Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a cooking device. Background Technology

[0002] With the development of smart technology, home appliances are becoming increasingly intelligent. For example, many home appliances such as microwave ovens, ovens, and steam ovens are equipped with cameras to identify the types and quantities of ingredients. The control module automatically cooks the food based on the information received from the camera, as well as parameters such as pre-stored functions and user habits.

[0003] However, in existing technologies, the camera is usually installed on the left or right side of the inner pot. This creates a blind spot for the camera when some food is close to the side of the cooking device, making it unable to recognize the real-time cooking status of the food and ultimately resulting in poor taste.

[0047] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0048] Please see Figures 1 to 13 This application provides a cooking device 100, including: a shell 10, an inner pot 20, a wind guide structure 30, an imaging device 40, a first cooling fan 50, and a second cooling fan 60.

[0049] Please refer to Figures 1 to 3 The outer shell 10 is provided with an air inlet 11 and an air outlet 12; the inner liner 20 is located inside the outer shell 10 and is provided with a cooking cavity 21; the air guide structure 30 is located above the inner liner 20 and includes an upper air guide section 31 and a lower air guide section 32. The upper air guide section 31 has an air inlet 311, an air guide cavity 312 and an air outlet 313 connected in sequence. Both ends of the lower air guide section 32 are connected to the air guide cavity 312 and are provided with an air guide channel 321; the imaging device 40 is installed at one end of the lower air guide section 32 near the air outlet 313 and is used to image the food in the cooking cavity 21; the first cooling fan 50 is provided at the air inlet 311 or the corresponding air inlet 311 and is used to drive the airflow to flow in through the air inlet 11; the second cooling fan 60 is installed in the lower air guide section 32 or the air guide cavity 312 and is used to drive the airflow in the air guide cavity 312 to flow into the air guide channel 321.

[0050] The aforementioned cooking device 100, by placing the imaging device 40 above the inner pot 20, allows the imaging device 40 to capture images of the food below in a downward direction. This avoids blind spots compared to placing the imaging device 40 on the left or right side of the inner pot 20. Simultaneously, by providing an air guide structure 30, a first cooling fan 50, and a second cooling fan 60 above the inner pot 20, the first cooling fan 50 drives airflow into the air guide cavity 312, which dissipates heat from the imaging device 40 as it flows above it. Simultaneously, driven by the second cooling fan 60, the airflow flows into the air guide channel 321 of the downward air guide section 32, directly blowing towards the imaging device 40, achieving direct heat dissipation. Thus, the airflow from both parts dissipates heat from the imaging device 40, ensuring its service life.

[0051] Understandably, please refer to Figure 3 In order to minimize the transfer of heat from the cooking cavity 21 to the imaging device 40 and other electronic components located above, the cooking device 100 may also be provided with a heat insulation pad 70. The heat insulation pad 70 is located between the air guide structure 30 and the inner liner 20 to block the transfer of heat into the air guide structure 30, thereby protecting the other electronic components installed above the heat insulation pad 70.

[0052] It should be noted that when the two ends of the lower air guide section 32 are respectively connected to the air guide cavity 312, the upper air guide section 31 is provided with a first connecting port 314 and a second connecting port 315 in sequence along the airflow direction. The first connecting port 314 corresponds to the first end of the lower air guide section 32, and the second connecting port 315 corresponds to the second end of the lower air guide section 32, thereby realizing the connection between the air guide cavity 312 and the lower air guide section 32. In this way, the airflow flows into the lower air guide section 32 from the first connecting port 314 to dissipate heat from the imaging device 40 located at the second end. The dissipated airflow flows through the second connecting port 315 to the airflow outlet 313. At the same time, the airflow flowing along the air guide cavity 312 can also flow from above the imaging device 40, dissipating heat from the imaging device 40 in a two-part manner to improve the heat dissipation effect of the imaging device 40.

[0053] In this embodiment, the cooking device 100 can be a household appliance such as an oven, microwave oven, baking oven, or microwave steam oven.

[0054] Please see Figures 4 to 7To achieve a compact structure, the air guide structure 30 in this embodiment not only dissipates heat from the imaging device 40, but also, in the X direction, includes a first mounting portion 316 and two air inlets 317 located at both ends of the first mounting portion 316. The lower air guide portion 32 and the second cooling fan 60 are mounted on the first mounting portion 316. The two air inlets 317 are defined as the first air inlet 3171 and the second air inlet 3172, respectively. The cooking device 100 also includes electronic components and a third cooling fan 90. The first cooling fan 50 is located in the first air inlet 3171, and the electronic components and the third cooling fan 90 are located in the second air inlet 3172. Thus, by setting up the two air inlets 317, the entire air guide structure 30 not only dissipates heat from the imaging device 40, but also simultaneously exhausts the airflow after the other electronic components have been cooled. This reduces the need for separate air guide components to dissipate heat from the electronic components, making the entire cooking device 100 more compact and allowing for efficient use of the installation space above the inner pot 20.

[0055] When installing the electronic components and the third cooling fan 90, the third cooling fan 90 can be connected to the second air inlet 3172 along the Y direction, and the electronic components can be located outside the air inlet 317; or the third cooling fan 90 and the electronic components can both be located outside the air inlet 317, and the second air inlet 3172, the electronic components and the third cooling fan 90 can be arranged sequentially along the Y direction. In this way, the air driven by the third cooling fan 90 can flow directly to the electronic components, and the airflow that cools the electronic components also flows into the air guide cavity 312 through the air inlet 317, and finally flows out through the air outlet 313.

[0056] Please refer to Figure 4 and Figure 5 In this embodiment, the electronic component can be a magnetron 80, a main control module, or a frequency converter 200 that controls the magnetron 80. Specifically, the cooking device 100 in this embodiment is described using a microwave steam oven as an example. The electronic component in this embodiment is a magnetron 80, which is used to generate microwaves and introduce them into the cooking cavity 21 to heat the food.

[0057] Understandably, since the magnetron 80 needs to be controlled, the cooking device 100 also includes an inverter 200. Along the Y direction, the air inlet 317, the magnetron 80, the inverter 200 and the third cooling fan 90 are arranged in sequence, so that the airflow driven by the third cooling fan 90 flows through the inverter 200 and the magnetron 80 in sequence and then flows into the second air inlet 3172, thereby achieving heat dissipation for the inverter 200 and the magnetron 80.

[0058] Therefore, the upper air guide section 31 of this embodiment achieves compact installation between structures by providing two air inlets 317, which can simultaneously dissipate heat from the imaging device 40, as well as from the magnetron 80 and the frequency converter 200, thus achieving multiple heat dissipation effects.

[0059] Understandably, since microwaves need to be introduced into the inner liner 20, the inner liner 20 needs to be provided with a microwave inlet. In order to further achieve a compact structure, the center of the inner liner 20 is the microwave inlet. The first mounting part 316 is located in front of the microwave inlet along the Y direction, and the two air inlets 317 are arranged around the left and right sides of the inlet along the X direction. In this way, the first mounting part 316 and the two air inlets 317 are arranged around the three sides of the microwave inlet to make reasonable use of the installation space above the inner liner 20.

[0060] It should be noted that "front" refers to the side of the cooking device 100 that is closest to the user when in use, "left" corresponds to the user's left side, and "right" corresponds to the user's right side.

[0061] In another embodiment, the first mounting part 316 may be positioned corresponding to the rear side of the microwave inlet, and the air inlets 311 of the two air inlets 317 may be positioned facing the front side of the cooking device 100. This can also achieve the effect of the first mounting part 316 and the two air inlets 317 surrounding the three sides of the microwave inlet, thus achieving a reasonable layout between the components.

[0062] In addition, please see Figure 8 , Figure 10 as well as Figure 11 Based on the installation of the imaging device 40 and the cooling of the imaging device 40, and / or the installation of the magnetron 80 and the cooling of the magnetron 80, since steam is generated during the cooking process, in order to facilitate the exhaust of steam, the upper air guide section 31 of this embodiment is also provided with a steam port 318, which is connected to the air guide cavity 312. In this way, the air guide structure 30 can not only guide the air to cool the imaging device 40, but also the airflow can exhaust the steam flowing out of the steam port 318. One air guide structure 30 achieves multiple effects, which is conducive to the compactness and miniaturization of the entire cooking device 100.

