Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, and more specifically, to an upper mechanism device and a cooking appliance. Background Technology

[0002] An air fryer is a cooking appliance that uses heat to fry food. Specifically, an air fryer includes a heating element and a fan inside the fryer. The heating element heats the air inside the fryer, and the fan blows the hot air into the fryer to heat the food. The hot air circulates within the fryer, thereby dehydrating the food and achieving a frying effect.

[0003] However, after using an air fryer for a period of time, especially after cooking foods with a high oil content, a large amount of oil stains will accumulate on the surface of the heating element and the air guide shroud on the fan. Because the heating element blocks the air guide shroud, it increases the difficulty of cleaning the oil stains on the air guide shroud. Summary of the Invention

[0004] This application provides an upper mechanism device and a cooking appliance.

[0005] According to a first aspect of this application, an embodiment of this application provides an upper mechanism device. This upper mechanism device is used to cover a pot body having a cooking cavity. The upper mechanism device includes a lid assembly, a heating mechanism, a baffle mechanism, and an air circulation mechanism. The lid assembly has a mounting cavity with an opening on one side; when the lid assembly covers the pot body, the opening faces the cooking cavity; the heating mechanism is disposed within the mounting cavity; the baffle mechanism is disposed within the mounting cavity and seals the opening to isolate the mounting cavity from the cooking cavity; the air circulation mechanism includes a drive member and a first impeller, the drive member being disposed within the lid assembly, and the first impeller being disposed on the side of the baffle mechanism opposite to the mounting cavity and connected to the drive member.

[0006] According to a second aspect of this application, embodiments of this application also provide a cooking appliance, which includes a pot body and the aforementioned upper mechanism device. The pot body has a cooking cavity, and the upper mechanism device covers the cooking cavity.

[0007] This application provides an upper heating element device and a cooking appliance. The upper heating element device is used to cover a pot body with a cooking cavity. The cover device has a mounting cavity for housing a heating mechanism, and a baffle mechanism is disposed between the mounting cavity and the cooking cavity, covering the opening formed by the mounting cavity. When the heating mechanism is working, oil stains generated in the cooking cavity are blocked by the baffle mechanism, thus preventing them from entering the mounting cavity. The baffle mechanism effectively isolates components in the mounting cavity, such as the heating mechanism, preventing them from being contaminated by oil stains. Therefore, the upper heating element device provided by this application can, on the one hand, prevent the heating mechanism in the mounting cavity from becoming contaminated with oil, thereby reducing heating efficiency. On the other hand, since the oil stains accumulate on the baffle mechanism, when the user needs to clean the upper heating element device later, only the oil stains on the baffle mechanism need to be cleaned, reducing the difficulty of cleaning oil stains.

[0008] In addition, the upper mechanism also includes an air circulation mechanism. The first impeller of the air circulation mechanism is located on the side of the baffle mechanism away from the mounting cavity. That is, when the upper mechanism covers the pot, the first impeller is located inside the cooking cavity. Therefore, when the first impeller rotates, it can convert the heat energy generated by the heating mechanism into hot air inside the cooking cavity, thereby accelerating the air circulation speed inside the cooking cavity and improving the cooking efficiency of the food in the cooking cavity.

[0020] 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 only a part of the embodiments of the present application, and not all of them. 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.

[0021] Please see Figure 1 and Figure 2 This application provides an upper heating element device 100 and a cooking appliance 200 equipped with the upper heating element device 100. The cooking appliance 200 is a cooking appliance that can use heat to fry food. During operation, the cooking appliance 200 generates hot air through a heating element inside the pot, and then uses a fan to blow the high-temperature air into the pot to heat the food. The hot air circulates within the pot, thereby dehydrating the food to achieve a frying effect. In this embodiment, the cooking appliance 200 may include a pot body 210 and an upper heating element device 100. The pot body 210 has a cooking cavity 2100 for holding the food to be cooked. The upper heating element device 100 covers the cooking cavity 2100 on the pot body 2100 and is used to heat the food inside the cooking cavity 2100.

[0022] In some possible embodiments, the cooking appliance 200 can also use the heat generated by the upper heat source to cook, stir-fry, or perform other operations on the food in the cooking cavity 2100.

