[0002] The function of the range hood is to discharge the oil smoke generated during the cooking process to the outside, purify the kitchen air environment, and reduce the harm of oil smoke to the human body. It is widely used in life. There are many types of range hoods, including side-suction range hoods, island-type range hoods, 7-shaped range hoods, etc. The range hood is generally equipped with a lighting lamp, which is used to illuminate the cooking space below it, so that the cook can more clearly observe the color and other characteristics of the ingredients, improving the cooking experience.

[0003] The lighting lamp on the range hood in the related art is usually installed inside the smoke hood and arranged below the fan. In this way, the oil stains generated in the environment where the lighting lamp is located are likely to fall onto the top surface of the lighting lamp. The oil stains flow along the top surface of the lighting lamp and penetrate outward through the mounting hole of the lighting lamp on the smoke hood to the outer surface of the smoke hood, thereby causing oil seepage and oil dripping defects. In addition, the oil stains will flow into the interior of the lighting lamp through the periphery of the lighting lamp, causing damage to the electrical components inside the lighting lamp. Based on this, it is proposed to add a protective shell to the top surface of the lighting lamp to block the oil stains. However, this will increase the additional material cost and assembly cost.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0038] See also Figure 1 and Figure 2 , Figure 1 A structural diagram of a range hood without a back plate according to an embodiment of the present application is shown. Figure 2 Shows Figure 1 An enlarged structural diagram at A. A range hood provided in one embodiment of the present application includes but is not limited to a side suction range hood, a 7-shaped range hood, a top suction range hood, etc. The range hood includes a lighting lamp 10 and a fume collecting hood 20, and the lighting lamp 10 is mounted on the fume collecting hood 20.

[0039] See also Figures 2 to 4 , Figure 3 A schematic structural diagram of a lighting lamp 10 for a range hood according to an embodiment of the present application is shown. Figure 4 Shows Figure 3 The exploded structural diagram of the structure shown. In some embodiments, the lighting lamp 10 includes a housing 11 and an oil guide member 12. The housing 11 includes an upper housing 112 with a downward opening and a lower housing 111 covering the opening. The oil guide member 12 is located inside the smoke hood 20 and is arranged above the connection between the upper housing 112 and the lower housing 111. The oil guide member 12 is circumferentially arranged around the outer wall of the upper housing 112 and cooperates with the outer wall of the upper housing 112 to form an oil guide groove 13. The oil guide member 12 is provided with an oil outlet 120 connected to the oil guide groove 13.

[0040] During use of the above-mentioned range hood and its lighting lamp 10, the oil dirt that falls from the smoke hood 20 onto the top surface of the upper shell 112 and can slide to the bottom of the upper shell 112 is introduced into the oil guide groove 13 and guided to the oil outlet 120 along the oil guide groove 13, so that most of the oil dirt on the top surface of the upper shell 112 can be guided to the oil outlet 120 and discharged from the oil outlet 120. In this way, it is possible to effectively prevent the oil dirt from flowing to the mounting hole 212 of the lighting lamp 10 on the smoke hood 20 to cause leakage and oil dripping defects, and it is also possible to effectively prevent the oil dirt from flowing to the connection between the upper shell 112 and the lower shell 111 and entering the interior of the shell 11 to cause damage to the electrical components. At the same time, since there is no need to add a protective shell on the top surface of the shell 11, the cost is greatly reduced and it is more convenient to assemble.

[0041] It should be noted that the illuminating lamp 10 further includes a light emitting element integrated in the housing 11, a circuit board electrically connected to the light emitting element, and a power supply or plug electrically connected to the circuit board. The light emitting element includes but is not limited to an LED lamp, a light emitting chip, and the like.

[0042] As a specific example, when the range hood is a 7-shaped range hood, the lighting lamp 10 is specifically installed on the smoke collecting plate 211 of the smoke collecting hood 20. Specifically, the smoke collecting hood 20 also includes a back panel, which is used to be installed on the wall, and is hidden in the figure. Among them, the smoke collecting plate 211 is, for example, arranged at an angle with the back panel. The housing 11 is arranged on the smoke collecting plate 211. The smoke collecting plate 211 can not only collect smoke, so that the oil smoke is better sucked into the inside of the smoke collecting hood 20, but also because the lighting lamp 10 is installed and faces the stove surface, a better lighting effect can be achieved.

