Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and more specifically to a compressor chamber assembly and an electrical device. Background Technology

[0002] In related technologies, refrigerator compressor compartments typically contain components that generate significant noise, such as fans and compressors. Furthermore, to meet heat exchange requirements, air inlets and outlets need to be installed on the walls of the compressor compartment, which in turn leads to excessive noise. Summary of the Invention

[0003] The present invention aims to at least solve or improve one of the technical problems of excessive internal noise in the compressor compartment of refrigerators in the prior art.

[0004] Therefore, a first aspect of the present invention provides a compressor compartment assembly.

[0005] A second aspect of the present invention provides an electrical device.

[0006] In view of the above, according to a first aspect of the present invention, a compressor chamber assembly is provided, comprising: a chamber wall having a compressor cavity inside, and the chamber wall having a first opening and a second opening communicating with the compressor cavity; a compressor disposed in the compressor cavity; an air inlet pipe disposed in the compressor cavity, the end of the air inlet pipe having a first air inlet hole, the side wall of the air inlet pipe having a first air outlet hole, the first air inlet hole and the first opening being connected, and the first air outlet hole facing the compressor; and an air outlet pipe disposed in the compressor cavity, the opposite ends of the air outlet pipe having a second air inlet hole and a second air outlet hole respectively, the second air outlet hole and the second opening being connected, and the second air inlet hole communicating with the compressor cavity.

[0007] The compressor chamber assembly proposed in this invention includes a chamber wall, a compressor, an air inlet pipe, and an air outlet pipe. The chamber wall has a first opening and a second opening, and the chamber wall forms a compressor chamber. The compressor is placed in the compressor chamber. The first opening and the second opening are connected to the compressor chamber. The air inlet pipe and the air outlet pipe are both arranged in the compressor chamber. The air inlet pipe is connected to the first opening, and the air outlet pipe is connected to the second opening. That is, the compressor chamber receives air through the air inlet pipe and discharges air through the air outlet pipe, thereby realizing the heat exchange function of the compressor chamber.

[0008] The air inlet duct has a first air inlet and a first air outlet. The first air inlet is connected to a first opening, allowing airflow to enter the first air inlet through the first opening and flow into the compressor chamber through the first air outlet. Noise from the compressor chamber is transmitted outward through the first air outlet and partially reflected by the side wall of the air inlet duct (excluding the first air outlet), thus reducing noise in the compressor chamber assembly. Furthermore, the first air inlet is located at the end of the air inlet duct, and the first air outlet is located on the side wall of the air inlet duct. Therefore, the first air inlet and the first air outlet are not directly opposite each other; the first air outlet corresponds to the other side wall of the air inlet duct. Consequently, noise from the compressor chamber entering the air inlet duct is further reflected by the other side wall of the air inlet duct, further reducing noise in the compressor chamber assembly.

[0009] The air outlet duct has a second air inlet and a second air outlet, which are respectively located at opposite ends of the air outlet duct. This allows the air outlet duct and the compressor chamber to form an expansion chamber acoustic structure, so that the duct wall can also reflect the noise inside the compressor chamber, thereby improving the noise reduction effect on the compressor chamber components.

[0010] In addition, the compressor chamber assembly according to the above-described technical solution provided by the present invention may also have the following additional technical features:

[0011] Based on the above technical solution, further, along the direction from the second opening to the first opening, the compressor is located on the side of the air outlet pipe.

[0012] In this technical solution, the compressor is located on the side of the air outlet pipe along the direction from the second opening to the first opening. The second air inlet and the second air outlet on the air outlet pipe are opposite to each other, and the second air outlet and the second opening are connected. Thus, the compressor is located on the side of the air outlet pipe. In other words, the second air inlet does not face the compressor. Therefore, the noise generated by the compressor is reflected by the side wall of the air outlet pipe and will not directly enter the second air inlet and be transmitted out, thereby further improving the noise reduction effect on the compressor compartment components.

[0013] Based on any of the above technical solutions, further, the number of first air outlets is multiple, and the multiple first air outlets are distributed in multiple rows along the direction from near the first air inlet to away from the first air inlet.

