Description

The present invention relates to a functional unit for a shower toilet and a shower toilet with such a functional unit. Shower toilets of this type enable not only the absorption of bodily excretions, but also intimate hygiene by means of water jets.

Functional units serve in particular to accommodate functional components, such as a water inlet, a valve and/or a shower device for intimate hygiene. The functional components are arranged in particular on a carrier plate or base plate, via which the functional unit can be attached to a toilet ceramic appliance or a toilet bowl. A toilet seat and/or a toilet lid can also be rotatably attached to the functional unit. A liquid can be released as a spray jet through the shower device. In the case of particularly high-quality functional units, the liquid can also be dispensed in a pulsating manner. For this purpose, the shower device must be connected to a liquid pump, through which the liquid can be supplied to the shower device in a pulsating manner. This requires electronic components to control the liquid pump, which leads to high production costs for the functional unit.

The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to specify a functional unit for a shower toilet whose shower device allows liquid to be released in a pulsating manner and which is characterized by low production costs. In addition, a shower-toilet with a functional unit is also to be specified, with the shower device of which liquid can be dispensed in a pulsating manner and which is characterized by low production costs.

These tasks are solved with a functional unit and a shower toilet according to the features of the independent patent claims. Further advantageous refinements of the invention are specified in the dependent patent claims. It should be pointed out that the features listed individually in the dependent patent claims can be combined with one another in any technologically meaningful manner and define further refinements of the invention. In addition, the features specified in the patent claims are specified and explained in more detail in the description, with further preferred configurations of the invention being presented.

• - zumindest eine Duschvorrichtung zur Abgabe einer Flüssigkeit; und
• - zumindest eine rotierbare Unterbrechereinrichtung, durch die eine Zuführung der Flüssigkeit zu der Duschvorrichtung periodisch unterbrechbar ist.

A functional unit for a shower toilet that has at least the following contributes to this:

• - At least one shower device for dispensing a liquid; and
• - At least one rotatable interrupter device through which a supply of liquid to the shower device can be interrupted periodically.

The functional unit serves in particular to form an intimate cleaning function on a shower toilet. With the intimate cleaning function, after using the shower toilet, intimate cleaning can be carried out using jets of liquid. For this purpose, the functional unit can be fastened to a toilet ceramic appliance or a toilet bowl of the shower toilet, for example by means of a screw connection, latching connection or clamp connection. The functional unit can have functional components, such as a (liquid) connection for connecting a liquid supply line, a valve seat for a valve and/or a valve. The functional unit has at least one shower device for intimate cleaning. Liquid, in particular water, can be dispensed by means of the at least one shower device. The liquid can in particular be dispensed from the toilet bowl of the shower toilet in the direction of a user sitting on the shower toilet. For this purpose, the at least one shower device can have at least one dispensing nozzle for dispensing the liquid. The at least one dispensing nozzle can in particular be mechanically and/or electrically movable or adjustable. The functional unit has at least one rotatable interrupter device, through which a supply of liquid to the shower device can be interrupted periodically. For this purpose, the interrupter device is rotatably mounted, for example with and/or on a rotation axis. Furthermore, the interrupter device can be arranged at least partially in and/or on a liquid line, by means of which the liquid can be supplied to the at least one shower device. For example, the interrupter device can be designed in the manner of a disk and/or consist at least partially of plastic or metal, such as brass. In particular, the interrupter device can be designed in the manner of a circular disk. In this case, the interrupter device can have an outside diameter of, for example, 10 mm (millimeters) to 50 mm and/or (in particular parallel to the axis of rotation) a thickness of 0.5 mm to 5 mm. The liquid line can in particular be designed at least partially as a (flexible) hose line, pipeline and/or liquid channel. The supply of liquid to the shower device can be interrupted by the interrupting device, for example at a frequency of 0.5 to 50 interruptions per second. The frequency can depend in particular on a rotational speed of the interrupter device. The supply of liquid to the shower device is interrupted in particular mechanically, ie in particular not by controlling a liquid pump. Thus, no electronic control for the liquid pump is required to interrupt the supply of liquid, which reduces the manufacturing costs of the functional unit.

The at least one rotatable interrupter device can be drivable by the liquid. For this purpose, the rotatable interrupter device can in particular have a plurality of drive geometries, which can be designed in the manner of turbine blades, for example. Alternatively, the interrupter device can also be driven or rotated by means of an electric drive.

