Abstract
The present invention relates to a cooker hood for kitchens. The present invention is composed of a machine casing, a micromotor, a blower, an oil collecting cup, a lighting device, a switch, an air intake, an air exhaust port, wherein the front disc of an impeller of the blower is coned, and the outside diameter of the impeller is 215mm<=D-[1]<=283mm; the arc radius of an impeller blade is 160mm<=R-[4]<=215mm; the diameter of the arc center of the impeller blade is 196mm<=D-[3]<=380mm; the inlet diameter of the front disc of the impeller is 155mm<=D-[2]<=210mm; the tilting angle of the cone of front disc of the impeller is 0.5 DEG <= alpha <=32 DEG. The present invention is mainly used for kitchens of residential houses, especially suitable for being matched with kitchens of multi-storey houses and common exhaust pipeline systems; the present invention can be used as a matched model selecting product when the building design of a dwelling house is caried out.
Description
The present invention relates to a kind of smoke exhaust for kitchen use.It is applicable to that old kitchen and newly-built house kitchen cooperate operation as architectural design type selecting product with shared discharge duct, to get rid of the pernicious gas in the kitchen.
The present oil-containing air exhauster for kitchen that generally uses, the design of its movement internal structure impeller and volute of blower makes the loss of machine self-energy bigger, and the blast that smoke exhaust provided is low excessively, and fan characteristic and shared exhaust pipe system resistance are not complementary when moving.When the common exhaust duct SR increased, the smoke exhaust running status worsened, and exhaust air rate significantly reduces, to the eliminating effect reduction that makes kitchen internal contamination thing.Simultaneously, the air exit blast that smoke exhaust provided that is installed on the common exhaust duct is excessive, easily produces each layer of multi-storey building building kitchen again by collaborate the mutually problem of (promptly scurrying flavor) of common exhaust duct.Therefore, the suitable outlet overbottom pressure that smoke exhaust provided is very crucial.In addition, adopt directly drains into the atmosphere mode with exhaust outlet by wall and exterior window more when smoke exhaust is used for old kitchen, when outdoor face velocity is big, can makes operating smoke exhaust exhaust air rate reduce, and influence filth-discharging effect.Existing smoke exhaust can't address the above problem owing to its structural reason.
The purpose of this invention is to provide a kind of smoke exhaust when extraneous change in resistance, smoke exhaust still can be stablized and operation reliably, when matching operation with multi-storey residential buildings common exhaust duct system, can avoid scurrying mutually between each layer kitchen flavor again, and can reduce oil-fume extractor motor power consumption, reduce the operation noise.
The objective of the invention is to be achieved through the following technical solutions.The impeller shroud is designed to taper, and each spot size of impeller blade is optimized design, determine optimized data.The spiral case inwall of smoke exhaust adopts accurate spiral of Archimedes type.In addition, the side plate and the housing top panel of blower fan is designed to a plate, so both can saves raw material, can fall few vibrations again.
The present invention has been owing to adopted the said structure scheme, thereby has depollution thing efficient height compared with similar products, and power consumption is few, and noise is little, and running status is good, and it is good and cooperate the advantage that can prevent gas blowby when moving with shared exhaust duct that resistive drag force changes interference.
Now the invention will be further described in conjunction with the accompanying drawings.
Fig. 1 is the main pseudosection of smoke exhaust;
Fig. 2 is the vertical view of smoke exhaust;
Fig. 3 is an impeller master pseudosection in the smoke exhaust;
Fig. 4 is an impeller vertical view in the smoke exhaust;
Fig. 5 is an impeller shroud front view in the smoke exhaust;
Fig. 6 is installed in the interior schematic diagram of house kitchen of common exhaust duct system for smoke exhaust of the present invention.
The interior employing of house kitchen that Fig. 7 is installed in no common exhaust duct system for smoke exhaust of the present invention directly effluxes the schematic diagram of mode.
At smoke exhaust 1 of the present invention, lighting device 9, micromachine 17, switch 18 are installed on the housing 2 of smoke exhaust, and micromachine 17 drives a blower fan, by air inlet 3 oil smoke in the kitchen and dusty gas are sucked in the spiral case 7 of smoke exhaust 1.Automatically isolate sump oil then and be collected in the catchment cup 5 and discharge, the gas after sump oil separates drains into common exhaust duct 14 by exhaust outlet 4, and the pipe outlet of being located at roof layer roofing through common exhaust duct drains into atmospheric dilution again.Perhaps in old kitchen, adopt the mode that directly effluxes that gas directly is discharged into atmosphere by exterior window or exterior wall.Draught fan impeller is by shroud 10, hub disk 11, and blade 12, hub 13 is formed, and in order to finish the task that the present invention proposes, by experiment impeller each several part size is optimized design, and obtains optimization numerical value.The overall diameter D of impeller
1Be 215mm≤D
1≤ 283mm; Impeller blade arc radius R
4Be 160mm≤R
4≤ 215mm; The place diameter D of impeller blade center of arc
3Be 196mm≤D
3≤ 280mm; Impeller shroud inlet diameter D
2Be 155mm≤D
2≤ 210mm; And the impeller shroud is designed to taper, and the tilt angle alpha of its taper is 0.5 °≤α≤32 °, and in addition, the inwall of spiral case 7 is designed to accurate spiral of Archimedes type.For conservation with reduce vibrations, with the side plate 8 of blower fan and the shared plate of top panel of casing 2.Each positional parameter optimum value of impeller is respectively D
1=274mm, D
2=170mm, D
3=260mm, R
4=202mm, α=21 °.
