Description

Detergent supply device and clothes treatment device

[0001] The present application relates to a detergent supply device and a clothing treatment device equipped with the detergent supply device.

[0002] A clothing treatment device that separates waste from laundry objects (clothes, etc.) using water is provided to include a tub in which water is stored, a drum rotatably provided inside the tub in which clothes are stored, a tub water supply unit that supplies water to the tub, and a tub drain unit that drains water stored in the tub.

[0003] For easy separation of waste, some conventional clothing treatment devices have been equipped with a detergent supply device that supplies detergent to the tub. Some conventional detergent supply devices include a drawer that is removable from the cabinet of the clothing treatment device, and a detergent channel provided in the drawer that guides detergent to the tub.

[0004] The above-described conventional detergent supply device is equipped with the tub water supply unit to supply water to the detergent channel, so that when the tub water supply unit is operated, the detergent injected into the detergent channel is supplied to the tub together with water (Publication No. 10-2020-0007549).

[0005] Some conventional detergent supply devices have a detergent chamber and a discharge path for supplying liquid detergent to a tub. Devices capable of supplying liquid detergent to a tub have a siphon path in the detergent chamber, allowing detergent and water to move from the detergent chamber to the tub when the water level inside the detergent chamber rises above the siphon-inducing level. However, conventional detergent supply devices with the aforementioned structure can have problems in that they cannot move the detergent to the tub when the viscosity of the liquid detergent is high.

[0006] Meanwhile, some conventional detergent supply devices were equipped with a first water inlet connecting a cold water source and a detergent chamber, and a second water inlet connecting a hot water source and a detergent chamber. If only one of the cold water source and the hot water supply pipe was present in the installation space of the garment treatment device, the remaining water inlet was not connected to the water source and was installed blocked with a stopper or the like. Detergent supply devices installed as described above could experience a phenomenon in which water leaked from the water inlet that was not connected to the water source when water was supplied to the detergent supply device.

[0007] The present invention aims to solve the problem of providing a detergent supply device and a clothing treatment device capable of easily discharging a high viscosity liquid detergent.

[0098] The above-mentioned flow path (5) may be provided to include a flow path (54) that is fixed inside the receiving space (41) and positioned on the upper portion of the body (71), a supply flow path (541, 542) provided in the flow path (544) to provide a water movement path, and a guide flow path (51, 52). The flow path (54) may be fixed to the upper surface (411) of the housing, and the flow paths may be provided to be positioned between the upper surface (411) and the flow path (54).

[0099] The above supply path may include a first supply path (541) and a second supply path (542) that provide a path for water supplied from the water inlets (417, 418, 419).

[0100] The first supply path (541) may be provided as a path that guides water supplied from the first water supply port (417) and the second water supply port (418) in the width direction of the receiving space (41) (X-axis direction, direction perpendicular to the direction in which the drawer is withdrawn, width direction of the drawer), and the second supply path (542) may be provided as a path that guides water supplied from the third water supply port (419) in the depth direction of the receiving space (41) (Z-axis direction, direction in which the drawer is withdrawn).

[0101] The first supply flow path (541) may be provided as a groove in which the rear edge of the euro body (54) is concavely bent toward the lower surface (412, the bottom surface of the receiving space) of the receiving space. The second supply flow path (542) may be provided as a groove in which the euro body (54) is concavely bent toward the lower surface (412). The first supply flow path (541) and the second supply flow path (542) form flow paths (independent flow paths) separated from each other by a flow partition (546).

[0102] The first supply path (541) and guide paths (51, 52) may be provided as paths for supplying water to the second detergent storage unit (73) and one of the two first detergent storage units (72), and the second supply path (542) may be provided as a path for supplying water to the other of the two first detergent storage units (72).

[0103] The second supply path (542) may be provided with a first discharge hole (544, second supply path first discharge hole) for discharging water to the first supply port (726) of the first detergent storage unit, and a second discharge hole (545, second supply path second discharge hole) for supplying water to the second supply port (727) of the first detergent storage unit.

[0104] The above guide path may be provided to include a first guide path (51) that supplies water from the first supply path (541) to the first detergent storage unit (72), and a second guide path (52) that supplies water from the first supply path (541) to the second detergent storage unit (73).

