[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Please refer to the following Figure 1-Figure 12 A cabinet 100 according to an embodiment of the present invention is described.

[0046] Reference Figure 1 , Figure 4 and Fig. 9 The housing 100 according to the first embodiment of the present invention is applied to a compressor assembly, and the housing 100 includes: a plurality of enclosures 10, an extension pipe 20 and a first pipe 30.

[0047] Specifically, a plurality of enclosures 10 enclose a compressor installation cavity, at least one enclosure 10 has a resonance cavity 11 and a connecting hole 12, that is, one, two, or three or more enclosures 10 may have a resonance cavity 11 and a connecting hole 12, the resonance cavity 11 is connected to the compressor installation cavity through the connecting hole 12, the resonance cavity 11 has a first inner wall 111 and a second inner wall 112 arranged oppositely, and the connecting hole 12 passes through the first inner wall 111; the extension tube 20 is connected to the periphery of the connecting hole 12, and at least a portion of the extension tube 20 extends into the resonance cavity 11, that is, the extension tube 20 may partially extend into the resonance cavity 11, or the extension tube 20 may fully extend into the resonance cavity 11; one end of the first tube 30 (such as Fig. 9 The rear end of the first tube 30 shown in FIG. 1 is fixed to the second inner wall 112 and the other end (as shown in FIG. Fig. 9 The front end of the first tube 30 shown in the figure is spaced apart from the first inner wall 111, and the first tube 30 is sleeved on the radially outer side of the extension tube 20 and spaced apart from the outer wall of the extension tube 20. That is to say, the extension tube 20 is arranged on the radially inner side of the first tube 30, and the inner wall of the first tube 30 and the outer wall of the extension tube 20 define a first channel 51 for sound propagation, thereby further increasing the propagation distance of the sound in the resonance cavity 11.

[0048] For example, Figure 4 and Fig. 9 As shown, the wall on the front side of the resonance cavity 11 is the first inner wall 111, and the wall on the rear side of the resonance cavity 11 is the second inner wall 112. The connecting hole 12 penetrates the first inner wall 111 along the front-to-back direction. The extension tube 20 is connected to the periphery of the connecting hole 12. The front end of the extension tube 20 extends out of the resonance cavity 11, and the rear end of the extension tube 20 extends into the resonance cavity 11. A first tube 30 is provided on the radial outer side of the extension tube 20 in the resonance cavity 11. The inner wall of the first tube 30 is spaced apart from the outer wall of the extension tube 20. The rear end of the first tube 30 is connected to the second inner wall 112. The front end of the first tube 30 extends forward and is not connected to the first inner wall 111. In this way, the inner wall of the first tube 30 and the outer wall of the extension tube 20 define a first channel 51, and the first channel 51 is connected to the extension tube 20.

[0049] When the compressor is running in the housing 100, the noise generated by the compressor will continue to propagate along the extension tube 20 after passing through the connecting hole 12 from the extension tube 20, and then the noise will enter the first channel 51 from the inside of the extension tube 20 and continue to propagate. This can increase the propagation distance of the noise in the resonance cavity 11, reduce the frequency band of the noise, and make the frequency band of the noise adapt to the noise reduction frequency band of the resonance cavity 11. Then, the noise enters the depth of the resonance cavity 11 from the first channel 51. When the sound wave frequency is the same as the natural frequency of the resonance cavity 11, resonance will occur in the resonance cavity 11, and the movement speed of air with a certain mass in the resonance cavity 11 will be accelerated, the friction resistance of the air will increase, and a large amount of sound energy will be converted into heat energy and consumed, thereby achieving the purpose of silencing. In this way, the noise transmission of the compressor components to the outside can be reduced, and the decibel of the compressor noise heard by the outside world is reduced.

[0050] Therefore, the resonance cavity 11 can absorb noise, reduce the decibel of noise, improve the noise reduction ability of the box 100, and enable the compressor assembly to run relatively quietly, thereby improving the user experience of the air conditioner. In addition, the first tube 30 is provided to enable the resonance cavity 11 to achieve lower frequency noise absorption within the limited resonance cavity 11. At the same time, under the premise of reducing the volume of the resonance cavity 11, the same absorption coefficient can be maintained as that of the solution in which the volume of the resonance cavity 11 is not reduced, thereby reducing the volume of the resonance cavity 11 and facilitating the production and application of the box 100.

