DETAILED DESCRIPTION

[0031] The embodiments of the present application are described in detail below, and the embodiments are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout.

[0032] In the present application, unless otherwise explicitly specified and limited, the terms such as "assembly", "connection", "connection" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected; it can be directly connected, or it can be connected through an intermediate medium; it can be connected inside two elements. The terms "upstream" and "downstream" should be defined in the direction of the air flow path, for example, upstream refers to the position close to the air source or the initial position in the air flow path, and downstream refers to the position close to the final flow direction or the position close to the air flow path. For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0033] The technical scheme of the present application and its beneficial effects will be clearer and more explicit through the further description of the specific embodiments of the present application in combination with the drawings of the specification. The description of the embodiments below by referring to the drawings is exemplary, and is intended to explain the present application, and cannot be understood as a limitation of the present application.

[0034] The preferred embodiment provided by the present application is as follows: Figures 1-5As shown, a camera module includes a heat shield 1, a shooting element 2 arranged in the heat shield 1, and a heat dissipation fan 3. The heat shield 1 includes a first side wall 11, a second side wall 12 opposite to the first side wall 11, an air inlet 13 on the first side wall 11, and an air outlet 14 on the second side wall 12. The heat shield 1 is in the shape of a cuboid. The air inlet 13 and the air outlet 14 are in communication to form a heat dissipation channel 15. The heat dissipation fan 3 is located on one side of the air inlet 13. The heat dissipation fan 3 is inside the heat shield 1, and the shooting element 2 is in the heat dissipation channel 15.

[0035] Specifically, the shooting element 2 includes a horizontal support 21, a cantilever support 22 extending from one end of the horizontal support 21, a circuit board 241 fixed on the cantilever support 22, and a camera 24 electrically connected to the circuit board 241. The horizontal support 21 is fixed on the second side wall 12, and the cantilever support 22 is bent towards the first side wall 11. The camera 24 is arranged in the air outlet 14 and is inclined relative to the first side wall 11. By arranging the camera 24 in the heat dissipation channel 15 and at the position of the air outlet 14, the air discharged by the heat dissipation fan 3 can flow through the camera 24 completely and be discharged from the air outlet 14, so as to carry away the heat around the camera 24. Meanwhile, an air flow barrier is formed around the camera 24, and the heat transferred to the camera 24 through air as a medium is reduced.

[0036] The horizontal bracket 21 is fixed to the second side wall 12, and the cantilever bracket 22 bends towards the first side wall 11. Even when the cantilever bracket 22 bends inward towards the heat insulation cover 1, the distance between the second side wall 12 and the first side wall 11 of the heat insulation cover 1 is significantly reduced. This fully utilizes the internal space of the heat insulation cover 1 and effectively reduces its thickness, thus allowing the camera module to be used with cooking appliances in tight installation gaps. Since the tilt angle of the camera 24 needs to be within a certain range, if the cantilever bracket 22 bends away from the first side wall 11, the cantilever end of the cantilever bracket 22 will be relatively close to or beyond the second side wall 12, and the camera 24 will protrude from the cantilever bracket 22. Simultaneously, the heat insulation cover 1 needs sufficient space for the camera 24 and the cantilever bracket 22 to fine-tune their angles. Therefore, the distance from the first side wall 11 to the end of the camera 24 will inevitably be relatively thick. The cantilever bracket 22 can be made of a plastic material. The purpose of the cantilever bracket 22 is not only to allow the camera 24 to tilt downwards relative to the second sidewall 12, but also to fine-tune the tilt angle of the camera 24. The horizontal bracket 21 and the cantilever bracket 22 are integrally molded structures, with one end of the horizontal bracket 21 extending and bending to form the cantilever bracket 22. Because the cantilever bracket 22 is made of plastic material, it can be bent to adjust the tilt angle of the cantilever bracket 22, thereby adjusting the tilt angle of the camera 24. During testing and adjustment, after the camera module is fixed outside the cooking cavity, the first sidewall 11 is removed. At this time, the tilt angle of the camera 24 can be adjusted in real time without the need for cumbersome disassembly, adjustment, and reinstallation, greatly facilitating product testing, calibration, and after-sales maintenance.

