Description

Technical Field

[0001] The present invention belongs to the technical field of compressors, and more particularly, relates to a housing assembly, a compressor, and a refrigeration device. Background Art

[0002] In related art compressors, as Figure 1 shown, the motor rotates and is connected to a piston through a crankshaft, a connecting rod, and a piston pin, causing the piston to reciprocate in the cylinder, thereby completing the compression and exhaust working processes. Among them, the lubrication of the core moving parts mainly depends on the crankshaft driving the liquid suction pipe 20' to rotate for oiling, and the bottom end of the liquid suction pipe 20' extends into the lubricating oil in the lower housing 14'. However, the current compressor lubricating oil has low lubrication efficiency and poor lubrication effect, which will cause wear of each moving part and shorten the service life of the compressor. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a housing assembly.

[0005] A second aspect of the present invention provides a compressor.

[0006] A third aspect of the present invention provides a refrigeration device.

[0007] In view of this, according to a first aspect of the present invention, there is provided a housing assembly for a compressor, the housing assembly including: a lower housing, the interior of which can be filled with a lubricating liquid; and a lower housing accessory, which includes a flow disturbing member disposed on the bottom wall of the lower housing.

[0008] In the housing assembly provided by the present invention, by filling the interior of the lower housing with a lubricating liquid, it is beneficial to lubricate the compressor core disposed within the housing assembly. By providing a lower housing accessory on the bottom wall of the lower housing, the lower housing accessory includes a flow disturbing member, and the arrangement of the flow disturbing member is beneficial to disturbing the flow of the lubricating liquid. Especially when the lubricating liquid rotates under the action of centrifugal force, the generated vortex will cause the liquid level of the lubricating liquid to decrease, thereby affecting the suction volume of the liquid suction pipe. However, by disturbing the vortex of the lubricating liquid with the flow disturbing member, the decrease of the liquid level of the lubricating liquid can be effectively prevented, so that the lubricating liquid can remain relatively stable, increasing the amount of the lubricating liquid sucked into the liquid suction pipe of the compressor, improving the lubrication efficiency of the lubricating liquid, and thus improving the lubrication effect.

[0009] In addition, according to the housing assembly provided by the above technical solution of the present invention, the following additional technical features may further be provided:

[0010] In the above technical solution, preferably, the area of the lower housing vertically opposite to the liquid suction pipe of the compressor is the first area; the flow disturbing member is disposed on the bottom wall of the lower housing deviating from the center of the first area.

[0011] In this technical solution, the area of the lower housing vertically opposite to the liquid suction pipe of the compressor is set as the first area. Since the liquid suction pipe rotates, centrifugal force is generated to suck in the lubricating liquid, and eddy currents will appear in the area of the lubricating liquid corresponding to the liquid suction pipe. By disposing the flow disturbing member on the bottom wall of the lower housing deviating from the center of the first area, the eddy currents of the lubricating liquid can be better disturbed, making the liquid level of the lubricating liquid relatively stable, ensuring that the lubricating liquid can be better sucked into the liquid suction pipe, and improving the lubrication effect and efficiency. Preferably, the flow disturbing member is disposed on the bottom wall of the lower housing avoiding the first area.

[0012] In any of the above technical solutions, preferably, the flow disturbing member is a liquid retaining protrusion, and the liquid retaining protrusion extends in a direction away from the bottom wall of the lower housing.

[0013] In this technical solution, setting the flow disturbing member as a liquid retaining protrusion and setting the liquid retaining protrusion to extend in a direction away from the bottom wall of the lower housing can better disturb the eddy currents of the lubricating liquid, prevent the liquid level of the lubricating liquid from dropping significantly, keep the lubricating liquid relatively stable, increase the amount of the lubricating liquid sucked into the liquid suction pipe of the compressor, improve the lubrication efficiency of the lubricating liquid, and thus improve the lubrication effect.

[0014] In any of the above technical solutions, preferably, the liquid retaining protrusion is located on one side of the liquid suction pipe. Further, the liquid retaining protrusion extends at least to the height of the lower end face of the liquid suction pipe of the compressor.

[0015] In this technical solution, by setting the liquid retaining protrusion on one side of the liquid suction pipe, compared with setting the liquid retaining protrusion directly below the liquid suction pipe, the eddy currents can be better blocked, preventing the liquid level of the lubricating liquid from dropping significantly. Further, setting the liquid retaining protrusion to extend at least to the height of the lower end face of the liquid suction pipe of the compressor has a better effect of blocking the eddy currents.

[0016] In any of the above technical solutions, preferably, the lower housing further includes: a filter member disposed on the bottom wall of the lower housing.

[0017] In this technical solution, by disposing the filter member on the bottom wall of the lower housing, it is beneficial to filter impurities such as iron filings falling into the lubricating liquid, ensuring that the impurities do not enter the movement mechanism of the compressor along with the lubricating liquid, preventing wear of the moving parts of the compressor due to the presence of impurities, and increasing the service life of the compressor.

[0018] In any of the above technical solutions, preferably, the flow disturbing member is disposed on the filter member, and the flow disturbing member is disposed on the bottom wall of the lower housing through the filter member.

[0019] In this technical solution, when the lower housing accessory includes a filter element and a spoiler, by arranging the spoiler on the filter element, on the one hand, it can prevent the spoiler from interfering with impurities entering the gap between the filter element and the bottom wall of the lower housing, and on the other hand, it increases the height where the spoiler is located, so that the spoiler can better hinder the flow of the lubricating fluid.

[0020] Of course, the spoiler can also be directly arranged on the bottom wall of the lower housing.

[0021] In any of the above technical solutions, preferably, the spoiler and the filter element are integrally formed, or the spoiler and the filter element are of a split structure.

[0022] In this technical solution, when the lower housing accessory includes a filter element and a spoiler, the spoiler can be integrally formed with the filter element, or the spoiler and the filter element can be of a split structure, which can be set accordingly according to needs.

[0023] In any of the above technical solutions, preferably, the filter element is a slag retaining plate, and there is a gap between at least a part of the lower surface of the filter element and the bottom wall of the lower housing, and the lubricating fluid can flow through the gap.

[0024] In this technical solution, by setting the filter element as a slag retaining plate, there is a gap between at least a part of the lower surface of the filter element and the bottom wall of the lower housing, and ensuring that the lubricating fluid can flow through this gap, when the lubricating fluid flows, it can carry impurities such as iron filings into this gap, and the impurities are stuck or deposited in this gap. Blocked by the filter element, it can effectively reduce the probability of impurities entering the compressor core with the lubricating fluid, and avoid wear of the moving parts of the compressor due to the presence of impurities. In this application, it is default that the lubricating fluid will not penetrate the slag retaining plate and enter the liquid suction pipe. By setting the filter element as a slag retaining plate, the disc-shaped structure is conducive to forming a circumferentially distributed gap, which is conducive to impurities entering the gap from multiple directions. Among them, the slag retaining plate can be a disc or a square plate.

[0025] Of course, the filter element can also be a filter net. In this case, the lubricating fluid passes through the filter net and enters the liquid suction pipe, and the impurities are retained on the other side of the filter net. In this case, the filter net can be arranged at the inlet of the liquid suction pipe.

[0026] In any of the above technical solutions, preferably, the bottom wall of the lower housing includes an arc-shaped wall that is concave in the middle, and the filter element covers the lowest point of the arc-shaped wall and is arranged on the bottom wall of the lower housing.

[0027] In this technical solution, the bottom wall of the lower housing may include an arc-shaped wall that is concave in the middle. By arranging the filter element to cover the lowest point of the arc-shaped wall on the bottom wall of the lower housing, due to the existence of the lowest point of the arc-shaped wall, impurities such as iron filings can move better in the direction of the lowest point under the action of their own gravity, and move towards the area covered by the filter element, thus facilitating the impurities to flow into the gap. Blocked by the filter element, the probability of impurities entering the interior of the compressor core along with the lubricating fluid is effectively reduced.

[0028] Of course, the bottom wall of the lower housing can also be a horizontal wall surface, etc. In this case, the impurities can enter the interior of the gap along with the lubricating fluid under the action of centrifugal force.

[0029] In any of the above technical solutions, preferably, the area of the lower housing that is vertically opposite to the liquid suction pipe of the compressor is the first area; the filter element covers the first area and is arranged on the bottom wall of the lower housing.

[0030] In this technical solution, it is set that the area of the lower housing that is vertically opposite to the liquid suction pipe of the compressor is the first area. Since the liquid suction pipe rotates and generates centrifugal force to suck in the lubricating fluid, a vortex will appear in the area of the lubricating fluid corresponding to the liquid suction pipe. By arranging the filter element to cover the first area on the bottom wall of the lower housing, when the impurities move along with the flow of the lubricating fluid, they will move in the direction of the first area under the action of centrifugal force. Since the filter element covers the first area, it is further conducive to the impurities entering the area covered by the filter element, and is conducive to the impurities entering the gap. Blocked by the filter element, the probability of impurities entering the interior of the compressor core along with the lubricating fluid is effectively reduced.

