Description

The present invention relates to a Sanitärspüleinrichtung, this is in addition to a flushing device for a toilet also understood for a urinal or the like, with a cistern, especially for flush mounting, and a device for supplying detergents and / or fragrances in a sanitary basin, said the device has a temporary storage for the temporary admission of a certain dose of cleaning agents and / or fragrances, which is connected in the flow direction after the cistern to a rinse water leading to the sanitary basin flushing pipe so that a portion of the rinse water can rinse the temporary memory temporarily during a rinsing process , wherein in the buffer, a device is provided which allows the rinse water to flow into the buffer faster than the mixture of rinse water and detergents and / or perfumes flows. Furthermore, the invention relates to a corresponding flushing pipe for a Sanitärspüleinrichtung. Such a sanitary flushing device and such a flushing pipe are known for example from the BE 503 098 A ,

Further Sanitärspüleinrichtungen, which have at least one buffer for temporarily receiving a certain dose of cleaning agents and / or fragrances are known, for example from the GB 1 180 575 A , of the WO 99/08076 A1 , of the US 1,211,137 , of the EP 0 579 581 A1 , of the EP 0 338 825 A1 as well as the DE 297 07 778 U1 ,

From the described prior art, various types of supply of cleaning agents and / or fragrances are known. For example, a basket-shaped vessel with a usually formed as a solid body detergent and fragrance is hung in the sanitary basin in the area in which the fresh rinse water flows into the basin. With each rinse, a relatively large amount of the detergent and fragrance is mixed with the rinse water so as to effect the desired cleaning effect and fragrance development simultaneously with the rinsing process.

Since such a so-called toilet block on the one hand is relatively expensive to assemble, but on the other hand also in the assembled state in the sanitary basin is distracting, an automated supply of cleaning agents and / or fragrances is increasingly used. Such a device for supplying cleaning agents and / or fragrances usually has a simply constructed metering device, which is mounted in the cistern. In this case, the metering device and at least part of a storage tank is below the water level in the filled state of the cistern to allow a release of the detergent to the rinse water. The release of the cleaning agent and the fragrances takes place during or directly after a reference of rinse water to the rinsing water in the cistern. If the entire cleaning agent has been used up from the storage tank, the user must refill a pre-portioned amount of detergent into the storage tank. For this purpose, the user must remove the cover of the sanitary sink and in the at least partially located below the water level Dosing fill a new detergent portion. This is feasible for a simple user only with cisterns that are installed in front of a wall and are therefore easily accessible. In new installations and renovations of older sanitary facilities, however, nowadays almost exclusively Sanitärspülkästen wall installation, ie in-wall construction, realized. These are no longer easily accessible to the user, which is why such dosing devices are unsuitable for supplying detergents and / or fragrances in a sanitary basin for wall installation cisterns.

A further development is from the DE 103 30 323 A1 known, which describes a detergent unit for supplying detergents and / or fragrances in a toilet bowl. This detergent unit comprises a metering and dispensing device, which is electrically actuated and emits the cleaning agent and / or fragrances in an overflow pipe of a drain valve or in the toilet cistern. The entire detergent unit is arranged in the cistern, which can be designed in particular for wall mounting.

However, some sanitary flushing devices with a device for supplying cleaning agents and / or fragrances have the disadvantage that the majority of the cleaning agents and / or fragrances during the rinsing due to the previous mixing in the interior of the cistern with the entire rinse water together with the rinse water largely unused the toilet drain pipe is flushed away. After rinsing, only a small residue remains in the puddle of water in the sanitary basin. Most of the added detergent and / or perfumes flows only briefly along the wall of the sanitary basin, but is then discharged directly through the drain.

In addition, due to the mixing with the rinse water in the cistern, the remaining remainder of the detergent and / or fragrance in the puddle of water in the puddle is very much diluted. To achieve a sufficient cleaning effect and fragrance development so a relatively high dosage of the detergent or perfume is required

A buffer as described in the documents mentioned above avoids these disadvantages. It has a device in the cache, as shown in the BE 503 098 A is known and allows a faster inflow of the rinsing water as an outflow of the mixture, the advantage that the detergent and / or the fragrance can mix better with the rinse water. The device has for this purpose a specially shaped tube which protrudes with its one end into the flushing pipe and is connected at its other end to the buffer, in which in turn a detergent and / or perfume can be added. The projecting into the flushing pipe end of the tube is provided with a relatively large inlet opening and a relatively small drain opening. Both openings are provided in the jacket of the tube, wherein the larger inlet opening in the flushing pipe protrudes vertically upwards and the smaller discharge opening in the flushing pipe protrudes in the opposite direction. Front side, the tube is closed at this end.

It is therefore the object of the present invention to provide a Sanitärspüleinrichtung with a device for supplying detergents and / or fragrances, in which the addition of cleaning agents and / or perfumes optimized and thus their efficiency is increased.

