In this embodiment, the low-pressure refrigerant flowing into the casing 110 through the suction port 112 is diffused by the guide member 180, through the seventh passage 126 of the stator 122, into the first muffler assembly 190, the lubricating oil 300, which has flowed out through the first passage 132 of the crankshaft 130 and through the second passage 134 of the first bearing 142, also flows into the first muffler assembly 190, the refrigerant and the lubricating oil 300 are merged and both flow into the compression chamber 160 through the fourth passage 152, and are compressed in the compression chamber 160, and enters second muffler assembly 170 through fifth passage 154, and flows into vane chamber 168 through sixth passage 156, the sliding surface of the vane 146 is lubricated, the refrigerant is discharged through the discharge port 114, and the path of the compressed refrigerant is increased, thereby reducing the possibility of overheating the refrigerant, reducing the loss of cooling energy, and reducing the possibility of discharging the lubricating oil 300.

As shown in fig. 1, the low pressure rotary compressor 100 includes a motor assembly 120, a compression assembly 140 driven by the motor assembly 120, and a lubricating oil 300 accommodated in a casing 110.

The motor assembly 120 includes a stator 122 fixed in the housing 110, a rotor 124 disposed in the stator 122, the rotor 124 being linked with a crankshaft 130, the crankshaft 130 being capable of driving the compression assembly 140 to operate, the air inlet 112 being disposed at a middle position of an end of the housing 110, and a flow guide assembly 180 being disposed at a position of the crankshaft 130 corresponding to the air inlet 112.

The compressing assembly 140 includes a first bearing 142 and a second bearing 166 fixed on the housing 110, and further includes a cylinder mechanism 144 connected between the first bearing 142 and the second bearing 166, the first bearing 142 and the second bearing 166 are slidably engaged with the crankshaft 130, the crankshaft 130 has an eccentric shaft for driving a movable member in the cylinder mechanism 144, a slider groove is disposed on a cylinder body of the cylinder mechanism 144, the slider 146 is slidably disposed in the slider groove and connected to the movable member, and an elastic member 162 is disposed between the slider 146 and the housing 110.

The first bearing 142 is provided with a first noise reduction assembly 190, the second bearing 166 is provided with a second noise reduction assembly 170, and the lubricating oil 300 located at the bottom of the housing 110 flows into the groove 136 on the crankshaft 130 through the first passage 132 on the crankshaft 130 and flows toward the first bearing 142.

Specifically, the lubricating oil 300 can flow into the interior of the first muffler through the groove 136 provided on the crankshaft 130 and the second passage 134 on the sliding surface of the first bearing 142.

Next, the low-pressure refrigerant operation of the casing 110 will be described. When the compression unit 140 operates, the low-pressure refrigerant flowing out of the suction port 112 collides with the guide unit 180 fixed to the crankshaft 130 and rotating at a high speed, and the gaseous refrigerant and the liquid refrigerant are guided by the guide unit 180 and spread to the outer circumference of the stator 122.

The diffused gas-liquid mixed refrigerant flows into the seventh passages 126 at the outer circumference of the stator 122, thereby reducing the possibility of overheating of the motor assembly 120, and the refrigerant flows into the space between the motor assembly 120 and the compression assembly 140 through the seventh passages 126, then enters the first noise reduction assembly 190, and enters the first noise reduction assembly 190 through the hole passage at the upper end of the first noise reduction assembly 190, at this time, the lubricating oil 300 flows into the first noise reduction assembly 190 through the first passage 132 and the fourth passage.

Each peripheral groove is not overheated by the motor and moves to the lower space of the motor. Then, the low-pressure muffler moves from the upper end hole of the muffler to the inside of the muffler. At this time, an appropriate amount of lubricating oil 300 flowing out of the oil supply hole is mixed with the low-pressure gas inside the muffler.

The mixture of the refrigerant and the lubricating oil 300 flows into the compression chamber 160 through the fourth passage 152 from the first muffler assembly 190, is compressed by the movable member in the compression chamber 160 to become a high-pressure refrigerant, and then flows into the second muffler assembly 170 through the fifth passage 154 of the second bearing 166.

The high pressure refrigerant then passes through the sixth passage 156 of the second bearing 166, into the vane chamber 168, through the eighth passage 164 of the first bearing 142, into the discharge port 114, and out of the compressor 100.

As shown in FIG. 2, a cross-sectional view of compressor 100, the bottom surface of compression assembly 140 in cross-section represents a perspective view of compression chamber 160 and vane chamber 168, second muffler assembly 170, etc. The second muffler assembly 170 is fixed and sealed to the second bearing 166 by 6 screws, and the compression chamber 160 of the cylinder mechanism 144 located therein is indicated by a dotted line. The suction port of the compression chamber 160 communicates with the fourth passage 152 of the first bearing 142, and the discharge port of the compression chamber 160 communicates with the fifth passage 154 of the second bearing 166.

The movable member connected to the vane 146 rotates along with the rotation axis of the eccentric shaft of the crankshaft 130, and further discharges high-pressure refrigerant into the second muffler assembly 170, the high-pressure refrigerant includes a proper amount of lubricating oil 300, when the refrigerant and the lubricating oil 300 pass through the vane chamber 168, the lubricating oil 300 can lubricate the vane 146, and the high-pressure refrigerant and the elastic member 162 can jointly promote the return of the vane 146.

As shown in fig. 1, since the compression chamber 160 contains the mixture of the refrigerant and the lubricating oil 300 and the mixture of the refrigerant and the lubricating oil 300 discharged from the second muffler assembly 170, the vane 146 can be lubricated in the compression chamber 160 and the vane chamber 168, and an oil separator is not required to be provided to supply oil to the vane 146.

The pressure inside the housing 110 is low, and when the compression assembly 140 operates, if the high-pressure refrigerant of the compression chamber 160 leaks into the low-pressure moving part, the inside of the moving part becomes medium-pressure or high-pressure. Similarly, since the pressure in the first channel 132 of the crankshaft 130 is low, the medium-pressure or high-pressure gas leaked from the compression chamber 160 into the movable member flows back to the first through hole in the central hole of the crankshaft 130, and therefore, the third channel 148 is provided on the first bearing 142 and/or the second bearing 166 to communicate the interior of the movable member with the oil sump and/or the first space in the housing 110, so as to achieve pressure equalization, so that the lubricating oil 300 can normally lubricate the movable member, the first bearing 142 and the second bearing 166, and also can normally lubricate the sliding vane 146. If the amount of refrigerant leaking is small, the third passage may communicate the interior of first muffler assembly 190 with compression chamber 160.

As shown in fig. 3, the deflector assembly 180 includes a rotating portion 182 formed by stamping a steel plate, the rotating portion 182 may have a cylindrical shape, 4 protruding blade portions 184 are provided on the rotating portion 182, and a fixing shaft is added to the center of the rotating portion 182. The fixed shaft is pressed into the end of the crankshaft 130.

The guide assembly 180 of the present invention serves to prevent the low-pressure refrigerant flowing in from the suction port 112 from being expanded due to the heating of the motor assembly 120, thereby increasing the cooling capacity, and the refrigerant containing the low-pressure gas and the liquid refrigerant are diffused by the guide assembly 180, thereby reducing the possibility that the liquid refrigerant is sucked into the compression chamber 160 and compressed in the compression chamber 160, thereby increasing the reliability of the compressor 100.
