Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

As shown in Figure 1, be the structural representation of the household smoke exhaust ventilator that the embodiment of the present application proposes, comprise shell 1, centrifugal bellows 7, flue 2, primary purifying device 5 and low temp plasma purifier 3; Centrifugal bellows 7 are placed in the inside of shell 1; Centrifugal bellows 7 include casing, air inlet, impeller 6 and air outlet 4; Primary purifying device 5 is arranged at the air inlet of centrifugal bellows; The entrance of low temp plasma purifier 3 connects the air outlet 4 of centrifugal bellows, and the outlet of low temp plasma purifier connects flue 2.

As shown in Figure 1, in the embodiment of the present application, no matter the end portion structure of smoke exhaust ventilator is side-suction type or top suction type, all identical with normal domestic use smoke exhaust ventilator, have the structure such as lubricating cup, filter screen, it will not go into details herein.

During smoke exhaust ventilator work, motor drives the impeller 6 in centrifugal bellows to rotate, rotate the oil smoke of the negative-pressure ward kitchen generation produced first through filter screen, by the air inlet to centrifugal bellows after filter screen filtering and the large molecule smoke particle of interception, by the further filtering of primary purifying device and the large molecule smoke particle of interception, oil smoke is avoided to stick in a large number on the high-field electrode of impeller and follow-up low temp plasma purifier.

Low temp plasma purifier is entered into from the air outlet of centrifugal bellows by filtering and the oil smoke of having tackled large molecule smoke particle, low temp plasma purifier produces high energy electron, Small molecular smoke particle remaining in oil smoke and peculiar smell are broken down into a large amount of free radical isoreactivity material, these active materials can decompose further eliminates Small molecular smoke particle and peculiar smell, and produce not air-polluting water and carbon dioxide with oxygen generation chemical reaction, reach purification further and remove the effect of oil smoke and fumes peculiar smell, fume purifying efficiency is increased to more than 95%, play and significantly reduce oil smoke to the technique effect of air environmental pollution, the high-efficient oil smoke achieving household smoke exhaust ventilator is discharged and purification function, reduce family's oil smoke to the disposal of pollutants of air, also the fumes peculiar smell that user produces when culinary cuisine can be eliminated.

As shown in Figure 2, primary purifying device in the embodiment of the present application is a kind of dynamic rotary filter structure, it is the central portion of impeller 6 coaxial rotating of a kind of and centrifugal bellows, comprise circular periphery 51, the connection network heart 52 and many to be connected between circular periphery and the connection network heart wire 53 radially, diameter wiry is about 0.3mm, component sizes at least can cover the air inlet of centrifugal bellows, when oil smoke enters before impeller is pumped, carry out oil smoke with the filter screen of impeller coaxial rotating to oil smoke to be separated, large molecule smoke particle in filtering oil smoke, avoid oil smoke to stick on impeller and low temp plasma purifier below.The coating of hydrophobic oleophobic can be applied in impeller surface.

Certainly, primary purifying device in the embodiment of the present application is not limited to above-described embodiment, can the purifier of filtering and the large molecule smoke particle of interception, play avoid oil smoke to stick to the device of impeller and low temp plasma purifier below can as the primary purifying device in the embodiment of the present application.
