[0051] The dryer (60) may include a second housing (61) that accommodates various components therein. The second housing (61) may have various shapes. For example, the second housing (61) may have a rectangular parallelepiped shape. A second door (63) may be provided on the front of the second housing (61).

[0052] The clothing handling system (1) may include a user interface (110). The user interface (110) may be provided in at least one of the washing machine (10) and the dryer (60). For example, the user interface (110) may be provided between the washing machine (10) and the dryer (60) that are arranged vertically.

[0053] The user interface (110) can obtain user input. The user interface (110) can include various buttons and / or rotatable dials. For example, the user interface (110) can include a power button for turning on or off the washing machine (10) and the dryer (60), respectively, a pause button for starting or pausing a washing operation and / or a drying operation, and a setting button for selecting a washing course, washing detailed settings, a drying course, and drying detailed settings, respectively. Depending on the rotation of the dial, one of a plurality of washing courses or one of a plurality of drying courses may be selected.

[0054] The user interface (110) can display various information related to the operation of the clothing handling system (1). For example, the user interface (110) can display operation information of the washing machine (10) and operation information of the dryer (60). The user interface (110) can display washing courses, washing detailed settings, washing time, drying courses, drying detailed settings, and / or drying time.

[0055] The user interface (110) may include a display. The display may be provided as a liquid crystal display (LCD) panel and / or a light emitting diode (LED) panel. The user interface (110) may also include a touch display. The various buttons described above may be provided through the touch display.

[0056] Although it is exemplified that a single user interface (110) is provided that can comprehensively control a washing machine (10) and a dryer (60), it is not limited thereto. The user interface for controlling the washing machine (10) and the user interface for controlling the dryer (60) may be provided separately.

[0057] The washing machine (10) may provide various washing courses depending on the design. The washing courses may include different washing settings depending on the type of laundry (e.g., blankets, underwear, etc.) and material (e.g., cotton, wool, etc.). For example, various washing courses may be provided, such as a standard course, a heavy course, a delicate course, a blanket course, a baby clothes course, a towel course, a small load course, a boil course, an energy-saving course, an outdoor clothing course, a rinse and spin course, and a rinse and spin course.

[0058] The drying cycle of the dryer (60) may vary depending on the design. The drying cycle may include different drying settings depending on the type and material of the object.

[0060] When the washing machine (10) operates according to the aforementioned washing course, the humidity inside the tub (20) becomes very high due to the water supplied to the tub (20) and the wet laundry existing inside the first drum (30). The humidity inside the tub (20) remains high until the first door (13) is opened after the operation of the washing machine (10) is completed. In addition, even after the laundry is taken out from the first drum (30), moisture remains inside the tub (20) and the first drum (30). When the first door (13) of the washing machine (10) is closed after the laundry is taken out, the moisture inside the tub (20) cannot be discharged to the outside.

[0061] If moisture remains inside the tub (20) and is left unattended, mold and bacteria may grow inside the tub (20). If a large amount of moisture contained inside the tub (20) is discharged into the indoor space (i.e., the space where the washing machine (10) is placed) immediately after the operation of the washing machine (10) is completed, mold and bacteria may grow in the indoor space due to the discharged moisture. If mold and bacteria grow, an unpleasant odor may occur in the tub (20) and the indoor space, and may also have a negative impact on the hygiene of the user. Therefore, the disclosed clothing treatment system (1) provides a tub drying course for removing moisture inside the tub (20) and the first drum (30).

The fan (90) may circulate air inside the second housing (61). The fan (90) may form a circulating airflow passing through the second drum (70) inside the second housing (61). Air heated by the heat pump (80) may flow by the operation of the fan (90). In addition, the fan (90) may suck air inside the second drum (70) and send the sucked air to the heat pump (80).

[0096] According to various embodiments, a fan motor for rotating the fan (90) may be provided separately from a second drum motor (73) for rotating the second drum (70). In addition, the second drum motor (73) may be connected to the second drum (70) and the fan (90) through different rotation axes, and may rotate both the second drum (70) and the fan (90). The rotation speed of the second drum (70) and the rotation speed of the fan (90) may be independently controlled.

[0097] The second drum (70) may include an inlet (71) through which air is introduced into the interior of the second drum (70). Air inside the second drum (70) may be discharged to the exterior of the second drum (70) through the second drum opening (72). The inlet (71) may be located on the opposite side of the second drum (70) from the side where the second drum opening (72) is located. For example, the inlet (71) may be located at the rear of the second drum (70), and the second drum opening (72) may be located at the front of the second drum (70).

[0098] A guide duct (77) may be provided at the rear of the second housing (61) to guide hot air generated by the heat pump (80) into the interior of the second drum (70). The guide duct (77) may be formed integrally with the second housing (61) or may be coupled to the rear of the second housing (61). The guide duct (77) may be connected to the heating duct (76).

[0099] While the dryer (60) performs the drying process, air heated by the heat pump (80) sequentially passes through the heating duct (76) and the guide duct (77), and can enter the interior of the second drum (70) through the inlet (71) formed at the rear of the second drum (70).

[0100] A filter duct (75) may be provided in front of the second drum (70). Air discharged from the second drum (70) through the second drum opening (72) may pass through the filter duct (75). The air passing through the filter duct (75) may enter the filter device (96). Lint contained in the air may be filtered by the filter device (96). The air passing through the filter duct (75) and the filter device (96) may be again introduced into the heating duct (76).

