Detailed description of the invention
This detailed description of the invention provides a kind of snail tongue device, and it effectively can reduce wind noise, and can reduce air-flow circulating in spiral case.This detailed description of the invention additionally provides a kind of air-conditioner comprising above-mentioned snail tongue device.
Please refer to Fig. 2-Fig. 6, the snail tongue device that this detailed description of the invention provides, comprise installing plate 11 and multiple snail hyoid tooth 12, wherein, multiple snail hyoid tooth 12 is evenly arranged on installing plate 11, have certain distance between arbitrary two snail hyoid tooths 12, to form air-guiding aisle, the air-guiding aisle of air-flow between snail hyoid tooth 12 of cross flow fan blowout is derived.
Region between cross flow fan and snail tongue device is due to cross flow fan properties influence, an eccentric vortex recirculation zone can be formed, snail hyoid tooth gap location wind speed is also higher, and the size in this snail hyoid tooth gap, region and the structure of snail hyoid tooth will directly affect air-out uniformity and the noiseproof feature of cross flow fan.
In this detailed description of the invention, along the direction, 13 to rear end, front end 14 of snail hyoid tooth 12, namely along the primary air direction of cross flow fan, reduce gradually after the width of snail hyoid tooth 12 is increased to Breadth Maximum W gradually, and the distance of the position of front end 13 to Breadth Maximum W is less than the distance of position to the rear end 14 of Breadth Maximum W; And the surface of snail hyoid tooth 12 is streamline curved surface.
Setting like this, the snail tongue device that this detailed description of the invention provides, when the structure of snail hyoid tooth 12 makes air-flow be separated with snail hyoid tooth 12, whole flow boundary layer air is made to be close to the surface of snail hyoid tooth 12, when air-flow occurs to be separated simultaneously, decrease the blending with surrounding fluid, avoid larger momentum and energy hunting, reduce noise improvement tonequality, also reduce circulating of air-flow in spiral case.
In the preferred version of this detailed description of the invention, the distance of front end 13 to the position of its Breadth Maximum W of snail hyoid tooth 12, is less than or equal to 1/3rd of the distance of position to the rear end 14 of its Breadth Maximum W.Such as, the distance of front end 13 to the position of its Breadth Maximum W of snail hyoid tooth 12, equals 1/3rd of the distance of position to the rear end 14 of its Breadth Maximum W, so arranges, and the snail tongue in equal gap in contrast prior art, noise can reduce by 0.8 ~ 1.2 decibel.
In addition, it should be noted that, the intensity of appearance and size to territory, spiral inlet area noise of snail hyoid tooth 12 also has material impact.And the dimensional parameters of snail hyoid tooth 12 can affect the intensity of snail hyoid tooth 12.In this detailed description of the invention, preferably the width of the position of the Breadth Maximum W of snail hyoid tooth 12 is set to 2-3mm, the length L of snail hyoid tooth 12 is set to 28-30mm, and height H is set to 11-13mm.Setting like this, ensure that snail hyoid tooth 12 has outside good intensity, its dimension scale is suitable, reduce further the noise intensity in territory, spiral inlet area.
In addition, in order to avoid the problem of airflow reflux, in this detailed description of the invention, by two of arbitrary neighborhood snail hyoid tooths 12, the distance between the position of the two Breadth Maximum W is set to 2-3mm, and the distance between the two end is 4-6mm.Setting like this, on the steady and uniform basis that ensure that air-out air-flow, can the generation of effectively anti-backflow.
In addition, in this detailed description of the invention, the head 15 of snail hyoid tooth 12 can be provided with rounding structure, and the radius of rounding structure is preferably 4-5mm.Setting like this, head 15 streamline of snail hyoid tooth 12 is better, reduce further the generation of stream swirl.
This detailed description of the invention additionally provides a kind of air-conditioner comprising above-mentioned snail tongue device, so arrange, the air-conditioner that this detailed description of the invention provides, effectively can reduce pneumatic noise, and the circulating current in its spiral case effectively can be reduced.The derivation of the beneficial effect that the derivation of this beneficial effect and above-mentioned snail tongue device bring is substantially similar, therefore repeats no more herein.
