Description
Technical field
The utility model relates to a kind of oil screen of smoke exhaust ventilator device, particularly a kind of double effects oil net arrangement.
Background technology
At present, existing oil smoke machine oil net arrangement divides substantially on the market two classes, one class is that oil guidance column or oil guide groove add fine and close screen pack type, this kind device is because of adopting fine and close screen pack, cause mesh to stop up easily in range hood process on probation, fine and close screen pack is to the Oil Guide poor effect, under the big inadequately situation in oil net angle of inclination, cause greasy dirt directly to drop onto the kitchen range top easily, and volute 5 oil guiding holes 51 place's oil droplets float to oil net outside because of the air intake influence easily along oily net outer surface.Another kind of is double-layer staggered structure, and cranky as double-deck button type oil net air flue, resistance is very big during airflow passes oil net, air-flow has some setbacks, produce very big noise, and air quantity can't promote also, volute 5 oil guiding holes 51 place's oil droplets also drop onto the kitchen range top because of the fuel-displaced net of air intake influence drift easily simultaneously.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of double effects oil net arrangement, and this double effects oil net arrangement filtering oil smoke effect is remarkable, and can prevent effectively that volute oil guiding hole place oil droplet from falling on the kitchen range top.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of double effects oil net arrangement, range hood comprises filter, medium frame plate, air channel and volute, to use direction to be benchmark (being the outside) away from range hood inside one side, filter is positioned at the medium frame plate lower end, the air channel is positioned at medium frame plate upper end and vertically corresponding with filter, volute is located in the air channel, filter comprises one deck outer filter plate and one deck internal layer filter at least at least, wherein the outer filter plate is provided with air vent, described internal layer filter is the entity platy structure of no air vent, and and the outer filter plate between be provided with the air intake gap, this air intake gap is communicated with the air channel, this internal layer filter vertically height lowest part also is provided with oil leaking hole, and when lampblack absorber was started working, oil smoke entered from outer filter plate air vent, during through internal layer filter outer surface, grease has been realized the filtration of oil smoke attached to internal layer filter outer surface in the oil smoke, prevents that oil smoke from entering the air channel and discharging contaminated air; And owing to do not have air vent on the internal layer filter, so can be caught and flow to its vertically height lowest part during volute oil guiding hole place oil droplet drippage by the internal layer filter, enter in the oil trap from the oil leaking hole outflow, avoid oil guiding hole place oil droplet to be subjected to air intake to influence the filter that drifts about out, drop onto on the kitchen range top.
As further improvement of the utility model, the described inside and outside layer filter number of plies is one deck.
As further improvement of the utility model, described internal layer filter be shaped as a kind of in truncated pyramid shape, frustroconical and the flat board.
As further improvement of the utility model, described internal layer filter is fixedly connected on one of outer filter plate upper end, lower end, air channel, medium frame plate lower end and volute lower end and locates.
As further improvement of the utility model, be provided with the air intake gap between described internal layer filter and air channel.
As further improvement of the utility model, the air vent on the described outer filter plate is a kind of in circle, strip, polygon and their combination, and the air vent periphery is provided with inside flange.
As further improvement of the utility model, described internal layer filter is made by one of metal and plastic material.
Useful technique effect of the present utility model is: internal layer filter of the present utility model is an entity structure, and during oil smoke process internal layer filter outer surface, grease has been realized the filtration of oil smoke attached to internal layer filter outer surface in the oil smoke; And owing to do not have air vent on the internal layer filter,, avoid oil guiding hole place oil droplet to be subjected to air intake to influence the fuel-displaced net of drift, drop onto the kitchen range top so can bear the effect of collecting volute oil guiding hole place oil droplet.
