[0032] Embodiment 1:

[0033] The present application embodiment discloses a cooking device, such as Figure 1 As shown, it includes an upper shell 1 and a lower shell 2. A heating device and an air circulation component are arranged in the upper shell 1. The air circulation component includes a fan blade 111 and a motor for driving the fan blade 111 to rotate; an inner pot 21 is arranged in the lower shell 2, a pot body component 22 is arranged in the inner pot 21, and one or at least two food cooking utensils 23 are arranged in the pot body component 22.

[0034] An inner cover 16 is provided in the upper shell 1, and an inner cavity 161 is formed in the inner cover 16. A first opening 162 facing the inside of the pot body assembly 22 is provided at the lower end of the inner cover 16, and a return air port 167 facing the air circulation assembly is provided on the inner cover 16, and a first air outlet 163 communicating with the outside is provided on the inner cover 16; a heating device is provided on the periphery of the inner cover 16, and the air circulation assembly is provided on the outside of the heating device. The air circulation assembly transfers the heat generated by the heating device to the pot body assembly 22. After heating the food, the hot air inside the pot body assembly 22 flows into the inner cover 16 under the back-suction action of the air circulation assembly, and a part of the hot air is discharged through the first air outlet 163, and the other part of the hot air flows back to the air circulation assembly through the return air port 167 and enters the pot body assembly 22 again, so that the hot air in the pot body assembly is recovered, and the hot air is recycled, which can improve the heating efficiency and shorten the heating time.

[0035] Specifically, the heating device includes a heating cover 12 and a heating element 112 disposed in the heating cover 12. The heating cover 12 is disposed on the periphery of the inner cover 16. The longitudinal section of the heating cover 12 is in an inverted U-shape. A heating cavity 121 is formed in the heating cover 12. The top surface of the inner cover 16 is higher than the top surface of the heating cover 12. 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 disposed.

[0036] A connecting portion 125 is formed by extending the periphery of the heating cover 12 , and the heating cover 12 and the upper shell 1 are connected via the connecting portion 125 .

[0037] In a feasible embodiment, the inner cover 16 is annularly arranged, extending upward to the upper shell 1, and connected to the upper shell 1, which can ensure the relative sealing of the inner cavity 161, while reducing the production cost of the inner cover 16. In another feasible embodiment, the longitudinal section of the inner cover 16 is an inverted U-shaped arrangement, and the top of the inner cover 16 is higher than the top of the heating cover 12, which can further improve the overall thermal insulation performance and heat insulation performance. Under the action of the top wall of the inner cover 16, 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.

[0038] The heating cover 12 is arranged at the lower end of the upper shell 1 and is arranged in an annular shape, that is, the heating cavity formed by the heating cover 12 is arranged in an annular shape, and the projection of the heating cavity 121 on the horizontal plane is located in the pot body assembly 22, which can increase the radiation area of ​​the heat in the heating cavity 121 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 inner cover 16, 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.

[0039] In this embodiment, the projection of the heating cover 12 on the horizontal plane is located at the periphery of 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 can also heat the food in the outer circle of the inside of the pot body assembly 22, thereby improving the heating efficiency and the uniformity of heating of the food.

[0040] The heating element 112 is arranged around the heating cavity 121, and can be a single heating tube, a heating tube group, 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.

[0041] In addition, 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 feasible 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.

[0042] A protective net 126 is provided at the air guide port 122 of the heating chamber 121, and the protective net 126 can be connected to the heating cover 12 or to the bottom plate, and plays a protective role while not affecting the hot air passing through the protective net 126 and blowing to the inside of 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.

[0043] In addition, the motor and the fan blade 111 are both located on one side of the heating chamber 121, that is, not directly above the pot body assembly 22, which effectively prevents the hot air inside the pot body assembly 22 from moving upward and affecting the environment of the motor, and can further reduce the ambient temperature of the motor.

[0044] Among them, 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 arranged at the 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. The opening area of ​​the inlet end 131 is larger than the opening area of ​​the outlet end 132, and the inlet end 131 is connected to the return air port 167. 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 arranged on the wind shaft and inclined outward, and the inclination direction of the blade is consistent with the direction of the outlet end 132.

[0045] It should be noted that one side of the upper shell 1 extends outward to form a spiral cover body so as to install the volute cover 13 and the motor. 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. The cold air in the interlayer space 24 enters the inlet end 131 of the volute cover 13 through the arc-shaped air duct so as to guide the cold air and accelerate the air flow at the volute cover 13. In other embodiments, a spiral cover body can also be set in the upper shell 1, and the outer surface of the upper shell 1 is flat. Since the fan blade 111 lies horizontally in the volute cover 13, the air outlet area can be increased and the cooking effect can be improved. In addition, the space in the upper shell 1 can be reasonably utilized to make the upper shell 1 more compact as a whole. In this embodiment, the motor and the fan blade 111 are located at the rear side of the upper shell 1; in other embodiments, the motor and the fan blade 111 can also be located on the left or right side of the upper shell 1.

