Description

Technical Field

[0001] This utility model relates to the field of smoke hood technology, specifically to a smoke hood. Background Technology

[0002] Range hoods include top-mounted and side-mounted models. Regardless of whether it's top-mounted or side-mounted, the inner wall of the cover plate of the range hood has a part that aligns with the air intake. When the range hood is working for a long time, after the fumes enter the range hood from the top air intake, some of the fumes will accumulate on the part of the cover plate that is directly opposite the top air intake. This causes the oil to adhere and accumulate on this part of the cover plate, forming grease. Over time, the grease can easily gather and drip off, causing the oil droplets to drip directly from the top air intake and fall onto the stovetop, affecting the performance of the range hood. Furthermore, when users can see the grease on the part of the smoke collection chamber that is directly opposite the air intake through the air intake, it affects the appearance of the range hood.

[0005] According to one embodiment of the present invention, the oil baffle is inclined, and the projections of the front and rear edges of the oil baffle onto the suction panel are all located outside the suction port.

[0006] According to one embodiment of the present invention, the main body of the range hood has an oil guide hole for discharging oil from the smoke collection chamber, and the height of the side of the oil baffle plate facing the oil guide hole is lower than the height of the side away from the oil guide hole.

[0007] According to one embodiment of the present invention, the main body of the range hood has an oil guide hole, which is located behind the air intake in the front-to-back direction, and the oil baffle is inclined downward from front to back.

[0008] According to one embodiment of the present invention, the oil baffle plate has oil-blocking edges on both sides in the left and right directions, and the oil-blocking edges ensure that the oil dripping onto the oil baffle plate can only be discharged from the front and / or rear edges of the oil baffle plate.

[0009] According to one embodiment of the present invention, the oil baffle is inclined, and a connecting plate extends from the lower end of the oil baffle towards the wall of the corresponding side of the smoke collection chamber. The connecting plate is connected to the wall of the corresponding side of the smoke collection chamber.

[0010] According to one embodiment of the present invention, a reinforcing plate extends from the connecting plate away from the air intake.

[0011] According to one embodiment of the present invention, a smoke exhaust fan is also provided in the smoke collection chamber, and an oil receiving component is also provided in the smoke collection chamber.

[0024] 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:

[0025] This utility model discloses a smoke hood. Please refer to [link / reference]. Figures 1 to 3 The range hood proposed in this utility model includes a range hood body 1 and an oil baffle plate 2. The range hood body 1 has an air intake panel 11 and a smoke collection chamber 12 located inside the air intake panel 11. The air intake panel 11 is provided with an air intake 111, which is connected to the smoke collection chamber 12. The oil baffle plate 2 is located inside the smoke collection chamber 12. The projection of the cover plate 121 of the smoke collection chamber 12 onto the air intake panel 11 has a portion that overlaps with the air intake 111. At least this portion of the projection of the cover plate 121 onto the air intake panel 11 falls into the oil baffle plate 2. The wall surface of the oil baffle plate 2 facing the air intake 111 is provided with an oil-resistant coating.

[0026] In this embodiment, the cover plate 121 is provided with a connection port for connecting to the air collection box located above the cover plate 121. The air collection box is connected to the smoke collection chamber 12, and an exhaust fan 3 is installed inside the air collection box. The cover plate 121 is located above the top plate, that is, above the air intake 111. The width of the air intake 111 in the left-right direction is greater than the width of the connection port, so the air intake 111 is directly opposite the cover plate 121. The area where the cover plate 121 and the air intake 111 are directly opposite can be defined as the directly opposite area. The oil baffle 2 is located between the directly opposite area of ​​the cover plate 121 and the air intake 111.

