Description

A kind of horizontal rotor-type compressor

Technical field

The utility model relates to a kind of horizontal rotor-type compressor that is used for refrigeration air-conditioner.

Background technique

As everyone knows, the volumetric efficiency of rolling rotor type compressor, adiabatic efficiency have good energy-saving effect apparently higher than Reciprocting piston compressor, therefore, nowadays, rolling rotor type compressor has obtained ripe application in the family expenses field of air conditioning, thereby its cost is descended greatly.Existing rolling rotor type compressor mostly is vertical structure, and its advantage is that the compressor oil yielding rate of this structure is fewer, and reliability is higher; Yet its maximum shortcoming is that compressor needs configuration space big, and is higher to the use occasion spatial requirement.For conserve space, can change rolling rotor type compressor into horizontal type structure, yet, the compressor of available technology adopting horizontal type structure, its oil yielding rate can obviously increase, thereby causes refrigeration system heat exchange deleterious, and compressor reliability reduces.Therefore, how to solve above-mentioned two large problems simultaneously, become the problem of Professional visitors's primary study.

The model utility content

In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide a kind of novel horizontal rotor-type compressor, so that refrigerator oil effectively, separate in compressed refrigerant reliably, reach the purpose that reduces oil pump capacity, and on the basis that does not change product form, reduce cost in the mode of producing in enormous quantities, obtain better product performance price ratio.

A kind of horizontal rotor-type compressor described in the utility model, it comprises the casing of being made up of front shell cover, housing and rear shell cover, the motor that is arranged on this casing inside, bent axle, oil sump and assembling all-in-one-piece front end housing, the cylinder that is provided with exhaust port and back cylinder cover

Be respectively equipped with a through hole on described front end housing, cylinder and the back cylinder cover, and described three through holes constitute first drain passageway;

The installed in front of described front end housing has a silencer cover, makes and forms a closed exhaust volume between this silencer cover and the described front end housing.

Above-mentioned horizontal rotor-type compressor comprises that also one is installed in closing cap described back cylinder cover rear side and that have a fuel sucking pipe, and an end of described fuel sucking pipe stretches in the described oil sump, and the other end is connected with described bent axle.

In above-mentioned horizontal rotor-type compressor, described front end housing is provided with a relief opening, and the position of this relief opening is corresponding with the position of described cylinder upper air-vent.

Owing to adopted above-mentioned technical solution, the utility model is by a kind of special working medium flow path of design, promptly the refrigerant of discharging from the front end housing relief opening directly is not discharged in the housing, but be disposed to the closed exhaust volume that front end housing constitutes in silencer cover earlier, be directed to the housing back space through first drain passageway again, flowing to front space at last discharges, thereby increased the buffer space before refrigerant is discharged, improved the separating effect of the refrigerator oil before the exhaust, make refrigerator oil effective, in compressed refrigerant, separate reliably, reached the purpose that reduces oil pump capacity; In addition, aspect ratio vertical compressor of the present utility model reduces half, thereby has effectively improved the compressor configuration space, can reduce cost by the mode of producing in enormous quantities on the basis that does not change product form, obtains better product performance price ratio.

Fig. 2 is the sectional view of cylinder under installment state in a kind of horizontal rotor-type compressor of the utility model.

Embodiment

Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated.

See also Fig. 1, Fig. 2, the utility model, be a kind of horizontal rotor-type compressor, comprise the casing 2 of the sealing that forms by front shell cover 1, housing 7 and rear shell cover 9 welding, the bent axle with eccentric part 3 that is arranged on casing 2 inside, motor 4, oil sump 14 and assembling all-in-one-piece front end housing 6, cylinder 8 and back cylinder cover 10.

Bent axle 3 is by front end housing 6 (front end housing 6 also plays main bearing simultaneously) and back cylinder cover 10 supportings (back cylinder cover 10 plays supplementary bearing simultaneously), its axis is to be provided with from the horizontal by a mode less than 10 ° angle, the eccentric part of bent axle 3 is positioned at cylinder 8 inside, and is set with rolling piston 11 on this eccentric part.

Cylinder 8 is provided with a guide groove (not shown), and this guide groove inside is equipped with blade 15, cylinder 8 tops are provided with the spring assembly 16 that rolling piston 11 is applied the elastic force effect, under the driving of motor 4, bent axle 3 rotations drive rolling piston 11 and make eccentric rotary in cylinders 8, blade 15 moves reciprocatingly in guide groove, and blade 15 tops are pressed in the outer round surface of rolling piston 11 all the time, to constitute compression chamber, and be the boundary with blade 15, exhaust port 81 and suction port 82 are set on cylinder 8, the compression chamber in the cylinder 8 is divided into exhaust side 810 and suction side 820.

Same position place on front end housing 6, cylinder 8 and the back cylinder cover 10 is provided with a through hole respectively, and these three through holes constitute first drain passageway 23.Front end housing 6 is provided with air valve device (not shown) and the relief opening (not shown) corresponding with exhaust port 81 positions of cylinder 8, the installed in front of front end housing 6 has a silencer cover 5, and guarantee the sealing of both junctions, formation one closed exhaust volume 24 between the silencer cover 5 that makes sealing and the front end housing 6.The rear side of back cylinder cover 10 is equipped with a closing cap 12 that has a fuel sucking pipe 13, and both combine closely, one end of fuel sucking pipe 13 stretches into oil sump 14, the other end is connected with bent axle 3, make under the pressure difference effect, can suck and promote the intermediate hole (be high and low pressure volume path) of refrigerator oil from the oil sump 14 that is arranged in casing 2 bottoms, supply with lubricated to each friction position refrigerator oil by fuel sucking pipe 13 to bent axle 3.

Working principle of the present utility model is as follows:

After motor 4 starts,, working medium is sucked cylinder 8 from external system through liquid-storage container 20, air intake passage 22 and sucking pipe 21, and in its compression chamber, compress earlier by the intakeport 19 on the housing 7; The refrigerant of Xing Chenging at first is disposed to closed exhaust volume 24 by the relief opening on the front end housing 6 after compression, cause in the space of back cylinder cover 10 rear sides through first drain passageway 23 again, because it is big that spatial volume becomes, the airspeed that makes is disperseed on all directions, is slowed down, help fluid drips in the refrigerant cohesion and whereabouts, thereby effectively reduce oil pump capacity, simultaneously, the refrigerator oil that falls into oil sump 14 is assigned to the position that each need lubricate by fuel sucking pipe 13; After the separation of the refrigerator oil in the refrigerant, remaining pressurized gas passes through the space (i.e. second drain passageway) beyond back cylinder cover 10, cylinder 8, front end housing 6 and the silencer cover 5 again, flow to the casing front cavity, through and cooling motor 4 after, discharge compressors in the outlet pipe 18 from the front shell cover 1.
