The working principle of the compressor provided in this embodiment is:

The refrigerant from the air conditioner system first passes through the liquid separation assembly 1 for gas-liquid separation, and the gas at the separation place enters the upper chamber of the motor assembly 4 from the second pipeline 12 at the bottom of the cylinder 13, and then passes through the flow hole on the motor rotor, the stator The gap between the rotors, the enameled wire gap, and the trimming of the stator flow to the lower chamber of the motor assembly 4, and then enter the suction port (ie the second ventilation hole 36) of the cylinder 34 from the first ventilation hole 35 of the upper flange 31, and then Compressed under the action of the cylinder 34 and other parts of the pump body, when the pressure of the compressed refrigerant is higher than the back pressure of the exhaust valve on the lower flange 33, the exhaust valve is pushed open, and then the refrigerant enters into the cavity of the lower flange 33, and then discharge the compressor from the exhaust pipe 51 on the cavity of the lower flange 33 and enter the air conditioner system; while the separated liquid passes through the first connecting pipe 14 and the second connecting pipe 23 enters the cavity formed by the upper cylinder 21 and the lower cylinder 22, and then discharges or enters the evaporator of the air conditioner.

The compressor provided by this embodiment cancels the upper cover of the compressor, and the cylinder body 13 directly plays the role of the upper cover, and is welded to the upper part of the compressor by welding, so that the center of gravity of the compressor is closer to the center of the compressor, so that the running The time is more stable, thereby reducing the vibration of the compressor caused by the unbalanced force and the noise generated thereby; at the same time, because the liquid separator assembly 1 is placed on the top, the liquid separator bracket, liquid separator pressure plate, rubber pad, etc. are cancelled, It has the advantage of cost saving; moreover, the liquid separator bracket is canceled and the liquid separator is not directly connected to the suction pipe, the vibration generated inside the compressor is not easily transmitted directly to the liquid separator, which avoids the excessive vibration of the liquid separator question.

Not only that, the suction pipe (i.e. the second pipeline 12) of the compressor provided in this embodiment is arranged at the lower part of the cylinder body 13, and the intake air directly leads to the upper chamber of the motor assembly 4 to cool down the motor and improve the efficiency of the motor. Then enter the cylinder 34 through the first vent hole 35 of the upper flange 31 to be compressed, and then the compressed refrigerant is discharged to the cavity of the lower flange 33 through the lower flange 33, and then passes through the lower flange 33. The exhaust pipe 51 is discharged to the inside of the system for circulation; in addition, in the compressor provided by this embodiment, the pump body assembly 3 is always in the low-pressure chamber, which reduces the pressure difference between the inner wall of the compressor shell and the external atmospheric pressure, so that the design can be thinner The unique compressor housing plays a role in saving development costs.

That is to say, the compressor provided in this embodiment cancels the liquid separator support, and the suction pipe is not directly connected to the pump body assembly, so the vibration generated inside the compressor is not easily transmitted directly to the liquid separator, causing the vibration of the liquid separator to be biased. At the same time, it can also make the center of gravity of the compressor closer to the center of the compressor and the center of the compressor is lower, so that the operation of the compressor is more stable, thereby avoiding the vibration of the compressor due to the unstable center of gravity.
