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, microwave-steam-oven combos require the simultaneous installation of 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 microwave cooking, a shielding structure needs to be installed at the through-hole in the inner cavity for microwave shielding.

[0004] However, the inner cavity of current microwave-steam-grill combo ovens has poor sealing reliability, and the shielding components are prone to gaps with the inner cavity, causing microwave leakage. Utility Model Content

[0005] This application provides a cooking appliance to solve the technical problems of poor sealing reliability of the inner pot of current microwave-steam-grill combination appliances, and the fact that the shielding component is prone to gaps with the inner pot, causing 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 sealing element abuts against the outer wall of the inner liner and is disposed around the through hole; a bracket abuts against the side of the sealing element opposite to the inner liner;

[0011] The shielding component has an annular receiving groove on the side of the sealing component facing the inner liner. The receiving groove extends circumferentially along the sealing component, and the shielding component is disposed within the receiving groove. The shielding component is in contact with the outer wall of the inner liner.

[0012] The cooking appliance provided in this application simultaneously sets up a shielding component and a sealing component around the through hole to respectively shield microwaves and seal steam. The shielding component is placed in a receiving groove on the shielding component, which limits the shielding component. The sealing component presses the shielding component to ensure that it is in contact with the inner pot, thereby maintaining a good microwave shielding effect.

[0013] As an optional implementation, the shape of the shielding member matches the shape of the receiving groove so that the groove wall restricts the movement of the shielding member radially along the through hole.

[0014] This configuration ensures the stability of the shielding component's installation position and prevents displacement of the shielding component when the bracket abuts against it.

[0015] As an optional implementation, the receiving groove is annular, and the groove width is equal at all positions along the extending direction of the receiving groove; the width of the shielding member is equal to the width of the receiving groove.

[0016] This configuration provides excellent microwave shielding and steam sealing around the circumference of the through-hole.

[0017] As an optional implementation, along the axial direction of the through hole, the depth of the receiving groove is greater than or equal to the thickness of the shielding member, and when the shielding member contacts the outer wall of the inner liner, the sealing member is compressed by the bracket.

[0018] This configuration ensures that the seal has a certain amount of compression to maintain a good steam seal effect.

[0019] As an optional implementation, the bottom of the receiving groove is provided with a clearance hole; along the axial direction of the through hole, the clearance hole penetrates the seal; a portion of the structure of the bracket passes through the clearance hole from the side of the seal away from the receiving groove and contacts the shield inside the receiving groove.

[0020] With this configuration, the structure of the bracket passing through the clearance hole can both work with the shielding component to achieve microwave shielding and also position the sealing component.

[0021] As an optional implementation, the sealing element has an abutment groove on the side opposite to the inner liner; a portion of the bracket structure is inserted into the abutment groove and abuts against the bottom of the abutment groove to press the sealing element and the shielding element together; the clearance hole connects the receiving groove and the abutment groove.

[0022] This design allows the seals to be pre-installed on the bracket during assembly, improving assembly convenience.

[0023] As an optional implementation, the bracket includes an annular body, the abutment groove is annular, and the groove wall of the abutment groove is disposed on the inner and outer sides of the bracket.

[0024] This design ensures that there will be no steam leakage around the circumference of the support.

[0025] As an optional implementation, the annular body includes a first abutting part and a plurality of second abutting parts; the first abutting part is disposed around the outer groove wall of the abutting groove and abuts against the bottom of the abutting groove; the plurality of second abutting parts are arranged circumferentially at intervals along the inner groove wall, and there are a plurality of clearance holes, with the plurality of second abutting parts passing through the plurality of clearance holes and contacting the shielding member.

[0026] With this configuration, the bracket can both compress the shielding component and position the seal, ensuring the stability of the seal installation.

[0027] 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. The inner edge of the through hole has a flange, which is positioned inside the seal.

[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 opening of the receiving groove is annular, the outer side of the inner edge of the groove has a first sealing surface, and the outer side of the outer edge of the groove has a second sealing surface; both the first sealing surface and the second sealing surface surround the through hole and abut against the outer wall of the inner liner.

[0030] This setup creates two steam seals, improving the steam sealing effect.

[0031] The cooking appliance provided in this application includes an inner pot, a microwave module, a functional module, a seal, and a shield. 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 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. The seal abuts against the outer wall of the inner pot and surrounds the through hole. The support abuts against the side of the seal opposite to the inner pot. The shield contacts the outer wall of the inner pot. The seal has an annular receiving groove on the side facing the inner pot. The receiving groove extends circumferentially along the seal. The shield is located within the receiving groove, thereby limiting the shield. The seal presses the shield to ensure contact with the inner pot, thus maintaining a good microwave shielding effect.

[0053] 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.