[0037] It should be noted that when a conventional camera is tilted to the outside of the cooking cavity, the following problems may occur:

[0038] ① An axial flow fan is installed on the outside of the camera. The thickness of the camera module is at least the thickness of the axial flow fan plus the length of the camera, so the thickness of the camera module is relatively thick.

[0039] ② By using fans in other locations and additional air ducts to dissipate heat from the camera, it can be thinner at the camera location, but it requires more space. In addition, due to the complexity of the overall structure and the numerous and messy structural parts, the assembly during product manufacturing is cumbersome, which increases the production cost.

[0040] ③ Due to the injection molding demolding process, when the camera is tilted, the mounting base is usually set as an inclined surface with a fixed angle, and the camera is then fixed on the inclined surface. The camera can only be installed or its angle adjusted after the second side wall 12 is removed. This requires reserving space for installation, and the distance between the first side wall 11 and the second side wall 12 is relatively thick.

[0041] ④Camera is inclined to set outside the second side wall 12, similar to the case of ①③, which will also increase the thickness of the heat shield 1.

[0042] In an optional embodiment, the heat dissipation fan 3 is outside the heat shield 1, but the heat dissipation fan 3 needs to be on one side of the air inlet 13. At this time, the air inlet 13 can be on the side wall opposite to the second side wall 12, that is, the side wall where the air inlet 13 is located can be adjacent to the second side wall 12. The position of the air inlet 13 is set on the side wall opposite to or adjacent to the second side wall 12, which can be considered as an equivalent scheme to the scheme of "the air inlet 13 is set on the first side wall 11". The purpose of this embodiment is to illustrate that the air inlet 13 and the air outlet 14 are connected and have a heat dissipation channel 15 for air flow, and the heat dissipation fan 3 can be set in the heat dissipation channel 15 or outside the heat dissipation channel 15 but needs to be on one side of the air inlet 13.

[0043] Further, the cooking cavity is generally in a cuboid structure. Since it is necessary to collect image information in the cooking cavity of the cooking appliance, the camera 24 is set at a higher position on the side of the cooking cavity and is inclined to the bottom of the cooking cavity. The camera 24 can collect more effective image information of the cooking cavity, thereby avoiding the problem of incomplete image information of the cooking cavity. Therefore, the camera module can be directly installed on the cooking appliance, such as an oven, an air fryer, etc., as an independent module by setting the camera module 2 in the heat shield 1. Only the angle of the cantilever bracket 22 needs to be adjusted to synchronize the angle of the camera 24, thereby avoiding complicated installation and adjustment of the camera 24 and saving a lot of assembly time, further improving the production efficiency.

[0044] In this embodiment, the second side wall 12 extends to form two first extension parts 121 on both sides of the air outlet 14 and away from the first side wall 11;

[0045] The two first extending parts 121 are oppositely arranged, and the distance between the two first extending parts 121 is tapered in the direction away from the second side wall 12. Specifically, the second side wall 12 is convexly formed in the direction away from the first side wall 11 at the position of the air outlet 14 to form a three-prism structure, and the end of the camera 24 is located in the internal space of the three-prism. The plane where the air outlet 14 is located is close to the first end of the first extending part 121; the first end is the end of the first extending part 121 away from the second side wall 12, and the second end of the first extending part 121 is the end of the first extending part 121 close to the second side wall 12. Due to the inclination of the two first extending parts 121 towards each other and the tapered distance between the two first extending parts 121 in the direction away from the first side wall, the cross-sectional area of the internal space of the three-prism at the second end is greater than the cross-sectional area at the first end; when the power of the cooling fan 3 is constant, that is, the air intake amount at the air inlet 13 is constant, the air pressure at the first end is greater than the air pressure at the second end. Therefore, after the air passes through the internal space of the three-prism, the air flow rate at the air outlet 14 is increased, so that the air with high flow rate is formed and sprayed out of the air outlet 14 while taking away the heat on the camera 24, further reducing the temperature outside the air outlet 14.