The at least one rotatable interrupter device can have a multiplicity of openings. The openings can extend through the interrupter device, in particular parallel to the axis of rotation. Furthermore, the openings (in particular orthogonal to the axis of rotation) can have a diameter of, for example, 1 mm to 10 mm. The interrupter device can have, for example, 2 to 50 openings.

The at least one rotatable interrupter device can be designed in the manner of an impeller. For this purpose, the interrupter device can in particular have a large number of wings. The vanes may extend radially outward relative to the axis of rotation. Furthermore, the vanes can be designed in the manner of turbine vanes.

The at least one rotatable interrupter device can be arranged at least partially in an injector. The injector can be arranged in it and/or on the supply line for the liquid. Furthermore, the injector can be connected to the at least one shower device via the supply line. The injector is arranged in particular in the functional unit, on the base plate and/or in a housing of the functional unit. In addition, the injector can extend along a longitudinal axis. The longitudinal axis runs in particular (substantially) horizontally when the functional unit is mounted on the shower-toilet or when the functional unit is in an operational state.

The injector may include a nozzle and a drogue. The liquid can be sprayed through the nozzle in particular in the direction of the drogue, so that the liquid can be caught by the drogue. The liquid can be dispensed through the nozzle in particular in the form of one, in particular a single, spray jet and/or full jet. The spray jet and/or full jet can be emitted through the nozzle, in particular with a jet diameter of, for example, 1 mm to 10 mm. The beam diameter can, for example, correspond at most to the diameter of the openings of the interrupter device. Furthermore, the liquid can be dispensed through the nozzle in particular in a (substantially) horizontal direction, parallel to the longitudinal axis and/or coaxial to the longitudinal axis of the injector. The liquid can be supplied from the drogue in particular to the at least one shower device.

The at least one rotatable interrupter device can be arranged at least partially in an air gap. The liquid can be sprayed through the nozzle into the air gap in particular in such a way that the drogue can be reached through the liquid, with the exception of the interrupter device, without contact with the injector and/or any other component of the functional unit. The air gap can in particular be a space through which the liquid can flow as a free jet. Due to the air gap, the injector can be designed in the manner of a pipe interrupter. Furthermore, the air gap can prevent the liquid, which may be contaminated by bacteria, microbes and/or viruses, from flowing back from the at least one shower device or the catch funnel to the nozzle if, for example, there is a negative pressure in the nozzle and/or the liquid supply line. The functional unit or the injector can be equipped with a so-called “AD air gap” for example according to DIN EN 13079 through its free outlet for the liquid and/or through the air gap.

The air gap may be formed between the nozzle and the drogue of the injector. The air gap (in particular parallel to the longitudinal axis) can have a length of, for example, at least 20 mm, preferably 20 mm to 30 mm. In addition, the air gap can extend from the nozzle to the drogue.

The invention and the technical environment are explained in more detail below with reference to the figures. It should be pointed out that the figures show particularly preferred embodiment variants of the invention, but that the invention is not restricted thereto. The same components are in the Figures provided with the same reference numerals. It shows as an example and schematically:

• 1 : a shower toilet with a functional unit in a perspective view;
• 2 : the shower toilet with the functional unit open;
• 3 : the functional unit in a perspective detailed view;
• 4 : a first injector of the functional unit in a perspective view;
• 5 : the first injector in a longitudinal section;
• 6 : a first embodiment variant of an interrupter device of the first injector in a plan view; and

The 1 shows a shower toilet 2 in a perspective view. The shower toilet 2 is attached to a wall 14 and has a functional unit 1 . The functional unit 1 is attached to an upper side 15 of a toilet bowl 13 of the shower toilet 2 . A toilet seat 16 is rotatably or foldably mounted on functional unit 1 .

The 2 shows the shower-toilet 2 with the functional unit 1 open. For this purpose, the shower-toilet 2 is without the 1 shown toilet seat 16 and without a cover 17 of the functional unit 1 shown. The functional unit 1 has a base plate 18 which is attached to the top 15 of the toilet bowl 13 and is used to accommodate functional components.

The 3 shows the functional unit 1 in a perspective detailed view. The functional unit 1 has a first shower device 3 and a second shower device 4 which are attached to the base plate 18 . The shower devices 3, 4 are used for intimate cleaning and each have a dispensing nozzle 19 for a liquid. The liquid can be fed to the first shower device 3 via a first injector 8 and to the second shower device 4 via a second injector 9 . For this purpose, the injectors 8 , 9 each have a liquid inlet 20 and a liquid outlet 21 . The liquid inlets 20 can each be connected to a liquid supply line, not shown here, via which the liquid can be fed to the injectors 8, 9 from a liquid source, for example a public water supply network. The liquid outlets 21 can each be connected to the shower devices 3, 4 by a liquid line, not shown here.

