Description

Technical Field

[0001] This application relates to the field of kitchen fume hood technology, specifically a ceiling fume hood. Background Technology

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

[0003] In the existing technology, most of the lighting panels of fume hoods are flat, which limits the divergence angle of the light, resulting in an insufficient lighting range, easy creation of blind spots, affecting the cooking experience and user safety, and reducing user efficiency.

[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 that the existing flat-panel lighting panels limit the divergence angle of the lighting lamps, resulting in insufficient lighting range, easy creation of blind spots, and impact on cooking experience and user safety, this application provides a ceiling-mounted fume hood. Through the structure of the lighting panel, the divergence angle of the lighting lamps can be expanded, allowing the light to cover the cooking area more extensively, reducing blind spots, and improving cooking experience and user safety.

[0006] To achieve the above objectives, this application provides the following technical solution: a ceiling fume hood, comprising: A lighting device, comprising at least three lighting panels and lighting lamps mounted on the lighting panels; At least four exhaust mechanisms are installed on the outside of the lighting device, and the outside of each lighting panel is connected to an exhaust mechanism; At least four air curtain mechanisms are installed on the outside of the exhaust mechanism, and the four air curtain mechanisms form a rectangular structure. Each of the lighting panels has at least two bends, and the bends are all directed toward the corresponding ventilation mechanism.

[0007] Compared to existing technologies, by incorporating bends in the lighting panel, the illumination angle of the lights can be adjusted, expanding the light dispersion angle and allowing for wider coverage of the cooking area. This reduces blind spots, improves the cooking experience, and enhances user safety. Furthermore, by installing at least four exhaust and air curtain mechanisms, the coordinated operation of these multiple mechanisms effectively improves the efficiency of fume extraction, meets the needs of different kitchens, accommodates larger kitchens, and further purifies the kitchen air.

[0008] Preferably, the bending angle range is 130°~180°.

[0009] In this embodiment, by setting an appropriate angle, the illumination range of the lighting can be optimized to ensure that the light covers the cooking area evenly and extensively, avoiding blind spots.

[0010] Preferably, each of the exhaust mechanisms includes an exhaust frame and a flow equalization net, wherein the flow equalization net is installed inside the exhaust frame; The exhaust frame has a support plate on the side facing the lighting panel, and the lighting panel at least partially cooperates with the support plate to realize the connection between the lighting device and the exhaust mechanism. The support plate has a V-shaped structure.

[0011] In this embodiment, the support plate is used to support the lighting panel, which can enhance the connection strength between the lighting panel and the exhaust frame, provide stable support for the lighting panel, and further improve the stability and durability of the lighting device.

[0012] Preferably, the end of the lighting panel that mates with the support plate has a hook structure.

[0013] In this embodiment, the hook structure can prevent the lighting panel from loosening or falling off due to vibration or force during use, thereby improving the stability of the lighting panel.

[0014] Preferably, a plurality of lifting rods are provided between the top of the exhaust mechanism and the air curtain mechanism, and the lifting rods are arranged at intervals along the length of the fume hood; The hoisting rod has a U-shaped structure.

[0016] Preferably, each of the exhaust mechanisms further includes a UV fume purification lamp, which is installed inside the exhaust frame; The top of the exhaust frame is provided with at least one exhaust connection port, and the UV oil fume purification lamp tube is at least partially located in the exhaust connection port.

[0017] In this embodiment, the UV fume purification lamp is at least partially located in the exhaust port, which helps to guide the airflow smoothly into the exhaust port, reduce airflow resistance and energy loss, thereby improving the overall exhaust efficiency of the ceiling fume hood.

[0018] Preferably, each of the air curtain mechanisms includes an air curtain frame and at least two air curtain fans, the air curtain fans being mounted on top of the air curtain frame.

[0019] In this embodiment, after the air curtain fan is started, it quickly forms an air curtain around the fume hood to prevent oil fumes from spreading into the kitchen environment and keep the air clean.

[0020] Preferably, the air curtain frame includes an air curtain top plate, an air curtain bottom plate, and four air curtain side plates. The two sides of the four air curtain side plates are connected to each other, and the top and bottom are respectively connected to the air curtain top plate and the air curtain bottom plate, forming a rectangular structure. The air curtain fan is installed on the top plate of the air curtain.

[0021] In this embodiment, the rectangular frame structure can form a robust overall frame, enhancing the strength and stability of the air curtain mechanism.

[0022] Preferably, the air curtain base plate is divided into an air inlet plate and a light plate; one side of the air inlet plate is detachably connected to the light plate, and the other side is fixedly connected to the outermost air curtain side plate; The air inlet plate is provided with at least two rows of spaced air inlets, which are connected to the air curtain fan; One row of air inlets near the exhaust mechanism has a U-shaped structure, while the other row of air inlets has a funnel-shaped structure.