[0101] The filter device (96) can be mounted inside the second housing (61) through the housing opening (69). The filter device (96) can be detachably mounted in the filter receiving portion (68) formed inside the second housing (61). Lint generated during the drying process of the object to be dried can be stored in the filter device (96).

[0102] The first duct (101) can form a first flow path for moving hot air generated by the heat pump (80) of the dryer (60) to the tub (20) of the washing machine (10). One end of the first duct (101) can pass through the lower side of the rear surface (61b) of the second housing (61) of the dryer (60). When the guide duct (77) and the second housing (61) are formed integrally, one end of the first duct (101) can pass through the lower side of the guide duct (77). One end of the first duct (101) can be connected to a heating duct (76) provided inside the second housing (61).

[0103] The other end of the first duct (101) may be connected to the upper front of the tub (20) of the washing machine (10). A through hole connected to the first duct (101) may be provided at the upper front of the tub (20). Hot air passing through the first duct (101) may be introduced into the tub (20) through the upper front of the tub (20). The hot air introduced into the tub (20) may enter the first drum (30) through the plurality of through holes (34) of the first drum (30). The hot air introduced into the tub (20) and the first drum (30) may dry the tub (20) and the first drum (30).

[0104] One end of the second duct (102) may be connected to the lower rear of the tub (20). An exhaust port connected to the second duct (102) may be provided at the lower rear of the tub (20). The other end of the second duct (102) may pass through the upper side of the rear (61b) of the dryer (60). When the guide duct (77) and the second housing (61) are formed integrally, the other end of the second duct (102) may pass through the upper side of the guide duct (77). The other end of the second duct (102) may be adjacent to the rear of the second drum (70).

[0105] Moisture inside the tub (20) and the first drum (30) is discharged to the lower rear of the tub (20) and can move to the second drum (70) of the dryer (60) through the second duct (102). The moisture flows along the second duct (102) and can enter the second drum (70) through the inlet (71) of the second drum (70). The air containing moisture can pass through the filter duct (75) and enter the heating duct (76). The moisture is removed by condensation in the evaporator (81), and the dry air is heated in the condenser (82).

[0106] The other end of the first duct (101) connected to the upper front of the tub (20) and the one end of the second duct (102) connected to the lower rear of the tub (20) may be positioned diagonally. That is, the through hole of the tub (20) through which hot air is introduced and the exhaust port of the tub (20) through which moisture is discharged may be positioned diagonally.

[0107] In this way, by supplying hot air to the upper front of the tub (20) and causing the air inside the tub (20) to be discharged to the lower rear of the tub (20), the drying effect of the tub (20) and the first drum (30) by the hot air can be improved. That is, by allowing the hot air to reach from the upper part of the tub (20) to the lower part of the tub (20), overall drying of the tub (20) and the first drum (30) becomes possible.

[0108] A first damper (101a) for opening or closing the first duct (101) may be provided inside the first duct (101). A second damper (78) for opening or closing the guide duct (77) may be provided inside the guide duct (77). The operations of the first damper (101a) and the second damper (78) may be controlled by the first control unit (200) of the washing machine (10) or the second control unit (400) of the dryer (60), which will be described later.

[0109] The dryer (60) can perform a drying process to dry clothes contained in the second drum (70). When a drying course is selected through the user interface (110), the dryer (60) can perform a drying process corresponding to the selected drying course.

[0110] While the dryer (60) performs a drying process, the first damper (101a) may be controlled to close the first duct (101), and the second damper (78) may be controlled to open the guide duct (77). That is, during the drying process of the dryer (60), the first damper (101a) may be closed, and the second damper (78) may be opened. In this case, the hot air generated by the heat pump (80) may be supplied to the inside of the second drum (70) of the dryer (60) through the guide duct (77), and may not be supplied to the tub (20) of the washing machine (10). The air may circulate inside the second housing (61) of the dryer (60).

[0111] The washing machine (10) can perform a tub drying process to dry the tub (20) and the first drum (30). If the humidity within the tub (20) is higher than or equal to a predetermined reference humidity, the washing machine (10) can automatically perform the tub drying process. In addition, if a tub drying course is selected through the user interface (110), the washing machine (10) can perform the tub drying process based on the humidity within the tub (20).

[0112] While the washing machine (10) performs the tub drying cycle, the first damper (101a) may be controlled to open the first duct (101), and the second damper (78) may be controlled to close the guide duct (77). That is, during the tub drying cycle of the washing machine (10), the first damper (101a) may be opened, and the second damper (78) may be closed. In this case, the hot air generated by the heat pump (80) may be supplied to the inside of the tub (20) through the first duct (101), and may not be supplied to the second drum (70) of the dryer (60). As hot air is supplied into the tub (20), moisture inside the tub (20) and the first drum (30) is discharged to the lower rear of the tub (20) and can move to the second drum (70) of the dryer (60) through the second duct (102). Air can circulate inside the tub (20) of the washing machine (10) and the second housing (61) of the dryer (60).

[0113] In addition, when clothes are accommodated inside the first drum (30) of the washing machine (10), a tub drying process may be performed to dry the clothes accommodated inside the first drum (30). That is, both washing and drying of clothes may be performed by the washing machine (10). Separately from the tub drying course, a clothes drying course of the washing machine (10) for drying clothes accommodated inside the first drum (30) of the washing machine (10) may be provided. The clothes drying course and the tub drying course may include different drying settings. For example, at least one of a drying temperature and a drying time may be set differently in the clothes drying course and the tub drying course.

