DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The purpose of the present invention is to provide an air conditioner noise reduction device to solve the problems existing in the prior art and to effectively reduce the vibration and noise of the air conditioner outdoor unit to avoid excessive noise affecting people's daily life.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, this embodiment provides an air-conditioning noise reduction device, including a fixed base 1, a mounting plate 2, a damper 3, a vibration-damping spring 4 and a soundproof cover 5. The mounting plate 2 is mounted on the fixed base 1, and the mounting plate 2 is used to mount an air-conditioning outdoor unit 6. A plurality of dampers 3 are arranged between the mounting plate 2 and the fixed base 1. A vibration-damping spring 4 is sleeved on the outside of each damper 3. Both ends of the vibration-damping spring 4 are respectively connected to the mounting plate 2 and the fixed base 1. The soundproof cover 5 is mounted on the fixed base 1, and is used to cover the air-conditioning outdoor unit 6 inside. An opening is provided on one side of the soundproof cover 5, and a sound-absorbing cotton layer 7 and a porous sound-damping board layer 8 are provided on the inner surface of the soundproof cover 5 in sequence.

[0023] When in use, the air conditioner outdoor unit 6 is fixedly mounted on the mounting plate 2. The damper 3 and the vibration-damping spring 4 are arranged to buffer and reduce vibration of the air conditioner outdoor unit 6, which can effectively reduce noise. The soundproof cover 5, the sound-absorbing cotton layer 7, and the porous soundproof board layer 8 can further reduce noise, thereby effectively reducing vibration and noise of the air conditioner outdoor unit 6 to prevent excessive noise from affecting people's daily lives. The sound waves of each frequency band emitted by the air conditioner outdoor unit 6 first reach the porous soundproof board layer 8, and the sound waves penetrate the porous soundproof board layer 8, enter the sound-absorbing cotton layer 7, and reflect back and forth between the porous soundproof board layer 8 and the soundproof cover 5. When passing through the sound-absorbing cotton layer 7, the sound energy is converted into heat energy through the internal friction of air molecules and the mechanical vibration of fine fibers, thereby achieving the purpose of sound absorption and noise reduction.

[0024] In this embodiment, the mounting plate 2 is a square plate, and clamping plates 9 are slidably connected to the four sides of the mounting plate 2. Each clamping plate 9 slides in a slide groove 11 on the mounting plate 2 through a slider 10 at the bottom thereof. A screw rod 12 is rotatably connected to each slide groove 11, and the screw rod 12 is threadedly connected to the slider 10. The clamping plate 9 is driven to slide along the slide groove 11 by rotating the screw rod 12. By adjusting the position of each clamping plate 9, it can be applied to the installation and clamping of air conditioner outdoor units 6 of different sizes, thereby expanding the scope of application.

[0025] In this embodiment, the slider 10 is a dovetail slider, and the slide groove 11 is a dovetail slide groove that matches the dovetail slider. The dovetail matching structure can prevent the slider 10 from escaping from the slide groove 11 upwards while ensuring the stability of the sliding.

[0026] In this embodiment, an adjusting nut 13 is fixed to one end of each screw rod 12 away from the center of the mounting plate 2. The adjusting nut 13 can be screwed with a wrench to drive the screw rod 12 to rotate, thereby adjusting the position of the clamping plate 9.

[0027] In this embodiment, a plurality of micropores are evenly spaced on the porous sound insulation board layer 8. The diameter of the micropores is 0.5-8 mm, and the micropore spacing is 2-40 mm. When in use, different diameters and spacings can be set according to actual conditions.

[0028] In this embodiment, the soundproof cover 5 is made of sheet metal or polyvinyl chloride board. The sheet metal and polyvinyl chloride board have good sound insulation effect and can reflect sound waves well, so that the sound waves can be repeatedly reflected and absorbed in the sound-absorbing cotton layer 7, thereby reducing noise.

[0029] In this embodiment, the thickness of the porous sound insulation board layer 8 is 2-12 mm, the thickness of the sound absorbing cotton layer 7 is 5-80 mm, and the thickness of the sound insulation cover 5 is 1-3 mm. Different thickness values ​​can be set according to actual use.

[0030] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