[0105] The first guide passage (51) may be provided with a first discharge hole (511, first supply passage first discharge hole) for discharging water to the first supply port (726) of the first detergent storage unit, and a second discharge hole (512, first supply passage second discharge hole) for supplying water to the second supply port (727) of the first detergent storage unit.

[0106] The second guide channel (52) may be provided to include a connecting channel (52a) extending from the first supply channel (541) toward the second detergent inlet (732), and a diffusion channel (52b) extending from the connecting channel (52a) and having a shape that surrounds the edge of the second detergent inlet (732).

[0107] As illustrated in Fig. 8, the connecting channel (52a) may be formed by a first forming wall (521) extending from the first supply channel (541) toward the second detergent inlet (732), and a second forming wall (522) extending from the first supply channel (541) toward the second detergent inlet and positioned at a point spaced apart from the first forming wall. The connecting channel (52a) may be provided with a connecting channel discharge hole (523) for discharging water to the second detergent inlet (732).

[0108] In order to minimize water remaining inside the connecting passage (52a), the bottom surface of the connecting passage (52a) may be provided with a downward sloping surface toward the second detergent inlet (732).

[0109] The above diffusion path (52b) may be provided to guide water from the outlet of the connecting path (52a) to the space between the first forming wall (521) and the edge of the second detergent inlet (732), and to the space between the second forming wall (522) and the edge of the second detergent inlet (732).

[0110] The above diffusion channel (52b) may include a first surface (524) that is formed in a shape that surrounds the first forming wall (521) and the second forming wall (522) and is positioned above the second detergent inlet (732), and a second surface (526) that is formed along the edge of the first surface (524) and is positioned above the second detergent inlet (732). A first diffusion channel discharge hole (525) may be formed on the first surface (524), and a second diffusion channel discharge hole (527) may be formed on the second surface (526).

[0111] In order to minimize water remaining inside the diffusion channel (52b), the second surface (526) may be provided as a downwardly inclined surface toward the edge of the first surface (524). The first surface (524) may be provided as a horizontal surface, or may be provided as a downwardly inclined surface toward the connecting channel (523).

[0112] The second guide channel (52) of the above-described structure not only supplies water to the center of the second detergent chamber (731) through the connecting channel (52a), but also supplies water from the edge of the second detergent chamber (731) to the center of the second detergent chamber (731) through the diffusion channel (52b), so that the problem of detergent remaining inside the second detergent chamber (731) can be minimized.

[0113] Meanwhile, if the pressure of the water supplied to the first water supply port (417) or the second water supply port (418) is high, the water discharged from the connecting passage (52a) may not be supplied to the entire area of ​​the diffusion passage (52b) and may be concentrated in the area located on the right side of Fig. 8. This phenomenon increases the possibility of detergent remaining in the second detergent chamber (731).

[0114] To minimize the above-described problem, at least one of the first forming wall (521) and the second forming wall (522) may be provided to supply water inside the connecting passage (52a) to the diffusion passage (52b) in an overflow manner.

[0115] That is, at least one of the gap between the upper end of the first forming wall (521) and the upper surface (411) of the receiving space and the gap between the upper end of the second forming wall (522) and the upper surface (411) of the receiving space may be provided to increase toward the second detergent inlet (732).

[0116] This means that at least one of the upper end of the first forming wall (521) and the upper end of the second forming wall (522) can be provided to be inclined downward as it faces the second detergent inlet (732), and FIG. 7 illustrates an example in which the upper ends of both forming walls (521, 522) are provided to be inclined.

[0117] When the upper ends of the above-mentioned forming walls (521, 522) are provided in an inclined shape, a space is formed between the upper ends of the forming walls (521, 522) and the upper surface (411) of the receiving space, so that some of the water moving from the inlet of the connecting passage (52a) toward the outlet can move beyond the forming walls to the diffusion passage (52b). Accordingly, the phenomenon of water concentrating in a portion of the diffusion passage (52b) can be minimized.

