Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically, to a compressor and a refrigerator. Background Technology

[0002] Reciprocating compressors used in refrigerators typically draw gas in through the suction pipe in the casing, buffer it in the back pressure chamber, and then it enters the suction muffler. This flow channel structure affects the compressor's suction efficiency. For example, the compatibility between components and the temperature of the back pressure chamber can all have an adverse effect on the suction volume and suction temperature, thereby affecting the compressor's cooling capacity and cooling performance. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of the above, in a first aspect, this utility model proposes a compressor, comprising: a housing, the housing having an installation port; an intake silencer located inside the housing, the intake silencer having a silencer inlet and an intake channel, the intake channel communicating with the silencer inlet and being located inside the intake silencer; an intake pipe located outside the housing, one end of the intake pipe being connected to the housing; and a flexible sleeve, the first end of the flexible sleeve being connected to the intake pipe, a portion of the flexible sleeve passing through the installation port and extending into the housing, the second end of the flexible sleeve being oriented towards the silencer inlet, and the intake pipe communicating with the silencer inlet through the flexible sleeve.

[0005] Low-temperature, low-pressure gas flows into the housing through the intake pipe. After performing work on the gas, the high-temperature, high-pressure gas is discharged outwards. An intake silencer is installed inside the housing. The gas flowing into the housing through the intake pipe first flows to the intake silencer. The intake silencer can effectively absorb and attenuate the noise generated during gas flow, and it can also buffer the intake gas, improving its stability.

[0006] During compressor operation, the intake muffler will experience a certain degree of shaking and vibration. Since the housing and intake pipe are usually supported by metal materials, if the intake muffler is placed close to the housing or intake pipe, it will collide with the housing or intake pipe, generating significant noise and potentially damaging the muffler. If the intake muffler is fixed to the housing or intake pipe, it risks falling off due to the shaking and vibration. Furthermore, if the intake muffler is spaced apart from the intake pipe, the gas flowing between the intake pipe and the intake muffler during intake will be affected by the internal temperature of the housing, causing the gas temperature to rise.

[0007] In this design, a flexible sleeve is installed on the intake pipe. The flexible sleeve passes through the mounting port on the housing, so the first end of the flexible sleeve is located outside the housing and the second end is located inside the housing. The first end of the flexible sleeve is connected to the intake pipe, so the intake pipe does not need to extend into the housing, which facilitates welding the intake pipe to the housing. The second end of the flexible sleeve is connected to the intake silencer inside the housing. Therefore, the intake pipe is connected to the intake silencer through the flexible sleeve, allowing the gas in the intake pipe to flow to the intake silencer through the flexible sleeve.

[0008] The flexible sleeve connects to the silencer inlet of the suction muffler. Because the flexible sleeve is relatively soft, even if the suction muffler impacts it, it is unlikely to generate noise, thus reducing the noise level during compressor operation. Furthermore, by installing the flexible sleeve between the suction pipe and the suction muffler, even with a large gap between them, the intake gas is less susceptible to temperature fluctuations within the casing, preventing overheating and avoiding adverse effects on the compressor's suction volume and temperature. This ultimately improves the compressor's cooling capacity and performance.

[0009] In this design, the air intake channel of the intake muffler is recessed within the muffler's housing, saving space occupied by external pipes. This allows for a larger intake muffler to be installed within a limited space, increasing the housing space and thus improving the muffler's noise reduction effect.

[0010] In some technical solutions, the flexible sleeve may optionally include a sleeve body and a buffer section, with the second end of the flexible sleeve attached to the intake muffler, and the buffer section distributed circumferentially along the sleeve body.

[0011] The sleeve body fits into the intake muffler, so there is no gap between the flexible sleeve and the intake muffler. This ensures that the intake air does not easily leak into the housing and also avoids the temperature inside the housing affecting the intake air. Moreover, because the sleeve body is relatively soft, it can fit tightly into the intake muffler, ensuring a good seal between the flexible sleeve and the intake muffler.

