Description

Technical Field

[0001] The present application relates to the technical field of cooking utensils, and more specifically, to an upper movement device and a cooking utensil. Background Art

[0002] An air fryer is a cooking appliance that can fry food with heat. Specifically, the air fryer includes a heating tube and a fan arranged in the pot body, wherein the heating tube is used to heat the air in the pot body, and the fan is used to blow hot air into the pot to heat the food, so that the hot air can circulate in the pot body, thereby dehydrating the food to achieve the effect of frying the food.

[0003] However, after the air fryer has been used for a period of time, especially after cooking food with a high oil content, a large amount of oil stains will accumulate on the surface of the heating tube and the surface of the air guide cover on the fan. Since the air guide cover is blocked by the heating tube, it is more difficult to clean the oil stains on the air guide cover. Summary of the invention

[0004] The embodiments of the present application provide an upper movement device and a cooking utensil.

[0005] According to the first aspect of the present application, an embodiment of the present application provides an upper movement device. The upper movement device is used to cover a pot body with a cooking cavity. Among them, the upper movement device includes a cover body assembly, a heating mechanism, a baffle mechanism and an air circulation mechanism. The cover body assembly is provided with an installation cavity, and the installation cavity forms an opening on one side of the cover body assembly; when the cover body assembly covers the pot body, the opening faces the cooking cavity; the heating mechanism is arranged in the installation cavity; the baffle mechanism is arranged in the installation cavity and covers the opening to isolate the installation cavity from the cooking cavity; the air circulation mechanism includes a driving member and a first impeller, the driving member is arranged in the cover body assembly, and the first impeller is arranged on the side of the baffle mechanism away from the installation cavity and connected to the driving member.

[0006] According to the second aspect of the present application, the present application also provides a cooking utensil, which includes a pot body and the upper movement device mentioned above, wherein the pot body is provided with a cooking cavity, and the upper movement device covers the cooking cavity.

[0007] The present application provides an upper movement device and a cooking utensil, wherein the upper movement device is used to cover a pot body having a cooking cavity. The cover body device is provided with an installation cavity for placing a heating mechanism, and the baffle mechanism is arranged between the installation cavity and the cooking cavity, and covers the opening formed by the installation cavity. When the heating mechanism is working, the oil stains generated in the cooking cavity will be blocked by the baffle mechanism and cannot enter the installation cavity. The baffle mechanism can effectively isolate the components in the installation cavity, such as the heating mechanism, so that these components are protected from oil stains. Therefore, the upper movement device provided by the present application can, on the one hand, prevent the heating mechanism in the installation cavity from being contaminated with oil stains and thus reducing the heating efficiency. On the other hand, since the oil stains are accumulated on the baffle mechanism, when the user needs to clean the upper movement device later, he only needs to clean the oil stains on the baffle mechanism, which reduces the difficulty of cleaning the oil stains.

[0008] In addition, the upper movement device also includes an air circulation mechanism, and the first impeller of the air circulation mechanism is arranged on the side of the baffle mechanism away from the installation cavity, that is, when the upper movement device covers the pot body, the first impeller is located in the cooking cavity. Therefore, when the first impeller rotates, the heat energy generated by the heating mechanism can be converted into hot air in the cooking cavity, thereby accelerating the air circulation speed in the cooking cavity and improving the cooking efficiency of the food in the cooking cavity.

[0020] In order 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 in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0021] See also Figure 1 and Figure 2 , the embodiment of the present application provides an upper movement device 100 and a cooking utensil 200 equipped with the upper movement device 100. The cooking utensil 200 is a cooking utensil that can use heat to fry food. When it is working, the cooking utensil 200 can generate hot air through the heating tube in the pot body, and then use the fan to blow the high-temperature air into the pot to heat the food, so that the hot air can circulate in the pot body, thereby dehydrating the food to achieve the effect of frying food. In this embodiment, the cooking utensil 200 may include a pot body 210 and an upper movement device 100, wherein the pot body 210 is provided with a cooking cavity 2100, and the cooking cavity 2100 is used to place the food to be cooked. The upper movement device 100 covers the cooking cavity 2100 on the pot body 210 and is used to heat the food in 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, fry, etc. the food in the cooking cavity 2100.

