Description

Technical Field

[0001] This utility model relates to an image acquisition device, which is applied to a steamer and oven. The present invention also relates to a steamer and oven with an image acquisition device. Background Technology

[0002] With the development of AI technology, installing cameras inside steam ovens, microwave ovens, and refrigerators to help determine the cooking level, preservation time, and freshness of food has become a foreseeable emerging technology. Currently, some home appliance manufacturers have already produced refrigerators, ovens, microwave ovens, and steam ovens with image acquisition devices based on this concept. However, steam ovens and microwave ovens still have a major problem with defogging, and refrigerators can also suffer from unclear images due to micro-frost buildup inside.

[0003] In the security and automotive industries, heating with electric heating wires is often used for defogging. However, this method can obstruct camera imaging, and the heating speed is very slow on the outer edges. Another solution uses ITO (Indium Tin Oxide) to heat glass, but ITO glass is difficult to heat above 130°C and cannot withstand the high temperatures of over 200°C in ovens. Therefore, there is currently no relatively good solution in the home appliance industry.

[0004] In addition, considering the need for sealing and safety, steam ovens and ovens typically use point light sources to illuminate the interior. This can easily cause localized exposure points in the camera, leading to problems and errors in image recognition, which needs to be improved. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide an additional image acquisition device for defogging, in view of the above-mentioned technical status quo.

[0006] The second technical problem to be solved by this utility model is to provide an image acquisition device with accurate image recognition in light of the above-mentioned technical status quo.

[0007] The third technical problem to be solved by this utility model is to provide a steam oven with clear images in view of the above-mentioned technical status quo.

[0008] The fourth technical problem to be solved by this utility model is to provide an oven with clear images in view of the above-mentioned technical status quo.

[0009] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: an image acquisition device, including a glass panel and a camera housing disposed on the back of the glass panel, wherein a camera capable of acquiring images inside the glass panel is provided inside the camera housing, characterized in that a heatable graphene transparent glass is provided on the back of the glass panel, and the graphene transparent glass is located in front of the camera.

[0010] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: the camera housing is provided with a polarizer that can selectively transmit light in a specific direction, and the polarizer is located between the camera and the graphene transparent glass.

[0011] Furthermore, the camera's image-capturing end is sealed within the space formed by the camera housing and the polarizer.

[0012] Preferably, the distance between the polarizer and the graphene transparent glass is at least 20 mm.

[0013] Furthermore, the graphene transparent glass and the back of the glass panel are encapsulated together using high-temperature resistant transparent silicone.

[0014] Furthermore, the front port of the camera housing is coated with adhesive and fixed to the back of the glass panel, while the graphene transparent glass is located inside the front port of the camera housing.

[0015] The technical solution adopted by this utility model to solve the third technical problem mentioned above is: a steam oven with an image acquisition device, wherein the back of the glass panel of the image acquisition device is provided with a heatable graphene transparent glass, which is located in front of the camera.

[0016] The technical solution adopted by this utility model to solve the fourth technical problem mentioned above is: an oven with an image acquisition device. The back of the glass panel of the image acquisition device is provided with a heatable graphene transparent glass, which is located in front of the camera.

[0017] Compared with existing technologies, the advantages of this invention are as follows: the graphene transparent glass can operate continuously at 400℃ for over 1000 hours; simultaneously, the heating speed of graphene material is much higher than that of resistance wire, reaching 120℃ in 5-8 seconds and 230℃ within 30 seconds. It can heat 4mm tempered glass to over 100℃ in 45 seconds, while the steam inside the steam chamber has not yet risen, ensuring that the area visible to the camera remains dry and clear throughout the process. This solves the problems of slow heating and opacity, achieving rapid heating and rapid defogging. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 The steam oven 10 shown. The door panel 1 of the steam oven has a double layer, and the inner side of the door panel 1 is a glass panel.

[0024] Combination Figure 2 , Figure 3 and Figure 4 As shown, a camera housing 2 is provided on the back of the glass panel 11. A camera 3 capable of capturing images inside the glass panel 11 is provided inside the camera housing 2. A heatable graphene transparent glass 5 is provided on the back of the glass panel 11, and the graphene transparent glass 5 is located in front of the camera 3.

[0025] The camera housing 2 is equipped with a polarizer 4 that selectively transmits light from a specific direction. This polarizer 4 is located between the camera 3 and the graphene transparent glass 5. The polarizer 4 adjusts the polarization direction by 90 degrees to the direction of most easy exposure, solving the problem of localized exposure of food and achieving a clear image. Specifically, a polarizer is an optical element that can selectively transmit light with a specific vibration direction, based on the phenomenon of light polarization. Specifically, the polarizer achieves selective transmission of light from a specific direction through its internal molecular structure or arrangement, while absorbing or blocking light from other directions, thus converting natural light into polarized light. Since the oven interior has a single light source, the relatively interference area is fixed. The angle can be adjusted directly during packaging to significantly reduce exposure problems caused by point light sources.

[0026] The distance between the polarizer 4 and the graphene transparent glass 5 is at least 20 mm to prevent the graphene glass from overheating and damaging the polarization structure of the polarizer.

[0027] The camera end of camera 3 is sealed within the space formed by camera housing 2 and polarizer 4, which can reduce the entry of moisture.

[0028] The graphene transparent glass 5 is integrally encapsulated with the back of the glass panel 11 using high-temperature resistant transparent silicone. The front port of the camera housing 2 is coated with adhesive and fixed to the back of the glass panel 11, while the graphene transparent glass 5 is located inside the front port of the camera housing 2. The continuous graphene layers in the graphene transparent glass 5 are completely isolated from the air, thus preventing the graphene material from contacting oxygen and oxidizing at high temperatures, and allowing for better heat transfer to the glass panel.

[0029] Graphene transparent glass has the following advantages: First, it is transparent, allowing cameras to observe the interior of the enclosure through it; second, it heats more evenly and faster than resistance wire and ITO heated glass; third, it has better high-temperature resistance, strong stability after being sealed in an air-isolated environment, and longer operating time.

[0030] The image acquisition device in this embodiment consists of a glass panel, a camera housing, a camera, a polarizing filter, and graphene transparent glass. Of course, the image acquisition device in this embodiment can also be applied to a steam oven or a steam-grill combination appliance; specifically, besides being located on the door panel, it can also be located on the side or top of the inner liner, which will not be elaborated further here.
