DESCRIPTION:

OBJECT OF THE INVENTION:

10

This specification refers to a patent application corresponding to an automatic stopcock of the water and gas supply to prevent leaks during periods of absence and / or non-use of housing,

15 local, ship or hotel room, or establishments.

The purpose of this system is to prevent leaks in the water and / or gas supply or in any plumbing installation carried out in homes or establishments, or thus contributing to avoid unwanted situations.

SECTOR OF THE TECHNIQUE:

The present invention is for use in all types of plumbing installations for both gas and water in homes or establishments.

STATE OF THE TECHNIQUE: 30

+ The Spanish patent ES 2 025 896 (David Moliner Vergara): "Security system, against domestic flooding or similar." claim: 1. Security system against domestic or similar floods, characterized in that it is constituted with humidity detecting elements intended to be placed on the ground or lower part of places where there may be leaks or water leaks, said detectors going related to a electronic circuit, as controlling means for its activation, which circuit is in turn constituted as a means of control and control of a possible optical-acoustic signaling system and / or of an automatic cutting system for the passage of water through the attached conduits, so that in the event of an improper presence of water in the place the detectors bring the system into operation, causing the activation of the signaling means and the cutting of the conduits.

This is a security system afterwards, once the breakdown and subsequent flooding have already occurred. It is not, therefore, a preventive system like the one advocated by the presented invention.

+ The Spanish Utility Model XJ 200502739 (Manuel

Sarmiento Perera): "Domestic digital control system for electricity, water and gas supply meters." In his second claim he cites:

2. Domestic digital control system for electricity, water and gas supply meters, according ^to claim 1 and characterized by having a personal computer connected to the automaton and intercommunicated by means of a data transmission system to the process centers of data of the offices of the supplying companies that allows you to receive orders of operations of cutting and supply replacement thanks to the presence of mechanisms based on electro-valves or power switches connected to the automaton and the supply connections.

In this case it is a control system by the supply companies that allows them to cut off unpaid supply. It is therefore not comparable to the potential of the present invention.

+ The Spanish Utility Model 1 063 176 (Miguel Ángel Villanueva Cortijo): "Central dαmótica." It consists of a two-way telephone communicator that allows the subsequent detection of a gas failure in the home:

3. Central, according to any of claims 1 and 2, characterized in that the bidirectional telephone transmitter

(11) comprises at least one connection (24) to a gas detection sensor (25) and its corresponding solenoid valve (26) to detect a domestic gas leak.

The aforementioned Model allows telephone leaks and other problems to be controlled by telephone, but always a posteriori, not affecting the essence of the present invention.

We conclude, therefore, that the existence of a system that automatically allows the cutting of water and gas circuits of a building, house or premises is necessary to avoid breakdowns during their absence.

DETAILED DESCRIPTION OF THE INVENTION:

Automatic shut-off valve of the water and gas supply to prevent leaks during periods of absence and / or non-use of housing, premises, ship or hotel room, or establishments. The purpose of this system is to prevent leaks in the water and / or gas supply or in any plumbing installation carried out in homes or establishments, thus contributing to avoid unwanted situations.

The infrastructure in question will support the system of cutting the passage of water or gas in homes or establishments (industries, premises, hotels) and can be installed in hot and cold water facilities in room bathrooms, hotel kitchens, industrial warehouses, public toilets, In short, in all those places where cold, hot water and gas can be used, this infrastructure will be composed of an automatic cut-off key connected directly to motion sensors and timers, which will preferably be placed in the rooms where the water and gas installations, eg bathrooms and kitchens, or in the access to housing, premises or rooms.These sensors will detect the movement for example at the entrance of the home and will proceed to send a signal through a relay or relays and programmer that will cause the opening of the water and gas stopcocks of the house or room. be applied simply to the desirable stay by the client without having to affect the general key of the house. Such is also the case of hotel establishments, where the unoccupied rooms can be cut without affecting the installation of the rest of the building.

The operating system would be as follows: By combining one or more motion sensors, relays and a timer, we proceed to perform jointly the installation of the components whose work process will be the following:

When the tenant enters the home or premises, his movement will be detected by the sensor, which will send an order to the relay that will proceed to open the gas and water stopcocks of the house. Once inside the tenant / s will enjoy the supply of water and gas until the timer stops detecting movement at home. Thus proceeding to the cut of the supply in this space of time in which no movement is detected, said space of time will be programmable by the customer.

- This may be applicable in the following example: we enter the house the sensor detects the movement by opening the stopcock. Then we put the washing machine to be washed, we program the timer with the time that the washing machine needs to finish the washing process, once we do this we leave the home and the cut will take place after the programmed time after the sensor does not detect movement.

The smart key is a solenoid valve that will open and close automatically based on the orders received and sent by components 2-2I-3, 4, 5,8.

