[0002] For clothing processing equipment using water-cooled drying, the drying system includes a condenser duct and a heating duct. The hot and humid drying airflow enters the condenser duct and comes into direct or indirect contact with the condensate water to complete heat exchange, thus transforming into a dry and cool drying airflow.

[0042] In the existing technology, the drying airflow inside the outer cylinder is dehumidified before being discharged into the room to reduce the impact of the drying airflow on the indoor air; however, the required condensation device has a complex structure and an unreasonable structural design, which fails to make full use of the condensate discharged from the outer cylinder, resulting in high energy consumption and a narrow range of applications in the drying process;

[0043] This invention creatively provides a garment processing device, including a housing, an outer cylinder, and a condenser assembly. The outer cylinder is disposed within the housing and has an outer cylinder exhaust port and an outer cylinder drain port. The condenser assembly includes a condenser box, a condenser box air inlet pipe, a first condenser box water inlet pipe, and a spray pipe. A condensation chamber is formed inside the condenser box, and the side wall of the condenser box has a condenser box air inlet, a condenser box exhaust port, and a condenser box mounting port. The condenser box exhaust port communicates with the outside of the housing, allowing air from the condensation chamber to be exhausted to the outside of the housing. The condenser box air inlet pipe is connected to the outside... The system includes a cylinder exhaust vent and a condenser box inlet; the first condenser box water inlet pipe connects to the outer cylinder drain outlet and the spray pipe; the spray pipe is installed at the condenser box mounting port, with its outlet located inside the condensation chamber; air inside the outer cylinder can enter the condensation chamber through the condenser box inlet pipe, and condensate inside the outer cylinder can enter the spray pipe through the first condenser box water inlet pipe, then be sprayed into the condensation chamber and exchange heat with the flowing air; the condenser box assembly has a simple structure, fully utilizes the condensate discharged from the outer cylinder to dehumidify the air discharged from the outer cylinder, reduces energy consumption in the drying process, and has a wide range of applications.

[0044] <Clothing Processing Equipment>

[0045] like Figure 1 and Figure 2As shown, this embodiment provides a garment processing device, including a housing 13, an outer cylinder 11, and a condenser assembly; the outer cylinder 11 is disposed inside the housing 13 and has an outer cylinder exhaust port 111 and an outer cylinder drain port 112; specifically, the outer cylinder 11 includes an outer cylinder peripheral wall, with an outer cylinder exhaust port 111 formed on the upper side of the outer cylinder peripheral wall and an outer cylinder drain port 112 formed on the lower side of the outer cylinder peripheral wall; the condenser assembly includes:

[0046] A condenser box 2 is mounted on the housing 13 and has a condensation chamber 21 inside. The side wall of the condenser box 2 has a condenser box air inlet 22, a condenser box air outlet 23, and a condenser box mounting port that communicate with the condensation chamber 21. The condenser box air outlet 23 communicates with the outside of the housing 13 and can exhaust the air in the condensation chamber 21 to the outside of the housing 13. Specifically, the condenser box 2 is mounted on the back panel of the housing 13.

[0047] The condenser box air inlet pipe 3 connects the outer cylinder exhaust port 111 and the condenser box air inlet port 22; the condenser box air inlet pipe 3 can input the air in the outer cylinder 11 into the condensation chamber 21; specifically, a first temperature sensor is installed in the condenser box air inlet pipe 3 to detect the temperature of the air in the condenser box air inlet pipe 3.

[0048] The first condenser box has a water inlet pipe 32 and a spray pipe 34. The inlet end of the first condenser box water inlet pipe 32 is connected to the outer cylinder drain outlet 112 via a water pump, and the outlet end of the first condenser box water inlet pipe 32 is connected to the inlet end of the spray pipe 34. Under the action of the water pump, the first condenser box water inlet pipe 32 can transport the condensate in the outer cylinder 11 to the spray pipe 34. The spray pipe 34 is located at the condenser box installation port, and the outlet end of the spray pipe 34 is located inside the condensation chamber 21. The spray pipe 34 can spray the condensate inside the spray pipe 34 onto the condenser box. The condensation chamber 21 exchanges heat with the air flowing through it, maximizing the use of the energy of the condensate and reducing energy consumption during the drying process. During the drying process, if the air pressure inside the outer cylinder 11 is too high, the drying airflow inside the outer cylinder 11 can be quickly discharged to the outside, avoiding high temperature and condensation in the water box, achieving air pressure balance while improving drying efficiency. Specifically, a second temperature sensor is installed inside the first condensation box water inlet pipe 32 to detect the temperature of the condensate inside the first condensation box water inlet pipe 32.

