[0027] This utility model provides a lighting installation structure for use with range hoods, for lighting the stove area below the range hood.

[0028] Reference Figures 1 to 6 The lighting fixture installation structure includes a housing 1, a lamp housing 2, and a lamp body 3.

[0029] like Figure 1 and Figure 2 As shown, the bottom of the housing 1 has an upwardly recessed smoke collection chamber 11, which contains a smoke inlet 101 and a wire passage hole 102. An air duct is provided inside the housing 1, and the fumes enter the air duct through the smoke inlet 101. The wire passage hole 102 is used to pass the wires of the lamp body 3.

[0030] The lamp housing 2 is disposed within the smoke collection chamber 11 and covers the wire hole 102. The edge of the lamp housing 2 is fitted to the bottom surface of the housing 1 and connected by fasteners. The lamp housing 2 and the housing 1 form a mounting cavity. A lamp hole 201 is formed on the bottom plate of the lamp housing 2. The lamp body 3 is disposed in the mounting cavity and mates with the lamp hole 201. The wires of the lamp body 3 pass through the wire hole 102.

[0031] A sealant or sealant can be installed inside the wire hole 102 to fix the wire of the lamp body 3 and prevent oil leakage from the wire hole 102.

[0032] This utility model discloses a lighting fixture mounting structure in which the lamp body 3 is mounted on the lamp housing 2. The edge of the lamp housing 2 is connected to the housing 1 by fasteners, and a lamp hole 201 is provided to mount the lamp body 3. Compared with the traditional mounting method of directly opening a lamp hole in the housing to mount the lamp body 3, the lamp housing 2 and the housing 1 of this utility model are connected by fasteners, resulting in fewer installation gaps on the housing 1 and reducing the problem of oil seepage. Even if a small amount of oil seepage occurs at the edge of the lamp housing 2, it will not affect the lighting effect of the lamp body 3. Furthermore, the lamp housing 2 and the housing 1 also have the advantages of simple structure, low cost, and easy installation and disassembly.

[0033] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the four edges of the lamp housing 2 form inwardly bent edges 202 that fit against the housing 1. Multiple mounting holes 203 for fasteners are provided on the edges 202. The edges 202 fit tightly against the housing 1, improving the installation stability of the lamp housing 2. The housing 1 has fixing holes 103 corresponding to the mounting holes 203, and fasteners are connected to the housing 1 through the fixing holes 103. Fasteners can be screws, rivets, pins, or other conventional fasteners. The edges 202 and fasteners are hidden inside the lamp housing 2, maintaining an aesthetically pleasing appearance and preventing oil seepage from the edges of the lamp housing 2.

[0034] Furthermore, an upwardly extending flange 104 is formed at the edge of the fixing hole 103. The flange 104 surrounds and protrudes from the fixing hole 103, which can prevent oil condensation on the inner surface of the housing 1 from entering the fixing hole 103, effectively reducing the problem of oil leakage.

[0035] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the smoke collection chamber 11 includes a forward-inclined plate 111 and a backward-inclined plate 112. The forward-inclined plate 111 is positioned with a lower front and a higher rear, while the backward-inclined plate 112 is positioned with a higher front and a lower rear, forming an included angle. A smoke inlet 101 can be disposed on the forward-inclined plate 111 and the backward-inclined plate 112. Oil fumes entering the housing 1 from the smoke collection chamber 11 condense on the top surfaces of the forward-inclined plate 111 and the backward-inclined plate 112, and the condensed oil flows downwards along the forward-inclined plate 111 and the backward-inclined plate 112. The lamp housing 2 is fixedly connected to the forward-inclined plate 111 and the backward-inclined plate 112.

[0036] Furthermore, such as Figure 1 As shown, the smoke collection chamber 11 also includes left and right side-tilting plates 113, which are connected to the left and right edges of the front tilting plate 111 and the rear tilting plate 112. The smoke collection chamber 11 is formed between the front tilting plate 111, the rear tilting plate 112 and the side-tilting plates 113 on both sides.

