Abstract
The utility model discloses a low-noise range hood. The low-noise range hood comprises a machine box with an air inlet and an air outlet, and a draught fan assembly, wherein the machine box is internally provided with a sound insulation set; top sound insulation blocks, wall face sound insulation blocks and a middle sound insulation block of the sound insulation set are arranged at the top in the machine box, on the peripheral inner wall face of the machine box, and between the draught fan assembly and the air inlet, respectively, so as to effectively reduce the strength of air-speed airflow in the machine box on the basis of promoting the great exhaust air rate and improving the air exhausting efficiency; the top of the middle sound insulation block with a triangular section is arranged towards the air inlet and a flow guide path is formed in the machine body, so that airflow entering from the air inlet sequentially flows out towards the air outlet, the collision of the airflow with the machine body is reduced, noise is further reduced and a comfortable utilization environment is improved.
Description
Technical field
The utility model relates to smoke exhaust ventilator field, relates in particular to a kind of low noise cooker hood
Background technology
At present, the smoke exhaust ventilator of using as purification kitchen environment, it generally adopts centrifugal fan group that the harmful oil smoke producing in the refuse of cooking stove burning and cooking process is taken away rapidly, outside discharge chamber, reduces and pollutes, and purifies the air of a room.In the time that oil smoke is larger, improve air suction efficiency, increase exhausting amount, the power that just must increase centrifugal fan group is realized, be formed in cabinet and produce stronger chaotic wind speed air-flow, in the chaotic wind speed air-flow that this is stronger and cabinet, surrounding wall, top and each parts produce larger collision, produce larger noise, affect the comfortableness that smoke exhaust ventilator uses, make troubles to consumer.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of at larger exhaust air rate, improve the noise that produces in effectively reducing use procedure under the basis of air suction efficiency, the low noise cooker hood of comfortable environment for use be provided.
To this, a kind of low noise cooker hood of the present utility model, includes cabinet and the fan assembly of air inlet, exhaust outlet, fan assembly is installed in cabinet, wherein, be provided with sound insulation group in described cabinet, sound insulation group is arranged at respectively on top, surrounding internal face and the middle part in cabinet.
Be optimized according to above-mentioned, described sound insulation group comprises top noise insulation block, wall noise insulation block and middle part noise insulation block, and described top noise insulation block, wall noise insulation block and middle part noise insulation block are arranged at respectively on top, surrounding internal face and the middle part in cabinet.
Be optimized according to above-mentioned, noise insulation block corresponding air inlet in described middle part is arranged on the middle part in cabinet and with air inlet and forms water conservancy diversion road warp.
Be optimized according to above-mentioned, described middle part noise insulation block is arranged in the cabinet between fan assembly and air inlet.
Be optimized according to above-mentioned, the cross sectional shape of described middle part noise insulation block is triangle, and the top of the middle part noise insulation block of section triangle is towards air inlet setting.
Be optimized according to above-mentioned, described top noise insulation block, wall noise insulation block and middle part noise insulation block are respectively Sound-proof material piece.
The beneficial effects of the utility model are: by be provided with sound insulation group in cabinet, the top noise insulation block of this sound insulation group, wall noise insulation block and middle part noise insulation block, described top noise insulation block, wall noise insulation block and middle part noise insulation block are arranged at respectively the top in cabinet, on between surrounding internal face and fan assembly and air inlet, make stronger wind speed airflow collision in sound insulation group, impel at larger exhaust air rate, improve under the basis of air suction efficiency, effectively be reduced in the intensity of the wind speed air-flow in cabinet, and the top of the middle part noise insulation block of section triangle is towards air inlet setting, make formation water conservancy diversion road warp in cabinet, the air-flow entering from air inlet is flowed out to exhaust outlet in an orderly manner, reduce with cabinet and bump, further reduce noise.
Brief description of the drawings
Fig. 1 is the stereogram of the utility model preferred embodiment.
Fig. 2 is the cutaway view of the utility model preferred embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 to Fig. 2 illustrates the preferred embodiment of the utility model, and it has cabinet 1 and the fan assembly 2 of air inlet 11, exhaust outlet 12, and fan assembly 2 is installed in cabinet 1.In described cabinet 1, be provided with sound insulation group, sound insulation group is arranged at respectively on top, surrounding internal face and the middle part in cabinet 1.Wherein, described sound insulation group comprises top noise insulation block 3, wall noise insulation block 4 and middle part noise insulation block 5, described top noise insulation block 3, wall noise insulation block 4 and middle part noise insulation block 5 are arranged at respectively on top, surrounding internal face and the middle part in cabinet 1, and top noise insulation block 3, wall noise insulation block 4 and middle part noise insulation block 5 are respectively Sound-proof material piece, in practical application, this sound insulation plate can be fire-proof sound insulation foam, impel at larger exhaust air rate, improve under the basis of air suction efficiency, effectively be reduced in the intensity of the wind speed air-flow in cabinet 1, reduce the noise of the smoke exhaust ventilator in using.Moreover, described middle part noise insulation block 5 is arranged in the cabinet 1 between fan assembly 2 and air inlet 11, and, the cross sectional shape of this middle part noise insulation block 5 is triangle, and the top of the middle part noise insulation block 5 of section triangle arranges towards air inlet 11, make the corresponding air inlet 11 of middle part noise insulation block 5 of section triangle be arranged at upper between fan assembly 2 and air inlet 11 and form water conservancy diversion road 6 with air inlet 11, the air-flow entering from air inlet 11 is flowed out to exhaust outlet 12 in an orderly manner, reduce with cabinet 1 and bump, further reduce noise.
Above-mentioned specific embodiment is only the good detailed description of the invention of the utility model effect, and all or low noise cooker hoods of being equal to identical with this structure, all in the application's protection domain.