[0049] Furthermore, the outer cylinder 11 also has an outer cylinder water inlet 113; the side wall of the condenser box 2 also has a condenser box drain outlet 24 that communicates with the condenser chamber 21; the condenser box assembly also includes a condenser box drain pipe 33, which connects the condenser box drain outlet 24 and the outer cylinder water inlet 113. The condenser box drain pipe 33 can transport the condensed water in the condenser chamber 21 to the outer cylinder 11; in this way, the condensed water in the outer cylinder 11 can enter the condenser chamber 21 through the first condenser box water inlet pipe 32 and the spray pipe 34, and then enter the outer cylinder 11 again through the condenser box drain pipe 33, realizing the recycling of condensed water, improving the utilization rate of condensed water, and reducing energy consumption during the drying process.

[0050] To address the issue of poor condensation performance caused by an unreasonable structural design of the condenser box 2, this embodiment proposes that the condenser box 2 includes a first condenser box sidewall, a second condenser box sidewall, and a condenser box bottom wall arranged opposite to each other. The first condenser box sidewall is located away from the housing 13 and has a condenser box air inlet 22 and a condenser box mounting port, with the air inlet 22 located below the mounting port. The second condenser box sidewall is located close to the housing 13 and has a condenser box exhaust port 23, which is positioned higher than the air inlet 22. The bottom wall connects the first and second condenser box sidewalls and has a condenser box drain outlet 24. Thus, air enters the condensation chamber 21 through the condenser box air inlet 22, flows upward, and is discharged through the condenser box exhaust port 23. Condensed water is sprayed out through the outlet of the spray pipe 34, flows downward, and is discharged through the condenser box drain outlet 24.

[0051] To address the issue of low heat exchange efficiency between air and condensate in the condensation chamber 21, this embodiment proposes that multiple condensation plates 35 are provided inside the condensation box 2, each condensation plate 35 being corrugated; the multiple condensation plates 35 are arranged sequentially at intervals from the side wall of the first condensation box to the side wall of the second condensation box; the condensate flowing out from the outlet end of the spray pipe 34 can flow along the multiple condensation plates 35 and exchange heat with the air flowing through the multiple condensation plates 35; this slows down the flow rate of the condensate, increases the heat exchange area between air and condensate, prolongs the heat exchange time between air and condensate, and improves the heat exchange efficiency between air and condensate.

[0052] Furthermore, the condenser assembly also includes a three-way pipe 36, which includes a first water inlet, a second water inlet, and a third water inlet. The first water inlet is connected to the outlet of the first condenser inlet pipe 32 via a first water inlet valve. The second water inlet is connected to the inlet pipe of the second condenser 2 via a second water inlet valve. The third water inlet is connected to the inlet of the spray pipe 34. By controlling the first water inlet valve to open and the second water inlet valve to close, the condensate in the outer cylinder 11 can enter the spray pipe 34 through the first condenser inlet pipe 32, making full use of the condensate discharged from the outer cylinder 11 to dehumidify the air discharged from the outer cylinder 11, thus preventing the air discharged from the outer cylinder 11 from affecting the comfort of the indoor air. By controlling the second water inlet valve to open and the first water inlet valve to close, the condensate in the outside can enter the spray pipe 34 through the second condenser inlet pipe 2 to dehumidify the air discharged from the outer cylinder 11, thus avoiding the problem that the condensate discharged from the outer cylinder 11 is too hot to dehumidify.

[0053] In addition, a drying air inlet 114 is formed at the opening of the outer cylinder 11, and the cylinder wall of the outer cylinder 11 includes a rear wall, which forms a drying air outlet. Specifically, a door seal is provided at the opening of the outer cylinder 11, and the door seal forms the drying air inlet 114. The clothing processing equipment also includes a drying air duct and an inner cylinder 12. The drying air duct includes a heating air duct section 41 and a condensing air duct section. One end of the heating air duct section 41 is connected to the drying air inlet 114, and one end of the condensing air duct section is connected to the drying air outlet. The other end of the heating air duct section 41 and the other end of the condensing air duct section are connected through a drying fan 5. The inner cylinder 12 is rotatably disposed inside the outer cylinder 11 and is used to hold clothing. Thus, the outer cylinder 11, the inner cylinder 12, the condensing air duct section, the drying fan 5, and the heating air duct section 41 form a drying airflow circuit. Under the action of the drying fan 5, the drying airflow circulates in the drying airflow circuit to dry the clothing inside the inner cylinder 12.

