Definitions
- the invention relates to a device for supplying at least one consumer with water, in particular at a dental treatment station, with an inflow line which can be connected to a fresh water supply and which opens into a collecting container via a backflow-preventing free-fall path, and with a further conveying device which directs the water from the collecting container to Promotes consumers.
- Devices of this type are known in various designs, for example from DE-A 29 15 806, EP-A 524 334 or WO-A 94/23139, and contain certain ones - in order to comply with the free fall distance defined by DIN 1988, even under the most unfavorable circumstances Disadvantage. For example, the overflow of the collecting container must flow freely into a drain connected to the sewage network.
- the certainty that a backflow of the water from the collecting container into the fresh water network is excluded must be further increased.
- the inflow line ends in a dome which is formed above the collecting container and whose clear height corresponds at least to the length of the free-fall path.
- the free-fall section is formed within a space that is open at the bottom, but otherwise tightly closed, in which an air bubble remains in the manner of a diving bell even in the event of a complete flood.
- an odor trap for the overflow line of the collecting container can be formed for the first time, in which a siphon filled, for example, with glycerin or the like is provided.
- an additive for example for the production of a disinfectant solution or the like, can be fed directly into the collecting container, which is thereby also designed as a mixing container.
- the additive is supplied via a second inflow line which can be connected to an additive container and which preferably also opens into the dome of the collecting container.
- a space-saving construction results if a metering pump is provided in the second inflow line, the additive being contained in particular in flexible bags or the like, which can be accommodated at any suitable location.
- the metering pump can be driven by the pressure of the fresh water and has a return line for the fresh water, which preferably also opens into the dome of the collecting container, this fresh water also falling through a free fall.
- a device for supplying at least one consumer 10 with water under pressure comprises an inflow line 2 which can be connected to the fresh water supply 1 and flows freely into a collecting container 6 which is provided with the level sensors 18 controlling the water inflow.
- the collecting container 6 has an upper edge 19 serving as an overflow, over which water which flows in if the inflow control fails, flows through an overflow line 15 into an outlet 16 which can be connected to the sewage network, a siphon 17 being built into the overflow line 15 represents an odor trap.
- the siphon 17 is preferably filled with glycerin or the like.
- the connection of the overflow line 15 to the upper edge 19 of the collecting container 6 is simplified in that the collecting container 6 is inserted into an overflow container 9, the annular space between the two containers 6, 9 forming the first part of the overflow line 15.
- a dome 8 is provided above the collecting container 6 and stands up from a cover 7 of the over-container 9.
- the dome 8 has a clear height in which a free-fall section 4 is realized with at least the height prescribed according to DIN 1988, since the mouth of the inflow line 2 of the fresh water is provided in the dome 8.
- an air bubble in the manner of a diving bell which prevents the backflow remains in the dome 8, even if the overflow line 15 is blocked by a fault and the overflow container 9 is completely flooded.
- Water from the collecting container 6 is conveyed via a line 20 and a feed pump 21, which is in particular a multi-chamber diaphragm pump provided with an electrical swash plate drive, into a buffer container 22 which compensates for pressure fluctuations and from which the consumer 10 is supplied with water at essentially the same pressure becomes.
- the buffer tank 22 preferably contains pressure sensors, not shown, by means of which a supply of compressed air into the buffer tank 22 can be controlled for pressure equalization.
- a second inflow line 12 for the additive leads from the container 11 to the dome 8 and contains a metering pump 13, which is also preferably designed as a diaphragm pump and which, depending on the inflow control of the fresh water, conveys a certain amount of the additive into the collecting container 6 with each drive cycle.
- the amount of additive per working cycle of the metering pump preferably remains constant, and the intervals between the working cycles are changed when the concentrations of the solution in the collecting container 6, which simultaneously represents a mixing container, are to be changed.
- the mouth within the dome 8 also creates a free-fall path for the additive, which reliably precludes the backflow of solution.
- the metering pump 13 is operated by the water pressure of the fresh water and is connected to the fresh water supply via a line 3.
- the operating water of the metering pump 13 also reaches the dome 8 via a return line 14, the mouth of the return line 14 being arranged such that this water also falls through the prescribed free fall distance 4 within the dome 8.
- the unequal inflow of fresh water, working water and additional agent into the collecting container 6 ensures that the contents are sufficiently swirled for the mixing of the liquids, so that an essentially constant concentration of the solution is ensured.
- the control of the supply device comprises conventional valves and, depending on the needs of the consumer or consumers 10, which can be measured by the level sensors 18 Fresh water and, depending on the selected concentration of the solution, add additives, and convey the solution from the collecting container 6 to the consumer (s) 10.
- a float-operated level monitoring can also be provided.