[0118] Although not shown in the drawing, the second guide channel (52) may be provided with a communication hole for discharging water within the connecting channel (52a) to the diffusion channel (52b). The communication hole may be provided with a plurality of holes penetrating the first forming wall (521) and a plurality of holes penetrating the second forming wall (522).

[0119] In order to facilitate the flow of water inside the first supply channel (541) into the guide channel (51, 52), a supply guide (544, 545) may be further provided in the channel section (5).

[0120] The above supply guide may be provided to include a first guide (544) protruding from the inlet of the first guide channel (51) toward the edge of the first supply channel (541), and a second guide (545) protruding from the inlet of the second guide channel (52) toward the edge of the first supply channel (541).

[0121] The detergent supply device (D) of the above-described structure can minimize detergent residue in the drawer (7), but it is difficult to minimize detergent residue inside the receiving space (41).

[0122] In order to minimize detergent residue within the receiving space (41), the flow path (5) may further be provided with a washing hole (543). As illustrated in FIG. 9, the washing hole (543) may be provided as a means for discharging water into the space between the rear surface (415) of the receiving space 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 receiving space).

[0123] When water is supplied to the first supply path (541) through the first water supply port (417) and the second water supply port (418), some of the water in the first supply path (541) will be supplied to the first detergent storage unit (72) through the first guide path (51), and the remainder will be supplied to the second detergent storage unit (73) through the second guide path (52).

[0124] The water inside the first guide passage (51) moves to the first supply port (726) of the first detergent storage unit through the first discharge hole (511) and moves to the second supply port (727) of the first detergent storage unit through the second discharge hole (512). That is, the detergent supply device (D) described above supplies water to the front and rear areas of the discharge passage (723) simultaneously (supplies water to the left and right areas of the discharge passage simultaneously).

[0125] Since the first discharge hole (511) is located in the first region (721a) and the second discharge hole (512) is located in the second region (721b), the detergent supply device (D) described above can reduce the concentration of the detergent stored in the first detergent chamber (721) in a short period of time. Accordingly, the detergent supply device (D) described above can reduce the phenomenon in which detergent and water cannot escape through the discharge path (723) even if a detergent with high viscosity is injected into the first detergent chamber (721).

[0126] As illustrated in the drawing, the discharge path (723) may be provided with a spacer (723c). The spacer (723c) may be provided as a means for maintaining a gap between the lower end of the flow path-forming pipe (723b) and the bottom surface of the first detergent chamber (721), and a gap between the inner surface of the flow path-forming pipe (723b) and the outer surface of the discharge pipe (723a). In the case of the discharge path provided with the spacer (723c), the flow path-forming pipe (723b) does not need to be fixed to the cover body (725).

[0127] Meanwhile, when water is supplied to the second supply channel (542) through the third water supply port (419), the water inside the second supply channel (542) will be supplied to the first supply port and the second supply port of the first detergent storage unit through the first discharge hole (544) of the second supply channel and the second discharge hole (545) of the second supply channel.

[0128] In the detergent supply device (D) described above, if water is supplied to the first supply path (541) while only one of the first water supply port (417) and the second water supply port (418) is connected to the water source, water leakage may occur through the water supply port that is not connected to the water source.

[0129] If only one of the first water supply port (417) and the second water supply port (418) is connected to a water source, the other water supply port may be closed with a plug or the like. However, if the pressure inside the first supply path (541) is high, water leakage may occur through the water supply port that is not connected to the water source despite the presence of the plug.

[0130] In order to prevent the above-described phenomenon, the detergent supply device (D) may further be equipped with a backflow prevention unit (55), and Fig. 10 illustrates an example of the backflow prevention unit (55).

[0131] As illustrated in Fig. 10, the backflow prevention unit (55) is provided in the first supply path (541) and is positioned between the first water supply port (417) and the second water supply port (418), and may be provided as a wall that restricts water discharged from one water supply port from moving in the direction in which the other water supply port is located.

[0132] The above-mentioned backflow prevention unit (55) may be provided only with a blocking wall (551) fixed to the first supply path (541) and positioned between the first water supply port (417) and the second water supply port (418), or may be provided with the blocking wall (551) and an extension wall (552) extending from the blocking wall (551).

