Abstract

FIELD: cleaning and decontamination of water. SUBSTANCE: proposed filter has housing with bottom, cover, water supply and discharge branch pipes and at least two filter elements with filtering or sorbing layers arranged inside them. One filter element has hole in its center for passage of liquid to be treated from center to edges; holes in other filter elements are made in edges for passage of water to be cleaned from edge to center; filtering gaskets laid between filter elements increase their filtering capacity in way of water motion; filter elements are provided with guide wall made in form of curve or labyrinth. EFFECT: extended field of application; enhanced efficiency of filtration. 5 dwg

Description

 The invention relates to the field of water purification and disinfection in domestic conditions, used both in individual dwellings (for one family) and for a group consumer.

 A known ion-exchange filter comprising a housing with a bottom, filled with an ion-exchange mass, equipped with nozzles for introducing source water, and for discharging treated water and installed in the lower part of the housing, a switchgear made of two plates placed one above the other (patent 462329 from 04.29.71, publ. 02.28.75).

 The disadvantage of this filter is incomplete cleaning from biological impurities and from unpleasant odors.

 Also known is a filter for water purification, comprising a housing with a bottom, a cover, nozzles for supplying and discharging water and at least two filtering elements with filtering and / or sorbing layers placed in them (certificate on item 7019, cl. In 01 D 24/18, 1998 - prototype).

 The disadvantage of this filter is the lack of effectiveness of water purification, primarily from biological impurities, odors.

 The objective of the invention is to expand the functionality of the filter and increase the efficiency of water purification.

 The problem is solved as follows.

 A household filter comprising a housing with a bottom, a lid, nozzles for supplying and discharging water and at least two filtering elements with filtering and / or sorbing layers housed in them, according to the invention, an opening is made in one element in the center for passage of purified water from the center to the edges, and in another element, the holes are made at the edges to allow the purified water to flow from the edge to the center, while filter elements are located between the elements, the filtering ability of which increases in the direction of movement in s, and in the elements of the guide wall is set as a curve or a labyrinth. This embodiment of the household filter in comparison with the prototype expands its functionality by increasing or decreasing the number of filter elements. At the same time, an increase in the number of elements improves the quality of water purification, but reduces the filter performance. Reducing the number of filter elements affects the purification of water, but increases the performance of the filter.

 The presence of filter pads in the household filter, the filtering ability of which increases in the direction of water movement, improves the quality of water treatment. In addition, the simple arrangement of the filtering elements (one above the other) in the filter, their versatility make it easy to replace them, and the presence of a guide wall in the form of a curve or a maze improves the quality of water treatment.

 A comparative analysis of the proposed solution with the prototype allows you to highlight the features that distinguish the proposed solution from the prototype, which meets the criterion of "novelty."

 The analysis of technical solutions did not reveal among them solutions that match the distinguishing features of the proposed solution, which meets the criterion of "inventive step".

 The invention is illustrated by drawings, where in Fig. 1 is a general view of a household filter, in Fig. 2 is an element with a central hole, in Fig. 3 is an element with holes in the edges, in Fig. 4 is a filter pad with a variable cross-section (with a variable filter ability), in Fig.5 - the guide wall in the form of a curve or a maze.

 The household filter consists of a housing 1 with a bottom 2, a cover 3, water supply pipes 4 and water outlet 5 and a filter part 6 made in the form of at least one pair of elements 7, 8 with filtering 9 and (or) adsorbing 10 in layers. In the elements 7, 8 holes 11, 12 are made, and the holes 11 of the element 7 are made in the center (Fig. 2), and the holes 12 of the element 8 are made at the edges (Fig. 3), and filter elements 13 are located between the elements 7 and 8 , 14 (figure 4), the filtering ability of which increases in the direction of fluid movement. Also, in the elements 7, 8, a guide wall 15 (Fig. 5) is made in the form of a curve or a labyrinth.

 Household filter works as follows.

 Using the water supply pipe 4, the filter is connected to a water tap. The source water through the water supply pipe 4 is supplied to the Central hole 11 of the element 7, flows through this hole and through the filter layer 9 from the center to the edges, through the filter pad 13 with the least filtering ability, where it is removed mainly from mechanical impurities. Next, water enters through the hole 12 of the element 8 into the adsorbent layer 10, passes through it to the center through the filter pad 14 with the greatest filtering ability. Biological water treatment is carried out here.

 Treated water flows out of the housing 1 through a water outlet 5.

 In addition, the guiding wall 15 is made in the elements 7 and 8, due to which the water makes a longer path and its additional cleaning is in progress.

 This embodiment of the household filter expands its functionality and increases the efficiency of water purification.
