Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning equipment, and in particular to an air-conditioning ventilation noise reduction device for reducing noise. Background Art

[0002] The air conditioner is composed of an air conditioner main unit and an air conditioner outdoor unit. As you can imagine, the air conditioner outdoor unit is installed outdoors. When the air conditioner is started, the motor inside the air conditioner outdoor unit drives the fan blades to rotate to dissipate heat from the condenser. The fan blades will vibrate during the rotation, and the noise generated by the operation of the air conditioner is mainly caused by the wind sound when the fan is running and the friction or poor lubrication between the fan and the rotor. The noise generated by the air conditioner has a certain impact on the daily life of the residents, and in specific applications, the inside of the air conditioner outdoor unit also needs to be dust-proofed.

[0003] For example, Chinese patent CN219222806U discloses an air conditioning ventilation noise reduction structure, including: a noise reduction frame, the inner wall of the noise reduction frame is provided with ventilation grooves, a limit plate, the limit plate is arranged on the outer wall of the noise reduction frame, the inner wall of the limit plate has two sets of limit grooves, the inner wall of the limit groove is movably provided with a push rod, and the outer wall of the push rod is provided with a protective plate. It can prevent a large amount of dust, large particles or insects from being adsorbed on the fan blades of the air conditioner host. However, when the above-mentioned ventilation noise reduction structure is used for dust protection, the user needs to manually pull the L-shaped bracket to drive the protective plate for protection. This operation is relatively cumbersome and cannot be used for protection according to the start and shutdown of the air conditioner, thereby reducing the convenience of user experience.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0032] With the help of the above-mentioned technical scheme of the utility model, the structure of the utility model is reasonable, scientific and novel. It can not only effectively reduce the noise generated when the air conditioner is running, achieve noise reduction, and improve the efficiency and comfort of the air-conditioning system, but also automatically protect the air-conditioning outdoor unit. At the same time, the function of shock absorption is realized under the coordinated use of the spring 4 and the rubber plate 401, thereby improving the versatility of the air-conditioning ventilation noise reduction device.

[0033] In one embodiment, for the above-mentioned protective mechanism 7, the protective mechanism 7 includes a mounting seat 701 arranged on the inner wall of the shell 1, and the cross-section of the mounting seat 701 is circular, a circular ring 702 is arranged on the inner and outer sides of the mounting seat 701, and a plurality of protective plates 703 are arranged in the middle of the mounting seat 701, and a mounting shaft 704 connected to the inner wall of the mounting seat 701 is penetrated at one end of the protective plate 703, and a connecting rod 705 connected to one side of the circular ring 702 is arranged at the other end of the protective plate 703; an electric telescopic rod 706 connected to the inner wall of the shell 1 is arranged on the outer side of the mounting seat 701, a ventilation hole 7011 is opened in the middle of the mounting seat 701, and a plurality of limit columns 7012 are arranged on the outer side of the inner wall of the mounting seat 701. A through hole 7013 is provided on the outer side of 701; a plurality of limiting holes 7021 matching with the limiting column 7012 are provided on the side wall of the ring 702, and an extension rod 7022 penetrating the through hole 7013 is provided on the outer side of the ring 702, and one end of the extension rod 7022 is connected to one end of the piston rod of the electric telescopic rod 706 through a universal joint; a plurality of protective plates 703 are arranged in a ring shape, and a circular structure is formed between the plurality of protective plates 703, thereby realizing the protection of the air conditioner outdoor unit.

[0034] The working principle of the protection mechanism 7 is as follows: the piston rod of the electric telescopic rod 706 is extended or shortened, and the extension rod 7022 is driven to move under the action of the universal joint, thereby driving the ring 702 to rotate, and then the connecting rod 705 is rotated to drive the protection plate 703 to rotate around the installation shaft 704, so that several protection plates 703 can be opened or closed, so that the air conditioner can be protected when it is not in use, and the ventilation of the air conditioner outdoor unit can be achieved when it is in use.

[0035] In one embodiment, for the above-mentioned noise reduction mechanism 8, the noise reduction mechanism 8 includes a frame 801 arranged on the inner wall of the shell 1, and sound-absorbing panels 802 are symmetrically arranged inside the frame 801, and sound-absorbing cotton 803 is arranged between the sound-absorbing panels 802, thereby achieving noise reduction of the air conditioner. The sound-absorbing panels 802 can effectively absorb and reduce the noise generated by the air-conditioning outdoor unit, and placing sound-absorbing cotton 803 between the sound-absorbing panels 802 can further improve the overall sound absorption efficiency, thereby improving the overall performance and user experience of the air-conditioning equipment.

[0036] It should be noted that the sound-absorbing panel 802 is made of porous or fibrous materials. The main function of the sound-absorbing panel 802 is to absorb sound waves passing through it, reduce sound reflection and echo, and help reduce the noise generated when the air-conditioning system is running; the sound-absorbing cotton 803 is made of soft fiber materials, such as glass fiber, rock wool or high-density polyester fiber. The sound-absorbing cotton 803 is placed between the sound-absorbing panels 802 as a filling material, which can further absorb and block the propagation of sound waves.

[0037] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0038] In actual application, the air-conditioning outdoor unit is placed on the air-conditioning mounting plate 5 and installed through the air-conditioning mounting hole 6, and then the shell 1 can be installed at the installation position. When the air-conditioning outdoor unit is in use, ventilation can be carried out by opening the protective mechanism 7, and then the noise generated by the air-conditioning outdoor unit is weakened by the noise reduction mechanism 8. At the same time, when the air-conditioning outdoor unit is running, the vibration generated is first transmitted to the spring 4 through one of the rubber plates 401, and then transmitted to the other rubber plate 401. The rubber plate 401 and the spring 4 can slow down the propagation of the vibration through their vibration absorption characteristics, thereby effectively reducing the impact of the vibration generated by the air-conditioning outdoor unit on the surrounding environment. When the air conditioner is not in use, the protective mechanism 7 can be closed to protect the air-conditioning outdoor unit.

[0039] In summary, with the help of the above-mentioned technical scheme of the utility model, the structure of the utility model is reasonable, scientific and novel. It can not only effectively reduce the noise generated when the air conditioner is running, achieve noise reduction, and improve the efficiency and comfort of the air-conditioning system, but also automatically protect the air-conditioning outdoor unit. At the same time, the spring 4 and the rubber plate 401 are used in conjunction to achieve the function of shock filtering, thereby improving the versatility of the air-conditioning ventilation and noise reduction device; by setting the protection mechanism 7, the protection of the air-conditioning outdoor unit is achieved. When the air conditioner is not in use, the protection plate 703 can be driven to move by the electric telescopic rod 706, thereby protecting the air-conditioning outdoor unit, avoiding damage to the air-conditioning outdoor unit caused by dust, debris or external factors, and improving the service life of the air conditioner; by setting the noise reduction mechanism 8, the noise reduction of the air conditioner is achieved. The sound absorbing panel 802 can effectively absorb and reduce the noise generated by the air-conditioning outdoor unit. Placing sound absorbing cotton 803 between the sound absorbing panels 802 can further improve the overall sound absorption efficiency, thereby improving the overall performance and user experience of the air-conditioning equipment.
