  • a load of hygroscopic product said load being replaceable and being constituted by a rigid cell containing a hygroscopic product, said cell being provided with openings for the circulation of air and, in a lower area, with holes for liquid runoff;
  • a tank located under the load of hygroscopic product, said tank being closed superiorly by an upper face that forms a collecting surface to collect the liquid that falls by gravity from the load of hygroscopic product, said upper face of the tank being open in a conduit of entry that flows into the interior of the tank;
  • a cover that separates the load of the hygroscopic product and the upper face of the tank from the outside, said cover being provided with air passages for the circulation of ambient air.

  • Portable dehumidifying devices of this type are commonly used to dehumidify damp and poorly ventilated spaces, such as bathrooms, garages, warehouses, etc.
  • the principle of operation of these devices is that the ambient air comes into contact with the hygroscopic product (typically calcium chloride in crystalline form), which thanks to its hygroscopic properties retain moisture from the air, forming a brine that falls by gravity into the tank within said hygroscopic product. This process remains operative while hygroscopic product remains in the housing.
  • the hygroscopic product typically calcium chloride in crystalline form
  • the device is designed so as to minimize the risk of spillage of brine to the outside in case of accidental overturning.
  • This function is performed by the upper face of the tank, which closes the tank superiorly forming a collecting surface to collect the brine that falls from the load of hygroscopic product, as well as the inlet duct that does not allow the brine to exit through it overturned position or in a turned position of the device.
  • WO2006010554A1 describes a portable dehumidifier device of the type indicated in the principle, with the difference that the charge of replaceable hygroscopic product is not constituted by a rigid cell containing the hygroscopic product, but by a package of hygroscopic product formed by a granulated content in a closed bag that is usually nonwoven.
  • the hygroscopic product package is introduced by the user in a basket that is an integral part of the cover and that is suspended in the interior space of said cover, above the upper face of the tank. This upper face of the tank, which forms a brine collecting surface, is formed by a removable lid.
  • the cover is provided with a top placket for access to the basket so that the user can deposit the load of hygroscopic product in it.
  • This device has the disadvantage that it is composed of several pieces that have a relatively complicated geometry. Another drawback of this device is that it does not have a specific design to prevent the user from coming into contact with the hygroscopic product when handling the load.
  • EP0793060A1 discloses a device similar to the previous one.
  • the replaceable hygroscopic product load itself is constituted by a rigid cell containing the hygroscopic product, which is placed in a basket similar to that of the previous document.
  • the deposit is not closed superiorly.
  • This device also has the disadvantage that it is composed of several pieces that have a relatively complicated geometry.
  • the invention aims to provide a portable dehumidifier device of the type indicated at the beginning, which has a simpler constitution, with fewer parts, and that is easier to handle by the user, while meeting the required safety features of use. to this type of device.
  • a portable dehumidifying device of the type indicated at the beginning, characterized in that the cell containing the hygroscopic product is fixed in a removable way on the upper face of the tank that forms a collecting surface.
  • the device can consist of only two pieces: the tank and the cover, in addition to the load of hygroscopic product.
  • the placement of the load of hygroscopic product in the device is simple: the user removes the cover, places the load of hygroscopic product resting on the upper face of the tank and makes a manual pressure to fix it.
  • the stability of the device in its position of use is particularly good, because the load of hygroscopic product is placed lower and therefore the position of the center of gravity of the device is also lower.
  • the hygroscopic product is impracticably enclosed in the interior space of the cell.
  • the load of hygroscopic product, formed by the cell and the hygroscopic product constitutes a fungible element.
  • the empty cell is discarded and replaced by a new charge.
  • the cell has a lower base provided with the holes for liquid runoff and, when said cell is snapped into the upper face of the tank, said lower base is distanced from said upper face of the tank at least in an area , of said lower base, which comprises said holes for liquid runoff. Thanks to this configuration, the brine produced within the load is evacuated particularly effectively, which increases the performance of the device.
  • the upper face of the reservoir is open in an outlet conduit that ends outside the reservoir, above the upper face of the reservoir, and the cell comprises a fitting means that snap into said outlet conduit and shutter
  • the hygroscopic product load itself constituted by the cell that contains the hygroscopic product, thus performs the function of a sealing part of the outlet duct, so that when the user pressures said hygroscopic product load on the upper face of the tank, at the same time reliably seals the outlet duct of the tank.
  • This configuration offers greater safety than known devices, in which the outlet duct for emptying the tank is arranged in a side wall of the tank and is sealed by a plug that may be poorly closed or even absent due to an oversight of the Username.
  • said fitting means which snap into the outlet duct and seal it, are formed by at least one blind hole in the lower base of the cell, said blind hole being sized to snap in with said outlet duct .

  • the upper face of the tank which closes said tank superiorly, is immovable. That is to say that the deposit is closed so impracticable by its upper face, unlike known devices in which the upper face that closes the tank is constituted by a removable cover. In this way, the safety of the device is significantly reinforced in the event that it accidentally overturns or is turned over, since the danger of a spill due to a cover that has been incorrectly closed by the user is eliminated.

Effect, to remove the cover it is necessary to move it up a considerable distance, at least equal to the height of the tank. In addition, no means of fixing the cover that can attract the attention of a child is shown externally.
