The oil filtering holes are hexagonal through holes and are uniformly distributed on the filtering area in an array manner.

The oil filtering holes are circular through holes and are uniformly distributed on the filtering area in an array manner.

The convex side of the filtering area is a windward side, and the windward side of the oil filter screen faces the direction of the panel of the range hood for use.

The main disc body is connected with the filtering area through a transition area, the transition area is arranged in an arc arch shape with a high outer part and a low inner part, the highest point of the transition area is higher than the outer surface of the main disc body, the lowest point of the transition area is lower than the lower surface of the main disc body, and the lowest point of the transition area is connected with the outer contour of the filtering area.

The junction of the transition area and the filtering area is provided with an inwards concave oil collecting ring.

The utility model has the advantages that: 1. simple structure, low production cost and improved market competitiveness. 2. The oil filter screen and the main disc body for fixing the oil filter screen are formed by punching a metal plate, so that the process complexity caused by welding operation in the later stage of manufacturing the oil filter screen and the main disc body in a split mode can be avoided, and the production efficiency is low. 3. The integrated punching filter screen has no connecting edge and welding line, and can ensure the safety of users in the using process.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. An integrated formed oil filter screen of a range hood, which is characterized in that: the oil filter comprises a circular main disc body 1 formed by integrally punching and molding a metal plate, wherein a filter area 2 protruding in an arc shape is arranged in the middle of the main disc body 1, a plurality of oil filtering holes 3 are formed in the filter area 2, and the oil filtering holes 3 penetrate through the plate of the filter area 2; a plurality of fixing holes 4 are formed in the main disc body 1 in an annular array mode, and fixing screws penetrate through the fixing holes 4 to fix the oil filter screen on a smoke suction port of the range hood.

The oil filtering holes 3 are hexagonal through holes and are uniformly distributed on the filtering area 2 in an array manner.

The oil filtering holes 3 are circular through holes and are uniformly distributed on the filtering area 2 in an array manner.

The convex side of the filtering area 2 is a windward side, and the windward side of the oil filter screen faces the direction of the panel of the range hood for use.

The main tray body 1 is connected with the filtering area 2 through a transition area 5, the transition area 5 is arranged in an arc arch shape with a high outer part and a low inner part, the highest point of the transition area 5 is higher than the outer surface of the main tray body 1, the lowest point of the transition area is lower than the lower surface of the main tray body 1, and the lowest point of the transition area is connected with the outer contour of the filtering area 2.

And an inwards concave oil collecting ring 6 is arranged at the joint of the transition area 5 and the filtering area 2.

The working principle is as follows: the oil filter screen in the scheme is formed by deeply stretching and integrally punching the same plate, so that the filter area and the main disc body for fixing the filter area can be integrally formed, and the filter area can be installed and used after being formed, thereby avoiding the technical defects of complex process, high production cost and the like of the oil filter screen which needs to be welded integrally in the later period in the traditional split forming technology. In addition, no welding seam exists on the oil filter screen, so that the potential safety hazard that a user is easily scratched when cleaning the oil filter screen in the later period is avoided. In addition, in order to increase the filtering area of the filtering area in a limited area, the filter in the scheme is arranged in an arc-shaped protrusion shape, the protrusion side of the filter is a windward side, and the windward side of the oil filter screen faces the direction of the panel of the range hood for use. Compared with the traditional plane type oil filter screen, the surface area of the protruded oil filtering area is larger, so that more oil filtering holes can be distributed, the wind resistance is reduced, the working efficiency of the range hood is improved, and the range hood can be widely popularized and used.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
