[0038] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0040] like Figures 1 to 6 As shown, this embodiment of the present disclosure provides a range hood that can illuminate the cooking area using multiple light sources 22 while preventing shadows from appearing in the cooking area. This design ensures effective lighting of the cooking area while achieving shadowless illumination, thus improving the user experience.

[0041] like Figures 1 to 6 As shown, this disclosure provides a range hood for extracting cooking fumes from a cooking area. The range hood includes a housing 10 and a lighting assembly. The housing 10 is disposed above the cooking area; the lighting assembly includes a plurality of lighting devices 20 mounted on the housing 10, the plurality of lighting devices 20 being arranged along the periphery of the cooking area, and the light emitted by the plurality of lighting devices 20 being defined as facing the cooking area.

[0042] Specifically, the range hood also includes a fan housed within the housing 10. The housing 10 also has an air inlet through which the fan draws in cooking fumes from the cooking area. The housing 10 has a mounting surface for mounting lighting components, ensuring that multiple lighting components are at the same horizontal height. The projection of the cooking area onto the horizontal plane of the mounting surface constitutes a reference area 11. Multiple lighting devices 20 arranged along the periphery of the cooking area means that multiple lighting devices 20 are arranged along the periphery of the reference area 11. Thus, any one of the lighting devices 20 can illuminate the cooking area from its oblique upper side. At least two lighting devices 20 are positioned opposite each other on either side of the reference area 11, and the light emitted by the multiple lighting devices 20 onto the cooking area at least partially overlaps.

[0043] When the user is cooking, the lighting components of the range hood can be turned on. At this time, multiple lighting components located around the cooking area can emit light from multiple directions to illuminate the cooking area. It can be seen that the range hood provided in this application can illuminate the cooking area through multiple light sources 22, and can avoid shadows in the cooking area. This design ensures effective lighting of the cooking area while achieving shadowless lighting, improving the user experience.

[0044] In practical applications, the shape and size of the cooking area can be set according to the quantity and size of cookware such as pots and pans and stoves, so that the pots and pans can be fully installed in the cooking area, thereby ensuring the lighting effect of the range hood's lighting components on the pots and pans. For example, the shape of the cooking area can be rectangular.

[0045] Optionally, the distance between the lighting component and the reference area 11 is greater than or equal to 3 cm. For example, the distance between the lighting component and the reference area 11 is 3 cm, 5 cm, 7 cm, 9 cm, or 10 cm. This increases the angle of the light illuminating the cooking area, thereby further improving the effect of the shadowless lighting of the range hood.

[0046] Optionally, the distance between the lighting component and the reference area 11 is less than or equal to 10cm. For example, the distance between the lighting component and the reference area 11 is 10cm, 9cm, 7cm, 5cm, or 3cm. This ensures the lighting effect of the lighting component on the cooking area.

[0047] like Figure 2 As shown, in some embodiments, the lighting assembly includes a left lighting device 20 and a right lighting device 20. The left lighting device 20 is mounted on the housing 10 and is located on the left side of the cooking area; the right lighting device 20 is mounted on the housing 10 and is located on the right side of the cooking area relative to the left lighting device 20.

[0048] Specifically, the left lighting device 20 being located on the left side of the cooking area means that the left lighting device 20 is installed on the mounting surface and located on the left side of the reference area 11. In this way, the left lighting device 20 can illuminate the cooking area from the upper left. Similarly, the right lighting device 20 being located on the right side of the cooking area means that the right lighting device 20 is installed on the mounting surface and located on the right side of the reference area 11. In this way, the right lighting device 20 can illuminate the cooking area from the upper right. With this arrangement, the left and right lighting devices 20 can illuminate the cooking area from the upper left and upper right respectively. The cooperation between the left and right lighting devices 20 further enhances the shadowless lighting effect of the range hood.

[0049] In some embodiments, the lighting assembly further includes a front lighting device 20 and a rear lighting device 20. The front lighting device 20 is mounted on the housing 10 and is located in front of the cooking area; the rear lighting device 20 is mounted on the housing 10 and is located behind the cooking area relative to the front lighting device 20.

[0050] Specifically, the front lighting device 20 being located at the front of the cooking area means that the front lighting device 20 is mounted on the mounting surface and located at the front of the reference area 11. In this way, the front lighting device 20 can illuminate the cooking area from the upper front. Similarly, the rear lighting device 20 being located at the rear of the cooking area means that the rear lighting device 20 is mounted on the mounting surface and located at the rear of the reference area 11. In this way, the rear lighting device 20 can illuminate the cooking area from the upper rear. With this arrangement, the front lighting device 20 and the rear lighting device 20 can illuminate the cooking area from the upper front and upper rear, respectively. The cooperation between the front lighting device 20 and the rear lighting device 20 further improves the shadowless lighting effect of the range hood.

[0051] like Figures 3 to 6 As shown, in some embodiments, the lighting device 20 includes a lamp assembly 21 and a transmissive plate 24. The lamp assembly 21 is used to emit light into the cooking area; the transmissive plate 24 is disposed between the lamp assembly 21 and the cooking area; wherein, a light-diffusing layer 241 is disposed on the side of the transmissive plate 24 facing the lamp assembly 21.

