The technical field to which the invention relates

The present invention relates to filters, to filter water, for example for filtering tap water to remove various contaminants. More specifically, the invention relates to a water filter with the water flow by gravity, providing filtration, thereby cleaning the water. The filter is intended for use, in particular but not exclusively, in home appliance of water filtration, such as a filter pitcher.

The level of technology

Ordinary water filters with water supply by gravity is presented in the form of cartridges filled with a mixture of granules of activated carbon and ion exchange resin with the consistency of sand or coffee grounds. Filter media removes sediment, bad taste, such as chlorine taste, hardness and other contaminants such as metal ions and pesticides. In General, ion-exchange resin reduces the hardness of water is caused by calcium ions and/or magnesium, while the granules of activated carbon reduces taste and/or smell of chlorine.

Conventional cartridge water filter has an elongated cylindrical profile, deep enough so that the pollutants can be absorbed by the filter medium for the time required by water to flow through the cartridge �of elytra. As the water flows through a filter medium she chooses the path of least resistance and pave their channels through the cartridge filter. However, educated thus the channels cause any pollution in the water that you want to catch, can seep through the filter cartridge together with the treated or purified water, as the water that flows through the channels, not in contact with the filter medium sufficient time, an effective treatment. Another disadvantage inherent in this type of filter cartridges is low filtration velocity. Another disadvantage is that small particles of coal from a mixture of granules of activated charcoal and ion exchange resins can, along with the filtered water to exit through the outlet of the cartridge filter.

In document EP 2277832 A1 describes a filter pitcher that can be used with various types of cartridges. A filter pitcher includes receiving funnel, which can take cartridges having different sizes and/or shapes. Charging hopper includes a removable insert, which reduces the effective area of the holes on the base in the admissions funnel, so that the receiving funnel, you can attach the cartridges in various sizes.

In document WO 2004/052789 A2 describes the cartridge Autonomous devices for filtered�I water such as a carafe or water jug. The cartridge contains a conventional filter medium consisting of granules of ion exchange and activated carbon. However, to minimize the channels in the filter medium and, thereby, to improve the filtration, the cartridge is arranged in the first and second passages in which the flow passes through a filter medium and which are directed in opposite directions.

Despite the fact that the disadvantage associated with the occurrence of channels in the filter media may have been minimized, but the decision in accordance with W0 2004/052789 A2 still has a low rate of filtration. Moreover, we have proposed a rather complex filter, which probably leads to a higher cost of cartridge.

Accordingly, as can be understood from the foregoing, there is a need for improvement in the field of water filters for home use.

Disclosure of the invention

The object of the present invention is to reduce at least some of the shortcomings inherent in the filter cartridge at the current level of technology.

An additional object of the present invention is to propose a filter for filtering water that produces filtered and purified water for a short time, i.e. to propose a filter for water with high speed�Yu filtering.

Another object of the present invention is to provide a device for the filtration of water containing a filter that allows to increase the ratio between the amount of filtered water and the total volume of the device, i.e., filter pitcher.

At least one of the above task is solved by means of the filter for use in a device for filtering water includes a housing having an inlet for receiving water to be filtered and an outlet for the issuance of filtered water. Between the input and output filter contains water environment. Filtering water environment contains the ion-exchange resin layer and the material layer is filled with activated carbon, and these layers are made as two separate layers, arranged in the housing.

When performing ion-exchange resin layer and a layer of material which is filled with activated carbon, in the form of two separate and distinct layers in the filter media, you can get a thin but effective filter. The relatively thin configuration of the filter, obtained by using two separate layers with a variety of filter media, allows to obtain a filter with a high rate of filtration.

Another advantage relating to a relatively thin configuration of the filter medium, is that now you can develop a filter elusive generally flat profile compared to the cartridges of the existing prior art, having an elongated cylindrical profile. In General, a flat profile filter leads to a funnel into which you insert the filter can be minimized, which, in turn, leads to an increase in the ratio between the amount of filtered water and the total volume of the device, i.e., filter pitcher.

The outcome has been determined, at least one of the tasks mentioned above.

In accordance with a variant implementation, the ion-exchange resin layer located over the layer of material, filled with activated charcoal. Moreover, under the layer of material, filled with activated coal, is a layer of nonwoven material.

