[0066] The micro-steaming and baking all-in-one machine is a commonly used cooking appliance at present, which integrates steaming function, baking function and microwave function. The micro-steaming and baking all-in-one machine needs to be provided with a heating fan module and a microwave module at the same time. The heating fan assembly is separately mounted and detached from the rear side of the inner container of the all-in-one machine. A through hole needs to be formed on the inner container. The through hole is used for the motor shaft of the heating fan assembly to pass through, so as to connect the internal fan blade to blow hot air forward. Since the all-in-one machine needs to perform steaming function and microwave cooking function, the through hole on the inner container needs to be sealed. However, the sealing effect of the inner container of the current micro-steaming and baking all-in-one machine is poor, and steam and microwave leakage is prone to occur. In addition, the complex assembly and sealing structure make it difficult to disassemble and clean the heating fan assembly, which not only has high cost, but also is prone to produce odor.

[0067] In view of the above technical problems, the embodiment of the present application provides a cooking appliance. The steam sealing and microwave shielding are respectively realized by setting a sealing structure and a shield. The sealing structure and the shield are installed and positioned by the bracket of the functional module, so that the shield is tightly attached to the box to achieve good microwave shielding effect. Different sealing parts of the sealing structure respectively achieve multi-layer steam sealing effect on the inner side and the outer side of the shield to prevent steam leakage. Compared with the prior art, the overall sealing structure of the cooking appliance of the present application is simple, convenient to assemble, and has better microwave shielding and steam sealing effect.

[0068] Figure 1 A structural schematic diagram of the cooking appliance provided by the embodiment of the present application is shown in the figure; Figure 2 A structural schematic diagram of the back side of the cooking appliance provided by the embodiment of the present application is shown in the figure; Figure 3 A sectional view of the cooking appliance provided by the embodiment of the present application is shown in the figure; Figure 4 A partial view of the A position in the figure. Figure 3 A partial view of the A position in the figure.

[0069] Referring to Figures 1 to 4 As shown in the figure, the embodiment of the present application provides a cooking appliance 10, which comprises a box body 100 and a shell. The box body 100 is contained in the shell, and the box body 100 has a cooking cavity 101.

[0070] In the embodiment of the present application, the type of the cooking appliance 10 is not limited. For example, the cooking appliance 10 can be an independent table type or cabinet type cooking device, or an electric appliance integrated with a gas stove or other electric appliances. In the present embodiment, the cooking appliance 10 is mainly taken as a micro-steaming and baking all-in-one machine as an example for description.

[0071] The micro-steaming and baking all-in-one machine is integrated with a microwave oven, a steaming oven and an oven, and can release the kitchen space because one machine can replace multiple kitchen appliances with independent functions. The principle of the steaming and baking function is to use the heating system of the electric appliance to heat water into steam, and use the steam to steam, bake and cook food, etc. The hot air generated by the heating assembly can be used to heat the food. The principle of the microwave function is to use microwaves to make water molecules in food vibrate at high speed, generate heat through molecular friction, and thus heat the food.

[0072] It should be noted that the box 100 in this embodiment is the inner container of the cooking appliance 10, and the cooking cavity 101 is formed in the inner container. The inner container is one of the core components of the steaming and baking all-in-one machine, and is used for cooking food. The material of the inner container is not limited. For example, the material of the inner container can be stainless steel, which can withstand high-temperature water and detergents, and has antibacterial properties and is easy to clean. Alternatively, the material of the inner container can be ceramic, which has the advantages of smoothness, slow degradation, corrosion resistance, and can increase the cleaning effect. This embodiment does not limit this.

[0073] In the embodiments of the present application, as shown in Figures 1 to 4 The cooking appliance 10 includes a box 100, a microwave module 200 and a function module 300.

[0074] The microwave module 200 is arranged in the box 100, and the microwave module 200 is used to generate microwaves to realize the function of microwave heating of food. The function module 300 is arranged in the box 100, and the function module 300 can be a module for realizing the steaming and baking function, for example, the function module 300 can be a fan assembly for blowing air into the cooking cavity 101 to realize hot air heating of food in cooperation with the heating module.

[0075] In some embodiments, the function module 300 can include a function piece 310 and a bracket 320, the bracket 320 is arranged outside the cooking cavity 101 and connected with the box 100, and the function piece 310 is connected with the bracket 320. The cavity wall of the cooking cavity 101 has a through hole 102, and part of the structure of the function piece 310 passes through the through hole 102 and inserts into the cooking cavity 101.

