An inner pot 21 is arranged in the lower shell 2. A pot body component 22 is arranged in the inner pot 21. One or at least two food cooking vessels 23 are arranged in the pot body component 22.

[0040] A heating hood 12 is arranged in the upper shell 1, a heating element 112 is arranged in the heating hood 12, an air guide port 122 facing the inside of the pot body assembly 22 is arranged on the heating hood 12; the inner wall of the heating hood 12 forms an inner cavity 161, an air circulation assembly is arranged on the outer side of the heating hood 12, an outer wall of the heating hood 12 is provided with a second air inlet 123 facing the air circulation assembly, and a first air outlet 163 connected to the outside is provided on the inner cavity 161.

[0041] The wind generated by the wind circulation component enters the heating cover 12 through the second air inlet 123, and transfers the heat generated by the heating element 112 to the inside of the pot body component 22 through the air guide 122, so as to heat the food in the pot body component 22. By arranging the heating element 112 in the heating cover 12, the heat is concentrated, the heating efficiency is improved, the food in the pot body component 22 is quickly heated, and the cooking time of the food is shortened; in addition, the excess hot air in the pot body component 22 is discharged through the inner cavity 161 and the first air outlet 163. Since the inner cavity 161 is enclosed by the inner wall of the heating cover 12, the hot air can circulate in the pot body component 22, so that the hot air fully contacts the food in the pot body component 22, and the heating uniformity of the food is improved.

[0042] The longitudinal section of the heating cover 12 is inverted U-shaped, and a heating chamber 121 is formed in the heating cover 12, and an air guide port 122 is arranged at the lower end of the heating cover 12. A connecting portion 125 is formed extending from the periphery of the heating cover 12, and the heating cover 12 and the upper shell 1 are connected by the connecting portion 125.

[0043] The heating hood 12 is located at the lower part of the upper shell 1. Specifically, the heating hood 12 is arranged at the lower port of the upper shell 1 and is located above the pot body assembly 22 to shorten the path of hot air flow, reduce heat loss during the transmission process of hot air, improve cooking effect, and reduce cooking time; at the same time, it effectively suppresses hot air from impacting the top of the upper shell 1 and protects the components on the top of the upper shell 1 from damage.

[0044] In this embodiment, the heating cover 12 is arranged in an annular shape, and the projection of the heating cover 12 on the horizontal plane is located in the pot body assembly 22, which can increase the radiation area of ​​the heat in the heating cover 12 to the food in the pot body assembly 22, shorten the heating time, and improve the heating effect on the food. It should be noted that the heating cover 12 is arranged in an annular shape, which means that the heating cover 12 is arranged around the upper shell 1, and the shape of the heating cover 12 can be adjusted according to the structure of the upper shell 1, and can be set to a circular ring shape or a square ring shape.

[0045] The heating element 112 is arranged around the heating cavity 121, and can be a single heating tube, a heating tube group, a heating plate, etc., which can achieve the purpose and effectively improve the heating value and heating efficiency, and further ensure the heating effect of the food in the pot body assembly 22.

[0046] In this embodiment, the lower end of the heating cover 12 is open to form an air guide 122 to increase the radiation area of ​​the heating element 112 and improve the heating effect on the food in the pot assembly 22; at the same time, the outlet area of ​​the hot air can be increased, further increasing the coverage of the hot air on the food in the pot assembly 22 and improving the heating efficiency. In another embodiment, the lower end of the heating cover 12 is provided with a bottom plate, and the bottom plate is provided with an air guide 122, so that the heating element 112 can be installed on the bottom plate, reducing the difficulty of installing the heating element 112.

[0047] A protective net 126 is provided at the air guide port 122 of the heating cover 12, which plays a protective role while not affecting the hot air passing through the protective net 126 and blowing into the pot body assembly 22, thereby preventing the user from accidentally touching the heating element 112 during use, improving the safety of use, and reducing the possibility of oil stains generated during cooking splashing onto the heating element 112. In other embodiments, the heating element 112 can also be installed on the protective net 126 to further reduce the difficulty of installing the heating element 112.

