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] Shielding components and seals,

[0011] Both the shield and the seal abut against the outer wall of the inner liner and are arranged around the through hole; the shield and the seal overlap in the orthogonal projection of the through hole in the axial direction; in the overlapping area, the seal is located on the side of the shield away from the inner liner, the bracket abuts against the side of the seal away from the shield, and the bracket presses the seal and the shield together along the axial direction of the through hole; a portion of the structure of the bracket contacts the shield.

[0012] The cooking appliance provided in this application simultaneously sets up a shield and a seal around the through hole to respectively shield microwaves and seal steam. The sealant and the shield overlap in the axial projection of the through hole, so that the support can press the seal and the shield together at the same time. The seal and the shield can be as close to the through hole as possible, so as to better prevent steam leakage while ensuring good microwave shielding effect.

[0013] As an alternative implementation, the shield is annular; along the radial direction of the through hole, the sealing portion extends to the outer and / or inner side of the shield and abuts against the outer wall of the inner liner.

[0014] This design ensures that at least part of the sealing element on the inner or outer side of the shield can contact and press against the outer surface of the inner liner, thereby achieving a better effect in preventing steam leakage.

[0015] As an optional implementation, the sealing element includes a sealing portion and a pressing portion, the sealing portion being disposed around the through hole; the pressing portion being connected to the sealing portion along the radial direction of the through hole; the pressing portion abutting against the side of the shielding element opposite to the inner liner, and the sealing portion and the shielding element being arranged radially along the through hole.

[0016] With this configuration, in addition to the part of the bracket that directly contacts the shielding component, a clamping force can be applied through the sealing part. This improves the stability of the shielding component without affecting the sealing effect of the sealing part, and prevents the shielding component from sliding and leaking microwaves.

[0017] As an optional implementation, there are two sealing parts, which are coaxially arranged around the through hole. The clamping part is connected between the two sealing parts, and the shielding member is located between the two sealing parts. The inner and outer sides of the shielding member abut against the two sealing parts respectively.

[0018] This design creates a double-layer sealing structure, improving the steam sealing effect.

[0019] As an optional implementation, the clamping part is provided with a clearance hole; along the axial direction of the through hole, the clearance hole connects both sides of the seal, and a part of the bracket structure passes through the clearance hole and contacts the shield.

[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 bracket has a first abutting portion and a second abutting portion. The first abutting portion abuts against the side of the pressing portion away from the shielding member. The second abutting portion is opposite to the clearance hole, and the top end of the second abutting portion and the top end of the first abutting portion have a height difference along the axial direction of the through hole. The second abutting portion passes through the clearance hole and contacts the shielding member.

[0022] This design allows the sealing structures on both the inner and outer sides of the seal to be compressed, ensuring a good steam seal effect.

[0023] As an optional implementation, the height difference between the top tip of the first abutment and the top tip of the second abutment is less than the thickness of the pressing part.

[0024] This design ensures that when the bracket comes into contact with the shielding component, the clamping part can form a certain amount of compression, thereby generating pressure on the shielding component and achieving a better steam sealing effect.

[0025] As an optional implementation, the first abutting part is annular and surrounds the through hole, and the second abutting part is located inside the first abutting part; there are multiple second abutting parts and multiple clearance holes, and the multiple second abutting parts are arranged at intervals along the circumference of the first abutting part, and the multiple second abutting parts correspond one-to-one with the multiple clearance holes.

[0026] This configuration, while compressing the shielding component, also positions the sealing component, ensuring the stability of the sealing component during 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.

[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 inner edge of the through hole is provided with a first limiting part, which is bent toward the outside of the cooking cavity and blocks the inside of the seal.

[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] The cooking appliance provided in this application includes an inner pot, a microwave module, a functional module, a shield, and a seal. 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. Both the shield and the seal abut against the outer wall of the inner pot and are arranged around the through hole. Along the axial direction of the through hole, the orthographic projections of the shield and the seal overlap. In the overlapping area, the seal is located on the side of the shield away from the inner pot, and the support abuts against the side of the seal away from the shield. The support presses the seal and the shield along the axial direction of the through hole. A portion of the support is in contact with the shield, so that the support can simultaneously press the seal and the shield. The seal and the shield can be as close as possible to the through hole, ensuring good microwave shielding while better preventing steam leakage.

[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 sealing element and shielding element are installed and positioned using a functional module's bracket. The sealing element and shielding element partially overlap, allowing the bracket to not only contact the shielding element but also press the shielding element firmly against the inner pot using the contact area of ​​the sealing element, thus achieving a good microwave shielding effect and preventing microwave leakage. Compared to existing technologies, the cooking appliance of this application has a simpler overall sealing structure, is easier to assemble, and provides better microwave shielding and steam sealing 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] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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; Figure 8 A cross-sectional view of a functional module in a cooking appliance provided in an embodiment of this application.

