Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a compressor according to an embodiment of the present invention, and as shown in fig. 1, the compressor includes: the oil-mist separator comprises a shell 10, a main frame 20, a motor 30 and an oil ring 40, wherein the shell 10 comprises an accommodating cavity 11, the main frame 20, the motor 30 and the oil ring 40 are all arranged in the accommodating cavity 11, the oil ring 40 is positioned between the motor 30 and the main frame 20, and a first bulge 41 for separating oil mist is arranged on the inner wall of the oil ring 40.

The compressor may further include a compression pump, the compression pump may be used for compressing refrigerant gas (for example, the refrigerant gas may be oil mist in the present embodiment), and the motor 30 may be used for driving the compression pump to work, for example: the motor 30 may drive the compression pump to operate by the drive shaft, and the main frame 20 may be used to fix the drive shaft.

The working principle of the embodiment of the invention can be expressed as follows:

the oil mist can pass through the inner wall of the oil ring 40 and contact the first protrusion 41 on the inner wall of the oil ring 40, so that the flow speed of the oil mist is reduced due to the blocking effect of the first protrusion 41 and the inner wall of the oil ring 40 on the oil mist, so that the oil contained in the oil mist can be easily separated from the oil mist and can slide down along the inner wall of the oil ring 40. Thus, the oil mist separation function is achieved, thereby reducing an Oil Circulation Rate (OCR) of the compressor. It should be noted that, since the first protrusion 41 is provided on the inner wall of the oil ring 40, it can be understood that the surface area of the inner wall of the oil ring 40 is correspondingly increased, that is, the area contacting with the oil mist is increased, and the separation effect on the oil mist can also be enhanced.

The oil mist in the present embodiment may also be referred to as a refrigerant, and is mainly used to transfer heat energy and generate a refrigeration effect.

The specific shape of the first protrusion 41 is not limited herein, and for example: the first protrusion 41 may be a triangular protrusion, a rectangular protrusion, an arc-shaped protrusion, or the like. It should be noted that, as an alternative embodiment, the number of the first protrusions 41 may be multiple, and a connection line connecting the highest point positions of the multiple first protrusions 41 may be in a wave shape. Of course, as another alternative embodiment, each first protrusion 41 may also be a wave-shaped protrusion.

It should be noted that, referring to fig. 2, fig. 2 can be understood as a top view of fig. 1, the compressor may further include an upper balance weight 50 and a lower balance weight, and the upper balance weight 50 or the lower balance weight may rotate the oil mist, so that the oil mist may collide with the inner wall of the oil ring 40, and the oil in the oil mist may be separated from the oil mist more easily. Referring to fig. 2, the upper balance mass 50 rotates in the direction indicated by C in fig. 2, and the oil mist rotates in the direction indicated by D in fig. 2.

Optionally, referring to fig. 4, a second protrusion 411 is disposed on the first protrusion 41.

The specific type of the second protrusion 411 is not limited herein, for example: the second protrusion 411 may be a cylindrical protrusion or a circular arc protrusion. In addition, the second protrusion 411 may also be made of plastic or metal.

As an alternative embodiment, the second protrusion 411 may be disposed along the flow direction of the oil mist in the oil ring 40, for example: the oil mist moves in the radial direction of the oil ring 40, and the second projection 411 may also be provided in the radial direction of the oil ring 40; alternatively, the oil mist moves in the axial direction of the oil ring 40, and the second projection 411 may also be provided in the axial direction of the oil ring 40.

In addition, as another alternative embodiment, the direction of the second protrusion 411 may also intersect the flow direction of the oil mist in the oil ring 40. For example: the oil mist moves in the radial direction of the oil ring 40, and the second projection 411 may also be provided in the axial direction of the oil ring 40, and the second projection 411 is provided in the direction perpendicular to the moving direction of the oil mist, so that the separation effect of the oil mist can be further enhanced.

