Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The following is for reference. Figures 1-5 A cooking apparatus 100 according to an embodiment of the present utility model is described.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The cooking device 100 according to an embodiment of the present invention includes: an inner pot 1 and a hot air hood 2. The hot air hood 2 is disposed on the inner wall of the inner pot 1, and a holding cavity is defined between the inner wall of the hot air hood 2 and the inner pot 1. A cooking cavity is defined between the outer wall of the hot air hood 2 and the inner pot 1. A carbon heater 3 is disposed in the holding cavity, and food is placed in the cooking cavity. The hot air hood 2 is provided with an air inlet area 21 and an air outlet area 22, which are respectively connected to the holding cavity and the cooking cavity, allowing air in the cooking cavity to enter the holding cavity through the air inlet area 21 and air in the holding cavity to enter the cooking cavity through the air outlet area 22, thus achieving air circulation between the holding cavity and the cooking cavity.

[0034] Specifically, a fan 5 is installed in the holding cavity and / or cooking cavity. When the fan 5 is working, it drives the air in the cooking cavity to enter the holding cavity through the air inlet area 21, and the air in the holding cavity enters the cooking zone through the air outlet area 22. The air circulates in the holding cavity and the cooking cavity.

[0035] The cooking device 100 in this embodiment of the present invention has a hot air cooking mode. In the hot air cooking mode, the carbon heater 3 works to generate heat. The air in the cooking cavity enters the holding cavity through the air inlet area 21, and the air in the holding cavity enters the cooking zone through the air outlet area 22. The air circulates in the holding cavity and the cooking cavity. When the flowing air passes through the carbon heater 3, it exchanges heat with the carbon heater 3. When the hot air flows to the food in the cooking cavity, it bakes the food, thus realizing hot air cooking.

[0036] The cooking device 100 of this embodiment further includes a microwave generator and a shielding component 4. The microwave generator is used to output microwaves into the cooking cavity. The cooking device 100 of this embodiment has a microwave cooking mode. In the microwave cooking mode, the microwave generator outputs microwaves into the cooking cavity to heat the food inside the cooking cavity.

[0037] However, in microwave cooking mode, there is a risk that microwaves in the cooking cavity may enter the container cavity. If microwaves enter the container cavity and act on the carbon heater 3, the carbon heater 3 will absorb too many microwaves, causing microwave flashing. This will cause the local temperature of the carbon heater 3 to rise too quickly, thus affecting the service life and efficiency of the carbon heater 3. Therefore, the cooking device 100 in this embodiment of the present invention also includes a shielding component 4. The shielding component 4 is configured to block microwaves from being transmitted towards the carbon heater 3, avoiding the situation where the carbon heater 3 flashes due to microwave influence, and extending the service life of the carbon heater 3.

[0038] The cooking device 100 according to the present invention not only has a hot air cooking mode, but also a microwave cooking mode. Furthermore, the microwave transmitted toward the carbon heater 3 is shielded by the shielding component 4, which prevents the microwave from affecting the carbon heater 3, avoids the carbon heater 3 from flashing, and extends the service life of the carbon heater 3.

[0039] The inner liner 1 and the hot air hood 2 are typically made of metal. Both the surface of the inner liner 1 and the surface of the hot air hood 2 are coated. This coating can be enamel, a rust-proof coating, or other coatings; this invention does not limit this. When the surface of the hot air hood 2 is in contact with the surface of the inner liner 1, it is actually the coating on the surface of the hot air hood 2 that is in contact with the coating on the surface of the inner liner 1. The metal layer of the hot air hood 2 and the metal layer of the inner liner 1 are actually spaced apart.

[0040] In other words, there are at least two coating layers between the metal layer of the hot air cover 2 and the metal layer of the inner pot 1. The metal can shield microwaves, but the coatings on the hot air cover 2 and the inner pot 1 cannot shield microwaves. Therefore, in microwave cooking mode, microwaves in the cooking cavity may pass through the coating between the hot air cover 2 and the inner pot 1 and enter the holding cavity.

