Description
Technical Field
[0001] This utility model relates to the field of cooking technology, and more specifically to cooking apparatus. Background Technology
[0002] Existing cooking appliances (such as built-in steam ovens) are rapidly evolving towards food recognition, with various camera technologies emerging. To achieve this functionality, the camera is typically embedded in the glass of the door to maintain the overall aesthetics and practicality of the device. However, this design results in high temperatures for both the camera and the door glass during use, posing certain safety hazards. Prolonged exposure to high temperatures may negatively impact the camera's performance and lifespan, potentially leading to malfunction or damage. Furthermore, the hot door glass could not only burn users but also negatively affect their user experience. Utility Model Content
[0003] In view of this, the present invention provides a cooking device to solve the problem that the camera and door glass of the existing cooking device have high temperatures during use, which pose certain safety hazards. Prolonged high temperature may negatively affect the performance and lifespan of the camera, and may even cause camera malfunction or damage. The high temperature of the door glass may not only burn the user, but also affect the user's operating experience.
[0004] The first aspect of this utility model provides a cooking device, including an inner pot, a door structure, a camera module, and a heat dissipation device. The inner pot has an opening, and the door structure is movably disposed in the opening. The door structure has a first air duct, an air inlet and an air outlet communicating 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 pot. The air intake of the heat dissipation fan is connected to the air outlet. External air flows into the first air duct from the air inlet under the action of the heat dissipation fan to convectively dissipate heat from the camera module in the first air duct. The air in the first air duct flows to the air intake of the heat dissipation fan through the air outlet.
[0005] Beneficial effects: The cooking device of this application can draw in air through a cooling fan during the cooking process, allowing outside air to flow into the first air duct through the air inlet under negative pressure, and then flow through the camera module to the air outlet, and finally to the air inlet of the cooling fan. This achieves convective heat dissipation for the door structure and the camera module, preventing the camera module from overheating and causing malfunction or damage, and preventing the door structure from overheating and burning the user, thus improving user safety and reducing user waiting time.
[0006] In some embodiments, the door structure includes a first glass layer and a second glass layer, the first glass layer being disposed facing inwards towards the inner liner, the second glass layer being disposed facing outwards towards the inner liner, and the first air duct being located between the first glass layer and the second glass layer.
[0007] Beneficial effects: The door structure adopts a double-layer glass design, which makes it convenient for users to observe the inside of the cooking device through the door structure. The double-layer glass can improve the heat insulation performance of the door structure, reduce heat loss during cooking, and also facilitate the formation of a first air duct between the first and second layers of glass, which is conducive to the convection and heat dissipation of the door structure.
[0008] In some embodiments, the side of the first glass layer facing the inner liner is provided with a heat-insulating coating.
[0009] Beneficial effects: A heat-insulating coating is provided on the side of the first glass facing the inner pot. The heat-insulating coating can play a heat-insulating role, reduce heat loss from the inner pot during cooking, and also reduce heat transfer to the camera module, thereby reducing the temperature rise of the camera module.
[0010] In some embodiments, the cooking apparatus further includes a fixed support assembly disposed in the first air duct, and the camera module is disposed in the fixed support assembly.
[0011] Beneficial effects: The fixed support components facilitate the installation of the camera module and ensure its stability.
[0012] In some embodiments, the fixed support assembly includes a first bracket and a second bracket. The first bracket is disposed in the first air duct and is located close to the first layer of glass. The second bracket is disposed in the first air duct and is located close to the second layer of glass. A first gap exists between the first bracket and the second bracket. The camera module is disposed on the first bracket and / or the second bracket, and the camera module communicates with the first gap.
[0013] Beneficial effects: When air flows toward 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 accelerate the air flowing through it. That is, the air is accelerated when it flows out of the first gap, thereby enhancing the convective heat dissipation effect of the air on the door structure and the camera module, which is beneficial for cooling.
[0014] In some embodiments, the first bracket has a heat insulation function, a second gap is provided between the first bracket and the first layer of glass, and the camera module is connected to the second gap.