[0114] In the clothes drying course and the tub drying course, the hot air supply path and the moisture discharge path can be formed in the same manner. That is, the hot air supply path can be formed by the first duct (101) illustrated in FIG. 5, and the moisture discharge path can be formed by the second duct (102). In the clothes drying course and the tub drying course, the first damper (101a) can be controlled to open the first duct (101), and the second damper (78) can be controlled to close the guide duct (77).

[0115] Figure 6 illustrates a cross-section of a garment processing system according to another embodiment.

[0116] Comparing Fig. 6 with Fig. 5, the structures of the duct for discharging moisture inside the tub (20) and the first drum (30) are different. The second duct (102) of Fig. 5 and the third duct (103) of Fig. 6 can be replaced with each other.

[0117] In Fig. 5, the second duct (102) corresponding to the moisture discharge duct can pass through the guide duct (77) on the upper side of the rear surface (61b) of the dryer (60). However, in Fig. 6, the third duct (103) corresponding to the moisture discharge duct can be arranged below the first drum (30). The third duct (103) can be located between the first drum (30) and the heating duct (76). One end of the third duct (103) can be connected to the lower rear surface of the tub (20), and the other end of the third duct (103) can be connected to the filter duct (75) arranged in front of the first drum (30). The third duct (103) can pass through the rear surface (61b) of the second housing (61). When the second housing (61) and the guide duct (77) are formed integrally, the third duct (103) can pass through the guide duct (77).

[0118] Additionally, in FIG. 6, a third damper (79) may be provided in the filter duct (75) to open or close the filter duct (75). The operation of the third damper (79) may be controlled by the first control unit (200) of the washing machine (10) or the second control unit (400) of the dryer (60).

[0119] While the dryer (60) is performing a drying process, the third damper (79) can be controlled to open the filter duct (75). During the drying process of the dryer (60), the first damper (101a) can be closed, and the second damper (78) and the third damper (79) can be opened. Accordingly, air can circulate inside the second housing (61) of the dryer (60).

[0120] While the washing machine (10) performs the tub drying cycle, the third damper (79) can be controlled to close the filter duct (75). In the tub drying cycle of the washing machine (10), the first damper (101a) can be opened, and the second damper (78) and the third damper (79) can be closed. By closing the third damper (79), moist air flowing into the filter duct (75) through the third duct (103) can be prevented from flowing into the second drum (70) of the dryer (60). That is, moist air discharged from the tub (20) can pass through the heat pump (80) without passing through the second drum (70) of the dryer (60). Therefore, the air can circulate through the heat pump (80) of the dryer (60) and the tub (20) of the washing machine (10).

[0121] The third damper (79) is not an essential component. When the fan (90) operates while the second damper (78) is closed, moist air flowing into the filter duct (75) through the third duct (103) may be sucked in by the fan (90). Since a path passing through the second drum (70) of the dryer (60) is not formed, moist air may not flow into the second drum (70) of the dryer (60).

[0122] In addition, when clothes are accommodated inside the first drum (30) of the washing machine (10), a tub drying process may be performed to dry the clothes accommodated inside the first drum (30). That is, both washing and drying of clothes may be performed by the washing machine (10). Separately from the tub drying course, a clothes drying course of the washing machine (10) for drying clothes accommodated inside the first drum (30) of the washing machine (10) may be provided. The clothes drying course and the tub drying course may include different drying settings. For example, at least one of a drying temperature and a drying time may be set differently in the clothes drying course and the tub drying course.

[0123] In the clothes drying course and the tub drying course, the hot air supply path and the moisture discharge path can be formed in the same manner. That is, the hot air supply path can be formed by the first duct (101) illustrated in Fig. 6, and the moisture discharge path can be formed by the third duct (103). In the clothes drying course and the tub drying course, the first damper (101a) can be opened, and the second damper (78) and the third damper (79) can be closed.

[0124] Figure 7 illustrates the operation of a heat pump in a clothing treatment system according to one embodiment.

[0125] Referring to FIG. 7, a heat pump (80) may include a compressor (83), a condenser (82), an expander (84), and an evaporator (81). The compressor (83), the condenser (82), the expander (84), and the evaporator (81) may be connected to each other via refrigerant pipes to form a heat pump cycle. The refrigerant may circulate according to the heat pump cycle while flowing through the refrigerant pipes. When the compressor (83) operates, the refrigerant may circulate along the refrigerant pipes.

[0126] The compressor (83) compresses low-temperature, low-pressure gaseous refrigerant and discharges it as high-temperature, high-pressure gaseous refrigerant. For example, the compressor (161) can compress the refrigerant through the reciprocating motion of a piston or the rotary motion of a rotor. The discharged gaseous refrigerant can be delivered to the condenser (82).

[0127] The condenser (82) can condense a high-temperature, high-pressure gaseous refrigerant into a liquid or near-liquid refrigerant having a high pressure lower than the condensation temperature. The condenser (82) can release heat to the surroundings through the condensation process of the refrigerant. The condenser (82) can heat air through the heat generated during the condensation process of the refrigerant. The liquid refrigerant condensed in the condenser (82) can be transferred to the expander (84). As the operating frequency and / or rotational speed (RPM) of the compressor (83) increases, the heat released to the surroundings of the condenser (82) can increase.

