Description

Technical Field

[0001] This utility model relates to the field of central air conditioning technology, and in particular to an energy-saving central air conditioning noise reduction retrofit device. Background Technology

[0002] Currently, during operation, energy-saving central air conditioning systems often generate significant noise from their outdoor units due to compressor vibration, fan operation, and component resonance. This noise not only affects the comfort of the surrounding environment but may also have a certain impact on human health. Existing noise reduction devices for central air conditioning outdoor units often have many shortcomings: some devices only use a single sound insulation structure, which is insufficient to comprehensively block various types of noise, especially low-frequency noise generated by vibration transmission and high-frequency noise generated by the operation of heat dissipation equipment, resulting in poor noise reduction effects; at the same time, in pursuit of sound insulation effects, some devices are sealed too tightly, leading to poor heat dissipation of the outdoor unit, affecting the normal operating efficiency and service life of the air conditioner. Furthermore, when subsequent maintenance of the air conditioner outdoor unit is required, the disassembly process of the device is complicated, significantly reducing maintenance efficiency and causing many inconveniences for users. Therefore, we are introducing a new energy-saving central air conditioning noise reduction retrofit device. Utility Model Content

[0003] The main purpose of this utility model is to provide an energy-saving central air conditioning noise reduction retrofit device, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An energy-saving central air conditioning noise reduction retrofit device includes an installation platform. A U-shaped soundproof shell is detachably installed on the upper center of the installation platform via bolts. A first soundproof cover is provided on the upper center of the U-shaped soundproof shell. A cooling fan is fixedly installed inside the first soundproof cover via an installation bracket. Two sliding grooves are provided on the left and right front ends of the U-shaped soundproof shell. Noise reduction components are provided inside the four sliding grooves. A vibration damping pad is provided on the lower inner wall of the U-shaped soundproof shell. Vibration dampers are provided at the four corners of the lower inner wall of the U-shaped soundproof shell. A fixing plate is provided on the upper end of the four vibration dampers and vibration damping pads. An air conditioner outdoor unit is provided on the upper center of the fixing plate. Vertical plates are provided on the upper left and upper right center of the fixing plate. Rotating screws are threaded onto the opposite sides of the two vertical plates. Clamping plates are movably installed on the opposite faces of the two rotating screws via movable sleeves. Protective pads are provided on the opposite faces of the two clamping plates.

[0006] Preferably, the noise reduction component includes two sound-insulating side panels. Sliding blocks are provided on the upper and lower parts of the facing surfaces of the two sound-insulating side panels. Positioning posts are provided on the upper and lower front ends of the two sound-insulating side panels. A slot is provided in the middle of the front end of each of the two sound-insulating side panels. A positioning groove is provided on the upper inner wall of each of the two slots. A locking hole is provided on the inner wall of each of the two slots. A noise reduction and heat dissipation component is detachably installed inside both slots and the positioning grooves.

[0007] Preferably, both soundproof side panels are slidably installed inside the sliding grooves at the front left and rear left of the U-shaped soundproof shell via sliding blocks.

[0008] By adopting the above technical solution, the sliding structure facilitates quick positioning of the side plate during installation and also facilitates subsequent disassembly.

[0009] Preferably, the two protective pads are tightly fitted to the left and right ends of the outdoor unit of the air conditioner, respectively.

[0010] By adopting the above technical solution, it is convenient to fix the outdoor unit of the air conditioner.

[0011] Preferably, the noise reduction and heat dissipation assembly includes a soundproof door panel. Two second soundproof covers are fixedly installed on the upper and lower front ends of the soundproof door panel via ventilation openings. Exhaust fans are fixedly installed on the inner surfaces of the two second soundproof covers via mounting brackets. Insert blocks are provided on the middle left and middle right rear ends of the soundproof door panel. Positioning blocks are provided at the upper ends of the two insert blocks. Springs are fixedly installed inside the two insert blocks via inner grooves. Guide plates are movably installed inside the two insert blocks via inner grooves. A locking block is fixedly installed at the end of each guide plate away from the spring. Positioning holes are provided at the four rear corners of the soundproof door panel.

[0012] By adopting the above technical solution: the soundproof door panel itself has sound insulation capability, and with the second soundproof cover, it can reduce the airflow noise when the exhaust fan is running. At the same time, the exhaust fan accelerates the air circulation inside the shell, solving the problem of "poor heat dissipation" of traditional soundproof shells. The insert, spring, guide plate and clip form an elastic snap-fit ​​mechanism, which, together with the positioning hole, allows the door panel to be quickly installed and fixed, and is also easy to disassemble and maintain later.

[0013] Preferably, the soundproof door panel is movably connected to the front end of the soundproof side panel through positioning holes and positioning posts.

