Description
Technical Field
The utility model relates to a lampblack filter device which can be applied to a kitchen range hood.
Background
Cooking fumes and exhaust gases contain a significant amount of oil droplets, VOCs and SVOCs contaminants. The high-temperature oil drops have high viscosity after being cooled and are easy to adhere to an oil guide plate, a filter screen, an inner cavity of the range hood and a fan of the range hood. If the oil is not cleaned in time, oil dirt can be formed after a long time, and the smoke extraction efficiency of the range hood is reduced, so that the escape probability of the oil smoke is increased, and the indoor and atmospheric environments are polluted.
The current common oil fume treatment technology is a static physical filter screen. The static physical filter screen is mainly arranged at the air inlet of the range hood, and the physical collision probability of the oil smoke and the filter screen is improved by increasing the density of the filter screen holes, so that the separation capability of grease is improved. However, after long-term use, grease is easy to block the filter holes, and the air draft resistance is increased. Such publications may refer to the publication of chinese patent application publication No. 201310627017.5, which discloses a filter screen for a range hood (publication No. CN103697510 a), and also refer to the publication of chinese patent application publication No. 201210355913.6, which discloses a concave-convex structure filter screen device for a range hood (publication No. CN102853467 a).
As an improvement, the technician developed a multi-layer screen to increase the level of oil drop entrapment, such as the chinese patent No. ZL201620749859.7, a range hood and screen and deflector filter assembly therefor (issued as CN 205747080U), in which the screen includes sets of front (12) and rear (13) screen surfaces and sets of left (14) and right (15) screen surfaces, the bottom edges of which define horizontally disposed mounting edges (11), each of which is disposed in such a way that the top portions of the screen surfaces converge towards each other.
Similarly, reference may also be made to chinese utility model patent No. ZL201320762013.3, a combined filter screen for range hood (grant publication No. CN 203718864U), in which three different layers of filter screens are used for filtering;
the adoption of the three layers of filter screens can also be referred to in China patent application No. ZL200820166766.7 (issued notice No. CN 201310976Y) and the like.
Recently, some researchers install a rotary filter screen driven by an independent motor at an air inlet of a range hood, and through physical collision between oil fume pollutants and the rotary filter screen, oil drops are intercepted and thrown out under the action of centrifugal force, so that the oil-fat separation effect of the range hood is improved. Chinese patent application No. 200820065337.0 discloses a single-layer centrifugal rotary filter screen disc for use in an air dust purification device. The radial filter screen comprises an outer rim and a central disk, and is connected through a supporting rib, a shaft sleeve which is in plug-in fit with an output shaft of a motor is arranged in the center of the central disk, and a radial filter screen which is formed by a filter screen wire and uniformly distributed along the circumferential direction is arranged between the outer rim and the shaft sleeve. The centrifugal rotary filter screen disk mainly comprises an outer rim and radial supporting ribs, and because the void ratio of the radial tail ends of the supporting ribs is higher, the air resistance is smaller than that of the center of the filter screen disk, the physical collision probability of oil smoke and the filter screen disk is gradually reduced along the outer rim from the center of the filter screen disk, and oil drops and fine particles easily enter the cavity of the range hood through the filter screen.
Further, as disclosed in the chinese patent with application number 201410246649.1, a rotary oil separating filter screen wheel of a range hood is a rotary filter screen with a single-layer structure. The filter screen disk has circular disk body with filtering holes arranged in different radii and punched into connected stepped blade inclined planes. The central hole of the filter screen disk is arranged on the rotating shaft of the screen wheel motor through the sleeve and the knob, and the filter screen disk main body is arranged at the air suction port of the range hood. Because the filter screen holes are formed by flat plate punching, the porosity is lower, the filter screen is easy to form a shielding layer under high-speed rotation, the air inlet resistance is increased, the smoking effect of the range hood is affected, and the noise is extremely large.
