Abstract
The utility model provides a pipeline for an air exchange fan, the outdoor end of the pipeline is connected with an outdoor pipeline cover, the indoor end of the pipeline is connected with an indoor air exchange fan, and a waterproof rib is arranged on the inner wall of the pipeline. The utility model has the advantages that the pipeline can prevent impurity and rainwater entering into the pipeline, and can also automatically discharge after the impurity and the rainwater enter into the pipeline.
Description
Technical field
The utility model relates to a kind of ventilation fan, particularly about a kind of used in air exchange fan pipeline.
Background technique
Ventilation fan 100 is a kind of common ventilation ventilation equipment, as shown in Figure 1.Usually with one or two pipelines 10, the ventilation fan 100 in its outdoor end 12 junction chamber outer tube drive caps 200, indoor end 11 junction chambers ventilates indoor and outdoor.Above-mentioned pipeline 10 normally flatly is installed between indoor ventilation fan 100 and the piping outside the house lid 200.When raining and having when blowing to indoor wind, rainwater can when serious, can flow backward to indoor from duct cap 200 flow ipes 10.Sometimes indoor even without flowing back to, but the water that accumulates in the pipeline can cause that also pipeline is mouldy.
The content of model utility
Main purpose of the present utility model is to provide a kind of pipeline of used in air exchange fan, can prevent in rainwater or the foreign matter inlet chamber;
Secondary objective of the present utility model is to provide a kind of pipeline of used in air exchange fan, can prevent from that rainwater or foreign matter from entering to accumulate in the pipeline, and with its discharge.
For achieving the above object, the utility model provides a kind of pipeline of used in air exchange fan, and the ventilation fan in its outdoor end junction chamber outer tube drive cap, indoor end junction chamber is provided with waterproof rib at described inner-walls of duct.
Described waterproof rib is positioned at one side of inner-walls of duct, and is horizontal.
Described waterproof rib be positioned at inner-walls of duct around, in the form of a ring.
The bottom of described indoor end is higher than the bottom of described outdoor end.
The diameter of described indoor end pipeline is less than the diameter of described outdoor end pipeline.
Described pipeline is " Z " shape.
Described indoor end is divided into three sections successively to outdoor end: The initial segment, linkage section, outlet section, linkage section forms waterproof rib.
The waterproof rib of described inner-walls of duct is a smooth surface to the surface of outdoor end.
Advantage of the present utility model is both can prevent that foreign matter and rainwater from entering the pipeline depths, also can be automatically with its discharge after foreign matter and rainwater enter pipeline.

Embodiment
As shown in Figure 2, be the utility model first embodiment's schematic representation.Ventilation fan in the outdoor end 12 junction chamber outer tube drive caps of pipeline 10, indoor end 11 junction chambers, to outdoor end 12, the diameter of pipeline 10 is identical from indoor end 11.The utility model wall within it is provided with horizontal waterproof rib 300.Therefore after the installation, waterproof rib 300 is positioned at duct bottom, can effectively stop water to enter the pipeline depths, thereby it is indoor to prevent that rainwater from flowing back to, to guarantee indoor dry and comfortable and life-span of improving product.
As shown in Figure 3, be the utility model second embodiment's schematic representation.For further facilitating installation, the waterproof rib 300 of present embodiment be positioned at inner-walls of duct around, in the form of a ring, and adopt smooth surface to the surface of outdoor end 12 at indoor end 11.Also pipeline 10 is installed obliquely, made the bottom of indoor end 11 be higher than the bottom of outdoor end 12.So no matter pipeline is installed with which kind of direction, and the bottom of inner-walls of duct all has and prevents that rainwater from blowing back into indoor waterproof rib 300, can effectively play waterproof effect.And,, also can under the effect of gravity, also be difficult to gather, and can discharge automatically owing to indoor end 11 adopts smooth surface to the surface of outdoor end 12 even therefore have rainwater or foreign matter to enter once in a while in the pipeline because pipeline 10 is to tilt to install.
As shown in Figure 4, be the utility model the 3rd embodiment's schematic representation.Be different with second embodiment, the diameter of indoor end 11 pipelines of pipeline 10 is less than the diameter of outdoor end 12 pipelines, and it is horn-like that integral body is.Still around inner-walls of duct, establish ring-type waterproof rib (not shown) with second embodiment.Like this, no matter pipeline 10 levels are installed or tilted installation, the bottom of indoor end 11 still can be higher than the bottom of outdoor end 12, has realized the skewed of inner-walls of duct so too, therefore enter rainwater or foreign matter in the pipeline once in a while, under the effect of gravity, can discharge automatically.
As shown in Figure 5, be the utility model the 4th embodiment's schematic representation.Pipeline 10 integral body are " Z " shape, the ventilation fan 100 in indoor end 11 junction chambers, and outdoor end 12 junction chamber outer tube drive caps 200 are divided into three sections from indoor end 11 to outdoor end 12: the The initial segment 13 of level, vertical linkage section 14, horizontal outlet section 15 successively.Because linkage section 14 is vertical shape, is equivalent to waterproof rib, therefore enter rainwater or foreign matter in the pipeline once in a while, can't enter the depths of pipeline, thereby guarantee the dry and comfortable of indoor and pipeline.
