The embodiment provides an air deflector and a range hood comprising the same. As shown in fig. 1 to fig. 3, the range hood further includes a smoke collection cover 2, and the air deflector 1 is movably connected to the smoke collection cover 2. The air deflector 1 is flat, an oil guide member 11 is arranged on the back surface of the air deflector 1, and the oil guide member 11 protrudes out of the back surface of the air deflector 1. The fume collecting hood 2 is provided with an oil collecting groove 21, and the lowest end of the oil guide piece 11 is positioned above the oil collecting groove 21.

From the side of aviation baffle 1 to the direction of the middle part of aviation baffle 1, oil guide 11 reduces gradually, and the greasy dirt that condenses at the aviation baffle 1 back can assemble together along oil guide 11 upper surface, just has clean processing, has solved the problem that the greasy dirt that condenses on the plane can flow scattered all around.

In the cooking process, the oil smoke rising upwards has certain impulsive force, so that the air deflector 1 is not worried about that oil stains gathered through the oil guide piece 11 can drip down when being opened. After cooking, the air deflector 1 is closed, the impact force of the rising oil smoke is lacked, and oil stains condensed at the tail end of the oil guide piece 11 flow downwards until entering the oil collecting groove 21, so that subsequent uniform collection and cleaning are facilitated.

The specific shape of the oil guide member 11 is not limited, and the oil guide member can collect and collect the scattered oil stains. Preferably, the oil guide 11 has a V shape, and the lowest end of the oil guide 11 forms an oil discharge port. Namely, the oil stains on the left side and the right side of the back of the air deflector 1 are gathered to the oil discharge port in the middle by the two inclined-line-shaped flow guide structures, so that the problem that the oil stains are too dispersed to be cleaned is avoided.

On the basis of the structure, the back surface of the air deflector 1 is also provided with an oil guide nozzle 12, and the oil guide nozzle 12 is positioned at the oil discharge port and extends towards the direction far away from the air deflector 1. When the air deflector 1 is closed, the end of the oil guide nozzle 12 is positioned above the oil collecting groove 21.

The oil guiding nozzle 12 is preferably a sheet structure arranged obliquely downwards, and oil dirt gathered at the oil discharge port can flow downwards along the oil guiding nozzle 12 and far away from the air deflector 1. The oil dirt flows to the end of the oil guide nozzle 12 and then is separated from the oil guide nozzle 12 and falls into the oil collecting groove 21.

As shown in fig. 4 to 6, the range hood further includes an oil baffle plate 3, the fume collecting hood 2 is provided with an air inlet 22, a lower edge 23 of the air inlet 22 is provided with a plurality of oil leakage holes 24, and an oil collecting groove 21 is formed between the lower edge 23 and the oil baffle plate 3. That is, the oil leakage hole 24 is formed in the side surface of the oil sump 21, and oil stains condensed on the wall surface around the air inlet 22 flow down to the lower edge 23 and then flow into the oil leakage hole 24. Similarly, after the oil stain separated from the end of the oil guide nozzle 12 falls into the oil collecting tank 21, the oil stain also enters the exhaust fume collecting hood 2 through the oil leakage hole 24, and finally enters the oil cup of the range hood.

Because the areas of the oil baffle plate 3 and the smoke collecting hood 2 are both large, the flatness is difficult to achieve. As long as the roughness of oil baffle 3 and collection petticoat pipe 2 has the flaw slightly, no matter connect through pasting or welded mode, all can have the gap between oil baffle 3 and the collection petticoat pipe 2, and the greasy dirt that gets into oil trap 21 probably passes and oozes from the lower border of oil baffle 3 behind this gap, has reduced range hood's greasy dirt collection ability, has increased the clearance degree of difficulty on range hood surface.

To solve this problem, a blocking rib 25 extending in the lateral direction (substantially horizontal direction) is provided between the oil baffle plate 3 and the smoke collecting hood 2, and the oil leakage hole 24 is located above the blocking rib 25. The blocking edge 25 can be designed to be narrower, so that the difficulty of flatness processing is reduced, and the blocking edge 25 can be processed to be smoother even if being longer. When the oil baffle plate 3 is connected to the fume collecting hood 2, the design of the blocking rib 25 can ensure that no gap exists between the oil baffle plate 3 and the fume collecting hood 2, and oil dirt falling into the oil collecting groove 21 can enter the fume collecting hood 2 through the oil leakage hole 24 and cannot seep out from the bottom of the oil baffle plate 3.

The specific processing mode of the blocking rib 25 is not limited, and no gap can be formed between the oil baffle plate 3 and the fume collecting hood 2. In a preferred embodiment, the exhaust hood 2 is stamped with blocking ribs 25 in the direction of the oil baffle 3. After installation, the blocking edge 25 abuts against the oil baffle plate 3, and the blocking edge 25 and the oil baffle plate 3 are tightly attached.

The length, width, height and other data of the blocking rib 25 are not particularly limited, and may be determined according to specific use requirements, as long as the oil stains falling into the oil collecting tank 21 are blocked by the blocking rib 25 and all flow into the oil leakage hole 24.

The smaller the distance L between the bottom edge of the oil leakage hole 24 and the upper surface of the blocking rib 25, the better, the more easily the oil stain blocked by the blocking rib 25 enters the oil leakage hole 24. The smaller the distance L1 between the end face of the blocking edge 25 and the inner surface of the oil baffle plate 3 is, the better the oil stain seepage can be effectively blocked.

On the basis of the structure, the oil baffle plate 3 is bonded or welded on the blocking edge 25, and the connecting structure of the oil baffle plate 3 and the fume collecting hood 2 is more stable. Preferably, the oil baffle plate is connected in a bonding mode, the liquid adhesive has fluidity and can completely fill a gap between the end surface of the side of the blocking edge 25 and the inner surface of the oil baffle plate 3, and after the adhesive is cured, the end surface of the side of the blocking edge 25 and the inner surface of the oil baffle plate 3 are completely sealed, so that the oil dirt in the oil collecting tank 21 can only enter the oil leakage hole 24 and cannot seep out from the bottom of the oil baffle plate 3.

Fig. 7 and 8 show another preferred forming mode of the blocking rib 25, the jointed oil baffle plate 3 and the smoke collecting hood 2 are punched and formed towards the smoke collecting hood 2 synchronously, an outer blocking groove 31 is formed on the oil baffle plate 3, an inner blocking groove 26 is formed on the smoke collecting hood 2, and the oil leakage hole 24 is positioned above the inner blocking groove 26. The inner blocking groove 26 and the outer blocking groove 31 which are buckled with each other jointly form a blocking edge 25, so that the effect of blocking oil stains from seeping out from the space between the smoke collecting hood 2 and the oil baffle plate 3 is realized.

The outer blocking groove 31 abuts against the inner blocking groove 26, the outer blocking groove and the inner blocking groove are attached tightly, and the oil stain blocking effect is better. The mode that keeps off the synchronous stamping forming of oil board 3 and collection petticoat pipe 2 can install oil board 3 at collection petticoat pipe 2, and in order to further improve the stability of connecting, the outside blocks recess 31 and inboard blocks cohering or welding between the recess 26, utilizes the gap of adhesive or solder filling between oil board 3 and the collection petticoat pipe 2, and the leakproofness is better.
