For example, the first injection port (951) of the first cleaning nozzle (95) and the second injection port (981) of the second cleaning nozzle (98) may be arranged to face the rotational axis of the first filter (310).

[0153] For example, the first injection port (951) of the first cleaning nozzle (95) may include a shape extending approximately in a vertical direction (Z direction). For example, the second injection port (981) of the second cleaning nozzle (98) may include a shape extending approximately in a vertical direction (Z direction). However, the present disclosure is not limited to the examples described above. For example, the first injection port (951) may include a shape extending approximately along the circumferential direction of the first filter (310). For example, the second injection port (981) may include a shape extending approximately along the circumferential direction of the first filter (310). For example, the extension length of the first injection port (951) and the extension length of the second injection port (981) may be the same or different. For example, at least one of the first injection port (951) or the second injection port (981) may include various shapes such as a straight line, a curved line, a circle, or a polygon.

[0154] For example, the first cleaning nozzle (95) may include one first injection port (951) or may include a plurality of first injection ports (951). For example, the plurality of first injection ports (951) may be configured with a plurality of holes. When the first cleaning nozzle (95) includes a plurality of first injection ports (951), the shapes of each of the plurality of first injection ports (951) may be configured to be the same or different. When the first cleaning nozzle (955) includes a plurality of first injection ports (951), the shapes of some of the plurality of first injection ports (951) may be configured to be different from the shapes of other some of the first injection ports (951).

[0155] For example, the second cleaning nozzle (98) may include one second injection port (981) or may include a plurality of second injection ports (981). For example, the plurality of second injection ports (981) may be configured with a plurality of holes. When the second cleaning nozzle (98) includes a plurality of second injection ports (981), the shapes of each of the plurality of second injection ports (981) may be configured to be the same or different. When the second cleaning nozzle (98) includes a plurality of second injection ports (981), the shapes of some of the plurality of second injection ports (981) may be configured to be different from the shapes of other some.

[0156] In the drawing, an example is shown in which the dishwasher (1) includes a first cleaning nozzle (95) and a second cleaning nozzle (98), but the present disclosure is not limited thereto. The dishwasher (1) may include one cleaning nozzle or may include three or more cleaning nozzles.

[0157] For example, the dishwasher (1) may include only one of the first cleaning nozzle (95) and the second cleaning nozzle (98). If the dishwasher (1) includes only the first cleaning nozzle (95), the second cleaning nozzle (98) and its related components (e.g., the second guide pipe (96), the second flow valve (97), the second flow path (992)) may be omitted. If the dishwasher (1) includes only the second cleaning nozzle (98), the first cleaning nozzle (95) and its related components (e.g., the first guide pipe (93), the first flow valve (94), the first flow path (991)) may be omitted.

[0158] For example, the dishwasher (1) may further include at least one additional cleaning nozzle (not shown) in addition to the first cleaning nozzle (95) and the second cleaning nozzle (98). For example, the dishwasher (1) may further include an additional flow path for guiding water pumped by the circulation pump (61) to the additional cleaning nozzle and an additional flow path valve for opening or covering the additional flow path. The additional flow path may be partitioned from the first flow path (991) and the second flow path (992), or may branch from at least one of the first flow path (991) or the second flow path (992). The additional cleaning nozzle may be positioned so as not to interfere with the first cleaning nozzle (95) and the second cleaning nozzle (98). The additional cleaning nozzle may spray water toward the upper, lower, or middle region of the first filter (310), as needed. For example, the first cleaning nozzle (95) and the additional cleaning nozzle may spray water toward the lower portion of the first filter (310), and the second cleaning nozzle (98) may spray water toward the upper portion of the first filter (310). For example, the first cleaning nozzle (95) may spray water toward the lower portion of the first filter (310), and the second cleaning nozzle (98) and the additional cleaning nozzle may spray water toward the upper portion of the first filter (310).

[0171] The filter assembly (30) may include a first filter (310). The first filter (310) may be disposed within the water storage chamber (711). The first filter (310) may be detachable from the water storage chamber (711). The first filter (310) is detachably mountable to the sump housing (71).

[0172] The first filter (310) may be provided to filter water flowing into the water storage chamber (711). The first filter (310) may be provided to filter water flowing within the water storage chamber (711). The first filter (310) may be provided to filter water passing through the second filter (320) and / or the third filter (330), which will be described in detail below. For example, the first filter (310) may be provided to filter out foreign substances having a relatively smaller size than the second filter (320) and the third filter (330). For example, the first filter (310) may be provided to filter out foreign substances having a smaller size than foreign substances filtered out by the second filter (320) and the third filter (330). For example, the first filter (310) may include a microfilter. However, the present disclosure is not limited to the above-described example, and it is sufficient for the first filter (310) to be able to filter out foreign substances contained in water, and there is no limitation on the size of foreign substances filtered by the first filter (310).

