Abstract
The utility model provides a two -sided air inlet scavenger fan, includes and is equipped with the spiral housing in this casing by a casing, it has the wind wheel that has the motor to settle in the spiral housing, be equipped with air intake and air outlet on the casing, its characterized in that: the downside of wind wheel is equipped with down air inlet area, and the upside is equipped with air inlet area, go up air inlet area and all put through the air intake on the casing with lower air inlet area, it is in on the same axial lead to go up air inlet area and lower air inlet area and motor. The utility model discloses mainly be applied to in the scavenger fan to the ventilation efficiency height has, the noise is little and advantage such as long service life.
Description
Technical field
This utility model is related to a kind of ventilation fan, more particularly to a kind of double-faced ventilated ventilation fan.
Background technology
Existing ventilation fan includes a housing, is provided with volute casing in the enclosure interior, and the wind wheel for being provided with motor is placed in volute casing
It is interior.It is provided with air intake area, the as air inlet that the air intake area is connected on housing, one side intake type simultaneously on the downside of wind wheel.
The ventilation fan of this version, as wind wheel single admission can cause axial movement of motor to cause eccentric error, causes motor
Heating reduction of service life.Wind wheel single admission also results in high air-flow velocity, motor speed height and wind wheel anomalous swing simultaneously,
Harsh noise is eventually produced, daily life is have impact on.
The content of the invention
The purpose of this utility model is, in order to solve above-mentioned technical problem, and then to provide a kind of double-faced ventilated ventilation fan.
This utility model by solving the technical scheme that adopts of technical problem is：
A kind of double-faced ventilated ventilation fan, including a housing, are provided with volute casing, are mounted with electricity in the volute casing in the housing
The wind wheel of machine, the housing are provided with air inlet and air outlet.Lower air intake area is provided with the downside of the wind wheel wherein, upside sets
There is upper air inlet area；Upper air inlet area and lower air intake area are turned on the air inlet on housing；At upper air inlet area and lower air intake area and motor
On same axial line.
By implementing above-mentioned technical proposal, this utility model forms bilateral in the lower air intake area of wind wheel and upper air inlet area and enters
Wind, the blast for not only balancing the upper and lower both sides of wind wheel make motor rotation steady, reduce the bias caused because of axial movement of motor
Error, the phenomenon such as the motor feels hot, extend the service life of motor；And compared with prior art, in the premise of identical air quantity
Under can also increase incoming air area, reduce the rotating speed of flow velocity that air-flow flows into and motor, it is steady so as to wind wheel can also swung, significantly
Serve reduce noise effect.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 be in Fig. 1 A-A to sectional view.
In figure：1. housing, 2. volute casing, 3. motor, 4. wind wheel, 5. air inlet, 6. air outlet, 41. upper air inlet areas, under 42.
Air intake area.
Specific embodiment
This utility model is described in further details below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of double-faced ventilated ventilation fan, also has a housing 1, as prior art in the housing
Volute casing 2 is provided with 1, in the volute casing 2, the wind wheel 4 with motor 3 is mounted with, the housing 1 is provided with air inlet 5 and air outlet
6.But this utility model is respectively provided on two sides with upper air inlet area 41 and lower air intake area 42 in the upper and lower of the wind wheel 4, and enterprising
Wind area 41 and lower air intake area 42 are connected with the air inlet 5 on housing 1, and upper air inlet area 41 and lower air intake area 42 and motor 3
On same axial line.So bilateral will be formed in the lower air intake area 42 of wind wheel 4 and upper air inlet area 41 by air inlet 5 to enter
Wind, the blast for not only balancing 4 upper and lower both sides of wind wheel makes 3 smooth running of motor, reduces because 3 axial float of motor causes
The phenomenons such as eccentric error, the heating of motor 3, extend the service life of motor 3；And compared with prior art, in identical air quantity
On the premise of can also increase incoming air area, reduce the rotating speed of flow velocity that air-flow flows into and motor 3, so as to wind wheel 4 can also swung
Steadily, greatly serve the effect for reducing noise.
