Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of small household appliances, in particular to a cooking appliance. BACKGROUND

[0002] In the related art, the cooking appliance has the functions of air frying and steaming. The structure for realizing the air frying function includes a fan and a heating element. The fan blows air to the heating element, and the heated air is blown into the cooking cavity of the cooking appliance through the heating element. The structure for realizing the steaming function includes a water tank and a steam generator in communication with the water tank. The steam generated by the steam generator is sprayed into the cooking cavity of the cooking appliance.

[0003] However, in the process of realizing the steaming function, steam is easy to enter the heating element, which can easily damage the heating element. SUMMARY

[0004] The main purpose of the present application is to provide a cooking appliance to solve the problem of easy damage of the heating element in the related art.

[0005] In order to achieve the above-mentioned purpose, the present application provides a cooking appliance, which comprises a pot body, a pan body arranged in the pot body, a cover body arranged on the pan body, a hot air generating device arranged in the pot body, the hot air generating device having a fan and a hot air outlet, and a heating device arranged on the pot body or the pan body. The first air guide cover is arranged below the cover body and can be horizontally rotated. The first air guide cover has a guide position in communication with the hot air outlet and a shielding position shielding the hot air outlet.

[0006] The technical scheme of the present application is applied to the cooking appliance, which has a baking mode and a steaming mode. When the user needs to use the baking mode, the user horizontally rotates the first air guide cover so that the first air guide cover is located at the guide position in communication with the hot air outlet. Then, the baking mode is started, the hot air generating device works, the fan inhales air, the hot air is blown out through the hot air outlet, the hot air enters the first air guide cover and then enters the pan body, and the food in the pan body is heated. When the user needs to use the steaming mode, the user horizontally rotates the first air guide cover so that the first air guide cover is located at the shielding position shielding the hot air outlet, and then the steaming mode is started. The heating device works, the pan body is heated and steam is generated in the pan body. At this time, since the first air guide cover shields the hot air outlet, the steam cannot enter the hot air outlet, and thus the steam cannot enter the hot air generating device, avoiding damage caused by the entry of steam into the hot air generating device. Therefore, the technical scheme of the present application effectively solves the problem of easy damage of the heating element in the related art.

[0007] Furthermore, the first air guide hood includes a hood body, an air guide port provided at a first end of the hood body, and a shielding plate provided at a second end of the hood body. In the above structure, when the first air guide hood is in the air guiding position, the air guide port is connected with the hot air outlet, and then the hot air outlet is connected with the interior of the pot body. When the hot air generating device is working, the hot air blown out from the hot air outlet flows along the interior of the hood body and then enters into the pot body, and the hood body plays an air guiding role. When the first air guide hood is in the shielding position, the shielding plate blocks the hot air outlet, isolating the hot air outlet from the pot body. When the pot body is heated and steam is generated therein, the steam flows to the shielding plate near the hot air outlet, and the steam cannot pass through the shielding plate into the hot air outlet. The shielding plate can effectively block the steam.

[0008] Furthermore, the shielding plate is a curved plate; and / or the first air guide cover further includes an inclined air guide surface disposed within the cover body. In the above structure, the curved plate can increase the shielding area of ​​the shielding plate compared to a flat plate, completely blocking the entire hot air outlet and improving the shielding effect. When the first air guide cover is in the air guiding position, the hot air blown out from the hot air outlet, as it passes through the interior of the cover body, can be blown directly into the pot body along the inclined air guide surface, thus achieving a good air guiding effect.

[0009] Furthermore, the cooking appliance further includes an adjustment structure connecting the first air scoop and the cover, the adjustment structure including an adjustment shaft that passes through the first air scoop and is connected to the cover, and the first air scoop is rotatably arranged around the adjustment shaft. In the above structure, the first air scoop can be adjusted on the cover by the adjustment structure to enable the first air scoop to switch between an air-guiding position and a shielding position. The provision of the adjustment shaft can form a rotation center of the first air scoop, thereby facilitating improved rotational stability of the first air scoop. At the same time, the first air scoop can move along the adjustment shaft and then rotate around the adjustment shaft.

