Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a steam oven. Background Technology
[0002] Currently, steam ovens equipped with cameras to monitor food status typically mount the camera module inside the oven or on the door.

[0029] The steam oven provided by this utility model will be described below with reference to specific embodiments.
[0030] Figure 1 A schematic diagram of the structure of a steam oven provided by an embodiment of the present invention is shown. For ease of explanation, only the parts related to the embodiment of the present invention are shown.
[0031] In this embodiment of the present invention, the steam oven may include at least a cabinet 1, a door and an image acquisition device, wherein the door may include at least a first glass door panel 21 and a second glass door panel 22, and the image acquisition device may include at least an imaging module 31 and an image processor 32.
[0032] The cabinet 1 has an opening, and the door is used to cover the opening of the cabinet 1. When the door covers the cabinet 1, the door and the cabinet 1 form a sealed fit to form a cooking cavity 11.
[0033] The first glass door panel 21 and the second glass door panel 22 are arranged at intervals relative to each other, that is, the first glass door panel 21 and the second glass door panel 22 are parallel and have a certain interval, and a first heat insulation cavity 23 is formed between the first glass door panel 21 and the second glass door panel 22.
[0034] The imaging module 31 is electrically connected to the image processor 32. The imaging module 31 is disposed in the cooking cavity 11, and the image processor 32 is disposed in the first heat insulation cavity 23.
[0035] This utility model embodiment adopts a split-structure image acquisition device, in which the imaging module and image processor are respectively set in different areas of the steam oven. The image processor is located in the heat insulation area formed by the steam oven door, and the imaging module is located in the cooking area of the steam oven. There is no obstruction between the imaging module and the object to be processed in the cooking area, thereby improving the imaging quality, enhancing the user experience, and reducing the high temperature resistance requirements of the image processor, thus reducing the cost of the steam oven.
[0036] The imaging module 31 may include at least a lens and an image sensor. The lens is electrically connected to the image sensor and guides light onto the image sensor. The image sensor converts the light signal acquired by the lens into an electrical signal and transmits the electrical signal to the image processor 32. The image processor 32 extracts and optimizes image information from the raw data output by the image sensor, and finally outputs an image that can be displayed, stored, or further processed. The imaging module 31 and the image processor 32 can be connected by a flexible cable, such as an FPC (Flexible Printed Circuit) cable. Because flexible cables have advantages such as bend resistance and high flexibility, this embodiment of the invention utilizes a flexible cable to connect a separate image acquisition device, making the separate image acquisition device suitable for applications such as steam ovens.
[0037] like Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a steam oven body and door provided in an embodiment of the present invention. The first glass door panel 21 is disposed on the side near the cooking cavity 11, and the second glass door panel 22 is disposed on the side away from the cooking cavity 11. The second glass door panel 22 has a first surface 221 located within the first heat insulation cavity 23. The first glass door panel 21 also has a second surface 211, which is the surface of the first glass door panel 21 closest to the cooking cavity 11. When the steam oven is in operation, the temperature inside the cooking cavity 11 is approximately 140°C, the temperature at the first surface 221 is approximately 60°C, and the temperature of the interlayer air in the first heat insulation cavity 23 is approximately 75°C. Therefore, by disposing of the image processor 32 on the first surface 221, this embodiment of the present invention can reduce the high-temperature resistance requirements of the image processor 32, allowing the image processor 32 to be a consumer-grade image processor, thereby reducing the cost of the steam oven.
[0038] The imaging module 31 can be disposed on the inner surface of the housing 1, such as... Figure 1 As shown, since the imaging module 31 is located inside the cooking cavity 11 at a high temperature, the imaging module 31 may include an automotive-grade lens and an image sensor. In this embodiment of the invention, there is no obstruction between the imaging module 31 and the object 5 to be processed within the cooking cavity 11, thereby improving image quality and enhancing the user experience.
[0039] The door may also include a handle 4, which is disposed on the surface of the second glass door panel 22 away from the first heat insulation cavity 23.
[0040] Generally, for image acquisition devices, automotive-grade and consumer-grade solutions differ in their focusing methods. Automotive-grade solutions typically use fixed focus (FF), while consumer-grade solutions often use autofocus (AF). This embodiment uses an AF-type control scheme within an FF-type imaging module. Before the oven leaves the factory, the distance between the lens and the object to be processed 5 is adjusted based on the lens's fixed focal length. This determines the position of the imaging module 31 on the inner surface of the housing 1, ensuring that the lens image includes the area where the object to be processed 5 is placed, thus clearly capturing the object 5 inside the oven.
[0041] In another embodiment of this utility model, Figure 3 A schematic diagram of the structure of a steam oven provided in an embodiment of this utility model is shown below. Figure 2 and Figure 3 As shown, the imaging module 31 can also be disposed on the second surface 211. In this embodiment of the invention, there is no obstruction between the imaging module 31 and the object to be processed 5 in the cooking cavity 11, thereby improving the imaging quality and enhancing the user experience.
[0042] It should be noted that when the lens in the imaging module 31 is of the fixed focus type, the specific position of the imaging module 31 on the second surface 211 needs to be determined according to the fixed focal length of the lens in the imaging module 31. Specifically, before the steam oven leaves the factory, the distance between the lens and the object to be processed 5 is adjusted based on the fixed focal length of the lens, thereby determining the position of the imaging module 31 on the second surface 211, so that the lens image includes the placement area of the object to be processed 5, and can clearly capture the object to be processed 5 inside the steam oven.
