Referring to fig. 1 to 5, fig. 1 is a schematic structural view of an outdoor unit according to an embodiment of the present invention; FIG. 2 is a schematic view of a partial structure of an outdoor unit according to the present invention; fig. 3 is a schematic structural view of an outdoor unit according to another embodiment of the present invention; fig. 4 is a partially enlarged view of a portion a in fig. 3.

In an embodiment of the present invention, the outdoor unit includes a casing 110, a compressor 160, and a wrapping layer 210, wherein the compressor 160 is installed in the casing 110, and the wrapping layer 210 is wrapped on a casing 151 of the compressor 160; the wrapping layer 210 comprises a sound absorption layer, a sound insulation layer and a flame retardant layer; the sound absorption layer and the sound insulation layer sequentially cover the surface of the shell 151, the sound absorption layer is attached to the shell 151, and the flame retardant layer covers the sound absorption layer and/or the sound insulation layer.

Specifically, in this embodiment, the compressor 160 is a hermetic compressor 160, and the compressor 160 includes a housing 151, and an electric component and a compression component disposed inside the housing 151, wherein the electric component is capable of generating a driving force, and the compression component is connected to the electric component and is capable of sucking, compressing, and discharging a fluid. The housing 151 is a cylindrical housing 151, an air outlet is formed at one end of the housing 151, and an air inlet is formed on a side wall of the housing 151. The air inlet and the air outlet are communicated with the outside through a refrigerant pipe after the wrapping layer 210 wraps the shell 151. The case 110 includes a case body, a top cover, a face frame and a bottom plate, and the face frame is provided with an air outlet grille 130. The heat exchanger 120, the wind wheel, the motor, the electric control board, the compressor 160 and other components are arranged in the case 110. The wind wheel is arranged corresponding to the air outlet grille, which is beneficial to increasing the flow of air, so that the heat exchanger 120 can exchange heat with the surrounding air in time.

The wrapping layer 210 wraps the housing 161 in many ways, such as by glue, by silica gel, or by foam, and it should be noted that the wrapping in this embodiment means to bond and fix the wrapping layer 210 and the housing 161.

The sound absorption layer is used to absorb noise generated by vibration of the compressor 160, the sound insulation layer is used to block transmission of the noise, and the flame retardant layer is used to prevent the outdoor unit from catching fire due to high external temperature. The wrapping layer further comprises a waterproof layer, and the waterproof layer is used for preventing water from corroding the shell 151, the sound absorption layer, the sound insulation layer and the flame retardant layer. When the noise generated by the vibration of the compressor 160 is transmitted, the sound absorbing layer absorbs a part of the sound energy, the sound insulating layer blocks the sound transmission, the sound waves are reflected back to the sound absorbing layer, the sound absorbing layer absorbs a part of the sound energy again, the sound waves are reflected again after colliding with the housing 151, and the process is repeated until the energy consumption of the sound waves is completed. In this process, the sound waves penetrating the soundproof layer gradually decrease in energy as they penetrate the flame retardant layer and the waterproof layer, so that the volume of sound passing through the wrapping layer 210 is small.

With regard to the relationship among the flame-retardant layer, the sound-absorbing layer, and the sound-insulating layer, the flame-retardant layer may be parallel to the sound-insulating layer and then covered on the sound-insulating layer, i.e., on the outermost layer, or of course may be covered on the sound-absorbing layer, i.e., between the sound-absorbing layer and the sound-insulating layer. Of course, in some embodiments, the flame retardant layer may also be disposed on top of the sound absorbing layer and the sound insulating layer, i.e., to prevent fire from burning the material of the sound absorbing layer and the sound insulating layer from above.

According to the invention, the wrapping layer 210 is attached to the shell 151, so that the resistance required to be overcome by the compression component of the compressor 160 body driving the shell 151 to vibrate is increased, which is equivalent to increasing the damping of the vibration of the shell 151, and thus the vibration frequency of the compressor 160 can be reduced; when the vibration of the casing 151 is transferred to the soundproof layer and the sound-absorbing layer, the wrapping layer 210 converts the energy of the vibration into one or more of kinetic energy, thermal energy, or potential energy, so that both the sound-absorbing layer and the soundproof layer can absorb and block the vibration of the compressor 160; similarly, the sound absorbing layer and the sound insulating layer can also block and absorb the sound generated by the vibration of the compressor 160, so that the wrapping layer 210 reduces the noise generated by the compressor 160 body from the sound source and the sound itself, thereby effectively reducing the noise generated by the compressor 160 body and being beneficial to reducing the noise pollution; simultaneously, through setting up the puigging in the outside on sound absorbing layer for the sound wave is after sound absorption through sound absorbing layer, is blockked the sound wave that returns by the puigging and is absorbed by sound absorbing layer once more, so, the effectual transmission that reduces the sound wave.

The sound absorption layer and/or the sound insulation layer comprise sound absorption cotton, the sound absorption cotton is provided with a Susong expansion structure (a plurality of gaps are formed inside the sound absorption cotton), vibration generated by the compressor is continuously absorbed by the sound absorption cotton on the periphery of the gaps in the moving process along with the movement of the gaps inside the sound absorption cotton after contacting the sound absorption cotton, and the sound absorption cotton converts the absorbed vibration into heat energy; meanwhile, noise generated by the vibration of the shell of the compressor moves along with the gap inside the sound-absorbing cotton, is continuously absorbed by the sound-absorbing cotton on the periphery of the gap in the moving process, and is converted into heat energy to be dissipated.