[0012] A buffer section is provided on the casing body. When the casing body shakes, the buffer section can cushion the casing body. Since the casing body is attached to the intake muffler in this solution, when the compressor is running, the intake muffler will cause the casing body to shake or vibrate. By cushioning the casing body with the buffer section, the casing body can be prevented from breaking or being damaged, thereby reducing the damage rate of the casing body.

[0013] In some technical solutions, optionally, the buffer portion protrudes from the sleeve body in a direction away from the center of the sleeve body, and the housing and the intake silencer are spaced apart from the buffer portion.

[0014] The buffer section protrudes from the surface of the sleeve body. This design allows the buffer section to deform more easily. When the sleeve body shakes or vibrates, the buffer section can improve the cushioning effect on the sleeve body, thereby further reducing the damage rate of the flexible sleeve.

[0015] In this design, the buffer section is located between the housing and the intake silencer, and the buffer section does not contact the housing or the intake silencer. In the event of deformation of the buffer section, the housing and the intake silencer will not obstruct the buffer section, thereby ensuring that the buffer section can stably deform and thus stably buffer the casing body.

[0016] In some technical solutions, optionally, a gap is left between the second end of the flexible sleeve and the intake muffler, and the distance between the flexible sleeve and the intake muffler is L, where 0mm < L ≤ 3mm.

[0017] In this design, the second end of the flexible sleeve does not contact the intake muffler. That is, the second end of the flexible sleeve is spaced apart from the intake muffler. When the intake muffler shakes or vibrates, it is not easy for the intake muffler to contact the flexible sleeve. Even if it does contact the flexible sleeve, the intake muffler will not cause the flexible sleeve to shake significantly.

[0018] In this design, the distance between the flexible sleeve and the intake muffler is limited to less than or equal to 3mm. Therefore, a small gap is left between the flexible sleeve and the intake muffler, making it less likely for gas flowing to the intake muffler to leak, and the gas is also less affected by the internal temperature of the housing. Thus, within this distance range, the shaking effect of the intake muffler on the flexible sleeve can be reduced, and gas leakage and intake overheating can also be avoided.

[0019] With the flexible sleeve and the intake muffler spaced apart, the buffer section on the flexible sleeve can be eliminated. The gap between the intake muffler and the flexible sleeve can buffer the intake muffler. Even if the intake muffler touches the flexible sleeve, the flexible sleeve will only shake slightly. Therefore, by eliminating the buffer section, the processing difficulty of the flexible sleeve can be reduced.

[0020] The flexible sleeve is relatively soft and is not prone to generating noise when touched by the intake muffler.

[0021] In some technical solutions, optionally, the wall thickness of the flexible sleeve is W, where W≤1mm.

[0022] The greater the thickness of the flexible sleeve, the less prone it is to deformation. However, if the flexible sleeve is in close contact with the intake muffler, misalignment can easily occur between them as the muffler moves, resulting in a large gap. If this gap exists, the flexible sleeve is more likely to make a sound when it touches the intake muffler.

[0023] This design specifies that the wall thickness of the flexible sleeve is less than or equal to 1 mm. Within this range, if the flexible sleeve is in contact with the intake muffler, its small wall thickness allows for easy deformation, ensuring a stable fit. If a gap exists between the flexible sleeve and the intake muffler, even if the sleeve is touched by the muffler, it is less likely to produce noise, thus reducing compressor operating noise.

[0024] In some technical solutions, optionally, a portion of the flexible sleeve located inside the housing is provided with a connecting hole, and the flexible sleeve and the interior of the housing are connected through the connecting hole.

[0025] A connecting hole is machined into the flexible sleeve, which connects the inside of the housing and the inside of the flexible sleeve, so that the air pressure between the inside of the housing and the flexible sleeve is balanced, which helps to improve the stability of the compressor intake process.

