[0108] The upper surface (411) of the chamber forms the upper surface of the first supply passage (541), the rear surface (415) of the chamber forms the rear surface of the first supply passage (541), the groove formed in the flow body (54) forms the front surface and the bottom surface of the first supply passage (541), and the first side surface (413) of the chamber and the flow passage partition (546) may be provided to form both sides of the first supply passage (541).

[0109] As illustrated in FIG. 6, the branch flow path may be provided to include a first branch flow path (51) that guides water from the first supply flow path (541) to the first inlet (711a), and a second branch flow path (52) that guides water inside the first supply flow path (541) to the third inlet (713a).

[0110] The second branch flow path (52) may be provided as a groove in which the euro body (54) is concavely bent toward the lower surface (412) of the chamber. Water flowing into the second branch flow path (52) may be supplied to the third inlet (713a) through the second branch flow path discharge hole (521). The second branch flow path discharge hole (521) may be provided as a plurality of holes penetrating the euro body (54).

[0111] The first branch flow path (51) may be provided to include a connecting flow path (511) extending from the first supply flow path (541) toward the first inlet (711a), and a diffusion flow path (515) extending from the connecting flow path (511) and having a shape that surrounds the edge of the first inlet (711a).

[0112] The above connecting channel (511) may be formed by a first forming wall (512) extending from the first supply channel (541) toward the center of the first inlet (711a), and a second forming wall (513) extending from the first supply channel (541) toward the center of the first inlet (711a) and positioned at a point spaced apart from the first forming wall. The connecting channel (511) may be provided with a connecting channel discharge hole (514) for discharging water to the first inlet (711a).

[0113] In order to minimize water remaining inside the connecting passage (511), the bottom surface of the connecting passage (511) may be provided with a downward sloping surface toward the center of the first inlet (711a).

[0114] As illustrated in FIG. 7, the diffusion path (515) may be provided to guide water from the outlet of the connecting path (511) to the space between the first forming wall (512) and the edge of the first inlet (711a), and to the space between the second forming wall (513) and the edge of the first inlet (711a).

[0115] The above diffusion channel (515) may be provided in a shape that surrounds the first forming wall (512) and the second forming wall (513) and may include a first surface (516) positioned above the first inlet (711a), and a second surface (518) positioned along the edge of the first surface (516) and positioned above the first inlet (711a). A first diffusion channel discharge hole (517) may be provided on the first surface (516), and a second diffusion channel discharge hole (519) may be provided on the second surface (518).

[0116] In order to minimize water remaining inside the diffusion channel (515), the second surface (518) may be provided as a downwardly inclined surface toward the edge of the first surface (516). The first surface (516) may be provided as a horizontal surface, or may be provided as a downwardly inclined surface toward the connecting channel (511).

[0117] The first branch flow path (51) of the above-described structure not only supplies water to the center of the first storage unit (711) through the connecting flow path (511), but also supplies water from the edge of the first storage unit (711) to the center of the first storage unit (711) through the diffusion flow path (515), so that the problem of detergent remaining inside the first storage unit (711) can be minimized.

[0118] Meanwhile, if the pressure of the water supplied to the first water supply port (417) or the third water supply port (419) is high, the water discharged from the connecting passage (511) may not be supplied to the entire area of ​​the diffusion passage (515) and may be concentrated in the area located on the right side of Fig. 7. This phenomenon increases the possibility of detergent remaining in the first storage unit (711).

[0119] To minimize the above-described problem, at least one of the first forming wall (512) and the second forming wall (513) may be provided to supply water inside the connecting passage (511) to the diffusion passage (515) in an overflow manner.

[0120] That is, at least one of the gap between the upper end of the first forming wall (512) and the upper surface of the chamber (411) and the gap between the upper end of the second forming wall (513) and the upper surface of the chamber (411) may be provided to increase toward the center of the first inlet (711a).

[0121] This means that at least one of the upper end of the first forming wall (512) and the upper end of the second forming wall (513) can be provided to be inclined downward as it faces the first inlet (711a), and FIG. 6 illustrates an example in which the upper ends of both forming walls (512, 513) are provided to be inclined.

[0122] When the upper ends of the above-mentioned forming walls (512, 513) are provided in an inclined shape, a space is formed between the upper ends of the forming walls (512, 513) and the upper surface (411) of the chamber, so that some of the water moving from the inlet of the connecting passage (511) toward the outlet can move beyond the forming walls to the diffusion passage (515). Accordingly, the phenomenon of water concentrating in a portion of the diffusion passage (515) can be minimized.

[0123] Although not shown in the drawing, the first branch channel (51) may be provided with a communication hole for discharging water inside the connecting channel (511) to the diffusion channel (515). The communication hole may be composed of a plurality of holes penetrating the first forming wall (512) and a plurality of holes penetrating the second forming wall (513).

[0124] To facilitate the flow of water inside the first supply channel (541) into the branch channel (51, 52), the channel forming part (5) may further be provided with a guide (544, 545).

[0125] The above guide may be provided to include a first guide (544) protruding from the inlet of the first branch channel (51) toward the edge of the first supply channel (541), and a second guide (545) protruding from the inlet of the second branch channel (52) toward the edge of the first supply channel (541).

