Description

Explanation Protection Claim 1

in the Water tank conventional Type of water is stored, which in the flushing process by the gradient to down into the sanitary ware, in the toilet, the urinal or similar flows. This assumes that the water box is above the toilet. He is either embedded in the wall or, where this is not possible, too expensive or too expensive, he is in front of the wall or directly on attached to the toilet. However, these visible solutions will be happy avoided for aesthetic reasons.

in the Contrast needed the invention no gradient between water tank and toilet. It is possible to lower the water box or at the same height to install with the toilet. The "water box" may e.g. in the sanitary Ware be housed, he could also be behind the toilet or under the sink, which often in the immediate vicinity of the sanitary ware is appropriate. Thus, the water tank shown here is a favorable Alternative to the flush-mounted installation, which can also be used in problematic situations (thin walls, reinforced concrete walls, old and weak walls) installed without effort (renovation of old bathrooms in rental apartments) can be.

The Construction starts from a water tank ", which neither have rigid walls must, one more must have typical box shape.

• – z.B. jegliche Art elektrisch betriebener Pumpen
• – z.B. mechanische Vorrichtungen, die nicht nur Wasser, sondern auch Druck speichern (Wasserdurck des Frischwasserleitungssystems speichern um ihn beim Spülvorgang zur Beförderung des Wassers in die Toilettenschüssel zu nutzen). z.B. Balge, die unter Druck gehalten werden; Blasen oder Ballons aus Gummi, die sich dehnen wenn das Wasser einströmt; Zylinder in den beim einströmen von Wasser ein Kolben gegen eine Feder gedrückt wird.
• – z.B. mechanische Vorrichtungen, die den Druck des Frischwasserleitungssystems direkt nutzt um das gespeicherte Wasser zu Befördern
• – z.B. mechanische Vorrichtungen, die andere Kräfte nutzen um das gespeicherte Wasser in die Sanitärkeramik zu befördern. (z.B. Pedal, ...)

In the invention, the transport of the water in the toilet is done by a kind of pump. A pump in this sense is any device that applies pressure to deliver water from the water box into the cling

• - For example, any kind of electrically operated pumps
• - eg mechanical devices that store not only water but also pressure (store the water drain of the fresh water piping system for use in the flushing process to carry the water into the toilet bowl). eg bellows which are kept under pressure; Rubber bubbles or balloons that stretch when the water flows in; Cylinder in which, when water flows in, a piston is pressed against a spring.
• - For example, mechanical devices that uses the pressure of the fresh water system directly to transport the stored water
• - For example, mechanical devices that use other forces to promote the stored water in the sanitary ware. (eg pedal, ...)

Declaration of protection claim 2

• – der Montageaufwand ist größer,
• – bei elektrischem Strom wären zusätzliche Sicherheitsvorschriften zu beachten.

The invention described here is based on the problem that connecting the water box to an additional power supply brings disadvantages.

• - the assembly effort is greater,
• - Electricity would require additional safety regulations.

The The invention described herein is a water box suitable for this purpose is not only to store water, but also pressure.

The Operation is the following: Through the supply of the water box (E) flows at first slowly Water from the network of water supply. So slow now Water flows into the water box, so slowly the pressure can be built up, which is necessary to the contents of the water box during the flushing process in the toilet bowl (at A) to catapult. The advantage is that the line pressure of the supply line is generally many times higher than the pressure of the for the Pump (P) required becomes.

• – daß eine Blase dicker wird (wie ein Luftballon),
• – daß sich eine Feder staucht während sich ein Balg dagegen drückt,
• – daß sich ein Gasförmiges Medium komprimiert,
• – daß sich ein weiches Material (Gummi/Schaumstoff...) komprimiert,
• – daß ein Gewicht nach oben gedrückt wird
• – usw.

The pressure storage (at the same pump) is done by a usual, suitable principle such as,

• - that a bubble gets thicker (like a balloon),
• - that a spring bends while a bellows presses against it,
• That a gaseous medium is compressed,
• - that a soft material (rubber / foam ...) compresses,
• - That a weight is pushed up
• - etc.

The Element of water storage and the element of pressure storage can be the same (as in the drawing II and III), but it can be also act on two elements (e.g., in a bellows becomes air Compressed during the flushing process pressed into the water tank), which in some way with each other are connected (water, air hose, pipe, lever, rod, etc. )

principle Zeichnungn II and III

at the example in drawing II becomes the water reservoir (cylinder) kept under pressure. This is done by a spring acting on a piston presses (area P).

at the example in drawing III holds a balloon (P) the water under pressure.

