It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

The compressor assembly proposed by the present invention includes a compressor 160 and a wrapping layer, and the wrapping layer wraps the casing 151 of the compressor 160 . The wrapping layer includes a sound absorbing layer and a sound insulating layer. The sound absorbing layer and the sound insulating layer sequentially cover the surface of the casing 151 , and the sound absorbing layer is attached to the casing 151 .

The outdoor unit is well known to everyone. In order for the reader to understand the solution more conveniently, in the following embodiment, the application of the compressor assembly in the outdoor unit is taken as a specific embodiment to describe the solution in detail. It should be understood that the compressor assembly can not only be used in an outdoor unit, but also in a mobile air conditioner, that is, an integrated unit.

The present invention provides an outdoor unit. The present invention mainly adopts the following solutions to reduce vibration and noise of the compressor 160 of the indoor unit. First, a sound-absorbing layer and a sound-insulating layer are arranged on the surface of the casing 151 of the compressor 160, so that the air transmitted from the casing 151 of the compressor 160 is transmitted. Vibration and noise due to vibration are greatly weakened; among them, the materials of the sound-absorbing layer and the sound-insulating layer have been obtained through many designs and repeated experiments, which have significant vibration and noise reduction effects, which will be described in the following examples. The working principle is described in detail; in addition, a mounting post extending upward from the bottom plate of the outdoor unit is provided, and only the bottom of the mounting post is in contact with the bottom plate, and then the compressor 160 is suspended on the mounting post so that the casing 151 of the compressor 160 is suspended, so that the compressor 160 is suspended in the air. The vibration generated by 160 needs to be transmitted through the installation column; the installation column is set to be made of vibration damping material, so that the vibration energy of the compressor 160 is reduced to the greatest extent when passing through the installation column; at the same time, the sound absorption layer and/or sound insulation The flame retardant layer is arranged on the layer, so that the sound-absorbing material and the sound-insulating material are not easily ignited by the outside world, which is beneficial to eliminate the potential safety hazard of burning the sound-absorbing material and the sound-insulating material, and makes the work of the wrapping layer 210 more stable and reliable.

1 to 5, FIG. 1 is a schematic structural diagram of an embodiment of an outdoor unit of the present invention; FIG. 2 is a partial structural schematic diagram of an outdoor unit of the present invention; FIG. 3 is a structural schematic diagram of another embodiment of the outdoor unit of the present invention; It is a partial enlarged view at A in Figure 3.

In the embodiment of the present invention, the outdoor unit includes a casing 110 , a compressor 160 and a wrapping layer 210 , the compressor 160 is installed in the casing 110 , and the wrapping layer 210 wraps the casing of the compressor 160 151; the wrapping layer 210 includes a sound absorbing layer, a sound insulating layer and a flame retardant layer; the sound absorbing layer and the sound insulating layer are sequentially covered on the surface of the casing 151, and the sound absorbing layer is attached to the casing 151, The flame retardant layer covers the sound absorbing layer and/or the sound insulating layer.

Specifically, in this embodiment, the compressor 160 is a hermetic compressor 160, and the compressor 160 includes a casing 151, and an electric structural assembly and a compression structural assembly disposed inside the casing 151, wherein the electric structural assembly can generate The driving force, the compression structure assembly is connected to the above-mentioned electric structure assembly, and the fluid can be sucked, compressed and discharged. The casing 151 is a cylindrical casing 151 , an air outlet is formed at one end of the casing 151 , and an air inlet is formed on the side wall of the casing 151 . After the wrapping layer 210 wraps the casing 151, the air inlet and the air outlet are communicated with the outside through a refrigerant pipe. The chassis 110 includes a box body, a top cover, a face frame and a bottom plate, and the face frame is provided with an air outlet grille 130 . The casing 110 is provided with components such as a heat exchanger 120 , a wind wheel, a motor, an electric control board, and a compressor 160 . Wherein, the arrangement of the wind wheel corresponding to the air outlet grill is beneficial to increase the flow of the gas, so that the heat exchanger 120 can exchange heat with the surrounding air in time.

There are many ways for the wrapping layer 210 to wrap the casing 161 , such as through glue, silica gel, or foamed material.

The sound absorbing layer is used to absorb the noise generated by the compressor 160 due to vibration, the sound insulation layer is used to block the transmission of the noise, and the flame retardant layer is used to prevent the outdoor unit from catching fire due to the high temperature outside. The wrapping layer further includes a waterproof layer, which is used to prevent water from eroding the shell 151 , the sound-absorbing layer, the sound-insulating layer, and the flame-retardant layer. When the noise generated by the vibration of the compressor 160 is transmitted, the sound absorbing layer absorbs part of the sound energy, the sound insulating layer blocks the transmission of the sound, bounces the sound waves back to the sound absorbing layer, and the sound absorbing layer absorbs part of the sound energy again. After the collision, it bounces again, and so on until the energy of the sound wave is exhausted. During this process, the energy of the sound wave penetrating the soundproof layer gradually decreases as it penetrates the flame retardant layer and the waterproof layer, so that the sound wave passing through the wrapping layer 210 is small.

Among them, regarding the relationship between the flame-retardant layer, the sound-absorbing layer and the sound-insulating layer, the flame-retardant layer can be parallel to the sound-insulating layer, and then covered on the sound-insulating layer, that is, the outermost layer, and of course, can also be covered on the sound-absorbing layer, that is It is arranged between the sound-absorbing layer and the sound-insulating layer. Of course, in some embodiments, the flame retardant layer can also be provided on the upper part of the sound absorbing layer and the sound insulating layer, that is, to prevent fire from burning the materials of the sound absorbing layer and the sound insulating layer from the upper part.

