Technical Field
[0001] This utility model relates to the field of smoke hood technology, specifically to a smoke hood. Background Technology
[0002] After a range hood has been running for a long time, oil will accumulate on the surface and inside of the exhaust fan casing. When the exhaust fan stops running, the oil inside the casing will be discharged from the oil drain hole at the bottom of the casing. The amount of oil discharged is relatively large. If there is no oil collection part to block it, the oil will be discharged directly from the bottom of the casing into the smoke collection chamber. This will cause the oil to splash and dirty the inner wall of the smoke collection chamber. There is also a risk that the oil will splash out through the air intake of the main body of the range hood. Utility Model Content

[0006] According to one embodiment of the present invention, the main body of the range hood has a suction panel, a suction port is provided on the suction panel, the suction port is connected to the smoke collection chamber, and the oil drip hole is located on the rear side of the suction port.
[0007] According to one embodiment of the present invention, the main body of the smoke hood includes a smoke collection box and an exhaust box. The exhaust box is located above the smoke collection box, and the smoke exhaust fan is located inside the exhaust box. The inner cavity of the smoke collection box and the inner cavity of the exhaust box are connected to form a smoke collection chamber.
[0008] According to one embodiment of the present invention, a bellows support is provided inside the smoke collection box, the smoke collection box has a cover plate, and an installation port is provided on the cover plate. The exhaust box is installed at the installation port and is supported by the bellows support.
[0009] According to one embodiment of the present invention, the suction panel is provided with a panel reinforcement plate, and the panel reinforcement plate is provided with a support part on the side near the oil receiving part. The higher end of the oil receiving part is connected to the air box bracket, and the lower end is connected to the support part of the panel reinforcement plate.
[0010] According to one embodiment of the present invention, an oil baffle is also provided in the smoke collection chamber.

[0014] Compared with the prior art, the smoke hood of this utility model has the following advantages:
[0015] This utility model of a range hood features an oil receiving component inside the smoke collection chamber. Oil discharged from the volute is collected by this component. Because the distance between the oil receiving component and the bottom of the volute is less than the distance between the bottom of the volute and the bottom of the smoke collection chamber, the oil droplets travel a shorter distance from the bottom of the volute to the oil receiving component, accumulating less kinetic energy. Consequently, the splashing on the oil receiving component is also reduced, preventing excessive splashing of oil when it is discharged from the volute to the oil receiving component, thus preventing oil from soiling the walls of the smoke collection chamber or splashing out of the air intake. Furthermore, the oil collected by the oil receiving component is discharged through an oil guide to the side of the smoke collection chamber with an oil drip hole, ensuring a clear and smooth oil path. This allows for the rapid discharge of oil generated during the operation of the range hood, reducing the amount of oil accumulated in the smoke collection chamber. Attached Figure Description

[0025] 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:
[0026] This utility model discloses a smoke hood. Please refer to [link / reference]. Figures 1 to 4The present invention proposes a range hood comprising a range hood body 1, a smoke exhaust fan 2, an oil receiving component 3, and an oil guiding component 4; the range hood body 1 has a smoke collection chamber 11, which has an oil dripping hole 111; the smoke exhaust fan 2 is disposed in the smoke collection chamber 11, and the bottom of the volute of the smoke exhaust fan 2 is provided with an oil leakage hole; the oil receiving component 3 is disposed in the smoke collection chamber 11 and is used to receive the oil discharged by the smoke exhaust fan 2; the oil guiding component 4 is connected to the oil receiving component 3 and is used to guide the oil on the oil receiving component 3 to the side of the smoke collection chamber 11 where the oil dripping hole 111 is provided.
[0027] In this embodiment, the main body 1 of the range hood is provided with an air intake 112, which is connected to the smoke collection chamber 11. When the exhaust fan 2 is running, the negative pressure generated by the exhaust fan 2 in the smoke collection chamber 11 causes the external airflow to enter the smoke collection chamber 11 through the air intake 112, so that the range hood can normally extract oil fumes.
[0028] The oil receiving component 3 is located below the exhaust fan 2 and above the bottom wall of the smoke collection chamber 11. Specifically, within the smoke collection chamber 11, the oil receiving component 3 is positioned between the exhaust fan 2 and the bottom wall of the smoke collection chamber 11. After long-term operation within the smoke collection chamber 11, oil will accumulate inside the exhaust fan 2. When the oil reaches a certain level, it will drip downwards from the volute of the exhaust fan 2. The oil receiving component 3 can collect the oil dripping from the exhaust fan 2, preventing it from dripping directly out of the air intake 112 or onto the bottom wall of the smoke collection chamber 11.