[0014] In this technical solution, there are multiple first air outlets. These multiple first air outlets are arranged in an array from one end of the air inlet pipe where the first air inlet is located to the end opposite to the first air inlet. Thus, there are multiple first air outlets on the side of the air inlet pipe facing the compressor. In other words, the sidewall of the air inlet pipe has a mesh structure. As a result, the pipe wall of the air inlet pipe located between adjacent first air outlets can reflect noise, thereby improving the noise reduction effect on the compressor compartment components.

[0015] Furthermore, this arrangement can also filter out some of the impurities in the airflow.

[0016] Based on any of the above technical solutions, further, the ventilation area of ​​the first air outlet closer to the first air inlet is greater than the ventilation area of ​​the first air outlet farther from the first air inlet.

[0017] In this technical solution, among the multiple first air inlets, the ventilation area of ​​the first air outlet closest to the first air inlet is greater than the ventilation area of ​​the first air outlet furthest from the first air inlet.

[0018] In other words, the ventilation area of ​​multiple first air outlets gradually decreases from the direction closest to the first air inlet to the direction furthest from the first air inlet, so as to adjust the wind speed distribution in the compressor chamber and improve the uniformity of airflow.

[0019] Based on any of the above technical solutions, the first air outlet is further defined as a polygonal hole, a circular hole, an elliptical hole, or a waist-shaped hole.

[0020] In this technical solution, the first air outlet can be a polygonal hole, a circular hole, an elliptical hole, or a waist-shaped hole.

[0021] Based on any of the above technical solutions, the air inlet pipe further includes a third air outlet, which is located on the side wall of the air inlet pipe, on one side of the first air outlet.

[0022] In this technical solution, the air inlet pipe also includes a third air outlet, which is located on the side wall of the air inlet pipe and on the same side as the first air outlet. The third air outlet increases the air intake of the air inlet pipe, thereby meeting the needs of the compressor compartment components.

[0023] Based on any of the above technical solutions, the air inlet pipe is further defined as a polygonal pipe, a circular pipe, or an elliptical pipe; the air outlet pipe is defined as a polygonal pipe, a circular pipe, or an elliptical pipe.

[0024] In this technical solution, the air inlet pipe adopts a polygonal pipe, a circular pipe or an elliptical pipe, and the air outlet pipe adopts a polygonal pipe, a circular pipe or an elliptical pipe.

[0025] In addition to any of the above technical solutions, it further includes: a partition net installed in the air outlet duct.

[0026] In this technical solution, the compressor chamber assembly also includes a mesh screen installed in the air outlet duct. The mesh screen can block debris and also rectify the airflow discharged from the compressor chamber assembly through the air outlet duct.

[0027] Based on any of the above technical solutions, the mesh further includes multiple ventilation holes, which are polygonal, circular, elliptical, or oblong.

[0028] In this technical solution, the mesh has multiple ventilation holes, which facilitate the rectification of the airflow discharged through the air outlet pipe. The ventilation holes can be polygonal, circular, elliptical, or oblong.

[0029] Based on any of the above technical solutions, the first opening and the second opening are further located on the same side wall of the bulkhead.

[0030] In this technical solution, the first opening and the second opening are located on the same side of the bulkhead, which facilitates the installation of the compressor compartment components on the electrical equipment.

[0031] Based on any of the above technical solutions, it further includes: a sealing plate, which is disposed on the air inlet pipe and located at the end of the air inlet pipe opposite to the first air inlet hole.

[0032] In this technical solution, the compressor chamber assembly also includes a sealing plate connected to the air inlet pipe, thereby blocking the end of the air inlet pipe away from the first air inlet hole, so that the air outlet of the air inlet pipe is only the first air outlet hole, or the first air outlet hole and the third air outlet hole, thereby improving the airflow effect in the compressor chamber. Furthermore, since the side of the air inlet pipe away from the first air inlet hole is blocked, the noise reduction effect on the compressor chamber assembly is further improved.

[0033] Based on any of the above technical solutions, it further includes: a resonator, disposed in the air outlet duct and / or air inlet duct.

[0034] In this technical solution, the compressor chamber assembly also includes a resonator installed on the air outlet pipe and / or air inlet pipe, which enhances the noise reduction effect of the compressor chamber assembly.

[0035] According to a second aspect of the present invention, an electrical device is provided, comprising: a compressor chamber assembly as described in any of the above-described technical solutions.

[0036] The electrical device proposed in this invention, as described in any of the above technical solutions, has all the beneficial effects of the electrical device described in any of the above technical solutions, which will not be described in detail here.

