[0024] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0025] See also Figures 1 to 13 An embodiment of the present application provides a cooking device 100 , including: a shell 10 , an inner pot 20 , an air guide structure 30 , an imaging device 40 , a first cooling fan 50 , and a second cooling fan 60 .

[0026] Among them, see Figures 1 to 3The outer shell 10 is provided with an air inlet 11 and an air outlet 12; the inner pot 20 is provided in the outer shell 10 and is provided with a cooking cavity 21; the air guide structure 30 is located above the inner pot 20, and includes an upper air guide part 31 and a lower air guide part 32, the upper air guide part 31 has an air flow inlet 311, an air guide cavity 312 and an air flow outlet 313 connected in sequence, and both ends of the lower air guide part 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 part 32 close to the air flow outlet 313, and is used to image the food in the cooking cavity 21; the first cooling fan 50 is provided at the air flow inlet 311 or corresponding to the air flow inlet 311, and is used to drive the air flow to flow in through the air inlet 11; the second cooling fan 60 is installed in the lower air guide part 32 or the air guide cavity 312, and is used to drive the air flow in the air guide cavity 312 to flow into the air guide channel 321.

[0027] The above-mentioned cooking device 100, by arranging the imaging device 40 above the inner pot 20, the imaging device 40 shoots the food below in a downward manner, avoiding blind spots in shooting compared to the method of arranging the imaging device 40 on the left or right side of the inner pot 20; at the same time, by arranging the air guide structure 30, the first cooling fan 50 and the second cooling fan 60 above the inner pot 20, the first cooling fan 50 drives the airflow to flow into the air guide cavity 312, and when flowing along the top of the imaging device 40, it can dissipate heat for the imaging device 40; at the same time, driven by the second cooling fan 60, the airflow can flow into the air guide channel 321 of the lower air guide part 32 to directly blow towards the imaging device 40, thereby realizing direct heat dissipation of the imaging device 40. In this way, the airflow of the two parts dissipates heat for the imaging device 40, thereby ensuring the service life of the imaging device 40.

[0028] Understandably, see Figure 3 In order to minimize the transfer of heat in the cooking cavity 21 to the imaging device 40 and other electronic components located above, the cooking device 100 can also be provided with a heat insulation pad 70. The heat insulation pad 70 is arranged between the air guide structure 30 and the inner pot 20 to block the transfer of heat into the air guide structure 30, thereby protecting other electronic components installed above the heat insulation pad 70.

[0029] It should be noted that when the two ends of the lower air guide part 32 are respectively communicated with the air guide cavity 312, the upper air guide part 31 is sequentially provided with a first communication port 314 and a second communication port 315 along the flow direction of the air flow, the first communication port 314 is communicated with the first end of the lower air guide part 32, and the second communication port 315 is communicated with the second end of the lower air guide part 32, so as to realize the communication between the air guide cavity 312 and the lower air guide part 32. In this way, the air flow flows into the lower air guide part 32 from the first communication port 314, and the imaging device 40 located at the second end is cooled, and the cooled air flow flows to the air outlet 313 through the second communication port 315, and the air flow flowing in the air guide cavity 312 can also flow from above the imaging device 40, so that the imaging device 40 is cooled in two parts, so as to improve the cooling effect of the imaging device 40.

[0030] In this embodiment, the cooking device 100 can be an oven, a microwave oven, a baking all-in-one machine, or a microwave steaming and baking all-in-one machine, etc.

[0031] Please refer to Figures 4 to 7 In order to realize the compactness of the structure, the air guide structure 30 of the present embodiment can not only cool the imaging device 40 when installed, specifically, the upper air guide part 31 includes a first mounting part 316 and two air inlet parts 317 arranged at both ends of the first mounting part 316 along the X direction, the lower air guide part 32 and the second cooling fan 60 are mounted on the first mounting part 316, and the two air inlet parts 317 are defined as a first air inlet part 3171 and a second air inlet part 3172; the cooking device 100 further includes electronic components and a third cooling fan 90; the first cooling fan 50 is arranged in the first air inlet part 3171, and the electronic components and the third cooling fan 90 are arranged in the second air inlet part 3172 in sequence. In this way, by arranging the two air inlet parts 317, the entire air guide structure 30 not only cools the imaging device 40, but also guides the air flow after cooling other electronic components, reducing the installation of separate air guide components for cooling electronic components, making the structure of the entire cooking device 100 more compact, and reasonably utilizing the installation space above the inner container 20.

