With the pursuit of high-quality life by users, microwave cooking devices with intelligent cooking functions bring more convenience to users' cooking operations. Based on cameras, intelligent cooking functions can perform various auxiliary cooking operations such as ingredient recognition and cooking process recognition. Since cameras are not resistant to high temperatures, they are generally arranged outside the inner cavity and shoot through a view window. To prevent microwave leakage problems, the view window uses a metal mesh, and the aperture that can be opened is relatively small. When the camera shoots the cooking cavity through the view window, due to the small aperture and mesh shape of the opening, the view window will block the lens, so that the camera cannot collect panoramic image data of the cooking cavity. Summary of the Utility Model

[0009] The included angle between the axis of the camera and the vertical plane of the shielding net is less than 5°.

[0010] In one embodiment, the aperture diameter of the mesh holes is not greater than 4 mm, and the hole edge distance is not less than 1.5 mm.

[0011] In one embodiment, the moving path has a plurality of photographing positions arranged at intervals. The camera moves along the moving path and sequentially takes pictures at the plurality of photographing positions. The interval distance between two adjacent photographing positions is S, and the aperture diameter of the mesh holes is D. S is a non-integer multiple of D and S > 0; and / or,

[0012] The length of the moving path is not less than 50 mm.

[0017] Advantages of the present utility model:

[0018] The cooking device provided by the present utility model includes a processor and a camera movably connected to the inner container. The camera and the cooking cavity are located on both sides of a shielding net. The lens diameter of the camera is larger than the aperture of the mesh hole. The camera can take pictures of the cooking cavity to form image data. The processor can output a display image according to the image data captured through the shielding net at different positions on the moving path. The cooking device provides auxiliary cooking operations through the output display image, and the display image provides image information to the user, enabling the user to directly identify the type of ingredients, judge the ripeness of the ingredients, judge the cooking process, etc., increasing the intelligence of the cooking device and enhancing the user experience.

[0023] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the sake of description, only parts related to the present utility model are shown in the drawings, rather than all the structures.

[0027] Such as Figure 1 And Figure 2As shown in the figure, this embodiment provides a cooking device. The cooking device includes an inner container 1, the inner container 1 has a cooking cavity 11, and the microwave in the cooking cavity 11 is used to heat and cook food. The inner container 1 is provided with a shielding net 2 facing the cooking cavity 11. The shielding net 2 can shield the microwave in the cooking cavity 11, and the shielding net 2 has a plurality of mesh holes 21. The cooking device further includes a processor and a camera 31 movably connected to the inner container 1. The camera 31 and the cooking cavity 11 are located on both sides of the shielding net 2. The lens diameter of the camera 31 is larger than the aperture diameter of the mesh hole 21, and the camera 31 can take pictures of the cooking cavity 11 to form image data. The processor can output a display image according to the image data taken by the camera 31 through the shielding net 2 at different positions on the moving path. The cooking device provides an auxiliary cooking operation through the output display image. The display image provides image information to the user, enabling the user to directly identify the type of ingredients, judge the maturity of the ingredients, judge the cooking process, etc., increasing the intelligence of the cooking device and improving the user experience. Since the lens diameter of the camera 31 is larger than the aperture diameter of the mesh hole 21, the entity between adjacent mesh holes 21 will block the camera 31, making the image data taken by the camera 31 at one time have an occlusion area. The camera 31 can take multiple pictures at different positions on the moving path to form multiple groups of image data. Since the shooting position of the camera 31 relative to the cooking cavity 11 is different, the occlusion areas of the image data obtained each time are also different. The processor can remove the occlusion areas of each group of image data and combine the multiple groups of image data with the occlusion areas removed to form at least one group of display images without occlusion areas, thereby realizing panoramic image acquisition and image information display of the cooking cavity 11. While effectively shielding the microwave and preventing microwave diffusion, the cooking device can eliminate the occlusion effect of the shielding net 2 on the camera 31 and improve the comprehensiveness of the displayed image information.

