Therefore, they cannot be understood as limitations on the embodiments of the present application.
[0041] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0042] An embodiment of the present application provides a base device 1 .
[0043] It should be noted that the application scenario of the base device 1 is not limited. In the embodiment of the present application, the base device 1 is described as being used in a clothing processing device.
[0044] An embodiment of the present application provides a clothing processing device, including a drum assembly, a power mechanism, and a base device 1 of any embodiment of the present application.
[0045] It is understood that the specific form of the clothes processing device is not limited. For example, the clothes processing device can at least be used to dry clothes. The clothes processing device can be a clothes dryer, a washer-dryer, etc.
[0046] The drum assembly has a clothes treating chamber.
[0047] The specific structure of the barrel assembly is not limited. For example, the barrel assembly may include an inner barrel and an outer barrel, the outer barrel is mounted on the outside of the inner barrel, the outer barrel is used to hold water required for washing clothes, and the inner barrel is used to hold clothes, and the space inside the inner barrel defines a clothes processing chamber. For example, the inner barrel and the outer barrel are coaxially arranged inside and outside, and holes are provided on the side wall of the inner barrel. The water in the outer barrel can enter the inner barrel through the holes in the inner barrel to wash the clothes in the clothes processing chamber. In this embodiment, the inner barrel can also be referred to as a perforated inner barrel. In other embodiments, the inner barrel can be referred to as a non-perforated inner barrel. Of course, in some other embodiments, the barrel assembly may also include only the inner barrel, and the inner barrel relies on itself to hold water and clothes.
[0048] See also Figures 1 to 2 The base device 1 includes a base 10 and at least one noise reduction structure 11.
[0049] The base 10 may be disposed below the drum assembly, that is, the base 10 may be disposed in the bottom space of the clothes processing device.
[0050] The base 10 includes an air duct 10a and a power mechanism installation area 10b disposed outside the air duct 10a. The power mechanism is disposed in the power mechanism installation area 10b.
[0051] The air duct 10a is in communication with the laundry processing chamber. Specifically, the air duct 10a is used for air circulation, and the air flow can circulate between the air duct 10a and the laundry processing chamber to dry the laundry.
[0052] The power mechanism installation area 10b is arranged outside the air duct 10a, that is, the power mechanism is arranged outside the air duct 10a, which can facilitate the circulation of air around the power mechanism when it is running, enhance the heat dissipation effect, and reduce the impact of the heat generated by the power mechanism when it is running on the heat exchange components in the air duct 10a. At the same time, it is also convenient for disassembly, assembly and maintenance of the power mechanism without affecting the structure in the air duct 10a.
[0053] In some embodiments, the power mechanism includes a motor 3 and / or a compressor 2 .
[0054] The compressor 2 is used to compress the refrigerant. The compressor 2 has an air intake port and an air exhaust port. The compressor 2 inhales the refrigerant with a lower temperature and lower pressure from the air intake port, drives the piston to compress the refrigerant through the operation of the motor 3, and outputs the refrigerant with increased temperature and pressure from the exhaust port.
[0055] It can be understood that refrigerant, also known as coolant or snow seed, is the medium substance used to complete the heat exchange cycle.
[0056] Exemplarily, the laundry processing apparatus includes a heat exchange assembly, which includes an evaporator and a condenser. The evaporator and condenser are disposed within air duct 10a, with the evaporator positioned upstream of the condenser in the direction of airflow. The evaporator condenses and dehumidifies the airflow, while the condenser heats the airflow. 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 description of the drying process and principle of the clothes processing equipment.
[0058] When drying clothes, the dry hot air flow in the air duct 10a enters the clothing processing chamber from the air duct 10a, exchanges heat and moisture with the clothes in the clothing processing chamber, and then turns into a moist hot air flow. The moist hot air flow flows through the evaporator, where the refrigerant absorbs heat and reduces the temperature, turning it into a low-temperature dry air flow. The low-temperature dry air flow absorbs heat from the refrigerant at the condenser and increases its temperature, turning it into a dry hot air flow, which exchanges heat with the clothes again. In this way, the cycle operates to achieve continuous and efficient drying of clothes.
[0059] It should be noted that the low-temperature dry airflow is relative to the moist hot airflow, and the temperature of the low-temperature dry airflow is lower than that of the moist hot airflow. The low temperature in the embodiment of the present application may be room temperature.
