Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0054] The technical solution of this application is as follows:

[0055] Firstly, please refer to Figures 1-4 This application provides a compressor chamber 100. The compressor chamber 100 includes a compressor chamber body 10 and a compressor 20 disposed within the compressor chamber body 10. The compressor chamber 100 also includes a sound-absorbing panel 30, which is movably and / or rotatably disposed within the compressor chamber body 10 to absorb noise within the compressor chamber body 10.

[0056] The sound-absorbing panel 30 in the press chamber 100 described in this application can be moved to a noisier area, or rotated to approach a noisier area, or moved to a noisier area and rotated to approach a noisier area, depending on the noise level of different areas within the press chamber body 10. In this way, a better sound absorption and noise reduction effect can be achieved.

[0057] In some embodiments, the compressor compartment 100 further includes a condenser fan 101 disposed within the compressor compartment body 10, the condenser fan 101 being used to cool the compressor 20. It is understood that the condenser fan 101 is also a source of noise within the compressor compartment body 10.

[0058] In some embodiments, the press chamber body 10 includes a top plate 11, a bottom plate 12 opposite to the top plate 11, and at least one side plate 13 connecting the top plate 11 and the bottom plate 12. In some embodiments, the press chamber body 10 includes four interconnected side plates 13.

[0059] The sound-absorbing panel 30 is movably and / or rotatably disposed on the top plate 11, or the bottom plate 12, or the side plate 13. In other words, in some embodiments, the sound-absorbing panel 30 is movably and / or rotatably disposed on the top plate 11; in other embodiments, the sound-absorbing panel 30 is movably and / or rotatably disposed on the bottom plate 12; and in still other embodiments, the sound-absorbing panel 30 is movably and / or rotatably disposed on one side plate 13.

[0060] It should be noted that, taking the sound-absorbing panel 30 being disposed on the side panel 13 as an example, the movement of the sound-absorbing panel 30 described in this application refers to translation in the plane where the sound-absorbing panel 30 is located, or movement relative to the side panel 13 towards or away from it.

[0061] It should be noted that the rotation of the sound-absorbing panel 30 described in this application refers to rotation about any straight line in the plane containing the sound-absorbing panel 30 as an axis. In at least one embodiment, the rotation of the sound-absorbing panel 30 refers to rotation of the sound-absorbing panel 30 around one of its own side surfaces (see [reference]). Figure 4 ).

[0062] In some embodiments, the sound-absorbing panel 30 is disposed on the top plate 11 and parallel to the top plate 11. In other embodiments, the sound-absorbing panel 30 is disposed on the bottom plate 12 and parallel to the bottom plate 12. In still other embodiments, the sound-absorbing panel 30 is disposed on a side plate 13 and parallel to the side plate 13.

[0063] In some embodiments, the rotatable angle of the sound-absorbing panel 30 is 0° to 45°, for example, 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, and any range between two of these values. Within this range, noise absorption is beneficial.

[0064] It is understood that the number of sound-absorbing panels 30 can be one or more. It is understood that when there are multiple sound-absorbing panels 30, the positions of the multiple sound-absorbing panels 30 can be the same or different. In other words, the multiple sound-absorbing panels 30 can be set on the same inner wall of the compressor chamber body 10 or on different inner walls.

[0065] In some embodiments, the press chamber 100 further includes a noise monitoring device 40, a noise analysis device 50, and a controller 60 disposed within the press chamber body 10.

[0066] The noise monitoring device 40 is mounted on the top plate 11, the bottom plate 12, or the side plate 13. The noise analysis device 50 is mounted on the top plate 11, the bottom plate 12, or the side plate 13. The controller 60 is mounted on the top plate 11, the bottom plate 12, or the side plate 13.

[0067] In at least some embodiments, the sound-absorbing panel 30 and the noise monitoring device 40 are respectively disposed on two opposite side walls of the compressor chamber body 10.

[0068] The noise monitoring device 40 is used to monitor the noise in each area inside the compressor chamber body 10 and transmit the monitored noise to the noise analysis device 50.

[0069] In some embodiments, the noise monitoring device 40 includes at least two sound sensors 41, each sound sensor 41 for monitoring noise within a region of the compressor chamber body 10. In at least one embodiment, different sound sensors 41 monitor different regions.

[0070] The noise analysis device 50 is used to receive the noise in each area of ​​the press chamber body 10 monitored by the noise monitoring device 40, compare and analyze the noise level in each area of ​​the press chamber body 10, and transmit the signal of the area with the highest noise in the press chamber body 10 to the controller 60.

[0071] The controller 60 is used to receive a signal from the noise analysis device 50 indicating that a certain area within the press chamber body 10 has the highest noise level, and to control the sound-absorbing plate 30 to move to the area with the highest noise level within the press chamber body 10, and / or to control the sound-absorbing plate 30 to rotate to approach the area with the highest noise level within the press chamber body 10.

