[0025] When the cooking equipment works, the heating element 121 is heated, the first fan 122 is driven to rotate by the motor 123, and the heat generated by the heating element 121 is caused to flow, so that most of the hot air enters the inside of the pot assembly 22 under the guidance of the reflecting disc 11, and this part of the hot air can directly heat the upper surface of the food; a part of the hot air flows to the air return channel through the air return port 111, and enters the inside of the pot assembly 22 through the air inlet 221, and this part of the hot air can directly heat the lower surface of the food, so that the upper and lower surfaces of the food are heated more uniformly. Moreover, the hot air at the bottom of the pot assembly 22 is sucked to the reflecting disc 11 under the back suction action of the first fan 122, and participates in the hot air circulation process again.

[0026] The pot assembly 22 comprises a pot and a guard plate arranged on the front side of the pot, the guard plate is provided with a handle, the front side of the lower shell 2 and the inner container 21 is provided with an opening, the pot is inserted into the inner container 21 through the opening, and the guard plate covers and seals the opening. Figure 2The return air passage is provided as the air guide pipe 3 which is connected with the return air outlet 111 and the air inlet 221, the return air pipe 112 which extends outwardly is arranged on the reflecting disc 11 and at the return air outlet 111, the air inlet pipe 222 which extends outwardly is arranged on the pot body assembly 22 and at the air inlet 221, the air inlet end of the air guide pipe 3 is inserted and fixed outside the return air pipe 112, and the air outlet end is inserted and fixed outside the air inlet pipe 222, so that the air guide pipe 3 can be positioned and the installation and fixation of the air guide pipe 3 are facilitated.

[0027] The inner diameter of the air inlet end and the air outlet end of the air guide pipe 3 is greater than that of the middle part of the air guide pipe 3, when the hot air reaches the middle part of the air guide pipe 3 from the air inlet end, the speed of the hot air increases, so that the hot air can reach the air outlet end more quickly, the transmission speed of the hot air is improved, and the temperature of the hot air is ensured; and the inner diameter of the air outlet end of the air guide pipe 3 is greater than that of the middle part of the air guide pipe 3, when the hot air reaches the air outlet end from the middle part of the air guide pipe 3, the air volume at the air outlet end increases, so that the efficiency of the air outlet is improved, and the heating effect of the hot air on the lower surface of the food is improved.

[0028] It should be noted that the bottom of the reflecting disc 11 is provided with the surrounding edge 113 which extends outwardly, and the inner container 21 and the surrounding edge 113 abut to form the cooking cavity. The surrounding edge 113 is provided with the first installation hole through which the air guide pipe 3 passes, and the first installation hole extends to the outer wall of the surrounding edge 113. The inner container 21 is provided with the second installation hole through which the air guide pipe 3 passes, and the air guide pipe 3 is arranged outside the inner container 21, so that the heat inside the pot body assembly 22 can be prevented from overflowing between the inner container 21 and the surrounding edge 113.

[0029] As an embodiment, the air guide pipe 3 is provided with at least two, and the at least two air guide pipes 3 are located at different sides of the pot body assembly 22, so that the hot air can enter the inside of the pot body assembly 22 from different sides of the pot body assembly 22, and the uniformity of the heating of the lower surface of the food is improved. When the air guide pipe 3 is provided with two, the two air guide pipes 3 are located at the corresponding two sides of the pot body assembly 22, i.e. the air guide pipe 3 is located at the left side and the right side of the pot body assembly 22, so that the uniformity of the heating of the lower surface of the food is further improved; when the air guide pipe 3 is provided with three, the three air guide pipes 3 are respectively located at the left side, the right side and the rear side of the pot body assembly 22, so that the hot air can enter from different sides of the pot body assembly 22, and the uniformity of the heating of the lower surface of the food is improved.

[0030] As another embodiment, in combination with Figure 3The rear side of the upper shell 1 is provided with an air outlet 13, and the upper shell 1 is provided with an air outlet channel 14 communicating with the air outlet 13. The reflecting disc 11 is provided with an air outlet 114 communicating with the air outlet channel 14, so that the excess heat inside the pot assembly 22 enters the air outlet channel 14 through the air outlet 114 and is discharged through the air outlet 13. The air duct 3 is provided with one air outlet 111 located in the air outlet channel 14. Part of the excess heat inside the pot assembly 22 is discharged through the air outlet 114 and the air outlet 13 to ensure the circulation of hot air in the pot assembly 22. Part of the excess heat enters the air duct 3 through the air outlet 111 and enters the pot assembly 22 through the air inlet 221. This can facilitate heat recovery and reduce heat waste while improving the heating uniformity of the lower surface of the food.

[0031] The diameter of the air outlet 111 is greater than that of the air outlet 114, so that most of the heat enters the air duct 3 through the air outlet 111 and enters the pot assembly 22, and a small part of the heat is discharged through the air outlet 114 and the air outlet 13, further reducing heat waste.

[0032] It should be noted that the air outlet 114 is provided with two air outlets 114, and the air outlet 111 is located between the two air outlets 114. When the excess heat in the pot assembly 22 enters the air outlet channel 14 through the air outlet 114 and flows through the upper part of the air duct 3, it can play a heat preservation role for the air duct 3 and ensure the heating effect of the hot air in the air duct 3 on the lower surface of the food.

[0033] In addition, a cold air cavity 16 is provided between the motor 123 and the reflecting disc 11. The cold air cavity 16 is provided with a second fan 161, and the motor 123 is connected with the second fan 161. The second fan 161 rotates under the driving action of the motor 123, which can cool and dissipate heat for the motor 123 and the parts in the upper shell 1. The air outlet channel 14 communicates with the cold air cavity 16, and the cold air in the cold air cavity 16 and the hot air discharged from the air outlet 114 are mixed in the air outlet channel 14, so that the hot air entering the air outlet channel 14 can be quickly cooled, so that the temperature of the hot air finally discharged from the air outlet 13 is reduced, the temperature of the air outlet 13 is effectively reduced, the upper shell 1 is not easily affected by the hot air, thereby improving the overall structural reliability and service life of the upper shell 1, and improving the use safety of the user. The top of the air duct 3 is located in the air outlet channel 14, which can effectively reduce the space occupied by the air duct 3.

[0034] In other embodiments, the reflecting disc 11 is provided with a baffle 17 extending to the air outlet channel 14, the baffle 17 being located above the air guide pipe 3, so that the cold air discharged from the cold air cavity 16 and the hot air discharged from the air outlet 114 are mixed at the air outlet 13, which can not only reduce the temperature at the air outlet 13, but also avoid the cold air discharged from the cold air cavity 16 reaching the air guide pipe 3, thereby reducing the temperature at the air guide pipe 3, so as to ensure the heating effect of the hot air in the air guide pipe 3 on the lower surface of the food.

[0035] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, and therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
