Description

Technical Field

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

[0002] As an essential household appliance in daily life, refrigerators have increasingly higher requirements for their volume utilization, reliability, and performance. The increase in refrigerator volume utilization inevitably requires a reduction in compressor compartment volume utilization, so compressor miniaturization has become an inevitable trend. Therefore, the volume utilization of the internal space of the compressor needs to be further improved. Currently, the method of building the intake pipe of the intake muffler inside reduces the space occupied by the intake muffler.

[0003] When the intake pipe of the intake muffler is built-in, the oil inside the compressor can easily flow into the interior of the intake muffler along the intake port on the surface of the intake muffler, resulting in an increase in the amount of oil discharged by the compressor, increasing the risk of oil blockage in the refrigeration system, and thus affecting the overall refrigeration performance of the machine. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of the above, in a first aspect, this utility model proposes a muffler, comprising: a housing, the housing having an air intake port, an oil drain port, an air intake pipe and an air outlet pipe, the air intake pipe being disposed inside the housing, the air intake port communicating with the air intake pipe, the oil drain port, the air intake pipe and the air outlet pipe all communicating with the inner cavity of the housing, the housing having a mounting surface, the air outlet pipe being disposed on the mounting surface, at least a portion of the mounting surface being inclined away from the air intake port; and an oil-blocking rib being disposed on the edge of the mounting surface, at least a portion of the oil-blocking rib being located on the side of the mounting surface adjacent to the air intake port.

[0006] The compressor casing has an intake port on its surface, and an intake pipe is located inside the casing, connecting the intake port and the casing's inner cavity. Refrigerant flows into the intake pipe from the intake port and then into the casing's inner cavity. The refrigerant flowing into the casing may carry some oil, which can drain out of the casing through an oil drain port. The refrigerant inside the casing flows out through the outlet pipe to the outside of the muffler.

[0007] The exhaust pipe is usually located at the top of the housing. In this design, the top surface of the housing is set as the mounting surface. During the operation of the compressor, as the rotating parts rotate, the rotating parts may throw the oil towards the muffler, which will cause the oil to accumulate on the mounting surface of the housing. If the oil flows to the side of the housing, the oil may be sucked into the suction port, resulting in an increase in the amount of oil discharged by the compressor.

[0008] In this design, oil-blocking ribs are installed on the mounting surface. These ribs are located at the edge of the mounting surface, with at least a portion positioned on the side of the mounting surface adjacent to the air intake. When oil accumulates on the mounting surface, the ribs can block the oil, preventing it from flowing from the side of the mounting surface near the air intake to the air intake. As the amount of oil accumulated on the mounting surface increases, to prevent the oil from flowing past the ribs and towards the air intake, this design limits at least a portion of the mounting surface to be inclined away from the air intake. Therefore, the oil on the mounting surface will also flow away from the air intake, thus preventing oil from accumulating above the air intake and effectively preventing oil from flowing towards the air intake. This not only reduces the overall oil discharge of the unit and lowers the risk of oil blockage in the refrigeration system, but also increases the proportion of refrigerant in the compression process, thereby improving the overall refrigeration performance.

[0009] In some technical solutions, the mounting surface may optionally include an inclined surface, which is inclined along a first direction and / or a second direction, with an angle between the first direction and the second direction, and a portion of the mounting surface adjacent to the air intake is higher than the lowest point of the inclined surface.

[0010] The mounting surface can be tilted in one direction or in two directions. For example, the mounting surface can be tilted along the length of the housing and at the same time along the width of the housing. This arrangement can further prevent oil from flowing into the air inlet.

[0011] A portion of the mounting surface near the air intake is higher than the lowest point of the inclined surface. The oil on the mounting surface will flow towards the lowest point of the mounting surface, thereby preventing the oil from accumulating near the air intake on the mounting surface and preventing the oil from flowing to the air intake after passing the oil-blocking rib.

[0012] For example, a portion of the mounting surface adjacent to the air intake can be the highest position of the mounting surface, or a portion of the mounting surface adjacent to the air intake can be lower than the highest position of the mounting surface but higher than the lowest position of the mounting surface.

