AUTOMATIC EMPTYING DEVICE FOR TIMED FAUCETS

DESCRIPTION

OBJECT OF THE INVENTION

The present invention relates to an automatic emptying device for timed taps, the purpose of which is to evacuate any volume of water retained in the circuit between the faucet and the shower head and thus ensure that no water is retained in the said stretch.

The water that is evacuated by the device of the invention, will be properly channeled to a drain circuit intended for this purpose, or so that it falls directly to the shower tray, always depending on the type of installation so that in any case, the part of the referred circuit is completely empty.

BACKGROUND OF THE INVENTION

As is known, a timed tap, preferably applicable and mainly for public uses, incorporates a mechanism designed to automatically cut off the water after a pre-established period of time, once the user has pressed to put it into operation. . That is to say, a timed tap is one that, once operated by the user, does not care about having to turn it off, not as it should in a traditional tap.

Well, this type of faucet offers a comfort of use, much appreciated by the user

or people with decision-making capacity when evaluating an installation.

Its reason for being is saving water, since it prevents the tap from remaining open for a long time if the user forgets to close it, or voluntarily does not do so to continue enjoying the water. A very typical case occurs in showers in gyms where it is common for the user to rest with his back on the tap button and stay long periods of time showering with hot water.

Likewise, in public establishments such as schools, shopping centers, prisons, gyms, public swimming pools, etc., these types of situations occur regularly.

excessive.

Well, despite all the known or listed advantages of the faucet

timed, there are frequent demands for new technical contributions, required by new needs, ownership of establishments, architects, national or autonomous organizations, trends, etc.

The current awareness in many areas of society about water saving, means that we must permanently incorporate technical solutions to this type of faucet, which contribute to achieving additional percentages of water savings.

Nowadays, it is also necessary to incorporate systems that avoid water stagnation in the supply circuit, which favor the appearance of bacteria such as the so-called “legionella”, so it is essential that sanitary facilities have automatic mechanisms or processes that prevent these scenarios.

As is known, the bacteria called "legionella" develops especially in stagnant waters and in a certain temperature range, so that if the water is also sprayed, as is the case with a shower, there are many possibilities that the vapors generated Be inhaled.

If this inhalation is carried out by people with a weak immune system for any circumstance, the chances of them contracting the disease are very high, so it is a serious problem that occurs with some frequency especially in prisons, where they may exist dependencies that remain unused for long periods of time and others that do not have it daily, so that the water that has been retained since its last use in the circuit, between the shower faucet and the sprayer,

It is an adequate pond that propitiates and favors the aforementioned situation.

Although there are different systems on the market that in one way or another alleviate this problem, current systems refer to external valve assemblies that are coupled to different types of faucets, with the problems and inconveniences that derive from them, however, a similar automatic drainage device integrated in timed heads or faucets is known, whose utility model is ES1099381U, whose purpose is to evacuate any volume of water retained in the circuit, ensuring that no retained water remains in it.

DESCRIPTION OF THE INVENTION

The automatic emptying device that is recommended has been conceived to solve the above-mentioned problem, in a simple but highly efficient way, so that the device in question is based on the corresponding rod of the tap opening and closing button, It has a section of different diameter and that moves axially in a bushing with a gasket that in the position of descent of the tap stem, by pressing this, establishes a tight seal that prevents the outflow of water to the outside, while in resting position of the button the rod is in a high position and in a certain location it has a groove to form a gap between said element and the bushing itself, allowing water to flow out of the tap.

On the other hand, the cap incorporates a seal that allows the passage of water to

the corresponding chamber, while in the upward position that joint acts by pressing on the neck of the tap button to prevent the passage of water from the inlet chamber to the outlet chamber and the outside of the tap.

Based on the aforementioned characteristics, when the faucet is intended for opening or closing a shower head in the case of closing, the section of pipe that extends between the tap head and the shower head is automatically evacuated, that is to say emptying

In short, by means of the device of the invention, when the shower tap is pressed, image6 after a preset time (timing), usually around 25

image7

seconds.

After the passage of that period of time, the tap stops supplying water to the sprayer of the

5 shower and it is then when the water is automatically evacuated out of the circuit, thus preventing the water from being retained in the section, between the tap and the sprayer, so that the water that is evacuated is properly channeled through a Drain circuit for this purpose, or it will fall directly to the shower tray, depending on the type of installation, so that part of the circuit referred to above is completely empty.

