A drum penetration hole (311) connecting the tub body (21) and the internal space of the drum body (31) may be provided on the circumference and bottom surface of the drum body (31).

[0057] The bottom surface of the drum body (31) may further include a stirring part (33) that is rotatable within the drum body and forms a water flow or stirs clothes.

[0058] The drum body (31) and the stirring unit (33) can be rotated by a drum driving unit. The drum driving unit may be provided to include a stator (34) that is fixed to the bottom surface of the tub body (21) to form a rotating magnetic field, a rotor (35) that rotates by the rotating magnetic field, a drum shaft (37) that penetrates the tub body (21) and is fixed to the drum body (31), and a stirring shaft (36) that penetrates the drum shaft (37) and connects the rotor (35) and the stirring unit (33).

[0059] In order to control the coupling of the drum shaft (37) and the rotor (35), the drum drive unit may be provided with a coupler (38) and an actuator (39). The actuator (39) is a means for controlling the position of the coupler (38), and the coupler (38) may be provided to reciprocate between a first point and a second point by the actuator (39). In this case, the first point may be set as a point where the coupler (38) connects the drum shaft (37) and the rotor (35), and the second point may be set as a point where the coupler (38) separates the drum shaft (37) and the rotor (35).

[0060] The above-mentioned clothing treatment device (100) may be equipped with a detergent supply device (detergent supply unit, D) that supplies detergent to the tub body (21). The detergent supply device (D) may be equipped to move detergent to the tub body (21) using water supplied from the water supply unit (25) (the water supply unit may be equipped to supply water to the tub body through a path provided inside the detergent supply device).

[0061] As shown in FIG. 3, the detergent supply device (D) may be provided to include a housing (4) that guides water supplied from the water supply unit (25) to the tub body (21), a drawer (6) that provides a space for storing detergent and can be withdrawn from the housing (4), and a pump (7, 8) that moves the detergent stored in the drawer (6) into the housing (4).

[0062] As illustrated in Fig. 4, the detergent supply device (D) may be fixed to the cabinet cover (12). As illustrated in Fig. 5, the cabinet cover (12) may be provided with a first region (121) and a second region (122, rear space) divided by a partition wall (123). The first region (121) may be a front space of the cabinet cover (12), and the inlet (125) may be provided in the first region (121), and the second region (122) may be a rear space of the cabinet cover (12), and the detergent supply device (D) and the water supply unit (25) may be provided to be located in the second region (122).

[0063] The above bulkhead (123) may be provided with a bulkhead penetration hole (124), and the bulkhead penetration hole (124) may be provided to penetrate the bulkhead (123) and connect the inlet (125) and the second region (122).

[0064] The above-mentioned clothing treatment device (100) may be provided with a support body (127) that is fixed to the cabinet cover (12) so as to be positioned in the second area (122) and supports the housing (4) of the detergent supply device. In this case, the water supply unit (25) may be provided to include a water supply pipe (251) and a valve (252) that controls the opening and closing of the water supply pipe according to a control signal of a control unit (not shown).

[0065] The above valve (252) is provided with a first valve (252a) and a second valve (252b) fixed to the support body (127), and the water supply pipe (251) may be provided with a first water supply pipe (251a) connecting the first valve (252a) and a first water supply source (not shown), and a second water supply pipe (251b) connecting the second valve (252b) and a second water supply source (not shown).

[0066] The first water supply pipe (251a) and the second water supply pipe (251b) may be provided to supply water of the same temperature to the detergent supply device (D), or may be provided to supply water of different temperatures to the detergent supply device (D). In the former case, the first water supply source and the second water supply source will be the same water supply source. However, in the latter case, the first water supply source may be set as a water supply source that supplies cold water, and the second water supply source may be set as a water supply source that supplies hot water.

[0067] The support body (127) is provided with a support body through-hole (128), and the support body through-hole (128) may be provided to be connected to the partition wall through-hole (124) to guide the housing (4) to the upper surface of the support body (127). Accordingly, the housing (4) may be seated on the support body (127) by being inserted into the partition wall through-hole (124) and the support body through-hole (128) (may be located in the second region).

[0068] The above housing (4) may be provided to include a first chamber (41) that provides a space in which the drawer (6) is accommodated, and a second chamber (42) that receives detergent from the pump (7, 8).