[0031] In any of the above technical solutions, preferably, the gap is circumferentially distributed around the center line of the liquid suction pipe.

[0032] In this technical solution, by setting the gap to be circumferentially distributed around the center line of the liquid suction pipe, it is conducive to the impurities entering the interior of the gap from multiple directions under the action of centrifugal force, avoiding a large amount of impurities entering the compressor core along with the lubricating fluid because they cannot enter the interior of the gap, thus causing wear of the moving parts of the compressor. Among them, the gap can be a regularly annularly distributed gap or an irregular gap distributed around the center line of the liquid suction pipe for one week.

[0033] In any of the above technical solutions, preferably, the gap is circumferentially distributed around the vertical line passing through the lowest point of the bottom wall of the lower housing.

[0034] In this technical solution, a perpendicular line is drawn through the lowest point of the bottom wall of the lower housing, and the set clearance is circumferentially distributed around this perpendicular line. This is conducive to impurities entering the interior of the clearance from multiple directions under the action of their own gravity, avoiding a large amount of impurities from entering the compressor's movement mechanism along with the lubricating fluid due to their inability to enter the interior of the clearance, thereby causing wear of the various moving parts of the compressor. Among them, the clearance can be a regularly annularly distributed clearance or an irregular clearance that circumferentially distributes around the center line of the liquid suction pipe for one week. Preferably, the clearance is circumferentially distributed both around the perpendicular line passing through the lowest point of the bottom wall of the lower housing and around the center line of the liquid suction pipe.

[0035] In any of the above technical solutions, preferably, the lowest point of the filter element is connected to the lowest point of the bottom wall of the lower housing.

[0036] In this technical solution, when a filter element is included in the vicinity of the lower housing, by setting the lowest point of the filter element to be connected to the lowest point of the bottom wall of the lower housing, a clearance can exist between the lower surface of the filter element that is not connected to the lower housing and the lower housing, which is conducive to impurities such as iron filings better entering the interior of the clearance. Preferably, the filter element is welded to the lower housing, which is convenient and fast to process and has a firm connection.

[0037] In any of the above technical solutions, preferably, the opening size of the clearance in the vertical direction gradually decreases or gradually increases from the direction where the edge of the filter element is located to the interior direction of the filter element.

[0038] In this technical solution, by setting the opening size of the clearance in the vertical direction to gradually decrease from the direction where the edge of the filter element is located to the interior direction of the filter element, it is conducive to impurities getting stuck inside the clearance as the clearance opening gradually decreases during the process of entering the clearance, thereby effectively avoiding impurities from flowing out of the clearance along with the lubricating fluid and entering the interior of the compressor's movement mechanism. By setting the opening size of the clearance in the vertical direction to gradually increase from the direction where the edge of the filter element is located to the interior direction of the filter element, it is conducive to preventing impurities from being removed from the clearance along with the lubricating fluid after the impurities enter the clearance, ensuring that the impurities do not enter the interior of the compressor's movement mechanism along with the lubricating fluid, and avoiding wear of the various moving parts of the compressor due to the presence of impurities.

[0039] In any of the above technical solutions, preferably, the lower surface of the filter element includes a middle concave arc surface, and the bending radian of the arc surface is greater than the bending radian of the arc wall.

[0040] In this technical solution, by setting the lower surface of the filter element to include a middle concave arc surface, and the bending radian of the arc surface is greater than the bending radian of the arc wall, it is conducive to leaving a clearance between the filter element and the bottom wall of the lower housing after the filter element is arranged on the bottom wall of the lower housing.

[0041] In any of the above technical solutions, preferably, the housing assembly further comprises: an upper housing connected to the lower housing to enclose a receiving cavity for receiving a movement of the compressor.

[0042] A second aspect of the present invention provides a compressor, comprising: a shell assembly as described in any one of the above technical solutions.

[0043] The compressor provided by the present invention has a shell assembly according to any of the above technical solutions, and thus has the beneficial effects of any of the above technical solutions, which will not be described in detail here.