[0063] Understandably, since the steam outlet 318 emits steam with a certain humidity, in order to prevent the steam from corroding the imaging device 40, the first connecting port 314 and the steam outlet 318 are arranged sequentially along the airflow direction. The bottom wall of the upper air guide section 31 is provided with a partition rib 319, which is located between the steam outlet 318 and the second connecting port 315 and extends towards one side of the first air inlet section 3171. Thus, since the first connecting port 314 and the steam outlet 318 are arranged sequentially along the airflow direction, when the airflow flows in from the airflow inlet 311, it can flow through the first connecting port 314 and the steam outlet 318 in sequence, thereby preventing the steam from flowing into the first connecting port 314. Therefore, by setting the partition rib 319 between the second connecting port 315 and the steam outlet 318, the steam is blocked from flowing into the second connecting port 315, thus preventing corrosion of the imaging device 40.

[0064] It should be noted that in this embodiment, the first connecting port 314 and the steam port 318 are arranged sequentially along the direction of airflow inflow, meaning that they are arranged sequentially from the airflow inlet 311 to the airflow outlet 313, so that the airflow flows through the first connecting port 314 and the steam port 318 in sequence.

[0065] Furthermore, the partition rib 319 can also be configured to abut against the top of the upper air guide section 31, thereby supporting the upper air guide section 31 and ensuring the structural strength of the entire upper air guide section 31.

[0066] Specifically, please refer to Figure 11 In order to ensure that the steam port 318 and the second connecting port 315 have a certain airflow, the steam port 318 is set to correspond to the airflow inlet 311. The partition rib 319 extends to one side of the airflow inlet 311 and is close to the first cooling fan 50. It is set at an angle relative to the airflow direction and is set at an angle from the second connecting port 315 to the steam port 318. Since the steam port 318 is set to correspond to the airflow inlet 311, in order to make a certain amount of airflow flow towards the second connecting port 315, the partition rib 319 is set at an angle relative to the airflow direction. The airflow flowing in from the airflow inlet 311 is divided into two parts. One part flows to one side of the second connecting port 315, and the other part flows to one side of the first connecting port 314 and the steam port 318, ensuring that both the second connecting port 315 side and the steam port 318 side can have a certain amount of airflow.

[0067] Specifically, in this embodiment, the partition rib 319 extends to one side of the first air inlet 3171. Since the first mounting part 316 and the first air inlet 3171 are arranged along the Y direction, the part of the partition rib 319 located in the first air inlet 3171 has an angle relative to the Y direction, so as to achieve the effect of diverting the airflow.

[0068] Specifically, the partition rib 319 includes a first air guide section 3191 and a partition section 3192. At least part of the first air guide section 3191 is provided in the first air inlet 3171, and the partition section 3192 is provided in the first mounting part 316. The extension direction of the first air guide section 3191 has an acute angle with the Y direction, which means that the first air guide section 3191 is inclined in the first air inlet 3171 so as to separate and guide the airflow flowing in from the air inlet 311 to the second connecting port 315 and the steam port 318, so that the second connecting port 315 and the steam port 318 can guarantee a certain amount of air intake.

[0069] Furthermore, in order to ensure the air intake volume of the airflow inlet 311, the upper air guide portion 31 of this embodiment has an arched area 36 and a planar support area 37. The height of the arched area 36 in the vertical direction is greater than the height of the planar support area 37 in the vertical direction. The arched area 36 forms the airflow inlet 311. By setting a higher arched area 36, ​​the cross-sectional area of ​​the airflow inlet 311 in the vertical direction can be increased, thereby allowing for a larger first cooling fan 50 to be installed, ensuring sufficient air intake volume and ensuring the heat dissipation effect on the imaging device 40.

