  • Light source is generally understood as a signal generator or means, i.e. not only a means that has an optical effect, but also an acoustic one.
  • An active sensor 434 can be integrated into the soap dispenser 410, by means of which liquid soap is dispensed onto the hand when a hand approaches.
  • the soap dispenser 410 By triggering the soap dispenser function, the soap dispenser 410 is visually highlighted by the mesh network 428 and the resulting connection between the soap dispenser 410 and the towel dispenser 412 by activating lighting devices such as LEDs in the towel dispenser 412.
  • the color tone may differ from that which was initially emitted to guide the person to the soap dispenser 410.
  • a water tap is used before using the towel dispenser 412.
  • a visual highlight also includes or can be a temporal light modulation.
  • a temporal light modulation By using different wavelength ranges of the emitted radiation and/or the temporal light modulations, it is possible to display the states of a device depending on the desired or performed user action.
  • 416 multicolor LEDs are used as lighting sources, through which the visible wavelength range can be tuned and thus a desired wavelength range can be selected.
  • the towel dispenser 412 can be provided to dispense a paper section.
  • an active sensor 436 can be integrated into the towel dispenser 412, which dispenses a paper section when approached.
  • a section can also be pulled out by hand without automatically actuating the towel dispenser 412.
  • the trash can 414 is visually highlighted as a subsequent device by activating the lighting 416 integrated in it.
  • These are preferably also LEDs, such as multicolor LEDs.
  • the filling of the trash can 414 is detected by a sensor 438, which visually highlights and opens the door of the room or the door opener 420.
  • This visual highlighting can be achieved by LEDs in the door opener, i.e. lighting devices 416. This is only the case if the door opener is integrated in the mesh network.
  • the trash can 414 can have a closure that closes after trash has been thrown in. If the trash can 414 is not used, i.e. this device is bypassed, it will close automatically after a predetermined period of time after the upstream device has been used, e.g. device 412 in the form of a towel dispenser.
  • the door will open regardless when a person approaches, since there is a correspondingly active sensor for opening the door.
  • a hand dryer 418 is also installed in the washroom as a device that is basically not in use, so that there is no visual guidance to it. If, for example, the towel dispenser 412 no longer contains any paper, a user is visually guided to the hand dryer 418 by activating the lighting 416 integrated in it, such as LEDs.
  • the hand dryer 418 is switched on by means of an active sensor 440 and is switched off when the hand is removed or after a predetermined time. At the same time, communication with the door opener 420 takes place in the manner described above.
  • the devices 410, 412, 414, 418, 420 are connected to a storage device 422 in order to transmit and store data of the devices 410, 412, 414, 418, 420, be it with regard to the function of the devices 410, 412, 414, 418, 420, be it according to the scope of use, in order to forward corresponding data to a service center, in particular via a cloud 430, in order to carry out service activities in the washroom on the devices 410 and/or 412 and/or 414 and/or 418 and/or 420.
  • fragrance dispensers one or more flushes into the network.
  • a person does not have to be guided to a fragrance dispenser, for example, since the fragrance dispenser can be activated depending on the flush, for example.
  • the easy integration of the devices is possible due to the mesh network and the wireless connection of the nodes of the network.
  • the washroom can have several devices that perform the same function, such as towel dispensers, soap dispensers, etc. If one of these devices fails, the nearest one will be used based on the teaching of the invention.
  • Facility with the same function is activated as the facility to be used. This ensures route optimization.
  • washbasins each of which is assigned a soap dispenser and a hand dryer.
  • the soap dispenser of a washbasin is highlighted for the user, either visually or acoustically.
  • the primarily assigned paper dispenser in practice the one with the shortest walking distance, i.e. directly next to the washbasin, is activated.
  • the towel dispenser prefferably illuminated to enable guidance, for a paper section to be fed in advance to be used after washing, for the guidance through the washroom to be continued optically and/or acoustically after a section has been torn off, to name just a few examples. Any combination can be specified by parameterization.
  • each exit area will be illuminated and/or opened so that the used paper can be thrown in. If a trash can is used, the trash can lights will be reset. Before this, of course, the soap dispenser and towel dispenser will no longer be highlighted visually or acoustically.
  • the nearest local paper dispenser is activated.
  • the "replacement devices" are activated according to a failsafe list.
  • the fragrance dispenser 500 has a housing 502 in which a filter cassette 504 with filter 506, an air conveyor 508 and a cassette 510 with a medium to which a fragrance is supplied are arranged one above the other. This evaporates or evaporates due to the air flowing through the housing 502 in the direction of arrow 514, 516. The air first flows through the filter 506 and is cleaned in order to then flow through the medium that releases the fragrance, in particular in the form of a fleece.
  • a fragrance reservoir such as bottle 518, is located in particular in the housing 502, from which the fragrance is released drop by drop onto the fleece by means of a pump 520, such as a hose roller pump, via lines (not shown), such as hoses.
  • the housing 502 can have a cuboid shape, the side walls of which are formed by metal sheets that can be plugged together.
  • the side walls can have slots, holes or similar in order to attach the filter cassette 504 and the cassette 510.