In this embodiment, the second protrusion 411 is disposed on the first protrusion 41, so that the contact area with the oil mist is increased, and the second protrusion 411 can reduce the flow velocity of the oil mist in the oil ring 40, thereby not only further enhancing the separation effect on the oil mist, but also enhancing the connection strength of the first protrusion 41 (i.e., the second protrusion 411 can also function as a reinforcing rib).

Alternatively, the first protrusion 41 is of an integrally formed structure with the inner wall of the oil ring 40. In this case, the first protrusion 41 and the inner wall of the oil ring 40 may be formed by casting or stamping, so as to further enhance the connection strength between the first protrusion 41 and the oil ring 40.

Alternatively, the first protrusion 41 is fixedly connected to an inner wall of the oil ring 40.

As an alternative embodiment, the first protrusion 41 and the inner wall of the oil ring 40 may be fixedly connected by an adhesive.

The adhesive is not limited herein, and for example: the adhesive may be glue or the like, and the first protrusion 41 is fixedly connected to the inner wall of the oil ring 40 by the adhesive, so that the maintenance or position adjustment of the first protrusion 41 is facilitated.

As another alternative embodiment, a clamping groove may be formed on an inner wall of the oil ring 40, and an edge of the first protrusion 41 may be embedded in the clamping groove, so as to fixedly connect the first protrusion 41 and the inner wall of the oil ring 40.

As another alternative, the first protrusion 41 may be fixed to the inner wall of the oil ring 40 by welding, screwing, riveting, or the like.

Therefore, in the machining process, the first bulge 41 and the oil ring 40 can be machined respectively, and then the first bulge 41 and the oil ring 40 are fixedly connected, so that the machining difficulty is reduced, and the machining efficiency is improved.

Wherein, optionally, a third protrusion for separating oil mist is provided on the outer wall of the oil ring 40. The principle of the third protrusion for separating oil mist can be seen in the principle of the first protrusion 41 for separating oil mist, that is, oil mist can collide with the third protrusion, so that the flow speed of oil mist is delayed, and the oil mist is separated.

In addition, for the specific arrangement mode, structure and the like of the third protrusion, reference may be made to the related expression of the first protrusion 41, and details are not described herein.

As an alternative embodiment, referring to fig. 5, the oil ring 40 is a cylindrical oil ring. Of course, as another alternative embodiment, at least one of the inner wall and the outer wall of the oil ring 40 may be disposed in a wave shape, and when both the inner wall and the outer wall of the oil ring 40 are disposed in a wave shape, the oil ring 40 may be referred to as a wave-shaped oil ring. Thus, the versatility of the oil ring 40 is increased.

As another alternative, the oil ring 40 is a radial oil ring. Thus, the oil ring 40 is a radial oil ring, so that the oil mist can be guided.

When the radial oil ring is installed in the compressor, the radial direction of the oil ring can be from the side close to the main frame 20 to the side close to the motor 30, so that the oil mist drainage effect can be further enhanced.

In addition, referring to fig. 3 and 4, as another alternative embodiment, the edge of the oil ring 40 may be further provided with a first connection ring 42 and a second connection ring 43, the first connection ring 42 is located between the oil ring 40 and the second connection ring 43, and the first connection ring 42 may be fixedly connected with the oil ring 40 and the second connection ring 43, respectively. In this way, the oil ring 40, the first connecting ring 42 and the second connecting ring 43 can together form a radial component, which can also drain oil mist.

When the outer wall of the oil ring 40 is in a wave shape, the inner wall and the outer wall of the first connecting ring 42 can be both arc-shaped, the inner wall and the outer wall of the second connecting ring 43 can also be arc-shaped, and the radian of the first connecting ring 42 can be larger than that of the second connecting ring 43, so that the oil ring 40 to the second connecting ring 43 can achieve the effect that the radians can be sequentially decreased, meanwhile, when the oil mist passes through the gap between the outer wall of the oil ring 40 and the inner wall of the housing 10, the first connecting ring 42 and the second connecting ring 43 can achieve the drainage effect on the oil mist, and meanwhile, the first connecting ring 42 and the second connecting ring 43 are further arranged, so that the flow path of the oil mist is prolonged, and the oil circulation rate is further reduced.