[0070] Specifically, please refer to Figure 6 In this embodiment, the upper air guide section 31 includes a detachably connected upper air guide plate 33 and a lower air guide plate 34. The lower air guide plate 34 is provided with the aforementioned partition rib 319, a first connecting port 314, a second connecting port 315, and a steam port 318. The upper air guide plate 33 includes an arched section 331 and a flat section 332. The arched section 331 and the lower air guide plate 34 surround each other to form an airflow inlet 311. Thus, the detachably connected upper air guide plate 33 and lower air guide plate 34 facilitate the assembly of the entire upper air guide section 31, and the individually formed upper air guide plate 33 and lower air guide plate 34 can be formed into different irregular structures corresponding to the installation space above the inner liner 20.

[0071] Therefore, corresponding to the airflow inlet 311 with a certain height, in order for the first air guide section 3191 to achieve the function of air distribution, the first air guide section 3191 in this embodiment includes a first section 3191a and a second section 3191b with different heights. The first section 3191a is close to the airflow inlet 311, and the height of the first section 3191a is greater than the height of the second section 3191b. In this way, by setting the higher first section 3191a, when the airflow flows in from the airflow inlet 311, it can be separated and flow to both sides of the dividing section 3192, achieving a good air distribution effect.

[0072] In one embodiment, when a first segment 3191a and a second segment 3191b with different heights are set, the second segment 3191b and the dividing segment 3192 can be set to have the same height, or the height of the second segment 3191b in the direction away from the first segment 3191a can be set to gradually decrease until it connects with the dividing segment 3192. Both of these settings can achieve the effect of dividing and guiding the first air guide segment 3191.

[0073] Further, please refer to Figure 11 In winter, high-temperature steam flowing out from the air outlet 12 will condense when it encounters cold air. A large amount of condensed steam will affect the user experience. Therefore, multiple air guide ribs 35 are provided on the inner wall of the upper air guide section 31. The air guide ribs 35 extend from the steam port 318 to the air outlet 313. The multiple air guide ribs 35 are arranged in parallel with the partition ribs 319 along the X direction. The partition ribs 319 and the air guide ribs 35, as well as between each two adjacent air guide ribs 35, form a steam exhaust channel 345. By setting multiple steam exhaust channels 345, the steam can be dispersed when it is discharged from the outer shell 10, avoiding it from being sprayed out in an explosive manner. For example, when using the cooking device 100 in winter, it can prevent the high-temperature steam from liquefying in the cold air and producing a large amount of condensed water, which would affect the user experience.

[0074] Specifically, please refer to Figure 11 In this embodiment, when forming the airflow outlet 313, the lower air guide plate 34 includes a second mounting portion 342 and an air outlet portion 343 along the Y direction. The second mounting portion 342 and the air outlet portion 343 are arranged perpendicularly along the Y direction. The air outlet portion 343 itself forms the airflow outlet 313. The second mounting portion 342 is provided with a first connecting port 314, a second connecting port 315, and a steam port 318. Thus, the upper air guide plate 33 overlaps with the air outlet portion 343 to realize the flow of airflow to the side of the airflow outlet 313. In this way, the lower air guide plate 34 itself forms the airflow outlet 313, which makes it easier for the lower air guide plate 34 to be formed into the required shape of the air outlet structure. In other embodiments, the airflow outlet 313 can also be formed by the upper air guide plate 33 and the lower air guide plate 34 together.

[0075] Furthermore, corresponding to the way that the air outlet 313 is formed by the air outlet 343, when the air guide rib 35 is set, the air outlet 343 has a certain height in the vertical direction, so that the partition rib 319 and / or the air guide rib 35 extends to the edge of the lower air guide plate 34, that is, the partition rib 319 and / or the air guide rib 35 extends to the air outlet 343. In this way, the second connecting port 315 and the steam port 318 are completely separated. After the airflow passes through the second connecting port 315 and the steam port 318, they each flow to the air outlet 313 through their corresponding channels.

[0076] When the partition rib 319 and / or the air guide rib 35 extend to the edge of the lower air guide plate 34, the partition rib 319 may extend to the edge of the lower air guide plate 34, or the air guide rib 35 may extend to the edge of the lower air guide plate 34, or both the partition rib 319 and the air guide rib 35 may extend to the edge of the lower air guide plate 34.

