Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a clothing processing device. Background Technology

[0002] Washing machines, dryers, and other clothing handling devices are household appliances that use electrical energy to generate mechanical action to clean clothes. As consumers' living standards improve, their demands for clothing handling devices are also increasing.

[0003] Clothing handling devices typically include a housing and a drum assembly. The drum assembly is located inside the housing and includes an outer drum and an inner drum. The inner drum forms a clothing handling chamber and is rotatably disposed inside the outer drum. A drying air duct is usually provided inside the housing and communicates with the clothing handling chamber to dry the clothing inside the chamber.

[0004] In related direct-venting clothing processing devices, energy consumption is high during the drying process, and the direct discharge of hot and humid air into the external space can easily cause the surrounding temperature and humidity to rise, causing inconvenience to users. Utility Model Content

[0005] The purpose of this invention is to provide a clothing processing device that optimizes the structure of the drying duct, reduces energy consumption, and achieves condensation and cooling of the exhaust air.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] According to one aspect of the present invention, a clothing processing device is provided, comprising: a housing configured as an outer shell of the clothing processing device; an inner cylinder rotatably disposed inside the housing, the inner cylinder forming a clothing processing cavity; an air inlet on the outer wall of the inner cylinder communicating with the clothing processing cavity; an air outlet disposed inside the housing, communicating with the clothing processing cavity; a fresh air fan disposed inside the housing, the air outlet end of the fresh air fan communicating with the air inlet; a heating element disposed inside the housing, the heating element being used to heat the air flowing through the fresh air fan; an exhaust fan disposed inside the housing, the air inlet end of the exhaust fan communicating with the air outlet; and a heat exchange unit comprising: a heat exchange shell covering the outer wall of the housing; and a fresh air inlet. On the outer wall of the heat exchange shell: an exhaust vent is provided on the outer wall of the heat exchange shell and is spaced apart from the fresh air vent; an air inlet duct is provided inside the heat exchange shell, one end of the air inlet duct is connected to the fresh air vent, and the other end of the air inlet duct is connected to the air inlet end of the fresh air fan; an air outlet duct is provided inside the heat exchange shell, and the air outlet duct is arranged alternately with the air inlet duct; one end of the air outlet duct is connected to the exhaust vent, and the other end of the air outlet duct is connected to the air outlet end of the exhaust fan; a heat exchange core is provided inside the heat exchange shell and is located at the intersection of the air inlet duct and the air outlet duct; a first heat exchange chamber and a second heat exchange chamber are formed in an alternately arranged manner; the first heat exchange chamber is connected to the air inlet duct, and the second heat exchange chamber is connected to the air outlet duct.

[0008] The above-mentioned technical solution has the following advantages or beneficial effects: Fresh air with low temperature and low humidity from the outside can enter the air inlet channel through the fresh air vent, flow through the first heat exchange chamber, and then flow into the fresh air fan. After being heated by the heating element, it enters the clothing processing chamber through the air inlet. The humid and hot air inside the clothing processing chamber can enter the air outlet duct through the exhaust fan, flow through the second heat exchange chamber, and then be discharged to the outside environment through the exhaust vent. Specifically, within the heat exchange core, when the fresh air with low temperature and low humidity from the outside flows through the first heat exchange chamber and the humid and hot air inside flows through the second heat exchange chamber, heat exchange occurs between them, causing the humid and hot air to be discharged as dry and cool air, preventing moisture from affecting the external environment. Simultaneously, the fresh air with low temperature and low humidity can be preheated, reducing the heating power consumption of the heating element and reducing energy consumption. This not only reduces the temperature and humidity of the discharged gas but also significantly improves the user's operating environment and experience, making it an energy-saving and environmentally friendly design. Furthermore, the structural design of the heat exchange unit simplifies the heat exchange structure of the clothing processing device, which helps to reduce the overall size of the machine and lower costs.

This enables fresh air entering the air inlet duct to smoothly enter the fresh air fan and then into the garment processing chamber. Simultaneously, the second pair of interfaces can be connected to the air outlet of the exhaust fan, allowing the air outlet duct to connect with the air outlet of the exhaust fan. This enables the humid and hot air flowing through the exhaust fan to smoothly enter the air outlet duct and then be discharged into the external environment. This ensures efficient circulation of fresh air, improving the air intake, exhaust, and drying efficiency of the garment processing equipment.

