[0030] As shown in Figure 1 , the utility model embodiment provides an oil screen, including the body 1 of board shape, the body 1 is equipped with multiple air inlets 10 that pass through the body, for oil fume to pass through. In order to describe clearly, define Figure 1 In the upper, lower, define the direction of oil fume exhauster towards user as front, away from user as back, in the use process, the air inlet direction is from the body 1 lower to the body 1 upper, namely the body 1 lower is the air inlet side, the upper is the air outlet side. The both ends of the body 1 extend towards the air inlet side and are provided with the flow guide plate 2. As shown in Figure 2 、 Figure 3 , the utility model embodiment provides an oil screen, which is arranged inside the shell 3 of the oil fume exhauster during installation and use, the flow guide plate 2 divides the inside of the shell 3 of the oil fume exhauster into an oil inlet area 31 and two smoke-free areas 32, the oil inlet area 31 is in communication with the oil inlet port 33 of the shell 3 of the oil fume exhauster, and the smoke-free areas 32 are located on both sides of the oil inlet area 31. The oil fume enters the inside of the shell 3 of the oil fume exhauster from the oil inlet port 33 of the shell 3, and then enters the oil inlet area 31 between the two flow guide plates 2. The oil fume is limited by the two flow guide plates 2 and cannot flow to the smoke-free areas 32 on both sides, but can only pass through the air inlet port 10 upwards and flow into the cabinet 4 above the oil fume exhauster. The flow guide plate 2 has both a flow guiding effect and a partitioning effect, so that the parts arranged in the smoke-free areas 32 on both sides are free from oil pollution.
[0031] When the oil fume exhauster is running, oil stains will be left on the body 1. When the cabinet 4 above is cleaned, sewage will also accumulate on the body 1. In order to guide the oil stains and sewage on the body 1, so that they can be collected and discharged from the flow guide plate 2, in an embodiment of the utility model, as shown in Figure 1 、 Figure 4 、 Figure 5 , the width of the flow guide plate 2 gradually increases along the air inlet direction. In addition, the edge of the flow guide plate 2 extends outward and is provided with a flow guide folding edge 21. In this embodiment, the flow guide folding edge 21 is arranged on both sides and the bottom of the flow guide plate 2, and the top is in communication with the top of the body, so that the oil stains and sewage on the top of the body can be collected to the bottom end of the flow guide plate 2 along the flow guide folding edge 21, and then flow into the oil cup below. The flow direction is shown by the arrow direction in Figure 5 .
[0032] In order to prevent the oil stains and sewage on the body 1 from flowing to the outside of the oil screen and dripping onto the cooking bench, in an embodiment of the utility model, as shown in Figure 1 、 Figure 4As shown, both sides (front side and rear side) of the body 1 are upwardly extended with a first baffle 11, and the edge of the air inlet 10 is extended with a second baffle 12 toward the air outlet side. The flow channel for oil dirt and sewage is formed between the first baffle 11 and the second baffle 12, and finally converges at the guide plate 2 on both sides and flows into the oil cup below.
[0033] When the range hood is cleaning the upper box 4, the sewage discharge position is located at the top front side of the body 1, and when the sewage is discharged, the sewage may splash and drip onto the stove below through the air inlet 10. In order to solve the above problem, as shown in Figure 1 、 Figure 4 In an embodiment of the utility model, the body 1 is provided with an air inlet portion 13 protruding toward the air outlet side, the air inlet 10 is arranged on the air inlet portion 13, and the front side of the air inlet portion 13 is provided with a third baffle 131. The third baffle 131 can block the splashing sewage to prevent it from dripping onto the stove below through the air inlet 10. Preferably, the height of the third baffle 131 is greater than 12 mm. Further preferably, the height of the third baffle 131 is 15 mm, which can block the splashing of the sewage.
[0034] In order to collect the oil dirt condensed on the bottom surface of the body 1, as shown in Figure 1 、 Figure 4 In an embodiment of the utility model, the height of the body 1 gradually decreases from front to back. The oil dirt on the bottom surface of the body 1 flows from front to back along the bottom surface of the body 1 under the action of gravity and finally falls into the oil cup below the rear end of the body 1. Preferably, the included angle between the body 1 and the horizontal plane is greater than 6°. Further preferably, the included angle between the body 1 and the horizontal plane is 15°.
[0035] As shown in Figure 6 In order to facilitate cleaning the air inlet 10 of the oil screen, a rectangular notch is arranged in the body 1, a plurality of detachable flow uniforming ribs 14 are arranged in the notch (for example, the flow uniforming ribs 14 are arranged in the grooves on the edges of the notch), and the air inlet 10 is formed between two adjacent flow uniforming ribs 14. When the oil screen needs to be cleaned, the flow uniforming ribs 14 can be removed, and then the body 1 and the flow uniforming ribs 14 can be cleaned respectively, which improves the convenience of cleaning. In addition, the size of the air inlet 10 can be adjusted as needed, and only the distance between adjacent flow uniforming ribs 14 needs to be adjusted.
[0036] As shown in Figures 2-6As shown, the utility model also provides a kind of range hood, including shell 3 and above oil screen.The shell 3 front side is equipped with smoke inlet 33, and the shell 3 top is equipped with smoke outlet 34.The oil screen is located in the shell 3 inside, and the oil screen body 1 covers the smoke outlet 34 from below.The range hood provided in the utility model embodiment, oil screen is located in the inside of range hood shell 3, can solve the problem that oil stain of smoke inlet 33 inconveniently set oil screen range hood (for example, flap range hood) drops to cooking bench, and the middle part of shell 3 is equipped with oil screen, can also guarantee product safety.In addition, the oil screen is not set in smoke inlet 33, and the oil screen in the inside of shell is cleaned conveniently.Further, the baffle 2 of the oil screen divides the shell 3 inside into one smoke zone 31 and two smokeless zones 32, the smoke zone 31 is communicated with the smoke inlet 33, and the smokeless zone 32 is located in the two sides of the smoke zone 31.The components of range hood are located in two smokeless zones 32, and the components of range hood can be avoided by oil fume erosion.
[0037] The shell 3 top is equipped with box body 4, and is connected with the smoke outlet 34 of the shell 3, and the box body 4 is equipped with fan 41 in, and this is prior art, and no longer elaborate.The oil screen is located in the bottom of the smoke outlet 34, and the oil stain dropped from box body 4 is intercepted, to prevent it from falling on the cooking bench below.The width of the body 1 left-right direction is greater than the width of the smoke inlet 33, and the front-back direction covers the whole area of the smoke inlet 33.Oil drops into the body 1 on the inner wall of box body 4, and finally is collected into oil cup through the baffle 2 of two sides, and the oil at the bottom of the body 1 is guided into oil cup along the surface thereof from front to back.
[0038] The above only for the preferred embodiment of the utility model, and not for limiting the utility model, for the person skilled in the art, the utility model can have various changes and changes.Any modification, equivalent replacement, improvement etc.that is made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
