[0031] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0032] This utility model discloses an oil guiding structure for use in a range hood. Please refer to [link / reference]. Figures 1 to 4 ,include:

[0033] The range hood body 1 has a smoke collection chamber 11. The bottom plate of the smoke collection chamber 11 has an oil outlet hole 111. The smoke collection chamber 11 has a first oil receiving plate 2 and a second oil receiving plate 3. The first oil receiving plate 2 is used to receive the oil discharged by the exhaust fan of the range hood. The second oil receiving plate 3 is used to receive the oil discharged by the first oil receiving plate 2 and guide the oil to the side of the bottom plate of the smoke collection chamber 11 with the oil outlet hole 111. The oil outlet hole 111 discharges the oil in the smoke collection chamber 11.

[0034] Overall, the horizontal planes of both the first oil receiving tray 2 and the second oil receiving tray 3 are higher than the horizontal plane of the bottom plate of the smoke collection chamber 11, and the first oil receiving tray 2 is located directly below the exhaust fan of the range hood, so that when the exhaust fan of the range hood discharges oil, the oil will directly and preferentially contact the first oil receiving tray 2.

[0035] Both the first oil receiving tray 2 and the second oil receiving tray 3 are inclined downwards from front to back, with the front end of each tray higher than the rear end. This ensures that after oil drips onto the first oil receiving tray 2, it flows towards the second oil receiving tray 3. The second oil receiving tray 3 then receives and guides the oil to the side of the bottom plate of the smoke collection chamber 11 where the oil outlet 111 is located, ultimately discharging the oil from the smoke collection chamber 11 through the outlet 111. In this way, the first and second oil receiving trays 2 and 3 directly form a barrier when the oil is discharged downwards from the exhaust fan, ensuring that the oil is directed to the outlet 111. This prevents oil from passing through other locations, such as the air intake, where it could accumulate and cause oil dripping. Furthermore, the entire process changes the direction of oil flow, preventing it from passing through the air intake. This eliminates the potential for oil accumulation and dripping due to oil flowing through the air intake, ensuring the cleanliness and dryness of the range hood's air intake, improving the stability and reliability of the range hood's operation, and reducing the hassle for users to clean the air intake of oil stains later.

[0036] The first oil receiving plate 2 and the second oil receiving plate 3 are both open at the top to ensure that when the first oil receiving plate 2 receives the dripping oil, the oil will not flow out from its end, and when the second oil receiving plate 3 receives the oil flowing out of the first oil receiving plate 2, the oil will not flow out from its end, so that all the oil on the second oil receiving plate 3 can be discharged from the oil outlet 111.

[0037] The oil guiding structure of this utility model has oil outlets 21 at both ends of the rear side of the first oil receiving plate 2, and two second oil receiving plates 3. The two second oil receiving plates 3 are connected to the rear ends of the first oil receiving plate 2, and the oil in the first oil receiving plate 2 flows into the corresponding second oil receiving plate 3 through the oil outlets 21.

[0038] In this invention, the first oil receiving tray 2 is closer to the operating side of the range hood body 1 than the second oil receiving tray 3, i.e., the side where the user stands and operates. In other words, the front side of the first oil receiving tray 2 is the side closer to the user's standing and operating position.

[0039] Based on the above embodiment, the rear side of the first oil receiving tray 2 is its lower end when it is installed at an angle, so that when the first oil receiving tray 2 receives the dripping oil, the oil can flow out from the oil outlet 21 and into the corresponding second oil receiving tray 3. The first oil receiving tray 2 has two oil outlets 21, which are respectively located at two included angles at its lower end, to ensure that when the dripping oil falls at any position on the first oil receiving tray 2, it can be quickly discharged from the nearest oil outlet 21.

[0040] Furthermore, the tops of the two second oil receiving pans 3 are located below the bottom of the first oil receiving pan 2, so as to receive the oil flowing out of the corresponding oil outlet 21 through the two second oil receiving pans 3.