[0076] It can be understood that the bracket 320 plays a role of mounting and fixing the function piece 310, and the through hole 102 avoids the function piece 310. The function piece 310 can be a fan assembly, the fan blades of the fan assembly are located inside the inner container, the motor of the fan assembly is located outside the inner container, and the output shaft of the motor is connected with the fan blades through the through hole 102, so as to drive the fan blades to rotate and blow hot air to the food in the inner container.

[0077] It can be understood by those skilled in the art that, since the output shaft of the motor needs to generate rotation when the functional part 310 implements the function of the fan assembly, a gap needs to be provided between the output shaft of the motor and the through hole 102 to avoid interference. During cooking, microwaves and steam can both pass through the through hole 102 to the outside of the inner container, and therefore a sealing structure needs to be designed.

[0078] In some embodiments, the cooking appliance 10 provided by the embodiments of the present application comprises a shielding part 400 and a sealing structure 500. The shielding part 400 is arranged between the bracket 320 and the outer wall of the cooking cavity 101 and surrounds the through hole 102. The shielding part 400 is used to shield microwaves to prevent microwave leakage. The sealing structure 500 is arranged between the bracket 320 and the outer wall of the cooking cavity 101, and the sealing structure 500 is used to prevent steam leakage.

[0079] It can be understood that the sealing structure 500 comprises a first sealing part 510 and a second sealing part 520. The first sealing part 510 is arranged on the inner side of the shielding part 400 and surrounds the through hole 102, and the second sealing part 520 is arranged on the outer side of the shielding part 400. The sealing structure 500 is arranged between the bracket 320 and the outer wall of the cooking cavity 101, and the first sealing part 510 and the second sealing part 520 are elastically deformed. The first sealing part 510 and the second sealing part 520 can respectively form a steam sealing structure to prevent steam leakage.

[0080] It should be noted that, in the cooking appliance 10 provided by the embodiments of the present application, the shielding part 400 and the sealing structure 500 are arranged around the through hole 102 to respectively shield microwaves and seal steam. The shielding part 400 is arranged between the bracket 320 and the box body 100, and the sealing structure 500 forms a double-layer sealing structure on the inner side and the outer side of the shielding part 400 by using two different sealing parts. In this way, a good microwave shielding effect is ensured, and the effect of preventing steam leakage is better.

[0081] In addition, the sealing structure 500 and the shielding part 400 are both arranged on the outside of the inner container and are installed together with the bracket 320 of the functional module 300 to the box body 100. The overall sealing structure is more simple, the assembly process is less, and the assembly is convenient, so that the production manufacturing cost of the product can be reduced. Moreover, the sealing structure 500 and the shielding part 400 arranged on the outside of the inner container can avoid being in a high-humidity and high-temperature environment and an environment with oil stains in the inner container, so that the sealing structure 500 and the shielding part 400 are prevented from being corroded, and the service life is improved.

[0082] Figure 5 An exploded view of the functional module, the shielding part, and the sealing structure in the cooking appliance provided by the embodiments of the present application; Figure 6 A sectional view of the back side of the inner container in the cooking appliance provided by the embodiments of the present application;Figure 7 A cross-sectional view of the sealing structure in the cooking utensil provided by the embodiment of the present application; Figure 8 A cross-sectional view of the functional module in the cooking utensil provided by the embodiment of the present application.

[0083] Please refer to Figures 1 to 8 In a possible implementation, the first sealing part 510 and the second sealing part 520 are both annular, and the first sealing part 510 and the second sealing part 520 are concentrically arranged. The shielding part 400 is annular, and the spacing between the first sealing part 510 and the second sealing part 520 matches the width of the shielding part 400.

[0084] It can be understood that the shielding part 400, the first sealing part 510 and the second sealing part 520 all surround the through hole 102 once, and the circumferential circle of the through hole 102 can have good microwave shielding and steam sealing effects. The shielding part 400 is between the first sealing part 510 and the second sealing part 520, and the first sealing part 510 and the second sealing part 520 can limit the shielding part 400.

[0085] For example, the first sealing part 510, the shielding part 400 and the second sealing part 520 can be coaxially arranged, taking the through hole 102 as the center, and the first sealing part 510, the shielding part 400 and the second sealing part 520 are arranged in sequence from inside to outside.

[0086] For example, the inner diameter of the first sealing part 510 can be equal to or slightly larger than the diameter of the through hole 102.

[0087] For example, the shielding part 400 can be a copper mesh. The bracket 320 and the box body 100 can both be metal materials, one side of the shielding part 400 is in contact with the box body 100, and the other side is in contact with the bracket 320, thereby forming an effective microwave shielding structure.

