Description

Installation for domestic hot water and faucet for it.

Object of the invention

The present invention relates to a installation to supply domestic hot water, preferably at the domestic level, although it can also be used in other facilities such as offices and Similar.

The object of the invention is to achieve a substantial water saving, preventing it from coming out of the tap the installation until the temperature required by the Username.

The invention thus falls within the scope of the plumbing in general, and particularly of the faucet.

Background of the invention

As is known, in the supply facility of water from, for example, a dwelling, the pipe coming from the General cold water supply network is split into two branches parallel, one for cold water and one for hot water, of so that in this last branch the heating element is established which can be of very different types, electric, gas, etc.

There are instant obtaining systems for hot water, materialized in powerful electrical resistors established in the immediate vicinity of the corresponding taps so that the opening of the tap brings about the simultaneous connection of resistance and, as just said, immediate obtaining of hot water.

However, the usual thing is that the element heater, boiler, be common to all faucets of the installation and be more or less away from each of them.

There are many cases in which the withdrawal between the heating element and a tap is very considerable until the point that the hot water produced in said heating element it takes a very considerable time to reach the tap, occurring a consumption of cold water totally unwanted and that has an impact on very negative way in different aspects, specifically in the water consumption, in energy consumption since wastewater that occupies the pipes when the use of it ceases is not taken advantage of and finished cooling, etc.

The applicant is not aware of the existence so far of any system or installation that is able to avoid the aforementioned problem, particularly when there is a considerable distance between the heating element and the tap, as happens in large residential buildings, when these are fed from a common tank or boiler for all they.

Description of the invention

The installation of domestic hot water that the proposed invention resolves in a fully satisfactory way the problem discussed above, so that whatever the distance between the heating element and the tap, water consumption does not start to occur until water hot reaches said tap.

The invention also concerns the tap with the that the installation mentioned is operative.

More specifically in the installation than the invention proposed between the heating element and the tap is establishes, in addition to the classic feeding pipe of this one last, a second pipe or receptacle, which resend the existing cold water in the pipe conventional faucet feed back to the element heater, until the moment when the water reaches the tap to the adequate temperature, that is hot, at which time a valve allows disconnecting the return line and connecting the access pipe to the tap outlet duct.

According to another of the characteristics of the invention, said tap has a manual valve for carrying out the water connection / disconnection maneuvers at the outlet of the tap, and also incorporates a small window occupied by a thin latex membrane or similar, which is facing and in direct contact with the hot water pipe that feeds the tap, so that the water temperature can be easily detected by supporting one of the fingers of the hand on said membrane, to determine the moment at which the actuation maneuver must be carried out on the mentioned manual valve, so that the water begins to flow out of 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 an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

In view of the figures outlined, in particular of figure 1, can be seen as the installation that Account is recommended, like any conventional water installation sanitary, with a connection (1) connecting to the general network of supply, connection from which two pipes emerge in parallel, a cold water outlet pipe (2), which directly leads the cold water to the tap (3), and other cold water inlet pipe to the heater (4), which conducts cold water to a main tank (5) for heating it, with any heating medium, said main tank (5) of hot water may not exist and be replaced by a heater of any kind conventional, in any case, provided with its pipeline hot water outlet (6), which also goes to the tap (3), where hot and cold water mix to get the temperature required by the user.

The technical problem outlined above is that, when the main tank (5) of hot water and the tap (3) they are very distant, that is, when the length of the Hot water outlet pipe (6) is very considerable, all the volume of water housed in it is cold water after a period of time after the tap is closed (3), so when solicitation of hot water consumption, the first thing that has to happen is that the cold water of said pipe (6) leave it and be replaced by hot water from the main tank (5) or heating element, which means an amount of water considerable that is wasted.

Well, according to the invention, in the installation establishes an additional return pipe (7), specifically between the tap (3) and an auxiliary tank (8), the which, in turn, is connected to the cold water outlet pipe (2) through a first valve (9) that gives preference to the entry into said pipe (2) of the water that, through a pipe of connection (10), comes from said auxiliary tank (8) against the water from the connection (1).

Moreover, in addition, and as observed particularly in figure 2, the water outlet pipe hot (6) and additional return pipe (7) are connected each other through a second three-way valve (11) and of manual actuation, so that, through a small handle (12) established in the tap body (3), said second valve (11) can establish communication between the outlet pipe of hot water (6) and the additional return pipe (7), or, close the latter and establish a direct connection between the pipeline hot water outlet (6) the outlet duct (13) of the tap.

In this way, while it is being produced the evacuation of the existing cold water in the outlet pipe of hot water (6), the tap (3) is kept closed and, once concluded said evacuation, that is, when the hot water has reached the tap (3), is when the opening of the same occurs and corresponding exit of the water to the outside.

To be able to easily verify that the Water temperature in the tap is adequate, it is expected that, next to the inlet of the hot water outlet pipe (6), from the main tank (5) or heating element, and in the tap body (3), a window occupied by a thin membrane (14) of latex or similar, which allows to detect quick and easy said temperature, by means of a tactile maneuver, with the tip of one of the fingers of the hand.