[0023] In some possible embodiments, the cooking appliance 200 is a flip-top cooking appliance, with one side of the upper core device 100 rotatably connected to the pot body 210. When the user needs to clean the upper core device 100, they only need to flip it open to complete the cleaning work. In other possible embodiments, the cooking appliance 200 is a pull-out type, with the upper core device 100 forming the upper core of the cooking appliance, integrally formed or assembled with the outer shell structure of the pot body. Specifically, the cooking appliance 200 can be an air fryer (e.g., a flip-top air fryer, a pull-out air fryer), an air oven, etc., and this embodiment does not specifically limit it.

[0024] Please see Figures 2 to 4 The upper heating element device 100 includes a cover assembly 120, a heating mechanism 140, a baffle mechanism 160, and an air circulation mechanism 180. The cover assembly 120 has a mounting cavity 1200, with an opening 1210 on one side. When the cover assembly 120 covers the pot body 210, the opening 1210 faces the cooking cavity 2100. The heating mechanism 140 is disposed within the mounting cavity 1200. The baffle mechanism 160 is disposed within the mounting cavity 1200 and seals the opening 1210, thus isolating the mounting cavity 1200 from the cooking cavity 2100. Therefore, the upper heating element device 100 provided in this application can, on the one hand, prevent the heating mechanism 140 within the mounting cavity 1200 from becoming contaminated with oil, thereby reducing heating efficiency. On the other hand, since the oil accumulates on the baffle mechanism 160, when the user needs to clean the upper heating element device 100, only the oil on the baffle mechanism 160 needs to be cleaned, reducing the difficulty of cleaning the oil. In addition, after the heating mechanism 140 transfers heat to the baffle mechanism 160, the entire baffle mechanism 160 acts as a heat source. The heat radiated downwards by the baffle mechanism 160 will be more even, effectively improving the cooking effect of the cooking appliance 200.

[0025] The air circulation mechanism 180 includes a drive member 1800 and a first impeller 1810. The drive member 1800 is disposed on the lid assembly 120, and the first impeller 1810 is disposed on the side of the baffle mechanism 160 opposite to the mounting cavity 1200 and connected to the drive member 1800. Therefore, when the upper core device 100 covers the pot body 210, the first impeller 1810 is located inside the cooking cavity 2100. When the first impeller 1810 rotates under the drive of the drive member 1800, it can convert the heat energy generated by the heating mechanism 140 into hot air inside the cooking cavity 2100, thereby accelerating the air circulation speed inside the cooking cavity 2100 and improving the cooking efficiency of the food in the cooking cavity 2100. In addition, when the cooking appliance 200 performs the boiling function, the air circulation mechanism 180 can not only make the heat transfer more even, but also break bubbles to prevent excessive bubbles from overflowing after the food boils, thus ensuring that the cooking appliance 200 is more hygienic.

[0026] The following is a detailed description of each mechanism in the upper movement assembly 100.

[0027] Please see Figure 6 and Figure 7 The lid assembly 120 may include a mounting shell 1230 for connecting the pot body 210. In some possible embodiments, the pot body 210 may include a connector, and the mounting shell 1230 may include a mating part that matches the connector. The mounting shell 1230 is movably connected to the pot body 210 or detachably connected to the pot body 210 through the mating connection between the connector and the mating part.

[0028] In this embodiment, the mounting shell 1230 may include a support portion 1232 and a surrounding portion 1234. The support portion 1232 is disposed above the pot body 210 and fixedly connected to the surrounding portion 1234. The support portion 1232 has the aforementioned mounting cavity 1200, with an opening 1210 formed on one side of the mounting cavity 1200; that is, the opening 1210 of the mounting cavity 1200 is defined by the support portion 1232. The support portion 1232 is also used to fix the drive member 1800 on the air circulation mechanism 180. Specifically, the support portion 1232 may have a fixing groove through which the drive member 1800 is mounted to the support portion 1232.

[0029] The surrounding portion 1234 surrounds the outer periphery of the support portion 1232, is spaced apart from at least a portion of the structure of the support portion 1232, and is used to connect the pot body 210. Specifically, the support portion 1232 and the surrounding portion 1234 can be integrally formed, for example, by stamping or hot pressing using a polymer material (e.g., plastic), making the connection between the support portion 1232 and the surrounding portion 1234 more stable.

[0030] Please refer to it again. Figure 3 and Figure 4 The heating mechanism 140 may include a heating element 1400, which is disposed in the mounting cavity 1200 and is used to heat the air in the mounting cavity 1200.