[0010] Furthermore, the adjustment structure also includes an elastic member sleeved outside the adjustment shaft, the adjustment shaft includes a stop portion, the elastic member is located between the stop portion and the first air guide cover, and the elastic member applies an elastic force toward the cover body to the first air guide cover; and / or the cover body includes a face cover, the first air guide cover is arranged below the face cover, and the distance that the first air guide cover moves along the axis of the adjustment shaft is greater than the height of the face cover. In the above structure, the elastic member is always in a compressed state, so regardless of whether the first air guide cover is in the wind-guiding position or the shielding position, the elastic member can apply an elastic force toward the cover body to the first air guide cover, so that the first air guide cover abuts against the lower surface of the cover body. And the elastic member is always in a compressed state, so regardless of whether the first air guide cover is in the wind-guiding position or the shielding position, the elastic member can apply an elastic force toward the cover body to the first air guide cover, so that the first air guide cover abuts against the lower surface of the cover body.

[0011] Further, the first air deflector comprises a cover body and a matching cylinder arranged on the cover body, the matching cylinder is sleeved outside the adjusting shaft, an inner flange is arranged at an end of the matching cylinder away from the stopper, and the two ends of the elastic member are respectively abutted on the inner flange and the stopper. In the above structure, during the process that the first air deflector is switched from the air guiding position to the shielding position, because the two ends of the elastic member are respectively abutted on the inner flange and the stopper, the inner flange and the stopper limit the two ends of the elastic member respectively under the condition that the elastic member is extruded by the first air deflector, so that the elastic member is compressed and deformed, and the cover body moves along the axis of the adjusting shaft in the direction away from the cover. Under the condition that the external force applied on the elastic member disappears, the stopper stops one end of the elastic member, so that the other end of the elastic member applies the elastic force towards the cover to the inner flange, the elastic member is elastically reset by overcoming the gravity of the first air deflector, and the cover body moves along the axis of the adjusting shaft in the direction towards the cover. Correspondingly, the process that the first air deflector is switched from the shielding position to the air guiding position is the reverse process of the above process, which will not be described here.

[0012] Further, in order to quickly and stably position the first air deflector in the air guiding position or the shielding position, the cooking appliance further comprises a positioning structure arranged between the first air deflector and the cover.

[0013] Further, the positioning structure comprises a first positioning hole, a second positioning hole and a first positioning column matched with the first positioning hole and the second positioning hole, one of the cover and the first air deflector is provided with the first positioning hole and the second positioning hole, and the other of the cover and the first air deflector is provided with the first positioning column, the first positioning column is switched between the first positioning hole and the second positioning hole, so that the first air deflector is switched between the air guiding position and the shielding position. In the above structure, the first positioning column is matched with the first positioning hole and the second positioning hole, so that the first air deflector is easily switched between the air guiding position and the shielding position, and the positioning effect is good.

[0014] Further, the first positioning hole and the second positioning hole are symmetrically arranged with respect to the rotation axis of the first air deflector; and / or, the positioning structure further comprises a second positioning column matched with the first positioning hole and the second positioning hole. In the above structure, the first air deflector is switched from the air guiding position to the shielding position by rotating around the adjusting shaft. Similarly, the first air deflector is switched from the shielding position to the air guiding position by rotating around the adjusting shaft.

[0015] Furthermore, the lid body includes a cover and a handle structure disposed above the cover, a first air guide hood disposed below the cover, and the cooking appliance further includes an adjustment structure connecting the first air guide hood and the lid body, the adjustment structure passing through the first air guide hood and the cover and connected to the handle structure; and / or, a relief notch is disposed at a position on the cover corresponding to the hot air outlet, wherein when the first air guide hood is in the air guiding position, the air guide port communicates with the relief notch, and when the first air guide hood is in the shielding position, the shielding plate shields the relief notch. The above structure can reduce the amount of steam leaking from the relief notch.