[0013] It should be noted that the shortest line connecting the mounting surface and the air intake is defined in this solution as the portion of the mounting surface adjacent to the air intake, which refers to the position of the shortest line passing through the mounting surface.

[0014] In some technical solutions, the mounting surface may optionally include a bearing surface, which is connected to the inclined surface; the first part of the housing is provided with an inclined surface, the second part of the housing is provided with a bearing surface, the air intake is provided in the first part, and the air outlet is provided in the second part.

[0015] Part of the mounting surface is inclined, and the other part is a bearing surface. The inclined surface and the air intake are located on the first part of the housing. This arrangement is to make a portion of the mounting surface above the air intake inclined. The air outlet pipe is located on the bearing surface. The bearing surface can be non-inclined, or its shape can be adapted to the air outlet pipe. Dividing the mounting surface into two parts prevents oil from flowing into the air intake and facilitates the installation of the air outlet pipe on the bearing surface or the machining of the air outlet pipe on the bearing surface. That is, if the bearing surface were also inclined, the arrangement of the air outlet pipe would be more difficult.

[0016] In some technical solutions, optionally, the oil-blocking ribs are distributed circumferentially along the mounting surface, and the length of the oil-blocking ribs extending circumferentially along the mounting surface is less than the circumference of the mounting surface.

[0017] The oil-blocking ribs are positioned at the edge of the mounting surface, enabling them to effectively block oil. However, in this design, the length of the ribs along the circumference of the mounting surface is limited to less than the circumference of the mounting surface. This means the ribs do not completely cover the edge of the mounting surface. The ribs have notches along the circumference of the mounting surface, allowing oil on the surface to flow out of the area enclosed by the ribs. Furthermore, the ribs are not a closed structure, preventing the accumulation of oil on the mounting surface from gradually increasing and thus preventing oil from flowing past the ribs towards the air intake.

[0018] In some technical solutions, the muffler may optionally include: a partition located in the inner cavity of the housing, an air intake pipe connected to the partition, and the partition dividing the inner cavity into a first cavity and a second cavity, the partition being provided with an insertion tube, the first cavity and the second cavity being connected through the insertion tube, the partition being provided with an oil guide groove, and the side of the insertion tube being provided with a connecting hole, the oil guide groove being connected to the connecting hole.

[0019] A partition is installed inside the housing, and the partition divides the interior of the housing into a first cavity and a second cavity, which are connected by a tube.

[0020] Taking the first cavity connected to the air intake and the second cavity connected to the air outlet as an example, the refrigerant entering the housing may carry some oil. When the oil flows to the second cavity, the liquefied oil will drip onto the partition plate. The oil on the partition plate flows to the connecting hole through the oil guide groove. The oil flows into the insertion tube through the connecting hole, and then flows along the insertion tube to the first cavity and flows out of the housing through the oil drain port.

[0021] Taking a partition parallel to the horizontal direction as an example, the horizontally connected area of ​​the first and second cavities affects the muffler's noise reduction effect. If no opening is provided on the partition, the horizontally connected area of ​​the first and second cavities is the opening area of ​​the insertion tube. If an opening is provided on the partition to allow oil in the second cavity to flow into the first cavity, the horizontally connected area of ​​the first and second cavities is the sum of the opening area of ​​the insertion tube and the opening area of ​​the opening. In this case, the opening will affect the muffler's noise reduction effect. To solve the above problem, this solution provides a connecting hole on the side of the insertion tube and an oil guide groove on the partition. This arrangement avoids directly opening a hole on the partition, thus not increasing the horizontally connected area of ​​the first and second cavities, thereby ensuring the muffler's noise reduction effect.

[0022] In some technical solutions, optionally, the diameter of the connecting hole is L, where 1mm≤L≤2mm.

[0023] In this design, the diameter range of the connecting hole is limited to between 1mm and 2mm. This facilitates the discharge of accumulated oil without causing leakage in the upper and lower cavities, which would weaken the silencing capacity and thus ensure the silencing effect of the muffler.