[0015] Beneficial effects: The first bracket can insulate the heat of the first layer of glass, thereby reducing heat loss during cooking and ensuring cooking results. At the same time, it reduces the transfer of heat to the camera module and lowers the temperature of the camera module. The second gap set between the first bracket and the first layer of glass can further facilitate convective heat dissipation for the camera module and reduce the temperature at the camera of the camera module.
[0016] In some embodiments, the second bracket has a thermal conductive function, and the second bracket and the second layer of glass are bonded together.
[0017] Beneficial effects: The second support has a thermal conductivity, which facilitates the heat transfer of the second layer of glass to the second support, and heat dissipation is achieved through air convection in the first air duct, thereby ensuring the heat dissipation and cooling of the second layer of glass.
[0018] In some embodiments, the fixed support assembly further includes a fixing seat, and both ends of the first bracket and both ends of the second bracket are fixed to the door structure by the fixing seat.
[0019] Beneficial effects: The fixed base facilitates the installation of the air intake component on the door structure and ensures the positional stability of the fixed support component.
[0020] In some embodiments, the width A of the first gap satisfies A≥9mm.
[0021] Beneficial effects: By setting the width of the first gap to be greater than or equal to 9 mm, it can be ensured that the airflow is accelerated when passing through the first gap, without the air resistance being too large due to the size of the first gap being too small, thus affecting the flow.
[0022] In some embodiments, the width B of the second gap satisfies that B ≥ 5 mm.
[0023] Beneficial effects: Since a smaller width B of the second gap will result in the camera module being closer to the inner liner and the temperature rising higher, by setting the width of the second gap to be greater than or equal to 5 mm, it can be ensured that the temperature rise of the camera module meets the standard and avoid damage to the camera module due to excessive temperature rise.
[0024] In some embodiments, the camera module includes a camera, a flash, and a circuit board. The camera is mounted on the first bracket and is connected to both the first gap and the second gap. The flash is mounted on the first bracket and is connected to 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 mounted on the second bracket and is connected to the first gap.
[0025] Beneficial effects: The first and second gaps can reduce the resistance of airflow through the fixed support components, enabling rapid airflow and increased speed. When air flows through the first and second gaps, it achieves convective heat dissipation for the camera, diffuser, and circuit board, thereby reducing the temperature of the camera module. Since the camera and diffuser are closer to the first glass layer, the air flowing out through the first and second gaps simultaneously convects and dissipates heat, enhancing the heat dissipation effect. The circuit board, being far from the first glass layer, dissipates heat only through the air flowing out through the first gap.
[0026] In some embodiments, the first bracket is provided with a first mounting groove on the side facing the second bracket, the first mounting groove is connected to the first gap, and the camera and the flash are both disposed in the first mounting groove.
[0027] Beneficial effects: The design of the first mounting slot defines the available installation space, facilitating the installation of the camera and flash. It also prevents the camera and flash from obstructing the airflow through the first gap. When the air flows through the first gap, it flows into the first mounting slot, achieving convection cooling for the camera and flash mounted on it.
[0028] In some embodiments, the second bracket is provided with a second mounting groove on the side facing the first bracket, the second mounting groove is connected to the first gap, and the circuit board is disposed in the second mounting groove.
[0029] Beneficial effects: The second mounting slot defines the installation space, which facilitates the installation of the circuit board and prevents the installation of the circuit board from blocking the airflow through the first gap. When the air flows through the first gap, it flows into the second mounting slot to achieve convection heat dissipation for the circuit board mounted on it.
[0030] In some embodiments, the first mounting groove and the second mounting groove are opposite 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≥18mm.
[0031] Beneficial effects: By setting the sum C of the depth of the first mounting slot, the depth of the second mounting slot, and the width of the first gap to be greater than or equal to 18 mm, more air can be ensured to flow through the gap between the first and second mounting slots, thereby achieving overall convection heat dissipation for the camera module.
[0032] It is 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 is greater than the size of the first gap. That is, the air resistance between the first mounting groove and the second mounting groove is less than the air 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 improving the heat dissipation effect on the camera module.
