Limitation.
Below with reference to the accompanying drawings centrifugal blower 10 according to the electromagnetic cooking appliance of the utility model embodiment is described.
As Figure 1-Figure 5, housing is included according to the centrifugal blower 10 of the electromagnetic cooking appliance of the utility model embodiment
200th, motor and impeller 100.
Housing 200 is provided with the first air inlet 211, the second air inlet 212 and air outlet 220.The motor and housing 200
It is connected.Impeller 100 be rotatably provided in housing 200 and the wheel disc including being arranged on the motor be located on the wheel disc
Multiple blades 130, the wheel disc is provided with the air entry 141 that the wheel disc is penetrated along the thickness direction of the wheel disc.Wherein,
First air inlet 211 and the second air inlet 212 are located at the both sides of impeller 100, air outlet 220 respectively in the axial direction of impeller 100
In impeller 100 radially positioned at the outside of impeller 100.
According to the centrifugal blower 10 of the electromagnetic cooking appliance of the utility model embodiment, inhaled by being set on the wheel disc
Gas port 141, air entry 141 can be utilized to connect the first air inlet 211, the second air inlet 212 and air outlet 220.Due to correlation
Blower fan in technology, wheel disc have obstructed the circulation of air-flow, and when wheel disc rotates, air-flow can not flow to opposite side from the side of wheel disc,
The air intake resistance of blower fan is increased, when particularly being applied in IH electromagnetic ovens, due to narrow space in electromagnetic oven, is further reduced
Intake volume.By forming air entry 141, the air-flow of the both sides of impeller 100 can be interconnected by air entry 141.From
When the air-flow of the both sides of heart blower fan 10 is unbalanced, air-flow can flow to opposite side, example by air entry 141 from the side of impeller 100
As shown in figure 3, air-flow directly can not only pass through after the first air inlet 211 enters housing 200 under the driving of impeller 100
Air outlet 220 is discharged, and can be discharged through air entry 141 by air outlet 220, so as to reduce at the first air inlet 211
Intake volume, reduce centrifugal blower 10 air intake resistance, lifted centrifugal blower 10 intake, cooked so as to improve the electromagnetism
Prepare food the radiating effect of utensil, and because air intake resistance reduces, impeller 100 reduces in noise caused by rotation, so as to
It is easy to reduce noise caused by centrifugal blower 10.
Also, by forming air entry 141, because the intake of the centrifugal blower 10 of electromagnetic cooking appliance increases, so
Centrifugal blower 10 do work more, lifted the certain driving air-flow of blade 130 efficiency, can be reduced in the case where ensureing air-supply air quantity from
The rotating speed of heart blower fan 10, so that noise caused by being further easy to the blade 130 of reduction centrifugal blower 10, is easy to improve user's
Comfort.
In addition, by the rational modification of the structure of centrifugal blower 10 to electromagnetic cooking appliance, air-breathing is formed on impeller 100
Mouthfuls 141, it is not necessary to existing electromagnetic cooking appliance others parts are carried out with extra transformation, can be in order to being cooked to existing electromagnetism
The radiator structure of utensil of preparing food carries out transformation and upgrade, is easy to improve the performance of the electromagnetic cooking appliance.
Therefore, radiating effect is had according to the centrifugal blower 10 of the electromagnetic cooking appliance of the utility model embodiment
The good, advantage such as noise is low.
Below with reference to the accompanying drawings centrifugal blower 10 according to the electromagnetic cooking appliance of the utility model specific embodiment is described.
In some specific embodiments of the present utility model, as Figure 1-Figure 5, according to the electricity of the utility model embodiment
The centrifugal blower 10 of magnetic cooking apparatus includes housing 200, motor and impeller 100.
The central axis weight of the central axis of the wheel disc, the central axis of the first air inlet 211 and the second air inlet 212
Close.So can be corresponding with the first air inlet 211 and the second air inlet 212 in order to air entry 141, facilitate access for the first air intake
The air-flow of the air inlet 212 of mouth 211 and second passes through air entry 141, so as to further reduce air intake resistance.
Alternatively, as shown in Figure 1-Figure 3, air entry 141 the first air inlet 211 projection in the plane be located at first
The inner side of air inlet 211, projection of the air entry 141 in the second air inlet 212 institute in the plane are located on the inside of the second air inlet 212.
So air-flow can be further easy to pass through air entry 141 in order to control the size of air entry 141.
Alternatively, the area of air entry 141 is not less than the 30% of the wheel disc area.So it is easy to ensure air entry 141
Area, be easy to air entry 141 to connect the first air inlet 211, the second air inlet 212 with air outlet 220, be easy to air-flow
Opposite side is flowed to from the side of impeller 100.
The wheel disc includes wheel shaft 110, connection ring 120 and multiple spokes 140.Wheel shaft 110 is arranged on the electricity of the motor
On arbor.Connection ring 120 is located at the outside of wheel shaft 110, and multiple blades 130 are arranged at intervals in connection ring 120.Multiple spokes
140 along wheel shaft 110 be provided at circumferentially spaced and the both ends of each spoke 140 are connected with wheel shaft 110 and connection ring 120 respectively, phase
Air entry 141 is formed between adjacent two spokes 140.It can so be easy to ensure impeller 100 in order to the formation of air entry 141
Structural strength.
Specifically, as shown in Figure 4 and Figure 5, the inner of blade 130 is located at the outside of the inside edge of connection ring 120.So may be used
To avoid blade 130 from hindering air-flow to pass through air entry 141.
Fig. 1-Fig. 5 shows the centrifugal blower 10 according to electromagnetic cooking appliance of the present utility model.As shown in Figure 4 and Figure 5,
The outer edge of connection ring 120 is stretched out in the outer end of blade 130.So not only can be in order to increase the area of blade 130, so as to increase
The air output of blade 130, and the area of connection ring 120 can be reduced, further it is easy to reduce intake resistance.
Alternatively, as shown in Figure 4 and Figure 5, spoke 140 is five and along the equally circumferentially spaced of wheel shaft 110.So may be used
So that impeller 100 is more uniformly stressed, it is easy to improve the structural stability of impeller 100.
Specifically, as shown in Figure 4 and Figure 5, the inner width of spoke 140 is more than the width of the outer end of spoke 140.So just
Wheel shaft 110 and connection ring 120 are connected in spoke 140, is easy to improve the structural strength of impeller 100, further improves impeller 100
Structural stability, and because the linear velocity of the outer end of spoke 140 is more inner bigger, can further reduce spoke 140 by
Air drag, so as to further improve electromagnetic cooking appliance centrifugal blower 10 air-supply efficiency.
Alternatively, as shown in Figure 4 and Figure 5, spoke 140 and the junction of wheel shaft 110 and spoke 140 and connection ring 120
Junction arc transition.It so can not only reduce junction and spoke 140 and the connection ring of spoke 140 and wheel shaft 110
The stress concentration of 120 junction, improves the performance of impeller 100, and can further reduce the air resistance of impeller 100
Power.
In another specific embodiment of the present utility model, air entry 141 connects with the outer edge of the wheel disc.So
It equally, in order to the formation of air entry 141, can be easy to ensure the size of air entry 141, so as to further improve electromagnetism cooking pot
The intake volume of the centrifugal blower 10 of tool.