Detailed Implementation

[0050] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0052] The following reference Figures 1 to 9 This describes the compressor chamber assembly 100 and electrical equipment provided according to some embodiments of the present invention.

[0053] like Figure 1 As shown, the present invention provides a compressor chamber assembly 100, including: a chamber wall 110, a compressor 120, an air inlet pipe 130, and an air outlet pipe 140. A compressor chamber 116 is formed on the chamber wall 110. The compressor 120, the air inlet pipe 130, and the air outlet pipe 140 are all installed in the compressor chamber 116 and connected to the chamber wall 110. A first opening 112 and a second opening 114 are provided on the chamber wall 110. The air inlet pipe 130 is connected to the chamber wall 110 and communicates with the first opening 112. The air outlet pipe 140 is connected to the chamber wall 110 and communicates with the second opening 114.

[0054] The air inlet pipe 130 is provided with a first air inlet hole 132 and a first air outlet hole 134. The first air inlet hole 132 is connected to the first opening 112, and the first air outlet hole 134 is located inside the compressor chamber 116. Thus, the air inlet pipe 130 draws in air through the first opening 112 and vents air into the compressor chamber 116 through the first air outlet hole 134.

[0055] The air outlet pipe 140 is provided with a second air inlet 142 and a second air outlet 144. The second air outlet 144 is connected to the second opening 114. The second air inlet 142 is located inside the compressor chamber 116. Thus, the air outlet pipe 140 draws in air in the compressor chamber 116 and discharges it through the second opening 114.

[0056] Furthermore, the first air inlet 132 is located at the end of the air inlet pipe 130, and the first air outlet 134 is located on the side wall of the air inlet pipe 130. This means the first air inlet 132 and the first air outlet 134 are not on a straight line. Therefore, noise from the compressor chamber 116 will not directly pass through the air inlet pipe 130, but will be reflected off the pipe wall, thus reducing noise. The first air outlet 134 faces the compressor 120, facilitating airflow.

[0057] The second air inlet 142 and the second air outlet 140 are respectively located at opposite ends of the air outlet 140, that is, the second air inlet 142 and the second air outlet 144 are on the same straight line. The bulkhead 110 and the air outlet 140 form an expansion cavity acoustic structure, thereby reducing noise.

[0058] The compressor chamber assembly 100 provided by the present invention includes a chamber wall 110, a compressor 120, an air inlet pipe 130, and an air outlet pipe 140. The chamber wall 110 has a first opening 112 and a second opening 114, and the chamber wall 110 forms a compressor chamber 116. The compressor 120 is placed in the compressor chamber 116. The first opening 112 and the second opening 114 are connected to the compressor chamber 116. The air inlet pipe 130 and the air outlet pipe 140 are both arranged in the compressor chamber 116. The air inlet pipe 130 is connected to the first opening 112, and the air outlet pipe 140 is connected to the second opening 114. That is, the compressor chamber 116 receives air through the air inlet pipe 130 and discharges air through the air outlet pipe 140, thereby realizing the heat exchange function of the compressor chamber 116.

[0059] The air inlet duct 130 has a first air inlet hole 132 and a first air outlet hole 134. The first air inlet hole 132 is connected to a first opening 112, so that airflow can enter the first air inlet hole 132 through the first opening 112 and flow into the compressor chamber 116 through the first air outlet hole 134. The noise in the compressor chamber 116 is transmitted outward through the first air outlet hole 134 in the opposite direction, and part of it is reflected by the side wall of the air inlet duct 130 other than the first air outlet hole 134, thereby achieving the function of noise reduction in the compressor chamber assembly 100. To reduce noise, the first air inlet 132 is located at the end of the air inlet pipe 130, and the first air outlet 134 is located on the side wall of the air inlet pipe 130. Thus, the first air inlet 132 and the first air outlet 134 are not directly opposite each other. The first air outlet 134 corresponds to the side wall of the air inlet pipe 130 on the other side. Therefore, after the noise in the compressor chamber 116 enters the air inlet pipe 130, it will be partially reflected again by the side wall of the air inlet pipe 130, thereby further reducing the noise of the compressor chamber assembly 100.