[0046] In the embodiment, the second side wall 12 extends upwards and in the direction away from the first side wall 11 to form a second extending part 122 inclined downward above the air outlet 14. The air outlet 14 is located in the space enclosed by the first extending part 121 and the second extending part 122. Specifically, the embodiment increases the difference between the cross-sectional area at the second end and the cross-sectional area at the first end in the internal space of the three-prism, thereby increasing the difference in pressure between the two cross sections. Further increase the flow rate of air at the air outlet 14.

[0047] In the embodiment, the camera 24 is fixed on the cantilever support 22 by the support support leg 23, and there is a gap between the camera 24 and the cantilever support 22. Specifically, the circuit board 241 in the camera 24 is fixed on the support support leg 23, and the support support leg 23 is fixed on the cantilever support 22; at this time, the support support leg 23 separates the circuit board 241 and the cantilever support 22; there is a gap between the circuit board 241 and the cantilever support 22 for air flow. The air passing through the gap can take away the heat on the circuit board 241. When the cantilever support 22 is a strip structure or a plate structure, the camera 24 and the circuit board 241 are fixed on the cantilever support 22 close to the second side wall 12.

[0048] Further, the camera 24 and the circuit board 241 are integrated into a camera module, that is, the camera 24 is fixed on the circuit board 241 by soldering. After the circuit board 241 is fixed on the cantilever support 22 by the support support leg 23, the camera 24 is indirectly fixed on the cantilever support 22.

[0049] In the embodiment, the circuit board 241 is fixed on the cantilever support 22 near the first side wall 11, and the camera 24 extends from the position near the first side wall 11 to the exhaust port 14. Specifically, the cantilever support 22 is a plate structure and has a through hole in the middle, and the camera 24 is arranged in the through hole. The circuit board 241 on the camera 24 is fixed on the cantilever support 22 near the first side wall 11. At this time, since the camera 24 is recessed from the second side wall 12 to the first side wall 11, the camera 24 is protruded on the cantilever support 22 near the second side wall 12, which can better utilize the space of the cantilever support 22 to the first side wall 11, thereby reducing the distance between the first side wall 11 and the second side wall 12, and further reducing the volume and thickness of the heat shield 1.

[0050] In an alternative embodiment, the cantilever support 22 is a plate structure without a through hole in the middle. The circuit board 241 extends to one side of the cantilever support 22, and the camera 24 is fixed on the circuit board 241. At this time, the camera 24 is located on the aforementioned one side of the cantilever support 22. Without the obstruction of the cantilever support 22, the camera 24 can also achieve the purpose of effectively utilizing the space of the cantilever support 22 to the first side wall 11 and reducing the distance between the first side wall 11 and the second side wall 12, thereby making the heat shield 1 thin and light.

[0051] Of course, the camera 24 and the circuit board 241 can also be electrically connected by wires or flexible wires, in which case the camera 24 needs to be fixed separately. However, the scheme of fixing the camera 24 separately is not conducive to reducing the volume or thickness of the heat shield 1.

[0052] As shown in Figures 1-11 The utility model also provides a kind of cooking utensil: including camera module, shell 4, liner 5, lining plate 6, heat shield support 7;Shell 4 and liner 5 between there is first installation space 41;Liner 5 side wall upper portion and the place near liner 5 top wall has first light transmission hole 51;Camera 24 in camera module is located in the side of first light transmission hole 51;Camera 24 passes through first light transmission hole 51 and gathers image information in liner 5.

[0053] The camera module is fixed on the lower surface of the backing plate 6 and located in the first mounting space 41; the heat insulation support 7 is fixed on the upper surface of the backing plate 6 and located above the camera module; the main control board is installed in the heat insulation support 7; since the electrical components on the main control board are relatively sensitive to temperature, the main control board needs an independent heat insulation structure; the heat insulation support 7 is on the backing plate 6, and the backing plate 6 can block part of the heat from the cooking cavity of the inner container 5; the main control board further blocks the heat from the cooking cavity of the inner container 5 through the heat insulation support 7.

