For example, the first flange (120) may have an outer diameter that increases as it protrudes forward from the first frame (110). For example, the groove (123) may be provided to have a truncated cone shape. For example, the inclination angle (α) of the groove (123) may be at least 1 degree or more. For example, the inclination angle (α) of the groove (123) may be approximately 4 degrees. However, the present disclosure is not limited to the above-described examples, and may vary depending on various design conditions / factors, etc. For example, the inclination angle (α) of the groove portion (123) may vary depending on the length of the groove portion (123) along the first direction (A) (or the second direction (B)), the distance between the first sealing protrusion (410) and the second sealing protrusion (420) of the sealing member (400), and / or the compression amount of the sealing member (400).

[0113] The groove (123) may include a first side (1231) adjacent to the first wall (121) and a second side (1232) adjacent to the second wall (122). The second side (1232) may be spaced apart from the first side (1231) along the second direction (B). For example, while the sealing member (400) is mounted on the first flange (120), the first side (1231) of the groove (123) may be provided to correspond with the first sealing protrusion (410) of the sealing member (400) to be described later.

[0115] The first flange (120) may include a first chamfer (125). The first chamfer (125) may be provided to taper from the second wall portion (122) in the second direction (B). The first chamfer (125) may be provided at the front end of the first flange (120). The second flange (220) of the second duct (200), which will be described later, may be smoothly docked to the first flange (120) by the first chamfer (125).

[0116] The first duct (100) may include a first inlet (130). Wash water may be introduced into the first frame (110) through the first inlet (130). The first inlet (130) may be connected to a sump (70). The first inlet (130) may be in communication with the sump (70). For example, the first inlet (130) may be formed in the first body (111).

[0117] The second duct (200) may include a second frame (210). The second frame (210) may form a path for the washing water to flow. The second frame (210) may be provided to guide the washing water provided from the first duct (100). The second frame (210) may be provided to guide the washing water provided from the first duct (100).

[0119] The second flange (220) may be provided to be connectable to the first flange (120). The second flange (220) may be provided to be dockable to the first flange (120). The second flange (220) may be connectable to the first flange (120) in a first direction (A). The second flange (220) may be dockable to the first flange (120) in a first direction (A).

[0120] As the second flange (220) is coupled to the first flange (120), the second flange (220) may be arranged to surround the first flange (120). While the second flange (220) is docked to the first flange (120), the second flange (220) may be arranged to cover the first flange (120). While the second flange (220) is docked to the first flange (120), the first flange (120) may be arranged to be positioned inside the second flange (220). For example, the inner surface (220a) of the second flange (220) may be arranged to face the outer surface (120a) of the first flange (120). For example, the inner surface (220a) of the second flange (220) may be arranged to surround the outer surface (120a) of the first flange (120). For example, the inlet hole (220h) of the second flange (220) may be larger than the outlet hole (120h) of the first flange (120).

[0121] For example, as the basket (52) secured to the second duct (200) is introduced into the tub (12), the second flange (220) may be arranged to dock to the first flange (120) (see FIGS. 3 and 4). For example, as the basket (52) secured to the second duct (200) is withdrawn from the tub (12), the second flange (220) may be arranged to undock from the first flange (120) (see FIGS. 3 and 4). For example, as the second flange (220) is docked to the first flange (120), at least a portion of the first flange (120) may be inserted into the interior of the second flange (220).

[0122] The second flange (220) may include a second chamfer (225). When the second flange (220) is coupled to the first flange (120), the second chamfer (225) may be provided to correspond to the first chamfer (125). The second chamfer (225) may be provided at the rear end of the second flange (220). The second flange (220) may be smoothly docked to the first flange (120) by the second chamfer (225).

[0123] The second duct (200) may include a second outlet (230). The second outlet (230) may be provided to discharge washing water guided by the second frame (210). The second outlet (230) may be connected to the spray unit (42). The second outlet (230) may be in communication with the spray unit (42). For example, the second outlet (230) may be formed on the lower side of the second frame (210).

