Problems solved by technology

However, if the positional relationship between the protruding container and the cylinder deviates from the normal position, the positional relationship between the vanes positioned based on the cylinder and the spring positioned based on the protruding container also deviates from the normal position.

Embodiment approach 1

[0021] [hermetic compressor 100]

[0022] figure 1 It is a schematic vertical cross-sectional view of the hermetic compressor according to the first embodiment. figure 2 Yes figure 1 A-A line cross-sectional schematic diagram. in, figure 2 Indicates the state where the A-A line cross-section is rotated 90 degrees counterclockwise.

[0023] The hermetic compressor 100 is one of elements constituting a refrigeration cycle used in, for example, an air conditioner, a refrigerator, a refrigerator, a vending machine, a water heater, or the like. The hermetic compressor 100 is a double rotary compressor having two compression chambers. The hermetic compressor 100 includes a hermetic container 10 , a motor mechanism part 20 and a compression mechanism part 30 accommodated in the hermetic container 10 . Moreover, the hermetic compressor 100 has the accumulator 13 outside the hermetic container 10 , and has the suction pipe 11 connecting the hermetic container 10 and the accumul...

Embodiment approach 2

[0103] [hermetic compressor 110]

[0104] Figure 8 It is a schematic longitudinal sectional view of the hermetic compressor according to the second embodiment. right and Figure 1 to Figure 7 The parts of the hermetic compressor 100 having the same structure are marked with the same reference numerals. Items not particularly described in the hermetic compressor 110 according to Embodiment 2 are described with the same reference numerals for the same functions and structures as in the hermetic compressor 100 according to Embodiment 1.

[0105] In the hermetic compressor 100 according to the first embodiment, the number of the protruding containers 50 is always one regardless of the number of the cylinders 31 arranged in the airtight container 10 . On the other hand, in the hermetic compressor 110 according to the second embodiment, the number of the protruding containers 50 changes according to the number of the cylinders 31 arranged in the airtight container 10 . That is,...

Embodiment approach 3

[0114] Figure 9 It is a figure which shows the refrigerant circuit of the refrigeration cycle apparatus which concerns on Embodiment 3. FIG.

[0115] The refrigeration cycle device 60 includes a hermetic compressor 61 , a condenser 62 , an expansion valve 63 as a decompression device, and an evaporator 64 . The hermetic compressor 61 is constituted by the hermetic compressor 100 of the first embodiment or the hermetic compressor 110 of the second embodiment. The gas refrigerant discharged from the hermetic compressor 61 flows into the condenser 62, exchanges heat with the air passing through the condenser 62, becomes a high-pressure liquid refrigerant, and flows out. The high-pressure liquid refrigerant flowing out of the condenser 62 is decompressed by the expansion valve 63 to become a low-pressure gas-liquid two-phase refrigerant, and flows into the evaporator 64 . The low-pressure gas-liquid two-phase refrigerant flowing into the evaporator 64 exchanges heat with the ai...

Abstract

This hermetic compressor is provided with: a hermetic container; the hollow cylinder body is accommodated in the sealed container; a rotary piston that eccentrically rotates along the inner peripheral wall of the cylinder; a vane that reciprocates in a vane groove provided in the cylinder in the radial direction of the cylinder; and a spring that urges the vane toward the side where the rotary piston is disposed. The hermetic compressor is further provided with: a protruding container which is provided so as to protrude from the hermetic container in the radial direction of the cylinder on the opposite side from the cylinder, and which forms a hermetic space by having one end thereof joined to the hermetic container and communicating with the inside of the hermetic container; and a spring guide which is disposed in the sealed space of the protruding container and in which a spring is fixed. An insertion hole is formed in the outer peripheral wall of the cylinder, and one end of the spring guide is inserted into and fixed to the insertion hole of the cylinder.

Description

technical field [0001] The present invention relates to a hermetic compressor used in an air conditioner, a refrigerator, a refrigerator, or the like, a refrigeration cycle device, and a method for manufacturing the hermetic compressor. Background technique [0002] The hermetic compressor includes an annular cylinder housed in a hermetic container, a rotary piston eccentrically rotating within the cylinder, and a vane that reciprocates in a vane groove provided in the cylinder. The vane is biased by the spring so that the vane tip portion is always in contact with the rotary piston, thereby partitioning the space inside the cylinder into a low-pressure space and a high-pressure space. Then, the eccentric movement of the rotary piston in the cylinder reduces the volume of the low-pressure space to become a high-pressure space, and compresses the refrigerant sucked into the cylinder. [0003] In such a hermetic compressor, a spring for urging the vanes is accommodated in a s...