[0054] To address the aforementioned technical problems, this application provides a cooking appliance that achieves steam sealing and microwave shielding by incorporating a sealing element and a shielding element, respectively. The shielding element is restrained by a receiving groove on the sealing element, and the shielding element also supports the sealing element to prevent excessive deformation. Thus, when the support presses against the sealing element and contacts the shielding element, the shielding element adheres tightly to the inner pot, providing excellent microwave shielding and preventing microwave leakage, while the sealing element maintains a good steam seal. 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 effects.

[0055] 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.

[0056] Reference Figures 1 to 4 As shown, this application 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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 of a seal in a cooking appliance provided in an embodiment of this application.

[0061] In the embodiments of this application, reference is made to Figures 1 to 7 As shown, the cooking appliance 10 includes an inner pot 100, a microwave module 200, and a functional module 300.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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 and both abut against the outer wall of the inner pot 100.

[0067] The sealing element 500 abuts against the outer wall of the inner liner 100 and is arranged around the through hole 102. The bracket 320 abuts against the side of the sealing element 500 away from the inner liner 100. The bracket 320 can press the sealing element 500, so that the sealing element 500 generates a certain amount of compression along the axial direction of the through hole 102, thereby playing a role in steam sealing.

[0068] Those skilled in the art will understand that the sealing member 500 has an annular receiving groove 501 on the side facing the inner liner 100, and the receiving groove 501 extends circumferentially along the sealing member 500. The shielding member 400 is disposed within the receiving groove 501 and contacts the outer wall of the inner liner 100. The receiving groove 501 serves to limit the shielding member 400, and correspondingly, the shielding member 400 can support the sealing member 500 and maintain the contour shape of the shielding member 400.

[0069] 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.

[0070] It should be noted that in the cooking appliance 10 provided in this application embodiment, a shielding member 400 and a sealing member 500 are simultaneously arranged around the through hole 102 to respectively shield microwaves and seal steam. The shielding member 400 is placed in the receiving groove 501 on the shielding member 400, which limits the shielding member 400. The sealing member 500 presses the shielding member 400 to ensure that it is in contact with the inner pot 100, thereby maintaining a good microwave shielding effect. The shielding member 400 is a rigid structure, and the shielding member 400 supports the sealing member 500, preventing the sealing member 500 from undergoing excessive deformation when compressed by the bracket 320, which would affect the steam sealing effect.

[0071] 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.

[0072] In some embodiments, the shape of the shield 400 matches the shape of the receiving groove 501 so that the groove wall of the receiving groove 501 restricts the radial movement of the shield 400 along the through hole 102, thereby ensuring the stability of the installation position of the shield 400 and preventing the shield from shifting when the bracket 320 abuts against the shield 400.

[0073] It is understood that the sealing element 500 is arranged around the through hole 102, the receiving groove 501 is a closed ring around the circumference of the sealing element 500, and the shielding element 400 is annular and correspondingly arranged within the receiving groove 501. The inner edge of the shielding element 400 abuts against the inner sidewall of the receiving groove 501, and the outer edge of the shielding element 400 abuts against the outer sidewall of the receiving groove 501, thereby the shielding element 400 provides support for the sealing element 500 radially.

[0074] For example, the receiving groove 501 is annular, and the groove width is equal at all positions along the extending direction of the receiving groove 501. The width of the shielding member 400 is equal to the width of the receiving groove 501, and it has good microwave shielding and steam sealing effect around the circumference of the through hole 102.

[0075] In some embodiments, along the axial direction of the through hole 102, the groove depth of the receiving groove 501 is greater than or equal to the thickness of the shield 400. When the shield 400 contacts the outer wall of the inner liner 100, the sealing member 500 is compressed by the bracket 320, thereby ensuring that the sealing member 500 has a certain amount of compression to maintain a good steam sealing effect.

[0076] Understandably, when the shielding member 400 is placed in the receiving groove 501, the side surface of the shielding member 400 facing inwards from the receiving groove 501 contacts the bottom wall of the receiving groove 501. If the sealing member 500 is not compressed and undergoes elastic deformation, the side surface of the shielding member 400 facing outwards from the receiving groove 501 is flush with or lower than the end face of the sealing member 500 at the opening of the receiving groove 501.

[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 bottom of the receiving groove 501 is provided with a clearance hole 502. The clearance hole 502 penetrates the seal 500 along the axial direction of the through hole 102. A portion of the structure of the bracket 320 passes through the clearance hole 502 from the side of the seal 500 away from the receiving groove 501 and contacts the shield 400 inside the receiving groove 501.

[0080] Understandably, the structure of the bracket 320 passing through the clearance hole 502 can both work with the shielding component 400 to achieve microwave shielding and also serve to position the sealing component 500.

[0081] In some embodiments, the seal 500 has an abutment groove 503 on the side opposite to the inner liner 100. A portion of the bracket 320 is inserted into the abutment groove 503 and abuts against the bottom of the abutment groove 503 to press the seal 500 and the shield 400 together. The clearance hole 502 connects the receiving groove 501 and the abutment groove 503.