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

[0067] Both the shield 400 and the seal 500 are arranged around the through hole 102. The orthographic projections of the shield 400 and the seal 500 overlap along the axial direction of the through hole 102. When the bracket 320 presses the seal 500 axially along the through hole 102, the seal 500 can apply pressure to the shield 400.

[0068] Understandably, in the overlapping area of ​​the seal 500 and the shield 400, the seal 500 is located on the side of the shield 400 away from the inner liner 100, and the bracket 320 abuts against the side of the seal 500 away from the shield 400. The bracket 320 axially presses the seal 500 and the shield 400 along the through hole 102.

[0069] Part of the structure of the bracket 320 is in contact with the shielding component 400, so that the inner liner 100, the shielding component 400, and the bracket 320 can come into contact in sequence to achieve the microwave shielding effect.

[0070] It should be noted that in the cooking appliance 10 provided in this application embodiment, the sealant and the shield 400 overlap in the axial projection of the through hole 102, so that the support 320 can simultaneously press the seal 500 and the shield 400. The seal 500 and the shield 400 can be as close as possible to the through hole 102, which can better prevent steam leakage while ensuring good microwave shielding 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 shield 400 is annular.

[0073] Understandably, the bracket 320 is installed onto the inner liner 100, with the bracket 320 opposite to the through hole 102. If the bracket 320 were directly installed and sealed to the inner liner 100, there would be a gap. Therefore, a shield 400 and a seal 500 are provided between the bracket 320 and the inner liner 100 to form two annular protective structures.

[0074] For example, along the radial direction of the through hole 102, a portion of the sealing element 500 extends to the inner side of the shield 400 and abuts against the outer wall of the inner liner 100. That is, the projection of the sealing element 500 along the axial direction of the through hole 102 extends beyond the inner edge of the shield 400. This ensures that the structure of the sealing element 500 inside the shield 400 can contact and press against the outer surface of the inner liner 100, thereby achieving a better effect in preventing steam leakage.

[0075] For example, along the radial direction of the through hole 102, a portion of the sealing element 500 extends to the outside of the shield 400 and abuts against the outer wall of the inner liner 100. That is, the projection of the sealing element 500 along the axial direction of the through hole 102 extends beyond the outer edge of the shield 400. This ensures that the structure of the sealing element 500 on the outside of the shield 400 can contact and press against the outer surface of the inner liner 100, thereby achieving a better effect in preventing steam leakage.

[0076] For example, along the radial direction of the through hole 102, a portion of the structure of the sealing element 500 extends to both the outer and inner sides of the shield 400 and abuts against the outer wall of the inner liner 100. That is, the projection of the sealing element 500 along the axial direction of the through hole 102 extends beyond both the inner and outer edges of the shield 400. This ensures that the structures of the sealing element 500 on both the inner and outer sides of the shield 400 can contact and press against the outer surface of the inner liner 100, thereby achieving a better effect in preventing steam leakage.

[0077] In some embodiments, the seal 500 may include a sealing portion 510 and a clamping portion 520. The sealing portion 510 is disposed around the through hole 102. The radial projection of the clamping portion 520 along the through hole 102 overlaps with the shield 400.

[0078] Along the radial direction of the through hole 102, the clamping part 520 is connected to the sealing part 510. The clamping part 520 abuts against the side of the shield 400 away from the inner liner 100, and the sealing part 510 and the shield 400 are arranged radially along the through hole 102.

[0079] Understandably, in addition to the part of the bracket 320 that directly contacts the shield 400, a clamping force can be applied through the sealing part 510. This improves the stability of the shield 400 without affecting the sealing effect of the sealing part 510, and prevents the shield 400 from sliding and leaking microwaves.

[0080] For example, there are two sealing parts 510, which are coaxially arranged around the through hole 102. A pressing part 520 is connected between the two sealing parts 510, and a shielding member 400 is located between the two sealing parts 510. The inner and outer sides of the shielding member 400 abut against the two sealing parts 510 respectively, thereby forming a double-layer sealing structure and improving the steam sealing effect.

[0081] 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.

[0082] 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.

[0083] In some embodiments, the clamping part 520 is provided with a clearance hole 521. Along the axial direction of the through hole 102, the clearance hole 521 connects both sides of the sealing member 500, and a portion of the structure of the bracket 320 passes through the clearance hole 521 to contact the shielding member 400. The structure of the bracket 320 passing through the clearance hole 521 can both cooperate with the shielding member 400 to achieve a microwave shielding effect and provide a positioning function for the sealing member 500.

