[0001] The present invention refers to a method and a device for dehumidifying the structure
of a building.
[0002] In particular, the present invention concerns a method and a device adapted to reduce
or eliminate rising damp inside buildings.
[0003] The problem of humidity inside buildings, in particular on the lower floors, creating
discomfort for the inhabitants or occupants of these floors, has been known for some
time.
[0004] Said humidity is usually due to the contact of non damp-proofed walls with the ground.
The lack of damp-proofing of the walls allows the water present in the ground to penetrate
into the bricks and rise along the walls at different heights, by means of capillarity.
The terms used to refer to this phenomenon are rising damp or capillary moisture.
[0005] The rising is due to the presence of a difference in potential between the subsoil
and the walls above the ground.
[0006] Solutions exist to remedy this type of problem, for example chemical products or
special paints for application on the walls.
[0007] This type of solution does not fully satisfy the needs of the users as it provides
a temporary solution to the problem of humidity, and also because it introduces chemical
substances into the environment to be treated.
[0008] Other solutions proposed are so-called polarity inversion solutions, involving an
electro-osmotic device. Said devices act on the difference in potential to limit rising
of the water up the walls.
[0009] The application
WO 2015/036873 describes such an electro-osmotic device, which comprises a sealed container inside
which a first metallic conductive element and a pair of second metallic conductive
elements are arranged, the first and the second metallic elements being coated with
an acid gel.
[0010] This solution therefore does not solve the problem of the use of chemical substances.
Furthermore, to dehumidify an environment, the above-mentioned device must be placed
in contact with a wall of the environment.
[0011] The application
WO 2016/055969 describes a further example of wall dehumidification system in which there is the
generation of an impulsive magnetic or electromagnetic field directed onto the wall
structure to be dehumidified.
[0012] However, said system requires electrical power supply means for a generator adapted
to generate said impulsive magnetic or electromagnetic field.
[0013] The object of the present invention is to propose a method and a device for dehumidifying
the structure of a building which is effective and which functions without the aid
of chemical substances, or the need to resort to electrical power supply.
[0014] A further object of the invention is to provide a device for dehumidifying the structure
of a building which can be arranged in any position.
[0015] These and further objects, which will be evident to a person skilled in the art,
are achieved by a method and a device for dehumidifying the structure of a building
produced according to the technical teachings of the attached claims.
[0016] Advantageously the method for dehumidifying the structure of a building entails capturing
electromagnetic waves resulting from interferences created by electric charges due
to the humidity, and emitting the electromagnetic waves phase-shifted by 180°.
[0017] Analogously the device for dehumidifying the structure of a building comprises an
outer container and an inner member. The inner member comprises at least one capturing
element adapted to capture electromagnetic waves resulting from interferences created
by electric charges due to the humidity and directed along a first axis, and at least
one reflection element, adapted to reflect and emit the electromagnetic waves phase-shifted
by 180°, connected to the capturing element and directed along a second axis inclined
with respect to the first axis.
[0018] Further characteristics and advantages of the invention will become evident from
the description of a preferred but not exclusive embodiment of the device for dehumidifying
the structure of a building, illustrated by way of non-limiting example in the accompanying
drawings, in which:
figure 1 is a perspective and exploded view of the device for dehumidifying the structure
of a building;
figure 2 is a transparent front view of the device of figure 1.
[0019] With reference to the figures cited, a device for dehumidifying the structure of
a building is shown.
[0020] The device comprises an outer container (not illustrated) and an inner member 1 (figures
1 and 2).
[0021] According to the invention the inner member 1 comprises at least one capturing element
2, adapted to capture electromagnetic waves resulting from interferences created by
electric charges due to the humidity and oriented along a first axis (A), and at least
one reflection element 3, adapted to reflect the electromagnetic waves and re-transmit
them phase-shifted by 180°. The reflection element 3 is connected to the capturing
element 2, and is oriented along a second axis (B) arranged inclined with respect
to the first axis (A).
[0022] The device according to the invention exploits a known physical principle, i.e. the
principle according to which two opposite waves with equal energy cancel each other
out.
[0023] The device 1 therefore permits cancellation of the electromagnetic waves due to the
humidity, which raise the zero electric potential line (i.e. the area where there
are no electric charges) above the floor of the environment to be dehumidified. Cancellation
of the above-mentioned electromagnetic waves causes a lowering of the zero electric
potential line below the floor, and therefore cancellation of the difference in potential
in the walls, which is at the origin of the phenomenon of rising damp. In the absence
of this difference in potential there are no manifestations of humidity due to rising
damp.
[0024] To obtain the best results, it is preferable for the second axis (B) to be perpendicular
to the first axis (A).
[0025] In the preferred embodiment of the invention, the inner member 1 comprises a main
body 4 and at least one lateral body 5 which is fixed directly to the main body 4
(figure 1). The capturing element 2 is arranged in the main body 4. Preferably the
latter has an elongated form which extends along the first axis A.
[0026] More preferably the capturing element 2 is arranged at one end of the main body 4
(figures 1 and 2).
[0027] According to another preferred embodiment, the reflection element 3 is arranged in
the lateral body 5, even more preferably at one end of the lateral body 5.
[0028] It is advantageous for the lateral body 5 to extend along the second axis B. It follows
that the lateral body 5 is laterally connected to the main body 4 and has one of its
ends in contact with said main body 4.
