Definitions

  • the present invention relates to a toilet bowl with inlet for rinsing liquid and a siphon in a lower portion of the basin and a flushing system for such a toilet bowl according to the preamble of the independent claims.
  • the invention relates to a toilet bowl and a flushing system that are suitable for displacement toilet facilities.
  • the requirements for the flushing behavior of lavatory systems are manifold. Almost every country has its own standard. This standard defines the complete, partial and post ⁇ running volumes of rinse water.
  • various paper specifications to be used such as the suction behavior, size and number of sheets, as well as the different specimens in their specific type (size, weight, material and stiffness).
  • the uncleaned area is also a measured variable and must be measured according to national specifications.
  • the energy of the water during the flushing process is of crucial importance. While the water energy, ie, a purge flow, also by standards, such as by a Spülkastenstandard, is specified, no specifications are provided for the design of the toilet interior.
  • a toilet bowl has an inlet for rinsing water in an upper basin area and an outlet with a siphon in a bottom area of the basin. Through the inlet water flows into the interior of the toilet bowl and from there due to gravity through the siphon. A siphon content is displaced by the inflowing water and flushed into a connected wastewater network. The siphon is filled with pure water until an odor trap is made. Toilet systems with this mode of operation are referred to as displacement WC systems. Toilet bowls are known from the prior art, which have an annular channel at an upper edge of the basin with multiple outlets.
  • the main part of the water is passed through the purge ring, meets in the middle on a front side of the basin and then presses as siphon horizontally in the basin escaping the siphon content through the siphon into the sewage network.
  • a smaller proportion of the rinsing water exits through defined, usually radially arranged flush holes on the ring and flushed in the best case, the entire basin inside.
  • Water also flows out of the flushing ring on the inside of the basin closest to the water inlet.
  • the water outlet is arranged in such a way that the paper in the siphon is immediately submerged in water to prevent it from floating.
  • a flushing system for a toilet bowl in which rinse water flows from a cistern to a manifold on a rear side of the toilet bowl and is divided there.
  • a first part of the rinse water flows through opening slots tangentially along an inside of the basin.
  • a pool edge limits the rinse water flow upwards, so that it runs on both sides over the inside and finally after drains down.
  • a second portion of the rinse water flows from the manifold through a channel that winds down the back of the outside of the pool and to a front side of the pool.
  • the rinse water exits the channel in the form of a jet into the drain.
  • this type of toilet bowl of Spülwasserstrom is already divided at the pool inlet and can be discharged through the rear channel with a large cross-section or directly into the pool.
  • a flushing system for a water closet in which the rinse water from the cistern is passed to a ring channel and a peripheral channel.
  • the annular channel is a peripheral channel at the upper edge of the basin with a plurality of circumferentially distributed openings from which rinse water is discharged towards the basin interior surface.
  • the peripheral channel consists of two channel arms, which surround the toilet bowl on the outer circumference and open at a front in a common outlet, which is below the waterline of the odor finish and is discharged through the rinse water in the siphon.
  • This object is achieved by the invention by a toilet bowl and a flushing system with such a toilet bowl according to claims 1 and 14.
  • Advantageous embodiments and further embodiments are described in the dependent claims.

  • the flushing ring channel communicates with the inlet, ie it is with the Inlet in fluid communication and can be filled via the inlet with rinsing liquid.
  • the purge ring channel may form an upper edge of the basin which serves as a support for a toilet seat or a toilet lid.
  • the inner surface is z. B. cup-shaped and may have different depths and diameters depending on the design of the toilet bowl. In most cases, the pelvis has an oval shell shape such that a first region of small radius forms a rear region having the inlet, and an opposite second region of small radius forms a front region.
  • the side areas of the basin have a larger radius.
  • the inner surface extends substantially between the upper edge of the basin and the bottom area of the siphon as well as around the basin. In the bottom area of the basin, the inner surface is therefore covered flushing liquid, which accumulates in the siphon and forms an odor trap.
  • At least one flushing channel is provided in the toilet bowl, which communicates with the inlet via the flushing ring channel. Accordingly, the rinsing liquid is passed from the inlet through the purge ring channel to at least one purge passage and fed through an annular channel outlet into the purge passage.
  • the at least one flushing channel is thus indirectly connected to the inlet.
  • the at least one flushing channel extends from the flushing ring channel in the direction of the siphon and has a channel outlet which opens out of the inner surface into the basin in a lower pool area.
  • the energy of the rinsing liquid introduced through the inlet can be transferred via the annular channel and through the at least one flushing channel bundled into the lower basin area without the rinsing liquid between the flushing ring channel and the flushing channel is split.
  • a large pressure can be built up in the siphon, as a result of which objects located therein are reliably rinsed out.

  • the outlet area of the annular channel outlet can also be larger than the area of all annular openings taken together.
  • the annular channel outlet from the flushing ring channel is provided to the flushing channel on a side of the basin opposite to the inlet for flushing liquid, ie, for. B. on a front of the basin, while the inlet is provided on a rear side.
  • the rinsing liquid is introduced on both sides of the pool in the flushing ring ⁇ channel.
  • a purge liquid stream flowing around to the left and to the right is provided, which respectively flow to the ring channel outlet. This quickly builds up a uniform pressure in the purge ring channel.
  • the at least one flushing channel is arranged as a front flushing channel on the tank, so that the at least one flushing channel is provided on the front of the tank, while the inlet for flushing liquid is provided on the rear side facing the front side.
  • the siphon is, as usual, bent from the front towards the rear side.
  • the rinse liquid therefore enters through the channel outlet in a lower pelvic area a front of the basin from the inner surface.
  • the outgoing jet is therefore directed from front to back and provides a strong current through the siphon.
  • exactly one flushing channel with channel outlet is provided, wherein the flushing channel and the channel outlet are arranged centrally on the front side of the basin.
  • the flushing liquid therefore places on both sides of the basin the same path in the flushing ring channel to the annular channel outlet and back into the flushing channel.

  • the at least one flushing channel preferably runs in a direct line from the ring channel outlet to the channel outlet, ie from the upper edge of the basin in the direction of the siphon. In this leadership of the scavenger this runs approximately vertically, so that the water gains energy due to gravity.
  • the flushing channel runs along the shortest path along the toilet bowl from the upper edge to the lower area of the basin, so that a quick purging of the basin is possible. It is advantageous if a peripheral wall of the scavenging channel between the annular channel outlet and the channel outlet is closed, so that no flushing liquid exits on this route and this exits the channel outlet with full energy.
  • the channel outlet of a flushing channel is located above an odor trap of the siphon.
  • the rinsing liquid therefore occurs above the liquid level in the siphon However, in a lower region of the basin, so at least below half the basin depth. It is advantageous if a lower edge of the channel outlet lies on a plane with the odor trap, ie on a plane at normal or average level of the siphon.
  • the rinse liquid is passed directly to the liquid surface of the siphon. An uncontrolled displacement of the siphon liquid with undesirably strong spraying is therefore avoided.
  • the channel outlet may be elongate, z. B. as a wide slot, and with a long edge, in particular the lower edge, parallel to the surface of the odor trap.
  • the flushing channel preferably has an inner region or cross section which is shaped in the same way over its length.