[0044] Furthermore, the compressor further comprises: a driving member and a liquid suction pipe, one end of the liquid suction pipe is connected to the driving member and can rotate under the driving action of the driving member, and the other end of the liquid suction pipe can extend below the liquid level of the lubricating liquid. The driving member can be a crankshaft, which is driven by the motor of the compressor to rotate the crankshaft, and then the crankshaft drives the liquid suction pipe to rotate.

[0045] Specifically, during the operation of the compressor, the rotation of the motor drives the crankshaft to rotate, and then drives the piston to reciprocate in the cylinder. The suction pipe can rotate and generate centrifugal force under the rotation of the crankshaft. The lubricating liquid will be sucked into the suction pipe under the action of the centrifugal force, and then flow to the crankshaft, connecting rod, etc. through the suction pipe to fully lubricate the compressor. By arranging a filter and / or a spoiler on the bottom wall of the lower shell, on the one hand, the presence of the filter can prevent impurities in the lubricating liquid from entering between the moving parts of the compressor with the lubricating liquid and affecting the operation of the moving parts. On the other hand, the presence of the spoiler is conducive to reducing the liquid level height lowered by the centrifugal force, so that the suction pipe can suck enough lubricating liquid per unit time to ensure the lubrication efficiency and lubrication effect of the lubricating liquid.

[0046] A third aspect of the present invention provides a refrigeration device, comprising: a compressor as described in any one of the above technical solutions.

[0047] The refrigeration device provided by the present invention has the compressor of any of the above technical solutions, and thus has the beneficial effects of any of the above technical solutions, which will not be described in detail here. The refrigeration device can be a refrigerator or an air conditioner.

[0058] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0059] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0060] Next, refer to Figures 2 to 4 Describe the housing assembly and the compressor according to some embodiments of the present invention.

[0061] As Figure 2 and Figure 3 shown, a first aspect of the present invention provides a housing assembly for a compressor. The housing assembly includes: a lower housing 14, the interior of the lower housing 14 can be filled with lubricating liquid; a lower housing attachment 16, which includes a filter element 162 and / or a spoiler 164, wherein the spoiler 164 is directly or indirectly disposed on the bottom wall of the lower housing 14.

[0062] The housing assembly proposed by the present invention is filled with lubricating fluid inside the lower housing 14, which is beneficial to lubricating the core of the compressor provided in the housing assembly. By providing a lower housing accessory 16 on the bottom wall of the lower housing 14, when the lower housing accessory 16 includes a flow disturbing member 164, the setting of the flow disturbing member 164 is beneficial to disturbing the flow of the lubricating fluid. Especially when the lubricating fluid rotates under the action of centrifugal force, the generated vortex will lower the liquid level of the lubricating fluid, thereby affecting the suction volume of the suction pipe 20. By disturbing the vortex of the lubricating fluid through the flow disturbing member 164, the liquid level of the lubricating fluid can be effectively prevented from decreasing, so that the lubricating fluid can remain relatively stable, increasing the amount of lubricating fluid sucked into the suction pipe 20 of the compressor, improving the lubrication efficiency of the lubricating fluid, and thus improving the lubrication effect.

[0063] Of course, when the housing assembly includes a filter member 162, the setting of the filter member 162 is beneficial to filtering impurities such as iron filings falling into the lubricating fluid, ensuring that the impurities do not enter the core of the compressor along with the lubricating fluid, avoiding wear of the moving parts of the compressor due to the presence of impurities, and increasing the service life of the compressor.

[0064] In some embodiments, as Figure 4 shown, the area of the lower housing 14 vertically opposite to the suction pipe 20 of the compressor is the first area; the flow disturbing member 164 is arranged on the bottom wall of the lower housing 14 deviating from the center of the first area.

[0065] In this embodiment, the area of the lower housing 14 vertically opposite to the suction pipe 20 of the compressor is set as the first area. Since the suction pipe 20 rotates to generate centrifugal force to suck the lubricating fluid, a vortex will appear in the area of the lubricating fluid corresponding to the suction pipe 20. When the lower housing accessory 16 includes a flow disturbing member 164, by arranging the flow disturbing member 164 on the bottom wall of the lower housing 14 deviating from the center of the first area, the vortex of the lubricating fluid can be better disturbed, making the liquid level of the lubricating fluid relatively stable, ensuring that the lubricating fluid can be better sucked by the suction pipe 20, and improving the lubrication effect and efficiency. Preferably, the flow disturbing member 164 is arranged on the bottom wall of the lower housing 14 avoiding the first area.