[0041] When the exhaust fan stops running, the oil will be discharged from the volute and drip down onto the first oil receiving plate 2. Guided by the first oil receiving plate 2, the oil is directed to the corresponding oil outlet 21. Through the oil outlet 21, the oil is directed to the corresponding second oil receiving plate 3. Then, through the receiving and guiding of the second oil receiving plate 3, the oil is directed to the side of the bottom plate of the smoke collection chamber 11 where the oil outlet 111 is provided. Finally, the oil in the smoke collection chamber 11 is discharged through the oil outlet 111, which improves the problem of oil dripping at the air intake caused by too much oil passing through the air intake and gradually cooling down.

[0042] The oil guiding structure of this utility model has an air intake 112 on the bottom plate of the smoke collection chamber 11, the air intake 112 is located in front of the oil outlet 111, the first oil receiving plate 2 is located in front of the air intake 112, and the second oil receiving plate 3 guides the oil received by the first oil receiving plate 2 to the part of the bottom plate of the smoke collection chamber 11 located behind the air intake 112.

[0043] In this invention, the first oil receiving tray 2 and the two second oil receiving trays 3 connected to the corresponding oil outlet 21 at the top together form a "U"-shaped opening structure. On the horizontal projection, the air intake 112 is located inside the opening of the "U"-shaped opening formed by the first oil receiving tray 2 and the two second oil receiving trays 3, so as to ensure that when the range hood is started and the oil fumes are sucked through the air intake 112, neither the first oil receiving tray 2 nor the two second oil receiving trays 3 will affect the suction and exhaust of the oil fumes.

[0044] Overall, the horizontal planes of both the first oil receiving tray 2 and the second oil receiving tray 3 are higher than the horizontal plane of the air intake 112.

[0045] Furthermore, the first oil receiving tray 2 is located directly below the exhaust fan of the range hood, so that when the exhaust fan discharges oil, the oil will directly and preferentially contact the first oil receiving tray 2. Guided by the first oil receiving tray 2 and the second oil receiving tray 3, the oil will be guided from the front of the air intake 112 to the rear of the air intake 112, so that the oil will not fall onto the air intake 112 and will not accumulate in the air intake 112. This eliminates the hidden danger of oil accumulation and dripping due to oil flowing through the air intake 112, ensuring the cleanliness and dryness of the range hood's air intake, improving the stability and reliability of the range hood's operation, and reducing the trouble for users to clean the oil stains in the air intake later.

[0046] In this utility model's oil guiding structure, the second oil receiving tray 3 spans across the air intake 112 and covers the portion of the cover plate of the range hood body 1 that aligns with the air intake 112. This way, when oil adhering to and accumulating on the cover plate of the range hood body 1 reaches a certain amount and drips downwards, it will be caught by the second oil receiving tray 3, preventing oil droplets from dripping out of the air intake 112 onto the outside of the range hood and affecting the user experience.

[0047] For the oil guiding structure of this utility model, please refer to [link / reference]. Figures 1 to 4 , Figure 6 as well as Figure 7 The air intake 112 is provided with an upwardly folded and extended flange 1121. The flange 1121 is in a constricted shape. The flange 1121 at the upper edge of the air intake 112 is used to prevent the oil from the part of the bottom plate of the smoke collection chamber 11 located in front of the air intake 112 from dripping out through the air intake 112. The flanges 1121 on both sides of the air intake 112 are used to guide the oil accumulated at the flange 1121 at the upper edge of the air intake 112 to the rear side of the air intake 112.

[0048] The opening size of the constricted flange 1121 is larger than the upper opening size, and the tilt angle of the flange 1121 can be 120°, 125°, or 130°, etc.

[0049] When the bottom of the smoke collection chamber 11 receives the oil falling from the second oil receiving tray 3, the upwardly folded and extended flange 1121 forms a barrier around the air intake 112, preventing the oil on the bottom of the smoke collection chamber 11 from being directed to the air intake 112, thus avoiding dripping downwards from the air intake 112. At the same time, the annular flange 1121 increases the structural strength of the bottom plate of the smoke collection chamber 11, forming a reinforcing rib.

[0050] The oil guiding structure of this utility model has a guide plate 4 in the smoke collection chamber 11. The guide plate 4 has a clearance opening arranged around the air intake 112. The upper and lower edges of the clearance opening are provided with oil baffles 41. The oil baffles 41 at the upper edge of the clearance opening are inclined upward from front to back, and the oil baffles 41 at the lower edge of the clearance opening are inclined upward from back to front. The oil baffles 41 at the lower edge of the clearance opening are provided with oil drain holes 411. The oil between the air intake 112 and the oil baffles 41 at the lower edge of the clearance opening is discharged through the oil drain holes 411 to the side of the smoke collection chamber 11 where the oil outlet hole 111 is provided.