[0048] In addition, a volute cover 13 is provided on one side of the upper shell 1, and the fan blade 111 is placed horizontally in the volute cover 13. The volute cover 13 includes a spiral cover and an outlet end 132 provided at a tangent of the spiral cover. The outlet end 132 is connected to the side wall of the heating chamber 121. The side wall of the spiral cover is provided with an opening to form an inlet end 131, and the inlet end 131 is located at the upper part of the outlet end 132, and the opening area of ​​the inlet end 131 is larger than the opening area of ​​the outlet end 132. In this embodiment, the fan blade 111 can be set as a cross-flow fan blade, and the fan blade 111 includes a barrel-shaped wind shaft and a blade provided on the wind shaft and inclined outward, and the inclination direction of the blade is consistent with the direction of the outlet end 132.

[0049] It should be noted that one side of the upper housing 1 extends outward to form a spiral cover body so as to install the volute cover 13 and the motor, and the motor shaft of the motor passes through the volute cover 13 and is connected to the wind shaft of the fan blade 111 to drive the fan blade 111 to rotate. An arc-shaped air duct is formed between the volute cover 13 and the inner wall of the spiral cover so as to guide the wind and accelerate the air flow at the volute cover 13. In other embodiments, the spiral cover body can also be arranged in the upper housing 1, and the outer surface of the upper housing 1 is arranged flat.

[0050] The side wall of the heating hood 12 is provided with a second air inlet 123 connected to the outlet end 132 of the volute cover 13, and the outer wall of the heating hood 12 and the first connecting plates 124 are provided on both sides of the second air inlet 123. The first connecting plates 124 are connected to the outlet end 132 of the volute cover 13 to guide the wind blown out by the fan blades 111 into the heating hood 12.

[0051] Specifically, the motor is located on one side of the heating cover 12, that is, not directly above the pot assembly 22, which effectively prevents the hot air inside the pot assembly 22 from moving upward to affect the environment of the motor, and can further reduce the ambient temperature of the motor. Among them, since the fan blades 111 lie horizontally in the volute cover 13, the air outlet area can be increased, the cooking effect can be improved, and the volume of the upper shell 1 can be reduced, making the upper shell 1 more compact as a whole. In this embodiment, the motor and the fan blades 111 are located on the rear side of the upper shell 1; in other embodiments, the motor and the fan blades 111 can also be located on the left or right side of the upper shell 1.

[0052] A first air inlet is provided at the bottom of the lower shell 2 , and an interlayer space 24 is provided between the inner liner 21 and the lower shell 2 . The interlayer space 24 is connected to the first air inlet, and the inlet end 131 of the volute cover 13 is connected to the interlayer space 24 .

[0053] When the fan blade 111 is rotating, external cold air enters the interlayer space 24 through the first air inlet, and the cold air in the interlayer space 24 takes away the heat of the inner pot 21 and the lower shell 2 and then flows to the volute cover 13. Under the action of the fan blade 111, it enters the heating chamber 121 through the second air inlet 123, and transfers the heat generated by the heating element 112 to the inside of the pot body assembly 22 through the air guide port 122, so as to heat the food in the pot body assembly 22.

[0054] In addition, an air hood 14 is provided in the upper shell 1, and the air hood 14 is provided on the heating hood 12, and the bottom end of the air hood 14 is connected to the connecting portion 125, and a cold air cavity 141 is formed between the air hood 14 and the upper shell 1, and the cold air cavity 141 is connected to the interlayer space 24, and the motor and the volute cover 13 are both located in the cold air cavity 141, so that the cold air in the interlayer space 24 enters the cold air cavity 141, and the motor is timely cooled, and the ambient temperature of the motor is reduced, thereby reducing the motor failure rate and increasing the service life of the motor. The side wall of the air hood 14 is provided with an installation port 142 corresponding to the second air inlet 123, and the first connecting plate 124 on the heating hood 12 is connected to the outlet end 132 of the volute cover 13 through the installation port 142.

