[0002] A range hood is a kitchen appliance used to purify the kitchen environment. Installed above the stove, it quickly removes cooking fumes and harmful oil fumes from the stove, venting them outdoors. It also condenses and collects these fumes, reducing pollution, purifying the air, and providing safety features such as protection against toxic substances and explosions. The range hood uses a motor to rotate a high-speed impeller, creating a negative pressure zone above the stove that draws in cooking fumes for purification before expelling them.

[0003] In related technologies, to illuminate the stove area below the range hood's top panel, a mounting groove is typically provided on the top panel. This groove connects to the smoke collection chamber, and the lighting fixture extends directly into and connects to the groove. However, this makes the lighting fixture susceptible to contamination from the oil fumes within the chamber. Therefore, there is an urgent need to design a new installation method for the lighting components. Utility Model Content

[0019] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0020] The following is for reference. Figures 1-12 The range hood 100 according to an embodiment of the present utility model can provide protection for the lighting component 20 inside the cavity 11 through the protective cover 30, and can also prevent oil stains formed by oil fumes from seeping into the outside from the gaps between the lighting component 20 and the mounting port 121.

[0021] Combination Figures 1-12As shown, the range hood 100 according to the first aspect of this utility model includes a range hood body 10, a lighting component 20, and a protective cover 30. The range hood body 10, as the main load-bearing structural component of the external outline of the range hood 100, protects the internal structures and provides sound insulation, reducing noise generated during operation. The lighting component 20 illuminates the stove area, improving visibility for the user. The protective cover 30 provides structural protection and enclosure for the lighting component 20.

[0022] Specifically, a cavity 11 is formed inside the main body 10 of the range hood. The main body 10 of the range hood includes a top plate 12, and the top plate 12 has an installation port 121. The lighting component 20 is disposed in the installation port 121, and part of the lighting component 20 extends into the cavity 11 through the installation port 121. The protective cover 30 is located in the cavity 11 and is connected to the top plate 12. The protective cover 30 corresponds to the installation port 121 and covers the lighting component 20 and the installation port 121.

[0023] Specifically, the area below the top plate 12 is the stove area, which can prevent the oil fumes generated during cooking from spreading upwards. The top plate 12 is provided with an installation opening 121 that opens towards the stove side. When installing the lighting component 20, after the lighting component 20 is installed into the installation opening 121, the lighting surface of the lighting component 20 is set downwards, so that it can illuminate the stove area when the user is cooking. In addition, for aesthetic purposes, the lighting surface of the lighting component 20 is flush with the lower surface of the top plate 12, and the other parts of the lighting component 20 enter the cavity 11 through the installation opening 121.

[0024] Furthermore, the protective cover 30 inside the cavity 11 is tightly connected to the inner side of the top plate 12, and the protective cover 30 corresponds to the mounting port 121 on the top plate 12. The protective cover 30 covers part of the lighting component 20 extending into the cavity 11 and the mounting port 121. This can block the oil fumes inside the cavity 11 or on the top plate 12, preventing the oil stains formed by the oil fumes from dripping or flowing to the lighting component 20 and the mounting port 121. This effectively prevents the risk of damage to the lighting component 20 caused by oil fumes and the risk of oil stains formed by oil fumes seeping to the outside of the top plate 12 through the gap between the lighting component 20 and the mounting port 121. This improves the oil-proof effect of the lighting component 20 and the cleanliness of the exterior of the range hood 100 at the mounting port 121, thus enhancing the design rationality of the range hood 100.

[0025] Therefore, by setting up the range hood 100, the protective cover 30 can form a protective effect on the lighting component 20 inside the cavity 11, thereby effectively preventing the part of the lighting component 20 placed inside the cavity 11 from being contaminated by oil fumes, and also preventing the oil stains formed by oil fumes from seeping into the outside from the gaps between the lighting component 20 and the mounting port 121, thereby ensuring the cleanliness of the exterior of the range hood 100 at the lighting component 20.