[0124] The second duct (200) may include a check valve (240). The check valve (240) may prevent backflow of the wash water. The check valve (240) may prevent the wash water flowing from the first duct (100) toward the second duct (200) from flowing into the first duct (100). For example, the check valve (240) may allow the wash water to flow in the second direction (B). For example, the check valve (240) may restrict the wash water from flowing in the first direction (A). For example, the check valve (240) may be fixed to the second frame (210) by the second flange (220). For example, the check valve (240) may be detachably coupled to the second frame (210) and / or the second flange (220). For example, the check valve (240) may be provided integrally with the second frame (210) and / or the second flange (220).

[0125] The second duct (200) may include a basket fixing member (250) provided to fix a basket (52). The basket fixing member (250) may be formed on the frame (210). The basket fixing member (250) may include at least one fixing rib (251, 252, 253 and / or 254). For example, at least one fixing rib (251, 252, 253 and / or 254) may include a hook. For example, at least one fixing rib (251, 252, 253 and / or 254) may be provided to fix a wire constituting the basket (52).

[0126] A sealing member (400) may be provided to seal between a first duct (100) and a second duct (200). The sealing member (400) may be mounted on a first flange (120) of the first duct (100). When the second flange (220) is coupled to the first flange (220) while the sealing member (400) is mounted on the first flange (120), the sealing member (400) may seal between the first flange (120) and the second flange (220). The sealing member (400) may prevent washing water from leaking between the first flange (120) and the second flange (220). The sealing member (400) may include a ring shape.

[0127] The sealing member (400) may include a sealing body (430). The sealing body (430) may be mounted on the outer surface of the first flange (120). The sealing body (430) may be mounted in the groove (123) of the first flange (120). The sealing body (430) may be seated in the groove (123). The sealing body (430) may be fitted into the groove (123).

[0128] The sealing member (400) may include a first sealing protrusion (410). The first sealing protrusion (410) may protrude from the sealing body (430). The first sealing protrusion (410) may protrude from the sealing body (430) in a third direction (C), which is a radial direction of the sealing member (400). The first sealing protrusion (410) may have a shape extending along the circumferential direction of the sealing member (400). For example, the first sealing protrusion (410) may be formed on one side of the sealing member (400).

[0129] The sealing member (400) may include a second sealing protrusion (420). The second sealing protrusion (420) may be spaced apart from the first sealing protrusion (410). The second sealing protrusion (420) may protrude from the sealing body (430) in a third direction (C), which is a radial direction of the sealing member (400). For example, the second sealing protrusion (420) may have a shape extending along the circumferential direction of the sealing member (400). For example, the second sealing protrusion (420) may be formed on the other side of the sealing member (400). For example, the second sealing protrusion (420) may be formed on a side of the sealing member (400) opposite to the side on which the first sealing protrusion (410) is formed.

[0130] For example, the first sealing protrusion (410) and the second sealing protrusion (420) may be arranged symmetrically with respect to the vertical center line (V) of the sealing member (400). The first sealing protrusion (410) and the second sealing protrusion (420) may have the same shape. This can prevent the sealing member (400) from being incorrectly assembled to the first flange (120). For example, the user does not need to distinguish between the front and back of the first sealing protrusion (410) and the second sealing protrusion (420). For example, the sealing member (400) may be mounted on the first flange (120) so that the first sealing protrusion (410) is positioned behind the second sealing protrusion (420) (hereinafter, referred to as the first mounting state of the sealing member (400)), and the sealing member (400) may be mounted on the first flange (120) so that the second sealing protrusion (420) is positioned behind the first sealing protrusion (410) (hereinafter, referred to as the second mounting state of the sealing member (400). That is, both the first mounting state of the sealing member (400) and the second mounting state of the sealing member (400) may be correctly assembled states. However, the present disclosure is not limited to the above-described example, and the first sealing protrusion (410) and the second sealing protrusion (420) of the sealing member (400) may include various shapes in order to seal between the first duct (100) and the second duct (200).