[0069] The second chamber (42) is provided to provide a space separated from the first chamber (41). FIG. 5 illustrates an example where the second chamber (42) is located outside the first chamber (41). That is, the second chamber (42) may be provided as a space that protrudes from the rear surface of the first chamber (41) in the direction in which the drawer (6) is inserted (-Z-axis direction) but has a smaller volume than the first chamber. However, the second chamber (42) is connected to the first chamber (41) through a connecting passage (49).

[0070] If the second chamber (42) is provided to be located outside the first chamber (41), the volume of the drawer (6) can be increased (the amount of detergent that the drawer can store can be increased), and if the volume of the second chamber (42) is set to be small, the possibility of the detergent supplied from the pump (7, 8) remaining inside the second chamber (42) can be minimized. The reason that the space in the interior of the housing (4) where the detergent can remain is small is because the possibility of all the detergent inside the second chamber (42) being discharged to the first chamber (41) through the water supply unit (25) is increased.

[0071] The above housing (4) is provided with a flow path forming part (5), and the flow path forming part (5) is a means for forming flow paths (51, 52) that guide water supplied from the water supply part (25) to the first chamber (41) and the second chamber (42).

[0072] In order to supply water to the above-described water pipes (51, 52), the housing (4) may be provided with a first water inlet (417) and a second water inlet (418). The first water inlet (417) may be connected to the first valve (252a), and the second water inlet (418) may be provided to be connected to the second valve (252b). FIG. 5 illustrates an example of the water inlets (417, 418) in which, when the housing (4) is mounted on the support body (127), the first water inlet (417) is connected to the first valve (252a), and the second water inlet (418) is connected to the second valve (252b).

[0073] The above drawer (6) provides a space for storing detergent and can be provided so that it can be withdrawn from the first chamber (41).

[0074] As shown in FIG. 6, the drawer (6) provides a space for storing detergent and may be provided to include a body (61, drawer body) inserted into the first chamber (41), a cover (62, drawer cover) fixed to the body to form an upper surface of the drawer, and a panel (63, drawer panel) fixed to the front surface of the body (61) and exposed to the outside of the first chamber (41).

[0075] The above body (51) may be provided with a storage unit that provides a space for storing detergent, a discharge port that discharges the detergent in the storage unit to the outside of the body (51), and a discharge valve that controls the opening and closing of the discharge port.

[0076] As shown in Fig. 7, the housing (4) may be provided with the first chamber (41), the second chamber (42), and the flow path forming portion (5).

[0077] The first chamber (41) may be formed by a lower surface (412) supported by the support body (127), a first side surface (413) and a second side surface (414) provided on both sides of the lower surface, an upper surface (411) positioned above the lower surface by the two side surfaces (413, 414), and a rear surface (415).

[0078] The front surface of the first chamber (41) is provided as an open surface that provides a space for the body (61) of the drawer (6) to enter and exit, and a chamber discharge port (416) for discharging the fluid inside the first chamber (41) to the outside of the first chamber (such as a tub inlet) may be provided on the lower surface (412). To facilitate the discharge of the fluid inside the first chamber (41) to the outside (to minimize the possibility of the fluid remaining), the lower surface (412) may be provided as a sloped surface that slopes downward toward the chamber discharge port (416).

[0079] The first water supply port (417) and the second water supply port (418) are provided on the rear surface (415), and the second chamber (42) may be provided as a space protruding from the rear surface (415) toward the direction in which the drawer (5) is inserted (-Z-axis direction).

[0080] The second chamber (42) is connected to the first chamber (41) through the connecting passage (49) provided to penetrate the rear surface (415). It is preferable that the bottom surface of the second chamber (42) be positioned higher than the bottom surface of the first chamber (41) so that the fluid inside the second chamber (42) can be naturally drained. The second chamber (42) is connected to the pump (7, 8) through the first supply pipe (421) and the second supply pipe (422).

[0081] The above-mentioned euro-forming part (5) may be provided with a first euro body (5a) that forms a euro (first euro, 51) inside the first chamber (41), and a second euro body (5b) that forms a euro (second euro, 52) inside the second chamber (42).

