Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of mufflers, and in particular, to a muffler, a compressor, and an air conditioner. Background Art

[0002] The compressor is a key component of an air conditioner. Due to its operating principles, the noise it produces during operation affects the quietness of the compressor and the air conditioner. Specifically, refrigerant enters the compressor casing through the external intake port, causing the noise from the intake port to be transmitted to the intake hood.

[0003] At present, the air intake hood of the compressor in the related art is a simple cavity structure with a close distance between the inlet and outlet, and the noise reduction effect is poor. Summary of the Invention

[0004] The embodiments of the present invention aim to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the present invention provides a muffler.

[0006] A second aspect of an embodiment of the present invention provides a compressor.

[0007] A third aspect of an embodiment of the present invention provides an air conditioner.

[0008] In view of this, according to a first aspect of an embodiment of the present invention, a silencer is provided, which includes: a shell having a silencer chamber; an air inlet and an air outlet, which are arranged in the shell and are respectively connected to the silencer chamber; a baffle assembly, which is arranged in the silencer chamber and divides the silencer chamber into a plurality of mutually connected silencer channels, at least one silencer channel is connected to the air inlet, and at least one silencer channel is connected to the air outlet.

[0009] The muffler provided in an embodiment of the present invention includes a housing, an air inlet, an air outlet, and a baffle assembly. Specifically, the air inlet and the air outlet are both disposed on the housing, and the housing is provided with a muffler cavity, and the air inlet and the air outlet are respectively connected to the muffler cavity. It is understood that airflow enters the muffler cavity through the air inlet and is discharged through the air outlet.

[0010] The baffle assembly is disposed within the muffler chamber and divides the chamber into a plurality of muffler channels, each of which is interconnected. At least one muffler channel is connected to the air inlet, and at least one muffler channel is connected to the air outlet. In other words, air enters through the air inlet, flows through the plurality of muffler channels, and is discharged from the air outlet.

[0011] It can be understood that the baffle assembly divides the silencer cavity into multiple silencer channels, that is, the baffle assembly divides the larger silencer cavity into multiple interconnected smaller silencer channels. After the airflow flows into the smaller silencer channel, the sound waves can be offset by multiple reflections and interferences in the smaller silencer channel. After the airflow is silenced by a smaller silencer channel, it can also flow through the remaining silencer channels for further silencing, thereby achieving the purpose of noise reduction.

[0012] That is to say, by setting up a baffle assembly, the silencer chamber is divided into multiple silencer channels, so that after the airflow enters from the air inlet, it can change the flow path of the airflow in the silencer chamber multiple times without increasing the airflow resistance, thereby extending the flow time of the airflow in the silencer chamber, and thus making the sound waves cancel out after multiple reflections and interferences in the multiple silencer channels, thereby improving the silencer effect of the airflow flowing through the silencer, and can significantly improve the transmission loss of the medium and high frequencies of the compressor in which the silencer is set between the air intake and the stator opening, thereby improving the silencer volume of the entire compressor.

[0013] In practice, the muffler is located between the compressor's intake port and the opening of the stator. Specifically, the intake port is connected to the intake port, and the opening is connected to the outlet port. During the compressor's intake process, air flows through the intake port into the intake port, flows out through multiple muffler channels to the outlet, and enters the compression chamber through the opening of the stator plate. By installing a baffle assembly within the muffler chamber, the number of airflow reflections within the multiple muffler channels can be increased, extending the airflow's flow time within the muffler chamber and improving the noise reduction effect during the compressor's intake process.

[0014] In addition, the first part of the baffle assembly is arranged close to the air inlet, that is, the silencer channel is arranged close to the air inlet, so that the silencer can start as soon as the air flow enters the air inlet, further extending the flow time of the air flow in the silencer chamber, increasing the number of reflections of the sound waves in multiple silencer channels, and improving the silencer effect.

[0015] The second part of the baffle assembly is arranged close to the air outlet, so that the air flow can be silenced again in the process of flowing out through the air outlet, further extending the flow time of the air flow in the silencer chamber, increasing the number of reflections of the sound waves during the flow process, and further improving the sound attenuation.

[0016] It is worth noting that at least one silencer channel is connected to the air inlet, and at least one silencer channel is connected to the air outlet. It is understood that each of the multiple silencer channels is connected to both the air inlet and the air outlet. Alternatively, the multiple silencer channels include a first silencer channel, a second silencer channel, and multiple third silencer channels, wherein the first silencer channel is connected to the air inlet, the second silencer channel is connected to the air outlet, and the multiple third silencer channels are connected to each other and to the first and second silencer channels, respectively. Specific configurations can be made based on actual needs.

[0017] In addition, the muffler provided according to the above technical solution of the present invention also has the following additional technical features:

[0018] In a possible technical solution, the baffle assembly includes a first baffle, which is arranged close to the air inlet and inserted into the muffler cavity along the air inlet direction of the air flow at the air inlet.

[0019] In this technical solution, it is defined that the baffle assembly includes a first baffle. Specifically, the first baffle is arranged close to the air inlet, that is, the silencer channel begins to be separated near the air inlet, that is, the silencer channel is arranged close to the air inlet, so that the silencer can start as soon as the air flow enters the air inlet, further extending the flow time of the air flow in the silencer cavity, increasing the number of reflections of the sound waves in multiple silencer channels, and improving the silencer effect.

[0020] Along the air intake direction of the air flow at the air inlet, the first baffle is inserted into the silencer chamber, that is, the first end of the first baffle is arranged close to the air inlet, and the second end of the first baffle extends into the silencer chamber along the axial direction of the air inlet, so that the flow path of the air flow in the silencer chamber can be changed multiple times without increasing the air flow resistance, and the flow time of the air flow in the silencer chamber can be extended, so that the sound waves are offset by multiple reflections and interferences in multiple silencer channels, thereby improving the silencer effect of the air flow passing through the silencer, and can significantly improve the transmission loss of the medium and high frequencies of the compressor in which the silencer is arranged between the air intake and the stator opening, thereby improving the silencer volume of the entire compressor.