[0029] After the oil discharged by the exhaust fan 2 drips onto the oil receiving part 3, it can flow along the oil receiving part 3 to the oil guiding part 4, then flow along the oil guiding part 4 to the oil dripping hole 111, and finally be discharged from the smoke collection chamber 11 through the oil dripping hole 111.
[0030] Since the distance between the oil receiving part 3 and the bottom of the volute is less than the distance between the bottom of the volute and the bottom of the smoke collection chamber 11, the oil droplets fall a shorter distance from the bottom of the volute to the oil receiving part 3, accumulating less kinetic energy. Consequently, the splashing after dripping onto the oil receiving part 3 is also less, which can prevent a large amount of oil from splashing when it is discharged from the volute to the oil receiving part 3, thus preventing the oil from soiling the cavity wall of the smoke collection chamber 11 or splashing out of the air intake 112. Furthermore, the oil received by the oil receiving part 3 is discharged through the oil guide part 4 to the side of the smoke collection chamber 11 with the oil dripping hole 111. The oil path is clear and smooth, which can quickly discharge the oil generated during the operation of the range hood and reduce the amount of oil accumulated in the smoke collection chamber 11.
[0031] The smoke hood of this utility model, such as Figures 2 to 4 As shown, the oil receiving component 3 is inclined in the smoke collection chamber 11. The height of the end of the oil receiving component 3 near the oil dripping hole 111 is lower than the height of the end away from the oil dripping hole 111. Oil drain ports 31 are provided on both sides of the end of the oil receiving component 3 near the oil dripping hole 111, and the oil drain ports 31 are connected to the oil guide component 4.
[0032] The oil receiving part 3 is set at an angle to the horizontal direction. The oil dripping on the oil receiving part 3 can flow towards the lower end of the oil receiving part 3 under the action of gravity. When the oil on the oil receiving part 3 flows to the lower end, it can flow to the oil guide part 4 through the oil drain port 31. In this way, the oil on the oil receiving part 3 can flow to the oil guide part 4 in a timely and sufficient manner, so as to prevent the oil from accumulating on the oil receiving part 3.
[0033] The smoke hood of this utility model, such as Figures 2 to 4 As shown, the main body 1 of the range hood has a suction panel 12, on which a suction port 112 is provided. The suction port 112 communicates with the smoke collection chamber 11, and the oil dripping hole 111 is located on the rear side of the suction port 112. The upper surface of the suction panel 12 is the bottom wall of the smoke collection chamber 11. The oil dripping hole 111 can also be provided on the suction panel 12. The range hood also includes an oil cup, which can be installed below the suction panel 12 and communicates with the oil dripping hole 111 to collect the oil discharged through the oil dripping hole 111. Since the oil dripping hole 111 is located on the rear side of the suction port 112, the position of the oil cup is also correspondingly located on the rear side of the suction port 112, thus making the position of the oil cup on the range hood more reasonable.
[0034] The smoke hood of this utility model, such as Figures 1 to 2 As shown, the main body 1 of the smoke hood includes a smoke collection box 1a and an exhaust box 1b. The exhaust box 1b is located above the smoke collection box 1a, and the exhaust fan 2 is located inside the exhaust box 1b. The inner cavity of the smoke collection box 1a and the inner cavity of the exhaust box 1b are connected, forming a smoke collection chamber 11. The bottom plate of the smoke collection box 1a is the suction panel 12, and the cover plate 14 of the smoke collection box 1a has an installation port. The exhaust box 1b opens downwards and connects to the installation port of the smoke collection box 1a. The oil receiving component 3 and the oil guiding component 4 are both installed inside the smoke collection box 1a. The height of the exhaust box 1b is greater than the height of the smoke collection box 1a, while the length and width of the smoke collection box 1a are greater than the length and width of the exhaust box 1b. This allows the size of the exhaust box 1b to be adapted to the size of the exhaust fan 2, and the size of the smoke collection box 1a to be adapted to the size of the oil receiving component 3 and the oil guiding component 4.
[0035] The smoke hood of this utility model, such as Figures 2 to 4 As shown, the smoke collection box 1a is equipped with a bellows support 13. The smoke collection box 1a has a cover plate 14 with an installation port. The exhaust box 1b is installed at the installation port and supported by the bellows support 13. The exhaust box 1b is installed on top of the smoke collection box 1a, so the smoke collection box 1a needs to bear the weight of the exhaust box 1b and the exhaust fan 2. If the cover plate 14 of the smoke collection box 1a is used alone to bear the weight of the exhaust box 1b and the exhaust fan 2, it is easy for the cover plate 14 to deform or be damaged. The bellows support 13 can support the exhaust box 1b and distribute the weight of the exhaust box 1b and the exhaust fan 2 to other parts of the smoke collection box 1a, preventing the smoke collection box 1a from being deformed or damaged due to concentrated force on a single part, thereby improving the overall structural stability of the smoke collection box 1a.
