Description

Technical Field

[0001] This utility model belongs to the field of cooking appliance technology, specifically relating to an oven with a camera device. Background Technology

[0002] Currently, some high-end ovens integrate cameras to facilitate user observation of food within the cooking cavity or to enable automatic cooking recognition. However, ovens generate high internal temperatures and produce significant amounts of steam and fumes during cooking. In existing technologies, cameras are typically mounted directly or through a simple glass pane facing the cooking cavity, resulting in significant heat dissipation issues. Sustained high-temperature operation can easily lead to camera overheating and damage, affecting lifespan and image stability. Simultaneously, steam or grease within the cooking cavity can condense on the single-layer glass surface, causing fogging or contamination, obstructing the field of view, blurring images, and impacting observation or recognition effectiveness. Furthermore, existing structures often fail to effectively block and dissipate heat along the heat transfer path between the camera and the cooking cavity, further exacerbating the deterioration of the camera's working environment. Therefore, a mounting structure for an oven camera that effectively isolates high temperatures, prevents glass fogging, and ensures stable camera operation is needed. Utility Model Content

[0003] This invention provides an oven with a camera device, aiming to solve the problems of existing camera devices being prone to overheating in the high temperature and humidity environment of the oven, the glass components being prone to fogging and contamination leading to poor shooting effect, and low working reliability.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An oven with a camera device includes:

[0006] The box body has a cooking cavity for holding food and a mounting part located outside the cooking cavity. A heat dissipation duct is provided between the mounting part and the side wall of the cooking cavity.

[0007] A camera device is mounted on the mounting portion and used to film the interior of the cooking cavity. A glass assembly is provided between the camera device and the cooking cavity, and the camera device films the interior of the cooking cavity through the glass assembly. The glass assembly includes a first glass disposed on the side wall of the cooking cavity and a second glass disposed on the mounting portion. A gap communicating with the heat dissipation duct is provided between the first glass and the second glass.

[0008] A heat dissipation device, which is connected to the heat dissipation duct.

[0009] A further embodiment: a first mounting hole is provided on the side wall of the cooking cavity, and the first glass is disposed at the first mounting hole; a second mounting hole is provided on the mounting part, and the second glass is disposed at the second mounting hole.

[0010] Based on the above technical solution: by setting independent first mounting holes and second mounting holes, the first glass and the second glass are installed respectively, which facilitates processing and assembly.

[0011] A further embodiment: A first annular groove is provided around the first mounting hole, recessed towards the inside of the cooking cavity, and a first sealing part is provided between the first glass and the first annular groove; a second annular groove is provided around the second mounting hole, recessed towards one side of the cooking cavity, and a second sealing part is provided between the second glass and the second annular groove.

[0012] Based on the above technical solution: the first sealing part and the second sealing part can respectively seal the installation edges of the first glass and the second glass, effectively preventing heat, steam or oil stains in the cooking cavity from leaking into the gap between the glass components or the outside of the installation part through the installation gap, thus ensuring the isolation effect and internal cleanliness.

[0013] A further solution: the first sealing part is silicone sealant or a sealing ring; the second sealing part is a sealing ring or silicone sealant.

[0014] Based on the above technical solution, specific implementation methods for the sealing part are provided, which can be flexibly selected according to process and cost requirements.

[0015] A further solution: the first mounting hole and the second mounting hole are coaxially arranged.

[0016] Based on the above technical solution: ensure that the shooting light path of the camera device is directly facing the inside of the cooking cavity to obtain the best shooting angle.

[0017] A further embodiment: the mounting part is installed on the upper side of the top wall of the cooking cavity, the camera device includes a mounting bracket, a circuit board and at least one camera, the mounting bracket is installed on the upper side of the mounting part, the circuit board and the camera are both installed on the mounting bracket, and a set of glass components is provided between each camera and the cooking cavity.

[0018] Based on the above technical solution: the entire camera device is mounted above the installation unit, resulting in a compact structure that facilitates installation and maintenance. Each camera corresponds to an independent set of glass components, ensuring that the shooting channel of each camera has good isolation and anti-fog performance.

[0019] A further embodiment: The top wall of the cooking cavity is provided with a first protrusion that is conically arched upward and gradually narrows from bottom to top. The first protrusion is formed by a top wall of the first protrusion and a surrounding wall of the first protrusion arranged around the lower side of the top wall of the first protrusion. The first glass is disposed on the top wall of the first protrusion.