[0032] In this embodiment, the cooking device 100 can be an oven, a microwave oven, a baking all-in-one machine, or a microwave steaming and baking all-in-one machine, etc.

[0033] Wherein, please refer to Figure 4 and Figure 5 The electronic component of the embodiment can be a magnetron 80, or a master control module, or a frequency converter 200 for controlling the magnetron 80, etc. Specifically, the cooking device 100 is taken as an example of a microwave steaming and baking all-in-one machine, and the electronic component of the embodiment is a magnetron 80 for generating microwaves to be introduced into the cooking cavity 21 to heat food.

[0034] As can be understood, since the magnetron 80 needs to be controlled, the cooking device 100 further comprises a frequency converter 200, and along the Y direction, the air inlet part 317, the magnetron 80, the frequency converter 200, and the third heat dissipation fan 90 are sequentially arranged, so that the air flow driven by the third heat dissipation fan 90 sequentially flows through the frequency converter 200 and the magnetron 80 and then flows into the second air inlet part 3172, thereby achieving heat dissipation of the frequency converter 200 and the magnetron 80.

[0035] Therefore, the upper air guide part 31 of the embodiment achieves compact installation between structures by being provided with two air inlet parts 317, can simultaneously dissipate heat for the imaging device 40, and can also dissipate heat for the magnetron 80 and the frequency converter 200, achieving multiple heat dissipation effects.

[0036] As can be understood, since microwaves need to be introduced into the inner container 20, the inner container 20 needs to be provided with a microwave inlet, and in order to further achieve compactness of the structure, the center of the inner container 20 is the microwave inlet, the first mounting part 316 is arranged on the front side of the microwave inlet along the Y direction, and the two air inlet parts 317 are arranged on the left and right sides of the inlet along the X direction, so that the first mounting part 316 and the two air inlet parts 317 are arranged on three sides of the microwave inlet to reasonably utilize the mounting space above the inner container 20.

[0037] It should be noted that the front side refers to the side of the cooking device 100 close to the user during use, the left side corresponds to the left side of the user, and the right side corresponds to the right side of the user.

[0038] In another embodiment, the first mounting part 316 can also be arranged corresponding to the rear side of the microwave inlet, and the air flow inlets 311 of the two air inlet parts 317 are arranged towards the front side of the cooking device 100, which can also achieve the effect of the first mounting part 316 and the two air inlet parts 317 being arranged on three sides of the microwave inlet, and achieve reasonable layout between components.

[0039] In addition, please refer to Figure 8 , Figure 10 and Figure 11On the basis of providing the imaging device 40 and dissipating the heat for the imaging device 40, and / or providing the magnetron 80 and dissipating the heat for the magnetron 80, since steam is generated during the cooking process of food, in order to facilitate the discharge of steam, the upper air guide portion 31 of this embodiment is further provided with a steam port 318, and the steam port 318 is communicated with the air guide cavity 312. In this way, the air guide structure 30 can not only guide the air and dissipate the heat for the imaging device 40, but also the flow of air can discharge the steam flowing out of the steam port 318. One air guide structure 30 achieves multiple effects, which is conducive to realizing the compactness and miniaturization of the entire cooking device 100.

[0040] It can be understood that since the steam outlet 318 flows out 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 in sequence along the inflow direction of the wind flow; a separating rib 319 is provided on the bottom wall of the upper air guide portion 31, and the separating rib 319 is provided between the steam outlet 318 and the second connecting port 315, and extends toward one side of the first air inlet 3171. In this way, since the first connecting port 314 and the steam outlet 318 are arranged in sequence along the flow direction of the wind flow, when the wind flow flows in from the wind flow 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, a separating rib 319 is provided between the second connecting port 315 and the steam outlet 318 to block the steam from flowing into the second connecting port 315, thereby preventing the imaging device 40 from corroding.

[0041] It should be noted that the first communication port 314 and the steam port 318 of this embodiment are arranged in sequence along the inflow direction of the wind, that is, they are arranged in sequence from the wind inlet 311 to the wind outlet 313, so that the wind flows through the first communication port 314 and the steam port 318 in sequence.

[0042] Furthermore, the separation rib 319 can also be configured to abut against the top of the upper air guiding portion 31 , thereby supporting the upper air guiding portion 31 and ensuring the structural strength of the entire upper air guiding portion 31 .

