Embodiment Construction

[0026] In the accompanying drawings, a filter device according to a first embodiment of the invention is indicated generally at 1 . The filter device 1 has a pot-like shape, but similarly, the invention may be adapted for devices for preparing infusions such as tea, coffee or the like. The device 1 comprises a receptacle 2 having a handle 3 and closed at the top by a cover 4 . The lid in turn has a spring-biased flap 5 which automatically closes the pouring spout 6 in an openable manner during pouring.

[0027] A container 7 is fitted to the interior of the receptacle 2 and is fixed to the mouth of the receptacle 2 so as to define a first reservoir 8 for collecting the water to be filtered, a discharge duct 10 opening in the bottom 9 of this container 7 . A filter cartridge 11 is removably arranged in conduit 10 . The rest of the receiver 2 defines a second reservoir 12 for collecting filtered water. The above elements are arranged such that water introduced into the first ...

Abstract

A filtering device (1) for filtering water and liquids in general comprises a first reservoir (8) for collecting the water to be filtered, a second reservoir (12) for collecting the filtered water, which reservoir (12) is supplied by falling from the first reservoir (8), a conduit (10) which extends from the first reservoir (8) into the second reservoir, a cartridge type filtering element (11) which is removably received in the conduit (10), a discharge hole (22a, 31) for the filtered water that is positioned between the conduit (10) and the second reservoir (12), and at least one opening (15) for access to the cartridge provided at an end of the conduit (10) that is distal from the first reservoir (8) in order to promote the removal thereof. The device comprises an at least partial closure which can be removably fitted to the conduit (10) in the region of the opening (15) for access to the cartridge and comprises a flow adjuster which is associated with the conduit (10) in order to adjust the flow of water flowing from the first reservoir (8) to the second reservoir (12) through the discharge hole (22a, 31).

Description

technical field [0001] The invention relates to a filter device for filtering water and liquids in general. Background technique [0002] Such devices are known and widely used in the market due to their ability to provide domestic level drinking water with improved characteristics compared to tap water, i.e. chemical properties (salinity, hardness, etc.) and organoleptic properties. characteristic. [0003] A typical example of such a device is described in WO9613318 by the same applicant. The filter unit disclosed herein is of the type comprising a gravity filter tank wherein water introduced into the upper reservoir flows slowly through a filter cartridge containing a filter element with activated carbon and ion exchange Lower the reservoir. [0004] The filtering effect of a filter element depends on a number of factors, of which the contact time between the filter device and the water to be filtered is of great importance. Gravity causes the water to enter the filte...
