Description

Technical Field

[0001] This utility model belongs to the field of oven technology, specifically a device for preventing damage to the internal electronic components of a composite oven. Background Technology

[0002] With the increasing popularity of smart homes, multi-functional ovens, which integrate baking, microwave heating, and other functions, are becoming key electronic components for illuminating the oven interior, monitoring cooking progress in real time, and optimizing the cooking experience. However, the high-intensity microwaves (especially in the 2.4GHz frequency range) generated by microwave ovens during operation may penetrate unshielded materials, interfering with the camera and supplementary light, causing image distortion, signal interruption, flickering or extinguishing of the supplementary light, and even damage to the camera and supplementary light.

[0003] To address this issue, current ovens typically incorporate light-transmitting holes smaller than 4mm in diameter in the cavity where cameras and supplemental lighting are installed. This prevents microwaves from penetrating the holes and interfering with the cameras and lighting. However, such small holes can affect the camera's shooting angle, thus impacting image quality. Furthermore, small holes for supplemental lighting can lead to insufficient internal oven illumination, limited visibility, and localized shadows. Adding numerous supplemental lights to the oven may increase maintenance costs, and the space required for these lights could reduce usable space within the oven, limiting the placement and quantity of food. Utility Model Content

It effectively avoids camera image distortion, limited shooting angles, flickering or extinguishing of supplementary lights, and even damage, ensuring the normal operation of these components during cooking. Furthermore, this device extends the lifespan of these components and improves user safety.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a damage prevention device for electronic components inside a composite oven, including an oven metal cavity, a light-transmitting hole and conductive glass. The oven metal cavity is provided with a light-transmitting hole, and the conductive glass is fixedly installed in the light-transmitting hole. The conductive glass (3) is installed in front of the camera. When the oven is in working condition, the oven metal cavity and the conductive glass can form a complete Faraday cage.

[0006] Preferably, the conductive glass is covered with a conductive film on the side closest to the interior of the oven's metal cavity, and the edge of the conductive film is connected to the inner wall of the light-transmitting hole to form a continuous conductive path.

[0007] Preferably, the conductive film is a polyester film.

[0008] Preferably, the outer surface of the conductive film is coated with a conductive layer with a thickness of approximately 50nm-100nm.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0023] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0024] This utility model proposes a device to prevent damage to the electronic components inside a composite oven.

[0025] like Figure 1-4As shown in one embodiment of this utility model, the anti-damage device for the internal electronic components of the composite oven includes an oven metal cavity 1, a light-transmitting hole 2, and conductive glass 3. The oven metal cavity 1 is not fully shown in the figure; different shapes of metal cavities can be selected according to usage requirements. The oven metal cavity 1 is provided with a light-transmitting hole 2, and the conductive glass 3 is fixedly installed inside the light-transmitting hole 2, located in front of the camera. When the oven is in operation, the oven metal cavity 1 and the conductive glass 3 can form a complete Faraday cage structure. The use of conductive glass 3 can effectively shield 2.4GHz high-frequency microwave radiation, protecting the camera, supplementary lighting, and other electronic components from microwave interference. This effectively avoids camera image distortion, limited shooting angles, flickering or extinguishing of supplementary lighting, and even damage, ensuring the normal operation of the camera, supplementary lighting, and other electronic components during the cooking process. At the same time, it extends the service life of the camera, supplementary lighting, and other electronic components, improving user safety.

[0026] like Figure 3 , 4 As shown, the conductive glass 3 is covered with a conductive film 31 on the side closest to the interior of the oven's metal cavity 1. The edge of the conductive film 31 is connected to the inner wall of the light-transmitting hole 2 to form a continuous conductive path, ensuring that microwave energy is effectively guided to the grounding system and avoiding sparks or electromagnetic leakage at the edge of the glass, which could damage human health and electronic equipment. The connection should be waterproofed and moisture-proofed to enhance durability.

[0027] The conductive glass 3 is tightly connected to the metal wall of the oven's metal cavity 1 via conductive adhesive or metal clamps, so that the edge of the conductive film 31 is connected to the inner wall of the light-transmitting hole 2 to form a continuous conductive path. When the oven is in operation, the oven's metal cavity 1 and the conductive glass 3 can form a complete Faraday cage structure, effectively blocking microwave penetration.

[0028] Specifically, the conductive film 31 uses a polyester film as the substrate and has a conductive layer 32 coated on its outer surface. The conductive layer 32 uses a metal oxide with high conductivity and high light transmittance, such as indium tin oxide or indium zinc oxide, with a thickness of about 50nm-100nm. It can effectively shield microwaves without affecting the camera's line of sight and imaging quality, and also without affecting the use of the supplementary light.

[0029] The conductive layer 32 is coated with a dielectric layer 33. The dielectric layer 33 is made of high-temperature resistant and low-loss ceramic coating to ensure that it will not melt or degrade under long-term high temperature and microwave action, and further enhances the ability to block microwaves. The thickness of the dielectric layer 33 is about 50μm, ensuring long-term stable operation in high-temperature environment.

[0030] The conductive glass 3 is designed in a circular shape with a diameter of 13mm and a thickness of 1mm. This size is suitable for different types of cameras and fill lights, ensuring that it can completely cover and protect the camera lens and fill light, while not excessively increasing the space occupied inside the oven, maintaining the overall compact design.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