[0051] According to the cabinet 100 of the embodiment of the present invention, a resonance cavity 11 is arranged in the enclosure 10. The resonance cavity 11 can absorb noise, reduce the decibel of noise, and improve the noise reduction ability of the cabinet 100, thereby improving the use experience of the air conditioner. At the same time, an extension pipe 20 is arranged at the position of the connecting hole 12. The extension pipe 20 can guide the noise from the installation cavity into the resonance cavity 11. At the same time, the extension pipe 20 can also increase the propagation distance of the noise in the resonance cavity 11, thereby reducing the frequency band of the noise and making the frequency band of the noise adapt to the noise reduction frequency band of the resonance cavity 11, thereby ensuring the noise reduction effect.

[0052] Furthermore, by providing a first tube 30 fixed to the second inner wall 112 and sleeved on the outside of the extension tube 20, the first tube 30 and the extension tube 20 cooperate to form a first channel 51, which can further increase the propagation distance of the noise in the resonance cavity 11, thereby further reducing the frequency band of the noise, making the frequency band of the noise adapt to the noise reduction frequency band of the resonance cavity 11, so that noise in a wider frequency band can be reduced in the resonance cavity 11, further improving the noise reduction effect of the box 100, and at the same time, in a limited resonance cavity 11, the resonance cavity 11 can achieve lower frequency noise absorption, and can also reduce the volume of the resonance cavity 11, which is convenient for the production and application of the box 100.

[0053] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , the resonance frequency of the box 100 is 100Hz-1000Hz. Therefore, the box 100 can absorb the noise of the compressor at a frequency of 100Hz-8000Hz.

[0054] For example, the resonance frequency of the housing 100 may be 100 Hz, 500 Hz, 1000 Hz, 1500 Hz, 2000 Hz, 2500 Hz, 3000 Hz, 3500 Hz or 4000 Hz.

[0055] According to some embodiments of the present invention, referring to Figure 1 and Fig.12 The housing 100 may further include a second tube 40, one end of which (eg Fig.12 The front end of the second tube 40 shown in FIG. 1 is fixed to the first inner wall 111 and the other end (as shown in FIG. Fig.12 The rear end of the second tube 40 shown in the figure is spaced apart from the second inner wall 112, and the second tube 40 is sleeved on the radially outer side of the first tube 30 and spaced apart from the outer wall of the first tube 30. Thus, the second tube 40 and the first tube 30 define a second channel 52 for noise propagation, further increasing the propagation distance of the noise in the resonance cavity 11, further reducing the frequency band of the noise in the resonance cavity 11, thereby making the frequency band of the noise more matched with the noise reduction frequency band of the resonance cavity 11, and further improving the noise reduction effect of the box 100.

[0056] For example, Fig.12 As shown, the front end of the second tube 40 is fixed to the first inner wall 111, the rear end of the second tube 40 extends backward and is spaced apart from the second inner wall 112, the inner wall of the second tube 40 and the outer wall of the first tube 30 define a second channel 52, and the second channel 52 is connected to the first channel 51. The noise propagates from front to back in the extension tube 20, then enters the first channel 51, and propagates from back to front in the first channel 51, then enters the second channel 52 from the first channel 51, and propagates from front to back in the second channel 52.

[0057] According to some optional embodiments of the present invention, referring to Figure 1 and Fig.12 , the first tube 30 is one or more, that is, the first tube 30 can be one, two or three or more, the second tube 40 is one or more, that is, the second tube 40 can be one, two or three or more, and the first tube 30 and the second tube 40 are alternately arranged from inside to outside in the radial direction. Therefore, the plurality of first tubes 30 and the plurality of second tubes 40 define the third channel 53 for noise propagation, which can further increase the distance of noise propagation in the resonance cavity 11, and can further reduce the frequency band of noise, so as to ensure the noise reduction effect of the box 100 and the noise reduction ability of the box 100.