[0016] Furthermore, the hot air generating device includes: an air duct structure disposed within the pot body, a fan disposed within the air duct structure; a heating device, the heating device including a housing, a heating element disposed within the housing, and a second air guide disposed on one side of the housing, the housing being in communication with the air duct structure, and a hot air outlet disposed on the second air guide; wherein, when the first air guide is in the air guiding position, the first air guide is mounted on the outer wall of the second air guide. In the above structure, hot air blown out from the hot air outlet enters the pot body directly along the inner cavity of the second air guide. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0040] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0041] like FIGS. 1-5 and FIG. 16 As shown, the cooking appliance of this embodiment includes: a pot body 10, a pot body 20, a lid body 30, a hot air generating device, a heating device 60, and a first air guide 70. The pot body 20 is mounted on the pot body 10. The lid body 30 covers the pot body 20. The hot air generating device is mounted on the pot body 10 and includes a fan 43 and a hot air outlet 51. The heating device 60 is mounted on the pot body 20. The first air guide 70 is horizontally rotatably disposed below the lid body 30. The first air guide 70 has an air guiding position that connects to the hot air outlet 51 and a blocking position that blocks the hot air outlet 51.

[0042] Using the technical solution of this embodiment, the cooking appliance has a baking mode and a steaming mode. When the user desires to use the baking mode, the user rotates the first air guide 70 horizontally so that it is in an air guiding position connected to the hot air outlet 51. The baking mode is then activated, the hot air generating device operates, the fan 43 draws in air, and blows hot air through the hot air outlet 51. The hot air enters the first air guide 70 and then enters the pot body 20, heating the food therein. When the user desires to use the steaming mode, the user rotates the first air guide 70 horizontally so that it is in a blocking position, shielding the hot air outlet 51. The steaming mode is then activated, the heating device 60 operates, and the pot body 20 is heated to generate steam. Since the first air guide 70 blocks the hot air outlet 51, steam cannot enter the hot air outlet 51, and thus cannot enter the hot air generating device, thus preventing steam from entering the hot air generating device and causing damage. Therefore, the technical solution of this embodiment effectively solves the problem of easy damage of the heating element in the related art.

[0043] Of course, in an embodiment not shown in the figures, the heating device can be arranged on the pot body.

[0044] likeFIG. 3 and FIG. 5 As shown, the first air guide 70 is horizontally rotatable below the lid 30 to switch between an air-guiding position and a blocking position. This rotational design facilitates user operation, saving time and effort. It should be noted that the aforementioned "horizontal rotation" means that when the lid 30 is covering the pot 20, the rotation axis of the first air guide 70 is perpendicular to the bottom surface of the cooking appliance.

[0045] In this embodiment, the hot air generating device and the heating device realize different cooking modes. Specifically, the heating device realizes heating the bottom of the pot body, thereby generating steam to realize the cooking mode, and the hot air generating device is arranged on the side of the pot body, heating the air and generating hot air to realize the baking mode.

[0046] like FIG. 3 、 FIGS. 5-7 As shown, the first air guide hood 70 includes a hood body 71, an air guide port 75 disposed at a first end of the hood body 71, and a shielding plate 76 disposed at a second end of the hood body 71. Thus, when the first air guide hood 70 is in the air guiding position, the air guide port 75 communicates with the hot air outlet 51, and the hot air outlet 51 then communicates with the interior of the pot body 20. When the hot air generating device is operating, the hot air blown out of the hot air outlet 51 flows along the interior of the hood body 71 and then enters the pot body 20, with the hood body 71 acting as an air guide. When the first air guide hood 70 is in the shielding position, the shielding plate 76 blocks the hot air outlet 51, isolating the hot air outlet 51 from the pot body 20. When the pot body 20 is heated and steam is generated therein, the steam flows to the vicinity of the hot air outlet 51 and is blocked by the shielding plate 76. The steam cannot pass through the shielding plate 76 and enter the hot air outlet 51, and the shielding plate 76 can effectively block the steam.

[0047] like FIG. 3 、 FIGS. 5-7 As shown, the shielding plate 76 is a curved plate. The first air guide cover 70 also includes an air guide slope 77 arranged in the cover body 71. Compared with a flat plate, the curved plate can increase the shielding area of ​​the shielding plate 76, completely shield the entire hot air outlet 51, and improve the shielding effect. When the first air guide cover 70 is in the air guiding position, the hot air blown out from the hot air outlet 51 can be blown directly into the pot body 20 along the air guide slope 77 when passing through the inside of the cover body 71, and the air guiding effect is good. Of course, the shielding plate can also be a flat plate or a corrugated plate. The above-mentioned air guide slope can be a plane or a curved surface that is convenient for air guiding.

