Description
Technical field
The present invention relates to air duct technical fields, and in particular to the mute air duct of low-resistance.
Background technology
Air purifier is also known as air cleaner, air cleaner, clarifier, is to refer to absorption, decompose or convert each
Kind air pollutants (generally comprising finishing pollution, bacterium, anaphylactogen of PM2.5, dust, pollen, peculiar smell, formaldehyde etc etc.),
The product for effectively improving air cleanliness is broadly divided into household, commercialization, industry, building.
Gentle breeze fan (also known as ventilation blower) inside conventional type air purifier makes circulating internal air, the air of pollution
By the way that various pollutants are removed or adsorbed after the air filter (filtering twice) in machine, then by mounted in the negative of air outlet
Ion generator (high pressure when work in anion generator generates negative direct current high voltage), air is constantly ionized, is generated a large amount of
Anion is sent out by gentle breeze fan, forms anion air-flow, achievees the purpose that cleaning, purification air.
The air channel structure of existing air purifier mostly uses greatly following two structures：
One, by the space between the rear cover of air purifier and fan directly as air duct, so that fan is in air draft
Cause purified air that cannot smoothly be discharged to the outside of air purifier without guiding role air in the process, and
But also during air draft, the noise of air purifier is big.
Two, duct type air duct is set in air purifier.Such as Chinese patent literature CN104142013A discloses one kind
The circulation air path of air purifier, including：Air duct main body, the air duct main body have the ventilation shaft of volute type in the shape of a spiral,
In being provided with centrifugal blower and air filter in the air guide duct, it is further opened in the air duct main body and the ventilation duct
The air inlet and air outlet that road communicates；The air filter is oppositely arranged with the air inlet, and is in 10-20 ° of angle.Using
The air duct of duct type can increase the volume and weight of entire air purifier, in order to ensure air output so that air purifier is not
It can realize miniaturization, meanwhile, the air duct of duct type can increase the cost of material, and then increase being manufactured into for air purifier
This.
Therefore, a kind of it is urgent to provide windages small, the small air duct of noise.
Invention content
In order to solve the problems in the existing technology, the utility model provides a kind of simple in structure, reduces windage and makes an uproar
The mute air duct of low-resistance of sound.
Realize that the technical solution of the utility model aim is：
The mute air duct of low-resistance, including air duct ontology, the air inlet being connect with air duct ontology and gas outlet, the air duct sheet
Internal wall is equipped with concaveconvex structure；The concaveconvex structure is bonded in the inner body wall of air duct, and the concaveconvex structure is towards air duct
Position is the round and smooth concaveconvex shape in surface among ontology；Surface layer of the arcuate relief shape towards position among the ontology of air duct is set
There is mineral wool layer.
Further, the concaveconvex shape is symmetrical arranged along air duct inner wall.
Further, the angle between the two neighboring protrusion of the concaveconvex shape is 50-70 °.
Further, the recess portion of the concaveconvex shape uses glass surface layer to fill out for recess portion protrusion.
Further, the height of the recess portion protrusion is low compared with the protrusion of concaveconvex shape.
Further, the angle between the recess portion protrusion and the protrusion of adjacent concaveconvex shape is 140-170 °.
Every same principle product for not departing from the present utility model design also belongs to the scope of protection of the utility model.
The beneficial effects of the utility model are：
The utility model has the advantages of simple structure, and the round and smooth concaveconvex shape in the surface being arranged in the ontology of air duct can postpone air duct
Interior wind pressure, and due to being the round and smooth concaveconvex shape in surface, smaller for the resistance of wind, the pressure loss is small, more efficient.
The utility model in order to further reduce windage, the recess portion of concaveconvex shape use glass surface layer to fill out for recess portion it is convex
It rises, the angle between recess portion protrusion and the protrusion of adjacent concaveconvex shape is 140-170 °, and mineral wool plays the role of inhaling noise, no
But makes windage smaller, almost without windage, not will produce vortex, significantly reduce aerodynamic noise.
Description of the drawings
Fig. 1 is the structural schematic diagram in the mute air duct of low-resistance in the utility model embodiment.
Specific implementation mode
Fig. 1 is to explain the utility model, but the utility model is not limited in range shown in FIG. 1.
As shown in Figure 1, the mute air duct of low-resistance, including air duct ontology 1, the air inlet 2 and outlet being connect with air duct ontology
Mouth 3, the air duct inner body wall are equipped with concaveconvex structure 4；The concaveconvex structure is bonded in the inner body wall of air duct, described recessed
Male structure is the round and smooth concaveconvex shape in surface towards position among the ontology of air duct；The arcuate relief shape is towards in the ontology of air duct
Between position surface layer be equipped with mineral wool layer.
The utility model has the advantages of simple structure, and the round and smooth concaveconvex shape in the surface being arranged in the ontology of air duct can postpone air duct
Interior wind pressure, and due to being the round and smooth concaveconvex shape in surface, smaller for the resistance of wind, the pressure loss is small, more efficient.
The concaveconvex shape of the utility model is symmetrical arranged along air duct inner wall, makes windage smaller in this way.Concaveconvex shape it is adjacent
Angle between two protrusions is 50-70 °.
In order to further reduce windage, the recess portion of concaveconvex shape uses glass surface to fill out for recess portion protrusion 5.And recess portion protrusion
Height compared with concaveconvex shape protrusion it is low.Angle between recess portion protrusion and the protrusion of adjacent concaveconvex shape is 140-170 °.
The utility model in order to further reduce windage, the recess portion of concaveconvex shape use glass surface layer to fill out for recess portion it is convex
It rises, the angle between recess portion protrusion and the protrusion of adjacent concaveconvex shape is 140-170 °, and mineral wool plays the role of inhaling noise, no
But makes windage smaller, almost without windage, not will produce vortex, significantly reduce aerodynamic noise.
The mute air duct of low-resistance of the utility model can be applied to the neck that air purifier, air-conditioning etc. need mute air duct
Domain.
Every same principle product for not departing from the present utility model design also belongs to the scope of protection of the utility model.
Above-described embodiment is only the specific embodiment of the invention, but is not limited to embodiment, all not depart from structure of the present invention
