Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a cooking appliance. Background Technology

[0002] The microwave-steam-grill combo combines steaming, grilling, and microwave functions, making it a popular household kitchen appliance. By using one appliance to perform multiple functions, it reduces space usage and makes cooking more convenient.

[0003] In related technologies, a microwave-steam-oven combo requires both a heating fan module and a microwave module. The heating fan assembly is installed and removed separately from the rear of the combo's inner cavity. A through-hole needs to be made in the inner cavity for the motor shaft of the heating fan assembly to pass through, connecting to the internal fan blades to blow hot air forward. Because the combo needs to perform both steaming and microwave cooking functions, the through-hole in the inner cavity needs to be sealed.

[0004] However, the inner cavity of current microwave-steam-grill combos has poor sealing reliability, making them prone to steam and microwave leakage. Utility Model Content

[0005] This application provides a cooking appliance to solve the technical problem of poor sealing reliability of the inner pot of current microwave-steam-grill combination appliances, which easily leads to steam and microwave leakage.

[0006] This application provides a cooking appliance, the cooking appliance comprising:

[0007] Inner pot, the inner pot having a cooking cavity;

[0008] A microwave module is disposed outside the inner liner;

[0009] The functional module includes a functional component and a support. The support is disposed outside the inner pot and connected to the inner pot. The functional component is connected to the support. The inner pot has a through hole, and a portion of the functional component passes through the through hole and is inserted into the cooking cavity.

[0010] A shielding component, which abuts against the outer wall of the inner liner and is arranged around the through hole;

[0011] Multiple seals are arranged concentrically and at intervals around the through hole on the outside of the inner liner, and the shield is located between adjacent seals;

[0012] The bracket abuts against the side of the seal opposite to the inner liner, and the bracket has a protrusion facing the inner liner. The protrusion is located between adjacent seals and contacts the shielding element to shield microwaves.

[0013] The cooking appliance provided in this application simultaneously sets up shielding and sealing components around the through hole to respectively shield microwaves and seal steam. Multiple sealing and shielding components are alternately spaced, which not only ensures good microwave shielding effect, but also forms a multi-layer steam sealing structure to better prevent steam leakage.

[0014] As an optional implementation, the shield is annular, and the spacing between adjacent seals matches the width of the shield.

[0015] With this configuration, the seal can limit the position of the shield, preventing the shield from shifting and creating gaps that could cause microwave leakage.

[0016] As an optional implementation, the protrusion is coaxially arranged around the through hole and the shielding member; or, there are multiple protrusions, which are arranged sequentially at intervals around the through hole, and all of the multiple protrusions abut against the shielding member.

[0017] This design ensures that the shielding component fits snugly against the inner liner all around its circumference.

[0018] As an optional implementation, the protrusion includes a first annular boss and a second annular boss, the first annular boss and the second annular boss being coaxially spaced around the through hole, and both the first annular boss and the second annular boss abutting against the shielding member.

[0019] This configuration can improve the reliability of the shielding components during installation.

[0020] As an optional implementation, the second annular boss is located outside the first annular boss; the second annular boss has a mating groove facing the top of the inner liner, and the end of the sealing member on the outside of the shield facing away from the inner liner is inserted into the mating groove; when the end face of the second annular boss facing the top of the inner liner contacts the shield, the bottom of the mating groove compresses the sealing member along the axial direction of the through hole.

[0021] This design allows the second annular boss to abut against the shielding component while compressing the sealing component, simplifying the assembly structure.

[0022] As an optional implementation, the inner side of the first annular boss has a stepped portion, which abuts against the end of the sealing member on the inner side of the shield that is away from the inner liner; when the end face of the first annular boss facing the top of the inner liner contacts the shield, the stepped portion compresses the sealing member along the axial direction of the through hole.

[0023] This design allows the first annular boss to abut against the shielding component while compressing the sealing component, simplifying the assembly structure.

[0024] As an optional implementation, the thickness of the seal located inside the shield is less than the thickness of the seal located outside the shield along the radial direction of the through hole.

[0025] This design ensures that the inner seal can be as close as possible to the inner edge of the through hole, while the outer seal can have a larger sealing width after being compressed, thus providing better steam sealing.

[0026] As an optional implementation, the functional component includes a motor and a fan blade. The motor is disposed outside the inner liner and connected to the bracket. The fan blade is disposed inside the cooking cavity. The output shaft of the motor passes through the through hole and is connected to the fan blade. There is a gap between the output shaft and the inner edge of the through hole.

