Detailed Implementation

[0031] The embodiments of this application are described in detail below, and examples of these embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0033] An air fryer is a machine that uses air to "fry" food. It uses a high-temperature heating element inside the machine to generate hot air, and then a fan blows the hot air into the fryer to heat the food, causing it to dehydrate and turn golden brown and crispy, achieving the effect of frying.

[0034] In existing air fryers, the heating element 50 is generally located above the cooking cavity, which cannot be extended to steaming or boiling. Some products have heating elements 50 located both above and below the cooking cavity, which can extend to steaming or boiling, but the structure is complex and the cost is high.

[0035] Based on the above issues, please also refer to Figure 1 and Figure 2 This application provides a cooking appliance 1 to solve the above problems. Figure 1 A schematic diagram of the structure of a cooking utensil 1 provided in an embodiment of this application is shown. Figure 2 for Figure 1 A cross-sectional view along line AA shows that the cooking appliance 1 may include: a housing 10, a pot body 20, an upper mechanism 30, a food carrier 40, and a heating element 50.

[0036] The shell 10 forms a receiving space 110. The shell 10 can be a barrel-shaped structure, and the receiving space 110 can be used to house internal components such as the pot body 20, the carrying device 40, and the heating element 50. This application embodiment does not limit the structure or shape of the receiving space 110; it can be specifically designed according to actual conditions. For example, the shell 10 can be made of 304 stainless steel. This stainless steel material has heat resistance, rust prevention, and corrosion resistance, which can protect the internal components of the air fryer from external corrosion. At the same time, the 304 stainless steel shell 10 is also relatively sturdy and not easily deformed or damaged, which helps to improve the service life of the shell 10, and thus the service life of the cooking appliance 1.

[0037] Please also refer to Figure 2 , Figure 3 and Figure 4 The pot body 20 is detachably disposed within the receiving space 110, and can be used to hold ingredients to be cooked. In one embodiment, the pot body 20 may include an inner pot 220 and an outer pot 230. The outer pot 230 is detachably disposed within the receiving space 110, and the inner pot 220 is detachably disposed within the outer pot 230. Ingredients can be placed inside the inner pot 220. Detachable connection between the inner pot 220 and the outer pot 230 facilitates cleaning of the pot body 20. For example, the user can remove only the inner pot 220, which is in contact with the food, for cleaning, without needing to clean the outer pot 230, thus reducing the user's cleaning burden. It is understood that when the cooking appliance 1 has just finished cooking food, the temperature of the inner pot 220 is at a high level; therefore, it can be removed together with the outer pot 230 to prevent the user from being burned.

[0038] In this embodiment, the inner pot 220 can be made of aluminum alloy, which is lightweight, has good thermal conductivity and corrosion resistance, making it easy for users to handle while quickly transferring heat. The outer pot 230 can be made of materials with low thermal conductivity, such as tungsten diselenide, rubber, or ceramics.

[0039] In some embodiments, to facilitate the user's removal of the outer pot 230, a handle 231 may be provided on the edge of the outer pot 230. The user can remove the outer pot 230 by gripping the handle 231. Furthermore, to ensure stability during the removal of the outer pot 230, two handles 231 may be provided, with the two handles positioned opposite each other. This allows the user to grip one handle 231 with each hand, improving stability when removing the outer pot 230. In other embodiments, the pot body 20 may only include the inner pot 220; this embodiment does not limit this.

[0040] Please also refer to Figure 5The upper mechanism 30 can be disposed on the housing 10 and can close the receiving space 110. That is, the cooking appliance 1 provided in this embodiment can have two states: the first state is when the upper mechanism 30 closes the receiving space 110, at which time the cooking appliance 1 can be used to cook food; the second state is when the upper mechanism 30 opens the receiving space 110, at which time the user can put food into the pot body 20 or remove the pot body 20, etc. It should be noted that this embodiment does not limit the specific arrangement and connection method between the upper mechanism 30 and the housing 10. For example, the arrangement method between the upper mechanism 30 and the housing 10 can be a rotating arrangement or a detachable arrangement; the connection method between the upper mechanism 30 and the housing 10 can be a hinge connection or a pivot connection, etc.

