Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to a muffler, a compressor and a refrigerator. Background Art

[0002] Refrigerators are essential household appliances in daily life, and people have increasingly higher requirements for their volume utilization, reliability, and performance. The increase in the volume ratio of refrigerators inevitably requires a reduction in the volume ratio of the compressor compartment. Therefore, the miniaturization of compressors has become an inevitable trend. Therefore, the volume utilization of the suction muffler on the internal space of the compressor needs to be further improved. At present, the suction pipe of the suction muffler is built-in to reduce the space occupied by the suction muffler.

[0003] When the suction pipe of the suction muffler is built-in, the oil inside the compressor can easily flow into the interior of the suction muffler along the suction port on the surface of the suction muffler, resulting in an increase in the oil discharge volume of the compressor and an increase in the risk of oil blockage in the refrigeration system, thereby affecting the refrigeration performance of the entire machine. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, in the first aspect, the present invention proposes a muffler, comprising: a shell, the shell being provided with an air intake port, an oil leakage port, an air intake pipe and an air outlet pipe, the air intake pipe being arranged in the shell, the air intake port being connected with the air intake pipe, the oil leakage port, the air intake pipe and the air outlet pipe being all connected with the inner cavity of the shell, the shell having a mounting surface, the air outlet pipe being arranged on the mounting surface, at least a portion of the mounting surface being inclined away from the air intake port; an oil-blocking rib being arranged on the edge of the mounting surface, at least a portion of the oil-blocking rib being located on a side of the mounting surface adjacent to the air intake port.

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

[0007] The exhaust pipe is usually arranged at the top of the shell. In this solution, the top surface of the shell is set as the mounting surface. During the operation of the compressor, as the rotating parts rotate, the rotating parts may throw the oil toward the muffler, causing oil to accumulate on the mounting surface of the shell. If the oil flows to the side of the shell, the oil may be sucked into the intake port, resulting in an increase in the oil discharge volume of the compressor.

[0008] In this solution, an oil-blocking rib is provided on the mounting surface. The oil-blocking rib is located at the edge of the mounting surface, and at least a portion of the oil-blocking rib is provided on the side of the mounting surface adjacent to the air inlet. When oil accumulates on the mounting surface, the oil-blocking rib can block the oil and prevent the oil from flowing from the side of the mounting surface adjacent to the air inlet to the air inlet. As the amount of oil accumulated on the mounting surface increases, in order to prevent the oil from flowing to the air inlet after passing over the oil-blocking rib, the present solution stipulates that at least a portion of the mounting surface is tilted away from the air inlet. Therefore, the oil on the mounting surface will also flow in a direction away from the air inlet, thereby preventing the oil from accumulating above the air inlet and effectively preventing the oil from flowing to the air inlet. This can not only reduce the oil discharge of the entire machine and reduce the risk of oil blockage in the refrigeration system, but also increase the proportion of refrigerant in the compression process, thereby improving the refrigeration performance of the entire machine.

[0009] In some technical solutions, optionally, the mounting surface includes an inclined surface, which is inclined along the first direction and / or the second direction, and there is 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 may be tilted in one direction or in two directions. For example, the mounting surface may be tilted in both the length direction and the width direction of the housing. This arrangement may further prevent oil from flowing toward the air inlet.

[0011] A portion of the mounting surface adjacent to the air intake port is higher than the lowest position of the inclined surface, and the oil on the mounting surface will flow toward the lowest position of the mounting surface, thereby preventing the oil from accumulating at a position of the mounting surface adjacent to the air intake port and preventing the oil from flowing toward the air intake port after passing over the oil retaining rib.

[0012] Illustratively, a portion of the mounting surface adjacent to the air inlet may be the highest position of the mounting surface, or a portion of the mounting surface adjacent to the air inlet may be lower than the highest position of the mounting surface and higher than the lowest position of the mounting surface.

[0013] It should be noted that the shortest line between the mounting surface and the air inlet is defined in this solution as a portion of the mounting surface adjacent to the air inlet, which refers to the position where the shortest line passes through the mounting surface.

