The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
Embodiment 1
Fig. 1 is the rearview of air duct blow type air conditioner room unit 14.In this indoor set 14, disposed three desk fan spiral case parts, 2, three desk fan spiral case parts 2 altogether and arranged side by side, wherein, desk fan spiral case parts 2 are arranged on fan electromotor 3 left ends, and all the other two desk fan spiral case parts 2 are arranged on said fan electromotor 3 right-hand members.
Concrete technical scheme is, referring to Fig. 1, Fig. 2 and Fig. 3, said fan electromotor 3 is one, and fan electromotor 3 adopts two spindle motors that go out, and promptly all there is motor shaft at fan electromotor 3 two ends.It is fixing that the motor shaft of said fan electromotor 3 one ends and left end are that the fan 2-1 of one fan spiral case parts 2 is connected; Right-hand member is that two fan 2-1 in two the fan spiral case parts 2 connect with same connecting axle 6; Connecting axle 6 one ends are connected through shaft coupling 5 with the motor shaft of fan electromotor 3, and connecting axle 6 other ends are contained on the bearing external member 8 that is arranged on the blower fan plate 1.So just constituted the technical scheme that a fan motor 3 drives three centrifugal fan 2-1 simultaneously.
When starting fan electromotor 3; The right-hand member of fan electromotor 3 through shaft coupling 5 be in transmission connection the axle 6; Connecting axle 6 drives the centrifugal fan 2-1 rotation air-supply of two desk fan spiral case parts 2 simultaneously, and the motor shaft of motor 3 left ends drives the centrifugal fan 2-1 rotation air-supply of left end one desk fan spiral case parts 2.Air intake gets into indoor set inside from the air inlet 12 of indoor set 14; Regional from the two ends air intake of fan spiral case parts 2 to centrifugal fan 2-1; Under the effect of centrifugal fan 2-1; Wind is blown to evaporimeter 10 by the outlet of spiral case 2-2, blows to indoor through the cold/hot blast of evaporator 10 cooling by air outlet 13.
It is thus clear that; The supply air system of the utility model air duct blow type air conditioner room unit adopts a motor to drive the technical scheme of three centrifugal fans simultaneously; Duoed a desk fan than prior art; Needn't adopt the scheme that strengthens fan diameter in order to improve air quantity, thereby also can not increase the height of indoor set.
Embodiment 2
Different with embodiment 1 is that fan spiral case parts 2 are four, respectively establish two desk fan spiral case parts 2 at each end of a said fan motor 3.Constitute a fan motor 3 and drive four centrifugal fan 2-1 simultaneously.
Concrete technical scheme is; Fan 2-1 in the two desk fan spiral case parts 2 of each end connects fixing with same connecting axle 6; Said connecting axle 6 is connected through shaft coupling 5 with said fan electromotor 3 with the link of said fan electromotor 3, and said connecting axle 6 outer ends are contained on the bearing external member 8 that is arranged on the blower fan plate 1.Be that blower fan plate 1 two ends are provided with bearing external member 8, the outer end of the connecting axle 6 of each side is contained on the bearing external member 8.
In the foregoing description 1,2, said connecting axle 6 is an integrated shaft.Connecting axle 6 diameters of axle are thicker, to satisfy the requirement of prescribed strength and other mechanical performance index.
As variation, connecting axle also can be a segmented, adopts flange or other syndeton to connect in the segmentation joint portion.
It is thus clear that the utility model is to have solved the problem that improves air quantity under the indoor apparatus of air conditioner product height situation not increasing.The supply air system that the utility model is made up of 3 above fan spiral case parts is bigger than the air output of the supply air system that 2 identical fans spiral case parts are formed, thereby has improved air-conditioning performance of products parameter.
The above only is the preferred embodiment of the utility model, is not to be the restriction of the utility model being made other form, and any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.All the utility model technical scheme contents that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belong to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
