[0028] 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:
[0029] This utility model discloses a smoke hood. Please refer to [link / reference]. Figures 1 to 6 The range hood proposed in this utility model includes a range hood body 1, the range hood body 1 has a suction panel 11, the suction panel 11 is provided with a suction port 12, the suction port 12 is narrow and long, the suction port 12 is arranged along the width direction of the suction panel 11, and a connecting member is provided on one / both sides of the length direction or / and both sides of the width direction of the suction port 12, the connecting member is used for guiding air and / or guiding oil.
[0030] In this embodiment, the main body 1 of the range hood is provided with a smoke collection chamber, and a smoke exhaust fan is installed in the smoke collection chamber. The air intake 12 is connected to the smoke collection chamber. When the smoke exhaust fan is running, the negative pressure generated by the smoke exhaust fan in the smoke collection chamber causes the external airflow to enter the smoke collection chamber through the air intake 12, so that the range hood can normally extract oil fumes.
[0031] The range hood can be either a top-mounted or side-mounted type.
[0032] If the range hood is a top-mounted range hood, the suction panel 11 extends horizontally, and the opening direction of the suction port 12 is vertically downward. At this time, the two ends of the length direction and both sides of the width direction of the suction port 12 are provided with connectors. The connectors can guide the airflow through the suction port 12 and prevent the oil on the suction panel 11 from flowing from the periphery of the suction port 12 to the suction port 12, so as to prevent the oil from dripping out of the range hood from the suction port 12.
[0033] If the range hood is a side-draft type, the suction panel 11 extends backward and upward from bottom to top, and the opening of the suction port 12 is tilted upward and forward. At this time, the oil on the suction panel 11 will flow downward along the inner wall of the suction panel 11. When the oil flows through the upper edge or both ends of the suction port 12, it is easy to drip out of the range hood from the suction port 12. Therefore, the connector can be provided only at the upper edge of the suction port 12, or at the upper edge and both ends of the suction port 12. The connector can guide the airflow through the suction port 12 and prevent the oil on the suction panel 11 from flowing out of the suction port 12 from the upper edge or both ends of the suction port 12, thus preventing the oil from dripping out of the range hood from the suction port 12.
[0034] Therefore, depending on the different ways the range hood draws in oil fumes, the connectors can be placed in the corresponding positions to adapt to different types of range hoods. This not only improves the effective utilization rate of the connectors but also ensures the connectors' ability to prevent oil spillage.
[0035] The smoke hood of this utility model, such as Figures 4 to 5 As shown, the connector includes a first connector 2 located at both ends of the air intake 12 along its length. The first connector 2 includes a connecting part 21 and an oil-blocking part 22. The connecting part 21 is connected to the inner surface of the air intake panel 11. The first edge a of the connecting part 21 facing the air intake 12 is adapted to the contour of the second edge b of the air intake 12 and is arranged around the second edge b. The oil-blocking part 22 protrudes from the surface of the connecting part 21 and is arranged around the first edge a. The surface between the oil-blocking part 22 and the first edge a forms an oil-guiding surface. The oil-guiding surface is used to guide the oil to the side of the range hood body 1 where the oil dripping hole is located.
[0036] The second edge b of the air intake 12 is arc-shaped, and the first edge a of the connecting part 21 is also arc-shaped. The range hood also includes an oil cup, which can be installed below the air intake panel 11 and communicates with the oil drip hole to collect the oil discharged through the oil drip hole.
[0037] If the range hood is a top-mounted type, the oil drip hole can be located on the rear side of the air intake 12 so that the position of the oil cup is also located on the rear side of the air intake 12, thus making the position of the oil cup on the range hood more reasonable.
[0038] If the range hood is a side-suction type, the oil drip hole can be located below the air intake 12 so that the oil cup is also located below the air intake 12, thus making the position of the oil cup on the range hood more reasonable.
[0039] The oil guiding surface is used to guide the oil flowing through the oil blocking part 22 to the rear side of the range hood air intake 12, so that the oil can eventually flow into the oil cup from the oil drip hole.
[0040] The smoke hood of this utility model, such as Figures 4 to 5As shown, the edge of the air intake 12 is provided with a flange, which is located inside the air intake panel 11. The flange forms a constricted shape, and one end of the flange away from the edge of the air intake 12 extends into the air intake 12. The flange includes first flanges 121 located on both sides of the length direction of the air intake 12. A first oil guide groove is formed between the first flanges 121 and the corresponding oil baffles 22. The first oil guide groove can play a role in converging and guiding the oil, and the first flanges 121 can prevent the oil in the first oil guide groove from flowing out of the air intake 12.
[0041] The smoke hood of this utility model, such as Figures 4 to 5 As shown, the bottom surface of the connecting part 21 is provided with a mating structure 23 that is adapted to the flange in the width direction of the air intake 12. The mating structure 23 is connected to the first flange 121 on the corresponding side. The first flange 121 protrudes from the upper surface of the air intake panel 11. The mating structure 23 of the connecting part 21 is fastened to the first flange 121, so that the first flange 121 can play a positioning role for the first connector 2, preventing the first connector 2 from easily shifting, and improving the connection stability between the first connector 2 and the air intake panel 11.