[0033] In some embodiments, the first bracket has a flow guide slope on the side facing the first glass layer, the top of the flow guide slope is inclined toward the first glass layer, the bottom of the flow guide slope is inclined away from the first glass layer, and the bottom of the flow guide slope is connected to the first gap. The camera and / or the flash is vertically mounted on the flow guide slope, and there is a mating gap between the camera and the first glass layer.
[0034] Beneficial effects: The inclined design of the airflow guide facilitates the tilted installation of the camera, ensuring that the camera and / or flash are tilted towards the inside of the cooking device to capture and illuminate the food inside. At the same time, when air flows through the first gap, some air flows along the inclined airflow guide, thereby achieving convective heat dissipation for the camera and / or flash on the inclined airflow guide, carrying away the heat from the camera and / or flash, and reducing the temperature of the camera and / or flash.
[0035] In some embodiments, the distance L1 between the top of the camera lens and the first glass layer satisfies L1≥4mm.
[0036] Beneficial effect: By setting the distance L1 between the top of the camera lens and the first layer of glass to be greater than or equal to 4 mm, it is possible to ensure that the camera can capture images of the food inside, and avoid lens malfunction or damage caused by setting the distance L1 between the top of the camera lens and the first layer of glass too small.
[0037] In some embodiments, the distance L2 between the bottom of the camera lens and the first glass layer satisfies L2≥8mm.
[0038] Beneficial effect: By setting the distance L2 between the bottom of the camera lens and the first layer of glass to be greater than or equal to 8 mm, it can be ensured that the camera is at a suitable tilt angle to achieve clear shooting of the food inside, and avoid the situation where the distance L2 between the bottom of the camera lens and the first layer of glass is set too small, resulting in insufficient downward tilt angle of the camera and difficulty in shooting.
[0039] In some embodiments, the cross-sectional size of the air inlet gradually increases along the gas flow direction.
[0040] Beneficial effects: By setting the cross-sectional size of the air inlet to gradually increase along the direction of gas flow, the air flows in a gradual profile along the air inlet, which can expand the airflow range into the first air duct, thereby reducing the dead angle of the first air duct and improving the heat dissipation intensity of the door structure.
[0041] In some embodiments, the door structure further includes a top bracket, a bottom bracket, and two side brackets. The top bracket is located at the top of the first glass layer and the second glass layer, and the bottom bracket is located at the bottom of the first glass layer and the second glass layer. One of the side brackets is located on one side of the first glass layer and the second glass layer, and the other side bracket is located on the other side of the first glass layer and the second glass layer. The top bracket, the bottom bracket, the two side brackets, the first glass layer, and the second glass layer cooperate to form the first air duct, and the air inlet is located on the bottom bracket.
[0042] Beneficial effects: The top support, bottom support, and two side supports together form the door structure. When air flows from the air inlet of the bottom support through the first air duct, it achieves convective heat dissipation on the top support, bottom support, two side supports, and the first and second layers of glass, carrying away the heat generated during cooking and thus reducing the door temperature.
[0043] In some embodiments, the door structure further includes an insect-blocking plate disposed in the first air duct and opposite to the top bracket, the insect-blocking plate having air passage holes, and the air outlet being formed between the insect-blocking plate and the top bracket.
[0044] Beneficial effects: The space in the first air duct is small, making it difficult to clean when insects and other foreign objects enter. The insect-blocking plate can prevent insects and external foreign objects from entering the first air duct and causing blockage, ensuring the normal operation of the first air duct.
[0045] In some embodiments, the heat dissipation device further includes a second air duct, and the air intake of the heat dissipation fan is connected to the air outlet of the first air duct through the second air duct.
[0046] Beneficial effect: The second air duct allows the air flowing out of the first air duct to flow more effectively to the air intake of the cooling fan, forming an air circulation.
[0047] In some embodiments, the cooking apparatus includes a built-in steam oven. Attached Figure Description

[0070] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0072] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0073] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0074] The following is combined with Figures 1 to 15 The following describes embodiments of the present invention.