[0066] In some embodiments, as Figure 3 and Figure 4 shown, the flow disturbing member 164 is a liquid blocking protrusion, and the liquid blocking protrusion extends in a direction away from the bottom wall of the lower housing 14.

[0067] In this embodiment, the spoiler 164 is set as a liquid-blocking protrusion, and the liquid-blocking protrusion extends in a direction away from the bottom wall of the lower housing 14, which can better interfere with the eddy current of the lubricating liquid, avoid a large reduction in the liquid level of the lubricating liquid, keep the lubricating liquid relatively stable, increase the amount of lubricating liquid sucked into the liquid suction pipe 20 of the compressor, improve the lubrication efficiency of the lubricating liquid, and thus improve the lubrication effect. Among them, the liquid-blocking protrusion extending in a direction away from the bottom wall of the lower housing 14 can extend vertically or obliquely.

[0068] In some embodiments, as Figure 4 shown, the liquid-blocking protrusion is located on one side of the liquid suction pipe 20. Further, the liquid-blocking protrusion extends at least to the height where the lower end surface of the liquid suction pipe 20 of the compressor is located.

[0069] In this embodiment, by setting the liquid-blocking protrusion on one side of the liquid suction pipe 20, compared with setting the liquid-blocking protrusion directly below the liquid suction pipe 20, it can better hinder the eddy current and avoid a large reduction in the liquid level of the lubricating liquid. Further, setting the liquid-blocking protrusion to extend at least to the height where the lower end surface of the liquid suction pipe 20 of the compressor is located has a better effect of hindering the eddy current.

[0070] In some embodiments, the lower housing accessory further includes: a filter element 162 disposed on the bottom wall of the lower housing 14.

[0071] In this embodiment, by providing the filter element 162 on the bottom wall of the lower housing 14, it is beneficial to filter impurities such as iron filings falling into the lubricating liquid, ensure that the impurities do not enter the movement mechanism of the compressor along with the lubricating liquid, avoid wear of the moving parts of the compressor due to the presence of impurities, and improve the service life of the compressor.

[0072] In some embodiments, as Figures 2 to 4 shown, the spoiler 164 is disposed on the filter element 162, and the spoiler 164 is disposed on the bottom wall of the lower housing 14 through the filter element 162.

[0073] In this embodiment, when the lower housing accessory 16 includes the filter element 162 and the spoiler 164, by disposing the spoiler 164 on the filter element 162, on the one hand, it can prevent the spoiler 164 from interfering with the entry of impurities into the gap 18 between the filter element 162 and the bottom wall of the lower housing 14, and on the other hand, it increases the height of the spoiler 164, so that the spoiler 164 can better hinder the flow of the lubricating liquid.

[0074] Of course, the spoiler 164 can also be directly disposed on the bottom wall of the lower housing 14.

[0075] In some embodiments, the spoiler 164 and the filter element 162 are integrally formed, or the spoiler 164 and the filter element 162 are of a split structure.

[0076] In this embodiment, when the lower housing accessory 16 includes a filter member 162 and a spoiler member 164, the spoiler member 164 can be integrally formed with the filter member 162, or the spoiler member 164 can be a split structure with the filter member 162, and corresponding settings can be made according to needs.

[0077] In some embodiments, as Figure 3 shown, the filter member 162 is a slag baffle, and there is a gap 18 between at least a part of the lower surface of the filter member 162 and the bottom wall of the lower housing 14, and the lubricating fluid can flow through the gap 18.

[0078] In this embodiment, when the filter member 162 is arranged on the bottom wall of the lower housing 14, by setting the filter member 162 as a slag baffle, there is a gap 18 between at least a part of the lower surface of the filter member 162 and the bottom wall of the lower housing 14, and it is ensured that the lubricating fluid can flow through this gap 18, so that during the flow of the lubricating fluid, iron filings and other impurities can be carried into the gap 18, and the impurities are stuck or deposited in the gap 18. Blocked by the filter member 162, the probability of impurities entering the compressor core with the lubricating fluid can be effectively reduced, and wear of each moving part of the compressor due to the presence of impurities can be avoided. In this application, it is default that the lubricating fluid does not penetrate the slag baffle and enter the liquid suction pipe 20. By setting the filter member 162 as a slag baffle, the disc-shaped structure is conducive to forming a circumferentially distributed gap 18, which is conducive to impurities entering the gap 18 from multiple directions. Among them, the slag baffle can be a disc or a square disc.

