Description
Technical field
The utility model belongs to ventilator technical field, particularly a kind of centrifugal blower.
Background technique
Centrifugal blower is a kind of for carrying the machinery of gas, and it is applied to very at large and produces and live in various field.For a long time, existing centrifugal blower, its spiral case only arranges an exhaust outlet all usually, and air wants rotating 360 degrees could draw from exhaust outlet at most inside spiral case, and therefore efficiency is low, and wastes energy.And when needing a Fans to different both direction balanced ventilation, need external elbow could realize the object of blowing to different direction.But owing to being equipped with outer tube joint, make the fabricating cost of product increase, complex structure, and it substantially increases air-line system internal resistance, make air quantity little, efficiency is low, air-supply weak effect.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide that a kind of structure is simple, air-supply efficiency is high, and can to the centrifugal blower of multiple directions air-supply.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of centrifugal blower, comprise spiral case, motor and impeller, described impeller is placed in described spiral case, described motor is fixed on the top of described spiral case, its rotating shaft is inserted in described spiral case and is connected with described impeller, the bottom of described spiral case is provided with intake grill, and the side of described spiral case is at least provided with the exhaust outlet that array is carried out in two rotating shafts around described motor, and described in these, the airflow direction of exhaust outlet is identical.
Preferably, the side of described spiral case is provided with two exhaust outlets, and these two exhaust outlets are at a distance of 180 degree.
Preferably, described spiral case is made up of top board, base plate and the side plate be fixed between the two, and described motor is fixed on described top board, and described intake grill is provided with on described base plate; Described side plate is made up of two pieces of identical circular arc plates, and described exhaust outlet is formed by between the head end of described circular arc plate and end.
Preferably, the end of described circular arc plate is connected with one block of straight plate one tangent with described circular arc plate, and described straight plate one is connected with one block of straight plate two to described spiral case internal deviation.
Pass through technique scheme, the centrifugal blower that the utility model provides, by arranging multiple exhaust outlet on spiral case, can be drawn from exhaust outlet as long as such air revolves turnback at most in impeller inspiration spiral case afterwards, accelerate the speed of air flowing, thus the efficiency of blower fan can be improved, save the energy, and balance is better, noise is less.Meanwhile, this centrifugal blower can reach a Fans simultaneously to multiple different direction balanced ventilation when blowing, and without the need to other adjunction elbow, can reduce and install elbow and reduce air-line system resistance, effectively improve air-supply efficiency, and it be effective to blow.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the side structure schematic diagram of a kind of centrifugal blower disclosed in the utility model embodiment;
Fig. 2 is the structural representation of the spiral case disclosed in the utility model embodiment;
Fig. 3 is the floor map of the spiral case disclosed in the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1 be a kind of centrifugal blower, comprise spiral case 11, motor 12 and impeller 13, impeller 13 is placed in spiral case 11, motor 12 is fixed on the top of spiral case 11, its rotating shaft is inserted in spiral case 11 and is connected with impeller 13, the bottom of spiral case 11 is provided with intake grill 14, and the side of spiral case 11 is provided with the exhaust outlet 15 that array is carried out in two rotating shafts around motor 12, and these exhaust outlets 15 are at a distance of 180 degree and airflow direction is identical.
See Fig. 2 and 3, spiral case 11 is made up of top board 11a, base plate 11b and the side plate 11c be fixed between the two, and motor 12 is fixed on top board 11a, and intake grill 14 is provided with on base plate 11b; Side plate 11c is made up of two pieces of identical circular arc plates, and exhaust outlet 15 is formed by between the head end of circular arc plate and end.The end of circular arc plate is connected with one piece of straight plate one 11d tangent with circular arc plate, and straight plate one 11d is connected with one piece of straight plate two 11e to spiral case 11 internal deviation.The design of straight plate one 11d and straight plate two 11e adds air-supply effect.
The utility model, by arranging multiple exhaust outlet on spiral case, can be drawn from exhaust outlet as long as such air revolves turnback at most in impeller inspiration spiral case afterwards, accelerate the speed of air flowing, thus the efficiency of blower fan can be improved, save the energy, and balance is better, noise is less.Meanwhile, this centrifugal blower can reach a Fans simultaneously to multiple different direction balanced ventilation when blowing, and without the need to other adjunction elbow, can reduce and install elbow and reduce air-line system resistance, effectively improve air-supply efficiency, and it be effective to blow.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