[0031] In some possible embodiments, the heating element 1400 may include a metal tube 1401, which is disposed within the mounting cavity 1200. Specifically, the metal tube 1401 is a heating device made by inserting an electric heating wire into a metal tube body (e.g., carbon steel tube, titanium tube, stainless steel tube, copper tube), which has the characteristics of fast heating rate, small thermal hysteresis, uniform heating, long heat radiation transfer distance, and fast heat exchange speed. In some possible embodiments, the heating element 1400 may include a carbon tube 1403, which is disposed within the mounting cavity 1200. Specifically, the carbon tube 1403 is a heating device that uses carbon fiber as a heat transfer medium, which has the characteristics of long service life and high electrothermal conversion efficiency. In some possible embodiments, the heating element 1400 may include an infrared tube 1405, which is disposed within the mounting cavity 1200. Specifically, the infrared tube 1405 is a tubular heater made using the principle of infrared radiation, which has the characteristics of high thermal efficiency, high power density, and high heating rate. In some possible embodiments, the heating element 1400 may include a light wave tube 1407 disposed within the mounting cavity 1200. Specifically, the light wave tube 1407 is a device that uses light wave technology to heat food by emitting visible light and far-infrared light, and it features high heating efficiency and high heating rate.

[0032] In some other possible embodiments, the heating element 1400 may include a heating array circuit (not shown in the figure), which is integrated into the baffle mechanism 160. The heating array circuit is formed by mixing superconducting ceramic material micropowder with an organic binder to form a paste, and then printing the paste onto a substrate material in the form of circuit wiring or patterns using screen printing technology. It features high power density, fast heating speed, high operating temperature, rapid temperature rise rate, and uniform heating temperature field. Specifically, the heating array circuit can be integrated on the side of the baffle mechanism 160 facing the mounting cavity 1200, or it can be integrated on the side of the baffle mechanism 160 away from the mounting cavity 1200; this embodiment does not specifically limit this. It should be noted that "integrated into" the baffle mechanism 160 can mean that the heating array circuit covers or adheres to the surface of the baffle mechanism 160; alternatively, the baffle mechanism 160 can be used as the substrate material for the heating array circuit, with the heating array circuit directly printed on its surface.

[0033] In this embodiment, the heating mechanism 140 may further include a heat insulation member 1410. The heat insulation member 1410 is disposed within the mounting cavity 1200 and is used to isolate the heat generated by the heating mechanism 140 from the outside of the upper core device 100 to prevent the user from accidentally touching the upper core device 100 and causing burns. Specifically, the heat insulation member 1410 is disposed within the bracket portion 1232 and is located on the side of the heating element 1400 opposite to the cooking cavity 2100, to insulate the heat generated by the heating element 1400. In this embodiment, the heat insulation member 1410 is located between the heating element 1400 and the driving member 1800. When the heating element 1400 is in the working state, the heat insulation member 1410 can reduce the impact of the heat generated by the heating element 1400 on the driving member 1800, thereby ensuring the service life of the driving member 1800. Figure 4 In the illustrated embodiment, the heat insulation component 1410 is generally a shell-like structure, with a heat insulation cavity 1412 on the side facing the opening 1210. The heating component 1400 is disposed within the heat insulation cavity 1412, and the baffle mechanism 160 covers the opening of the heat insulation cavity 1412. Therefore, the heat generated by the heating component 1400 is introduced into the cooking cavity 2100 through the baffle mechanism 160 under the insulation of the heat insulation component 1410, improving the heat utilization efficiency of the upper core device 100. Specifically, the heat insulation component 1410 can be made of heat insulation materials such as ceramics, glass fiber, asbestos, rock wool, and silicates; this embodiment is not limited to this. In some possible embodiments, a heat insulation coating can be applied to the inner surface of the heat insulation component 1410, that is, the side of the heat insulation component 1410 facing the heating component 1400, to improve the heat insulation effect of the heat insulation component 1410. Specifically, the heat insulation coating can be a heat insulation coating containing rare earth elements.

[0034] In this embodiment, the heating mechanism 140 may further include a high-temperature resistant component 1420. Specifically, the high-temperature resistant component 1420 may be a heat-insulating mica sheet, which is a heat-insulating material made of materials such as polysilicon mica and quartz. The heat-insulating mica sheet 1420 may be disposed between the heat-insulating component 1410 and the heating component 1400. For details, please refer to [link to relevant documentation]. Figure 5 The heat-insulating mica sheet 1420 can be attached to the side of the heat insulation member 1410 facing the heating member 1400 to further block the heat radiated from the heating member 1400 to the heat insulation member 1410, thereby ensuring the service life of the drive member 1800. In some other possible embodiments, the heat-insulating mica sheet 1420 can also be disposed on the side of the heat insulation member 1410 away from the heating member to improve the heat blocking effect.

