[0032] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] This utility model provides a range hood, such as Figure 1 As shown, the range hood includes a housing 1 and a fan installed inside the housing 1. The housing 1 has an air inlet 11. When the fan is started, it can create a negative pressure inside the housing 1, so that the oil fumes near the air inlet 11 are drawn into the housing 1 and discharged through the exhaust pipe, thereby achieving the purpose of purifying the kitchen environment.

[0037] To facilitate cooking, range hoods typically have lights installed on the bottom panel. These lights provide illumination for the user while cooking, making it easier for them to see the food. However, when grease seeps into or drips onto the inside of the panel, it can easily flow to the light source, contaminating the light-emitting surface and affecting its effectiveness. It can also corrode the wiring, potentially damaging the light.

[0038] like Figures 2-4 As shown, to solve the above problems, this embodiment provides a panel assembly 2, which includes a fixed back plate 21 and a lighting lamp 22. The fixed back plate 21 includes a back plate body 211 and an oil-blocking flange 212 disposed on the back plate body 211. The back plate body 211 is provided with a light-transmitting area 215, and the oil-blocking flange 212 is disposed around the outer periphery of the light-transmitting area 215. The lighting lamp 22 is disposed inside the oil-blocking flange 212, and the lighting lamp 22 illuminates the light-transmitting area 215.

[0039] The panel assembly 2 is fixedly mounted on the housing 1. The back panel body 211 is used to fix the lighting lamp 22, ensuring the stability of the lighting lamp 22. The lighting lamp 22 can illuminate the light-transmitting area 215 to facilitate cooking. The oil-blocking flange 212 is arranged around the outer periphery of the light-transmitting area 215 to block oil stains that seep into or drip onto the inner side of the back panel body 211, preventing oil stains from directly contacting the lighting lamp 22. This panel assembly 2 can prevent the lighting lamp 22 from being affected by oil stains, ensuring lighting effect and service life.

[0040] It is worth noting that the back panel body 211 can form a light-transmitting area 215 by setting lighting holes or by setting light-transmitting material, as long as the light generated by the lighting lamp 22 can pass through the light-transmitting area 215 for illumination.

[0041] like Figures 3-5 As shown, in this embodiment, the lighting lamp 22 includes a lamp body 221 and a sealing ring 222. The lamp body 221 is disposed within the oil-blocking flange 212, and the sealing ring 222 is disposed around the lamp body 221 and located between the lamp body 221 and the oil-blocking flange 212. The lamp body 221 is used to illuminate and emit light, and the light is emitted from the lamp body 221 toward the light-emitting surface of the back plate body 211. The sealing ring 222 can seal the gap between the lamp body 221 and the oil-blocking flange 212, preventing the misty vapor of oil droplets from directly contacting the light-emitting surface of the lamp body 221, thus ensuring the lighting effect of the lamp body 221.

[0042] like Figure 5 As shown, in order to further improve the sealing performance of the lamp body 221, a sealing edge 2211 is provided on the outer periphery of the lamp body 221. The sealing ring 222 includes an upper sealing part 2221, a lower sealing part 2223, and a connecting part 2222 that connects the upper sealing part 2221 and the lower sealing part 2223. The connecting part 2222 is arranged around the outer periphery of the sealing edge 2211. The upper sealing part 2221 is located on the upper side of the sealing edge 2211, and the lower sealing part 2223 is located on the lower side of the sealing edge 2211.

[0043] This structure of the sealing ring 222 can seal the gap between the sealing edge 2211 and the oil-blocking flange 212 through the connecting part 2222, and can also seal the gap between the sealing edge 2211 and the back plate body 211 through the lower sealing part 2223. This double barrier is provided on the path of the misty vapor of oil droplets to the light-emitting surface of the lamp body 221, ensuring that the light-emitting surface of the lamp body 221 is not contaminated. The upper sealing part 2221 can improve the stability and reliability of the connection between the sealing ring 222 and the sealing edge 2211, ensuring the shape stability of the sealing ring 222 and preventing local deformation, thereby ensuring the sealing performance.

[0044] If the back panel body 211 is provided with an illumination hole to form a light-transmitting area 215, then the lower sealing part 2223 is located between the portion of the back panel body 211 located at the outer edge of the illumination hole and the sealing edge 2211; if the back panel body 211 is provided with a light-transmitting material to form a light-transmitting area 215, then the lower sealing part 2223 is located between the light-transmitting material and the sealing edge 2211, or between the portion of the back panel body 211 located at the outer edge of the light-transmitting material and the sealing edge 2211.

