Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a perspective view of a WC attachment in accordance with the invention in the open state;

(2) FIG. 2 is a perspective view of the WC attachment of FIG. 1 with a cover; and

(3) FIG. 3 is a schematic view of a mounting plate for fastening the WC attachment to a WC bowl.

DETAILED DESCRIPTION

(4) FIG. 1 shows an exemplary embodiment of a WC attachment in accordance with the invention. The WC attachment includes a base plate 1, on which a valve 2, a shower device 3 and a water safety device 4 are arranged. The valve 2, the shower device 3 and the water safety device 4 are connected together by means of a conduit 5, which advantageously comprises a plurality of conduit sections.

(5) The valve 2 includes a water connector 6 and an actuating knob 7. The WC attachment is connected via the water connector 6 to a water conduit (not shown) for the supply of water. The water volume, which is to flow out of the shower device, is controlled by means of the actuating knob 7.

(6) The shower device 3 includes a stationary housing section 8 and a nozzle section 9, which is extendible under water pressure 9 and situated at whose end there is a nozzle 10. The water discharges from the nozzle 10 for cleaning purposes.

(7) Arranged between the valve 2 and the shower device 3 is the water safety device 4. The water safety device 4 includes an injector (not visible), from which a water jet is sprayed over a free section. Such a water safety device is preferably arranged horizontally. This means that the water jet goes horizontally over the free section. If water flows back, contamination of the mains water is excluded by the free space.

(8) In operation, leakage can occur at the water safety device 4. This leakage (or sprayed water or the like) is discharged through a channel 11 into the WC bowl.

(9) For this purpose, the base plate 1 includes an opening 12 into which the channel 11 discharges. The leakage flows into the WC bowl through the opening 12. The opening is arranged in the central third of the breadth of the base plate. The opening of the WC bowl has its maximum extent at this position.

(10) The channel 11 includes side walls 13 and is preferably constructed integrally with the base plate 1. The channel base 14 has a gradient towards the opening 12. Any water is thus reliably discharged without the risk of standing water.

(11) The water safety device 4 includes a spacer, which can preferably be constructed in the form of a grid 15, which discharges the sprayed water directly into the channel 11. The spacer has a height (maximum dimension) of at least 2 cm. This ensures particularly advantageously the maintenance of requirements specific to drinking water. The water safety device extends (in the present case with the grid 15) into the channel 11 and thus provides reliable interception of all sprayed water.

(12) The WC attachment is fastenable to the WC bowl by means of a fastening device. For this purpose, the WC attachment includes an actuating device 16, which is movable into engagement with a mounting plate 17 (see FIG. 3) preassembled on the WC bowl. The channel 11 extends over the actuating device 16.

(13) Incidentally, it is made clear again with reference to the coordinate system what is to be understood by the positional information top (O), bottom (U), front (V) and rear (or back) (H). These are consistent with the usual terminology relating to a WC. This applies also to the references to the shower device. It is also apparent from FIG. 1 that the water safety device 4 is arranged in the rear region of the base plate 1 and that the channel 11 extends forwardly from the rear.

(14) FIG. 2 shows the WC attachment of FIG. 1 with a housing cover 18. The WC attachment also includes two pivot pegs 19, 20, on which a WC seat is pivotally mounted. The pivot pegs are held stationary. Formed in the housing 1 is a lateral opening 21. This opening 21 is preferably aligned with the water safety device 4. As a result of this feature, the water safety device 4 is accessible through the opening 21, for instance for maintenance purposes, without the cover 18 having to be removed.

(15) FIG. 3 shows a mounting plate 17, which can be preinstalled on a WC bowl. The mounting plate 17 has two elongate holes 22, through which screws or threaded pegs (not shown) pass, with which the mounting plate is fastened to the WC bowl. The WC attachment is pushed onto the mounting plate 17. In order to anchor the base plate 1, the mounting plate 17 includes rail-like webs 23, which engage in corresponding recesses in the base plate.