[0021] It can be understood that there is a preset distance between the inner wall of the shell opposite to the air inlet and the second end of the first baffle, that is, along the insertion direction of the first baffle, the insertion depth of the first baffle cannot be too deep, so as to improve the noise reduction effect of the air flow passing through the muffler without increasing the flow resistance of the air flow.

[0022] Alternatively, the first baffle and the shell are in contact with the inner side wall opposite to the air inlet, and a connecting hole is opened on the first baffle, which is connected to the air inlet and multiple silencer channels, thereby improving the noise reduction effect of the airflow flowing through the silencer without increasing the flow resistance of the airflow.

[0023] In a possible technical solution, the first end of the first baffle is arranged at the air inlet and divides the air inlet into at least two sub-air inlets, at least two sub-air inlets are respectively connected to multiple silencer channels, and the second end of the first baffle is inserted into the silencer cavity.

[0024] In this technical solution, the first end of the first baffle is located at the air inlet, and the first baffle divides the air inlet into at least two sub-air inlets, and the at least two sub-air inlets are respectively connected to multiple silencer channels, and the second end of the first baffle is inserted into the silencer cavity, that is, at least one silencer channel extends to the air inlet, which is beneficial to extend the airflow path while increasing the length of the silencer channel, thereby increasing the flow time of the airflow in multiple silencer channels, and then increasing the number of reflections of sound waves in the silencer pipeline, thereby improving the silencer effect.

[0025] Along the air intake direction of the air flow at the air inlet, the first baffle is inserted into the silencer chamber, that is, the first end of the first baffle is located at the air inlet, and the second end of the first baffle extends into the silencer chamber along the axial direction of the air inlet, so that the flow path of the air flow in the silencer chamber can be changed multiple times without increasing the air flow resistance, and the flow time of the air flow in the silencer chamber can be extended, so that the sound waves are offset by multiple reflections and interferences in multiple silencer channels, thereby improving the silencer effect of the air flow passing through the silencer, and can significantly improve the transmission loss of the medium and high frequencies of the compressor in which the silencer is arranged between the air intake and the stator opening, thereby improving the silencer volume of the entire compressor.

[0026] In a possible technical solution, the shell includes a first plate body and a second plate body arranged opposite to each other, the air inlet is arranged on the first plate body, and the air outlet is arranged on the second plate body; along the direction from the first plate body to the second plate body, the distance H between the inner side wall of the first plate body and the inner side wall of the second plate body and the height h of the first baffle satisfy h>H / 2.

[0027] In this technical solution, the housing includes a first plate and a second plate, wherein the first plate and the second plate are arranged opposite each other, the air inlet is arranged on the first plate, and the air outlet is arranged on the second plate. Because the first end of the first baffle is located at the air inlet, that is, at least one muffler channel extends to the air inlet, arranging the air inlet and the air outlet on two opposing plates of the housing further prolongs the flow path of the airflow within the muffler, increases the flow time of the airflow within the muffler, and thus improves the muffler effect.

[0028] The height of the first baffle is greater than half the distance between the inner wall of the first plate and the inner wall of the second plate. This limits the insertion depth of the first baffle from the air inlet to the muffler chamber. This improves the muffler's sound absorption performance without increasing airflow resistance.

[0029] Moreover, the height of the first baffle is greater than 1 / 2 of the distance between the inner wall of the first plate body and the inner wall of the second plate body, that is, the distance between the second end of the first baffle and the inner wall of the second plate body is smaller, so that a cross-sectional mutation can be generated when the airflow flows through here, thereby changing the flow path of the airflow, so that the sound waves can be reflected and interfered in multiple silencer channels and offset, thereby improving the noise reduction effect of the silencer.

[0030] In a possible technical solution, the shell also includes a third plate and a fourth plate arranged opposite to each other, the third plate is connected to the first plate and the second plate, and the fourth plate is connected to the first plate and the second plate; the first baffle is connected to the third plate and / or the fourth plate.

[0031] In this technical solution, the housing further includes a third plate and a fourth plate. Specifically, the third plate and the fourth plate are disposed opposite each other, the third plate being connected to the first plate and the second plate, and the fourth plate being connected to the first plate and the second plate. Thus, the first plate, the second plate, the third plate, and the fourth plate enclose a sound-absorbing chamber.

[0032] The first baffle is connected to the third plate, thereby improving the structural stability and stiffness of the first baffle, preventing vibration of the first baffle due to the impact of airflow when flowing within the muffler chamber, thereby causing secondary noise. This further improves the muffler's muffler effect and reduces the suction noise of the compressor equipped with the muffler.

[0033] The first baffle is connected to the fourth plate, thereby further improving the structural stability and rigidity of the first baffle, preventing the first baffle from vibrating due to the impact of airflow when flowing within the muffler chamber, thereby causing secondary noise. This further improves the muffler's muffler effect and reduces the suction noise of the compressor equipped with the muffler.

[0034] In a possible technical solution, the air outlet and the air inlet are staggered along the direction from the first plate body to the second plate body.

[0035] In this technical solution, the air outlet and the air inlet are staggered along the direction from the first plate body to the second plate body. Since one end of the first baffle is located at the air inlet, that is, the silencer channel extends to the air inlet, by staggering the air inlet and the air outlet, it is beneficial to extend the air flow path while increasing the length of the silencer channel, thereby increasing the flow time of the air flow in multiple silencer channels, and then increasing the number of reflections of the sound waves in the silencer pipe, thereby improving the silencer effect.

[0036] It can be understood that the baffle assembly also includes a second baffle, which includes a first baffle portion. The first baffle portion is arranged close to the air outlet. Since the air outlet and the air inlet are staggered, the length of the silencer channel can be further increased, thereby increasing the number of reflections of the sound waves in the silencer pipe, and further improving the silencer effect.