[0020] Based on the above technical solution: the conical arched first protrusion design, on the one hand, gives the camera a wider shooting angle and can better capture the inside of the cooking cavity, and on the other hand, its inclined wall helps to guide any dripping condensate or oil stains to slide off, avoiding accumulation in the area directly in front of the camera and keeping the first glass clean. In addition, the upward arched structure makes the distance between the glass assembly and the camera device and the heating element in the oven greater, which can reduce the impact of heat radiation.

[0021] A further embodiment: The top wall of the mounting part is provided with a second protrusion that is conically arched upward and gradually narrows from bottom to top. The second protrusion is formed by a top wall of the second protrusion and a surrounding wall of the second protrusion arranged around the lower side of the top wall of the second protrusion. The second glass and the camera device are both disposed on the top wall of the second protrusion.

[0022] Based on the above technical solution: the second protrusion and the first protrusion provide a raised mounting platform for the second glass and the camera device, which helps to utilize space. Its sloping enclosure also helps to channel away any small amount of condensation that may occur.

[0023] A further embodiment: the top wall of the first protrusion and the top wall of the second protrusion are arranged parallel to each other, and the surrounding wall of the first protrusion and the surrounding wall of the second protrusion are arranged parallel to each other.

[0024] Based on the above technical solution: the parallel arrangement ensures that the gap thickness between the first glass and the second glass is uniform, which is conducive to the stable passage of heat dissipation airflow, forming an effective heat insulation air layer, while also ensuring the perpendicularity of the optical path and reducing image distortion.

[0025] A further embodiment: the heat dissipation device includes a first heat dissipation fan located at the rear side of the cooking cavity and / or a second heat dissipation fan located between the mounting portion and the top wall of the cooking cavity.

[0026] Based on the above technical solution, a power source for the heat dissipation duct is provided. Utilizing the oven's existing fan for cooling the cavity or components, or by adding a dedicated fan, cooling airflow is forced into the heat dissipation duct between the mounting section and the cooking cavity, flowing through the gap between the first and second glass panes. The flowing air continuously carries away heat conducted from the cooking cavity through the first glass pane, as well as heat from the outer surface of the second glass pane, significantly reducing the temperature transferred to the camera device and dehumidifying the gap space, preventing steam from condensing and fogging on the glass surface.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention utilizes a double-layered glass assembly comprising a first and a second glass layer between the camera device and the cooking cavity, with a gap between the two glass layers communicating with a heat dissipation duct. The flowing air within this gap forms a heat insulation and dehumidification barrier. This structure effectively blocks direct radiation and conduction of the high temperature from the cooking cavity to the camera device, and continuously reduces the temperature of the glass assembly and the humidity within the gap through forced air cooling. This prevents the camera from experiencing performance degradation or damage due to overheating, while also preventing fogging or oil contamination of the glass due to steam condensation, ensuring stable recording even under the high-temperature operating environment of the oven. Furthermore, the double-layered, independently sealed glass assembly enhances the structure's airtightness and reliability. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1 to 4 As shown, this embodiment provides an oven with a camera device, including:

[0038] The box 1 has a cooking cavity 11 for holding food and a mounting part 12 located outside the cooking cavity 11. The mounting part 12 covers the top wall of the cooking cavity 11 and leaves a certain gap between it and the top wall of the cooking cavity 11, thereby forming a surrounding heat dissipation duct 13.

[0039] A camera device 2 is disposed on the upper side of the mounting portion 12 and is used to photograph the interior of the cooking cavity 11. A glass assembly 3 is provided between the camera device 2 and the cooking cavity 11, and the camera device 2 photographs the interior of the cooking cavity 11 through the glass assembly 3. The glass assembly 3 includes a first glass 31 disposed on the side wall (top wall in this embodiment) of the cooking cavity 11 and a second glass 32 disposed on the mounting portion 12. A gap 33 is provided between the first glass 31 and the second glass 32, and the gap 33 communicates with the heat dissipation duct 13.

[0040] A heat dissipation device, which is connected to the heat dissipation duct 13 and is used to blow cooling airflow into the heat dissipation duct 13.

[0041] The cooking cavity 11 has a first mounting hole 14 on its top wall. A first annular groove 15 is provided around the first mounting hole 14, recessed towards the inside of the cooking cavity 11. The diameter of the first glass 31 is larger than the diameter of the first mounting hole 14, and it is sealed and fixed within the first annular groove 15 by a first sealing part, with the first glass 31 located above the first mounting hole 14. In this embodiment, the first sealing part is preferably high-temperature resistant silicone sealant.