[0042] The smoke hood of this utility model, such as Figure 2 , Figure 3 and Figure 6 As shown, a panel reinforcement plate 3 is connected to the suction panel 11. The panel reinforcement plate 3 avoids the suction port 12. The suction port 12 has a first side close to the oil drip hole on the main body 1 and a second side away from the oil drip hole on the main body 1 along the width direction. The connector also includes an extension plate 31 provided on the first side / both sides of the panel reinforcement plate 3 close to the suction port 12. The extension plate 31 is used to guide the oil to the side of the main body 1 where the oil drip hole is provided.
[0043] The panel reinforcement plate 3 has a clearance opening that avoids the air intake 12, so that the panel reinforcement plate 3 surrounds the air intake 12. The panel reinforcement plate 3 can improve the structural strength of the air intake panel 11 around the air intake 12 and prevent the air intake panel 11 from being easily deformed or damaged after the connectors are installed.
[0044] If the range hood is a top-mounted range hood, there are two extension plates 31. The two extension plates 31 are respectively connected to the two long edges of the clearance opening. The distance between the two extension plates 31 and the suction panel 11 decreases from the side where the two extension plates 31 are close to each other to the side where they are far apart, so that the two extension plates 31 are tilted upwards.
[0045] If the range hood is a side-suction type, there is one extension plate 31. The extension plate 31 is connected to the long edge of the avoidance opening near the oil drip hole to guide the oil to the oil drip hole.
[0046] The smoke hood of this utility model, such as Figure 2 , Figure 3 and Figure 6As shown, the edge of the air intake 12 is provided with a flange, which is located inside the air intake panel 11. The flange forms a constricted shape, and one end of the flange away from the edge of the air intake 12 extends into the air intake 12. The flange includes a second flange 122 located on both sides of the air intake 12 along the width direction. A second oil guide groove is formed between the second flange 122 and the extension plate 31 on the corresponding side. The second oil guide groove is used to guide the oil to the side of the range hood body 1 where the oil drip hole is provided.
[0047] There are two second flanges 122, which are respectively connected to the two long edges of the air intake 12. The distance between the two second flanges 122 and the air intake panel 11 decreases from the side where the two second flanges 122 are close to each other to the side where they are far apart, so that the two second flanges 122 are tilted upwards. The second flanges 122 can prevent the oil in the second oil guide groove from flowing to the air intake 12, thereby preventing the air intake 12 from dripping oil onto the outside of the range hood.
[0048] The second flange 122 can strengthen the opening of the air intake 12 and improve its strength. When the fumes are drawn upward from the air intake 12, the air intake 12, which has a constricted structure formed by the second flange 122, increases the speed of the fumes as they are discharged from the air intake 12, thereby enhancing the system's air intake efficiency.
[0049] The smoke hood of this utility model, such as Figure 3 and Figure 6 As shown, an oil guide hole 311 is formed on the extension plate 31 of the panel reinforcing plate 3 on the first side near the air intake 12. The oil guide hole 311 allows oil in the second oil guide groove to flow out, preventing excessive accumulation of oil in the second oil guide groove and subsequent overflow and dripping out of the air intake 12. Multiple oil guide holes 311 can be provided, spaced apart along the length of the extension plate 31 to increase the available positions for oil to flow out of the second oil guide groove, ensuring timely and sufficient drainage of the oil. By placing the oil guide hole 311 on the extension plate 31 on the first side near the air intake 12, the oil can flow directly to the drip hole after exiting the oil guide, thus improving the oil drainage effect.
[0050] The smoke hood of this utility model, such as Figure 3 and Figure 6 As shown, one end of the extension plate 31 is connected to the panel reinforcement plate 3, and the other side of the extension plate 31 extends toward the edge of the air intake 12. The projection of the air intake panel 11 on the other side of the extension plate 31 falls outside the edge of the corresponding side of the air intake 12. In this way, the extension plate 31 can prevent the airflow path into the air intake 12 from being blocked, so as to ensure the stability of the airflow velocity and the flow field when the airflow passes through the air intake 12.
[0051] The smoke hood of this utility model, such as Figure 3 and Figure 6As shown, an air guide plate 32 is provided on the extension plate 31, and the air guide plate 32 extends in a direction away from the corresponding side edge of the air intake 12. There are two air guide plates 32, which are respectively connected to the upper edges of the two extension plates 31. The distance between the two air guide plates 32 increases from the side closer to the air intake 12 to the side away from the air intake 12. In this way, a wide-mouthed air guide channel is formed between the two air guide plates 32. The airflow flowing into the air intake 12 can diffuse more quickly when it flows through the air guide channel, reducing the turbulence of the airflow above the air intake 12 caused by the extension plate 31, thereby improving the airflow rate and airflow stability of the air intake 12.
[0052] The smoke hood of this utility model, such as Figure 3 As shown, the edge of the air intake 12 is provided with a flange, which is located inside the air intake panel 11. The flange forms a constricted shape, and one end of the flange away from the edge of the air intake 12 extends into the air intake 12. The flange includes two first flanges 121 located in the width direction of the air intake 12 and two second flanges 122 located in the length direction of the air intake 12. The upper edge of the second flange 122 is provided with a folded edge, which is folded downward and abuts against the inner wall of the second flange 122.
[0053] There are two folded edges, which are respectively connected to the upper edges of the two second flanges 122. The formation of the folded edges can further strengthen the opening of the air intake 12 and improve the structural strength of the opening. The lower edges of the folded edges form a blocking structure, which can reduce the possibility of oil from the bottom of the second oil guide groove spreading upward along the second flanges 122 and entering the air intake 12.
[0054] 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.
