Moisture generated during operation or heat generated by internal electrical components can be discharged to the external environment through this connection port. However, with this type of dryer, noise generated by internal electrical components (such as the compressor and motor) also leaks to the external environment through the connection port, increasing the dryer's operating noise and affecting the user experience.

The space between two adjacent partitions forms the noise reduction cavity. The ends of two adjacent partitions near the through hole are spaced apart and define the communication port. The communication port and the noise reduction cavity together form a quarter-wavelength tube structure.
[0014] In some implementations, at least two of the noise-reducing cavities have different radial lengths in the disk portion.
[0015] In some implementations, the length of the noise reduction cavity increases sequentially over at least a portion of the circumference of the disk.
[0016] In some embodiments, in a plane projection perpendicular to the height direction of the base device, the projections of the ends of each partition closest to the through hole are located on the same circumference, while the projections of the ends of each partition furthest from the through hole are located on different circumferences.
[0017] In some implementations, the first noise reduction structure further includes a connecting ear connected to the circumferential outer side of the disk portion, and the base device includes one or more connectors connecting the connecting ear to the base.
[0018] In some embodiments, the at least one noise reduction structure includes a second noise reduction structure, and the at least one ventilation hole includes a second ventilation hole;

Therefore, they should not be construed as limitations on the embodiments of this application.
[0041] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0042] This application provides a base device 1.
[0043] It should be noted that the application scenarios of the base device 1 are not limited. In this embodiment of the application, the base device 1 is used as an example for describing clothing processing equipment.
[0044] This application provides a garment processing device, including a bobbin assembly, a power mechanism, and a base device 1 according to any embodiment of this application.
[0045] It is understood that the specific form of the garment processing equipment is not limited; for example, the garment processing equipment can at least be used to dry clothes. The garment processing equipment can be a dryer, a washer-dryer combo, etc.
[0046] The tube assembly has a clothing handling chamber.
[0047] The specific construction of the drum assembly is not limited. Exemplarily, the drum assembly may include an inner drum and an outer drum, with the outer drum fitted over the inner drum. The outer drum holds water for washing clothes, and the inner drum holds the clothes. The space within the inner drum defines a clothes handling chamber. Exemplarily, the inner and outer drums are arranged coaxially, with holes on the side wall of the inner drum. Water from the outer drum can enter the inner drum through these holes to wash the clothes in the clothes handling chamber. In this embodiment, the inner drum may also be referred to as a perforated inner drum. In other embodiments, the inner drum may be referred to as a non-perforated inner drum. Of course, in still some embodiments, the drum assembly may only include an inner drum, which holds water and clothes on its own.
[0048] Please see Figures 1 to 2 The base device 1 includes a base 10 and at least one noise reduction structure 11.
[0049] The base 10 can be located below the cylinder assembly, that is, the base 10 can be located in the bottom space of the garment processing equipment.
[0050] The base 10 includes an air duct 10a and a power mechanism mounting area 10b located outside the air duct 10a. The power mechanism is located in the power mechanism mounting area 10b.
[0051] The air duct 10a is connected to the garment processing chamber. Specifically, the air duct 10a is used to allow airflow, which can circulate between the air duct 10a and the garment processing chamber to dry the garments.
[0052] The power mechanism installation area 10b is located outside the air duct 10a. In other words, the power mechanism is located outside the air duct 10a, which facilitates the air circulation around the power mechanism during operation, enhances the heat dissipation effect, and reduces the impact of the heat generated by the power mechanism during operation on the heat exchange components inside the air duct 10a. At the same time, it also facilitates the disassembly and maintenance of the power mechanism without affecting the structure inside the air duct 10a.
[0053] In some embodiments, the power mechanism includes an electric motor 3 and / or a compressor 2.
[0054] Compressor 2 is used to compress refrigerant. Compressor 2 has an intake port and an exhaust port. Compressor 2 draws in refrigerant with a lower temperature and lower pressure from the intake port, and the piston is driven by motor 3 to compress the refrigerant. The refrigerant with increased temperature and pressure is output from the exhaust port.
