Abstract
The utility model relates to a range hood fan structure, including the spiral case on set up air intake and air outlet the air outlet on be provided with the air outlet subassembly on be provided with the spiral tongue. The utility model aims at overcoming the defects of the prior art and providing a fan structure of a range hood with simple structure, small volume and high efficiency.
Description
[technical field]
The utility model relates to a kind of cooking-fume exhauster blower structure.
[background technique]
Now forward multiple wing leaf centrifugal blower is because efficient is higher relatively, and cost is low and extensively applied among the household electric appliance.When its structural design, all select snail tongue and spiral case integrated formed structure for use in the industry at present, technology is comparatively complicated, and blower fan overall structure size is bigger, and the fan noise quality also is difficult to control.
The utility model is exactly to make in view of the situation.
[model utility content]
The utility model has overcome the deficiencies in the prior art, and a kind of simple in structure, volume is little, efficient is high cooking-fume exhauster blower structure is provided.
The utility model is for solving the problems of the technologies described above, by the following technical solutions:
A kind of cooking-fume exhauster blower structure is characterized in that including spiral case, at described spiral case intake grill and exhaust outlet is set, and described exhaust outlet is provided with the exhaust outlet assembly, and described exhaust outlet assembly is provided with the snail tongue.
Aforesaid a kind of cooking-fume exhauster blower structure is characterized in that on described exhaust outlet assembly, is provided with angle of flare with snail tongue opposite external side.
Aforesaid a kind of cooking-fume exhauster blower structure, the angle value added that it is characterized in that described angle of flare are 6 ° ~ 12 °.
Aforesaid a kind of cooking-fume exhauster blower structure is characterized in that described snail tongue is V-type snail tongue, and the snail tongue is provided with the locating slot that can be fixed on the exhaust outlet assembly.
Aforesaid a kind of cooking-fume exhauster blower structure is characterized in that described exhaust outlet is provided with and exhaust outlet assembly flange connecting, and described exhaust outlet assembly is connected by screw with flange.
The utility model compared with prior art has following advantage:
The utility model is simple in structure, adopt volute casing and the split type structure of snail tongue, diffuser pipe in the original structure is moved on the exhaust outlet holder assembly, have additional angle of flare at the exhaust outlet assembly, this structure is easy for installation, need not former draught fan impeller structure made amendment and just can effectively improve the bigger problem of blower sizes, blower fan aeroperformance and noise quality are also effectively improved thereupon.