[0041] To prevent microwaves from entering the container cavity through the coating between the hot air hood 2 and the inner liner 1, in some embodiments, the shielding assembly 4 includes a first shield 41. The hot air hood 2 includes a main body 23 and a fitting portion 24. An opening is provided on one side of the main body 23, and the inner wall of the inner liner 1 closes the opening on the main body 23, thus defining the container cavity between the inner liner 1 and the inner wall of the main body 23. The fitting portion 24 is disposed on the side of the main body 23 with the opening and surrounds the opening. The fitting portion 24 is fitted to the inner wall of the inner liner 1, defining the first shield 41. The width of the fitting portion 24 is H, where H ≥ 8 mm.

[0042] When microwaves pass through the coating between the hot air hood 2 and the inner liner 1, they propagate between the metal layer of the inner liner 1 and the metal layer of the bonding part 24. When microwaves propagate between the two metal layers, they are absorbed by the metal layers. The longer the propagation channel, the more microwaves are absorbed. This invention extends the propagation path of microwaves between the metal layers of the inner liner 1 and the metal layers of the bonding part 24 by increasing the width of the bonding part 24. As a result, microwaves entering between the metal layers of the inner liner 1 and the metal layers of the bonding part 24 are absorbed and cannot enter the holding cavity, thus achieving the effect of microwave shielding.

[0043] In this embodiment of the invention, by increasing the width of the bonding portion 24, the propagation path of microwaves between the metal layer of the inner liner 1 and the metal layer of the bonding portion 24 is extended, so that the microwaves entering between the metal layer of the inner liner 1 and the metal layer of the bonding portion 24 are absorbed and cannot enter the holding cavity, effectively reducing the risk of microwaves entering the holding space and reducing the risk of the carbon heater 3 being affected by microwaves.

[0044] In some specific embodiments, the width H of the fitting portion 24 is 8mm, 10mm, 12mm, 13mm, 15mm or other dimensions.

[0045] In some further embodiments, the fitting portion 24 and the main body portion 23 are constructed as an integral molded part.

[0046] Through the above technical solution, on the one hand, the cost of the hot air cover 2 is reduced, and on the other hand, the connection strength between the bonding part 24 and the main body 23 is improved. In addition, the bonding part 24 and the main body 23 are constructed as an integral molded part, that is, there is no installation gap between the bonding part 24 and the main body 23, which avoids the risk of microwaves passing between the bonding part 24 and the main body 23, and further reduces the risk of the carbon heater 3 being affected by microwaves.

[0047] In some further embodiments, one of the inner liner 1 and the fitting portion 24 is provided with a first groove, which is an annular groove surrounding the main body portion 23, and the other of the inner liner 1 and the fitting portion 24 is provided with a first protrusion, which is an annular protrusion adapted to the first groove and is embedded in the first groove.

[0048] Through the above technical solution, on the one hand, the positioning between the hot air cover 2 and the inner liner 1 is achieved by the cooperation of the first protrusion and the first groove, which improves the convenience of installing the hot air cover 2; on the other hand, the cooperation of the first protrusion and the first groove further extends the propagation path of microwaves between the metal layer of the inner liner 1 and the metal layer of the bonding part 24, so that the microwaves entering between the metal layer of the inner liner 1 and the metal layer of the bonding part 24 are absorbed and cannot enter the holding cavity, effectively reducing the risk of microwaves entering the holding space and reducing the risk of the carbon heater 3 being affected by microwaves.

[0049] In some specific embodiments, the inner liner 1 is provided with a first groove, and the fitting part 24 is provided with a first protrusion, the first protrusion being embedded in the first groove.

[0050] Reference Figure 3 and Figure 4 In some specific embodiments, the shielding component 4 includes a second shield 42, at least a portion of which is located between the hot air hood 2 and the inner liner 1.