[0015] In some embodiments of this application, the fresh air vents and the exhaust vents are arranged circumferentially at intervals on the outer wall of the heat exchange shell.

[0016] The above-mentioned technical solution has the following advantages or beneficial effects: by circumferentially arranging the fresh air vents and exhaust vents on the outer wall of the heat exchange shell, it is convenient to arrange the air inlet duct and the air outlet duct in an alternating manner inside the heat exchange shell, which facilitates the layout of the fresh air vents and the exhaust vents, and further facilitates the connection between one end of the air inlet duct and the fresh air vent, as well as the connection between one end of the air outlet duct and the exhaust vent.

[0017] In some embodiments of this application, the heat exchange housing is provided with a drain outlet, which is located at the bottom of the air outlet duct and below the heat exchange core; the condensate generated by the heat exchange core can be discharged through the drain outlet.

[0018] The above-mentioned technical solution has the following advantages or beneficial effects: During the drying process, the condensate generated by the heat exchange core can flow along the second heat exchange chamber into the air outlet duct and flow to the drain at the bottom of the air outlet duct, so that the condensate can be discharged through the drain.

[0049] This application discloses a garment handling device, as described below. Figures 1-15 The clothing processing device of this application will be described using a clothes dryer as an example.

[0050] Figure 1 This is a schematic diagram of the structure of a clothing processing device according to some embodiments of the present invention.

[0051] like Figure 1 As shown, the garment processing device provided in this embodiment of the present invention may include a housing 1. The housing 1 may be constructed as the outer shell of the garment processing device. The housing 1 may typically have a hollow cuboid structure. It should be noted that in other embodiments, the external shape of the housing 1 may be designed as needed, and is not limited here. The interior of the housing 1 may be used to provide installation space.

[0052] In some embodiments, a clothing inlet (not shown in the figure) may be provided on the front side wall of the housing 1. This clothing inlet can connect to the internal space of the housing 1. Clothes can be placed into the housing 1 through the clothing inlet for washing.

[0053] It should be noted that in some other embodiments, when the clothing handling device is a pulsator washing machine, the clothing inlet can also be located on the top side wall of the casing 1.

[0054] like Figure 1 As shown, in some embodiments, a door cover 11 may be provided on the front side wall of the housing 1. The door cover 11 can be used to open and close the clothing inlet on the front side wall of the housing 1, thereby opening and closing the space inside the housing 1 through the door cover 11.

[0055] It should be noted that in some other embodiments, when the clothes handling device is a pulsator washing machine, the door cover 11 may also be located on the top side wall of the casing 1.

[0056] In some embodiments, the door cover 11 and the housing 1 can be connected by a hinge, and the door cover 11 can rotate about the axis of the hinge, thereby realizing the opening and closing of the door cover 11 and opening and closing the clothing inlet.

[0057] like Figure 1 As shown, in some embodiments, the bottom of the housing 1 may be provided with support legs 12. Multiple support legs 12 may be provided. The multiple support legs 12 may be spaced apart from each other and not rest on the bottom of the housing 1. Thus, the multiple support legs 12 cooperate to stably support the housing 1 and the entire garment processing device on the ground or other work surface.

[0058] Figure 2 yes Figure 1 Internal structural diagram. Figure 3 yes Figure 1 The front view. Figure 4 yes Figure 3 A partial cross-sectional view along the AA direction.

[0059] like Figure 2 and Figure 4 As shown, in some embodiments, the garment handling device may include an inner drum 2. The inner drum 2 may be disposed inside the housing 1. The inner drum 2 may extend along the front-rear direction of the housing 1. A garment handling chamber 20 may be formed inside the inner drum 2. The garment handling chamber 20 inside the inner drum 2 is used to hold garments to be washed. The garment inlet is directly opposite and communicates with the garment handling chamber 20. When the door cover 11 is opened, the garments can be placed into the garment handling chamber 20 inside the inner drum 2 through the garment inlet on the front side of the housing 1 for washing, dehydration, drying, and other operations. When the housing 1 is closed, the housing 1 can simultaneously close the garment inlet and the garment handling chamber 20.

[0060] In some embodiments, the inner drum 2 can be rotatably disposed inside the housing 1. When the inner drum 2 rotates relative to the housing 1, the inner drum 2 can drive the clothes to rotate relative to the housing 1, thereby achieving uniformity in washing, dehydrating, and drying the clothes in the clothes processing chamber 20 of the inner drum 2.

