Abstract
The utility model discloses an improved centrifugal wind wheel, which comprises a bottom plate, blades, a border and a wave position, wherein the wave position and the blades are positioned on the same side of the bottom plate. The improved centrifugal wind wheel is characterized in that a plurality of annularly distributed S-shaped or wavy stress dispersion structures are arranged on the mirror image side of the bottom plate connected with the blades. The stress dispersion structures formed by a plurality of S-shaped grooves or raised lines are arranged on the mirror image side of the bottom plate connected with the blades, so that dynamic balance can be effectively reduced and even eliminated in the using process of the improved centrifugal wind wheel, and the effects of lowering the production cost and improving the production efficiency are achieved; moreover, the improved centrifugal wind wheel is reliable in structure; and when the improved centrifugal wind wheel falls off, joints of the blades and the bottom plate are effectively prevented from being fractured under the pulling action of the stress dispersion rings, and deformation can also be prevented in a transportation process. The improved centrifugal wind wheel is simple and reliable in structure and low in production cost, and can be widely applied to various indoor cabinet air conditioners.
Description
Technical field
The utility model relates to the wind wheel field, particularly a kind of improved centrifugal wind wheel.
Background technique
Be used for the centrifugal wind wheel on the indoor air conditioner cabinet in the existing technology; As shown in Figure 1; Comprise base plate 1, blade 2, frame 3 and ripple position 4, some radiation holes 41 (ripple position 4 also can not be provided with radiation hole 41) are arranged on the ripple position 4, ripple position 4 and blade 2 are positioned at the same side of base plate 1; There is following problem in the centrifugal wind wheel of this structure: one, computing ballance correction is big, has increased cost of production and has reduced manufacturing efficiency; Two, weight is big, waste material; When three, falling, blade and back plate connections easy-rupturing or distortion.So existing centrifugal wind wheel is difficult to satisfy consumers in general's requirement.
Summary of the invention
The purpose of the utility model is to above-mentioned existing problems and deficiency; Provide a kind of and not only can effectively reduce computing ballance correction; Even can accomplish to exempt from dynamic balancing; Can reduce production costs and enhance productivity, but also can prevent the improved centrifugal wind wheel of the problem such as fracture and distortion of blade and back plate connections effectively.
The technological scheme of the utility model is achieved in that
The said improved centrifugal wind wheel of the utility model; Comprise base plate, blade, frame and ripple position; Wherein said ripple position and blade are positioned at the same side of base plate, are characterized in: the image side that is connected with blade at said base plate is provided with several " S " shapes or the waveform stress dispersed structure that distributes ringwise.
The concrete structure of wherein above-mentioned " S " shape or waveform stress dispersed structure can come fixed as required; As for to make the utility model can effectively reduce on the basis of computing ballance correction; But again economical with materials with reduce production costs and weight reduction, above-mentioned stress dispersed structure can be " S " connected in star of being arranged on the above-mentioned base plate and forms; For the utility model can effectively reduced on the basis of computing ballance correction, can play certain wind-guiding effect again and to the bottom plate structure reinforcement effect, above-mentioned stress dispersed structure can also form for " S " shape raised line that is arranged on the above-mentioned base plate.
The utility model is owing to be employed in the stress central dispersion structure that image side setting that base plate is connected with blade is formed by the groove or the raised line of some S shapes; Make the utility model in the process of using; Can effectively reduce computing ballance correction, even accomplish to exempt from dynamic balancing, reach the effect that reduces production costs and enhance productivity; And reliable in structure; And when falling, prevented the fracture of blade and back plate connections effectively owing to there be pulling of stress central dispersion to draw effect, also can prevent distortion in the transportation process simultaneously.The utility model is simple in structure, reliable, cost of production is low, can be widely used on the various indoor air conditioner cabinets.
Below in conjunction with accompanying drawing the utility model is further described.

Embodiment
Like Fig. 1-shown in Figure 5; The said improved centrifugal wind wheel of the utility model; Comprise base plate 1, blade 2, frame 3 and ripple position 4; Wherein said ripple position 4 and blade 2 are positioned at the same side of said base plate 1, and for effective structural reliability that reduces the computing ballance correction when centrifugal wind wheel moves and strengthen the utility model, the image side that is connected with blade 2 at said base plate 1 is provided with several " S " shapes or the waveform stress dispersed structure that distributes ringwise.Make the utility model in the process of using; Not only can reduce computing ballance correction, even accomplish to exempt from dynamic balancing, to reach the effect that reduces production costs and enhance productivity; And when falling; Prevented the fracture of blade and back plate connections owing to there be pulling of stress central dispersion to draw effect effectively, also can prevent distortion in the transportation process simultaneously, so reliable in structure.The concrete structure of wherein above-mentioned " S " shape or waveform stress dispersed structure can come fixed as required; As for to make the utility model can effectively reduce on the basis of computing ballance correction; But economical with materials is carried with the wind that reduces production costs and alleviate motor again; Like Fig. 2-shown in Figure 3, above-mentioned " S " shape stress dispersed structure can be " S " connected in star 5 that is arranged on the above-mentioned base plate 1.The concrete width and the degree of depth as for above-mentioned " S " connected in star 5 can be confirmed according to the size and the thickness of centrifugal wind wheel and base plate 1.For making the utility model can effectively reduce on the basis of computing ballance correction; Can play certain wind-guiding effect again and to the bottom plate structure reinforcement effect; Like Fig. 4-shown in Figure 5, above-mentioned " S " shape stress dispersed structure is that " S " shape raised line 6 that is arranged on the above-mentioned base plate 1 forms.The concrete width of above-mentioned " S " shape raised line 6 can be confirmed according to the size and the thickness of centrifugal wind wheel and base plate 1 with height.Several " S " shape stress dispersed structures that distribute ringwise on the above-mentioned base plate 1 can also be to be combined to form with " S " shape raised line 6 by some " S " connected in star 5 that is arranged on the above-mentioned base plate 1.Can not establish radiation hole on the above-mentioned in addition ripple position 4.Certainly, also some radiation holes 41 can be set on above-mentioned ripple position 4 in order to make its radiating effect in running better.The utility model is simple in structure, reliable, cost of production is low, can be widely used on the various indoor air conditioner cabinets.
Although the utility model is to describe with reference to specific embodiment, this description does not also mean that the restriction of the utility model formation.With reference to the description of the utility model, other of the disclosed embodiments change, and all can expect to those skilled in the art, and this variation should belong in the affiliated claim institute restricted portion.