[0072] In some embodiments, the controller 60 controls the sound-absorbing panel 30 to move to a noisy area, or controls the sound-absorbing panel 30 to rotate to get closer to the noisy area, or controls the sound-absorbing panel 30 to move to a noisy area and rotate to get closer to the noisy area. In this way, a better sound absorption and noise reduction effect can be achieved.

[0073] In some embodiments, the press chamber 100 further includes a drive device 70 disposed within the press chamber body 10, and the controller 60 is used to control the drive device 70 to drive the sound-absorbing plate 30, and the drive device 70 is used to drive the sound-absorbing plate 30 to move and / or rotate.

[0074] In some embodiments, the driving device 70 may include a first driving device and a second driving device, wherein the first driving device is used to drive the sound-absorbing panel 30 to move, and the second driving device is used to drive the sound-absorbing panel 30 to rotate.

[0075] In some embodiments, the drive device 70 includes a servo motor.

[0076] In some embodiments, please refer to Figure 2The internal space of the compressor chamber body 10 is divided into three noise monitoring zones 1 to 3 (i.e., noise monitoring zone 1, noise monitoring zone 2, and noise monitoring zone 3). The noise monitoring device 40 includes three sound sensors 41, which are respectively located in noise monitoring zones 1, 2, and 3. At least one side panel 13 includes a first side panel 131 and a second side panel 132 facing each other. The three sound sensors 41 are respectively disposed on the first side panel 131, and the sound-absorbing panel 30 is disposed on the second side panel 132.

[0077] Please see Figure 3 Taking the area with the highest noise level in noise monitoring zone 1 as an example, when the press chamber 100 is working, the noise monitoring device 40 starts and monitors the noise of the press chamber body 10, and transmits the monitored noise to the noise analysis device 50; the noise analysis device 50 receives the noise of each area in the press chamber body 10 monitored by the noise monitoring device 40, compares and analyzes the noise level of each area in the press chamber body 10, and transmits the signal that noise monitoring zone 1 is the area with the highest noise level to the controller 60; the controller 60 receives the pressure signal transmitted by the noise analysis device 50 and controls the drive device 70 to drive the sound-absorbing plate 30 to move into the noise monitoring zone 1.

[0078] Please see Figure 4 After the sound-absorbing panel 30 moves into the noise monitoring area 1, the driving device 70 can also drive the sound-absorbing panel 30 to rotate, so that as much of the sound-absorbing panel 30 as possible is closer to the noise-strong area, so as to absorb sound and reduce noise more effectively.

[0079] Please see Figures 2-4 In some embodiments, the press chamber 100 further includes a composite sound-absorbing layer 80, which may be disposed on the inner wall of the top plate 11, and / or the inner wall of the bottom plate 12, and / or the inner wall of the side plate 13, and / or the surface of the sound-absorbing plate 30.

[0080] Please see Figures 5-7 In some implementations, the composite sound-absorbing layer 80 includes at least one layer of sound-absorbing cotton 81 and at least one layer of microporous material 82. The absolute value of the difference between the number of layers of the sound-absorbing cotton 81 and the number of layers of the microporous material 82 is 0 or 1. The sound-absorbing cotton 81 and the microporous material 82 are alternately stacked.

[0081] In some embodiments, the composite sound-absorbing layer 80 includes m layers of sound-absorbing cotton 81 and n layers of microporous material 82, wherein the absolute value of the difference between m and n is 0 or 1, and the m layers of sound-absorbing cotton 81 and the n layers of microporous material 82 are alternately stacked.

[0082] In some embodiments, the material of the sound-absorbing cotton layer 81 is a sound-absorbing cotton known for sound absorption and noise reduction, such as, but not limited to, one or more of foam and mineral wool.

[0083] In some embodiments, the material of the microporous material layer 82 is a known microporous material used for sound absorption and noise reduction, such as, but not limited to, one or more of aluminum, aluminum alloy, ceramic, wood board, and glass fiber.

[0084] In some embodiments, the sound-absorbing cotton layer 81 is mainly used to absorb high-frequency noise, and the microporous material layer 82 is mainly used to absorb mid-to-low-frequency noise. It is understood that the high-frequency noise has a frequency range greater than 500Hz and less than or equal to 20kHz, and the mid-to-low-frequency noise has a frequency range of 20–500Hz. Thus, the composite sound-absorbing layer 80 can absorb both high-frequency and low-frequency noise, thereby achieving a better sound absorption and noise reduction effect.