[0051] The guide plate 4 has a vertical through opening to form a clearance opening that matches the air intake 112. After installation, the clearance opening is set around the air intake 112, and the guide plate 4 has an overall inclined structure. The end closer to the operator is the top, and the other end is the bottom. That is, the upper edge of the clearance opening is close to the top of the guide plate 4, and the lower edge of the clearance opening is close to the bottom of the guide plate 4. The oil outlet 111 is located at the lower edge of the clearance opening away from the upper edge of the clearance opening.

[0052] When oil appears on the upper edge of the guide plate 4 at the clearance opening, the oil baffle 41 at the upper edge of the clearance opening can act as a barrier to prevent the oil from passing over the oil baffle 41 and entering the air intake 112. Furthermore, when oil appears in the space between the air intake 112 and the oil baffle 41 at the lower edge of the clearance opening, the oil in this space can be discharged through the oil drain hole 411 under the tilting action of the bottom plate of the smoke collection chamber 11, and then discharged from the oil outlet hole 111, further preventing the oil from accumulating at the oil outlet hole 111 and dripping from it.

[0053] The oil guiding structure of this utility model includes a wind-guiding and liquid-guiding component 5 arranged around the flange 1121 in the smoke collection chamber 11. The wind-guiding and liquid-guiding component 5 is provided with a first oil guiding groove 51 and a wind guiding plate 52. The first oil guiding groove 51 is arranged around the flange 1121. The wind-guiding and liquid-guiding component 5 is also provided with an oil leakage hole 511, which is connected to the side of the first oil guiding groove 51 near the oil outlet 111. The wind guiding plate 52 is arranged along the upper edge of the first oil guiding groove 51 and is flared. A second oil guiding groove 412 is formed between the oil baffle plate 41 and the wind-guiding and liquid-guiding component 5.

[0054] The air guide and liquid guide component 5 is arranged around the flange 1121, surrounding the outer side of the flange 1121, which can enhance the structure of the flange 1121. The flange 1121 is constricted, and the inner end of the air guide and liquid guide component 5 near the air intake 112 is a constricted structure that matches the flange 1121. The air guide and liquid guide component 5 is inclined as a whole, and the upper end is fixedly connected to the air guide plate 52. The lower end of the air guide plate 52 is fixedly connected to the outer end of the air guide and liquid guide component 5, forming a first oil guide groove 51 between them. When oil drips and accumulates at the flange 1121, it will accumulate on the first oil guide groove 51. At this time, under the inclination of the air guide and liquid guide component 5, it will flow around the first oil guide groove 51 toward the low-lying area of ​​the inclined first oil guide groove 51. The upper end of the air guide plate 52 has an flared structure opposite to that of the air guide liquid guide 5, and the inner end of the air guide liquid guide 5 has a constricted structure with a smaller size than the minimum size of the upper end of the air guide plate 52. This is so that when the oil drips down onto the air guide plate 52, the oil can drip into the first oil guide groove 51 for collection, thus preventing the oil from dripping from the air intake 112.

[0055] An oil drain hole 511 is provided on the air guide plate 52 so that when the oil in the first oil guide groove 51 flows to the low point of the first oil guide groove 51, the oil can flow out from the oil drain hole 511 and be discharged into the second oil guide groove 412, away from the air intake 112, preventing the oil from dripping from the air intake 112. Furthermore, through the oil drain hole 411 provided on the oil baffle plate 41 at the lower edge of the clearance, the oil drain hole 411 is connected to the second oil guide groove 412, so that the oil in the second oil guide groove 412 can be discharged from the oil drain hole 411, and then discharged from the oil outlet 111, to further prevent the oil from stagnating at the oil outlet 111 and dripping from the oil outlet 111.

[0056] In the oil guiding structure of this utility model, the front edge of the guide plate 4 extends upward to a support plate 42, and the main body 1 of the range hood is also provided with a partition plate 6. The first oil receiving tray 2 is connected to the partition plate 6 and the support plate 42, and the front end of the second oil receiving tray 3 is connected to the support plate 42, and the rear end is connected to the rear plate of the smoke collection chamber 11.