The solenoid valve will close, for example, at 2.5 hours after there is no movement in the house, which means that the owner is not in the house and there is no need for water pressure in the installation ; the solenoid valve will be at rest until movement is detected in the house, after The last movement detected by the detector could take a certain time for the solenoid valve to close, leaving a minimum time for it to remain in operation since there are devices that need water consumption for a certain time and then close automatically.

EMBODIMENTS OF THE INVENTION

In a first preferred embodiment of the invention, represented in scheme 1, we have the smart key that is formed by a 2-pole thermal (1) at the entrance of the 10 A electrical panel, a motion detector (2) that It will be located at the entrance of the house or room, above the door, provided it reaches all entrances to damp rooms, bathrooms, kitchens, toilets, etc. to get the most out of it and Do not leave dead zones. The relay (3) picks up a signal sent by the motion detector and sends it to the programmer (4) in the form of an electric pulse, which uses this signal to operate proportional timers and through this timer (programmer) (4) We operate a solenoid valve (5), which will leave us the installation of plumbing with or without service, being advisable to install the electrovalve in the water inlet pipe to the house or room to cancel the maximum possibilities of breaks or leaks in the home or common areas (areas to protect from floods). In the electrical panel there are some LEDs that will indicate at all times the state of the solenoid valve, Led (6) (red) closed solenoid valve, led (7) open solenoid valve (green).

In a second preferred embodiment of the invention, represented in scheme 2, we have the option of being able to install the smart key wirelessly, ideal for renovations or existing installations, in addition to having the same features as the scheme 1 a wireless motion detector (2i) and a receiver (8) are incorporated.

In a third preferred embodiment of the invention, represented in scheme 3, it extends the entire operation of the smart key of scheme 1 (designed for water), incorporating the option of making the water and gas smart key with which it will close us water and gas faucets, after a period of time determined by the customer; This time is usually set after installation. The solenoid valves will close after the set time, after the last movement detected by the detector (2). With this smart key we will be able to close the gas passage, in case we are not at home (there is no movement in the house or room), through an electrovalve in the gas tube, we would only have gas if the room thermostat demand heat (the boiler is turned on) then the room thermostat (12) gives a signal to the relay (11) and through the contact (13) of the relay the boiler is turned on and simultaneously the contact (15) of the relay (11) gives order to the solenoid valve (10).

As the indoor gas installations service countertops, once the movement in the house or room is detected, the water and gas solenoid valves would be activated simultaneously, the timer being able to be programmed with a different closing time with respect to the water programmer since when the room thermostat of order will turn on the boiler and gas solenoid valve regardless of the movement in the house or room for as long as the room thermostat demanded heating, the boiler will remain on, we will know the position of the gas solenoid valve through mediation the Led (13) yellow.

In a fourth preferred embodiment of the invention, represented in scheme 4 there is the option of installing scheme 3 with wireless sensor.

A fifth preferred embodiment of the invention, which would correspond to the same operating schemes 3 and 4, would include all the operation of scheme 3 or 4 but with the possibility of installing a probe or a second room thermostat set, for example, to 21 ° C that would maintain that temperature whenever there was movement through the house or room due to the presence of people (in which case we would need more temperature). Stop acting once there was no movement, leaving the system at rest at the temperature set in common thermostat (which could be for example 17 ° C). With this system we would get more comfort in the home or room in question and with that more savings without having to touch anything or having to reprogram those complicated thermostats and digital chronothermostats.

A sixth preferred embodiment of the invention, which would correspond to the same operating diagrams 3 and 4, would include all the operation of scheme 3 or 4, adding the possibility of having a contact to feed a recirculation pump so as to have hot water Instantly sanitary, if the plumbing installation allows it.

A seventh preferred embodiment of the invention, which would correspond to the same operating schemes 1, 2, 3 and 4, would include all the operation of scheme 1, 2, 3 or 4 with the possibility of installing a sensor in the safety lock of the house or room so that when the entrance door to the house or room is condemned, the water and gas supply to it is cut off.

An eighth preferred embodiment of the invention, which would correspond to the same operating schemes 3 and 4, would include all the operation of scheme 3 or 4 with the inclusion at a point of the housing of a manual control that allows the cutting or ignition of voluntary form of the solenoid valves that command the passage of water and gas to the house or room.

A ninth preferred embodiment of the invention, which would correspond to the same schemes of Operation 1, 2, 3 and 4 would include all the operation of scheme 1, 2, 3 or 4 add bypass keys for both water and gas systems. In order for it to work properly we will have to have the general key (a) open and the bypass key (b) closed always, except, when there is a breakdown or lack of voltage, then we will open the bypass key (b) in order to give water service to the house or stay. We will close the key once the breakdown is repaired or the electricity is restored.

Finally, in a tenth preferred embodiment of the invention, an electronic module can be coupled to replace the relay systems explained above, which perform identical functions and controls.
