[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0047] The embodiment of the present application provides a clothing processing device. The clothing processing device may be a clothes dryer or a washing machine with integrated clothes drying function, which is used to dry clothes, etc. After the wet clothes are dried by the clothing processing device, they can be worn immediately after drying, which greatly improves people's quality of life.

[0048] Please refer to Figures 1 to 3 The clothes treating device 100 includes a housing, a barrel assembly 50 , a drying channel shell 20 , a fan 70 , a heat pump system 30 and an inverter 40 .

[0049] The box body constitutes the outer shell of the clothes processing device 100, and can provide an installation base for the barrel assembly 50, the drying tunnel housing 20, the fan 70, the heat pump system 30 and other components, and play a protective role. At the same time, the surface of the box body also constitutes the main appearance of the clothes processing device 100. The box body has a base 10, which is used to be supported on the ground or the installation surface. The barrel assembly 50, the drying tunnel housing 20, the fan 70, the heat pump system 30 and the inverter 40 are all arranged on the base 10.

[0050] The barrel assembly 50 is a structure in the clothing processing device 100 mainly used to provide clothing processing functions. The barrel assembly 50 defines a clothing processing chamber and a loading port connected to the clothing processing chamber. Clothes can be put into the clothing processing chamber through the loading port, or taken out of the clothing processing chamber through the loading port.

[0051] The drying channel shell 20 is connected to the base 10, and together with the base 10, defines a drying channel 60 and a first air outlet and a second air outlet connecting the drying channel 60 and the clothing processing chamber. It can be understood that the gas can flow into the clothing processing chamber through the drying channel 60 to dry the clothing. The drying channel shell 20 is made of metal or other high-temperature resistant materials to have sufficient strength and good tolerance to high-temperature airflow, thereby improving the service life of the drying channel shell 20. Of course, the drying channel shell 20 can also be connected to the base 10, and define the drying channel 60 and the first air outlet and the second air outlet by 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 in the drying tunnel 60 and is connected to the output end of the motor 71 so as to rotate under the drive of the motor 71. The rotating impeller 72 drives the airflow into the clothing processing chamber through the first air port, and after processing the clothing, the airflow flows into the drying tunnel 60 from the second air port. Optionally, the first air port is disposed near the bottom of the clothing processing chamber, and the second air port is disposed near the loading port.

[0053] The heat pump system 30 can form a refrigerant cycle and is used to heat the airflow flowing through the drying tunnel 60. The heat pump system 30 includes a compressor 31, a condenser 33, and an evaporator 32. The compressor 31, the condenser 33, and the evaporator 32 are all arranged on the base 10, and along the flow direction of the airflow in the drying tunnel 60 (from the second air outlet to the first air outlet), the evaporator 32 and the condenser 33 are arranged in sequence. It can be understood that the compressor 31, the condenser 33 and the evaporator 32 are connected through the refrigerant pipeline. The specific principle is: the compressor 31 sucks in low-pressure gaseous refrigerant, which is compressed by the compressor 31 and discharged at high pressure. The discharged high-pressure refrigerant enters the condenser 33, is cooled by the air at room temperature, and condenses into high-pressure liquid (while transferring heat to the surrounding air); the high-pressure liquid refrigerant flows through the expansion valve 34, throttling and reducing pressure, and becomes a low-pressure and low-temperature gas-liquid two-phase mixture and enters the evaporator 32. The liquid refrigerant evaporates and refrigerates in the evaporator 32 (while absorbing heat from the surrounding air), and the low-pressure gaseous refrigerant generated is sucked in by the compressor 31 again and pressurized, and this cycle repeats continuously to achieve heat exchange.

[0054] Therefore, the working process of the clothing treatment device 100 during the clothing drying operation is as follows: the condenser 33 heats the airflow in the drying tunnel 60 to generate high-temperature dry air at about 40°C & 65°C, and the dry air enters the clothing treatment chamber through the first air outlet; in the clothing treatment chamber, the dry air flows through the surface of the wet clothes, exchanges heat and moisture with the wet clothes, absorbs moisture in the clothes, and becomes high-temperature and high-humidity gas. The high-temperature and high-humidity gas is discharged from the clothing treatment chamber through the second air outlet, and then passes through the evaporator 32, and the high-temperature and high-humidity air is cooled to become low-temperature and low-humidity gas, which flows to the condenser 33. Such a cycle operation realizes continuous and efficient drying of clothes.