[0079] Of course, the filter member 162 can also be a filter net. In this case, the lubricating fluid passes through the filter net and enters the liquid suction pipe 20, and the impurities are retained on the other side of the filter net. In this case, the filter net can be arranged at the entrance of the liquid suction pipe 20.

[0080] In some embodiments, as Figure 3 shown, the bottom wall of the lower housing 14 includes an arc-shaped wall that is concave in the middle, and the filter member 162 covers the lowest point of the arc-shaped wall and is arranged on the bottom wall of the lower housing 14.

[0081] In this embodiment, the bottom wall of the lower housing 14 can include an arc-shaped wall that is concave in the middle. By setting the filter member 162 to cover the lowest point of the arc-shaped wall and be arranged on the bottom wall of the lower housing 14, due to the existence of the lowest point of the arc-shaped wall, iron filings and other impurities can move better in the direction of the lowest point under the action of their own gravity, and move towards the area covered by the filter member 162, which is conducive to impurities flowing into the gap 18. Blocked by the filter member 162, the probability of impurities entering the compressor core with the lubricating fluid is effectively reduced.

[0082] Of course, the bottom wall of the lower housing 14 can also be a horizontal wall surface, etc. In this case, the impurities can enter the gap 18 with the lubricating fluid under the action of centrifugal force.

[0083] In some embodiments, as Figure 4 shown, the area of the lower housing 14 vertically opposite to the liquid suction pipe 20 of the compressor is the first area; the filter element 162 is disposed on the bottom wall of the lower housing 14 to cover the first area.

[0084] In this embodiment, the area of the lower housing 14 vertically opposite to the liquid suction pipe 20 of the compressor is set as the first area. Since the liquid suction pipe 20 rotates to generate a centrifugal force to suck the lubricating liquid, a vortex will appear in the area corresponding to the liquid suction pipe 20 of the lubricating liquid. By disposing the filter element 162 on the bottom wall of the lower housing 14 to cover the first area, when the impurities move along with the flow of the lubricating liquid, they will move in the direction of the first area under the action of the centrifugal force. Since the filter element 162 covers the first area, it is beneficial for the impurities to enter the area covered by the filter element 162 and beneficial for the impurities to enter the gap 18. Blocked by the filter element 162, the probability of impurities entering the compressor movement mechanism along with the lubricating liquid is effectively reduced.

[0085] In some embodiments, as Figure 4 shown, the gap 18 is circumferentially distributed around the center line of the liquid suction pipe 20.

[0086] In this embodiment, by setting the gap 18 to be circumferentially distributed around the center line of the liquid suction pipe 20, it is beneficial for the impurities to enter the inside of the gap 18 from multiple directions under the action of the centrifugal force, avoiding a large amount of impurities from entering the movement mechanism of the compressor along with the lubricating liquid due to being unable to enter the inside of the gap 18, thereby causing wear of the moving parts of the compressor. Among them, the gap 18 can be a regularly annularly distributed gap 18 or an irregularly distributed gap 18 around the center line of the liquid suction pipe 20 for one week.

[0087] In some embodiments, as Figure 3 and Figure 4 shown, the gap 18 is circumferentially distributed around the vertical line passing through the lowest point of the bottom wall of the lower housing 14.

[0088] In this embodiment, a vertical line is drawn through the lowest point of the bottom wall of the lower housing 14. By setting the gap 18 to be circumferentially distributed around the vertical line, it is beneficial for the impurities to enter the inside of the gap 18 from multiple directions under the action of their own gravity, avoiding a large amount of impurities from entering the movement mechanism of the compressor along with the lubricating liquid due to being unable to enter the inside of the gap 18, thereby causing wear of the moving parts of the compressor. Among them, the gap 18 can be a regularly annularly distributed gap 18 or an irregularly distributed gap 18 around the center line of the liquid suction pipe 20 for one week. Preferably, the gap 18 is circumferentially distributed around both the vertical line passing through the lowest point of the bottom wall of the lower housing 14 and the center line of the liquid suction pipe 20.

[0089] In some embodiments, as Figure 3As shown, the lowest point of the filter element 162 is connected to the lowest point of the bottom wall of the lower shell 14.

