[0043] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0044] The following describes in detail the overall structure, working principle, and technical effects of the range hood 010 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0045] Please refer to Figure 1 The range hood 010 provided by this utility model is applied to top-mounted range hoods 010 and side-mounted range hoods 010.

[0046] Please refer to Figure 1 This utility model provides a range hood 010, including a smoke collection hood 200. The smoke collection hood 200 forms a smoke collection chamber inside. The smoke collection hood 200 is provided with a first air inlet 201 and a second air inlet 202. The first air inlet 201 and the second air inlet 202 are used to connect the smoke collection chamber with the outside. The first air inlet 201 is located near the front side of the smoke collection hood 200, and the second air inlet 202 is located near the rear side of the smoke collection hood 200. The air intake area of ​​the first air inlet 201 is larger than the air intake area of ​​the second air inlet 202.

[0047] The front side of the smoke hood 200 is provided with a rotatable smoke baffle 300, which is used to open or close the first air inlet 201.

[0048] The "external" part can be understood as the location where the range hood 010 is installed.

[0049] Understandably, when a user is cooking with a large amount of oil fumes, opening the baffle 300 on the front of the fume hood 200 allows most of the oil fumes to enter the fume collection chamber through the first air inlet 201, blocked by the baffle 300. The remaining oil fumes enter the fume collection chamber through the second air inlet 202 located at the rear. This ensures that the range hood 010 has a good oil fume extraction effect. After cooking, closing the baffle 300 and blocking the first air inlet 201 prevents the oil fumes in the fume collection chamber from escaping.

[0050] When users are steaming or boiling, which produces a small amount of oil fumes, they do not need to open the smoke baffle 300; the fan assembly starts, and the oil fumes generated during steaming or boiling can enter the smoke collection chamber through the second air inlet 202; this not only makes it convenient for users and saves energy, but also absorbs the oil fumes or odors generated during steaming or boiling.

[0051] Therefore, this application, by setting up a smoke baffle 300, a first air inlet 201, and a second air inlet 202, allows the smoke baffle 300 to open or close the first air inlet 201, enabling users to use the first air inlet 201 and the second air inlet 202 according to different needs. This provides users with more selectable modes, a better experience, and energy savings. Furthermore, by setting up the first air inlet 201 and the second air inlet 202, the two air inlets can increase the overall air intake area and smoke extraction effect of the range hood 010. Moreover, by setting up the smoke baffle 300, which can open or close the first air inlet 201, the baffle can prevent the oil fumes in the smoke collection chamber from escaping, avoiding odors in the kitchen.

[0052] In this embodiment, the range hood 010 includes a housing 100.

[0053] Please refer to Figure 1 The housing 100 is located on top of the smoke collection hood 200 and is connected to the smoke collection chamber. The housing 100 contains a fan assembly for absorbing oil fumes.

[0054] In this embodiment, the range hood 010 includes a smoke collection hood 200.

The smoke baffle 300 is located at the bottom of the panel 210 and is rotatable relative to the panel 210.

[0056] In this embodiment, the first air inlet 201 includes multiple first air inlets 201, which are arranged along the front-to-back direction and spaced apart along the left-to-right direction; the second air inlet 202 includes one, and the first air inlet 201 is arranged along the left-to-right direction; so that the air intake area of ​​the first air inlet 201 is larger than the air intake area of ​​the second air inlet 202.

[0057] Understandably, when a user is cooking with a large amount of oil fumes, the baffle plate 300 on the front of the fume hood 200 is opened; the fan assembly is started, and most of the oil fumes enter the fume collection chamber from the first air inlet 201 under the obstruction of the baffle plate 300, while the remaining oil fumes enter the fume collection chamber from the second air inlet 202 located at the rear; thus ensuring that the range hood 010 has a good oil fume extraction effect.

[0058] When users are steaming or boiling, which produces a small amount of oil fumes, they do not need to open the smoke baffle 300; the fan assembly starts, and the oil fumes generated during steaming or boiling can enter the smoke collection chamber through the second air inlet 202; this not only makes it convenient for users and saves energy, but also absorbs the oil fumes or odors generated during steaming or boiling.

[0059] In this embodiment, please refer to Figure 5 The panel 210 has a first flange 215 along the edge of the first air inlet 201 facing the smoke collection chamber, please refer to...

[0062] The oil guide hole 213 is located on the rear side of the panel 210 relative to the second air inlet 202.

[0063] Understandably, the panel 210 is inclined along the horizontal plane, which can better guide the oil droplets gathered at the top of the panel 210 into the oil cup 230.

[0064] In this embodiment, please refer to Figure 2 The panel 210 has a groove 211, and the first air inlet 201 is located in the groove 211. The groove 211 is used to install the smoke baffle 300 so that when the smoke baffle 300 closes the first air inlet 201, the smoke baffle 300 is flush with the panel 210.

[0065] Understandably, when the smoke baffle 300 is in the state of closing the first air inlet 201, the smoke baffle 300 is installed in the groove 211, and the bottom surface of the smoke baffle 300 is flush with the bottom surface of the panel 210, making the appearance of the range hood 010 more neat and beautiful.

[0066] In this embodiment, please refer to Figure 2 The panel 210 is provided with a magnetic part 214 located in the groove 211, which is used to magnetically connect with the smoke baffle 300.

[0067] Optionally, at least two magnetic suction parts 214 are provided, with the two magnetic suction parts 214 located on the left and right sides of the plurality of first air inlets 201 respectively, so as to achieve a stable magnetic connection to the smoke baffle 300.

[0068] Alternatively, if the magnetic part 214 can be a magnet, then the smoke baffle 300 can be made of metal.