[0126] The detergent supply device (D) of the above-described structure can minimize detergent remaining in the drawer (7), but it is difficult to minimize detergent remaining inside the chamber (41).

[0127] In order to minimize detergent residue inside the chamber (41), the flow path forming part (5) may further be provided with a cleaning hole (543). As illustrated in FIG. 7, the cleaning hole (543) may be provided as a means for discharging water into the space between the rear surface (415) of the chamber and the rear surface of the drawer (7), and may be provided as a plurality of grooves or holes provided along the rear edge of the flow path body (54) (provided along the width direction of the chamber).

[0128] The detergent supply device (D) of the above-described structure has a possibility that water inside the first supply channel (541) or inside the second supply channel (542) cannot be supplied to the inlet (711a, 712a, 713a) of each storage unit and may leak into the chamber (41). This is because the euro body (54) is structured to be fixed to the upper surface (411) of the chamber.

[0129] In order to prevent water inside the supply path (541, 542) from leaking into the chamber (41) through the space formed between both sides of the euro body (54) and both sides (413, 414) of the chamber, the detergent supply device (D) may further be provided with a sealing portion (61, 62, 63). The sealing portion may be provided as a bonding surface that bonds the upper surface of the euro body (54) to the upper surface (411) of the chamber.

[0130] The above sealing portion may include a first joint portion (61) that prevents leakage of the first supply passage (541), and a second joint portion (62) that prevents leakage of the second supply passage (542).

[0131] The first joint (61) may be provided with a fusion surface extending from the rear surface (415) of the chamber toward the chamber discharge portion (416) along the edge of the first supply passage (541) and the edge of the first branch passage (51), and the second joint (62) may be provided with a fusion surface extending from the rear surface (415) of the chamber toward the chamber discharge portion (416) along the edge of the second supply passage (542).

[0132] Fig. 8 shows a perspective view of the housing (4), and Fig. 9 shows a view of the housing (4) viewed from the front (Z-axis).

[0133] The housing (4) may include an opening (42) formed on the front by the lower surface (412), the first side surface (413) and the second side surface (414) provided on both edges of the lower surface (412).

[0134] The receiving space (43) communicating with the above opening (42) can be formed by the inner surface (44) formed by the lower surface (412), the two side surfaces (413, 414) on both sides, and the rear surface (415).

[0135] Since the chamber discharge portion (416) through which the fluid inside the drawer (4) is discharged to the outside is provided on the lower surface (412) of the drawer forming the receiving space (43), the component received inside the receiving space (43) can be arranged so as not to interfere with the lower surface (412), at least the chamber discharge portion (416).

[0136] The above-mentioned receiving space (43) can accommodate the drawer (7) in which detergent or softener is stored. In order to maximize the detergent storage capacity of the drawer (7), the width of the drawer (7) can be formed to match the width of the receiving space (43).

[0137] The side wall portions (714) constituting both side walls of the drawer (7) can be supported by the first side surface (413) and the second side surface (414) among the inner surfaces (44) constituting the receiving space (43).

[0138] A support rib (441) for supporting the drawer (7) may be formed on the inner surface (44).

[0139] In order to increase the detergent storage capacity of the drawer (7), the drawer (7) may be extended in the front-back direction and accommodated in the housing (4). Accordingly, in order to stably support the drawer (7), the support rib (441) may be extended in the front-back direction.

[0140] The length from the support rib (441) to the lowermost part of the drawer (7) is formed to be shorter than the length from the support rib (441) to the lower surface (412), so that the bottom surface of the drawer (7) may not obstruct the flow of the solution discharged to the chamber discharge portion (416).

[0141] When the drawer (7) is pulled out and inserted in the front-back direction (Z direction) of the housing (4), it is supported in the left-right direction (X direction) by the first side wall (413) and the second side wall (414), and may move up and down (Y direction). Therefore, a support groove (442) may be formed on the upper portion of the support rib (441) to limit upward movement of the drawer (7) supported by the support rib (441).

[0142] Fig. 10 shows a perspective view of the euro-forming part (5), and Fig. 11 shows a view of the euro-forming part (5) as viewed from the front (Z).

[0143] When the first branch channel (51) is provided with the connecting channel (511) and the diffusion channel (515), as shown in FIG. 10, the first joint (61) can extend from the rear surface of the chamber toward the chamber discharge portion along the edge of the first supply channel (541) and the edge of the diffusion channel (515).

[0144] In order to prevent water in the first supply channel (541) from moving to the second supply channel (542) or water in the second supply channel (542) from moving to the first supply channel (541), the sealing portion may further include a third joint portion (63) extending from the rear surface (415) of the chamber toward the chamber discharge portion (416) to separate the first supply channel (541) and the second supply channel (542).

[0145] The first joint (61), the second joint (62), and the third joint (63) may be provided as a fusion surface that fuses the contact points of the euro body (54) and the housing (4) using heat or ultrasonic waves. The contact point of the housing (4) and the euro forming part (5) may extend to the front side of the upper surface (411) of the housing (a point adjacent to the opening (42)).

[0146] A stopper (55) may be formed in the housing (4) to prevent the drawer (7) from being withdrawn beyond a set distance unless a certain external force is applied. Since the stopper (55) is preferably arranged on the front side of the housing (4), it may be provided in a form extending from the flow path forming portion (5) toward the drawer (7).

