Definitions

  • the invention relates to a fresh water storage container for a device for the individual, metered delivery of several pumpable active substances from each storage container into a common working container and for mixing the conveyed active substances in a collecting channel with a working medium, which can be controlled via a controllable fresh water connection line the fresh water storage container has been guided and is removed from an intake line connected to this container, the active substances in particular being detergent substances, the working medium water and the working container being the detergent solution container of a washing machine.
  • Such a storage container is known from DE-PS 32 37 785. It can be filled by a bypass of the fresh water connection line and has a ventilation valve that blocks the passage of water so that the reservoir can be filled completely without overflowing. Its volume is such that the amount of fresh water stored therein is sufficient to completely flush the active ingredients of all the individual doses required for a washing process into the working container.
  • the water-blocking ventilation valve is reasonably expensive and also prone to failure. DVGW requirements for back suction safety have not been observed at all.
  • the invention has for its object to provide a fresh water reservoir of the type mentioned, which is cheap and reliable and also meets the high requirements of the DVGW in terms of safety against suction.
  • this object is achieved in that the closed fresh water storage container is arranged above the working container, that the controllable fresh water connecting line opens into the fresh water storage container at the highest point, that the suction line is connected to the bottom of the fresh water storage container and that a downwardly open mouth of an overflow line led into the working tank via a free air gap is arranged so far below the mouth of the fresh water connection line that the space in the fresh water storage tank above the mouth of the overflow line is so large that the volume of the overflow line can only fill up to a maximum of 20 mm below the mouth of the fresh water connection line.
  • such a storage container can be filled by a controllable fresh water connection line in such a way that this connection line is controlled permeably for a predetermined time, which is certainly sufficient to fill the storage container at a given flow rate.
  • Too much fresh water poured into the tank is pressed into the work tank, which is to be filled with water anyway, via the overflow line.
  • a reservoir filled in this way can still not release its contents through the fresh water connection line if a vacuum would be created in the fresh water supply network when the valve of the connection line is open. Then the water volume located in the overflow line would pull into the storage tank, the overflow line would then suck in air and the water level in the storage tank would only rise up to a height of 20 mm below the mouth of the fresh water connection line. With further suction through the connecting line, only air sucked in via the overflow line would then be taken up.
  • the storage container according to the invention can advantageously be further developed in that the overflow line is guided over a detergent dispenser.
  • the reservoir can be so close to the detergent dispenser that the volume the overflow line is very small because of its brevity. This has an advantageous effect on the design of the storage container in that the "dead" space between the mouths of the fresh water connection line and the overflow line can be kept very small.
  • the active substance containers 1 to 5 are connected via lines 6 to 10 to the individually controllable valves 13 to 17.
  • a further storage container 40 for water is provided, which is connected to the valve 12 via the working medium suction line 11.
  • the fresh water supply line 402 which is connected to the fresh water connection line 406 via the solenoid valve 403, opens into this storage container 40.
  • the valves 12 to 17 each open into the collecting channel 19, the outlet 20 of which opens into the working container 35 via a pump 21 and a line 22.
  • the valve block in which all the valves are arranged, also contains a control device for the valves, which is not shown here.
  • the collecting channel 19 is designed in such a way that a good flushing is ensured and that possibly small amounts of active substance that are running in from the valves 13 to 17 cannot mix with one another during the down times of the pump 21. This can be achieved in a stretched collection channel 19 by an inserted screw, which divides the collection channel 19 into individual chambers, but which are connected in series so that the fresh water in the direction of the exit with the valve 12 open and the pump 21 running 20 flows through the collecting channel 19 at a high flow rate.
  • the overflow line 401 is provided, the downwardly open mouth of which extends so far into the reservoir 40 that the space in the reservoir 40 above this mouth is so much larger that the volume of the overflow line is only up to a maximum of 20 mm below the mouth of the fresh water Connection line 402 can fill up.
  • the dimension 407 is so large that the space of the storage container above the mouth of the overflow line 401 is so large that on the one hand it can absorb the entire contents of the overflow line 401 and then the level of the received in the storage container 40 Liquid is still 20 mm below the mouth of the fresh water connection line 402.
  • the overflow line 401 either opens directly - as shown in FIG. 1 - into the working container 35, this connection being established via a free air gap 405 so that no lye is sucked out of the working container 35 when water is sucked back from the overflow line into the reservoir 40 can.
  • FIG. 2 A particularly advantageous embodiment of a storage container for washing machines, which, in addition to the device shown in FIG. 1, is equipped with a detergent dispenser tray for storing hand-dosed amounts of detergent, is shown in FIG. 2.
  • the detergent dispenser 5 has an opening 50 on the bottom, which is connected to the working container 35 of the washing machine via a hose line (not shown).
  • the detergent dispenser 5, which is not shown in detail, also has water supply lines which are controlled by further solenoid valves 51 and 52, the inputs of which are also connected to the fresh water connection line 406.
  • the overflow line 401 of the fresh water storage container 40 is coupled to a high point of the detergent dispenser. Since this storage container 40 can be arranged in close proximity to the detergent dispenser 5, its overflow line 401 is also very short.
