Specific embodiment

Clearly to illustrate the scheme in the utility model, be given below preferred embodiment and with reference to accompanying drawing specifically It is bright.Application or purposes that the following description is substantially merely exemplary and being not intended to limit the disclosure.It should be understood that , in whole accompanying drawings, corresponding reference represents identical or corresponding part and feature.

As shown in Figure 1, Figure 2 and Figure 4, the utility model provides a kind of blower fan structure suitable for cabinet air-conditioner, the knot Structure composition mainly includes motor liner plate 1, motor 2 and centrifugal fan 3, wherein, motor 2 is fixed on the positive Middle face of motor liner plate 1, The arbor of motor 2 is rotatably coupled towards outside, centrifugal fan 3 with the arbor of motor 2, is installed in by by the blower fan structure In the inside air channel of cabinet air-conditioner, air can be delivered to heat exchanger and air-out from air inlet under the drive of centrifugal blower At mouthful, specifically, in the embodiment accompanying drawing of Fig. 2, air-flow flows out, so as to realize from the Flow in Centrifugal Fans of right side from top Conveyed to air lasting in cabinet-type air conditioner.

In order to improve the stability of the left and right sides air-flow of motor liner plate 1, while heightening the air inflow of centrifugal blower, this practicality It is new that the air-vent that supply stream passes through has been opened up on motor liner plate 1, due to negative pressure can be produced in centrifugal blower rotary course, because The air in the left side of this motor liner plate 1 can under the effect of the pressure of negative pressure automatic stream centrifugal blower, so as to realize centrifugal blower Two-way air intake, increased extra air intake path and intake.

In one embodiment of the present utility model, air-vent includes multiple air inducing groove groups 4, and multiple air inducing groove groups 4 are along electricity Machine liner plate 1 is circumferentially arranged, it is preferred that in order to realize the uniformity in the left side air intake of motor liner plate 1, the setting of air inducing groove group 4 Quantity is chosen as 4 groups, 6 groups and 8 groups, the adjacent interval setting of air inducing groove group 4, so as to while air intake is supplemented, also ensure electricity The structural strength and anti-deformation of machine liner plate 1 itself.

Specifically, each air inducing groove group 4 includes multiple air inducing notches 5, multiple air inducing notches 5 along motor liner plate 1 radial direction Arranged successively laterally from the middle part of motor liner plate 1, the entirety of air-vent is increased to make full use of the plate face of motor liner plate 1 and is entered Wind area.

In one embodiment of the present utility model, it is contemplated that the negative-pressure sucking of centrifugal blower is focused primarily upon in fan The distance of portion, the outermost air inducing notch 5 of same air inducing groove group 4 and the arbor of motor 2, no more than the flabellum of centrifugal fan 3 Outward flange and distance with the arbor of motor 2, i.e., outermost air inducing notch 5 opens up position no more than centrifugal fan 3 The outward flange of blade, to avoid air-flow during duct flows inside cabinet air-conditioner, reversely blows from outermost air inducing notch 5 Go out the problem of (right-to-left in shown in Fig. 2), reduce the influence of flow perturbation.

In one embodiment of the present utility model, because motor liner plate 1 is round-shaped, in order to improve motor liner plate 1 Plate face utilization rate, increase the incoming air area of air-vent, air inducing notch 5 is designed as arc strip, same air inducing groove by this case Multiple air inducing notch 5 of group 4 is located on multiple circular curves of concentric circles each other respectively, it is preferred that the length of air inducing notch 5 Radial direction along motor liner plate 1 gradually increases laterally from middle part, is adapted with the girth with the circular curve for gradually increasing.

In another embodiment of the present utility model, guiding batten is additionally provided with each air inducing notch 5, specifically, being oriented to The bottom of batten is connected with the edge of the side of close motor 2 of air inducing notch 5, is oriented to the top of batten to where centrifugal fan 3 Side bends and towards the periphery of centrifugal fan 3, forms the structure of similar fin, so that the air-flow court flowed into along air inducing notch 5 To centrifugal fan 3 outer circumferential side blow out, this be consider centrifugal blower interior air-flow flow direction be from middle part outwards week flow measurement move, therefore By the guiding batten, can make in the easier inflow indoor set of air-flow in the left side of motor liner plate 1, reduce the gas of different flow directions Interfering between stream.

In embodiment, the length for being oriented to batten is adapted with the length of air inducing notch 5, so as to be oriented to the wind-guiding scope of lath Be adapted with the air intake scope of air inducing notch 5, so flow through the air-flow of same air inducing notch 5 can by it is uniform be guided to from Heart blower fan.

Preferably, it is the arcuate shape being adapted with the shape of air inducing notch 5 to be oriented to batten.

It should be noted that there is abrasion between lath is oriented in order to avoid the flabellum of centrifugal fan 3 is adjacent thereto, knocking The problems such as touching, has gap between centrifugal fan 3 and guiding batten, is oriented to lath and is answered to the height that the bending of centrifugal fan 3 is tilted Less than the width in gap.

As shown in figure 3, in another embodiment of the present utility model, air inducing groove group 4 is independent opening pattern, compared to The structure type that air inducing groove group 4 is made up of multiple air inducing notches 5 in a upper embodiment, can effectively increase in the present embodiment and draw The balance of the both sides air current flow of centrifugal fan 3 is realized in the overall intake in air port, quickening.

The utility model additionally provides a kind of cabinet air-conditioner, including air-conditioner body, and air-conditioner body has above-mentioned blower fan knot Structure.Other parts of air-conditioner body and mechanism do not repeat due to not being related to the novelty of this case.

In sum, above said content is only embodiment of the present utility model, is merely to illustrate original of the present utility model Reason, is not intended to limit protection domain of the present utility model.It is all it is of the present utility model spirit and principle within, that is made is any Modification, equivalent, improvement etc., should be included within protection domain of the present utility model.