[0147] Fig. 12 shows a perspective view of the drawer (7), and Fig. 13 shows a rear view of the drawer (7).

[0148] In the drawer (7), the first storage section (711), the second storage section (712), and the third storage section (713) are respectively separated and arranged in the left and right directions, and the first side (413) and the second side (414) of the housing (4) and the side wall section (714) of the drawer (7) can be formed to be in contact to facilitate detergent injection and expand storage capacity.

[0149] The above drawer (7) may include a flange portion (76) that protrudes toward the inner surface (44) of the housing (4) in order to be stably fixed to the housing (5).

[0150] The above flange portion (76) may be provided in a shape that is supported by the support rib (441). Preferably, the flange portion (76) may be provided in a tip shape that is supported upward by the support rib (441).

[0151] The drawer (7) can be set to have a distance and sensitivity for withdrawal and retraction from the housing (4), thereby preventing damage to the drawer (7) and leakage of internal detergent. A pressure projection (75) can be formed to set the withdrawal and retraction sensitivity and distance of the drawer (7).

[0152] The above-mentioned pressure projection (75) can be formed at a position that maximizes the storage capacity of the storage units (711, 712, 713) and does not interfere with the input ports (711a, 712a, 713c) of the storage units.

[0153] The above-mentioned pressure projection (75) may be formed on a pressure portion (74) that forms the rear surface of the storage portion (711, 712, 713) and protrudes rearward from a rear wall (715) disposed on the rear surface of the drawer (7). The pressure portion (74) may be formed to be smaller than the height and width of the drawer (7) to facilitate storage.

[0154] The flange portion (76) may be formed to extend from the side wall portion (714) to the pressurizing portion (74). In addition, the flange portion (76) may extend rearward from the rear surface of the drawer panel (73) to the pressurizing portion (74). Accordingly, the rigidity of the drawer (7) and the pressurizing portion (74) may be improved.

[0155] Fig. 14 illustrates the drawer (7) being introduced and withdrawn into the receiving space (43) of the housing (4) through the opening (42). Figs. 15 and 16 illustrate cross-sectional views taken along line B-B' of Fig. 14, and Fig. 17 illustrates a cross-sectional view taken along line A-A'.

[0156] At the rear of the first side (413) and the second side (414) of the housing (4), a recessed portion (48) configured to insert the pressing portion (74) and a through hole (45) in which a separate configuration that interferes with the pressing projection (75) inserted into the recessed portion (48) is fastened or fixed can be formed.

[0157] The above drawing 15 illustrates that the flange portion (76) is supported by the support rib (441).

[0158] The above flange portion (76) may include a first protrusion (761) extending toward one surface of the inner surface (44) where the support rib (441) is formed, and a second protrusion (762) extending from the first protrusion (761) toward the support rib (441) and making contact therewith.

[0159] The end of the second protrusion (762) may be formed so that the area of ​​the extended cross-section becomes smaller as it approaches the support rib (441). Accordingly, in the process of the drawer (7) being drawn into and drawn out of the housing (4), the friction between the support rib (441) and the flange portion (76) is minimized, thereby reducing the external force required for drawing out and drawing in, and at the same time, noise and vibration can be minimized by reducing the friction surface.

[0160] The above flange portion (76) can be supported by contacting the support rib (441) in a linear shape extending in the front-rear direction.

[0161] When the flange portion (76) protrudes in both directions (X direction) from the side wall portion (714), the flange portion (76) may extend along the front-back direction (Z direction) as described above. In this case, the end of the second protrusion (762) may be formed so that the width in the left-right direction (Y direction) becomes smaller as it gets closer to the support rib (441).

[0162] The second protrusion (762) includes a downward extension (7621) extending from the end of the first protrusion (761) toward the support rib (441) and a contact protrusion (7622) extending from the end of the downward extension (7621) and having a smaller area of ​​the cross-section extending from the end of the downward extension (7621) and further from the downward extension, and the flange portion (76) can be supported by contacting the support rib (441) through the contact protrusion (7622).

[0163] The drawer (7) is limited to be withdrawn only to a set distance from the housing (4) with an external force less than a certain amount by the pressure protrusion (75) and the stopper (55), etc., but the drawer (7) can be provided so that it can be completely withdrawn from the housing (4) when an opening force greater than a certain amount is applied for cleaning or replacement.

[0164] The above-mentioned pressure projection (75) protrudes upward or downward from the drawer (4) to limit the withdrawal setting distance of the drawer (4), but when a certain external force is applied, the restriction of the pressure projection (75) is released and the drawer (7) can be completely withdrawn from the housing (4). In this case, the movement displacement of the drawer (7) in the up-and-down direction (Y direction) can be at least greater than the protrusion length of the pressure projection (75). Therefore, a height-wise (Y direction) separation distance between the upper portion of the flange portion (76) and the support groove (442) can occur.

[0165] The length from the point where the support groove (44) is maximally indented to the point where the support rib (441) protrudes maximally can be set to be equal to or greater than the length at which the flange portion (76) protrudes maximally from the side wall portion (714). Accordingly, the side wall portion (714) is supported by the inner surface (44), so that the drawer (7) can be minimized from shaking left and right (X direction) in the housing (4).

