The air-flow carried from described wind inlet section successively by the first fillter section, have volute casing centrifugal blower fan section, flow equalization section, the second fillter section, and to discharge from described wind outlet section.
As improvement of all pressing noise elimination air-conditioner set of the present invention, described in have volute casing centrifugal blower fan section to comprise motor, draught fan impeller, spiral case, described motor provides driving force for described draught fan impeller, and described draught fan impeller is arranged in described spiral case.
As improvement of all pressing noise elimination air-conditioner set of the present invention, described first fillter section edge is resisted against on the madial wall of described housing, is all had in volute casing centrifugal blower fan section described in entering by the first fillter section to make the air-flow carried from described wind inlet section.
As improvement of all pressing noise elimination air-conditioner set of the present invention, described first fillter section comprises the first air inlet and the first filter screen.
As improvement of all pressing noise elimination air-conditioner set of the present invention, described second fillter section comprises the second air inlet and the second filter screen.
As improvement of all pressing noise elimination air-conditioner set of the present invention, described noise elimination air-conditioner set of all pressing also comprises sub-high efficiency filter section, surface cooling section, bringing-up section and humidifier section.
Compared with prior art, the invention has the beneficial effects as follows: the dust content of air that the present invention all presses noise elimination air-conditioner set can make to be with volute casing centrifugal blower fan section reduces, and available protecting has volute casing centrifugal blower fan section; Meanwhile, through the first fillter section to the filtration of air-flow and combing, make the air draught being with volute casing centrifugal blower fan section even, produce without vortex phenomenon, effectively reduce the noise of volute casing centrifugal blower fan section, and have the operation of volute casing centrifugal blower fan section more stable.
Accompanying drawing explanation
Fig. 1 is floor map of all pressing a detailed description of the invention of noise elimination air-conditioner set of the present invention.
Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, the present invention is described in detail; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection scope of the present invention.
As shown in Figure 1, noise elimination air-conditioner set 100 of all pressing of the present invention comprises:
Housing 10, wind inlet section 20, first fillter section 30, there are volute casing centrifugal blower fan section 40, flow equalization section 50, second fillter section 60 and wind outlet section 70.Described wind inlet section 20, first fillter section 30, volute casing centrifugal blower fan section 40, flow equalization section 50, second fillter section 60 and wind outlet section 70 is had to be set in turn in described housing according to air intake direction, namely the air-flow carried from described wind inlet section 20 successively by the first fillter section 30, have volute casing centrifugal blower fan section 40, flow equalization section 50, second fillter section 60, and to discharge from described wind outlet section 60.
Wherein, first the air-flow carried from described wind inlet section 20 enters in the first fillter section 30 and filters, then enter into downstream have volute casing centrifugal blower fan section 40.Setting like this, the dust content of air being with volute casing centrifugal blower fan section 40 can be made to reduce, and then available protecting downstream has volute casing centrifugal blower fan section 40.This first fillter section 30 comprises the first air inlet and the first filter screen.While air-flow carries out filtering in the first fillter section 30, the noise caused by the first fillter section 30 pairs air-flow is cut down.In addition, enter the air-flow of the first fillter section 30, combing is carried out by the first fillter section 30, thus make the air draught being with volute casing centrifugal blower fan section 40 even further, produce without vortex phenomenon, effectively reduce the noise of volute casing centrifugal blower fan section 40, and have the operation of volute casing centrifugal blower fan section 40 more stable.
In addition, in above-mentioned embodiment, described first fillter section 30 edge is resisted against on the madial wall of described housing 10, thus decrease the flow of the air-flow passed through from the first fillter section 30 edge, all had in volute casing centrifugal blower fan section described in entering by the first fillter section to make the air-flow carried from described wind inlet section.So, filtration and the combing of the first fillter section 30 pairs of air-flows is convenient to.
Further, described in have volute casing centrifugal blower fan section 40 to comprise motor, draught fan impeller, spiral case, described motor provides driving force for described draught fan impeller, and described draught fan impeller is arranged in described spiral case.
Described noise elimination air-conditioner set 100 of all pressing also can comprise sub-high efficiency filter section, surface cooling section, bringing-up section and humidifier section etc., and this each functional section can carry out reasonable combination according to actual needs, introduces no longer in detail herein.
Described second fillter section 60 comprises the second air inlet, the second filter screen.Can carry out secondary filter to from the air-flow having volute casing centrifugal blower fan section 40 to export by this second fillter section 60, the air-flow exported from the second fillter section 60 enters into wind outlet section 60 again.Have described in described flow equalization section 50 is arranged between volute casing centrifugal blower fan section 40 and the second fillter section 60, thus, at air-flow after flow equalization section 50 further combing, then enter into the second fillter section 60.
In sum, the dust content of air that the present invention all presses noise elimination air-conditioner set can make to be with volute casing centrifugal blower fan section reduces, and available protecting has volute casing centrifugal blower fan section; Meanwhile, through the first fillter section to the filtration of air-flow and combing, make the air draught being with volute casing centrifugal blower fan section even, produce without vortex phenomenon, effectively reduce the noise of volute casing centrifugal blower fan section, and have the operation of volute casing centrifugal blower fan section more stable.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
