Description

Consumption installation for sanitary water.

Object of the invention

The present invention relates to a sanitary water consumption facility, which has been especially conceived in order to achieve a drastic saving in said consumption.

More specifically, the invention presents focuses on the consumption of hot water, and the object of the invention is to get the water out through the corresponding tap to a adjustable temperature, and also that consumption does not occur until the moment when the water reaches said temperature at the point outlet, that is in the aforementioned tap.

The invention is essentially located in the area of domestic water consumption, but it is equally applicable to hotel facilities, and in general there where there is consumption of hot water on a human level, as per example for showering, for teeth washing, for scrubbing dish manual, etc.

Background of the invention

In a water supply facility health, as well as in any of the other cases mentioned in In the previous paragraph, there is a general supply pipe of logically cold water, which forks in two, so that one of the latter comes directly to the different faucets or points of installation consumption, while the other goes through a heater that can materialize in a gas boiler, a thermos electric or any other device capable of heating water, of so that at the time of consumption at a certain point of the installation, and by means of respective faucets or a mixer tap mix the cold water with the hot water, so that it goes out to the temperature desired by the user.

Logically the water in the pipe that relate the heater to the tap in question is at room temperature, that is cold, so that once has made the tap opening there is a time or so important during which the cold water existing in this conduction it is replaced by the hot water generated in the heater, not having hot water in the tap until this water hot does not reach it, which means a loss of water so much more considerable the greater the distance between the boiler and tap, distancing than in the case of housing single family can become very considerable.

In addition, hot water reaches the tap at the temperature generated by the heater, usually much higher than the consumption temperature, so that acting on cold and hot water, simultaneously, it is reached the desired temperature, but logically for as long as is performing this maneuver is also losing water.

On many occasions, such as when try to brush your teeth, the water consumed to reach the tap the appropriate consumption temperature, can be several times higher than the water actually consumed in said washed.

It follows from the foregoing that the water losses that occur today until achieving that the water comes out at the desired temperature, they are very considerable, which is an important problem considering account of the increasing cost of water produced by weather conditions, that is, because the rainfall It is increasingly scarce.

Description of the invention

The consumption facility for sanitary water that the invention proposes resolves in a fully satisfactory manner the problem described above, reducing the waste of water, and this is because in that installation the water comes out from the tap as long as it does not reach the temperature of Expected consumption, as previously stated.

This is part of an installation conventional as mentioned above, that is to say with a pipe general inlet that distributes cold water to all taps the same, forked in a second branch that goes towards the heater and that from it distributes the already hot water to the cited taps, and from this basic structuring has been provided for the provision in the hot water pipe or conduit of a three-way valve, specifically a solenoid valve automatically operable by means of a control circuit, of so that through said three-way valve a return conduction to the heater.

Parallel in the conduction or water pipe cold towards the taps a second solenoid valve is established, in this case two-way, which closes said circuit in turn when receives orders from said control circuit.

The control circuit acts according to a pair of thermal sensors, one established in the conduction of hot water and other in cold water conduction, so that said circuit receives permanent information from both sensors, or What is the same, receives information on the water temperature hot and cold water temperature, and acting on the cited solenoid valves does not allow the passage of water to the corresponding tap in both mixing over and over, okay with the planned flows, it does not give rise to the temperature of consumption pre-established by the user, maintaining the hot water in recirculation through the heater, until the moment in which the control circuit determines, at the expense of signals received from the sensors, that the water temperature of Exit by the tap is the expected one, at which time the cold water line solenoid valve and valve three-way solenoid interrupts the recirculation circuit of water through the heater, and allows the direct passage of water from said boiler to the tap.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of this description, a single set of drawings where Illustrative and not limiting, it has been represented schematically a consumption facility for sanitary water carried out in accordance with the object of the present invention, in the that the water heater consists of a boiler and in which simplification reasons only one of its faucets

Preferred Embodiment of the Invention

In view of the review figure you can observe how the installation that is recommended is constituted, Like any conventional installation, through a pipe General (1) cold water supply, provided with the usual stopcock (2), pipe (1) that forks in two with another branch (3-3 '), one (3) that goes directly to each one of the taps (4) of the installation, and another (3 ') that connects to a heater (5), which can materialize in a boiler such as in the example of practical embodiment of the figure, in a electric heater or any other similar element appropriate, emerging from said boiler (5) another pipe or conduit (6) that goes to the taps (4), where it finally Mix with cold water.

Well, according to the invention, in the hot water pipe (6) that relates the boiler or heater (5) with the taps (4), a solenoid valve (7), of three ways, and a thermal sensor (8), so that said valve solenoid (7), depending on its working position, connects the pipe (6) with the tap (4) through the classic conduction (9), or establishes a return circuit to the heater itself (5) to through another pipe (10) that connects to the branch (3 ') of the main pipe (1).

For its part in the cold water pipe (3) it it also establishes a solenoid valve (11), in this case of two ways, and a thermal sensor (12).

The solenoid valves (7) and (11) are controlled, at the expense of the information provided by the respective thermal sensors (8) and (12), by a circuit of control (13), which in the figure appears connected to said elements by wiring (14) through which it receives information from  the sensors (8) and (12), and wired (14 ') through which acts on solenoid solenoid valves or valves (7) and (eleven).

For safety reasons the control circuit (13) works at low voltage, so the contest is necessary of a power supply (15) that converts the mains voltage, generally alternating and 220 V, in low direct current voltage, such as 6 or 12 V.

According to this description and as already noted above, the operation of the installation is the next:

When the demand for tap water occurs (4) and once the consumption temperature in the circuit has been programmed control (13), said circuit detects the temperature of the water that circulates through the pipeline (6) and the one that runs through the pipeline (3), to through respective sensors (8) and (12), and since in that moment the hot water has not yet reached the tap, close the solenoid valve (11) and positions the three solenoid valve tracks (7) in the closed position towards the tap, that is to say in position of closing for the pipe (9) and in position of opening or exit towards the return pipe (10), bringing the water that theoretically it would have to reach the tap (4) return again to the heater (5) until it reaches a predetermined thermal value, that in combination with the thermal level of cold water that found in the pipe (3), would result in a temperature of the mixture according to the one planned for consumption.

At this time and without the occurrence of less water loss, the solenoid valve (11) opens and the three-way valve shifts position by closing the pipe return (10) and opening the consumption pipe (9), so that through the tap (7) water begins to flow exactly to the expected temperature