[0027] The inner edge of the through hole is provided with a first limiting part, which is bent outward of the cooking cavity and abuts against the sealing member located inside the shielding member.

[0028] This design utilizes the motor's bracket to secure the shielding and sealing components, simplifying the assembly structure while improving the reliability of the sealing and shielding structure.

[0029] As an optional implementation, the cooking appliance further includes a mounting plate connected to the outer side wall of the inner pot. The mounting plate has an opening, and the circumferential edge of the opening has a second limiting portion that bends toward the inner pot. The second limiting portion is positioned outside the sealing member outside the shielding member.

[0030] This setting allows for radial positioning of the seal, preventing positional deviations or excessive deformation of the seal that could affect the steam sealing effect.

[0031] As an optional implementation, the outer wall of the inner liner has a recessed groove, the through hole is located in the recessed groove, the bottom of the recessed groove forms a sealing plane, and both the sealing element and the shielding element are located in the recessed groove and abut against the sealing plane.

[0032] This design allows for pre-positioning of functional modules, shielding components, and sealing components during assembly, improving assembly convenience.

[0033] The cooking appliance provided in this application includes an inner pot, a microwave module, a functional module, a shield, and multiple seals. The inner pot has a cooking cavity. The microwave module is located outside the inner pot. The functional module includes a functional component and a support. The support is located outside the inner pot and connected to it, and the functional component is connected to the support. The inner pot has a through hole, and a portion of the functional component passes through the through hole and is inserted into the cooking cavity. The shield abuts against the outer wall of the inner pot and is arranged around the through hole. Multiple seals are located on the outside of the inner pot, concentrically spaced around the through hole, with the shield located between adjacent seals. The support abuts against the side of the seal facing away from the inner pot. The support has a protrusion facing the inner pot, located between adjacent seals and in contact with the shield. This ensures good microwave shielding while forming a multi-layered steam sealing structure, better preventing steam leakage.

[0055] A microwave-steam-oven combo is a commonly used cooking appliance that integrates steaming, baking, and microwave functions. It requires both a heating fan module and a microwave module. The heating fan assembly is installed and removed separately from the rear of the combo's inner cavity. A through-hole needs to be made in the inner cavity for the motor shaft of the heating fan assembly to pass through, connecting to the internal fan blades to blow hot air forward. Because the combo needs to perform both steaming and microwave cooking functions, the through-hole in the inner cavity must be sealed. However, the sealing reliability of the inner cavity in current microwave-steam-oven combos is poor, easily leading to steam and microwave leaks. Furthermore, the complex assembly and sealing structure makes disassembly and cleaning of the heating fan assembly difficult, resulting in high costs and potential odors.

[0056] To address the aforementioned technical problems, this application provides a cooking appliance that achieves steam sealing and microwave shielding by incorporating sealing and shielding components, respectively. The sealing and shielding components are installed and positioned using a functional module's bracket, ensuring the shielding component fits snugly against the inner pot for effective microwave shielding. Multiple sealing components provide multi-layered steam sealing, preventing steam leakage. Compared to existing technologies, the cooking appliance of this application has a simpler overall sealing structure, is easier to assemble, and offers better microwave and steam shielding.

[0057] Figure 1 This is a schematic diagram of the structure of the cooking utensil provided in the embodiments of this application; Figure 2 This is a schematic diagram of the structure of the back side of the cooking utensil provided in the embodiments of this application; Figure 3 A cross-sectional view of the cooking utensil provided in the embodiments of this application; Figure 4 for Figure 3 A partial view of position A in the middle.

[0058] Reference Figures 1 to 4 As shown, this application embodiment provides a cooking appliance 10, including an inner pot 100 and a shell, the inner pot 100 being housed in the shell, and the inner pot 100 having a cooking cavity 101.

[0059] In this embodiment, the type of cooking appliance 10 is not limited. For example, the cooking appliance 10 can be a standalone countertop or cabinet-style cooking device, or an electrical appliance integrated with a gas stove or other appliances. In this embodiment, a microwave-steam-oven combo unit is used as an example for illustration.

[0060] A microwave-steam-oven combo combines the functions of a microwave, steamer, and oven, freeing up kitchen space as one appliance can function as multiple independent kitchen appliances. The steam-oven function works by heating water to create steam, which is then used to steam, bake, or cook food. It can also utilize heating elements to generate hot air for further heating. The microwave function works by causing water molecules in food to vibrate rapidly, generating heat through intermolecular friction.