[0061] It should be noted that in some embodiments, the garment handling device may also include an outer tube (not shown in the figure). The outer tube may be disposed inside the housing 1. The inner tube 2 may be rotatably disposed inside the outer tube.

[0062] like Figure 4 As shown, in some embodiments, a drive device 3 may be provided inside the housing 1. The drive device 3 may be located inside the housing 1. The drive device 3 may be connected to the inner drum 2 in a transmission manner. The drive device 3 can drive the inner drum 2 to rotate relative to the housing 1, thereby realizing the drying, washing or dehydration functions of the clothing processing chamber 20 in the inner drum 2.

[0063] In some embodiments, the drive device 3 may include a drive shaft 31. The drive shaft 31 may be rotatably connected to the axis of the housing 1. The drive shaft 31 may be coaxially connected to the axis of the inner cylinder 2. The drive device 3 may drive the drive shaft 31 to rotate, thereby driving the inner cylinder 2 to rotate inside the outer cylinder.

[0064] like Figure 3 and Figure 4 As shown, in some embodiments, the drive device 3 may include a drive motor 32. The drive motor 32 may be disposed inside the housing 1. The output shaft of the drive motor 32 may be connected to the transmission shaft 31. Thus, when the drive motor 32 is working, the output shaft of the drive motor 32 may drive the transmission shaft 31 to rotate, thereby driving the inner cylinder 2 to rotate inside the housing 1 via the transmission shaft 31.

Figure 7 yes Figure 4 A schematic diagram of the structure of the mounting base 4. Figure 8 yes Figure 7 A schematic diagram of its decomposition. Figure 9 yes Figure 7 A structural diagram from another perspective. Figure 10 yes Figure 9 A schematic diagram of its decomposition.

[0066] like Figure 4 , Figure 6 and Figure 10As shown, in some embodiments, the garment handling device may include a mounting base 4. The mounting base 4 may be located inside the housing 1. The mounting base 4 may be located at the rear end of the housing 1. The mounting base 4 may be located on the back side of the inner tub 2. A drive device 3 may be installed within the mounting base 4. A drive shaft 31 may be rotatably connected to the axis of the mounting base 4. A drive motor 32 may be mounted on the mounting base 4 so that the output shaft of the drive motor 32 is connected to the drive shaft 31 for transmission. Thus, the mounting base 4 provides space for the installation and fixation of the drive device 3, allowing the drive motor 32 and the drive shaft 31 to cooperate, enabling the inner tub 2 to be rotatably connected to the front side of the mounting base 4, and stably driving the inner tub 2 to rotate inside the housing 1.

[0067] In some embodiments, an air inlet 21 may be provided on the outer wall of the inner cylinder 2. A fresh air fan 41 may be provided inside the housing 1. The air inlet of the fresh air fan 41 may be connected to the outside of the housing 1. The air outlet of the fresh air fan 41 may be connected to the air inlet 21. The air inlet 21 may connect the clothing processing chamber 20 and the air outlet of the fresh air fan 41. Thus, when the fresh air fan 41 is running, the airflow of the fresh air fan 41 can deliver low-temperature, low-humidity fresh air from outside the housing 1 into the clothing processing chamber 20 inside the inner cylinder 2 through the air inlet 21.

[0068] In some embodiments, the fresh air fan 41 can be housed within the mounting base 4. This design secures the fresh air fan 41 and helps save installation space.

[0069] In some embodiments, the air inlet of the fresh air fan 41 may be exposed on the rear side wall of the mounting base 4. This facilitates the installation of the fresh air fan 41 within the mounting base 4. Furthermore, it also facilitates communication between the air inlet of the fresh air fan 41 and the exterior of the housing 1.

[0070] like Figure 4 and Figure 10 As shown, in some embodiments, the garment processing device may include a heating element 42. The heating element 42 may be disposed inside the housing 1. The heating element 42 may be used to heat the air flowing through the fresh air blower 41. Thus, when the fresh air blower 41 delivers fresh air from outside the housing 1 into the garment processing chamber 20 inside the inner drum 2 through the air inlet 21, the heating element 42 can heat the air flowing through the fresh air blower 41, and then input hot air into the garment processing chamber 20 inside the inner drum 2 through the air inlet 21, using the hot air to dry the clothes in the garment processing chamber 20, thereby realizing the drying or clothes-drying function of the garment processing device.