[0166] In this case, the movement of the drawer (7) in the up-and-down direction (Z direction) may occur more significantly than the movement in the left-right direction (X direction). Therefore, the extension length of the second protrusion (762) may be formed to be shorter than the extension length of the first protrusion (761), and the area of ​​the extension cross-section of the downward extension (7621) may be formed to be larger than the area of ​​the extension cross-section of the first protrusion (761). Therefore, the pressure applied to the flange portion (76) may be minimized and the rotational force may be reduced, thereby preventing deformation of the flange portion (76).

[0167] The above contact protrusion (7622) may be arranged to be offset to one side in the left and right direction from the end of the downward extension portion (7621). Specifically, the one side may be a direction away from the side wall portion (714) on which each flange portion (76) is formed. Accordingly, the contact protrusion (7622) is provided in a form that supports both lateral directions of the drawer (7), so that the drawer (7) can be minimized from being tilted to one side in the left and right direction (X direction).

[0168] The upper side of the end from which the first protrusion (761) extends is formed to be curved in a chamfered shape, so that interference between the flange portion (76) and the inner surface (44) can be minimized even in the event of interference due to manufacturing errors, shrinkage, etc.

[0169] Fig. 16 illustrates another embodiment in which the flange portion (76) is supported by the support rib (441). The flange portion (76) may be provided in a form extending toward one side of the inner surface (44) on which the support rib (441) is formed.

[0170] The above flange portion (76) extends in the front-back direction (Z direction) and the entire extending lower surface can be supported by the support rib (441).

[0171] Accordingly, the flange portion (76) and the support rib (441) support the drawer (7) in the vertical direction (Y direction) relative to the housing, and at the same time, serve as a guide when moving in the forward and backward direction (Z direction), and limit the range of motion in the left and right direction (X direction) to stably fix the drawer (7) to the housing (4).

[0172] The above drawing 17 shows a side view of the drawer (7) being inserted into the housing (4).

[0173] The drawer (7) can be inserted and fixed into the housing (4) by the pressure elastic member (46) and the pressure projection (75) inserted into the through hole (45) of the housing (4).

[0174] Fig. 18 is a perspective view of the pressurized elastic portion (46), and Fig. 19 shows the pressurized projection (75). Hereinafter, based on this, the process of Fig. 17, in which the drawer (7) is inserted into and fixed to the housing (4), will be described.

[0175] The above-mentioned pressurized elastic part (46) may be detachably coupled to the interior of the housing (4) and may be provided to protrude toward one surface of the drawer (7) where the pressurized protrusion (75) is formed, so that when the drawer (7) is inserted into the chamber (41), it is pressurized and elastically deformed by the pressurized protrusion (75).

[0176] The above-mentioned pressure elastic member (46) may be provided so that at least a portion thereof overlaps with the pressure projection (75) along the front-back direction (Z direction).

[0177] In the process of the drawer (7) being inserted into the housing (4), the pressure projection (75) may move rearward while passing the pressure elastic member (46). That is, the pressure elastic member (46) may be arranged so that at least a portion of the pressure projection (75) overlaps with the pressure elastic member (46) in the vertical direction (Y direction).

[0178] When the drawer (7) is fully inserted into the housing (4), the maximum protrusion of the pressing projection (75) can be positioned behind the maximum protrusion of the pressing elastic portion (76). When the maximum protrusion of the pressing elastic portion (46) comes into contact with the pressing projection (75), it is pressed and elastically deformed, and when the maximum protrusion of the pressing projection (75) passes, it can be elastically restored.

[0179] A user can withdraw the drawer (7) from the housing (4) and pour detergent or softener into the storage section (711, 712, 713). The drawer (7) in which the detergent or softener is stored can be slid back into the housing (4), and at this time, the user can recognize the drawing-in status of the drawer (7) through the contact relationship between the pressing projection (75) and the pressing elastic section (46).

[0180] For example, when the user retracts the drawer (7) backward, the user can sense the contact between the pressure projection (75) and the pressure elastic member (46) and receive a predetermined pressure. When the drawer (7) is retracted a certain distance or more, the pressure transmitted to the user is rapidly reduced as the pressure projection (75) passes the catch elastic member (46), so the user can confirm that the drawer (7) is completely retracted into the housing (4).

[0181] When the restoring force of the above-mentioned pressure elastic part (46) is transmitted to the above-mentioned pressure projection (46), the drawer (7) that has been retracted to a point where the maximum protrusion of the above-mentioned pressure projection (75) passes the maximum protrusion of the above-mentioned pressure elastic part (46) can receive a moving force so that it is completely retracted into the above-mentioned housing (4).

[0182] Accordingly, the user feels the backlash and inserts the drawer (7) into the housing (4), and when the backlash is removed and the inductive force is transmitted, the user can confirm the stable insertion state of the drawer (7).

[0183] The above-mentioned pressurized elastic member (46) is manufactured separately from the housing (4) and can be detachably combined by sliding and inserting into the insertion hole (47) of the housing (4).

[0184] Since the above-mentioned pressurized elastic portion (46) corresponds to an elastic body that is deformed and restored by the pressurized projection (75), it can be formed of a material that is easier to deform and has superior elasticity than the material of the drawer (7) that has high rigidity.