[0026] In some technical solutions, the second end of the flexible sleeve is optionally flared, and the opening area of ​​the second end of the flexible sleeve is larger than the opening area of ​​the silencing inlet, and the second end of the flexible sleeve covers the silencing inlet.

[0027] The flexible sleeve is flared on the side facing the intake muffler, which allows the end of the flexible sleeve to completely cover the muffler inlet, preventing air leakage between the flexible sleeve and the intake muffler, and also preventing the temperature inside the housing from affecting the intake air.

[0028] By setting the end of the flexible sleeve to be flared, the radial dimensions of other parts of the flexible sleeve can be set to be smaller, thereby avoiding the flexible sleeve occupying too much space inside the housing.

[0029] In some technical solutions, the flexible sleeve may optionally be a fluororubber suction tube.

[0030] Fluororubber gives flexible bushings good chemical stability, strong corrosion resistance and good compatibility. Fluororubber is not easy to react chemically with refrigerants and is not easily corroded, thus ensuring the structural stability of the flexible bushing. Moreover, when fluorides are used as refrigerants, fluororubber has good compatibility with refrigerants. When the two come into contact, they are not likely to interact and produce substances that are detrimental to the operation of the system, thus ensuring the stability and reliability of the system.

[0031] In some technical solutions, the outer surface of the flexible sleeve is optionally provided with a protrusion, the protrusion is located outside the shell, the circumferential direction of the suction pipe is provided with a receiving groove, the protrusion extends into the receiving groove, and the protrusion is located between the suction pipe and the shell.

[0032] The intake tube has a circumferentially shaped receiving groove, and the outer surface of the flexible sleeve has a protrusion. The protrusion can be embedded into the receiving groove. Moreover, the protrusion is located between the intake tube and the shell. The intake tube and the shell limit the protrusion, so the flexible sleeve is not easy to move relative to the intake tube and the shell, thereby avoiding separation of the flexible sleeve and the intake tube and ensuring the connection stability of the flexible sleeve and the intake tube.

[0033] Secondly, this utility model proposes a refrigerator, including the compressor as described in the first aspect.

[0044] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model 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.

[0045] Many specific details are set forth in the following description in order to provide 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.

[0046] The following reference Figures 1 to 6 This invention describes a compressor and a refrigerator provided according to some embodiments of the present invention.

[0047] Combination Figure 1 and Figure 2 As shown, in some embodiments of this utility model, a compressor 100 is proposed. The compressor 100 includes: a housing 110, an intake silencer 120, an intake pipe 130, and a flexible sleeve 140. The housing 110 is provided with an installation port 111. The intake silencer 120 is located inside the housing 110 and is provided with a silencer inlet 121 and an intake channel 122. The intake channel 122 communicates with the silencer inlet 121 and is located inside the intake silencer 120. The intake pipe 130 is disposed outside the housing 110, and one end of the intake pipe 130 is connected to the housing 110. The first end of the flexible sleeve 140 is connected to the intake pipe 130. A portion of the flexible sleeve 140 passes through the installation port 111 and extends into the housing 110. The second end of the flexible sleeve 140 is positioned facing the silencer inlet 121. The intake pipe 130 communicates with the silencer inlet 121 through the flexible sleeve 140.

[0048] Low-temperature, low-pressure gas flows into the housing 110 through the intake pipe 130. After performing work on the gas, the high-temperature, high-pressure gas is discharged outwards. An intake silencer 120 is installed inside the housing 110. The gas flowing into the housing 110 through the intake pipe 130 first flows to the intake silencer 120. The intake silencer 120 can effectively absorb and attenuate the noise generated during gas flow, and it can also buffer the intake gas, improving its stability.