[0029] Preferably the reflection element 3 is arranged at the end of the lateral body 5
which is connected to the main body 4.
[0030] In the preferred embodiment, illustrated in the attached figures, the inner member
1 comprises two lateral bodies 5 which each comprise a reflection element 3.
[0031] In the example illustrated the two lateral bodies 5 have an elongated shape extending
perpendicularly to the axis A, and having a cross shape. Said lateral bodies 5 are
illustrated in an intermediate position between the two ends of the main body 4, preferably
substantially central.
[0032] It is advantageous for the inner member 1 to comprise two capturing elements 2, each
being arranged at a respective end of the main body 4, and two reflection elements
3, each being arranged in a respective lateral body 5, in the area of the end connected
to the main body 4, as shown in the figures.
[0033] The inner device 1 is preferably made of a conductive material, even more preferably
copper. The main body 4 and the lateral bodies 5 that compose it are illustrated by
a cylindrical shape, i.e. circular cross section. However, the section can have any
shape.
[0034] The capturing element 2 and the reflection element 3 are structurally similar and
comprise a recess made in the main body 4 and in the lateral body 5, respectively.
[0035] They have a cylindrical first portion 20, 30, a second frustoconical portion 21,
31 and a third cylindrical portion 22, 32 with diameter smaller than the diameter
of the first portion 20, 30. The first, the second and the third portion 20, 21, 22,
30, 31, 32 are advantageously coaxial (figure 2). Obviously the second frustoconical
portion 21, 31 narrows from the first portion 20, 30 to the third portion 22, 32.
[0036] Preferably, going from the end of the main body 4, or the lateral body 5, towards
the inside thereof, the capturing element 2 or the reflection element 5 has a decreasing
diameter.
[0037] As can be seen in the figures, the first portion 20, 30 of the capturing element
2 and the reflection element 3 is arranged at the end of the main body 4 and lateral
body 5, respectively.
[0038] It should also be noted that the lateral bodies 5 comprise an axial through hole
50 adapted to permit the insertion of a fastening member for fastening thereof to
the main body 4. The axial through hole 50 is made along the axis B and as such is
in the extension of the third portion 32 of the reflection element.
[0039] In the example illustrated, the fastening member is a screw 6 (figure 1), and therefore
the axial through holes 50 are internally threaded. The main body 4 also comprises
a transverse through hole 40 which extends parallel to the axis A, so as to fix both
the lateral bodies 5 with one single screw 6. It can be seen that the screw 6 passes
axially through the reflection elements 3. Preferably the screw 6 is made of conductive
material, even more preferably of copper.
[0040] In the preferred embodiment, the main body 4, which has a cylindrical shape, has
a length of 12.5 cm and a diameter of 14 mm, while the lateral bodies 5, also cylindrical,
have a length of 26 mm and a diameter of 14 mm. The screw 6 and the through holes
40, 50 have a diameter of 4 mm.
[0041] The device 1 further comprises an outer container (not illustrated in the figures)
in which the main body 4 and the lateral bodies 5 are inserted.
[0042] The outer container comprises a parallelepipedal body, preferably made of aluminium,
and two covers shaped for closing the container, the covers being preferably made
of a plastic material, for example PVC.
[0043] The parallelepipedal body advantageously comprises two smooth faces and two faces
with rough surface.
[0044] The main body 4 is fixed in use to one of the two covers, preferably the upper one,
by means of a second fastening member 7.
[0045] In the example illustrated, the second fastening member comprises a screw (figure
1), preferably made of a conductive material, even more preferably of copper. The
main body 4 comprises an axiascrew 7. Said axial hole 41 extends from the bottom of
one of the capturing elements 2, along the axis A and into the extension of the third
portion 22 of the same capturing element 2 (figure 2).
[0046] The outer container has dimensions in the order of 20 cm height, 10.5 cm width and
5 cm depth. Preferably the faces with dimension 20 x 10.5 are smooth, whereas those
with dimension 20 x 5 have rough surfaces.
[0047] Operation of the invention appears evident to a person skilled in the art from what
has been described and in particular is as follows.
[0048] The inner member 1 is assembled by fixing the lateral bodies 5 to the main body 4
by means of the screw 6, inserting it through the through holes 40, 50.
[0049] The inner member 1 is then fixed to one of the covers of the outer container, by
means of the second screw 7.
[0050] The inner member 1 is then inserted inside the outer container, which is then closed
by means of the two covers.
[0051] The device according to the invention, thus assembled, is arranged in an environment
in which there is rising damp.
[0052] The electromagnetic waves at the origin of the humidity enter the inner member 1
through the capturing elements 2 and are then channelled towards the reflection elements
3.
[0053] The waves then penetrate the reflection elements 3 and are reflected and emitted
to the outside phase-shifted by 180°.
[0054] The protection also comprises a method for dehumidifying the structure of a building,
comprising the steps of capturing electromagnetic waves resulting from interferences
created by electric charges due to the humidity, and re-transmitting the electromagnetic
waves phase-shifted by 180°.
[0055] The device and the method described above permit dehumidification of the structure
of a building naturally (no chemical substance is used) and reversibly (the original
humidity can be re-established by simply removing the device from the dehumidified
environment).
