Description

DESCRIPTION

Automatic washing machine with recycled water.

The present invention refers to a device to be installed in any of the existing automatic washing machines or in those of new manufacture in order to recycle the water used in certain washing phases for its use in a different phase with the consequent saving of water . It also incorporates a short washing program that directly affects energy savings.

Sector of the technique to which the invention refers

The invention presented affects the Textile Sector, Textile Treatment or similar chapter, Laundry, with regard to household appliances for washing clothes and their accessories, influencing, from an industrial point of view, the manufacture of automatic type washing machines. domestic or high volume.

Background of the Invention

The use of automatic washing machines is widespread throughout the world and in all layers of society, so any innovation that is introduced in this type of machine has a worldwide impact and small savings in a private house or in companies of washing is a major overall savings.

Automatic washing machines have brought about a very significant reduction in housework, as it advantageously facilitates the washing of clothes, which is a staple operation.

Its fundamental component is an electric motor that turns a drum with water and detergent. Possible innovations are related to the operation of the motor, with specific speeds in each washing phase, with the washing programs that regulate the entry and exit of water, its temperature, the contribution of detergent doses and some other complementary ones. All this with full automation.

It is well known that, for a very long time, it was normal to wash clothes by hand by scrubbing and hitting them on boards on the banks of rivers. These methods continued to be used until the beginning of the 20th century, because the electric washing machine, invented by Alva Fisher, became widespread when electricity became a common service. However, the origins of this appliance date back to 1780, when Robinson of Lancashire patented a machine that washed and drained clothes. Two years later, Henry Sidgier invented a manual device, consisting of a wooden barrel and a crank. In 1858, the American manufacturer Hamilton Smith added a gear to the drum that allowed it to rotate in both directions. In 1880, in an attempt to massify the washing and drying of clothes in Crimean hospitals (Ukraine), another machine was built that did both functions. Finally, in 1901, the first electric washing machine appeared, a precursor to the one we use today, thanks to Alva Fisher. This inventor applied an electric motor to a metal drum. Regarding the invention of the automatic washing machine, its merit is disputed by the companies Bendix Corporation (1937) and General Electric (1947). In any case, these were expensive and uncomfortable (the clothes had to be drained through two rollers that were on top) and it was necessary to wait for the end of the Second World War to attend the takeoff in the sales of the washing machines.

In the 1960s, some technological innovations were incorporated, such as the mechanical drum, spinning and a timer control. Years later, thanks to the systems computerized, the microprocessor began to be used to control the operation of the different washing options.

Today the novelties are focused on the control systems, in the type of controls based on keypads and touch screens, centrifuges at various speeds, location of the loading nozzles, prior control of the weight of the clothes, silent motors and other similar .

The invention presented in this document is related to saving water and energy.

Summary description of the invention

The present invention, as it has been exposed previously, refers to a device that, installed in any of the existing automatic washing machines or in those of new manufacture, allows to recycle the water used in certain washing phases for its use in a different phase. with the consequent savings. By including a short program, it also achieves energy savings.

To achieve this objective, the most important thing is to add an auxiliary tank to any washing machine and complement it with the installation of pumps that carry out the transfer of water according to the cycle set by the main programmer or from a complementary control panel.

The inventive washing machine has two pumps installed. The first is the one that already exists under normal conditions, being complemented by a two-position solenoid valve. In one of the positions, the dirty water is directly expelled to the sump and in the other position, the rinse water is redirected to the auxiliary tank. The second pump is intended to fill the washing machine by taking the water from the auxiliary tank.

In the rest of the phases, where it is necessary to fill the drum with clean water from the network, the water enters directly thanks to the pressure of said network.

The operation in detail is described in the section of the preferred embodiment by the inventor.

The washing machine of the invention is complemented by a short program that executes the complete washing in about 45 minutes, which results in a significant saving in electrical energy when compared to the usual programs that last for about two hours. Brief description of the drawings

Two schematic figures are included to facilitate understanding of the invention.

Detailed explanation of an embodiment of the invention

Automatic washing machine with water recycling, which has components that, installed in any of the existing automatic washing machines or those of new manufacturing, allow the recycling of the water used, in certain washing phases, for its use in other phases with the consequent savings . By including a short program, it also achieves energy savings.

In a preferred embodiment by its inventor it is a washing machine (1) of the usual ones on the market, both front-loading and top-loading, of which have a program wheel (2), with washing button normal, detergent drawer (7), drum (8), filter (9), and M pump (10) and drain pipe (13) in addition to other elements including the electric motor, electronic components, controllers level and others.

This auxiliary tank (1) is coupled to the rear, side or even inside, increasing the dimensions of the external casing, an auxiliary tank (15), an N pump (16), an A solenoid valve (6), a solenoid valve B (12), a recycle wash button and a series of connecting pipes as described below.

In (Fig. 1) the washing machine (1) is represented with its elements arranged to wash according to the usual cycles.

The water is taken from the mains water inlet (5), after acting on the normal washing button (3), which places the solenoid valve A (6) in the position indicated in said figure, giving way to the detergent drawer ( 7) to then go directly into the drum (8). The washing process is started according to the chosen program, leaving the water from the drum (8) through the filter (9) to be driven by the M pump (10) towards the drain pipe (13) passing through the common pipe (11 ) and by the solenoid valve B (12) oriented as indicated in (Fig. 1). This process continues until the end of the chosen program. When you want to prepare the washing machine (1) to do washes with recycling, you act on the washing button with recycling (4) in which case, the process is similar to the previous one until you reach the rinse phase in which the The water is quite clean and is therefore usable for other washes. At that moment, the program causes the solenoid valve B (12) to change its position and to position itself as indicated in (Fig. 2) in such a way that the water coming from the drum (8), filter (9) and common pipe (11) is poured into the auxiliary tank (15) having passed through the loading pipe (14).

In the next wash, the program itself is ready for pump N (16) to start, propelling the water from the auxiliary tank (15) to the detergent drawer (7) through the recycled water inlet pipe (17) and by the solenoid valve A (6), oriented as indicated in (Fig. 2). This almost clean and somewhat soapy water enters the drum (8) initiating a wash that produces dirty water to be poured through the drain pipe (13) for which the programmer changes the position of solenoid valve B (12).

Depending on the soiling of the laundry that has been introduced into the washing machine (1), another recycling wash can then be carried out until the end of the operation. For this, it is necessary that there is a sufficient quantity of water in the auxiliary tank (15), and there is a level control (18) that indicates this. Otherwise a wash is started by taking clean water through the mains water inlet (5) and again recovering the water from the rinse phase in the auxiliary tank (15).

The washing machine (1) is prepared to carry out a short program in order to make economical washes with energy savings.

It is not considered necessary to extend the content of this description for a person skilled in the art to understand the scope and advantages derived from the invention, as well as to develop and put into practice the object of the same. However, it should be understood that the invention has been described in accordance with a preferred embodiment thereof, so that it may be subject to modifications without impacting or involving any alteration of the basis of said invention. That is to say, the terms in which this preferred description of the invention has been exposed, should always be taken in a broad and non-limiting manner.