[0049] During the operation of the compressor 100, the intake muffler 120 will experience a certain degree of shaking and vibration. Since the housing 110 and the intake pipe 130 are typically supported by metal materials, if the intake muffler 120 is placed close to the housing 110 or the intake pipe 130, the intake muffler 120 will collide with the housing 110 or the intake pipe 130, generating significant noise and potentially damaging the intake muffler 120. If the intake muffler 120 is fixed to the housing 110 or the intake pipe 130, there is a risk that it may fall off due to the shaking and vibration. Furthermore, if the intake muffler 120 and the intake pipe 130 are spaced apart, during the intake process, the gas flowing between the intake pipe 130 and the intake muffler 120 will be affected by the internal temperature of the housing 110, causing the gas temperature to rise.

[0050] In this design, a flexible sleeve 140 is installed on the intake pipe 130. The flexible sleeve 140 passes through the mounting port 111 on the housing 110. Therefore, the first end of the flexible sleeve 140 is located outside the housing 110, and the second end is located inside the housing 110. The first end of the flexible sleeve 140 is connected to the intake pipe 130, so the intake pipe 130 does not need to extend into the housing 110, so that the intake pipe 130 can be welded to the housing 110. The second end of the flexible sleeve 140 is connected to the intake silencer 120 inside the housing 110. Therefore, the intake pipe 130 is connected to the intake silencer 120 through the flexible sleeve 140, so that the gas in the intake pipe 130 can flow to the intake silencer 120 through the flexible sleeve 140.

[0051] The flexible sleeve 140 is connected to the silencer inlet 121 of the suction silencer 120. Because the flexible sleeve 140 is relatively soft, even if the suction silencer 120 impacts the flexible sleeve 140, it is unlikely to generate noise, thus reducing the noise during compressor 100 operation. Furthermore, by providing the flexible sleeve 140 between the suction pipe 130 and the suction silencer 120, even with a large gap between them, the intake gas is less likely to be affected by the internal temperature of the casing 110, preventing overheating during suction and avoiding adverse effects on the suction volume and temperature of the compressor 100. This helps improve the cooling capacity and performance of the compressor 100.

[0052] In this design, the air intake channel 122 of the intake muffler 120 is recessed within the housing cavity of the intake muffler, saving the space occupied by the external pipes of the intake muffler 120. This allows for a larger intake muffler 120 to be installed in a limited space. This arrangement increases the housing cavity space of the intake muffler 120, thereby improving the noise reduction effect of the intake muffler 120.

[0053] The suction structure in this embodiment can significantly improve the adverse effects of the suction process of the reciprocating compressor 100, reducing suction flow resistance, pressure drop, and heating effects. The compressor 100 using the above-described suction structure can improve its performance and energy efficiency, better meeting the high energy efficiency requirements of refrigerators, and has high practical value.

[0054] In this embodiment, the silencing inlet 121 is flush with the outer surface of the intake silencer 120, that is, the outer surface of the intake silencer 120 is not provided with a pipe structure for air intake, thereby saving the space occupied by the intake pipe structure.

[0055] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the flexible sleeve 140 includes a sleeve body 141 and a buffer portion 142, the second end of the flexible sleeve 140 is attached to the intake muffler 120, and the buffer portion 142 is circumferentially aligned with the sleeve body 141. Figure 3 The arrow at point C points to the distribution.

[0056] The sleeve body 141 is attached to the intake muffler 120, so there is no gap between the flexible sleeve 140 and the intake muffler 120. This ensures that the intake air is not easily leaked into the housing 110 and also avoids the temperature inside the housing 110 from affecting the intake air. Moreover, because the sleeve body 141 is relatively soft, it can fit tightly against the intake muffler 120, ensuring a good seal between the flexible sleeve 140 and the intake muffler 120.

[0057] A buffer section 142 is provided on the sleeve body 141. When the sleeve body 141 shakes, the buffer section 142 can buffer the sleeve body 141. Since the sleeve body 141 is attached to the intake silencer 120 in this solution, when the compressor 100 is running, the intake silencer 120 will cause the sleeve body 141 to shake or vibrate. By buffering the sleeve body 141 through the buffer section 142, the sleeve body 141 can be prevented from breaking or being damaged, thereby reducing the damage rate of the sleeve body 141.

