The drum (30) is rotated within the tub (20) by the rotary force transmitted through the rotary shaft (41).
[0105] A driving motor (42) may be provided on the outside of the tub (20). The driving motor (42) may be connected to the drum (30) via a rotating shaft (41). The rotating shaft (41) passes through the tub back (200) of the tub (20) and is rotatably supported by a bearing (52) and a bearing housing (51).
[0106] The driving motor (42) may include a stator fixed to the outside of the tub back (200) and a rotor that is rotatably provided and connected to a rotating shaft (41). The stator can electromagnetically interact with the rotor to convert rotational electrical power into mechanical rotational power.

[0107] The drum back (34) can be connected to a rotary shaft (41) via a flange shaft (60). The flange shaft (60) can be provided to transmit power from a driving motor (42).
[0108] The flange shaft (60) may include a hub portion (61) positioned at the center of the drum back (34) and a plurality of flange portions (62) extending radially from the hub portion (61). A shaft coupling portion (63) for installing a rotating shaft (41) may be formed at the center of the hub portion (61).
[0109] A plurality of flange portions (62) may be formed at approximately 120-degree intervals centered on the hub portion (61). The plurality of flange portions (62) may be formed to correspond to the diameter of the drum bag (34). A plurality of fastening holes (64) may be formed at one end of each flange portion (62). The plurality of fastening holes (64) may be formed to correspond to the coupling holes (35) of the drum (30). In the embodiment of the present invention, two fastening holes are formed in one flange portion, but the spirit of the present invention is not limited thereto. For example, the fastening holes may be provided in various numbers and arrangements depending on the size and shape of the drum and the flange portion.
[0110] A rotary shaft (41) is arranged between the drum (30) and the driving motor (42). One end of the rotary shaft (41) is connected to the drum back (34), and the other end of the rotary shaft (41) extends to the outside of the tub back (200). When the driving motor (42) rotates the rotary shaft (41), the drum (30) connected to the rotary shaft (41) rotates around the rotary shaft (41).
[0111] The tub back (200) may be provided with a bearing housing (51) that rotatably supports the rotating shaft (41). The bearing housing (51) may be provided with an aluminum alloy. For example, the bearing housing (51) may be formed with aluminum die casting (ALDC). However, the present invention is not limited thereto, and the bearing housing (51) may also be formed with stainless steel. It is sufficient that the bearing housing (51) is formed with a material having a higher strength than the material forming the tub (20).
[0112] The bearing housing (51) can be coupled to the tub (20). Specifically, the bearing housing (51) can be coupled to the tub back (200). The bearing housing (51) can be inserted into the tub back (200) when the tub (20) is injection-molded. More specifically, the tub (20) can be formed by inserting the bearing housing (51) into a mold (not shown) for forming the tub (20) and then injecting molten resin into the mold. Through this, the tub (20) with the bearing housing (51) inserted into the inside of the tub back (200) can be integrally formed.
[0113] Bearings (52) can be installed between the bearing housing (51) and the rotary shaft (41) so that the rotary shaft (41) can rotate smoothly.
[0114] The clothing treatment device (1) may include a drying device (70) for drying laundry accommodated inside the drum (30). The drying device (70) may be provided to heat air and supply it to the inside of the tub (20). The drying device (70) may be configured to dry and heat air discharged from the tub (20) and circulate the dried and heated air into the inside of the tub (20) to dry clothing inside the drum (30). The drying device (70) according to various embodiments may be arranged on the upper portion of the tub (20).
[0115] The drying device (70) may include a drying case (70a) in which a heat pump may be installed.

The drying cover (70c) may cover the open upper surface of the drying base (70b).
[0116] A drying device (70) according to various embodiments may be configured as a heat pump. The drying device (70) may include a compressor (71), a condenser (72), an evaporator (73), an expansion valve, and a refrigerant pipe (75) through which refrigerant circulates and exchanges heat. The compressor (71), condenser (72), evaporator (73), etc., which constitute the heat pump, may be placed in a drying case (70a). For example, the drying device (70) may be mounted on a clothing treatment device (1) as a single module.
[0117] The compressor (71) compresses the refrigerant, and the compressed high-temperature, high-pressure refrigerant is transferred to the condenser (72). The condenser (72) can cool the refrigerant and heat the surrounding air. The heated air can be introduced into the drum (30) to dry the laundry.
[0118] The refrigerant expanded through the expansion valve can absorb heat in the evaporator (73) and cool the surrounding air. That is, the evaporator (73) 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 (72) and can be reheated while exchanging heat with the refrigerant in the condenser (72). That is, the condenser (72) can heat the air that has passed through the evaporator (73). The condenser (72) and the evaporator (73) can be referred to as a heat exchanger.
