Detailed Implementation

[0032] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0033] Hereinafter, with reference to the accompanying drawings, a cooking apparatus 100 according to an embodiment of the present application will be described.

[0034] As shown in Figures 1-7, the cooking device 100 according to an embodiment of this application includes: a housing 1, a cooking body 2, a plurality of lighting components 3, and a camera 4. The cooking body 2 is disposed inside the housing 1, and a heat dissipation duct 11 is provided between the cooking body 2 and the housing 1. At least a portion of the heat dissipation duct 11 is located at the top of the cooking body 2, and the cooking body 2 defines a cooking cavity 21. The camera 4 is disposed on the top wall 22 of the cooking body 2 and is at least partially located within the heat dissipation duct 11. The camera 4 is adapted to capture images of the cooking cavity 21. The plurality of lighting components 3 are disposed on the top wall 22 of the cooking body 2 and are respectively located on both sides of the camera 4. At least a portion of the lighting components 3 is located within the heat dissipation duct 11 and is adapted to irradiate light into the cooking cavity 21.

[0035] This improves the lighting effect of the lighting component 3, makes the shooting angle of the camera component 4 wider, prevents glare, and helps improve the imaging effect. In addition, the cooling airflow of the heat dissipation duct 11 can also cool the lighting component 3 and the camera component 4, improving the working reliability of the lighting component 3 and the camera component 4.

[0036] First, as shown in Figures 1-5, the cooking device 100 includes a housing 1 and a cooking body 2. An installation space is formed within the housing 1, and the cooking body 2 is installed within the installation space of the housing 1. A heat dissipation duct 11 is provided between the cooking body 2 and the housing 1, with at least a portion of the heat dissipation duct 11 located at the top of the cooking body 2. A cooking cavity 21 is defined within the cooking body 2. When the temperature inside the cooking cavity 21 rises, a cooling airflow can circulate within the heat dissipation duct 11 to dissipate heat from the cooking body 2, thereby preventing temperature diffusion within the cooking cavity 21 and thus preventing damage to the cooking device 100 due to high temperatures.

[0037] The cooking device 100 also includes a lighting component 3 and a camera component 4. The lighting component 3 is disposed on the top wall 22 of the cooking body 2, with at least a portion located within the heat dissipation duct 11, allowing the cooling airflow to contact the lighting component 3 for cooling. The lighting component 3 is used to illuminate the cooking cavity 21 to provide high brightness within the cooking cavity 21. Simultaneously, the camera component 4 can be disposed on the top wall 22 of the cooking body 2, with at least a portion located within the heat dissipation duct 11, allowing the cooling airflow to contact the camera component 4 for cooling. The camera component 4 can be a camera, video camera, etc., and is used to capture images of the cooking cavity 21 to obtain image information within the cooking cavity 21.

[0038] Furthermore, multiple lighting components 3 can be provided, with each lighting component 3 positioned on one side of the camera 4 to reduce blind spots. For example, two lighting components 3 can be provided, with each lighting component 3 positioned on one side of the camera 4 along the length of the mounting inclined surface 221 (refer to the left-right direction shown in Figure 5).

[0039] Understandably, by placing the camera 4 on the top wall 22 of the cooking body 2, the shooting angle of the camera 4 can be widened. By placing the lighting components 3 on the top wall 22 of the cooking body 2, and having multiple lighting components 3 located on both sides of the camera 4, the lighting effect of the lighting components 3 can be improved, and direct illumination of the camera 4 by the lighting components 3 can be avoided, thus preventing glare and improving the imaging effect. In addition, the cooling airflow flowing through the top wall 22 of the cooking body 2 can also cool the lighting components 3 and the camera 4, protecting them and thus improving the operational reliability of the lighting components 3 and the camera 4.

[0040] According to the embodiments of the present application, the cooking device 100, by setting the lighting component 3 and the camera 4 on the top wall 22 of the cooking body 2, and setting multiple lighting components 3 respectively on both sides of the camera 4, can improve the lighting effect of the lighting component 3, make the shooting angle of the camera 4 wider, prevent glare, improve the imaging effect, and the cooling airflow of the heat dissipation duct 11 can also cool the lighting component 3 and the camera 4, improving the working reliability of the lighting component 3 and the camera 4.

