Abstract
The utility model discloses the reinforcement structure of spiral case before a kind of air-conditioning, the front spiral case surface of impeller of blower is provided with multiple arc-shaped convex on the region that each impeller of blower is corresponding dorsad, arc-shaped convex and blower motor are coaxially arranged, advantage is to increase the weight of by arranging arc-shaped convex the weight of spiral case before the air-conditioning of impeller of blower corresponding region, thus adjust the intrinsic frequency in this region, reduce the vibration frequency formed by blower fan Effect of Rotation and produce resonance; As preferably, between the arc-shaped convex of the same area, be provided with the dowel of many radial arrangements, while gaining in weight, reduce the radial direction transmission of vibration.
Description
Technical field
The utility model relates to a kind of component structural of air-conditioning, especially relates to the reinforcement structure of spiral case before a kind of air-conditioning.
Background technology
Before air-conditioning, spiral case is arranged on the front side of blower fan, is thus easily subject to the impact of blower fan rotation and produces vibration, mainly corresponding to impeller of blower region.But under the lightening requirement of air-conditioning, the thickness of front spiral case progressively reduces, make the intrinsic frequency of front spiral case more and more close with the vibration frequency produced by impeller of blower Effect of Rotation, the Oscillation Amplitude of front spiral case near the region of blower fan is because resonance significantly increases; Simultaneously along with the reduction of thickness, intensity is also in reduction, and the vibration of front spiral case also can, to external diffusion centered by blower motor, cause air-conditioning operationally to produce large noise, also causes air-conditioning body vibration simultaneously, affects the stability of operation of air conditioner.Thus, how before reduction air-conditioning while spiral case thickness, can avoid that producing with the vibration frequency formed by blower fan Effect of Rotation resonates and be the priority research areas of those skilled in the art's present stage.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of weight increasing spiral case before air-conditioning a little just to reduce by blower fan Effect of Rotation form the reinforcement structure of spiral case before the air-conditioning of vibration.
The utility model solves the problems of the technologies described above adopted technical scheme: the reinforcement structure of spiral case before a kind of air-conditioning, the front spiral case surface of impeller of blower is provided with multiple arc-shaped convex on the region that each impeller of blower is corresponding dorsad, and described arc-shaped convex and corresponding blower motor are coaxially arranged.
As preferably, between the arc-shaped convex of the same area, be provided with the dowel of many radial arrangements.Gaining in weight, reduction forms vibration simultaneously by blower fan Effect of Rotation, reduces the radial direction transmission of vibration.
Compared with prior art, the utility model has the advantage of the weight of spiral case before the air-conditioning increasing the weight of blower fan corresponding region by arranging arc-shaped convex, thus adjust the intrinsic frequency in this region, reduce the vibration formed by blower fan Effect of Rotation.
As improvement, the arc angle of described arc-shaped convex is 315 °, connects respectively between two dowels of multiple arc-shaped convex with end end points and forms region for arranging blower fan electric wire.Prevent the vibration formed by blower fan Effect of Rotation from blower fan electric wire is cut off by arc-shaped convex.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Shown in figure: 1, spiral case before air-conditioning, 11, arc-shaped convex, 12, dowel.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
This preferred embodiment is illustrated in figure 1 the reinforcement structure of spiral case before a kind of air-conditioning, front spiral case 1 surface of impeller of blower is provided with multiple arc-shaped convex 11 on the region that each impeller of blower is corresponding dorsad, and arc-shaped convex 11 and corresponding blower motor are coaxially arranged; Impeller of blower is located at the inner surface side of front spiral case 1, and front spiral case 1 back side is used for arranging wire structures.The dowel 12 of many radial arrangements is provided with between the arc-shaped convex 11 of the same area.The arc angle of arc-shaped convex 11 is 315 °, connects respectively between two dowels 12 of multiple arc-shaped convex 11 with end end points and forms region for arranging blower fan electric wire.Wherein, by formula for natural frequency
intrinsic frequency f, mass of object m, elastic modelling quantity k; Known when material same elastic modulus k is constant, the intrinsic frequency of this object can be reduced by increment weight m.
