Description

The invention relates to a flush distributor for a sink, with a first channel to be connected to an outlet of the sink and a second and third channels, each to be connected to a toilet bowl, into which the water from the first channel is distributed when flushed.

A flush-stream distributor of this type has become known in the state of the art, for example from DE 27 07 81 A. It divides the water from a line connected to a toilet bowl in such a way that part of the flush-water is fed to a flush-channel of the toilet bowl and another part of the water is fed to a nozzle located in the siphon of the toilet bowl and, when flushed, produces a push effect which causes the water level in the drain to rise, thereby emptying the contents of the siphon. The water coming from the flush-channel of the toilet bowl cleans the flush-channel.

The purpose of the invention is to create a flushing power distributor of the above type which allows at least sufficient flushing with even less water.

The problem is solved in a type-appropriate flush-stream distributor by the first channel distributing water through a nozzle to the other two channels. The flush-stream distributor of the invention allows for an exact distribution of water into the two downstream channels. In particular, it allows for precise adjustment of the pressure in these two channels.

The flush flow distributor according to the invention is particularly suitable for a pressure sink with a pressure tank in which the flush water is stored under pressure. The flush flow distributor according to the invention is particularly suitable for distributing water from such a pressure sink. The water from such a pressure sink can then be fed directly into the line leading to the nozzle in the siphon. The remaining water can then be used to flush the flush edge.

A particularly advantageous formation of the flush-current distributor is obtained if, according to a further development of the invention, the nozzle is a free-flow nozzle. This can be formed in a particularly simple way so that the flush-current distributor serves at the same time as a pipe break. Such a pipe break prevents water from the toilet bowl being sucked into the supply line at a low pressure in the supply line.

The two channels downstream of the nozzle are coaxally arranged, preferably so that the water from the nozzle flows directly into an opening in the inner channel. This inner channel is then preferably connected to the nozzle of the siphon. This allows a relatively high pressure to be built up in this channel leading to the nozzle, which allows the siphon water to accelerate.

The nozzle is designed to have a conical outlet and a secondary channel is designed to enter into this conical outlet, allowing for a particularly fine-tunable distribution.

The water is then fed from the nozzle to a tube with a funnel-shaped opening, preferably formed as a diffuser, which can largely prevent a pressure shock and can also create an even higher pressure by expanding the water in the diffuser.

The invention also relates to a sink with a sink power distributor according to the invention. The sink is preferably a pressure sink with a pressure tank. The combination of this sink with the sink power distributor according to the invention allows for particularly efficient rinsing with little water. In addition, the space requirement is particularly small, so that a sink can be manufactured with a particularly small space requirement.

The invention also relates to a toilet system with a flush power distributor according to the invention.

The nozzle 17 shown in Figure 1 has a nozzle 17 connected to the outlet 45 of the pressure vessel 4 by a connecting vent 20 and preferably in the form of a free-flow nozzle. Nozzle 17 is in the form of a cylindrical tube and has a mainly vertical first channel 21 connecting the connecting vent 20 to an opposite nozzle 22 and the nozzle 22 has a conical surface 23 which extends and expands downwards as shown in Figure 1.

The second channel 24 is separated from the first channel 21 by a conical space 30 and runs vertically and axially parallel to the first channel 21. The tube 28 has an upper opening 26 which is inserted into the nozzle 22 and is located in the area of the conical surface 23 as shown in Figure 4. The opening 26 is externally surrounded by a conical surface 27 which runs essentially parallel to the conical surface 23. The nozzle 17 is moved vertically so that the conical surface 30 is shortened or enlarged.

The tube 29 is connected at a lower end by a seal 32 to the tube 28. The third channel 25 is thus sealed at the lower end of the tube 29 to the outside of the tube 28. However, the upper end of the tube 29 is open to the surrounding atmosphere at a circular ring-shaped opening 31. As can be seen, the tube 29 has a collar-shaped area 47 extending upwards in a funnel shape into which the lower end of the nozzle 17 is inserted.

The flush-stream distributor 2 shown in Figure 2 has a nozzle 18 similar in structure to nozzle 17 which is inserted into a tube 34 with its lower end. The tube 34 has a vertical support 37 with an opening 38 at its upper end. This opening 38 corresponds in its function to the opening 31 and thus connects the interior of the tube 34 to the surrounding atmosphere. The tube 34 is connected to the inner tube 28 at its upper end by a seal 36 tightly to the nozzle 18 and at its lower end by a seal 35.

Figure 3 shows a flush distribution unit 3 which also has a nozzle 19 with a lower nozzle 39 which protrudes into a vent 43 which, as can be seen, is first widened and then narrowed down into a funnel.