[0054] By fixing the heat insulation support 7 and the heat insulation cover 1 on the upper and lower sides of the backing plate 6, and locating the heat insulation cover 1 below the heat insulation support 7, the heat insulation cover 1 also blocks part of the heat transferred from the inner container 5, further reducing the heat transferred from the bottom of the backing plate 6 to the heat insulation support 7, and reducing the influence of the high temperature of the inner container 5 on the main control board. Therefore, the embodiment achieves the purpose of installing the camera module in a small space, while also effectively reducing the heat transferred from the inner container 5 to the main control board.

[0055] The air inlet 13 on the heat insulation cover 1 is in communication with the outside through the through hole on the outer shell 4; the cooling fan 3 obtains air with lower temperature from the outside through the air inlet 13 and the through hole on the outer shell 4.

[0056] It should be noted that the current cooking utensils, such as ovens, will have many structures on the backing plate 6, such as heat dissipation structures, water tanks, steam generators, waterway pipelines, display panel flip drive structures, door body push-out structures, and various motors. In addition, the camera module also needs to ensure the quality of the image information collected by the camera 24, so that the installation position of the camera module is limited to the middle position of the few sides near the upper part of the inner container 5, thereby increasing the limitation of the installation position of the camera module and having a high requirement on the volume or thickness of the camera module.

[0057] In the embodiment, the bottom surface of the heat insulation support 7 is provided with a heat insulation support foot 71; the heat insulation support foot 71 is fixed on the upper surface of the backing plate 6. The heat insulation support foot 71 separates the bottom surface of the heat insulation support 7 from the backing plate 6, so that there is an air flow gap between the bottom surface of the heat insulation support 7 and the backing plate 6. The thermal conductivity of air is lower than that of metal / engineering plastic, and the aforementioned gap can act as an effective heat insulation layer, thereby greatly reducing the heat transferred from the backing plate 6 to the heat insulation support 7.

[0058] In addition, since there is a gap between the bottom surface of the heat insulation support 7 and the backing plate 6, the aforementioned gap provides a space for the heat insulation cover 1 to fix the fasteners, thereby avoiding the protrusion of the fasteners affecting the installation and fixation of the heat insulation support 7, and further improving the operability of fixing the camera module and reducing the disassembly difficulty of the user / assembly personnel.

[0059] The top surface of the heat shield 1 is provided with mounting holes 16, and fasteners are respectively connected with the mounting holes 16 after passing through the bottom surface of the heat shield support 7 and the backing plate 6. The fasteners are screws. Specifically, the bottom surface of the heat shield support 7 has a hole for mounting a screw, and the positions of the mounting holes 16 on the top surface of the heat shield 1 are adapted to the positions of the aforementioned holes. When assembling the heat shield support 7 and the heat shield 1, the heat shield support 7 is first fixed on the upper surface of the backing plate 6, at this time, the heat shield support 7 is fixed by using screws passing through the heat shield support feet 71 to be fixed on the backing plate 6, or by using screws passing through the bottom surface of the heat shield support 7 to be fixed on the backing plate 6; then the heat shield 1 is placed on the lower surface of the backing plate 6, and the screws passing through the bottom surface of the heat shield support 7 are screwed with the mounting holes 16 after passing through the backing plate 6.

[0060] In a preferred embodiment, the heat shield support feet 71 have holes for mounting screws inside, and the positions of the mounting holes 16 on the top surface of the heat shield 1 are adapted to the positions of the heat shield support feet 71. When assembling the heat shield support 7 and the heat shield 1, the heat shield support 7 is first fixed on the upper surface of the backing plate 6, at this time, the heat shield support 7 is fixed by using screws passing through part of the heat shield support feet 71 to be fixed on the backing plate 6; then the heat shield 1 is placed on the lower surface of the backing plate 6 and at a position matched with the positions of the heat shield support feet 71, and then the screws are connected and fixed with the mounting holes 16 on the top surface of the heat shield 1 by passing through the through holes in another part of the heat shield support feet 71 and passing through the backing plate 6.