[0037] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the housing 1 also includes a rear guide vane 12, which extends downward from the rear edge of the rear tilting plate 112 to guide condensed oil. An oil collection trough can be provided at the bottom of the rear guide vane 12 to collect condensed oil. The condensed oil formed inside the housing 1 eventually enters the oil collection trough.

[0038] In detail, the bottom of the housing 1 is designed to be higher at the front and lower at the rear, with the front end of the forward tilting plate 111 higher than the rear end of the rear tilting plate 112. For ease of description, the acute angle between the inclined plane and the horizontal plane is defined as the tilt angle in this specification. The tilt angle of the rear tilting plate 112 is smaller than that of the forward tilting plate 111, and the length of the rear tilting plate 112 in the longitudinal direction is greater than that of the forward tilting plate 111 in the longitudinal direction, resulting in a larger area for the rear tilting plate 112. Condensed oil mainly forms on the surface of the rear tilting plate 112. The wire passage hole 102 can be located on the forward tilting plate 111. The condensed oil on the forward tilting plate 111 is relatively less and flows at a faster rate, reducing the risk of oil leakage from the wire passage hole 102.

[0039] like Figure 1 and Figure 2 As shown, the housing 1 is also provided with an edge plate 13, which is connected to the front edge and the left and right side edges of the smoke collection chamber 11. The rear end of the edge plate 13 is connected to the rear guide plate 12. The edge plate 13 slopes downward from the front end to the rear end to guide the condensed oil to the rear guide plate 12.

[0040] In some embodiments of this utility model, the front tilting plate 111, rear tilting plate 112, side tilting plate 113, rear guide plate 12 and edge plate 13 of the housing 1 are an integral structure, which has good sealing performance and is not easy to leak oil.

[0041] In some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, side plates 22 are respectively provided on the left and right sides of the base plate 21 of the lamp housing 2. The side plates 22 cooperate with the forward tilting plate 111 and the rear tilting plate 112. The front and rear edges of the base plate 21 and the edges of the two side plates 22 form folded edges 202. The side plates 22 are approximately triangular, with the front edge of the side plate 22 cooperating with the forward tilting plate 111 and the rear edge of the side plate 22 cooperating with the rear tilting plate 112.

[0042] Specifically, the flanges 202 on the front edges of the two side plates 22 and the flanges 202 on the front edges of the bottom plate 21 are respectively connected to the forward tilting plate 111 by fasteners. The flanges 202 on the rear edges of the two side plates 22 are respectively connected to the rear tilting plate 112 by fasteners. The flanges 202 on the rear edge of the bottom plate 21 are connected to the rear deflector 12 by fasteners.

[0043] Since there is a lot of solidified oil on the tilting plate 112, the number of fixing holes 103 on the tilting plate 112 can be reduced to reduce oil leakage.

[0044] like Figure 3 In the embodiment shown, only two fixing holes 103 are provided on the tilt plate 112, and the folded edges 202 of the rear edges of the two side plates 22 are respectively connected to the tilt plate 112 by a fastener.

[0045] In some embodiments of this utility model, the lamp hole 201 is located in the middle of the base plate 21, and the two side plates 22 of the lamp housing 2 extend obliquely from the left and right edges of the base plate 21 in a direction away from each other, so that the front and rear edges of the side plates 22 are far away from the lamp body 3, and oil stains are avoided from affecting the illumination of the lamp body 3.

[0046] In some embodiments of this utility model, an oil drain gap 211 is left between the rear edge of the base plate 21 of the lamp housing 2 and the rear guide plate 12, so that a small amount of condensed oil in the lamp housing 2 can be discharged from the oil drain gap 211 and then flow downward along the rear guide plate 12.

[0047] like Figure 6 In the embodiment shown, a certain distance is left between the folded edge 202 of the rear edge of the base plate 21 and the side plates 22 on the left and right sides, forming two oil drainage gaps 211.

[0048] In some embodiments of this utility model, the base plate 21, the two side plates 22, and the edge folding 202 of the lamp housing 2 are an integral structure, which helps to reduce oil leakage problems. The lamp housing 2 can be processed and formed from materials such as metal plates and plastic plates.

[0049] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the lamp housing 2 has positioning claws 204 on its edge, and the housing 1 has positioning holes 105 that mate with the positioning claws 204. By engaging the positioning claws 204 with the positioning holes 105, the lamp housing 2 can be positioned for installation, ensuring that the mounting holes 203 on the folded edge 202 correspond to the fixing holes 103 on the housing 1, facilitating the connection of fasteners. The positioning claws 204 can be located on the front edge, rear edge, or other positions of the lamp housing 2.

[0050] In some embodiments of this utility model, such as Figure 4 and Figure 5As shown, the positioning claw 204 is provided with a slot 2041, which can engage with the edge of the positioning hole 105, limiting the relative position of the positioning claw 204 and the positioning hole 105, and further positioning the lamp housing 2.

[0051] In some embodiments of this utility model, two positioning claws 204 are provided on the rear edge of the lamp housing 2. These two positioning claws 204 extend rearward from the rear ends of the left and right side plates 22, and are both sheet-like structures. A slot 2041 is formed on the top of each of the two positioning claws 204. Two corresponding positioning holes 105 are provided on the rear guide plate 12. The two positioning claws 204 are inserted into their respective positioning holes 105 and positioned by the slots 2041, ensuring accurate installation of the lamp housing 2.

[0052] The rear guide vane 12 is inclined backward from top to bottom, and the inclination angle of the rear guide vane 12 is greater than that of the rear incline 112. Both the front and rear surfaces of the rear incline 112 can guide the condensed oil. If the condensed oil on the rear guide vane 12 enters the positioning hole 105, it will continue to flow downward along the front surface of the rear guide vane 12.

[0053] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the edge of the lamp hole 201 forms an upwardly extending flange 205, which surrounds the lamp hole 201 to prevent the condensed oil on the base plate 21 from entering the lamp hole 201 and avoid oil stains from affecting the lighting effect.

[0054] In some embodiments of this utility model, the top of the flange 205 of the lamp housing 2 extends into the lamp hole 201 to form a limiting edge 206 for limiting the lamp body 3. The limiting edge 206 can install and position the lamp body 3.

[0055] Specifically, the bottom of the lamp body 3 is a light-transmitting plate 31, which is adapted to the lamp hole 201. The edge of the light-transmitting plate 31 protrudes outward and can engage with the limiting edge 206 to achieve the installation and positioning of the lamp body 3. During installation, the lamp body 3 can be inserted into the lamp hole 201 from bottom to top. The lamp body 3 can be fixedly connected to the lamp housing 2 by a bracket or fasteners.

[0056] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, to accommodate the shape of the existing lamp body 3, the forward tilting plate 111 and / or the rear tilting plate 112 can be provided with an upwardly recessed relief groove 106 to provide sufficient installation space for the lamp body 3. The shape and position of the relief groove 106 can be set according to the shape of the lamp body 3.

[0057] During installation, first assemble the lamp housing 2 and the lamp body 3, so that the light-transmitting plate 31 of the lamp body 3 matches the lamp hole 201, and pass the wire of the lamp body 3 through the wire hole 102 of the housing 1; then, position the lamp housing 2 on the housing 1 by the positioning claw 204, so that the mounting holes 203 on the folded edge 202 of the lamp housing 2 correspond to the fixing holes 103 of the housing 1 respectively, and then install the fasteners to fix the lamp housing 2 and the housing 1 together.

[0058] During use, the baffle 104 on the edge of the fixing hole 103 on the housing 1 can prevent condensed oil from entering the lamp housing 2. Prolonged operation of the range hood in a high-temperature environment may cause the wire hole 102 to fail to seal, resulting in condensed oil entering the lamp housing 2 along the surface of the forward tilting plate 111. The base plate 21 of the lamp housing 2 is designed with a higher front and lower rear, which can guide the condensed oil to the rear guide plate 12 on the rear side of the housing 1, preventing condensed oil from accumulating inside the lamp housing 2. The flange 205 on the edge of the lamp hole 201 can prevent condensed oil on the base plate 21 from entering the lamp hole 201, ensuring lighting effect and avoiding increased cleaning costs for the user.

[0059] This utility model also provides a range hood, including a lighting installation structure provided in the above embodiments of this utility model.

[0060] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
