DE19826188A1 - Two-chamber toilet flushing system - Google Patents

Abstract

The first chamber (I) is smaller in volume than the second chamber (II) thus offering both small and large volume flushing. The two chambers are divided by a partition wall and both have separate cisterns with shared water feed but with separate floats and separate shut-off plugs so that they can be used separately. The two plugs are necessarily of different size appropriate to the respective water volumes and enable the chambers to be used individually as required, though both water volumes share a common outlet pipe issuing into the toilet. Two keys are provided at the same level but of different size, using the large key for the large volume and the small for the small volume. The keys can be used separately. One possibility is to use the smaller chamber for cleaning or hygienic purposes, bringing in hot water along a separate line.

Description

The principle is that contrary to conventional toilet cisterns instead of two water storage chambers are available, with different buttons for the small and large chamber available for Ver (see. Fig. 1 to 3). The buttons can be pressed as required, whether large or small business or intermediate rinses. See claim 1.

The buttons can be arranged on the left or right together ( Fig. 1, Fig. 3) and either a flush button on the left or right. According to this arrangement, the water supply or the float arrangement can be selected accordingly. The known technical solutions will be used there.

In order to enable the separate drainage of the water storage chambers, a sealing plug must be provided for each storage chamber ( Fig. 1 to Fig. 3), which with the above. Flush buttons allow water to flow.

Since for the cistern a chamber partition ( Fig. 2 Detail A) is a prerequisite for the formation of the two separate pantries, this must be maintained up to the two-walled outlet connection (see claim 2) - Fig. 4 Detail A - the respective sealing plug after actuation of the flush buttons ( Fig. 1 detail A) introduces the water into a common short drain pipe and opens into the toilet.

The size of the chambers is determined as necessary and depends on the Water supply requirements. Furthermore, the well-known water regulation via saving branches and Float setting possible.

The application of the above. The principle of the two water storage chambers is equally suitable for front and rear wall mounting. It should be noted that the flush button ( Fig. 5) for large and small flushing must be actuated separately for rear wall mounting. That is, instead of the known one, a large and a small key are arranged side by side (see claim 3).

The following advantages are seen compared to the conventional cistern (one chamber):

• 1. Further water reduction, that means cost savings for the individual and the ecological Effect for the community.
• 2. Very child-friendly activity with the effect of promoting awareness to save water totality.
• 3. The convenience of using the economy buttons is counteracted.
• 4. It is a particularly high water reduction in public buildings and sites with large Public traffic expected.
• 5. Optical refreshment compared to conventional cisterns by key combination, i.e. 2 keys left or 2 keys right or key left and right ( Fig. 1 to Fig. 3).

The keys can be contrasted in color or differentiated with g large and k = small.  

The operation of the two-chamber toilet cistern can also be useful in other ways. The second smaller chamber (size as required) could alternatively also be used as a cleaning chamber (see FIG. 3). By supplying warm water through a second separate pipe (can be done continuously or discontinuously by water regulation), as well as by adding detergents in a separate compartment as required (see Fig. 3 Detail A), an extraordinarily large hygienic effect is achieved during use (e.g. For example with greasy residues etc.).

The release of heat would be a useful side effect.

The feeling of cleanliness would be further increased and thus the development of humanity Be taken into account.

In general:

• 1. Known solutions can be used for the technical implementation, albeit in a modified form.
• 2. The presumably higher production costs and the resulting higher retail prices are quickly amortized by the water savings.
• 3. The system will initially be at the higher standard.

Claims (3)

1. Two-chamber toilet cistern, which is used in the sanitary area, is characterized in that

• a. that there are two separate water storage chambers, one with a small volume and the second storage chamber with a large volume for small and large flushes.
• b. that both chambers are separated from each other by a partition.
• c. that both chambers have separate flush buttons with shared water supply, but with separate floats and separate plugs, which enable the separate use of the water storage chambers.

2. Two-walled outlet nozzle according to claim 1 is characterized in

• a. the two plugs, which inevitably have a different size due to the different size of the water storage chambers, only allow the separate use of the chambers to become technically effective.
• b. the water from the small and large chamber flows separately into the subsequent common drain pipe, which opens into the toilet

3. Two-part flush button of the rear wall assembly for small and large flushing according to claim I is characterized in that

• a. that two buttons with different widths but the same height are arranged side by side
• b. that the wider button is used for large flushing and the smaller button for small flushing.
• c. that both buttons can be used separately.
