DESCRIPTION

First certificate of addition to the main patent P201500265 hands-free device by sensor or wireless control for the control of water flow in a tap.

The present invention includes improvements and extensions of the main patent referred to a series of elements that coupled to the sink and countertops of domestic type allows to activate and deactivate the water flow of a tap without using the hands, either by means of a sensor, microdetector or micropulsador, either through a wireless system. It can be installed in industrial systems, in the toilets and showers used in domestic bathrooms that are adapted for this purpose. With this, it is possible to have hands free all the time and that disabled people can have an adequate access to the taps. The system in general also has a longer life since the mobile parts have less wear and less damage apart from saving water.

It fits into the industry of complements for the supply of water or any other element.

Thus, the present invention presents a new operating system since instead of using the hands we use the support or approach of the front part of our body, since a simple movement is sufficient to open or close the tap. The activation system can use, a sensor, microdetector, or micropulsador this can be installed or not in the front of the sink detecting the approach and activating the opening or closing of the tap and cutting the flow of water when the user retires a few millimeters from the sink. With this the tap is kept the last time open. The transmitter can be located or not located in the front of the sink, the device uses the transmission technique by radioelectric signal tracking being its range for short or very short distance, it communicates with the receiver and at the same time with the electrovalve which facilitates the opening or closing of the tap, cutting off its flow of water when the user retires a few millimeters from the sink. The system used by wireless transmission gives greater security, in its installation and communication since it eliminates all types of wiring. The transmitter is a component that is hermetically closed. The device has an electrical circuit installed inside a box, which contains the receiver circuit, which has a plug to be connected to the 240v electrical network.

The drawbacks of the main patent are the following:

The system by nature requires a wiring, which in most facilities is complex in kitchen furniture and bathrooms, because each manufacturer is different and this complicates installation, not giving security in its operation as they have to pass the cables very close to the water inlet and outlet pipes. Therefore, the system used previously is not a secure system. This decision, moves us to the facts.

Existence of failures in cables, connectors and other components, these are inevitable in a kitchen cabinet where doors open and close constantly and where there may be leaks of water with its consequent risk.

With the following additions they are solved;

ADDITION 1.- A technique for transmitting radioelectric signals for short or very short distance is incorporated into the device, said technique consisting in that the transmit signal of the emitter is projected to the ground. Having its own identity and being all this a special system of transmission of signals since the waves travel, or slide on the ground.

ADDITION 2.- A fixed frequency and fixed power are also incorporated into the device, this being achieved by continuous interactions or divisions between two or by itself of said base frequency that is transmitted, and the fixed power is achieved by maintaining the length of wave a stable intensity, thus achieving the decrease to the maximum margin of error between the frequency emitted and the final frequency received. The range of frequencies is wide, although 3.3 MHZ and 3000 GHZ are advisable in a non-restrictive way.

ADDITION 3.- A metallic box made of a mesh or grid is attached to the system, which has an adjustable window from the maximum opening to the total closing of the window, thus being able to adjust the signal range in centimeters.

ADDITION 4.- It is located a portable emitter can be located in the front of the sink or not.

ADDITION 5.- The device employs the signal tracking technique of short or very short distance, this technique consisting of the transmit signal of the emitter being projected to the ground, the waves being conducted through the ground, waves that are received in the receiver that should be located at a maximum distance from the ground level of 1.5 meters, thus ensuring communication.

This technique is applicable for any device that requires a wireless communication, the transmitter is a portable handling device and can be placed in the most suitable place for its use.

Preferred embodiment of the invention

A preferred embodiment is constituted from the incorporation of a sensor (2), microdetector or micropulsador, coupled to the sink and countertops of domestic type that allows to activate and deactivate the water flow of a tap (10) or other system of industrial type and in the toilets and showers used in the bathrooms. The system incorporates a transmission of radioelectric signals (9) to the whole device for short or very short distance, said technique consisting of the transmission signal of the emitter being projected to the ground. An integrated circuit that guarantees a stable frequency and fixed power is also incorporated into the emitting device (12).

A metal box (13) made with a mesh or grid is attached to the system, which has an adjustable window (14) from the maximum opening to the total closing of the window, tab for regulating the adjustment of the window (15), thus being able to adjust the signal range in centimeters. The emitter (12) is located at the front of the sink (11) or not. The device employs the signal tracking technique of short or very short distance wavelengths, the receiver (16) being located at a maximum distance from the ground level (17) to 1.5 meters, thus guaranteeing communication.