[0023] In some possible embodiments, the cooking utensil 200 is a clamshell cooking utensil, and one side of the upper movement device 100 can be rotatably connected to the pot body 210. When the user needs to clean the upper movement device 100, the cleaning work can be completed by simply flipping the upper movement device 100. In other possible embodiments, the cooking utensil 200 is a pull-out type, and the upper movement device 100 is formed as the upper movement of the cooking utensil, and is integrally connected or assembled with the outer shell structure of the pot body. Specifically, the cooking utensil 200 can be an air fryer (for example, a clamshell air fryer, a pull-out air fryer), an air oven, etc., and this embodiment does not specifically limit this.

[0024] See also Figures 2 to 4 , the upper movement device 100 includes a cover assembly 120, a heating mechanism 140, a baffle mechanism 160 and an air circulation mechanism 180. Among them, the cover assembly 120 is provided with an installation cavity 1200, and the installation cavity 1200 forms an opening 1210 on one side of the cover assembly 120. When the cover assembly 120 covers the pot body 210, the opening 1210 faces the cooking cavity 2100. The heating mechanism 140 is arranged in the installation cavity 1200. The baffle mechanism 160 is arranged in the installation cavity 1200 and covers the opening 1210 to isolate the installation cavity 1200 from the cooking cavity 2100. Therefore, the upper movement device 100 provided in the present application can, on the one hand, prevent the heating mechanism 140 in the installation cavity 1200 from being contaminated with oil and thus reduce the heating efficiency. On the other hand, since the oil is accumulated on the baffle mechanism 160, when the user needs to clean the upper movement device 100 later, he only needs to clean the oil on the baffle mechanism 160, which reduces the difficulty of cleaning the oil. In addition, after the heating mechanism 140 transfers the heat to the baffle mechanism 160 , the entire baffle mechanism 160 acts as a heat source, and the heat radiated downward by the baffle mechanism 160 is more uniform, which effectively improves the cooking effect of the cooking appliance 200 .

[0025] The air circulation mechanism 180 includes a driving member 1800 and a first impeller 1810. The driving member 1800 is disposed on the cover assembly 120. The first impeller 1810 is disposed on the side of the baffle mechanism 160 away from the installation cavity 1200 and is connected to the driving member 1800. Therefore, when the upper movement device 100 covers the pot body 210, the first impeller 1810 is located in the cooking cavity 2100. When the first impeller 1810 rotates under the drive of the driving member 1800, the heat energy generated by the heating mechanism 140 can be converted 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. In addition, when the cooking utensil 200 realizes the function of cooking, the air circulation mechanism 180 can not only play a role in making the heat transfer more uniform, but also play a role in breaking bubbles, preventing excessive bubbles from overflowing after the food is boiled, so as to ensure that the cooking utensil 200 is more hygienic.

[0026] The various mechanisms in the upper movement device 100 are described in detail below.

[0027] See also Figure 6 and Figure 7 The cover assembly 120 may include a mounting shell 1230, and the mounting shell 1230 is used to connect the pot body 210. In some possible embodiments, the pot body 210 may include a connecting piece, and the mounting shell 1230 may include a matching piece matching the connecting piece, and the mounting shell 1230 may be movably connected to the pot body 210 through the matching connection between the connecting piece and the matching piece, or the mounting shell 1230 may be detachably connected to the pot body 210.

[0028] In this embodiment, the mounting shell 1230 may include a bracket portion 1232 and a surrounding portion 1234. The bracket portion 1232 is disposed above the pot body 210 and is fixedly connected to the surrounding portion 1234. The bracket portion 1232 is provided with the above-mentioned mounting cavity 1200, and the mounting cavity 1200 forms an opening 1210 on one side of the bracket portion 1232, that is, the opening 1210 of the mounting cavity 1200 is defined and formed by the bracket portion 1232. The bracket portion 1232 is also used to fix the driving member 1800 on the air circulation mechanism 180. Specifically, the bracket portion 1232 may be provided with a fixing groove, and the driving member 1800 is installed on the bracket portion 1232 through the fixing groove.

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

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

[0031] In some possible embodiments, the heating element 1400 may include a metal tube 1401, which is disposed in the installation 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., a carbon steel tube, a titanium tube, a stainless steel tube, a copper tube), which has the characteristics of fast heating rate, small thermal hysteresis, uniform heating, long heat radiation transmission distance, and fast heat exchange speed. In some possible embodiments, the heating element 1400 may include a carbon tube 1403, which is disposed in the installation cavity 1200. Specifically, the carbon tube 1403 is a heating device using carbon fiber as a heat transfer body, which has the characteristics of long service life and high electric heat conversion efficiency. In some possible embodiments, the heating element 1400 may include an infrared tube 1405, which is disposed in the installation cavity 1200. Specifically, the infrared tube 1405 is a tubular heater made using the infrared principle, 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, which is disposed in 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 has the characteristics of high heating efficiency and high heating rate.

