Embodiment 1

[0036] Such as figure 1 As shown, the rotary compressor 1 accommodates an inverter motor 4 capable of changing the rotation speed and a compression mechanism part 5 in a housing 2, and the outer periphery of the stator 4a constituting the motor 4 and the outer periphery of the cylinder 10 arranged at the center of the compression mechanism part 5 are fixed. On the inner peripheral wall of the housing 2. The casing 2 is composed of a cylindrical casing 2a, an upper end plate 2b and a lower end plate 2c welded to its upper and lower ends. In addition, the bottom of the casing 2 is provided with an oil storage tank 8 for storing oil.

[0037] The compression mechanism unit 5 includes a piston 60 housed in the compression chamber 10 a of the cylinder 10 , a slide plate (not shown) reciprocating together with the piston, a main bearing 40 and a sub bearing 45 arranged on the cylinder, and a crankshaft 30 . Crankshaft 30 includes main shaft 32 and counter shaft 36 in sliding engag...

Embodiment 2

[0047] Figure 4 In the oil separator 20 shown, the cylindrical case 21 used in the first embodiment is omitted. Through the top plate 27 and the rivets 28, the oil filter 22 is fixed directly to the rotor 4b. Furthermore, the inlet of the exhaust pipe 3 is opened at the center of the oil separator 22 .

[0048] Compared with Example 1, Example 2 does not need to change the design of the crankshaft 30, and it is easy to use the oil separator 20. Furthermore, the functions of the oil separator 20 are basically the same. Also, if necessary, append figure 2 filter box 22a.

[0049] The multi-cylinder rotary compressor of the present invention can be mounted on an air conditioner, a refrigeration device, a water heater, a vehicle-mounted refrigeration system, a vehicle-mounted air conditioner, and the like.

Abstract

The invention discloses a rotary compressor. A rotary compressing mechanism part and a motor are contained inside a sealed housing connected to a vent-pipe. The motor contains a stator and a rotor. The compressing mechanism part comprises a cylinder provided with a compression chamber, a crankshaft and an oil separator, wherein the cylinder is provided with a piston and a slip sheet; the crankshaft is driven by the rotor and eccentrically rotates the piston; and the oil separator rotates together with the crankshaft or the rotor and is provided with an oil filter. High pressure gas discharged out of the compression chamber flows through the oil filter and then flows into the vent-pipe. According to the rotary compressor of the embodiment, high pressure gas discharged out of the compression chamber can undergo oil separation and oil filtration. Thus, amount of oil in the high pressure gas discharged out of the vent-pipe is greatly reduced, amount of oil inside the rotary compressor is guaranteed, failure rate of the rotary compressor is decreased, and reliability and efficiency of the rotary compressor are boosted.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a rotary compressor. Background technique [0002] The internal pressure of the casing is the high-pressure rotary compressor, and the high-pressure gas discharged from the compression chamber contains a large amount of oil, that is, the oil is mixed into the refrigerant discharged from the compressor to the refrigeration cycle, so the amount of oil inside the compressor changes, and the casing The oil content inside is greatly reduced. As a result, not only failure of the compressor is caused, but also a decrease in efficiency performance. This problem is more obvious on rotary compressors operating at high speeds above 90rps. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a rotary compressor, which can perform oil separation and oil fil...
