Description

Technical Field

[0001] The present invention mainly relates to the technical field of energy-saving air conditioners, and particularly relates to a low-noise and silent energy-saving household air conditioner device. Background Art

[0002] An air conditioner, also called an air conditioner regulator, refers to a device that adjusts and controls parameters such as the temperature, humidity, and flow rate of the air in the environment of a building or structure through artificial means. An air conditioner usually consists of structures such as a compressor, a condenser, an evaporator, and a one-way valve capillary tube assembly. When the outdoor unit of the air conditioner is working, it will emit a relatively large noise, and a noise reduction device is usually used to reduce the noise of the outdoor unit of the air conditioner.

[0003] Traditional noise reduction devices include structures such as a sound-absorbing shell, a sound-absorbing member, a positioning plate, a fixing plate, a heat-absorbing plate, a heat-conducting plate, and a sealing member. The advantage of this noise reduction device is that through the setting of structures such as the sound-absorbing shell and the sound-absorbing member, it can play a role in reducing the noise of the outdoor unit of the air conditioner. However, when this noise reduction device is in use, it wraps the outdoor unit of the air conditioner through the mutual cooperation of structures such as the sound-absorbing shell, the sound-absorbing member, and the plate body, resulting in poor ventilation effect of this noise reduction device, which is not conducive to the popularization and use of this noise reduction device. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In the present invention, through the arrangement of the sound insulation felt inside the protective cover, the noise generated by the air conditioner outdoor unit is absorbed. The support bar provides support for the sound insulation board, and the sound insulation board absorbs noise at the ventilation holes.

[0017] When the air conditioner outdoor unit is turned off or the temperature inside the protective cover is relatively low, in the present invention, through the synchronous rotation of multiple sound insulation boards, the ventilation holes are closed, thereby assisting the sound insulation felt to absorb noise.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] The embodiment of the present application provides a noise reduction device for a fixed-frequency air conditioner, including an outdoor unit 1 of the air conditioner. A protective cover 2 is sleeved outside the outdoor unit 1 of the air conditioner, and a noise reduction mechanism 3 is arranged inside the protective cover 2.

[0027] The noise reduction mechanism 3 includes noise collectors 31 connected to multiple top corners inside the protective cover 2, and a ventilation component 32 arranged at one end of the protective cover 2.

[0028] The ventilation component 32 includes a ventilation hole 321 connected to one side of the protective cover 2, a temperature sensor 323 connected to the side of the protective cover 2 close to the ventilation hole 321, and a plurality of sound-absorbing plates 322 connected inside the ventilation hole 321 on one side of the protective cover 2. The plurality of sound-absorbing plates 322 are arranged in sequence from top to bottom.

[0029] Specifically, please refer emphatically to the attached Figure 1 and 2 , sound-absorbing felts 21 are connected to multiple inner wall surfaces of the protective cover 2;

[0030] Support bars 327 are arranged on both sides of the ventilation hole 321. The support bars 327 are connected to the inside of the protective cover 2, and the support bars 327 are rotatably connected to the sound-absorbing plates 322 through rotating shafts.

[0031] The support bar 327 has a hollow structure. Inside the support bar 327, there is a first gear 324 coaxially arranged with the sound insulation board 322. Adjacent first gears 324 are connected by a second gear 325. The second gear 325 is connected to the support bar 327 through a rotating shaft;

[0032] It should be noted that in this embodiment, the protective cover 2 absorbs the noise generated by the air conditioner outdoor unit 1 through the setting of the sound insulation felt 21;

[0033] Furthermore, the support bar 327 provides support for the sound insulation board 322. Through the setting of the rotating shaft, the sound insulation board 322 can rotate;

[0034] Furthermore, since there is a second gear 325 between adjacent first gears 324 and the second gear 325 meshes with the first gear 324, when one of the first gears 324 rotates, multiple first gears 324 rotate synchronously. Since the first gear 324 is coaxially arranged with the sound insulation board 322, the sound insulation board 322 is driven to rotate synchronously, so as to adjust the air outlet direction of the air conditioner outdoor unit 1 through the sound insulation board 322.

[0035] Specifically, please refer to the attached Figure 2 and 3 , on the outer surface of one of the support bars 327, there is a motor 326 connected. The output shaft of the motor 326 is connected to the adjacent first gear 324;

[0036] It should be noted that in this embodiment, the motor 326 drives the first gear 324 connected to its output shaft to rotate.

[0037] Specifically, please refer to the attached Figure 2 and 3 , at the top of the protective cover 2, there is a sound wave generator 22 inserted;

[0038] Inside the protective cover 2, there is a microcontroller 33 connected. The microcontroller 33 is electrically connected to the motor 326, the temperature sensor 323, the noise collector 31, and the sound wave generator 22;

[0039] It should be noted that in this embodiment, the sound wave generator 22 emits sound waves with the same frequency and opposite phase as the identified noise to eliminate the noise of the air conditioner outdoor unit 1;

[0040] Furthermore, the noise collector 31 collects the noise generated by the air conditioner outdoor unit 1, and the microcontroller 33 processes the noise information, so that the microcontroller 33 controls the sound wave generator 22 connected to it to work;

[0041] The temperature sensor 323 with the model number JX90614 measures the internal temperature of the protective cover 2, and the microcontroller 33 connected to the temperature sensor 323 determines whether the temperature exceeds the threshold value.

[0042] The specific operation mode of the present invention is as follows:

[0043] When using the outdoor unit 1 of the air conditioner, through the setting of the sound-absorbing felt 21 in the protective cover 2, the noise generated by the outdoor unit 1 of the air conditioner is absorbed. The support bar 327 provides support for the sound-absorbing plate 322, and the sound-absorbing plate 322 absorbs noise at the ventilation hole 321.

[0044] When the outdoor unit 1 of the air conditioner is turned off or the internal temperature of the protective cover 2 is relatively low, through the synchronous rotation of multiple sound-absorbing plates 322, the ventilation hole 321 is closed, thereby assisting the sound-absorbing felt 21 to absorb noise.

[0045] The above describes the present invention by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
