Adjustable water flow device for shower faucets with automatic flow regulation depending on the pressure

Field of technology

Invent a water-saving device for shower faucets.

Current state of the art

Due to the ever-rising price of water, there are water-saving devices combined with so-called aerators. The goal is to let the tap only have the amount of water that is needed for effective washing. This is mainly used in places where the user does not pay for water and does not have the motivation to wipe with water. These are public buildings, hotels, hospitals, public social facilities, etc. It can of course also be used very well in the home, especially where children or other people who have not acquired economical habits regarding water consumption, or cannot handle the flow of water sensitively enough, are washing themselves. to set. Then, for example, with a lever faucet, they can comfortably release the water at full capacity, however, only the pre-set maximum flow rate will be protected.

The utility model UV 16096 U1 is known as a water-saving device for showers, intended for a standard connecting metal piece with two diameters. The larger upper diameter has an internal thread and the lower part with a smaller diameter is provided with an external thread, on which the shower hose is then mounted. A seat is formed between the parts of the connecting piece, on which the regulator is placed from above, which is a ring with holes on the bottom and is equipped with a limiting ring that ensures its position in the smaller inner diameter of the lower part. Regulation is carried out with the help of O-rings located on the inner diameter of the regulator. The number of O-rings is the only possibility to adjust the flow regulation.

The aim of the invention is to present a device of the above-mentioned type, which, in addition, allows for multi-stage regulation of the flow without disassembling it, only by manipulating the relevant single-pipe mechanism from the bottom of the device.

The essence of the invention

The aforementioned shortcomings are eliminated by the adjustable water flow device for shower faucets with automatic flow control depending on the pressure according to the invention, the essence of which lies in the fact that the mower has a permeable bottom with a central hole in the middle, which is located in a reinforced ring, whereby the central hole is with its lower controller, a setting regulator is installed, which consists of an upper stem, and between the lower controller and the upper stem, a setting element is made in the form of a pair of non-running segments of the setting regulator, which are arranged against each other. Each of them takes up the area of a circular cross-section with a size of 90°, whereby the upper surfaces of the non-running segments of the setting regulator are shaped in such a way that at the beginning of their risers they have a starting edge and at the end of the risers they have a lifting end edge, whereby both starting edges and end edges are on the segments are mirrored to each other and the lower surfaces of the non-running segments of the setting regulator are flat. Two non-running segments of the dividing element rest on the non-running segments of the setting regulator from above, made on the lower part of the collar of the dividing element and are arranged against each other, whereby each of them occupies the area of a circular cross-section with a size of up to 180°, whereby the non-running segments of the dividing element are shaped in such a way that at the beginning of their riser they have a starting edge and at the end of the riser they have a lifting end edge. The two starting edges and the ending edges are arranged mirror-image to each other on the non-running segments of the dividing element, whereby the upper disc is equipped with gearing with a lower cut gear, whereby two opposite long teeth protrude from the circumference of the gearing. The dividing element is inserted through the hole in the support ring, and then through its collar

- 1 CZ 309990 B6 protrudes from the support ring and the collar is arranged in the assembly in the lower part of the collar, whereby an outer groove is made along the length of the externally extended wall of the carrier ring for insertion into two long ribs on the inner circumference of the collar and along the length of the inside of the wall an internal guide groove, for guiding the opposing long teeth on the gearing on the upper disc of the dividing element, through which the internal oblique bearing surface corresponds in shape and size to the lower bevel gear.

An example of the implementation of the invention

Giant. 1 is a view of the assembled device according to the invention stored in the armature for connecting the shower. The armature is the aforementioned standard connecting metal piece 1, which has two outer and inner diameters. The larger upper diameter 2 has an internal thread 3 and the smaller lower diameter 4 has an external thread 5, on which the shower hose is then mounted. Between the parts of the connecting piece 1, a seat 6 is formed, on which the mower 50 is placed from above. All the parts of the device are then placed in it, i.e. the setting

- 2 CZ 309990 B6 regulator 40, distribution element 30 and upper regulator 20, and the sealing ring 32 fits on this assembly from above.

