Description

ELECTRO-OSMOTIC DEVICE
DESCRIPTION
The present patent concerns the devices for dehumidifying rooms in general, and in particular it concerns a new electro-osmotic device for dehumidifying the structures of buildings, walls of buildings, boats, motorhomes, caravans, bungalows, wardrobes or rooms or compartments in general.
The phenomenon of electro-osmosis is known, which is given by the generation of a flow of liquid through the capillary tubes of a non- conductive porous diaphragm, wherein said flow of liquid is generated when a difference in potential is applied to two metal electrodes immersed in the two parts of liquid separated by the diaphragm itself.
The quantity of liquid transferred through the diaphragm is proportional to the difference in potential, independently of the surface of the diaphragm.
Devices are known which use said phenomenon of electro-osmosis for the purpose of dehumidifying the walls of buildings.
The problem of damp in the walls is known, which is due to phenomena of capillary rise of the water present in the soil and results in the capillary penetration of said water in the walls owing to the difference in potential existing between the subsoil and the walls above the ground.
Electro-osmotic devices are known which comprise a positive electrode and a negative electrode connected to the portion of wall to be dehumidified, and wherein electrical voltage is applied to said electrodes and therefore also to said portion of wall to be dehumidified. This causes an inversion of polarity and the inversion of the capillary flow of rising damp, so that water is conveyed downwards, dehumidifying the wall.
Electro-osmotic devices are also known which comprise a positive electrode electrically connected to the building at ground level, a negative electrode electrically connected to the ground surrounding the building, a power supply suited to apply voltage between said two electrodes, and wherein the positive electrode comprises a conductor that, for example, is buried in the cement mortar of the pavement surrounding the building, thus being electrically connected to the walls of the building.
Said applied voltage is generally of at least 5 V, up to a maximum of 12 V. The electro-osmotic devices of the known type thus require continuous energy consumption, even if very low taken as a whole. Furthermore, said devices are maintained in operation even when this is not necessary, with a useless waste of energy.
The installation of said device, furthermore, is not easy and requires chases and raceways for laying the conductor, which leads to relatively high costs.
The problem of humidity and of the formation of condensation in closed environments in general is also known, which for example arises in badly aerated rooms of buildings, for example storerooms, walk-in wardrobes or other types of rooms, or badly insulated rooms like in motorhomes, caravans, bungalows, which furthermore are always located in particularly wet environments, for example at the seaside or near lakes.
In particular, the problem of humidity in boats is known, since these remain immersed in water or located in wet environments for long periods. In order to overcome the above mentioned drawbacks, a new type of electro-osmotic device has been designed and constructed, which is quick to install, free-standing and suited to be used to dehumidify buildings, walls of buildings, boats, motorhomes, caravans, bungalows, wardrobes or rooms or compartments in general.
The main object of the present invention is to provide an electro- osmotic device that is easy and quick to install in any place that needs dehumidifying, even if small.
Another object of the present invention is to provide an electro- osmotic device that can be immediately and easily removed, and that successively can be reused soon.
A further object of the present invention is to provide an electro- osmotic device with compact and reduced size, which is thus easy to transport.
A further object of the present invention is to provide an electro- osmotic device that does not require any power supply and therefore does not involve the continuous consumption of electricity.
These and other direct and complementary objects are achieved by the new electro-osmotic device that is quick to install, free-standing and suited to be used to dehumidify buildings, walls of buildings, boats, motorhomes, caravans, bungalows, wardrobes or rooms or compartments in general.
The new device comprises:
• at least one sealed and tight container with one or more conductive walls, meaning walls made of a conductive material;
• at least one first metallic conductive element, contained in said container and fixed to a first wall or to the bottom of the container, said first wall or bottom being made of a conductive material;
• at least one pair of second metallic conductive elements positioned near each other and near said first metallic conductive element but not in direct contact, and fixed to a second wall or to the cover of the container, said second wall or cover being made of a conductive material,
and wherein said first conductive element and said pair of second conductive elements are completely or partially coated with an acid gel adhering to the surface of the conductive elements, and wherein between said components a difference in potential is generated that charges electrically said conductive walls of the container.
