Description
Technical field
The utility model relates to sound arrester, particularly relates to a kind of sound arrester for smoke exhaust ventilator.
Background technology
Smoke exhaust ventilator, also known as range hood, is a kind of kitchen appliance purifying kitchen environment. It is arranged on above the health energy-saving range hood cooking stove of kitchen, can be taken away rapidly by the harmful oil smoke that produce in the refuse of cooking stove burning and cooking process, outside discharge chamber, and decreasing pollution, purification air, and have gas defence, explosion-proof safety control effect. Existing smoke exhaust ventilator produces negative pressure by the high speed rotating of wind wheel to realize smoke pumping work, so noise is very big during work, has the field of requirement not too practical noise at some. Meanwhile, above-mentioned noise brings bigger bothering, and carries out it suppressing significant. Traditional scheme of making an uproar of falling sets up passive noise elimination material or structure, such as the cotton that absorbs sound, reactive muffling device, Noise reduction tile etc. But for low frequency spectrum lines noise, not only volume, weight are big for aforesaid method, also can bring the pressure-losses, affect the performance of vent fan.
Practical novel content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of structure is simple, the sound arrester for smoke exhaust ventilator of excellent property.
For achieving the above object, the utility model is achieved through the following technical solutions:
For a sound arrester for smoke exhaust ventilator, comprising:
