Few obstruction to air-flow, it is to avoid influence ventilation, so as to reduce partial noise.Noise reduction ring 020 can be carried out to the air-flow in circle portion 931
Rectification, so as to reduce the noise that the noise source near round portion 931 is sent.And acoustical panel 011 and the equal elastic connection of bloop 022,
The effect transmitted with slowing down vibration, so as to reduce the noise of itself generation.
Embodiment two
A kind of Jing Yin range hood is present embodiments provided, this Jing Yin range hood includes range hood body and Jing Yin
Spiral case 001.
Jing Yin spiral case 001 is arranged in range hood body, and fume-exhausting is improved by the reduction of the Jing Yin noise of spiral case 001
The overall noise content of machine.
In the Jing Yin spiral case 001 that the present invention is provided, the setting of the first bloop 150 and the second bloop 250 can protected
Rectification is carried out on the basis of card air quantity to gas so as to noise reduction, and damping silencer plate 010 sets at inlet air passage 913 and can subtracted
Few obstruction to air-flow, it is to avoid influence ventilation, so as to reduce partial noise.Noise reduction ring 020 can be carried out to the air-flow in circle portion 931
Rectification, so as to reduce the noise that the noise source near round portion 931 is sent.And acoustical panel 011 and the equal elastic connection of bloop 022,
The effect transmitted with slowing down vibration, so as to reduce the noise of itself generation.
By the way that the noise reduction ring 020 that provides of the present invention is installed in range hood, distinguished and admirable generation at spiral case can be shaken
It is dynamic to be eliminated by bloop 022, and bloop 022 can produce vibration because distinguished and admirable, pass through noise reduction ring clip 021 and bloop
Elastic component between 022 can lower the vibration transmission between bloop 022 and noise reduction ring clip 021.
The preferred embodiment of the present invention is the foregoing is only, is not intended to limit the invention, for this area
For technical staff, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made is any
Modification, equivalent substitution, improvement etc., should be included in the scope of the protection.