[0060] See also Figure 1 The power mechanism installation 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 when a clothes drying device is operating, it generates a significant amount of water vapor. In this embodiment, ventilation holes 10e are provided to communicate with the external environment, allowing water vapor to be discharged to the exterior of the clothes drying device through the ventilation holes 10e. This helps reduce the accumulation of water vapor within the clothes drying device, which could lead to liquid accumulation and electrical safety issues.
[0062] At the same time, the provision of the ventilation holes 10e can also facilitate ventilation and heat dissipation of the power mechanism disposed in the power mechanism installation area 10b. Specifically, when the power mechanism is working, heat is transferred to the surroundings, and hot air can be discharged through the ventilation holes 10e, taking away the heat to achieve a heat dissipation effect.
[0063] It should be noted that the ventilation hole 10e can be provided on the bottom wall of the power mechanism installation area 10b, or on the side wall of the power mechanism installation area 10b, or can be provided on both the bottom wall and the side wall of the power mechanism installation area 10b, without limitation. The number of ventilation holes 10e can be one, or two or more.
[0064] It is understandable that when the water vapor of the clothing processing device or the heat generated during the operation of the power mechanism is discharged through the ventilation holes, the noise generated during the operation of the power mechanism is also easy to leak to the outside of the clothing processing device through the ventilation holes, thereby increasing the noise of the clothing processing device and affecting the user experience.
[0065] Therefore, the embodiment of the present application is provided with at least one noise reduction structure 11 to reduce noise and absorb sound, thereby improving the operating quality of the clothing processing equipment without affecting ventilation and heat dissipation.
[0066] The noise reduction structure 11 is disposed around the ventilation hole 10e, which means that the noise reduction structure 11 is disposed close to the ventilation hole 10e to better weaken the noise flowing through the ventilation hole 10e.
[0067] In some embodiments, the ventilation hole 10 e is provided on the bottom wall of the base 10 , the power mechanism is located above the ventilation hole 10 e , and the noise reduction structure 11 is provided between the power mechanism and the bottom wall of the base 10 .
[0068] That is to say, when the noise generated by the power mechanism flows toward 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 arranged between the power mechanism and the bottom wall of the base 10, and can have a good sound absorption effect. At the same time, it can also make the structure of the base device 1 more compact.
[0069] See also Figure 3 and Figure 7 The noise reduction structure 11 is provided with at least one through hole 11a, at least one communicating port 11c and at least one noise reduction cavity 11b. The through hole 11a is communicated with the ventilation hole 10e to form a ventilation channel, which connects the power mechanism installation area 10b and the external environment. The communicating port 11c connects the through hole 11a and the noise reduction cavity 11b. The noise reduction cavity 11b is in a closed state. The communicating port 11c connects 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 communicating port 11c to reduce noise.
[0070] Specifically, vent 10e and through hole 11a together form a ventilation channel, through which moisture generated by the clothing processing device and heat generated by the power mechanism can flow to the external environment, reducing the accumulation of moisture inside the clothing processing device and achieving ventilation and heat dissipation of the power mechanism. Communication port 11c connects noise reduction chamber 11b and through hole 11a, so that sound waves flowing through through hole 11a can propagate through communication port 11c into noise reduction chamber 11b, where they are absorbed, thereby achieving sound absorption and noise reduction.
[0071] Noise reduction cavity 11b is used to provide a noise reduction space for sound waves. Noise reduction cavity 11b is closed, meaning that the interior of noise reduction cavity 11b is a closed space. Noise reduction cavity 11b is connected to through-hole 11a and, in turn, the external environment only through communication port 11c. This facilitates the propagation of sound waves into noise reduction cavity 11b, allowing noise to be absorbed within the closed space. Noise reduction structure 11 can absorb high-frequency, mid-high-frequency, or mid-low-frequency noise through reflection, interference, or resonance.
[0072] It is understood that the number of the through hole 11a, the communication port 11c and the 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 of noises of different frequencies.
[0073] It is understandable that in the related art, sound-absorbing cotton or vibration isolation structure is used to absorb noise, the installation method is complicated, and the noise is passively processed by using the material properties, and the sound absorption effect is poor.
[0074] The base device 1 provided in the embodiment of the present application, the setting of the noise reduction structure 11, utilizes the combination of the connecting port 11c and the noise reduction cavity 11b to actively reduce the noise generated during the operation of the power mechanism arranged in the power mechanism installation area 10b, and the through hole 11a of the noise reduction structure 11 and the ventilation hole 10e together constitute a ventilation channel, so as to facilitate the discharge of water vapor generated during the operation of the clothing processing equipment and the heat generated during the operation of the power mechanism to the outside through the ventilation channel, which does not affect the ventilation and heat dissipation of the clothing processing equipment, and can also effectively absorb the noise, thereby improving the operation quality of the clothing processing equipment.