[0058] For example, Fig.12 As shown, a second tube 40 is arranged at the radial outer end of the first tube 30, and another first tube 30 is arranged at the radial outer end of the second tube 40. The second tube 40 and the first tube 30 at the radial outer end of the second tube 40 define a third channel 53, and the third channel 53 is connected with the second channel 52. When the noise propagates in the resonance cavity 11, the noise first enters the resonance cavity 11 from the extension tube 20 through the connecting hole 12. In the resonance cavity 11, the noise first propagates from the back to the front in the first channel 51, and then the noise enters the second channel 52. The noise propagates from the front to the back in the second channel 52. After that, the noise enters the third channel 53. The noise propagates from the back to the front in the third channel 53. Finally, the noise enters the deepest part of the resonance cavity 11 from the front end of the third channel 53. At this time, the noise propagates in the resonance cavity 11.

[0059] The number of the first tubes 30 and the second tubes 40 to be arranged is determined according to the noise reduction frequency of the resonance cavity 11 and the frequency of the noise itself. When the noise frequency is high and the noise reduction frequency of the resonance cavity 11 is low, more first tubes 30 and second tubes 40 need to be arranged, for example, three first tubes 30 and three second tubes 40 are arranged, so that the propagation distance of the noise in the resonance cavity 11 will be increased, so that the high-frequency noise can be reduced to a lower frequency band, which is convenient for matching with the noise reduction frequency band of the resonance cavity 11. When the noise frequency is low and the difference between the noise reduction frequency of the resonance cavity 11 and the noise frequency is small, fewer first tubes 30 and second tubes 40 can be arranged, for example, one first tube 30 and one second tube 40 are arranged, so that the propagation distance of the noise in the resonance cavity 11 is slightly increased, and the frequency of the noise can be matched with the noise reduction frequency band of the resonance cavity 11.

[0060] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 The box body 100 has a plurality of resonance chambers 11. In this way, the noise reduction effect of the box body 100 can be improved, and the user experience of the air conditioner can be enhanced.

[0061] It should be noted that a single resonant cavity 11, a connecting hole 12 and an extension tube 20 form a single Helmholtz resonator, and the resonant frequency of the single Helmholtz resonator is M a C is the acoustic mass of the Helmholtz resonator, which is related to the outward extension length of the extension tube 20, the length of the extension tube 20 in the resonance cavity 11, and the diameter of the extension tube 20. The longer the extension tube 20 is, the greater the acoustic mass is, and the resonance frequency shifts toward the low frequency direction. a It is the acoustic compliance of the Helmholtz resonator, which is related to the cavity volume of the resonance cavity 11 of the Helmholtz resonator. By changing the size of the extension tube 20, the cavity volume can be adjusted in a wider frequency range, thereby increasing the degree of freedom of adjustment of the box 100.

[0062] The resonance frequencies of the multiple resonance cavities 11 in the above embodiment can be the same, so that the multiple resonance cavities 11 can absorb noise in the same frequency range, so that the location where the compressor generates noise in a specific frequency band can be centrally set to minimize the noise in this frequency band; the resonance frequencies of the multiple resonance cavities 11 can be different, so that the multiple resonance cavities 11 can absorb noise in different frequency ranges, thereby expanding the frequency band range for the box 100 to absorb noise, and being able to effectively reduce the noise in multiple frequency bands generated by the compressor.

[0063] Furthermore, if Figure 1 and Figure 4As shown, the enclosure 10 has a plurality of resonance chambers 11. In this way, when the compressor generates noise during operation, the noise generated at any position of the compressor can enter the resonance chamber 11 through the connecting hole 12, thereby improving the noise reduction capability of the box 100.

[0064] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 4 , the lengths of any two extension tubes 20 extending into the resonance cavity 11 are the same or different. The length of the extension tube 20 extending into the resonance cavity 11 can control the propagation distance of the noise in the resonance cavity 11, thereby adjusting the degree of noise frequency reduction. Therefore, the length of the extension tube 20 can be reasonably designed according to the frequency of the noise and the noise reduction frequency of the resonance cavity 11.