[0061] It should be noted that the inner pot 100 is one of the core components of the steam oven, and it is used for cooking food. The material of the inner pot 100 is not limited. For example, the inner pot 100 can be made of stainless steel, which can withstand high temperatures of water and detergents, and also has antibacterial properties and is easy to clean; alternatively, the inner pot 100 can be made of ceramic, which has the advantages of being smooth, slow-deteriorating, and corrosion-resistant, and can also improve the cleaning effect. This embodiment does not limit this aspect.

[0062] In the embodiments of this application, reference is made to Figures 1 to 4 As shown, the cooking appliance 10 includes an inner pot 100, a microwave module 200, and a functional module 300.

[0063] The microwave module 200 is located outside the inner cavity 100 and is used to generate microwaves to heat food. The functional module 300 is located inside the inner cavity 100 and can be a module that realizes steaming and baking functions. For example, the functional module 300 can be a fan assembly used to blow air into the cooking cavity 101, which works with the heating module to heat the food with hot air.

[0064] In some embodiments, the functional module 300 includes a functional component 310 and a support 320. The support 320 is disposed outside the inner pot 100 and connected to the inner pot 100, and the functional component 310 is connected to the support 320. The inner pot 100 has a through hole 102, and a portion of the structure of the functional component 310 passes through the through hole 102 and is inserted into the cooking cavity 101.

[0065] Understandably, the bracket 320 serves to install and fix the functional component 310, while the through hole 102 avoids the functional component 310. The functional component 310 can be a fan assembly, with the fan blades located inside the inner liner 100 and the motor located outside the inner liner 100. The motor's output shaft passes through the through hole 102 and connects to the fan blades, thereby driving the fan blades to rotate and blow hot air into the food inside the inner liner 100.

[0066] Those skilled in the art will understand that, since the output shaft of the motor needs to rotate when the functional component 310 performs the function of the fan assembly, a gap is required between the output shaft of the motor and the through hole 102 to avoid interference. During cooking, both microwaves and steam may pass through the through hole 102 to the outside of the inner pot 100, thus a sealing structure needs to be designed.

[0067] Figure 5 Exploded views of functional modules, shielding components, and sealing components in the cooking appliance provided in the embodiments of this application; Figure 6 A cross-sectional view of the back side of the inner pot of a cooking appliance provided in an embodiment of this application; Figure 7 A cross-sectional view showing the connection of the support, shield, and seal in a cooking appliance provided in an embodiment of this application; Figure 8 A cross-sectional view of a functional module in a cooking appliance provided in an embodiment of this application.

[0068] Please refer to Figures 1 to 8 In some embodiments, the cooking appliance 10 provided in this application includes a shield 400 and a seal 500. The shield 400 and the seal 500 are located on the outside of the inner pot 100. The shield 400 abuts against the outer wall of the inner pot 100 and is disposed around the through hole 102. There are multiple seals 500, which are concentrically spaced around the through hole 102 on the outside of the inner pot 100.

[0069] The shielding element 400 is located between adjacent sealing elements 500. The bracket 320 abuts against the side of the sealing element 500 away from the inner liner 100. The bracket 320 has a protrusion 321 facing the inner liner 100. The protrusion 321 is located between adjacent sealing elements 500 and contacts the shielding element 400 to shield microwaves.

[0070] Understandably, the sealing element 500 has an annular structure, and each sealing ring can form a sealing structure around the through hole 102. Multiple sealing elements 500 arranged concentrically can form multiple sealing structures to prevent vapor leakage, while the shielding element 400 can utilize the space between adjacent sealing elements 500, be placed between two sealing elements 500, and also surround the through hole 102 to achieve a good microwave shielding effect.

[0071] Those skilled in the art will understand that microwaves are radio frequency electromagnetic waves within a specific frequency range. The principle of microwave shielding is to utilize the conductivity and / or magnetism of materials to reflect and absorb electromagnetic waves, thereby achieving shielding effectiveness. In this embodiment, the inner liner 100, the shielding component 400, and the support 320 are in sequential contact. All three components can be made of highly conductive materials, or materials with a certain conductivity and / or high magnetic permeability, to prevent microwaves from leaking from the through-hole 102 to the outside of the inner liner 100.