As an alternative embodiment, the third protrusion may be in abutment with the inner wall of the housing 10; but there is a connection gap between the position where the third projection is not provided on the outer wall of the oil ring 40 and the inner wall of the housing 10, while the motor 30 may have a first oil mist passage (see the following description for details) between it and the inner wall of the housing 10, and the first oil mist passage communicates with the connection gap, so that the oil mist can move through the connection gap and the first oil mist passage to the side of the motor 30 remote from the oil ring 40, after which the oil mist can simultaneously flow back along the first oil mist passage to a position between the oil ring 40 and the motor 30, and enters an inner cavity enclosed by the inner wall of the oil ring 40 through a gap between the oil ring 40 and the motor 30, or, the oil can enter the inner cavity of the oil ring 40 through a first passage (the first passage can be an air inlet groove) formed on the oil ring 40, of course, the oil ring 40 may also enter the inner cavity through a gap between the oil ring 40 and the main frame. Thus, the flow path of the oil mist is increased, thereby further enhancing the separation effect of the oil mist.

It should be noted that the first oil mist passage through which the oil mist moves from the first position (the position between the outer wall of the oil ring 40 and the inner wall of the housing 10) to the second position (the position on the side of the motor 30 remote from the oil ring 40), and the first oil mist passage through which the oil mist flows back from the second position to the third position (the position between the oil ring 40 and the motor 30) may not be the same passage. For example: a plurality of first oil mist passages, including a first target passage through which oil mist may pass when moving from the first position to the second position and a second target passage through which oil mist may pass when returning from the second position to the third position, may be provided between the outer wall of the motor 30 and the inner wall of the housing 10. The first target passage and the second target passage may be drainage grooves formed in an outer wall of the motor 30 (i.e., an outer wall of the stator 31) (see the description in the following embodiments for specific description).

In addition, when the oil mist is located at a position between the outer wall of the oil ring 40 and the inner wall of the housing 10, the oil mist can also move along the outer wall of the oil ring 40 (although the third projection is in abutment with the inner wall of the housing 10, there is a small amount of clearance through which the oil mist can pass), since the oil ring 40 is provided at a partial position on the outer wall thereof with the third protrusion, and is not provided at a partial position thereof, the distance between the position where the third protrusion is provided and the inner wall of the housing 10, the distance from the position where the third projection is not provided to the inner wall of the housing 10 is not the same, and thus, when the oil mist moves along the outer wall of the oil ring 40, the flow rate of the oil mist passing through the above-described different positions (i.e., the position where the third projection is provided and the position where the third projection is not provided) is different, thereby changing the flow velocity of the oil mist, being beneficial to oil-gas separation in the oil mist and reducing the oil circulation rate.

Optionally, referring to fig. 3 and 4, an inner cavity is defined by an inner wall of the oil ring 40, a first channel 401 is opened on an outer wall of the oil ring 40, and the first channel 401 is communicated with the inner cavity. In this way, oil mist can be facilitated to enter and exit the inner cavity of the oil ring 40 through the first passage 401.

For example: as an alternative embodiment, the oil mist may first enter the cavity of the oil ring 40 (e.g., may enter the cavity through a channel on the main frame 20 or a channel on the motor 30), and may move circumferentially along the inner wall of the oil ring 40 (may collide with the first protrusion 41 for separation), then enter a position between the outer wall of the oil ring 40 and the inner wall of the housing 10 through the first channel 401, and move circumferentially along the outer wall of the oil ring 40, and finally exit the compressor via the compressor discharge pipe 12.