[0082] It is understandable that when assembling the seal 500, the seal 500 can be pre-installed on the bracket 320 to improve assembly convenience.

[0083] For example, the cross-section of the seal 500 can be in the shape of an "I".

[0084] In some embodiments, the bracket 320 may include an annular body 321, and the abutment groove 503 is annular. The groove wall of the abutment groove 503 is wrapped around the inner and outer sides of the bracket 320, thereby ensuring that there is no steam leakage around the circumference of the bracket 320.

[0085] The annular body 321 may include a first abutting portion 3211 and multiple second abutting portions 3212. The first abutting portion 3211 is disposed around the outer groove wall of the abutting groove 503 and abuts against the bottom of the groove 503. The multiple second abutting portions 3212 are arranged circumferentially at intervals along the inner groove wall. There are multiple clearance holes 502, and the multiple second abutting portions 3212 are respectively inserted through the multiple clearance holes 502 and contact the shield 400. The bracket 320 can also position the sealing element 500 while pressing the shield 400, ensuring the installation stability of the sealing element 500.

[0086] For example, the first abutment portion 3211 and the second abutment portion 3212 can be two coaxially arranged annular bosses. When assembling the seal 500, the seal 500 can be sleeved on the top ends of the first abutment portion 3211 and the second abutment portion 3212. Since the first abutment portion 3211 and the second abutment portion 3212 respectively abut against the seal 500, the seal 500 is opened and fixed, so that the seal 500 maintains two reliable vapor sealing structures.

[0087] For example, the height difference between the top end of the first abutment portion 3211 and the top end of the second abutment portion 3212 is less than the thickness of the pressing portion. This ensures that when the bracket 320 contacts the shield 400, the pressing portion can form a certain amount of compression, thereby generating pressure on the shield 400 and achieving a better vapor sealing effect.

[0088] For example, the second abutment portion 3212 may be arc-shaped, and the shape and size of the clearance hole 502 may match that of the second abutment portion 3212. When the second abutment portion 3212 is inserted into the clearance hole 502, the seal 500 may be prevented from rotating axially.

[0089] For example, the second abutment portion 3212 can be circular, elliptical or other shapes, and the shape and size of the clearance hole 502 match the second abutment portion 3212. This application embodiment does not specifically limit this.

[0090] For example, the number of second abutment portions 3212 can be one, two, three, four or more, and the number of clearance holes 502 is equal to the number of second abutment portions 3212.

[0091] In some embodiments, the opening of the receiving groove 501 is annular, with a first sealing surface 504 on the outer side of the inner edge of the opening and a second sealing surface 505 on the outer side of the outer edge of the opening. Both the first sealing surface 504 and the second sealing surface 505 surround the through hole 102 and abut against the outer wall of the inner liner 100, thereby forming two steam sealing structures and improving the steam sealing effect.

[0092] 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.

[0093] Figure 8 A cross-sectional view of a functional module in a cooking appliance provided in an embodiment of this application; 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 the cooking utensil provided in the embodiments 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 embodiment of this application.

[0094] 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 located outside the inner liner 100 and is connected to the bracket 320. The fan blade 313 is located 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. The output shaft 312 has a gap with the inner edge of the through hole 102.

[0095] The inner edge of the through hole 102 has a flange, which is located inside the seal 500.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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 is blocked on the inner side of the seal 500500.

[0104] For example, the first limiting part 103 can be a flange structure circumferentially connected to the through hole 102.

[0105] In some embodiments, the cooking appliance 10 may further include a connector 140, a first fastener 141, and a second fastener 142. The first connector 140 passes sequentially through the side wall of the inner pot 100 and the bracket 320 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 bracket 320. The second fastener 142 is located on the side of the bracket 320 opposite to the inner pot 100 and is locked to the connector 140, thereby improving the installation reliability of the bracket 320.

[0106] 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 bracket 320 can be installed onto the connector 140, and the mounting plate can be fixed by screwing the second fastener 142 onto the connector 140.

[0107] 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 100, or part of the structure can be installed on the back side of the inner pot 100 and part of the structure can be installed on the top of the inner pot 100. The specific structure and installation position of the microwave structure are not limited in this embodiment.

[0108] The cooking appliance provided in this application includes an inner pot, a microwave module, a functional module, a seal, and a shield. 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 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. The seal abuts against the outer wall of the inner pot and surrounds the through hole. The support abuts against the side of the seal opposite to the inner pot. The shield contacts the outer wall of the inner pot. The seal has an annular receiving groove on the side facing the inner pot. The receiving groove extends circumferentially along the seal. The shield is located within the receiving groove, thereby limiting the shield. The seal presses the shield to ensure contact with the inner pot, thus maintaining a good microwave shielding effect.