[0032] In some other possible embodiments, the heating element 1400 may include a heating array film circuit (not shown in the figure), and the heating array film circuit is integrated in the baffle mechanism 160. The heating array film circuit is a circuit formed by mixing superconducting ceramic material powder and organic adhesive solvent into a paste slurry, and printing the slurry in the form of circuit wiring or pattern on a substrate material using screen printing technology, and has the characteristics of high power density, fast heating speed, high working temperature, fast heating rate, and uniform heating temperature field. Specifically, the heating array film circuit can be integrated on the side of the baffle mechanism 160 facing the installation cavity 1200, or on the side of the baffle mechanism 160 away from the installation cavity 1200, and this embodiment does not specifically limit this. It should be noted here that the heating array film circuit "integrated in" the baffle mechanism 160 can be that the heating array film circuit covers or adheres to the surface of the baffle mechanism 160; or the baffle mechanism 160 is used as the substrate material of the heating array film circuit, and the heating array film circuit is directly printed on the surface of the baffle mechanism 160.

[0033] In the present embodiment, the heating mechanism 140 may further include a heat insulating member 1410, which is disposed in the installation cavity 1200 and is used to isolate the heat generated by the heating mechanism 140 from the outside of the upper movement device 100, so as to prevent the user from accidentally touching the upper movement device 100 and causing burns. Specifically, the heat insulating member 1410 is disposed in the bracket portion 1232 and is located on the side of the heating member 1400 that is away from the cooking cavity 2100, so as to isolate the heat generated by the heating member 1400. In the present embodiment, the heat insulating member 1410 is located between the heating member 1400 and the driving member 1800. When the heating member 1400 is in working condition, the heat insulating member 1410 can reduce the influence of the heat generated by the heating member 1400 on the driving member 1800, thereby ensuring the service life of the driving member 1800. Figure 4 In the illustrated embodiment, the heat insulating member 1410 is generally in a shell-like structure, and a heat insulating cavity 1412 is provided on the side facing the opening 1210, the heating member 1400 is arranged in the heat insulating cavity 1412, and the baffle mechanism 160 covers the opening of the heat insulating cavity 1412. Therefore, the heat generated by the heating member 1400 will be introduced into the cooking cavity 2100 through the baffle mechanism 160 under the isolation of the heat insulating member 1410, thereby improving the heat utilization efficiency of the upper movement device 100. Specifically, the heat insulating member 1410 can be made of heat insulating materials such as ceramics, glass fiber, asbestos, rock wool, silicate, etc., which is not limited in this embodiment. In some possible embodiments, a heat insulating coating can be applied on the inner surface of the heat insulating member 1410, that is, on the side of the heat insulating member 1410 facing the heating member 1400, to improve the heat insulating effect of the heat insulating member 1410. Specifically, the heat insulating coating can be a heat insulating coating containing rare earth elements.

[0034] In this embodiment, the heating mechanism 140 may further include a high temperature protection member 1420. Specifically, the high temperature protection member 1420 may be a heat insulating mica sheet. The heat insulating mica sheet 1420 is a heat insulating material made of polysilicon muscovite, quartz, and the like. The heat insulating mica sheet 1420 may be disposed between the heat insulating member 1410 and the heating member 1400. For details, please refer to Figure 5 The heat-insulating mica sheet 1420 can be attached to the side of the heat-insulating element 1410 facing the heating element 1400 to further block the heat radiated by the heating element 1400 to the side of the heat-insulating element 1410, so as to ensure the service life of the driving element 1800. In other possible embodiments, the heat-insulating mica sheet 1420 can also be arranged on the side of the heat-insulating element 1410 away from the heating element to improve the heat-blocking effect.

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

[0036] In this embodiment, the heating mechanism 140 may further include a reflector 1430, which is disposed between the heat insulating 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 in the heat insulating 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 in 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 under the reflection of the reflector 1430, thereby improving the heating efficiency of the upper movement 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, thereby improving the heat reflection efficiency of the reflector 1430.

