[0019] In one embodiment, the frequency converter further includes a heat sink connected to the frequency converter control board, the heat sink passing through the communication port and partially located within the drying tunnel.

[0020] In one embodiment, a first seal is further included, which is disposed circumferentially along the communication port to seal the gap between the heat sink and the wall of the communication port.

[0021] In one embodiment, the heat sink is located between the condenser and the evaporator, along the direction of airflow within the duct.

[0047] This application provides a clothing processing device. The clothing processing device can be a dryer or a washing machine with integrated drying function, used to dry clothes, etc. After being dried by the clothing processing device, damp clothes can be worn immediately, greatly improving people's quality of life.

[0048] Please refer to Figures 1 to 3 The garment processing device 100 includes a housing, a drum assembly 50, a drying tunnel shell 20, a fan 70, a heat pump system 30, and a frequency converter 40.

[0049] The housing constitutes the outer shell of the garment processing device 100, providing a mounting base and protection for components such as the drum assembly 50, drying tunnel shell 20, fan 70, and heat pump system 30. The surface of the housing also forms the main exterior appearance of the garment processing device 100. The housing includes a base 10, which supports the garment on the ground or mounting surface. The drum assembly 50, drying tunnel shell 20, fan 70, heat pump system 30, and frequency converter 40 are all mounted on the base 10.

[0050] The bucket assembly 50 is a structure in the clothing handling device 100 that is mainly used to provide clothing handling function. The bucket assembly 50 defines a clothing handling chamber and an inlet communicating with the clothing handling chamber. Clothes can be put into the clothing handling chamber through the inlet or taken out of the clothing handling chamber through the inlet.

[0051] The drying tunnel shell 20 is connected to the base 10, and together with the base 10, defines the drying tunnel 60 and the first and second air vents connecting the drying tunnel 60 and the garment processing chamber. Understandably, gas can flow into the garment processing chamber through the drying tunnel 60 to dry the garments. The drying tunnel shell 20 is made of metal or other heat-resistant materials to have sufficient strength and good resistance to high-temperature airflow, thus improving the service life of the drying tunnel shell 20. Alternatively, the drying tunnel shell 20 can also be connected to the base 10 and define the drying tunnel 60 and the first and second air vents itself.

[0052] The fan 70 is connected to the base 10 and includes a motor 71 and an impeller 72. The impeller 72 is disposed inside the drying tunnel 60 and connected to the output end of the motor 71 so that it rotates under the drive of the motor 71. The rotating impeller 72 drives the airflow through the first air inlet into the garment processing chamber, and after processing the garments, it flows into the drying tunnel 60 from the second air inlet. Optionally, the first air inlet is disposed near the bottom of the garment processing chamber, and the second air inlet is disposed near the loading port.

[0053] The heat pump system 30 is capable of forming a refrigerant circulation and is used to heat the airflow flowing through the drying duct 60. The heat pump system 30 includes a compressor 31, a condenser 33, and an evaporator 32. The compressor 31, condenser 33, and evaporator 32 are all disposed on the base 10, and the evaporator 32 and condenser 33 are arranged sequentially at intervals along the airflow direction in the drying duct 60 (from the second air outlet to the first air outlet). Understandably, the compressor 31, condenser 33, and evaporator 32 are connected via refrigerant piping. The specific principle is as follows: the compressor 31 draws in low-pressure gaseous refrigerant, compresses it, and discharges it at high pressure. The discharged high-pressure refrigerant enters the condenser 33, where it is cooled by ambient air and condenses into a high-pressure liquid (simultaneously transferring heat to the surrounding air). The high-pressure liquid refrigerant flows through the expansion valve 34, where it is throttled and depressurized, becoming a low-pressure, low-temperature gas-liquid two-phase mixture before entering the evaporator 32. The liquid refrigerant evaporates and cools in the evaporator 32 (simultaneously absorbing heat from the surrounding air). The resulting low-pressure gaseous refrigerant is then drawn back into the compressor 31 and pressurized, thus repeating the cycle continuously. This achieves heat exchange.

