An oil filter device and a range hood using the device

Abstract

An oil filter device comprises a framework and an oil filter assembly arranged on the framework, and is characterized in that the framework is provided with a condensing liquid influx and a condensing liquid outflux; a first pipeline provided for a condensing liquid to flow through is formed inside the framework; the oil filter assembly is provided with a second pipeline provided for the condensing liquid to flow through and communicated with the first pipeline; and the first pipeline and the second pipeline together constitute a connecting channel between the condensing liquid influx and the condensing liquid outflux. The invention also discloses a range hood applying the oil filter device. The oil filter device and the range hood have the advantages that the condensing liquid produced from a condensing unit flows in through the condensing liquid influx, flows through the first pipeline and the second pipeline and then flows out from the condensing liquid outflux, the temperature of the oil filter assembly can be lowered to 0 DEG C or less, cooking fumes are rapidly condensed into oil droplets on the surface of the oil filter assembly when passing through the oil filter assembly, and thus the oil filtering effect is improved; and when the range hood adopting the oil filter device works, the cooking fume emissions are significantly reduced, and the cooking fume sucking effect is significantly improved.

Description

technical field [0001] The invention relates to kitchen electrical equipment, in particular to an oil filter device and a range hood using the oil filter device. Background technique [0002] The range hood is an electrical device widely used in the kitchen, which is used to exhaust the oily fumes generated during the cooking process of the stove. In the process of oil fume exhaust, the oil fume is separated from the oil and gas at the filter screen of the range hood, so as to avoid the oily gas directly discharged into the atmosphere and cause pollution. net, and drip into the oil cup below the strainer after diversion. However, because the filter screen of the current range hood is fixed, a part of the oil-containing gas directly passes through the mesh holes of the filter screen and cannot contact the filter screen during the rising process of the oil fume, causing the oil in this part of the oil gas to Molecules cannot be adsorbed on the surface of the filter, so its f...

Problems solved by technology

Although, the filter screen can rotate slowly when the range hood is working, so that the oil and gas can fully contact with the filter screen to improve the separation effect of oil and gas, and can reduce the difficulty of falling oil droplets on the filter screen with a smaller diameter, thereby improving the filter screen. cleanliness, however, the rotary filter requires an additional fan, the airflow generated by the fan pushes the fan blades of the filter to rotate slowly, and the overall structure is relatively complicated

In addition, as disclosed in the Chinese invention patent application whose application number is 201410190899.8 (the application publication number is CN 104001388 A), "A Rotary Filter Screen and a Method for Filtering Dust Particles in the Air", when the air passes through the rotating filter screen, When the disc fan is used, the wires of the filter screen capture the dust particles in the air, and the dust particles are thrown out to the surroundings and fall into the dust collection device under the action of centrifugal force. The filtered air is discharged along the axial direction of the disc fan, and the filtration efficiency is good. And the dust filtering precision is high, but the structure of the rotary filter screen is not only complicated, but also not suitable for range hoods

Although the above-mentioned existing rotary filter screen increases the collision probability with the oil fume, it also brings the adverse consequences of a rapid increase in resistance and a decrease in the air volume. , so after the oil fume collides with the filter screen, it will not condense into oil droplets and be adsorbed on the filter screen, making the oil emission value often difficult to meet the energy efficiency standard of range hoods