[0185] The above-mentioned pressurized elastic portion (46) may include a forward inclined portion (461) extending rearward from one end (46a) and sloping downward as it gets further away from the one end (46a), and a rear inclined portion (462) extending rearward from an end of the forward inclined portion (461) to the other end (46b) and sloping upward as it gets further away from the one end (46a).

[0186] In the process of the drawer (7) being inserted into the housing (4), the pressure projection (75) presses the front inclined portion (461) to elastically deform the pressure elastic portion (46), and in the state in which the drawer (7) is inserted into the housing (4), the pressure projection (75) can be supported by contacting the rear inclined portion (462).

[0187] The above-mentioned forward slope (461) may have a longer and gentler slope than the above-mentioned rear slope (462). Therefore, during the insertion process of the drawer (7), the pressure elastic portion (46) transmits a relatively low rate of increase in reaction force to the pressure projection (75) so that excessive force is not required during the insertion process, and during the withdrawal process of the drawer (7), a relatively high rate of increase in reaction force is transmitted to the pressure projection (75) so that unintended withdrawal of the drawer (7) can be prevented.

[0188] The above-mentioned pressure projection (75) may include a downwardly inclined steep portion (752) extending rearward from the maximum protrusion and a horizontal portion (753) extending rearward in parallel from the steep portion (752).

[0189] The horizontal portion (753) is provided to be in contact with the pressurized elastic portion (46), and as the horizontal portion (753) and the pressurized elastic portion (46) come into contact, a constant reaction force is transmitted to the user, and as the maximum protrusion of the pressurized elastic portion (46) passes over the steep slope (752) and provides a strong reaction force, the user can intuitively sense that the introduction is almost complete.

[0190] The above-mentioned pressure projection (75) may include a fixing portion (751) that extends forward from the maximum protrusion and is inclined downward.

[0191] The above-mentioned pressure projection (75) receives a reaction force that restricts the insertion of the drawer (7) as the pressure elastic portion (46) passes the steep slope (752), and then, as the pressure elastic portion (46) passes the maximum protrusion of the pressure projection (75) and comes into contact with the fixing portion (751), it is restored, thereby receiving a force that supports the insertion of the drawer (7), so that the user can easily recognize that the insertion is complete.

[0192] The above fixed portion (751) may include a first inclined portion (7511) extending from the maximum protrusion of the pressing projection (75) at a first incline and a second inclined portion (7512) extending from the end of the first inclined portion (7511) at an angle at least greater than the first incline.

[0193] The second inclined portion (7512) may be provided to sharply protrude upward in the height direction (Y direction) from the upper surface of the pressurizing portion (74). When the drawer (7) is withdrawn and inserted from the housing (4), a force pushing in the front-back direction (Z direction) is generated on the pressurizing projection (75), so that the resistance is maximized by the second inclined portion (7512), and the rigidity of the pressurizing projection (75) can be increased.

[0194] The housing (4) may include the through hole (45) that opens toward the upper surface of the drawer (7). The pressurized elastic portion (46) may be provided such that at least a portion of the front inclined portion (461) and the rear inclined portion (462) protrudes toward the drawer (7) by penetrating the through hole (45).

[0195] The shape of the above through hole (45) may vary. One end (46a) and / or the other end (46b) of the pressurized elastic portion (46) may be fixed by being joined to the housing (4).

[0196] The maximum protrusion point of the above-mentioned pressure elastic member (46) can protrude toward the drawer (7) through the through hole (45). Therefore, the protrusion distance of the above-mentioned pressure elastic member (46) increases, so that it can be easily deformed or restored by being pressed by the above-mentioned pressure projection (75).

[0197] For example, when the pressure elastic part (46) protrudes downward from the bottom surface of the upper surface (411) of the housing (4), the maximum protrusion length of the pressure elastic part (46) increases, which may be advantageous for elastic deformation, when the pressure elastic part (46) protrudes so as to penetrate the through hole (45).

[0198] In one embodiment of the present invention, the one end (46a) and the other end (46b) of the pressurized elastic portion (46) are positioned on the opposite side of the drawer (7) with respect to the upper surface (411) of the housing (4), and the pressurized elastic portion (46) can be bent so that the front inclined portion (461) and the rear inclined portion (462) extending from the one end (46a) and the other end (46b) pass through the through hole (45).

[0199] The above-mentioned pressure elastic part (46) may include a hook part (463) that is fastened to the housing (4) when the above-mentioned pressure elastic part (46) is completely inserted by sliding into the above-mentioned insertion hole (47).

[0200] The above hook portion (463) is pressed and elastically deformed when inserted into the insertion hole (47), and is restored when the pressurized elastic portion (46) is completely inserted into the housing (4) through the insertion hole (47), thereby limiting movement so that the pressurized elastic portion (46) is not pulled out of the insertion hole (47).

[0201] For example, the above-mentioned pressurized elastic portion (46) is inserted into the insertion hole (47) from the end (46a) from the rear to the front, and the hook portion (463) may be provided to protrude upward from the pressurized elastic portion (47) and be elastically deformed when pressurized downward from the front.

[0202] Accordingly, when the pressurized elastic portion (46) is inserted from the rear to the front, the hook portion (463) protrudes upward from the upper surface of the pressurized elastic portion (46), and can be inserted into the insertion hole (47) by being pressed downward from the front.

