Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a top suction formula lampblack absorber oil cleaner screen mounting structure which characterized in that: the range hood comprises a range hood body 1, wherein a smoke inlet 11 is formed in the lower end of the range hood body 1, an oil filter screen 2 is covered and mounted on the outer end face of the smoke inlet 11, a plurality of positioning buckles 3 are arranged at the front end of the oil filter screen 2, the positioning buckles 3 are clamped on the inner end face of the smoke inlet 11, fixing screws penetrate through positioning holes 4 in the rear end of the oil filter screen 2 and are in threaded connection with the range hood body 1, and the oil filter screen 2 is connected and fixed with the range hood body 1;

the inside incurvature of oil cleaner screen 2 form and lead the smoke chamber, lead the smoke chamber cross-section and set up to the triangle-shaped, including leading smoke limit 21 and vice smoke limit 22, lead and wear to set up a plurality of inlet channel 5 and feed through with smoke inlet 11 in smoke limit 21 and the vice smoke limit 22, lead smoke chamber outline on by oil cleaner screen 2 body bending type upwards forming oil catcher 23, oil catcher 23 rear end runs through oil cleaner screen 2 and sets up a plurality of oil leak 6, oil catcher 23 lower extreme personally submit the slope setting, front end terrain clearance is greater than rear end terrain clearance.

The included angle between the main smoke guiding edge 21 and the auxiliary smoke guiding edge 22 is larger than 90 degrees, and the length of the main smoke guiding edge 21 is larger than that of the auxiliary smoke guiding edge 22.

The intersection of the main smoke guide edge 21 and the auxiliary smoke guide edge 22 is in arc transition.

The upper end of the oil collecting tank 23 is upwards bent by the oil filter screen 2 to form an installation edge 24, the front end of the installation edge 24 is provided with a plurality of positioning buckles 3, and the rear end of the installation edge 24 is provided with a plurality of positioning holes 4 in a penetrating manner.

The main smoke guide edge 21, the auxiliary smoke guide edge 22, the oil collecting groove 23 and the mounting edge 24 are integrally formed by pressing stainless steel materials.

An oil-isolating ring 7 which protrudes upwards is arranged on the back surface of the air inlet groove 5, and the oil-isolating ring 7 is arranged along the outline of the air inlet groove 5.

The working principle is as follows: the range hood starts to absorb oil smoke, and the oil smoke enters the range hood body through the smoke inlet to be extracted. Wherein, the oil strainer is installed to the cover of smoke inlet department, and the inside incurvation of oil strainer forms and leads the cigarette chamber, leads the cigarette chamber cross-section and sets up to the triangle-shaped, leads the cigarette limit including main and vice, and most oil smoke gets into through the air inlet duct on main cigarette limit of leading. When the oil smoke amount is too large, the oil smoke can not be completely absorbed by the main smoke guide edge, and the oil smoke can escape through the auxiliary smoke guide edge, so that the oil smoke can be extracted to the maximum extent, the efficiency and the effect of absorbing the oil smoke are effectively improved, the environmental pollution caused by the oil smoke escaping to a kitchen is avoided, a clean and healthy use environment is provided for a user, and the health of the user is protected.

Wherein, lead on the smoke cavity outline by the oil cleaner screen body upwards bending type formation oil trap, the oil cleaner screen carries out the integral type design with the oil trap, has reduced lampblack absorber spare part, has reduced manufacturing cost. And the lower extreme of oil trap personally submits the slope setting, and front end terrain clearance is greater than rear end terrain clearance for oil cleaner screen installation back, is high before the back low, and inclination generally controls more than 15 for the greasy dirt that gathers in the oil trap can flow from the past backward, finally in the oil cup is gone out to the oil leak hole from the oil trap rear, avoids too much greasy dirt to gather in the oil trap for a long time, is favorable to keeping the inside cleanness of lampblack absorber.

Furthermore, the upper end of the oil collecting tank is upwards bent by the oil filter screen to form a mounting edge, the front end of the mounting edge is provided with a plurality of positioning buckles, the positioning buckles are buckled on the inner end face of the smoke inlet, then the fixing screws penetrate through a plurality of positioning holes formed in the rear end of the mounting edge and are in threaded connection with the range hood body, and the filter screen and the range hood body are fixedly connected. Therefore, compared with the prior art, the oil filter screen can be fixed on the oil filter screen only by installing the fixing screws behind the oil filter screen, so that the installation efficiency is effectively improved. In addition, the mounting edge for mounting the fixing screw is shielded by the oil collecting groove, so that the fixing screw can be hidden outside the use sight of a user, the appearance of the range hood is kept neat and attractive, 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.