At the initial stage of use of the filter, for example, when the filter is new, the first portion of the water passing through the ion exchange layer will be a drop in the pH of the filtered water. Therefore, in some cartridges at the current level of technology we recommend that the first few liters of water, filtered through a new cartridge, poured until then, until the pH is stabilized, and the cartridge is not soaked with water. In the present invention the material is filled with activated carbon, is located below, i.e., layer after ion-exchange resin. The material is filled with activated charcoal, by its nature alkalizes the filtered water. When you use a new fil�RA pH slightly decreases with the passage of the ion exchange layer, but then, after passing through a layer of material which is filled with activated carbon, again will rise to acceptable levels. Accordingly, at any time you can drink water filtered by the filter as described in this document variant implementation.

In accordance with another variant implementation, the filter housing contains a lid having at least one inlet, which forms the entrance of the housing. Moreover, on the cover surface is made of at least two sections, which are arranged with a slope to the outer peripheral portion of the cover.

The slope of the surface cover are stepped to the peripheral portion of the lid. Thus, water flows over the top and spread evenly. Improved distribution of water on the lid provides a good distribution of water through filter medium located under the cover. This, in turn, leads to the fact that the entire filter medium located under the lid, is used in its entirety.

In accordance with a variant implementation of the cap comprises a first portion in elevation view, located in the center of the lid, and this elevation has an inclined edge arranged to distribute water to the peripheral portion of the lid. On the downhill edge of the elevation on the lid made several inlets. Also cover contains� the second phase in the form of intermediate segment, surrounding the dais, and at this intermediate zone is provided by several inlets.

Thus, the water that should be filtered, can seep through the holes in the cover surface as the water passes to the peripheral portion of the cover of stepped inclined surface of the cover. With continuous distribution of water across the surface of the cover reduces the risk of formation of channels in the layer ion-exchange resins.

In accordance with a variant implementation, the filter housing contains a bottom in which is provided with holes forming an outlet from the housing. Moreover, the casing inlet is located above the outlet of the housing, so that the water that should be filtered, can pass through the filter medium under the action of gravity.

In another aspect, at least one of the aforementioned objectives is achieved by the device for filtering water containing the filter, for example, in accordance with the above variants of implementation. Device for filtering water includes a container adapted to hold filtered water, receiving funnel, adapted to set in a container, and to prevent unfiltered water. The filter is adapted to set in the admissions funnel for filtering water supplied � receiving funnel. The filter forms the output of the receiving funnel, through which the filtered water reaches the container, the filter forms a bottom of the receiving funnel so that the filtration water is going across the lower area of the admissions funnel.

Generally flat and elongated shape of the filter constituting the bottom of the admissions funnel, makes it possible to provide a device for the filtering of water with high ratio of filtered water to the total volume of the device for filtering water in comparison with other known devices. Accordingly, the charging hopper may be so arranged as to occupy less space in the container in comparison with filters-jugs existing level of technology. Moreover, a large front area of water contact with the filter also favors the increase in the rate of filtration.

In accordance with a variant implementation, the lid and the bottom of the filter essentially have the same area and in the reception area of the bottom of the funnel. Thus, the area provided by inlet holes, essentially equal to the area provided by the outlets. The constructive characteristic of the reception filter and the funnel facilitates the exit of the filter, which, thus, helps to improve, i.e. increase in the speed of filtration.

In accordance with a variant implementation, the device filter�Oia water includes cover, equipped with a damper that is arranged so as to give the water a chance to get into the receiving hopper through the hole in the lid. Moreover, the valve elastically installed to cover the hole. Moreover, the flap can be swung down from the hole in the receiving funnel so that between the cover and the flap angle is formed up to about 25°.

When the input water stream strikes the flap, it is deflected down into the hole in the lid to allow water to get into the receiving funnel. Thus, the flow of water against the flap, scatters and slows down. Multiple input stream water minimizes the risk of channels in the filter medium under the filter cover.

Further features and advantages of the present invention will become apparent upon reviewing the appended claims and the following description. Specialists in the field of technology it is clear that without deviating from the scope of the present invention defined by the appended claims, various features of the present invention can be combined to embodiments other than those described below.
