Definitions

  • the invention relates to rail vehicles with toilets and toilet flushing devices and toilet flushing devices as such.
  • Buttons for manual actuation are widely used in all areas (toilets, washrooms, etc.) of modern rail vehicles to control doors, flush toilets, garbage can flaps, hand dryers, etc. Their appearance is partly determined by European regulations such as the TSI PRM (tactile symbols, tactile triggering).
  • Viruses and bacteria can spread from one user's hand to the next user's hand via the well-known buttons that are triggered by finger or palm pressure.
  • the object of the invention is to optimize rail vehicles with regard to hygiene in view of the problems described above.
  • the or at least one triggering device of the toilet flushing device can be actuated without contact.
  • An essential advantage of the toilet flushing device according to the invention can be seen in the fact that it is not necessary to touch parts of the triggering device for the purpose of triggering a flushing process and transmission of bacteria or viruses can be avoided.
  • the problem is solved in a simple and advantageous manner that passengers might find touching the toilet flush button unhygienic.
  • the triggering device comprises a proximity sensor which reacts to approach and generates a sensor signal when approached, and the triggering device controls the triggering of the flushing process at least also as a function of the sensor signal.
  • the triggering device enables gesture control by the user, with which the user can specify the amount of water for the next flushing process without contact.
  • the triggering device comprises a first proximity sensor which reacts contact-free when approached and generates a first sensor signal when approached, and the triggering device comprises a second proximity sensor which reacts contact-free when approached and when approached generates a second sensor signal, and the triggering device has a control device which is connected to the first and second proximity sensors and triggers different flushing processes depending on the chronological order in which the first and second sensor signals occur.
  • first and second are used here exclusively to distinguish between the proximity sensors and their sensor signals; they do not imply any priority or chronological order, which is why the “second” sensor signal can occur before or after the “first” sensor signal.
  • first and second amounts of water, durations and time periods.
  • the control device is preferably designed in such a way that it releases a first quantity of water for the flushing process when the first proximity sensor generates the first sensor signal and the second proximity sensor only generates the second sensor signal thereafter, preferably after the generation of the first sensor signal within a predetermined first period of time. and releases a second quantity of water for the flushing process if the second proximity sensor generates the second sensor signal and the first proximity sensor only generates the first sensor signal thereafter, preferably after the second sensor signal has been generated within a predetermined second period of time.
  • the first amount of water is preferably greater than the second amount of water; In the last-mentioned configuration, the first amount of water can be referred to as a large amount of water and the second amount of water as a small amount of water.
  • control device is designed in such a way that it enables the flushing process for a first period of time when the first proximity sensor generates the first sensor signal and the second proximity sensor only thereafter, preferably after the generation of the first sensor signal within a predetermined first period of time, generates the second sensor signal, and enables the rinsing process for a second period of time when the second proximity sensor generates the second sensor signal and the first proximity sensor only thereafter, preferably after the generation of the second sensor signal generates the first sensor signal within a predetermined second period of time.
  • the first period of time is preferably longer than the second period of time; In the case of the latter embodiment, the first period of time can be referred to as a long period of time and the second period of time can be referred to as a short period of time.
  • the first and second periods of time which should elapse at most between the sensor triggers in order to ensure the described differentiation between the different flushing processes, can be of the same length; alternatively, they may differ in length.
  • the or at least one of the proximity sensors is preferably an infrared sensor. In a preferred embodiment, all of the proximity sensors are infrared sensors.
  • the or at least one of the proximity sensors is structurally hidden and not visible.
  • all proximity sensors are structurally hidden and not visible.
  • the triggering device can be actuated both contactlessly and in a contact-controlled manner.
  • the triggering device includes a foot switch that can be triggered by touch and enables the triggering device to be actuated by foot.
  • the triggering device has a switch that indicates the locking status of a door assigned to the switch, and the triggering device triggers flushing when the switch Unlocking of the door, which is preferably the access door to the wet room equipped with the toilet, is signaled.
  • the triggering device (or its control device) only triggers a flush if no flushing has been triggered since the door assigned to the switch was last locked, for example because a user of the toilet or the wet room has flushed had forgotten.
  • a sensor that detects use of the toilet and generates a toilet use signal when use is detected.
  • a toilet use signal is preferably generated when a person is sitting on the toilet or alternatively already when the toilet lid is in the open position.
  • Such a sensor can also be referred to as a toilet use sensor.
  • the triggering device only triggers a flush after unlocking the door if the toilet usage sensor has used the toilet since the door was last locked has signaled the toilet using the toilet use signal, but no flush has been triggered by the time the door is unlocked.
  • the toilet flushing device is equipped with a pictogram that can be read tactilely is that explains or facilitates the operation of the toilet flushing device.
  • the invention also relates to a wet cell. According to the invention it is provided that this is equipped with a toilet flushing device as described above.
  • the invention also relates to a rail vehicle. According to the invention, it is provided that this is equipped with a toilet flushing device as described above or a wet cell as described above.