[0119] Additionally, the drying device (70) may further include a heater (80) in addition to the heat pump to increase drying efficiency. Without being limited thereto, the drying device (70) may include only the heat pump or only the heater (80).
[0120] A heater (80) can heat air introduced into a drying device (70). The heater (80) can be placed in a heating path (77). The heater (80) can be placed downstream of a condenser (72). In addition, the heater (80) can be provided in a small size so as to minimize path resistance. For example, the heater (80) can be a sheath heater.
[0121] The drying device (70) may be provided with an inlet passage (76) through which air discharged from the tub (20) is introduced. The drying device (70) may be provided with a heating passage (77) through which air introduced into the drying device (70) through the inlet passage (76) is heat-exchanged. The drying device (70) may be provided with a supply passage (78) through which air that has passed through the heating passage (77) and has undergone heat exchange is supplied to the tub (20).
[0122] The inlet passage (76) is provided so that air passing through the inside of the tub (20) can be introduced into the drying device (70). The inlet passage (76) may be located on the upper side of the tub (20). The inlet passage (76) may be connected to an exhaust passage (P) formed at the rear of the tub (20).
[0123] The drying device (70) may include an inlet guide (76a) connected to the tub (20). The inlet guide (76a) may guide air discharged from the tub (20) to an inlet passage (76). The inlet passage (76) may be communicated with an exhaust passage (P) formed in the tub (20) through the inlet guide (76a). Air passing through the exhaust passage (P) may be introduced into the inlet passage (76) of the drying device (70) through the inlet guide (76a).
[0124] A filter (81) may be provided in the inlet passage (76) to filter out foreign substances such as lint contained in the air flowing in through the exhaust passage (P) from the tub (20). The air flowing in through the inlet passage (76) may flow to the heating passage (77) through the filter (81).
[0125] A condenser (72) and an evaporator (73) may be placed in the heating passage (77). The introduced air may be hot and humid as it has passed through the inside of the tub (20). The hot and humid air may be cooled in the evaporator (73) placed in the heating passage (77) to remove moisture. Thereafter, the air may be reheated by passing through the condenser (72).
[0126] The supply path (78) can supply heated air back into the tub (20) by passing through the condenser (72). The supply path (78) is connected to the heating path (77) and can extend downward to discharge heated air toward the opening of the tub (20).
[0127] The drying device (70) may include a blower fan (78a) for causing air to flow into the interior of the tub (20). In one embodiment, the blower fan (78a) may be disposed in the supply passage (78). The blower fan (78a) may cause air from the heating passage (77) and the supply passage (78) to flow into the interior of the drum (30). For example, the blower fan (78a) may include a sirocco fan.
[0128] The supply path (78) may extend approximately vertically from the front end of the drying base (70b) toward the tub (20). The front end of the drying base (70b) may refer to an area adjacent to the front end of the drying base (70b). The supply path (78) may extend downward from the front end of the drying base (70b) located above the tub (20) toward the tub (20).
[0129] According to one embodiment, the garment treatment device (1) may not additionally secure a gap between the front frame (10b) of the housing (10) and the front of the tub (20) to form the supply passage (78), by extending the supply passage (78) forward from the front end of the drying base (70b) and then directly downward from the front end of the drying base (70b) toward the tub (20) without extending toward the tub (20). In other words, the garment treatment device (1) may be minimized or prevented from growing in the front-back direction to secure the supply passage (78).
[0130] The clothing treatment device (1) may include an exhaust path (P) for allowing air discharged from the tub (20) to flow to the drying device (70). The exhaust path (P) may be connected to an inlet path (76) of the drying device (70).
[0131] The exhaust path (P) may be provided to discharge moist air discharged from the inside of the drum (30) to the tub (20) to the outside of the tub (20). For example, the exhaust path (P) may be provided at the rear of the tub (20).
[0132] The exhaust path (P), the inlet path (76), the heating path (77), and the supply path (78) can circulate air into the interior of the tub (20) and the drying device (70).
[0133] In a garment treatment device (1) according to one embodiment, an exhaust path (P) may be formed by coupling an exhaust duct (100) to a tub bag (200). Specifically, the exhaust duct (100) may be formed by coupling a duct cover (120) to a duct body (110). The exhaust path (P) may be formed inside the exhaust duct (100). The structure in which the exhaust duct (100) is coupled to the tub bag (200) may be provided in various ways. '
[0134] The exhaust duct (100) may be provided to allow air discharged from the tub exhaust port (220) to flow in. The air discharged from the tub exhaust port (220) may flow into the interior of the duct body (110) through the duct exhaust port (1120) of the duct body (110). The air introduced through the duct exhaust port (1120) may flow into the drying device (70) along the exhaust path (P).
