Description
Technical field
The utility model relates to a kind of blower fan, relates in particular to a kind of outdoor anti-Water fan that can be used for.
Background technique
In countries such as China and America and Europes, all blower fans that is used for the open air all must be tested by rainwater at present.Therefore this class blower fan need adopt waterproof machine to be used as power and can not adopt common electric machine.Because waterproof machine is the waterproof construction of full closed, therefore for reducing heating value, the consumption of its enameled cable and electric steel is more much bigger than unsealed common electric machine, and manufacturing process and structure be also than common electric machine complexity, thereby make the cost of blower fan of outdoor use be higher than the blower fan of indoor use far away.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and both can prevent that rainwater from drenching motor, can make motor ventilation and heat effectively again simultaneously, as power, is fit to the blower fan of outdoor use with common electric machine.
In order to achieve the above object, the technical solution adopted in the utility model is: described blower fan comprises spiral case, centrifugal fan, motor, the mazy type ventilator, motor shield, two housing sections before and after spiral case is divided into, centrifugal fan is installed in the front and back two housing sections of spiral case, the rear section housing of spiral case and motor shield closure, motor is installed in the end face of the rear section of spiral case, and be shielded in the motor shield, and the rear section housing of spiral case is passed in the rotating shaft of motor and be in transmission connection with centrifugal fan, it is characterized in that: motor shield is provided with the mazy type ventilator, and at the end face of the rear section of spiral case housing exhaust port is set; Described mazy type ventilator comprises the vent hole that is arranged on the motor shield sidewall and a circuitous ventilation flue corresponding with vent hole.
The top of each mazy type ventilator is convexly equipped with a rainproof eaves.
Described exhaust port is the straight-through type exhaust port, perhaps screen type bilateral exhaust port, the perhaps one-sided exhaust port of screen type.
The end face setting of the rear section housing of spiral case makes motor protective housing and mazy type ventilator closely be embedded in wherein circular groove, and the inboard of circular groove is higher than the outside.
Be convexly equipped with manger board in the relative position of mazy type ventilator ventilation flue, manger board is near the mazy type ventilator, and its size can be blocked the mazy type ventilator fully.
The end face of the rear portion housing on the described spiral case also convexes with the waterproof ring of a wound motor.

Embodiment
A kind of outdoor blower fan that can be used for described in the utility model, as shown in Figure 1, its agent structure comprises: spiral case 2, centrifugal fan 3, motor 4, mazy type ventilator 5, motor shield 6, two housing sections before and after spiral case 2 is divided into, centrifugal fan 3 is installed in the front and back two housing sections of spiral case, the rear section housing of spiral case 2 and motor shield 6 closures, motor 4 is installed in the end face of spiral case 2, and be shielded in the motor shield 6, and the rotating shaft of motor is passed the rear section housing of spiral case 2 and is in transmission connection with centrifugal fan 3.
In order to reach ventilation, and the purpose of waterproof, the utility model is provided with mazy type ventilator 5 (as shown in Figure 2) in the both sides of motor shield 6, and at the end face of the rear section of spiral case 2 housing exhaust port 9 (as shown in Figure 3) is set.
Wherein, mazy type ventilator 5 comprises the vent hole 501 that is arranged on motor shield 6 sidewalls and a circuitous ventilation flue 502 corresponding with vent hole.Circuitous ventilation flue 502 can adopt various ways, if its can form a full of twists and turns passage just can, the air in the external world must just can be entered in the motor shield 6 by this tortuous passage.Shown in Fig. 7,8, be respectively two kinds of embodiments of circuitous ventilation flue 502.Flow into ventilation flue 502 in order to reduce extraneous rainwater from vent hole 501, and then enter in the motor shield 6, above each mazy type ventilator 5, be convexly equipped with a rainproof eaves 11.Rainproof eaves 11 can be located at mazy type ventilator 5, also can be located at motor shield 6, and therefore, rainproof eaves 11 can together cast with ventilator 5 or with motor shield 6 again or injection molded unites two into one.Because ventilator 5 is maze-type structures, air can enter the inside of protective housing 6 smoothly through circuitous ventilation flue, and rainwater can't enter the inside of protective housing 6 by mazy passage, makes the mazy type ventilator play the effect of ventilating and intercepting rainwater.The setting of rainproof eaves 11 has then reduced the rainwater that enters ventilator 5.
And exhaust port 9 can adopt the straight-through type exhaust port shown in Fig. 7 a, perhaps the screen type bilateral exhaust port shown in the 7b, the perhaps one-sided exhaust port of the screen type shown in Fig. 7 c.
As shown in Figure 3, be the structural representation of the rear section housing of spiral case 2.Wherein, circular groove 10 is used to make motor protective housing 6 and the mazy type ventilator 5 that is mounted thereon closely is embedded in wherein, and spiral case 2 and motor protective housing 6 are combined closely, and the inboard of circular groove is higher than the outside.Enter motor shield in order further to intercept rainwater, the ventilation flue 502 relative positions of mazy type ventilator 5 are convexly equipped with manger board 7, and manger board 7 is near mazy type ventilator 5, and its size can be blocked mazy type ventilator 5 fully.In addition, the rear side of the rear portion housing on spiral case 2 also convexes with the waterproof ring 8 of a wound motor, and to stop the rainwater flow direction motor that may infiltrate, waterproof ring 8 offers a wire outlet hole 15, makes things convenient for drawing of motor power-supply wire.The structure that manger board 7 and waterproof ring 8 can adopt branch shown in Figure 3 to be arranged, also can adopt integral structure as shown in Figure 4, manger board 7 and waterproof ring 8 are integrated, and with together cast or injection molded with spiral case 2, the three is integrated, and structure is more compact.
As shown in Figure 5, in the bottom of motor shield 6 weep hole 12 is set.Weep hole 12 adopts the transverse drainage setting, to reduce rainwater is splashed into protective housing 6 by ground chance.It is firm that supporting foot 13 is placed whole typhoon machine.Lead channels 14 is to be some specific use, conveniently draws electric power connection line and establishes.
The working principle of outdoor blower fan described in the utility model is as follows: during fan operation, the rotation of centrifugal blade, make spiral case 2 and motor shield 6 form negative pressure, the outer cool air of blower fan enters the inside of protective housing 6 by mazy type ventilator 5, after carrying out heat exchange with motor 4, the heat that motor sends is taken away by exhaust port 9, made motor 4 radiating and coolings.Because ventilator 5 is mazy circuitous ventilation flue structures, air can enter the inside of protective housing 6 smoothly through circuitous channel, and rainwater can't enter the inside of protective housing 6 by mazy passage.The mazy type ventilator has played the effect of ventilating and intercepting rainwater.Rainproof eaves 11 has reduced the rainwater that enters ventilator 5.The rainwater of the minute quantity that 7 further obstructs of manger board may be splashed into by ventilator 5.Waterproof ring 8 intercepts the minute quantity rainwater that may infiltrate or be splashed in the protective housing 6, make its can not flow direction motor etc. live part, and discharge by weep hole 12.
