Abstract

The invention resides in a mechanism for saving water, this design comprising software and hardware. The invention describes an automated mechanism designed for saving water in conventional washbasins, which includes a robotic system controlled by a software and a mechanical system that is always active waiting to detect a user, when a user is detected by the infrared movement sensor, a signal being sent to the electronic circuit for indicating that the servomotors must be activated and the water faucets opened, a circuit of leds being useful for controlling the water temperature (cold, warm or hot) by pressing a button, said circuit of leds may send a signal to the electronic circuit, said signal being sent to the servomotors for actuating the required servomotor and the torque at which the water faucet is to be opened for letting the water to flow. When the infrared movement sensor stops detecting the user, this may emit a signal to the electronic circuit so that the faucets are clo sed by the servomotors.

Description

HANDS-FREE MECHANISM ADAPTABLE TO ANY TYPE OF WASHING MACHINE FOR SAVING WATER CONSUMPTION TECHNICAL FIELD OF THE INVENTION The invention to which we make mention belongs to the technical field of mechatronics, particularly to the technical field of automation and more particularly to the technical field of home automation.

STATE OF THE ART Currently, different types of water-saving mechanisms have been developed, most of them use batteries, which have a strong impact on the environment. Water taps (faucets) have advanced in their manufacture, in manufacturing materials such as incorporation of new technologies. Currently they are developing new products in the market more efficient as well as ecological.

Some of these types are: taps with aerator, taps with flow regulator, taps with timer or push-button, faucets with infrared sensors. Currently there are more than 100 models using some of these technologies, these systems always have a very high cost compared to the traditional models found in the market.

Making a study of the technology some patents were found that belong to the field with different technologies one is MX 180756 A registered in Mexico, which is a fluid-saving device, sensitive to pressure, this invention refers to a fluid saver, at the end of the inlet a has a diameter slightly larger than that of the tubular connection, to form a shoulder between the end of the inlet and the tubular connection, a fixed rigid washer on the first shoulder to serve as a stop for the obturator , said extreme outlet having an outer diameter greater than the tubular connection, second shoulder between said tubular connection and the outlet end, a needle-type obturator comprising a portion of the upper cylindrical body having a flange extending radially outwardly on the upper portion, and a portion of the lower cylindrical body having a needle-shaped end at its bottom, that portion of the lower cylindrical body being of a diameter greater than the cylindrical body portion, to form a third shoulder between them, and a spring that at its upper end rests on a ring of soft material inserted between said springs and the flange of the obturator, at its lower end it rests on an assembly of washers restricted to flush flow, when the obturator is pushed by the fluid towards below, by way of letting go a restricted fluid regime.

Another technology found is the MX 166751 A refers to a water saving device or other fluids, which has the same principle as the previous patent, the only difference is that it does not handle interior walls.

In comparison to these mechanisms developed by us, our system regulates the flow of water, to avoid the improper use of it, and works in an automated way by means of electric current, and only activates when the user requires it, this is why sensor means that detect the individual when he positions his hands under the water jet and closes in 3 sec. By not detecting the user.

SPECIFICATION OF THE INVENTION The present invention is based on an automated device, which has an active motion sensor waiting to detect the user, when the sensor detects the user sends a signal to the electronic circuit, this is responsible for regulating the flow of water as well as the temperature of the same by means of mini push buttons, which are placed on the tip of the nose of the tap, the electronic circuit emits a signal to the servomotors to open the keys and to the water flow, when the sensor does not detect the user the electronic mechanism sends the signal to close the keys with a response time margin of 3 sec. Minimal avoiding this waste of water, this invention is mainly aimed at the most vulnerable groups of people such as children, the elderly and disabled.

The technical advantages presented by the described invention are: • Does not use batteries.

• It can be operated with electricity and, if necessary, manually.

• The response time of the mechanism is less.

• It can be implemented in a pipeline already made.

• The materials with which the mechanism is manufactured, are less prone to fatigue.

In the other bar parallel to the tip a bar (25) of 3 cm long brass 1/4"1/16 gauge is fixed perpendicularly, in this bar will be mounted a led circuit (30) which controls the temperature of the water by means of a button with specifications in figure 8.

The Servomotors (13 and 14) have a piece of plastic that fits perfectly in the servomotor and serves as an extension to hold a metal bar of 5.8 cm long 1/4"1/16 gauge brass (17), for the servomotor that is at the front or can vary in length to 7.5 for the servomotor (24) that is on the back in the prototype, the metal bar of 5.8 cm long bronze 1/4"caliber 1 / 16 (17), is attached to another metal rod 4.7 cm long (19) brass 1/4"1/16 gauge, by means of a screw (19) 2 mm long 1 cm , hexagonal round head for Alien stainless steel key.

The bar (17) on one side is held by a stainless steel screw (29) and at the other end of the bar (17) a perforation is made at 3 mm distance from the tip, it is worth mentioning that all the perforations in the bars are at the same distance from the tip, and the bar (21) of 4.8 cm long brass 1/4"1/16 caliber, fastened by a screw (20) of 2 mm of 1 cm long, round hexagonal head for Alien stainless steel key, the bar (21) is attached to a tube (33) of 7 cm long 5/16 gauge which is embedded in the handle (37) can be welded or secured with screws, the bar (21) is joined to the tube (33) by means of a tube of 4 mm length of bronze measured 3/16, and a screw 3 mm (31) of 1 cm long, round head hexagonal inlet for Alien stainless steel key.

It works in the same way with the handle on the other end of the key (16, 18, 19, 22, 23 and 24).

In the bars (3 and 4) a plate (15) of 4.5 cm long brass 1/2"1/16 gauge is mounted which is placed as a backup of the servomotors, in this plate the integrated circuit is mounted ( 35), the specifications are found in figures 6.
