In addition, the exhaust and fresh air introduction structures are complex and have a narrow scope of application.

[0044] The present invention creatively provides a clothes processing device, comprising a box body, an outer drum and a drying system; the box body is formed with a box vent, and the outer drum is arranged in the box body; the outer drum is formed with a peripheral wall air outlet and a drying air outlet, and a drying air inlet is formed at the tube mouth of the outer drum; the drying system comprises a main drying air duct, a branch drying air duct, a cooling box and a one-way member, the main drying air duct is connected between the drying air inlet and the drying air outlet; the main drying air duct forms a main vent; the branch drying air duct comprises a first branch air duct section and a second branch air duct section; one end of the first branch air duct section is connected to the peripheral wall air outlet, and one end of the second branch air duct section is connected to the main vent; the second branch air duct section forms a branch vent, and the branch vent is connected to the box vent; the cooling box is connected to the first branch air duct section and the second branch air duct section; the one-way member is arranged in the second branch air duct section and is located downstream of the branch vent;

[0045] When the air pressure in the outer cylinder is lower than the outside air pressure, the outside air can enter the second branch air duct section through the box vents, and then enter the main drying air duct through the one-way component, thereby increasing the flow rate of the drying airflow and improving the quality of the drying airflow; when the air pressure in the outer cylinder is higher than the outside air pressure, the air in the outer cylinder enters the second branch air duct section through the peripheral wall outlet, but cannot be discharged through the one-way component.

[0053] A main vent 2121 is formed on the side wall of the condensing air duct section 212 .

[0054] like Figure 2As shown, in order to solve the problem that the unreasonable structural design of the cooling box 23 leads to insufficient contact of the drying air flow with the condensed water when flowing through the cooling box 23, this embodiment proposes that the cooling box 23 is formed with a cooling chamber 233 and the cooling box 23 includes a first box wall 231 and a second box wall 232 arranged opposite to each other, the first box wall 231 is formed with a cooling box air inlet communicating with the cooling chamber 233, and the second box wall 232 is formed with a cooling box air outlet communicating with the cooling chamber 233, and air can enter the cooling chamber 233 through the cooling box air inlet and be discharged through the cooling box air outlet; a cooling plate 234 is provided in the cooling chamber 233, the cooling plate 234 extends along the length direction of the cooling box 23 and a plurality of cooling plates 234 are provided, and the plurality of cooling plates 234 are arranged at intervals along the width direction of the cooling box 23; a cooling pipe 235 is provided on each cooling plate 234, and the cooling pipe 235 includes a cooling water inlet section 2351 and a cooling water inlet section connected to the cooling water inlet The cooling water outlet section 2352 is connected to the cooling water outlet section 2351; the cooling water inlet section 2351 is located outside the cooling cavity 233 and is formed with a cooling water inlet, the cooling water outlet section 2352 is located inside the cooling cavity 233 and the extension direction of the cooling water outlet section 2352 is consistent with the length direction of the cooling plate 234, the cooling water outlet section 2352 is formed with a cooling water outlet 2353, the cooling water outlet 2353 is formed on the side wall of the cooling water outlet section 2352 and the cooling water outlet 2353 faces the plate surface of the corresponding cooling plate 234, and a plurality of cooling water outlets 2353 are provided, and the plurality of cooling water outlets 2353 are arranged at intervals along the extension direction of the cooling water outlet section 2352; external condensed water can enter the cooling water inlet section 2351 through the cooling water inlet, and then enter the cooling water outlet section 2352, and flow to the plate surface of the corresponding cooling plate 234 through the cooling water outlet 2353, and can be exchanged with the air flowing through the cooling cavity 233.

[0055] In response to the problem that the unreasonable position of the main vent 2121 leads to poor condensation effect and low drying efficiency, this embodiment proposes that the drying air outlet includes a first drying air outlet 112; the condensation air duct section 212 includes a condensation main section 213 and a first condensation branch section 214, the air inlet end of the first condensation branch section 214 is connected to the first drying air outlet 112, the air outlet end of the first condensation branch section 214 is connected to an air inlet end of the condensation main section 213, and the air outlet end of the condensation main section 213 is connected to the drying fan 251; the side wall of the condensation main section 213 forms the main vent 2121, and the main vent 2121 is close to the air inlet end of the condensation main section 213.

[0056] Furthermore, the drying air outlet includes a second drying air outlet 113, which is located above the first drying air outlet 112; the condensing air duct section 212 includes a second condensing branch section 215, the air inlet end of the second condensing branch section 215 is connected to the second drying air outlet 113, and the air outlet end of the second condensing branch section 215 is connected to the other air inlet end of the condensing main section 213;

[0057] An inner water inlet valve is provided on the peripheral wall of the outer cylinder 11. A condensation zone 115 is formed between the inner side surface of the rear wall of the outer cylinder 11 and the inner side surface of the peripheral wall of the outer cylinder 11. Specifically, the condensation zone 115 is formed between the inner side surface of the rear wall of the outer cylinder 11, the inner side surface of the peripheral wall of the outer cylinder 11, and the outer side surface of the rear wall of the inner cylinder 12. The condensation zone 115 is connected to the first drying air outlet 112, the second drying air outlet 113, and the inner water inlet valve. A portion of the drying air flow in the condensation zone 115 enters the first condensation branch section 214 through the first drying air outlet 112, and then enters the main condensation section 213. Condensed water from the outside can enter the condensation zone 115 through the inner water inlet valve. The drying air flow flows from bottom to top along the condensation zone 115 and exchanges heat with the condensed water flowing from top to bottom along the condensation zone 115.

