[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0032] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0033] like Figure 2 As shown, one embodiment of the present invention provides a cooking pot 1000, comprising a pot body 1100, multiple cooking plates 1200, and a temperature sensor. The sidewalls of pot body 1100 define a cooking cavity 1101, within which multiple cooking plates 1200 are detachably mounted. A first heater 111 is disposed beneath pot body 1100, and a connector electrically connected to first heater 111 is disposed within pot body 1100. First heater 111 is mounted on the bottom of first cooking plate 11, heating the first cooking plate 11 for frying or grilling. A circulating air duct 1102 is also constructed within the sidewalls of pot body 1100, within which a second heater 300 is disposed to generate hot air. The air outlet 1121 and the air inlet 1122 of the circulating air duct 1102 are both connected to the cooking cavity 1101 and deviate from each other, so that hot air circulates in the circulating air duct 1102 and the cooking cavity 1101 for air frying.

[0034] Specifically, the cooking plate 1200 is used to hold food for easy cooking. The offset between the air inlet 1122 and the air outlet 1121 of the circulating air duct 1102 effectively increases the hot air's flow path within the cooking chamber 1101, ensuring maximum contact with the food for air frying. The alternate operation of the first heater 111 and the second heater 300 allows the cooking pot 1000 to have different modes of use. For example, when the first heater 111 is active, the cooking pot 1000 is in grilling mode, while when the second heater 300 is active, the cooking pot 1000 is in air frying mode. A temperature sensor monitors the temperature within the cooking chamber 1101 and provides feedback to the control center of the cooking pot 1000 to regulate the heating temperature of either the first heater 111 or the second heater 300. When the first heater 111 is active, the second heater 300 is inactive. In this state, the heat generated by the first heater 111 is transferred to the first cooking plate 11, grilling the food. In other words, the cooking pot 1000 is in grilling mode. When the second heater 300 is operating, the first heater 111 is not operating. At this time, the heat generated by the second heater 300 is transferred to the airflow within the circulating air duct 1102, heating the airflow to form hot air. The hot air circulates within the circulating air duct 1102 and the cooking cavity 1101, thereby acting on the food within the cooking cavity 1101 and air-frying the food. In other words, the cooking pot 1000 provided in this embodiment is in air-frying mode. In other words, by selectively using one of the two heaters, the cooking pot 1000 has different usage modes, thereby increasing the functionality of the cooking pot 1000, improving its flexibility, and meeting user requirements.

[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, in some embodiments, a pot 1100 includes a main body 100 and a lid 200 that is buckled onto the main body 100. A cooking cavity 1101 is formed between the main body 100 and the lid 200, and a cooking plate 1200 is installed within the main body 100. The main body 100 is configured with a first air duct 1001 that communicates with the cooking cavity 1101, and the fan 15 is installed in the first air duct 1001. The lid 200 is configured with a second air duct 2001 that communicates with the cooking cavity 1101, and the second heater 300 is installed in the second air duct 2001. The second air duct 2001 communicates with the first air duct 1001 to form a circulating air duct 1102, and an air guide filter 104 is provided at the junction of the first and second air ducts 1001 and 2001. Specifically, when the cover 200 is fastened to the main body 100, a sealed cooking cavity 1101 is formed. The first and second air ducts 1001 and 2001 are connected to form a sealed circulation duct 1102. The cooking cavity 1101 is part of the circulation duct 1102, thereby enabling air frying through the circulation of hot air. The air inlet of the first air duct 1001 serves as the air inlet 1122 of the circulation duct 1102, and the air outlet of the second air duct 2001 serves as the air outlet 1121 of the circulation duct 1102. The motive airflow generated by the fan 15 flows through the first air duct 1001 to the second air duct 2001. After being heated by the second heater 300, it flows out along the second air duct 2001 into the cooking cavity 1101, and then flows back to the first air duct 1001 through the cooking cavity 1101, achieving internal circulation heating. The air guide filter 104 is provided to filter the airflow. In a specific embodiment, a control panel is further provided on the main body 100 to facilitate manual control of the cooking pot 1000 to switch between the air frying state and the frying and grilling state.

