Abstract
The utility model discloses a kind of inhaling silencer structures improving compressor oil circulation amount, including upper cover, lower casing, air intake duct and escape pipe, upper cover with lower casing is closed is connected, escape pipe and air intake duct are respectively arranged in upper cover and lower casing, the bottom of lower casing is equipped with tonifying Qi hole and oil dripping hole, the outside of oil dripping hole is funnel type edge, and the bottom at funnel type edge is equipped with outlet.By oil dripping hole and funnel type edge, the lubricating oil for being attached to silencer internal wall face can be allowed to flow downward by gravity, be discharged from oil dripping hole, returned in compression case body；And funnel type edge increases the flow resistance that mist of oil is sucked with refrigerant from oil dripping hole, the oil in shell after heating is avoided to enter inhaling silencer by oil dripping hole, it prevents suction temperature from overheating, can effectively improve the oily internal circulating load of compressor, improve the matching performance of compressor.
Description
Technical field
It is specifically a kind of to be applied to refrigerator sealed refrigeration the utility model is related to arrive technical field of refrigeration compressors
The inhaling silencer for improving oily internal circulating load of frequency-changeable compressor.
Background technology
Refrigerator compressor oil internal circulating load is an important indicator of refrigerator refrigeration system performance.When refrigerant oil-bearing amount is excessive
When, refrigerating efficiency is influenced, meanwhile, oil film can be formed on the inside of heat exchanger, reduce heat transfer efficiency.Lubricating oil enters freezer compressor
Cylinder mainly passes through two kinds of approach：First, the reciprocating motion with piston enters cylinder；Second is that disappearing in semi-direct or indirect air-breathing
In sound device breathing process, the lubricating oil of atomization sucks cylinder with refrigerant from the air entry and oil dripping hole of silencer.Especially exist
In the high rotating speed operational process of frequency-changeable compressor, lubricating oil temperature increases, movement vibrates the atomization that can aggravate lubricating oil, a large amount of mist of oils
As refrigerant is sucked from oil dripping hole and air entry, to increase oily internal circulating load, compressor Energy Efficiency Ratio is influenced.In addition, with change
The reduction of frequency compressor height, inhaling silencer oil dripping hole can cause to come from shell relatively closer to shell bottom lubricating oil liquid level
The lubricating oil at bottom is easier in refrigerant suction silencer, influencing oily internal circulating load.In Publication No. CN102720652A
State's application for a patent for invention proposes a kind of compressor inhaling silencer reducing heat exchange and oil drain quantity, is connected in air inlet pipe
There is the bellows in horn-like structure, can effectively solve the problems, such as that mist of oil from air entry suction silencer, promotes compressor Energy Efficiency Ratio,
But assembly is complicated, and noise is higher, and during the operation of the compressor, bellows easily ruptures, and influences compressor reliability.
Invention content
The technical problem to be solved by the utility model is to propose that one kind can effectively reduce mist of oil to suck from oil dripping hole, from
And improve the inhaling silencer structure of compressor oil circulation amount.
In order to solve the above technical problems, a kind of inhaling silencer structure improving compressor oil circulation amount of the utility model
Including upper cover, lower casing, air intake duct and escape pipe, the upper cover with lower casing is closed is connected, the escape pipe and air intake duct are set respectively
In in the upper cover and lower casing, the bottom of the lower casing is equipped with tonifying Qi hole and oil dripping hole, and the outside of the oil dripping hole is funnel type
The bottom at edge, the funnel type edge is equipped with outlet.
A kind of above-mentioned inhaling silencer structure improving compressor oil circulation amount, the oil dripping hole are set to the lower casing bottom
The extreme lower position in portion, and in the region at the funnel type edge.
A kind of above-mentioned inhaling silencer structure improving compressor oil circulation amount, the funnel outside the oil dripping hole
The outlet at bottom diameter at type edge is less than the diameter of the oil dripping hole, and the top diameter at the funnel type edge is more than the oil dripping
The diameter in hole, the height at the funnel type edge are more than the diameter of the oil dripping hole.
A kind of above-mentioned inhaling silencer structure improving compressor oil circulation amount, the center of the oil dripping hole and the leakage
The center at bucket type edge is located at same axis.
For the utility model as a result of above-mentioned technical pattern, it can generate following beneficial technique effect：Lubricating oil
Mist is as in refrigerant suction silencer, most of mist of oil is attached to silencer internal wall face, by oil dripping hole and funnel type edge,
The lubricating oil for being attached to silencer internal wall face can be allowed to flow downward by gravity, be discharged from oil dripping hole, compressor is returned to
In shell；Meanwhile funnel type edge increases the flow resistance that mist of oil is sucked with refrigerant from oil dripping hole, avoids heating in shell
Oil afterwards enters inhaling silencer by oil dripping hole, prevents suction temperature from overheating, can effectively improve the oily internal circulating load of compressor（It is special
It is not under the high rotating speed operation of frequency-changeable compressor, oil cycle improvement effect becomes apparent）, improve the matching of compressor
Energy.
Description of the drawings
Fig. 1 is the external structure schematic diagram of the utility model inhaling silencer structure；
Fig. 2 is the bottom substance schematic diagram of the utility model inhaling silencer structure；
Fig. 3 is the partial enlargement structural representation at oil dripping hole in Fig. 1.
Specific implementation mode
As shown in Figure 1, the utility model inhaling silencer structure includes upper cover 1 and lower casing 2, it is close by welding wire between the two
Envelope.Upper cover 1 is equipped with escape pipe 4, and lower casing 2 is equipped with air intake duct 3.Expanding may be used in inhaling silencer, can also adopt
With resonant.One side bottom of lower casing 2 is provided with tonifying Qi hole 5, and the bottom of lower casing 2 is equipped with oil dripping hole 6（Please refer to Fig. 3 institutes
Show）, it is convenient for inhaling silencer tonifying Qi and oil extraction.
Shown in Fig. 2 and Fig. 3, the extreme lower position in 2 bottom of lower casing is arranged in oil dripping hole 6, and outside is funnel type
Edge 7, a diameter of 1mm of oil dripping hole 6, and in 7 region of funnel type edge（In present embodiment the center of oil dripping hole 6 and
The center at funnel type edge 7 is located on same axis, can also bias certainly）.The outlet at bottom 9 at funnel type edge 7 it is a diameter of
0.8mm is less than 6 diameter of oil dripping hole.A diameter of 4mm at the top 8 at funnel type edge 7（More than the diameter of oil dripping hole 6）, highly it is
4mm（More than the diameter of oil dripping hole 6）, the flow resistance that mist of oil is sucked with refrigerant from oil dripping hole 6 is increased, compression case is avoided
The oil after heating enters inhaling silencer by oil dripping hole 6 in vivo, prevents suction temperature from overheating.
The utility model structure both can be applied on expansion muffler, can also be applied on resonator muffler.