[0024] In some technical solutions, optionally, the partition is provided with reinforcing ribs, the oil guide groove is located between the insertion tube and the reinforcing ribs, and the oil guide groove is located in the extending direction of the reinforcing ribs.

[0025] The partition is equipped with reinforcing ribs, which strengthen the structure of the partition, prevent the partition from deforming, and ensure that the partition does not affect the volume ratio of the first cavity and the second cavity, thereby ensuring the noise reduction effect of the muffler.

[0026] The presence of oil guide grooves on the partition plate would reduce the structural strength. In this design, the oil guide grooves are placed in the extension direction of the reinforcing ribs, so that the reinforcing ribs can strengthen the structure near the oil guide grooves, prevent deformation of the partition plate at the location of the oil guide grooves, and thus improve the structural strength of the partition plate.

[0027] In some technical solutions, the intake pipe may be integrally formed into the partition.

[0028] The integrated design of the intake pipe and baffle plate, with the intake pipe fixed to the baffle plate, makes it difficult for the position of the intake pipe to change. This, in turn, ensures that the positions of the intake pipe's inlet and outlet are not easily changed, guaranteeing that the refrigerant can flow stably into the housing along the set path, which helps to improve the silencer's noise reduction effect.

[0029] The integrated design of the intake pipe and baffle helps to reduce the difficulty of manufacturing the muffler.

[0030] In some technical solutions, the muffler may optionally include: a first baffle connected to the housing, the first baffle being located above the air intake; and / or a second baffle connected to the housing, the second baffle being located above the oil drain.

[0031] A first baffle is set above the air intake. The first baffle further prevents oil from flowing into the air intake. Even if some oil flows over the oil-blocking rib and into the air intake, the first baffle can block the oil, thereby further preventing the oil from being sucked into the air intake.

[0032] Similarly, a second baffle is installed above the oil leak. The second baffle has an oil-proof effect, preventing oil from flowing into the interior of the casing through the oil leak.

[0033] In some technical solutions, the housing may optionally include an upper housing and a lower housing, with the air outlet pipe located in the upper housing and the air intake and oil outlet located in the lower housing. The upper housing is provided with a slot, and the lower housing is provided with a plug-in part, which is inserted into the slot.

[0034] The housing has a split structure, which includes an upper housing and a lower housing. The upper and lower housings are connected by a plug-in connection. This split structure makes it easy to install the partition and intake pipe inside the housing.

[0035] In this design, the upper housing is equipped with a slot, and the lower housing is equipped with a plug-in part. During the use of the muffler, the opening of the slot faces downward. Even if oil flows along the side of the housing to the joint between the upper and lower housings, the oil will not flow into the slot, thus avoiding the accumulation of oil in the slot.

[0036] Secondly, this utility model proposes a compressor, including the silencer mentioned in the first aspect.

[0037] Thirdly, this utility model proposes a refrigerator, including the compressor described in the second aspect.

Detailed Implementation

[0052] 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.

[0053] 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.

[0054] The following reference Figures 1 to 10 The present invention describes a muffler, a compressor, and a refrigerator according to some embodiments thereof.

[0055] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments of this utility model, a muffler 100 is provided. The muffler 100 includes a housing 110 and an oil-blocking rib 120. The housing 110 is provided with an air intake 111, an oil drain 112, an air intake pipe 113, and an air outlet pipe 114. The air intake pipe 113 is disposed inside the housing 110, and the air intake 111 communicates with the air intake pipe 113. The oil drain 112, the air intake pipe 113, and the air outlet pipe 114 are all communicated with the inner cavity 161 of the housing 110. The housing 110 has a mounting surface 115, and the air outlet pipe 114 is disposed on the mounting surface 115. At least a portion of the mounting surface 115 is inclined away from the air intake 111. The oil-blocking rib 120 is disposed on the edge of the mounting surface 115, and at least a portion of the oil-blocking rib 120 is located on the side of the mounting surface 115 adjacent to the air intake 111.