[0128] The high-temperature, high-pressure liquid refrigerant condensed in the condenser (82) is expanded and decompressed in the expander (84). For example, the expander (84) may include an electronic expansion valve whose opening amount can be varied by a capillary tube and an electric signal to control the pressure of the liquid refrigerant. The low-temperature, low-pressure two-phase refrigerant that has passed through the expander (84) is introduced into the evaporator (81).

[0129] The evaporator (81) can evaporate the two-phase refrigerant introduced from the expander (84). As a result, the evaporator (81) can return the low-temperature, low-pressure refrigerant to the compressor (83). The evaporator (81) can absorb heat from the surroundings through an evaporation process that changes the low-pressure two-phase refrigerant into a gaseous refrigerant. The evaporator (81) can cool the air passing through the evaporator (81) during the evaporation process.

[0130] When the surrounding air is cooled by the evaporator (81), and the temperature of the surrounding air becomes lower than the dew point, the air around the evaporator (81) may condense. The water condensed in the evaporator (81) may fall due to gravity and be received in a water receiving tank provided at the bottom of the evaporator (81). Some of the water condensed in the evaporator (81) may remain in the evaporator (81) due to surface tension.

[0131] As condensation occurs around the evaporator (81), the absolute humidity of the air passing through the evaporator (81) may decrease. In other words, the amount of moisture contained in the air passing through the evaporator (81) may decrease. By utilizing condensation around the evaporator (81), the clothing treatment system (1) may reduce the amount of moisture contained in the air inside the drum (70) of the dryer (60) and / or the tub (20) of the washing machine (10).

[0132] The evaporator (81) may be located upstream of the condenser (82) based on the air flow by the fan (90). Air sucked from the drum (70) of the dryer (60) or the tub (20) of the washing machine (10) is dried (water vapor is condensed) by the evaporator (81) while passing through the evaporator (81). In addition, the temperature of the air decreases as it passes through the evaporator (81).

[0133] Air passing through the evaporator (81) moves toward the condenser (82). As previously described, the condenser (82) can release heat while the refrigerant is condensed. Therefore, the air passing through the evaporator (81) can be heated by the condenser (82) while passing through the condenser (82).

[0134] The air heated by the condenser (82) can be introduced into the drum (70) of the dryer (60) or the tub (20) of the washing machine (10). The heated air can absorb moisture while passing through the drum (70) of the dryer (60) or the tub (20) of the washing machine (10). The air that has absorbed moisture can move back to the evaporator (81). The air can remove moisture inside the drum (70) of the dryer (60) and / or the tub (20) of the washing machine (10) while circulating inside the drum (70) of the dryer (60) and / or the tub (20) of the washing machine (10).

For example, the user can select a washing course of the washing machine (10) or a drying course of the dryer (60) by operating the user interface (110). The user interface (110) can display washing course information and washing setting information (e.g., washing temperature, number of rinses, spin strength) corresponding to the washing course based on the selection of the washing course. The user interface (110) can display drying course information and drying setting information (e.g., drying temperature, drying time) corresponding to the drying course based on the selection of the drying course.

The first humidity sensor (120) can also be located within the first drum (30). The first humidity sensor (120) can transmit an electrical signal corresponding to the detected humidity to the first control unit (200). Whether or not to perform the tub drying process can be determined based on the humidity detected by the first humidity sensor (120).

[0145] The door driving device (140) can adjust the opening angle of the first door (13). The door driving device (140) can be provided together with the first hinge (14). The door driving device (140) can include a gear and a motor for rotating the first door (13). The first control unit (200) can automatically open or close the first door (13) by controlling the door driving device (140).

[0146] The first communication interface (150) may include various communication circuits for performing wired and / or wireless communication with external devices (e.g., servers, user devices, and / or other home appliances). The user devices may include various electronic devices such as smartphones, laptops, notebooks, smartwatches, stationary tablets, and speakers. Other home appliances may include a dryer (60). User input may be obtained through the user interface (110) as well as the user devices.

[0147] The first communication interface (150) may include at least one of a short-range communication circuit and a long-range communication circuit. The first communication interface (150) may transmit data to an external device or receive data from an external device. For example, the first communication interface (150) may support cellular communication, wireless local area network (WLAN), home radio frequency (RF), infrared communication, ultra-wide band (UWB) communication, Wi-Fi, Wi-Fi direct, Bluetooth, AD-HOC, and / or Zigbee.

[0148] The first communication interface (150) can also communicate with external devices via an access point (AP). The access point can connect the local area network (LAN) to which the washing machine (10) is connected to a wide area network (WAN) to which the server is connected. The washing machine (10) can be connected to the server via the wide area network (WAN).

[0149] The sterilizing device (160) can sterilize the tub (20) and the first drum (30). For example, the sterilizing device (160) may include an ultraviolet light source that irradiates ultraviolet light. The sterilizing device (160) may include at least one of a heater, an infrared lamp, or a UV-LED.

The other home appliances may include a washing machine (10). The second communication interface (330) may include at least one of a short-range communication circuit and a long-range communication circuit. The second communication interface (330) may transmit data to the external device or receive data from the external device. For example, the second communication interface (330) may support cellular communication, wireless local area network (WLAN), home radio frequency (RF), infrared communication, ultra-wide band (UWB) communication, Wi-Fi, Wi-Fi direct, Bluetooth, AD-HOC, and / or Zigbee. The communication technologies supported by the second communication interface (330) are not limited to those exemplified.