The previously derived and indicated object is achieved according to the present invention in a sanitary purging device of the type mentioned above in that the device has a diaphragm with a single opening, which has a larger cross-section above than below,

The sanitary flushing device according to the invention ensures that a small part of the rinsing water is temporarily diverted during a rinsing process and can mix with cleaning agents and / or fragrances contained in the intermediate storage, while the majority of the rinsing water from the rinsing box goes directly through the flushing pipe into the sanitary basin is directed. After the main flow of the rinse water has flowed past the connection point, the mixture of cleaning agent or perfume and the diverted part of the rinse water flows from the intermediate storage and thus arrives last in the sanitary basin. It is achieved by a diaphragm with only a single opening, which has a larger cross-section than below, with simple means that the diverted into the buffer rinse water there has such a long residence time that, first, the main stream of rinse water has already drained into the sanitary basin , When the mixture flows out of the buffer, and secondly, there is a sufficient mixing of the rinse water with the additives.

According to an advantageous embodiment of the sanitary purging device according to the invention, the intermediate store is connected to the rinse pipe leading to the sanitary basin at a point at which the rinse water temporarily accumulates during a rinsing process. Preferably, the buffer is connected in the flow direction in front of or on a Spülrohrbogen the flushing pipe. Such Spülrohrbogen is usually provided at the lower end of the flushing pipe for connecting the vertical flushing pipe to the horizontal connection to the sanitary basin. This ensures that initially the majority of the rinse water from the cistern flows through the flushing pipe into the sanitary basin and there carries out the actual flushing, wherein a part of the accumulating rinse water is automatically diverted into the buffer to be there with a certain dose or To mix the amount of cleaning agents and / or fragrances. Once the accumulated flushing water has also drained into the sanitary basin, and the mixture can flow from the cache and thus forms the conclusion of the flushing process.

According to a further advantageous embodiment of the buffer is connected to a storage tank. The storage tank can be mounted in the wall, that is flush-mounted, or alternatively in the cistern, in the latter case, the storage tank is sealed against the particular rinse water, so that does not already result in the cistern mixing the detergent and / or perfumes with the rinse water , In both cases, the storage tank can be made accessible to the user in a simple manner by having an access flap is provided. This is particularly easy and comfortable to use if it has a soft-touch opening mechanism.

According to yet another advantageous embodiment, a pump is provided which can pump the cleaning agents and / or perfumes in the buffer. Preferably, the pump is integrally formed on the buffer. Furthermore, it can be provided that the intermediate store is formed directly or via a connecting piece on the flushing pipe, in particular on the flushing pipe bend. In this way, a preferably one-piece component, which can be replaced with a few simple steps against a conventional flushing pipe, in particular a conventional Spülrohrbogen.

According to yet another embodiment of the sanitary purging device according to the invention, the buffer is connected to a suction and / or ventilation line. At the end remote from the intermediate storage of the suction and / or ventilation line, a fan may be provided. In this way, the air can be sucked out of the sanitary basin and either out through an exhaust duct to the outside or, preferably via a filter, are returned to the room. So that the rinse water or the mixture with the additives from the buffer can not rise in the suction and / or ventilation line, a valve between the suction and / or ventilation line and the buffer is preferably provided, in particular a float ball or a flap valve.

According to yet another advantageous embodiment, a control device is provided via which automatically or Cleaning agents and / or fragrances can be placed in the cache. Preferably, the pump is controllable by the control device. In addition, it can be provided that the pump and / or the control device with a device for actuating the cistern, this is, for example, a lever or a button coupled. Finally, at least one sensor coupled to the control device, in particular a humidity sensor and / or a pressure sensor coupled to the toilet seat (toilet seat), can be provided to determine the optimum time at which the desired dose of cleaning agents and / or perfumes in the buffer should be given.

With the control device described above, it is possible, for example, to deliver the desired dose of additives, preferably automatically, during or after a rinsing process in the buffer. If the metered addition after a rinsing process, the additive remains in the buffer until the next flushing rinse water is diverted into the buffer and there mixed with the additives to a cleaning solution or fragrance solution. When dosing directly in a rinsing process, the time of dosing can be precisely determined via the sensor, which is arranged for example in the buffer or in the connecting piece to the flushing pipe.

There are now a variety of ways to design and develop the sanitary flushing device according to the invention. For this purpose, for example, referenced on the one hand to the Patent claim 1 subordinate claims, on the other hand, to the description of an embodiment in conjunction with the drawing.

a further embodiment of a diaphragm, which is not the subject of the present invention.

In Fig. 1 a sanitary flushing device 1 according to the present invention is shown. The Sanitärspüleinrichtung 1 has a cistern 4, in particular for flush mounting, and a device 2 for supplying cleaning agents, disinfectants and / or fragrances in a sanitary basin 3.

