Description
Technical field
The utility model relates to the acoustic filters of the compressor for the refrigeration system used in household electrical appliance.The present invention
Purpose disclose a solution, the solution with compared with other filters of the prior art have higher sound
/ thermodynamic efficiency structure.
Background technique
As it is known by the man skilled in the art, reciprocating compressor includes that can be held by continuously changing the inside of discharge chambe
Product carrys out the electromechanical assembly of compression work fluid.Hermetic compressor is applied to refrigeration system mostly.
Permitted in multifunctional variable present in the hermetic compressor, it is known that solution be intended to optimize by compression mechanism
The temperature of the working fluid of sucking and/or it is intended to optimize the noise level that generates during compressor operation.
Currently available technology includes multiple schemes, and the multiple scheme is designed specifically to the temperature of the working fluid of optimization sucking
Degree.For example, document PI 1100416 describes application of the preevaporator inside the air-tight casing of compressor, main purpose is
Reduce the temperature of compression mechanism or the temperature of the working fluid by compression mechanism sucking.
Currently available technology includes multiple schemes, and the multiple scheme is designed specifically for use in decaying and is recycled and arranged by sucking
The microseismic noise of generation is recycled out, and in known scheme, the scheme of referred to as sound absorption filter is shown one's talent.Sound is inhaled
Receiving filter is widely known to those skilled in the art and is widely described in particular technology document.Filtering
The acoustic efficiency of device is obtained by the adoptable various geometrical constructions of the equipment.In this way, according to selection or the geometrical construction proposed,
The pulsation of pressure can be decayed by the effect of passive elimination.
However, currently available technology does not include any such scheme, its own has and can independently optimize sucking
The temperature and sucking circulation of working fluid and discharge recycle the feature of the decaying of generated microseismic noise.In this scene
Under, the utility model discussed is come into being.
Utility model content
The all purposes of the utility model discussed is realized by reciprocating compressor absorbing filter, described reciprocating
Compressor absorbing filter includes at least one access road;At least one exit passageway;It is fluidly connected to access road and goes out
At least one Noise attenuating room in mouth channel;It is fluidly connected at least one resonant chamber of access road;Be fluidly connected into
At least one inlet nozzle in mouth channel and at least one oil drain passage for being fluidly connected to Noise attenuating room.
According to the utility model discussed, anechoic chamber includes at least one vertical sound-proof wall and is fluidly connected to out wherein
At least one tubular structure in mouth channel.
In addition, resonant chamber is limited by least one resonatron for being connected to access road according to the utility model discussed.
The internal capacity of resonant chamber is formed by two parts main body of acoustic filter itself.
Moreover, inlet nozzle includes main body, and the entrance of the main body is relative to refrigerant according to the utility model discussed
The mainstream of fluid stream has shunting section and/or confluence section.
Detailed description of the invention
The utility model discussed will especially be described in detail on the basis of following illustrative embodiments, in which:
Fig. 1 schematically shows the sound absorption filter seen from front;
Fig. 2 schematically shows total screenshots of sound absorption filter;And
Fig. 3 schematically shows the sound absorption filter laterally seen.
Specific embodiment
According to the utility model discussed, disclose a kind of reciprocating compressor sound absorption filter, specifically include that into
Mouth channel (11), exit passageway (12), Noise attenuating room (21), resonant chamber (22), inlet nozzle (6) and oil drain passage (7).
Preferably, reciprocating compressor sound absorption filter two parts main body made of polymer material is formed,
Cladding injection technique is engaged through between two parts main body to execute.
Noise attenuating room is fluidly connected to the access road (11) and the exit passageway (12).In the inside of Noise attenuating room
It is provided with vertical sound-proof wall (3), and tubular structure (4) is fluidly connected to the exit passageway (12).
Resonant chamber (22) is fluidly connected to the access road (11) by resonatron (51).This resonant chamber is filtered by sound
The two-part structure itself of device (5) limits.
More specifically, the resonant chamber (22) of reciprocating compressor sound absorption filter or the distinguishing characteristics of resonator are it
It reaches the inside of acoustic filter and especially proximate to Noise attenuating room (21), and is arranged in above access road (11), it is described
Resonant chamber is fluidly connected to access road.The total volume and/or shape and/or size of resonant chamber (22) can be varied so that
The resonant chamber (22) covers specific sound frequency, makes it possible to optimize reduction compressor work energy noise.
Inlet nozzle (6) is preferably modular, is fluidly connected to access road (11).Inlet nozzle (6) packet
Main body is included, the entrance of the main body has shunting section and/or confluence section relative to the mainstream of refrigerant fluid stream.
More specifically, the part of the shunting section of inlet nozzle (6) includes fluid inlet itself, the area of the fluid inlet
Less than fluid guidance field (doab).The presence of the part of shunting section is used for directly from the suction inlet collection work stream of compressor
Body, and define the barrier of the sucking closing working fluid in the internal environment limited by the closing shell of compressor.Due to
The sucking power of reciprocating compressor is substantially constant (being pulsed with high-frequency), so relative to the stream flowed from mainstream
The temperature of dynamic temperature, " sucking fluid " has insufficient time to largely improve.In this way, the volume of nozzle is final
It works under " low " temperature as working fluid reservoir.
Oil drain passage (7) is fluidly connected to the Noise attenuating room (21).
Have been described and illustrate the various embodiments of discussed utility model, it should be appreciated that the protection model discussed
It encloses and may include other possible modifications, which is only limited by the content of claim, and the hand including that may be equal with it
Section.