[0036] like Figure 2 and Figure 6 As shown, in some embodiments, the air outlet 1121 of the circulating air duct 1102 is located at the top of the cooking cavity 1101, and the air inlet 1122 of the circulating air duct 1102 is located on the sidewall of the cooking cavity 1101. Hot air flows from top to bottom into the air inlet 1122 of the circulating air duct 1102. The placement of the air outlet 1121 at the top allows hot air to flow downward from the top of the cooking cavity 1101, effectively affecting the food in the cooking plate 1200 and improving heating uniformity, thereby enhancing the quality of air frying. Furthermore, the placement of the air inlet 1122 on the sidewall of the cooking cavity 1101 allows it to be offset from the air outlet 1121 of the circulating air duct 1102, thereby extending the hot air's flow path within the cooking cavity 1101. In one specific embodiment, the air inlet 1122 of the circulating air duct 1102 has a smaller flow area than the air outlet 1121 of the circulating air duct 1102. Such a setting allows more hot air to stay in the cooking cavity 1101 for a certain period of time, so as to fully contact the food and improve the quality of air frying.

[0037] like Figure 2 and Figure 7 As shown, in some embodiments, the air outlet 1121 is provided with multiple spaced-apart first air holes 401, each of which has a gradually expanding structure from top to bottom. In other words, the multiple spaced-apart first air holes 401 collectively form the air outlet 1121. This structure of first air holes 401 not only ensures airflow but also increases the cross-sectional area of ​​the airflow, dispersing the airflow. This ensures that the hot air flowing out of the air outlet 1121 is evenly applied to the food, improving the quality of the air frying. In one specific embodiment, the multiple first air holes 401 are arranged in a rectangular matrix. This arrangement ensures uniform airflow at the outlet through the regular arrangement of the first air holes 401. In other embodiments, the multiple first air holes 401 are arranged in a circular array. In yet another specific embodiment, the area of ​​the air outlet 1121 accounts for 70%-80% of the horizontal cross-sectional area of ​​the cooking cavity 1101. This arrangement allows the air outlet 1121 of the circulating air duct 1102 to have a larger contact area with the cooking cavity 1101, allowing the hot air in the circulating air duct 1102 to fully contact the food in the cooking cavity 1101. Furthermore, this arrangement ensures that the hot air flowing out of the air outlet 1121 can directly impact the food in a vertical direction, rather than flowing to the sides, thereby improving the utilization rate of the hot air.

[0038] like Figure 2As shown, in some embodiments, the air inlet 1122 is located on the side of the cooking cavity 1101 facing the second heater 300, and the air inlet 1122 includes a plurality of second air holes 402 arranged at intervals, and each second air hole 402 has a tapering structure along the side facing the circulating air duct 1102. The maximum aperture of each second air hole 402 ranges from 2 mm to 3.5 mm. Specifically, the position of the air inlet 1122 relative to the second heater 300 shortens the time it takes for air to flow from the cooking cavity 1101 to the second heater 300, thereby meeting the requirement of rapid heating and improving the efficiency of air frying. At the same time, the provision of multiple second air holes 402 at the air inlet 1122 not only meets the air flow requirements but also disperses the air flow. The coordinated use of the first air hole 401 and the second air hole 402 ensures that the hot air can flow more evenly and stably. The tapered structure of the second air holes 402 accelerates the flow of hot air from the cooking chamber 1101 to the circulating air duct 1102 through the second air holes 402, allowing the hot air to flow more quickly to the circulating air duct 1102 for the next cycle, thereby improving air frying efficiency. Furthermore, the maximum diameter of the second air holes 402 is limited to prevent food in the cooking plate 1200 from leaking through the second air holes 402 into the circulating air duct 1102, thereby isolating food debris and grease. In other embodiments, the minimum diameter of the second air holes 402 ranges from 1.78 mm to 2.65 mm. In one specific embodiment, the maximum diameter of the second air holes 402 ranges from 2 mm, 2.25 mm, 3 mm, 3.5 mm, etc. The minimum diameter of the second air holes 402 ranges from 1.78 mm, 2 mm, 2.36 mm, 2.65 mm, etc.

[0039] like Figure 2 As shown, in some embodiments, the circulating air duct 1102 is constructed with a corner, and the second heater 300 is installed at the corner. Specifically, the circulation of the circulating air duct 1102 within the pot body 1100 means that the circulating air duct 1102 is actually a curved loop to achieve circulation. Therefore, the curved portion of the circulating air duct 1102 is the aforementioned corner. The space at the corner is larger than that at other locations. Therefore, installing the second heater 300 at the corner not only facilitates the assembly of the second heater 300, but also allows the second heater 300 to contact a larger amount of airflow for heat transfer, thereby improving the quality of air frying.

