Embodiment
Fig. 5 illustrates the ssembly drawing of the utility model one embodiment's fan.Fig. 6 illustrates the exploded view of the utility model one embodiment's fan.Shown in figure 5 and Fig. 6, the cooling fan 500 of the present embodiment comprises mounting plate 501, motor 502, centrifugation blade 503 and fairing cap 504.Motor 502 is arranged on mounting plate 501.Centrifugation blade 503 is also arranged on mounting plate 501 and by motor 502 and drives.Specifically, mounting plate 501 can have the first contrary attachment face A and the second attachment face B.It is upper that motor 502 is arranged on the first attachment face A, and centrifugation blade 503 is arranged on the second attachment face B.The live axle of motor 502 passes mounting plate 501 to insert in the bearing of centrifugation blade 503.Fairing cap 504 forms fastening structure to hold centrifugation blade 503 with mounting plate 501.Form thus a complete centrifugal cutter.
In the present embodiment, on the fastening structure forming at fairing cap 504 and mounting plate 501, arrange that wind guiding structure is to control the air-out direction of centrifugal cutter.Wind guiding structure can comprise one or more exhaust outlets.Specifically, fastening structure can have the first exhaust outlet 511, and this first exhaust outlet 511 has the first air-out direction F1.The first air-out direction is a part for the circumference of corresponding fan only, and therefore the air-out direction of fan can be determined and concentrate.For instance, the first exhaust outlet 511 can be positioned at the end face of fan, and therefore the first air-out direction F1 is for upwards.
In addition, fastening structure can have the second exhaust outlet 512, and this second exhaust outlet 512 has the second air-out direction F2.The second air-out direction F2 can be different from the first air-out direction.For instance, the second exhaust outlet 512 can be positioned at a leading flank of fan, and therefore the second air-out direction F2 is for forward.
Certainly, in another embodiment, the second air-out direction F2 and the first air-out direction F1 also can be identical, and just the first exhaust outlet 511 is different with the second exhaust outlet 512 positions, is used for the diverse location of microwave oven to carry out cooling.
Fig. 7 illustrates the sectional view of the utility model one embodiment's fan.Fan shown in Fig. 7 has the example of two exhaust outlets.Shown in figure 7, the first exhaust outlet 511 and the second exhaust outlet 512 have respectively different air-out directions.For instance, two air-out directions can be substantially mutually vertical.
Continue with reference to figure 7, centrifugation blade 503 can be according to turning clockwise.Be helix structure as the fastening structure of fan drum, and preferably according to " spiral of Archimedes " design, loss minimum when air quantity is circled round in inside.Specifically, fastening structure has the first helix 513 at the profile at these the first exhaust outlet 511 places.Fastening structure has the second helix 514 at the profile at these the second exhaust outlet 512 places.This first helix 513 and/or this second helix 514 can be spiral of Archimedes.
Like this, by two exhaust outlets, air quantity is reasonably distributed, the corresponding different cooled region of different exhaust outlets forms independently wind path, cooling more better effects if.
In addition, centrifugal cutter 500 preferably has larger air intake scope, to can obtain enough air outputs.In one embodiment, the fastening structure of centrifugal cutter 500 can have the first intake grill and the second intake grill, and this first intake grill and the second intake grill are towards different directions.
Fig. 8 illustrates that the utility model one embodiment's fan is at the scheme of installation of microwave oven internal.Shown in figure 8, centrifugal cutter 500 can be according to the rear and low part in microwave oven control room 800.The benefit that is arranged on this position is to obtain fresh air from the outside in control room 800.When fan 500 is installed to control room 800 when interior, the first exhaust outlet 511 of fan frequency converter assembly (not shown) to microwave oven upward, the second exhaust outlet 512 can be faced forward the magnetron (not shown) of microwave oven, thereby can provide cooling air to carry out cooling to these two parts.
In addition, when fan 500 is installed to the control room 800 of microwave oven when interior, the rear side 800a (for microwave oven front panel) that its first intake grill can Control-oriented chamber 800, the bottom side 800b of the second intake grill Control-oriented chamber 800.As can be seen, the rear side 800a in control room 800 and bottom side 800b are respectively equipped with suction port 801 and 802.
Further, fan 800 also can arrange the 3rd intake grill in the position of side, Control-oriented chamber.On the outer cover of side, control room, can reserve suction port to allow the 3rd intake grill air inlet.
Although embodiment above illustrates centrifugal cutter and has two exhaust outlets, but is appreciated that size, quantity and the position of exhaust outlet can change according to the parts layout in control room.For example, centrifugal cutter can only have the exhaust outlet of a face forward.
Or centrifugal cutter can have more exhaust outlet.Fig. 9 illustrates the stereogram of another embodiment's of the utility model fan.Shown in figure 9, this fan has three exhaust outlets, except aforesaid the first exhaust outlet 511 and the second exhaust outlet 512, is positioned in addition the 3rd exhaust outlet 513 on the covering of the fan of fan with the 3rd air-out direction F3.
Fig. 9 illustrates that the utility model one embodiment's fan is in the arranged direction of microwave oven internal.As shown in Figure 9, the rotating shaft of fan 500 is that left and right directions is arranged, therefore fan is less than the width at fore-and-aft direction at the width of left and right directions, is also less than the width at above-below direction, and this is conducive to dwindle the width of control room at left and right directions.
In sum, the utility model embodiment's microwave oven and cooling fan thereof have the following advantages with respect to existing fan:
1, by the wind-guiding design on mounting plate and air guide sleeve, allow cooling fan there are the controlled one or more exhaust outlets of air-out direction, therefore allow centrifugal cutter to be disposed in the control room of microwave oven sidepiece;
2, by the multiple intake grills that reserve on mounting plate and air guide sleeve, make the air output of cooling fan large, improve cooling effect.
3, by allowing the rotating shaft left and right directions of cooling fan arrange, fan is minimized at the width of left and right directions, dwindled the width of control room at left and right directions.
Although the utility model is described with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, in the situation that not departing from the utility model spirit, also can make variation or the replacement of various equivalences, therefore, as long as the variation to above-described embodiment, modification all will drop in the application's the scope of claims within the scope of connotation of the present utility model.