[0075] like Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, a cooking device is disclosed, including an inner pot 1, a door structure 2, a camera module 3, and a heat dissipation device 4. The inner pot 1 has an opening, the door structure 2 is movably disposed in the opening, the door structure 2 has a first air duct 211, an air inlet 241 communicating 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, which is installed in the inner pot 1. The air inlet and air outlet of the heat dissipation fan 41 are connected. External air flows into the first air duct 211 from the air inlet 241 under the action of the heat dissipation fan 41 to convect and dissipate heat from the camera module 3 in the first air duct 211. The air in the first air duct 211 flows to the air inlet of the heat dissipation fan 41 through the air outlet.
[0076] The cooking device of this application can draw air in through the cooling fan 41 during the cooking process, so that the outside air flows into the first air duct 211 through the air inlet 241 under negative pressure, flows through the camera module 3 and flows out to the air outlet, and finally flows to the air inlet of the cooling fan 41. This achieves convective heat dissipation for the door structure 2 and the camera module 3, avoids the camera module 3 from overheating and causing failure or damage, avoids the door structure 2 from overheating and burning the user, improves user safety, and reduces user waiting time.
[0077] This application does not limit the shape of the inner liner 1; it can be cylindrical, elliptical cylindrical, or a solid geometric shape.
[0078] The opening can be circular, elliptical, or geometric in shape; 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 liner 1. However, it is not limited to this; for example, in other embodiments, the door structure 2 may also be detachably connected to the opening.
[0080] To facilitate opening, a handle 27 is provided on the door structure 2. The handle 27 can be used to open or close the opening of the inner liner 1, making the operation convenient and effortless.
[0081] like Figures 1-3As shown, in some embodiments, the door structure 2 includes a first glass layer 21 and a second glass layer 22. The first glass layer 21 is disposed towards the inside of the inner liner 1, and the second glass layer 22 is disposed towards the outside of the inner liner 1. The first air duct 211 is located between the first glass layer 21 and the second glass layer 22.
[0082] The door structure 2 adopts a double-layer glass design, which allows users to easily observe the inside of the cooking device through the door structure 2. The double-layer glass can improve the heat insulation performance of the door structure 2, reduce heat loss during cooking, and facilitate the formation of a first air duct 211 between the first layer of glass 21 and the second layer of glass 22, which is beneficial for the convection heat dissipation of the door structure 2.
[0083] In some embodiments, the side of the first glass 21 facing the inner liner 1 is provided with a heat-insulating coating.
[0084] A heat-insulating coating is provided on the side of the first glass 21 facing the inner pot 1. The heat-insulating coating can play a heat-insulating role, reduce the heat loss of the inner pot 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 glass layer 21 is closer to the cooking cavity and can be made of low-emissivity Low-E glass, which can significantly reduce radiative heat transfer and decrease heat loss during cooking. Of course, in other embodiments, the first glass layer 21 can also be made of ordinary glass, and is not limited to this embodiment.
[0086] like Figure 3 As shown, in some embodiments, the cooking device further includes a fixed support assembly 5, which is disposed in the first air duct 211, and the camera module 3 is disposed in the fixed support assembly 5.
[0087] The fixed support component 5 facilitates the installation of the camera module 3 and ensures the stability of the camera module 3 installation.
[0088] like Figure 3 and Figure 4 As shown, in some embodiments, the fixed support assembly 5 includes a first bracket 51 and a second bracket 52, wherein the first bracket 51 is disposed in the first air duct 211 and is disposed near the first layer of glass 21, the second bracket 52 is disposed in the first air duct 211 and is disposed near the second layer of glass 22, a first gap 511 is provided between the first bracket 51 and the second bracket 52, and a camera module 3 is disposed in the first bracket 51 and / or the second bracket 52, and the camera module 3 is connected to the first gap 511.
[0089] When the air flows toward 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 accelerate the air flowing through it. That is, the air is accelerated when it flows out of the first gap 511, thereby enhancing the convective heat dissipation effect of the air on the door structure 2 and the camera module 3, which is beneficial for cooling.
[0090] It is understandable that the first bracket 51 and the second bracket 52 have their own thickness. The first bracket 51 and the second bracket 52 are set 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 becomes smaller, thereby speeding up the flow and enhancing the convection heat dissipation effect.