[0090] In this embodiment, when the lower housing attachment 16 includes a filter 162, the lowest point of the filter 162 is connected to the lowest point of the bottom wall of the lower housing 14, so that a gap 18 can exist between the lower surface of the filter 162 that is not connected to the lower housing 14 and the lower housing 14, which is conducive to better entry of impurities such as iron filings into the gap 18. Preferably, the filter 162 is welded to the lower housing 14, which is convenient and fast to process and has a stable connection.

[0091] In some embodiments, Figure 3 As shown, the vertical opening size of the gap 18 gradually decreases or increases from the edge of the filter element 162 to the inside of the filter element 162 .

[0092] In this embodiment, by setting the vertical opening size of the gap 18 to gradually decrease from the direction of the edge of the filter 162 to the inside of the filter 162, it is beneficial for impurities to be stuck inside the gap 18 as the opening of the gap 18 gradually decreases during the process of entering the gap 18, thereby effectively preventing impurities from flowing out of the gap 18 with the lubricating fluid and entering the compressor movement. By setting the vertical opening size of the gap 18 to gradually increase from the direction of the edge of the filter 162 to the inside of the filter 162, it is beneficial for impurities to enter the gap 18 after entering the gap 18. Since the opening of the gap 18 is smaller near the edge of the filter 162, it is effective to prevent impurities from moving out of the gap 18 with the lubricating fluid, ensuring that impurities will not enter the compressor movement with the lubricating fluid, and avoiding wear of the moving parts of the compressor due to the presence of impurities.

[0093] In some embodiments, Figure 3 As shown, the lower surface of the filter element 162 includes an arc-shaped surface with a concave middle portion, and the curvature of the arc-shaped surface is greater than the curvature of the arc-shaped wall.

[0094] In this embodiment, by setting the lower surface of the filter element 162 to include an arc-shaped surface with a concave middle portion, the curvature of the arc-shaped surface is greater than the curvature of the arc-shaped wall, which is beneficial for leaving a gap 18 between the filter element 162 and the bottom wall of the lower shell 14 after the filter element 162 is set on the bottom wall of the lower shell 14.

[0095] In some embodiments, Figure 4 As shown, the housing assembly further includes: an upper housing 12, which is connected to a lower housing 14 to enclose a receiving cavity. The receiving cavity is used to receive the movement of the compressor.

[0096] like Figure 4 As shown, a second aspect of the present invention provides a compressor, comprising: a shell assembly as described in any one of the above embodiments.

[0097] The compressor provided by the present invention has the beneficial effects of any of the above embodiments due to having the housing assembly of any of the above embodiments, and will not be elaborated here one by one.

[0098] Further, the compressor further includes: a driving member and a liquid suction pipe 20. One end of the liquid suction pipe 20 is connected to the driving member and can rotate under the driving action of the driving member. The other end of the liquid suction pipe 20 can extend below the liquid level of the lubricating liquid. Here, it is defaulted that when the lubricating liquid is filled in the lower housing, the liquid suction pipe will surely extend into the lubricating liquid to facilitate lubrication. Among them, the driving member can be a crankshaft. The crankshaft is driven to rotate by the motor of the compressor, and then the liquid suction pipe 20 is driven to rotate by the crankshaft.

[0099] Specifically, during the operation of the compressor, the motor rotates to drive the crankshaft to rotate, and then drives the piston to reciprocate in the cylinder. The liquid suction pipe 20 can rotate under the rotation of the crankshaft and generate centrifugal force. The lubricating liquid will be sucked into the liquid suction pipe 20 under the action of the centrifugal force, and thus flow to the crankshaft, connecting rod, etc. through the liquid suction pipe 20 to fully lubricate the compressor. By providing a filter member 162 and / or a flow disturbing member 164 on the bottom wall of the lower housing 14, on the one hand, the presence of the filter member 162 can prevent impurities in the lubricating liquid from entering between the moving parts of the compressor along with the lubricating liquid and affecting the operation of the moving parts. On the other hand, the presence of the flow disturbing member 164 is beneficial to reducing the liquid level height reduced by the centrifugal force, so that the liquid suction pipe 20 can suck enough lubricating liquid per unit time to ensure the lubrication efficiency and lubrication effect of the lubricating liquid.

[0100] The third aspect embodiment of the present invention provides a refrigeration device, including: a compressor as described in any one of the above embodiments.

[0101] The refrigeration device provided by the present invention has the beneficial effects of any of the above embodiments due to having the compressor of any of the above embodiments, and will not be elaborated here one by one. Among them, the refrigeration device can be a refrigerator or an air conditioner.
