Abstract
The utility model relates to a centrifugal leaf blade air guide ring. The utility model is mainly characterized in that soft layers are respectively and additionally arranged on the inner wall and the outer wall of a ring body, the soft layers can be polyethylene-polyurethane composite spongy layers, and the thickness of the soft layers preferably ranges from 6 mm to 8 mm. The utility model has the advantages of simple structure and favorable effect in lowering noise.
Description
The utility model relates to a kind of centrifugal fan air-ducting ring that is used for air conditioner.
Existing air conditioner centrifugal fan air-ducting ring is made by steel plate merely.Air communication is crossed air-ducting ring during air conditioner work, can make the air-ducting ring vibration, produces big noise, influences surrounding environment.
The purpose of this utility model provides a kind of air conditioner when work of reducing, and air communication is crossed the vibration that air-ducting ring produces, and reduces the low noise centrifugal fan air-ducting ring of air conditioner total noise of centrifuge.
The technical solution adopted in the utility model is: the inside and outside wall of circle body 1 set up respectively flexible layer 2,2 '.Said gentle layer 2,2 ' can be the compound sponge layer of polyethylene one polyurethane.The thickness of the compound sponge layer of said polyethylene-polyurethane is good with 6-8mm.
The utility model is simple in structure, and when air-flow passed the utility model, the flexible layer of circle body outer wall can prevent that air-ducting ring from producing resonance, and can absorb and weaken the pneumatic noise that is produced by air swirl, so the noise reduction sound is effective.
Accompanying drawing 1 is the utility model structural representation.
Referring to accompanying drawing 1, circle body 1 can be made of sheet metal, and the outer wall of circle body 1 is pasted with flexible layer 2, the inwall of circle body 1 be pasted with flexible layer 2 '.Flexible layer 2,2 ' be polyethylene-polyurethane sponge layer.This flexible layer also can be made of traditional sound-absorbing porous material.The thickness of polyethylene-polyurethane sponge layer is good with 6-8mm.
Claims (3)
1, a kind of low noise centrifugal fan air-ducting ring, the inside and outside wall that it is characterized by circle body (1) is respectively equipped with flexible layer (2), (2 ').
2,, it is characterized by said flexible layer (2), (2 ') are the compound sponge layer of polyethylene one polyurethane by the described a kind of low noise centrifugal fan air-ducting ring of claim 1.
3, by this low noise centrifugal fan air-ducting ring of claim 1,2, the thickness that it is characterized by the compound sponge layer of polyethylene one polyurethane is 6-8mm.
