[0101] The refrigerant expanded through the expansion valve can absorb heat in the evaporator (93) and cool the surrounding air. That is, the evaporator (93) can cool the high-temperature, humid air that has passed through the inside of the drum (30) and remove moisture. The air from which moisture has been removed passes through the condenser (92) and can be heated again while exchanging heat with the refrigerant passing through the condenser (92). That is, the condenser (92) can heat the air that has passed through the evaporator (93). The condenser (92) and the evaporator (93) can be referred to as a heat exchanger.

[0102] For example, the drying device (80) may further include a drying heater (99). The drying heater (99) may increase the drying efficiency of the drying device (80). For example, the drying device (80) may also replace heat pump components with the drying heater (99).

[0103] The drying heater (99) can heat the air flowing into the interior of the drying device (80). The drying heater (99) can be placed in the heating path (86). The drying heater (99) can be placed downstream from the condenser (92) along the flow of air passing through the drying device (80).

The second water supply pipe (43b) may be provided so as to prevent the pipe from being inclined upward from the pressure reducing device (101) to the water supply port (140). The second water supply pipe (43b) may be provided so as to slope in the direction of gravity without a portion that slopes in the opposite direction to the direction of gravity from the pressure reducing device (101) to the water supply port (140). The second water supply pipe (43b) may include a portion that extends horizontally without being inclined.

[0169] According to this configuration, the clothing treatment device (1) according to various embodiments can prevent residual water from remaining inside the water supply pipe (43) when the water supply through the water supply valve (41) is stopped.

[0170] Fig. 13 illustrates the interior of a tub duct according to one embodiment of the present disclosure. Fig. 14 is an enlarged view of portion D shown in Fig. 2.

[0171] Referring to FIGS. 13 and 14, the tub (20) of the garment treatment device (1) according to various embodiments may include a step portion (28c) formed to change the cross-sectional area of ​​the exhaust passage (P). The step portion (28c) may be provided in the tub duct (28). The step portion (28c) may be provided to correspond to the outer circumferential surface of the tub (20).

[0172] The size of the exhaust passage (P) can be changed along the direction of air flow. The cross-sectional area perpendicular to the direction of air flow in the exhaust passage (P) can be changed as the air flows along the exhaust passage (P). The step portion (28c) can be formed so that the cross-sectional area approximately perpendicular to the direction of air flow increases as the air flows in the exhaust passage (P). For example, the step portion (28c) can be formed so that the cross-sectional area of ​​a portion of the exhaust passage (P) formed by the duct connection portion (28b) is larger than the cross-sectional area of ​​a portion of the exhaust passage (P) formed by the recess portion (28a). The step portion (28c) can be formed so that the width (w2) of a portion of the exhaust passage (P) formed by the duct connection portion (28b) is larger than the width (w1) of a portion of the exhaust passage (P) formed by the recess portion (28a).

[0174] While the air discharged from the inside of the tub (20) flows through the exhaust path (P), the air may collide with the stepped portion (28c), and thus, foreign substances such as lint moving with the air may be separated from the air and accumulate in the stepped portion (28c) of the tub duct (28). A relatively large amount of foreign substances may accumulate in the stepped portion (28c) of the tub duct (28).

[0175] The water supply port (140) may be provided to face the step portion (28c). For example, the outlet (143) of the water supply port (140) may be provided to face the step portion (28c). The water supply port (140) may be provided to discharge water to a portion of the exhaust path (P) where the step portion (28c) is located.

[0176] In a garment treatment device (1) according to one embodiment of the present disclosure, since the water supply port (140) discharges water supplied by the water supply device (40) toward the stepped portion (28c) of the tub duct (28), foreign substances accumulated in the stepped portion (28c) can be cleaned, and thus, the exhaust passage (P) can be easily managed. Water flowing into the exhaust passage (P) through the water supply port (140) collides with the tub duct (28) and the duct cover (29), and after cleaning foreign substances adhering to the tub duct (28) and the duct cover (29), can flow into the interior of the tub (20) through the air outlet (27).