[0048] like FIG. 3 、 FIG. 5 and FIG. 6As shown, the cooking appliance further comprises an adjustment structure 80 connecting the first air guide cover 70 and the cover 30. In this way, the first air guide cover 70 can be adjusted on the cover 30 by the adjustment structure 80 so that the first air guide cover 70 is switched between the air guiding position and the shielding position.

[0049] like FIG. 3 、 FIGS. 5-8 As shown, the adjustment structure 80 includes an adjustment shaft 81, which passes through the first air scoop 70 and is connected to the cover body 30. In this embodiment, the adjustment shaft 81 extends in a vertical direction. The first air scoop 70 is rotatably arranged around the adjustment shaft 81. The arrangement of the adjustment shaft 81 can form the rotation center of the first air scoop 70, thereby improving the rotational stability of the first air scoop 70. At the same time, the first air scoop 70 can move along the adjustment shaft 81.

[0050] like FIG. 3 、 FIGS. 5-8 As shown, the adjustment structure 80 further includes an elastic member 82 sleeved over the adjustment shaft 81. The adjustment shaft 81 includes a stopper 813. The elastic member 82 is positioned between the stopper 813 and the first air scoop 70. The elastic member 82 is always in a compressed state. Therefore, regardless of whether the first air scoop 70 is in the air guiding position or the shielding position, the elastic member 82 can exert an elastic force on the first air scoop 70 toward the cover body 30, causing the first air scoop 70 to abut against the lower surface of the cover body 30.

[0051] Specifically, the adjustment shaft 81 of this embodiment includes a smooth rod section 811, a threaded section 812, and a stopper 813. The threaded section 812 and the stopper 813 are respectively located at both ends of the smooth rod section 811. The provision of the smooth rod section 811 can reduce the friction between the adjustment shaft 81 and the first air guide cover 70, reduce the movement resistance, and enable the first air guide cover 70 to move smoothly on the adjustment shaft 81. The provision of the threaded section 812 facilitates the connection of the adjustment shaft 81 to the cover body 30, thereby improving the reliability of the connection. The adjustment structure 80 also includes an elastic member 82 sleeved on the outside of the adjustment shaft 81. The provision of the stopper 813 facilitates the stopping of the elastic member 82, thereby allowing the first air guide cover 70 to be supported by the elastic member 82, preventing the elastic member 82 and the first air guide cover 70 from separating from the adjustment shaft 81. Preferably, the stopper 813 is a stop ring, a stop block, or a stop sheet.

[0052] Of course, the adjustment structure can also be a magnetic structure or a snap-fit ​​structure.

[0053] The switching operation method of the first air guide cover 70 will be introduced below.

[0054] When the first air scoop 70 switches from the air guiding position to the shielding position, the user pulls the first air scoop 70, causing it to move along the axis of the adjustment shaft 81 away from the cover body 30. The elastic member 82 is further compressed by the force applied by the first air scoop 70. The user then rotates the first air scoop 70 180 degrees around the adjustment shaft 81. When the first air scoop 70 is rotated to a position close to the shielding position, the user releases the first air scoop 70, causing the external force applied to the elastic member 82 to disappear. The elastic member 82 applies an elastic force toward the cover body 30 to the first air scoop 70, pushing the first air scoop 70 toward the cover body 30 and ultimately allowing the first air scoop 70 to cling tightly to the cover body 30. At this point, the first air scoop 70 reaches the shielding position. Accordingly, the process of switching the first air scoop 70 from the shielding position to the air guiding position is the reverse process of the above process and will not be described in detail here.

[0055] like FIG. 3 、 FIGS. 5-8 as well as FIG. 17 and FIG. 18 As shown, the cover body 30 includes a face cover 32, and a first air scoop 70 is disposed below the face cover 32. The distance that the first air scoop 70 moves along the axis of the adjustment shaft 81 is greater than the height of the face cover 32. Specifically, the distance that the first air scoop 70 moves along the axis of the adjustment shaft 81 in a direction away from the cover body 30 is greater than the height of the face cover 32, so that the projections of the first air scoop 70 and the face cover 32 on a vertical plane do not completely overlap, thereby avoiding interference.