[0082] The first euro body (5a) may be provided as a board fixed to the inside of the first chamber (41), and the second euro body (5b) may be provided as a board protruding from the edge of the first euro body (5a) toward the inside of the second chamber (42).

[0083] The first euro body (5a) may be fixed to the upper surface (411) to form the inner upper surface of the first chamber (41), and the second euro body (5b) may be positioned between the bottom surface and the upper surface of the second chamber (42) to divide the inside of the second chamber into an upper space and a lower space.

[0084] The edges of the second euro body (5b) may be provided so as to be in contact with all the inner surfaces of the second chamber (42). In this case, the upper space and the lower space will be completely separated spaces.

[0085] Meanwhile, as illustrated in FIG. 8, at least one of the edges constituting the edge of the second euro body (5b) may be provided so as not to contact the inner surfaces of the second chamber (42), in which case the upper space and the lower space will become interconnected spaces.

[0086] The first flow path (51) provides a path for water to move along the width direction (X-axis direction) of the first chamber (41). The first flow path (51) may be provided as a groove in which the upper surface of the first flow body (5a) is bent in a direction away from the upper surface (411) of the first chamber (-Y-axis direction). In this case, a step (515) will be formed in the first flow body (5a), so that the bottom surface (51a) of the first flow path (51) will be positioned at a point lower than the upper surface of the first flow body (5a).

[0087] In order to determine whether the detergent stored in the drawer (6) is supplied to the tub body (21), the detergent supply device (D) may further be equipped with a supply detection unit (91).

[0088] The above supply detection unit (91) may be provided with two electrodes (911, 912) fixed to the housing (4) and positioned in the connection path (49). The first electrode (911) and the second electrode (912) of the supply detection unit constitute a current detection circuit (a circuit capable of determining whether current is flowing). It is preferable that the first electrode (911) and the second electrode (912) be arranged so as to be spaced apart from each other along the width direction (X-axis direction) of the connection path within the connection path (49).

[0089] When water or detergent is supplied to the second chamber (42), the fluid inside the second chamber (42) moves to the first chamber (41) through the connecting passage (49). When the water or detergent moves along the connecting passage (49), the two electrodes (911, 912) will be connected by the fluid moving along the connecting passage (49).

[0090] The electrical resistance value when the two electrodes (911, 912) are connected by water will be different from the electrical resistance value when the two electrodes (911, 912) are connected by a mixture of water and detergent. Therefore, the control unit (not shown) will be able to determine whether detergent is supplied to the tub body (21) by monitoring the current value of the current detection circuit.

[0091] A guide rib (491) is provided to guide the flow of water or detergent to the supply detection unit (91), thereby increasing the ease of detection of current through the supply detection unit (91).

[0092] During the process in which the detergent or water supplied to the second chamber (42) moves through the connecting passage (49), the surface of the electrodes (911, 912) of the supply detection unit (91) may become contaminated due to water stains, the detergent component remaining due to long-term non-use solidifying, contamination by organic detergent, etc., making it difficult to detect the current of the water or detergent. Therefore, by concentrating the water or detergent on the two electrodes (911, 912), the surface of the two electrodes (911, 912) may be cleaned, thereby increasing the reliability of the current value by the supply detection unit (91).

[0093] The above guide rib (491) is sufficient to guide water or detergent flowing in the second chamber (42) to the two electrodes (911, 912), and its shape is not limited.

[0094] As illustrated in FIG. 9, water inside the first flow path (51) is discharged to the first chamber (41) through the first outlet (512) and the second outlet (514). The first outlet (512) may be provided with a plurality of holes arranged along the width direction (X-axis direction) of the first chamber on the left side of the connecting flow path (49) (the left side of the second flow path forming portion, the left side of the second flow path), and the second outlet (514) may be provided with a plurality of holes arranged along the width direction (X-axis direction) of the first chamber on the right side of the connecting flow path (49) (the right side of the second flow path forming portion, the right side of the second flow path).

[0095] As shown in Fig. 10, the second flow path (52) is branched from the first flow path (51) and is provided to guide water inside the first flow path (51) to the second chamber (42).

[0096] As shown in FIGS. 11 and 12, the second flow path (52) may be provided to include a second flow path outlet (525) provided to penetrate the second flow body (5b), a first branch flow path (521a) provided in the second flow body (5b) to guide water of the first flow path (51) into the second chamber (42), and a second branch flow path (522) provided in the second flow body (5b) to connect the first flow path (521) and the second flow path outlet (525).