[0055] Optionally, the inverter 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 the related art, the inverter 40 is usually fixed on the base 10, and due to the large size of the inverter 40, there are problems of high cost and space occupation.

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

[0057] The cover shell 41 is disposed on the drying tunnel shell 20, and defines a mounting cavity together with the drying tunnel shell 20. The frequency conversion control board 42 is disposed in the accommodating cavity and is electrically connected to the compressor 31 to control the rotation speed of the compressor 31. The cover shell 41 can be made of plastic or alloy. When plastic is used, it has the advantages of convenient manufacturing and light structure. When alloy is used, it can better ensure structural strength and good heat dissipation performance. Specifically, the cover shell 41 forms a groove structure, and the side of the cover shell 41 with the notch is connected to the drying tunnel shell 20, so that the drying tunnel shell 20 and the cover shell 41 define the above-mentioned accommodating cavity together.

[0058] It should be noted that in the embodiment where the laundry treatment device 100 includes a main control board, the frequency conversion control board 42 is different from the main control board. The main control board is used to control the operation of the whole machine, while the frequency conversion control board 42 is used to control the frequency conversion of the compressor 31. Optionally, the main control board and the frequency conversion control board 42 can be integrated or separately arranged.

[0059] It can be understood that the embodiment of the present application forms a receiving cavity for setting the frequency conversion control board 42 by placing the cover shell 41 on the drying tunnel shell 20 to enclose together, so that the drying tunnel shell 20 forms a partial shell of the frequency converter 40, and the drying tunnel shell 20 is used to form the drying tunnel 60 and also used to cover and protect the frequency conversion control board 42 together with the cover shell 41. Compared with the related art, the frequency converter 40 in the technical solution of the embodiment of the present application uses the drying tunnel shell 20 as a part of the shell, which can not only reduce the materials originally used to form the shell of the frequency converter 40, reduce the complexity of the cover shell 41, and save costs, but also because of the reduction of materials, the space occupied by the frequency converter 40 in the clothing processing device 100 is also reduced, the structure is more compact, and the space utilization rate is improved.

[0060] Combination Figure 3In some embodiments, the drying channel shell 20 includes a top shell 21 and a side shell 22, and the side shell 22 is connected between the top shell 21 and the base 10 to enclose the drying channel 60 together. Taking the horizontal placement of the clothing processing device 100 as an example, the loading port faces one side in the horizontal direction, the base 10 is placed on the ground, and the side shell 22 is connected to the base 10 and extends in the up and down direction. The top shell 21 is arranged at one 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 are enclosed together to form the drying channel 60. Among them, the side shell 22 and the base 10 can be connected by one or more of the connection methods such as bolt connection and snap connection, which is not limited in this embodiment. The top shell 21 and the side shell 22 can be an integrated structure with good structural integrity; or the top shell 21 and the side shell 22 can be formed separately and connected by one or more of the connection methods such as bolt connection or snap connection, which is convenient for assembly. In an embodiment where the top shell 21 and the side shell 22 are formed separately, the top shell 21 and the side shell 22 can be made of the same or different materials, for example, the top shell 21 is made of plastic and the side shell 22 is made of metal, etc., which is not limited in this embodiment of the present application.

[0061] In one embodiment, the cover 41 is disposed on the top shell 21. Since the inverter 40 in the related art is disposed on the base 10, and various components of the clothing treatment device 100 are integrated on the base 10, the structure is relatively complex, the space is cramped, and it is not convenient to arrange the structure. In the embodiment of the present application, the cover 41 is disposed on the top shell 21, so that the overall structure of the inverter 40 is away from the base 10. On the one hand, it can reduce the space occupied by the base 10 and facilitate the arrangement of various components on the base 10. On the other hand, it is disposed on the top shell 21 to utilize the space near the top shell 21 in the box of the clothing treatment device 100, thereby improving the space utilization rate.

[0062] In another embodiment, the cover 41 can also be arranged on the side shell 22, which can also make the overall structure of the inverter 40 away from the base 10, reduce the space occupied by the base 10, facilitate the layout of various components on the base 10, and utilize the space near the side shell 22 in the box of the clothing processing device 100 to improve space utilization. In addition, when the cover 41 is arranged in the side shell 22, the base 10 can be removed to expose the cover 41 through the drying channel 60 space left by the base 10. When the cover 41 is arranged outside the side shell 22, the side plate of the box that blocks the side shell 22 can be removed to expose the cover 41; this can facilitate the staff to inspect and repair the inverter 40 and improve work efficiency.