[0163] The second communication interface (330) can also communicate with external devices via an access point (AP). The access point can connect the local area network (LAN) to which the dryer (60) is connected to a wide area network (WAN) to which the server is connected. The dryer (60) can be connected to the server via the wide area network (WAN).

[0164] The second control unit (400) may include a second processor (410) and a second memory (420). The second memory (420) may include volatile memory (e.g., S-RAM, D-RAM) and non-volatile memory (e.g., ROM, EPROM). The second processor (410) and the second memory (420) may be implemented as separate chips or as a single chip. In addition, a plurality of processors and a plurality of memories may be provided. The second processor (410) may process various data and various signals using instructions, data, programs, and / or software stored in the second memory (420). The second processor (410) may include one core or a plurality of cores. The second processor (410) may generate control signals for controlling components of the dryer (60).

[0165] The second control unit (400) can be electrically connected to various components of the dryer (60) and can control the components of the dryer (60). The second control unit (400) can control the components of the washing machine (10) to perform a drying process according to user input.

[0166] The second control unit (400) of the dryer (60) can control the first damper (101a), the second damper (78), and the third damper (79). It is exemplified that the first damper (101a), the second damper (78), and the third damper (79) are controlled by the second control unit (400) of the dryer (60), but is not limited thereto. The first damper (101a), the second damper (78), and the third damper (79) may also be controlled by the first control unit (200) of the washing machine (10).

[0167] Figure 10 is a control block diagram of a garment processing system according to one embodiment.

[0168] Referring to FIG. 10, the clothing handling system (1) may include a washing machine (10), a dryer (60), and a user interface (110). The washing machine (10) and the dryer (60) may be electrically connected. The washing machine (10) and the dryer (60) may exchange electrical signals (e.g., control signals), information, and / or data.

[0169] The washing machine (10) and the dryer (60) can communicate via a first communication interface (150) and a second communication interface (330). For example, the first communication interface (150) and the second communication interface (330) can directly communicate with each other using a D2D wireless communication module (e.g., a Bluetooth module). The first communication interface (150) and the second communication interface (330) can be connected to a wide area network (WAN) and can communicate via a server.

[0170] A connection circuit (113) may be provided for wired connection between the first communication interface (150) and the second communication interface (330). The connection circuit (113) may include a connector for connection between the first communication interface (150) and the second communication interface (330).

[0171] The connection circuit (113) can transmit a signal transmitted from the first control unit (200) through the first communication interface (150) to the second control unit (400) through the second communication interface (330). The connection circuit (113) can transmit a signal transmitted from the second control unit (400) through the second communication interface (330) to the first control unit (200) through the first communication interface (150).

[0172] The first control unit (200) of the washing machine (10) can generate not only a control signal for controlling a component of the washing machine (10) but also a control signal for controlling at least one component of the dryer (60). The second control unit (400) of the dryer (60) can also generate a control signal for controlling at least one component of the washing machine (10) but also a control signal for controlling a component of the dryer (60).

[0173] The user interface (110) may be provided in the washing machine (10) and / or the dryer (60). For example, the user interface (110) may be provided between the washing machine (10) and the dryer (60) which are arranged vertically. The user interface (110) may be arranged on the upper front side of the first housing (11) of the washing machine (10).

[0174] Although it is exemplified that a single user interface (110) is provided that can comprehensively control a washing machine (10) and a dryer (60), it is not limited thereto. A user interface for controlling the washing machine (10) and a separate user interface for controlling the dryer (60) may also be provided.

[0175] The user interface (110) may include an input interface (111), an output interface (112), and a connection circuit (113). In addition, the user interface (110) may include a control unit capable of controlling both the washing machine (10) and the dryer (60).

[0176] The input interface (111) can obtain user input. The input interface (111) can transmit an electrical signal corresponding to the user input to the first control unit (200) of the washing machine (10) and / or the second control unit (400) of the dryer (60). The input interface (111) can include various buttons and / or a rotatable dial.

[0177] The output interface (112) may include at least one of a display and a speaker. The output interface (112) may be provided as a liquid crystal display (LCD) panel and / or a light emitting diode (LED) panel. The output interface (112) may also include a touch display.

[0178] The output interface (112) can receive information related to the operation of the washing machine (10) from the first control unit (200) through the first communication interface (150) of the washing machine (10). The output interface (112) can receive information related to the operation of the dryer (60) from the second control unit (400) through the second communication interface (330) of the dryer (60).

[0179] The output interface (112) can output various information related to the operation of the clothing handling system (1). The output interface (112) can display information related to the operation of the washing machine (10) and information related to the operation of the dryer (60). For example, the output interface (112) can display a washing course, washing detailed settings, washing time, drying course, drying detailed settings, and / or drying time.

[0180] The output interface (112) can display washing course information and washing setting information (e.g., washing temperature, number of rinses, spin-drying intensity) corresponding to the washing course based on selection of a washing course for operating the washing machine (10) through the input interface (111). The output interface (112) can display drying course information and drying setting information (e.g., drying temperature, drying time) corresponding to the drying course based on selection of a drying course for operating the dryer (60) through the input interface (111).

