Abstract

A Method for emptying vessels of their liquid content and its application, among other vessels, to a toilet water tank (cistern), being characterized in that the end of the total discharge pipe, of the partial discharge pipe and of the pipe intended for the outflow of any excess liquid, said end being inside the vessel, are raised upwardly from the bottom to the top of the vessel, their open edges face the vessel top and are higher than the level (18) of liquid. The ends of the two discharge pipes inside the vessel are each inserted in a separate cup having a greater inside diameter than the outside diameter of the respective discharge pipe, said cups being of different length and having their open edges facing the bottom of the vessel. The vessel also receives the pipe supplying liquid to the vessel along with a float or other mechanism for regulating the flow of liquids and furthermore one end of each one of the two rods (4) and (7) along with their attached objects (5) and (8) of different volumes, so that when pressing or pulling the end of the said rods which is outside the vessel the respective object shall enter in the liquid and shall displace as much volume of the liquid as is necessary for the liquid level to rise until it covers the open edge of the pipe selected for discharge.

Description

A method for emptying vessels of their liquid content

DESCRIPTION

The invention relates to a method for emptying vessels of their liquid content, which method eliminates any possibility of involuntary leaking of the liquid from the vessel being emptied, given that the orifice located at the bottom of the vessel or at a vessel side near its bottom is used just for passing the common-main discharge pipe and then the orifice is completely and permanently sealed in a watertight fashion, and liquid is discharged only via the discharge pipes, inside which liquid enters from their open edges (mouths), which edges however are located higher to the vessel top than the level of liquid inside the vessel.

An application of this method is described in the case of a toilet water flush tank (cistern), this being a merely indicative application in one field and not precluding the method's application in any other field or any other use and on any other vessel. The systems primarily used presently for discharging vessels and tanks are either taps at the bottom of the vessels in question, or pumps mounted on the tanks for the pumping of liquid from the tank top.

The use of taps, however, always involves the risk of a leak, since a tap malfunction is always a possibility, and the use of pumps involves high costs to the user not only for purchasing same but for their operation as well. For the discharge of toilet flush water tanks, in particular, many different ways have so far been employed based on different methods, depending on the flush tank assemblies being used.

Toilet water tanks that have been available in the market so far can be classified under four main categories. A) Tank assemblies allowing total-only discharge.

A main characteristic thereof is that all such tank assemblies have an opening at their bottom, which opening is plugged in various ways, and usually from the base of a rod assembly seated on such opening and only when the user presses or pulls a lever is this rod lifted and the opening at the bottom of the tank opens to flush the entire content of water in the tank.

B) Tank assemblies allowing total and partial discharge.

Such tank assemblies enable the user to select between total and partial discharge. Main features of tank assemblies in category B are: a) Some of them have a pair of openings (orifices) at their bottom, which openings open and close from the bases of two separate rods and thus the water discharged during partial flush exits the tank from an opening separate than the one through which water is discharged in the case of total flush. b) The other toilet tank assemblies in category (B) have an opening at their bottom and above such opening (within the tank) they usually have an inner compartment communicating with the tank water through openings-valves, through which tank water during flushing is discharged to the inner compartment and from there, through the bottom opening, to the toilet bowl.

Toilet water tank assemblies of this category (B), and in particular of subcategory (b) comprise the tank assemblies covered under Patents US 6775859 B / 17-08-2004, US 5121510 A / 16-06-1992, EP 884423 A / 16-12-1998, DE 2556241 A / 16- 06-1977, and DE 3131706 A / 03 - 03 -1983. These specific five tank assemblies are mentioned herein because the systems used therein for flushing could be taken as identical or almost identical to our method proposed herein, if we fail to elucidate sufficiently the difference existing between those and our own proposed method. In all such patented tank assemblies, but also in all tank assemblies falling under these two categories (A) and (B), the discharge openings located at the bottom of the tank, and in the inner compartment as well, i.e. all these openings located lower to the tank bottom than the free level of the water to be discharged, open and close by plugs which, through mechanisms and rod assemblies operating in a multitude of ways, are lifted to free the respective opening achieving thus the selected partial or total discharge of the water contained in the tank, and then fall back into place in order to close tightly the tank opening.

Given, however, that scale or other foreign material, such as sand, grit, etc., deposits on the plug and on the rims of the discharge openings, the plug does not fall exactly back into place and therefore the discharge openings of the tank bottom do not close in a precise and watertight fashion.

