The described embodiments are some, but not all, embodiments of the utility model.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model.

For example, an oil for a compressor is provided with a first through hole for refrigerant flow, and a baffle plate extends to the outside of the first through hole at the edge of the first through hole.

In the oil for a compressor according to the present embodiment, the baffle plate extends outward of the first through hole at the edge of the first through hole in the oil, and the oil is applied to the compressor, so that the fluid discharged from the rotor core contacts the baffle plate, and then the refrigerant and the oil are sufficiently separated, thereby improving the oil discharge of the compressor.

Embodiment one:

as shown in fig. 1, in an oil content for a compressor, when a refrigerant containing oil passes through a motor gap and a motor upper space during operation of the compressor, the oil content 1 is used to sufficiently separate the oil from the refrigerant, thereby reducing the amount of oil discharged from the compressor along with the refrigerant and improving the reliability of the compressor and the stability of system performance.

The oil 1 is provided with a first through hole 11 for refrigerant circulation, and a baffle 12 extends to the outside of the first through hole 11 at the edge of the first through hole 11. Here, the baffle plate 12 extends toward the outside of the first through hole 11 at the edge of the first through hole 11, and it is understood that the extending starting point of the baffle plate 12 is the edge of the first through hole 11, and the extending direction of the baffle plate 12 is the direction away from the first through hole 11, rather than the direction extending into the first through hole 11, and may extend vertically upward or downward from the edge of the first through hole 11, or may extend in an upward or downward inclined manner, so that the baffle plate 12 integrally protrudes from the first through hole 11, and thus, the sufficient separation effect of the refrigerant and the oil is achieved.

It should be noted that, in this example, the shape and the number of the first through holes 11 are not limited, and the shape and the number thereof can be adjusted according to actual requirements, so as to meet the refrigerant circulation requirements, for example, the first through holes 11 may be circular holes, quadrangular holes, or waist-shaped holes, and the number thereof may be six, seven, or eight.

It will be appreciated that when the oil 1 is applied to a compressor, the first through hole 11 corresponds to a direction in which the refrigerant is discharged during operation of the compressor, so that the contact between the baffle 12 and the refrigerant is utilized to achieve a sufficient separation effect of the refrigerant and the oil.

The oil structure in the prior art can not fully separate oil and refrigerant, so that more oil is discharged out of the compressor along with the refrigerant, the oil level of the compressor is reduced, and the reliability is affected; meanwhile, the refrigerant oil content in the system is too high, so that the heat exchange effect of the copper pipe is affected, and the system performance is affected; in the oil content 1 structure provided in this example, the baffle plate 12 extends outward of the first through hole 11 at the edge of the first through hole 11 on the oil content 1, and when the oil content 1 is applied to a compressor, the fluid discharged from the rotor core is brought into contact with the baffle plate 12, and then the refrigerant and the oil are sufficiently separated, so that the oil discharge of the compressor is improved, and the system performance and reliability of the compressor are improved.

Embodiment two:

referring to fig. 1, the baffle 12 is vertically connected to the oil 1, and can be in contact with the refrigerant over a large area when the compressor rotates at a high speed, thereby sufficiently separating the oil from the refrigerant and reducing oil discharge.

In this example, the first through hole 11 is a quadrangular hole, and the extending start point of the baffle 12 is one side edge of the first through hole 11, and extends vertically upwards from the side edge, so that the baffle 12 formed finally is perpendicular to the oil 1, and can be contacted with the refrigerant in a larger area when the compressor rotates at a high speed, thereby fully separating the oil from the refrigerant, reducing the oil amount discharged from the compressor along with the refrigerant, and improving the reliability of the compressor and the stability of the system performance.

When this oil 1 is applied, the lower surface of the oil 1 is brought into contact with the upper end surface of the rotor core, and when the baffle 12 is perpendicular to the oil 1, the baffle 12 is perpendicular to the rotor core, so that the baffle 12 having a vertical structure can be brought into contact with the refrigerant over a large area when the compressor rotates at a high speed, and separation of the oil and the refrigerant can be sufficiently performed.

