[0049] 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.

[0050] Please refer to the following Figure 1-Figure 11 A cabinet 100 according to an embodiment of the present invention is described.

[0051] Reference Figure 1 , Figure 5 and Figure 8 According to the box body 100 of the first embodiment of the present invention, the box body 100 can be applied to the compressor 200 assembly, and the box body 100 includes: a plurality of enclosures 10, the plurality of enclosures 10 enclose a compressor 200 installation cavity 110, and the compressor 200 and the liquid reservoir 300 can be installed in the compressor 200 installation cavity 110. At least one enclosure 10 has a resonance cavity 11 and a communication hole 12, that is, one, two, or three or more enclosures 10 can have a resonance cavity 11 and a communication hole 12, and the resonance cavity 11 is connected to the compressor 200 installation cavity 110 through the communication hole 12.

[0052] When the compressor 200 is running in the housing 100, the noise generated by the compressor 200 can enter the resonance cavity 11 from the connecting hole 12. In the resonance cavity 11, 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 the 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 noise reduction. In this way, the noise of the compressor 200 components can be reduced from being transmitted to the outside, and the decibel of the noise of the compressor 200 heard by the outside world is reduced. Therefore, the resonance cavity 11 can absorb noise, reduce the decibel of noise, improve the noise reduction ability of the housing 100, and enable the compressor 200 components to run relatively quietly, thereby improving the user experience of the air conditioner.

[0053] According to the embodiment of the present invention, the cabinet 100 is provided with a connecting hole 12 and a resonance cavity 11. Noise can enter the resonance cavity 11 from the connecting hole 12. The resonance cavity 11 can absorb the noise and reduce the decibel of the noise of the compressor 200 in the compressor 200 assembly, thereby ensuring the noise reduction capability of the cabinet 100 and improving the user experience of the air conditioner.

[0054] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , the resonance frequency range of the box 100 is 100 Hz-4000 Hz. Therefore, the box 100 can absorb the noise of the compressor 200 at a frequency of 100 Hz-4000 Hz.

[0055] 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.

[0056] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 The housing 100 has a plurality of resonance cavities 11 and a plurality of communication holes 12 corresponding to the plurality of resonance cavities 11. That is, the housing 100 may have two, three, four or more resonance cavities 11 and communication holes 12 corresponding to the resonance cavities 11. In this way, the plurality of resonance cavities 11 can enhance the noise absorption capability of the housing 100, further reduce the decibel of the noise, and improve the user experience of the air conditioner.

[0057] 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 aC 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 of the resonator can achieve adjustment in a wider frequency range, increasing the degree of freedom of adjustment of the box 100.

[0058] 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 200 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 range of the noise absorbed by the box 100, and effectively reducing the noise in multiple frequency bands generated by the compressor 200.

[0059] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 The enclosure 10 has a plurality of resonance cavities 11 and a plurality of communication holes 12 corresponding to the plurality of resonance cavities 11. In this way, a plurality of resonance cavities 11 and a plurality of communication holes 12 corresponding to the plurality of resonance cavities 11 are provided on each enclosure 10. When the compressor 200 generates noise during operation, the noise generated at any position of the compressor 200 can enter the resonance cavity 11 through the communication holes 12, thereby improving the noise reduction capability of the box 100.

[0060] For example, Figure 5 and Figure 8 As shown, taking the rear side enclosure 10 as an example, a plurality of resonance cavities 11 are arranged at intervals along the vertical direction, and the communication hole 12 is provided at the front side of the resonance cavity 11. Taking the upper side enclosure 10 as an example, a plurality of resonance cavities 11 are arranged at intervals along the front-back direction, and the communication hole 12 is provided at the lower side of the resonance cavity 11. In this way, the noise generated by different positions of the compressor 200 can enter the resonance cavity 11, and the resonance cavity 11 reduces the noise, thereby improving the noise reduction capability of the box 100.

[0061] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 , the resonance frequency ranges of at least two resonance cavities 11 are different, that is, the resonance frequency ranges of two, three, four or more resonance cavities 11 may be different. In this way, the resonance frequency range of the resonance cavity 11 can be expanded, and the noises of different frequencies generated by the operation of the compressor 200 can be absorbed by the box 100, thereby further improving the noise absorption capacity of the box 100.

