Description
Technical field
The utility model relates to air cleaner apparatus field, particularly relates to the air cleaner adopting centrifugal fan to build fan system.
Background technology
Air cleaner is also known as " air cleaner ", refer to and can adsorb, decompose or transform the product that various air pollutants effectively improve air cleanliness, the air pollution problem inside rooms that the finishing pollution, bacterium, anaphylactogen etc. that are mainly used in solving PM2.5, dust, pollen, peculiar smell, formaldehyde and so on cause.
Existing air cleaner, mainly comprise electric-control system and filtration system and fan system, electric-control system is for controlling fan system work and providing extra additional function, as ozonization, ultraviolet disinfection etc., filtration system is for tackling the contaminant particle of air, and fan system is used for air is blown out via after filtration system.
Existing air cleaner many employings centrifugal fan builds its fan system, and this system includes an air channel cavity body structure and is arranged on a centrifugal fan in this air channel cavity body structure.Along with people improve constantly the user demand of air cleaner, its noise reduction, energy saving requirement are also improved thereupon, also requirements at the higher level are proposed to its fan system.Fan system main noise is the eddy current crack in aerodynamic noise, eddy current crack result from centrifugal fan blade exit place boundary layer separation separation of flow process and gas in the cavity of air channel in diffusion flowing time separation process, comparatively have a strong impact on air-supply effect and comfort.
For this problem, the many employings of prior art arrange sound-absorbing material or increase the method such as silencing means, the method complex structure and with high costs; And the improvement opportunity scheme of whirlpool tongue is to eddy current crack limited efficiency.Therefore air channel cavity body structure is optimized with noise decrease and fan energy consumption, very necessary.
Summary of the invention
The utility model aims to provide the air cleaner that a kind of fan system is optimized, to solve the problem that existing air cleaner noise is large and blower fan energy loss is large.
For solving the problem, concrete scheme is as follows:
Air cleaner, mainly comprises a housing and is arranged on electric-control system in housing and filtration system and fan system; Described fan system includes an air channel cavity body structure and is arranged on a centrifugal fan in this air channel cavity body structure; Described air channel cavity body structure comprises upper cover plate, lower cover and arranges with vertical and chamber, the air channel wall being looped around centrifugal fan periphery, chamber, described air channel wall is not exclusively closed, and be connected to an air outlet, the air outlet wall of described air outlet both sides is stretched out by chamber, air channel wall respectively and is formed respectively, air outlet wall wherein described in side is whirlpool tongue, and the air outlet wall described in opposite side is backboard portion.In the described position closing on whirlpool tongue, the described inner surface of chamber, air channel wall near centrifugal fan axle center outwards protrudes out towards the direction deviating from centrifugal fan axle center, thus forms at least one protuberance.
Further, the inner surface of chamber, described air channel wall outwards protrudes out towards the direction deviating from centrifugal fan axle center in non-tongue position, described whirlpool of closing on, and forms at least one protuberance.
By arranging described protuberance, that air channel cavity body structure is had is little-large-little change, the blade rotation of described centrifugal fan is through protuberance, because air channel cavity becomes suddenly large at this protuberance, cause pressure anticlimax near the cavity inner bulge of air channel, impel eddy current crack to produce in advance, the eddy current just produced by air outlet place and eddy current crack major part are transferred in sealing and soundproof effect better described air channel cavity and produce, thus reach to improve and export and reduce wind and to make an uproar object.It is arranged at the protuberance of the position closing on whirlpool tongue, due to nearest apart from described centrifugal fan outer ring, the air channel cavity change that it brings is the most outstanding, and thus noise reduction is best, it is arranged at the non-position closing on whirlpool tongue and obtains protuberance, then can reduce wind further and make an uproar.
Further, chamber, described air channel wall forms one and above breach, by arranging this breach, improve air channel cavity body structure, form the chamber, air channel of large-little-large change of a volume, impel air whirl and eddy current crack order to produce in the cavity of soundproof effect better air channel in advance, reach and reduce wind and to make an uproar object.
Further, close wall in one of them a formation vertically disposed annular of upper cover plate, lower cover, this annular closed-wall face corresponds to the outer border of this centrifugal fan.By on centrifugal fan below or the two corresponding annular be set close wall, blocked high-speed gas and be trapped in described air channel cavity internal circulation flow passage, reduced howling to reach, reduce blower fan loss object.
Further, described backboard portion adopts outside inclined open type, and described lower cover forms a downhill sections at air outlet position, and corresponding described upper cover plate also forms a downhill sections at air outlet position.Tuyere structure arranges the air outlet design of such descending, and air outlet, further to air-flow guiding, reaches homogenize air-out and reduces the effect of the outflow of noise.
Further, the protuberance of chamber, above-mentioned air channel wall is the protuberance of an arc surface.
Further, chamber, above-mentioned air channel wall is arranged perpendicular to described upper cover plate or described lower cover.
Further, above-mentioned upper cover plate, above-mentioned lower cover all arrange described annular closing face.
Further, chamber, above-mentioned air channel wall forms a breach, and described breach is arranged on the position of the relative side of air outlet.
Air cleaner of the present utility model is by fan system optimal design, and chamber, air channel wall arranges protuberance scheme, reduces the generation of air outlet place airborne noise, optimize gas flow channel in the cavity of air channel, reach reduction noise, reduce blower fan loss, improve the effect of air-out.
