[0046] In daily life, most clothes treatment devices (dryers, washer-dryer) have a drying function. After the wet clothes are dried by the clothes treatment device, the clothes can be worn immediately, greatly improving the quality of people's life.

[0047] With reference to Figures 1 to 3 The clothes treatment device 100 can be a washing machine, a dryer, a washer-dryer, etc., and is used to perform washing, dehydration and other operations on various types of clothes. In the embodiments of the present application, the clothes treatment device 100 includes a cabinet, a tub assembly 50, a drying duct shell 20, a fan 70, a heat pump system 30 and a frequency converter 40.

[0048] The cabinet constitutes the shell part of the clothes treatment device 100, and can provide a mounting base for the tub assembly 50, the drying duct shell 20, the fan 70 and the heat pump system 30, etc., and plays a protection role. At the same time, the surface of the cabinet also constitutes the main appearance surface of the clothes treatment device 100. The cabinet has a base 10 for supporting on the ground or mounting surface, and the tub assembly 50, the drying duct shell 20, the fan 70 and the heat pump system 30 are all arranged on the base 10.

[0049] The tub assembly 50 is a structure mainly used to provide clothes treatment functions in the clothes treatment device 100, and defines a clothes treatment cavity and a drop opening communicating with the clothes treatment cavity. Clothes can be put into the clothes treatment cavity through the drop opening, or taken out of the clothes treatment cavity through the drop opening.

[0050] The drying duct shell 20 is connected with the base 10 and cooperates with the base 10 to define a drying duct 60 and first and second air inlets communicating the drying duct 60 and the clothes treatment cavity. It should be noted that the drying duct 60 can also be formed directly by the drying duct shell 20 itself, so as to facilitate the control of the specific shape of the drying duct 60. Understandably, gas can flow into the clothes treatment cavity through the drying duct 60 to perform drying treatment on the clothes. The drying duct shell 20 is made of metal or other materials resistant to high temperature, so as to have sufficient strength and good resistance to high-temperature gas flow, improving the service life of the drying duct shell 20.

[0051] The fan 70 is connected to the base 10 and includes a motor 71 and an impeller 72. The impeller 72 is arranged in the drying channel 60 and is connected to the output end of the motor 71 to rotate under the drive of the motor 71. The rotating impeller 72 drives the airflow to enter the clothes treatment cavity through the first air outlet and to flow into the drying channel 60 from the second air outlet after clothes treatment. Alternatively, the first air outlet is arranged close to the bottom of the clothes treatment cavity, and the second air outlet is arranged close to the drop-off opening.

[0052] The heat pump system 30 is capable of forming a refrigerant cycle and is used to heat the airflow flowing through the drying channel 60. The heat pump system 30 includes a compressor 31, a condenser 33, an evaporator 32, and an expansion valve. The compressor 31, the condenser 33, the expansion valve, and the evaporator 32 are sequentially and serially arranged, and each of the compressor 31 and the condenser 33, the condenser 33 and the expansion valve, and the expansion valve and the evaporator 32 is connected by a corresponding refrigerant pipeline. The specific type of refrigerant is not limited and can be selected and determined according to the actual use condition. It should be noted that in another embodiment, the expansion valve in the above can be a capillary tube. The compressor 31, the condenser 33, and the evaporator 32 are all arranged in the base 10, and the evaporator 32 and the condenser 33 are sequentially and spaced apart along the flow direction of the airflow in the drying channel 60 (from the second air outlet to the first air outlet).

[0053] The working principle of the heat pump system 30 is as follows: the compressor 31 sucks in low-pressure gaseous refrigerant, which is discharged at high pressure after being compressed by the compressor 31. The high-pressure refrigerant enters the condenser 33 and is cooled by the air at room temperature, and is condensed into high-pressure liquid (at the same time, heat is transferred to the surrounding air). The high-pressure liquid refrigerant flows through the expansion valve to be throttled and decompressed, and then becomes a low-pressure low-temperature gas-liquid two-phase mixture, which enters the evaporator 32. The liquid refrigerant in the evaporator 32 evaporates and cools (at the same time, absorbs heat from the surrounding air), and the generated low-pressure gaseous refrigerant is again sucked into the compressor 31 for pressurization, and the cycle is repeated. Heat exchange is achieved.

[0054] Therefore, the working process of the clothes treatment device 100 during the clothes drying operation is as follows: the condenser 33 heats the airflow in the drying channel 60 to generate high-temperature dry air at about 40-65°C, and the dry air enters the clothes treatment cavity through the first air outlet; in the clothes treatment cavity, the dry air flows through the surface of the wet clothes and exchanges heat and moisture with the wet clothes, absorbs the moisture in the clothes, and becomes high-temperature and high-humidity gas. The high-temperature and high-humidity gas is discharged from the clothes treatment cavity 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, and flows to the condenser 33. Such a cycle is repeatedly performed to achieve continuous and efficient drying of the clothes.

