Excessive temperature not only affects the normal operation and stability of the inverter, but also accelerates the aging of its internal components, thereby shortening its service life.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] In daily life, most clothing processing devices (dryers, integrated washer-dryers) have a clothes drying function. 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.

[0047] Reference Figures 1 to 3 The present application proposes a clothes processing device 100, which can be a washing machine, a dryer, a washer-dryer, etc., for washing and dehydrating various types of clothes. In an embodiment of the present application, the clothes processing device 100 includes a box, a barrel assembly 50, a drying channel shell 20, a fan 70, a heat pump system 30 and an inverter 40.

[0048] The housing constitutes the outer shell of the clothes processing device 100, and can provide a mounting base for the barrel assembly 50, the drying tunnel housing 20, the fan 70, and the heat pump system 30, and play a protective role. At the same time, the surface of the housing also constitutes the main appearance of the clothes processing device 100. The housing has a base 10, which is used to be supported on the ground or the mounting surface, and the barrel assembly 50, the drying tunnel housing 20, the fan 70, and the heat pump system 30 are all arranged on the base 10.

[0049] 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.

[0050] The drying channel shell 20 is connected to the base 10, and defines the drying channel 60 and the first and second air outlets connecting the drying channel 60 and the clothing processing chamber together with the base 10. It should be noted that the drying channel 60 can also be directly formed by the drying channel shell 20 itself, so as to facilitate the control of the specific shape of the drying channel 60. It can be understood that the gas can flow into the clothing processing chamber through the drying channel 60 to dry the clothes. 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.

[0051] 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.

[0052] 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, an evaporator 32 and an expansion valve. The compressor 31, the condenser 33, the expansion valve, and the evaporator 32 are arranged in series in sequence, and the compressor 31 and the condenser 33, the condenser 33 and the expansion valve, and the expansion valve and the evaporator 32 are each 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 conditions. It should be noted that, in another embodiment, the expansion valve mentioned above can be a capillary tube. 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.

[0053] The working principle of the heat pump system 30 is as follows: 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 to throttle and reduce pressure, and then becomes a low-pressure and low-temperature gas-liquid two-phase mixture and enters the evaporator 32, where the liquid refrigerant evaporates and cools 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 of 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] The cooling and dehumidification of the warm and humid gas in the evaporator 32 is achieved by heat exchange of the refrigerant, and the circulation of the refrigerant in the closed-loop refrigerant circuit is achieved by the operation of the compressor 31. In the embodiment of the present application, the inverter 40 is electrically connected to the compressor 31 of the heat pump system 30, and the inverter 40 can control the operating frequency of the compressor 31, and the compressor 31 is controlled to work at different operating frequencies at different stages. In other words, the frequency of the compressor 31 can be adjusted. When the inverter 40 adjusts the frequency of the compressor 31, the refrigerant flow rate 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 is needed, the inverter 40 will increase the frequency of the compressor 31, resulting in more refrigerant being compressed and transported to the evaporator 32, thereby enhancing the refrigeration effect of the evaporator 32. On the contrary, when it is necessary to reduce power consumption or adapt to low load requirements, the frequency conversion control board 42 will reduce the frequency of the compressor 31, reduce the refrigerant flow rate, and reduce the operating time of the system to achieve the purpose of energy saving. It should be noted that the frequency converter 40 of the present application may also be electrically connected to the fan 70 to control the output power of the fan 70 .

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

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

[0058] The cover 41 can be fixed to the oven housing 20 or to the base 10. Of course, the cover 41 can be fixed to both the oven housing 20 and the base 10. The cover 41 can be made of non-metallic materials such as plastic. Non-metallic materials such as plastic are lighter than metal materials, which can effectively reduce the overall weight of the inverter 40 and make installation and operation more convenient.