The cistern 4 is connected via a flushing pipe 6, which has a Spülrohrbogen 7 at its lower end, with the sanitary basin 3. At the upper end of the Spülrohrbogens 7 formed by a connector 10 branch to a buffer 5 for temporarily receiving a certain dose of cleaning agents and / or fragrances is provided.

The buffer 5 and the connecting piece 10 are connected in the flow direction S after the cistern 4 and in front of the sanitary basin 3 to the flushing pipe 6, that a portion of the rinse water during a rinsing the buffer 5 can flush temporarily. Since the connection to the flushing pipe 6 is selected in a region immediately in front of the flushing pipe bend 7 and during a flushing the flushing water flowing from the cistern 4 to the sanitary basin 3, accumulates in Spülrohrbogen to the junction of the connector 10, it is ensured that a part the rinse water enters the buffer 5.

The buffer 5 is connected via a pump 9 to a storage container or storage tank 8, which serves to receive a supply of cleaning agents and / or fragrances. The storage tank 8 is arranged in the present embodiment separately to the cistern 4 flush-mounted and has for the purpose of refilling with detergents and / or perfumes a revision flap (not shown) with a soft-touch opening mechanism.

The storage container 8 or storage tank is formed, for example, in such a way that therein a replaceable, detergent and / or perfume-containing container, in particular reusable container, e.g. in the form of a cartridge, bottle or bag, can be used.

Further, a control device 14 is provided, which controls the pump 9 so automatically that either directly during a flushing or immediately thereafter - this can be set individually - the pump a certain amount of cleaning, disinfecting and / or fragrances from the storage tank 8 in promotes the buffer 5. In this way, when flushing the intermediate store 5 with rinsing water, mixing with the corresponding dose of cleaning agent or perfume takes place.

It is also within the scope of the invention for the control device 14 to actuate the pump 9 when a sensor assigned to the control device 14, for example a pressure sensor coupled to the toilet seat, detects or signals the use of the toilet.

Subsequently, the mixture flows after the main stream of rinse water has already drained into the sanitary basin 3, also from.

Furthermore, a suction and / or ventilation line 11 may be provided, via which the air in the sanitary basin 3 can be sucked. For this purpose, a fan 13 is provided, which sucks the air from the sanitary basin 3 via the Spülrohrbogen 7, the connecting piece 10 and the buffer 5. The extracted air can be discharged unfiltered or filtered to the outside environment or preferably blown back into the toilet room or the toilet bowl via an odor filter.

In the present embodiment, the suction and / or ventilation line 11 is connected to the buffer 5 with a float ball valve, that while emptied buffer 5 and Spülrohrbogen 7 air can be sucked, but in the buffer 5 inflowing rinse water not in the suction and / or ventilation duct 11 can ascend.

It is also conceivable to use the suction and / or ventilation line 11 with the fan in the time in which the sanitary device is not used to distribute fragrances in the room, for example in the bathroom. For this purpose, the fan must be turned on only at a time in which a certain dose of perfume is in the cache.

Finally, in order to ensure that the rinsing water diverted into the buffer 5 can flow more quickly into the buffer 5 than the mixture of additives and flushing water generated there is discharged on the side of the buffer 5 facing the flushing pipe 6 and connected to the connecting piece 10 is, a corresponding aperture 15 is provided.

Fig. 2 shows some embodiments of such a shutter, which allows the rinse water flows faster into the buffer than it flows out again.

So shows Fig. 2a ) a usable within the scope of the present invention aperture 15 with a single opening 16 a, wherein the opening 16 a has a larger cross-section above than below. In this way, inflowing rinse water, which is under high pressure, flow largely unhindered into the buffer 5, but is prevented by the small cross section in the lower region of the opening 16a from flowing out just as quickly. In this way, there is sufficient time to mix the rinse water sufficiently with the located in the buffer 5 dose of cleaning agents and / or fragrances. Furthermore, the mixture is retained in the buffer 5 by the narrow lower cross section of the opening 16a in the buffer 5 until the main stream of flushing water has flowed through the flushing pipe 6 into the sanitary basin 3.

An alternative embodiment of an aperture 15 useful in the present invention is shown Fig. 2b ). Again, a single opening 16b is provided, the top has a larger cross-section than below. Unlike the in Fig. 2a ), the mushroom - shaped opening is the opening in Fig. 2b ) is triangular in shape, wherein a tip of the triangle faces downward and forms the lower, smaller cross-sectional area.

Fig. 2c Finally, Fig. 15 shows an aperture 15, which is not the subject of the present invention, with two openings 16c and 16d, the upper opening 16c having a larger cross-section than the lower opening 16d. Of course, instead of a single upper and / or lower opening, a plurality of openings may be provided as long as it is ensured that the cross section of the upper openings is greater than the cross section of the lower openings.