[0071] like Figure 6 and Figure 10As shown, in some embodiments, the heating element 42 can be located on the air outlet side of the fresh air fan 41. The heating element 42 can be located between the air outlet of the fresh air fan 41 and the air inlet 21. In this way, the fresh air fan 41 can draw air from outside the casing 1, heat it by passing it through the heating element 42, and then input the hot air into the clothing processing chamber 20 inside the inner drum 2 through the air inlet 21.

[0072] It should be noted that in some other embodiments, the heating element 42 may also be located on the air inlet side of the fresh air fan 41.

[0073] like Figure 4 As shown, in some embodiments, the air inlet 21 can be located on the rear wall of the inner cylinder 2. The air inlet 21 can be located on the rear side of the clothing processing chamber 20. The fresh air fan 41 can be located on the mounting base 4. The fresh air fan 41 can be located on the back side of the air inlet 21. In this way, the fresh air fan 41 can draw air from outside the housing 1 into the housing 1, heat it after it is heated by the heating element 42, and then deliver it into the clothing processing chamber 20 through the air inlet 21 on the rear wall of the inner cylinder 2, thereby realizing the fresh air drying function for the clothes in the clothing processing chamber 20, which can effectively prevent the clothes from producing odors after drying.

[0074] like Figure 2 and Figure 4 As shown, in some embodiments, the rear wall of the inner drum 2 may be provided with multiple air inlets 21. These multiple air inlets 21 can be arranged at intervals on the rear wall of the inner drum 2. In this way, the multiple air inlets 21 can work together to deliver hot air to different areas of the garment processing chamber 20, improving the drying efficiency and uniformity of the garment processing chamber 20. It should be noted that the number and position of the air inlets 21 on the rear wall of the inner drum 2 can be adjusted as needed and are not limited here.

[0075] like Figure 4 , Figure 9 and Figure 10 As shown, in some embodiments, the garment processing device may include an air guide shroud 5. The air guide shroud 5 may be disposed inside the housing 1. The air guide shroud 5 may be located on the rear side of the rear wall of the inner cylinder 2. The air guide shroud 5 may be mounted and fixed on the front side of the mounting base 4. An air inlet cavity 50 may be formed between the rear wall of the inner cylinder 2 and the air guide shroud 5. The air outlet of the fresh air fan 41 may communicate with the air inlet cavity 50. The air inlet hole 21 may connect the air inlet cavity 50 and the garment processing cavity 20. In this way, the fresh air fan 41 can introduce fresh air from outside the housing 1 into the air inlet cavity 50. The air guide shroud 5 and the air inlet cavity 50 can guide and distribute the airflow, and then deliver it into the garment processing cavity 20 through the air inlet hole 21, so that the air guided by the air guide shroud 5 can smoothly enter each area of ​​the garment processing cavity 20, thereby improving the uniformity and drying efficiency of garment drying.

[0076] In some embodiments, the drive shaft 31 can be disposed at the center of the air guide shroud 5. One end of the drive shaft 31 can extend into the air inlet cavity 50 and be connected to the rear wall of the inner cylinder 2. In this way, the drive motor 32 can drive the inner cylinder 2 to rotate relative to the air guide shroud 5 through the drive shaft 31.

[0077] In some embodiments, the heating element 42 may be disposed between the fresh air blower 41 and the air inlet chamber 50. Thus, when the fresh air blower 41 operates, the fresh air drawn from outside the casing 1 by the fresh air blower 41 first flows through the heating element 42. In the heating element 42, the air is heated, and its temperature rises. This heated air is then introduced into the air inlet chamber 50. Finally, the hot air enters the clothing processing chamber 20 from the air inlet chamber 50 through the air inlet hole, thus ensuring both the freshness of the air in the clothing processing chamber 20 and providing dry, hot air.

[0078] It should be noted that in some other embodiments, the heating element 42 may also be disposed within the air inlet cavity 50.

[0079] like Figure 10 As shown, in some embodiments, an air inlet 51 can be formed on the rear wall of the air guide shroud 5. The air inlet 51 can connect the air outlet of the fresh air fan 41 and the air inlet cavity 50. A heating element 42 can be installed at the air inlet 51. The heating element 42 can be arranged adjacent to the fresh air fan 41. In this way, by installing the heating element 42 at the air inlet 51, the air entering the air inlet cavity 50 can be effectively heated, so that the fresh air drawn from outside the casing 1 by the fresh air fan 41 can be heated by the heating element 42, thereby improving heating efficiency.