[0014] In some technical solutions, optionally, the mounting surface also includes a bearing surface, which is connected to the inclined surface; the first part in the shell is provided with an inclined surface, the second part in the shell 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 an inclined surface, and the other part is a bearing surface. The inclined surface and the air intake are arranged on the first portion of the housing. This arrangement is designed to provide an inclined portion of the mounting surface above the air intake. The air outlet pipe is provided on the bearing surface. The bearing surface can be non-inclined, or its shape can be adapted to accommodate the air outlet pipe. Dividing the mounting surface into two parts prevents oil from flowing toward the air intake and facilitates installation of the air outlet pipe on the bearing surface or forming the air outlet pipe on the bearing surface. Specifically, if the bearing surface is also inclined, placement of the air outlet pipe becomes more difficult.

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

[0017] The oil-blocking ribs are positioned at the edges of the mounting surface, effectively blocking oil. However, in this embodiment, the ribs are limited in length along the circumference of the mounting surface to be less than the circumference of the mounting surface. That is, the ribs do not completely cover the edges of the mounting surface. The ribs have gaps along the circumference of the mounting surface, allowing oil on the mounting surface to flow out of the area surrounded by the ribs along the gaps. The ribs are not enclosed circumferentially, preventing the accumulation of oil on the mounting surface from gradually increasing, thereby preventing oil from flowing past the ribs and toward the air intake.

[0018] In some technical solutions, optionally, the muffler also includes: a partition, located in the inner cavity of the shell, the intake pipe is connected to the partition, and the partition divides the inner cavity into a first cavity and a second cavity, the partition is provided with a cannula, the first cavity and the second cavity are connected through the cannula, the partition is provided with an oil guide groove, the side of the cannula is provided with a connecting hole, and the oil guide groove is connected to the connecting hole.

[0019] The partition is arranged in the shell, and the partition divides the interior of the shell into a first cavity and a second cavity. The first cavity and the second cavity are connected through a cannula.

[0020] Taking the first cavity connected to the air intake port and the second cavity connected to the air outlet pipe as an example, the refrigerant entering the shell may carry a portion of oil. After the oil flows to the second cavity, the liquefied oil will drip onto the partition. The oil on the partition flows to the connecting hole through the oil guide groove. The oil flows into the insert tube from the connecting hole, and then the oil flows along the insert tube to the first cavity and flows out of the shell through the oil leakage port.

[0021] Taking the partition plate parallel to the horizontal direction as an example, the horizontal connection area between the first cavity and the second cavity will affect the muffler effect. If there is no opening on the partition plate, the horizontal connection area between the first cavity and the second cavity is the opening area of ​​the insert tube. If an opening is set on the partition plate, the opening is used to allow the oil in the second cavity to flow to the first cavity. At this time, the horizontal connection area between the first cavity and the second cavity is the opening area of ​​the insert tube plus the opening area of ​​the opening. At this time, the opening will affect the muffler effect. In order to solve the above problem, in this solution, a connecting hole is set on the side of the insert tube and an oil guide groove is set on the partition plate. This setting method does not directly open a hole on the partition plate, so it will not increase the horizontal connection area between the first cavity and the second cavity, thereby ensuring the muffler effect.

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

[0023] In this solution, the aperture range of the connecting hole is limited to between 1mm and 2mm, which is conducive to the discharge of accumulated oil and does not cause leakage in the upper and lower chambers, resulting in a weakening of the silencer ability, thereby ensuring the silencer effect of the silencer.

[0024] In some technical solutions, optionally, a reinforcing rib is provided on the partition, the oil guide groove is located between the insert tube and the reinforcing rib, and the oil guide groove is located in the extension direction of the reinforcing rib.

[0025] The partition is provided with reinforcing ribs, which can strengthen the structure of the partition, prevent the partition from deformation, and ensure that the partition does not affect the volume ratio of the first cavity and the second cavity, thereby ensuring the silencer effect of the silencer.

[0026] The location where the oil guide groove is set on the partition will reduce the structural strength. In this solution, the oil guide groove is set in the extension direction of the reinforcing rib, so that the reinforcing rib can strengthen the structure near the oil guide groove, avoiding deformation of the location where the oil guide groove is set on the partition, thereby improving the structural strength of the partition.

[0027] In some technical solutions, optionally, the intake pipe is integrally formed with the partition.

[0028] The suction pipe and the partition are integrated into the design. The suction pipe is fixed to the partition, so that the position of the suction pipe is not easy to change, and the positions of the inlet and outlet of the suction pipe are not easy to change, ensuring that the refrigerant can flow stably into the shell along the set path, which is beneficial to improving the silencer effect of the silencer.

[0029] The integrated arrangement of the intake pipe and the partition helps to reduce the difficulty of processing the muffler.

[0030] In some technical solutions, optionally, the muffler further includes: a first baffle rib connected to the shell, the first baffle rib being located above the air intake port; and / or a second baffle rib connected to the shell, the second baffle rib being located above the oil leakage port.

[0031] A first baffle is provided above the air intake port, which further plays an oil-proof role. Even if some oil flows over the oil-blocking rib and toward the air intake port, the first baffle can block the oil, thereby further preventing the oil from being sucked into the air intake port.

[0032] Similarly, a second retaining rib is provided above the oil leakage port, and the second retaining rib has an oil-proof effect, preventing the oil from flowing into the interior of the housing through the oil leakage port.

[0033] In some technical solutions, optionally, the shell includes an upper shell and a lower shell, the air outlet pipe is arranged on the upper shell, the air intake and oil leakage port are arranged on the lower shell, the upper shell is provided with a slot, and the lower shell is provided with a plug-in part, which is plugged into the slot.

[0034] The shell is a split structure, that is, the shell includes an upper shell and a lower shell, and the upper shell and the lower shell are connected by plugging. Setting the shell as a split structure can facilitate the arrangement of the partition and the intake pipe in the shell.

[0035] In this solution, a slot is provided in the upper shell and a plug-in portion is provided in the lower shell. When the muffler is in use, the opening of the slot faces downward. Even if oil flows along the side of the shell to the joint between the upper shell and the lower shell, the oil will not flow into the slot, thereby avoiding oil accumulation in the slot.

[0036] In a second aspect, the present invention provides a compressor comprising the muffler in the first aspect.

[0037] In a third aspect, the present invention provides a refrigerator comprising the compressor in the second aspect.

DETAILED DESCRIPTION

[0052] 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.

[0053] 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.

[0054] Refer to the following Figures 1 to 10A silencer, a compressor, and a refrigerator according to some embodiments of the present invention are described.

[0055] Combine Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, in some embodiments of the present invention, 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 port 111, an oil leakage port 112, an air intake pipe 113, and an air outlet pipe 114. The air intake pipe 113 is disposed within the housing 110, and the air intake port 111 is in communication with the air intake pipe 113. The oil leakage port 112, the air intake pipe 113, and the air outlet pipe 114 are all in communication 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 port 111. The oil-blocking rib 120 is disposed at an edge of the mounting surface 115, and at least a portion of the oil-blocking rib 120 is located on a side of the mounting surface 115 adjacent to the air intake port 111.

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

[0057] The exhaust pipe 114 is usually arranged at the top of the shell 110. In this solution, the top surface of the shell 110 is set as the mounting surface 115. During the operation of the compressor, as the rotating parts rotate, the rotating parts may throw the oil toward the muffler 100, thereby causing oil to accumulate on the mounting surface 115 of the shell 110. If the oil flows to the side of the shell 110, the oil may be sucked into the intake port 111, resulting in an increase in the oil discharge volume of the compressor.

[0058] In this solution, 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 port 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 port 111 to the air intake port 111. As the amount of oil accumulated on the mounting surface 115 increases, in order to prevent the oil from flowing over the oil retaining rib 120 and then flowing towards the air intake port 111, the present solution stipulates that at least a portion of the mounting surface 115 is inclined in a direction away from the air intake port 111. Therefore, the oil on the mounting surface 115 will also flow in a direction away from the air intake port 111, thereby preventing the oil from accumulating above the air intake port 111 and effectively preventing the oil from flowing towards the air intake port 111. This can not only reduce the oil discharge volume of the entire machine and reduce the risk of oil blockage in the refrigeration system, but also increase the proportion of refrigerant in the compression process, thereby improving the refrigeration performance of the entire machine.

