Description

Technical Field

[0001] This application relates to the field of kitchen range hood technology, specifically to a UV fume hood with fresh air intake. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly remove the waste from the stove and the harmful fumes produced during cooking, exhausting them outdoors, reducing pollution, purifying the air, and providing safety features such as protection against poisoning and explosions.

[0003] In the kitchen environment, the range hood is an important component of the range hood. The range hood is mainly used to collect and guide the oil fumes generated during cooking. The steam generated during cooking will condense into water droplets on the surface of the range hood. If these water droplets cannot be discharged in time, they will accumulate, which will easily cause the surface of the range hood to be damp, leading to rust on the structure of the range hood, causing damage, and reducing the efficiency and lifespan of the range hood.

[0004] Therefore, the structure of the existing fume hoods has room for further improvement. Utility Model Content

[0005] In view of this, and addressing the technical problem in existing technologies that steam generated during cooking condenses into water droplets that easily accumulate on the surface of the range hood, leading to rust and reducing its efficiency and lifespan, this application provides a UV range hood with fresh air intake. By changing the structure of the range hood, water droplets can be quickly drained away, effectively preventing water droplets from accumulating on the surface of the range hood. It also allows the light from the lamps to be evenly distributed on the stovetop, improving visual clarity, increasing the efficiency of the range hood, and extending its lifespan.

Therefore, the above terms should not be construed as limitations on this application.

[0053] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 3 illustrate.

[0054] This embodiment provides a UV fume hood with integrated fresh air supply, which is applied in the field of kitchen range hood technology. Specifically, as shown in... Figures 1 to 3 As shown, the system includes a lighting device 1, a fresh air system 2, and an exhaust system 3. The fresh air system 2 is located on one side of the lighting device 1, and its side near the lighting device 1 has an inclined structure and a fixing plate 21. The lower end of the fixing plate 21 has a collection groove 22, which is used to collect water droplets formed by water vapor condensation, preventing water droplets from adhering to the surface of the lighting device 1. The fresh air system 2 can introduce fresh air, dilute the concentration of oil fumes in the kitchen, improve indoor air circulation, and reduce the irritation of oil fumes to the human body. The exhaust system 3 is located on the other side of the lighting device 1, and its side near the lighting device 1 has an inclined structure. The exhaust system 3 can achieve efficient exhaust of oil fumes and avoid oil fume retention.

[0055] Among them, such as Figure 1As shown, the side of the lighting device 1 connected to the fixing plate 21 is inclined, and the lighting device 1 is inclined toward the collection tank 22. The steam generated during cooking is easy to condense into water droplets and adhere to the surface of the fume hood. The inclined setting allows the water droplets to flow quickly into the collection tank 22 along the inclined surface, which can effectively prevent water droplets from accumulating on the surface of the fume hood and keep the fume hood dry. In addition, the inclined setting can ensure that the lighting light is more concentrated and more evenly illuminating the stove area, which can optimize the incident angle of the light, make the light more evenly illuminate the stove, improve visual clarity, help the chef accurately judge the state of the food, improve visibility during cooking, improve the efficiency of the fume hood and extend the life of the fume hood.

[0056] Furthermore, such as Figures 1 to 3 As shown, the lighting device 1 includes a lampshade plate 11 and a light box 12 mounted on the lampshade plate 11.

One end of the lampshade plate 11 is connected to a fixing plate 21, and the other end of the lampshade plate 11 is connected to an exhaust mechanism 3. An angle is formed between the lampshade plate 11 and the fixing plate 21. The angle design can better guide the light, so that the light can illuminate the stove more evenly. Among them, the angle between the lampshade plate 11 and the fixing plate 21 is an obtuse angle. The obtuse angle allows water droplets to flow quickly into the collection tank 22 along the inclined surface, which can effectively prevent water droplets from accumulating on the surface of the hood and keep the hood dry.