[0097] The above second euro outlet (525) may be provided as a hole that penetrates the second euro body (5b) and connects the upper space of the second chamber (42) and the lower space.

[0098] The first branch flow path (521) and the second branch flow path (522) can be distinguished by a guide (523, first guide) provided in the second branch flow body (5b).

[0099] The first guide (523) may be provided as a wall protruding from the second flow body (5b) toward the upper surface of the second chamber (42). In this case, the first guide (523) may be provided as a wall extending from the first flow path (51) toward the inside of the second chamber (42) (extending along the insertion direction of the drawer, extending along the -Z-axis direction).

[0100] The second branch channel (522) may be provided to connect the first branch channel (521) and the first channel (41) so that water that has flowed into the second channel (52) but has not been discharged to the second chamber (42) through the second channel outlet (525) can be resupplied to the first channel (51).

[0101] In this case, the second flow path (52) may further include a guide (524, second guide) positioned between the first flow path (51) and the second flow path outlet (525) to form a boundary between the first flow path (51) and the second branch flow path (522).

[0102] The second guide (524) is a means for guiding water flowing into the second branch channel (522) to be supplied to the second channel outlet (525). The second guide (524) may be provided as a wall that protrudes from the second channel body (5b) toward the upper surface of the second chamber (42) and extends along the edge of the first channel (51).

[0103] Meanwhile, in order to allow water that was not discharged to the second chamber (42) through the second flow outlet (525) to be supplied to the first flow path (41), the upper end (free end) of the second guide (524) must be provided so as not to contact the upper surface of the second chamber (42). That is, it is preferable that the upper end (free end) of the second guide (524) be provided so as to be located between the bottom surface of the first flow path (41) and the upper end of the first guide (523).

[0104] In order to facilitate the supply of water from the first flow path (51) to the second flow path (52), it is preferable that the bottom surface (51a) of the first flow path be positioned at a higher point than the bottom surface of the second flow path (52).

[0105] An example is shown in which the bottom surface of the first flow path (51) is positioned at a higher point than the bottom surface of the first branch flow path (521), and the bottom surface of the first branch flow path (521) is positioned at a higher point than the bottom surface of the second branch flow path (522).

[0106] In order to minimize water remaining inside the second flow path (52) and to guide the water inside the second flow path (52) to the second flow path outlet (525), the second branch flow path (522) may be provided with a downwardly inclined slope toward the second flow path outlet (525).

[0107] When the above pump (7, 8) is operated, the detergent stored in the drawer (6) will be supplied to the second chamber (42) through the first supply pipe (421) and the second supply pipe (422), and the detergent inside the second chamber (42) will move to the first chamber (41) through the connecting pipe (49) when water is supplied to the second flow path (52).

[0108] When the edge of the second flow body (5b) is provided so as not to contact the inner surface of the second chamber (42), some of the water inside the first branch flow path (521) will move (F1) to the second flow path outlet (525) through the second branch flow path (522), and the remainder will move (F2) to the bottom surface of the second chamber (42). Therefore, the detergent supply device (D) will be able to minimize detergent remaining inside the second chamber (42).

[0109] An example of the above-described flow path forming part (53) is illustrated in Fig. 12. Referring to Fig. 10, the flow path forming part (5) inserted into the housing (4) can receive water through the first water supply port (417) and the second water supply port (418) provided on one side of the first chamber (41).

[0110] Water supplied through the above water supply port (417, 418) is supplied to the first flow path (51) of the flow path forming part (5), and water moving along the first flow path (51) can be transferred to the second flow path (52). Water flowing into the second flow path (52) can be supplied to the connecting flow path (49) through the second chamber (42) and pass through the supply detection part (91). Therefore, the flow path forming part (5) can be equipped with an induction guide (53) that induces the flow of water from the first flow path (51) to the second flow path (52) in order to measure the current value of the supply detection part (91).

[0111] The above-mentioned induction guide (53) may be provided in the form of a streamlined rib that is connected at one end to the step (515) and curved in the direction of the water path from the first flow path (51) to the second flow path (52) at the other end. The induction guide (53) may be provided so as to guide the water in the first flow path (51) to the second flow path (52) and may not be restricted by its shape.