[0058] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the buffer portion 142 protrudes from the sleeve body 141 in a direction away from the center of the sleeve body 141, and the housing 110 and the intake silencer 120 are both spaced apart from the buffer portion 142.

[0059] The buffer portion 142 protrudes from the surface of the sleeve body 141. This arrangement makes the buffer portion 142 more easily deformable. When the sleeve body 141 shakes or vibrates, the buffer portion 142 can improve the buffering effect on the sleeve body 141, thereby further reducing the damage rate of the flexible sleeve 140.

[0060] In this design, the buffer section 142 is located between the housing 110 and the intake silencer 120, and the buffer section 142 does not contact the housing 110 and the intake silencer 120. When the buffer section 142 deforms, the housing 110 and the intake silencer 120 will not obstruct the buffer section 142, thereby ensuring that the buffer section 142 can stably deform and thus stably buffer the sleeve body 141.

[0061] like Figure 2 As shown, in some embodiments, optionally, a gap is left between the second end of the flexible sleeve 140 and the intake muffler 120, and the distance between the flexible sleeve 140 and the intake muffler 120 is L, 0mm < L ≤ 3mm.

[0062] In this design, the second end of the flexible sleeve 140 does not contact the intake muffler 120. That is, the second end of the flexible sleeve 140 is spaced apart from the intake muffler 120. When the intake muffler 120 shakes or vibrates, the intake muffler 120 is unlikely to contact the flexible sleeve 140. Even if it does contact the flexible sleeve 140, the intake muffler 120 will not cause the flexible sleeve 140 to shake significantly.

[0063] In this design, the distance between the flexible sleeve 140 and the intake muffler 120 is limited to less than or equal to 3 mm. Therefore, a small gap is left between the flexible sleeve 140 and the intake muffler 120, making it less likely for the gas flowing to the intake muffler to leak. The gas is also less likely to be affected by the internal temperature of the housing 110. Thus, within this distance range, the shaking effect of the intake muffler 120 on the flexible sleeve 140 can be reduced, and gas leakage and overheating of the intake can also be avoided.

[0064] When the flexible sleeve 140 and the intake muffler 120 are spaced apart, the buffer part 142 on the flexible sleeve 140 can be eliminated. The gap between the intake muffler 120 and the flexible sleeve 140 can buffer the intake muffler 120. Even if the intake muffler 120 touches the flexible sleeve 140, the flexible sleeve 140 will only shake slightly. Therefore, by eliminating the buffer part 142, the processing difficulty of the flexible sleeve 140 can be reduced.

[0065] The flexible sleeve 140 is relatively soft and is not prone to generating noise when touched by the intake muffler 120.

[0066] Combination Figure 3 and Figure 4 As shown, in some embodiments, optionally, the wall thickness of the flexible sleeve 140 is W, where W ≤ 1 mm.

[0067] The greater the thickness of the flexible sleeve 140, the less prone it is to deformation. However, if the flexible sleeve 140 is in close contact with the intake muffler 120, misalignment can easily occur between them as the intake muffler 120 moves, resulting in a large gap between them. If this gap exists, the flexible sleeve 140 is more likely to make a sound when it touches the intake muffler 120.

[0068] In this design, the wall thickness of the flexible sleeve 140 is limited to less than or equal to 1 mm. Within this range, if the flexible sleeve 140 is in contact with the intake muffler 120, it is prone to deformation due to its small wall thickness, ensuring a stable fit. If there is a gap between the flexible sleeve 140 and the intake muffler 120, even if the flexible sleeve 140 is touched by the intake muffler 120, it is unlikely to produce noise, thus reducing the noise of the compressor 100 during operation.