[0062] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 The volumes of any two resonance cavities 11 are the same or different. The volumes of the resonance cavities 11 can be arranged according to the installation space in the installation cavity 110, so that the structural arrangement in the installation cavity 110 can be more reasonable.

[0063] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 , at least two resonance cavities 11 have different volumes, that is, the volumes of two, three, four or more resonance cavities 11 may be different. In this way, the 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.

[0064] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 , the depths of any two resonance cavities 11 are the same or different. If the depths of any two resonance cavities 11 are the same, the noise propagation distance in the resonance cavity 11 is the same, which will make the frequency of the noise absorbed by the resonance cavity 11 the same; if the depths of any two resonance cavities 11 are different, the noise propagation distance in the resonance cavity 11 is different, which will expand the frequency range of the noise absorbed by the box 100, thereby improving the noise reduction ability of the box 100.

[0065] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 , in the thickness direction of the enclosure 10 (such as Figure 5 In the front-to-rear direction of the rear side panel 10 shown in FIG. 1 , 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 110, so that the structural arrangement in the installation cavity 110 can be more reasonable.

[0066] According to some embodiments of the present invention, referring to Figure 1 and Figure 4, the resonance frequency interval of the housing 100 includes a plurality of 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 a plurality of 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 noise absorbed by the plurality of interval units constitute the interval range of the resonance frequency, and when the compressor 200 is running, the noise of the compressor 200 can be reduced in the resonance cavities 11 of different resonance frequencies, thereby improving the noise reduction effect of the housing 100.

[0067] 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, 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 200 is running, the position of the motor and rotor of the compressor 200 and the position of the liquid storage 300 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.

[0068] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 The box 100 may further include an extension tube 20, which is connected to the periphery of the connection hole and extends along the central axis of the connection hole. In this way, the extension tube 20 can adjust the distance of sound transmission, thereby adjusting the resonance frequency of the resonance cavity 11.

[0069] According to some optional embodiments of the present invention, referring to Figure 5 and Figure 8 , the extension tube 20 is located in the resonance cavity 11. In this way, the extension tube 20 extends into the resonance cavity 11, and the noise continues to propagate in the extension tube 20 after passing through the connecting hole 12, so that the noise can be guided to propagate along the direction of the extension tube 20, so that the propagation distance of the noise in the resonance cavity 11 can be controlled, so that the sound energy of the noise is reduced within the noise reduction frequency band of the resonance cavity 11.

[0070] Furthermore, if Figure 5 and Figure 8As shown, the extension tube 20 is located in the installation cavity 110 of the compressor 200. In this way, the noise can first enter the extension tube 20 from the tube mouth of the extension tube 20, and continue to propagate in the extension tube 20 after passing through the connecting hole 12, so that the propagation direction of the noise in the extension tube 20 can be controlled, and the propagation path of the noise can be controlled in the resonance cavity 11, so that the frequency of the noise is reduced to the noise reduction frequency band of the resonance cavity 11, and the noise reduction effect is ensured.

[0071] For example, Figure 8 As shown, a portion of the extension tube 20 is located in the resonance cavity 11 , and another portion of the extension tube 20 is located in the installation cavity 110 of the compressor 200 , which can increase the propagation distance of the noise in the extension tube 20 , thereby ensuring the noise reduction effect of the box 100 .

[0072] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 The housing 100 has a plurality of resonance cavities 11 and a plurality of communication holes 12, and the lengths of the extension tubes 20 at the positions of at least two communication holes 12 are different. Therefore, the length of the extension tube 20 can be reasonably designed according to the space in the installation cavity 110, so as to ensure that the housing 100 can cover the compressor 200 and the liquid accumulator 300 in the installation cavity 110.

[0073] According to some embodiments of the present invention, referring to Figure 8 and Fig. 9 The cross section of the extension tube 20 is circular or polygonal. In this way, the design freedom of the extension tube 20 can be increased, and various design requirements can be met.

[0074] For example, Figure 8 As shown, the cross section of the extension tube 20 can be circular, rectangular, triangular, or five-pointed star or other shapes, which can increase the design freedom of the cross section of the extension tube 20.

