Background technique
Range hood has become one of machine for kitchen use equipment indispensable in Modern Family, and air quantity, wind pressure, noise are weighing apparatuses
Measure the core index of range hood performance.However, 85% consumer indicates that range hood suction is small；Blower fan system is as oil suction
The kernel component of smoke machine, very big on the influence of smoke machine performance, blower fan system currently on the market generally only has one stage impeller, therefore
The wind pressure that it is generated is smaller, is not able to satisfy consumer demand.
Summary of the invention
The object of the present invention is to provide a kind of guiding devices, pass through the special shape of guide shell and the special setting of blade
Mode can not only play guide functions, and can accelerate the flowing of gas, it is made to generate bigger wind pressure.
It is a further object to provide the blower fan systems for having above-mentioned guiding device.
It is a further object to provide the range hoods for having above-mentioned blower fan system.
The technical scheme adopted by the invention is that a kind of guiding device comprising hyperbolic guide shell and blade, the leaf
Piece, which is tightly attached to hyperbolic water conservancy diversion drum outer wall, makes the hyperboloid that is axially formed of blade be used for water conservancy diversion, and blade is along the radial direction of hyperbolic guide shell
Direction spiral surrounding is arranged to add to the flowing velocity of air-flow.
The features of the present invention also characterized in that
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 features of the present invention also characterized in that
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, the present invention is in use, blade is being axially formed hyperboloid for water conservancy diversion, in radial direction spiral shell
Rotation can accelerate the flowing velocity of air-flow around setting, and axially and radially collective effect improves wind pressure.
Detailed description of the invention
Fig. 1 is that the embodiment of the present invention 1 provides the structural schematic diagram of guiding device；
Fig. 2 is that the embodiment of the present invention 1 provides the structural schematic diagram of hyperbolic guide shell in guiding device；
Fig. 3 is that the embodiment of the present invention 2 provides the structural schematic diagram of blower fan system；

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention 1 provides a kind of guiding device, as shown in Figs. 1-2 comprising hyperbolic guide shell 1 and blade 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 guide shell
1 radial direction spiral surrounding 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 embodiment of the present invention 2 provides a kind of blower fan system, as shown in Figure 3-4 comprising any one of claim 1-2's leads
Device, spiral case 3, wind wheel 4 and motor are flowed, motor 4 is arranged in spiral case 3 and the output shaft of motor and wind wheel 3 connect, water conservancy diversion dress
It is set on the panel of 3 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 embodiment of the present invention 3 provides a kind of range hood comprising above-mentioned blower fan system and range hood ontology, wind
Machine system is 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 foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of protection of the claims
Subject to.