[0043] In some embodiments, the oil outlet 120 can be adjusted and set at any position of the oil guide member 12 according to actual needs, as long as the oil in the oil guide groove 13 can be discharged in a centralized manner. Specifically, the housing 11 and the oil guide member 12 thereon are arranged to tilt downward from front to back, and the oil outlet 120 is formed at the rear of the oil guide member 12, so that the oil inside the oil guide groove 13 flows to the oil outlet 120 under the action of its own gravity, which can achieve the discharge of most of the oil inside, better prevent oil leakage and oil dripping defects, and effectively prevent the oil from flowing to the connection between the upper housing 112 and the lower housing 111 and entering the interior of the housing 11, thereby causing damage to the electrical components. In addition, the oil discharged from the oil outlet 120 enters the interior of the smoke hood 20, flows along the inner wall of the smoke hood 20 to the oil cup, and is collected and processed by the oil cup.

[0044] See also Figures 2 to 4 In one embodiment, the wall of the oil outlet 120 is provided with a drainage portion 1201 extending in a direction away from the housing 11. In this way, under the drainage effect of the drainage portion 1201, the oil inside the oil guide groove 13 can be discharged outward through the oil outlet 120, and can flow more to the area of ​​the inner wall of the smoke hood 20 away from the housing 11, which can effectively prevent the oil from flowing to the mounting hole 212 of the lighting lamp 10 on the smoke hood 20 to cause leakage and oil dripping defects, and can also effectively prevent the oil from flowing to the connection between the upper housing 112 and the lower housing 111 and entering the interior of the housing 11, thereby causing damage to electrical components.

[0045] See also Figures 4 to 7 In some embodiments, the lower shell 111 is connected to the smoke collecting hood 20, and the upper shell 112 is located inside the smoke collecting hood 20. The lower shell 111 is specifically provided on the smoke collecting plate 211, and the outer surface of the lower shell 111 is, for example, flush with the outer surface of the smoke collecting plate 211 to improve the appearance quality.

[0046] See also Figures 5 to 8 , wherein the lower shell 111 is provided with a first protrusion 1111 circumferentially arranged around the opening of the upper shell 112. The upper shell 112 is provided with a first groove 1121 adapted to the first protrusion 1111, and the first protrusion 1111 is inserted into the first groove 1121. In this way, on the one hand, the first protrusion 1111 and the first groove 1121 cooperate with each other, which can improve the sealing performance, add an additional oil retaining groove, and realize secondary oil retaining, thereby effectively preventing oil from entering the interior of the shell 11; on the other hand, it can play a guiding role during assembly and facilitate installation. In addition, the first protrusion 1111 can also increase the structural strength of the lower shell 111.

[0047] Furthermore, a first sealing member is disposed inside the first groove 1121 and abuts against the first protrusion 1111. In this way, the sealing property of the housing 11 can be further improved, and the oil and smoke isolation performance of the housing 11 can be improved. The first sealing member includes but is not limited to a sealing ring or a sealing gasket.

[0048] In some embodiments, the first protrusion 1111 can be a continuous closed loop body arranged circumferentially around the opening of the upper shell 112, that is, one point of the first protrusion 1111 is selected as the starting point, and the first protrusion 1111 can be moved one circle from the starting point to return to the starting point; or it can be a plurality of segments 1112 arranged in sequence at intervals around the opening of the upper shell 112, and the interval positions of two adjacent segments 1112 specifically correspond to the positions of the buckles 1122 described below, so as to satisfy the mold processing technology.