[0014] By adopting the above technical solution, the precise positioning of the door panel and the soundproof side panel can be achieved by using the cooperation of the positioning hole and the positioning post.

[0015] Preferably, the soundproof door panel is movably engaged inside the slot and positioning groove by means of insert blocks and positioning blocks, and the locking blocks are movably engaged inside the locking holes by means of springs and guide plates.

[0016] By adopting the above technical solution: the insertion block and the slot cooperate to achieve the horizontal positioning of the door panel, and the positioning block and the positioning groove cooperate to achieve the vertical positioning, ensuring the tight fit between the door panel and the sound insulation shell body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a U-shaped soundproof shell to form a surrounding soundproof enclosure for the outdoor unit of the air conditioner, and in conjunction with soundproof side panels and soundproof protective door panels, noise is further blocked from the side and front. The first and second soundproof covers reduce the noise generated by the operation of the cooling fan and exhaust fan, respectively. At the same time, protective pads, shock absorbers, and vibration damping pads reduce vibration transmission to reduce vibration noise. The multiple soundproofing structures effectively block various noises from the outdoor unit of the air conditioner. The cooling fan and exhaust fan work together to accelerate the air circulation inside the shell, ensuring that the outdoor unit of the air conditioner can dissipate heat in a timely manner while achieving efficient soundproofing, thus ensuring its normal operation.

[0019] 2. The soundproof side panel slides within the sliding groove via a sliding block, facilitating quick and easy alignment during installation. The soundproof door panel is quickly fixed by inserting blocks, positioning blocks, slots, and positioning grooves, aided by springs, guide plates, and locking blocks. The positioning holes and positioning posts ensure precise installation. For subsequent maintenance, simply press the locking block to remove the soundproof door panel, and slide the soundproof side panel to open the U-shaped soundproof shell. This simple operation significantly improves the efficiency of installation and maintenance. Attached Figure Description

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] An energy-saving central air conditioning noise reduction retrofit device includes a mounting platform 1. A U-shaped sound insulation shell 2 is detachably mounted on the upper center of the mounting platform 1 via bolts. A first sound insulation cover 3 is provided on the upper center of the U-shaped sound insulation shell 2. A cooling fan 4 is fixedly mounted inside the first sound insulation cover 3 via a mounting bracket. Two sliding grooves 5 are provided on the left and right front ends of the U-shaped sound insulation shell 2. Noise reduction components 6 are provided inside the four sliding grooves 5. A shock-absorbing pad 7 is provided in the middle of the lower inner wall of the U-shaped sound insulation shell 2. Shock absorbers 8 are provided at the four corners of the inner lower wall of the soundproof shell 2. The upper ends of the four shock absorbers 8 and the shock-absorbing pads 7 are all provided with a fixing plate 9. An air conditioner outdoor unit 10 is provided at the upper middle part of the fixing plate 9. Vertical plates 11 are provided at the upper left middle part and the upper right middle part of the fixing plate 9. Rotating screws 12 are threaded through the opposite sides of the two vertical plates 11. Clamping plates 13 are movably installed on the opposite surfaces of the two rotating screws 12 through movable sleeves. Protective pads 14 are provided on the opposite surfaces of the two clamping plates 13.

[0030] In this embodiment, the noise reduction component 6 includes two sound-insulating side plates 61. Sliding blocks 62 are provided on the upper and lower parts of the facing surfaces of the two sound-insulating side plates 61. Positioning posts 63 are provided on the upper and lower front ends of the two sound-insulating side plates 61. Slots 64 are provided in the middle of the front ends of the two sound-insulating side plates 61. Positioning grooves 65 are provided on the upper inner walls of the two slots 64. Card holes 66 are provided on the inner walls of the two slots 64. Noise reduction and heat dissipation components 67 are detachably installed inside the two slots 64 and the positioning grooves 65. The two sound-insulating side plates 61 are slidably installed inside the sliding grooves 5 on the left front end and the left rear end of the U-shaped soundproof shell 2 via the sliding blocks 62. Two protective pads 14 are tightly fitted to the left and right ends of the outdoor unit 10 of the air conditioner, respectively.

[0031] With the above solution: In use, the two soundproof side plates 61 in the noise reduction component 6 slide in the sliding grooves 5 at the front left and rear left of the U-shaped soundproof shell 2 by means of the sliding blocks 62 at the upper and lower parts of the opposite surface, thereby adjusting the spacing to adapt to air conditioner outdoor units 10 of different widths. The positioning posts 63 at the front end of the two soundproof side plates 61 are used to cooperate with the positioning holes 679 of the noise reduction and heat dissipation component 67. The slots 64, positioning grooves 65 and card holes 66 are respectively connected to the insert block 674, positioning block 675 and card block 678.