[0037] See also Figure 8 In some embodiments, the reflector 1430 may include a peripheral wall 1436 and a reflective boss 1438, and the two have a smooth transition. 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 approximately located in the middle of the reflector 1430, the bottom wall 1434 is connected between the peripheral wall 1436 and the reflective boss 1438, and 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 of a metal sheet. The heating element 1400 in this embodiment 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 above-mentioned tubular heating element is arranged around the outer periphery of the reflecting boss 1438 and is spaced apart from the reflecting boss 1438, that is, the above-mentioned tubular heating element is arranged between the reflecting boss 1438 and the surrounding wall 1436.

[0038] Specifically, the reflecting boss 1438 is roughly in the shape of a truncated cone, for example, the surface of the reflecting boss 1438 is a conical surface, so when the heat generated by the tubular heating element is radiated to the surface of the reflecting boss 1438, the reflecting boss 1438 will reflect the heat outward to the baffle mechanism 160. By providing the reflecting boss 1438, the present embodiment can increase the surface area of ​​the reflecting member 1430, thereby improving the heat reflection efficiency of the reflecting member 1430. In addition, the bottom wall 1434 and the baffle mechanism 160 are roughly 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 the heat generated by the tubular heating element is radiated to the peripheral wall 1436, the peripheral wall 1436 will reflect the heat inward to the baffle mechanism 160 to avoid the occurrence of a heat radiation dead angle.

[0039] In some possible embodiments, the reflector 1430 may be made of a heat-insulating material such as ceramics, and a heat-reflecting layer may 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 isolating the heat. Specifically, the heat-reflecting layer may be a metal oxide coating sprayed on the surface of the reflector 1430, or may be a reflective film (e.g., an aluminum-plated film, an aluminum-plated polyester film, an aluminum-plated polyimide film, etc.) attached to the surface of the reflector 1430. Therefore, when the upper movement device 100 is provided with the above-mentioned reflector 1430, it is not necessary to provide the heat-insulating member 1410, thereby saving the material cost of the upper movement device 100 and making the structure of the upper movement device 100 more compact. In other possible embodiments, the heating element 1400 may be a heating array film circuit. Since the heating array film circuit is directly integrated on the baffle mechanism 160, it is not necessary to set the reflector 1430 in the upper movement device 100, thereby saving the material cost of the upper movement device 100 and making the structure of the upper movement device 100 more compact.

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

[0041] In some possible embodiments, the baffle bracket 1610 may be fixed around the outer circumference of the heat-conducting baffle 1600 and fixedly connected to the mounting shell 1230, that is, the heat-conducting baffle 1600 is connected to the mounting shell 1230 through the baffle bracket 1610, and the baffle bracket 1610 together covers the opening 1210. Therefore, during the use of the cooking utensil 200 provided with the upper movement device 100, the oil stains in the cooking cavity 2100 are blocked by the heat-conducting baffle 1600 and the baffle bracket 1610, and cannot enter the mounting cavity 1200, thereby preventing the components (e.g., the heating element 1400, the heat insulating element 1410, etc.) in the mounting cavity 1200 from being stained with oil stains. When the user needs to clean the upper movement device 100 later, it is only necessary to clean the oil stains on the heat-conducting baffle 1600 and the baffle bracket 1610, which reduces the difficulty of cleaning the oil stains.

[0042] In some 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-insulating member 1410, so that the heat-conducting baffle 1600 may be connected to the heat-insulating member 1410 through the baffle bracket 1610. The heat-conducting baffle 1600 may prevent oil stains from entering the heat-insulating cavity 1412, thereby preventing the components (e.g., the heating member 1400) in the heat-insulating cavity 1412 from being contaminated with oil stains, thereby reducing the difficulty of cleaning the oil stains later.

[0043] See also Fig. 9 The baffle support 1610 is generally annular in structure, and may include a main body 1612, a first bearing part 1614, and a second bearing part 1616, wherein the main body 1612 is generally annular in shape, the first bearing part 1614 is connected to one side (also called the inner side) of the main body 1612, and extends in the direction where the heat conduction baffle 1600 is located; the second bearing part 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 conduction baffle 1600. As an example, the main body 1612, the first bearing part 1614, and the second bearing part 1616 may be an integrally formed structure, for example, formed by stamping a metal plate.