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

[0060] The mounting surface 115 can be tilted in one direction, or the mounting surface 115 can be tilted in two directions. For example, the mounting surface 115 can be tilted along the length direction of the shell 110, and the mounting surface 115 can be tilted along the width direction of the shell 110. This setting can further prevent oil from flowing toward the air inlet.

[0061] A portion of the mounting surface 115 adjacent to the air intake port 111 is higher than the lowest position of the inclined surface 116. The oil on the surface of the mounting surface 115 will flow toward the lowest position of the mounting surface 115, thereby avoiding the accumulation of oil at the position of the mounting surface 115 adjacent to the air intake port 111, and preventing the oil from flowing toward the air intake port 111 after passing over the oil retaining rib 120.

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

[0063] Exemplarily, a portion of the mounting surface 115 adjacent to the air inlet 111 may be the highest position of the mounting surface 115 , or a portion of the mounting surface 115 adjacent to the air inlet 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 mounting surface 115 and the air inlet 111 are connected by the shortest line. In this solution, the portion of the mounting surface 115 adjacent to the air inlet 111 refers to the position where the shortest line passes through the mounting surface 115 .

[0065] Figure 3 and Figure 4 The arrow in FIG. 1 is used to indicate the direction of oil flow on the surface of the inclined surface 116 .

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

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

[0068] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, optionally, the mounting surface 115 further includes a bearing surface 117, which is connected to the inclined surface 116. The first portion 118 of the housing 110 is provided with the inclined surface 116, and the second portion 119 of the housing 110 is provided with the bearing surface 117. The air inlet 111 is provided at the first portion 118, and the air outlet pipe 114 is provided at the second portion 119.

[0069] A portion of the mounting surface 115 is an inclined surface 116, and the other portion is a bearing surface 117. The inclined surface 116 and the air inlet 111 are arranged on the first portion 118 of the housing 110. This arrangement is intended to set a portion of the mounting surface 115 above the air inlet 111 in an inclined shape. An air outlet pipe 114 is arranged on the bearing surface 117. The bearing surface 117 can be set as a non-inclined surface, or the shape of the bearing surface 117 can be adapted to the air outlet pipe 114. Dividing the mounting surface 115 into two portions can prevent oil from flowing toward the air inlet 111 and can also facilitate the installation of the air outlet pipe 114 on the bearing surface 117 or the processing and forming 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] Combine Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, optionally, the oil retaining rib 120 is arranged along the circumference of the mounting surface 115 ( Figure 7 (As indicated by the arrow at O ​​in the figure), the oil retaining rib 120 extends along the circumference of the mounting surface 115 and has a length that is less than the circumference of the mounting surface 115.

[0071] The oil-blocking rib 120 is disposed at the edge of the mounting surface 115 so that it can effectively block oil. However, in this embodiment, the length of the oil-blocking rib 120 along the circumference of the mounting surface 115 is limited to 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 surrounded by the oil-blocking rib 120 along the notch. The oil-blocking rib 120 is not a closed structure along the circumference of the mounting surface 115, which prevents the amount of oil accumulated on the mounting surface 115 from gradually increasing, thereby preventing oil from flowing past the oil-blocking rib 120 and toward the air intake 111.

[0072] Combine 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 is located in the inner cavity 161 of the shell 110, the intake pipe 113 is connected to the partition 130, and the partition 130 divides the inner cavity 161 into a first cavity 162 and a second cavity 163, the partition 130 is provided with a cannula 140, the first cavity 162 and the second cavity 163 are connected through the cannula 140, the partition 130 is provided with an oil guide groove 131, and a connecting hole 141 is provided on the side of the cannula 140, and the oil guide groove 131 is connected to the connecting hole 141.