[0035] When a high-efficiency heating element 1400 (e.g., a light wave tube) is used, the high-temperature resistant element 1420 can reduce the heat transferred to the drive element 1800, thereby improving its service life. In addition, when the high-temperature resistant element 1420 is sandwiched between two adjacent structures, it can also reduce friction and lower noise.

[0036] In this embodiment, the heating mechanism 140 may further include a reflector 1430, which is disposed between the heat insulation member 1410 and the heating member 1400, and is used to reflect the heat generated by the heating member 1400. Specifically, the reflector 1430 is disposed within the heat insulation cavity 1412, and a reflective cavity 1432 is provided on the side of the reflector 1430 facing the opening 1210. The heating member 1400 is disposed within the reflective cavity 1432, and the baffle mechanism 160 covers the opening of the reflective cavity 1430. Therefore, the heat generated by the heating member 1400 will enter the cooking cavity 2100 through the baffle mechanism 160 after being reflected by the reflector 1430, thereby improving the heating efficiency of the upper core device 100. In some possible embodiments, the inner surface of the reflector 1430, that is, the surface of the reflective cavity 1432, has a low surface roughness, for example, the surface is a polished surface, which improves the heat reflection efficiency of the reflector 1430.

[0037] Please see Figure 8 In some embodiments, the reflector 1430 may include a peripheral wall 1436 and a reflective boss 1438, which are smoothly transitioned together. In other embodiments, the reflector 1430 may include a bottom wall 1434, a peripheral wall 1436, and a reflective boss 1438. The reflective boss 1438 is generally located in the middle of the reflector 1430, and the bottom wall 1434 connects the peripheral wall 1436 and the reflective boss 1438. The peripheral wall 1436 and the reflective boss 1438 are spaced apart to jointly define the reflective cavity 1432. Specifically, the bottom wall 1434, the peripheral wall 1436, and the reflective boss 1438 may be an integrally formed structure, for example, formed by stamping from a sheet metal. In this embodiment, the heating element 1400 can be a tubular heating element such as a metal tube 1401, a carbon tube 1403, an infrared tube 1405, and a light wave tube 1407. The tubular heating element is arranged around the outer periphery of the reflective boss 1438 and spaced apart from the reflective boss 1438. That is, the tubular heating element is arranged between the reflective boss 1438 and the peripheral wall 1436.

[0038] Specifically, the reflective protrusion 1438 is approximately frustum-shaped; for example, its surface is conical. Therefore, when heat generated by the tubular heating element radiates onto the surface of the reflective protrusion 1438, it reflects the heat outwards to the baffle mechanism 160. In this embodiment, by providing the reflective protrusion 1438, the surface area of ​​the reflector 1430 can be increased, thereby improving the heat reflection efficiency of the reflector 1430. Furthermore, the bottom wall 1434 and the baffle mechanism 160 are approximately parallel, and the angle between the peripheral wall 1436 and the bottom wall 1434 can be greater than 90 degrees and less than 150 degrees. Therefore, when heat generated by the tubular heating element radiates onto the peripheral wall 1436, the peripheral wall 1436 reflects the heat inwards to the baffle mechanism 160, thus avoiding dead zones in heat radiation.

[0039] In some possible embodiments, the reflector 1430 can be made of a heat-insulating material such as ceramic, and a heat-reflecting layer can be provided on the side of the ceramic material facing the heating element 1400. The reflector 1430 can reflect heat through the heat-reflecting layer while also isolating heat. Specifically, the heat-reflecting layer can be a metal oxide coating sprayed onto the surface of the reflector 1430, or a reflective film (e.g., an aluminized film, an aluminized polyester film, an aluminized polyimide film, etc.) attached to the surface of the reflector 1430. Therefore, with the reflector 1430 provided, the upper movement device 100 does not need to provide a heat-insulating element 1410, thus saving material costs and making the structure of the upper movement device 100 more compact. In some other possible embodiments, the heating element 1400 may be a heating array circuit. Since the heating array circuit is directly integrated on the baffle mechanism 160, it is not necessary to provide a reflector 1430 in the upper movement device 100, thereby saving material costs of the upper movement device 100 and making the structure of the upper movement device 100 more compact.

