[0050] In the embodiment, the food is not directly baked by using the heating element 1131, but the air heated by the heating element 1131 is driven by the first fan 1132 to enter the accommodation chamber 1111, so that the food can be heated more uniformly, the part of the food in the meal box 2000 can be prevented from being excessively heated and baked, and another part of the food can be prevented from being insufficiently heated. In addition, the influence of the heating element 1131 on the meal box 2000 can be reduced, and the meal box 2000 can be prevented from being deformed by being directly baked by the heating element 1131.

[0051] As an embodiment, please refer to Figure 4 The upper end of the accommodation box body 1110 can be provided with two groups of air supply parts 1115, and the two groups of air supply parts 1115 are arranged symmetrically about the front and back of the accommodation box body 1110. Each group of air supply parts 1115 includes a plurality of air supply ports 1114, and the number of air supply ports 1114 included in the two groups of air supply parts 1115 is the same. The air supply ports 1114 of each group of air supply parts 1115 are arranged in sequence and spaced apart along the left-right direction, so that the heated air can be uniformly supplied into the accommodation chamber 1111.

[0052] In some embodiments, please refer to Figure 2 and Figure 4The side of the accommodating box 1110 is also provided with an air outlet 1116, which is communicated with the accommodating chamber 1111. The heating mechanism 1100 further comprises a preheating box 1140 and an air duct 1150. The preheating box 1140 is connected to the side of the accommodating box 1110, and the preheating box 1140 has a preheating chamber 1141, which is communicated with the air outlet 1116. A heating element 1131 is installed in the preheating chamber 1141, and the heating element 1131 is used to heat the air in the preheating chamber 1141. The air duct 1150 is arranged at the upper end of the accommodating box 1110 and the preheating box 1140, and the air duct 1150 has an air cavity 1151, which is communicated with the preheating chamber 1141 and the air outlet 1114. A first fan 1132 is arranged in the air cavity 1151, and the first fan 1132 can also drive the air in the accommodating chamber 1111 to enter the preheating chamber 1141 through the air outlet 1116. After the air is heated by the heating element 1131, the first fan 1132 can also drive the heated air to enter the accommodating chamber 1111 through the air cavity 1151 and the air outlet 1114 in sequence.

[0053] In the present embodiment, please refer to Figure 3 Under the action of the first fan 1132, the air circulates between the preheating chamber 1141, the air cavity 1151 and the accommodating chamber 1111 in sequence, which not only improves the heating efficiency and avoids heat loss, but also reduces the exhaust emission and is more environmentally friendly.

[0054] As an embodiment, please refer to Figures 1 to 5 The air duct 1150 can have a U-shaped structure, and correspondingly, the air cavity 1151 can have a U-shaped cavity structure. The air cavity 1151 comprises two first cavities 1152 and a second cavity 1153.

The air outlet 1114 is connected to the first cavity 1152, and the first fan 1132 is arranged in the second cavity 1153. When the first fan 1132 works, it will draw the air in the preheating chamber 1141 into the second cavity 1153, and then blow the air in the second cavity 1153 evenly into the first cavity 1152.

[0055] As an example, the heating element 1131 can be a serpentine heating wire.

[0056] As an example, the first fan 1132 can be a centrifugal fan. When hot air baking is needed, the first fan 1132 is started to draw the heated air from the preheating chamber 1141 into the air cavity 1151 by centrifugal action. Then the first fan 1132 blows the heated air into the containing chamber 1111 to bake the food. Then the air in the containing chamber 1111 is drawn into the preheating chamber 1141 by the first fan 1132 to reheat the air, and the internal circulation of the air is thus performed.

The filtering assembly 1160 is used to filter the air entering the preheating chamber 1141 from the containing chamber 1111 to avoid the oil fume entering the preheating chamber 1141. This not only makes the heating device 1000 more sanitary and environmentally friendly, but also avoids the oil fume adhering to the surface of the heating element 1131 to affect the heating effect.

[0058] In some embodiments, referring to Figures 1 to 5 The heating device 1000 further includes a waste gas discharge mechanism 1300. The waste gas discharge mechanism 1300 can discharge the waste gas in the containing chamber 1111 out of the heating device 1000, so that the air in the heating device 1000 can be kept clean, and the food safety is improved.

[0060] As an example, the second fan 1330 is a suction fan.

[0061] In this embodiment, when it is needed to discharge the waste gas in the containing chamber 1111, the second fan 1330 can be started to draw the waste gas in the containing chamber 1111 into the condensate water collecting assembly 1320 to remove the water vapor in the waste gas. Then the waste gas after the removal of the water vapor is discharged to the predetermined area through the air exhaust pipe assembly 1310.

[0062] As an example, referring to Figures 1 to 5As shown, the exhaust pipe assembly 1310 can be connected to the preheating box 1140, and the exhaust gas in the receiving chamber 1111 can enter the exhaust pipe assembly 1310 through the preheating chamber 1141, so that the structure can be effectively simplified, and the exhaust gas in the receiving chamber 1111 can be filtered by the filtering assembly 1160 before entering the exhaust pipe assembly 1310 through the preheating chamber 1141, which is more environmentally friendly.

[0063] In the embodiment, as shown in Figure 2 and Figure 4 , the exhaust pipe assembly 1310 can include a first pipe 1311, a second pipe 1312 and a third pipe 1313 arranged in sequence in a direction away from the preheating box 1140.