[0091] like Figure 6 As shown, in some embodiments, the first bracket 51 has a heat insulation function, and a second gap 512 is provided between the first bracket 51 and the first layer of glass 21, and the camera module 3 is connected to the second gap 512.
[0092] The first bracket 51 can insulate the heat of the first glass 21, thereby reducing heat loss during cooking and ensuring cooking effect. At the same time, it reduces the transfer of heat to the camera module 3 and lowers the temperature of the camera module 3. The second gap 512 set between the first bracket 51 and the first glass 21 can further facilitate convection heat dissipation for the camera module 3 and reduce the temperature at the camera 31 of the camera module 3.
[0093] Specifically, the first support 51 can be made of plastic and manufactured by injection molding. However, it is not limited to this; in other embodiments, the first support 51 can also be made of other materials that can provide thermal insulation.
[0094] In some embodiments, the second bracket 52 has a heat-conducting function, and the second bracket 52 and the second glass layer 22 are attached together.
[0095] The second support 52 has a thermal conductivity, which facilitates the heat transfer of the second glass 22 to the second support 52 and heat dissipation through the air convection of the first air duct 211, thereby ensuring the heat dissipation and cooling of the second glass 22.
[0096] Specifically, the second support 52 can be made of aluminum alloy to achieve high thermal conductivity. However, it is not limited to this; in other embodiments, the second support 52 can also be made of other materials that can provide thermal conductivity.
[0097] like Figures 3-5 As shown, in some embodiments, the fixed support assembly 5 further includes a fixing seat 53, and both ends of the first bracket 51 and both ends of the second bracket 52 are fixed to the door structure 2 by the fixing seat 53.
[0098] The mounting base 53 facilitates the installation of the air supply component on the door structure 2 and ensures the positional stability of the fixed support component 5.
[0099] Specifically, there can be two fixing bases 53. The first end of the first bracket 51 and the second bracket 52 are embedded in one of the fixing bases 53, and the second end of the first bracket 51 and the second bracket 52 are embedded in the other fixing base 53, thereby realizing the installation and positioning of the first bracket 51 and the second bracket 52.
[0100] like Figure 6 As shown, in some embodiments, the width A of the first gap 511 satisfies A≥9mm.
[0101] By setting the width of the first gap 511 to be greater than or equal to 9 mm, it can be ensured that the airflow is accelerated when passing through the first gap 511, and that the air resistance at this point is not too large due to the size of the first gap 511 being too small, thus affecting the flow.
[0102] For example, the width A of the first gap 511 can be 9mm, 10mm, 11mm, 12mm, etc., and can be set according to needs. This embodiment does not impose any restrictions.
[0103] like Figure 6 As shown, in some embodiments, the width B of the second gap 512 satisfies B≥5mm.
[0104] Since a smaller width B of the second gap 512 will result in the camera module 3 being closer to the inner liner 1 and the temperature rise being higher, by setting the width B of the second gap 512 to be greater than or equal to 5 mm, it can be ensured that the temperature rise of the camera module 3 meets the standard and avoid excessive temperature rise causing damage to the camera module 3.
[0105] For example, the width B of the second gap 512 can be 5mm, 6mm, 7mm, 8mm, etc., and can be set according to the specific needs. This embodiment does not impose any restrictions.
[0106] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the camera module 3 includes a camera 31, a flash 32, and a circuit board 33. The camera 31 is mounted on the first bracket 51 and is connected to both the first gap 511 and the second gap 512. The flash 32 is mounted on the first bracket 51 and is connected to 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 mounted on the second bracket 52 and is connected to the first gap 511.
[0107] The first gap 511 and the second gap 512 can reduce the resistance of airflow through the fixed support component 5, and realize the rapid flow and speed of air. When the air flows through the first gap 511 and the second gap 512, it realizes convective heat dissipation for the camera 31, the diffuser and the circuit board 33, thereby reducing the temperature of the camera module 3. Since the camera 31 and the diffuser are closer to the first glass 21, the air flowing out through the first gap 511 and the second gap 512 simultaneously convects and dissipates heat to enhance the heat dissipation effect. The circuit board 33 is far away from the first glass 21, so it is only dissipated by the air flowing out through the first gap 511.
