Description

Device for separating water from a bathroom into service water (grey water) and dirty water (waste water) in order to store the slightly dirty grey water under the bathtub and use it for flushing the toilet.

DESCRIPTION

The invention relates to a device for saving drinking water when flushing the toilet by using slightly contaminated grey water from the bathtub or shower, which can be differentiated by means of a device in the drain into more heavily contaminated waste water or slightly contaminated water that can be used for flushing the toilet without further cleaning. This is achieved according to the invention by a device in the drain pipe of the bathtub or shower (see drawings 1-3) which has three functions: closing the drain in the middle position and optionally opening the inlets to the tank or to the sewer system.

The operation of the hemispherical valve body is conveniently carried out via a rotary knob on the tub overflow using two gear and rack segments (drawing detail A) which are connected to one another via a Bowden cable (drawing 4), and which transmit the rotary movement to the hemispherical valve in a ratio of 1:1.5.

The hemispherical valve sits in a double-lip seal which, due to its shape, both closes the tub to both drains and separates the two drainage systems from each other (Figure 5).

It is advisable to use the existing cavity under the tub to position a tank (drawing #+6+7). The usual tubs allow a tank volume of around 120 l. The tank shape, installation and function of a pump, level monitoring and control can be seen in drawings 8+9. The tub overflow is directly connected to the tank.

The tank must be fitted with an overflow and an odor trap on the overflow to avoid contamination from the sewage system. The toilet flush is modified as follows: The drinking water inlet is integrated with a commercially available solenoid valve (washing machine, dishwasher), which is opened when there is no gray water in the tank, and is de-energized when the cistern is full. In addition, the pump control should be designed in such a way that after 14 days of non-use of the system, the gray water is pumped out of the tank via the cistern overflow using the feed pump.