[0037] In a possible technical solution, the baffle assembly further includes a second baffle, which includes a first baffle portion. The first baffle portion is arranged close to the air outlet and is inserted into the muffler cavity along the air outlet direction of the air flow at the air outlet.

[0038] In this technical solution, it is defined that the baffle assembly also includes a second baffle. Specifically, the second baffle includes a first baffle, which is arranged near the air outlet and inserted into the silencer cavity along the air outlet direction of the air flow at the air outlet. That is, along the direction from the first plate body to the second plate body, the first end of the first baffle is arranged near the air outlet, and the second end of the first baffle is inserted into the silencer cavity, that is, at least one silencer channel extends to a position near the air outlet, which is beneficial to extend the air flow path while increasing the length of the silencer channel, thereby increasing the flow time of the air flow in multiple silencer channels, and then increasing the number of reflections of the sound waves in the silencer pipe, thereby improving the silencer effect.

[0039] Moreover, the first baffle is arranged close to the air outlet, so that the flow path of the airflow in the silencer chamber can be changed multiple times without increasing the airflow resistance, thereby extending the flow time of the airflow in the silencer chamber, and thus making the sound waves cancel each other out after multiple reflections and interferences in multiple silencer channels, thereby improving the silencer effect of the airflow flowing through the silencer, and can significantly improve the transmission loss of the medium and high frequencies of the compressor in which the silencer is arranged between the air intake and the stator opening, thereby improving the silencer volume of the entire compressor.

[0040] In a possible technical solution, the first end of the first stopper is located at the air outlet and divides the air outlet into at least two sub-air outlets, at least two sub-air outlets are connected to multiple silencer channels, and the second end of the first stopper is inserted into the silencer cavity.

[0041] In this technical solution, the first end of the first stop is located at the air outlet, and the first stop divides the air outlet into at least two sub-air outlets, and at least two sub-air outlets are respectively connected to multiple silencer channels, and the second end of the first stop is inserted into the silencer cavity, that is, at least one silencer channel extends to the air outlet, which is beneficial to extend the airflow path while further increasing the length of the silencer channel, thereby increasing the flow time of the airflow in multiple silencer channels, and then increasing the number of reflections of sound waves in the silencer pipeline, thereby improving the silencer effect.

[0042] In a possible technical solution, the second baffle further includes a second stop portion, which is connected to the first stop portion and forms a preset angle with the first stop portion, and an end of the second stop portion away from the first stop portion extends toward the side where the air inlet is located.

[0043] In this technical solution, it is defined that the second baffle further includes a second stop portion. Specifically, the second stop portion is connected to the first stop portion, and a preset angle is formed between the second stop portion and the first stop portion. For example, the preset angle can be 90 degrees. In other words, the second baffle is a corner plate.

[0044] The end of the second stop away from the first stop extends toward the air inlet, that is, the end of the second stop away from the first stop extends toward the side where the first baffle is located. This divides the muffler cavity into multiple muffler channels. That is, the first baffle and the second baffle divide the muffler cavity with a larger volume into multiple interconnected muffler channels with smaller volumes. After the airflow flows into the muffler channels with smaller volumes, the sound waves can be offset by multiple reflections and interferences in the muffler channels with smaller volumes. Moreover, after the airflow is silenced by one muffler channel with smaller volumes, it can flow through the remaining muffler channels for further silencing, thereby achieving the purpose of noise reduction.

[0045] In practical applications, the extension length of the second stop portion can be adjusted according to the noise reduction frequency required by the compressor.

[0046] In a possible technical solution, the housing is a plastic housing; and / or the baffle assembly is a plastic baffle.

[0047] In this technical solution, the shell is a plastic shell, which facilitates the processing of the shell and can further reduce the production cost of the muffler.

[0048] The baffle assembly is a plastic baffle, which facilitates processing of the baffle assembly and can further reduce the production cost of the muffler.

[0049] Furthermore, the housing and baffle assembly can be an integrated structure. As will be appreciated, this integrated structure offers superior mechanical properties, further enhancing the stability of the connection between the baffle assembly and the housing, preventing vibration of the baffle assembly caused by the impact of airflow within the muffler cavity, which in turn can cause secondary noise. Furthermore, the integrated structure can facilitate the processing and production of the muffler, reducing its production costs.

[0050] According to a second aspect of the present invention, a compressor is provided, comprising a muffler as provided by any of the above technical solutions, thereby having all the beneficial technical effects of the muffler, which will not be described in detail here.

[0051] Furthermore, the compressor also includes a shell, a compression assembly and a driving member, wherein the shell is provided with an air intake port, the air intake port is connected to the air inlet, the compression assembly is arranged in the shell, the compression assembly includes a stator and a movable plate, the stator and the movable plate enclose a compression chamber, the stator is provided with an opening, the opening is connected to the compression chamber and the air outlet, and the driving member is connected to the movable plate.

[0052] The compressor provided by the embodiment of the present invention includes a muffler, a housing, a compression assembly and a driving member. Specifically, the compression assembly includes a stator and a movable plate, which enclose a compression chamber. The stator is provided with an opening connected to the compression chamber, and the opening is connected to the air outlet of the muffler. The housing is provided with an air intake port, which is connected to the air inlet of the muffler. When the compressor inhales air, the air flow enters the air inlet through the air intake port, is silenced by multiple muffler channels, and then is discharged to the opening through the air outlet, and enters the compression chamber through the opening. The driving member drives the movable plate to rotate relative to the stator to compress the gas in the compression chamber, and the compressed high-temperature and high-pressure gas is discharged through the exhaust port of the stator.

[0053] It can be understood that the driving component includes a motor and a crankshaft, the motor is connected to the crankshaft, and the crankshaft is connected to the moving plate.