[0131] The sealing member (400) may include a reinforcing portion (440). The reinforcing portion (440) may be formed between the first sealing protrusion (410) and the second sealing protrusion (420). The reinforcing portion (440) may protrude from the sealing body (430) between the first sealing protrusion (410) and the second sealing protrusion (420). For example, the reinforcing portion (440) may protrude from the sealing body (430) along a third direction (C) between the first sealing protrusion (410) and the second sealing protrusion (420). For example, the reinforcing portion (440) may have a shape extending along the circumferential direction of the sealing member (400). For example, the thickness of the reinforcing portion (440) along the third direction (C) may be smaller than the thickness of the first sealing protrusion (410) along the radial direction (C). For example, the thickness of the reinforcing portion (440) along the third direction (C) may be smaller than the thickness of the second sealing protrusion (420) along the radial direction (C). For example, the length by which the first sealing protrusion (410) protrudes from the sealing body (430) may be greater than the length by which the reinforcing portion (440) protrudes from the sealing body (430). For example, the length by which the second sealing protrusion (420) protrudes from the sealing body (430) may be greater than the length by which the reinforcing portion (440) protrudes from the sealing body (430). For example, the first sealing protrusion (410) and the second sealing protrusion (420) may be arranged to protrude further from the sealing body (430) than the reinforcing portion (440).

[0132] The reinforcing member (440) may be provided to reinforce the strength of the sealing member (400). The sealing member (400) may not be detached from the groove (123) due to a force (e.g., friction) that occurs when the second flange (220) is coupled to or separated from the first flange (120). Accordingly, the sealing member (400) may not be deformed due to a force (e.g., friction) that occurs when the second flange (220) is coupled to or separated from the first flange (120). The sealing member (400) may not be damaged by being crushed by other components when the second flange (220) is coupled to or separated from the first flange (120).

[0133] The first sealing protrusion (410) may be provided to protrude further from the sealing body (430) than the reinforcing portion (440). The second sealing protrusion (420) may be provided to protrude further from the sealing body (430) than the reinforcing portion (440).

[0134] The sealing member (400) may include a first notch portion (450). The first notch portion (450) may be provided adjacent to the first sealing protrusion (410). The first notch portion (450) may be formed between the first sealing protrusion (410) and the reinforcing portion (440). The first notch portion (450) may be provided to be recessed between the first sealing protrusion (410) and the reinforcing portion (440). For example, as the first sealing protrusion (410) and the reinforcing portion (440) protrude from the sealing body (430), the first notch portion (450) may be interpreted as a relatively recessed portion among the sealing body (430). Alternatively, for example, as the first notch portion (450) is recessed from the sealing body (430), the first sealing protrusion (410) and the reinforcing portion (440) may be interpreted as being relatively protruding portions of the sealing body (430). For example, the first notch portion (450) may include a curved shape. The first notch portion (450) may be referred to as a first recess portion (450).

[0135] The first sealing protrusion (410) may be provided with a first notch portion (450) to make it more flexible. The first sealing protrusion (420) may be provided with a bendable shape toward the first notch portion (450). As a result, the second flange (220) may be more smoothly coupled to or separated from the first flange (120).

[0136] The sealing member (400) may include a second notch portion (460). The second notch portion (460) may be provided adjacent to the second sealing protrusion (420). The second notch portion (460) may be formed between the second sealing protrusion (420) and the reinforcing portion (440). The second notch portion (460) may be provided to be recessed between the second sealing protrusion (420) and the reinforcing portion (440). For example, as the second sealing protrusion (420) and the reinforcing portion (440) protrude from the sealing body (430), the second notch portion (460) may be interpreted as a relatively recessed portion among the sealing body (430). Alternatively, for example, as the second notch portion (460) is recessed from the sealing body (430), the second sealing protrusion (420) and the reinforcing portion (440) may be interpreted as being relatively protruding portions of the sealing body (430). For example, the second notch portion (460) may include a curved shape. The second notch portion (460) may be referred to as a second recess portion (460).

[0137] The second sealing protrusion (420) may be provided with greater flexibility by the second notch portion (460). The second sealing protrusion (420) may be provided with the ability to bend toward the second notch portion (460). As a result, the second flange (220) may be more smoothly coupled to or separated from the first flange (120).

[0138] Meanwhile, the length (L1) of the sealing member (400) along the second direction (B) may be greater than the thickness (L2) of the sealing member (400) along the third direction (C). The length (L1) of the sealing member (400) along the first direction (A) may be greater than the thickness (L2) of the sealing member (400) along the third direction (C). Accordingly, the sealing member (400) may not easily come off from the groove (123) when mounted in the groove (123).