[0056] like FIG. 3 、 FIGS. 5-8 as well as FIG. 17 and FIG. 18 As shown, when the first air guide cover 70 switches from the wind guiding position to the shielding position, the first air guide cover 70 moves along the axis of the adjustment shaft 81 in a direction away from the cover body 30. When the upper surface of the first air guide cover 70 is lower than the bottom surface of the face cover 32, the first air guide cover 70 can completely avoid the face cover 32 when rotating, thereby avoiding interference between the first air guide cover 70 and the face cover 32 when rotating. At this time, after the first air guide cover 70 rotates through a certain angle (such as 180 degrees), under the action of the elastic force of the elastic member 82, the first air guide cover 70 can move along the axis of the adjustment shaft 81 to switch to the shielding position. In this way, the first air guide cover 70 can switch from the wind guiding position to the shielding position more smoothly around the adjustment shaft 81. Accordingly, the process of switching the first air guide cover 70 from the shielding position to the wind guiding position is the reverse process of the above process and will not be repeated here.

[0057] like FIG. 3 、 FIGS. 5-8As shown, the first air guide cover 70 includes a cover body 71 and a matching cylinder 72 provided on the cover body 71. The matching cylinder 72 is sleeved on the outside of the adjustment shaft 81. When the first air guide cover 70 switches from the air guiding position to the shielding position, the setting of the matching cylinder 72 prevents the first air guide cover 70 from deflecting relative to the adjustment shaft 81, so that the first air guide cover 70 can move and rotate smoothly along the adjustment shaft 81. An inner flange 73 is provided at one end of the matching cylinder 72 away from the stop portion 813, and the two ends of the elastic member 82 respectively abut against the inner flange 73 and the stop portion 813.

[0058] Specifically, during the process of switching the first air scoop 70 from the air guiding position to the shielding position, because the ends of the elastic member 82 respectively abut against the inner flange 73 and the stopper 813, when the elastic member 82 is squeezed by the first air scoop 70, the inner flange 73 and the stopper 813 respectively restrain the ends of the elastic member 82, causing the elastic member 82 to be compressed and deformed, and the cover body 71 to move away from the cover body 30 along the axis of the adjustment shaft 81. When the external force applied to the elastic member 82 disappears, the stopper 813 stops one end of the elastic member 82, so that the other end of the elastic member 82 applies an elastic force toward the cover body 30 against the inner flange 73. The elastic member 82 overcomes the weight of the first air scoop 70 and elastically returns to its original position, causing the cover body 71 to move toward the cover body 30 along the axis of the adjustment shaft 81. Accordingly, the process of switching the first air scoop 70 from the shielding position to the air guiding position is the reverse of the above process and will not be further described here. The elastic member 82 of this embodiment is preferably a spring. Of course, the elastic member can also be a silicone member, etc.

[0059] like FIG. 3 、 FIGS. 5-8 As shown, in order to quickly and stably position the first air guide cover 70 at the air guide position or the shielding position, the cooking appliance further includes a positioning structure provided between the first air guide cover 70 and the cover body 30 .

[0060] like FIG. 3 、 FIGS. 5-9 As shown, the positioning structure includes a first positioning hole 311, a second positioning hole 312, and a first positioning post 741 that cooperates with the first positioning hole 311 and the second positioning hole 312. The cover body 30 is provided with the first positioning hole 311 and the second positioning hole 312, and the first air guide cover 70 is provided with the first positioning post 741. The first positioning post 741 switches between the first positioning hole 311 and the second positioning hole 312 to switch the first air guide cover 70 between the air guiding position and the shielding position. The first positioning post 741 cooperates with the first positioning hole 311 and the second positioning hole 312, making it easy to switch the first air guide cover 70 between the air guiding position and the shielding position, and achieving a good positioning effect.

[0061] Of course, in an embodiment not shown in the figures, a first positioning hole and a second positioning hole are provided on the first air guide cover, and a first positioning column is provided on the cover body.

[0062] like FIG. 3 、 FIGS. 5-9 As shown, in order to enable the first air guide cover 70 to be stably positioned at the air guiding position and the shielding position, the positioning structure further includes a second positioning column 742 that cooperates with the first positioning hole 311 and the second positioning hole 312 .

