DUAL-DISCHARGE TANK FOR TOILETS

Abstract

The invention relates to a dual-discharge tank for toilets, including a tank, a water inlet having controlling means which are activated depending on the volume of water contained in the tank, a discharge mechanism coupled to a drainage collector, and means for actuating the discharge mechanism. The tank also includes an additional water inlet connected to a timed valve for controlling water flow, which automatically cuts off the flow of water through said inlet after a predetermined time has elapsed since the actuation thereof. The outlet of the timed valve for controlling water flow is connected to a first pipe that directs the additional water toward the drainage collector.

Claims

1. A dual-discharge tank for toilets, comprising: a tank for holding a volume of water; a water inlet having a regulator which is activated depending on the volume of water contained in the tank a discharge mechanism coupled to a drainage collector, and having a drive means; and an additional water inlet connected to a timed flow regulating valve having an output, connected to a first pipe which directs additional water from the additional water inlet into the drainage collector.

2. The tank of claim 1, wherein the first pipe is connected to a second pipe of smaller diameter, increasing an output speed of the additional water into the drainage collector.

3. The tank of claim 2, further comprising a water diffuser at a free end of the second pipe.

4. The tank of claim 2, further comprising a coupling piece connecting the first pipe to the second pipe.

5. The tank of claim 3, wherein the coupling piece is a 90° elbow.

6. The tank of claim 3, wherein the coupling piece is fixed to a lateral wall of the drainage collector.

7. The tank of claim 1, further comprising a push button located outside the tank, arranged to operate the timed flow regulating valve.

8. The tank of claim 1, further comprising an electronic detection cell located outside the tank, connected to the timed flow regulating valve such that the timed flow regulating valve is operated when a user's hand is detected by the electronic detection cell.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0015] The drawings show an illustrative FIGURE of the preferred embodiment, and are not intended to limit the scope of the invention.

[0016] FIG. 1 shows a schematic cross section of a dual flush tank according to the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0017] In view of the above stated, the present invention relates to a dual-discharge tank for flush toilets.

[0018] As shows FIG. 1, the tank comprises a tank (1), a water inlet (2) with regulating means (3) which are activated depending on the volume of water contained in the tank (1), a discharge mechanism (4) coupled to a drainage collector (5), and drive means (6) for the discharge mechanism (4).

[0019] Regulating means (3) of the water inlet (2) may be, for example, a bypass valve (3.1) operated by a float (3.2). Thus, when the water level in the tank (1) decreases, resulting from driving a discharge mechanism (4) to remove organic solid waste toilet (13), the tank (1) is emptied and the bypass valve is released (3.1), allowing the entry of water to the tank (1) until the volume of water within it regains its initial level.

[0020] In addition, the tank comprises an additional inlet for water (7) connected to a timed flow control valve (8). This connection of additional water should be used only if you want to discharge the toilet (13) for the presence of organic waste liquids.

[0021] Preferably, the timed flow regulating valve (8) is actuated by a button (12) disposed outside the tank (1). However, this could be operated by means of an electronic detection cell (not shown in the FIGURES) also disposed outside the tank (1). In the latter case, it is sufficient to bring the user's hand to said cell to operate the discharge of additional water.

[0022] Once the timed valve (8) is operated, this automatically cuts off the water flow after a predetermined time from its operation, being its output connected to a first pipe (9) which channels the additional water into the drainage collector (5).

[0023] The operating time of the timed valve (8) is defined in order to guarantee, in the discharge, the minimum water flow which completely removes the organic waste liquids from the toilet (13).

[0024] Meanwhile, it is preferred that the first pipe (9) is connected to a second pipe (10) of smaller diameter, increasing the output speed of the additional water from the drainage collector (5).

[0025] For the same purpose, additionally, the second pipe (10) may have a water diffuser (not shown in the FIGURES) at its free end.

[0026] Likewise, it is preferred that the first pipe (9) is connected to the second pipe (10) through a coupling piece (11). For example, said coupling piece (11) may be formed by a 90° elbow.

[0027] Preferably, the coupling piece (11) is fixed to the drainage collector (5) through its lateral wall (5.1).

[0028] Thus, the second connector (10) is disposed at the center of the toilet (13), which commonly goes out the discharge water.

[0029] Furthermore, it is preferred that the supplementary water inlet (7) is connected to the flow regulating valve (8) via a third pipe (14). For example, the connectors (9, 10, 14) may be formed by flexible plastic tubes.

[0030] In this way, a dual-discharge tank is provided that uses the same tank (1) as a conventional toilet tank. That is, it is not required to modify the size of the tank (1) or its internal structure—rather, it is sufficient to equip the conventional tank with a connection of additional water as described above. Thus, when the user wants to flush the toilet (13) to evacuate only waste organic liquid, limited additional water volume would discharge, and when the use wants to remove solid organic waste, it will be carry on emptying the conventional tank (1) to provide a sufficient water volume which allows to remove the organic solid waste completely from the toilet (13).