[0045] In this embodiment, the panel assembly 2 further includes a first fixing screw, such as Figure 4 As shown, the backplate body 211 is provided with first fixing flanges 213 at intervals. First fixing screws fix the lamp body 221 to the first fixing flanges 213, and the sealing edge 2211 presses the lower sealing part 2223 against the backplate body 211. The first fixing screws can fix the lamp body 221 to the first fixing flanges 213, thereby ensuring the stability of the lamp body 221. Moreover, during the rotation of the first fixing screws, the lamp body 221 will be pressed towards the backplate body 211, so that the lamp body 221 can squeeze the lower sealing part 2223 against the backplate body 211, further improving the sealing effect of the sealing ring 222.

[0046] Generally, a range hood needs to cover the positions of two cooktops on a gas stove. Therefore, to ensure lighting performance, the panel assembly 2 includes at least two lights 22, which are spaced apart on the back panel body 211. The at least two lights 22 increase the illumination range of the range hood, ensuring effective lighting regardless of which cooktop the user is using.

[0047] In some embodiments, the panel assembly 2 includes two lights 22, with one light 22 located above one burner of the gas stove and the other light 22 located above the other burner of the gas stove.

[0048] like Figure 3 and Figures 6-8 As shown, panel assembly 2 also includes a temperature sensing module 23, which includes a housing 231 and a temperature sensing probe 232. The housing 231 is fixedly mounted on the back panel body 211, and the temperature sensing probe 232 is used to detect the temperature of the back panel body 211. The housing 231 is used to fix and protect the temperature sensing probe 232. The temperature sensing probe 232 is used to detect the temperature of the back panel body 211, and can promptly remind the user when the temperature of the back panel body 211 is too high, ensuring that the range hood operates within the normal temperature range, and also ensuring that the temperature of the lighting lamp 22 is normal, avoiding damage to components caused by excessive temperature of the back panel body 211.

[0049] Understandably, the temperature sensing module 23 senses temperature through the temperature sensing probe 232, and it also needs to avoid direct contact with the back panel body 211 to prevent high temperatures from affecting electronic components. To achieve this, the housing 231 is provided with several heat-insulating support members 233, which abut against the back panel body 211. By providing the heat-insulating support members 233, direct contact between the housing 231 and the back panel body 211 can be avoided, thereby minimizing the temperature of the housing 231 and preventing any impact on the internal structure of the housing 231.

[0050] like Figure 6As shown, in order to control the temperature sensing probe 232 to perform temperature sensing, the temperature sensing module 23 also includes a circuit board 234. The circuit board 234 is communicatively connected to the temperature sensing probe 232. However, the circuit board 234 is not resistant to high temperatures and should not operate at excessively high temperatures, otherwise it will be easily damaged. To protect the circuit board 234, the housing 231 includes a heat insulation part 2311 and a fixing part 2312 connected to each other. The temperature sensing probe 232 is disposed in the fixing part 2312, and the circuit board 234 is disposed in the heat insulation part 2311. The heat insulation part 2311 and the back plate body 211 are spaced apart.

[0051] The fixing part 2312 is used to abut against the back plate body 211 to ensure the stability of the temperature sensing module 23. Therefore, the heat insulation support 233 is set on the fixing part 2312 to avoid the temperature of the temperature sensing probe 232 in the fixing part 2312 being too high. The heat insulation part 2311 is spaced apart from the back plate body 211, which can move the heat insulation part 2311 away from the back plate body 211, further reducing the temperature of the heat insulation part 2311, thereby ensuring that the circuit board 234 in the heat insulation part 2311 is at a suitable temperature.

[0052] Furthermore, a support column 325 protrudes from the side of the heat insulation part 2311 facing the back plate body 211, and the support column 325 abuts against the back plate body 211. The support column 325 can provide support for the heat insulation part 2311, preventing the heat insulation part 2311 from being completely suspended, ensuring the overall force balance of the outer shell 231, and improving the stability of the temperature sensing module 23.

[0053] like Figure 7 As shown, in order to ensure the strength of the support column 325, the outer shell 231 is also provided with a reinforcing rib 236, which connects the side wall of the support column 325 and the heat insulation part 2311.

[0054] Furthermore, the reinforcing rib 236 extends to the connecting fixing part 2312, thereby increasing the strength of the reinforcing rib 236 itself and also increasing the overall strength of the heat insulation part 2311, ensuring that the outer shell 231 can provide good support and protection for the circuit board 234.

[0055] In this embodiment, the panel assembly 2 further includes a second fixing screw, such as Figure 8 As shown, the backplate body 211 is provided with second fixing flanges 214 at intervals, and second fixing screws fix the outer shell 231 to the second fixing flanges 214. The second fixing screws can fix the outer shell 231 of the temperature sensing module 23 to the second fixing flanges 214, while the heat insulation support 233 and the support column 325 of the temperature sensing module 23 abut against the backplate body 211, which can ensure the stability of the temperature sensing module 23.