[0040] Please refer to it again. Figure 4 The baffle mechanism 160 may include a heat-conducting baffle 1600 and a baffle support 1610. The heat-conducting baffle 1600 is used to seal the opening 1210 on the mounting cavity 1200. Specifically, the heat-conducting baffle 1600 may be made of materials such as glass or metal. In some possible embodiments, the heating element 1400 may be a heating array circuit, which may be integrated on the surface of the heat-conducting baffle 1600.

[0041] In some possible embodiments, the baffle bracket 1610 can be fixed around the outer periphery of the heat-conducting baffle 1600 and fixedly connected to the mounting housing 1230. That is, the heat-conducting baffle 1600 is connected to the mounting housing 1230 through the baffle bracket 1610, and together with the baffle bracket 1610, it seals the opening 1210. Therefore, during the use of the cooking appliance 200 equipped with this upper core device 100, the oil stains in the cooking cavity 2100 are blocked by the heat-conducting baffle 1600 and the baffle bracket 1610, preventing them from entering the mounting cavity 1200, thereby avoiding oil stains on the components (e.g., heating element 1400, heat insulation element 1410, etc.) in the mounting cavity 1200. When the user needs to clean the upper core device 100 later, only the oil stains on the heat-conducting baffle 1600 and the baffle bracket 1610 need to be cleaned, reducing the difficulty of cleaning oil stains.

[0042] In other possible embodiments, the baffle bracket 1610 may also be fixed around the outer periphery of the heat-conducting baffle 1600 and fixedly connected to the heat insulation member 1410, so that the heat-conducting baffle 1600 can be connected to the heat insulation member 1410 through the baffle bracket 1610. The heat-conducting baffle 1600 can prevent oil from entering the heat insulation cavity 1412, thereby preventing the devices (e.g., the heating element 1400) in the heat insulation cavity 1412 from being contaminated with oil, thus reducing the difficulty of subsequent oil cleaning.

[0043] Please see Figure 9 The baffle support 1610 is generally annular in shape and may include a main body 1612, a first support portion 1614, and a second support portion 1616. The main body 1612 is generally annular in shape. The first support portion 1614 is connected to one side (also called the inner side) of the main body 1612 and extends in the direction of the heat-conducting baffle 1600. The second support portion is connected to the other side (also called the outer side) of the main body 1612 and extends in the direction away from the heat-conducting baffle 1600. As an example, the main body 1612, the first support portion 1614, and the second support portion 1616 may be an integrally formed structure, for example, formed by stamping from a sheet metal.

[0044] The plane of the main body 1612 is approximately parallel to or coplanar with the plane of the heat-conducting baffle 1600. The main body 1612 is used to support the reflector 1430 and the heat insulation member 1410. Specifically, the reflector 1430 may further include a first flange 1439, which is connected to the end of the peripheral wall 1436 of the reflector 1430 away from the bottom wall 1434 and extends radially away from the reflective cavity 1432. The reflector 1430 is stacked on the main body 1612 through the first flange 1439.

[0045] Furthermore, the heat insulation member 1410 can be stacked on the first flange portion 1439 to jointly fix the first flange portion 1439 of the reflector 1430 with the main body portion 1612, thereby improving the integration of the heating mechanism 140. Specifically, the heat insulation member 1410 may include a body 1414 and a second flange portion 1416. The body 1414 is used to form the aforementioned heat insulation cavity 1412, which is disposed on the side of the body 1414 facing the opening 1210. The second flange portion 1416 is connected to the lip of the body 1414 and extends radially away from the heat insulation cavity 1412. When the reflector 1430 is stacked on the main body 1612, the heat insulation member 1410 is stacked on the first flange 1439 of the reflector 1430 through the second flange 1416, so that the first flange 1439 is located between the second flange 1416 and the main body 1612. The three can be fixed by adhesive, by threaded fasteners, or by mechanical buckles or slots.

[0046] The first support portion 1614 is connected to the inner edge of the main body portion 1612 and is axially offset relative to the main body portion 1612, so that the connection structure between the first support portion 1614 and the main body portion 1612 is approximately stepped, so that the first support portion 1614 can be used to support the heat-conducting baffle 1600 and limit the heat-conducting baffle 1600. Specifically, when the main body portion 1612 covers and is connected to the first flange portion 1439 of the reflector 1430, the heat-conducting baffle 1600 can be stacked on the side of the first support portion 1614 facing the reflector 1430 and fixedly connected to the first support portion 1614. Therefore, the heat-conducting baffle 1600 and the baffle bracket 1610 can together cover the reflective cavity of the reflector 1430 relatively tightly.

