Owing to fixing support chip 8 is located on four angles of the square department 2 of ventilation fan framework 4, protrude from square
Portion 2, towards the plane of wall side, when ventilation fan operates, flows to square department 2 through rounded portions 3
Wind can from the square department 2 of ventilation fan framework 4 and gap between the walls through and flow to indoor, i.e.
Leaking out, not only impact ventilation air quantity, also can produce stain because of the generation noise that leaks out simultaneously on wall；
And, through long-term operating, fixing support chip 8 can deform because of vibration and action of gravity,
Thus cause ventilation fan to loosen, produce noise；
And, fixing support chip needs to be additionally installed on ventilation fan framework, not only adds assembling work
Time, and parts are more, there is high in cost of production problem.
Utility model content
The purpose of this utility model is to provide a kind of ventilation fan, its simple in construction, and noise is relatively low.
For achieving the above object, this utility model provides a kind of ventilation fan, including: by towards wall side
Outer frame portion and the ventilation fan framework constituted towards the inner frame portion of indoor, drive wheel rotation
Motor, the support that motor is fixed on ventilation fan framework, the outer frame portion of described ventilation fan framework
Be provided with fixing support chip integral part of with described outer frame portion, described fixing support chip with described towards
The face of the outer frame portion of wall side is that same plane is arranged, and described fixing support chip is provided with fixing use
Perforate.
The utility model has the advantage of, not only can reduce noise, also reduce the component number of product,
Thus reduce assembling man-hour and cost.
Accompanying drawing explanation
Fig. 1 is ventilation fan schematic diagram known to one；
Fig. 2 A is one of total schematic diagram of this utility model embodiment；
Fig. 2 B is the two of total schematic diagram of this utility model embodiment.
Detailed description of the invention
Fig. 2 A is one of total schematic diagram of this utility model embodiment；Fig. 2 B is that this utility model is real
Execute example total schematic diagram two.
As shown in Figure 2 A and 2 B, this utility model embodiment one ventilation fan 10, including: by face
The ventilation fan 10 that outer frame portion 11 to wall side and the inner frame portion 12 towards indoor are constituted
Framework 13, drive impeller 14 rotate motor 15, motor 15 is fixed on the support on framework 13
16, the outer frame portion 11 of framework 13 is provided with fixing support chip 18 integral part of with outer frame portion 11,
Fixing support chip 18 is that same plane is arranged with the face of the outer frame portion 11 towards wall side, fixing
Support chip 18 is provided with fixing perforate.
Outer frame portion 11 in the present embodiment is square, and inner frame portion 12 is circular, four angles pair
Claim.But shape is not limited by this utility model, the most do not limit four angle symmetries.
The surrounding of the outer frame portion 11 of framework 13 is located at by fixing support chip 18, is positioned at as shown in FIG.
Square corner.When ventilation fan 10 operates, it is ensured that fixing of the outer frame portion 11 of framework 13
Blade 18 with fit tightly between the walls.
The face of the outer frame portion 11 that fixing support chip 18 contacts with wall side is that same plane is arranged.
In the planes, the face of fixing support chip 18 contacts with wall side.
By said structure, when ventilation fan 10 is fixed on wall, first by the housing of framework 13
Frame portion 11 is directed at the perforate on wall, and contacts with wall, due to the outer frame portion 11 of framework 13
It is provided with fixing support chip 18 integral part of with outer frame portion 11, and, this fixing support chip 18
It is that same plane is arranged with the face of the outer frame portion 11 towards wall side, so, when by ventilation fan
10 when being fixed on wall, and fixing support chip 18 directly contacts with wall, is then passed by bolt and consolidates
Determine the fixing perforate on support chip 18 and ventilation fan 10 is fixed on wall, like this, Gu
Determine support chip 18 and fit tightly between the walls, when ventilation fan 10 operates, through inner frame portion 12
And the wind flowing to outer frame portion 11 does not haves situation about leaking out.
And, fixing support chip 18, for be integrally formed with outer frame portion 11, decreases the component of product
Number, thus reduce assembling man-hour and cost.
Fix and between support chip 18 and inner frame portion 12, be provided with a plurality of reinforcement 17.When by ventilation fan
10 when being fixed on wall, and fixing support chip 18 directly contacts with wall, is then passed by bolt and consolidates
Determine the fixing perforate on support chip 18 and ventilation fan 10 is fixed on wall, due to ventilation fan 10
Vibration can be produced during operating, add the action of gravity of himself simultaneously, the fixing support of framework 13
Sheet 18 is easily deformed, by arranging plural number between fixing support chip 18 and inner frame portion 12
Individual reinforcement 17, thus improve the intensity of the fixing support chip 18 of framework 13, prevent fixing support chip
18 deform.
A plurality of reinforcements 17 be from inside frame section 12 direction, fixing support chip 18 direction gradually
The step that fall is formed.By step, make framework 13 from inner frame portion 12 to outer frame portion 11 gradually
Gentle transition, flows to the wind of outer frame portion 11 along step through the inner frame portion 12 of framework 13
Mild flowing, is not easily formed turbulent flow, and the flowing making air is more smooth and easy.I.e. reduce air return, fall
Low noise.
Be gradually reduced from inside frame section 12 direction, fixing support chip 18 direction formation step second
Layer is provided with the circular hole 161 of fixed support 16, between second layer step 22 and ground floor step 21
The height of circular hole 161 is highly highlighted not less than the screw 23 of fixed support 16.
Ground floor step 21 refers to the face of fixing support chip 18.By said structure, at a plurality of
In rank, second layer step 22 is the most stable, is arranged on by support 16 on this second layer step 22,
The intensity being conducive to product structure improves.It is additionally, since this second layer step 22 and ground floor step
Height between 21 protrudes from the height of circular hole 161 not less than the screw 23 of fixed support 16, when
After having fixed support 16, the screw 23 of fixed support 16 will not protrude from ground floor step 21,
I.e. screw 23 will not protrude from the face of fixing support chip 18 and interfere with wall, makes consolidating of framework 13
Determine support chip 18 and the most more fit.
