[0035] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] During operation, variable frequency drives (VFDs) cover a wide frequency range, which can easily generate multiple resonance points, resulting in significant noise. Currently, a common noise testing method involves placing noise sensors in four directions around the outside of the unit. However, even with this multi-directional noise detection approach, it remains difficult to quickly and accurately pinpoint the exact location of the noise anomaly.

[0037] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The air conditioner noise monitoring device provided by this utility model includes: a ring transmission assembly 1, a linear transmission assembly 2, and a noise sensor 3; the ring transmission assembly 1 is disposed on the inner or outer side of the outdoor unit 100; the linear transmission assembly 2 is vertically mounted on the ring transmission assembly 1 and moves with the ring transmission assembly 1; the noise sensor 3 is vertically mounted on the linear transmission assembly 2.

[0038] This invention, through the cooperation of the ring transmission component 1 and the linear transmission component 2, enables the noise sensor 3 to be flexibly adjusted in three-dimensional space, thereby allowing for the measurement of noise values ​​at different locations. Therefore, this invention can perform multi-directional noise value testing and quickly and accurately locate abnormal noise points.

[0039] It is understandable that, such as Figure 1 , Figure 2 As shown, the ring transmission assembly 1 can realize the movement of the noise sensor 3 in the X and Y axis directions, while the linear transmission assembly 2 can realize the movement of the noise sensor 3 in the Z axis direction.

[0040] In a further embodiment, the linear transmission assembly 2 and the ring transmission assembly 1 are provided with scale lines 4, which are used to conveniently determine the spatial position of the noise sensor 3.

[0041] This invention provides a scale line 4 on the linear transmission assembly 2 and the ring transmission assembly 1, which facilitates the precise determination of the spatial position of the noise sensor 3 by manual or software operation, and simultaneously and accurately obtains the magnitude of the noise value.

[0042] In a further embodiment, such as Figure 4 As shown, the annular transmission assembly 1 includes an annular guide rail 11 and multiple first drive motors 12. The first drive motors 12 are respectively located at the corners of the annular guide rail 11. Gears 13 are fixedly installed at the output ends of the first drive motors 12. The body of the annular guide rail 11 is provided with a toothed chain 14 that cooperates with the gears 13.

[0043] It is understandable that, such as Figure 4As shown, the outer side of the annular guide rail 11 is provided with scale lines 4, while the inner side of its body is equipped with a toothed chain 14. Four first drive motors 12 are located at the four corners of the annular guide rail 11, and each first drive motor 12 has a gear 13 installed at its output end. Through the synchronous drive of these four first drive motors 12, the gears 13 rotate accordingly, thereby driving the toothed chain 14 and the annular guide rail 11 to move together, thus achieving precise movement of the linear transmission assembly 2 and the noise sensor 3 in the X and Y axes. This utility model uses a motor 52 drive method to move the annular guide rail 11, which has a simple structure and is easy to implement.

[0044] In addition, the ring transmission assembly 1 also includes a support component for supporting and mounting components such as the ring guide rail 11 and the first drive motor 12.

[0045] In a further embodiment, such as Figure 4 As shown, the linear transmission assembly 2 includes a linear guide rail 21 and a second drive motor 22. The bottom end of the linear guide rail 21 is fixedly installed on the annular guide rail 11, and the top end of the linear guide rail 21 is provided with the second drive motor 22. The body of the linear guide rail 21 is provided with a push rod component 23, and the telescopic end of the push rod component 23 is provided with a noise sensor 3. Under the drive of the second drive motor 22, the push rod component 23 drives the noise sensor 3 to move up and down.

[0046] It is understandable that, such as Figure 4 As shown, the linear guide 21 has scale lines 4 on its outer side, while a push rod component 23 and a noise sensor 3 are located on its inner side. Furthermore, a second drive motor 22 is mounted on the top of the linear guide 21. The second drive motor 22 can be a stepper motor. This invention uses an electric actuator similar to an electric push rod to drive the noise sensor 3 to move; it has a simple structure and is easy to implement.