[0046] In addition, a return air port 167 facing the inlet end 131 of the volute cover 13 is provided on the side wall or top wall of the inner cover 16, and a return air duct is provided in the upper shell body 1. One end of the return air duct is connected to the return air port 167, and the other end is connected to the inlet end 131 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.

[0047] It should be noted that an exhaust port 15 connected to the first air outlet 163 is provided on the upper shell 1 or the lower shell 2. The excess heat inside the pot body assembly 22 is discharged through the first air outlet 163 and 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.

[0048] In this embodiment, the exhaust port 15 is arranged at the top of the upper shell 1, and the exhaust port 15 is communicated with the inner cavity 161. The inner cover 16 is provided with a first air outlet 163 facing 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 163 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, improving the heating efficiency and the heating uniformity of the food.

[0049] 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.

[0050] Embodiment 2:

[0051] The difference between this embodiment and embodiment 1 is that: Figure 4 and Figure 5 As shown, an air induced draft hood 14 is also provided in the upper shell body 1, and the longitudinal section of the air induced draft hood 14 is inverted U-shaped. The air induced draft hood 14 is provided on the heating hood 12, and the bottom end of the air induced draft hood 14 is connected to the connecting portion 125. A cold air cavity 141 is formed between the air induced draft hood 14 and the upper shell body 1, and the cold air cavity 141 is communicated with the outside, and the motor and the volute cover 13 are both located in the cold air cavity 141, so that the cold air from the outside can enter the cold air cavity 141, dissipate heat for the motor in time, and reduce the ambient temperature of the motor, thereby reducing the failure rate of the motor and increasing the service life of the motor; an installation port 142 corresponding to the second air inlet 123 is provided on the side wall of the air induced draft hood 14, 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, so that the wind generated by the fan blade 111 can enter the heating hood 12.

[0052] 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.

[0053] In a feasible embodiment, 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 air induced hood 14, so as to improve the overall thermal insulation performance and prevent the heat in the pot body assembly 22 and the inner cavity 161 from being directly transferred to the upper shell 1, thereby slowing down the temperature rise of the upper shell 1.

[0054] In another possible embodiment, combining Figure 6 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.

[0055] 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.

[0056] 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.

[0057] Combination Figure 7An 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.

[0058] 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.

[0059] Embodiment 3:

[0060] The difference between this embodiment and the above embodiment lies in 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 induced draft cover 14, and an exhaust duct 166 is arranged between the induced draft cover 14 and the top of the upper shell 1, one end of the exhaust duct 166 is connected with the exhaust port 15, and the other end passes through the induced draft cover 14 and the inner cover 16 to be connected with 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.

[0061] Embodiment 4:

[0062] 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.

[0063] Combination Figure 8 When the inner cover 16 is arranged in a ring shape, the exhaust port 15 can be arranged at a position of the upper shell 1 corresponding to the inner cavity 161 and communicated with the inner cavity 161 , and 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 .

[0064] In other embodiments, in combination Fig. 9 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.

[0065] When the inner cover 16 is a cover body with an inverted U-shape in longitudinal section, a first air outlet 163 is provided on the top surface or side wall of the inner cover 16, and the first air outlet 163 is provided above the induced draft hood 14, and 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.

[0066] Embodiment 5:

The wind generated by the fan blades 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 action of the fan blades 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 blades 111, thereby realizing the recycling of the hot air.

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.

[0070] The difference between this embodiment and the above embodiment is that: Fig.10A 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 cold air cavity 141, and is connected to the air inlet area 133 of the volute cover 13.

[0071] When the fan blade 111 rotates, the 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 flows to the volute cover 13, and enters the heating chamber 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 assembly 22 through the air guide 122, so as to heat the food in the pot assembly 22. The external cold air enters from the first air inlet at the bottom of the lower shell 2, and moves upward through the interlayer space 24 between the inner pot 21 and the lower shell 2, thereby improving the cooling effect on the lower shell 2; at the same time, the cold air in the interlayer space 24 takes away the heat of the inner pot 21 and the lower shell 2 and will initially heat up, and can be quickly heated after passing through the heating element 112, shortening the heating time.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] Embodiment 7:

[0078] 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.

[0079] 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.

[0080] Embodiment 8:

[0081] The difference between this embodiment and the above embodiment is that: Fig.11A windshield 168 is provided at the first opening 162 of the inner cover 16, and a second air outlet is provided on the windshield 168. The second air outlet is evenly distributed on the periphery of the windshield 168. The hot air inside the pot body assembly 22 flows into the inner cavity 161 through the second air outlet under the back suction action of the fan blade 111, so that the flow of the hot air is more regular, further improving the recovery rate of the hot air and improving the cooking efficiency of food.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