[0069] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, a portion of the flexible sleeve 140 located inside the housing 110 is provided with a communication hole 143, and the flexible sleeve 140 and the interior of the housing 110 are connected through the communication hole 143.

[0070] A connecting hole 143 is formed on the flexible sleeve 140, which connects the inside of the housing 110 and the inside of the flexible sleeve 140, so that the air pressure between the inside of the housing 110 and the flexible sleeve 140 is balanced, which helps to improve the stability of the air intake process of the compressor 100.

[0071] In one possible embodiment, when the flexible sleeve includes a buffer portion 142, the connecting hole 143 is provided on the buffer portion 142. If the sleeve body 141 is provided with a large number of connecting holes 143, it will affect the structural stability of the sleeve body 141, causing the sleeve body 141 to be easily bent under the action of gravity. In this solution, the connecting hole 143 is provided on the buffer portion 142. This way, the buffer portion 142 can be more easily deformed, and by increasing the number of connecting holes 143, the air pressure balance effect between the inside of the shell 110 and the flexible sleeve 140 can be further improved.

[0072] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, the second end of the flexible sleeve 140 is flared, the opening area of ​​the second end of the flexible sleeve 140 is larger than the opening area of ​​the silencing inlet 121, and the second end of the flexible sleeve 140 covers the silencing inlet 121.

[0073] The flexible sleeve 140 is flared on the side facing the intake muffler 120, which allows the end of the flexible sleeve 140 to completely cover the muffler inlet 121, preventing air leakage between the flexible sleeve 140 and the intake muffler 120, and also preventing the temperature inside the housing 110 from affecting the intake air.

[0074] The end of the flexible sleeve 140 is set to be flared, and the radial dimension of other positions of the flexible sleeve 140 can be set to be smaller, so as to avoid the flexible sleeve 140 occupying too much space in the housing 110.

[0075] One end of the intake sleeve is fixedly installed inside the intake pipe 130, and the other end has a tapered flare. The maximum outer diameter at the edge of the flare completely covers the silencer inlet 121 of the intake silencer 120.

[0076] In some embodiments, the flexible sleeve 140 may optionally be a fluororubber suction tube.

[0077] The flexible sleeve 140 made of fluororubber has the advantages of good chemical stability, strong corrosion resistance and good compatibility. Fluororubber is not easy to react chemically with refrigerant and is not easily corroded, thus ensuring the structural stability of the flexible sleeve 140. Moreover, when fluorides are used as refrigerants, fluororubber can have good compatibility with refrigerants. When the two come into contact, they are not likely to interact and produce substances that are detrimental to the operation of the system, thus ensuring the stability and reliability of the system.

[0078] Of course, in other embodiments, the flexible sleeve 140 may also be made of other materials, such as rubber or silicone.

[0079] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, the outer surface of the flexible sleeve 140 is provided with a protrusion 144, the protrusion 144 is located outside the housing 110, the circumferential direction of the suction pipe 130 is provided with a receiving groove 131, the protrusion 144 extends into the receiving groove 131, and the protrusion 144 is located between the suction pipe 130 and the housing 110.

[0080] A receiving groove 131 is formed circumferentially in the intake pipe 130, and a protrusion 144 is formed on the outer surface of the flexible sleeve 140. The protrusion 144 can be embedded in the receiving groove 131. Moreover, the protrusion 144 is located between the intake pipe 130 and the housing 110. The intake pipe 130 and the housing 110 limit the protrusion 144, so the flexible sleeve 140 is not easy to move relative to the intake pipe 130 and the housing 110, thereby preventing the flexible sleeve 140 and the intake pipe 130 from separating and ensuring the connection stability of the flexible sleeve 140 and the intake pipe 130.

[0081] In the embodiments of this utility model, a refrigerator is proposed, which includes the compressor in any of the above embodiments and can achieve the same technical effect, and will not be described again here.

[0082] In this utility model, the term "multiple" refers to two or more unless otherwise explicitly defined.