[0077] Further, please refer to Figure 11 When the air outlet 313 is formed by the lower air guide plate 34 itself, the air outlet 343 includes multiple air outlets 313. A partition plate 344 is provided between each pair of adjacent air outlets 313. A guide rib 35 and a partition plate 344 are provided accordingly. In this way, a steam exhaust channel 345 is formed between each pair of adjacent guide ribs 35. A steam exhaust channel 345 corresponds to an air outlet 313, so that the steam can be dispersed when it is discharged from the outer casing 10, avoiding it from being ejected in an explosive manner.

[0078] Specifically, when setting the air guide ribs 35, some of the air guide ribs 35 extend from the steam port 318 to the side of the air outlet 313. One of the air guide ribs 35 is set in the X direction between the steam port 318 and the side wall of the lower air guide plate 34, so that the adjacent air guide ribs 35 extending from the steam port 318 to the side of the air outlet 313 form a steam exhaust channel 345. The air guide rib 35 set between the steam port 318 and the side wall of the lower air guide plate 34 has a blocking function to prevent steam from overflowing to the edge of the lower air guide plate 34. At the same time, it also has a guiding function to allow the airflow flowing from the air inlet 311 to flow to the side of the steam port 318.

[0079] Please see Figure 11 To guide the steam discharged from the steam outlet 318 towards the airflow outlet 313 as much as possible, a first airflow guide rib 35 is defined as the airflow guide rib located between the side wall of the lower airflow guide plate 34 and the steam outlet 318 along the X direction. The first airflow guide rib includes a second airflow guide section 351 and a third airflow guide section 352. The second airflow guide section 351 and the third airflow guide section 352 are set at an angle, and the second airflow guide section 351 is inclined to the side away from the steam outlet 318. In this way, by setting the second airflow guide section 351 inclined to the side away from the steam outlet 318, the distance between it and the steam outlet 318 is increased, which is equivalent to expanding the airflow opening, so as to guide more airflow from the airflow inlet 311 into the space between the steam outlet 318 and the second airflow guide section 351, thereby improving the steam discharge effect. By setting the third airflow guide section 352, a steam exhaust channel 345 is formed between it and the adjacent airflow guide rib 35, achieving the effect of exhausting steam and airflow.

[0080] Furthermore, based on the location of the steam inlet 318 and the air outlet 313, the third air guide section 352 is arc-shaped and bent towards the side wall of the downward air guide plate 34 in the X direction, so that the third air guide section 352 can have sufficient spacing with the adjacent air guide rib 35, that is, the air outlet 313 corresponding to the steam channel 345 can have sufficient width in the X direction to ensure the air outlet effect.

[0081] Understandably, please refer to Figure 11 When the upper air guide plate 33 and the lower air guide plate 34 have a certain coverage area, in order to prevent the upper air guide plate 33 from collapsing after the side facing away from the lower air guide plate 34 is supported by an object, the lower air guide plate 34 is provided with at least one support rib 341 on the side facing the upper air guide plate 33. The support rib 341 and the upper air guide plate 33 abut against each other. That is, the support rib 341, the air guide rib 35 and the partition rib 319 work together to support the upper air guide plate 33 and prevent the upper air guide plate 33 from collapsing.

[0082] Specifically, after setting the support rib 341, the air guide rib 35 and the partition rib 319, the air guide cavity 312 is divided into three parts. Along the X direction, the leftmost part corresponds to the heat dissipation channel of the electronic components, the middle area corresponds to the heat dissipation channel of the imaging device 40, and the right side of the partition rib 319 corresponds to the steam exhaust channel.

[0083] In addition, for a more compact use of the structure, please refer to Figure 4 and Figure 5 The cooking device 100 in this embodiment also includes a water tank 300, which provides moisture to the food during the cooking process. The water tank 300 is located in the planar support area 37 of the upper air guide section 31 to make full use of the clearance space formed by the upper air guide section 31 and achieve compact installation between components.