[0133] The above blocking wall (551) may be provided with a slope that is inclined toward the center of the first supply channel (541) as it faces the direction in which the guide channels (51, 52) are located. This is to minimize a decrease in the flow rate of water flowing in through the second water supply port (418).

[0134] The above extension wall (552) may be provided as a wall extending from the free end of the blocking wall (551) toward the direction in which the guide channels (51, 52) are positioned. In this case, the extension wall (552) may be provided parallel to the width direction of the receiving space (41) (the direction in which water flows along the first supply channel). This is to minimize a decrease in the flow rate of water moving along the first supply channel.

[0135] When the backflow prevention unit (55) is provided in the flow path section (5), the water supplied from the first water supply port (417) has difficulty moving in the direction in which the second water supply port (418) is located due to the backflow prevention unit (55). This is because the flow resistance in the direction in which the guide channels (51, 52) are located is smaller, so most of the water will flow in the direction in which the guide channels are located. Therefore, the backflow prevention unit (55) can reduce the possibility of water leakage through the second water supply port (418) when only the first water supply port (417) is connected to the water source.

[0136] Meanwhile, even if only the second water supply port (418) is connected to the water source, the amount of water supplied from the second water supply port (418) moving in the direction in which the guide paths (51, 52) are located along the backflow prevention unit (55) (the amount of water moving in the forward direction) will be greater than the amount moving in the direction in which the first water supply port (417) is located (the amount of water moving in the reverse direction). Therefore, the backflow prevention unit (55) can also reduce the possibility of water leakage through the first water supply port (417) when only the second water supply port (418) is connected to the water source.

[0137] As shown in Fig. 11, the detergent supply device (D) may further be provided with a holder stopper (91, 92) to prevent the drawer (7) from being easily separated from the housing (4) when it is withdrawn from the receiving space (41).

[0138] The above stopper may be provided to include a first stopper (91) that contacts a first holder (751) provided in the drawer when the drawer (7) is withdrawn from the housing (4) by a preset reference distance, and a second stopper (92) that contacts a second holder (752) provided in the drawer.

[0139] The first stopper (91) may be provided to contact the side surface of the first holder (751), and the second stopper (92) may be provided to contact the side surface of the second holder (752). To this end, the first stopper (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 stopper (92) may be provided as a protrusion protruding from the second side surface (414) toward the first side surface (413).

[0140] When the stopper (91, 92) is provided to contact the side of the holder (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 (41) can be reduced, and the position of the body (71) can be stably fixed.

[0141] The above first stopper (91) may be provided to include a first stopper first inclined surface (911) and a first stopper second inclined surface (912).

[0142] The first slope surface (911) of the first stopper may be provided as a surface that protrudes from one side (first side, 413) of the receiving space (41) 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 (41).

[0143] The second inclined surface (912) of the first stopper may be provided as a surface that protrudes from one side (first side, 413) of the receiving space (41) toward one side (other side of the receiving space, 414) of the drawer toward the insertion direction of the drawer, but is connected to the first inclined surface (911) of the first stopper.

[0144] The above second stopper (92) may be provided to include a second stopper first inclined surface (921) and a second stopper second inclined surface (922).

[0145] The first inclined surface (921) of the second stopper may be provided as a surface that protrudes from the other side (second side, 414) of the receiving space (41) 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 (41). The second inclined surface (922) of the second stopper may be provided as a surface that protrudes from the other side (second side, 414) of the receiving space (41) 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 stopper.

[0146] If at least one of the first stopper (91) and the second stopper (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 (41), so that a smooth operating feeling of the drawer (7) can be provided to the user.

[0147] Unlike the above, the first stopper (91) and the second stopper (92) may be provided in the euro section (5).

[0148] To this end, the euro portion (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.

[0149] In this case, the first stopper (91) may be provided on the first support plate (93), and the second stopper (92) may be provided on the second support plate (94).

[0150] The first stopper (91) may be provided to include a first stopper first inclined surface (911) and a first stopper second inclined surface (912) fixed to the first support plate (93), and the second stopper (92) may be provided to include a second stopper first inclined surface (921) and a second stopper second inclined surface (922) fixed to the second support plate (94).

[0151] 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.
