[0035] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0036] Please refer to Figure 1-Figure 5The present invention provides a range hood, comprising a smoke hood 3 and a body structure 5 arranged on the upper side of the smoke hood 3, wherein a first air inlet and a second air inlet are provided on the bottom side of the smoke hood 3, a first oil net 11 is provided at the first air inlet, and a second oil net 12 is provided at the second air inlet, and an oil filter structure 2 is also provided. The oil filter structure 2 is provided in a chamber between the smoke hood 3 and the body structure 5, and the oil filter structure 2 includes an oil filter plate provided above the first oil net 11 and the second oil net 12, the oil filter plate including a first filter plate 201 and a second filter plate 202 connected to the first filter plate 201, a first mesh group 23 is provided on the first filter plate 201, and a second mesh group 24 is provided on the second filter plate 202, the first mesh group 23 is located above the first oil net 11, and the second mesh group 24 is located above the second oil net 12. The noise reduction structure includes a first noise reduction component 421 and a second noise reduction component 422. Noise reduction grooves 40 are provided on the first noise reduction component 421 and the second noise reduction component 422. The first noise reduction component 421 is installed on the upper side of the first filter plate 201 and covers the first mesh group 23. The noise reduction groove 40 of the first noise reduction component 421 is set toward the first mesh group 23. The second noise reduction component 422 is installed on the upper side of the second filter plate 202 and covers the second mesh group 24. The noise reduction groove 40 of the second noise reduction component 422 is set toward the second mesh group 24.

[0037] The range hood provided by the present invention comprises an oil filter plate disposed above the first oil net 11 and the second oil net 12, and a first mesh group 23 and a second mesh group 24 are provided on the oil filter plate. The first mesh group 23 is located above the first oil net 11, and the second mesh group 24 is located above the second oil net 12. This allows the oil smoke, after passing through the first and second oil nets 11 and 12, to be filtered again by the first and second mesh groups 23 and 24, thereby achieving a double filtration effect on the oil smoke. Furthermore, by providing a first noise reduction member 421 and a second noise reduction member 422, the oil smoke, after passing through the first mesh group 23, enters the noise reduction groove 40 of the first noise reduction member 421. Similarly, the oil smoke, after passing through the second mesh group 24, enters the noise reduction groove 40 of the second noise reduction member 422. This not only reduces noise, but also provides a third level of filtration for the oil smoke, further enhancing the oil filtration effect.

[0038] Optionally, the depth of the noise reduction groove 40 is 12-15 mm to ensure the noise reduction effect. Specifically, in this embodiment, the depth of the noise reduction groove 40 is 12 mm.

[0039] Optionally, the apertures of the first mesh group 23 and the second mesh group 24 are 0.8-2 mm, primarily for noise reduction. When the first mesh group 23 is covered by the first noise reduction member 421, more oil smoke can flow along the first filter plate 201 where the first mesh group 23 is located, thereby achieving condensation. Similarly, when the second mesh group 24 is covered by the second noise reduction member 422, more oil smoke can flow along the second filter plate 202 where the second mesh group 24 is located, thereby achieving condensation. Specifically, in this embodiment, the apertures of the first mesh group 23 and the second mesh group 24 are 0.8 mm.

[0040] Optionally, the first oil net 11 includes a first mesh 111 and a second mesh 112, the first mesh 111 is tilted upward from the side close to the second oil net 12 to the side away from the second oil net 12, the second mesh 112 is connected to the side of the first mesh 111 away from the second oil net 12, and the second mesh 112 is tilted downward from the side close to the second oil net 12 to the side away from the second oil net 12, the first mesh 111 is arranged parallel to the first filter plate 201, so as to facilitate the setting of the first filter plate 201, which is beneficial to reducing the space occupied by the first filter plate 201, and further beneficial to the miniaturization of the range hood. The second oil net 12 includes a third mesh 121 and a fourth mesh 122. The third mesh 121 is tilted upward from the side close to the first oil net 11 to the side away from the first oil net 11. The fourth mesh 122 is connected to the side of the third mesh 121 away from the first oil net 11, and the fourth mesh 122 is tilted downward from the side close to the first oil net 11 to the side away from the first oil net 11. The third mesh 121 is arranged parallel to the second filter plate 202 to facilitate the arrangement of the second filter plate 202, which is beneficial to reducing the space occupied by the second filter plate 202, and further beneficial to the miniaturization of the range hood.

[0041] Optionally, a third mesh group 25 and a fourth mesh group 26 are further included. The third mesh group 25 is provided on the first filter plate 201 and is located above the second mesh sheet 112. The fourth mesh group 26 is provided on the second filter plate 202 and is located above the fourth mesh sheet 122. By providing the third mesh group 25 and the fourth mesh group 26, more oil smoke can be double-filtered, further improving the oil smoke filtration effect.

[0042] Optionally, it also includes a first driving structure 411 and a second driving structure 412. The first driving structure 411 is connected to the first noise reduction member 421 for driving the first noise reduction member 421 to move relative to the first filter plate 201 to switch between the two states of covering the first mesh group 23 and opening the first mesh group 23. The second driving structure 412 is connected to the second noise reduction member 422 for driving the second noise reduction member 422 to move relative to the second filter plate 202 to switch between the two states of covering the second mesh group 24 and opening the second mesh group 24.