[0040] like Figure 2As shown, in some embodiments, the second heater 300 has a deflector 301 bent along the bending angle of the corner, and the two ends of the deflector 301 along its own bending direction are open. The deflector 301 is detachably connected to the cavity wall of the circulating air duct 1102. The deflector 301 guides the airflow so that the airflow can flow to the heating wire inside the deflector 301 as much as possible for sufficient heating. The deflector 301 is arranged in an arc shape along the bending direction of the corner, which improves the adaptability of the deflector 301 for assembly at the corner. At the same time, the heating wire is assembled inside the deflector 301, and the detachable connection of the deflector 301 relative to the circulating air duct 1102 facilitates the assembly and disassembly of the second heater 300 relative to the circulating air duct 1102.

[0041] like Figure 2 As shown, in some embodiments, a fan 15 is provided within the circulation duct 1102 for accelerating the airflow. Fan 15 comprises a rotating shaft and multiple blades connected to the shaft. Each blade is curved, and the blades form a cylindrical shape. Closing plates are provided at both ends of the shaft along the axis of the fan 15. Specifically, fan 15 is used to provide power to the air within the circulation duct 1102, accelerating the circulation of hot air within the duct 1102, thereby improving air frying efficiency. The motor of fan 15 is activated to drive the shaft, thereby driving the multiple blades to rotate synchronously. The multiple blades are arranged in a cylindrical shape, spaced apart along their own curvature, so that the airflow flows along the curved direction as the shaft rotates, i.e., forming a cylindrical flow. This improves the concentration of the airflow, resulting in greater airflow momentum and lower airflow noise. Furthermore, this arrangement can improve the delivery efficiency of fan 15 and increase the airflow distance. Furthermore, the axial sealing plates at both ends of fan 15 ensure that airflow flows only in a cylindrical shape and along the cylindrical surface, preventing it from flowing outward from the sides. The air inlet 1122 of the circulating air duct 1102 is connected to the air inlet end of fan 15, allowing airflow exiting the cooking chamber 1101 to flow directly toward fan 15 and enter circulation. It can be understood that the configuration of fan 15 in this embodiment achieves low-noise airflow and high power delivery.

[0042] like Figure 2As shown, in some embodiments, a rib plate 172 is provided on one side of the air outlet end of the fan 15 on the circulating air duct 1102, and the rib plate 172 isolates the air inlet end of the fan 15 from the air outlet end of the fan 15. Thus, the rib plate 172 guides the airflow direction, ensuring that the airflow at the air inlet end of the fan 15 must be guided to the air outlet end of the fan 15 as the fan blades rotate, rather than a mixed flow of the air inlet end and the air outlet end. In a specific embodiment, the rib plate 172 extends in a direction close to the rotating shaft, and the extended end of the rib plate 172 can abut against the side wall of the sealing plate to improve the isolation effect. In other embodiments, there is a small gap between the extended end of the rib plate 172 and the sealing plate, and the size of the small gap is 0.5mm-1mm. For example, the size of the small gap is 0.5mm, 0.68mm, 1mm, etc.

[0043] like Figure 2 and Figure 3 As shown, in a specific embodiment, multiple cooking plates 1200 include a first cooking plate 11 and a second cooking plate 12 spaced apart and arranged above the first cooking plate 11. An air duct 112 is provided on the sidewall of the first cooking plate 11. The air duct 112 is connected to and offset from an air inlet 1122. Hot air flows through the second cooking plate 12 to the air duct 112, and from there to the air inlet 1122. When the first heater 111 is operating, the first cooking plate 11 is in use; when the second heater 300 is operating, the second cooking plate 12 is in use. Specifically, both the first cooking plate 11 and the second cooking plate 12 are used to hold food. When the first cooking plate 11 is in use (i.e., for grilling), the second cooking plate 12 can be removed. When the second cooking plate 12 is in use (i.e., for air frying), the first cooking plate 11 remains in place, and the second cooking plate 12 is arranged above the first cooking plate 11. During air frying, the second heater 300 operates while the first heater 111 stops. Hot air, blown into the cooking chamber 1101 from the air outlet 1121 of the circulating air duct 1102, flows through the second cooking plate 12 to the first cooking plate 11, and then from the air guide 112 on the side wall of the first cooking plate 11 to the air inlet 1122 of the circulating air duct 1102, achieving air frying. The offset arrangement of the air guide 112 and the air inlet 1122 prolongs the hot air's trajectory, extending the time the hot air remains in contact with the food in the cooking chamber 1101, thereby ensuring high-quality air frying. During grilling, the first heater 111 operates while the second heater 300 stops. Heat generated by the first heater 111 is directly transferred to the bottom of the first cooking plate 11, and then to the food through the first cooking plate 11, achieving grilling. The configuration of two cooking plates 1200 not only allows for switching between the two cooking modes described above, but also maximizes the utilization of the cooking plates 1200 while reducing costs.

