As shown in fig. 1 to 6, the present embodiment provides a range hood including a smoke collecting chamber 120, a bellows 110, a baffle 200, a scroll 300, and a main oil guide plate 410. The smoke collecting cavity 120 is provided with a top suction part which is arranged in a transversely extending way and a side suction part which is arranged in a longitudinally extending way, the lower end surface of the top suction part is provided with a top smoke suction port, and the side suction part is connected with the rear end of the top suction part; the bellows 110 is located above the smoke collecting chamber 120 and connected to the top suction part of the smoke collecting chamber 120; the volute 300 is arranged in the bellows 110; the baffle 200 is arranged in the top suction part of the smoke collecting cavity 120, the baffle 200 comprises an oil baffle part 210 which is arranged in a transverse extending mode and an oil guide part 220 which is arranged in a longitudinal extending mode, the oil baffle part 210 is positioned above the top smoke suction port and below the volute 300, the oil guide part 220 is connected to the rear end of the oil baffle part 210 and is provided with a smoke through hole 221, and smoke can enter the volute 300 through the top smoke suction port and the smoke through hole 221 in sequence; the leading oil plate 410 is disposed at the lower end of the scroll case 300, and the trailing end thereof extends out of the trailing end of the oil baffle 210, and the leading oil plate 410 is used for guiding the oil of the scroll case 300.

Through setting up baffle 200 between spiral case 300 and top smoking mouth, baffle 200's fender oil portion 210 can bear the oil of dripping on the spiral case 300, avoids effectively that the oil on the spiral case 300 from the middle part whereabouts of lampblack absorber, prevents that oil from the top smoking mouth whereabouts to the operation panel to influence user's use experience. By providing the oil guide 220 having the smoke passing hole 221 below the rear end of the oil baffle 210, the smoking effect is also ensured. Correspondingly, the lower extreme of spiral case 300 is provided with leading oil board 410, and the fluid of spiral case 300 mostly can be guided to the rear of bellows 110 by leading oil board 410, still can not cause the pollution to the lampblack absorber inside when being convenient for collect, has improved user's use experience and has felt.

It should be noted that, the end close to the user is the front end, and the end far away from the user is the rear end.

In this embodiment, the front end and two sides of the oil baffle portion 210 are connected with the inner wall of the bellows 110 in a sealing manner, so as to avoid the oil on the oil baffle portion 210 from dripping or exuding from the connection between the oil baffle portion 210 and the bellows 110. Optionally, the front and two sides of the oil blocking portion 210 are both provided with a connection flange 212, and the connection flange 212 can block oil on one hand, and also facilitate connection between the baffle 200 and the bellows 110 on the other hand.

As an alternative to a range hood, the front end of the main oil guide plate 410 is connected to the lower end of the scroll case 300, and the middle of the main oil guide plate 410 is connected to the oil blocking part 210. That is, the scroll case 300 is connected to the oil baffle 210 through the main oil guide plate 410, so that the scroll case 300 is more conveniently fixed through the main oil guide plate 410 and the disassembly is more convenient than the mode of fixing the scroll case 300 on the inner wall of the bellows 110 in the prior art.

Optionally, to facilitate the installation of the main oil guide 410 with the scroll 300, a front end of the main oil guide 410 is provided with a mounting flange 411, and is connected with the scroll 300 through the mounting flange 411. In order to facilitate the installation of the main oil guide plate 410 and the oil baffle portion 210, a through hole is provided in the middle of the main oil guide plate 410, an installation hole is provided in the oil baffle portion 210, and an installation bolt passes through the through hole and is screwed with the installation hole.

Further, the oil guiding flanges 412 are disposed on two sides of the main oil guide plate 410, so that oil can be effectively prevented from dripping from two sides of the main oil guide plate 410. Meanwhile, the distance between the two oil guiding flanges 412 at the end far away from the volute 300 is smaller than the distance between the two oil guiding flanges 412 at the end close to the volute 300, and the distance between the two oil guiding flanges 412 at the rear end of the main oil guide plate 410 is reduced to further collect oil, so that the subsequent collection of oil is facilitated.

In this embodiment, the oil blocking portion 210 is provided with a profiling, and the rear ends of the left and right sides of the oil blocking portion 210 are provided with protrusions 211, so that the strength of the oil blocking portion 210 can be enhanced by providing the profiling and the protrusions 211.

Further, the bottom of the oil collecting groove 222 is provided with an oil drain hole 223 corresponding to the auxiliary oil guide plate 420, the auxiliary oil guide plate 420 is connected to the oil guide part 220 and located below the oil drain hole 223, and the oil in the oil collecting groove 222 can further enter the auxiliary oil guide plate 420 through the oil drain hole 223. By arranging the auxiliary oil guide plate 420, the oil flowing into the oil collecting grooves 222 of the oil baffle part 210 is further guided, so that the oil is prevented from polluting the inside of the range hood. The auxiliary oil guide plate 420 is located below the oil leakage hole 223, so that oil passing through the oil leakage hole 223 can naturally drip on the auxiliary oil guide plate 420 by means of gravity, and the oil can be collected more reliably.

Preferably, the smoke vent 221 is circumferentially provided with an oil blocking flange extending toward the rear end of the oil guide 220. Through setting up the oil blocking flanging at the circumference of leading to the smoke vent 221 for the fluid that keeps off oil portion 210 drip can not pass through the smoke vent 221, avoids the influence of flue gas to fluid on the one hand, on the other hand can also play the guide effect to the collection of fluid, makes the fluid can get into oil collection recess 222 smoothly.

In one embodiment, as shown in fig. 3 and 4, the range hood is further provided with a smoke guide plate 500, the smoke guide plate 500 is disposed at a side suction portion of the smoke collecting chamber 120, and an upper end of the smoke guide plate 500 is inclined toward the rear. Meanwhile, a side smoking port opposite to the smoke guide plate 500 is opened at the front side of the side smoking part. By providing the smoke guide plate 500 on the smoke collecting chamber 120, the smoke passing through the side smoke outlet can be further guided by the smoke guide plate 500, so that the smoke can smoothly enter the scroll 300. Optionally, a tobacco inlet mesh 121 is also provided at the top smoking mouth.

It should be noted that, in order to avoid polluting the smoke guide 500 when the oil of the main oil guide 410 drops, the upper end of the smoke guide 500 is provided with the oil drop hole 510, the oil drop hole 510 is located below the rear end of the main oil guide 410, and the oil dropped from the main oil guide 410 can directly pass through the oil drop hole 510. Similarly, in order to prevent the oil of the auxiliary oil guide plate 420 from polluting the smoke guide plate 500 when dropping, a plurality of oil dropping holes 510 are formed in the upper end of the smoke guide plate 500, and besides the oil dropping holes 510 facing the lower part of the rear end of the main oil guide plate 410, the oil dropping holes 510 are also formed facing the lower part of the rear end of the auxiliary oil guide plate 420. Specifically, a flange is provided on the smoke guide plate 500 in the rear direction, and the oil drop hole 510 is provided on the flange.

Preferably, the range hood further comprises an oil box 600 disposed below the oil dropping hole 510, wherein the oil box 600 is used for accommodating the oil dropped from the main oil guide plate 410 and the auxiliary oil guide plate 420, so as to facilitate the collection and treatment of the oil.