[0054] Therefore, the working process of the clothing processing device 100 during the clothing drying operation is as follows: the condenser 33 heats the airflow in the drying tunnel 60, generating high-temperature dry air at approximately 40℃ and 65℃. This dry air enters the clothing processing chamber through the first air vent. In the clothing processing chamber, the dry air flows over the surface of the wet clothing, exchanging heat and moisture with the clothing, absorbing the moisture and becoming high-temperature, high-humidity gas. This high-temperature, high-humidity gas exits the clothing processing chamber through the second air vent, then passes through the evaporator 32, where it is cooled into low-temperature, low-humidity gas before flowing back to the condenser 33. This cycle repeats continuously, achieving continuous and efficient drying of the clothing.

[0055] Optionally, the frequency converter 40 is electrically connected to the compressor 31 to control the speed of the compressor 31, adjust the heat output of the heat pump system 30, and optimize energy consumption. In related technologies, the frequency converter 40 is usually fixed on the base 10, but due to the large structural size of the frequency converter 40, it has the problems of high cost and large space occupation.

[0056] To solve the above problems, please combine... Figure 3 and Figure 4 In some embodiments of this application, the frequency converter 40 includes a housing 41 and a frequency conversion control board 42.

[0057] A cover 41 is fitted over the drying tunnel shell 20 and together with the drying tunnel shell 20 defines the mounting cavity. A frequency converter control board 42 is disposed within the receiving cavity and is electrically connected to the compressor 31 to control the speed of the compressor 31. The cover 41 can be made of plastic or alloy. Using plastic offers advantages such as ease of manufacturing and lightweight structure, while using alloy provides better structural strength and heat dissipation performance. Specifically, the cover 41 forms a groove structure, with one side of the cover 41 having the groove opening connected to the drying tunnel shell 20, thereby allowing the drying tunnel shell 20 and the cover 41 to jointly define the aforementioned receiving cavity.

[0058] It should be noted that in embodiments where the garment handling device 100 includes a main control board, the variable frequency control board 42 is different from the main control board. The main control board is used to control the operation of the entire machine, while the variable frequency control board 42 is used to control the frequency conversion of the compressor 31. Optionally, the main control board and the variable frequency control board 42 can be integrated or set separately.

[0059] Understandably, in this embodiment, the cover 41 is placed over the drying tunnel shell 20 to form a cavity for housing the frequency converter control board 42. This makes the drying tunnel shell 20 a partial outer shell of the frequency converter 40. The drying tunnel shell 20 serves both to form the drying tunnel 60 and to jointly cover and protect the frequency converter control board 42 with the cover 41. Compared to related technologies, the frequency converter 40 in this embodiment uses the drying tunnel shell 20 as a partial shell. This not only reduces the material originally used to form the shell of the frequency converter 40, reducing the complexity of the cover 41 and saving costs, but also reduces the space occupied by the frequency converter 40 within the clothing processing device 100, resulting in a more compact structure and improved space utilization.

[0060] Combination Figure 3In some embodiments, the drying tunnel shell 20 includes a top shell 21 and a side shell 22. The side shell 22 is connected between the top shell 21 and the base 10 to jointly enclose and form the drying tunnel 60. Taking a horizontally placed garment processing device 100 as an example, with the inlet facing the horizontal direction, the base 10 is placed on the ground, and the side shell 22 is connected to the base 10 and extends vertically. The top shell 21 is located at the end of the side shell 22 away from the base 10 and is connected to the side shell 22, so that the top shell 21, the side shell 22, and the base 10 together enclose and form the drying tunnel 60. The side shell 22 and the base 10 can be connected by one or more of the following methods: bolt connection, snap-fit ​​connection, etc., which is not limited in this embodiment. The top shell 21 and the side shell 22 can be an integral structure with good structural integrity; or the top shell 21 and the side shell 22 can be formed separately and then connected by one or more of the following methods: bolt connection, snap-fit ​​connection, etc., for easy assembly. In embodiments where the top shell 21 and the side shell 22 are formed separately, the top shell 21 and the side shell 22 may be made of the same or different materials. For example, the top shell 21 may be made of plastic and the side shell 22 may be made of metal. This application does not limit this.