[0060] The air outlet duct 140 has a second air inlet 142 and a second air outlet 144. The second air inlet 142 and the second air outlet 144 are respectively located at opposite ends of the air outlet duct 140. Thus, the air outlet duct 140 and the compressor chamber 116 form an expansion chamber acoustic structure, so that the pipe wall of the air outlet duct 140 can also reflect the noise in the compressor chamber 116, thereby improving the noise reduction effect on the compressor chamber assembly 100.

[0061] The air inlet pipe 130 and the air outlet pipe 140 can ensure normal heat dissipation within the compressor compartment assembly 100, and their structure is simple and easy to process.

[0062] Furthermore, along the direction from the second air inlet 142 to the second air outlet 144, the length of the air outlet 140 is less than the length of the air inlet 130.

[0063] like Figure 1As shown, in one possible embodiment of the present invention, along the direction from the second opening 114 to the first opening 112, the compressor 120 is located on the side of the air outlet duct 140, that is, the second air inlet 142 on the air outlet duct 140 is not directly facing the compressor 120. Specifically, along the direction from the second opening 114 to the first opening 112, the compressor 120 is located between the air inlet duct 130 and the air outlet duct 140, with one side of the compressor 120 facing the first air outlet 134, and the other side of the compressor 120 facing one side of the air outlet duct 140.

[0064] In this embodiment, along the direction from the second opening 114 to the first opening 112, the compressor 120 is disposed on the side of the air outlet duct 140. The second air inlet 142 and the second air outlet 144 on the air outlet duct 140 are opposite to each other, and the second air outlet 144 is connected to the second opening 114. Thus, the compressor 120 is located on the side of the air outlet duct 140, that is, the second air inlet 142 is not facing the compressor 120. Therefore, the noise generated by the compressor 120 is reflected by the side wall of the air outlet duct 140 and will not directly enter the second air inlet 142 and be transmitted out, thereby further improving the noise reduction effect on the compressor chamber assembly 100.

[0065] like Figure 2 , Figure 3 and Figure 4 As shown, in one possible embodiment of the present invention, the air inlet pipe 130 is provided with a plurality of first air outlet holes 134.

[0066] In this embodiment, there are multiple first air outlets 134, meaning the sidewall of the air inlet pipe 130 has a mesh structure. This allows the pipe walls of the air inlet pipes 130 located between adjacent first air outlets 134 to reflect noise, thereby improving the noise reduction effect on the compressor chamber assembly 100. Noise within the compressor chamber 116 propagates outward through the first air outlets 134 and is partially reflected by the pipe walls between the first air outlets 134 on the sidewall of the air inlet pipe 130, thus achieving noise reduction for the compressor chamber assembly 100.

[0067] Furthermore, this arrangement can also filter out some of the impurities in the airflow.

[0068] Furthermore, on the side wall of the air inlet pipe 130, multiple rows of first air outlet holes 134 are arranged side by side in the direction from the direction towards the first air inlet hole 132 to the direction away from the first air inlet hole 132.

[0069] In this embodiment, there are multiple first air outlet holes 134. The multiple first air outlet holes 134 are arranged in an array from one end of the air inlet pipe 130 where the first air inlet hole 132 is located, towards the end opposite to the first air inlet hole 132. Thus, there are multiple first air outlet holes 134 on the side of the air inlet pipe 130 facing the compressor 120, thereby ensuring the ventilation and heat exchange function of the compressor chamber 116.

[0070] In other words, it can improve the airflow state of the compressor chamber intake, enhance the uniformity of airflow, and ensure the heat dissipation effect of the heat exchanger 170 and the stable operation of the fan 180.

[0071] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a possible embodiment of the present invention, on the side wall of the air inlet pipe 130, the ventilation area of ​​the first air outlet 134 on the side closer to the first air inlet 132 is greater than the ventilation area of ​​the first air outlet 134 on the side farther away from the first air inlet 132.

[0072] In this embodiment, among the plurality of first air inlets 132, the ventilation area of ​​a first air outlet 134 closer to the first air inlet 132 is greater than the ventilation area of ​​a first air outlet 134 farther away from the first air inlet 132.

[0073] That is, from the direction closer to the first air inlet 132 to the direction farther away from the first air inlet 132, the ventilation area of ​​the multiple first air outlets 134 gradually decreases, so as to adjust the wind speed distribution in the compressor chamber 116 and improve the airflow uniformity.