[0065] According to some optional embodiments of the present invention, referring to Figure 1 and Figure 4 , the lengths of the first tubes 30 in any two resonance cavities 11 are the same or different. The length of the first tube 30 can control the propagation distance of the noise in the resonance cavity 11, thereby further adjusting the degree of noise frequency reduction. Therefore, when the length of the extension tube 20 does not reduce the frequency band of the noise to the noise reduction frequency band of the resonance cavity 11, the frequency band of the noise can be reduced to the noise reduction frequency band of the resonance cavity 11 by adjusting the length of the first tube 30, thereby increasing the design freedom of the extension tube 20 and the first tube 30 and making the structural arrangement more reasonable.

[0066] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 At least two resonance cavities 11 have different volumes, that is, two, three, four or more resonance cavities 11 may have different volumes. Resonance cavities 11 with different volumes may have different noise reduction frequencies, thereby expanding the range of the noise reduction frequency of the box 100.

[0067] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 , in the thickness direction of the enclosure 10 (such as Figure 1 In the front-to-back direction (shown in the figure), at least two resonance cavities 11 have different depths, that is, two, three, four or more resonance cavities 11 may have different depths. In this way, the depth of the resonance cavity 11 can be arranged according to the installation space in the installation cavity, so that the structural arrangement in the installation cavity can be more reasonable.

[0068] According to some embodiments of the present invention, referring to Figure 1 and Figure 4, the resonance frequency interval of the housing 100 includes multiple interval units, that is, the resonance frequency interval of the housing 100 may include two, three, or four or more interval units, the housing 100 has multiple resonance cavities 11, that is, the housing 100 may have two, three, or four or more resonance cavities 11, and any interval unit is correspondingly provided with at least one resonance cavity 11, that is, any interval unit may be correspondingly provided with one, two, or three or more resonance cavities 11. In this way, the frequency bands of the multiple interval units absorbing noise constitute the interval range of the resonance frequency. When the compressor is running, the noise of the compressor can be reduced in the resonance cavities 11 of different resonance frequencies, thereby improving the noise reduction effect of the housing 100.

[0069] For example, Figure 4 As shown, the box 100 includes a plurality of enclosures 10, and a single enclosure 10 has a resonance frequency interval with twenty-five interval units, each interval unit corresponds to a resonance cavity 11, and the volumes of two adjacent resonance cavities 11 are different, the lengths of the first tube 30 and the second tube 40 in the two adjacent resonance cavities 11 are different, and the diameters of two adjacent extension tubes 20 are different, so that the box 100 can effectively reduce the noise of a certain frequency range. When the compressor is running, the position of the motor and rotor of the compressor and the position of the liquid reservoir generate low-frequency noise, and the resonance cavity 11 of the low-frequency interval unit is set at this position; the exhaust position generates high-frequency noise, and the resonance cavity 11 of the high-frequency interval unit needs to be set at this position.

[0070] According to some embodiments of the present invention, referring to Figure 1 , Figure 4 and Figure 5 The plurality of enclosures 10 enclose a compressor installation cavity with an open bottom. In this way, after the compressor is installed, the box body 100 composed of the plurality of enclosures 10 is directly placed on the upper side of the compressor, thereby facilitating the installation of the box body 100.

[0071] For example, a total of five enclosures 10 are provided, and the five enclosures 10 enclose a box 100 with an open lower portion, and the box 100 cover is arranged on the upper side of the mounting plate, and the box 100 cooperates with the mounting plate to form a closed mounting cavity. When assembling the air conditioner, the compressor and the liquid accumulator are first installed on the mounting plate, and then the box 100 composed of multiple enclosures 10 is covered on the upper side of the compressor, and the box 100 and the mounting plate form a closed whole, so that the compressor and the liquid accumulator can be protected in the mounting cavity.

