Quantified water-saving device for dual-flush toilets

Abstract

The invention relates to a quantified water-saving device for dual-flush toilets which comprises a single button (11) which, when actuated, moves an overflow pipe (3) upwards, the aforementioned overflow pipe (3) comprises: a float (5) which can maintain the device open until all of the liquid has been emptied, if no other forces are acting on the pipe other than the weight of same; and an intermittent additional weight (6) which is disposed at an intermediary height and which, once a certain quantity of liquid has been emptied, is no longer suspended as the water level falls, said action, together with the weight of the assembly and the additional weight (6), causing the discharge valve (4) to close with the remaining water being left in the cistern. Moreover, when the above-mentioned button is pressed a second time, the overflow pipe (3) remains elevated and the outlet valve (4) stays open, such that the cistern can be fully emptied since the additional weight (6) has been eliminated. For fully flushing, it is enough that the second press is instantaneous.

Description

technical field [0001] The invention relates to a double-flush quantitative water-saving device for a toilet, which is controlled by a single button. [0002] The invention can be used in the water saving system parts of toilet tanks and storage tanks, as well as in purely mechanical mechanisms using known elements to act on water shut-off valves. Its purpose is to have two quantities of water, one less than the other, both well metered in an automatic manner, either by emptying the entire volume of liquid or by only a small volume, depending on the application. Background technique [0003] At the present stage of the art, there are various water saving devices for toilet tanks. It is especially common to have two separate floats or a pair of tanks which are controlled by a pair of buttons or handles so that depending on which handle or button is pressed the amount of water varies depending on which float or tank is used. [0004] There are also devices that have an adjus...

AI Technical Summary

Problems solved by technology

[0013] As a result, water saving depends on the will of the user, which may be affected by carelessness, negligence, forgetting, lack of knowledge or lack of comfort, whether the second push of the button is performed or whether the water saving mechanism operates correctly.

[0014] There are even flush mechanisms with a single button, where the first depression results in a partial flush, it does not depend on the impact of the water or the pressure required for the water to expel, resulting in a forced and metered water saving, but must be depressed The second time, while this must be continuous or held for a period of time sufficient to produce complete emptying of the tank, a slight momentary depression will not be sufficient for complete emptying