[0055] It is understandable that refrigerant, also known as coolant or refrigerant, is a medium used to complete the heat exchange cycle.
[0056] For example, the garment handling equipment includes a heat exchange assembly comprising an evaporator and a condenser, which are disposed within an air duct 10a. The evaporator is positioned upstream of the condenser along the airflow direction. The evaporator condenses and dehumidifies the airflow, while the condenser heats the airflow. The compressor 2, the evaporator, and the condenser are connected via a refrigerant circulation pipeline to form a refrigerant circulation loop.
[0057] The following is a brief explanation of the drying process and principle of clothing processing equipment.
[0058] When drying clothes, the dry hot airflow in the air duct 10a enters the clothes processing chamber through the air duct 10a. After exchanging heat and moisture with the clothes in the clothes processing chamber, it becomes a humid hot airflow. The humid hot airflow flows through the evaporator, where the refrigerant absorbs heat and lowers the temperature, turning it into a low-temperature dry airflow. The low-temperature dry airflow absorbs heat from the refrigerant at the condenser and rises in temperature, turning into a dry hot airflow, which then exchanges heat with the clothes again. This cycle continues to achieve continuous and efficient drying of clothes.
[0059] It should be noted that the low-temperature dry airflow is relative to the humid and hot airflow, and the temperature of the low-temperature dry airflow is lower than that of the humid and hot airflow. In the embodiments of this application, the low temperature can be room temperature.
[0060] Please see Figure 1 The power mechanism mounting area 10b is provided with at least one ventilation hole 10e. At least one noise reduction structure 11 is provided around the ventilation hole 10e.
[0061] It is understandable that clothing processing equipment generates a significant amount of moisture when performing the drying function. This embodiment includes a ventilation hole 10e, which connects to the external environment, allowing moisture to escape to the outside of the clothing processing equipment. This helps reduce the accumulation of moisture inside the equipment, preventing liquid buildup and potential electrical safety issues.
[0062] Meanwhile, the ventilation hole 10e also facilitates ventilation and heat dissipation for the power mechanism located in the power mechanism installation area 10b. Specifically, when the power mechanism is working, it conducts heat to the surroundings, and hot air can be exhausted through the ventilation hole 10e, carrying away the heat to achieve the effect of heat dissipation.
[0063] It should be noted that the ventilation hole 10e can be set on the bottom wall of the power mechanism installation area 10b, or on the side wall of the power mechanism installation area 10b, or simultaneously on both the bottom wall and the side wall of the power mechanism installation area 10b; there are no restrictions here. There can be one ventilation hole 10e, or two or more.
[0064] It is understandable that when the moisture or heat generated by the power mechanism of the garment processing equipment is discharged through the ventilation holes, the noise generated during the operation of the power mechanism can also easily leak to the outside of the garment processing equipment through the ventilation holes, thereby increasing the noise of the garment processing equipment and affecting the user experience.
[0065] Therefore, this application embodiment is provided with at least one noise reduction structure 11 to reduce noise and absorb sound, thereby increasing the operating quality of the clothing processing equipment without affecting ventilation and heat dissipation.
[0066] The noise reduction structure 11 is located around the ventilation hole 10e, meaning that the noise reduction structure 11 is located close to the ventilation hole 10e to effectively reduce the noise flowing through the ventilation hole 10e.
[0067] In some embodiments, the ventilation hole 10e is disposed on the bottom wall of the base 10, the power mechanism is located above the ventilation hole 10e, and the noise reduction structure 11 is disposed between the power mechanism and the bottom wall of the base 10.
[0068] In other words, when the noise generated by the power mechanism flows to the ventilation hole 10e, it can first pass through the noise reduction structure 11 and be absorbed by the noise reduction structure 11. The noise reduction structure 11 reduces and silences the noise. The noise reduction structure 11 is set between the power mechanism and the bottom wall of the base 10, which can have a good sound absorption effect and at the same time make the structure of the base device 1 more compact.