[0203] The above-mentioned pressurized elastic portion (46) is provided with a hook portion receiving groove (4631) that can receive the hook portion (463) when it is elastically deformed, so that the height-wise width of the insertion hole (47) can be minimized.

[0204] Fig. 20 illustrates the euro-forming part (5) inserted into the housing (4). Fig. 21 illustrates a cross-sectional view taken along line C-C' of Fig. 20.

[0205] The above-mentioned flow path forming part (5) is fixed inside the housing (4) and arranged on the upper part of the drawer (7) so as to cause water supplied from the water supply port (417, 418, 419) to fall into the drawer (7). Therefore, it is preferable that the flow path forming part (5) be arranged inside the housing (4) so ​​as to face the upper surface of the drawer (7).

[0206] As described above, when the joints (61, 62, 63) extend to the front of the housing (4), the detergent storage capacity of the drawer (7) can be maximized or leakage can be effectively prevented. Accordingly, the stopper (55) that restricts the forward movement of the pressure projection (75) and prevents the drawer (7) from being pulled out more than a set distance and falling, etc., can be formed in the flow path forming portion (5).

[0207] It is sufficient that the above stopper (55) is provided in the cabinet (1) so as to protrude toward the drawer (7) from one side facing the drawer (7) inserted into the inlet (124).

[0208] In one embodiment of the present invention, the pressure projection (75) may be provided to protrude upward from the upper surface of the drawer (7), and the stopper (55) may be provided to protrude downward from a surface facing the upper surface of the drawer (7) toward the drawer (7).

[0209] The above stopper (55) may include a contact surface (552) that extends upwardly and slopes rearwardly to interfere with the pressure projection (75) during the process of the drawer (7) being withdrawn from the inlet (124) of the cabinet (1) or the opening (42) of the housing (4) by a set distance.

[0210] The above-mentioned pressure projection (75) is arranged parallel to the stopper (55) along the front-back direction (Z direction) of the cabinet (1), and when the drawer (7) is withdrawn from the cabinet (1) to a certain level or more, the contact surface (552) of the stopper (55) provides a counter force to the pressure projection (75) to limit the withdrawal.

[0211] At this time, the contact surface (552) is extended so as to slope upwardly toward the rear, so that as the pressure projection (75) is pulled forward, the strength of the reaction force increases, so that the user can detect that the pull-out is complete.

[0212] Therefore, it is preferable that the maximum protrusion of the stopper (75) be placed in front of the maximum protrusion of the pressure projection (75) when the drawer (7) is pulled out from the cabinet (1) by a set distance.

[0213] When the drawer (7) is pulled out, the center of gravity of the drawer (7) moves forward, and since the drawer (7) is not supported by the housing (4), the front part of the drawer (7) may sag downward. In this case, since the contact surface (552) presses the rear part of the drawer (7) downward, and the front part of the drawer (7) is supported upward, the sagging phenomenon of the drawer (7) can be prevented.

[0214] The above contact surface (552) may be formed in a curved shape whose slope increases as it approaches the maximum protrusion of the stopper (55). Accordingly, as the drawer (7) is withdrawn forward, the rate of increase in the reaction force transmitted by the stopper (55) to the pressure projection (75) increases, so that a sense of when the withdrawal is stopped can be clearly conveyed. In addition, as the contact surface (552) is formed in a curved shape concave upward, the reaction force applied by the stopper (55) to the pressure projection (75) when the drawer (7) is withdrawn is reduced, so that the drawer (7) can be withdrawn with a smaller opening force.

[0215] The above stopper (55) may further include a withdrawal portion (551) that extends forward from the contact surface (552) and slopes upward as it moves away from the contact surface (552).

[0216] The drawer (7) can be completely separated from the housing (4) for cleaning and replacement. In this case, if a force greater than the external force generated by the interference of the stopper (55) and the pressure projection (75) is applied to the drawer (7), the drawer (7) can be pulled out. Accordingly, when the drawer (7) is completely pulled out from the housing (4), the reaction force applied to the pressure projection (75) is reduced due to the pull-out portion (551), so that the user can detect that the drawer (7) is separated from the cabinet (1).

[0217] The above-mentioned withdrawal portion (551) may be provided in a curved shape with an incline that becomes steeper as it gets farther from the contact surface (552). Accordingly, when the drawer (7) is withdrawn by a set distance and the pressure projection (75) interferes with the withdrawal portion (551), the rate of decrease in the reaction force applied to the pressure projection (75) increases as the drawer (7) is withdrawn forward, so that the drawer (7) can be easily separated.

[0218] Figure 22 illustrates a process in which the pressure projection (75) and the stopper (55) interfere when the drawer (7) is pulled out from the housing (4).

[0219] The above-mentioned pressure projection (75) may be provided on the pressure portion (74) that extends from the side wall portion (714) of the drawer (7) and protrudes rearward from the rear wall (715).

[0220] The upper surface of the above-mentioned pressing portion (74) is positioned lower than the upper surface of the drawer (7), so that the height direction (Y direction) protrusion length of the pressing projection (75) based on the above-mentioned pressing portion (74) may be greater than the height direction (Y direction) protrusion length of the pressing projection (75) based on the upper surface of the drawer (7).

