DE202006005476U1 - Device for double water utilization used in the household comprises an open or closed collecting container in a floor, wall or ceiling assembly connected below the level of the service water run-offs from a bath tub, shower and sink - Google Patents

Abstract

Device for double water utilization comprises an open or closed collecting container (3) in a floor, wall or ceiling assembly connected below the level of the service water run-offs from a bath tub (1), shower and sink and a pump (6). Preferred Features: A filter (2) is arranged directly on the inlet. An automatic pump is switched on according to the service water requirement. The collecting container can be used for an average two days water consumption and is connected to the water-house connection via a float-type switch or level electrode (10).

Description

1. What is the current state

Precious Drinking water is currently being used for other purposes. In order to valuable resources are wasted.

2. What is the goal

protection of local and global water resources. Due to the double use of parts of the wastewater will save up to about 40% by the effective cost Reduction of water consumption achieved.

3. How is it achieved? (Function)

The waste water from sink, bidet (if present), shower and bath ( 1 ) are in an open, optionally also to be closed collecting container ( 3 ) below the level of the processes, eg collected in the basement. In this case, no pump is used because the promotion is done without pressure by the gravity of the earth. There is a filter directly at the inlet of the collecting tank ( 2 ). The possibly accumulating foam runs in the container over the overflow ( 4 ) into the sewer ( 5 ); the heavy components settle on the ground (by themselves).

Via an automatic pumping station ( 6 ), for example, a so-called domestic waterworks, the custom-water gets to toilet flushing when needed ( 7 ) or urinal (if available). The suction nozzle is located at a certain distance from the container bottom of the collecting container ( 3 ).

By the pressing the rinse button on the cistern e.g. (the built-in float opens the water supply line) If there is a pressure loss in the supply line, the pump switches through it and promotes so much rinse water, as needed becomes.

From time to time, of course, the sump must be freed from the mud - preferably by rinsing with this custom-water ( 6 ) via a drain valve or tap ( 8th ) to the sewer.

4. How is it achieved? (Technology)

The waste water from the bathtub, bidet, shower and washbasin is stored in a collecting container ( 3 ), which has a filter ( 2 ) is in front of it. The site must be located below the lowest level of the processes, preferably in the basement of the apartment / residential complex / company.

This floor installation, wall or ceiling mounting, depending on the occasion, possible. The container must be suitable for the storage of such wastewater (eg PE black). This should be so large that it can absorb twice the daily amount of it. At higher sewage inflow this runs over the overflow ( 4 ), which also removes the foam into the sewage system ( 5 ).

Via an automatic pumping station ( 6 ), for example, a so-called domestic waterworks, the custom-water gets to toilet flushing when needed ( 7 ) or urinal (if available). The suction nozzle is located at a certain distance (about 1/5) from the container bottom of the collecting container ( 3 ). This pumping station ( 6 ) is depending on local circumstances directly next to the collecting container ( 3 ) assembled.

In addition, once the waste water is insufficient, it must still be possible to use a float switch or level electrode ( 10 ) "normal drinking water" with a solenoid valve or tap connected to the float switch ( 9 ) can be supplied to this sump in an open system.

The advantage of this system is that at the cisterns at ( 7 ) no conversions are necessary, as when activating the flush button, the float opens the water supply line and by the pressure loss in the supply line, the automatic submersible pump ( 6 ) is activated.

Claims (5)

Device for dual water use, characterized in that it consists of a below the level of the service water drains of bathtub, bidet, shower and sink mounted open or closed collecting container in floor, wall or ceiling mounting and a downstream pump. Device according to the preceding claim, characterized that there is a filter directly at the inlet and a switchable on DHW demand automatic pump (domestic waterworks) is installed, the service water intake opening approx. 1/5 over the sump bottom is appropriate. Device according to the preceding claims, characterized in that the collecting container has the capacity of a average 2-day water usage and has a float switch or level electrode with a solenoid valve (via an open system) with the water house connection is connected. Device according to the preceding claims, characterized in that at pressure loss in the water supply to the urinal or toilet (eg if the float opens the water line by pressing the WC flush button) the automatic pump in the collecting tank can be activated. Device according to the preceding claims, characterized characterized in that the collecting tank via an overflow and a drain valve has channel asion.