[0061] In an alternative embodiment, the fasteners described above can be replaced by other clamping or inserting members, and the core assembly process is that the fasteners are connected and fixed with the heat shield 1 after passing through the bottom surface of the heat shield support 7 and the backing plate 6.

[0062] The fasteners described above can be screws, bolts, clamps, inserts, dowel connections and other conventional fastening methods.

[0063] In the embodiment, the shape of the side wall of the inner container 5 matches the second side wall 12; since the first extension 121 protrudes from the second side wall 12, the inner container 5 also needs to have a structure protruding inward from the side wall of the inner container 5 to match the first extension 121, so as to avoid interference with the first extension 121. The side wall of the inner container 5 protrudes inwardly to form two first shielding portions 511 and a second shielding portion 512, and the first extension 121 is located in the space enclosed by the first shielding portion 511 and the second shielding portion 512. Each first shielding portion 511 is provided with one side corresponding to one first extension 121. The second shielding portion 512 is provided with one side corresponding to the second extension 122. The second side wall 12 and the side wall of the inner container 5 have a gap therebetween. The air discharged from the air outlet 14 is discharged to the aforementioned gap, and further cools and lowers the temperature of the second side wall 12 and the inner container 5 on both sides of the aforementioned gap, thereby lowering the temperature of the environment around the camera 24. In addition, under the action of the heat dissipation fan 3, there is constantly flowing air in the aforementioned gap; since the thermal conductivity of air is low, the flowing air not only takes away the heat in the gap, but also forms an air insulation layer, thereby further isolating the heat transferred from the inner container 5.

[0064] In the embodiment, the first light transmission hole 51 protrudes towards the inside of the inner container 5; the first light transmission hole 51 is obliquely arranged towards the bottom of the inner container 5. The camera 24 is located outside the first light transmission hole 51, and the camera 24 collects image information in the inner container 5 through the first light transmission hole 51. Since the first extension 121 protrudes from the second side wall 12, the inner container 5 also needs to have a structure protruding inward from the side wall of the inner container 5 to match the first extension 121, so as to avoid interference with the first extension 121. The camera 24 is relatively obliquely downward in the heat shield 1, and the camera 24 needs to be aligned with the first light transmission hole 51, so the first light transmission hole 51 needs to be obliquely arranged towards the bottom of the inner container 5.

[0065] In the preferred embodiment, the camera 24 and the first light transmission hole 51 are further provided with a heat insulation glass 52; the heat insulation glass 52 is fixed on the side wall of the inner container 5. The air outlet 14 and the heat insulation glass 52 have a gap; the camera 24 and the heat insulation glass 52 have a gap. The air discharged from the air outlet 14 is first discharged to the heat insulation glass 52, and then flows to other positions in the gap between the second side wall 12 and the side wall of the inner container 5. The purpose of such arrangement is to enable the air discharged from the air outlet 14 to cool the camera 24, the heat insulation glass 52 and the side wall of the inner container 5 through the heat dissipation fan 3; and to achieve the effect that only one heat dissipation fan 3 can cool multiple structural members or multiple positions.

[0066] In the embodiment, the top heating tube 54 is further included; the second shielding part 512 is arranged obliquely relative to the side wall of the inner container 5 above the first light-transmitting hole 51; the second shielding part 512 is arranged obliquely towards the bottom surface of the inner container 5; the second shielding part 512 can shield part of the stray light emitted by the illuminating lamp 82 on the top wall of the inner container 5, reduce the stray light directed to the first light-transmitting hole 51, and improve the imaging effect of the camera 24. At least part of the second shielding part 512 is below the top heating tube 54; the obliquely arranged second shielding part 512 can reflect part of the heat radiation of the top heating tube 54, reduce the heat radiation of the top heating tube 54 directly received by the first light-transmitting hole 51, reduce the temperature or temperature rising rate at the position of the first light-transmitting hole 51, thereby reducing the heat transferred to the camera 24, and improving the stability of the operation of the camera 24 and the service life of the camera 24.