[0027] The air intake 111 is connected to the smoke collection chamber 12. When the exhaust fan 3 is running, the negative pressure generated by the exhaust fan 3 in the smoke collection chamber 12 causes external airflow to enter the smoke collection chamber 12 through the air intake 111, thus allowing the range hood to normally extract cooking fumes. After the cooking fumes enter the smoke collection chamber 12, the fumes rushing towards the area directly opposite the cover plate 121 are blocked by the oil baffle 2, thus preventing the fumes from directly adhering to the cover plate 121. If oil flows from other locations to the area directly opposite the cover plate 121 and drips, the dripping oil can also be caught by the oil baffle, thus preventing oil droplets from dripping from the air intake 111 to the outside of the smoke collection chamber 12, thereby ensuring the cleanliness of the stovetop, preventing the range hood from affecting the hygiene of the kitchen, and improving the performance of the range hood. An anti-oil coating is applied to the side wall of the oil baffle 2 facing the air intake 111. When the range hood is running, the oil fumes enter the smoke collection chamber 12 through the air intake 111. The oil fumes are not easy to adhere to the oil baffle 2, keeping the oil baffle 2 clean, thereby improving the visual experience of the user when looking at the oil baffle 2 from the air intake 111.

[0028] The smoke hood of this utility model, such as Figures 1 to 3 As shown, the oil baffle 2 is inclined, and the projections of the front and rear edges of the oil baffle 2 onto the suction panel 11 are all located outside the suction port 111.

[0029] The projection of the oil baffle 2 onto the suction panel 11 in the front-to-back direction is larger than the front-to-back direction of the suction port 111, and the suction port 111 is located between the front and back edges of the projection of the oil baffle 2 onto the suction panel 11. In this way, the projection of the oil baffle 2 onto the suction panel 11 can completely cover the suction port 111 in the front-to-back direction, thereby fully catching the oil dripping from above the oil baffle 2 onto the suction port 111. The surface of the oil baffle 2 is set at an angle to the front and back direction. The oil dripping on the oil baffle 2 can flow towards the lower edge of the oil baffle 2 under the action of gravity. Since the projections of the front and back edges of the oil baffle 2 on the suction panel 11 are located in front of and behind the suction port 111 respectively, when the oil flows to the lowest edge of the oil baffle 2, it leaves the area directly above the suction port 111. At this time, even if the oil leaves the oil baffle 2 and drips downward, it will not drip out of the suction port 111, thereby improving the effect of preventing oil from dripping out of the suction port 111.

[0030] The smoke hood of this utility model, such as Figures 1 to 3 As shown, the main body 1 of the range hood has an oil guide hole 13, which is used to discharge the oil in the smoke collection chamber 12. The height of the side of the oil baffle 2 facing the oil guide hole 13 is lower than the height of the side away from the oil guide hole 13. The oil guide hole 13 is located near the lowest edge of the oil baffle 2. When the oil on the oil baffle 2 flows to the lowest edge, it can continue to flow into the oil guide hole 13 and then be discharged from the smoke collection chamber 12 through the oil guide hole 13. This achieves the guidance and discharge of the oil on the oil baffle 2, preventing the oil from accumulating everywhere in the smoke collection chamber 12.

[0031] The smoke hood of this utility model, such as Figures 1 to 3 As shown, the main body 1 of the range hood has an oil guide hole 13, which is located behind the air intake 111 in the front-to-back direction. The oil baffle 2 is inclined downward from front to back. The highest side of the oil baffle 2 is located in front of the air intake 111, and the lowest side of the oil baffle 2 is located behind the air intake 111. The oil dripping on the oil baffle 2 flows downward and backward, and after flowing to the lowest side of the oil baffle 2, it is discharged into the smoke collection chamber 12 through the oil guide hole 13. The range hood also includes an oil cup, which can be installed below the air intake panel 11 and communicates with the oil guide hole 13 to collect the oil discharged through the oil guide hole 13. Since the oil guide hole 13 is located behind the air intake 111, the position of the oil cup is also correspondingly located behind the air intake 111, thus making the position of the oil cup on the range hood more reasonable.

[0032] The smoke hood of this utility model, such as Figures 1 to 3 As shown, the oil baffle 2 has oil-blocking edges 21 on both sides in the left and right directions. The oil-blocking edges 21 ensure that oil dripping onto the oil baffle 2 can only be discharged from the front and / or rear edges of the oil baffle 2. The oil-blocking edges 21 can block the oil flowing towards the left and right edges of the oil baffle 2, preventing the oil from dripping down from the left and right edges of the oil baffle 2, thus ensuring that the oil can only be discharged from the front and / or rear edges of the oil baffle 2, and ensuring that the oil leaves the area directly above the air intake 111 when it leaves the oil baffle 2.