Fig. 2 shows a view of the individual components that make up the water saving device according to the invention. On the left are schematic sections of individual components and on the right are views of the relevant components from above or below. Individual components will be described below the figure.

Below, Fig. 2 shows the mower 50, into which the rest of the components are inserted, and which is the supporting element of the entire assembly. As can be seen on the far right in the top view, the mower 50 has a permeable bottom 51 with a central opening 52 in the middle. The central opening 52 is located in the reinforced ring 54, on which the lower grooves 55 are arranged at regular intervals and from which the radial zebra 53 extends. In the picture on the far left, it can be seen that the wall is weakened at the top, so between the lower zebra 57 and the upper wall 57', an oblique mounting 56 is formed. The depth of the mowing box 50 is much greater than according to the state of the art, because the length of the lower ribs 57 and the walls 57' is longer, and the oblique mounting 56 is arranged further from the permeable bottom 51. The length of the ribs 57 is longer because that the adjustment regulator 40 is placed in the central opening 52. This is a completely new element compared to the assembly according to the state of the art, and therefore a place must be prepared for it. In the figure on the right, which is a view of the inside of the clip 50, it can be seen that there are four lower zebras 57 and they are supplemented along the inner perimeter of the clip 50 by two long zebras 58. They are opposite each other and there are always two lower zebras 57 at a regular distance between them The long zebra 58 serves as a guide for the outer grooves 66 made along the length of the outer wall 64 of the support ring 60. This arrangement of the support ring 60 in the cutter 50 is important for the reason that there is another inner guide groove 67 along the length of the inside of the wall 64. in which the toothing 34 of the dividing element 30 is guided by its opposing long teeth 38'. This possibility of a defined setting between the block 50, the support ring 60 and the dividing element 30 is important so that during assembly one does not have to think about the mutual orientation of the dividing element 30 and the setting regulator 40. So that the start-up segments 48 of the setting regulator 40 and 38 of the distribution element 30, which affects the regulation of the flow.

The bearing ring 60 rests on the mentioned inclined mounting 56, which narrows diagonally in its lower part, which creates an outer inclined bearing surface 61, which rests on the inclined mounting 56. The inside is then an internal inclined bearing surface 62. It rests on it with its teeth 34 respectively, the lower diagonal 34' the upper disk 33 of the dividing element 30. The wall 64 above the diagonal abutting surfaces 61 and 62 is also longer. This is because the setting regulator 40 enables the dividing element 30 to be raised by at least 2.5 mm, and thus the wall 64 must be longer by this dimension. On the left is a view of the support ring 60 from above.

Through the opening in the support ring 60, the dividing element 30 passes through, which then protrudes from the bearing ring 60 with its cylindrical collar 31, and as can be seen in the illustration on the right in the top view, the dividing element 30 on the upper disk 33 is equipped with a gear 34 with a lower bevel gear 34', through which the collar 31 is then arranged in the assembly in the lower part of the cutter 50. The toothing 34 differs from the state of the art in having the lower teeth 34', because it is another element regarding the regulation of the water flow. In the basic position, the gear 34 is supported by its lower bevel gear 34' on the internal inclined landing surface 62. When the dividing element 30 rises, the gap between the bevel gear 34', the gear 34 and the internal bevel landing surface 62 increases. This will become apparent in connection with Figs. 11 and 12.

Above the support ring 60 sits the upper regulator 20, which has a central hole 19 and is equipped with a boundary ring 18 around the perimeter to ensure its position in the support ring 60.

Inner rings 59 are arranged on the upper walls 57' of the box 50, and a ring 65 is arranged on the outside of the wall 64 below. When the support ring 60 is pushed into the box 50, the ring 65 is pushed through the inner rings 59, and thus the support ring 60 is secured against being pushed out of the mower 50 in the upward direction due to the water pressure.

Fig. 3 shows the distribution element 30 according to the invention. It consists of a collar 31 and an upper disc 33 is arranged on it, which is equipped with teeth 34 on the circumference with a lower gear 34' and in the middle is provided with a depression 35. The collar 31 is provided with a central hole 39 on the lower cell 36.

