Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Embodiment of the present utility model provides a kind of double suction air-duct apparatus.Fig. 2 is the perspective view of the double suction air-duct apparatus of the utility model embodiment.As shown in Figure 2, double suction air-duct apparatus comprises spiral case 2, and spiral case 2 has air draught chamber and air-out chamber 3, and air draught chamber is for holding double-suction type centrifugal wind wheel 1, air-out chamber 3 has upper air duct wall 8 and lower air duct wall 4, and the middle part of lower air duct wall 4 has the wind guide tank side direction of wind direction lower air duct wall 4 guided.Utilize double suction air-duct apparatus of the present utility model, because the middle part of lower air duct wall is provided with wind guide tank, the direction of strong wind both sides at middle part are guided, wind can more uniformly be flowed out, this just makes the blast in whole air channel even, vibration alleviates, and noise diminishes, thus provides a kind of comfortable environment to user to greatest extent.
The wind guide tank of double suction air-duct apparatus can comprise: prevailing wind groove portion 5, and prevailing wind groove portion 5 is arranged along the bearing of trend of lower air duct wall 4; At least one left wind guide tank portion 6, left wind guide tank portion 6 extends to the left along prevailing wind groove portion 5; And at least one right wind guide tank portion 7, right wind guide tank portion 7 extends to the right along prevailing wind groove portion 5.The both sides dispersion being arranged so that wind direction prevailing wind groove 5 of left wind guide tank 6 and right wind guide tank 7, further reduces blast.
Fig. 3 is a structural representation of the lower air duct wall of the double suction air-duct apparatus of the utility model embodiment, as shown in Figure 3, left wind guide tank portion 6 and the right wind guide tank portion 7 of lower air duct wall 4 can be that size is identical and symmetrically arranged, so not only make air-out even, and design are succinctly attractive in appearance.
Fig. 4 is another structural representation of the lower air duct wall of the double suction air-duct apparatus of the utility model embodiment, as shown in Figure 4, the left wind guide tank portion 6 of lower air duct wall 4 and the length in right wind guide tank portion 7 can reduce gradually along the bearing of trend of lower air duct wall 4, left wind guide tank portion 6 and right wind guide tank portion 7 can be asymmetric settings, left wind guide tank portion 6 and right wind guide tank portion 7 can be interspersed, quantity also can be different, like this along the flow direction of wind, start with larger groove portion, the high wind at middle part to be shunted as early as possible to both sides, reduce groove portion subsequently, make to weaken wind speed to a great extent.
The each left wind guide tank portion 6 of double suction air-duct apparatus is connected with prevailing wind groove portion 5 with the top in right wind guide tank portion 7, and the end in each left wind guide tank portion 6 and right wind guide tank portion 7 can be in smoothing junction with lower air duct wall 4.Like this, air-flow can be guided smoothly, reduce noise.Wherein, the left wind guide tank portion 6 of double suction air-duct apparatus and the degree of depth in right wind guide tank portion 7 can be reduce gradually from top to end, can certainly be the constant settings of the degree of depth, be not limited to a certain form.
Of the present utility modelly embodiment still provides a kind of air-conditioner, comprise cabinet, have above-mentioned double suction air-duct apparatus in cabinet, make air-out even, blast is little, vibrates little, for user provides more comfortable environment for use.
