WC Apparatus for Rail Vehicles

Abstract

A WC apparatus for rail vehicles is provided. The WC apparatus includes a flushing liquid tank, a toilet and a collecting tank. Further, the apparatus has control device which automatically initiates discharges of doses of disinfectants and/or calcification inhibitors into flushing water in order to keep a pH value below an associated threshold value.

1 .- 15 . (canceled) 
     
     
         16 . A WC (water closet) apparatus, comprising:
 a flushing liquid tank;   a toilet;   a collecting tank; and   a control device which automatically initiates discharges of doses of disinfectants and/or calcification inhibitors into flushing water in order to keep a pH value below an associated threshold value.   
     
     
         17 . The WC apparatus as claimed in  claim 16 , wherein the control device monitors a profile of the pH value and, when the associated threshold value is exceeded, initiates the discharges of disinfectants and/or calcification inhibitors into the flushing water. 
     
     
         18 . The WC apparatus as claimed in  claim 17 , further comprising:
 a sensor connected to the control device, the sensor measuring the pH value and transmitting the pH value to the control device.   
     
     
         19 . The WC apparatus as claimed in  claim 17 , wherein a first pH threshold value is between 6 and 7 and the control device discharges calcification inhibitors into the flushing water when the first threshold value is exceeded. 
     
     
         20 . The WC apparatus as claimed in  claim 17 , wherein a second pH threshold value is 8.0 and the control device discharges disinfectants into the flushing water when the second threshold value is exceeded. 
     
     
         21 . The WC apparatus as claimed in  claim 19 , wherein a second pH threshold value is 8.0 and the control device discharges disinfectants into the flushing water when the second threshold value is exceeded. 
     
     
         22 . The WC apparatus as claimed in  claim 16 , wherein the control device monitors a time profile of the pH value and, when a threshold value for a pH value increase is exceeded, initiates discharge of additional disinfectant into the flushing water. 
     
     
         23 . The WC apparatus as claimed in  claim 17 , wherein the control device is configured to adapt and optimize respective doses of disinfectants and/or calcification inhibitors for discharge into the flushing water on the basis of the profile of the pH value. 
     
     
         24 . The WC apparatus as claimed in  claim 23 , wherein the control device is configured to minimize a period for which the threshold value is exceeded for the purpose of optimization. 
     
     
         25 . The WC apparatus as claimed in  claim 18 , wherein the sensor is arranged in the collecting tank. 
     
     
         26 . The WC apparatus as claimed in  claim 25 , wherein a further sensor is arranged upstream of the collecting tank. 
     
     
         27 . The WC apparatus as claimed in  claim 18 , wherein a further sensor is arranged upstream of the collecting tank. 
     
     
         28 . The WC apparatus as claimed in  claim 16 , wherein the doses of disinfectants and/or calcification inhibitors are discharged directly into a flushing line. 
     
     
         29 . The WC apparatus as claimed in  claim 16 , wherein the doses of disinfectants and/or calcification inhibitors are discharged directly into the toilet. 
     
     
         30 . The WC apparatus as claimed in  claim 16 , wherein the control device is configured to initiate the discharges of the doses of disinfectants and/or calcification inhibitors based upon a degree of use of the WC apparatus. 
     
     
         31 . The WC apparatus as claimed in  claim 16 , wherein the control device includes a timer for initiating the discharge of the doses of disinfectants and/or calcification inhibitors into the flushing water at fixed intervals of time. 
     
     
         32 . The WC apparatus as claimed in  claim 30 , wherein the control device discharges firmly set doses of disinfectants and/or calcification inhibitors. 
     
     
         33 . The WC apparatus as claimed in  claim 31 , wherein the control device discharges firmly set doses of disinfectants and/or calcification inhibitors.