[0063] like FIG. 5 and FIG. 7 As shown, the matching cylinder 72 protrudes from the first positioning column 741 and the second positioning column 742 .

[0064] like FIG. 3 、 FIG. 5 、 FIG. 17 and FIG. 18 As shown, the first positioning hole 311 and the second positioning hole 312 are symmetrically arranged with respect to the rotation axis of the first air scoop 70. Thus, the first air scoop 70 rotates 180 degrees about the adjustment shaft 81 to switch from the air guiding position to the blocking position. Similarly, the first air scoop 70 rotates 180 degrees about the adjustment shaft 81 to switch from the blocking position to the air guiding position.

[0065] like FIGS. 9-12 As shown, the cover 32 includes a cover body 323 and a transparent plate 322 located below the cover body 323. The cover body 323 has a hollow structure. While the cooking appliance is cooking food, the cooking process can be visually observed through the hollow portion and the transparent plate 322. The transparent plate 322 is provided with a first through hole 3221 and a second through hole 3222.

Thus, when the first air guide 70 is in the shielding position, the shielding plate 76 not only blocks the avoidance gap 321 but also partially blocks the gap between the pot body 20 and the cover body 323, reducing steam leakage. The dimensional error between the radius R1, the radius R2, and the radius R3 is within 10%, effectively ensuring the shielding effect of the shielding plate 76.

[0072] like FIG. 7 、 FIG. 13 andFIG. 17 and FIG. 18 As shown, the height H1 of the shielding plate 76 is less than or equal to the height H2 of the avoidance gap 321. In this way, a matching gap is left between the shielding plate 76 and the avoidance gap 321, which facilitates the first air guide cover 70 to switch between the air guiding position and the shielding position.

[0073] like FIG. 2 and FIG. 4 As shown, the hot air generating device includes: an air duct structure 40 and a heating device 50. The air duct structure 40 is arranged in the pot body 10, and the fan 43 is arranged in the air duct structure 40. The heating device 50 includes a shell 54, a heating element 52 arranged in the shell 54, and a second air guide cover 53 arranged on one side of the shell 54. The shell 54 is connected to the air duct structure 40, and the hot air outlet 51 is arranged on the second air guide cover 53. Specifically, when the first air guide cover 70 is in the air guiding position, the first air guide cover 70 is placed on the outer wall of the second air guide cover 53. In this way, the hot air blown out from the hot air outlet 51 directly enters the pot body 20 along the inner cavity of the second air guide cover 53. The air duct structure 40 includes an air inlet 42 and an air outlet 41. The air inlet 42 is located upstream of the fan 43, and the air outlet 41 is located downstream of the fan 43. The heating element 52 is a heating tube or a heating wire.

[0074] It should be noted that the location of the hot air generating device inside the pot body is not limited to the entire hot air generating device being arranged inside the pot body, but also includes the situation where the main structure of the hot air generating device is located inside the pot body and part of the structure extends outside the pot body. In this embodiment, the main structure of the hot air generating device is located inside the pot body and part of the second air guide cover 53 of the partial structure extends outside the pot body.

[0075] In the related art, a heating device is provided on the base of the cooking utensil, and the pot body is placed on the heating device for heating. After the cooking utensil finishes cooking, the pot body is taken out and is in a high temperature state, which can easily scald the user.

[0076] In order to solve the above problems, FIG. 2 and FIG. 4As shown, in this embodiment, the pot body 20 includes an outer shell and a pot body disposed within the outer shell, and the heating device 60 is disposed on the pot body. During the cooking process of the cooking utensil, the heating device 60 adheres to the pot body, and there is no gap between the heating device 60 and the pot body, so that the heating device 60 can directly heat the pot body, which has a good heat conduction effect and the pot body heats up faster. After the cooking utensil has finished cooking, after the pot body 20 is taken out, since the outer shell protects the outside of the pot body, the shell can block the heat radiated outward by the pot body, avoiding direct contact with the user, thereby preventing burns to the user. Specifically, the heating device 60 includes a heating element, which is welded to the bottom of the pot body. In this way, the heating element can be firmly connected to the bottom of the pot body. The heating element is preferably a heating tube, a heating wire, or a heating plate.