[0075] It can be understood that in some embodiments, the through hole 11a can be coaxially arranged with the ventilation hole 10e, and the aperture of the through hole 11a is not larger than the aperture of the ventilation hole 10e. In this way, the setting of the through hole 11a does not block the ventilation hole 10e, and the noise reduction structure 11 will not reduce the airflow flow when achieving noise reduction, thereby increasing the operating reliability of the base device 1.
[0076] There is no limitation on the method for sealing the noise reduction cavity 11b.
[0077] In some embodiments, the power mechanism installation area 10b has a mounting surface, the ventilation hole 10e passes through the mounting surface, the noise reduction cavity 11b is open toward one side of the mounting surface, and the mounting surface closes the opening of the noise reduction cavity 11b.
[0078] That is to say, in this embodiment, the noise reduction structure 11 cooperates with the mounting surface to close the open portion 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 alone defines a closed noise reduction cavity 11 b.
[0080] That is to say, the closed noise reduction cavity 11b is defined by the noise reduction structure 11 itself, and there is no need to cooperate with other structures for sealing. In this way, the sealing performance of the noise reduction cavity 11b can be increased, and the noise reduction cavity 11b can effectively absorb noise.
[0081] For some examples, see Figure 1 and Figure 2 The power mechanism installation area 10b includes at least a compressor installation area 10c for installing the compressor 2 and a motor installation area 10d for installing the motor 3. The bottom wall of at least one of the compressor installation area 10c and the motor installation area 10d is provided with a ventilation hole 10e, and a noise reduction structure 11 is provided at the ventilation hole 10e.
[0082] It can be understood that there are various cases in which the bottom wall of at least one of the compressor installation area 10c and the motor installation area 10d is provided with the ventilation hole 10e.
[0083] The first type: a ventilation hole 10e is provided on the bottom wall of the compressor installation area 10c, and a noise reduction structure 11 is provided in the compressor installation area 10c.
[0084] The second type: the bottom wall of the motor installation area 10d is provided with ventilation holes 10e, and the noise reduction structure 11 is provided in the motor installation area 10d.
[0085] The third embodiment comprises ventilation holes 10e provided on the bottom wall of both the compressor mounting area 10c and the motor mounting area 10d, with noise reduction structures 11 disposed in both areas. In this embodiment, moisture generated by the laundry processing device can be discharged through the ventilation holes 10e provided in both the compressor mounting area 10c and the motor mounting area 10d. Furthermore, the noise reduction structures 11 can reduce the noise generated by the operation of the compressor 2 and the motor 3, respectively, thereby increasing noise reduction efficiency and reliability.
[0086] In this embodiment, the bottom wall of at least one of the compressor installation area 10c and the motor installation area 10d is provided with a ventilation hole 10e, that is, the water vapor generated by the clothing processing equipment can have at least one discharge path, thereby increasing the discharge efficiency, and the heat generated when the compressor 2 and the motor 3 are running can also have at least one discharge path, thereby 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 operation quality of the clothing processing equipment.
[0087] The noise reduction principle of the noise reduction structure 11 is not limited.
[0088] For some examples, see 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] Among them, 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 passes through the disk portion 1111 along the thickness direction. The multiple partitions 1112 are arranged at intervals along the circumference of the disk portion 1111. The space between two adjacent partitions 1112 forms a noise reduction cavity 11b, and the two adjacent partitions 1112 are arranged at intervals near one end of the through hole 11a and define a connecting port 11c.
[0090] It will be appreciated that in this embodiment, the disk portion 1111 and the partition 1112 define multiple enclosed noise reduction cavities 11b. In this case, the first noise reduction structure 111 itself defines multiple enclosed noise reduction cavities 11b. Of course, the multiple noise reduction cavities 11b can also be enclosed by the disk portion 1111, the partition 1112, and the mounting surface of 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 communication port 11 c and the noise reduction cavity 11 b together form a quarter-wavelength tube structure.
[0092] The noise reduction principle of the quarter-wavelength tube structure and the first noise reduction structure 111 is briefly described below.
