The utility model provides a kind of through-flow ducting assembly, see Fig. 1 and Fig. 2, in one embodiment, this through-flow ducting assembly bag combines and forms the first spiral case 100 and the second spiral case 200 air-flow being played to the air channel 500 of guiding function, such as the first spiral case 100 and the second spiral case 200 are working of plastics, between the two by screw, buckle or both be fixed together.Support the use with this through-flow ducting assembly and can form the such as air conditioning such as vertical air-conditioner indoor unit, air purifier product, can produce by means of this through-flow ducting assembly the air-flow flowing through heat exchanger, purifier fast, and the air-flow through alternating temperature, filtration is sent.
In the present embodiment, through-flow ducting assembly also comprises tubular wine wheel 400 and is installed on above or below this tubular wine wheel 400 in order to control the motor 300 that tubular wine wheel 400 rotates, as shown in Figure 1, motor 300 is installed on the top of tubular wine wheel 400, and tubular wine wheel 400 is vertically placed.In order to reduce the noise of air-flow by producing during air channel 500, the inner surface limiting air channel 500 in first spiral case 100 and/or the second spiral case 200 is provided with at least one inwardly outstanding air guide structure (corresponding be respectively the first air guide structure 110 and the second air guide structure 210 see Fig. 3 and Fig. 4), air guide structure vertically extends on the whole, preferably, the two ends of air guide structure extend to the top and bottom in air channel 500 respectively.
Under the driving of tubular wine wheel 400, air-flow enters air channel 500 with certain deflection angle, therefore there is the region that some air-flows can not arrive in the wall in air channel 500, and the region that these air-flows can not arrive and periphery often produce eddy current and turbulent flow, thus cause the phenomenon that air-out is unstable, noise is large.By being provided with the air guide structure extended along vertical direction in air channel 500, to adjust the direction in airflow passes air channel 500, prevent air-flow generation in air channel 500 from easily causing eddy current and the turbulent flow of air-out shakiness, different sound, thus reduce wind noise, improve air-out tonequality, reach the effect improving user's comfort.
Composition graphs 2 ~ Fig. 6, in a specific embodiment, the inner surface of the first spiral case 100 and the second spiral case 200 is respectively arranged with an air guide structure, the first air guide structure 110 and the second air guide structure 210 respectively, first air guide structure 110 and the second air guide structure 210 on the air-out direction in air channel 500 with give set a distance spaced apart, as shown in Figure 2, air-out direction along air channel 500 arranges the first air guide structure 110 and the second air guide structure 210 successively, first air guide structure 110 and the second air guide structure 210 can change the direction of air-flow, thus the eddy current eliminated in air channel 500 and turbulent flow.Preferably, the cross section of the first air guide structure 110 is triangle, trapezoidal or circular arc, the cross section of first air guide structure 110 of such as the present embodiment is isosceles trapezoid, can from the lateral concave of the first spiral case 100, and the first air guide structure 110 forming integration is given prominence in the inner side of the first spiral case 100, structure is simple and easy to realize, and reduces windage, can not impact air output under the prerequisite of phenomenon eliminating air-out shakiness and different sound in air channel 500.
When tubular wine wheel 400 as shown in Figure 2 normally runs, tubular wine wheel 400 is rotated counterclockwise, part air quantity thus near the first spiral case 100 in air channel 500 is relatively large, and it is relatively little near the part air quantity of the second spiral case 200, therefore the blast of both sides, air channel 500 differs greatly, easily cause the phenomenon of air-out shakiness, and by the second air guide structure 210 is designed to tabular, and the second air guide structure 210 tilts towards the air flow inlet in air channel 500 relative to the inner surface of the second spiral case 200, therefore the second blast of spiral case 200 side near tubular wine wheel 400 region can be increased, make the blast equiblibrium mass distribution in air channel 500, air-out is more steady, also reduce noise to a certain extent.Thus, in the technical scheme combining the first air guide structure 110 and the second air guide structure 210, can prevent air-flow generation in air channel 500 from easily causing eddy current and the turbulent flow of air-out shakiness, different sound, thus reduce wind noise, improve air-out tonequality, reach the effect improving user's comfort.