[0055] The temperature and humidity of the air is reduced and dehumidified in the evaporator 32 by cold and heat exchange of the refrigerant, and the circulation of the refrigerant in the closed loop refrigerant circuit is realized by the operation of the compressor 31. In the embodiment of the present application, the frequency converter 40 is electrically connected with the compressor 31 of the heat pump system 30, and the frequency converter 40 can control the working frequency of the compressor 31, and the compressor 31 works at different working frequencies in different stages. That is, the frequency of the compressor 31 can be adjusted, and when the frequency converter 40 adjusts the frequency of the compressor 31, the refrigerant flow in the system and the working time of the compressor 31 can be adjusted, thereby affecting the working conditions of the evaporator 32 and the condenser 33. For example, when more cooling capacity is needed, the frequency converter 40 will increase the frequency of the compressor 31, resulting in more refrigerant being compressed and delivered to the evaporator 32, thereby enhancing the refrigeration effect of the evaporator 32. Conversely, when power consumption needs to be reduced or low load demand is met, the frequency control board 42 will reduce the frequency of the compressor 31, reduce the refrigerant flow, and reduce the running time of the system to achieve the purpose of energy saving. It should be noted that the frequency converter 40 of the present application can also be electrically connected with the fan 70 for controlling the output power of the fan 70.

[0056] In the related art, due to the volume limitation of the clothes treatment device, the heat dissipation area of the frequency converter is relatively limited, which causes the temperature inside the frequency converter to rise rapidly when the power output is high. The excessively high temperature not only affects the normal operation and stability of the frequency converter, but also accelerates the aging of the internal components, thereby shortening the service life.

[0057] Reference Figure 3 To solve the above problems, the frequency converter 40 of the present application includes a housing 41, a frequency control board 42, and a heat dissipation member 43.

[0058] The housing 41 can be fixed to the drying duct shell 20 or the base 10, of course, the housing 41 can be fixed to the drying duct shell 20 and the base 10 at the same time. The housing 41 can be made of non-metallic materials such as plastic materials, which are lighter than metal materials, and can effectively reduce the overall weight of the frequency converter 40, making installation and operation more convenient.

[0059] The frequency control board 42 is arranged in the housing 41, specifically, the frequency control board 42 can be connected to the inner wall of the housing 41 by adhesion or screws. The frequency control board 42 can be a PCBA (Printed Circuit Board Assembly). Due to the use of PCBA technology, the electronic components on the frequency control board 42 can be highly integrated, thereby reducing the volume and weight of the board, and improving the overall reliability.

[0060] The mounting layout of the heat dissipation member 43 can take various forms to ensure effective heat dissipation. One way is to directly and tightly fix the heat dissipation member 43 with the frequency conversion control panel 42, and part of the heat dissipation member 43 extends out of the shell 41, so that the heat dissipation member 43 can directly enter the drying channel 60. Through this design, the heat generated on the frequency conversion control panel 42 can be directly conducted to the heat dissipation member 43, and then dissipated through the surface of the heat dissipation member 43. Another design is to fix the heat dissipation member 43 on the shell 41, for example, directly fixed on the outer surface of the shell 41, and part of it extends into the drying channel 60. In this way, the heat on the frequency conversion control panel 42 will first be conducted to the shell 41, and then conducted to the heat dissipation member 43 through the shell 41, and finally achieve the effect of heat dissipation.

[0061] Of course, in order to further improve the heat dissipation efficiency, the heat dissipation member 43 can also be connected to the frequency conversion control panel 42 and the shell 41 at the same time. In this layout, the heat dissipation member 43 can be in contact with the frequency conversion control panel 42 and the shell 41 respectively, forming a heat conduction bridge. In this way, whether it is the heat generated by the frequency conversion control panel 42 or the heat conducted through the shell 41, it can be quickly transferred to the heat dissipation member 43 and exchanged with the airflow in the drying channel 60 through the heat dissipation member 43, thereby achieving more efficient heat dissipation.

[0062] The specific material of the heat dissipation member 43 is not limited, as long as it has good heat conduction performance, for example, one or more of silver, copper, and aluminum. It should be noted that the heat dissipation member 43 can be made of pure metal or alloy.