[0063] Of course, in one embodiment, the cover 41 may also cover the top shell 21 and the side shell 22. For some inverters 40 with complex structures and larger volumes, part of the cover 41 is covered on the top shell 21, and the other part is covered on the side shell 22, so that the space near the top shell 21 and the side shell 22 is utilized to increase the spreading area of ​​the inverter 40, reduce the thickness of the cover 41, avoid interference of the cover 41 with other devices, and improve space utilization.

[0064] Combine the following Figure 3 as well as Figures 5 to 8 , the explanation will be continued by taking the case where the cover shell 41 is covered on the top shell 21 as an example.

[0065] In one embodiment, the cover 41 is connected to the outer surface of the top shell 21. Figure 1 As shown, the barrel assembly 50 is mounted above the drying tunnel shell 20, and there is a part of space between the barrel assembly 50 and the top shell 21. The cover shell 41 is set outside the top shell 21 so that the cover shell 41 is located between the top shell 21 and the barrel assembly 50, so that this part of space can be utilized, thereby improving the space utilization rate and making the structure more compact. In addition, the cover shell 41 is set outside the top shell 21 so that the frequency conversion control board 42 can be exposed to the drying tunnel 60 as little as possible, avoiding the frequency conversion control board 42 from being affected by moisture, and the cover shell 41 and the frequency conversion control board 42 can be set outside the top shell 21 after the top shell 21, the side shell 22 and the base 10 are assembled, so that the disassembly and assembly are convenient.

[0066] Combination Figure 5 and Figure 6 In one embodiment, the drying tunnel shell 20 is provided with a connecting port 20a, and the cover shell 41 covers the connecting port 20a. The shape of the connecting port 20a can be circular or square, etc., which is not limited here. The connecting port 20a connects the installation cavity and the drying tunnel 60, and the connecting port 20a is located on the upstream side of the condenser 33. The frequency conversion control board 42 is provided with a frequency conversion chip for controlling the compressor 31. In actual use, the frequency conversion chip and other components will generate heat. As mentioned above, the airflow in the drying tunnel 60 is heated when passing through the condenser 33. Compared with the airflow downstream of the condenser 33, the airflow temperature on the upstream side of the condenser 33 is lower. Under the premise that the frequency conversion control board 42 is well waterproofed, the airflow on the upstream side of the condenser 33 can flow into the installation cavity through the connecting port 20a to take away the heat emitted by the frequency conversion control board 42 when it is working, so as to achieve heat dissipation of the frequency conversion control board 42.

[0067] In order to improve the heat dissipation effect of the frequency conversion 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, one or more of silver, copper, and aluminum. It should be noted that the heat sink 43 can be made of pure metal or alloy. Figure 6As shown, the heat sink 43 is connected to the frequency conversion control board 42, and the heat sink 43 is arranged through the communication port 20a and is partially located in the drying tunnel 60. In this way, the heat of the frequency conversion control board 42 is transferred to the heat sink 43, and the airflow in the drying tunnel 60 can exchange heat with the heat sink 43 when passing through the heat sink 43, thereby achieving heat dissipation of the frequency conversion control board 42.

[0068] Furthermore, the heat sink 43 includes a heat sink substrate 431 and a plurality of heat sink fins 432 arranged at intervals on one side of the heat sink substrate 431. The heat sink substrate 431 is connected to the frequency conversion control board 42, and the heat sink substrate 431 blocks the connecting port 20a, so as to prevent the airflow in the drying tunnel 60 from entering the inside of the cover 41 through the connecting port 20a and affecting the frequency conversion control board 42. A plurality of heat sink fins 432 are located in the drying tunnel 60, and a flow passage is formed between two adjacent heat sink fins 432, and the flow passage is conducted in the direction of the airflow in the drying tunnel 60, so that a plurality of heat sink fins 432 are provided to increase the contact area with the airflow in the drying tunnel 60, so as to further improve the cooling effect of the heat sink 43.

[0069] Furthermore, the extension direction of the flow channel is parallel to the flow direction of the airflow in the drying tunnel 60. This layout ensures that the airflow in the drying tunnel 60 can flow directly and smoothly through the flow channel without being blocked by any obstacles. When the airflow in the drying tunnel 60 flows through the flow channel, it can not only quickly take away the heat on the heat dissipation fins 432 and reduce the temperature of the frequency conversion control board 42, but also maintain its original flow speed. This design ensures that the airflow in the drying tunnel 60 will not slow down when flowing through the heat dissipation fins 432, thereby ensuring that the heat in the drying tunnel 60 is evenly distributed and can be effectively transferred to the clothes, thereby improving the drying efficiency.