[0055] As a feasible implementation, the pot assembly 22 includes a pot body 221 and a guard plate 222 disposed on the front side of the pot body 221, a handle is disposed on the guard plate 222, the front sides of the lower shell 2 and the inner pot 21 are both provided with openings, the two openings are connected to form a door body, the pot body 221 is inserted into the inner pot 21 through the door body, and the guard plate 222 covers and seals the door body. A cold air space 223 is disposed in the guard plate 222, and the cold air space 223 is communicated with the cold air cavity 141 and the first air inlet.

[0056] When the fan blade 111 is rotating, external cold air enters the interlayer space 24 and the cold air space 223 through the first air inlet, and the cold air in the interlayer space 24 takes away the heat of the inner pot 21 and the lower shell 2 and flows to the cold air cavity 141. The cold air in the cold air space 223 takes away the heat of the guard plate 222 and flows to the cold air cavity 141, which can dissipate heat and cool down the lower shell 2 and the upper shell 1. The cold air in the cold air cavity 141 flows into the volute cover 13, and enters the heating cavity 121 through the second air inlet 123 under the action of the fan blade 111, and transfers the heat generated by the heating element 112 to the inside of the pot body assembly 22 through the air guide port 122, so as to heat the food in the pot body assembly 22.

[0057] Cold air flows through the upper shell 1 and the lower shell 2, thereby improving the cooling effect of the entire machine. In particular, the first air inlet has a significant effect on reducing the temperature of the bottom of the lower shell 2, avoiding high temperature burns at the bottom or damage to the table top where the cooking equipment is located, thereby improving safety performance.

[0058] As another feasible embodiment, the upper shell 1 is buckled on the lower shell 2, and the upper shell 1 and one side of the lower shell 2 are hingedly arranged, a first retaining ring is arranged on the top of the lower shell 2, and a second retaining ring is arranged on the bottom of the upper shell 1, and the sealing of the pot body assembly 22 is achieved by the first retaining ring and the second retaining ring; the first retaining ring is provided with a first through hole connected to the interlayer space 24, and the second retaining ring is provided with a second through hole connected to the cold air chamber 141, and the first through hole corresponds to the second through hole. When the fan blade 111 is rotating, external cold air enters the interlayer space 24 through the first air inlet. The cold air in the interlayer space 24 takes away the heat of the inner pot 21 and the lower shell 2 and flows to the cold air chamber 141 through the first through hole and the second through hole, and flows into the volute cover 13. Finally, under the action of the fan blade 111, it enters the heating chamber 121 through the second air inlet 123, and transfers the heat generated by the heating element 112 to the inside of the pot body assembly 22 through the air guide port 122, so as to heat the food in the pot body assembly 22.

[0059] It should be noted that the bottom of the lower housing 2 is provided with supporting feet, which are arranged at the four corners of the lower housing to support the lower housing 2, and at the same time, a gap is formed between the lower housing 2 and the desktop for placing the cooking device, so that external cold air can enter the interlayer space 24 through the first air inlet. In other embodiments, the cooking device can also be placed on a desktop with supporting feet, so that there is a gap between the cooking device and the desktop for cold air to enter.

[0060] In addition, an exhaust port 15 is provided on the upper shell 1 or the lower shell 2 to connect the interior of the pot body assembly 22 with the outside world. Excess heat inside the pot body assembly 22 is discharged through the exhaust port 15, thereby forming a complete cycle, which can promptly remove moisture and fat from the food in the pot body assembly 22 to ensure the taste of the food.

