Definitions

  • the present invention relates to a metering unit, in particular a cleaning agent metering unit, for a cistern and a cistern for a sanitary facility.
  • Cisterns are used in particular to flush a sanitary facility, for example a toilet, a bidet or a urinal, with a flushing liquid, in particular with water, preferably with fresh water.
  • a cistern is regularly installed in sanitary rooms in a wall, i.e. flush-mounted, or attached to a wall, i.e. surface-mounted, and is connected to the sanitary facility via at least one pipe. When the flushing is actuated, the flushing liquid flows via the at least one pipe into the sanitary facility in order to flush or clean it or free it from rubbish.
  • the cistern regularly has a flushing liquid receiving space in which an amount of flushing liquid corresponding to the dimensions of the flushing liquid receiving space can be stored or collected for a flushing process.
  • cleaning agents to the rinsing liquid.
  • suitable cleaning agents to the rinsing fluid, the ability of the rinsing fluid to chemically dissolve dirt and debris is improved.
  • Cleaning agents for sanitary facilities are available in particular in liquid form, gel form or solid form, with cleaning agents in solid form being particularly advantageous in terms of their packaging, storage and handling. Cleaning agents for sanitary facilities in solid form are also called toilet tabs.
  • the disadvantage of the aforementioned known solutions is that the dosage of the cleaning agent in the rinsing liquid, that is to say the amount of cleaning agent in the rinsing liquid, that is to say the amount of cleaning agent dissolved or dissolved in the rinsing liquid, cannot be adjusted.
  • the dosage of the cleaning agent corresponds to the amount that is dissolved in the cleaning liquid when the cleaning agent is washed around it. Cleaning as needed is not possible. Rather, the dosage of the cleaning agent in the rinsing liquid is regularly too high or too low, that is, the cleaning agent in the rinsing liquid is over- or undersized.
  • the present invention is based on the object of providing a dosing unit and a cistern which enable a needs-based dosage of cleaning agent.
  • a dosing unit for a cistern having a flushing liquid access for dispensing an adjustable amount of cleaning agent into the cistern comprising a container, the container having an opening for adding the cleaning agent, an inlet connected to the flushing liquid access for flowing in an adjustable amount of flushing liquid and has an outlet for flowing out the adjustable amount of flushing liquid into the cistern, wherein the container is arranged outside, in particular completely outside, of the flushing liquid collected in the flushing liquid receiving space of the cistern.
  • the flushing liquid access can be a water access, in particular a flushing liquid filling valve or filling valve. Due to its special arrangement, the container is only wetted with the flushing liquid and otherwise remains unwetted or dry when flushing is activated.
  • the cistern can be designed as a concealed or surface-mounted cistern for a toilet, a bidet, a urinal or the like.
  • the inlet causes the adjustable amount of rinsing liquid to flow into the container and to flow around the cleaning agent introduced there, so that the cleaning agent is at least partially dissolved in the rinsing liquid.
  • the container arranged outside the flushing liquid collected in the cistern can be arranged, in relation to the position of the flushing liquid, above the maximum liquid level that can be achieved when the cistern is used as intended.
  • the dosing unit can be arranged in the cistern.
  • the container can be designed in one piece or in one piece or in several pieces or in several parts, that is to say comprising at least two components.
  • the dosing unit according to the invention enables a needs-based dosage of cleaning agent in the rinsing liquid, since the amount of rinsing liquid that flows through the inlet into the container holding the cleaning agent can be adjusted.
  • This amount of Rinsing liquid can be adjusted by choosing rinses of different lengths in terms of time or of different sizes in relation to the volume of rinsing fluid or by adjusting the flow rate of the rinsing fluid, in particular by adjusting the cross section through which the rinsing fluid flows, also called flow cross section.
  • the amount of cleaning agent in the rinsing liquid can thus be adjusted by adjusting the amount of rinsing liquid that flows through the inlet into the container holding the cleaning agent.
  • the amount of cleaning agent dispensed into the cistern that is to say the dosage of the cleaning agent in the rinsing liquid, is no longer dependent on the time that has passed between the individual flushes, since the cleaning agent is not in the rinsing liquid held in reserve . Instead, with each flush, the same, adjustable amount of cleaning agent is always released into the flushing liquid held in the flushing liquid receiving space of the cistern. This effectively prevents overdosing or underdosing of cleaning agent.
  • the dosing unit according to the invention enables the cleaning agent to be dried between the respective rinses, so that efficient use of the cleaning agent is ensured.
  • the dosing unit according to the invention is back-suction-proof with regard to DIN EN 1717 (protection of drinking water), since the inlet is a free inlet, i.e. the rinsing liquid flows through the inlet into the container in a free fall. This always ensures a separation between the drinking water level and the inlet of the dosing unit according to the invention.
  • the dimensioning of the separation depends on the design of the container and is in particular at least 20 mm.
  • the opening of the container can be an opening in the lateral surface forming the container that faces away from the liquid level of the flushing liquid collected in the cistern.
  • the container can be designed to be open at the top.
  • the size of the opening should be dimensioned according to the size of the cleaning agent to be added to the container. If the cleaning agent is a toilet tab, the size should, for example, be such that a toilet tab can be placed in the container.
  • the inlet of the container can be connected to the flushing liquid access via a flushing liquid hose.
  • the flushing fluid hose is also called a bypass.
  • the inlet can further have a hose nipple, in particular formed on it, that is, formed monolithically or in one piece with the inlet. This strengthens and stabilizes the connection between the inlet and the flushing fluid hose and simplifies assembly of the flushing fluid hose to the inlet.