[0069] Please see Figure 3 and Figure 7 The noise reduction structure 11 is provided with at least one through hole 11a, at least one connecting port 11c and at least one noise reduction cavity 11b. The through hole 11a is connected to the ventilation hole 10e to form a ventilation channel. The ventilation channel is connected to the power mechanism installation area 10b and the external environment. The connecting port 11c is connected to the through hole 11a and the noise reduction cavity 11b. The noise reduction cavity 11b is in a closed state. The connecting port 11c is connected to the noise reduction cavity 11b and the through hole 11a, so that the sound waves in the through hole 11a are transmitted to the noise reduction cavity 11b through the connecting port 11c to reduce noise.
[0070] Specifically, the ventilation hole 10e and the through hole 11a together form a ventilation channel. The water vapor generated by the clothing processing equipment and the heat generated by the power mechanism during operation can flow to the external environment through the ventilation channel, thereby reducing the accumulation of water vapor inside the clothing processing equipment and achieving ventilation and heat dissipation for the power mechanism. The connecting port 11c connects the noise reduction cavity 11b and the through hole 11a, so that the sound waves flowing through the through hole 11a can be propagated to the noise reduction cavity 11b through the connecting port 11c and absorbed in the noise reduction cavity 11b, thereby achieving sound absorption and noise reduction.
[0071] The noise reduction cavity 11b provides a noise reduction space for sound waves. The noise reduction cavity 11b is enclosed, meaning its interior is a sealed space. It is connected to the external environment only through the connecting port 11c and the through-hole 11a, allowing sound waves to propagate into the cavity and noise to be absorbed within the enclosed space. The noise reduction structure 11 can absorb high-frequency, mid-high-frequency, or mid-low-frequency noise through reflection, interference, or resonance.
[0072] It is understandable that the number of through-hole 11a, connecting port 11c, and noise reduction cavity 11b can be one or more, and there is no limitation here. Multiple noise reduction cavities 11b can not only increase the noise absorption effect, but also facilitate noise reduction processing for noise of different frequencies.
[0073] Understandably, in related technologies, sound-absorbing cotton or vibration-damping structures are used to absorb noise. However, the installation methods are complex, and the noise is passively treated by utilizing the material properties, resulting in poor sound absorption.
[0074] The base device 1 provided in this application embodiment has a noise reduction structure 11. By combining the connecting port 11c and the noise reduction cavity 11b, the noise generated by the power mechanism in the power mechanism installation area 10b during operation is actively reduced. The through hole 11a and the ventilation hole 10e of the noise reduction structure 11 together form a ventilation channel, so that the water vapor generated during the operation of the clothing processing equipment and the heat generated during the operation of the power mechanism can be discharged to the outside through the ventilation channel. This does not affect the ventilation and heat dissipation of the clothing processing equipment, and can also effectively absorb noise, thereby increasing the operating quality of the clothing processing equipment.
[0075] It is understood that in some embodiments, the through hole 11a can be coaxially arranged with the ventilation hole 10e, and the diameter of the through hole 11a is not greater than the diameter of the ventilation hole 10e. In this way, the through hole 11a does not block the ventilation hole 10e, and the noise reduction structure 11 will not reduce the airflow when it achieves noise reduction, thereby increasing the operational reliability of the base device 1.
[0076] There are no restrictions on the method of sealing the noise reduction cavity 11b.
[0077] In some embodiments, the power mechanism mounting area 10b has a mounting surface, a ventilation hole 10e penetrates the mounting surface, and a noise reduction cavity 11b is open to one side facing the mounting surface, with the mounting surface closing the open portion of the noise reduction cavity 11b.