[0173] Water flowing into the water storage chamber (711) can flow from the inside of the first filter (310) to the outside of the first filter (310). As the water passes through the first filter (310), foreign substances contained in the water can be captured by the first filter (310). The foreign substances contained in the water can be captured on the inner surface of the first filter (310). The foreign substances contained in the water can attach to the inner surface of the first filter (310). The foreign substances filtered by the first filter (310) can accumulate on the inner surface of the first filter (310). The water passing through the first filter (310) can be water from which foreign substances have been removed. The water passing through the first filter (310) can be sprayed to the tub (12) or circulated to the water storage chamber (711).

[0174] The first filter (310) may be arranged to surround the second filter (320). The first filter (310) may be arranged to cover at least a portion of the outer surface of the second filter (320). For example, the first filter (310) may have a generally hollow cylindrical shape.

The second filter (320) is removably mountable to the sump housing (71).

[0178] The second filter (320) may be provided to filter foreign substances contained in water flowing from the tub (12) to the sump (70). The second filter (320) may be provided to filter foreign substances having a relatively larger size than the first filter (310). For example, the second filter (320) may be provided to filter foreign substances having a larger size than the foreign substances filtered by the first filter (310). For example, the second filter (320) may include a coarse filter. However, the present disclosure is not limited to the above-described example, and the second filter (320) is sufficient as long as it can filter foreign substances contained in water, and there is no limitation on the size of the foreign substances filtered by the second filter (320).

[0179] For example, the second filter (320) may include a filter body (321). At least a portion of the filter body (321) may be positioned inside the first filter (310). The filter body (321) may be insertable into a filter hole (332) of a third filter (330), which will be described in detail below.

[0180] For example, the second filter (320) may include a hollow portion (322). The hollow portion (322) may be formed inside the filter body (321). The hollow portion (322) may include a hollow hole (322a). A filter shaft (370), which will be described in detail below, may be inserted into the hollow portion (322). The hollow portion (322) may extend along the extension direction of the filter shaft (370). The hollow portion (322) may have a shape extending approximately along the vertical direction (Z direction).

[0181] For example, the second filter (320) may include a flange portion (323). The flange portion (323) may protrude from the outer surface of the filter body (321). The flange portion (323) may extend along the circumference of the filter body (321). The flange portion (323) may be configured to pressurize an elastic member (3100) to be described in detail below.

[0182] For example, the second filter (320) may include a fixed rib (324, see FIG. 19). The fixed rib (324) may correspond to a rib groove (333) of the third filter (330), which will be described in detail below. The fixed rib (324) may be accommodated in the rib groove (333). The fixed rib (324) may be coupled to the rib groove (333). Accordingly, while the first filter (310) rotates, the second filter (320) may be fixed to the third filter (330) and may not rotate.

[0183] The filter assembly (30) may include a third filter (330). The third filter (330) is detachably mountable to the tub (12). For example, the third filter (330) may be placed on the bottom (12b) of the tub (12) (see FIG. 3). The third filter (330) may be placed on the first filter (310).

[0184] The third filter (330) may be provided to filter foreign substances contained in water flowing from the tub (12) to the sump (70). The third filter (330) may be provided to filter foreign substances having a relatively larger size than the first filter (310). The third filter (330) may be provided to filter foreign substances having a relatively smaller size than the second filter (320). For example, the third filter (330) may be provided to filter foreign substances having a larger size than the foreign substances filtered by the first filter (310). For example, the third filter (330) may be provided to filter foreign substances having a smaller size than the foreign substances filtered by the second filter (320). For example, the third filter (330) may include a fine filter. However, the present disclosure is not limited to the above-described example, and it is sufficient for the third filter (330) to be able to filter out foreign substances contained in water, and there is no limitation on the size of foreign substances filtered by the third filter (330).

[0185] For example, the third filter (330) may include a filter body (331). The filter body (331) may have a roughly plate shape. The filter body (331) may include a material and / or a shape for filtering foreign substances contained in water. One side (331a) of the filter body (331) may be placed by a mounting portion (83) of the support plate (80). One side (331a) of the filter body (331) may be mounted on the mounting portion (83) of the support plate (80).

[0186] For example, the third filter (330) may include a filter hole (332). The filter hole (332) may be formed by penetrating the filter body (331). A second filter (320) may be inserted into the filter hole (332). For example, the size of the filter hole (332) may be smaller than the size of the flange portion (323) of the second filter (320).

[0187] For example, the third filter (330) may include a rib groove (333, see FIG. 19). The rib groove (333) may correspond to the fixed rib (324) of the second filter (320). The rib groove (333) may accommodate the fixed rib (324). The rib groove (333) may be coupled with the fixed rib (324). For example, the rib groove (333) may be formed by being cut from the filter hole (332). Thus, while the first filter (310) rotates, the second filter (320) may be fixed to the third filter (330) and may not rotate.

[0188] As described above, the ordinal numbers "first," "second," and "third" of the first filter (310), the second filter (320), and the third filter (330) do not limit their configuration. For example, the first filter (310), the second filter (320), and the third filter (330) may be referred to as filter (310), filter (320), and filter (330), respectively. For example, the first filter (310) may be referred to as the second filter (310), and the second filter (320) may be referred to as the first filter (320).

[0189] The filter assembly (30) may include a filter cover (340). The filter cover (340) may be provided to cover a portion of at least one filter (310, 320, and / or 330). This may prevent / block relatively large-sized foreign matter lumps from flowing into the storage chamber (711). The filter cover (340) may be detachably mounted on the inside of the second filter (320). The filter cover (340) may be provided to cover a portion of the inside of the second filter (320).

[0199] For example, the filter shaft (370) may include a first hook (373). The first hook (373) may protrude upward from a second end (371b) of the shaft body (371). The first hook (373) may be arranged to pass through the hollow portion (322) of the second filter (320) and be caught on an upper end (322b) of the hollow portion (322) (see FIG. 33). The first hook (373) may include a first hook body (3731) extending from the second end (371b) of the shaft body (371), and a first hook protrusion (3732) protruding from the first hook body (3731) and supported by the upper end (322b) of the hollow portion (322). The first hook protrusion (3732) may protrude in a direction substantially intersecting with the extension direction of the first hook body (3731).

[0200] For example, the filter shaft (370) may include a second hook (374). The second hook (374) may be spaced apart from the first hook (373). The second hook (374) may protrude upward from a second end (371b) of the shaft body (371). The second hook (374) may be arranged to pass through the hollow portion (322) of the second filter (320) and be caught on an upper end (322b) of the hollow portion (322) (see FIG. 33). The second hook (374) may include a second hook body (3741) extending from the second end (371b) of the shaft body (371), and a second hook protrusion (3742) protruding from the second hook body (3741) and supported by the upper end (322b) of the hollow portion (322). The second hook protrusion (3742) may protrude in a direction that roughly intersects the extension direction of the second hook body (3741). The second hook protrusion (3742) may protrude in a direction opposite to the protrusion direction of the first hook protrusion (3731).

[0201] For example, the first hook (373) and the second hook (374) may be arranged to be symmetrical about an axis in the vertical direction.

[0202] For example, the first hook (373) and the second hook (374) are elastically deformable.

[0203] For example, the filter shaft (370) may include a shaft groove (375). The shaft groove (375) may be formed between the first hook (373) and the second hook (374). A shaft fixer (390), which will be described in detail below, may be inserted into the shaft groove (375).

[0204] For example, the filter shaft (370) may include a first protrusion (3711) protruding from the outer surface of the filter shaft (370). The first protrusion (3711) may protrude from the shaft body (371). At least one first protrusion (3711) may be formed on the shaft body (371). Although FIG. 23 illustrates that the filter shaft (370) includes four first protrusions (3711), there is no limitation on the number of first protrusions (3711).

[0205] For example, the filter shaft (370) may include a first recessed portion (3712) provided on the outer surface of the filter shaft (370) so as to be adjacent to the first protrusion (3711). The first recessed portion (3712) may be a portion of the shaft body (371) in which the first protrusion (3711) is not formed. The first recessed portion (3712) may be a portion that is relatively sunken compared to the first protrusion (3711). However, the present disclosure is not limited thereto, and the first recessed portion (3712) may be sunken from the outer surface of the filter shaft (370), and the first protrusion (3711) may be interpreted as a portion that is relatively protruded compared to the first recessed portion (3712). In FIG. 23, the filter shaft (370) is illustrated as including four first recessed portions (3712), but there is no limitation on the number of first recessed portions (3712).

[0206] For example, both the first protrusion (3711) and the first recess (3712) may be provided in multiples, and the first protrusion (3711) and the first recess (3712) may be alternately arranged along the outer surface of the filter shaft (370).

[0207] The filter assembly (30) may include a rotating frame (380). The rotating frame (380) may be provided to connect the first filter (310) and the filter shaft (370). The rotating frame (380) may transmit the rotational force of the filter shaft (370) to the first filter (310). The rotating frame (380) may be provided to rotate by the filter shaft (370). The rotating frame (380) may be provided to be coupled to the filter shaft (370) and to rotate together with the filter shaft (370). The first filter (310) may be coupled to the rotating frame (380) and to rotate together with the rotating frame (380). The first filter (310) may receive the rotational force of the filter motor (350) through the filter shaft (370) and the rotating frame (380).

[0208] For example, the rotating frame (380) may include a filter fixing part (381). The filter fixing part (381) may be provided so as to be mountable to the lower portion of the first filter (310). The filter fixing part (381) may be detachably coupled to the lower portion of the first filter (310). The filter fixing part (381) may include a fixing groove (3811). A portion of the filter frame (311) of the first filter (310) may be inserted into the fixing groove (3811). For example, the fixing groove (3811) of the filter fixing part (381) may be provided so as to fix the lower frame portion (311b) and the side frame portion (311c) of the first filter (310).

[0209] For example, the rotating frame (380) may include a shaft fixing part (382). The shaft fixing part (382) may be connected to a filter fixing part (381). The shaft fixing part (382) may be provided to engage with an outer surface of a filter shaft (370). The shaft fixing part (382) may be provided to engage with a shaft body (371) of the filter shaft (370).

[0210] For example, the shaft fixing portion (382) may include a through-hole (3823) through which the filter shaft (370) passes. The through-hole (3823) may include a hollow shape.

[0211] For example, the shaft fixing portion (382) may include a second protrusion (3821) protruding from the inner surface of the through portion (3823). The second protrusion (3821) of the rotating frame (380) may be arranged to correspond to the first recessed portion (3712) of the filter shaft (370). Although the rotating frame (380) is illustrated in FIG. 24 as including four second protrusions (3821), there is no limitation on the number of second protrusions (3821).

[0212] For example, the shaft fixing portion (382) may include a second recessed portion (3822) provided on the inner surface of the through portion (3823) so as to be adjacent to the second protrusion (3821). The second recessed portion (3822) of the rotating frame (380) may be provided so as to correspond to the first protrusion (3711) of the filter shaft (370). The second recessed portion (3822) may be a portion of the through portion (3823) in which the second protrusion (3821) is not formed. The second recessed portion (3822) may be a portion that is relatively sunken compared to the second protrusion (3821). However, the present disclosure is not limited thereto, and the second recessed portion (3822) may be recessed from the inner surface of the through portion (3823), and the second protruding portion (3821) may be interpreted as a portion that protrudes relatively compared to the second recessed portion (3822). In FIG. 24, the rotating frame (380) is illustrated as including four second recessed portions (3822), but there is no limitation on the number of second recessed portions (3822).

[0213] For example, both the second protrusion (3821) and the second recess (3822) may be provided in multiples, and the second protrusion (3821) and the second recess (3822) may be alternately arranged along the inner surface of the through portion (3823).

[0214] The filter assembly (30) may include a shaft fixer (390). The shaft fixer (390) may be detachably coupled to the filter shaft (370). The shaft fixer (390) may be disposed between the first hook (373) and the second hook (374) of the filter shaft (370). The shaft fixer (390) may be provided to be coupled to a shaft groove (375) of the filter shaft (370). The shaft fixer (390) may be provided to be insertable into the shaft groove (375) of the filter shaft (370). As will be described in detail below, the shaft fixer (390) may prevent / inhibit the filter shaft (370) inserted into the hollow portion (322) of the second filter (320) from being separated from the hollow portion (322) of the second filter (320).

[0215] For example, the shaft fixer (390) may include a fixer body (390) and a hook groove (392) formed in the fixer body (390). The shaft fixer (390) may include the hook groove (392) so as to have a shape corresponding to the shape of the filter shaft (370). The hook groove (392) may include a first hook groove portion (3921) corresponding to a first hook (373). The first hook (373) may be inserted into the first hook groove portion (3921). The hook groove (392) may include a second hook groove portion (3922) corresponding to a second hook (374). The second hook (374) may be inserted into the second hook groove portion (3922).