[0052] Specifically, the lighting device 20 also includes a mounting plate. A transmissive plate 24 is mounted on the mounting plate, and the luminaire assembly 21 is mounted above the mounting plate. Thus, when the luminaire assembly 21 illuminates the cooking area, the light emitted by the luminaire assembly 21 can penetrate the transmissive plate 24 and illuminate the cooking area. Because a light-diffusing layer 241 is provided on the side of the transmissive plate 24 facing the luminaire assembly 21, the light is scattered or refracted by the light-diffusing layer 241 when it passes through the transmissive plate 24, thereby transforming the point light source 22 into a surface light source 22. This arrangement further improves the lighting effect.

[0053] In practical applications, the light-diffusing layer 241 can be a light-diffusing sheet structure with a frosted finish or a light-diffusing sheet structure with fine scattering stripes.

[0054] like Figure 3 As shown, in some embodiments, the lighting assembly 21 includes a reflector 23 and a light source 22. The reflector 23 includes an inclined reflective surface; the light source 22 is used to emit light towards the reflective surface; wherein the reflective surface can reflect the light emitted by the light source 22 to the cooking area.

[0055] Specifically, the reflector 23 is positioned above the transmissive plate 24, with the light source 22 and the transmissive plate 24 located on the same side of the reflector 23. The reflector 23 has a reflective surface on the side facing the light source 22 and the transmissive plate 24. The direction of the light emitted from the light source 22 is limited to the reflector 23. Thus, the light source 22 can emit light towards the reflector 23, which then reflects the light before passing through the transmissive plate 24 and illuminating the cooking area.

[0056] Understandably, if the light emitted from the light source 22 directly penetrates the transmission plate 24 and illuminates the cooking area, bright spots will form in certain areas of the transmission plate 24 and the cooking area. Therefore, by directing the light source 22 towards the reflector 23, the light is reflected before penetrating the transmission plate 24 and illuminating the cooking area. This avoids the formation of bright spots in certain areas of the transmission plate 24 and the cooking area, improving the user experience.

[0057] like Figure 3 As shown, optionally, the end of the mounting plate facing away from the reflector 23 is provided with a mounting groove, and the light source 22 is mounted in the mounting groove. The opening of the mounting groove faces the reflector 23. In this way, the portion of the mounting groove corresponding to the transmission plate 24 can act as a light shield, thereby preventing the light from the light source 22 from directly hitting the transmission plate 24.

[0058] Optionally, the light source 22 is an LED lamp bead.

[0059] like Figures 3 to 5 As shown, in some embodiments, the tilt angle of the reflective surface is greater than or equal to a first preset angle and less than or equal to a second preset angle.

[0060] Specifically, the tilt angle of the reflective surface is greater than or equal to 1° and less than or equal to 45°. For example, the tilt angle of the reflective surface can be 1°, 10°, 20°, 30°, 40°, or 45°. This allows light to be reflected more effectively to the cooking area.

[0061] In some embodiments, the reflector 23 further includes a pivot axis about which the reflector 23 can rotate to adjust the tilt angle of the reflective surface.

[0062] Specifically, the reflector 23 is rotatably mounted on the mounting plate via a pivot axis, allowing the reflector 23 to rotate around the pivot axis. This allows the user to adjust the angle of light reflection by rotating the reflector 23, thereby adjusting the area illuminated by the light according to the size of the cooking area and the size of the cookware.

[0063] In some embodiments, the luminaire assembly 21 further includes a driving device. The driving device is drivenly connected to the reflector 23 and is used to drive the reflector 23 to rotate about a pivot axis.

[0064] Specifically, the lighting assembly 21 also includes a control device, which is electrically connected to the drive device. The user can control the rotation angle of the reflector 23 according to the control device to improve the rotation accuracy of the reflector 23.

[0065] In the above embodiments, the control device may also include a control panel or a remote control module. The user can input drive signals such as rotation angle to the control device through the control panel or remote control module, and then drive the reflector 23 to rotate through the drive device.

[0066] like Figure 2 As shown, in some embodiments, the length of the lighting device 20 is greater than or equal to the length of the cooking area and the edge corresponding to the lighting device 20; the lighting device 20 includes a plurality of lamp assemblies 21, and the plurality of lamp assemblies 21 are arranged along the length direction of the lighting device 20.

[0067] Specifically, the cooking area is configured as a rectangle, and the lighting device 20 is configured as a rectangle corresponding to the cooking area, with the lighting device 20 arranged parallel to the edge of the cooking area. In this way, the length of the lighting device 20 is greater than or equal to the length of the cooking area and its corresponding edge, and multiple lamp components 21 are arranged along the length of the lighting device 20. This allows the light emitted by the lighting device 20 to completely cover the cooking area, thereby preventing shadows from appearing in the cooking area and further improving the shadowless lighting effect.

[0068] like Figure 6 As shown, in some embodiments, the lighting device 20 further includes a one-way transparent glass 242. The one-way transparent glass 242 is attached to the side of the transmissive plate 24 opposite to the luminaire assembly 21.

[0069] Specifically, the one-way transparent glass 242 is attached to the side of the transmission plate 24 facing away from the lighting assembly 21. Thus, when the lighting assembly 21 is on, light can penetrate the transmission plate 24 and the one-way transparent glass 242 to illuminate the cooking area. When the lighting assembly 21 is off, ambient light cannot pass through the one-way transparent glass 242 to illuminate the interior of the lighting device 20. This arrangement allows the interior of the lighting device 20 to be concealed, increasing its seamlessness and maintaining the overall aesthetic harmony of the range hood.

[0070] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them.