In Fig. 4, which is a view of the lower cell 36 of the collar 31, it can be seen that the lower cell 36 is provided with two non-running segments 38 of the dividing element 30, which are arranged against each other and each of them occupies an area of up to 180°, so covering an area of up to 360° from the total area of the lower cell 36 collar 31 when viewed from below. The run-up segments 38 of the dividing element 30 are shaped so that at the beginning of their climb they have a starting edge 36' and at the end of the climb they have a lifting end edge 36''. This will be explained with reference to Fig. 9. The central opening 39 can also be seen. The development of the surfaces of the non-running segment 38 of the dividing element 30 is schematically indicated on the edges of the picture. In the area around the central opening 39, two opposite arc grooves 45 are made, the length of which occupies a circular area slightly longer than 90°. Everything is longer by the thickness of the stop output 37.

This stop output 37 can be seen in Fig. 5 and also that it is arranged on the foot of the upper stem 41. It is a schematic section of the setting regulator 40 according to the invention. It consists of an upper stem 41, a lower control 43 with a control slot 44, and between them there is a setting element in the shape of the non-running segment 48 of the setting regulator 40. They are arranged against each other and each of them occupies an area between 90°, so they cover an area of 180 ° of the total area of 360° of the setting regulator 40, seen from above. The upper surfaces 47 of the non-running segment 48 of the setting regulator 40 are shaped so that at the beginning of their rise they have a starting edge 47' and at the end of the rise they have a lifting end edge 47'', whereby both the start edges 41' and the end edges 47'' are on the non-running segments 48 of the setting regulator 40 arranged mirror-image to each other. This can be seen again in Fig. 9. The lower surfaces 42 of the non-running segments 48 of the setting regulator 40 are flat. The bottom outputs 46 are indicated, which will be commented on in connection with Fig. 7.

Fig. 6 shows a view of the setting regulator 40 from above. Two non-running segments 48 of the setting regulator 40 can be seen, which are arranged against each other and each of them occupies an area between 90°, so they cover an area of 180° from the total imaginary upper surface of 360° of the setting regulator 40 when viewed from above. On the foot of the upper stem 41, stop protrusions 37 are made symmetrically opposite each other. These can then move in the arc grooves 45 when the setting regulator 40 is turned. They serve to prevent it from overturning during the turning movement of the setting regulator 40 after it has turned by 90°. The mentioned arc grooves 45 are therefore a little longer, just about the thickness of the stop outlet 37, i.e. to allow for a full 90° rotation, and at the same time in the arc groove 45, there was also room for the turning to rest the stop outlet 37 on the end of the arc groove 45. The same as the stop the stop output 37 is used to stop the rotation of the setting regulator 40 when returning to the basic position. The development of surfaces 42, 47 of non-running segments 38, 48 is again schematically indicated on the edges of the figure.

Fig. 7 shows a view of the setting regulator 40 from below. Two non-running segments 48 of the setting regulator 40 can be seen, which are arranged against each other and each of them occupies an area of approximately 90°, so they cover an area of 180° from the total imaginary lower surface of 360° of the setting regulator 40 when viewed from below. The straight lower surface 42 of the non-running segment 48 of the setting regulator 40 is provided with lower protrusions 46, which have the shape of a triangle in cross-section. On the lower surface 42 of the non-running segment 48 of the setting regulator 40, the lower outputs 46 are regularly distributed, and there are five of them on each non-running segment 48 of the setting regulator 40. These fit into the lower slots 55 on the reinforced ring at the bottom of the box 50. The importance of the interaction of the outputs 46 and the slots 55 will be discussed below. When marginal output 46 is labeled min. seated in the marginal lower groove 55, then the flow will be the smallest and may have four more stages to reach the highest flow, when the same exit 46 will be seated in the end groove 55. In a schematic partial section, it is indicated how the lower exits 46 and the lower grooves 55 shape compatible. Cooperation of the lower grooves 55 and lower

- 4 CZ 309990 B6 outputs 46 ensures that the setting regulator 40 does not turn spontaneously and thus does not spontaneously change the flow due to water pressure. In order for the lower grooves 55 and the lower outlets 46 to be mutually engaged, the depression 35 on the upper disc 33 is used, because a burst of water is pushed into it, and the adjusting regulator 40 is pressed into the cup 50. The regulated change in flow is achieved by mechanically turning the lower control 43 at stopping the water, because at that moment the regulator 40 can be easily lifted and turned to another required position.