The 4 shows the first injector 8 in a perspective view. The first injector 8 has a nozzle 10 via which the liquid through an air gap 12 formed in an injector housing 22 of the first injector 8 to an air gap in the 5 shown drogue 11 of the first injector 8 can be sprayed.

The 5 shows the first injector 8 in a longitudinal section. The first injector 8 extends along a longitudinal axis 23 from the liquid inlet 20 to the liquid outlet 21. The liquid flows via a supply channel 24 of the first injector 8 to the nozzle 10 and is discharged from it as a liquid jet or full jet through the air gap 12 to the drogue 11 of the first injector 8 sprayed. For this purpose, the first injector 8 or the liquid inlet 20 of the first injector 8 can be connected to a liquid pump, not shown here. The liquid flows through the air gap 12 (essentially) parallel or coaxially to the longitudinal axis 23 of the first injector 8. The longitudinal axis 23 extends in an assembled state of the first injector 8 or in the 2 and 3 shown functional unit 1 (essentially) horizontal. The air gap 12 can prevent the liquid from flowing back from the liquid outlet 21 to the liquid inlet 20 . The Indian 3 The second injector 9 shown is identical to that in FIG 4 and 5 shown first injector 8 formed.

The 6 shows a first embodiment of an interrupter device 5 in the 4 and 5 shown first injector 8 in a plan view. The first embodiment variant of the interrupter device 5 is designed in the manner of a round disc which can be rotated about a central axis of rotation 25 . The axis of rotation 25 extends in the 6 perpendicular to the drawing plane. A plurality of openings 6 are formed in the interrupter device 5 coaxially around the axis of rotation 25 and extend through the interrupter device 5 parallel to the axis of rotation 25 . When assembled, the interrupter device 5 is in such a way in the 4 and 5 shown air gap 12 of the first injector 8 arranged that the axis of rotation 25 (essentially) parallel to the longitudinal axis 23 and the openings 6 at a rotation of the interrupter device 5 at least partially with the in the 5 shown longitudinal axis 23, the nozzle 10 and / or the drogue 11 can be aligned. The interrupter device 5 has a in the 6 rear drive geometries that are not visible, so that the interrupter device 5 can be rotated about the axis of rotation 25 during use by the liquid flowing through the air gap 12 or the liquid jet flowing through the air gap 12 . The rotation of the interrupters reinrichtung 5 leads to a periodic interruption of the supply of liquid to the in the 3 shown first shower device 3 or second shower device 4, because the liquid or the liquid jet in the 5 shown air gap 12 can only happen if at least one of the openings 6 at least partially with the in the 5 shown longitudinal axis 23, the nozzle 10 and / or the drogue 11 are aligned. If this is the case, the liquid or the jet of liquid from the in the 5 Nozzle 10 shown flow through the openings 6 to the drogue 11. Otherwise, the liquid or the jet of liquid hits areas of the interrupter device 5 formed between the individual openings 6, so that the liquid flows through a 5 shown lower side opening 26 of the first injector 8 in one in the 3 Shown drain channel 27 of the functional unit 1 can be redirected, through which the liquid in the 2 shown toilet bowl 13 bypassing the shower devices 3, 4 can be fed.

The 7 shows a second embodiment of the interrupter device 5 in the 4 and 5 shown first injector 8 in a plan view. The second embodiment variant of the interrupter device 5 is designed in the manner of an impeller 7 and can also be rotated about an axis of rotation 25 running perpendicularly to the plane of the drawing. The second embodiment variant of the interrupter device 5 has a multiplicity of vanes 28 which extend radially outwards relative to the axis of rotation 25 . The individual wings 28 extend obliquely to the axis of rotation 25 so that the interrupter device 5 can be rotated about the axis of rotation 25 by the liquid or the liquid jet. The rotation of the second embodiment of the interrupter device 5 leads, as in the first embodiment of the interrupter device 5, to a periodic interruption of the supply of liquid to the in FIG 3 shown first shower device 3 or second shower device 4.

The liquid can be dispensed in a pulsating manner by the functional unit 1 and at the same time the functional unit 1 has low production costs.