[0041] Please also refer to Figure 6 The carrying device 40 can be installed inside the pot body 20, specifically inside the inner pot 220 of the pot body 20. The carrying device 40 can include a bottom plate 410. A first circulation channel 430 is formed between the outer periphery of the bottom plate 410 and the inner wall of the pot body 20 (i.e., the inner wall of the inner pot 220). The first circulation channel 430 connects the upper and lower sides of the carrying device 40. The first circulation channel 430 can provide hot airflow circulation, and heat can be transferred from the bottom of the carrying device 40 to the top of the carrying device 40, thereby heating the food in all directions. In this embodiment, the carrying device 40 also includes a side plate 420, which is connected to the edge of the bottom plate 410. This can prevent food from leaking out and affecting the cooking method and taste of the food. The first circulation channel 430 is also formed between the side plate 420 and the inner wall of the pot body 20. By setting the side plate 420, the guiding effect of the first circulation channel 430 formed between the carrying device 40 and the inner wall of the inner pot 220 can be improved, and the stewing function can also be realized.

[0042] The hot air generated by the heating element 50 after heating can flow into the food carrier 40 through the first circulation channel 430 to cook the food inside the food carrier 40. Specifically, since hot air flows upward in a natural state, the heat generated by the heating element 50 when it is working can flow upward and reach the lower surface of the base plate 410 of the food carrier 40. Due to the obstruction of the base plate 410, the hot air will flow to both sides and then flow into the first circulation channel 430. Then the hot air can continue to flow upward until it reaches the vicinity of the upper core 30. At this time, the fan assembly 60 can blow the hot air downward, that is, the hot air is blown back to the upper surface of the base plate 410 of the food carrier 40 under the action of the fan assembly 60. At this time, the food placed in the food carrier 40 can be roasted and cooked.

[0043] In this embodiment, the cross-sectional area of ​​the first circulation channel 430 is greater than or equal to 45 cm². 2 For example, it could be 50cm2 60cm 2 The specific settings can be adjusted according to actual conditions, without any restrictions. This allows the heat generated by the heating element 50 to flow more smoothly through the first circulation channel 430 to the surface of the carrying device 40 near the upper core 30, thereby helping to heat the food in the carrying device 40 more evenly.

[0044] Furthermore, the distance between the base plate 410 of the carrying device 40 and the heating element 50 is less than or equal to 30mm, for example, it can be 10mm, 20mm, etc., without limitation. If the distance between the base plate 410 of the carrying device 40 and the heating element 50 is too large, the heat emitted by the heating element 50 will be transferred to the carrying device 40 too slowly. Therefore, setting the carrying device 40 and the heating element 50 in the above relationship can improve the heating efficiency of the heating element 50 on the carrying device 40, thereby improving the cooking efficiency of the cooking appliance 1.

[0045] In this embodiment, the carrying device 40 can be made of the same material as the inner pot 220, which will not be described in detail here. It should be noted that this embodiment does not limit the connection method between the carrying device 40 and the inner pot 220. For example, a support member can be provided on the bottom plate 410 of the carrying device 40 to separate the carrying device 40 from the bottom of the inner pot 220, thereby making the carrying device 40 suspended. Alternatively, a support member can be provided on the side plate 420 of the carrying device 40 to connect the carrying device 40 to the side plate 420 of the inner pot 220, thereby separating the carrying device 40 from the bottom of the inner pot, thereby making the carrying device 40 suspended.

[0046] The heating element 50 is disposed within the housing. In this embodiment, the heating element 50 is disposed within the inner pot of the pot body 20, and is at least partially located between the bottom plate 410 and the pot body 20. The heating element 50 may also partially extend into the first circulation channel 430, which facilitates the heating of the food-carrying device 40. Compared to other air fryers in the prior art, placing the heating element 50 in the upper core 30, below the bottom plate 410, reduces the thickness of the upper core 30, resulting in a smaller overall thickness of the cooking appliance 1. The heating element 50 can be used to heat the pot body 20, thereby cooking the food. Specifically, some of the heat generated by the heating element 50 during operation can be transferred to the pot body 20, which can then be heated. The pot body 20 can then transfer this heat to the food placed inside, allowing for traditional steaming or boiling. Simultaneously, at least a portion of the heat generated by the heating element 50 can flow through the first circulation channel 430 to the top of the bottom plate 410, achieving omnidirectional heating of the food. This embodiment does not limit the heating element 50; for example, the heating element 50 can be a heating tube or a heater, etc., and the specific choice can be made according to the actual situation.

[0047] Furthermore, in this embodiment, the minimum distance between the bottom surface of the inner pot 220 and the surface of the heating element 50 is between 5mm and 25mm. This is to prevent the bottom surface of the inner pot 220 from becoming too hot. It is understood that if the distance is too large, the entire cooking device 1 will be too large, leading to excessively high costs. In other embodiments, the heating element 50 may also be at least partially disposed between the side plate 420 and the inner wall of the pot body 20 (i.e., the inner wall of the inner pot 220). This allows for secondary heating of the airflow within the first circulation channel 430, further increasing the heating speed.