The invention described here is based on the problem that drinking water is subject to certain purity regulations, which prescribe a "free outlet" in many states. For this to work, there is atmospheric pressure (usually) in the area of the "free outlet". In the invention described here, the hydropower is transferred before the free outlet in a different form of energy. The energy thus converted is used to run one or more pumps again after the "free outlet". An energy storage device stores the energy between the time when it starts up and when it empties out of the water box. The components that could do this would be, for example

• - Turbine for energy, battery for energy storage, piston pump or similar. for pressure generation
• - Steam machine principle (instead of steam fresh water) for converting the water power into kinetic energy, power transmission with connecting rods, piston pump for converting the kinetic energy into water pressure, energy storage as described in protection claim 2,
• - Principle of the gear pump (reverse system) or centrifugal pump (reverse system) for obtaining rotational energy, shafts for power transmission, gear pump or centrifugal pump for pressure generation, energy storage as described in protection claim 2 or by spring or springs on the two-part wave,

Corresponding Of the components that are used it is certainly advisable to go through Valve, which is driven by a float is a flood to exclude the water storage (if the component T does not fulfill this task)

In In the drawing, the line (k) represents the power transmission.

Declaration claim for protection 4

Of the Invention is based on the problem that an appliance for households preferably Should be maintenance free. In addition, it is advantageous if they are small is (mounting dimensions) and manages with few components (costs).

This is solved in the invention in such a way that the component T (conversion of hydropower in a torque) the torque directly to the Pump (P1) passes. Between T and P1 is the "free outlet" at atmospheric (not necessarily) Print.

He is certainly an advantage if P1 pumps a little more water than T for the extraction of the torque needed. This is possible, since the pressure of the drinking water pipeline system is greater anyway as the one who needs is to push the water into the toilet or urinal. in the Area of "free Spout "could too be a float, which interrupts the supply at too high a water level. Between this apparatus (b) and the downstream apparatus (a) can a valve (depending on the nature of the pump, this is superfluous), which allows the flow of water in one direction only.

The Downstream apparatus (a) connects the water tank with the Energy storage (simultaneously 2nd pump (P2)) and the valve which at flushing open becomes (VA).

component T could a gear pump (reverse principle), centrifugal pump (reverse principle), a turbine, a component with rotary pistons, with cylinders and connecting rods who transferred to a wheel be (steam engine principle) or any other type of component which is suitable for converting water energy into rotational energy.

component P could be corresponding to any type of pump, the rotational energy in hydropower (pressure) converts. For example, a gear pump, a centrifugal pump a piston pump with a connecting rod driven by a wheel, a pump with a rotary piston ...

Statement of protection claim 5

Of the Invention is based on the problem that an appliance for households preferably Should be maintenance free. In addition, it is advantageous if they are small is (mounting dimensions) and manages with few components (costs).

This is solved in the invention in such a way that the component T (conversion from hydropower into a kinetic energy) the kinetic energy directly (over strands (d)) to the pump (P1). Between T and P1 is the "free outlet" at atmospheric (not necessarily) Print.

It is certainly an advantage if P1 pumps a little more water than T for the extraction the kinetic energy needed. in the area of "free run" could also be a float, which interrupts the supply at too high a water level. Between this apparatus (e) and the downstream equipment (a) can a valve (depending on the nature of the pump, this is unnecessary), which allows the flow of water in one direction only.

The downstream apparatus (a) connects the water storage with the energy storage (at the same time 2nd pump (P2)) and the valve which is opened during the flushing process (VA).

Declaration of protection claim 6

in the Protection claim 6, a "free outlet" is guaranteed, but is pumped only after the water tank. Before the "free outlet" is water power converted into mechanical energy, by a suitable for this purpose Component (centrifugal pump (reverse principle), gear pump (inverted) Principle), steam engine (instead of steam water), ...). This energy (In the drawing, a torque transmitted through a shaft (m) will) be with one for it suitable component mechanically stored (S). In this Drawing this is done by a spring that is pulling up. It could but also be a compression spring which is compressed by a spindle, a weight being lifted or a medium being compressed ... In the flushing process drives the stored energy to a pump (e.g. Gear pump, piston pump ...). In the drawing, the point indicates f the point at which the shaft is prevented from rotating, or a rinse triggered becomes. The trigger the rinsing process However, depending on the design of the energy storage or the pump, too take place there. It may make sense to place a valve before the "free outlet" which is controlled by a swimmer to overflow to exclude the water storage.
