Description
Technical field
The present invention relates to rotary compressor, particularly relate to the cylinder of rotary compressor.
Background technique
The rotary compressor that is applicable to air conditioner etc. usually with live axle that electric structure portion combines on eccentric rotary-piston in conjunction with compression structure part, rotary-piston is rotated motion in the compression volume of circular cylinder, thus suction, compression and discharging refrigerant.
The structure of existing rotary compressor as depicted in figs. 1 and 2, electric structure portion comprises: stator 2, rotor 3 and live axle 4.Stator 2 and rotor 3 are provided with the inside of machine at shell 1, and the center of rotor 3 is pressed into and is installed on the live axle 4, and the bottom of live axle 4 is provided with the compression structure part of suction, compression refrigeration gas.Compression structure part comprises: the circular cylinder 5 that is fixedly installed on casing week 1 inner face; The upper and lower bi-side while live axle 4 that is close to cylinder 5 connects wherein and supported upper bearing (metal) 6A and lower bearing 6B; Be arranged on the eccentric part 4a of live axle 4, at the rotary-piston 7 that off-centre is rotated in cylinder 5 under the effect of live axle 4; Be formed at the baffle plate groove 12 on the cylinder wall; Be arranged in the baffle plate groove 12, one end is crimped on the outer circumferential face of rotary-piston 7, the other end contacts with baffle plate spring (not shown), and is rotated the baffle plate (not shown) of doing straight line motion when moving and cylinder 5 being divided into suction chamber and compression chamber at rotary-piston 7; Be formed at the suction port 5a on the cylinder wall; Be formed on the cylinder wall, connect the suction passage 5b of suction port 5a, and be arranged on a side of casing 1 and be connected gas-liquid separator 10 on the suction port 5a of cylinder 5.Gas-liquid separator 10 possesses certain inside space, and its upper end connects the guard shield 11 of refrigerant pipe; Connect the Lower Half of above-mentioned guard shield 11, profound the insertion is fixed with air pipe 13.
The working procedure of above-mentioned rotary compressor is as follows:
Give stator 2 power supplies, make the inner rotation of rotor 3 at stator 2, meanwhile live axle 4 rotates and rotary-piston 7 off-centre in cylinder 5 is rotated, off-centre rotation along with rotary-piston 7, refrigeration agent is inhaled into the suction chamber of cylinder 5, and continues to be compressed to certain pressure, when the pressure in the compression chamber of cylinder 5 surpasses critical pressure, the drain tap 8 that is installed on the relief opening 6a of upper bearing (metal) 6A is opened, and pressurized gas drains in the casing 1 from compression chamber through relief opening 6a.The gas of discharging enters into the top of rotary compressor by the slit between the slit between casing 1 and the stator 2 or stator 2 and the rotor 3, passes through gas outlet pipe DP then and is discharged to the circulating frozen system.
But the suction port 5a of the cylinder of existing rotary compressor is illustrated in figure 2 as circle, because the position of compression beginning so effectively the volume of compression chamber is less, makes the compression efficiency of compressor lower at the end away from baffle plate groove 12 of circular suction port 5a.
Summary of the invention
In order to address the above problem, to the object of the present invention is to provide a kind ofly to have bigger effective compression chamber, thereby can improve the cylinder of rotary compressor of the compression efficiency of compressor.
In order to achieve the above object, technological scheme of the present invention is achieved in that
A kind of cylinder of rotary compressor, described cylinder comprises: the cylinder wall of annular; The rotary-piston of eccentric rotation in cylinder wall; Be formed at the baffle plate groove on the cylinder wall; Being arranged in the baffle plate groove and being crimped on the outer circumferential face of rotary-piston, is the cylinder interior spatial division baffle plate of suction chamber and compression chamber when rotary-piston rotates; Be formed on the cylinder wall, the suction port of baffle plate groove one side and be formed at the suction passage that is communicated with suction port on the cylinder wall, described suction port is a long-round-shape.
The major axis of above-mentioned long-round-shape suction port is vertical with the end face of cylinder.
Be formed with the domatic chamfering in the joint of above-mentioned suction port and suction passage.
The cylinder of rotary compressor of the present invention, the cross-section area of long-round-shape suction port is identical with the cross-section area of the circular suction port of prior art, and the long-round-shape suction port is identical with the central position of the circular suction port of prior art.Like this, guaranteeing to have increased the effective volume of compression chamber under the identical situation of air inlet performance, therefore can improve the efficient of compressor greatly.

Embodiment
Be elaborated below in conjunction with the structure of accompanying drawing to the cylinder of rotary compressor of the present invention.
As shown in Figure 3 and Figure 4, the cylinder of rotary compressor of the present invention comprises: the cylinder wall 23 of annular; The rotary-piston (not shown) of eccentric rotation in cylinder wall; Be formed at the baffle plate groove 22 on the cylinder wall 23; Being arranged in the baffle plate groove 22 and being crimped on the outer circumferential face of rotary-piston, is the cylinder interior spatial division baffle plate (not shown) of suction chamber and compression chamber when rotary-piston rotates; Be formed on the cylinder wall 23, the suction port 25a of baffle plate groove 22 1 sides and be formed on the cylinder wall 23, be communicated with the suction passage 25b of suction port 25a.
In order to improve the effective volume of cylinder compression chamber, the shaped design of suction port 25a of the present invention becomes long-round-shape, and the major axis of long-round-shape suction port 25a is vertical with the end face of cylinder.The central position of suction port 25a is identical with the central position of the circular suction port 5a of the rotary compressor cylinder of prior art, and its sectional area is identical with the sectional area of the circular suction port 5a of prior art cylinder.In addition, in order to reduce flow resistance, be formed with domatic chamfering 25c in the joint of suction port 25a and suction passage 25b.
Working procedure to the cylinder of rotary compressor of the present invention describes below.
When compressor operating, rotary-piston is eccentric rotation in cylinder 25, off-centre rotation along with rotary-piston, refrigeration agent is through suction passage 25b and suck the suction chamber that 25a is inhaled into cylinder 25, and continue to be compressed to certain pressure, when the pressure in the compression chamber of cylinder 25 surpassed critical pressure, pressurized gas was discharged through relief opening.In cylinder of the present invention, because the position of compression beginning is at the end away from baffle plate groove 22 of long-round-shape suction port 25a, and the length of the minor axis of long-round-shape suction 25a sucks the diameter of 5a less than the circle of prior art cylinder, so the cylinder of rotary compressor of the present invention has bigger compression chamber, thereby can improve the compression efficiency of compressor greatly.