[0054] To address the issue of poor dehumidification in the condenser duct section, this embodiment proposes that the drying air outlet includes a first drying air outlet 115 and a second drying air outlet 116, with the first drying air outlet 115 located above the second drying air outlet 116; the drying fan 5 has a fan blade cavity, which contains a first drying fan inlet and a second drying fan inlet; the condenser duct section includes a first condenser duct section and a second condenser duct section, with the first condenser duct section connecting the first drying air outlet 115 and the first drying fan inlet, and the second condenser duct section connecting the second drying air outlet 116 and the second drying fan inlet;

[0055] An inner water inlet valve is provided on the outer cylinder peripheral wall. A condensation zone 117 is formed between the inner side of the outer cylinder rear wall and the inner side of the outer cylinder peripheral wall. Specifically, a condensation zone 117 is formed between the inner side of the outer cylinder rear wall, the inner side of the outer cylinder peripheral wall, and the outer side of the rear wall of the inner cylinder 12. The condensation zone 117 is connected to the first drying air outlet 115, the second drying air outlet 116, and the inner water inlet valve. A portion of the drying airflow in the condensation zone 117 enters the first condensation air duct section 421 through the first drying air outlet 115. External condensate can enter the condensation zone 117 through the inner water inlet valve. The drying airflow flows from bottom to top along the condensation zone 117 and exchanges heat with the condensate flowing from top to bottom along the condensation zone 117, and then enters the first condensation air duct section 421 through the first drying air outlet 115.

[0056] An external water inlet valve is provided on the side wall of the second condensing air duct section 422. The outer side of the rear wall of the outer cylinder forms the second condensing air duct section 422, which is connected to the external water inlet valve. Another part of the drying airflow in the condensing zone 117 enters the second condensing air duct section 422 through the second drying air outlet 113. The external condensed water can enter the second condensing air duct section 422 through the external water inlet valve. The drying airflow flows from bottom to top along the second condensing air duct section 422 and exchanges heat with the condensed water flowing from top to bottom along the second condensing air duct section 422.

[0057] The garment processing equipment is equipped with a drying process. When the drying process is running, the drying airflow enters the outer drum 11 through the drying air inlet 114, and then enters the inner drum 12 to exchange heat with the clothes inside the inner drum 12. Part of the drying airflow enters the first condensing air duct section 421 through the first drying air outlet 115, and another part of the drying airflow enters the second condensing air duct section 422 through the second drying air outlet 113. Under the action of the drying fan 5, it enters the heating air duct section 41. After being heated by the heating element, the drying airflow enters the outer drum 11 through the drying air inlet 114. While ensuring that the required condensate water is kept low, the drying effect is improved, the utilization rate of condensate water is increased, and water and energy are saved. The load on the drying fan 5 is reduced, and the accumulation of moisture in the drying airflow is avoided.

[0058] like Figures 4a to 5 As shown, the sidewall of the fan blade cavity 53 also forms a first drying fan inlet, a second drying fan inlet, a fan blade cavity outlet, and an opening. The first drying fan inlet is connected to the outlet of the first condenser duct section 421, and the second drying fan inlet is connected to the outlet of the second condenser duct section 422. The fan blade cavity outlet is connected to the inlet of the heating duct section 41. The opening 511 is connected to the external environment where the drying fan 5 is located. The opening 511 is used to introduce fresh air from the external environment into the fan blade cavity 53. Fresh air in the housing 13 or fresh air from the environment where the clothing processing equipment is located can enter the fan blade cavity 53 through the opening 511 and mix with the drying airflow. Introducing fresh air can improve the quality of the drying airflow.

[0059] When fresh air enters the fan blade cavity 53 through the opening 511, a portion of the drying airflow inside the outer cylinder 11 can be discharged to the outside of the housing 13 through the condenser box inlet pipe 31, the condenser box 2, and the condenser box exhaust port 23 to balance the air pressure inside the outer cylinder 11. At the same time, the drying airflow can circulate in the drying airflow circuit.