[0078] In other words, in this embodiment, the noise reduction structure 11 and the mounting surface cooperate to close the opening of the noise reduction cavity 11b, so that the noise reduction cavity 11b is in a closed state. In this way, the overall structure of the noise reduction structure 11 can be relatively simple, reducing the manufacturing difficulty of the noise reduction structure 11.
[0079] In other embodiments, the noise reduction structure 11 separately defines a closed noise reduction cavity 11b.
[0080] In other words, the noise reduction structure 11 defines a closed noise reduction cavity 11b by itself, without the need for other structures to cooperate in sealing. This increases the sealing of the noise reduction cavity 11b, making it easier for the noise reduction cavity 11b to effectively absorb noise.
[0081] In some embodiments, please refer to Figure 1 and Figure 2 The power mechanism mounting area 10b includes at least a compressor mounting area 10c for mounting the compressor 2 and a motor mounting area 10d for mounting the motor 3. At least one of the compressor mounting area 10c and the motor mounting area 10d has a ventilation hole 10e on its bottom wall, and a noise reduction structure 11 is provided at the ventilation hole 10e.
[0082] It is understandable that the bottom wall of at least one of the compressor mounting area 10c and the motor mounting area 10d is provided with ventilation holes 10e, including various cases.
[0083] The first type: The bottom wall of the compressor installation area 10c is provided with ventilation holes 10e, and the noise reduction structure 11 is provided in the compressor installation area 10c.
[0084] The second type: The bottom wall of the motor mounting area 10d is provided with ventilation holes 10e, and the noise reduction structure 11 is provided in the motor mounting area 10d.
[0085] The third type: Ventilation holes 10e are provided on the bottom walls of both the compressor mounting area 10c and the motor mounting area 10d, and a noise reduction structure 11 is provided in both the compressor mounting area 10c and the motor mounting area 10d. In this embodiment, the water vapor generated by the clothing processing equipment can be discharged through the ventilation holes 10e provided in both the compressor mounting area 10c and the motor mounting area 10d, and the noise reduction structure 11 can respectively reduce the noise generated by the operation of the compressor 2 and the motor 3, thereby increasing the noise reduction efficiency and reliability.
[0086] In this embodiment, at least one of the compressor mounting area 10c and the motor mounting area 10d has a ventilation hole 10e on its bottom wall, so that the water vapor generated by the clothing processing equipment can have at least one discharge path, increasing the discharge efficiency. In addition, the heat generated by the compressor 2 and the motor 3 during operation can also have at least one discharge path, increasing the heat dissipation performance. At the same time, the noise reduction structure 11 can actively reduce noise to effectively improve the noise generated by the operation of the compressor 2 and the motor 3, thereby increasing the operating quality of the clothing processing equipment.
[0087] The noise reduction principle of noise reduction structure 11 is not limited.
[0088] In some embodiments, please refer to Figure 1 , Figures 3 to 5 At least one noise reduction structure 11 includes a first noise reduction structure 111, and at least one ventilation hole 10e includes a first ventilation hole.
[0089] The first noise reduction structure 111 includes a disk portion 1111 and multiple partitions 1112. The disk portion 1111 is arranged around the first ventilation hole. The through hole 11a of the first noise reduction structure 111 penetrates the disk portion 1111 along the thickness direction. The multiple partitions 1112 are arranged circumferentially along the disk portion 1111. The space between two adjacent partitions 1112 forms a noise reduction cavity 11b. The two adjacent partitions 1112 are arranged at intervals near the through hole 11a and define a communication port 11c.
[0090] It is understood that in this embodiment, multiple closed noise reduction cavities 11b can be defined by the disk portion 1111 and the partition plate 1112. That is, in this case, the first noise reduction structure 111 itself defines multiple closed noise reduction cavities 11b. Of course, multiple noise reduction cavities 11b can also be sealed by the cooperation of the disk portion 1111, the partition plate 1112, and the mounting surface with the power mechanism mounting area 10b. In this case, the first noise reduction structure 111 completes the sealing of the noise reduction cavities 11b by cooperating with the mounting surface.
