DE2757518A1 - Water economising of washing machine effluents - by recycling part for use in flushing toilets - Google Patents

Abstract

Two drains instead of one are fitted to laundering and washing machines generally, so that by means of an electrical or electronic circuit controlling valves and a pump, the waste water can be divided into two kinds. The really dirty water goes direct to the sewers, whilst the scarcely discoloured water can be stored for use in WC's and urinals in households and in factories.

Description

Appendix 1 / description

===================== Title: Production and installation of two drainage outlets with controllable shut-offs (valves) in dishwashers or washing machines for re- or further use of water used in dishwashers or washing machines.

Field of application: The invention relates to a further utilization of the water used in households and businesses for operation and function is used by dishwashers or washing machines by having a suitable Part of the water that is used and drained does not go straight to the drain / drain pipe is fed when it has left the respective device, but first of all further useful use when operating and flushing water clossettes (toilet) and piss / urinal systems in households and businesses.

Purpose: drinking water - our food no. 1- is not in inexhaustible Quantities available. Rather, there is rule in large areas of our Federal Republic already lack of water. Most economical and economical use of drinking water is essential.

Through the further and possible use of subsets of the in rinsing or washing machines used water will not only make a significant contribution to the The water and drinking water balance has been removed from the water; also become the operator such devices enabled costs and fees for water procurement and to save wastewater treatment over decades.

State of the art and criticism: Dishwashers or washing machines are almost operated without exception with the best drinking water, are water-consuming and give the used water directly into drainpipes / drains regardless the fact that large subsets of the respective operating requirement quantities are only very are slightly contaminated and are quite suitable in systems such as flush toilets (WC) and piss / urinal basins in households and businesses. For The operation of flush toilets, urinals, etc. requires water of drinking water quality are not wasted, since in these cases the water only has the task of the The removal of human waste is incumbent.

Task: The invention is based on the task of permanent cost savings for operators of new dishwashers or washing machines by re-or.

Re-use of used, but hardly contaminated water Devices with two separate drain outlets, combined with a reduction in the To achieve water consumption at other points of consumption as well as the amount of wastewater, without being worthwhile for the procurement of the equipment or the necessary installation To spend additional costs.

Solution: This object is achieved according to the invention in that rinsing or washing machines instead of only one drain outlet two drain outlets (AS and AR). The electronic program circuit or electr. Control circuit such devices can be designed or

added that each of these two drainage outlets through valves or usual barriers can be opened or closed automatically.

Depending on the operation of a device, the water used can now be poured into A distinction is made between contaminated water and hardly contaminated water (e.g. rinsing water) and separated via the drainage outlets AS (drain ~ dirt) or AR (drain-clean) be derived.

The according to the predetermined programs of these dishwashers or washing machines Even and recurring work processes ensure correct Separation of the water used into different qualities.

The contaminated to heavily contaminated water from the cleaning and washing processes leaves the device via drain outlet AS and becomes the drainage system / drainage channel (K) fed directly.

The hardly contaminated to clean water comes out of the rinsing processes through drain outlet AR, flows through a separate pipe into a pressureless, serving as a storage tank SB.

The water is drawn from this collecting tank using a commercially available Pump (PU) with small air chamber, switching depending on pressure, via pressure lines conveyed directly to the points of consumption (e.g. water tanks at water closets). The operation of flushing devices in toilets, etc., can be carried out in the usual way take place according to installation-technical aspects. The collecting container SB receives in addition to an overflow, connected to the dirt drainage system K, a feed option from the general water supply network, shut off with a float valve and secured with return valve.

This prevents the collection container from being completely empty and one Flushing toilets etc. becomes impossible.

The unpressurized collecting container, which can be of almost any shape given, designed as a single container or as a combination container on a flushing or Washing device can be attached, is provided with a lid that can be easily closed upper opening for easy cleaning and maintenance.

Achievable advantage: Reduction of those used in the household or business Water volume and thus cost / fee savings for drinking water and wastewater treatment.

Example: With a washing machine of the usual type and operation of the same In an average household of 4 people, about 100 liters of water are used per washing process used. At least 60 of these can be reused or reused in WCIs will.

With an average water consumption, this results in one 4-person households of around 120 m3 / year a saving of 4 to weekly 5 washing processes of 60% x 100 l / washing process. x 4.5 wash cycles / W x 52 W / Y = 14,000 l / J.

14 m3 / yr of water saved corresponds to annual consumption of 120 m3 a share of 1006 x 14 around 12% 120 As in most households next to a washing machine and a dishwasher is an increase the savings to be achieved up to 25% of the annual water volume.

This means 25% less costs / fees for drinking water and the Wastewater treatment.