  • the inlet of the container can be designed such that the incoming rinsing liquid falls onto the cleaning agent due to gravity.
  • the inlet can be formed in an upper region of the container in relation to the position of the cleaning agent within the container. This ensures that the cleaning agent is effectively flushed with the rinsing liquid.
  • the outlet of the container can be an opening in the lateral surface forming the container that faces the liquid level of the flushing liquid collected in the cistern.
  • the container can be designed to be open at the bottom or the outlet can be designed in the bottom of the container.
  • the size of the outlet should be chosen so that, on the one hand, the cleaning agent to be added to the container remains safely in the container when the rinsing liquid is washed around it and, on the other hand, the rinsing liquid can flow out quickly.
  • the outlet may have a slot shape, a hole shape, a grid shape or a mixture of at least one of these shapes.
  • the container can have a cuboid shape, a cylindrical shape, a spherical shape, a teardrop shape, a cone shape or a mixed shape of at least one of the aforementioned shapes. These container shapes ensure that the cleaning agent is effectively flushed with the rinsing liquid.
  • the container can be arranged in the immediate vicinity of, in particular below, an inspection, maintenance or filling opening of the cistern. This enables easy filling with cleaning agent and maintenance of the dosing unit.
  • the container can have a support structure for attaching the container, in particular for attaching the container to or in the cistern.
  • the support structure can have reinforcing, guiding, locking, frictional and/or positive locking elements. This simplifies the assembly of the dosing unit.
  • the support structure can be designed as a component that can be connected to the container, or as a molding of the container, that is to say it can be designed monolithically or in one piece with the container.
  • a cistern for a sanitary facility is proposed, comprising the dosing arrangement according to the invention.
  • Figure 1 shows an embodiment of the dosing unit according to the invention in a schematic representation diagonally from the front.
  • the dosing unit is in a rinsing liquid access 1 (shown in Figures 3 to 5 ) in the form of a filling valve having a cistern 2 (shown in Figures 4 and 5 ) installed for the purpose of dispensing an adjustable amount of cleaning agent 3 in the form of a toilet tab into the cistern 2.
  • the dosing unit comprises a container 4, the container 4 having an opening 5 for adding the cleaning agent 3, an inlet 6 connected to the flushing liquid access 1 Inflow of an adjustable amount of flushing liquid and an outlet 7 for flowing out of the adjustable amount of flushing liquid into the cistern 2, the container 4 being arranged outside the flushing liquid collected in the cistern 2.
  • the essentially cuboid container 4 is designed to be open at the top.
  • the opening 5 is designed as an opening in the lateral surface forming the container 4, specifically on the side facing away from the liquid level of the flushing liquid collected in the cistern 2.
  • the opening 5 is dimensioned so that the cleaning agent 3 in the form of a toilet tab can be easily poured into the container 4.
  • the inlet 6 is connected to the flushing liquid access 1 via a flushing liquid hose 8.
  • the inlet 6 is arranged above the cleaning agent 3 introduced into the container 4, so that the rinsing liquid flowing into the container 4 falls onto the cleaning agent 3 due to gravity and in this way effectively washes around it.
  • the outlet 7 is formed on the side of the container 4 opposite the opening 5, that is to say in the bottom of the container 4.
  • the outlet 7 is designed as a slot-shaped opening in the lateral surface forming the container 4, namely on the side facing the liquid level of the flushing liquid collected in the cistern 2. Compared to the opening 5, the outlet 7 is smaller, so that the cleaning agent 3 When flushed with the rinsing liquid, it remains safely in the container 4 and the rinsing liquid can flow out of the container 4 quickly.
  • the container 4 also has a support structure 9 for fastening the container 4 in the cistern 2.
  • Figure 2 shows the embodiment Figure 1 in a schematic representation from below.
  • the outlet 7, designed as a slot-shaped opening, is arranged centrally in the bottom of the container 4.
  • the bottom of the container 4 is reinforced by molded ribs in order to withstand the mechanical stress caused by the washing liquid falling into the container 4.
  • the support structure 9 has guide elements in the form of a rail-shaped molding, locking elements in the form of an undercut and positive locking elements in the form of a recess in order to simplify the assembly of the dosing unit in the cistern 2.
  • Figure 3 shows the embodiment from the Figures 1 and 2 in partial assembly in a schematic representation from diagonally behind.
  • the inlet 6 of the dosing unit is connected to the flushing liquid access 1 of the cistern 2 via the flushing liquid hose 8, so that flushing liquid can flow into the container 4 via the flushing liquid hose 8 through the inlet 6 into the container 4 when a flush is actuated from the flushing liquid access 1 to rinse around the cleaning agent 3 added and finally flow out through the outlet 7 into the cistern 2, more precisely into the rinsing liquid receiving space of the cistern 2.
  • FIG 4 shows an embodiment of the cistern 2 according to the invention in a schematic representation from the front.
  • the cistern 2 is installed in a sanitary facility and comprises the embodiment of the dosing unit according to the invention Figures 1 to 3 .
  • the container 4 is arranged outside the flushing liquid collected in the flushing liquid receiving space of the cistern 2, so that it is only wetted by the flushing liquid when a flush is activated.
  • the maximum achievable liquid level 10 of the rinsing liquid collected in the cistern 2 when the cistern 2 is used as intended is completely below the position of the container 4, so that the container 4 is not wetted by the rinsing liquid collected in this way, so that Cleaning agent 3 within the container 4 is also not wetted by the rinsing liquid collected in this way, unless rinsing is activated.
  • Figure 5 shows the embodiment Figure 4 in a schematic representation from diagonally behind.