[0085] In some embodiments, the side of the composite sound-absorbing layer 80 away from the inner wall of the compressor chamber body 10 is a sound-absorbing cotton layer 81. In other embodiments, the side of the composite sound-absorbing layer 80 away from the inner wall of the compressor chamber body 10 is a microporous material layer 82. Since the main noise generated by the condenser fan 101 and the compressor 20 is low to medium frequency, having a microporous material layer 82 on the side of the composite sound-absorbing layer 80 away from the inner wall of the compressor chamber body 10 can preferentially absorb low to medium frequency noise before absorbing high frequency noise, which is beneficial for effective sound absorption and noise reduction.

[0086] The microporous material layer 82 has a plurality of micropores, the pore size of which is 500μm to 2mm, for example, 500μm, 600μm, 700μm, 800μm, 900μm, 1mm, 1.5mm, 2mm, and any range between any two of these values. Within this pore size range, it is beneficial to absorb low- to mid-frequency noise.

[0087] In some embodiments, the thickness of the sound-absorbing cotton layer 81 is 10 to 20 mm, for example, 10 mm, 12 mm, 15 mm, 16 mm, 18 mm, 20 mm, and any range between any two of the above values.

[0088] In some embodiments, the thickness of the microporous material layer 82 is 5 to 50 mm, for example, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, and any range between any two of the above values.

[0089] In some embodiments, the thickness of each sound-absorbing cotton layer 81 in the composite sound-absorbing layer 80 is the same; or, the thickness of each sound-absorbing cotton layer 81 increases or decreases sequentially along the direction close to the inner wall of the compressor chamber body 10. It is understood that the greater the thickness of the sound-absorbing cotton layer 81, the lower the frequency of noise it can absorb. Therefore, by sequentially increasing or decreasing the thickness of each sound-absorbing cotton layer 81 along the direction close to the inner wall of the compressor chamber body 10, each sound-absorbing cotton layer 81 can specifically absorb noise in different frequency ranges, which is beneficial for achieving full-frequency noise absorption and thus effectively improving the noise absorption effect. In at least one preferred embodiment, the thickness of each sound-absorbing cotton layer 81 decreases sequentially along the direction close to the inner wall of the compressor chamber body 10, thus absorbing noise more effectively.

[0090] In some embodiments, the thickness of each microporous material layer 82 in the composite sound-absorbing layer 80 is the same; or, the thickness of each microporous material layer 82 increases or decreases sequentially along the direction close to the inner wall of the compressor chamber body 10. It is understood that the greater the thickness of the microporous material layer 82, the lower the frequency of noise it can absorb. Therefore, by sequentially increasing or decreasing the thickness of each microporous material layer 82 along the direction close to the inner wall of the compressor chamber body 10, each microporous material layer 82 can specifically absorb noise in different frequency ranges, which is beneficial for achieving full-band noise absorption and thus effectively improving the noise absorption effect. In at least one preferred embodiment, the thickness of each microporous material layer 82 decreases sequentially along the direction close to the inner wall of the compressor chamber body 10, thus absorbing noise more effectively.

[0091] In some embodiments, the composite sound-absorbing layer 80 has layers of equal thickness; or, the thickness of each layer increases or decreases sequentially along the direction close to the inner wall of the compressor chamber body 10. It is understood that a greater thickness allows for the absorption of lower frequency noise. Therefore, the sequential increase or decrease in thickness of each layer along the direction close to the inner wall of the compressor chamber body 10 allows each layer to specifically absorb noise within different frequency ranges, facilitating full-frequency noise absorption and effectively improving noise absorption. In at least one preferred embodiment, the thickness of each layer in the composite sound-absorbing layer 80 decreases sequentially along the direction close to the inner wall of the compressor chamber body 10, thus absorbing noise more effectively.

[0092] Please see Figure 8In some embodiments, the composite sound-absorbing layer 80 includes at least one first microporous material layer 801, at least one second microporous material layer 802, and at least one third microporous material layer 803, wherein the first microporous material layer 801, the second microporous material layer 802, and the third microporous material layer 803 are alternately stacked in sequence, and the second microporous material layer 802 is located between the first microporous material layer 801 and the third microporous material layer 803.

[0093] In some embodiments, the thickness of the first microporous material layer 801, the thickness of the second microporous material layer 802, and the thickness of the third microporous material layer 803 are each independently 5 to 50 mm, for example, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, and the range between any two of the above values.

[0094] In some embodiments, the pore size of the micropores in the first microporous material layer 801 is 1 μm to 100 μm, for example, 1 μm, 10 μm, 20 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, 100 μm, and any range between two of these values. Within this pore size range, it is beneficial to absorb noise with a frequency of 2 kHz to 20 kHz, i.e., high-frequency noise.

