deodorizing filter (150) may be taken as a reference when looking at the housing (110) from the front of the housing (110).

[0126] The deodorizing filter rib (134) may include a second deodorizing filter rib (136) provided on the right side of the deodorizing filter (150). That is, the second deodorizing filter rib (136) may be provided on the right side of the deodorizing filter mounting portion (132).

[0127] The length (D1) between the left end of the first deodorizing filter rib (135) and the right end of the second deodorizing filter rib (136) may be set longer than the length (D2) of the sterilizing lamp (140). Since the length (D1) between the left end of the first deodorizing filter rib (135) and the right end of the second deodorizing filter rib (136) is set longer than the length (D2) of the sterilizing lamp (140), it is possible to prevent ultraviolet rays emitted from the sterilizing lamp (140) from leaking into the refrigerator compartment (22, see FIG. 2) through the outlet (170).

[0128] The second housing (130) may include a deodorizing lamp rib (137) provided in front of the deodorizing lamp (160). That is, the deodorizing lamp rib (137) may be provided in front of the deodorizing lamp mounting portion (133). The deodorizing lamp rib (137) may prevent ultraviolet rays emitted from the germicidal lamp (140) from leaking out through the discharge port (170). That is, the deodorizing lamp rib (137) may prevent ultraviolet rays emitted from the germicidal lamp (140) from leaking into the refrigerator compartment (22, see FIG. 2) through the discharge port (170). In addition, the deodorizing lamp rib (137) may prevent ultraviolet rays emitted from the deodorizing lamp (160) from leaking into the refrigerator compartment (22, see FIG. 2) through the discharge port (170). The length (D3) of the deodorizing lamp rib (137) can be made longer than the length (D4) of the deodorizing filter (150).

[0129] The deodorizing filter rib (134) and the deodorizing lamp rib (137) can guide the air that has been introduced into the housing (110) and sterilized and deodorized to be smoothly discharged through the discharge port (170). That is, the air that has been introduced into the housing (110) and sterilized and deodorized can be guided through the space between the deodorizing filter rib (134) and the deodorizing lamp rib (137) to be smoothly discharged through the discharge port (170).

[0130] The sterilizing and deodorizing device (100) may include a sterilizing lamp (140). The sterilizing lamp (140) may be a UVC (Ultraviolet C) lamp that emits ultraviolet rays. The sterilizing lamp (140) may be provided to have a cylindrical shape. Since the sterilizing lamp (140) is provided to have a cylindrical shape, ultraviolet rays emitted from the sterilizing lamp (140) may be emitted in a 360-degree direction. The sterilizing lamp (140) may be mounted on a sterilizing lamp mounting portion (131) provided on a second housing (130). Both ends of the sterilizing lamp (140) may be mounted on the sterilizing lamp mounting portion (131). The sterilizing lamp (140) may sterilize air introduced through the inlet (111) by emitting ultraviolet rays. Air sterilized by ultraviolet rays emitted from a sterilizing lamp (140) can be discharged into the refrigerator (22, see FIG. 2) through the discharge port (170).

[0131] The sterilizing lamp (140) may be provided between the inlet (111) and the deodorizing filter (150). Since the sterilizing lamp (140) is provided between the inlet (111) and the deodorizing filter (150), a sterilizing area (S) in which air introduced into the inlet (111) is sterilized by ultraviolet rays emitted from the sterilizing lamp (140) may be formed in the section between the inlet (111) and the deodorizing filter (150). That is, the air introduced into the inlet (111) may be sterilized while flowing through the sterilizing area (S) formed in the section between the inlet (111) and the deodorizing filter (150), and then may be discharged through the discharge port (170). As described above, since the sterilizing lamp (140) capable of 360-degree ultraviolet ray emission is arranged in the central portion of the interior of the housing (110), the sterilizing area (S) for sterilizing air may be secured to the greatest extent possible. In addition, since a sterilizing lamp (140) capable of 360-degree ultraviolet radiation is placed in the central part of the housing (110), the sterilizing time for sterilizing the air can be secured to the maximum extent.

