Definitions

  • the present invention relates to an inlet fitting for a cistern according to the preamble of claim 1.
  • Inlet fittings are used for filling cisterns of sanitary items, such as toilets or urinals.
  • the filling should be done in a relatively short period of time, so that the flushing is quickly operational again.
  • the noise should be small, so that the user can not perceive the filling acoustically.
  • the invention has for its object to provide an inlet fitting, which allows a low-noise filling of the cistern.
  • the inlet fitting for the filling of a cistern comprises a water channel with an inlet and an outlet for supplying flushing water into the flushing cistern, a junction box providing the inlet and a first portion of the water channel, having a connection pipe for connection to a supply pipe, a pipe casing communicating with the junction box, which adjoins the first section and in the installed position along a vertical axis extending second portion of the water channel provides, the second portion terminates with the outlet, and arranged in the water channel control valve for controlling the inflow from a supply line.
  • a backflow element is arranged, which is closed or substantially closed at the beginning of the filling of the water channel, wherein the water flowing into the water channel is dammed in the water channel, and which back pressure element opens upon reaching a water pressure, so that the water from the Water channel flows into the cistern.
  • the diameter of the second vertically extending portion between the end of the first portion and the backwater member is substantially constant and is formed by the inside of the pipe casing. This means that there are no backflow forming elements in this area.
  • the backflow element preferably comprises a closure seat arranged in the region of the outlet and a closure member which can be moved relative to the closure seat.
  • the closure member lies while the closure seat until the said water pressure is reached.
  • the closing element is moved away from the closure seat by the applied water pressure.
  • the backflow element comprises a restoring element, in particular a spring element, which acts on the backstop element, in particular on the closure element, provides a restoring force.
  • the return element is brought back into the closed position by the return element.
  • the return element is preferably arranged between the tube housing and the closure member, wherein the closure member is moved by the return element against the valve seat.
  • the return element can also be arranged outside the water channel.
  • the backflow element closes the outlet substantially completely, so that at the beginning of the filling no or substantially no water can pass through the backflow element.
  • the backflow element allows leakage, whereby the cistern is slightly faster filling.
  • then located in the water channel air can escape through the backwater.
  • the leakage can be provided in various ways. For example, by a mechanical interruption of the closure member or by a correspondingly sized return element.
  • the closure seat is a valve seat and the closure member is a valve body movable to the valve seat.
  • the valve body rests against the valve seat and is moved on reaching the water pressure of the same way.
  • the valve seat and closure body are preferably in communication with the pipe housing and are mounted in the water channel.
  • a bearing point extends into the pipe housing. At the bearing point and the return element can be arranged.
  • the closure seat is formed by the end face of the tubular housing bounding the water channel and the closure member is a flap which can be pivoted to the front side. The closure flap rests against the front side and is moved away from it when the water pressure is reached
  • the closure flap is preferably mounted via a bearing point arranged outside the water channel. At this bearing also the reset element can also be arranged, which then acts on the flap.
  • control valve is arranged in the first section and is preferably controllable via a float with respect to the water level in the cistern.
  • the inlet fitting in the connection housing on a balancing valve for the compensation of a negative pressure in the supply line.
  • the balancing valve preferably comprises a vent opening, wherein the vent opening can be closed by the water itself or by a closing body which can be moved through the water when the water level rises in the water channel.
  • the balancing valve is preferably a closure body that can be moved by the water onto the ventilation opening, wherein the closure body is preferably part of a diaphragm valve.
  • the balance valve is an overflow tube having an inlet projecting into the second section and an outlet standing above the water surface, the outlet acting as a vent opening.
  • the inlet can be closed here by the rising rinse water. The closing can further prevent the formation of noise.
  • a further tube housing is arranged parallel to the tube housing, in which the overflow tube opens with the outlet.
  • the water when the backwater is still closed, flow over the overflow pipe and the other pipe housing in the cistern.
  • the backflow element When the backflow element is open, the water can flow into the flushing cistern via the further tube housing and the tube housing provided with the backflow element. As a result, a splashing or other noise can be prevented.
  • An arrangement comprises a cistern and an inlet fitting according to the above description.
  • the inlet fitting is arranged in the cistern, wherein the tube housing in the mounting eye is substantially perpendicular to the water surface of the water located in the cistern.
  • Next is the inlet fitting with a supply line in connection.

  • control unit 27 for controlling the control valve 10 is shown on the inlet fitting.
  • This control unit 27 here comprises a float 28, which communicates with a rod 29 with the control valve 10 in connection.
  • the buoyancy of the float 28 drops and it moves down, causing the rod 29 is moved and the control valve 10 opens.
  • the buoyancy force acts on the float 28 so that it is moved back up and the control valve 10 closes again when it reaches the level.
  • the control unit 27 may also be designed differently.
  • FIG. 3 which shows a sectional view through the inlet fitting 1

  • the air can also be led away from the water channel 2 otherwise.
  • the backwater element 11 Upon reaching a predetermined water pressure within the water channel 2, the backwater element 11 opens so that the water from the water channel 2 can flow into the cistern. Depending on the dimensioning of the backflow element 11, this opens upon reaching a static pressure through the water column in the water channel 2 or through the present in the connecting line water pressure of the pipe network, which acts on complete filling of the water channel 2.
  • the backflow element 11 comprises a closure seat 12 arranged in the region of the outlet 9 and a closure member 13 which can be moved relative to the closure seat 12 At rest, the closure member 13 abuts the closure seat 12 and is then moved away from the closure seat 12 upon reaching the above-described water pressure, so that a passage between the closure seat 12 and closure member 13 is provided. Through this passage, the rinse water can leave the water channel 2 in the cistern.
  • the backflow element 11 further has a restoring element, here in the form of a spring element 14, which provides a restoring force on the backflow element 11, in particular on the closure member 13.