[0056] The compressor housing 110 has an intake port 111 on its surface, and an intake pipe 113 is located inside the housing 110. The intake port 111 and the inner cavity 161 of the housing 110 are connected through the intake pipe 113. Refrigerant flows into the intake pipe 113 from the intake port 111, and then into the inner cavity 161 of the housing 110 through the intake pipe 113. The refrigerant flowing into the housing 110 may carry some oil, which can flow out of the housing 110 through the oil drain port 112. The refrigerant inside the housing 110 flows out to the outside of the muffler 100 through the outlet pipe 114.

[0057] The exhaust pipe 114 is usually located on the top of the housing 110. In this design, the top surface of the housing 110 is set as the mounting surface 115. During the operation of the compressor, as the rotating parts rotate, the rotating parts may throw oil towards the muffler 100, which will cause oil to accumulate on the mounting surface 115 of the housing 110. If the oil flows to the side of the housing 110, the oil may be sucked into the suction port 111, resulting in an increase in the amount of oil discharged by the compressor.

[0058] In this design, an oil-blocking rib 120 is provided on the mounting surface 115. The oil-blocking rib 120 is located at the edge of the mounting surface 115, and at least a portion of the oil-blocking rib 120 is provided on the side of the mounting surface 115 adjacent to the air intake 111. When oil accumulates on the mounting surface 115, the oil-blocking rib 120 can block the oil and prevent the oil from flowing from the side of the mounting surface 115 adjacent to the air intake 111 to the air intake 111. As the amount of oil accumulated on the mounting surface 115 increases, in order to prevent the oil from flowing towards the intake port 111 after passing over the oil-blocking rib 120, this solution limits at least a portion of the mounting surface 115 to be tilted away from the intake port 111. Therefore, the oil on the mounting surface 115 will also flow away from the intake port 111, thereby preventing the oil from accumulating above the intake port 111 and effectively preventing the oil from flowing towards the intake port 111. This not only reduces the amount of oil discharged by the whole machine and reduces the risk of oil blockage in the refrigeration system, but also increases the proportion of refrigerant in the compression process, thereby improving the overall refrigeration performance.

[0059] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the mounting surface 115 includes an inclined surface 116, the inclined surface 116 being inclined along a first direction and / or a second direction, the first direction and the second direction having an included angle, and a portion of the mounting surface 115 adjacent to the air intake 111 being higher than the lowest point of the inclined surface 116.

[0060] The mounting surface 115 can be tilted in one direction or in two directions. For example, the mounting surface 115 can be tilted along the length of the housing 110 and at the same time tilted along the width of the housing 110. This arrangement can further prevent oil from flowing to the air inlet.

[0061] A portion of the mounting surface 115 adjacent to the air intake 111 is higher than the lowest position of the inclined surface 116. The oil on the surface of the mounting surface 115 will flow towards the lowest position of the mounting surface 115, thereby preventing the oil from accumulating at the position of the mounting surface 115 adjacent to the air intake 111 and preventing the oil from flowing to the air intake 111 after passing the oil-blocking rib 120.

[0062] For example, the inclined surface 116 in this embodiment can be an arc surface or an inclined surface.

[0063] For example, a portion of the mounting surface 115 adjacent to the air intake 111 may be the highest position of the mounting surface 115, or a portion of the mounting surface 115 adjacent to the air intake 111 may be lower than the highest position of the mounting surface 115 and higher than the lowest position of the mounting surface 115.

[0064] It should be noted that the shortest connection between the mounting surface 115 and the air intake 111 is defined in this scheme as the part of the mounting surface 115 adjacent to the air intake 111, which refers to the position where the shortest connection passes through the mounting surface 115.

[0065] Figure 3 and Figure 4 The arrows in the diagram are used to indicate the direction of oil flow on the inclined surface 116.

[0066] like Figure 3 As shown, in this embodiment, the inclined surface 116 is inclined in the direction of arrow E1. Of course, in other embodiments, the inclined surface 116 may also be inclined in the direction of arrow E2 or arrow E3, or the inclined surface 116 may be inclined in both the direction of arrow E1 and the direction of arrow E2, or the inclined surface 116 may be inclined in both the direction of arrow E3 and the direction of arrow E2. Of course, the inclination direction of the inclined surface 116 is not limited to this. Figure 3 The three directions shown in the figure can be located between arrows E1 and E2, or between arrows E2 and E3, as long as the oil can flow along the inclined surface 116 in a direction away from the air intake 111.