[0073] The partition 130 is disposed in the housing 110 , and the partition 130 divides the interior of the housing 110 into a first cavity 162 and a second cavity 163 . The first cavity 162 and the second cavity 163 are connected via the cannula 140 .

[0074] Taking the first cavity 162 connected to the air intake port 111 and the second cavity 163 connected to the air outlet pipe 114 as an example, the refrigerant entering the shell 110 may carry a portion of oil. After 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 insert tube 140 from the connecting hole 141, and then the oil flows along the insert tube 140 to the first cavity 162 and flows out of the shell 110 through the oil leakage port 112.

[0075] Taking the partition 130 parallel to the horizontal direction as an example, the horizontal connection area between the first cavity 162 and the second cavity 163 will affect the silencing effect of the silencer 100. If no opening is set on the partition 130, the horizontal connection area between the first cavity 162 and the second cavity 163 is the opening area of ​​the insert 140. If an opening is set 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 between the first cavity 162 and the second cavity 163 is the opening area of ​​the insert 140 plus the opening area of ​​the opening. At this time, the opening will affect the silencing effect of the silencer 100. In order to solve the above problems, in this solution, a connecting hole 141 is set on the side of the tube 140, and an oil guide groove 131 is set on the partition 130. This setting method does not directly open a hole on the partition 130, so as not to increase the connecting area of ​​the first cavity 162 and the second cavity 163 in the horizontal direction, thereby ensuring the silencing effect of the silencer 100.

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

[0077] In this solution, the aperture range of the connecting hole 141 is limited to between 1 mm and 2 mm, which is conducive to the discharge of accumulated oil and does not cause leakage in the upper and lower chambers to reduce the silencer ability, thereby ensuring the silencer effect of the silencer 100.

[0078] Combine 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 the oil guide groove 131 is located between the insert 140 and the reinforcing rib 132, and the oil guide groove 131 is located in the extension direction of the reinforcing rib 132 ( Figure 9The arrow at H in the figure points upward).

[0079] The partition 130 is provided with reinforcing ribs 132, which can strengthen the structure of the partition 130, prevent the partition 130 from deformation, 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 sound-absorbing effect of the muffler 100.

[0080] The position where the oil guide groove 131 is set on the partition 130 will reduce the structural strength. In this solution, the oil guide groove 131 is set 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, thereby avoiding deformation of the position where the oil guide groove 131 is set on the partition 130, thereby improving the structural strength of the partition 130.

[0081] In some embodiments, optionally, the air intake pipe 113 is integrally formed with the partition 130 .

[0082] The intake pipe 113 and the partition 130 are integrated in design, and the intake pipe 113 is fixed to the partition 130, so that the position of the intake pipe 113 is not easy to change, and the positions of the inlet and outlet of the intake pipe 113 are not easy to change, ensuring that the refrigerant can flow stably into the interior of the shell 110 along a set path, which is beneficial to improving the silencing effect of the silencer 100.

[0083] The air intake pipe 113 and the partition plate 130 are integrated into one body, which helps to reduce the difficulty of processing the muffler 100 .

[0084] When the air intake pipe 113 and the partition plate 130 are integrated, the reinforcing ribs 132 strengthen the structure of the partition plate 130 to ensure that the air intake pipe 113 does not cause the partition plate 130 to deform under the action of gravity.

[0085] In some embodiments, optionally, the muffler 100 further includes: a first barrier rib 151 and / or a second barrier rib 152, the first barrier rib 151 is connected to the shell 110, the first barrier rib 151 is located above the air intake port 111, the first barrier rib 151 is connected to the shell 110, and the second barrier rib 152 is located above the oil leakage port 112.

[0086] A first baffle 151 is provided above the air intake port 111, and the first baffle 151 further plays an oil-proof effect. Even if some oil flows over the oil-blocking rib 120 and toward the air intake port 111, the first baffle 151 can block the oil, thereby further preventing the oil from being sucked into the air intake port 111.

[0087] Likewise, a second retaining rib 152 is provided above the oil leakage port 112 . The second retaining rib 152 serves to prevent oil from flowing into the interior of the housing 110 through the oil leakage port 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 are downward, so as to prevent the oil from flowing along the first baffle 151 to the air intake port 111, and prevent the oil from flowing along the second baffle 152 to the oil leakage port 112.