[0080] like Figure 4 and Figure 6 As shown, in some embodiments, the housing 1 may be provided with an air outlet 13. The air outlet 13 is connected to the clothes processing chamber 20. The housing 1 may be provided with an exhaust fan 43. The air inlet of the exhaust fan 43 may be connected to the air outlet 13. The air outlet of the exhaust fan 43 may be connected to the outside of the housing 1. The air outlet 13 can connect the clothes processing chamber 20 and the air inlet of the exhaust fan 43. Thus, when the exhaust fan 43 is running, the airflow of the exhaust fan 43 can exhaust the air in the clothes processing chamber 20 to the outside of the housing 1 through the air outlet 13. Therefore, during the clothes drying process, the hot and humid air generated after the drying airflow in the clothes processing chamber 20 comes into contact with the wet clothes can be discharged through the air outlet 13 and the exhaust fan 43.

[0081] In some embodiments, the garment handling device may include an exhaust duct 14. The exhaust duct 14 may be located inside the housing 1 or outside the inner drum 2. One end of the exhaust duct 14 may be connected to an air outlet 13. The other end of the exhaust duct 14 may be connected to the air inlet of an exhaust fan 43. Thus, during the garment drying process, the hot and humid air inside the garment handling chamber 20 can be sequentially discharged outside the housing 1 through the air outlet 13, the exhaust duct 14, and the exhaust fan 43. The coordinated use of the exhaust duct 14 and the exhaust fan 43 ensures smooth airflow within the garment handling chamber 20, which is beneficial for improving drying efficiency.

[0082] In some embodiments, a filter (not shown) may be provided inside the exhaust duct 14. The filter can filter the air flowing through the exhaust duct 14 before discharging the air from the exhaust duct 14 to the outside of the housing 1. When the air in the clothing processing chamber 20 flows in the exhaust duct 14, it carries various tiny particles, dust, or lint. The filter can effectively capture and intercept these particles, dust, or lint, preventing them from being discharged to the outside of the housing 1, ensuring cleaner exhaust air and reducing pollution to the surrounding environment. In addition, regularly replacing or cleaning the filter can maintain the efficiency of the exhaust system and ensure its long-term stable operation.

[0083] It should be noted that in some other embodiments, the filter screen may be replaced by other filter elements.

[0084] In some embodiments, the exhaust duct 14 can extend along the front-rear direction of the housing 1. The air outlet 13 can be located on the housing 1 at the front side of the inner cylinder 2. The air outlet 13 can be located on the front wall of the housing 1. The front end of the exhaust duct 14 can communicate with the air outlet 13. The exhaust fan 43 can be located at the rear end of the housing 1. The rear end of the exhaust duct 14 can communicate with the air inlet of the exhaust fan 43. Thus, the air inlet 21 can introduce fresh hot air from the rear end of the garment processing chamber 20 into the garment processing chamber 20, and allow the humid and hot air in the garment processing chamber 20 to be discharged through the air outlet 13 at its front end, and then discharged along the exhaust duct 14 and the exhaust fan 43 at its rear end, forming a complete drying airflow path. This design is both efficient and practical, ensuring smooth airflow within the garment processing chamber 20 and maintaining a good drying environment within the garment processing chamber 20, thereby improving drying efficiency and ensuring the quality of garment processing.

[0085] In some embodiments, the exhaust duct 14 may be located in the bottom region of the housing 1. The exhaust duct 14 may be located below the bottom of the inner cylinder 2. In this way, placing the exhaust duct 14 in the bottom region of the housing 1 is beneficial for the exhaust of hot and humid air in the exhaust duct 14, and facilitates the discharge or collection of some of the condensate generated by the hot and humid air nearby.

[0086] like Figure 4 and Figure 8 As shown, in some embodiments, the exhaust fan 43 can be housed within the mounting base 4. This design provides a secure fit for the exhaust fan 43 and helps save installation space.

[0087] In some embodiments, the exhaust fan 43 may have its outlet end exposed on the rear side wall of the mounting base 4. This facilitates the installation of the exhaust fan 43 within the mounting base 4. Furthermore, it also facilitates communication between the exhaust fan 43's outlet end and the exterior of the housing 1.