The toilet system 44 shown in Figure 4 is mounted in front of a building wall 5 and connected to a fresh water supply line 6 in which a valve 7 is located. After the valve 7 a pressure sink 4 is connected to the supply line 6 in which a predetermined amount of water 8 is stored and above which a pressure chamber 9 with air is located. Such pressure sinks 4 are known in themselves, for example WO 98/39522 is referred to here. The pressure sink 4 has an outlet 45 to which a distributor 1 is connected. This sink 1 is also designed as a raw material dispenser and is designed to prevent thisthat at a low pressure in the pressure sink 4 or supply line 6 water is drawn from a toilet bowl 10 into the pressure sink 4 and supply line 6. The flush flow distributor 1 distributes the water 8 from the pressure sink 4 into at least two water flows, with a first flow of water flowing into a so-called jet line containing a jet nozzle 46 located in or in front of a siphon 13 of the toilet bowl 10. The nozzle 46 is in the toilet 14 with a water filled area below the toilet bowl 10 and the siphon 13 are filled. The second water flow enters a flush channel 11 of the toilet bowl 10 and passes through openings in the directions below the toilet bowl 12 and cleans the inside of the toilet bowl 10.The siphon 13 is known to be connected to a drainage pipe 15 which leads to a disposal line not shown here.

Figure 5 shows a flush flow distributor 52 in which a significant distance is provided between a nozzle 54 of nozzle 55 and an upper opening 56 of a water-taking pipe 57 in which a free jet 51 is formed. The nozzle 57 has a conical surface 58 externally, so that a comparatively sharp edge 71 is formed at the opening 56. Between the nozzle 54 and the opening 56 there are laterally arranged openings 72 leading into a ring-shaped passage 61 which is open to the surrounding atmosphere. In the case of a downward pressure this creates a particularly safe tube-breaker.

Figure 6 shows a flow distributor 53 in which a free stream S2 is also formed between a nozzle 62 and an opening 66 of a tube 67 nozzle. The nozzle 62 is formed by a wall 64 running transversely to the flow direction, which has a central opening 65 and several side openings 63. This wall 64 already causes a distribution of water in nozzle 62 which flows partly through a channel 69 of a tube 68 to the jet nozzle 46 and partly through a tube 70 to the nozzle 11. As can be seen, the nozzle 67 also has a pressure gap on the inside of the nozzle 73 so that a pressure difference is created in the opening 66 which is prevented by a crack. The pressure is increased in the nozzle 68 so that the pressure can be reached by further expansion of the nozzle 68 and the pressure can be increased by creating a pressure difference in the nozzle 69.

The operation of the flush flow distributors 1, 2, 3, 52, 53 is explained below.

A flush is normally initiated by an actuator not shown here, which opens a drain valve located in the pressure sink box 4 and not shown here, which causes pressure water to flow through the outlet 45 into the flush flow distributors 1, 2 and 3 respectively. This, as shown in Figure 3, forms a first water flow 40 in nozzle 19 flowing at a relatively high speed vertically downwards to nozzle 39. In the area of this nozzle 39 this first water flow 40 is divided into a second water flow 41 and a third water flow 42. The second water flow 41 is set by direct flow of the first water flow 40 so that the initial flow direction 49 corresponds to the water flow direction 48 of the first water flow 40 in the nozzle.The third water stream 42 is formed by the remaining water of the first water stream 40 and runs downwards coaxially to the second water stream 41. This third water stream 42 is formed by a lateral direction of the water in the directions of the arrows 50, in contrast to the second water stream 41. The distribution of the first water stream 40 on the water streams 41 and 42 is preferably such that the water volume of the third water stream 42 is much larger and preferably about twice as large as the second water stream 41.The second water stream 41 leads to the jet line 16 and finally to the nozzle 46, while the third water stream 42 leads to the flush channel 11 and is therefore intended to clean the inside of the toilet bowl 10.

The nozzle 19 is preferably vertically adjustable in the directions of the double-arrow 51. This allows the distribution of the two water flows 41 and 42 to be precisely adjusted. If the nozzle 19 is moved down, the third water flow 42 is reduced and the speed of the second water flow 41 is increased. This allows the water outlet at the nozzle 46 to be optimally adjusted. Also, the flushing of the toilet bowl 10 can be optimized with the third water flow 42 and adapted to the toilet bowl 10. This allows an optimal cleaning of the toilet bowl 10 with minimal water consumption.

The first water flow 40 is divided into two water flows 41 and 42 as described above, but it is also possible to divide the water flow 40 into more than two water flows, for example, another water flow could be used to supply a toilet nozzle, not shown here, to bowl 10.

If a fault causes a pressure drop in the pressure sink 4 or in the supply line 6, for example, in the flow distribution system 3 air is sucked in through the vent 43 and enters the nozzle 19 as shown in Figure 3, thus cutting off the flow of water in the nozzle 19 and preventing water from being sucked into the pressure sink or supply line 6 from the toilet bowl 10. In the case of the flow distribution systems 1 and 2, this function is fulfilled by the corresponding openings 31 and 38.