[0060] To address the issue of high resistance to fresh air intake caused by the unreasonable placement of the opening 511, this embodiment proposes that the drying fan 5 is a centrifugal fan; a first air inlet and a second air inlet are formed on one axial sidewall of the fan blade cavity 53, and an opening 511 is formed on the other axial sidewall of the fan blade cavity 53; an air outlet is formed on the radial sidewall of the fan blade cavity 53.

[0061] Fresh air and drying airflow enter the fan blade cavity 53 from different directions and mix thoroughly, reducing the humidity of the drying airflow and increasing its flow rate.

[0062] To address the issue of insufficient fresh air flow, this embodiment proposes that the fan blades include a first fan blade 541 and a second fan blade 542 rotatably disposed within the fan blade cavity 53. The first fan blade 541 and the second fan blade 542 are arranged side by side and coaxially along the axial direction of the fan blade cavity 53. The first fan blade 541 and the second fan blade 542 rotate synchronously, with the first fan blade 541 being closer to the opening 511 relative to the second fan blade 542. The rotation of the first fan blade 541 allows fresh air to enter the fan blade cavity 53 through the opening 511. The second fan blade 542 is closer to the air inlet of the fan blade cavity relative to the first fan blade 541. The rotation of the second fan blade 542 allows the drying airflow to enter the fan blade cavity 53. The fresh air and the drying airflow mix within the fan blade cavity 53.

[0063] To address the issue of mutual interference between fresh air and drying airflow when the first fan blade 541 and the second fan blade 542 rotate synchronously, this embodiment proposes that the drying fan 5 further includes a separator 57, which includes a support portion 571 and a separator portion 572; the support portion 571 is disposed between the first fan blade 541 and the second fan blade 542, and the separator portion 572 is disposed on the support portion 571.

[0064] The partition 572 has a curved structure and protrudes towards the side of the second fan blade 542 away from the first fan blade 541; the partition 572 separates the inner side of the first fan blade 541 and the inner side of the second fan blade 542 to ensure that the flow rate of fresh air is less than the flow rate of the drying airflow and to avoid the introduced fresh air having a significant impact on the drying airflow.

[0065] Preferably, the support portion 571 is an annular plate structure and the partition portion 572 is a hemispherical shell structure.

[0066] To address the issue of the large space occupied by the fan motor, this embodiment proposes that the drying fan 5 includes a first volute 51, a second volute 52, and a fan motor 55. The first volute 51 and the second volute 52 are fastened together to form a fan cavity 53. An opening 511 is formed on the side wall of the first volute 51 away from the second volute 52, and a motor bracket 56 is provided at the opening 511. Specifically, multiple motor brackets 56 are provided, each motor bracket 56 including a support section and a connecting section. The support section is connected to the first volute 51, and the connecting section extends radially along the fan cavity 53 and is connected to the support section. Multiple motor brackets 56 are arranged at intervals along the circumference of the fan cavity 53, and the ends of multiple connecting sections away from the support sections are surrounded by an installation frame.

[0067] The partition 572 is configured to form a partition cavity 573, and the side wall of the partition cavity 573 away from the first fan blade 541 has a shaft hole; the fan motor 55 includes a motor body 551 and an output shaft 552, one end of the motor body 551 is mounted on the motor bracket 56, and the other end of the motor body 551 passes through the inner side of the first fan blade 541 and enters the partition cavity 573; the output shaft 552 passes through the shaft hole and is drivenly connected to the partition 572; the support part 571 connects the first fan blade 541 and the second fan blade 542. When the output shaft 552 rotates, the partition 572 drives the support part 571 to rotate, and then the support part 571 drives the first fan blade 541 and the second fan blade 542 to rotate;

[0068] There are gaps between the side wall of the opening 511 and the motor body 551, and between the blade of the first fan blade 541 and the motor body 551; fresh air can enter the fan blade cavity 53 through these gaps; thus, the setting of the opening 511 does not affect the setting of the fan blade motor 55, and the fan blade motor 55 occupies little space outside the fan blade cavity 53, making it widely applicable.

[0069] The end of the opening 511 away from the blade cavity 53 is a flared structure, that is, the inner diameter of the opening 511 gradually increases from the inside to the outside along the axial direction of the blade cavity 53, so as to allow more fresh air to enter the blade cavity 53 through the opening 511.