Said container is suited to be positioned in such a way that one or more of its conductive walls is/are in contact with the wall or walls of the room or compartment to be dehumidified and generates static currents that cause the inversion of the capillary rise of water in the walls of the room or compartment to be dehumidified.
Said conductive elements are preferably in the shape of bars or rod irons and are oriented in a direction that is not orthogonal to the walls, the bottom or the cover to which they are constrained. For example, in the preferred solution, said first conductive element is oriented in a direction that is not parallel to the direction of said second conductive elements, wherein said first conductive element and said second conductive elements lie, for example, on different planes that are or are not parallel to one another.
In a further possible embodiment of the invention, even said second conductive elements are parallel or non parallel to each other and lie on the same plane or on different, parallel or non parallel planes. The characteristics of the new electro-osmotic device will be highlighted in greater detail in the following description of the invention, with reference to the drawings that are attached by way of non-limiting example.
Figure 1 shows the inside of the new device (1 ), while Figure 2 shows a horizontal cross section of the new device (1 ).
The new electro-osmotic device (1 ) comprises at least one sealed and tight container (2), cylindrical or prismatic in shape, in turn comprising side walls (21 ) made of a metallic material, preferably aluminium, a bottom (22) and a cover (23) tightly joined to said side walls (21 ). Said bottom (22) and said cover (23) are preferably made of a conductive plastic material, preferably Kevlar ®.
In a possible embodiment of the invention, said bottom (22) and said cover (23), for example, are snap-fitted onto said cylindrical side walls (21 ).
Inside said container (2), the new device (1 ) comprises a first metallic conductive element (3) suited to be constrained to said bottom (22) of the container (2).
Said first metallic conductive element (3) is preferably elongated and cylindrical in shape and made of a conductive bi-component alloy, preferably a copper-silver alloy, for example constituted by 80% copper and 20 % silver. According to the invention, said first metallic conductive element (3) can be made of copper in a silver bath.
Said first conductive element (3), for example, is positioned so that it is not perpendicular to said bottom (22) but has its longitudinal axis (3x) inclined by 3° with respect to the direction orthogonal to the bottom (22).
Inside said container (2) the new device (1 ) comprises also one pair of second metallic conductive elements (41 , 42) constrained to said cover (23) of the container (2), in a position near each other and near said first metallic conductive element (3) but not in direct contact. Said second metallic conductive elements (41 , 42) are preferably elongated and cylindrical in shape and are arranged so that they are not orthogonal to said cover (23) but have their respective longitudinal axes (41 x, 42x) inclined, for example, by 3° with respect to the orthogonal direction.
For example, as shown in the figures, said axis (3x) of the first conductive element (3) is not parallel to said axes (41 x, 42x) of said second conductive elements (41 , 42).
In the example shown in the figures, said axes (41x, 42x) of said second conductive elements (41 , 42) are parallel to each other and lie on a plane that in turn is parallel to the plane on which said axis (3x) of the first conductive element (3) lies.
Said first and said second metallic conductive elements (3, 41 , 42) are preferably distributed with axial symmetry with respect to the longitudinal axis (2x) of the cylindrical container (2).
Said second metallic conductive elements (41 , 42) are preferably made of anodized brass and stainless steel.
Said first and said second metallic conductive elements (3, 41 , 42) are completely or partly coated, preferably completely coated, with at least one layer of acid gel adhering to the surface of the same conductive elements (3, 41 , 42), said acid gel being suited to generate a difference in potential among the components (2, 3, 41 , 42).
The new device (1 ) has compact size and can be easily and rapidly installed in any point of the room or compartment to be dehumidified. In fact, it is sufficient to rest the device (1 ) on the floor or in contact with the walls or parts to be dehumidified.
The operating range of the new device (1 ) is 5-25 metres and it works effectively for a few years.
For example, the dimensions of the new device (1 ) are the following: diameter of the cylindrical container (2): 60 mm or in any case included between 40 and 80 mm; height of the cylindrical container (2): 145 mm or in any case included between 1 15 and 170 mm; diameter of the metallic conductive elements (3, 41 , 42): 8 mm or in any case included between 6 and 10 mm; length of the metallic conductive elements (3, 41 , 42): 125 mm or in any case included between 100 and 150 mm.
Therefore, with reference to the above description and the attached drawings, the following claims are expressed.