[0093] The incident wave is reflected at the end of the noise reduction cavity 11b away from the communication port 11c and superimposed with itself, forming a standing wave. At this end, there's a 180° phase difference between the incident and reflected waves, resulting in nodes. At the end of the noise reduction cavity 11b closer to the communication port 11c, the vibration of air molecules is greatest, forming antinodes. Therefore, the length of the noise reduction cavity 11b is 1 / 4 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 of the 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 velocity 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 in the noise reduction cavity 11b, generating a reflected sound wave with the same frequency and opposite amplitude. The reflected sound wave neutralizes the noise of the original frequency band to reduce the noise in this frequency band.
[0096] In this embodiment, the partition 1112 and the disk 1111 of the first noise reduction structure 111 cooperate to form multiple quarter-wavelength tube structures. After the sound waves enter the noise reduction cavity 11b, they are reflected and thus at least partially offset, thereby reducing the peak frequency of the noise and achieving the purpose of silencing and noise reduction. The setting of multiple noise reduction cavities 11b can realize noise reduction processing of noise 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 and metal. Of course, the first noise reduction structure 111 can also be made of materials such as silicone and rubber to further enhance the noise reduction effect.
[0098] For some examples, see Figure 4 , at least two noise reduction cavities 11 b have different lengths L in the radial direction of the disk portion 1111 .
[0099] It is understandable that the lengths of some noise reduction cavities 11b in the radial direction of the disk portion 1111 may be different, while the lengths of other noise reduction cavities 11b in the radial direction of the disk portion 1111 may be the same; or the lengths of all noise reduction cavities 11b in the radial direction of the disk portion 1111 may be different.
[0100] In this embodiment, the noise reduction cavity 11b has different lengths in the radial direction of the disk portion 1111. Different lengths can reduce and silence noises of 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, in the circumferential direction of the disk portion 1111 , the length of the noise reduction cavity 11 b in at least a portion of the circumference increases sequentially.
[0102] Here, at least a portion of the circumference may 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 may 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 , so as to adapt 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 is no limitation on the manner of achieving different lengths of the noise reduction cavities 11 b.
[0105] For some examples, see Figure 4 In the plane projection perpendicular to the height direction of the base device 1, the projections of one end of each partition 1112 close to the through hole 11a are located on the same circumference, and the projections of one end of each partition 1112 away from the through hole 11a are located on different circumferences.
[0106] In this embodiment, the projections of one end of each partition 1112 close to the through hole 11a are located on the same circumference, which can facilitate the uniform passage of water vapor generated by the clothing processing equipment and the heat generated by the power mechanism through the ventilation channel, reducing the probability of turbulence. The projections of one end of each partition 1112 away from the through hole 11a are located on different circumferences, which can facilitate the formation of noise reduction cavities 11b of different lengths, thereby processing noise waves within different frequency ranges to increase the noise reduction efficiency and noise reduction effect.
[0107] The connection method between the first noise reduction structure 111 and the base 10 is not limited.
[0108] For some examples, see Figures 3 to 5 The first noise reduction structure 111 further 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 connecting members, which connect the connecting ear 1113 and the base 10 .
[0109] In this embodiment, the connection between the connecting ear 1113 and the base 10 is achieved through a connecting piece, thereby achieving the connection between the first noise reduction structure 111 and the base 10, which facilitates increasing the installation stability of the first noise reduction structure 111.
[0110] The specific structure of the connecting piece is not limited, and can be a screw, or a combination of a bolt and a nut.
[0111] For some examples, see 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] Among them, the second noise reduction structure 112 includes a box body 1121 and at least one cylindrical portion 1122 arranged in the box body 1121. The internal space of the box body 1121 defines a noise reduction cavity 11b. The through hole 11a of the second noise reduction structure 112 passes through the box body 1121 and the cylindrical portion 1122, and the communicating port 11c passes through the side wall of the cylindrical portion 1122.
[0113] It is understood that in this embodiment, the box body 1121 itself can define a closed noise reduction chamber 11b, that is, in this case, the second noise reduction structure 112 itself defines the closed noise reduction chamber 11b. Of course, the noise reduction chamber 11b can also be sealed by the box body 1121, the barrel 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 chamber 11b by cooperating with the mounting surface.
[0114] The communication port 11 c and the noise reduction cavity 11 b together form a Helmholtz resonance structure.
[0115] The following briefly describes the noise reduction principle of the Helmholtz resonance structure and the second noise reduction structure 112 .
[0116] When noise sound waves are incident, when the frequency of the incident sound waves matches the air vibration frequency in the cavity, resonance occurs, thereby absorbing sound waves within a specific frequency range to achieve the purpose of noise reduction.
