In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.
As shown in fig. 1 to 3, a filter screen assembly 10 according to an embodiment of the first aspect of the present invention includes a filter screen layer 100, a grease-adsorbing layer 200, and a fixed net frame 300, wherein the filter screen layer 100 is provided with a plurality of filter holes 110, the fixed net frame 300 is used as an assembly chassis, and both the filter screen layer 100 and the fixed net frame 300 are sheet metal parts and can be used repeatedly; grease adsorbed layer 200 can select to be the filter pulp layer, and it mainly comprises the filter pulp, the filter pulp includes but not limited to synthetic fiber filter pulp, non-woven fabrics filter pulp, glass fiber filter pulp and active carbon filter pulp, the filter pulp has good adsorption efficiency to the grease, but can not used repeatedly, needs to change according to the length of service.
In order to facilitate replacement of the grease adsorption layer 200, an installation clip 400 is arranged on the edge of the filter screen layer 100, the installation clip 400 is provided with an insertion hole 420, the edge of the grease adsorption layer 200 and the edge of the fixed net rack 300 are inserted into the installation clip 400 through the insertion hole 420, and the grease adsorption layer 200 is located between the filter screen layer 100 and the fixed net rack 300. Since the grease-adsorbing layer 200 is a soft layer and the filter screen layer 100 and the fixed net mount 300 are both made of sheet metal, the grease-adsorbing layer 200 needs to be clamped to the filter screen layer 100 by the fixed net mount 300. When needing to be changed during the grease adsorbed layer 200, only need follow fixed net rack 300 and old grease adsorbed layer 200 extract in the installation screens 400 to replace old grease adsorbed layer 200 with new grease adsorbed layer 200, at last again with fixed net rack 300 and new grease adsorbed layer 200 reinsert to in the installation screens 400, can accomplish the change of grease adsorbed layer 200.
Since the filter screen of the existing range hood is generally rectangular, in this embodiment, the filter screen layer 100, the grease adsorption layer 200, and the fixed net frame 300 are all rectangular, specifically, the three edges of the filter screen layer 100 are all provided with the bending plates 410, and all the bending plates 410 are bent toward the inner side of the filter screen layer 100, so that all the bending plates 410 form the installation clamping position 400 together, and at this time, the insertion opening 420 is arranged on the edge without the bending plates 410; because the grease absorption layer 200 and the fixed net rack 300 are both disposed in the installation position-limiting location 400 by means of plugging, the sizes of the two should be within the size-receivable range of the installation position-limiting location 400. It can be understood that the bending plates 410 may also be respectively disposed on any pair of intersecting edges of the filter screen layer 100, and in this case, the installation clamp 400 has two insertion openings 420, and both of the above two embodiments can limit the long and short edges of the grease absorption layer 200 and the fixed net rack 300, so that both of the above two embodiments belong to the same technical solution.
In other embodiments, however, the filter screen layer 100, the grease adsorption layer 200 and the fixed net rack 300 are all circular, specifically, a plurality of bending plates 410 are arranged on one semicircular edge of the filter screen layer 100, and all the bending plates 410 are bent towards the inner side of the filter screen layer 100, so that all the bending plates 410 together form the installation clamp 400, and at this time, the insertion opening 420 is arranged on the other semicircular edge of the filter screen layer 100; because the grease absorption layer 200 and the fixed net rack 300 are both disposed in the installation position-limiting location 400 by means of plugging, the sizes of the two should be within the size-receivable range of the installation position-limiting location 400. Since the fixed net frame 300 is a sheet metal member, it is difficult to deform, and once the coverage of the installation position 400 exceeds half of the filter screen layer 100, it is difficult to insert the fixed net frame 300 into the installation position 400.