[0042] The top wall of the mounting portion 12 is provided with a second mounting hole 34 coaxial with the first mounting hole 14. A second annular groove 35 is recessed around the second mounting hole 34 towards the cooking cavity 11. The diameter of the second glass 32 is larger than the diameter of the second mounting hole 34, and it is sealed and fixed within the second annular groove 35 by a second sealing part, with the second glass 32 located above the second mounting hole 34. In this embodiment, the second sealing part is preferably a sealing ring. The first and second sealing parts ensure that high-temperature steam and fumes inside the cooking cavity 11 do not leak into the gap 33 or above the mounting portion 12.

[0043] In some specific implementations, such as Figures 1 to 4 As shown, to optimize the structure and achieve better shooting and heat insulation effects, the top wall of the cooking cavity 11 is provided with a first protrusion 16 that is conically arched upwards and gradually tapers from bottom to top. The first protrusion 16 is formed by a first protrusion top wall 161 and a first protrusion surrounding wall 162 arranged around the lower side of the first protrusion top wall 161. The first mounting hole 14 and the first glass 31 are provided on the first protrusion top wall 161. Correspondingly, the top wall of the mounting part 12 is provided with a second protrusion 36 that is conically arched upwards and gradually tapers from bottom to top. The second protrusion 36 is formed by a second protrusion top wall 361 and a second protrusion surrounding wall 362 arranged around the lower side of the second protrusion top wall 361. The second mounting hole 34, the second glass 32, and the camera device 2 are all provided on the second protrusion top wall 361. The top wall 161 of the first protrusion and the top wall 361 of the second protrusion are parallel to each other, and the surrounding wall 162 of the first protrusion and the surrounding wall 362 of the second protrusion are parallel to each other, making the thickness of the gap 33 uniform. The conical bulge design of the first protrusion 16 and the second protrusion 36 allows the shooting angle of the camera device 2 to be raised and focused, making it easier to observe the panoramic view inside the cooking cavity 11; at the same time, the arched structure also keeps the installation position of the first glass 31 and the camera device 2 relatively far away from the heating tube inside the cooking cavity, and plays a certain auxiliary heat insulation role by utilizing air gaps and structural isolation.

[0044] In this embodiment, as Figures 1 to 4 As shown, the camera device 2 includes a mounting bracket 21, a circuit board 22, and a camera 23. The mounting bracket 21 is fixed above the mounting part 12 (specifically, the top wall 361 of the second protrusion). The circuit board 22 and the camera 23 are mounted on the mounting bracket 21, and the lens of the camera 23 faces the second glass 32, the gap 33, and the first glass 31 below.

[0045] The heat dissipation device includes a first cooling fan 41 located at the rear of the cooking cavity 11. This first cooling fan 41 is coaxially arranged with the oven's hot air fan used to circulate hot air through the cooking cavity 11, and both can share a motor drive. The first cooling fan 41 communicates with the heat dissipation duct 13 between the mounting portion 12 and the top wall of the cooking cavity 11.

[0046] As a further optimization, the heat dissipation device may also include a second cooling fan 42, which is preferably a volute fan. Its air outlet may also be connected to the heat dissipation duct 13, and the airflow generated may be directly blown onto the circuit board 22 of the camera device 2 to dissipate heat from the circuit board 22. The first cooling fan 41 may be specifically disposed inside the housing 1 and located on the rear side of the cooking cavity 11, and the second cooling fan 42 may be specifically disposed between the mounting part 12 and the top wall of the cooking cavity.

[0047] When the oven is working, the first cooling fan 41 (and optionally the second cooling fan 42) is activated, and the cooling airflow is blown into the cooling duct 13 and partially flows into the gap 33 between the first glass 31 and the second glass 32, forming a continuous airflow.

[0048] Working principle explanation:

[0049] During oven operation, high temperatures are generated inside the cooking cavity 11. The heat is initially transferred to the first glass 31, but due to the gap 33 between the first glass 31 and the second glass 32, and the cooling airflow driven by the heat dissipation device through the heat dissipation duct 13 and the gap 33, most of the heat is carried away, significantly reducing the temperature transferred to the second glass 32. Simultaneously, the flowing air also keeps the humidity within the gap 33 low. Even if a small amount of steam permeates through the first seal, it is carried away by the airflow and cannot condense on the inner surface of the second glass 32. Therefore, the camera device 2 is always in a relatively low-temperature, dry working environment, effectively avoiding overheating damage and lens fogging, and enabling better imaging of the food inside the cooking cavity 11.

[0050] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