[0028] The principle of the cooking device to achieve the above-mentioned auxiliary cooking operation through image data, and the specific process of the processor removing occlusion, synthesizing into a panoramic image and outputting a display image through an algorithm can be set with reference to the prior art, and will not be elaborated in this embodiment.

[0029] The inner container 1 includes a top plate and a plurality of side plates that enclose to form the cooking cavity 11. Since the cooked food is generally located in the middle of the cooking cavity 11, in order to make the shootable area of the camera 31 completely cover the cooked food, the shielding net 2 is arranged on the top plate and the shielding net 2 is located in the middle of the top plate, or the shielding net 2 is arranged on any one of the plurality of side plates and the shielding net 2 is located in the middle of the side plate.

[0030] In one embodiment, along the direction perpendicular to the shielding net 2, the distance between the camera 31 and the shielding net 2 is not greater than 20 mm. Since an increase in the distance between the camera 31 and the shielding net 2 will affect the coverage area of a single shot, it is appropriate that the distance between the camera 31 and the shielding net 2 is not greater than 20 mm.

[0031] Specifically, in one embodiment, the shielding net 2 is disposed at the top of the inner container 1, and the camera 31 is disposed above the top plate. As Figure 1 and Figure 2 shown, that is, the camera 31 is located above the inner container 1, and captures image data from top to bottom through the shielding net 2 on the top plate. Placing the camera 31 above the inner container 1, on the one hand, the captured image data is more in line with the viewing angle of the user looking down into the cooking cavity 11 from top to bottom, and on the other hand, it also reduces the space occupied by the camera 31 in the width or thickness direction of the inner container 1.

[0032] The included angle between the axis of the camera 31 and the vertical plane of the shielding net 2 is less than 5°. That is, the axis of the camera 31 is perpendicular or approximately perpendicular to the shielding net 2, reducing the distance between the camera 31 and the shielding net 2. The camera 31 can be as close as possible to the shielding net 2. On the one hand, it avoids the influence of the network cable on the focusing of the camera 31, and on the other hand, it reduces the distance between the camera 31 and the cooked food in the cooking cavity 11, improving the clarity of the captured image.

[0033] The commonly used microwave frequency of the microwave integrated machine is 2450 HZ, and the wavelength is 12.22 cm. Therefore, the aperture of the mesh hole 21 is not greater than 4 mm, and the hole edge distance is not less than 1.5 mm, which can better shield and block the microwave of this frequency.

[0034] The moving path has multiple shooting positions arranged at intervals. The camera 31 moves along the moving path and shoots at multiple shooting positions in sequence. The interval distance between two adjacent shooting positions is S, and the aperture of the mesh hole 21 is D. S is a non-integer multiple of D and S>0, which can ensure that in the multiple sets of image data formed by multiple shootings, the positions of the occlusion areas on the image data are different. Only in this way can the multiple sets of image data be stitched by removing the occlusion to form a display image without occlusion areas.

[0035] The length of the moving path is not less than 50 mm, and can be specifically selected and set according to the size of the inner container 1. Since the lens diameter of the camera 31 is generally greater than 10 mm, this can ensure that multiple shootings can be performed on the moving path, providing more choices of image data for the synthesized display image.

[0036] There are various ways to extend the moving path. The moving path can be a straight extension path, or the moving path can be a combination of a partial curve extension path and a partial straight extension path. Moreover, the curve path can be an arc curve or any irregular curve, and this embodiment does not make specific limitations.

[0037] The camera 31 can move intermittently along the moving path, or the camera 31 can move continuously along the moving path, so that the camera 31 can realize the following two image data collection methods. In the first image data collection method, the driving member 32 moves continuously from one end point of the moving path to the other end point. During the continuous movement, the camera 31 takes a picture every preset time. The preset time can be 0.1 seconds, 0.2 seconds, or other time intervals. This embodiment does not impose specific restrictions, thereby realizing multi-point mobile shooting; in the second collection method, the camera 31 will stop and shoot at a preset plurality of shooting positions during the movement from one end point of the moving path to the other end point. The preset shooting position is obtained by dividing the moving path into multiple sections. Each interval of the equally divided moving path has a preset shooting position, thereby realizing intermittent moving shooting of the camera 31. The above two image data collection methods can be selected and applied according to the algorithm requirements.

[0038] In order to realize the movement of the camera 31, the cooking device further includes a driving member 32. The driving member 32 can drive the camera 31 to move continuously along the moving path, or the driving member 32 can drive the camera 31 to move intermittently along the moving path. Driven by the driving member 32, the camera 31 moves continuously from one end point to the other end point of the moving path, or moves intermittently during the movement from one end point to the other end point of the moving path and stops to shoot.

[0039] In order to ensure the accuracy of the moving path, the cooking device also includes a guide rail 33, the length of which extends along the moving path to form the moving path of the camera 31. The camera 31 is movably connected to the guide rail 33, and the driving member 32 is transmission-connected to the camera 31 to enable the camera 31 to move along the moving path. The guide rail 33 has a plurality of shooting positions, and the camera 31 is movably arranged on the guide rail 33. The output end of the driving member 32 is connected to the camera 31, and the driving member 32 drives the camera 31 to reciprocate along the guide rail 33, and the camera 31 passes through the plurality of shooting positions in sequence or moves intermittently between the plurality of shooting positions. Figure 1 As shown, the camera 31 is located at the initial point of the guide rail 33; under the drive of the driving member 32, as shown in FIG. Figure 2 As shown, the camera 31 moves to the middle of the moving path along the guide rail 33. In the figure, the guide rail 33 extends in a straight line.

[0040] Specifically, the driving member 32 is a motor. The cooking device further includes a gear (not shown in the figure). The output end of the motor is connected to the gear and the motor is mounted on the camera 31. The motor drives the gear to rotate. The guide rail 33 is provided with a rack. The gear is connected to the camera 31 and meshes with the rack. As the gear meshes and rotates on the rack, the gear moves along the guide rail 33. By utilizing the characteristic of the gear and the rack meshing tooth by tooth, the camera 31 is intermittently moved on the moving path. By using the forward rotation and reverse rotation of the gear, the camera 31 reciprocates on the moving path. Using the motor as the power source, the control method is relatively simple. Moreover, the setting method of the motor following the camera 31 simplifies the structure.

[0041] The guide rail 33 serves as both a guiding member and a supporting member for the camera 31. The guide rail 33 has an inverted U-shaped frame structure, so that there is a certain gap between the rack and the inner container 1 to accommodate the camera 31. And each end of the U-shaped frame structure is provided with an extended mounting portion to connect to the inner container 1, realizing the detachable mounting of the guide rail 33 on the inner container 1.

[0042] In order to limit the stroke of the camera 31, at least one end of the guide rail 33 has a limiting portion 331. The limiting portion 331 is used to abut and limit the camera 31, preventing the camera 31 from moving beyond the range of the shielding net 2 due to overtravel, or the camera 31 moving out of the guide rail 33 due to overtravel.

[0043] As Figure 1 shown, stop steps are provided at both ends of the guide rail 33 as the limiting portion 331. When the camera 31 abuts against the stop steps, the stop steps prevent the camera 31 from continuing to move, thereby realizing the limitation of the camera 31.

[0044] In one embodiment, the moving path extends along the length direction of the shielding net 2. In this way, it can be ensured that the moving path of the camera 31 is relatively long and can completely cover the spatial area of the cooked food in the cooking cavity 11 as much as possible. The width of the shielding net 2 is greater than the lens diameter of the camera 31, ensuring that the image data formed by each shot of the camera 31 is complete in other directions except the moving path. The processor only needs to splice the image data in the moving direction.

[0045] In order to ensure the coverage area of the shielding net 2, the length of the shielding net 2 is not less than 150 mm, and the width of the shielding net 2 is not less than 10 mm. Specifically, it can be selected and set according to the size of the inner container 1. Under the above-mentioned coverage area of the shielding net 2, the length of the moving path of the camera 31 can be made not less than 50 mm, enabling multiple shots and providing more choices for the image data used for synthesis.

[0046] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