[0033] The smoke hood of this utility model, such as Figures 1 to 3 As shown, the oil baffle 2 is inclined, and a connecting plate 22 extends from the lower end of the oil baffle 2 toward the wall of the corresponding side of the smoke collection chamber 12. The connecting plate 22 is connected to the wall of the corresponding side of the smoke collection chamber 12.

[0034] Taking the oil baffle 2 as an example of being inclined downwards from front to back, one end of the connecting plate 22 is connected to the rear edge of the oil baffle 2, and the other end is connected to the rear cavity wall of the smoke collection chamber 12. In this way, the oil baffle 2 can be indirectly connected to the cavity wall of the smoke collection chamber 12, so as to realize the installation of the oil baffle 2 between the air intake 111 and the cover plate 121, thereby improving the installation stability of the oil baffle 2.

[0035] The smoke hood of this utility model, such as Figures 1 to 3 As shown, a reinforcing plate 221 extends from the connecting plate 22 away from the air intake 111. The reinforcing plate 221 can improve the structural strength of the connecting plate 22 and prevent the connecting plate 22 from being easily deformed or damaged, thereby improving the connection stability between the oil baffle plate 2 and the wall of the smoke collection chamber 12.

[0036] The smoke hood of this utility model, such as Figures 1 to 3 As shown, an exhaust fan 3 is also installed inside the smoke collection chamber 12, and an oil receiving component 4 is also installed inside the smoke collection chamber 12. The oil receiving component 4 is located below the exhaust fan 3 and is used to collect the oil discharged from the volute of the exhaust fan 3. After long-term operation in the smoke collection chamber 12, oil will accumulate inside the exhaust fan 3. When the oil accumulates to a certain extent, it will drip down from the volute of the exhaust fan 3. The oil receiving component 4 can collect the oil dripping from the exhaust fan 3, preventing the oil from dripping directly out of the air intake 111 or onto the air intake panel 11, thereby further improving the oil leakage prevention effect of the range hood.

[0037] The smoke hood of this utility model, such as Figures 1 to 3 As shown, the bottom of the smoke collection chamber 12 is provided with an oil guide hole 13, and the oil receiving component 4 is inclined. The height of the side of the oil receiving component 4 that is closer to the oil guide hole 13 is lower than the height of the side that is farther away from the oil guide hole 13. The lower end of the oil receiving component 4 is provided with oil outlets 41 on both sides. Each oil outlet 41 is connected to an oil guide groove 5. The oil guide groove 5 extends around the corresponding side air intake 111 and extends to the side of the smoke collection chamber 12 where the oil guide hole 13 is provided.

[0038] The surface of the oil receiving part 4 is set at an angle to the front-to-back direction. The oil dripping onto the oil receiving part 4 can flow towards the lower edge of the oil receiving part 4 under the action of gravity. The oil guide hole 13 is close to the lowest edge of the oil receiving part 4. When the oil on the oil receiving part 4 flows to the lowest edge, it can flow through the oil drain 41 to the oil guide groove 5, and then along the oil guide groove 5 to the oil guide hole 13, and finally be discharged from the smoke collection chamber 12 through the oil guide hole 13. When the oil guide groove 5 extends towards the oil guide hole 13, it bypasses the left and right ends of the air intake 111. That is, the projection of the part of the oil guide groove 5 extending towards the oil guide hole 13 on the air intake panel 11 is located on the left or right side of the air intake 111. Therefore, the flow path of the oil flowing along the oil guide groove 5 will also bypass the left and right ends of the air intake 111. In this way, the flow path of the oil can avoid the area directly above the air intake 111, so as to prevent the oil from splashing and dripping out of the air intake 111 during the flow.

[0039] The smoke hood of this utility model, such as Figures 1 to 3As shown, the exhaust fan 3 is tilted, and the projection of the exhaust fan 3 onto the suction panel 11 covers the part of the suction port 111 that is not blocked by the oil baffle 2. The exhaust fan 3 is located directly above the suction port 111, and the suction side of the exhaust fan 3 is tilted downwards from front to back towards the suction port 111. The oil baffle 2 is not located between the exhaust fan 3 and the suction port 111, so the negative pressure generated by the exhaust fan 3 at the suction port 111 is not affected by the oil baffle 2, thus ensuring the suction effect of the exhaust fan 3 on the oil fumes.

[0040] 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.