[0139] Fig. 13 is a cross-sectional perspective view of a portion of a duct assembly according to one embodiment. Fig. 14 is a cross-sectional view of a portion of a duct assembly according to one embodiment. Fig. 15 is an enlarged view of a portion of Fig. 14.

[0140] When the first sealing protrusion (410) and the second sealing protrusion (420) are symmetrical with respect to the vertical center line (V) of the sealing member (400), when the sealing member (400) is not mounted on the first flange (120), the first sealing protrusion (410) and the second sealing protrusion (420) are substantially the same and may not be distinguished from each other. However, when the sealing member (400) is mounted on the first flange (120), the first sealing protrusion (410) and the second sealing protrusion (420) may be distinguished from each other by the inclination of the first flange (120). Hereinafter, a case in which the first sealing protrusion (410) is positioned behind the second sealing protrusion (420) will be described as an example. If the second sealing protrusion (420) is positioned behind the first sealing protrusion (410), the description related to the first sealing protrusion below may be applied to the sealing protrusion (420), and the description related to the second sealing protrusion below may be applied to the sealing protrusion (410). That is, the description related to the first sealing protrusion below may correspond to the description of the sealing protrusion located behind among the two sealing protrusions (410, 420). The description related to the second sealing protrusion below corresponds to the description of the sealing protrusion located in front among the two sealing protrusions (410, 420).

[0141] Referring to FIGS. 13 to 15, the second flange (220) of the second duct (200) can be coupled to the first flange (120) of the first duct (100) equipped with a sealing member (400). The sealing member (400) can seal between the first flange (120) and the second flange (220). The sealing member (400) can prevent leakage of washing water between the first flange (120) and the second flange (220). For example, the sealing member (400) can seal between the outer surface (120a) of the first flange (120) and the inner surface (220a) of the second flange (220).

[0142] The first sealing protrusion (410) may be spaced apart from the second sealing protrusion (420) along the first direction (A). The second sealing protrusion (420) may be spaced apart from the first sealing protrusion (410) along the second direction (B). The second sealing protrusion (420) may be positioned in front of the first sealing protrusion (410). The first sealing protrusion (410) may be positioned behind the second sealing protrusion (420). While the second flange (220) is docked to the first flange (120), the second sealing protrusion (420) may be arranged to face the inner surface (220a) of the second flange (220) before the first sealing protrusion (410). For example, the first sealing protrusion (410) may protrude from the rear end of the sealing body (430), and the second sealing protrusion (420) may protrude from the front end of the sealing body (430).

[0143] The first sealing protrusion (410) may include a first inclined portion (411) that is provided to be tapered along a first direction (A). The second sealing protrusion (420) may include a second inclined portion (421) that is provided to be tapered along a second direction (B). Accordingly, when the second flange (220) is coupled to or separated from the first flange (120), interference between the sealing member (400) and the second flange (220) may be minimized. The second flange (220) may be smoothly docked to the first flange (120). The second flange (220) may be smoothly undocked from the first flange (120).

[0144] While the sealing member (400) is mounted on the first flange (120), the first sealing protrusion (410) may be provided adjacent to the first wall portion (121). While the sealing body (430) is mounted on the groove portion (123), the first sealing protrusion (410) may be provided adjacent to the first wall portion (121). While the sealing body (430) is mounted on the groove portion (123), the first sealing protrusion (410) may be provided adjacent to the first side (1231) of the groove portion (123). While the sealing body (430) is mounted on the groove portion (123), the first sealing protrusion (410) may be provided to correspond to the first side (1231) of the groove portion (123).

[0145] While the sealing member (400) is mounted on the first flange (120), the second sealing protrusion (420) may be provided adjacent to the second wall portion (122). While the sealing body (430) is mounted on the groove portion (123), the second sealing protrusion (420) may be provided adjacent to the second wall portion (122). While the sealing body (430) is mounted on the groove portion (123), the second sealing protrusion (420) may be provided adjacent to the second side (1232) of the groove portion (123). While the sealing body (430) is mounted on the groove portion (123), the second sealing protrusion (420) may be provided to correspond to the second side (1232) of the groove portion (123).