In addition, the device of the invention constitutes a kind of by-pass that will be incorporated directly into the head or tap mount, contrary to what traditionally occurs where water evacuation systems are additional elements and external to the head of the tap.

15 Thus, it is a device that can be easily installed in timed faucets existing in the installation, simply by changing the tap head without performing any work and without having to temporarily close the installation to perform tap replacement works, adaptation, etc.

PREFERRED EMBODIMENT OF THE INVENTION

According to the aforementioned figures, and specifically in relation to Figure 1, the automatic emptying device object of the invention is applied to a timed tap head, including a push button (1) with a rod (4) having a section, smaller in diameter than an intermediate section (4 ') from which, the area of the rod itself (4) decreases in diameter until it reaches that of the initial section and ends in a seal (6) to establish the closure.

The reduced area corresponding to the section of the rod (4) has a circular groove similar to a "V" (4 ') that in the rest position, that is to say the button (1) and therefore the rod (4) establishes a clearance (13) between the stem section itself (4) and a bushing (5) in which the rod (4) is axially movable, and whose bushing (5) incorporates a sealing gasket (6) that fits over the section of the rod (4) referred to so that in the down position, that is to say pressing the head, prevents the passage of water

from the exit chamber (8) to the outside, through the corresponding clearance (27) and established in the socket (5).

The bushing (5) incorporates a gasket (6), which performs the sealing of the head on the faucet body and to seal the exhaust chamber (8) of the water, through the faucet body, until reaching the outlet through the slack (2).

In the body of the tap or head itself, an inlet chamber is established

(11) which is closed by the gasket (9), when it rests on the seat (12), in the position

of raising or resting of the button (1), as seen in the left half of the section of figure 1, while in the lowering position of the rod and therefore of the button (1), the water, through the inlet chamber (11) reaches the outlet chamber (7), through the passage (18) established between the section (2 ') of smaller stem diameter (21) and the body itself where the seat (12) is made ) of the seal (9).

image11

The head also includes a spring (15) for the recovery of the button (1) at the moment when it is stopped pressing on it and to carry out the opening and closing phases.

According to the characteristics mentioned, the operation is as follows:

Phase 1: When the button (1) is activated, the following events occur:

10 rod (4) axially travels a travel section shown in figure 1, and corresponding to a pre-established section, so that in this case the sealing gasket (6) is fitted to said rod (4) by configuring a closure which prevents water from flowing through the clearance (13, 21 and 2) between the slit (13) of the rod (4) and the seal (6), thus preventing the outflow of water, in turn, the board (9) has

15 separated from its seat (12), providing a passage of water (8 and 7), from the inlet chamber (11), flowing through a chamber (18) to reach the outlet tube (17) of the sprayer ( 23), when the head with the described device is applied to a shower, as shown in Figures 2, 3 and 4.

20 Phase 2: When the push-button (1) is released, that is to say no more pressure on it will start its recoil by means of the force provided by the spring (15), causing the rod (4) to retract and finally set in resting position, performing this process in a pre-established period of time called “timing”, and in which it has occurred

25 the following: the closing gasket (9) has rested on the seat (12), cutting off the flow of water through the passage (18), so that however this flow

(19) referenced in Figure 3 has been cut, the water has stopped flowing through the holes (24). The water chamber (18) has been filled to its level (16) represented in Figure 2, and that is when the emptying of the section from the chamber (18) to the

30 sprinkler (23) begins to occur, since the rod (4) by the clearance (21) provided by its sunken area (4 '), with the seal (6), causes the clearance (13) that allows the evacuation of the Total water circulating downstream and exiting the faucet through steps 21 and 2, according to the direction indicated by the arrow (23).

image13

The effect produced is that from the closure provided by the gasket (9) onwards, the entire circuit to the outlet (24) has been free of water and will remain in this dry situation until the head is pressed again.

5 In short, the essence of the operation is determined by the joint (6) that acts as a valve and that is housed in the bushing (5) closing or not closing the passage, in combination with the rod (4) belonging to the push button (1) so that it discriminates the passage of water from the outlet chamber (8), either to the sprayer (23), or to the outside of the tap according to reference (25)

10 In accordance with that shown in Figure 1, which indicates two phases of operation where the left part, the head is at rest, that is, the tap closed and the drain valve open, while the part on the right the head is in the open position and the exhaust valve is closed, when the tap is open the exhaust valve closes and vice versa, so when the tap is opened the water is directed towards the sprayer and 15 when the tap is closed the water that has been retained between the tap and the sprinkler flows to the

outside the head and therefore to outside the tap.
