Description

Compressor{compressor}

The present invention relates to a flow path separation unit that separates a refrigerant gas flowing upward and oil flowing downward in a compressor.

In general, a compressor is a machine used for generating high pressure or transporting a high pressure fluid, and a compressor applied to a refrigeration cycle such as a refrigerator or air conditioner performs a role of compressing refrigerant gas and transmitting it to a condenser.

Among these compressors, the scroll compressor has a fixed scroll fixed in the inner space of the closed case, and the fixed scroll is engaged with the orbiting scroll to perform the orbiting motion, and a compression chamber that is continuously generated between the fixed wrap of the fixed scroll and the orbiting wrap of the orbiting scroll. Through this, the refrigerant gas is suctioned and gradually compressed and discharged continuously and repeatedly.

Recently, a compression unit consisting of a fixed scroll and a slewing scroll is located under the electric unit that transmits power to rotate the slewing scroll, and a lower compression type that directly receives refrigerant gas and compresses it and provides it to the upper space in the sealed case and discharges it. A high-pressure compressor of is provided, and related thereto, as provided in Patent Publication No. 10-2018-0083646 (Prior Document 1) and Patent Publication No. 10-2018-0115174 (Prior Document 2).

Meanwhile, the lower compression type high pressure compressor according to the above-described conventional techniques is provided with a flow path separation unit (a flow path separation unit in the case of Prior Document 1) for separating the flow of refrigerant gas and oil.

This flow path separation unit is provided between the electric part and the main frame in the inside of the sealed case, and it is compressed in the compression part and then rises, lubricating the refrigerant gas flowing to the upper discharge space in the sealed case and each sliding part, and then flowing down. It is made to prevent the oil provided to the lower oil space in the sealed case from meeting with each other.

That is, the oil is interfering with the discharge flow of the refrigerant gas through the additional provision of the flow path separation unit, thereby solving the problem of generating flow path resistance, while preventing the oil shortage phenomenon in the compressor by mixing the oil in the refrigerant gas and discharging it to the outside. I made it possible.

In addition, the flow path separation unit according to the prior art described above provides a sealing member (refer to Prior Document 2) between the gap with the outer partition wall of the motor insulator constituting the electric unit to prevent leakage of refrigerant gas or the inflow of oil through the gap. To be able to do it.

However, since the sealing member of the prior art described above is provided with a conventional O-ring, it is difficult to assemble.

That is, the sealing grooves are formed in concave portions respectively opposite to each other of the flow path separation unit and the motor insulator so that the sealing member can be seated in the correct position, but it is difficult to accurately form these sealing grooves and the positions of each other are accurately In case of disagreement, it is difficult to accurately mount the sealing member, which takes a long assembly time, and when the sealing member is dried, it cannot be found, and thus, bonding has to occur during manufacturing.

Moreover, the above-described sealing member may not only deviate from its original position when used, but also may be damaged.

Publication Patent No. 10-2018-0083646 Publication Patent No. 10-2018-0115174

The present invention was conceived to solve various problems according to the prior art described above, and an object of the present invention is to stably prevent leakage of oil or refrigerant gas through the gap between the oil separation unit and the motor insulator. It is to provide a compressor to which an oil separation unit according to a new shape is applied so that installation can be made easily.

The compressor of the present invention for achieving the above object comprises: a motor provided in a sealed case; A compression unit that compresses the refrigerant gas while being operated by the rotating shaft; A main frame supporting the compression unit and the rotating shaft; And a flow path separation unit for separating the flow of the refrigerant gas flowing into the space between the main frame and the electric unit through the refrigerant flow path and the oil flowing down along the inner wall side of the sealed case, wherein the flow path separation unit is fixed to the main frame while It is characterized in that it comprises a flow path guide having an outer circumferential wall, and an airtight member installed on the outer circumferential wall of the flow guide to close a gap between the flow guide and the transmission unit while being raised and lowered by the pressure of the refrigerant gas.

