Device for treating water for household use

Abstract

A device for treating water for household use designed so as to be temporarily coupled to the mouth of a faucet to allow the continuous supply of treated water and the water to be treated being guided radially through the inside thereof. The device is formed by means of coupling a cylindrical receptacle to an upper closing element, where the receptacle supports, on the inside thereof, a paddle blind on which a hollow, cylindrical-shaped membrane is supported, where the membrane accumulates a filter bed therein. The inner wall of the receptacle is provided with ribs that extend longitudinally so as to define channels through which the treated water flows. The upper closing element is provided with grooves for the inflow of water to be treated, on which sealing means are supported for the coupling to the faucet.

(2) FIG. 1 shows an exploded perspective view of the different elements forming the device for treating water of the invention.

(3) FIG. 2 shows a section view of the device of the invention having been duly assembled.

(4) FIG. 3 shows a plan view of the receptacle and the separating element that are part of the device of the invention.

(5) FIG. 4 shows a section view of the elements depicted in the preceding figure, where the inner face of the receptacle can be seen.

(6) FIG. 5 shows a section view of the device of the invention depicted in FIG. 2, in which the path of the water flow therein has been depicted.

PREFERRED EMBODIMENT OF THE INVENTION

(7) As can be seen in FIG. 1, the portable and disposable device for treating water (1) preferably has a cylindrical outer shape and is made up of a receptacle (2), which is open in the upper portion and provided with a hole (3) in the lower area thereof which allows the outflow of the water.

(8) The receptacle (2) houses filtering means (6) made of non-woven fabric, membrane or filter paper therein which is arranged forming a hollow cylinder and the length of which extends completely or partially along the inside of the device.

(9) A paddle blind-type element (4) is supported on the bottom of the receptacle (2) which forces the water to flow radially from the inner part to the outer part of the device. This spade or paddle blind has flanges at the base acting as spacers (5) which allow leaving a space for accumulating treated water before it flows out through the lower hole (3) of the receptacle (2) without experiencing a pressure drop.

(10) As can be seen in FIGS. 1 and 2, in the cavity of the hollow cylinder created by the filtering means (6) there is arranged a pre-filtration bed (14), in the form granules, beads, or any of another type of ion exchange and/or filter bed.

(11) A cover-like upper closing element (7) is placed on the receptacle, said upper closing element being provided with a plurality of grooves (8) through which the water to be treated flows. The upper closing element defines a cavity the inside of which will house the mouth of the faucet when the device of the invention (1) is temporarily coupled to the mentioned faucet. At the base of this cavity, the closing element has grooves (8) with a dimension that does not allow outflow from the pre-filtration bed (14) which is housed in the cavity formed by the filtering means (6).

(12) The upper closing element (7) can be screwed on, press fit or attached by welding with respect to the receptacle when changing the pre-filtration bed (14) or the filtering means (6) is not envisaged.

(13) This upper closing element (7) has a perforated inner base inner by way of grooves (8) for the purpose of enabling the passage of water to be treated into the pre-filtration bed (14).

(14) It can be seen in FIG. 2 that the cavity formed by the filtering means (6) can receive therein a filter bed for performing filtration through a filter bed, said filter bed having a pre-filtration function and preferably being made up of activated carbon (GAC), an electrolytic component KDF, ion exchange resin or any other means for treating water with a graduated grain size distribution.

(15) The upper closing element (7) is provided on its upper border with sealing means that allow the inflow of water and can be coupled to different mouth diameters of running water faucets. These sealing means are preferably made up of an elastomer (9) acting like a diaphragm. The diaphragm (9) preferably has a planar and flexible shape with a hole (10) in the central part thereof and is fixed to the upper closing element (7) using mechanical means (11) in the form of a washer, which is fixed by welding or bonding.

(16) Finally, the device of the invention is provided with a cover (12) for covering the area of the diaphragm and with a stopper (13) for covering the outlet opening for the treated water (3) when the device is not in use, preventing the circulation of air and assuring the sanitary conditions of the device.

(17) As seen in FIG. 2, the upper closing element (7) is equipped on its lower border with a stop (16) in the form of a protuberance projecting at the base and having the purpose of limiting the depth up to which the mouth of the faucet is inserted into the device.

(18) It can be seen in FIGS. 2, 3, and 4 that the receptacle (2) of the device (1) is provided on the inner face thereof with embossments or ribs (15) that extend longitudinally for the purpose of enabling the formation of channels through which the treated water flows after passing through the filtering means (6).

(19) As can be seen in FIG. 5, the filtering means (6) are coupled on the entire periphery of the inner surface of the receptacle (2). The plurality of ribs (15) that the receptacle (2) has enable the formation of treated water collectors (17) in the cavities thereof, allowing the water to flow between the filtering means (6) and the inner surface of the receptacle (2) to the outlet (3).