[0088] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the clothing handling device may include a heat exchange unit 6. The heat exchange unit 6 can be used to exchange heat between the low-temperature, low-humidity fresh air flowing through the fresh air fan 41 and the humid, hot air flowing through the exhaust fan 43. Through this exchange, the low-temperature, low-humidity outside air is preheated, thereby reducing the heating power consumption of the heating element 42 and avoiding energy loss from directly exhausting high-temperature air. Simultaneously, the high-temperature, high-humidity air inside provides preheating heat for the intake air during exhaust, achieving energy recycling. Moreover, during the cooling process, some moisture condenses in the high-humidity air, which is condensed and stored in the heat exchange unit 6, further reducing energy consumption. This not only reduces the temperature and humidity of the exhaust air but also significantly improves the user's environment and experience, making it an energy-saving and environmentally friendly design.

[0089] Figure 11 yes Figure 6 A schematic diagram of the structure of the heat exchange unit 6. Figure 12 yes Figure 11 A schematic diagram of its decomposition.

[0090] like Figure 6 , Figure 11 and Figure 12As shown, in some embodiments, the heat exchange unit 6 may include a heat exchange housing 61. The heat exchange housing 61 may be installed on the outer wall of the housing 1, serving a protective and support function. The outer wall of the heat exchange housing 61 may be provided with a fresh air inlet 611 and an exhaust inlet 612. The fresh air inlet 611 and the exhaust inlet 612 may be arranged at intervals. Low-temperature, low-humidity fresh air from the outside can enter the heat exchange housing 61 through the fresh air inlet 611 and flow to the fresh air fan 41. Humid and hot air flowing through the exhaust fan 43 can flow into the heat exchange housing 61 and be discharged to the outside through the exhaust inlet 612. Thus, through the cooperation of the fresh air inlet 611 and the exhaust inlet 612 on the heat exchange housing 61, the fresh air inlet 611 allows low-temperature, low-humidity fresh air from the outside to enter the heat exchange housing 61, while the exhaust inlet 612 is used to discharge the humid and hot air flowing through the exhaust fan 43 and release it to the outside. Low-temperature, low-humidity fresh air and humid, warm air can exchange heat inside the heat exchange housing 61. This design achieves an efficient combination of airflow and heat exchange. The spaced arrangement of the fresh air vents 611 and exhaust vents 612 helps maintain uniform airflow and improves heat exchange efficiency.

[0091] Figure 13 yes Figure 11 The front view. Figure 14 yes Figure 13 A cross-sectional view.

[0092] like Figure 14 As shown, in some embodiments, an air inlet duct 62 may be provided inside the heat exchange housing 61. One end of the air inlet duct 62 may be connected to the fresh air inlet 611. The other end of the air inlet duct 62 may be connected to the air inlet end of the fresh air fan 41. In this way, fresh air with low temperature and low humidity from the outside can enter the air inlet duct 62 through the fresh air inlet 611, and then be drawn in by the air inlet end of the fresh air fan 41. After being heated by the heating element 42, it provides hot air to the clothing processing chamber 20, thereby providing the required fresh air to the clothing processing chamber 20.

[0093] In some embodiments, an air outlet duct 63 may be provided inside the heat exchange housing 61. One end of the air outlet duct 63 may be connected to the exhaust port 612. The other end of the air outlet duct 63 may be connected to the exhaust port of the exhaust fan 43. In this way, the hot and humid air inside the clothing processing chamber 20 can enter the exhaust duct 14 through the exhaust port 13, be drawn in by the exhaust fan 43, enter the air outlet duct 63, and then be discharged to the external environment through the exhaust port 612. In short, through the coordinated operation of the air outlet duct 63, the exhaust port 612, and the exhaust fan 43, the hot and humid air inside the clothing processing chamber 20 is effectively discharged, thereby maintaining air circulation and a dry environment inside the clothing processing chamber 20.

[0094] In some embodiments, the heat exchange housing 61 can be detachably mounted on the outer wall of the housing 1. When the heat exchange housing 61 is mounted on the outer wall of the housing 1, the air inlet of the fresh air fan 41 can be connected to the air inlet duct 62, and the air outlet of the exhaust fan 43 can be connected to the exhaust duct 14. This facilitates the overall installation of the heat exchange unit 6 and simplifies the installation process.