As an alternative embodiment, an inner cavity is defined by an inner wall of the oil ring 40, a second channel 402 is opened on an outer wall of the oil ring 40, and the second channel 402 is communicated with the inner cavity. The exhaust pipe 12 can communicate with the inner cavity of the oil ring 40 through the second passage 402, so that the oil mist can enter the position between the outer wall of the oil ring 40 and the inner wall of the housing 10, and the oil mist can move circularly along the outer wall of the oil ring 40, then enter the inner cavity of the oil ring 40 through the first passage 401, and move circularly along the inner wall of the oil ring 40 under the driving of the upper balance weight 50, and finally exit the compressor through the exhaust pipe 12.

It should be noted that the exhaust pipe 12 and the first passage 401 may be disposed on opposite sides of the oil ring 40, and it may also be understood that an included angle between the exhaust pipe 12 and the first passage 401 is 180 degrees. Thus, the movement path of the oil mist along the outer wall or the inner wall of the oil ring 40 in the circular motion can be increased, and the separation effect on the oil mist can be increased.

The oil mist enters a position between the outer wall of the oil ring 40 and the inner wall of the housing 10, and may collide with the third projection on the outer wall of the oil ring 40, thereby enhancing the oil mist separation effect.

It should be noted that, the first channel 401 and the second channel 402 may be both grooves, and the oil ring 40 may be provided with an avoidance groove of other components, and the avoidance groove may be at least one of the first channel 401 and the second channel 402, that is, the avoidance groove may be multiplexed with the first channel 401 and the second channel 402; of course, the avoiding groove, the first channel 401 and the second channel 402 may be in a separate structure, that is, the oil ring 40 may be provided with the avoiding groove, the first channel 401 and the second channel 402 at the same time. In addition, the first passage 401 and the second passage 402 may be disposed opposite to each other, so that the flow path of the oil mist in the inner cavity of the oil ring 40 can be enlarged. Additionally, an escape slot may be located remotely from the first channel 401 and the second channel 402.

As another alternative, a gap may be provided between the third protrusion and the inner wall of the housing 10, so that the gap may be used for oil mist (the oil mist may be oil mist after separation or oil mist without separation). The difference between this embodiment and the above alternative embodiment is: in this embodiment, the oil mist moves mainly along the outer wall of the oil ring 40 at a position between the outer wall of the oil ring 40 and the inner wall of the housing 10, whereas in the above alternative embodiment, the oil mist moves mainly through the connecting gap and the first oil mist passage to a position on the side of the motor 30 away from the oil ring 40, and then flows back into the inner cavity of the oil ring 40 along the first oil mist passage.

It should be noted that, in the present embodiment, when the first passage 401 is opened on the outer wall of the oil ring 40, and the first passage 401 is communicated with the inner cavity of the oil ring 40, since the oil mist mainly moves along the outer wall of the oil ring 40, the pressure in the inner cavity is different from the pressure between the outer wall of the oil ring 40 and the inner wall of the housing 10, so that the inner cavity can generate a suction force (which may also be referred to as a centrifugal force) to the oil mist through the first passage 401, and the oil is separated from the oil mist.

In addition, the motor 30 includes a stator 31 and a rotor 32, a second oil mist passage may be provided between the stator 31 and the rotor 32, and the specific description of the second oil mist passage may refer to the corresponding description in the subsequent embodiment, and the oil mist located in the inner cavity of the oil ring 40 may pass through the second oil mist passage, reach the position of the motor 30 on the side away from the oil ring 40, then pass through the first oil mist passage between the motor 30 (i.e., the stator 31) and the inner wall of the housing 10, reach the position between the outer wall of the oil ring 40 and the inner wall of the housing 10, and then move along the outer wall of the oil ring 40.

It should be noted that the casing 10 may also be provided with an exhaust pipe 12, and as an alternative embodiment, the exhaust pipe 12 may be communicated with a gap between the outer wall of the oil ring 40 and the inner wall of the casing 10; as another alternative, the exhaust pipe 12 may communicate with the inner cavity of the oil ring 40 through a second passage 402 formed in the outer wall of the oil ring 40. And the separated oil mist can be discharged out of the compressor through the above-mentioned discharge pipe 12.