[0048] The cooking appliance 1 also includes a fan assembly 60, which is located on the upper core 30. The fan assembly 60 can be used to blow air into the pot body 20 to form an airflow circulation. When the cooking appliance 1 is in the first state, the fan assembly 60 can blow the hot airflow inside the pot body 20, so that the hot airflow inside the pot body 20 flows evenly inside the pot body 20, thereby improving the uniformity of heating the food and avoiding the situation where the food is not heated evenly, resulting in some parts being cooked while others are not.

[0049] Please continue reading. Figure 2 The blower assembly 60 includes a fan 620, which, when rotated, blows air into the pot body 20 to ensure that the hot airflow within the pot body 20 flows evenly. In one embodiment, the blower assembly 60 may further include a motor 610 and an oil filter 630.

[0050] The motor 610 can be installed on the upper mechanism 30. When the motor 610 is powered on, it can drive the fan 620 to rotate.

[0051] The fan 620 can be electrically connected to the motor 610. Furthermore, the fan 620 can be positioned in the center of the pot body 20 to allow the hot airflow inside the pot to flow more evenly within the pot body 20. Understandably, the size of the fan 620 can be set to be the same as the size of the opening in the pot body 20, which can increase the coverage area of ​​the fan 620 when it is working.

[0052] Please also refer to Figure 6 The oil filter 630 can be placed over the fan 620 and located on the side of the fan 620 facing the pot body 20. During cooking, the oil in the food evaporates during heating. If this oil adheres to the blades of the fan 620, it will affect the fan's performance, reducing airflow and causing uneven hot air circulation within the pot body 20, ultimately affecting the cooking result. Therefore, the oil filter 630 can absorb the oil that evaporates during heating, reducing the likelihood of oil adhering to the fan 620.

[0053] It is understood that in some embodiments, the oil filter 630 is detachably mounted on the fan 620. For example, the oil filter 630 can be detachably connected to the upper core 30. This allows the user to easily remove the oil filter 630 from the upper core 30 for cleaning, preventing the oil filter 630 from absorbing excessive grease, which could cause blockage and affect the normal operation of the fan assembly 60. It should be noted that this application does not limit the connection method between the oil filter 630 and the upper core 30; for example, it can be a snap-fit, tenon joint, or adhesive connection. In this embodiment, the oil filter 630 can be made of stainless steel, nylon, copper mesh, polypropylene, or stainless steel woven mesh. Since the properties of these materials are different, the specific material used can be determined according to the actual situation.

[0054] For further information, please refer to [link / reference]. Figure 2 In some embodiments, the fan assembly 60 may further include an air guide shroud 640 and an exhaust passage 650. The air guide shroud 640 can be used to guide the hot airflow, and the exhaust passage 650 can connect the inside and outside of the pot body 20 to balance the pressure.

[0055] Specifically, the air guide shroud 640 can be positioned on the side of the fan 620 away from the pot body 20. Since hot air flows upwards, and the fan 620 cannot easily blow all the hot air back into the pot body 20 for circulation, the air guide shroud 640 can collect the hot airflow on the side of the fan 620 away from the pot body 20. Then, the fan 620 can blow the hot airflow collected by the air guide shroud 640 back into the pot body 20. This helps to improve the utilization rate of the hot airflow and allows the interior of the pot body 20 to heat up quickly. The air guide shroud 640 can be configured as an inverted bowl-shaped structure. The air guide shroud 640 can be connected to the upper core 30. This embodiment does not limit the specific connection method between the air guide shroud 640 and the upper core 30. For example, it can be a detachable connection, or it can be an integrally formed structure.

[0056] If the pot body 20 is not connected to the outside, the pressure inside the pot body 20 will gradually increase during the continuous heating process of the heating element 50, which may lead to the risk of explosion. In this embodiment, one end of the exhaust channel 650 is connected to the air guide 640 and the other end is connected to the outside, which is used to balance the air pressure inside and outside the pot body 20.

[0057] For further information, please refer to [link / reference]. Figure 2 One end of the exhaust passage 650 can be connected to the top of the air guide 640, and the other end can be connected to the outside. Since most of the hot air will be blown back into the pot body 20 under the action of the fan 620, relatively little hot air can reach the top of the air guide 640. Therefore, connecting the exhaust passage 650 to the top of the air guide 640 can reduce the heat dissipation rate inside the pot body 20 and help improve the utilization rate of hot air.

[0058] By setting a loading device 40 inside the pot body 20 and placing a heating element 50 between the pot body 20 and the bottom plate 410 of the loading device 40, the heating element 50 can simultaneously heat the pot body 20 and the loading device 40. Depending on the different positions of the food, the cooking appliance 1 can realize the functions of an air fryer or an oven, thus expanding the cooking function of the cooking appliance 1.

[0059] In some embodiments, the cooking appliance 1 may further include a water-holding space formed within the inner pot 220 and located between the inner pot 220 and the bottom plate 410 of the carrying device 40. The water-holding space can hold liquids such as water. The heating element 50 can be used to heat the water container 70. In this case, the cooking appliance 1 can have a steaming or boiling function. When the water in the water-holding space is heated, steam can be generated over a large area. The steam moves through the first circulation channel 430 to the top of the bottom plate 410 to achieve cooking, improving evaporation efficiency. After water is added to the water-holding space, it can achieve the functions of frying, grilling, air-frying, stewing, and steaming.

[0060] For further information, please refer to [link / reference]. Figure 2In some embodiments, the cooking appliance 1 may further include a water container 70, which can be disposed within the pot body 20 and located between the carrying device 40 and the bottom plate 410. The water container 70 can hold liquids such as water, and the heating element 50 can be used to heat the water container 70. In this case, the cooking appliance 1 can have a steaming / cooking function. The water container 70 can generate steam over a large area, and the steam moves through the first circulation channel 430 to the top of the bottom plate 410 to achieve cooking, improving evaporation efficiency. Specifically, the user can place food in the carrying device 40 and add water to the water container 70. The heating element 50 can then heat and evaporate the water in the water container 70, thereby steaming or cooking the food placed in the carrying device 40. This allows the cooking appliance 1 to expand into more cooking modes. After adding water to the water container 70, it can achieve functions such as frying, grilling, air frying, stewing, and steaming. Specifically, the cooking appliance 1 can have two working modes. In the first mode, the water container 70 contains water, and the heating element 50 heats the water to boiling to generate steam. The lower surface of the food is heated by the bottom plate 410 of the carrying device 40, while the upper surface is heated by the steam. In the second mode, the water container 70 does not contain water, and the heating element 50 heats both the carrying device 40 and the air inside the pot body 20. The lower surface of the food is heated by the bottom plate 410 of the carrying device 40, while the upper surface is heated by the air.

[0061] For details, please refer to Figure 7 The water container 70 provided in this embodiment can be formed by a bottom wall 710 and a side wall 730. Considering that the liquid in the water container 70 may boil, causing the liquid to splash out of the water container 70, a baffle portion 740 can be provided on the side wall 730 of the water container 70. The baffle portion 740 can be arranged around the side wall 730. Furthermore, the plane where the baffle portion 740 is located can be parallel to the plane where the bottom wall 710 of the water container 70 is located, or it can have an angle with the plane where the bottom wall 710 of the water container 70 is located. The angle can be any angle between 0° and 90°, for example, it can be 45°. And the end of the baffle portion 740 away from the side wall 730 extends towards the upward movement 30. This can further prevent the liquid in the water container 70 from boiling and splashing out of the water container 70.

[0062] To improve the heating effect of the heating element 50 on the water in the water container 70, in some embodiments, the projection of the water container 70 on the bottom surface of the inner pot 220 can be configured to at least partially cover the projection of the heating element 50 on the bottom surface of the inner pot 220. In this configuration, the heating element 50 can at least partially correspond to the water container 70, allowing for faster and more efficient heating of the water in the water container 70 during the heating process, thereby improving the efficiency and quantity of steam formation. Specifically, the heating element 50 can completely correspond to the water container 70, meaning the projection of the water container 70 on the bottom surface of the inner pot 220 can be configured to completely cover the projection of the heating element 50 on the bottom surface of the inner pot 220. Of course, in other embodiments, the heating element 50 may not correspond to the water container 70.

[0063] To facilitate the installation and removal of the water container 70, the water container 70 may also be provided with a mounting part 750 protruding from the enclosure part 740. Users can hold the mounting part 750 to install and remove the water container 70. It should be noted that the specific location of the mounting part 750 is not limited in this embodiment. The mounting part 750 can be set at any position of the enclosure part 740. The shape of the mounting part 750 is also not limited. For example, the mounting part 750 can be a sheet structure or a block structure, etc. There are no restrictions here. In addition, the specific shape of the water container 70 is not limited in this embodiment. It can be set according to the actual situation to adapt to other components in the cooking appliance 1.