[0041] In some embodiments of this application, as shown in Figures 1-4, a downward-sloping and outward-inclined mounting surface 221 can be provided on one side of the top wall 22. The lighting component 3 and the camera component 4 are respectively disposed on the mounting surface 221, so that the lighting component 3 can illuminate the cooking cavity 21 at an angle downward, thereby increasing the illumination range, and the camera component 4 can capture images of the cooking cavity 21 at an angle downward, thereby increasing the shooting range of the camera component 4. For example, the mounting surface 221 can be disposed on the front side of the top wall 22. This can improve the imaging effect of the camera component 4.

[0042] In some embodiments of this application, as shown in Figures 3 and 5, the camera 4 is located at the central axis L of the mounting slope 221, and multiple lighting components 3 are symmetrically arranged about the central axis L. This arrangement allows for more uniform light distribution on both sides of the camera 4, thus improving imaging performance.

[0043] In some embodiments of this application, the top wall 22 is provided with a first through hole 222, and the lighting assembly 3 includes a light source 31 and a light diffuser 32. The light source 31 is located on the outside of the cooking cavity 21 and is provided corresponding to the first through hole 222. The light diffuser 32 is located on the top wall 22 to disperse the light emitted by the light source 31.

[0044] For example, referring to Figures 2 and 5, a first through hole 222 can be provided in the top wall 22, penetrating the top wall 22 along its thickness direction. The lighting assembly 3 includes a light source 31 and a light diffuser 32. The light source 31 can be a light-emitting element such as an LED. The light source 31 is located on the outside of the cooking cavity 21 and inside the heat dissipation duct 11. The light source 31 is correspondingly arranged with the first through hole 222 so that the light source 31 can irradiate light into the cooking cavity 21 through the first through hole 222. The light diffuser 32 can be made of a light-diffusing material such as frosted glass. The light diffuser 32 is provided in the top wall 22 and is used to close the first through hole 222. The light source 31 can directly irradiate the light diffuser 32 so that the light diffuser 32 can disperse the light irradiated by the light source 31, thereby allowing the light to be evenly irradiated into the cooking cavity 21.

[0045] The above settings can improve the lighting effect of the lighting component 3, improve the imaging quality, and better dissipate heat from the light source 31, which is conducive to improving the working stability of the light source 31.

[0046] In some embodiments of this application, as shown in Figures 2 and 4, the cooking device 100 of this application further includes a metal fastener 5. The metal fastener 5 is used to install the light-diffusing element 32 to the inner side of the top wall 22, so that the light-diffusing element 32 is installed in the cooking cavity 21. The metal fastener 5 is provided with a light-transmitting hole 53, which is used to avoid the light-diffusing element 32, so that the light irradiated on the light-diffusing element 32 can pass through the light-diffusing element 32 and irradiate into the cooking cavity 21. Through the above arrangement, the light-diffusing element 32 can better guide the light into the cooking cavity 21, which is beneficial to improve the light utilization rate and reduce the power of the light source 31.

[0047] In some embodiments of this application, the metal fastener 5 is formed with a mounting groove 54 for accommodating the light-diffusing element 32, and the bottom wall of the mounting groove 54 is provided with a light-transmitting hole 53. For example, referring to Figures 2 and 6, the metal fastener 5 can be configured to form a mounting groove 54, which is matched with the light-diffusing element 32, so that the light-diffusing element 32 can be accommodated in the mounting groove 54, and the inner peripheral wall of the mounting groove 54 can limit the light-diffusing element 32. The opening of the mounting groove 54 is opposite to the top wall 22, and the bottom wall of the mounting groove 54 is provided with a light-transmitting hole 53. The light-transmitting hole 53 can be aligned with the first through hole 222, so that the light irradiated by the first through hole 222 onto the light-diffusing element 32 can directly irradiate the cooking cavity 21 through the light-transmitting hole 53. The above configuration helps to improve the installation stability of the light-diffusing element 32.

[0048] In some embodiments of this application, the metal fastener 5 can be detachable from the top wall 22. With the above-mentioned arrangement, when the light-diffusing element 32 ages or is damaged, the metal fastener 5 can be disassembled and reassembled to facilitate the replacement of the light-diffusing element 32, thereby improving the practicality of the cooking equipment 100.

