DETAILED DESCRIPTION

[0031] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0033] The embodiment of the present application provides a range hood that can extract fumes generated during cooking, reduce grease, smoke and odor in the kitchen air, and thus keep the kitchen environment clean and healthy.

[0034] See Figures 1-8 The range hood 10 provided in this application includes a range hood body 100, a fume hood 200, and a lighting lamp 300. The fume hood 200 is connected to an end of the range hood body 100 and has a fume inlet 201 and an air curtain outlet 202. The fume hood 200 is provided with a light-transmitting plate 210, a first side panel 220, and a second side panel 230. The first side panel 220 and the second side panel 230 are disposed opposite each other. The fume inlet 201, the air curtain outlet 202, and the light-transmitting plate 210 are all located on the same side of the fume hood 200 and opposite the range hood body 100. The fume inlet 201 is close to the first side panel 220, and the light-transmitting plate 210 and the air curtain outlet 202 are close to the second side panel 230. The lighting lamp 300 is mounted on the side of the light-transmitting plate 210 facing the range hood body 100 and is located between the air curtain outlet 202 and the second side panel 230. In this way, compared with the range hoods in the related art, the lighting lamp 300 of the range hood 10 of the present application is installed on the side of the light-transmitting plate 210 facing the range hood body 100, so that the lighting lamp 300 is stored inside the range hood 10, thereby helping to reduce the risk of the lighting lamp 300 directly contacting the oil smoke, and thus making the lighting lamp 300 less likely to be contaminated.

[0035] In addition, the lighting lamp 300 is housed inside the range hood 10, preventing oil, water vapor or food residue splashed during cooking from directly contacting the lighting lamp 300, thereby helping to extend the service life of the lighting lamp 300 and also helping to reduce the need for cleaning and maintenance of the lighting lamp 300.

[0036] Moreover, when oil smoke approaches the light-transmitting plate 210 , the air flowing out from the air curtain outlet 202 can drive the oil smoke away from the light-transmitting plate 210 and make the oil smoke flow toward the smoke inlet 201 , thereby helping to reduce the risk of oil smoke contaminating the light-transmitting plate 210 .

[0037] In some embodiments, the range hood body 100 has a smoke outlet, which can be located at the top of the range hood 10. The range hood 10 can connect the smoke outlet to the outdoor environment through a smoke exhaust duct. The range hood 10 can also include a first fan, which is located inside the range hood body 100. When the first fan is in operation, it can draw in oil smoke, steam, etc. through the smoke inlet 201, and exhaust them from the smoke outlet, and finally exhaust them to the outside through the smoke exhaust duct.

[0038] In some embodiments, the fume hood 200 further includes an air curtain outlet, which may be located on the side of the fume hood 200. The range hood 10 may further include a second fan, which may drive air to flow in from the air curtain outlet and out from the air curtain outlet 202.

[0039] In some embodiments, the smoke inlet and the smoke outlet may form a smoke exhaust channel, the air curtain outlet and the air curtain outlet 202 may form an air guide channel, and the smoke exhaust channel and the air guide channel are independent of each other.

[0040] When the range hood 10 is mounted on a wall, the first side panel 220 may be disposed opposite to the wall.

[0041] In some embodiments, the smoke hood 200 is further provided with a bracket 240, which is connected to the light-transmitting plate 210. The light-transmitting plate 210 and the bracket 240 together enclose a confined space 250. The illuminating lamp 300 is located in the confined space 250 and abuts between the light-transmitting plate 210 and the bracket 240. In this way, the confined space 250 formed by the bracket 240 and the light-transmitting plate 210 can provide a stable mounting platform for the illuminating lamp 300, so that the illuminating lamp 300 is clamped between the bracket 240 and the light-transmitting plate 210, thereby maintaining a fixed position during operation, thereby helping to reduce the risk of displacement of the illuminating lamp 300 due to vibration.

[0042] In some embodiments, the bracket 240 includes a first connecting portion 241 and a limiting portion 242 connected to each other, the first connecting portion 241 is connected to the light-transmitting plate 210, the limiting portion 242 and the light-transmitting plate 210 together enclose a limiting space 250, and the lighting lamp 300 is located in the limiting space 250 and abuts between the light-transmitting plate 210 and the bracket 240.