[0108] like Figure 5 , Figure 6 As shown, in some embodiments, the first bracket 51 is provided with a first mounting groove 513 on the side facing the second bracket 52. The first mounting groove 513 communicates with the first gap 511, and the camera 31 and the flash 32 are both disposed in the first mounting groove 513.
[0109] The first mounting slot 513 defines the installation space, which facilitates the installation of the camera 31 and the flash 32. It also prevents the installation of the camera 31 and the flash 32 from blocking the airflow through the first gap 511. When the air flows through the first gap 511, it flows into the first mounting slot 513 to achieve convection heat dissipation for the camera 31 and the flash 32 mounted on it.
[0110] like Figure 5 , Figure 6 As shown, in some embodiments, the second bracket 52 is provided with a second mounting groove 521 on the side 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 second mounting slot 521 defines the installation space, which facilitates the installation of the circuit board 33 and prevents the installation of the circuit board 33 from blocking the airflow through the first gap 511. When the air flows through the first gap 511, it flows into the second mounting slot 521 to achieve convection heat dissipation of the circuit board 33 mounted on it.
[0112] like Figure 6 As shown, in some embodiments, the first mounting groove 513 and the second mounting groove 521 are opposite 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≥18mm.
[0113] By setting the sum C of the depth of the first mounting slot 513, the depth of the second mounting slot 521, and the width of the first gap 511 to be greater than or equal to 18 mm, more air can be ensured to flow through the gap between the first mounting slot 513 and the second mounting slot 521, thereby achieving overall convection heat dissipation for the camera module 3.
[0114] It is understood that in this embodiment, 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 is greater than the size of the first gap 511. That is, the air resistance between the first mounting groove 513 and the second mounting groove 521 is less than the air resistance of the first gap 511. When air flows, it will preferentially pass through the gap between the first mounting groove 513 and the second mounting groove 521, thereby improving the heat dissipation effect on the camera module 3.
[0115] For example, 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 can be 18mm, 19mm, 20mm, 21mm, etc., and can be set according to specific needs. This embodiment does not impose any restrictions.
[0116] Furthermore, the circuit board 33 is placed directly opposite the camera 31 and close to the second glass layer 22. On the one hand, the camera 31 can block some of the radiation from the circuit board 33, and on the other hand, it can move the circuit board 33 further away from the first glass layer 21, thereby reducing the temperature rise of the circuit board 33.
[0117] like Figure 4 As shown, in some embodiments, the first bracket 51 has a guide slope 514 communicating with the second gap 512 on the side facing the first glass layer 21. The top of the guide slope 514 is inclined towards the first glass layer 21, and the bottom of the guide slope 514 is inclined away from the first glass layer 21. The bottom of the guide slope is connected to the first gap. The camera 31 and / or the flash is vertically mounted on the guide slope 514. There is a mating gap between the camera 31 and the first glass layer 21.
[0118] The inclined guide surface 514 facilitates the tilted installation of the camera 31 and / or the flash, ensuring that the camera 31 and / or the flash 32 are tilted towards the inside of the cooking device to capture and illuminate the food inside. At the same time, when air flows through the first gap 511, some air flows along the inclined guide surface 514 through the first gap 511, thereby achieving convective heat dissipation for the camera 31 and / or the flash 32 on the inclined guide surface 514, carrying 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 that when the camera 31 and / or the flash 32 are vertically mounted on the guide slope 514, the axis of the camera 31 and / or the center line of the flash 32 are perpendicular to the guide slope 514, so as to ensure that the camera 31 and / or the flash 32 are facing the inside of the cooking device from above, so as to capture and illuminate the food inside.
[0120] In this embodiment, both the camera 31 and the flash lamp 32 are disposed on the guide slope 514. Multiple flash lamps 32 are provided and distributed on both sides of the camera 31, illuminating the interior of the cooking device when the camera 31 takes a picture, ensuring clear imaging. The lens of the camera 31 and the irradiation end of the flash lamp 32 are connected to the second gap 512, and the back of the camera 31 and the back of the flash lamp 32 are connected to the first gap 511. An opening is provided at the bottom of the guide slope 514, extending through the bottom of the first support 51. The bottom of the guide slope 514 is connected to the first gap 511 through the opening, meaning the first gap 511 is connected to the second gap 512 through the opening. Air flowing through the first gap 511 convectively cools the back of the camera 31 and the back of the flash lamp 32. Part of the air in the first gap 511 flows through the opening to the guide slope 514, convectively cooling the lens of the camera 31 and the irradiation end of the flash lamp 32, and finally converges and flows to the second gap 512, thereby achieving sufficient convective cooling for the flash lamp 32 and the camera 31.
