Description

(54) HOUSEHOLD CLEANER DRINKING WATER

one

 The invention relates to the field of household appliances, in particular to the by-: TdBbiM drinking water purifier.

A water purification filter is known, comprising a housing, nozzles for water inlet and outlet, an upper and a lower cover with recesses. Inside the case between the grids there is a charge absorber tlDt

The disadvantage of the filter is the use efficiency, iO of the absorber, due to the uneven distribution of the liquid over the absorber section.

The closest technical solution to the invention is a household drinking water purifier, comprising a housing with inlet and outlet nozzles, a lid and a filter element installed in the housing in the wilted layers of filter material and sorbent separated by perforated diaphragms and C23 disks.

However, this cleaner has a volume of activated carbon and, accordingly, a large weight of the device, as well as a limited volumetric filtration rate and, accordingly, low productivity.

These drawbacks are associated with the uneven density of the sorbent, which is loosely filled into the body with a thick layer.

5 The purpose of the invention is to reduce the weight and increase productivity by increasing the filtration rate and reducing the consumption of the sorbent. The goal is achieved by

About the fact that in a household drinking water purifier containing a housing with inlet and outlet nozzles, a lid and a filtering element installed in the housing in the form of layers of filtering material and a sorbent, the filtering element is made up of closed shells made of thermofixed synthetic threads one inside the other posted

2ti between the shells, the ratio of the diameters of the threads of the outer sheath to the diameter of the inner threads being 1.2 + 10: 1, and the ratio of the weight of the filter material to the weight

25 sorbent is 1.3 x 10: 1.

FIG. 1 shows a water purifier with a non-separable filter element, a longitudinal section; Figure 2 is the same, with a collapsible filter element.

A domestic water purifier consists of a housing 1, a nozzle 2 for introducing water, a fastening element 3, a lid 4, a drainage nozzle 5, a bracket 6 for fastening the filter element 7.

The filtering element 7 consists of an outer casing 8, made of synthetic continuous filaments with a diameter, preferably from 6 µm to 15 µm, arranged randomly and thermally bonded to each other at the intersection points; a layer of activated carbon 9 mark WOW, impregnated with silver, in the amount of 10% of the total load of coal; the inner shell 10, also made of synthetic continuous filaments with a smaller diameter, preferably from 1.5 µm to 5 µm, arranged randomly and thermally bonded to each other at the intersection points. Internal area G (G serves simultaneously for tightly fastening the filter element 7 to the lid 4 of the water purifier.

In the case of a non-separable filter element 7, the outer 8 and inner 10 shells are interconnected by a welded base 11,

When assembling, the water treatment element is screwed onto the threads of the bracket 6. The shape of the inner shell can be adjusted, the amount of filler can be adjusted with the same shape and the geometrical dimensions of the outer shell. Tightness when installing the collapsible filter element 7 is achieved by wrapping the outer casing 8 into the thread of the bracket 6.

The inner shell 10 of the cleaning element 7 has a surface density higher than the surface density of the outer shell 8, its thickness is much less. The surface density determines the hydrodynamic resistance of the element. Its change is achieved by using threads of different diameters and different packing densities. The higher the thread diameter and the lower the packing density, the less superficial the density.

The use of fibrous shells from continuous filaments that are firmly fastened together among themselves ensures long duration of work and high quality of cleaning, since this excludes the possibility of formation of fistulas, especially at elevated rates of movement of the filtered water. The use of the outer shell 8 of threads with a diameter of 6-15 microns provides optimal hydraulic resistance with good cleaning quality.

The use of the inner sheath of filaments with a smaller diameter of 1.5-g5 microns. (which provides greater surface density) provides a more uniform movement of the incoming water g over the entire surface of the outer shell when the water moves from

speed (up to 10 l / min). In addition, the inner shell eliminates the possibility of coal particles entering the filtered water.

- Tests have shown that optimal. ratio of the weight of the filter material to the weight of the sorbent (coal) SOS. is set to 1 ,, only at the bottom

5 the value of the specified ratio is provided by the elimination of tastes and odors in the water with their minimum content / at the upper limit of values, the elimination of tastes is achieved

0 and odors with their maximum content in water with a minimum weight of the filter element.

The invention makes it possible to reduce the weight of activated carbon by about 40 times compared to the known one, it is easy to replace or regenerate the filter element in the assembly, to increase the duration of the cleaner without regeneration to about 12 months, which is twice the operating time of the known water purifier.