[0067] In this embodiment, the first direction refers to Figure 3 The direction indicated by the middle arrow E1, the second direction refers to Figure 3 The direction indicated by the middle arrow E2.

[0068] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the mounting surface 115 may optionally include a bearing surface 117, which is connected to the inclined surface 116. The first part 118 of the housing 110 is provided with the inclined surface 116, the second part 119 of the housing 110 is provided with the bearing surface 117, the air intake 111 is provided in the first part 118, and the air outlet 114 is provided in the second part 119.

[0069] A portion of the mounting surface 115 is an inclined surface 116, and another portion is a bearing surface 117. The inclined surface 116 and the air intake 111 are located on the first portion 118 of the housing 110. This arrangement is to make a portion of the mounting surface 115 above the air intake 111 inclined. The bearing surface 117 is provided with an air outlet pipe 114. The bearing surface 117 can be non-inclined, or its shape can be adapted to the air outlet pipe 114. Dividing the mounting surface 115 into two parts can prevent oil from flowing to the air intake 111 and also facilitate the installation of the air outlet pipe 114 on the bearing surface 117 or the machining of the air outlet pipe 114 on the bearing surface 117. That is, if the bearing surface 117 is also inclined, it will be more difficult to arrange the air outlet pipe 114.

[0070] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the oil-blocking rib 120 is circumferentially aligned with the mounting surface 115. Figure 7 The arrow at point O points to the distribution along the circumference of the mounting surface 115, and the length of the oil-blocking rib 120 is less than the circumference of the mounting surface 115.

[0071] The oil-blocking rib 120 is positioned at the edge of the mounting surface 115, enabling it to effectively block oil. In this design, the length of the oil-blocking rib 120 along the circumference of the mounting surface 115 is less than the circumference of the mounting surface 115. That is, the oil-blocking rib 120 does not completely cover the edge of the mounting surface 115. The oil-blocking rib 120 has a notch along the circumference of the mounting surface 115, allowing oil on the surface of the mounting surface 115 to flow out of the area enclosed by the oil-blocking rib 120. The oil-blocking rib 120 is not a closed structure along the circumference of the mounting surface 115, preventing the amount of oil accumulating on the mounting surface 115 from gradually increasing, thereby preventing oil from flowing past the oil-blocking rib 120 towards the air intake 111.

[0072] Combination Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, optionally, the muffler 100 further includes: a partition 130, the partition 130 being located in the inner cavity 161 of the housing 110, the intake pipe 113 being connected to the partition 130, and the partition 130 dividing the inner cavity 161 into a first cavity 162 and a second cavity 163, the partition 130 being provided with an insertion tube 140, the first cavity 162 and the second cavity 163 being connected through the insertion tube 140, the partition 130 being provided with an oil guide groove 131, and the side of the insertion tube 140 being provided with a connecting hole 141, the oil guide groove 131 being connected to the connecting hole 141.

[0073] The partition 130 is disposed inside the housing 110, and the partition 130 divides the interior of the housing 110 into a first cavity 162 and a second cavity 163, which are connected by a tube 140.

[0074] Taking the first cavity 162 connected to the air intake 111 and the second cavity 163 connected to the air outlet 114 as an example, the refrigerant entering the housing 110 may carry some oil. When the oil flows to the second cavity 163, the liquefied oil will drip onto the partition 130. The oil on the partition 130 flows to the connecting hole 141 through the oil guide groove 131. The oil flows into the insertion tube 140 through the connecting hole 141. Then the oil flows along the insertion tube 140 to the first cavity 162 and flows out of the housing 110 through the oil drain 112.