For example: referring to fig. 1, the separated oil mist can be discharged out of the compressor through the discharge pipe 12 in the direction indicated by a in fig. 1.

In an embodiment of the present invention, a compressor includes: the oil-mist separator comprises a shell 10, a main frame 20, a motor 30 and an oil ring 40, wherein the shell 10 comprises an accommodating cavity 11, the main frame 20, the motor 30 and the oil ring 40 are all arranged in the accommodating cavity 11, the oil ring 40 is positioned between the motor 30 and the main frame 20, and a first bulge 41 for separating oil mist is arranged on the inner wall of the oil ring 40. Thus, since the oil ring 40 is provided with the first projection 41 exclusively for separating oil mist, the oil circulation rate of the compressor can be reduced.

Alternatively, referring to fig. 1 and 2, the motor 30 includes a stator 31 and a rotor 32, the stator 31 is sleeved on the rotor 32, and the stator 31 is at least partially inserted into the oil ring 40.

Wherein, there is magnetic force between the stator 31 and the rotor 32, and under the driving of the magnetic force, the rotor 32 can rotate, and at the same time, the rotor 32 can drive the compression pump to work through the driving shaft (which can rotate with the rotor 32), and the driving shaft can be fixed on the main frame 20.

It should be noted that, the outer wall of the stator 31 may be provided with a drainage groove, so that the oil separated from the oil mist may fall back to the oil groove of the compressor through the drainage groove, thereby achieving the effect of recovering the oil in the oil mist.

Wherein, stator 31 at least partially wears to establish in oil ring 40, can understand: at least a portion of the stator 31 is located within an inner cavity defined by an inner wall of the oil ring 40.

In the embodiment of the present invention, since the motor 30 includes the stator 31 and the rotor 32, the compression pump can be driven to operate better by the magnetic force between the stator 31 and the rotor 32.

Alternatively, referring to fig. 1, the stator 31 includes a coil 311 and a body 312, the coil 311 is disposed in the oil ring 40, and the body 312 is disposed in a staggered manner with respect to the oil ring 40.

The coil 311 may be energized to generate a magnetic field, and the body 312 may be made of silicon steel.

In the embodiment of the present invention, the coil 311 is inserted into the oil ring 40, and the body 312 and the oil ring 40 are disposed in a staggered manner, so that the oil ring 40 can protect the coil 311.

Alternatively, an overlapping region of the outer wall of the coil 311 and the inner wall of the oil ring 40 is provided with an elastic member (not shown in the drawings).

The specific type of the elastic member is not limited herein, for example: the elastic element can be a spring or a rubber pad and the like.

The elastic member may be located in an overlapping region between an inner wall of the oil ring 40 and an outer wall of the coil 311, and between the inner wall of the oil ring 40 and the outer wall of the coil 311.

In this embodiment, since the elastic member is disposed in the overlapping region between the inner wall of the oil ring 40 and the outer wall of the coil 311, the inner wall of the oil ring 40 or the outer wall of the coil 311 can be prevented from being damaged due to friction between the inner wall of the oil ring 40 and the outer wall of the coil 311, and the service lives of the oil ring 40 and the coil 311 are prolonged.

Alternatively, the elastic members abut against the inner wall of the oil ring 40 and the outer wall of the coil 311, respectively. Thus, the strength of connection between the inner wall of the oil ring 40 and the outer wall of the coil 311 can be increased, and at the same time, the fixation of the elastic member can be made more convenient.

Alternatively, a gap through which oil mist passes is provided between an outer wall of the coil 311 and an inner wall of the oil ring 40.

The oil mist can enter the inner cavity surrounded by the inner wall of the oil ring 40 through the gap, and can collide with the inner wall of the oil ring 40 and the first protrusion 41, thereby separating the oil mist.

