Description
Technical field
The present invention relates to technical field of central air, particularly relate to a kind of air-conditioner set used without spiral case blower fan direct-connection transmission.
Background technology
For the air-conditioner set used without spiral case blower fan, it generally comprises mixed wind, blower fan, first medium air filtration etc., and the air quantity of this type of air-conditioner set can meet the demands, and the total length of unit is shorter.But owing to being single air intake blower fan without spiral case blower fan, air inlet wind speed is high, and therefore when air-flow is uneven, blower fan easily produces eddy current, noise is large, and time serious, blower fan shook conference and damages damping device, makes system cannot stable operation.
In view of this, for the problems referred to above, be necessary to propose further solution.
Summary of the invention
One is the object of the present invention is to provide all to press noise elimination air-conditioner set, to overcome the deficiency existed in the air-conditioner set of existing use without spiral case blower fan.
For achieving the above object, the one that provides of the present invention all presses noise elimination air-conditioner set, it comprises: housing, wind inlet section, the first fillter section, without spiral case fan section, the second fillter section and wind outlet section, described wind inlet section, the first fillter section, be set in turn in described housing without spiral case fan section, the second fillter section and wind outlet section according to air intake direction;
The air-flow carried from described wind inlet section is successively by the first fillter section, without spiral case fan 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, describedly comprise motor, draught fan impeller without spiral case fan section, described motor provides driving force for described draught fan impeller, and described first fillter section is corresponding with the size without the distance between spiral case fan section and described draught fan impeller.
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, all enters described without in spiral case fan section 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 surface cooling section, bringing-up section and humidifier section.
Compared with prior art, the invention has the beneficial effects as follows: the present invention all presses noise elimination air-conditioner set that the dust content of air entered without spiral case fan section can be made to reduce, and available protecting is without spiral case fan section; Meanwhile, through the first fillter section to the filtration of air-flow and combing, the air draught making to enter without spiral case fan section is even, without vortex phenomenon generation, effectively reduces the noise without spiral case fan section, and more stable without the operation of spiral case fan section.
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, without spiral case fan section 40, second fillter section 50 and wind outlet section 60.Described wind inlet section 20, first fillter section 30, be set in turn in described housing 10 without spiral case fan section 40, second fillter section 50 and wind outlet section 60 according to air intake direction, namely the air-flow carried from described wind inlet section 20 successively by the first fillter section 30, without spiral case fan section 40, second fillter section 50, and 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 without spiral case fan section 40.Setting like this, can make the dust content of air entered without spiral case fan section 40 reduce, so available protecting downstream without spiral case 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, carried out combing by the first fillter section 30, thus make the air draught that enters without spiral case fan section even further, produce without vortex phenomenon, effectively reduce the noise without spiral case fan section, and more stable without the operation of spiral case fan section.
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 enter described without in spiral case fan section 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, describedly comprise motor, draught fan impeller without spiral case fan section 40, described motor provides driving force for described draught fan impeller, described first fillter section is corresponding with the size without the distance between spiral case fan section and described draught fan impeller, and namely the first fillter section and the described distance without spiral case fan section 40 entrance are determined according to described draught fan impeller size.
Described noise elimination air-conditioner set 100 of all pressing also comprises 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 50 comprises the second air inlet and the second filter screen.Can carry out secondary filter to from the air-flow exported without spiral case fan section 40 by this second fillter section 50, the air-flow exported from the second fillter section 50 enters into wind outlet section 60 again.
In sum, the present invention all presses noise elimination air-conditioner set that the dust content of air entered without spiral case fan section can be made to reduce, and available protecting is without spiral case fan section; Meanwhile, through the first fillter section to the filtration of air-flow and combing, the air draught making to enter without spiral case fan section is even, without vortex phenomenon generation, effectively reduces the noise without spiral case fan section, and more stable without the operation of spiral case fan section.
