Definitions

  • the invention relates to a device for pressure flushing a toilet bowl, with a safety device which prevents contaminated liquid from flowing back out of the toilet bowl as a result of back pressure and/or suction into a drinking water installation, the safety device having an air inlet opening.
  • the invention relates to a toilet bowl with a device of the type mentioned above for pressure flushing a toilet bowl, as well as the use of such a device in combination with a toilet bowl.
  • Toilets have long been known that include a container called a cistern or water tank, in which water is stored, which is drained into the toilet bowl as flushing water when the user presses a button or lever that initiates the flushing process the toilet triggers.
  • the cisterns of such toilets are usually arranged elevated in relation to the upper edge of the toilet bowl. This position allows gravity to be used to direct water into the toilet bowl.
  • High-hanging cisterns with float valves were already used in toilets in the last century. Because of the relatively loud noise of the flush and the unsatisfactory appearance, these high-hanging cisterns are rarely used today.
  • low-hanging cisterns, cisterns placed on the toilet bowl or, preferably, wall-mounted cisterns are used instead. The latter are also known as concealed cisterns.
  • Cisterns contain a relatively large number of individual parts, especially moving ones, and require space in the immediate vicinity of the toilet. Even with concealed cisterns, space is required for the flush plate above the toilet bowl.
  • pressure flushers for toilet bowls are known as self-closing fittings.
  • Pressure flushers use the water pressure in the drinking water network for flushing. However, they may only be installed regularly if the water pressure in the supply network is sufficient.
  • Conventional pressure flushers that are mounted in front of or on the wall require comparatively little space, but they still restrict the design of the bathroom or toilet room in question.
  • Pressure flushers also require relatively large pipe cross-sections.
  • Pressure flushers for shallow and deep-flush toilets usually require a water supply line with a nominal width of DN 20 or 3 ⁇ 4 inch, which is why toilet pressure flushers often cannot be used when replacing toilets with existing supply lines.
  • Another disadvantage of pressure flushers is that they typically cannot be integrated into a drinking water hygiene system.
  • the Indian company Hindware presented a wall-mounted toilet bowl in 2020 that does not require a cistern, thereby enabling improved use of the bathroom in question.
  • the flushing device of this toilet bowl is directly connected to the water network.
  • this toilet bowl there is no safety device in accordance with DIN EN 1717 that prevents contaminated liquid from flowing back out of the toilet bowl as a result of back pressure and/or back suction into the water network.
  • the invention is based on the object of creating a device that enables the connection of a toilet bowl to a pressurized water pipe, instead of a conventional cistern, cost-effectively, and enables a high degree of design freedom for the area surrounding the toilet bowl, the current standard DIN EN 1717 for the protection of drinking water from contamination in drinking water installations is essentially fulfilled, can be integrated into an automated drinking water hygiene system and is accessible for maintenance purposes.
  • the stated object of the invention is also achieved by a toilet bowl with a device according to the invention for pressure flushing a toilet bowl according to one of claims 1 to 16; and also by using this device in combination with a toilet bowl without a cistern.
  • the device according to the invention is characterized by a concealed flushing fitting with a first water connection, a second water connection, a line body connecting the water connections to one another and a flushing water outlet formed or attached to the line body, each of the water connections having its own electrically actuated valve is provided, and with a control by means of which the valves can be controlled, and wherein the air inlet opening of the safety device, which prevents contaminated liquid from flowing back out of the toilet bowl as a result of back pressure and / or back suction into a drinking water installation, in a functional assembly arrangement the concealed flush fitting is above an upper edge of the toilet bowl that is relevant for a water overflow, while the concealed flush fitting is below a height of a maximum of 35 cm, preferably a maximum of 25 cm, particularly preferably a maximum of 20 cm, based on the upper edge of the toilet bowl .
  • the inventors have recognized that when flushing a toilet bowl with pressure, it is sufficient to connect a flush fitting intended for this purpose to at least two conventional water pipes, for example a cold water pipe and a hot water pipe, each of which has a significantly smaller nominal diameter than one normally used for a conventional pressure flusher single cold water pipe used, the required nominal diameter of which is at least DN 20 (3/4 inch).
  • the invention makes it possible to supply a toilet bowl with flushing water via at least two water pipes, the pipes each having a nominal diameter of DN 16 or D15, for example. Therefore, the device according to the invention can also be installed cost-effectively subsequently, for example in the case of renovation, if no pipe with a nominal width of DN 20 or larger is available in the drinking water pipe system in question.
  • the device according to the invention thereby enables a cost-effective connection of a toilet bowl to a pressurized water pipe. If the toilet bowl is not to be integrated into an automated drinking water hygiene system in which hot and cold water pipes are flushed separately, it is sufficient to connect the concealed flush fitting of the device according to the invention to a single, suitably sized water pipe, for example a cold water pipe.
  • the water connections can, for example, be designed for connecting a water pipe that has a nominal diameter of DN less than 18, preferably a nominal diameter DN in the range of 16 to 10, particularly preferably a nominal diameter DN in the range of 15 to 10.
  • the water connections of the concealed flush fitting which have their own electrically operated valves, can also be referred to as water inlet connections.
  • the device according to the invention for pressure flushing a toilet bowl does not require a cistern, in particular without a concealed cistern.
  • it does not require an actuation device in the form of a so-called actuation plate, which is conventionally arranged above the toilet bowl.
  • the device according to the invention enables a high degree of design freedom with regard to the area surrounding the toilet bowl, in particular the wall area.
  • a toilet bowl without a cistern can be installed in many more places than one with a cistern, thus creating more design freedom in the bathroom.
  • the elimination of a cistern significantly reduces the number of moving parts and therefore potential malfunctions.
  • the invention also provides additional advantageous degrees of freedom with regard to the design and positioning of the actuating device for triggering the pressure flushing.
  • the safety device which prevents contaminated liquid from flowing back out of the toilet bowl as a result of back pressure and/or back suction into a drinking water installation
  • the safety device having an air inlet opening which, in a functional mounting arrangement of the concealed flush fitting, is above one for a water overflow relevant upper edge of the toilet bowl, the current standard DIN EN 1717 for protecting drinking water from contamination in drinking water installations is essentially fulfilled.