In Fig. 8, there is a schematic fez assembly of the cutting element 50, the dividing element 30 and the setting regulator 40. It can be seen how the upper stem 41 fits into the center hole 39 on the lower part of the collar 31 and the run-up segments 38 of the dividing element 30 on the lower part of the collar 31 abut against the run-up segments 48 of the setting regulator 40. And it can be seen how the setting regulator 40 is seated on the reinforced ring 54 of the block 50 with its lower surface.

As indicated in the assembly of the setting regulator 40 stored in the block 50 and the distribution element 30 arranged above it, the setting regulator 40 is rotatably seated in the block 50 in its central opening 52, around which the center reinforced ring 54 is arranged with its lower controller 43. As the lower arrow indicates, the setting regulator 40 only rotates, in both directions. And as the arrow above indicates, the dividing element 30 again moves up and down, according to the direction of rotation of the setting regulator 40.

Fig. 9 explains the mutual interaction of the rise of the run-up segments 38 of the distribution element 30 on the lower cell of the collar 31 of the distribution element 30 and the rise of the run-up segments 48 of the setting regulator 40. In the picture, the risers are spread out in a plane, but in reality they are curved like the risers of a screw thread section. The picture on the left shows the beginning of the joint climb. After assembly in the basic position, the ramps of the start-up segments 38 of the distribution element 30 at the collar 31 and the ramps of the start-up segments 48 of the setting regulator 40 are placed mutually in such a way that the start-up segments 48 of the setting regulator 40 slide only on the upper half of the start-up segments 38 of the distribution element 30. the segments 48 of the setting regulator 40 and the start-up segments 38 of the dividing element 30 are mutually arranged as follows: The start-up segments 48 of the setting regulator 40 occupy in the initial position half of the length of the path of rise of the start-up segments 38 of the dividing element 30 at the collar 31. The stroke takes place on the second half of the path of the rise of the start-ups segments 38, 48, viz. picture on the right - and the stroke size is marked as x. The development of the run-up surfaces is schematically indicated on the edges of Fig. 4 and 6.

As soon as the bottom controller 43 starts to rotate, the run-up segments 48 of the setting regulator 40 start moving along the second half of the length of the path of the run-up segments 38 of the dividing element 30 at the collar 31 according to the arrow. With this movement, I raise the starting segments 38 of the dividing element 30 the entire collar 31 until the starting edges 47' come under the end edges 36'' of the starting segments 38 of the dividing element 30 at the collar 31, which does not rotate, only moves up. After the end of the climb stroke in the range of 90°, the end edge 36'' of the starting segment 38 of the dividing element at the collar 31 reaches above the starting edges 47' of the starting segment 48 of the setting regulator 40. Thanks to the rotation of the starting segments 48 of the setting regulator 40, the starting segments 38 of the dividing element are raised 30 by distance x. When turning, I raise the stop protrusions 37 at the same time. The height of the stop protrusions 37 must therefore be slightly higher than the distance x of the stroke, so that even in the final phase of rotation, the adjustment regulator 40 can rest firmly on the end of the arc groove 45 and thus protect 40.

In Fig. 10, all the components from Fig. 2 are in a compact assembly and in the cavity of the cube 50 in a state of minimum flow. The entire mower 50 is then placed in the connecting piece 1, which is screwed onto the faucet outlet. As indicated by the hatched route, the water flows through the central hole 19 in the upper regulator 20. Next, the water falls on the upper disk 33 in the depression 35, where it reaches a wave, and from there, the stream thus waved flows between the teeth of the gear 34 and around the lower six-wheel 34' and around the inner oblique seating

- 5 CZ 309990 B6 surface 62 of the support ring 60 and from there it falls on the collar 31, where the current acquires a tubular shape. The current created in this way passes through the permeable bottom 51 of the cutter 50, and flows out through the gaps between the radial zebras 53. There is only a small gap between the bevel gear 34' and the internal bevel bearing surface 62 of the support ring 60. It is good to see here how the stop output 37 is guided in the arc groove 45.