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

[0060] The installation layout of the heat sink 43 can take a variety of forms to ensure effective heat dissipation. One way is to directly and tightly fix the heat sink 43 to the frequency conversion control board 42, and part of the heat sink 43 extends out of the cover 41, so that the heat sink 43 can directly enter the drying tunnel 60. Through this design, the heat generated on the frequency conversion control board 42 can be directly conducted to the heat sink 43 and dissipated through the surface of the heat sink 43. Another design method is to fix the heat sink 43 to the cover 41, for example, directly fix it on the outer surface of the cover 41, and make part of it extend into the drying tunnel 60. In this way, the heat on the frequency conversion control board 42 will first be conducted to the cover 41, and then conducted from the cover 41 to the heat sink 43, and finally achieve the effect of heat dissipation.

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

[0062] 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.

[0063] In the clothing treatment device 100 of the embodiment of the present application, the heat of the frequency conversion control board 42 of the frequency converter 40 is transferred to the heat sink 43 for heat dissipation. At the same time, by locating the heat sink 43 at least partially in the drying tunnel 60 constructed by the drying tunnel shell 20, the heat on the heat sink 43 can be taken away by the airflow in the drying tunnel 60, and its temperature can be quickly reduced. Therefore, even at high power output, the temperature rise rate of the frequency conversion control board 42 can be effectively slowed down. In this way, not only the heat dissipation conditions of the frequency converter 40 are effectively improved, but also there is no need to set up an additional cooling fan to cool the heat sink 43, which reduces the additional power consumption of the clothing treatment device 100, thereby improving energy efficiency, and simplifying the internal structure of the clothing treatment device 100, reducing costs, making the structure of the clothing treatment device 100 more compact, and this compact structural design also makes the clothing treatment device 100 more beautiful in appearance, occupies less space, and is convenient for flexible layout and use.

[0064] Reference Figure 3Optionally, along the flow direction of the airflow in the drying tunnel 60, the heat sink 43 is located on the upstream side of the condenser 33. Since the airflow in the drying tunnel 60 will be converted into high-temperature and high-humidity gas after passing through the condenser 33, the heat sink 43 is placed on the upstream side of the condenser 33. Such a layout is more conducive to cooling the heat sink 43. Specifically, when the airflow has not passed through the condenser 33, its temperature and humidity are relatively low, which can effectively cool the heat sink 43 located in the drying tunnel 60, thereby achieving efficient heat dissipation. In this way, arranging the heat sink 43 on the upstream side of the condenser 33 is more conducive to cooling the heat sink 43. At the same time, since the heat sink 43 dissipates part of the heat into the airflow in advance, when the airflow passes through the condenser 33, its temperature rise will be reduced accordingly, which helps to reduce the burden on the condenser 33, improve the overall efficiency of the system, and reduce energy consumption and costs during the processing process.

[0065] Furthermore, along the flow direction of the airflow in the drying tunnel 60, the heat sink 43 is located between the condenser 33 and the evaporator 32. In such a layout, the heat sink 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 airflow after passing through the evaporator 32 has a lower temperature and lower humidity. When such a low-temperature and low-humidity airflow passes through the heat sink 43, the cooling effect on the heat sink 43 can be further improved.

[0066] Reference Figure 4 and Figure 5 In some structural forms, the drying tunnel shell 20 is provided with a connecting port 20a that penetrates the drying tunnel shell 20, so that when the cover shell 41 is installed on the outer surface of the drying tunnel shell 20 and covers the connecting port 20a. The heat sink 43 is partially or completely located in the drying tunnel 60 through the connecting port 20a. Among them, the connecting port 20a can be a regular shape such as a circular port or a square port for easy processing, and the heat sink 43 can pass through. When the heat sink 43 is only partially located in the drying tunnel 60, the obstruction effect of the heat sink 43 on the airflow in the drying tunnel 60 can be reduced, so as to ensure the airflow flow speed in the drying tunnel 60, and then ensure the drying effect. When the heat sink 43 is completely located in the drying tunnel 60, the contact area with the airflow in the drying tunnel 60 can be further increased, thereby improving the cooling effect of the heat sink 43.