[0216] For example, the rotating frame (380) may include a connecting frame (383) for connecting the filter fixing part (381) and the shaft fixing part (382). The connecting frame (383) may include a radially extended shape.

[0217] The filter assembly (30) may include an elastic member (3100). For example, the elastic member (3100) may include an elastic material.

[0218] The elastic member (3100) can reduce friction between the first filter (310) and another component adjacent to the first filter (310). The elastic member (3100) can be provided to guide the rotation of the first filter (310).

[0219] The elastic member (3100) may be provided to seal between the first filter (310) and another component adjacent to the first filter (310). The elastic member (3100) may be provided to eliminate a gap between the first filter (310) and another component adjacent to the first filter (310).

[0220] For example, although the drawing illustrates another configuration adjacent to the first filter (310) as a second filter (320) (e.g., see FIGS. 30 and 34), the present disclosure is not limited thereto. Depending on the configuration and / or configuration arrangement of the dishwasher (1), the other configuration adjacent to the first filter (310) may be the bottom (12b) of the tub (12) or the third filter (330). The other configuration adjacent to the first filter (310) may also be a configuration other than the configurations described above.

[0221] The elastic member (3100) is mountable to the first filter (310). The elastic member (3100) is detachably coupled to the first filter (310). The elastic member (3100) is detachably coupled to the upper portion of the first filter (310). For example, the elastic member (3100) may have a substantially ring shape to correspond to the shape of the first filter (310). Meanwhile, the elastic member (3100) may also be detachably coupled to another configuration adjacent to the first filter (310).

[0222] For example, the elastic member (3100) may include a first body portion (3110). The first body portion (3110) may be mounted on top of the first filter (310). The first body portion (3110) may include a first opening (3110a).

[0223] For example, the first body portion (3110) of the elastic member (3100) may include an inner wall portion (3112), an outer wall portion (3113) spaced apart from the inner wall portion (3112), and a connecting wall portion (3114) connecting the inner wall portion (3112) and the outer wall portion (3113). The first body portion (3110) may further include an extension wall portion (3115) extending from the lower end of the outer wall portion (3113) toward the inner wall portion (3112).

[0224] The inner wall portion (3112) may form a first opening (3110a). The inner wall portion (3112) may be provided to correspond to the inner surface of the first filter (310). The inner wall portion (3112) may be provided to face the inner surface of the first filter (310).

[0225] The outer wall portion (3113) may be provided to correspond to the outer surface of the first filter (310). The outer wall portion (3113) may be provided to face the outer surface of the first filter (310). The outer wall portion (3113) may extend downward from the second body portion (3120), which will be described in detail below.

[0226] The connecting wall portion (3114) may be provided to correspond to the upper portion of the first filter (310). The connecting wall portion (3114) may be provided to face the upper surface of the first filter (310).

[0227] For example, the first body portion (3110) of the elastic member (31000) may include an insertion groove (3111). The insertion groove (3111) may have a shape that is open downward so that the upper portion of the first filter (311) can be inserted. For example, the upper frame portion (311a) of the first filter (310) may be inserted into the insertion groove (3111). The insertion groove (3111) may be formed by an inner wall portion (3112), an outer wall portion (3113), and a connecting wall portion (3114). The insertion groove (3111) may be defined by the inner wall portion (3112), the outer wall portion (3113), and the connecting wall portion (3114). The insertion groove (3111) may be surrounded by an inner wall portion (3112), an outer wall portion (3113), and a connecting wall portion (3114).

[0228] For example, the elastic member (3100) may include a second body portion (3120). The second body portion (3120) may extend upward from the first body portion (3110). The second body portion (3120) may include a second opening (3120a) that is larger than the first opening (3110a). For example, the first opening (3110a) and the second opening (3120a) may include a circular shape, and a diameter (D2) of the second opening (3120a) may be larger than a diameter (D1) of the first opening (3110a). As will be described in detail below, the elastic member (3100) has a shape in which the second opening (3120a) is larger than the first opening (3110a), so that the protruding rib (3130) of the elastic member (3100) can be easily pressed.

[0229] For example, the elastic member (3100) may include a protruding rib (3130). The protruding rib (3130) may extend upward from the second body portion (3120). The protruding rib (3130) may extend upward at an angle from the second body portion (3120). The protruding rib (3130) may be arranged to be bent inwardly of the second opening (3120a). The protruding rib (3130) may be arranged to form a gap with the first body portion (3110). For example, the gap formed between the first body portion (3110) and the protruding rib (3130) may gradually increase inwardly of the second opening (3120a). Here, the gap may mean the shortest distance in the vertical direction (Z direction) between the first body part (3110) and the protruding rib (3130). For example, the second gap (g2) may be larger than the first gap (g1).

