(4) A rectangular raised limiting structure is arranged below and above the tail end of the oil baffle connecting part in the steps (1), (2) and (3).

As shown in fig. 4-1 and 4-2, which are part diagrams of the oil baffle of the present invention. The oil baffle is divided into a connecting part and an oil baffle part. The connecting part is in a slender rod shape, and a hinge groove is arranged on the lower side of the connecting part and can be mutually hinged and matched with the hinge head part in the hollow area of the upper flange. In addition, the upper end surface and the lower end surface of the connecting part are respectively provided with an upper convex limiting structure and a lower convex limiting structure, and the cross section of the convex part is rectangular and has the same width with the connecting part.

The utility model discloses still can restrict the motion range that keeps off oily structure through a plurality of limit structure's mating reaction, make its the biggest angle of upward movement can only move to the horizontal direction parallel, such structure can improve the area that blocks oil gas, prevents to make progress the perk and lead to hindering the reduction of oily efficiency, and then further improves the oil-gas separation rate.

When the compressor is started at low temperature and is in rest, the refrigerant oil in the oil pool moves from bottom to top and flows out from the waist-shaped hole of the upper flange while pressure difference is formed. At the moment, the frozen oil can impact the lower surface of the oil baffle sheet, so that the oil baffle ring enters a working state and rotates upwards until the lower limit part of the oil baffle ring connecting part is contacted with the horizontal plane of the hollow area, and then the oil baffle ring stops rotating and keeps in a horizontal state. In this state, the frozen oil is blocked by the oil blocking sheet and then flows back to the pump body and the oil pool along the inner wall of the frozen oil.

In some embodiments, θ satisfies: theta is less than or equal to 50 degrees; when the oil baffle structure 2 rotates to the position where the upper limit structure 214 abuts against the third limit structure 17, the oil baffle structure 2 is in the maximum inclination state, at this time, a projection area of the plane area 221 in an axial plane is S1, a projection area of the first flow through hole 13 in the axial plane is S2, and S1 > S2 is satisfied. The maximum inclination angle of the oil baffle can be effectively limited by the angle theta of less than or equal to 50 degrees, so that the oil baffle cannot buffer the frozen oil flowing back from the upper cavity due to the overlarge inclination angle; because of the inclined state, the horizontal projection area of the plane area of the oil baffle is smaller than the area of the plane area of the oil baffle in the horizontal state. The horizontal projection area of the plane area under the maximum inclined state of the oil baffle sheet is limited to be larger than the horizontal projection area of the waist-shaped hole of the upper flange, and the horizontal projection area of the waist-shaped hole of the upper flange is limited to ensure that the oil baffle sheet can completely cover the waist-shaped hole of the upper flange at any inclined angle, so that a large amount of refrigerating oil pumped out of the waist-shaped hole is effectively blocked.

(5) If the maximum included angle between the inclined oil blocking sheet and the horizontal direction is theta, the following requirements are met: theta is less than or equal to 50 degrees.

(6) The oil deflector as described in (1) (2) (3) (4) (5) is composed of a flat area and a curved area. If the horizontal projection area of the plane region under the maximum inclined state of the oil blocking sheet is S1, the horizontal projection area of the waist-shaped hole of the upper flange is S2, and the requirements are met: s1 > S2.

Keep off the oil piece and install in last flange fretwork area through articulated cooperation, in the compressor operation process, when the freezing oil mass that dashes out in the waist type hole of follow last flange is less, it is in quiescent condition to keep off the oil piece, its outside oil blocking part compares in the coupling part weight bigger, simultaneously because keep off between oil piece and the last flange through articulated cooperation, can rotate around articulated department between the two, under the effect of gravity, it can be to keeping off oil part one side below slope to keep off the oil piece, be favorable to the compressor epicoele freezing oil to flow back to the compressor pump body and oil bath in, strengthen the lubrication. After the upper limit part is inclined to a certain angle, the upper limit part can not be inclined continuously due to the contact with the inner wall of the hollow area, and the phenomenon that the oil blocking piece cannot buffer the returned refrigerating oil after being excessively inclined can also be avoided. Because the maximum inclination angle of the oil baffle piece is determined by the position and the size of the upper limit part at the connecting part, in order to ensure the oil return effect, the maximum inclination angle theta of the oil baffle ring needs to be ensured when the upper limit part is designed: theta is less than or equal to 50 degrees.
