Definitions

  • the invention relates to a system for waste water use in the household a wastewater-generating device that has a first pumping device a tank is connected, the tank via a second pumping device connected to the cistern of a toilet and the tank and the Cistern each contain a level switch.
  • the invention further relates to a Wastewater Use Process.
  • the invention has for its object the design effort for a to simplify such plant for the use of waste water and in particular to achieve that with a subsequent installation of the system in existing household systems on the existing devices, especially on the cistern, no or only a few changes required are.
  • the object is achieved in a generic system in that the first pump device together with a third level switching means on Odor trap of the waste water generating device is arranged and that third level switching means with increasing level in the odor trap and full tank a discharge of the excess wastewater into the Odor trap subsequent sewerage causes.
  • the first pump device is thus together with a third level switching means on the odor trap of the waste water Device arranged, and the third level switching means causes increasing Level in the odor trap and full tank a derivative of the excess waste water in the subsequent to the odor trap Sewerage.
  • the odor trap the is practically present in every wastewater generating device, in the sense of a Double use for two purposes. Once serves Odor trap for easy and safe measurement of how big the attack Is waste water. The water level in the Odor trap indicates whether there is no waste water to feed the system is available and fresh water must be fed in if necessary, whether Waste water is available in sufficient quantity for feeding into the plant or whether there is any excess wastewater that goes into the sewage system must be derived.
  • the sewer following the odor trap serves when excess wastewater has to be drained, for draining of the wastewater into the sewage system.
  • the level measurement on the one hand and the On the other hand the excess wastewater is discharged in advantageously directly at the point where the wastewater is generated. This results in a structurally particularly simple solution in which only minimal changes to an existing toilet facility are required. Also an overflow for excess wastewater, as in the prior art either on the tank or on the cistern is not required because in principle no excess wastewater is fed into the plant. The The system therefore does not need any for the discharge of excess wastewater additional channel connection and no tapping of an existing one Sewer connection.
  • the level switch in the odor trap causes one constant level of waste water in the odor trap, so that the perfect function of the odor trap to prevent odors is guaranteed.
  • the second is Pumping device in the lower area of the tank. This will make a complete The tank has been emptied.
  • one is the second Pump device with the cistern connecting pipeline within the Inflow pipe from the cistern to the toilet and thus remains with one Retrofit invisible.
  • the tank contains a third one Pumping device used to clean the system waste water from the tank in the Sense of a so-called backwash in the sewage system. Through this Solution can be cleaned at regular intervals with little effort the system can be effected by backwashing.
  • the third pumping device arranged in the area of the tank in which the Waste water is introduced into the tank by the first pumping device.
  • the tank is a electrical control unit with control inputs and control outputs assigned.
  • This control unit is controlled by a central Control after evaluating all the necessary parameters Function of the entire system in all conceivable operating states guaranteed.
  • the level switching means in the tank is preferably with a float formed an upper and a lower switching element. It will Switching element in an advantageous manner by a limit switch or one-sided float switch formed.
  • the level switch in the cistern can by a limit switch or a one-sided float switch and a solenoid valve may be formed.
  • a process for wastewater use that is variable can also be adapted to the needs of small households.
  • it can also be combined with other known methods for waste water use, for example for the use of collected rainwater.
  • waste water use for example for the use of collected rainwater.
  • they can be installed inexpensively in every household.
  • they are also designed so small that they can be used even in small spaces is usable.
  • a toilet can also be embodiments produce in which, for example, via leads in the Kitchen waste water can be used for flushing the toilet.
  • the level of the water in the cistern is preferably controlled by a switching means queried, when the tank is full, the second pumping device for filling the cistern operated with waste water by a control device or at empty tank the inflow of waste water from the tank through the control device closed and the inflow of fresh water or filtered other water, such as rainwater, opened in the toilet cistern.
  • a switching means queried, when the tank is full, the second pumping device for filling the cistern operated with waste water by a control device or at empty tank the inflow of waste water from the tank through the control device closed and the inflow of fresh water or filtered other water, such as rainwater, opened in the toilet cistern.
  • This means that as little fresh water as possible is used for flushing the toilet used. In general it will be sufficient to use the collected one Use wastewater for flushing toilets.
  • the wastewater from a sink in the bathroom is particularly preferred, in a toilet room, in a kitchen or laundry room or that too Pump water from a washing machine, dishwasher or other household wastewater generating device rather than into the sewer system pumped into the tank and used from there to flush the toilet.
  • a washing machine, dishwasher or other household wastewater generating device rather than into the sewer system pumped into the tank and used from there to flush the toilet.
  • there are further inlets and outlets from the individual water consumers to the tank but it turns out to be special advantageous, of all fresh water consumption, the resulting wastewater continue to use to achieve better efficiency.

Das Level switching means 25 switches, controlled by the control device 50, the first pump device 26. If the float switch 41 in the tank 40 Signal that the tank is not completely full, so the float 43 is not applied to the upper switching element 46, is by the level switching means and thereby by the control device 50 for the first pump device 26 Pump signal given. The waste water from the tub is therefore through the lines 24 and 30 conveyed into the tank 40.