[0036] The smoke hood of this utility model, such as Figures 2 to 4 As shown, the suction panel 12 is provided with a panel reinforcement plate 15. The panel reinforcement plate 15 is provided with a support part on the side near the oil receiving part 3. The higher end of the oil receiving part 3 is connected to the air box bracket 13, and the lower end is connected to the support part of the panel reinforcement plate 15.
[0037] In addition to supporting the exhaust box 1b, the bellows bracket 13 can also be used to connect the oil receiving part 3, thus improving the effective utilization rate of the bellows bracket 13. The end of the oil receiving part 3 away from the bellows bracket 13 is connected to the panel reinforcing plate 15, so that the position of the oil receiving part 3 is higher than the bottom plate of the smoke collection chamber 11.
[0038] The smoke hood of this utility model, such as Figures 2 to 4 As shown, the smoke collection chamber 11 is also provided with an oil baffle 5. The projection of the cover plate 14 onto the suction panel 12 has a portion that is aligned with the suction port 112. At least this portion of the projection of the cover plate 14 onto the suction panel 12 falls onto the oil baffle 5, and the projection of the oil baffle 5 onto the suction panel 12 at least covers this portion of the suction port 112.
[0039] Part of the cover plate 14 is directly opposite a part of the air intake 112. The area directly opposite the cover plate 14 and the air intake 112 can be defined as the opposing area. The oil-blocking component 5 is located between the opposing area of the cover plate 14 and the air intake 112. After the fumes enter the smoke collection chamber 11 from the air intake 112, the fumes rushing towards the opposing area of the cover plate 14 are blocked by the oil-blocking component 5, thus preventing the fumes from directly adhering to the cover plate 14. If oil flows from other locations to the opposing area of the cover plate 14 and drips, the dripping oil can also be caught by the oil-blocking component 5, thus preventing oil droplets from dripping from the air intake 112 to the outside of the smoke collection chamber 11. This ensures the cleanliness of the stovetop, prevents the range hood from affecting the hygiene of the kitchen, and improves the performance of the range hood.
[0040] The smoke hood of this utility model, such as Figures 2 to 4 As shown, the oil baffle 5 is inclined, with the height of its front end lower than the height of its rear end, and the oil on the oil baffle 5 is discharged through the lower end.
[0041] The surface of the oil baffle 5 is set at an angle to the front and rear directions. The oil dripping on the oil baffle 5 can flow towards the lower edge of the oil baffle 5 under the action of gravity, so that the oil on the oil baffle 5 can flow away more timely and fully, and avoid the accumulation of oil on the oil baffle 5.
[0042] In this utility model of a range hood, the oil-blocking component 5 is inclined, and an oil-resistant coating is provided on the wall surface of the side of the oil-blocking component 5 facing the air intake 112. Since the side of the oil-blocking component 5 facing the air intake 112 is easily exposed to the user's view through the air intake 112, the oil-resistant coating on this side of the oil-blocking component 5 prevents oil fumes from adhering to the oil-blocking component 5 during operation, keeping it clean and improving the user's visual experience when looking at the oil-blocking component 5 from the air intake 112.
[0043] The smoke hood of this utility model, such as Figures 2 to 4 As shown, the front end of the oil baffle 5 is connected to the oil receiving part 3, and the rear end of the oil baffle 5 is connected to the rear wall of the smoke collecting chamber 11; or the rear end of the oil baffle 5 extends to a connecting part 51, which extends toward the rear wall of the smoke collecting chamber 11 and connects to the rear wall of the smoke collecting chamber 11.
[0044] The oil-blocking component 5 is located behind the oil-receiving component 3. The front end of the oil-blocking component 5 is connected to the rear end of the oil-receiving component 3, and the rear end of the oil-blocking component 5 is directly connected to the rear wall of the smoke collection chamber 11, or indirectly connected to the rear wall of the smoke collection chamber 11 through the connecting part 51. In this way, the oil-blocking component 5 can be suspended between the bottom wall of the smoke collection chamber 11 and the cover plate 14 with the help of the oil-receiving component 3, so as to improve the effective utilization rate of the oil-receiving component 3 and make the internal structure of the smoke machine body 1 more stable and compact.
[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