[0067] Furthermore, the cover shell 41 can be together with the drying tunnel shell 20 to form an installation cavity 20A, and the frequency conversion control board 42 is installed in the installation cavity 20A. In this way, the drying tunnel shell 20 can be used to protect the frequency conversion control board 42. Integrating a part of the cover shell 41 into the drying tunnel shell 20 can reduce the complexity of the cover shell 41 and the use of materials, thereby reducing the overall cost of the clothing processing device 100.

[0068] Combined with reference Figure 3 and Figure 6 , further, 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 can be connected to the housing 41 alone or to the frequency conversion control board 42 alone, or even the heat sink substrate 431 can be connected to the housing 41 and the frequency conversion control board 42 at the same time. The heat sink substrate 431 blocks the connecting port 20a, so as to reduce the airflow in the drying tunnel 60 from entering the housing 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 43a is formed between two adjacent heat sink fins 432. The flow passage 43a is conducted in the direction of the airflow in the drying tunnel 60. In this way, 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 43a 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 43a without being blocked by any obstacles. When the airflow in the drying tunnel 60 flows through the flow channel 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 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] Reference Figure 5Optionally, the frequency converter 40 further includes a first seal 44, which is disposed between the mouth wall of the communication port 20a and the heat dissipation substrate 431 to seal the gap between the mouth wall of the communication port 20a and the heat dissipation substrate 431. The presence of the first seal 44 prevents the airflow in the drying tunnel 60 from easily invading the cover 41, thereby avoiding the potential impact of the airflow on the frequency conversion control board 42. Such potential impacts may include temperature changes, humidity changes, and the intrusion of dust and impurities, all of which may threaten the stable operation of the frequency conversion control board 42. The provision of the first seal 44 can provide a more stable and safe working environment for the frequency conversion control board 42. During the operation of the clothing processing device 100, the heat dissipation substrate 431 and the drying tunnel shell 20 may generate higher 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 ensures that the first seal 44 can fit closely to the mouth wall of the communication port 20a and the heat dissipation substrate 431 when filling the gap to form an effective seal. At the same time, it also needs to be able to withstand compression and stretching without losing sealing performance. The first sealing member 44 is made of a material with excellent heat resistance, good elasticity and compressibility, such as silicone, fluororubber, nitrile rubber, etc. In addition, the inverter 40 also includes a second sealing member 45, which is arranged between the cover 41 and the drying tunnel shell 20 to seal the gap between the cover 41 and the drying tunnel shell 20, so as to further improve the sealing of the installation cavity.

[0071] Reference Figure 4 In some structural forms, 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 enclose the drying tunnel 60 together, and the cover shell 41 is installed 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 tunnel shell 20, but also simplify the assembly process and save time and labor costs. The cover shell 41 can be connected to the top shell 21 alone, or to the side shell 22 alone, or even to the top shell 21 and the side shell 22 at the same time. In this way, by directly installing the cover shell 41 on the top shell 21 or the side shell 22, the space on the top shell 21 and the side shell 22 is utilized, and the cover shell 41 is avoided from 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 shell 41 and other components on the base 10, but also improves the overall aesthetics and practicality of the equipment.

[0072] Furthermore, the cover 41 is connected to the outer surface of the top shell 21, so that the cover 41 can be directly removed from the outer surface of the top shell 21 after the subsequent maintenance process, reducing the number of times other components are removed due to maintenance needs, saving maintenance time and labor costs, and improving the convenience of maintenance. Among them, 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 stay away from other components on the base 10, thereby reducing the installation interference between the cover 41 and other components on the base 10, and at the same time making the internal structure of the clothing processing device 100 more compact, further improving the space utilization.

[0073] Reference 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 means of screws or buckles to ensure a firm connection and convenient disassembly. The cover shell 41 is installed on the outer surface of the side shell 22 and is located between the side shell 22 and the side plate 12. In this way, after the side plate 12 is removed during the subsequent maintenance process, the cover shell 41 can be directly exposed, so that the cover shell 41 can be directly removed from the outer surface of the side shell 22 for maintenance without having to disassemble the entire oven 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.