[0088] For example, the sealing structure 500 can be an elastic material such as rubber or silica gel, and the sealing structure 500 has certain high-temperature resistance and corrosion resistance. When the bracket 320 abuts against the sealing structure 500, the sealing structure 500 can be compressed to a certain extent to improve the steam sealing effect.

[0089] It should be noted that the first sealing part 510 and the second sealing part 520 can be two independently arranged sealing parts, or two sealing structures on one sealing part. The embodiment of the present application does not make specific limitation on this.

[0090] In some embodiments, the sealing structure 500 can include a sealing body 530. The sealing body 530 is abutted on a side of the shielding member 400 away from the outer wall of the cooking cavity 101, and the sealing body 530 at least partially covers the shielding member 400. The sealing body 530 is protrudingly arranged towards a side of the box body 100, and forms the first sealing part 510 and the second sealing part 520.

[0091] It can be understood that the sealing body 530 is connected with the first sealing part 510 and the second sealing part 520 to form an integral structure. When the bracket 320 compresses the sealing structure 500, the sealing body 530 can be compressed to apply pressure to the shielding member 400, so that the sealing structure 500 can limit the shielding member 400 while playing a steam sealing role, simplifying the entire sealing structure and reducing product manufacturing and assembly costs.

[0092] For example, the first sealing part 510 and the second sealing part 520 are protruding rib structures extending on the same side of the sealing body 530.

[0093] It should be noted that the installation and fixation of the shielding member 400 and the sealing structure 500 are realized by cooperation of the two and compression of the bracket 320, without the need for other installation and fixation components.

[0094] The specific structure of the bracket 320 and the specific cooperation mode with the shielding member 400 and the sealing structure 500 will be described in detail below.

[0095] In some embodiments, the bracket 320 can include an annular body 321 abutted with the sealing body 530. The sealing body 530 can be provided with an avoiding hole 531 penetrating the sealing body 530 along the axial direction of the through hole 102, and part of the structure of the annular body 321 passes through the avoiding hole 531 to contact the shielding member 400. The annular body 321 of the bracket 320 can compress the shielding member 400 to ensure that the shielding member 400 abuts against the outer wall of the box body 100, ensuring a stable and good microwave shielding effect.

[0096] It can be understood that the annular body 321 is abutted on a side of the sealing structure 500 away from the box body 100, and the functional member 310 is installed on a side of the bracket 320 away from the box body 100. The structure of the functional member 310 can pass through the annular body 321 and be inserted into the through hole 102. When the bracket 320 is fixed to the outer side of the box body 100, the annular body 321 applies pressure to the sealing structure 500, which can correspondingly compress the shielding member 400.

[0097] In some embodiments, the annular body 321 can include a first abutting portion 3211 and a second abutting portion 3212. The first abutting portion 3211 is arranged close to the inner side of the shield 400 and compresses the sealing body 530 to make the outer side wall of the first sealing portion 510 abut the first abutting portion 3211 in the radial direction of the through hole 102, forming a secondary seal.

[0098] The second abutting portion 3212 is arranged close to the outer side of the shield 400 and compresses the sealing body 530 to make the inner side wall of the second sealing portion 520 abut the second abutting portion 3212 in the radial direction of the through hole 102, forming a secondary seal.

[0099] It can be understood that the annular body 321 of the bracket 320 can form two abutting structures for compressing the sealing structure 500, so that the inner and outer sides of the sealing structure 500 can be compressed to ensure good steam sealing effect.

[0100] For example, the first abutting portion 3211 and the second abutting portion 3212 can be two coaxially arranged annular bosses. When assembling the sealing structure 500, the sealing structure 500 can be sleeved on the top end of the first abutting portion 3211 and the second abutting portion 3212, and because the first abutting portion 3211 and the second abutting portion 3212 abut the first sealing portion 510 and the second sealing portion 520 respectively, the sealing structure 500 is supported and fixed, so that the sealing structure 500 maintains two reliable steam sealing structures.

[0101] In some embodiments, the top end of the first abutting portion 3211 has a plurality of protruding structures 3213, and the avoiding holes 531 are a plurality of avoiding holes 531 arranged at intervals around the circumference of the through hole 102. The plurality of protruding structures 3213 are arranged one by one corresponding to the plurality of avoiding holes 531, and respectively pass through the corresponding avoiding holes 531 to contact the shield 400. The protruding structure 3213 can play a positioning role on the sealing structure 500 while compressing the shield 400, ensuring the installation stability of the sealing structure 500.

[0102] It can be understood that along the axial direction of the through hole 102, the top end position of the protruding structure 3213 is higher than the top end position of the second abutting portion 3212, and there is a height difference between the two. When the protruding structure 3213 passes through the avoiding hole 531 to contact the shield 400, the second abutting portion 3212 can compress the sealing structure 500.

