Utility model content
The purpose of the utility model is to provide a kind of guiding device, pass through the special of the special shape of guide shell and blade
Set-up mode can not only play guide functions, and can accelerate the flowing of gas, it is made to generate bigger wind pressure.
Another purpose of the utility model is to provide the blower fan system with above-mentioned guiding device.
Another purpose of the utility model is to provide the range hood with above-mentioned blower fan system.
The utility model is the technical scheme adopted is that a kind of guiding device comprising hyperbolic guide shell and blade, institute
That states that blade is tightly attached to that hyperbolic water conservancy diversion drum outer wall makes blade is axially formed hyperboloid for water conservancy diversion, and blade is along hyperbolic guide shell
Radial direction spiral surrounding is arranged to add to the flowing velocity of air-flow.
The utility model is also characterized by
Blade is at least arranged two and uniformly distributed in hyperbolic guide shell surrounding.
A kind of blower fan system comprising above-mentioned guiding device, spiral case, wind wheel and motor, the motor are arranged in snail
In shell and the output shaft of motor is connected with wind wheel, and the guiding device is located on the panel of wind wheel air inlet.
The utility model is also characterized by
The hyperbolic guide shell be hyperbolic shape big in the end and small in the middle, and in both ends the small one end of diameter close into
It is arranged at air port.
The small one end of the blade diameter is arranged close to air inlet.
Angle in the guiding device between the perpendicular axis direction in windup-degree direction of blade is 20-22 °.
A kind of range hood comprising above-mentioned blower fan system and range hood ontology, the blower fan system setting exist
In range hood ontology.
Compared with prior art, when the utility model is used, blade is being axially formed hyperboloid for water conservancy diversion, in radial side
It can accelerate the flowing velocity of air-flow to spiral surrounding setting, axially and radially collective effect improves wind pressure.
Detailed description of the invention
Fig. 1 is that the utility model embodiment 1 provides a kind of structural schematic diagram of guiding device；
Fig. 2 is that the utility model embodiment 1 provides a kind of structural schematic diagram of hyperbolic guide shell in guiding device；
Fig. 3 is that the utility model embodiment 2 provides a kind of structural schematic diagram of blower fan system；
Fig. 4 is that the utility model embodiment 2 provides a kind of internal structure chart of blower fan system.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model embodiment 1 provides a kind of guiding device, as shown in Figs. 1-2 comprising hyperbolic guide shell 1 and leaf
Piece 2, blade 2, which is tightly attached to 1 outer wall of hyperbolic guide shell, makes the hyperboloid that is axially formed of blade 2 be used for water conservancy diversion, and blade 2 is along hyperbolic
The radial direction spiral surrounding of guide shell 1 is arranged to add to the flowing velocity of air-flow；
In this way, using the above structure, since blade 2 is close to the outer wall setting of hyperbolic guide shell 1, blade 2 is also formed
The hyperbolic configuration similar with 1 shape of hyperbolic guide shell is used for water conservancy diversion, can accelerate air-flow in the setting of radial direction spiral surrounding
Flowing velocity increases wind pressure.
Blade 2 is at least arranged two and uniformly distributed in 1 surrounding of hyperbolic guide shell, the quantity of blade 2 preferably 8, avoids
Arrangement is too many to increase flowing contact area, has an adverse effect to air quantity and noise, arrangement does not have water conservancy diversion and acceleration very little
Effect.
The utility model embodiment 2 provides a kind of blower fan system, as shown in Figure 3-4, the water conservancy diversion dress provided including embodiment 1
It sets, spiral case 3, wind wheel 4 and motor, motor is arranged in spiral case 3 and the output shaft of motor and wind wheel 4 connect, and guiding device is set
On the panel of 4 air inlet of wind wheel；
In this way, using the above structure, air-flow enters before wind wheel 4, air flow direction wind can both be guided by guiding device
Wheel 4, and air-flow can be made to spin up according to the flow direction of blade 2, so that air-flow is obtained initial flow speed and initial pressure, then
Air-flow passes through the rotating boosting again of wind wheel 4, realizes the effect for increasing wind pressure.
The hyperbolic guide shell 1 be hyperbolic shape big in the end and small in the middle, and in both ends the small one end of diameter close into
It is arranged at air port, the small one end of 2 diameter of blade is arranged close to air inlet, in this way, guarantee to occupy lesser air-admitting surface,
It avoids having an impact intake.
Angle in guiding device between the perpendicular axis direction in windup-degree direction of blade 2 is 20-22 °, blade
Vertical axis direction is radial direction, and the torsional direction of blade 2 is tilted to 4 blade direction of rotation of wind wheel, to guarantee the one of front and back wind direction
Cause property, but gradient should not be too big.
The utility model embodiment 3 provides a kind of range hood comprising above-mentioned blower fan system and range hood sheet
Body, blower fan system are arranged in range hood ontology.
Compared with prior art, it in use, guiding device is arranged on the panel of air inlet of kitchen ventilator, can both guide
The original impeller of air flow direction, and air-flow can be made to spin up according to blade flow direction, so that air-flow is obtained rotating boosting twice, can show
The wind pressure for improving range hood is write, oil smoke can also be emptied rapidly by realizing under big back pressure.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
