Under the action of the fan 32, the airflow can circulate in the drying air duct and the drum module 2, and exchange heat with the evaporator 34 and the condenser 35 when flowing through the evaporator 34 and the condenser 35.

[0046] Preferably, if Figures 1 to 3 As shown, the drying air duct of the utility model includes a first drying air duct 31 and a second drying air duct 33.

The compressor, evaporator 34 and condenser 35 are connected to each other to form a refrigerant circulation loop. The refrigerant exchanges heat with the hot and humid air flowing through the evaporator 34, which can condense the moisture in the hot and humid air and separate it from the airflow. The refrigerant exchanges heat with the air flowing through the condenser 35, which can increase the temperature of the air, thereby supplying hot air to the barrel module 2.

[0054] Preferably, if Figures 1 to 3As shown, the first drying air duct 31 includes a return air duct 311 and a first heat exchange air duct 312 which are connected.

The second heat exchange air duct 331 also extends in the horizontal direction, and the extension direction of the second heat exchange air duct 331 is parallel to the axial direction of the barrel module 2, that is, the extension direction of the second heat exchange air duct 331 is perpendicular to the extension direction of the first heat exchange air duct 312, and the two heat exchange air ducts are arranged in an approximately L shape.

[0057] The second heat exchange air duct 331 and the air outlet air duct 332 are preferably configured to be detachably fixedly connected.

[0058] It should be noted that the front end of the drum module 2 has a clothing access port, and those skilled in the art may use the clothing access port as an air inlet, even if the air outlet duct 332 is connected to the clothing access port, or, a separate air port may be opened above the front end of the drum module 2 as an air inlet, and so on.

[0071] The diverter plate is disposed in the plug-in tube 335 , extending along the flow direction of the airflow, from one end of the plug-in tube 335 to the other end. In addition to playing the role of diversion, it can also play a supporting role to improve the rigidity of the plug-in tube 335 .

[0072] Preferably, if Figure 4 and Figure 5 As shown, there are multiple diverter plates, and the multiple diverter plates are distributed at intervals along the length direction of the air outlet port.

[0073] Exemplarily, the plug-in tube 335 is flat, and two diverter plates are disposed inside the plug-in tube 335 . The two diverter plates are spaced apart along the length direction of the air outlet port, dividing the air outlet port into three outlets.

[0093] The filter is used to filter the air flow in the first drying air duct 31 and intercept impurities such as lint carried by the air flow. By providing plug interfaces on the box body 1 and the first drying air duct 31, when the filter device 4 needs to be cleaned, the filter component can be pulled out from the first drying air duct 31 and the box body 1. In addition, by setting the first bracket 41 and the second bracket 42 to be detachably connected, after the first bracket 41 is pulled out, the first bracket 41 and the second bracket 42 are disassembled, and then the second bracket 42 is pulled out, the required disassembly space can be reduced, which is convenient for users to disassemble and also convenient for cleaning the filter on the second bracket 42. In addition, by making the two ends of the outer shell 43 connected to the first plug interface 3121 and the second plug interface 11 respectively, when installing the filter component, it is convenient to smoothly insert the filter component into the first drying air duct 31, and the user experience is better.

When the locking pin 44 is in the unlocked position, the first locking structure 441 is separated from the second locking structure 4221 so as to disassemble and separate the second bracket 42 from the first bracket 41.

[0096] Exemplarily, a vertically extending accommodating cavity (not shown in the figure) is provided on the first bracket 41, and the top of the accommodating cavity is open. The locking pin 44 is installed in the accommodating cavity and can move up and down in the vertical direction to switch between the locked position and the unlocked position. The first locking structure 441 includes two locking hooks, and the two locking hooks are spaced apart in the vertical direction. The second locking structure 4221 includes two locking holes arranged at the end of the second bracket 42, and the locking holes are adapted to the locking hooks. A reset spring (not shown in the figure) is installed between the bottom of the locking pin 44 and the accommodating cavity. Under the action of the reset spring, the two locking hooks are respectively inserted into the corresponding locking holes to lock the first bracket 41 and the second bracket 42. When the two brackets need to be disassembled, the locking pin 44 is pressed downward to separate the locking hook from the locking hole, so that the first bracket 41 and the second bracket 42 can be disassembled.

[0097] It should be noted that the first locking structure 441 and the second locking structure 4221 are not limited to the structure of the lock hook and the lock hole described above. For example, they can also be set as two opposite lock hooks, etc. Such adjustments and changes to the specific structural forms of the first locking structure 441 and the second locking structure 4221 do not deviate from the principle and scope of the present utility model, and should be limited within the protection scope of the present utility model.

The filter includes a first filter installed on the first filter frame 421 and a second filter installed on the second filter frame 422. The mesh number of the first filter is greater than the mesh number of the second filter, and the first filter is located downstream of the second filter.

[0099] Among them, the first filter frame 421 and the second filter frame 422 are arranged side by side along the flow direction of the airflow, the first filter frame 421 is located downstream of the second filter frame 422, the second filter and the first filter are arranged in sequence along the flow direction of the airflow, the airflow first flows through the second filter for coarse filtration, and then flows through the first filter for fine filtration, the filtering effect is better, in addition, by pivotally connecting the first filter frame 421 with the second filter frame 422, it is convenient to clean the first filter and the second filter.

[0100] For example, Figure 8 and Fig. 9 As shown, the second locking structure 4221 is arranged at the first end of the second filter frame 422, and the end face of the first bracket 41 close to the second bracket 42 has a socket (not shown in the figure), the first end of the second filter frame 422 passes through the socket and extends into the first bracket 41, the second end of the first filter frame 421 does not pass through the socket, and the second end of the first filter frame 421 is located on the outside of the first bracket 41, that is, the length of the first filter frame 421 is less than the length of the second filter frame 422.

[0101] It should be noted that, in actual applications, those skilled in the art may also make the first end of the first filter frame 421 detachably fixedly connected to the first bracket 41, or make the first ends of the first filter frame 421 and the second filter frame 422 detachably fixedly connected to the second end of the first bracket 41.

[0102] In addition, it should be noted that, in actual applications, those skilled in the art may also cancel the setting of the outer shell 43, or may also cancel the setting of the first bracket 41. In this case, the second bracket 42 and the filter can be inserted into the drying air duct from the back or top surface of the box body 1. Alternatively, the first bracket 41 and the second bracket 42 may be completely canceled. In this case, the filter can be directly fixed in the drying air duct, etc. These sub-preferred implementations are also within the protection scope of the present utility model.

[0104] Among them, the elastic sealing component 45 is arranged at the second end of the second bracket 42 of the filtering device 4, and the elastic sealing component 45 is against the inner wall of the first drying air duct 31, which can seal the gap between the end of the second bracket 42 and the first inner wall to prevent the wire scraps carried by the airflow from passing through, thereby improving the filtering effect.

[0105] Exemplarily, a receiving groove is provided at the second end of the second bracket 42 , and a portion of the elastic sealing member 45 is embedded in the receiving groove, so that the elastic sealing member 45 is fixed to the second bracket 42 .

[0106] Of course, those skilled in the art can also set the elastic sealing member 45 and the second bracket 42 in one piece in actual application. Specifically, the second bracket 42 of the filter device is generally made of plastic material, and the elastic sealing member 45 is made of rubber material, and double injection molding can be performed to directly integrate the elastic sealing member 45 and the second bracket 42 into one piece.

[0107] Preferably, if Figures 6 to 8 As shown, the elastic sealing component 45 of the utility model includes a main body portion and a supporting portion which are connected to each other.
