Description
Technical Field
[0001] This utility model relates to the technical field of steam ovens, and in particular to a steam oven. Background Technology
[0002] A steam oven is an appliance that can both steam and bake food. Before using a steam oven, users need to rely on their cooking experience to pre-select and set the cooking mode, temperature, and time based on the type, weight, and volume of the ingredients, as well as different cooking requirements. This is crucial for producing delicious food. However, steam ovens demand a high level of cooking experience from users. Inexperienced users often need multiple failed attempts to succeed, reducing their confidence in using a steam oven. Furthermore, the operation is cumbersome and complex; different ingredients require different modes, temperatures, and times, which also diminishes the enjoyment of cooking.
[0003] To address this, steam ovens with cameras that recognize food have emerged. Based on the pain point of cumbersome cooking in steam ovens, the camera identifies the food, and the processor can intelligently identify the type, size, color, and weight of the ingredients based on the images captured by the camera. It then automatically selects the best cooking mode to intelligently cook the food, allowing even inexperienced users to cook delicious meals.
[0004] However, existing steam ovens place the camera inside the steaming cavity. When the cavity is filled with oil or steam, the camera's recognition is limited and it cannot accurately identify the food, which affects cooking. Moreover, since the camera is fixed, the photos and videos taken when identifying food are taken from a fixed angle, which limits the recognition. Utility Model Content
[0005] Therefore, it is necessary to provide a steam oven.
[0006] To solve the above-mentioned technical problems, this utility model provides a steam oven, including a cabinet, a steaming and baking cavity inside the cabinet, a rotating and opening door on the front of the cabinet, the maximum opening angle of the door being 90°, a slide rail and a baking tray for placing food inside the steaming and baking cavity, the slide rail including a first track and a second track, the first track being fixed to the cavity wall of the steaming and baking cavity, the second track being slidably connected to the first track, so that the slide rail can extend and retract along its length, the baking tray being placed on the second track, so that the baking tray moves with the second track from inside the steaming and baking cavity to above the opened door, a control module and an identification module for identifying food on the baking tray are provided on the cabinet, the identification module being electrically connected to the control module, and the identification module being located outside the steaming and baking cavity.
[0007] Preferably, the identification module is located directly above the door, and the identification module includes a camera.
[0008] Preferably, the enclosure and the door are respectively provided with door control switches for identifying the opening and closing of the door, and the door control switches are electrically connected to the control module.
[0009] Preferably, the first track is parallel to the second track, and the second track moves along the extension direction of the first track.
[0010] Preferably, there are two slide rails, which are respectively disposed on both sides of the cavity wall of the steam oven, and the two ends of the baking tray are detachably connected to the second tracks of the two slide rails.
[0011] Preferably, the second track is provided with an upward limiting opening, and the corresponding baking tray is provided with a limiting member, the size of which matches the size of the limiting opening, and the limiting member is located in the limiting opening.
[0012] Preferably, the second track is provided with an upward-facing limiting rod, and the corresponding baking tray is provided with a limiting hole. The size of the limiting member matches the size of the limiting opening, and the limiting rod is inserted into the limiting hole.
[0013] Preferably, the end of the second track near the box door is connected to the box door, so that the box door drives the second track to slide on the first track.
[0014] Preferably, the bottom end of the door is rotatably connected to the bottom end of the box body, a slide rail is provided on the inner side of the door, a slider is slidably connected on the slide rail, the end of the second track is connected to the slider, and the slider moves along the slide rail so that when the door is rotated to open and close, the slider moves along the slide rail to different positions on the slide rail.
[0015] Preferably, the end of the second track is rotatably connected to the slider.
[0016] The beneficial effects of this utility model are as follows: This utility model sets the identification module on the outside of the steam oven cavity and provides a retractable slide rail, which avoids the limitations of existing technologies where the identification device is directly exposed to the oil or steam environment inside the steam oven cavity. This reduces usage requirements and improves the identification effect. The baking tray is placed on the retractable slide rail, and the identification device takes real-time photos and videos of the food from multiple angles, making the identification of the food's weight and volume more accurate. This allows the control module to more accurately select the cooking mode, cooking temperature, and cooking time, making it easier to prepare delicious food. Attached Figure Description

[0024] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.
[0025] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0027] refer to Figures 1-5This utility model provides a steam oven, including a housing 1, a steaming and baking cavity inside the housing 1, and a rotating and opening door 2 on the front of the housing 1. The maximum opening angle of the door 2 is 90°. A slide rail 3 and a baking tray 4 for placing food are provided inside the steaming and baking cavity. The slide rail 3 includes a first track 31 and a second track 32. The first track 31 is fixed to the cavity wall of the steaming and baking cavity, and the second track 32 is slidably connected to the first track 31, so that the slide rail can extend and retract along its own length. The baking tray 4 is placed on the second track 32, so that the baking tray 4 moves with the second track 32 from inside the steaming and baking cavity to above the opened door 2. A control module and an identification module for identifying food on the baking tray 4 are provided on the housing 1. The identification module is electrically connected to the control module and is located outside the steaming and baking cavity. As the baking tray 4 slides into the steam oven cavity along the second track 32, the food on the baking tray 4 passes directly below the recognition module. This means that the recognition module starts from one side of the food and continuously scans and recognizes it from different angles until the food moves to the other side of the recognition module. At this point, the door 2 closes and stops taking pictures and video recognition. This allows for more accurate food recognition, enabling the control module to call up more precise cooking modes, temperatures, and times to steam and bake the food. Moreover, placing the recognition module outside the steam oven cavity avoids the harsh environment of steam and oil inside the cavity, making its use unrestricted. This breaks through the limitations of existing technology that installs cameras and other recognition devices in the steam oven cavity, avoiding the recognition limitations caused by oil or steam inside the cavity. It also lowers the usage requirements and improves the recognition effect.