Referring to table 1 and fig. 6, data tables and data graphs of the sound absorbing layer and/or the sound insulating layer including sound absorbing cotton are shown, wherein ① represents the noise level of the outdoor unit in the bare state, ② represents the noise level of the outdoor unit in the sound absorbing layer and/or the sound insulating layer including sound absorbing cotton, fig. 6 is a graph comparing outdoor unit noise curves corresponding to table 1.

On the basis of the above embodiment, the sound insulation layer and/or the sound absorption layer further comprises a rubber layer, and the rubber layer covers the sound absorption cotton.

In this embodiment, the rubber layer can be the rubber skin, and the rubber layer is with the compressor body with inhale the cotton parcel in wherein, when the produced vibration of casing after passing and inhaling the sound cotton, partial vibration is absorbed by the rubber layer, and the part is reflected back by the rubber layer and is inhaled the sound cotton, inhales the sound cotton and carries out energy conversion again to the partial vibration of being reflected and handle, if also the vibration pierces through and inhale the sound cotton transmission to the casing on, the casing with partial vibration rebound again to inhaling the sound cotton, so relapse until the energy of vibration is whole to be converted into heat energy. Similarly, the noise generated by the housing and the compression assembly after penetrating through the sound-absorbing cotton meets the rubber layer, is partially absorbed by the rubber layer, and is partially reflected back to the rubber layer until the sound-absorbing cotton converts the noise energy into heat energy.

Further, on the basis of the above-described embodiment, referring to fig. 4 and 5, fig. 5 is a partially enlarged view at B in fig. 4. The sound-insulating layer and/or the sound-absorbing layer comprise an elastic powder 211 and/or elastic particles.

Specifically, in this embodiment, the sound insulation layer and the sound absorption layer can be elastic particles, elastic powder 211 or a mixture of elastic particles and elastic powder 211, and of course, in some embodiments, the sound insulation layer and the sound absorption layer can be mixed into one layer, which can be referred to as a noise reduction layer, that is, the noise reduction layer has both the function of sound absorption and the function of sound insulation. The resilient particles may include one or more of perlite particles, vermiculite particles, rubber particles and silica gel particles. The elastic powder 211 may include one or more of perlite powder, vermiculite powder, rubber powder, and silica gel powder. Whether there are gaps between particles or powder particles, when sound passes through a particle layer or a powder layer, sound waves bypass the particles or powder and propagate in a channel formed by the connection of the gaps, energy of the sound waves is absorbed by the powder or particles during propagation, and the powder or particles convert the energy of the sound waves into one or more of potential energy, kinetic energy or thermal energy. Because the quantity of the particles and the powder is large, the formed sound wave has more passages capable of being transmitted, so that the sound wave is fully contacted with the particles, the attenuation efficiency of sound wave energy is favorably increased, and the transmission of noise is effectively reduced. Mutual extrusion and deformation exist between the elastic particles and the elastic powder 211, so that the elastic particles and the powder are extruded and attached to the shell 151, and the elastic powder 211 and the particles are tightly attached to the shell 151, when the shell 151 is driven to vibrate by an electric structure assembly and a compression structure assembly in the shell 151, the resistance required to be overcome by driving the shell 151 to vibrate is increased, the damping of the vibration of the shell 151 is increased, and the vibration frequency of the compressor 160 can be reduced; meanwhile, the vibration of the housing 151 is transmitted out through the elastic particles and the powder in contact therewith, and the vibration drives the particles and the powder to vibrate in the transmission process between the particles or between the powders, so that the particles and the powder are deformed, friction occurs between the particles and between the powders, and even the particles and the powder are displaced, thereby enabling the energy of the vibration to be converted into kinetic energy, potential energy (including elastic potential energy) and thermal energy, thereby effectively attenuating the energy of the vibration, and further reducing noise generated due to the vibration transmission.

Referring to table 2 and fig. 7, data tables and data graphs of the sound absorbing layer and/or the sound insulating layer including rubber powder indicate that ① indicates the magnitude of noise of the outdoor unit in a bare state, ② indicates the magnitude of noise of the outdoor unit in a sound absorbing layer and/or the sound insulating layer including rubber powder, and fig. 7 is a graph comparing noise curves of the outdoor unit corresponding to table 2.

The foaming material may be combined with the elastic powder 211, or may be combined with the elastic particles. The foaming material, the elastic particles and the elastic powder 211 may be separately provided. Or the mixture may be mixed, that is, in the foaming process of the foam material, a proper amount of the elastic powder 211 and the elastic particles are added to the foam material, so that the foam material contains the elastic powder 211 and the elastic particles, and the formed foam material has both the sound absorption function and the sound insulation function.

The foaming material in the embodiment is a high molecular polymer which is prepared by mixing isocyanate and polyether serving as main raw materials through special equipment under the action of various auxiliary agents such as a foaming agent, a catalyst, a flame retardant and the like and foaming on site through high-pressure spraying. The polyurethane has two types of soft bubbles and hard bubbles, and the soft bubbles are soft bubbles in the embodiment and have open pore structures.
