Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, specifically to a door device for cooking equipment and cooking equipment. Background Technology

[0002] In current cooking equipment, especially ovens, cameras are sometimes installed inside the appliance to monitor the cooking process. However, traditional camera installation methods typically involve fixing the camera to the top or side wall of the oven cavity. The camera's field of view is limited, making it difficult to clearly observe different levels of the oven cavity simultaneously, such as food placed on the upper and lower shelves. When food is obstructed by the grill rack or other food, a fixed camera cannot adjust its viewing angle, resulting in blind spots and failing to provide users with a comprehensive and clear image of the cooking process. Furthermore, directly exposing the camera to the high-temperature cooking cavity of the oven increases the risk of malfunction. While some movable cameras can move, the smoothness of the camera module's lifting and lowering is difficult to guarantee under conditions of frequent door opening and closing, thus affecting image acquisition quality and the accuracy of intelligent cooking. Utility Model Content

[0003] In view of this, the present invention provides a door device for cooking equipment and cooking equipment to solve the problems of limited field of view of the camera, blind spots in monitoring, and inability to provide users with comprehensive and clear images of the cooking status; and the fact that the camera is directly exposed in the high-temperature cooking cavity of the oven, which increases the risk of failure; and the inability to guarantee the smooth lifting of the camera module, which in turn affects the image acquisition quality and the accuracy of intelligent cooking.

[0004] In a first aspect, this utility model provides a door device for a cooking appliance, comprising: Door frame; At least two transparent panels are arranged parallel to each other on the door frame, with a cavity formed between the two transparent panels; The image acquisition module is disposed within the accommodating cavity; The driving mechanism includes a guide assembly, a transmission assembly, and a driving component; the guide assembly includes two racks, which are respectively disposed on opposite sides of the door frame and extend vertically; the transmission assembly is fixedly connected to the image acquisition module, and both ends of the transmission assembly are respectively drivenly engaged with the two racks; the driving component is drivenly connected to the transmission assembly.

[0005] Beneficial effects: The two transparent panels on the door frame form a cavity to house the image acquisition module, avoiding direct exposure to the high temperature and humidity cooking environment. This ensures a clear field of view while protecting the module and extending its lifespan. Simultaneously, the drive mechanism moves the image acquisition module parallel to the transparent panels, breaking the limitations of traditional fixed cameras. The camera angle can be flexibly adjusted according to the placement of multiple layers of food inside the oven, allowing for clear observation of the cooking status of different layers. By placing two racks on opposite sides of the door frame, coupled with the transmission connections at both ends of the drive assembly, bidirectional symmetrical guidance support is provided for the movement of the image acquisition module. This effectively prevents tilting and jamming during movement, ensuring the stability and accuracy of the module. This, in turn, guarantees precise angle adjustment and image stability. Furthermore, the symmetrical layout of the double racks enhances the overall structural load-bearing capacity and lifespan, making it suitable for ovens with frequent door opening and closing and drastic temperature changes.

This avoids direct exposure to the high temperature and humidity cooking environment, ensuring a clear field of view for observation while protecting the image acquisition module 13 and extending its service life. Simultaneously, the drive mechanism 14 can move the image acquisition module 13 in a direction parallel to the transparent panels 12, breaking the viewing angle limitations of traditional fixed cameras 131. It allows for flexible adjustment of the camera angle based on the placement of multiple layers of food inside the oven, thus enabling clear observation of different layers.

This ensures the stability and efficiency of power transmission, driving the image acquisition module 13 to move smoothly along the rack 1411 to accurately adjust the viewing angle. The symmetrical gear and rack 1411 transmission structure also avoids deviation and jamming during movement, ensuring the stability of the camera image and ensuring the smoothness of movement and the accuracy of the viewing angle positioning.

Together with the side frame 111 fixing the left and right sides of the inner transparent panel 1201, the inner transparent panel 1201 is installed and positioned in all directions, preventing it from shifting or loosening during door opening and closing or cooking vibrations. At the same time, the snap-fit ​​structure of the upper and lower frames 113 is simple and reliable, which facilitates the assembly and subsequent maintenance and replacement of the transparent panel 12.