[0054] Among them, the baffle assembly divides the silencer cavity into multiple silencer channels, that is, the baffle assembly divides the larger silencer cavity into multiple interconnected smaller silencer channels. After the airflow flows into the smaller silencer channel, the sound waves can be offset by multiple reflections and interferences in the smaller silencer channel. After the airflow is silenced by a smaller silencer channel, it can also flow through the remaining silencer channels for further silencing, thereby achieving the purpose of noise reduction.

[0055] That is to say, by setting up a baffle assembly, the silencer chamber is divided into multiple silencer channels, so that after the airflow enters from the air inlet, it can change the flow path of the airflow in the silencer chamber multiple times without increasing the airflow resistance, thereby extending the flow time of the airflow in the silencer chamber, and thus making the sound waves cancel out after multiple reflections and interferences in the multiple silencer channels, thereby improving the silencer effect of the airflow flowing through the silencer, and can significantly improve the transmission loss of the medium and high frequencies of the compressor in which the silencer is set between the air intake and the stator opening, thereby improving the silencer volume of the entire compressor.

[0056] In addition, the compressor provided by the above technical solution of the present invention also has the following additional technical features:

[0057] In a possible technical solution, the flow cross-sectional area of the air suction port is equal to the flow cross-sectional area of the air inlet port.

[0058] In this technical solution, the flow cross-sectional area of the suction port is equal to that of the inlet port, thereby ensuring the suction efficiency of the compressor. It is understood that if the flow cross-sectional area of the inlet port is larger than that of the suction port, the gas in the casing will easily flow into the inlet port during the compressor suction process, affecting the operation of the compressor.

[0059] If the flow cross-sectional area of the air inlet is smaller than the flow cross-sectional area of the air suction port, the flow resistance of the gas will increase and the suction efficiency of the compressor will decrease.

[0060] In a possible technical solution, the shell is provided with a relief opening, which is communicated with the air outlet, and a portion of the stator is located in the relief opening and abuts against the shell.

[0061] In this technical solution, the housing is provided with a relief opening that communicates with the air outlet. Specifically, a portion of the stator disc is located within the relief opening and abuts the housing. This relief opening prevents interference with the stator disc during installation of the muffler to the compressor. Furthermore, the abutment of the stator disc against the housing improves the structural stability of the muffler.

[0062] In actual application, the housing is further provided with a mounting portion, and the mounting portion is provided with a mounting hole, and the housing is mounted and fixed to the static disk through the mounting hole.

[0063] According to a third aspect of the present invention, an air conditioner is provided, comprising a compressor as provided by any of the above technical solutions, thereby having all the beneficial technical effects of the compressor, which will not be described in detail here.

[0064] Additional aspects and advantages of the present invention will be set forth in part in the following description and, in part, will be obvious from the following description, or may be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0074] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0075] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0076] Refer to the following Figures 1 to 6 The muffler 100, the compressor 200, and the air conditioner provided according to some embodiments of the present invention are described.

[0077] In one embodiment according to the present application, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a muffler 100 is proposed, which includes: a shell 110, the shell 110 having a muffler cavity 111; an air inlet 120 and an air outlet 130, which are provided in the shell 110 and are respectively connected to the muffler cavity 111; a baffle assembly 140, which is provided in the muffler cavity 111 and divides the muffler cavity 111 into a plurality of mutually connected muffler channels, at least one muffler channel is connected to the air inlet 120, and at least one muffler channel is connected to the air outlet 130.

[0078] The muffler 100 provided in an embodiment of the present invention includes a housing 110, an air inlet 120, an air outlet 130, and a baffle assembly 140. Specifically, the air inlet 120 and the air outlet 130 are both provided on the housing 110, and the housing 110 is provided with a muffler cavity 111. The air inlet 120 and the air outlet 130 are respectively communicated with the muffler cavity 111. It can be understood that the air flow enters the muffler cavity 111 through the air inlet 120 and is discharged through the air outlet 130.

[0079] Baffle assembly 140 is disposed within muffler chamber 111 and divides muffler chamber 111 into multiple muffler channels, each of which is interconnected. At least one muffler channel is connected to air inlet 120, and at least one muffler channel is connected to air outlet 130. In other words, air enters through air inlet 120, flows through the multiple muffler channels, and is discharged from air outlet 130.

[0080] It can be understood that the baffle assembly 140 divides the silencer chamber 111 into a plurality of silencer channels, that is, the baffle assembly 140 divides the silencer chamber 111 with a larger volume into a plurality of silencer channels with smaller volumes that are interconnected. After the airflow flows into the silencer channels with a smaller volume, the sound waves can be offset by multiple reflections and interferences in the silencer channels with a smaller volume. Moreover, after the airflow is silenced through a silencer channel with a smaller volume, it can also flow through the remaining silencer channels for further silencing, thereby achieving the purpose of noise reduction.

[0081] That is to say, by setting the baffle assembly 140, the silencer chamber 111 is divided into multiple silencer channels, so that after the airflow enters from the air inlet 120, it can change the flow path of the airflow in the silencer chamber 111 multiple times without increasing the airflow resistance, thereby extending the flow time of the airflow in the silencer chamber 111, and thus making the sound waves offset after multiple reflections and interferences in the multiple silencer channels, thereby improving the silencer effect of the airflow flowing through the silencer 100, and can significantly improve the transmission loss of the medium and high frequencies of the compressor 200 in which the silencer 100 is set between the air intake 211 and the opening 224 of the stator 221, thereby improving the silencer volume of the entire compressor 200.

[0082] In actual application, the muffler 100 is disposed between the air intake 211 of the compressor 200 and the opening 224 of the stator 221. Specifically, the air intake 120 is connected to the air intake 211, and the opening 224 is connected to the air outlet 130. During the air intake process of the compressor 200, the air flows into the air intake 120 through the air intake 211, flows out to the air outlet 130 through multiple muffler channels, and enters the compression chamber 223 through the opening 224 of the stator 221. By providing the baffle assembly 140 within the muffler chamber 111, the number of reflections of the airflow within the multiple muffler channels can be increased, the flow time of the airflow within the muffler chamber 111 can be extended, and the noise reduction effect during the air intake process of the compressor 200 can be improved.