[0047] The second support portion 1616 is connected to the outer edge of the main body portion 1612 and is bent relative to the main body portion 1612, so that the second support portion 1616 is axially offset relative to the main body portion 1612, making the connection structure between the second support portion 1616 and the main body portion 1612 approximately stepped, so that the second support portion 1616 can be used to support the protective baffle 1630 and limit the protective baffle 1630. Specifically, the second support portion 1616 and the second flange portion 1416 of the heat insulation member jointly define the support space, and part of the structure of the protective baffle 1630 can be inserted into the support space. Specifically, the second bearing portion 1616 and the second flange portion 1416 of the heat insulation component are arranged axially at intervals. The edge portion of the protective baffle 1630 can be stacked on the second bearing portion 1616 and located between the second bearing portion 1616 and the second flange portion 1416. The three can be fixed by adhesive bonding, by threaded fasteners, or by mechanical buckles or slots.

[0048] In this embodiment, the reflector 1430, heat insulation component 1410, heat-conducting baffle 1600, and protective baffle 1630 are assembled together by the baffle bracket 1610 to form an integral module, making the structure of the upper mechanism device 100 more compact and easier to assemble and disassemble. Specifically, when disassembling the upper mechanism device 100, simply disassemble the baffle bracket 1610 first, and then the heat-conducting baffle 1600, protective baffle 1630, reflector 1430, and heat insulation component 1410 can be disassembled in sequence, so as to facilitate cleaning of the heat-conducting baffle 1600 and baffle bracket 1610, and replacement of the reflector 1430 and heat insulation component 1410.

[0049] In some possible embodiments, the area of ​​the heat-conducting baffle 1600 is almost the same as the projected area of ​​the opening 1210 on the mounting cavity 1200. In this case, there is no need to provide a baffle bracket 1610 in the upper movement assembly 100, thereby saving material costs for the upper movement assembly 100.

[0050] In this embodiment, the baffle mechanism 160 may further include a protective baffle 1630. See also... Figure 6 and Figure 7 A protective baffle 1630 is disposed between the support portion 1232 and the surrounding portion 1234. When the lid assembly 120 covers the pot body 210, the protective baffle 1630 and the heat-conducting baffle 1600 together cover the opening of the cooking cavity 2100. Specifically, the protective baffle 1630 can be made of a transparent material (e.g., quartz glass, silicate glass, etc.), so when cooking food in the cooking cavity 2100, the user can observe the cooking process of the food through the protective baffle 1630, reducing the probability of the food burning. Specifically, when the heat-conducting baffle 1600 closes the opening 1210 of the mounting cavity 1200 on the bracket part 1232 through the baffle bracket 1610, one end of the protective baffle 1630 can be pressed against the second bearing part 1616 of the baffle bracket 1610, and the other end is connected to the surrounding part 1234. That is, the protective baffle 1630, the heat-conducting baffle 1600 and the baffle bracket 1610 together cover the opening of the cooking cavity 2100.

[0051] In this embodiment, the baffle mechanism 160 may further include a retaining ring 1650, which is used to cover the pot body 210. Specifically, the retaining ring 1650 is generally ring-shaped, and it is arranged around the outer periphery of the protective baffle 1630 and fixedly connected to the surrounding portion 1234. That is, the mounting shell 1230 is connected to the pot body 210 through the retaining ring 1650. Please refer to the following documents respectively. Figure 4 , Figure 6 and Figure 10A first vent 1236 is provided in the surrounding part 1234, and a second vent 1651 communicating with the first vent 1236 is provided in the fixing ring 1650. When the upper core device 100 seals the pot body 210, the first vent 1236 communicates with the cooking cavity 2100 and the outside through the second vent 1651. Therefore, when the cooking appliance 200 is in working condition, hot air in the cooking cavity 2100 can be discharged through the first vent 1236 and the second vent 1651, so that the air pressure in the cooking cavity 2100 is consistent with the outside atmospheric pressure.

[0052] The air circulation mechanism 180 may include a drive element 1800 and a first impeller 1810, with the drive element 1800 disposed on the cover assembly 120. Specifically, the drive element 1800 may be a rotary drive element, such as a rotary motor with a built-in gearbox, or a rotary servo motor, rotary cylinder, or other rotary drive device.