[0032] In this embodiment, the noise reduction and heat dissipation assembly 67 includes a soundproof door panel 671. Two second soundproof covers 672 are fixedly installed on the upper and lower front ends of the soundproof door panel 671 via ventilation openings. Exhaust fans 673 are fixedly installed on the inner surfaces of the two second soundproof covers 672 via mounting brackets. Insert blocks 674 are provided on the middle left and middle right rear ends of the soundproof door panel 671. Positioning blocks 675 are provided at the upper ends of the two insert blocks 674. Springs 676 are fixedly installed inside the two insert blocks 674 via inner grooves. Each part is equipped with a guide plate 677 that is movably installed through an inner groove. Each of the two guide plates 677 has a locking block 678 fixedly installed at the end away from the spring 676. The four corners of the rear end of the soundproof door panel 671 are provided with positioning holes 679. The soundproof door panel 671 is movably engaged with the front end of the soundproof side panel 61 through the positioning holes 679 and the positioning post 63. The soundproof door panel 671 is movably engaged in the slot 64 and the positioning groove 65 through the insert block 674 and the positioning block 675. The locking block 678 is movably engaged in the slot 66 through the spring 676 and the guide plate 677.

[0033] Through the above scheme: the soundproof door panel 671 of the noise reduction and heat dissipation component 67 is inserted into the slot 64 and positioning groove 65 of the soundproof side panel 61 through the insert block 674 and positioning block 675 at the rear end. At the same time, the spring 676 in the insert block 674 pushes the guide plate 677 to make the locking block 678 lock into the locking hole 66 for fixation. The soundproof door panel 671 is further ensured to be installed accurately and stably through the cooperation of the positioning hole 679 and the positioning post 63. The exhaust fan 673 in the second soundproof cover 672 at the front end is ventilated and dissipated through the ventilation port. At the same time, the second soundproof cover 672 can reduce the noise generated by the operation of the exhaust fan 673, thereby effectively improving the overall sound insulation effect while ensuring heat dissipation.

[0034] It should be noted that this utility model is an energy-saving central air conditioning noise reduction retrofit device. During use, the outdoor unit 10 of the air conditioner is first placed on the upper end of the fixing plate 9 on the mounting platform 1. By rotating the rotating screw 12 on the vertical plate 11, the clamping plate 13 is moved, so that the two protective pads 14 are tightly attached to the left and right ends of the outdoor unit 10, thereby fixing the outdoor unit 10. At the same time, the protective pads 14 can buffer the vibration of the outdoor unit 10 during operation and reduce the transmission of vibration noise. The four shock absorbers 8 and the shock-absorbing pads 7 at the lower end of the fixing plate 9 can further absorb the noise from the outdoor unit. The vibration of the outdoor unit 10 is prevented from being transmitted through the mounting platform 1, thus avoiding noise. The U-shaped soundproof shell 2 is bolted to the mounting platform 1, forming a surrounding soundproof enclosure for the outdoor unit 10. The cooling fan 4 inside the first soundproof cover 3 at its upper end can accelerate the air circulation inside the shell, and the exhaust fan 673 of the noise reduction heat dissipation component 67 enhances the heat dissipation effect. The first soundproof cover 3 can also reduce the noise of the cooling fan 4. The two soundproof side plates 61 of the noise reduction component 6 slide in the sliding groove 5 of the U-shaped soundproof shell 2 through the sliding block 62, which facilitates quick and easy alignment and installation, and makes it tightly wrap around the air conditioner. On both sides of the outdoor unit 10, the sound insulation effect is enhanced. The soundproof protective door panel 671 of the noise reduction and heat dissipation component 67 is fixed by the cooperation of the insert block 674, the positioning block 675 and the slot 64 and positioning groove 65 of the soundproof side panel 61. The spring 676 pushes the guide plate 677 to make the locking block 678 lock into the locking hole 66. At the same time, the positioning hole 679 cooperates with the positioning post 63 to ensure accurate installation. The soundproof protective door panel 671 plays a role in frontal sound insulation, and the second soundproof cover 672 reduces the operating noise of the exhaust fan 673. When subsequent maintenance is required, simply press the card. Block 678 disengages it from the slot 66, allowing the soundproof door panel 671 to be pulled out from the slot 64 and positioning groove 65 of the soundproof side panel 61. Simultaneously, the soundproof side panel 61 can be slid along the sliding groove 5 to open the front and side of the U-shaped soundproof shell 2, facilitating the maintenance of the air conditioner outdoor unit 10. After maintenance, the installation and reset can be performed in reverse order. The entire process effectively blocks the noise of the air conditioner outdoor unit 10 through the multiple soundproof structures of the U-shaped soundproof shell 2, the soundproof side panel 61, the soundproof door panel 671, the first soundproof cover 3, and the second soundproof cover 672.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
