Abstract

Improvements in water evacuation devices in high tanks. The aim of the improvements of the invention are aimed at allowing the overflow pipes to be manufactured with a larger diameter to substantially facilitate the discharge, since currently when overflows with a larger diameter are mounted, this negatively impacts the operation of the device and mainly In the download. Thus, the improvements simply consist of the incorporation of at least one additional passage or hole (10) that is located at some point of the water drop conduit that is located below the annular seat of the drill where the sealing joint supports in the closed position.

Description

Refinement in evacuation devices of water in high cisterns.

Object of the invention

The invention consists of improvements in water evacuation devices in high cisterns, essentially those used in cleaning toilets and in those tanks in which a device intervenes arrester that is generally operated by a chain or similar element.

The improvements of the invention allow the use of overflow pipes of greater diameter or section, without risk of negatively influencing the download process as it is happening conventionally when tubes are incorporated overflows of greater diameter.

Therefore, the purpose of the invention is be able to incorporate overflow tubes of larger diameter to avoid overflow problems before an evacuation flow, of said overflow tube, insufficient.

Background of the invention

Usually, the high cisterns for toilets  employ arresters in which the overflow tube has a very small diameter, so its evacuation capacity is low, which can cause overflows if you are unable to evacuate the water that emits a possible leak.

This limitation of not being able to use larger diameter overflows is due to the height of the water accumulated in the cistern makes the water velocity, during the  discharge, be very high when the overflow has little step of air, so that the ability to suck the rubber and seal ahead of time it is less than if the overflow allowed a large major air passage, in which case the discharge drill would exert a degree of suction such that it could, including swallowing the gum and overflow.

Description of the invention

To achieve the task indicated in the section of the object of the invention and in order to avoid problems indicated in the background section, the device of the invention is characterized in that the evacuation bit of the cistern incorporates an additional passage or air duct located by below the sealing rubber and also below the area of seat of that drill where the rubber supports to produce the obturation.

With this step or additional duct you suck an air flow that reduces the degree of suction produced by above the seating area of such a sealing rubber, air that initially it was channeled only through the tube overflow.

The air duct always located by under the seat of the drill where the sealing rubber rests on closed position, said duct is located or hole essentially in the threaded neck of such a drill, so that in correspondence with such a hole a partition to avoid water reflux, thus creating a Siphon species.

The thread of the neck of the brocal is interrupts to allow proper air circulation.

On the other hand, once mounted the drill, the Nuts will cover the hole so that it is hidden.

Finally it should be noted that it is possible to locate the  additional hole or passage even in the downpipe itself, yes, more effective as long as it is closer to the download area

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 1.- Shows a front view of a water evacuation device in high cisterns that incorporates the improvements of the invention.

Figure 2.- Shows a perspective view sectioned of a brocal where the improvements of the invention.

Description of the preferred embodiment

An example of embodiment of the invention according to the numbering adopted in the figures.

The evacuation device comprises in beginning a bell 1 that is fixed on a drill 2 fixed this to  turn on the bottom of a high cistern 3, peeking out and below that bottom a section or threaded neck 4 of that drill 2, threaded 4 on which a conventionally will be coupled water drop pipe 5 by means of a fitting 6 or Similary.

In turn, overflow tube 7 is coaxially coupled on bell 1, which incorporates a sealing rubber 8 which, in the closed position, rests on a highlighted annular seat 9 of that drill
2.

Starting from this described structure, the novelty of the invention focuses on providing the whole of the evacuation line of cistern 3, one step or hole additional 10 located in any case below the rubber of seal 8 and the annular seat 9 of the drill 2 where it supports the sealing rubber 8 to produce the closure.

With this air passage 10, air is sucked reduces the degree of aspiration produced above the seat annular 9 and sealing rubber 8.

In a preferred embodiment, as shown more clearly in figure 2, the air passage 10 has been practiced in the threaded neck 4 of the drill 2, at the same time as provides a partition 11 that determines an inner channel for avoid water reflux, creating a spice of siphon. He through hole 10 interrupts the thread of said neck 4 to allow proper air circulation. This interruption is extends into a groove 12 that reaches the lower edge of the threaded neck 4.

Once the drill 2 is mounted, the associated fitting 6 to the downpipe 5 cover the additional hole 10 so that it is hidden, also covering slot 12.

Claims (4)

1. Improvements in devices water evacuation in high cisterns, which include these dispositives:

-

a brocal fixed on the bottom of a cistern;

-

a bell that fits over the brocal;

-

a overflow tube associated with a sealing rubber that sits on the closing position on a highlighted annular seat that forms part of the broccoli;

-

a downward conduit connected to the cistern bit, which is also part of the section of the bit below the annular seat; characterized in that they comprise at least one additional passage or hole (10) located below the sealing rubber and below the highlighted annular seat (9), a hole that communicates the interior of the downward conduit with the exterior; all in order to reduce the degree of suction produced above the seating area (9) of the drill and sealing rubber (4).

2. Improvements in water evacuation devices in high tanks, according to claim 1, characterized in that the hole or passage (10) is located in the wall of the threaded neck (4) of the drill 2, neck that appears outside below from the bottom of the tank 3. 3. Improvements in water evacuation devices in high tanks, according to claim 2, characterized in that the through hole (10) internally flows into a channel limited by a partition (11); all in order to avoid water reflux, creating a kind of
