Traditional inhaling silencer is all to adopt circular intakeport, and its circulation area is limited, thereby causes refrigerating capacity not enough, the defect that input power is too high, silencing apparatus inside does not have demarcation strip, causes soundproof effect undesirable, can not meet refrigerator user and fall low noise usage requirement.
Model utility content
The purpose of this utility model is to provide a kind of inhaling silencer of compressor noise-reduction, can increase circulation area, raising refrigerating capacity, the reduction input power of intakeport, improves soundproof effect, thereby meets people's usage requirement.
The technical solution of the utility model is as follows:
An inhaling silencer for compressor noise-reduction, comprises inhaling silencer main body, in inhaling silencer main body, has intakeport, it is characterized in that: described intakeport, for abnormity mouthful, is provided with demarcation strip in described inhaling silencer body interior.
As preferably, the shape and structure of described abnormity mouthful is to be formed by straightway, the arc section of hypomere, the waveform curved section end-to-end of epimere of left and right section.
As preferably, described demarcation strip is shaped as T-shaped, and anechoic room is divided into three air-breathing noise elimination cavities.
As preferably, described air-breathing noise elimination cavity comprises the first air-breathing noise elimination cavity, the second air-breathing noise elimination cavity and the 3rd air-breathing noise elimination cavity; Described the first air-breathing noise elimination cavity is communicated with by air intake passage with the 3rd air-breathing noise elimination cavity with the second air-breathing noise elimination cavity, the second air-breathing noise elimination cavity.
As preferably, described air-breathing silencing cavity is the cavity consisting of working of plastics.
As preferably, described air intake passage diameter is 6mm.
In inhaling silencer inside, add demarcation strip, formed independently noise-reducing structure, concrete noise reduction principle is: refrigerant gas enters the first air-breathing noise elimination cavity and through being communicated with the air intake passage of the first air-breathing noise elimination cavity and the second air-breathing noise elimination cavity, enters the second air-breathing noise elimination cavity again, after the second air-breathing noise elimination cavity buffering, by being communicated with the air intake passage of the second air-breathing noise elimination cavity and the 3rd air-breathing noise elimination cavity, enter the 3rd air-breathing noise elimination cavity again, finally enter compresser cylinder, by three grades of air-breathing noise elimination cavities, expand step by step decompression and reduced the pulsation of gas, thereby reduced suction noise.
The beneficial effects of the utility model: the utility model is simple in structure, be convenient to processing, with low cost, can increase the circulation area of intakeport, reduces intake resistance, strengthens soundproof effect, thereby improves compressor efficiency, meets people's usage requirement.

Embodiment
Embodiment:
As shown in Fig. 1～Fig. 5, a kind of inhaling silencer of compressor noise-reduction, comprise inhaling silencer main body 1, in inhaling silencer main body 1, there is intakeport 2, described intakeport 2 is abnormity mouthful, and the shape and structure of abnormity mouthful is to be formed by straightway, the arc section of hypomere, the waveform curved section end-to-end of epimere of left and right section; In described inhaling silencer main body 1 inside, be provided with demarcation strip 3, described demarcation strip 3 is shaped as T-shaped, and anechoic room is divided into three air-breathing noise elimination cavities, and described air-breathing noise elimination cavity comprises the first air-breathing noise elimination cavity 5 of air-breathing noise elimination cavity 4, second and the 3rd air-breathing noise elimination cavity 6; The air-breathing noise elimination cavity 4 of described one-level communicates by air intake passage 1 with the air-breathing noise elimination cavity 5 of secondary, and the air-breathing noise elimination cavity 5 of secondary is communicated with by air intake passage 28 with three grades of air-breathing noise elimination cavities 6, and the diameter of air intake passage 1 and air intake passage 28 is 6mm.
Preferably, described air-breathing silencing cavity is the cavity consisting of working of plastics.
When entering the first air-breathing noise elimination cavity 4, refrigerant gas through being communicated with the air intake passage 1 of the first air-breathing noise elimination cavity 1 and the second air-breathing noise elimination cavity 4, enters the second air-breathing noise elimination cavity 5 again, after the second air-breathing noise elimination 5 chamber bufferings, again by being communicated with the air intake passage 28 of the second air-breathing noise elimination cavity 5 and the 3rd air-breathing noise elimination cavity 6, enter the 3rd air-breathing noise elimination cavity 6, finally enter compresser cylinder, by three grades of air-breathing noise elimination cavities, expand step by step decompression and reduced the pulsation of gas, thereby reduced suction noise.