[0063] The clothes treatment device 100 of the embodiment of the present application, the heat of the frequency conversion control panel 42 of the frequency converter 40 is conducted to the heat dissipation member 43 for heat dissipation, and at the same time, the heat dissipation member 43 is at least partially located in the drying channel 60 formed by the drying channel shell 20, so that the heat on the heat dissipation member 43 can be taken away by the airflow in the drying channel 60, and the temperature of the heat dissipation member 43 is quickly reduced. Therefore, even at high power output, the temperature rising speed of the frequency conversion control panel 42 can be effectively slowed down. In this way, not only the heat dissipation condition of the frequency converter 40 is effectively improved, but also the heat dissipation member 43 can be cooled without additional cooling fans, reducing the additional power consumption of the clothes treatment device 100, thereby improving the energy efficiency, simplifying the internal structure of the clothes treatment device 100, reducing the cost, and making the structure of the clothes treatment device 100 more compact. The compact structure design also makes the clothes treatment device 100 more beautiful in appearance and occupies less space, which is convenient for flexible layout and use.

[0064] Reference Figure 3Optionally, the heat dissipation member 43 is located on the upstream side of the condenser 33 along the flow direction of the airflow in the drying channel 60. Since the airflow in the drying channel 60 will be converted into high-temperature and high-humidity gas after passing through the condenser 33, the layout of placing the heat dissipation member 43 on the upstream side of the condenser 33 is more conducive to cooling the heat dissipation member 43. Specifically, when the airflow has not passed through the condenser 33, the temperature and humidity of the airflow are relatively low, which can effectively cool the heat dissipation member 43 located in the drying channel 60, thereby achieving efficient heat dissipation. Thus, the heat dissipation member 43 is arranged on the upstream side of the condenser 33, which is more conducive to cooling the heat dissipation member 43. At the same time, since the heat dissipation member 43 dissipates part of the heat to the airflow in advance, the temperature of the airflow will correspondingly decrease when the airflow passes through the condenser 33, which helps to reduce the burden of the condenser 33, improve the overall efficiency of the system, and reduce the energy consumption and cost in the processing process.

[0065] Further, the heat dissipation member 43 is located between the condenser 33 and the evaporator 32 along the flow direction of the airflow in the drying channel 60. In this layout, the heat dissipation member 43 is located after the evaporator 32 and before the condenser 33, and the airflow after passing through the evaporator 32 is low-temperature and low-humidity gas. Since the function of the evaporator 32 is to cool the high-temperature gas into low-temperature and low-humidity gas, the temperature of the airflow after passing through the evaporator 32 is low, and the humidity is small. When such low-temperature and low-humidity airflow passes through the heat dissipation member 43, the cooling effect of the heat dissipation member 43 can be further improved.

[0066] With reference to Figure 4 and Figure 5 In some structural forms, the drying channel shell 20 is provided with a communication port 20a penetrating the drying channel shell 20, so that the cover shell 41 is mounted on the outer surface of the drying channel shell 20 and covers the communication port 20a. The heat dissipation member 43 is partially or entirely located in the drying channel 60 through the communication port 20a. The communication port 20a can be a regular shape such as a circular port or a square port for easy processing, and the heat dissipation member 43 can pass through it. When the heat dissipation member 43 is only partially located in the drying channel 60, the hindering effect of the heat dissipation member 43 on the airflow in the drying channel 60 can be reduced to ensure the airflow speed in the drying channel 60, thereby ensuring the drying effect. When the heat dissipation member 43 is entirely located in the drying channel 60, the contact area with the airflow in the drying channel 60 can be further increased, thereby improving the cooling effect of the heat dissipation member 43.

[0067] Further, the cover shell 41 can jointly enclose the drying channel shell 20 to form a mounting cavity 20A, and the frequency conversion control panel 42 is mounted in the mounting cavity 20A. Thus, the drying channel shell 20 can be used to protect the frequency conversion control panel 42, and part of the cover shell 41 can be integrated into the drying channel shell 20, which can reduce the complexity and material use of the cover shell 41, thereby reducing the overall cost of the clothes processing device 100.

[0068] With reference toFigure 3 and Figure 6 Further, the heat dissipation member 43 comprises a heat dissipation base plate 431 and a plurality of heat dissipation fins 432 arranged at intervals on one side of the heat dissipation base plate 431. The heat dissipation base plate 431 can be connected to the cover 41 alone, or connected to the frequency conversion control panel 42 alone, or connected to both the cover 41 and the frequency conversion control panel 42. The heat dissipation base plate 431 blocks the communication port 20a, so that the airflow in the drying channel 60 cannot enter the cover 41 through the communication port 20a and affect the frequency conversion control panel 42. The plurality of heat dissipation fins 432 are arranged in the drying channel 60, and a flow passage 43a is formed between adjacent two heat dissipation fins 432. The flow passage 43a is open in the direction of the airflow in the drying channel 60. By arranging a plurality of heat dissipation fins 432, the contact area with the airflow in the drying channel 60 is increased, and the cooling effect of the heat dissipation member 43 is further improved.

