DE2915581A1 - Toilet flushing cistern water saving system - has press knobs and outflow valves providing continuous discharge volume adjustment - Google Patents

Abstract

In an economy system applicable to any water closet, discharge of water can be affected by operation of buttons, and opening and closing of outflow valves, providing different selected max. and min. volumes. Discharge can be continuously regulated, according to needs. There are pref. three buttons, and two outflow valves, one above the other, with float for each, and pref. with an intervening partition in the cistern. Valves and lid may be easily fitted to an existing installation, without skilled labour. This combines adequate hygiene with water saving.

Title: Toilet cistern with water-saving system Field of application: The invention relates to a toilet cistern with a water-saving system for use on every toilet Purpose: For flushing, cisterns are used in case of insufficient water pressure to accumulate enough water for flushing to ensure adequate flushing and at the same time to achieve maximum hygiene with the specified amount of water.

State of the art: toilets are flushed using cistern flushing systems or by water pressure directly from the water connection. The requirements for douching with a direct water connection are often not available due to the lack of water pressure. Wherever they are, 1. there is usually a noise nuisance, 2. it is Hygiene is not guaranteed in the event of insufficient use, as faecal residues are often due to too low water emissions remain and 3. water pressure systems are very susceptible to repair. Where the water pressure is insufficient, cisterns are used to store water used. Toilet cistern flushing systems all work with a minimum amount of water of approx. 10 1.

The amount of water of approx. 10 1 is fully poured out with each rinse.

Criticism of the state of the art: The cistern flushing systems currently in use do not allow variable water output. A maximum of 10 1 water output will be ultimately only required for flushing away coarse faeces, whereas smaller ones are sufficient Amounts of water when disposing of liquid feces only and when disposing of them hygienically harmless small waste an even smaller amount of water.

The conventional cistern flushing systems are therefore unnecessary Water and money wasted.

Task: The invention is based on the task of a cistern flushing system to create that both hygienic requirements and water-saving opportunities is fair.

Solution: This object is achieved according to the invention in that the WC cistern is equipped with a water saving system.

The required water output can be set using three operating buttons from the cistern to the toilet bowl: when you press the economy button (A) Depending on the coordination with the toilet facility, a water distribution of 3 up to 5 1, which is sufficient to dispose of liquid faeces hygienically.

Pressing the full flush button (B) empties the entire Cistern of approx. 10 1 water filling for the hygienic disposal of coarse faeces.

With the stop button (C) the rinsing process can be started, either by means of Button (A) or (B) has been triggered, stop so that the water expulsion is on any Quantity - less than 10 1 - can be limited.

With button (A) the outlet valve 1 (V1) is opened by lever action. With button (B) the outlet valve 2 (V2) is opened by lever action. (V1) and (V2) are through bushings (LE1) and (LB2) and brackets (4 x (BH) and 4 x (H)) arranged one above the other, with (V1) lying above (V2). (You can also do this side by side if they are separated by a wall).

Both (V1) and (V2) are each side with a small float (S1) and (S2), which keep the valves open until the water level drops the float allows it to fall and the valves can close.

The liner 1 (LB1) with float 1 (S1) is at the height of the Bracket (H) adjustable with clamping rings (K) so that the float controls the amount of water flowing out by its set height and by the corresponding one preventing the valve from falling Knob (N) limited to approx. 5, 4 or 5 1 depending on the cistern dimensions.

The water output from (V2) takes place directly into the inflow to the toilet bowl sel, the water output from (V1) during economy flushing goes through the pipe from (V2) into the Toilet bowl inflow. (V2) remains closed.

The outlet valves are each provided with fflit seals (Dl and D2).

When the stop button (C) is pressed, float 1 (S1 from V1) is through pushed down a rod so that (V1) can close. Under (S1) is one Pole attached, which transfers the pressure from (C) to float 2 (S2 from V2), so that the water outlet from (V1) as well as from (V2) is stopped by button (C) can be. A pressure spring (F) releases the float immediately after releasing (C) free again.

Another embodiment of the invention: The brackets of the whole The valve system of the toilet cistern with M water-saving system are on the cistern floor Assembled easily interchangeable and with variable assemblies, so that already used cisterns can be converted without the assistance of specialists.

The lid of the cistern with the buttons is designed in such a way that it that with used cisterns a retrofitting is also problem-free. The conversion with the valve system and the cistern lid with buttons and associated levers thus enables the economy system to be used cost-effectively in every toilet without one having to purchase a complete cistern.

Achievable Advantages: The advantages associated with the invention exist in particular that the amount of water used for flushing (usually drinking water) can be reduced by at least 50% without sacrificing hygiene requirements to have to.

In addition to the environmental need to save water the cost of flushing the toilet is reduced by at least 50%, so that the minor Additional acquisition costs in a 2-person household amortized after just one year will have.

The conversion of used cisterns improves the costing still considerable.

The invention thus becomes an urgent need today just.

Description of an exemplary embodiment: An exemplary embodiment of the Invention (the valve system arranged one above the other) is shown in drawings and is described in more detail below. 1 shows the cistern lid of at the top with the buttons: economy button (A), full flush button (B) and stop button (C).

Fig. 2 the function of the keys (A, B and C).

Pressing the economy button (A; lifts valve 1 (V1) with seal 1 (D1) inside liner 1 CLB1). The float 1 (S1) only leaves the valve again close when the desired water output is reached or when it has passed through the Stop button (C) is depressed.

When the full flush button (B) is triggered, the same systematic action occurs Process at (V2), but with a water output of approx. 10 1, if it does not go through (C) is stopped. (V1) is lifted with (V2).

In both cases, the water drains through the outlet (AB) in the toilet bowl.

The floats (S1 and S2) released immediately after releasing (C).

Fig. 3 the approximately required dimensions of the valve system in order to Outlet for the first 5 to 5 1 to maintain sufficient flushing pressure.

Economy button (A), full flush button (B), stop button (C), seals (Dl and D2), brackets (H) of liner 1 (LB1) with float 1 (S1), floor brackets (BH) of liner 2 (LB2) with float 2 (S2), cistern floor (SB), clamping rings (K) and knobs on the valves (N).