[0051] If the hot air hood 2 is directly attached to the inner liner 1, two coating layers are provided between the metal layers of the hot air hood 2 and the inner liner 1. In this embodiment of the invention, a second shielding element 42 is provided between the hot air hood 2 and the inner liner 1. There is only one coating layer between the metal layer of the hot air hood 2 and the second shielding element 42, and there is also only one coating layer between the metal layer of the inner liner 1 and the second shielding element 42. This effectively reduces the cross-sectional area of ​​the channel through which microwaves can pass between the hot air hood 2 and the inner liner 1, thereby achieving the effect of shielding microwaves and effectively reducing the risk of microwaves entering the holding space and reducing the risk of the carbon heater 3 being affected by microwaves.

[0052] In some embodiments, the second shield 42 is formed as a closed-loop structure, the second shield 42 is located between the hot air hood 2 and the inner liner 1, and the second shield 42 is disposed around the opening of the main body 23.

[0053] The above technical solution ensures that the opening is surrounded by the second shield 42, preventing microwaves from entering the holding cavity from the periphery of the opening.

[0054] In some further embodiments, the second shielding member 42 is a metal component. In this embodiment of the invention, the second shielding member 42 has a simple structure, reducing the cost of the cooking equipment 100.

[0055] In some specific embodiments, the second shield 42 is made of copper. In this embodiment of the present invention, the material of the second shield 42 is relatively soft. When the second shield 42 is sandwiched between the fitting part 24 and the inner liner 1, the second shield 42 can act as a sealing gasket, reduce the gap between the hot air cover 2 and the inner liner 1, and further reduce the risk of microwaves entering the holding cavity.

[0056] In some embodiments, a portion of the hot air shroud 2 is located within the second shield 42, further reducing the possibility of microwaves entering the containment cavity from between the hot air shroud 2 and the second shield 42.

[0057] In some specific embodiments, the second shielding member 42 includes a first part 421, a second part 422 and a third part 423. The first part 421 is located between the hot air hood 2 and the inner liner 1. The third part 423 is located on the side of the first part 421 away from the inner liner 1. The second part 422 is located outside the hot air hood 2 and connects the first part 421 and the third part 423. A limiting groove is defined between the first part 421, the second part 422 and the third part 423. The fitting part 24 of the hot air hood 2 is located in the limiting groove.

[0058] In this embodiment, the second shield 42 has a simple structure, is easy to manufacture, and is also easy to connect with the hot air cover 2, further reducing the cost of the cooking equipment 100.

[0059] Reference Figure 5 In some embodiments, the shielding component 4 includes a third shield 43 disposed inside the holding cavity and the third shield 43 is fitted over the carbon heater 3.

[0060] In this embodiment of the present invention, the third shield 43 is fitted over the carbon heater 3, which can block microwaves on the outside of the third shield 43, preventing microwaves from contacting the carbon heater 3 and effectively reducing the risk of the carbon heater 3 being affected by microwaves.

[0061] In some further embodiments, a third shield 43 is provided to enclose the carbon heater 3, and the third shield 43 is configured to be light-transmitting.

[0062] When current is applied to the carbon heater 3, it will generate thermal radiation and visible light. The thermal radiation is used to heat the air and / or directly heat the food. The visible light allows the user to easily check the state of the food and also to determine whether the carbon heater 3 is working properly by whether there is visible light. If no visible light is emitted after the carbon heater 3 is turned on, it means that the carbon heater 3 is damaged, and the user is reminded to have it repaired.

[0063] It should be noted that the raw materials for the heating element of the carbon heater 3 may include natural graphite, artificial graphite, and / or graphene. Preferably, the carbon heater 3 includes a graphene heating element, which has good heating performance and improves the cooking effect of the cooking device 100 in the hot air cooking mode.

[0064] The third shielding element 43 is configured to shield microwaves while allowing light to pass through. The third shielding element 43 is set to enclose the carbon heater 3, so that the third shielding element 43 can shield microwaves on the side away from the carbon heater 3, avoiding the carbon heater 3 from flickering. At the same time, the heat radiation and visible light emitted by the carbon heater 3 can also be emitted through the third shielding element 43, ensuring the heating effect of the carbon heater 3.

