[0027] like Figure 1-3 As shown, a range hood includes a housing 1 and a smoke collection hood 2 disposed below the housing 1. The smoke collection hood 2 has a smoke collection chamber 3 inside, and an air outlet 211 communicating with the housing 1 is provided on the top of the smoke collection hood 2. The smoke collection hood 2 has a main air inlet 4 opposite to the air outlet 211. Auxiliary air inlets 5 are respectively provided on both sides of the main air inlet 4. A guide plate 7 is provided between the main air inlet 4 and the two auxiliary air inlets 5. The two guide plates 7 divide the smoke collection chamber 3 into a main air inlet channel 31 and two auxiliary air inlets. The main air intake channel 31 is formed between the two guide plates 7 and the side wall of the corresponding smoke hood 2. The top of the guide plate 7 and the smoke hood 2 are provided with a duct gap 33 for air supply. The air entering from the main air inlet 4 enters the housing 1 through the main air intake channel 31 and the air outlet 211. The air entering from the auxiliary air inlet 5 enters the housing 1 through the auxiliary air intake channel 32, the duct gap 33, the main air intake channel 31 and the air outlet 211.

[0028] In this embodiment, the main air intake channel 31 and the auxiliary air intake channel 32 are separated by the guide plate 7 and a duct gap 33 is provided, so that the main air intake channel 31 and the auxiliary air intake channel 32 are relatively independent. The air intake of the auxiliary air intake channel 32 is more concentrated, which makes the negative pressure distribution concentrated, increases the flow rate of the suction air, and improves the smoke extraction effect of the range hood.

[0029] In one embodiment, an oil mesh 6 is provided in the smoke collection chamber 3 opposite to the air outlet 211. The oil mesh 6 extends downward on both sides to form guide plates 7. The two guide plates 7 are respectively connected between the main air inlet 4 and the adjacent auxiliary air inlet 5.

[0030] like Figure 1-3As shown, the smoke hood 2 is formed by a top plate 21, a rear plate 22, a bottom plate 23, a front plate 24, and side plates 25 on the left and right sides connected in sequence, forming a smoke collection chamber 3 inside; the air outlet 211 is set on the top plate 21 and communicates with the smoke collection chamber 3. The top plate 21 and the bottom plate 23 are both set horizontally, the rear plate 22 is set vertically, the front plate 24 is set from top to bottom and tilted backward, the main air inlet 4 and the auxiliary air inlet 5 are set on the front plate 24 and communicate with the smoke collection chamber 3 respectively, and the guide plate 7 is connected to the front plate 24.

[0031] The front panel 24 is tilted downwards and backwards to facilitate the main air inlet 4 and the auxiliary air inlet 5 in drawing smoke from the stove.

[0032] like Figure 4 , 5 As shown, the oil mesh 6 includes a frame 61, on which mesh holes 62 are distributed. The edges of the mesh holes 62 are folded inward to form a first flange 63. A first oil guiding channel 64 is formed between the first flanges 63 of two adjacent mesh holes 62, and the first oil guiding channel 64 extends from top to bottom.

[0033] like Figure 4 As shown, in another embodiment, the edges of the main air inlet 4 and the auxiliary air inlet 5 are folded inward to form a second flange 242, and a second oil guide channel 243 is formed between the second flange 242 of the main air inlet 4 and the adjacent auxiliary air inlet 5, and the guide plate 7 is connected to the interior of the second oil guide channel 243.

[0034] By setting up the first oil guiding channel 64 and the second oil guiding channel 243, when the oil fumes pass through the oil mesh 6, the main air inlet 4 and the auxiliary air inlet 5, the oil can be discharged into the oil guiding groove of the fume hood 2 along the first oil guiding channel 64 and the second oil guiding channel 243.

[0035] To facilitate the adsorption of oil by the oil mesh 6 and the collection of oil after adsorption by the smoke hood 2, the angle between the plane of the oil mesh 6 and the front plate 24 is between 5° and 35°.

[0036] like Figure 4 , 5 As shown, the deflector 7 is formed by the upper side 71, the rear side 72, the lower side 73 and the front side 74 connected in sequence. The upper side 71 is fixedly connected to the side frame of the frame 61, the rear side 72 abuts against the rear plate 22, the lower side 73 is connected to the bottom plate 23, and the front side 74 abuts against the front plate 24.

[0037] The rear side 72, lower side 73, and front side 74 of the baffle 7 are respectively attached to the corresponding inner walls of the smoke hood 2. Only the top plate 21 of the smoke hood 2 and the upper side 71 of the baffle 7 are left to allow air to enter the main air intake channel 31 through the air duct gap 33 from the auxiliary air intake channel 32. This structure makes the air intake of the auxiliary air intake channel 32 more concentrated and the negative pressure distribution more concentrated, thus improving the smoke extraction effect of the range hood.

[0038] In this embodiment, the guide plate 7 and the oil mesh 6 are integrally formed, which can reduce production costs and make installation and cleaning easier.

[0039] like Figure 6 As shown, in one embodiment, the front panel 24 is provided with an inwardly recessed cavity 241, and an electrical mounting plate 8 is provided inside the cavity 241. A control module is connected to the electrical mounting plate 8, and the top of the electrical mounting plate 8 is hinged to the front panel 24.

[0040] An electrical mounting plate 8 is provided on the front side of the front panel 24 of the fume hood 2 to facilitate electrical control of the fume hood 2. By hinged the top of the electrical mounting plate 8 to the front panel 24, the electrical mounting plate 8 can be flipped upward when using the fume hood 2, exposing the main air inlet 4 and the auxiliary air inlet 5 on the front panel 24 above the stove, which facilitates the fume extraction of the fume hood 2.

[0041] In another embodiment, the front side of the electrical mounting plate 8 is provided with a panel 9 fixed thereto. The size of the panel 9 is adapted to the front plate 24, and the panel 9 is provided with control buttons that are electrically connected to the control module.

[0042] The front panel 9 of the electrical mounting plate 8 is connected to improve the aesthetics of the smoke hood 2.