[0132] The sterilization zone (S) may include a first sterilization zone (S1) formed in the section between the inlet (111) and the sterilization lamp (140). The sterilization zone (S) may include a second sterilization zone (S2) formed in the section between the sterilization lamp (140) and the deodorizing filter (150).

[0133] The distance (L1) between the inlet (111) and the sterilizing lamp (140), which is the first sterilizing area (S1), can be set longer than the distance (L2) between the sterilizing lamp (140) and the deodorizing filter (150), which is the second sterilizing area (S2). If the distance (L1) between the inlet (111) and the sterilizing lamp (140), which is the first sterilizing area (S1), is set longer than the distance (L2) between the sterilizing lamp (140) and the deodorizing filter (150), which is the second sterilizing area (S2), the sterilizing area (S) can be maximized while ensuring that the sterilizing lamp (140) and the deodorizing filter (150) are positioned within a certain distance. When the sterilizing lamp (140) and the deodorizing filter (150) are positioned within a certain distance, the deodorizing filter (150) can be activated by ultraviolet rays emitted from the sterilizing lamp (140). When the deodorizing filter (150) is activated by ultraviolet rays emitted from the sterilizing lamp (140), air drawn into the inlet (111) can be deodorized by the deodorizing filter (150) and then discharged into the refrigerator compartment (22, see FIG. 2) through the discharge port (170). As described above, since sterilization and / or deodorization of air is possible through a single lamp, the sterilizing lamp (140), the efficiency of power consumption can be increased. In addition, the overall volume of the sterilizing and deodorizing device (100) can be minimized.

[0134] The sterilizing and deodorizing device (100) may include a deodorizing filter (150). The deodorizing filter (150) may be mounted on a deodorizing filter mounting portion (132) provided in the second housing (130). The deodorizing filter (150) may be positioned in front of the sterilizing lamp (140). That is, the deodorizing filter (150) may be positioned so that the sterilizing lamp (140) is positioned between the inlet (111) and the deodorizing filter (150). The deodorizing filter (150) may be activated by ultraviolet rays emitted from the sterilizing lamp (140). The deodorizing filter (150) activated by ultraviolet rays emitted from the sterilizing lamp (140) may deodorize air introduced through the inlet (111). The air deodorized by the deodorizing filter (150) can be discharged into the refrigerator (22, see FIG. 2) through the discharge port (170).

[0135] The sterilizing and deodorizing device (100) may include a deodorizing lamp (160). The deodorizing lamp (160) may be mounted on a deodorizing lamp mounting portion (133) provided in the second housing (130). The deodorizing lamp (160) may be positioned in front of the deodorizing filter (150). That is, the deodorizing lamp (160) may be positioned on the opposite side of the sterilizing lamp (140) with the deodorizing filter (150) as the center. Accordingly, the inlet (111), the sterilizing lamp (140), the deodorizing filter (150), and the deodorizing lamp (160) may be sequentially positioned along the direction of air flow that is discharged from the duct outlet (61) of the cold air duct (60) and introduced into the sterilizing and deodorizing device (100).

[0136] The deodorizing lamp (160) can selectively activate the deodorizing filter (150). When the contamination level of the air inside the refrigerator (22) or the opening and closing of the refrigerator door (31) is detected and it is necessary to sterilize and deodorize the air inside the refrigerator (22), the sterilizing lamp (140) can be turned on for sterilization and deodorization operation. When the sterilizing lamp (140) is turned on and ultraviolet rays are emitted from the sterilizing lamp (140), the air introduced into the inlet (111) can be sterilized. In addition, the deodorizing filter (150) is activated by the ultraviolet rays emitted from the sterilizing lamp (140), and the air introduced into the inlet (111) can be deodorized. The air sterilized and deodorized by the sterilizing lamp (140) and the deodorizing filter (150) can be discharged through the discharge port (170). (See FIGS. 1 and 2)

[0137] When the required sterilization time is determined to have elapsed by judging the level of contamination inside the refrigerator (22) and the accumulated operation time of the sterilization / deodorization operation, the sterilization lamp (140) can be turned OFF and the deodorization lamp (160) can be turned ON. That is, by turning OFF the sterilization lamp (140) to stop sterilizing the air and turning ON the deodorization lamp (160) to activate the deodorization filter (150), the deodorization of the air by the deodorization filter (150) can be maintained continuously.