[0044] The plane where the main body 1612 is located is substantially parallel to or coplanar with the plane where the heat-conducting baffle 1600 is located, and the main body 1612 is used to carry the reflector 1430 and the heat-insulating member 1410. Specifically, the reflector 1430 may further include a first flange portion 1439, which is connected to an end of the peripheral wall 1436 of the reflector 1430 away from the bottom wall 1434 and extends radially in a direction away from the reflective cavity 1432. The reflector 1430 is superimposed on the main body 1612 through the first flange portion 1439.

[0045] Further, the heat insulating member 1410 may be stacked on the first flange portion 1439, so as to fix the first flange portion 1439 of the reflector 1430 together with the main body 1612, so as to improve the integration of the heating mechanism 140. Specifically, the heat insulating member 1410 may include a body 1414 and a second flange portion 1416, the body 1414 is used to form the above-mentioned heat insulating cavity 1412, the heat insulating cavity 1412 is arranged on a side of the body 1414 facing the opening 1210, and the second flange portion 1416 is connected to the lip of the body 1414 and extends radially in a direction away from the heat insulating cavity 1412. When the reflective component 1430 is stacked on the main body 1612, the heat insulating component 1410 is stacked on the first flange portion 1439 of the reflective component 1430 through the second flange portion 1416, so that the first flange portion 1439 is located between the second flange portion 1416 and the main body 1612. The three can be fixed by adhesive bonding, threaded fasteners, etc., and can also be fixed by mechanical clips or slots.

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

[0047] The second bearing portion 1616 is connected to the outer edge of the main body 1612 and is bent relative to the main body 1612, so that the second bearing portion 1616 is axially offset relative to the main body 1612, so that the connection structure between the second bearing portion 1616 and the main body 1612 is roughly stepped, so that the second bearing portion 1616 can be used to bear the protective baffle 1630 and limit the protective baffle 1630. Specifically, the second bearing portion 1616 and the second flange portion 1416 of the heat insulation element jointly define a bearing space, and a part of the structure of the protective baffle 1630 can be inserted into the bearing space. Specifically, the second bearing portion 1616 and the second flange portion 1416 of the thermal insulation component are arranged relative to each other in the axial direction, and the edge portion of the protective baffle 1630 can be overlapped 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, threaded fasteners, etc., or clamped and fixed by mechanical clips or slots.

[0048] In this embodiment, the reflector 1430, the heat insulating member 1410, the heat conducting baffle 1600 and the protective baffle 1630 are assembled together by the baffle bracket 1610 to form an integral module, so that the structure of the upper movement device 100 is more compact and convenient for assembly and disassembly. Specifically, when disassembling the upper movement device 100, as long as the baffle bracket 1610 is disassembled first, the heat conducting baffle 1600, the protective baffle 1630, the reflector 1430 and the heat insulating member 1410 can be disassembled in sequence, so as to facilitate the cleaning of the heat conducting baffle 1600 and the baffle bracket 1610, and the replacement of the reflector 1430 and the heat insulating member 1410.

[0049] In some possible embodiments, the area of ​​the heat conductive baffle 1600 is almost the same as the projected area of ​​the opening 1210 on the installation cavity 1200. In this case, the baffle bracket 1610 is no longer required in the upper movement device 100, thereby saving the material cost of the upper movement device 100.

[0050] In this embodiment, the baffle mechanism 160 may further include a protective baffle 1630. Figure 6 and Figure 7 The protective baffle 1630 is disposed between the bracket portion 1232 and the surrounding portion 1234. When the cover assembly 120 covers the pot body 210, the protective baffle 1630 and the heat-conducting baffle 1600 jointly 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.). Therefore, when cooking food in the cooking cavity 2100, the user can observe the cooking status of the food through the protective baffle 1630, thereby reducing the probability of the food being burnt. Specifically, when the heat conductive baffle 1600 closes the opening 1210 of the mounting cavity 1200 on the bracket portion 1232 through the baffle bracket 1610, one end of the protective baffle 1630 can be pressed onto the second supporting portion 1616 of the baffle bracket 1610, and the other end is connected to the surrounding portion 1234, that is, the protective baffle 1630, the heat conductive baffle 1600 and the baffle bracket 1610 jointly cover the opening of the cooking cavity 2100.