[0061] In this embodiment, the exhaust port 15 is arranged at the top of the upper shell 1, and the exhaust port 15 is connected with the inner cavity formed by the inner wall of the heating cover 12. The inner cavity is provided with a first opening toward the inside of the pot body assembly 22 and a first air outlet toward the exhaust port 15, so that the excess heat in the pot body assembly 22 flows to the inner cavity through the first opening, and is discharged through the first air outlet and the exhaust port 15. The fan blade 111 transfers the heat generated by the heating element 112 from top to bottom to the inside of the pot body assembly 22, so that the hot air flows through the periphery of the inside of the pot body assembly 22, and the excess hot air in the pot body assembly 22 flows back from the central area inside the pot body assembly 22 to the inner cavity 161 from bottom to top, thereby realizing the heat circulation inside the pot body assembly 22, thereby increasing the contact area between the hot air and the food, and improving the heating efficiency and the heating uniformity of the food.

[0062] The air outlet 15 is disposed at the rear side of the top of the upper housing 1 to prevent the hot air from being discharged from the air outlet 15 and causing harm to the user.

[0063] Embodiment 2:

[0064] The difference between this embodiment and the above embodiment is that: Figure 6 and Figure 7 An inner cover 16 is arranged in the upper shell 1, and an inner cavity 161 is formed in the inner cover 16. The lower port of the inner cover 16 is provided with a first opening 162 facing the inside of the pot body assembly 22, and the heating cover 12 is arranged on the periphery of the inner cover 16, and the top surface of the inner cover 16 is higher than the top surface of the heating cover 12.

[0065] The inner cover 16 and the heating cover 12 can be an integrated structure to increase the overall structural strength, avoid air leakage through gaps, and ensure the air guiding effect. In other embodiments, the inner cover 16 and the heating cover 12 can also be separately arranged.

[0066] In a possible implementation, combining Figure 8 The inner cover 16 is arranged in a ring shape, and the top wall of the inner cover 16 is connected to the bottom wall of the induced draft cover 14, which improves the overall thermal insulation and heat preservation performance, prevents the heat in the pot body assembly 22 and the inner cavity 161 from being directly transferred to the upper shell 1, and slows down the temperature rise of the upper shell 1.

[0067] In another possible embodiment, combining Fig. 9 The inner cover 16 is a cover body with an inverted U-shape in longitudinal section, and a third opening is provided at a position corresponding to the air hood 14 and the inner cavity 161. The top wall of the inner cover 16 is located at the third opening and is connected to the air hood 14, which effectively reduces the production cost of the air hood while improving the overall thermal insulation performance.

[0068] In another feasible embodiment, the inner cover 16 is a cover body with an inverted U-shape in longitudinal cross-section, and the top wall of the inner cover 16 is connected to the bottom wall of the induced draft hood 14, which can further improve the overall thermal insulation performance. Under the action of the top wall of the inner cover 16 and the top wall of the induced draft hood 14, the heat in the inner cavity 161 can be prevented from being directly transferred to the upper shell 1, thereby slowing down the temperature rise of the upper shell 1.

[0069] In addition, a first air outlet 163 facing the exhaust port 15 is provided on the side wall of the inner cover 16, and second connecting plates 164 are provided on the outer side wall of the inner cover 16 and on both sides of the first air outlet 163. The second connecting plates 164 are connected to the top of the heating cover 12 and the corresponding first connecting plates 124, and are connected to the bottom wall of the induced draft cover 14, and an air outlet channel 165 is formed by the heating cover 12, the induced draft cover 14 and the two second connecting plates 164. It should be noted that the first connecting plate 124 and the corresponding second connecting plate 164 can be provided as a whole, or can be provided separately.

[0070] An exhaust duct 166 is provided between the induced draft hood 14 and the top of the upper shell 1. One end of the exhaust duct 166 is connected to the exhaust port 15, and the other end passes through the induced draft hood 14 and is connected to the outlet passage 165. Excess heat inside the pot assembly 22 is discharged into the exhaust duct 166 through the inner cavity 161 and the outlet passage 165, and is discharged from the outlet 15.