[0181] As described above, the clothing treatment system (1) can perform a tub drying process to remove moisture inside the tub (20) and the first drum (30) of the washing machine (10). The user interface (110) can obtain a user input for selecting a tub drying process. When the tub drying process is selected, the first control unit (200) or the second control unit (400) can determine whether to perform the tub drying process based on the humidity inside the tub (20) detected by the first humidity sensor (120).

[0182] The first control unit (200) or the second control unit (400) can perform a tub drying process based on whether the detected humidity within the tub (20) is higher than or equal to a predetermined reference humidity. The reference humidity can be determined in various ways depending on the design. Even if a tub drying course is not selected through the user interface (110), the tub drying process can be automatically performed based on whether the humidity within the tub (20) is higher than or equal to a predetermined reference humidity.

[0183] The first control unit (200) or the second control unit (400) can control the first humidity sensor (120) to detect humidity inside the tub (20) when the first door (13) of the washing machine (10) is closed. By detecting humidity inside the tub (20) when the first door (13) is closed, the accuracy of humidity detection can be increased. The first control unit (200) or the second control unit (400) can identify whether the first door (13) is open or closed based on a signal transmitted from the first door sensor (130).

[0184] The first control unit (200) or the second control unit (400) can determine whether to perform the tub drying process after the operation of the washing machine (10) for washing laundry accommodated in the first drum (30) is completed. The first control unit (200) or the second control unit (400) can identify the completion of the operation of the washing machine (10) for washing laundry. For example, after the washing process corresponding to the washing course selected through the user interface (110) is completed, the first control unit (200) or the second control unit (400) can determine whether the tub drying process needs to be performed. The first control unit (200) or the second control unit (400) can control the first humidity sensor (120) to detect the humidity inside the tub (20) while the first door (13) is closed after the washing process is completed.

[0185] The state in which the first door (13) is closed after the washing process is completed may include a state in which the first door (13) is closed while the laundry remains in the first drum (30) and a state in which the first door (13) is closed after the laundry is discharged from the first drum (30).

[0186] When the tub drying cycle of the washing machine (10) is performed while the laundry remains inside the first drum (30), the effect of removing water vapor floating inside the tub (20) and the first drum (30) can be achieved. In addition, the laundry contained inside the first drum (30) can also be dried.

[0187] When the tub drying process is performed after the laundry is discharged from the first drum (30), the effect of drying the tub (20) and the first drum (30) as a whole can be achieved.

[0188] When laundry is in the first drum (30), the drying setting of the tub drying process may be different from the drying setting of the tub drying process when laundry is not in the first drum (30). For example, when laundry is in the first drum (30), the first control unit (200) or the second control unit (400) may set the drying temperature to be relatively high. When laundry is in the first drum (30), the first control unit (200) or the second control unit (400) may set the drying time to be relatively long. In addition, depending on whether laundry is in the first drum (30), the first control unit (200) or the second control unit (400) may adjust the rotation speed of the first drum (30), the operating frequency of the compressor (83), and / or the rotation speed of the fan (90) in the tub drying process.

[0189] The first control unit (200) or the second control unit (400) can open the first damper (101a) provided in the first duct (101) and operate the heat pump (80) and the fan (90) based on determining whether to perform the tub drying process. Operating the heat pump (80) includes operating the compressor (83) and controlling the expander (84). Accordingly, hot air generated by the heat pump (80) can be introduced into the tub (20) through the first duct (101), and moisture within the tub (20) can be introduced into the second housing (61) of the dryer (60) through the second duct (102).

[0190] The first control unit (200) or the second control unit (400) may close the second damper (78) provided in the guide duct (77) to block the supply of hot air to the second drum (70) based on determining whether to perform the tub drying process. When the second damper (78) is closed, hot air cannot flow to the guide duct (77), and the supply of hot air to the second drum (70) of the dryer (60) may be blocked. Accordingly, heat loss may be reduced.

[0191] When the clothing treatment system (1) has a structure in which the moisture discharge duct (the third duct (103) of FIG. 6) is connected to the filter duct (75) (see FIG. 6), the first control unit (200) or the second control unit (400) may close the third damper (79) provided in the filter duct (75) to block moisture from flowing into the second drum (70) through the filter duct (75) based on determining whether to perform the tub drying process. However, as described above, the third damper (79) is not an essential component.

[0192] In addition, the first control unit (200) or the second control unit (400) can control the first drum motor (41) so that the first drum (30) of the washing machine (10) rotates in the tub drying cycle. The first control unit (200) or the second control unit (400) can control the second drum motor (73) so that the rotation of the second drum (70) of the dryer (60) stops in the tub drying cycle. As the first drum (30) of the washing machine (10) rotates, the effect of hot air can be applied to the entire first drum (30). Therefore, the drying effect of the first drum (30) can be improved.

[0193] The first control unit (200) or the second control unit (400) may stop the operation of the heat pump (80) and the operation of the fan (90) based on whether the humidity inside the tub (20) becomes lower than a predetermined reference humidity as a result of the tub drying process. That is, if the humidity inside the tub (20) becomes lower than the reference humidity, the operation of the compressor (83) may be stopped. In addition, if the humidity inside the tub (20) becomes lower than the reference humidity, the rotation of the first drum (30) may also be stopped.

[0194] The first control unit (200) or the second control unit (400) can control the door driving device (140) to open the first door (13) of the washing machine (10) based on the completion of the tub drying process. The clothing treatment system (1) can lower the temperature of the tub (20) and improve the drying effect of the tub (20) by automatically opening the first door (13) of the washing machine (10) after removing water vapor and / or moisture within the tub (20) of the washing machine (10).