[0065] It should also be noted that the third shielding element 43 is configured to shield microwaves. This can be a metal structure, conductive plastic, or a conductive coating; other structures are also acceptable as long as they can shield microwaves. Furthermore, the third shielding element 43 is configured to be light-transmitting. This can be achieved by providing light-transmitting holes or by using a material that allows light to pass through. This invention does not impose any limitations on these aspects.

[0066] In some specific embodiments, the third shield 43 is provided to enclose the carbon heater 3, and the third shield 43 is a metal part and is formed in a mesh shape.

[0067] In the above technical solution, the third shielding component 43 is a metal mesh structure, which is easy to process and form, reduces the processing cost of the third shielding component 43, and the metal structure has high stability, which extends the service life of the third shielding component 43.

[0068] In some further embodiments, the mesh-like third shield 43 has a plurality of mesh openings for light transmission, the maximum distance between two points of the mesh openings being R, where R satisfies: R≤6mm.

[0069] If R > 6mm, microwaves may pass through the mesh and the third shield 43, causing the third shield 43 to fail.

[0070] The above technical solution, by limiting the size of the mesh, avoids the risk of shielding failure due to excessively large meshes, thus ensuring the ability of the third shielding component 43 to shield microwaves.

[0071] In some embodiments, the maximum distance R between two points of the mesh is 6 mm. In other embodiments, the maximum distance R between two points of the mesh can also be other sizes such as 5 mm, 4.5 mm, 4 mm, etc.

[0072] In some specific embodiments, the third shielding element 43 is constructed as a metal mesh made of metal wire, and the third shielding element 43 has diamond-shaped mesh openings. The maximum distance between two points of the mesh opening is R, where R is 5mm. Of course, in other embodiments, the mesh openings can also be square, rectangular, circular, etc., and this utility model does not limit the shape of the mesh openings.

[0073] In some specific embodiments, the shielding component 4 includes the first shield 41, the second shield 42, and the third shield 43 described above. By using three different shielding components to shield microwaves, the influence of microwaves on the carbon heating element 3 is effectively avoided, further improving the reliability of the cooking equipment 100.

[0074] Reference Figure 1 and Figure 2 In some embodiments, the hot air hood 2 is provided with multiple ventilation holes, which define an air inlet area 21 and an air outlet area 22. The diameter of the ventilation holes is D, which satisfies: D≤5mm.

[0075] If D > 5 mm, microwaves may enter the container cavity through the ventilation hole, thus affecting the carbon heater 3.

[0076] The above technical solution avoids the risk of microwaves entering the storage cavity due to excessively large ventilation holes by limiting the size of the ventilation holes.

[0077] In some embodiments, the diameter D of the ventilation hole is 5 mm. In other embodiments, the diameter D of the ventilation hole can also be other sizes such as 4 mm, 3.5 mm, and 3 mm.

[0078] In some embodiments, the hot air shroud 2 is grounded.

[0079] The above technical solution enables the hot air cover 2 to form an equipotential body with the ground, effectively improving the ability of the hot air cover 2 to shield microwaves.

[0080] In some specific embodiments, the hot air hood 2 is fixed to the inner liner 1 by fasteners, so that the hot air hood 2 and the inner liner 1 are electrically connected, that is, the hot air hood 2 is grounded through the inner liner 1.

[0081] To ensure the safety of the cooking equipment 100, the inner pot 1 is grounded. In this invention, the hot air hood 2 is electrically connected to the inner pot 1, which can realize the grounding connection of the hot air hood 2. The grounding method of the hot air hood 2 is simple and reduces the cost of the cooking equipment 100.

[0082] In some specific embodiments, the fitting part 24 is provided with a plurality of mounting holes 241. The fitting part 24 is fixed to the inner liner 1 by fasteners passing through the mounting holes 241. The installation method of the hot air cover 2 in this embodiment is simple and reduces the cost of the cooking equipment 100.

[0083] Other configurations of the cooking apparatus 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0084] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