[0070] Combination Figure 5 and Figure 6 In one embodiment, the communication port 20a is disposed between the evaporator 32 and the condenser 33, and the portion of the heat sink 43 located in the drying tunnel 60 is also disposed between the evaporator 32 and the condenser 33. It can be understood that the temperature of the airflow in the drying tunnel 60 decreases after passing through the evaporator 32, and the low-temperature airflow can fully exchange heat with the heat sink 43 when passing through the heat sink 43, taking away more heat, and further improving the heat dissipation effect.

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

[0072] Combination Figure 6In one embodiment, the clothing processing device 100 further includes a first sealing member 44, which is arranged along the circumference of the communication port 20a to seal the gap between the heat sink 43 and the wall of the communication port 20a. Optionally, the first sealing member 44 may be a high temperature resistant sealant, which fills the gap between the heat sink 43 and the wall of the communication port 20a; or, the first sealing member 44 may also be a sealing ring, which is arranged in an annular shape and sleeved on the heat sink 43 to fill the gap between the heat sink 43 and the wall of the communication port 20a, and the sealing ring is made of a high temperature resistant rubber material to achieve a better filling effect. Accordingly, the shape of the communication port 20a may be adapted to the shape of the heat sink 43, for example, the heat sink 43 is cylindrical and the communication port 20a is circular; or the heat sink 43 is prismatic and the communication port 20a is rectangular. The matching of the shapes of the communication port 20a and the heat sink 43 can make the first sealing member 44 around the heat sink 43 more uniform and improve the sealing effect. Thus, in the embodiment of the present application, the first sealing member 44 is provided to seal the communication port 20 a , thereby isolating the airflow in the drying tunnel 60 , preventing the frequency conversion control board 42 from being affected by moisture in the drying tunnel 60 , and improving the reliability of the frequency converter 40 .

[0073] Of course, the heat sink 43 may also be completely located in the drying tunnel 60, and the first sealing member 44 is used to seal the communication port 20a.

[0074] like Figure 7 and Figure 8As shown, in some other embodiments, the cover 41 is connected to the inner surface of the drying tunnel shell 20, so that the frequency converter 40 uses the space in the drying tunnel 60, so that the overall structure of the frequency converter 40 is away from the base 10, reducing the space occupied by the base 10, and facilitating the layout of various components on the base 10. Optionally, the cover 41 is provided with a connecting port 20a, the connecting port 20a connects the installation cavity and the drying tunnel 60, and is located on the upstream side of the condenser 33. The shape of the connecting port 20a can be circular or square, etc., which is not limited here. In the embodiment where the heat sink 43 is not provided at the connecting port 20a, under the premise that the frequency conversion control board 42 is well waterproofed, the airflow on the upstream side of the condenser 33 can flow into the installation cavity through the connecting port 20a to take away the heat emitted by the frequency conversion control board 42 when working, so as to achieve heat dissipation of the frequency conversion control board 42. Further, the heat sink 43 is connected to the frequency conversion control board 42, and the heat sink 43 is penetrated through the connecting port 20a and is partially located in the drying tunnel 60. The specific material and structure of the heat sink 43 are as described above, and will not be elaborated here. In this way, the heat of the frequency conversion control board 42 is transferred to the heat sink 43, and the airflow in the drying tunnel 60 can exchange heat with the heat sink 43 when passing through the heat sink 43, thereby achieving heat dissipation of the frequency conversion control board 42. Among them, the cover 41 is arranged between the evaporator 32 and the condenser 33, or the connecting port 20a on the cover 41 is arranged between the evaporator 32 and the condenser 33, and the part of the heat sink 43 located in the drying tunnel 60 is also arranged between the evaporator 32 and the condenser 33, further improving the heat dissipation effect. The first sealing member 44 is arranged along the circumference of the connecting port 20a to seal the gap between the heat sink 43 and the connecting port 20a, to prevent the frequency conversion control board 42 from being affected by the moisture in the drying tunnel 60, and to improve the reliability of the frequency converter 40.

[0075] Reference Figure 6 and Figure 8 In order to further improve the sealing performance of the inverter 40, the clothing processing device 100 further includes a second sealing member 45 and a third sealing member.