Embodiment III:

referring to fig. 2, the baffle 12 is of an inclined flanging structure and is located above the first through hole 11, so that the fluid can be contacted with the baffle 12 in a large area, and separation of oil and refrigerant can be better realized.

In this example, the baffle plate 12 extends from a part of the edge of the first through hole 11, and extends obliquely upward from the part of the edge, forming a burring structure.

Specifically, the first through hole 11 is a quadrilateral hole, the first through hole 11 includes a first side edge and a second side edge which are in relative relation, the baffle 12 is obliquely turned up upwards from the first side edge of the first through hole 11 and is not in contact with the second side edge, and when the refrigerant is discharged upwards from the rotor core 2, the vertical direction can be directly in contact with the inclined part of the baffle 12, so that the separation of oil and the refrigerant is fully performed.

Embodiment four:

referring to fig. 3, the baffle 12 has a curved structure and covers the upper side of the first through hole 11, and the baffle 12 with a curved structure has the function of changing the flow direction, thereby being beneficial to the rotation of the rotor core in the compressor, reducing wind resistance to a greater extent, improving the power of the compressor and improving the energy efficiency.

In one example, the first through hole 11 is a quadrilateral hole, the first through hole 11 includes a first side and a second side in opposite relation, the baffle 12 extends from the first side of the first through hole 11 to contact with the second side, the baffle 12 with a curved surface structure is streamline and accords with the rotation direction of the rotor core, so that wind resistance can be reduced to a greater extent, the power of the compressor is improved, and the energy efficiency is improved.

Fifth embodiment:

referring to fig. 4, the baffle 12 is of an upwardly arched semi-cone structure, and is formed with a first opening 13 perpendicular to the oil 1, which is advantageous for forming a flow field for a refrigerant to rotate at a high speed in an upper space of a compressor housing, thereby more sufficiently separating the refrigerant from the oil and improving oil discharge of the compressor.

Example six:

in the conventional compressor structure, in order to reduce the oil content in the refrigerant discharged from the compressor, when designing the motor rotor assembly, it is considered to add an oil 1 at the upper end of the motor rotor, and the oil 1 is generally located at the upper end surface of the upper balance weight 3. However, the oil content 1 has a great influence on the process when the rotor assembly is produced, assembled and riveted. In order to prevent the rotor core 2 from being dislocated and ensure cylindricity during riveting of a normal rotor assembly, rivets positioned at the iron rotor core position and the balance weight 3 are generally riveted at the same time, and when oil 1 is added, the rivets positioned at the rotor core 2 position are blocked by the oil 1 and cannot be riveted at the same time; even if a notch is added to the rivet position corresponding to the oil component 1, the effective oil blocking area of the oil component 1 is greatly reduced, the strength is greatly reduced, and the deformation risk is high during high-speed rotation.

In view of the above problems, referring to fig. 5 and 6, there is provided a compressor in this example including a rotor core 2, a weight 3, and an oil 1 in any of the above embodiments, the oil 1 being located between the rotor core 2 and the weight 3; the rotor core 2 is provided with a refrigerant through hole 21, and the first through hole 11 and the refrigerant through hole 21 are in a relative position relation.

The oil content 1 is added between the upper end face of the rotor core 2 and the lower end face of the balance weight 3, so that the production, assembly and riveting process of the rotor assembly is not affected, and meanwhile, the separation of the refrigerant and the oil can be fully performed, and the oil discharge of the compressor is improved.

In one example, the oil 1 includes upper and lower surfaces disposed opposite to each other, and the baffle 12 protrudes from the upper surface; the upper surface of the oil 1 is in a flat shape at the position where it contacts the weight 3, and the lower surface of the oil 1 is in a flat shape at the position where it contacts the rotor core 2, thereby ensuring convenience in caulking assembly work.