[0043] Specifically, see Figure 11315 , the steam outlet 318 is provided with a certain amount of air flow to the steam outlet 318 and the second connecting port 315 respectively, the steam outlet 318 is provided corresponding to the air flow inlet 311, and the dividing rib 319 extends toward one side of the air flow inlet 311 and is close to the first cooling fan 50, and is provided at an angle relative to the air inlet direction, and is provided at an angle from the second connecting port 315 toward the steam outlet 318. In this way, since the steam outlet 318 is provided corresponding to the air flow inlet 311, in order to make a certain amount of air flow toward the second connecting port 315, the dividing rib 319 is provided at an angle relative to the air inlet direction, and the air flow flowing in from the air flow inlet 311 is divided into two parts, one part flows toward the side of the second connecting port 315, and the other part flows toward the side of the first connecting port 314 and the steam outlet 318, ensuring that both the side of the second connecting port 315 and the side of the steam outlet 318 can have a certain amount of air flow.

[0044] Specifically, the separating rib 319 of this embodiment extends toward one side of the first air inlet portion 3171. Since the first mounting portion 316 and the first air inlet portion 3171 are arranged along the Y direction, the portion of the separating rib 319 located at the first air inlet portion 3171 has an angle relative to the Y direction, so as to achieve the effect of diverting the airflow.

[0045] Specifically, the separating rib 319 includes a first air guide section 3191 and a separating section 3192. At least part of the first air guide section 3191 is arranged on the first air inlet portion 3171, and the separating section 3192 is arranged on the first mounting portion 316. The extension direction of the first air guide section 3191 and the Y direction have an acute angle, which is equivalent to the first air guide section 3191 being tilted in the first air inlet portion 3171 to separate the airflow flowing in from the airflow inlet 311 and guide it to the second connecting port 315 and the steam port 318, so that the second connecting port 315 and the steam port 318 are guaranteed to have a certain amount of air intake.

[0046] 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 plane support area 37. The height of the arched area 36 along the vertical direction is greater than the height of the plane support area 37 along the vertical direction. The arched area 36 forms the airflow inlet 311, so that the higher arched area 36 is set, which can increase the cross-sectional area of ​​the airflow inlet 311 along the vertical direction, so that a larger first cooling fan 50 can be set to ensure sufficient air intake volume and ensure the heat dissipation effect on the imaging device 40.

[0047] Specifically, see Figure 6In this embodiment, the upper air guide portion 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 above-mentioned dividing rib 319, the first connecting port 314, the second connecting port 315 and the steam port 318. The upper air guide plate 33 includes an arched section 331 and a plane section 332. The arched section 331 and the lower air guide plate 34 are arranged to form an airflow inlet 311. In this way, the detachably connected upper air guide plate 33 and the lower air guide plate 34 facilitate the assembly of the entire upper air guide portion 31, and the separately formed upper air guide plate 33 and the lower air guide plate 34 can be formed into different special-shaped structures corresponding to the installation space above the inner liner 20.

[0048] Therefore, corresponding to the wind inlet 311 with a certain height, in order to enable the first air guide section 3191 to achieve the wind separation function, the first air guide section 3191 of this embodiment includes a first section 3191a and a second section 3191b with different heights. The first section 3191a is close to the wind inlet 311, and the height of the first section 3191a is greater than the height of the second section 3191b. In this way, a higher first section 3191a is set. When the wind flows in from the wind inlet 311, it can be separated and flow to both sides of the partition section 3192, thereby achieving a good wind separation effect.

[0049] In one embodiment, when setting the first section 3191a and the second section 3191b with different heights, the second section 3191b and the partition section 3192 can be set to have the same height, or the height of the second section 3191b can be set to gradually decrease in the direction away from the first section 3191a until it is connected with the partition section 3192. Both of these settings can achieve the separation and wind guiding effects of the first air guide section 3191.

[0050] Further, see Figure 11 In winter, high-temperature steam flows toward one side of the air outlet 12 and condenses when encountering cold air. A large amount of condensed steam affects the user experience. Therefore, a plurality of air guide ribs 35 are provided on the inner wall of the upper air guide portion 31. The air guide ribs 35 extend from one side of the steam port 318 to one side of the air flow outlet 313. The plurality of air guide ribs 35 are arranged in parallel with the dividing ribs 319 in the X direction, and steam exhaust channels 345 are formed between the dividing ribs 319 and the air guide ribs 35 and between every two adjacent air guide ribs 35. By providing a plurality of steam exhaust channels 345, the steam can be dispersed when discharged from the shell 10 to avoid being ejected in an explosive manner. For example, when the cooking device 100 is used in winter, the ejected high-temperature steam can be prevented from liquefying in the cold air to produce a large amount of cohesive condensed water, which affects the user experience.