[0072] For example, part of the structure of the bracket 320 is in contact with the shield 400. The bracket 320, the inner liner 100 and the shield 400 can all be made of metal, so that the inner liner 100, the shield 400 and the bracket 320 can contact each other in sequence to achieve the microwave shielding effect.

[0073] It should be noted that in the cooking appliance 10 provided in this application embodiment, by simultaneously setting a shielding member 400 and a sealing member 500 around the through hole 102, the shielding member 400 and the sealing member 500 respectively serve to shield microwaves and seal steam. Multiple sealing members 500 and shielding members 400 are alternately spaced, which, while ensuring a good microwave shielding effect, forms a multi-layer steam sealing structure, thus better preventing steam leakage.

[0074] Furthermore, since both the sealing element 500 and the shielding element 400 are located on the outside of the inner liner 100, and are installed together with the bracket 320 of the functional module 300 into the inner liner 100, the overall sealing structure is simpler, with fewer assembly steps and easier assembly, which can reduce the product's manufacturing cost. Moreover, the sealing element 500 and the shielding element 400, located on the outside of the inner liner 100, are protected from the high humidity, high temperature, and oily environment of the inner liner 100, preventing corrosion of the sealing element 500 and the shielding element 400 and extending their service life.

[0075] In some embodiments, the shield 400 is annular, and the spacing between adjacent seals 500 matches the width dimension of the shield 400.

[0076] Understandably, the seal 500 in the inner ring has a smaller diameter, while the seal 500 in the outer ring has a larger diameter. The seal 500 in the inner ring can abut against the inner side of the shield 400, and the seal 500 in the outer ring can abut against the outer side of the shield 400. This allows the seal 500 to limit the movement of the shield 400, preventing displacement of the shield 400 and the resulting gap that could cause microwave leakage.

[0077] For example, the shielding element 400 can be a copper mesh. Both the bracket 320 and the inner liner 100 can be made of metal. One side of the shielding element 400 contacts the inner liner 100, and the other side contacts the bracket 320, thereby forming an effective microwave shielding structure.

[0078] For example, the seal 500 can be made of elastic materials such as rubber or silicone, and the seal 500 has certain high temperature resistance and corrosion resistance properties. When the bracket 320 abuts against the seal 500, the seal 500 can be compressed to a certain extent to improve the vapor sealing effect.

[0079] In some embodiments, the protrusion 321 surrounds the through hole 102 and is coaxially disposed with the shield 400.

[0080] In other embodiments, there may be multiple protrusions 321, which are arranged sequentially and at intervals around the through hole 102, and all of the multiple protrusions 321 abut against the shield 400.

[0081] It should be noted that whether it is a single protrusion 321 arranged in a ring or multiple protrusions 321 arranged in a ring, they can press the shield 400 tightly in the circumference of the shield 400, ensuring that the shield 400 is tightly attached to the inner liner 100 in the circumference.

[0082] In one possible implementation, the protrusion 321 may include a first annular protrusion 3211 and a second annular protrusion 3212. The first annular protrusion 3211 and the second annular protrusion 3212 are coaxially spaced around the through hole 102. Both the first annular protrusion 3211 and the second annular protrusion 3212 abut against the shield 400, which can improve the installation reliability of the shield 400.

[0083] It is understandable that one of the first annular boss 3211 and the second annular boss 3212 has a relatively small diameter and the other has a relatively large diameter. The two are axially spaced around the through hole 102, one forming an inner ring and the other forming an outer ring. The smaller diameter of the first annular boss 3211 and the second annular boss 3212 can press against the inner edge of the shield 400 in the inner ring, while the larger diameter of the first annular boss 3211 and the second annular boss 3212 can press against the outer edge of the shield 400 in the outer ring.

[0084] In some embodiments, the second annular boss 3212 is located outside the first annular boss 3211. That is, the diameter of the second annular boss 3212 is larger than the diameter of the first annular boss 3211.

[0085] The second annular boss 3212 has a mating groove 3213 facing the top of the inner liner 100, and the sealing member 500 on the outside of the shield 400 is inserted into the mating groove 3213 at the end facing away from the inner liner 100.

[0086] Understandably, when the end face of the second annular boss 3212 facing the top of the inner liner 100 contacts the shield 400, the bottom of the mating groove 3213 compresses the sealing member 500 along the axial direction of the through hole 102. In this way, the sealing member 500 can be compressed while the second annular boss 3212 abuts against the shield 400, simplifying the assembly structure.

