Abstract

The refrigerant path device for closed rotary compressor features that the refrigerant path for the refrigerant gas exhausted by the compression structure to flow through is formed on the side wall of the closed container in the closed rotary compressor. The refrigerant path with arced cross section is formed along the length direction of the closed container, and has starting point over the mechanical mechanism below the closed container and length range corresponding to that of stator inserted inside the motor. Owing to the formation of the refrigerant path on the closed container, the motor has its stator no need of cutting and thus high efficiency, and this also raises the performance of the closed rotary compressor.

Valve (valve) assembly (15) is equipped with in the outlet port of going up the exhaust port (10a) that forms at above-mentioned upper bearing (10), and the baffler (16) that is used for reducing exhaust noise is housed above the valve member (15).
In addition, a side of above-mentioned cylinder (9) is equipped with coupled logical liquid storage tank (accumulator) (17), and liquid storage tank (17) can prevent that liquid refrigeration agent from flowing into cylinder (9).Discharge tube (18) is equipped with at the top of above-mentioned seal container (1), and the higher pressure refrigerant gas that is compressed after structural portion (12) is compressed can be by this discharge tube (18) row to the outside.
If connected power supply having on the existing closed rotary compressor of said structure, the rotor (2) of motor (4) will rotate so, and the running shaft (5) that meanwhile is installed on the above-mentioned rotor (2) also can rotate thereupon.
Rotation along with above-mentioned running shaft (5), eccentric part (6) that forms in running shaft (5) lower end and the rotary-piston (7) that is connected on the eccentric part (6) also can rotate, and so just the refrigerant gas of low-temp low-pressure that can the compression volume (8) that be inhaled into cylinder (9) is inner is compressed into the refrigerant gas of High Temperature High Pressure.
Can pass through valve member (15) through refrigerant compressed gas and discharge, be discharged to the inside of seal container (1) then via the through hole (16a) of baffler (16).The refrigerant gas of the High Temperature High Pressure of these discharges can flow through slit and the both sides cutting portion (3a) of stator (3) and the passage between the seal container between rotor (2) and the stator (3), is discharged to the outside by discharge tube (18) at last.
But in aforesaid existing closed rotary compressor, in order to make the inside that to flow through seal container from the refrigerant gas of compression structure part discharge smoothly, need the method by cutting (cutting) form smear metal portion in the both sides of the stator of motor, and there is the problem of the efficient reduction that makes motor itself in this structure.
Summary of the invention
In order to overcome the above-mentioned shortcoming that prior art exists, the invention provides a kind of coolant channel device of closed rotary compressor, so that the refrigerant gas of discharging from compression structure part can flow through smoothly, and do not damage the efficient of motor, and promote the performance of closed rotary compressor self.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of coolant channel device of closed rotary compressor is characterized in that, has formed on the sidewall of the seal container of closed rotary compressor to make the coolant channel that flows through from the refrigerant gas of compression structure part discharge.
The coolant channel device of aforesaid closed rotary compressor, wherein the cross section of the coolant channel of seal container is arc surface, it forms along the length direction of seal container, its starting point is above the part that machinery is housed of seal container bottom, and length range is equivalent to be inserted in the length range of the stator of motor interior.
The coolant channel device of aforesaid closed rotary compressor, wherein the coolant channel of seal container is that method with drawing makes board-like material produce distortion and forms.