[0061] In one embodiment, the housing 41 covers the top housing 21. In related technologies, the inverter 40 is mounted on the base 10, which integrates various components of the clothing processing device 100, resulting in a complex structure, cramped space, and inconvenient structural arrangement. This embodiment, by placing the housing 41 over the top housing 21, moves the overall structure of the inverter 40 away from the base 10. This reduces the space occupied by the base 10, facilitating the arrangement of components on the base 10. Furthermore, placing it on the top housing 21 allows for the utilization of space near the top housing 21 within the clothing processing device 100's housing, improving space utilization.

[0062] In another embodiment, the cover 41 can also be installed over the side shell 22, which similarly allows the overall structure of the inverter 40 to be moved away from the base 10, reducing the space occupied by the base 10, facilitating the placement of various components on the base 10, and utilizing the space near the inner side shell 22 of the clothing processing device 100, thereby improving space utilization. Furthermore, when the cover 41 is located inside the side shell 22, removing the base 10 allows the cover 41 to be exposed through the drying tunnel 60 space provided by the base 10; when the cover 41 is located outside the side shell 22, removing the side panel of the housing that obstructs the side shell 22 allows the cover 41 to be exposed. This facilitates maintenance of the inverter 40 by personnel, improving work efficiency.

[0063] Of course, in one embodiment, the housing 41 may also cover the top housing 21 and the side housing 22. For some inverters 40 with more complex structures and larger volumes, part of the housing 41 can be covered by the top housing 21 and the other part by the side housing 22. This utilizes the space near the top housing 21 and the side housing 22, increases the spread area of ​​the inverter 40, reduces the thickness of the housing 41, avoids interference of the housing 41 with other devices, and improves space utilization.

[0064] The following is combined with Figure 3 as well as Figures 5 to 8 The explanation will continue with the example of the cover 41 covering the top cover 21.

[0065] In one embodiment, the housing 41 is connected to the outer surface of the top housing 21. For example... Figure 1 As shown, the drum assembly 50 is mounted above the drying tunnel shell 20. A space exists between the drum assembly 50 and the top shell 21. The cover 41 is placed over the top shell 21, positioning it between the top shell 21 and the drum assembly 50. This utilizes the space, improving space utilization and making the structure more compact. Furthermore, placing the cover 41 outside the top shell 21 minimizes the exposure of the frequency converter control board 42 within the drying tunnel 60, preventing moisture damage to the board. This also allows the cover 41 and the frequency converter control board 42 to be placed outside the top shell 21 after the top shell 21, side shells 22, and base 10 are assembled, facilitating easy assembly and disassembly.

[0066] Combination Figure 5 and Figure 6 In one embodiment, the drying tunnel shell 20 is provided with a connecting port 20a, which is covered by a cover 41. The shape of the connecting port 20a can be circular or square, etc., and is not limited here. The connecting port 20a connects the mounting cavity and the drying tunnel 60, and is located upstream of the condenser 33. The frequency converter control board 42 is provided with a frequency converter chip for controlling the compressor 31. In actual use, the frequency converter chip and other components will generate heat. As mentioned above, the airflow in the drying tunnel 60 is heated when it passes through the condenser 33. Compared with the airflow downstream of the condenser 33, the airflow temperature upstream of the condenser 33 is lower. Provided that the frequency converter control board 42 is waterproofed, the airflow upstream of the condenser 33 can flow into the mounting cavity through the connecting port 20a to carry away the heat dissipated by the frequency converter control board 42 during operation, thereby achieving heat dissipation of the frequency converter control board 42.

[0067] To improve heat dissipation of the frequency converter control board 42, in one embodiment, the frequency converter 40 further includes a heat sink 43. The specific material of the heat sink 43 is not limited, as long as it has good thermal conductivity; for example, it can be one or more of silver, copper, and aluminum. It should be noted that the heat sink 43 can be made of pure metal or an alloy. Figure 6As shown, the heat sink 43 is connected to the frequency converter control board 42, and the heat sink 43 passes through the communication port 20a and is partially located inside the drying tunnel 60. In this way, the heat of the frequency converter control board 42 is conducted to the heat sink 43, and the airflow in the drying tunnel 60 can exchange heat with the heat sink 43 when it flows through it, thereby achieving heat dissipation for the frequency converter control board 42.