[0043] Specifically, when the stove located below the first oil net 11 is turned on alone, the first transmission structure operates and drives the first noise reduction component 421 to move and open the first mesh group 23, and the second transmission structure drives the second noise reduction component 422 to move and cover the second mesh group 24, thereby transferring the negative pressure center of the range hood to a position close to the first oil net 11, which is beneficial to reducing the amount of oil smoke escaping. At the same time, since the first noise reduction component 421 located at the first mesh group 23 is in an open state, the flow of oil smoke is smoother, further reducing the noise generated by the flow of smoke. Similarly, when the range hood located below the second oil screen 12 is turned on alone, the second transmission structure operates to drive the second noise reduction member 422 to move and open the second mesh group 24, while the first transmission structure drives the first noise reduction member 421 to move and cover the first mesh group 23. This shifts the negative pressure centerline of the range hood to a position closer to the second oil screen 12, thereby reducing the amount of oil smoke escaping. At the same time, since the second noise reduction member 422 located at the second mesh group 24 is in the open state, the flow of oil smoke is smoother, further reducing the noise generated by the flow of smoke. When both the range hoods located below the first oil screen 11 and the second oil screen 12 are turned on, the first transmission structure operates to drive the first noise reduction member 421 to move and open the first mesh group 23, while the second transmission structure operates to drive the second noise reduction member 422 to move and open the second mesh group 24, facilitating the smooth flow of oil smoke and reducing the noise generated by the flow of smoke.

[0044] Optionally, one side of the first noise reduction member 421 is hinged to the first filter plate 201, and the first transmission structure can drive the first noise reduction member 421 to swing relative to the first filter plate 201 to cover or open the first mesh group 23. One side of the second noise reduction member 422 is hinged to the second filter plate 202, and the second transmission structure can drive the second noise reduction member 422 to swing relative to the second filter plate 202 to cover or open the second mesh group 24.

[0045] Optionally, a third air inlet is further provided on the lower side of the fume hood 3, located between the first and second air inlets. A third oil screen 13 is provided at the third air inlet. The oil filter plate further includes a third filter plate 200, which is located between the first and second filter plates 201, 202. The third filter plate 200 is provided with a fifth mesh group 21 and a sixth mesh group 22, which are spaced apart. A condensation plate is provided between the fifth and sixth mesh groups 21, 22, and is located above the third oil screen 13. By providing the third air inlet and arranging the third oil screen 13 at the third air inlet, the air inlet area is increased while ensuring the filtration effect of oil fumes. By arranging a condensation plate above the third oil net 13, the oil smoke filtered by the third oil net 13 can be further condensed on the condensation plate, thereby improving the filtering effect of the oil smoke, and by arranging a fifth mesh group 21 on one side of the condensation plate and a sixth mesh group 22 on the other side of the condensation plate, the oil smoke flowing along the condensation plate can be filtered again by the fifth mesh group 21 or the sixth mesh group 22 and then discharged, thereby further improving the filtering effect of the oil smoke, and then, the oil smoke entering the range hood through the third air inlet is triple filtered, so that the range hood has a better oil filtering effect.

[0046] Optionally, the hinge between the first noise reduction member 421 and the oil filter plate is located between the first mesh group 23 and the fifth mesh group 21, and the hinge between the second noise reduction member 422 and the oil filter plate is located between the second mesh group 24 and the sixth mesh group 22. When the first noise reduction member 421 is in the state of opening the first mesh group 23 and the second noise reduction member 422 is in the state of opening the second mesh group 24, the first noise reduction member 421 is tilted from bottom to top toward the direction close to the second noise reduction member 422, and the second noise reduction member 422 is tilted from bottom to top toward the direction close to the first noise reduction member 421. In addition, the first noise reduction member 421 and the second noise reduction member 422 are spaced apart so that the oil smoke discharged through the fifth mesh group 21 and / or the sixth mesh group 22 can be guided by the tilted first noise reduction member 421 and the second noise reduction member 422, thereby accelerating the flow speed of the oil smoke and thereby improving the oil smoke suction effect of the range hood.

[0047] Optionally, the third oil net 13 is arranged in parallel with the third filter plate 200 so that the third filter plate 200 can be arranged close to the third oil net 13, avoiding the third filter plate 200 occupying too much space, which is conducive to the miniaturization of the range hood.

[0048] Please refer to Figure 6 and Figure 7Optionally, it also includes an oil cup 6, which is arranged on the lower side of the rear end of the smoke hood 3. The oil filter structure 2, the first oil net 11, the second oil net 12 and the third oil net 13 are all arranged to be tilted downward from front to back, and the rear end of the oil filter structure 2, the rear end of the first oil net 11, the rear end of the second oil net 12 and the rear end of the third oil net 13 all extend into the oil cup 6 or are located on the upper side of the oil cup 6, so that the oil stains on the oil filter structure 2, the first oil net 11, the second oil net 12 and the third oil net 13 can flow smoothly into the oil cup 6.

[0049] Optionally, the oil filter structure 2, the first oil net 11, the second oil net 12 and the third oil net 13 form an angle a with the horizontal plane from front to back, and the value range of the angle a is 3-8°. In this embodiment, the angle a is 3°.