[0043] In this way, the lighting lamp 300 does not need to be fixed with screws, the assembly process is relatively simple, the installation efficiency of the lighting lamp 300 can be further improved, and it is also convenient for future maintenance and replacement.

[0044] In addition, the range hood 10 of the present application does not need to have slots for installing the lighting lamp 300 on the smoke collecting hood, so that the smoke collecting hood has better structural strength.

[0045] In some embodiments, the bracket 240 further includes an elastic pressing portion 243 . The elastic pressing portion 243 is connected to the limiting portion 242 and presses the lighting lamp 300 toward the light-transmitting plate 210 .

[0046] Among them, the elastic pressing portion 243 can be a spring. When the lighting lamp 300 is installed in place, the elastic pressing portion 243 provides a downward pre-tightening force to press the lighting lamp 300 against the light-transmitting plate 210, so that the light-emitting surface of the lighting lamp 300 is always close to the light-transmitting plate 210.

[0047] In this way, the elastic pressing portion 243 provides a downward pre-tightening force, so that the lighting lamp 300 and the light-transmitting plate 210 are tightly combined, so that the lighting lamp 300 remains in a fixed position during operation, thereby helping to reduce the risk of displacement of the lighting lamp 300 due to vibration.

[0048] At the same time, pressing the lighting lamp 300 against the light-transmitting plate 210 can utilize the transparent characteristics of the light-transmitting plate 210 to reduce light scattering and loss of the lighting lamp 300, so that the light can be more concentrated and evenly transmitted through the light-transmitting plate 210 to illuminate the cooking area, thereby improving lighting efficiency and effect and providing the cook with a clearer field of vision.

[0049] In some embodiments, the bracket 240 is further provided with a second connecting portion 245 , and the second connecting portion 245 is connected to the smoke collecting hood 200 and the limiting portion 242 .

[0050] In this way, the bracket 240 can not only cooperate with the light-transmitting plate 210 to limit the lighting lamp 300, but can also be connected to the smoke hood 200 through the second connecting part 245, so that the light-transmitting plate 210 can be installed on the smoke hood 200, thereby making the bracket 240 have multiple functions, which in turn helps to reduce the connecting parts of the range hood 10.

[0051] In some embodiments, the second connection portion 245 and the smoke hood 200 may be connected by a threaded connection or a snap-fit ​​connection.

[0052] For example, the second connection portion 245 may be provided with a through hole, and the smoke hood 200 may be provided with a threaded through hole. The second connection portion 245 is threadedly connected to the smoke hood 200 by screws, thereby fixing the bracket 240 and the light-transmitting plate 210 on the smoke hood 200 .

[0053] In some embodiments, the bracket 240 is a thermally conductive bracket, and the lighting lamp 300 is attached to the bracket 240. The bracket 240 can be made of a metal material, such as a copper bracket or an aluminum bracket, or a copper alloy bracket or an aluminum alloy bracket; or the thermally conductive bracket can be a graphene bracket.

[0054] Since the lighting lamp 300 is prone to generate significant heat during the continuous power-on and lighting process, by adopting a heat-conducting bracket and attaching the lighting lamp 300 to the heat-conducting bracket, the heat generated by the lighting lamp 300 can be quickly transferred to the bracket 240, reducing the heat accumulation of the lighting lamp 300 itself, helping to alleviate the high temperature state accumulated by the lighting lamp 300 due to long-term operation, thereby protecting the lamp beads 320 in the lighting lamp 300 from overheating damage, extending the service life of the lighting lamp 300, and improving the safety performance of the lighting lamp 300.

[0055] In some embodiments, the bracket can be set near the air curtain outlet 202. When the heat of the lighting lamp 300 is transferred to the vicinity of the bracket, it can be blown out of the range hood 10 along with the air flow of the air curtain, so that the heat of the lighting lamp 300 can be quickly dissipated.

[0056] In some embodiments, the lighting lamp 300 may be an LED lamp, a halogen lamp, a fluorescent lamp, or the like.

