Pressure-flushing system for a toilet bowl

Abstract

The invention relates to a pressure-flushing system (100) for toilet bowls, comprising a cistern mounting (500) and a drain module (200), said drain module (200) comprising a vertically oriented pressurized water tank (501) and a drain pipe (502), a hydraulic drain valve (18) and a DC pipe interrupter (5). The drain pipe (502) is mounted vertically in the pressurized water tank (501) and projects from the bottom of the pressurized water tank (201) for a flow connection with the toilet bowl. The drain module (200) is retained by the cistern mounting (500), which also carries a gas accumulator (19). The cistern mounting (500) has a water-carrying design and has a water connection (8) for connection to a drinking water mains or similar, and connecting channels (507, 510) that fluidically connect the pressurized water tank (501) and the gas accumulator. The pressure-flushing system (100) complies with standard EN 1717, is compact and easy to install. It allows pressure-wave flushing with little water and low noise emission.

Description

FIELD OF THE INVENTION[0001]The invention belongs to the field of sanitary technology and hygiene devices. It relates to a pressure flushing system for a toilet bowl and in particular to a constructive solution for a cistern mounting of the toilet pressure flushing system and to a constructive solution for an outflow module of this pressure flushing system, wherein the pressure flushing system flushes using a pressurized water wave referred to as a shockwave. The pressure flushing system is designed so that the flushing takes place with little noise development and low water consumption, wherein the avoidance of contamination of the drinking water by backflow in the event of malfunctions in the water supply system is ensured. In the documents of this application, the term “pressure flushing container” for toilet flushes is to be understood in the meaning of a sanitary fitting for toilet bowls.BACKGROUND OF THE INVENTION[0002]Pressure flushing devices are typically known in the sanit...

AI Technical Summary

Benefits of technology

The invention is a toilet pressure flushing system that includes a cistern mounting and an outflow module. The cistern mounting is designed to accommodate the pressurized water container and the gas accumulator or accumulators and connect them fixedly. The system has installation elements that can be adapted to different surroundings. The outflow module includes a pressurized water container, an outflow pipe, and a connection with hydraulic gas accumulators, which ensures a regulated flushing procedure. The system also includes a pipe interrupter to prevent the backflow of dirty water. The cistern mounting and outflow module are easy to install, operate reliably, and maintain, and they significantly reduce noise during the flushing procedure. The advantages of the system include its versatility, simple construction, and low noise development. The outflow module can be used in various toilet bowl types and is a noise reducer. The system can be fitted into a ceramic toilet bowl or existing water containers.

Problems solved by technology

These pressure flushing devices are not suitable for toilet bowls, because they are not capable without a water collection pressure device of dispensing a sufficient water quantity within a short time.

This system offers 2 L of water in three seconds, from which it is apparent that the initial water wave or the water front at the beginning of the water wave only flows out softly and does not have sufficient speed so that it is not sufficiently strong to reliably flush the toilet bowl.

One significant disadvantage of pressure flushing devices as they are described in the published American and French documents is the fact that after the valve the speed of the initial water outflow is not sufficiently rapid, i.e., the initial water front of the water outflow is not steep enough to ensure the reliability in the case of a single flush.

From a design aspect, pressure flushing devices from the prior art are characterized by:complex installation, because they consist of many structural parts, which have to be connected gradually using pipe and hose systems up to the installation location, whereby reliable installation cannot be ensured in the long term;complex service for the many fittings;risk of contaminating the drinking water in the water supply system due to backflow in the event of malfunctions;being bulky, because a comparatively large space has to be built-up.