This results in the constant leaking of water, through the said openings, into the toilet bowl with all that that such leaking implies, namely the wasting of large quantities of water and the fact that most of the times (when the amount of water leaking is greater than the amount of water entering the tank) the tank shall never be full and naturally the user shall never have a full tank permitting thorough cleaning of the toilet bowl. In comparison, the water tank discharge mechanism proposed in this invention is different and superior to all tanks of both categories (A) and (B) given that it affords two advantages, namely that the possibility of involuntary leaking of water to the toilet bowl is eliminated and that the tank remains always filled with water for use by the user. These advantages are secured by means of the following features. a) The liquid is discharged solely through openings (open pipe edges) located higher than the free level of water -as regulated by the float- within the water tank and, therefore, involuntary leaking of water into the bowl through the said openings shall never be possible. b) The opening (orifice) at the bottom or near the bottom of the vessel (tank) is used solely for passing the main-common discharge pipe and after that this opening remains at all times closed and sealed in a watertight fashion, therefore involuntary leaking through the said opening shall not be possible either. c) On the other hand, the discharge of any excess-unwanted water, resulting from float failure or other cause, through pipe 21 ensures that the free level of water is kept at the level of the open edge of pipe 21 precluding thus not only any involuntary leaking from the open edges of discharge pipes 10 and 11 which (edges) are higher to the tank top than the edge of pipe 21, but also any involuntary flushing, ensuring the ability - advantage of having the vessel (tank) always filled with water, ready to be used by the user. C) The third category of conventionally used toilet flush tank assemblies concerns tank assemblies which, for discharging, employ a pipe the one end of which, after entering the tank at its bottom, continues upwards to the tank top and when it reaches a little higher than the free level of water it turns 180 degrees so that its said end almost reaches the tank bottom and its edge as well faces the bottom of the tank. From an opening on a side brandling of the said pipe (at the pipe section which, immediately after entering the tank, extends upwards to the tank top) via a rubber ball that closes the opening and is pulled or pressed by the user (via a lever) water suction is generated through the open edge of the discharge pipe until the discharge pipe end which is within the tank fills with water at which time flushing commences and goes on until completed, aided by the atmospheric pressure exercised on the free surface of water within the tank. The following three main disadvantages of this system, as compared to the present invention, are pointed out: aa) Only total discharge is achieved by such systems.

In other words, partial flushing is not possible for short flushes such as necessary in the case of liquid waste (urine) or other when only a small amount of water is required.

In contrast, this is entirely possible with this invention. bb) If the rubber ball gets punctured or slackens or becomes otherwise damaged, it shall fail to produce the required water suction in the discharge pipe, in which case flushing shall not be possible and, therefore, the toilet flush tank assembly shall remain inactive, i.e. completely out of operation, until a qualified technician can be found for replacing the damaged ball.

On the contrary, given that the parts of the mechanism proposed for the embodiment of the present method are permanently fixed in place, they shall not be subject to any damage on account of their use and thus not only repair or replacement costs shall be saved but, more importantly, the tank shall always be filled with water for accommodating user needs. cc) One other important disadvantage of tank assemblies of this category (C) is that should a float fault occur, the water level within the tank shall continuously rise to the tank top resulting in incessant total flushes given that each time water level reaches a height at which the whole of the discharge pipe is covered therefore is filled with water, tank discharging shall automatically be initiated. Such continuous flushes, however, shall result in wasting large amounts of water given that the float shall operate continuously in the full open position and furthermore the user many times shall find the water tank empty and shall be required to wait for the tank to fill before flushing.

In the method proposed herein, however, given that any excess water shall be discharged through the third pipe 21, intended for this purpose, the free level of water within the tank shall always be kept at the level of the edge of said pipe avoiding any involuntary flushing.

Therefore, in the case of float failure as well, this invention presents an advantage over the above methods, as follows: a) The tank shall always be ready (full) for use by the user, and b) Water loss shall be significantly reduced, given that minimal amount shall leak, i.e. the amount leaking from the float which shall be commensurate with the extent of the damage rather than having its edge completely open. D) The fourth category of toilet flush tank assemblies comprises the total-only discharge tank assembly used in older times; this was characterized by a discharge pipe mounted on the tank bottom, and from there its one end exited from the tank bottom and from there reached the toilet bowl, and its other end was raised upwards within the tank and reached higher than the water level inside the tank. The entire pipe section within the tank entered an inverted cup with the open edge of the cup reaching the tank bottom, and the cup having widened rim at its open edge. When the said cup was raised with the assistance of a rod and was then released and the cup rim reached once more the water tanlc bottom, water started to flow until complete discharge of the tank. This had the following disadvantages compared to our method. Aa) There was no provision for partial discharge for short flushes such as necessary in the case of liquid waste (urine) or other when only a small amount of water is required.