[0074] Specifically, such as Figure 5 As shown, the first air outlet 134 is a circular hole. The first air outlet 134A is closer to the first air inlet 132 than the first air outlet 134B, and the first air outlet 134B is farther away from the first air inlet 132 than the first air outlet 134A. If the first air outlet 134 is a circular hole, then the diameter of the first air outlet 134A is larger than the diameter of the first air outlet 134B.

[0075] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a possible embodiment of the present invention, the first air outlet 134 is a polygonal hole, or the first air outlet 134 is a circular hole, or the first air outlet 134 is an elliptical hole, or the first air outlet 134 is an oblong hole.

[0076] In this embodiment, the first air outlet 134 is a polygonal hole, such as a triangular hole, a quadrilateral hole, a pentagonal hole, or a hexagonal hole, etc.

[0077] Alternatively, the first air outlet 134 can be a round hole.

[0078] Alternatively, the first air outlet 134 can be an oval-shaped hole.

[0079] Alternatively, the first air outlet 134 can be a waist-shaped hole.

[0080] like Figure 2 and Figure 3 As shown, in one possible embodiment of the present invention, a third air outlet 136 is also provided on the side wall of the air inlet pipe 130, and the third air outlet 136 is located on one side of the first air outlet 134. Specifically, if the air inlet pipe 130 is a polygonal pipe, then the first air outlet 134 is located on one side wall of the air inlet pipe 130, and the third air outlet 136 is located on the other side wall of the air inlet pipe 130. Further, the first air outlet 134 and the third air outlet 136 are respectively provided on adjacent sides of the air inlet pipe 130, for example: the first air outlet 134 faces to the side, and the third air outlet 136 faces upward and / or downward.

[0081] In this embodiment, the air inlet pipe 130 also includes a third air outlet 136. The third air outlet 136 is disposed on the side wall of the air inlet pipe 130 and is located on one side of the first air outlet 134. The air intake of the air inlet pipe 130 is increased through the third air outlet 136, thereby meeting the needs of the compressor chamber assembly 100.

[0082] The third air outlet 136 may be a polygonal hole, a circular hole, an elliptical hole, or an oblong hole.

[0083] The third air outlet 136 adopts a polygonal shape, such as a triangular hole, a quadrilateral hole, a pentagonal hole, or a hexagonal hole, etc.

[0084] Alternatively, the third air outlet 136 can be a round hole.

[0085] Alternatively, the third air outlet 136 can be an oval-shaped hole.

[0086] Alternatively, the third air outlet 136 can be a waist-shaped hole.

[0087] Furthermore, the air inlet duct 130 is provided with multiple third air outlets 136.

[0088] In this embodiment, there are multiple third air outlets 136, that is, the sidewall of the air inlet pipe 130 has a mesh structure, and the pipe wall of the air inlet pipe 130 located between adjacent third air outlets 136 can reflect noise, thereby improving the noise reduction effect on the compressor chamber assembly 100.

[0089] Furthermore, this arrangement can also filter out some of the impurities in the airflow.

[0090] Furthermore, on the side wall of the air inlet pipe 130, multiple rows of third air outlets 136 are arranged side by side in the direction from the first air inlet hole 132 to the direction away from the first air inlet hole 132.

[0091] In this embodiment, there are multiple third air outlets 136. The multiple third air outlets 136 are arranged in an array from one end of the air inlet pipe 130 where the first air inlet 132 is located, towards the end opposite to the first air inlet 132, thereby increasing the ventilation area.

[0092] Furthermore, on the side wall of the air inlet duct 130, the ventilation area of ​​the third air outlet 136 on the side closer to the first air inlet 132 is greater than the ventilation area of ​​the third air outlet 136 on the side farther away from the first air inlet 132.

[0093] In this embodiment, among the plurality of first air inlets 132, the ventilation area of ​​a third air outlet 136 closer to the first air inlet 132 is greater than the ventilation area of ​​a third air outlet 136 farther away from the first air inlet 132.

[0094] That is, from the direction closer to the first air inlet 132 to the direction farther away from the first air inlet 132, the ventilation area of ​​the multiple third air outlets 136 gradually decreases, so as to adjust the wind speed distribution in the compressor chamber 116 and improve the airflow uniformity.

[0095] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one possible embodiment of the present invention, the air inlet pipe 130 is a polygonal pipe, or the air inlet pipe 130 is a circular pipe, or the air inlet pipe 130 is an elliptical pipe.