[0064] To make it easier for users to fill the water tank 70 with water, this embodiment of the application can also be provided with a water inlet. For details, please refer to the following: Figure 2 and Figure 8In one embodiment, the shell 10 may be provided with a water inlet 120, and the bottom surface of the pot 20 may be provided with a through hole corresponding to the water inlet 120. Specifically, the bottom surface or side wall of the inner pot 220 may be provided with a first through hole 210, and the bottom surface of the outer pot 230 may be provided with a second through hole 240. The first through hole 210 and the second through hole 240 correspond to each other and to the water inlet 120. The water container 70 is provided with a water inlet channel 720 corresponding to the first through hole 210. This facilitates the user to add water to the water container 70. For example, after the user has placed the food, water can be added to the water container 70 through the water inlet 120, avoiding the need for the user to remove the food, add water to the water container 70, and then place the food back in place, thus reducing the user's operational burden. In the above embodiment, the water inlet 120 is opened and penetrates the shell 10, allowing it to be connected to an external water source for water injection. It is understood that in other embodiments, the water inlet may not be located on the outer casing 10. For example, water can be drawn from inside the outer casing 10 to the water container 70 via an external water pipe. This is not a limitation.

[0065] In a more specific embodiment, a third seal 121 may be provided in the first through hole 210. The third seal 121 can be used to control the water inlet 120 to flow unidirectionally from the outside to the inside, so as to prevent water in the water box 70 from leaking out of the water inlet channel 720.

[0066] It should be noted that the one-way flow here means that the flow can only be from the outside of the cooking appliance 1 to the inside of the cooking appliance 1. For example, the user can use a water injector to align with the water inlet 120 and insert it into the water inlet 120. The water injector can pass through the third seal 121 located in the first channel 210 to inject water into the water container 70. When the water injector is pulled out, the water in the water container 70 cannot leak out from the third seal 121.

[0067] For details, please refer to Figure 8 The third seal 121 can be a one-way membrane. The third seal 121 can have one or more through-slots 1211, the width of which can be less than or equal to 3 mm to achieve unidirectional flow. For example, two orthogonal through-slots 1211 can be provided at the center of the third seal 121 to allow the water injector to pass through. In this embodiment, the width of the through-slots 1211 can be 1 mm, 2 mm, etc. If the width of the through-slots 1211 is too small, the water injector may have difficulty passing through the third seal 121, affecting the user's water injection. If the width of the through-slots 1211 is too large, the unidirectional sealing effect of the third seal 121 may be poor.

[0068] In some other embodiments, the third seal 121 can also be disposed in the second through hole 240, which can also serve the purpose of one-way flow, that is, water can only be injected from the outside of the cooking appliance 1 to the inside of the cooking appliance 1, and water cannot flow out from the inside of the cooking appliance 1.

[0069] Please continue reading. Figure 8 In some embodiments, the cooking appliance 1 may further include a second seal 122. The second seal 122 may be disposed in the gap between the water inlet channel 720 and the first through hole 210 to prevent water injected by the user from the water inlet 120 from flowing out through the gap between the water inlet channel 720 and the first through hole 210 and entering the internal space of the cooking appliance 1, which could cause scale formation in the internal space of the cooking appliance 1 or damage to electronic components such as circuit boards in the internal space of the cooking appliance 1. It should be noted that the embodiments of this application do not limit the shape, structure, etc. of the second seal 122, and the specific choice can be made according to the actual situation.

[0070] In this embodiment, the third seal 121 and the second seal 122 can be made of the same material, such as rubber, silicone, polyurethane, etc. There are no restrictions here. The specific design can be determined based on the usage scenario and cost.

[0071] For further information, please refer to [link / reference]. Figure 9 In some embodiments, a notch 1212 may be provided at the edge of the third seal 121. The notch 1212 facilitates the user to install the third seal 121 into the water inlet 120. It should be noted that in this embodiment, the third seal 121 and the water inlet 120 can be interference-fitted. When the third seal 121 is installed in the water inlet 120, the notch 1212 can abut against the inner wall of the water inlet 120 to prevent water leakage from the water container 70.

