[0025] like Figure 1 and 2In order to dissipate the heat of the microwave generator 3, it also includes a first shell 5 and a second shell 6. The first shell 5 and the second shell 6 are combined to form a first air duct 7. The air inlet of the first air duct 7 is connected to the outside of the box body 1, and the air outlet of the first air duct 7 faces the microwave generator 3. A first fan 8 is arranged in the first air duct 7. The first fan 8 draws cold air outside the box body 1 into the first air duct 7 and blows it toward the microwave generator 3, specifically cooling the microwave generator 3, and having a good heat dissipation effect. At the same time, the cold air can also flow to the area between the box body 1 and the liner 2 for cooling, with a good heat dissipation effect and a low failure rate. Specifically, a first air inlet 120 and a first air outlet 130 are respectively arranged on the rear side of the box body 1. The first air inlet 120 is arranged close to the air inlet of the first air duct 7, and the first air outlet 130 is arranged close to the air outlet of the first air duct 7. The first air outlet 130 can also be arranged at other positions on the box body 1.

[0026] As an example, Figure 3 In order to facilitate the installation of the first fan 8, a mounting groove 510 is provided at one end of the first housing 5 corresponding to the air outlet of the first air duct 7. The first fan 8 is installed in the mounting groove 510 by bolts. The mounting groove 510 is the position of the air outlet of the first air duct 7.

[0027] As an embodiment, in order to facilitate installation, the first shell 5 is arranged on the inner liner 2, and the second shell 6 is arranged on the box body 1, and the first shell 5 and the second shell 6 are abutted against each other to form a first air duct 7. Specifically, the first shell 5 is fixed to the inner liner 2 by a bracket and bolts, and the second shell 6 is fixed to the box body 1 by bolts, which is convenient for installation and disassembly. Specifically, the box body 1 is provided with an opening 110 at a position corresponding to the first shell 5, one end of the second shell 6 is fixed to the box body 1 by bolts, and the other end of the second shell 6 extends into the box body 1 through the opening 110 and is combined with the first shell 5, which is convenient for the installation of the second shell 6.

[0028] As an embodiment, in order to better dissipate the heat of the microwave generator 3, the second shell 6 covers the microwave generator 3, so that more cold air is concentrated on the microwave generator 3, and the heat dissipation effect is good.

[0029] As an example, Figure 4 The upper surface of one end of the second shell 6 is provided with a steam exhaust groove 610, and a through hole 611 is provided at the bottom of the steam exhaust groove 610. The steam exhaust groove 610 is connected with the steam exhaust hole 210 on the inner tank 2 through the through hole 611. The steam exhausted from the steam exhaust hole 210 is discharged outside the box body 1 through the through hole 611. There is no need to set an additional steam exhaust port on the box body 1, and the cost is low. Specifically, a grid is also provided on the steam exhaust groove 610 to prevent debris from entering the steam exhaust groove 610.

[0030] As an example, Figure 1 and 5The inner bottom surface of the box body 1 is provided with a heat dissipation groove 140, and the heat dissipation groove 140 is respectively provided with a second fan 9 and an electrical component 10. The heat dissipation groove 140 is a second air duct. A second air inlet 150 connected to the air inlet of the second air duct and a second air outlet 160 connected to the air outlet of the second air duct are provided on the outer side of the box body 1. The second fan 9 draws cold air from the second air inlet 150 into the second air duct to dissipate the heat of the electrical component 10 and then discharges it from the second air outlet 160, which is specifically used to dissipate the heat of the electrical component 10, especially the electrical component 10 with large heat generation, such as the frequency conversion board, and has high reliability. Specifically, it also includes a cover plate 11, which covers the heat dissipation groove 140, so that the cold air is concentrated in the heat dissipation groove 140, and the electrical component 10 is dissipated separately, and the heat dissipation effect is good.

[0031] Specifically, the box body 1 includes a left side panel, a right side panel, a rear side panel, a top panel, a bottom panel and a door.

[0032] Specifically, the principle of the utility model is that a first shell 5 and a second shell 6 are provided on the outer surface of the inner tank 1, and the first shell 5 and the second shell 6 are combined to form a first air duct 7, and the air inlet of the first air duct 7 is connected to the outside of the box body 1, and the air outlet of the first air duct 7 is aimed at the microwave generator 3 to cool the microwave generator 3. At the same time, the first fan 8 draws cold air outside the box body 1 into the first air duct 7 and then blows it toward the microwave generator 3. The cold air can enter the area between the box body 1 and the inner tank 2 through the microwave generator 3 for cooling, and the heat dissipation effect is good and the failure rate is low.

[0033] Action process: driven by the first fan 8, cold air passes through the first air inlet 120 and the first air duct 7 to blow toward the microwave generator 3 to cool the microwave generator 3, and then the air enters the area between the box body 1 and the inner pot 2 to cool it. It can not only dissipate heat for the microwave generator 3, but also dissipate heat inside the inner pot 2 and the area between the inner pot 2 and the box body 1, and the heat dissipation effect is good.

[0034] On the basis of the above scheme, if various changes or modifications to the utility model do not depart from the spirit and scope of the utility model, and if these changes and modifications fall within the claims and equivalent technical scope of the utility model, the utility model is also intended to include these changes and modifications.
