This present device may be completed by a cartridge of a hygroscopic agent intended for promoting the drying of the walls.
6 Claims, 6 Drawing Figures RATENTEI] APR 2 3 597? SHEET 2 OF 2 WALL DRYING DEVICE BACKGROUND OF THE INVENTION The present invention relates to a device for drying walls constructed of any material, by making aeration holes provided with hollow bodies intended for facilitating the circulation of air.
Such hollow bodies, intended for general insertion into openings made in walls in an upwardly inclined plane, or placed in the masonry during construction are known, and certain ones comprise separations determining an air inlet passage and an air outlet passage.
The air inlet passage plces this air in contact with the masonry to be dried, conducting this air to the bottom of the opening while the outlet passage enables the damp air to be evacuated to the outside.
However, these are only air pipes, having no influence on the wall drying process.
There is also a variant where use is made of an axial element separating the tube into two parts, this separating element being provided with openings intended for promoting the rapid evacuation of damp air.
Other devices further facilitate the penetration of the air, by a deflector device promoting the take-up of the outside air and its subsequent circulation in the conduit.
All these devices are partially successful and not perfeet, and their effects are very superficial, as they finally ensure only the admission and evacuation of air, which licks" the inner walls.
SUMMARY OF THE INVENTION The aim of the present invention is to improve such devices by adding thereto an effect of suction of the humidity from the walls.
The invention therefore has for its object a conduit for the aeration and drying of walls, disposed in a blind hole made in the wall, said hole penetrating upwardly into the wall, said conduit being characterized in that it comprises a median longitudinal wall on one side of which are disposed constricting necks forming venturis for the air penetrating into this half-conduit, each venturi being followed by an opening in the wall which communicates the two half-conduits with each other.
This suction of the water contained in the walls, produced by the lowering of pressure due to the venturis, dries a much more considerable zone, hence there is a considerable increase in the radius of action of the device of the invention, and acceleration of the drying process. This present device may be completed by a cartridge of a hygroscopic agent intended for promoting the drying of the walls.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a longitudinal view of a conduit according to the invention;
FIG. 2 is a section along line lI-II of FIG. 1; FIG. 3 is a plan view of the end of the conduit of FIG.
FIG. 4 is a front view of the end of FIG. 3;
FIG. 5 is a plan view of a hygroscopic product support for the conduit according to the invention;
FIG. 6 is a section along line VI-Vl of FIG. 5.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, the conduit for drying walls is composed of one or more tubes 1 assembled end to end and provided with an outer mouthpiece 2, the whole being introduced and sealed in a blind hold penetrating upwardly into the wall.
The tube 1 is perforated with windows 3 so that the air penetrating into the tube comes in contact with the masonry of the wall. The tubes 1 are assembled by male-female fitting, the male part 4 comprising a lug 5 which engages in a notch 6.
Similarly, the mouthpiece 2 fits in the female part of the tube and has a lug 7 engaging in the notch 6.
The tube 1 which is provided with two diametrically opposite grooves 8 receives a median longitudinal sepa rating wall 9 whose edges slide in the two grooves 8. This wall 9 separates the conduit into two halfconduits, one serving for the admission of air, the other for evacuation.
The upper half-conduit which serves for the admission of air comprises constricting necks formed by semi-truncated walls 10 integral with the wall 9 which form venturis for the entering air. These venturis aim at creating zones of reduced pressure which suck the humidity from the wall, the dampened air which is relatively dense because it has been cooled by evaporation of moisture within the wall, then passing into the lower half-conduit through openings 11 made in the wall 9 after each venturi.
The mouthpiece 2 receives a deflector 12 integral with a tube 13 which fits in the mouthpiece where it is held thanks to two studs 14 penetrating into two bayonet grooves 15 of the mouthpiece. This deflector is associated with an air inlet 16 which narrows up to its orifice 17 for outlet to the tubes 1 thus forming a first venturi.
This deflector may be orientable; it is sufficient to replace the notches of the two bayonet grooves 15 by a circular groove in which the lugs 14 can move. When it is desired to complete the air drying action by a hy- 3 adapted to be disposed in a blind hole upwardly penetrating into the wall, comprising a median longitudinal wall dividing the perforated conduit into an upper and a lower half-conduit, both the upper and the lower halfconduit being provided with perforations through which both the upper and the lower helf-conduit communicate directly with the exterior of the conduit and thus with the surrounding wall material to be dried, and a plurality of inwardly tapered sleeves arranged in series in the upper half-conduit, forming venturis for the air penetrating into this half-conduit, each venturi being followed by an opening in the median wall which communicates the two half-conduits with each other.
2. A conduit as claimed in claim 1, wherein the said sleeves are formed by semi-truncated walls integral with the median wall.
3. A conduit as claimed in claim 1 provided with an outer end containing a deflector provided with a semitruncated wall forming a venturi.
4. A conduit as claimed in claim 3, comprising two diametrically opposite inner grooves serving as a slide guide for a removable median wall.
5. A conduit as claimed in claim 3, wherein the deflector is rotatably adjustable.
