For further setting forth the utility model for the technological means reaching predetermined model utility object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment of test stand, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.In the following description, the not necessarily same embodiment that different " embodiment " or " embodiment " refers to.In addition, special characteristic, structure or feature in one or more embodiment can be combined by any suitable form.
As depicted in figs. 1 and 2, the structural representation of fan that provides of the utility model embodiment one.As shown in Figure 1, a kind of fan described in the present embodiment comprises: blower-casting 10 and blast fan 20.Described blower-casting 10 is provided with intake grill 11.Described blast fan 20 is arranged in described blower-casting 10, and described blast fan 20 can rotate relative to described blower-casting 10.As shown in Figure 2, described blast fan 20 comprises wheel hub 21 and M flabellum 22.The axis of described wheel hub 21 overlaps with the center line of described intake grill 11 and arranges, and M described flabellum 22 ring is located on the wheel rim of described wheel hub 21.At least one flabellum 22 in M described flabellum 22 is the first flabellum 22, and described first flabellum 22 comprises the first end face 221, second end face 222 relative with described first end face 221, the 3rd end face 223, four end face 224 relative with described 3rd end face 223.Described first end face 221 is the end face of described first flabellum 22 and described wheel hub 21 joint; Described 3rd end face 223 is connected with described first end face 221 and described second end face 222 respectively, and relative with face, described intake grill 11 place.Wherein, an end face is had at least to be the positive integer of curved surface or inclined-plane, M >=1 in described first end face 221, described second end face 222, described 3rd end face 223 and described 4th end face 224.Wherein, the curvature of described curved surface can set according to actual conditions, and model utility is embodiment be not specifically limited.
In the present embodiment, as shown in Figure 1, described blower-casting comprises top board, base plate and side plate.Described base plate, described top board and described side plate surround the containing space for accommodating described blast fan jointly; Described top board is provided with described intake grill, on described base plate or described side plate be provided with exhaust outlet.Wherein, the center of wheel hub described in more described second tip to face distance of described first end face of described first flabellum is comparatively near, and described second end face is relative with described side plate, and described 3rd end face is relative with described top board, and described 4th end face is relative with described base plate.Owing to having at least an end face to be curved surface or inclined-plane in described first end face, described second end face, described 3rd end face and described 4th end face, make when the fan 33 is operated, the linear velocity that each flabellum of described fan is respectively pointed out is different, make air-flow different relative to the flow velocity of described flabellum, to make the wind speed at described fan outlet place different, each flabellum is caused to produce the sound wave of crest and the interlaced superposition of trough; Or, each point on described first flabellum of described fan is different apart from the distance of blower-casting, make air-flow different to the pressure of described blower-casting, described blower-casting is caused to be subject to the damp impacts of air-flow, fundamentally inhibit the generation of eddy current crack, reduce eddy current noise result better, improve sound quality.
An end face is had at least to be curved surface or inclined-plane in first end face 221 described in above-described embodiment, described second end face 222, described 3rd end face 223 and described 4th end face 224.Respectively each end face is specifically described below:
