Definitions

  • the present invention relates to a device for cleaning a sanitary facility.
  • the sanitary facilities for which the device can be used are primarily toilets, but the device can also be used in the same way for washbasins, bidets, showers, bathtubs and urinals and other drains through which water flows.
  • the device can be adapted to the respective intended use.
  • the device according to the disclosure DE 88 14 729 U1 works.
  • a bell-shaped rubber bead is arranged on a handle, which is inserted into the drain of a toilet with the bell opening at the top.
  • the rubber bead adapts to the shape of the drain and closes the drain when the toilet bowl is filled with cleaning liquid. Because there is no overflow, this type of cleaning can result in the user filling the pool with too much cleaning liquid, causing an overflow.
  • not every area of the toilet bowl can be reached by the cleaning liquid, since dirt residues cannot be reached or are even collected below the rubber bell and especially in the area of the rubber bell pressed against the drain pipe. This can lead to unwanted dirt edges.
  • the device known from US Pat. No. 6,405,385 B1 comprises an elastic body which can be inserted into the drain of a toilet bowl. By actuating a bellows, the thickness of this elastic body can be changed by pumping in air in such a way that the elastic body fits snugly against the drain wall and prevents water from flowing out. A cleaning liquid filled into the toilet bowl is used to clean the bowl.
  • a shut-off bladder is inserted into the drain and filled with air by actuating a bellows. Filling with air can lead to the previously recognized problem of dislodgement from the drain pipe. Furthermore, the contact between the bladder and the drain pipe is again very great, so that large parts of the sanitary facility cannot be cleaned. Here, too, there is no overflow, which simplifies cleaning. In addition, the bladder cannot be pushed far enough into the drain pipe, so that the cleaning effect can be reduced in the area of the drain that is still visible.
  • the object of the invention is to provide a device for cleaning a sanitary facility that does not easily detach itself from the sanitary facility to be cleaned during use and can be individually adapted to different types of sanitary facility.
  • a device for cleaning a sanitary facility comprises a variable-size bladder for closing a drain of a sanitary facility, a hose connected to a first end with the bladder, a valve connected to a second end of the hose and a bellows.
  • the device for cleaning a sanitary facility is characterized in that a bubble core is arranged inside the bladder and an overflow is arranged on the device. After the device for cleaning a sanitary facility has been inserted into the sanitary facility, the overflow is arranged with its upper edge below an upper edge of the sanitary facility. For this purpose, the overflow is fluidically connected to a first end of the bladder core.
  • a downcomer is located at a second end of the bladder core.
  • the downcomer also serves to control the introduction of the pre-inflated bladder with the bladder core.
  • the bubble is directed early on when it is inserted into the drain of the sanitary facility by the drain connector pushed ahead within the drain and the risk of the process being slowed down by impact of the preferably rubber-like bubble on the Drainage wall bypassed or at least reduced.
  • the bladder can be pushed far into the drain pipe both around a first bend and around a second bend of the drain pipe with the help of the drain connector. This also increases the cleaning effect far into the drain pipe.
  • the fluidic connection of the overflow with the bladder core and the outlet nozzle allows excess cleaning liquid to be discharged behind the bladder into the outlet of the sanitary facility after the device for cleaning a sanitary facility has been inserted into the sanitary facility. This means that no additional devices such as buckets or bowls have to be kept outside of the sanitary facility.
  • the drain pipe is designed in a flat S-curve shape.
  • This flat S-curve shape greatly facilitates both the deflection of the front end of the device around the drain bend at the bottom of the plumbing fixture and further advancement within the drain.
  • the drain connector is attached in the axis of the bladder core, but then bends in a usage position of the device to the floor of the sanitary facility and in a further arc into a course parallel to the axis through the bladder core, an optimal introduction of the device into the Process guaranteed.
  • the S-shape is preferable for use in toilets.
  • the bladder core and/or the outlet nozzle have an oval cross-section.
  • the drain socket should not twist, so that correct drainage from the overflow is guaranteed. It has been shown that an oval design of the bubble core contributes to the fact that the discharge nozzle when Insertion of the device remains stable in the plumbing in its position at the end of the sanitary facility. Twisting is prevented by the oval shape of the bladder core.
  • the device for cleaning a sanitary facility can be attached or hung on the sanitary facility by means of a holder or in the sanitary facility.
  • the device is held securely on the sanitary facility. In this way, the device can be kept outside of the cleaning liquid, particularly during longer exposure phases to the cleaning agent after the outlet has been closed by means of the bladder.
  • the overflow hose is guided at least in part through the hose and the bladder in a first form.
  • the overflow hose is routed at least partially around the hose and through the bladder.
  • the overflow on the holder and / or the hose is held adjustable in height by means of an overflow holder. In this way it can be achieved that a precise fill level of the cleaning liquid is always reached for the most far-reaching cleaning of the sanitary facility. This improves the cleaning result.
  • the overflow is arranged such that after Insertion of the device for cleaning a sanitary facility in the sanitary facility that is arranged with its upper edge below an upper edge of the sanitary facility.
  • the sanitary facility can thus be filled with cleaning fluid without hesitation - whether via a water tap, by flushing or in some other way - without the user having to fear that the water filled in will run out over the upper edge of the sanitary facility.
  • care must be taken to ensure that it can also take up and discharge larger quantities, for example from flushing a toilet, in a short time.
  • a shape-unchangeable hollow body is arranged on the valve, which can be filled with a liquid.
  • Water can preferably be used here, but any other liquid that is heavier than water can also be used in the same way.
  • a shape-changing balloon is in turn arranged, which is fluidically connected to the bellows. Actuation of the bellows results in air being pumped into the balloon, which displaces the liquid in the rigid hollow body. This fluid is fed through the tube into the bladder, which then expands and blocks the drain.
  • the hose has a length that makes it possible to push the bladder around at least one bend in the drain pipe and into the drain pipe. In this way, all visible but also non-visible areas of the inside of the sanitary facility to be treated can be cleaned.
  • the shape-unchangeable hollow body should have a volume that is at least as large as the volume of the bladder when it is used in a large drain of a sanitary facility specified according to DIN. It is also advantageous to design the valve in such a way that separating the hollow body from the valve does not result in the liquid escaping from the hose or the bladder, but this can only be done by appropriate actuation by the user.
  • the shape-unchanging hollow body has an inlet which can be closed in a pressure-tight manner. Through this, the liquid inside the shape-unchangeable hollow body can be exchanged or drained for storage of the device.
  • the pressure resistance prevents liquid trapped in the shape-invariable hollow body from escaping through the inlet when the bellows is actuated.
  • the inlet can be designed, for example, as a screw cap or plug.
  • a balloon valve is arranged in the fluidic connection between the bellows and the balloon.
  • the bellows can thus be actuated several times in order to pump larger amounts of air into the balloon to displace the liquid into the shape-invariable hollow body without the air escaping from the balloon again.
  • the balloon valve should be designed in such a way that actuation of a vent allows the pumped-in air to escape from the balloon. Backflowing liquid facilitates the detachment of the bubble from the drain pipe.
  • the overflow or overflow holder are connected to the bladder core by means of a chain.
  • This chain is used to secure the part of the device that is stuck in the drain against being flushed away if the overflow hose tears off the bubble core, for example, or detaches from it in some other way.
  • such a chain has the purpose of protecting the hose or the overflow hose from excessive kinking, so that water can be released into the outlet behind the filled bladder at any time without any problems, should this become necessary.
  • the device for cleaning a sanitary facility has a volume-reducing element, the volume-reducing element being an open-topped basin which can be inserted into the sanitary facility.
  • a bowl-like volume reduction element can be provided for a washbasin, for a toilet bowl it should have more of a box shape.
  • At least one support arm is arranged at the upper end of the basin, which is used to hang the volume-reducing element on or into the sanitary facility. It is important to ensure that the outside does not come into contact with the inside of the sanitary facility, as otherwise the cleaning result at the points of contact may be impaired.
  • the amount of water required for the cleaning process can be reduced with this volume-reducing element, since after closing the outflow by means of the bladder, only a volume of water reduced by the volume of the volume-reducing element can be let into the basin.
  • the volume-reducing element must be fastened to the sanitary facility in such a way that water running into the sanitary facility does not allow the volume-reducing element to float. For this purpose it can be clamped or strapped on, for example. Other types of fastening are possible. Handles that are arranged on the upper side of the volume-reducing element are advantageous. With the help of this, the volume reduction element can be lifted out of the sanitary facility, even when it is filled.
  • the volume-reducing element has a closable water inlet and outlet on its underside. Water can penetrate through this into the volume-reducing element when the sanitary facility is being filled. Once the water inlet and outlet are closed, the water will remain in the volume reduction element even if multiple cleaning cycles are performed.
  • the simplest type of closure is realized by a grid in the floor with a rubber mat lying above it, the rubber mat being connected to the volume-reducing element at least on one side. Penetrating water lifts the rubber mat, when full the water in the volume reducing element presses the rubber mat onto the grid and thus closes the water inlet and outlet.
  • a temporary inflow of water into the volume-reducing element can also be made possible, for example, by a rotary mechanism or a valve or in some other way.
  • the holder can be removed from the device and has a shape at least at one end of the holder that is adapted to the shape of the hose or the overflow hose.
  • the holder can thus fulfill a second function when inserting and removing the device in the sanitary installation, since it can be used to guide the hose around at least the first bend in the drain. Guiding is supported by a semicircular groove which is suitable for enclosing at least a small part of the hose or the overflow hose.
  • the device with the bladder and the hose first can be partially inserted into the drain of the sanitary facility, with the holder being able to help. Reach a position beyond the first with the bubble or rather the second bend in the drain of the sanitary facility, the bladder can be filled by actuating the bellows and the drain can be blocked in this way.
  • the volume reduction element can now also be installed.
  • the sanitary facility can now be filled with a cleaning fluid, with cleaning agent being added to the existing flushing water of a toilet during at least one flushing process or a desired amount of water by opening a faucet in a shower or sink.
  • the cleaning liquid can be let in up to a desired filling level and then left in the device for a desired period of time, for example overnight or even over a whole weekend.
  • the cleaning agent has a higher cleaning power, especially in the case of natural or ecological cleaning agents. Too much cleaning liquid is discharged directly into the drain via an overflow. After the cleaning is completed, the bladder is returned to its original shape by opening the valve and emptying it, so that the cleaning liquid with the particles it contains can flow out through the drain of the sanitary facility.
  • the use of a liquid as a filler for the bubble to be used in the outflow is advantageous since this bubble is prevented from floating up due to the absence of air.
  • a pushing is achieved behind a bend or in the area of an odor trap. This increases the area of influence of the cleaning liquid and improves the overall cleaning result.
  • the cleaning process no longer has to be completed manually, since, for example, the intensive cleaning of the inner edge of the toilet bowl is no longer necessary or at least is made easier. All areas of the sanitary facility that can be viewed by the user can be cleaned in one cleaning process. This is possible despite the use of the device because it is in the visible range not or hardly touches the sanitary facility.
  • the cleaning liquid simply flows out through the drain of the sanitary facility.
  • the device can be used for toilets as well as for washbasins, kitchen sinks and shower drains, since the exchangeable hoses and bladders can be used to adapt to the respective pipe diameters of the drains. If particularly thin hoses and elongate foldable bladders are used, it may also be possible to pass these elements through a sieve arranged in the outflow area of, for example, a washbasin.
  • the advantage of such a design is that the hose and bladder can then be easily taken along by the water flowing out and placed in the correct place in the drain before the bladder is filled with liquid. With suitable additives, an adaptation to pond or swimming pool facilities can also be achieved.
  • the hollow body can be coupled to several hoses at the same time, so that, for example, adjacent drains from washbasins in toilet rooms in large facilities can be cleaned simultaneously with one hollow body.
  • a large number of hoses, especially with different diameters, can also be used to clean different sanitary facilities in a bathroom one after the other without the need for several hollow bodies.
  • the drains from the shower/bathtub and washbasin can also be sealed with other bladders.
