Description
Technical field
The utility model relates to field of kitchen electric appliance equipment, especially relates to the range hood that a kind of oil-filtering apparatus and application have this oil-filtering apparatus.
Background technology
Range hood is able to widely used electric equipment in kitchen, for discharging the oil smoke produced in cooking stove cooking process.In mist extractor process, oil smoke carries out the process of Oil-gas Separation at the filter screen place of range hood, directly enters air pollute to avoid oil-containing gases, in this process, oil gas is through at least one metafiltration net, and oil droplet condenses on filter screen, and is dropped in after water conservancy diversion in the lubricating cup below filter screen.But, current range hood filter screen is owing to being fixed, and in oil smoke uphill process, a part of oil-containing gases directly passes and cannot come in contact with filter screen from the mesh of filter screen, cause the oil molecule in this part oil gas to be adsorbed in screen surface, therefore its filter effect is not good enough.In addition, when oil droplet is attached on filter screen, due to the viscosity between oil droplet and filter screen, the oil droplet that diameter is less is difficult to drip in lubricating cup along filter screen, and the time freezes solidly on filter screen once long, is difficult to remove.
In order to improve oil strain effect, mechanical type filter screen general at present, mainly through increasing the contact area with oil smoke, increases collision probability and is separated, filters oil smoke such as various revolving filter screen.If application number is " rotary filter screen of rang hood " disclosed in the Chinese invention patent application of 201110170306.8 (application publication number is CN 102331019 A), this rotary filter screen comprises a conical guard, two central bearings respectively establishing an axis body be connected with rack with range hood oil cup to match of port up and down of guard, bearing is connected to guard by the support of bearing.Although, this filter screen can when range hood works slow circumvolve, thus oil gas is fully contacted with filter screen, to improve oil gas separation, and the whereabouts difficulty of the less oil droplet of diameter on filter screen can be reduced, thus improve the cleannes of filter screen, but, this rotary sieve needs other provided with fan, and the flabellum of the air propels filter screen that fan produces slowly rotates, and overall structure is comparatively complicated.In addition, and for example application number is the method for grit " in a kind of rotary sieve and the filtering air " disclosed in the Chinese invention patent application of 201410190899.8 (application publication number is CN 104001388 A), when air passes through the dish type fan of this rotary sieve, the filament of filter screen catches the grit in air, grit throws away to surrounding under the influence of centrifugal force and falls into dust collect plant, the air of filtering is discharged along the axis of dish type fan, filter efficiency is good and filter dirt precision is high, but this rotary sieve not only structure is comparatively complicated, nor is applicable to range hood.Although above-mentioned existing rotary filter screen increases the collision probability with oil smoke, but also bring resistance to increase rapidly thereupon, the negative consequence that air quantity reduces, and, because the oil smoke be inhaled into can not reduce through filter screen temperature, thus the collision rift of oil smoke and filter screen, can not be condensed into oil droplet and be adsorbed on filter screen, makes grease discharge value often be difficult to meet range hood Energy Efficiency Standard.
