Description
Technical field
The utility model is a kind of blower volute structure of range hood, belongs to the renovation technique of the used blower volute structure of range hood.
Background technique
Range hood has now become one of people kitchen imperative equipment, centrifugal fan is big because of its relative suction, noise ratio is lower, thus extensively adopted by range hood, still, though its noise is lower, in any case but still exist, its noise is generally from two aspects, the one, impeller noise, the 2nd, the turbulence noise that air-flow moves and sends in spiral case, existing denoising structure is based on the design that how to reduce the source of sound that has produced more.As disclosing " a kind of volute of blower of top sucking type kitchen ventilator " among the Chinese patent ZL01132056.7, its place at snail tongue place is improved, and reaches the purpose of improving noise, and the shortcoming of its existence is a complex structure, makes trouble, the cost height.
The model utility content
The purpose of this utility model is to consider the problems referred to above and blower volute structure that a kind of range hood is provided.The utility model is not only saved the space, cost is low, safe in utilization, easy to operate, long service life.
The technical solution of the utility model is: include housing, the upper end of housing is provided with intake grill, the lower end of housing is provided with the mounting hole that motor is installed, and the inboard of the intake grill of its middle shell upper end is equiped with flow skirt and/or is equiped with time flow skirt in the inboard of the mounting hole of housing lower end.
Above-mentioned housing comprise upper shell, lower shell body and be connected upper shell and lower shell body between the more intermediate annular housing.
The above-mentioned width of going up flow skirt is D1, and the distance of first end face of last flow skirt and impeller is d1, and the setting angle between last flow skirt and upper shell is φ 1, d1≤D1 wherein, and 5 degree≤φ 1≤90 spend.
The width of above-mentioned down flow skirt is D2, and the distance of second end face of following flow skirt and impeller is d2, and the setting angle between following flow skirt and the lower shell body is φ 2, d2≤D2 wherein, and 5 degree≤φ 2≤90 spend.
Above-mentioned upper shell and last flow skirt are by being welded to connect.
Above-mentioned lower shell body and following flow skirt are by being welded to connect.
The utility model owing to adopt is equiped with flow skirt and/or is equiped with the structure of flow skirt down in the inboard of the mounting hole of housing lower end in the inboard of the intake grill of housing upper end, thereby reduce the eddy current that produces between spiral case housing and the impeller, between impeller two ends and corresponding spiral case housing, form air-flow, make airflow smooth, and then reach the purpose that improves blast and reduce noise.The utility model is that a kind of design is ingenious, function admirable, the blower volute structure of convenient and practical range hood.
