Embodiment 1
[0039] figure 1 The structure of the rotary compressor 1 of this invention, and the refrigeration cycle apparatus of the air conditioner connected with the rotary compressor 1 are shown. The sealed case 2 accommodates the compression mechanism part 5, the motor 6, and the lubricating oil 8 at the bottom. The outer circumference of the cylinder 10 of the compression mechanism part 5 is fixed on the inner circumference of the sealed housing 2 by spot welding, and the circular compression chamber 11 at the center of the cylinder 10 is sealed by the main shaft plate 21 of the main bearing 20 and the auxiliary shaft plate 26 of the auxiliary bearing 25 .
[0040] The crankshaft 40 is in sliding fit with the main bearing 20 and the auxiliary bearing 25 , and the eccentric shaft 40 a of the crankshaft 40 is in the compression chamber 11 to drive the piston 15 to revolve. The front end of the slide plate 16 reciprocating in the slide plate groove 14 of the air cylinder 10 abuts again...
Embodiment 2
[0073] Figure 12 The rotary compressor 101 shown is characterized in that a bypass device 30A and a bypass device 30B are respectively provided on both the main shaft plate 21 and the sub shaft plate 26 . The bypass device 30B of the subshaft plate 26 is covered by the sub muffler 28 .
[0074] After the rotary compressor 101 is started, the high-pressure gas of the main muffler 23 on the main shaft plate 21 is discharged from the compression chamber 11 , and is discharged into the inside of the sealed casing 2 through the muffler exhaust hole 23 a. At this time, the internal pressure of the sub muffler 28 becomes equal to the pressure of the main muffler 23 through the through hole 43 in the compression mechanism portion 5 . In addition, the high-pressure gas discharged into the sealed case 2 passes through the motor 6 and is discharged from the exhaust pipe 3 to the condenser 50 as in the first embodiment.
[0075] Same as Embodiment 1, when the pressure difference (ΔP) b...
Embodiment 3
[0079] Figure 13 A design example in which the bypass device 30 is provided on the outer peripheral surface of the cylinder 10 is shown. The lower side of the bypass hole 33 is opened to the inside of the suction pipe 13 . In addition, the U-shaped groove 12a necessary in Embodiment 1 can be omitted.
[0080] Compared with Example 1, in Example 3, since the upper side of the bypass hole 33 is outside the main muffler 23, (1) the pressure increase (Pd+) at the time of compressor startup cannot be utilized. Therefore, the time to reach the pressure of the condenser 50 after the compressor starts is slightly delayed. (2) The lubricating oil 8 may flow into the bypass hole 33 . However, there is no problem in a design with a small amount of oil.
[0081] Combine below Figure 1-Figure 13 A rotary compressor according to an embodiment of the present invention will be described in detail.
[0082] refer to figure 1 As shown, the rotary compressor according to the embodiment ...
