[0070] The second laundry treating device 60 may include a second drum 70 configured to accommodate articles. The second drum 70 may be disposed inside the second housing 61 so that a second drum opening 72 disposed on one side thereof corresponds to the article inlet 62. Articles may be accommodated in or taken out of the second drum 70 sequentially through the article inlet 62 and the second drum opening 72. The second drum 70 may be rotatably disposed inside the second housing 61.

[0071] The second laundry treating apparatus 60 may include a second driving device 73 configured to rotate the second drum 70. The second driving device 73 may include a second driving motor and a second rotating shaft configured to transmit a driving force generated by the second driving motor to the second drum 70.

[0072] The second drum 70 may include an air inlet 71 through which air is introduced into the second drum 70. The air inside the second drum 70 may be discharged to the outside of the second drum 70 through the second drum opening 72. The air inlet 71 may be positioned at a side of the second drum 70 opposite to a side where the second drum opening 72 is positioned. For example, the air inlet 71 may be positioned at the rear of the second drum 70, and the second drum opening 72 may be positioned at the front of the second drum 70.

[0073] High-temperature dry air may be introduced into the second drum 70 through the air inlet 71 to dry the items contained in the second drum 70. The air containing a large amount of moisture after drying the items may be discharged from the second drum 70 through the second drum opening 72.

[0074] At least one second lifter 74 may be provided inside the second drum 70. The second lifter 74 may raise and lower the objects so that the objects come into contact with the hot air while floating in the inner space of the second drum 70.

[0075] Inside the second housing 61, a heat pump 80 may be provided, which is configured to heat the air and condense the air. An evaporator 81, a condenser 82, a compressor 83, an expansion device, etc. constituting the heat pump 80 may be provided below the second roller 70. The refrigerant may be circulated by a series of processes leading to compression-condensation-expansion-evaporation. Specifically, the heat pump 80 may include an evaporator 81, a condenser 82, a compressor 83, and an expansion device. The evaporator 81 and the condenser 82 may exchange heat with the air.

[0076] The compressor 83 compresses and discharges the refrigerant in a high-temperature and high-pressure state, and the discharged refrigerant may be introduced into the condenser 82. The condenser 82 may condense the compressed refrigerant and dissipate heat to the surroundings through a condensation process. The expansion device may expand the high-temperature and high-pressure refrigerant condensed in the condenser 82 to a low-pressure state. The evaporator 81 may evaporate the expanded refrigerant through an evaporation process and absorb heat from the surrounding environment.

[0077] As the operating RPM of the compressor 83 increases, the amount of heat radiated to the surroundings through the condensation process of the condenser 82 may increase.

[0078] When the articles are placed in the second laundry treatment device 60 and operated in the drying mode, the high temperature and high humidity air discharged from the second drum 70 may pass through the evaporator 81. Accordingly, the high temperature and high humidity air discharged from the second drum 70 may be cooled when passing through the evaporator 81, thereby changing to low temperature dry air. At this time, since the high temperature and high humidity air is cooled in the evaporator 81, condensed water may be generated. The condensed water may be moved to the water recovery container or discharged to the outside of the second housing 61. The air in a low temperature dry state after passing through the evaporator 81 may pass through the condenser 82. Accordingly, the low temperature dry air discharged from the evaporator 81 may be heated when passing through the condenser 82, thereby changing to high temperature dry air. The high temperature dry air may be introduced into the second drum 70 through the air inlet 71 to dry the articles. When drying the articles, the high temperature and high humidity air containing a large amount of moisture may be discharged through the second drum opening 72. The discharged air may pass through the evaporator 81 again. In summary, the articles contained in the second drum 70 may be dried when the air circulates in the second housing 61.

[0079] In the drying mode, a closed flow path may be formed inside the second housing 61 of the second laundry treating device 60. The closed flow path may be an air moving path (refer to Figure 5), the air movement path is formed to circulate air inside the second shell 61 through the heat pump 80 and the second drum 70. The closed flow path may not be connected to the outside of the second shell 61, so that the air outside the second shell 61 does not flow in or out. That is, the flow of air can form a closed loop.

[0080] The second laundry treatment device 60 may include a heater 86 disposed in a closed flow path. The heater 86 may be implemented by a heating coil, but is not limited thereto, and may be implemented by various known devices. The heater 86 may also heat the air heated when passing through the condenser 82, or heat the air sucked from the outside without being heated by the heat pump 80.