[0058] An external water inlet valve is provided on the side wall of the second condensation branch section 215. The outer side surface of the rear wall of the outer cylinder 11 forms the second condensation branch section 215, and the second condensation branch section 215 is connected to the external water inlet valve. Another part of the drying air flow in the condensation area 115 enters the second condensation branch section 214 through the second drying air outlet 113, and then enters the condensation main section 213. The outer side surface of the rear wall of the outer cylinder 11 forms the second condensation branch section 215, and condensed water from the outside can enter the second condensation branch section 215 through the external water inlet valve. The drying air flow flows from bottom to top along the second condensation branch section 215 and exchanges heat with the condensed water flowing from top to bottom along the second condensation branch section 215.

[0059] The clothing processing device is provided with a drying process.

[0060] The fresh air in the environment where the clothing processing equipment is located can enter the condensation main section 213 through the cabinet vent 131 and the second branch air duct section 222 and mix with the drying air flow. The introduction of fresh air can improve the quality of the drying air flow; the air in the outer cylinder 11 can be discharged through the first branch air duct section 221, the cooling box 23, the second branch air duct section 222, the branch vent 2223 and the cabinet vent 131 to balance the air pressure in the outer cylinder 1111; that is, the introduction of fresh air and the exhaust of air are integrated, which simplifies the structure, expands the scope of application, and improves the condensation effect.

[0061] In order to solve the problem that the structure of the one-way member 26 is complex and cannot realize its function, this embodiment proposes that the one-way member 26 includes an outer shell 261, an inner shell 262 and a sliding core 263. The outer shell 261 forms an outer air duct, and the inner shell 262 is arranged in the outer air duct and forms an inner air duct. The side wall of the inner air duct is formed with a communication port 2621. When the communication port 2621 is opened by the sliding core 263, the inner air duct and the outer air duct are connected. When the communication port 2621 is closed by the sliding core 263, the communication between the inner air duct and the outer air duct is blocked. The sliding core 263 is slidably arranged in the inner air duct.

[0062] The sliding core 263 has an open position and a closed position in its sliding direction. When the sliding core 263 slides along the first direction to the closed position, the sliding core 263 closes the communication port 2621, and the air in the inner air duct cannot enter the outer air duct. When the sliding core 263 slides along the second direction to the open position, the sliding core 263 opens the communication port 2621, and the air in the inner air duct can enter the outer air duct.

[0063] The first direction is opposite to the second direction; when fresh air is introduced, the fresh air is along the second direction, and when the air is exhausted, the air is along the first direction.

[0064] Furthermore, a first end plate 264 and a second end plate 265 are respectively provided at the two axial ends of the housing 261 , and ventilation holes are formed on both the first end plate 264 and the second end plate 265 ; and the following conditions are satisfied: a>b>c;

[0065] Among them, a is the axial distance between the connecting port 2621 and the second end plate 265, c is the axial distance between the connecting port 2621 and the first end plate 264; b is the axial distance between the end of the sliding core 263 close to the connecting port 2621 and the second end plate 265 when the sliding core 263 is in the open position, or the axial distance between the end of the sliding core 263 close to the connecting port 2621 and the first end plate 264 when the sliding core 263 is in the closed position.

[0066] In addition, the second branch air duct section 222 includes an A duct section 2221 and a B duct section 2222. One end of the A duct section 2221 is connected to the condensing main section 213, and one end of the B duct section 2222 is connected to the first drying air outlet 112. One end of the inner air duct is connected to the other end of the A duct section 2221, and one end of the outer air duct is connected to the other end of the B duct section 2222.

[0067] When the air in the outer cylinder 11 flows through the first drying air outlet 112 and enters the B air duct section 2222, the sliding core 263 can slide along the first direction to the closed position; when the outside air flows through the box vent 131 and enters the A air duct section 2221, the sliding core 263 slides along the second direction to the open position.

[0068] like Figures 5a to 6As shown, the drying fan 3 is formed with a blade cavity 33, and the side wall of the blade cavity 33 is further formed with a blade cavity air inlet, a blade cavity air outlet and an opening. The blade cavity air inlet is connected to the air outlet end of the condensing main section 213, and the blade cavity air outlet is connected to the air inlet end of the heating air duct section 211; the opening 311 is connected to the external environment where the drying fan 3 is located, and the opening 311 is used to introduce fresh air from the external environment into the blade cavity 33; the fresh air in the box 13 or the fresh air in the environment where the clothes processing device is located can enter the blade cavity 33 through the opening 311 and mix with the drying air flow. The introduction of fresh air can improve the quality of the drying air flow;

[0069] When the fresh air enters the fan blade cavity 33 through the opening 311, a portion of the dry air flow in the outer tube 11 can be discharged through the first branch air duct section 221, the cooling box 23, the second branch air duct section 222, the branch vent 2223 and the box vent 131 to balance the air pressure in the outer tube 11. At the same time, the dry air flow can circulate in the first dry air flow loop.