[0064] In a specific embodiment, the upper frame 112 and the two side frames 111 are all flatly attached to the inner surface of the outer transparent panel 1202 and fixed with adhesive to ensure that the upper frame 112 and the two side frames 111 are tightly connected to the transparent panel 12 and are not easily displaced. At the same time, an inner support strip 1121 is fixed below the upper frame 112 with fasteners such as screws. The inner support strip 1121 and the lower frame 113 located at the bottom and connected to the two side frames 111 with screws work together to form an upper and lower clamping structure for the inner transparent panel 1201.

[0065] In one embodiment, the door device 1 for the cooking equipment further includes an operating member 15, which is fixed to the outer transparent panel 1202 away from the surface of the receiving cavity 121.

[0066] In the above embodiment, the operating component 15 is fixed on the side of the outer transparent panel 1202 away from the receiving cavity 121. This not only allows the user to directly contact the operating component 15 to open and close the door, avoiding burns from touching the area near the high-temperature cooking cavity 21, but also ensures that the operating component 15 does not interfere with the transparent panel 12, the image acquisition module 13 in the receiving cavity 121, and other components, and does not affect the movement and shooting field of the image acquisition module 13. At the same time, this external installation also facilitates the assembly, maintenance and replacement of the operating component 15, improving the safety and convenience of using the door.

[0067] Specifically, the operating component 15 is a handle.

[0068] Specifically, the operating component 15 is fixed to the surface of the outer transparent panel 1202 away from the receiving cavity 121 by fasteners such as screws.

[0069] Specifically, when the drive component 143 starts working, its power is transmitted to the drive shaft 1431 and drives the drive shaft 1431 to rotate. The drive shaft 1431 then drives the drive wheel 1432 to rotate synchronously. Since the drive wheel 1432 meshes with one of the transmission gears 1423, the rotation of the drive wheel 1432 will drive the transmission gear 1423 to rotate in the opposite direction. The two transmission gears 1423 are respectively fixed at both ends of the transmission shaft 1422. Under the linkage of the transmission shaft 1422, the transmission gear 1423 installed at the other end of the transmission shaft 1422 will also rotate synchronously. Meanwhile, the two transmission gears 1423 at both ends of the transmission shaft 1422 also mesh with the two racks 1411 fixedly installed on the door frame 11. Since the racks 1411 are fixed in position and cannot move, the two rotating transmission gears 1423 can only roll along the tooth surface on the racks 1411, thereby driving themselves and the transmission shaft 1422 connected to them to achieve vertical displacement. The image acquisition module 13 is fixedly connected to the support component 1421 where the transmission shaft 1422 is located. Finally, under the cooperation of the transmission gears 1423 and the racks 1411, the entire image acquisition module 13 is driven to achieve stable vertical movement, thereby flexibly adjusting the camera angle to cover different areas of the cooking cavity 21.

[0070] According to an embodiment of the present invention, another aspect provides a cooking device, including a cooking body 2 and the aforementioned door device 1 for the cooking device; the cooking body 2 has a cooking cavity 21 inside; the aforementioned door device 1 for the cooking device is hinged to the cooking body 2 and is used to open and close the cooking cavity 21.

[0071] In a specific implementation, the cooking cavity 21 is divided into multiple cavities. To address the problem that traditional fixed image acquisition modules 13 cannot simultaneously cover multiple cavities, resulting in incomplete observation of the food cooking process, this application sets up a movable image acquisition module 13, allowing a single camera 131 to dynamically adjust its spatial position as needed. This flexibly covers the observation angle of the multiple cavities of the cooking cavity 21, achieving comprehensive monitoring of the food state inside the cavity. This effectively solves the problem of limited observation range during multi-cavity cooking and improves the comprehensiveness and flexibility of monitoring the food cooking process.

[0072] Specifically, the door is hinged to the main body of the equipment via hinge 22.

[0073] Specifically, the two sets of hinges 22 are fixed to the main body of the equipment, and their transmission arms 221 are fixedly connected to the two side frames 111 of the door frame 11 respectively.

[0074] Specifically, to achieve a reliable connection, a first connection hole 1114 is provided on the side frame 111, and a corresponding second connection hole 222 is provided on the transmission arm 221. By passing screws and other fasteners through the first connection hole 1114 and the second connection hole 222 in sequence and locking them, the assembly of the door can be completed.

[0075] It should be noted that cooking equipment includes, but is not limited to, electric ovens, microwave ovens, steam ovens, and steam ovens.

[0076] In one embodiment, the cooking equipment includes a steam oven.

[0077] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