[0221] Accordingly, the height of the pressing projection (75) protruding from the pressing portion (74) is set relatively long so that interference with the stopper (55) and the aforementioned pressing elastic portion (46) is easy, and the height of the pressing projection (75) protruding from the drawer (7) is set relatively low so that a large space for the pressing projection (75) to move upwards of the drawer (7) does not need to be provided, so that the vertical shaking of the drawer (7) can be minimized. In addition, the distance between the upper surface of the drawer (7) and the maximum protrusion of the stopper (55) is minimized, and the stopper (55) can limit the vertical shaking of the drawer (7).

[0222] The height direction (Y direction) protrusion length of the pressure projection (75) based on the pressure portion (74) is set to be greater than the height direction (Y direction) protrusion length of the pressure projection (75) based on the upper surface of the drawer (7), so that the drawer (7) is drawn in and out, and the external force applied to the pressure projection (75) by the stopper (55) or the pressure elastic portion (46) is reduced, so that the rigidity of the pressure projection (75) is increased, and the reliability of the drawer (7) is improved by drawing in and out.

[0223] When the drawer (7) is withdrawn from the housing (4), the fixing portion (751) of the pressure projection (75) is increasingly interfered with by the contact surface (552) of the stopper (55) and receives a reaction force, so the user can know that the withdrawal of the drawer (7) is complete.

[0224] In order to separate the drawer (7) from the cabinet (1), the contact surface (552) applies a force greater than the reaction force that restricts the fixing portion (751) of the pressing projection (75) to pull the drawer (7) forward, and the steep slope (752) and the withdrawal portion (551) react to provide a force that withdraws the drawer (7) forward, so that the user can easily separate the drawer (7).

[0225] The above fixed portion (751) may include a first inclined portion (7511) extending from the maximum protrusion of the pressing projection (75) at a first incline and a second inclined portion (7512) extending from the end of the first inclined portion (7511) at an angle at least greater than the first incline.

[0226] The second inclined portion (7512) may be provided to sharply protrude upward in the height direction (Y direction) from the upper surface of the pressurizing portion (74). When the drawer (7) is withdrawn and inserted from the housing (4), a force pushing in the front-back direction (Z direction) is generated on the pressurizing projection (75), so that the resistance is maximized by the second inclined portion (7512), and the rigidity of the pressurizing projection (75) can be increased.

[0227] Figure 23 shows a state in which the drawer (7) is fully inserted into the housing (4) (a) and a state in which the drawer (7) is pulled out from the housing (4) by a set distance (b).

[0228] When the drawer (7) is fully inserted into the housing (4), the pressure elastic portion (46) can be placed at the rear of the rear wall (715) of the drawer (7). In addition, since the pressure portion (74) also protrudes toward the rear of the rear wall (715), interference between the pressure elastic portion (75) and the pressure projection (75) can occur at the rear of the storage portion (711, 712, 713) of the drawer (7). Therefore, the detergent storage capacity of the storage portion (711, 712, 713) can be maximized.

[0229] In addition, since the pressurizing portion (74) can be accommodated in the recessed portion (48) formed in the housing (4) to a size that accommodates the pressurizing portion (74), the size of the detergent supply device (D) can be increased without significantly increasing.

[0230] When the drawer (7) is fully inserted into the housing (4), the stopper (55) is provided so as not to be significantly spaced apart from the upper surface of the drawer (7), so that the drawer (7) can be prevented from moving up and down.

[0231] When the drawer (7) is fully inserted into the housing (4), the maximum protrusion of the pressure elastic portion (46) is positioned forward of the maximum protrusion of the pressure projection (75), thereby limiting the drawer (7) from being pulled out. Specifically, the rear inclined portion (462) can contact the fixed portion (751) and limit the movement of the pressure projection (75).

[0232] When the drawer (7) is pulled out from the housing (4) by a set distance, the maximum protrusion of the pressure projection (76) may be positioned further back than the maximum protrusion of the stopper (55). Accordingly, the forward movement of the drawer (7) may be restricted by interference between the maximum protrusions of each configuration.

[0233] In one embodiment of the present invention, when the drawer (7) is withdrawn from the housing (4) by a set distance, the fixing portion (751) of the pressure projection (75) receives a reaction force from the contact surface (552) of the stopper (55), so that the drawer (7) cannot be withdrawn by a set distance or more unless the user provides a force greater than the reaction force.

[0234] FIG. 24 illustrates an example in which the first region (71a) is set as the front space of the first storage unit, and the second region (71b) is set as the rear space of the first storage unit. Unlike that illustrated in FIG. 6, the first region (71a) may be set as either the left or right space of the first storage unit, and the second region (71b) may be set as the remaining space of the left and right spaces of the first storage unit.

[0235] The first supply port (772) and the second supply port (773) may be arranged to face each other with the discharge path (774) interposed therebetween. Furthermore, the first supply port (772) and the second supply port (773) may be positioned at points symmetrical with respect to the center of the discharge path (774).

[0236] The above discharge path (774) is a path that discharges the substance (water, detergent, or a mixture of water and detergent) inside the first storage unit (721) into the receiving space (43) when the water level inside the first storage unit (721) rises above the reference water level.