[0083] In addition, the first part of the baffle assembly 140 is arranged close to the air inlet 120, that is, the silencer channel is arranged close to the air inlet 120, so that the silencer can start as soon as the air flow enters the air inlet 120, further extending the flow time of the air flow in the silencer chamber 111, increasing the number of reflections of the sound waves in multiple silencer channels, and improving the silencer effect.

[0084] The second part of the baffle assembly 140 is arranged close to the air outlet 130, so that the air flow can be silenced again in the process of flowing out through the air outlet 130, further extending the flow time of the air flow in the silencer chamber 111, increasing the number of reflections of the sound waves during the flow process, and further improving the sound attenuation.

[0085] It is worth noting that at least one silencer channel is connected to the air inlet 120, and at least one silencer channel is connected to the air outlet 130. It is understandable that each of the multiple silencer channels is connected to the air inlet 120 and the air outlet 130. Alternatively, the multiple silencer channels include a first silencer channel, a second silencer channel, and multiple third silencer channels, wherein the first silencer channel is connected to the air inlet 120, the second silencer channel is connected to the air outlet 130, and the multiple third silencer channels are connected to each other and are respectively connected to the first silencer channel and the second silencer channel. Specific settings can be made according to actual needs.

[0086] like Figure 1 and Figure 2 As shown, based on the above embodiment, the baffle assembly 140 further includes a first baffle 141, which is arranged close to the air inlet 120 and inserted into the muffler cavity 111 along the air inlet direction of the air inlet 120.

[0087] In this embodiment, it is defined that the baffle assembly 140 includes a first baffle 141. Specifically, the first baffle 141 is arranged near the air inlet 120, that is, the silencer channel begins to be separated near the air inlet 120, that is, the silencer channel is arranged near the air inlet 120, so that the silencer can start as soon as the air flow enters the air inlet 120, further extending the flow time of the air flow in the silencer chamber 111, increasing the number of reflections of the sound waves in multiple silencer channels, and improving the silencer effect.

[0088] Along the air intake direction of the air flow at the air inlet 120, the first baffle 141 is inserted into the silencer chamber 111, that is, the first end of the first baffle 141 is arranged close to the air inlet 120, and the second end of the first baffle 141 extends into the silencer chamber 111 along the axial direction of the air inlet 120, so that the flow path of the air flow in the silencer chamber 111 can be changed multiple times without increasing the air flow resistance, and the flow time of the air flow in the silencer chamber 111 can be extended, so that the sound waves are offset by multiple reflections and interferences in multiple silencer channels, thereby improving the silencer effect of the air flow flowing through the silencer 100, and can significantly improve the transmission loss of the medium and high frequencies of the compressor 200 in which the silencer 100 is arranged between the air intake 211 and the opening 224 of the stator 221, thereby improving the silencer volume of the entire compressor 200.

[0089] It can be understood that there is a preset distance between the inner wall of the shell 110 opposite to the air inlet 120 and the second end of the first baffle 141, that is, along the insertion direction of the first baffle 141, the insertion depth of the first baffle 141 cannot be too deep, so that the noise reduction effect of the airflow flowing through the muffler 100 can be improved without increasing the flow resistance of the airflow.

[0090] Alternatively, the first baffle 141 and the inner side wall of the shell 110 opposite to the air inlet 120 are in contact, and a connecting hole is opened on the first baffle 141, which is connected to the air inlet 120 and multiple silencer channels, thereby improving the noise reduction effect of the airflow flowing through the silencer 100 without increasing the flow resistance of the airflow.

[0091] like Figure 1 and Figure 2 As shown, on the basis of the above embodiment, further, the first end of the first baffle 141 is arranged at the air inlet 120, and the air inlet 120 is divided into at least two sub-air inlets 121, and the at least two sub-air inlets 121 are respectively connected to multiple silencer channels, and the second end of the first baffle 141 is inserted into the silencer chamber 111.

[0092] In this embodiment, the first end of the first baffle 141 is located at the air inlet 120, and the first baffle 141 divides the air inlet 120 into at least two sub-air inlets 121, and at least two sub-air inlets 121 are respectively connected to multiple silencer channels, and the second end of the first baffle 141 is inserted into the silencer cavity 111, that is, at least one silencer channel extends to the air inlet 120, which is beneficial to extend the airflow path while increasing the length of the silencer channel, thereby increasing the flow time of the airflow in multiple silencer channels, and then increasing the number of reflections of sound waves in the silencer pipeline, thereby improving the silencer effect.

[0093] Along the air intake direction of the air flow at the air inlet 120, the first baffle 141 is inserted into the silencer chamber 111, that is, the first end of the first baffle 141 is located at the air inlet 120, and the second end of the first baffle 141 extends into the silencer chamber 111 along the axial direction of the air inlet 120, so that the flow path of the air flow in the silencer chamber 111 can be changed multiple times without increasing the air flow resistance, and the flow time of the air flow in the silencer chamber 111 can be extended, so that the sound waves are offset by multiple reflections and interferences in multiple silencer channels, thereby improving the silencer effect of the air flow flowing through the silencer 100, and can significantly improve the transmission loss of the medium and high frequencies of the compressor 200 in which the silencer 100 is set between the air intake 211 and the opening 224 of the stator 221, thereby improving the silencer volume of the entire compressor 200.

[0094] like Figure 1 As shown, on the basis of the above embodiment, further, the shell 110 includes a first plate body 112 and a second plate body 113 arranged opposite to each other, the air inlet 120 is provided on the first plate body 112, and the air outlet 130 is provided on the second plate body 113; along the direction from the first plate body 112 to the second plate body 113, the distance H between the inner side wall of the first plate body 112 and the inner side wall of the second plate body 113 and the height h of the first baffle 141 satisfy h>H / 2.