[0135] According to one embodiment, a tub (20) may include a reinforcing rib (201) and a cut rib (202) formed on the rear side of a tub back (200). The front side of the tub back (200) may refer to one side of the tub back (200) that is positioned inside the tub (20), and the rear side of the tub back (200) may refer to the other side of the tub back (200) that is positioned outside the tub (20).
[0136] A reinforcing rib (201) may be formed to reinforce the rigidity of the tub back (200). The reinforcing rib (201) may protrude rearward from the rear of the tub back (200). The cut rib (202) may protrude rearward from the rear of the tub back (200), but may have a lower protruding height than the reinforcing rib (201). The cut rib (202) may be manufactured to have a lower protruding height when the tub (20) is injection-molded. Alternatively, the cut rib (202) may be formed by cutting a predetermined length from an end of the reinforcing rib (201).
[0137] The heated air in the drying device (70) can be introduced into the tub (20) and then supplied into the drum (30). At this time, it is necessary to secure an area where the heated air supplied into the drum (30) comes into contact with the laundry. The longer the distance and time that the heated air flows inside the drum (30), the more it can come into contact with the laundry. To this end, the tub exhaust port (220) can be formed at a position opposite to the air inlet (26) through which the heated air in the drying device (70) is introduced into the tub (20).
[0138] The air inlet (26) through which heated air from the drying device (70) flows into the tub (20) and the tub exhaust port (220) through which air inside the tub (20) is discharged can be positioned as far apart as possible. For this purpose, the air inlet (26) and the tub exhaust port (220) can be positioned diagonally when looking at the tub (20) from the front or rear.
[0139] For example, if the air inlet (26) is formed at the upper front right of the tub (20) or at a position adjacent to the upper front right of the tub (20), the tub exhaust port (220) may be formed at the lower left of the tub back (200) or at a position adjacent to the lower left of the tub back (200). In this case, since the heated air moves from the upper front right of the tub (20) toward the lower left of the tub back (200), it may also move in a similar direction inside the drum (30) arranged inside the tub (20). That is, the heated air may move in a diagonal direction from the upper front right of the drum (30) toward the lower left of the rear of the drum (30). Through this, the movement path of the heated air inside the drum (30) may be made as long as possible. As the path of movement of the heated air becomes longer, the heated air can come into contact with the laundry inside the drum (30) over a wide area for a long time, and the drying efficiency of the clothing treatment device (1) can be improved.
[0140] However, without being limited thereto, the air inlet (26) and the tub exhaust port (220) may be provided at different locations depending on the area of the air inlet (26) and the tub exhaust port (220) and / or the air volume of the blower fan (78a).
[0141] The clothing treatment device (1) may include a duct cover (120) coupled to the tub (20) to cover the duct body (110).
[0142] An exhaust path (P) can be formed by a duct cover (120) covering an open side of a duct body (110). When the duct cover (120) is coupled to the duct body (110), an exhaust duct (100) forming an exhaust path (P) inside can be formed.
[0143] The duct body (110) may further include a duct connection portion (1140) protruding toward the upper side of the duct body (110). However, the present invention is not limited thereto, and the duct connection portion (1140) may be positioned in various ways depending on the location of the drying device (70).
[0144] The duct connection (1140) can be connected to the inlet guide (76a) of the drying device (70). The duct connection (1140) can extend the exhaust path (P) upward. The duct connection (1140) can form a portion of the exhaust path (P).
[0145] The duct connection portion (1140) can be formed in a rectangular parallelepiped shape with an open upper surface.
[0146] Since the exhaust path (P) is connected to the inlet path (76), air that is introduced into the exhaust path (P) through the tub exhaust port (220) formed in the tub back (200) can move along the exhaust path (P) and be introduced into the drying device (70) through the inlet path (76).
[0147] FIG. 6 is a rear view of a tub and an exhaust duct according to one embodiment of the present disclosure. FIG. 7 is an exploded view of a tub and a duct body according to one embodiment. FIG. 8 is an exploded view of a duct body and a duct cover according to one embodiment.
[0148] Referring to FIGS. 6 to 8, the tub (20) may include a tub back (200) forming the rear surface of the tub (20).