[0026] According to some optional embodiments of the present invention, combined with Figures 1-12 As shown, the protective cover 30 includes a partition 31, which divides the cavity 11 into an electrical control cavity 311 and a smoke collection cavity 312 in the front-to-back direction. The lighting assembly 20 is selectively disposed in the electrical control cavity 311 or the smoke collection cavity 312.

[0027] Specifically, along the front-to-back direction of the range hood 100, the partition 31 of the protective cover 30 can divide the cavity 11 into an electronic control cavity 311 and a smoke collection cavity 312 located behind the electronic control cavity 311. The smoke collection cavity 312 is mainly used to quickly collect and gather the oil fumes that diffuse during cooking in the kitchen, reduce the escape of oil fumes from the stove area, and prevent oil fumes from polluting the kitchen environment and walls. The electronic control cavity 311 can be used to install and accommodate the relevant components of the range hood 100.

[0028] Furthermore, the lighting component 20 can be selectively located in the electrical control cavity 311 or the smoke collection cavity 312. Since the electrical control cavity 311 and the smoke collection cavity 312 are separated by the partition 31, when the lighting component 20 is located in the electrical control cavity 311, the oil fumes in the smoke collection cavity 312 are blocked by the partition 31 and cannot flow to the lighting component 20, thus effectively preventing the risk of oil fume contamination of the lighting component 20. When the lighting component 20 is located in the smoke collection cavity 312, since the smoke collection cavity 312 is located behind the electrical control cavity 311, compared to the electrical control cavity 311, the lighting component 20, under the protection of the protective cover 30, is located in a region closer to the center on the top plate 12. This allows for a more symmetrical light distribution in the stove area below the top plate 12, enabling the lighting component 20 to provide a more uniform top lighting effect to the stove area, thereby helping to reduce shadows and uneven lighting, and improving the user's visual comfort.

[0029] Alternatively, the electrical control cavity 311 can be used to provide installation space for an air curtain device, which is a functional structure that optimizes the smoke collection and exhaust effect by blowing out airflow to form an airflow barrier, preventing the spread of oil fumes and guiding them to be efficiently sucked into the exhaust port of the range hood 100, thereby improving the cleanliness of the kitchen environment.

[0030] Specifically, in combination Figures 1-12As shown, the protective cover 30 also includes a first flange 32, which is connected to the upper edge of the partition 31; the range hood 100 also includes an air collection box 40, which is located above the main body 10 of the range hood, and an exhaust fan 41 is provided inside the air collection box 40; wherein, the first flange 32 supports the air collection box 40.

[0031] Understandably, the first flange 32 of the protective cover 30 is connected to the upper edge of the partition 31, and the first flange 32 supports the air collection box 40. This allows the protective cover 30 to not only protect the lighting component 20, but also establish a connection between the air collection box 40, the protective cover 30 and the top plate 12, thereby increasing the force support path of the top plate 12 to the air collection box 40 and effectively improving the support stability of the range hood 100 to the air collection box 40.

[0032] Alternatively, combined Figure 3 , Figure 9 and Figure 12 As shown, the first flange 32 is laminated and connected to the lower edge of the air collection box 40, which allows the first flange 32 and the lower edge of the air collection box 40 to form a surface-to-surface contact connection. This increases the contact area between the two, thereby enhancing the connection strength, stress uniformity and load-bearing capacity between the protective cover 30 and the air collection box 40, effectively improving the connection reliability and overall structural stability of the two.

[0033] In addition, the air collection box 40 is mainly used to increase the suction and holding space for oil fumes, improve the smoke collection effect, and guide the oil fume airflow to flow smoothly inside itself; the air collection box 40 is equipped with an exhaust fan 41, and the air collection box 40 can provide installation and holding space for the exhaust fan 41. The exhaust fan 41 can create a negative pressure environment at the air inlet connected to the air collection box 40, thereby using the air pressure difference to draw the oil fumes generated during cooking from above the stove into the air collection box 40, thus successfully achieving the effect of the range hood 100 sucking out the oil fumes.