[0091] The connecting port 11c and the noise reduction cavity 11b together form a quarter-wavelength tube structure.
[0092] The following is a brief explanation of the noise reduction principle of the quarter-wavelength tube structure and the first noise reduction structure 111.
[0093] The incident wave is reflected at the end of the noise reduction cavity 11b away from the connecting port 11c and superimposed on itself, thus forming a standing wave. At the end of the noise reduction cavity 11b away from the connecting port 11c, there is a 180° phase difference between the incident wave and the reflected wave, thus forming a node. At the end of the noise reduction cavity 11b closer to the connecting port 11c, the vibration of air molecules is the greatest, thus forming an antinode. Therefore, the length of the noise reduction cavity 11b is 1 / 4 of the wavelength of the sound wave corresponding to the resonant frequency. Here, the length L of the noise reduction cavity 11b is the radial extension length of the noise reduction cavity 11b along the disk portion 1111.
[0094] Specifically, f = c / 4L, where f is the frequency of the sound wave, c is the wave speed of the sound wave in the air, and L is the length of the noise reduction cavity 11b.
[0095] When a noise wave of a certain frequency enters the noise reduction cavity 11b, it is reflected within the noise reduction cavity 11b, generating a reflected sound wave with the same frequency but opposite amplitude. This reflected sound wave neutralizes the noise in the original frequency band, thereby reducing the noise in that frequency band.
[0096] In this embodiment, the cooperation of the partition 1112 and the disk 1111 of the first noise reduction structure 111 forms multiple quarter-wavelength tube structures. After the sound wave enters the noise reduction cavity 11b, it is reflected, thereby at least partially canceled out, reducing the peak frequency of the noise and achieving the purpose of noise reduction. The arrangement of multiple noise reduction cavities 11b can realize the noise reduction processing of noise sound waves of different frequencies, thereby further improving the noise reduction quality of the clothing processing equipment.
[0097] It is understood that the material used for the first noise reduction structure 111 is not limited. For example, the first noise reduction structure 111 can be made of solid materials such as plastic or metal. Of course, the first noise reduction structure 111 can also be made of materials such as silicone or rubber to further enhance the noise reduction effect.
[0098] In some embodiments, please refer to Figure 4 At least two noise reduction cavities 11b have different radial lengths L in the disk portion 1111.
[0099] It is understandable that some noise reduction cavities 11b may have different lengths in the radial direction of the disk portion 1111, while other noise reduction cavities 11b may have the same length in the radial direction of the disk portion 1111; or the lengths of each noise reduction cavity 11b in the radial direction of the disk portion 1111 may be different.
[0100] In this embodiment, the length of the noise reduction cavity 11b in the radial direction of the disk portion 1111 is different. Different lengths can reduce noise at different frequencies, thereby increasing the noise reduction range of the first noise reduction structure 111, enhancing the noise reduction effect, and further improving the operating quality of the clothing processing equipment.
[0101] In some embodiments, the length of the noise reduction cavity 11b increases sequentially in the circumferential direction of the disk portion 1111, at least within a portion of the circumference.
[0102] Here, at least within a portion of the circumference, the circle can be a circle radiating outward from the center of the disk portion 1111 or the center of the through hole 11a. Within this circumference, the length of the noise reduction cavity 11b increases. Here, the increase in the length of the noise reduction cavity 11b can be linear, exponential, or logarithmic.
[0103] In this embodiment, the length of the noise reduction cavity 11b increases sequentially along the circumference of the disk portion 1111, which facilitates adaptation to noise waves of different frequencies, thereby performing corresponding noise reduction processing and increasing the noise reduction efficiency of the first noise reduction structure 111.
[0104] There are no restrictions on the methods to achieve different lengths for each noise reduction cavity 11b.
[0105] In some embodiments, please refer to Figure 4 In the plane projection perpendicular to the height direction of the base device 1, the projections of the ends of each partition 1112 near the through hole 11a are located on the same circumference, while the projections of the ends of each partition 1112 away from the through hole 11a are located on different circumferences.