[0149] The tub back (200) may include a plurality of reinforcing ribs (201) formed to withstand the rotational force and hydraulic pressure of the driving device. The plurality of reinforcing ribs (201) may protrude from the tub back (200). Specifically, the plurality of reinforcing ribs (201) may protrude rearward from the tub back (200).
[0150] The plurality of reinforcing ribs (201) may include a plurality of annular ribs (201b) and a plurality of radial ribs (201a). The plurality of annular ribs (201b) may be arranged in a concentric circle shape centered on the center of the bearing housing (51). The plurality of radial ribs (201a) may be in a shape that extends radially from the center of the bearing housing (51).
[0151] A plurality of reinforcing ribs (201) may be formed in at least a portion of the tub back (200). The portion of the area forming the tub back (200) where the plurality of reinforcing ribs (201) are formed may be referred to as a first region (R1).
[0152] The tub back (200) may include cut ribs (202) that are lower in height than the reinforcing ribs (201) among a plurality of reinforcing ribs (201). The cut ribs (202) may be formed by cutting a portion of the reinforcing rib (201). Alternatively, the cut ribs (202) may be formed to have a lower height than the reinforcing ribs (201) when the tub (20) is injection-molded. The portion where the plurality of cut ribs (202) are formed may be referred to as a second region (R2).
[0153] Since the plurality of reinforcing ribs (201) and the plurality of cut ribs (202) have different heights, the first region (R1) and the second region (R2) can have different heights. The first region (R1) and the second region (R2) can be formed in steps.
[0154] The tub back (200) may be arranged so that the exhaust duct (100) is installed in the second region (R2). The second region (R2) may be formed to have a lower protruding height than the first region (R1). Therefore, even if the exhaust duct (100) is installed in the tub back (200), the length of the exhaust duct (100) protruding rearward can be reduced. In other words, the length of the exhaust duct (100) protruding rearward can be reduced when it is installed in the second region (R2) compared to when it is installed in the first region (R1).
[0155] The cutting ribs (202) of the second region (R2) of the tub back (200) may have a lower protruding height than the reinforcing ribs (201) of the first region (R1). That is, the rigidity of the second region (R2) of the tub back (200) may be weakened compared to the first region (R1).
[0156] The exhaust duct (100) may be provided to reinforce the rigidity of the tub (20). The exhaust duct (100) may include a material having a rigidity equivalent to that of the tub (20). Preferably, the exhaust duct (100) may include a material having a higher rigidity than the material forming the tub (20). For example, the exhaust duct (100) may include PPS, aluminum die casting (ALDC), steel plate, etc.
[0157] The exhaust duct (100) may include a duct body (110) that is mounted on a duct mounting portion (210). In addition, the exhaust duct (100) may include a duct cover (120) that is arranged to be coupled to the duct body (110). The duct body (110) may include a material that is equivalent to or stronger than the material forming the tub (20). However, the present invention is not limited thereto, and the duct cover (120) may also include a material that is equivalent to or stronger than the material forming the tub (20).
[0158] The exhaust duct (100) can be mounted on the duct mounting portion (210) and connected to the tub (20) and / or the bearing housing (51).
[0159] The exhaust duct (100) may include a tub coupling portion (2010, 2020) configured to be coupled with the tub (20).
[0160] The tub coupling portion (2010, 2020) may be formed along the periphery of the duct mounting portion (210). The tub coupling portion (2010, 2020) may include a first tub coupling portion (2010) formed on the outer side of the duct mounting portion (210). In other words, the first tub coupling portion (2010) may be formed along the outer circumference of the tub back (200). In another word, the first tub coupling portion (2010) may be formed along a cylindrical surface forming the tub (20).
[0161] The tub joint (2010, 2020) may include a second tub joint (2020) formed on the inside of the duct mounting portion (210). The second tub joint (2020) may be formed at a portion where the first region (R1) and the second region (R2) of the tub back (200) meet.
[0162] The duct body (110) may include a duct body coupling portion (1110) that is provided to correspond to the tub coupling portion (2010, 2020). The duct body coupling portion (1110) may be provided on a side surface of the duct body (110). That is, the duct body coupling portion (1110) may be provided on the circumferential surface of the duct body (110).
[0163] The duct body joint (1110) and the tub joint (2010, 2020) can be joined together by means of a fastening member. With the duct body (110) secured to the duct mounting member (210), a fastening member can be inserted into the duct body joint (1110) and the tub joint (2010, 2020) to be joined to each other.
[0164] The duct body coupling portion (1110) may include a first duct body coupling portion (1111) corresponding to the first tub coupling portion (2010). In addition, the duct body coupling portion (1110) may include a second duct body coupling portion (1112) corresponding to the second tub coupling portion (2020).