In contrast, this is entirely possible with this invention. Bb) The lever that the user would pull and which in turn would draw, towards the tank top, the inverted cup within the discharge pipe end located within the tanlc for starting a flush, was attached to a mechanism which was seated on grooves of the upper end (opening) of the tanlc without any other support and thus, the said lever and mechanism would often shift position and would be unable to operate unless the fault were first repaired (repositioning of the mechanism and lever-cup on the relevant grooves), which would involve quite strenuous and, for many users, difficult repair work. In comparison, in the method presented herein the cups on the discharge pipes' edges and all other parts shall remain fixed in position and only the free level of water shall rise to initiate a flush and, therefore, there shall never be a need to repair and no operation failure of the tank assembly shall ever occur. The discharge of toilet flush water tanks, as an application of the method presented herein, shall be effected through a mechanism comprising two discharge pipes, another outflow pipe for any water excess (formed as a result of float failure or other cause), and two rods which, on the user's option, the rod selected each time shall be pressed or pulled by the user in order to immerse an object (ball) in the tank water. Such object, once immersed in the water, shall displace a water volume equal to its own volume and the said volume shall be such as necessary for raising the water level within the tank to a height in which the open mouth (edge) of the discharge pipe selected by the user shall be covered with water and at the same time the inverted cup at the end of the said pipe shall also fill, for initiating the selected partial or total discharge. The rods immersing the said objects in the tank water, which rods elevate the free level of water, can also -if so desired- be connected to the toilet flush-button, and the objects (balls) may be limited to a single but bulkier object and moreover the said object may also be used for regulating float operation.

In such case, when the button is pressed at its one edge or its other side, a lever or rod connected to it shall immerse in the tank water at times the entire object and at times a part thereof, for achieving at times partial and at times total discharge of the water vessel (tank).

The discharge of only part of the water volume contained in the vessel shall be effected through one of the discharge pipes, while the other pipe shall accommodate total discharge of the water contained in the vessel, at the user's option. The third pipe to be located in the vessel as per the method proposed herein shall drain to the bowl any excess-unwanted water being discharged into the tank as a result of float failure or other cause avoiding thus the involuntary elevation of the water level in the tank above the specified desired height. The toilet flush water tank and the mechanism in it as proposed in the present invention, is characterized by the fact that it shall be possible to optionally join one end of each of the two discharge pipes and of the outflow pipe into one common pipe within the tank near the tank bottom, the said common pipe shall exit from an orifice at tlie tank bottom or an orifice at a side of the tank, the said orifice of the vessel shall then be sealed in a watertight fashion and the common pipe shall extend into the toilet bowl. An appropriate groove (opening-orifice at a pipe side branching that shall be sealed . in a completely watertight fashion) on the said common pipe shall accommodate a deodorizer, a small amount of which shall be carried along and be discharged along with water in every flush.

The other three ends of the pipes located within the vessel shall extend upwards until the open edges of the said ends (of the partial and total discharge pipes and of the pipe used for the outflow of any excess water being discharged into the tank as a result of float failure) reach higher to the vessel top than the free level of water within the vessel and the said open edges shall face the vessel top (roof). Of the three open ends of the three pipes located within the water vessel, the edge of the total discharge pipe end shall have been raised upwardly to the vessel top a little higher than the level to which the edges of the ends of the two other pipes shall have been raised, the edge of the partial discharge pipe shall in turn have been raised a little higher than the level to which the edge of the outflow pipe for any excess water (any water flowing in the vessel as a result of float failure or other cause) shall have been raised, and the edge of the excess water overflow pipe shall have been raised slightly higher than the free level of water within the vessel.

Furthermore, each of the two open edges of the two discharge pipes (for partial and total discharge) shall enter a separate cup each, each said cup having an inside perimeter considerably wider (of a wider diameter) than the outside perimeter (diameter) of the discharge pipes. The said cups shall be of unequal lengths and the open mouths (edges) of the said two cups shall face the bottom of the vessel. Said cups shall also receive, in addition to the open edges, a section of the discharge pipes as well. In particular, almost the entire section of the total discharge pipe which (section) is within the water vessel shall enter the respective cup (the longer one), and part only of the partial discharge pipe section which is in the water vessel shall enter in its respective cup (the shorter one). Thus, due to the unequal length of the cups, the open edge of the cup at the end of the total discharge pipe shall reach almost to the bottom of the water vessel, while the open edge of the cup at the end of the partial discharge pipe shall reach as lower to the bottom of the water tank than the free level of water in the vessel as shall be considered necessary so that the amount of water contained in the vessel in question in each specific application from such point and up to the water level be sufficient for short flushes such as necessary in the case of liquid waste (urine) or other when only a small amount of water is required.

