Definitions

  • 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.
  • the liquid can also be dispensed in a pulsating manner.
  • 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.
  • 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.
  • 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 At least one shower device for dispensing a liquid
  • 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.
  • intimate cleaning can be carried out using jets of liquid.
  • 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.
  • 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 moved mechanically and/or electrically or be adjustable.
