Abstract
The utility model provides a smoke exhaust ventilator which is used to discharge oil with low noise in kitchens. The smoke exhaust ventilator adopts an inner shell structure which is shaped by a micro perforated panel, a fan installation cavity structure which is provided with a transverse micro perforated panel and a vertical micro perforated panel, an inner layer air exhaust pipe knee structure which is shaped by the micro perforated panel and a sound-absorbing layer structure which is attached on the outer surface of a fan shell and is made of sound-absorbing materials, a sound-deadening resonant cavity structure which is composed of each micro perforated panel and a corresponding outer shell structure and a resistance noise reduction structure which is formed by the sound-absorbing layer, wherein low, medium and high noise in the whole frequency band which is generated in the working process of the smoke exhaust ventilator can obtain good sound-deadening effect, thereby solving the noise problem which is generated when the smoke exhaust ventilator is used.
Description
Technical field
The utility model relates to kitchen utensils, is a kind of low noise smoke exhaust specifically.
Background technology
The family expenses smoke exhaust is used for the kitchen can get rid of the flue gas that produces when cooking, keep cleaning and health in the kitchen, become the requisite cooking apparatus of Modern Family. but be the very noisy that produces by blower fan with the problem that the use of smoke exhaust brings, long-term housewife and the kitchen operation personnel that under this noise, work, can produce headache, bad reflection such as irritated, nervous, healthy causing seriously influenced.
The utility model content
The purpose of this utility model is do not changing under air quantity, the blast prerequisite at the noise problem of existing family expenses smoke exhaust generation, and a kind of low noise smoke exhaust is provided.
The technical scheme that realizes above-mentioned purpose is: a kind of low noise smoke exhaust, and blower fan that the cavity that include shell body, inner housing, places inside and outside housing to constitute is interior and the air draft elbow that joins with the blower fan exhaust outlet, its inner housing adopts microperforated panel moulding.
The technical solution of the utility model also comprises: be provided with horizontal and vertical microperforated panel in the blower fan installation cavity that its shell body of front position of smoke exhaust and microperforated panel inner housing constitute; The air draft elbow that itself and blower fan exhaust outlet join is by outer bend pipe and place the microperforated panel internal layer bend pipe in the outer bend pipe to constitute.
Housing outer surface at blower fan is installed with sound absorbing layer, is another technical characterictic of the present utility model.
The utility model is by being arranged to the microperforated panel structure with the inner casing of smoke exhaust, horizontal, vertical microperforated panel is installed in the blower fan installation cavity, in the air draft elbow, add the internal layer bend pipe of microperforated panel structure, just each microperforated panel constitutes the resonant cavity sound absorption structure with corresponding shell, and effectively removes the noise that produces when smoke exhaust is worked.
It makes itself and shell form two resonant cavities at the strongest two-layer noise elimination microperforated panel of front inner housing location arrangements of noise reflection, can reach more desirable noise elimination effect.
And adhere to the sound absorbing layer that constitutes by sound-absorbing material at the outer surface of outer cover of blower fan, make noise damped absorption in deadener, form resonance and resistive compound noise elimination with the microperforated panel noise elimination structure, and the noise in the basic, normal, high whole frequency obtained good noise elimination effect.
Description of drawings
Fig. 1 is this low noise lampblack exhauster structure front view;
Fig. 2 is that cutaway view is looked on the left side of Fig. 1.
The specific embodiment
Embodiment describes the specific embodiment of the present utility model in conjunction with the accompanying drawings:
Provide as accompanying drawing, this low noise smoke exhaust has the shell body 1 that constitutes the smoke exhaust external form, and the shell body phase configuration is provided with the inner housing 2. that adopts the microperforated panel moulding and is provided with internal layer microperforated panel 11. at the medium position of the cavity of the lampblack absorber that is surrounded by shell body and inner housing blower fan 3 is installed between its shell body 1 of the front of smoke exhaust and inner housing 2, and the outer surface of the housing 5 of its blower fan has been installed with sound absorbing layer 6.Be respectively arranged with horizontal and vertical microperforated panel 4 in the cavity of the both sides of blower fan, this is laterally, vertical microperforated panel sets individual layer or bilayer according to designing requirement. and on shell body 1, connect and be equipped with by microperforated panel internal layer bend pipe 9 and outer bend pipe 8 and be inlaid in the air draft elbow 7. that the air door 10 of internal layer bend pipe lower end is formed with the blower fan exhaust outlet
The thickness of slab of microperforated panel of the present utility model can be selected 0.5～1mm, aperture 0.5～1mm, and punching rate: internal layer selects 1%～2%, skin 2%～3%, cavity depth 50～200mm.The sound-absorbing material that is arranged at the Blower Housing surface can be selected flame retardant type, nontoxic rubber and plastic foam class material.
When the utility model is specifically implemented, can be used to reduce the noise that produces because of vibration adding Rubber shock-absorbing pad such as the fixedly connected pin of blower fan, blower fan exhaust outlet and air draft elbow and shell connecting interface and air inlet protective cover and blower fan assembling interface.
