Description

Technical Field

[0001] The present invention relates to the technical field of cooking, and particularly to a cooking device. Background Art

[0002] Existing cooking devices (such as built-in steam ovens) are developing rapidly in the direction of food recognition, and various camera technologies are emerging in an endless stream. To achieve this function, the camera is usually embedded in the glass of the door body to maintain the overall beauty and practicality of the device. However, during use, the temperature of the camera and the door body glass is relatively high, posing certain potential safety hazards. High temperature over a long period may have a negative impact on the performance and lifespan of the camera, and may even cause the camera to malfunction or be damaged. The high-temperature door body glass may not only scald users, but also affect the user's operation experience. Summary of the Invention

[0003] In view of this, the present invention provides a cooking device to solve the problems that in the existing cooking device during use, the temperature of the camera and the door body glass is relatively high, posing certain potential safety hazards, high temperature over a long period may have a negative impact on the performance and lifespan of the camera, and may even cause the camera to malfunction or be damaged, and the high-temperature door body glass may not only scald users, but also affect the user's operation experience.

[0004] The first aspect of the present invention provides a cooking device, including an inner container, a door body structure, a camera module, and a heat dissipation device. The inner container has an opening, the door body structure is movably arranged at the opening, the door body structure has a first air duct, an air inlet and an air outlet communicated with the first air duct. The camera module is installed in the first air duct. The heat dissipation device includes a heat dissipation fan installed in the inner container. The air suction port of the heat dissipation fan is communicated with the air outlet. External air flows into the first air duct from the air inlet under the action of the heat dissipation fan to dissipate heat from the camera module in the first air duct, and the air in the first air duct flows to the air suction port of the heat dissipation fan through the air outlet.

[0005] Beneficial Effects: In the cooking device of the present application, during the cooking process, the heat dissipation fan can suck air, so that external air flows into the first air duct through the air inlet under the action of negative pressure, flows through the camera module and flows out towards the air outlet, and finally flows to the air suction port of the heat dissipation fan, thereby realizing convective heat dissipation of the door body structure and the camera module, avoiding the camera module from malfunctioning or being damaged due to excessive temperature, avoiding the door body structure from scalding users due to excessive temperature, improving the user's use safety, and at the same time reducing the user's waiting time.

[0006] In some embodiments, the door body structure includes a first layer of glass and a second layer of glass. The first layer of glass is arranged facing the inside of the inner container, the second layer of glass is arranged facing the outside of the inner container, and the first air duct is located between the first layer of glass and the second layer of glass.

[0007] Beneficial effects: The door body structure adopts a double-layer glass form, which is convenient for users to observe the inside of the cooking device through the door body structure. The double-layer glass can improve the heat insulation performance of the door body structure, reduce heat loss during cooking, and also facilitate the formation of the first air duct between the first layer of glass and the second layer of glass, which is beneficial to the convective heat dissipation of the door body structure.

[0008] In some embodiments, a heat insulation coating is provided on the side of the first layer of glass facing the inner container.

[0009] Beneficial effects: A heat insulation coating is provided on the side of the first layer of glass facing the inner container. The heat insulation coating can play a heat insulation role, reduce the heat dissipation of the inner container during cooking, and also reduce the heat transfer to the camera module, thereby reducing the temperature rise of the camera module.

[0010] In some embodiments, the cooking device further includes a fixed support assembly. The fixed support assembly is arranged in the first air duct, and the camera module is arranged on the fixed support assembly.

[0011] Beneficial effects: The setting of the fixed support assembly can facilitate the installation of the camera module and ensure the installation stability of the camera module.

[0012] In some embodiments, the fixed support assembly includes a first bracket and a second bracket. The first bracket is arranged in the first air duct and is close to the first layer of glass. The second bracket is arranged in the first air duct and is close to the second layer of glass. There is a first gap between the first bracket and the second bracket. The camera module is arranged on the first bracket and / or the second bracket, and the camera module communicates with the first gap.

[0013] Beneficial effects: When the air flows to the fixed support assembly, it flows along the first gap between the first bracket and the second bracket. Since the first gap has a throttling effect, it can pressurize and speed up the air flowing through, that is, the air speeds up when flowing out of the first gap, thereby enhancing the convective heat dissipation effect of the air on the door body structure and the camera module, which is beneficial to temperature reduction.

[0014] In some embodiments, the first bracket has a heat insulation function, and there is a second gap between the first bracket and the first layer of glass. The camera module communicates with the second gap.

[0015] Beneficial effects: The first bracket can isolate the heat of the first layer of glass, thereby reducing heat dissipation during cooking, ensuring the cooking effect, and at the same time reducing the heat transfer to the camera module and lowering the temperature of the camera module. The second gap provided between the first bracket and the first layer of glass can further convectively dissipate heat from the camera module and lower the temperature at the camera of the camera module.

