Description

Field of the invention

The invention relates to an aerator for saving and regulating fluids, in particular water.

BACKGROUND OF THE INVENTION

Saving water for washing is now one of the major social issues. This is currently achieved in three ways. The first is a simple reduction of the water flow through the upstream device, which narrows the flow profile and thereby reduces the final volume of water flowing out of the faucet. Water flow reductions are in most cases small devices that are mounted in front of the arm tap in the direction of the water flow. Alternatively, they can already be included in the shoulder tap. The disadvantage of this solution is the relatively low saving while maintaining the washing comfort and the possibility of fast filling of the containers or reducing the washing comfort with higher water savings and slow filling of the containers.

The second way is to reduce the water flow while maintaining the volume of the liquid by means of a mix with air. Air is sucked into the liquid and mixed due to the underpressure created by the Venturi effect, where air is sucked from the outer periphery of the liquid at the exit point of the narrowed water flow profile into a larger space and then mixed with air. This solution is realized by front air intake. The disadvantage of the solution is that the air-water mixture is gradually built up depending on the water flow and, moreover, there is always a slower filling of the vessels.

For example, the solutions described in WO 2010/116115 A1, US 2007/0158470 A1, EP 2756878 A1, US 6001250B or CZ 306447 are known in the art.

The third way is the controllable reduction of water flow, with or without air, the disadvantage of these solutions is that the flow reduction is always upstream of the nozzle and thus lower flow rates are even more disadvantageous in volume compared to higher flow rates due to the reduction in flow velocity.

SUMMARY OF THE INVENTION

The aerator of the present invention largely eliminates the disadvantages of existing solutions. The aerator according to the invention consists of an external threaded mounting part, an inner part for seating sieves for channeling and connecting the water jet, at least one set of coarser and finer strainer for channeling and connecting the water jet, water distribution part, control part and dirt screen. in the following way.

At least one set of coarser and finer strainer for channeling and connecting the water stream is inserted into the inner part for the sieves to direct and connect the water stream, so that the last sieve reaches 4.5 mm below the wider edge of the part and 1.5 mm below part for water distribution. In addition, a water distribution part having 12 water inlet openings made on pitch circles of 6.5, 8.5 and 10.5 mm, with holes of 0.5 to 1 in diameter, is inserted into the inner part for seating the sieves to direct and connect the water stream. , 5 mm. The water distribution part is provided with internal stops around its circumference to adjust the limits of the water flow control. Into this water distribution part is inserted a regulating part which consists of a thin-walled circular element and a part for mechanical rotation of the thin-walled circular element. The thin-walled circular element is provided with shaped openings which partially or completely cover the water inlet openings. The thin-walled circular element is provided with an outer stop on the circumference to adjust the control limits

Water flow. When assembling the aerator, the mechanical rotating part of the thin-walled circular element is passed through the center of the water distribution part, through the center of all fitted sets of coarser and finer strainer for channeling and joining the water flow and that part of it extends beyond the bottom of the inner part for sieving the sieves to direct and connect the water jet and thus allow it to be rotated by the fingers or tool. Finally, a strainer is placed in the inner part for seating the strainers to direct and connect the water jet. The whole set assembled in this way is inserted into the outer part with mounting thread.

The advantage of the solution according to the invention is that it is possible to choose between maximum and minimum flow, thus enabling both high water savings and avoiding time losses when filling the containers by simply turning the control part to a predefined range given by individual quadrants defined by the arc length. two side-by-side internal stops for adjusting the water flow control limits mounted on the circumference of the water distribution part. At a pipeline pressure of 4.25 bar, the quadrant K1 allows the regulation of the water flow in the range of 1.2 to 9 1 / min, the quadrant K2 allows the regulation of the water flow in the range of 2.2 to 9 1 / min; range 3.9 to 9 l / min and quadrant K4 then allows regulation of water flow in the range 5.2 to 9 l / min. The quadrants are selected when assembling the aerator, so that an outer stop located on the periphery of the thin-walled circular element of the control part is inserted between the respective inner stops located around the periphery of the water distribution part. Another advantage is the ability to aerate the water stream at any flow setting, by reducing the number of nozzles and reducing their cross-section.

Combination of the water distribution part, which is provided with 12 water inlet openings made on pitch circles of 6.5, 8.5 and 10.5 mm, with the openings having a size of 0.5 to 1.5 mm and a regulating part which partially or completely overlapping the water inlet openings according to the selected quadrant, a significant reduction in water flow can be achieved up to 0.5 to 1 l / min when turned and set to minimum flow. while maintaining sufficient comfort for washing and personal hygiene while turning and adjusting to maximum flow to significantly increase water flow to values of up to 10 1 / min. Thus, a sufficient flow rate for filling the containers is achieved.

The aerator according to the invention is placed in a battery arm, and a seal is used to seal the joints.

The aerator of the invention can be used with any commercially available hanger battery, thus saving costs.

Six sets of coarser and finer mesh 6 are placed in the inner part 2 for seating and connecting the water jet, so that the last wire 6 reaches 1.5 mm below the water distribution part 3. In addition, a water distribution part 3 is provided in the inner part 2 for seating the sieves 6 for channeling and connecting the water jet, which is provided with 12 water inlet openings 7 provided on pitch circles 6.5, 8.5 and 10.5 mm, the openings 7 being 1. mm. The water distribution part 3 is provided on its circumference with internal stops 8 for adjusting the limits of the water flow control. Into this water distribution part 3 is inserted a regulating part 4, which consists of a thin-walled circular element 5 and a part 11 for rotating the thin-walled circular element 5 mechanically. The thin-walled circular element 5 is provided with shaped holes 9 which partially or completely overlap the water inlet holes water inlet openings 7. The thin-walled circular element 5 is provided on its periphery with an outer stop 10 for adjusting the limits of the water flow control. When assembling the aerator, the mechanical rotation part 11 of the thin-walled ring element 5 is passed through the center of the water distribution part 3, through the center of all the sets of coarser and finer strainer 6 used to guide and connect water. joining the water stream so that a portion thereof extends beyond the bottom of the inner part 2 for seating the strainers 6 to direct and connect the water stream and thus allows it to be gripped between the fingers of the hand. When the control part 4 is fitted, the quadrant K1 is selected so that an outer stop 10 located on the periphery of the thin-walled circular element 5 of the control part 4 is inserted between the respective internal stops 8 located along the circumference of the water distribution part 3. Finally, a strainer 12 is inserted into the inner part 2 for seating the strainers 6 to direct and connect the water jet. The entire set assembled in this way is inserted into the male part 1 with the mounting thread.
