Floor drain for wet rooms

The invention relates to a floor drain for wet rooms, in particular For laboratories, operating theaters, etc., with a drain housing, in its upper inlet opening has an attachment piece supporting the inlet grate Is used adjustable in height, with an overflow edge in the housing on the outlet side for holding back a barrier liquid is provided in the lower housing area.

Floor drains of this type are known, but they have the disadvantage that in the area of the top pieces between the drain housing inner wall and the top piece outer wall for cleaning and disinfection inaccessible cavities arise. The bacteria that settle in these rooms and unpleasant smells can enter the unhindered Get wet room.

The invention is based on the object of a floor drain for wet rooms to create in which this disadvantage is avoided and the hygienic requirements and the related regulations can be met.

This object is achieved according to the invention in that the attachment piece is extended downward so far that it is immersed in the barrier liquid by approximately the amount prescribed for such processes. This measure has the advantage that the cavities, which were previously open to the wet space, no longer have a direct connection to the wet space due to the barrier liquid or the immersed lower part of the attachment piece. Bacteria that settle there and possibly multiply, do not survive the way through the barrier liquid, because this is provided with a sufficient amount of disinfectant, at least in operating theaters. Even soiled water can only penetrate these spaces to a very limited extent because the incoming liquid no longer splashes there.

If the drain is an embodiment that has a baffle upstream of the overflow edge, which is the prescribed amount is immersed in the sealing liquid and with a cleaning opening which can be tightly closed by a plug is provided, which provides access to the one behind the overflow edge Allow drain line, then this type of construction can be according to the invention design in an advantageous manner that the cleaning opening lies approximately at the level of the lower edge of the extension of the top section and forms the beginning of a cleaning channel, which is passed under the baffle and ends behind the overflow edge.

A cleaning channel that can be closed with a threaded stopper is Although known from AS 1 609 078, it extends in an arc from the overflow edge into the area of the grate frame. Such an arrangement of the cleaning channel is in this floor drain with the top piece extended downwards according to the invention not possible.

An exemplary embodiment and further advantageous configurations of the subject matter of the invention are shown in the drawing. Show it:

1 shows a floor drain with a downwardly extended top section and a cleaning opening with a cleaning channel,

2 shows a floor drain with an additional part and a cleaning opening inserted into the top piece to extend it downward with cleaning channel and / or cleaning opening in the dip wall.

The floor drain consists of a housing 1 open at the top with a Drain connection 2, a baffle 3, an overflow edge A, a Cleaning opening 5 with stopper 6 and cleaning channel 7 as well Top piece 8 with an insert grate 9. The top piece 8 can be adjusted vertically and laterally and is held by a rubber ring 10 pushed on with a friction fit. The housing 1 is expediently designed in its embodiment so that the amount of sealing liquid compared to previously known floor drains is enlarged by about twice. This ensures that the odor trap even in the event of suction part of the barrier fluid is fully effective. The top section 8, which is extended downwards, dips by the prescribed amount in the barrier liquid, which prevents bacteria from escaping backwards from the floor drain into the wet room.

In Fig. 2 two variants are shown. On the right side is, for example, an additional part to extend the top piece 8 11 inserted tightly.

The left half of FIG. 2 shows a height-adjustable additional part 12 to extend the top piece 8, which is sealed off from the top piece 8 with a lip seal IJ. For the limitation in the lowest installation position of the height-adjustable additional part 12, a rib is provided as a stop 14 in the longitudinal direction or the outlet direction on the cleaning channel or the bottom of the drain housing. In order to prevent the undesired complete expansion of the additional part 12, stops 15 are arranged to limit the height adjustment. At the upper edge of the additional part 12, cams 16 are attached as points of application for moving up and down. When using the height-adjustable additional part 12, a cleaning opening 17 can advantageously be recessed in the immersion wall 3 and closed with a stopper. This upper cleaning opening can also be provided ; it is accessible when the height-adjustable additional part is pulled into the uppermost position. In this case, however, the lower cleaning opening 5 and the cleaning

channel 7 completely dispenses with four den. As a material for manufacture Cast iron and / or plastic can be used for the Bodenatalaufes or the individual parts.