[0072] According to some embodiments of the present invention, referring to Figure 4 , Fig. 9 and Fig.10The enclosure 10 includes: an outer plate portion 101, an inner plate portion 102 and a partition portion 103. The outer plate portion 101 and the inner plate portion 102 are arranged at intervals along the thickness direction of the enclosure 10. The partition portion 103 is connected between the outer plate portion 101 and the inner plate portion 102, and divides the space between the outer plate portion 101 and the inner plate portion 102 into a plurality of resonance cavities 11. The connecting hole 12 is formed on the inner plate portion 102. Thus, a resonance cavity 11 is formed between the outer plate portion 101 and the inner plate portion 102, and the partition portion 103 divides the resonance cavity 11 into a plurality of separate resonance cavities 11. Different resonance cavities 11 can be set to absorb resonance cavities 11 of different frequency noises, thereby reducing the decibel of the compressor noise in the compressor assembly, improving the noise reduction capability of the box body 100, and improving the user experience of the air conditioner.

[0073] According to some optional embodiments of the present invention, referring to Figure 6 , Fig.10 and Fig.11 The outer plate 101 and the inner plate 102 are separate parts, the extension tube 20 and the inner plate 102 are integrally formed, and the first tube 30 and the outer plate 101 are integrally formed. Thus, the installation of the enclosure 10 can be facilitated, and at the same time, the processing and manufacturing of the outer plate 101 and the inner plate 102 can be facilitated.

[0088] When assembling the air conditioner, assemble the compressor assembly first. When assembling the compressor assembly, first install the liquid reservoir and the compressor on the mounting plate. The compressor and the liquid reservoir are connected by an air pipe. The compressor is connected to the outside of the box 100 through a power cord. Then assemble the box 100. When assembling the box 100, first assemble the enclosure 10. When assembling the enclosure 10, assemble the first tube 30 and the outer plate 101 integrally formed part on the rear side of the extension tube 20 and the inner plate 102 integrally formed part. Then, five enclosures 10 are assembled into a box 100 with an open bottom. It should be noted that the connecting hole 12 should face the mounting cavity. Then, the box 100 cover is set on the upper side of the compressor and the liquid reservoir. The box 100 and the mounting plate form a closed whole. It should be noted that the air pipe and the power cord should extend from the reserved holes of the box 100. At this time, the compressor assembly is installed.

[0089] When the air conditioner is running, the compressor will generate noise, and the noise will enter the resonance cavity 11 from the extension tube 20 through the connecting hole 12. After entering the resonance cavity 11, the noise will enter the first channel 51 from the extension tube 20 and continue to propagate. Then, the noise will enter the deepest part of the resonance cavity 11 from the front end of the first channel 51. When the noise propagates in the resonance cavity 11, the air in the resonance cavity 11 will move, and the noise will resonate with the resonance cavity 11 in the resonance cavity 11. The resonance cavity 11 can absorb the noise, and the housing 100 can reduce the decibel of the noise generated by the compressor, thereby improving the user experience of the air conditioner.

[0090] In order to achieve better noise reduction effect, the resonance absorption frequency band of the resonance cavity 11 can be controlled by controlling the volume of different resonance cavities 11, the length and diameter of the extension tube 20, and the length and diameter of the first tube 30, so that it can act on different frequency bands of the compressor noise respectively, and further by analyzing the noise frequency at different positions of the compressor, the arrangement of the resonance cavity 11 is reasonably optimized, and more low-frequency resonance cavities 11 are arranged at the positions where low-frequency noise is concentrated, such as the positions of the air pipe, rotor, motor and liquid reservoir, and more high-frequency resonance cavities 11 are arranged at the positions where high-frequency noise is concentrated, such as the exhaust position, to achieve targeted and effective absorption, reduce the reflection and leakage of sound waves in the cavity of the resonance cavity 11, and finally, through the superposition of the absorption spectrum in the whole range, the overall module absorption coefficient reaches above 0.6, so as to achieve maximum noise reduction.

