Describe in detail according to micro-wave oven of the present utility model below with reference to accompanying drawing.
As shown in Figures 1 to 4, according to micro-wave oven of the present utility model, comprising: body of heater 100, door body 200, fan 300, magnetron 400, transformer 500 and fluid dividing cover 600.
Particularly, in body of heater 100, there is cooking cavity (not shown) and electrical equipment chamber 102.Wherein, rear (as shown in Figure 1 arrow after indicated direction) wall of electrical equipment chamber 102 is configured to wind-guiding orifice plate 1021.
Door body 200 is pivotably mounted on body of heater 100 to open and close described cooking cavity.
Fan 300 be arranged in electrical equipment chamber 102 and be positioned at wind-guiding orifice plate 1021 before (as shown in Figure 1 arrow before indicated direction) face.
Magnetron 400 be arranged in electrical equipment chamber 102 and be positioned at fan 300 before.
Transformer 500 be arranged in electrical equipment chamber 102 and be positioned at magnetron 400 under (as shown in Figure 1 arrow under indicated direction) face.Upper (as shown in Figure 1 arrow on indicated direction) spaced surface preset distance of the lower surface of magnetron 400 and transformer 500.Transformer 500 has upper and lower spaced apart primary coil 501 and secondary coil 502.
Fluid dividing cover 600 is arranged in electrical equipment chamber 102 and between magnetron 400 and transformer 500.
Advantageously, as depicted in figs. 1 and 2, according to an example of the present utility model, fluid dividing cover 600 is connected with magnetron 400.
Further, as shown in Figure 3 and Figure 4, fluid dividing cover 600 comprises the pedestal 601 being connected with the lower surface of magnetron 400 and the baffle plate 602 being connected with the front end of pedestal 601.Predetermined oblique angle between pedestal 601 and baffle plate 602.For example, the predetermined angular of inclination can be 90 °-180 °, can determine according to the concrete installation site of magnetron 400 and transformer 500.
Further, as shown in Figure 1, the length of the projection of baffle plate 602 on the perpendicular perpendicular to front and back (as shown in Figure 1 indicated direction before and after arrow) direction is not less than the spacing between the lower surface of magnetron 400 and the upper surface of transformer 500.Thus, can will farthest be directed to by the cooling air between magnetron 400 and transformer 500 on the transformer 500 of below, radiating effect is better.
According to micro-wave oven of the present utility model, between magnetron and transformer, fluid dividing cover is installed, the cooling air of flowing through between magnetron and transformer can be guided on transformer, promote air-cooled efficiency, good heat dissipation effect.

According to an example of the present utility model, fluid dividing cover 600 can be one-body molded with magnetron 400.Thus, simplify technique.
In other words,, according to micro-wave oven of the present utility model, between magnetron 400 and transformer 500, fluid dividing cover 600 is set.Fluid dividing cover is divided into two parts, and one is pedestal 601, is fixed on magnetron 400 belows, and another part is baffle plate 602, tilts with respect to pedestal 601.
Fluid dividing cover 600 can adopt metal or nonmetallic materials to form.In the time that fan 600 blows out cooling air, most of for cooling magnetron 400, the air quantity of magnetron 400 and transformer 500 center-aisle parts, is put together by fluid dividing cover 600, has blowed to transformer 500 under oblique.Now, the primary coil 501 on transformer 500 and secondary coil 502, can obtain a large amount of cooling air heat radiations, and the temperature rise of transformer 500 can significantly be reduced.
If fluid dividing cover 600 adopts such as the metal material such as aluminium sheet, aluminium alloy plate, because fluid dividing cover 600 is connected with magnetron 300, can also increase the area of dissipation of magnetron 300, further reduce the temperature rise of magnetron 300, extend the life-span of magnetron 300.The fluid dividing cover 600 of metal material be equivalent to the extend fin area of magnetron 300.
Fluid dividing cover 600 non-metallic materials such as plastics, with low cost, be shaped convenient.
The shape of fluid dividing cover 600 can be square baffle plate.Pedestal 601 is for being fastened on magnetron 400, and fixed form can lock with screw, or directly detain at the fourth of the twelve Earthly Branches.Baffle plate 602 is obliquely installed, and can, for changing wind direction, wind be blown out from original level, becomes under oblique and blows to the transformer 500 that is positioned at its below, increases the air cooling effect of transformer 500.Baffle plate 602 is obliquely installed the area of dissipation that also contributes to increase magnetron 400.
According to micro-wave oven of the present utility model, the radiating effect of entirety is better, and magnetron 400 and the transformer 500 of caloric value maximum all can effectively be dispelled the heat, and make its temperature rise be able to further reduction, extends the life-span of key components and parts.Because the temperature rise of magnetron 400 and transformer 500 can reduce, so can further optimize the design of magnetron 400 and transformer 500, reach the object that reduces volume, weight reduction.