[0023] In this embodiment, air inlets of different shapes are designed according to their orientation and functional areas, which can more accurately guide and collect airflows of different directions and properties, avoid airflow interference, and improve the efficiency and effectiveness of the overall exhaust system.

[0024] Preferably, each of the air curtain mechanisms further includes an air curtain middle plate, one side of which is connected to the middle of the air curtain side plate near the exhaust mechanism, and the other side is connected to the light plate near the air inlet plate.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0031] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 5 illustrate.

[0032] This embodiment provides a ceiling-mounted fume hood, which is applied in the field of kitchen fume hood technology. Specifically, as shown in... Figures 1 to 5As shown, the device includes a lighting device 1, at least four exhaust mechanisms 2, and at least four air curtain mechanisms 3. The four exhaust mechanisms 2 are respectively installed on the outside of the lighting device 1, with the side of each exhaust mechanism 2 closest to the lighting device 1 having an inclined structure. The four air curtain mechanisms 3 are respectively installed on the outside of the exhaust mechanisms 2, forming a rectangular structure. The multiple exhaust mechanisms 2 and air curtain mechanisms 3 work together to effectively improve the efficiency of fume extraction, meet the needs of different kitchens, adapt to larger kitchens, and further purify the kitchen air. The lighting device 1 includes at least three lighting panels 11 and lighting lamps installed on the lighting panels 11. A mounting hole 112 is provided in the middle of each lighting panel 11, through which the lighting lamps are connected to the lighting panels 11. Each lighting panel 11 has at least one lighting lamp installed on it, and the outside of each lighting panel 11 is connected to an exhaust mechanism 2. Each lighting panel 11 has at least two bends 111, and the bends 111 are all oriented towards the corresponding exhaust mechanism 2. The bends 111 can adjust the illumination angle of the lighting lamp, expand the light diffusion angle of the lighting lamp, so that the light can cover the cooking area more widely, reduce lighting dead spots, improve the cooking experience and user operation safety.

[0033] Specifically, such as Figure 3 As shown, the bending angle of 111 is in the range of 130°~180°, preferably 165°. By setting an appropriate angle, the illumination range of the lighting can be optimized to ensure that the light covers the cooking area evenly and extensively, and to avoid blind spots.

[0034] Furthermore, such as Figure 3 As shown, each exhaust mechanism 2 includes an exhaust frame 21, a flow equalization net, and at least two light-blocking plates 23. The flow equalization net is installed inside the exhaust frame 21 and can evenly disperse the airflow, preventing local airflow from being too fast or too slow. The light-blocking plates 23 are located below the flow equalization net and can effectively block direct light, avoid glare, and improve the uniformity and comfort of lighting. The light-blocking plates 23 can also guide the oil fume airflow smoothly into the exhaust port, prevent the oil fume from spreading, improve exhaust efficiency, and improve kitchen air quality.

[0035] like Figure 5 As shown, the exhaust frame 21 has a support plate 22 on the side facing the lighting panel 11. The lighting panel 11 is at least partially engaged with the support plate 22, that is, the end of the lighting panel 11 facing the exhaust frame 21 is at least partially attached to the support plate 22 to realize the connection between the lighting device 1 and the exhaust mechanism 2. The support plate 22 has a V-shaped structure and is used to support the lighting panel 11. It can enhance the connection strength between the lighting panel 11 and the exhaust frame 21, provide a stable support for the lighting panel 11, and further improve the stability and durability of the lighting device 1.

[0036] The end of the lighting panel 11 that mates with the support plate 22 has a hook structure and is bent away from the support plate 22. The hook structure can prevent the lighting panel 11 from loosening or falling off due to vibration or force during use, thereby improving the stability of the lighting panel 11.

[0037] The exhaust frame 21 has an oil collection tank at its bottom, which collects the generated oil to prevent it from dripping and contaminating the stove and kitchen environment. Collecting the oil in the tank also facilitates future maintenance and cleaning. An oil drain is located below the oil collection tank, allowing for regular cleaning and drainage to prevent excessive oil accumulation and overflow.

[0038] Furthermore, such as Figure 1 , Figure 3 As shown, multiple lifting rods 4 are provided between the top of the exhaust mechanism 2 and the air curtain mechanism 3. The lifting rods 4 are arranged at intervals along the length of the fume hood. The length of the lifting rod 4 is equal to the width of the ceiling fume hood. The lifting rod 4 has a U-shaped structure, which can enhance the overall rigidity and stability of the integrated fume hood, prevent deformation, and ensure safety and durability during long-term use.