[0146] As described above, the first flange (120) of the first duct (100) may have a shape that widens along the second direction (B). The groove (123) of the first flange (120) may have an incline. The first flange (120) of the first duct (100) may include an approximately truncated cone shape. Accordingly, while the sealing member (400) is mounted on the first flange (120), the second sealing protrusion (420) may be provided to protrude further than the first sealing protrusion (410). For example, while the sealing body (430) is mounted on the groove (123) of the first flange (120), the second sealing protrusion (420) may be provided to protrude further than the first sealing protrusion (410) with respect to the horizontal center line (H) (or axial center line) of the sealing member (400). For example, while the sealing body (430) is mounted in the groove (123) of the first flange (120), the second sealing protrusion (420) may protrude further in the third direction (C) than the first sealing protrusion (410).

[0147] While the sealing member (400) is mounted on the first flange (120) and the second flange (220) is coupled to the first flange (120), the second sealing protrusion (420) may be arranged to contact the second flange (220). While the sealing body (430) is mounted on the groove (123) and the second flange (220) is coupled to the first flange (120), the second sealing protrusion (420) may be arranged to contact the second flange (220). While the sealing body (430) is mounted on the groove (123) and the second flange (220) is coupled to the first flange (120), the second sealing protrusion (420) and the inner surface (220a) of the second flange (220) may be arranged to contact each other. The second sealing protrusion (420) may interfere with the inner surface (220a) of the second flange (220). The second sealing protrusion (420) may be provided to seal between the first flange (120) and the second flange (220).

[0148] While the sealing member (400) is mounted on the first flange (120) and the second flange (220) is coupled to the first flange (120), the first sealing protrusion (410) may be arranged to be spaced apart from the second flange (220). While the sealing body (430) is mounted on the groove (123) and the second flange (220) is coupled to the first flange (120), a gap (g) may be arranged to be formed between the first sealing protrusion (410) and the second flange (220). While the sealing body (430) is mounted on the groove (123) and the second flange (220) is coupled to the first flange (120), a gap (g) may be formed between the first sealing protrusion (410) and the inner surface (220a) of the second flange (220). The first sealing protrusion (410) may be provided to be spaced apart from the inner surface (220a) of the second flange (220). The first sealing protrusion (410) may not come into contact with the inner surface (220a) of the second flange (220). The first sealing protrusion (410) may not interfere with the inner surface (220a) of the second flange (220).

[0149] For example, the first sealing protrusion (410) does not come into contact with the second flange (220), but may be provided in a kind of labyrinth seal shape to impede the flow of washing water between the first flange (120) and the second flange (220). For example, a vortex (500) may be generated around the first sealing protrusion (410), and due to the resistance of the vortex (500), the leakage of washing water around the first sealing protrusion (410) may be reduced.

[0150] In a related art, for example, a dishwasher may include a first duct, a second duct dockable to the first duct, and a sealing member for sealing between the first duct and the second duct. A basket may be fixed to the second duct. The sealing member may include at least two sealing protrusions that come into contact with the second duct. Accordingly, a large amount of friction may occur when the second duct is docked to or undocked from the first duct. That is, it may not be easy to couple the second duct to or separate the first duct. For example, a large amount of force may be required to separate the second duct from the first duct, and dishes stored in the basket may be impacted. When the second duct is separated from the first duct, dishes stored in the basket may fall over or break. In another related art, an O-ring may be used to seal between the first duct and the second duct. At this time, the O-ring can easily fall out of the groove formed in the first duct. To prevent the O-ring from falling out easily, the groove may be formed deeper. However, if the groove is formed deeper, the flow rate of the washing water guided by the first duct may decrease as the size of the first duct decreases. In the related art, as another example, the sealing member may be provided to be insert-molded with at least one duct. That is, the sealing member may be provided as an integral part with at least one duct. However, insert-molding is expensive compared to other methods, and if the sealing member is damaged, the entire part must be replaced.

