Tandem Washing System Configuration For Recycling Detergent & Water

Abstract

A tandem configuration of automated washing machines is disclosed. A microprocessor controls solenoid valves to direct effluent of each selected cycle of one machine, into another machine for reuse. Both the machines operate in tandem applying pre-set microprocessor logic, which is further programmable for various options, keeping interlocking features Intact. By placing the washing apparatus on rooftops, further recycling is achieved.

Description

FIELD OF INVENTION [0001]This invention relates to a detergent and water saving device associated with automatic washing machine configurations. The invention particularly relates to a tandem washing system configuration.[0002]Broadly the invention makes use of automatic washing machine technology for application in domestic, community, commercial and industrial uses such as in homes, hotels, laundry services, offices and factories etc. The invention by its application relates to environment pollution technology.BACKGROUND OF THE INVENTION [0003]In a typical automatic washing machine, there are various cycles for example Pre-wash, Wash, Rinse and Spin, controlled through a programmable integrated circuit associated with a variable speed electric motor, solenoid valves and other electro-mechanical means. In such machines an electric water heater is also provided. These various cycles may be programmed as per the requirement of the washable load and availability of resources like wate...

Benefits of technology

[0007]A further object of the invention is to provide a tandem washing system configuration comprising at least two automatic washing machines of identical construction being operably connected and controlled by a single system controller allowing separate recycling of grey water generated in each cycle.

[0008]A still further object of the invention is to provide a tandem washing system configuration in which the constituent automatic washing machines can be operated at tandem depending on wash-load, type of washable material, available resources, thereby optimising the resource consumption.

[0009]Yet another objection of the invention is to provide a tandem washing washing system configuration in which storage of grey water is eliminated leading to stoppage in growth of pathogens, thereby acting as an environment friendly washing system.

[0011]Accordingly there is provided a tandem washing system configuration comprising at least two automatic washing machines of identical construction disposed parallely or vertically adjacent to each other being flowably connected via a channel means having a two-way solenoid valve, each of the two automatic washing machines having individual tap water inlets separate effluent drainage outlets disposal trays containing washing chemicals, individual heating devices, separate processors, and identically designed rotatable means. The system configuration is provided with a micro-processor-based controller which causes the second automatic washing machine to use as an input the discharged water of at least one cycle of the first machine transmitted via the interconnected channel by means of the two-way solenoid valve. The controller being operable to cause the automatic washing machines to function at tandem upon selection of any of a plurality of available attributes in respect of wash cycle, wash load, washable material, intended consumption of resources, selected time and duration for operation, thereby optimising the operational inputs and improvement in wash quality.

Problems solved by technology

As a result, there is a heavy use of resources and subsequent discharge of used water including various quantity of detergents and impurities.

The prior art devices disclose storage of certain effluents of washing machine generally known as grey water, which however is restricted to rinse water only having less detergent.

None of these prior art devices is suitable for economic use of resources due to additional requirement of constructional and plumbing features.

Moreover, longer storage of used water may lead to growth of pathogens.

There is no saving of detergent or input energy.

On the whole, adverse cost-benefit ratio of the prior art devices preclude them from large scale application.
