Description

A kind of range hood with filtering function
Technical field
The utility model relates to a kind of range hood.
Background technology
At present, restaurant and family kitchen have installed smoke exhaust ventilator mostly, but existing smoke exhaust ventilator is mostly straight-line, just the oil smoke that culinary cuisine produces directly are discharged to outdoor by smoke exhaust ventilator, cause the pollution of ambient atmosphere environment.
Traditional smoke exhaust ventilator, in filtering oil smoke, adopts the mode of oil cleaner screen mostly.Have one deck, two layers or multilayer, filter opening has square, rhombus, circle etc., this oil cleaner screen structure is generally placed on the passage of soot gas circulation of lampblack absorber, when soot gas passes through, oil smoke in gas contacts with screen pack, namely collision rift oil smoke condenses into liquid oil droplet and is attached on screen pack, reaches the object that oil smoke is separated.In order to reduce wind loss, this kind of filter screen structure generally needs larger aperture, the effect that oil smoke is separated will be reduced like this, thus a large amount of greases is accumulated on impeller and spiral case, do not do clean words, the performance of lampblack absorber will be deteriorated, the filter performance of soot gas will decline, and noise during lampblack absorber work also can increase.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of range hood with lampblack filtering function.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of range hood with filtering function, comprise housing, be positioned at the air inlet on housing and air outlet, and be positioned at the spiral case of housing, described spiral case is communicated with air inlet and air outlet forms gas channel, it is characterized in that: the gas channel in described housing between described air inlet and spiral case is provided with net-filter assembly, described net-filter assembly comprises fan and the rotary sieve of coaxial setting, described fan comprises more blades, described rotary sieve has oil strain hole.
Preferably, described rotary sieve is circular, and the oil strain hole on it radially extends along the spaced apart and radial direction along rotary sieve of the circumference of rotary sieve.
In order to obtain better oil strain effect, described oil strain hole is bending curved gradually along the same direction of radial direction from inside to outside along the circumference of rotary sieve of rotary sieve.
In order to discharge liquid oil droplet, be provided with oil drain pan below described rotary sieve and fan, described oil drain pan is match and the disk body of overlapping annular with the periphery of rotary sieve and fan.
Preferably, described fan and rotary sieve set gradually along the airintake direction of the air-flow in gas channel, and described fan and the synchronized rotation of rotary sieve.
In order to ensure the intensity of described rotary sieve, described oil strain hole is distributed with at least two circles along the spaced radial of described rotary sieve.
For the ease of being derived by the oil in oil drain pan, the bottom surface of described oil drain pan tilts to a direction, and the bottom of its bottom surface tilted is provided with oil leaking hole.
Compared with prior art, the utility model has the advantage of that the range hood of this band filtering function not only can make oil smoke be separated the effect playing purifying oil fume, and then make lampblack absorber to realize automatically cleaning, and realizing can improving air quantity, blast again while oil smoke is separated, make the smoke absorption effect of product unaffected, and cost is low, is easy to processing and installs, be easy to realize volume production.

Fig. 1 is the schematic diagram of the range hood of the utility model embodiment.
Fig. 2 is the schematic diagram of the net-filter assembly of the utility model embodiment.
Fig. 3 is the exploded view of the net-filter assembly of the utility model embodiment.
Fig. 4 is the structural representation of the oil drain pan of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As Figure 1-3, the range hood of the utility model embodiment, as shown in Figure 1, comprise housing 1, be positioned at the air inlet 11 on housing 1, and the filter screen be positioned on air inlet or cowling panel, be positioned at the spiral case 2 of housing 1, and the air outlet 12 be positioned on housing 1, spiral case 2 is communicated with described air inlet and air outlet to form gas channel.On gas channel in described housing 1 between this air inlet and spiral case 2, be also provided with net-filter assembly 3.
As shown in Figure 2,3, this net-filter assembly 3 comprises fan 4 and the rotary sieve 5 of coaxial setting, and the direction of its axis and gas channel in the same way.Fan 4 comprises more blades.Rotary sieve 5 has oil strain hole, preferably, as shown in Figure 2,3, this rotary sieve 5 is circular, oil strain hole 51 on rotary sieve 5 is spaced apart along the circumference of rotary sieve, and radially extend along the radial direction of filter screen, and the radial direction same direction from inside to outside along the circumference of rotary sieve 5 of all oil strain holes 51 all along rotary sieve is bending curved gradually, the direction of motion that such structure makes the shape in oil strain hole and liquid oil drop under centrifugal action matches, and makes oil strain better effects if.As shown in Figure 3, oil strain hole 51 on this rotary sieve 5 is at least two circle oil strain holes radially distributed, preferably, as shown in Figure 3, be three circle oil strain holes, the oil strain hole at multi-turn interval is set like this, between the oil strain hole at multi-turn interval, forms reinforcement, the intensity of whole rotary sieve 5 is ensured.Along the air intake direction of wind, be provided with fan 4 and rotary sieve 5 successively, also can be provided with rotary sieve 5 and fan 4 successively, namely the placement order of fan 4 and rotary sieve 5 can be changed.This fan 4 and the coaxial and synchronized rotation of rotary sieve 5.
As shown in Figure 1, this net-filter assembly 3 also comprises one and is positioned at oil drain pan 6 below described fan and rotary sieve 5, and this oil drain pan 6 is the disk body of an annular, as shown in Figure 4, be positioned at the below of rotary sieve 5 and fan 4, match with the periphery of rotary sieve 5 and fan 4 and overlapping.The setting of this fan and rotary sieve 5, namely by collision and centrifugation, the oil droplet in soot gas is purified by centrifugal force separate, and the setting that fan and rotary sieve rotate simultaneously, turn increase air quantity and blast, while being separated oil smoke, not affecting the smoke absorption effect of range hood.Preferably, the inclined bottom surface of this oil drain pan 6 is arranged, and the bottom part of its bottom surface tilted has oil leaking hole 61 for the oil droplet on oil drain pan 6 is directed into lubricating cup.The bottom surface that can be this oil drain pan 6 is overall to a direction inclination, and also can be that this oil drain pan 6 is radially outward-dipping from center, the bottom surface in outside be provided with oil leaking hole.
The range hood of this band filtering function not only can make oil smoke be separated the effect playing purifying oil fume, and then make lampblack absorber to realize automatically cleaning, and realizing can improving air quantity, blast again while oil smoke is separated, make the smoke absorption effect of product unaffected, and cost is low, be easy to processing install, be easy to realize volume production.
Although more than describe in detail preferred embodiment of the present utility model, should be expressly understood that, for a person skilled in the art, the utility model can have various modifications and variations.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