[0051] Specifically, see Figure 11In 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 vent 318. Thus, the upper air guide plate 33 overlaps the air outlet portion 343 to direct airflow toward one side of the airflow outlet 313. In this way, the airflow outlet 313 formed by the lower air guide plate 34 itself facilitates the formation of the desired air outlet structure on the lower air guide plate 34. In other embodiments, the upper air guide plate 33 and the lower air guide plate 34 may jointly enclose the airflow outlet 313.

[0052] Furthermore, corresponding to the manner in which the airflow outlet 313 is formed by the air outlet portion 343, when the air guide rib 35 is provided, the air outlet portion 343 has a certain height in the vertical direction, so that the separating rib 319 and / or the air guide rib 35 are provided to extend to the edge of the lower air guide plate 34, that is, the separating rib 319 and / or the air guide rib 35 extend to the air outlet portion 343, so that the second connecting port 315 and the steam port 318 are completely separated, and after the airflow flows through the second connecting port 315 and the steam port 318, each flows to the airflow outlet 313 through the corresponding channel.

[0053] Among them, when the separating rib 319 and / or the wind guide rib 35 are extended to the edge of the lower wind guide plate 34, the separating rib 319 can extend to the edge of the lower wind guide plate 34, or the wind guide rib 35 can extend to the edge of the lower wind guide plate 34, or the separating rib 319 and the wind guide rib 35 can extend to the edge of the lower wind guide plate 34 at the same time.

[0054] Further, see Figure 11 When the wind outlet 313 is formed by the lower wind guide plate 34 itself, the wind outlet portion 343 includes multiple wind outlets 313, and a partition plate 344 is provided between each two adjacent wind outlets 313. An air guide rib 35 and a partition plate 344 are correspondingly provided. In this way, a steam exhaust channel 345 is formed between each two adjacent wind guide ribs 35, and one steam exhaust channel 345 corresponds to one wind outlet 313, so that the steam can be dispersed when discharged from the shell 10 to avoid being ejected in an explosive manner.

[0055] Specifically, when the air guide ribs 35 are set, some of the air guide ribs 35 extend from the steam port 318 to one side of the airflow outlet 313, and one of the air guide ribs 35 is arranged between the steam port 318 and the side wall of the lower air guide plate 34 along the X direction, so that a steam exhaust channel 345 is formed between each adjacent air guide rib 35 extending from the steam port 318 to one side of the airflow outlet 313. The air guide rib 35 arranged between the steam port 318 and the side wall of the lower air guide plate 34 has a blocking effect to prevent steam from overflowing to the edge of the lower air guide plate 34, and also has a wind guiding effect to direct the airflow flowing in from the airflow inlet 311 to flow to one side of the steam port 318.

[0056] See also Figure 11 318 , the steam discharged from the steam port 318 is directed to the airflow outlet 313 as much as possible, the air guide rib 35 located between the side wall of the lower air guide plate 34 and the steam port 318 along the X direction is defined as a first air guide rib, the first air guide rib includes a second air guide section 351 and a third air guide section 352, the second air guide section 351 and the third air guide section 352 are arranged at an angle, and the second air guide section 351 is inclined toward the side away from the steam port 318. In this way, by providing the second air guide section 351 inclined toward the side away from the steam port 318, the distance between the second air guide section 351 and the steam port 318 is increased, which is equivalent to expanding the air intake opening, so as to guide more airflow flowing in from the airflow inlet 311 to flow into the space between the steam port 318 and the second air guide section 351, thereby improving the effect of discharging steam; by providing the third air guide section 352, a steam exhaust channel 345 is formed between the adjacent air guide ribs 35, thereby achieving the effect of discharging steam and airflow.

[0057] Furthermore, according to the setting position of the steam port 318 and the airflow outlet 313, the third air guide section 352 is arc-shaped and bent toward the side wall of the lower air guide plate 34 along the X direction, so that there is sufficient spacing between the third air guide section 352 and the adjacent air guide ribs 35, that is, the airflow outlet 313 corresponding to the steam exhaust channel 345 can have a sufficient width along the X direction to ensure the air outlet effect.