[0095] In some embodiments, the pore size of the micropores in the second microporous material layer 802 can be greater than 100 μm and less than 500 μm, for example, 110 μm, 150 μm, 200 μm, 250 μm, 300 μm, 350 μm, 400 μm, 450 μm, 490 μm, and any range between these two values. Within this pore size range, it is beneficial to absorb noise with a frequency of 500 Hz to 2 kHz, i.e., higher frequency noise.

[0096] In some embodiments, the pore size of the micropores in the third microporous material layer 803 is 500 μm to 2 mm, for example, 500 μm, 600 μm, 700 μm, 800 μm, 900 μm, 1 mm, 1.5 mm, 2 mm, and any range between two of these values. Within this pore size range, it is beneficial to absorb noise with a frequency of 20 Hz to 500 Hz, i.e., low to medium frequency noise.

[0097] In some embodiments, the side of the composite sound-absorbing layer 80 away from the inner wall of the compressor chamber body 10 is a first microporous material layer 801. In other embodiments, the side of the composite sound-absorbing layer 80 away from the inner wall of the compressor chamber body 10 is a third microporous material layer 803. Since the main noise generated by the condenser fan 101 and the compressor 20 is low to medium frequency, having the side of the composite sound-absorbing layer 80 away from the inner wall of the compressor chamber body 10 as the third microporous material layer 803 can preferentially absorb low to medium frequency noise before absorbing high frequency noise, which is beneficial for effective sound absorption and noise reduction.

[0098] In some embodiments, the thickness of each first microporous material layer 801 in the composite sound-absorbing layer 80 is the same; or, the thickness of each first microporous material layer 801 increases or decreases sequentially along the direction close to the inner wall of the compressor chamber body 10. It is understood that the greater the thickness of the first microporous material layer 801, the lower the frequency of noise it can absorb. Therefore, by sequentially increasing or decreasing the thickness of each first microporous material layer 801 along the direction close to the inner wall of the compressor chamber body 10, each first microporous material layer 801 can specifically absorb noise in different frequency ranges, which is beneficial for achieving full-band noise absorption and thus effectively improving the noise absorption effect. In at least one preferred embodiment, the thickness of each first microporous material layer 801 decreases sequentially along the direction close to the inner wall of the compressor chamber body 10, thus absorbing noise more effectively.

[0099] In some embodiments, the thickness of each second microporous material layer 802 in the composite sound-absorbing layer 80 is the same; or, the thickness of each second microporous material layer 802 increases or decreases sequentially along the direction close to the inner wall of the compressor chamber body 10. It is understood that the greater the thickness of the second microporous material layer 802, the lower the frequency of noise it can absorb. Therefore, by sequentially increasing or decreasing the thickness of each second microporous material layer 802 along the direction close to the inner wall of the compressor chamber body 10, each second microporous material layer 802 can specifically absorb noise in different frequency ranges, which is beneficial for achieving full-band noise absorption and thus effectively improving the noise absorption effect. In at least one preferred embodiment, the thickness of each second microporous material layer 802 decreases sequentially along the direction close to the inner wall of the compressor chamber body 10, thus absorbing noise more effectively.

[0100] In some embodiments, the thickness of each third microporous material layer 803 in the composite sound-absorbing layer 80 is the same; or, the thickness of each third microporous material layer 803 increases or decreases sequentially along the direction close to the inner wall of the compressor chamber body 10. It is understood that the greater the thickness of the third microporous material layer 803, the lower the frequency of noise it can absorb. Therefore, by sequentially increasing or decreasing the thickness of each third microporous material layer 803 along the direction close to the inner wall of the compressor chamber body 10, each third microporous material layer 803 can specifically absorb noise in different frequency ranges, which is beneficial for achieving full-band noise absorption and thus effectively improving the noise absorption effect. In at least one preferred embodiment, the thickness of each third microporous material layer 803 decreases sequentially along the direction close to the inner wall of the compressor chamber body 10, thus absorbing noise more effectively.

[0101] In some embodiments, the composite sound-absorbing layer 80 has layers of the same thickness; or, the thickness of each layer increases or decreases sequentially along the direction close to the inner wall of the compressor chamber body 10. It is understood that a greater thickness allows for the absorption of lower frequency noise. Therefore, the sequential increase or decrease in the thickness of each layer allows each layer to specifically absorb noise within different frequency ranges, facilitating full-frequency noise absorption and effectively improving noise absorption. In at least one preferred embodiment, the thickness of each layer in the composite sound-absorbing layer 80 decreases sequentially along the direction close to the inner wall of the compressor chamber body 10, thus absorbing noise more effectively.

[0102] Understandably, since microporous materials are relatively expensive, the composite sound-absorbing layer 80 is preferably composed of at least one sound-absorbing cotton layer 81 and at least one microporous material layer 82, in order to save costs.