[0096] In this embodiment, the air inlet duct 130 is a polygonal duct, such as a triangular duct, a quadrilateral duct, a pentagonal duct, or a hexagonal duct.

[0097] Alternatively, the air inlet duct 130 can be a round pipe.

[0098] Alternatively, the air inlet duct 130 can be an elliptical tube.

[0099] And / or the air outlet duct 140 is a polygonal duct, or the air outlet duct 140 is a circular duct, or the air outlet duct 140 is an elliptical duct.

[0100] In this embodiment, the air outlet duct 140 is a polygonal duct, such as a triangular duct, a quadrilateral duct, a pentagonal duct, or a hexagonal duct.

[0101] Alternatively, the air outlet duct 140 can be a round tube.

[0102] Alternatively, the air outlet duct 140 can be an oval-shaped tube.

[0103] like Figure 6 , Figure 7 and Figure 8 As shown, in one possible embodiment of the present invention, a partition net 150 is provided in the air outlet duct 140.

[0104] In this embodiment, the compressor chamber assembly 100 also includes a partition 150 disposed in the air outlet duct 140. The partition 150 can block debris and also rectify the airflow discharged from the compressor chamber assembly 100 through the air outlet duct 140.

[0105] like Figure 7 As shown, in one possible embodiment of the present invention, a plurality of ventilation holes 152 are provided on the mesh 150.

[0106] In this embodiment, the mesh 150 has a plurality of ventilation holes 152, which facilitate the rectification of the airflow discharged through the air outlet duct 140.

[0107] The ventilation hole 152 can be a polygonal hole, a circular hole, an elliptical hole, or an oblong hole.

[0108] In this embodiment, the ventilation hole 152 is a polygonal hole, such as a triangular hole, a quadrilateral hole, a pentagonal hole, or a hexagonal hole.

[0109] Alternatively, ventilation hole 152 can be round.

[0110] Alternatively, ventilation hole 152 can be an oval shape.

[0111] Alternatively, ventilation hole 152 can be a waist-shaped hole.

[0112] like Figure 1 and Figure 9 As shown, in a possible embodiment of the present invention, the first opening 112 and the second opening 114 are both provided on the same side wall of the bulkhead 110, for example, the first opening 112 and the second opening 114 are both provided on the rear wall of the bulkhead 110.

[0113] In this embodiment, the first opening 112 and the second opening 114 are located on the same side of the bulkhead 110, thereby facilitating the installation of the compressor compartment assembly 100 on electrical equipment.

[0114] Specifically, the first opening 112 and the second opening 114 are arranged side by side, and the first opening 112 and the first air inlet 132 have the same shape and the same size, and the second opening 114 and the second air outlet 144 have the same shape and the same size.

[0115] like Figure 1 As shown, in one possible embodiment of the present invention, a sealing plate 160 is installed at the end of the air inlet pipe 130 away from the first air inlet hole 132 to seal the air inlet pipe 130.

[0116] In this embodiment, the compressor chamber assembly 100 also includes a sealing plate 160 connected to the air inlet pipe 130, thereby blocking the end of the air inlet pipe 130 away from the first air inlet hole 132, so that the air intake of the compressor chamber 116 is only in the first air outlet hole 134, or the first air outlet hole 134 and the third air outlet hole 136, thereby improving the airflow effect in the compressor chamber 116. Furthermore, since the side of the air inlet pipe 130 away from the first air inlet hole 132 is blocked, the noise reduction effect on the compressor chamber assembly 100 is further improved.

[0117] Specifically, the air inlet pipe 130 has openings at both ends, one end of which is the first air inlet hole 132 and the other end is blocked. The side wall is provided with a first air outlet hole 134 and a third air outlet hole 136. The sealing plate 160 can be an integral structure with the bulkhead 110, or the sealing plate 160 can be part of the bulkhead 110, or the sealing plate 160 can be independent.

[0118] like Figure 6 As shown, in one possible embodiment of the present invention, a resonator 190 is provided on the air outlet duct 140.

[0119] In this embodiment, the compressor chamber assembly 100 also includes a resonator 190 disposed on the air outlet duct 140, which enhances the noise reduction effect on the compressor chamber assembly 100.

[0120] Among them, the air outlet duct 140 can be a polygonal tube, which is conducive to the installation of the resonator 190.

