Abstract

Domestic water reuse system semi-residual in the toilet cistern.

The system, whose purpose is to achieve an important
Drinking water savings, is based on concentrating the wastewater from appliances (1) such as sink, shower, bidet and others, in a siphoning canister (3) hydraulically connected to a pump (11) that through a conduit ( 12) supplies the wastewater to a hidden tank (20) from which the toilet tank (32) is fed through a duct (31), a cistern that also has an access (38), this one for clean or potable water, controlled as the conduit (31) by respective buoys (34 and 42), the latter assisted by a retarder (44) so that the entry of drinking water only acts in the absence of semi-residual water in the deposit (20).

Description

Domestic water reuse system semi-residual in the toilet cistern.

Object of the invention

The present invention relates to a system domestic water reuse semi-residuals that originate in a dwelling, to feed the toilet cistern. It is based on a series of mechanisms that collect wastewater from of the daily activities of the house, storing them in a hidden tank and reusing them for feeding the toilet cistern. The system has means for double filling the tank, also with drinking water, in case of lack of semi-residual water, which guarantees the cistern service at all times. The system brings with it a considerable saving of drinking water.

Background of the invention

The inventor is unaware of the existence of any system that takes advantage of semi-wastewater Domestic It is understood as semi-wastewater the water coming from the bathrooms of the houses, specifically the sink, bidet, shower or bathtub, as well as the washing machine and any other source of drinking water consumption. The semi-residual water generated by these elements It is mixed with abundant cleaning products, fundamentally soaps, which with a debugging system are eliminated directly to the drain.

Waters with a water high in fats and oils, such as those from sink, dishwasher, etc.

The water that is currently expelled from the toilet tank is suitable for human consumption, that is to say it deals with drinking water, which could be used for drinking and that you are using for an end that does not require such a need, which causes excessive drinking water consumption. Specifically the drinking water expense by the cistern that is expelled by the toilet normally in the house it can overcome, according to the number of people who inhabit it and the frequency of use, the 100 liters of  Water.

Description of the invention

The domestic water reuse system semi-residual in the toilet cistern, which the invention proposes, resolves in a fully satisfactory manner the problem described above, allowing reuse waters and, consequently, drastically reduce the consumption of drinking water.

For this and more specifically the system part of the use of a modified siphonic boat, in which the pipes or pipes belonging to the semi-wastewater generating elements cited, such as bidet, shower, bathtub drains, washing machine, etc., counting said siphonic boat with an overflow connected to the general sewage disposal network, and with an outlet substantially below said overflow, connected to a pump and through the latter connected in turn to the hidden deposit.

A level sensor, buoy type, set in the siphon boat, starts a pump every time the water level in the siphon boat exceeds a value preset

The hidden deposit, preferably located between the roof of the passenger compartment and the plaster or false ceiling of the It also incorporates an overflow through which it communicates with the general sewage disposal network, and another sensor buoy level, so that when the water level within said deposit exceeds the preset maximum value, this level sensor interrupts the operation of the pump it assists to the siphon boat, losing excess water semi-residual through the overflow of said boat siphonic

From this hidden deposit and through a proper driving feeds the toilet cistern, by The classic level buoy system.

In order to ensure proper functioning of said cistern, even in the absence of water semi-residual, said tank is powered by two ways, one the already mentioned semi-residual water and another of drinking water, which will act only in the absence of water semi-residual and that is also assisted by a level buoy, which works in collaboration with a device retarder, so that the drinking water supply only It occurs when, after the discharge of the tank, a predetermined time without filling of the same.

Preferred Embodiment of the Invention

In the general scheme of the installation, shown in figure 6, have been referenced with (1) the different water generating elements semi-residual, such as sink, shower, bidet, etc, which drain through respective pipes (2) towards a siphonic boat (3), which appears schematically detailed in the Figure 1.

This siphon boat (3) has tickets (4) for the different and mentioned pipes (2), inlets (4) that can be even in greater number than the access pipe (2), in in which case there are plugs (5) on the remaining entries.

In any case the siphonic boat (3) counts with an overflow (6) associated with a top outlet (7) connectable to the general drain of the house, also having another exit lower (8), at a significantly lower level, provided with a filter (9) and that through a pipe (10) connects hydraulically with a pump (11) provided with the corresponding conduction (12), shown in detail in Figure 3.

The said pump (11) is put into operation with the contest of a level sensor (13) that closes the circuit supply (14) of the pump (11) when a buoy (15) housed in the siphon boat (3) and through its lever (16) tilting on an axis (17), acts on the piston (18) of the own sensor, as shown in figure 1, where the existence of a cable gland (19) that assists the lever (16) to its exit of the siphonic boat (3), ensuring the tightness.

The outlet pipe (12) of the pump (11) is starts in the upper area of a hidden deposit (20) located by above the level of the cistern, preferably located between the roof (21) of the passenger compartment and the false ceiling (22) thereof, by example of plaster, with fixings (23) to said ceiling (twenty-one).

This deposit (20) has a spillway (24), which controls the maximum level (25) of water in said tank that may exist in it, but also in said deposit (20) a second level sensor (26) with its corresponding floats (27) and bar (28), controlling this pump level sensor (11) and preventing it from being put in operation, even when there is water in the siphoning boat (3), when the hidden tank (20) is full.

A side plug (29) allows access to the inside the tank (20) in maintenance, deposit in whose bottom is established the exit hole (30) and the corresponding conduit (31) for communication with the cistern (32) of the toilet (33).

Water inlet to the cistern (32) through of the duct (31), is carried out in collaboration with a valve level provided with a second buoy (34) whose base (35) scales on a second axis (36) and acts on a shutter (37) that opens or close the water inlet, as is conventional.

As previously stated, the cistern (32) has the peculiarity of having a double system of food, on the one hand the one corresponding to water semi-residual, already described, and on the other hand a access (38) of clean water, ie drinking water, which is used exclusively in emergency situations, that is in absence of semi-residual water in the tank (20). For this, the access (38) is assisted by a valve (39) associated with a lever (40) which in turn and through an arm (41) is associated with a third buoy (42), being such a lever (40) tilting through an axis (43) established in its middle zone, and incorporating a container (44) in contrast to its valve (39),  preferably plastic, equipped with a top level plurality of holes (45) that ensure rapid filling with water from it, and in its lower area a small hole (46) that in turn determines a slow emptying. When the cistern is full the third buoy (42) causes the valve (39) to remain closed. When the discharge of the cistern occurs through the corresponding mechanism, not represented in the drawings, the lack of water thrust for the second and third buoys (34) and (42) makes  First, the water inlet shutter (37) opens semi-residual with the consequent filling of the tank up to the maximum level (47) of the same provided for that purpose, keeping the clean water valve (39) closed by effect of the weight of the container (44) with its water content, so that the filling of the tank, under normal conditions, occurs always through the conduit (31) corresponding to the water semi-residual However in the absence of this water semi-residual, the cistern (32) remains empty, the container (44) is slowly emptying through the small hole (46), until it is completely empty, at which time the clean water pressure of the access (38) overcomes the valve (39) taking place the valve opening, until the limit situation of filling the tank, in which said valve (39) returns to the closing situation due to the upward thrust on the third buoy (42).