[0047] Please refer to the following: Figure 1 , Figure 5 The air conditioner provided by this utility model includes an outdoor unit 100 and an air conditioner noise monitoring device. The air conditioner can be an inverter air conditioner.

[0048] The noise monitoring device includes a ring transmission assembly 1, a linear transmission assembly 2, and a noise sensor 3. The ring transmission assembly 1 is located inside or outside the outdoor unit 100. The linear transmission assembly 2 is vertically mounted on the ring transmission assembly 1 and moves with it. The noise sensor 3 is vertically mounted on the linear transmission assembly 2. The noise sensor 3 of this invention achieves position adjustment through the ring transmission assembly 1 and the linear transmission assembly 2, enabling precise measurement of noise values ​​at different locations and thus accurately locating abnormal noise points in the air conditioner.

[0049] Understandably, the air conditioner noise monitoring device can be installed either on the outside or inside of the outdoor unit 100, suitable for noise reduction needs at different frequencies. This device is shipped with the product, allowing users to test noise levels themselves. It can also be set to automatically trigger an alarm when noise exceeds a preset threshold, promptly reminding users to take appropriate measures to reduce noise levels, thereby efficiently resolving noise problems and significantly improving user comfort.

[0050] In a further embodiment, such as Figure 5 As shown, the outdoor unit 100 is divided into a fan chamber 101 and a compressor chamber 102 by a partition 106. A ring-shaped transmission assembly 1 passes through the partition 106 and spans between the fan chamber 101 and the compressor chamber 102. It can be understood that the vibration sources of the outdoor unit 100 mainly include the compressor and the fan. The noise sensor 3 moves between the fan chamber 101 and the compressor chamber 102 using the ring-shaped transmission assembly 1 and the linear transmission assembly 2, thereby accurately measuring the maximum noise level.

[0051] In a further embodiment, the compressor chamber 102 is provided with a sound insulation and noise reduction device, thereby reducing the noise level in the compressor chamber 102 and improving the quietness performance of the entire air conditioning system.

[0052] In an alternative embodiment, such as Figure 5 , Figure 6 As shown, the press chamber 102 is enclosed by multiple side plates and partitions 106 to form a receiving space. The sound insulation and noise reduction device includes sound-insulating roller shutter assemblies 5 spaced apart at intervals on each side plate and partition 106. Figure 7 , Figure 8 As shown, the soundproof roller blind assembly 5 includes a roller blind rod 51, a motor 52, and a soundproof curtain 53. The top of the soundproof curtain 53 is mounted on the body of the roller blind rod 51. The motor 52 is fixedly installed at one end of the roller blind rod 51 and drives the roller blind rod 51 to rotate, so that the soundproof curtain 53 switches between an open state and a closed state. By setting the soundproof roller blind assembly 5, targeted soundproofing treatment can be carried out on the noise generated at different side panels and partitions 106, further improving the quietness performance of the entire air conditioning system.

[0053] It is understandable that, such as Figures 5 to 7As shown, the sound insulation and noise reduction device is built into the outdoor unit 100 and is shipped with the unit; users can test the noise level themselves. Two movable windows are opened on the partition 106. These windows open when the noise sensor 3 passes through the partition 106 and remain closed afterward. N sound insulation curtains 53 are designed at four locations on the compressor chamber 102: the front panel 103, the right side panel 104, the rear panel 105, and the partition 106. Each sound insulation curtain 53 corresponds to one motor 52; the curtain opens when the motor 52 rotates forward and retracts when it rotates backward. The sound insulation roller blind assembly 5 is mounted on the inside or outside of the air conditioner via a bracket. There is a certain coefficient relationship between the sound frequency and the compressor frequency, which can be written as f = qf. 压缩机 (q is a fixed coefficient, f is the sound frequency, f 压缩机 (where λ is the compressor's operating frequency); and according to the basic characteristics of sound waves λ = v / f (where v is a fixed value representing the speed of sound propagation in the sound insulation material, f is the sound frequency, and λ is the wavelength); the soundproof roller blind assembly can be considered as a sound-absorbing resonant cavity. Maintaining the length of the resonant cavity at 1 / 4 of the wavelength allows the sound waves to be 180 degrees out of phase, resulting in the maximum reduction effect. Therefore, H = nh = λ / 4 (where λ is the wavelength, h is the thickness of a single soundproof blind, and n is the number of blinds).