[0057] Among them, such as Figure 3 As shown, the fixing plate 21 includes a first shielding plate 211 and a second shielding plate 212. One end of the first shielding plate 211 is connected to the air supply top plate 23, and the other end of the first shielding plate 211 is fixedly connected to the second shielding plate 212. The lampshade plate 11 is connected to the side of the first shielding plate 211 away from the air supply plate 24. The lampshade plate 11 is located at the end of the first shielding plate 211 near the second shielding plate 212. The connection angle between the lampshade plate 11 and the second shielding plate 212 is an obtuse angle. The first shielding plate 211 is arranged parallel to the air supply plate 24, and the connection angle between the first shielding plate 211 and the second shielding plate 212 is an obtuse angle.

[0059] Furthermore, such as Figure 2 As shown, the fresh air mechanism 2 also includes a base plate 25 and side fixing plates 26 disposed on both sides of the fixing plate 21. The base plate 25 has a U-shaped structure and is located below the side fixing plates 26. The side fixing plates 26 are at least partially connected to the side of the air supply top plate 23, at least partially connected to the side of the air supply plate 24, and at least partially connected to the base plate 25. The base plate 25 and the air supply plate 24 are detachably connected, and the base plate 25 and the side fixing plates 26 are detachably connected. This detachable connection facilitates the disassembly and cleaning of the fresh air mechanism 2, improving ease of use and maintenance. The base plate 25 has multiple air inlets, which are connected to the fresh air connection port 231.

The flow equalization mesh assembly 33, disposed between the exhaust front panel 31 and the exhaust back panel 32, can evenly distribute the airflow entering the exhaust mechanism 3, avoiding airflow concentration or turbulence, and improving the stability and efficiency of the exhaust. The exhaust front panel 31 has bends at the ends near the lampshade panel 11 and the flow equalization mesh assembly 33. These bends increase the rigidity of the exhaust front panel 31, preventing deformation and ensuring long-term stability. The bottom of the exhaust back panel 32 has an oil inlet, which effectively collects grease and impurities carried out during the exhaust process, preventing oil drips into the kitchen environment.

[0061] Furthermore, such as Figure 3As shown, the flow equalization mesh assembly 33 includes a support frame 331, multiple flow equalization meshes 332 arranged sequentially, and side baffles 333 disposed on both sides of the flow equalization meshes 332.

The outer side of the support frame 331 is flush with the outer side of the side baffles 333. The flow equalization meshes 332 are disposed above the side baffles 333. Both ends of the support frame 331 are connected to the side baffles 333, and the flow equalization meshes 332 are disposed on the support frame 331. At the middle position of the support frame 331, side baffles 333 are set on both sides of the flow equalization net 332. The other end of the side baffles 333 is connected to the exhaust front plate 31. The support frame 331 is detachably connected to the exhaust back plate 32, making it easy to disassemble the support frame 331 and the exhaust back plate 32 for convenient daily cleaning and maintenance. At the same time, the support frame 331 can provide a solid support for the flow equalization net 332, preventing the flow equalization net 332 from shifting due to airflow impact or vibration, ensuring the secure fixation and stability of the flow equalization net 332, and improving the efficiency of the fume hood.

The light-blocking plates 34 are located below the flow equalization net 332, and the exhaust vent is located above the light-blocking plates 34. They can effectively block direct light, avoid glare, and improve the uniformity and comfort of lighting. The light-blocking plates 34 can also guide the oil fume airflow smoothly into the exhaust vent, prevent the oil fume from spreading, improve exhaust efficiency, and improve kitchen air quality. The support frame 331 has multiple first lamp holder components 35 on the side facing the light-blocking plate 34, and the light-blocking plate 34 is connected to the first lamp holder components 35. The exhaust front plate 31 has multiple second lamp holder components 36 on the side facing the light-blocking plate 34, and the light-blocking plate 34 is connected to the second lamp holder components 36.
