Problems solved by technology

If it is used on a top-suction range hood, it is inconvenient because the volume cannot be reduced, and it also affects the appearance
Now there are many oil screens used on top suction range hoods, some of which only function as a protective fence and hardly have a filtering effect on oil fume, and some filter oil fume better, but they are not easy to clean and easy to block
The technical solution of these oil screens is to increase the density of the oil screen to improve the separation degree of oil, but it will lead to disadvantages such as poor air intake, easy blockage, and difficult cleaning during use.

Embodiment 1

[0024] Embodiment 1, as shown in FIG. 1 : the left side of the mesh bar 1 is turned up, and the right side is turned up, so that two adjacent mesh bars form a side air inlet 5 . The oil fume passes through the mesh bar 1 upwards and sticks to the mesh bar to the upper right. According to the principle of fluid mechanics, the oil fume guides the mesh bar to roll upward, the oil fume contacts, collides, adheres to the mesh bar 1, and is finally exported. The filtered oil fume enters the fan upward and is discharged by the fan. Because it is side air intake, the air inlet 5 seen in the front is very small or just does not have, and there will be no oil dripping and oil leakage phenomenon to take place.

Embodiment 2

[0025] Embodiment two, as shown in Figure 2-a: divide the single-layer oil screen described in the implementation side one into front and back two layers, there is a gap between the front layer 3 and the back layer 4, the mesh strips of the back layer 4 and the front layer 3 The upturning direction of the mesh bar 1 is the same, so that the two layers of mesh bars are in the same direction. When the oil fume rises, it first enters the mesh bar 1 of the front layer 3, and the oil fume is filtered after adhesion and collision, and then enters the rear layer After the mesh bar 2 of 4 is also filtered, it enters the blower fan and discharges. Compared with the single-layer oil screen, the contact area between the double-layer oil screen and the oil smoke increases, the chance of contact and adhesion increases, and the oil separation degree is significantly improved.

[0026] If the front layer 3 and the back layer 4 are misplaced, the effect is the same as above.

Embodiment 3

[0027] Embodiment 3, as shown in Figure 2-b: the single-layer oil net described in Embodiment 1 is used as the front layer 3, and the right side of the mesh bar 2 of the rear layer 4 is turned up, and the left side is turned upward, so that the oil fume passes through the front layer The mesh bar 1 of 3 changes the direction of oil fume through the mesh bar 2 of rear layer 4, increases the contact chance of oil fume and mesh bar, and improves the oil filtration rate.

Abstract

The invention provides an oil fume filtering method by a metal oil strainer and an easy-cleaning oil strainer adopting the method. The invention is characterized in that the oil strainer can be an one-layer or multi-layer structure; one side of a strainer strip is turned and the other side is raised, and a mould punching shaping is adopted to shape the strainer, and air enters from a side face. If the strainer has a multi-layer structure, the oil strainer has various oil fume filtering methods so as to enhance oil filtering efficiency. The invention not only has elegant appearance, but also can enhance the separation degree of grease, and the air intake and guiding are easy, and both oil-dipping and leaking can be avoided, and the oil strainer cannot be jammed and oil guiding and returning are also quick. And the strainer strips can be easily cleaned. The invention is convenient and practical.

Description

technical field [0001] The invention relates to a method for filtering oil smoke with a metal oil net and an easy-to-clean oil net using the method. In particular, the surface of the mesh bar of the metal oil net is used to guide the oil fume, which is easy to contact and adhere to the mesh bar, thereby efficiently filtering the oil fume, and the oil net is easy to clean. Background technique [0002] At present, the metal oil mesh used on the range hood has a better effect of filtering oil fume and is easy to clean, and only the double-layer oil fume separation plate using "eddy current" technology. But its disadvantage is that the volume is relatively large, and the noise is relatively large, and the air intake is not smooth. This type of oil screen can only be used on near-suction range hoods. If it is used on a top-suction range hood, it is very inconvenient because the volume cannot be reduced, and it also affects the appearance. Now there are many oil screens used o...