[0151] In contrast, according to the present disclosure, the second sealing protrusion (410) of the sealing member (400) may be in contact with the second duct (200), but the first sealing protrusion (410) of the sealing member (400) may not be in contact with the second duct (200). Only one of the two sealing protrusions (410, 420) may be in contact with the second duct (200). As a result, friction occurring while the second duct (200) is docked to or undocked from the first duct (100) can be reduced. The second duct (200) can be smoothly coupled to the first duct (100) and smoothly separated from the first duct (100). When separating the second duct (200) from the first duct (100), a large force may not be required. When separating the second duct (200) from the first duct (100), the shock transmitted to the dishes stored in the basket (52) can be minimized. Accordingly, when separating the second duct (200) from the first duct (100), the dishes stored in the basket (52) may not fall over or break. For example, the length (L1) of the sealing member (400) may be relatively larger than the thickness (L2). Accordingly, the sealing member (400) may not easily come off from the groove (123) even when a force is generated when the second duct (200) is coupled to or separated from the first duct (100). In addition, the sealing member (400) may be detachably coupled to the first duct (100). If the sealing member (400) is damaged, only the sealing member (400) can be replaced without having to replace the entire duct assembly (80). Maintenance of the sealing member (400) is easy.

[0152] Fig. 16 is a cross-sectional view of a portion of a duct assembly according to one embodiment. Fig. 17 is an enlarged view of a portion of Fig. 16.

[0153] FIGS. 16 and 17 may illustrate a state in which the second flange (220) of the second duct (200) is not completely coupled to the first flange (120) of the first duct (100). For example, FIGS. 16 and 17 may illustrate a state in which the second flange (220) is not completely docked to the first flange (120). For example, FIGS. 16 and 17 may illustrate a state in which the second flange (220) has moved after being docked to the first flange (120). For example, FIGS. 16 and 17 may illustrate a state in which the second flange (220) has moved in the second direction (B) after being docked to the first flange (120) in the first direction (A).

[0154] When using the dishwasher (1), there may be cases where the first duct (100) and the second duct (200) are not completely coupled. For example, a user may operate the dishwasher (1) without fully inserting the basket (52) and the second duct (200) into the tub (12). For example, even after the second flange (220) is completely docked to the first flange (120) in the first direction (A), the second duct (200) may move in the second direction (B) due to the water pressure of the washing water.

[0155] Referring to FIGS. 16 and 17, even when the second flange (220) of the second duct (200) is not completely joined to the first flange (120) of the first duct (100), the second sealing protrusion (420) can be in contact with the second flange (220). Even when the second flange (220) of the second duct (200) is not completely joined to the first flange (120) of the first duct (100), the second sealing protrusion (420) can be provided to seal between the first duct (100) and the second duct (200) by making contact with the second flange (220). That is, even if the second flange (220) of the second duct (200) is not completely connected to the first flange (120) of the first duct (100), the second sealing protrusion (420) can prevent leakage of the washing water. Consequently, even if the user does not completely insert the basket (52) and the second duct (200) into the tub (12) or the second duct (200) moves away from the first duct (100) due to the water pressure of the washing water, the sealing effect of the sealing member (400) can be secured.

[0156] According to the present disclosure, among the two sealing protrusions (410, 420) of the sealing member (400), the second sealing protrusion (420) located in front may come into contact with the second flange (220). According to the present disclosure, among the two sealing protrusions (410, 420) of the sealing member (400), the first sealing protrusion (410) located in the back may not come into contact with the second flange (220). With this structure, the size of the second flange (220) of the second duct (200) can be configured to be relatively small. Since the size of the second flange (220) is relatively small, the size of the basket (52) can be relatively large. For example, since the basket (52) is configured so as not to interfere with the second flange (220), the size of the basket (52) can be influenced by the size of the second flange (220). Since the size of the basket (52) is relatively large, a large amount of dishes can be loaded into the basket (52). Consequently, the loading efficiency of the basket (52) may not be reduced. For example, when the first sealing protrusion (410) located at the rear of the two sealing protrusions (410, 420) of the sealing member (400) comes into contact with the second flange (220), the size of the second flange (220) may become relatively large. For example, with reference to FIG. 16, in order for the first sealing protrusion (410) and the second flange (220) to come into contact, the second flange (220) may need to have a shape that extends further in approximately the first direction (A). In this case, as the size of the second flange (220) increases, the size of the basket (52) fixed to the second duct (200) may decrease. Since the size of the basket (52) is relatively small, only a small amount of dishes can be loaded into the basket (52). Consequently, the loading efficiency of the basket (52) may be reduced.