[0071] Among them, the exhaust duct 166 is inclined toward the rear side of the upper shell 1. On the one hand, it is convenient for hot air to enter the exhaust duct 166, and on the other hand, it guides the hot air, effectively preventing the hot air from flowing toward the front side of the cooking equipment after being discharged from the exhaust port 15, which may cause harm to the user.

[0072] Embodiment 3:

[0073] The difference between this embodiment and embodiment 3 is that a first air outlet 163 facing the exhaust port 15 is arranged on the top surface of the inner cover 16 and / or the draft hood 14, and an exhaust duct 166 is arranged between the draft hood 14 and the top of the upper shell 1, one end of the exhaust duct 166 is connected to the exhaust port 15, and the other end passes through the draft hood 14 and / or the inner cover 16 to be connected to the first air outlet 163, so that excess hot air in the pot body assembly 22 flows into the inner cavity 161 and is discharged through the first air outlet 163, the exhaust duct 166 and the exhaust port 15.

[0074] Embodiment 4:

[0075] The difference between this embodiment and the above embodiment is that a third opening is provided at a position corresponding to the inner cavity 161 of the induced draft hood 14, and the inner hood 16 extends upward to the upper shell 1 through the third opening to reduce the overall production cost. It should be noted that the inner hood 16 can be arranged in an annular shape or in an inverted U-shaped longitudinal section.

[0076] When the inner cover 16 is arranged in an annular shape, Fig.10 The exhaust port 15 can be set at a position of the upper shell 1 corresponding to the inner cavity 161 and communicated with the inner cavity 161. The excess hot air in the pot body assembly 22 flows into the inner cavity 161 and is directly discharged through the exhaust port 15.

[0077] In other embodiments, in combination Fig.11 The exhaust port 15 may also be located on one side of the inner cavity 161. In this case, a first air outlet 163 is provided on the side wall of the inner cover 16 and above the induced draft cover 14. An exhaust duct 166 is provided between the first air outlet 163 and the exhaust port 15, so that excess hot air in the pot body assembly 22 flows into the inner cavity 161 and is discharged through the first air outlet 163, the exhaust duct 166 and the exhaust port 15.

[0079] Embodiment 5:

[0080] The difference between this embodiment and the above embodiment is that: Fig.12 and Fig.13 A return air port 167 facing the fan blade 111 is provided on the side wall of the inner cover 16. The fan blade 111 is used to transfer the heat generated by the heating element 112 to the inside of the pot body assembly 22, and under the back-suction action of the fan blade 111, the heat inside the pot body assembly 22 is refluxed to the volute cover 13 through the inner cavity 161 and the return air port 167, so that the hot air inside the pot body assembly 22 is recovered to realize the recycling of the hot air.

[0081] The fan blades 111 transfer the heat generated by the heating element 112 from top to bottom to the inside of the pot body assembly 22, so that the hot air flows through the periphery of the inside of the pot body assembly 22. Under the back-suction effect of the fan blades 111, the hot air flows back from the central area inside the pot body assembly 22 to the inner cavity 161 from bottom to top, thereby realizing heat circulation inside the pot body assembly 22, thereby increasing the contact area between the hot air and the food, and improving the heating efficiency and the uniformity of heating of the food.

[0082] A guide plate 143 is formed at the top of the air inlet hood 14 and extends outward at the installation opening 142. The guide plate 143 divides the inlet end 131 of the volute hood 13 into an air inlet area 133 and a return air area 134. The cold air cavity 141 is connected to the air inlet area 133 of the volute hood 13, and the return air port 167 of the inner hood 16 is connected to the return air area 134 of the volute hood 13. The guide plate 143 is arranged at an angle, which can guide the wind entering the volute hood 13. After the hot air inside the pot body assembly 22 flows back to the return air area 134 of the volute hood 13 through the inner cavity 161 and the return air port 167, it enters the heating cavity 121 again through the outlet end 132 of the volute hood 13 under the guidance of the volute hood 13, thereby improving the heating efficiency and shortening the heating time.