[0049] In some embodiments of this application, as shown in FIG6, the metal fastener 5 includes a main body 51 and a mounting part 52. A mounting groove 54 is formed within the main body 51. Two mounting parts 52 are respectively located on both sides of the main body 51 along the horizontal direction. The mounting parts 52 are used to fit snugly onto the top wall 22 to connect the metal fastener 5 to the top wall 22. Exemplarily, as shown in FIG4, 6, and 7, mounting holes 521 can be provided on the mounting parts 52, and mounting through holes 224 can be provided on the top wall 22. Fasteners 7 can sequentially pass through the mounting holes 521 and 224 and be connected to a nut to fix the metal fastener 5 to the top wall 22. Through the above configuration, the installation stability of the metal fastener 5 can be improved, the installation stability of the light-diffusing component 32 can be ensured, and the reliability of the cooking equipment 100 can be improved.

[0050] In some embodiments of this application, as shown in FIG2, the lighting assembly 3 further includes a sealing member 6. The sealing member 6 may be made of an elastic heat-resistant material such as rubber. At least a portion of the sealing member 6 is circumferentially sandwiched between the light-diffusing member 32 and the top wall 22, and the sealing member 6 is used to seal the gap between the light-diffusing member 32 and the top wall 22 to prevent high-temperature gas in the cooking cavity 21 from flowing into the heat dissipation duct 11 through the first through hole 222. Exemplarily, the sealing member 6 can be constructed as an annular shape and sandwiched between the light-diffusing member 32 and the top wall 22. This can improve the reliability of the cooking device 100.

[0051] In some embodiments of this application, the sealing element 6 includes a sealing body 61 and a sealing flange 62 connected together. The sealing body 61 is sleeved on the outside of the light-diffusing element 32. There are two sealing flanges 62, which extend to both sides of the light-diffusing element 32 along the thickness direction and are matched with the light-diffusing element 32 for limiting.

[0052] For example, referring to Figure 2, the sealing element 6 includes a sealing body 61 and sealing flanges 62. The sealing body 61 is annular and is used to sleeve the outer side of the light-diffusing element 32 to shield the outer peripheral wall of the light-diffusing element 32. There are two sealing flanges 62, which are respectively connected to opposite ends of the sealing body 61 along the axial direction. The two sealing flanges 62 extend to both sides of the light-diffusing element 32 along the thickness direction and are matched with the light-diffusing element 32 to fix the sealing element 6 on the light-diffusing element 32.

[0053] Understandably, the sealing element 6 can separate the light-diffusing element 32 from the metal fixing element 5 and the top wall 22 to prevent the light-diffusing element 32 from being damaged by impact, and can also ensure the sealing performance of the first through hole 222.

[0054] In some embodiments of this application, as shown in FIG7, the first through hole 222 may include a main light hole 2221 and an expansion hole 2222, wherein there are multiple expansion holes 2222 surrounding the main light hole 2221. Preferably, the main light hole 2221 may be constructed as a circle, and the expansion holes 2222 as arc-shaped, to maximize the use of the space of the top wall 22. Through the above configuration, the size of a single opening can be reduced, the structural strength of the top wall 22 can be improved, microwave leakage can be prevented, and the reliability of the cooking device 100 can be improved.

[0055] In some embodiments of this application, the maximum diameter of both the main lamp hole 2221 and the expansion hole 2222 can be less than or equal to 16 mm. Specifically, the maximum diameter of the main lamp hole 2221 can be 8 mm, 10 mm, 12 mm, 14 mm, etc., and the maximum diameter of the expansion hole 2222 can be 8 mm, 10 mm, 12 mm, 14 mm, etc., and this application does not impose any limitations on this. Through the above settings, the diameters of both the expansion hole 2222 and the main lamp hole 2221 can be relatively small, which is beneficial for preventing microwave leakage.

[0056] In some embodiments of this application, the distance between the main lamp hole 2221 and the expansion hole 2222 is not less than 3mm. For example, the distance between the main lamp hole 2221 and the expansion hole 2222 can be set to 3.5mm, 4mm, 4.5mm, etc. Through the above settings, the processing difficulty of the first through hole 222 can be reduced, and the structural stability of the top wall 22 can be improved.

[0057] In some embodiments of this application, a second through hole 223 may be provided on the top wall 22, and the camera 4 may be correspondingly arranged with the second through hole 223 so that the camera 4 can capture images of the cooking cavity 21 through the second through hole 223. The axial direction of the first through hole 222 and the axial direction of the second through hole 223 are kept parallel so that the camera orientation of the camera 4 can be set parallel to the orientation of the light source 31. This can prevent glare and improve image quality.