[0034] Furthermore, combined Figure 2 , Figure 4 , Figure 8 , Figure 10 and Figure 11 As shown, a cavity 122 is formed on the lower surface of the top plate 12, and the top surface of the cavity 122 protrudes into the cavity 11.

[0035] Understandably, the lower surface of the top plate 12 forms a concave cavity 122 that protrudes into the cavity 11. This can, on the one hand, collect and gather the rising fumes, thereby improving the fume extraction efficiency; on the other hand, it can also increase the space above the stove area of ​​the range hood 100, which can improve the user's field of vision and thus enhance the user experience.

[0036] Furthermore, the partition 31 can be selectively disposed on the top surface of the cavity 122 or the bottom surface of the electrical control cavity 311, so that the partition 31 can be stably supported by the top surface of the cavity 122 or the bottom surface of the electrical control cavity 311, thereby ensuring the positional stability of the partition 31.

[0037] For example, when the lighting component 20 is located inside the smoke collection chamber 312, the partition 31 can be set on the top surface of the recess 122. The top surface of the recess 122 is a large surface, which can provide a stable force support for the partition 31, avoiding the risk of the partition 31 becoming weak under stress, and making the installation simpler and more reliable. For example, when the lighting component 20 is located inside the electrical control chamber 311, the partition 31 can be set on the bottom surface of the electrical control chamber 311. The bottom surface of the electrical control chamber 311 is a large surface, which can provide a stable force support for the partition 31, avoiding the risk of the partition 31 becoming weak under stress, and making the installation more convenient.

[0038] Specifically, in combination Figure 5 and Figure 11 As shown, the mounting port 121 is formed on the top surface of the cavity 122, and the mounting port 121 is located in the smoke collection cavity 312.

[0039] In other words, the top surface of the recess 122 forms an installation opening 121, which is located in the smoke collection chamber 312. The top surface of the recess 122 is a large surface, and the top surface of the recess 122 corresponds to the stove area below the top plate 12. Since the installation opening 121 is located on the top surface of the recess 122, it is convenient for the lighting component 20 at the installation opening 121 to illuminate the stove area more evenly, effectively improving the accuracy and uniformity of the illumination range of the lighting component 20, thereby enhancing the user's visual comfort. It can also effectively prevent the user from directly observing the lighting component 20 at the installation opening 121 on the recess 122, thereby improving the anti-glare effect of the lighting component 20 and improving the rationality of the arrangement of the installation opening 121.

[0040] Alternatively, combined Figure 3 , Figure 6 , Figure 9 and Figure 12 As shown, the top plate 12 has an oil-blocking edge 123 extending toward the interior of the cavity 11 at the edge surrounding the mounting opening 121.

[0041] As arranged as described above, the oil stains formed by the fumes flowing from the cavity 11 or the top plate 12 to the edge of the mounting port 121 can be blocked by the oil-blocking edge 123, preventing the oil stains formed by the fumes from flowing along the edge of the mounting port 121 to the surface of the lighting component 20 or the outside of the top plate 12 of the range hood 100, thereby ensuring the oil-blocking effect of the range hood 100 at the mounting port 121 and improving the cleanliness of the exterior of the range hood 100.

[0042] Alternatively, combine Figures 1-12 As shown, the lower edge of the protective cover 30 is provided with a second flange 33, which is stacked and connected to the top plate 12.

[0043] The second flange 33 is laminated and connected to the inner side of the top plate 12, which allows the second flange 33 and the inner side of the top plate 12 to form a surface-to-surface contact connection. This increases the contact area between the two, thereby enhancing the connection strength, stress uniformity and load-bearing capacity between the protective cover 30 and the top plate 12, and effectively improving the connection reliability and overall structural stability of the two.