[0121] As a possible embodiment of the present invention, a resonator 190 is provided on the air inlet pipe 130.

[0122] In this embodiment, the compressor chamber assembly 100 also includes a resonator 190 disposed on the air inlet duct 130, which enhances the noise reduction effect on the compressor chamber assembly 100.

[0123] The air inlet duct 130 can be a polygonal tube, which facilitates the installation of the resonator 190.

[0124] like Figure 1As shown, the compressor chamber assembly 100 provided by the present invention includes: a chamber wall 110, an air inlet pipe 130 and an air outlet pipe 140 disposed on the chamber wall 110. The air inlet end is a relatively long square straight pipe placed between the heat exchanger 170 and the side cover plate. One end of the air inlet pipe 130 is open and connected to the rear cover plate of the chamber wall 110, and communicates with the outside to realize air intake. The other end of the air inlet pipe 130 is closed and connected to the inner wall surface of the air inlet pipe 130. Circular holes are opened on the top and the side wall surface near the condenser for compressor chamber ventilation. The air outlet pipe 140 is a relatively short square straight pipe placed between the compressor 120 and the other side cover plate of the chamber wall 110. Both ends of the air inlet pipe 130 are open. One end of the air inlet pipe 130 is connected to the rear cover plate of the chamber wall 110, and the other end of the air inlet pipe 130 is placed in the compressor chamber 116.

[0125] like Figure 2 and Figure 3 As shown, when noise from sources such as the fan 180 and compressor 120 inside the bulkhead 110 propagates towards the air inlet duct 130, most of it is reflected by the side wall of the air inlet duct 130. Only a small portion passes through the first air outlet 134 and the third air outlet 136 to propagate outside the bulkhead 110, thereby achieving sound insulation and noise reduction of the compressor compartment assembly 100. Simultaneously, the air inlet duct 130 is implemented by setting circular holes in the side wall of a square straight pipe. These circular holes feature a variable diameter design, gradually decreasing in diameter along the air inlet direction, from the rear cover plate of the bulkhead 110 to the inner wall surface. This achieves the purpose of adjusting the internal airflow distribution of the compressor compartment assembly 100 and improving airflow uniformity.

[0126] like Figure 6 , Figure 7 and Figure 8 As shown, the air outlet duct 140 is a square straight pipe with a cross-shaped mesh 150 inside. When noise from the compressor chamber assembly 100 propagates to the air outlet duct 140, the air outlet duct 140 and the compressor chamber 116 form an expansion cavity acoustic structure. The noise is partially reflected by the side wall of the square straight pipe and the wall of the chamber wall 110, thereby achieving sound insulation and noise reduction of the compressor chamber assembly 100. The cross-shaped mesh 150 inside the square pipe not only blocks foreign objects but also rectifies the airflow from the compressor chamber assembly 100, which is beneficial for arranging a resonator 190 sound-absorbing structure on the side wall of the outlet end of the air outlet duct 140.

[0127] The compressor chamber assembly 100 provided by the present invention can reduce the noise of the compressor chamber assembly 100 by setting the air inlet pipe 130 and the air outlet pipe 140. In addition, it is easy to process and install, and can make use of the limited space of the compressor chamber assembly 100 to adapt to the basic structural layout of the compressor chamber assembly 100.

[0128] Specifically, the compressor chamber assembly 100 provided by the present invention has good low-to-mid frequency noise reduction function, and can achieve a noise reduction effect of more than 1.5dB in the 0-6400Hz frequency band. Moreover, the noise reduction frequency band is concentrated below 2000Hz. It can be easily used in conjunction with noise reduction structures such as resonator 190 and sound-absorbing cotton. The side walls of the air inlet pipe 130 and the air outlet pipe 140 can be easily installed with the sound-absorbing structure of resonator 190 to enhance the noise reduction effect.

[0129] The compressor chamber assembly 100 can ensure ventilation and heat dissipation of the compressor chamber 116. The air inlet pipe 130 can improve the airflow state on the air inlet side of the compressor chamber assembly 100, improve the airflow uniformity around the heat exchanger 170, ensure the heat dissipation effect of the heat exchanger 170 and the stable operation of the fan 180. The air outlet pipe 140 can also ensure good heat dissipation of the compressor 120 under the swirling condition on the outlet side of the fan 180.