[0237] The above discharge path (774) may be provided to include a discharge pipe (774a) protruding from the bottom surface of the first storage unit (721) toward the cover body (771), and a flow-forming pipe (774b) extending from the cover body (771) toward the discharge pipe (774a) so as to accommodate the discharge pipe (774a). In this case, the free end of the flow-forming pipe (774b) may be installed to be spaced apart from the bottom surfaces of the second storage unit and the third storage unit (712, 713).

[0238] The above detergent first storage unit (71) may be provided to include a first storage unit (711) in which the first detergent is stored, a second detergent inlet (711a) provided on the upper surface of the first storage unit, and a second detergent discharge port (711b) that connects the second storage unit with the receiving space (43). The first detergent discharge port (711b) may be provided as a through hole penetrating the bottom surface or the rear surface of the first storage unit (711).

[0239] In order to prevent the body (71) of the drawer (7) from being easily separated from the housing (4) when the drawer (7) is withdrawn from the receiving space (43), the drawer (7) may be further provided with a holder (70a, 70b).

[0240] The above holder may be provided with a first holder (70a) and a second holder (70b) fixed to the body (71) so as to be spaced apart along the width direction (body width direction, X-axis direction) of the receiving space (43).

[0241] The first holder (70a) may be provided with a first pressing portion (74) protruding from the body (71) toward the rear surface (415) of the housing, and a first pressing projection (75) protruding from the first extension body toward the upper surface (411) of the housing. Similarly, the second holder (70b) may be provided with a second extension body (7511) protruding from the body (71) toward the rear surface (415) of the housing, and a second protruding body (7515) protruding from the second extension body toward the upper surface (411) of the housing.

[0242] As shown in Fig. 25, the detergent supply device (D) may further be provided with a holder interference part (91, 92) to prevent the drawer (7) from being easily separated from the housing (4) when it is withdrawn from the receiving space (43).

[0243] The above interference part may be provided to include a first interference part (91) that contacts a first holder (70a) provided in the drawer when the drawer (7) is withdrawn from the housing (4) by a preset reference distance, and a second interference part (92) that contacts a second holder (70b) provided in the drawer.

[0244] The first interference portion (91) may be provided to contact the side surface of the first holder (70a), and the second interference portion (92) may be provided to contact the side surface of the second holder (70b). To this end, the first interference portion (91) may be provided as a protrusion protruding from the first side surface (413) of the housing toward the second side surface (414), and the second interference portion (92) may be provided as a protrusion protruding from the second side surface (414) toward the first side surface (413).

[0245] When the above interference portions (91, 92) are provided to contact the side surfaces of the holders (751, 752), when the drawer (7) is pulled out from the housing (4) by the reference distance, the possibility of the body (71) of the drawer being separated from the receiving space (43) can be reduced, and the position of the body (71) can be stably fixed.

[0246] The above first interference portion (91) may be provided to include a first interference portion first slope (911) and a first interference portion second slope (912).

[0247] The first inclined surface (911) of the first interference portion may be provided as a surface that protrudes from one side (first side, 413) of the receiving space (43) toward one side (the other side of the receiving space) of the drawer (7) as it faces the withdrawal direction of the drawer (7) from the rear surface of the receiving space (43).

[0248] The second inclined surface (912) of the first interference portion may be provided as a surface that protrudes from one side (first side, 413) of the receiving space (43) toward one side (other side of the receiving space, 414) of the drawer as it faces the insertion direction of the drawer, but is connected to the first inclined surface (911) of the first interference portion.

[0249] The above second interference portion (92) may be provided to include a second interference portion first slope (921) and a second interference portion second slope (922).

[0250] The first inclined surface (921) of the second interference portion may be provided as a surface that protrudes from the other side (second side, 414) of the receiving space (43) toward the other side (one side of the receiving space, 413) of the drawer (7) as it faces the withdrawal direction of the drawer (7) from the rear surface of the receiving space (43). The second inclined surface (922) of the second interference portion may be provided as a surface that protrudes from the other side (second side, 414) of the receiving space (43) toward the other side (one side of the receiving space, 413) of the drawer as it faces the insertion direction of the drawer, but is connected to the first inclined surface (921) of the second interference portion.

[0251] If at least one of the first interference portion (91) and the second interference portion (92) is provided with a structure having two inclined surfaces, frictional force will gradually act on the drawer (7) when the drawer (7) is withdrawn from the receiving space (43), so that a smooth operating feeling of the drawer (7) can be provided to the user.

[0252] Unlike the above, the first interference portion (91) and the second interference portion (92) may be provided in the euro forming portion (5).

[0253] To this end, the euro-forming part (5) may be provided in the euro body (54) to include a first support plate (93) positioned between one side of the housing (first side, 413) and one side of the drawer, and a second support plate (94) positioned between the other side of the housing (second side, 414) and the other side of the drawer.

[0254] In this case, the first interference portion (91) may be provided on the first support plate (93), and the second interference portion (92) may be provided on the second support plate (94).

[0255] The first interference portion (91) may be provided to include a first inclined surface (911) of the first interference portion and a second inclined surface (912) of the first interference portion fixed to the first support plate (93), and the second interference portion (92) may be provided to include a first inclined surface (921) of the second interference portion and a second inclined surface (922) of the second interference portion fixed to the second support plate (94). Since the detergent supply device and the clothes treatment device described above are merely preferred embodiments, the scope of the rights of the present application is not limited to the above-described embodiments.