[0075] Taking the partition 130 as an example parallel to the horizontal direction, the horizontal connection area of ​​the first cavity 162 and the second cavity 163 will affect the noise reduction effect of the muffler 100. If no opening is provided on the partition 130, the horizontal connection area of ​​the first cavity 162 and the second cavity 163 is the opening area of ​​the insertion tube 140. If an opening is provided on the partition 130, the opening is used to allow the oil in the second cavity 163 to flow to the first cavity 162. At this time, the horizontal connection area of ​​the first cavity 162 and the second cavity 163 is the opening area of ​​the insertion tube 140 plus the opening area of ​​the opening. In this case, the opening will affect the noise reduction effect of the muffler 100. To solve the above problems, this solution provides a connecting hole 141 on the side of the insertion tube 140 and an oil guide groove 131 on the partition 130. This arrangement does not directly open a hole on the partition 130, thus not increasing the horizontal connection area between the first cavity 162 and the second cavity 163, thereby ensuring the noise reduction effect of the muffler 100.

[0076] In some embodiments, the diameter of the connecting hole 141 is optionally L, where 1mm ≤ L ≤ 2mm.

[0077] In this design, the diameter range of the connecting hole 141 is limited to between 1mm and 2mm. This facilitates the discharge of accumulated oil and prevents leakage in the upper and lower cavities, which would weaken the silencing capacity and thus ensure the silencing effect of the muffler 100.

[0078] Combination Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, optionally, a reinforcing rib 132 is provided on the partition 130, and an oil guide groove 131 is located between the insertion tube 140 and the reinforcing rib 132, and the oil guide groove 131 is located in the extending direction of the reinforcing rib 132. Figure 9The arrow at point H points upwards.

[0079] The partition 130 is provided with reinforcing ribs 132, which can strengthen the structure of the partition 130, prevent the partition 130 from deforming, and ensure that the partition 130 does not affect the volume ratio of the first cavity 162 and the second cavity 163, thereby ensuring the noise reduction effect of the muffler 100.

[0080] The location of the oil guide groove 131 on the partition 130 will reduce the structural strength. In this solution, the oil guide groove 131 is located in the extension direction of the reinforcing rib 132, so that the reinforcing rib 132 can strengthen the structure near the oil guide groove 131, avoid deformation at the location of the oil guide groove 131 on the partition 130, and thus improve the structural strength of the partition 130.

[0081] In some embodiments, the intake pipe 113 may be integrally formed on the partition 130.

[0082] The intake pipe 113 and the partition plate 130 are integrated. The intake pipe 113 is fixed to the partition plate 130, which makes it difficult for the position of the intake pipe 113 to change. This ensures that the position of the inlet and outlet of the intake pipe 113 is not easily changed, and that the refrigerant can flow into the housing 110 stably along the set path, which is beneficial to improving the noise reduction effect of the silencer 100.

[0083] The integrated design of the intake pipe 113 and the baffle 130 helps to reduce the processing difficulty of the silencer 100.

[0084] When the intake pipe 113 and the partition 130 are integrated, the reinforcing rib 132 strengthens the structure of the partition 130 to ensure that the intake pipe 113 will not cause the partition 130 to deform under the action of gravity.

[0085] In some embodiments, the muffler 100 may optionally include a first baffle 151 and / or a second baffle 152, wherein the first baffle 151 is connected to the housing 110 and is located above the air intake 111, and the second baffle 152 is located above the oil drain 112.

[0086] A first baffle 151 is provided above the air intake 111. The first baffle 151 further serves to prevent oil from flowing into the air intake 111. Even if some oil flows past the oil-blocking rib 120 and into the air intake 111, the first baffle 151 can block the oil, thereby further preventing the oil from being sucked into the air intake 111.

[0087] Similarly, a second baffle 152 is provided above the oil drain 112. The second baffle 152 has an oil-proof effect, preventing oil from flowing into the interior of the housing 110 through the oil drain 112.

[0088] In this embodiment, the first baffle 151 and the second baffle 152 are arc-shaped, and the openings of the first baffle 151 and the second baffle 152 face downwards. This can prevent the oil from flowing along the first baffle 151 to the air intake 111 and prevent the oil from flowing along the second baffle 152 to the oil leak 112.