The airtight member may be installed to be elevating on the inner circumferential surface of the outer circumferential wall of the flow guide.

In addition, a seating groove may be formed that is opened upward along the circumference of the upper end of the inner circumferential surface of the outer circumferential wall forming the flow guide.

Along with this, the airtight member may be formed in a pipe shape that is mounted on the bottom surface of the seating groove, and the outer circumferential surface thereof is in contact with the inner peripheral surface of the seating groove while receiving support.

In addition, a bent end that is bent toward the inside of the flow guide may be further formed at an upper end of the airtight member.

The thickness of the airtight member may be formed to be less than 1/2 of the thickness of the bent end.

The height of the airtight member may be formed longer than the protruding length of the bent end.

In addition, the electric unit is configured to include a motor insulator for winding and insulation of the coil, and a support jaw is formed around a bottom surface of the motor insulator, and the airtight member is formed from a flow path guide when the bent end contacts the support jaw. It can be formed to have a height that does not deviate.

In addition, the support jaw of the motor insulator may be formed to block at least a portion of the upper side of the seating groove formed in the flow guide.

Further, the airtight member may be positioned between the bottom surface of the seating groove and the support jaw.

In addition, the outer circumferential surface of the airtight member may be in close contact with the inner circumferential surface of the seating groove so that the upper surface is in close contact with the bottom surface of the support jaw when the refrigerant gas moves upward.

In addition, the airtight member may be formed of a Teflon material.

As described above, the compressor of the present invention has the effect of improving the assembling property as the airtight member constituting the flow path separation unit is formed in a pipe shape having rigidity rather than forming an O-ring. That is, since the pipe-type airtight member is not fitted to the flow guide but is coupled by a simple mounting method, the entire coupling operation can be performed easily and quickly.

In addition, since the airtight member constituting the compressor of the present invention is formed in a pipe shape having rigidity rather than an O-ring made of rubber, it is possible to prevent the occurrence of assembly defects such as warping during assembly and operation failures such as warping during operation. It has an effect that has become possible.

In addition, since the flow path separation unit constituting the compressor of the present invention does not form a sealing groove for installation of the O-ring in the flow guide, it is only necessary to form a seating groove having a stepped structure, so that injection molding is possible and thus has the effect of advantageous in mass production.

In addition, the flow path separation unit constituting the compressor of the present invention has a structure that closes the gap between the outer circumferential wall of the flow guide and the outer partition of the motor insulator while the airtight member rises due to the pressure of the refrigerant gas. By opening the gap, the pressure difference for all parts of the compressor can be quickly resolved.

At this time, the lower surface of the circumferential side of the body end 510 is formed to protrude downward and the upper surface of the fixed scroll 310 is fixedly installed.

Next, the flow path separation unit 600 is provided to separate the refrigerant gas and oil flowing in the sealed case 100 from each other.

As shown in the accompanying Figures 4 to 6, the flow path separation unit 600 includes a flow path guide 610 and a flow path guide 610 provided between the main frame 100 and the electric power unit 200. It includes an airtight member 620 that blocks the inner and outer spaces of the flow guide 610 while being guided and moving up and down.

Here, the flow path guide 610 is fixedly installed on the main frame 100 and provided to separate the flow portion of the refrigerant gas from the flow portion of the oil.

In particular, the flow path guide 610 is formed in a ring shape with an open inside and is mounted and fixed on the upper surface of the body end 510 forming the main frame 500. In addition, an outer circumferential wall 611 is formed around the outer circumference of the flow guide 610 and an inner circumferential wall 612 is formed around the inner circumference of the flow guide 610.

On the other hand, a refrigerant through which the refrigerant gas discharged into the discharge cover 350 passes at a portion between the fixed scroll 310 and the body end 510 of the main frame 500 and the respective circumferential walls 611 and 612 of the flow guide 610 Holes 314, 514, 614 (refer to FIGS. 1 and 4) are formed to be aligned with each other, and the transmission part 200 is disposed between the outer circumferential surface of the motor insulator 230 and the body end 510 forming the main frame 500. Oil grooves 235, 515, and 615 (refer to FIGS. 1, 2, and 6) are formed on the outer circumferential surface and the outer circumferential surface of the flow path guide 610 to allow oil to flow down.

In addition, the airtight member 620 is a portion provided to close a gap between the flow path guide 610 and the transmission unit 200 while being raised and lowered by the pressure of the refrigerant gas.

Such an airtight member 620 is installed on the outer circumferential wall 611 of the flow guide 610, is made of a Teflon (TPET) material having rigidity and is formed in a pipe shape having an outer circumferential surface and an inner circumferential surface. That is, in the embodiment of the present invention, by forming the airtight member 620 with a pipe made of a Teflon material, it is possible to prevent assembly defects such as distortion during installation, while allowing easy assembly work.

In particular, a seating groove 616 opened upward along an upper end circumference of the outer circumferential wall 611 is formed on the inner circumferential surface of the outer circumferential wall 611 constituting the flow guide 610, and the airtight member 620 ) Suggests that the outer peripheral surface of the seating groove 616 is mounted in the seating groove 616 and raised and lowered while being supported while being in contact with the inner peripheral surface of the seating groove 616.

At this time, the support jaw 234 of the motor insulator 230 is formed to block at least a portion of the upper side of the seating groove 616 formed in the flow path guide 610, and the airtight member 620 is the seating groove ( In addition to being located between the bottom surface of the inner 616 and the support jaw 234, the outer circumferential surface is in close contact with the inner circumferential surface of the mounting groove 616 so that the upper surface is in close contact with the bottom surface of the support jaw 234 when the refrigerant gas moves upward.

In addition, a bent end 621 bent toward the inside of the flow guide 610 is further formed at the upper end of the airtight member 620. The bent end 621 is formed to expand so that the airtight member 620 can rise due to the pressure of the refrigerant gas introduced into the flow guide 610, and when the airtight member 620 is moved upward, the corresponding bent end 621 ) Is made so that the upper surface is in close contact with the bottom surface of the support jaw (234).

At this time, the airtight member 620 is formed to have a height such that it does not deviate from the flow path guide 610 when the bent end 621 abuts the support jaw 234, the outer diameter of the airtight member 620 It is formed smaller than the inner diameter of the seating groove 616.

In particular, since the thickness (T1) of the airtight member 620 is formed to be less than 1/2 of the thickness (T2) of the bent end 621, the operation of the airtight member 620 by supply of refrigerant gas At the same time, expansion and deformation of the airtight member 620 can be made together.

In addition, the length H formed by the height of the airtight member 620 is formed to be longer than the protruding length L of the bent end 621, thereby preventing erroneous assembly and enabling a stable operation.

In the following, the operation of the compressor according to the embodiment of the present invention described above will be described in more detail with reference to FIGS. 7 to 9.

First, when the operation of the compressor is controlled, power is supplied to the electric unit 200 so that the rotor 220 of the electric unit 200 rotates.

In addition, when the rotor 220 is rotated, the rotation shaft 400 installed to pass through the center of the rotor 220 is also rotated together with the rotor 220.

In addition, when the rotation shaft 400 is rotated, the compression unit 300 is operated to compress the refrigerant gas in the compression chamber. That is, when the rotation shaft 400 is rotated, the orbiting scroll 320 eccentrically coupled to the lower end of the rotation shaft 400 rotates from the axial center of the rotation shaft 400, and in the process, the orbiting scroll 320 ), one outer surface of the involute-type orbiting wrap 321 is gradually moved along the inner surface of the involute-type fixed wrap 311 formed on the fixed scroll 310 to create a continuous compression chamber while being sucked into the corresponding compression chamber. The refrigerant gas is gradually compressed.

