Description

The present application is a U.S. National Phase Application under 35 U.S.C. § 371 of PCT/ES2016/070820 filed Nov. 17, 2016 which is incorporated by reference herein in its entirety.

TECHNICAL FIELD OF THE INVENTION

This invention lies within the field of dehumidifiers, in particular rechargeable dehumidifiers, comprising a first cavity in which a desiccant agent is provided and a second cavity arranged below the first cavity in order to collect the water absorbed by the desiccant agent.

BACKGROUND OF THE INVENTION

Dehumidifiers are devices that allow absorbing ambient humidity. There are several types: electric, in which a pump extracts the ambient humidity and condenses it into a container; rechargeable, which do not require an electric connection but require a desiccant agent that must be replaced once it becomes saturated, i.e. recharging in order to continue operating.

Rechargeable dehumidifiers are known such as those that the applicant themselves have disclosed in the application for utility model with publication number ES1039679 and the PCT Patent with publication number WO2016166384 in which the dehumidifiers comprise a first cavity wherein a desiccant agent is provided and a second cavity with a transparent portion, said second cavity being arranged below the first cavity in order to collect the water absorbed by the desiccant agent; the mouths of both cavities are facing one another such that they are connected inside so that the water from the first cavity falls by gravity and is collected in the second cavity.

This arrangement of the cavities implies that the configurations of the device must anchor these to one another in a fixed manner in order to configure a stable and relatively sealed assembly so as to prevent spills between the cavities and outside of these.

Therefore, it is common for the bodies forming the cavities, usually called casings for the lower cavity and lid for the upper cavity, have relatively complex configurations, such as lips, burrs for anchoring by clipping, etc. All these configurations involve discontinuities on the surfaces that affect the outward appearance of the dehumidifier, its aesthetics, and complicate its manufacture since they involve dies in moulds or machining or the joining of several parts.

DESCRIPTION OF THE INVENTION

The present invention is established and characterised in the independent claims, while the dependent claims describe additional characteristics thereof.

The subject matter of the invention is a rechargeable dehumidifier that includes inside it the components it consists of, with the possibility that none of these project outward, such that it has an outward appearance without projections, as well as being simple to manufacture. The technical problem to be solved is to configure the components and their arrangement with respect to one another in order to achieve the aforementioned subject matter.

In view of the above, this invention relates to a rechargeable dehumidifier, in the sense that it includes a desiccant agent of any known kind, such as a tablet, a bag with granules, etc.

The dehumidifier comprises a casing with at least one first opening that is open on the top, as a basin, which configures a first internal cavity, a first lid arranged on the casing acts as a closing or covering element for the casing.

The dehumidifier is characterised in that within the first cavity is arranged a vessel which in turn comprises a body that is open at the top which configures a second cavity, a second lid is provided on top of the body and said second lid has at least one second opening that serves as a passage to the second cavity; on the second lid there may be provided a desiccant agent such that the water absorbed from it is collected in the body when it falls by gravity.

One advantage is that by arranging the components inside the outside can be designed as uncluttered as desired, which achieves a minimalist outside appearance, according to current aesthetic tastes.

Another advantage derived from the previous one is that the configuration both of the casing and its lid can be as simple as desired, with straight and smooth walls.

Another advantage derived from the previous one is that the materials of the casing can be difficult to shape into complicated surfaces, and since the configuration can be simple this makes it simple to manufacture even with such materials, as would be the case if the casing were made in a ceramic material.

Other advantages related to features mentioned in the dependent claims are mentioned in the detailed description below.

DETAILED DESCRIPTION OF THE INVENTION

We shall now describe a first and a second embodiment of the invention based on the figures.

FIGS. 1 to 3 show a rechargeable dehumidifier comprising a casing (1) with at least one first opening (1.1), in the embodiment shown these are multiple circular openings although it could also be a single large opening or several openings with other shapes different to that shown, and open on the top; a first lid (2) is arranged on the casing (1). FIG. 3 shows details of the internal components of the casing (1), such that they configure a first internal cavity (1.2), wherein a container (3) is provided that in turn comprises a body (3.1) that is open on the top which configures a second cavity (3.2), a second lid (3.3) is provided on the body (3.1) and has at least a second opening (3.4), which in the embodiment shown are multiple curved slots although it could be a single large slot or several slots with different shapes to the one shown; on the second lid (3.3) may be provided a desiccant agent (S), of any known kind, the one shown being a bag with a desiccant product inside, such that the water absorbed by it is collected in the body (3.1) when it falls by gravity. FIG. 3 shows with a dotted line the level reached by the water collected (W), and a dotted vertical line with an arrow pointing downwards shows as an example how the water passes through a second opening (3.4) to the body (3.1) of the container (3).