[0044] like Figure 2-Figure 4As shown, in some embodiments, the direction of airflow through air guide vents 112 is perpendicular to the direction of airflow through air inlet 1122. This arrangement allows the airflow, after coming into contact with the food, to flow horizontally and longitudinally to the location of air guide vents 112. During this flow, the airflow remains around the second cooking plate 12, still transferring heat to the food. Simultaneously, the airflow flows horizontally from air guide vents 112 through air inlet 1122, improving the smoothness of the airflow.

[0045] like Figure 4 As shown, in some embodiments, the air guide 112 includes multiple through-holes spaced along the length of the first cooking plate 11. The maximum diameter of the through-holes ranges from 1 cm to 3 cm, and the spacing between any adjacent through-holes ranges from 0.6 cm to 1.2 cm. Specifically, the provision of multiple through-holes not only increases the flow velocity but also the amount of air per flow, thereby improving the air circulation rate. Even if some of the through-holes are blocked, the air guide 112 can still guide the airflow, making it easier for the user to use.

[0046] In one specific embodiment, the first cooking plate 11 is configured as a rectangular parallelepiped, with its short side 11001 facing the air inlet 1122. The air guide 112 (or through-hole) is located on the long side 11002 of the first cooking plate 11. The air inlet 1122 of the circulating air duct 1102 is oriented directly toward the sidewall of the rectangular parallelepiped where the short side 11001 is located. This allows airflow to flow from the first cooking plate 11 to the air inlet 1122 of the circulating air duct 1102 from only one side. This arrangement increases the airflow's contact time around the second cooking plate 12, thereby transferring more heat to the second cooking plate 12 and the food. In other embodiments, multiple, evenly spaced through-holes are provided on both long sides 11002. This arrangement increases the airflow area, increases the flow rate, and thus improves circulation efficiency. In other embodiments, a plurality of evenly spaced through holes are provided along both the long side 11002 and the short side 11001 of the first cooking plate 11. The number of through holes is selected based on the size of the first cooking plate 11. In another specific embodiment, each through hole is rectangular, with a length between 1 cm and 3 cm, a width between 0.5 cm and 1.5 cm, and a spacing between any two adjacent through holes between 0.6 cm and 1.2 cm. For example, the length may be 1 cm, 1.5 cm, or 3 cm, the width may be 0.5 cm, 1 cm, or 1.5 cm, and the spacing may be 0.6 cm, 0.9 cm, or 1.2 cm.

[0047] like Figure 3 and Figure 5As shown, in some embodiments, the bottom of the second cooking plate 12 is constructed with a central hole 121 extending through its thickness. Central hole 121 communicates with the air guide 112, and multiple heightening ribs 123 are scattered around central hole 121. Specifically, the second cooking plate 12 comprises a plate-shaped body that fits snugly with the first cooking plate 11. The plate-shaped body is provided with an oil flow hole 124. To allow oil and water to drain through the oil flow hole 124 and prevent accumulation on the plate-shaped body, the plate-shaped body is designed with a low center and high outer edges. Several heightening ribs 123 are protruded at intervals on the upper end surface of the plate-shaped body, forming a support surface for placing food. A guide channel for hot air is formed between adjacent heightening ribs 123. In this embodiment, the heightening ribs 123 are elongated and arranged radially from the center of the plate-shaped body toward the outer edges, with the central hole 121 located at the center. The above-mentioned guide channel for hot air to flow from the outer edge to the middle of the plate-like body is formed between two adjacent heightening ribs 123. In order to improve the hot air circulation efficiency, each heightening rib 123 is bent in a clockwise or counterclockwise direction. In a specific embodiment, these heightening ribs 123 may also be different. Figure 5 As shown, the dimensions of the heightening ribs 123 indicated by arrow A differ from those of the heightening ribs 123 indicated by arrow B. In alternative embodiments, the heights of these heightening ribs 123 may also differ. This difference in dimensions can be used to adjust the size of the airflow channel, ensuring more effective airflow contact with the food. Furthermore, to facilitate handling of the baking tray, a first flange 122 is provided on the upper end surface of the plate-like body. Two first flanges 122 are provided, located on the left and right sides of the plate-like body; these first flanges 122 can be hooked onto the pot body 1100.