[0230] For example, the elastic member (3100) may include a space (S). The space (S) may be formed by a first body portion (3110), a second body portion (3120), and a protruding rib (3130). The space (S) may be a space surrounded by the first body portion (3110), the second body portion (3120), and the protruding rib (3130). For example, the space (S) may be defined by a connecting wall portion (3114), the second body portion (3120), and the protruding rib (3130). The space (S) may extend along a circumferential direction of the elastic member (3100). The space (S) may include a gap formed between the first body portion (3110) and the protruding rib (3130). The space (S) may include a second opening (3120a). The space (S) may be referred to as an elastic groove (S).

[0231] Since the elastic member (3100) includes a space (S), the protruding rib (3130) of the elastic member (3100) can be easily pressed by another configuration adjacent to the first filter (310). As the protruding rib (3130) is pressed downward, the size of the space (S) can be varied. A detailed description thereof will be provided below.

[0232] Meanwhile, the elastic member (3100) may be referred to as a rotation guide member (3100).

[0233] The filter assembly (30) may include a sealing member (300). The sealing member (300) may prevent / reduce water leakage between the filter assembly (30) and the sump (70). The sealing member (300) may be disposed between the filter shaft (370) and the sump housing (71). For example, the sealing member (300) may have an approximately ring shape.

[0234] FIG. 30 is a side cross-sectional view taken along line A-A' of FIG. 3 according to various embodiments. FIG. 31 is a plan cross-sectional view taken along line B-B' of FIG. 30 according to various embodiments. FIG. 32 is a plan cross-sectional view taken along line C-C' of FIG. 30 according to various embodiments. FIG. 33 is an enlarged view of a drawing of a portion D of FIG. 30 according to various embodiments. FIG. 34 is an enlarged view of a drawing of a portion E of FIG. 30 according to various embodiments.

[0235] Referring to FIG. 30, the motor shaft (351) of the filter motor (350) can be inserted into one end of the filter shaft (370). The filter shaft (370) can pass through the shaft hole (718) and be placed inside the water storage chamber (711). The filter shaft (370) can be engaged with the rotating frame (380). The filter shaft (370) can be inserted into the hollow portion (322) of the second filter (320). The other end of the filter shaft (370) can pass through the hollow portion (322) and protrude from the hollow portion (322). The shaft fixer (390) can be coupled to the other end of the filter shaft (370). A predetermined gap (G) can be formed between the upper end of the rotating frame (380) and the lower end of the hollow portion (322). The hollow portion (322) may not be affected by the rotation of the rotating frame (380).

[0236] The first filter (310) can be rotated by the filter motor (350). The first filter (310) can receive the rotational force of the filter motor (350) from the filter shaft (370) and the rotational frame (380). The rotational force of the filter motor (350) can be transmitted to the filter shaft (370), and the rotational force of the filter shaft (370) can be transmitted to the rotational frame (380).

[0237] As the filter motor (350) rotates, the filter shaft (370) coupled to the motor shaft (351) of the filter motor (350) can rotate. The filter shaft (370) can be linked to the rotation of the filter motor (350). As the filter shaft (370) rotates, the rotary frame (380) engaged with the filter shaft (370) can rotate. The rotary frame (380) can be linked to the rotation of the filter shaft (370). As the rotary frame (380) rotates, the first filter (310) fixed to the rotary frame (380) can rotate. The first filter (310) can be arranged to rotate together with the rotary frame (380) while being fixed to the rotary frame (380). The first filter (310) can be linked to the rotation of the rotary frame (380). However, the present disclosure is not limited to the above, and the first filter (310) may also receive rotational power directly from the filter motor (350).

[0238] During the filter cleaning operation of the dishwasher (1), the first filter (310) may be arranged to rotate within the water storage chamber (711). During the filter cleaning operation of the dishwasher (1), the filter motor (350) may operate to rotate the first filter (310). For example, while at least one cleaning nozzle (95 and / or 98) sprays water toward the first filter (310), the first filter (310) may be arranged to rotate. As a result, the area of ​​the first filter (310) that comes into contact with the water sprayed from the at least one cleaning nozzle (95 and / or 98) may increase. The cleaning area of ​​the first filter (310) may be increased. The cleaning efficiency of the first filter (310) may be improved.