[0095] In this embodiment, the housing 110 includes a first plate 112 and a second plate 113, wherein the first plate 112 and the second plate 113 are disposed opposite each other, the air inlet 120 is disposed on the first plate 112, and the air outlet 130 is disposed on the second plate 113. Since the first end of the first baffle 141 is located at the air inlet 120, that is, at least one muffler channel extends to the air inlet 120, arranging the air inlet 120 and the air outlet 130 on two opposing plates of the housing 110, respectively, further extends the flow path of the airflow within the muffler 100, increases the flow time of the airflow within the muffler 100, and thereby improves the muffler effect.

[0096] The height of the first baffle 141 is greater than half the distance between the inner sidewalls of the first plate body 112 and the inner sidewalls of the second plate body 113. This limits the insertion depth of the first baffle 141 from the air inlet 120 to the muffler chamber 111. This improves the muffler's 100 muffler performance without increasing airflow resistance.

[0097] Moreover, the height of the first baffle 141 is greater than 1 / 2 of the distance between the inner wall of the first plate body 112 and the inner wall of the second plate body 113, that is, the distance between the second end of the first baffle 141 and the inner wall of the second plate body 113 is smaller, so that a cross-sectional mutation can be generated when the air flow flows through here, thereby changing the flow path of the air flow, so that the sound waves can be reflected and interfered in multiple silencer channels and offset, thereby improving the noise reduction effect of the silencer 100.

[0098] like Figure 1 As shown, on the basis of the above embodiment, the shell 110 further includes a third plate 114 and a fourth plate 114 arranged relatively to each other, the third plate 114 is connected to the first plate 112 and the second plate 113, and the fourth plate is connected to the first plate 112 and the second plate 113; the first baffle 141 is connected to the third plate 114 and / or the fourth plate.

[0099] In this embodiment, the housing 110 further includes a third plate 114 and a fourth plate. Specifically, the third plate 114 and the fourth plate are disposed opposite each other, and the third plate 114 is connected to the first plate 112 and the second plate 113, while the fourth plate is connected to the first plate 112 and the second plate 113. Thus, the first plate 112, the second plate 113, the third plate 114, and the fourth plate enclose a muffler chamber 111.

[0100] The first baffle 141 is connected to the third plate 114, thereby improving the structural stability and stiffness of the first baffle 141, preventing the first baffle 141 from vibrating due to the impact of airflow when flowing within the muffler chamber 111, thereby causing secondary noise. This further improves the muffler effect of the muffler 100 and thereby reduces the suction noise of the compressor 200 equipped with the muffler 100.

[0101] The first baffle 141 is connected to the fourth plate, thereby further improving the structural stability of the first baffle 141 and further increasing the rigidity of the first baffle 141, thereby preventing the first baffle 141 from vibrating due to the impact of the airflow when flowing in the muffler chamber 111, thereby causing secondary noise. This further improves the muffler effect of the muffler 100 and thereby reduces the suction noise of the compressor 200 equipped with the muffler 100.

[0102] like Figure 1 and Figure 2 As shown, based on the above embodiment, further, along the direction from the first plate body 112 to the second plate body 113 , the air outlet 130 and the air inlet 120 are staggered.

[0103] In this embodiment, the air outlet 130 and the air inlet 120 are staggered along the direction from the first plate body 112 to the second plate body 113. Since one end of the first baffle 141 is located at the air inlet 120, that is, the silencer channel extends to the air inlet 120. By staggering the air inlet 120 and the air outlet 130, it is beneficial to extend the air flow path while increasing the length of the silencer channel, thereby increasing the flow time of the air flow in multiple silencer channels, and then increasing the number of reflections of the sound waves in the silencer pipe, thereby improving the silencer effect.

[0104] It can be understood that the baffle assembly 140 also includes a second baffle 142, and the second baffle 142 includes a first baffle 1421. The first baffle 1421 is arranged close to the air outlet 130. Since the air outlet 130 and the air inlet 120 are staggered, the length of the silencer channel can be further increased, thereby increasing the number of reflections of the sound waves in the silencer pipeline, and further improving the silencer effect.

[0105] like Figure 1 and Figure 6 As shown, on the basis of any of the above embodiments, further, the baffle assembly 140 also includes a second baffle 142, the second baffle 142 includes a first baffle 1421, the first baffle 1421 is arranged near the air outlet 130, and along the air outlet direction of the air outlet 130, the first baffle 1421 is inserted into the silencer chamber 111.

[0106] In this embodiment, it is defined that the baffle assembly 140 also includes a second baffle 142. Specifically, the second baffle 142 includes a first baffle 1421, which is arranged near the air outlet 130 and is inserted into the silencer cavity 111 along the air outlet direction of the air flow at the air outlet 130. That is, along the direction from the first plate body 112 to the second plate body 113, the first end of the first baffle 1421 is arranged near the air outlet 130, and the second end of the first baffle 1421 is inserted into the silencer cavity 111, that is, at least one silencer channel extends to a position near the air outlet 130, which is beneficial to extend the air flow path while increasing the length of the silencer channel, thereby increasing the flow time of the air flow in multiple silencer channels, and then increasing the number of reflections of sound waves in the silencer pipeline, thereby improving the silencer effect.

[0107] Moreover, the first baffle 1421 is arranged close to the air outlet 130, so that the flow path of the airflow in the silencer chamber 111 can be changed multiple times without increasing the airflow resistance, thereby extending the flow time of the airflow in the silencer chamber 111, and thus making the sound waves cancel each other out after multiple reflections and interferences in multiple silencer channels, thereby improving the silencer effect of the airflow flowing through the silencer 100, and can significantly improve the transmission loss of the medium and high frequencies of the compressor 200 in which the silencer 100 is arranged between the air intake 211 and the opening 224 of the stator 221, thereby improving the silencer volume of the entire compressor 200.