[0069] Further, the extension direction of the flow passage 43a is parallel to the flow direction of the airflow in the drying channel 60. This arrangement ensures that the airflow in the drying channel 60 can flow directly and smoothly through the flow passage 43a without being hindered by any obstacles. When the airflow in the drying channel 60 flows through the flow passage 43a, it can not only quickly take away the heat on the heat dissipation fins 432 and reduce the temperature of the frequency conversion control panel 42, but also maintain its original flow speed. This design ensures that the airflow in the drying channel 60 does not slow down when flowing through the heat dissipation fins 432, thereby ensuring uniform heat distribution in the drying channel 60 and effectively transferring heat to the clothes, improving drying efficiency.

[0070] Referring to Figure 5Optionally, the frequency converter 40 further comprises a first seal 44, which is arranged between the opening wall of the communication opening 20a and the heat dissipation substrate 431 to seal the gap between the opening wall of the communication opening 20a and the heat dissipation substrate 431. The presence of the first seal 44 makes it difficult for the airflow in the drying channel 60 to enter the cover 41, thereby avoiding the potential impact of the airflow on the frequency conversion control panel 42. Such potential impact can include temperature changes, humidity changes, and the invasion of dust and impurities, which can threaten the stable operation of the frequency conversion control panel 42. The provision of the first seal 44 can provide a more stable and safe working environment for the frequency conversion control panel 42. During the operation of the clothes treatment device 100, the heat dissipation substrate 431 and the drying channel shell 20 can generate high temperatures, so the first seal 44 needs to be able to withstand these high-temperature environments without being damaged or failing. Secondly, the first seal 44 needs to have good elasticity and compressibility. This can ensure that the first seal 44 can tightly fit the opening wall of the communication opening 20a and the heat dissipation substrate 431 when filling the gap, forming an effective seal. At the same time, it also needs to be able to withstand compression and stretching without losing its sealing performance. The first seal 44 is made of a material that has excellent heat resistance and good elasticity and compressibility, such as silicone, fluororubber, and nitrile rubber. In addition, the frequency converter 40 further comprises a second seal 45, which is arranged between the cover 41 and the drying channel shell 20 to seal the gap between the cover 41 and the drying channel shell 20, thereby further improving the sealing of the installation cavity.

[0071] With reference to Figure 4 In some structural forms, the drying channel shell 20 comprises 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 jointly enclose the drying channel 60, and the cover 41 is mounted on the top shell 21 or the side shell 22. Among them, the top shell 21 and the side shell 22 can adopt an integrated structure, which can not only ensure the stability of the overall structure of the drying channel shell 20, but also simplify the assembly process and save time and labor costs. The cover 41 can be separately connected to the top shell 21 or the side shell 22, or the cover 41 can be connected to both the top shell 21 and the side shell 22. In this way, by mounting the cover 41 directly on the top shell 21 or the side shell 22, the space on the top shell 21 and the side shell 22 is utilized, avoiding the cover 41 directly occupying the installation position on the base 10. Such a design not only optimizes the spatial layout of the equipment, reduces the installation interference between the cover 41 and other components on the base 10, but also improves the overall aesthetics and practicality of the equipment.

[0072] Further, the cover 41 is connected to the outer surface of the top shell 21, so that the cover 41 can be directly disassembled from the outer surface of the top shell 21 after the subsequent maintenance process, reducing the number of disassembly of other components due to maintenance needs, saving maintenance time and labor cost, and improving the convenience of maintenance. Wherein, the cover 41 is located between the top shell 21 and the barrel assembly 50. Thus, the space between the top shell 21 and the barrel assembly 50 is utilized to further move away from other components on the base 10, thereby reducing the installation interference between the cover 41 and other components on the base 10, while making the internal structure of the clothes treatment device 100 more compact, and further improving the space utilization.

[0073] Referring to Figure 7 In another embodiment, the base 10 includes a bottom plate 11 and a side plate 12 detachably connected to the edge of the bottom plate 11, wherein the bottom plate 11 and the side plate 12 can be detachably connected by screws or buckles, etc. to ensure firm connection and convenient disassembly. The cover 41 is mounted on the outer surface of the side shell 22 and located between the side shell 22 and the side plate 12. Thus, after the subsequent maintenance process, the cover 41 can be directly exposed after the side plate 12 is disassembled, so that the cover 41 can be directly disassembled from the outer surface of the side shell 22 for maintenance, without having to disassemble the entire drying duct shell 20. Through such a design, not only the maintenance process is simplified, but also the difficulty and cost of maintenance are reduced, and the convenience of maintenance is improved.

[0074] Further, the cover 41 is connected to the side shell 22, and the side of the cover 41 away from the side shell 22 is provided in an open manner.