[0157] In summary, according to the present disclosure, as the sealing member (400) is mounted on the first flange (120), the first sealing protrusion (410) does not contact the second flange (220) due to the inclination of the first flange (120), and the second sealing protrusion (420) can contact the second flange (220). As a result, friction between the second flange (220) and the sealing member (400) can be reduced. The second duct (200) and the basket (52) can be smoothly introduced into and / or withdrawn from the tub (12). Even when the second duct (200) is not completely connected to the first duct (100), the sealing member (400) can prevent leakage of washing water. The size of the basket (52) can be configured to be relatively large compared to the second flange (220), so that the loading efficiency of the basket (52) may not be reduced. The usability of the dishwasher (1) can be improved.

[0158] Referring to FIG. 17, the sealing member (400) may include a second notch portion (460) that is provided to be sunken between the second sealing protrusion (420) and the reinforcing portion (440).

[0159] Since the sealing member (400) has a second notch portion (460) adjacent to the second sealing protrusion (420), the second sealing protrusion (420) can be provided flexibly. The second sealing protrusion (420) can be provided to be bendable through the second notch portion (460). For example, the second sealing protrusion (420) can be bent toward the second notch portion (460). For example, the second sealing protrusion (420) can be bent toward the reinforcing portion (440).

[0160] Since the sealing member (400) includes the second notch portion (460), the second flange (220) of the second duct (200) can be docked more smoothly to the first flange (120) of the first duct (100). For example, while the second flange (220) is coupled to the first flange (120) in the first direction (A), the second sealing protrusion (420) can be provided to be bendable. For example, the second sealing protrusion (420) can be provided flexibly by the second notch portion (460). Friction occurring between the first flange (120) and the second flange (220) can be reduced, and the second flange (220) can be smoothly docked to the first flange (120). The sealing member (400) can be prevented from being detached from the groove (123) of the first flange (120) by friction generated while the second flange (220) is docked to the first flange (120). The sealing member (400) can be prevented from being detached from the groove (123) and moving toward the first wall (121) by being pressed by the second flange (220). In addition, the sealing member (400) can be prevented from being twisted by being pressed by the second flange (220) while the second flange (220) is docked to the first flange (120).

[0161] Since the sealing member (400) includes the second notch portion (460), the second flange (220) of the second duct (200) can be more smoothly undocked from the first flange (120) of the first duct (100). For example, while the second flange (220) is separated from the first flange (120) in the second direction (B), the second sealing protrusion (420) can be flexibly provided by the second notch portion (460). Friction occurring between the first flange (120) and the second flange (220) can be reduced, and the second flange (220) can be smoothly undocked from the first flange (120). By forming a second notch (460) around the second sealing protrusion (420), less force may be required when pulling the second flange (220) from the first flange (120).

[0162] In summary, as the second notch portion (460) is formed between the second sealing protrusion (420) and the reinforcing portion (440), a predetermined space can be secured between the second sealing protrusion (420) and the reinforcing portion (440). As a result, the second sealing protrusion (420) can move more flexibly, and the second duct (200) can be smoothly coupled to the first duct (100) and smoothly separated from the first duct (100).

[0163] FIG. 18 is a cross-sectional view of a portion of a duct assembly according to one embodiment.

[0164] Compared to the previously described sealing member (400), the sealing member (400a) illustrated in FIG. 18 may include only the second sealing protrusion (420). The sealing member (400a) may be substantially the same as the sealing member (400) except that it does not include the first sealing protrusion (410). When describing the sealing member (400a) in FIG. 18, the same reference numerals may be assigned to components that are substantially the same as those described previously, and a detailed description thereof may be omitted. For convenience of description, the second sealing protrusion (420) may be referred to as a sealing protrusion (420), and the second notch portion (460) may be referred to as a notch portion (460).

[0165] The sealing member (400a) may include a sealing body (430) that can be mounted on the outer surface of the first flange (120). The sealing body (430) can be detachably mounted in the groove (123) of the first flange (120).

[0166] The sealing member (400a) may include a sealing protrusion (420) protruding from the sealing body (430). The sealing member (400) may protrude from the sealing body (430) in a third direction (C), which is a radial direction of the sealing member (400). The sealing protrusion (420) may be provided to protrude further than the notch portion (460) toward the inner surface (220a) of the second flange (220). The sealing protrusion (420) may be provided to protrude further than the reinforcing portion (440) toward the inner surface (220a) of the second flange (220). The sealing protrusion (420) may be formed at the front end of the sealing member (400a).

