Abstract
The utility model discloses a dual-discharge fan, which comprises two scroll casings; the scroll casing contains an air inlet and an air outlet; an impeller is arranged inside the two scroll casings respectively; an intermediate isolating plate which divides the two scroll casings into two independent spaces is arranged between the two scroll casings. The two impellers are connected with the same driving shaft; one end of the driving shaft extends out of scroll casing and is connected with the driving device. The dual-discharge fan has the function of two fans of air inlet and air discharge. The device is used in heat recovery unit, air conditioning unit, and fresh air ventilation unit, the total size of unit is reduced; weight is lessened so as to reduce product cost, save energy.
Description
Technical field
The utility model goes out wind apparatus about a kind of pair, more particularly, and about a kind of two air-out blower fans that are used on heat recovery unit, air-conditioning unit, the fresh air ventilator.
Background technique
At present, known pair of air intake centrifugal formula blower fan (comprising outer rotor blower fan and bel-drivenn blower fan) all has only an exhaust outlet, that is to say to transfer out one air-flow.When two strands of air-flows of needs output, existing fresh air ventilator and air conditioner need to select for use two typhoon machines more, and promptly one is used for air intake, and another is used for air draft.Owing to two typhoon machines are set in same unit, will inevitably strengthen the volume and weight of unit itself, thereby increase the cost of unit, and waste energy.
Summary of the invention
The purpose of this utility model is to provide a kind of pair of air-out blower fan, utilizes this pair air-out blower fan can replace two typhoon machines, has advantages such as the unit of dwindling overall dimension, minimizing weight.
Two air-out blower fans in the utility model include two spiral cases, described spiral case includes an intake grill and an exhaust outlet, be provided with a central diaphragm that is used for two separate space of two spiral cases formation between described two spiral cases, in the inner separate space that forms of described two spiral cases, be respectively equipped with an impeller that drives by same drive unit.
Have an angle between the exhaust outlet of described two spiral cases, described angle is between the 0-180 degree.
Described drive unit includes a live axle that is connected with described two impellers simultaneously, and an end of this live axle extends a spiral case and is connected with a driving mechanism.
Be connected by belt, belt pulley between described live axle and the described driving mechanism.
Described drive unit includes an external rotor electronics that directly is arranged on a described spiral case inside, and the external rotor of this external rotor electric machine is fixedlyed connected with described impeller.
Two air-out blower fans in the utility model have the function of air intake, air draft two typhoon machines, it is applied in heat recovery unit, air-conditioning unit, the fresh-air ventilation unit, can dwindles the overall dimension of unit, reduce weight, thereby have the reduction cost, save advantages such as the energy.
Description of drawings
Fig. 1 is that the master of two air-out blower fan embodiments one in the utility model looks schematic representation;
Fig. 2 is the schematic side view of two air-out blower fan embodiments one in the utility model, and this there is shown the internal structure of two air-out blower fans;
Fig. 3 is the structural representation of two air-out blower fan embodiments two in the utility model.
Embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment one
As depicted in figs. 1 and 2, the two air-out blower fans in the present embodiment include two spiral cases, i.e. spiral case 1 and spiral case 2.Each spiral case 1,2 has included an intake grill 11,21 and an exhaust outlet 12,22, wherein intake grill 11,21 is positioned at axial (positions at live axle 8 places) position of spiral case 1,2, and intake grill 12,22 is positioned at the radial position of spiral case 1,2, and have an angle between two intake grills 12,22, this angle is between 0 to 180 degree.Two spiral cases 1,2 fuse by a central diaphragm 3, and spiral case 1,2 inside are separated into two spaces 4 and 5 independently, wherein in space 4 and 5, be respectively equipped with an impeller 6 and 7, wherein impeller 6 is connected with live axle 8 by fixing device 9 with 7, that is to say by same live axle 8 to drive that an end of this live axle 8 extends spiral case 1 (also can be spiral case 2) and is connected with drive unit by belt, belt pulley (also can be other known kind of drive).
The working principle of two air-out blower fans is in the utility model:
Utilize 8 rotations of drive unit drive live axle, and further drives impeller 6,7 is rotated, and air-flow is entered from intake grill 11,21 respectively, exports from exhaust outlet 21,22 respectively after impeller 6,7 pressurizes, thereby can realize exporting the purpose of two strands of air-flows.The air quantity of two strands of air-flows, blast can be adjusted according to shape, the size of diameter, width and the blade of impeller 6,7, and according to the direction that is provided with of blade, can export the air-flow of equidirectional or different direction.
Embodiment two
Basic identical in two air-out blower fans in this enforcement and the foregoing description one, and having identical function uses identical label to illustrate with the parts of structure, its unique difference is that two impellers 6,7 in the present embodiment are directly driven by the external rotor electric machine (not shown) that is located at a spiral case 1 inside, as shown in Figure 3, the rotor that is external rotor electric machine directly is connected with impeller 6, and drives impeller 6,7 rotations, because this structure is a prior art, therefore describe in detail no longer separately.
Two air-out blower fans in the utility model can also be by direct forming behind the spiral case integrator of two typhoon machines.
Two air-out blower fans in the utility model are being applied to recuperation of heat unit, air-conditioning unit, fresh-air ventilation Have in the time of in the machine and save volume, reduce floor space, simplify set structure, the advantage such as reduce the fault point.
Claims (5)