[0039] Furthermore, such as Figure 3 As shown, each exhaust unit 2 also includes a UV fume purification lamp, which is installed inside the exhaust frame 21 and positioned above the airflow equalization network. The UV fume purification lamp emits ultraviolet light to kill and decompose bacteria and harmful substances in the fumes, further purifying the kitchen air and improving the hygiene level of the kitchen environment. The top of the exhaust frame 21 has at least one exhaust connection 211, and the UV fume purification lamp is at least partially located in the exhaust connection 211. This helps guide airflow smoothly into the exhaust connection, reducing airflow resistance and energy loss, thereby improving the overall exhaust efficiency of the ceiling hood.

[0040] Furthermore, such as Figure 3 As shown, each air curtain mechanism 3 includes an air curtain frame 31 and an air curtain fan. The air curtain fan is installed on the top of the air curtain frame 31. After the air curtain fan is started, it quickly forms an air curtain around the fume hood to prevent oil fumes from spreading into the kitchen environment and keep the air clean. The top of the air curtain frame 31 is provided with at least two fresh air inlets 311. The air curtain fan is installed in the fresh air inlets 311. The fresh air inlets 311 can effectively balance the air pressure inside and outside the fume hood, ensuring that the air curtain fan can work stably and efficiently.

[0041] Specifically, such as Figure 3 , Figure 4As shown, the air curtain frame 31 includes an air curtain top plate 312, an air curtain bottom plate 313, and four air curtain side plates 314. The two sides of the four air curtain side plates 314 are connected to each other, and the top and bottom of the air curtain side plates 314 are connected to the air curtain top plate 312 and the air curtain bottom plate 313, respectively, forming a rectangular structure. The rectangular frame structure can form a sturdy overall frame, enhancing the strength and stability of the air curtain mechanism 3. The exhaust frame 21 is connected to the top and bottom of the air curtain side plate 314 facing it. The air curtain fan is set on the air curtain top plate 312, so that fresh air enters the interior of the air curtain mechanism 3 evenly from the top, improving the air curtain mechanism 3's airflow isolation effect.

[0042] Among them, such as Figure 3 , Figure 4 As shown, the air curtain base plate 313 is divided into an air inlet plate 3131 and a light plate 3132. One side of the air inlet plate 3131 is detachably connected to the light plate 3132, and the other side is fixedly connected to the outermost air curtain side plate 314. Both the side of the air inlet plate 3131 connected to the light plate 3132 and the side of the air curtain side plate 314 are provided with L-shaped bends. The side of the light plate 3132 connected to the air inlet plate 3131 is also provided with L-shaped bends. The bending direction is towards the exhaust mechanism 2. The L-shaped bends of the air inlet plate 3131 are set on the L-shaped bends of the light plate 3132, which can increase the connection contact area between the air inlet plate 3131 and the light plate 3132 and enhance the connection strength between the two.

[0043] like Figure 3 , Figure 4 As shown, the air inlet plate 3131 has at least two rows of spaced air inlets 31311. The air inlets 31311 are connected to the air curtain fan, allowing fresh air to enter through the air curtain fan and flow evenly into the air curtain mechanism 3 from the air inlets 31311, forming a stable airflow barrier. One row of air inlets 31311 near the exhaust mechanism 2 has a U-shaped structure, while the other row has a funnel-shaped structure. The U-shaped air inlets 31311 face the lighting device 1, effectively capturing and guiding the heat and airflow generated near the lighting device 1. The funnel-shaped air inlets 31311 are vertically arranged, effectively blocking the oil fumes and exhaust gases around the stove, improving exhaust efficiency, and reducing the diffusion of oil fumes. The different shapes of the air inlets 31311 are designed according to their orientation and functional areas, enabling more precise guidance and collection of airflows of different directions and properties, avoiding airflow interference, and improving the efficiency and effect of the overall exhaust system.

[0044] Each air curtain mechanism 3 includes an air curtain intermediate plate 315. One side of the air curtain intermediate plate 315 is connected to the middle of the air curtain side plate 314 near the exhaust mechanism 2, and the other side of the air curtain intermediate plate 315 is connected to the light plate 3132 near the air inlet plate 3131. The air curtain intermediate plate 315 has a bend 111, with the bend 111 facing the air inlet plate 3131, meaning the top of the air curtain intermediate plate 315 is inclined towards the air inlet plate 3131. The light plate 3132 has at least two lights, and the air curtain intermediate plate 315 is positioned above the lights, covering them. The air curtain intermediate plate 315 serves to separate the air inlet 31311 and the fresh air connection 311, ensuring that the lights are not affected by airflow or other factors. Furthermore, the lights in the air curtain mechanism 3 can increase the lighting range around the stove, reduce the angle of light, and allow the light to cover the cooking area more extensively, improving the cooking experience and user safety.

[0045] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
