Definitions

  • the invention relates to a flushing unit with the features of the preamble of claim 1 and a toilet with such a flushing unit.
  • Flushing units are used in public and private sanitary facilities in order to provide a defined quantity of water with which a water closet, often also called a “toilet", can be flushed after it has been used.
  • the flushing unit is mounted above the water closet in order to generate a sufficiently large water pressure via a height difference of the water level in the flushing unit and in a toilet bowl, with which faeces, urine or other waste materials are flushed out of the toilet bowl into the sewage system.
  • a rinsing unit is often also referred to as a cistern.
  • adjustable drain fittings are often installed in the flushing units.
  • a waste fitting is known, which by means of floating chambers and an adjustment mechanism can be adjusted with a closing weight to different discharge quantities of flushing water.
  • rinsing units in which the amount of rinsing water drained is set via the drain fitting have the disadvantage that the drain fittings first have to be removed from the rinsing unit to adjust the amount of rinsing water drained in order to enable access to the fitting. In the case of flush-mounted flushing units in particular, this is often complex and associated with an increased expenditure of time.
  • the invention is therefore based on the object of specifying a flushing unit for a toilet in which different flushing water discharge quantities can be set in a simple manner and with little effort. Furthermore, the invention is based on the object of specifying a toilet with such a flushing unit.
  • this object is achieved with regard to the flushing unit by the subject matter of claim 1.
  • the above-mentioned object is solved by the subject matter of claim 12.
  • a flushing unit for a toilet which has a housing, a filling valve with a flushing water inlet and a drain valve, the filling valve with the flushing water inlet and the drain valve being arranged in the housing.
  • the rinsing unit has a rinsing water outlet to which the drain valve in the housing is connected.
  • the rinsing unit comprises at least one separating element, which is arranged in the housing. The separating element can be moved between an open position and a closed position, the separating element separating at least two water-receiving areas of the housing from one another in the closed position and connecting the two water-receiving areas in the open position.
  • the separating element is arranged between the two water receiving areas in order to connect them in the open position or to separate them from one another in the closed position.
  • the at least two water receiving areas serve to receive flushing water from the filling valve.
  • the filling valve is preferably in fluid communication with at least one of the water receiving areas.
  • both water receiving areas receive water, in particular fresh water, from the filling valve.
  • the filling of one or both water absorption areas depends on whether the separating element is or was in the open position or in the closed position during the rinsing process.
  • the two water intake areas are filled with water at the same time when the separating element is in the open position. In the open position, the two water intake areas form a common water intake area.
  • the separating element releases a passage between the two water-receiving areas of the housing.
  • the two water-receiving areas merge into one another when the separating element is in the open position.
  • the rinsing water contained in the two water intake areas flows out via the drain valve into the rinsing water outlet. This rinsing process corresponds to a rinsing with a large amount of rinsing water drained off.
  • the separating element closes the passage between the two water intake areas.
  • the separating element separates the two water intake areas from one another, so that only the flushing water contained in one of the two water intake areas is discharged.
  • the drain valve is preferably fluidly connected to only one of the two water receiving areas. During a rinsing process or when the drain valve is actuated, only the rinsing water contained in one of the two water intake areas flows out via the drain valve into the rinsing water outlet. This rinsing process corresponds to a flush with a small amount of flushing water drained.
  • the separating element thus enables the realization of at least two different amounts of flushing water, so that the variability of the flushing unit is increased.
  • the water receiving areas are preferably part of an interior space of the housing.
  • the water receiving areas preferably at least partially form an interior space of the housing.
  • the water receiving areas may be part of a water receiving basin.
  • the drain valve is preferably arranged in at least one of the water intake areas in order to discharge flushing water from both water intake areas or from one of the two water intake areas through the flushing water outlet, depending on the position of the separating element.
  • the separating element is preferably physically separate from the drain valve.
  • the separating element is a separate component which can be adjusted between the open position and the closed position, in particular independently of the discharge valve.
  • the partition is preferably a moveable bulkhead.
  • the separating element can preferably be displaced between the open position and the closed position. Additionally or alternatively, the separating element is arranged separately from the filling valve. The separating element can be moved between the two positions independently of the drain valve and/or the filling valve.
  • the separating element is preferably arranged so that it can move vertically between the open position and the closed position. This does not rule out the possibility of an oblique, in particular angled, adjustment of the separating element being possible.
  • the partition member is located between the fill valve and the drain valve, with the fill valve being in a first of the two water receiving areas and the drain valve being in a second of the two water receiving areas.
  • the drain valve and the filling valve are physically separated from one another by the separating element in the housing.
  • the two water intake areas are arranged adjacently.
  • the separating element is preferably arranged standing between the two water intake areas, ie it can be displaced in the vertical direction for opening and closing.
  • both water intake areas are emptied during a rinsing process via the drain valve through the rinsing water outlet.
  • both water receiving areas can be emptied together through the drain valve when the separating element is in the open position.
  • the separating element is arranged in the closed position, only the second water receiving area is emptied during a flushing process. Depending on the position of the separating element, this thus enables rinsing processes with different amounts of rinsing water to be drained off. This is advantageous if, for example, you want to set a larger and a smaller amount of flushing water drained without having to adjust the drain valve and thus without having to remove it.