[0095] In some embodiments, the heat exchange housing 61 is mounted on the rear wall of the housing 1. The fresh air fan 41 and the exhaust fan 43 can be respectively located at the rear end of the housing 1. When the heat exchange housing 61 is mounted on the rear wall of the housing 1, the air inlet of the fresh air fan 41 can be connected to the air inlet duct 62, and the air outlet of the exhaust fan 43 can be connected to the exhaust duct 14.

[0096] In some embodiments, an opening may be provided on the rear wall of the housing 1. The mounting base 4 may be located at the rear end inside the housing 1, and the mounting base 4 may be exposed at the opening on the rear wall of the housing 1. The heat exchange housing 61 covers the opening on the rear wall of the housing 1.

[0097] In some embodiments, the air inlet duct 62 and the air outlet duct 63 may be arranged alternately inside the heat exchange housing 61. The air inlet duct 62 and the air outlet duct 63 may be arranged alternately in the front-rear direction of the housing 1. The air inlet duct 62 and the air outlet duct 63 may be arranged alternately along the axial direction of the inner cylinder 2.

[0098] like Figure 6 and Figure 14 As shown, in some embodiments, a first pair of interfaces 613 may be provided on the front wall of the heat exchange housing 61. The first pair of interfaces 613 may be arranged directly opposite the air inlet end of the fresh air fan 41. The first pair of interfaces 613 is located at the end of the air inlet duct 62 away from the fresh air hole 611. The first pair of interfaces 613 can connect the air inlet end of the fresh air fan 41 and the air inlet duct 62. Thus, when the heat exchange housing 61 is covered on the rear wall of the housing 1, the first pair of interfaces 613 can be connected to the air inlet end of the fresh air fan 41, so that the air inlet duct 62 can be connected to the air inlet end of the fresh air fan 41, thereby allowing the fresh air entering the air inlet duct 62 to smoothly enter the fresh air fan 41, and then enter the clothing processing chamber 20. This ensures that the fresh air can circulate efficiently, improving the air intake effect and drying efficiency of the clothing processing equipment.

[0099] In some embodiments, a second pair of interfaces 614 may be provided on the front wall of the heat exchange housing 61. The second pair of interfaces 614 may be arranged directly opposite the air outlet end of the exhaust fan 43. The second pair of interfaces 614 is located at the end of the air outlet duct 63 away from the exhaust hole 612. The second pair of interfaces 614 may connect the air outlet end of the exhaust fan 43 and the air outlet duct 63. Thus, when the heat exchange housing 61 is covered on the rear wall of the housing 1, the second pair of interfaces 614 and the air outlet end of the exhaust fan 43 can be connected, so that the air outlet duct 63 and the air outlet end of the exhaust fan 43 can be connected, thereby allowing the hot and humid air flowing through the exhaust fan 43 to smoothly enter the air outlet duct 63 and then be discharged into the external environment. This ensures that the hot and humid air can circulate efficiently, improving the exhaust effect and drying efficiency of the clothing processing equipment.

[0100] like Figure 6 and Figure 12 As shown, in some embodiments, the fresh air vent 611 and the exhaust vent 612 can be arranged circumferentially at intervals on the outer wall of the heat exchange shell 61. This facilitates the staggered arrangement of the inlet air duct 62 and the outlet air duct 63 inside the heat exchange shell 61, simplifying the layout of the fresh air vent 611 and the exhaust vent 612, and further facilitating communication between one end of the inlet air duct 62 and the fresh air vent 611, and between one end of the outlet air duct 63 and the exhaust vent 612.

[0101] Figure 15 yes Figure 12 A schematic diagram of the structure of the heat exchanger core 64.