[0165] The exhaust duct (100) may include a duct joint (1210, 1220) where the duct body (110) and the duct cover (120) are joined.
[0166] The duct joint (1210, 1220) may include a first duct joint (1210) located farther from the center of the tub back (200) in the exhaust duct (100). The first duct joint (1210) may be a portion where the duct body (110) and the duct cover (120) are joined.
[0167] The duct joint (1210, 1220) may include a second duct joint (1220) located near the center and periphery of the tub back (200) in the exhaust duct (100). The second duct joint (1220) may be a portion where the duct body (110) and the duct cover (120) are joined.
[0168] The duct joint (1210, 1220) can be joined only with the duct body (110) and the duct cover (120). In addition, the duct cover (120) and the bearing housing (51) can be joined as one piece with the duct body (110) in between.
[0169] The duct joints (1210, 1220) can be joined in various ways. For example, the duct joints (1210, 1220) can be joined to the body joint holes (1151, 1152) and the cover joint holes (1251, 1252) through a fastening member. This is merely an example, and various other joining methods may be used.
[0170] Referring to FIGS. 7 and 8, the joint structure of the duct body (110) and the tub (20), and the duct body (110) and the duct cover (120) will be described.
[0171] Referring to FIG. 7, the tub back (200) may include a tub exhaust port (220) provided to discharge air inside the tub (20). The tub exhaust port (220) may be provided to discharge air containing moisture from laundry inside the tub (20).
[0172] A tub exhaust port (220) may be formed in the tub back (200). Specifically, the tub exhaust port (220) may be provided in a duct mounting portion (210). Air discharged through the tub exhaust port (220) may be arranged to flow into an exhaust duct (100) mounted on the duct mounting portion (210).
[0173] The interior of the tub (20) and the exhaust duct (100) can be connected so that air discharged through the tub exhaust port (220) flows through the exhaust duct (100). The exhaust duct (100) according to one embodiment of the present disclosure can include a duct exhaust port (1120) formed to correspond to the tub exhaust port (220).
[0174] The duct exhaust port (1120) may be provided so that air discharged from the tub exhaust port (220) can flow into the exhaust duct (100).
[0175] The duct body (110) may include a duct insert (1130) protruding toward the tub exhaust port (220). The duct insert (1130) may be inserted into the tub exhaust port (220). The duct insert (1130) may be configured to be inserted into the tub exhaust port (220) so that the duct body (110) is coupled to the tub (20).
[0176] The duct insert (1130) may be formed along the perimeter of the duct exhaust port (1120). The duct insert (1130) may protrude from the perimeter of the duct exhaust port (1120). Specifically, the duct insert (1130) may protrude toward the tub (20).
[0177] The duct insert (1130) may have a predetermined length so that it can be inserted into the tub exhaust port (220). The circumference of the duct insert (1130) may correspond to the circumference of the duct exhaust port (1120). The duct insert (1130) may be inserted into the tub exhaust port (220) to connect the interior of the tub (20) and the interior of the exhaust duct (100).
[0178] Air inside the tub (20) can flow into the exhaust duct (100) through the duct insert (1130) inserted into the tub exhaust port (220). The passage formed by the duct insert (1130) can be communicated with the duct exhaust port (1120).
[0179] The tub exhaust port (220) may include a first tub exhaust port (221) formed on the lower side of the duct body (110), a second tub exhaust port (222) formed above the first tub exhaust port (221), and a third tub exhaust port (223) formed above the second tub exhaust port (222).
[0180] The second tub exhaust port (222) may be formed at a position spaced upward from the first tub exhaust port (221). The second tub exhaust port (222) may be positioned above the first tub exhaust port (221). The second tub exhaust port (222) may be positioned below the center of the tub back (200). Since the second tub exhaust port (222) is positioned so that there is a gap between it and the first tub exhaust port (221), a decrease in the strength of the tub back (200) may be prevented compared to a case where the second tub exhaust port (222) and the first tub exhaust port (221) are formed integrally.
[0181] The third tub exhaust port (223) can be formed at a position spaced upward from the second tub exhaust port (222). Similarly, the air flow rate can be secured while preventing a decrease in the rigidity of the tub back (200).
[0182] In this way, the tub exhaust port (220) can be formed in three pieces. The duct exhaust port (1120) can also be formed in three pieces corresponding to the tub exhaust port (220). The duct insertion portion (1130) can also be formed in three pieces since it protrudes from each duct exhaust port (1120).