In addition, when the refrigerant gas is compressed in the compression chamber between the fixed wrap 311 and the orbiting wrap 321, the refrigerant gas flows into the refrigerant inlet pipe 330 connected to the fixed scroll 310. At this time, the refrigerant gas is forcibly sucked into the compression chamber from the accumulator 340 as a differential pressure due to the pressure formed inside the fixed scroll 310, and the fixed wrap 311 is continuously rotated by the orbiting scroll 320. It is gradually compressed while flowing along the compression chamber continuously generated between the and the orbiting wrap 321.

In addition, the compressed refrigerant gas is discharged to the bottom of the compression unit 300 through the discharge port 312 of the fixed scroll 310. At this time, a discharge cover 350 is provided at the bottom of the compression unit 300, whereby the refrigerant gas discharged through the discharge port 312 is stored in the discharge cover 350.

Then, the refrigerant gas discharged into the discharge cover 350 sequentially passes through the peripheral portion of the fixed scroll 310 and each of the refrigerant holes 314, 514, 614 of the main frame 500 and the flow guide 610, and then the flow guide. It is provided as a space within 610. This is as shown in the accompanying Figures 7 and 8.

In addition, when the refrigerant gas is provided to the space within the flow path guide 610, the airtight member 620 placed on the seating groove 616 of the flow guide 610 is As the pressure gradually rises, the upper surface of the bent end 621 is in close contact with the lower surface of the support jaw 234 formed on the motor insulator 230. In particular, since the airtight member 620 is formed thinner than the bent end 621, it is deformed to gradually expand toward the bottom by the pressure of the refrigerant gas and is in close contact with the inner circumferential surface of the seating groove 616. The phenomenon that the refrigerant gas is discharged into the gap between the inner circumferential surface and the airtight member 620 can be prevented in advance. This is as shown in the accompanying FIG. 9.

Accordingly, the gap between the outer circumferential wall 611 of the flow guide 610 and the outer partition 232 of the motor insulator 230 is blocked by the airtight member 620 so that the refrigerant provided into the flow guide 610 As gas is blocked from being discharged to the outside of the outer partition wall 232 of the motor insulator 230, it flows smoothly into the discharge space 101 in the sealed case 100 through the gap between the stator 210 and the rotor 220, Subsequently, it is discharged to the outside through the refrigerant discharge pipe 121 located in the discharge space 101.

In addition, while the above-described refrigerant gas is compressed and discharged, the oil feeder 410 is rotated by the rotation of the rotating shaft 400, so that the oil stored in the oil storage space 102 is stored in the oil passage in the rotating shaft 400 ( It is sprayed on each sliding part and the electric part 200 while being absorbed along the 401).

In addition, the oil sprayed by the sliding part and the electric part flows down the inner wall surface of the sealed case 10, and the oil flow part is the flow path guide 610 and the airtight member 620 of the refrigerant gas. As the inflow is blocked, smooth recovery of the oil is possible.

As a result, in the compressor of the present invention, as the airtight member 620 constituting the flow path separation unit 600 is not formed as an O-ring, but is formed in a pipe structure having rigidity, it is possible to improve the assembling property. That is, since the airtight member 620 is coupled in a manner that is mounted on the flow guide 610, the entire coupling operation can be easily and quickly performed.

In addition, since the airtight member 620 constituting the compressor of the present invention is formed in a pipe shape having rigidity rather than an O-ring made of rubber material, assembly failure such as warping of the airtight member 620 during assembly occurs or, It is possible to prevent the occurrence of malfunctions such as twisting during operation.

In addition, since the flow path separation unit 600 constituting the compressor of the present invention does not form a sealing groove for the installation of the O-ring in the flow guide 610, injection molding is possible because only the stepped seating groove 616 is formed. Therefore, it has the advantage of being advantageous in mass production.

In addition, the flow path separation unit 600 constituting the compressor of the present invention is the outer circumferential wall 611 of the flow guide 610 and the outer partition wall of the motor insulator 230 as the airtight member 620 rises due to the pressure of the refrigerant gas. Since the gap between the gaps 232 is closed, the gap is opened when the compressor is stopped, so that the pressure difference for all parts of the compressor can be quickly resolved.
