Description
Technical field
The utility model relates to a kind of air condition compressor, and especially a kind of relief opening has the room air conditioner scroll compressor of anti feedback device.
Background technique
Scroll compressor is very a kind of rapidly idle call compressor of development in recent years, it has the rotating speed height, proper functioning under the deep-fried twisted dough sticks spare can lacked, long service life, easy to maintenance simple, but because its complex structure, difficulty of processing is big, and cost of production is higher relatively and can't be extensive use of in room air conditioner.And constantly perfect along with processing technique in recent years, its cost is more and more lower, so its ratio of using in the particularly high-grade air conditioner of room air conditioner is more and more higher.
Because the structural feature of scroll compressor, its exhaust pressure is to be periodically variable, the pressure of relief opening also is to be periodically variable, when compressor is in the exhaust low pressure stage, pressurized gas in the pipeline will inevitably pour in down a chimney in compressor from relief opening, and meet with the pressurized gas of discharging in the compressor subsequently, producing exhaust noise, therefore must be overcome.
Summary of the invention
The purpose of this utility model is the room air conditioner scroll compressor that a kind of relief opening that prevents that the pressurized gas in the pipeline from refluxing of design has the anti feedback device.
The technical solution of the utility model is:
A kind of relief opening has the room air conditioner scroll compressor of anti feedback device, comprise casing 1 and be installed in motor 2 in the casing 1, bent axle 3, Moving plate 4, quiet dish 5, bent axle 3 is sleeved on the rotor of motor 2, its upper end links to each other with Moving plate 4, it is relative with lubricating oil bath that motor 2 is passed in its lower end, Moving plate 4 inserts in the quiet dish 5, be formed with low-pressure cavity between quiet dish 5 and the Moving plate 4, middle chamber and the hyperbaric chamber of pressing, have high pressure gas hole 6 on the quiet dish 5, this high pressure gas hole 6 communicates with exhaust cavity 7, exhaust cavity 7 is connected with relief opening 8, it is characterized in that being equipped with in the relief opening 8 anti feedback device 9.
Described anti feedback device 9 is made up of connecting plate 901, connecting rod 902, exhaust screen 903, Returnning spring 904, Returnning spring 904 is sleeved on the outer end of connecting rod 902, one end and exhaust screen 903 offset, limiting stopper 905 on the other end and connecting rod 902 outer ends offsets, connecting plate 901 links to each other with the inner of connecting rod 902, exhaust screen 903 is sleeved on the connecting rod 902, and connecting plate 901 and exhaust screen 902 lay respectively at two ends of the small-bore through hole 906 in the relief opening 8 and the relief opening inwall by these small-bore through hole 906 2 ends is spacing.
The beneficial effects of the utility model:
Simple in structure, manufacturing, easy for installation can prevent return-air effectively, reduces exhaust noise, the workmanship of improvement.
