A first vent 131 is provided on the motor frame 13 and at a position corresponding to the second fan blade 16, so that the receiving chamber 15 and the cold air chamber 14 are connected.

[0034] A first air inlet 4 is provided between the top cover 3 and the upper shell 1. The first air inlet 4 is provided at the bottom of the top cover 3 and is evenly distributed along the periphery of the top cover 3.

[0035] The design of the first air inlet 4 and the second air inlet 5 increases the air intake volume, improves the air exchange efficiency in the accommodating chamber 15 and the cold air chamber 14, makes the gas flow faster, and improves the heat dissipation effect. The cold air sucked in from the first air inlet 4 has a better effect on absorbing heat and cooling the surface of the motor 113, effectively reduces the temperature of the motor 113 itself, avoids the high temperature caused by the long-term operation of the motor 113 affecting its operation, and can also withstand higher power motors 113; the cold air sucked in from the second air inlet 5 flows through the upper shell 1, the motor frame 13 and the corresponding area of ​​the heating element 112, avoids the accumulation of heat at the bottom of the upper shell 1, and thus improves the safety performance and service life of the upper shell 1.

[0036] Among them, the second air inlet 5 is arranged on the left and right sides of the upper shell 1 and is evenly distributed along the width direction of the upper shell 1, which can further increase the air intake and improve the overall heat dissipation effect. It can also take in air from the left and right sides of the upper shell 1 to dissipate heat and cool down the area corresponding to the upper shell 1, the motor frame 13 and the heating element 112, further reducing the probability of heat accumulation in the area.

Specifically, a windshield block 51 is arranged on the inner wall of the upper shell 1 and located at the second air inlet 5. The windshield block 51 is hollow, and an inlet facing the second air inlet 5 is arranged on the windshield block 51. An outlet is arranged on the top of the windshield block 51, and the inlet and the outlet are connected.

[0039] It should be noted that the third air inlet 6 is arranged on the rear side of the upper shell 1, and there are two groups of third air inlet 6. The two groups of third air inlet 6 are distributed at both ends of the rear side of the upper shell 1. Cooperating with the second air inlet 5, air can be introduced from different directions, which can fully dissipate heat and cool down the areas corresponding to the upper shell 1, the motor frame 13 and the heating element 112, further avoiding heat accumulation in the area, and the number of second air inlets 5 can also be arbitrarily set according to the expected heat dissipation effect.

[0040] The upper shell 1 is provided with an exhaust port 7 which connects the cold air chamber 14 with the outside. The exhaust port 7 is arranged between the two groups of third air inlets 6. The cold air sucked in through the first air inlet 4, the second air inlet 5 and the third air inlet 6 enters the accommodating chamber 15, and enters the cold air chamber 14 through the first vent 131 on the motor frame 13. After cooling and dissipating the heat of various components in the upper shell 1, the cold air is discharged from the exhaust port 7 to realize a complete cold air circulation. In addition, the exhaust port 7 is arranged in the cold air chamber 14 and close to the side of the second fan blade 16, which shortens the air outlet distance of the second fan blade 16, increases the external exhaust speed, increases the air outlet volume, increases the overall air flow speed, and makes the cooling effect on the motor 113 and the upper shell 1 more significant.

The cold air in the cold air cavity 14 enters the transition exhaust cavity 8 to cool down the side wall of the upper shell 1 close to the transition exhaust cavity 8, further avoiding heat accumulation at the bottom of the upper shell 1, thereby improving the safety performance and service life of the upper shell 1.

[0045] Specifically, the motor frame 13 extends downward to form a protective ring 9, and the second fan blade 16 is arranged in the protective ring 9, and the bottom of the protective ring 9 is lower than the bottom of the second fan blade 16, so that the air suction capacity of the second fan blade 16 can be improved, so that the external cold air enters the accommodating cavity 15 through the first air inlet 4, the second air inlet 5 and the third air inlet 6 under the suction of the second fan blade 16, and enters the protective ring 9 through the first vent 131 on the motor frame 13. There is a gap between the bottom wall of the protective ring 9 and the top surface of the air guide plate 12, so that the cold air in the protective ring 9 can enter the transition exhaust cavity 8 and other cold air cavity 14 areas through the gap, cool the motor frame 13 and the upper shell 1, and improve the overall safety performance.

[0046] Embodiment 3:

[0047] The difference between this embodiment and embodiment 2 is that: Figure 7 The upper shell 1 is provided with an exhaust cavity 71 connected with the exhaust port 7, and each cold air cavity 14 is provided with a cold air duct 72 connected with the exhaust cavity 71, so as to guide the cold air in the cold air cavity 14 into the exhaust cavity 71, and then discharge the upper shell 1 from the exhaust port 4. During the cooking process, the excess heat in each cold air cavity 14 is discharged into the exhaust cavity 71 through the cold air duct 72, and then discharged through the exhaust port 7. Multiple cold air cavities 14 share one exhaust port 7, which can reduce the manufacturing difficulty and production cost of the cooking device.

[0048] In addition, each cooking cavity is provided with an exhaust duct 73 connected to the exhaust cavity 71, so as to guide the hot air in the cooking cavity into the exhaust cavity 71, and then be discharged from the upper housing 1 through the exhaust port 7. During the cooking process, the excess heat in each cooking cavity is discharged into the exhaust cavity 71 through the exhaust duct 73, and then discharged through the exhaust port 7. Multiple cooking cavities share one exhaust port 71, which effectively reduces the possibility of users being burned by hot air when using or approaching the cooking device, improves the safety of use, and can also reduce the manufacturing difficulty and production cost of the cooking device.

[0049] The cold air in the cold air chamber 14 flows into the exhaust chamber 71 through the cold air duct 72, so that the cold air and hot air in the exhaust chamber 71 are mixed and discharged from the exhaust port 7, effectively reducing the temperature at the exhaust port 7 and further improving the safety of use.

[0050] Among them, the exhaust port 7 is arranged on the rear side of the upper shell 1. When the hot air in the cooking cavity is discharged through the exhaust cavity 71 and the exhaust port 7, it will not affect the user's operation on the front side of the upper shell 1, and can further avoid the risk of the user being scalded by hot air when using or approaching the cooking equipment.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