[0051] In this embodiment, the baffle mechanism 160 may further include a fixing ring 1650, which is used to cover the pot body 210. Specifically, the fixing ring 1650 is generally annular, which is arranged around the outer periphery of the protective baffle 1630 and is fixedly connected to the surrounding portion 1234, that is, the mounting shell 1230 is connected to the pot body 210 through the fixing ring 1650. Please refer to Figure 4 , Figure 6 and Fig.10The surrounding portion 1234 is provided with a first vent hole 1236, and the fixing ring 1650 is provided with a second vent hole 1651 connected with the first vent hole 1236. When the upper movement device 100 covers the pot body 210, the first vent hole 1236 connects the cooking cavity 2100 with the outside through the second vent hole 1651. Therefore, when the cooking utensil 200 is in the working state, the hot air in the cooking cavity 2100 can be discharged through the first vent hole 1236 and the second vent hole 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 driving member 1800 and a first impeller 1810, and the driving member 1800 is disposed on the cover assembly 120. Specifically, the driving member 1800 may be a rotary driving member, for example, a rotary motor with a reduction gearbox, or a rotary driving device such as a rotary steering gear or a rotary cylinder.

[0053] The first impeller 1810 is disposed on a side of the baffle mechanism 160 away from the installation cavity 1200, and is connected to the driving member 1800. When the first impeller 1810 is driven by the driving member 1800 to rotate, 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 a quadrilateral shape, a vine leaf shape, a wing shape, etc., and the number of the 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 driving member 1800. On the one hand, after the first impeller 1810 is disassembled, the baffle mechanism 160 exposes a larger cleanable area, which improves the convenience of cleaning; on the other hand, after the first impeller 1810 is disassembled, it is easier to clean the impeller separately. In addition, when the first impeller 1810 is not needed, it can be disassembled and stored separately to increase the service life of the first impeller 1810.

[0055] In this example, please refer again to Figure 4 The air circulation mechanism 180 further includes an output shaft 1830 and a second impeller 1850. The output shaft 1830 is disposed through the cover assembly 120, one end of the output shaft 1830 is connected to the driving member 1800, and the other end is connected to the first impeller 1810, that is, the driving member 1800 drives the first impeller 1810 to rotate through 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. The second impeller 1830 and the first impeller 1810 are respectively disposed on opposite sides of the baffle mechanism 160. Figure 4 In the embodiment, the second impeller 1850 is arranged away from the opening of the heat insulation cavity 1420 and is located between the heat insulation member 1410 and the driving member 1800. Therefore, when the driving member 1800 drives the second impeller 1850 to rotate through the output shaft 1830, the heat between the heat insulation member 1410 and the driving member 1800 can be reduced, and the heat dissipation effect of the driving member 1800 is achieved, thereby ensuring the service life of the driving member 1800. Specifically, the shape of the blades in the second impeller 1850 can be a quadrilateral, a vine leaf, a wing shape, etc., and the number of blades can be 3, 5, 7, etc. The shape of the second impeller 1850 can be the same as that of the first impeller 1810, or it can be different, and this embodiment does not limit this.

[0057] The present embodiment provides an upper movement device 100, wherein the upper movement 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 is provided with an installation cavity 1200, and the installation cavity 1200 forms an opening 1210 on one side of the cover assembly 120. When the cover assembly 120 covers the pot body 210, the opening 1210 faces the cooking cavity 2100. The heating mechanism 140 is disposed in the installation cavity 1200. The baffle mechanism 160 is disposed in the installation cavity 1200 and covers the opening 1210 to isolate the installation cavity 1200 from the cooking cavity 2100. Therefore, the upper movement device 100 provided in the present application can, on the one hand, avoid the problem that the heating mechanism 140 in the installation cavity 1200 is contaminated with oil and thus reduces the heating efficiency. On the other hand, since the oil stains are accumulated on the baffle mechanism 160 , when the user needs to clean the upper movement device 100 later, he only needs to clean the oil stains on the baffle mechanism 160 , which reduces the difficulty of cleaning the oil stains.

[0058] In addition, the air circulation mechanism 180 includes a driving member 1800 and a first impeller 1810. The driving member 1800 is arranged on the cover assembly 120. The first impeller 1810 is arranged on the side of the baffle mechanism 160 away from the installation cavity 1200 and connected to the driving member 1800. Therefore, when the upper movement device 100 covers the pot body 210, the first impeller 1810 is located in the cooking cavity 2100. When the first impeller 1810 rotates under the drive of the driving 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. In addition, when the cooking utensil 200 realizes the function of cooking, the air circulation mechanism 180 can not only play a role in making the heat transfer more uniform, but also play a role in breaking bubbles, preventing excessive bubbles from overflowing after the food is boiled, so as to ensure that the cooking utensil 200 is more hygienic.