[0121] like Figure 7 As shown, in some embodiments, the distance L1 between the top of the lens of the camera 31 and the first glass layer 21 satisfies L1≥4mm.
[0122] By setting the distance L1 between the top of the lens of the camera 31 and the first glass layer 21 to be greater than or equal to 4 mm, it is possible to ensure that the camera 31 can capture images of the food inside, and to avoid lens malfunction or damage caused by setting the distance L1 between the top of the lens of the camera 31 and the first glass layer 21 too small.
[0123] For example, the distance L1 between the top of the lens of the camera 31 and the first glass layer 21 can be 4mm, 5mm, 6mm, 7mm, etc., and can be set according to the specific needs. This embodiment does not impose any restrictions.
[0124] like Figure 7 As shown, in some embodiments, the distance L2 between the bottom of the lens of the camera 31 and the first glass layer 21 satisfies L2≥8mm.
[0125] By setting the distance L2 between the bottom of the lens of camera 31 and the first glass layer 21 to be greater than or equal to 8 mm, it can be ensured that camera 31 is at a suitable tilt angle to achieve clear shooting of the food inside, and avoid the situation where the distance L2 between the bottom of the lens of camera 31 and the first glass layer 21 is set too small, resulting in insufficient downward tilt angle of camera 31, making it difficult to take pictures.
[0126] For example, the distance L2 between the bottom of the lens of the camera 31 and the first glass layer 21 can be 8mm, 9mm, 10mm, 11mm, etc., and can be set according to the specific needs. This embodiment does not impose any restrictions.
[0127] By setting the distance between the lens of camera 31 and the first layer of glass 21, food recognition can be achieved inside the cooking device, including the type of food and the degree of food cooking. Users can remotely view the cooking process of the food inside the cooking device and remotely control the cooking device through camera 31.
[0128] With the above settings, air can flow through the lens and back of the camera 31, which can effectively reduce the lens temperature of the camera 31 from 62°C to 51°C.
[0129] like Figure 8 As shown, in some embodiments, the cross-sectional size of the air inlet 241 gradually increases along the gas flow direction.
[0130] By setting the cross-sectional dimensions of the air inlet 241 to gradually increase along the direction of gas flow, the air flows along the air inlet 241 in a gradually contoured shape, which can expand the airflow range into the first air duct 211, thereby reducing the airflow dead angle of the first air duct 211 and improving the heat dissipation intensity of the door structure 2.
[0131] Specifically, the air inlet 241 can be configured as a trumpet shape, an inverted cone shape, etc., and this embodiment does not impose specific limitations.
[0132] like Figure 2 , Figure 3 As shown, in some embodiments, the door structure 2 further includes a top support 23, a bottom support 24, and two side supports 25. The top support 23 is located at the top of the first glass layer 21 and the second glass layer 22, and the bottom support 24 is located at the bottom of the first glass layer 21 and the second glass layer 22. One side support 25 is located on one side of the first glass layer 21 and the second glass layer 22, and the other side support 25 is located on the other side of the first glass layer 21 and the second glass layer 22. The top support 23, the bottom support 24, the two side supports 25, and the first glass layer 21 and the second glass layer 22 cooperate to form a first air duct 211, and the air inlet 241 is located on the bottom support 24.
[0133] The top support 23, the bottom support 24 and the two side supports 25 together form the door structure 2. When air flows from the air inlet 241 of the bottom support 24 through the first air duct 211, it achieves convective heat dissipation on the top support 23, the bottom support 24, the two side supports 25 and the first glass layer 21 and the second glass layer 22, carrying away the heat generated during cooking, thereby reducing the door temperature.