[0167] While the sealing member (400a) is mounted on the groove (123) and the second flange (220) is docked to the first flange (120), the sealing protrusion (420) may be arranged to contact the second flange (220). The sealing protrusion (420) may contact the inner surface (220a) of the second flange (220). The sealing protrusion (420) may interfere with the inner surface (220a) of the second flange (220). The sealing protrusion (420) may prevent the washing water from flowing between the first flange (120) and the second flange (220). The sealing protrusion (420) may prevent the washing water from leaking between the first flange (120) and the second flange (220). The sealing member (400a) may include a reinforcing member (440). The reinforcing portion (440) may be positioned behind the sealing protrusion (420). The reinforcing portion (440) may protrude from the sealing body (430). For example, the reinforcing portion (440) may protrude from the sealing body (430) in the third direction (C). However, it may also be expressed that the reinforcing portion (440) is formed by forming at least a portion of the sealing body (430) to be relatively thick. For example, a portion of the sealing body (430) that is formed to have a predetermined thickness or more may be referred to as the reinforcing portion (440). The reinforcing portion (440) may be formed to reinforce the strength of the sealing member by being formed to have a predetermined thickness or more.

[0168] The sealing member (400a) may include a notch portion (460). The notch portion (460) may be positioned adjacent to the sealing protrusion (420). The notch portion (460) may be positioned behind the sealing protrusion (420). The notch portion (460) may be formed so that the sealing member (400a) is recessed between the sealing protrusion (420) and the reinforcing portion (440). However, it may also be expressed that the notch portion (460) is formed by forming at least a portion of the sealing body (430) relatively thinly. For example, a portion of the sealing body (430) that is formed to be less than a predetermined thickness may be referred to as the notch portion (460). Since the sealing member (400a) includes the notch portion (460), the sealing protrusion (420) may be formed more flexibly. In this way, the second duct (200) can be smoothly connected to the first duct (100) and smoothly separated from the first duct (100).

[0169] According to one embodiment, a dishwasher may include a tub (12); a first duct (100) provided to guide washing water inside the tub, the first duct including a first flange (120); a second duct (200) provided to guide washing water supplied from the first duct, the second duct including a second flange (220) that is connectable to the first flange in a first direction (A); and a sealing member (400) provided to seal between the first flange (120) and the second flange (220). The sealing member (400) may include a sealing body (430) that is mountable to an outer surface of the first flange. The sealing member (400) may include a first sealing protrusion (410) that protrudes from the sealing body. The sealing member (400) may include a second sealing protrusion (420) that is spaced apart from the first sealing protrusion in a second direction (B) opposite to the first direction and protrudes from the sealing body. The sealing member (400) may include a reinforcing portion (440) formed between the first sealing protrusion (410) and the second sealing protrusion (420). The sealing member (400) may include a notch portion (460) that is provided to be recessed between the second sealing protrusion (420) and the reinforcing portion (440).

[0170] While the second flange (220) is coupled to the first flange (120) in the first direction (A), the second sealing protrusion (420) may be provided to be bendable toward the notch portion (460).

[0171] The first flange (120) may include a first wall portion (121); a second wall portion (122) spaced apart from the first wall portion (121) along the second direction (B); and a groove portion (123) formed between the first wall portion and the second wall portion and in which the sealing body of the sealing member is mounted. The groove portion (123) may have a slope as it widens along the second direction.

[0172] The first sealing protrusion (410) may be provided so as to be adjacent to the first wall portion (121) while the sealing body is mounted in the groove portion. The second sealing protrusion (420) may be provided so as to be adjacent to the second wall portion (122) while the sealing body is mounted in the groove portion.

[0173] While the sealing body is mounted in the groove and the second flange is coupled to the first flange, the second sealing protrusion (420) may be arranged to come into contact with the inner surface of the second flange (220).

[0174] While the sealing body is mounted in the groove and the second flange is coupled to the first flange, a gap (g) may be formed between the first sealing protrusion (410) and the inner surface of the second flange (220).