[0048] In summary, in the cooking pot 1000 provided in this embodiment, the circulating air duct 1102 inside the pot body 1100, the cooking cavity 1101, the central hole 121 on the second cooking plate 12, and the air guide port 112 on the first cooking plate 11 together form a closed internal circulation channel, such as Figure 2 The hot air in the entire inner circulation channel is ensured not to come into contact with the airflow in the external environment of the cooking pot 1000, thereby reducing heat loss and improving the quality of air frying.

[0049] like Figure 2 and Figure 4As shown, in some embodiments, the first heater 111 is a heating tube mounted on the bottom of the first cooking plate 11. This arrangement ensures that the heat generated by the heating tube is fully transferred to the first cooking plate 11 for frying and grilling the food. Specifically, the first cooking plate 11 is constructed with a concave cavity with an open top. The bottom wall of the cavity is provided with multiple spaced-apart oil collection grooves 115, each of which forms a cooking surface for placing food. When food is placed on the cooking surface, there is a gap between the food and the bottom of the oil collection grooves 115, which facilitates catching any oil that overflows during cooking. An air vent 112 is located near the bottom of the first cooking plate 11. Above the air vent 112, an annular connecting bar 116 is provided to facilitate the bottom of the second cooking plate 12 to connect to the connecting bar 116, thereby limiting the installation position of the second cooking plate 12 relative to the first cooking plate 11. It can be understood that the annular overlapping strip 116 defines the space within the first cooking plate 11 where air flows through the second cooking plate 12. The spacing between the overlapping strip 116 and the top of the air guide 112 is between 5 mm and 8 mm. This allows for easy assembly of the second cooking plate 12 without interfering with the air guide 112's air guide area. The edge of the opening of the first cooking plate 11 is bent outward to form an annular second flange 113, facilitating its overlap with the pot body 1100. Furthermore, a bent plate extends upward from the opening of the first cooking plate 11, forming a handle 114. Handles 114 are provided on each of the two wide sides of the first cooking plate 11, offset from each other. The provision of the handles 114 facilitates gripping by the user, enhancing ease of installation and removal of the first cooking plate 11 from the pot body 1100.

[0050] The specific structure of the main body 100 is described in detail below.

[0051] like Figure 2-Figure 6As shown, in some embodiments, the main body 100 includes an inner shell 13 for accommodating a first cooking plate 11. The air inlet 1122 of the circulation duct 1102 is disposed on the sidewall of the inner shell 13. When the first cooking plate 11 is installed in the inner shell 13, the second flange 113 of the first cooking plate 11 overlaps the edge of the inner shell 13, and a gap 101 is defined between the first cooking plate 11 and the inner shell 13. This gap 101 communicates with both the air guide 112 of the first cooking plate 11 and the air inlet 1122 of the circulation duct 1102. In one specific embodiment, the area of ​​the air inlet 1122 of the circulation duct 1102 accounts for 70%-80% of the area of ​​the sidewall of the inner shell 13. This arrangement guides the airflow, ensuring that airflow is maintained while preventing it from escaping from the sides, thereby improving airflow accuracy. In another specific embodiment, a plurality of second air holes 402 are arranged in a dense rectangular array on the sidewall of the inner shell 13. In another specific embodiment, a rectangular opening can be provided on the side wall of the inner shell 13, and a wind screen can be embedded in the rectangular opening, forming an air inlet 1122 of the circulating air duct 1102. Furthermore, a power port for connecting the first heater 111 is configured at the bottom of the inner shell 13. The connector on the first heater 111 can pass through the power port and plug into the connector on the main body 100, thereby facilitating circuit conduction.