The first through hole 11 and the refrigerant through hole 21 on the oil 1 are opposite, a baffle 12 extends towards the outside of the first through hole 11 at the edge of the first through hole 11, and fluid discharged from the refrigerant through hole 21 contacts with the baffle to separate the refrigerant from the oil, thereby improving the oil discharge of the compressor.

Wherein, balancing piece 3, oil content 1 and rotor core 2 pass through first rivet 4 locking connection, ensure the connection stability between balancing piece 3, oil content 1 and the rotor core 2, and then improve the job stabilization nature of compressor, and first rivet 4 passes balancing piece 3, oil content 1 and rotor core 2 in proper order, locks balancing piece 3, oil content 1 and rotor core 2 together.

Since the weight 3 does not cover the entire upper surface of the oil 1, the oil 1 and the rotor core 2 are locked and connected by the second rivet 5 at the axial position of only the oil 1 and the rotor core 2, so that the connection stability between the oil 1 and the rotor core 2 is ensured, and the operation stability of the compressor is further improved.

Referring to fig. 5, when the baffle plate 12 is in a perpendicular relationship with the oil 1 in the compressor, the baffle plate 12 is also perpendicular to the upper end surface of the rotor core 2, so that the compressor can be contacted with the refrigerant in a large area when rotating at a high speed, and the separation of the oil and the refrigerant is sufficiently performed.

Referring to fig. 7, when the baffle plate 12 is of an inclined flange structure in the compressor, the refrigerant is discharged upward from the refrigerant through hole 21 of the rotor core 2, and the vertical direction can directly contact the inclined portion of the baffle plate 12, thereby sufficiently separating oil from the refrigerant.

Referring to fig. 8, when the baffle 12 in the compressor is of a curved surface structure, when the refrigerant is discharged upward from the refrigerant through hole 21 of the rotor core 2, the baffle 12 formed by the curved surface structure changes the flow direction, so that the separation of oil and the refrigerant is fully performed, and the flow direction is opposite to the rotation direction of the rotor core 2, on one hand, the refrigerant contributes to the rotation of the rotor core 2 due to the acting force to the rotor when the flow direction changes, and on the other hand, the baffle 12 of the curved surface structure is streamline and accords with the rotation direction of the rotor core 2, so that the wind resistance can be reduced to the greatest extent, the power of the compressor is improved, and the energy efficiency is improved.

Referring to fig. 9, when the baffle plate 12 in the compressor has an upwardly arched half cone structure, the refrigerant is discharged upwardly from the refrigerant through hole 21 of the rotor core 2, flows out from the first opening 13 after passing through the baffle plate 12 having a half cone structure, and the direction of the first opening 13 is opposite to the direction of the rotor core 2, so that the refrigerant is biased to diverge to the periphery of the compressor shell, thereby helping the refrigerant to form a flow field rotating at a high speed in the upper space of the compressor shell, thereby more fully separating the refrigerant from the oil and improving the oil discharge of the compressor.

In summary, according to the oil for the compressor provided by the utility model, through the vertical design of the baffle plate on the oil, the contact of the fluid and the baffle plate with a larger area can be realized, and the separation of the oil and the refrigerant can be well realized; by designing the extending direction and the forming structure of the oil component upper baffle, the large-area contact between the fluid and the baffle can be realized, and the separation of oil and refrigerant can be well realized; the rotation of the rotor core is facilitated through the change of the fluid flow direction, the rotating wind resistance is reduced, and the improvement of the compressor energy efficiency is realized; or the refrigerant is favorable to forming a high-speed rotation flow in the upper space of the compressor shell after passing through the refrigerant through hole of the rotor core, thereby being favorable for separating the refrigerant from oil and improving the oil discharge; the oil is applied to the compressor, the production, assembly and riveting process of the rotor assembly is not affected, and meanwhile, the separation of the refrigerant and the oil can be fully carried out, so that the oil discharge of the compressor is improved.