[0044] Specifically, in combination Figure 2 and Figure 3 As shown, the mounting port 121 is formed on the bottom surface of the electrical control cavity 311.

[0045] It is understandable that the bottom surface of the electrical control cavity 311 has an installation port 121. The bottom surface of the electrical control cavity 311 is a large surface, and the bottom surface of the electrical control cavity 311 faces the stove area below the top plate 12. Since the installation port 121 is located on the bottom surface of the electrical control cavity 311, it is convenient for the lighting component 20 at the installation port 121 to smoothly illuminate the stove area, effectively ensuring the lighting requirements of the stove area and improving the user's visual clarity in a dim environment. Since the lighting component 20 is located in the electrical control cavity 311, it can also relatively increase the space ratio of the smoke collection cavity 312, thereby increasing the oil fume holding space of the smoke collection cavity 312, improving the oil fume collection effect of the range hood 100, and thus improving the rationality of the arrangement of the installation port 121.

[0046] Furthermore, combined Figure 8 and Figure 9 As shown, mounting port 121 is formed on the top surface of cavity 122, and mounting port 121 is located in electrical control cavity 311.

[0047] In other words, the top surface of the recess 122 forms an installation port 121, which is located in the electrical control cavity 311. At this time, the partition 31 is set on the top surface of the recess 122. The top surface of the recess 122 is a large surface, and the top surface of the recess 122 corresponds to the stove area below the top plate 12. Since the installation port 121 is set on the top surface of the recess 122, on the one hand, the lighting component 20 at the installation port 121 can more evenly illuminate the stove area, effectively improving the accuracy and uniformity of the illumination range of the lighting component 20, thereby improving the user's visual comfort; on the other hand, it can effectively prevent the user from directly observing the lighting component 20 at the installation port 121 on the recess 122, thereby improving the anti-glare effect of the lighting component 20, and thus improving the rationality of the arrangement of the installation port 121.

[0048] Specifically, in combination Figure 11 and Figure 12 As shown, a cavity 122 is formed on the lower surface of the top plate 12. The top surface of the cavity 122 protrudes into the cavity 11. A connecting plate 50 is provided between the cavity 122 and the electrical control cavity 311. A partition plate 31 is provided on the connecting plate 50.

[0049] Understandably, the lower surface of the top plate 12 forms a concave cavity 122 that protrudes into the cavity 11. This can, on the one hand, collect and gather the rising fumes, thereby improving the fume extraction efficiency; on the other hand, it can also increase the space above the stove area of ​​the range hood 100, which can improve the user's field of vision and thus enhance the user experience.

[0050] Furthermore, since the lower surface of the top plate 12 protrudes into the cavity 11 to form a recess 122, the top surface of the recess 122 is higher than the bottom surface of the electrical control cavity 311. A connecting plate 50 is provided between the recess 122 and the electrical control cavity 311. The connecting plate 50 extends upward from front to back at an angle, and the mounting opening 121 is formed on the connecting plate 50. In this way, on the one hand, it is convenient for the connecting plate 50 to establish a connection relationship with the top surface of the recess 122 and the bottom surface of the electrical control cavity 311 respectively. On the other hand, since the lighting component 20 is set separately on the connecting plate 50, the lighting component 20 does not need to occupy the space of the electrical control cavity 311, thereby reducing the size of the electrical control cavity 311 and improving the structural compactness.

[0051] Alternatively, the top surface of the cavity 122 extends downward from front to back, while the connecting plate 50 extends upward from front to back. The lighting component 20 is mounted on the connecting plate 50. This prevents the oil stains formed by the oil fumes on the top surface of the cavity 122 from accumulating along the top surface of the cavity 122 to the mounting port 121 or the lighting component 20 under the action of gravity, thereby effectively preventing the oil stains formed by the oil fumes from contaminating the mounting port 121 or the lighting component 20.
