Abstract
The utility model provides a through-flow air duct system, which comprises an air guide volute, a tongue, a through-flow wind wheel, an evaporator and air inlet gratings at the periphery; and the system is characterized in that: the tongue has a stepped shape; a stepped surface of the stepped shape faces a side lower part of a protruding convex part of the through-flow wind wheel. Due to the adoption of the stepped tongue, the characteristics of high air quantity when a gap between the tongue and the through-flow wind wheel is small and low noise when the gap between the tongue and the through-flow wind wheel is large can be realized, and effects of improving the air quantity and reducing the noise in the whole through-flow air duct system are achieved.
Description
Technical field
The utility model relates to refrigerating field, relates in particular to a kind of through-flow ducting system, belongs to the improvement technology of air-conditioning through-flow ducting system.
Background technology
In air-conditioner, the snail tongue of through-flow ducting system and the gap of tubular wine wheel are very big to the influence of blower fan system aerodynamic characteristic, referring to Fig. 1 and Fig. 2; Fan pressure head pressure reduces when its gap is big, and air quantity reduces, and pressure raises when its gap is less; Air quantity increases, but the also corresponding increase of noise simultaneously.This mainly is can control whole pneumatic mobile eccentric vortex because there is one in the cross flow fan interior flow field, and it makes the air-flow of having discharged refund again and flow to impeller inside that when reaching quasi-stationary state when flowing, eccentric vortex is near the tongue position, whirlpool of blower fan.When whirlpool tongue and tubular wine wheel gap were big, blower fan internal reflux zone was big, makes the main flow area flow reduce; When whirlpool tongue and tubular wine wheel gap hour, blower fan internal reflux zone is little, the main flow area flow increases, fan pressure head pressure raises simultaneously.Above-mentioned whirlpool tongue and tubular wine wheel gap through-flow ducting system or whirlpool tongue hour be the through-flow ducting system when big with the tubular wine wheel gap, all can not solve the problem that promotes air quantity and reduction noise simultaneously.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of prior art; A kind of through-flow ducting system is provided; Can realize possessing simultaneously whirlpool tongue and tubular wine wheel gap big air quantity hour and whirlpool tongue with the tubular wine wheel gap the low noise characteristics greatly the time, reach whole through-flow ducting system and promote air quantity and reduction anti noise simultaneously.
The purpose of the utility model realizes through following technical proposals: a kind of through-flow ducting system; Comprise wind-guiding spiral case, snail tongue, tubular wine wheel, evaporimeter and air-inlet grille; Said air-inlet grille is arranged on the inlet side of tubular wine wheel, and evaporimeter is characterized in that between tubular wine wheel and air-inlet grille; Described snail tongue is stepped ramp type, and the step surface of said stepped ramp type is towards its side-lower of the male portion of tubular wine wheel projection.
The cross section of the stepped ramp type in above-mentioned snail tongue stage casing comprises at least one step, and during said step comprises following three sections, said three sections is arc shaped or strip, and changes from small to big in three sections gaps with tubular wine wheel of step.
The epimere of above-mentioned snail tongue stepped ramp type step and the hypomere of step are 2～10mm in 10mm distance with interior drop on the tubular wine wheel direction.
Above-mentioned snail tongue and the air-conditioning water container structure that is formed in one perhaps is fixed on the integrated chassis.
The utility model is with respect to prior art; Has following beneficial effect: adopt stepped ramp type snail tongue structure; Make it possess big air quantity of little gap snail tongue through-flow ducting system and the low noise characteristics of big gap snail tongue through-flow way system simultaneously, reach whole through-flow ducting system and promote air quantity simultaneously and reduce anti noise.

Particularly, the cross section of the stepped ramp type in described snail tongue 2 stage casings comprises at least one step, and during said step comprises following three section 21,22,23, said three sections is arc shaped or strip, and three section 21,22 of step, and 23 change from small to big with the gap w of tubular wine wheel 3.
Further, the hypomere 23 of the epimere 21 of described snail tongue 2 stepped ramp type steps and step is 2 ~ 10mm in the 10mm distance with interior drop X on tubular wine wheel 3 directions.
In the present embodiment, described snail tongue 2 and the air-conditioning water container structure that is formed in one perhaps is fixed on the integrated chassis.
As shown in Figure 3 is through-flow ducting system sketch map among the utility model embodiment, and wherein the pivot of tubular wine wheel 3 is benchmark of whole indoor set.The through-flow ducting system comprises wind-guiding spiral case 1, snail tongue 2, tubular wine wheel 3, evaporimeter 4 and peripheral air-inlet grille 5, through the rotation of tubular wine wheel 3, air-flow is got into from air-inlet grille 5, passes evaporimeter 4 and tubular wine wheel 3 successively, is seen off from air outlet at last.
The foregoing description is merely the preferred embodiment of the utility model, is not the practical range that is used for limiting the utility model.Be that all equalizations of being done according to the utility model content change and modification, all contained by the utility model claim scope required for protection.