[0138] When the contamination level inside the refrigerator (22) and the accumulated operation time of the sterilization / deodorization operation are judged to be sufficient to determine that the deodorization time has elapsed, the deodorization lamp (160) can be turned off.

[0139] The sterilizing and deodorizing device (100) may include a discharge port (170). The discharge port (170) may discharge air that has been introduced into the inlet port (111) and sterilized and deodorized by the sterilizing lamp (140) and / or the deodorizing filter (150) into the refrigerator compartment (22, see FIG. 2). The discharge port (170) may be provided in the second housing (130). The discharge port (170) may be provided between the deodorizing filter (150) and the deodorizing lamp (160). Accordingly, the inlet (111), the sterilizing lamp (140), the deodorizing filter (150), the outlet (170), and the deodorizing lamp (160) can be arranged sequentially along the direction of flow of air discharged from the duct outlet (61) of the cold air duct (60) and introduced into the sterilizing and deodorizing device (100). As described above, since the inlet (111), the sterilizing lamp (140), the deodorizing filter (150), the outlet (170), and the deodorizing lamp (160) implement a straight flow path, the loss of air flow can be minimized while sterilizing and / or deodorizing the air.

[0140] The outlet (170) may include a first outlet (171) formed in a hole shape between the deodorizing filter (150) and the deodorizing lamp (160). The first outlet (171) may be formed on the lower wall of the second housing (130). Air that is introduced into the inlet (111) and sterilized and deodorized by the sterilizing lamp (140) and / or the deodorizing filter (150) may be discharged into the refrigerator compartment (22, see FIG. 2) through the first outlet (171).

[0141] The outlet (170) may include a second outlet (173) formed on the left and right sides of the first outlet (171) by a deodorizing filter rib (134) and a deodorizing lamp rib (137). Air that flows into the inlet (111) and is sterilized and deodorized by the sterilizing lamp (140) and / or the deodorizing filter (150) may be guided by the deodorizing filter rib (134) and the deodorizing lamp rib (137) and discharged into the refrigerator compartment (22, see FIG. 2) through the second outlet (173).

[0142] The sterilizing and deodorizing device (100) may include an insulating tape (180) attached to a wall surface of a housing (110). The insulating tape (180) may be attached to a wall surface of the housing (110) adjacent to a refrigerator compartment (22, see FIG. 2). The insulating tape (180) may be attached to a lower wall inside a second housing (130) adjacent to the refrigerator compartment (22, see FIG. 2). The insulating tape (180) may dissipate heat generated from a sterilizing lamp (140).

[0143] The insulation tape (180) may include a reflective layer (181) that reflects ultraviolet rays emitted from the germicidal lamp (140). The reflective layer (181) may be formed of a metal material. The reflective layer (181) reflects ultraviolet rays emitted from the germicidal lamp (140) and prevents the ultraviolet rays emitted from the germicidal lamp (140) from directly reaching the surface of the housing (110). In particular, when the housing (110) is formed as an injection-molded product, the ultraviolet rays emitted from the germicidal lamp (140) are prevented from directly reaching the surface of the housing (110) by the reflective layer (181), so that photodegradation of the housing (110) can be prevented. In addition, since the ultraviolet rays emitted from the germicidal lamp (140) are reflected by the reflective layer (181), a re-sterilization effect of the air can be generated.

[0144] The insulating tape (180) may include an insulating layer (183) that prevents heat generated from the sterilizing lamp (140) from moving to the refrigerator (22). The insulating layer (183) may prevent heat generated when the sterilizing lamp (140) emits ultraviolet rays from moving to the refrigerator (22) and causing the temperature inside the refrigerator (22) to rise.

[0145] As described above, by attaching the insulation tape (180) to the lower wall inside the second housing (130) adjacent to the refrigerator compartment (22, see FIG. 2), it is possible to prevent dew from forming on the surface of the second housing (130) adjacent to the refrigerator compartment (22, see FIG. 2). In addition, by attaching the insulation tape (180) to the lower wall inside the second housing (130) adjacent to the refrigerator compartment (22, see FIG. 2), it is possible to prevent loss of output of the sterilizing lamp (140). In addition, by attaching the insulation tape (180) to the lower wall inside the second housing (130) adjacent to the refrigerator compartment (22, see FIG. 2), it is possible to extend the life of the sterilizing lamp (140).

[0146] The insulating tape (180) can be arranged so that the reflective layer (181) is positioned on top of the insulating layer (183).

[0147] Fig. 10 is a cross-sectional view illustrating a first blocking rib provided adjacent to an inlet of a sterilizing and deodorizing device according to one embodiment, wherein the first blocking rib is formed in front of a second blocking rib. Fig. 11 is a cross-sectional view illustrating a second blocking rib provided adjacent to an inlet of a sterilizing and deodorizing device according to one embodiment, wherein the second blocking rib is formed in front of a first blocking rib.

[0148] As illustrated in FIG. 10, the housing (110) may include a blocking rib (113) that prevents ultraviolet rays emitted from the germicidal lamp (140) from leaking out of the housing (110) through the inlet (111). Air drawn into the housing (110) may be sterilized by ultraviolet rays emitted from the germicidal lamp (140) mounted inside the housing (110). Ultraviolet rays emitted from the germicidal lamp (140) may be prevented from leaking into the cooling duct (60) through the inlet (111) by the blocking rib (113).

[0149] A blocking rib (113) may be provided in each of the first housing (120) and the second housing (130) adjacent to the inlet (111). The blocking rib (113) may include a first blocking rib (116) formed in the first housing (120). The first blocking rib (116) may be formed to extend downward from the upper wall of the first housing (120).

[0150] The blocking rib (113) may include a second blocking rib (117) formed in the second housing (130). The second blocking rib (117) may be formed to extend upward from the lower wall of the second housing (130).

[0151] The first blocking rib (116) and the second blocking rib (117) may be formed at different positions based on the direction of air flow flowing into the inlet (111). The first blocking rib (116) may be formed in front of the second blocking rib (117). That is, the second blocking rib (117) may be formed closer to the inlet (111) than the first blocking rib (116). Since the first blocking rib (116) and the second blocking rib (117) are formed at different positions based on the direction of air flow flowing into the inlet (111), the sum of the lengths of the first blocking rib (116) and the second blocking rib (117) may be formed to be greater than the height of the inlet (111). Accordingly, ultraviolet rays emitted from the sterilizing lamp (140) can be completely blocked from flowing into the cold air duct (60) through the inlet (111) by the first blocking rib (116) and the second blocking rib (117).

[0152] As illustrated in Fig. 11, the housing (110) may include a blocking rib (113) that prevents ultraviolet rays emitted from the germicidal lamp (140) from leaking out of the housing (110) through the inlet (111). Air drawn into the housing (110) may be sterilized by ultraviolet rays emitted from the germicidal lamp (140) mounted inside the housing (110). Ultraviolet rays emitted from the germicidal lamp (140) may be prevented from leaking into the cooling duct (60) through the inlet (111) by the blocking rib (113).

[0153] A blocking rib (113) may be provided in each of the first housing (120) and the second housing (130) adjacent to the inlet (111). The blocking rib (113) may include a first blocking rib (118) formed in the first housing (120). The first blocking rib (118) may be formed to extend downward from the upper wall of the first housing (120).

[0154] The blocking rib (113) may include a second blocking rib (119) formed in the second housing (130). The second blocking rib (119) may be formed to extend upward from the lower wall of the second housing (130).

[0155] The first blocking rib (11) and the second blocking rib (119) may be formed at different positions based on the direction of air flow flowing into the inlet (111). The second blocking rib (119) may be formed in front of the first blocking rib (118). That is, the first blocking rib (118) may be formed closer to the inlet (111) than the second blocking rib (119). Since the first blocking rib (118) and the second blocking rib (119) are formed at different positions based on the direction of air flow flowing into the inlet (111), the sum of the lengths of the first blocking rib (118) and the second blocking rib (119) may be formed to be greater than the height of the inlet (111).
