The invention relates to a bidet/toilet combination () comprising: &#x2014;a toilet bowl () surrounding a bowl space (); &#x2014;a spray device () comprising a spray nozzle () located in the bowl space (); wherein the spray nozzle () is arranged and designed to adopt a rest position () and a use position (). The invention also relates to a method for operating said toilet and to the use of said bidet/toilet combination.

Automatic disinfection of the spray nozzle of a bidet/toilet combination

A method for detecting a leak, having at least the following steps: a) capturing a flow volume of a liquid through a liquid line during a multiplicity of liquid removal processes; b) comparing the flow volumes of the liquid in the respective liquid removal processes with an alarm value; c) outputting an alarm signal if the flow volume of the liquid in a liquid removal process exceeds the alarm value; d) adapting the alarm value on the basis of a frequency of the occurrence of the flow volumes of the liquid in the liquid removal processes above an adaptation value.

Method for detecting a leak in a liquid line, and water meter having a controller for carrying out the method

A method for detecting a leak in a fluid line, having at least the following steps: closing the fluid line with a valve to create a pressure chamber in the fluid line; determining a first pressure drop in the pressure chamber; opening the valve after completing the determination of the first pressure drop; closing the fluid line with the valve to create the pressure chamber in the fluid line again; determining a second pressure drop in the pressure chamber; and comparing the first pressure drop with the second pressure drop. Also, a water meter is provided with a valve, a flow sensor, and a pressure sensor, which are connected in a data-carrying manner to a controller, wherein the controller is set up to carry out the method according to the invention.

An installation unit for a bathroom, having at least one wall cladding element covering a bathroom wall. At least one transmitter unit having at least one associated transmitter antenna, which is part of a wireless power and/or signal transmission device, is disposed on the rear side, facing away from the visible side, of the wall cladding element. The transmitter unit can be coupled in a wireless power and/or signal transmitting connection to a receiver unit positioned in the bathroom.

A method for operating a sanitary fitting having a housing with a spout and a touch sensor, wherein in a touch mode of the sanitary fitting a tapping of a fluid can be activated by touching the touch sensor and wherein by touching the touch sensor for a period of at least 3 seconds, the touch mode is disabled. In addition, a sanitary fitting is specified, which controller is designed and provided for performing the method.

Method for operating a sanitary fitting

A thermostatic mixing valve for mixing cold water and hot water and for setting a mixed water temperature, having an electric motor that is controllable by a control unit and acts via a gear stage on a valve body, which is stroke-adjustable over a setting range and with which the mixing ratio between hot and cold water can be varied depending on a target mixed water temperature, presettable on the user side, and having a sensor element for detecting at least one set position in the setting range of the thermostatic mixing valve. The gear stage has a linearly adjustable linear displacement element, arranged rotationally fixed and provided between the electric motor and the valve body, and the sensor element works together with the linear displacement element to detect the set position.

Thermostatic mixing valve

A plumbing fixture at least having a first housing section and a second housing section which are arranged movable to one another, whereby the first housing section together with the second housing section forms an electrical sensor. In particular, an electrically conductive and simultaneously sealing coupling component is provided between the housing sections, whereby further an electrically conductive coupling component is provided between the first housing section and the second housing section and the coupling component comprises an electrically conductive plastic.

Plumbing fixture with electric sensor

An electronic control switch with at least two operating states for water faucets. The control switch has at least one control section, a base section, and a guide for a motion of the two sections relative to one another. At least one sensor is located in one section and at least two magnets are located in the other section, or alternatively at least two sensors are located in one section and at least one magnet is located in the other section, and each magnet associated with an operating state enters a detection region of a sensor at least at times in the course of the relative motion. The magnets at least have different magnetic field strengths or different spacings from the sensor.