[0016] In some embodiments, the second bracket has a heat conduction function, and the second bracket is disposed in close contact with the second layer of glass.

[0017] Beneficial effects: The second bracket has a heat conduction function, which is conducive to the heat transfer of the second layer of glass to the second bracket and dissipates heat through the air convection of the first air duct, thereby ensuring the heat dissipation and temperature reduction of the second layer of glass.

[0018] In some embodiments, the fixed support assembly further includes a fixed seat, and both ends of the first bracket and both ends of the second bracket are fixed to the door body structure through the fixed seat.

[0019] Beneficial effects: The setting of the fixed seat facilitates the installation of the air duct assembly on the door body structure and ensures the position stability of the fixed support assembly.

[0020] In some embodiments, the width A of the first gap satisfies A≥9 mm.

[0021] Beneficial effects: By setting the width of the first gap to be greater than or equal to 9 millimeters, it can ensure that while the air speed is increased when the air flows through the first gap, the air resistance will not be too large due to the too small size of the first gap, affecting the air circulation.

[0022] In some embodiments, the width B of the second gap satisfies B≥5 mm.

[0023] Beneficial effects: Since the smaller the width B of the second gap, the closer the camera module is to the inner tank and the higher the temperature rise, by setting the width of the second gap to be greater than or equal to 5 millimeters, it can ensure that the temperature rise of the camera module meets the standard and avoid damage to the camera module caused by excessive temperature rise.

[0024] In some embodiments, the camera module includes a camera, a flash, and a circuit board. The camera is disposed on the first bracket, the camera communicates with both the first gap and the second gap, the flash is disposed on the first bracket, the flash communicates with both the first gap and the second gap, the circuit board is electrically connected to both the camera and the flash, the circuit board is disposed on the second bracket, and the circuit board communicates with the first gap.

[0025] Beneficial effects: The first gap and the second gap can reduce the resistance of air flowing through the fixed support assembly, enabling air to flow through quickly and increase the speed. When air flows through the first gap and the second gap, convective heat dissipation of the camera, the flashlight, and the circuit board is achieved, thereby reducing the temperature of the camera module. Since the camera and the flashlight are closer to the first layer of glass, the air flowing out through the first gap and the second gap simultaneously conducts convective heat dissipation to enhance the heat dissipation effect. The circuit board is far from the first layer of glass, so only the air flowing out through the first gap is used for heat dissipation.

[0026] In some embodiments, a first mounting groove is provided on one side of the first bracket facing the second bracket. The first mounting groove communicates with the first gap, and both the camera and the flashlight are disposed in the first mounting groove.

[0027] Beneficial effects: The provision of the first mounting groove defines an installable space, facilitating the installation of the camera and the flashlight, and preventing the installation of the camera and the flashlight from blocking the air flowing through the first gap. When air flows through the first gap, it flows into the first mounting groove to achieve convective heat dissipation of the camera and the flashlight mounted thereon.

[0028] In some embodiments, a second mounting groove is provided on one side of the second bracket facing the first bracket. The second mounting groove communicates with the first gap, and the circuit board is disposed in the second mounting groove.

[0029] Beneficial effects: The provision of the second mounting groove defines an installable space, facilitating the installation of the circuit board, and preventing the installation of the circuit board from blocking the air flowing through the first gap. When air flows through the first gap, it flows into the second mounting groove to achieve convective heat dissipation of the circuit board mounted thereon.

[0030] In some embodiments, the first mounting groove and the second mounting groove are opposite to each other, and the sum C of the depth of the first mounting groove, the depth of the second mounting groove, and the width of the first gap satisfies C≥18 mm.

[0031] Beneficial effects: By setting the sum C of the depth of the first mounting groove, the depth of the second mounting groove, and the width of the first gap to be greater than or equal to 18 millimeters, it can ensure that more air can flow through the gap between the first mounting groove and the second mounting groove, thereby achieving overall convective heat dissipation of the camera module.

[0032] It can be understood that in this embodiment, the sum C of the depth of the first mounting groove, the depth of the second mounting groove, and the width of the first gap > the size of the first gap, that is, the air passing resistance between the first mounting groove and the second mounting groove is less than the air passing resistance of the first gap. When air flows, it will preferentially pass through the gap between the first mounting groove and the second mounting groove, thereby enhancing the heat dissipation effect of the camera module.

[0033] In some embodiments, a diversion inclined plane is provided on one side of the first bracket facing the first-layer glass. The top of the diversion inclined plane inclines towards the first-layer glass, and the bottom of the diversion inclined plane inclines away from the first-layer glass. Moreover, the bottom of the diversion inclined plane communicates with the first gap. The camera and / or the flash are vertically installed on the diversion inclined plane, and there is a fitting gap between the camera and the first-layer glass.

[0034] Beneficial effects: The provision of the diversion inclined plane facilitates the inclined installation of the camera to ensure that the camera and / or the flash incline towards the inside of the cooking device, achieving the shooting and illumination of the internal food. Meanwhile, when air flows through the first gap, part of the air flows along the diversion inclined plane, thereby realizing convective heat dissipation for the camera and / or the flash on the diversion inclined plane, taking away the heat of the camera and / or the flash, and reducing the temperature of the camera and / or the flash.

[0035] In some embodiments, the distance L1 between the top of the end of the camera facing the first-layer glass and the first-layer glass satisfies L1≥4mm.

[0036] Beneficial effects: By setting the distance L1 between the top of the end of the camera facing the first-layer glass and the first-layer glass to be greater than or equal to 4 millimeters, it can ensure the shooting of the internal food by the camera and avoid the lens of the camera malfunctioning or being damaged due to the too small distance L1 between the top of the lens of the camera and the first-layer glass.

[0037] In some embodiments, the distance L2 between the bottom of the end of the camera facing the first-layer glass and the first-layer glass satisfies L2≥8mm.

[0038] Beneficial effects: By setting the distance L2 between the bottom of the end of the camera facing the first-layer glass and the first-layer glass to be greater than or equal to 8 millimeters, it can ensure that the camera is at a suitable inclination angle to achieve clear shooting of the internal food and avoid the insufficient downward inclination angle of the camera due to the too small distance L2 between the bottom of the lens of the camera and the first-layer glass, making it difficult to achieve shooting.

[0039] In some embodiments, along the flowing direction of the gas, the cross-sectional dimension of the air inlet gradually increases.

[0040] Beneficial effects: By setting the cross-sectional dimension of the air inlet to gradually increase along the flowing direction of the gas, the air presents a profile shape when flowing along the air inlet, which can expand the blowing range of the air flowing into the first air duct, thereby reducing the blowing dead angle of the first air duct and enhancing the heat dissipation intensity of the door body structure.

[0041] In some embodiments, the door body structure further includes a top bracket, a bottom bracket, and two side brackets. The top bracket is located at the top of the first layer of glass and the second layer of glass, and the bottom bracket is located at the bottom of the first layer of glass and the second layer of glass. One of the side brackets is disposed on one side of the first layer of glass and the second layer of glass, and the other side bracket is disposed on the other side of the first layer of glass and the second layer of glass. The top bracket, the bottom bracket, the two side brackets, the first layer of glass, and the second layer of glass cooperate to form the first air duct, and the air inlet is disposed on the bottom bracket.

[0042] Beneficial effects: The top bracket, the bottom bracket, and the two side brackets jointly form the door body structure. When air flows through the first air duct from the air inlet of the bottom bracket, convective heat dissipation of the top bracket, the bottom bracket, the two side brackets, the first layer of glass, and the second layer of glass is achieved, taking away the heat generated by cooking, thereby reducing the temperature of the door body.

[0043] In some embodiments, the door body structure further includes an insect-proof board disposed in the first air duct and opposite to the top bracket. The insect-proof board is provided with air passing holes, and an air outlet is formed between the insect-proof board and the top bracket.

[0044] Beneficial effects: The space of the first air duct is small, and it is difficult to clean when insects and other foreign objects enter. The insect-proof board can prevent insects and external foreign objects from entering the first air duct and causing blockage, ensuring the normal flow of the first air duct.

[0045] In some embodiments, the heat dissipation device further includes a second air duct, and the air suction port of the heat dissipation fan is communicated with the air outlet of the first air duct through the second air duct.

[0046] Beneficial effects: The second air duct can make the air flowing out of the first air duct better flow to the air suction port of the heat dissipation fan, forming an air circulation flow.

[0047] In some embodiments, the cooking device includes an embedded steam oven. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0071] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "first", "second", "third", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0072] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0073] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0074] The embodiments of the present invention will be described below in conjunction with Figures 1 to 15 .

[0075] As Figure 1 and Figure 2 shown, according to an embodiment of the present invention, on the one hand, a cooking device is disclosed, which includes an inner container 1, a door structure 2, a camera module 3, and a heat dissipation device 4. Among them, the inner container 1 has an opening, the door structure 2 is movably arranged at the opening, the door structure 2 has a first air duct 211, an air inlet 241 communicated with the first air duct 211, and an air outlet. The camera module 3 is installed in the first air duct 211. The heat dissipation device 4 includes a heat dissipation fan 41 installed in the inner container 1. The air suction port and the air outlet of the heat dissipation fan 41 are communicated. External air flows into the first air duct 211 from the air inlet 241 under the action of the heat dissipation fan 41 to dissipate heat from the camera module 3 in the first air duct 211, and the air in the first air duct 211 flows through the air outlet to the air suction port of the heat dissipation fan 41.

[0076] In the cooking device of the present application, during the cooking process, the heat dissipation fan 41 can suck air, so that external air flows into the first air duct 211 through the air inlet 241 under the action of negative pressure, flows through the camera module 3 and flows out towards the air outlet, and finally flows to the air suction port of the heat dissipation fan 41, thereby realizing convective heat dissipation of the door structure 2 and the camera module 3, avoiding faults or damages caused by too high temperature of the camera module 3, avoiding scalding users due to too high temperature of the door structure 2, improving the user's use safety, and at the same time reducing the user's waiting time.

[0077] The present application does not limit the shape of the inner container 1, which can be cylindrical, ellipsoidal or geometric.

[0078] The opening can be circular, elliptical or geometric, for example, the opening can be rectangular.

[0079] The door structure 2 is rotatably connected to the opening, and the opening is opened or closed by the rotation of the door structure 2 relative to the inner container 1. However, it is not limited thereto. For example, in other embodiments, the door structure 2 can also be detachably connected to the opening.

[0080] For the convenience of opening, a handle 27 is provided on the door structure 2, and the door structure 2 can be driven to open or close the opening of the inner container 1 through the handle 27, and the operation is convenient and labor-saving.

[0081] As Figures 1 - 3 shown, in some embodiments, the door structure 2 includes a first layer of glass 21 and a second layer of glass 22. The first layer of glass 21 is arranged on the inner side facing the inner container 1, the second layer of glass 22 is arranged on the outer side facing the inner container 1, and the first air duct 211 is located between the first layer of glass 21 and the second layer of glass 22.

[0082] The door body structure 2 adopts a double - layer glass form, which is convenient for users to observe the inside of the cooking device through the door body structure 2. The double - layer glass can improve the heat insulation performance of the door body structure 2, reduce the heat loss during cooking, and also facilitate the formation of a first air duct 211 between the first - layer glass 21 and the second - layer glass 22, which is beneficial to the convective heat dissipation of the door body structure 2.

[0083] In some embodiments, a heat - insulating coating is provided on the side of the first - layer glass 21 facing the inner container 1.

[0084] When a heat - insulating coating is provided on the side of the first - layer glass 21 facing the inner container 1, the heat - insulating coating can play a heat - insulating role, reduce the heat dissipation from the inner container during cooking, and also reduce the heat transfer to the camera module 3, thereby reducing the temperature rise of the camera module 3.

[0085] Specifically, the first - layer glass 21 is closer to the cooking cavity, and Low - E glass with a low emissivity can be selected, which can greatly weaken the radiative heat transfer and reduce the heat loss during cooking. Of course, in other embodiments, the first - layer glass 21 can also use ordinary glass, not limited to this embodiment.

[0086] As Figure 3 shown, in some embodiments, the cooking device further includes a fixed support assembly 5. The fixed support assembly 5 is arranged in the first air duct 211, and the camera module 3 is arranged on the fixed support assembly 5.

[0087] The setting of the fixed support assembly 5 can facilitate the installation of the camera module 3 and ensure the installation stability of the camera module 3.

[0088] As Figure 3 and Figure 4 shown, in some embodiments, the fixed support assembly 5 includes a first bracket 51 and a second bracket 52. Among them, the first bracket 51 is arranged in the first air duct 211 and is close to the first - layer glass 21. The second bracket 52 is arranged in the first air duct 211 and is close to the second - layer glass 22. There is a first gap 511 between the first bracket 51 and the second bracket 52. The camera module 3 is arranged on the first bracket 51 and / or the second bracket 52, and the camera module 3 communicates with the first gap 511.

[0089] When the air flows to the fixed support assembly 5, it flows along the first gap 511 between the first bracket 51 and the second bracket 52. Since the first gap 511 has a throttling effect, it can pressurize and speed up the air flowing through, that is, the air speeds up when flowing out of the first gap 511, thereby enhancing the convective heat dissipation effect of the air on the door body structure 2 and the camera module 3, which is beneficial to temperature reduction.

[0090] It can be understood that the first bracket 51 and the second bracket 52 themselves have a thickness. The first bracket 51 and the second bracket 52 are arranged inside the first air duct 211. Therefore, the size of the first gap 511 is smaller than the width of the first air duct 211. When the air flows to the first gap 511, the channel changes from large to small, thereby achieving speed increase, enhancing the gas flow speed, and enhancing the convective heat dissipation effect.

[0091] As Figure 6 shown, in some embodiments, the first bracket 51 has a heat insulation function. A second gap 512 is provided between the first bracket 51 and the first layer of glass 21. The imaging module 3 communicates with the second gap 512.

[0092] The first bracket 51 can isolate the heat of the first layer of glass 21, thereby reducing the heat dissipation during cooking, ensuring the cooking effect, and at the same time reducing the heat transfer to the imaging module 3 and lowering the temperature of the imaging module 3. The second gap 512 provided between the first bracket 51 and the first layer of glass 21 can further conduct convective heat dissipation to the imaging module 3 and lower the temperature at the camera 31 of the imaging module 3.

[0093] Specifically, the first bracket 51 can be made of plastic and formed by an injection molding process. However, it is not limited to this. In other embodiments, the first bracket 51 can also be made of other materials that can play a heat insulation role.

[0094] In some embodiments, the second bracket 52 has a heat conduction function, and the second bracket 52 is attached to the second layer of glass 22.

[0095] The second bracket 52 has a heat conduction function, which is conducive to the heat transfer of the second layer of glass 22 to the second bracket 52 and dissipates heat through the air convection of the first air duct 211, thereby ensuring the heat dissipation and cooling of the second layer of glass 22.

[0096] Specifically, the second bracket 52 can be made of aluminum alloy to achieve high heat conduction. However, it is not limited to this. In other embodiments, the second bracket 52 can also be made of other materials that can play a heat conduction role.

[0097] As Figures 3 - 5 shown, in some embodiments, the fixed support assembly 5 further includes a fixed seat 53. Both ends of the first bracket 51 and both ends of the second bracket 52 are fixed to the door body structure 2 through the fixed seat 53.

[0098] The setting of the fixed seat 53 facilitates the installation of the air duct component on the door body structure 2 and ensures the position stability of the fixed support assembly 5.

[0099] Specifically, two fixing seats 53 may be provided. The first ends of the first bracket 51 and the second bracket 52 are embedded and installed in one of the fixing seats 53, and the second ends of the first bracket 51 and the second bracket 52 are embedded and installed in the other fixing seat 53, thereby realizing the installation and positioning of the first bracket 51 and the second bracket 52.

[0100] As Figure 6 shown, in some embodiments, the width A of the first gap 511 satisfies A≥9 mm.

[0101] By setting the width of the first gap 511 to be greater than or equal to 9 millimeters, it can be ensured that while the air speed is increased when the air flows through the first gap 511, the air resistance will not be too large due to the too small size of the first gap 511, affecting the air flow.

[0102] Exemplarily, the width A of the first gap 511 can be 9 mm, 10 mm, 11 mm, 12 mm, etc., which is specifically set according to needs and is not limited in this embodiment.

[0103] As Figure 6 shown, in some embodiments, the width B of the second gap 512 satisfies B≥5 mm.

[0104] Since the smaller the width B of the second gap 512, the closer the imaging module 3 is to the inner tank 1 and the higher the temperature rise, by setting the width B of the second gap 512 to be greater than or equal to 5 millimeters, it can be ensured that the temperature rise of the imaging module 3 meets the standard and the imaging module 3 is prevented from being damaged due to excessive temperature rise.

[0105] Exemplarily, the width B of the second gap 512 can be 5 mm, 6 mm, 7 mm, 8 mm, etc., which is specifically set according to needs and is not limited in this embodiment.

[0106] As Figure 3 、 Figure 4 and Figure 5 shown, in some embodiments, the imaging module 3 includes a camera 31, a flash 32, and a circuit board 33. Among them, the camera 31 is disposed on the first bracket 51, the camera 31 communicates with both the first gap 511 and the second gap 512, the flash 32 is disposed on the first bracket 51, the flash 32 communicates with both the first gap 511 and the second gap 512, the circuit board 33 is electrically connected to both the camera 31 and the flash 32, the circuit board 33 is disposed on the second bracket 52, and the circuit board 33 communicates with the first gap 511.

[0107] The first gap 511 and the second gap 512 can reduce the resistance of air flowing through the fixed support assembly 5, enabling the air to flow through quickly to increase the speed. When the air flows through the first gap 511 and the second gap 512, convective heat dissipation of the camera 31, the diffused light lamp, and the circuit board 33 is achieved, thereby reducing the temperature of the camera module 3. Since the camera 31 and the diffused light lamp are closer to the first-layer glass 21, the air flowing out through the first gap 511 and the second gap 512 dissipates heat by convection simultaneously to enhance the heat dissipation effect. The circuit board 33 is far from the first-layer glass 21, so only the air flowing out through the first gap 511 is used for heat dissipation.

[0108] As Figure 5 , Figure 6 shown, in some embodiments, a first mounting groove 513 is provided on the side of the first bracket 51 facing the second bracket 52. The first mounting groove 513 communicates with the first gap 511, and both the camera 31 and the flash lamp 32 are disposed in the first mounting groove 513.

[0109] The provision of the first mounting groove 513 defines an installable space, facilitating the installation of the camera 31 and the flash lamp 32, and preventing the installation of the camera 31 and the flash lamp 32 from blocking the air flow through the first gap 511. When the air flows through the first gap 511, it flows into the first mounting groove 513 to achieve convective heat dissipation of the camera 31 and the flash lamp 32 mounted thereon.

[0110] As Figure 5 , Figure 6 shown, in some embodiments, a second mounting groove 521 is provided on the side of the second bracket 52 facing the first bracket 51. The second mounting groove 521 communicates with the first gap 511, and the circuit board 33 is disposed in the second mounting groove 521.

[0111] The provision of the second mounting groove 521 defines an installable space, facilitating the installation of the circuit board 33, and preventing the installation of the circuit board 33 from blocking the air flow through the first gap 511. When the air flows through the first gap 511, it flows into the second mounting groove 521 to achieve convective heat dissipation of the circuit board 33 mounted thereon.

[0112] As Figure 6 shown, in some embodiments, the first mounting groove 513 and the second mounting groove 521 are opposite to each other, and the sum C of the depth of the first mounting groove 513, the depth of the second mounting groove 521, and the width of the first gap 511 satisfies C≥18 mm.

[0113] By setting the sum C of the depth of the first mounting groove 513, the depth of the second mounting groove 521, and the width of the first gap 511 to be greater than or equal to 18 millimeters, it can be ensured that more air can flow through the gap between the first mounting groove 513 and the second mounting groove 521, thereby achieving overall convective heat dissipation of the camera module 3.

[0114] It can be understood that in this embodiment, the sum C of the depth of the first installation groove 513, the depth of the second installation groove 521, and the width of the first gap 511 is greater than the size of the first gap 511, that is, the air passage resistance between the first installation groove 513 and the second installation groove 521 is less than the air passage resistance of the first gap 511. When air flows, it will preferentially pass through the gap between the first installation groove 513 and the second installation groove 521, thereby improving the heat dissipation effect of the camera module 3.

[0115] Exemplarily, the sum C of the depth of the first installation groove 513, the depth of the second installation groove 521, and the width of the first gap 511 can be 18mm, 19mm, 20mm, 21mm, etc., which is specifically set according to needs and is not limited in this embodiment.

[0116] Furthermore, the circuit board 33 is placed opposite to the camera 31 and on the side close to the second-layer glass 22. On the one hand, part of the radiation of the circuit board 33 can be blocked by the camera 31, and on the other hand, the circuit board 33 can be made farther away from the first-layer glass 21, reducing the temperature rise of the circuit board 33.

[0117] As Figure 4 shown, in some embodiments, a diversion inclined surface 514 communicating with the second gap 512 is provided on the side of the first bracket 51 facing the first-layer glass 21. The top of the diversion inclined surface 514 is inclined towards the first-layer glass 21, the bottom of the diversion inclined surface 514 is inclined away from the first-layer glass 21, and the bottom of the diversion inclined surface communicates with the first gap. The camera 31 and / or the flash are vertically installed on the diversion inclined surface 514, and there is a fitting gap between the camera 31 and the first-layer glass 21.

[0118] The setting of the diversion inclined surface 514 facilitates the inclined installation of the camera 31 and / or the flash, so as to ensure that the camera 31 and / or the flash 32 are inclined towards the inside of the cooking device to realize the shooting and illumination of the internal food. At the same time, when air flows through the first gap 511, part of the air flows along the diversion inclined surface 514 through the first gap 511, thereby realizing convective heat dissipation for the camera 31 and / or the flash 32 on the diversion inclined surface 514, taking away the heat of the camera 31 and / or the flash 32, and reducing the temperature of the camera 31 and / or the flash 32.

[0119] It should be noted here that when the camera 31 and / or the flash 32 are vertically installed on the diversion inclined surface 514, the axis of the camera 31 and / or the center line of the flash 32 are perpendicular to the diversion inclined surface 514 to ensure that the camera 31 and / or the flash 32 are in a downward viewing angle towards the inside of the cooking device to realize the shooting and illumination of the internal food.

[0120] In this embodiment, both the camera 31 and the flash 32 are disposed on the diversion inclined surface 514. There are multiple flashes 32 which are distributed on both sides of the camera 31, so as to illuminate the interior of the cooking device with a flash when the camera 31 takes a picture, ensuring clear imaging during shooting. The lens of the camera 31 and the irradiation end of the flash 32 communicate with the second gap 512, and the back of the camera 31 and the back of the flash 32 communicate with the first gap 511. An opening is provided at the bottom of the diversion inclined surface 514, and the opening penetrates through the bottom of the first bracket 51. The bottom of the diversion inclined surface 514 communicates with the first gap 511 through the opening, that is to say, the first gap 511 communicates with the second gap 512 through the opening. When air passes through the first gap 511, convective heat dissipation is performed on the back of the camera 31 and the back of the flash 32. Part of the air in the first gap 511 flows through the opening to the diversion inclined surface 514, performing convective heat dissipation on the lens of the camera 31 and the irradiation end of the flash 32, and finally converging and flowing to the second gap 512, thereby achieving sufficient convective heat dissipation for the flash 32 and the camera 31.

[0121] As Figure 7 shown, in some embodiments, the distance L1 between the top of the end of the camera 31 facing the first layer of glass 21 and the first layer of glass 21 satisfies L1≥4 mm.

[0122] By setting the distance L1 between the top of the end of the camera 31 (where the lens is installed) facing the first layer of glass 21 and the first layer of glass 21 to be greater than or equal to 4 millimeters, it can ensure the shooting of the internal food by the camera 31, and avoid the lens of the camera 31 from malfunctioning or being damaged due to the too small distance L1 between the top of the lens and the first layer of glass 21.

[0123] Exemplarily, the distance L1 between the top of the end of the camera 31 (where the lens is installed) facing the first layer of glass 21 and the first layer of glass 21 can be 4 mm, 5 mm, 6 mm, 7 mm, etc., which is specifically set according to needs and is not limited in this embodiment.

[0124] As Figure 7 shown, in some embodiments, the distance L2 between the bottom of the end of the camera 31 facing the first layer of glass 21 and the first layer of glass 21 satisfies L2≥8 mm.

[0125] By setting the distance L2 between the bottom of the end of the camera 31 (where the lens is installed) facing the first layer of glass 21 and the first layer of glass 21 to be greater than or equal to 8 millimeters, it can ensure that the camera 31 is at a proper inclination angle to achieve clear shooting of the internal food, and avoid the camera 31 from having insufficient downward inclination angle and being difficult to achieve shooting due to the too small distance L2 between the bottom of the lens and the first layer of glass 21.

[0126] Exemplarily, the distance L2 between the bottom of the camera 31 facing one end (where the lens is installed) of the first-layer glass 21 and the first-layer glass 21 can be 8 mm, 9 mm, 10 mm, 11 mm, etc., which is specifically set according to needs and is not limited in this embodiment.

[0127] By reasonably setting the distances between the top and bottom of the end of the camera 31 where the lens is installed and the first-layer glass 21, food recognition inside the cooking device can be achieved through shooting by the lens, including food type recognition and food doneness recognition. The user can remotely view the cooking degree of the food inside the cooking device through the camera 31 and remotely control the cooking device.

[0128] Through the above settings, air can flow through the lens and the back of the camera 31, which can effectively reduce the temperature of the lens of the camera 31, and the temperature of the lens of the camera 31 can be reduced from 62 °C to 51 °C.

[0129] As Figure 8 shown, in some embodiments, along the gas flow direction, the cross-sectional dimension of the air inlet 241 gradually increases.

[0130] By setting the cross-sectional dimension of the air inlet 241 to gradually increase along the gas flow direction, the air presents a tapered shape when flowing along the air inlet 241, which can expand the blowing range of the air flowing into the first air duct 211, thereby reducing the blowing dead angle of the first air duct 211 and enhancing the heat dissipation intensity of the door body structure 2.

[0131] Specifically, the air inlet 241 can be set to a trumpet shape, an inverted cone shape, etc., and this embodiment does not make specific limitations.

[0132] As Figure 2 、 Figure 3 shown, in some embodiments, the door body structure 2 further includes a top bracket 23, a bottom bracket 24, and two side brackets 25. Among them, the top bracket 23 is located at the top of the first-layer glass 21 and the second-layer glass 22, the bottom bracket 24 is located at the bottom of the first-layer glass 21 and the second-layer glass 22, one of the side brackets 25 is disposed on one side of the first-layer glass 21 and the second-layer glass 22, and the other side bracket 25 is disposed on the other side of the first-layer glass 21 and the second-layer glass 22. The top bracket 23, the bottom bracket 24, the two side brackets 25, the first-layer glass 21, and the second-layer glass 22 cooperate to form the first air duct 211, and the air inlet 241 is disposed on the bottom bracket 24.

[0133] The top bracket 23, the bottom bracket 24, and the two side brackets 25 together form the door body structure 2. When air flows through the first air duct 211 from the air inlet 241 of the bottom bracket 24, convective heat dissipation of the top bracket 23, the bottom bracket 24, the two side brackets 25, the first layer of glass 21, and the second layer of glass 22 is achieved, taking away the heat generated by cooking, thereby reducing the temperature of the door body.

[0134] Specifically, as Figure 8 shown, to increase the air flow rate, a plurality of air inlets 241 are arranged in an array on the bottom bracket 24.

[0135] Of course, in other embodiments, the air inlet 241 can also be arranged at positions such as the side bracket 25 or the top bracket 23, not limited to this embodiment.

[0136] As Figure 2 、 Figure 3 shown, in some embodiments, the door body structure 2 further includes an insect screen 26 disposed in the first air duct 211 and opposite to the top bracket 23. The insect screen 26 is provided with air passing holes 261, and an air outlet is formed between the insect screen 26 and the top bracket 23.

[0137] The space of the first air duct 211 is small, and it is difficult to clean when insects and other foreign objects enter. The insect screen 26 can prevent insects and external foreign objects from entering the first air duct 211 and causing blockage, ensuring the normal operation of the first air duct 211.

[0138] As Figure 9 shown, a plurality of air passing holes 261 are arranged in an array on the insect screen 26, facilitating the passage of air and increasing the air flow rate.

[0139] As Figure 2 shown, in some embodiments, the heat dissipation device 4 further includes a second air duct 421, and the suction port of the heat dissipation fan 41 is communicated with the air outlet of the first air duct 211 through the second air duct 421.

[0140] The second air duct 421 can make the air flowing out of the first air duct 211 better flow to the suction port of the heat dissipation fan 41, forming an air circulation flow.

[0141] Specifically, as Figure 2 、 Figure 3 shown, the heat dissipation device 4 further includes a first air duct cover 42, and the second air duct 421 is formed inside the first air duct cover 42.

[0142] As Figure 2 、 Figure 3 shown, in this embodiment, the heat dissipation device 4 is further provided with a second air duct cover 43. The second air duct cover 43 has a third air duct 431 inside, and the third air duct 431 is communicated with the blowing port of the heat dissipation fan 41, so that air is blown from the heat dissipation fan 41 and blown out through the third air duct 431.

[0143] Specifically, the cooling fan 41 can be arranged at the top of the inner container 1. The first air duct cover plate 42 is arranged at the top of the inner container 1 and connected to the cooling fan 41. The second air duct cover plate 43 is arranged on the top of the first air duct cover plate 42 and connected to the cooling fan 41. However, it is not limited thereto. In other embodiments, the positions of the cooling fan 41, the first air duct cover plate 42 and the second air duct cover plate 43 can be set as required.

[0144] In this application, the cooling fan 41 drives air to be inhaled from the air inlet 241 into the first air duct 211, flow through components such as the fixed support assembly 5 and the imaging module 3, be inhaled into the cooling fan 41 through the insect-proof plate 26, the air outlet and the second air duct 421, and finally be discharged from the cooking device through the third air duct 431. The advantage of this setting is that when sucking air, the air flowing through the door structure 2 is more evenly distributed. If exhausting air into the first air duct 211 inside the door structure 2, a large amount of air flow will be blocked by the upper insect-proof plate 26, and the air flow entering the door structure 2 will be disordered and difficult to be discharged from the air inlet 241 of the bottom bracket 24.

[0145] As Figures 10 to 15 shown, in order to more clearly show the design advantages of this application, in the simulation calculation results, Figure 10 This is the flow field distribution diagram of the air of the cooking device of this application in the first air duct 211, Figure 13 and this is the flow field distribution diagram of the air of the cooking device in the prior art in the first air duct 211. It can be seen that the air speed of this application becomes larger when flowing through the fixed support assembly 5 and the imaging module 3, while the air speed in the prior art is blocked and decreased when flowing through the camera 31. Further, according to Figure 11 , Figure 12 , Figure 13 and Figure 14 analysis, after heat dissipation by air convection, the temperatures of the imaging module 3 and the door structure 2 of this application are lower than those of the imaging module 3 and the door structure 2 in the prior art. That is to say, the air convection heat dissipation effect of this application is better.

[0146] By analyzing the guide rails 12 and 13, it is proved that when there are guide rails, it is beneficial to strengthen heat dissipation.

[0147] In some embodiments, the cooking device includes an embedded steam oven.

[0148] Of course, the cooking device is not limited to the embedded steam oven. In other embodiments, the cooking device can also include an air fryer, etc.

[0149] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