In the present invention, by attaching the wrapping layer 210 to the casing 151, the resistance that the compression assembly of the compressor 160 body needs to overcome to drive the casing 151 to generate vibration increases, which is equivalent to increasing the vibration damping of the casing 151, which can reduce the The frequency of the vibration of the small compressor 160; when the vibration of the casing 151 is transmitted to the sound insulation layer and the sound absorption layer, the wrapping layer 210 converts the vibration energy into one or more of kinetic energy, thermal energy or potential energy, so that the sound absorption layer and the sound insulation layer Both can absorb and block the vibration of the compressor 160 at the same time; 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 at the same time, so that the wrapping layer 210 reduces the body of the compressor 160 from the sound source and the sound itself. The generated noise effectively reduces the noise generated by the body of the compressor 160, which is conducive to reducing noise pollution; at the same time, by disposing the sound insulation layer on the outside of the sound absorption layer, the sound waves are blocked by the sound insulation layer after passing through the sound absorption layer. The returned sound waves are absorbed by the sound-absorbing layer again, thus effectively reducing the transmission of sound waves.

The sound absorbing layer and/or the sound insulating layer includes a foamed material.

Further, on the basis of the above embodiments, the sound insulating layer and/or the sound absorbing layer include foamed materials.

Specifically, in this embodiment, both the sound insulating layer and the sound absorbing layer may be foamed materials, and of course one of them may be foamed materials. The foamed material can be combined with the elastic powder 211 or with the elastic particles. Foaming material, elastic particles and elastic powder 211 can be separately arranged. It can also be mixed, that is, during the foaming process of the foamed material, an appropriate amount of elastic powder 211 and elastic particles are added to it, so that the elastic powder 211 and elastic particles are included in the foamed material, so that the formed foamed material not only It has the function of sound absorption and sound insulation.

The foaming material in this embodiment is made of isocyanate and polyether as the main raw materials. Under the action of various auxiliary agents such as foaming agent, catalyst, flame retardant, etc., it is mixed by special equipment and foamed on site by high-pressure spraying. High polymer. There are two types of polyurethane foams: soft foam and hard foam. In this embodiment, it is a soft foam, and the soft foam has an open-cell structure. The foamed material can be adhered to the surface of the casing 151 of the compressor 160 and tightly fixed with the casing 151 . At the same time, after the foam material wraps the compressor 160, the compressor 160 and the foam material form a whole, which can be easily moved, installed and disassembled.

The foam material itself is soft and elastic, which can convert the vibration energy of the compressor 160 into the elastic potential energy of the foam material; in addition, the foam material has an open-cell structure, and the vibration of the compressor 160 will be transmitted along the extension direction of the open-cell structure, During the vibration transmission process, the hole wall continuously consumes the vibration energy through repeated elastic deformation and restoration, and the foam material in contact with the casing 151 will vibrate to a certain extent during the vibration reduction process, so that the compressor 160 will be vibrated to a certain extent. The energy of the vibration is converted into one or more of kinetic energy, potential energy or thermal energy; at the same time, the elastic powder 211 and elastic particles contained in the foam material are also repeatedly elastically deformed and restored, converting the vibration energy into potential energy, thermal energy Or one or more of the kinetic energy, the energy of the vibration is continuously consumed so that the vibration is continuously weakened; in the same way, due to the vibration of the compressor 160 casing 151, the sound generated by the vibration of the foamed material, in the sound wave transmission. During the process, its energy will also be converted into heat or potential energy, so that the volume of the sound that can be transmitted is low.

Among them, ① indicates the noise level of the outdoor unit when the metal is bare; ③ indicates the noise level of the outdoor unit when the sound-absorbing layer and/or sound insulation layer includes foam materials; ⑤ indicates when the sound-absorbing layer and/or sound insulation layer includes foam materials and rubber powder The noise level of the outdoor unit; Figure 7 is a comparison diagram of the noise curve of the outdoor unit corresponding to Table 2.

Specifically, in this embodiment, both 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. Of course, in some embodiments, the sound insulation layer and the sound absorption layer can be mixed into one layer , this layer can be called a noise reduction layer, that is, the noise reduction layer has both the function of sound absorption and sound insulation. The elastic 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 it is between particles or between powder particles and powder particles, there are gaps. When sound passes through the particle layer or powder layer, the sound wave will bypass the particles or powder and propagate in the channel formed by the above-mentioned gap connection. , in the process of sound wave propagation, its energy is absorbed by powder or particle, powder or particle converts the ability of sound wave into one or more of potential energy, kinetic energy or thermal energy. Due to the large number of particles and powders, there are many channels through which the sound waves can be transmitted, so that the sound waves are in full contact with the particles, which is beneficial to increase the attenuation efficiency of the sound wave energy, thereby effectively reducing the transmission of noise. There is mutual extrusion and deformation between the elastic particles and the elastic powder 211 , so that the elastic particles and powder are pressed and fitted with the casing 151 , so that the elastic powder 211 and the particles are closely fitted with the casing 151 . When the electric structure assembly and the compression structure assembly drive the casing 151 to vibrate, the resistance that the drive casing 151 needs to overcome to generate vibration increases, which increases the damping of the vibration of the casing 151, so that the frequency of the compressor 160 vibration can be reduced; , the vibration of the housing 151 is transmitted through the elastic particles and powder in contact with it, and the vibration will drive the particles and powder to vibrate during the transmission process between the particles or between the powders, so that the particles and the powder are deformed, so that the particles and the powder are The friction occurs between them, and even the particles and powders are displaced, so that the energy of vibration is converted into kinetic energy, potential energy (including elastic potential energy) and thermal energy, which effectively attenuates the energy of vibration and reduces the vibration caused by transmission. noise.