FIG. 4 shows the option that a second lid (3.3) is connected to the body (3.1) via a first portion (3.5) that is thinner in order to act as a hinge. This connection shown is an embodiment since it could simply rest on top or be fixed in any other known manner such as glued, welded, with clips, etc. The advantage of this embodiment is that it can be manufactured in a simple manner by injection, especially when made in a plastic material.

FIGS. 3 and 4 show the option that the container (3) has at least one handle (3.6) connected to the body (3.1), which makes it simple to extract, especially when there are at least two handles (3.6) as shown in the figures. In particular, the handle (3.6) is connected to the body (3.1) via a second thinner portion (3.7) that acts as a hinge. Similarly, as mentioned for the second lid (3.3), this connection shown is an embodiment since it could simply be an extension or be fixed in any other known manner, such as glued, welded, etc. The advantage of this embodiment is that it can be manufactured in a simple manner by injection, especially when made in a plastic material.

Another option is for there to be a hook-shaped configuration (3.8) protruding from the handle (3.6), FIGS. 3 and 4, which fits together with a burr (3.9) that projects from the second lid (3.3), FIG. 3.

It is especially advantageous that the second lid (3.3) and each handle (3.6) are connected via the corresponding thinner portions acting as hinges, first (3.5) and second (3.7) respectively, as shown in FIGS. 3 and 4, as well as joining the hook (3.8) that clamps with a burr (3.9). Thus, the full container (3) can be manufactured by injection in a simple manner, especially if it is made in plastic; FIG. 4 shows the part as it would come directly from the injection mould, without the need for slides in the mould, but being unmoulded directly, which makes the manufacture simple and inexpensive. Its assembly is also simple since it is enough to perform a first fold where indicated with the arrow A in FIG. 4 in order to approximate the second lid (3.3) to the body (3.1) and subsequently at a second fold indicated with arrow B approximate each handle (3.6) until each hook (3.8) fits its corresponding burr (3.9).

One option in order to provide a float that indicates the level of water collected is for a body (3.1) in the second cavity (3.2) to have at least one first wall (3.10), FIGS. 3 and 4, in order to configure inside it a housing (3.11), FIG. 4, within which to provide a float (4), FIGS. 1 to 3, 5 and 6, such that it can move vertically within said housing (3.11).

In particular, in a first embodiment, FIGS. 1, 3 and 5, the float (4) comprises a float (4.1) that adapts to the inside of the housing (3.11) in order to move within it, with a first post (4.2) projecting from the float (4.1); additionally, the first lid (2) may have an opening (2.1), where the first post (4.2) faces said opening (2.1) such that it can go through it in its vertical movement. This configuration is an option for the user who prefers to have the indication above the dehumidifier, usually depending on stylistic tastes as well as on its location.

In a second embodiment, FIGS. 2 and 6, there is a second post (4.3) projecting crosswise from the first post (4.2); additionally, the casing (1) has a slot (1.2), the second post (4.3) passes through such slot (1.2) and runs across it in its vertical movement. This configuration is an option for the user who prefers to have the indication on one side of the dehumidifier, usually depending on stylistic tastes as well as on its location.

One advantageous option is providing inside the housing (3.11) and on the bottom thereof a stop (3.12), FIG. 3, to support the float (4) when it lies at its lowest position, thus preventing it from becoming stuck in its housing, which is usually smaller at the bottom.

Another option, which serves to provide structural reinforcement, is for the body (3.1) in the second cavity (3.2) to have at least one second vertical wall (3.13) as a reinforcement, FIGS. 3 and 4. In particular it is advantageous for the second vertical walls (3.13) to be three in number and arranged in a star configuration, each occupying at least half the height of the body (3.1), thus making the reinforcement effective and distributed.

Optionally, the casing (1) is made in ceramic material, with the known advantages of durability to humidity and appearance, the container (3) and the float (4) are made in plastic material, with the known advantages of easy manufacture, such as by injection, for example, and corrosion resistance.