[0057] In some embodiments, the lighting lamp 300 is arranged in a long strip shape, and the lighting lamp 300 includes a lamp housing 310 and a lamp bead 320. The lamp housing 310 is provided with a lamp bead installation cavity 311 and an insertion port 312. The insertion port 312 is connected to the lamp bead installation cavity 311. The insertion port 312 is used for allowing the lamp bead 320 to be placed into the lamp bead installation cavity 311 along the length direction of the lamp housing 310.

[0058] By configuring the lamp 300 in a strip shape, it can completely extend horizontally through the front of the light-transmitting plate 210, thus expanding the illumination area. This also reduces the surface area of ​​the lamp 300, thereby reducing the likelihood of oil and dirt contact, further enhancing the lamp's oil and dirt resistance.

[0059] In addition, the lamp bead 320 can be directly inserted from the insertion port 312 and then be positioned in the lamp bead installation cavity 311 in the lamp housing 310 , making the installation of the lighting lamp 300 more convenient.

[0060] In some embodiments, the lamp housing 310 may include a first lamp housing 330 and a second lamp housing 340 . The first lamp housing 330 and the second lamp housing 340 together enclose a lamp bead installation cavity 311 . The first lamp housing 330 and the second lamp housing 340 are integrally formed.

[0061] The first lamp housing 330 and the second lamp housing 340 can be processed and produced using an integral extrusion molding process, thereby achieving integral molding.

[0062] Thus, since the first lamp housing 330 and the second lamp housing 340 are integrally formed, the first lamp housing 330 and the second lamp housing 340 do not need to be connected using an additional adhesive, thereby avoiding the phenomenon of shadows between the first lamp housing 330 and the second lamp housing 340.

[0063] In addition, since the first lamp housing 330 and the second lamp housing 340 are integrally formed, the first lamp housing 330 and the second lamp housing 340 do not require multiple processes such as bonding and curing required in traditional manufacturing, which simplifies the production and assembly process of the lamp housing 310, helps shorten the production cycle of the lamp housing 310, and thus improves the production efficiency of the lamp housing 310.

[0064] In some embodiments, the first lamp housing 330 and the second lamp housing 340 may be transparent.

[0065] In this way, light directly passes through the transparent lamp housing 310, so that the light emitted by the lamp beads 320 can directly illuminate the area that needs to be illuminated, thereby helping to reduce light energy waste and improve lighting efficiency and brightness.

[0066] In addition, the transparent lamp housing 310 also allows users to visually check the condition of the lamp beads 320 inside the lighting lamp 300, such as whether the lamp beads 320 are emitting light normally, the dust accumulation, etc., which is conducive to timely cleaning and maintenance or troubleshooting, thereby extending the service life of the lighting lamp 300.

[0067] In some embodiments, there are multiple air curtain outlets 202 , and the multiple air curtain outlets 202 are arranged in sequence along the length direction of the lighting lamp 300 .

[0068] Since the lighting lamp 300 of the present application is configured in a long strip shape, by arranging a plurality of air curtain outlets 202 in sequence along the length direction of the lighting lamp 300 , the oil smoke can be intercepted as much as possible, so that the lighting area is not exposed to the oil smoke.

[0069] In some embodiments, the lighting lamp 300 has a light emitting surface 350 , and a diffuse reflection structure is provided on a side of the light-transmitting plate 210 facing the lighting lamp 300 , and the diffuse reflection structure abuts against the light emitting surface 350 .

[0070] The diffuse reflection structure may be formed by performing special treatment (such as frosting treatment, pickling and etching treatment) on the light-transmitting plate 210 .

[0071] Alternatively, the diffuse reflection structure may be a layer of silk-screened semi-transparent ink, a semi-transparent film, etc. added to the light-transmitting plate 210 .

[0072] In this way, a diffuse reflection structure is provided on the side of the light-transmitting plate 210 facing the illuminating lamp 300 , so that the light of the illuminating lamp 300 can be more evenly dispersed at the diffuse reflection structure.

[0073] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed across multiple network units. Some or all of the modules may be selected based on actual needs to achieve the objectives of this embodiment.
