Description
Technical field
Filed of air conditioning is the utility model is related to, in particular to a kind of silencer cover and air conditioner.
Background technology
When air conditioner is run, the radiated noise of compressor and pipe arrangement enters human ear by air borne, causes air conditioner chamber
Outer machine level of noise rise, air-conditioner outdoor unit noise sound quality deterioration, and the high noisy value of air-conditioner outdoor unit and difference tone matter can drop
Low user experience, so as to cause the complaint of user and complaint.
Therefore, how to propose that one kind can reduce noise, improving the air conditioner of tonequality turns into current urgent problem to be solved.
Utility model content
The utility model is intended at least solve one of technical problem present in prior art or correlation technique.
Therefore, a purpose of the present utility model is the provision of a kind of silencer cover.
Another purpose of the present utility model is the provision of a kind of air conditioner for including above-mentioned silencer cover.
To achieve the above object, the embodiment of the utility model first aspect provides a kind of silencer cover, for air conditioner
Compressor assembly, the compressor assembly includes compressor and pipe arrangement, and the silencer cover includes:Cover body, institute can be located at
State on compressor assembly;Dowel, it is arranged on the internal face of the cover body;Inner plating, in the cover body, the company
Connect on muscle, and at least one closing chamber is formed with the dowel and the cover body, be provided with the inner plating at least one
Through hole, the through hole connect with the closing chamber, and the bore of the through hole is less than or equal to 1mm more than or equal to 0.2mm;Wherein, institute
Noise caused by compressor assembly is stated into after the silencer cover, the air column in the through hole can be made in the closing chamber
Vibrated repeatedly under the elastic reaction of air.
The silencer cover that the embodiment of the utility model first aspect provides, including the cover being located on compressor and pipe arrangement
Body, and the inner plating being arranged in cover body, and multiple through holes are provided with inner plating, this kind of structure, inner plating can and cover
The internal face and dowel of body form multiple closing chambers, and through hole can turn on closing chamber, therefore, logical by rationally setting
The distance between the size and inner plating in hole and cover body inwall, can form one or more helmholtz resonances in the cover body
Chamber, so as to it can be seen from Helmholtz's noise-cancelling theory, when the cover body is located on the compressor and pipe arrangement of air conditioner, compress
Noise just can be entered in the resonant cavity in silencer cover caused by machine and pipe arrangement, so as to just cause the air column in through hole
Vibration, and then the air column in through hole can be made to produce compression or dilatancy, and then a large amount of acoustic wave energies that can dissipate.Cause
This, the silencer cover is set by the compressor and pipe arrangement outer cover in air conditioner, just most of medium-high frequency noises can be utilized into last of the twelve Earthly Branches nurse
Huo Zi sound absorption principles are sponged, and then can prevent these medium-high frequency noises from entering human ear by air borne, thus can subtract
The noise during compressor operating of few air conditioner, improves the tonequality during compressor operating of air conditioner, body is used to improve user

In those embodiments, the hollow ellipse post of the preferably one end open one end closing of cover body 12, such one side energy
Compressor assembly enough is covered using silencer cover 1, on the other hand because the entirety of compressor assembly composition is also substantially oblong-shaped, because
This, ovalisation is set by cover body 12, additionally it is possible to and the overall structure for forming silencer cover 1 and compressor assembly is mutually adapted,
And then the structure of air conditioner can be made more rationally compact.
Certainly, cover body 12 or one end open and hollow other cylinders, such as square cylinder, circular cylinder etc..
Wherein it is preferred to the major axis of elliptic cylindrical length and elliptic cylindrical short axle length ratio be more than etc.
It is less than or equal to 1.6 in 1.2.
In those embodiments, the ratio between the major axis for the elliptical shape that compressor and pipe arrangement are formed and short axle substantially 1.5,
Therefore by being disposed greater than the length ratio of the length of the major axis of elliptic cylindrical and the short axle of elliptic cylindrical to be equal to 1.2
In the range of 1.6, can make the size of silencer cover 1 and overall structure size that compressor and pipe arrangement are formed substantially
It is mutually adapted, and then the structure of air conditioner can be made more rationally compact.
Wherein it is preferred to the major axis of elliptic cylindrical length and elliptic cylindrical short axle length ratio be 1.4,
That is the length ratio of the short axle of the length of the major axis of elliptic cylindrical and elliptic cylindrical is preferably 7:5.
In any of the above-described embodiment, it is preferable that the height of cover body 12 is more than the height of compressor and pipe arrangement, cover body 12
Width is more than the width of compressor and pipe arrangement, and the length of cover body 12 is more than the length of compressor and pipe arrangement.
In those embodiments, can form the ratio compressor of the length and width high setting of silencer cover 1 and pipe arrangement is overall long
It is wide high slightly bigger, so more easily the cover of cover body 12 can be set on compressor and pipe arrangement, while also can be more
Easily disassemble silencer cover 1, it is thus possible to improve the dismounting convenience of silencer cover 1.
Further, it is preferable that the height of cover body 12 is bigger 40%-50% than the height of compressor and pipe arrangement, the width of cover body 12