[0070] To address the problem of high resistance to fresh air introduction due to an unreasonable position of the opening 311, this embodiment proposes that the drying fan 3 is a centrifugal fan; an axial side wall of the blade cavity 33 is formed with a blade cavity air inlet, and another axial side wall of the blade cavity 33 is formed with an opening 311; and a radial side wall of the blade cavity 33 is formed with a blade cavity air outlet.

[0071] The fresh air and the drying air flow enter the air blade cavity 33 from different directions and are fully mixed, thereby reducing the humidity of the drying air flow and increasing the flow rate of the drying air flow.

[0072] In response to the problem of insufficient flow of introduced fresh air, this embodiment proposes that the fan blades include a first fan blade 341 and a second fan blade 342 rotatably arranged in the fan blade cavity 33, and the first fan blade 341 and the second fan blade 342 are arranged side by side and coaxially along the axial direction of the fan blade cavity 33; the first fan blade 341 and the second fan blade 342 rotate synchronously, and the first fan blade 341 is close to the opening 311 relative to the second fan blade 342. The first fan blade 341 rotates to allow fresh air to enter the fan blade cavity 33 through the opening 311; the second fan blade 342 is close to the air inlet of the fan blade cavity relative to the first fan blade 341. The second fan blade 342 rotates to allow dry airflow to enter the fan blade cavity 33; the fresh air and the dry airflow are mixed in the fan blade cavity 33.

[0073] To address the issue of the mutual influence between the fresh air and the drying airflow when the first fan blade 341 and the second fan blade 342 rotate synchronously, this embodiment proposes that the drying fan 3 further includes a partition 37, which includes a support portion 371 and a partition portion 372; the support portion 371 is provided between the first fan blade 341 and the second fan blade 342, and the partition portion 372 is provided on the support portion 371;

[0074] The partition 372 has a curved structure and protrudes toward the side of the second fan blade 342 away from the first fan blade 341. The partition 372 separates the inner side of the first fan blade 341 from the inner side of the second fan blade 342, ensuring that the flow rate of the fresh air is smaller than the flow rate of the drying air flow, thereby preventing the introduced fresh air from having a significant impact on the drying air flow.

[0075] Preferably, the support portion 371 is an annular plate structure, and the partition portion 372 is a hemispherical shell structure.

[0076] To address the problem that the fan motor occupies a large space, the present embodiment proposes that the drying fan 3 includes a first volute 31, a second volute 32 and a fan motor 35. The first volute 31 and the second volute 32 are buckled together to form a fan chamber 33. An opening 311 is formed on the side wall of the first volute 31 away from the second volute 32, and a motor bracket 36 is provided at the opening 311. Specifically, a plurality of motor brackets 36 are provided, each motor bracket 36 includes a supporting section and a connecting section. The supporting section is connected to the first volute 31, and the connecting section extends radially along the fan chamber 33 and is connected to the supporting section. The plurality of motor brackets 36 are arranged at intervals along the circumference of the fan chamber 33, and the ends of the plurality of connecting sections away from the supporting sections are surrounded by a mounting frame.

[0077] The partition portion 372 is surrounded by a partition cavity 373. The partition cavity 373 has an axial hole formed on the side wall away from the first fan blade 341. The fan motor 35 includes a motor body 351 and an output shaft 352. One axial end of the motor body 351 is mounted on the motor bracket 36, and the other axial end of the motor body 351 passes through the inner side of the first fan blade 341 and enters the partition cavity 373. The output shaft 352 passes through the axial hole and is drivingly connected to the partition portion 372. The support portion 371 connects the first fan blade 341 and the second fan blade 342. When the output shaft 352 rotates, the partition portion 372 drives the support portion 371 to rotate, and the support portion 371 then drives the first fan blade 341 and the second fan blade 342 to rotate.

[0078] There are gaps between the side walls of the opening 311 and the motor body 351, and between the blades of the first fan blade 341 and the motor body 351; fresh air can enter the fan chamber 33 through the gaps; in this way, the setting of the opening 311 does not affect the setting of the fan motor 35, and the fan motor 35 occupies a small space outside the fan chamber 33, and has a wide range of applications.

[0079] The end of the opening 311 away from the fan chamber 33 is a flared structure, that is, the inner diameter of the opening 311 gradually increases from inside to outside along the axial direction of the fan chamber 33, so as to allow more fresh air to enter the fan chamber 33 through the opening 311.

[0080] While the exemplary embodiments of the present disclosure have been specifically illustrated and described above, it should be understood that the present disclosure is not limited to the detailed structures, configurations, or implementations described herein; rather, the present disclosure is intended to encompass various modifications and equivalent configurations within the spirit and scope of the appended claims.