[0067] Specifically, part of the second shielding part 512 is below the side of the top heating tube 54; the top heating tube 54 is on the top wall of the inner container 5, and the second shielding part 512 is on the side wall of the inner container 5; the second shielding part 512 only needs to be below the side of the top heating tube 54 to achieve the effect of reflecting the heat radiation of the top heating tube 54.

[0068] In some optional embodiments, the first shielding part 511 close to the rear wall of the inner container 5 is arranged obliquely. When the rear wall of the inner container 5 is also provided with a rear heating tube, the obliquely arranged first shielding part 511 can also have the effect of reflecting the heat radiation of the rear heating tube and reducing the heat radiation of the rear heating tube directly received by the first light-transmitting hole 51.

[0069] In the embodiment, the illumination assembly 8 is further included; the illumination assembly 8 includes the second light-transmitting hole 53, the spotlight cover support 81, and the illuminating lamp 82.

[0070] The second light-transmitting hole 53 is arranged at a position close to the center of the top wall of the inner container 5; the illuminating lamp 82 is mounted in the spotlight cover support 81; the illuminating lamp 82 at the central position of the top wall of the inner container 5 can make the light and shadow effect of the food and tableware in the inner container 5 better, and make the imaging effect of the food more stereoscopic.

[0071] The spotlight cover support 81 is protruded on the upper surface of the inner container 5 and / or the upper surface of the lining plate 6 and above the second light-transmitting hole 53; the illuminating lamp 82 is avoided to protrude on the top wall of the inner container 5, thereby avoiding the light of the illuminating lamp 82 directly irradiating the camera 24, and further improving the imaging effect of the camera 24. The spotlight cover support 81 can be protruded on the upper surface of the inner container 5 or the lining plate 6, or can be mounted on the upper surface of the inner container 5 and protrude on the lining plate 6; the spotlight cover support 81 is arranged on the side of the illuminating lamp 82, and is used for mounting the illuminating lamp 82, reflecting the light of the illuminating lamp 82, and avoiding the illuminating lamp 82 protruding to the inner side of the inner container 5.

[0072] The top heating tube 54 has a heating tube avoiding portion 541 arranged at the side of the second light-transmitting hole 53; after the heating tube avoiding portion 541 avoids the second light-transmitting hole 53, the light hitting the top heating tube 54 will not be projected to the baking tray / food material below the second light-transmitting hole 53, avoiding the shadow of the top heating tube 54 on the food material to affect the imaging effect, and avoiding the problem of misjudgment of the food material state by the main control board due to the shadow on the food material.

[0073] In the embodiment, the inner container 5 has a second installation space of a slide rail support 55 formed by sinking the side wall of the inner container 5 towards the outer shell 4; the slide rail support 55 has an avoiding structure at the first light-transmitting hole 51. The slide rail support 55 is a metal grid structure. The second installation space has a clamping piece for fixing the slide rail support 55. Of course, the fixing of the slide rail support 55 can also be achieved by screws and other fasteners. The metal property of the slide rail support 55 makes it have a certain elasticity, so that after the user squeezes the slide rail support 55, the slide rail support 55 can be clamped to the clamping piece. The slide rail support 55 has a baking tray guide rail, and the baking tray can slide on the baking tray guide rail to realize disassembly and assembly. The slide rail support 55 has a support avoiding portion 551 at the position close to the first light-transmitting hole 51. The support avoiding portion 551 is arranged at the side of the first light-transmitting hole 51, and is used for avoiding shielding the first light-transmitting hole 51 and connecting two end portions of the slide rail support 55 to enhance the structural strength of the slide rail support 55.
