Embodiment 1

[0031] see Figure 1 ~ Figure 4 , a range hood. In this embodiment, it is a near-suction range hood, including a smoke collection hood 1, a fan cover 2 and a fan 3. The smoke collection hood 1 is installed under the fan cover 2, and the fan 3 is installed under the fan cover. 2 and partially located on the back side of the fume hood 1.

[0032] The front of the fume collecting hood 1 is provided with panels, including an upper panel 41 and a lower panel 42 , an oil screen 5 is arranged between the upper panel 41 and the lower panel 42 , and the side of the fan 3 facing the oil screen 5 has an air inlet 31 . A rotatable smoke baffle 6 is arranged above the oil screen 5 . When the range hood is turned on, the smoke baffle 6 is turned upwards to expose the oil net 5 , and when the range hood is turned off, the smoke baffle 6 is turned downwards to cover the oil net 5 .

[0033] The oil screen 5 includes a frame 51 and a plurality of blades arranged in the frame 51 , the frame 5...

Embodiment 2

[0051] see Figure 5 and Figure 6 , in this embodiment, the difference from the first embodiment above is that the air intake angles of the first vane 521 and the second vane 522 (the angle between the two planes formed by obliquely setting relative to the frame 51) are the same, both is α, the width of each blade is L, the distance between the first blades 521 is d, and the u between the second blades 522 is di, the above parameters satisfy the following relationship: d

[0052] d>L, this is to ensure one-time processing through the mold and save costs;

[0053] L>d*cosα, this is to ensure that adjacent first blades 521 and second blades 522 project overlapping parts along the direction of the vertical blades, thereby ensuring the guiding effect of the first blades 521 and the second blades 522;

Abstract

The invention discloses an oil screen used for a range hood. The oil screen comprises a frame and multiple blades arranged in the frame. Each blade is arranged in the width direction of the frame. All the blades are arranged in parallel in the length direction of the frame to form a grating shape. The oil screen is characterized in that the blades include at least two first blades located in the middle and at least two second blades located on the two sides of the first blades; and the air inlet area, at the positions of the second blades, of the oil screen is larger than the air inlet area, at the positions of the first blades, of the oil screen. The invention further discloses the range hood applying the oil screen. The blades of the type are arranged, the angle of the blades on the two sides is large, the angle of the blades in the middle is small, the interval of the blades on the two sides is large, the interval of the blades in the middle is small, and therefore the negative pressure moves towards the two sides, and the lampblack suction effect is improved.

Description

technical field [0001] The invention relates to a range hood, in particular to an oil net used for the range hood, and a range hood with the oil net applied thereto. Background technique [0002] Along with the improvement of living standard, the raising of the requirement of quality of life, range hood is used widely in each family as the important electric appliance that sucks the lampblack that produces when cooking in the family kitchen. The main problem at present is that when the range hood is working, the oil fume passing through the air duct tends to accumulate a large amount of oil in the air duct. Due to the high viscosity of the formed oil, it is difficult to discharge from the air outlet of the air duct, causing oil pollution to the pipeline. The corrosion of the range hood reduces the service life of the range hood and increases the use and maintenance costs of the range hood, while the other part is directly discharged. The range hood contains a large number of...