[0102] like Figure 14 and Figure 15As shown, in some embodiments, the heat exchange unit 6 may include a heat exchange core 64. The outlet air duct 63 may be arranged alternately with the inlet air duct 62. The heat exchange core 64 may be disposed within the heat exchange housing 61, and may be located at the intersection of the inlet air duct 62 and the outlet air duct 63. The heat exchange core 64 may contain an alternately arranged first heat exchange chamber 641 and a second heat exchange chamber 642. The first heat exchange chamber 641 and the second heat exchange chamber 642 may be isolated from each other. The first heat exchange chamber 641 may be connected to the inlet air duct 62. The second heat exchange chamber 642 may be connected to the outlet air duct 63. Thus, fresh air with low temperature and low humidity from the outside enters the air inlet channel through the fresh air inlet 611, flows through the first heat exchange chamber 641, and then flows into the fresh air fan 41 through the first pair of interfaces 613. The hot and humid air in the exhaust duct 14 enters the outlet duct 63 through the exhaust fan 43 and the second pair of ports 614, then flows through the second heat exchange chamber 642, and is finally discharged to the outside environment through the exhaust hole 612. Within the heat exchange core 64, when the cool, low-humidity fresh air from the outside flows through the first heat exchange chamber 641 and the hot and humid air inside flows through the second heat exchange chamber 642, heat exchange occurs, causing the hot and humid air to become dry and cool air before being discharged, preventing moisture from affecting the outside environment. Simultaneously, the cool, low-humidity fresh air can be preheated, reducing the heating power consumption of the heating element 42.

[0103] like Figure 15 As shown, in some embodiments, the heat exchange core 64 may include a plurality of first heat exchange chambers 641 and a plurality of second heat exchange chambers 642. The plurality of first heat exchange chambers 641 and the plurality of second heat exchange chambers 642 may be arranged alternately along the thickness direction of the heat exchange core 64. That is, a second heat exchange chamber 642 may be provided between two adjacent first heat exchange chambers 641, and a first heat exchange chamber 641 may be provided between two adjacent second heat exchange chambers 642. In this way, when the ambient cold and low-humidity fresh air flows through the heat exchange core 64, it can simultaneously flow through multiple first heat exchange chambers 641. When the interior humid and hot air flows through the heat exchange core 64, it can simultaneously flow through multiple second heat exchange chambers 642. This design can increase the heat exchange area between the cold and low-humidity fresh air and the humid and hot air, thereby improving the condensation efficiency of the humid and hot air and the preheating efficiency of the fresh air.

[0104] like Figure 12As shown, in some embodiments, a mounting cavity 615 may be provided within the heat exchange housing 61. The mounting cavity 615 may be formed at the intersection of the inlet air duct 62 and the outlet air duct 63. The heat exchange core 64 is detachably embedded in the mounting cavity 615. Thus, when the heat exchange core 64 is not installed in the mounting cavity 615, the mounting cavity 615 can communicate with both the inlet air duct 62 and the outlet air duct 63. When the heat exchange core 64 is embedded in the mounting cavity 615, the first heat exchange cavity 641 can communicate with the inlet air duct 62, and the second heat exchange cavity 642 can communicate with the outlet air duct 63, facilitating the installation, removal, and replacement of the heat exchange core 64, making the maintenance and replacement of the heat exchange core 64 simple and quick.

[0105] like Figure 6 and Figure 12 As shown, in some embodiments, the mounting cavity 615 can communicate with the external space of the heat exchange housing 61. Thus, the heat exchange core 64 can be replaced on the heat exchange housing without disassembling the heat exchange housing 61, making the maintenance and replacement of the heat exchange core 64 simpler and faster.

[0106] like Figure 4 , Figure 12 and Figure 14 As shown, in some embodiments, the heat exchange housing 61 is provided with a drain port 65. The drain port 65 may be located at the bottom of the air outlet duct 63. The drain port 65 may be located below the heat exchange core 64. During the drying process, the condensate generated by the heat exchange core 64 can flow along the second heat exchange chamber 642 into the air outlet duct 63 and flow to the drain port 65 at the bottom of the air outlet duct 63, thereby allowing the condensate to be discharged through the drain port 65.

[0107] In some embodiments, the drain outlet 65 may be connected to the interior of the housing 1. The drain outlet 65 may also be connected to the exterior of the housing 1 via a drain pipe (not shown). Thus, during the drying process, condensate generated by the condensation of hot and humid air can be discharged to the exterior of the housing 1 through the drain outlet 65 and the drain pipe.

[0108] It should be noted that in some other embodiments, a water collection box (not shown in the figure) may also be provided inside the housing 1. The drain outlet 65 can be connected to the inside of the water collection box through a drain pipe. In this way, during the drying process, the condensate generated by the condensation of hot and humid air can be discharged into the water collection box through the drain outlet 65 and the drain pipe, and stored in the water collection box for periodic discharge or recycling.

[0109] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