[0112] The second flow path (52) may be formed to extend from a flow connection portion (517) branching from the first flow path (51) toward the second chamber (42).

[0113] The above-mentioned euro connection part (517) may be provided on one side of the first passage (51) as a place where the connection point where the water of the second guide (524) and the first passage (51) moves to the second passage (52) is extended.

[0114] The above water supply port (417, 418) can supply water to the first flow path (41) on one side based on the flow path connection part (517). The flow path forming part (5) can include a first direction flow path (511) located in a first direction (D1) on one side based on the flow path connection part (517) of the first flow path (511) and a second direction flow path (513) located in a second direction (D2) on the other side based on the flow path connection part (517) of the first flow path (511).

[0115] The flow direction of water supplied from the above water supply unit (417, 418) to one side of the first flow path (51) may be the second direction (D2).

[0116] Accordingly, since the hydraulic pressure is concentrated in the second direction (D2), the amount of water flowing in the first direction (D1) may be relatively smaller than the amount of water flowing in the second direction (D2). Accordingly, the flow path forming part (5) may include a first direction guide (54) that guides the water supplied to the first direction flow path (511) to be transferred in the first direction (D1).

[0117] The first outlet (512) may be formed in the first directional flow path (511), and the second outlet (514) may be formed in the second directional flow path (513).

[0118] The first direction guide (54) may be formed in a shape that induces water to be discharged through the first outlet (512). For example, water flowing around the first outlet (512) may be guided to the first outlet (512) to move the water to the first chamber (41) through the first outlet (512).

[0119] The above first outlet (512) may be provided with a plurality of holes as described above, and in this case, the first direction guide (54) may be formed at each of the plurality of first outlets (512).

[0120] The first flow path (51) may extend in the width direction of the housing (4). That is, the first direction (D1) and the second direction (D2) may be either the leftward or rightward direction of the housing (4), respectively.

[0121] The first discharge hole (512) and the second discharge hole (514) may be arranged in a row along the width direction of the housing (4). The first discharge hole (512) and the second discharge hole (514) may be provided in a semicircular shape curved toward the center of the first flow path (51) on one side where the second flow path (52) branches off from the first flow path (51).

[0122] A portion of the first outlet (512) and the second outlet (514) located close to the above-mentioned euro connection (517) may be removed so that the flow rate moving to the second euro (52) increases.

[0123] In the case where the first discharge port (512) is provided with a plurality of holes, the cross-sectional area becomes larger as it goes from the first direction (D1) to the second direction (D2), so that water can be discharged in the second direction (D2) rather than in the first direction (D1) of the first direction flow path (511).

[0124] In the first flow path (51), the direction of movement of water can flow from the first direction (D1) to the second direction (D2), and the cross-sectional area of ​​the first outlet (512) is formed to be larger than the cross-sectional area of ​​the second outlet (514), so that the distribution of water flowing into the first chamber (42) through the first outlet (512) and water flowing into the first chamber (41) through the second outlet (514) can be controlled.

[0125] The above-mentioned flow path forming part (5) may include a pressure reducing part (55) that reduces the pressure or amount of water moving in the second direction (D2) in the second direction flow path (513).

[0126] When the pressure of the water moving in the second direction (D2) of the second direction flow path (513) is strong, water may overflow to the end of the second direction (D2) of the second direction flow path (513), causing water to leak through the second direction (D2) of the housing (4). Therefore, a pressure reducing portion (55) having a breakwater structure that reduces the hydraulic pressure of water is formed at the end of the second direction (D2) of the second direction flow path (513), thereby preventing water leakage.

[0127] The above pressure reducing portion (55) may be provided with a plurality of streamlined ribs convex in the second direction (D2) at the end of the second direction flow path (513) in the second direction to reduce the flow rate of water. A drain hole (55a) is formed in the pressure reducing portion (55) to discharge water flowing into the pressure reducing portion (55) to the first chamber (41), thereby removing water accumulated in the pressure reducing portion (55).

[0128] The bottom surface (51a) through which the water of the first channel (51) flows is provided as a plane parallel to the ground, thereby expanding the flow area of ​​the first channel (51) and reducing the flow velocity and hydraulic pressure of the water flowing in the first channel (51), thereby minimizing the amount of water leaking into both ends of the first channel.