[0087] For example, the inner side of the first annular boss 3211 has a stepped portion 3214, which abuts against the end of the sealing member 500 on the inner side of the shield 400 away from the inner liner 100. When the end face of the first annular boss 3211 facing the top of the inner liner 100 contacts the shield 400, the stepped portion 3214 compresses the sealing member 500 along the axial direction of the through hole 102.

[0088] For example, the first annular boss 3211 and the second annular boss 3212 can be integrally formed structures on the bracket 320. The seal 500 and the shield 400 can be assembled with one end of the first annular boss 3211 and the second annular boss 3212 along the axial direction of the bracket 320. After assembly, the seal 500 and the shield 400 can be installed on the inner liner 100 as a whole with the functional module 300, so that the shield 400 and the seal 500 are pressed together along the axial direction of the through hole 102.

[0089] In some embodiments, along the radial direction of the through hole 102, the thickness of the seal 500 located inside the shield 400 is less than the thickness of the seal 500 located outside the shield 400, thereby ensuring that the inner seal 500 can be as close as possible to the inner edge of the through hole 102, while the outer seal 500 can have a larger sealing width after being compressed, thus having better vapor sealing performance.

[0090] It should be noted that along the axial direction of the through hole 102, the height of the shield 400 is less than the height of the seal 500, so as to ensure that the seal 500 has a certain amount of compressibility to ensure a good sealing effect.

[0091] The following section uses functional module 300 as an example of a fan component to explain in detail the structure and installation method of functional module 300.

[0092] Figure 9 This is a schematic diagram of the interior of the cooking cavity in the cooking appliance provided in the embodiments of this application; Figure 10 A cross-sectional view of the back side of a cooking utensil provided in an embodiment of this application; Figure 11 This is a schematic diagram of the fan cover in the cooking appliance provided in the embodiments of this application after disassembly; Figure 12 This is a schematic diagram of the structure of the fan cover in the cooking appliance provided in the embodiments of this application.

[0093] Please refer to Figures 1 to 12 In one possible implementation, the functional component 310 may include a motor 311 and a fan blade 313. The motor 311 is disposed outside the inner liner 100 and is connected to the bracket 320. The fan blade 313 is disposed inside the cooking cavity 101. The output shaft 312 of the motor 311 passes through the through hole 102 and is connected to the fan blade 313. There is a gap between the output shaft 312 and the inner edge of the through hole 102.

[0094] Understandably, the bracket 320 serves both to mount and fix the motor 311, and to fix the seal 500 and the shield 400. By using the bracket 320 of the motor 311 to fix the shield 400 and the seal 500, the assembly structure is simplified while the reliability of the sealing and shielding structure is improved.

[0095] In some embodiments, the cooking appliance 10 may further include a fan cover 110, which covers the side of the fan blade 313 facing the inside of the cooking cavity 101. The fan cover 110 is connected to the inner liner 100 by a threaded fastener 120. The fan cover 110 is provided with a boss 130 facing the inside of the cooking cavity 101 at the position where the threaded fastener 120 is connected. The boss 130 abuts against the inner wall of the cooking cavity 101 so that there is a gap between the fan cover 110 and the inner wall of the cooking cavity 101.

[0096] Understandably, the fan cover 110 protects the fan blades 313 and blocks the through hole 102 behind the fan blades 313. The fan cover 110 can be removed by unscrewing the threaded fasteners 120, making it easy to clean the fan blades 313 and the side walls of the cooking cavity 101.

[0097] For example, the gap size is greater than or equal to 3mm, including but not limited to 3mm, 3.1mm, 4mm, 5mm, etc., and this application embodiment does not specifically limit it. By controlling the distance between the fan cover 110 and the inner wall of the inner liner 100 within a reasonable range, arcing between the fan cover 110 and the inner liner 100 can be avoided.

[0098] For example, there can be four bosses 130, which are respectively located at the four corners of the rear sidewall inside the cooking cavity 101. The shape of the fan cover 110 can match the shape of the rear sidewall of the cooking cavity 101, and the four corners of the fan cover 110 are respectively connected to the four bosses 130. Multiple ventilation holes can be provided on the fan cover 110 so that the airflow generated by the fan blades 313 can pass through the fan cover 110 and flow to the front of the cooking cavity 101.