[0106] In this embodiment, the projections of the ends of each partition 1112 closest to the through hole 11a are located on the same circumference, which facilitates the uniform passage of water vapor generated by the clothing processing equipment and heat generated by the power mechanism through the ventilation channel, reducing the probability of turbulence. The projections of the ends of each partition 1112 furthest from the through hole 11a are located on different circumferences, which facilitates the formation of noise reduction cavities 11b of different lengths, thereby processing noise sound waves in different frequency ranges to increase noise reduction efficiency and effect.
[0107] The connection method between the first noise reduction structure 111 and the base 10 is not limited.
[0108] In some embodiments, please refer to Figures 3 to 5 The first noise reduction structure 111 also includes a connecting ear 1113, which is connected to the circumferential outer side of the disk portion 1111. The base device 1 includes one or more connectors that connect the connecting ear 1113 to the base 10.
[0109] In this embodiment, the connecting ear 1113 is connected to the base 10 through a connector, thereby connecting the first noise reduction structure 111 to the base 10, which facilitates increasing the installation stability of the first noise reduction structure 111.
[0110] The specific structure of the connector is not limited; it can be a screw, or a combination of a bolt and a nut.
[0111] In some embodiments, please refer to Figure 6 and Figure 7 At least one noise reduction structure 11 includes a second noise reduction structure 112, and at least one ventilation hole 10e includes a second ventilation hole.
[0112] The second noise reduction structure 112 includes a housing 1121 and at least one cylindrical portion 1122 disposed within the housing 1121. The internal space of the housing 1121 defines a noise reduction cavity 11b. The through hole 11a of the second noise reduction structure 112 penetrates the housing 1121 and the cylindrical portion 1122, and the connecting port 11c penetrates the side wall of the cylindrical portion 1122.
[0113] It is understood that in this embodiment, the closed noise reduction cavity 11b can be defined by the housing 1121 itself; that is, the second noise reduction structure 112 itself defines the closed noise reduction cavity 11b. Alternatively, the noise reduction cavity 11b can be sealed by the cooperation of the housing 1121, the cylindrical portion 1122, and the mounting surface of the power mechanism mounting area 10b. In this case, the second noise reduction structure 112 completes the sealing of the noise reduction cavity 11b by cooperating with the mounting surface.
[0114] The connecting port 11c and the noise reduction cavity 11b together constitute a Helmholtz resonance structure.
[0115] The following is a brief explanation of the noise reduction principle of the Helmholtz resonance structure and the second noise reduction structure 112.
[0116] When noise waves are incident, resonance occurs when the frequency of the incident sound waves matches the vibration frequency of the air inside the cavity, thereby absorbing sound waves within a specific frequency range to achieve noise reduction.
[0117] In this embodiment, the box 1121 and the cylindrical part 1122 of the second noise reduction structure 112 cooperate to form a Helmholtz resonance structure. After the sound wave enters the noise reduction cavity 11b, it resonates and is absorbed at least partially, thereby reducing the peak frequency of the noise and achieving the purpose of noise reduction, thus improving the noise reduction quality of the clothing processing equipment.
[0118] It is understood that the material used for the second noise reduction structure 112 is not limited. For example, the second noise reduction structure 112 can be made of solid materials such as plastic or metal. Of course, the second noise reduction structure 112 can also be made of materials such as silicone or rubber to further enhance the noise reduction effect.
[0119] Understandably, please refer to Figure 7 Multiple connecting ports 11c can be provided on a cylindrical part 1122, and sound waves enter the noise reduction cavity 11b from the multiple connecting ports 11c to increase the noise reduction efficiency of the second noise reduction structure 112.
[0120] In some embodiments, please refer to Figure 1 , Figure 6 and Figure 7 The number of second ventilation holes and the number of cylindrical parts 1122 are both multiple. The box body 1121 is provided with multiple through holes 11a. Each second ventilation hole is provided with at least one cylindrical part 1122 on the side near the power mechanism mounting area 10b.