[0068] Furthermore, the heat sink 43 includes a heat sink substrate 431 and a plurality of spaced heat sink fins 432, all disposed on one side of the heat sink substrate 431. The heat sink substrate 431 is connected to the frequency converter control board 42 and blocks the connection port 20a to prevent airflow within the drying tunnel 60 from entering the housing 41 through the connection port 20a and affecting the frequency converter control board 42. The plurality of heat sink fins 432 are located within the drying tunnel 60, and a flow channel is formed between adjacent heat sink fins 432. The flow channel is directed in the direction of airflow within the drying tunnel 60. By providing multiple heat sink fins 432, the contact area with the airflow within the drying tunnel 60 is increased, thereby further improving the cooling effect of the heat sink 43.

[0069] Furthermore, the extension direction of the flow channel is parallel to the airflow direction within the drying tunnel 60. This layout ensures that the airflow within the drying tunnel 60 can flow directly and smoothly through the flow channel without being obstructed by any obstacles. When the airflow within the drying tunnel 60 flows through the flow channel, it not only quickly removes heat from the heat dissipation fins 432, reducing the temperature of the frequency converter control board 42, but also maintains its original flow velocity. This design ensures that the airflow within the drying tunnel 60 does not slow down as it flows through the heat dissipation fins 432, thereby ensuring uniform heat distribution within the drying tunnel 60 and effectively transferring it to the clothes, improving drying efficiency.

[0070] Combination Figure 5 and Figure 6 In one embodiment, the connecting port 20a is disposed between the evaporator 32 and the condenser 33, and the portion of the heat sink 43 located within the drying tunnel 60 is also disposed between the evaporator 32 and the condenser 33. Understandably, the airflow in the drying tunnel 60 cools down after passing through the evaporator 32, and the low-temperature airflow can fully exchange heat with the heat sink 43 when it flows through it, carrying away more heat and further improving the heat dissipation effect.

[0071] It is understandable that by extending the heat sink 43 through the connecting port 20a into the drying tunnel 60, heat dissipation of the frequency converter control board 42 is achieved while keeping the frequency converter control board 42 outside the drying tunnel 60, thereby reducing the impact of airflow in the drying tunnel 60 on the frequency converter control board 42.

[0072] Combination Figure 6In one embodiment, the garment handling device 100 further includes a first sealing member 44, which is arranged circumferentially along the connecting opening 20a to seal the gap between the heat sink 43 and the wall of the connecting opening 20a. Optionally, the first sealing member 44 can be a high-temperature resistant sealant, which fills the gap between the heat sink 43 and the wall of the connecting opening 20a; or, the first sealing member 44 can be a sealing ring, which is annularly arranged and fitted onto the heat sink 43 to fill the gap between the heat sink 43 and the wall of the connecting opening 20a. The sealing ring is made of a high-temperature resistant rubber material, which improves the filling effect. Accordingly, the shape of the connecting opening 20a can be adapted to the shape of the heat sink 43. For example, the heat sink 43 is cylindrical and the connecting opening 20a is circular; or the heat sink 43 is prismatic and the connecting opening 20a is rectangular. The adaptation of the shapes of the connecting opening 20a and the heat sink 43 makes the first sealing member 44 around the heat sink 43 more uniform and improves the sealing effect. Thus, in this embodiment of the application, the first sealing element 44 is used to seal the connection port 20a, thereby isolating the airflow in the drying tunnel 60, preventing the frequency converter control board 42 from being affected by the moisture in the drying tunnel 60, and improving the reliability of the frequency converter 40.

[0073] Of course, the heat sink 43 can also be located entirely within the drying tunnel 60, and the first seal 44 is used to seal the connecting port 20a.

