As shown in fig. 3, the mating surface 45 is in abutting engagement with the oil deflector 52 of the oil deflector cap.

The above may also be used in the technical field of air conditioner equipment, and according to another aspect of the present invention, there is provided an air conditioner, including a rotor assembly, where the rotor assembly is the rotor assembly in the above embodiments.

By adopting the rotor assembly, when the motor rotates, a low-pressure area can be formed above the rotor circulation hole due to the existence of the guide vane structure, so that the pressure of the inlet and the outlet of the rotor circulation hole is reduced, and the fluid can flow out of the circulation hole conveniently, so that the flow of the rotor circulation hole is improved; the fluid flows into the space between the oil blocking component and the oil blocking seat through the vertical through circulation channel of the rotor iron core, flows out through the side gap between the oil blocking component and the oil blocking seat, and the oil blocking seat and the oil blocking component provide centrifugal force for the fluid flowing through the gap between the oil blocking seat and the oil blocking seat, so that the oil-gas separation capacity is improved, and the oil carrying capacity of the compressor exhaust is reduced.

The flow ratio of each flow channel of the motor is shown in the following table, wherein a positive value indicates that the statistical flow is upward, and a negative value indicates that the statistical flow is downward. After adopting this application structure, the rotor flow hole upward flow increases by a wide margin, and the sum of stator side cut and solenoid clearance backward flow increases by a wide margin, and this kind of flow mode more is favorable to reducing the compressor and exhausts oil mass, explains to adopt this patent the structure more is favorable to reducing the compressor and tells oily rate.

Different boss scheme	Scheme 1	Scheme 2	Scheme 3	Scheme 4
					Rotor flow channel flow ratio	127.50％	139.01％	109.62％	196.99％
Stator flow channel flow ratio	-27.5％	-39.01％	-9.62％	-96.99％

Wherein, in table 1, in order to verify the effect of this application, designed four kinds of fender oil seat schemes altogether, the scheme details are as follows:

scheme 1: the upper surface of the oil baffle seat is provided with 3 uniformly distributed cylindrical bosses;

scheme 2: the upper surface of the oil baffle seat is provided with 6 uniformly distributed cylindrical bosses;

scheme 3: the upper surface of the oil baffle seat is provided with 3 uniformly distributed cylindrical bosses and 3 uniformly distributed guide vane structures opposite to the rotation direction of the compressor;

scheme 4: the oil baffle seat upper surface has 3 cylinder bosss of equipartition to reach 3 stator structures the same with compressor direction of rotation of equipartition.

Table 2 shows the test results of the oil baffle seat using three cylindrical bosses and the oil baffle seat embodiment of the present application, with the data of the prototype of the oil baffle seat using three cylindrical bosses as the reference, the data represents the fluctuation range of the relative reference value. From table 2, the capacity of each working condition point is improved, the power consumption is reduced, the comprehensive COP is improved by at least 0.79% and at most 3.42%, the oil spitting rate is generally reduced by more than 50%, and the scheme effect is obvious.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In addition to the foregoing, it should be noted that reference throughout this specification to "one embodiment," "another embodiment," "an embodiment," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment described generally throughout this application.