[0108] like Figure 1 As shown, on the basis of any of the above embodiments, further, the first end of the first stop portion 1421 is located at the air outlet 130, and the air outlet 130 is divided into at least two sub-air outlets 131, at least two sub-air outlets 131 are connected to multiple silencer channels, and the second end of the first stop portion 1421 is inserted into the silencer chamber 111.

[0109] In this embodiment, the first end of the first stop 1421 is located at the air outlet 130, and the first stop 1421 divides the air outlet 130 into at least two sub-air outlets 131, and at least two sub-air outlets 131 are respectively connected to multiple silencer channels, and the second end of the first stop 1421 is inserted into the silencer cavity 111, that is, at least one silencer channel extends to the air outlet 130, which is beneficial to extend the airflow path while further increasing the length of the silencer channel, thereby increasing the flow time of the airflow in multiple silencer channels, and then increasing the number of reflections of sound waves in the silencer pipeline, thereby improving the silencer effect.

[0110] like Figure 1 and Figure 6 As shown, on the basis of any of the above embodiments, further, the second baffle 142 also includes a second baffle 1422, the second baffle 1422 is connected to the first baffle 1421, and forms a preset angle with the first baffle 1421, and the second baffle 1422 extends from one end of the first baffle 1421 toward the side where the air inlet 120 is located.

[0111] In this embodiment, the second baffle 142 further includes a second stop portion 1422. Specifically, the second stop portion 1422 is connected to the first stop portion 1421, and a preset angle is formed between the second stop portion 1422 and the first stop portion 1421. For example, the preset angle may be 90 degrees. In other words, the second baffle 142 is a corner plate.

[0112] The end of the second stop 1422 away from the first stop 1421 extends toward the air inlet 120, that is, the end of the second stop 1422 away from the first stop 1421 extends toward the side where the first baffle 141 is located. This divides the muffler chamber 111 into multiple muffler channels. That is, the first baffle 141 and the second baffle 142 divide the muffler chamber 111 with a larger volume into multiple interconnected muffler channels with smaller volumes. After the airflow flows into the muffler channels with smaller volumes, the sound waves can be offset by multiple reflections and interferences in the muffler channels with smaller volumes. Moreover, after the airflow is muffled in one muffler channel with smaller volumes, it can flow through the remaining muffler channels for further muffler elimination, thereby achieving the purpose of noise reduction.

[0113] The silencer chamber 111 is divided into a plurality of silencer channels by the first baffle 141 and the second baffle 142, so that after the airflow enters from the air inlet 120, it can change the flow path of the airflow in the silencer chamber 111 multiple times without increasing the flow resistance of the airflow, thereby extending the flow time of the airflow in the silencer chamber 111, and thus making the sound waves cancel out after multiple reflections and interferences in the multiple silencer channels, thereby improving the silencer effect of the airflow flowing through the silencer 100, and can significantly improve the transmission loss of the medium and high frequencies of the compressor 200 in which the silencer 100 is set between the air intake 211 and the opening 224 of the stator 221, thereby improving the silencer volume of the entire compressor 200.

[0114] In actual application, the muffler 100 is disposed between the air intake 211 of the compressor 200 and the opening 224 of the stator 221. Specifically, the air intake 120 is connected to the air intake 211, and the opening 224 is connected to the air outlet 130. During the air intake process of the compressor 200, the air flows into the air intake 120 through the air intake 211, flows out to the air outlet 130 through multiple muffler channels, and enters the compression chamber 223 through the opening 224 of the stator 221. By providing the baffle assembly 140 within the muffler chamber 111, the number of reflections of the airflow within the multiple muffler channels can be increased, the flow time of the airflow within the muffler chamber 111 can be extended, and the noise reduction effect during the air intake process of the compressor 200 can be improved.

[0115] In practical applications, the extension length of the second stop portion 1422 can be adjusted according to the noise reduction frequency required by the compressor 200 .

[0116] In a specific embodiment, further, the housing 110 is a plastic housing 110; and / or the baffle assembly 140 is a plastic baffle.

[0117] In this embodiment, the shell 110 is a plastic shell 110 , which facilitates the processing of the shell 110 and can further reduce the production cost of the muffler 100 .

[0118] The baffle assembly 140 is a plastic baffle, which facilitates the processing of the baffle assembly 140 and can further reduce the production cost of the muffler 100 .

[0119] Furthermore, the housing 110 and the baffle assembly 140 may be an integrated structure. As will be appreciated, an integrated structure exhibits superior mechanical properties, thereby further improving the stability of the connection between the baffle assembly 140 and the housing 110 and preventing vibration of the baffle assembly 140 due to the impact of airflow when flowing within the muffler chamber 111, thereby causing secondary noise. Furthermore, the integrated structure facilitates the processing and production of the muffler 100, thereby reducing the production cost of the muffler 100.

[0120] According to a second aspect of the present invention, a compressor 200 is provided, comprising the muffler 100 provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the muffler 100, which will not be described in detail here.

[0121] like Figure 5 and Figure 6 As shown, further, the compressor 200 also includes a shell 210, a compression assembly 220 and a driving member 230, wherein the shell 210 is provided with an air intake port 211, the air intake port 211 is connected to the air inlet 120, the compression assembly 220 is arranged in the shell 210, the compression assembly 220 includes a stator 221 and a movable plate 222, the stator 221 and the movable plate 222 are enclosed to form a compression chamber 223, the stator 221 is provided with an opening 224, the opening 224 is connected to the compression chamber 223 and the air outlet 130, and the driving member 230 is connected to the movable plate 222.