[0103] For example, the height difference between the protruding structure 3213 and the second abutting portion 3212 can be less than or equal to the thickness of the sealing body 530 of the sealing structure 500, so as to ensure that the top end of the second abutting portion 3212 maintains contact or compression state with the sealing body 530.

[0104] Exemplarily, the protruding structure 3213 can be in a circular arc shape, the shape and size of the avoiding hole 531 are matched with the protruding structure 3213, the protruding structure 3213 is inserted into the avoiding hole 531, and the axial rotation of the sealing structure 500 can be avoided.

[0105] Exemplarily, the protruding structure 3213 can be circular, elliptical or in other shapes, the shape and size of the avoiding hole 531 are matched with the protruding structure 3213, and the embodiments of the present application do not make specific limitations in this regard.

[0106] Exemplarily, the number of the protruding structure 3213 can be one, two, three, four or more, and the number of the avoiding hole 531 is equal to the number of the protruding structure 3213.

[0107] In some embodiments, the inner side of the first abutting portion 3211 is provided with a stepped portion 3214, and the end face of the first sealing portion 510 away from the cooking cavity 101 is at least partially in abutment with the stepped portion 3214. While the first abutting portion 3211 is pressed against the shielding member 400, the end of the first sealing portion 510 is pressed by the stepped portion 3214, so that the first sealing portion 510 can have a certain compression amount, thereby ensuring good steam sealing effect.

[0108] It can be understood that the stepped portion 3214 and the protruding structure 3213 have a height difference, and the height difference between the two can be less than or equal to the difference in thickness dimension of the first sealing portion 510 and the shielding member 400 along the axial direction of the through hole 102, so that when the protruding structure 3213 contacts the shielding member 400, the stepped portion 3214 remains in contact with and presses the end face of the first sealing portion 510 away from the box body 100.

[0109] Exemplarily, the first sealing portion 510, the second sealing portion 520 and the sealing body 530 are integrally formed. During assembly, the sealing structure 500 is coaxially sleeved on the annular body 321 as a whole, and the sealing structure 500 is fixed by the friction force between the annular body 321 and the sealing structure 500, after which the shielding member 400 can be placed on the sealing structure 500, and finally the functional module 300 is integrally installed on the box body 100, and the bracket 320 can press the sealing structure 500 and the shielding member 400 along the axial direction of the through hole 102. In this way, the assembly convenience of the sealing structure 500 and the shielding member 400 can be improved, and the product production cost can be reduced.

[0110] In some embodiments, in the radial direction of the through hole 102, the thickness of the first sealing portion 510 is less than the thickness of the second sealing portion 520. The first sealing portion 510 is prevented from being excessively deformed into the through hole 102 to form a gap and affect the sealing effect after being compressed by the flange of the through hole 102 and the shielding member 400.

[0111] In some embodiments, the thickness of the second sealing portion 520 is greater than the thickness of the first sealing portion 510 along the radial direction of the through hole 102. The first sealing portion 510 on the inner side can be as close as possible to the inner edge of the through hole 102, and the second sealing portion 520 on the outer side can have a larger sealing width after being compressed, thereby having better steam sealing performance.

[0112] It should be noted that the shielding member 400 can avoid microwave leakage between the bracket 320 and the box body 100, and the sealing structure 500 can avoid steam leakage between the bracket 320 and the box body 100. When the bracket 320 is fixed to the box body 100, the sealing structure 500 and the shielding member 400 are compressed.

[0113] The structure and mounting mode of the functional module 300 will be described in detail below by taking the fan assembly as an example.

[0115] Please refer to Figures 1 to 12 In a possible implementation, the functional member 310 can include a motor 311 and a fan blade 313. The motor 311 is arranged outside the cooking cavity 101, the motor 311 is connected to the bracket 320, the fan blade 313 is arranged inside the cooking cavity 101, and an output shaft 312 of the motor 311 is connected to the fan blade 313 through the through hole 102. The sealing structure 500 and the shielding member 400 both surround the output shaft 312.

[0116] It can be understood that the bracket 320 not only plays a role of mounting and fixing the motor 311, but also plays a role of fixing the sealing structure 500 and the shielding member 400. The bracket 320 of the motor 311 is used to fix the shielding member 400 and the sealing structure 500, which simplifies the assembly structure and improves the reliability of the sealing and shielding structure.