[0195] Meanwhile, the user interface (110) can obtain a user input for selecting a clothes drying course for drying clothes accommodated in the first drum (30) of the washing machine (10). When the clothes drying course is selected, the first control unit (200) or the second control unit (400) can determine whether to perform a clothes drying process based on the humidity in the tub (20) detected by the first humidity sensor (120) and whether clothes are present in the first drum (30).

[0196] The presence of clothing within the first drum (30) can be determined in various ways. For example, the presence of clothing within the first drum (30) can be identified using a weight sensor, vibration of the tub (20), and / or the rotational speed of the first drum (30). Additionally, the clothing drying process can be automatically performed based on the humidity within the tub (20) and the presence of clothing within the first drum (30).

[0197] The clothes drying course and the tub drying course may include different drying settings. For example, at least one of the drying temperature and drying time may be set differently in the clothes drying course and the tub drying course. Furthermore, the rotation speed of the first drum (30), the operating frequency of the compressor (83), and / or the rotation speed of the fan (90) may also be set differently in the clothes drying course and the tub drying course.

[0198] Fig. 11 is a flowchart illustrating a control method of a clothing processing system according to one embodiment.

[0199] Referring to FIG. 11, the first control unit (200) of the clothing handling system (1) can identify the completion of the washing machine (10)'s operation for washing laundry (1101). For example, the first control unit (200) can identify the completion of the washing cycle of the washing machine (10).

[0200] The first control unit (200) can control the first humidity sensor (120) to detect humidity within the tub (20) of the washing machine (10) (1102). The first control unit (200) can detect humidity within the tub (20) by controlling the first humidity sensor (120) while the first door (13) is closed. For example, humidity within the tub (20) can be detected while the first door (13) is closed while laundry remains within the first drum (30). Humidity within the tub (20) can also be detected while the first door (13) is closed after laundry has been discharged from the first drum (30).

[0201] The first control unit (200) can compare the humidity within the tub (20) detected by the first humidity sensor (120) with a predetermined reference humidity (1103). Based on the detected humidity within the tub (20) being higher than or equal to the reference humidity, the first control unit (200) can perform a tub drying process (1104).

[0202] If the detected humidity within the tub (20) is lower than the reference humidity, the first control unit (200) may not perform the tub drying process. If the humidity within the tub (20) becomes lower than the preset reference humidity as a result of performing the tub drying process, the first control unit (200) or the second control unit (400) may terminate the tub drying process.

[0203] When the tub drying cycle of the washing machine (10) is performed while the laundry remains in the first drum (30), the effect of removing water vapor floating inside the tub (20) and the first drum (30) can be achieved. Accordingly, even if the first door (13) is opened immediately after the operation of the washing machine (10) for washing the laundry is completed, a large amount of water vapor inside the tub (20) can be prevented from being discharged into the indoor space.

[0204] When the tub drying process is performed after laundry is discharged from the first drum (30), the effect of drying the tub (20) and the first drum (30) as a whole can be achieved. That is, moisture remaining in the tub (20) and the first drum (30) can be removed, and the tub (20) and the first drum (30) can be maintained clean.

[0205] Fig. 12 is a flowchart illustrating a first embodiment of the tub drying process described in Fig. 11.

[0206] Referring to Fig. 12, the first control unit (200) of the clothing treatment system (1) can open the first damper (101a) provided in the hot air supply duct (i.e., the first duct (101)) based on entering the tub drying process (1201). The opening of the first damper (101a) may also be performed by the second control unit (200).

[0207] The first control unit (200) can operate the heat pump (80) and the fan (90) to generate hot air (1202). The first control unit (200) can directly control the heat pump (80) and the fan (90), or transmit a control signal to the second control unit (400) to operate the heat pump (80) and the fan (90). Operating the heat pump (80) includes operating the compressor (83) and controlling the expander (84). Accordingly, the hot air generated by the heat pump (80) can be introduced into the tub (20) through the first duct (101), and moisture within the tub (20) can be introduced into the second housing (61) of the dryer (60) through the second duct (102).

[0208] Additionally, the first control unit (200) can control the first drum motor (41) to rotate the first drum (30) of the washing machine (10) (1203). As the first drum (30) of the washing machine (10) rotates, the effect of hot air can be applied to the entire first drum (30). Therefore, the drying effect of the first drum (30) can be improved.

[0209] When the humidity inside the tub (20) becomes lower than the reference humidity as the tub drying process is performed, the first control unit (200) or the second control unit (400) can stop the operation of the heat pump (80) and the operation of the fan (90). In addition, the first control unit (200) or the second control unit (400) can also stop the rotation of the first drum (30).

[0210] Fig. 13 is a flowchart illustrating a second embodiment of the tub drying process described in Fig. 11.

[0211] Referring to FIG. 13, the first control unit (200) of the clothing treatment system (1) can open the first damper (101a) provided in the hot air supply duct (i.e., the first duct (101)) based on entering the tub drying cycle (1301). In addition, the first control unit (200) can close the second damper (78) provided in the guide duct (77) (1302). When the second damper (78) is closed, hot air cannot flow to the guide duct (77), and the supply of hot air to the second drum (70) of the dryer (60) can be blocked. Therefore, heat loss can be reduced.

