The chassis 1 of the microwave oven is provided with electrical components of the microwave oven. In a specific solution, as shown in Figure 3, it includes a magnetron 5, a frequency converter 6 and a power supply board 7, etc. These electrical components will generate heat during operation. The generated heat needs to be taken away by the cooling device to maintain the normal operation of the microwave oven. The support member 11 on the outer surface of the chassis 1 plays a role in supporting the microwave oven, and there is a gap between the chassis 1 of the microwave oven and the desktop, so that the air flow can flow into the air inlet 12 and flow out of the air outlet 13 smoothly. The supporting member 11 may be in the form of a foot, a supporting ring or a supporting edge. The air inlet 12 and the air outlet 13 are openings located on both sides of the chassis 1 respectively. In a preferred solution, the air inlet 12 and the air outlet 13 are arrayed strip-shaped holes through which the air inside and outside the base communicates. The shape and size of the air inlet 12 and the air outlet 13 are determined according to factors such as the shape of the electrical components and the amount of heat dissipation. For electrical components with a larger heat dissipation, such as the magnetron 5, a larger air outlet with an area can be set accordingly to reduce the heat dissipation. Timely heat dissipation, one of the specific solutions will be elaborated in the following text. The fan 2 is arranged above the air inlet 12, and sends air at normal temperature or cold air into the microwave oven to cool the electrical components.

Air outlet 13. The wind deflector 3 has various shapes to adapt to the heat dissipation of different electrical components. In order to avoid mutual influence of heat flow among different electrical components, one or several electrical components are separated in separate air ducts through the air deflector 3 to dissipate heat independently. In an independent air channel, the air flow enters from the air inlet 12 under the drive of the fan 2 .

Under the influence of the structure of the air deflector 3, the hot air may directly blow vertically from the air outlet 13 to the table top of the microwave oven, causing the table top to be overheated and damaged. The heat insulating board 4 is arranged on the outer side of the chassis 1 facing the air outlet 13, which prevents the airflow in the direction vertical to the desktop, and flows out of the base from the side of the air outlet 13, reducing the damage to the desktop. The heat insulation plate 4 is detachably connected with the chassis 1, so that it is possible to choose whether to use the heat insulation plate 4 according to the actual situation of the placement position of the microwave oven. heat dissipation efficiency; if the microwave oven is placed on the desktop, then install the heat shield 4 so as not to damage the desktop.

In a specific solution, as shown in FIG. 4 and FIG. 5 , the chassis 1 is disc-shaped, and the heat shield 4 is connected to the chassis 1 by screws. There are four supports 11 evenly distributed on the circumference of the chassis 1. In this solution, legs are used, and the two sides of one of the legs are respectively provided with a first air inlet 12a and a second air inlet 12b. A first air outlet 13a and a second air outlet 13b are provided, that is, the first air inlet 12a is opposite to the first air outlet 13a, and the second air inlet 12b is opposite to the second air outlet 13b. The air inlet 12 and the air outlet 13 are array strip holes, and each air inlet 12 or air outlet 13 is partly located at the bottom of the chassis 1, and partly located at the side of the chassis 1. It can flow out from the side, which provides conditions for the setting of the heat insulation board 4.

As shown in Figure 2 and Figure 6, the air deflector 3 isolates the adjacent first air duct 30a and the second air duct 30b through the middle partition 31, and the positions corresponding to the two ends of the first air duct 30a on the chassis 1 are respectively the first air duct 30a and the second air duct 30b. An air inlet 12a and a first air outlet 13a, the positions corresponding to the two ends of the second air duct 30b are respectively the second air inlet 12b and the second air outlet 13b. The wind deflector 3 also includes a top baffle 33, a first side baffle 32, an oblique baffle 34 and a second side baffle 35, the top baffle 33 covers the first air duct 30a and the fan installation position 36, the first side baffle The plate 32 is provided with an opening 321, located on the side of the first air duct 30a, and the inclined baffle 34 is basically at an angle of 45° to the horizontal plane, connected with the second side baffle 35, and covers the second air outlet 13b. A heat insulating board 4 is disposed opposite to the outer side of the second air outlet 13b of the chassis 1 . The fan 2 is detachably connected to the fan mounting position 36 of the wind deflector 3 . In a specific solution, the fan 2 is connected to the fan mounting position 36 of the wind deflector 3 above the first air inlet 12a and the second air inlet 12b through brackets and screws respectively, and the fan 2 is an air inlet fan, which is detachably connected.

As shown in Figure 3, the inverter 6 of the microwave oven is installed in the first air duct 30a, the power board 7 is installed on the side of the first air duct 30a, and the opening 321 on the first side baffle plate 32 is two rectangular openings, used To help the power board 7 dissipate heat, the magnetron 5 is installed in the second air duct 30b. The airflow generated by the fan 2 is blown into the first air duct 30a from the first air inlet 12a, takes away the heat generated by the frequency converter 6 and the power board 7, and flows out of the base through the first air outlet 13a. The middle partition 31 , the first side baffle 32 and the top baffle 33 restrict the hot air flow in the first air duct 30a, so as not to blow to other electrical components of the microwave oven and affect its normal operation. Since the heat generated by the frequency converter 6 and the power board 7 is relatively small, the hot air is directly discharged from the first air outlet 13a without a heat shield for protecting the desktop. The second air duct 30b is provided with a magnetron 5.

As shown in Figure 4, in order to avoid the impact of strong hot air flow on the desktop below the second air outlet 13b, a heat shield 4 is arranged below the second air outlet 13b, which prevents the air from blowing directly to the desktop, but from The part of the second air outlet 13b located on the side of the chassis 1 flows out of the microwave oven to dissipate heat. The middle partition 31 , the inclined baffle 34 and the second side baffle 35 limit the heat generated by the magnetron 5 in the second air duct 30 b, so as to avoid affecting other electrical components of the microwave oven. The edge of the chassis 1 is provided with an inner mounting ring 14 connected with the microwave oven, and the outer edge of the top baffle 33 is flush with the inner mounting ring 14 . After the base of the microwave oven is integrally connected with the microwave oven through the inner mounting ring 14, the outer edge of the top baffle 33 fits with the furnace wall of the microwave oven, thereby preventing the heat emitted by the parts above the base of the microwave oven from being blown into the base by the air intake fan , affecting the normal operation of electrical components.
