Description
Technical field
The utility model relates to a kind of wind wheel structure of range hood and the blade of wind wheel thereof.
Background technique
The blade of traditional range hood wind wheel adopts middle punching to have the vertical bar shaped of radian usually, and as shown in Figures 1 and 2, the manufacture of wind wheel is shaping more convenient to adopt the advantage of this structure to be, processing is simple.But adopt the rigidity of the wind wheel of this blade structure inadequate, the strength ratio of wind wheel is lower, easily produces mechanical vibration noise.Simultaneously because the radian at the upper and lower two ends of wind wheel blade is consistent with width, make blade exit edge equal with the distance of snail tongue, thus easily cause the air-flow of blade exit to impact snail tongue simultaneously, produce vibration or sympathetic response, cause noise to increase.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of blade and wind wheel thereof of low noise kitchen ventilator wind wheel of excellent noise reduction effect.
For achieving the above object, the utility model adopts following technical proposals:
A wind wheel blade for low noise kitchen ventilator, blade is the sheet bar shaped with long limit and minor face, and described blade bent forms irregular arc.
Described blade bends along short side direction, makes the lateral cross section of described blade form arc, and bends toward opposite side along long side direction simultaneously, makes the longitudinal cross-section of described blade form arc.
Described blade bends along short side direction, makes the lateral cross section of described blade form arc, and simultaneously along long side direction toward same lateral buckling, makes the longitudinal cross-section of described blade form arc.
The radian of described blade lower end is greater than the radian of upper end.
Be provided with a kind of low noise kitchen ventilator wind wheel of above-mentioned blade, it comprises the epipleural of ring, discoidal lower side panel and described blade, and multiple described blade is circumferentially evenly connected between described epipleural and described lower side panel
A kind of low noise kitchen ventilator wind wheel, is made up of two above-mentioned wind wheels, and two lower side panels of described wind wheel splice mutually makes two wind wheel compositions overall.
After adopting technique scheme, compared with prior art, tool has the following advantages the utility model:
1, the utility model adopts the blade of arc to be conducive to strengthening the rigidity of wind wheel, improves the intensity of wind wheel, thus reduces the noise because mechanical vibration produce.
2, the utility model blade design becomes radian, makes to have a curved angle between blade exit and snail tongue, and the outlet at the upper and lower two ends of blade and fan tongue distance unequal, avoid blade exit air-flow and impact snail tongue simultaneously, thus reduce noise.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment one
Be illustrated in figure 3 the blade 1 of the first structure of the utility model, blade is the sheet bar shaped with long limit and minor face, blade 1, along short side direction bending, make the lateral cross section of blade 1 form arc 11, and the radian that the radian of blade lower end is greater than upper end makes the width at the upper and lower two ends of blade inconsistent.Blade 1 bends along long side direction toward opposite side simultaneously, and namely the overbending direction on long limit is contrary with the overbending direction of minor face, makes the longitudinal cross-section of blade 1 form arc.The entirety of blade 1 then forms irregular outer convex, and blade 1 forms inserted sheet 12 respectively at upper/lower terminal.
Be illustrated in figure 4 the low noise kitchen ventilator wind wheel adopting the present embodiment blade 1, it comprises the epipleural 2 of ring, discoidal lower side panel 3 and multiple blade 1, the edge of epipleural 2 and lower side panel 3 circumferentially has multiple jack respectively, the inserted sheet 12 at blade about 1 two ends is separately fixed in the jack of epipleural 2 and lower side panel 3, multiple blade 1 is made circumferentially to be connected to equably between epipleural 2 and lower side panel 3 thus to be assembled into wind wheel in compartment of terrain, without the need to welding, easy for installation.
Embodiment two
Be illustrated in figure 5 the blade 4 of the utility model the second structure, blade 4 is for having the sheet bar shaped of long limit and minor face, blade 4, along short side direction bending, make the lateral cross section of blade 4 form arc 41, and the radian that the radian of blade lower end is greater than upper end makes the width at the upper and lower two ends of blade inconsistent.Blade 4 bends along long side direction toward the same side simultaneously, and namely the overbending direction on long limit is identical with the overbending direction of minor face, makes the longitudinal cross-section of blade 4 form arc.The entirety of blade 4 forms irregular indent arc, and namely contrary with the arcuate directions of embodiment 1, blade 4 forms inserted sheet 42 respectively at upper/lower terminal.
Be illustrated in figure 6 the low noise kitchen ventilator wind wheel adopting the present embodiment blade 4, it comprises the epipleural 2 of ring, discoidal lower side panel 3 and multiple blade 4, the edge of epipleural 2 and lower side panel 3 circumferentially has multiple jack respectively, the inserted sheet 42 at blade about 4 two ends is separately fixed in the jack of epipleural 2 and lower side panel 3, multiple blade 4 is circumferentially connected between epipleural 2 and lower side panel 3 equably thus is assembled into wind wheel, without the need to welding, easy for installation.
The utility model adopts the blade of arc to be not only conducive to strengthening the rigidity of wind wheel, improves the intensity of wind wheel, thus reduces the noise because mechanical vibration produce.And the radian of blade makes to have a curved angle between blade exit and snail tongue, and the outlet at the upper and lower two ends of blade and fan tongue distance unequal, avoid blade exit air-flow and impact snail tongue simultaneously, thus reduce noise.
The wind wheel structure of above-mentioned two embodiment's compositions is not limited to adopt single wind wheel, also can be made up of two wind wheels, and shown in figure 7, the splicing of its lower side panel 3 phase by two wind wheels makes two wind wheel compositions overall.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