[0084] The bracket 320 has a first abutting portion 3211 and a second abutting portion 3212. The first abutting portion 3211 abuts against the side of the pressing portion 520 away from the shield 400. The second abutting portion 3212 is opposite to the clearance hole 521, and the top end of the second abutting portion 3212 and the top end of the first abutting portion 3211 have a height difference along the axial direction of the through hole 102. The second abutting portion 3212 passes through the clearance hole 521 and contacts the shield 400, so that the sealing structures on both the inner and outer sides of the sealing member 500 can be compressed to ensure a good steam sealing effect.

[0085] 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.

[0086] In some embodiments, the top end of the second abutment portion 3212 has multiple protruding structures and multiple clearance holes 521. The multiple clearance holes 521 are circumferentially spaced around the through hole 102. The multiple protruding structures are arranged one-to-one with the multiple clearance holes 521 and respectively pass through the corresponding clearance holes 521 to contact the shield 400. The protruding structures can also position the sealing member 500 while pressing the shield 400, ensuring the installation stability of the sealing member 500.

[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 520. This ensures that when the bracket 320 contacts the shield 400, the pressing portion 520 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 protrusion may be arc-shaped, and the shape and size of the clearance hole 521 are matched with the protrusion. The protrusion is inserted into the clearance hole 521 to prevent the seal 500 from rotating axially.

[0089] For example, the protrusion structure can be circular, elliptical or other shapes, and the shape and size of the clearance hole 521 are matched with the protrusion structure. This application embodiment does not specifically limit this.

[0090] For example, the number of protrusions can be one, two, three, four or more, and the number of clearance holes 521 is equal to the number of protrusions.

[0091] In other embodiments, the first abutment portion 3211 is annular and surrounds the through hole 102, and the second abutment portion 3212 is located inside the first abutment portion 3211. There can be multiple second abutment portions 3212 and multiple clearance holes 521. The multiple second abutment portions 3212 are arranged at intervals along the circumference of the first abutment portion 3211, and the multiple second abutment portions 3212 correspond one-to-one with the multiple clearance holes 521.

[0092] Understandably, each of the second abutment portions 3212 forms a protruding structure, which can position the seal 500 while pressing the shield 400, ensuring the installation stability of the seal 500.

[0093] It should be noted that the sealing part 510 and the pressing part 520 can be integrally molded parts. During assembly, the sealing element 500 is coaxially sleeved on the bracket 320 as a whole, and the sealing element 500 is fixed by the friction between the bracket 320 and the sealing element 500. Then, the shielding element 400 can be placed on the sealing element 500. Finally, the functional module 300 is installed as a whole on the inner liner 100. The bracket 320 can press the sealing element 500 and the shielding element 400 along the axial direction of the through hole 102. In this way, the assembly convenience of the sealing element 500 and the shielding element 400 can be improved, and the product manufacturing cost can be reduced.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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. The first limiting part 103 is blocked on the inner side of the sealing member 500, thereby radially limiting the installation position of the sealing member 500 and avoiding deviation of the position of the sealing member or excessive deformation of the sealing member 500 that would affect the steam sealing effect.

[0105] For example, the first limiting part 103 can be a flange structure circumferentially connected to the through hole 102.

[0106] For example, the inner liner 100 has a recessed groove on its back side, and a through hole 102 can be formed in the middle of the recessed groove. When assembling the functional module 300, the sealing member 500 and the shielding member 400 are located in the recessed groove. The recessed groove causes the inner rear sidewall of the cooking cavity 101 to protrude forward. In this way, when assembling the functional module 300, it can provide a pre-position for the abutment and engagement of the shielding member 400 and the sealing member 500 with the inner liner 100.

[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 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.

[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 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.

[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 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.

[0110] The cooking appliance provided in this application includes an inner pot, a microwave module, a functional module, a shield, and a seal. 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. Both the shield and the seal abut against the outer wall of the inner pot and are arranged around the through hole. Along the axial direction of the through hole, the projected portions of the shield and the seal overlap. In the overlapping area, the seal is located on the side of the shield away from the inner pot, and the support abuts against the side of the seal away from the shield, pressing the seal and the shield together along the axial direction of the through hole. A portion of the support contacts the shield, thereby allowing the support to simultaneously press the seal and the shield together. The seal and the shield can be as close as possible to the through hole, ensuring good microwave shielding while better preventing steam leakage.
