Abstract

PURPOSE:To contrive the reduction of lubricating oil discharged to the outside of a compressor by introducing an outflow of lubricating oil from a bearing in an electric motor side of a compressor groove passing through a flow path, provided in the inside of the compressor groove, to a reservoir part. CONSTITUTION:By an oil pump on a shaft 17, lubricating oil is supplied passing through an outlet port 18 to an upper bearing 20. The lubricating oil is allowed to flow in a sliding part mainly from a helical groove 22, performing lubrication. Thereafter, the lubricating oil in the helical groove 22 and the sliding part reaches an oil reservoir 23 formed in an upper end of the upper bearing 20. Here the lubricating oil, by the gravitational force, is allowed to flow in a flow path 24 and out from an opening part in a bottom part of the upper bearing 20 passing through the flow path 24, because the lubricating oil is returned to an oil reservoir part 14 just below the opening part, the lubricating oil, atomized by rotating a rotor 16 in the upper end of the upper bearing 20, is decreased.

以下、図面を参照しながら説明する。This will be explained below with reference to the drawings.

A separation plate 7 is fixed to a support rod 8 inserted into the upper part of the rotor 5. 9 is a discharge pipe located at the center of the separation plate 7. Reference numeral 10 denotes lubricating oil, which is stored around the compressor section 3.

以上のように構成された圧縮機について、以下その動作
について説明する。The operation of the compressor configured as above will be explained below.

ている。In the compressor section 3 driven by the electric motor section 2, gas refrigerant is sucked, compressed, and discharged into the upper space of the compressor section 3. On the other hand, the lubricating oil 10 supplied to the sliding parts of the compressor part 3 by the oil pump built in the compressor part 3 flows out from the bearing in the upper part of the compressor part 3, and 1li
II+6 and the rotation of the rotor 5 atomizes. Then, the lubricating oil 10 is mixed into the gas refrigerant discharged from the compressor section 3 and reaches the upper space of the electric motor section 2. Here, in the flow path leading to the discharge pipe 9, the atomized lubricating oil 10
is separated from the gas refrigerant by the centrifugal action of the separation plate 7, and only the gas refrigerant is discharged from the discharge pipe 9.

た。However, with the above configuration, as the rotation speed of the compressor increases, the amount of oil pumped by the oil pump increases, and the amount of lubricating oil atomized increases accordingly, causing the separation plate to increase. This exceeds the lubricating oil separation capacity of the compressor, and the amount of lubricating oil discharged to the outside of the compressor increases. As a result, there was a shortage of lubricating oil inside the compressor, resulting in insufficient lubricating oil supply to the sliding parts of the compressor, leading to increased wear on the sliding parts due to metal contact, etc. .

ある。Means for Solving the Problems In order to solve the above problems, the compressor of the present invention includes an electric motor, a compression mechanism driven by the electric motor, a shaft connecting the electric motor and the compression mechanism, and a shaft inside the compression mechanism. The lubricating oil flowing out from the bearing on the electric motor side of the compression mechanism is formed by a flow path that guides the lubricating oil flowing out from the bearing on the motor side of the compression mechanism to the lubricant Mu reservoir located around the compression mechanism.

Returns unaffected to the lubricating oil reservoir around the compression mechanism.

8 and is supplied to the upper bearing 20. The lubricating oil mainly flows into the sliding portion through the helical groove 22 and performs lubrication. Thereafter, the lubricating oil in the helical groove 22 and the sliding portion reaches an oil reservoir 23 formed at the upper end of the upper bearing 20. Here, the lubricating oil flows into the flow path 24 by gravity, passes through the flow path 24, flows out from the opening at the bottom of the upper bearing 20, and is returned to the lubricant oil reservoir 14 immediately below, so that the upper bearing 20 At the upper end of the rotor 16, the amount of lubricating oil atomized by rotation of the rotor 16 decreases. However, in high-speed operation, the amount of oil pumped by the oil pump increases in proportion to the square of the compressor rotation speed, but by providing multiple flow paths 24, overflow of lubricating oil from the upper bearing in the oil sump 23 is prevented. can. Alternatively, overflow can also be prevented by sufficiently reducing the gap between the rotor 16 and the upper bearing 20 and increasing the passage resistance. That is, even during high-speed operation, atomization of the lubricating oil flowing out from the bearing 20 can be prevented. As a result, the amount of lubricating oil discharged to the outside of the compressor is reduced, and sufficient lubricating oil can be secured inside the compressor even during high-speed operation.

In addition, air conditioners can also be made smaller by improving reliability and eliminating the need for oil separators, and by reducing the influence of lubricating oil on the heat exchangers that make up air conditioners. It has the effect of improving the capacity and efficiency of air conditioners.

Since the lubricating oil that has reached this level is not agitated by the rotor 15 because of the lid 28, it is not atomized. Although there is a gap between the lid 28 and the shaft 17, it is sufficiently small compared to the passage area of the flow path 24, and most of the lubricating oil flows into the flow path 24. Therefore, axis 17
All of the lubricating oil that has flowed out from the upper bearing 20 can be reliably returned to the reservoir 14 without being affected by the rotor 15 or the discharged refrigerant. As a result, the amount of lubricating oil discharged to the outside of the compressor can be further reduced.

The lubricating oil is guided into the vane groove 31 to lubricate the vane 30, and then directly returned to the lubricating oil reservoir from the lower bearing 29. During transient operations such as starting an air conditioner or defrosting, the amount of lubricating oil in the reservoir 14 temporarily decreases due to forming, causing a drop in the oil level, but the lubrication oil supplied by the oil pump and reaching the oil reservoir 23 The oil reaches the vane groove 31 through the flow path 24' without being atomized by the rotor 16, and oil is collected in the vane 30. Therefore, the reliability of the compressor during transient operation can be improved.