[0058] Understandably, see 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 supporting an object on the side facing away from the lower air guide plate 34, at least one supporting rib 341 is provided on the side of the lower air guide plate 34 facing the upper air guide plate 33. The supporting rib 341 and the upper air guide plate 33 are abutted against each other, that is, the supporting rib 341, the air guide rib 35 and the separating rib 319 cooperate together to support the upper air guide plate 33 and prevent the upper air guide plate 33 from collapsing.

[0059] Specifically, after the support ribs 341, the air guide ribs 35 and the separating ribs 319 are set, the air guide cavity 312 is divided into three parts. Along the X direction, the leftmost side 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 separating rib 319 corresponds to the steam exhaust channel.

[0060] In addition, to achieve compact utilization of the structure, see Figure 4 and Figure 5 The cooking device 100 of this embodiment further includes a water tank 300, which provides moisture to the food during the cooking process. The water tank 300 is arranged in the planar support area 37 of the upper air guide part 31 to fully utilize the avoidance space formed by the upper air guide part 31 to achieve compact installation between components.

[0061] Furthermore, the arched area 36 has an inclined portion, which can be used to install a circuit board 500, such as a circuit board 500 for opening the water tank 300 or controlling the display screen, so as to fully utilize the installation space formed at the arched area 36.

[0062] Among them, see Figure 10 In this embodiment, the upper and lower air guide plates 33 and 34 are installed by interlocking, ensuring not only fixed installation but also a certain overlap area between them, thereby ensuring sealing. Furthermore, a first mounting post 346 is provided on the lower air guide plate 34, and a second mounting post 333 is provided on the upper air guide plate 33. The first and second mounting posts 346 and 333 are connected by bolts, thereby ensuring stable installation of the entire upper air guide structure 30.

[0063] See also Figures 8 to 10 When the first cooling fan 50 and the second cooling fan 60 are set, the first cooling fan 50 is set in a vertical direction, and the second cooling fan 60 is set in the first connecting port 314 in a horizontal direction. In this way, the first cooling fan 50 set in a vertical manner can ensure the air intake volume, and the second cooling fan 60 set in a horizontal direction 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 in the vertical direction, the occupied height in the vertical direction is reduced, thereby realizing the miniaturization of the entire cooking device 100 in the vertical direction and avoiding resistance to the flow of air.

[0064] See also Figure 10When installing the first cooling fan 50, a mounting structure 334 is provided on the inner wall of the upper air guide plate 33. The mounting structure 334 is used to limit the installation of the first cooling fan 50. In this way, when installing the first cooling fan 50, the first cooling fan 50 is pushed into the air guide cavity 312 in the direction of the mounting structure 334. When it contacts the mounting structure 334, the installation position of the first cooling fan 50 is limited.

[0065] In one embodiment, the mounting structure 334 can be a limit block provided on the inner wall of the upper air guide plate 33, thereby abutting against the first cooling fan 50 to achieve the limitation of the first cooling fan 50; specifically, a card slot 335 is provided on the mounting structure 334 of this embodiment, and the first cooling fan 50 is clamped in the card slot 335 to achieve the limitation of the first cooling fan 50, and then it can be installed by bolts and the lower air guide plate 34.

[0066] Further, see Figure 9 The end of the lower air guide plate 34 is provided with a third mounting post 347, which is provided with a first mounting hole 348. The first cooling fan 50 is provided with a second mounting hole 51. The first mounting hole 348 and the second mounting hole 51 are connected by bolts. In this way, by providing the mounting holes, the first cooling fan 50 is mounted on 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 the event of a subsequent failure of the first cooling fan 50.

[0067] See also Figure 9 In order to 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 column 347 are separately arranged to limit the installation of the cooling fan. That is, through the cooperation of the limiting structure 349 and the third mounting column 347, the installation position of the first cooling fan 50 is limited, which is convenient for subsequent locking of the bolts.

[0068] See also Figure 12 , is a schematic structural diagram of the lower air guiding portion 32 of this embodiment. The lower air guiding portion 32 includes a receiving portion 322 and an air guiding 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 guiding portion 323 forms an air guiding channel 321.