[0075] According to some embodiments of the present invention, referring to Figure 1 , Figure 4 and Figure 5 , multiple panels 10 enclose a compressor 200 installation cavity 110 with an open bottom. In this way, after the compressor 200 is installed, the box body 100 composed of multiple panels 10 is directly covered on the upper side of the compressor 200, so that the installation of the box body 100 can be facilitated.

[0076] For example, Figure 4As shown, a total of five enclosures 10 are provided, and the five enclosures 10 enclose a box body 100 with an open lower portion, and the box body 100 is covered on the upper side of the mounting plate 600, and the box body 100 cooperates with the mounting plate 600 to form a closed mounting cavity 110. When assembling the air conditioner, the compressor 200 and the liquid accumulator 300 are first installed on the mounting plate 600, and then the box body 100 composed of a plurality of enclosures 10 is covered on the upper side of the compressor 200, and the box body 100 and the mounting plate 600 form a closed whole, so that the compressor 200 and the liquid accumulator 300 can be protected in the mounting cavity 110.

[0077] According to some embodiments of the present invention, referring to Figure 5 and Figure 4 The enclosure 10 includes: an outer plate 101, an inner plate 102 and a partition 103. The outer plate 101 and the inner plate 102 are arranged at intervals along the thickness direction of the enclosure 10. The partition 103 is connected between the outer plate 101 and the inner plate 102, and divides the space between the outer plate 101 and the inner plate 102 into a plurality of resonance cavities 11. The connecting hole 12 is formed on the inner plate 102. Thus, the outer plate 101 and the inner plate 102 form the side walls of the resonance cavity 11, and the partition 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 frequencies, so that the decibel of the noise of the compressor 200 in the compressor 200 assembly can be reduced, the noise reduction capability of the box 100 can be improved, and the use experience of the air conditioner can be improved.

[0078] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 , the thickness of any one of the outer plate 101, the inner plate 102 and the partition 103 is 1mm-3mm, that is, the thickness of the outer plate 101, the inner plate 102 or the partition 103 can be 1mm-3mm. In this way, the structural strength of the box body 100 can be ensured to prevent the box body 100 from being damaged. At the same time, the volume of the resonance cavity 11 can be reduced due to the excessive thickness of any one of the outer plate 101, the inner plate 102 and the partition 103, thereby facilitating the arrangement of the resonance cavity 11.

[0079] For example, Figure 1 As shown, the thickness of any one of the outer plate 101 , the inner plate 102 and the partition plate 103 may be 1 mm, 1.5 mm, 2.0 mm, 2.5 mm or 3 mm.

[0080] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The box body 100 is integrally formed. In this way, the overall strength of the box body 100 can be ensured and the box body 100 can be prevented from being damaged.

[0081] The compressor 200 assembly according to the second aspect of the present invention is shown in FIG. Figure 1 and Figure 7 The compressor 200 assembly includes a compressor 200, a liquid reservoir 300 and a housing 100 of the first aspect of this embodiment. The compressor 200 and the liquid reservoir 300 are both disposed in the installation cavity 110 of the compressor 200.

[0082] When the compressor 200 assembly is running, the compressor 200 generates noise, and the frequency bands of the noise generated at different positions of the compressor 200 are inconsistent. The noise is relatively large at the rotor and motor of the compressor 200. The circulation of the refrigerant between the accumulator 300 and the compressor 200 also generates noise, and the noise level of the refrigerant circulation changes with the power of the air conditioner. A low-frequency resonance cavity 11 is arranged at the rotor and motor of the compressor 200 and at the circulation position of the refrigerant.

[0083] According to the compressor 200 assembly of an embodiment of the present invention, by setting the box body 100 of the first aspect embodiment mentioned above, a connecting hole 12 and a resonance cavity 11 are set on the box body 100 of the first aspect, and the noise of the compressor 200 can enter the resonance cavity 11 from the connecting hole 12. The resonance cavity 11 can absorb the noise and reduce the decibel of the noise of the compressor 200 in the compressor 200 assembly, thereby ensuring the noise reduction ability of the box body 100, thereby improving the user experience of the air conditioner.

[0084] The air conditioner according to the third aspect of the present invention comprises the compressor 200 assembly according to the second aspect of the present embodiment.