  • the separating element has at least one overflow edge over which, in the closed position, water flows from the first water receiving area into the second water receiving area during a filling process.
  • the overflow edge is preferably arranged at the top in the installed position and connects the first water intake area to the second water intake area. In the closed position of the separating element, the overflow edge enables the water supplied to the first water-receiving area to be transferred into the second water-receiving area.
  • the filling valve comprises at least one float for opening and closing the flushing water inlet of the filling valve.
  • the float is higher in the installed position than the overflow edge of the separating element, with the separating element being in the closed position.
  • the float can be adjustable in height.
  • the float is preferably guided in a displaceable manner in a longitudinal direction of a valve body of the filling valve.
  • the separating element preferably extends between two oppositely arranged side walls of the housing, wherein in the closed position the separating element for separating the two water-receiving areas is in sealing contact with a bottom of the housing and in the open position for connecting the two water-receiving areas is at a distance from the bottom. In other words, in the closed position, the separating element is in sealing contact with the bottom of the housing. In the open position, the separating element is spaced from the floor.
  • a passage is formed between the two water intake areas, which is delimited by the separating element.
  • this passage is closed.
  • the passage is formed at the bottom in the open position and in the installed position.
  • the separating element is preferably in sealing contact with the side walls. This ensures that during a rinsing process with the smaller amount of rinsing water drained, i.e. when the separating element is in the closed position, the set amount of water is drained through the drain valve.
  • the two side walls preferably form longitudinal sides of the housing.
  • the housing preferably comprises end walls which, together with the side walls and the base, form a trough-shaped section of the housing.
  • a cover section is preferably provided, which is placed on the trough-shaped section.
  • the separating element is preferably flat, in particular in the form of a plate. This has the advantage that the separating element requires little space and thus more space remains in the housing for handling other components, for example during maintenance. In addition, this design provides a compact, convenient form.
  • the separating element is preferably designed in one piece, i.e. monolithically.
  • the separating element can be composed of several, in particular at least two, parts.
  • the separating element is preferably formed from plastic.
  • the separating element can be made of metal. The design of the separating element as a plastic/metal composite is possible.
  • the separating element has at least one latching device, by means of which the separating element can be locked or locked in the open position in such a way that the two water-receiving areas are connected.
  • the latching device holds the separating element in position.
  • the latching connection preferably comprises at least one latching lug and the housing at least one retaining element, in which the latching lug engages in the open position.
  • the holding element has at least one support area on which the latching lug rests in the open position.
  • the holding element preferably comprises at least one extension which corresponds to the latching lug of the separating element in the open position.
  • the latching lug can have at least one form-fitting contour on an underside, which interacts with the extension in the open position.
  • the separating element particularly preferably has at least two latching lugs which are formed opposite one another and extend in opposite directions.
  • the housing can comprise at least two holding elements, one of the holding elements being assigned to one of the latching lugs.
  • the latching lug and the holding element have the simplest possible structural design, so that they can be produced easily and inexpensively.
  • the holding element is preferably part of the housing.
  • the holding element is preferably formed integrally with the housing.
  • the separating element has at least one side edge, which is arranged at least in sections in at least one rail element of the housing for guiding and/or holding the separating element.
  • the separating element is preferably formed by at least one rail element for transferring the separating element between the open position and the Closed position guided laterally. In other words, the separating element is guided by the rail element in the direction of displacement of the separating element.
  • the separating element is thus reliably guided during its movement by the rail element.
  • the rail element serves as a holder for the separating element, in particular when the separating element is in the closed position.
  • the rail element fulfills a holding function in addition to the guiding task, in order to hold or fix the separating element in its position transversely to the rail element, in particular during a filling process.
  • the rail element In the installed position, the rail element is preferably arranged in an upright position, in particular vertically.
  • the rail element can be part of the housing.
  • the rail element is preferably formed integrally with the housing.
  • the two water-receiving areas preferably have different filling volumes for flushing water.
  • the first water intake area can have a filling volume of 0.5 liters to 3 liters.
  • the second water absorption area can have a filling volume of 3 to 7 liters.
  • the first water holding area preferably has a filling volume of 1 liter to 2.5 liters and/or the second water holding area has a filling volume of 4 liters to 6 liters.
  • the first water holding area has a filling volume of at least 1.5 liters and/or the second water holding area has a filling volume of at least 4.5 liters.
  • the two water-receiving areas together have a filling volume of at least 6 liters when the separating element is in the open position.
  • the housing has at least one inspection flap, in particular an inspection cover, through which the separating element is accessible from outside the housing in order to move the separating element into the open position or the closed position.
  • at least the separating element is freely accessible from the outside through the inspection flap. This allows the different amounts of flushing water to be set quickly and easily by moving the separating element between the two positions.
  • the separating element can preferably be adjusted manually, in particular by hand, between the open position and the closed position. It is possible that an adjustment mechanism is additionally or alternatively provided, by means of which the separating element can be displaced between the open position and the closed position, for example by means of a switch and/or button.
  • the invention relates to a toilet, in particular a water closet, with a flushing unit according to the invention and a toilet bowl body which are fluidly connected to one another by at least one line.