[0074] like Figure 7 and Figure 8As shown, in some other embodiments, the housing 41 is connected to the inner surface of the drying tunnel housing 20, thereby allowing the inverter 40 to utilize the space within the drying tunnel 60, keeping the overall structure of the inverter 40 away from the base 10, reducing the space occupied by the base 10, and facilitating the arrangement of various components on the base 10. Optionally, the housing 41 is provided with a connecting port 20a, which connects the mounting cavity and the drying tunnel 60 and is located upstream of the condenser 33. The shape of the connecting port 20a can be circular or square, etc., and is not limited here. In embodiments where the heat sink 43 is not located at the connecting port 20a, provided that the inverter control board 42 is waterproofed, the airflow upstream of the condenser 33 can flow into the mounting cavity through the connecting port 20a to carry away the heat dissipated by the inverter control board 42 during operation, thereby achieving heat dissipation for the inverter control board 42. Further, the heat sink 43 is connected to the inverter control board 42, and the heat sink 43 passes through the connecting port 20a and is partially located within the drying tunnel 60. The specific material and structure of the heat sink 43 are as described above and will not be repeated here. Thus, the heat from the frequency converter control board 42 is conducted to the heat sink 43, and the airflow within the drying tunnel 60 exchanges heat with the heat sink 43, thereby achieving heat dissipation for the frequency converter control board 42. The casing 41 is positioned between the evaporator 32 and the condenser 33, or the connecting port 20a on the casing 41 is positioned between the evaporator 32 and the condenser 33. The portion of the heat sink 43 located within the drying tunnel 60 is also positioned between the evaporator 32 and the condenser 33, further improving the heat dissipation effect. The first sealing member 44 is arranged circumferentially along the connecting port 20a to seal the gap between the heat sink 43 and the connecting port 20a, preventing the frequency converter control board 42 from being affected by moisture within the drying tunnel 60 and improving the reliability of the frequency converter 40.

[0075] Reference Figure 6 and Figure 8 To further improve the sealing performance of the inverter 40, the garment handling device 100 also includes a second seal 45 and a third seal.

[0076] The second sealing element 45 is disposed between the housing 41 and the drying tunnel housing 20, and extends circumferentially along the housing 41 to seal the gap between the housing 41 and the drying tunnel housing 20. Optionally, the second sealing element 45 can be made of high-temperature resistant sealant, which fills the gap between the housing 41 and the drying tunnel housing 20; or, the second sealing element 45 can also be a sealing ring that is easier to install and remove. The sealing ring is annular and extends circumferentially along the housing 41 to fill the gap between the housing 41 and the drying tunnel housing 20. The sealing ring is made of high-temperature resistant rubber material, which improves the filling effect. Thus, this embodiment of the application seals the gap between the housing 41 and the drying tunnel housing 20 by setting the second sealing element 45, isolating the airflow outside the mounting cavity, preventing the frequency converter control board 42 and other components inside the mounting cavity from being affected by moisture, and improving the reliability of the frequency converter 40.

[0077] In one embodiment, the garment handling device 100 further includes an electrical connection wire, through which the frequency converter control board 42 and the compressor 31 are connected. The compressor 31 is disposed outside the drying tunnel shell 20, and the shell 41, the drying tunnel shell 20, or both the shell 41 and the drying tunnel shell 20 are provided with a wire passage hole through which the electrical connection wire passes. A third sealing element is fitted onto the electrical connection wire to seal the gap between the electrical connection wire and the wall of the wire passage hole. Optionally, the third sealing element may be made of a high-temperature resistant sealant, which fills the gap between the electrical connection wire and the wall of the wire passage hole; or, the third sealing element may be a sealing ring that is easier to install and remove, which is annular and surrounds the electrical connection wire to fill the gap between the electrical connection wire and the wall of the wire passage hole. The sealing ring is made of a high-temperature resistant rubber material, which improves the filling effect. This embodiment seals the gap between the electrical connection wire and the hole wall of the wire passage by setting a third sealing element. This not only isolates the airflow outside the mounting cavity and prevents the frequency converter control board 42 and other components inside the mounting cavity from being affected by moisture, thus improving the reliability of the frequency converter 40, but also prevents airflow leakage for the wire passage hole set in the drying tunnel shell 20, ensuring the air pressure in the drying tunnel 60 to ensure airflow circulation, and preventing noise caused by airflow leakage.