[0054] Greater than the set value (0, fmax) <![CDATA[H=nh=v / 4qf 压缩机 ]]> <![CDATA[n=v / 4qf 压缩机 h]]> Less than the set value (0, fmax) 0 0

[0055] Noise can be reduced in the following way: When the noise value detected by noise sensor 3 near partition 106, front panel 103, right side panel 104, or rear side panel 105 exceeds the standard, the system will automatically control the opening of the corresponding number of soundproof curtains 53 to achieve a noise reduction effect. Specifically, when the noise value detected by noise sensor 3 near partition 106 exceeds the standard, the system controls the opening of n soundproof roller blinds to achieve a noise reduction effect.

[0056] When the noise level detected by noise sensor 3 near the front panel 103 exceeds the limit, the system controls the opening of n soundproof roller blinds to achieve noise reduction. Similarly, when the noise level detected by noise sensor 3 near the right side panel 104 exceeds the limit, the system controls the opening of n soundproof roller blinds to achieve noise reduction. Likewise, when the noise level detected by noise sensor 3 near the rear panel 105 exceeds the limit, the system controls the opening of n soundproof roller blinds to achieve noise reduction.

[0057] In addition, the system has a self-adjusting function, which can adjust the number of sound insulation curtains 53 around the compressor chamber 102 to be opened according to the actual situation, so as to achieve a better noise reduction effect.

[0058] In addition, the best noise reduction effect can be achieved by adjusting the fan frequency, compressor frequency, and the number (i.e., thickness) of the soundproof curtains 53.

[0059] Specifically, when the noise sensor 3 is adjusted to the fan side via the ring transmission assembly 1 and the linear transmission assembly 2, if the noise level at the fan cavity 101 exceeds the standard, it may be due to an excessively large fan damper or resonance between the fan and the compressor. In this case, the noise can be reduced in the following ways: With a fixed compressor frequency, if the damper is too large but meets the airflow requirements, the system can automatically adjust the damper appropriately to reduce the noise level. With a fixed fan frequency, provided the performance requirements are met, the system can automatically adjust the damper and compressor frequency appropriately to avoid resonance noise, thereby reducing the noise level.

[0060] When the noise sensor 3 is adjusted to the compressor side via the ring transmission assembly 1 and the linear transmission assembly 2, if the noise level at the compressor chamber 102 exceeds the standard, it may be due to resonance between the compressor and the pipeline or a problem with the compressor itself. In this case, the noise can be reduced in the following ways: With the fan speed fixed, if the inverter unit operates at high frequency, the wavelength of high-frequency sound waves is shorter, and thinner sound insulation materials can effectively absorb the sound. Similarly, with the fan speed fixed, if the inverter unit operates at low frequency, the wavelength of low-frequency sound waves is longer, and thicker sound insulation materials can effectively absorb the sound.

[0061] In another optional embodiment, the sound insulation and noise reduction device includes sound-insulating cotton installed on the wall of the press chamber. The installation of the sound-insulating cotton is simpler, requiring no complex transmission components; it can be directly pasted and fixed to the press chamber wall, greatly saving installation time and labor costs. Furthermore, the sound-insulating cotton is available in various materials, allowing for the selection of products with different thicknesses and densities to achieve the best noise reduction effect according to actual needs. Specifically, the system automatically analyzes whether low-frequency or high-frequency sounds are dominant based on test values ​​and takes corresponding measures to reduce noise levels, thereby improving the user experience. High-frequency sounds, due to their longer wavelengths, can be effectively eliminated using thinner sound-insulating cotton; while low-frequency sounds, due to their shorter wavelengths, require thicker sound-insulating cotton for elimination.

[0062] The noise sensor of this invention can be adjusted in position via a guide rail to accurately measure noise levels at different locations. Furthermore, the system automatically determines whether low-frequency or high-frequency sounds are dominant based on the test values, and takes corresponding measures to effectively reduce noise, significantly improving the user experience.