[0043] In another embodiment of this utility model, Figure 4 A schematic diagram of the structure of a steam oven provided in an embodiment of this utility model is shown below. Figure 4 As shown, the imaging module 31 can also be mounted inside the housing 1 via a bracket. In this embodiment of the invention, there is no obstruction between the imaging module 31 and the object to be processed 5 within the cooking cavity 11, thereby improving image quality and enhancing the user experience.
[0044] It should be noted that when the lens in the imaging module 31 is of the fixed focus type, the specific position of the imaging module 31 inside the housing 1 needs to be determined according to the fixed focal length of the lens in the imaging module 31. Specifically, before the steam oven leaves the factory, the distance between the lens and the object to be processed 5 is adjusted based on the fixed focal length of the lens, thereby determining the position of the imaging module 31 inside the housing 1, so that the lens image includes the placement area of the object to be processed 5, and can clearly capture the object to be processed 5 inside the steam oven.
[0045] In another embodiment of the present invention, the door body may further include at least one third glass door panel 24, which is disposed between the first glass door panel 21 and the second glass door panel 22. The at least one third glass door panel 24 is disposed opposite to the first glass door panel 21 and the second glass door panel 22, that is, the first glass door panel 21, the second glass door panel 22 and the at least one third glass door panel 24 are parallel to each other and have a certain interval. A second heat insulation cavity 25 is formed between the second glass door panel 22 and the third glass door panel 24 closest to the second glass door panel 22. The image processor 32 is disposed in the second heat insulation cavity 25. Figure 5 This is a structural schematic diagram of the oven body and door of a steam oven provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the door body includes a first glass door panel 21, a second glass door panel 22, and a third glass door panel 24. The third glass door panel 24 is disposed between the first glass door panel 21 and the second glass door panel 22, and is used for further heat insulation. A second heat insulation cavity 25 is formed between the second glass door panel 22 and the third glass door panel 24. The image processor 32 is disposed within the second heat insulation cavity 25. To minimize the temperature of the environment in which the image processor 32 is located, the image processor 32 can be disposed on the first surface 221. This embodiment of the invention improves the heat insulation effect by providing two or more glass door panels within the door body of the steam oven. By placing the image processor 32 in the heat insulation cavity furthest from the cooking cavity 11, the temperature of the environment in which the image processor 32 is located is further reduced, lowering the high-temperature resistance requirements for the image processor 32 and thus reducing the cost of the steam oven. Simultaneously, using multiple glass door panels for heat insulation prevents users from being burned while using the steam oven, improving the user experience.
[0046] In another embodiment of this utility model, in order to further reduce the temperature of the environment where the image processor 32 is located and ensure the normal operation of the image processor 32, a heat dissipation component can also be provided in the steam oven. The heat dissipation component may include a heat dissipation fan, which has an air inlet and an air outlet. The air inlet is disposed on the second glass door panel 22, and the air outlet faces the image processor 32 to dissipate heat from the image processor 32. The heat dissipation fan draws in ambient air from outside the door and causes the ambient air to flow towards the image processor 32. The heat dissipation fan and the image processor 32 can... The heat dissipation assembly, with its components respectively located at the bottom and top of the first surface 221 of the second glass door panel 22, may further include a diversion duct for directing airflow from the heat dissipation fan to the image processor 32. The heat dissipation assembly may also include a collector for covering the air inlet of the heat dissipation fan and forming a downward-opening collection port, allowing the heat dissipation fan to draw in ambient air only from below. The heat dissipation assembly may also include a fan bracket, which is fixedly connected to the heat dissipation fan and the second glass door panel 22. The heat dissipation fan may be a single-suction centrifugal fan. This embodiment of the invention, by providing a heat dissipation assembly in the door of the steam oven, can dissipate heat from the image processor 32, further reducing the temperature of the environment in which the image processor 32 is located, thus reducing the high-temperature resistance requirements of the image processor 32 and lowering the cost of the steam oven.
[0047] In another embodiment of this invention, the steam oven may further include a display device electrically connected to the image processor 32. The display device may be disposed on the outer surface of the steam oven and is used to display an image of the food to be processed 5 inside the steam oven. Specifically, the image processor 32 extracts and optimizes image information from the raw data output by the image sensor and outputs a displayable image to the display device. This embodiment of the invention provides a display device on the steam oven, allowing users to see the status of the food inside the oven in real time and clearly, understand the cooking progress, and improve the user experience.
[0048] In another embodiment of this utility model, the steam oven may further include a wireless communication device. The wireless communication device is electrically connected to the image processor 32 and communicatively connected to a terminal. The wireless communication device is used to transmit image information from inside the steam oven to the user's terminal via wireless communication. The wireless communication device may be a Bluetooth module or a radio frequency module; that is, the image information from inside the steam oven can be transmitted to the user's terminal via Bluetooth or WiFi. The terminal may include electronic devices such as mobile phones or tablets. This embodiment of the utility model provides a wireless communication device inside the steam oven, enabling the transmission of image information from inside the steam oven to the user's terminal. This allows the user to see the status of the food inside the steam oven in real time and clearly, understand the cooking progress, and improve the user experience. Furthermore, based on the received image information from inside the steam oven, the user can remotely control the steam oven via the terminal, such as setting programs, adjusting time or temperature, etc., improving the convenience of using the steam oven.
