Embodiment 1

[0053] figure 1 It is a sectional view of the compression mechanism 4 fixed in the housing 2 . figure 2 for figure 1 XX-X section. image 3 for figure 1 The Y-Y section. Figure 4 for figure 1 The Z-Z section.

[0054] exist figure 1 Among them, the motor 5 and the compression mechanism 4 are fixed in the inner diameter of the housing 2 . The compression mechanism 4 has a cylinder A10 and a cylinder B20, and an intermediate partition plate 30 is provided therebetween. The above-mentioned two cylinders are respectively fixed on the intermediate partition 30 together with the auxiliary bearing 62 and the main bearing 60 by four assembly screws 66 . The eccentric shaft 64 is slidably supported by the main bearing 60 and the sub bearing 62 .

[0055] figure 2 The cylindrical compression chamber A15 provided at the center of the illustrated cylinder A10 is divided into a compression chamber 10a and a compression chamber 10b2 by the piston 14 and two sliding plates 13a a...

Embodiment 2

[0074] Embodiment 2 is related to the technology of adding an intake valve to increase the cooling capacity. Figure 6 and Figure 7 The middle and low-pressure gas suction holes serving as the compression chambers 10a are provided with tapered grooves 19a in the two compression chambers. The tapered groove 19a is a groove inclined toward the compression chamber 10a, and the low-pressure hole 31a of the intermediate partition 30 opens to the tapered groove 19a. In Embodiment 2, tapered grooves 19a are provided in the four compression chambers of cylinder A10 and cylinder B20.

[0075] Figure 8 The central bulkhead 30 shown represents the interface with the cylinder A10. The low-pressure hole 31a and the low-pressure hole 31b opened to the contact surface are fixed with the suction valve 35 by the flat screw 45 on the opening surface. Similarly, an intake valve 35 is also fixed to the low-pressure hole 32 a and the low-pressure hole 32 b provided on the contact surface wit...

Abstract

The invention discloses a dual-cylinder rotation type compressor and a refrigerator with same. The dual-cylinder rotation type compressor comprises a shell and a compression mechanism, wherein the compression mechanism comprises an air cylinder component and two pistons; the air cylinder component comprises two air cylinders; each air cylinder comprises two slide sheet grooves; the two slide sheet grooves of each air cylinder are radially and symmetrically arranged; each slide sheet groove is internally provided with a slide sheet which is suitable for butting against the outer peripheral wall of the corresponding piston; and two slide sheets in each air cylinder are matched with the corresponding pistons so as to define two compression cavities. According to the dual-cylinder rotation type compressor provided by the invention, the slide loss of an eccentric shaft and the failure of the eccentric shaft are reduced, and the noise caused by the vibration and air exhaust of the compressor is reduced.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a double-cylinder rotary compressor and a refrigeration device having the same. Background technique [0002] A rotary compressor that divides the compression chamber into two by arranging two vanes in one cylinder and compresses twice in one revolution has been known for a long time. However, there is no particular advantage over ordinary single-chamber rotary compressors, so they have not been practically used. On the other hand, in air conditioners, the quality requirements for high efficiency, low noise and low vibration are increasing year by year. 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. [0004] For this reason, the present invention proposes a double-cylinder rotary compressor, the sliding loss of the eccentric shaft and the failure of the eccentric shaft are reduc...
