Abstract
The utility model relates to an extractor hood, belonging to the technical field of household air purifying equipment; the extractor hood comprises a smoke collecting chamber arranged at the lower part of the extractor hood and an air duct arranged at the upper part of the smoke collecting chamber, and an oil gathering net arranged at the inlet of a smoke collecting hood; the extractor hood is characterized in that: an oil inner net is arranged at the air opening of the air duct, and a transition cavity is formed between the oil inner net and the oil gathering net at the inlet of the smoke collecting hood. In the utility model, two groups of the oil nets- which are internally and externally arranged are designed in the extractor hood, the purifying effect is obviously improved after secondary filtration and purification, and the air duct is cleaned without grease contamination.
Description
Technical field
The utility model belongs to the flue gas device for transferring, the technical field of exhaustor for kitchen.
Background technology
The lampblack absorber of existing market is provided with bigger smoke collecting chamber (cover), the oil cleaner screen of external individual layer of exhaust fume collecting hood or multilayer, and the oil smoke that can receive ascension to spread fast, the oil smoke of individual layer oil net only passes through the once filtration of outer oil net, and oil strain is unclean.And the lampblack absorber of existing bilayer or multilayer oil net, the manufacturer often adopts each layer net sheet to be close to, little at interval, unhinderedly filter fast for a large amount of oil smoke, but this design purifying rate is low, thorough filtering oil smoke, and a large amount of oil smoke still accumulates in the air channel, clean very difficulty, also influence attractive in appearance.
Summary of the invention
The utility model purpose is in order to overcome the defective of above-mentioned prior art, and a kind of simple in structure, lampblack absorber structure that purifying rate is high is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of range hood, comprise smoke collecting chamber that is arranged on the bottom and the air channel that is arranged on smoke collecting chamber top, be arranged on the oil-collecting net of exhaust fume collecting hood porch, it is characterized in that air intake vent place, described air channel is provided with interior oily net, forms transitional cavity between the oil-collecting net of interior oily net and exhaust fume collecting hood porch.
Further, described oil-collecting net and interior oily net are the tabular body, and that bows after facing upward before it is with respect to the range hood horizontal plane is obliquely installed, and angle is 0-60 ° between the oil-collecting net of described interior oily net and exhaust fume collecting hood porch.
Angle is 45-60 ° between the oil-collecting net of described interior oily net and exhaust fume collecting hood porch.
For ease of cleaning, the oil-collecting net of described exhaust fume collecting hood porch can be a flat board, is provided with the gap that air feed stream passes through all around.
Described air channel air intake vent also is equipped with in the porous framework body of plastics, the oil smoke adsorbent of built-in nonwoven parcel; Oily net can be a fibrous activated carbon filter screen in described.
Oily net compared to existing technology, the technical solutions of the utility model beneficial effect is: the utility model lampblack absorber has built-in screen pack, form the two filter of two nets effect, make the easier cleaning of external oily net, especially inside, air channel is cleaner for the lampblack absorber inner chamber, thereby prolongs the service life of lampblack absorber, and filtering oil smoke is cleaner, externally exhaust emission reduces, environmental protection.
Description of drawings
Fig. 1 is the utility model lampblack absorber structural representation.
Fig. 2 is Fig. 1 vertical profile diagrammatic sketch.
Fig. 3 is Figure 1A place enlarged drawing
Description of reference numerals: external oily net 1, interior oily net 2, smoke collecting chamber 3, transitional cavity 4, air channel 5.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of range hood as Fig. 1-3, comprise smoke collecting chamber 3 that is arranged on the bottom and the air channel 5 that is arranged on smoke collecting chamber top, be arranged on the external oily net 1 of the external oily net 1 in exhaust fume collecting hood porch, air intake vent place in air channel is interior oily net 2, forms transitional cavity 4 between interior oily net 2 and the external oily net 1.
External oily net 1 and interior oily net 2 are the tabular body, and that bows after facing upward before it is with respect to the range hood horizontal plane is obliquely installed, and forms 60 ° angle between the two.
Oil smoke is purified first via the external oily net 1 of design on smoke collecting chamber 3, the built-in oily net 2 that is designed between transitional cavity 4 and the air channel 5 when entering air channel 5 through transitional cavity 4 again purifies once more, most of grease been separated in external oily net 1 and flows into lubricating cup to be collected, remaining a part of soot particles purifies thoroughly by interior oily net 2
The external oil net of described lampblack absorber adopts plate armature, tentatively with filtering oil smoke, makes grease be adsorbed on the surface of external oil net, and flows in the lubricating cup by the oil circuit of setting and to collect, and its residual grease can be wiped clean easily with cloth.This flat oil net is detachable.
The interior oily net 2 of lampblack absorber is made secondary filter, first road oil net is not filtered clean grease separate once more, thereby make the oil smoke that enters the air channel cleaner, keeps the cleaning in motor, impeller and air channel, increases service life;
Based on spirit of the present utility model, this lampblack absorber also has multiple variation, as smoke collecting chamber 3 porch the multilayer oil net of being close to can be set, and can be flat board, and the air intake gap is arranged all around; The interior oily net 2 of lampblack absorber can be intensive web plate, also can be designed to the web plate of the oil smoke adsorbent of built-in nonwoven parcel, perhaps is fixed on built-in oil smoke adsorbent such as active carbon etc. in the framework in air channel one; Also can be a fibrous activated carbon filter screen, thereby can increase the purifying rate of oil smoke greatly that all this type of all equivalences change, all should be in the claim of the utility model application.
Claims (6)
1, a kind of range hood, comprise smoke collecting chamber that is arranged on the bottom and the air channel that is arranged on smoke collecting chamber top, be arranged on the oil-collecting net of exhaust fume collecting hood porch, it is characterized in that air intake vent place, described air channel is provided with interior oily net, forms transitional cavity between the oil-collecting net of interior oily net and exhaust fume collecting hood porch.
2, range hood as claimed in claim 1, it is characterized in that described oil-collecting net and interior oily net are the tabular body, that bows after facing upward before it is with respect to the range hood horizontal plane is obliquely installed, and angle is 0-60 ° between the oil-collecting net of described interior oily net and exhaust fume collecting hood porch.
