Abstract
The utility model relates to the field of the ventilators, in particular to a centrifugal ventilator with the function of bidirectional air supply. The centrifugal ventilator comprises a shell body, an outer rotor motor and an impeller, wherein the impeller is arranged in the shell body and is electrically connected with the outer rotor motor, the outer rotor motor is fixed on the shell body by a bracket, the shaft end of the impeller is provided with an air inlet, the shell body is provided with a first air outlet and a second air outlet which are in diagonal distribution, and the first air outlet and the second air outlet are respectively provided with an independent power supply switch. The bidirectional centrifugal ventilator has small contour dimension and low manufacture cost, adopts two air outlets, can simultaneously realize unidirectional or bidirectional air supply and is quick and convenient to install and connect.
Description
Technical field
The utility model relates to the ventilator field, is specifically related to a kind of centrifugal blower with two-way air-supply function.
Background technique
Ventilator has obtained using widely as important ventilation equipment, and existing ventilator boundary dimension is bigger, the fabricating cost height, and have only an exhaust outlet, can only realize unidirectional air-supply, when the two-way air-supply of needs, pipeline is made comparatively complicated, uses extremely inconvenient.
The model utility content
The technical problems to be solved in the utility model provides that a kind of boundary dimension is little, and fabricating cost is low, and can realize the centrifugal blower of two-way air-supply easily.
The technological scheme that the utility model adopted is such: a kind of two-way centrifugal blower, comprise housing, external rotor electric machine and impeller, described impeller places in the housing and with external rotor electric machine and is connected, described external rotor electric machine is fixed on the housing by support, the axle head of described impeller is provided with intake grill, being provided with on the described housing is first exhaust outlet and second exhaust outlet that the diagonal angle distributes, and described first exhaust outlet and second exhaust outlet are respectively equipped with independently power switch.
Described housing is a scroll casing shape.
Described first exhaust outlet and second exhaust outlet are parallel to each other.
By adopting above-mentioned technological scheme, the beneficial effects of the utility model are: the centrifugal blower of the two-way air-supply of the utility model, and boundary dimension is little, fabricating cost is low, and two exhaust outlets are arranged, and can side by side realize unidirectional or two-way air-supply, installation connects efficient and convenient.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of the utility model Fig. 1.
Embodiment
As Fig. 1, shown in Figure 2, a kind of two-way centrifugal blower, comprise housing 2, external rotor electric machine 7 and impeller 6, described impeller 6 places in the housing 2 and with external rotor electric machine 7 and is connected, described external rotor electric machine 7 is fixed on the housing 2 by support 3, the axle head of described impeller 6 is provided with intake grill 4, being provided with on the described housing 2 is first exhaust outlet 1 and second exhaust outlet 5 that the diagonal angle distributes, the Way out of described first exhaust outlet 1 and second exhaust outlet 5 is parallel to each other, one left, one is to the right, the centrifugal blower of the two-way air-supply of the utility model, and working principle and common single vent centrifugal aerator are identical, just can be from two exhaust outlets 1,5 to different ventilation duct air-supplies, and be respectively equipped with independently power switch, and can realize unidirectional or two-way air-supply simultaneously, make, use all very convenient.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