[0069] In this embodiment, please refer to Figure 2 The smoke baffle 300 has rotating arm structures 310 on both its left and right sides. One end of the rotating arm structure 310 is connected to the smoke baffle 300, and the other end is connected to the smoke collection hood 200. Please refer to... Figures 3-4 The smoke hood 200 is equipped with a drive structure 320, which drives any one of the rotating arm structures 310 to open or close the first air inlet 201.

[0070] In this embodiment, please refer to Figures 2-4 The panel 210 has sliding grooves 212 on the left and right sides of the first air inlet 201; the rotating arm structure 310 includes an opening and closing arm 311, a first connecting seat 312 and a second connecting seat 313; the first connecting seat 312 is connected to one side of the smoke baffle 300, the second connecting seat 313 is connected to the top shell 220, the opening and closing arm 311 passes through the sliding groove 212, and one end of the opening and closing arm 311 is connected to the first connecting seat 312, and the other end is rotatably connected to the second connecting seat 313; the drive structure 320 is connected to the opening and closing arm 311 in a transmission manner.

[0071] The sliding groove 212 also has a flange facing the top of the panel 210.

[0072] In this embodiment, please refer to Figures 3-4 The drive structure 320 includes a drive member 321, a first rotating arm 323, and a second rotating arm. The output shaft 322 of the drive member 321 is connected to the first rotating arm 323. One end of the second rotating arm is connected to the first rotating arm 323, and the other end is connected to the opening and closing arm 311. The drive member 321 is used to drive the first rotating arm 323 to rotate, so that the first rotating arm 323 drives the opening and closing arm 311 of the rotating arm structure 310 to rotate through the second rotating arm.

[0073] Optionally, the drive unit 321 can be a drive motor.

[0074] Optionally, the opening and closing arm 311 has a first end, a second end, and a third end connected to each other, wherein the first end and the third end are arranged at an included angle; the first end of the opening and closing arm 311 is connected to the first connecting seat 312 through a connector, the second end is rotatably connected to one end of the second rotating arm through a threaded part, and the third end is rotatably connected to the second connecting seat 313 through a connector.

[0075] Understandably, the output shaft 322 of the drive unit 321 drives the first rotating arm 323 to rotate, the first rotating arm 323 drives the second rotating arm, the second rotating arm drives the second end of the opening and closing arm 311, thereby making the opening and closing arm 311 rotate with the third end rotatably connected to the second connecting seat 313 as the fulcrum, so as to drive the opening and closing arm 311 to rotate, thereby making the opening and closing arm 311 drive the smoke baffle 300 to be rotatably set relative to the panel 210, and to open and close the first opening.

[0076] In one embodiment, a plurality of first air inlets 201 are integrally formed on the panel 210.

[0077] In one embodiment, the smoke hood 200 further includes at least one air inlet plate 240, the panel 210 has at least one mounting port 217 and a second air inlet 202, the at least one air inlet plate 240 has a plurality of first air inlets 201, and the at least one air inlet plate 240 is detachably disposed at at least one mounting port 217.

[0078] Alternatively, please refer to Figure 7 If an assembly port 217 is provided on the panel 210, the air inlet plate 240 can be detachably installed at the assembly port 217 via a connector.

[0079] Alternatively, please refer to Figure 8 If the panel 210 has two or three equal number of mounting ports 217 in the left and right directions, then the number of air inlet plates 240 is the same as the number of mounting ports 217. Each mounting port 217 can be detachably equipped with an air inlet plate 240.

[0080] The working principle and process of the range hood 010 provided in this embodiment of the utility model are as follows:

[0081] First, when the user is cooking with a large amount of oil fumes, the drive unit 321 drives the first rotating arm 323 to rotate, so that the first rotating arm 323 drives the opening and closing arm 311 to rotate relative to the panel 210 through the second rotating arm, and opens the smoke baffle 300 on the front side of the smoke collection hood 200.

[0082] When the fan assembly starts, most of the oil fumes are blocked by the baffle plate 300 and enter the smoke collection chamber through the first air inlet 201. The remaining oil fumes enter the smoke collection chamber through the second air inlet 202 located at the rear. This ensures that the range hood 010 has a good oil fume extraction effect.

[0083] After cooking is finished, the drive unit 321 drives the first rotating arm 323 to rotate, so that the first rotating arm 323 drives the opening and closing arm 311 to rotate relative to the panel 210 through the second rotating arm, so that the smoke baffle 300 closes the first air inlet 201, thereby preventing the oil fumes in the smoke collection chamber from escaping.

[0084] Secondly, when users are steaming or boiling, which produces a small amount of oil fumes, they do not need to open the smoke baffle 300; the fan assembly starts, and the oil fumes generated during steaming or boiling can enter the smoke collection chamber through the second air inlet 202; this not only makes it convenient for users and saves energy, but also absorbs the oil fumes or odors generated during steaming or boiling.

[0085] In summary, the range hood 010 provided in this embodiment of the present invention, by setting a smoke baffle 300, a first air inlet 201, and a second air inlet 202, allows the smoke baffle 300 to open or close the first air inlet 201, enabling users to use the first air inlet 201 and the second air inlet 202 according to different needs. This provides users with more selectable modes, a better experience, and energy savings. Furthermore, by setting the first air inlet 201 and the second air inlet 202, the two air inlets can increase the overall air intake area and smoke extraction effect of the range hood 010. The smoke baffle 300, which can open or close the first air inlet 201, prevents the oil fumes in the smoke collection chamber from escaping, thus avoiding odors in the kitchen.

[0086] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
