[0152] Fig. 9 is a cross-sectional view taken along line A-A' of Fig. 8 according to various embodiments. Fig. 10 is a cross-sectional view taken along line B-B' of Fig. 8 according to various embodiments.

[0153] Referring to FIG. 9, a garment treatment device (1) according to one embodiment can supply detergent stored in a first detergent box (121) to a tub (20).

[0154] For example, water discharged from the drainage device (70) can be guided to the detergent supply device (100) by the circulation guide (101). The water guided by the circulation guide (101) can flow into the interior of the detergent supply device (100) through the inlet port (111). The water flowing in through the inlet port (111) can pass through the first connection portion (117) of the case guide (116).

[0155] The first detergent pump (131) may be arranged to directly supply detergent to the case guide (116). The first detergent discharge port (131b) of the first detergent pump (131) may be connected to the detergent case (110) to directly supply detergent to the case guide (116) through which water flowing into the detergent supply device (100) flows. The first detergent discharge port (131b) may be connected to the first connection port (117a) of the first connection port (117). The detergent discharged through the first detergent discharge port (131b) may be directly discharged to the case guide (116) through the first connection port (117a).

[0156] Since the first detergent pump (131) is configured to directly supply detergent to the case guide (116) through which water flows through the detergent supply device (100), the garment treatment device (1) according to one embodiment can minimize and / or reduce the detergent from accumulating and coagulating in the detergent supply device (100). The garment treatment device (1) according to one embodiment can minimize and / or reduce the path through which the detergent is supplied by the first detergent pump (131). The garment treatment device (1) according to one embodiment has minimized / reduced the section in which the detergent moves between the first detergent discharge portion (131b) through which the detergent is discharged from the first detergent pump (131) and the first connection port (117a), and thus can reduce the possibility of the detergent from accumulating and coagulating.

[0157] According to one embodiment, the clothing treatment device (1) can prevent / reduce detergent from coagulating around the first detergent discharge port (131b) of the first detergent pump (131), since water passing through the detergent supply device (100) always passes around the first detergent discharge port (131b) of the first detergent pump (131). According to one embodiment, the clothing treatment device (1) can prevent / reduce detergent from coagulating around the first detergent discharge port (131b) of the first detergent pump (131), so that water passing through the case guide (116) can be mixed with detergent existing between the first detergent discharge port (131b) and the first connection port (117a) and be discharged together from the detergent supply device (100). That is, the water passing through the case guide (116) can remove detergent existing between the first detergent discharge port (131b) and the first connection port (117a) from the area between the first detergent discharge port (131b) and the first connection port (117a).

[0158] Water and detergent passing through the first connection (117) can flow to the second connection (118) through the extension (119) of the case guide (116). When the detergent stored in the first detergent container (121) is supplied to the tub (20), the second detergent pump (132) may not operate. The second detergent pump (132) may not additionally supply detergent to the second connection (118). The water and detergent passing through the second connection (118) are discharged to the detergent guide (102) through the discharge port (112) and can be provided to the tub (20) along the detergent guide (102).

[0159] Referring to FIG. 10, a clothing treatment device (1) according to one embodiment can supply detergent stored in a second detergent box (122) or a third detergent box (123) to a tub (20).

[0160] For example, water discharged from the drainage device (70) can be guided to the detergent supply device (100) by the circulation guide (101). The water guided by the circulation guide (101) can flow into the interior of the detergent supply device (100) through the inlet port (111). The water flowing in through the inlet port (111) can pass through the first connection portion (117) of the case guide (116).

[0161] When the detergent stored in the second detergent compartment (122) or the third detergent compartment (123) is supplied to the tub (20), the first detergent pump (131) may not operate. The first detergent pump (131) may not supply detergent to the first connection portion (117). Water passing through the first connection portion (117) may flow to the second connection portion (118) through the extension portion (119) of the case guide (116).