The inside perimeter of each one of these two cups shall be such so that, between the inner surface of each cup and the outside surface of the corresponding discharge pipe in the perimeter of the discharge pipe and over the entire length of the pipe section located within the cup, a ring-shaped empty space be formed, preferably uniform, and the same empty space shall also exist between the open edges of the discharge pipes and the bottom of the respective cup.

A small gap shall also exist between the bottom of the water vessel and the open edge of the cup at the end of the total discharge pipe so that, following total discharge, a small amount of water remain within the vessel along with any particle such as dust, grit and other foreign material. hi the water vessel proposed to be discharged under the method described in this invention, there shall also be the following two fittings in addition to the two discharge pipes and the excess water outflow pipe. a) The water tank shall receive the pipe supplying water to it, and at the end of the said pipe, within the tank, the float or other mechanism shall be attached for automatic regulation and cutting-off of the liquid flow; the said float shall stop the flow of water to the tank when the water level within the tank rises to the predefined desired level (height) and naturally, as per the present invention, such height shall be a little lower to the tank bottom than, the height of the open edges of the discharge pipes and of the outflow pipe for excess-unwanted water (as a result of float failure or other cause), otherwise there shall be incessant leaking of water into the bowl through the outflow pipe, b) Two rods, with a section of each one extending, in a multitude of ways, inside the tank and at any rate so that one end of each rod shall be outside the water tank, and the other end of each such rod shall be inside the tank and in particular a little higher to the tank top than the water level inside the tank. c) To each one of these rod ends, inside the tank, an object shall be attached, with the said two objects having different volumes.

When the end of the said rods which is outside the tank is pressed or pulled, then the object attached to the other end of the said rod shall enter in the tank water. Then, of course, an amount of water shall be displaced of a volume equal to the volume of the immersed object and naturally the water level inside the tank shall rise accordingly. The volume of the immersed objects shall be such as required in order for the water level inside the tank to rise up to the point where the entire selected discharge pipe shall be completely covered, i.e. up to the point where the open edge of the discharge pipe selected by the user is covered and the cup attached to the end of the selected discharge pipe be filled with water.

For achieving partial only discharge of the tank, the smaller object must be immersed in the tank water in order thus to cover the edge of the pipe that discharges only a small amount of water, with the open edge of the said discharge pipe being, as per this invention, lower to the tank bottom than the level of the open edge of the other discharge pipe that accommodates full (total) emptying of the tank. Therefore, for partially emptying the tank the rod to which the smaller object is attached shall be pressed or pulled and the discharge shall stop as soon as water level falls so that the open edge of the cup of the said pipe is outside of the water. Conversely, for full emptying (total discharge) of the tank, the rod to which the bulkier object is attached shall be pressed or pulled, given that the open edge of the total discharge pipe is higher to the tank top than both the height of the open edge of the partial discharge pipe and the height of the water level inside the tank and, therefore, water level must be further raised in order both to cover the open edge of the total discharge pipe and to fill the respective cup with water. When the open edge of the partial or total discharge pipe shall have been covered with water and the respective cup shall have been filled with water, the emptying of the tank shall commence and shall last, due to the atmospheric pressure exercised on the surface of the water inside the tank, until the water level inside the tank drops so that the open edge of the cup through which discharge is effected is above (out of) the water. Given that the amount of water discharged into the bowl shall be more than the respective amount of water that the float shall allow to flow into the tank, the water level shall continue to drop from the tank top to the bottom until total or partial discharge is complete, as a result of the atmospheric pressure exercised on the surface of the water inside the tank.

It is also stressed that when total discharge is sought and therefore the user must press the rod that shall immerse into the tank water the builder object, attached to the said rod, and/or both objects if both rods are pressed, the water level shall rise so that the edges of both discharge pipes but also of the outflow pipe shall be covered. As a result, discharge shall initially be through all three pipes and immediately thereafter only through the two discharge pipes. Of course, when the water level drops to a level in which the edge of the cup at the end of the partial discharge pipe is out of the water, discharge shall continue but only through the total discharge pipe.

The present invention can find its practical application in a multitude of ways.
