Abstract
The utility model discloses a kind of muffler structures of piston compressor, including muffler lid, muffler box and muffler partition, muffler lid is connected with muffler box, muffler partition is placed in muffler lid and muffler box, the both ends of muffler partition are connected on muffler lid and muffler box, muffler partition is equipped with intubation, and intubation is equipped with oil leak slot.The utility model had not only been able to satisfy oil leak function, but also can simply and effectively enhance the acoustic attenuation performance of low-frequency range in muffler, reduce because in existing structure aperture be connected to due to caused by muffler acoustic attenuation performance loss.
Description
Technical field
The utility model relates to arrive Compressor Technology field, specifically a kind of air-breathing applied to piston compressor
Muffler structure.
Background technique
Compressor is the heart of refrigerator, it operates band by motor from the refrigerant gas of air intake duct sucking low-temp low-pressure
After piston compresses it, to the refrigerant gas of exhaust pipe discharge high temperature and pressure, power is provided for refrigeration cycle, thus
Realize compression → condensation → expansion → evaporation (heat absorption) refrigeration cycle.
Currently, the compressor silencer of domestic refrigerator mostly uses expansion chambers muffler.Different from dissipative muffler, resistance disappears
Sound device does not use sound-absorbing material, is mainly eliminated the noise using the size of acoustic reactance, connects resonant cavity by the mutation or side of pipeline section
Deng the change for causing during acoustic propagation impedance, reflection, the interference phenomenon of sound wave are generated, to reduce by the outside spoke of silencer
The sound energy penetrated, achievees the purpose that noise elimination.Expansion chambers muffler is multi-cavity series connection under normal conditions, and there are partitions between chamber and chamber.
Refrigeration oil is sucked in compressor operational process in order to prevent, leads to oil accumulation in muffler, influences muffler performance, it can be on partition
Increase oil leaking hole.But there are still following disadvantages for the air suction silencer: since there are oil leaking hole, the pore channels meetings between chamber and chamber
Influence the acoustic attenuation performance of low-frequency range in muffler.
Summary of the invention
The technical problem to be solved by the utility model is to propose that one kind had not only been able to satisfy oil leak function, but also can be simple and effective
Ground enhance acoustic attenuation performance piston compressor muffler structure, with reduce because in existing structure aperture be connected to due to caused by disappear
The loss of sound device acoustic attenuation performance.
In order to solve the above technical problems, a kind of muffler structure of piston compressor of the utility model includes muffler
Lid, muffler box and muffler partition, the muffler lid are connected with the muffler box, and the muffler partition is placed in described
In muffler lid and the muffler box, the both ends of the muffler partition are connected to the muffler lid and muffler box
On, the muffler partition is equipped with intubation, and the intubation is equipped with oil leak slot.
A kind of muffler structure of above-mentioned piston compressor, the muffler partition are equipped with reinforcing rib.
A kind of muffler structure of above-mentioned piston compressor, the muffler partition are equipped with protection sleeve pipe, the guarantor
Protecting pipe is located at the outside of the intubation.
A kind of muffler structure of above-mentioned piston compressor, it further includes having steel wire, and the muffler is covered equipped with ring
Slot, the muffler box are equipped with boss, and the steel wire is placed in the annular groove, and the boss is placed in the annular groove, is passed through
The muffler lid and the muffler box are linked together after the steel wire weld.
A kind of muffler structure of above-mentioned piston compressor, the muffler is covered to be set respectively on the muffler box
There is septalium, one end of the muffler partition is placed in the septalium that the muffler covers, the muffler box
The septalium is caught in the other end of the muffler partition.
The utility model is due to using above-mentioned technical pattern, on the muffler partition between two chamber of air suction silencer
Additional pore channels are not provided with, thus can effectively promote the acoustic attenuation performance of low-frequency range in muffler.Meanwhile it is close using this
Seal structure neither increases production cost, and simple process, is suitble to produce in enormous quantities and use.
Detailed description of the invention
Fig. 1 is the side, sectional structural schematic diagram of the utility model muffler；
Fig. 2 is the schematic view of the front view of partition in the utility model muffler.
Specific embodiment
As shown in Figure 1, the muffler structure of the utility model piston compressor include muffler lid 1, muffler box 2,
Muffler partition 3 and steel wire 4.Muffler lid 1 be equipped with annular groove 11 and septalium 12, muffler box 2 be equipped with boss 21 and every
Board slot 22.Steel wire 4 is placed in annular groove 11, for welding.One end of muffler partition 3 is placed in the septalium 12 on muffler lid 1
Interior, the boss 21 of muffler box 2 is placed in annular groove 11, and the septalium 22 of muffler box 2 is caught in the other end of muffler partition 3,
By steel wire weld by above-mentioned component combination together.
As shown in Fig. 2, muffler partition 3 is equipped with reinforcing rib 5, protection sleeve pipe 7 and intubation 8.Reinforcing rib 5 plays reinforcement and disappears
Sound device partition 3, promotes the effect of its intrinsic frequency, may also function as certain Oil Guide function.Intubation 8 is equipped with oil leak slot 6, can rise
To the effect of oil leak, (one or more is can be set in oil leak slot 6；It can also be uniformly distributed with random distribution).Protection sleeve pipe 7
In the outside of intubation 8, the air-flow of 6 side of oil leak slot in intubation 8 can be stablized.
