Description

Technical sector

The present invention relates to an apparatus that can be installed on any toilet, whether domestic or public.

State of the art

At present there is no device to know the water consumption of a toilet. Today's toilets allow two buttons of different sizes to be pressed and, depending on which one is pressed, they evacuate one quantity or another of water, however, it is not possible to know the cumulative consumption after a while.

At the moment the control of the water that enters a cistern is done by means of a mechanical system based on a buoy in such a way that when the buoy is below an established water level it allows the water to enter and at the moment when the buoy reaches This level closes the entrance. This system has the disadvantage that if it fails and does not cut the water inlet to the appropriate level; the water could reach the level of the overflow (drain in the cistern so that the water does not exceed a certain level) that these cisterns possess causing a loss of water. Although not at high levels, this is a common problem that can cause small losses of water that over time reach significant magnitudes.

In addition, the tanks must remain tight as long as the user does not press one of the download buttons. In the moment in which said tightness is lost, which can occur mainly due to wear over time, another cause of water losses would occur. Currently there is no system that allows to know the users of the toilet said problem.

Explanation of the invention.

Therefore, the present invention has the task of presenting an apparatus that allows to know the water consumption of a toilet cistern over a configurable time. In addition to preventing water losses from the overflow and warn in case of losses in the tank due to lack of tightness.

For this it would be necessary to install a system that checks the water level in the tank at all times. By means of a solenoid valve that would be installed in the water inlet, it would be regulated that no more water should enter than is due, that is, that at no time the level of the overflow was reached. In case the water level in the tank drops without the user pressing any button, it will be known that there are losses. Likewise, a screen would perform the function of offering the user all the information about the entrance of water in the tank and possible losses, while a microcontroller would act as a brain receiving the signals of the volume of water in the tank and controlling the solenoid valve and the screen .

In this way people can know the consumption of their toilets and thus it will be possible to raise awareness about the consumption of toilets so as not to waste water on them. Overflow losses could also be avoided and users could be notified of losses in the toilet tank.

Detailed presentation of an embodiment of the invention.

For the preferred embodiment of the invention, it is essential to understand the operation of the water level meter. For this, a multipoint water level switch (3) will be used, which comprises three points that are placed at different levels of height and warn when the water is above each of them. The three points would be placed as follows: one at the base of the cistern that allows to know when it is empty (it would be the bottom point), another intermediate point would be placed somewhat above the level at which the water is left when the button is pressed of less evacuation of the toilet and another at the point of maximum usual filling of the tank that would be the top point.

Knowing the water level changes, thanks to the multipoint switch, it is possible to know the consumption of the toilet. There will be two possible consumptions, the minor, when it passes from the upper point to the intermediate and the greater, when it passes from the upper point to the lower one.

By means of the microcontroller, it will be possible to accumulate the water consumption, which is known by the level changes, over a configurable period.

On the other hand, the solenoid valve will prevent overflow in the filling of the tank after the evacuation closing when the water reaches the level of the upper point.

Finally, in case the water level lost the upper point without lowering below the intermediate point in a short time, it will be understood that the toilet tank is leaking and will be notified on the screen. This is because if the water level drops because a user presses any of the buttons, in an immediate time he will lose the upper and intermediate levels. However, if the upper level is lost but not the intermediate level, it means that there is an anomaly in the cistern that causes water loss.

As can be seen in Figure 3, the multipoint switch (3) will be placed inside the tank that indicates when the water level is at one of the three points of interest - upper, intermediate and lower - or This will send such information to the microcontroller located on the screen (2).

As can be seen in Figures 1 and 2, the invention will have a screen (2) that will include a microcontroller and an electrovalve (1) located in the water inlet to the tank.