[0162] The second detergent pump (132) may be arranged to directly supply detergent to the case guide (116). The second detergent discharge port (132c) of the second detergent pump (132) may be connected to the detergent case (110) to directly supply detergent to the case guide (116) through which water flowing into the detergent supply device (100) flows. The second detergent discharge port (132c) may be connected to the second connection port (118a) of the second connection port (118). The detergent discharged through the second detergent discharge port (132c) may be directly discharged to the case guide (116) through the second connection port (118a).

[0163] Since the second detergent pump (132) is configured to directly supply detergent to the case guide (116) through which water flows through the detergent supply device (100), the garment treatment device (1) according to one embodiment can minimize and / or reduce the detergent from accumulating and coagulating in the detergent supply device (100). The garment treatment device (1) according to one embodiment can minimize and / or reduce the path through which the detergent is supplied by the second detergent pump (132). The garment treatment device (1) according to one embodiment has minimized and / or reduced the section through which the detergent moves between the second detergent discharge portion (132c) through which the detergent is discharged from the second detergent pump (132) and the second connection port (118a), and thus can reduce the possibility of the detergent from accumulating and coagulating.

[0164] According to one embodiment, the clothing treatment device (1) can prevent and / or reduce the detergent from coagulating around the second detergent discharge port (132c) of the second detergent pump (132) because the water passing through the detergent supply device (100) always passes around the second detergent discharge port (132c) of the second detergent pump (132). According to one embodiment, the clothing treatment device (1) can allow the water passing through the case guide (116) to be mixed with the detergent existing between the second detergent discharge port (132c) and the second connection port (118a) and be discharged together from the detergent supply device (100). That is, the water passing through the case guide (116) can remove the detergent existing between the second detergent discharge port (132c) and the second connection port (118a) from the area between the second detergent discharge port (132c) and the second connection port (118a).

[0165] For example, when it is desired to supply both the detergent stored in the first detergent compartment (121) and the detergent stored in the second detergent compartment (122) and / or the third detergent compartment (123), both the first detergent pump (131) and the second detergent pump (132) may operate. While the first detergent pump (131) supplies detergent to the first connection portion (117) and the second detergent pump (132) supplies detergent to the second connection portion (118), water flowing into the detergent supply device (100) may sequentially pass through the case guide (116) and be mixed with a plurality of detergents.

[0166] Fig. 11 is a flowchart showing an example of a control method of a garment treatment device according to various embodiments.

[0167] Referring to FIG. 11, a user can select a detergent to be added during a washing cycle via at least one input interface (16) of the garment treatment device (1) (1100). For example, according to one embodiment, the garment treatment device (1) may store a general detergent in a first detergent compartment (121), a fabric softener in a second detergent compartment (122), and a neutral detergent in a third detergent compartment (123).

[0168] When a general detergent is selected as the detergent to be injected during the washing cycle, the control unit (90) according to one embodiment can operate the first detergent pump (131) (1200). As the first detergent pump (131) operates, the general detergent stored in the first detergent compartment (121) can be supplied to the case guide (116) of the detergent supply device (100). The general detergent stored in the first detergent compartment (121) by the first detergent pump (131) can be discharged to the first connection portion (117) of the case guide (116).

[0169] The control unit (90) can operate the circulation pump (76) to supply water to the detergent supply device (100) (1300). As the circulation pump (76) operates, water in the tub (20) can pass through the drainage device (70) and be supplied to the detergent supply device (100). The water supplied to the detergent supply device (100) can pass through the case guide (116) and be mixed with the general detergent supplied to the case guide (116) by the first detergent pump (131) and be discharged from the detergent supply device (100). The water flowing into the detergent supply device (100) can pass through the first connection portion (117) of the case guide (116) and be mixed with the general detergent. The water and the general detergent discharged from the detergent supply device (100) can be guided to the tub (20) through the detergent guide (102).

[0170] When a neutral detergent is selected as the detergent to be injected during the washing cycle, the control unit (90) according to one embodiment can operate the second detergent pump (132) (1201). As the second detergent pump (132) operates, the neutral detergent stored in the third detergent compartment (123) can be supplied to the case guide (116) of the detergent supply device (100). The neutral detergent stored in the third detergent compartment (123) by the second detergent pump (132) can be discharged to the second connection portion (118) of the case guide (116).