[0085] According to the air conditioner of the embodiment of the present invention, by setting the compressor 200 component of the above-mentioned second aspect embodiment, the box body 100 of the first aspect is set on the compressor 200 component, and the connecting hole 12 and the resonance cavity 11 are set on the box body 100 of the first aspect. The noise of the compressor 200 can enter the resonance cavity 11 from the connecting hole 12, and the resonance cavity 11 can absorb the noise, reduce the decibel of the noise of the compressor 200 in the compressor 200 component, ensure the noise reduction ability of the box body 100, thereby improving the user experience of the air conditioner.

[0092] When assembling the air conditioner, assemble the compressor 200 assembly first. When assembling the compressor 200 assembly, first install the liquid reservoir 300 and the compressor 200 on the mounting plate 600. The compressor 200 and the liquid reservoir 300 are connected by the air pipe 400. The compressor 200 is connected to the outside of the box 100 through the power cord 500. Then, the 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 110. Then, the box 100 cover is set on the upper side of the compressor 200 and the liquid reservoir 300. The box 100 and the mounting plate 600 form a closed whole. It should be noted that the air pipe 400 and the power cord 500 should extend out from the reserved holes of the box 100. At this time, the compressor 200 assembly is installed.

[0093] When the air conditioner is running, the compressor 200 generates noise, and the noise enters the resonance cavity 11 from the extension tube 20 through the connecting hole 12. After the noise enters the resonance cavity 11, the air in the resonance cavity 11 moves, and the noise resonates with the resonance cavity 11 inside 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 200, thereby improving the user experience of the air conditioner.

[0094] In order to achieve a better noise reduction effect, the volume of different resonance cavities 11 can be controlled to control the resonance absorption frequency band of the resonance cavity 11, so that it can act on different frequency bands of the compressor 200 noise respectively, and further by analyzing the noise frequency at different positions of the compressor 200, the resonance cavity 11 is reasonably optimized and arranged. At the low-frequency noise concentration positions, such as the positions of the air pipe 400, the rotor, the motor and the liquid storage tank 300, more low-frequency resonance cavities 11 are arranged, and at the high-frequency concentration positions, such as the exhaust position, more high-frequency resonance cavities 11 are arranged, so as to achieve targeted and effective absorption, reduce the reflection and leakage of sound waves in the resonance cavity 11, and finally, by superimposing the absorption spectrum in the whole range, the overall module absorption coefficient reaches above 0.6, so as to achieve maximum noise reduction.

[0095] The air conditioner of the embodiment of the present invention is provided with the compressor 200 assembly of the second embodiment, the housing 100 of the first aspect is provided on the compressor 200 assembly, and the connecting hole 12 and the resonance cavity 11 are provided on the housing 100 of the first aspect. The noise of the compressor 200 can enter the resonance cavity 11 from the connecting hole 12, and the resonance cavity 11 can absorb the noise, reduce the decibel of the noise of the compressor 200 in the compressor 200 assembly, ensure the noise reduction ability of the housing 100, and thus improve the use experience of the air conditioner. In addition, by adjusting the length of the extension tube 20, the propagation distance of the noise in the resonance cavity 11 can be adjusted, so that the frequency band of the noise can be matched with the noise reduction frequency band of the resonance cavity 11, thereby further improving the noise reduction effect.

[0096] Embodiment 2:

[0097] 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 inner plate 102 described in the first embodiment is not a flat plane due to the different depths of the resonance cavity 11, resulting in the inner plate 102 of the front side panel 10, the rear side panel 10, the left side panel 10 and the right side panel 10, while the resonance cavity 11 described in the second embodiment has the same depth, so that the inner plate 102 of the front side panel 10, the rear side panel 10, the left side panel 10 and the right side panel 10 is a flat plane.

[0098] Compared with the air conditioner of the first embodiment, the air conditioner of this embodiment has an inner plate 102 which is a flat surface. When the box body 100 is placed on the upper side of the compressor 200 and the liquid reservoir 300, it can be installed more conveniently without having to pay extra attention to whether the inner plate 102 collides with the compressor 200 or the liquid reservoir 300, thereby improving installation efficiency and saving installation time.
