Description
Technical field
The present invention relates to a kind of draught fan impeller, specifically a kind of refrigerator centrifugal fan impeller.
Background technology
In wind cooling refrigerator technical field, the fresh keeping property of food is heavily dependent on wind cooling refrigerator storage indoor air flow
The temperature difference in circulation and case between various pieces.The circulation of case interior air-flow is reasonable, and the temperature difference is smaller, then the fresh keeping property of refrigerator is better.
And determine that the whether rational key of airflow circulating of refrigerator is can be blown to multiple places of storing compartment and control is each
The size of local air output.Blade in existing centrifugal fan impeller is installed vertically on the use with connection ring in mounting disc
Serious reduces the area of air inlet, so as to reduce the intake of impeller so that the air-supply efficiency of impeller.Existing centrifugation
The external diameter of the mounting disc of blower fan is general all smaller, and less installation dish external diameter causes each local air output very little, it will
Cause the waste of the energy.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of new centrifugal fan impeller and apply it to ice
Among case.
The invention mainly comprises mounting disc, blade, connection ring and mounting groove, described blade is fixed in mounting disc, respectively
Blade is evenly distributed in mounting disc according to certain angle of inclination；The outer rim of each blade is connected with connection ring；Described peace
Tankage is located at mounting disc center, the installation for motor.
The blade includes the root of blade with mounting disc fixation, the blade tip corresponding with root, close to mounting groove
Vane inside edge and away from mounting disc blade outer rim.End of the thickness of blade from root of blade to blade is gradually thinning,
The inner edge of blade and the end junction of blade are provided with chamfering；The root of multiple blades is uniformly arranged on peace around mounting groove
In sabot, the end of multiple blades tilts extension to away from mounting disc center position.
The upper surface of connection ring is designed to the streamline that rounding is θ by the present invention while diameter of phi of mounting disc is expanded
Type structure.The present invention can reduce vibration on the premise of blower fan volume is not changed and reduce noise, pressure differential be improved, so as to improve
Fan efficiency reaches the purpose of energy-saving and emission-reduction.
Brief description of the drawings
Fig. 1：The overall diagram of device；
Fig. 2：The top view of device；
Fig. 3：The blade figure that above-mentioned centrifugal fan impeller is used.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The present invention includes, mounting disc, blade, connection ring, mounting groove.The root of described blade be fixed in mounting disc and
And multiple blades are distributed in mounting disc in what the arc structure of certain radian was oriented, are formed in the middle of the blade of each oriented alignment
There is center cavity, mounting disc is provided with a motor mounting groove toward center cavity position, wherein being set necessarily in the upper end of motor mounting groove
Fillet, while the inner edge of blade and the end junction of blade set the chamfering of certain angle, is set at each blade outer rim
One curved surface connection ring, makes the end outer rim of each blade be connected with curved surface connection ring, can so cause blade, mounting disc with
Curved surface connection ring is integral type structure, and integral structure can effectively ensure the bonding strength between three, reduce shuttle belt
The noise come.
Embodiment：As shown in Figure 1, Figure 2 and Figure 3, blade and centrifugal blower, including mounting disc 1；Blade 2；Connection ring 3；Electricity
Machine mounting groove 4；End of the thickness of blade from root of blade to blade gradually it is thinning i.e. blade 2 root 21 thickness be more than leaf
The thickness of the end 23 of piece 2, to ensure bonding strength of the blade 2 in mounting disc 1；The root 21 of blade 2 is fixed on mounting disc 1 simultaneously
On, multiple blades 2 are distributed in mounting disc 1 in what the arc structure of certain radian was oriented, in the middle of the blade of each oriented alignment
It is formed with center cavity.Mounting disc is provided with a motor mounting groove 4 toward center cavity position, wherein setting one in the upper end of motor mounting groove
Fixed fillet 41,42, increases the area of air inlet, reduces friction.While the inner edge 24 and the junction of end 23 of blade of blade
The chamfering 25 of certain angle is set, and then the friction between vane inside edge 24 and wind can be reduced and reaches making an uproar for reduction impeller generation
Sound.One curved surface connection ring 3 is set at each blade outer rim 22, makes the end outer rim 22 and curved surface connection ring 3 of each blade
Connection, can so make it that blade 2, mounting disc 1 and curved surface connection ring 3 are integral type structure, integral structure can be effective
Ensure the bonding strength between three, reduce the noise of shuttle belt.And connection ring 3 is provided with fillet 31 and can reduced and rubs
Wipe, increase impeller intake, improve the air-supply efficiency of impeller.
Mounting disc outer diameter D in the present embodiment（120≤D≤140mm）, the outer diameter D of mounting disc and the diameter of curved surface connection ring
Φ is generally equalized（D-Φ≦2mm）, external diameter of the external diameter more than general centrifugal blower mounting disc of this mounting disc.The thickness of mounting disc
Spend and be：t（t≤2mm）, mounting disc internal diameter d (40≤d≤45mm), wherein internal diameter is connected with mounting groove.
The quantity of the present embodiment Leaf be 11, blade it is a length of：L（50≦L≦60mm）, be highly：h（23≦h≦
25mm）, blade inner edge chamfering be：ß（7º≦ß≦12º）.Prolong to away from the inclination of mounting disc center position the end of multiple blades
Stretch and inclined angle is：ε（5º≦ε≦10º）.
The rounding of connection ring described in the present embodiment is：µ（30º≦µ≦45º）, the outer diameter D of mounting disc and connection ring
The difference of diameter of phi is less than 2mm（D-Φ≦2mm）.
To sum up, centrifugal blower small volume, good heat dissipation effect, pressure energy power is strong, noise is low, reasonable in design, simple in construction, cost
Low, the refrigerator with the centrifugal blower has above feature.