[0049] In some embodiments, the lower shell 111 is provided with a second groove arranged circumferentially around the opening, and the upper shell 112 is provided with a second protrusion adapted to the second groove, and the second protrusion is inserted into the second groove. In this way, on the one hand, the second protrusion cooperates with the second groove to improve the sealing performance, add an additional oil blocking groove, and realize secondary oil blocking, thereby effectively preventing oil from entering the interior of the housing 11; on the other hand, it can play a guiding role during assembly and facilitate installation. In addition, the second protrusion can also increase the structural strength of the upper shell 112.

[0050] Furthermore, a second sealing member is disposed inside the second groove and abuts against the second protrusion. In this way, the sealing property of the housing 11 can be further improved, and the oil and smoke isolation performance of the housing 11 can be improved. The second sealing member includes but is not limited to a sealing ring or a sealing gasket.

[0051] See also Figure 8In one embodiment, the oil guide member 12 includes a first oil guide plate 121 connected to the outer wall of the housing 11 and a second oil guide plate 122 spaced apart from the outer wall of the housing 11. The first oil guide plate 121 is connected to the middle part of the second oil guide plate 122 on the side away from the housing 11, and the first oil guide plate 121, the second oil guide plate 122 and the outer wall of the housing 11 enclose an oil guide groove 13 and a first groove 1121. In this way, the cross-sectional profile of the oil guide member 12 and the outer wall of the housing 11 along the oil guide direction is H-shaped, which is conducive to achieving uniform wall thickness and preventing material deformation during mold forming process, so that the product processing quality is higher. In addition, the oil guide groove 13 and the first groove 1121 respectively play the role of separating oil and dirt, that is, they play the role of double-layer oil separation.

[0052] It should be noted that the "oil guide component 12" can be a "part of the upper shell 112", that is, the "oil guide component 12" and the "other parts of the upper shell 112" are manufactured as one piece; it can also be an independent component that can be separated from the "other parts of the upper shell 112", that is, the "oil guide component 12" can be manufactured independently and then combined with the "other parts of the upper shell 112" into a whole.

[0053] In one embodiment, the oil guide member 12 and the upper shell 112 are integrally formed by sheet metal, die casting or injection molding, so that batch production can be achieved with high production efficiency.

[0054] In some embodiments, the connection method between the upper shell 112 and the lower shell 111 can be flexibly selected according to actual needs and is not limited here. The upper shell 112 and the lower shell 111 can be fixed by welding, such as ultrasonic welding, or by clamping, or by gluing, etc.

[0055] See also Figures 2 to 4 In one embodiment, the upper shell 112 is provided with one or more buckles 1122, and the buckles 1122 are fixedly engaged with the oil guide member 12. Specifically, at least one buckle 1122 is respectively provided on two opposite sides of the upper shell 112, for example, two, three or more buckles 1122, and are respectively fixedly engaged with the oil guide member 12. In this way, the upper shell 112 and the lower shell 111 can be firmly connected, and the upper shell 112 and the lower shell 111 can be quickly disassembled.

[0056] See also Figures 1 to 4 In one embodiment, the lighting lamp 10 further includes at least one fixing spring buckle 14 connected to the top surface of the housing 11. The fixing spring buckle 14 is used for snap-fitting with the smoke collecting hood 20.

[0057] In some embodiments, the illuminating lamp 10 further includes a fastener 15. A first fastening hole 142 is provided on the fixing spring buckle 14, and a second fastening hole 113 corresponding to the first fastening hole 142 is provided on the housing 11. The fastener 15 passes through the first fastening hole 142 and the second fastening hole 113 to fix the fixing spring buckle 14 to the housing 11. There are more than two first fastening holes 142, second fastening holes 113, and fasteners 15, and each first fastening hole 142 and each second fastening hole 113 are respectively arranged corresponding to each fastener 15. The fastener 15 includes but is not limited to screws, pins, rivets, etc., and the first fastening hole 142 and the second fastening hole 113 are arranged corresponding to the fastener 15.

[0058] The fixing spring buckle 14 is provided with two elastic clamping parts 141 extending out from the left and right sides of the housing 11 respectively, and the smoke collecting plate 211 is formed with a mounting hole 212 for mounting the illuminating lamp 10, and the two elastic clamping parts 141 are respectively engaged with the hole wall of the mounting hole 212.