[0239] While the first filter (310) rotates, the second filter (320) may not rotate. For example, the filter motor (350), the filter shaft (370), the rotation frame (380), the shaft fixer (390), and the first filter (310) may be arranged to rotate together, but the second filter (320) may be arranged not to rotate together with the above-mentioned components.

[0240] Referring to FIG. 31, the rotating frame (380) may be provided to engage with the filter shaft (370). The inner surface of the through-hole (3823) of the rotating frame (380) may be provided to engage with the outer surface of the filter shaft (370). The inner surface of the through-hole (3823) of the rotating frame (380) may be provided to engage with the outer surface of the filter shaft body (371). The outer surface of the filter shaft (370) may interfere with the inner surface of the through-hole (3823) of the rotating frame (380). The filter shaft (370) may include a first protrusion (3711) and a first recess (3712). The rotating frame (380) may include a second protrusion (3821) and a second recess (3822). The second protrusion (3821) of the rotating frame (380) may correspond to the first recessed portion (3712) of the filter shaft (370). The second recessed portion (3822) of the rotating frame (380) may correspond to the first protrusion (3711) of the filter shaft (370). The second protrusion (3821) of the rotating frame (380) may be accommodated in the first recessed portion (3712) of the filter shaft (370). The first protrusion (3711) of the filter shaft (370) may be accommodated in the second recessed portion (3822) of the rotating frame (380). With this structure, as the filter shaft (370) rotates, the rotating frame (380) coupled to the filter shaft (370) may also rotate. For example, as the filter shaft (370) rotates by the filter motor (350), the first protrusion (3711), which is a component of the filter shaft (370), may also rotate. For example, the first protrusion (3711) may press the second protrusion (3712) in the rotational direction of the filter shaft (370) while rotating. Consequently, the rotation frame (380) may be arranged to be engaged with the filter shaft (370) and rotate together.

[0241] Referring to FIG. 32, the hollow portion (322) may not be engaged with the filter shaft (370). The outer surface of the filter shaft (370) may not interfere with the inner surface of the hollow portion (322). The hollow portion (322) may not include components corresponding to the first protrusion (3711) and the first recessed portion (3712). For example, the inner surface of the hollow portion (322) may be made of a smooth material. For example, the shaft fixer (390) may have a small frictional resistance by including a POM material. The hollow portion (322) may be fixed without rotating, and the filter shaft (370) and the shaft fixer (390) may be arranged to rotate within the hollow portion (322). Consequently, the second filter (320) may not rotate.

[0242] Additionally, the second filter (320) may include a fixed rib (324, see FIGS. 19 and 34), and the third filter (330) may include a rib groove (333, see FIGS. 19 and 34) corresponding to the fixed rib (324). As the fixed rib (324) is coupled to the rib groove (333), the second filter (320) may be fixed to the third filter (330) and may not rotate.

[0243] Referring to FIG. 33, the first hook (373) of the filter shaft (370) may protrude outside the hollow portion (322). The first hook (373) of the filter shaft (370) may be arranged to pass through the hollow portion (322) and be caught on the upper end (322b, see FIG. 32) of the hollow portion (322). The first hook (373) of the filter shaft (370) may be arranged to pass through the hollow portion (322) and interfere with the hollow portion (322). For example, the first hook protrusion (3732) of the first hook (373) may come into contact with the upper end (322b) of the hollow portion (322). The second hook (374) of the filter shaft (370) may protrude outside the hollow portion (322). The second hook (374) of the filter shaft (370) may be arranged to pass through the hollow portion (322) and be caught on the upper end (322b) of the hollow portion (322). The second hook (374) of the filter shaft (370) may be arranged to pass through the hollow portion (322) and interfere with the hollow portion (322). For example, the second hook protrusion (3742) of the second hook (374) may come into contact with the upper end (322b) of the hollow portion (322).

[0244] The shaft fixer (390) can be inserted into the shaft groove (375). The shaft fixer (390) can be positioned between the first hook (373) and the second hook (374). At least a portion of the shaft fixer (390) can be positioned inside the hollow portion (322).

[0245] The shaft fixer (390) can be coupled to the filter shaft (370) to maintain a gap between the first hook (373) and the second hook (374). The shaft fixer (390) can be coupled to the shaft groove (375) to maintain the first hook (373) and the second hook (374) in a state of being caught on the upper end (322b) of the hollow portion (322). The shaft fixer (390) can be arranged between the first hook (373) and the second hook (374) to prevent / suppress the second filter (320) and the filter shaft (370) from being separated.

