Description

Technical Field

[0001] The utility model relates to a filter screen for a range hood, in particular to a novel filter screen for a range hood used for filtering oil smoke. Background Art

[0002] Currently, most of the plate filters of range hoods use relatively straight holes, which will result in a relatively small contact area between the filter and the oil fume, thus affecting the filtering effect of the oil fume. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a new type of range hood filter, which can effectively solve the problem that the contact area between the filter and the oil smoke is relatively small, thereby affecting the filtering effect of the oil smoke. The oil smoke filtering effect is improved by designing the air guide wall into a special shape and then correspondingly adding oil filter grooves or oil filter blocks, thereby increasing the contact area with the oil smoke. The utility model has the characteristics of simple structure, convenience and practicality.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a novel range hood filter screen, comprising a front filter plate and a rear filter plate that cooperate with each other, characterized in that: the front filter plate and the rear filter plate are both provided with a plurality of ventilation holes, the ventilation holes on the front filter plate and the rear filter plate are staggered, and the ventilation holes are provided with an air guide wall extending inwardly, the air guide wall is special-shaped, and the contact area between the air guide wall and the oil smoke is increased by the special-shaped air guide wall;

[0005] The outer side surface of the air guide wall is provided with a plurality of oil filter grooves or oil filter blocks, the oil filter grooves or the oil filter blocks are all in the shape of long strips, and the oil filter grooves or the oil filter blocks are all arranged horizontally, vertically or obliquely.

[0006] Furthermore, the wind guide wall is provided with a plurality of wave grooves, and the wave grooves are arranged on the inner side of the wind guide wall.

[0007] Furthermore, the wind guide wall is wavy.

[0008] The utility model adopts the above-mentioned technical solution, overcomes the shortcomings of the background technology, and provides a new type of range hood filter, which can effectively solve the problem that the contact area between the filter and the oil fume is relatively small, thereby affecting the filtering effect of the oil fume. The air guide wall is designed to be special-shaped, and the oil filter groove or oil filter block is added accordingly, so that the contact area with the oil fume is increased to improve the oil fume filtering effect. The utility model has the characteristics of simple structure, convenience and practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following descriptions of the embodiments are made with reference to the attached drawings to illustrate specific embodiments in which the present invention may be implemented. The directional terms mentioned in the present invention, such as top, bottom, front, back, left, right, inside, outside, side, etc., are only used with reference to the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention. In the drawings, units with similar structures are represented by the same reference numerals.

[0014] The following further describes the specific implementation modes of the present invention in conjunction with the accompanying drawings to make the technical solutions and beneficial effects of the present invention clearer and more specific.

[0015] See attached Figures 1 to 3 The utility model comprises a front filter plate 1 and a rear filter plate 2 which cooperate with each other, and is characterized in that: a plurality of ventilation holes 3 are arranged on the front filter plate 1 and the rear filter plate 2, and the ventilation holes 3 on the front filter plate 1 and the rear filter plate 2 are staggered, and an air guide wall 4 extending inward is arranged on the ventilation hole 3, and the air guide wall 4 is a special-shaped air guide wall 4, and the contact area with the oil smoke is increased by the special-shaped air guide wall 4;

[0016] The outer side surface of the air guide wall 4 is provided with a plurality of oil filter grooves 5 or oil filter blocks 6, and the oil filter grooves 5 or the oil filter blocks 6 are all in the shape of long strips, and the oil filter grooves 5 or the oil filter blocks 6 are all arranged horizontally, vertically or obliquely.

[0017] Furthermore, a plurality of wave grooves 401 are provided on the wind guide wall 4 , and the wave grooves 401 are provided on the inner side of the wind guide wall 4 .

[0018] Furthermore, the wind guiding wall 4 is wavy.

[0019] When in use, the oil smoke enters from the ventilation hole 3 on the front filter plate 1, first contacts with the wind guide wall 4, and then enters between the front filter plate 1 and the rear filter plate 2. Since the ventilation holes 3 on the front filter plate 1 and the rear filter plate 2 are staggered, the oil smoke will be blocked and diffuse laterally, go around to the other side of the wind guide wall 4, contact with the wave groove 401, the oil filter groove 5 or the oil filter block 6, and finally come out from the ventilation hole 3 on the rear filter plate 2. In this way, the filtering effect of the oil smoke is improved by increasing the contact area between the oil smoke and the filter.

[0020] Oil filter grooves 5 or oil filter blocks 6 can be provided on both the inner and outer sides of the air guide wall 4, so as to increase the area in contact with the oil smoke and further improve the filtering effect of the oil smoke. The oil filter grooves 5 and the oil filter blocks 6 can be provided with only one of them, or the two structures can be mixed and used.