[0117] In this embodiment, the box body 1121 and the tube 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 at least partially absorbed, thereby reducing the peak frequency of the noise and achieving the purpose of silencing and noise reduction, thereby improving the noise reduction quality of the clothing processing equipment.
[0118] It is understood that the material of 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 and metal. Of course, the second noise reduction structure 112 can also be made of materials such as silicone and rubber to further enhance the noise reduction effect.
[0119] Understandably, see Figure 7 A plurality of communication ports 11 c may be provided on one cylindrical portion 1122 , and sound waves enter the noise reduction cavity 11 b through the plurality of communication ports 11 c to increase the noise reduction efficiency of the second noise reduction structure 112 .
[0120] For some examples, see Figure 1 、 Figure 6 and Figure 7 The number of the second ventilation holes and the number of the barrels 1122 are respectively multiple, the box body 1121 is provided with multiple through holes 11a, and at least one barrel 1122 is provided on one side of each second ventilation hole close to the power mechanism installation area 10b.
[0121] In this embodiment, the provision of multiple through holes 11a, second ventilation holes and multiple cylindrical portions 1122, on the one hand, can facilitate the improvement of water vapor discharge efficiency and heat dissipation effect, and on the other hand, can also facilitate the noise reduction processing of noises of different frequencies and increase the noise reduction efficiency.
[0122] For some examples, see Figure 6 and Figure 7 The second noise reduction structure 112 includes a connecting portion 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 portion 1123 and the base 10 .
[0123] In this embodiment, the connection between the connecting portion 1123 and the base 10 is achieved through the connection structure, thereby achieving the connection between the second noise reduction structure 112 and the base 10, thereby increasing the installation stability of the second noise reduction structure 112.
[0124] The specific structure of the connecting piece is not limited, and can be a screw, or a combination of a bolt and a nut.
[0125] The following combination Figures 1 to 7 , a brief description is given of the base device 1 according to an embodiment of the present application.
[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 installation area 10b arranged outside the air duct 10a. The power mechanism installation area 10b includes a compressor installation area 10c and a motor installation area 10d. The compressor installation area 10c and the motor installation area 10d are respectively provided with ventilation holes 10e. The first noise reduction structure 111 is arranged above the ventilation holes 10e of the compressor installation area 10c, and is arranged between the compressor 2 and the bottom wall of the compressor installation area 10c. The second noise reduction structure 112 is arranged above the ventilation holes 10e of the motor installation area 10d, and is arranged between the motor 3 and the bottom wall of the motor installation area 10d.
[0127] The first noise reduction structure 111 comprises a disk portion 1111 and a plurality of baffles 1112. The disk portion 1111 is arranged around the first ventilation hole 10e. A through hole 11a of the first noise reduction structure 111 extends through the disk portion 1111 along its thickness. The baffles 1112 are spaced apart along the circumference of the disk portion 1111. The space between two adjacent baffles 1112 forms a noise reduction cavity 11b. Two adjacent baffles 1112 are spaced apart near one end of the through hole 11a and define a communication port 11c. The lengths of the noise reduction cavities 11b in the radial direction of the disk portion 1111 vary and increase in length 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 box body 1121 and multiple cylindrical portions 1122 disposed within the box body 1121. The interior space of the box body 1121 defines a noise reduction cavity 11b. The through hole 11a of the second noise reduction structure 112 extends through the box body 1121 and the cylindrical portions 1122, and the communication port 11c extends through the side wall of the cylindrical portion 1122. The communication port 11c and the noise reduction cavity 11b together form a Helmholtz resonance structure.
[0129] In this embodiment, the noise generated when the compressor 2 is running enters the noise reduction cavity 11b of the first noise reduction structure 111, and is reflected in the noise reduction cavity 11b to generate a reflected sound wave with the same frequency and opposite amplitude. The reflected sound wave and the noise in the original frequency band neutralize each other to achieve the purpose of sound insulation and noise reduction; the noise generated when the motor 3 is running enters the noise reduction cavity 11b of the second noise reduction structure 112, resonates, and is at least partially absorbed to achieve the purpose of sound insulation and noise reduction.
[0130] With the cooperation of the first noise reduction structure 111 and the second noise reduction structure 112, the noise sound pressure level in the range of 1800-5000 Hz is significantly improved, and the first noise reduction structure 111 and the second noise reduction structure 112 reduce the noise by more than 10 dB.