[0212] Opening of the first damper (101a) and closing of the second damper (78) may also be performed by the second control unit (200).

[0213] The first control unit (200) or the second control unit (400) can operate the heat pump (80) and the fan (90) to generate hot air (1303). In addition, the first control unit (200) can control the first drum motor (41) to rotate the first drum (30) of the washing machine (10) (1303).

[0214] Fig. 14 is a flowchart illustrating a third embodiment of the tub drying process described in Fig. 11.

[0215] A third embodiment of the tub drying process can be performed when the clothing treatment system (1) has a structure in which the moisture discharge duct (the third duct (103) of FIG. 6) is connected to the filter duct (75) (see FIG. 6).

[0216] Referring to FIG. 14, the first control unit (200) of the clothing treatment system (1) can open the first damper (101a) provided in the hot air supply duct (i.e., the first duct (101)) based on entering the tub drying process (1401). The first control unit (200) can close the second damper (78) provided in the guide duct (77) (1402). In addition, the first control unit (200) can close the third damper (79) provided in the filter duct (75) (1403). When the third damper (79) is closed, moisture can be prevented from flowing into the second drum (70) through the filter duct (75).

[0217] The opening of the first damper (101a), the closing of the second damper (78), and the closing of the third damper (79) may be performed by the second control unit (200).

[0218] The first control unit (200) or the second control unit (400) can operate the heat pump (80) and the fan (90) to generate hot air (1404). In addition, the first control unit (200) can control the first drum motor (41) to rotate the first drum (30) of the washing machine (10) (1405).

[0219] As described above, the third damper (79) is not an essential component. When the fan (90) operates while the second damper (78) is closed, moist air flowing into the filter duct (75) through the third duct (103) can be sucked by the fan (90). Since a path passing through the second drum (70) of the dryer (60) is not formed, the moist air may not flow into the second drum (70) of the dryer (60). When the third damper (79) is provided, the introduction of moist air into the second drum (70) of the dryer (60) can be completely blocked.

[0220] In this way, the disclosed clothing handling system (1) can keep the tub (20) and the first drum (30) of the washing machine (10) clean by removing water vapor and / or moisture remaining inside the tub (20) and the first drum (30). That is, the disclosed clothing handling system (1) can suppress the growth of mold and bacteria in the tub (20) and the first drum (30) by performing a tub drying process. In addition, the disclosed clothing handling system (1) can also suppress the growth of mold and bacteria in the indoor space by preventing a large amount of water vapor inside the tub (20) from being discharged into the indoor space immediately after the washing machine (10) completes its operation for washing laundry.

[0221] Fig. 15 is a flowchart explaining a control method of a clothing processing system that continues from Fig. 11.

[0222] Referring to FIG. 15, the first control unit (200) of the clothing treatment system (1) can control the first humidity sensor (120) to detect humidity within the tub (20) of the washing machine (10) (1102). If the humidity within the tub (20) detected by the first humidity sensor (120) is lower than the reference humidity, the first control unit (200) can control the sterilizing device (160) to sterilize the tub (20) and the first drum (30) of the washing machine (10) (1501). Sterilization of the tub (20) and the first drum (30) can be performed for a predetermined sterilization time.

[0223] For example, the sterilizing device (160) may include an ultraviolet light source that irradiates ultraviolet light. The sterilizing device (160) may include at least one of a heater, an infrared lamp, or a UV-LED.

[0224] In addition, the first control unit (200) or the second control unit (400) can control the door driving device (140) to open the first door (13) of the washing machine (10) based on the completion of sterilization (1502). The clothing treatment system (1) can lower the temperature of the tub (20) and improve the drying effect of the tub (20) by automatically opening the first door (13) of the washing machine (10) after removing steam and / or moisture within the tub (20) of the washing machine (10).

[0225] Fig. 16 illustrates a cross-section of a garment handling system according to another embodiment. Fig. 17 illustrates a three-dimensional view of the internal structure of the garment handling system illustrated in Fig. 16. Fig. 18 illustrates a three-dimensional view of the internal structure of the garment handling system illustrated in Fig. 16 from another direction.

[0226] Referring to FIGS. 16, 17, and 18, a clothing treatment system (500) according to another embodiment may be referred to as a 'washing machine with dryer'. The clothing treatment system (500) according to another embodiment includes a housing (501) forming an exterior, a tub (520) for receiving washing water or rinsing water that can be used for a washing cycle or a rinsing cycle, a drum (530) for receiving laundry, and a driving motor (540) for rotating the drum (530). The housing (501) may be formed in a hexahedron.

[0227] An inlet (not shown) may be formed at the front of the housing (501) for loading or unloading laundry into or out of the drum (530). The inlet (not shown) may be opened or closed by a door (502) installed at the front of the housing (501). A user interface for controlling the operation of the garment handling system (500) may be provided at the front upper side of the housing (501).

[0228] A water supply device (590) for supplying washing water to the tub (520) may be placed on the upper portion of the tub (520). The water supply device (590) may be placed at the rear of the drying device (570). The water supply device (590) may include a water supply guide (591) and a water supply valve (not shown). The water supply guide (591) may guide water from the water supply valve (not shown) to the tub (520).

[0229] The clothing treatment system (500) may include a detergent supply device (595) for supplying detergent to the tub (520). A drainage device (593) for discharging washing water used in washing to the outside of the housing (501) is arranged at the bottom of the tub (520).