[0052] like Figure 6 As shown, in some embodiments, the main body 100 further includes an outer shell 14 positioned over the outer shell 13, with an installation space 103 formed between the outer shell 14 and the inner shell 13. This installation space 103 not only accommodates the installation position of the fan 15 but also forms a first air duct 1001. In one specific embodiment, a mounting bracket 16 is further disposed between the inner shell 13 and the outer shell 14, securing the inner shell 13 to the outer shell 14. An extension platform 17 is disposed on the side of the inner shell 13 facing the installation space 103. The extension platform 17 defines a through-hole 171 that connects the first air duct 1001 and the second air duct 2001. A rib 172 is disposed at the through-hole 171. A curved shell 18 is disposed at the bottom of the extension platform 17, thereby defining the installation space 103 together with the extension platform 17 and the curved shell 18. A mounting plate 19 with a notch is disposed on the side of the extension platform 17 facing the cover 200, and the aforementioned air guide filter 104 is embedded in the notch.

[0053] like Figure 2 and Figure 6As shown, in some embodiments, the area of ​​the air inlet of the first air duct 1001 is larger than the area of ​​the air outlet of the first air duct 1001. According to the foregoing, the air inlet of the first air duct 1001 is actually connected to the air inlet of the fan 15, and the air outlet of the first air duct 1001 is connected to the air outlet of the fan 15. Therefore, such a setting can meet the normal working effect of the fan 15, so as to inhale more airflow. Moreover, it is precisely because of the above-mentioned area difference that the airflow sent out by the fan 15 is a high-pressure airflow. In this way, when in the air frying mode, it is ensured that the airflow acting on the food is a high-temperature, high-speed, and high-pressure airflow, thereby improving the cooking effect. For example, the area of ​​the air inlet of the first air duct 1001 is 5885.4mm 2 The area of ​​the air outlet of the first air duct 1001 is 3607.92mm 2 .

[0054] The specific structure of the cover 200 is described in detail below.

[0055] like Figure 2 and Figure 7 As shown, in some embodiments, the cover body 200 includes an inner cover 21 and a cover shell 22 connected to the inner cover 21. The inner cover 21 is configured with an opening 211 on the side facing the main body 100. The cover shell 22 is configured to enclose a second air duct 2001. The air outlet 1121 of the circulation air duct 1102 is provided on the side of the cover shell 22 facing the opening 211, and the second heater 300 is installed within the cover shell 22. The corner of the circulation air duct 1102 is provided within the cover shell 22, specifically near the top corner of the cover body 200. The provision of the cover shell 22 defines the second air duct 2001, thereby improving the airtightness of the second air duct 2001 and meeting the internal circulation requirements of the circulation air duct 1102.

[0056] like Figure 2 、 Figure 7 and Figure 8As shown, in one specific embodiment, the housing 22 includes a bottom housing 221 and a top housing 222 that is buckled onto the bottom housing 221. The air outlet 1121 of the circulating air duct 1102 is located on the bottom housing 221, and the second air duct 2001 is located between the top housing 222 and the bottom housing 221. A flow cavity 2212 with an open top and bottom is formed on the end of the bottom housing 221 that faces the installation space 103. The flow cavity 2212 communicates with the installation space 103 through the bottom opening, and the second heater 300 is located in the top opening. The provision of the flow cavity 2212 connects the housing cavity of the top housing 222 with the installation space 103 on the main body 100 and guides the flow of air. Therefore, in this embodiment, the flow cavity 2212 and the housing cavity together define the second air duct 2001. In some specific embodiments, a snap-fit ​​structure is provided on the wall of the flow cavity 2212 to facilitate snap-fitting and securing with the second heater 300. At the same time, the cover body 200 further includes an outer cover 23 that is arranged on the outside of the cover shell 22 and the inner cover 21 , thereby integrating the cover shell 22 and the inner cover 21 to form a complete cover body 200 .

[0057] It should be added that the cover 200 and the main body 100 can be connected in a hinged manner to facilitate the opening and closing of the cover 200 relative to the main body 100. In a specific embodiment, the cover 200 has a first pressing surface 2002, and the main body 100 has a second pressing surface 1002. The first pressing surface 2002 and the second pressing surface 1002 are respectively provided with magnetic elements, and the first pressing surface 2002 and the second pressing surface 1002 are pressed and matched by the magnetic elements. In other words, on the basis of the hinged connection between the cover 200 and the main body 100, the two are fastened by magnetic elements. The cooperation between the first pressing surface 2002 and the second pressing surface 1002 improves the sealing performance of the connection between the cover 200 and the main body 100. Among them, a flip handle 201 is provided on the cover 200. At the same time, a viewing window 202 is provided on the cover 200 to facilitate the user to observe the food in the pot through the viewing window 202.
