Description
Technical Field
The utility model belongs to the technical field of the air conditioning technology and specifically relates to an air condensing units casing and air conditioner is related to.
Background
The existing outdoor unit of air conditioner is equipped with compressor and piping system, and the compressor and piping system can produce vibrations, and noise when working. Although sound insulation materials are arranged at the compressor and the piping system in the market, the sound insulation effect is not good, and the user experience is still affected by vibration and noise generated by the compressor and the piping system during operation.
Patent document CN106556081A discloses an outdoor unit casing of an air conditioner and an outdoor unit of the air conditioner, wherein a first sound insulation layer, a second sound insulation layer and a shockproof layer are additionally arranged on the inner side of the outdoor unit casing of the air conditioner to realize the mute operation of the outdoor unit of the air conditioner, so as to prevent the outdoor unit of the air conditioner from generating noise and vibration during operation to influence the user experience. Because this patent relates to and pastes three-layer combined material to whole air conditioner outer casing, not only the material increases and leads to the cost to rise, and outer casing area is big moreover, and the technical worker operation degree of difficulty is high, and man-hour consumption is more. Meanwhile, the noise of a fan room and a compressor cabin cannot be effectively separated, the compressor is ignored to be the main noise source of the air conditioner outdoor unit, and the beat vibration problem cannot be effectively solved.
Disclosure of Invention
The utility model discloses a first purpose provides an air conditioner outdoor unit casing that can reduce air conditioner noise, beat the sound of shaking simultaneously and weaken.
A second object of the present invention is to provide an air conditioner with the above air conditioner outdoor unit casing.

It can be seen from the above scheme that, by designing the middle partition plate into a multi-layer structure including the first support plate, the first sound insulation layer, the second sound insulation layer, the first sound absorption layer and the second sound absorption layer, the vibration noise generated by the operation of the fan is absorbed by the first sound absorption layer and separated by the first sound insulation layer, and the vibration noise generated by the compressor is absorbed by the second sound absorption layer and separated by the second sound insulation layer. Because the beat vibration of the outdoor unit of the air conditioner is caused by the fact that the frequency of the rotating noise of the axial flow fan is close to the running frequency of the rotor compressor and the two sound frequencies are subjected to cross interference, the middle partition plate of the multilayer structure effectively weakens the energy generated by the interference of the two sound frequencies by separating the two vibration sources, so that the noise and vibration transmission of the compressor cabin and the fan room are effectively separated, and the beat vibration sound of the air conditioner is weakened.
Simultaneously, according to simulation result and measured data show, as long as all design into the multilayer structure including second backup pad, third puigging and third sound absorbing layer with left side board and posterior lateral plate, can reach fine noise reduction effect, whether carry out sound absorption noise reduction treatment to preceding curb plate and top cap and influence little to noise reduction effect, and the outside surface of second backup pad is the outward appearance face, need not to set up puigging and sound absorbing layer, can reach fine noise reduction effect, user experience is improved, and the cost is also reduced simultaneously.
Preferably, the first soundproof layer, the second soundproof layer, and the third soundproof layer are made of rubber.
In a further embodiment, the rubber is chlorinated butyl rubber or butyl rubber.
It can be seen that, while chlorinated butyl rubber has a better sound-insulating effect on low-frequency noise than butyl rubber, butyl rubber has a better sound-insulating effect on high-frequency noise than chlorinated butyl rubber. According to the actually measured noise data of the outdoor unit of the air conditioner, chlorinated butyl rubber is selected when low-frequency noise is large, and butyl rubber is selected when high-frequency noise of a compressor is large.
Preferably, the first sound-absorbing layer, the second sound-absorbing layer and the third sound-absorbing layer are made of porous materials.
Further, the porous material is a knitted fiber or felt.
Therefore, the knitted fiber and the felt both have good sound absorption effect, the felt can be green felt fiber or green felt, and the sound absorption of the knitted fiber is better than that of the green felt fiber.
In a preferred embodiment, the first support plate and the second support plate are both galvanized plates.
Preferably, the air conditioner outdoor unit casing further includes a top cover located on the top of the compressor compartment, and at least one of the front panel and the top cover is a single-layer wall panel.
The further proposal is that the single-layer wallboard is a galvanized plate.
Therefore, according to simulation results and actual measurement data, the good noise reduction effect can be achieved as long as the left side plate and the rear side plate are subjected to noise reduction treatment, whether the noise absorption and noise reduction treatment is carried out on the front side plate and the top cover is small in influence on the noise reduction effect, and the front side plate and the top cover directly adopt the use of the galvanized sheet reducible material, so that the cost is reduced.
Preferably, the air conditioner outdoor unit casing further comprises a top cover located on the top of the compressor compartment, and the front side plate and the top cover are both multilayer wall plates.
Therefore, the sound absorption and noise reduction treatment is carried out on the front side plate and the top cover, so that the noise reduction effect can be further improved.
In order to achieve the second objective, the utility model provides an air conditioner includes compressor, fan and foretell air condensing units casing, and the compressor is installed in the compressor cabin, and the fan is installed in the fan room.