[0081] refer to Figure 4 , the second laundry treatment device 60 may include a housing opening 69 provided on the front surface of the second housing 61 to access the heat pump 80. The filter device 96 may be installed inside the second housing 61 through the housing opening 69. Specifically, the filter device 96 may be detachably installed on a device receiving member 68 formed inside the second housing 61 through the housing opening 69. When the filter device 96 is installed on the receiving member 68, the second laundry treatment device 60 may perform a drying mode (drying operation) for drying items such as laundry. In addition, a housing cover 67 may be provided on the front surface of the second housing 61 for opening and closing the housing opening 69.

[0082] In a state where the housing cover 67 closes the housing opening 69, since the front surface of the housing cover 67 is connected to the front surface of the second housing 61, a surface without steps and smoothly connected is formed. When the filter device 96 is not installed inside the second housing 61, the user can access the heat pump 80 through the housing opening 69. When the dryer is used for a long time, foreign matter such as lint may adhere to the heat exchanger, and the user can remove these foreign matter through the housing opening 69.

[0083] The filter device 96 may be detachably mounted on the second laundry treating apparatus 60. Specifically, the filter device 96 may be detachably mounted inside the second housing 61 through the housing opening 69. The filter device 96 may be mounted on the device receiving member 68, or may be separated from the device receiving member 68.

[0084] The fan 90 may be disposed below the second drum 70. 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.

The leg 140 may pass through the protrusion 132 and then be fixedly seated on the seating portion 133 by the protrusion 132 and the stopper 134. Since one side of the leg 140 is supported by the protrusion 132 and the other side of the leg 140 is supported by the stopper 134, the leg 140 may be fixedly seated on the seating portion 133. In the process of the leg 140 being seated on the seating portion 133 after passing through the protrusion 132, the contact between the leg 140 and the stopper 134 may generate a sound. Through the sound, the user can confirm that the leg 140 is seated on the seating portion 133. Since the user can intuitively know whether the leg 140 is seated through the sound, the convenience can be improved.

[0240] refer to Fig.14 , the leg 140 may include: a fastening portion 141, which is configured to be fastened to a leg hole 151 to be described later, and the leg hole 151 is formed on the lower surface 150 of the second shell 61; and a flange portion 142, which is provided at the lower end of the fastening portion 141.

The lower surface 143 of the flange portion 142 may refer to the lower surface 143 of the leg 140.

[0241] like Fig.14As shown, in the laundry processing system 1 according to the present disclosure, the lower surface 143 of the leg 140 placed on the leg placement portion 131 may not be in contact with the placement portion 133. A predetermined gap g may be formed between the lower surface 143 of the leg 140 placed on the leg placement portion 131 and the placement portion 133. When the leg 140 is placed on the leg placement portion 131, in a case where the lower surface 143 of the leg 140 is in contact with the placement portion 133, the load of the second laundry processing device 60 transmitted through the leg 140 may be concentrated on the placement portion 133. When the load of the second laundry processing device 60 is concentrated on the placement portion 133, the placement portion 133 may be damaged. According to the present disclosure, in order to prevent the load from being concentrated on the placement portion 133 and to disperse the load, a predetermined gap g may be formed between the lower surface 143 of the leg 140 and the placement portion 133.

[0242] According to the present disclosure, the lower surface 143 of the leg 140 seated on the leg seating portion 131 may be located below the upper surface 110 of the first laundry treating device 10. Fig.14 As shown, the lower surface 143 of the leg 140 can be located below a surface 110a of the upper surface 110. Thereby, the height of the clothing treatment system 1 according to the present disclosure can be reduced, and the height of the article inlet 62 of the second clothing treatment device 60 can be reduced. In the case of a relatively short woman, the use of the clothing treatment system 1 may be inconvenient because the article inlet 62 of the second clothing treatment device 60 is high. Conventionally, after a separate structure is coupled to the first clothing treatment device, the second clothing treatment device is positioned on the separate structure and coupled to the separate structure. That is, since a separate structure is provided between the first clothing treatment device and the second clothing treatment device, not only the overall height of the clothing treatment system is increased, but also the height of the article inlet of the second clothing treatment device is increased. In the laundry treatment system 1 according to the present disclosure, since not only a separate structure for combining the first laundry treatment device 10 and the second laundry treatment device 60 is not provided between the first laundry treatment device 10 and the second laundry treatment device 60, but also the lower surface 143 of the leg 140 provided on the lower surface of the second laundry treatment device 60 is located below the upper surface 110 of the first laundry treatment device 10, the overall height of the laundry treatment system 1 can be reduced. In addition, the height of the article inlet 62 of the second laundry treatment device 60 can be reduced. Therefore, the convenience of the user can be improved, the space utilization can be improved due to the reduction in the height of the laundry treatment system, and since the first laundry treatment device and the second laundry treatment device do not require a separate structure when coupled, the number of components and the number of processes can be reduced and the combination can be facilitated.