[0057] By setting up a support plate 42, the first oil receiving tray 2 and the second oil receiving tray 3 are simultaneously supported, ensuring that both the first oil receiving tray 2 and the second oil receiving tray 3 are stably installed and guaranteeing the long-term stability of oil guiding in both trays. The support plate 42 extends upwards and then forwards, and can be connected to the lower side of the first oil receiving tray 2 via screws or other connectors. The second oil receiving tray 3 is connected to the support plate 42 via an extension plate.

[0058] For the oil guiding structure of this utility model, please refer to [link / reference]. Figure 1 and Figure 2 The rear end of the second oil receiving plate 3 is provided with an oil drain port 31, which discharges the oil on the second oil receiving plate 3.

[0059] When the oil is guided by the second oil receiving plate 3 to the side of the bottom plate of the smoke collection chamber 11 with the oil outlet 111, the oil outlet 31 of the second oil receiving plate 3 is located at the rear end of the second oil receiving plate 3, that is, at the lower end of the inclined end, so that the oil on the second oil receiving plate 3 can be discharged from the oil outlet 31 in time, and finally discharged from the smoke collection chamber 11 through the oil outlet 111.

[0060] Based on the above embodiment, a recessed platform is provided on the side of the bottom plate of the smoke collection chamber 11 where the oil outlet 111 is provided. The oil outlet 111 is located at the recessed platform so that the recessed platform is the lowest point, ensuring that the oil can flow out from the oil outlet 111 at the lowest point.

[0061] For the oil guiding structure of this utility model, please refer to [link / reference]. Figure 3 and Figure 4 ,as well as Figure 6 and Figure 7 The main body 1 of the smoke hood also has an electrical control cavity 12. The partition plate 6 is located between the smoke collection cavity 11 and the electrical control cavity 12. The electrical control cavity 12 is located in front of the partition plate 6, and the smoke collection cavity 11 is located behind the partition plate 6. The functional components of the smoke hood are located in the electrical control cavity 12.

[0062] In use, the electrical control cavity 12 is used to install functional components, which may be lighting components, air curtain components, or air quality detection modules. The main body 1 of the range hood has air curtain inlets corresponding to the air curtain components and detection holes corresponding to the air quality detection modules. The base plate has air curtain outlets corresponding to the air curtain components and lighting windows corresponding to the lighting components. During use, the air curtain components activate and form an air curtain between the user and the cooktop to prevent the escape of cooking fumes. The lighting components illuminate the area so the user can clearly see the state of the cooking ingredients. The air quality detection module monitors the air quality in real time to determine the range hood's smoke removal effect.

[0063] By using the partition plate 6, the oil fumes are isolated in the smoke collection chamber 11, preventing them from entering the electrical control chamber 12 and contaminating the functional components. This keeps the functional components clean for a long time, thus improving the technical problem that existing range hoods can easily damage the functional components inside the chamber when fumes are emitted, leading to increased cleaning and replacement costs.

[0064] The partition plate 6 physically separates the electrical control chamber 12 and the smoke collection chamber 11, providing better functional isolation and protection. For the electrical control chamber 12, it prevents impurities such as oil fumes and dust that may be present in the smoke collection chamber 11 from entering, reducing corrosion and contamination of the electrical control components, extending the service life of functional components, and ensuring the stable operation of the electrical control system. For the smoke collection chamber 11, it also avoids unnecessary interference to the smoke collection function caused by malfunctions in the electrical control components, further enhancing the independence and reliability of each functional module.

[0065] In addition, the partition plate 6 can act as a physical partition, structurally stabilizing the boundary between the two cavities and preventing deformation or mutual interference of the two cavities due to external vibrations or other factors during use. This helps maintain the stability of the entire range hood's internal structure and ensures the normal operation of all functions.

[0066] Please see Figures 1 to 7 This utility model provides a range hood that adopts the above-mentioned oil guiding structure, including an air collecting box 7, which is connected to the main body 1 of the range hood and communicates with the smoke collecting chamber 11. An exhaust fan 8 is provided inside the air collecting box 7, and the volute of the exhaust fan 8 is provided with an oil dripping hole, which is aligned with the first oil receiving plate 2.