[0084] Furthermore, the arched area 36 has an inclined portion, which can be used to mount a circuit board 500, such as a circuit board 500 for opening the water tank 300 or controlling the display screen, so as to make full use of the mounting space formed in the arched area 36.

[0085] Please refer to Figure 10 In this embodiment, the upper air guide plate 33 and the lower air guide plate 34 are installed by interlocking with each other, which not only achieves positioning and installation but also ensures a certain overlap area between them, thus guaranteeing airtightness. Furthermore, the lower air guide plate 34 is provided with a first mounting post 346, and the upper air guide plate 33 is provided with a second mounting post 333. The first mounting post 346 and the second mounting post 333 are connected by bolts, thereby achieving stable installation of the entire upper air guide structure 30.

[0086] Please see Figures 8 to 10When the first cooling fan 50 and the second cooling fan 60 are set, the first cooling fan 50 is set vertically, and the second cooling fan 60 is set horizontally at the first connecting port 314. In this way, the first cooling fan 50, which is set vertically, can ensure the air intake volume, and the second cooling fan 60, which is set horizontally, does not occupy the space in the air guide cavity 312, and can also achieve the effect of guiding the airflow from the air guide cavity 312 to the lower air guide part 32. Compared with the method of setting the second cooling fan 60 vertically, the vertical height occupied is reduced, thereby realizing the miniaturization of the entire cooking device 100 in the vertical direction, and also avoiding resistance to the airflow.

[0087] Please see Figure 10 When the first cooling fan 50 is installed, an installation structure 334 is provided on the inner wall of the upper air guide plate 33. The installation structure 334 is used to limit the installation of the first cooling fan 50. Thus, when the first cooling fan 50 is installed, it is pushed into the air guide cavity 312 in the direction of the installation structure 334. When it contacts the installation structure 334, the installation position of the first cooling fan 50 is limited.

[0088] In one embodiment, the mounting structure 334 may be a limiting block provided on the inner wall of the upper air guide plate 33, thereby abutting against the first cooling fan 50 to limit the first cooling fan 50; specifically, the mounting structure 334 of this embodiment is provided with a slot 335, and the first cooling fan 50 is locked in the slot 335 to limit the first cooling fan 50, and then it can be installed by bolts and the lower air guide plate 34.

[0089] Further, please refer to Figure 9 The lower air guide plate 34 has a third mounting post 347 at its end, with a first mounting hole 348 on the third mounting post 347. The first cooling fan 50 has a second mounting hole 51. The first mounting hole 348 and the second mounting hole 51 are connected by bolts. Thus, by providing mounting holes, the first cooling fan 50 is installed at the end of the lower air guide plate 34. In other embodiments, the lower air guide plate 34 and the first cooling fan 50 can be connected by plugging or snapping to achieve detachable installation of the first cooling fan 50, thereby facilitating disassembly and maintenance in case of subsequent failure of the first cooling fan 50.

[0090] Please see Figure 9To facilitate the installation of the first cooling fan 50, a limiting structure 349 is provided on the lower air guide plate 34. The limiting structure 349 and the third mounting post 347 are separated and used to limit the installation of the cooling fan. That is, the installation position of the first cooling fan 50 is limited by the cooperation of the limiting structure 349 and the third mounting post 347, which facilitates the subsequent locking of the bolts.

[0091] Please see Figure 12 The diagram below shows the structure of the lower air guide portion 32 in this embodiment. The lower air guide portion 32 includes a receiving portion 322 and an air guide portion 323. The receiving portion 322 is provided with a receiving cavity 324 and a third connecting port 325. The receiving cavity 324 is used to install the imaging device 40. The third connecting port 325 is connected to the second connecting port 315. The air guide portion 323 forms an air guide channel 321.

[0092] When setting the lower air guide 323, in order to adapt to the installation of other components within the entire cooking device 100, the width of the air guide 323 gradually decreases from the receiving part 322 toward the second cooling fan 60. On the one hand, the gradually decreasing width of the air guide 323 can accommodate the smaller width of the second cooling fan 60, and the smaller width of the second cooling fan 60 occupies less installation space, thereby achieving a compact installation with other components. On the other hand, the width gradually increases toward the receiving part 322, so that the airflow driven by the second cooling fan 60 can be dispersed onto the imaging device 40, carrying away more heat from the imaging device 40 and achieving a better heat dissipation effect.