[0121] In this embodiment, the arrangement of multiple through holes 11a, second ventilation holes, and multiple cylindrical sections 1122 can, on the one hand, facilitate the improvement of water vapor discharge efficiency and heat dissipation effect, and on the other hand, facilitate the noise reduction processing of noise of different frequencies and increase noise reduction efficiency.
[0122] In some embodiments, please refer to Figure 6 and Figure 7 The second noise reduction structure 112 includes a connecting part 1123, which is connected to the four edges of the box body 1121. The base device 1 includes at least one connecting structure, which connects the connecting part 1123 and the base 10.
[0123] In this embodiment, the connection between the connecting part 1123 and the base 10 is achieved through a connecting structure, thereby realizing the connection between the second noise reduction structure 112 and the base 10, which facilitates increasing the installation stability of the second noise reduction structure 112.
[0124] The specific structure of the connector is not limited; it can be a screw, or a combination of a bolt and a nut.
[0125] The following combination Figures 1 to 7 The base device 1 according to an embodiment of this application will be briefly described.
[0126] The base device 1 includes a base 10 and at least one noise reduction structure 11. The base 10 includes an air duct 10a and a power mechanism mounting area 10b disposed outside the air duct 10a. The power mechanism mounting area 10b includes a compressor mounting area 10c and a motor mounting area 10d. The compressor mounting area 10c and the motor mounting area 10d are respectively provided with ventilation holes 10e. The first noise reduction structure 111 is disposed above the ventilation hole 10e of the compressor mounting area 10c and between the compressor 2 and the bottom wall of the compressor mounting area 10c. The second noise reduction structure 112 is disposed above the ventilation hole 10e of the motor mounting area 10d and between the motor 3 and the bottom wall of the motor mounting area 10d.
[0127] The first noise reduction structure 111 includes a disk portion 1111 and multiple partitions 1112. The disk portion 1111 is arranged around the first ventilation hole 10e. The through hole 11a of the first noise reduction structure 111 penetrates the disk portion 1111 along the thickness direction. The multiple partitions 1112 are spaced apart circumferentially along the disk portion 1111. The space between two adjacent partitions 1112 forms a noise reduction cavity 11b, and the ends of two adjacent partitions 1112 near the through hole 11a are spaced apart and define a communication port 11c. The lengths of each noise reduction cavity 11b in the radial direction of the disk portion 1111 are all different and increase sequentially along the circumference of the disk portion 1111. The communication port 11c and the noise reduction cavities 11b together form a quarter-wavelength tube structure.
[0128] The second noise reduction structure 112 includes a housing 1121 and a plurality of cylindrical portions 1122 disposed within the housing 1121. The internal space of the housing 1121 defines a noise reduction cavity 11b. A through hole 11a of the second noise reduction structure 112 penetrates the housing 1121 and the cylindrical portions 1122, and a connecting port 11c penetrates the side wall of the cylindrical portion 1122. The connecting port 11c and the noise reduction cavity 11b together constitute a Helmholtz resonance structure.
[0129] In this embodiment, the noise generated by the compressor 2 during operation enters the noise reduction cavity 11b of the first noise reduction structure 111 and is reflected within the noise reduction cavity 11b, generating reflected sound waves with the same frequency but opposite amplitude. These reflected sound waves neutralize the noise in the original frequency band to achieve the purpose of noise reduction. The noise generated by the motor 3 during operation enters the noise reduction cavity 11b of the second noise reduction structure 112 and resonates, thereby being at least partially absorbed to achieve the purpose of noise reduction.
[0130] With the combined effect of the first noise reduction structure 111 and the second noise reduction structure 112, the noise sound pressure level in the range of 1800 to 5000 Hz is significantly improved, and the noise reduction by the first noise reduction structure 111 and the second noise reduction structure 112 is greater than 10 dB.