In Fig. 11, all the components from Fig. 2 are in a compact assembly and in the cavity of the cube 50, but at maximum flow. The setting regulator 40 is turned by 90° and the raceways on the upper surfaces of the running segments 48 of the setting regulator 40 maximally raise the pitches of the running segments 38 of the dividing element 30 at the collar 31. Thus, the collar 31 and the entire dividing element 30 are raised by a distance of x. The central opening 39 is also raised by the same distance x, but above all the upper disk 33 with the teeth 34 and the bevel gear 34', so that a gap z is created between the lower bevel gear 34' and the internal inclined bearing surface 62 of the support ring 60. This enables a significantly greater flow water.

If we return to Fig. 7, there are five lower protrusions 46 on the lower surface 42 of the segment 48 of the setting regulator 40, spread regularly in five positions within the quarter circle. In Fig. 2, on the reinforced ring 54, you can see the lower slots 55 arranged at regular intervals, and the mentioned lower exits 46 are located in these. There are sixteen lower slots 55 and ten lower exits 46.

Fig. 10 shows the basic situation when all ten lower outlets 46 are stored in their ten lower starting grooves 55. This is the smallest flow rate. After turning the adjusting regulator 40 by 90°, all ten lower outlets 46 are stored in their ten lower end slots 55, and in the meantime it is possible to make four turns of the adjusting regulator 40, when the adjusting regulator 40 moves by one lower outlet 46 and thereby regulates the flow. Each rotation means a slight lifting of the collar 31 of the distribution element 30. With four rotations, the maximum lift x of the distribution element 30 occurs, i.e. the maximum flow. To prevent overturning, the stop protrusions 37 reach the end of the arched groove 45.

With the described device, it is possible to regulate the flow in several stages, in the presented case in five, in a very simple way, without having to remove the entire device from the faucet socket. It is of course possible to have coarser regulation, e.g. in three or even two stages with the corresponding number of slots and outputs. Just turn the setting regulator 40.

The final inventive element is that the permeable bottom 51 is made of a flexible material, and when high water pressure hits the upper disc 33, the entire dividing element 30 pushes down against the permeable bottom 51 and causes it to bulge as indicated. At that moment, the dimension z also shrinks and the flow rate decreases. This is an effective measure especially in the case of multi-storey buildings, eg hotels, when the water pressure decreases towards the higher floors. In the event that there is a consumer peak, for example in the morning, when many guests are showering and flushing, there would be insufficient pressure in the upper floors without this throttling. And thanks to the throttles, the water pressure is maintained at the normal level even on the higher floors.

In the event that the water pressure from above would be too great and would completely press the dividing element 30 onto the internal inclined bearing surface 62, the internal inclined bearing surface 62 is provided with ridges 8 around its circumference, which ensure that at least water will be able to flow between them in sufficient quantity. The notches 8 can be seen in Fig. 2 and 11.

Multi-stage regulation can also be achieved so that the device responds to changes in water pressure in the pipe. This happens in situations where there is an immediate increase in consumption, i.e. when multiple consumption points in the building are activated at one time or even in the case of a sudden drop in pressure in the supply pipe. At that moment, the moving part, i.e. the dividing element 30, reacts by closing or opening the slot at the lower cut-off 34' depending on the water pressure, thereby ensuring the same amount of water at the outlet even when the water pressure fluctuates. This rise or fall

- 6 CZ 309990 B6 of the dividing element 30 is transferred to the intermediate piece formed by the setting regulator 40, and this rests on the permeable bottom 51 of the basket 50 made of flexible material.

Industrial usability

The device according to the invention can be used wherever it is necessary to wipe with water and, in particular, to gently regulate the necessary flow. It can also be usefully installed, for example, in high-rise buildings where the water pressure is different on the lower floors and on the upper floors. Thanks to the flexible bottom, there is no need to set a different flow on each floor 10, because thanks to the above-mentioned shortening, all devices can be set to the same flow. It is therefore a self-regulating effect.

Faucets or lever taps can be conveniently turned on fully when using the device, with only a pre-set maximum flow rate. The device prevents the formation of limescale and achieves 15 significant water and energy savings for the production of hot water.