[0069] When setting the lower air guide portion 323, in order to adapt to the installation of other components in the entire cooking device 100, the width of the air guide portion 323 gradually decreases from the receiving portion 322 to the side of the second cooling fan 60. On the one hand, the air guide portion 323 with a gradually decreasing width can adapt to the second cooling fan 60 with a smaller width, and the second cooling fan 60 with a smaller width occupies a smaller installation space, thereby achieving compact installation with other components; on the other hand, the width in the direction of the receiving portion 322 is gradually increased, so that the airflow driven by the second cooling fan 60 can be dissipated on the imaging device 40, taking away heat from more areas of the imaging device 40, and achieving better heat dissipation effect.

[0070] Furthermore, when the second cooling fan 60 and the lower air guide portion 323 are connected, the two can be implemented in an overlapping manner, for example, the air outlet 61 of the second cooling fan 60 is set on the end of the air guide portion 323, so that the airflow flowing out of the second cooling fan 60 can flow into the air guide portion 323.

[0071] Understandably, see Figure 8 In order to prevent excessive heat from being radiated toward the imaging device 40 during the cooking process, the lower air guide plate 34 is provided with a frame 349a surrounding the outside of the receiving portion 322. The frame 349a can block the transfer of surrounding heat to the imaging device 40, thereby further achieving a protective effect on the imaging device 40.

[0072] See also Figure 12 and Figure 13 When the imaging device 40 of this embodiment is set, it needs to avoid the microwave inlet. Therefore, the imaging device 40 is set away from the center of the inner pot 20. At the same time, in order to ensure that the imaging device 40 has a larger imaging range and avoid shooting 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 is tilted towards the food, thereby having a wider imaging range 400.

[0073] Among them, see Figure 13 The imaging device 40 includes a mounting plate 41, a camera 42 provided on one side of the mounting plate 41, and a heat dissipation fin 43 provided on the other side of the mounting plate 41. The imaging surface 44 of the imaging device 40 mentioned in this embodiment refers to the shooting surface of the camera 42, and the shooting surface is set at an angle to the horizontal plane.

[0074] In one embodiment, when providing the heat dissipation fins 43, multiple heat dissipation fins 43 may be provided, and the gaps between the heat dissipation fins 43 may be oriented in the direction of the airflow, so that the airflow passing through the gaps between the heat dissipation fins 43 can remove heat. Alternatively, in another embodiment, the heat dissipation fins 43 may be arranged to extend perpendicular to the direction of the airflow, thereby also achieving a heat dissipation effect for the camera 42.

[0075] 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 and the horizontal plane have an angle of 15-25°, so that the camera 42 is set toward the food to ensure the imaging range 400.

[0076] 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., which is not limited here.

[0077] Because the imaging device 40 has an angle relative to the horizontal plane, further, in order to be able to stably install the imaging device 40, the receiving portion 322 has a supporting surface 326 for the imaging device 40, and the supporting surface 326 and the imaging device 40 have the same inclination angle, so as to be able to support the camera 42 of the imaging device 40 to avoid a suspended state. It can be understood that a light hole 327 is provided on the supporting surface 326 to enable the imaging device 40 to achieve an imaging effect.

[0078] It can be understood that by setting the lower air guide part 32 at the bottom of the upper air guide part 31, not only can the imaging device 40 be guided by air, but the lower air guide part 32 has a certain height, which is equivalent to providing a distance between the lower air guide part 32 and the thermal insulation pad 70, so as to further reduce the transfer of heat from the cooking cavity 21 to the air guide cavity 312.

[0079] The above-mentioned cooking device 100 is configured with two air inlets 317 in the X direction on the upper air guide portion 31, wherein one air inlet 317 can supply air to the steam port 318 and the imaging device 40 respectively, and the other air inlet 317 can circulate the air flow after the heat is dissipated from electronic components such as the magnetron 80, thereby achieving multiple air guiding effects; by arranging the first cooling fan 50 in a vertical direction, a larger-sized first cooling fan 50 can be arranged, thereby ensuring the air intake volume of the entire air guide structure 30; by arranging the second cooling fan 60 in a horizontal direction, the height of the entire air guide structure 30 and the second cooling fan 60 in the vertical direction is reduced; by arranging the imaging device 40 at an angle relative to the horizontal plane, the imaging range 400 is ensured, thereby avoiding the occurrence of blind spots in shooting.

[0080] The technical means disclosed in the solutions of the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