[0083] As a feasible implementation, the return air port 167 is connected to the air outlet channel 165, and the air outlet channel 165 is connected to the inlet end 131 of the volute cover 13, that is, the return air port 167 and the first air outlet 163 are at the same position, which effectively reduces the processing cost and difficulty of the inner cover 16. The wind generated by the fan blade 111 enters the heating chamber 121 through the outlet end 132 of the volute cover 13 and the second air inlet 123, and transfers the heat generated by the heating element 112 to the inside of the pot body 221 assembly 22. At the same time, the hot air inside the pot body assembly 22 flows into the inner cavity 161 under the back suction effect of the fan blade 111, and a part of the hot air is discharged through the first air outlet 163, the air outlet channel 165, the exhaust duct 166 and the exhaust port 15, and the other part of the hot air flows back to the inlet end 131 of the volute cover 13 through the return air port 167 and the air outlet channel 165, and enters the heating chamber 121 again under the action of the fan blade 111, so as to realize the recycling of the hot air.

[0084] As another feasible implementation, a return air channel is provided between the inner cover 16 and the return air area 134 of the volute cover 13, and the return air port 167 is connected to the return air channel, that is, the return air port 167 and the first air outlet 163 are at different positions. The wind generated by the fan blade 111 enters the heating chamber 121 through the outlet end 132 of the volute cover 13 and the second air inlet 123, and transfers the heat generated by the heating element 112 to the inside of the pot body assembly 22. At the same time, the hot air inside the pot body assembly 22 flows into the inner cavity 161 under the back suction effect of the fan blade 111, and flows back to the inlet end 131 of the volute cover 13 through the return air port 167 and the return air channel, and enters the heating chamber 121 again under the action of the fan blade 111, so as to realize the recycling of hot air. At the same time, the excess heat inside the pot body assembly 22 is discharged through the inner cavity 161, the first air outlet 163, the air outlet channel 165, the exhaust duct 166, and the exhaust port 15, so that the air exchange efficiency inside the pot body assembly 22 is higher.

[0086] The difference between this embodiment and Embodiment 5 is that a return air port 167 is provided on the top surface of the inner cover 16, and a return air duct is provided in the upper shell 1, one end of the return air duct is connected to the return air port 167, and the other end is connected to the return air area 134 or the air outlet channel 165 of the volute cover 13, so as to recover the hot air inside the pot body assembly 22 and realize the recycling of the hot air.

[0087] Embodiment 7:

[0088] The difference between this embodiment and the above embodiment is that: the bottom of the lower shell 2 is provided with a first air inlet, and the upper shell 1 is provided with an upper air inlet. The cold air entering from the upper air inlet circulates in the cold air cavity 141. The cold air entering from the first air inlet flows from the interlayer space to the cold air cavity 141, and finally the cold air in the cold air cavity 141 is sucked into the volute cover 13 and the heating cavity 121 under the action of the fan blade 111. The design of the first air inlet and the upper air inlet increases the air suction volume, improves the air exchange efficiency inside the pot body assembly 22, makes the gas flow speed inside the pot body assembly 22 faster, and improves its heating effect and heat dissipation effect.

[0089] In addition, the first air inlet has a significant effect on lowering the temperature of the bottom of the lower shell 2, avoiding high temperature burns at the bottom or browning the table top where the cooking equipment is located, and the safety performance is improved; the cold air sucked in by the upper air inlet has a better effect on absorbing heat and cooling the surface of the motor, effectively reducing the temperature of the motor itself, avoiding the high temperature caused by long-term operation of the motor affecting its operation, and can also withstand higher power motors.