[0072] Please also refer to Figure 2 and Figure 10 In one embodiment, the cooking appliance 1 may further include: a fixing member 80, which may be disposed inside the pot body 20, specifically inside the inner pot 220 and between the inner pot 220 and the bottom plate 410 of the carrying device 40; a heating element 50 is disposed on the fixing member 80, that is, the fixing member 80 may be used to support the heating element 50; in addition, the heating element 50 may be arranged around the water container 70, so that the heat is distributed more evenly during the heating process of the heating element 50 on the water container 70.

[0073] In this embodiment, the interior of the fixing member 80 can be a hollow structure, allowing at least a portion of the heating element 50 to be embedded within it. The fixing member 80 serves to secure the heating element 50. Simultaneously, a first sealing element can be provided at the connection between the heating element 50 and the fixing member 80 to prevent water or moisture from entering the interior of the fixing member 80.

[0074] In other embodiments, the fastener 80 can also be used to support the carrying device 40, that is, the carrying device 40 can be placed on the fastener 80 at least partially. In this case, the fastener 80 can guide the installation of the carrying device 40. The user can first roughly align the carrying device 40 with the fastener 80, and then make fine adjustments, and finally install the carrying device 40 in the inner pot 220.

[0075] For further details, please refer to the following: Figure 2 In one embodiment, the cooking appliance 1 may further include a frying basket 90, which is detachably disposed within the pot body 20 and located above the carrying device 40. In this case, the cooking appliance 1 can have a frying function. Specifically, the user can place food in the frying basket 90 and pour cooking oil into it. The heating element 50 then generates heat to heat the inner pot 220, thereby frying the food placed in the frying basket 90. This allows the cooking appliance 1 to offer more cooking modes.

[0076] Furthermore, a second circulation channel 910 may be provided between the frying basket 90 and the inner wall of the pot body 20. The first circulation channel 430 is connected to the second circulation channel 910. This allows the hot airflow generated by the heating element 50 to heat the frying basket 90 through the first circulation channel 430 and the second circulation channel 910, thereby improving the heating efficiency of the heating element 50 on the frying basket 90 and thus improving cooking efficiency. It should be noted that the embodiments of this application do not limit the specific shape and structure of the frying basket 90, and can be set according to actual conditions to adapt to other components in the cooking appliance 1.

[0077] In a more specific implementation, please refer to [link / reference needed]. Figure 2Ventilation holes 920 can also be provided on the bottom and / or side wings of the frying basket 90. Multiple ventilation holes 920 can be provided and evenly distributed on the bottom and / or side wings of the frying basket 90. At the same time, the projection of the ventilation holes 920 on the bottom surface of the pot body 20 is located inside the projection of the carrying device 40 on the bottom surface of the pot body 20. Since oil in the frying basket 90 will inevitably splash out of the frying basket 90 when cooking fried or deep-fried foods, the above-mentioned structure of the carrying device 40 and the frying basket 90 can use the carrying device 40 to catch the oil splashed from the frying basket 90, preventing oil from splashing into the inner pot 220. In this way, after cooking, the user can only clean the frying basket 90 and the carrying device 40, reducing the user's cleaning burden.

[0078] Furthermore, the distance between the frying basket 90 and the base plate 410 of the carrying device 40 is greater than or equal to 3mm. This allows the carrying device 40 and the frying basket 90 to work simultaneously. For example, a user can place food to be baked in the carrying device 40 and food to be fried in the frying basket 90. After activating the heating element 50, both foods can be cooked simultaneously, improving cooking efficiency. If the aforementioned distance is too small, it will be difficult to use the carrying device 40 while using the frying basket 90.

[0079] The cooking appliance 1 provided in this application embodiment has a loading device 40 set inside the pot body 20 and a heating element 50 set between the pot body 20 and the bottom plate 410 of the loading device 40. The heating element 50 heats both the pot body 20 and the loading device 40 simultaneously. The heating element 50 heats the pot body, which can be used for traditional steaming and boiling of the food placed in the pot body 20. The hot airflow generated by the heating element 20 can flow to the top of the loading device 40 through the first circulation channel 430 set between the bottom plate 410 of the loading device 40 and the inner wall of the pot body 20. Under the action of the fan assembly 60, the hot airflow can be blown to the surface of the loading device 40, thereby baking and cooking the food in the loading device 40. The cooking appliance 1 provided in this application embodiment can realize the functions of steaming, boiling, stewing and frying. By setting the heating element 50 inside the shell, the hot airflow circulates and heats the food placed on the loading device 40 through the first circulation channel 430, which can realize the functions of electric hot pot and air fryer at the same time.