In the embodiment of the invention, because the gap for oil mist to pass through is arranged between the outer wall of the motor and the inner wall of the oil ring 40, the oil mist can more conveniently enter the inner cavity formed by the enclosing of the inner wall of the oil ring 40, and the oil mist separation effect is further enhanced.

As an alternative embodiment, a first oil mist passage through which oil mist passes is provided between the outer wall of the stator 31 and the inner wall of the housing 10. As another alternative embodiment, a second oil mist passage through which oil mist passes is provided between the inner wall of the stator 31 and the outer wall of the rotor 32.

Thus, the oil mist can enter the inner cavity formed by the inner wall of the oil ring 40 through the first oil mist passage or the second oil mist passage and collide with the inner wall of the oil ring 40 or the first projection 41, thereby separating the oil mist.

It should be noted that the first oil mist passage and the second oil mist passage may be provided at the same time, or may not be provided at the same time. When the first oil mist passage and the second oil mist passage are provided at the same time, referring to fig. 1, the oil mist can move in the direction indicated by B and sequentially pass through the first oil mist passage and the second oil mist passage into an inner cavity defined by the inner wall of the oil ring 40, thereby completing the separation of the oil mist.

It should be noted that, as an alternative embodiment, the outer wall of the stator 31 may abut against the inner wall of the housing 10 (i.e., the outer wall of the stator 31 may be in interference fit with the inner wall of the housing 10), so as to facilitate the fixing of the stator 31. Meanwhile, a drainage groove can be further formed in the outer wall of the stator 31, oil after oil mist separation can flow back to the oil groove of the compressor through the drainage groove, and meanwhile, the drainage groove can also serve as a first oil mist channel through which oil mist (oil mist after separation can be performed, and oil mist which is not subjected to separation) passes in the embodiment. As another alternative, the outer wall of the stator 31 may have a gap with the inner wall of the housing 10, and a fixing protrusion may be provided on the outer wall of the stator 31 and abut against the outer wall of the housing 10, so that the gap between the outer wall of the stator 31 and the inner wall of the housing 10 may serve as the first oil mist passage.

It should be noted that, after the oil mist passes through the first oil mist passage, as an alternative embodiment, the oil mist may enter an inner cavity formed by the inner wall of the oil ring 40 through a gap at the interface between the oil ring 40 and the motor 30 (which may be the coil 311); of course, as another alternative embodiment, after the oil mist passes through the first oil mist channel, the oil mist may also enter the inner cavity formed by the inner wall of the oil ring 40 through the through hole or the avoiding groove formed in the outer wall of the oil ring 40; as another alternative, the first oil mist channel and the second oil mist channel are communicated, so that the oil mist can enter the inner cavity formed by the inner wall of the oil ring 40 through the second oil mist channel after passing through the first oil mist channel, thereby realizing the repeated circulation separation of the oil mist and enhancing the oil mist separation effect.

In addition, the separated oil mist can reenter the inner cavity formed by the inner wall of the oil ring 40 through the first oil mist passage, so that the oil mist separation can be repeatedly performed, and the oil circulation rate in the compressor can be further reduced.

Thus, the versatility and flexibility of the manner in which the oil mist enters the inner cavity defined by the inner wall of the oil ring 40 is increased.

It should be noted that the outer wall of the oil ring 40 may be circular or wavy, and when the outer wall of the oil ring 40 is wavy, the oil mist may collide with the outer wall of the oil ring 40 when passing through the gap between the outer wall of the oil ring 40 and the inner wall of the housing 10, thereby further enhancing the oil mist separation effect.

The embodiment of the invention also provides an air conditioner which comprises the compressor in the embodiment. Since the present embodiment includes the compressor in the above embodiment, the same advantageous technical effects as those of the above embodiment are obtained. The specific structure of the compressor can be referred to the corresponding expressions in the above embodiments, and details are not described herein.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