[0122] The compressor 200 provided in the embodiment of the present invention includes a muffler 100, a housing 210, a compression assembly 220 and a driving member 230. Specifically, the compression assembly 220 includes a stator 221 and a rotor 222. The stator 221 and the rotor 222 enclose a compression chamber 223. The stator 221 is provided with an opening 224 connected to the compression chamber 223. The opening 224 is connected to the air outlet 130 of the muffler 100. The housing 210 is provided with an air intake 211. The air intake 211 is connected to the air inlet 120 of the muffler 100. When the compressor 200 inhales air, the air flow enters the air inlet 120 through the air intake 211, and after being silenced by multiple muffler channels, it is discharged from the air outlet 130 to the opening 224 and enters the compression chamber 223 through the opening 224. The driving member 230 drives the moving plate 222 to rotate relative to the stator plate 221 to compress the gas in the compression chamber 223 . The compressed high-temperature and high-pressure gas is discharged through the exhaust port of the stator plate 221 .

[0123] It can be understood that the driving member 230 includes a motor and a crankshaft, the motor is connected to the crankshaft, and the crankshaft is connected to the moving plate 222.

[0124] Baffle assembly 140 is disposed within muffler chamber 111 and divides muffler chamber 111 into multiple muffler channels, each of which is interconnected. At least one muffler channel is connected to air inlet 120, and at least one muffler channel is connected to air outlet 130. In other words, air enters through air inlet 120, flows through the multiple muffler channels, and is discharged from air outlet 130.

[0125] Among them, the baffle assembly 140 divides the silencer chamber 111 into multiple silencer channels, that is, the baffle assembly 140 divides the silencer chamber 111 with a larger volume into multiple silencer channels with smaller volumes that are interconnected. After the airflow flows into the silencer channel with a smaller volume, the sound waves can be offset by multiple reflections and interferences in the silencer channel with a smaller volume. After the airflow is silenced by a silencer channel with a smaller volume, it can also flow through the remaining silencer channels for further silencing, thereby achieving the purpose of noise reduction.

[0126] That is to say, by setting the baffle assembly 140, the silencer chamber 111 is divided into multiple silencer channels, so that after the airflow enters from the air inlet 120, it can change the flow path of the airflow in the silencer chamber 111 multiple times without increasing the airflow resistance, thereby extending the flow time of the airflow in the silencer chamber 111, and thus making the sound waves offset after multiple reflections and interferences in the multiple silencer channels, thereby improving the silencer effect of the airflow flowing through the silencer 100, and can significantly improve the transmission loss of the medium and high frequencies of the compressor 200 in which the silencer 100 is set between the air intake 211 and the opening 224 of the stator 221, thereby improving the silencer volume of the entire compressor 200.

[0127] The muffler 100 is disposed between the intake port 211 of the compressor 200 and the opening 224 of the stator 221. Specifically, the intake port 120 is connected to the intake port 211, and the opening 224 is connected to the outlet 130. During the intake process of the compressor 200, air flows into the intake port 120 through the intake port 211, flows out to the outlet 130 through multiple muffler channels, and enters the compression chamber 223 through the opening 224 of the stator 221. By providing the baffle assembly 140 within the muffler chamber 111, the number of airflow reflections within the multiple muffler channels can be increased, the airflow flow time within the muffler chamber 111 can be extended, and the noise reduction effect during the intake process of the compressor 200 can be improved.

[0128] In addition, the first part of the baffle assembly 140 is arranged close to the air inlet 120, that is, the silencer channel is arranged close to the air inlet 120, so that the silencer can start as soon as the air flow enters the air inlet 120, further extending the flow time of the air flow in the silencer chamber 111, increasing the number of reflections of the sound waves in multiple silencer channels, and improving the silencer effect.

[0129] The second part of the baffle assembly 140 is arranged close to the air outlet 130, so that the air flow can be silenced again in the process of flowing out through the air outlet 130, further extending the flow time of the air flow in the silencer chamber 111, increasing the number of reflections of the sound waves during the flow process, and further improving the sound attenuation.

[0130] like Figure 5 and Figure 6 As shown, based on the above embodiment, further, the flow cross-sectional area of the air intake port 211 is equal to the flow cross-sectional area of the air inlet 120 .

[0131] In this embodiment, the flow cross-sectional area of the suction port 211 is equal to the flow cross-sectional area of the air inlet 120, thereby ensuring the suction efficiency of the compressor 200. It is understood that if the flow cross-sectional area of the air inlet 120 is larger than the flow cross-sectional area of the suction port 211, the gas in the casing 110 is likely to flow into the air inlet 120 during the suction process of the compressor 200, affecting the operation of the compressor 200.

[0132] If the flow cross-sectional area of the air inlet 120 is smaller than the flow cross-sectional area of the air suction port 211 , the flow resistance of the gas will increase, thereby reducing the suction efficiency of the compressor 200 .

[0133] like Figure 5 and Figure 6 As shown, based on the above embodiment, the housing 110 is further provided with a relief opening 150 , which is communicated with the air outlet 130 , and a portion of the stator 221 is located in the relief opening 150 and abuts against the housing 110 .

[0134] In this embodiment, the housing 110 is provided with a relief opening 150, which communicates with the air outlet 130. Specifically, a portion of the stator plate 221 is located within the relief opening 150 and abuts the housing 110. The provision of the relief opening 150 prevents interference with the structure of the stator plate 221 during installation of the muffler 100 and the compressor 200. Furthermore, the abutment of the portion of the stator plate 221 against the housing 110 improves the structural stability of the muffler 100.

[0135] In actual application, the housing 110 is further provided with a mounting portion, and the mounting portion is provided with a mounting hole, and the housing 110 is mounted and fixed to the static plate 221 through the mounting hole.

[0136] According to a third aspect of the present invention, an air conditioner is provided, comprising the compressor 200 provided in any of the above embodiments, thereby having all the beneficial technical effects of the compressor 200, which will not be described in detail here.

[0137] In practical applications, the compressor 200 defined in this application includes but is not limited to a scroll compressor.

[0138] In this specification, the terms "connect," "install," and "fix" should be understood broadly. For example, "connect" can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediary.