  • the dividing wall 21 separates a section 22 of the wet room 20 that can be entered or used on the passing side from an installation section 23 of the wet room 20 that is covered by the dividing wall 21 .
  • a toilet flushing device 40 is connected to the toilet 30 and is equipped with a triggering device 50 for triggering flushing processes.
  • the triggering device 50 is connected to a water source 60, which is, for example, a water tank - as in the figure 1 shown - can act, which is equipped with an electrically or mechanically controllable valve.
  • the controllable valve can be controlled by the triggering device by means of an electrical or mechanical triggering signal AS for the purpose of flushing the toilet 30 or for dispensing water.
  • the water source 60 can also be a controllable shut-off valve alone, which is connected to a water line (not shown) of the rail vehicle 10 and can be opened by the triggering device 50 using the electrical or mechanical triggering signal AS to flush the toilet 30.
  • the triggering device 50 includes a control device 70 which is connected to a proximity sensor 80 .
  • the proximity sensor 80 is preferably an infrared sensor or a radar sensor that emits an infrared or radar signal SS and generates a sensor signal S when a body part approaches, for example, and transmits this to the triggering device.
  • the proximity sensor 80 can be visible on the front - seen from the usable space section 22 - or hidden in the installation section 23.
  • a visually and tactilely readable pictogram 90 is preferably arranged, which reveals the existence of the proximity sensor 80 and visualizes the possibility of actuation by approaching a finger, for example.

  • first proximity sensor 81 and a second proximity sensor 82 which are arranged next to one another and spaced apart from one another.
  • the proximity sensors 81 and 82 can be arranged horizontally next to one another; alternatively, they can also be arranged vertically one above the other or completely differently.
  • the two proximity sensors 81 and 82 enable gesture control of the toilet flushing device 40 figure 4 recognize that a first sensor signal S1 can be generated contact-free by a hand movement in the direction of the first proximity sensor 81 and, subsequently, a second sensor signal S2 by pivoting the hand H in the direction of the second proximity sensor 82 and over it.
  • the control device 70 will preferably trigger different flushing processes as a function of the chronological order in which the first and second sensor signals S1 and S2 occur.
  • control device 70 can release a first, large amount of water for the flushing process if first proximity sensor 81 first generates the first sensor signal S1 and only then—within a predetermined maximum period of time—does second proximity sensor 82 generate the second sensor signal S2.
  • a second amount of water which differs from the first amount of water and is, for example, smaller than the first and is therefore called small amount of water below, is released, for example, for the rinsing process if first the second proximity sensor 82 generates the second sensor signal S2 and only then--within the predetermined maximum period of time--does the first proximity sensor 81 generate the first sensor signal S1.
  • the control device 70 can design the rinsing processes to have different lengths. For example, it can enable the rinsing process for a first, long period of time if the large amount of water is to be released, i.e. the first sensor signal S1 is generated before the second sensor signal S2, and the rinsing process for a second, short or shorter than the first period of time , release when the second sensor signal S2 is generated before the first sensor signal S1.
  • the figure 5 shows the two proximity sensors 81 and 82 as part of a gesture control by a finger F, which is moved from left to right past the two proximity sensors 81 and 82 and thus triggers a flushing process with the large amount of water and the long period of time.
  • the figure 6 shows - in a schematic plan view of the front of the partition 21 - a third exemplary embodiment of a wet cell 20 according to the invention of a rail vehicle 10.
  • actuating device 100 which reacts to manual contact and is therefore touch-controlled.
  • the actuating device 100 is connected to the control device 70 and this transmits an actuation signal BS1 when touched by the user and/or when the user exerts a contact pressure.
  • the control device 70 If the actuation signal BS1 is present, then the control device 70 generates the trigger signal AS for triggering a flushing process.
  • control device 70 triggers a rinsing process with the first large amount of water or the first, long rinsing duration when the actuation signal BS1 is present, i.e. the same rinsing process occurs as with a gesture control according to Figures 3 and 4 , so a triggering of the first proximity sensor 81 before the second proximity sensor 82, would have been the case.
  • the figure 7 shows the third embodiment in a schematic cross-sectional view.
  • the figure 8 shows - in a schematic cross-sectional view - a fourth exemplary embodiment of a wet cell 20 according to the invention of a rail vehicle 10.