[0091] The air conditioner of the embodiment of the present invention is provided with the compressor assembly of the above-mentioned second embodiment, the housing 100 of the first aspect is provided on the compressor assembly, and the resonance cavity 11 is provided on the housing 100 of the first aspect. The resonance cavity 11 can absorb noise, reduce the decibel of noise, and improve the noise reduction ability of the housing 100, thereby improving the use experience of the air conditioner. At the same time, an extension pipe 20 is provided at the position of the connecting hole 12. The extension pipe 20 can guide the noise from the installation cavity into the resonance cavity 11. At the same time, the extension pipe 20 can also increase the propagation distance of the noise in the resonance cavity 11, thereby reducing the frequency band of the noise, making the frequency band of the noise adapt to the noise reduction frequency band of the resonance cavity 11, thereby To ensure the noise reduction effect, by setting a first tube 30 fixed to the second inner wall 112 and sleeved on the outside of the extension tube 20, the first tube 30 and the extension tube 20 cooperate to form a first channel 51, which can further increase the propagation distance of the noise in the resonance cavity 11, thereby further reducing the frequency band of the noise, making the frequency band of the noise adapt to the noise reduction frequency band of the resonance cavity 11, so that noise in a larger frequency band can be reduced in the resonance cavity 11, further improving the noise reduction effect of the box 100, and at the same time, in a limited resonance cavity 11, the resonance cavity 11 can achieve lower frequency noise absorption, and can also reduce the volume of the resonance cavity 11, which is convenient for the production and application of the box 100.

[0092] Embodiment 2:

[0093] like Fig.10 and Fig.11 As shown, the structure of this embodiment is substantially the same as that of the first embodiment, wherein the same components are marked with the same reference numerals, and the only difference is that: the box body 100 described in the first embodiment is provided with one first tube 30, while the box body 100 described in the second embodiment is provided with two first tubes 30 and one second tube 40. The first tube 30 and the second tube 40 are alternately arranged from the inside to the outside in the radial direction, the front end of the second tube 40 is fixed to the first inner wall 111 and the rear end is spaced apart from the second inner wall 112, the second tube 40 is arranged radially outside the first tube 30 and spaced apart from the outer wall of the first tube 30, the inner wall of the second tube 40 and the outer wall of the first tube 30 define a second channel 52, the second channel 52 is communicated with the first channel 51, another first tube 30 is provided radially outside the second tube 40, the inner wall of the first tube 30 and the outer wall of the second tube 40 define a third channel 53, the third channel 53 is communicated with the second channel 52.

[0094] When the air conditioner is running, the compressor will generate noise, and the noise will enter the resonance cavity 11 from the extension tube 20 through the connecting hole 12. After entering the resonance cavity 11, the noise will enter the first channel 51 from the extension tube 20 and continue to propagate. Then, the noise will enter the second channel 52 from the front end of the first channel 51, and then the noise will propagate from front to back in the second channel 52. When the noise reaches the rear end of the second channel 52, the noise will then enter the third channel 53, and the noise will propagate from back to front in the third channel 53. Finally, the noise will enter the deepest part of the resonance cavity 11 from the front end of the third channel 53. When the noise propagates in the resonance cavity 11, it will cause the air in the resonance cavity 11 to move, and the noise will resonate with the resonance cavity 11 in the resonance cavity 11. The resonance cavity 11 can absorb the noise, and the cabinet 100 can reduce the decibel of the noise generated by the compressor, thereby improving the user experience of the air conditioner.

[0095] Compared with the air conditioner of the first embodiment, the air conditioner of this embodiment has noise passing through the interior of the extension tube 20, the first channel 51, the second channel 52 and the third channel 53 in sequence, and the propagation distance of the noise in the resonance cavity 11 is further lengthened, so that the frequency range of the noise absorbed by the box 100 can be further expanded, which can further improve the noise reduction effect of the box 100, allowing the air conditioner to run more quietly, thereby improving the user experience of the air conditioner. In addition, the number of the first tube 30 and the second tube 40 can also be designed as a plurality of first tubes 30 and a plurality of second tubes 40 according to the specific structural dimensions, so as to increase the flexibility of adjusting the noise reduction frequency of the resonance cavity 11.
