Description
Technical field
The utility model is related to a kind of air-breathing silencing cavity, especially a kind of air-breathing silencing cavity for compressor belongs to pressure
Contracting machine equipment technical field.
Background technology
In general, small-sized piston formula compressor is to receive power from motor, is compressed to refrigerant, to improve system
It is commonly used for refrigerator, refrigerating drinker, the household electrical appliance such as air-conditioning to the device of refrigerant pressure, and industrially also has
It is widely applied.
The overall noise of compressor institute application product is directly related to generally for the control of compressor noise, at present people
It is increasingly apparent to low noise, mute product requirement, while electric equipment products are also increasingly apparent to the small form factor requirements of compressor, it is traditional
Compressor noise-reducing structure is complicated, and overall volume is big, is unfavorable for noise control and compressor Miniaturization Design.
Utility model content
The goal of the invention of the utility model is：In view of the above problems, a kind of air-breathing for compressor is provided
Silencing cavity, good muffling effect, and it is simple in structure, it is conducive to compressor Miniaturization Design.
The technical solution adopted in the utility model is such：
A kind of air-breathing silencing cavity for compressor, including W types lower chamber and upper cavity, the upper cavity left and right ends point
It does not connect to form an inverted U cavity with W type lower chambers or so two upper ends, upper end passes through spacer body in the middle part of the W types lower chamber
Inner space is separated into level-one silencing cavity and two level silencing cavity with being connect in the middle part of upper cavity, level-one silencing cavity bottom opens up
Air entry and oil leaking hole, two level silencing cavity bottom open up oil leaking hole, and the spacer body includes horizontal connection level-one silencing cavity
With the second air intake passage of two level silencing cavity and vertical be connected to the of the second air intake passage and upper cavity top air-breathing silencers channel
Three air intake passages, air-breathing silencers channel side are equipped with gas outlet.
Above-mentioned technical proposal is simple and compact for structure, and compact contributes to compressor to minimize, while also having apparent
Noise reduction, manufacture difficulty is small, at low cost.
Preferably, inside the level-one silencing cavity a piece pipeline of setting be connected to the air entry of level-one silencing cavity bottom from
And the first air intake passage is formed, noise reduction can be further strengthened.

Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is described in detail.
Embodiment：
As shown in Figure 1, 2, a kind of air-breathing silencing cavity for compressor, including W types lower chamber 3 and upper cavity 1, it is described on
1 left and right ends of cavity connect to form an inverted U cavity with 3 or so two upper end of W types lower chamber respectively, in the W types lower chamber 3
Portion upper end is connect with 1 middle part of upper cavity by spacer body 2 inner space being separated into level-one silencing cavity 4 and two level silencing cavity 5, institute
It states 4 bottom of level-one silencing cavity and opens up air entry and oil leaking hole 3b, 5 bottom of two level silencing cavity opens up oil leaking hole 3b.Described point
Spacer 2 is as shown in Figure 3,4, including level is connected to the second air intake passage 2a of level-one silencing cavity 4 and two level silencing cavity 5 and vertically connects
The third air intake passage 2b of logical second air intake passage 2a and 1 top air-breathing silencers channel 1b of upper cavity, the air-breathing silencers channel
The sides 1b are equipped with gas outlet 1a.
A 4 inside piece pipeline of setting of the level-one silencing cavity is connected to be formed with the air entry of 4 bottom of level-one silencing cavity
First air intake passage 3a.
When refrigerant gas is by the first air intake passage 3a sucking level-one silencing cavities 4, air-breathing is reduced for the first time and is pulsed, then from
Second air intake passage 2a sucking two levels silencing cavity 5, pulsation is inhaled in second of reduction, finally from the 2b sucking compressions of third air intake passage
Machine, so as to reduce compressor air suction vibration and level of noise.
It is located at when motor plug 6 is installed immediately below 3 middle part of W types lower chamber, as shown in figure 5, can be conducive to rationally utilize
Compressor assembly space, to reduce compressor appearance and size.