[0093] Furthermore, when the second cooling fan 60 and the lower air guide 323 are connected, they can be connected by overlapping. For example, the air outlet 61 of the second cooling fan 60 can be placed on the end of the air guide 323 so that the airflow from the second cooling fan 60 can flow into the air guide 323.

[0094] Understandably, please refer to Figure 8 In order to prevent excessive heat from radiating towards the imaging device 40 during the cooking process, the lower air guide plate 34 is provided with a frame 349a surrounding the housing 322. The frame 349a can block the transfer of heat from the surrounding area to the imaging device 40, thereby further achieving the protection effect of the imaging device 40.

[0095] Please see Figure 12 and Figure 13In this embodiment, the imaging device 40 is set off from the center of the inner liner 20 to avoid the microwave inlet. At the same time, in order to ensure that the imaging device 40 has a large imaging range and avoid blind spots, the imaging surface 44 of the imaging device 40 is set at an angle to the horizontal plane. That is, the camera 42 is not set vertically downward, but tilted towards the food, thereby having a wider imaging range 400.

[0096] Please refer to Figure 13 The imaging device 40 includes a mounting plate 41, a camera 42 disposed on one side of the mounting plate 41, and heat dissipation fins 43 disposed on the other side of the mounting plate 41. In this embodiment, the imaging surface 44 of the imaging device 40 refers to the shooting surface of the camera 42, and the shooting surface is set at an angle to the horizontal plane.

[0097] In one implementation, multiple heat dissipation fins 43 can be provided, and the gaps between the heat dissipation fins 43 can be oriented towards the direction of airflow, so that the airflow can carry away heat when it flows through the gaps between the heat dissipation fins 43. Alternatively, in another embodiment, the extension direction of the heat dissipation fins 43 can be set perpendicular to the direction of airflow, which can also achieve the heat dissipation effect on the camera 42.

[0098] Specifically, when the imaging device 40 is tilted, the angle θ between the imaging surface 44 of the imaging device 40 and the horizontal plane is in the range of 15-25°. Specifically, the surface of the camera 42 has an angle of 15-25° with the horizontal plane so that the camera 42 is oriented toward the food to ensure the imaging range 400.

[0099] In some embodiments, depending on the amount of food being photographed, the angle between the camera 42 and the horizontal plane can be set to 15°, 18°, 21°, 23° or 25°, etc., and is not limited thereto.

[0100] Because the imaging device 40 has an angle relative to the horizontal plane, in order to stably install the imaging device 40, the receiving part 322 has a support surface 326 for the imaging device 40. The support surface 326 and the imaging device 40 have the same tilt angle so as to support the camera 42 of the imaging device 40 and avoid it from being suspended. Understandably, the support surface 326 is provided with a light hole 327 so that the imaging device 40 can achieve the imaging effect.

[0101] Understandably, by setting the lower air guide section 32 at the bottom of the upper air guide section 31, not only can the imaging device 40 be guided, but the lower air guide section 32 also has a certain height, which is equivalent to giving a gap between the lower air guide section 32 and the heat insulation pad 70, so as to further reduce the transfer of heat from the cooking cavity 21 to the air guide cavity 312.

[0102] The cooking device 100 described above achieves multiple air-guiding effects by providing two air inlets 317 in the X direction on the upper air guide section 31. One air inlet 317 can supply air to the steam port 318 and the imaging device 40, while the other air inlet 317 can circulate the airflow after cooling electronic components such as the magnetron 80. By setting the first cooling fan 50 vertically, a larger size of the first cooling fan 50 can be installed to ensure the air intake of the entire air guide structure 30. The second cooling fan 60 is set horizontally to reduce the vertical height of the entire air guide structure 30 and the second cooling fan 60. By setting the imaging device 40 at an angle relative to the horizontal plane, the imaging range 400 is ensured, avoiding blind spots in the shooting.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
