Device for Throughfeed of Greywater to a Water User, Greywater System Provided Therewith and Method for Applying Same

Abstract

The invention relates to a device for throughfeed of greywater to a water user, including a housing for receiving therein greywater supplied via a greywater feed, a first flush pipe extending downward from the housing and connected directly to a sewer outlet, and a second flush pipe extending downward from the housing and connected to a water user. The invention further includes a greywater system provided with such a device and method for applying same.

1 . A device for throughfeed of greywater to a water user, comprising:
 a housing for receiving therein greywater supplied via a greywater feed;   a first flush pipe extending downward from the housing and connected directly to a sewer outlet; and   a second flush pipe extending downward from the housing and connected to a water user.   
     
     
         2 . The device as claimed in  claim 1 , together forming a modular unit which can be arranged on a water storage unit. 
     
     
         3 . The device as claimed in  claim 1 , wherein at least one of the flush pipes is controlled by a solenoid, wherein the core of the solenoid is connected to a spring. 
     
     
         4 . The device as claimed in  claim 3 , wherein the solenoid is further provided with a permanent magnet. 
     
     
         5 . The device as claimed in  claim 4 , wherein the permanent magnet is arranged in the core of the solenoid. 
     
     
         6 . A system for reusing greywater, comprising:
 a collecting reservoir for collecting therein greywater supplied via a water feed;   a storage tank for storing water;   siphoning means for siphoning water from the collecting reservoir to the storage tank; and   a device for discharging stored water to a water user therewith comprising:   a housing for receiving therein greywater supplied via a greywater feed;   a first flush pipe extending downward from the housing and connected directly to a sewer outlet; and   a second flush pipe extending downward from the housing and connected to a water user.   
     
     
         7 . The greywater system as claimed in  claim 6 , wherein the siphoning means comprise:
 a siphon connection for siphoning water collected in the collecting reservoir from the collecting reservoir to the storage tank;   pressure regulating means for thereby regulating the pressure in the storage tank, with which possible overpressure in the storage tank can be relieved so that siphoning of water from the collecting reservoir to the storage tank can take place; and   wherein the siphon connection is arranged substantially in a middle zone B of the collecting reservoir which is arranged substantially upright.   
     
     
         8 . The greywater system as claimed in  claim 6 , wherein the collecting reservoir and the storage tank form part of an integrally manufactured water storage unit. 
     
     
         9 . The greywater system as claimed in  claim 6 , further comprising:
 a water user, particularly a toilet, not having its own water reservoir; and   wherein the device for discharging stored water is adapted to thereby discharge stored water to the water user for immediate use thereof without interposing of a water reservoir of the water user.   
     
     
         10 . The greywater system as claimed in  claim 6 , further comprising:
 determining means for determining the quantity of water stored in the system; and   influencing means for thereby influencing the quantity of water flowing from the storage tank to a water user.   
     
     
         11 . The greywater system as claimed in  claim 6 , wherein the collecting reservoir comprises a volume of at least 10 litres so that sufficient greywater for at least two successive flushes can be stored therein. 
     
     
         12 . The greywater system as claimed in  claim 10 , wherein the influencing means comprise a throttle or pinch valve controlled by a control system of the greywater system. 
     
     
         13 . The greywater system as claimed in  claim 10 , wherein the influencing means, controlled by a control system of the greywater system, adjust the period of time for which the flush opening is open. 
     
     
         14 . The greywater system as claimed in  claim 6 , further comprising:
 a conduit system between the storage tank and a water user located at some distance; and   a pump for thereby pumping water out of the storage tank to the water user.   
     
     
         15 . The greywater system as claimed in  claim 14 , wherein the basic volume of water present in the storage tank is increased for each additional water user connected to the system. 
     
     
         16 . The greywater system as claimed in  claim 15 , wherein at least 10 litres of water is adhered to as basic volume for two water users.