[0028] refer to Figure 1 and Figure 3 In a preferred embodiment, the identification module is located directly above the door 2, and the identification module includes a camera 5. One side of the steaming and baking cavity of the oven body 1 has an opening, and the door 2 is installed at the opening of the steaming and baking cavity. The camera 5 of the identification module is positioned at the opening of the steaming and baking cavity of the oven body 1, directly above the door 2. After the door 2 is opened, the baking tray 4 is pulled outwards, causing the second track 32 to slide out of the steaming and baking cavity along with the baking tray 4. At this time, the second track 32, along with the baking tray 4, is located directly above the open door 2.
[0029] refer to Figure 1In a preferred embodiment, the cabinet 1 and the door 2 are respectively provided with door control switches 6 for identifying the opening and closing of the door. The door control switches 6 are electrically connected to the control module. The door control switches 6 can identify whether the door 2 is open or closed. When the door control switches 6 identify that the door 2 is open, the camera 5 starts working. After the food is placed on the baking tray, as the door 2 rotates and gradually closes, the baking tray 2 moves into the steaming and baking cavity along the slide rail. The camera 5 scans the food on the baking tray. During the movement of the baking tray 2, the scanning angle of the camera 5 on the food on the baking tray gradually changes, and the recognition result is more accurate. When the door control switches 6 identify that the door 2 is closed, the camera 5 stops working, and the scanning is completed.
[0030] refer to Figure 3 In a preferred embodiment, the first track 31 is parallel to the second track 32, and the second track 32 moves along the extension direction of the first track 31.
[0031] refer to Figure 3 In a preferred embodiment, there are two slide rails 3, which are respectively disposed on both sides of the cavity wall of the steam oven cavity. The two ends of the baking tray 4 are detachably connected to the second rails 32 of the two slide rails 3. The baking tray 4 is mounted on the two slide rails 3.
[0032] In a preferred embodiment, the second track 32 is provided with an upward-facing limiting opening, and the corresponding baking pan 4 is provided with a limiting member. The size of the limiting member matches the size of the limiting opening, and the limiting member is located within the limiting opening. During placement, the baking pan 4 is placed on the second track 32 from above, and the limiting member on the baking pan 4 is aligned with the limiting opening on the second track 32, so that the limiting member is located within the limiting opening. This restricts the baking pan 4 onto the second track 32, preventing it from shifting. Optionally, the limiting member is a protrusion located at the bottom of the baking pan 4, which is fitted into the limiting opening to limit the baking pan 4.
[0033] refer to Figure 2 In a preferred embodiment, the second track 32 is provided with an upward-facing limiting rod 71, and the corresponding baking tray 4 is provided with a limiting hole 72. The size of the limiting rod 71 matches the size of the limiting hole 72, and the limiting rod 71 is inserted into the limiting hole 72. During placement, the baking tray 4 is placed on the second track 32 from above, with the limiting hole 72 on the baking tray 4 aligned with the limiting rod 71 on the second track 32, so that the limiting rod 71 is located within the limiting hole 72. This restricts the baking tray 4 onto the second track 32, preventing it from shifting.
[0034] refer to Figure 1 and Figure 3 In a preferred embodiment, the end of the second track 32 near the door 2 is connected to the door 2, so that the door 2 drives the second track 32 to slide on the first track 31.
[0035] The inside of the oven door 2 is connected to the second track 32, which is slidably connected to the oven body 1. The baking tray 4 is placed on the second track 32. The second track 32 enters the steam oven cavity of the oven body 1 or slides out from the steam oven cavity under the action of the oven door 2, thereby realizing the opening and closing of the steam oven. The oven door 2 is used to close or open the opening end of the steaming and baking cavity of the oven body 1, with one side of the steaming and baking cavity being the opening end. The baking tray 4 enters the steaming and baking cavity from the opening end of the oven body 1 and is detachably connected to the second track 32. The baking tray 4 is placed vertically on the second track 32 or removed from the second track 32. This makes the operation more convenient as the baking tray 4 enters the steaming and baking cavity of the oven body 1 with the oven door 2 or slides out of the steaming and baking cavity. It eliminates the need to open the oven door 2 first and then pull out the baking tray 4. Using the structure of this embodiment, when the oven door 2 is opened, the baking tray 4 slides out of the steaming and baking cavity with the oven door 2. Moreover, it is more convenient to place and take food from the baking tray 4. During the process of placing and taking food, the oven body 1 and the heating tube in the steaming and baking cavity of the oven body 1 also reduce the risk of burns to the hands during operation.
[0036] In a preferred embodiment, the bottom end of the door 2 is rotatably connected to the bottom end of the box body 1. A slide is provided on the inner side of the door 1. The extension direction of the slide is parallel to the plane where the rotation direction of the door 2 is located. A slider is slidably connected on the slide. The end of the second track 32 is connected to the slider. The slider moves along the slide, so that when the door 2 rotates to open and close, the slider moves along the slide to different height positions of the slide.
[0037] In a preferred embodiment, the end of the second track 32 is rotatably connected to the slider. The end of the second track 32 is connected to the slider via a hinge.