[0246] For example, as the filter shaft (370) rotates, the first hook (373) and the second hook (374) may be deformed. The first hook (373) and the second hook (374) may be twisted due to shaking, vibration, etc. that occur when the filter shaft (370) rotates. Accordingly, the first hook (373) and the second hook (374) may move toward each other and toward the inside of the hollow hole (322a). The first hook (373) and the second hook (374) may be released from the upper end (322b) of the hollow portion (322). As a result, the second filter (320) and the filter shaft (370) may be separated. To prevent / reduce this, the filter assembly (30) may include a shaft fixer (390) inserted into the shaft groove (375) and the hollow portion (322) so as to be positioned between the first hook (373) and the second hook (374).

[0247] Referring to FIG. 34, an elastic member (3100) can be detachably coupled to an upper portion of a first filter (310). An upper portion of the first filter (310) can be inserted into an insertion groove (3111) of the elastic member (3100). A first body portion (3110) of the elastic member (3100) can be provided to surround an upper portion of the first filter (310). A second body portion (3120) of the elastic member (3100) can extend upward from the first body portion (320). The second body portion (3120) can extend upward from an outer wall portion (3113) of the first body portion (3110) and a connecting side wall (3114). A protruding rib (3130) of the elastic member (3100) can extend upwardly from the second body portion (3120) in an inclined manner.

[0248] The protruding rib (3130) of the elastic member (3100) may be arranged to be pressed by the second filter (320). The protruding rib (3130) of the elastic member (3100) may be arranged to be pressed downward by the flange portion (323) of the second filter (320). The protruding rib (3130) of the elastic member (3100) may be arranged to contact the flange portion (323) of the second filter (320).

[0249] The protruding rib (3130) of the elastic member (3100) may be configured to be elastically deformed when pressed by the second filter (320). The protruding rib (3130) may be configured to bend with respect to the second body portion (3120). The protruding rib (3130) may be bent toward the space (S) formed in the elastic member (3100). As the protruding rib (3130) is pressed, the space (S) formed in the elastic member (3100) may be variable. For example, since the elastic member (3100) has a shape including the space (S) (or the second opening (3120a), gap, see FIGS. 28 and 29), the protruding rib (3130) may be configured to be pressed by the second filter (320). One end of the protruding rib (3130) is fixed to the second body part (3120), and the other end of the protruding rib (3130) can be easily deformed by being pressed by another configuration in an unsupported state.

[0250] The elastic member (3100) may be configured to seal between the first filter (310) and the second filter (320) by the protruding rib (3130) of the elastic member (3100) being pressed by the second filter (320). As a result, foreign substances filtered by the first filter (310) and located inside the first filter (310) may not leak out to the outside of the first filter (310). Foreign substances filtered by the first filter (310) and located inside the first filter (310) may not escape between the first filter (310) and the second filter (320). For example, foreign substances accumulated inside the first filter (310) may escape into the space formed between the outer surface of the first filter (310) and the inner surface of the sump housing (71) and may not flow to the circulation pump (61). The elastic member (3100) can prevent / block / reduce foreign substances from circulating through the circulation pump (61). The elastic member (3100) can prevent / reduce re-contamination of the washing object (e.g., dishes) placed inside the tub (12) by foreign substances. The elastic member (3100) can improve the filtering efficiency of the filter assembly (30).

[0251] In addition, since the protruding rib (3130) of the elastic member (3100) is pressed by the second filter (320), the elastic member (3100) can be provided to reduce friction between the first filter (310) and the second filter (320). The protruding rib (3130) can assist the rotation of the first filter (310). The protruding rib (3130) can guide the rotation of the first filter (310). The protruding rib (3130) can prevent / suppress the rotation of the first filter (310) from being interfered with by other components. As a result, the first filter (310) can rotate smoothly by the elastic member (3100).

[0252] Meanwhile, in the drawing, the protruding rib (3130) of the elastic member (3100) is illustrated as being pressed by the flange portion (323) of the second filter (320), but the present disclosure is not limited thereto. For example, the protruding rib (3130) of the elastic member (3100) may be pressed by a configuration that is adjacent to the first filter (310) and positioned above the first filter (310). In some cases, the third filter (330) or the bottom (12b) of the tub (12) may be arranged to press the protruding rib (3130). Meanwhile, there is no limitation on the configuration as long as the configuration that pressurizes the protruding rib (3130) is arranged above the protruding rib (3130) and is arranged to come into contact with the protruding rib (3130).