[0117] In some embodiments, the cooking appliance 10 can further include a fan cover plate 110, the fan cover plate 110 is arranged on the side of the fan blade 313 facing the inside of the cooking cavity 101, the fan cover plate 110 is connected to the box body 100 through a threaded fastener 120, the position where the fan cover plate 110 is connected to the threaded fastener 120 is provided with a boss 130 facing the inside of the cooking cavity 101, and the boss 130 abuts against the inner wall of the cooking cavity 101, so that the fan cover plate 110 has a gap with the inner wall of the cooking cavity 101.

[0118] It can be understood that the fan cover plate 110 can protect the fan blades 313 and shield the through hole 102 behind the fan blades 313. The fan cover plate 110 can be removed by disassembling the threaded fasteners 120, so as to facilitate cleaning of the fan blades 313 and the side wall of the cooking cavity 101.

[0119] For example, the size of the gap is greater than or equal to 3 mm, including but not limited to 3 mm, 3.1 mm, 4 mm, 5 mm, etc., and the embodiments of the present application do not make specific limitations. Controlling the gap between the fan cover plate 110 and the inner wall of the box body 100 within a reasonable range can avoid the phenomenon of sparking between the fan cover plate 110 and the inner container.

[0120] For example, the four bosses 130 can be arranged at the four corner positions of the rear side wall in the cooking cavity 101. The shape of the fan cover plate 110 can match the shape of the rear side wall of the cooking cavity 101, and the four corners of the fan cover plate 110 are connected with the four bosses 130. A plurality of ventilation holes can be arranged on the fan cover plate 110, so that the airflow formed by the fan blades 313 can pass through the fan cover plate 110 and flow to the front side of the cooking cavity 101.

[0121] In some embodiments, the cooking utensil 10 can further include a shielding sleeve 314 and a shaft sealing ring 315.

The shaft sealing ring 315 is sleeved on the output shaft 312, and the inner wall of the shaft sealing ring 315 abuts against the outer wall of the output shaft 312, and the outer wall of the shaft sealing ring 315 abuts against the bracket 320, so as to avoid microwave and steam leakage between the output shaft 312 of the motor 311 and the bracket 320.

[0122] It can be understood that the sealing ring can be made of rubber, silicone or the like. The output shaft 312 and the shaft sealing ring 315 are dynamically sealed. The shielding sleeve 314 can be a copper sleeve. The shielding sleeve 314 can be located on the rear side of the sealing ring along the axial direction of the output shaft 312.

[0123] In some embodiments, the inner edge of the through hole 102 is provided with a first limiting portion 103, and the first limiting portion 103 is arranged to be bent towards the outside of the cooking cavity 101. The first limiting portion 103 is arranged on the inner side of the first sealing portion 510.

[0124] The cooking utensil 10 can further include a mounting plate 150 connected to the outer side wall of the cooking cavity 101, the mounting plate 150 having an opening in which the sealing structure 500 is located, and a circumferential edge of the opening having a second limiting portion 151 bent towards the cabinet 100, the second limiting portion 151 being located outside the second sealing portion 520, so that the installation position of the sealing structure 500 can be radially limited to avoid position deviation or excessive deformation of the sealing structure 500 affecting the steam sealing effect.

[0125] For example, the first limiting portion 103 can be a flange structure circumferential to the through hole 102, and the second limiting portion 151 can be a flange structure circumferential to the inner edge of the opening of the mounting plate 150.

[0126] For example, the back side of the cabinet 100 is provided with a sunken groove, and the through hole 102 can be arranged at the middle position of the sunken groove, and the sealing structure 500 and the shielding member 400 are located in the sunken groove when the functional module 300 is assembled. The sunken groove makes the inner back side wall of the cooking cavity 101 protrude forward. In this way, when the functional module 300 is assembled, the abutting cooperation of the shielding member 400 and the sealing structure 500 with the cabinet 100 can be pre-positioned.

[0127] In some embodiments, the cooking utensil 10 can further include a connecting member 140, a first fastener 141 and a second fastener 142.

[0128] It can be understood that the connecting member 140 can be a bolt, and the first fastener 141 and the second fastener 142 can both be in the form of a nut. The first fastener 141 can be screwed with the connecting member 140. When assembled, the connecting member 140 can be first fixed to the cabinet 100 by the first fastener 141, then the mounting plate 150 is mounted on the connecting member 140, and the mounting plate 150 is fixed by being screwed with the connecting member 140 by the second fastener 142.

[0129] It should be noted that a heating pipe can be arranged around the fan blade 313 inside the cooking cavity 101 to generate heat to make the fan blade 313 rotate to generate hot air. The microwave module 200 can be arranged at the top of the cabinet 100, or part of the structure can be arranged at the back side of the cabinet 100, and part of the structure can be arranged at the top of the cabinet 100. The specific structure and installation position of the microwave structure are not limited in the embodiments of the present application.