[0089] The intake port 111 has a center line F1, and the end of the first baffle 151 is lower than the center line F1, further reducing the probability of oil flowing into the intake port 111. The drain port 112 has a center line F2, and the end of the second baffle 152 is lower than the center line F2, further reducing the probability of oil flowing into the drain port 112.

[0090] Combination Figure 1 , Figure 2 and Figure 8 As shown, in some embodiments, optionally, the housing 110 includes an upper housing 164 and a lower housing 165, with an air outlet 114 disposed on the upper housing 164, and an air intake and an oil drain disposed on the lower housing 165. The upper housing 164 is provided with a slot 166, and the lower housing 165 is provided with a plug-in portion 167, which is plugged into the slot 166.

[0091] The housing 110 has a split structure, that is, the housing 110 includes an upper housing 164 and a lower housing 165. The upper housing 164 and the lower housing 165 are connected by a plug-in connection. Setting the housing 110 as a split structure makes it easy to install the partition 130 and the air intake pipe 113 inside the housing 110.

[0092] In this design, the upper housing 164 is provided with a slot 166, and the lower housing 165 is provided with a plug-in part 167. During the use of the muffler 100, the opening of the slot 166 faces downward. Even if oil flows along the side of the housing 110 to the splice position between the upper housing 164 and the lower housing 165, the oil will not flow into the slot 166, thereby preventing the oil from accumulating in the slot 166.

[0093] In an embodiment of this utility model, an anti-oil suction silencer structure and a compressor having the same are disclosed. The suction silencer 100 for the compressor includes: an upper housing 164, a lower housing 165, and an integrated partition and pipe. The upper housing 164 integrates the exhaust pipe 114 and the slot 166 of the silencer 100. The exhaust pipe 114 is fitted inside the cylinder head of the compressor. The upper surface of the upper housing 164 is an arc surface, and the outer edge of the upper surface is provided with an oil-blocking rib 120. The lower housing 165 has an intake port 111. The side wall of the lower housing 165 has a first baffle rib 151 on the outer ring of the intake port 111. The bottom side wall of the lower housing 165 is provided with an oil leakage port 112 and a second baffle rib 152. The lower housing 165 is provided with a plug-in part 167 corresponding to the slot 166 of the upper housing 164. A partition 130 divides the interior of the silencer 100 into upper and lower chambers. The partition 130 is equipped with reinforcing ribs 132 and a connecting hole 141, which laterally connects to the side wall of the insertion tube 140. The insertion tube 140 on the partition 130 connects the upper and lower chambers and is coaxial with the outlet pipe 114. An intake pipe 113 is integrated into the partition 130 via the reinforcing ribs 132 and connects to the intake port 111 of the housing. By using this intake silencer 100, the amount of lubricating oil drawn into the silencer 100 and the entire compression cycle system can be significantly reduced. This not only reduces the overall oil discharge and lowers the risk of oil blockage in the refrigeration system, but also increases the proportion of refrigerant in the compression process, thereby improving the overall refrigeration performance. Simultaneously, the integrated partition and built-in intake pipe structure of this invention efficiently utilize the internal space of the compressor, ensuring good noise reduction performance.

[0094] Two technical features are added to the lubricating oil flow path: first, the upper surface of the muffler 100 is set as an arc surface; second, oil-blocking ribs 120 are set on the outer edge of the upper surface. These features can prevent the lubricating oil from flowing towards the air intake 111 and being sucked into the muffler 100.

[0095] The diameter of the connecting hole 141 is 1mm to 2mm, which facilitates the discharge of accumulated oil without causing leakage in the upper and lower cavities, thus reducing the noise reduction capability.

[0096] In the embodiments of this utility model, a compressor is proposed, which includes the muffler in any of the above embodiments and can achieve the same technical effect, which will not be described again here.

[0097] In this embodiment, the compressor is a reciprocating compressor. The muffler is assembled inside the compressor cylinder head through the assembly structure at its outlet pipe. The intake port of the muffler structure is aligned with the intake pipe port on the compressor housing to draw in refrigerant.