[0089] The air 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 air intake port 111. The oil leakage 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 oil leakage port 112.

[0090] Combine Figure 1 、 Figure 2 and Figure 8 As shown, in some embodiments, optionally, the shell 110 includes an upper shell 164 and a lower shell 165, the air outlet pipe 114 is arranged on the upper shell 164, the air intake and oil leakage ports are arranged on the lower shell 165, the upper shell 164 is provided with a slot 166, and the lower shell 165 is provided with a plug-in portion 167, and the plug-in portion 167 is plugged into the slot 166.

[0091] The shell 110 is a split structure, that is, the shell 110 includes an upper shell 164 and a lower shell 165. The upper shell 164 and the lower shell 165 are connected by plugging. Setting the shell 110 as a split structure can facilitate the arrangement of the partition 130 and the intake pipe 113 in the shell 110.

[0092] In this solution, a slot 166 is provided on the upper shell 164 and a plug-in portion 167 is provided on the lower shell 165. When the muffler 100 is in use, the opening of the slot 166 faces downward. Even if oil flows along the side of the shell 110 to the joint between the upper shell 164 and the lower shell 165, the oil will not flow into the slot 166, thereby avoiding the accumulation of oil in the slot 166.

[0093] In an embodiment of the present invention, an anti-oil suction muffler structure and a compressor having the same are disclosed. The suction muffler 100 for the compressor includes: an upper shell 164, a lower shell 165, and an integrated partition and a pipe. The upper shell 164 is integrated with an outlet pipe 114 and a slot 166 of the muffler 100. The outlet pipe 114 is assembled in the cylinder head of the compressor. The upper surface of the upper shell 164 is set as an arc surface, and the outer edge of the upper surface is provided with an oil-blocking rib 120. The lower shell 165 has an intake port 111. The side wall of the lower shell 165 is provided with a first blocking rib 151 on the outer ring at the intake port 111. The bottom side wall of the lower shell 165 is provided with an oil leakage port 112 and a second blocking rib 152. The lower shell 165 is provided with a plug-in portion 167 corresponding to the slot 166 of the upper shell 164. The partition 130 divides the interior of the silencer 100 into an upper and lower cavity. The partition 130 is provided with a reinforcing rib 132. The partition 130 is provided with a connecting hole 141. The connecting hole 141 is horizontally connected to the side wall of the insert 140. The insert 140 on the partition 130 connects the upper and lower cavities. The insert 140 is coaxial with the exhaust pipe 114. The partition 130 is integrated with an intake pipe 113 through the reinforcing rib 132. The intake pipe 113 is connected to the intake port 111 of the shell. By using the intake silencer 100, the amount of lubricating oil sucked into the silencer 100 and the entire compression cycle system can be greatly reduced. Not only can the oil discharge of the entire machine be reduced, and the risk of oil blockage in the refrigeration system can be reduced, but also the proportion of refrigerant in the compression process can be increased, thereby improving the refrigeration performance of the entire machine. At the same time, the integrated partition and built-in intake pipe structure of the present invention can efficiently utilize the internal space of the compressor to ensure better noise reduction performance.

[0094] Two technical features are added to the lubricating oil flow path, namely: first, the upper surface of the muffler 100 is set to a circular arc surface; second, an oil-blocking rib 120 is set on the outer edge of the upper surface. The above features can prevent the lubricating oil from flowing toward the air intake 111 and being sucked into the interior of the muffler 100.

[0095] The diameter of the communicating hole 141 is 1 mm to 2 mm, which is conducive to the discharge of accumulated oil without causing leakage in the upper and lower chambers, thereby reducing the silencing capability.

[0096] In an embodiment of the present invention, a compressor is proposed, which includes the muffler in any of the above embodiments and can achieve the same technical effects, which will not be described in detail here.

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

[0098] In an embodiment of the present invention, a refrigerator is proposed, which includes the compressor in the above embodiment and can achieve the same technical effect, which will not be described in detail here.