[0053] The first impeller 1810 is disposed on the side of the baffle mechanism 160 opposite to the mounting cavity 1200 and connected to the drive member 1800. When the first impeller 1810 rotates under the drive of the drive member 1800, it can convert the heat energy generated by the heating mechanism 140 into hot air in the cooking cavity 2100, thereby accelerating the air circulation speed in the cooking cavity 2100 and improving the cooking efficiency of the food in the cooking cavity 2100. Specifically, the shape of the blades in the first impeller 1810 can be quadrilateral, vine-like, wing-like, etc., and the number of blades can be 3, 5, 7, etc., which is not limited in this embodiment.

[0054] In some possible embodiments, the first impeller 1810 is detachably connected to the drive member 1800. On the one hand, after the first impeller 1810 is removed, the baffle mechanism 160 exposes a larger cleanable area, improving cleaning convenience; on the other hand, removing the first impeller 1810 makes it easier to clean the impeller separately. Furthermore, when the first impeller 1810 is not needed, it can be removed and stored separately to extend its service life.

[0055] In this embodiment, please refer again. Figure 4 The air circulation mechanism 180 also includes an output shaft 1830 and a second impeller 1850. The output shaft 1830 passes through the cover assembly 120, with one end connected to a drive member 1800 and the other end connected to the first impeller 1810. That is, the drive member 1800 drives the first impeller 1810 to rotate via the output shaft 1830. Specifically, the first impeller 1810 is detachably connected to the other end of the output shaft 1830.

[0056] The second impeller 1850 is connected to the output shaft 1830, and the second impeller 1830 and the first impeller 1810 are respectively disposed on opposite sides of the baffle mechanism 160. Figure 4 In this embodiment, the second impeller 1850 is positioned away from the opening of the heat insulation cavity 1420 and is located between the heat insulation component 1410 and the driving component 1800. Therefore, when the driving component 1800 drives the second impeller 1850 to rotate via the output shaft 1830, it can reduce the heat between the heat insulation component 1410 and the driving component 1800, thereby achieving a heat dissipation effect on the driving component 1800 and ensuring its service life. Specifically, the shape of the blades in the second impeller 1850 can be quadrilateral, vine-like, wing-like, etc., and the number of blades can be 3, 5, 7, etc. The shape of the second impeller 1850 can be the same as or different from that of the first impeller 1810; this embodiment does not limit this.

[0057] This embodiment provides an upper heating element device 100, which includes a cover assembly 120, a heating mechanism 140, a baffle mechanism 160, and an air circulation mechanism 180. The cover assembly 120 has a mounting cavity 1200, with an opening 1210 formed on one side. When the cover assembly 120 covers the pot body 210, the opening 1210 faces the cooking cavity 2100. The heating mechanism 140 is disposed within the mounting cavity 1200. The baffle mechanism 160 is disposed within the mounting cavity 1200 and seals the opening 1210, thus isolating the mounting cavity 1200 from the cooking cavity 2100. Therefore, the upper heating element device 100 provided in this application can prevent the heating mechanism 140 within the mounting cavity 1200 from becoming contaminated with oil, thereby reducing heating efficiency. On the other hand, since the oil stains accumulate on the baffle mechanism 160, when the user needs to clean the upper mechanism 100, they only need to clean the oil stains on the baffle mechanism 160, which reduces the difficulty of cleaning the oil stains.

[0058] Furthermore, the air circulation mechanism 180 includes a drive member 1800 and a first impeller 1810. The drive member 1800 is disposed on the lid assembly 120, and the first impeller 1810 is disposed on the side of the baffle mechanism 160 opposite to the mounting cavity 1200 and connected to the drive member 1800. Therefore, when the upper core device 100 covers the pot body 210, the first impeller 1810 is located inside the cooking cavity 2100. When the first impeller 1810 rotates under the drive of the drive member 1800, it can convert the heat energy generated by the heating mechanism 140 into hot air inside the cooking cavity 2100, thereby accelerating the air circulation speed inside the cooking cavity 2100 and improving the cooking efficiency of the food in the cooking cavity 2100. In addition, when the cooking appliance 200 performs the boiling function, the air circulation mechanism 180 can not only make the heat transfer more even, but also break bubbles to prevent excessive bubbles from overflowing after the food boils, thus ensuring that the cooking appliance 200 is more hygienic.
