Description

A kind of reciprocating compressor
Technical field
This utility model relates to a kind of reciprocating compressor.
Background technology
At present, the reciprocating compressor that domestic refrigeration industry uses, the existing rotary motion of connecting rod on compressor also has past On the one hand multiple motion, the i.e. major part of connecting rod make circumference rotary motion with crankpin, and on the other hand the microcephaly of connecting rod is together with piston Doing linear reciprocating motion, the power that the working method of connecting rod causes connecting rod to act on piston is an oscillatory forces being continually changing, Cause piston to have bigger lateral pressure effect to cylinder, cause piston that cylinder is produced bigger slamming, increase pendulum Dynamic amplitude, result adds the friction and wear of compressor, causes the sealing property of compressor to be deteriorated, and compression efficiency reduces, again Due to material cause so that cylinder and cylinder body motor rack can only use split to design mostly, compressor is caused to produce relatively further Big noise and vibration, and cause the increase of compressor power consumption, the lost of life.If amplitude of fluctuation to be reduced, then must the company of lengthening Pole length, it necessarily causes overall dimensions and weight to strengthen, and when household electrical appliance use reciprocating compressor, its parts Weight is required for considering, the cylinder of the reciprocating compressor that the reciprocating compressor on conventional domestic electrical equipment, such as refrigerator use Body motor rack uses cast iron materials mostly, and cylinder frame accounts for the significant portion of compressor gross weight, in order to reduce connecting rod swing amplitude, Reduce noise and vibration that compressor produces, and the weight of reduction compressor, solve mesh in the urgent need to a kind of new attachment structure Connecting rod, cylinder and the attachment structure of cylinder body motor rack on front reciprocating compressor.
Utility model content
The technical problems to be solved in the utility model is to provide the reciprocating of a kind of simple in construction, efficiency height and energy-saving safety Compressor.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of reciprocating compressor, including motor driver, the first pressure compressor and the second compressor, described motor drives Be provided with motor on dynamic device, described motor be provided above fixed mount, the lower end of described motor is provided with drive shaft, described Being provided with fixing bearing in drive shaft, the lower end of described drive shaft connects drive case, and the inside of described drive case is arranged Having bent axle, described bent axle is provided with piston rod, be provided with change between described piston rod, the end of described piston rod is provided with Piston, described first compressor is positioned at the lower left of drive case, described first compressor be internally provided with cylinder, described gas The two ends up and down of cylinder are provided with air inlet, and the front end of described cylinder is provided with gas outlet, and described second compressor is positioned at driving box The upper right side of body.
As preferably, described fixed mount covers motor fixing motor, desirably prevents motor and shakes in the running, produces Raw bigger noise.
As preferably, described drive shaft is connected with bent axle, is conducive to driving crank rotation.
As preferably, the avris of described drive case is provided with bearing, beneficially crank rotation.
As preferably, described bent axle is that S type is arranged, and is conducive to controlling the first compressor and the motion of the second compressor.
As preferably, described piston rod with crank for being flexibly connected.
As preferably, in described air inlet and gas outlet, all it is provided with plug, beneficially air inlet and giving vent to anger.
As preferably, described second compressor 3 is consistent with the shape of the first compressor 2.
The beneficial effects of the utility model are: owing to being provided with motor, and drive case can be driven to run, due to driving box Internal bent axle is set, piston rod movement can be driven by bent axle, owing to piston rod moves under the driving of bent axle, it is possible to make Piston moves forward and backward, owing to being provided with cylinder in the first compressor and the second compressor, it is possible under the motion of piston, gas enters Row compression.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of reciprocating compressor of this utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of reciprocating compressor, press compressor 2 and the second compression including motor driver 1, first Device 3, described motor driver 1 is provided with motor 4, described motor 4 be provided above fixed mount 5, described motor 4 times End is provided with drive shaft 6, and described drive shaft 6 is provided with fixing bearing 7, and the lower end of described drive shaft 6 connects drive case 8, described drive case 8 be internally provided with bent axle 9, described bent axle 9 is provided with piston rod 10, sets between described piston rod 10 Being equipped with change 11, the end of described piston rod 10 is provided with piston 12, and described first compressor 2 is positioned at the lower-left of drive case 8 Side, described first compressor 2 be internally provided with cylinder 13, the two ends up and down of described cylinder 13 are provided with air inlet 14, described The front end of cylinder 13 is provided with gas outlet 15, and described second compressor 3 is positioned at the upper right side of drive case 8.
Described fixed mount 5 covers motor 4 fixing motor 4, desirably prevents motor 4 and shakes in the running, produces bigger Noise.
Described drive shaft 6 is connected with bent axle 9, is conducive to driving bent axle 9 to rotate.
The avris of described drive case 8 is provided with bearing, and beneficially bent axle 9 rotates.
Described bent axle 9 is arranged for S type, is conducive to controlling the first compressor 2 and the second compressor 3 moves.
Described piston rod 10 with crank 9 for being flexibly connected.
