Description
Technical field
The utility model relates to a kind of refrigerator technical field of refrigeration compressors, is a kind of two revolution refrigerator refrigeration compressors that provide in order to solve problems such as the ubiquitous complex structure of current refrigerator refrigeration compressor, vibration are big, noise reaches poor reliability greatly.
Background technique
At present the domestic and international refrigerator refrigeration compressor overwhelming majority of producing has all adopted the structure of air-breathing, drain tap and connecting rod (or eccentric slide plate), thus caused the compressor arrangement complexity, vibration is big, noise is big, poor reliability and working life are short etc. defective.
Summary of the invention
Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of simple in structure, compact, vibration is little, noise is low, efficient is high and two revolution refrigerator refrigeration compressors of long service life.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this pair revolution refrigerator refrigeration compressor, the pump case that comprises a sealing, pump case is provided with tenminal block and is electrically connected with external power, it is characterized in that being provided with in the described pump case support and one and the motor that is fixed together of this support, one rotary cylinder-block that rotates synchronously with motor rotor is installed on the support, be covered with one on the cylinder body and fix the cylinder body that connects with support, be provided with seal ring between cylinder body and the support, cylinder is provided with suction tude and outlet pipe on one's body; Described cylinder body internal fixation has a fixing pin, and the relative rotary cylinder-block shaft axis of this fixing pin is eccentric to be provided with, one be installed in that rotary-piston rotary cylinder-block cylinder chamber in is rotatably assorted with this fixing pin and with rotary cylinder-block can be around this fixing pin rotation.
Described support can be inserted by three extension springs and hang in the pump case of sealing.
The center hole and the rotor close-fitting of motor rotor passed in the bottom of described rotary cylinder-block, with the synchronous rotation of realization with motor rotor.
Compared with prior art, advantage of the present utility model is: the utility model guarantees by an eccentric fixing pin of installing that rotary cylinder-block whenever circles makes rotary-piston finish the thermal procession of twice air-breathing, compression and exhaust, the air displacement of this compressor is doubled, therefore compare with existing refrigerator refrigeration compressor, under the cylinder diameter situation identical with rotating speed, the fixing pin throw of eccentric of this machine can reduce half, therefore the utlity model has advantage simple in structure, compact, that part is few, vibration is little, noise is low and efficient is high; Simultaneously, that the utility model compressor does not have is air-breathing, drain tap and connecting rod, so there is not quick-wear part in this machine, thereby reliability height, long service life.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the two revolution of the utility model refrigerator refrigeration compressor mainly is made of pump case 1, motor 4, support 7, cylinder body 6, rotary cylinder-block 5 and rotary-piston 3 etc., wherein motor 4 is fixed in support 7, rotary cylinder-block 5 is contained on the support 7, the bottom of this rotary cylinder-block 5 is bullet shaped, its head, can rotate with rotor with the rotor close-fitting by the center hole of motor rotor 12.The top of rotary cylinder-block 5 is cylindrical, laterally is provided with a cylinder chamber, is used for installing rotary-piston 3.Cylinder body 6 covers on the top of rotary cylinder-block 5, and tightens together with screw and support 7, and is provided with rubber o-ring 10 on both mating faces, to guarantee sealing between the two.Cylinder body 6 is provided with suction port 9 and outlet pipe 8.Cooperates and constitute accurate rotation between rotary cylinder-block 5 and cylinder body 6 and the support 7, directly axial clearance stops this compressor outlet pressurized gas to flow backwards to the import low-pressure cavity.Rotary-piston 3 is contained in the cylinder chamber of rotary cylinder-block 5, and is rotatably assorted with a fixing pin 2 that is fixed on cylinder body inside with rotary cylinder-block 5 shaft axis off-centre, and rotary-piston 3 rotates around this fixing pin 2 under the drive of rotary cylinder-block 5.
Assemble the back by three extension springs, 11 slotting hanging in the pump case 1 of sealing by the compressor that above-mentioned motor 4, support 7, cylinder body 6, rotary cylinder-block 5, fixing pin 2 and rotary-piston 3 etc. constitute, refrigerator is by compressor inlet, outlet pipe turnover, and power supply is electrically connected with external power by the tenminal block on the pump case.The cylinder chamber that compressor is surrounded by cylinder body 6, rotary cylinder-block 5 and rotary-piston 3, do rotation motion around the fixing pin 2 that off-centre is installed together by motor rotor 12 driven rotary cylinder bodies 5 and rotary-piston 3, and rotary-piston 3 is when fixing pin 2 rotates, and it is reciprocating in the cylinder of rotary cylinder-block 5 to follow fixing pin 2, thereby realize air-breathing, the compression of compressor and the thermal procession of exhaust, and rotary cylinder-block whenever circles and makes rotary-piston finish the thermal procession of twice air-breathing, compression and exhaust, and the air displacement of this compressor is doubled.Compare with existing refrigerator refrigeration compressor, under the cylinder diameter situation identical with rotating speed, the fixing pin throw of eccentric of this machine can reduce half.