[0129] Another embodiment of the flow path forming part (5) is illustrated in Fig. 13. The first outlet (512) may be formed to be offset from the first directional flow path (511) in the second direction (D2), and the second outlet (514) may be formed to be offset from the second directional flow path (513) in the first direction (D1). Water flowing through the first flow path (51) may be concentrated toward the central portion where the flow path connecting part (517) is located. Accordingly, the amount of water discharged through the second flow path outlet (525) of the second flow path (52) may be increased, making it easier to measure the current value of the supply detection part (91).

[0130] The lower surface (412) of the first chamber (41) may have a slope angle such that the height of the remaining surfaces excluding the lower surface and the lower surface of the fan shape that spreads out as it goes in the withdrawal direction of the drawer (6) is set higher. In this case, if water is concentrated and discharged toward the rear center of the first chamber (41), the water may easily flow through the lower surface of the fan shape. Therefore, in order to flow water through the lower surface, the first outlet (512) and the second outlet (514) may be arranged toward the center of the first chamber to assist the flow of water.

[0131] Fig. 14 illustrates another embodiment of the above-described flow path forming part (5). A blocking wall (56) that blocks the movement of water may be formed at the second direction (D2) end of the second direction flow path (513) of the above-described flow path forming part (5).

[0132] The above-mentioned blocking wall (56) is provided with a plurality of walls that are perpendicular to the direction of movement of water through the first flow path (51) and protrude upward, thereby blocking water flowing in the second direction (D2). Accordingly, water leaking through the second direction (D2) can be minimized.

[0133] The above-mentioned barrier wall (56) may be provided with a barrier wall drain hole (56a) for draining water that has flowed beyond the barrier wall (56). The barrier wall drain hole (56a) may be provided in the form of an auxiliary hole interposed between each wall and / or a single hole penetrating each barrier wall. Accordingly, water that has flowed beyond the barrier wall (56) can be discharged into the first chamber (41).

[0134] Fig. 15 illustrates another embodiment of the above-described flow path forming part (5). The first flow path (51) may be provided in a shape in which only one side from which the second flow path (52) branches is open.

[0135] The first channel (51) may be extended from the step (515) in the direction of the second chamber (42) to shield the upper surface of the first channel (51), or the first channel (51) may be provided to be recessed in the width direction in the first channel body (5a).

[0136] In the above-described case, a part of the first euro body (5a) may be provided as a first euro cover (516) that shields the upper surface of the first euro (51).

[0137] The above-mentioned flow path forming part (5) may include a guide flow path (57) that is connected to the first flow path (51) at the end of the second direction (D2) of the first flow path (51) and is orthogonal to the extension direction of the first flow path (51). For example, the first flow path (51) may extend in the width direction of the housing (4), and the guide flow path (59) may extend in the length direction of the housing.

[0138] The above guide channel (59) is provided to have a downward slope from the first chamber (41) toward the second chamber (42), so that water flowing through the guide channel (59) can be discharged to the first chamber (41) through a drain hole provided in the first channel or the guide channel (59).

[0139] Figures 16 and 17 illustrate a flow prevention part (58) formed in the euro-forming part (5) and a flow prevention part insertion groove (416) formed in the housing (4) to which the flow prevention part (58) is coupled.

[0140] The first flow path (51) extends in the width direction of the housing (4) to form a water movement path, and the first flow path (51) may be formed at both ends in the direction of extension with a flow prevention member (58) inserted into the housing (4) to prevent water from moving.

[0141] When water moves in the width direction of the housing (4), which is the extended end of the first flow path (51), water may leak through the housing (4). Therefore, if the width direction gap between the housing (4) and the flow path forming part (5) is completely blocked by the flow prevention part (58), the aforementioned leakage can be minimized.

[0142] The above-mentioned prevention insertion groove (416) may be provided in a form in which the flow prevention portion (58) can be inserted or completely fused, and may be provided in a form in which the flow of water at both ends in the width direction of the flow path forming portion (5) can be completely blocked.

[0143] The detergent supply device and clothing treatment device described above are merely preferred embodiments, and therefore the scope of the rights of the present application is not limited to the above-described embodiments.