[0134] Specifically, such as Figure 8 As shown, in order to improve air circulation, multiple air inlets 241 are arrayed on the bottom bracket 24.
[0135] Of course, in other embodiments, the air inlet 241 may also be located on the side bracket 25 or the top bracket 23, etc., and is not limited to this embodiment.
[0136] like Figure 2 , Figure 3 As shown, in some embodiments, the door structure 2 further includes an insect-blocking plate 26 disposed in the first air duct 211 and opposite to the top support 23. The insect-blocking plate 26 is provided with an air passage hole 261, and an air outlet is formed between the insect-blocking plate 26 and the top support 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 baffle 26 can prevent insects and external foreign objects from entering the first air duct 211 and causing blockage, thus ensuring the normal operation of the first air duct 211.
[0138] like Figure 9 As shown, the insect-blocking plate 26 is provided with multiple air passage holes 261 in an array to facilitate air passage and improve air circulation.
[0139] like Figure 2 As shown, in some embodiments, the heat dissipation device 4 further includes a second air duct 421, and the air intake of the heat dissipation fan 41 is connected to the air outlet of the first air duct 211 through the second air duct 421.
[0140] The second air duct 421 allows the air flowing out of the first air duct 211 to flow better to the air intake of the cooling fan 41, forming an air circulation flow.
[0141] Specifically, such as Figure 2 , Figure 3 As shown, the heat dissipation device 4 also includes a first air duct cover plate 42, and a second air duct 421 is formed inside the first air duct cover plate 42.
[0142] like Figure 2 , Figure 3 As shown, in this embodiment, the heat dissipation device 4 is further provided with a second air duct cover plate 43, and the second air duct cover plate 43 has a third air duct 431 inside. The third air duct 431 is connected to the air outlet of the heat dissipation fan 41 so that air is blown from the heat dissipation fan 41 to the third air duct 431 and blown out.
[0143] Specifically, the cooling fan 41 can be located at the top of the inner liner 1, the first air duct cover 42 is located at the top of the inner liner 1 and connected to the cooling fan 41, and the second air duct cover 43 is located at the top of the first air duct cover 42 and connected to the cooling fan 41. However, it is not limited to this. In other embodiments, the positions of the cooling fan 41, the first air duct cover 42 and the second air duct cover 43 can be set as needed.
[0144] This application uses a cooling fan 41 to drive air into the first air duct 211 through the air inlet 241, which then flows through components such as the fixed support assembly 5 and the camera module 3. The air is then drawn into the cooling fan 41 through the insect baffle 26, the air outlet, and the second air duct 421, and finally discharged from the cooking device through the third air duct 431. The advantage of this design is that the air flowing through the door structure 2 is more evenly distributed when the air is drawn in. If the air is exhausted into the first air duct 211 inside the door structure 2, the upper insect baffle 26 will block a large amount of airflow and cause turbulent airflow into the door structure 2, making it difficult to discharge from the air inlet 241 of the bottom bracket 24.
[0145] like Figures 10 to 15 As shown, to more clearly illustrate the design advantages of this application, the simulation results are presented below. Figure 10 This is a flow field distribution diagram of the air in the first air duct 211 of the cooking apparatus of this application. Figure 13 The diagram shows the airflow distribution within the first air duct 211 of a prior art cooking device. It can be seen that the air velocity increases when flowing through the fixed support assembly 5 and the camera module 3, while in the prior art, the air velocity decreases when flowing through the camera 31 due to obstruction. Furthermore, according to... Figure 11 , Figure 12 , Figure 13 and Figure 14 Analysis shows that after air convection cooling, the temperature of the camera module 3 and the door structure 2 in this application is lower than that of the camera module 3 and the door structure 2 in the prior art. In other words, the convection cooling effect of this application is better.
[0146] Analysis of guide rails 12 and 13 shows that the presence of guide rails is beneficial for enhancing heat dissipation.
[0147] In some embodiments, the cooking apparatus includes a built-in steam oven.
[0148] Of course, the cooking device is not limited to a built-in steam oven; in other embodiments, the cooking device may also include an air fryer, etc.
[0149] Although 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.