[0099] In some embodiments, the cooking appliance 10 may further include a shielding sleeve 314 and a shaft sealing ring 315. The shielding sleeve 314 may be fitted onto the output shaft 312 and is located between the output shaft 312 and the bracket 320. The shaft sealing ring 315 is fitted onto the output shaft 312, and the inner wall of the shaft sealing ring 315 abuts against the outer wall of the output shaft 312, while the outer wall of the shaft sealing ring 315 abuts against the bracket 320, thereby preventing microwave and steam leakage between the output shaft 312 of the motor 311 and the bracket 320.

[0100] Understandably, the sealing ring can be made of materials such as rubber or silicone. A dynamic seal is established between the output shaft 312 and the rotating shaft sealing ring 315. The shielding sleeve 314 can be a copper sleeve. The shielding sleeve 314 can be located behind the sealing ring along the axial direction of the output shaft 312.

[0101] In some embodiments, the inner edge of the through hole 102 is provided with a first limiting part 103, the first limiting part 103 is bent toward the outside of the cooking cavity 101, and the first limiting part 103 abuts against the sealing member 500 located inside the shield 400.

[0102] For example, the first limiting part 103 can be a flange structure circumferentially connected to the through hole 102.

[0103] In some embodiments, the cooking appliance 10 may further include a mounting plate 150 connected to the outer side wall of the inner pot 100. The mounting plate 150 has an opening, and the circumferential edge of the opening has a second limiting portion 151 bent toward the inner pot 100. The second limiting portion 151 is positioned on the outside of the sealing member 500 outside the shield 400, thereby radially limiting the installation position of the sealing member 500 and avoiding positional deviation or excessive deformation of the sealing member 500 that would affect the steam sealing effect.

[0104] For example, the second limiting part 151 may be a flange structure in the circumferential direction of the inner edge of the opening of the mounting plate 150.

[0105] As an optional implementation, the outer wall of the inner liner 100 has a recessed groove 104, the through hole 102 is located in the recessed groove 104, the bottom of the recessed groove 104 forms a sealing plane, and the sealing member 500 and the shielding member 400 are both located in the recessed groove 104 and abut against the sealing plane.

[0106] Understandably, during assembly, the recessed platform 104 can pre-position the functional module 300, shielding component 400, and sealing component 500, thereby improving the convenience of assembly.

[0107] In some embodiments, the cooking appliance 10 may further include a connector 140, a first fastener 141, and a second fastener 142. The connector 140 passes sequentially through the side wall of the inner pot 100, the mounting plate 150, and the bracket 320320 from inside the cooking cavity 101. The first fastener 141 is sleeved on the connector 140 and supported between the outer wall of the inner pot 100 and the mounting plate 150. The second fastener 142 is located on the side of the bracket 320320 away from the mounting plate 150 and is locked to the connector 140, thereby improving the installation reliability of the bracket 320320.

[0108] When understood, the connector 140 can be a bolt, and both the first fastener 141 and the second fastener 142 can be nuts. The first fastener 141 can be screwed onto the connector 140. During assembly, the connector 140 can be fixed to the inner liner 100 first using the first fastener 141, then the mounting plate 150 can be installed onto the connector 140, and the mounting plate 150 can be fixed by screwing the second fastener 142 onto the connector 140.

[0109] It should be noted that a heating tube surrounding the fan blade 313 can be installed inside the cooking cavity 101 to generate heat, causing the fan blade 313 to rotate and generate hot air. The microwave module 200 can be installed on the top of the inner pot, or part of the structure can be installed on the back side of the inner pot and part of the structure can be installed on the top of the inner pot. The specific structure and installation position of the microwave structure are not limited in this embodiment.

[0110] The cooking appliance provided in this application includes an inner pot, a microwave module, a functional module, a shield, and multiple seals. The inner pot has a cooking cavity. The microwave module is located outside the inner pot. The functional module includes a functional component and a support. The support is located outside the inner pot and connected to it, and the functional component is connected to the support. The inner pot has a through hole, and a portion of the functional component passes through the through hole and is inserted into the cooking cavity. The shield abuts against the outer wall of the inner pot and is arranged around the through hole. Multiple seals are located on the outside of the inner pot, concentrically spaced around the through hole, with the shield located between adjacent seals. The support abuts against the side of the seal facing away from the inner pot. The support has a protrusion facing the inner pot, located between adjacent seals and in contact with the shield. This ensures good microwave shielding while forming a multi-layered steam sealing structure, better preventing steam leakage.
